Description

  The present invention relates to pantyhose, tights, high socks, and other stockings that are worn over a foot portion of a foot (a portion from a toe portion to a heel).

Conventionally, with respect to stockings such as pantyhose, tights, high socks, etc., many documents are known for their production methods and products (for example, see Patent Documents 1 and 2).
Japanese Patent No. 3386309 JP 2001-316902 A

  In addition, it is possible to see a part of the leg portion in consideration of such clothing pressure and to make the leg portion feel comfortable. Many of these products have already been created, and many of those currently on the market have become so-called “comfort pressure design”. These are mainly designed to make the ankle the strongest while gradually weakening it from the lower leg to the thigh, and the wearing feeling is comfortable.

  However, in these known stockings, only those that take into account the clothing pressure of only the leg part (part from the ankle to the thigh) are seen, and the foot part is not considered, and the comfort of the foot part Lack of thinking.

  In view of such a situation, the present inventor studied in detail the clothing pressure in the foot part of the stocking from the viewpoint of comfort at the time of wearing, and led to the present invention.

  The present invention is intended to solve the above-described problems of the prior art, and it is an object of the present invention to provide a stocking that provides a comfortable wearing feeling by considering the clothing pressure distribution in the foot. is there.

1. As a result of intensive studies in order to solve the above problems, the present inventors have finally completed the present invention. That is, the present invention has the following configuration. Both clothing pressure applied to the distal end of the distal phalanx of the longest toe and the heel of the ribs are around the metatarsal region (on the toe side of the first and fifth metatarsals of the foot). A stocking characterized by being in a range of -3 kPa to +3 kPa with respect to the clothing pressure applied to the periphery of the direction connecting the tips.
2. The clothing pressure applied to the distal end of the distal phalanx of the longest toe and the heel of the rib is less than 6 kPa, and the circumference of the metatarsal (the first metatarsal and fifth metatarsal feet of the foot). 2. The stocking according to claim 1, wherein the clothing pressure applied to the periphery of the direction connecting the front ends is 3 kPa or more and the ankle portion is 1 ka or more.
3. The stitch density of each part of the stocking is 100 to 120 around the metatarsal bone region, 30 to 60 at the toe portion and the heel portion, and 30 to 120 at the ankle portion. 2 stockings.

  In the stockings according to the present invention, both of the clothing pressure applied to the distal phalanx tip of the longest toe and the heel of the rib are the first and fifth metatarsals around the metatarsal bone. By exhibiting a clothing pressure in the range of -3 kPa to +3 kPa with respect to the clothing pressure applied to the circumference of the direction connecting the tips of the toes of the foot, there is an advantage that a comfortable wearing feeling can be obtained. Furthermore, the clothes pressure of the ankle does not become too low, and the stocking prevents the ankle from becoming loose and uncomfortable.

  Hereinafter, the present invention will be described in detail.

  FIG. 2 shows the positions of the distal end of the distal phalanx, the ribs of the ribs, and the metatarsals. The skeleton is as shown in FIG. The first metatarsal bone, the fifth metatarsal bone, and the long axis direction are also shown in FIG. In the stocking of the present invention, both of the clothing pressure applied to the distal phalanx tip of the longest toe and the heel of the rib are the first metatarsal bone and the fifth metatarsal bone of the surrounding leg of the metatarsal bone. The pressure is about -3 kPa to +3 kPa with respect to the clothing pressure applied in the direction connecting the tips of the toes. If the clothing pressure is lower than -3 kPa, the knitted fabric of the stockings may be twisted or surpassed, which may cause wrinkles and make it unsightly or uncomfortable to wear. On the other hand, if it is higher than +3 kPa, the movement of the toes is hindered and it becomes uncomfortable and uncomfortable, and further, the tip of the toes is pushed by the stockings and the toes are bent, and the toe skeleton is in a natural state Not. Accordingly, a clothing pressure of -3 kPa to +3 kPa is preferable, but desirably, a force of opening the toes acts in the range of 0 kPa to +3 kPa, and an effect of keeping the foot skeleton normal can be exhibited.

  In the stocking of the present invention, both the clothing pressure applied to the distal phalanx tip of the longest toe and the heel of the rib is less than 6 kPa, and the first metatarsal and 5 is a stocking having a clothing pressure of 3 kPa or more and an ankle portion of 1 kPa or more. If both of the clothing pressure applied to the distal phalanx tip of the longest toe and the heel of the rib are 6 kPa or more, the tip of the toe is pushed by the stocking and the toe is bent, It is no longer natural. Therefore, it is appropriate to be less than 6 kPa, but less than 5 kPa is preferable because it does not place a burden on the foot skeleton. If the clothing pressure applied to the circumference of the circumference of the metatarsal bone is less than 3 kPa, the knitted fabric constituting the stockings is twisted. It is not preferable because it is wrinkled and unsightly and uncomfortable to wear. Therefore, 3 kPa or more is appropriate, but if it is 4 kPa or more, the force to open the toes acts, and the effect of keeping the foot skeleton normal can be exhibited. Furthermore, the ankle part needs to be 1 kPa or more. If it is less than 1 kPa, the wearer may feel uncomfortable and wrinkles may occur. When it is 1 kPa or more, there is a moderate feeling of squeezing and it feels comfortable, but when it is 2 kPa or more, the feeling of comfort is improved.

