Cushioning element for sports apparel
Improved cushioning elements for sports apparel, in particular for soles for sports shoes, are described. A cushioning element for sports apparel with a first deformation element is provided. The deformation element includes a plurality of randomly arranged particles of an expanded material, wherein there are first voids within the particles and/or between the particles.
1. A shoe sole comprising at least one cushioning element for sports apparel, the at least one cushioning element further comprising:
(a) a first deformation element comprising a plurality of randomly arranged particles of an expanded material;
(b) wherein there are first voids within the particles, between the particles, or both within and between the particles;
(c) wherein the first deformation element takes up a first partial region of the cushioning element and wherein the cushioning element further comprises a second deformation element comprising a plurality of randomly arranges particles of an expanded material;
(d) wherein there are second voids within the particles, between the particles, or both within and between the particles of the second deformation element, and wherein the second voids are smaller on average than the first voids of the first deformation element.
2. The shoe sole according to claim 1 , wherein the first voids form one or more channels through the first deformation element that are permeable to air and/or liquids.
3. The shoe sole according to claim 2 , further comprising a reinforcing element.
4. The shoe sole according to claim 3 , wherein the reinforcing element is a textile reinforcing element.
5. The shoe sole according to claim 3 , wherein the reinforcing element is a foil reinforcing element.
6. The shoe sole according to claim 5 , wherein the foil reinforcing element is air and/or liquid permeable in at least one direction.
7. The shoe sole according to claim 5 , wherein the foil reinforcing element is air permeable in one or both directions and liquid permeable only one direction.
8. The shoe sole according to claim 3 , wherein the reinforcing element is a fiber reinforcing element.
9. The shoe sole according to claim 3 , wherein the reinforcing element comprises at least one opening which is arranged in such a way that air and/or a liquid passing through the one or more channels in the first deformation element can pass in at least one direction through the at least one opening in the reinforcing element.
10. The shoe sole according to claim 3 , wherein the reinforcing element is a foil comprising thermoplastic urethane.
11. The shoe sole according to claim 3 , wherein the reinforcing element comprises at least one opening which is arranged in such a way that air and/or a liquid passing through the one or more channels in the first deformation element can pass in at least one direction through the at least one opening in the reinforcing element.
12. A shoe comprising at least one cushioning element for sports apparel, the at least one cushioning element comprising:
(a) a first deformation element comprising a plurality of randomly arranged particles of an expanded material;
(b) wherein there are first voids within the particles, between the particles, or both within and between the particles;
(c) wherein the first deformation element takes up a first partial region of the at least one cushioning element and wherein the at least one cushioning element further comprises a second deformation element comprising a plurality of randomly arranges particles of an expanded material;
(d) wherein there are second voids within the particles, between the particles, or both within and between the particles of the second deformation element, and wherein the second voids are smaller on average than the first voids of the first deformation element; and
(e) wherein the at least one cushioning element is provided as at least a part of a sole of the shoe.
13. The shoe sole according to claim 1 , wherein the randomly arranged particles of an expanded material in the first deformation element, in the second deformation element, or in both the first deformation element and the second deformation element comprise one or more of the following cross-sectional profiles: ring-shaped, oval, square, polygonal, round, rectangular, and star-shaped.
