JP 2014-43662 A

The heel portion of the foot cover is a portion that bulges rearward along the shape of the heel of the wearer, and is configured as a relatively flexible knitted fabric to ensure a suitable wearing feeling. Therefore, in such a flexible heel part, it becomes difficult to generate a force for pressing the high frictional anti-slip part provided on the inner surface of the substantially central part against the wearer's heel surface, and the foot cover heel part is prevented from slipping. In some cases, the effect could not be fully exhibited.
In addition, when a high-friction anti-slip portion having a thickness is provided on the inner surface of the substantially central portion of the heel portion of the foot cover, a convex portion is formed on the outer surface of the heel portion corresponding to the high-friction anti-slip portion. The Then, the convex part formed in the outer surface of the heel part of the foot cover comes into contact with the inner surface of the heel part of the shoe, and a relatively large frictional force is generated between them. Then, such a frictional force may cause a problem that the heel portion of the foot cover is displaced from the wearer's heel inside the shoe.

In view of this situation, the main problem of the present invention is to provide a foot cover capable of suitably preventing the shift at the buttocks and the toes.

According to the first characteristic configuration of the present invention, the mouth is formed on the upper surface,
A foot cover including a front bag portion located in front of the mouth, a sole portion located below the mouth, and a heel portion located behind the mouth;
An anti-slip portion is provided at a rear edge portion of the mouth in the heel portion.

According to this configuration, when the mouth is stretched in the front-rear direction at the time of wearing, the side edge of the mouth is stretched in the front-rear direction, and the tensile force of the side edge is a depression above the wearer's heel. It acts as a pulling force toward the front with respect to the rear edge of the mouth that gets caught in (the depression of the Achilles tendon).
And the slip prevention part is provided in the back edge part of the wear mouth. Thereby, the said anti-slip | skid part will be suitably pressed on the surface of a wearer's heel upper part with the tensile force toward the front which acts with respect to a back edge part from the side edge part of a wear mouth. Therefore, a favorable frictional force is generated between the anti-slip portion provided on the inner surface of the rear edge portion of the mouth and the surface of the wearer's heel, and as a result, the displacement of the heel of the foot cover is suitably prevented. Can do.
In addition, since the non-slip portion is provided on the inner surface of the rear edge of the mouth that is caught in the depression above the wearer's heel, a convex portion due to the thickness of the anti-slip portion is formed on the outer surface. Even so, the convex portion is suppressed from coming into contact with the inner surface of the heel of the shoe. Therefore, it can prevent that a frictional force arises between the convex part and the inner surface of a shoe, and can prevent suitably that the heel part of a foot cover removes from a wearer's heel inside a shoe.
Therefore, according to the present invention, it is possible to provide a foot cover capable of suitably preventing the shift of the collar portion.

The second characteristic configuration of the present invention is that a high-friction anti-slip portion made of a high-friction material is provided as an anti-slip portion on the inner surface of the rear edge of the wear mouth.

According to this configuration, when the mouth is stretched in the front-rear direction at the time of wearing, the side edge of the mouth is stretched in the front-rear direction, and the tensile force of the side edge is a depression above the wearer's heel. It acts as a pulling force toward the front with respect to the rear edge of the mouth that gets caught in (the depression of the Achilles tendon).
And the high friction material anti-slip | skid part made from a high friction material is provided in the inner surface of the back edge part of the wear mouth. Accordingly, the high frictional anti-slip portion is suitably pressed against the surface above the wearer's heel by the forward tensile force acting on the rear edge from the side edge of the wearer's mouth. Become. Therefore, a good frictional force is generated between the high-friction anti-slip part provided on the inner surface of the rear edge of the mouth and the surface of the upper part of the wearer's heel. Can be prevented.
In addition, since the high-friction anti-slip part is provided on the inner surface of the rear edge of the mouth that hooks into the dent above the wearer's heel, the outer surface has a protrusion due to the thickness of the high-friction anti-slip part. Even if it is a case where a part is formed, it is suppressed that the convex part contacts the heel part inner surface of shoes. Therefore, it can prevent that a frictional force arises between the convex part and the inner surface of a shoe, and can prevent suitably that the heel part of a foot cover removes from a wearer's heel inside a shoe.
Therefore, according to the present invention, it is possible to provide a foot cover capable of suitably preventing the shift of the collar portion.

3rd characteristic structure of this invention is comprised as a folding | returning part which the back edge part of the said mouth folds up the upper edge part of the said collar part,
The high-friction anti-slip portion is provided on the inner surface of the folded portion.

According to this configuration, by configuring the rear edge of the mouth as the folded portion, the hook of the rear edge of the mouth to the dent above the wearer's heel is good, and the shift of the heel is This can be further prevented.
Further, such a folded portion is formed by folding the upper end portion of the heel portion, so that the stretchability is lower than the other knitted fabric of the heel portion. Therefore, when the wearer's mouth spreads around the wearer's ankle, a relatively large tension is generated in the folded portion configured as the rear edge of the wearer, and the high friction provided on the inner surface of the folded portion by the large tension. The anti-slip portion is pressed against the surface above the wearer's heel with a relatively large force. Therefore, it is possible to increase the frictional force of the high-friction non-slip portion with respect to the surface of the wearer's upper portion of the wearer, and to further prevent the shift of the foot portion of the foot cover.
Further, even when a high-friction anti-slip part having a thickness is provided on the inner surface of the folded part, the outer surface of the folded part is absorbed to some extent by the thickness of the folded part. Then, it becomes difficult to form the convex part resulting from the thickness of a high-friction anti-slip part. Therefore, the shift | offset | difference of the heel part of the foot cover in the inside of the shoes resulting from the convex part can be suppressed more favorably.

According to a fourth feature of the present invention, the upper belt-like region along the rear edge of the mouth has a high elasticity that is higher in elasticity than the region below the upper belt-like region of the heel portion as the anti-slip portion.踵 There is an upper end strip.

