Description

  The present invention relates to a foot cover and a method for manufacturing the foot cover.

  The foot cover is generally configured to be hidden in the shoe when the shoe is worn. Therefore, since the area of the part which covers a leg | foot is small, a foot cover is easy to take off during wear. In this regard, for example, in the foot cover described in Patent Document 1, rubber is provided along the periphery of an opening (wearing mouth) for putting in and out the foot. Thereby, in this foot cover, the adhesiveness with a leg | foot is improved and the drop-off | omission during wear is suppressed.

Utility Model Registration No. 3165733

  The structure of the conventional foot cover is effective from the viewpoint of suppressing the foot cover from dropping off. However, in the conventional foot cover, a step is inevitably caused by the thickness of the rubber provided on the periphery of the opening. For this reason, the conventional foot cover has a problem in that it feels uncomfortable at the portion where the rubber is provided.

  An object of this invention is to provide the manufacturing method of the foot cover and foot cover which can aim at the improvement of wearability, suppressing the drop-off | omission during wear.

  The foot cover according to the present invention is a foot cover that covers from the toe portion of the foot to the buttocks, and is made of a bottom portion and a stretchable fabric, and surrounds the periphery of the bottom portion and is sewn to the bottom portion. And a covering part having a mouth part into which the wearer is put, wherein the covering part has substantially the same thickness other than the stitched part from the periphery to the bottom part of the mouth part.

  In this foot cover, the covering portion has substantially the same thickness except for the stitched portion from the periphery of the wear mouth portion to the bottom portion. Thereby, in a foot cover, since a level | step difference does not arise in a coating | coated part, a discomfort is not felt during wear. Here, in the case where a member having elasticity such as rubber is not provided in the wearing mouth portion, it is difficult to ensure adhesion, and the foot cover may fall off during wearing. On the other hand, in the foot cover of this invention, since the coating | coated part is comprised with the fabric which has a stretching property, adhesiveness with a leg | foot is securable. Therefore, in the foot cover, it is possible to improve the wearability while suppressing the dropout during wearing.

  In one embodiment, the wearing mouth part may become narrow in width from the toe part side toward the heel part side. Thereby, in a foot cover, the adhesiveness with a leg | foot is further securable. Therefore, in the foot cover, it is possible to satisfactorily suppress falling off during wearing.

  In one embodiment, an anti-slip member having a higher coefficient of friction than the bottom surface is provided on the bottom surface of the bottom portion on the toe portion side, and an impact absorbing member is disposed on the toe portion side on the inner side surface of the bottom portion. It may be provided. Thus, in the foot cover, since the anti-slip member and the shock absorbing member are provided on the toe portion side to which a load is applied, it is possible to suppress slipping while wearing the foot cover and to reduce the burden on the foot.

  In one embodiment, an anti-slip member having a higher friction coefficient than that of the inner surface may be provided on the inner surface of the covering portion at a position corresponding to the collar portion. Thereby, in a foot cover, it can suppress that a heel part slips down.

  In one embodiment, an opening may be provided on the toe side. Thereby, in a foot cover, a toe is exposed at the time of wear. Therefore, the foot cover can be worn even when wearing a shoe with a toe exposed.

  In the method of manufacturing a foot cover according to the present invention, a method of manufacturing a foot cover that covers from the toe portion of the foot to the heel portion and includes a bottom portion and a covering portion, the step of preparing the bottom portion, and a fabric having elasticity And a step of preparing a covering portion having a substantially U-shape and substantially the same thickness throughout, and a step of stitching the bottom portion and the covering portion together.

  In this foot cover manufacturing method, a covering portion having substantially the same thickness is used throughout. Thereby, since a level | step difference does not arise in a wear mouth part, it can be set as the foot cover which does not feel discomfort during wearing. Moreover, the coating | coated part is exhibiting substantially U shape. When the covering portion having such a shape is stitched to the bottom portion, the width of the wear mouth portion defined by the covering portion becomes narrower from the toe portion side toward the heel portion side. Thereby, it can be set as the foot cover which can ensure adhesiveness with a leg | foot. Therefore, in the foot cover manufacturing method, it is possible to manufacture a foot cover that can improve wearability while suppressing dropout during wearing.

