Abstract

<P>PROBLEM TO BE SOLVED: To solve a disadvantage that a wearer's feet become sweaty and that the feet become chilly due to the sweat. <P>SOLUTION: A shoe sole (inside) are much perforated, or the much perforated shoe sole is laid in the inside of a shoe, whereby ventilation and pointillage effect are improved. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a shoe sole (inside), slippers, sandals, and an insole. Many holes are formed in the insole and the upper sole. Some have improved their effectiveness.

Technical background

There have been many types of shoes and insoles in the past, and many inventions have been made, but there are, among other things, shoes with many small protrusions lined up and some examples with small holes (about 3 mm).
Examples of this include Patent Document 1 and Utility Model Document 1, and examples disclosed in Patent Document 2 and Utility Model Document 2 are examples of holes (small holes).

Problems to be solved by the invention

  However, the conventional arrangement of small protrusions is painful and uncomfortable to wear, and even if a hole has a hole in the insole or the whole with a thing similar to the present invention, it is small. A hole (2 to 3 mm) as a ventilation hole cannot be said to have sufficient ventilation, and the present invention has an object to improve comfort and ventilation by arranging the holes in large holes.

Means for solving the problem

  In order to solve this problem, the invention of claim 1 is to uniformly provide a large number of holes (round holes: 5 to 10 mm, intervals of 8 to 15 mm) on the entire bottom of the shoe sole (inside), slippers, sandals and insole. Opening improves heat retention, breathability (exclusion of dampness), and new foot pot massage effect.

  In addition, the invention of claim 2 can have various shapes such as round holes, square holes, flower-shaped holes, heart-shaped holes, etc., and includes combinations thereof. Improvement and comfort are brought about.

  Further, the invention of claim 3 shows the material of the part where the hole is made, and the cushioning property is increased by using a sponge-like material, air flows in and out of the hole, and the moisture absorbed in the material is dried. It is also possible to change the comfort according to the application by changing the thickness and hardness of the sponge material (during production).

The invention's effect

  According to the present invention, the humidity inside the shoe is lowered, and the heat retaining property of the foot, appropriate air permeability, comfort of wearing, and feeling of movement are improved.

BEST MODE FOR CARRYING OUT THE INVENTION

  FIG. 1 is a plan view of an insole for improving comfort, characterized by having many round holes (7 mm round × 10 mm pitch) in the sole of the shoe. As shown in the figure, the hole effect can be obtained on the entire sole by arranging holes uniformly on the entire bottom surface.

  FIG. 2 is a plan view of the insole of a shoe for improving comfort, characterized by having many round holes in the sole of the shoe, as in FIG. 1, but the size of the round holes is increased to a pitch of 10 mm round × 12 mm, The arrangement is also changed. In addition to those shown in the figure, there are various other ways of arrangement, such as a wave shape, an ellipse, etc. centered on a concentric circle.

  FIG. 3 is a plan view of a comfort-enhancing sole characterized in that the shape of the hole is changed and there are several combinations. By changing the shape of the hole as shown in this figure, the desire to wear is improved.

Fig. 4 shows the change between the state where the foot is attached to the round hole and the state where the foot is released. The shoe deforms due to the pressure of the foot and pushes out the air in the hole, and the air is bent and pushed by the surrounding sponge cushion. , Chained with cushions, holes, and cushions, and finally pushed out and pushed out to the heel outside the bottom material, the air reaches the opening of the shoe to the foot (insole, then mixed with the outside air) .
When the foot is lifted up a little, the cushioning material returns to the original mold, the hole mold returns to its original volume and promotes the backflow of air. In addition, the contact with many holes and feet provides a softer massage effect than conventional wart-type stimulating shoes and does not hurt, making it comfortable (including slippers, sandals, and insoles). As its synergistic effect, there are many advantages such as wanting to wear, wanting to walk or run, and getting warm.

The material for the sole (including the insole) of these shoes may be a normal material such as urethane sponge or urethane rubber.
In addition, the shape of many holes can be round holes, triangular holes, polygonal holes, flower shapes, heart shapes, and many other variations, and combinations thereof are possible, and there are various patterns for arranging them.

  Since the shoes, sandals, slippers, and insoles according to the present invention can be industrially mass-produced, they have industrial applicability.

  It is a top view of the insole which improves the comfort which opened many round holes (7 mm circle x 10 mm pitch) of the insole.   Although the insole has many insoles with a large number of round holes (10 mm circle × 12 mm pitch), the arrangement is shown in FIG.   This is an example in which three types of holes (8 mm round hole, 8 mm triangle on the side, 12 mm ellipse on the long side) are combined and arranged on the insole. The arrangement is a corrugated shape with a center R of 100 mm.   FIG. 4 is a partial view showing a state where a foot hits a hole and pressure is applied, and a state where the foot is raised and pressure is lost.
