The present disclosure relates to locks, and particularly to locks for doors. More particularly, the present disclosure relates to a removable lock for use with roll-up storage doors.
SUMMARY
According to the present disclosure, a storage facility includes a number of storage compartments and doors for controlling access to the storage compartments. The doors move along guide tracks between a lowered-closed position and a raised-opened position relative to respective entryways into the storage compartments. Latches are coupled to the doors for blocking movement of the doors at the selection of a user. One or more locks can be used with the doors to block access to the storage compartments.
In illustrative embodiments, a locking wedge engages with the guide track and the door to block movement of the door at the selection of an authorized user. The locking wedge includes a frame, a head, and a lock. The head is coupled to the frame and extends through a slot in the guide track to block movement of the locking wedge along the guide track. The frame engages with corrugations of the door to block movement of the door relative to the guide track. The lock blocks removal of the locking wedge from the guide track at the selection of a user.
In illustrative embodiments, the lock includes a lock cylinder coupled to the frame and a cam coupled to the lock cylinder. The cam is movable between an unlocked position aligned with the frame and a locked position extending outward from the frame. The locking wedge can be mounted and dismounted relative to the guide track when the cam is in the unlocked position, and removal of the locking wedge from the guide track is blocked when the cam is in the locked position.
In illustrative embodiments, an authorized key allows a user to operate the lock cylinder and rotate the cam for mounting or dismounting the locking wedge relative to the door and the guide track.
In illustrative embodiments, the lock includes catch pins coupled to the head and a pin mover coupled to the catch pins. The catch pins extend outward from the head in an extended position to engage with the guide track and block removal of the locking wedge. The pin mover engages with the catch pins to move the catch pins toward one another to a retracted position to allow removal of the locking wedge from the guide track at the selection of a user.
In illustrative embodiments, the lock is an electronic lock and includes the catch pins, the pin mover, a motor, a battery, and a control board. The control board controls the delivery of power from the battery to the motor for controlling operation of the motor. The pin mover is coupled to the motor. Activation of the motor by an authorized user causes rotation of the pin mover to move the catch pins to the retracted position.
