Description

Technology Field

[0001] The present invention relates to a safety sign device, and more specifically, to a safety sign device configured to prevent human and property damage caused by secondary collisions by enabling the driver to display a danger sign to a rear vehicle more quickly, easily, and safely when a vehicle accident occurs on the road. Background Technology

[0002] When vehicle accidents occur on expressways, motorways, etc., the incidence of secondary collisions caused by driver negligence—such as rear-end collisions where a rear vehicle fails to notice an accident vehicle ahead and collisions with a vehicle temporarily stopped on the shoulder of the road—is increasing every year, and consequently, the scale of human casualties and material damage is increasing.

[0003] In order to convey a dangerous situation or emergency stop status of the vehicle to vehicles behind, the driver must flash the hazard lights. In particular, when stopping the vehicle on a road or shoulder to check for vehicle abnormalities or breakdowns that occur while driving, the Road Traffic Act mandates that a safety triangle be installed at a distance of 100 to 200 meters behind the vehicle along with the hazard lights.

[0004] These safety triangles, regulated by relevant laws, are manufactured to be easily identifiable through light reflected from vehicle headlights not only during the day but also at night; recently, the installation of light-emitting diodes or light sources on safety triangles is continuously increasing visibility and visibility even at night through the emitted light.

[0005] However, there is a problem in that it takes a considerable amount of time for a driver, who is somewhat distracted due to a traffic accident or vehicle breakdown, to find and assemble the safety triangle from the vehicle. Additionally, moving 100 to 200 meters behind the vehicle while carrying the safety triangle causes significant psychological anxiety and fear. Furthermore, moving behind the vehicle to set up the safety triangle is very dangerous in environments such as highways where vehicles behind are traveling at high speeds, and in reality, secondary accidents involving collisions with vehicles behind frequently occur while the driver is moving to set up the safety triangle, especially during nighttime travel.

[0006] Therefore, in order to overcome the problems and limitations of existing vehicle accident indication methods / devices such as safety triangles, a new type of safety sign device configured to prevent human and property damage caused by secondary collisions by enabling drivers to indicate danger signs to rear vehicles more quickly, easily, and safely when a vehicle accident occurs on the road is gradually increasing in the industry.

These terms are used merely to distinguish the component from other components, and the essence, order, or sequence of the component is not limited by such terms.

[0034] A safety sign device (100) according to one embodiment of the present invention is characterized by being configured to allow a driver to display a danger sign to a rear vehicle more quickly, easily, and safely when a vehicle accident occurs on a road, thereby minimizing or preventing damage to human life and property caused by a secondary collision accident. A perspective view of the safety sign device (100) according to the present invention is shown in FIG. 1a, and a front view, rear view, and side view of the safety sign device (100) according to the present invention are respectively shown in FIG. 1b, and a rendering image of the safety sign device (100) according to the present invention is exemplarily shown in FIG. 1c.

[0035] As described, the safety sign device (100) according to the present invention may be implemented in a cylindrical or cylinder type that is formed by extending in the longitudinal direction and has a cross-section that is circular or substantially circular, and for example, the safety sign device (100) according to the present invention may be implemented in a shape similar to a tumbler.

[0036] In addition, the safety sign device (100) according to the present invention may be configured to improve ease of carrying and handling by the user in the event of a dangerous / emergency situation on the road by being implemented with a width of about 70 mm and a height of about 200 mm, however, these product dimensions are merely exemplary dimensions for easy understanding of the present invention, and it will be obvious that the safety sign device (100) according to the present invention may be implemented and manufactured with other different dimensions.

[0037] The vehicle driver can store the safety sign device (100) as shown in FIG. 1 in the trunk, glove box, etc., and in case of an emergency on the road, take out the safety sign device (100) and attach it to the rear window, ceiling, etc. of the vehicle or attach it to the rear of the vehicle with a clip for use.

[0038] As illustrated, the safety sign device (100) according to the present invention may be largely composed of an upper body (110), a lower body (120), a detachable unit (130), a string unit (140), etc. As the upper body (110), the lower body (120), and the detachable unit (130) are vertically combined, a predetermined height (e.g., about 200 mm) of the safety sign device (100) may be defined, and the height of the upper body (110) may be implemented to be almost the same as the combined height of the lower body (120) and the detachable unit (130).

[0039] For reference, the more detailed configuration of the upper body (110), lower body (120), detachable unit (130), and string unit (140) constituting the safety sign device (100) according to the present invention will be described more specifically through FIGS. 2 and 3 below.

[0040] As described above, on the outer surface of each component constituting the safety sign device (100) according to the present invention, a number indicating the order of use of the device, a method of use of the device, and precautions for the device may be expressed in numbers, text, and / or graphs. In this way, intuitive and direct guidance is additionally expressed on the outer surface of the safety sign device (100) and provided to the user, thereby enabling the driver to utilize the safety sign device (100) according to the present invention without difficulty when a dangerous or emergency situation occurs on the road, thereby minimizing human and property damage caused by a secondary collision.

