In particular, keratinization of the heel portion is remarkable, and if it becomes severe, cracks occur. Thus, Japanese Patent Application No. 3-128 discloses a sock for preventing such keratinization of the heel.
No. 872 was invented. As shown in FIG. 1, this has a double structure comprising an inner layer (1) and an outer layer (2), and a non-permeable sheet is interposed between the inner layer (1) and the outer layer (2). This sock is a bag (33) for surrounding the heel by folding the middle of a substantially rectangular non-breathable sheet in half and sewing both sides of the sock. To produce When the heel portion (10) of the inner layer (1) is extended to the extent that the feet are accommodated therein, the bag (3)
The periphery of the bag body (33) is sewn with an elastic thread (4) while forming a gathered portion so that the heel portion (10) can be surrounded in a state where the heel portion (10) is just spread.

[0003] Then, the inner layer to which the bag body (33) is attached
(1) is an outer layer formed slightly larger than the inner layer (1).
(2) Insert in And the inner layer (1) and the outer layer (2)
Sew the toes together from the front and fasten,
The production is completed by sewing the rubber band portion of the inner layer (1) to the rubber band portion of the outer layer (2).

[0004]

In the conventional socks for preventing heel dryness as described above, first, in order to manufacture the bag (33) as described above, the non-breathable sheet is cut into a special shape. This has to be sewn on, which is time-consuming. Furthermore, the work of sewing the periphery of the bag body (33) to the heel-corresponding portion of the inner layer (1) while gathering the entire periphery of the bag body (33) together with the gathers must be performed, and until the sock is completed. Process is very cumbersome, requires a lot of labor,
Productivity was poor.

The sock according to the first aspect of the present invention has an inner layer (1).
An outer layer (2) covering the entire inner layer (1), and the inner layer
An object of the present invention is to provide a method for producing a sock for drying prevention comprising an outer body of a heel portion (10) of (1) and a surrounding body (3) to improve the productivity of the product by facilitating the production. The invention according to claim 3 provides an inner layer (1), an outer layer (2) covering the entire inner layer (1), and an enclosure (3) covering the outer surface of the heel portion (10) of the inner layer (1). In the method for producing a sock for drying prevention according to the invention, when the surrounding body (3) is fixed to the heel part (10) of the inner layer (1) by sewing, the workability is improved. is there.

[0007] The sock according to the invention described in claim 7 has a productivity of socks that can prevent the heel from drying out and also prevent the area along the outside of the sole of the foot and the keratinization of the part near the base of the inside thumb. It is intended to improve.

[0007]

Means for Solving the Problems According to the first aspect of the present invention, the heel portion is stretched to the extent that the foot is accommodated therein.
Of the peripheral edge of the surrounding body (3) covered on the outer surface side of (10), only the ankle side edge and the sole side edge, or only the left and right side edges are located at predetermined positions of the heel part (10). Respectively, a step of fastening, an step of inserting the inner layer (1) to which the enclosure (3) is attached into an outer layer (2) slightly larger than the inner layer (1), and a step of inserting the inner layer (1) and the outer layer. And (2) a step of connecting the toe portions with each other and the rubber mouth portions with each other ”.

In order to fix the ankle side edge and the sole side edge, or both right and left side edges of the enclosing body (3) made of a non-breathable sheet to the heel part (10), sewing, welding, etc. Means can be adopted, whereby the entire area of the heel portion (10) of the inner layer (1) is surrounded by the surrounding body (3). The enclosure
Of the peripheral edge of (3), the place to be fixed to the inner layer (1) is as described above, so that there are few places to be fixed,
The portion other than the fastening portion is in a state of being separated from the inner layer (1). If the ankle side edge is fastened first, the surrounding body (3) is positioned at the heel part (10), and the remaining fastening is easy. Further, it is not necessary to fabricate the surrounding body (3) in a three-dimensional shape in advance by sewing.

[0009] The inner layer (1) and the outer layer (2) with the feet accommodated therein will be forcibly stretched up, down, left and right as compared to the natural state, but the size of the enclosure (3) The height and the fastening position are set so as to correspond to the heel part (10) of the inner layer (1) with the feet accommodated, so the inner layer (1) spreads when wearing socks. As a result, the fastening portion of the surrounding body (3) moves in the respective directions, and at the same time, the free portion is extended, so that the fastening portion follows the heel portion (10). Therefore, the inner layer (1) and the outer layer
The elasticity of (2) is not impaired.
The surrounding body (3) fits naturally according to the shape of the foot, and in addition to improving the feeling of use, the heel part that is easy to dry will be securely surrounded, so the heel drying prevention function is It will be sure.

