Description

The present invention relates to leg wear worn on a foot, and more particularly to leg wear that suppresses slippage or detachment due to movements such as walking.

Legwear such as socks is used for the purpose of preventing discomfort, tiredness, and coldness when shoes (footwear) are worn directly on bare feet. For example, when shoes are worn over legwear, friction occurs between the legwear and the shoes. When the friction between the shoe and the legwear exceeds the friction between the foot and the legwear, the legwear follows the movement of the shoe rather than the movement of the foot, causing the legwear to slip or come off with respect to the foot. When the legwear is worn, if the legwear is displaced due to movements such as walking, it affects the comfort of wearing the legwear. Therefore, legwear that is unlikely to be displaced or removed is required. In particular, since the foot cover is configured to be hidden in the shoes when the shoes are put on, the area of the portion covering the feet is small, and the foot cover is liable to come off during wearing.

In order to prevent such slippage or detachment of the legwear, legwear having a resin such as silicon on the heel or sole as a non-slip has been proposed.

Patent Document 1 discloses a foot cover having a horizontally elongated shape and a non-slip shape formed of a silicone gel on the rear inner surface of the foot cover.

Patent Document 2 discloses a foot cover having a non-slip portion formed of a viscoelastic resin on the heel portion and the inner surface of the side surface of the sock. Patent Document 2 discloses a non-slip portion formed by forming three linear viscoelastic resins at a slight interval in the vertical direction.

Patent Document 3 discloses a foot cover in which a plurality of protruding elastic bodies as friction-imparting bodies are attached to the heel contact portion by printing or coating.

However, as disclosed in Cited Document 1, when a resin is used to form a horizontally elongated anti-slip shape (strip shape), slippage is caused by the low elasticity and drapeability of the resin portion. The elasticity and drapeability of the part where the stopper is formed may be impaired. Therefore, there is a problem that the degree of adhesion to the curved surface or the degree of continuous adhesion during exercise is lowered, and it is difficult to maintain the anti-slip effect. On the other hand, at the time of close contact, there is a concern that local close contact may cause skin damage such as inflammation due to friction and rash due to stuffiness.

Further, as disclosed in Cited Document 2, when a slip protection is formed by linear non-slip units arranged at intervals, the elasticity of the linear non-slip unit in the stretching direction may be impaired. be. Further, each of the linear non-slip units has a weak holding force against a curved surface due to its narrow width. Further, since the linear non-slip units are independent of each other, there is a problem that an effective effect of suppressing displacement or detachment cannot be obtained.

Further, the non-slip formed by attaching a plurality of protruding elastic bodies as disclosed in Cited Document 3 maintains the elasticity of the fabric. However, since the area where each elastic body contacts the foot is small, the individual holding force is weak. Further, since the individual elastic bodies are independent, the holding force is weakened particularly over a wide area having a curved surface (for example, a wide area of the heel). Therefore, there is a problem that the effect of suppressing displacement or detachment due to violent movement is reduced.

One aspect of the present invention has been made in view of the above problems, and an object of the present invention is to provide legwear capable of suitably suppressing slippage or detachment while suppressing a decrease in elasticity of the fabric.

In order to solve the above problems, the legwear according to one aspect of the present invention includes a main body portion having elasticity and a non-slip portion provided inside the main body portion, and the non-slip portion is provided with a non-slip portion. When a plurality of annular non-slip fragments having lower elasticity than the fabric of the main body portion are connected and the non-slip portion includes a straight portion connecting two points on the outer shell of the non-slip portion, the outer shell The straight line portion arranged inside the non-slip portion surrounded by the non-slip portion is inclined with respect to a direction for longitudinally traversing the non-slip portion and a direction for crossing the non-slip portion.

According to one aspect of the present invention, it is possible to provide legwear capable of suitably suppressing slippage or detachment while suppressing a decrease in elasticity of the fabric.

<Structure of foot cover 1>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. In the present embodiment, a case where the present invention is applied to a foot cover (leg wear) will be described as an example.

