Abstract
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 an arm that extends radially from its proximal end, and which engages retaining structure at the proximal end of the door lock frame. The arm is rotated out of engagement with the retaining structure to release the pin so it may slide proximally to an unlocked position. The pin may slide into a receiver housing mounted on a door panel.
Claims9
A locking mechanism that attaches to the vertical track of an overhead door to hold the door locked in its lowered or closed position, the mechanism comprising:
- a frame, including a distal mounting portion that is adapted to be affixed onto said vertical track, the frame extending proximally therefrom;
- a sliding pin that passes through an opening in the distal mounting portion of the frame, with an arm extending radially from a proximal end of said sliding pin;
- a spring contained within said frame and urging said sliding pin in a proximal direction;
- and
- retaining structure at a proximal end of said frame for engaging said radial arm when the sliding pin is slid distally to a locked position, and the radial arm being capable of being rotated out of engagement therewith to permit the pin to slide proximally to an unlocked position.
