Description

  The present invention relates to a sock, and more particularly to a sock that can be comfortably worn by sick and elderly people with sensitive skin.

  In general socks, as shown in FIG. 11, the leg portion 31, the instep portion 32, the bottom portion 33, the toe portion 35, and the heel portion 34 are covered yarn covering yarns, specifically, nylon wound polyurethane. While fitting to the leg and foot of a person wearing socks by moderate elastic elasticity, the shoe part 30 is further knitted with rubber thread to prevent the sock from slipping down due to the large elastic elasticity of the rubber thread ( Patent Document 1 and Patent Document 2).

  However, in the above-described socks, if the elastic elasticity of the cuff part 30 or the entire sock is increased so as to surely prevent the sock from being displaced, the part of the cuff or the entire leg is tightened tightly, and it is painful if worn for a long time. On the other hand, if the elastic elasticity of the cuff portion 30 or the entire sock is reduced, the feeling of cramping is eliminated, but the sock does not fit, and deviation tends to occur.

  On the other hand, the present applicant forms a double structure of the sock outer layer and the projecting inner layer by being knitted and folded into a continuous cylindrical shape, and at least the instep part, the bottom part, the leg part, and the sock outer layer and the sock inner layer. The mouth part is knitted by pile knitting with one or more front yarns and knitting with 1 to 3 stitches of rubber yarn or covering yarn in the course direction as the back yarn, while the outer layer of the socks and the inner layer of the socks Has developed and proposed a sock knitted with flat knitting (Patent Document 3).

  It was found that this sock wraps softly and does not feel cramped and painful, fits perfectly on the foot, and is very comfortable to wear.

Japanese Patent Laid-Open No. 10-168605 Japanese Patent Laid-Open No. 10-158903 Japanese Patent Laid-Open No. 2002-38304

  However, it has been found that the socks described in Patent Document 3 still have a feeling of pressure for sick people and elderly people with sensitive skin sensations.

  In view of this point, an object of the present invention is to make it possible to comfortably wear a sick person or an elderly person with sensitive skin.

  Therefore, the sock according to the present invention is a sock in which both ends of the cylindrical shape are opened and one end thereof is a cuff part, and the curved outer side part is a heel part covering the heel. The sock outer layer and the sock inner layer are formed into a double structure by being knitted and folded into a continuous cylinder, and the portion other than the heel portion of the sock outer layer and the sock inner layer is pile knitted with one or more front yarns While knitting with a sinker knitting or flat sinker knitting, and knitting while skipping one to three stitches of rubber yarn or covering yarn in the course direction as the back yarn, the heels of the sock outer layer and the sock inner layer The part is knitted by flat knitting.

  When observing the three-dimensional shape of the foot, there are various shapes, such as a foot that is the same size, wide at the instep, narrow at the instep, wide at the instep, and low at the instep. Even if it is said to be high or low, wide or narrow, the degree varies from person to person. Therefore, if the size of the sock is defined by the size of the foot even when knitting with the sock knitted as described in Patent Document 3, the feeling of wearing is different, and a person with sensitive skin feeling such as a sick person or an elderly person still has a feeling of pressure. It is thought that there was.

  On the other hand, the basic function of socks is to cover and protect the area from the toes to the ankles (or lower legs), and thus keep it warm. If the part is covered with socks, the function of protecting the feet and keeping warm can be almost achieved. The applicant knitted one or more front yarns by pile knitting with a sinker and knitted rubber yarn or covering yarn as the back yarn while skipping 1 to 3 stitches in the course direction, and leg leg part Has developed and proposed a cylindrical supporter (Japanese Patent Application No. 2004-175494)

  One of the characteristics of the present invention is that the sock is formed in a substantially square-shaped side surface so that the toe of the foot, the instep and the sole, or the toe of the foot, the instep and the arch are projected from the tip of the sock. is there.

  As a result, it is possible to reliably eliminate the feeling of pressure felt by socks with a sick person or elderly person with sensitive skin sensations. In addition, in the case of a person who has broken a toe, if the toe of the sock is closed, it is very difficult to wear due to treatment plaster etc. Even if there is gypsum, it can be worn lightly.

