[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe midsole or shoe sole.

[0002]

2. Description of the Related Art As is well known, there is an acupoint on the sole of a foot as referred to by massage, and it is said that health can be maintained by stimulating this acupoint. For this reason,
In slippers or sandals for indoor shoes,
A plurality of protrusions protrude from the upper surface of the bottom plate, and the heights and positions of the protrusions differ depending on the position of the stimulating acupoint. Some of the protrusions stimulate the soles of the feet by stepping on the protrusions, thereby providing a massage effect.

[0003]

[Problems to be solved by the invention] However, wearing shoes using such a sole (or an insole) does not cause much problem such as fatigue when used for a short time. In some cases, it was too direct to stimulate the soles of the feet, so they passed through the comfort and even felt pain. For this reason, shoe soles having the above-mentioned projections have been put to practical use limited to sandals and slippers, but have not been put to practical use in shoes.

Accordingly, an object of the present invention is to provide a shoe midsole or shoe sole that provides a massage effect without causing pain even when used for a long time.

[0005]

A feature of the present invention is that a plurality of projections are provided on an upper surface of a bottom plate, the upper surface of the bottom plate is covered with a cover, a fluid is injected into a space between the bottom plate and the cover, and sealing is performed. It is in the place.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

The present invention comprises a bottom plate 1, a plurality of projections 2 provided on the bottom plate, a cover 3 welded to the outer periphery of the bottom plate, and a fluid injected into the bottom plate and the hollow portion of the cover. W.

The sole plate 1 is formed of polyvinyl chloride, which is a thermoplastic synthetic resin, and has the outer shape of the midsole or sole of the shoe as shown in FIG. 1 and its outer periphery as shown in FIG. A wall portion 11 is formed integrally with the portion, and the inside of the wall portion is a concave portion 12 corresponding to the area of the sole, and the outer periphery of the wall portion is thinned through a step. 13
It has become. The thin portion 13 has a relative meaning with respect to the wall portion 11.

A plurality of projections 2 are formed on the upper surface of the concave portion 12 of the bottom plate 1 at predetermined intervals, and these projections are columnar as shown in FIG. It is tinged, and the protrusions at the center and the arch of the shoe sole are higher than the protrusions at the other parts. The projections may be mounted in the recess 12 in advance as a separate member from the bottom plate 1 as shown, or may be formed integrally with the bottom plate.

The cover 3 is made of the same thermoplastic synthetic resin as the bottom plate 1 made of polyvinyl chloride.
A thick portion 31 is formed on the outer circumference via a step. The thickness of the thick portion 31 is substantially the same as that of the thin portion 13 of the bottom plate 1. When the lower surface of the thick portion 31 of the cover 3 is welded to the upper surface of the thin portion 13 of the bottom plate 1 by high frequency means, the space between the cover 3 and the bottom plate 1 becomes hollow. Since the bottom plate 1 and the cover 3 are made of the same material, they are easily integrated when welded. And the welding surface is
Although only the entire surface of the thin portion 13 of the bottom plate 1 and the thick portion 31 of the cover 3 is assured in preventing the outflow of a fluid such as water W,
Further, if the joining surfaces of the steps are also welded, the outflow of the water W can be more reliably prevented. The cover 3 must buckle when pressure is applied and restore again when no pressure is applied.

The cover 3 covers the plurality of projections 2. Water 3 is injected into a closed space between the bottom plate 1 and the cover 3 through an injection hole (not shown) formed on the outer periphery of the bottom plate and the cover, and the injection hole is sealed. To seal the interior.

Next, the operation of the present invention will be described.

When the shoe using the insole or the sole according to the present invention is worn, a plurality of projections 2 apply a vertical stimulus to the sole of the foot. Further, when pressure is applied to the bottom plate 1, the water W injected into the space between the cover 3 and the bottom plate 1 disperses. It is added to the sole of the foot. Further, since the stimulus by the plurality of protrusions 2 is relieved by the water W and is not transmitted directly,
You will not feel any pain even after long hours. Further, when pressure is applied to the cover 3, the plurality of projections 2... Serve to press the cover, so that sea sickness caused by the movement of the water W can be suppressed. In particular, the projection 2 at the center of the sole and at the arch of the arch rises higher than the projections at the other parts, so that a flat foot gives even stronger stimulation to correct it to a normal foot.

[Effects of the Invention] The shoes according to the present invention provide a massage effect without causing pain even when worn for a long time, can absorb shocks during walking, and reliably prevent the outflow of fluid. You can do it.
