Description

The present invention relates to a foot cover that hides behind shoes such as pumps (mainly women's shoes with a wide open instep) when worn, and in particular, the foot cover can be removed or positioned even when walking or other movements. Regarding the foot cover that does not easily shift.

Wearing shoes such as pumps on bare feet has become a well-established fashion. In this case, if the pumps and the sole of the foot are in direct contact with each other, the sweat generated on the foot causes the inside of the shoe to get stuffy, which causes discomfort.
Therefore, we propose a foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and a thin foot cover with a large cut so that it will not be exposed from the pumps when worn. Has been done. If you wear this foot cover and wear pumps, it looks like you are wearing pumps on your bare feet, and because the foot cover is between the sole and the pumps, sweat makes the inside of your shoes stuffy. It is possible to prevent it from being lost.

In addition, although such a foot attachment is described as a foot cover in this specification, it may be described as a sock cover, an inner sock, a nude sock, a cover sock, or the like.
Since such a foot cover has a large cut so that it is not exposed from the pumps, the wearing position may shift or come off due to friction during walking or the like. On the other hand, if you make the opening small, it will be exposed from the pumps. A foot cover developed in view of such problems is disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 10-292206 (Patent Document 1) states that the foot cover may come off from bare feet due to friction between the pumps and the foot cover during walking, or the foot cover may come off when the pumps are taken off or put on. In order to prevent the foot from being displaced, a foot cover having a friction-imparting body attached to the inner surface of the heel contact portion is disclosed.
In Japanese Patent Application Laid-Open No. 3165733 (Patent Document 2), if a rubber cord is provided along the peripheral edge of the opening of the foot cover disclosed in Patent Document 1, the rubber cord bites into the foot, so that the rubber is attached to the foot. In view of the problems that the string is attached, pain is felt, and it is not comfortable to wear, a flat rubber is provided along the periphery of the opening so that one side is in contact with the foot. The foot cover forming the portion is disclosed.

Japanese Unexamined Patent Publication No. 10-292206 Utility Model Registration No. 3165733 Gazette

However, the friction-imparting body of the foot cover disclosed in Patent Document 1 may not be sufficient. In this case, the foot cover may come off or the wearing position may shift when walking or taking off and putting on the pumps. do. In the flat rubber disclosed in Patent Document 2, since the flat rubber is provided over the entire peripheral edge of the opening (depending on the elasticity of the flat rubber), the opening is sufficiently provided when the foot cover is worn. In addition to the fact that it may be difficult to put on the foot cover without opening it, there is also a problem that the foot cover is taken off or the wearing position is displaced when the pumps are taken off and put on, as in the case of the foot cover disclosed in Patent Document 1.

The present invention has been developed in view of the above-mentioned problems of the prior art, and an object thereof is that the opening is sufficiently opened when the foot cover is worn so that the foot cover is easy to wear, and when walking and pumps. It is an object of the present invention to provide a foot cover in which the foot cover does not come off or the wearing position is not displaced when the foot cover is taken off and put on.

In order to achieve the above object, the foot cover according to the present invention takes the following technical measures.
That is, the foot cover according to an aspect of the present invention covers the toes and the sole including the heel, and exposes the instep and ankle. The foot cover is formed of a sole portion, a side side portion, a heel portion, and a tubular toe portion that covers the toe portion. This foot cover is provided with an opening for putting the foot in and out on the opposite side to the sole of the foot, and an elastic narrow cloth is provided on the upper edge of the side portion forming the opening, and when worn. It is characterized in that, in a lateral view, the angle formed by the longitudinal direction of the stretchable narrow cloth and the upper trailing edge of the toe portion is substantially a right angle.

Preferably, the stretchable narrow cloth is provided on the upper trailing edge of the toe portion forming the opening, and the stretchable narrow cloth provided on the upper edge of the side side portion is viewed laterally when worn. The angle formed by the longitudinal direction and the stretchable narrow cloth provided on the trailing edge of the toe portion can be formed at a substantially right angle.
More preferably, the stretchable narrow fabric can be formed of the same fabric as any of the fabrics forming the toes, soles, sides and heels.