[0041] For example, when an emergency / crisis occurs on the road, the sequence in which a driver uses the safety sign device (100) according to the present invention may be displayed as a predetermined number in each associated area of ​​the safety sign device (100). As described below, the safety sign device (100) according to the present invention is configured to indicate danger to a rear vehicle by attaching it to the rear window of the vehicle, the ceiling of the vehicle, etc., by suction using a suction plate (131, see FIG. 2), or by attaching it to a part of the rear area of ​​the vehicle using a clip. To do this, a series of procedures must be performed, such as attaching the device to the vehicle, removing the main cover (111, see FIG. 2), pressing a button (122, see FIG. 2) to inflate the airbag (112, see FIG. 2), and attaching the hook (143) to the vehicle. This sequence of device usage may be displayed on the outer surface of the safety sign device (100) as number types such as ①, ②, ③, ④, etc.

[0042] For example, as shown in FIG. 1c, the number ① may be displayed in a part of the detachable unit (130), more specifically in the front area of ​​the detachable unit (130), and may be placed adjacent to guidance or explanatory text such as “Please press to attach and then turn,” so that the user can intuitively recognize that the first action in the event of a danger / emergency on the road is to press the detachable unit (130), which is placed at the bottom of the safety sign device (100), onto the rear window of a vehicle, etc., and then rotate it in a predetermined direction.

[0043] Likewise, the number ② is displayed on the inner side of the triangle facing upward on the front of the main cover (111), so that the user can intuitively recognize the removal operation of the main cover (111) as a second step, and the number ③ is displayed on the inner side of the triangle facing downward on the front of the control cover (121, see FIG. 2), so that the user can intuitively recognize the action of pressing the button (122) as a third step.

[0044] FIG. 2 is an exploded perspective view of a safety sign device (100) according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2 together, the safety sign device (100) according to the present invention has an upper body (110), a lower body (120), and a detachable unit (130) sequentially arranged and combined from top to bottom, and a string unit (140) may be additionally combined to at least a portion of the lower body (120).

[0045] The upper body (110) may be positioned on the upper part of the safety sign device (100) according to the present invention, and more specifically may be coupled and positioned on the upper part of the lower body (120) to be described later, and may be implemented as a cylindrical type with a circular cross-section or substantially circular cross-section. As illustrated, the upper body (110) according to the present invention may include a main cover (111), an airbag support (113), a wing (114), a wing support (115), a fan cover (116), a fan (117), etc., and although not illustrated in FIG. 2, an airbag (112, see FIG. 4) may be accommodated in a folded state in the internal space of the upper body (110).

[0046] The main cover (111) may be configured to cover the outer side of the upper body (110) according to the present invention, and considering that it is configured to protect the internal parts of the upper body (110) under normal circumstances and is removed from the upper body (110) for use in dangerous / emergency situations, the main cover (111) may be referred to by other terms such as a lid. For reference, the main cover (111) according to the present invention may be manufactured from ABS (Acrylonitrile Butadiene Styrene) resin, but is not necessarily limited to this material.

[0047] For example, the main cover (111) according to the present invention may be provided in a cylindrical shape with an empty interior and a closed upper surface while the lower surface is open, and its cross-section may be circular or substantially circular, and accordingly, an airbag (112), an airbag support (113), a wing (114), a wing support (115), a fan cover (116), a fan (117), etc. provided and arranged in the internal space by the main cover (111) can be effectively protected from external impact.

[0048] As described below through FIG. 4, in order to display a danger / emergency situation on the road to drivers of vehicles behind using the safety sign device (100) according to the present invention, it is necessary to remove the main cover (111) after attaching the safety sign device (100) to the vehicle glass, etc. using a detachable unit (130) (e.g., see FIG. 4 (b) and (c)). To this end, the main cover (111) according to the present invention is configured to cover the internal elements of the upper body (110) from the outside, and accordingly, the user can more easily remove the main cover (111) in an emergency situation.

[0049] Additionally, as illustrated in FIG. 1c, a product name / designation such as 'SAFE accident notification sign' may be displayed on the front of the main cover (111) according to the present invention, and the visibility of the product name / designation may be further improved by making the text color (e.g., red, etc.) of the displayed product name / designation distinctly different from the color (e.g., white, etc.) of the main cover (111).

[0050] In addition, a predetermined number may be additionally written inside an upward triangular arrow on the front of the main cover (111) according to the present invention, for example, the number “2” may be placed and displayed inside the upward triangle, and accordingly, the user (or driver) can intuitively recognize that the operation of lifting the main cover (111) upward and removing it from the upper body (110) must be performed as a second procedure for installing and operating the safety sign device (100) according to the present invention.

[0051] In addition, although not shown in the drawings, a method of use introducing the procedure and process of using the safety sign device (100) may be displayed in a graphic type on the rear surface of the main cover (111) according to the present invention. Thus, by familiarizing the driver with the installation / utilization method of the safety sign device (100) according to the present invention through the guidance on the method of use displayed on the rear surface of the main cover (111) in normal times, the driver can be guided to respond quickly in the event of an emergency on the road.

