Cleat attachment system
View Patent ↗A traction cleat attachment system for footwear that engages with a single click. The system comprises a cleat and a receptacle. The cleat includes a central stud with screw threads spaced about the outside surface of the stud. The receptacle includes a threaded annulus on a base for receiving the central stud of the cleat. The cleat also includes a collar coaxially surrounding the central stud with splines projecting from the interior collar surface. The threaded receptacle annulus is surrounded by two sets of alternating teeth projecting from the outside surface of the annulus. One of the set of alternating teeth have an upper surface at an angle with the base. Thus, the user obtains positive feedback that the cleat and socket have mated correctly.
1. A system for attaching a removable cleat to an athletic shoe, the system comprising:
a receptacle base;
an annulus extending from the receptacle base and having inner and outer surfaces, the inner surface having defined thereon a plurality of equally spaced helical surfaces adapted to receive screw threads;
a plurality of radial projections extending outwardly from the annulus's outer surface;
a cleat base;
a central stud projecting from the cleat base and disposed about a central axis, about which the cleat may be rotated for insertion into the receptacle, the central stud having an end distal from the cleat base and having an outer peripheral surface;
a plurality of screw threads spaced around and on the outer peripheral surface of the central stud, each screw thread having an outer helical surface;
a plurality of resiliently deflectable locking projections surrounding the stud and projecting inwardly; and
a cylinder disposed around the locking projections and concentrically about the central axis,
the distal end of the stud being less than 4 mm from the base.
2. The system according to claim 1 , wherein the cleat is configured to be connected to and locked to the receptacle with a turn of less than 70° around the central axis.
3. The system according to claim 1 , wherein the receptacle permits the cleat to be connected to and locked with a turn of less than 70° around the central axis.
4. The system according to claim 1 , wherein the receptacle has a height of less than 5 mm.
5. The system according to claim 1 , wherein the distal end of the stud extends less than 2.5 mm beyond the distance that each locking projection extends from the surface of the base adjacent to the locking projection.
6. The system according to claim 1 , wherein the locking projections extend less than 2 mm from the base.
7. The system according to claim 1 , wherein the distal end of the stud is between 2.5 mm and 4 mm from the base.
