Description

The present invention relates to a foot cover that is hidden behind shoes such as pumps (mainly women's shoes with a wide open instep) when worn, and is particularly easy to wear and comfortable to wear, such as walking. It is related to the foot cover that is less likely to come off or shift due to the movement of.

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 put on 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, it feels painful, 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

Here, 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 be displaced when walking or taking off and putting on the pumps. Relax. 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.

In particular, in a conventional foot cover, if the sole and heel are made of separate fabrics and those fabrics are sewn, the seams may get caught on the sole or heel, and when walking or pumps. There are problems that the foot cover comes off or the position of the foot is misaligned when putting on and taking off, and that it is difficult or uncomfortable to wear due to the seams.
The present invention has been developed in view of the above-mentioned problems of the prior art, and an object thereof is that the foot cover may come off or the wearing position when walking or taking off and putting on the pumps due to the seams. The purpose is to provide a foot cover that does not slip off and is not difficult or uncomfortable to wear due to the 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 toe and the sole including the heel and exposes the instep and the ankle, and is a toe that covers the sole, the side, the sole, and the toe. The first elastic knitted fabric formed by the portions and forming the side surface 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 characterized in that it is formed into a three-dimensional shape without any seams.

Preferably, the first stretchable knitted fabric and the second stretchable knitted fabric are planar knitted fabrics having a predetermined peripheral shape, respectively, and are the peripheral edges of the second elastic knitted fabric. It can be configured to be formed by joining a part of the peripheral edge of the first elastic knitted fabric with an adhesive tape. In this case, it is possible to form a portion covering the heel by joining the parts of the first elastic knitted fabric to each other 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 being misaligned when walking or taking off and putting on the pumps due to the seams, and the seams. It is possible to prevent it from being difficult or uncomfortable to wear because of the presence.

It is an overall perspective view of the foot cover which concerns on embodiment of this invention. It is the whole perspective view which turned over the foot cover of FIG. 3A and 3B are a three-view view of the foot cover of FIG. 1 and FIG. 2B is a three-view view of the foot cover of FIG. It is a development view of the foot cover of FIG.

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. Basically, it does not matter what kind of fabric constitutes the foot cover, the pattern of the fabric, and the method of joining the fabric. Therefore, the structure of the foot cover shown below is merely an example.

The fabric that forms this foot cover is knitted using bare heaven (bare heaven: a thread (covered yarn, etc.) wound with threads of other materials (cotton, wool, etc.) around a polyurethane thread. Flat knitted fabric), tricot (warp knitted fabric knitted by a tricot machine which is a kind of warp knitting machine), fabric for pantyhose (knitted fabric containing polyurethane yarn and nylon yarn) and the like are preferably used. In particular, among these, bare heaven 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 hard to wrinkle and crease, (5) It has a porous structure and is breathable, and (6) When it contains cotton, it has good touch and hygroscopicity, which is preferable for a foot cover.

Further, the foot cover according to the present embodiment is a foot cover that covers the toes and the sole including the heel and exposes the instep and the ankle, and covers the sole, the side surface, the heel, and the toe. It is formed at the tip of the toe. Further, although not limited, the foot covers shown below are shared on the left and right sides, and since they are shared on the left and right sides, it is preferable that the left and right sides are not mistakenly worn. If the foot cover is not shared on the left and right sides, the left foot cover and the right foot cover have symmetrical shapes.

And, characteristically, the first elastic knitted fabric forming the side surface 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 any seams. In particular, the first elastic knitted fabric and the second elastic knitted fabric are planar knitted fabrics having a predetermined peripheral shape, respectively, and the peripheral edge of the second elastic knitted fabric and the first elastic knitted fabric, respectively. It is formed by joining a part of the peripheral edge of the knitted fabric with an adhesive tape. The bonding of such fabrics is not limited, but is an adhesive tape in which an adhesive is applied to one surface of a strip-shaped member, and the adhesive melts when heated to heat-bond the fabrics for bonding. It is preferable to do. In addition, this joining includes the one by thermocompression bonding, the one by heat welding, the one by heat welding and the like.

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 inside out, and FIG. 3A is a state of FIG. 1 (not turned inside out). 3) (front view seen from the front of the toe, side view and rear view seen from the rear of the heel) of the foot cover 100 in FIG. 3 (B), and the foot cover 100 in the state of FIG. Three views (front view seen from the front of the toe, side view and rear view seen from the rear of the heel) are shown, and FIG. 4 shows a developed view (pattern) of the foot cover 100. Here, FIGS. 1, 2 and 3 assume a state in which the foot cover 100 is worn on the wearer's foot F. That is, since the foot cover 100 according to the embodiment of the present invention is made of an elastic fabric such as a tricot, if it is not shown in this way, it will be in a shrunk state and the shape will be understood. Is difficult, so it is assumed as described above. In particular, in FIG. 3, in order to easily understand the characteristics of the foot cover 100, the sole portion 104 is drawn so as to be clearly visible compared to the state in which the foot cover 100 is actually worn.

