Abstract

Describes are support elements for a sole of a shoe, in particular a sports shoe, a sole and a shoe with such a support element, as well as a method for the manufacture of a support element. As examples, the support element includes a first partial member formed of a first material, and a second partial member formed of a second material. The first partial member is mechanically joined to the second partial member in a connection region, wherein the connection region is configured to allow the first partial member to rotate or slide relative to the second partial member. The first partial member, the second partial member, and the connection region can be co-molded and joined together in a single fabricating step.

First claim

That which is claimed is:

1 . A sports shoe comprising an upper and a cushioning element;
wherein the shoe encloses a foot of a wearer; and wherein the cushioning element comprises a support element for a shoe, the support element comprising:
a. a first partial member comprising a first plastic material; and
b. a second partial member comprising a second plastic material;
wherein the support element is completely enclosed in the cushioning element; wherein the first plastic material is different than the second plastic material; wherein the second partial member is connected rotatably with the first partial member in a connection region; and wherein at least one of the following is met: i. the first partial member and a plurality of second partial members form the support element; ii. the second partial member and a plurality of first partial members form the support element with a skeleton structure; iii. a plurality of first partial members and a plurality of second partial members are alternatingly connected to each other rotatably forming the support element.

2 . The sports shoe according to claim 1 , wherein the second partial member is connected rotatably with the first partial member in the connection region.

3 . The sports shoe according to claim 1 , wherein the first partial member and a plurality of second partial members form the support element.

4 . The sports shoe according to claim 1 , wherein the second partial member and a plurality of first partial members form the support element with a skeleton-like structure.

5 . The sports shoe according to claim 1 , wherein a plurality of first partial members and a plurality of second partial members are alternatingly connected to each other rotatably in a plurality of connection regions, forming the support element.

6 . The sports shoe according to claim 1 , wherein the first plastic material and the second plastic material are chosen such that the connection region does not comprise a chemical bond between the two materials.

7 . The sports shoe according to claim 6 , wherein the first plastic material and the second plastic material are chemically incompatible.

8 . The sports shoe according to claim 6 , wherein the first plastic material has a first melting temperature that is higher than a second melting temperature of the second plastic material.

9 . The sports shoe according to claim 6 , wherein the first plastic material and the second plastic material do not form a chemical bond due to an additive contained in either or both of the first and/or second plastic material.

10 . The sports shoe according to claim 6 , wherein the first plastic material and the second plastic material each comprise one or more of the following materials: polyamide, polytetrafluoroethylene, and combinations thereof.

11 . The sports shoe according to claim 1 , wherein a connection region is provided as one of the following:
(a) as a ball joint, or (b) a piston and a cylinder, in which cylinder the piston is arranged.
