Example 1
As shown in FIGS. 1 to 3, the fall protection lower body garment P according to the first embodiment of the present invention includes a garment main body 1 that is a main component of the fall protection lower body garment P.

  The garment main body 1 according to Example 1 is stretchable knitted with fibers (in this example, Sophista (registered trademark) manufactured by Kuraray Co., Ltd.) formed by coating polyester fiber yarns with ethylene-polyvinyl copolymer fiber yarns. Made of fabric.

  The clothing main body 1 according to the first embodiment includes a right piece fabric 10 and a left piece fabric 11 which are constituent members. After cutting the right piece fabric 10 and the left piece fabric 11, respectively, the stretch reduction part 13 is formed, and then the right piece fabric 10 and the left piece fabric 11 are opposed to each other, and the opposite side portions and lower end portions are stitched together. And unite. As described above, the garment main body 1 itself according to the first embodiment is configured as a single piece, not a double cloth.

  On the inner side of the entire circumference of the upper end 14 of the garment main body 1, an elastic waist tie band 5 for preventing the waist 12 from sliding down is sewn inside the fabric. The waist band 5 is a means for preventing the waist 12 from sliding down as in the case of general lower body clothing, and does not correct the pelvis.

  The stretch reduction part 13 is provided in a belt-like shape having a width of 60 mm to 80 mm within the entire circumference from the abdomen to the waist, with the upper limit being approximately 30 mm to 40 mm below the upper end of the clothing main body. The stretch reduction part 13 is formed by high-temperature pressurization by a hot press means. The stretch reduction part 13 in a present Example is formed by performing the hot press for 30 second at 170 degreeC.

  By heat pressing, the surface of the stretch reduction part 13 melts the ethylene-polyvinyl copolymer fiber yarn in the constituent fibers of the fabric and fuses it with other adjacent ethylene-polyvinyl copolymer fiber yarns. The entanglement point increases, resulting in a decrease in stretchability.

  That is, the configuration of the invention according to Example 1 is partially softened and finely glued when the ethylene-polyvinyl copolymer fiber yarn is heated as disclosed in Citation 5, etc. It is not an extreme physical property that deteriorates, but a slightly and uniformly cured portion is formed within the entire circumference from the abdomen to the waist of the garment. The rate can be controlled within the range of about 30 to about 95%, and the pelvis can be corrected by making a full circle around the waist. And the elasticity of a stretch reduction part is not a hard thing, and the stretchability and the touch reduced by the range suitable as an underwear or sportswear can be maintained to the last.

  Moreover, since the stretch reduction part 13 is formed of the same piece of fabric as the adjacent part, there is almost no step difference. For this reason, a wearer does not give a sense of incongruity, and a step is not formed in the appearance of the outer layer to be layered.

  This makes it possible to realize a pelvic correction means by the stretchability reducing unit at a very low cost, and the correction means can stabilize the posture and walking, and can prevent falls.

(Example 2)
As shown in FIGS. 4 to 12, the fall protection lower body garment P according to the second embodiment of the present invention is an improvement of the fall protection lower body garment P according to the first embodiment, and the fall protection lower body garment according to the first embodiment. In addition to the structure of the clothing P, the protective pad 2 for protecting the iliac 91 and the greater trochanter 90 is provided.

  The fall protection lower body garment P according to the second embodiment includes a garment main body 1 and a polyurethane protection pad 2.

  As shown in FIGS. 4 to 6 and 14, the garment main body 1 is a fiber formed by coating the same polyester fiber yarn as in Example 1 with an ethylene-polyvinyl copolymer fiber yarn (Sofista (registered by Kuraray Co., Ltd.)). And a pad storage bag 16 formed of a protective pad storage fabric for storing the protective pad 2.

  After the right piece fabric 10, the left piece fabric 11, and the two protective pad storage fabrics are cut from the fabric, the stretch reduction part 13 is formed in the right piece fabric 10 and the left piece fabric 11. Thereafter, only the edge of the protective pad storage fabric is sewn to the clothing main body 1 from the surface side. In this state, the right piece fabric 10 and the left piece fabric 11 are opposed to each other, and the opposite side portions and the lower end portion are stitched together to form the fall protection lower body garment according to the second embodiment.

  The pad storage bag 16 according to the second embodiment is provided with an opening / closing part 15 for storing and taking out the protective pad 2. A slide fastener 150 that can be operated from the outside of the fabric is used for the opening / closing part 15. The slide fastener 150 is covered with two covering pieces 151 provided in parallel with each other along the rail of the slide fastener 150 so as not to be exposed to the outside.

