Description

The present invention relates to a sock made of a tubular knitted fabric, and more particularly to a sock capable of suppressing wrinkles from being generated at a bent portion on the front side of the tubular knitted fabric.

Conventionally, the bent part on the front side of the sock (near the boundary between the body part covering from the shin to the ankle and the foot part covering the instep, sole and toes) has a side shape that bends at a steep angle when worn. Wrinkles are likely to occur in. It is considered that the knitted fabric of the sock does not bend smoothly at this bent portion (the front side of the wearer's ankle) and wrinkles occur. In order to prevent the occurrence of this wrinkle, it is originally preferable to thin the knitted fabric of the entire bent portion of the sock, but if the knitted fabric of the entire bent portion of the sock is thinned, the tightening force of the ankle can be maintained. become unable.

From this point of view, Japanese Patent No. 5165122 (Patent Document 1) discloses a footwear made of a tubular knitted fabric knitted in a circular knitted fabric and having at least a body part and a foot part. This footwear includes a toe portion, which is a toe-molded portion corresponding to the wearer's toe in the tubular knitted fabric, a heel portion, which is a heel-molded portion corresponding to the wearer's heel in the tubular knitted fabric, and a heel portion. A figure eight part that is organized as the foot part excluding a part of the body part and the toe part and the heel part and supports the ankle joint of the wearer, and one end is connected to the toe part in the figure eight part. The other end is connected to the body part excluding the figure eight part, and the holding part extending to the front side of the tubular knitted fabric and the knitted fabric excluding the holding part in the figure eight part. A support portion continuous between the holding portion and the heel portion is provided over the body portion and the foot portion, and the expansion / contraction resistance of the support portion in the length direction of the tubular knitted fabric is the length of the tubular knitted fabric. It is characterized in that it is larger than the expansion / contraction resistance of the holding portion in the direction.

Further, this footwear is provided with a wrinkle suppressing portion extending in the circumferential direction at a bent portion on the front side of the tubular knitted fabric, and the expansion / contraction resistance of the wrinkle suppressing portion in the length direction of the tubular knitted fabric is increased. It is characterized in that it is smaller than the expansion / contraction resistance of the holding portion in the length direction of the tubular knitted fabric. This wrinkle suppressing part is a knitted fabric that extends in the circumferential direction of the sock to a part of the holding part, so that the wrinkles generated in the bent part of the sock are eliminated while maintaining the tightening force of the ankle by the figure eight part. be able to.

Japanese Patent No. 5165122

In the sock (footwear) disclosed in Patent Document 1, three substantially rectangular wrinkle suppressing portions are arranged side by side in the length direction of the sock.
However, with such a shape, wrinkles generated at the bent portion cannot be sufficiently suppressed.
The present invention has been developed in view of the above-mentioned problems of the prior art, and an object of the present invention is preferably that a sock made of a tubular knitted fabric has wrinkles on a bent portion on the front side. It is to provide socks that can be suppressed.

In order to achieve the above object, the socks according to the present invention have taken the following technical measures.
That is, the sock according to the present invention is a sock made of a tubular knitted fabric having a longitudinal direction from the opening to the toe portion through the heel portion, and is formed on a bent portion on the front side of the tubular knitted fabric. A narrow-shaped wrinkle suppressing portion extending in the circumferential direction, which is the lateral direction, is provided, and the knitting density of the wrinkle suppressing portion is the knitting density (knitting density) of a tubular knitted fabric other than the wrinkle suppressing portion in the bent portion. As an example, the number of knitting yarns per unit area is smaller than the size (the knitting is not clogged and the knitting is coarse, and the wrinkle suppressing part is longer than the knitting part because the knitting is clogged. The shape of the wrinkle suppressing portion is thinner on the left and right sides than the front side of the tubular knitted fabric, and / or is curved from the front side to the left and right sides of the tubular knitted fabric.

Here, the difference in knitting density between the wrinkle suppressing portion and the tubular knitted fabric other than the wrinkle suppressing portion in the bent portion is replaced with the difference in stretching resistance, and the stretching resistance of the wrinkle suppressing portion is the stretch resistance in the bent portion. It may be smaller than the expansion / contraction resistance of the tubular knitted fabric other than the wrinkle suppressing portion (the wrinkle suppressing portion is easier to stretch than the part other than the wrinkle suppressing portion). It should be noted that such a difference in expansion / contraction resistance may be realized by knitting by adopting knitting yarns having different elasticity.

