Sliding pin lock mechanism for overhead door with microswitch
A door lock mechanism for an overhead door employs a sliding pin or rod that passes into the path of the rollers in the track, and obstructs the roller from movement in the direction to open the door. A spring in the door lock frame biases the sliding pin towards a proximal open position. The sliding pin has a swing arm that extends radially from the pin's proximal end, and which engages retaining structure at the proximal end of the door lock frame. In the lock position the distal end of the sliding pin blocks movement of wheels or rollers in the vertical track. The arm is rotated out of engagement with the retaining structure to release the pin so it may slide proximally to an unlocked position. A microswitch in the interior of the lock switches on when the sliding pin is moved to the locked position and turns off when the pin is returned to its unlocked position. A sleeve disposed over the proximal part of the spring engages the actuator of the microswitch.
