Description

Hollow objects forming curved surfaces and combinations thereof

The invention is related to the sole structure; in particular, it refers to a hollow object capable of forming a curved surface and a combination of the hollow objects used for making the sole structure.

The general shoe sole structure is usually made of foam material through injection molding. However, due to the limited injection molding mold structure, the general shoe sole structure can only have a fixed curved surface, and the curvature of the curved surface of the shoe sole structure cannot be adjusted according to the needs of users.

For example, since the general sole structure is a fixed curved surface, when the user needs to adjust the curvature of the sole structure, the user can only use an additional insole with the required curvature to line the existing sole structure. To meet the user's demand for the curvature of the sole structure.

In addition, the existing inflatable air-cushion sole structure, like the above-mentioned general foam sole structure, only has a fixed curved surface, and users cannot adjust the curvature of the curved surface of the air-cushion sole structure according to requirements. Therefore, when the user needs to adjust the curvature of the air-cushioned sole structure, the user can only use an additional insole with the required curvature to line the existing air-cushioned sole structure to satisfy the user's requirements for the curvature of the air-cushioned sole structure. demand.

In summary, since the existing general sole structure and air-cushion sole structure cannot adjust the curvature of the sole structure according to the needs of users, there is an urgent need for a novel hollow object that can form a curved surface for making sole structures, so as to facilitate use. according to demand Adjust the surface curvature of the hollow object, thereby meeting the user's requirements for the surface curvature of the sole structure.

In view of this, the object of the present invention is to provide a hollow object forming a curved surface and a hollow object combination thereof, which can be used for making a shoe sole structure. The hollow object provided by the present invention can be injected with fluid, and the hollow object can form a hollow structure with a curved surface by combining with a curved plate with a preset curvature, and the elasticity and hardness of the hollow object can be further regulated by using the amount of injected fluid.

In order to achieve the above object, a hollow object provided by the present invention is composed of an upper surface, a lower surface and a side surface, including at least one hollow unit, a curved panel with a predetermined curvature, and each of the hollow units and the adjacent adjacent At least one other of the hollow units constitutes a hollow structure with a curved surface; the hollow object includes a plurality of hollow units, the hollow units can be controlled to be filled with fluid and expand, and each of the hollow units and at least another of the hollow units One is directly adjacent, and when each of the hollow units is filled with fluid and expands, the elasticity and hardness of the hollow object can be further regulated; the hollow object system is used to make a sole of a shoe, wherein the hollow as the sole Each of the hollow units in the object extends along a first direction from a heel of the sole to the sole of the foot, and each of the hollow units is arranged parallel to each other along a second direction perpendicular to the first direction, so that A sole structure capable of continuous transmission is formed.

Another object of the present invention is to provide a combination of hollow objects, including a plurality of hollow objects as described above, any two of these hollow objects are adjacent to each other, but these hollow objects are not connected to each other, when these hollow objects are respectively When filled with fluid and bent, the curved surfaces of the hollow objects have one or more curvatures; the hollow objects are used to make a sole of a shoe, wherein the hollow units in the hollow objects of the sole are Department along the A heel portion of the sole extends toward a first direction of the sole portion, and the hollow units are arranged parallel to each other along a second direction perpendicular to the first direction to form a sole structure capable of continuous transmission.

The effect of the present invention is that the hollow object provided by the present invention can be combined with a curved plate with a predetermined curvature to make the hollow object form a curved surface, and the elasticity and hardness of the hollow object can be further regulated by using the amount of injected fluid. Accordingly, when the hollow object provided by the present invention is used to make a shoe sole structure, the user can adjust the curvature of the hollow object as required, and then adjust the curvature of the manufactured shoe sole structure. When the user wears the footwear made of the hollow object as the sole, the curved surface structure formed by the hollow object will produce a rolling-like motion during the user's walking. For example, when a user walks, the hollow units of the hollow object will sequentially contact or approach the ground, producing an effect similar to that of the tire block when the tire is rolling, and the rebound force generated by the compression of the hollow object will Because the center point of curvature moves forward (refer to Figure 12), an eccentric moment is generated, which in turn has an effect on the sole of the shoe. Therefore, the rolling-like motion produced by the hollow object is used, for example, when a tire rolls, by the eccentric moment generated. The principle of generating rolling torque to the tires can effectively reduce the frictional resistance when the user walks, thereby providing the user with a lighter and labor-saving walking experience.
