CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority under 35 U.S.C. 119 and 35 U.S.C. 365 to Korean Patent Application No. 10-2025-0031203) (filed on Mar. 11, 2025), Korean Patent Application No. 10-2025-0053921 (filed on Apr. 24, 2025), Korean Patent Application No. 10-2025-0133931 (filed on Sep. 17, 2025), and Korean Patent Application No. 10-2025-0157092 (filed on Oct. 27, 2025), which are hereby incorporated by reference in its entirety.BACKGROUND

[0002] The present disclosure relates to a target. The present disclosure relates to a method for fabricating a target.

[0003] Shooting and archery have expanded beyond the use of military to include self-defense, leisure, and sport purposes. A target may be something that is aimed at in shooting or archery. The target is needed not only during the day but also at night. To use the target even at night, an infrared target that radiates heat is provided. The infrared target may be easily detected by a thermal scope. The thermal scope may detect thermal energy (infrared) of an object to create an image, and thus, the thermal scope may detect the target even in complete darkness.

[0004] As inventions for the infrared target, cited inventions 1 (WO2015 / 119353A1; Thermal target board), 2 (US20200232769A1; Highly stable target sleeve identifiable to thermal weapon sights), and 3 (WO2023 / 104857A1; Method and device for reproducing a heat signature) may be exemplified.

[0005] Cited invention 1 provides a heating body at a central portion to narrow a range of infrared radiation. There is a limitation of high cost in providing a wide infrared target.

[0006] Particularly, to provide the heating body, a wire 30, a thread 32, and a heating paint 20 are provided. However, this technology is not realistic in terms of the difficulty of wiring the heating paint and the wires, a fabricating method, and fabricating costs. In addition, there is a limitation that it is not used in rainy weather due to a risk of electric leakage.

[0007] Cited invention 2 provides a thermal film layer 102 at the central portion. The thermal film layer 102 utilizes radiant heat by a film with low emissivity (less than 25% of identification number 102, etc.). Thus, there are limitations with weak infrared radiation and the inability to be used for a long period of time. In detail, energy incident into an object may be reflected, absorbed, or transmitted. Among these, the absorbed energy may be radiated as radiant heat. The radiant heat may be governed by the Stefan-Boltzmann law. Thus, it eventually loses the thermal radiation capacity after a certain period of time. Thus, the target has to be provided with a large energy storage layer. However, it eventually loses the radiation capacity. In addition, there is a limitation that the desired infrared performance is not maintained as a temperature gradually decreases.

[0008] Cited invention 3 uses a laser light source 2 to irradiate an image onto the target. Cited invention 3 allows the image to act as the target. The method may have a notable advantage in that it allows the target to have a specific shape. However, it is excessively difficult to provide a two-dimensional infrared shape of the target with a point light source. This is because it is difficult to transmit energy having a level at which the infrared radiation is emitted from the target. Thus, cited invention 3 may not be realistically applied in real life.SUMMARY

[0067] Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to the drawings. The idea of the present disclosure is not limited to following embodiments. A person skilled in the art who understands the spirit of the present disclosure may easily suggest other embodiments included within the scope of the same spirit by adding, changing, deleting, and adding components. However, this is also included within the scope of the spirit of the present disclosure.

[0068] The present disclosure may include a plurality of embodiments. A first configuration of a first embodiment among the plurality of embodiments may be included by adding or changing a component of another embodiment. The first configuration of the first embodiment among the plurality of embodiments and a second configuration of a second embodiment among the plurality of embodiments may be combined to provide another embodiment that is not specified in the plurality of embodiments.

[0069] In the description of the drawings, regardless of the reference numeral and symbol, identical or similar components are given with identical or similar reference numbers, and redundant descriptions thereof may be omitted.

[0070] The drawings are provided solely to facilitate understanding of the embodiments of the present disclosure, and the technical ideas of the present disclosure are not limited by the attached drawings. It should be understood that all modifications, equivalents or substitutes included within the spirit and technical scope of the present disclosure are included.

[0071] The suffixes “module” and “part” used in the description of the present disclosure for components are given or used interchangeably only for the convenience of writing the specification, and may not have a distinct meaning or role in themselves.

[0072] In describing the embodiments of the present disclosure, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present disclosure.

[0073] In describing the embodiments of the present disclosure, specific examples of the related known technologies may be included in the specification. In this case, the technical connection between the known technology and the present disclosure may be included in the technical idea of the present disclosure.

[0074] In this disclosure, it will be understood that although the ordinal numbers such as first and second are used herein to be described, various elements, these elements should not be limited by these numbers. The terms may be used to distinguish one component from another component.

[0075] It will also be understood that when an element is referred to as being “‘connected to” or “engaged with” another element, it can be directly connected to the other element, or intervening elements can also be present. On the other hand, it will also be understood that when any component is referred to as being ‘directly connected to’ another component, there is no intervening components.

[0076] The terms of a singular form may include plural forms unless referred to the contrary.

[0077] In this disclosure, terms such as “includes” or “has” are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification. Therefore, it does not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0078] In the present disclosure, in the case of a plane (including other surfaces such as a normal plane), it may refer to a surface that may have a certain engineering error rather than a mathematical absolute plane. For example, it may include a certain degree of bending. For example, if it is observed with the naked eye from a certain distance and recognized as the same plane, it may be recognized as a plane. The same is true for other mathematical names. For example, the direction may also include errors within the given engineering range. In the present disclosure, the target may refer to an object that is capable of being used for various purposes to attract attention.

[0079] In the present disclosure, the target may refer to an object as an object to be aimed at. In this disclosure, the direction may be relative to an observer. Therefore, a front side of an object or any direction may mean a direction adjacent to the observer in the object or direction, and a rear side of an object may mean a direction away from the observer in the object or direction.First Embodiment[Configuration of Target]

[0080] FIGS. 1(a) and 1(b) are a plan view and a schematic exploded perspective view, respectively, of a target according to a first embodiment. Descriptions will be made with reference to FIGS. 1(a) and 1(b). The first embodiment may be suitable for long-range targets.

[0081] A target T of the present disclosure may include a recognition area 1. The recognition area may be referred to as a portion that is recognized more prominently than other areas. The recognition area may include an area from which infrared rays are emitted. The recognition area may be placed on a predetermined same plane. The recognition area may radiate the infrared rays in a normal direction of the plane. The radiant heat of the recognition area may be recognized more prominently than other areas by a thermal scope. The recognition area may have a predetermined shape. Here, the shape may include a two-dimensional shape provided on the plane. Here, the shape may be provided by a heating body having a predetermined width, which is changed in its extension direction. Here, an inner area of the shape may provide a target area 2. For this, the heating body may be a planar heating body. The target area 2 may be provided adjacent to the inside of the shape. That is, the target area 2 may be disposed adjacent to the inside of the shape rather than the outside of the shape. Here, the shape may have a geometric center by maintaining a deflated shape. Thus, an observer may intuit that the target is defined at the geometric center of the shape. As a result, according to the target of the present disclosure, visibility of the observer may be greatly improved.

[0082] The target area 2 may be provided by the recognition area 1. The target may be an area that requires close attention and observation. The target area may be an area that is intended to be shot. For example, it could be an area where a bullet or arrow has to be shot. The heating body may be assumed to change an extension direction and to connect a virtual line connecting the heating body to both ends of the heating body. As a result, the inside of the recognition area may provide a two-dimensional inner area that is separated from the outside. Here, the two-dimensional inner area may be the target area. The target area 2 may be provided within the recognition area. A non-target area 3 may be provided outside the recognition area by using the recognition as a boundary.

[0083] The non-target area 3 may be an area that is not target. The non-target area may be an area that occurs incidentally, necessarily, or accidentally to provide the target T. For example, it could be an area on which a bullet or arrow is determined as being missed. The non-target area may not be provided. For example, the recognition area may be heated up to an edge of the target T. In this case, the non-target area is not provided.

[0084] The recognition area, the target area, and the non-target area may be named a recognition module, a target module, and a non-target module, respectively. However, the target T of the present disclosure is primarily viewed from a first direction from the perspective of the observer (including an unmanned aerial vehicle, a camera, and a robot). Thus, each area displayed on the first normal plane is defined to enhance convenience of understanding.

[0085] A relationship between the recognition area, the target area, and the non-target area is clearly explained.

[0086] In the expression of the recognition area, the target area, and the non-target area, the area may mean an area defined on a plane perpendicular to the first direction (e.g., +x axis). The recognition area may be placed on the first normal plane perpendicular to the first direction. The recognition area may extend with a predetermined width. Here, the width may be provided to be more than 10 times greater than a thickness. Here, the width may refer to a thickness direction perpendicular to the extension direction of the recognition area within the first normal plane. Here, the thickness may refer to a thickness of the recognition area in the first direction. The recognition area may have a first portion extending in a second direction within the first normal plane, and a second portion extending in a third direction within the first normal plane. The first portion and the second portion may be continuous. The first portion and the second portion may be in contact with each other. The other end of the first portion and the other end of the second portion may be spaced apart from each other.

[0087] The recognition area 1 may be electrically heated to radiate first light (e.g., infrared rays). Electricity may flow directly into the recognition area. Since the electricity flows directly like this, it is desirable that the recognition area not be shot by bullets. If the bullet shoots the recognition area, it may be judged to have missed. The recognition area may only recognize that the target area is therein.

[0088] The target area may be provided on the inner area of the first normal plane provided as the virtual line connecting both the ends of the recognition area and the recognition area. The virtual line may be provided singly. The recognition area may be one, and the virtual line may also be one. Thus, when the recognition area is the planar heating body 10, it may be provided as a single component. This will be described later. The inner area may be provided on at least one of the first normal plane, which is the same as the first normal plane in the first direction, and the second normal plane, which has a predetermined distance from the first normal plane in the first direction. In other words, the inner area may mean an area that is differentiated from the recognition area in response to observation in the first direction. Even if the first normal plane and the second normal plane have a predetermined gap in the first direction, the gap may be provided to be sufficiently small. As a result, when the observer observes the area in the first direction, the recognition area and the target area may be distinguished. That is, even if the first normal plane and the second normal plane are spaced a predetermined distance from each other in the first direction, when the recognition area and the target area are distinguished in response to observation in the first direction, the first normal plane and the second normal plane may be defined as the same normal plane. In this case, the first normal plane and the second normal plane may be referred to be the same plane in an engineering perspective. In some cases, it may not be the same plane in the engineering perspective. In this case, the embodiment is described separately.

[0089] The target area 2 may be an area on which the bullet has to be shot. The geometric center of the target area may be the most desirable priority target area. The target area may be further provided with a shape that displays the priority target area for each layer. The target area may radiate light (energy) in a form different from the recognition area. The target area may not be provided with a separate structure for infrared radiation. The visible light may be reflected or emitted from the target area.

[0090] The non-target area 3 may be placed outside the target area 2 with the recognition area 1 by using the recognition area 1 as a boundary. The non-target area may be an area on which attention has not to be focused. The non-target area may be an area on which it is not desirable to be shot. The non-target area may be an area that does not have to be shot.

[0091] The target T may include the planar heating body 10. The recognition area 1 may include the planar heating body. The observer may recognize the recognition area 1 by the heat generated by electricity from the planar heating body. The planar heating body has a predetermined thickness in the first direction, but may be provided with a large width, at least twice or more, preferably ten times or more, as the first normal plane. For this reason, it may be said to be a planar (normal plane) heating body. As already explained, the recognition area 1 may extend in the second and third directions from the first normal plane and may have a predetermined width. Thus, the visibility of the recognition area 1 may be provided to the observer. The planar heating body may be provided in a shape having a small upper portion and a large lower portion based on the drawing. For example, the small upper portion may be the head, and the large lower portion may be the torso. The shape that the planar heating body that is capable of being provided on the first normal plane may be various.

[0092] An electrode 10a may be provided at each of both ends of the planar heating body 10. Power may be supplied to the planar heating body through the electrode. The planar heating body may generate heat by the supplied power. The electrode may be made of brass or copper foil. A temperature sensor 16 may be provided adjacent to the electrode. A temperature measured by the temperature sensor 16 may be fed back to a controller 14. The controller 14 may detect the temperature to control the detected temperature to a target temperature. The temperature may correspond to a degree detected by the thermal scope. For example, the higher temperature may be considered to emit stronger infrared radiation, which will stand out in the thermal scope. For example, if the temperature detected by the controller is low, the power may be controlled to increase.

[0093] A protection plate 13 may be provided in front of the first direction from the electrode 10a. The protection plate may have a thickness of at least 10 millimeters or more. The protection plate may prevent the bullet from entering. The protection plate may protect the electrode 10a and its adjacent components. The components of the adjacent portion may include a wire and a connection part. This is because, if the connection wire and the connection part are disconnected, a complete power cut to the planar heating body 10 may occur. The controller 14 may be aligned with the protection plate 13 in the first direction. Thus, the controller 14 may also be protected in the same manner.

[0094] An insulator may be provided adjacent to at least one of a front or rear sides in the first direction of the planar heating body. Each of first and second insulators 11 and 12 may be provided in a shape corresponding to the shape of the planar heating body. At least a portion of the insulator 11 and 12 may be provided in contact with a plane in the first direction of the planar heating body. The insulator may be provided as a non-conductor. The insulator may be provided as at least one layer of non-woven fabric, flame-retardant non-woven fabric, hot melt, and PU hot melt. The planar heating body 10 and the insulators 11 and 12 may be used as a module and may be called a planar heating module 19. The planar heating module 19 may be said to have a structure added to prevent leakage from the planar heating body 10 through which current flows. Here, the current leakage may indicate that an external object is in contact with the wire of the planar heating body.

[0095] The first and second insulators 11 and 12 may be the same or different. The insulator may be provided to be larger than the width of the planar heating body to prevent the external object (e.g., water) from being in contact with the planar heating body. The pair of insulators 11 and 12 may seal inner and outer circumferences of the planar heating body. For this, a surface of the insulator may be provided with an adhesive layer. The adhesive layer may be provided at least on the surface on which pairs 11 and 12 of the insulators that are in contact with each other. The planar heating module 19 may block the external object from being introduced. Thus, the current leakage may be blocked. Here, the current leakage may indicate that water is introduced from outside, and the current leaks along with the water. As described above, the planar heating module 19 may achieve heat generation by external power and isolation from the outside, thereby preventing the current from leaking.

