Description

The present invention relates to a foot cover that, when worn, is hidden inside shoes such as sneakers (casual exercise shoes) and pumps (mainly women's shoes with a wide open instep). In particular, by arranging a support member that supports (holds) the heel at the position of the heel on the sole of the foot, it is easy to walk and is comfortable to wear, and despite the fact that such a support member is arranged, the heel Regarding a foot cover that is comfortable to wear due to its good moisture permeability.

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 become stuffy, which causes discomfort.
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 opening is greatly 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 happening.

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 the opening is made smaller, 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.

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 put on or taken off. In order to prevent the foot cover from being displaced, a foot cover having a friction imparting body attached to the inner surface of the heel contact portion is disclosed.
In Practical New Design Registration No. 3165733 (Patent Document 2), if the 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 in which the portion is formed is disclosed.

Such a foot cover is similar to a sock in that it covers the foot, and the purpose of the sock is to reduce the impact on the heel part due to walking or sports, and to make the sock look taller by wearing it. A technique for providing an insole or an insole on the heel portion is disclosed in the following prior art literature.
Japanese Unexamined Patent Publication No. 2011-015927 (Patent Document 3) prevents excessive keratinization and cracking of the skin on the heel and sole, alleviates the impact on the heel of walking and sports, and further reduces the coldness of the foot. Disclose an insole that is used in direct contact with the skin of the foot for the purpose of deodorization and the like. This insole is used in socks and stockings by attaching it directly to the skin on the heel and sole. That is, by wearing the insole in a state of being in direct contact with the heel and the sole of the foot and wearing socks and stockings from above, it can be expected that moisturizing and heat retention, as well as impact mitigation and deodorizing effects are exhibited.

Japanese Patent Application Laid-Open No. 10-066606 (Patent Document 4) discloses a heel insole for socks that keeps the height high even when the shoes are taken off and has a natural appearance because the socks are worn. In this sock insole, the heel of the sock-like plate made of cushioning material such as rubber is thickened, the upper part is matched to the roundness of the heel, and the lower part is rounded to resemble the heel, and the instep part. A sandal-type sock insole that is hard to remove when worn with a rubber band attached to it. First, if you put this sock insole on your foot and put on the sock from above, the shape will be natural when viewed from the outside, and your height will be higher by the thickness of the heel.

Japanese Unexamined Patent Publication No. 10-292206 Utility Model Registration No. 3165733 Japanese Unexamined Patent Publication No. 2011-015927 Japanese Unexamined Patent Publication No. 10-066606

In order to provide a cushioning material on the heel portion of the foot cover disclosed in Patent Document 1 or Patent Document 2, it is conceivable to apply the technique disclosed in Patent Document 3 or Patent Document 4. The foot cover is not limited to such a combination, and a foot cover having a characteristic structure in the heel portion is known.
However, when the technology disclosed in Patent Document 3 is combined with the foot cover, the insole disclosed in Patent Document 3 is only used by being directly attached to the skin of the heel and the sole of the foot, and the foot skin, the insole, and the insole. Since the foot cover and the inner surface of the shoe are configured in this order, the insole itself may be displaced from the foot skin, or the insole may be displaced from the inner surface of the shoe via the foot cover, so that the holdability is not preferable. In this respect, although there is a possibility that such a deviation can be alleviated by combining the foot cover with the technique disclosed in Patent Document 4, a rubber band for fixing to the instep must be attached. It doesn't become. In any case, when the insole or insole is brought into contact with the foot skin in this way, not only is it impossible to realize the point that the sole of the foot cover is made of a thin elastic fabric, which makes the foot feel good. The discomfort caused by the stuffiness in the shoes due to the sweat generated on the (heel part) cannot be eliminated. As a result, it becomes difficult to realize a comfortable foot cover.