More preferably, the stretchable narrow fabric can be formed of a fabric different from any of the fabrics forming the toes, soles, sides and heels.
Further, the foot cover according to another aspect of the present invention covers the toes. The foot cover is formed of a tubular toe portion that covers the toe portion and a loop-shaped elastic member that is joined to the left and right sides of the toe portion and is locked to the heel when worn. The foot cover is characterized in that the angle formed by the longitudinal direction of the elastic member and the upper trailing edge of the toe portion is substantially a right angle in the lateral view when worn.

More preferably, the stretchable member can be configured to be strip-shaped or string-shaped.

According to the foot cover of the present invention, the opening is sufficiently open when the foot cover is put on, and the foot cover is easily put on, and the foot cover is taken off or the wearing position is displaced when walking or taking off and putting on the pumps. You can prevent it from happening.

Hereinafter, the foot cover according to the embodiment of the present invention will be described in detail with reference to the drawings. It should be noted that there are various structures of the foot cover, and the present invention is not limited to a specific structure, and any structure of the foot cover may be used as long as it has the features described later. It does not matter what kind of fabric constitutes the foot cover, the pattern of the fabric and its sewing. Therefore, the structure of the foot cover shown below is merely an example. The fabric that forms any of the foot covers is an elastic fabric.

<First Embodiment>
1 and 2 show the foot cover 100 according to the first embodiment of the present invention, and FIGS. 3 and 4 show another foot cover 200 according to the first embodiment of the present invention in FIGS. 5 and 4. 6 shows yet another foot cover 300 according to the first embodiment of the present invention. 1, FIG. 3 and FIG. 5 are overall perspective views of the foot cover, and FIGS. 2, 4 and 6 are perspective views in which the foot cover is turned upside down, and any of FIGS. 1 to 6 is shown. It is assumed that the foot cover is worn on the wearer's foot F. That is, since the foot cover according to the embodiment of the present invention is made of elastic fabric such as pantyhose, it will be in a shrunk state if it is not shown in this way, and the shape should be understood. Is difficult, so it is assumed as described above.

Each of the foot covers 100, 200, and 300 is a foot cover that covers the toes of the wearer's foot F and the sole including the heel, and exposes the instep and ankle. Each of the foot covers 100, 200, and 300 is made of a thin elastic fabric (fabric such as pantyhose) in which the opening, which is the opening of the foot cover, is largely cut so as not to be exposed from the pumps when worn.

The foot covers 100, 200, and 300 are formed of toe portions 102, 202, 302, sole portions 104, 204, 304, side side portions 106, 206, 306, and heel portions 108, 208, 308, respectively. An opening is provided on the opposite side of the soles 104, 204, and 304 for putting the foot in and out. Elastic narrow fabrics 116, 216, and 316 are provided on the upper edges of the side portions 106, 206, and 306 forming this opening, respectively.

Further, as shown in FIG. 7, in the heel portions 108, 208, 308, the heel portion slip formed of a thin sheet such as silicon resin on the foot F side (inside) of the elastic narrow fabrics 116, 216, 316. Stops 118, 218, and 318 are provided. As a result, the adhesion of the foot F to the heel can be improved and the foot covers 100, 200, and 300 can be prevented from being displaced from the foot F.
Further, as shown in FIG. 8, in the soles 104, 204, and 304, a thin sheet such as silicon resin is used on the side opposite to the side where the foot F contacts (the side which contacts the inner sole of the pump when the pump is worn). The sole is provided with non-slip 114, 214, 314. This makes it possible to improve the adhesion to the inner bottom of the pump and prevent the positions of the foot covers 100, 200, and 300 in the pump from shifting. The soles of the soles 114, 214, and 314 form a floral pattern.

Further, the differences between the foot cover 100 and the foot cover 200 are as follows.
In the foot cover 100, the toe portion 102, the sole portion 104, the side side portion 106, and the heel portion 108 forming the foot cover 100 are formed of the same fabric, and the elastic narrow fabric 116 is the same as this fabric. It is a common fabric. That is, the foot covers 100 are all made of the same elastic fabric.

