Description

  The present invention relates to a foot cover that is hidden inside a shoe (preferably a shoe covering the instep) when worn, and in particular, the width of the foot and the height of the instep vary depending on individual differences. However, the present invention relates to a foot cover that enhances fit, is easy to wear, is comfortable to wear, and is less likely to be removed or displaced due to an action such as walking.

Wearing shoes such as pumps on bare feet has become established as a fashion. In this case, if the pump and the sole are in direct contact with each other, the sweat inside the shoe may become stuffy due to sweat generated on the foot, resulting in an uncomfortable feeling.
Therefore, we propose a thin foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and the mouth is greatly cut so that it is not exposed from the pump when worn. Has been. If you wear this foot cover and wear pumps, it looks like you are wearing pumps on your bare feet, and the foot cover is between the sole and the pumps, so sweat sweats the inside of the shoes Can be prevented.

In addition, although such a foot mounting device is described as a foot cover in this specification, it may be described as a socks cover, inner socks, nude socks, cover socks, or the like.
Since such a foot cover has a large cut mouth so as not to be exposed from the pump, the wearing position may be shifted or removed due to friction during walking. On the other hand, if the mouth is made small, it will be exposed from the pumps. A foot cover developed in view of such a problem is disclosed in the following prior art documents.

In Japanese Patent Laid-Open No. 10-292206 (Patent Document 1), the foot cover may be removed from the bare foot due to friction between the pump and the foot cover during walking, or the foot cover may be removed when the pump is removed. In order to prevent shifting, a foot cover in which a friction imparting body is attached to the inner surface of the heel contact portion is disclosed.
Japanese Utility Model Registration No. 3165733 (Patent Document 2) discloses that when a rubber string is provided along the periphery of the opening of the foot cover disclosed in Patent Document 1, the rubber string bites into the foot, so that the rubber is applied to the foot. In consideration of problems such as laces being attached, feeling pain, and poor comfort, a belt-like stretch that has flat rubber along the periphery of the opening so that one side touches the foot The foot cover which formed the part is disclosed.

JP-A-10-292206 Utility Model Registration No. 3165733

  Here, the foot cover friction imparting body disclosed in Patent Document 1 may not be sufficient. In this case, the foot cover may be removed or the wearing position may be shifted when walking or taking off shoes. I'll be relaxed. In the flat rubber disclosed in Patent Document 2, since the flat rubber is provided over the entire periphery of the opening (depending on the elasticity of the flat rubber), the opening is sufficient when the foot cover is worn. In addition to the fact that it is difficult to wear without opening, there is also a problem that the foot cover may be removed or the wearing position may be shifted when the shoes are taken off as in the case of the foot cover disclosed in Patent Document 1.

In order to increase the support force against such a problem, a fabric having a high support force may be provided in the vicinity of the position of the arch. In other words, an elastic fabric that does not stretch easily is provided on the sole contact surface at the sole, and the foot cover is removed or the wearing position is shifted when walking or taking off shoes by properly tightening around the foot. It has been carried out to suppress the loosening (improving the fit). In addition, when the stretchable fabric that does not easily stretch is provided on the sole contact surface in the sole, the form stability that stabilizes the form of the foot cover is also improved.

However, since it is natural that the width of the foot and the height of the instep differ depending on the individual, it is possible to accommodate everyone by providing a stretch fabric that is not easily stretched on the sole contact surface at the sole. Therefore, there is a possibility that the fit cannot be improved sufficiently.
The present invention was developed in view of the above-mentioned problems of the prior art, and the purpose of the present invention is naturally that the width of the foot and the height of the instep vary depending on individual differences. It is an object to provide a foot cover that enhances fit, is easy to wear, is comfortable to wear, and is less likely to be removed or displaced due to an action such as walking.

