Description

The present invention relates to a foot cover that hides and disappears inside shoes such as pumps (mainly women's shoes with a wide instep that is a shoe opening) when worn, and is particularly easy to wear and comfortable to wear. It relates to a foot cover that is less likely to come off or be displaced even by the operation of.

Wearing shoes such as pumps on bare feet is established as fashion. In this case, if the pumps are in direct contact with the soles of the feet, the sweat generated on the feet will make the inside of the shoes stuffy and uncomfortable.
Therefore, we propose a thin foot cover that covers the toe and the sole of the foot, including the heel, and exposes the instep and the ankle, and has a wide cut opening so that it is not exposed from the pump when worn. It is 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 interposed between the soles of your feet and the pumps, so the inside of your shoes will get stuffy due to sweat. You can prevent it from being lost.

In addition, although such a footwear is described as a foot cover in this specification, it may also be described as a sock cover, inner socks, nude socks, cover socks, and the like.
Since such a foot cover has a large opening so that it is not exposed from the pumps, friction during walking may cause the foot cover to slip out of position or come off. On the other hand, if the opening is made smaller, it will be exposed from the pumps. Foot covers developed in view of such problems are disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 10-292206 (Patent Document 1) discloses that the foot cover may come off from the bare feet due to friction between the pumps and the foot cover during walking, or the foot cover may come off when putting on and taking off the pumps, or the foot cover may come off in an improper position. Disclosed is a foot cover in which a friction imparting body is attached to the inner surface of a heel contact portion in order to prevent slippage.
Japanese Utility Model Registration No. 3165733 (Patent Document 2) discloses that if a rubber cord is provided along the periphery of the opening of the foot cover disclosed in Patent Document 1, the rubber cord will bite into the foot, causing the rubber to be worn on the foot. In consideration of the problems of the straps sticking to the mold, causing pain, and being uncomfortable to wear, flat rubber is provided along the periphery of the opening so that one side is in contact with the foot. A sectioned foot cover is disclosed.

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

Here, the friction imparting body of the foot cover disclosed in Patent Document 1 may not be sufficient in some cases. Relax. With the flat rubber disclosed in Patent Document 2, since the flat rubber is provided over the entire periphery of the opening (depending on the stretchability of the flat rubber), the opening is sufficiently wide when the foot cover is put on. In addition to being difficult to put on without opening, there is also the problem that, like the foot cover disclosed in Patent Document 1, the foot cover may come off when putting on or taking off the pumps, or the position of the shoes may shift.

In particular, in conventional foot covers, when the sole and heel are made of separate fabrics and sewn together, the seams may get caught on the sole or heel, which may cause problems when walking or wearing pumps. When putting on and taking off shoes, the foot cover may come off, the position of the shoes may shift, and the seams may make the shoes difficult to wear or uncomfortable to wear.
The present invention has been developed in view of the above-mentioned problems of the prior art. To provide a foot cover which does not cause slippage and does not make it difficult to wear or uncomfortable to wear due to the presence of seams.

In order to achieve the above object, the foot cover according to the present invention employs the following technical measures.
That is, the foot cover according to the present invention is a foot cover that covers the toe and the bottom of the foot including the heel and exposes the instep and the ankle, and comprises the sole, the lateral side, the heel and the toe that covers the toe. A first stretchable knitted fabric that forms the side portion, the heel portion, and the toe portion, and a second stretchable knitted fabric that forms the sole portion are joined with an adhesive tape. Therefore, it is characterized by being formed into a three-dimensional shape without seams.

Preferably, each of the first elastic knitted fabric and the second elastic knitted fabric is a planar knitted fabric having a predetermined peripheral edge shape, and the peripheral edge of the second elastic knitted fabric and the It can be configured such that it is formed by joining a portion of the peripheral edge of the first elastic knitted fabric with an adhesive tape. In this case, the portion covering the heel may be formed by joining portions of the first elastic knitted fabric with an adhesive tape.

