Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to socks, and more particularly to socks that can be easily put on and taken off and are easy to use for people who need care, such as bedridden elderly people and sick people.
[0002]
[Prior art]
In recent years, deaths due to illness and accidents have drastically decreased with the rapid advancement of medical technology, but on the other hand, the number of bedridden elderly people and sick people has been increasing, and care for bedridden elderly people and sick people has been increasing. Is a big problem.
[0003]
By the way, in socks, the side surface has a substantially square shape resembling the three-dimensional shape from the lower leg to the toe, and knitting is performed by flat knitting, mesh knitting, pile knitting, or a combination thereof, and a tightening force is applied. In general, as shown in FIG. 6, the leg portion 31, the instep portion 32, the bottom portion 33, the toe portion 34 and the heel portion 35 are covered with yarn covering yarn, specifically, Nylon-wrapped polyurethane has an appropriate stretch elasticity to fit the legs and feet of people wearing socks, while the cuff 30 is further knitted with rubber threads to prevent the socks from slipping off due to the large elasticity of the rubber threads. I have to.
[0004]
[Problems to be solved by the invention]
However, in the conventional socks, the socks are formed in a substantially square shape similar to the three-dimensional shape from the lower leg to the toes, and the mutual relationship between the instep part 32, the bottom part 33, the toe part 34, and the heel part 35 is determined. Therefore, each time a caregiver puts a sock on a bedridden elderly or sick person, it is necessary to check the instep and bottom of the sock. It was difficult, and it was very complicated because it was necessary for the caregiver to make sure that the instep and bottom of the sock were worn every time a bedridden elderly or sick person put on socks.
[0005]
In view of such problems, an object of the present invention is to provide a sock that can be easily put on and taken off and is easy to use for a person who needs care such as a bedridden elderly person or a sick person.
[0006]
[Means for Solving the Problems]
By the way, the present inventor has a double structure of a sock outer layer and a sock inner layer by being knitted and folded into a continuous cylinder, and at least the instep part, the bottom part, the leg part, and the mouth part of the sock outer layer and the sock inner layer are In addition to knitting at least one front yarn by pile knitting with a sinker on the pile, rubber yarn or covering yarn is knitted while skipping 1 to 3 stitches in the course direction, while the outer sock layer and the sock inner layer We developed a sock that was knitted with flat knitting, so that it did not feel cramped and painful, and it fits perfectly on the foot so that there is no slippage. (Application 2000-223452).
[0007]
The above-mentioned socks according to the development of the present inventors have a substantially rectangular shape on the side, and the characteristics of the sinker ride knitting allow the mouth part and the leg part to be greatly extended with a small force so that they can be easily put on and taken off. Therefore, it is found that if such socks are in a form that does not distinguish between the instep and the bottom, even elderly people who are bedridden or sick can easily put on and take off, and there is no sense of incongruity even if there is a heel on the ankle It came to do. Usually, the reason why the ankle part feels uncomfortable is that the ankle part of the sock is tightly tightened.
[0008]
[Means for Solving the Problems]
Therefore, the sock according to the present invention is a sock formed by knitting yarn and covering yarn and / or rubber yarn in a substantially square shape on the side surface, and the entire surface is substantially straight and has a continuous cylinder. And at least a part that wraps around the heel and ankle by folding back partly, and a rear part forms a double structure inside and outside, and the double structure part sinks at least one front yarn. The knitting is knitted by knitting, and the back yarn is formed by knitting rubber yarn or covering yarn while skipping one to three stitches in the course direction.
[0009]
Knitted fabric by sinker knitting has less elastic elasticity and stretches more than 2 to 3 times as much as pile knitting or plain knitting, but the rubber yarn of the back yarn or covering yarn is set appropriately Then, the large elongation characteristic is hardly impaired, and as a whole, it is possible to obtain an appropriate stretch elasticity and therefore an appropriate tightening force.
[0010]
One of the features of the present invention is that at least the rear portion of the sock is formed with a sinker and a knitted double structure from the ankle and ankle. If the rear part of the sock is knitted with a sinker, it can be put on and taken off very easily due to the large elongation characteristics of the sinker knitting. In addition, the double structure of the sinker ride knitting provides a comfortable wearing feeling that gently wraps the heel and lower leg with an appropriate tightening force and is difficult to slip off.
[0011]
Another feature of the present invention is that the entire sock has a substantially straight side surface. As a result, the mutual relationship between the instep part, bottom part, toe part and heel part is not determined, and there is no distinction between the instep part and the bottom part of the sock, so if you widen the mouth part and insert it from the toe, Can be worn.
[0012]
As a result, each time a caregiver puts socks on a bedridden elderly or sick person, it is not necessary to check the instep and bottom of the socks, eliminating the complexity of putting on socks. Because of its large stretch characteristics, it is easy to put on and take off socks while the elderly and sick people with weak strength are sleeping, making them ideal as nursing socks.
[0013]
Further, if the entire sock has a side surface that is substantially straight, the ankle can be wrinkled. However, since the portion around the ankle of the sock has a proper tightening force by knitting on the sinker, there is no sense of incongruity.
[0014]
The front portion of the sock may be any knitting method, for example, it may be knitted by flat knitting, mesh knitting, pile knitting, or a combination thereof.
[0015]
The reason for knitting rubber yarn or covering yarn with a sinker and knitting it as a back yarn while skipping 1 to 3 stitches in the course direction is to ensure appropriate stretch elasticity. There is a possibility that the leg portion and the mouth portion will slip off due to the elasticity becoming too small to endure use.
[0016]
The present invention can be applied to both socks having a short leg portion and high socks having a long leg portion.