According to the sock of the present invention, it is possible to suitably suppress the occurrence of wrinkles in the bent portion on the front side in the sock made of the tubular knitted fabric.

It is the schematic side view (A) and schematic top view (B) of the sock (for right foot) which concerns on embodiment of this invention. It is a schematic side view when the sock of FIG. 1 is worn on the user's (right) foot F. It is a schematic perspective view when the sock of FIG. 1 is worn on the user's (right) foot F. It is a schematic top view of the sock which concerns on the modification of embodiment of this invention.

Hereinafter, the socks according to the embodiment of the present invention will be described in detail with reference to the drawings. Here, there are various structures of socks, and the present invention is not limited to a specific structure, and any sock structure may have features described later. The knitting structure and yarn of the knitted fabric that constitutes the sock may be any. Therefore, the sock structure itself shown below is merely an example. The present invention is particularly preferable for socks having a length up to about an anklet, which is called anklet type.

Further, the socks shown below are preferable in that the left and right socks can be designed separately instead of being shared on the left and right, or the left and right pairs can have a unified design, but the left and right socks are preferable in that the left and right are not mistakenly worn.
1 (A) is a schematic side view of the sock 100 (for one right foot of the left and right pair) according to the present embodiment, and FIG. 1 (B) is a schematic top view thereof, which is FIG. 2 (A) and FIG. FIG. 2B is a schematic side view when the sock 100 is worn on the user's right foot F, and FIGS. 3A and 3B are schematic perspective views in that case. It should be noted that FIGS. 1 (A) and 1 (B) are views in which the sock 100 before wearing is folded flat and placed on a flat surface, and is not a view assuming wearing.

In FIGS. 1 to 3, the sock 100 includes an annular body portion 104 that constitutes the opening (drilling opening) 102 to the heel portion 110 and covers from the shin (or under the shin, the same applies hereinafter) to the ankle portion, and the heel portion. It includes an annular foot portion 106 that constitutes from 110 to the toe portion 108 and has a closed tip that covers the instep, sole, and toes.
The opening 102 is preferably composed of rubber knitting or a knitting structure similar thereto, or a knitting structure into which a rubber thread is inserted. For example, using a circular knitting machine, the opening 102 is knitted by rubber knitting or flat knitting into which rubber threads are inserted to increase the tightening force and prevent the sock 100 from slipping off.

The knitting structure of the opening 102, the body part 104, and the foot part 106 is not particularly limited, and is a knitting structure similar to that of conventional socks, for example, a flat knitting structure (also referred to as knitting, knitting, or jersey). Be organized. Although the knitting structure is not particularly limited as described above, as will be described later, the sock 100 has a tubular knitting on the bent portion (near the boundary between the body portion 104 and the foot portion 106) on the front side of the tubular knitted fabric. It is characterized in that a narrow wrinkle suppressing portion 120 extending in the circumferential direction, which is the lateral direction of the ground, is knitted. In these wrinkle suppressing portions 120, the knitting density of the wrinkle suppressing portion 120 is smaller than the knitting density of the tubular knitted fabric other than the wrinkle suppressing portion 120 at the bent portion, and the expansion / contraction resistance (tightening force) is small.

Here, the method of changing the knitting density includes changing the knitting structure. For example, a tubular knitted fabric other than the wrinkle suppressing portion 120 at the bent portion may be knitted by knitting as described above, and the wrinkle suppressing portion 120 may be knitted by tuck knitting. Further, the elastic resistance (tightening force) is knitted instead of the knitting density (including the change of the knitting structure) so that the wrinkle suppressing portion 120 is smaller than the tubular knitted fabric other than the wrinkle suppressing portion 120 at the bent portion. It is also possible to knit the wrinkle suppressing portion 120 by changing the elastic force of the knitting yarn of the structure (using a knitting yarn having a small elastic force).

Except for these features, the sock 100 is knitted in the same manner as a normal sock. For example, the heel portion 110 constituting the foot portion 106 is knitted by reducing and increasing the number of stitches around the gore line (not shown) many times. The toe portion 108 constituting the foot portion 106 is knitted by starting knitting from the sole side and reducing and increasing the number of stitches around the gore line many times. Except for the toe portion 108, the heel portion 110, and the wrinkle suppressing portion 120 in the foot portion 106, the foot portion 106 is knitted with an arbitrary structure such as flat knitting.