[0096] The planar heating module 19 may be connected to a plate 18. Here, coupling may be an example of attachment. An attachment member 17, which is an adhesive material, may be provided at a contact part between the plate 18 and the planar heating module 19. The attachment member 17 may be, for example, an adhesive tape. The planar heating module may be maintained in its shape on the plate and maintained in its shape against an external load by the attachment member. The plate may maintain a plane having certain rigidity. The plate may also be provided in the form of a predetermined frame. The frame may support the planar heating module. The frame may further include a component for providing the target area having specific target properties. The plate may be made of a resin material having a thickness with predetermined rigidity. The plate 18 may maintain the planar shape of the first normal plane when supported on an upper end. The plate 18 may not be able to maintain its shape when supported on a lower end.

[0097] A product in which the planar heating module 19 and the plate 18 are integrated may be called a target body 70. The target body 70 may be in a state excluding the configurations of the protection plate 13 and the controller 14. The target body 70 may be said to be in a state in which the target body 70 operates as a target by being connected to a power source.[Configuration of Planar Heating Body]

[0098] FIGS. 2(a) and 2(b) are views illustrating a first example and a second example, respectively, of a planar heating body. Descriptions will be made with reference to FIGS. 2(a) and 2(b).

[0099] According to the first example, the heating body may be the planar heating body 10, and the planar heating body may include a woven part 10b. The woven part 10b may be fabric including weft and warp yarns. Here, the warp and the yaw may be exemplified by wires through which electricity flows. The weft and warp yarns may be intertwined with each other. The woven part may extend in one direction. The one direction may refer to extending on a first normal line. The electrode 10a may be provided at both the extending ends of the woven part. The woven part may include a heating module having at least two warp yarns and weft yarns connecting the at least two warp yarns. The woven part may include at least two heating modules. The woven part may be provided with a plurality of weft yarns and a plurality of warp yarns.

[0100] The current may flow through the electrode. Here, the current may pass through the wire providing the woven part 10b to generate heat. The wire may generate ohmic heat due to electrical resistance. The heat-generating energy may be radiated as infrared rays.

[0101] According to the second example, the contents of the first example may be applied. In the second example, an additional woven part 10c may be provided in addition to the woven part 10b. In this case, the woven part 10b may be referred to as a first woven part, and the additional woven part 10c may be referred to as a second woven part. The weft and warp yarns of the second woven part 10c may be added between the weft and warp yarns of the first woven part. The second woven part 10c may be entangled with the first woven part. At least one of the weft or warp yarn of the second woven part may be thicker than at least one of the weft or warp yarn of the first woven part. Specifically, when a thickness of the weft yarn is thick, weaving stability may increase, and durability of the woven part may increase. When the thickness of the warp yarn increases, resistance may decrease, and thus, the heat generation may increase.

[0102] More detailed descriptions of the planar heating body are disclosed in the inventor's published patent KR20170055181A. In addition, various examples of the woven parts 10a and 10b are disclosed in KR20200166194A, which is filed by the inventor of the present disclosure. The technology disclosed in the two cited documents may be included in the present disclosure in terms of the detailed configuration of the planar heating body and connecting the planar heating body to the outside. Alternatively, this does not exclude other various implementation examples.[Configuration of Recognition Area]

[0103] The planar heating body may use metallic wires as the warp and weft yarns. Thus, when compared to fabrics using fine fibers, it was a difficult task to implement a predetermined width on the first normal plane. In other words, the planar heating body could not change the direction. For example, it was difficult to convert the extension in the second direction into the third direction. When forcibly changing the direction, there is a limitation that the wire is disconnected in a tensioned part and is cut in an overlapping portion. It should be noted that the planar heating body is bent inside the first normal plane. To solve this limitation, the inventor thought of folding the planar heating module 19. The inventor did not stop at just thinking about it, but conducted many experiments. Thus, a configuration providing the recognition area 1 was found.

[0104] FIG. 3 is an enlarged view illustrating a bent portion of the planar heating module. In FIG. 3, a shoulder portion of the torso portion is shown in drawing a, a head portion is shown in drawing b, and a lower end of the torso portion is shown in drawing c. Descriptions will be made with reference to FIG. 3.

[0105] The planar heating module needs to be bent while having a certain thickness. For this, the planar heating module 19 may be folded to change a bending angle. Here, the important point is that the bending is done within the first normal plane. Single regular folding of the wire was found to be had good resistant to cutting strength. Here, the folding may mean that top and bottom surfaces of the planar heating module are exchanged. The folding may provide various shapes of the recognition area 1 by varying in angle. Due to the folding, a portion at which the planar heating module overlaps in the first direction occurs.

[0106] In the shoulder portion a of the body, the planar heating module 19 may be bent at a wide angle. In this case, the folding angle of the planar heating module 19 may be greater than about 90 degrees and less than about 180 degrees. In the head portion b, the planar heating module 19 may be bent at a right angle. In this case, the folding angle of the planar heating module 19 may be about 90 degrees. At the lower end c of the body portion, the planar heating module 19 may be bent at a right angle. As described above, various shapes may be generated by changing the folding angle at the folded portion.

[0107] In the folded portion disclosed in FIG. 3, the overlapping portion in the first direction may be laminated into two layers in the first direction by folding the planar heating module 19. Here, the area on which the two layers are laminated may be called a double-layer area. The two-layer area may have a heat generation amount greater than that of the single-layer area. The high heat generation amount may mean that an intensity of the infrared rays is high. The folded portion may be defined by laminating the planar heating module 19 in at least three layers. FIG. 4 is a view illustrating another modified example of the folded portion. Descriptions will be made with reference to FIG. 4.

[0108] The planar heating module 19 may include three portions a, b, and c extending in different directions. Here, the three portions a, b, and c may be provided by folding the planar heating module 19. When the three portions a, b, and c are sufficiently adjacent to each other, the planar heating module 19 may provide the three-layer area 193 on which three layers are laminated in the first direction. The three-layer area 193 may provide a high heat generation amount in the first direction. Thus, the three-layer area may have a heat generation amount greater than that of the two-layer area. It may emit stronger infrared rays. The stronger infrared rays may mean greater visibility. The three-layer area, the two-layer area, and the area on which more layers are laminated may be called a multi-layered area. The multi-layered areas may be provided in various manners as needed. This may be one advantage of the present disclosure.

[0109] When the three portions a, b, and c are sufficiently adjacent to each other, the planar heating modules 19 may provide a shape area d by being adjacent to each other. The area that is not provided by only the width of the planar heating module 19 may be provided through the shape area. The width of the shape area may be greater than the width of the planar heating module 19. Here, the width may mean a straight-line distance connecting the target area to the non-target area within the recognition area 1. For example, a length of a first straight line connecting the target area to the non-target area at any point on the shape area 193 and a second straight line connecting the target area to the non-target area at any point other than the shape area may be compared to each other. At least one of the second straight lines may be longer than the first straight line. The shape area 193 may be provided to provide the target in more diverse shapes.

[0110] Instead of the planar heating module 19 being folded, only the planar heating body 10 may be configured to be folded. In this case, the insulators 11 and 12 may be provided on the top and bottom surfaces in the first direction of the planar heating body 10 having the folded portion. Thus, the current leakage due to the folding may be prevented.

[0111] FIGS. 5(a) and 5(b) are views illustrating an actual wild boar photo and a target fabricated with the planar heating module, respectively, as an example of a target fabricated by folding the planar heating module. Descriptions will be made with reference to FIGS. 5(a) and 5(b).

[0112] To provide the target T, the recognition area 1 may be provided with the planar heating module 19. Here, a plurality of folded portions may occur. The recognition area may extend along a boundary representing the wild boar. The recognition area has a certain thickness. Thus, sufficient visibility may be secured when using a thermal scope. Alternatively, the observer may recognize the recognition area as the wild boar.

[0113] A leg portion of the wild boar may be provided with the multi-layered area to provide the high heat generation amount. The leg portion of the wild boar may be provided with the shape area 193. Thus, the visibility of the wild boar's legs may be improved. The observer may more strongly recognize that a portion presented in a certain shape is the leg portion of the wild boar.

[0114] In the present disclosure, the recognition area may be an area on which a bullet does not have to be shot. Nonetheless, the bullet may shoot the recognition area 1 due to zero adjustment and firing errors. In this case, damage may occur to the planar heating body 10 providing the recognition area. Nonetheless, due to the configuration of the woven parts 10b and 10c, the planar heating body may not be opened. The woven parts may be provided by intersecting and intertwining each other. Thus, even if several warp and weft yarns at a specific portion are disconnected, current may flow through the warp and weft yarns adjacent to the specific portion. Thus, the current may continue to flow. The current may also flow through a portion extending in the extension direction of the planar heating body at the specific portion. Thus, the heating area of the planar heating body may not decrease, and the heating area may be stably maintained.

[0115] In other words, ohm heat may not occur in the specific portion. However, all portions spaced apart from the planar heating body at the specific portion in the extension direction may generate the ohmic heat.

[0116] FIGS. 6(a) and 6(b) are a view illustrating a rear surface of a plate when a recognition area is shot and an image of a thermal scope, respectively. Descriptions will be made with reference to FIGS. 6(a) and 6(b).

[0117] A situation S in which a plurality of bullet holes h occur is compared with a thermal image I in that situation S. Even in the situation S in which the plurality of bullet holes occur, it may be seen that the heat generation of the planar heating body is maintained overall.

[0118] In addition, a range of interest of the thermal image I may be enlarged. In this case, it may be seen that the planar heating body at a position spaced apart from the planar heating body by a predetermined distance in the extension direction of the planar heating body in the bullet hole h also uniformly generates heat in the width direction of the planar heating body.

[0119] Thus, even if the recognition area is shot, the planar heating body may operate until all normal planes at a specific point are cut off. Thus, there is an advantage in that the heating area of the planar heating body does not decrease, and the service life of the target body 70 is extended.

[0120] FIG. 7 is a view targets having various shapes. As illustrated in FIG. 7, the recognition area of the present disclosure may freely produce targets having various shapes. When providing a deer shape, an antler may be made using the shape area d.[Modified Example of End of Recognition Area]

[0121] The recognition area 1 may be provided as a planar heating module19. Both the ends of the recognition area 1 may be adjacent to each other. According to this, a single planar heating module may provide a more perfect shape. If two or more planar heating modules are required, fabricating costs may increase, and a structure may become more complex. The electrodes at the ends of the planar heating module are not in contact with each other. As a result, short circuit of the planar heating body may be prevented. The portions of the planar heating module may overlap each other in the first direction. Thus, a virtual line connecting the end of the planar heating module (which may also be understood as the planar heating body) to the end of the planar heating module (which may also be understood as the planar heating body) may have a modified example. FIG. 8(a) is a view illustrating a case a in which portions of the planar heating module do not overlap each other. FIG. 8(b) is a view illustrating cases b and c in which portions of the planar heating module overlap each other. FIG. 8(c) is view illustrating a case c in which ends of the planar heating module overlap each other as a modified example in which the ends of the planar heating module and a virtual line connecting the ends. Descriptions will be made with reference to FIGS. 8(a)-8(c).

[0122] Referring to FIG. 8(a), the virtual line connecting both the ends of the planar heating module may clearly define a single target area 2. This modification may be preferable to achieve the purpose of preventing the short circuit of the electrodes. This is because the pair of electrodes 10a are spaced apart from each other, and the portions of the planar heating body, which are adjacent to the electrodes, do not overlap each other.

[0123] Referring to FIG. 8(b), the extension parts of the planar heating modules may overlap each other in the first direction. The virtual line connecting both the ends of the planar heating module may be provided on the non-target area 3 or another target area 1. In this case, the original target area may be provided only by the planar heating module. The virtual line connecting both the ends of the planar heating module may provide another target area 1. This modified example may be desirable when responding to various shapes. However, there is a risk of the short circuit occurring if the bullet shoots a spot at which the portions of the planar heating body, which are adjacent to the electrodes, overlap each other.

[0124] Referring to FIG. 8(c), both the ends of the planar heating module may overlap each other in the first direction. In this case, the target area may be provided only with the planar heating module. This modified example may be desirable when responding to a variety of perfect shapes. However, there is a risk of the short circuit occurring if the bullet shoots a spot at which the portions of the planar heating body, which are adjacent to the electrodes, overlap each other. As the overlapping area becomes wider, there may be a limitation that the risk of short circuit increases.

[0125] The modified examples of the end of the recognition area may be selectively applied to each modified example to provide the various shapes of the target.Second Embodiment

[0126] In addition to the thermal scope, there is a night vision device as a method for identifying a target in dark places. The method for identifying the target in the dark places using the night vision device and the thermal scope is different in terms of its operating principles, possible operating environments, and image characteristics. In terms of the operating principles, the thermal scope detects infrared rays emitted from an object, and the night vision device amplifies and recognizes light reflected from the object. In the environments in which the operation is possible, the thermal scope may operate even in complete darkness, but the night vision device may only operate when there is even little ambient light. In terms of the image characteristics, a color of the thermal scope is black and white colors, but the night vision device is displayed as a green color. Due to the difference in characteristics, the thermal scope has an advantage of being able to identify the object even when fog or the like is present, but has a disadvantage of being unable to observe the object such as glass when the thermal scope is present. Although the night vision device have the advantage of being able to accurately identify the object, there is a disadvantage of not being usable in environments with no light.

[0127] The second embodiment presents an embodiment of a target that is suitable as the target for the night vision device. In the second embodiment, the configuration of the target of the first embodiment may be applied. For example, [Configuration of target], [Configuration of planar heating body], [Configuration of recognition area], and [Modified example of end of recognition area] may be the same as or similar to those of the first embodiment.

[0128] FIG. 9 is an image of the thermal scope as an experimental screen for explaining characteristics of a second embodiment. Descriptions will be made with reference to FIG. 9.

[0129] A portion a is a portion at which a metal plate with high reflectivity and low emissivity is placed, and a portion b is a portion at which a heating plate is placed. The metal plate may be placed on the heating plate. In an image acquired using the thermal scope, the portion a appears dark, and the portion b appears bright. This may mean that the portion a has a low temperature, and the portion b has a high temperature. Likewise, when using the metal plate with the low emissivity, even if the temperature is high, the temperature may appear low by the thermal scope that detects infrared rays. When the metal plate is used on the target area 2, heat may be transferred from the recognition area 1 to the target area. However, even if the target area is heated, visual differentiation from the recognition area may increase in the image of the thermal scope. The metal plate to the target area 2 may be applied to obtain greater visibility for the boundary between the recognition area and the target area when using the thermal scope.

[0130] A plate to which aluminum is applied may be used as the metal plate. The aluminum may be expected to have great applications due to its low emissivity (about 0.03 to about 0.08), ease of processing, low costs, and light weight. The aluminum may be used in the form of aluminum being deposited on a resin film.

