Abstract:
An improved door knob/handle mechanism is described which opens, i. e. unlatches, the door through the mechanism of pushing, pulling or twisting the door knob/handle. When the door panel is to be opened in a direction so as to swing-away from the user, the door is opened either by pushing on the knob/handle, or twisting it. When the door panel is to open in a direction by swinging towards the user, the door is opened either by pulling the knob/handle or twisting it. The improved mechanism facilitates the opening of a door by those individuals who may be handicapped, suffer from arthritis, or have their hands filled while attempting to open the door, either inwardly, or outwardly.
