Abstract
A lock assembly that secures a door to an adjacent frame. The assembly includes an elongated base, a cam assembly mounted to the base including a housing, a lever, and a sliding member having a first end slidably connected to the lever and movable in a direction perpendicular to the base by rotation of the lever, an extension actuator having a proximal end movably connected to a second end of the sliding member, and a lock mechanism mounted to the elongated base and movable between unlocked and locked positions. The second end of the sliding member extends to a position within the housing upon full rotation of the lever. The extension actuator and base may permit modular addition of lock mechanisms at multiple locations.
Claims27
A locking assembly comprising:
- an elongated base for mounting to a door;
- a cam assembly mounted to said elongated base including a housing, a lever, and a sliding member having a first end movably connected to said lever and movable in a direction perpendicular to a longitudinal axis of said elongated base by rotation of said lever;
- an extension actuator having a proximal end movably connected to a second end of said sliding member;
- and
- a slide hook assembly mounted to said elongated base and movable between an unlocked position and a locked position and having a hook movable in a direction less than 180 degrees relative to the longitudinal axis of said elongated base, said slide hook assembly comprising a face plate, a member forming a slide channel and defining two opposing member slots parallel to the longitudinal axis of said elongated base, a hook body at least partially disposed within said slide channel and defining at least two hook body slots, and at least two pins, each of said at least two pins at least partially transversing one of said at least two hook body slots and each of said two opposing member slots;
- wherein said sliding member is movable by rotation of said lever to transfer said lock mechanism to said locked position;
- further wherein said second end of said sliding member extends to a position within said housing upon full rotation of said lever.