[0131] FIG. 10 is a view illustrating a left side that illustrates a front view of the target of the second embodiment and a right side that illustrates an image I of the thermal scope as the target according to the second embodiment. Descriptions will be made with reference to FIG. 10.

[0132] The recognition area 1 may be provided with the planar heating module. The target area 2 may be provided within the recognition area. A metal plate may be provided on the plate 18 of the target area 2. The plate 18 may be coated with a metal thin film. The plate 18 may be coated with aluminum. At least a portion of the plate 18 may be exposed in a first direction (+x) without being covered by the recognition area 1. The metal plate material may be provided on a portion of the plate 18, which is exposed in the first direction (+x). The plate may reflect second light incident into the first direction (+x) in a fourth direction (−x). The plate may be a reflection plate. Here, the reflection plate may only act on the target area. The second light may be different light from the first light. The second light may include visible light.

[0133] The plate (using the metal plate) 18 has a plurality of holes h caused by shooting of the bullets. An image of the thermal scope clearly shows the holes h caused by the shooting of the bullets. This is because the thermal scope detects the infrared rays from the background after passing through the holes h. In most cases, the background may be adjacent to the target. As described above, when the target area 2 is the metal plate, a position to which the bullet is shot on the target area 2 may be accurately known. Thus, the shot position may be accurately determined. This is because, due to the low emissivity of the metal plate, it emits the infrared rays more prominently than the recognition area 1 and the background.

[0134] The target T may be observed with the night vision device. The plate may be observed with the night vision device. In this case, the metal plate (target area) may be observed more prominently than other adjacent areas (recognition area and non-target area). This is because the metal plate has high reflectivity. Non-woven fabric may be provided as the insulator 11 providing the recognition area 1. The non-woven fabric may be made of a black color material. In the recognition area 1, any black color material may be used for the externally exposed portion. In this case, the visual differentiation between the target area and the recognition area may be greatly enhanced. The reflectivity of the nonwoven fabric is lower than that of the metal plate. Thus, the target area 2 may be visually recognized more prominently than the recognition area 1.

[0135] In the second embodiment, the plate having high reflectivity and low emissivity was used on the target area. Thus, when observing the target with the thermal scope, the target area may be detected to have a lower temperature than an actual temperature, and thus, the visibility may be excellent. This is because the emissivity of the plate is low. When observing the target with a night vision device, reflected light of the target area may be greatly amplified, and thus, visibility may be excellent. This is because the reflectivity of the plate is high. According to the second embodiment, there is an advantage in that the target is used in any environment. Here, the environment may include an environment in which there is no light, and night vision device is not used, an environment in which there is an obstacle in a path of light, and the thermal scope is not used, and an environment in which the target is far away or small, and thus, the visibility of the recognition area is poor.Third Embodiment

[0136] The target may be used in various environments. Examples include long-range and close-range targets, and fixed and portable types. The third embodiment presents an embodiment suitable for use as a close-range target and portable. In the third embodiment, the configuration of the targets of the first and second embodiments may be applied. The third embodiment will be explained focusing on differences from other embodiments. For example, [Configuration of target], [Configuration of planar heating body], [Configuration of recognition area], and [Modified example of end of recognition area] may be the same as or similar to those of the first and second embodiments.

[0137] FIGS. 11(a), 11(b), and 11(c) are a front perspective view, a side view, and a rear perspective view, respectively, of a target according to a third embodiment. Descriptions will be made with reference to FIGS. 11(a), 11(b), and 11(c).

[0138] A predetermined board 20 is provided on a rear surface or at a rear side of a target body 70. The rear surface and the rear side may be a back or rear side of the plate 18 that is not visible to an observer. The board may be a rigid member having enough rigidity to maintain its shape and stand upright. The board 20 may be provided as a component of the plate 18. Here, it may be said that the component is integrated and thus does not need to be separated. The board 20 may use a material having a predetermined thickness, such as cork, to ensure convenience in processability and rigidity. The board 20 may use a plate-shaped material having a predetermined thickness, which is made of cork. The board 20 may be a cork board.

[0139] The recognition area 1 and the target area 2 may be provided on a front side of the board 20. The third embodiment may not provide a non-target area 3. A planar heating module 19 may be provided on the recognition area 1.

[0140] The target body 70 may maintain a shape of the target regardless of which a portion is held by using the board 20. That is, it is possible to maintain a posture perpendicular to the first direction seen by an observer. This may be a difference from the first and second embodiments. As an example, a protection plate 13 and a controller 14 may be provided at the front and rear sides of the target body 70, respectively. The protection plate 13 and the controller 14 may support the front and rear sides of the target body 70. Thus, the target body 70 may be erected. As an example, the protection plate 13 and the controller 14 are aligned in the first direction at a lower center of the target body 70. This is to prevent the target from being distorted in its posture when being shot. If the firm posture fixation is possible, the protection plate 13 and the controller 14 may be placed at any edge of the target body 70. Even if the target body 70 is shot, the bullet may easily break and penetrate the board. The target body 70 may be maintained in its upright state. The target body may be used as a target for multiple shootings.

[0141] The target of the third embodiment may be maintained in the upright state by itself. A size of the target may be provided to be carried to be approximately 30*20 centimeters in a first normal direction. The target has an advantage of being portable and ready for use after being mounted as needed.Third-1 Embodiment

[0142] The plate 18 may provide the target area 2. The planar heating module 19 may provide the recognition area 1. This is clear through the first to third embodiments. In addition, the plate 18 and the planar heating module 19 may be disposed together on the first normal plane. This is because there is no practical difference from an engineering perspective. The third-1 embodiment presents a case in which the target area and the recognition area are not considered to be on the same plane in the engineering perspective. In the third-1 embodiment, the configuration of the target of the third embodiment may be applied. This explains a differences between the third-1 embodiment and the third embodiment.

[0143] FIG. 12 is a side cross-sectional view of the target according to the third-1 embodiment. Descriptions will be made with reference to FIG. 12.

[0144] The planar heating module 19 is provided on a front surface of the board 20. The plate 18 is provided on a rear surface of the board 20. A portion of the board 20 corresponding to the plate 18 may be cut. The recognition area 1 and the target area 2 may be spaced apart by a distance equal to the thickness of the board.

[0145] In this case, it may not be said from the engineering standpoint that the recognition area 1 and the target area 2 are on the same plane. However, the target area 2 is placed on an inner area of the recognition area 1, and thus, the target area may be easily identified. This is because, as a result of the observer observing in the first direction, the target area 2 is recognized as being disposed on the inner area of the recognition area 1. In other words, when the observer observes the target in the first direction, both the recognition area 1 and the target area 2 may be placed on the first normal plane. The target of the present disclosure may have a configuration in which the target area 2 is disposed on the inner area of the recognition area 1 in response to the observer observing in the first direction. The results are the same in this embodiment.

[0146] The target body 70 may be upright by a supporter 31. The supporter 31 may be provided in a groove, and the target body 70 may be fitted into the groove. The supporter 31 may include a protection plate and a controller. The protection plate and the controller may be coupled to each other to provide the supporter 31.Fourth Embodiment

[0147] The plate 18 may correspond to the target area 2, and the planar heating module 19 may correspond to the recognition area 1. As a result, the plate is a frequently discarded item that is shot by a bullet, and the planar heating module 19 is a non-shot item. The planar heating module is an expensive item compared to the plate. The inventor studied a technology that enables the planar heating module to be used for a long period of time. As a result, the inventor arrived at the fourth embodiment. The fourth embodiment presents an embodiment in which the planar heating module is used repeatedly. In the fourth embodiment, the configurations of all the embodiments may be applied. A specific example is explained by exemplifying the third-1 embodiment.

[0148] FIG. 13 is a perspective view of the target according to the fourth embodiment. Descriptions will be made with reference to FIG. 13.

[0149] The plate 18 and the board 20 may be provided as separate components. That is, the board is not a component of the plate and is different from that of the third embodiment.

[0150] The plate and the board may be separate components for a separate target. In this case, the plate 18 may be referred to as a first plate, and the board 20 may be referred to as a second plate. That is, the two components can cooperate to perform a function of the plate 18. The first plate 18 may provide a target area, and the second plate (i.e., board) 20 may maintain a shape and form of the recognition area (including the planar heating body) 1. The description in this paragraph may also be applied to other embodiments in which the roles of the plate 18 are separated.

[0151] Fasteners 181 and 182 that are easy to be coupled and separated (free enough to be removed by the hand) may be provided on a surface on which the plate and the board face each other. The fastener may include a surface fastener (e.g., Velcro 181 and 182 (registered trademark), adhesive, etc.), a hook, and a screw. The first plate 18 may be coupled to the second plate 20 by the fastener.

[0152] When the target area 2 is cut off, and the use thereof is terminated, the plate may be removed and discarded, and a new plate may be attached. Thus, the planar heating module may be used repeatedly. As a result, a product may be used for a long time.

[0153] An embodiment in which the fastener is applied is possible even when the board 20 is not present. For example, the planar heating module 19 may perform the role of the board. For example, the fastener may be attached to the rear surface of the planar heating module and the front surface of the plate.Fifth Embodiment

[0154] The target may be used in various environments. For example, the target may be used in rainy and high-humidity environments. Since the planar heating module 19 conducts electricity, there is a great need for sealing. The target requires a production of large quantities of the same product. The fifth embodiment proposes a target that satisfies universal usability and mass production. In the fifth embodiment, the configurations of the targets of the first to fourth embodiments may be applied. The fifth embodiment will be explained focusing on the differences from other embodiments.

[0155] FIG. 14 is a plan view of the target according to the fifth embodiment. Descriptions will be made with reference to FIG. 14.

[0156] The target may be said to be a plate-shaped member extending along a first normal line. The plate 18 is placed at a center of the target as the target area 2. The planar heating module 19 is placed on the periphery of the target as the recognition area 10. Inner and outer circumferences of the planar heating module 19 may be sealed. Both surfaces of the planar heating module 19 may be sealed. A wire 52 may be drawn out between the sealed surfaces. The wire 52 may be connected to an electrode 10a of the planar heating body 10. The plate 18 may be coupled to any surface of the planar heating module 19. The planar heating module 19 and the plate 18 coupled to each other to provide the target body 70.

[0157] In the planar heating module 19, a width of the planar heating body 10 may be smaller than a width of each of the insulators 11 and 12. Inner surfaces of the insulators 11 and 12 may be coupled to each other with the planar heating body therebetween. The pair of insulators have a first portion that is not in contact with each other due to the intervention of the planar heating body. The pair of insulators have a second portion that is in contact with each other without the intervention of the planar heating body. The second portion may be coated with an adhesive. The second portion may be coated with an adhesive. The planar heating module may be sealed by the second portion. An adhesive or adhesion agent may also be applied to the first portion. Thus, the planar heating body may be firmly fixed.

[0158] The target, particularly the target body 70 used for the target, may be fabricated through a mass production process. The target may be prevented from leaking.

[0159] FIGS. 15(a)-15(g) are views for explaining a process of fabricating a target body. Processes shown in FIGS. 15(a) to 15(f) may be sequentially performed. Descriptions will be made with reference to FIGS. 15(a)-15(g).

[0160] Descriptions will be made with reference to the process (a). The planar heating module 19 may be provided folded into a predetermined shape on one surface of a protective film 11a. The protective film 11a may be provided as a component of the insulator 11. The protective film 11a may be a PU film. Any one layer of the protective film may include a material layer having high emissivity. Any one layer of the protective film may include a base layer. Any one layer of the protective film may include an adhesive layer. An adhesive or adhesion agent may be applied to an attachment layer.

[0161] A temporary assembly tool 51 may be coupled to a folded portion of the planar heating module 19. Here, the planar heating module 19 may include an insulating layer such as non-woven fabric and may exclude the protective film 11a. The temporary assembly tool 51 may be exemplified by a tape. The temporary assembly tool 51 may be pressed against the folded portion so as to be in close contact with the protective film 11a. The temporary assembly tool 51 may prevent the folded planar heating module 19 from being unfolded. This may prevent defects from occurring in the subsequent pressing process. The temporary assembly tool 51 may be provided at all places at which the planar heating module is folded.

[0162] Descriptions will be made with reference to the process (b). The wire 52 may be connected to the electrode 10a. The place at which the electrode 10a and the wire 52 are connected may be coupled to the temporary assembly tool 51. The temporary assembly tool 51 may allow the electrode 10a and the wire 52 to be in close contact with the protective film 11a. This may prevent defects from occurring in the subsequent pressing process.

[0163] Descriptions will be made with reference to the process (c). Another protective film 12a is covered on a top surface of the temporary assembly tool 51. The protective film 11a and another protective film 12a may be the same product. The protective film 11a and another protective film 12a may be attached to each other while placing other components therein. For this, the adhesive or adhesion agent may be applied between the protective film 11a and another protective film 12a.

[0164] Descriptions will be made with reference to the process (d). Thereafter, the planar heating module 19 may be sealed by pressing the protective film 11a and another protective film 12a. The pressing process may use a press that applies a pressure and heat. With the planar heating body 10 placed at a center, both the inside and outside of the planar heating body 10 may be sealed. A process (e) shows an intermediate body that has completed the process to date. In this state, intrusion or damage by an external object may be prevented. In the state of the intermediate body, long-distance movement and transportation may be possible.

[0165] Descriptions will be made with reference to the process (f). Thereafter, an inner area of the planar heating module 19 may be cut off. The target area 2 may be provided later on the cut-off area. A recognition area 1 may be provided outside the target area 2.

[0166] Descriptions will be made with reference to the process (g). The attachment member 17 may be attached to any surface of the recognition area 1 in the intermediate body. The attachment member may be a double-sided tape. The double-sided tape may have adhesive properties on both surfaces. Any one surface of the attachment member 17 may be attached to the recognition area 1. Thereafter, after removing a release paper on the other surface of the attachment member, the plate 18 may be attached.

[0167] When the process is completed, the target body 70 of FIG. 14 may be provided.Sixth Embodiment

[0168] The target of the present disclosure may be used as a portable short-range target. In this case, the purpose may be to protect the controller, facilitate the assembly, and maintain the vertical direction with respect to the first direction. For example, a process of connecting the protection plate 13, the target body 70, and the controller 14 of the third embodiment is required. The sixth embodiment is described by citing the third embodiment, but is not limited thereto, and the configuration of the targets of the first to fifth embodiments may be applied.

[0169] FIG. 16 is a view for explaining a process of fabricating the target according to the sixth embodiment. Descriptions will be made with reference to FIG. 16.

