Description

Technical Field

[0001] This utility model relates to a device for extending temperature conversion time. The device is worn under helmets, clothing, etc., or placed on bedding such as pillows and mats, and comes into direct or indirect contact with the body to keep warm or cold. Background Technology

[0002] The description of related technologies generally refers to the fact that clothing is worn as an accessory to prevent body temperature from rising in high-temperature working environments or during summer. For example, there are cooling vests that can have multiple cooling bags attached to the front or back of the garment. These vests are formed by a bag-shaped cooling material enclosure, which is divided into multiple sections by welded seams. PCM material, as the cooling material, is sealed within the cooling material enclosure. The welded sections restrict unnecessary movement of the PCM material between the outer fabric and the lining.

[0003] However, in traditional personal accessories that include cooling materials, the cooling effect cannot last for a long time because the cooling material has a large contact area with the sides of the body. Therefore, there is a need for a structure that can make the cooling effect last longer.

[0004] This utility model was made in view of the above-mentioned needs, and its purpose is to provide a tool that can extend the temperature conversion time and has a longer heat preservation or cold preservation effect than previous tools. Utility Model Content

[0008] And a sealing sheet, facing the storage portion installed in the substrate and sealing the temperature regulating material;

[0009] The storage part is a device for extending the temperature conversion time. One end of the storage part is a front end protruding from the substrate, and the other end is a rear end connected to the substrate. The contact surface of the front end that directly or indirectly contacts the body is smaller than the contact surface of the rear end that contacts the substrate.

[0011] Preferably, the substrate includes a central portion disposed at the center and peripheral portions formed radially from the central portion and spaced apart from each other by grooves, the grooves being edges having groove bottoms corresponding to the outer periphery of the central portion when viewed from above.

[0012] Preferably, the receiving portion has a second-, third-, or fourth-order stepped shape protruding from the base end to the distal end of the substrate, or a truncated cone or truncated pyramid shape protruding from the base end to the distal end.

[0013] The temperature conversion time extension device and its manufacturing method according to this utility model can provide the following excellent effects:

[0014] In this invention, the contact surface of the contact end of the storage part is smaller than the surface of the base end, which allows the heat preservation and cold preservation effects to be maintained for a longer time than in the traditional method. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Temperature transition time extension tools are used in summer or high-temperature environments, or winter or low-temperature environments, and are applied directly or indirectly to the body to keep it cool or warm. These tools can be installed, for example, inside helmets or clothing, or on bedding such as pillows or mattresses to regulate body temperature.

[0040] Example 1:

[0041] Reference Figures 1 to 3 The device 100 for extending temperature conversion time includes a substrate 10, a storage section 20 installed in the substrate 10, a temperature regulating material 30 stored in the storage section 20, and a sealing sheet 40 for sealing the temperature regulating material 30.

[0042] The substrate 10 is made of a resin sheet such as thermoplastic polyurethane (TPU). The substrate 10 is formed to match the shape of the body part to which it is attached. For example, when worn on the upper body, the substrate 10 includes a first sheet 11 positioned opposite to the front of the body, a second sheet 12 positioned opposite to the back of the body, and a third sheet 13 positioned opposite to the best side of the body.

[0043] The first sheet 11, the second sheet 12, and the third sheet 13 are configured such that they can be detachably engaged with each other via connecting straps 14 (14A, 14B, 14C), for example, as connecting devices. The connecting straps 14 include connecting fasteners, Velcro, buckles, and other connecting components, and are configured to be operable by hand and fingers.

[0044] The first sheet 11 is formed from two sheets: a first right sheet 11A and a first left sheet 11B. The first right sheet 11A and the first left sheet 11B are, for example, formed in a linearly symmetrical shape. The first right sheet 11A and the first left sheet 11B are each composed of a chest portion 11A1 and 11B1 with a smaller area on the chest side of the body, and an ventral portion 11A2 and 11B2 with a larger area on the abdominal side of the body than the chest portion 11A1 and 11B1.