The wrinkle suppressing portion 120, which is a characteristic configuration of the sock 100, will be described. The sock 100 is not limited to the wrinkle suppressing portion 120 at three locations (not limited to the three locations) at the bent portion (near the boundary between the body portion 104 and the foot portion 106) on the front side. (Specifically, the first wrinkle suppressing portion 120A, the second wrinkle suppressing portion 120B, and the third wrinkle suppressing portion 120C from the opening 102 side) are provided.

As shown in FIGS. 1 to 3 (particularly FIG. 1 (B)), the wrinkle suppressing portion 120 is formed in the bent portion on the front side of the tubular knitted fabric in the lateral direction of the tubular knitted fabric forming the sock 100. It is a narrow shape extending in the circumferential direction, and the shape is narrower on the left and right sides than the front side of the tubular knitted fabric (width W (1)> width W (2)> width W (3). ) And it is curved from the front side to the left and right side of the tubular knitted fabric (so-called crescent shape).

As shown in FIG. 1 (B), although not limited, the first wrinkle suppressing section 120A, the second wrinkle suppressing section 120B, and the third wrinkle suppressing section 120C have the same shape and the first wrinkle suppressing section 120C. The portion 120A and the second wrinkle suppressing portion 120B have the same bending direction, and the third wrinkle suppressing portion 120C has a different bending direction from these. More specifically, in the first wrinkle suppressing portion 120A and the second wrinkle suppressing portion 120B, the tip of the tubular knitted fabric of the sock 100 in the lateral direction is bent toward the opening 102, and the third wrinkle suppressing portion 120C The tip of the tubular knitted fabric of the sock 100 in the lateral direction is bent toward the toe portion 108.

The second wrinkle suppressing portion 120B may be curved in the same direction as the third wrinkle suppressing portion 120C. However, when two or more wrinkle suppressing portions 120 are provided, the wrinkle suppressing portion 120 on the opening 102 side (here, the first wrinkle suppressing portion 120A) and the wrinkle suppressing portion 120 on the toe portion 108 side (here, the third). It is preferable that the bending direction is different from that of the wrinkle suppressing portion 120C), and in those bending directions, the tip of the wrinkle suppressing portion 120 on the opening 102 side is bent toward the opening 102 and curved. It is preferable that the tip of the wrinkle suppressing portion 120 on the toe portion 108 side is bent toward the toe portion 108 side in the lateral direction.

As shown in FIGS. 2 and 3, when the user wears the sock 100 having such a feature on the foot F, the bent portion (near the boundary between the body portion 104 and the foot portion 106) on the front side thereof. Although the wrinkles are generated differently between the central part and the end part of the tubular knitted fabric in the lateral direction due to the three-dimensional shape of the foot (wrinkles tend to occur largely in the central part and the end part). Wrinkles can be suitably suppressed by the following actions and effects.
-First action effect Since the width of the wrinkle suppressing portion 120 is narrower on the left and right sides than the front side of the tubular knitted fabric (width W (1)> width W (2)> width W (3)). In the central part where wrinkles tend to occur greatly, the wrinkle suppressing part having a large width (W (1)) acts greatly, and the area where there are few knitting yarns is large (and / or because the area where the elastic force is weak is large). Wrinkles that tend to occur large can be suitably suppressed, and at the ends where wrinkles tend to occur small, the wrinkle suppressing portion having a small width (W (3)) acts small, and a region with few knitting yarns is formed. Since it is small (and / or because the region where the stretching force is weak is small), wrinkles that tend to occur small can be suitably suppressed.
-Second action / effect Since the wrinkle suppressing portion 120 is curved from the front side to the left and right sides of the tubular knitted fabric, the wrinkle suppressing portion 120 having less knitting yarn (and / or weak elastic force) is used as the wrinkle suppressing portion 120. Since the tubular knitted fabric other than the above is strongly pulled toward the opening 102 side or the toe 108 side (the direction of the white arrow or the black arrow shown in FIG. 1 (B)), wrinkles can be suitably suppressed. That is, in the first wrinkle suppressing portion 120A (and the first wrinkle suppressing portion 120B), the first wrinkle suppressing portion 120A (and the first wrinkle suppressing portion 120B) is pulled toward the opening 102 side (in the direction of the white arrow shown in FIG. 1B) by the tubular knitted fabric. In the wrinkle suppressing portion 120C of No. 3, the wrinkle suppressing portion 120C is pulled toward the toe portion 108 side (in the direction of the black arrow shown in FIG. 1 (B)) by the tubular knitted fabric, and wrinkles can be suitably suppressed at this bent portion. it can.
-Third action / effect Since a plurality of (three in this case) wrinkle suppressing portions 120 are provided (by changing the bending direction thereof), the above-mentioned actions (1) and (2) are synergistically expressed. Therefore, the occurrence of wrinkles in the bent portion can be suppressed extremely suitably.

