The present application claims the priority of Chinese Patent Application No. 202222397465.8 filed on Sep. 9, 2022, with the title “A SHOCK-ABSORBING AND POWER-ASSISTED SHOE SOLE WITH ENHANCED STABILITY”. The disclosure of the above application is incorporated herein by reference in its entirety.
The application relates to the field of shoe sole technology, in particular to the cushioning-boosting shoe sole with enhanced stability.
A shoe sole includes midsole and outsole. The outsole is the part where the shoe comes into contacting with the ground, simply put, the material of the outsole is made of natural rubber or artificial synthetic rubber. The materials commonly used in the midsole include PHYLON, EVA, TPU, etc., which have the advantages of pressure resistance, lightweight, and good elasticity. With people's increasing demand for the cushioning performance of shoe soles, it is obvious that the demand cannot be met by relying solely on the physical properties of materials.
The Chinese utility model with authorization announcement number CN204132549U disclosed a boosting-cushioning shoe sole, wherein the boosting-cushioning layer includes many springs and a air cushion; the springs are placed at the position corresponding to the foot sole and between the upper layer and a middle layer, the air cushion is placed at the position corresponding to the foot heel and supporting between the upper layer and a middle layer; the upper layer and the middle layer are respectively provided with positioning clips corresponding to the springs at the corresponding positions. The shoe sole provides power assistance through the elasticity of the spring, providing shock absorbing and buffering, but there are still shortcomings in this type of shoe sole, the shoe sole needs to be assembled with many springs, which is difficult to do, and the operation is quite complicate, resulting in low production efficiency; after using the shoe sole for a period of time, the springs are easy to rust and damage, leading to the loss of its elasticity, resulting in a sharp decrease in the shock absorbing performance of the shoe sole and inconvenience in use.
The application provides a cushioning-boosting shoe sole with enhanced stability in order to overcome the above-mentioned problems of the shoe sole, such as, difficult assembly, low production efficiency, and easy to rust and damage.
The application adopts the following technical programs:
A cushioning-boosting shoe sole with enhanced stability includes a midsole, and a cushioning-boosting component is sandwiched in middle of the midsole, the cushioning-boosting component is provided with a cavity inside, and a plurality of boosting elements are connected between the upper wall of the cavity and the lower wall of the cavity.
Furthermore, the midsole includes a midsole upper layer and a midsole lower layer, and a toe end of the midsole upper layer is adhered with a toe end of the midsole lower layer.
Furthermore, the midsole lower layer is adhered with an outsole.
Furthermore, the cushioning-boosting component is in a U-shaped shape, and both the above-mentioned midsole lower layer and the above-mentioned outsole are provided with a through-hole corresponding to the cushioning-boosting component.
Furthermore, the cross-section of boosting element is in the shape of the slash/slant or “<”(fold line) or fishbone.
Furthermore, the material of the midsole is MD (Molded EVA) or ETPU (Expanded thermoplastic polyurethane).
Furthermore, the material of the outsole is rubber or GPU (Thermosetting cast polyurethane elastomer).
Furthermore, the material of the cushioning-boosting component is TPU (Thermoplastic Polyurethane), and the material of the cushioning-boosting component is sandwiched between the midsole upper layer and the midsole lower layer.
The present application also provides a shoe comprising any of the above mentioned cushioning-boosting shoe sole with enhanced stability.
From the above descriptions of the structure of the application, it can be seen that compared with prior art, the present application has the following advantages:
The attached drawing reference signs: midsole 1, outsole 2, cushioning-boosting component 3, upper layer of the midsole 11, lower layer of the midsole 12, through-hole 20, cavity 30, boosting elements 31.
The specific examples of this application are explained below with reference to the attached drawings.
