Description

Buffer support structure in shoes

The present invention is an improved design of the support structure in the shoe, which not only provides support for the user's sole and the heel, but also provides support for the arch portion of the user's sole to achieve the comprehensive support of the sole of the foot.

Generally, the inside of the shoe is provided with a cushioning body to reduce the reaction force of the ground to the sole. A flexible midsole is placed in the shoe, the most common cushioning structure. The elastic midsole can alleviate foot pain caused by standing for a long time or walking for a long time.

Most of the flexible midsole is made of latex or rubber foam and has elasticity. In the state where the user naturally walks, the heel strikes the ground first, and then the entire sole is leveled, and then the heel is placed on the ground after the heel is off the ground. During the process, the heel portion and the sole portion of the user's sole are easily received by the elastic midsole, and the arch portion of the suspended state cannot be cushioned, so that the user's sole must naturally support the arch portion. And the soles of the feet are sore.

In order to keep the inside of the shoe dry and clean, the operator will place an insole above the elastic midsole. Some soles can be attached with a slightly elastic buffer layer on the bottom of the insole to further enhance the cushioning support inside the shoe. Such insoles still do not provide cushioning support to the user's arch.

The main purpose of the present invention is to provide a cushioning support structure in a shoe, which can mainly provide static support for the arch portion of the bottom of the human foot and a dynamic cushioning function, so that the user can walk or stand for a long time. There is no such thing as a sore foot.

In order to achieve the above object, the cushion support structure in the shoe provided by the present invention comprises a midsole, a foot arch, and an insole. The midsole has a high hardness and can support the arch pad. The arch pad is used to support the arch portion of the bottom of the human foot. The insole is useful for maintaining dryness and cleanliness within the shoe.

The midsole is provided with a rigid bottom plate, a slightly flexible intermediate layer, and an elastic upper layer. The upper layer, the middle layer and the bottom plate are integrated from top to bottom. The rigid base plate is of sufficient length to provide planar support to the arch pad without obstructing the bending of the midsole front end.

The arch pad is a high elastomer and is disposed above the midsole. The leading edge of the arch pad extends to the trailing edge of the foot portion and the trailing edge extends to support the heel portion. The top surface of the arch pad is provided with a ridge which can support the arch portion of the human foot.

The insole is disposed above the arch pad. The insole is glued to the arch pad. Moreover, the bottom of the insole is used to support the foot portion, and a soft buffer layer is adhered.

A hole is provided at a position of the midsole for supporting the foot portion. A buffer sheet is adhered to the through hole, and the buffer sheet has a buffering capacity higher than that of the upper layer having elasticity.

Please refer to Figure 1 to Figure 3. The cushioning support structure in the shoe disclosed in the present invention comprises a midsole 10, a foot arch 20, and an insole 30. The midsole 10 has a relatively high stiffness and is capable of supporting the arch pad 20. The insole 10 is in a soft form and is disposed above the midsole 10 and the arch pad 20 to facilitate drying and cleaning of the shoe.

The midsole 10 includes a rigid bottom plate 11, a slightly flexible intermediate layer 12, and an elastic upper layer 13. The upper layer 13, the intermediate layer 12, and the bottom plate 11 are integrally joined from top to bottom. The elasticity of the upper layer 13 of the midsole 10 is mainly to impart a cushioning ability to the midsole 10. The middle layer 12 of the midsole 10 serves mainly as an attachment member of the upper layer 13, so that the soft upper layer 13 is not deformed under long-term use. The bottom plate 11 of the midsole 10 has a leading edge extending to a rear edge capable of supporting the sole portion, and a trailing edge extending to a position capable of supporting the heel portion. The bottom plate 11 is a rigid plate body and is not flexible. Since the front edge of the bottom plate 11 is only located at the trailing edge of the foot portion, it does not affect the bending of the sole when the user walks.

The arch pad 20 is a high-elastic body which is made of a foamed material of higher density and has a high elastic supporting ability. Please refer to Figure 4 and Figure 5. The arch pad 20 is disposed above the midsole 10. The leading edge of the arch pad 20 extends to a rear edge capable of supporting the sole portion of the foot, and the trailing edge extends to a position capable of supporting the heel portion. The arch pad 20 can be supported by the bottom plate 11 of the midsole 10. The top of the arch pad 20 is provided with a ridge 21 which can support the human arch portion (not shown). By virtue of the hard nature of the bottom plate 11, when the archpad 20 is pressed by the user's arch recess, a superior cushioning support can be produced.

The insole 30 is disposed above the arch pad 20 to shield the arch pad 20. The insole 30 can be bonded to the arch pad 20 for convenience in use. While the insole 30 is placed within the shoe 40, the arch pad 20 is also placed at a set position within the shoe 40.

When the user wears the shoe 40 with the creative cushion support structure, the ridge portion of the top surface of the arch pad 20 can support the arch concave portion of the human foot, and provide support for the arch concave portion of the human foot. The human foot can be fully supported and cushioned, so that when the user walks for a long distance and stands for a long time, the sole of the foot will not be sore.

The insole 30 is soft and has low strength. In practice, a soft buffer layer 31 may be adhered to the bottom portion of the insole 30 for supporting the foot portion. The trailing edge of the soft cushion layer 31 and the leading edge of the arch pad 20 are spliced. The soft cushioning layer 31 can impart some cushioning effect to the user's foot.

Although the upper layer 11 of the midsole 10 has elasticity, it can absorb part of the reaction force of the ground feedback, but since the middle layer 12 of the midsole 10 still has a considerable degree of hardness, the ability of the midsole 10 to absorb the reaction force is limited. To this end, the midsole 10 can be provided with a perforation 14 at a position for supporting the foot portion, and the perforation 14 is stuffed with a cushion sheet 15. The buffer sheet 15 is more responsive to the ground feedback reaction, that is, the buffer sheet 15 has a higher buffering capacity than the midsole 10 elastic upper layer 11. When the user is walking, the sole of the foot is pressed against the cushion sheet 15, and a better cushioning effect can be obtained.

In summary, the cushion support structure in the shoe provided by the present invention can support the arch portion of the user's sole at the bottom of the foot, and at the same time, provide cushioning to the arch portion when the user walks and stands. The effect is that the user's sole will not be sore. phenomenon.

The above description is by way of a detailed description of the present invention, and is not intended to limit the scope of the present invention. Anyone who is familiar with such a skilled person can understand, and appropriate changes and adjustments will not lose the essence of this creation, and will not deviate from the spirit and scope of this creation.