However, the present invention is not limited to the foot cover that exposes the instep and ankle, and can be applied to various leg wears that are configured to cover the instep and ankle.

FIG. 1 is a perspective view showing an external configuration of a foot cover 1 for a right foot according to the present embodiment. As shown in FIG. 1, the foot cover 1 includes a main body portion 2 worn on the foot F and a non-slip portion 3 for preventing the main body portion 2 from slipping or coming off. In the present specification, the direction perpendicular to the sole 21 is defined as the vertical direction, and the width direction of the sole 21 is defined as the lateral direction.

(Main body 2)
The main body 2 is formed of a sole 21 covering the sole of the foot, a toe 22 covering the toe, a side 23 covering both sides of the foot F, and a heel 24 covering the heel. Further, the main body 2 is provided with a cuff 2a for putting the foot in and out on the opposite side of the sole 21. The portion that is a part of the heel portion 24 and corresponds to the calcaneus B is referred to as the calcaneus portion 25.

The cuff 2a is an opening for inserting the foot F into the foot cover 1. The cuff 2a is wide open so that the instep and ankle are exposed. As a result, when the shoes (footwear) are put on, the entire main body 2 is hidden in the shoes.

The main body 2 is made of a stretchable fabric. As the fabric of the main body 2, for example, natural fibers such as cotton, linen, hair and silk, synthetic fibers such as nylon and polyester, or blended yarns thereof can be used.

In the present embodiment, the main body 2 is formed by sewing the fabric knitted by the knitting machine. However, it is also possible to weave the main body 2 with a loom.

(Non-slip part 3)
The non-slip portion 3 is provided inside the main body portion 2 in order to reduce the displacement or detachment of the main body portion 2 with respect to the foot F. The non-slip portion 3 according to the present embodiment is formed by forming a resin or the like into a sheet shape and attaching it to the inner surface of the heel portion 24 of the main body portion 2. The non-slip portion 3 may be formed by a method of providing a resin or the like at a desired position and a desired shape by a method such as silk screen.

FIG. 2 is a schematic view for explaining the shape of the non-slip portion 3 and the expansion and contraction of the non-slip portion 3. As shown by reference numeral 201 in FIG. 2, the non-slip portion 3 connects a plurality of quadrangular non-slip fragments 30 arranged so that each side exists in an oblique direction in two different directions (diagonal directions). Is formed by. In the present embodiment, the non-slip fragments 30 have the same shape and the same size. Further, the non-slip fragments 30 are arranged so as to be symmetrical. As a result, the non-slip portion 3 has a symmetrical zigzag shape as a whole. Further, inside the non-slip portion 3, a plurality of internal straight lines formed by linearly extending a part of the non-slip fragment 30 from an arbitrary end portion of the non-slip portion 3 toward the opposite end portion. A portion (straight line portion) 32 is formed. The outer shell of the non-slip portion 3 and the region surrounded by the outer shell are defined as the non-slip region 300.