In order to achieve the above object, the foot cover according to the present invention employs the following technical means.
That is, the foot cover according to the present invention is a foot cover that covers the instep, the heel, and the sole, and includes an instep portion, a heel portion, and a sole portion that are formed of a stretchable fabric. In contrast, an opening for inserting and removing the foot on the opposite side of the upper and lower sides is provided, and the sole contact surface of the sole is a stretchable fabric that is less likely to stretch than the stretchable fabric of the instep portion, and has a plurality of holes It is characterized in that an elastic fabric having an open part is provided.

  According to the foot cover of the present invention, it is natural that the width of the foot and the height of the instep vary depending on individual differences, but even so, the fit is improved, it is easy to wear and comfortable to wear, and walking, etc. It is possible to reduce the possibility of detachment or displacement due to movement.

BRIEF DESCRIPTION OF THE DRAWINGS It is the whole perspective view of the foot cover which concerns on embodiment of this invention, Comprising: (A) Outer side (front side, the opposite side to a skin contact surface), (B) Inside (back side, skin contact surface) which turned over cloth Side). 2A is a top view of the foot cover of FIG. 1, FIG. 3B is a top view of only the sole, and FIG. 3C is a top view illustrating another example of the stretchable fabric having a plurality of holes.

FIG. 1 is an overall perspective view showing a wearing state in which a foot cover 100 according to the present embodiment is worn on a foot F, and FIG. 1 (A) is the outside thereof (front side, opposite to the skin contact surface). FIG. 1B is an overall perspective view showing a state in which the foot cover 100 shown in FIG. 1A is turned upside down (inside the fabric turned over (back side, skin contact surface side)). FIG. 2 (A) is a top view of the foot cover 100 shown in FIG. 1, FIG. 2 (B) is a top view of only the sole, and FIG. 2 (C) is formed with a plurality of holes. It is a top view which shows the other example of the stretchable fabric. Here, FIG. 1 and FIG. 2 assume a state in which the foot cover 100 is worn on the wearer's foot F. That is, the foot cover 100 according to the present embodiment is not limited, but is formed of a thin stretch knitted fabric used for pantyhose or the like, and thus is not illustrated assuming such a case. Since it is in a contracted state and it is difficult to understand the shape, it is assumed as described above. In particular, in FIG. 2A, in order to easily understand the features of the foot cover 100, the sole 130 is drawn so that it can be seen better than the actual wearing state.

  Note that there are various foot cover structures, and the present invention is not limited to a specific structure. The features described later (the sole contact surface of the sole portion is more elastic than the elastic fabric of the sole portion). The foot cover 100 is composed of any stretchable fabric that is difficult to stretch and is provided with a stretchable fabric having a plurality of holes. Basically, it does not matter what kind of fabric is used, the pattern of the fabric, and the joining method of the fabric. Therefore, the structure of the foot cover 100 shown below is merely an example.

Further, the fabric forming the foot cover 100 is not limited, but a bare heaven (bare tent: a yarn (cotton, wool, etc.) wound with a yarn (cotton, wool, etc.) around a polyurethane yarn as a shaft (
Flat knitted fabric knitted using covered yarn), tricot (warp knitted fabric knitted with a tricot machine, which is a type of warp knitting machine), pantyhose fabric (knitting including polyurethane yarn and nylon yarn) Etc.) are preferably used. Among these, in particular, Bear Sky is (1) excellent in elasticity, (2) good shape stability and little shape change after washing, and (3) soft texture and good fit. (4) Wrinkles and creases are difficult to be formed, (5) The porous structure is breathable, and (6) When cotton is included, it is preferable for the foot cover in terms of touch and hygroscopicity.

