Summary of the Invention

Problems to be Solved by the Invention

[0004] Since the instruments of Patent Documents 1 and 2 have a relatively large contact area with the body, there is a problem that the wearer is likely to feel discomfort.

Means for Solving the Problems

[0005] The technology disclosed in this specification can be realized in the following forms. One embodiment disclosed herein is a ventilation spacer for trousers, which is attached to the inside of the waistband along the rear of the trousers and forms a ventilation path between the body and the waistband that connects the inside and outside of the trousers. The ventilation spacer for trousers comprises a strip-shaped base portion that is in the shape of a band along the waistband, and a folded plate portion that forms a plurality of convex ridges, each having alternating triangular apex and triangular valleys in the longitudinal direction of the strip-shaped base portion. The strip-shaped base portion has a first surface configured to be attachable to the waistband, and a second surface located on the back side of the first surface and joined to each of the valleys in the folded plate portion. The ventilation path includes a first ventilation path formed between the second surface and the plurality of convex ridges, and a second ventilation path formed between the plurality of convex ridges and the body. The strip-shaped base portion and the folded plate portion have the flexibility to bend convexly outward in the longitudinal direction of the trousers. The cross-sectional shape of the apex is curved. When the ventilation spacer for the trousers is attached to the trousers, the lower end of the protrusion facing downward on the trousers, when viewed from a side direction parallel to the first surface and perpendicular to the length direction of the protrusion, is the bottom of the valley. The part where the end and the other end are connected More towards the aforementioned top The part where the end and the other end are connected It is inclined so that it is closer to the center in the longitudinal direction of the aforementioned protrusion.

[0006] (1) One embodiment disclosed herein is a trouser ventilation spacer attached to the inside of the waistband of trousers. The trouser ventilation spacer forms a ventilation path between the body and the waistband that connects the inside and outside of the trousers. The trouser ventilation spacer comprises a strip-shaped base portion that is in the shape of a band along the waistband, and a folded plate portion having a plurality of convex ridges arranged alternately in the longitudinal direction of the strip-shaped base portion. The strip-shaped base portion has a first surface configured to be attachable to the waistband, and a second surface located on the back side of the first surface and joined to each of the convex ridges in the folded plate portion. The ventilation path includes a first ventilation path formed between the second surface and the plurality of convex ridges, and a second ventilation path formed between the plurality of convex ridges and the body. The strip-shaped base portion and the folded plate portion have flexibility to bend convexly outward in the longitudinal direction of the trousers. This type of trouser ventilation spacer efficiently forms a first and second ventilation path with its raised ridges, while the multiple spaced, linear peaks come into contact with the body, reducing discomfort felt by the wearer.

[0007] (2) In the above-described form of the ventilation spacer for trousers, the end of the protrusion may be inclined from the bottom of the valley towards the center in the longitudinal direction of the protrusion. With this form of ventilation spacer for trousers, the discomfort felt by the wearer due to the end of the protrusion coming into contact with the body can be reduced.

[0008] (3) The ventilation spacer for trousers in the above configuration may be divided with a gap in at least one of the front-to-back and left-to-right directions of the waist portion. With this configuration of the ventilation spacer for trousers, the division in the front-to-back direction reduces pressure on the area around the iliac crest of the body, thereby further reducing discomfort felt by the wearer. Furthermore, the division in the left-to-right direction on the back of the waist portion reduces pressure on the area around the lumbar spine of the body, thereby further reducing discomfort felt by the wearer. Furthermore, the division in the left-to-right direction on the front of the waist portion reduces pressure on the area around the abdomen of the body, thereby further reducing discomfort felt by the wearer. In addition, by interlocking the top portion 123 and the bottom portion 124 of two adjacent ventilation spacers for trousers separated by a gap, the trousers can be folded with the ventilation spacers attached.

[0009] The technologies disclosed herein are not limited to trouser ventilation spacers, but can also be implemented in forms such as trousers equipped with trouser ventilation spacers, coveralls equipped with trouser ventilation spacers, and methods for ensuring ventilation of trousers. [Brief explanation of the drawing]

[0010] [Figure 1] This is a front view showing a ventilation spacer for trousers. [Figure 2] This is a top view showing a ventilation spacer for trousers. [Figure 3] This is a right side view showing a ventilation spacer for trousers. [Figure 4] This is a rear view showing a ventilation spacer for trousers. [Figure 5] This is an explanatory diagram showing trousers with ventilation spacers attached. [Figure 6] This is an explanatory diagram showing how trousers are folded with the ventilation spacers for trousers attached. [Modes for carrying out the invention]

[0011] Figure 1 is a front view showing the trouser ventilation spacer 100. Figure 2 is a top view showing the trouser ventilation spacer 100. Figure 3 is a right side view showing the trouser ventilation spacer 100. Figure 4 is a rear view showing the trouser ventilation spacer 100. Figure 5 is an explanatory diagram showing trousers 200 with the trouser ventilation spacer 100 attached.

[0012] The trouser ventilation spacer 100 is a device for preventing stuffiness inside the trousers 200. The trouser ventilation spacer 100 is configured to be attached to the inside of the waist portion 210 of the trousers 200, along the waist portion 210. The waist portion 210 of the trousers 200 corresponds to the part of the human body BD.

[0013] The trouser ventilation spacer 100 comprises a strip-shaped base portion 110 and a folded plate portion 120. The strip-shaped base portion 110 and the folded plate portion 120 have the flexibility to bend outward in a convex shape along the longitudinal direction LD of the trousers 200.