As shown in FIG. 2, the non-slip fragment 30 is an annular shape having a hole portion 31 inside, and has lower elasticity than the fabric of the main body portion 2. Since the non-slip fragment 30 is an annular shape having a hole 31, it can be deformed so as to expand and contract in a predetermined direction. For example, as shown by reference numerals 202 and 203 in FIG. 2, each of the non-slip fragments 30 is deformed, so that the non-slip portion 3 is deformed so as to be able to expand and contract in the vertical direction and the horizontal direction as a whole. Here, as shown in FIG. 2, the internal straight line portion 32 is tilted in the vertical direction and the horizontal direction in the front view of the non-slip portion 3. More specifically, the non-slip portion 3 includes an internal straight portion 32 connecting two points on the outer shell of the non-slip portion 3. The internal straight line portion 32 is inclined with respect to the direction in which the non-slip portion 3 is longitudinally crossed and the direction in which the non-slip portion 3 is crossed. In other words, the non-slip portion 3 does not include a straight portion having the following features (i) to (iii). (I) It is formed by one or more non-slip fragments 30, (ii) connects two points on the outer shell of the non-slip portion 3, and (iii) traverses or traverses the inside of the non-slip portion 3 excluding the outer shell. Straight line part. As a result, it is possible to reduce the inhibition of expansion and contraction of the non-slip portion 3 in the vertical direction and the horizontal direction. Here, the vertical direction and the horizontal direction are described for ease of understanding, but the vertical direction and the horizontal direction are, in other words, the deviation of the main body 2 with respect to the skin of the foot F during movements such as walking. This is a direction in which the non-slip portion 3 is likely to occur, and the non-slip portion 3 is the main direction for suppressing the displacement of the main body portion 2. In the present embodiment, the non-slip portion 3 mainly suppresses the vertical and horizontal displacement of the main body 2 with respect to the skin of the foot F, thereby reducing the displacement or detachment of the main body 2 with respect to the foot F. .. The front view of the non-slip portion 3 means that the portion where the non-slip portion 3 is provided is viewed from a direction perpendicular to a flat surface. At this time, the lateral direction of the front view coincides with the lateral direction defined in the present specification.

The material of the non-slip fragment 30 (the material of the non-slip portion 3) is not particularly limited as long as it has a higher friction coefficient than the material of the main body portion 2. For example, a resin having a relatively large frictional resistance with the skin (natural resin such as natural rubber, synthetic resin such as silicon rubber and urethane rubber) can be used. Further, a knitting yarn having high surface friction (for example, polyester nanofiber, composite yarn containing polyurethane, etc.) may be used.

FIG. 3 is a schematic rear view for explaining the shape and arrangement of the non-slip portion 3 shown in FIGS. 1 and 2. FIG. 4 is a schematic side view of the non-slip portion 3 shown in FIG. As shown in FIGS. 3 and 4, the non-slip portion 3 is provided so as to cover a part of the calcaneus portion 25 corresponding to the calcaneus B. Further, the non-slip portion 3 is arranged symmetrically with respect to the Achilles tendon A. The area of the non-slip area 300 is not particularly limited. However, in the case of the present embodiment, 20% or more of the area of the back surface of the calcaneus is occupied in the upper or upper half of the area of the back surface of the calcaneus B (the area of the calcaneus portion 25). preferable. Thereby, it is possible to have a sufficient anti-slip effect on daily walking.

Further, the area of the non-slip portion 3 (the area obtained by excluding the hole portion 31 from the non-slip region 300) is preferably 20% or more and 50% or less of the area of the non-slip region 300. This is because if the ratio of the anti-slip portion 3 to the anti-slip region 300 is less than 20%, the anti-slip effect is reduced and an advantageous anti-slip effect cannot be obtained. Further, when the ratio of the non-slip portion 3 to the non-slip region 300 exceeds 50%, the elasticity of the non-slip region 300 is reduced. Further, considering the damage to the skin due to friction and the air permeability, the area of the non-slip portion 3 is preferably 50% or less of the area of the non-slip region 300.

The non-slip portion 3 can also be realized by lowering the elasticity as compared with the fabric of the main body portion 2 without using a resin having a high friction coefficient as described above. That is, by lowering the elasticity of the main body 2 as compared with the fabric, it can act as a stopper when the foot cover 1 is worn and suppress the displacement of the foot cover 1 with respect to the foot F.

The non-slip portion 3 having reduced elasticity is formed by, for example, cutting a separately knitted fabric into a desired shape and attaching it to a desired position with an adhesive or a thermoplastic resin. Alternatively, when knitting the fabric of the main body 2, a knitting method having low elasticity (for example, tuck knitting) is applied to a desired position, the size of the stitches (stitches) is reduced, or the knitting yarn is different from the knitting yarn. The non-slip portion 3 having low elasticity may be formed by a method such as adding a thread.

<Effect of foot cover 1>
The foot cover 1 includes a main body portion 2 having elasticity and a non-slip portion 3 provided inside the main body portion 2. The non-slip portion 3 includes a configuration in which a plurality of annular non-slip fragments 30 having lower elasticity than the fabric of the main body portion 2 are connected.

