Description

  The present invention relates to a stocking to be worn on a person's leg, and more particularly to a stocking that reduces the occurrence of strong pressure applied locally by a heel or the like.

  A conventional stocking will be described. FIG. 3 is a side view showing a conventional stocking. The conventional stocking 300 is configured to cover a portion from the tip of the foot to the calf, and includes a foot insertion opening 311 for inserting the foot on the upper end side. Also, a calf covering portion 302 that covers the calf, an ankle covering portion 303 that covers the ankle, an instep covering portion 304 that covers the instep, a bent covering portion 305 that covers the bent portion of the foot between the ankle and the instep, A foot covering part 306 covering the foot, a heel covering part 307 covering the heel of the foot, and a foot covering part 308 covering the sole of the foot.

  The calf covering portion 302, the ankle covering portion 303, the instep covering portion 304, the bending covering portion 305, the toe covering portion 306, the heel covering portion 307, and the sole covering portion 308 are formed by forming the knitted fabric body 409 shown in FIG. Used in shape. In the knitted fabric body 409, a stitch 493 is formed by knitting the base yarn 491, and a course stitch row 494 is formed by forming the stitch 493 side by side in the course direction (Y-Y direction in FIG. 4). Then, the course stitch row 494 forms a plurality of rows in the wale direction (XX direction in FIG. 4), thereby forming a course stitch row group 490 consisting of groups.

  The elastic yarn 495 is inserted into the stitch 493 for each course stitch row 494, and a plurality of rows of elastic yarns 495 are formed at a predetermined distance in the wale direction. A knitted fabric body 409 is formed by the course stitch row 494 and the rows of the plurality of elastic yarns 495 formed as described above.

  The ratio of the number of rows of elastic yarns 495 to the number of rows in the course direction of the course stitch row 494 of the calf covering portion 302 and the ankle covering portion 303 is substantially equal. On the other hand, the ratio of the number of rows of elastic yarns 495 to the number of rows in the course direction of the course stitch row 494 of the upper covering portion 304, the bending covering portion 305, the toe covering portion 306, the heel covering portion 307, and the sole covering portion 308 Is about half. Thus, due to the difference in the proportion of the elastic yarn 495, the upper covering portion 304, the bent covering portion 305, the toe covering portion 306, the heel covering portion 307, and the sole covering portion as compared with the calf covering portion 302 and the ankle covering portion 303. In 308, the knitted fabric elastic force is weakened.

  In the stocking 300 having the above-described configuration, the calf covering portion 302 and the ankle covering portion 303 strongly apply pressure (pressure) applied to the skin, and the upper covering portion 304, the bent covering portion 305, the toe covering portion 306, and the heel covering portion. The pressure applied to the skin can be reduced at 307 and the sole covering portion 308. Then, by wearing the stocking 300 having the above-described configuration, the bent covering portion 305 is less likely to become a heel-like shape, and the heel is difficult to bite into the bent portion of the foot, and from the ankle covering portion 303 to the calf covering portion 302. Blood circulation can be improved (see, for example, Patent Document 1).

JP 2011-94250 A

  However, in the conventional stockings, the occurrence of wrinkles cannot be sufficiently suppressed even with stockings in which the pressure applied to the bent covering portion 305 is lower than that of the calf covering portion 302 and the ankle covering portion 303. There was a problem that a strong pressure was applied and a pressure wound was generated. In addition, there is a problem that local overpressure may be applied even in a place where wrinkles are unlikely to occur, such as the upper covering portion 304, and a pressure wound is generated. The present invention provides a stocking that reduces the occurrence of wrinkles and over-compression and can enhance the effect of preventing pressure wounds compared to conventional stockings.

In order to solve the conventional problems, the stocking of the present invention has the following configuration.
A main body, an opening on the upper end side of the main body, an opening for inserting a foot, a toe covering portion that covers the toe, and a bent covering portion facing a bent portion of the foot between the ankle and the instep; At least the first metatarsal tip and / or the fifth metatarsal tip, and the first knitted fabric main body constituting the main body is knitted with a base yarn. The first course stitch row formed by arranging a plurality of stitches in the course direction is aligned with the first course stitch row group formed in a plurality of rows in the wale direction and the first course stitch row. A plurality of elastic yarns formed in a direction, and the second knitted fabric body constituting the bent covering portion includes a plurality of second stitches knitted by the base yarn in the course direction. The second course stitch row formed side by side is a second core formed with a plurality of rows in the wale direction. A plurality of elastic yarns formed in the wale direction so as to follow the second course stitch row, and the elongation in the wale direction is 250% or more. The third knitted fabric main body constituting the toe root portion is formed by arranging a plurality of third knitted stitches knitted with the base yarn in the course direction. , A third course stitch row group formed in a plurality of rows in the wale direction, and a plurality of rows of elastic yarns formed in the wale direction along the third course stitch rows. The elongation in the wale direction is 250% or more.

  The stocking of the present invention reduces the local pressure on the skin due to the generation of wrinkles when worn, and reduces the occurrence of local pressure on the skin even in areas where wrinkles are difficult to occur. Compared with, the preventive effect of pressure wounds can be enhanced.
