Title:
ROTATING PIVOT FOR SHOE
Document Type and Number:
WIPO Patent Application WO2004026061
Kind Code:
A3
Abstract:
A shoe sole (100) includes a rotatable pivot assembly (200) to allow easy pivoting of a ball region of a shoe. The shoe sole (100) includes a pivot cavity defined by an upper plate support surface (250) and a lower plate support surface (260) having an aperture (295) therein. A rotatable pivot assembly (200) includes a pivot plate (230) and a sole element (210) attached thereto. The pivot plate (230) is pivotally constrained within the pivot cavity and the sole element (210) extends through the aperture (295) in the pivot cavity to define an exterior contact surface. Preferably contacting surfaces of the pivot plate (230) and upper plate support surface (250) are formed of a low coefficient of friction material to allow easy rotation of the pivot plate (230) within the cavity. Because the assembly can be made thin with minimal parts, it results in a structure that substantially retains the look, feel and balance of a normal shoe while being able to achieve improved pivot action. The shoe sole (100) is particularly advantageous when incorporated into an athletic shoe or a work shoe for activities that require repeated pivotal movement.