According to this configuration, when the mouth stretches in the front-rear direction when worn, when the mouth spreads around the wearer's ankle, the highly elastic heel upper end belt-like portion provided in the upper belt-like region of the buttock is worn by the mouth. By stretching along the edge of the shoe, a relatively large tension is generated in the high-elastic heel upper end belt-like portion in the direction of pulling the rear end portions of the both side edge portions of the mouth toward the rear. In this way, tension is generated in the upper elastic band-like belt, so that the pulling force toward the front is exerted on both ends of the rear edge of the wearer hooked on the dent above the wearer's heel (dent of the Achilles tendon). As a result, the shift of the heel portion of the foot cover can be suitably prevented.
Further, the tension generated in the upper elastic belt upper end belt-like portion is transmitted forward through both side edge portions of the shoe mouth, so that the pulling force toward the rear side is exerted on both ends of the front edge portion of the mouth mouth. Since this acts, for example, even when the wear mouth is made large forward, it is possible to suitably prevent the toe portion of the foot cover from shifting.
In addition, since the high elasticity heel upper end band-like part becomes higher in elasticity toward both side edge parts of the mouth at the front, the lower side of the heel part than the high elastic heel upper end band-like part fits the wearer's heel It is possible to more suitably prevent the shift of the heel portion of the foot cover by making the shape having a bulging shape.
Therefore, according to the present invention, it is possible to provide a foot cover that can suitably prevent displacement at the heel part or the toe part.

According to a fifth characteristic configuration of the present invention, a rear edge portion of the mouth is configured as a folded portion formed by folding an upper end portion of the heel portion,
The high elastic scissor upper end belt-like portion is provided adjacent to the lower edge of the folded portion.

According to this configuration, by configuring the rear edge of the mouth as the folded portion, the hook of the rear edge of the mouth to the dent above the wearer's heel is good, and the shift of the heel is This can be further prevented.
Further, such a folded portion is formed by folding the upper end portion of the heel portion, so that the stretchability is lower than the other knitted fabric of the heel portion. Therefore, when the wearer's mouth spreads around the wearer's ankle, the folded back part configured as the rear edge of the wearer's mouth extends along the edge of the wearer's mouth, so that the rear ends of both side edges of the wearer's mouth A relatively large tension is generated in the folded portion in the direction of pulling the portion backward.
And by combining the tension generated in the folded portion and the tension generated in the upper elastic band upper strip adjacent to the lower side, both ends of the rear edge of the shoe mouth and both ends of the front edge of the shoe mouth, By increasing the pulling force toward the inside, it is possible to more suitably prevent the shift of the heel portion and the toe portion of the foot cover.

A sixth characteristic configuration of the present invention is that a high-friction anti-slip portion made of a high-friction material is provided as the anti-slip portion on at least the inner surface of the high-elastic heel upper end belt-like portion of the heel portion. .

According to this configuration, at least the high-friction anti-slip portion provided on the inner surface of the high-elastic heel upper-end belt-like portion provided in the upper belt-like region of the heel portion is worn by the wearer with a relatively large pulling force. It will be pressed against the surface above the heel. Therefore, it is possible to increase the frictional force of the high-friction non-slip portion with respect to the surface of the wearer's upper portion of the wearer, and to further prevent the shift of the foot portion of the foot cover.

A seventh characteristic configuration of the present invention is that a plurality of side gore lines extending from a plurality of positions on both side edge portions of the mouth to the sole are provided.

According to this configuration, since the plurality of side gore lines extending from the plurality of portions on both side edge portions of the mouth toward the sole of the lower side are provided, the sole portion has sufficient swelling. Become. Therefore, even if the tension generated by the anti-slip portion such as the high elastic band upper end belt-like portion is transmitted to the both side edges of the shoe mouth to prevent slippage and removal, it is tight for the wearer. Giving a feeling of wearing can be suppressed.

In an eighth characteristic configuration of the present invention, a highly stretchable front belt-like portion having higher stretchability in the front-rear direction than the other regions in the sole portion is provided in a belt-like region extending all around the front edge of the footwear. It is in the point.

According to this configuration, the front edge of the shoe mouth is provided with a highly stretchable front belt-like portion having high stretchability in the front-rear direction in a belt-like region extending around the entire circumference. In the form in which the width of the lower half periphery of the highly stretchable front belt-like portion positioned is flexibly changed, the front and rear direction can be flexibly expanded and contracted. In this way, even when the tension generated in the anti-slip portion such as the high elastic band upper end belt-like portion is transmitted to the side edge portions of the mouth in order to prevent the slippage and removal, On the other hand, giving a tight wearing feeling can be suppressed. In addition, the front bag portion along the wearer's instep as the lower half periphery of the highly stretchable front belt-shaped portion extends in the front-rear direction and the lower surface portion of the front bag portion is displaced forward with respect to the sole. Since the upper surface portion of the body is displaced toward the rear mouth, it is possible to suppress the front bag portion from being removed from the wearer's toe.

The ninth feature of the present invention is that the belt-like region between the side edges of the footwear extending in the circumferential direction in the sole portion is highly stretchable with higher elasticity in the front-rear direction than other regions in the sole portion. The sole band-shaped part is provided.

According to this configuration, the sole portion is provided with a highly stretchable soleband portion having high stretchability in the front-rear direction in a belt-like region that crosses the sole portion, so that the width of the highly stretchable soleband portion changes flexibly. In this form, the sole portion excluding both side edge portions of the wearer can be flexibly expanded and contracted in the front-rear direction. This prevents the wearer from wearing tightly even when the tension generated by the high-elastic heel upper end belt-like portion is transmitted to both side edge portions of the shoe mouth to prevent slippage and removal. Giving can be suppressed.

According to a tenth characteristic configuration of the present invention, in the front bag portion, at least a portion on the front side of both end portions of the front edge portion of the footwear is provided with a low stretch portion having lower stretchability in the front-rear direction than the sole portion. It is in the point.

