Description

[Technical Field]

[0001] The present invention relates to air-conditioning clothing in which stitching is applied to the fabric of the clothing to prevent expansion. [Background technology]

[0002] In recent years, air-conditioned clothing that has a fan attached to the waist and draws outside air into the clothing to cool the wearer has become widely used.

[0003] Due to the increasing performance of fans, when air is taken into the air-conditioned clothing, the clothing expands, restricting the wearer's movement and also causing the clothing's contours to expand and deform, which can be a problem as it makes the clothing less fashionable. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2010-18941 [Patent Document 2] Patent Publication No. 2007-291552

[0005] The garment in Patent Document 1 is a so-called down coat, and discloses a structure in which feathers (3) are stuffed between an outer layer (1) and a lining (2), and the two are sewn together with stitches. This stitching is intended to prevent the feathers from shifting while the garment is being worn (paragraph

[0032] ).

[0006] In addition, the garment (1) of Patent Document 2 has a feather layer 13 formed between two nonwoven fabrics (12), (14), and similarly, feathers are stitched with an upper thread (31) and a lower thread (32) to prevent the feather layer 13 from moving, and in this case, it is disclosed that the lower thread (32) is a stretchable thread.

[0007] However, all stitches applied to the clothing are intended to fix the position of the feathers sandwiched between two layers of fabric, and although stretchable thread is used in Reference 2, the side on which this stretchable thread (bobbin thread (32)) is arranged is the outer fabric side, and its purpose is to prevent the capillary fibers from escaping from the surface of the outer fabric or the seams (

[0010] step, etc.), and even if it is applied to air-conditioned clothing made of a single piece of fabric and which does not need to contain the feathers, its effect will be different. Summary of the Invention [Problem to be solved by the invention]

[0008] Therefore, the object of the present invention is to provide air-conditioned clothing with expansion-regulating stitching that, when air is taken inside the air-conditioned clothing, regulates the expansion due to the air pressure of the clothing and can properly maintain the contours of the clothing. [Means for solving the problem]

[0009] In order to achieve the above object, the air-conditioning clothing of the present invention has a fan that draws in outside air, and the fabric that forms the outer surface of the air-conditioning clothing has a plurality of parallel stitches at predetermined intervals, using elastic thread on one of the back side or the front side of the fabric and non-elastic thread on the other of the front side or the back side, so that when the fan draws in outside air into the air-conditioning clothing, the expansion of the fabric is evenly distributed among the stitches. At the same time, a stitch-free region where the stitches are not formed is formed in an underarm belt or shoulder belt between the front body and the back body of the air-conditioning garment. It is characterized by: [Effects of the Invention]

[0010] According to the air-conditioned clothing with expansion-regulating stitching of the present invention, stitches are applied to a single piece of fabric that forms the outer surface of the air-conditioned clothing using elastic thread and non-elastic thread, so that the elastic thread forms wrinkles around the stitches that allow for stretch, and when air is taken inside the air-conditioned clothing and the air-conditioned clothing expands, the non-elastic thread keeps the expansion within a predetermined range, so that the expansion of the clothing can be evenly distributed between the stitches and the contours of the air-conditioned clothing are not significantly distorted.

[Figure 4] FIG. 10 is a front view of an air-conditioning garment with expansion-regulating stitching according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] A first embodiment of the present invention will be described with reference to Figures 1 and 2. The overall structure of the air-conditioning garment of this embodiment with expansion-regulating stitching will be described with reference to Figure 1, the function of the stretchable yarn and non-stretchable yarn in the air-conditioning garment will be described with reference to Figure 2, and the function and effect of the air-conditioning garment will be described with reference to Figure 3.