  According to the present invention, it is possible to improve wearability while suppressing dropout during wearing.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numerals, and redundant description will be omitted.

  FIG. 1 is a perspective view showing a foot cover according to an embodiment. 2A is a plan view of the foot cover shown in FIG. 1 viewed from above, and FIG. 2B is a plan view of the foot cover shown in FIG. 1 viewed from the bottom side. FIG. 3 is a side view of the foot cover shown in FIG. FIG. 4 is a view showing the bottom of the foot cover shown in FIG. 1 before stitching. FIG. 5 is a view showing a covering portion of the foot cover shown in FIG. 1 before stitching.

  A foot cover 1 shown in each figure is a sock covering from a toe portion of a foot to a lower portion of a heel portion. The foot cover 1 includes a bottom portion 3 and a covering portion 5. The bottom part 3 is a part which covers the back side of the foot. The fabric of the bottom 3 is preferably a fabric having air permeability and stretchability, and is, for example, cotton, polyester, polyurethane, or a fabric in which they are mixed. As the fabric of the bottom portion 3, a material having a quick drying property, a material having a deodorizing effect, and a material having a water absorption exothermic property may be used.

  The bottom 3 is provided with an anti-slip member 7 and a cushion member (impact absorbing member) 9. The anti-slip member 7 is disposed on the bottom surface 3 a of the bottom portion 3. The anti-slip member 7 is disposed on the toe side of the bottom 3 and has, for example, a substantially elliptical shape. The anti-slip member 7 is a material having a higher coefficient of friction than the fabric (bottom surface 3a) of the bottom 3, and, for example, a resin or the like is bonded thereto. The thickness and size of the anti-slip member 7 may be set as appropriate.

  The cushion member 9 is disposed on the inner surface 3 b of the bottom portion 3. The cushion member 9 is disposed on the toe side of the bottom 3 and has, for example, a substantially circular shape. The cushion member 9 and the anti-slip member 7 are disposed, for example, at positions overlapping with the bottom portion 3 interposed therebetween. As the cushion member 9, for example, a member having low resilience is preferably used. The cushion member 9 is preferably covered with, for example, a pile fabric from the viewpoint of contact with the sole. The thickness and size of the cushion member 9 may be set as appropriate.

The covering portion 5 is a portion that covers the toe portion, the upper portion, and the heel portion of the foot. The coating | coated part 5 is formed, for example with the cloth | texture which heat-processed to the heat sealing | fusion elastic fiber, and has a stretching property. Specifically, the fabric of the covering portion 5 includes, for example, nylon (Ny) and polyurethane (Pu) yarns, and has a basis weight of 195 g / m ² . This fabric has a structure in which the end face cannot be removed when it is cut.

  The covering portion 5 is stitched to the periphery of the bottom portion 3. As shown in FIG. 5, the covering portion 5 has a substantially U shape before being sutured. Specifically, the covering 5 is shaped like a horseshoe. That is, the covering portion 5 has a shape in which both end portions enter inside when placed flat, and both end portions are close to each other. When such a covering portion 5 is stitched to the bottom portion 3, as shown in FIGS. 1 and 2A, a wear mouth portion 13 into which a foot can be inserted is defined by the covering portion 5. By sewing the covering portion 5 and the bottom portion 3 having the above-described configuration, the width of the wearing mouth portion 13 is narrowed from the toe portion side toward the heel portion side. In addition, the toe part side mentioned here includes the vicinity of the base of the thumb while the foot cover 1 is worn.

