Description

[Technical Field]

[0001] The present invention relates to breathable pants, and more particularly to breathable pants that can be ventilated at the rear waist area of ​​the pants as needed. [Background technology]

[0002] A known example of a garment that uses a blower to blow air into the garment and then toward the neck and armpits of a wearer to cool the neck and armpits is the garment described in Patent Document 1 below. This garment has an internal space between the outer and inner bodies of the garment, and air is blown into the internal space by a blower provided in the outer body and then ejected toward the wearer's neck and armpits through guide openings provided in the inner body. With this garment, air blown in by a blower provided in the lower part of the outer body can be reliably guided to guide openings provided in the upper part of the inner body, thereby enabling the wearer's neck and armpits to be air-cooled accurately.

[0003] However, the garment described in Patent Document 1 was not designed to send air into the trousers using an air blower attached to the jacket, and had the drawback of not being able to air-cool the wearer's lower body.

[0004] To date, the following Patent Document 2 has proposed air-conditioning wear that can simultaneously cool not only the upper body but also the lower body of the wearer using a blower attached to the jacket.

[0005] However, the air-conditioning wear described in Patent Document 2 has a fitting part at the top of the pants that fits tightly around the waist of the wearer, and a simple ventilation part below this fitting part, which basically opens in the front and back directions. Therefore, as shown in Figure 8(b) of Patent Document 2, when the bottom end (hem) of the jacket equipped with a blower is fitted tightly from the outside to the pants below the ventilation part, depending on the degree of fitting, it is not possible to ensure a sufficient gap between the pants and the wearer in the ventilation part and the area below it, resulting in insufficient air cooling of the lower half of the body.

[0006] Furthermore, the air-conditioning wear pants described in Patent Document 2 have ventilation sections that are always open, which means that the ventilation inside the pants cannot be stopped even when the wearer does not want air to cool the lower half of their body, for example when working in winter.

[0007] [Patent Document 1] Patent No. 6502033 [Patent Document 2] Patent No. 6827482 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention was made in consideration of the above-mentioned drawbacks of conventional breathable trousers, and its object is to provide breathable trousers that can effectively ventilate the rear waist area of ​​the trousers as needed.

[0009] Another object of the present invention is to provide breathable trousers that can effectively send air from a ventilator attached to a conventionally known jacket into the trousers, thereby cooling the lower half of the wearer's body, even when the wearer is wearing such a jacket. [Means for solving the problem]

[0010] The present invention is a pair of trousers having a waist portion that surrounds the wearer's torso and front and back portions that cover the wearer's lower body, characterized in that an openable and closable ventilation opening that opens in the vertical direction is provided between the rear of the waist portion and the upper part of the back portion.

[0011] The present invention is also characterized by comprising opening means for opening the ventilation opening and closing means for closing the ventilation opening.

[0012] The present invention is also characterized in that the opening means comprises a flexible band-like body arranged approximately horizontally between the rear of the waistband and the upper part of the back body, and the ventilation opening is opened by curving the longitudinal center portion of the band-like body in a convex shape toward the rear more than the rear of the waistband and the upper part of the back body.

[0013] Furthermore, the present invention provides a garment in which the opening means comprises a right string-like body having a base end attached to a position to the left of the longitudinal center of the band-like body and a tip end extending beyond the longitudinal center of the band-like body to the right side of the waist part; a right opening fastening part attached to the right side of the waist part and for detachably fastening the tip end of the right string-like body; a left string-like body having a base end attached to a position to the right of the longitudinal center of the band-like body and a tip end extending beyond the longitudinal center of the band-like body to the left side of the waist part; and a left opening fastening part attached to the left side of the waist part and for detachably fastening the tip end of the left string-like body; The distal end of the right string-like body and the distal end of the left string-like body are engaged with the right opening engaging portion and the left opening engaging portion, respectively, thereby shortening the distance between the base end of the right string-like body and the base end of the left string-like body and curving the band-like body.