[0170] The target body 70 may be placed at the center, and also, the protection plate 13 may be placed on the front surface (+x side), and the controller 14 may be placed on the rear surface (−x side). Any edge of the target body may be placed between the protection plate and the controller. A screw may be fastened from a rear side of the controller 14 toward a front side (+x direction). The screw may fasten all the controller, the target body, and the protection plate. The protection plate and the controller may have the same or similar height. Thus, each of the protection plate and the controller may become a supporter 31. For fastening the screw, a recess 61 may be provided in the protection plate 13. For fastening the screw, a recess 62 may be provided in the controller 14.

[0171] The controller 14 may be provided with a connection terminal 64 to which the wire 52 is connected. The connection terminal 64 may be provided with a button and a hole. The hole may be opened with the button, the wire 52 may be inserted into the hole, and the button may be closed. With this operation, the connection between the connecting terminal and the wire may be completed. Disconnecting the connection terminal from the wire may be performed in an opposite operation.

[0172] The controller 14 may be provided with a battery mounting part 65. The battery may provide required power by using a plurality of commercially available AA or AAA batteries.

[0173] A power switch 63 may be provided in the controller 14. The power switch may control heat generation (which may include an amount of heat generated) of the planar heating body through an on / off operation. When the connection is completed, and the power switch is turned on, an operation of the target may be initiated. The operation of the target may include sustaining a predetermined amount of heat. Alternatively, the initiation of the target operation may include a heating operation of the planar heating module.

[0174] According to this embodiment, the controller may be safely protected by the protection plate. According to this embodiment, the components may be brought in a separated state and simply assembled and used on the site. According to this embodiment, since the commercial battery is used, the power not only may be conveniently supplied anywhere, but the battery may also be conveniently replaced and used. According to this embodiment, an upright state may be well maintained. According to this embodiment, the screw may be separated to conveniently replace the component.Seventh Embodiment

[0175] The present disclosure provides an embodiment in which characteristics of the target area are changed. In the second embodiment, the target capable of responding to both the thermal scope and the night vision device is presented. An output of the recognition area may be adjusted to correspond to specifications or operations of the thermal scope. It is not easy to cope with the specifications or operations of the night vision device. In the fourth embodiment, the Velcro is suggested, but this may be limited to short-range and targets. This embodiment proposes an embodiment in which the target area varies in response to the night vision device. Any explanation insufficient in the description of this embodiment may be applied as is to the description of the first to sixth embodiments.

[0176] FIGS. 17 and 18 are views illustrating the target according to the seventh embodiment. In FIG. 17, the target may have both a head and a torso. In FIG. 18, the target may have a head and chest. This will be described with reference to FIGS. 17 and 18.

[0177] The target body 70 may be provided in a pocket shape with an opened front surface. The planar heating module 19 and the plate 18 may have at least a portion of an outer circumference having the same shape. The outer circumferences of the planar heating module 19 and the plate 18 may be provided with the same shape. The outer circumferences of the planar heating module 19 and the plate 18 may be coupled to each other. Some portions of the outer circumferences of the planar heating module 19 and the plate 18 may not be coupled to each other. A portion of each of the outer circumference of the planar heating module 19 and the plate 18, which is not coupled, may provide an opening hole 71. The opening hole 71 may be provided at a lower end with respect to the direction of gravity. As described above, in the state in which the portions of the outer circumferences of the planar heating module 19 and the plate 18 are coupled to each other, a remaining outer portion may be coupled, and thus, the planar heating module 19 and the plate 18 may provide the pocket shape. The pocket shape may mean that an external object enters and exits through the opening hole 71.

[0178] The planar heating module 19 may correspond to the recognition area 1. The inner area of the recognition area 1 may be opened. Through the opened inner area, the plate 18 may be observed in the first direction. The plate 18 may be the target area. Any portion of the plates 18 may overlap the planar heating module 19 in the first direction. The overlapping portion may not function as the target area. It may be seen that any portion of the plates 18 do not become the target area 2. Another portion of the plates 18 may not overlap the planar heating module 19 in the first direction. At least another portion of the plates 18 may correspond to the target area 2. The plate 18 may correspond to the target area 2. An external area of the recognition area 1 may correspond to a non-target area 3. In the target of this embodiment, in response to observation in the first direction, the target area 2 may be provided on an inner area of the recognition area 1. In other words, the recognition area and the target area may not be placed on the same plane strictly. Nonetheless, in response to observation in the first direction, the recognition area, the target area and the non-target area may be placed together on the first normal plane.

[0179] The target body 70 may be connected to the controller 14 by a wire 52. Power consumption may vary depending on a size and specifications of the target body. The wire 52 may have a predetermined length (e.g., about 6 meters). The wire may include a sealed waterproof connector.

[0180] The controller 14 may include a temperature controller. The controller 14 may include a battery. A heating state of the planar heating module 19 may be controlled according to a control of the controller.

[0181] A standing body for supporting the target body 70 may be inserted into the opening hole 71. Here, the standing body may not obstruct the plate 18 from being observed in the first direction. For example, an observer may recognize the plate 18 as the target area 2. In this case, the plate 18 may be a first plate (see the fourth embodiment). In this case, a standing body may only function as a second plate (see the fourth embodiment).

[0182] The standing body (e.g., see reference numeral 81 of FIGS. 20(a)-20(h)) that has the target area 2 may be inserted into the opening hole 71. The standing body may have a wide surface corresponding to a size of the opening hole 71. The standing body may be supported on the ground or on a wall. In the standing body, a portion inserted into the opening hole 71 may provide the target area 2. The target area may use materials having various reflectivities. A variety of materials including wood, ceramic, plastic, and a metal may be used. Various materials may be used as the metal, including aluminum, copper, iron, and stainless steel. Thus, the target may be used in various forms to suit an operational state of the night vision device.

[0183] Even without the standing body, the target body 70 of this embodiment may be used as the target. For example, it may be used by fixing the periphery.

[0184] FIG. 19 is a cross-sectional view of an adjacent position of the opening hole, which is taken along an extension direction of the opening hole. That is, FIG. 19 is a cross-sectional view taken along line 19-19′. Descriptions will be made with reference to FIG. 19.

[0185] The plate 18 of the target body 70 of the seventh embodiment may use a waterproof material. The waterproof material may be waterproof cloth made of cloth. The waterproof cloth may have predetermined reflectivity. The waterproof cloth may provide the target area 2. The waterproofing cloth may block water introduced from a rear side. Thus, the target may be used even in bad weather.

[0186] As described, an inner portion of the recognition area 1 provided by the planar heating module 19 may be opened. Through the opened portion, the waterproof cloth (the waterproof cloth may be the plate 18) may be exposed forward in the first direction. A connection part between the plate 18 and the planar heating module 19 may be maintained airtight. Outer circumferential portions of the plate 18 and the planar heating module 19 may be connected to each other. Waterproof fabric may be used at the connection part between the two members. The fabric may use narrow-width fabric 75. The narrow-width fabric may be further treated with water-repellent and water-pressure resistant processing to enhance waterproofing effects. Thus, water may not be introduced through the connection part between the two members. Thus, the target may be used even in bad weather.

[0187] Waterproof resins 11c and 12c may be further used as components of the insulating layers 11 and 12. For example, the resin may be made of thermoplastic polyurethane (TPU). The waterproof material resin may prevent water from being introduced.

[0188] An adhesive or sealing material may be further added between surfaces on which the plate 18 and the planar heating module 19 are in contact with each other. Thus, leakage current from the planar heating body 10 may not occur.

[0189] The contact points of the plate 18 and the planar heating module 19 may be spaced apart from each other. Thus, the opening hole 71 may be provided. A member providing the target area 2 may be inserted and withdrawn through the opening hole. According to this embodiment, the target area of the target body may actively vary in response to the night vision device. According to this embodiment, the target body may be used even in bad weather.Eighth Embodiment

[0190] The present disclosure provides embodiments that are capable of improving the above-described sense of shooting. In the seventh embodiment, a member that generates striking sound may be used as the standing body that is inserted into and removed from the opening hole 71. Thus, when a bullet hits the target area, the fact of the shooting may be detected by the sound. Any explanation insufficient in the description of this embodiment may be applied as is to the description of the seventh embodiment.[Method for Coupling Target]

[0191] FIGS. 20(a)-20(h) illustrate how to use the target according to this embodiment. The processes in FIGS. 20(a) to 20(h) are sequentially performed. Descriptions will be made with reference to FIGS. 20(a)-20(h).

[0192] First, the standing body 81 will be described. A rigid plate may be used as a material for the standing body 81. The rigid plate may be provided by using a metal plate. The metal plate may be provided with a protrusion 82 that amplifies impact sound when being shot. The standing body may have a rigid plate having the same shape as an outer circumference of the target body 70 in the first direction. An outer circumference of the standing body may be slightly smaller than that of the target body 70. This is to ensure that the standing body is inserted. The standing body may be inserted into the pocket-shaped target body 70. The target body 70 may be upright by the standing body 81. The standing body may be likened to a person, and the target body may be likened to clothing.

[0193] The standing body 81 may provide first and second plates (see the fourth embodiment). The standing body 81 may provide functions of the first plate and the second plate together. In this case, the target body 70 may also provide a first plate. In other words, the plate (here, waterproof cloth) 18 of the target body 70 may provide the first plate that provides the target area 2. However, the standing body 81 may be shielded after being coupled. In other words, the plate 18 may be observed by an observer in the first direction and recognized as the target area. Depending on the usage aspect (i.e., a state in which the standing body is inserted into the opening hole), the plate 18 may be shielded in the first direction by the standing body 81. In this case, the standing body 81 may provide the target area. In this case, the standing body 81 may provide functions of the first plate and the second plate together.

[0194] The standing body 81 may operate as a portion of a popper system. The popper system may be said to be a system that has a function of falling when a bullet is shot. The standing body may make sound when shot and fall over. Here, the standing body 81 may include the rigid plate inserted into the target body 70.

[0195] Descriptions will be made with reference to FIG. 20(a). The standing body 81 is inserted through the opening hole 71 of the target body 70. The inserted portion of the standing body may include the rigid plate. When observed in the first direction, the standing body and the target body may have the same shape. The standing body may be slightly smaller in size than the target body.

[0196] Descriptions will be made with reference to FIG. 20(d). The standing body may be smoothly inserted into the inside of the target body due to the difference in size of the target body.

[0197] Descriptions will be made with reference to FIGS. 20(c) and 20(d). When the standing body is completely inserted, a portion of the standing body 81 may be exposed in the first direction (+x). The exposed standing body may be the target area 2. The standing body may operate as the popper system.

[0198] Descriptions will be made with reference to FIG. 20(e). After the standing body is completely inserted into the target body, the wire 52 may be connected. The wire 52 may include a first wire 521 drawn from the target body 70, a third wire 523 having one end connected to a waterproof connector connected to the controller 14, and a second wire 522 that connects the third wire 523 to the first wire 521 through a terminal. Here, the second and third wires 522 and 523 may move in the connected state. The first and second wires 521 and 522 may be connected on the site.

[0199] Descriptions will be made with reference to FIG. 20(f). The waterproof connector may be connected to the controller 14.

[0200] Descriptions will be made with reference to FIG. 20(g). The waterproof connector is shown in a state in which it is connected to the controller.

[0201] Descriptions will be made with reference to FIG. 20(h). Thereafter, a heat generation amount and an intensity of infrared rays of the target body may be controlled by operating a control panel 141 of the controller.[Method for Controlling Output of Target]

[0202] The target body needs to generate heat at a set amount of heat (infrared intensity) for a set period of time. These may be said to be basic specifications for use in training and leisure. The inventor may conduct additional research activities to satisfy the specifications. As a result, for example, when using a battery with a capacity of about 30 Ah and about DC 24V, the heat generation amount was controlled, and the temperature was measured by setting and controlling a voltage and current. The results are shown in Table 1. FIG. 21 is a graph illustrating the temperature versus the voltage.TABLE 1Set voltage5.06.07.08.09.010.011.012.013.014.015.016.017.018.019.020.021.022.023.0(V)Current (I)0.50.60.70.80.91.01.11.21.31.41.51.61.71.81.92.02.12.22.3Consumed2.63.75.06.68.310.212.414.717.219.922.825.929.132.536.139.843.948.052.3power (W)Temperature31.232.333.034.135.736.137.040.340.544.345.148.150.353.756.159.460.863.867.0(° C.)

[0203] In the embodiment of FIG. 17, it is necessary to satisfy a usage time of about 300 hours at a minimum of about 2.5 W and about 12 hours at a maximum of about 60 W. Thus, when an external temperature is about 25° C., a target surface temperature is about 37° C., and power consumption is about 15 W, it may be used for about 48 hours.

[0204] In the case of the embodiment of FIG. 18, it is necessary to satisfy a usage time of about 210 hours at a minimum of about 3.5 W and about 9 hours at a maximum of about 80 W. Thus, when the external temperature is about 25° C., the thermal target surface temperature is about 37° C., and the power consumption is about 12 W, it may be used for about 60 hours.

[0205] As described above, the target of the present disclosure may be used for a long time at low costs in an environment in which only the target area is replaced, in the high visibility situation, in an environment in which there is no commercial power supply, in the bad weather, for a period of time requested by the customer, with either the thermal scope or the night vision device, and with the targets having various shapes.

[0206] The present disclosure provides the target having the excellent visibility by arranging the heating body having the predetermined interval in the predetermined shape and defining the inside thereof as the target area.

[0207] The present disclosure may provide the target that exhibits the desired intensity of the infrared radiation (which may depend on the energy to be transmitted) for the desired period of time by controlling the power.

[0208] The present disclosure may provide the target that is capable of easily forming the targets having the various shapes using the heating body.

[0209] The present disclosure may be fabricated inexpensively through the factory production process for commercial purposes, and the expensive portions may be reused except for the shot and damaged portions. Thus, the inexpensive target and the method for fabricating the target may be provided.

[0210] The present disclosure may provide the target that is capable of being used even in the bad weather by processing the portion, to which the electricity is applied, through the sealing.

[0211] In addition, the present disclosure discloses many more effects, which are not disclosed in this article, in individual embodiments. This may also be the effects of the present disclosure.INDUSTRIAL APPLICABILITY

[0212] The invention of the present disclosure may be used as the target. In addition, the target may be expanding into various industries such as military, self-defense, leisure, and sports. Therefore, it has great industrial applicability.

second embodiment

[0126]In addition to the thermal scope, there is a night vision device as a method for identifying a target in dark places. The method for identifying the target in the dark places using the night vision device and the thermal scope is different in terms of its operating principles, possible operating environments, and image characteristics. In terms of the operating principles, the thermal scope detects infrared rays emitted from an object, and the night vision device amplifies and recognizes light reflected from the object. In the environments in which the operation is possible, the thermal scope may operate even in complete darkness, but the night vision device may only operate when there is even little ambient light. In terms of the image characteristics, a color of the thermal scope is black and white colors, but the night vision device is displayed as a green color. Due to the difference in characteristics, the thermal scope has an advantage of being able to identify the objec...

