Description

  The present invention relates to a foot cover used as an inner sock or a room sock, and more particularly to a foot cover that can be manufactured without incurring high costs and is difficult to remove during walking.

  When women wear pumps or sneakers in the summer, wearing stockings can cause discomfort due to sweat or stuffiness, while wearing pumps etc. with bare feet should avoid the uncomfortable feeling caused by materials such as pumps directly touching the skin of the foot. I can't.

  Then, the shallow ship-shaped foot cover which consists of a toe part, a sole part, and a buttocks part is proposed (patent document 1). The foot cover described in Patent Document 1 is made of a single-cut fabric consisting of a sole portion, a side portion, and a heel portion, and is sewn so as to eliminate the joint of the sole portion to obtain an excellent wearing feeling. However, since the single cut fabric is manufactured and then sewn, the manufacturing operation is complicated.

  On the other hand, a non-sewn foot cover has been proposed in which a tubular knitted fabric is knitted by warp knitting and formed into a shallow ship shape using this fabric (Patent Document 2). However, since the warp knitted fabric was processed into a shallow ship shape, it was difficult for the buttock of the foot cover to fit perfectly on the heel of the foot, and it was easy to remove the buttock during walking.

  On the other hand, it has been proposed to provide a slip stopper on the heel part of the foot cover knitted by a sock knitting machine or the like (Patent Document 3, Patent Document 4, Patent Document 5).

  On the other hand, it has been proposed to use a circular knitting machine to knit the heel part of the foot cover into a three-dimensional shape corresponding to the heel of the foot or to adjust the elastic elasticity (Patent Document 6, Patent Document 7, Patent Document). 8).

JP 2008-297652 A JP 2004-124341 A Japanese Utility Model Publication No. 06-51207 JP 09-59804 A JP 11-335905 A Japanese Patent No. 3805729 JP 2004-11081 A JP 2008-261079 A

  However, in the foot covers described in Patent Documents 4 and 5, since the skin of the heel of the foot is rubbed by the slippage of the heel, there is a sense of incongruity.

  On the other hand, in the foot covers described in Patent Documents 6 to 8, it is difficult to take off the heel part by knitting the heel part into a three-dimensional shape corresponding to the heel of the foot or adjusting the elastic elasticity. Although there is little discomfort, there is a problem in that the production cost is higher than when a sock knitting machine is used because it is knitted with a circular knitting machine using a complicated program.

  In view of such problems, an object of the present invention is to provide a foot cover that can be manufactured without incurring high costs and that makes it difficult to remove the buttocks during walking.

  Therefore, the foot cover according to the present invention is knitted with knitting yarn or knitting yarn and elastic yarn, has a shallow ship shape composed of a toe portion, a sole portion and a heel portion, and a mouthpiece corresponding to the upper portion of the foot. In the foot cover in which the portion is formed, the heel portion has the same three-dimensional shape as the three-dimensional shape of the knitted socks.

  The feature of the present invention is that the heel portion of the foot cover is formed in the same three-dimensional shape as the sock toe portion.

  The inventors of the present invention made various foot cover prototypes and confirmed their wearing feeling and fit, and manufactured the foot cover's heel part in the same three-dimensional shape as the toe part of the same size or slightly larger socks Then, when the foot cover is worn, the portion of the heel of the foot cover that is close to the bottom of the foot hardly extends or slightly expands according to the shape of the heel of the foot. Because the part close to the ankle is lifted in the vertical direction by the heel part of the foot, the closer it is to the ankle, the larger it extends in the lateral direction (the direction from the heel part toward the toe part). As a result, the heel part of the foot cover is close to the ankle The heel part of the foot is wrapped with a large elastic elasticity, so the foot cover can be worn with an excellent fit, and the heel part of the foot cover can be removed even if the heel is raised or lowered during walking. One in which it was confirmed that there was no.

  Moreover, since the heel part, the upper part and / or the leg part of the sock may be cut and sewn, and the mouth part may be formed on the upper part of the sock, a circular knitting machine is used like the foot covers described in Patent Documents 6 to 8. It is not necessary to knitting a three-dimensional foot cover or adjusting a stretch elasticity by a complicated program, and there is no increase in manufacturing cost.