[0014] The present invention also provides a seat belt comprising a right guide provided at a position to the right of the rear center of the waist portion and through which the band-like body is inserted, and a left guide provided at a position to the left of the rear center of the waist portion and through which the band-like body is inserted, When the tip end of the right string-like body and the tip end of the left string-like body are engaged with the right opening engagement portion and the left opening engagement portion, respectively, the right guide causes the band-like body to bend convexly forward between the longitudinal center of the band-like body and the right side portion, and the left guide causes the band-like body to bend convexly forward between the longitudinal center of the band-like body and the left side portion.

[0015] The present invention is also characterized in that a hook having a downward groove is provided at the rear of the waistband portion. [Effects of the Invention]

[0016] The breathable pants of the present invention have an openable and closable ventilation opening that opens in the vertical direction between the rear of the waistband and the upper part of the back body, so that ventilation inside the pants can be effectively achieved as needed.

[0017] Furthermore, even when wearing a conventional jacket equipped with a blower, the air blown by the blower provided in the jacket can be effectively sent into the trousers, allowing the lower half of the wearer's body to be sufficiently cooled. [Brief explanation of the drawings]

[0019] As shown in Figure 1, the breathable pants 10 of this embodiment are composed of a waist portion 1 that surrounds the entire torso of the wearer, and a front body portion 2 and a back body portion 3 that cover the lower half of the wearer's body.As shown in Figure 2, an openable and closable ventilation opening 4 that opens in the vertical direction is provided between the rear of the waist portion 1 and the upper part of the back body portion 3.

[0020] A front opening 11 that can be opened and closed by a slide fastener (not shown) is formed at the front of the waistband 1 and the front body 2. As the opening and closing means for the front opening 11, in addition to the slide fastener, for example, a clasp such as a snap, a button, a hook, etc. can be used as appropriate.

[0021] The outer surface of the upper part of the waist portion 1 is provided with a plurality of belt loops 12, and the breathable trousers 10 can be worn by fastening a belt 13 that is passed through the plurality of belt loops 12 and wrapped around the outer surface of the waist portion 1. In addition, elastic portions 14 lined with rubber or the like are formed on the left and right sides of the upper part of the waist portion 1, and each elastic portion 14 can be elastically stretched or contracted as needed.

[0022] In the breathable trousers 10 of this embodiment, the upper part of the front body 2 is joined to the front part of the waistband 1, while the upper part of the back body 3 is separate and not joined to the waistband 1. As a result, as shown in FIG. 2, when the upper part of the back body 3 is moved backward, a vertically opening 4 is formed between the rear part of the waistband 1 and the upper part of the back body 3. The front edge of the back body 3, except for its upper part, is joined to the rear edge of the front body 2. In FIG. 2, the reference numeral 31 indicates a gusset portion provided between the front body 2 and the back body 3. A hook 7 having a downward groove 71 is provided on the upper rear surface of the back body 3. This hook 7 may be attached to and detached from the back body 3.

[0023] Furthermore, as shown in Figure 1, the ventilation pants 10 of this embodiment are configured so that when the upper part of the back body 3 is moved forward, the ventilation opening 4 can be closed, and at this time, the upper part of the back body 3 overlaps the upper part of the waist area 1.

[0024] The breathable pants 10 of this embodiment also include opening means 5 for reliably opening the ventilation openings 4, and closing means 6 for reliably closing the ventilation openings 4.

[0025] As shown in Figures 3 and 4, the opening means 5 is composed of: a flexible band-like body 51 arranged approximately horizontally between the rear of the waist portion 1 and the upper part of the back body 3; a right string-like body 52 having a base end attached to a portion 51L to the left of the longitudinal center of the band-like body 51 and a tip end extending beyond the longitudinal center of the band-like body 51 to the right side of the waist portion 1; a right opening fastening portion 53 arranged on the right side of the waist portion 1 and detachably fastening the tip end of the right string-like body 52; a left string-like body 54 having a base end attached to a portion 51R to the right of the longitudinal center of the band-like body 51 and a tip end extending beyond the longitudinal center of the band-like body 51 to the left side of the waist portion 1; and a left opening fastening portion 55 arranged on the left side of the waist portion 1 and detachably fastening the tip end of the left string-like body 54.

[0026] The belt-like member 51 of this embodiment is made of a narrow woven fabric such as a nylon belt, and is provided between the waist portion 1 and the back body portion 3 with its longitudinal direction being approximately horizontal.

