Description

  The present invention can be used for underwater walking in the pool, exercise centered on barefoot walking, aquabics, etc., and also for indoor walking where elderly people and children can go up and down stairs that are slippery corridors and stairs. The present invention relates to a sock for walking and a manufacturing method thereof.

  Recently, barefoot walking such as exercise for health management and underwater walking for rehabilitation has been attracting attention, but in the case of completely bare feet, the soles do not touch the bottom of the pool reliably and are idle There was a problem that it could be dangerous because it could fall or fall, and the original effect could not be achieved.

For such problems, conventionally, shoes for underwater walking and poolside walking as described in Patent Documents 1 and 2, for example, have been proposed, and further, for underwater walking as described in Patent Documents 3 and 4 Wearing equipment has also been proposed.

  However, the shoe-like thing covering the whole ankle has a problem that the feeling of bare feet is not sufficient, the sole does not get used to the pool bottom, and it does not wipe off the sense of incongruity such as getting wet while wearing shoes. In the case of a wearing tool having a large opening, rubber or the like must be used as a material, so that there is a problem that water enters between the wearing tool and the ankle and accumulates without leaving, leaving an uncomfortable feeling.

  In addition, the fit between the ankle and wearing equipment is also a problem, and if materials such as rubber are used that are not compatible with the skin, a foreign body feeling is added, and even if it is too tight or too loose, it will impair the sense of satisfaction as barefoot exercise Become. On the other hand, walking on the pool side which is wet and slippery, and the exposed part of the sole for satisfying the feeling of bare feet and the anti-slip which touches the sole to the bottom of the pool and reliably catches are also problems.

  In addition, when you get out of the water, wearing wet equipment will cause your feet to cool down, and when you move from underwater walking to swimming, you will have a feeling of strangeness when wearing shoes and wearing equipment. Because there is a problem that can not be enjoyed enough, each time there was a trouble that had to put on and take off the braces one by one.

  On the other hand, the human ankle has a three-dimensional shape formed by a chain of delicate curved surfaces, and it is difficult to form a sock body 1 that fits without a sense of incongruity when worn by sewing with a flat drawing. The socks are knitted in a three-dimensional manner from the beginning by calculating and adjusting the number of eyes.

  However, when cutting open holes that partially open the upper and heel of socks that are knitted in three dimensions, an accurate shape standard should be set unless it is based on a flat production drawing. I can't. Further, if the open hole is cut off unnecessarily, fraying occurs at the edge of the open hole, which makes it difficult to handle the edge and causes the open hole to be distorted when worn.

  The present invention is intended to address the above-described problems, and the main body is constituted by a material that fits without a sense of incongruity when worn, such as a knitted fabric of synthetic fibers such as nylon and polyester. In particular, if spandex (polyurethane elastic fiber) is used as a synthetic fiber, it has a tensile strength several times that of rubber, stretches better than rubber, has a low specific gravity, and is light and stretchable due to a light knitted fabric. Quick drying when it rises can also be obtained.

  In addition, by providing finger holes to separate and expose the toes at the toe part, the grip strength during landing is secured, and a non-slip cushion sheet is set on the toe side sole ground to strengthen the kicking foot during action It is also possible to handle walking on a poolside that is slippery.

  Further, the non-slip sheet is configured by setting a non-slip structure with small holes or irregularities on the grounding surface of an elastic resin material such as ABS-based elastic resin or rubber, and between the toe-side foot sole and the non-slip sheet. A cushioning sheet made of foamed material such as urethane foam with closed cells is used to form a non-slip cushion sheet, which absorbs foot shock during kicking foot movement and slips against the floor surface when loaded The adhesion area of the stop structure is increased.

  In addition, the non-slip cushion sheet is made of urethane foam material with closed cells. Urethane foam has cushioning properties and adsorbability, but if it is open cells, it absorbs water, so when it rises from the water, it will exude water and become uncomfortable and difficult to dry. Loss and quick drying was improved.

  In addition, the back of the foot and the back of the foot excluding the toe-side sole 21 are formed so as to enhance the feeling of bare feet, and the fabric area is reduced so that it can be carried compactly. Although it was possible to simplify, the peripheral edge of the insertion opening into which the foot is inserted is colored or trimmed so that it can be distinguished from other open parts for convenience in use because it is complicated in shape.

