Abstract
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. The height above the receptacle base of at least a portion of each tooth in the first set of teeth is less than the height of the second set of teeth above the base. The result is that cleat splines pass in turn over a corresponding tooth of less than full height and then a full tooth upon insertion and rotation. The cleat spline's interaction with the edge of a second tooth of less than full height in the receptacle impedes further rotation of cleat with respect to receptacle. The reduced height of the first tooth ensures that the user only experiences interference from the cleat's splines to a full height annulus tooth, providing a single click engagement system. Thus, the user obtains positive feedback that the cleat and socket have mated correctly.
