Claims
- 1. A replaceable golf shoe cleat comprising:
- (i) disc means, said disc means presenting an upper surface and an undersurface;
- (ii) attachment means associated with said upper surface and enabling the cleat to be removably secured to co-operating means of a shoe sole;
- (iii) a plurality of barb-forming elements arranged in a ring on said undersurface, each barb-forming element being aligned to project outwardly of said ring at an acute angle to said undersurface and including a free end portion presenting a ground-engaging barb, each said barb-forming element being resiliently deflectable to increase said angle between said element and said undersurface for increased penetration of said ground-engaging barb into penetrable ground whereby to increase resistance to sliding of the cleat in use over penetrable ground; and
- (iv) land means, said land means presenting surfaces raised from said undersurface within said ring of barb-forming elements, said land means comprising a plurality of ridge-forming blocks extending inwardly of the ring from positions adjacent to said barb-forming elements.
- 2. A cleat according to claim 1, wherein said barb-forming elements are moulded integrally with said disc means of an elastomeric material.
- 3. A cleat according to claim 1, wherein each said barb-forming element is of tapering form as viewed in a plane extending through said barb at said acute angle to said undersurface.
- 4. A cleat according to claim 1, wherein each barb-forming element includes a convergent free-end portion forming said barb which terminates at an edge, said edge extending tangentially of said ring.
- 5. A cleat according to claim 4, wherein each said free-end portion presents a flat ground-engaging bearing surface extending from said edge in a direction inwardly of said ring, said bearing surface being inclined towards said undersurface in said direction.
- 6. A cleat according to claim 1, wherein said attachment means is screw-threaded for engagement with screw-threaded co-operating means of a shoe sole.
- 7. A cleat according to claim 6, wherein said ring of barb-forming elements is arranged coaxially of said screw axis.
- 8. A cleat according to claim 7, wherein said barbs are aligned along chords to said ring, being all turned in the same direction from radial alignment whereby to discourage unscrewing of said cleat in use.
- 9. A golf shoe including a plurality of cleats according to claim 1.
- 10. A replaceable golf shoe cleat comprising:
- (i) disc means, said disc means presenting an upper surface and an undersurface;
- (ii) attachment means associated with said upper surface and enabling the cleat to be removably secured to co-operating means of a shoe sole;
- (iii) a plurality of barb-forming elements arranged in a ring on said undersurface, each barb-forming element being aligned to project outwardly of said ring at an acute angle to said undersurface and including a free end portion presenting a ground-engaging barb, each said barb-forming element being resiliently deflectable to increase said angle between said element and said undersurface for increased penetration of said ground-engaging barb into penetrable ground whereby to increase resistance to sliding of the cleat in use over penetrable ground; and
- (iv) a land means, said land means presenting surfaces raised from said undersurface within said ring of barb-forming elements and in which spaces between radially inner surfaces of said barb-forming elements and adjacent surfaces of said land means permit unimpeded deflection of the barb-forming elements.
- 11. A cleat according to claim 10, wherein said barb-forming elements are moulded integrally with said disc means of an elastomeric material.
- 12. A cleat according to claim 10, wherein each said barb-forming element is of tapering form as viewed in a plane extending through said barb at said acute angle to said undersurface.
- 13. A cleat according to claim 10, wherein each barb-forming element includes a convergent free end portion forming said barb which terminates at an edge, said edge extending tangentially of said ring.
- 14. A cleat according to claim 13, wherein each said free end portion presents a flat ground-engaging bearing surface extending from said edge in a direction inwardly of said ring, said bearing surface being inclined towards said undersurface in said direction.
- 15. A cleat according to claim 10, wherein said attachment means is screw-threaded for engagement with screw-threaded co-operating means of a shoe sole.
- 16. A cleat according to claim 15, wherein said ring of barb-forming elements is arranged coaxially of said screw axis.
- 17. A cleat according to claim 16, wherein said barbs are aligned along chords to said ring, being all turned in the same direction from radial alignment whereby to discourage unscrewing of said cleat in use.
- 18. A golf shoe including a plurality of cleats according to claim 10.
