Description

Shock-absorbing midsole of sports shoes

technical field

The utility model belongs to the technical field of shoemaking and relates to a shock-absorbing midsole of sports shoes.

Background technique

Ordinary sports shoes mostly use a solid midsole structure, using the physical properties of midsole materials such as EVA for cushioning, but limited by the performance of the material itself, there is a compression limit and a rebound limit after receiving the impact force from the sole of the foot. It cannot respond quickly, and after a long time of use, the material will age and collapse, which will not play a cushioning role.

The existing midsole structure of solid material produces slight deformation after the sole of the foot receives the impact force. This is due to the low shrinkage limit of the material itself and the limited release of the impact force, so it will produce a shock feeling; and the midsole structure The elastic membrane can be quickly and reversely deformed according to the force, and the material shrinkage limit is high, which can release more impact force and reduce the shock. The existing solid material midsole structure has a slow rebound rate and cannot provide rebound force when the sole of the foot makes a starting action, which is commonly known as "non-heeling".

Detailed ways

The utility model will be described in detail below in conjunction with specific embodiments.

The utility model is shown in Figures 1 to 9, the material of the upper stabilizer 1 is preferably plastic, tpu (thermoplastic polyurethane elastomer rubber), glass fiber, carbon composite material and other hard materials, and the upper stabilizer 1 is stabilized by the heel Part 11 and upper middle end link ring 12 constitute, upper middle end link ring 12 is the annular elastic hard material of hollow foot shape, upper middle end link ring 12 wide 5 ~ 15mm. The heel stabilizer 11 is fixed to the rear part of the upper midsole link ring 12 for the shape of the heel of the shoe;

The elastic membrane 2 is made of a 3-8 mm thick high-strength and high-elastic material such as a natural latex sheet or a rubber sheet. The material of hollow midsole 3 is preferably hard materials such as plastics, tpu, glass fiber, carbon composite material, and hollow midsole 3 is made of heel support sheet 31, outer support sheet 311, inner support sheet 312, toe support sheet 313, lower center The bottom link ring 32 and the outer bottom 33 constitute; the heel support sheet 31, the outer support sheet 311, the inner support sheet 312, and the toe support sheet 313 are fixedly connected together by the lower middle bottom link ring 32 and the outer bottom 33. Wherein the heel support piece 31, the outer side support piece 311, the inner side support piece 312, the toe support piece 313 high 20 ~ 40mm, thick 5 ~ 15mm; The lower middle bottom link ring 32 is identical with the last middle bottom link ring 12 shape specifications.

Use lathe processing preferred metal to make upper clamp 4, right clamp 41, lower clamp 42, left clamp 43. The upper clamp 4, the right clamp 41, the lower clamp 42, and the left clamp 43 respectively step up and fix the four sides of the elastic membrane 2, and apply traction to the four sides on average, so that the elastic membrane 2 is pulled apart evenly. When the surface tension of the elastic membrane 2 reaches 60-150 kg , while maintaining the tension, use high-strength glue to fix the upper stabilizer 1 and the hollow midsole 3 on the front and back sides of the elastic membrane 2 respectively, so as to ensure that the upper midsole link ring 12 and the lower midsole link ring 32 correspond up and down. , and then apply pressure up and down, until the glue is solidified and stable, cut off the excess part of the elastic membrane 2 according to the cutting track 5, and obtain the molded midsole 6.

Use preferred soft materials such as fabrics, leather, artificial fabrics, etc. to make the integrated shoe upper 7. The vamp 7 has different specifications, and its function is to wrap and fasten the vamp stabilizer 1, which can be made according to various styles of shoes. Open the mold to make the insole 8, which is made of preferred foaming materials. The insole 8 is composed of an outer pad 81, an inner pad 811, and an insole inlay 82. The outer pad 81 and the inner pad 811 respectively fit around the inner and outer curves of the human foot , the edge shape of the insole inlay 82 is the same as the shape of the inner ring of the upper midsole link ring 12, and the thickness is the same as that of the upper midsole link ring 12. The insole inlay 82 can be embedded in the upper midsole link ring 12.

Die opening makes rubber outsole 9 as sole, preferably wear-resistant rubber is made, and bottom surface has anti-slip pattern, thick 5～10mm. The insole 8 is embedded in the molded midsole 6, and the molded midsole 6 is fixed on the rubber outsole 9. Glue is preferably used to fix the above components to complete the production of the entire shock-absorbing sports shoe midsole.

When moving, when the foot falls to the ground and touches the bottom surface, the rubber outsole 9 exerts grip to increase the friction between the sole and the ground to stabilize the action. Since the sheet 313 is made of an elastic hard material, the deformation is small but the supporting stability is very strong. When the sole of the foot releases the impact force further downward, the elastic membrane 2 will deform according to the force application part of the sole of the foot, absorb and store potential energy, and slow down the shock; Start the next movement after leaving the ground, and the elastic membrane 2 quickly restores and releases the potential energy absorbed during its deformation, which can play a role in boosting the speed of movement; the insole 8 acts as a buffer between the sole of the foot and the elastic membrane 2, and the upper is stable The part 1 and the integrated upper 7 tightly wrap the foot to ensure the support and stability of landing and starting actions during sports.

The utility model also has the advantage that after the structure is assembled stably, the elastic film will maintain the surface tension applied in the stretched state. The midsole is a hollow structure, which provides enough deformation space for the shock absorption of the soles of the feet. When the human body performs landing actions during exercise, such as running, jumping, and when the soles of the feet produce downward impact forces, the elastic membrane will have a shape according to the magnitude of the force. Deformation occurs, and a part of the impact force is released; when the human body is in motion, starting actions such as jumping, starting, and pedaling downward to generate downward pressure impact force, the elastic membrane will gather potential energy under the downward force. Creates a rebound that helps increase the rate of movement. Due to the huge tension on the surface, the midsole structure of the elastic film will gather potential energy when the sole of the foot is pressed down before starting. Once the sole of the foot is off the ground, the potential energy is released, and the elastic film quickly recovers and deforms to generate rebound force, which is powerful for improving the starting action. speed and explosiveness.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form, for example: the hollow midsole 3, the vamp stabilizer 1 and the integrated vamp 7 can be designed in different shapes; The tension of the elastic membrane 2 can be adjusted differently according to the needs, and it can also be used locally on the forefoot or the heel; the heel support sheet 31, the outer support sheet 311, the inner support sheet 312, and the toe support sheet 313 are designed to other shapes and sizes; The assembly process of air bottom 3, upper stabilizer 1, and elastic film can also be secondary molding or other combinations; any simple modification made to the above embodiment according to the technical essence of the present utility model is equivalent to change and modification. It belongs to the scope of the technical solution of the utility model.
