BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock, and more particularly, to a method for producing socks which is effective in preventing the dryness of the heel and soles of the sole where keratinization easily occurs.

[0002]

2. Description of the Related Art Since winter is extremely dry, the skin is easily dried and keratinized. In particular, the keratinization of the heel part is remarkable, and if it becomes severe, cracking will occur. Therefore, as a sock for preventing keratinization of such a heel, Japanese Patent Application No. 3-128
No. 872 was invented. As shown in FIG. 1, this product has a double structure consisting of an inner layer (1) and an outer layer (2), and a non-breathable sheet is interposed between the inner layer (1) and the outer layer (2). A sock of this type, wherein the sock is a bag body (33) for surrounding the heel by first folding the middle part of a substantially rectangular non-breathable sheet in two and stitching the sides of the two sides together. To produce. Then, when the heel portion (10) of the inner layer (1) is spread to the extent that a foot is accommodated inside, the bag (3
The peripheral edge of the bag body (33) is sewn with a stretchable thread (4) while forming a gather portion so that the heel portion (10) can be surrounded in a state where 3) is just extended.

Then, the inner layer to which the bag body (33) is attached

(2) Insert inside. And the inner layer (1) and the outer layer (2)
Sew each toe part from the front and fasten it,
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 sock for preventing heel dryness as described above, first, in order to manufacture the bag body (33) as described above, the non-breathable sheet is cut into a special shape. This has to be sewn on, and this alone takes time. Furthermore, it is necessary to sew 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) until the socks are completed. The process is very troublesome and requires a lot of work,
Productivity was poor.

The sock of the invention according to claim 1 has an inner layer (1)
An outer layer (2) covering the entire inner layer (1), and the inner layer
(1) A method of manufacturing a sock for preventing drying, which comprises an enclosure (3) for covering the outer surface of the heel portion (10) with the object of facilitating the manufacture and improving the productivity of the product. The invention according to claim 3 is such that the inner layer (1), the outer layer (2) covering the entire inner layer (1), and the enclosure (3) covering the outer surface of the heel part (10) of the inner layer (1). In the method of manufacturing a sock for preventing dryness consisting of, the purpose is to improve the workability when the enclosure (3) is fixed to the heel portion (10) of the inner layer (1) by sewing. is there.

[0006] The sock of the invention as claimed in claim 7 has the productivity of socks which, in addition to preventing the heel from drying, can prevent keratinization of the area along the outer side of the sole of the foot and the inner portion of the vicinity of the base of the thumb. The purpose is to improve.

[0007]

According to a first aspect of the present invention, which has been adopted to achieve the above-mentioned object, the solution means of the invention is as follows: "The heel portion is stretched to the extent that the foot is accommodated inside.
Of the peripheral edge of the enclosure (3) coated on the outer surface side of (10), only the ankle side edge and the sole side edge, or both the left and right edges are located at predetermined positions of the heel part (10). The step of fixing each, the step of inserting the inner layer (1) with the enclosure (3) attached in the outer layer (2) slightly larger than the inner layer (1), the inner layer (1) and the outer layer And (2) a step of connecting the toe parts and the mouth rubber parts to each other ”.

In order to fix the ankle side edge and the sole side edge, or both left and right side edges of the enclosure (3) made of a non-breathable sheet to the heel part (10), sewing, welding, etc. Means can be adopted, whereby the entire heel portion (10) of the inner layer (1) is surrounded by the enclosure (3). The enclosure
Of the peripheral edge of (3), since the fastening points to the inner layer (1) are as described above, the number of fastening points is small,
Except for the fastening position, the inner layer (1) is free. If the ankle side edge is fastened first, the envelope body (3) will be positioned on the heel portion (10), and the rest will be easily fastened. Further, it is not necessary to sew the enclosure (3) in advance in a three-dimensional shape.