  As shown in FIGS. 7 to 12, the protective pad 2 according to the second embodiment sandwiches the urethane foam layer 20 between two outer fabrics 21, and covers the entire periphery of the edge of the urethane foam layer 20 and the outer fabric 21. It is formed by hot pressing. The iliac protection part 22 and the greater trochanter protection part 23 are integrally provided, and a notch part 24 and a narrow neck part 25 are provided between the iliac protection part 22 and the greater trochanter protection part 23 in plan view. It is the formed structure. A thin edge 26 in the range of about 4 mm to 8 mm from the edge is formed by hot pressing on the entire periphery of the edge. While the thin edge portion 26 has flexibility, it functions to keep the shape of the protective pad 2 constant, so that the protective pad 2 having the iliac protective portion 22 and the greater trochanter protective portion 23 that are flexible and easily deformed is opened and closed. When inserting into or removing from the unit 15, the operation can be facilitated.

The neck portion 25 has a width of about 15 mm, and the width occupied by the urethane foam layer 20 is about 5 mm. For this reason, the neck part 25 is very flexible and can be freely bent, for example, not only in the direction in which the protective pad 2 is folded but also in the direction in which the space of the notch part 24 is filled. Since the degree of freedom is thus high, the orientation of the iliac 91 and the greater trochanter 90 can be changed flexibly, so that the body can be protected flexibly along the iliac 91 and the greater trochanter 90.

  Next, with respect to the formation of the stretchability reducing portion 13 in the present invention, the following test was performed to confirm the effectiveness.

For a fabric made of a fiber (Sofista (registered trademark) manufactured by Kuraray Co., Ltd.) obtained by coating the polyester fiber yarn used in this example with an ethylene-polyvinyl copolymer fiber yarn, 5 test pieces were placed in the vertical direction, and the test piece 5 Using a tensile tester in the horizontal direction, one end of the test piece is clamped, the initial load is applied to the other end, the test piece is marked at regular intervals, and a constant load is applied for one minute. The length between marks after standing was measured, and the constant load elongation (%) of the fiber was calculated (according to JIS L 1018 cut strip method). The test strip width of the cut strip method was 5 cm, the holding interval was 10 cm, and the constant load was 9.81 N. Moreover, the low load elongation rate was 100 (%) × (L ₁ −L) / L. Here, L is the length (cm) between the original marks by the cut strip method, and L ₁ is a measured value between the marks after applying a constant load.
The results are shown in Table 1 below.

  From the above results, only by raising the temperature in increments of only 10 ° C., a large difference in the constant load elongation occurred and the physical properties became very different.

  On the other hand, although not described in Table 1 above, there was almost no change in physical properties at 170 ° C. for less than 30 seconds compared to those without thermal processing. On the other hand, when the temperature exceeded 190 ° C. for 30 seconds, the polyester yarn in the fiber was cured, and the quality was significantly reduced.

  From the above, physical properties suitable for pelvic correction can be realized by heating for about 30 seconds in the range of approximately 170 ° C. to 190 ° C.

  Even within the range of 170 ° C. to 190 ° C., increasing the temperature only in increments of 10 ° C. produces a large difference in the constant load elongation rate, resulting in very different physical properties. In the invention, by utilizing the difference in physical properties resulting from this heating temperature condition, low load elongation rate according to each demand, such as those who need strong tightening force for pelvic correction and those who need weak tightening force enough It is possible to provide a fall-protective lower body garment that adjusts the above. For example, in Examples 1 and 2, although the heating condition is 170 ° C. for 30 seconds, the present invention is not limited to this. For example, by setting the heating condition to 190 ° C. for 30 seconds, the low load elongation is further reduced, It is possible to provide a fall-protective half-body garment that can be more strongly corrected by the wearer.

  In addition, although the heating part by a hot press shall heat the whole surface, this invention is not limited to the said structure. For example, as shown in FIG. 15 as another embodiment, a heated portion by hot pressing can be partially hot pressed as a pattern outline 17 such as a polka dot pattern or a star shape.

  In particular, by performing partial hot pressing such as a polka dot pattern or the like, it is possible to perform adjustment to suppress the degree of reduction in stretchability by ensuring stretchability of a portion where hot pressing is not performed.

  Moreover, although the opening / closing part 15 in the fall protection lower body garment P according to the second embodiment uses the slide fastener 150, the present invention is not limited to this, and other known engaging means, for example, The male and female snap buttons, buttons and button holes, male and female surface fasteners, and the like can be used.

  Furthermore, the protective pad 2 used for the fall protection lower body garment according to the second embodiment is not limited to the second embodiment. For example, as shown in FIG. 17 as the protective pad 2 according to another embodiment, A plurality of notches 24 may be owned.

  Further, as shown in FIGS. 18A and 18B, the protective pad 2 can be configured to have a two-layer structure in which the outer surface side is made of low-repulsion urethane 20a and the inner surface side is made of high-repulsion urethane 20b. By adopting such a configuration, the impact from the outer surface side is reduced by the low-resilience urethane 20a, the direct impact on the wearer is absorbed by the high-resilience urethane 20b disposed on the inner surface side, and the hip joint is more sufficiently protected. Can be. The protective pad 2 having the two-layer structure may be further covered with the outer fabric 21 in the same manner as the protective pad 2 disclosed in the first and second embodiments.
