Description
Technical Field
The present invention relates to a sole structure; in particular to a hollow object which can form a curved surface and is used for manufacturing a sole structure.
Background
The conventional sole structure is usually made of foam material through injection molding, but is limited to the injection molding mold structure, and the conventional sole structure only has a fixed curved surface, and the curvature of the curved surface of the sole structure cannot be adjusted according to the user's requirement.
For example, since the sole structure is a fixed curved surface, when a user needs to adjust the curvature of the curved surface of the sole structure, the user can only set up an additional insole having the desired curvature on the existing sole structure to meet the user's requirement for the curvature of the curved surface of the sole structure.
In addition, the existing inflatable air cushion sole structure is also the same as the above-mentioned common foaming sole structure, and only has a fixed curved surface, so that the user can not adjust the curvature of the curved surface of the air cushion sole structure according to the requirement. Therefore, when the user needs to adjust the curvature of the curved surface of the air cushion sole structure, the user can only line up the existing air cushion sole structure through the additional insole with the required curvature of the curved surface so as to meet the requirement of the user on the curvature of the curved surface of the air cushion sole structure.
In summary, because the conventional sole structure and the air cushion sole structure cannot adjust the curvature of the curved surface of the sole structure according to the needs of the user, there is a need for a novel hollow object capable of forming a curved surface for manufacturing the sole structure, so that the user can adjust the curvature of the curved surface of the hollow object according to the needs, and the user's needs for the curvature of the curved surface of the sole structure can be satisfied.
Disclosure of Invention
Accordingly, it is an object of the present invention to provide a curved hollow object that can be used to fabricate a sole structure. The hollow object provided by the invention can be injected with fluid, the hollow object forms a hollow structure with a curved surface by combining with a curved plate with a preset curvature, and the elasticity and the hardness of the hollow object can be further regulated and controlled by using the quantity of the injected fluid.
The present invention provides a hollow object, which comprises an upper surface, a lower surface and a side surface, and comprises at least one hollow unit, a curved plate with a predetermined curvature, and at least one other hollow unit of the plurality of hollow units adjacent to the curved plate, wherein the curved plate and the at least one other hollow unit form a hollow structure with a curved surface; the hollow object comprises a plurality of hollow cells operable to be filled with a fluid and expanded, each of the hollow cells being in direct abutment with at least one other of the plurality of hollow cells, the elasticity and stiffness of the hollow object being further controllable when each of the hollow cells is filled with the fluid and expanded; the hollow object system is used for manufacturing a sole part of a shoe sole, wherein each hollow unit in the hollow object as the sole part extends along a heel part of the shoe sole to a first direction of the sole part, and each hollow unit is arranged in parallel along a second direction perpendicular to the first direction, so that a shoe sole structure capable of continuous transmission is formed.
Another object of the present invention is to provide a hollow object assembly, comprising a plurality of hollow objects as described above, wherein any two of the plurality of hollow objects are adjacent to each other, but the plurality of hollow objects are not communicated with each other, and when the plurality of hollow objects are respectively filled with fluid and bent, the curved surfaces of the plurality of hollow objects have one or more curved surface curvatures; the hollow object system is used for manufacturing a sole part of a shoe sole, wherein each hollow unit in the hollow object as the sole part extends along a heel part of the shoe sole to a first direction of the sole part, and each hollow unit is arranged in parallel along a second direction perpendicular to the first direction, so that a shoe sole structure capable of continuous transmission is formed.
The hollow object provided by the invention can be combined with a curved plate with a preset curvature to form a curved surface, and the elasticity and hardness of the hollow object can be further regulated and controlled by the quantity of injected fluid. Therefore, when the hollow object provided by the invention is used for manufacturing the sole structure, a user can adjust the curvature of the curved surface of the hollow object according to the requirement, and further adjust the curvature of the curved surface of the manufactured sole structure. When a user wears the shoes made of the hollow objects as the soles, the curved surface structure formed by the hollow objects can generate a rolling motion mode in the walking process of the user. For example, when a user walks, the hollow units of the hollow objects sequentially contact or approach the ground, and generate an effect similar to the contact between the blocks of the tire and the ground when the tire rolls, and the rebound force generated by the compressed hollow objects generates an eccentric moment due to the forward movement of the curvature center point (see fig. 12), thereby generating a forward propulsion effect on the sole.

In fig. 1, a hollow object 1a includes a plurality of hollow units 12, 14, 16, 18 for forming a curved surface. A plurality of hollow cells 12, 14, 16, 18 being controllably filled with a fluid and expanded, each of the hollow cells 12, 14, 16, 18 being in direct abutment with at least one other of the plurality of hollow cells 12, 14, 16, 18; for example, the hollow cells 12 are directly adjacent to the hollow cells 14, the hollow cells 14 are directly adjacent to the hollow cells 16, and the hollow cells 16 are directly adjacent to the hollow cells 18. In the first embodiment of the present invention, the fluid may be, for example, a gas or a liquid.
