Abstract

Usage: in the shoe industry to improve performance while enhancing the massage effect. SUMMARY OF THE INVENTION:. The inserted massaging pneumatic insole is made in the form of a sealed chamber of two layers of elastic material connected together around the perimeter. The camera is equipped with a nozzle and a frame element. The nozzle is made of thin-walled material and is located on the inside of the alternating part of the insole. The pipe provides control of the air volume of the chamber. The frame element is rigidly connected to the lower layer of the chamber. In this case, both layers of elastic material are duplicated by a non-stretchable material or the entire insole is covered externally with this material. 3 ill.

Description

The invention relates to widely used insoles and can be used both in everyday indoor and outdoor shoes, as well as working, sports, orthopedic and therapeutic shoes. .

The aim of the invention is to provide a supplementary insole combining comfort and sufficiently high foot protection with an effective massaging effect on active sections of the sole.

Figs. 1a, b and 2a, b show the design of an insertable massaging pneumatic insole in two embodiments;

In both cases, it consists of three main parts: the base of the insole 1, the air chamber 2 with a nozzle of thin-walled material 3, and fabric cover 4.

In the first case (Fig. 1), the initial elastic material for the manufacture of the air chamber 2 is duplicated by non-expanding material 4, and in the second (Fig. 2), the coating of the air chamber 2 is inseparably connected to the base

insoles 1, non-expandable material 4 is carried out jointly.

The base of the insole 1 is a thin elastic plate of the type of kohemite obtained by cutting according to the technology operating in the shoe industry.

The air chamber 2 consists of two isometric layers made of thin-walled elastic material such as rubber, which are joined along the perimeter by vulcanization to form a covering edge of the connector. At the same time, a pipe 1, similar to that used for a bicycle nipple device, with a size of about 2x4 (two millimeter channel, with an outer size of four millimeters) and a length of 55-60 millimeters is vulcanized in the connector of the halves of the inner side of the alternating part.

The air chamber 2 is inseparably connected with the bottom layer to the base of the system 3 by gluing.

When the camera 2, not duplicated by the fabric (Fig, 2), it together with the base 1 pasted

It is a strong non-expanding fabric 4 overlaid on top (with the outlet pipe through the hole) and bending the ends to the base from the bottom.

Fig. 3 shows three typical phases of functioning of an in-line massaging pneumatic insole, corresponding to the main positions of the foot in the dynamics of movement. Position a corresponds to the initial stage of movement of compressible air from the exact zone through the metatarsal arch to the nose. Position b is characteristic of the stationary position of the foot and that particular case during movement, when the center of gravity of the body is within it.

The position in corresponds to the active movement of compressible air from the nose zone through the ankle to the exact.

Based on the foregoing, it seems possible to conclude that the claimed solution has significant differences. They consist in the use of an air chamber such as a thin-walled non-tight casing with a nozzle placed on the inside of the insole part of the insole, and a design that allows the chamber to be filled with an adjustable air volume to achieve the optimal combination of comfort, protection and effective massaging effect on active sections of the sole and through them a beneficial effect on internal organs,

The proposed insole meets the task posed in the application - it comfortably supports the foot over the entire surface of its sole, significantly lowering the specific pressure on it, protects against overloads, retains heat, makes gait more elastic and easy.

Claims (1)

SUMMARY OF THE INVENTION An insertable massaging pneumatic insole made in the form of a sealed chamber of two layers of elastic material interconnected around the perimeter, characterized in that, with in order to improve operational properties while enhancing the massaging effect, the chamber is equipped with a pipe made of thin-walled material located on the inside of the variable part of the insole to regulate the air volume inside the chamber, and a frame element rigidly connected to the lower layer of the chamber, both layers of elastic material being duplicated by the expandable material or the entire insole is coated externally by the non-expandable material.
