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.
Claims20
A locking assembly comprising:
- a) an elongated base for mounting to a door;
- b) 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;
- c) an extension actuator having a proximal end movably connected to a second end of said sliding member;
- and
- d) a lock mechanism mounted to said elongated base and movable between an unlocked position and a locked position, wherein said sliding member is movable by rotation of said lever to transfer said lock mechanism to said locked position;
- e) wherein said second end of said sliding member extends to a position within said housing upon full rotation of said lever.
A door locking assembly comprising:
- a) an elongated base for mounting to a door;
- b) a cam assembly mounted to said elongated base including a lever and a sliding member having a first end slidably connected to said lever and movable in a direction perpendicular to a longitudinal axis of said elongated base by rotation of said lever;
- c) an extension actuator having a proximal end movably connected to a second end of said sliding member;
- and
- d) a slide hook mechanism mounted to said elongated base and movable between an unlocked position and a locked position, wherein said extension arm is movable by rotation of said lever to transfer said slide hook mechanism to said locked position, said slide hook mechanism including:
- i. a face plate;
- ii. a member forming a slide channel and defining two opposing slots parallel to the longitudinal axis of said elongated base;
- iii. a hook body at least partially disposed within said slide channel and defining at least two hook body slots;
- and
- iv. 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 slots;
- e) wherein said face plate is constructed of essentially solid material to prohibit traversing bolts.
A door having a top, front and bottom edge, said door comprising:
- a) a cylinder lock interface mounted to said door;
- b) a door style mounted to said front edge;
- c) a cam assembly mounted to said door style including a housing, a lever rotatable at one end by rotation of said cylinder lock interface, and a sliding member having a first end secured to said lever and movable in a direction towards said front edge by rotation of said cylinder lock interface;
- d) an extension actuator having a proximal end movably connected to a second end of said sliding member;
- and
- e) a slide hook mechanism mounted to said door style at a location between said top edge and said cam assembly and having a hook body movably connected to a distal end of said extension actuator and movable from an unlocked position to a locked position extending beyond said front edge by rotation of said cylinder lock interface;
- f) wherein a second end of said sliding member remains within said housing upon full rotation of said lever.