[0027] In this embodiment, the band 51 has its longitudinal center inserted into a short cylindrical center guide 32 provided on the front of the rear center of the back body 3, and between the longitudinal center of the band 51 and the right region 51R, the band 51 is inserted into a short cylindrical right guide 16 provided on the outer surface of a region 15R of the waist region 1 to the right of the rear center, and the band 51 is inserted and fixed from the right region 51R to the right end inside the back body 3. Furthermore, the band 51 is inserted into a short cylindrical left guide 17 provided on the outer surface of a region 15L of the waist region 1 to the left of the rear center, between the longitudinal center of the band 51 and the left region 51L, and the band 51 is inserted and fixed from the left region 51L to the left end inside the back body 3.

[0028] In this embodiment, the right string-like body 52 and the left string-like body 54 are made of a soft, narrow woven fabric that is smaller in width and thickness than the belt-like body 51, and are arranged between the waist area 1 and the back body 3 with their longitudinal direction approximately horizontal.

[0029] In this embodiment, the base end of the right string-like body 52 is sewn and fixed to the left side portion 51L of the band-like body 51 together with the back body 3, and between the base end and the tip end of the right string-like body 52, it is inserted in this order into the left guide 17, the right guide 16, and the short cylindrical right auxiliary guide 33 provided on the inner surface near the right front edge of the back body 3.

[0030] Similarly, in this embodiment, the base end of the left string-like body 54 is sewn and fixed to the right side portion 51R of the band-like body 51 together with the back body 3, and between the base end and the tip end of the left string-like body 54, it is inserted in this order into the right guide 16, the left guide 17, and the short cylindrical left auxiliary guide 34 provided on the inner surface near the left front edge of the back body 3.

[0031] The right opening locking portion 53 and the left opening locking portion 55 of this embodiment are composed of known male-female fitting fasteners. That is, as shown in Fig. 3, the right opening locking portion 53 is composed of a male locking member 531 attached to the tip of the right string-like body 52 and a female locking member 532 attached to the outer surface of the right side of the waist portion 1 and releasably fitted with the male locking member 531. Similarly, the left opening locking portion 55 is composed of a male locking member 551 attached to the tip of the left string-like body 54 and a female locking member 552 attached to the outer surface of the left side of the waist portion 1 and releasably fitted with the male locking member 551.

[0032] As the right opening engaging portion 53 and the left opening engaging portion 55, in addition to male-female interlocking fasteners, for example, well-known male-female hook-and-loop fasteners, buttons and buttonholes, etc. may be appropriately used.

[0033] As shown in Figure 4, the closure means 6 is composed of a string-like body 61 whose base end is fixed to the right front edge of the upper part of the back body 3, a right closure locking part 62 that detachably locks the tip end of the string-like body 61, a string-like body 63 whose base end is fixed to the left front edge of the upper part of the back body 3, and a left closure locking part 64 that detachably locks the tip end of the string-like body 63.

[0034] The right closure locking portion 62 and the left closure locking portion 64 of this embodiment are composed of known male-female fitting fasteners. That is, the right closure locking portion 62 is composed of a male locking member 621 attached to the tip of the string-like body 61 and the female locking member 532 that detachably fits with the male locking member 621. Similarly, the left closure locking portion 64 is composed of a male locking member 641 attached to the tip of the string-like body 63 and the female locking member 552 that detachably fits with the male locking member 641.

[0035] In this manner, in this embodiment, the female locking members (532, 552) of the right opening locking portion 53 and the left opening locking portion 55 of the opening means 5 described above are also used as the female locking members of the right closure locking portion 62 and the left closure locking portion 64 of the closure means 6, thereby reducing the number of parts of the breathable trousers 10 and improving the ease of opening and closing the ventilation opening 4. Note that as the right closure locking portion 62 and the left closure locking portion 64, in addition to male-female mating fasteners, well-known male-female hook-and-loop fasteners, buttons and buttonholes, etc. may be used as appropriate.