The present invention has been developed in view of the above-mentioned problems of the prior art, and an object of the present invention is to arrange a support member for supporting (holding) the heel at the position of the heel of the sole of the foot. It is an object of the present invention to provide a foot cover that is comfortable to wear because it is easy to walk, and that the heel portion has good moisture permeability even though such a support member is arranged.

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 toes and the sole including the heel and exposes the instep and ankle, and is made of a thin elastic material, and has a sole and side sides. It is formed by a portion, an ankle portion, and a tubular toe portion that covers the toe tip, and an opening is provided on the opposite side of the sole portion to allow the foot to be taken in and out, and above the side portion forming the opening. An elastic narrow cloth is provided on the edge, and a thin plate-shaped support member having a three-dimensional shape covering the foot is provided at the position of the foot on the sole of the foot. The foot is provided with a left and right lateral portion and a rear portion that are erected extending from the flat surface in three directions excluding the toe side, and is provided with a covering material that covers the support member and abuts on the foot skin. The bottom portion and the covering cloth are joined to each other on the toe side of the support member.

According to the foot cover of the present invention, a support member that supports (holds) the heel is arranged at the position of the heel of the sole of the foot so that it is easy to walk and is comfortable to wear, and such a support member is arranged. Despite this, it is possible to provide a comfortable foot cover due to the good breathability of the heel portion.

It is (A) the whole perspective view and (B) the perspective view seen from the back side with the heel raised about the foot cover which concerns on embodiment of this invention. It is a plan view of the foot cover of FIG. 1, (A) side view, (B) bottom view (shoe inner surface or floor surface contact side), (C) top view of support member (sole side), (D). The DD cross-sectional view shown in (C) of the support member, the view showing the deformed state of the covering fabric by the foot F in (E) and (D), and the F direction (toe direction) shown in (C) of the support member (F). ), It is a figure which shows the deformed state of the covering cloth by a foot F in (G) (F).

Hereinafter, the foot cover 100 according to the embodiment of the present invention will be described in detail with reference to the drawings. Here, there are various structures of the foot cover, and the present invention is not limited to a specific structure, but a feature described later (a support member that supports the heel portion of the sole portion 104 so as to cover the heel). Whatever the structure of the foot cover, the type of fabric that forms the foot cover, the pattern of the fabric, and the method of joining the fabric, as long as it has 120). But basically it doesn't matter. Therefore, the structure of the foot cover 100 shown below is merely an example. Here, the up-down, left-right directions in the following description mean the directions when the wearer stands up when the foot cover 100 is worn. In addition, the toe direction (toe direction) may be described as the anterior direction, and the heel direction may be described as the posterior direction.

The foot cover 100 is formed of a plurality of fabric pieces (parts), and all of the fabrics are knitted fabrics (stretchable fabrics) having elasticity. Here, the fabric forming the foot cover (excluding the support member 120 provided on the heel portion of the sole portion 104 because it is not a fabric, but the covering fabric 122 covering the support member 120 is included) is a bare heaven (bare heaven). : Flat knitted fabric knitted using yarn (covered yarn, etc.) wound with yarns of other materials (cotton, wool, etc.) around polyurethane yarn), tricot (tricot machine which is a kind of warp knitting machine) (War knitted fabric knitted in), 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 shape change after washing, and (3) soft texture and excellent fit. , (4) It is hard to wrinkle and crease, (5) It has a porous structure, so it is breathable, and (6) It has good touch and hygroscopicity when it contains cotton, which is preferable for a foot cover.

Further, the foot cover 100 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 is a sole portion 104, a side portion 106, and a heel portion 108. And the toe portion 102 that covers the toe tip (the fabric that forms the heel portion 108 from the side side portion 106 is one fabric piece (part), but is not limited to this). Further, although not limited, the foot cover 100 shown below is shared on the left and right sides (including the support member 120), and is preferable in that the left and right sides are not mistakenly worn because they are shared on the left and right sides. If the foot cover is not shared on the left and right, the left foot and the right foot may have asymmetrical shapes (as a whole), and except for the support member 120 described later (only the part of the support member 120 is left and right). It may have a symmetrical shape (asymmetrical and partially).