With the above configuration, the elasticity of the fabric can be ensured even in the place where the non-slip portion 3 is provided. That is, it is possible to provide a foot cover 1 capable of suitably suppressing slippage or detachment while suppressing a decrease in elasticity of the fabric.

Further, since the non-slip fragment 30 is annular, it is possible to reduce the area of the non-slip portion 3 formed of, for example, a resin. As a result, damage to the skin can be reduced. Further, since the air permeability can be ensured by the hole portion 31, there is an advantage that the occurrence of stuffiness and rash due to stuffiness can be reduced.

When the non-slip portion 3 includes a straight portion connecting two points on the outer shell of the non-slip portion 3, the foot cover 1 has an internal straight portion 32 arranged inside the non-slip portion 3 surrounded by the outer shell. It is tilted with respect to the direction in which the non-slip portion 3 is traversed and the direction in which the non-slip portion 3 is traversed. As a result, even when the internal straight portion 32 is included in the non-slip portion 3, the elasticity of the fabric in the vertical direction and the horizontal direction is less likely to be hindered by the internal straight portion 32. Therefore, the elasticity of the non-slip portion 3 in the vertical direction and the horizontal direction can be appropriately maintained.

Further, since the annular non-slip fragments 30 are connected, the non-slip portion 3 has a continuous series of shapes. As a result, the possibility of loosening or bending of the fabric in the non-slip region 300 can be reduced, and the misalignment between the non-slip fragments 30 can be reduced.

Further, the presence of the exposed portion (hole 31) of the fabric in the non-slip region 300 maintains the suppleness of the fabric, and the non-slip portion 3 fits even the skin having a curved surface such as a heel. Can be made to.

Further, the surface of the non-slip fragment 30 of the foot cover 1 has a higher coefficient of friction than the fabric of the main body 2. As a result, a good anti-slip effect can be obtained by providing the anti-slip portion 3.

Further, in the foot cover 1, when the region surrounded by the outer shell of the non-slip portion 3 is defined as the non-slip region 300, the area of the non-slip portion 3 is 50% or less of the area of the non-slip region. As a result, damage to the skin that may occur due to friction between the non-slip portion 3 and the skin can be reduced. Further, since the air permeability can be ensured, there is an advantage that the occurrence of stuffiness and rash due to stuffiness can be reduced. Further, when a resin such as silicon is used for the anti-slip portion 3, it is possible to realize the anti-slip portion 3 having a high anti-slip effect while suppressing the amount of the resin used.

Further, the non-slip portion 3 of the foot cover 1 has a shape in which a plurality of non-slip fragments 30 are connected to each other in two or more different directions. Therefore, the non-slip region 300 has desired widths in the vertical direction and the horizontal direction with respect to the curved surface of the heel. Thereby, the non-slip portion 3 having a continuous series of shapes can cover a wide area of the curved surface of the heel. That is, the anti-slip effect is improved, and the displacement between the foot F and the foot cover 1, the detachment of the foot cover 1, or the slip of the foot F in the foot cover 1 can be significantly reduced.

Further, the shape of the non-slip portion 3 of the foot cover 1 is symmetrical. As a result, the anti-slip effect can be obtained with a good left-right balance, and the effect of preventing slippage or detachment can be improved.

Further, the annular non-slip fragments 30 of the foot cover 1 have the same size and shape. As a result, the elasticity in the non-slip region 300 and the variation in the anti-slip effect can be reduced, and the anti-slip effect can be improved. In addition, the non-slip portion 3 having excellent design can be realized.

Further, when the non-slip portion 3 of the foot cover 1 includes a straight portion as a part of the outer shell of the non-slip portion 3, the straight portion constituting the outer shell is directed with respect to the direction in which the non-slip portion 3 is longitudinally crossed and the direction in which the non-slip portion 3 is crossed. Is tilted. In other words, the non-slip portion 3 does not include a straight portion extending in a longitudinal direction and a crossing direction of the non-slip portion 3 in the outer shell of the non-slip portion 3. As a result, since the outer shell of the non-slip portion 3 does not include a configuration in which the non-slip portion 3 extends in the vertical direction and the horizontal direction in the front view, the elasticity of the non-slip portion 3 can be appropriately maintained.

