  Hereinafter, embodiments of an insole for shoes according to the present invention will be described with reference to the accompanying drawings. The insole of the present invention is an insole for footwear used by being inserted into footwear such as shoes, for example. 1 to 6 show a first embodiment of a shoe insole according to the present invention. As shown in FIGS. 1, 2, and 3, a shoe insole 10 includes an insole main body 14 in which a tatami mat sheet 12 is stacked in multiple layers, and a stitching portion 16 that sews the insole main body 14.

  As shown in FIGS. 1, 2, and 4, the insole body 14 is an insole body formed in a shoe shape in a plan view, that is, a substantially foot shape. The insole main body 14 is provided with a tatami mat sheet 12 formed by weaving grass, which is a top material, superimposed on a plurality of layers. The insole main body 14 is folded so that one tatami mat sheet 12 has a required width L and circulates in the same direction, and is superimposed on a plurality of layers to form a superimposed body. In the present embodiment, the insole body 14 realizes a stacked structure in which the sheet portions 18a to 18e serving as the respective layer portions are stacked and overlapped by folding and overlapping one tatami mat sheet body. The insole body 14 is formed in four layers by laminating a plurality of substantially identical sheet portions 18a to 18d formed in a shoe sole shape, and each sheet portion 18a to 18d has a front end portion on the toe side. 22 or the rear end 24 on the heel side is connected by the folded end 20. Further, the portion corresponding to the heel portion on the heel side of the arch portion of the insole main body 14 is further overlapped with the seat portion 18e of only the heel portion which is a part of the foot shape. Therefore, in the present embodiment, the insole body 14 includes four layers of shoe-shaped sheet portions 18a to 18d, and a heel-shaped sheet portion 18e is further overlapped only on the heel portion. Has a laminated structure with 4 layers, 5 layers on the heel side of the arch. Thereby, the front end part 22 and the rear end part 24 of the insole main body 14 of the shoe sole shape are exposed to the outside as the folded-back end part 20, and have a structure without an overlapping layer.

  The insole body 14 has a width before the first turn of the tatami mat sheet 12 (see symbol L in FIG. 5) set to a length substantially equal to the length of the required shoe, that is, the length from the toe side to the heel side. In addition, the tatami surface sheet 12 is folded in a winding shape so that the sheet portion to be folded first is wound inside while being folded at the end portions on the toe side and the heel side to form a multi-layer superposed body. Yes. As shown in FIG. 5, in a state in which the tatami mat sheet 12 superimposed on a plurality of layers of the insole body 14 is unfolded, the sheet portions 18 a to 18 d of each layer are folded-back ends of shoe-shaped toe ends or heel ends. The seat portion 18e is integrally connected at the folded back end portion 20 folded at the rear end portion 24 of the insole body 14 of the shoe sole. It is connected. The developed view of FIG. 5 is a schematic diagram, and when actually manufactured, the length and shape of each of the sheet portions 18a to 18e and the folded end portion 20 are set to the thickness of the inner sheet portion to be folded. It is good also as changing according to it and setting a bending pitch suitably.

  The stitching portion 16 sews the outer inner edge portion of the insole body 14 formed by folding the tatami surface sheet 12 into a winding shape as described above, and fixes the insole body 14 integrally, that is, by laminating the laminated sheet portions. This is a fixing means. The stitching portion 16 may stitch all or part of the outer edge of the insole body 14. In the present embodiment, the stitching portion 16 is formed by sewing the outer edge of the insole body 14 excluding the front end portion 22 and the rear end portion 24 of the shoe sole shape that is the folded end portion of the molded insole body 14 with a sewing machine or the like. Sewn. A zigzag straight line appearing on the side surface of the insole main body 14 in FIGS. 1 and 2 indicates a sewing thread that wraps around the outer edge of the tatami mat sheet (sheet portions 18a to 18e) superimposed on a plurality of layers by over stitching. In addition, it is good also as sewing the whole periphery by sewing the front-end part 22 and the rear-end part 24 used as a folding | turning edge part. Furthermore, the rearmost end portion 26 (of the sheet portion 18e) of the tatami mat sheet 12 that is folded back so as to circulate in the same direction as described above is a tatami mat sheet (sheet portion) that is laminated on the uppermost layer at the arch portion of the insole body 14. 18d), it is joined to the tatami surface sheet 12 on which the rearmost end portion 26 is laminated by zigzag stitching or the like by the second stitching portion 28.