  For example, it is possible to manufacture a foot cover that is difficult to remove the heel part using socks as a material. That is, the sock toe portion constitutes the heel portion of the foot cover, the sock bottom portion constitutes the sole portion of the foot cover, the mouth portion is opened in the sock upper portion, and the edge portion having stretch elasticity is provided on the periphery of the mouth portion. On the other hand, the toe portion can be formed by cutting or sewing the sock heel portion.

  For the cuff part, an opening having a size and shape suitable for the foot cover may be formed.For example, a cuff part, for example, an elliptical cuff part, is formed from the vicinity of the sewn portion of the toe part opening to the sock upper part during sock knitting. The edge part which has elastic elasticity can be formed by cutting and folding back the seam of the cuff part along the rubber thread or elastic thread, or folding back and stitching with the rubber thread or elastic thread.

  Although the cut portion of the sock heel may be sewn with Rosso, it is preferable to sew the cut portion of the sock heel by linking in view of the merchandise (appearance) of the foot cover.

  Here, the socks are preferably knitted with a sock knitting machine in terms of cost, but no special socks are necessary for the production of the foot cover in the present invention, and socks knitted with a single cylinder or double cylinder type circular knitting machine. There may be. The size of the socks is preferably the same size as the foot cover or a slightly larger size. For example, in the case of a foot cover of 24 cm, it is preferable to manufacture using socks of 24 cm to 26 cm in consideration of moderate stretchability of the foot cover.

  Further, the method of knitting socks is not particularly limited, and flat knitting, mesh knitting, pile knitting, or a combination of these can be employed.

  The material of the knitting yarn is not particularly limited, and is used for socks such as cotton yarn, cotton acrylic blended yarn, wool yarn, wool acrylic blended yarn, silk yarn, silk acrylic blended yarn, hemp yarn, hemp acrylic blended yarn, nylon yarn, etc. Knitting yarn can be used. As the elastic yarn, nylon yarn, polyester yarn, polyurethane covered yarn, and core yarn can be used.

  In addition, the manufacturing method of the foot cover according to the present invention provides a toe portion of a sock knitted with knitting yarn or knitting yarn and elastic yarn in manufacturing a foot cover knitted with knitting yarn or knitting yarn and elastic yarn. Cutting the sock heel part, the sock upper part and / or the sock leg part at a position of a predetermined length with respect to the tip of the shoe, and sewing the cut part from the back side, and the vicinity of the sewing part of the toe part opening of the sock Forming a cuff portion toward the cut and sewn portion and forming an edge portion having elastic elasticity on the periphery of the cuff portion.

  Furthermore, the manufacturing method of the foot cover according to the present invention provides a toe portion of a sock knitted with knitting yarn or knitting yarn and elastic yarn in manufacturing a foot cover knitted with knitting yarn or knitting yarn and elastic yarn. Cutting the cuff part from the vicinity of the sewing portion of the opening to the sock back part and forming an edge having elastic elasticity on the periphery of the cuff part, and at a position of a predetermined length with reference to the tip of the sock toe part Cutting the sock heel part, the sock upper part and / or the sock leg part, and sewing the cut part from the back side.

  The foot cover obtained by either cutting or sewing cutting of the sock heel part and processing of the cuff part is the same.

  The sock heel is cut in a flat arc shape, for example, corresponding to the flat shape of the toe toe, but may be cut linearly and sewn in an arc shape. The socks may be folded and cut flat, and the socks may be turned inside out. Alternatively, the socks may be turned and turned flat and cut. The reason for turning inside out is that the cut portion is sewn from the back side.

  After cutting the sock heel, the cut portion is sewn from the back side by linking or Rosso. However, the sock heel portion may be sewn from the back side by an over-sewing machine, and then cut along the sewing location.

It is a schematic perspective view which shows the said embodiment. It is a side view which shows the sock used for manufacture in the said embodiment. It is a figure which shows the state which cuts and processes the said sock folded inside out flat. It is a top view which shows the foot cover manufactured in the said embodiment. It is a side view which shows one example of the size of the foot cover manufactured in the said embodiment.

  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 foot cover according to the present invention. The foot cover 10 has a shallow ship shape including a toe portion 11, a sole portion 12 and a heel portion 13, and an oval mouth portion 14 is formed at a portion corresponding to the ankle and instep.