According to the foot cover of the present invention, it is possible to prevent the foot cover from coming off or slipping out of position when walking or putting on and taking off pumps due to the presence of the seams. It is possible to prevent it from being difficult to wear or uncomfortable to wear due to the presence of

Hereinafter, foot covers according to embodiments of the present invention will be described in detail with reference to the drawings. There are various foot cover structures, and the present invention is not limited to a specific structure, and any foot cover structure can be used as long as it has the features described later. , the type of fabric that constitutes the foot cover, the paper pattern of the fabric, and the joining method of the fabric are basically acceptable. Therefore, the structure of the foot cover itself shown below is merely an example.

In addition, the fabric that forms this foot cover is knitted using yarn (covered yarn, etc.) in which yarn of other materials (cotton, wool, etc.) is wound around a polyurethane yarn. Plain knitted fabric), tricot (warp-knitted fabric knitted by a tricot machine, which is a kind of warp knitting machine), pantyhose fabric (knitted fabric containing polyurethane yarn and nylon yarn), etc. are preferably used. In particular, the bare top is (1) excellent elasticity, (2) good shape stability and little change in shape after washing, and (3) soft texture and excellent fit. , (4) resistance to wrinkles and creases, (5) air permeability due to its porous structure, and (6) good touch and moisture absorbency when it contains cotton.

Furthermore, the foot cover according to the present embodiment is a foot cover that covers the toe and the sole including the heel and exposes the instep and the ankle, and covers the sole, the lateral side, the heel and the toe. Formed at the toe. In addition, although not limited, the foot cover described below is for both the left and right hands, which is preferable in that the right and left shoes are not mistakenly put on. In addition, when the foot cover is not common for both left and right feet, the left foot cover and the right foot cover have a symmetrical shape.

Characteristically, the first elastic knitted fabric forming the side edge portion, the heel portion and the toe portion and the second elastic knitted fabric forming the sole portion are joined with an adhesive tape. As a result, it is formed into a three-dimensional shape without seams. In particular, the first elastic knitted fabric and the second elastic knitted fabric are respectively planar knitted fabrics having a predetermined peripheral edge shape, and the peripheral edge of the second elastic knitted fabric and the first elastic knitted fabric It is formed by joining a part of the peripheral edge of the elastic knitted fabric with an adhesive tape. Although there is no limitation on such bonding of fabrics, it is an adhesive tape in which an adhesive is applied to one surface of a strip-shaped member, and when heated, the adhesive melts and the fabrics are thermally bonded and joined. preferably. Note that this bonding includes thermocompression bonding, heat welding, heat sealing, and the like.

FIG. 1 is an overall perspective view of the foot cover 100 according to the embodiment of the present invention, FIG. 2 is an overall perspective view of the foot cover 100 turned over, and FIG. ) of the foot cover 100 (a front view viewed from the front of the toe, a side view and a rear view viewed from the rear of the heel) are shown in FIG. Three views (a front view, a side view, and a rear view seen from the rear of the heel) are shown, and FIG. Here, FIGS. 1, 2 and 3 assume a state in which the foot cover 100 is worn on the foot F of the wearer. That is, since the foot cover 100 according to the embodiment of the present invention is formed of a stretchable fabric such as tricot, it will be in a contracted state when not shown in the drawings assuming such a case. is difficult, the above assumption is made. In particular, in FIG. 3, in order to facilitate understanding of the features of the foot cover 100, the sole portion 104 is shown more clearly than when the foot cover is actually worn.

This foot cover 100 is a foot cover that covers the toe and sole including the heel of the wearer's foot F and exposes the instep and the ankle. The foot cover 100 is made of a thin stretchable fabric (a fabric such as tricot) with a large opening that is cut so that the foot cover 100 is not exposed from the pumps when worn. Here, not being exposed from the pumps when worn includes the fact that the foot cover 100 is hidden by the pumps and becomes invisible or difficult to see.