  The stockings of the present invention can be expected to open their toes when the metatarsal portion is tightened. This is considered a good medical direction. Further, by fixing the metatarsal portion, the first metatarsal bone and the fifth metatarsal bone are not opened, and an arch of the sole is easily formed, and as a result, correct walking is possible.

  If the clothing pressure is 6 kPa or more at the distal phalanx distal end of the long toe and the heel of the rib, the feeling of tightening becomes tight and the feeling of wearing becomes worse. Furthermore, there is a possibility that the toe skeleton in which fine bones are gathered will be deformed, and the metatarsal bone will be opened, resulting in hallux valgus and hallux valgus.

  From the above, it is desirable that the clothing pressure is small in the longitudinal direction of the foot, both in the feeling of wearing and in the foot skeleton, and that the clothing pressure is large in the circumferential direction of the foot, both in the feeling of wearing and in the foot skeleton. It is desirable.

  The stitch density of the present invention is represented by (1) × (2) by determining the number of stitches in the wale direction per inch (1) and the number of stitches in the course direction per inch (2). As the sample, an actual measurement value with a placement size is used. In addition, a measurement site | part grasps | measures and measures the part corresponded to the position when a monitor with a foot size of 23 cm is worn at the measurement position. Even if it is not a monitor, it may be worn on an M-size leg, and a measurement site may be marked, and then the stitch density at the placing dimension may be measured.

  The stitch density of the metatarsal bone portion needs to be 100 to 120. When it is 100 or less, the caulking in the circumference direction of the metatarsal part is weak, and a comfortable wearing feeling cannot be obtained. Moreover, the force which opens a toe and forms a normal foot skeleton is hard to act. When it is 200 or more, it is not appropriate because it becomes difficult to wear when worn. Desirably, if it is 110-120, a metatarsal bone can fully be tightened. The stitch density of the toe portion and the heel portion needs to be 30 to 60. When it is 30 or less, the knitted fabric is loose, which is not preferable in terms of appearance and wearing feeling. Moreover, when it is 60 or more, a force that bends a finger from the toe tip acts, which is not easy on the foot skeleton, and discomfort increases even when worn. Desirably, when it is 30 to 50, an excessive force is not applied to the toes, and the toes can be moved very naturally. The stitch density of the ankle part needs to be 30 to 120. If it is 30 or less, wrinkles are not easily formed on the appearance, and the feeling of wearing is not good. When it is 120 or more, the feeling of wearing is comfortable, but there is a problem that it is difficult to wear when wearing. Desirably, when it is 50 to 110, a moderate squealing feeling is generated and the user feels comfortable.

  For measuring the clothing pressure when wearing stockings, an air pack clothing pressure measuring device (model 13037-10) manufactured by AMI, which is a commercially available clothing pressure measuring device, was used. This device uses a bag-shaped pressure sensor called an air pack, encloses a certain amount of air in the pack, and reads the force for crushing the pack as clothing pressure. In accordance with the handling method of this device, a predetermined amount of air is sealed in an air pack, and the adjusted pack is affixed to the toes and buttocks of the human body to measure the clothing pressure when wearing stockings. is there. The measurement was performed using an air pack having an elongated shape of 8 mm × 28 mm so that the pressure was applied in the vertical direction even at a leg portion having a large curvature.

Next, the present invention will be specifically described using examples and comparative examples. The following method for producing stockings is not limited to the examples, and a known method may be adopted.
This can be realized by designing the pressure distribution in the foot region appropriately. Hereinafter, although an Example and a comparative example evaluated with the high socks type, it is the same also with pantyhose.

  For the stockings of Examples and Comparative Examples, the distal end of the distal phalanx of the longest toe, the clothing pressure applied at the heel of the rib, and the periphery of the metatarsal (first metatarsal and fifth metatarsal of the foot) Clothing pressure applied to the periphery of the direction of connecting the tips of the toes, and the clothing pressure at the ankle. Moreover, the wearing test was implemented with the following method.

  For clothing pressure measurement, an air pack type clothing pressure measuring device manufactured by AMI as described in the preceding paragraph was used. One monitor with a foot length of 23 cm, which has an oblique type (Egyptian type) toe with the longest thumb, and the shape of the foot part is the subject, the toe part of the tip of the thumb, the buttocks, and the metatarsal part, The clothing pressure at the ankle was measured by attaching an air pack sensor.

  In the wearing test, five female subjects having an oblique-type toe shape were worn once for 3 hours, and the feeling after wearing for 3 hours was answered about the good feeling of wearing the foot.
