Footwear cleat with blade-like traction elements
View Patent ↗A shoe cleat comprises a fan-like array of dynamic traction elements that, under the weight of a wearer of a shoe, resiliently deflect toward the cleat hub and are compressed against an adjacent traction element and/or the hub to trap interposed grass blades.
1. A cleat securable to the sole of a shoe for providing traction for the shoe on a ground surface, the cleat comprising:
a hub having a longitudinal axis oriented perpendicular to the hub and vertically when the sole of the shoe is on the ground, said hub having an exposed bottom surface facing away from the shoe sole when the cleat is secured to the shoe;
a plurality of blade-like traction elements extending in angularly spaced relation in a generally radial fan-like array along the bottom surface of the hub with a bottom edge of each element projecting downwardly from the hub; and
a cleat connector member provided in an upper surface of the hub facing oppositely of the exposed bottom surface, wherein said connector is securable to a shoe connector member;
wherein each traction element includes:
a fixed edge extending generally radially along and secured to said bottom surface of said hub;
a dynamic edge disposed transversely opposite the fixed edge and spaced from said bottom surface of said hub; and
a distal edge disposed proximate the hub periphery and extending between said dynamic and fixed edges,
wherein said dynamic and fixed edges are substantially longer than said distal edge,
wherein said dynamic edge is skewed relative to said fixed edge so as to not be coplanar with said fixed edge,
and wherein said dynamic edge is flexibly resiliently movable relative to said fixed edge and said hub.
2. The cleat of claim 1 wherein at least a portion of one of said traction elements overlies at least a portion a second adjacent traction element when viewed along side axis.
3. The cleat of claim 1 , wherein said traction elements include plural resiliently deflectable dynamic traction elements each configured to overlie an adjacent element and to be deflectable toward the hub so that, when deflected, the deflected traction element engages and traps blades of grass between itself and an adjacent dynamic traction element and between itself and the hub.
4. A cleat securable to the sole of a shoe for providing traction for the shoe on a ground surface, the cleat comprising:
a hub having a longitudinal axis oriented perpendicular to the hub and vertically when the sole of the shoe is on the ground, said hub having an exposed bottom surface facing away from the shoe sole when the cleat is secured to the shoe;
a plurality of blade-like traction elements extending in angularly spaced relation in a generally radial fan-like array along the bottom surface of the hub with a bottom longitudinal edge of each element projecting downwardly from the hub; and
a cleat connector member provided in an upper surface of the hub facing oppositely of the exposed bottom surface, wherein said connector is securable to a shoe connector member;
wherein said traction elements include plural resiliently deflectable dynamic traction elements each configured to overlie an adjacent element and to be deflectable toward the hub so that, when deflected, the deflected traction element is compressed against an adjacent traction element and traps blades of grass between itself and said adjacent dynamic traction.
5. The cleat of claim 1 , wherein said traction elements include plural resiliently deflectable dynamic traction elements each configured to be deflectable toward the hub so that, when deflected, the deflected traction element is compressed against the hub and traps blades of grass between itself the hub.
6. The cleat of claim 1 , wherein each traction element is a resiliently deflectable traction element and has a twisted non-planar configuration.
7. The cleat of claim 6 , wherein each traction element extends generally radially from a location proximate said axis and terminates distally proximate the periphery of said hub.
8. The cleat of claim 7 wherein each traction element includes proximal and distal edges extending between the fixed and bottom longitudinal edges, wherein said proximal edge is shorter than said distal edge.
9. The cleat of claim 8 , further comprising a boss secured to said bottom surface of said hub proximate said axis, and wherein said proximal edge is secured to said boss.
10. A cleat securable to the sole of a shoe for providing traction for the shoe on a ground surface, the cleat comprising:
a hub having a longitudinal axis oriented perpendicular to the hub and vertically when the sole of the shoe is on the ground, said hub having an exposed bottom surface facing away from the shoe sole when the cleat is secured to the shoe;
a plurality of blade-like torsionally-twisted and resiliently flexible traction elements extending in angularly spaced relation in a generally radial fan-like array along the bottom surface of the hub with an elongated edge of each element projecting downwardly from the hub; and
a cleat connector member provided in an upper surface of the hub facing oppositely of the exposed bottom surface, wherein said connector is securable to a shoe connector member;
wherein each traction element is configured to overlie an adjacent element and to be deflectable toward the hub so that, when deflected, the deflected traction element is compressed against an adjacent traction element and traps blades of grass between itself and said adjacent dynamic traction.