Further, the foot cover 100 according to the present embodiment is covered with three fabrics (a fabric forming the toe portion 102, a fabric forming the sole portion 104, and a fabric forming the heel portion 108 from the side side portion 106). It is composed of four fabrics including the fabric 122), but the joining of these fabrics is not limited. For example, the fabrics may be joined to each other by stitching, or the adhesive is melted by heating with an adhesive tape having an adhesive coated on one surface of the strip-shaped member, and the fabrics are heat-bonded to the fabrics. It does not matter if they are joined together. Here, this joining includes those by thermocompression bonding, those by heat welding, those by heat welding, and the like.

And, characteristically, a thin plate-shaped support member 120 having a three-dimensional shape covering the heel is provided at the position of the heel of the sole portion 104. The support member 120 includes a flat surface portion 130 corresponding to the bottom surface of the heel, and left and right lateral portions 128A and rear portions 128B extending from the flat surface portion 130 in three directions excluding the toe side. .. The foot cover 100 is provided with a covering material 122 that covers the support member 120 and comes into contact with the foot skin, and the sole portion 104 and the covering material 122 are joined on the toe side (front side) of the support member 120. Has been done. As will be described in detail later, the covering fabric 122 and the sole portion 104 are joined to each other on the end portion 124 side, which is the toe side (front side) of the covering fabric 122.

More specifically, the flat surface portion 130 of the support member 120 has a flat surface shape of approximately half to approximately one-third of the sole portion 104, and is erected diagonally upward from the flat surface portion 130 on the left and right sides. The portion 128A and the rear portion 128B are extended and integrated.
Here, although not limited to, the material of the support member 120 is preferably an elastomer material such as that used for shoe insoles. For example, EVA (ethylene-vinyl acetate copolymer resin), low-resilience urethane sponge, synthetic rubber and the like are preferable as such a material, and it is also preferable to provide a polyester fiber layer having an antibacterial and deodorant treatment. Further, as long as it has rigidity described later, for example, silicone rubber (Silicone Rubber) or the like may be used. The silicone rubber means a rubber-like silicone resin (synthetic resin containing silicone as a main component), and is also called a silicone resin, a silicone rubber, or a silicone rubber.

Here, the left and right side portions 128A and the rear portion 128B that are extended from the flat surface portion 130 and erected (diagonally upward) have rigidity that does not easily bend toward the flat surface portion 130 (flat surface). Even if the heel comes into contact with the support member 120 (although the heel indirectly comes into contact with the support member 120 via the covering cloth 122) even if the portion erected from the portion 130 has a waist). It is preferable to have a cushioning property that does not cause pain in the heel. In this case, the rigidity means that the left and right side ends and the heel side rear end of the covering fabric 122 are locked by the upper ends of the left and right side portions 128A and the rear end portion 128B of the supporting member 120, respectively, and the covering fabric 122 is the supporting member. Even if tension is applied to the covering fabric 122 so that it floats from 120 (even if it is slightly pulled and becomes the state shown in FIGS. 2 (D) and 2 (F) described later), the solid support member 120 is formed. It means rigidity that does not change the shape.

The foot cover 100 having such a feature will be described in detail below.
1 and 2 show the foot cover 100 according to the embodiment of the present invention. FIG. 1A is an overall perspective view of the foot cover 100, and FIG. 1B is a perspective view of the foot cover 100 as viewed from the back side with the heel raised. FIG. 2A is a side view of the foot cover 100, FIG. 2B is a bottom view of the foot cover 100 (shoe inner surface or floor contact side), and FIG. 2C is a support member. It is a top view (sole side) of 120, FIG. 2 (D) is a cross-sectional view taken along the line DD shown in FIG. 2 (C) of the support member, and FIG. 2 (E) shows the foot in FIG. 2 (D). It is a figure which shows the deformation state of the covering cloth 122 by F, and FIG. 2 (F) is the side view of the support member 120 seen from the F direction (toe direction) shown in FIG. FIG. 2 (G) is a diagram showing a deformed state of the covering fabric 122 by the foot F in FIG. 2 (F).