On the other hand, in the foot cover 200, the toe portion 202, the sole portion 204, the side side portion 206 and the heel portion 208 are not all the same fabric, and the elastic narrow fabric 216 is different from any of these fabrics. Or the same as any of these fabrics. In this foot cover 200, the toe portion 202, the side side portion 206 and the heel portion 208 of the foot cover 200 are the same lace-shaped or mesh-shaped elastic fabric, and the sole portion 204 and the elastic narrow fabric 216 are the same. Although it is an elastic fabric, it is neither lace-like nor mesh-like, and the sole 204 and the elastic narrow fabric 216 are not the same fabric (may be the same fabric). That is, the foot cover 200 is formed of two or more different types of elastic fabrics, and the elastic narrow fabric 216 is the same as the fabrics of the toe portion 202, the sole portion 204, the side side portion 206, and the heel portion 208. It may be a dough or a different dough.

Unlike the other foot covers 100 and 200, the foot cover 300 is provided with the elastic narrow cloth 312 on the upper trailing edge of the toe portion 302 forming the opening, as shown in FIGS. 5 and 6. ing. It is assumed that the foot cover 300 shown in FIGS. 5 and 6 is all made of the same elastic material as the foot cover 100, but although not shown, the foot cover 300 is elastic on the upper trailing edge of the toe portion forming the opening. The narrow cloth 312 may be provided, and like the foot cover 200, it may be made of two or more different types of elastic cloth. Further, the stretchable narrow cloth 312 and the stretchable narrow cloth 316 may be the same cloth as or different from the cloth of the toe portion 302, the sole portion 304, the side side portion 306 and the heel portion 308. ..

Summarizing the above, the foot cover according to this embodiment is
(1) A foot in which the stretchable narrow cloth 116 provided on the upper edge of the side portion forming the opening is the same cloth, and the stretchable narrow cloth is not provided on the upper trailing edge of the toe portion 102. Cover 100 (FIGS. 1, 2),
(2) The stretchable narrow cloth 216 provided on the upper edge of the side portion 206 forming the opening is not the same cloth, and the stretchable narrow cloth is provided on the upper trailing edge of the toe portion 202. No foot cover 200 (Figs. 3 and 4),
(3) The stretchable narrow cloth 316 provided on the upper edge of the side portion 306 forming the opening is the same cloth, and the stretchable narrow cloth 312 is provided on the upper trailing edge of the toe portion 302. Foot cover 300 (Figs. 5 and 6),
(4) A foot cover in which the elastic narrow fabric provided on the upper edge of the side portion forming the opening is not the same fabric, and the elastic narrow fabric is provided on the upper trailing edge of the toe portion. (Not shown).

The features common to these foot covers 100, 200, and 300 will be described in detail below with reference to FIG. 9 (this FIG. 9 does not show the stretchable narrow cloth 312).
As shown in FIG. 9, with respect to the foot covers 100, 200, 300, the elasticity provided on the upper edges of the side portions 106, 206, 306 in a lateral view when the foot covers 100, 200, 300 are worn. The narrow cloth 116, 216, and 316 are characterized in that the angle α formed by the longitudinal direction and the opening cross section (the cross section is described by LL) into which the toe is inserted is substantially a right angle. This also means the angle formed by the longitudinal direction of the stretchable narrow fabrics 116, 216, 316 and the upper trailing edges of the toe portions 102, 202, 302 (same as the cross section described in LL). It can be said that α is approximately a right angle. Further, in particular, regarding the foot cover 300, the foot cover 300
It is formed by the longitudinal direction of the elastic narrow fabric 316 provided on the upper edge of the side side portion 306 and the elastic narrow fabric 312 provided on the trailing edge of the toe portion 302 in the lateral view when worn. The angle α is approximately a right angle.

As described above, in the foot covers 100, 200, and 300, since the above-mentioned angle α is substantially a right angle, as shown by the arrow in FIG. 9, the toes are perpendicular to the surface indicated by LL. The force that pulls the part backward acts greatly.
On the other hand, when the flat rubber is provided along the entire circumference of the peripheral edge of the opening as in Patent Document 2, the flat rubber is prevented from wrapping around from the instep to the ankle and shifting the foot cover. However, in this case, since the flat rubber acts to narrow the ankle, the force acting by the flat rubber is divided into a force for pulling the tip of the toe backward and a force for pulling it upward. Therefore, when the flat rubber and the stretchable narrow cloth 316 have the same degree of elasticity, the force for pulling the toe portion backward is smaller for the flat rubber, and the force for pulling the toe portion backward is smaller.