  Furthermore, the foot cover 100 according to the present embodiment is a foot cover that covers the instep, the heel, and the sole of the wearer's foot F, and the instep portion 110 and the heel portion 120 formed of stretchable fabric. And a sole part 130, an opening 150 is provided for putting the foot in and out on the opposite side of the sole part 130, and the sole contact surface of the sole part 130 extends more than the elastic fabric of the sole part 130. A stretchable fabric 140 that is difficult to stretch and has a plurality of holes 142 is provided. As described above, the fabric of the foot cover 100 is (but is not limited to) the instep portion 110, the heel portion 120, and the sole portion 130 knitted including a thin stretchable fabric used for pantyhose or the like. And formed. The stretchable fabric 140 is preferably provided on the sole contact surface of the sole portion 130 and in the vicinity of the position of the arch.

The stretchability of the stretchable fabric 140 is less stretchable than the stretchable fabric of the sole 130, but in addition to this, the stretchable fabric of the instep 110 and / or the stretchability of the heel 120. It may be harder to stretch than the fabric.
Moreover, although not limited, the foot cover 100 shown below is common to the left and right, and is preferable in that it does not mistake to wear the left and right because it is common to the left and right. When the foot cover 100 is not shared between the left and right sides, the left foot and the right foot have a symmetrical shape.

More specifically, the foot cover 100 will be described.
The instep 110 forming the foot cover 100 includes an instep covering 110A that covers the instep, a toe covering 110B that covers the toes, and a foot covering 110C that covers the sides of the toes. It should be noted that the instep covering portion 110A, the toe covering portion 110B, and the foot side covering portion 110C in the instep portion 110 are not composed of one piece of fabric, and the instep portion 110 is composed of two or more fabrics. It doesn't matter.

The foot cover part 110, the heel part 120, and the sole part 130 are stitched together at respective boundaries by a sewing line S, so that the foot cover 100 is formed three-dimensionally.
On the upper edge of the instep part 110 and the upper edge of the heel part 120 forming the opening 150, the instep side elastic thin cloth 112 and the heel side elastic thin cloth 122 are provided around the opening 150. Is provided. Note that only the instep side stretchable narrow fabric 112 may be provided, and as the instep side stretchable narrow fabric 112 and the heel side stretchable narrow fabric 122, another type of stretchable narrow fabric may be provided. You may make it provide.

  Further, on the upper edge of the heel portion 120 of the foot cover 100 and on the inner side of the foot cover 100 (side where the foot F contacts: the skin side), the heel portion is made of a thin transparent sheet such as silicon resin. It is also preferable to provide 124. Thereby, the adhesiveness with the heel of the foot F can be improved, and the foot cover 100 can be further prevented from being displaced from the heel portion of the foot F. Note that this buttocks slip stopper 124 is not an essential component in the foot cover according to the present invention.

  Further, in the sole portion 130, the sole portion made of a thin sheet of silicon resin or the like is provided on the side opposite to the side with which the foot F is in contact (the side in contact with the inner bottom of the pump when the pump is worn). Is also preferable. Thereby, the adhesiveness with the inner bottom of a pump can be improved, and it can prevent that the position of the foot cover 100 in a pump shifts | deviates. In addition, this sole non-slip | skid is also not an essential structure in the foot cover which concerns on this invention.

  In the foot cover 100, an elastic fabric that forms the foot portion 110, an elastic fabric that forms the heel portion 120, and an elastic fabric that forms the sole portion 130. The same co-fabric may be used. That is, except for the stretchable fabric 140 and the suture thread, the foot cover 100 may be formed of the same type of stretchable fabric (stretchable fabric used for pantyhose etc.).

  Further, in the foot cover 100, an elastic fabric that forms the instep portion 110, an elastic fabric that forms the heel portion 120, and an elastic fabric that forms the sole portion 130, which form the foot cover 100, All three may be made of different types of stretch fabrics instead of the same type of stretch fabrics, any two of which are made of the same type of stretch fabrics and the other one is a different type of stretch fabric It may be formed of dough. In this case, the stretchable fabric 140 may be the same as any stretchable fabric or may be different from any stretchable fabric.