[0045] In addition, both the first right sheet 11A and the first left sheet 11B have a connecting strap 14A, which is connected to the connecting strap 14B of the second sheet 12 installed at the upper end of the chest side portions 11A1 and 11B1.

[0046] In addition, the first right sheet 11A and the first left sheet 11B have a connecting strap 14A of a third sheet 13 at two locations mounted on the ventral sides 11A2 and 11B2.

[0047] In the first right sheet 11A and the first left sheet 11B, the storage portions 20 are arranged longitudinally and spaced apart from each other. Furthermore, the storage portions 20 located at the corners of the first right sheet 11A and the first left sheet 11B are formed with beveled edges, while the other portions are formed as rectangular shapes when viewed from above. Because the storage portions 20 of the first right sheet 11A and the first left sheet 11B are arranged in a straight line, they can be bent at points between the lines and can be worn along the curves of the body.

[0048] Therefore, the contact surface 24 of the storage section 20 can easily come into indirect or direct contact with the body. Furthermore, the structure of the storage section 20 will be described later.

[0049] The second sheet 12 is placed on the back of the body, and the periphery of the first sheet is formed into a curve corresponding to the body part to follow the body. The second sheet 12 has connecting straps 14B, 14B, which are connected to connecting straps 14A, 14A installed at two positions on the upper side of the first sheet 11, and the connecting straps 14B, 14B are arranged at the left and right positions on the upper side.

[0050] Furthermore, the second sheet 12 has connecting strips 14B, 14B that connect to the third sheet 13, and these connecting strips 14B, 14B are arranged vertically at intervals on the left and right surfaces. The storage portions 20 installed in the second sheet 12 are arranged in two middle rows starting from the center of the sheet, and two additional rows are arranged on the left and right sides of the two middle rows.

[0051] The storage sections 20 installed in the second sheet 12 are arranged symmetrically from the center. Furthermore, in the storage sections 20, the three columns on the left are spaced apart by tilting to the left when viewed vertically from the center, and the three columns on the right are arranged by tilting to the right. The storage sections 20 are arranged in two central rows such that their volume and area increase downwards from the center.

[0052] In addition, besides the two at the top, the storage sections 20 are arranged in the two middle rows, so that the volume and area of ​​the storage sections increase from the center upwards. Furthermore, in the two columns arranged upwards from the center, the storage sections 20 are arranged in a manner that decreases in volume and area as they rise from the center. Additionally, the storage sections 20 are arranged downwards from the center in two columns, with different volumes and areas.

[0053] By forming the storage section 20 in a row that slopes vertically outward from the center, the second sheet 12 can easily bend along the shape of the latissimus dorsi, trapezius, and other muscles of the back when worn on the body. Therefore, the contact surface 24 of the storage section 20 can easily come into direct or indirect contact with the body. The detailed structure of the storage section 20 will be described later.

[0054] The third piece 13 is disposed on the side under the armpit of the human body and includes a third right piece 13A and a third left piece 13B. The third right piece 13A and the third left piece 13B are formed into a rectangular shape with rounded corners. The third right piece 13A and the third left piece 13B each have four connecting straps 14C, which are respectively connected to the connecting straps 14A and 14B of the first right piece 11A, the first left piece 11B and the second piece 12 on the left and right sides.

[0055] The third right piece 13A and the third left piece 13B have two rows of storage sections 20 arranged in a straight line with a gap between them. In addition, in the third right piece 13A and the third left piece 13B, the storage section 20 located at the corner is formed as a top-view triangle, and the other storage sections 20 are formed as top-view rectangles.

[0056] The third right sheet 13A and the third left sheet 13B are curved along the curvature of the body side, and the arrangement of the storage portion 20 allows the contact surface 24 to easily come into direct or indirect contact with the body. The third right sheet 13A and the third left sheet 13B are formed to be less than half the length of the first sheet and the second sheet.

[0057] like Figure 4 and Figure 5 As shown, the storage section 20 is a part for storing temperature-regulating materials used for warmth or cold preservation. The contact surface 24 at the front end of the storage section 20 is smaller than the surface of the first step 21 at the base end.

