Description

In the present invention, the opening is formed on the upper surface,
The present invention relates to a foot cover including a front bag portion positioned in front of the opening, a sole portion positioned below the opening, and a heel portion positioned behind the opening.

BACKGROUND ART As a kind of sock, a foot cover is known that, even when worn while wearing shoes such as sneakers or pumps, most of it is hidden inside the shoe so that it looks as if the shoe is worn barefoot.
Such a foot cover has a wider opening than other ordinary socks, so there is a problem that the heel part slips and comes off during walking.
As a foot cover for solving such problems, a foot cover has been proposed in which a non-slip portion made of silicone resin is attached to the inner surface of the heel portion (see, for example, Patent Document 1).

JP 2014-43662 A

In the foot cover described in Patent Document 1, since the anti-slip portion is attached to the inner surface of the heel portion, unevenness is formed on the inner surface of the heel portion, resulting in a problem of poor wearing comfort. In addition, such a non-slip portion tends to come off due to washing, long-term use, and the like, and there have been cases where the effect of preventing slippage of the heel portion cannot be maintained.

In view of this situation, the main object of the present invention is to provide a foot cover that can prevent the heel from slipping without impairing the feeling of wearing.

The first characteristic configuration of the present invention is that the opening is formed on the upper surface,
A foot cover comprising a front bag portion positioned in front of the opening, a sole portion positioned below the opening, and a heel portion positioned behind the opening,
In the front bag portion, a low stretchable portion having lower stretchability in the front-rear direction than the sole portion is provided at least on the front side of both ends of the front edge of the opening ,
The front bag part is composed of a ring part knitted by circular knitting all around and a toe part knitted from the lower half circumference part of the ring part by reciprocating knitting so as to wrap the toe and sewn to the upper half circumference part of the ring part. configured,
A high-elasticity belt-shaped portion having higher elasticity in the circumferential direction than the sole portion is knitted in the belt-shaped portion extending all around the front edge of the opening,
The low-stretchable portion is knitted in the ring portion at a position along the extending direction of both side edges of the opening on the front side of the high-elasticity belt-shaped portion,
The point is that the low elastic portion is not provided in the sole portion .

According to this configuration, since the low stretchable portion is provided in the front bag portion located in front of the opening, the low stretchable portion stretches in the front-rear direction when the entire body stretches in the front-rear direction when worn. is suppressed more than the sole. Then, a tensile force that pulls both ends of the front edge of the collar forward from the low stretchable portion is generated, and the tensile force is transmitted to both ends of the rear edge of the collar through the side edges of the collar. will be
In this way, when a tensile force that pulls forward is applied to both ends of the rear edge of the shoe opening, the rear edge of the shoe opening satisfactorily catches the depression above the wearer's heel (the depression of the Achilles tendon), that state is maintained. Therefore, it is possible to suitably prevent the heel from slipping during walking.
Therefore, according to the present invention, it is possible to provide a foot cover that can prevent the heel from slipping without impairing the feeling of wearing.
Furthermore, according to this configuration, the entire periphery passing through the front edge of the opening is configured as the high-elasticity band-like portion, so that the high-elasticity band-like portion is contracted in the circumferential direction when the wearer wears the shoe, resulting in the wearer's arch. It can be made to adhere to nearby dents.
Furthermore, according to this configuration, since the rear side of the front bag portion is configured as the ring portion knitted by circular knitting all around, in the ring portion, the low stretchable portion is positioned at the front edge of the opening. It can be easily knitted on the front side of both ends. That is, the low stretchable portions are positioned immediately before the front ends of the side edges of the opening (in other words, both ends of the front edge of the opening). As a result, when worn, a tensile force can be favorably applied to the front ends of both side edges of the opening located immediately behind the low stretchable portion, and both ends of the rear edge of the opening can be applied. By increasing the tensile force transmitted to the heel, slippage of the heel can be further prevented.

A second characteristic configuration of the present invention is that the low-stretchable portion is configured as both ends of a low-stretchable belt-like portion along at least the front edge of the opening in the front bag portion.

According to this configuration, since the low-stretchable portion is configured as both ends of the low-stretchable belt-like portion along at least the front edge of the opening in the front bag portion, the entirety stretches in the front-rear direction when worn. In doing so, a tensile force can be created that pulls the entire front edge of the collar forward. As a result, the instep of the wearer can be exposed to a greater extent from the opening. Further, the forward pulling force transmitted to both ends of the rear edge of the collar is increased to further prevent the heel from slipping.

A third characteristic configuration of the present invention is that the low-stretch band-like portion is provided adjacent to the front of the high-elastic band-like portion.

According to this configuration, when worn , a tensile force that pulls forward from the low-stretchable band-like portion to the front ends of both side edges of the opening is suitably transmitted in the substantially upper half circumference portion of the high-elasticity band-like portion. On the other hand, it is possible to prevent the sole from slipping forward due to the tensile force in the substantially upper half circumference of the highly elastic strip.

A fourth characteristic configuration of the present invention is that the rear edge of the opening is formed as a folded portion formed by folding the upper end of the heel portion.