The inner layer (1) and the outer layer (2) with the feet accommodated inside are forced to be stretched vertically and horizontally as compared with the natural state, but the size of the enclosure (3) is large. Since the seat and fastening position are set so as to correspond to the heel portion (10) of the inner layer (1) with the foot accommodated, the inner layer (1) is spread when the socks are put on. Thus, the fastening portion of the envelope body (3) moves in each direction, and the free portion extends so as to extend along the heel portion (10). Therefore, the inner layer (1) and the outer layer
The elasticity of (2) is not impaired, and when worn,
The enveloping body (3) naturally fits according to the shape of the foot, improving the feeling of use and securely enveloping the heel part, which is easy to dry, so that it has a function of preventing the heel from drying. It will be certain.

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

In addition, since the envelope body (3) is in a free state except for the fastening portion at the time of use, even if the size and shape of the foot are different, it is impossible to force the envelope body (3). Is less likely to be added and durability is improved. This enclosure (3) is attached to the outer surface of the inner layer (1), but since this inner layer (1) is entirely covered by the outer layer (2), the enclosure (3) is not visible from the front side of the product. I can't see it.

The invention according to claim 2 is the structure of the invention according to claim 1, wherein "the central portion of the enclosure (3) is fixed to the center of the heel portion (10) of the inner layer (1). It is characterized in that it is provided with a step of performing. In this case, in addition to the fastening portion of the invention of claim 1, the central portion of the enclosure (3) is also fastened to the heel portion (10) of the inner layer (1). As a result, the number of fastening points of the enclosure (3) to the inner layer (1) becomes three, and the rest of these three points are released from the inner layer (1). With respect to the spreading of the enclosure (3) due to the expansion and contraction of the socks, the durability, and the like, there is the same effect as the invention of claim 1.

According to a third aspect of the present invention, "the ankle of the periphery of the enclosure (3) covered on the outer surface side of the heel portion (10) in a stretched state to accommodate the foot inside Attaching only the side edges and the left and right side edges to predetermined positions of the heel portion (10) respectively, and attaching the enclosure (3) to the 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 parts of the inner layer (1) and the outer layer (2) and the mouth rubber parts to each other ”. is there. Of the periphery of the enclosure (3), only the ankle side edge and the left and right side edges are the same as the heel part (10).
Since it is configured to be fastened to the
It will have a substantially U shape. Therefore, the enclosure (3)
If the fastening step of is to be sewn using a sewing machine or the like, sew continuously from the foot bottom side edge of one side edge of the enclosure (3) so as to draw a substantially U-shape. Can be attached. Also, if the ankle side edge of the enclosure (3) is fixed to the inner layer (1) at a predetermined position first, it is impossible to continuously sew in the U-shape as described above, Since the body (3) is positioned on the inner layer (1), it is easy to sew the left and right edges of the remaining surrounding body (3).

The invention according to claims 4 to 6 is characterized in that, in the constitution of the invention according to claim 1 or 3,

(1) is inserted, and the step of connecting the toe parts of the inner layer (1) and the outer layer (2) and the mouth rubber parts to each other ”is performed.

Since the pair of strip-shaped portions (34) (34) are connected to both sides of the ankle side edge of the enclosure (3), the whole shape of the non-breathable sheet provided in the inner layer (1) is formed. Has a substantially U shape. As a result, the heel and both sides of the sole of the foot are surrounded, so that all the places that are easy to dry and easily become rough are covered with the non-breathable sheet. In order to fix it to the inner layer (1), it may be fixed along the periphery of the substantially U-shaped sheet, or first, the ankle side edge of the enclosure (3) is fixed and positioned. However, after that, the band-shaped portions (34) (34) may be fixed.

[0017]

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

According to the invention of claim 2, in addition to the effect of the invention of claim 1, the enclosure (3) and the heel portion (10) are fastened to each other at the central portions thereof, so that the enclosure ( The effect that 3) does not shift to the left and right with respect to the inner layer (1) is added.