[0036] 3, by pulling the tip of the right string 52 and the tip of the left string 54 of the opening means 5 forward and fastening them to the right opening fastening portion 53 and the left opening fastening portion 55, respectively, the distance between the base end of the right string 52 and the base end of the left string 54 can be shortened to shorten the linear distance between the left side portion 51L and the right side portion 51R of the band 51, and the vicinity of the longitudinal center portion of the band 51 can be curved rearward in a convex shape more than the rear portion of the waist portion 1 and the upper part of the back body piece 3. In other words, the curvature of the rear convex curved portion of the longitudinal center portion of the band 51 can be made greater than the curvature of the waist portion 1 and the rear portion of the back body piece 3.

[0037] Thus, according to the breathable pants 10 of this embodiment, the band-shaped body 51 provided between the waist portion 1 and the back body 3 is curved in an arch shape with a greater curvature than the waist portion 1 and the back body 3, thereby reliably moving the upper part of the back body 3 rearward relative to the waist portion 1, and reliably forming a ventilation opening 4 that opens in the vertical direction between the rear of the waist portion 1 and the upper part of the back body 3, thereby allowing effective ventilation inside the pants.

[0038] Furthermore, with the breathable pants 10 of this embodiment, when the tip of the right string 52 and the tip of the left string 54 of the opening means 5 are fastened to the right opening fastening portion 53 and the left opening fastening portion 55, respectively, the right guide 16 provided on the waist portion 1 causes the band 51 to bend convexly forward between its longitudinal center portion and the right side portion 51R, and simultaneously the left guide 17 causes the band 51 to bend convexly forward between its longitudinal center portion and the left side portion 51L. This allows the ventilation opening 4 to be opened more reliably.

[0039] Furthermore, since these right guide 16 and left guide 17 are provided on the waist area 1, it is possible to effectively prevent the back body 3 from slipping down relative to the waist area 1, particularly when opening and closing the ventilation opening 4.

[0040] Furthermore, according to the breathable trousers 10 of this embodiment, the band-shaped body 51 is curved in an arch shape between the waist area 1 and the back body 3 to form vertical ventilation openings 4. Therefore, as shown in FIG. 5, even when the wearer M is wearing a known jacket 8 with an air blower, the air A blown by the air blower 81 attached to the jacket 8 can be effectively sent into the trousers, and the lower half of the wearer M's body can be sufficiently air-cooled.

[0041] In conventional blower-equipped jackets 8, the hem 82 is typically tightened elastically with an internal rubber material or adjustable with an inserted string to prevent air A from leaking from the hem 82. In the breathable trousers 10 of this embodiment, the ventilation opening 4 is formed by the arch structure of the band 51. Therefore, even if an external force F is applied from behind to the upper part of the back body 3, the hem 82 of conventional blower-equipped jackets 8 does not easily collapse the ventilation opening 4, which opens vertically, and the air A from the blower 81 can be effectively sent into the trousers. Furthermore, the ventilation opening 4 does not easily collapse when the wearer M bends forward.

[0042] Furthermore, the breathable pants 10 of this embodiment are provided with a hook 7 having a downward groove 71 at the upper part of the back body 3, so that the hem 82 of the fan-equipped jacket 8 can be hooked onto the hook 7, effectively preventing the hem 82 of the jacket 8 from slipping up relative to the back body 3, even when the wearer M bends forward, for example.

[0043] 4, with the breathable trousers 10 of this embodiment, by releasing the retaining ends of the right and left strings 52, 54 of the opening means 5 and pulling the strings 61, 63 of the closure means 6 forward to retain them in the right and left closure retaining portions 62, 64, respectively, the curve of the band 51 can be returned to approximately the same curvature as the waist portion 1 and the back body 3, while the upper part of the back body 3 can be easily moved forward, thereby reliably closing the ventilation opening 4. This reliably stops ventilation through the trousers.

[0044] As described above, the breathable trousers 10 of this embodiment are provided with the opening means 5 and the closing means 6, so the wearer can start and stop ventilation at the rear waist area of ​​the trousers as needed. Therefore, even when the wearer does not want air to cool the lower half of the body, for example, when working in winter, the breathable trousers 10 of this embodiment can be used with the ventilation openings 4 closed, making them suitable for use all year round.

