Description

The present invention relates to a foot cover that hides inside shoes such as pumps (primarily women's shoes with a wide open instep) and becomes invisible when worn. To provide a foot cover that is less likely to come off or shift its position even when the foot is moved.

Wearing shoes such as pumps with bare feet has become established as fashion. In this case, if the pumps and the soles of the feet are in direct contact, sweat generated on the feet will cause the inside of the shoes to become stuffy, causing discomfort.
Therefore, we proposed a thin foot cover that covers the sole of the foot, including the toes and heel, and exposes the instep and ankle, and has a large opening cut to prevent it from being exposed from the pumps when worn. has been done. If you wear pumps with this foot cover, it will look like you are wearing pumps on bare feet, but since the foot cover is between the sole of your foot and the pumps, the inside of your shoes will get stuffy due to sweat. It is possible to prevent this from happening.

Note that such a foot attachment device is referred to as a foot cover in this specification, but may also be referred to as a sock cover, inner sock, nude sock, cover sock, or the like.
Since the opening of such foot covers is cut wide so as not to be exposed from the pumps, friction during walking may cause the foot covers to shift, slip off, or slip. On the other hand, if the opening is made too small, it will be exposed through the pumps. Foot covers developed in view of such problems are disclosed in the following prior art documents.

Japanese Unexamined Patent Publication No. 10-292206 (Patent Document 1) discloses that the foot cover may come off from bare feet due to friction between the pumps and the foot cover when walking, or the foot cover may come off when putting on or taking off the pumps, or the position of the foot cover may be incorrect. A foot cover is disclosed in which a friction imparting body is attached to the inner surface of a heel contact part in order to prevent the foot cover from slipping.
Utility Model Registration No. 3165733 (Patent Document 2) discloses that when a rubber cord is provided along the periphery of the opening of the foot cover disclosed in Patent Document 1, the rubber cord digs into the foot, so the rubber cord does not fit into the foot. In view of the problems of the laces forming, causing pain, and being uncomfortable to wear, we created a band-like elastic band with flat rubber along the periphery of the opening so that one side is in contact with the foot. Disclosed is a foot cover having a portion formed therein.

Japanese Patent Application Publication No. 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, and in this case, the foot cover may come off when walking or putting on and taking off the pumps, or the position of the foot cover may shift. Relaxing. 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 sufficiently wide when wearing the foot cover. In addition to being difficult to put on because they do not open, there is also the problem that, similar to the foot cover disclosed in Patent Document 1, the foot cover may come off or be misplaced when putting on or taking off the pumps.

In particular, in conventional foot covers, when the sole part and heel part are made of separate fabrics and those fabrics are sewn, the seam may get caught on the sole or heel, and when walking or wearing pumps. When putting on and taking off shoes, the foot cover may come off or the shoe may be misplaced, and the seams may make it difficult or uncomfortable to wear.
The present invention was developed in view of the above-mentioned problems of the prior art, and its purpose is to prevent the foot cover from falling off when walking or putting on and taking off pumps due to the seams, To provide a foot cover that does not shift and is not difficult or uncomfortable to wear due to seams.

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 the present invention is a foot cover that covers the sole of the foot including the toe and the heel and exposes the instep and ankle, and the foot cover covers the sole of the foot, the sides, the heel, and the toe that covers the toe. A first elastic knitted fabric forming the side portions, the heel portion, and the toe portion, and a second elastic knitted fabric forming the sole portion are joined with an adhesive tape. Therefore, it is characterized by being formed into a three-dimensional shape without seams.

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

According to the foot cover of the present invention, the seam prevents the foot cover from coming off or shifting when walking or putting on and taking off pumps. It is possible to prevent shoes from being difficult or uncomfortable to wear due to

FIG. 1 is an overall perspective view of a foot cover according to an embodiment of the present invention. FIG. 2 is an overall perspective view of the foot cover of FIG. 1 turned over; They are a three-sided view (A) of the foot cover of FIG. 1 and a three-sided view (B) of the foot cover of FIG. 2. FIG. 2 is a developed view of the foot cover of FIG. 1;

Hereinafter, a foot cover according to an embodiment of the present invention will be described in detail based on the drawings. Note that there are various foot cover structures, and the present invention is not limited to a specific structure, and can be applied to any foot cover structure as long as it has the features described below. Basically, it does not matter what type of fabric, the pattern of the fabric, and the method of joining the fabric make up the foot cover. Therefore, the structure of the foot cover shown below is merely an example.

