Description

[Detailed explanation of the invention] Industrial application field This invention relates to health sandals that provide appropriate stimulation to the soles of the feet and improve blood circulation without causing any pain or discomfort even when worn for long periods of time. be.

Conventional Disadvantages Conventionally, such health sandals are provided with a large number of protrusions on the surface of the sandal, that is, the top surface that is in direct contact with the sole surface.

This protrusion is also made higher and larger at the arch than the heel and base of the foot, so that it is distributed evenly over the sole of the foot, providing stimulation to the sole of the foot.

Further, all the protrusions are integrally molded from the same material as the base, for example, synthetic resin.

Problems to be Solved by the Invention When the pedestal portion and the protrusion are integrally molded as described above, the protrusion must have a certain degree of strength in order to support the body weight. For this reason, all the protrusions are filled (solid). Therefore, even if the soles of the feet can be stimulated, wearing them for a long time can cause pain and discomfort.

In order to prevent this, if the protrusions are made of a soft material, the edges of the protrusions are likely to break, resulting in poor resilience and durability.

Means for solving the problem In this invention, a large number of protrusions are provided in a protruding shape according to the shape of the sole of the foot, and each protrusion is made hollow to provide a certain degree of strength to the outer peripheral wall of the protrusion. In addition to supporting the body's weight and providing durability, the top surface of each protrusion in contact with the sole of the foot is thinner than the outer peripheral wall and has an uneven shape with the center slightly protruding, thereby providing stimulation to the sole of the foot. . This hollow protrusion and the uneven surface on its top provide the necessary strength and resilience, and soften the contact sensation with the sole of the foot so that it does not cause pain or discomfort even when worn for a long time. This is what I did.

Embodiments Next, the health sandals of this invention will be explained with reference to embodiments shown in the drawings. FIG. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is an enlarged sectional view of one protrusion.

In the embodiment of FIGS. 1 to 3, 1 is the main body of the sandal, which is manufactured by conventional manufacturing methods.

Sponge, synthetic resin, natural leather, and other materials are used, and the straps 2 are cut into appropriate sizes and shapes, and the thong 2 is attached to them. The shape of the thong 2 is not limited to that shown in the drawings, and various shapes may be adopted. The sandal body is designed to be comfortable to wear, and to have an appropriate height (thickness) and cushioning properties depending on the intended use, such as indoor shoes or outdoor shoes.

Further, a protruding plate 3 is provided integrally with the main body 1 on the surface layer of the sandal main body. A large number of protrusions 4 are provided on the protruding plate 3 to provide appropriate pressure stimulation to the sole surface of the foot. The protrusion 4 is large and high at the arch of the foot, and smaller and lower at the heel, the base of the toes, and the toes. The height and size of the protuberance can be varied to ensure better familiarity over time. In addition, the intervals between the arrangement may also be changed.

Each protrusion 4 of the protrusion plate 3 formed of synthetic rubber or synthetic resin is hollow as shown in FIG. The wall thickness is determined so as to support the load and provide appropriate elasticity, restorability, and durability, and the top surface 42 is made to be an uneven surface. The top surface is configured such that the height of the tip of the outer peripheral wall 41 and the center of the protrusion are different. In other words, the central portion is raised slightly higher than the outer peripheral portion, and the top surface 42 of the central portion is
a is higher than the outer circumference top surface 42b, and both top surfaces 42
The entire top surface is made uneven so that 42c between a and 42b is slightly thinner and lower, so that the top surface of the central portion contacts the sole surface of the foot, providing appropriate softness and providing appropriate stimulation. Eggplant.

Air is filled in the hollow portion of the protrusion 4 when the protrusion plate and the main body are joined together.

The present invention can also be used as an insole by joining the protrusion plate to the insole base material.

Effects of the invention By providing a large number of hollow protrusions with uneven tops on the surface of the sandal in a raised shape that matches the shape of the sole of the foot, we have created a new design using synthetic resin and synthetic rubber that is similar to conventional sandals. Even if the protrusions are shaped using a polyurethane rubber, they are strong, have appropriate resilience and load-bearing properties, and the part that comes in contact with the sole of the foot is soft and feels good, and provides appropriate stimulation to prevent pain even when worn for a long time. It does not cause discomfort and has the effect of improving blood circulation and promoting health.