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority under 35 U.S.C. 119 and 35 U.S.C. 365 to Korean Patent Application No. 10-2025-0031203) (filed on Mar. 11, 2025), Korean Patent Application No. 10-2025-0053921 (filed on Apr. 24, 2025), Korean Patent Application No. 10-2025-0133931 (filed on Sep. 17, 2025), and Korean Patent Application No. 10-2025-0157092 (filed on Oct. 27, 2025), which are hereby incorporated by reference in its entirety.BACKGROUND

[0002] The present disclosure relates to a target. The present disclosure relates to a method for fabricating a target.

[0003] Shooting and archery have expanded beyond the use of military to include self-defense, leisure, and sport purposes. A target may be something that is aimed at in shooting or archery. The target is needed not only during the day but also at night. To use the target even at night, an infrared target that radiates heat is provided. The infrared target may be easily detected by a thermal scope. The thermal scope may detect thermal energy (infrared) of an object to create an image, and thus, the thermal scope may detect the target even in complete darkness.

[0004] As inventions for the infrared target, cited inventions 1 (WO2015 / 119353A1; Thermal target board), 2 (US20200232769A1; Highly stable target sleeve identifiable to thermal weapon sights), and 3 (WO2023 / 104857A1; Method and device for reproducing a heat signature) may be exemplified.

[0005] Cited invention 1 provides a heating body at a central portion to narrow a range of infrared radiation. There is a limitation of high cost in providing a wide infrared target.

[0006] Particularly, to provide the heating body, a wire 30, a thread 32, and a heating paint 20 are provided. However, this technology is not realistic in terms of the difficulty of wiring the heating paint and the wires, a fabricating method, and fabricating costs. In addition, there is a limitation that it is not used in rainy weather due to a risk of electric leakage.

[0007] Cited invention 2 provides a thermal film layer 102 at the central portion. The thermal film layer 102 utilizes radiant heat by a film with low emissivity (less than 25% of identification number 102, etc.). Thus, there are limitations with weak infrared radiation and the inability to be used for a long period of time. In detail, energy incident into an object may be reflected, absorbed, or transmitted. Among these, the absorbed energy may be radiated as radiant heat. The radiant heat may be governed by the Stefan-Boltzmann law. Thus, it eventually loses the thermal radiation capacity after a certain period of time. Thus, the target has to be provided with a large energy storage layer. However, it eventually loses the radiation capacity. In addition, there is a limitation that the desired infrared performance is not maintained as a temperature gradually decreases.

[0008] Cited invention 3 uses a laser light source 2 to irradiate an image onto the target. Cited invention 3 allows the image to act as the target. The method may have a notable advantage in that it allows the target to have a specific shape. However, it is excessively difficult to provide a two-dimensional infrared shape of the target with a point light source. This is because it is difficult to transmit energy having a level at which the infrared radiation is emitted from the target. Thus, cited invention 3 may not be realistically applied in real life.SUMMARY

[0067] Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to the drawings. The idea of the present disclosure is not limited to following embodiments. A person skilled in the art who understands the spirit of the present disclosure may easily suggest other embodiments included within the scope of the same spirit by adding, changing, deleting, and adding components. However, this is also included within the scope of the spirit of the present disclosure.

[0068] The present disclosure may include a plurality of embodiments. A first configuration of a first embodiment among the plurality of embodiments may be included by adding or changing a component of another embodiment. The first configuration of the first embodiment among the plurality of embodiments and a second configuration of a second embodiment among the plurality of embodiments may be combined to provide another embodiment that is not specified in the plurality of embodiments.

[0069] In the description of the drawings, regardless of the reference numeral and symbol, identical or similar components are given with identical or similar reference numbers, and redundant descriptions thereof may be omitted.

[0070] The drawings are provided solely to facilitate understanding of the embodiments of the present disclosure, and the technical ideas of the present disclosure are not limited by the attached drawings. It should be understood that all modifications, equivalents or substitutes included within the spirit and technical scope of the present disclosure are included.

[0071] The suffixes “module” and “part” used in the description of the present disclosure for components are given or used interchangeably only for the convenience of writing the specification, and may not have a distinct meaning or role in themselves.

[0072] In describing the embodiments of the present disclosure, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present disclosure.

[0073] In describing the embodiments of the present disclosure, specific examples of the related known technologies may be included in the specification. In this case, the technical connection between the known technology and the present disclosure may be included in the technical idea of the present disclosure.

[0074] In this disclosure, it will be understood that although the ordinal numbers such as first and second are used herein to be described, various elements, these elements should not be limited by these numbers. The terms may be used to distinguish one component from another component.

[0075] It will also be understood that when an element is referred to as being “‘connected to” or “engaged with” another element, it can be directly connected to the other element, or intervening elements can also be present. On the other hand, it will also be understood that when any component is referred to as being ‘directly connected to’ another component, there is no intervening components.

[0076] The terms of a singular form may include plural forms unless referred to the contrary.

[0077] In this disclosure, terms such as “includes” or “has” are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification. Therefore, it does not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0078] In the present disclosure, in the case of a plane (including other surfaces such as a normal plane), it may refer to a surface that may have a certain engineering error rather than a mathematical absolute plane. For example, it may include a certain degree of bending. For example, if it is observed with the naked eye from a certain distance and recognized as the same plane, it may be recognized as a plane. The same is true for other mathematical names. For example, the direction may also include errors within the given engineering range. In the present disclosure, the target may refer to an object that is capable of being used for various purposes to attract attention.

[0079] In the present disclosure, the target may refer to an object as an object to be aimed at. In this disclosure, the direction may be relative to an observer. Therefore, a front side of an object or any direction may mean a direction adjacent to the observer in the object or direction, and a rear side of an object may mean a direction away from the observer in the object or direction.First Embodiment[Configuration of Target]

[0080] FIGS. 1(a) and 1(b) are a plan view and a schematic exploded perspective view, respectively, of a target according to a first embodiment. Descriptions will be made with reference to FIGS. 1(a) and 1(b). The first embodiment may be suitable for long-range targets.

[0081] A target T of the present disclosure may include a recognition area 1. The recognition area may be referred to as a portion that is recognized more prominently than other areas. The recognition area may include an area from which infrared rays are emitted. The recognition area may be placed on a predetermined same plane. The recognition area may radiate the infrared rays in a normal direction of the plane. The radiant heat of the recognition area may be recognized more prominently than other areas by a thermal scope. The recognition area may have a predetermined shape. Here, the shape may include a two-dimensional shape provided on the plane. Here, the shape may be provided by a heating body having a predetermined width, which is changed in its extension direction. Here, an inner area of the shape may provide a target area 2. For this, the heating body may be a planar heating body. The target area 2 may be provided adjacent to the inside of the shape. That is, the target area 2 may be disposed adjacent to the inside of the shape rather than the outside of the shape. Here, the shape may have a geometric center by maintaining a deflated shape. Thus, an observer may intuit that the target is defined at the geometric center of the shape. As a result, according to the target of the present disclosure, visibility of the observer may be greatly improved.

[0082] The target area 2 may be provided by the recognition area 1. The target may be an area that requires close attention and observation. The target area may be an area that is intended to be shot. For example, it could be an area where a bullet or arrow has to be shot. The heating body may be assumed to change an extension direction and to connect a virtual line connecting the heating body to both ends of the heating body. As a result, the inside of the recognition area may provide a two-dimensional inner area that is separated from the outside. Here, the two-dimensional inner area may be the target area. The target area 2 may be provided within the recognition area. A non-target area 3 may be provided outside the recognition area by using the recognition as a boundary.

[0083] The non-target area 3 may be an area that is not target. The non-target area may be an area that occurs incidentally, necessarily, or accidentally to provide the target T. For example, it could be an area on which a bullet or arrow is determined as being missed. The non-target area may not be provided. For example, the recognition area may be heated up to an edge of the target T. In this case, the non-target area is not provided.

[0084] The recognition area, the target area, and the non-target area may be named a recognition module, a target module, and a non-target module, respectively. However, the target T of the present disclosure is primarily viewed from a first direction from the perspective of the observer (including an unmanned aerial vehicle, a camera, and a robot). Thus, each area displayed on the first normal plane is defined to enhance convenience of understanding.

[0085] A relationship between the recognition area, the target area, and the non-target area is clearly explained.

[0086] In the expression of the recognition area, the target area, and the non-target area, the area may mean an area defined on a plane perpendicular to the first direction (e.g., +x axis). The recognition area may be placed on the first normal plane perpendicular to the first direction. The recognition area may extend with a predetermined width. Here, the width may be provided to be more than 10 times greater than a thickness. Here, the width may refer to a thickness direction perpendicular to the extension direction of the recognition area within the first normal plane. Here, the thickness may refer to a thickness of the recognition area in the first direction. The recognition area may have a first portion extending in a second direction within the first normal plane, and a second portion extending in a third direction within the first normal plane. The first portion and the second portion may be continuous. The first portion and the second portion may be in contact with each other. The other end of the first portion and the other end of the second portion may be spaced apart from each other.

[0087] The recognition area 1 may be electrically heated to radiate first light (e.g., infrared rays). Electricity may flow directly into the recognition area. Since the electricity flows directly like this, it is desirable that the recognition area not be shot by bullets. If the bullet shoots the recognition area, it may be judged to have missed. The recognition area may only recognize that the target area is therein.

[0088] The target area may be provided on the inner area of the first normal plane provided as the virtual line connecting both the ends of the recognition area and the recognition area. The virtual line may be provided singly. The recognition area may be one, and the virtual line may also be one. Thus, when the recognition area is the planar heating body 10, it may be provided as a single component. This will be described later. The inner area may be provided on at least one of the first normal plane, which is the same as the first normal plane in the first direction, and the second normal plane, which has a predetermined distance from the first normal plane in the first direction. In other words, the inner area may mean an area that is differentiated from the recognition area in response to observation in the first direction. Even if the first normal plane and the second normal plane have a predetermined gap in the first direction, the gap may be provided to be sufficiently small. As a result, when the observer observes the area in the first direction, the recognition area and the target area may be distinguished. That is, even if the first normal plane and the second normal plane are spaced a predetermined distance from each other in the first direction, when the recognition area and the target area are distinguished in response to observation in the first direction, the first normal plane and the second normal plane may be defined as the same normal plane. In this case, the first normal plane and the second normal plane may be referred to be the same plane in an engineering perspective. In some cases, it may not be the same plane in the engineering perspective. In this case, the embodiment is described separately.

[0089] The target area 2 may be an area on which the bullet has to be shot. The geometric center of the target area may be the most desirable priority target area. The target area may be further provided with a shape that displays the priority target area for each layer. The target area may radiate light (energy) in a form different from the recognition area. The target area may not be provided with a separate structure for infrared radiation. The visible light may be reflected or emitted from the target area.

[0090] The non-target area 3 may be placed outside the target area 2 with the recognition area 1 by using the recognition area 1 as a boundary. The non-target area may be an area on which attention has not to be focused. The non-target area may be an area on which it is not desirable to be shot. The non-target area may be an area that does not have to be shot.

[0091] The target T may include the planar heating body 10. The recognition area 1 may include the planar heating body. The observer may recognize the recognition area 1 by the heat generated by electricity from the planar heating body. The planar heating body has a predetermined thickness in the first direction, but may be provided with a large width, at least twice or more, preferably ten times or more, as the first normal plane. For this reason, it may be said to be a planar (normal plane) heating body. As already explained, the recognition area 1 may extend in the second and third directions from the first normal plane and may have a predetermined width. Thus, the visibility of the recognition area 1 may be provided to the observer. The planar heating body may be provided in a shape having a small upper portion and a large lower portion based on the drawing. For example, the small upper portion may be the head, and the large lower portion may be the torso. The shape that the planar heating body that is capable of being provided on the first normal plane may be various.

[0092] An electrode 10a may be provided at each of both ends of the planar heating body 10. Power may be supplied to the planar heating body through the electrode. The planar heating body may generate heat by the supplied power. The electrode may be made of brass or copper foil. A temperature sensor 16 may be provided adjacent to the electrode. A temperature measured by the temperature sensor 16 may be fed back to a controller 14. The controller 14 may detect the temperature to control the detected temperature to a target temperature. The temperature may correspond to a degree detected by the thermal scope. For example, the higher temperature may be considered to emit stronger infrared radiation, which will stand out in the thermal scope. For example, if the temperature detected by the controller is low, the power may be controlled to increase.

[0093] A protection plate 13 may be provided in front of the first direction from the electrode 10a. The protection plate may have a thickness of at least 10 millimeters or more. The protection plate may prevent the bullet from entering. The protection plate may protect the electrode 10a and its adjacent components. The components of the adjacent portion may include a wire and a connection part. This is because, if the connection wire and the connection part are disconnected, a complete power cut to the planar heating body 10 may occur. The controller 14 may be aligned with the protection plate 13 in the first direction. Thus, the controller 14 may also be protected in the same manner.

[0094] An insulator may be provided adjacent to at least one of a front or rear sides in the first direction of the planar heating body. Each of first and second insulators 11 and 12 may be provided in a shape corresponding to the shape of the planar heating body. At least a portion of the insulator 11 and 12 may be provided in contact with a plane in the first direction of the planar heating body. The insulator may be provided as a non-conductor. The insulator may be provided as at least one layer of non-woven fabric, flame-retardant non-woven fabric, hot melt, and PU hot melt. The planar heating body 10 and the insulators 11 and 12 may be used as a module and may be called a planar heating module 19. The planar heating module 19 may be said to have a structure added to prevent leakage from the planar heating body 10 through which current flows. Here, the current leakage may indicate that an external object is in contact with the wire of the planar heating body.

[0095] The first and second insulators 11 and 12 may be the same or different. The insulator may be provided to be larger than the width of the planar heating body to prevent the external object (e.g., water) from being in contact with the planar heating body. The pair of insulators 11 and 12 may seal inner and outer circumferences of the planar heating body. For this, a surface of the insulator may be provided with an adhesive layer. The adhesive layer may be provided at least on the surface on which pairs 11 and 12 of the insulators that are in contact with each other. The planar heating module 19 may block the external object from being introduced. Thus, the current leakage may be blocked. Here, the current leakage may indicate that water is introduced from outside, and the current leaks along with the water. As described above, the planar heating module 19 may achieve heat generation by external power and isolation from the outside, thereby preventing the current from leaking.