[0058] In other words, the area W2 of the contact surface 24 of the third step 23 at the front end of the receiving part 20 is smaller than the area W1 of the surface of the base end portion 10. In addition, the surface of the base end portion refers to the portion with an area W1 that is inside the portion that is the base end portion 10 of the receiving part 20.

[0059] For example, the storage section 20 is formed in a stepped shape. In the case of three steps, the area W2 of the contact surface 24, which is the upper surface of the third step section 23, is smaller than the area W1 of the first step section 21.

[0060] The receiving portion 20 is integrally formed with the substrate 10, for example, and can be formed on the substrate 10 using a punch and a die, or by injection molding between an upper and a lower die. Alternatively, the temperature regulating material 30 can be pre-received in the receiving portion 20, sealed with a sealing sheet 40, and then adhered to the substrate 10 (see reference). Figure 14 (a)~ Figure 14 (d)).

[0061] In other words, the shape of the storage section 20 is not limited as long as the contact surface 24, which serves as the front end, is smaller than the surface of the base end. The storage section 20 stores temperature-regulating material 30 that maintains a warm or cold temperature.

[0062] like Figure 4 and Figure 5 As shown, when the storage section 20 is stepped, a sufficient amount of temperature regulating material 30 can be ensured in the first step 21, the second step 22 and the third step 23, which serve as the base.

[0063] Since the contact surface 24, which directly or indirectly contacts the body, is smaller than the first step portion 21, which serves as the base end, the heat-insulating or cold-insulating effect of the temperature-regulating material 30 can be maintained for a long time. Furthermore, as an example, the storage portion 20 is formed such that the centers of each layer are aligned in the plane.

[0064] Furthermore, while the top view shape of each step is the same, the top view shape of each step can also be different. Additionally, even if the shapes of the steps are similar or different, the centers of the planes of the steps can be aligned, or they can be located in different positions.

[0065] like Figure 5 As shown, the area W2 of the contact surface 24 is preferably 10% or more smaller than the area W1 of the first step 21, which serves as the base, more preferably 20% or more, 30% or more, and even more preferably 40% or more, 50% or more. In this way, since the area W2 of the contact surface 24 is smaller than the area W1 of the first step 21, it is possible to maintain a heat preservation or cold preservation effect of 20% to 50% or more for a longer period than in the prior art.

[0066] Furthermore, if the area W2 of the contact surface 24 is less than 10% smaller than the area W1 of the base end, although there is an effect, it is smaller compared to the case where the area W2 of the contact surface 24 and the area W1 of the base end are equal, making it difficult to claim the heat preservation or cold preservation effect as practical. Therefore, it is preferable that the area W2 of the contact surface 24 is 10% or more smaller than the area W1 of the proximal end, so that it is easier to demonstrate that the product has a better heat preservation or cold preservation effect for a longer period of time than conventional products.

[0067] The temperature regulating material 30 stored in the storage section 20 is, for example, a latent heat storage material (PCM: phase change material). This temperature regulating material 30 is a material that repeatedly undergoes phase changes from dissolution to solidification and can be used an unlimited number of times over a long period. By changing the material used, the temperature regulating material 30 can be used within a temperature range capable of maintaining heat or a temperature range capable of maintaining cold. Note that the temperature regulating material 30 is not limited to latent heat storage materials, and other existing materials can be used.

[0068] The sealing sheet 40 is used to seal the temperature-regulating material 30 stored within the housing 20 for its storage. The sealing sheet 40 is preferably formed of the same material as the substrate sheet 10, for example. The sealing sheet 40 is made of a resin sheet such as thermoplastic polyurethane (TPU). The sealing sheet 40 is installed by hot-pressing it onto the substrate sheet 10 at the position facing the housing 20 or by bonding it to the substrate sheet 10 using an adhesive.