  The end face of the covering portion 5 that defines the wear mouth portion 13 is not sewn (uncut). As described above, the fabric of the covering portion 5 has a structure in which the end face cannot be unraveled. Thereby, since it is not necessary to process the end surface, the covering portion 5 has substantially the same thickness from the wear mouth portion 13 to the bottom portion 3 in portions other than the stitched portion S. That is, as shown in FIG. 5, the covering portion 5 is composed of one piece of cloth in the present embodiment, and the thickness is substantially equal throughout. Thereby, in the coating | coated part 5, since it does not have a part which becomes thick, a level | step difference is not provided. In addition, the level | step difference said here says that an unevenness | corrugation is felt when touching cloth.

  As shown in FIG. 2A, the covering portion 5 is curved with a predetermined radius of curvature on the toe portion side. Moreover, as shown in FIG. 5, the both ends of the coating | coated part 5 before stitching | curving have comprised curved shape. Thereby, as shown in FIG. 3, the part corresponding to the collar part of the coating | coated part 5 has comprised the shape curved to the toe part side after a stitch | suture. In this way, by sewing the covering portion 5 whose both end portions are curved, a curved shape is formed so as to wrap the heel portion along the heel portion. Thereby, in the foot cover 1, adhesiveness can be improved.

  An anti-slip member 11 is provided at a portion corresponding to the collar portion of the covering portion 5. Specifically, the anti-slip member 11 is located on the foot opening 13 side. The anti-slip member 11 is disposed on the inner side surface 5 a of the covering portion 5. The anti-slip member 11 is a material having a higher coefficient of friction than the cloth (inner side surface 5a) of the covering portion 5, and, for example, a resin or the like is bonded thereto.

  A method for manufacturing the foot cover 1 having the above configuration will be described. First, the bottom 3 shown in FIG. 4 and the covering 5 shown in FIG. 5 are prepared. The anti-slip member 7 and the cushion member 9 may be provided in the bottom portion 3 in advance, or may be provided after the bottom portion 3 and the covering portion 5 are stitched together. Subsequently, the bottom portion 3 and the covering portion 5 are stitched together. Specifically, for example, after both end portions of the covering portion 5 are stitched, the covering portion 5 is stitched along the periphery of the bottom portion 3. Then, the anti-slip member 11 is provided on the covering portion 5. The foot cover 1 is manufactured as described above.

  As described above, in the foot cover 1 according to the present embodiment, the covering portion 5 has substantially the same thickness except for the stitched portion S from the periphery of the wear mouth portion 13 to the bottom portion 3. Thereby, in the foot cover 1, since the level | step difference is not provided in the coating | coated part 5, a discomfort is not felt during wear. Here, in the case where a member having elasticity such as rubber is not provided in the wearing mouth portion 13, it is difficult to ensure adhesion, and the foot cover may fall off during wearing.

  Moreover, as shown in FIG. 6, the conventional coating | coated part 20 is exhibiting substantially V shape in the state before stitching | suture with a bottom part. When such a covering portion 20 is stitched to the bottom portion, the wear mouth portion defined by the covering portion 20 becomes wide, and it is difficult to ensure adhesion. Therefore, in the conventional foot cover, in order to suppress omission during wearing, it was necessary to provide a member having elasticity such as rubber at the periphery of the wearing mouth portion.

  On the other hand, in the foot cover 1 of this embodiment, the coating | coated part 5 which exhibits a substantially U shape in the state before stitching | suture is used. By stitching the covering portion 5 with the bottom portion 3, the width of the wearing mouth portion 13 becomes narrower from the toe portion side toward the heel portion side. Thereby, in the foot cover 1, adhesiveness with a leg | foot is securable. Therefore, the foot cover 1 can suppress dropping during wearing. As described above, in the foot cover 1, it is possible to improve wearability while suppressing dropout during wearing.