[0052] In this regard, situations requiring the safety sign device (100) according to the present invention, such as vehicle accidents or breakdowns, are mostly situations where drivers are psychologically anxious, confused, and unable to concentrate, so there may be a problem where the main cover (111) according to the present invention is lost or damaged after being removed from the upper body (110). To prevent such problems, although not explicitly shown in the drawings, the main cover (111) according to the present invention may be additionally configured to be connected to another area of ​​the safety sign device (100), for example, at least a part of the lower body (120), and the main cover (111) may be connected to the outside of the control cover (121) using, for example, a string or cord, and accordingly, the problem of the main cover (111) being lost or damaged can be effectively prevented even if the main cover (111) is urgently removed from the upper body (110) in an emergency situation.

[0053] Additionally, in FIG. 1c, the main cover (111) is made of an opaque material so that its internal components, such as the internal airbag support (113), wing (114), wing support (115), and fan cover (116), are not visually visible from the outside before the main cover (111) is removed. However, according to another embodiment of the present invention, the main cover (111) may be made of a transparent or semi-transparent material so that its internal components are visually visible from the outside.

[0054] The airbag (112) can be accommodated in a folded state within the internal space of the upper body (110) according to the present invention, preferably supported by an airbag support member (113), and can be configured to inject air by a fan (117) whose operation is activated by the pressure of a button (122) when necessary. More specifically, as illustrated exemplarily in FIGS. 4, FIGS. 6, etc., the airbag (112) according to the present invention can be configured to have a circular shape, that is, a round shape, when air is injected, and a triangular mark, such as a safety triangle, can be printed on its front surface, and the triangular mark can be implemented to have a color that has the best visibility in contrast to the color of the airbag (112). For reference, considering that the airbag (112) according to the present invention is configured to change into an inflated state by injecting air through the operation of the fan (117), the airbag (112) may be referred to by other terms such as a balloon.

[0055] For example, if the airbag (112) is implemented in white, the triangular sign displayed on the front of the airbag (112) can be implemented in red, or if the airbag (112) is implemented in yellow, the triangular sign displayed on the front of the airbag (112) can be implemented in black, and accordingly, the visibility of the safety sign device (100) according to the present invention can be further improved.

[0056] Additionally, the airbag (112) according to the present invention may be implemented in a fluorescent color, and the safety sign displayed on the front may be coated with a retroreflective material, thereby further improving the visibility of the safety sign on the front of the safety sign device (100), more specifically the safety sign on the front of the airbag (112).

[0057] In addition, the airbag (112) according to the present invention can be manufactured from a waterproof, rainproof, and windproof material so that the safety sign displayed on the front of the airbag (112) can be clearly seen visually without shape change or deformation even in rainy or snowy environments and in windy environments. Accordingly, the airbag (112) is not damaged or deformed by rain even when there is heavy rain, thereby maintaining the usability and reliability of the safety sign device (100) according to the present invention at a certain level. For reference, the airbag (112) according to the present invention can be manufactured from PET, nylon, etc., and the airbag support (113) can be manufactured from ABS resin, but is not necessarily limited to these materials.

[0058] For reference, the following drawings illustrate an airbag (112) that expands into a circular shape upon air injection, but this is merely an example for easy understanding of the present invention, and the shape of the airbag (112) that expands by air injection through the operation of the fan (117) can be implemented in various ways, such as a triangle or a square. However, the inventors have conducted various experiments and tests regarding the shape of the airbag (112) and its visibility, and have confirmed that a circular airbag (112) has the best visibility.

[0059] The wing (114) can be configured to hold the airbag (112) with air injected into it from below when air is injected into the airbag (112) according to the present invention. When the safety sign device (100) according to the present invention is attached to the rear window of a vehicle, etc., and the main cover (111) is removed, and the user presses the button (122) of the lower body (120), the air injection operation of the fan (117) is activated, and air is injected into the airbag (112), causing the airbag (112) to take on a circular shape. However, if the wind blows relatively strongly on the road, etc., a problem may occur where the airbag (112) shakes left and right or back and forth due to the wind.

[0060] To prevent such problems, the upper body (110) according to the present invention may additionally be provided with a wing (114) configured to hold an air-injected airbag (112) from the lower side, and the wing (114) may be supported by a wing support member (115). More specifically, as shown in FIG. 2, a coupling protrusion may be formed on the lower part of the wing (114), and a groove configured to receive the coupling protrusion of the wing (114) may be formed in the upper edge area of ​​the wing support member (115), and the coupling of the wing (114) to the wing support member (115) may be realized by inserting and coupling the coupling protrusion of the wing (114) into the groove of the wing support member (115).

[0061] Accordingly, when the airbag (112) is not inflated and is contained inside, the wing (114) is coupled and supported to the wing support (115) and is positioned on the outside of the airbag support (113) in a manner substantially parallel to the airbag support (113). When a dangerous or emergency situation occurs on the road and the airbag (112) is inflated by air injection, the wing (114) unfolds outwardly to stably hold the lower part of the airbag (112) (e.g., see FIG. 6 (a)). To this end, the height of the wing (114) according to the present invention can be implemented to be higher than the height of the airbag support (113).

[0062] Additionally, the wings (114) according to the present invention may be provided in multiple numbers, and for example, as shown in FIG. 6 (a), they may be provided with four wings (114) to hold the airbag (112) filled with air from below, thereby supporting the airbag (112) to maintain its shape and position stably without shaking even in external environments such as wind. For reference, the wings (114) and wing support (115) according to the present invention may be manufactured from ABS resin, but are not necessarily limited to this material.