  Embodiments of the present invention will be described below with reference to the drawings. 1 is the body of a barefoot walking sock, which is made of spandex (polyurethane elastic fiber), polyester or nylon, or a knitted fabric made of a blend thereof, and a toe 5 knitted as a sock with five fingers in a glove shape. A finger hole 2a is formed to separate and expose the tip toe of the finger part. The peripheral edge of the foot insertion opening 4 is colored or trimmed so that it can be distinguished from other open parts.

  The upper part of the foot is notched with an instep opening part 3 and an insertion opening part 4 for inserting the foot, and the sole is formed with a sole opening part that largely opens the heel part along the heel from the arch. And the toe part 2 provided with finger holes 2a for projecting and exposing each finger, the landing surface 21 constituting the toe side foot bottom surface, and the tension part 22 applied to the upper part of the heel as the edge of the insertion opening 4 As an ankle has been included.

  A cushion sheet 61 made of an elastic foam material made up of closed cells is set on the toe side sole ground surface 21, and its upper surface is covered and fixed with a non-slip sheet 6 made of ABS elastic resin. The anti-slip sheet 6 is provided with a non-slip structure 62 formed of small holes and irregularities on the ground contact surface.

  The production of the socks for walking with bare feet according to the present invention is carried out by attaching finger socks three-dimensionally knitted with synthetic fibers to an ankle-shaped flat paper pattern, and first, for the upper side of the same shape as the above-mentioned paper pattern showing the opening cut-off index. The crease transparent mount 11 is superposed to display an indicator on the indexing socks, and turned over, the sole scribe transparent mount 12 is superposed to display the indicator on the index socks.

  Indices are displayed by entering the cut line and point display of the instep opening 3 of e to h of the transparent mount 11 for instep side marking shown in FIG. 4, and the inscription on the sole from the upper side to the sole side. The cut lines a to d and the point display of the sole opening 5 are entered by the transparent mount 12, and the overlock sewing machine performs cutting and sewing at the same time based on the index. It should be noted that the points a to d of the instep side ruled transparent mount 11 coincide with the points a to d of the sole ruled transparent mount 12 as the same point.

  The main body 1 configured in this way is mounted on a solid ankle shape, a cushion sheet 61 is set on the landing surface 21, and a non-slip sheet 6 is placed on and covered, and fixed and processed to complete the product. .

  Also, as another example of the non-slip cushion sheet, a cushion material formed of foam material is laid on the toe-side contact portion inside the toe side landing of the sock body, and the anti-slip sheet is set on the outer landing socks. The body fabric is sandwiched and a non-slip cushion sheet is integrally formed by thermocompression bonding.

  The sock body 1 is attached to the foot by inserting the foot into the insertion opening 4 of the sock body 1 configured as described above, fitting the toes into the finger holes of the toe part 2 and hanging the tension part 22 on the upper part of the heel. It is in close contact and satisfies a moderate tension and bare foot feeling, and can swim while walking on the poolside while wearing the sock body 1.

  The socks for barefoot walking according to the present invention are not only used for exercises such as underwater walking, but also for ensuring the safety of indoor walks where people with disabilities, pregnant women, elderly people, children, etc. slip up and down stairs. The range of use is extremely wide.

  Since the present invention is configured as described above, the toe and heel are opened and the floor of the pool is securely captured by a non-slip, while holding a disabled person, a pregnant woman, an elderly person, a child, or an injury. Sports athletes can satisfy their barefoot feeling and exercise safely and rehabilitate.

FIG. 3 is a side view of a footwear ankle showing an embodiment of a footwear sock for barefoot walking according to the present invention and showing a state of wearing the sock for walking barefoot according to the present invention. Similarly, it is a top view of the back side of a wearable ankle. Similarly, it is a top view of the sole side of a footwear ankle. Similarly, a cushioning material was set on the inside of the sock, and a non-slip sheet was placed between the sock fabric and a non-slip cushion sheet was constructed by thermocompression. It is the side view which notched the said fabric part of the socks for barefoot walking. In the same way, the product surface scribing is displayed on the index socks by superimposing transparent paper for scoring the same shape as the paper that is attached to the ankle-shaped flat paper and displaying the open cut-off indicator for cutting the open part. It is a front-and-back corresponding explanatory view of the cut line which shows the setting state of the cut line in parallel with the transparent mount for paper and the transparent paper for marking on the back of the product.