Further, in some cases, the auxiliary enclosure (3) includes a pair of strips (34) (34) made of a non-breathable sheet.
If a) is fastened to both sides of the sole (11) except for the toe of the inner layer (1), it is easy to dry other than the heel, for example, a range along the outside of the sole of the foot, It is possible to manufacture a sock that can also prevent keratinization of a portion near the base of the inner thumb.

In addition, since the surrounding body (3) is in a free state except for the fastening portion at the time of use, even if the size and the shape of the foot are different, the surrounding body (3) cannot be subjected to excessive force. Is hardly added, and the durability is improved. The enclosure (3) is fixed to the outer surface of the inner layer (1), but the inner layer (1) is entirely covered by the outer layer (2), so that the enclosure (3) is not covered from the front side of the product. I can't see it.

According to a second aspect of the present invention, in the configuration of the first aspect, "the center portion of the enclosure (3) is fixed to the center of the heel portion (10) of the inner layer (1). And a step of causing it to be performed ”. In this case, in addition to the fastening portion according to the first aspect of the present invention, the center of the surrounding body (3) is also fastened to the heel (10) of the inner layer (1). As a result, there are three places where the surrounding body (3) is fixed to the inner layer (1), and the other parts are separated from the inner layer (1). The same effect as in the first aspect of the present invention is provided with respect to the extension of the surrounding body (3) due to the expansion and contraction of the socks or the above-mentioned durability.

According to a third aspect of the present invention, there is provided a method according to claim 3, wherein said ankle is a part of the periphery of said enclosure (3) which is coated on the outer surface side of said heel part (10) in a state where it is stretched to the extent that said foot is accommodated inside. Fixing the side edges and the left and right side edges only at predetermined positions of the heel portion (10), and mounting the enclosure (3) in an outer layer (2) slightly larger than the inner layer (1). A step of inserting the inner layer (1), and a step of connecting the toe portions of the inner layer (1) and the outer layer (2) to each other and the rubber mouth portions to each other. '' is there. Of the peripheral edge of the surrounding body (3), only the ankle side edge and the left and right side edges are the heel part (10).

Since the pair of strips (34) (34) are continuously provided on both sides of the ankle-side edge of the enclosure (3), the overall shape of the air-impermeable sheet provided in the inner layer (1) Has a substantially U-shape. As a result, since both sides of the heel and the sole of the foot are surrounded, all the parts that are easy to dry and rough are covered with the air-impermeable sheet. In order to fix to the inner layer (1), the sheet may be fixed along the periphery of the substantially U-shaped sheet, or the edge of the ankle side of the enclosure (3) may be fixed first and positioned. After that, the belt portions (34) and (34) may be fixed.

[0017]

As described above, according to the first aspect of the present invention, it is not necessary to fabricate the enclosure (3) in a special shape in advance, and the inner layer (1) is not required to be manufactured. Since the surrounding body (3) is fastened and the number of fastening points is reduced while spreading the legs to the extent that the feet are accommodated inside, the heel is formed of a double structure of the inner layer (1) and the outer layer (2) and It is easy to manufacture a sock for preventing the heel from drying in which the portion (10) is provided with the enclosure (3) made of a non-breathable sheet, and the productivity can be improved. In particular, when sewing and fastening, the workability is improved.

According to a second aspect of the present invention, in addition to the effects of the first aspect of the present invention, the central portion of the enveloping body (3) and the heel (10) is fixed to each other so that the enveloping body ( 3) does not shift left and right with respect to the inner layer (1). According to the third aspect of the present invention, since it is possible to sew continuously from the sole side edge of one side edge of the surrounding body (3) in a substantially U-shape, the surrounding body (3) can be sewn. ) Is sewn to the heel part (10) to fix it, thereby further improving the productivity.

According to the fourth to sixth aspects of the present invention, in addition to the effects of the first or third aspect of the present invention, the enclosure
The non-breathable sheet for (3) can be cut easily and without waste, and the fastening points of the enclosure (3) to the inner layer (1) are all straight, so the inner layer of the enclosure (3) (1) The effect that the attachment to the object becomes easier is added.