According to this configuration, since the low stretchable part is provided in the front bag part located in front of the mouth, when the whole stretches in the front-rear direction when worn, the stretch in the front-rear direction at the low stretchable part is achieved. Is suppressed more than the sole. As a result, a pulling force is generated from the low expansion and contraction portion toward the front end portions of the front edge of the shoe mouth, and the pulling force is transmitted rearward through the side edge portion of the wear mouth.
When the pulling force that pulls forward acts on both ends of the rear edge of the mouth in this way, the rear edge of the mouth is satisfactorily hooked into the depression above the wearer's heel and the state is maintained. . Furthermore, the anti-slip portion provided on the inner surface of the rear edge portion can be pressed against the surface above the wearer's heel with a large force by the tensile force acting on the rear edge portion of the wearer's mouth.
In addition, when the anti-slip portion is a high-elastic heel upper end belt-like portion, the tensile force generated by the front low-elasticity portion and the pulling force generated by the rear high-elastic heel upper end belt-like portion are combined, thereby By increasing the pulling force toward the inside of both ends of the rear edge and both ends of the front edge of the footwear, it is possible to more suitably prevent the shift of the buttocks and toes of the foot cover.
By these things, the shift | offset | difference of the buttocks and toe part of a foot cover can be prevented still more favorably.

In an eleventh characteristic configuration of the present invention, the front bag portion is knitted so as to wrap a toe by reciprocating knitting from a ring portion knitted by full-circle knitting and a lower half circumference portion of the ring portion, and an upper half circumference of the ring portion It consists of a toe part stitched to the part,
The low expansion / contraction part is knitted to the ring part.

According to this configuration, since the rear side of the front bag portion is configured as the ring portion knitted by circular knitting on the entire circumference, the ring portion has a low stretchable portion that is less stretchable in the front-rear direction than the sole portion. Can be easily knitted to the front part of both ends of the front edge of the wearer. That is, the low expansion and contraction portion is positioned immediately before the front end portions of the both side edge portions of the wear mouth (in other words, both end portions of the front edge portion of the wear mouth). Then, at the time of wearing, it is possible to satisfactorily apply a tensile force to the front end portions of both side edge portions of the wear mouth located immediately after the low stretchable portion, and both ends of the rear edge portion of the wear mouth. The tensile force transmitted to the part can be increased.
In addition, when the anti-slip part is a high-friction anti-slip part, the pressing force of the high-friction anti-slip part provided on the inner surface of the rear edge with respect to the upper surface of the wearer's heel is increased, and the foot It is possible to prevent the shift of the collar portion of the cover even better.

A twelfth characteristic configuration of the present invention is that both side edge portions of the shoe mouth are configured as both side end portions of the sole portion knitted by reciprocating knitting.

According to this configuration, the both side edge portions of the knitting mouth are knitted by the reciprocating knitting using the decrease in the stretchability in the wale direction (longitudinal direction of the knitted fabric) at the both ends of the reciprocating knitting. By constructing it as the two side ends of the sole, the pulling force transmitted from the anti-slip part provided at the rear edge of the shoe mouth to the rear edge of the both sides of the shoe mouth is expanded and contracted. It can be made to act on the front side reliably through the both side edges of the mouth with low performance. Therefore, the pulling force toward the both side edges of the inner mouth is surely applied to both ends of the rear edge of the mouth and both ends of the front edge of the mouth, so that the heel portion of the foot cover And the shift | offset | difference of a toe part can be prevented more suitably.

[First Embodiment]
1st Embodiment of the foot cover which concerns on this invention is described based on FIG.1, FIG.2 and FIG.3.
As shown in FIGS. 1 and 2, the foot cover 20 of the present embodiment has a mouth 10 formed on the upper surface, a front bag portion 1 positioned in front of the mouth 10, and a lower portion of the mouth 10. The sole portion 6 is positioned, and the heel portion 7 is located behind the foot 10. 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 a foot into the mouth 10 while extending in the front-rear direction, and most of the wearer's ankle and instep are exposed from the mouth 10 when worn. Therefore, when such a foot cover 20 is worn when wearing shoes such as sneakers and pumps, most of them are hidden behind the shoes and cannot be seen, and it seems that the shoes are worn with bare feet.

The front bag portion 1 located in front of the mouth 10 is formed by reciprocating knitting so as to wrap the toe from the lower half circumference of the ring portion 3 and the lower half circumference of the ring portion 3, and the top of the ring portion 3. The toe portion 2 is stitched with a stitching portion 12 by linking or the like to the half circumference portion. In addition, on both side surfaces of the toe portion 2, as a gore line 13 for forming the toe portion 2 so as to swell in a three-dimensional manner, the tip portion is divided into two parts extending forward from both ends of the stitching portion 12. A main gore line 13a is provided. In the present embodiment, the front bag portion 1 is knitted by normal knitting except for a low stretchable belt-like portion 4 and a high elastic belt-like portion 5 described later.

The sole portion 6 located below the mouth 10 is knitted by reciprocating knitting from the lower half periphery of the ring portion 3 along the sole and foot side of the wearer. The heel part 7 located behind the foot 10 is knitted by reciprocating knitting so as to wrap the wearer's heel from the back of the sole part 6. In addition, on both side surfaces of the heel portion 7, as a gore line 14 for forming the heel portion 7 so as to swell in a three-dimensional manner, the tips extend from the rear portions of the side edge portions 10 s of the wearing mouth 10 to the rear. A main gore line 14a divided into two is provided. In addition, the sole part 6 and the heel part 7 are knitted by normal knitting except for the folded part 8 described later.

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

The above is the basic configuration of the foot cover 20, but the foot cover 20 of the present embodiment has a characteristic configuration for preventing the shift of the collar portion 7 while being excellent in wearability. The characteristic configuration will be described below.

As shown in FIG. 3, the rear edge portion 10r of the wearing mouth 10 is configured as a folded portion 8 formed by folding the upper end portion of the heel portion 7 twice and stitching. Further, a rubber thread is inserted into the folded portion 8 in the weft direction. That is, the folded-back portion 8 is configured as a highly elastic portion in the left-right direction with a thickness greater than other portions. Accordingly, the rear edge portion 10r of the mouth 10 configured as the folded portion 8 can be easily hooked into the dent above the wearer's heel, and the shift of the heel portion 7 can be suppressed. Become.