The fabric that forms this foot cover is bare jersey (bare jersey), which is knitted using thread (covered yarn, etc.) that is made by wrapping threads of other materials (cotton, wool, etc.) around a polyurethane thread. Plain knitted fabric), tricot (warp knitted fabric knitted by a tricot machine, which is a type of warp knitting machine), fabric for pantyhose (knitted fabric containing polyurethane thread and nylon thread), etc. are preferably used. In particular, among these, bare top has (1) excellent elasticity, (2) good shape stability and little change in shape after washing, and (3) soft texture and excellent fit. (4) It is less likely to wrinkle or crease, (5) it has a porous structure, so it is breathable, and (6) when it contains cotton, it is good to the touch and absorbs moisture, making it preferable for foot covers.

Furthermore, the foot cover according to the present embodiment is a foot cover that covers the sole of the foot including the toe and the heel and exposes the instep and ankle, and covers the sole, side, heel, and toe. Formed at the tip of the toe. Further, although not limited to this, the foot cover shown below is suitable for both left and right use, and is preferred in that it is possible to avoid wearing the left and right shoes by mistake. Note that if the foot cover is not for both left and right feet, the foot cover for the left foot and the right foot have symmetrical shapes.

The characteristic feature is that the first stretchable knitted fabric forming the sides, heel, and toe part and the second stretchable knitted fabric forming the sole are joined with 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 each a planar knitted fabric with a predetermined peripheral edge shape, and the peripheral edge of the second elastic knitted fabric and the first elastic knitted fabric are It is formed by joining a part of the periphery of the flexible knitted fabric with an adhesive tape. There are no limitations to the joining of fabrics, but there are adhesive tapes in which an adhesive is applied to one side of a strip-shaped member, and when heated, the adhesive melts and the fabric is thermally bonded. Preferably. Note that this joining includes methods such as thermocompression bonding, thermal welding, and thermal fusion.

FIG. 1 shows an overall perspective view of a foot cover 100 according to an embodiment of the present invention, FIG. 2 shows an overall perspective view of the foot cover 100 turned over, and FIG. 3A shows the state shown in FIG. 1 (not turned over). ) is a three-sided view (a front view seen from the front of the toe, a side view, and a back view seen from the back of the heel) of the foot cover 100 in the state shown in FIG. A developed view (paper pattern) of this foot cover 100 is shown in three views (a front view seen from the front of the toe, a side view, and a rear view seen from the back of the heel). Here, FIG. 1, FIG. 2, and FIG. 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 stretchable fabric such as tricot, it will be in a shrunken state unless shown in the drawings, making it difficult to understand the shape. Since this is difficult, the above assumption is made. In particular, in FIG. 3, the sole portion 104 is depicted to be more visible than when actually worn, so that the characteristics of the foot cover 100 can be easily understood.

This foot cover 100 is a foot cover that covers the sole of the wearer's foot F, including the toes and heel, and exposes the instep and ankle. This foot cover 100 is made of thin stretchable fabric (fabric such as tricot) with a large opening that is the opening of the shoe so that it will not be exposed from the pumps when worn. Here, "not being exposed from the pumps when worn" includes the foot cover 100 being hidden by the pumps and becoming 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 foot sole portion 104B, and a heel side sole portion 104C), a side portion 102B, and a heel portion 102C. Further, an opening for inserting and removing the foot is provided on the upper and lower opposite sides of the sole portion 104. A narrow stretchable fabric 114 is provided on the inside of the foot cover 100 (the side that touches the foot F: the skin side) over the entire circumference of the upper edge of this opening. When wearing this foot cover 100, if you stretch the narrow elastic fabric 114, the opening will open wide, making it easier to wear. Since the portion is small, the foot cover 100 does not come off when walking. Note that the narrow stretchable fabric 114 may be provided on the outside 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 this opening. Note that the stretchable narrow fabric 114 may be provided on a part of the upper edge of the opening instead of all around it, or may be provided intermittently rather than continuously.

Further, on the upper edge of the heel portion 102C of this foot cover 100, a heel portion anti-slip formed of a thin transparent sheet such as silicone resin is provided on the inside of the foot cover 100 (the side that the foot F contacts: the skin side). 116 is also preferable. Therefore, in the heel portion 102C, a stretchable narrow fabric 114 is provided on the upper side (inside) of the fabric (more specifically, the first elastic knitted fabric 120), and a heel adhesive tape, which will be described later, is provided on the upper side (inside) of the fabric (more specifically, the first elastic knitted fabric 120). 106 is provided, and a heel anti-slip 116 is further provided on the upper side (inside) thereof. Thereby, the close contact with the heel of the foot F can be improved, and the foot cover 100 can be further prevented from shifting from the heel of the foot F. Note that this heel anti-slip 116 is not an essential component in the foot cover according to the present invention.