[0069] The sealing sheet 40 is formed, for example, with dimensions facing the first sheet 11, the second sheet, and the third sheet 13, respectively. Furthermore, the sealing sheet 40 may have the same thickness as the base sheet 10, or it may be thicker or thinner. Additionally, the sealing sheet 40 may be configured to seal all the receiving portions 20 by means of separate sheets for each mounting portion of the first sheet 11, the second sheet 12, and the third sheet.

[0070] In the temperature conversion time extension appliance 100 configured in this way, for example, such as Figure 6 As shown, the contact surface 24 of the storage portion 20 of the first sheet 11 contacts the front side of the main body, and the contact surface 24 of the storage portion 20 of the second sheet 12 contacts the rear side of the main body.

[0071] In addition, the contact surface 24 of the storage section 20 of the third piece 13 can contact the side of the main body. The area W2 of the contact surface 24 of each storage section 20 that contacts the body is smaller than the area W1 of the base end of the storage section 20, i.e., the first step 21.

[0072] Therefore, compared to existing structures with roughly the same areas W1 and W2, the heat preservation or cold preservation effect of the temperature regulating material 30 in the storage section 20 can be extended by 20% to 50% or more over a longer period. For example, if the temperature regulating material 30 uses a latent heat axial flow heating material that undergoes a phase change at 24 degrees Celsius, and the contact surface 24 is in direct contact with a body at a temperature of 36 degrees Celsius, whether through indirect or direct contact with a shirt, the cold preservation time can be increased from 3 to 4 hours in the conventional configuration to 6 to 8 hours.

[0073] Example 2:

[0074] Regarding Example 2, please refer to Figures 7 to 11 A description will be provided. Furthermore, for structures identical to those already described, the same reference numerals will be used, and their descriptions will be omitted.

[0075] As an example, the temperature transition time extension device 100B, as shown in the figure, is used by wearing a hat, etc. 11. Wearing a helmet HM. Temperature transition time extension tool 100B, as... Figure 7 and 8 As shown, the temperature conversion time extension tool 100B includes a substrate 50, a storage section 20, and a temperature regulating material 30 stored in the storage section 20 (see [reference]). Figure 5 ) and sealing sheet 60. In addition, the temperature conversion time extension tool 100B has connecting straps 70 attached to the inside of the helmet HM at two opposite positions on the left and right sides.

[0076] The substrate 50 includes a central portion 51 and peripheral portions 52 arranged radially from the central portion 51. The central portion 51 is formed in a generally circular shape, and the receiving portion 20 is arranged to surround the center. The peripheral portions 52 are arranged to extend radially from the central portion 51 and are spaced apart from each other via grooves 53. The peripheral portions 52 are continuously formed into a fan shape from the central portion 51.

[0077] Furthermore, each peripheral portion 52 has a side portion that is separated from the others by a groove 53. The groove 53 that separates the peripheral portions 52 is a side portion having a length such that the groove bottom 54 becomes the outer periphery of the central portion 51 when viewed from above. As an example, the outer periphery of the central portion 51 is formed as a straight section. Note that the groove bottom 54, as the outer periphery of the central portion 51, can also be circumferential (curved, arc-shaped), etc. Since the groove bottom 54 has a certain length, such as Figure 7 As shown, the substrate 50 can be formed along the plane, and can be as follows: Figure 9 and Figure 10 As shown, it bends easily along the head it is worn on.

[0078] Although the top view of the peripheral portion 52 shows a fan shape, it can also be other shapes such as a rectangle. Furthermore, the substrate sheet 50 is preferably formed of the same material as the substrate sheet 10 described above.

[0079] Regarding storage section 20, although in Figure 1 and Figure 6 The shapes are different, but they are the same as those already described. For example... Figure 7 As shown, the receiving portion 20 is formed to protrude in a stepped manner from one surface of the substrate 50 toward another surface. In addition, the receiving portion 20 may be formed such that the center of the first step 21, the center of the second step 22, and the center of the third step 23 are aligned with each other, or they may not be aligned with each other.