[0063] As illustrated, a plurality of protrusions may be formed on the outer circumference of the bottom surface of the wing support member (115) according to the present invention, and correspondingly, a plurality of grooves may be formed on the outer circumference of the upper surface of the fan cover (116), and the combination of the wing support member (115) and the fan cover (116) can be effectively realized by inserting the plurality of protrusions formed on the wing support member (115) into the plurality of grooves formed on the fan cover (116).

[0064] A fan (117) may be configured to inject air into an airbag (112). As illustrated, the fan (117) according to the present invention may be protected from external impacts, etc. by having its surroundings covered by a fan cover (116), and the module of the fan (117) and the fan cover (116) may be coupled to the lower side of the wing support (115) and to the upper side of the lower body (120).

[0065] Additionally, the present invention is characterized in that when a button (122) is pressed by a user during a dangerous / emergency situation on the road, the fan (117) according to the present invention is configured to inject air into the airbag (112) as its operation is activated under the control of a controller (not shown). It is more desirable for the airbag (112) to continuously maintain a state where it is filled with air as much as possible so that the triangular safety mark displayed on the front of the airbag (112) can be clearly and distinctly seen by drivers of vehicles behind it. To this end, the fan (117) according to the present invention may be implemented as a high-speed turbo fan, a blower fan, etc. For reference, the fan cover (116) according to the present invention may be manufactured from ABS resin, but is not necessarily limited to this material.

[0066] Here, on the front of the fan cover (116) according to the present invention, instructions regarding precautions that the user must take when using the safety sign device (100) may be written, and as exemplarily described in FIG. 6 (a), instructions such as ‘Please check if the airbag is properly secured, please evacuate to a safe place after installation, please replace the battery after one use, please store after completely drying after use’ may be written.

[0067] Additionally, although not explicitly shown in the drawing, the number '4' indicating the operation sequence of the device may be displayed on the rear of the fan cover (116) according to the present invention, inside the downward arrow, and through this, the driver can be made to recognize, by authority, that the string unit (140) provided at the bottom of the safety sign device (100) should be attached to the vehicle, for example, the trunk, rear door, etc., on the vehicle body fitting line after the air inflation of the airbag (112) is completed as described later through Fig. 4.

[0068] Additionally, although not explicitly shown in the drawing, a plurality of grooves may be formed on the outer circumference of the upper surface of the fan cover (116), and a plurality of protrusions formed on the outer circumference of the lower surface of the wing support (115) may be inserted and coupled into these plurality of grooves, and accordingly, the coupling of the wing support (115) and the fan cover (116) may be realized.

[0069] The lower body (120) may be positioned below the upper body (110). More specifically, the lower body (120) according to the present invention may be positioned between the upper body (110) and the detachable unit (130).

[0070] Additionally, the lower body (120) according to the present invention may be implemented as a cylindrical (cylinder) type with a cross-section that is circular or substantially circular, just like the upper body (110), and the length of the lower body (120) may be shorter or have a height that is nearly the same as the length of the upper body (110). As shown in FIG. 2, the lower body (120) according to the present invention may include a control cover (121), a button (122), etc.

[0071] The control cover (121) may be implemented as a hollow cylindrical body defining a predetermined internal space. Components, parts, etc., such as a controller (not shown), a motor (not shown), and a battery (not shown) may be placed in the internal space defined by the control cover (121). In particular, the controller (not shown) may be electrically and / or electronically connected to a button (122) provided on the front of the control cover (121) to control the on / off operation of the fan (117) in response to a user pressing the button (122). For reference, the control cover (121) according to the present invention may be manufactured from ABS resin, but is not necessarily limited to this material.

[0072] An upper protrusion (121b) may be formed on the upper part of the control cover (121), and this upper protrusion (121b) may be implemented as a protruding type having a smaller cross-sectional area compared to the cross-sectional area of ​​the control cover (121), and accordingly, when the lower body (120) according to the present invention is coupled to the upper body (110), the coupling of the upper body (110) and the lower body (120) may be implemented with a predetermined spacing between the upper body (110) and the lower body (120) rather than being coupled in contact without a gap (for example, see FIG. 1a and FIG. 1c).

[0073] Additionally, although not explicitly shown in the drawing, a protrusion may be formed in the center of the upper protrusion (121b) according to the present invention, and this protrusion may be inserted into a hole formed in the center of the bottom surface of the fan (117), and the connection between the lower body (120) and the upper body (110) may be realized by inserting the protrusion formed in the center of the upper protrusion (121b) of the control cover (121) into the hole in the center of the bottom surface of the fan (117).

[0074] As previously described, a fan (117), the outside of which is covered by a fan cover (116), may be disposed at the lower part of the upper body (110) according to the present invention. In order to operate the fan (117) to inject air into the airbag (112), the inflow of external air is required, and external air for injecting air into the airbag (112) can be effectively inflowed through this gap provided between the upper body (110) and the lower body (120).