The foot cover 100 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. The foot cover 100 is made of a thin elastic fabric (fabric such as tricot) in which the opening which is the opening is largely cut so as not to be exposed from the pumps when worn. Here, the fact that the foot cover 100 is not exposed from the pump when worn includes that the foot cover 100 is hidden by the pump 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), a side side portion 102B and a heel portion 102C. An opening for putting the foot in and out is provided on the opposite side of the sole 104. An elastic narrow cloth 114 is provided on the inside of the foot cover 100 (the side in contact with the foot F: the skin side) over the entire circumference of the upper edge of the opening. When the elastic narrow fabric 114 is stretched when wearing the foot cover 100, the opening is wide open, so that it is easy to wear, and after wearing the foot cover 100, the elastic narrow fabric 114 is contracted to open. Since the portion is small, the foot cover 100 does not come off during walking. It should be noted that the stretchable narrow cloth 114 may be provided on the outside of the foot cover 100 (the side opposite to the side in contact with the foot F: 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, the inside of the foot cover 100 (the side in contact with the foot F: the skin side) is formed of a thin transparent sheet such as silicon resin to prevent the heel portion from slipping. It is also preferable to provide 116. Therefore, the heel portion 102C is provided with the elastic narrow cloth 114 on the upper side (inside) of the fabric (more specifically, the first elastic knitted fabric 120), and further on the upper side (inside) of the heel adhesive tape described later. 106 is provided, and a heel non-slip 116 is provided on the upper side (inside) of the 106. This makes it possible to improve the adhesion of the foot F to the heel and further prevent the foot cover 100 from shifting from the heel portion of the foot F. The heel non-slip 116 is not an essential configuration for the foot cover according to the present invention.

As shown in the developed view (pattern) of FIG. 4, the feature of the foot cover 100 is that the toe portion 102A, the side 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 which is a single piece of fabric having a predetermined peripheral shape, and the sole portion 104 has a predetermined peripheral shape (generally equivalent to the sole shape). The point is that it is composed of a second elastic knitted fabric 140, which is a single piece of fabric provided. That is, the side portions 102 other than the sole portion 104 are composed of the first elastic knitted fabric 120, and the sole portion 104 is composed of the second elastic knitted fabric 140. 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 brought close to each other in the arrow X (1) direction and the arrow X (2) direction in FIG. 4, respectively.
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 in contact with each other.
The upper adhesive line 108B of the side 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 in 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 contact portion is joined with one bottom adhesive tape 108.

That is, the lower adhesive wire 108A which is the (whole) peripheral edge of the second elastic knitted fabric 140 and the upper adhesive wire 108B which is a part of the peripheral edge of the second elastic knitted fabric 140 are bonded to one bottom. The foot cover 100 is formed by joining with tape 108. The bottom adhesive tape 108 may be divided into two or more.
Further, in the first elastic knitted fabric 120, the heel left side adhesive line 106A and the heel right side adhesive line 106B are brought into close contact with each other in the Y direction indicated by FIG. 4, and are brought into contact with each other with one heel adhesive tape 106. It is joined.

In this case, the heel adhesive tape 106 and the bottom adhesive tape 108 have an adhesive coated on one side thereof (the side of the fabric (first elastic knitted fabric 120 and second elastic knitted fabric 140)) and are heated. As a result, the adhesive material applied to the heel adhesive tape 106 and the bottom adhesive tape 108 is melted and the fabrics are heat-bonded and bonded. Further, the heel adhesive tape 106 and the bottom adhesive tape 108 are heat-bonded from the back side of the foot cover 100 (the side in contact with the foot F: the skin side) to bond the fabrics. However, the heel adhesive tape 106 and / or the bottom 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 bond the fabrics. In this way, the toe 102A without the seams
The foot cover 100 including the side portion 102B, the sole portion 104, and the heel portion 102C is three-dimensionally formed.

As described above, in the foot cover 100, 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. In addition, the seams that occur when the sole and heel are sewn with different fabrics like a conventional foot cover get caught in the heel and the foot cover comes off or is worn when walking or taking off the pumps. It is possible to avoid the problem of misalignment, and since there are no seams, it is extremely comfortable to wear.

Further, in the sole portion 104, on 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), a sole slip stopper formed of a thin sheet such as silicon resin is provided. Is also preferable. This makes it possible to improve the adhesion to the inner bottom of the pump and prevent the position of the foot cover 100 from shifting in the pump. It should be noted that this non-slip sole is not an essential configuration for the foot cover according to the present invention.

In the foot cover 100, the first elastic knitted fabric 120 forming the side portion 102 other than the sole portion 104 and the second elastic knitted fabric 140 forming the sole portion 104 forming the foot cover 100. And the stretchable narrow cloth 114 may be formed of the same cloth. That is, except for the heel adhesive tape 106 and the bottom adhesive tape 108, the foot cover 100 may be all made of the same elastic fabric (tricot or the like). In the foot cover 100, the stretchable narrow cloth 114 is bonded to the cloth by heating the cloth with a heat press device to melt the adhesive material applied to the stretchable narrow cloth 114 and thermally bond it to the cloth. Has been done.

Further, in the foot cover 100, a first elastic knitted fabric 120 forming a 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. May not be the same fabric, and the first elastic knitted fabric 120, the second elastic knitted fabric 140, and the elastic narrow fabric 114 may be formed not 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 are formed. Each of the ground 140 is composed of one piece of fabric, and they are joined by the bottom adhesive tape 108, and are joined by the heel adhesive tape 106 in the first elastic knitted fabric 120 to form the heel portion 102C. Has been done. For this reason, the foot cover is a problem that occurs when the sole and heel are sewn with different fabrics as in the conventional foot cover. It is possible to avoid the problem of taking off or shifting the wearing position. Further, according to the foot cover 100, there are no seams at all, so that the foot cover 100 is extremely comfortable to wear.

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, so that the foot cover does not come off or the wearing position is not displaced when walking or taking off and putting on the pumps due to the seams, and It is particularly preferable in that it is not difficult or uncomfortable to wear due to the seams.