[0080] Furthermore, the top view shape of each layer is not particularly limited. The contact surface 24 at the top of the storage section 20 is formed to be smaller than the surface of the base end of the storage section 20, and has the above-described structure.

[0081] The temperature regulating material 30 stored in the storage section 20 is the same as that already described.

[0082] Furthermore, the sealing sheet 60 is arranged facing the receiving portion 20, and here, as an example, it is attached to the substrate 50 facing the substrate 50. The sealing sheet 60 is formed to have the same planar shape as the substrate 50. Preferably, the sealing sheet 60 is formed of the same material as the substrate 50.

[0083] Furthermore, the connecting strap 70 is connected to the peripheral part 52 and installed facing each other. The connecting strap 70 is adapted to be attached to a headband located inside the helmet HM.

[0084] Because the temperature conversion time extension tool 100B is constructed as described above, by wearing the helmet HM on the head and attaching the connecting strap 70 to the headband of the helmet HM, the contact surface 24 of the storage part 20 is in direct or indirect contact with the head, and the temperature of the head can be kept comfortable by the temperature regulating material 30.

[0085] Note that the helmet HM can be worn while wearing a paper or non-woven cap for the helmet's interior, and can also be applied when the contact surface 24 indirectly contacts the head. When the temperature transition time extension tool 100B is, for example, a temperature regulating material 30 for refrigeration, a comfortable environment can be maintained for a longer period of time without raising the interior of the helmet HM to a high temperature, compared to conventional environments.

[0086] Next, we will refer to Figure 12 Methods for manufacturing appliances 100 and 100B for extending temperature transition time are described.

[0087] Note that the temperature conversion time extension tool 100 and the temperature conversion time extension tool 100B differ only in the shape of the substrate and the sealing sheet, while the other construction and processes are the same.

[0088] The manufacturing method S10 for the appliance for extending temperature conversion time is performed by steps including a cutting step S11, a storage part forming step S12, a temperature regulating material sealing step S13, and a sealing step S14.

[0089] Cutting step S11 involves cutting the substrates 10 and 50 into portions corresponding to those to be worn on the body. Therefore, in cutting step S11, when the substrate 10 is attached to the body, it is cut into a first piece 11, a second piece 12, and a third piece 13. Furthermore, in cutting step S11, when the substrate 50 is attached to the head, it is cut into a central portion 51 and a peripheral portion 52.

[0090] The storage portion forming step S12 is a process of forming a plurality of storage portions that protrude from one side of the substrate sheet 10 or substrate sheet 50 at intervals. In the storage portion forming step S12, a predetermined number of storage portions 20 with predetermined shapes are formed at predetermined positions. For example, in the case of the first sheet 11, such as... Figure 1 As shown, the storage section 20 is configured such that 12 storage sections 20 are arranged in two rows in the chest side section 11a1 of the first right sheet 11A, and 15 storage sections 20 are arranged in three rows in the ventral side section 11a2.

[0091] In step S12, the storage portion 20 is formed on the substrates 10 and 50 using a stamping device employing a male mold and a female mold, for example. The formed storage portion 20 is configured such that the contact surface 24 on the front end side is smaller than the surface on the base end side.

[0092] The temperature-regulating material storage step S13 is the step of storing (filling) temperature-regulating material for heat preservation or cold preservation from an opening on one side of the storage section. In the temperature-regulating material storage step S13, for example, latent heat storage material (PCM) is filled as temperature-regulating material 30 in a liquid or gel state, or it is stored in the storage section 20 after being cooled to a solid state.

[0093] Sealing step S14 is the process of sealing the opening of the storage section containing temperature-regulating material with sealing sheets. In sealing step S14, sealing sheets 40 and 60 are pre-cut into the same shape as the base sheets 10 and 50. The cut sealing sheets 40 and 60 are then placed face-to-face with the base sheets 10 and 50 and welded or pressed to the periphery of the opening of the storage section 20 by heat or pressure. Furthermore, in sealing step S14, sealing sheets 40 and 60 are placed face-to-face with the base sheets 10 and 50. This connection ensures that all facing positions are welded or pressed together.