In addition, in FIG. 1 and FIG. 2, it is assumed that the foot cover 100 is worn (standing up) 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, it will be in a shrunk state if it is not shown in this assumption, and the shape should be understood. Is difficult, so it is assumed as described above.

However, with respect to the covering cloth 122 that covers the support member 120, the covering cloth 122 in FIGS. 2 (D) and 2 (F) shows the shape before the foot cover 100 is worn on the wearer's foot F. That is, in the support member 120, the sides in the three directions described above are erected diagonally upward, and the left and right side ends and the heel side rear end of the covering fabric 122 are respectively in a state where the wearer's weight is not applied. A large space S is created between the flat surface portion 130 of the support member 120 and the covering fabric 122 by being locked by the upper ends of the left and right side portions 128A and the upper ends of the rear portion 128B and tension is applied to the covering fabric 122. The foot cover 100 is formed as described above. Therefore, when the foot cover 100 is not worn, the weight of the wearer is not applied, so that the covering fabric 122 is not deformed and the support member 120 is not deformed as shown in FIGS. 2 (D) and 2 (F). While a large space S is generated between the flat surface portion 130 and the covering fabric 122, when the foot cover 100 is worn and stands up (when shoes are worn), the weight of the wearer is applied. As shown in FIGS. 2 (E) and 2 (G), the covering cloth 122 is deformed along the shape of the heel, and a large space S is generated between the flat surface portion 130 of the support member 120 and the covering cloth 122. It's gone. Since it is difficult to understand the difference in the space S, regarding the covering fabric 122 that covers the support member 120, the covering fabric 122 is the wearer's foot F only in FIGS. 2 (D) and 2 (F). Shows the shape of the foot cover 100 before it is worn.

As can be understood by referring to these figures, 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 cut so as not to be exposed from shoes such as sneakers when worn. The foot cover 100 is a thin elastic fabric (tricot) in which the opening, which is the opening, is cut larger so that the instep, which is the opening, is not exposed from the pumps, which is wider than the sneakers when worn. Etc.) may be formed. Here, the fact that the foot cover 100 is not exposed from the shoes or the pumps when worn includes the fact that the foot cover 100 is hidden by the shoes or the pumps and becomes invisible or difficult to see.

The foot cover 100 is formed of a toe portion 102, a sole portion 104, a side side portion 106, and a heel portion 108. An opening for putting the foot in and out is provided on the opposite side of the sole 104. The opening will be formed in the upper part of the toe part 102, the upper part of the side side part 106, and the upper part of the heel part 108. In this foot cover 100, for example, the toe portion 102, the sole portion 104, the side side portion 106, and the heel portion 108 are separately knitted (the side side portion 106 and the heel portion 108 are integrally knitted one piece of fabric). (Parts)), the side side 106 and the heel 108 and the toe 102 are sewn together and integrated, and further, these integrated toe 102, the side 106 and the heel 108 and the sole are integrated. 104 is sewn and integrated.

In the foot cover 100, an opening for putting the foot in and out on the opposite side to the sole portion 104 is formed by the toe portion 102, the side side portion 106, and the heel portion 108. The stretchable narrow cloth 112 and the stretchable narrow cloth 116 are 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 112 and the elastic narrow fabric 116 are stretched when the foot cover 100 is worn, the opening is widened so that the foot cover 100 is easy to wear, and after the foot cover 100 is worn, the foot cover 100 is stretchable. Since the narrow cloth 112 and the elastic narrow cloth 116 contract to reduce the opening, the foot cover 100 does not come off during walking. In addition, the stretchable narrow cloth 112 and the stretchable narrow cloth are on the outside of the foot cover 100 (the side opposite to the side in contact with the foot F: the side in contact with the inner surface of the shoe) over the entire circumference of the upper edge of the opening. 116 may be provided.