  The knitted fabric by pile knitting on the sinker has low elastic elasticity and the elongation is 2 to 3 times that of pile knitting or flat knitting. Is hardly damaged, and as a whole, it is possible to obtain an appropriate stretch elasticity, and thus an appropriate tightening force.

  Further, it has been found that even when flat knitting sinker knitting is adopted instead of pile knitting sinker knitting, large elongation characteristics and appropriate stretch elasticity can be obtained as in pile knitting sinker knitting. However, in the case of flat knitting sinker knitting, it is necessary to increase the number of knitting needles compared to the case of pile knitting sinker knitting. For example, if the knitting needle is 140 in the case of pile knitting sinker riding, the knitting needle needs to be about 160 in the case of flat knitting sinker knitting.

  Another feature of the present invention is that the outer layer of the sock and the inner layer of the sock have a double structure, and the surface yarns of the inner and outer layers are pile knitted or flat knitted. As a result, it is possible to obtain a comfortable wearing feeling that gently wraps the body, for example, legs, legs, and hands, with a large stretch characteristic and a moderate tightening force, and at the same time ensures that the tubular knitted body slides down with a moderate tightening force. Can be prevented.

  As a result, it is not necessary to increase the tightening force of the mouth part by knitting rubber yarn into the mouth part, and the part of the mouth does not bite and feel no pain. The cuff portion can be knitted with an appropriate elastic elastic rubber thread as required.

  Also, because of the large stretch characteristics of pile knitting sinker knitting or flat knitting sinker knitting, the entire sock stretches with a small force, so it can be easily worn by elderly people and sick people with weak limb strength, It can also be easily removed when taking off.

  Loads are most easily applied to the socks from the heel of the foot, and if the entire sock is made of a double knitted pile knitting or flat knitting sinker knitting, the outer layer of the sock is caused by the load applied from the heel. It tends to shift forward with respect to the inner layer, and the sock tends to come off due to heels.

  Still another feature of the present invention is that flat knitting is adopted for the heel portion. As a result, even when a load is applied to the double overlapped part in flat knitted fabric, the mutual displacement is smaller than in pile knitted sinker knitted or flat knitted sinker knitted, while wearing socks In addition, the sock outer layer is less likely to be displaced forward relative to the sock inner layer.

  In order to reliably eliminate the feeling of pressure, it is preferable to appropriately change the position of the cylindrical tip opening according to the three-dimensional shape of the foot, the size of the plaster, and the like. That is, the outer sock layer and the sock inner layer are preferably dimensioned so that the other end openings are located immediately before the heel, immediately after the arch or just after the toes.

  Further, the height of the mouth portion of the sock can be arbitrarily selected from the ankle to the above the knee. That is, the sock outer layer and the sock inner layer can be dimensioned so that the mouth portion is located just above the ankle, calf, knee, just below the knee, or just above the knee.

  Also, the rubber yarn or covering yarn is knitted while skipping one or three stitches in the course direction as a back yarn in pile knitting or flat knitting sinker knitting, so as to ensure an appropriate stretch elasticity. For this reason, when the number is three or more, the elastic elasticity becomes too small to endure use.

  In the present invention, the material of the knitting yarn is not particularly limited, and cotton yarn, cotton acrylic blended yarn, wool yarn, wool acrylic blended yarn, silk yarn, silk acrylic blended yarn and the like can be used, but the outer layer knitting yarn is cotton yarn, inner layer The silk thread is made of silk and has excellent hygroscopicity due to cotton and excellent hygroscopicity and heat absorption due to silk, so it is cool to wear during summer and between the outer and inner layers that form a double structure. An air-insulating layer is formed, and an excellent wearing feeling is obtained that it is worn and warm in winter.

  In addition, when applying a flat knitting sinker knitting and knitting structure while knitting the back yarn in the course direction to one or three stitches when applied to normal socks, the normal person feels softly wrapped and feels tight and painful. There is nothing, and it fits perfectly on the foot, making it a very comfortable sock.