  In the present embodiment, a non-slip member 7 having a higher coefficient of friction than the bottom surface 3 a is provided on the bottom surface 3 a of the bottom portion 3, and a cushion member 9 is provided on the inner side surface 3 b of the bottom portion 3. Thereby, in the foot cover 1, it is possible to suppress slipping while wearing the foot cover 1 by the anti-slip member 7, and it is possible to reduce the burden on the foot by the cushion member 9.

  In this embodiment, the non-slip member 11 having a higher coefficient of friction than the inner side surface 5a is provided on the inner side surface 5a of the covering portion 5 at a position corresponding to the collar portion. Thereby, in the foot cover 1, it can suppress that a collar part slips down.

  In the present embodiment, since the wear mouth portion 13 is not processed at the periphery, the number of manufacturing steps can be reduced and the cost can be reduced as compared with the case where a member such as rubber is provided at the periphery.

  The present invention is not limited to the above embodiment. FIG. 7 is a perspective view showing a foot cover according to another embodiment. As shown in FIG. 7, the foot cover 1 </ b> A has an opening 15 at the tip. Thereby, in 1 A of foot covers, a toe is exposed at the time of wear. Therefore, the foot cover 1 </ b> A can be worn even when wearing shoes with toes exposed.

  In the said embodiment, although the raw material of the bottom part 3 and the coating | coated part 5 is made into a different material, the same material may be sufficient as the bottom part 3 and the coating | coated part 5. FIG.

  In the said embodiment, although the thing which heat-processed to the heat sealing | fusion elastic fiber was mentioned as an example as material | dough of the coating | coated part 5, the material | dough of the coating | coated part 5 is not limited to this. The fabric of the covering portion 5 may be a fabric that has stretchability and whose end cannot be removed when it is cut.

  Hereinafter, the present embodiment will be described in more detail by way of examples, but the scope of the present embodiment is not limited by the contents described below.

  About the Example which has the said structure, and Comparative Examples 1 and 2, the stretching force, thickness, and pressure were measured. The comparative example 1 used the thing by which the string-like member which has a stretching property was provided in the wear mouth part, and the comparative example 2 used the thing by which flat rubber | gum was provided in the wear mouth part.

[Elasticity]
The stretching force of the foot cover was measured using a precision universal testing machine (Autograph AGS-H: manufactured by Shimadzu Corporation). The stretching force was determined by measuring the value of the load when the sample of 50 mm was sandwiched between the chucks and stretched to 100% elongation (50 mm) and the load when returning to the original size after stretching. Each sample was measured three times, and the average value was calculated. The measurement results are shown in Table 1. In Table 1, the stretching force is indicated by [kgf]. Further, in Table 1, the return rate is obtained by (size of sample when 100% stretched−size when loosened) / (original size).

[Thickness]
The thickness of the foot cover was measured using a shopper type thickness measuring instrument (No. 129-A: manufactured by Yasuda Seiki Seisakusho). The thickness was measured at the periphery of the wear mouth portion (wear mouth portion) and the other portion (flat portion) in the covering portion. The measurement results are shown in Table 2. In Table 2, the thickness is shown in [mm].

  As shown in Table 2, in the examples, there is no difference in thickness between the mouth portion and the flat portion. Therefore, in the embodiment, no step is generated in the covering portion. In Comparative Examples 1 and 2, there is a difference between the mouth portion and the flat portion, and there is a step.

[Pressure]
The pressure applied to the foot cover was measured using an air pack pressure measuring device (A0101-G: manufactured by AIM Techno Co., Ltd.). Wearing pressure is measured using the average foot shape of an HQL Japanese 20s female, and an air pack pressure measuring device is placed at the base of the foot and the base of the thumb, and the value is measured 1 minute after the foot cover is worn. did. Each sample was measured three times and the average value was calculated. Table 3 shows the measurement results. In Table 3, the pressure is indicated by [hPa].

  As shown in Table 3, in the examples, there was no difference in the pressure between the wear mouth portion and the flat portion on the toe side.
