Description

The present invention relates to a shoe insole in which a finger crotch partition wall such as an underground tab is formed in a shoe to improve motor functionality and prevent toe failure.

Conventionally, in a shoe for preventing or correcting hallux valgus, a soft insole for laying on the entire sole, a hard bottom substrate fixed to a toe portion of the soft insole, and the hard bottom substrate It consists of a protective substrate that is firmly fixed and stands almost vertically on the upper surface of the soft insole and enters between the first heel and the second heel. It is known that the user can relatively adjust the position of the protective substrate by cutting the soft insole according to the size of the shoe and the position of the heel by being sufficiently large in the foot width direction. ing. It is also disclosed that a part formed of a soft material is fitted so that pain does not occur even if a finger touches the protective plate. (Patent Document 1)

In the present invention, a protective substrate standing on a strong bottom substrate is provided, and pain is caused by relatively adjusting the position of the protective substrate according to the size of each person's shoes and the position of the thumb. The purpose is to be able to walk without any problems and to prevent and correct the hallux phalanx more effectively.
However, on the other hand, the insole of the present invention must prepare the soft material separately for the protective substrate, and the soft insole must be large in the foot width direction with respect to the shoe of the applicable size. There is a disadvantage that the material of the insole is lost and the cost is increased accordingly.

Further, as another prior art, a correction column body is vertically suspended at a position corresponding to the space between the first and second heels in the shoe, and is sandwiched between the heels having a substantially rounded rectangular cross section upward from the surface of the insole. There is a known shoe with a correction column of a hallux finger. Furthermore, it is disclosed that the correction column body may be formed as a hollow column by forming a hollow inside thereof. (Patent Document 2)

According to the present invention, it is possible to increase the blood circulation effect by stimulating the hallux phalanx in the same wearing state as normal shoes and the path stimulation of the first and second heels. Therefore, when sandwiched between fingers, the side wall of the corrective body is almost flat, so that only part of the surface of the finger can be touched. There was a tendency for dust to enter from the opening of the door and dirty inside the hollow.

Furthermore, in an insole having another conventional crotch partition, a slit having an attachment position adjustment margin is provided at a position corresponding to the crotch portion between the first and second heels of the foot, The crotch bulkhead formed integrally with the fixing member is protruded from the slit above the insole surface, and the fixing member is a material that has viscoelasticity and is difficult to slide, and the stepping portion from at least the toe of the insole back surface is, There is disclosed an insole that is covered with a cloth or a nonwoven fabric having a looped surface or a surface that has been subjected to brushing, shrinking or flocking, and in which the fixing member and the back of the insole are detachably fixed. Further, it is disclosed that a soft viscoelastic material is used as a material for the crotch partition wall. (Patent Document 3)

The present invention can easily adjust the attachment position of the crotch partition at the tip of the insole to the position that suits you, and it can be removed when washing or unnecessary, while it is a slit for installation adjustment on the insole In addition, since the crotch partition is fixed with a loop-shaped cloth, there is a discomfort during use, and the feeling of wearing is not satisfied because the tension is not applied.

In the conventional invention, what is provided with a soft protective body to relieve the friction between the corrective body (crotch septum) and the toes during exercise is disclosed, but the frictional heat generated by them is actively dissipated. There was nothing to cool with. In addition, the conventional orthodontic body (crotch septum) does not satisfy the grip feeling because it only partially adheres along the toe surface, and cannot exert the tension force more effectively. Furthermore, there is a concern that the foot may slip forward in the shoe and the crotch portion of the foot may hit the corrector (crotch septum), resulting in poor wearing feeling.

In the insole of the present invention, by providing a space that opens downward in the inside of the crotch partition wall, both side walls of the crotch partition wall are recessed inward of the space to conform to the shape of the finger. The area is increased, the gripping feeling and the tension force are effectively improved, and frictional heat generated by sliding contact between the partition wall and the toes is conducted from the partition wall to the inner space, and outside air is opened to the space. Because it goes in and out and is cooled by ventilation, it tries to prevent the pain disorder due to finger rubbing.

The insole of the present invention is provided with a non-slipable fiber on the first and fifth heels of the sole and along the concave portion of the sole main body, and further on the upper surface of the heel portion. In order to prevent slipping of the foot, the overall tension force is effectively promoted. In addition, the present invention allows the crotch partition wall member to be removed from the insole so that it can be kept clean by replacing or cleaning with a new one, and the toe width is only the space width of the crotch partition wall By narrowing, the foot width direction of the foot can be finely adjusted.