Furthermore, on the inner surface of the rear edge portion 10r of the mouthpiece 10 configured as the folded portion 8, a high-friction anti-slip portion 9 (an example of an anti-slip portion) made of a high-friction material such as silicon rubber, natural rubber, or polyurethane is provided. ) Is provided. Specifically, the high-friction anti-slip part 9 is formed in a continuous linear shape extending from the center part that is the most rearward to the left and right within the formation area of the folded part 8 on the inner surface of the rear edge part 10r. In the vertical direction, it is disposed slightly above the lower edge of the folded portion 8.

The high-friction anti-slip portion 9 provided in this way is suitable for the surface above the wearer's heel due to the forward tensile force acting on the rear edge 10r from the side edge 10s of the wear mouth 10. Will be pressed against.
Further, since the high frictional slip preventing portion 9 is provided on the inner surface of the highly elastic folded portion 8, the wearing mouth 10 is spread around the wearer's ankle and a relatively large tension is applied to the folded portion 8. As a result, the high-friction anti-slip portion 9 is pressed against the surface above the wearer's heel with a relatively large force due to the large tension.
These pressing forces generate a relatively large frictional force between the high frictional slip preventing part 9 and the surface of the wearer's upper heel, and the large frictional force causes the displacement of the heel part 7 of the foot cover 20. Is preferably prevented.

Moreover, since the high-friction anti-slip part 9 is provided on the inner surface of the rear edge part 10r of the mouth 10 that is caught in the depression above the wearer's heel, the high-friction anti-slip part 9 has a certain thickness. Even when a convex portion is formed on the outer surface of the rear edge portion 10r due to the thickness thereof, the convex portion is hardly brought into contact with the inner surface of the shoe. Therefore, any deviation of the heel 7 inside the shoe caused by rubbing the convex portion against the inner surface of the shoe is suitably prevented.
Furthermore, since the high-friction anti-slip portion 9 is provided on the inner surface of the folded portion 8 having a certain thickness, most of the thickness of the high-friction anti-slip portion 9 is absorbed by the thickness of the folded portion. Therefore, the convex part resulting from the thickness of the high-friction anti-slip part 9 is hardly formed on the outer surface of the folded part 8. Therefore, the shift | offset | difference of the heel part 7 inside the shoe resulting from the convex part is suppressed more favorably.

As shown in FIGS. 1 and 2, at least a belt-shaped portion of the front bag portion 1 along the front edge portion 10 f of the mouthpiece 10 has a low-stretch belt-shaped portion that is less stretchable in the front-rear direction than the sole portion 6. 4 is provided. Specifically, the low stretchable belt-like portion 4 is a belt-like shape extending from the upper central portion to the left and right in the ring portion 3 constituting the rear side of the front bag portion 1, and as shown in FIG. It is knitted as being positioned slightly below the both ends of the front edge portion 10f of the wear mouth 10.
The both ends of the low stretchable belt-like portion 4 are provided at least on the front side portion of the front edge portion 10f of the mouthpiece 10 in the front bag portion 1 and are stretchable in the front-rear direction than the sole portion 6. Is a low stretchable part 4a.

The low stretchable belt-like portion 4 having lower stretchability than the sole portion 6 in the front-rear direction of the foot cover 20 corresponding to the waling direction (longitudinal direction) of the knitted fabric can be configured by various methods.
For example, while the sole portion 6 is knitted with a normal knitted knitting, the low expansion / contraction band-shaped portion 4 is expanded / contracted by knitting the low expansion / contraction band-shaped portion 4 with tack knitting which has a property of being difficult to stretch in the wale direction. The sex can be made lower than the sole 6.

Further, such a low stretchable low stretchable belt-like portion 4 is knitted by, for example, knitting with a splicing yarn having high elasticity or non-stretching property or a heat-sealing yarn that is cured by a subsequent heat treatment. Also, the stretchability of the low stretchable belt-like portion 4 can be reduced. Further, the low stretchable and low stretchable belt-like portion 4 can be knitted by a knitting method other than the above, for example, a knitting method such as deer knitting or rubber knitting. Further, the low stretchable belt-like portion 4 is configured as a print portion formed by fixing a vinyl chloride or silicon laminate at a high temperature, or another fabric is stitched or bonded to the knitted fabric of the low stretchable belt-like portion 4. Even with a heavy structure, the stretchability of the low stretchable belt-like portion 4 can be reduced.

Since the low stretchable belt-like portion 4 is provided on the ring portion 3 of the front bag portion 1, when the whole stretches in the front-rear direction when worn, the low stretchable belt-like portion 4 is stretched in the front-rear direction. It will be suppressed more than the sole 6. Then, the pulling force that pulls forward from the low expansion / contraction part 4a on the front side of both ends of the front edge 10f of the mouth 10 to the both ends of the front edge 10f of the mouth 10 from the low expansion / contraction band-like part 4 in particular. The tensile force is transmitted to both end portions of the rear edge portion 10r of the mouthpiece 10 through the side edge portion 10s of the mouthpiece 10.

Thus, when the pulling force pulling forward acts on both ends of the rear edge 10r of the mouth 10, the rear edge 10r of the mouth 10 is satisfactorily caught against the depression above the wearer's heel, and the state Is maintained. This can suitably prevent the buttocks 7 from shifting during walking.
Furthermore, the high-friction anti-slip portion 9 provided on the inner surface of the folded portion 8 configured as the rear edge portion 10r of the wearing mouth 10 is worn with a relatively large force by the tensile force transmitted to the rear edge portion 10r. It is pressed against the surface above the person's heel. As a result, the frictional force of the high-friction anti-slip part 9 against the surface of the wearer's upper part of the wearer is increased, and as a result, the shift of the upper part 7 of the foot cover 20 is prevented better.

