Cleats and footwear for providing customized traction
View Patent ↗A removable cleat includes a plurality of projections, dividing into sets, with each set of projections made of different materials. The cleat includes a coupling element, for attachment to a shoe, and a ground contacting element. The ground contacting element contains a plurality of projections, with the projections divided into at least two sets. The projections may be disposed about the perimeter of the ground contacting element, such that each set of projections does not extend more than half the perimeter. Additionally, some of the plurality of projections may be located interior to the perimeter. Further, each set of projections may be oriented in a particular direction with respect to a plane formed by the perimeter. Each interspersed set of projections may be made of a different material, or each projection may itself be made of a different material.
1. A removable cleat comprising:
a coupling element; and
a ground-engaging element having
a base with a rim, the rim having a downward protrusion extending from the base to a bottom-most surface, and
a plurality of flexible projections, each of the flexible projections being outwardly and downwardly angled and being sufficiently thin to permit bending, each of the flexible projections having a central end and an outer end, the central end being connected to the base,
wherein a gap is maintained between the outer end and the rim's downward protrusion when the flexible projections are not bent toward the base,
wherein the central end of each of the flexible projections contacts the base at a first point above the bottom-most surface of the downward protrusion, and
wherein each of the flexible projections bends in a manner for the outer end to contact the base at a second point above the bottom-most surface when engaged against the ground.
2. A removable cleat according to claim 1 , wherein the rim's downward protrusion and the plurality of flexible projections are made of two different materials.
3. A removable cleat according to claim 2 , wherein the two different materials have different hardness.
4. A removable cleat according to claim 1 , wherein the flexible projections extend outwardly and downwardly angled in a radial manner.
5. A removable cleat according to claim 1 , further comprising a downwardly extending central projection.
6. A shoe comprising at least one cleat according to one of claims 1 - 3 and 4 - 5 .
7. A ground-engaging element of a cleat, the ground engaging element comprising:
a base;
a downwardly protruding rim connected to the base and protruding to a bottom-most surface; and
a plurality of flexible projections, each of the flexible projections being outwardly and downwardly angled and being sufficiently thin to permit bending, each of the flexible projections having an central end and an outer end, the central end connected to the base,
wherein a gap is maintained between the outer end and the downwardly protruding rim when the flexible projections are not bent toward the base,
wherein the central end of each of the flexible projections contacts the base at a first point above the bottom-most surface of the downwardly protruding rim, and
wherein each of the flexible projections bends in a manner for the outer end to contact the base at a second point above the bottom-most surface of the downwardly protruding rim when engaged against the ground.
8. A ground-engaging element according to claim 7 , wherein the rim and the plurality of flexible projections are made of two different materials.
9. A ground-engaging element according to claim 8 , wherein the two different materials have different hardness.
10. A ground-engaging element according to claim 7 , wherein the flexible projections extend downwardly and radially outward.
11. A shoe comprising at least one removable cleat having a ground-engaging element according to one of claims 7 - 9 and 10 .
12. A removable cleat comprising:
coupling means for coupling the cleat to a shoe; and
traction means, attached to the coupling means, for engaging the ground, the traction means having
a base,
a rim connected to the base and having a downward protrusion extending to a bottom-most surface, and
a plurality of flexible projections, each of the flexible projections being outwardly and downwardly angled and being sufficiently thin to permit bending, each of the flexible projections having a central end and an outer end, the central end being connected to the base,
wherein a gap is maintained between the outer end and the rim when the flexible projections are not bent towards the base,
wherein the central end of each of the flexible projection contacts the base at a first point above the bottom-most surface of the downward protrusion, and
wherein each of the flexible projections bends in a manner for the outer end to contact the base at a second point above the bottom-most surface of the downward protrusion when engaged against the ground.
13. A removable cleat according to claim 12 , wherein the flexible projections extend outwardly and downwardly angled in a radial manner.
14. A removable cleat according to claim 13 , wherein the rim's downward protrusion and the plurality of flexible projections are made of two different materials.
15. A removable cleat according to claim 14 , wherein the two different materials have different hardness.
16. A shoe comprising at least one cleat according to one of claims 12 and 13 - 15 .