[0075] Additionally, a button (122) configured to activate the air injection operation of the fan (117) may be provided on the front of the control cover (121) according to the present invention, and a number ('3') indicating the operation sequence of the device may be displayed on the upper part of the button (122) along with a downward arrow. As described in FIG. 4 below, when a dangerous / emergency situation occurs on the road, the driver attaches the safety sign device (100) to the rear window of the vehicle, etc., removes the main cover (111), and then presses the button (122) to inject air into the airbag (112). By displaying the sequence number '3' on the upper part of the button (122) inside the downward arrow, the driver can intuitively recognize that they must perform the operation of pressing the button (122).

[0076] The button (122) according to the present invention may be made of a material such as silicone or rubber, and when a user presses the button (122), the fan (117) is activated so that air is injected into the airbag (112), and thereafter, when the user presses the button (122) again at the end of a dangerous / emergency situation on the road, the fan (117) is deactivated so that the injection of air into the airbag (112) is stopped, and the airbag (112) can return to its original non-inflated state.

[0077] Additionally, a ring attachment portion (121a, see FIG. 3) may be additionally formed on the rear surface of the control cover (121) according to the present invention. As described below, a string unit (140) configured to interconnect the safety sign device (100) and the vehicle may be provided to prevent loss due to detachment of the safety sign device (100) according to the present invention, and a ring (142) provided at one end of the string unit (140) may be attached to the ring attachment portion (121a) provided on the rear surface of the control cover (121).

[0078] The detachable unit (130) may be positioned and coupled to the lower part of the lower body (120) and configured to be detachably coupled to at least a portion of the vehicle. When a danger / emergency situation occurs on the road, the safety sign device (100) according to the present invention is attached to the vehicle to inject air into the airbag (112), thereby providing a certain danger sign visually to drivers of rear vehicles. The attachment of the safety sign device (100) to the vehicle, for example, the detachable coupling, may be implemented by the detachable unit (130) according to the present invention.

[0079] Additionally, the detachable unit (130) according to the present invention is characterized by being hinge-connected to the lower body (120) at the lower part of the lower body (120), and in particular, is configured to be hinge-connected with the upper rear surface of the detachable unit (130) and the front rear surface of the lower body (120) as an axis, and accordingly, it is possible to adjust the angle of the lower body (120) relative to the detachable unit (130) based on the hinge.

[0080] When the safety sign device (100) according to the present invention is attached to the rear window of a vehicle, the suction plate (131) of the detachable unit (130) may be attached to the rear window of the vehicle having a predetermined incline. In this case, it is preferable that the airbag (112) be positioned vertically to the ground so that the airbag (112) can be seen most clearly and more certainly by the drivers of the vehicle behind. To achieve this, the unit of the lower body (120) and the upper body (110) can be angle-adjusted vertically to the ground by using the hinge connection of the lower body (120) to the detachable unit (130) (for example, refer to the device state diagram of FIGS. 4 and FIGS. 6). For reference, according to another embodiment of the present invention, the angle adjustment (or joint adjustment) of the safety sign device (100) may be implemented in a different way based on the hinge connection between the upper body (110) and the lower body (120), which will be described in more detail in FIGS. 5 below.

[0081] Here, the detachable unit (130) according to the present invention may be implemented based on an adsorption method using a suction plate (131) or a clip coupling method using a clip, and in the drawings below, the adsorption method using a suction plate (131) is shown as a representative example. As shown, the detachable unit (130) according to the present invention may be composed of a suction plate (131), a suction lever (132), a lever cover (133), etc.

[0082] The adsorption plate (131) can be configured to adsorb to an adsorption surface, such as a vehicle rear window, a vehicle ceiling, etc., and through the adsorption implemented by the adsorption plate (131), the safety sign device (100) according to the present invention can be more stably attached to the vehicle rear window, etc.

[0083] Although a certain degree of attachment effect can be achieved by attaching the suction plate (131) to the rear window of a vehicle or the like and having the driver press it slightly downward, a suction lever (132) configured to rotate in a predetermined direction on the outer circumference of the suction plate (131) may be additionally provided to further improve the degree of attachment, and the suction lever (132) may be covered by a lever cover (133) at its upper end.

[0084] That is, when a user attaches the suction plate (131) to the rear window of a vehicle, etc. and then rotates the suction lever (132) in a predetermined direction, for example, by rotating the suction lever (132) about 90° or more in a predetermined direction, the air between the suction plate (131) and the rear window of the vehicle is further compressed, thereby strengthening the suction force of the suction plate (131), and accordingly, the safety sign device (100) according to the present invention can be more firmly and stably fixedly attached to the rear window of a vehicle, etc., even in a windy road environment.

[0085] In order to provide auxiliary guidance to the user on this procedure, a specific guidance phrase, such as “Please press to attach and then rotate,” may be displayed on the front of the suction lever (132) according to the present invention along with a specific sequence number (e.g., refer to the product image in FIG. 1c), thereby allowing the driver to more intuitively recognize the action to be taken in the event of a dangerous or emergency situation on the road. Additionally, a lever handle (132a) is provided on a portion of the circumference of the suction lever (132) and protrudes outward by a specific length, thereby assisting the user in gripping and rotating the suction lever (132) more easily. For reference, the suction plate (131), suction lever (132), and lever cover (133) according to the present invention may be manufactured from ABS resin, but are not necessarily limited to this material.

