Abstract

An insole structure in which a heel supporting protrusion is protruding from the front edge of the pad body relative to the calcaneus of the foot to the rear edge of the wedge-shaped bone, and the rear foot is supported by the heel supporting protrusion and the foot is lifted Arch to achieve long-term comfortable support, reduce foot fatigue, and maintain the effect of correct foot posture.

Description

Insole structure

This creation discloses an insole structure, especially an insole structure that can support the arch of the foot.

Generally, commercially available insoles are used to support the inner side of the foot. Therefore, the insole usually forms a convex part near the inner edge of the corresponding foot to support the arch of the foot. However, when the arch of the foot falls, the support of the convex part will be affected. It makes the arch of the foot feel uncomfortable, and it is easy to feel the foreign body sensation, which can not achieve the support of the arch of the foot and has the effect of comfort.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above goals, after detailed design and careful evaluation, he finally got a practical creation.

This creation is an insole structure, which is a cushion body. The cushion body is a flat part at the front end connected to a protruding part at the rear end. The two sides of the protruding part respectively extend upwards, an inner edge abutment part and an outer side. The edge abutment portion, the raised portion protruding upwards with a heel supporting protrusion, the length of the heel supporting protrusion is relative to the distance between the front edge of a calcaneus of a foot and the rear edge of a wedge-shaped bone. The width position of the heel supporting protrusion is between 1/2 of a cuboid bone and 1/2 of a navicular bone facing the cuboid bone. The heel supporting protrusion extends and is concave toward the rear end of the cushion body. A recess.

With the above structure, the heel support protrusion can provide a mechanically correct support position of the foot, thereby changing the posture position of the foot and maintaining it in the correct posture, so that the bottom of the foot Fascia and muscles are in a relaxed state, in addition to providing better support and comfort, it can also reduce the fatigue of the foot.

1 to 5, the present invention discloses an insole structure, including a cushion body 10, the cushion body 10 is a flat part 12 at the front end connected to a protruding part 14 at the rear end, the two sides of the protruding part 14 are respectively An inner edge abutment portion 141 and an outer edge abutment portion 142 extend upward. The protruding portion 14 protrudes upwards with a heel support protrusion 16 whose height is smaller than the inner edge abutment portion The height of 141 and the height of the outer edge abutment portion 142, the height of the inner edge abutment portion 141 is greater than the height of the outer edge abutment portion 142, the length of the heel support protrusion 16 relative to a foot 20 Between the anterior edge of a calcaneus 22 and the posterior edge of a cuneiform bone 24, the width of the heel supporting protrusion 16 is relative to 1/2 of a cuboid bone 26 to a navicular bone 28 facing the cuboid bone 26 Between 1/2 of the ratio, the heel supporting protrusion 16 extends toward the rear end of the cushion body 10 to form a recess 18.

Continuing to refer to FIG. 1, the ratio of the farthest free end of the heel support protrusion 16 from the protruding portion 14 to the farthest free end of the heel support protrusion 16 from the flat portion 12 is 1:3, and the rear The ratio of the distance between the heel support protrusion 16 and the inner edge abutment portion 141 and the heel support protrusion 16 to the outer edge abutment portion 142 is 1:1.

Continuing to refer to FIG. 3 and in conjunction with FIG. 1, the protruding portion 14 forms a lower concave arc section 143 facing the axial free end of the flat portion 12, and both sides of the concave arc section 143 are respectively connected to the inner edge abutting portion 141 and the outer edge abutting portion 142.

Continuing to refer to FIG. 5 and in conjunction with FIG. 1, the heel supporting convex portion 16 is a slowly inclined slope toward the flat portion 12, and the heel supporting convex portion 16 is a sharply sloped slope toward the rear end of the cushion body 10 , The ratio of the length of the inclined surface that is slowly inclined to the steeply inclined surface is at least 3:1, the foot portion 20 steps on the flat portion 12 and the protruding portion 14 of the cushion body 10, and the heel supports The protrusion 16 supports the front edge of the calcaneus 22 of the foot 20 to the rear edge of the cuneiform bone 24 of the foot 20 to maintain the correct posture of the foot 20, and at the same time the calcaneus of the foot 20 22 will fall into the recess 18 of the cushion body 10 to relax the fascia and muscles at the bottom of the foot 20 in a relaxed state to provide long-term support and comfort.

Only the above is only one of the preferred embodiments of the present model, and should not be used to limit the scope of implementation of the present model; that is, all equal changes and modifications made in accordance with the scope of the patent application for the present model shall still belong to the present model Covered by the patent.
