Composite shoe midsole

This creation is about the shoes, especially the midsole of the shoe that is combined into two different materials. It has multiple effects such as cushioning, pressure, energy transmission, strong propulsion and dynamic balance.

According to the discussion of walking dynamics, the walking system first hits the ground with the heel, the weight moves from the outside of the foot to the toes, and then kicks out from the toes. Every step of walking, there will be 0.7 to 1.5 times the weight of the body weight on the sole of the foot, the reaction force will be back to the ankle joint, knee joint, in order to reduce the impact, the sole should have the function of elastic suspension. Thus, a wide variety of air cushion shoes are born. For example, Taiwan Patent No. I441602 provides a labor-saving airbag shoe that includes a heel labor-saving device, an arch labor-saving device, and a toe-saving device. Each labor saving device has an air bag portion. When the heel is pressed, the push force generated by the heel airbag pressure is transmitted to the airbag portion of the arch; when the arch is depressed, the arch airbag also generates a pushing force and transmits it to the toe airbag portion; At the moment of the toe, the toe airbag also generates a pushing force and releases pressure at the toe.

Taiwan Patent No. I375530 provides an air-cushioned shoe structure including an air cushion body, the air cushion body further includes an airbag portion and an inflating portion, and a connecting member is disposed between the airbag portion and the inflating portion, and the connecting member turns on the airbag portion and the inflating portion. When the inflated portion is under pressure, the gas available to the inflated portion flows toward the airbag portion.

The new patent No. M480281 of Taiwan provides a sole cushioning structure, in which a front accommodating groove and a rear accommodating groove are formed at the sole and the heel of the sole of the shoe, and a first buffer block is arranged in the front accommodating groove, and is accommodated in the rear. a second buffer block and an insertion slot are built in the slot; a sole hard plate is placed on the upper end of the sole of the shoe, the first buffer block and the second buffer block, and the sole hard plate corresponds to the heel portion. There is a hollow space, and there is a third buffer block below the heel portion. The third buffer block extends through the hollow portion of the sole hard plate and then abuts against the upper end of the second buffer block; thereby forming a cushioning effect and being easy to repair. Maintenance of the sole structure.

Taiwan Patent No. M472425 provides an air cushion type decompression insole comprising an insole including a heel portion, a arch portion and a forefoot portion, a cushioning airbag embedded in the heel portion, and a longitudinal arch airbag embedded therein In the arch part of the foot; the transverse arch airbag is embedded in the forefoot; the plurality of one-way valves are respectively arranged in the buffer airbag, the longitudinal arch airbag and the transverse arch airbag, so that the air outside the insole It flows into the airbags and prevents air from flowing backwards from the respective airbags; the gait is stabilized by installing corresponding airbags corresponding to different areas of the foot.

Although the above-mentioned air-cushion shoes are intentionally good, the air cushion function is achieved by relying on a plurality of airbags combined with the inflation pipeline, and the airbag is prone to collapse or displacement due to insufficient inflation, which significantly detracts from the overall use effect.

In addition, according to the aforementioned walking dynamics discussion, the walking system first hits the ground with the heel, the weight moves from the outside of the foot to the toes, and then kicks out from the toes. Therefore, each step, the sole and the position of the sole of the shoe are not the same. Therefore, whether the midsole made of a single material is sufficient to provide different degrees of support for different parts of the sole when walking, no doubt .

In view of this, the creators and others adhere to the good intention of excellence, and provide a composite shoe midsole to solve the above-mentioned conventional air-cushion shoes.

That is, this creation provides a "composite shoe midsole" which is made up of a sole with a soft and elastic EVA or PU material and a heel portion made of a TPU material with good texture and good support. The midsole of the shoe has the characteristics of front and rear brace to provide multiple effects such as cushioning, pressure, energy transmission, strong propulsion and dynamic balance.

Fig. 1 is an exploded perspective view of the present creation; Fig. 2 is an external perspective view of the creation.

Referring to FIG. 1 and FIG. 2 , the midsole of the present invention is a heel portion 1 made of EVA or PU material with good texture and light elasticity, and a heel portion 2 made of TPU material with good texture and good support. The composite midsole has the characteristics of front and rear brace to provide multiple effects such as cushioning, pressure, energy transmission, strong propulsion and dynamic balance.

The heel portion 2 further includes a bearing portion 21 in which the top surface is in contact with the sole of the sole, a support portion 22 in which the bottom surface is bonded to the rubber outsole, and a cushioning portion 23 located therebetween.

A positioning end portion 211 is defined to extend outwardly from both sides of the front end of the top surface bearing portion 21, and the positioning groove 11 corresponding to the top surface of the rear end portion of the sole portion 1 is used to improve the accuracy of the joint between the sole portion 1 and the heel portion 2.

The front end of the bottom support portion 22 extends outwardly to form a shovel portion 221, and corresponds to an overlapping groove (not shown) on the bottom surface of the rear end of the sole portion 1, so as to improve the stability when the sole portion 1 and the heel portion 2 are butted.

The cushioning portion 23 located between the top surface bearing portion 21 and the bottom surface supporting portion 22 has a continuous triangular truss carrying longitudinal pressure, and the top corner 231 of any triangular truss is connected with the top surface bearing portion 21; The two bottom corners 232 of the frame are connected to the bottom support portion 22, and the formed mountain-type structure has strong support and stability, can reduce energy consumption during walking or running, and maintain dynamic balance during exercise.

The above two apex angles 231 and the two bottom corners 232 are connected to each other to form a hollow compartment 233 for absorbing pressure.

Corresponding to the apex position of any triangular truss of the cushioning portion 23, at the bottom surface The support portion 22 protrudes upward to form a triangular rib portion 222. The triangular rib portion 222 not only has the effect of reinforcing the strength of the bottom support portion 22 having a small thickness, but also can effectively combine the shock absorbing effect of the hollow space 233 to enable effective Absorbing the reaction force when the bottom support portion 22 contacts the ground, and reducing the consumption of dynamic energy by the support and stability provided by the mountain-type structure of the cushioning portion 23, and transmitting the energy to the sole 1 quickly, and then using the sole of the foot The EVA's texture is light and elastic, and the effect of labor-saving is achieved.

When the sole portion 1 and the heel portion 2 are corresponding to the positioning groove portion 11 corresponding to the positioning groove 11 as shown in FIG. 2, and the shovel portion 221 is butt-bonded to the overlapping groove, it is bonded to the rubber outsole 3 having good wear resistance. Let the three be combined into one.

According to the aforementioned walking dynamics, the heel first touches the ground. For the non-flat feet, the outer side of the foot will follow the ground, and finally the whole pressure is released by the thumb and kicked forward. According to the composite midsole provided by the walking dynamics, the heel portion 2 made of TPU material with good texture and good support is used to bear the pressure of the heel landing, and at the same time, the air cushion function of the cushioning portion 23 is used. One relieves the reaction force on the heel, and the two push the rebound energy forward to the toe through the outside of the foot. Since the sole 1 of the foot and the toe are made of EVA or PU material with good texture and light elasticity, In the process of energy conduction, it can advance faster and finally reach the ultimate goal of dynamic balance.
