Description

TECHNICAL FIELD The present invention relates to socks worn on feet, and more particularly to socks that reduce fatigue and provide comfort even during the hot summer months. The sock according to the present invention is characterized by the shape of the sole on the skin side, and other aspects (especially the length of the sock) are not limited. Regarding the length of the sock according to the present invention, starting with the low crew sock which is the most common sock length, the toe and sole including the heel are covered and the instep and ankle are exposed (the instep is covered). Including foot covers (called sock covers, inner socks, nude socks, cover socks, etc.), high socks (length below the knee), three quarter socks (calf length), boot socks (length to mid-calf), crew socks (slightly longer than low crew socks), low crew socks (most common socks), anklets (length to ankle) socks), sneaker socks (socks characterized by a very short length called step-in socks or very short socks), etc. Here, with regard to the sock according to the present invention, if you wear shoes such as sneakers (so-called athletic shoes regardless of gender, parentheses will not be repeated below), they will be hidden inside the shoes and disappear. Particularly preferred are socks, including those that are less visible to the wearer (brackets not repeated below).

Wearing shoes such as pumps on bare feet is established as fashion. In this case, if the pumps are in direct contact with the soles of the feet, sweat generated on the feet will make the inside of the shoes stuffy and uncomfortable.
Therefore, we propose a thin foot cover that covers the toe and the sole of the foot, including the heel, and exposes the instep and the ankle, and has a wide cut opening so that it is not exposed from the pump when worn. It is If you wear this foot cover and wear pumps, it looks like you are wearing pumps on your bare feet, and the foot cover is interposed between the soles of your feet and the pumps, so the inside of your shoes will get stuffy due to sweat. You can prevent it from being lost.

If you wear these foot covers and pumps (mainly women's shoes with a wide instep) and continue to stand or walk, the fabric itself is thin and cushions the sole contact surface. There is a problem that it is tired because it cannot soften the impact on the foot because it has no elasticity. In order to solve such problems, Japanese Patent Application Laid-Open No. 2014-055384 (Patent Document 1) filed by the applicant of the present application proposes that a cushioning material sufficiently exerts an effect such as a shock absorber or pain relief. To disclose a foot cover that can be

The foot cover disclosed in Patent Document 1 includes at least a sole portion covering the sole and a toe portion covering the toe, and the sole portion includes a part of the sole portion and the base of the toes. A three-dimensional three-dimensional elastic member provided corresponding to at least one of the position of the foot and the position of the arch of the foot, and a fabric that covers the elastic member and fixes the position. and

JP 2014-055384 A

The foot cover disclosed in Patent Document 1 is a result of arranging the three-dimensional cushioning material only in the positions where the cushioning effect is required, and leaving only the fabric in other parts without arranging the elastic member. , and has received a very high evaluation in that it can fully exhibit the effects of shock absorption, etc. by the cushioning material. In addition, such a configuration can be applied to general socks, and it is possible to provide socks that reduce fatigue and allow comfortable living.

By the way, the three-dimensional cushion material disclosed in Patent Document 1 (not the foot cover disclosed in Patent Document 1) is used as general socks (socks integrally knitted by a knitting machine (especially shoes such as sneakers). When used for socks that are hidden inside the shoe when worn, it is necessary to prepare a cushioning material such as three-dimensional silicone resin, elastomer, sponge, etc. separately from the knitted fabric. The material must be integrated with the knitted sock fabric so that the position does not shift (by enclosing the cushioning material in the knitted double sole or joining the cushioning material to the knitted single sole with adhesive). However, there is a problem that the manufacturing cost increases.

In addition, when wearing such socks with cushioning material in the hot summer season, the three-dimensional cushioning material is made of silicon resin, elastomer, sponge, etc., and as the wear time progresses, the shape of the sole of the foot will change. Since the cushioning material is deformed by the movement of the knitted fabric, the cushioning material and the sole of the foot come into close contact with each other through the knitted fabric.
DISCLOSURE OF THE INVENTION The present invention was developed in view of the above-mentioned problems of the prior art. To provide a sock which is hidden under a hood and disappears from view, and which can be worn comfortably by reducing fatigue even in a hot summer season.

In order to achieve the above object, the sock according to the present invention employs the following technical measures.
That is, the sock according to the present invention is integrally knitted by a knitting machine and includes at least a sole covering the sole, a toe covering the toe, and a heel covering the heel, and has an opening for putting in and taking out the foot. A sock provided on the opposite side of the sole with respect to the sole, wherein the sock includes a grid-like protrusion knitted by pile knitting at least on the skin contact side of the sole, the protrusion being , projecting closer to the skin than the portion other than the pile knitting. Here, the sock that is integrally knitted by a knitting machine is a cylindrical (circular) knitting machine that starts knitting from the opening, heel, sole, instep, and toe (however, the toe is the opening). is open) is a sock that is automatically knitted in a cylindrical shape (in this state, it is a semi-finished product), and then the open part of the toe is knitted by a machine other than the (circular) knitting machine. Sew them together to form a sock. At least one of the toe portion and the heel portion of the sock thus completed is provided with a gore line switched from the sole portion, and the toe portion is provided with a toe suture line.