In the ring part 3 knitted by circular knitting on the entire circumference in the front bag part 1, the low stretchable part 4 a which is a part of both end parts of the low stretchable belt-like part 4, particularly as shown in FIG. The portion 10f is provided at a portion on the front side of both end portions, which is a connection portion with respect to both side edge portions 10s. From this, at the time of wearing, a tensile force is favorably applied to the front end portions of the side edge portions 10s of the mouth 10 located immediately after the low stretchable portion 4a, and the rear edge of the mouth 10 The tensile force transmitted to both ends of 10r increases. Therefore, the pressing force of the high-friction anti-slip part 9 against the wearer's upper surface of the heel increases, and as a result, the heel part 7 is further prevented from shifting.

Further, since the low stretchable belt-like portion 4 is configured as a belt-like portion along the front edge portion 10f of the mouthpiece 10, a tensile force that pulls the entire front edge portion 10f of the mouthpiece 10 forward when worn. As a result, the wearer's instep is exposed more greatly from the mouth 10.

Since both ends of the reciprocating knitting are less stretchable in the wale direction, both side edges 10s of the mouth 10 configured as both end portions of the sole 6 knitted by the reciprocating knitting The stretchability in the wale direction is lower than that at the center of the bottom 6. Therefore, the tensile force transmitted from the low stretchable belt-like portion 4 to the front end portion of the both side edge portions 10s of the mouthpiece 10 is surely ensured through the both side edge portions 10s of the mouthpiece 10 having low elasticity. 10 acts on both end portions of the rear edge portion 10r, and as a result, the shift of the flange portion 7 is further prevented.

A highly elastic belt-like portion 5 having higher elasticity in the circumferential direction than the sole portion 6 is knitted in the belt-like portion that extends through the front edge portion 10f of the wear mouth 10 and covers the entire circumference. And the low expansion-contraction strip | belt-shaped part 4 is adjacently provided in the front of the substantially upper half periphery of the high elastic strip | belt-shaped part 5, and the front edge part 10f of the mouth 10 is behind the substantially upper half peripheral part of the highly elastic strip | belt-shaped part 5. Are arranged adjacent to each other.

Such a highly elastic band-like portion 5 contracts in the circumferential direction when worn, and closely adheres to a depression near the wearer's arch. This prevents the sole portion 6 from shifting in the front-rear direction. On the other hand, in the substantially upper half circumference part of the highly elastic belt-like part 5, since there is almost no depression in the wearer's instep, it is allowed to move appropriately forward. From this, the repulsive force of the low stretchable belt-like portion 4 can be suitably transmitted as a tensile force that pulls forward with respect to the front end portions of the side edge portions 10 s of the wearing mouth 10. In the present embodiment, the high-elasticity band-like portion 5 is knitted by ordinary rubber knitting, but may be knitted so as to increase elasticity by attaching a rubber thread, for example.

[Second Embodiment]
A second embodiment of the foot cover according to the present invention will be described with reference to FIGS.
The foot cover of the present embodiment is different from the foot cover of the first embodiment described above only in the shape of the low stretchable belt-like portion and the gore line. Therefore, in the following description, detailed description of the same configuration as that of the first embodiment described above may be omitted.

As shown in FIGS. 4 and 5, the low stretchable belt-like portion 40 of the foot cover of this embodiment is the same as the low stretchable belt-like portion 4 (see FIGS. 1 and 2) described in the first embodiment. In the ring portion 3 constituting the rear side of the bag portion 1, it is a belt-like shape extending from the upper central portion to the left and right, and as shown in FIG. 4, its both end portions are more than the both end portions of the front edge portion 10 f of the wearing mouth 10. It is knitted as being located slightly below.
The both ends of the low stretchable belt-like portion 40 are provided at least on the front side of the front edge portion 10f of the front mouth portion 10f in the front bag portion 1 and are more stretchable in the front-rear direction than the sole portion 6. The low stretchable part 40a is low.

Since the low stretchable belt-like portion 40 is provided on the ring portion 3 of the front bag portion 1, the low stretchable belt-like portion is formed when the whole stretches in the front-rear direction when worn as in the first embodiment. The extension in the front-rear direction at the portion 40 is suppressed more than the sole portion 6. Then, the pulling force that pulls forward from the low stretchable portion 40a on the front side of both ends of the front edge portion 10f of the mouthpiece 10 to the both ends of the front edge portion 10f of the mouthpiece 10 in particular. The tensile force is transmitted to both end portions of the rear edge portion 10r of the mouthpiece 10 through the side edge portion 10s of the mouthpiece 10.
Furthermore, in this embodiment, as shown in FIG. 5, at both ends of the low stretchable belt-like portion 40, the low stretchable portion 40 a is inclined and arranged in a state of being located outward as it is rearward. Thus, the tensile force applied rearward from the front edge portion 10f to the low expansion / contraction portion 40a can be countered by the expansion / contraction force from the upper center portion of the low expansion / contraction band portion 40 to the left and right.

In the low stretchable belt-like portion 40, the central portion 40b other than the low stretchable portion 40a is formed in a narrow belt shape that connects the front edges of the low stretchable portions 40a at both ends.
That is, the width in the front-rear direction of the central portion 40b of the low stretchable belt-like portion 40 is formed to be narrower than that of the low stretchable portion 40a. Then, in the ring part 3, since the fall of the elasticity in the front-back direction is moderately suppressed in the upper surface part along the wearer's instep where the central part 40b is arranged, low stretch such as stretching in the front-rear direction. Deterioration of the wearing feeling due to the belt-like portion 40 can be suppressed.

The foot cover of the present embodiment is provided with a plurality of sub-gore lines 13b1, 14b1, 14b2, and 14b3 that branch from the main gore lines 13a and 14a and extend downward in the gore lines 13 and 14. As a result, the sole portion and the sole portion 6 of the front bag portion 1 are sufficiently swollen by the sub-gore lines 13b1, 14b1, 14b2, and 14b3. Therefore, the expansion and contraction of the instep portion (upper surface portion) of the front bag portion 1 and the upper end portion of the heel portion 7 (the rear edge portion 10r of the mouth 10) is prevented so as to prevent the slippage and the detachment. Even if it is suppressed by 8, it does not give a tight wearing feeling to the wearer.