Therefore, the sock according to the present invention is a sock composed of a toe part, an instep part, a bottom part, a heel part, a leg part, and a cuff part. The upper part of the sock outer layer and the inner layer of the sock, the leg part, and the mouth part of the sock are knitted with one or more front yarns in a flat knitted sinker knitting, and a rubber yarn or covering as a back yarn The yarn is knitted while skipping one to three stitches in the course direction, while the heel portion of the sock outer layer and the sock inner layer is knitted by flat knitting.

  In this case, the toe part of the outer sock layer and the inner sock layer is knitted by flat knitting sinker knitting with one or more front yarns in the same direction as other parts, and rubber yarn or covering yarn is used as the back yarn in the course direction. Alternatively, it may be knitted while skipping 1 to 3 stitches, or may be knitted flat.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a preferred embodiment of a sock according to the present invention. As shown in FIGS. 1 to 3, the sock has a double structure of the sock outer layer 10 and the sock inner layer 20, and the opening of the sock outer layer 10 and the opening of the sock inner layer 20 on the tip side are sewn together, and Both the sock outer layer 10 and the sock inner layer 20 are composed of a cuff part 30, a leg part 31, an instep part 32, a bottom part 33, and a heel part 34.

  In addition, the mouth part 30, leg part 31, instep part 32, and bottom part 33 of the sock outer layer 10 are knitted by pile knitting with a sinker of pile knitting using one or two No. 5 to No. 15 cotton yarns as surface yarns. At the same time, a single 90-th to 100-th rubber thread is used as the back thread, and it is knitted with one to three stitches.

  Further, the heel portion 34 of the sock outer layer 10 is knitted by plain knitting using one or two No. 5 to No. 15 cotton yarns as the front yarn.

  On the other hand, the cuff part 30, the leg part 31, the instep part 32, and the bottom part 33 of the sock inner layer 20 are knitted by pile knitting with a sinker on a pile knitting, using one or two 5th to 15th silk threads as surface yarns. At the same time, a single 90-th or 100-th rubber thread is used as the back thread, and it is knitted with one to three stitches.

  In addition, the heel part 34 of the sock inner layer 20 is knitted by flat knitting using one or two No. 5 or No. 15 silk threads as the front yarn.

  Here, the pile knitting sinker knitting in this example will be described. As shown in FIG. 4, the back yarn 41 in the pile knitting is knitted on the head 51 of the sinker 50 in the same manner as the front yarn 40. In this case, both the yarns 40 and 41 become front yarns, and the rubber yarn 44 takes the place of the back yarn.

  On the other hand, pile knitting will be described. The front yarn 40 is put on the head 51 of the sinker 50, and the back yarn 41 is knitted without being put, while the rubber yarn 44 is not put on the head of the sinker 50 and has an appropriate number of stitches in the course direction. Weaving while flying. Accordingly, the height of the pile 43 is determined by the height t in FIG.

  Accordingly, piles such as pile knitting cannot be performed by sinker knitting, but the stretch elasticity is small and the size is the same as pile knitting, but the elongation is twice or three times as large and the tightening is small.

  When manufacturing the sock of this example, a sock knitting machine is used, and the sock outer layer 10 and the sock inner layer 20 are knitted on a sinker on which a cuff part 30, a leg part 31, an instep part 32 and a bottom part 33 are pile knitted, and a heel part 35. Knit into a single cylinder so as to be flat knitted. The obtained tubular knitted body is folded back into two and the open portions at the tips of the sock outer layer 10 and the sock inner layer 20 are simultaneously stitched together to obtain the sock of this example.

  In the socks of this example, the toes, insteps, soles and arches were projected from the tip of the socks, so the toes were completely free and the feeling of pressure felt by sick socks and elderly people with sensitive skin sensations. It can be surely solved.

  In addition, if the toe of the sock is closed, it is very difficult for a person with a broken toe to wear due to treatment plaster, etc., but both ends of the sock are open, so there is plaster on the toe. But you can wear it lightly.