[0045] In the breathable pants 10 of this embodiment, the right string 52 and left string 54 and the right opening fastening portion 53 and left opening fastening portion 55 of the opening means 5 may be equipped with a length adjustment mechanism, such as a well-known movable hook or ladder lock. If the right string 52 and left string 54, etc. are equipped with a length adjustment mechanism, the opening degree of the ventilation opening 4 can be easily adjusted by adjusting the lengths of the right string 52 and left string 54, etc. Furthermore, the strings 61 and 63 and the right closure fastening portion 62 and left closure fastening portion 64 of the closure means 6 may be equipped with a length adjustment mechanism.

[0046] Although the breathable pants 10 of this embodiment have been described above, the present invention can also be implemented in other embodiments.

[0047] For example, as in the breathable pants 20 shown in Figure 6, the opening means 8 for opening the ventilation opening 4 may be composed of a flexible band 81 arranged approximately horizontally between the rear of the waist region 1 and the upper part of the back body 3, a right opening fastening part 82 arranged to the right of the rear center of the waist region 1 and for detachably fastening the right end of the band 81, and a left opening fastening part 83 arranged to the left of the rear center of the waist region 1 and for detachably fastening the left end of the band 81.

[0048] According to these breathable pants 20, the right and left ends of the band 81 are fastened to the right opening fastening portion 82 and the left opening fastening portion 83, respectively, and the linear distance between the right and left ends of the band 81 is made shorter than the length of the band 81 itself, so that the area near the longitudinal center of the band 81 can be curved convexly backward more than the rear of the waist portion 1 and the upper part of the back body 3, and a ventilation opening 4 that opens in the vertical direction can be formed between the rear of the waist portion 1 and the upper part of the back body 3.

[0049] Also, as shown in Figure 6, the right opening engaging portion 82 of the opening means 8 may be composed of a male hook-and-loop fastener member 821 provided at the right end of the band-shaped body 81 and a female hook-and-loop fastener member 822 provided on the rear outer surface of the waist portion 1 and removably joined to the male hook-and-loop fastener member 821, and similarly, the left opening engaging portion 83 may be composed of a male hook-and-loop fastener member 831 provided at the left end of the band-shaped body 81 and a female hook-and-loop fastener member 832 provided on the rear outer surface of the waist portion 1 and removably joined to the male hook-and-loop fastener member 831.

[0050] According to these breathable pants 20, the degree of opening of the ventilation opening 4 can be easily adjusted by changing the joining position of the male hook-and-loop fastener members (821, 831) relative to the female hook-and-loop fastener members (822, 832). Note that instead of male and female hook-and-loop fasteners, for example, buttons and a plurality of buttonholes for engaging with the buttons may also be used as the right opening locking portion 82 and the left opening locking portion 83.

[0051] 7, opening and closing means 9 may be provided for opening and closing the ventilation openings 4 as needed. This opening and closing means 9 is composed of a male hook-and-loop fastener member 91 provided on the right front edge of the upper part of the back body 3, a female hook-and-loop fastener member 92 provided on the right side of the waist area 1 and releasably joined to the male hook-and-loop fastener member 91, a male hook-and-loop fastener member 93 provided on the left front edge of the upper part of the back body 3, and a female hook-and-loop fastener member 94 provided on the left side of the waist area 1 and releasably joined to the male hook-and-loop fastener member 93.

[0052] According to these breathable pants 30, the ventilation opening 4 can be easily opened and closed by changing the joining position of the male hook-and-loop fastener members (91, 93) relative to the female hook-and-loop fastener members (92, 94) of the opening and closing means 9, and the degree of opening of the ventilation opening 4 can also be adjusted. Note that, in addition to the male and female hook-and-loop fastener, the opening and closing means 9 may also be, for example, a button and a plurality of buttonholes for engaging the button.

[0053] The present invention may be embodied in various other forms, including improvements, modifications, and variations based on the knowledge of a person skilled in the art, without departing from the spirit of the invention. Furthermore, within the scope of producing the same action or effect, any of the features specifying the invention may be substituted with other technology, and an integrally configured feature of the invention may be composed of multiple components, or an integrally configured feature of the invention consisting of multiple components may be embodied.