[0013] Fig. 1(a) is a front view of air-conditioned clothing A, and Fig. 1(b) is a back view of air-conditioned clothing A. As shown in these figures, air-conditioned clothing A with expansion-regulating stitching of the present invention has openings on the left and right sides of the waist area on the back of the outer fabric 1 of the clothing, and two fans 2a, 2a, which form the air conditioning unit 2, are attached to these openings, making it possible to take in outside air into the air-conditioned clothing A. In this embodiment, air-conditioned clothing A is a sleeveless vest.

[0014] The air conditioning unit 2 has a battery unit 2b that drives the fan 2a, and the battery unit 2b is stored in a pocket of the air-conditioned clothing A (not shown), and driving power is supplied to the fans 2a, 2a via a cord wired inside the air-conditioned clothing A.

[0015] Additionally, multiple stitches 3 are applied horizontally to the fabric 1a that constitutes the outer fabric 1 of the garment. The stitches 3 are intended to form fine wrinkles in the fabric 1a of the outer fabric 1 of the garment using a structure described below. The stitches 3 are applied to the front portions of the front and back bodies of the air-conditioned garment A at a uniform density per specified area, preventing uneven expansion regulation in the areas where the stitches 3 are formed. The stretch structure will be described later using Figure 2.

[0016] The air-conditioning garment A has a collar 4, and the sides 5a under the armpits and the shoulders 5b on both sides that connect the front body fabric 1a and the back body fabric 1a form stitch-free areas 5 where no stitches 3 are sewn.

[0017] As shown in the back view of the air-conditioned clothing A (Fig. 1(b)), a neck passage 6 is formed from the back to the collar 4, which sends the air inside the air-conditioned clothing A to the nape of the neck. The air-conditioned clothing A has a front opening structure with a zipper 8 to improve airtightness at the front.

[0018] For this reason, when fan 2a is used to introduce outside air into air-conditioned clothing A, no air leaks out because openings 7 at the neck 7a, shoulders and sleeves 7b, and waist 7c of air-conditioned clothing A are in close contact with the wearer's body. As a result, the air taken into the air-conditioned clothing A is expelled through neck flow path 6, effectively cooling the nape of the neck, which is effective in lowering body temperature.

[0019] The function of stitch 3 will be explained using Figure 2. Figure 2(a) shows the state before fan 2a is activated, when no air pressure is applied inside the air-conditioned clothing A, and Figure 2(b) shows the state after fan 2a is activated, when air pressure is applied inside the air-conditioned clothing A.

[0020] The stitch 3 is formed by using a non-elastic thread as the upper thread 31 exposed on the front side 1A of the fabric 1a of the outer garment fabric 1, and an elastic thread as the lower thread 32 exposed on the back side 1B. The lower thread 32 is stretched and sewn together with the upper thread 31 to form the stitch 3.

[0021] 2(a), when the fan 2a is not operating and no air pressure is applied inside the air-conditioned clothing A, the lower thread 32, which is an elastic thread, is in a contracted state, the upper thread 31 is pulled by the lower thread 3 and becomes a loop, and the distance between the joint 33 of the upper thread 31 and the lower thread 32 is reduced. Then, the fabric 1a gathers, forming fine wrinkles W, and the surface area of ​​the air-conditioned clothing A as a whole is in a contracted state.

[0022] On the other hand, when the fan 2a is operated and air pressure is applied to the inside of the air-conditioned clothing A, the elastic lower thread 32 is stretched by the air pressure. As a result, the gap between the joint 33 of the upper thread 31 and the lower thread 32 increases, the wrinkles W0 in the fabric 1a widen, and the surface area of ​​the entire air-conditioned clothing A increases, causing it to expand as a whole.

[0023] At this time, when the loop of the upper thread 31, which is a non-stretchable thread, is fully stretched, it then restricts this expansion, preventing the air-conditioned clothing A from expanding distortedly due to the air pressure.

[0024] The effects of the air-conditioned clothing A will be explained using Figure 3. Figures 3(a) and 3(b) are both side views of the air-conditioned clothing A, with Figure 3(a) showing the state of the air-conditioned clothing before inflation and Figure 3(b) showing the state of the air-conditioned clothing after inflation.