[0086] As illustrated in FIG. 2, the method of attaching a safety sign device (100) to a vehicle's rear window, vehicle ceiling, etc., by means of a detachable unit (130) composed of a suction plate (131), a suction lever (132), a lever cover (133), etc., by means of suction, however, there is a problem in that the suction and attachment of the device cannot be reliably guaranteed due to a large amount of moisture present on the window or ceiling in environments with heavy rainfall. To this end, the detachable unit (130) according to another embodiment of the present invention may generally implement a physical attachment (e.g., interlocking) with the vehicle by means of a clip while the vehicle trunk is open, and in some cases, the detachable unit (130) according to the present invention may be equipped with both a suction plate (131) and a clip so that one of the methods can be selectively utilized according to the user's choice or preference.

[0087] A string unit (140) may be configured such that one end is connected to a part of the lower body (120) and the other end is connected to a part of the vehicle. When the detachable unit (130) is implemented as a suction-type unit based on a suction plate (131), the suction force decreases, and if the safety sign device (100) detaches from the rear window of the vehicle, a problem may occur in which the safety sign device (100) is lost or damaged. To prevent such problems in advance, the safety sign device (100) according to the present invention may additionally be equipped with a string unit (140). Considering these attributes, the string unit (140) according to the present invention may be referred to by other terms such as a safety auxiliary string, and an exemplary diagram for explaining the configuration, connection, and function of the string unit (140) according to the present invention is shown in FIG. 3. As shown, the string unit (140) according to the present invention may be composed of a combination of a string (141), a loop (142), a hook (143), etc.

[0088] The string (141) may constitute the basic body of the string unit (140) according to the present invention and may be implemented as a webbing ribbon made of, for example, fabric. Additionally, a fixing tension cord may be additionally provided in a part of the string (141), thereby allowing the user to utilize the string unit (140) while freely adjusting the length of the string (141) as needed. For example, the string (141) according to the present invention may be implemented to be usable with a maximum length of approximately 1200 mm.

[0089] A ring (142) may be provided at one end of the string (141), and the ring (142) may be configured to be attached or coupled to a ring attachment part (121a) provided at the rear of the control cover (121), for example, the ring (142) may be made of a plastic ring.

[0090] Additionally, a hook (143) may be provided at the other end of the string (141), and this hook (143) may be configured to be fitted into a fitting line such as the trunk or rear door of the vehicle. Accordingly, even if the suction force of the suction plate (131) on the rear window of the vehicle is weakened and the safety sign device (100) is detached from the vehicle, the loss or prevention of the safety sign device (100) according to the present invention can be effectively prevented through the secondary connection between the hook (143) and the vehicle.

[0091] Here, although not explicitly shown in the drawings, the safety sign device (100) according to the present invention may further include additional components, elements, etc., such as a controller, a battery, a light-emitting means, etc.

[0092] A controller (not shown) may be configured to comprehensively control the operation, function, etc. of the safety sign device (100) according to the present invention, and may be implemented, for example, in the form of a chip mounted on a printed circuit board (PCB) in the internal space of the lower body (120). For example, the controller (not shown) may be configured to inflate the airbag (112) by activating the air injection operation of the fan (117) in response to the detection of pressure applied to the button (122), and may be configured to stop the air injection into the airbag (112) by deactivating the air injection operation of the fan (117) in response to the detection of pressure applied to the button (122) once again.

[0093] A battery (not shown) may be configured to supply power to various components and elements constituting the safety sign device (100) according to the present invention, for example, a controller (not shown), a fan (117), a motor (not shown), etc. The battery (not shown) may be placed in the internal space of the safety sign device (100), for example, in the internal space of the lower body (120), and more preferably may be configured to have a capacity to supply power for a sufficient time (e.g., about 30 minutes) to express a danger / emergency situation on the road and subsequently process it (e.g., two 9V batteries), and by providing guidance to replace the battery (not shown) after one use as indicated on the back of the fan cover (116), the problem of the safety sign device (100) being unable to be used due to a lack of battery when necessary can be prevented in advance.

[0094] A light-emitting means (not shown) may be configured to emit a predetermined light in the direction of an air-inflated airbag (112), and may be additionally provided in the inner space of, for example, an airbag support (113), and may receive power for lighting from a battery (not shown). In order to further improve the visibility of the safety sign device (100) according to the present invention to a rear vehicle driver, particularly at night, a light-emitting means (not shown) configured to emit light in the direction of the airbag (112) may be additionally provided so that it can be seen more clearly and visually prominently to a rear vehicle driver. For example, the light-emitting means (not shown) may include a plurality of high-brightness LEDs, but is not necessarily limited thereto.

[0095] For example, the ON / OFF of the light-emitting means (not shown) can be configured to be synchronized with the air inflation operation of the airbag (112), so that the light-emitting means (not shown) is kept in the OFF state during normal times, and can be configured so that when a user presses the button (122) to inflate the airbag (112) in response to a danger / emergency situation on the road, the light-emitting means (not shown), for example, an LED, is switched to the ON state at the same time.