What is characteristic is an elastic fabric that is less likely to stretch than the elastic fabric of the sole portion 130 in the vicinity of the arch of the sole contact surface in the sole portion 130, and a plurality of hole portions 142 are opened. The point is that a stretchable fabric 140 is provided. The stretchable fabric 140 includes a plurality of (here, 14) hole portions 142 having a predetermined diameter as shown in FIG.
The stretchable fabric 140 may be a stretchable fabric 240 as shown in FIG. The stretchable fabric 240 shown in FIG. 2C includes a plurality (9 in this case) of hole portions 242 having a diameter larger than the diameter of the hole portion 142 of the stretchable fabric 140 shown in FIG. .

  As described above, the elastic fabric provided in the vicinity of the arch of the sole contact surface in the sole portion 130, which is less stretchable than the elastic fabric of the sole portion 130, has a predetermined number of predetermined diameters. A hole of a circular shape (not limited to a circular shape, and need not be stretchable due to the absence of fabric) is provided. The degree of tightening around the foot can be set appropriately by changing at least one of the shape (here circular), size (here diameter), number and arrangement of these holes, It is possible to improve the fit by suppressing the foot cover 100 from being removed or the wearing position being shifted when the shoes are taken off.

  Furthermore, as shown in FIG. 2 (B) or FIG. 2 (C), by providing a plurality of holes at symmetrical positions, the tightening force appropriately adjusted by the presence of the holes can be increased in the front-rear direction of the foot and In order to act equally in the left-right direction, the tightening force acts over 360 °, so that the elasticity of the sole portion 130 of the foot cover 100 does not have directionality (or does not generate significant directionality). It is preferable in that it can be performed.

  In particular, even when the foot width is wide or the instep is high, it is preferable in that it can be comfortably worn with improved fit. The strength of the tightening force can be adjusted by the ratio of the total opening area of the hole to the entire area of the stretchable fabric, and the directionality of the tightening force can be controlled by the shape and / or arrangement of the hole. As an example of product development, in addition to the size, at least one of the shape, size, number and arrangement of the holes in the stretchable fabric 140 (or stretchable fabric 240) is changed to be used for a wide leg or a high leg It is conceivable to provide the user with a foot cover for the former.

  The stretchable fabric 140 and the stretchable fabric 240 may be provided on the sole portion 130 by joining with an adhesive or an adhesive tape, or may be provided on the sole portion 130 by joining by sewing. As described above, the joining of the stretchable fabric 140 and the stretchable fabric 240 is not limited. However, when the joining is not performed by sewing, an adhesive tape in which an adhesive is applied to one or both sides of the belt-like member is used. In addition, it is preferable that the adhesive material is melted by heating, and the stretchable fabric 140, the stretchable fabric 240, and the stretchable fabric of the sole portion 130 are bonded by heat bonding except for the hole portion. In addition, this joining includes those by thermocompression bonding, those by thermal welding, those by thermal fusion, and the like.

  As described above, the foot cover 100 is an elastic fabric that is less stretchable than the elastic fabric of the sole portion 130 in the vicinity of the arch of the sole contact surface of the sole portion 130, and has a plurality of hole portions 142. A stretchable fabric 140 was provided. Since the stretchable fabric 140 having the plurality of holes 142 is provided with a predetermined number of circular holes having a predetermined diameter (the diameter and / or the number of the holes may be changed). It is natural that the degree of tightening around the foot can be set appropriately, and it is natural that the width of the foot and the height of the instep vary depending on individual differences. It is easy and comfortable to wear, and can be less likely to be removed or displaced due to walking or the like.

As described above, according to the foot cover 100 according to the present embodiment, it is natural that the width of the foot and the height of the instep differ depending on individual differences. It is easy and comfortable to wear, and can be less likely to be removed or displaced due to walking or the like.
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention is suitable for a foot cover to be worn with bare feet, and it is natural that the width of the foot and the height of the instep vary depending on individual differences, but even so, it improves the fit and makes it easy to wear and comfortable to wear. It is particularly preferable in that it can be less likely to be removed or displaced due to walking or the like.
