Abstract
A foot treadle for use in opening a sliding door of the type mounted for initial movement in three directional dimensions from its closed position comprises a lever having an axis of rotation. The lever has a leg that depends generally downwardly from the axis and an arm that extends generally laterally from the axis. A pedal is mounted to the arm distally from the axis of rotation. The lever is mounted to a door jamb of a sliding door with the lever leg closely adjacent a lower end of the door for pivotal movement about the lever axis of rotation in pushing and sliding engagement with the door lower end. Upon a person stepping upon the pedal the lever leg applies a force laterally and upwardly against the door lower end thereby urging the door laterally and upwardly out of sealed engagement with the door jamb and floor as the door lower end slides outwardly from the door jamb in sliding contact with the lever leg.
