Description

  The present invention relates to shorts, and in particular, to prevent sliding of shorts made of a stretchable material that does not require cleanup.

  The conventional shorts are connected to both sides of the front and back body parts and the front and back body parts and the crotch part by sewing, and elastic tape or the like is sewn to the edge around the base of the waist and thighs. The parts are joined together by sewing. However, there is a problem that the sewn portion increases in thickness and becomes loose, and the touch becomes worse.

  In order to solve the above problem, Japanese Utility Model Registration No. 3136998 (Patent Document 1) proposes shorts using stretchable material that does not require any cleanup. Specifically, as shown in FIG. 3, the waistline 5 and the legline 6 of the shorts 1 are used as cut ends that do not need to be cleaned, and the front and rear body parts 2 and 3 of the shorts 1 are connected via the crotch part 4. At the same time, both side portions 7 of the front and rear body parts 2 and 3 are overlapped and bonded by a thermoplastic resin film 8.

Utility Model Registration No. 3136098

The shorts of Patent Document 1 do not have a sewing portion, and the both sides of the front and back body parts are thinly bonded to each other so that a good touch is easily obtained. However, since there is no holding part such as a rubber band at the upper end, there is a problem that the shorts are likely to slide down.
In the case of a low rise short with a crotch where the upper end of the shorts is located immediately above the hipbone, the upper end of the shorts is caught by the hipbone, so that the sliding can be suppressed to some extent. However, when the rise is deeper than the low rise, the upper end of the shorts only stops at the hipbone position, so the shorts are likely to slide down.

  The present invention has been made in view of the above problems, and the shorts edge including the upper end edge and the underbody edge of the shorts is formed of a stretchable material that does not require cleaning, and a rubber band or the like is attached to the upper end of the shorts. In short shorts, the problem is to reduce the slippage of deep shorts and increase the feeling of wear.

In order to solve the above-mentioned problems, the present invention is such that the front and back body parts are continuous through the crotch part, the both side parts of the front and back body parts are overlapped and fixed with an adhesive, and the upper edge of the waistline and the both sides A shorts made of a stretchable material in which the edge around the leg of the base of the thigh is a cut end that does not require cleaning.
The left and right outer end points of the upper end edge of the waistline are P1 and P2, the outer end points of the left and right leg end edges that are the maximum width portions are P3 and P4, and the side line lines connecting the P1 and P3, P2 and P4, respectively. Are inclined lines close to each other, the inclined lines have an inclination angle of 65 to 80 degrees with respect to the horizontal line S connecting the outer end points P3 and P4, and the lowermost end of the crotch from the front center point P5 of the upper end edge The size L2 from the front center point P5 to the horizontal line S is L2 / L1 of 0.7 to 0.9.

  The shorts of the present invention, as described above, when the dimension from the front center point P5 of the upper edge of the shorts to the bottom end of the crotch is L1, and the dimension from the front center point P5 to the horizontal line S is L2, L2 The dimension / L1 satisfies 0.7 to 0.9. The shorts having such dimensions have a relatively long dimension from the upper end edge to the lowermost end of the crotch part, and the upper end edge is above the hipbone and is close to the waistline, so-called deep soaking type.

Further, as described above, the side line lines that connect the left and right outer end points P1 and P2 located on the left and right side lines of the upper end edge of the shorts and the outer end points P3 and P4 of the left and right leg end edges that become the maximum width portion ( Line segments P1-P3, line segments P2-P4) are inclined lines close to each other upward, and the inclination angle of the inclined line with respect to the horizontal line S connecting the outer end points P3, P4 is 65 degrees to 80 degrees, It is inclined relatively steeply toward. In this way, when the upper end dimension is narrowed and steeply inclined, the human body increases the waistline dimension from the waist side to the lower abdomen, and thus the upper end of the short-sized shorts is less likely to slide down to increase the dimension. In this way, the function of reducing the sliding of the shorts is provided by the inclination angle of the side line of the shorts.
If the inclination angle of the inclined line with respect to the horizontal line S exceeds 80 degrees, the sliding tends to occur. On the other hand, if the inclination angle is less than 65 degrees, the lower abdomen is too tight and the wearing feeling may be deteriorated. The inclination angle of the inclined line with respect to the horizontal line S is more preferably 70 to 75 degrees.

  As described above, in the shorts of the present invention, while forming the elastic material which does not require the end cleaning and attaching the holding material such as a rubber band to the upper end edge to enhance the wearing feeling, the upper end edge to the lowermost end of the crotch part is increased. Even as a deep-wearing type with relatively large dimensions, it is possible to make it difficult to slide down by making the left and right side lines incline sharply toward the upper end.

