Car door interlock

An interlock assembly comprising:

• a landing door interlock including a set of rollers are supported by a bracket assembly that is fixed at an associated landing door;
• elevator car door interlock including:
• a forward vane mounted for movement with an elevator car and extending in a vertical direction;
• a rearward vane spaced axially aft from the forward vane in a horizontal direction;
• a first linkage assembly coupling the forward vane and rearward vane together;
• a second linkage assembly coupling the forward vane and rearward vane together, wherein the second linkage assembly is axially spaced from the first linkage assembly in the vertical direction;
• a latch assembly having a door latch that is coupled to the first linkage assembly;
• a switch positioned forward of the forward vane in the horizontal direction and facing downward in the vertical direction;
• and
• a switch contact supported by the door latch to engage the switch in a locked position and disengage from the switch in an unlocked position;
• and
• wherein the forward vane and the rearward vane comprise a sensing mechanism that interacts with the set of rollers to detect when an elevator car is within a door landing zone.

A method comprising:

• providing a landing door interlock including a set of rollers are supported by a bracket assembly that is fixed at an associated landing door, wherein the set of rollers comprise a fixed interlock roller and an interlock unlocking roller that is spaced rearward from the fixed interlock roller in a horizontal direction;
• providing an elevator car door interlock mounted for movement with an elevator car, the elevator car door interlock including:
• a forward vane mounted for movement with an elevator car and extending in a vertical direction;
• a rearward vane spaced axially aft from the forward vane in the horizontal direction;
• at least a first linkage assembly coupling the forward vane and rearward vane together;
• a latch assembly having a door latch that is coupled to the first linkage assembly;
• a switch positioned forward of the forward vane in the horizontal direction and facing downward in the vertical direction;
• and
• a switch contact supported by the door latch to engage the switch in a locked position and disengage from the switch in an unlocked position;
• and
• wherein the method further includes at least one of:
• pivoting the door latch upwardly from underneath the switch to move the switch contact into engagement with the switch;
• detecting the elevator car in an associated door landing zone in response to interaction between the rearward vane and the interlock unlocking roller.