In particular, in the gore line 13 on the toe part 2 side, the secondary gore line 13b1 extending downward from the vicinity of both ends of the stitching part 12 near the center part of the sole part 6 and the central part of the sole part 6 in the gore line 14 on the heel part 7 side. Is provided with a sub-gore line 14b1 extending downward from the vicinity of the rear part of the side edge 10s of the mouth 10 close to the center of the foot 6 at the side edge 10s of the side edge 10s of the mouth 10. Sufficient swelling is achieved. As a result, the foot cover is in a state of wrapping the side portion of the sole of the wearer at the time of wearing, and as a result, it is possible to suitably prevent displacement and removal while realizing a good wearing feeling.
In the present embodiment, the sub-gore line 14b1 is configured to branch downward from the main gore line 14a as shown in FIG. 4, but the sub-gore line 14b1 may be separated from the main gore line 14a. For example, the auxiliary gore line 14b1 may be configured to extend from a position in front of the connecting portion of the main gore line 14a at the both side edge portions 10s of the wear mouth 10.
Also in the first embodiment described above, the configuration of the gore lines 13 and 14 described in the second embodiment can be employed.

[Another embodiment relative to the first and second embodiments]
Another embodiment of the present invention will be described. Note that the configuration of each embodiment described below is not limited to being applied alone, but may be applied in combination with the configuration of another embodiment.

(1) In the above embodiment, the high-friction anti-slip portion 9 is formed in a continuous line shape, but as shown in FIG. 6, the high-friction anti-slip portion 9 may be formed in an intermittent broken line shape. I do not care. Moreover, in the said embodiment, although the position of the high-friction antiskid part 9 in the up-down direction was a position slightly above the lower edge part of the folding | returning part 8, about the position of the said high-friction antiskid part 9 The rear edge 10r of the mouth 10 configured as the folded portion 8 can be changed as appropriate. For example, as shown in FIG. 7, a high-friction anti-slip portion 9 may be provided along the lower edge portion of the folded portion 8.

(2) In the above embodiment, the low stretchable belt-like portion 4 and the high elastic belt-like portion 5 are provided, but these may be appropriately modified or omitted. Moreover, in the said embodiment, although the both ends of the strip | belt-shaped low expansion-contraction strip | belt-shaped part 4 along the front edge part 10f of the mouth 10 in the front bag part 1 were made into the low expansion-contraction part 4a, You may provide a low expansion-contraction part only in the part of the front side of the both ends of 10 front edge parts 10f.

(3) In the above embodiment, the front bag portion 1 positioned in front of the mouth 10 is configured by the ring portion 3 knitted by round knitting on the entire circumference and the toe portion 2 knitted by reciprocating knitting. The front bag portion 1 may be knitted so as to wrap the toe only by reciprocating knitting, omitting the portion 3.

(4) In the above-described embodiment, the rear edge portion 10r of the mouthpiece 10 is configured as the folded portion 8 formed by folding the upper end portion of the heel portion 7. However, for example, rubber may be used without folding the upper end portion of the heel portion 7. The rear edge portion 10r of the mouth 10 may be formed by knitting or the like.

[Third Embodiment]
3rd Embodiment of the foot cover which concerns on this invention is described based on FIG.8 and FIG.9.
As shown in FIG. 8, the foot cover 50 of the present embodiment has a foot 10 formed on the upper surface, a front bag portion 1 positioned in front of the foot 10, and a foot positioned below the foot 10. The bottom part 6 and the collar part 7 located in the back of the foot 10 are provided. Such a foot cover 50 can be knitted integrally by a known fully automatic circular knitting machine.

The foot cover 50 is worn by inserting a foot into the mouth 10 while extending in the front-rear direction, and most of the wearer's ankle and instep are exposed from the mouth 10 when worn. Therefore, when such a foot cover 50 is worn when wearing shoes such as sneakers and pumps, most of them are hidden behind the shoes and cannot be seen, and it seems that the shoes are worn with bare feet.

The front bag portion 1 located in front of the mouth 10 is formed by reciprocating knitting so as to wrap the toe from the lower half circumference of the ring portion 3 and the lower half circumference of the ring portion 3, and the top of the ring portion 3. The toe portion 2 is stitched with a stitching portion 12 by linking or the like to the half circumference portion. In addition, on both side surfaces of the toe portion 2, gore lines 13 extending forward from both ends of the stitching portion 12 are provided in order to form the toe portion 2 so as to swell three-dimensionally. In the present embodiment, the front bag portion 1 is knitted by ordinary knitting except for a low stretchable portion 4 described later. Also, the shape of the gore line 13 can be changed as appropriate, such as dividing the tip into two parts.

The sole portion 6 located below the mouth 10 is knitted by reciprocating knitting from the lower half periphery of the ring portion 3 along the sole and foot side of the wearer. The heel part 7 located behind the foot 10 is knitted by reciprocating knitting so as to wrap the wearer's heel from the back of the sole part 6. In addition, in order to form the said collar part 7 so that it may expand | swell in three dimensions, the gore line 14 extended back from the rear part of the both-sides edge part 10s of the mouth 10 is provided in the both sides | surfaces of the collar part 7. ing. In addition, the sole part 6 and the heel part 7 are knitted by normal knitting except for the folded part 8 described later. Further, the shape of the gore line 14 can be changed as appropriate, such as dividing the tip into two parts.

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

The above is the basic configuration of the foot cover 50, but the foot cover 50 of the present embodiment has a characteristic configuration for suitably preventing displacement at the heel part 7 and the toe part 2 while being excellent in wearability. The characteristic configuration will be described below.

As shown in FIG. 8, the upper belt-like region along the rear edge 10 r of the cuff 10 in the heel part 7 is from the region knitted by normal knitting on the lower side of the upper belt-like region in the heel part 7. Also, a highly elastic heel upper end belt-like portion 20 (an example of a non-slip portion) having high elasticity is provided. The high elastic heel upper end belt-like portion 20 is knitted by knitting knitting using a highly elastic yarn such as a rubber yarn. For example, a high elastic yarn such as a rubber yarn is knitted to increase elasticity. It doesn't matter.