In the shorts of the present invention, it is preferable that the L1 is 18 cm to 28 cm, the L2 is 15 cm to 22 cm, and the maximum width portion connecting the P3 and P4 is 25 cm to 30 cm.
It should be noted that the commercially available shorts made of a stretchable material that does not require cleansing have a total length L1 of 16 to 17 cm, which is shallower than the shorts of the present invention, and has a maximum width of 29 to 33 cm. It is getting wider. In other words, it is possible to prevent slipping without causing the wearer to feel cramped by making the depth larger and the maximum width smaller than conventional shorts made of stretchable material that does not require cleansing. Even middle-aged and elderly can wear comfortably.
The “bottom end of the crotch”, which is the end point when measuring the dimension L1, means the bottom end of the crotch at the time of wearing, and the vicinity of the center of the crotch when the shorts are arranged in a planar shape. This corresponds to the “bottom end of the crotch”.

  The stretch-free material used for the shorts of the present invention is not particularly limited, but after heat knitting elastic yarn and other yarns are knitted by a spliced yarn, heat fusion processing is performed by heat setting. Examples of the knitted fabric may include a knitted fabric having a fraying prevention function.

  As an adhesive that overlaps and fixes both side portions of the front and back body parts, although not particularly limited, a film-like hot melt adhesive is interposed on the inner surface of the overlapping surface, and the hot melt adhesive is heated with an iron or the like. After melting, it is preferable to cool and solidify and fix the overlapping surfaces of the front and back body parts.

  As described above, according to the present invention, the left and right outer end points P1 and P2 of the upper end edge of the shorts made of a stretchable material that does not require cleaning, and the outer end points P3 and P4 of the left and right leg end edges that become the maximum width portion. The side line lines (line segment P1-P3, line segment P2-P4) are connected to each other, and the inclination angle of the inclined line with respect to the horizontal line S connecting the outer end points P3, P4 is 65 degrees to 80 degrees. Therefore, even as a deep-wearing type that satisfies L2 / L1 = 0.7 to 0.9, it is possible to effectively prevent sliding down and enhance the wearing feeling.

It is a schematic plan view which shows the shorts of this embodiment. It is a general | schematic expanded view which shows the inner surface side of shorts. It is a figure which shows a prior art example.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the shorts 10 of the present embodiment made of a stretchable material that does not require cleanup is formed of a front body part 11, a back body part 12, and a crotch part 13. The body part 12 is continuous through the crotch part 13 and the upper edge E1 around the waist and the leg edge E2 at the base of the thighs on both sides are used as cut ends that do not require any cleanup.

  In the cut fabric as shown in FIG. 2, a patch cloth 15 slightly narrower than the crotch part 13 is disposed on the inner surface side of the crotch part 13, and the patch cloth 15 and the crotch part 13 are fixed by the hot melt adhesive 14. is doing. In the present embodiment, a film-like hot melt adhesive 14 is interposed at the periphery of the patch cloth in contact with the crotch portion 13, and the hot melt adhesive 14 is melted by heating and pressing with an iron or the like, and then cooled and solidified. Thus, the crotch portion 13 and the batter 15 are fixed.

  Furthermore, both the side portions 11a and 11b of the front body portion 11 and the both side portions 12a and 12b of the back body portion 12 are overlapped, and the hot melt is formed between the overlapped side portions 11a and 12a and between the overlapped side portions 11a and 12b. The overlapped side portions 11a, 12a and 11b, 12b are respectively fixed by the same method as the fixing of the crotch portion 13 and the patch cloth 15 with the adhesive 14 interposed therebetween.

  As the stretchable material used for the front and rear body parts 11 and 12, the crotch part 13, and the application cloth 15, heat-set elastic yarns and other yarns are knitted by a spliced yarn and then heat set A knitted fabric provided with a function to prevent fraying by melting a heat-sealed elastic yarn by processing. Examples of the knitting yarn include cotton, rayon, polyester, nylon, and cupra.

