All bladders were pressurized at the same internal pressure. The volume of each bladder is at least different from the volume of the other bladder such that each bladder provides a different resistance than the resistance produced by at least one bladder having a different volume. The bladder formed on the forefoot support is pressurized at a first internal pressure and the bladder formed on the heel support is pressurized at a second internal pressure, the first and second internal pressures being different. All of the cells are closed so that the fluid cannot flow between the cells. A bladder for a shoe comprised of an elastomeric material, comprising: a body; a closing wall formed on the body, said closing wall forming at least one side; and pockets formed in the body, the pockets being filled with a fluid such that each pocket is pressurized to a selected internal pressure, each pocket including a raised support portion to provide elastic resistance, and a relatively narrow channel portion having an open end in communication with its corresponding support portion and a closed end, all closed ends being connected to at least one side of the closure wall.

Detailed Description

In order to further explain the technical scheme of the utility model, the following is explained in detail through specific examples.

The novel elastic member of the present utility model, as shown in fig. 1 to 8, comprises a container 11 deformable and having a containing cavity 111, and a plastically deformable inner deformation member 12 contained in the container 11. In the practical use process, the utility model utilizes the plastic deformation performance of the inner deformation piece 12 to adapt to the pressure surface of the sole of a human body, provides corresponding softness and large-area fitting and matching support, improves comfort, and on the basis, when the inner deformation piece 12 is a non-Newtonian fluid foaming material, the inner deformation piece 12 is distributed in a dispersed phase by utilizing the non-Newtonian fluid effect of the inner deformation piece 12 when receiving shearing force or impact force, and can generate instant elastic support, thereby meeting the elastic requirement required by the human body, having an assisted bouncing effect, and meanwhile, the container 11 utilizes the deformation and space limitation of the container to restrict the inner deformation piece 12, thereby ensuring the shape and maintenance performance of the inner deformation piece 12. For slow and small force, the inner deformation piece 12 generates small deformation to buffer, and the shape is quickly restored by the constraint of the containing piece 11, and the elastic buffer can be generated by the containing piece 11; for rapid impact forces, the inner deforming member 12 directly uses the dispersed phase to create a repulsive force. The container 11 also protects the inner deformation 12.

Preferably, the inner deforming member 12 is a plastic foam material. The plastic foaming material utilizes the inner micro-pores to enhance the flexibility, elastic buffering and rebound performance, and the uniformly distributed micro-pores can enhance the uniformity of the effect, obviously reduce the overall density of the material and effectively play the performance of the material in unit volume.

Preferably, the inner deformation 12 is foam molded from a non-newtonian fluid. Non-newtonian fluids refer to fluids that do not satisfy newtonian viscosity laws of experiment, i.e., fluids whose shear stress and shear strain rate are not linear. Such as polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, terylene, rubber, various engineering plastics, melt of chemical fiber, and other various materials. Then, the foaming agent is added into the non-Newtonian fluid by adopting the prior foaming technology, for example, after the foaming microspheres are added, the non-Newtonian fluid foaming material can be manufactured under the corresponding foaming condition. The non-Newtonian fluid after foaming molding can exist in the form of fluid, solid or semisolid (fluidity or aggregation is between the liquid and the solid), further has flexibility under common lasting pressure and is distributed in a dispersed phase when being subjected to shearing force or impact force, and can generate instant elastic supporting performance, thereby having an assisted bouncing effect. The semi-solid foaming molding material can realize shaping, and also has the characteristic of realizing automatic fusion repair and maintaining the whole after being broken by high-strength impact. The inner deformation 12 may be foam molded from viscoelastic fluids, shear thickening fluids, and/or thixotropic fluids. Viscoelastic fluids such as polyacrylamide; shear thickening fluids such as thick suspensions, proteins and certain high molecular weight concentrated solutions; thixotropic fluids such as aged gums, sols, clay suspensions, high polymer liquids or solutions.

To achieve the aforementioned properties, the inner deforming member 12 is preferably fluid, solid or semi-solid. Solid and semi-solid are easily shaped and easily mounted with the container 11; for the inner deformation member 12 in the fluid form, the shaping can be achieved by filling the inner deformation member 12 in the fluid form into the accommodating cavity 111 after shaping the accommodating cavity 111.

The structure can better utilize the deformation and space limitation of the container 11 to restrain the inner deformation member 12, ensure the inner deformation member 12 to keep shape and maintain performance, avoid that the shape and performance of the inner deformation member 12 cannot be restrained due to excessive gas in the container cavity 111, and also interfere the performance of the inner deformation member 12 due to the space transformation of the gas.

Preferably, the holding cavity 111 is a closed space. The accommodating cavity 111 in the form of a closed space can effectively protect the inner deformation piece 12, avoid the damage of external substances to the inner deformation piece 12, and prevent the inner deformation piece 12 from being extruded out of the accommodating cavity 111, so as to ensure the lasting and stable performance of the inner deformation piece 12.
