Lock handle assembly
A lift-to-lock handle assembly 1 comprising a first shaft 7 rotating about a first axis and carrying a handle 9, a second shaft 19 rotating about a second axis parallel to, but spaced apart from, the first axis. An electric motor 41 rotates the second shaft 19, and a shaft sensor system 29 detects rotation of the first shaft 7. An electronic control unit receives a signal from the sensor 29 and causes rotation of the electric motor 41 in a direction determined by the direction of rotation of the first shaft 7. By lifting the handle, the second shaft is rotated by the motor which places the lock in a locked position. The sensor may include one or two light beam sensors (33 35 Fig 2) and beam breaker in the form of a flag (37 Fig 2). The sensors may be set either side of the flag to detect rotation in either direction. The light beams may be activated by a magnet and reed switch combination (39 Fig 2) to conserve battery life.