  The shorts 10 of the present embodiment shown in FIG. 1 has P1 and P2 as the left and right outer end points of the upper edge E1 around the waist, and P3 and P4 as the outer end points of the left and right leg periphery edges that become the maximum width portion. In the present embodiment, the side line lines (line segment P1P3, line segment P2P4) connecting P1 and P3 and P2 and P4, respectively, are inclined lines that are close to each other upward, and the inclined line has outer end points P3 and P4. The inclination angle is 65 to 80 degrees with respect to the connecting horizontal line S. Further, when the dimension from the front center point P5 of the upper end edge E1 of the shorts 10 to the lowest end point P6 of the crotch is L1, and the dimension from the front center point P5 to the horizontal line S is L2, L1 is 20 cm to 26 cm. , L2 is 17 cm to 19 cm, and L2 / L1 is 0.7 to 0.9. Further, the maximum width L3 connecting the P3 and P4 is set to 25 cm to 29 cm. In addition, the lowest end point P6 of the crotch part 13 is the center position of the crotch part 13 when the shorts 10 is arranged on a plane.

  As described above, the left and right outer end points P1 and P2 of the upper end edge of the shorts 10 made of an elastic material that does not require end care and the outer end points P3 and P4 of the left and right leg end edges that become the maximum width portion are respectively connected. Line lines (line segment P1-P3, line segment P2-P4) are inclined lines close to each other, and the inclination angle of the inclined line with respect to the horizontal line S connecting the outer end points P3, P4 is defined as 65 degrees to 80 degrees. Therefore, even if it is a deep-wearing type in which L2 / L1 is 0.7 to 0.9, it is possible to effectively prevent sliding down and enhance the wearing feeling.

  In addition, L1 is 20 cm to 26 cm, L2 is 17 cm to 19 cm, the maximum width L3 connecting P3 and P4 is 25 cm to 29 cm, and the depth is larger than conventional shorts made of stretchable material that does not require cleansing, and Since the maximum width is made smaller, the sliding can be prevented without causing the wearer to feel cramped.

Hereinafter, the present invention will be described in detail by Examples 1 and 2 and Comparative Examples 1 and 2.
[Example 1]
In Example 1, in the shorts according to the above-described embodiment, the elastic material that does not require cleansing is made by knitting a low melting point polyurethane elastic yarn and a nylon yarn with a knitting yarn, and then heat-setting the low melting point polyurethane elastic yarn. The knitted fabric is melted and provided with a fray-preventing function, and the inclination angle of the inclined lines (line segments P1-P3, line segments P2-P4) with respect to the horizontal line S connecting the outer end points P3, P4 is set to 75 degrees, and L1 Was 20 cm, L2 was 17 cm, the maximum width L3 connecting P3 and P4 was 27 cm, and L2 / L1 was 0.85.
[Example 2]
In Example 2, in the shorts according to the above-described embodiment, the stretchable material that does not require cleansing is made by knitting a low-melting polyurethane elastic yarn and a cotton yarn with a knitted yarn, and then melting the low-melting polyurethane elastic yarn by heat setting. The knitted fabric is provided with a fray-preventing function, and the inclination angle of the inclined line (line segment P1-P3, line segment P2-P4) with respect to the horizontal line S connecting the outer end points P3, P4 is 73 degrees, and L1 is 26 cm, L2 was 19 cm, the maximum width L3 connecting P3 and P4 was 29 cm, and L2 / L1 was 0.73.

[Comparative Example 1]
Comparative Example 1 was the same as Example 1 except that the inclination angle of the inclined lines (line segment P1-P3, line segment P2-P4) with respect to the horizontal line S connecting the outer end points P3 and P4 was 83 degrees.
[Comparative Example 2]
Comparative Example 2 was the same as Example 1 except that the inclination angle of the inclined lines (line segment P1-P3, line segment P2-P4) with respect to the horizontal line S connecting the outer end points P3 and P4 was 62 degrees.

In the deep-pants type shorts of Example 1 and Example 2, L2 / L1 is 0.7 to 0.9, and an inclined line (line segment P1-P3, line with respect to the horizontal line S connecting the outer end points P3 and P4 is used. Since the inclination angles of the minutes P2 to P4) are in the range of 65 degrees to 80 degrees, respectively, it is possible to effectively prevent sliding down and enhance the wearing feeling.
On the other hand, in the short-sleeved shorts of Comparative Example 1, even if L2 / L1 is set to 0.7 to 0.9, an inclined line (line segment P1-P3, line segment P2-) with respect to the horizontal line S connecting the outer end points P3 and P4. Since the inclination angle of P4) exceeds 80 degrees, sliding down occurred and the wearing feeling deteriorated. In addition, in the deep-pants type shorts of Comparative Example 2, even if L2 / L1 is set to 0.7 to 0.9, an inclined line (line segment P1-P3, line segment P2-) with respect to the horizontal line S connecting the outer end points P3 and P4. Since the inclination angle of P4) was less than 65 degrees, the lower abdomen was too tight and the wearing feeling deteriorated.