[0094] Subsequently, connecting straps 14 and 70 are installed at predetermined positions where the sealing sheet 40 and the substrate 10 are connected, or at predetermined positions where the sealing sheet 60 and the substrate 50 are connected. As a result, a temperature conversion time extension tool 100 or a temperature conversion time extension tool 100B is manufactured. In the method S10 for manufacturing a temperature conversion time extension tool, each step is performed as described above, thus enabling the manufacture of temperature conversion time extension tools 100 and 100B that can increase the heat preservation or cold preservation time by 20% or more compared to conventional tools.

[0095] Note that method S10, used to manufacture tools for extending temperature conversion time, is given as an example. Figure 14 The method for using the structure shown to manufacture tools for extending temperature transition time can be performed according to the following procedure.

[0096] In other words, in the manufacturing method S10 of the temperature change time extension device, in the sealing process, such as Figure 13 As shown, at the positions where the sealing sheets 40 and 60 face the receiving portion 20, the sealing sheets 40 and 60 are pressed or welded to the substrates 10 and 50, so that the temperature regulating material 30 in the receiving portion 20 is filled without mixing with air. Thereafter, the step of attaching the cover sheet 80 facing the sealing sheets 40 and 60 can be performed before attaching the connecting strip 14.

[0097] The cover plate 80 is connected to the sealing plates 40 and 60, and has an open space AS facing the storage section 20. Therefore, the cover plate 80 appears flat from the outside and does not impair the appearance. Note that the connection between the cover plate 80 and the sealing plates 40 and 60 can be performed using adhesives, welding, or crimping, and there are no particular limitations.

[0098] In addition, in the manufacturing method of the temperature conversion time extension tool, Figure 14 The process shown can include the following steps: forming a single unit of a pre-installed storage portion 20N, filling the single storage portion 20N with a temperature-regulating material 30, sealing the filled temperature-regulating material, and attaching the storage portion sealed with the temperature-regulating material to a substrate. When the storage portion 20N is formed separately, a flange portion 25 is formed around the opening at the lower end of the storage portion 20N.

[0099] As an example, the storage portion 20N is formed in a stepped shape and has a contact surface 24 at the front end, which is smaller than the base end that rises from the flange portion 25.

[0100] Next, temperature-regulating material 30 is filled into the opening side of the storage section 20N. Then, the storage section 20N filled with temperature-regulating material 30 is sealed by a sealing sheet 40N. The sealing sheet 40N seals the temperature-regulating material 30 inside the storage section 20N by being opposite to and connected to the flange portion 25 of the storage section 20N. The shape, size, and number of the storage sections 20N are preset.

[0101] The storage section 20N was prepared as follows Figure 1 or Figure 7 The shape, size, and quantity are shown. Then, the separately formed storage section 20N is placed at a predetermined position on the pre-formed substrate 10N. The storage section 20N is attached to the back of the sealing sheet by, for example, using an adhesive to bond it to the substrate 10N. Afterwards, a connecting strip is attached to create a device for extending the temperature conversion time, thus completing the process.

[0102] Note that the storage unit 20N can be manufactured as a single unit, or two, three, or four or more storage units can be manufactured as a single unit.

[0103] In addition, appliances that extend temperature transition time can also be used in bedding, such as pillows (HL) and mattresses (ML), for example... Figure 1 and 2 As shown. (Refer to...) Figure 15 and Figure 16 The construction of the temperature conversion time extension devices 100C and 100D differs in shape from the previously described construction, but has the same construction, and their detailed description will be omitted.

[0104] like Figure 15 As shown, the temperature transition time extension tool 100C has storage portions 20 formed at intervals on a rectangular substrate 10, and is mounted such that the contact surface 24 faces the head. The temperature transition time extension tool 100C is used, for example, by placing or wrapping the substrate sheet 10 on a pillow HL, and then wrapping the pillow HL with a towel or the like.