The foot cover 100 is formed of a toe portion 102A, a sole portion 104 (more specifically, a toe-side sole portion 104A, a central sole portion 104B and a heel-side sole portion 104C), side portions 102B and a heel portion 102C. An opening for putting in and taking out the foot is provided on the opposite side of the sole 104 . An elastic narrow cloth 114 is provided inside the foot cover 100 (the side with which the foot F contacts: the skin side) along the entire circumference of the upper edge of the opening. When the elastic narrow cloth 114 is stretched when the foot cover 100 is put on, the opening is widened, making it easy to wear. Since the portion is small, the foot cover 100 does not come off during walking. It should be noted that the stretchable narrow fabric 114 may be provided on the outer side of the foot cover 100 (the side opposite to the side where the foot F contacts: the shoe side) over the entire circumference of the upper edge of the opening. The stretchable narrow cloth 114 may be provided not on the entire circumference of the upper edge of the opening but on a part of the upper edge, or may be provided intermittently rather than continuously.

Further, on the upper edge of the heel portion 102C of the foot cover 100, on the inner side of the foot cover 100 (the side in contact with the foot F: the skin side), there is a heel anti-slip pad formed of a thin transparent sheet such as silicone resin. The provision of 116 is also preferred. Therefore, in the heel portion 102C, the elastic narrow fabric 114 is provided on the upper side (inside) of the fabric (more specifically, the first elastic knitted fabric 120), and the heel adhesive tape described later is provided on the upper side (inner side). 106 is provided, and a heel anti-slip 116 is further provided on the upper side (inner side) thereof. As a result, it is possible to further prevent the foot cover 100 from slipping off the heel of the foot F by enhancing the close contact with the heel of the foot F. It should be noted that the heel anti-slip 116 is not an essential component of the foot cover according to the present invention.

4, the toe portion 102A, the side portion 102B, and the heel portion 102C (that is, the side of the foot cover 100 other than the sole portion 104). The portion 102) is composed of a first elastic knitted fabric 120 that is a piece of fabric with a predetermined peripheral edge shape, and the sole portion 104 has a predetermined peripheral edge shape (generally equal to the sole shape). It is composed of the second elastic knitted fabric 140 which is one piece of fabric provided. That is, the side portion 102 other than the sole portion 104 is composed of the first elastic knitted fabric 120 , and the sole portion 104 is composed of the second elastic knitted fabric 140 . Note that the number of fabrics may be three (or more) instead of two.

Then, the first elastic knitted fabric 120 and the second elastic knitted fabric 140 are approached in the arrow X(1) direction and the arrow X(2) direction in FIG.
The upper adhesive line 108B of the toe portion 102A of the first elastic knitted fabric 120 and the lower adhesive line 108A of the toe-side sole portion 104A of the second elastic knitted fabric 140 are brought into contact,
The upper adhesive line 108B of the side portion 102B of the first elastic knitted fabric 120 and the lower adhesive line 108A of the central sole portion 104B of the second elastic knitted fabric 140 are brought into contact with each other,
The upper adhesive line 108B of the heel portion 102C of the first elastic knitted fabric 120 and the lower adhesive line 108A of the heel-side sole portion 104C of the second elastic knitted fabric 140 are brought into contact,
The abutting portion is joined with one bottom adhesive tape 108 .

That is, the lower adhesive line 108A, which is the (entire) peripheral edge of the second elastic knitted fabric 140, and the upper adhesive line 108B, which is a part of the peripheral edge of the first elastic knitted fabric 120, are combined into one. This foot cover 100 is formed by bonding with a bottom adhesive tape 108 . Note that the bottom adhesive tape 108 may be divided into two or more pieces.
Furthermore, in this first elastic knitted fabric 120, the left heel adhesive line 106A and the right heel adhesive line 106B are approached in the direction of arrow Y in FIG. are spliced.

