ABSTRACT:
A method of increasing the range of controlled movement of a door opened by a treadle operated door opening assembly is described, along with a treadle operated door opening assembly constructed in accordance with the teachings of the method. The method includes the step of mounting a contact member which projects from the first face of the door adjacent to the hinge edge and the bottom edge. With this modification when a person treads upon a radially extending pedal a shaft rotates causing a point of contact between the arm and the door to move sequentially from a first position substantially parallel to the first face of the door to a second position engaging the contact member substantially perpendicular to the first face of the door.
