Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a sole for footwear that is used for footwear and provides ventilation and massage to the foot.

(Prior Art) The Sandmeyer patent shown in US Pat. No. 4,215,492 discloses a shoe sole that can be attached to the sole of a shoe. This shoe sole has an inner chamber in the sole of the shoe, and air is forced into the heel and toes by allowing air to enter and exit from the inner chamber, allowing the user to I try to make the shoes more comfortable to wear. This shoe sole has an upper layer sheet and a lower layer sheet, and a U-shaped separator is incorporated between the sheets in the portion corresponding to the heel, which provides ventilation and massage to the sole of the foot. It is becoming possible to obtain

(Problem to be solved by the invention) However, the shoe soles shown in the above publication have
There are drawbacks as described below.

First, if a shoe sole with this structure is applied to low-cost footwear, such as slippers, both the upper and lower sheets must be manufactured, and a U-shaped separator must be glued between them, which increases manufacturing costs. It is time consuming and increases manufacturing costs.

Further, since the protrusions are not provided on the entire surface of the shoe sole, but only on the front end of the shoe sole, the substantial effect of massaging is low. If a bump were also provided at the heel in order to increase the massaging effect of the bump, the heel would bulge and become too high, making it uncomfortable to wear.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a simple structure that can enhance the massaging action and the ventilation action while suppressing manufacturing costs.

[Structure of the invention] (Means for solving the problem) The present invention for achieving the above object includes a grid-like part in which a large number of ventilation holes are formed, and one of the upper surfaces of the intersections of the grid-like part. The upper convex bead part has an upper convex bead part provided at the center, and a lower convex bead part provided on the lower surface of the intersection where the upper convex bead part is not provided, and the upper convex bead part or the lower convex bead part Each is located so as to be surrounded by four adjacent lower convex bead portions to upper convex bead portions with the grid portion as a diagonal line, and when stepped on by a foot, the upper convex bead portion It is characterized by being pressed against the sole of the foot and displaced downward to generate compressed air, and guiding the compressed air toward the foot to massage and ventilate the sole of the foot. It is a sole for footwear.

(Function) When the footwear sole of the present invention having the above structure is used for footwear, the upper convex bead part receives the weight of the sole of the foot, and is located below each convex bead part. The air is compressed and flows upward through the ventilation holes to the soles of the feet, improving the wearer's comfort. Also,
Since the sole of the present invention has an upper convex ball portion formed over its entire upper surface, the massaging area for the foot increases, further increasing the massaging effect.

(Example) Hereinafter, the present invention will be described in detail based on the illustrated embodiment of the present invention. The footwear sole 1 of the present invention shown in FIGS. 1 to 4 is used as an insole 1 that is detachably attached to the sole of a shoe. FIG. 2 shows the sole or insole of the present invention mounted on the sole 12 of a shoe 2.

The insole 1 of the present invention has a single-layer structure, and its overall planar shape is shown in FIG. 1, and its main parts are shown in FIG. It has a grid-like portion 13 formed of members. This lattice part 1
On the upper surface of 3, hemispherical convex beads or convex beads 11 are formed to protrude upward at every other intersection, and convex beads or convex beads 12 are formed on the lower surface of the other intersections. It is formed to protrude downward.
A large number of ventilation holes 10 are formed between these convex portions 11 and 12 and the grid portion 13.

As shown in the figure, each upper convex bead portion 11 is surrounded by four lower convex bead portions 12 located at the vertices of each diagonal, with the adjacent grid portion 13 as a diagonal line. These are centrally located. Similarly, the lower convex portion 12 is surrounded by four upper convex portions 11 located at the vertices of each diagonal, with the adjacent lattice portion 13 as a diagonal line. It is located in the department. Therefore, as shown in FIG. 1, the upper and lower convex portions 11 and 12 are located apart from each other and do not overlap when viewed from above and below. In the illustrated case, the maximum diameter in the horizontal direction of the lower convex bead portion 12 is approximately the same as the width dimension of the lattice-like portion 13, and the similar maximum diameter, that is, the cross-sectional area of the upper convex bead portion 11, is Although it is set larger than that of the lower convex ball part 12, this can be set to any diameter.

In addition, although each of the convex beads 11 and 12 has a hemispherical shape in the illustration, it is not limited to this shape, and may have a more pointed shape or a flattened shape. It may be a shape, etc.

When shoes equipped with such an insole 1 of the present invention are used, as shown in FIG. 4, the weight of the foot causes the upper convex ball portion 11 to press against the underside of the foot.
The weight is supported by the lower convex ball part 12 located on the upper surface of the sole 21. As each upper convex ball part 11 is pushed downward, the air occupying between the insole 1 of the present invention and the sole 21 is compressed, and the air is compressed through the many ventilation holes 10 of the insole. It flows into the gap between the top surface of the shoe 1 and the sole of the foot, and at the same time massages the sole of the foot.

FIG. 5 is a diagram showing a case where the sole according to the present invention is fixed to the bottom surface of sandals 2 and is used as an insole. In this case, a large number of fitting protrusions 14 are provided on the bottom surface of the insole 1 along the outer periphery of the insole, and the fitting holes 22 into which these fitting protrusions 14 fit are formed in the respective fitting protrusions. The footwear, that is, the sandal sole 21 is formed in correspondence with the portion 14. In this way, the illustrated sole or insole 1 is fixed to the sandal by the fitting protrusion 14.

[Effects of the invention] As described above, according to the invention, the sole of the invention, that is, the shoe sole, is formed of a single layer or a single sheet-like lattice member 13 having a large number of ventilation holes 10. Therefore, the manufacturing cost is low, and the feet can be ventilated and massaged. Also,
Since the convex beads 11 that protrude upward and the convex beads 12 that protrude downward are alternately overlapped, when the weight of the foot is applied to the upper convex beads 11, the pressure is applied to each of the convex beads 11. It is distributed over the entire bottom surface of the shoe via the lower convex beads 12, and the gap S between the lower convex beads 12 is displaced, resulting in a highly elastic sole. The balls will not pierce and the soles of the feet will not hurt.

Furthermore, when weight is applied to the sole, the large number of upper convex balls 11 are pressed downward, and the air between the bottom surface of the sole of the present invention and the sole is compressed, and the large number of ventilation holes are formed. Since the compressed air flows from above the sole, ventilation within the shoe can be easily achieved without providing a complicated ventilation path, and the ventilation effect can be reliably obtained.