[0025] As shown in Figure 3(a), before the fan 2a is driven, the stitches 3 are shrunk and the shape is similar to that of a normal vest, fitting closely to the body. Next, as shown in Figure 3(b), the fan 2a is driven to take in air into the air-conditioned clothing A, causing it to expand.

[0026] At this time, as described above, the stretchable lower thread 32 of the stitch 3 allows the outer fabric 1 of the garment to expand, but since the stitches 3 are applied at predetermined intervals to the outer fabric 1 of the garment and are formed uniformly per predetermined area, there is no bias in the expansion regulation of the air-conditioned garment A, and it is possible to prevent significant damage to the contours of the air-conditioned garment A.

[0027] Furthermore, the underarm straps 5a and shoulder straps 5b that join the front and back body sections of the air-conditioned clothing A are not stitched 3 and are non-stretchable straps 5 that do not form wrinkles W for stretching, so even when the fan 2a is operated to inflate the air-conditioned clothing A, it is possible to prevent the air-conditioned clothing A from expanding laterally. As a result, the contours of the air-conditioned clothing A can be adjusted when inflated, making it possible to create a vest that is highly fashionable.

[0028] An air-conditioning garment B according to a second embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a front view of the air-conditioning garment B. The same components as those in the first embodiment are given the same reference numerals, and descriptions thereof will be omitted.

[0029] The air-conditioned garment B has multiple stitches 13 that intersect diagonally at predetermined intervals on the fabric 1a of the outer garment fabric 1. As in Fig. 2, the stitches 13 are made of an upper thread that is a non-stretchable thread and a lower thread that is a stretchable thread, and fine wrinkles are formed along the stitches 13 in the outer garment fabric 1.

[0030] Unlike the air-conditioned clothing A of the first embodiment, the air-conditioned clothing B also has stitches 13 formed in the underarm bands 15 on the sides of the air-conditioned clothing B, and this part is also structured to allow expansion as a stitch formation area.

[0031] In the air-conditioned clothing B, the stitches 13 form a large number of rectangular segments (diamond segments) surrounded by the stitches 13 uniformly on the surface of the fabric 1a per specified area, so that when the fan 2a is operated to inflate the air-conditioned clothing B, each of these segments inflates uniformly, and the expansion is restricted after it has inflated a specified amount, so the contours of the air-conditioned clothing B are not significantly damaged.

[0032] As described above, according to the first and second embodiments of the air-conditioned clothing A and B, by selectively providing stitch-formed areas on the surface of the air-conditioned clothing that allow stretching and regulate the amount of expansion, and stitch-free areas that do not allow stretching, at appropriate positions on the air-conditioned clothing, it is possible to control the expansion of the air-conditioned clothing and maintain a beautiful contour.

[0033] (Other embodiments) As explained above, in the air-conditioned clothing A and the air-conditioned clothing B, the stitches 3, 13 are formed using non-stretch yarn on the surface 1A side of the fabric 1a of the outer fabric 1 of the clothing and stretch yarn on the back side 1B side, but the stitch 13 can be formed using a combination of these threads, and it is also possible to use non-stretch yarn on the back side 1B side and stretch yarn on the surface 1A side.

[0034] In the above embodiment, the stitches 3 and 13 are applied to the outer fabric 1 of the garment alone, but a lining may be attached to the fabric 1a as long as it allows for stretching and restricts expansion of the fabric 1a of the outer fabric 1. In particular, it is possible to attach a mesh lining that does not obstruct the flow of air taken in by the fan 2.

[0035] Furthermore, while both air-conditioned clothing A and air-conditioned clothing B are sleeveless vests, they may of course be tops with sleeves, and if the sleeves are long jackets, similar stitching may be applied to the outer fabric of the sleeves to control inflation. Furthermore, the garments using this stitching are not limited to tops, but can also be applied to the outer fabric of trousers. [Explanation of symbols]
