  Next, preferred embodiments according to the present invention will be listed and described in detail based on the drawings.

  First, the configuration of a muscle strength training support band 1 according to the present embodiment will be described with reference to FIGS. 1 to 6.

  The muscle strength training support band 1 uses a belt-like elastic stretchable member 2 as a basic component. When manufacturing this elastic stretchable member 2, in addition to the fiber thread material 3 used in the width direction Fw and the longitudinal direction Fv as shown in the schematic view in FIG. 2, a plurality of rubber threads arranged in the width direction Fw By sewing the parts 4... Together, it is possible to obtain the desired elastic stretchable member 2. The elastic stretchable member 2 is in the form of a flat band, and can be elastically stretched at least in the longitudinal direction Fv.

  In this case, although various fiber materials including a synthetic fiber material excellent in strength (tensile strength) and shape stability and a natural fiber material can be used as the fiber yarn material 3, it is excellent in strength (tensile strength) and shape stability. And, it is desirable to use polyester resin Re which is good in touch and excellent in quick-drying property and mold resistance. The single fiber yarn material 3 is a yarn material in which a large number of thin fiber materials are combined. As described above, when polyester resin Re is used as the fiber yarn material 3 ..., there is an advantage that a good quality support band 1 can be realized based on the physical properties of the polyester resin Re.

  Further, as shown in FIGS. 2 and 3, the rubber thread portion 4 is provided with a rubber main portion 4m located on the inner side (center side) and a covering portion 4s located on the outer side and covering the circumferential surface of the rubber main portion 4m. Configure. Polyurethane resin Rp, that is, polyurethane rubber is used as a material of the rubber main portion 4m. Thus, if the rubber main body 4m made of the polyurethane resin Rp is used, the physical properties of the polyurethane resin Rp can contribute to the smooth stretching action and the slow return action of the support band 1, and also it is resistant to ultraviolet rays and washing resistance. Also, there is an advantage that it is possible to obtain a support band 1 that is optimal for outdoor use and repeated use. The rubber body 4m can be formed to have a round cross section with a diameter of about 0.5 mm.

  On the other hand, as shown in FIG. 3, the covering portion 4s is configured by spirally winding a nylon thread material 4sc using a nylon resin Rn around the circumferential surface 4mf of the rubber main portion 4m. In the illustrated example, two nylon yarns 4sc. In addition, one nylon thread material 4sc is a thread material in which a large number of thin fiber materials are combined. As a result, the entire surface 4mf of the rubber main body 4m is covered by the covering 4s. Further, as for the volume ratio of the covering portion 4s and the rubber main portion 4m, it is desirable to select 60 to 90% of the covering portion 4s and 10 to 40% of the rubber main portion 4m. If such a covering portion 4s is provided, the rubber thread main portion 4m can be protected by the covering portion 4s, and therefore the durability of the rubber thread portion 4 and further the support band 1 can be enhanced. There is an advantage that the stability and smoothness of the stretching action can be enhanced by exerting the guide function of

  Then, the elastic stretchable member 2 is sewn using the above-described fiber thread material 3 and the rubber thread portion 4. In this case, as shown in FIG. 2, the fiber yarn materials 3 are sewn as yarns in the width direction Fw and the longitudinal direction Fv, that is, the weft 3w and the warp 3v. At the time of sewing, a plurality of rubber thread portions 4 arranged in the width direction Fw are sewn simultaneously. That is, sewing is performed so as to form a braided knitting structure. The number of rubber thread portions 4 in the width direction Fw is preferably around 20. Therefore, the number of fiber thread materials 3 ... used as warps is also around 20 in the width direction Fw. The fiber yarn materials 3 used as the warp yarns 3v are alternately used as upper yarns or lower yarns in the width direction Fw. The whole sewing method can use a well-known sewing method, and can be implemented without being limited to a specific sewing method.