In this case, the heel adhesive tape 106 and the sole adhesive tape 108 are coated with an adhesive on one side (fabric (first elastic knitted fabric 120 and second elastic knitted fabric 140) side), and are heated. As a result, the adhesive applied to the heel adhesive tape 106 and the sole adhesive tape 108 is melted to thermally bond the fabrics. Also, the heel adhesive tape 106 and the sole adhesive tape 108 are heat-bonded from the back side of the foot cover 100 (the side with which the foot F contacts: the skin side) to join the fabrics. However, the heel adhesive tape 106 and/or the sole adhesive tape 108 may be heat-bonded from the front side of the foot cover 100 (the side opposite to the side where the foot F contacts: the shoe side) to join the fabrics. In this manner, the foot cover 100 having the toe portion 102A, the side portion 102B, the sole portion 104, and the heel portion 102C without seams is three-dimensionally formed.

Thus, in the foot cover 100, the side portions 102 other than the sole portion 104 are made of the first elastic knitted fabric 120, and the sole portion 104 is made of the second elastic knitted fabric 140. In addition, unlike conventional foot covers, when the sole and heel are sewn with different fabrics, the seams that occur are caught in the heel, causing the foot cover to come off or slip off when walking or putting on and taking off pumps. Problems such as misalignment can be avoided, and since there are no seams, it is extremely comfortable to wear.

Furthermore, in the sole part 104, the side opposite to the side in contact with the foot F (the side in contact with the inner sole of the pump when the pump is worn) is provided with a non-slip sole made of a thin sheet such as silicone resin. is also preferred. As a result, it is possible to prevent the position of the foot cover 100 from shifting within the pump by enhancing the close contact with the inner sole of the pump. It should be noted that this foot sole non-slip is also not an essential component of the foot cover according to the present invention.

In this foot cover 100, a first elastic knitted fabric 120 forming the side portion 102 other than the sole portion 104 and a second elastic knitted fabric 140 forming the sole portion 104, which form the foot cover 100. , and the stretchable narrow width fabric 114 may be formed of the same co-fabric. That is, except for the heel adhesive tape 106 and sole adhesive tape 108, the foot cover 100 may be made entirely of the same elastic fabric (such as tricot). In the foot cover 100, the stretchable narrow cloth 114 is heated by a heat press, and the adhesive applied to the stretchable narrow cloth 114 is melted and bonded to the cloth by heat bonding. It is

In the foot cover 100, the first elastic knitted fabric 120 forming the side portion 102 other than the sole portion 104 forming the foot cover 100, and the second elastic knitted fabric 140 forming the sole portion 104. may be formed without the same fabric, and the first elastic knitted fabric 120, the second elastic knitted fabric 140, and the elastic narrow fabric 114 may not be formed with the same fabric. .

As described above, according to the foot cover 100 according to the present embodiment, the first elastic knitted fabric 120 forming the side portion 102 other than the sole portion 104 and the second elastic knitted fabric forming the sole portion 104 The ground 140 is composed of one piece of fabric respectively, and they are joined with the sole adhesive tape 108, and joined with the heel adhesive tape 106 in the first elastic knitted fabric 120 to form the heel portion 102C. It is For this reason, when the bottom part and the heel part are sewn with different fabrics as in conventional foot covers, the seams get caught on the heel and the foot cover becomes difficult to wear when walking or putting on and taking off pumps. It is possible to avoid the problem of slipping off or shifting of the wearing position. Furthermore, according to this foot cover 100, there are no seams at all, so that it is extremely comfortable to wear.

It should be noted that the embodiments disclosed this time should be considered as examples in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the scope and meaning of equivalents of the scope of the claims.

INDUSTRIAL APPLICABILITY The present invention is suitable for a foot cover to be worn with bare feet, and prevents the foot cover from coming off or slipping out of position when walking or putting on and taking off pumps due to seams, and It is particularly preferable in that it is not difficult or uncomfortable to wear due to the presence of seams.
