Description

a sole

technical field

The utility model relates to a component part of a shoe, in particular to a shoe sole.

Background technique

Now people wear shoes more and more require comfort and suitable for sports, so the shoes produced and sold now, especially sports shoes, all have some special structural designs, so that people can wear them comfortably.

These designs generally include the design of the upper or sole. The upper uses holes or cotton materials to increase air permeability. The sole is thickened with a space in the middle, which also increases air permeability. Some special sole materials are used to increase shock absorption, etc. . If people need to walk for a long time, although the existing breathable and shock-absorbing shoes will be more comfortable to wear, but because the present shoes do not have the function of helping and boosting, they will still get tired after a long time and affect walking. .

Therefore, it is hoped to improve the existing ones on the soles. According to the structure and mechanical phenomena of the human foot, the balance point and buffer force are used to adjust the pressure of the foot metatarsals and leg joints, and generate power to help walking, thereby creating an improved walking posture. The overall coordination allows people to walk with a relaxed posture.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model.

A kind of sole, comprises three layers, is respectively inner bottom layer 1, middle bottom layer 2 and outer bottom layer 3; The upper surface of described inner bottom layer 1 is close to the sole of the foot, and nanofiber antibacterial inner pad 11 is arranged at the sole of the front foot and the back heel, There are bumps on the inner pad 11, which can slightly massage the soles of the feet. The middle of the main part under the surface protrudes downwards to form a balanced support bump 14, which is matched and fixed in the groove 24 in the middle of the middle bottom layer 2. The inner bottom layer 1 Between the bottom and the middle bottom 2, the groove 24 is fixedly provided with front and rear metal elastic devices 21, 22 respectively, so that the front and rear feet of the front foot and the rear foot are in the undulating state when walking, so that the front end and the rear end of the inner bottom layer 1 are under the principle of leverage. Make a natural front and back fit, produce uniform force on the foot, and produce a boosting effect through the mutual cooperation of the front metal elastic device 21 and the rear metal elastic device 22, and the rear end of the rear metal elastic device 22 has a downward compression spring 221 It is fixed on the heel pad 4 to jointly form the overall boosting effect. The outer bottom layer 3 is located under the middle bottom layer 2, wraps the middle bottom layer 2 and the inner bottom layer 1 upwards, and connects the heel pad 4 backward. It is made of elastic and wear-resistant rubber Composed of anti-slip layer and nanocomposite materials.

The outer bottom layer 3 has an open inner seam 34 at the heel, and there is an adjustment hook 33 upwards at the heel, and there is a row of adjustment grooves 43 at the bottom of the heel pad 4 that open outwards with a plurality of different heights up and down. The crotch 33 is embedded in any adjusting groove 43 of the heel pad 4, which can regulate the height of the sole structure, and provides the option of height adjustment for adapting to different heel heights or requiring different sole heights. The adjustment groove 43 can be made into two, divided into a first adjustment groove and a second adjustment groove.

There is a hemispherical soft protrusion 12 in the center of the upper surface of the inner bottom layer 1, which can relieve the fatigue of the arch of the foot for different forms of the arch of the foot.

The front and rear metal elastic devices 21, 22 are respectively provided with noise-reducing fixing blocks 13, 23 on the inner bottom layer 1 and the middle bottom layer 2, which can be made of nanocomposite materials, not only for the front and rear metal elastic devices 21, 22 in motion. To reduce noise and fix the effect, and the noise reduction fixed blocks 13,23 that have up and down can also produce up and down mutual damping force when colliding.

In the middle of the bottom of the outer bottom layer 3 and between the inner seam 34 of the opening and the main body of the outer bottom layer 3, a shock absorbing block 32 is arranged, and the space of a concave arc is arranged on the shock absorbing block 32, which plays the role of shock absorption. The rubber breathable strip 31 that connects the edge of the inner bottom layer is arranged on the outer bottom layer 3, is connected on the heel pad 4 from the front end of the outer bottom layer, and the air vent 311 is arranged before and after the breathable strip, so that the effect of air circulation is produced in the shoes.

The ground-touching bottom surface of the outer bottom layer 3 has a dotted arc-shaped pattern high in the middle and low in the surroundings. The high dotted arcs in the surroundings are made of hard rubber materials, and the protruding arrangement structures of the low dots and semi-brackets in the middle are made of soft rubber. The material is constructed to enhance the grip and anti-slip on the ground.

Described heel pad 4 is inverted " V " shape, is made to have the curve shape that conforms to the back of heel, and air vent 41 is arranged at the top, and the adjusting groove 43 that is connected with outer bottom layer 3 is arranged at the rear end below, and the front end edge is connected with outer bottom layer 3, The middle is in contact with the upper surface of the inner bottom layer 1, and there is a nanofiber antibacterial inner pad 42.

Through the supporting balance point in the structural design, the cooperation of the heel pad and the front and rear metal elastic structure devices, the adjustment of the heel height, the ventilation and humidity circulation and other functions and materials, the sole achieves the effects of power assistance, shock absorption and comfortable wearing. .