According to this configuration, by forming the rear edge of the opening as the folded portion, the rear edge of the opening can be easily caught in the depression above the heel of the wearer, thereby preventing the heel from slipping. This can be further prevented.

According to a fifth characteristic configuration of the present invention, both side edges of the opening are configured as both side ends of the sole portion knitted by reciprocating knitting.

According to this configuration, the both side edges of the opening are knitted by reciprocating knitting by utilizing the fact that the elasticity in the wale direction (the longitudinal direction of the knitted fabric) is reduced at both side edges of the reciprocating knitting. By constructing it as both side ends of the sole, the tensile force transmitted from the low-stretch belt-like portion to the front ends of the both side edges of the shoe opening is transmitted through the both side edges of the shoe opening with low elasticity. It can be ensured that both ends of the rear edge of the collar can be acted upon.

An embodiment of the present invention will be described based on the drawings.
The foot cover 20 shown in FIGS. 1 and 2 includes a front bag portion 1 positioned in front of the opening 10 formed on the upper surface thereof, a sole portion 6 positioned below the opening 10, and a heel portion 7 positioned behind the opening 10. - 特許庁Incidentally, such a foot cover 20 can be integrally knitted by a known fully automatic circular knitting machine.

The foot cover 20 is worn by inserting the foot into the opening 10 while being stretched in the longitudinal direction, and most of the wearer's ankles and insteps are exposed from the opening 10 when worn. Therefore, if such a foot cover 20 is worn when wearing shoes such as sneakers or pumps, most of the foot cover 20 is hidden inside the shoes and cannot be seen, and it looks as if the shoes are worn barefoot.

The front bag portion 1 positioned in front of the opening 10 is knitted by a ring portion 3 which is knitted by circular knitting around the whole circumference, and is knitted by reciprocating knitting so as to wrap the toe from the lower half circumference of the ring portion 3 and the top of the ring portion 3. It is composed of a toe portion 2 sewn with a sewn portion 12 by linking or the like to the semicircumferential portion. Both side surfaces of the toe portion 2 are provided with gore lines 13 for forming the toe portion 2 so as to swell three-dimensionally. In the present embodiment, the front bag portion 1 is knitted by normal knitting except for the low-stretch band-like portion 4 and the high-elasticity band-like portion 5, which will be described later.

The sole portion 6 located below the opening 10 is knitted by reciprocating knitting from the lower half circumference of the ring portion 3 along the sole and side of the wearer's foot. The heel portion 7 located behind the opening 10 is knitted by reciprocating knitting so as to wrap the heel of the wearer from behind the sole portion 6. - 特許庁On both side surfaces of the heel portion 7, gore lines 14 are provided for forming the heel portion 7 to expand in three dimensions. The sole portion 6 and the heel portion 7 are knitted by normal knitting except for the folded portion 8 which will be described later.

The opening 10 consists of a front edge 10f that is the rear end of the upper half circumference of the ring portion 3, both side edges 10s that are the side ends of the sole portion 6, and the upper end of the heel portion 7. It is formed as an opening surrounded by the rear edge 10r.

The basic structure of the foot cover 20 has been described above, and the foot cover 20 of this embodiment has a characteristic structure for preventing the heel portion 7 from slipping without impairing the feeling of wearing. The characteristic configuration will be explained below.

A low-stretch band-like portion 4 having lower stretchability in the front-rear direction than the sole portion 6 is provided in a band-like portion along at least the front edge portion 10f of the opening 10 in the front bag portion 1 . Specifically, the low-stretch band-like portion 4 is a band-like portion extending left and right from the upper central portion of the ring portion 3 that constitutes the rear side of the front bag portion 1. As shown in FIG. The front edge 10f of the opening 10 is knitted slightly below both ends.
Both ends of the low-stretch belt-shaped portion 4 are provided at least on the front side of both ends of the front edge portion 10f of the opening 10 in the front bag portion 1, and are more stretchable in the front-rear direction than the sole portion. It becomes the low low expansion-contraction part 4a.

As described above, the low-stretch band portion 4 having lower stretchability than the sole portion 6 in the front-rear direction of the foot cover 20 corresponding to the wale direction (longitudinal direction) of the knitted fabric can be constructed by various methods.
For example, while the sole portion 6 is knitted by normal knitting, as shown in FIG. 3 or 4, the low-stretch belt-like portion 4 is knitted by tuck knitting having a property of being difficult to stretch in the wale direction. Therefore, the stretchability of the low-stretch belt-like portion 4 can be made lower than that of the sole portion 6. - 特許庁
Specifically, in the tuck knitting shown in FIG. 3, a tuck portion T1 skipped by one stitch in the wale direction W is formed on the same wale, and the wale on which the tuck portion T is formed is woven in one stitch in the course direction C (horizontal direction). It is configured to appear every other time. The skipped tuck portion T1 is formed by pulling out the knitting yarn through two stitches at the same time when the stitches are formed by the supplied yarn Y in knitting.
The tuck knitting shown in FIG. 4 is configured by arranging tuck portions T2 skipping two stitches in the wale direction W in a staggered manner. The tuck portion T2 skipping two stitches is formed by pulling out the knitting yarn Y through three stitches at the same time when the stitches are formed by the supplied yarn Y in knitting.