On the other hand, in the foot cover according to the present embodiment, since the angle α is substantially right angle, the force acting by the elastic narrow fabrics 116, 216, and 316 is (the toe portion is moved backward by the component force. Everything acts as a force that pulls the tip of the toe backwards (rather than acting as a pulling force). Therefore, the toe portions 102, 202, and 302 are strongly pulled backward. Therefore, the foot cover does not come off or the wearing position does not shift when walking or taking off and putting on the pumps P.

Further, regarding the foot covers 100 and 200, the elastic narrow cloth is not provided on the upper trailing edge of the toe portions 102 and 202. Therefore, compared to a foot cover (foot cover disclosed in Patent Document 2) in which one flat rubber is provided along the entire circumference of the opening, the opening is sufficiently provided when the foot covers 100 and 200 are worn. Easy to open and wear.
Further, regarding the foot cover 300, although the elastic narrow cloth 312 is provided on the upper trailing edge of the toe portion 302, one flat rubber is provided along the entire circumference of the opening (Patent Document). Compared with the foot cover disclosed in 2), when the foot cover 300 is worn, the opening is sufficiently opened and it is easy to wear.

The foot cover according to the present embodiment having such characteristics further exhibits the following effects.
10 (A) and 10 (B) show sideways sectional views when shoes having different heel heights (pumps P (1) and P (2)) are worn. The pumps P (2) of FIG. 10 (B) have a higher heel height than the pumps P (1) of FIG. 10 (A).

No matter what kind of shoes (pumps), the area from the tip (at least near the base of the toes) to the front of the arch is flat (shown as a flat part of the pumps). If such a flat portion of the pump is not formed, the entire inner surface of the pump has an oblique shape and lacks stability, so that it is not possible to walk stably. Therefore, any shoe (with or without heel) has this flat portion.

On the other hand, in the open cross section (upper trailing edge of the toe portion) of the toe portions 102, 202, 302 of the foot covers 100, 200, 300 according to the present embodiment, the pumps have a wide opening, so that the pumps can be used. The length is only about the front half of the flat part of the pump (the length up to the base of the toes) so that the foot cover cannot be seen when wearing it. Therefore, the angle of the opening cross section (upper trailing edge of the toe portion) indicated by LL with respect to the horizontal plane is the same regardless of the pump, and further, the opening cross section indicated by LL (the opening cross section). The angle α formed by the upper trailing edge of the toe portion) and the elastic narrow cloth 116, 216, 316 realizes a substantially right angle regardless of the pumps P.

Thus, whether the pumps P (1) are worn as shown in FIG. 10 (A) or the pumps P (2) are worn as shown in FIG. 10 (B), the angle is increased. Since α is substantially at a right angle, a force that pulls the toe portions 102, 202, and 302 backward greatly acts in the direction perpendicular to the opening cross section (upper trailing edge of the toe portion) indicated by LL. become.
Therefore, in the foot covers 100, 200, and 300 according to the present embodiment, the toe portions 102, 202, and 302 are strongly pulled backward even if the shoes have different heel heights. Therefore, no matter what kind of pumps are worn, the foot cover will not come off or the wearing position will not be displaced when walking or taking off and putting on the pumps.

When the flat rubber is provided along the entire circumference of the peripheral edge of the opening as in Patent Document 2, the form in which the flat rubber wraps around from the instep to the ankle changes depending on the heel height of the pumps. Therefore, it is not possible to prevent the foot cover from slipping in response to pumps of various heel heights. That is, since this flat rubber is genuine (because one genuine flat rubber is provided over the entire peripheral edge of the opening), the radius of the portion from the side surface portion to the toe portion becomes large. Depending on the heel height of the pumps, wrinkles may occur in this part, and sufficient tensile force cannot be expressed.

