Abstract:
A foot operable door opener operates, without using one's hands, and without an electrical assist. The entrance cycle is initiated by stepping on a pedal. This force drives the pedal a ¼ turn, engaging a soft wheel to open the door. The pedal is hard linked to a crank arm which goes into a unidirectional crank shaft hub to turn the wheel. The downward pressure from the pedal pivots a ratcheted hinge connected to a bracketed spring-loaded wheel assembly to keep constant pressure to the ground. A gear box or multiple pumps of the pedal turns the wheel two or more 360 degrees rotations, opening the door to allow the entrant to pass until the foot pedal is dis-engaged. This action releases the ratcheting hinge mechanism, allowing the spring assisted wheel assemble to rotate to its original up position, releasing the wheel from the ground, allowing the door to close.