[0096] The planar heating module 19 may be connected to a plate 18. Here, coupling may be an example of attachment. An attachment member 17, which is an adhesive material, may be provided at a contact part between the plate 18 and the planar heating module 19. The attachment member 17 may be, for example, an adhesive tape. The planar heating module may be maintained in its shape on the plate and maintained in its shape against an external load by the attachment member. The plate may maintain a plane having certain rigidity. The plate may also be provided in the form of a predetermined frame. The frame may support the planar heating module. The frame may further include a component for providing the target area having specific target properties. The plate may be made of a resin material having a thickness with predetermined rigidity. The plate 18 may maintain the planar shape of the first normal plane when supported on an upper end. The plate 18 may not be able to maintain its shape when supported on a lower end.

[0097] A product in which the planar heating module 19 and the plate 18 are integrated may be called a target body 70. The target body 70 may be in a state excluding the configurations of the protection plate 13 and the controller 14. The target body 70 may be said to be in a state in which the target body 70 operates as a target by being connected to a power source.[Configuration of Planar Heating Body]

[0098] FIGS. 2(a) and 2(b) are views illustrating a first example and a second example, respectively, of a planar heating body. Descriptions will be made with reference to FIGS. 2(a) and 2(b).

[0099] According to the first example, the heating body may be the planar heating body 10, and the planar heating body may include a woven part 10b. The woven part 10b may be fabric including weft and warp yarns. Here, the warp and the yaw may be exemplified by wires through which electricity flows. The weft and warp yarns may be intertwined with each other. The woven part may extend in one direction. The one direction may refer to extending on a first normal line. The electrode 10a may be provided at both the extending ends of the woven part. The woven part may include a heating module having at least two warp yarns and weft yarns connecting the at least two warp yarns. The woven part may include at least two heating modules. The woven part may be provided with a plurality of weft yarns and a plurality of warp yarns.

[0100] The current may flow through the electrode. Here, the current may pass through the wire providing the woven part 10b to generate heat. The wire may generate ohmic heat due to electrical resistance. The heat-generating energy may be radiated as infrared rays.

[0101] According to the second example, the contents of the first example may be applied. In the second example, an additional woven part 10c may be provided in addition to the woven part 10b. In this case, the woven part 10b may be referred to as a first woven part, and the additional woven part 10c may be referred to as a second woven part. The weft and warp yarns of the second woven part 10c may be added between the weft and warp yarns of the first woven part. The second woven part 10c may be entangled with the first woven part. At least one of the weft or warp yarn of the second woven part may be thicker than at least one of the weft or warp yarn of the first woven part. Specifically, when a thickness of the weft yarn is thick, weaving stability may increase, and durability of the woven part may increase. When the thickness of the warp yarn increases, resistance may decrease, and thus, the heat generation may increase.

[0102] More detailed descriptions of the planar heating body are disclosed in the inventor's published patent KR20170055181A. In addition, various examples of the woven parts 10a and 10b are disclosed in KR20200166194A, which is filed by the inventor of the present disclosure. The technology disclosed in the two cited documents may be included in the present disclosure in terms of the detailed configuration of the planar heating body and connecting the planar heating body to the outside. Alternatively, this does not exclude other various implementation examples.[Configuration of Recognition Area]

[0103] The planar heating body may use metallic wires as the warp and weft yarns. Thus, when compared to fabrics using fine fibers, it was a difficult task to implement a predetermined width on the first normal plane. In other words, the planar heating body could not change the direction. For example, it was difficult to convert the extension in the second direction into the third direction. When forcibly changing the direction, there is a limitation that the wire is disconnected in a tensioned part and is cut in an overlapping portion. It should be noted that the planar heating body is bent inside the first normal plane. To solve this limitation, the inventor thought of folding the planar heating module 19. The inventor did not stop at just thinking about it, but conducted many experiments. Thus, a configuration providing the recognition area 1 was found.

[0104] FIG. 3 is an enlarged view illustrating a bent portion of the planar heating module. In FIG. 3, a shoulder portion of the torso portion is shown in drawing a, a head portion is shown in drawing b, and a lower end of the torso portion is shown in drawing c. Descriptions will be made with reference to FIG. 3.

[0105] The planar heating module needs to be bent while having a certain thickness. For this, the planar heating module 19 may be folded to change a bending angle. Here, the important point is that the bending is done within the first normal plane. Single regular folding of the wire was found to be had good resistant to cutting strength. Here, the folding may mean that top and bottom surfaces of the planar heating module are exchanged. The folding may provide various shapes of the recognition area 1 by varying in angle. Due to the folding, a portion at which the planar heating module overlaps in the first direction occurs.

[0106] In the shoulder portion a of the body, the planar heating module 19 may be bent at a wide angle. In this case, the folding angle of the planar heating module 19 may be greater than about 90 degrees and less than about 180 degrees. In the head portion b, the planar heating module 19 may be bent at a right angle. In this case, the folding angle of the planar heating module 19 may be about 90 degrees. At the lower end c of the body portion, the planar heating module 19 may be bent at a right angle. As described above, various shapes may be generated by changing the folding angle at the folded portion.

[0107] In the folded portion disclosed in FIG. 3, the overlapping portion in the first direction may be laminated into two layers in the first direction by folding the planar heating module 19. Here, the area on which the two layers are laminated may be called a double-layer area. The two-layer area may have a heat generation amount greater than that of the single-layer area. The high heat generation amount may mean that an intensity of the infrared rays is high. The folded portion may be defined by laminating the planar heating module 19 in at least three layers. FIG. 4 is a view illustrating another modified example of the folded portion. Descriptions will be made with reference to FIG. 4.

[0108] The planar heating module 19 may include three portions a, b, and c extending in different directions. Here, the three portions a, b, and c may be provided by folding the planar heating module 19. When the three portions a, b, and c are sufficiently adjacent to each other, the planar heating module 19 may provide the three-layer area 193 on which three layers are laminated in the first direction. The three-layer area 193 may provide a high heat generation amount in the first direction. Thus, the three-layer area may have a heat generation amount greater than that of the two-layer area. It may emit stronger infrared rays. The stronger infrared rays may mean greater visibility. The three-layer area, the two-layer area, and the area on which more layers are laminated may be called a multi-layered area. The multi-layered areas may be provided in various manners as needed. This may be one advantage of the present disclosure.

[0109] When the three portions a, b, and c are sufficiently adjacent to each other, the planar heating modules 19 may provide a shape area d by being adjacent to each other. The area that is not provided by only the width of the planar heating module 19 may be provided through the shape area. The width of the shape area may be greater than the width of the planar heating module 19. Here, the width may mean a straight-line distance connecting the target area to the non-target area within the recognition area 1. For example, a length of a first straight line connecting the target area to the non-target area at any point on the shape area 193 and a second straight line connecting the target area to the non-target area at any point other than the shape area may be compared to each other. At least one of the second straight lines may be longer than the first straight line. The shape area 193 may be provided to provide the target in more diverse shapes.

[0110] Instead of the planar heating module 19 being folded, only the planar heating body 10 may be configured to be folded. In this case, the insulators 11 and 12 may be provided on the top and bottom surfaces in the first direction of the planar heating body 10 having the folded portion. Thus, the current leakage due to the folding may be prevented.

[0111] FIGS. 5(a) and 5(b) are views illustrating an actual wild boar photo and a target fabricated with the planar heating module, respectively, as an example of a target fabricated by folding the planar heating module. Descriptions will be made with reference to FIGS. 5(a) and 5(b).

[0112] To provide the target T, the recognition area 1 may be provided with the planar heating module 19. Here, a plurality of folded portions may occur. The recognition area may extend along a boundary representing the wild boar. The recognition area has a certain thickness. Thus, sufficient visibility may be secured when using a thermal scope. Alternatively, the observer may recognize the recognition area as the wild boar.

[0113] A leg portion of the wild boar may be provided with the multi-layered area to provide the high heat generation amount. The leg portion of the wild boar may be provided with the shape area 193. Thus, the visibility of the wild boar's legs may be improved. The observer may more strongly recognize that a portion presented in a certain shape is the leg portion of the wild boar.

[0114] In the present disclosure, the recognition area may be an area on which a bullet does not have to be shot. Nonetheless, the bullet may shoot the recognition area 1 due to zero adjustment and firing errors. In this case, damage may occur to the planar heating body 10 providing the recognition area. Nonetheless, due to the configuration of the woven parts 10b and 10c, the planar heating body may not be opened. The woven parts may be provided by intersecting and intertwining each other. Thus, even if several warp and weft yarns at a specific portion are disconnected, current may flow through the warp and weft yarns adjacent to the specific portion. Thus, the current may continue to flow. The current may also flow through a portion extending in the extension direction of the planar heating body at the specific portion. Thus, the heating area of the planar heating body may not decrease, and the heating area may be stably maintained.

[0115] In other words, ohm heat may not occur in the specific portion. However, all portions spaced apart from the planar heating body at the specific portion in the extension direction may generate the ohmic heat.

[0116] FIGS. 6(a) and 6(b) are a view illustrating a rear surface of a plate when a recognition area is shot and an image of a thermal scope, respectively. Descriptions will be made with reference to FIGS. 6(a) and 6(b).

[0117] A situation S in which a plurality of bullet holes h occur is compared with a thermal image I in that situation S. Even in the situation S in which the plurality of bullet holes occur, it may be seen that the heat generation of the planar heating body is maintained overall.

[0118] In addition, a range of interest of the thermal image I may be enlarged. In this case, it may be seen that the planar heating body at a position spaced apart from the planar heating body by a predetermined distance in the extension direction of the planar heating body in the bullet hole h also uniformly generates heat in the width direction of the planar heating body.

[0119] Thus, even if the recognition area is shot, the planar heating body may operate until all normal planes at a specific point are cut off. Thus, there is an advantage in that the heating area of the planar heating body does not decrease, and the service life of the target body 70 is extended.

[0120] FIG. 7 is a view targets having various shapes. As illustrated in FIG. 7, the recognition area of the present disclosure may freely produce targets having various shapes. When providing a deer shape, an antler may be made using the shape area d.[Modified Example of End of Recognition Area]

[0121] The recognition area 1 may be provided as a planar heating module19. Both the ends of the recognition area 1 may be adjacent to each other. According to this, a single planar heating module may provide a more perfect shape. If two or more planar heating modules are required, fabricating costs may increase, and a structure may become more complex. The electrodes at the ends of the planar heating module are not in contact with each other. As a result, short circuit of the planar heating body may be prevented. The portions of the planar heating module may overlap each other in the first direction. Thus, a virtual line connecting the end of the planar heating module (which may also be understood as the planar heating body) to the end of the planar heating module (which may also be understood as the planar heating body) may have a modified example. FIG. 8(a) is a view illustrating a case a in which portions of the planar heating module do not overlap each other. FIG. 8(b) is a view illustrating cases b and c in which portions of the planar heating module overlap each other. FIG. 8(c) is view illustrating a case c in which ends of the planar heating module overlap each other as a modified example in which the ends of the planar heating module and a virtual line connecting the ends. Descriptions will be made with reference to FIGS. 8(a)-8(c).

[0122] Referring to FIG. 8(a), the virtual line connecting both the ends of the planar heating module may clearly define a single target area 2. This modification may be preferable to achieve the purpose of preventing the short circuit of the electrodes. This is because the pair of electrodes 10a are spaced apart from each other, and the portions of the planar heating body, which are adjacent to the electrodes, do not overlap each other.

[0123] Referring to FIG. 8(b), the extension parts of the planar heating modules may overlap each other in the first direction. The virtual line connecting both the ends of the planar heating module may be provided on the non-target area 3 or another target area 1. In this case, the original target area may be provided only by the planar heating module. The virtual line connecting both the ends of the planar heating module may provide another target area 1. This modified example may be desirable when responding to various shapes. However, there is a risk of the short circuit occurring if the bullet shoots a spot at which the portions of the planar heating body, which are adjacent to the electrodes, overlap each other.

[0124] Referring to FIG. 8(c), both the ends of the planar heating module may overlap each other in the first direction. In this case, the target area may be provided only with the planar heating module. This modified example may be desirable when responding to a variety of perfect shapes. However, there is a risk of the short circuit occurring if the bullet shoots a spot at which the portions of the planar heating body, which are adjacent to the electrodes, overlap each other. As the overlapping area becomes wider, there may be a limitation that the risk of short circuit increases.

[0125] The modified examples of the end of the recognition area may be selectively applied to each modified example to provide the various shapes of the target.Second Embodiment

[0126] In addition to the thermal scope, there is a night vision device as a method for identifying a target in dark places. The method for identifying the target in the dark places using the night vision device and the thermal scope is different in terms of its operating principles, possible operating environments, and image characteristics. In terms of the operating principles, the thermal scope detects infrared rays emitted from an object, and the night vision device amplifies and recognizes light reflected from the object. In the environments in which the operation is possible, the thermal scope may operate even in complete darkness, but the night vision device may only operate when there is even little ambient light. In terms of the image characteristics, a color of the thermal scope is black and white colors, but the night vision device is displayed as a green color. Due to the difference in characteristics, the thermal scope has an advantage of being able to identify the object even when fog or the like is present, but has a disadvantage of being unable to observe the object such as glass when the thermal scope is present. Although the night vision device have the advantage of being able to accurately identify the object, there is a disadvantage of not being usable in environments with no light.

[0127] The second embodiment presents an embodiment of a target that is suitable as the target for the night vision device. In the second embodiment, the configuration of the target of the first embodiment may be applied. For example, [Configuration of target], [Configuration of planar heating body], [Configuration of recognition area], and [Modified example of end of recognition area] may be the same as or similar to those of the first embodiment.

[0128] FIG. 9 is an image of the thermal scope as an experimental screen for explaining characteristics of a second embodiment. Descriptions will be made with reference to FIG. 9.

[0129] A portion a is a portion at which a metal plate with high reflectivity and low emissivity is placed, and a portion b is a portion at which a heating plate is placed. The metal plate may be placed on the heating plate. In an image acquired using the thermal scope, the portion a appears dark, and the portion b appears bright. This may mean that the portion a has a low temperature, and the portion b has a high temperature. Likewise, when using the metal plate with the low emissivity, even if the temperature is high, the temperature may appear low by the thermal scope that detects infrared rays. When the metal plate is used on the target area 2, heat may be transferred from the recognition area 1 to the target area. However, even if the target area is heated, visual differentiation from the recognition area may increase in the image of the thermal scope. The metal plate to the target area 2 may be applied to obtain greater visibility for the boundary between the recognition area and the target area when using the thermal scope.