[0014] The strip-shaped base portion 110 of the trouser ventilation spacer 100 is a member that forms a strip along the waist portion 210. The strip-shaped base portion 110 is made of synthetic resin (for example, polypropylene). The strip-shaped base portion 110 has an attachment surface 111 and a ventilation surface 112.

[0015] The mounting surface 111 of the band-shaped base 110 is a first surface configured to be attachable to the waist portion 210 of the trousers 200. A hook-and-loop fastener 131 is attached to the mounting surface 111 with adhesive. The surface of the hook-and-loop fastener 131 is napped in a hook shape. The hook-and-loop fastener 131 can be attached to a hook-and-loop fastener 132 fixed to the waist portion 210 of the trousers 200. The surface of the hook-and-loop fastener 132 is napped in a loop shape. As a result, the trouser ventilation spacer 100 is detachable from the waist portion 210 of the trousers 200.

[0016] The ventilation surface 112 of the strip-shaped base portion 110 is a second surface located on the back side of the mounting surface 111. The ventilation surface 112 is joined to each of the valley bottom portions 124 in the corrugated plate portion 120.

[0017] The corrugated plate portion 120 is a member having a plurality of ridges 122 in which the top portions 123 and the bottom portions 124 are alternately arranged in the longitudinal direction LD of the strip-shaped base portion 110. The corrugated plate portion 120 is made of a synthetic resin (for example, made of polypropylene).

[0018] The plurality of ridges 122 extend along the short side direction SD of the strip-shaped base portion 110. The cross-sectional shape of the top portion 123 viewed from the vertical direction is preferably curved in order to reduce the sense of incongruity given to the body BD. The end portions 125 and 126 of the ridge 122 are inclined from the bottom portion 124 toward the center in the length direction (short side direction SD) of the ridge 122 from the bottom portion 124 to the bottom portion 124.

[0019] The ventilation spacer 100 for trousers forms ventilation paths VP1 and VP2 that connect the inside and the outside of the trousers 200 between the human body BD and the waist portion 210. The ventilation path VP1 is a ventilation path formed between the ventilation surface 112 of the strip-shaped base portion 110 and the plurality of ridges 122 in the corrugated plate portion 120. The ventilation path VP2 is a ventilation path formed between the plurality of ridges 122 in the corrugated plate portion 120 and the human body BD.

[0020] In the example of FIG. 5, the trousers 200 include four ventilation spacers 100 for trousers. The ventilation spacers 100 for trousers in FIG. 5 are arranged by being divided into four at intervals SP in the front-back direction and the left-right direction of the waist portion 210, respectively. The ventilation spacer 100 for trousers may be arranged by being divided into two at intervals SP in the front-back direction of the waist portion 210. The ventilation spacer 100 for trousers may be arranged by being divided into two at intervals SP in the left-right direction of the waist portion 210.

[0021] The ventilation spacers 100 for trousers, which are divided and arranged with spacing SP between them in the front-to-back direction of the waist portion 210, can reduce pressure on the iliac crest of the body BD, thereby further reducing discomfort felt by the wearer. Furthermore, the ventilation spacers 100 for trousers, which are divided and arranged with spacing SP between them in the left-to-right direction on the rear side of the waist portion 210, can reduce pressure on the lumbar spine of the body BD, thereby further reducing discomfort felt by the wearer. Furthermore, the ventilation spacers 100 for trousers, which are divided and arranged with spacing SP between them in the left-to-right direction on the front side of the waist portion 210, can reduce pressure on the abdominal area of ​​the body BD, thereby further reducing discomfort felt by the wearer.

[0022] Figure 6 is an explanatory diagram showing how the trousers 200 are folded with the trouser ventilation spacers 100 attached. As shown in Figure 6, the trousers 200 can be folded with the trouser ventilation spacers 100 attached by interlocking and overlapping the top 123 and bottom 124 of two adjacent trouser ventilation spacers 100 separated by a gap SP.

[0023] As described above, the trouser ventilation spacer 100 efficiently forms ventilation paths VP1 and VP2 with the convex ridges 122, while the discomfort felt by the wearer is reduced by contacting the body BD at multiple spaced linear peaks 123.

[0024] Furthermore, ventilation between the inside and outside of the trousers 200 is particularly hindered when the waist portion 210 of the trousers 200 is fastened with a waist belt (not shown). However, with the trouser ventilation spacer 100, ventilation between the inside and outside of the trousers 200 when the waist belt is fastened can be efficiently formed by the protrusions 122 to create ventilation paths VP1 and VP2. In addition, trousers 200 equipped with the trouser ventilation spacer 100 can be used in combination with an air-conditioned garment (not shown) which is a jacket equipped with an electric fan, to effectively ventilate between the inside and outside of the trousers 200.

[0025] Furthermore, in a cross-section viewed from above, the ventilation surface 112 of the strip-shaped base 110 is joined at a point to the valley bottom 124 of the folded plate portion 120, so the strip-shaped base 110 can flexibly deform to conform to the shape of the waist of the body BD. Also, the protrusions 122 of the folded plate portion 120 form a triangle together with the strip-shaped base 110, so sufficient strength can be ensured to maintain the shape of the ventilation path VP2. In addition, in a cross-section viewed from above, the protrusions 122 of the folded plate portion 120 make point contact with the body BD at the top 123, so by reducing the contact area with the body BD, ventilation by the ventilation path VP2 around the body BD that is in contact with the protrusions 122 can be effectively ensured.

[0026] Furthermore, the ends 125 and 126 of the protrusions 122 are inclined from the bottom 124 to the top 123 towards the center of the protrusions 122 in the longitudinal direction. This trouser ventilation spacer 100 reduces the discomfort felt by the wearer due to the ends 125 and 126 of the protrusions 122 coming into contact with the body BD.