[0096] In producing a lighting effect by a light-emitting means (not shown), light of a predetermined color is provided in the direction of the airbag (112), and at the same time, the light-emitting means (not shown) according to an additional embodiment of the present invention may be configured to additionally implement a blinking effect, that is, a flashing effect, and accordingly, additional measures may be taken so that drivers of rear vehicles can more clearly recognize the danger / safety sign displayed on the front of the airbag (112).

[0097] Here, the light color implemented by the light-emitting means (not shown) may be implemented as a constant color (e.g., red, etc.), but according to an additional embodiment of the present invention, the light color of the light-emitting means (not shown) may be configured to change according to the lighting time to further enhance visibility. For example, when the safety sign device (100) according to the present invention is used during the day, the light color of the light-emitting means (not shown) may be implemented as the color with the best visibility during the day, and similarly, when the safety sign device (100) is used at night, the light color of the light-emitting means (not shown) may be implemented as the color with the best visibility at night, and in determining / implementing the light color of the light-emitting means (not shown) with the best visibility, the color of the airbag (112) may be additionally considered.

[0098] FIG. 4 is an illustrative diagram for explaining the sequence or process of use of a safety sign device (100) according to an embodiment of the present invention when an emergency situation occurs on a road.

[0099] First, when a dangerous or emergency situation occurs on the road, the driver can take out the safety sign device (100) from the trunk, glove box, etc. and attach it to the rear window of the vehicle (see FIG. 4 (a)). At this time, as described above, the suction power of the suction plate (131) can be further improved by rotating the suction lever (132) of the detachable unit (130) according to the present invention in a predetermined direction, or the safety sign device (100) can be attached to the rear area of ​​the vehicle using a clip method instead of the suction method based on the suction plate (131).

[0100] When the attachment of the safety sign device (100) to the rear window of a vehicle is completed, the angle of the safety sign device (100) can be adjusted based on the hinge connection of the lower body (120) and the detachable unit (130) according to the present invention (see Fig. 4(b)). Typically, since the rear window of a vehicle is implemented at an angle, when the safety sign device (100) is attached to the surface of the window, the airbag (112) is also positioned at an angle toward the ground, causing a problem in which the driver of the vehicle behind cannot properly recognize the airbag (112). Therefore, by adjusting the angle of the combined lower body (120) and the upper body (110), measures can be taken to position the airbag (112) as vertically as possible toward the ground.

[0101] Here, angle adjustment for a portion of the safety sign device (100) based on a hinge connection (or based on an joint structure) may be manually implemented by a user (or driver), or the safety sign device (100) may be configured so that such angle adjustment is automatically implemented under the control of a controller (not shown). In the latter case, for example, the safety sign device (100) according to the present invention may additionally be provided with an actuator (not shown) mechanically coupled to a hinge provided between the lower body (120) and the detachable unit (130), and accordingly, when the user presses the button (122), the fan (117) is activated to implement the air inflation operation of the airbag (112), and at the same time, the actuator (not shown) is also activated to rotate the lower body (120) to form a predetermined angle with the detachable unit (130), thereby enabling the airbag (112) to be positioned as vertically as possible to the ground.

[0102] When the angle adjustment of the lower body (120) is implemented, the user (driver) can remove the main cover (111) of the upper body (110) to prepare for the inflation of the airbag (112) by air injection (see (c) of FIG. 4). At this time, as previously mentioned, the main cover (111) can be additionally connected to other areas such as the lower body (120) through a strap, string, etc. to prevent the loss of the main cover (111) according to the present invention.

[0103] After the main cover (111) is removed, the user can inflate the airbag (112) by pressing the button (122) provided on the front of the lower body (120), for example, by pressing the button (122) (see (d) of FIG. 4), and as a result, the airbag (112) with a predetermined safety sign or danger sign displayed on the front can be switched to an inflated state (see (e) of FIG. 4).

[0104] Afterward, by attaching the hook (143) of the string unit (140) according to the present invention to a body fitting line such as a trunk or rear door (see (f) in FIG. 4), the loss or damage caused by the release of suction of the safety sign device (100) that may occur can be effectively prevented. For reference, the operation of attaching the string unit (140) to a part of the vehicle may be performed between the operation of the user removing the main cover (111) and the operation of the user pressing the button (122).

[0105] FIG. 5 is a conceptual diagram illustrating a hinge-coupled body angle adjustment and a forward air injection method according to an additional embodiment of the present invention.

[0106] FIGS. 1 to 4 illustrate / describe a configuration in which the lower body (120) is hinge-connected to the detachable unit (130), and accordingly, the combination of the lower body (120) and the upper body (110) is angle-adjusted with respect to the detachable unit (130), thereby enabling air injection into the airbag (112). Thus, the airbag (112) can be inflated by injecting air upward by means of a fan (117), that is, the air injection operation into the airbag (112) can be implemented based on an upward air blowing method.

[0107] Regarding the method of injecting air into such an airbag (112), the inventors have conducted various experiments and confirmed that if air is injected from the rear to the front by a fan (117) as shown in FIG. 5, air injection into the airbag (112) can be implemented more stably.