  As a result, it is possible to obtain the belt-like elastic stretchable member 2, and in the case of the example, it is possible to elastically stretch only in the longitudinal direction Fv. Therefore, as shown in FIG. 4, by applying a tensile force in the longitudinal direction Fv to the longitudinal length Lo in the natural state where no external force is applied, it can be extended to the length Lv, and this length It is desirable to set the height Lv to about twice the length Lo. In addition, as shown in FIG. 5, it is desirable to select the dimension (width Lw) of the width direction Fw of the elastic elastic member 2 in the range of about 20-30 [mm].

  On the other hand, when the elastic stretchable member 2 is manufactured (sewn), four (generally, at least two or more) continuous loop member portions 5a, 5b... Are formed by using the elastic stretchable member 2 Do. It is also possible to manufacture four loop member parts 5a, 5b,... In advance, and then connect the loop member parts 5a, 5b,... Sequentially, but it is preferable to manufacture as follows. .

  First, as shown in FIGS. 5 and 6, one main loop portion 11 is formed by the elastic stretchable member 2. In this case, it is desirable to select the entire circumferential length Lf (≒ Lm × 2) of the main loop portion 11 to be approximately 2400 mm. Further, the main loop portion 11 is provided with three suture fixing portions 12x, 12y and 12z by overlapping opposing surfaces, setting them in a line of two sheets, and sewing together predetermined positions. Thus, as shown in FIG. 6, four loop member portions 5a, 5b, 5c, 5d of the same size can be formed, and the total circumferential length Ls of each loop member portion 5a, 5b. It becomes about 600 [mm]. It is preferable that each suture fixing portion 12x be fixed over a width Lc (for example, about 10 mm) in a certain range in the longitudinal direction Fv in order to increase the fixing strength. In the illustrated example, after the main loop portion 11 is manufactured, the suture fixing portions 12x are provided. However, the main loop portion 11 and the suture fixing portions 12x may be manufactured simultaneously.

  When forming each loop member portion 5a, if such a formation method is used, the easiness of manufacture of the support band 1 can be further enhanced, and in particular, an advantage that sufficient tensile strength in the longitudinal direction Fv can be ensured is there. Thereby, the intended strength training support band 1 shown in FIG. 1 can be obtained. As described above, as the dimensions of the muscle strength training support band 1, as shown in FIGS. 5 and 6, the width Lw in each of the loop members 5a, 5b, ... is selected in the range of 20 to 30 mm. And, it is desirable to select the entire circumferential length Ls (≒ Lp × 2) in the range of 500 to 600 [mm]. This can be implemented as a form having the most desirable dimensions, such as being easy to hold by hand and easy to use.

  Therefore, according to the muscle strength training support band 1 according to the present embodiment, the fiber thread material 3 used in the width direction Fw and the longitudinal direction Fv and the plurality of rubber thread portions 4 arranged in the width direction Fw are arranged. In order to use a belt-like elastic stretchable member 2 which can be elastically stretched at least in the longitudinal direction Fv obtained by sewing, a temporary and excessive load (power) is applied to the user without any adverse effect on the user, and the smooth stretch is performed. be able to. Therefore, even a user who is involved in rehabilitation of an injury that is easily affected by excessive load, preparation work before exercise, or an elderly person can be used safely and safely. Further, by using the band-like elastic stretchable member 2, it is sufficient to form at least two or more continuous loop member portions 5a, 5b..., So that the whole configuration can be simplified. Therefore, while being able to aim at the improvement of manufacturability and mass productivity by reduction of the number of processes at the time of manufacture, it can contribute also to the cost reduction by reduction of a part mark.

  In addition, since the configuration is simple, as described later, the degree of freedom of the usage pattern is increased, and the diversity (multifunctionality) can be further enhanced. Moreover, since the combination of each loop member part 5a, 5b ... becomes possible, the intensity | strength of load can be adjusted easily. That is, in the case of the example, since the four loop member portions 5a, 5b, 5c and 5d are provided, the respective loop member portions 5a can be combined so as to be double, triple and quadruple. This makes it possible to double, triple or quadruple the strength (load) applied to the muscle, and for example, the strength so far is insufficient. Or I want to get muscle as much as possible in a short time. Etc. can be properly met.