  When manufacturing the insole 10 of the shoe according to the present embodiment, for example, as shown in FIG. 6A, a normal tatami mat sheet BS is formed by weaving a normal tatami mat using a weed loom. . According to the length (L) in the longitudinal direction of the required shoe, for example, the rectangular original tatami mat sheet BS is folded back so as to circulate in the same direction while valley-folding along the dotted line in the figure, and a plurality of layers (Four layers in the example of FIG. 6), and the end portion is also partially overlapped, and as shown in FIG. 6 (b), the length of the original tatami mat sheet BS after folding is finally Is set to be approximately the same as the longitudinal length of the sole of the required shoe size. For example, when manufacturing an insole for a shoe having a size of 26 cm, the initial folding width L is set to about 26 cm (or slightly smaller) so that the whole overlaps with the first folding width. It is set so that the front-rear length after folding is about 26 cm. In FIG. 6, the four folding pitches have the same width, but the folding pitch may be appropriately set in consideration of the overlapping thickness and the like. When folding back the original tatami mat sheet BS, pressurize the folded part with water vapor and soften it, and then dry it, so that the grass that you want to fold into the tatami mat sheet does not break. Can be bent reliably. Next, as shown in FIG.6 (c), it cut | disconnects according to shoe sole shape from the folded original tatami surface sheet | seat BS by cutting means, such as a cutter, and as shown in FIG.6 (d), tatami surface sheet | seat 12 is obtained. The insole of the insole main body 14 and the rear end 26 of the tatami mat sheet are respectively sewn with a sewing machine or the like, and integrated with the sewn part 16 and the second sewn part 28, so that the insole of the shoe as shown in FIG. 10 is completed. The insole main body 14 has a tatami mat sheet so as not to impede the air permeability from the end edges of the tatami mat sheet laminated in a plurality of layers and the moisture-proof function in the shoe when the insole is inserted into the shoe. It is preferable to sew with the stitching portion 16 in a state in which the edge portion is not blocked. Moreover, the number of layers of each sheet | seat part superimposed may be arbitrary, for example, you may form in 2 layers, 3 layers, 5 layers or more.

  When the insole 10 of the shoe of the present embodiment is inserted into the shoe and used, the tatami surface sheet, which is a natural material, is superimposed on a plurality of layers, so that deodorizing action, insect proofing action, moisture proofing action, etc. by weeds are expected. it can. In addition to being able to reduce cold from the soles and cushioning, it is expected to reduce physical stress and fatigue when standing, walking, and exercising in restaurants, stores, factories, etc. it can. In addition, since the material is a tatami mat, the environmental load at the time of disposal is small. In particular, the insole 10 of the shoe of the present embodiment is folded in a winding shape so as to circulate one tatami mat sheet 12 in the same direction, and is folded back to the front end portion 22 and the rear end portion 24 of the insole main body 14 of the shoe sole shape. Since the portion 20 is formed, it is more durable than a structure in which a plurality of sheets are simply laminated, can be used for a long time, and can provide a practical insole. . In addition, the insole body 14 may be used as the upper surface, that is, the side that contacts the foot, or the lower end, that is, the side that contacts the insole of the shoe.

  The insole of the present invention described above is not limited to the configuration of the above-described embodiment alone, and arbitrary modifications are made without departing from the essence of the present invention described in the claims of the utility model registration. May be.

  The insole of the present invention can be suitably used for various other footwear such as leather shoes, sports shoes, safety shoes, work shoes, boots, boots and the like.