The stretchable narrow cloth 112 and the stretchable narrow cloth 116 may be provided not on the entire circumference of the upper edge of the opening but on a part of the upper edge, and may be provided intermittently rather than continuously. It may be provided. In any case, the stretchable narrow cloth 112 and the stretchable narrow cloth 116 make it easy to put on the foot cover 100, and the foot cover 100 is less likely to come off or shift due to an operation such as walking.

Here, as an example of the stretchable narrow cloth 112 and the stretchable narrow cloth 116, a nylon tape can be mentioned. It is also preferable that the stretchable narrow cloth 112 and the stretchable narrow cloth 116 are made of the same cloth as the stretchable cloth constituting (at least a part of) the foot cover 100.
Further, on the upper edge of the heel portion 108 of the foot cover 100, on the inside of the foot cover 100 (the side in contact with the foot F: the skin side), the heel portion is non-slip formed of a thin transparent sheet such as silicone resin. It is also preferable to provide 118. As a result, it is possible to improve the adhesion of the foot F to the heel and further prevent the foot cover 100 from being displaced from the heel portion of the foot F. The heel non-slip 118 is not an essential configuration for the foot cover according to the present invention.

In this foot cover 100, at the position of the heel of the sole 104, the flat surface 130 corresponding to the shape of the bottom surface of the heel (the shape of the heel, not the ankle side, but the sole side), the left and right side portions 128A, and the rear portion 128B. A three-dimensional support member 120 that covers the heel is provided. It is preferable to provide a non-slip on the contact side of the sole 104 of the flat surface portion 130 as in the heel non-slip 118 described above, because the relative positions of the support member 120 and the sole 104 do not shift.

The shape of the support member 120 and its function (action and effect) will be described with reference to FIGS. 2 (A) to 2 (G). This function is based on the shape in which the left and right side portions 128A and the rear portion 128B of the support member 120 stand upright from the flat surface portion 130, and the covering fabric 122 is in a state of floating from the support member 120. It is based on the shape of the foot cover 100 formed by applying tension to the covering cloth 122 so as to be such that the covering cloth 122 is locked to the upper ends of the left and right side portions 128A and the upper ends of the rear portion 128B.

First, the structure of the foot cover 100 for bringing the support member 120 into contact with the sole portion 104 of the foot cover 100 and fixing the position thereof will be described.
As shown in FIGS. 1 (A) and 1 (B) and FIGS. 2 (A) and 2 (B), the support member 120 is a surface (sole side) of the sole portion 104 side (sole side) of the covering fabric 122. The upper end of the left and right side portions 128A and the upper end of the rear portion 128B are provided so as to abut against the surface on the opposite side of the sole contact surface), and the support member 120 is placed in the middle on the upper and lower opposite sides of the sole portion 104. A covering cloth 122 that covers the support member 120 and comes into contact with the foot skin is provided. That is, the support member 120 is sandwiched between the sole portion 104 and the covering cloth 122 in this way. Then, the sole portion 104 and the covering fabric 122 are joined by the joint portion 126 on the toe side of the support member 120. It should be noted that the left and right sides of the support member 120 are not joined by such a joint portion 126, and the left and right sides are tensioned by the covering fabric 122 to apply tension to the sole portion 104, the side side portions 106, and the covering fabric. The point is that the 122 is joined (sewn) to form a large space S between the flat surface portion 130 of the support member 120 and the covering fabric 122. Here, as an example of the joint portion 126 on the toe side of the support member 120, the adhesive is melted by heating using a double-sided adhesive tape in which the adhesive is applied to both sides of the thin strip-shaped member, and the fabric is heat-bonded. It does not matter if the fabrics are joined to each other. Here, this joining includes those by suturing, thermocompression bonding, heat welding, heat welding and the like. When such a double-sided adhesive tape is adopted, the sole portion 104 and the covering fabric 122 are supported by the toe side (sometimes referred to as the toe side) of the support member 120, although they are joined by the double-sided adhesive tape. The left and right sides of the member 120 are not joined by the double-sided adhesive tape. When double-sided adhesive tape is used as the joint 126, there is less discomfort as the sole feels (because the seams do not hit compared to sutures), and when a thin double-sided adhesive tape is adopted, the sole feels discomfort. Is even less.