A shoe insole of the present invention is a shoe insole having a finger crotch partition wall, a cushioning insole body in which a mounting hole is formed at a position corresponding to between the first and second heels of the foot, and a plate A partition wall provided with a space opened downward in a wall that is integrally formed on a cylindrical base and erected in the vertical direction, and includes a finger crotch partition wall member made of an elastic material, the finger The insole body and the finger crotch partition wall member were made detachable by inserting the crotch partition wall member into the mounting hole and projecting and fitting the partition wall from the upper surface of the insole.

Thereby, when the shoe insole of the present invention is mounted on the shoe and walks and runs, the finger crotch partition wall is formed of an elastic material and the space is closed by the front and rear side edges and the upper edge Therefore, since the vicinity of the center of both side walls sandwiched between fingers is recessed into the space and closely adhered along the side surfaces of the first and second fingers, the sandwiching force and the tension force are effectively improved. The

Further, the shoe insole of the present invention is configured such that frictional heat due to sliding contact between the finger in use and the side wall of the finger crotch partition wall is conducted and dissipated through the partition wall to the space, and the opening below the partition wall space. Since the outside air enters and is ventilated and cooled, the occurrence of scratching and blistering of fingers is prevented.

The finger crotch partition wall is made of a synthetic resin such as polyvinyl chloride or polypropylene or a synthetic rubber such as SBR, BR, or silicone rubber as an elastic material. Also, the hardness of the elastic material is set to 30 to 70 degrees (JIS-A). If the hardness is 30 degrees or less, it is too soft and the tension force is lowered. If it is 70 or more, it is too hard and fits. There is a disagreeable feeling.

The partition wall has a width in which the side wall in the longitudinal direction covers the side surface of the intercostal joint of the first and second ribs, and the outer corner of the partition wall is rounded to form a corner. A shoe insole according to claim 1 is provided.

Thereby, the height of the space portion of the partition wall of the finger crotch partition wall member is substantially the same as the height of the first heel, and the longitudinal width corresponds to the joint portion of the proximal phalanx and the distal phalanx. Therefore, since the side wall of the partition wall is indented inward of the space so as to cover the entire side portion of the intercostal joint of the first heel, it can be securely sandwiched. Further, the outer corners of the partition wall are provided with rounded corners, so that the toes can be easily inserted into the partition wall of the toes without feeling uncomfortable.

The insole body has a ridge formed on the upper surface of the insole along the recess between the first to fifth heels of the sole and the sole body. The insole described was used.

As a result, the insole body has a ridge on the upper surface of the insole along the recesses between the first to fifth heels of the sole and the sole main body, so that the first heel to the fifth heel of the sole more With this, it is possible to grip the ridge body, and the tension force is further improved.

The insole main body has a surface of the buttock that is overlaid with a material that is not slippery, and a front half that is forward of the buttock is overlaid with a material that is more slippery than the lining of the buttock. The insole of the shoe according to any one of 1 to 3.

Specifically, the material for the upper part of the buttock is a fuzzy material of synthetic fiber such as polyester fiber, acrylic fiber, polyamide fiber, polyethylene fiber, polyvinyl chloride fiber, etc. As the material that is more slippery than the part, mesh-like fibers such as the same synthetic fibers as described above, or fibers having a rough interval between the warp and the weft are used.

The front half of the surface of the insole body is made of a material that is more slippery than the lining of the buttock. Slip of the foot forward is prevented, and the crotch portion between the first heel and the second heel is prevented from hitting the partition wall.

The shoe insole according to the present invention includes a partition wall provided with a space opened below a substantially rectangular parallelepiped protrusion that is erected substantially vertically between a first heel and a second heel on a plate-like base. Since the center of both side walls is recessed into the space along the finger side surface, the contact area is in close contact with the maximum, and the pinching force of the finger can be effectively improved. In addition, the insole of the present invention can radiate and cool the frictional heat caused by the sliding contact between the finger and the side wall of the partition wall through the space of the partition wall, and can prevent the finger from being obstructed. .

And, by forming the ridges on the upper surface of the insole along the recesses between the first to fifth heels of the sole and the sole body, the gripping force of the toes is further promoted, and the kicking action is performed. It can be improved effectively. Furthermore, the insole of the present invention is provided with a material that is difficult to slip on the upper surface of the heel part, and this prevents slipping forward of the foot in the shoe. There is an effect that the feeling of wearing is improved without hitting the finger crotch partition wall.