Preferably, in addition to the sole portion, the grid-shaped protrusion is further provided in at least one of the toe portion and the heel portion beyond a gore line switched from the sole portion. can.
More preferably, the portion other than the pile knitting is plain knitted, and the pile knitted portion can be configured such that the sprinkling yarn inserted during the knitting of the plain knitting forms a loop.

According to the sock of the present invention, it is a sock that is integrally knitted by a knitting machine (especially a sock that is hidden inside shoes such as sneakers and becomes invisible when worn), and even in the hot summer season, It is possible to provide socks that reduce fatigue and allow comfortable living.

1 is an overall perspective view of a sock 100 according to an embodiment of the present invention worn on a foot F. FIG. It is the whole perspective view which puts the sock 100 turned inside out on the foot F. 3 is a side view seen from the direction of the white arrow in FIG. 2. FIG. FIG. 2 is a bottom view of FIG. 1 (viewed from the bottom of the foot). FIG. 3 is a bottom view of FIG. 2 (viewed from the bottom of the foot).

A sock 100 according to an embodiment of the present invention will be described in detail below with reference to the drawings.
FIG. 1 is an overall perspective view of the sock 100 worn on the foot F, FIG. 2 is an overall perspective view of the sock 100 turned inside out and worn on the foot F, FIG. 3 is a side view of FIG. 2, and FIG. A view (viewed from the sole) is shown in FIG. 4, and a bottom view of FIG. 2 (viewed from the sole) is shown in FIG.
Here, FIGS. 1 to 5 show a state in which the sock 100 is actually worn on the foot F of the wearer. That is, since the sock 100 according to the present embodiment is formed of a stretchable knitted fabric, it is in a contracted state when not shown, and it is difficult to understand the shape. is expressed in 2, 3 and 5 show the sock 100 being turned inside out and worn on the foot F for easier understanding of the present invention.

There are various structures of socks, and the present invention is not limited to a specific structure. Also, it does not matter basically what kind of material the sock is made of, how the material is patterned, and how the material is joined. Therefore, the structure of the sock 100 shown below is merely exemplary. Also, the fabric (knitted fabric) forming the sock 100 is not particularly limited, and knitting yarn for ordinary socks is widely used. It should be noted that in the description of the present invention, there is a case where the fabric and the knitted fabric are not distinguished. The sock 100 shown below is for left and right use, and is preferable in that it is not possible to mistakenly wear the left and right socks.

Furthermore, as shown in FIGS. 1 to 5, the sock 100 according to the present embodiment is integrally knitted by a knitting machine, and includes a sole portion 102 covering the sole, a toe portion 104 covering the toe, and a heel portion covering the heel. 106, and a shoe opening 108 for putting in and taking out the foot is provided on the opposite side of the sole 102 (especially, when wearing shoes such as sneakers, it is hidden inside the shoe and invisible). The sock 100 further comprises an instep part 110 covering the instep. Further, as described above, the length of the sock according to the present invention is not limited. Even if the sock has a length below the knee and has the opening 108 at the position indicated by the dotted line, the sock is called a foot cover or the like that covers the toe and the bottom of the foot including the heel and exposes the ankle as in Patent Document 1. It does not matter whether the instep is covered or not covered. Here, the sock 100 is assumed to be a sock that, when worn with shoes such as sneakers, is hidden inside the shoes and cannot be seen. The sock 100 is integrally knitted by a knitting machine, and is knitted by a cylindrical (circular) knitting machine from the opening 108 to the heel 106, the sole 102, the instep 110, and the toe. The part 104 (however, the toe part 104 in this state is in a state where the mouth is open) is a sock that is automatically knitted into a tubular shape (in this state, it is a semi-finished product), and then the toe part 104 is opened. A machine different from the (circular) knitting machine is used to sew the toe seam line 104H to complete the shape of a sock. The sock 100 thus completed has a gore line (here, a toe-side gore line 104G and a heel-side gore line 106G) switched from the sole portion 102 in at least one of the toe portion 104 and the heel portion 106, and The toe portion 104 is provided with a toe suture line 104H.

Characteristically, this sock 100 has a grid knitted with pile knitting at least on the skin-contacting side of the sole 102 (inner side in FIG. 1, outer side in FIGS. 2 and 3 showing an inverted state). It has a protrusion 120 (like a candy waffle). The projecting portion 120 protrudes closer to the skin than the portion other than the pile knitting (flat knitting portion 120F shown in FIG. 5).