Further, the rear edge portion 10r of the wear mouth 10 is configured as a folded portion 8 formed by folding the upper end portion of the heel portion 7 in a double manner. Adjacent to the lower edge. In the present embodiment, the high elastic heel upper end belt-like portion 20 and the folded portion 8 are adjacent to each other, but a normal knitted portion may be interposed between them.
Further, a thread having high elasticity such as a rubber thread is inserted into the folded portion 8 in the weft direction. That is, the folded-back portion 8 is configured as a highly elastic portion in the left-right direction with a thickness greater than other portions.
By these things, the rear edge part 10r of the mouth 10 in which the folded part 8 and the highly elastic heel upper end belt-like part 20 are disposed is good in being caught in the depression above the heel of the wearer, and the heel part 7 is suppressed.

With such a configuration, when the mouth 10 expands in the front-rear direction when worn, when the mouth 10 spreads around the wearer's ankle, a highly elastic heel upper end belt provided at the rear edge 10r of the mouth 10 The part 20 and the turn-back part 8 extend along the edge of the mouthpiece 10. Then, a relatively large pulling force toward the rear is generated with respect to the rear end portions of the side edge portions 10s of the wear mouth 10.
And since such pulling force arises, the reaction force pulling forward acts on both ends of the rear edge portion 10r of the wear mouth 10 that is caught in the depression above the wearer's heel, The shift of the flange portion 7 of the cover 50 is preferably prevented.
On the other hand, this pulling force is transmitted forward through both side edges of the mouth 10, so that the pulling force toward the rear acts on both ends of the front edge 10 f of the mouth 10, For example, even when the wear mouth 10 is largely taken forward, the shift of the toe portion 2 of the foot cover 50, particularly the little finger portion, is preferably prevented.

As shown in FIG. 9, a high-friction anti-slip part 9 (an example of an anti-slip part) made of a high-friction material such as silicon rubber, natural rubber, or polyurethane is provided on the inner surface of the collar part 7. The high-friction anti-slip portion 9 is located at least on the inner surface of the high-elastic heel upper end belt-like portion 20, and specifically, has a width that slightly protrudes the high-elastic heel upper-end belt-like portion 20 in the vertical direction. Non-slip portions 9 are arranged at three locations, the center portion that is the rearmost and the left and right sides thereof.

The high-friction anti-slip portion 9 provided in this way is formed on the surface above the wearer's heel by the tension generated in the high elastic heel upper end belt-like portion 20 provided along the side edge portion 10s of the wear mouth 10. It is preferably pressed. And, by such a pressing force, a relatively large frictional force is generated between the high frictional anti-slip portion 9 and the surface of the wearer's heel, and the large frictional force of the heel portion 7 of the foot cover 50 is generated. Deviation is more preferably prevented.
In addition, about the shape and arrangement | positioning state of the high-friction antiskid part 9, it can change suitably, Furthermore, you may abbreviate | omit about the said high-friction antiskid part 9. FIG.

The sole portion 6 is provided with a plurality of side gore lines 15 extending from a plurality of locations, for example, three locations on both side edge portions 10s of the mouth 10 toward the bottom sole, Due to the part gore line 15, the sole part 6 has a sufficient bulge. Therefore, even if the tension generated in the high elastic heel upper end belt-like portion 20 is transmitted to the side edge portions 10s of the mouth 10 in order to prevent slippage and removal, it is tight for the wearer. Giving a feeling of wearing is suppressed. Note that the shape and arrangement of the side gore line 15 may be changed or omitted as appropriate.

As shown in FIG. 8, at least the belt-like region along the front edge portion 10f of the mouthpiece 10 in the front bag portion 1 is longer in the front-rear direction than the other regions knitted with normal knitting in the sole portion 6. A low stretchable portion 4 having low stretchability is provided. Specifically, the low stretchable part 4 is a ring-shaped part 3 constituting the rear side of the front bag part 1 and has a relatively narrow band shape extending from the upper central part to the left and right. The front edge portion 10f is knitted as being positioned slightly below the both end portions. The both ends of the low expansion / contraction part 4 are provided at least in the region on the front side of both ends of the front edge part 10f of the mouthpiece 10 in the front bag part 1, and are more elastic in the front-rear direction than the sole part 6. The lower part.

Also, the width of the low expansion / contraction part 4 in the front-rear direction is relatively narrow. Then, in the upper surface part along a wearer's instep, the fall of the elasticity in the front-back direction is moderately suppressed. This suppresses deterioration of the wearing feeling caused by the low stretchable part 4 such as stretching in the front-rear direction.

The low stretchable portion 4 having lower stretchability than the sole portion 6 in the front-rear direction of the foot cover 50 corresponding to the waling direction (longitudinal direction) of the knitted fabric can be configured by various methods.
For example, while the sole portion 6 is knitted with ordinary knitting, the low stretchable portion 4 is knitted with tack knitting that has a property of being difficult to stretch in the wale direction. It can be made lower than the sole 6.

Moreover, such a low stretchable low stretchable part 4 is knitted by, for example, knitting with a yarn attached with a high elasticity or non-stretchable yarn or a heat fusion yarn cured by a subsequent heat treatment. Even so, the stretchability of the low stretchable part 4 can be reduced. Further, the low stretchable / low stretchable portion 4 can be knitted by a knitting method other than the above, for example, knitting of a sword or rubber knitting. The low stretchable portion 4 is configured as a print portion formed by fixing a laminate made of vinyl chloride or silicon at a high temperature, or by stitching or bonding another fabric to the knitted fabric of the low stretchable portion 4 to form a double structure. Also, the stretchability of the low stretchable part 4 can be reduced.