In addition, such a low-elasticity, low-elasticity belt-like portion 4 is knitted, for example, by a knitted knitting or the like in which a high-elasticity or non-elasticity attachment yarn or a heat-fusible yarn that is hardened by a subsequent heat treatment is attached to the yarn supply. By doing so, the elasticity of the low-stretch band-shaped portion 4 can also be reduced. In addition, the low-elasticity belt-like portion 4 can be knitted by a knitting method other than the above, such as pique knitting or rubber knitting. In addition, the low-stretch belt-like portion 4 may be configured as a printed portion formed by fixing a vinyl chloride or silicon laminate at a high temperature, or may be formed by sewing or adhering another fabric to the knitted fabric of the low-stretch belt-like portion 4. The stretchability of the low-stretchable belt-like portion 4 can also be reduced by using a multi-layered structure.

Since such a low-stretchable band-shaped portion 4 is provided in the ring portion 3 of the front bag portion 1, when the whole stretches in the front-rear direction when worn, the low-stretchable band-shaped portion 4 does not stretch in the front-rear direction. It will be suppressed more than the sole part 6 . Then, a tensile force that pulls the front edge 10f of the opening 10 forward is generated from the low-elasticity belt-like portion 4, particularly the low-elasticity portion 4a. is transmitted to both ends of the rear edge portion 10r of the opening 10 through.

In this way, when a tensile force that pulls the rear edge 10r of the opening 10 forward acts on both ends of the opening 10, the rear edge 10r of the opening 10 is satisfactorily caught in the depression above the heel of the wearer. is maintained. As a result, it is possible to preferably prevent the heel portion 7 from slipping during walking.

Furthermore, in the ring portion 3 knitted by circular knitting around the entire circumference of the front bag portion 1, the low stretchable portions 4a, which are the portions at both ends of the low stretchable belt-shaped portion 4, are particularly shown in FIG. They are provided at front side portions of both ends of the front edge portion 10f, which are connecting portions to the side edge portions 10s. As a result, when the shoe is worn, a favorable tensile force acts on the front end portions of the side edges 10s of the opening 10 positioned immediately behind the low stretchable portion 4a. Therefore, the tensile force transmitted to both ends of the rear edge portion 10r of the opening 10 is increased, and the displacement of the heel portion 7 is further prevented.

Furthermore, since the low-stretchable belt-shaped portion 4 is formed as a belt-shaped portion along the front edge 10f of the opening 10, a tensile force that pulls the entire front edge 10f of the opening 10 forward is generated when worn. As a result, the instep of the wearer is exposed to a greater extent from the opening.

A rear edge portion 10r of the opening 10 is formed as a folded portion 8 formed by folding the upper end portion of the heel portion 7 twice and sewing it. Further, a rubber thread is inserted in the weft direction in the folded portion 8 . That is, the folded portion 8 is thicker than the other portions and configured as a portion having high elasticity in the left-right direction. As a result, the rear edge 10r of the opening 10 configured as the folded portion 8 can be well caught in the recess above the heel of the wearer, further preventing the heel portion 7 from slipping. become.

Since the elasticity in the wale direction is reduced at both side ends of the reciprocating knitting, the side edges 10s of the opening 10, which are formed as both side ends of the sole portion 6 knitted by reciprocating knitting, are not suitable for the foot. The stretchability in the wale direction is lower than that on the central portion side of the bottom portion 6 . As a result, the tensile force transmitted from the low-stretch belt-shaped portion 4 to the front end of the side edges 10s of the opening 10 is reliably transmitted through the side edges 10s of the opening 10 having low elasticity. As a result, the heel portion 7 is further prevented from slipping.

A high-elasticity belt-like portion 5 having higher elasticity in the circumferential direction than the sole portion 6 is knitted in the belt-like portion extending all around through the front edge portion 10f of the opening 10. - 特許庁In addition, the low-stretch band-shaped portion 4 is provided adjacently in front of the substantially upper half circumference of the high-elasticity band-shaped portion 5, and the front edge 10f of the opening 10 is provided behind the substantially upper half-circumference of the high-elasticity band-shaped portion 5. are placed adjacent to each other.

Such a highly elastic band-shaped portion 5 shrinks in the circumferential direction when worn, and adheres closely to the depression near the arch of the wearer's foot. This prevents the sole portion 6 from shifting in the front-rear direction. On the other hand, in the substantially upper half circumference of the highly elastic strip 5, the wearer's instep has almost no depression, so that moderate forward movement is permitted. As a result, the repulsive force of the low-stretch belt-shaped portion 4 can be suitably transmitted to the front end portion of the side edge portions 10s of the opening 10 as a tensile force that pulls the front end portion forward. In the present embodiment, the high-elasticity belt-like portion 5 is knitted by ordinary rubber knitting, but it may be knitted with, for example, a rubber thread so as to increase the elasticity.