By providing the grid-like projections 120 knitted by pile knitting at least on the skin-contacting side of the sole 102 in this way, the weight of the wearer of the sock 100 can be supported over the entire surface like a cushioning material. Even if the sole is highly elastic, body pressure is applied to the entire foot, which leads to foot fatigue. 120F) on the skin side, and the sock 100 is made of pile knitting in a grid pattern and is uneven and not planar, so that the body pressure that supports the weight of the wearer of the sock 100 can be dispersed, and the sock 100 can be distributed. It helps reduce fatigue.

In addition, pile knitting (regular planar rather than lattice) is often preferred for its high cushioning properties, but at the same time, it has the effect of increasing heat retention, so it gets stuffy and sweaty during the hot summer months. The amount increases and the comfort of wearing becomes less desirable. However, since the sock 100 is made of lattice-like pile knitting (lattice-like protrusions 120 knitted by pile knitting), it is uneven and not planar, so that gaps (spaces) are formed by the unevenness. Therefore, an air layer can be formed in the gap (space), and the skin contact area can be reduced, which leads to a reduction in stuffiness and perspiration. As a result, it is possible to realize socks that reduce fatigue by dispersing body pressure and that can be worn comfortably even in hot summer months by reducing stuffiness and perspiration.

More characteristically, in this sock 100, the lattice-shaped protrusions 120 knitted by pile knitting are formed on the toe portion 104 and the heel portion 106 in addition to the sole portion 102 (on the skin-contacting side). In at least one of them (in the sock 100 according to the present embodiment, both the toe portion 104 and the heel portion 106, but at least one of them is acceptable), the gore line switched from the sole portion 102 (more specifically, the toe-side gore line 104G and beyond the heel gore line 106G). In the toe portion 104 and the heel portion 106 as well, the lattice-like protrusions 120 knitted by pile knitting are present on the skin-contacting side, as in the sole portion 102 .

When the sock 100 according to the present embodiment is integrally knitted by a general sock knitting machine, the toe portion and the heel portion are formed into a bag shape by forming a gore line by rotating the knitting machine halfway. Organize into shape. In such a case, it was difficult to form pile knitting beyond the gore line with a general sock knitting machine, but by modifying the knitting machine (by developing a special pile knitting machine), Beyond the gore lines switched from 102 (more specifically, the toe-side gore line 104G and the heel-side gore line 106G), a grid-like protrusion 120 is further provided. This is particularly noticeable in FIG.

In this way, in addition to the sole portion 102, the toe portion 104 and/or the heel portion 106 can also have the grid-like protrusions 120 knitted by pile knitting, so that the body pressure can be dispersed to reduce fatigue. It is possible to realize a sock that reduces stuffiness and reduces the amount of perspiration so that you can spend more comfortably even in the hot summer season.
A further characteristic feature of the sock 100 is that, as shown in the schematic enlarged view of FIG. 120F), and in the pile knitting portion, the sprinkling yarn inserted during the knitting of the plain knitting forms a loop (loop portion 120L shown in FIG. 5).

By knitting in this way, the grid-like projections 120 knitted by pile knitting can be easily present.
The sock 100 will be described in more detail below with reference to FIGS. 1 to 5. FIG.
As shown in these figures, the sock 100 forms part of the opening 108 and is stretchable so as to wrap around the entire circumference of the foot in the lateral direction from the instep side to the sole side. It is also preferable to provide an undercarriage hold portion 110B that is knitted so as to be small and difficult to stretch. Suspension holding portion 110B is knitted so as to be less stretchable and less stretchable than the knitted fabric of instep portion 110, for example, and when sock 100 is worn, it is wrapped around the instep portion of the wearer to provide a sock. Prevents 100 from slipping off the instep. The ankle holding portion 110B is realized by knitting the instep portion with a knitted structure having low stretchability and being difficult to stretch.

Moreover, it is also preferable to provide a heel rubber knitted portion 108B at the upper end of the heel portion 106 (which forms the opening portion 108 like the foot hold portion 110B). Heel rubber knitting portion 108B is knitted with rubber knitting so as to be less elastic and less stretchable than the knitted fabric of instep portion 110, for example. The sock 100 is shrunk to prevent the sock 100 from slipping off the heel, and the sock 100 can be easily put on and taken off by grasping (picking) the heel rubber knitted portion 108B when putting on or taking off the sock 100.例文帳に追加. The heel rubber knitting portion 108B is realized by knitting the opening portion 108 of the heel portion 106 with a rubber knitting structure or the like having low stretchability and being difficult to stretch.

As described above, according to the sock according to the present embodiment (especially the sock that hides inside the shoe such as sneakers and disappears from view), the sock is integrally knitted by a knitting machine, To provide socks that reduce fatigue and allow comfortable living even in the summer season.
It should be noted that the embodiments disclosed this time should be considered as examples in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the meaning and range of equivalents of the scope of the claims.

INDUSTRIAL APPLICABILITY The present invention is suitable for socks that are integrally knitted by a knitting machine (especially socks that are hidden inside shoes such as sneakers and disappear from view when worn), and prevent fatigue even in hot summer months. It is particularly preferable in that it can be alleviated and comfortable.