When each of the hollow cells 12, 14, 16, 18 is filled with a fluid and expanded, each of the hollow cells 12, 14, 16, 18 and at least another one of the plurality of adjacent hollow cells 12, 14, 16, 18 form the curved surface, as shown in fig. 2.
In the first embodiment of the present invention, before each of the hollow cells 12, 14, 16, 18 is filled with the fluid and expanded, each of the hollow cells 12, 14, 16, 18 and at least one other of the adjacent hollow cells 12, 14, 16, 18 form a flat surface, as shown in fig. 1.
In the first embodiment of the present invention, each of the plurality of hollow cells 12, 14, 16, 18 is a polyhedron. Taking the polyhedrons 14 and 16 as an example, the polyhedrons 14 and 16 have a bearing surface 142 and 162, and the bearing surface 142 of the polyhedron 14 is directly adjacent to the bearing surface 162 of at least one other polyhedron 16, so that when each polyhedron 14 and 16 is filled with fluid and expands, the included angle between the bearing surface 142 of the polyhedron 14 and the bearing surface 162 of at least one other polyhedron 16 adjacent thereto is reduced (θ 2< θ 1) to form the curved surface.
As shown in fig. 1, before each of the polyhedrons 14, 16 is filled with fluid and expanded, the bearing surface 142 of the polyhedron 14 has the largest included angle θ 1 with the bearing surface 162 of at least another one 16 of the adjacent polyhedrons, and constitutes a flat surface. In the first embodiment of the present invention, the maximum included angle θ 1 is a flat angle (180 °).
As shown in fig. 1 and 2, the polyhedrons 14 have at least one abutting surface 144 adjacent to the bearing surface 142, the polyhedrons 16 have at least one abutting surface 164 adjacent to the bearing surface 162, and when the bearing surface 142 of each of the polyhedrons 14 is directly adjacent to the bearing surface 162 of at least another one 16 of the polyhedrons, the abutting surfaces 144 and 164 of the polyhedrons 14 and at least another one 16 of the polyhedrons are in face-to-face and direct contact with each other. When each polyhedron 14 and 16 is filled with fluid and expands, the pushing surface 144 of the polyhedron 14 and the pushing surface 164 of at least one other polyhedron 16 adjacent to each other are oppositely pushed, so that the two bearing surfaces 142 and 162 form a smaller included angle theta 2; in detail, when each polyhedron 14, 16 is filled with fluid and expands, the junction of the two bearing surfaces 142, 162 adjacent to each other is used as a pivot axis of the polyhedron 14, 16, so that the included angle between the two bearing surfaces is reduced (θ 2< θ 1) to form the curved surface.
In the first embodiment of the present invention, one of the plurality of hollow cells 18 has a filling hole 11, the filling hole 11 is used for filling fluid into the hollow cell 18, and the hollow cells 12, 14, 16, 18 are communicated with each other. When each of the hollow cells 12, 14, 16, 18 is filled with a fluid, the same fluid pressure is present within each of the hollow cells 12, 14, 16, 18. In other words, if the configurations of the hollow units 12, 14, 16, 18 are identical and the hollow units 12, 14, 16, 18 are expanded by filling fluid, the angles between the bearing surfaces of the hollow units 12 and 14, the angles between the bearing surfaces of the hollow units 14 and 16, and the angles between the bearing surfaces of the hollow units 16 and 18 will be substantially the same.
Referring to fig. 3, fig. 3 is a schematic side view of a hollow object 1C according to a first embodiment of the present invention, wherein the hollow object 1C is filled with a fluid and attached to a curved surface C to form a curved surface. The hollow object 1c has a plurality of hollow cells, of which hollow cells 14, 16 are exemplified. In fig. 3, the hollow object 1C is attached to the curved surface C after being filled with the fluid, thereby generating a curved surface, wherein the pushing surface 144 of the hollow unit 14 and the pushing surface 164 of the hollow unit 16 face each other and do not push against each other; the curved body C may be, for example, a rigid curved plate, such as a carbon fiber composite curved plate. In the embodiment of the present invention, the hollow object 1C may be attached to the curved surface C first, and then the hollow object 1C is filled with the fluid after the curved surface is generated. It should be noted that when the hollow units 14 and 16 are pressed by an external force (such as a foot treading force), the hollow units 14 and 16 are deformed by the pressing, and the pushing surface 144 of the hollow unit 14 and the pushing surface 164 of the hollow unit 16 push against each other to form a curved supporting structure with a buffering function, so as to support and reinforce the curved body C, thereby improving the mechanical properties of the whole hollow object 1C.