[0130] A plate to which aluminum is applied may be used as the metal plate. The aluminum may be expected to have great applications due to its low emissivity (about 0.03 to about 0.08), ease of processing, low costs, and light weight. The aluminum may be used in the form of aluminum being deposited on a resin film.

[0131] FIG. 10 is a view illustrating a left side that illustrates a front view of the target of the second embodiment and a right side that illustrates an image I of the thermal scope as the target according to the second embodiment. Descriptions will be made with reference to FIG. 10.

[0132] The recognition area 1 may be provided with the planar heating module. The target area 2 may be provided within the recognition area. A metal plate may be provided on the plate 18 of the target area 2. The plate 18 may be coated with a metal thin film. The plate 18 may be coated with aluminum. At least a portion of the plate 18 may be exposed in a first direction (+x) without being covered by the recognition area 1. The metal plate material may be provided on a portion of the plate 18, which is exposed in the first direction (+x). The plate may reflect second light incident into the first direction (+x) in a fourth direction (−x). The plate may be a reflection plate. Here, the reflection plate may only act on the target area. The second light may be different light from the first light. The second light may include visible light.

[0133] The plate (using the metal plate) 18 has a plurality of holes h caused by shooting of the bullets. An image of the thermal scope clearly shows the holes h caused by the shooting of the bullets. This is because the thermal scope detects the infrared rays from the background after passing through the holes h. In most cases, the background may be adjacent to the target. As described above, when the target area 2 is the metal plate, a position to which the bullet is shot on the target area 2 may be accurately known. Thus, the shot position may be accurately determined. This is because, due to the low emissivity of the metal plate, it emits the infrared rays more prominently than the recognition area 1 and the background.

[0134] The target T may be observed with the night vision device. The plate may be observed with the night vision device. In this case, the metal plate (target area) may be observed more prominently than other adjacent areas (recognition area and non-target area). This is because the metal plate has high reflectivity. Non-woven fabric may be provided as the insulator 11 providing the recognition area 1. The non-woven fabric may be made of a black color material. In the recognition area 1, any black color material may be used for the externally exposed portion. In this case, the visual differentiation between the target area and the recognition area may be greatly enhanced. The reflectivity of the nonwoven fabric is lower than that of the metal plate. Thus, the target area 2 may be visually recognized more prominently than the recognition area 1.

[0135] In the second embodiment, the plate having high reflectivity and low emissivity was used on the target area. Thus, when observing the target with the thermal scope, the target area may be detected to have a lower temperature than an actual temperature, and thus, the visibility may be excellent. This is because the emissivity of the plate is low. When observing the target with a night vision device, reflected light of the target area may be greatly amplified, and thus, visibility may be excellent. This is because the reflectivity of the plate is high. According to the second embodiment, there is an advantage in that the target is used in any environment. Here, the environment may include an environment in which there is no light, and night vision device is not used, an environment in which there is an obstacle in a path of light, and the thermal scope is not used, and an environment in which the target is far away or small, and thus, the visibility of the recognition area is poor.Third Embodiment

[0136] The target may be used in various environments. Examples include long-range and close-range targets, and fixed and portable types. The third embodiment presents an embodiment suitable for use as a close-range target and portable. In the third embodiment, the configuration of the targets of the first and second embodiments may be applied. The third embodiment will be explained focusing on differences from other embodiments. For example, [Configuration of target], [Configuration of planar heating body], [Configuration of recognition area], and [Modified example of end of recognition area] may be the same as or similar to those of the first and second embodiments.

[0137] FIGS. 11(a), 11(b), and 11(c) are a front perspective view, a side view, and a rear perspective view, respectively, of a target according to a third embodiment. Descriptions will be made with reference to FIGS. 11(a), 11(b), and 11(c).

[0138] A predetermined board 20 is provided on a rear surface or at a rear side of a target body 70. The rear surface and the rear side may be a back or rear side of the plate 18 that is not visible to an observer. The board may be a rigid member having enough rigidity to maintain its shape and stand upright. The board 20 may be provided as a component of the plate 18. Here, it may be said that the component is integrated and thus does not need to be separated. The board 20 may use a material having a predetermined thickness, such as cork, to ensure convenience in processability and rigidity. The board 20 may use a plate-shaped material having a predetermined thickness, which is made of cork. The board 20 may be a cork board.

[0139] The recognition area 1 and the target area 2 may be provided on a front side of the board 20. The third embodiment may not provide a non-target area 3. A planar heating module 19 may be provided on the recognition area 1.

[0140] The target body 70 may maintain a shape of the target regardless of which a portion is held by using the board 20. That is, it is possible to maintain a posture perpendicular to the first direction seen by an observer. This may be a difference from the first and second embodiments. As an example, a protection plate 13 and a controller 14 may be provided at the front and rear sides of the target body 70, respectively. The protection plate 13 and the controller 14 may support the front and rear sides of the target body 70. Thus, the target body 70 may be erected. As an example, the protection plate 13 and the controller 14 are aligned in the first direction at a lower center of the target body 70. This is to prevent the target from being distorted in its posture when being shot. If the firm posture fixation is possible, the protection plate 13 and the controller 14 may be placed at any edge of the target body 70. Even if the target body 70 is shot, the bullet may easily break and penetrate the board. The target body 70 may be maintained in its upright state. The target body may be used as a target for multiple shootings.

[0141] The target of the third embodiment may be maintained in the upright state by itself. A size of the target may be provided to be carried to be approximately 30*20 centimeters in a first normal direction. The target has an advantage of being portable and ready for use after being mounted as needed.Third-1 Embodiment

[0142] The plate 18 may provide the target area 2. The planar heating module 19 may provide the recognition area 1. This is clear through the first to third embodiments. In addition, the plate 18 and the planar heating module 19 may be disposed together on the first normal plane. This is because there is no practical difference from an engineering perspective. The third-1 embodiment presents a case in which the target area and the recognition area are not considered to be on the same plane in the engineering perspective. In the third-1 embodiment, the configuration of the target of the third embodiment may be applied. This explains a differences between the third-1 embodiment and the third embodiment.

[0143] FIG. 12 is a side cross-sectional view of the target according to the third-1 embodiment. Descriptions will be made with reference to FIG. 12.

[0144] The planar heating module 19 is provided on a front surface of the board 20. The plate 18 is provided on a rear surface of the board 20. A portion of the board 20 corresponding to the plate 18 may be cut. The recognition area 1 and the target area 2 may be spaced apart by a distance equal to the thickness of the board.

[0145] In this case, it may not be said from the engineering standpoint that the recognition area 1 and the target area 2 are on the same plane. However, the target area 2 is placed on an inner area of the recognition area 1, and thus, the target area may be easily identified. This is because, as a result of the observer observing in the first direction, the target area 2 is recognized as being disposed on the inner area of the recognition area 1. In other words, when the observer observes the target in the first direction, both the recognition area 1 and the target area 2 may be placed on the first normal plane. The target of the present disclosure may have a configuration in which the target area 2 is disposed on the inner area of the recognition area 1 in response to the observer observing in the first direction. The results are the same in this embodiment.

[0146] The target body 70 may be upright by a supporter 31. The supporter 31 may be provided in a groove, and the target body 70 may be fitted into the groove. The supporter 31 may include a protection plate and a controller. The protection plate and the controller may be coupled to each other to provide the supporter 31.Fourth Embodiment

[0147] The plate 18 may correspond to the target area 2, and the planar heating module 19 may correspond to the recognition area 1. As a result, the plate is a frequently discarded item that is shot by a bullet, and the planar heating module 19 is a non-shot item. The planar heating module is an expensive item compared to the plate. The inventor studied a technology that enables the planar heating module to be used for a long period of time. As a result, the inventor arrived at the fourth embodiment. The fourth embodiment presents an embodiment in which the planar heating module is used repeatedly. In the fourth embodiment, the configurations of all the embodiments may be applied. A specific example is explained by exemplifying the third-1 embodiment.

[0148] FIG. 13 is a perspective view of the target according to the fourth embodiment. Descriptions will be made with reference to FIG. 13.

[0149] The plate 18 and the board 20 may be provided as separate components. That is, the board is not a component of the plate and is different from that of the third embodiment.

[0150] The plate and the board may be separate components for a separate target. In this case, the plate 18 may be referred to as a first plate, and the board 20 may be referred to as a second plate. That is, the two components can cooperate to perform a function of the plate 18. The first plate 18 may provide a target area, and the second plate (i.e., board) 20 may maintain a shape and form of the recognition area (including the planar heating body) 1. The description in this paragraph may also be applied to other embodiments in which the roles of the plate 18 are separated.

[0151] Fasteners 181 and 182 that are easy to be coupled and separated (free enough to be removed by the hand) may be provided on a surface on which the plate and the board face each other. The fastener may include a surface fastener (e.g., Velcro 181 and 182 (registered trademark), adhesive, etc.), a hook, and a screw. The first plate 18 may be coupled to the second plate 20 by the fastener.

[0152] When the target area 2 is cut off, and the use thereof is terminated, the plate may be removed and discarded, and a new plate may be attached. Thus, the planar heating module may be used repeatedly. As a result, a product may be used for a long time.

[0153] An embodiment in which the fastener is applied is possible even when the board 20 is not present. For example, the planar heating module 19 may perform the role of the board. For example, the fastener may be attached to the rear surface of the planar heating module and the front surface of the plate.Fifth Embodiment

[0154] The target may be used in various environments. For example, the target may be used in rainy and high-humidity environments. Since the planar heating module 19 conducts electricity, there is a great need for sealing. The target requires a production of large quantities of the same product. The fifth embodiment proposes a target that satisfies universal usability and mass production. In the fifth embodiment, the configurations of the targets of the first to fourth embodiments may be applied. The fifth embodiment will be explained focusing on the differences from other embodiments.

[0155] FIG. 14 is a plan view of the target according to the fifth embodiment. Descriptions will be made with reference to FIG. 14.

[0156] The target may be said to be a plate-shaped member extending along a first normal line. The plate 18 is placed at a center of the target as the target area 2. The planar heating module 19 is placed on the periphery of the target as the recognition area 10. Inner and outer circumferences of the planar heating module 19 may be sealed. Both surfaces of the planar heating module 19 may be sealed. A wire 52 may be drawn out between the sealed surfaces. The wire 52 may be connected to an electrode 10a of the planar heating body 10. The plate 18 may be coupled to any surface of the planar heating module 19. The planar heating module 19 and the plate 18 coupled to each other to provide the target body 70.

[0157] In the planar heating module 19, a width of the planar heating body 10 may be smaller than a width of each of the insulators 11 and 12. Inner surfaces of the insulators 11 and 12 may be coupled to each other with the planar heating body therebetween. The pair of insulators have a first portion that is not in contact with each other due to the intervention of the planar heating body. The pair of insulators have a second portion that is in contact with each other without the intervention of the planar heating body. The second portion may be coated with an adhesive. The second portion may be coated with an adhesive. The planar heating module may be sealed by the second portion. An adhesive or adhesion agent may also be applied to the first portion. Thus, the planar heating body may be firmly fixed.

[0158] The target, particularly the target body 70 used for the target, may be fabricated through a mass production process. The target may be prevented from leaking.

[0159] FIGS. 15(a)-15(g) are views for explaining a process of fabricating a target body. Processes shown in FIGS. 15(a) to 15(f) may be sequentially performed. Descriptions will be made with reference to FIGS. 15(a)-15(g).

[0160] Descriptions will be made with reference to the process (a). The planar heating module 19 may be provided folded into a predetermined shape on one surface of a protective film 11a. The protective film 11a may be provided as a component of the insulator 11. The protective film 11a may be a PU film. Any one layer of the protective film may include a material layer having high emissivity. Any one layer of the protective film may include a base layer. Any one layer of the protective film may include an adhesive layer. An adhesive or adhesion agent may be applied to an attachment layer.

[0161] A temporary assembly tool 51 may be coupled to a folded portion of the planar heating module 19. Here, the planar heating module 19 may include an insulating layer such as non-woven fabric and may exclude the protective film 11a. The temporary assembly tool 51 may be exemplified by a tape. The temporary assembly tool 51 may be pressed against the folded portion so as to be in close contact with the protective film 11a. The temporary assembly tool 51 may prevent the folded planar heating module 19 from being unfolded. This may prevent defects from occurring in the subsequent pressing process. The temporary assembly tool 51 may be provided at all places at which the planar heating module is folded.

[0162] Descriptions will be made with reference to the process (b). The wire 52 may be connected to the electrode 10a. The place at which the electrode 10a and the wire 52 are connected may be coupled to the temporary assembly tool 51. The temporary assembly tool 51 may allow the electrode 10a and the wire 52 to be in close contact with the protective film 11a. This may prevent defects from occurring in the subsequent pressing process.

[0163] Descriptions will be made with reference to the process (c). Another protective film 12a is covered on a top surface of the temporary assembly tool 51. The protective film 11a and another protective film 12a may be the same product. The protective film 11a and another protective film 12a may be attached to each other while placing other components therein. For this, the adhesive or adhesion agent may be applied between the protective film 11a and another protective film 12a.

[0164] Descriptions will be made with reference to the process (d). Thereafter, the planar heating module 19 may be sealed by pressing the protective film 11a and another protective film 12a. The pressing process may use a press that applies a pressure and heat. With the planar heating body 10 placed at a center, both the inside and outside of the planar heating body 10 may be sealed. A process (e) shows an intermediate body that has completed the process to date. In this state, intrusion or damage by an external object may be prevented. In the state of the intermediate body, long-distance movement and transportation may be possible.

[0165] Descriptions will be made with reference to the process (f). Thereafter, an inner area of the planar heating module 19 may be cut off. The target area 2 may be provided later on the cut-off area. A recognition area 1 may be provided outside the target area 2.

[0166] Descriptions will be made with reference to the process (g). The attachment member 17 may be attached to any surface of the recognition area 1 in the intermediate body. The attachment member may be a double-sided tape. The double-sided tape may have adhesive properties on both surfaces. Any one surface of the attachment member 17 may be attached to the recognition area 1. Thereafter, after removing a release paper on the other surface of the attachment member, the plate 18 may be attached.

[0167] When the process is completed, the target body 70 of FIG. 14 may be provided.Sixth Embodiment

[0168] The target of the present disclosure may be used as a portable short-range target. In this case, the purpose may be to protect the controller, facilitate the assembly, and maintain the vertical direction with respect to the first direction. For example, a process of connecting the protection plate 13, the target body 70, and the controller 14 of the third embodiment is required. The sixth embodiment is described by citing the third embodiment, but is not limited thereto, and the configuration of the targets of the first to fifth embodiments may be applied.