[0108] To this end, as shown in FIG. 5(a), the upper body (110) and the lower body (120) according to the present invention may be configured to be hinge-connected, and based on the hinge connection, the upper body (110) may be implemented to be angle-adjustable relative to the lower body (120), and accordingly, as shown in FIG. 5(b), air may be injected from the rear to the front by a fan (117), thereby inflating the airbag (112), that is, the air injection operation for the airbag (112) may be implemented based on a forward air blowing method.

[0109] In implementing the safety sign device (100) according to the present invention, only an upward air injection method may be made possible by implementing a hinge connection only between the lower body (120) and the detachable unit (130), or only a forward air injection method may be made possible by implementing a hinge connection only between the upper body (110) and the lower body (120). However, according to an additional embodiment of the present invention, by implementing a hinge connection between both the lower body (120) and the detachable unit (130) and between the upper body (110) and the lower body (120), the upward air injection method or the forward air injection method may be selectively utilized as desired by the user, or according to the vehicle environment or the type of accident, and accordingly, both user convenience and user individuality in using the safety sign device (100) according to the present invention can be further enhanced.

[0110] As described above, the relative angle adjustment of the body can be configured to be automatically adjusted based on an actuator (not shown). To this end, an actuator (not shown) may be additionally mechanically connected to a hinge implemented between the upper body (110) and the lower body (120). Additionally, at least a portion of the safety sign device (100) may be additionally provided with a mode setting means (not shown) that allows the user to pre-set an upward air injection mode and a forward air injection mode.

[0111] Accordingly, when a dangerous / emergency situation occurs on the road, the driver attaches the safety sign device (100) to the rear window of the vehicle, etc., removes the main cover (111), and then presses the button (122). The controller (not shown) checks the pre-set upward air injection mode or forward air injection mode, and if it is set to the upward air injection mode, the joint structure of the device is implemented as shown in FIG. 4, and if it is set to the forward air injection mode, the joint structure of the device is implemented as shown in FIG. 5 (b), thereby reducing the effort required by the user to directly deform the joint structure of the body and adjust the angle.

[0112] FIG. 6 is an illustrative diagram for explaining the use of a safety sign device (100) according to one embodiment of the present invention.

[0113] As the safety sign device (100) according to the present invention is attached to the rear window of a vehicle and the angle is adjusted so that the airbag (112) can be positioned as vertically as possible to the ground based on the hinge connection between the lower body (120) and the detachable unit (130) (see FIG. 6 (a)), it can provide improved and enhanced visibility to drivers of vehicles behind.

[0114] In addition, the safety sign device (100) according to the present invention can additionally transmit a certain amount of light to the airbag (112) through a light-emitting means such as an LED additionally provided therein, and accordingly, by maintaining a high degree of visibility consistently even during the day as shown in FIG. 6 (b) and at night as shown in FIG. 6 (c), it can effectively minimize secondary accidents on the road by delivering a more certain forward danger perception effect to drivers of rear vehicles.

[0115] For reference, since the safety sign device (100) according to the present invention is configured to be reusable, when the danger / emergency situation is completely ended, the user can return to the vehicle and press the button (122) to stop the air injection of the airbag (112), fold the airbag (112) with the air completely removed, and place it in the space between the airbag support members (113), and more preferably, by replacing the battery with a new battery, the problem of the device becoming unusable due to a lack of battery during future use can be prevented in advance.

[0116] At this time, a folding method for reusing the airbag (112) may be additionally provided to the user through a predetermined instruction manual, and such instruction manual may be provided together with the safety sign device (100) as a type of output document or may be additionally written on the outer surface of the safety sign device (100).

[0118] As described above, according to one embodiment of the present invention, a safety sign device allows a vehicle driver who has experienced an accident, breakdown, etc., to indicate a dangerous situation more quickly and easily on the road.

[0119] In addition, according to one embodiment of the present invention, a vehicle driver who has experienced an accident, breakdown, etc., can more safely indicate a dangerous situation.

[0120] In addition, according to one embodiment of the present invention, the safety sign device can further improve visibility by implementing angle adjustment of the body based on a hinge connection so that an air-inflated airbag is positioned vertically with respect to the ground.

[0121] In addition, according to one embodiment of the present invention, a safety sign device is provided with a wing that holds the airbag being injected with air from the bottom, thereby allowing the airbag to be attached more stably to the vehicle while minimizing the influence of external factors such as wind to indicate danger to a rear vehicle.

[0122] In addition, according to one embodiment of the present invention, a safety sign device can effectively prevent loss when the safety sign device is detached from the vehicle by additionally providing a string unit that can be used as a safety auxiliary strap.

[0123] In addition, according to one embodiment of the present invention, the operation sequence, usage method, precautions, etc. of the device are inscribed on the outer surface of the device so that the driver can utilize it more easily when a dangerous situation occurs, and accordingly, user convenience can be further improved.

[0124] In addition, according to one embodiment of the present invention, by implementing hinge connections on both the upper and lower sides of the body, air inflation of the airbag can be implemented by selectively utilizing an upward air inflation method or a forward air inflation method depending on user preference, vehicle environment, and accident type.

[0126] As described above, the best embodiments have been disclosed in the drawings and specification. Specific terms have been used herein, but they are used only for the purpose of describing the invention and are not intended to limit the meaning or the scope of the invention as described in the claims.