[0017]
In the present invention, the material of the knitting yarn is not particularly limited, and cotton yarn, cotton acrylic blended yarn, wool yarn, hair acrylic blended yarn, silk yarn, silk acrylic blended yarn and the like can be used. In particular, if the outer layer of the sock's double layer is made of cotton and the inner layer of the sock is made of silk, the cotton is worn in the summer due to the excellent hygroscopicity of the cotton and the excellent moisture conditioning of the silk. When using wool or wool acrylic blended yarn, an air insulation layer is formed between the outer layer and the inner layer of the double structure, and it provides an excellent feeling of comfort that it is worn and warm in winter. It is done.
[0018]
The boundary between the double structure part and the front part of the sock may be set so that the double structure part includes at least the ankle and the heel, but the boundary between the double structure part and the front part is If it is positioned approximately in the center in the front-rear direction, there is no sense of incongruity when worn, and comfort can be guaranteed.
[0019]
In addition, the rear part of the socks wraps the heels and lower legs softly with an appropriate tightening force due to the double structure of the sinker ride knitting, and it is difficult to slip off, but there is a concern that it may fall off by being pulled to the toe side by walking etc. The In such a case, if the tightening in the vicinity of the boundary between the double structure portion and the front portion is slightly strengthened, the front portion firmly holds the front half portion of the foot, and the slippage of the double structure portion can be reliably prevented. In particular, when the boundary between the double structure portion and the front portion is set as an arch as described above, even if the tightening is slightly strengthened, there is almost no sense of incongruity and comfort is not impaired.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 5 show a preferred embodiment of a sock according to the present invention. The sock 10 has a substantially straight side as a whole, and includes a portion that wraps the heel and ankle, and the rear half portion 11 is knitted into a continuous cylindrical shape as shown in FIGS. By folding back, a double structure of the outer layer 110 and the inner layer 111 is formed, and the front portion 12 has a single structure.
[0021]
The rear portion 11 of the sock 10 is knitted by sinker knitting using 1 to 5 wool acrylic blended yarns of No. 5 to No. 24, and one No. 90 as a back yarn. It is knitted with 1st to 3rd stitches using 100th rubber thread.
[0022]
In addition, the front portion 12 of the sock 10 uses one or two No. 5 to No. 24 wool acrylic blend yarns as the front yarn, and one 200 denier or 400 denier nylon yarn or similar as the back yarn. It is knitted by pile knitting using the covering yarn of the characteristic to do.
[0023]
Here, the sinker riding knitting in this example will be described. As shown in FIG. 3, the back yarn 41 in the pile knitting is put on the head 51 of the sinker 50 in the same manner as the front yarn 40, or one to six front knitting. In this method, the yarn is knitted by placing it on the head of the sinker. In this case, both the yarns 40 and 41 are front yarns, and the rubber yarn 44 is substituted for the back yarn.
[0024]
On the other hand, pile knitting will be described. The front yarn 40 is placed on the head 51 of the sinker 50, and the back yarn 41 is knitted without being placed. Therefore, the pile height is determined by the height t in FIG.
[0025]
Accordingly, the stretcher elasticity is small in the sinker knitting, the elongation is two to three times larger than the pile knitting, and the tightening is small.
[0026]
In addition, the boundary between the rear portion 11 and the front portion 12 of the sock 10 is set so as to be approximately at the center in the front-rear direction of the arch when the sock 10 is worn. Tightening is ensured.
[0027]
When manufacturing the sock of this example, a sock knitting machine is used, and the portion corresponding to the front portion 12 is knitted, for example, by pile knitting, and the portion corresponding to the rear portion 11 is knitted with a sinker, and the whole is knitted into a substantially straight tube shape. Then, the sinker ride knitting portion is folded inward and stitched to the end of the front portion 12 to form the rear portion 11 of the double structure, while the opening edge of the tip is stitched to form the front half portion 12 as shown in FIG. The sock 10 of the example shown is obtained.
[0028]
In the sock of the present example as described above, the rear portion 11 of the sock 10 has a double structure inside and outside of the sinker knitting, so that the mouth and the subsequent portion are greatly extended with a small force due to the large elongation characteristics of the sinker knitting. It can be easily put on and taken off.
[0029]
In addition, a comfortable wearing feeling that softly wraps the legs and legs is obtained with an appropriate tightening force due to the double structure of the sinker riding knitting, and it is difficult to slip off easily.
[0030]
Further, since the entire sock 10 has a substantially straight side surface, there is no distinction between the instep part and the bottom part of the sock, and the sock can be reliably put on when the mouth is widened and inserted from the toe.
[0031]
Further, when the entire sock 10 has a substantially straight side surface, as shown in FIG. 5, a heel 13 is formed on the ankle, but the portion around the ankle of the sock 10 has an appropriate tightening force by knitting on the sinker. I don't feel uncomfortable.
[0032]
In addition, since the boundary between the double structure portion 11 and the front portion 12 is positioned at the arch, and the vicinity of the boundary is set to an appropriate tightening, it does not feel that the knitting method is different.
[0033]
Further, if the double structure portion 11 is made to have an appropriate stretch elasticity by knitting with a sinker, the double structure portion 11 may be pulled to the toe side during walking and may fall off, but the area of the arch is moderate. Therefore, the front part of the sock 10 is tightly hugged to the part from the arch to the toe of the foot, and the rear double structure part 11 is hardly pulled off.
[0034]
As a result, it is not necessary to check the front and back of the socks every time a caregiver puts socks on a bedridden elderly or sick person, eliminating the complexity of putting on socks, and the large stretch characteristics described above Therefore, it is possible to easily put on and take off socks of elderly people and sick people who are weak in force, and to take off socks. Furthermore, excellent comfort is obtained, which is most suitable as nursing socks.
