SHOE SOLE WITH ENERGY RESTORING DEVICE

摘要

The present disclosure describes a performance enhancing shoe sole that includes an anterior support structure and a posterior support structure that are connected by a first support structure. The anterior support structure and posterior support structure are flexible bent spring structures. The first support structure provides a plantar interface that includes a midfoot arch. The shoe sole is positionable in a shoe to provide shock absorption and controlled energy return from the posterior support structure to the first support structure. The shoe sole is an interconnected bent spring system that can be a single ribbon of flexible material defining multiple pivot angles or a multi-layered cantilevered flexible bent spring. The shoe sole can also include inserts that dampen shock.

主权项

1. A shoe sole that comprises:
a bent strip spring system, the bent strip spring system includes an elongate bent strip that has a first side, an opposed second side, a first edge and an opposed second edge; an anterior support structure of the bent strip spring system that includes a first anterior bent strip spring and a second anterior bent spring, the first anterior bent spring and second anterior bent spring biased to an initial position, the first anterior bent spring defines a first anterior flexible hinge and the second anterior bent spring defines a second anterior flexible hinge, a first anterior support beam connects the first anterior flexible hinge and the second anterior flexible hinge, a second support beam connects to the second anterior flexible hinge and extends in an anterior direction, the second support beam extends anterior to the first anterior flexible hinge, the second support beam extends from the second anterior flexible hinge defines an arcuate concave shape; a posterior support structure of the bent strip spring system that includes a first posterior bent strip spring and a second posterior bent strip spring, the first posterior bent spring and second posterior bent spring biased to an initial position, the first posterior bent spring defines a first posterior flexible hinge and the second posterior bent spring defines a second posterior flexible hinge, a first posterior support beam connects the first posterior flexible hinge and the second posterior flexible hinge, a second posterior support beam connects to the second posterior flexible hinge; and a first support structure that connects the anterior support structure and the posterior support structure.