Further, the non-slip portion 3 of the foot cover 1 is provided on the inside of the main body portion and at least a part of the calcaneus portion 25 corresponding to the calcaneus B. As a result, it is possible to effectively prevent the foot cover 1 from coming off from the heel portion 24, which frequently occurs. Further, by providing the non-slip portion 3 on the heel bone portion 25 among the heel portions 24, it is possible to effectively suppress the friction with the shoes, particularly the displacement or detachment due to the friction with the peripheral edge of the shoe opening.

In the present embodiment, an example in which the non-slip portion 3 is provided on the heel portion 24 has been specifically described, but the non-slip portion 3 is inside the main body portion and corresponds to a curved surface of the lower leg or the foot portion. It suffices if it is provided in a portion where the skin and the fabric of the main body 2 are easily displaced due to the movement of the body. For example, it may be provided in a portion of the main body 2 corresponding to the ball of the thumb or the metatarsophalangeal joint.

That is, the non-slip portion 3 is provided inside the main body portion 2 and is provided on the portion of the main body portion 2 corresponding to the curved surface of the lower leg or the foot of the body wearing the leg wear. Thereby, with the above configuration, it is possible to suitably suppress the displacement between the skin and the fabric of the main body 2 caused by the movement of the body on the curved surface of the lower leg or the foot.

Moreover, legwear is not limited to foot covers. Examples of legwear include socks and pantyhose. When the legwear is socks, it is possible to obtain a non-slip effect and reduce the slippage of the socks by providing the legwear on the inside of the sock opening. When the legwear is pantyhose, by providing it on the inside of the waist of the pantyhose or the like, a non-slip effect can be obtained and slippage can be reduced.

<Modification example>
5 to 7 are schematic rear views showing a modified example of the non-slip portion 3 according to the present embodiment. The non-slip portion 3 may include a configuration in which a plurality of annular non-slip fragments 30 are connected, and is not limited to the above-mentioned shape.

For example, the non-slip portion 3A shown in FIG. 5 is formed by connecting substantially circular non-slip fragments 30A. In other words, the outer shell of the non-slip portion 3A includes a curved line, and the non-slip portion 3A includes a configuration in which an annular (circular or elliptical) non-slip fragment 30A composed of a curved line is connected. As shown in FIG. 5, the size of the non-slip portion 3A does not have to be constant. In FIG. 5, a plurality of non-slip fragments 30A and 30A'of different sizes are connected in a plurality of directions and irregularly, but may be connected regularly.

As another example, the non-slip portion 3B shown in FIG. 6 includes a configuration in which a plurality of non-slip fragments 30B are connected in a plurality of diagonal directions different from each other. Further, the outer shell of the non-slip portion 3B has an elliptical shape. The non-slip portion 3B may have an outer shell having an arbitrary (desired) shape as long as the non-slip portion 3B includes a configuration in which a plurality of non-slip fragments 30B are connected.

As yet another example, the non-slip portion 3C shown in FIG. 7 has a spider web-like shape as a whole of the non-slip portion 3C by connecting and arranging an annular non-slip fragment 30C composed of a straight line and a curved line. doing. In FIG. 7, a spider web-like shape is shown as an example, but the shape is not limited to this shape. By connecting the annular non-slip fragments 30C, the non-slip portion 3C as a whole may have a shape that can be an arbitrary design motif.

By applying the non-slip portions 3A to 3C, which are the above-mentioned modified examples, it is possible to provide legwear having excellent design, which can suppress a decrease in elasticity of the fabric and preferably suppress slippage or detachment. Can be done.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments obtained by appropriately combining the technical means disclosed in the different embodiments. Is also included in the technical scope of the present invention.
