ABSTRACT:
A pedal is secured to the bottom of a door and a clamp is secured to the door knob. The pedal is coupled to the clamp through a cord or the like. Operation of the pedal by a user turns the knob through the clamp, whereby the door latch is disengaged from a latch plate in the door jamb to free the door therefrom, so that the door may be opened by the user by pushing with a hand or foot, as the case may be.