[0105] In addition, such as Figure 16 As shown, multiple temperature conversion time extension tools 100D are placed on the mattress ML for use. In each temperature conversion time extension tool 100D, storage sections 20 are spaced apart on a rectangular base plate 10. The temperature conversion time extension tools 100D are configured such that multiple tools 100D can be used to cover the entire size of the mattress ML. Thus, by making the size of the temperature conversion time extension tools 100D smaller than the entire mattress ML, the temperature conversion time extension tools 100D can be easily stored in a refrigerator or similar container, making operation convenient.

[0106] In the temperature conversion time extension tools 100C and 100D, the area W2 of the contact surface 24 is smaller than the area W1 of the base end face, thus extending the temperature adjustment time compared to conventional tools.

[0107] In addition, the shape of the storage section described above can also be as follows: Figure 17 and Figure 18 That's alright. The following examples, 1 through 5, illustrate the shape of the storage section. Furthermore, identical reference numerals are used for identical structures, and their descriptions are omitted.

[0108] like Figure 17 As shown in (a), the storage section 20B, as a first variation, is formed into a two-stage assembly. The area W2 of the contact surface 24b at the front end of the storage section 20B is smaller than the area W1 of the surface at the base end. Since the storage section 20B has fewer stages, it is easy to manufacture.

[0109] like Figure 17 As shown in (b), the storage section 20C, as a second modification, is formed in four layers. The area W2 of the contact surface 24c at the front end of the storage section 20C is smaller than the area W1 of the surface at the base end. Since the storage section 20C has more layers, the capacity for holding temperature-regulating material can be increased.

[0110] like Figure 17 As shown in (c), the receiving portion 20D, as a third variation, is formed in the shape of a frustum or truncated pyramid. The area W2 of the contact surface 24d at the distal end of the receiving portion 20D is smaller than the area W1 of the surface at the proximal end. The receiving portion 20D has a simpler shape than a stepped shape, and is therefore easier to manufacture.

[0111] like Figure 18As shown in (a), the storage portion 20E, as the fourth variation, is formed in a dome shape, and the contact surface 24e at the front end is flat, with an area W2 smaller than the area W1 of the base end surface. Although the contact surface 24e of the storage portion 20E is a flat surface, it can be formed as a curved surface as shown by the dashed line. In this case, the storage portion 20E will be formed as a hemisphere. When formed as a hemisphere, the contact surface 24e1 is the upper 1 / 3 of the hemisphere, but smaller than the area W1 of the surface at the base end of the hemisphere.

[0112] like Figure 18 As shown in (b), the storage portion 20F of the fifth modification has a stepped curved surface. The contact surface 24f, which serves as the front end of the storage portion 20F, is formed by a curved surface. Furthermore, the area W2 of the contact surface 24f is smaller than the area W1 of the base end face.

[0113] As described above, regardless of the shape of the storage section, the area W2 of the contact surface is always smaller than the area W1 of the base surface. Therefore, compared with the prior art, the effect of the temperature-regulating material stored in the storage section can be extended by more than 20%. Furthermore, when the storage section is formed in a stepped shape, the height of each step and its shape when viewed from above are not limited. Additionally, the top-view shape of the contact surface is not limited to circular, elliptical, or square; the contact surface can also be planar or curved.

[0114] Additionally, as a device for extending temperature transition time, one is shown to be worn on the head and another on the torso, but it can also be worn under trousers or a skirt to keep the legs warm or cold. When keeping the legs warm or cool, a thin, elongated base is provided, facing the outer and / or inner surface of the leg above the knee, and for example... Figure 1 The shape of the third sheet shown. One can be used.

Furthermore, parts of the structure of each embodiment can be added to, deleted from, or replaced with other structures.

[0116] In addition, the above-mentioned mechanisms and structures are only necessary for illustration and not all of them need to be shown in the product.

[0117] The temperature conversion time extension device according to this embodiment can be worn directly or indirectly on the body in summer or high-temperature environments when the temperature is high, or in winter or low-temperature environments when the temperature is low.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