As described above, in the sock 100 according to the present embodiment, the short side of the tubular knitted fabric is formed on the bent portion (near the boundary between the body portion 104 and the foot portion 106) on the front side of the tubular knitted fabric. A narrow-shaped wrinkle suppressing portion 120 extending in the circumferential direction is knitted, and the knitting density of the wrinkle suppressing portion 120 is smaller than the knitting density of the tubular knitted fabric other than the wrinkle suppressing portion 120 at the bent portion, and the knitting density is expanded and contracted. The resistance (tightening force) is small. Further, the shape of the wrinkle suppressing portion 120 is narrow, narrower on the left and right sides than the front side of the tubular knitted fabric, and curved from the front side to the left and right sides of the tubular knitted fabric. Since it has a so-called crescent-shaped shape, it is possible to suitably suppress the occurrence of wrinkles in the bent portion on the front side when the sock 100 is worn.

<Modification example>
In the following, the sock 200 and the sock 300 according to the modified example of the present embodiment will be described with reference to FIG. The sock 200 and the sock 300 include a wrinkle suppressing portion 220 and a wrinkle suppressing portion 320 having a shape different from that of the wrinkle suppressing portion 120 of the sock 100 according to the above-described embodiment. The wrinkle suppressing unit 220 and the wrinkle suppressing unit 320 correspond to the wrinkle suppressing unit 120, respectively. More specifically, the wrinkle suppressing part 220A and the wrinkle suppressing part 320A are in the wrinkle suppressing part 120A, the wrinkle suppressing part 220B and the wrinkle suppressing part 320B are in the wrinkle suppressing part 120B, and the wrinkle suppressing part 220C and the wrinkle suppressing part 320C are in the wrinkle suppressing part 120C. Corresponds to each. Other structures that are the same as those in the embodiment are designated by the same reference numerals as those in the embodiments. The explanations thereof will not be repeated here because they overlap with the above explanations.

The shape of the wrinkle suppressing portion 120 of the sock 100 described above is narrower on the left and right sides than the front side of the tubular knitted fabric (width W (1)> width W (2)> width W (3)) and is tubular knitting. It had a so-called crescent shape that was curved from the front side to the left and right sides of the ground, but the shape of the wrinkle suppressing portion 220 of the sock 200 shown in FIG. 4 (A) is on the left and right sides of the front side of the tubular knitted fabric. Although it is thin (width W (4)> width W (5)> width W (6)), it is not curved from the front side to the left and right side of the tubular knitted fabric, and the wrinkles of the sock 300 shown in FIG. 4 (B). The shape of the restraining portion 320 is the same on both the front side and the left and right sides of the tubular knitted fabric (all widths W (7)), but is curved from the front side to the left and right sides of the tubular knitted fabric.

Even in the sock 200 shown in FIG. 4 (A), since the above-mentioned first action and effect are exhibited, it is possible to suitably suppress the occurrence of wrinkles in the bent portion of the sock 200.
Even in the sock 300 shown in FIG. 4 (B), since the above-mentioned second action effect is exhibited, it is possible to preferably suppress the occurrence of wrinkles at the bent portion of the sock 300.
Also in the socks 200 shown in FIG. 4A and the socks 300 shown in FIG. 4B, by providing a plurality of wrinkle suppressing portions 220 and wrinkle suppressing portions 320 (here, three), the above-mentioned third action effect Wrinkles can be suitably suppressed from the occurrence of wrinkles at the bent portions of the sock 200 and the sock 300.

It should be noted that the embodiments disclosed this time are examples in all respects and are not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

The present invention is preferable for a sock made of a tubular knitted fabric having a longitudinal direction from the opening to the heel to the toe, and it is possible to preferably suppress the occurrence of wrinkles on the bent portion on the front side of the sock.