In this way, the support member 120 is sandwiched between the sole portion 104 and the covering fabric 122, and the sole portion 104 and the covering fabric 122 are formed on the toe side (the toe side, not the left and right sides) of the support member 120. On the left and right sides, the covering fabric 122 is joined (sewn) together with the sole portion 104 and the side side portions 106, so that the support member 120 is brought into contact with the sole portion 104 of the foot cover 100 so as not to be displaced. The position can be fixed.

Further, in this case, as shown in FIGS. 2 (D) and 2 (F), before the foot cover 100 is worn on the wearer's foot F, the left and right side ends and the heel side rear end of the covering fabric 122 Are locked by the upper ends of the left and right side portions 128A and the upper ends of the rear portions 128B, respectively, and tension is applied to the covering fabric 122, so that a large space S is provided between the flat surface portion 130 of the support member 120 and the covering fabric 122. Is occurring. That is, when the foot cover 100 is not worn, the weight of the wearer is not applied, so that the covering fabric 122 is not deformed and the flat surface of the support member 120 as shown in FIGS. 2 (D) and 2 (F). A large space S is formed between the portion 130 and the covering fabric 122.

On the other hand, as shown in FIGS. 2 (E) and 2 (G), when the foot cover 100 is worn and stands up (when shoes are worn), the weight of the wearer is applied and the covering fabric 122 is applied. Is deformed along the shape of the heel, and the large space S existing between the flat surface portion 130 of the support member 120 and the covering cloth 122 is no longer generated. However, even at this time, as shown in FIGS. 2 (E) and 2 (G), although the volume is smaller than the space S, the space S (1) is on the heel side and the space S (2) is on the toe side. ) Has occurred. Here, the space S (2) on the toe side is generated by the arch shape of the sole of the foot (the shape in which the bottom surface of the sole is recessed), which is present in many people. Further, the space S (1) on the heel side is generated by making the rise of the support member 120 from the flat surface portion 130 to the rear portion 128B steeper than the curvature of the heel (and the rigidity of the support member 120). Can be done.

Effects when the wearer wears the foot cover 100 having the above structure on the foot F, or when the wearer wears the foot cover 100 on the foot F and further wears shoes (A) to ( The effect (E) when the wearer does not wear the foot cover 100 and the foot cover 100 on the foot F will be described.
(A) The volume of the covering cloth 122 is larger than that of the large space S existing between the flat surface portion 130 of the support member 120 and the covering cloth 122 due to the weight of the wearer being applied and the covering cloth 122 being deformed along the shape of the heel. A space S (1) is generated on the heel side and a space S (2) is generated on the toe side of a small object. Since an air layer can be provided even when worn in this way, the moisture permeability (breathability) of the heel portion is preferable and the wearing comfort is good.
(B) Since the heel is held by the three-dimensional shape of the support member 120, the holdability is high even when walking, and the foot cover 100 does not shift from the foot (particularly the heel), so that it is comfortable to wear.
(C) By providing the cushioning property of the support member 120, the support member 120 provided at the heel position with a size of about half to about one-third of the heel side of the sole portion 104 is a preferable cushion when walking. Can express sex.

(D) The support member 120 does not come into direct contact with the bare skin of the sole of the foot, but comes into contact with the covering cloth 122 through the covering cloth 122.