As described above, the foot cover disclosed in Patent Document 2 cannot cope with pumps of various heel heights, and the force for pulling the toe portion backward becomes small, so that when walking and when putting on and taking off the pumps, It is not possible to prevent the foot cover from coming off or being out of position.
In any of the foot covers, the stretchable narrow cloth is joined to the foot cover cloth by a heat press device.

As described above, according to the foot cover according to the present embodiment, in the lateral view when the foot cover is worn, the longitudinal direction of the elastic narrow cloth provided on the upper edge of the side side portion and the toe portion. The angle α formed by the upper trailing edge (the cross section of the opening into which the toe is inserted) is formed to be substantially a right angle. For this reason, the force that pulls the toe portion backward is large, and it is possible to prevent the foot cover from coming off or the wearing position from being displaced when walking or taking off and putting on the pumps. Further, since one elastic narrow cloth is not provided along the entire circumference of the opening, the opening is sufficiently opened and it is easy to wear when wearing the foot cover. Further, even if the pumps have different heel heights, it is possible to prevent the foot cover from coming off or the wearing position from being displaced when walking or taking off and putting on the pumps.

<Second embodiment>
Hereinafter, the foot cover 400 according to the second embodiment of the present invention will be described. The foot cover 400 according to the present embodiment includes the soles 104, 204, 304, side sides 106, 206, 306 and heels of the foot covers 100, 200, 300 according to the first embodiment described above. The difference is that 108, 208 and 308 are not provided. Other than that, since it is the same as that of the first embodiment, the part overlapping with the above description will not be repeated here.

11 and 12 show the foot cover 400 according to the second embodiment of the present invention. 11 is an overall perspective view of the foot cover 400, FIG. 12 is a perspective view of the foot cover 400 turned inside out, and both of FIGS. 11 and 12 show the foot cover 400 on the wearer's foot F. It is supposed to be worn.
As shown in these figures, the foot cover 400 is a foot cover that covers the toe, and is joined to the tubular toe portion 402 that covers the toe tip and the left and right sides of the toe portion 402, respectively, and is attached to the heel when worn. It is formed of a loop-shaped elastic member 416 to be locked. Elastic member 416
A heel non-slip 418 formed of a thin sheet such as silicon resin is provided at a portion in contact with the heel of the heel. As a result, the adhesion of the foot F to the heel can be improved and the foot cover 400 can be prevented from being displaced from the foot F. Further, the toe portion 402 is formed of a thin sheet such as silicon resin on the side opposite to the side where the foot F contacts (the side that contacts the inner sole of the pump when the pump is worn), and the sole portion is provided with a non-slip. It is also preferable. As a result, the adhesion to the inner bottom of the pump can be improved and the position of the foot cover 400 in the pump can be prevented from shifting.

The fabric of the elastic member 416 may be the same elastic fabric such as pantyhose as the toe portion 402, or may be a different fabric. Further, although the elastic member 416 is in the shape of a strip, it may be in the shape of a string. In this case, if it is difficult to provide the heel non-slip 418, it is preferable to form the string-shaped elastic member 416 with a rubber member (rubber string) coated with a silicon resin.

In such a foot cover 400, as shown in FIG. 13, formed by the longitudinal direction of the elastic member 416 and the upper trailing edge of the toe portion 402 in the lateral view when the foot covers 100, 200, and 300 are worn. The angle α to be formed is a substantially right angle. This is the same as FIG. 9 described above, except that it does not have a sole, sides and heels. Then, as described with reference to FIG. 10, even if the foot cover 400 has different heel heights, the foot cover may come off or the wearing position may be displaced when walking or taking off and putting on the pumps. It is possible to prevent chilling.

As described above, the foot cover 400 according to the present embodiment can also exhibit the same effects as the foot covers 100, 200, and 300 according to the first embodiment described above.
It should be noted that the embodiments disclosed this time are exemplary in all respects and are not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

The present invention is suitable for a foot cover worn with bare feet, the opening is sufficiently open when the foot cover is worn, and the foot cover is easily worn when walking or when the pumps are taken off or put on. It is particularly preferable in that it does not shift.