[0169] FIG. 16 is a view for explaining a process of fabricating the target according to the sixth embodiment. Descriptions will be made with reference to FIG. 16.

[0170] The target body 70 may be placed at the center, and also, the protection plate 13 may be placed on the front surface (+x side), and the controller 14 may be placed on the rear surface (−x side). Any edge of the target body may be placed between the protection plate and the controller. A screw may be fastened from a rear side of the controller 14 toward a front side (+x direction). The screw may fasten all the controller, the target body, and the protection plate. The protection plate and the controller may have the same or similar height. Thus, each of the protection plate and the controller may become a supporter 31. For fastening the screw, a recess 61 may be provided in the protection plate 13. For fastening the screw, a recess 62 may be provided in the controller 14.

[0171] The controller 14 may be provided with a connection terminal 64 to which the wire 52 is connected. The connection terminal 64 may be provided with a button and a hole. The hole may be opened with the button, the wire 52 may be inserted into the hole, and the button may be closed. With this operation, the connection between the connecting terminal and the wire may be completed. Disconnecting the connection terminal from the wire may be performed in an opposite operation.

[0172] The controller 14 may be provided with a battery mounting part 65. The battery may provide required power by using a plurality of commercially available AA or AAA batteries.

[0173] A power switch 63 may be provided in the controller 14. The power switch may control heat generation (which may include an amount of heat generated) of the planar heating body through an on / off operation. When the connection is completed, and the power switch is turned on, an operation of the target may be initiated. The operation of the target may include sustaining a predetermined amount of heat. Alternatively, the initiation of the target operation may include a heating operation of the planar heating module.

[0174] According to this embodiment, the controller may be safely protected by the protection plate. According to this embodiment, the components may be brought in a separated state and simply assembled and used on the site. According to this embodiment, since the commercial battery is used, the power not only may be conveniently supplied anywhere, but the battery may also be conveniently replaced and used. According to this embodiment, an upright state may be well maintained. According to this embodiment, the screw may be separated to conveniently replace the component.Seventh Embodiment

[0175] The present disclosure provides an embodiment in which characteristics of the target area are changed. In the second embodiment, the target capable of responding to both the thermal scope and the night vision device is presented. An output of the recognition area may be adjusted to correspond to specifications or operations of the thermal scope. It is not easy to cope with the specifications or operations of the night vision device. In the fourth embodiment, the Velcro is suggested, but this may be limited to short-range and targets. This embodiment proposes an embodiment in which the target area varies in response to the night vision device. Any explanation insufficient in the description of this embodiment may be applied as is to the description of the first to sixth embodiments.

[0176] FIGS. 17 and 18 are views illustrating the target according to the seventh embodiment. In FIG. 17, the target may have both a head and a torso. In FIG. 18, the target may have a head and chest. This will be described with reference to FIGS. 17 and 18.

[0177] The target body 70 may be provided in a pocket shape with an opened front surface. The planar heating module 19 and the plate 18 may have at least a portion of an outer circumference having the same shape. The outer circumferences of the planar heating module 19 and the plate 18 may be provided with the same shape. The outer circumferences of the planar heating module 19 and the plate 18 may be coupled to each other. Some portions of the outer circumferences of the planar heating module 19 and the plate 18 may not be coupled to each other. A portion of each of the outer circumference of the planar heating module 19 and the plate 18, which is not coupled, may provide an opening hole 71. The opening hole 71 may be provided at a lower end with respect to the direction of gravity. As described above, in the state in which the portions of the outer circumferences of the planar heating module 19 and the plate 18 are coupled to each other, a remaining outer portion may be coupled, and thus, the planar heating module 19 and the plate 18 may provide the pocket shape. The pocket shape may mean that an external object enters and exits through the opening hole 71.

[0178] The planar heating module 19 may correspond to the recognition area 1. The inner area of the recognition area 1 may be opened. Through the opened inner area, the plate 18 may be observed in the first direction. The plate 18 may be the target area. Any portion of the plates 18 may overlap the planar heating module 19 in the first direction. The overlapping portion may not function as the target area. It may be seen that any portion of the plates 18 do not become the target area 2. Another portion of the plates 18 may not overlap the planar heating module 19 in the first direction. At least another portion of the plates 18 may correspond to the target area 2. The plate 18 may correspond to the target area 2. An external area of the recognition area 1 may correspond to a non-target area 3. In the target of this embodiment, in response to observation in the first direction, the target area 2 may be provided on an inner area of the recognition area 1. In other words, the recognition area and the target area may not be placed on the same plane strictly. Nonetheless, in response to observation in the first direction, the recognition area, the target area and the non-target area may be placed together on the first normal plane.

[0179] The target body 70 may be connected to the controller 14 by a wire 52. Power consumption may vary depending on a size and specifications of the target body. The wire 52 may have a predetermined length (e.g., about 6 meters). The wire may include a sealed waterproof connector.

[0180] The controller 14 may include a temperature controller. The controller 14 may include a battery. A heating state of the planar heating module 19 may be controlled according to a control of the controller.

[0181] A standing body for supporting the target body 70 may be inserted into the opening hole 71. Here, the standing body may not obstruct the plate 18 from being observed in the first direction. For example, an observer may recognize the plate 18 as the target area 2. In this case, the plate 18 may be a first plate (see the fourth embodiment). In this case, a standing body may only function as a second plate (see the fourth embodiment).

[0182] The standing body (e.g., see reference numeral 81 of FIGS. 20(a)-20(h)) that has the target area 2 may be inserted into the opening hole 71. The standing body may have a wide surface corresponding to a size of the opening hole 71. The standing body may be supported on the ground or on a wall. In the standing body, a portion inserted into the opening hole 71 may provide the target area 2. The target area may use materials having various reflectivities. A variety of materials including wood, ceramic, plastic, and a metal may be used. Various materials may be used as the metal, including aluminum, copper, iron, and stainless steel. Thus, the target may be used in various forms to suit an operational state of the night vision device.

[0183] Even without the standing body, the target body 70 of this embodiment may be used as the target. For example, it may be used by fixing the periphery.

[0184] FIG. 19 is a cross-sectional view of an adjacent position of the opening hole, which is taken along an extension direction of the opening hole. That is, FIG. 19 is a cross-sectional view taken along line 19-19′. Descriptions will be made with reference to FIG. 19.

[0185] The plate 18 of the target body 70 of the seventh embodiment may use a waterproof material. The waterproof material may be waterproof cloth made of cloth. The waterproof cloth may have predetermined reflectivity. The waterproof cloth may provide the target area 2. The waterproofing cloth may block water introduced from a rear side. Thus, the target may be used even in bad weather.

[0186] As described, an inner portion of the recognition area 1 provided by the planar heating module 19 may be opened. Through the opened portion, the waterproof cloth (the waterproof cloth may be the plate 18) may be exposed forward in the first direction. A connection part between the plate 18 and the planar heating module 19 may be maintained airtight. Outer circumferential portions of the plate 18 and the planar heating module 19 may be connected to each other. Waterproof fabric may be used at the connection part between the two members. The fabric may use narrow-width fabric 75. The narrow-width fabric may be further treated with water-repellent and water-pressure resistant processing to enhance waterproofing effects. Thus, water may not be introduced through the connection part between the two members. Thus, the target may be used even in bad weather.

[0187] Waterproof resins 11c and 12c may be further used as components of the insulating layers 11 and 12. For example, the resin may be made of thermoplastic polyurethane (TPU). The waterproof material resin may prevent water from being introduced.

[0188] An adhesive or sealing material may be further added between surfaces on which the plate 18 and the planar heating module 19 are in contact with each other. Thus, leakage current from the planar heating body 10 may not occur.

[0189] The contact points of the plate 18 and the planar heating module 19 may be spaced apart from each other. Thus, the opening hole 71 may be provided. A member providing the target area 2 may be inserted and withdrawn through the opening hole. According to this embodiment, the target area of the target body may actively vary in response to the night vision device. According to this embodiment, the target body may be used even in bad weather.Eighth Embodiment

[0190] The present disclosure provides embodiments that are capable of improving the above-described sense of shooting. In the seventh embodiment, a member that generates striking sound may be used as the standing body that is inserted into and removed from the opening hole 71. Thus, when a bullet hits the target area, the fact of the shooting may be detected by the sound. Any explanation insufficient in the description of this embodiment may be applied as is to the description of the seventh embodiment.[Method for Coupling Target]

[0191] FIGS. 20(a)-20(h) illustrate how to use the target according to this embodiment. The processes in FIGS. 20(a) to 20(h) are sequentially performed. Descriptions will be made with reference to FIGS. 20(a)-20(h).

[0192] First, the standing body 81 will be described. A rigid plate may be used as a material for the standing body 81. The rigid plate may be provided by using a metal plate. The metal plate may be provided with a protrusion 82 that amplifies impact sound when being shot. The standing body may have a rigid plate having the same shape as an outer circumference of the target body 70 in the first direction. An outer circumference of the standing body may be slightly smaller than that of the target body 70. This is to ensure that the standing body is inserted. The standing body may be inserted into the pocket-shaped target body 70. The target body 70 may be upright by the standing body 81. The standing body may be likened to a person, and the target body may be likened to clothing.

[0193] The standing body 81 may provide first and second plates (see the fourth embodiment). The standing body 81 may provide functions of the first plate and the second plate together. In this case, the target body 70 may also provide a first plate. In other words, the plate (here, waterproof cloth) 18 of the target body 70 may provide the first plate that provides the target area 2. However, the standing body 81 may be shielded after being coupled. In other words, the plate 18 may be observed by an observer in the first direction and recognized as the target area. Depending on the usage aspect (i.e., a state in which the standing body is inserted into the opening hole), the plate 18 may be shielded in the first direction by the standing body 81. In this case, the standing body 81 may provide the target area. In this case, the standing body 81 may provide functions of the first plate and the second plate together.

[0194] The standing body 81 may operate as a portion of a popper system. The popper system may be said to be a system that has a function of falling when a bullet is shot. The standing body may make sound when shot and fall over. Here, the standing body 81 may include the rigid plate inserted into the target body 70.

[0195] Descriptions will be made with reference to FIG. 20(a). The standing body 81 is inserted through the opening hole 71 of the target body 70. The inserted portion of the standing body may include the rigid plate. When observed in the first direction, the standing body and the target body may have the same shape. The standing body may be slightly smaller in size than the target body.

[0196] Descriptions will be made with reference to FIG. 20(d). The standing body may be smoothly inserted into the inside of the target body due to the difference in size of the target body.

[0197] Descriptions will be made with reference to FIGS. 20(c) and 20(d). When the standing body is completely inserted, a portion of the standing body 81 may be exposed in the first direction (+x). The exposed standing body may be the target area 2. The standing body may operate as the popper system.

[0198] Descriptions will be made with reference to FIG. 20(e). After the standing body is completely inserted into the target body, the wire 52 may be connected. The wire 52 may include a first wire 521 drawn from the target body 70, a third wire 523 having one end connected to a waterproof connector connected to the controller 14, and a second wire 522 that connects the third wire 523 to the first wire 521 through a terminal. Here, the second and third wires 522 and 523 may move in the connected state. The first and second wires 521 and 522 may be connected on the site.

[0199] Descriptions will be made with reference to FIG. 20(f). The waterproof connector may be connected to the controller 14.

[0200] Descriptions will be made with reference to FIG. 20(g). The waterproof connector is shown in a state in which it is connected to the controller.

[0201] Descriptions will be made with reference to FIG. 20(h). Thereafter, a heat generation amount and an intensity of infrared rays of the target body may be controlled by operating a control panel 141 of the controller.[Method for Controlling Output of Target]

[0202] The target body needs to generate heat at a set amount of heat (infrared intensity) for a set period of time. These may be said to be basic specifications for use in training and leisure. The inventor may conduct additional research activities to satisfy the specifications. As a result, for example, when using a battery with a capacity of about 30 Ah and about DC 24V, the heat generation amount was controlled, and the temperature was measured by setting and controlling a voltage and current. The results are shown in Table 1. FIG. 21 is a graph illustrating the temperature versus the voltage.TABLE 1Set voltage5.06.07.08.09.010.011.012.013.014.015.016.017.018.019.020.021.022.023.0(V)Current (I)0.50.60.70.80.91.01.11.21.31.41.51.61.71.81.92.02.12.22.3Consumed2.63.75.06.68.310.212.414.717.219.922.825.929.132.536.139.843.948.052.3power (W)Temperature31.232.333.034.135.736.137.040.340.544.345.148.150.353.756.159.460.863.867.0(° C.)

[0203] In the embodiment of FIG. 17, it is necessary to satisfy a usage time of about 300 hours at a minimum of about 2.5 W and about 12 hours at a maximum of about 60 W. Thus, when an external temperature is about 25° C., a target surface temperature is about 37° C., and power consumption is about 15 W, it may be used for about 48 hours.

[0204] In the case of the embodiment of FIG. 18, it is necessary to satisfy a usage time of about 210 hours at a minimum of about 3.5 W and about 9 hours at a maximum of about 80 W. Thus, when the external temperature is about 25° C., the thermal target surface temperature is about 37° C., and the power consumption is about 12 W, it may be used for about 60 hours.

[0205] As described above, the target of the present disclosure may be used for a long time at low costs in an environment in which only the target area is replaced, in the high visibility situation, in an environment in which there is no commercial power supply, in the bad weather, for a period of time requested by the customer, with either the thermal scope or the night vision device, and with the targets having various shapes.

[0206] The present disclosure provides the target having the excellent visibility by arranging the heating body having the predetermined interval in the predetermined shape and defining the inside thereof as the target area.

[0207] The present disclosure may provide the target that exhibits the desired intensity of the infrared radiation (which may depend on the energy to be transmitted) for the desired period of time by controlling the power.

[0208] The present disclosure may provide the target that is capable of easily forming the targets having the various shapes using the heating body.

[0209] The present disclosure may be fabricated inexpensively through the factory production process for commercial purposes, and the expensive portions may be reused except for the shot and damaged portions. Thus, the inexpensive target and the method for fabricating the target may be provided.

[0210] The present disclosure may provide the target that is capable of being used even in the bad weather by processing the portion, to which the electricity is applied, through the sealing.

[0211] In addition, the present disclosure discloses many more effects, which are not disclosed in this article, in individual embodiments. This may also be the effects of the present disclosure.INDUSTRIAL APPLICABILITY

[0212] The invention of the present disclosure may be used as the target. In addition, the target may be expanding into various industries such as military, self-defense, leisure, and sports. Therefore, it has great industrial applicability.