  The toe portion 11 of the foot cover 10 is configured by cutting and sewing the heel portion 24, the upper portion 22 and / or the leg portion 25 of the material sock 20, and the sole 12 of the foot cover 10 is configured by the bottom portion 23 of the material sock 20. The cuff portion 24 is cut into the instep portion 22 of the material sock 20, while the heel portion 13 of the foot cover 10 is composed of the toe portion 21 of the material sock 20, and the three-dimensional shape of the toe portion 21 of the material sock 20. It has the same three-dimensional shape as the shape. In the figure, 15 is a sock toe opening sewing location, 16 is a gore line, and 17 is a cut sewing location.

  When manufacturing the foot cover 10, the material socks 20 are manufactured. The material sock 20 is knitted into a flat knitting structure with a sock knitting machine using a sock knitting machine, but is knitted by a single cylinder or a double cylinder circular knitting machine by mesh knitting, pile knitting, or a combination of mesh knitting, pile knitting, and flat knitting. You can also.

  For example, cotton yarn can be used as the knitting yarn, and polyurethane-coated polyester yarn can be used as the elastic yarn. When knitting with a sock knitting machine, it is knitted in a cylindrical shape from the mouth of the material sock 20 toward the tip side of the leg part 25, the heel part 24, the instep part 22 and the sole part 23, and the toe part 21 leaves an opening. Organized.

  When the material sock 20 is knitted in this way, it is removed from the sock knitting machine, and the opening of the toe portion 21 is sewn by linking from the back side. In FIG. 3, 26 is a sewing location. In place of linking, sewing may be performed with Rosso.

  When the material socks 20 are obtained, as shown in FIG. 4, the material socks 20 are turned over, folded flat, and cut into a circular arc at a predetermined length with respect to the tip of the toe 21. Depending on the size of the material sock 20, the cut portion 30 is one of the sock upper part 22 (including the sock bottom part 23), the sock heel part 24, and the sock leg part 25. The cut portion 30 is sewn by linking and constitutes the toe portion 11 of the foot cover 10.

  Considering the feeling of wearing and fit (hardness to remove) of the heel part 13 of the foot cover 10, the material sock 20 is preferably the same size as the foot cover 10 and a slightly larger size. For example, when the foot cover 10 is 24 cm, the material sock 20 is 24 cm to 26 cm, and when the foot cover 10 is 23 cm, the material sock 20 is preferably about 23 cm to 24.5 cm. Can also be used.

  Further, the opening 31 is cut into an elliptical shape in the vicinity of the opening sewing portion 26 of the toe portion 21 of the sock 20, for example, by 1 to 2 cm from the position on the sock upper portion 22 side to the upper portion 22 of the sock 20. Are folded and stitched along a rubber thread or elastic thread with a width of 5 mm to form an edge part 14A having elastic elasticity, so that a cuff part 14 and a heel part 13 of the foot cover 10 are obtained. Can be manufactured.

  As described above, since the heel part 13 of the foot cover 10 is formed in the same three-dimensional shape as the toe part 21 of the sock 20, the foot has a large elastic elasticity as the heel part 12 of the foot cover 10 becomes closer to the ankle. The heel of the foot cover 10 is excellent in fit, and even if the heel is moved up and down during walking, the heel 13 of the foot cover 10 is hardly removed.

  Moreover, since the heel part 24, the upper part 22 and / or the leg part 25 of the material sock 20 are cut and sewn, and the cuff part 14 may be cut on the upper part 22 of the material sock 20, Patent Documents 6 to 8 There is no need to knitting a three-dimensional foot cover or adjusting a stretch elasticity by a complicated program using a circular knitting machine as in the described foot cover, and this does not lead to high manufacturing costs. As a result, it is possible to obtain an inexpensive foot cover that fits perfectly on the foot and is difficult to remove the buttock.

  The characteristics of the obtained foot cover 10 were obtained. In FIG. 6, the actual size A is 20.0 cm, the total length B is 4.5 cm, the rubber band length C is 0.5 cm, and the rubber band width D is 13.5 cm. The toe width E was 8.0 cm, the bottom width F was 6.0 cm, and the toe length G was 4.5 cm. In terms of extension, the actual size A is 36.0 cm, the total height B is 8.0 cm, the mouth rubber width D is 26.0 cm, and the toe width E is 14.0 cm, so that an appropriate elastic elastic foot cover can be obtained. confirmed.

  In the above, it was cut into an arc shape and sewed, but it may be cut into a linear shape and sewed into a linear shape, or may be sewn and cut into an arc shape, or cut into a linear shape and made into an arc shape or a linear shape. You may make it sew.