Since such a low stretchable part 4 is provided in the ring part 3 of the front bag part 1, when the whole stretches in the front-rear direction when worn, the stretch in the front-rear direction in the low stretchable part 4 is the sole part. It will be suppressed from 6. Then, the pulling force toward the front from the low expansion / contraction part 4 on the front side of both ends of the front edge 10f of the mouth 10 to the both ends of the front edge 10f of the mouth 10 is particularly forward. The attracting force is transmitted to both end portions of the rear edge portion 10r of the wear mouth 10 through the side edge portion 10s of the wear mouth 10.

In this way, when a pulling force toward the front acts on both ends of the rear edge 10r of the mouth 10, the rear edge 10r of the mouth 10 is satisfactorily caught against the depression above the wearer's heel, and the state Is maintained. This can more suitably prevent the buttocks 7 from shifting during walking.
Furthermore, the high-friction anti-slip portion 9 provided on the inner surface of the high elastic heel upper end belt-like portion 20 provided at the rear edge portion 10r of the wear mouth 10 by the attracting force transmitted to the rear edge portion 10r is relatively It is pressed against the surface above the wearer's heel with great force. This increases the frictional force of the high-friction anti-slip part 9 against the surface of the wearer's upper part of the wearer. As a result, displacement of the upper part 7 of the foot cover 50 is prevented even better.

In the ring portion 3 knitted by circular knitting on the entire circumference in the front bag portion 1, both ends of the low expansion / contraction portion 4 are connected to the front edge portions 10 f of the wear mouth 10 and are connected to both side edge portions 10 s. It will be provided in the side part. From this, at the time of wearing, the attractive force toward the front is favorably applied to the front end portions of the side edge portions 10s of the mouth 10 located immediately after the both ends of the low stretchable portion 4. The pulling force transmitted to both ends of the rear edge 10r of the mouth 10 increases. Therefore, the pressing force of the high-friction anti-slip part 9 against the wearer's upper surface of the heel increases, and as a result, the heel part 7 is further prevented from shifting.

Furthermore, since the low expansion / contraction part 4 is comprised as a strip | belt-shaped part along the front edge part 10f of the wear mouth 10, at the time of wear, the attraction force toward the front of the front edge part 10f of the wear opening 10 arises ahead. As a result, the instep of the wearer is exposed more greatly from the wearing mouth 10.

Since both ends of the reciprocating knitting are less stretchable in the wale direction, both side edges 10s of the mouth 10 configured as both end portions of the sole 6 knitted by the reciprocating knitting The stretchability in the wale direction is lower than that at the center of the bottom 6. From this fact, it is ensured that the both ends of the front edge 10f of the mouth 10 and the both ends of the rear edge 10r of the mouth 10 from both side edges 10s of the mouth 10 connecting them in the front-rear direction. Since the pulling force toward the inside is transmitted, displacement at the heel part 7 and the toe part 2 is further prevented.

In the belt-like region extending over the entire circumference through the front edge portion 10f of the mouthpiece 10, a highly stretchable front belt-like portion 5 having higher stretchability in the front-rear direction than other regions knitted by ordinary knitting in the sole portion 6. Is organized. And the low expansion-contraction part 4 is provided adjacent to the front of the substantially upper half circumference part of the high expansion-contraction front strip | belt-shaped part 5, and the front edge part of the mouth 10 is behind the substantially upper half circumference part of the high expansion / contraction front strip | belt-shaped part 5. 10f are arranged adjacent to each other. In addition, in this embodiment, although the high expansion-contraction front strip | belt-shaped part 5 and the low expansion-contraction part 4 are made to adjoin, you may comprise so that a normal knitted part may be interposed between them.

The lower half circumference of the highly stretchable front belt-like part 5 located at the boundary between the front bag part 1 and the sole part 6 becomes flexible in the front-rear direction as its width changes flexibly. Therefore, even if the tension generated in the high elastic heel upper end belt-like portion 20 is transmitted to the side edge portions 10s of the mouth 10 in order to prevent slippage and removal, it is tight for the wearer. Giving a feeling of wearing is suppressed. Furthermore, along the wearer's instep, the lower half periphery of the highly stretchable front belt-like portion 5 extends in the front-rear direction and the lower surface portion of the front bag portion 1 is displaced forward with respect to the sole portion 6. Since the upper surface portion of the front bag portion 1 is displaced toward the rear mouth 10, it is possible to prevent the front bag portion 1 from being removed from the wearer's toe, particularly the little finger. Such a highly stretchable front belt-like portion 5 is knitted by rubber knitting using a highly stretchable yarn such as a rubber yarn as a front yarn, so that the front-rear direction (longitudinal direction of the knitted fabric) and the circumferential direction (of the knitted fabric) It can be configured as an improved stretchability in the weft direction. In addition, about this high expansion-contraction front strip | belt-shaped part 5, you may change or abbreviate | omit the shape and arrangement | positioning state suitably.

Therefore, in the following description, the same configurations as those of the third embodiment described above are denoted by the same reference numerals in the drawings, and detailed description may be omitted.

As shown in FIG. 10, the foot cover 51 of the present embodiment has a normal knitted knitting in the sole 6 in the belt-like region between the side edge portions 10 s of the shoe mouth 10 extending in the circumferential direction in the sole 6. A highly stretchable sole band-like portion 25 is knitted that has higher stretchability in the front-rear direction than other knitted regions.
When the width of the highly stretchable soleband portion 25 changes flexibly, the sole portion 6 excluding the side edge portions 10 s of the footwear 10 can be flexibly extended in the front-rear direction. Therefore, even if the tension generated in the high elastic heel upper end belt-like portion 20 is transmitted to the side edge portions 10s of the mouth 10 in order to prevent slippage and removal, it is tight for the wearer. Giving a feeling of wearing is suppressed. Such a highly stretchable plantar belt-like portion 25 is knitted by knitting using a highly elastic yarn such as a rubber yarn, so that the front and rear direction (vertical direction of the knitted fabric) and the circumferential direction (the weft direction of the knitted fabric) are obtained. ) With improved stretchability. Note that the shape and arrangement of the highly stretchable sole band portion 25 may be changed or omitted as appropriate.