The feature of this foot cover 100 is that, as shown in the developed view (pattern) of FIG. The part 102 is composed of a first elastic knitted fabric 120, which is a piece of fabric with a predetermined peripheral shape, and the sole part 104 has a predetermined peripheral shape (roughly equivalent to the sole shape). The point is that the second elastic knitted fabric 140 is a single piece of fabric. That is, 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. Note that there may be three (or more) pieces of fabric instead of two.

Then, the first elastic knitted fabric 120 and the second elastic knitted fabric 140 are brought close to each other 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 with each other,
The upper adhesive line 108B of the side part 102B of the first elastic knitted fabric 120 and the lower adhesive line 108A of the central sole part 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 in contact with each other,
The abutting portions are joined with one bottom adhesive tape 108.

That is, the lower adhesive line 108A, which is the (entire) periphery of the second elastic knitted fabric 140, and the upper adhesive line 108B, which is a part of the periphery of the first elastic knitted fabric 120 , are connected to one This foot cover 100 is formed by joining 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 heel left side adhesive line 106A and the heel right side adhesive line 106B are brought close to each other in the direction of arrow Y in FIG. It is joined.

In this case, the heel adhesive tape 106 and the sole adhesive tape 108 have an adhesive applied to 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 and the fabrics are thermally bonded and joined. Further, the heel adhesive tape 106 and the sole adhesive tape 108 are thermally bonded from the back side of the foot cover 100 (the side that contacts the foot F: the skin side) to join the fabric. However, the heel adhesive tape 106 and/or the sole adhesive tape 108 may be thermally 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 fabric. In this way, the toe portion 102A is made without seams.
A foot cover 100 is three-dimensionally formed, and includes a side portion 102B, a sole portion 104, and a heel portion 102C.

In this way, in this foot cover 100, the side parts 102 other than the sole part 104 are made of the first elastic knitted fabric 120, and the sole part 104 is made of the second elastic knitted fabric 140. In addition, when the sole and heel of conventional foot covers are sewn from separate fabrics, the seams that occur can get caught on the heel, causing the foot cover to fall off when walking or when putting on and taking off pumps. Problems such as misalignment can be avoided, and since there are no seams, the shoe is extremely comfortable to wear.

Furthermore, in the sole part 104, a sole anti-slip formed of a thin sheet of silicone resin or the like is provided on the side opposite to the side where the foot F comes into contact (the side that comes into contact with the inner sole of the pumps when the pumps are worn). is also preferable. This improves the adhesion to the inner sole of the pumps and prevents the foot cover 100 from shifting within the pumps. Note that this anti-slip foot sole is also not an essential feature of the foot cover according to the present invention.

In addition, in this foot cover 100, a first elastic knitted fabric 120 forming the side part 102 other than the sole part 104 and a second elastic knitted fabric 140 forming the sole part 104 form this foot cover 100. and the stretchable narrow fabric 114 may be made of the same common fabric. That is, except for the heel adhesive tape 106 and the sole adhesive tape 108, this foot cover 100 may be entirely formed of the same stretchable fabric (tricot, etc.). In addition, in this foot cover 100, the stretchable narrow fabric 114 is heated by a heat press device so that an adhesive applied to the stretchable narrow fabric 114 melts and is thermally bonded to the fabric. has been done.

Further, in the foot cover 100, a first elastic knitted fabric 120 forming the side portion 102 other than the sole portion 104 forming the foot cover 100, and a second elastic knitted fabric 140 forming the sole portion 104. There is no problem even if the first stretch knitted fabric 120, second stretch knitted fabric 140, and stretchable narrow width fabric 114 are not made of the same fabric. .

As described above, according to the foot cover 100 according to the present embodiment, the first stretchable knitted fabric 120 forming the side part 102 other than the sole part 104 and the second elastic knitted fabric forming the sole part 104 are combined. The base 140 is each made of one piece of fabric, and these are joined with a bottom adhesive tape 108, and are joined with a heel adhesive tape 106 in the first elastic knitted fabric 120 to form a heel portion 102C. has been done. For this reason, the seam gets caught on the heel, which is a problem that occurs when the sole part and heel part are sewn with separate fabrics like in conventional foot covers. You can avoid problems such as shoes falling off or misaligned. Furthermore, this foot cover 100 has no seams at all, making it extremely comfortable to wear.

It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered restrictive. The scope of the present invention is indicated by the claims rather than the above description, and it is intended that all changes within the meaning and range equivalent to the claims are included.

The present invention is suitable for foot covers worn barefoot, and has seams to prevent the foot covers from falling off or shifting when walking or putting on and taking off pumps, and This is particularly preferable because the seams do not make it difficult or uncomfortable to wear.