  In the sock of this example, the sock has a double structure of the outer layer 10 and the inner layer 20, and the cuff part 30, the leg part 31, the instep part 32 and the bottom part 33 are pile knitted sinker knitting. It is possible to obtain a large stretch and a moderate tightening force, which are characteristics of the above, and when wearing socks, a comfortable wearing feeling that softly covers the feet and legs can be obtained.

  Moreover, it is possible to reliably prevent the sock from slipping down with an appropriate tightening force, and it is not necessary to increase the tightening force of the cuff part 30 by knitting rubber thread into the cuff part 30, thereby eliminating the unpleasant biting feeling of the sock cuff. .

  Also, because of the large stretch characteristics of pile knitting sinker knitting, the entire sock stretches with a small force, so it can be easily worn by elderly and sick people with weak limb muscles, and the sock can be easily removed when taking off. You can take it off.

  Further, since flat knitting is adopted for the heel part 34, the deviation between the outer sock layer 10 and the inner sock layer 20 due to pile knitting sinker knitting can be prevented by the characteristics of the flat knitting, and the heel has wrinkles. Therefore, it can prevent taking off.

  Further, since the knitting yarns 40 and 41 of the sock outer layer 10 are cotton yarns and the knitting yarns 40 and 41 of the sock inner layer 20 are silk yarns, the sock outer layer 10 is excellent in moisture absorption by the cotton yarns, and the sock inner layer 20 is excellent in the silk yarns. Exhibits moisture absorption and heat absorption. As a result, for example, in summer, when the foot sweats, the silk thread quickly absorbs sweat, and the moisture of the silk thread is quickly absorbed by the cotton thread and dissipated to the surroundings.

  Further, the sock of this example has a double structure, and an air insulation layer is formed between the outer sock layer 10 and the sock inner layer 20 as shown in FIG. Even if it tries to permeate the sock, it is blocked between the sock inner and outer layers 10, 20, so that the cool air does not reach the feet and is warm to wear.

  FIG. 5 shows a second embodiment, and the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. In this example, the size of the instep portion 32 and the bottom portion 33 is increased so that more than half of the arch is covered with socks.

  FIG. 6 shows a third embodiment, and the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. In this example, the dimensions of the instep portion 32 and the bottom portion 33 are made longer than those in the second embodiment so that only the toes protrude from the socks.

  FIG. 7 shows a fourth embodiment, and the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. In this example, the leg portion 31 is made shorter than those in the first to third embodiments so that the portion just above the ankle is covered with socks.

  FIG. 8 shows a fifth embodiment, and the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. In this example, the leg portion 31 is made longer than in the first to third embodiments so that it is covered with socks up to just below the knee, or just above the knee.

  In the above example, pile knitting sinker riding knitting is adopted, but instead, flat knitting sinker riding knitting shown in FIG. 9 may be adopted. The flat knitting sinker knitting is a method of knitting the back yarn 71 in the flat knitting on the head 61 of the sinker 60 in the same manner as the front yarn 70 as shown in FIG. In this case, both the yarns 70 and 71 are front yarns, and the rubber yarn 73 is substituted for the back yarn.

  Accordingly, the flat knitting sinker knitting has a knitting structure similar to the pile knitting sinker knitting.

  FIG. 10 shows a fifth embodiment. The sock of the present example has a substantially square shape including a toe part 35, an instep part 32, a bottom part 33, a heel part 34, a leg part 31, and a cuff part 30, and is knitted into a continuous cylinder and folded back. The sock outer layer 10 and the sock inner layer 20 are configured in a double structure.

  The toe part 35, the instep part 32, the leg part 31, and the cuff part 30 of the sock outer layer 10 and the sock inner layer 20 use one or two No. 5 to No. 15 cotton yarns as surface yarns, and are knitted on a flat knitted sinker. And knitted with one to three stitches using a single 90-th to 100-th rubber thread as the back thread.

  Further, the heel portion 34 of the sock outer layer 10 and the sock inner layer 20 is knitted by plain knitting using one or two No. 5 to No. 15 cotton yarns as the front yarn. Further, the toe portions 35 of the sock outer layer 10 and the sock inner layer 20 are sewn into a bag shape.
