Abstract
In at least one embodiment, a door handle assembly is provided. The door handle assembly includes a door handle and a mount. The door handle can be attached to the mount. The door handle is adapted to allow a bolt to move into and out of a wall aperture. A cam assembly is disposed adjacent the bolt. The cam assembly includes a locking cam. The locking cam is adapted to abut at least a portion of the bolt. The locking cam is moveable between a locked and an unlocked position. A lock release mechanism is coupled to the cam assembly and to the door handle. The lock release mechanism is adapted to disengage the locking cam from the bolt when the door handle is actuated such that the bolt is free to move.
Claims19
A door handle assembly comprising:
- (A) a door handle having an actuator extending from the door handle;
- (B) a mount, the door handle being attached to the mount;
- (C) a bolt, the bolt being movable from a first bolt position where at least a portion of the bolt is inside a wall aperture thereby engaging the door into the wall aperture to a second bolt position where the portion of the bolt is outside the wall aperture thereby disengaging the door from the wall aperture, the bolt having an actuator opening formed therein, the actuator passing into the actuator opening, wherein when the door handle is moved, the bolt moves from the first bolt position to the second bolt position;
- (D) a cam assembly disposed adjacent to the bolt, the cam assembly comprising:
- (a) a locking cam configured to abut at least a portion of the bolt and to lock the bolt in the first bolt position;
- and
- (b) a cam latch attached to one end of a cam shaft, the cam latch being adapted to allow a user to actuate the cam assembly;
- wherein the cam assembly is moveable between an unlocked position and a locked position, the locked position corresponding to the bolt being located in the first bolt position;
- and
- (E) a lock release mechanism coupled with the cam assembly and configured to cause the locking cam to move from the locked position to the unlocked position, the lock release mechanism comprising:
- (a) a release cam abutting the locking cam;
- and
- (b) a return spring connected to the release cam, the return spring being adapted to move the release cam and the cam assembly to the unlocked position when the door handle is moved.
A door handle assembly comprising:
- (A) a door handle;
- (B) a mount, the door handle being attached to the mount;
- (C) a bolt, the door handle being adapted to allow the bolt to move into and out of a wall aperture;
- (D) a cam assembly disposed adjacent the bolt, the cam assembly comprising:
- (a) a locking cam configured to abut at least a portion of the bolt and to lock the bolt in a locked position;
- and
- (b) a cam latch attached to one end of a cam shaft, the cam latch being adapted to allow a user to actuate the cam assembly;
- wherein the locking cam is moveable between the locked position and an unlocked position;
- and
- (E) a lock release mechanism coupled to the cam assembly and to the door handle and configured to disengage the locking cam from the bolt when the door handle is actuated such that the bolt is free to move, the lock release mechanism comprising:
- (a) a release cam coupled with the locking cam and the door handle;
- and
- (b) a return spring connected between the release cam and the mount, the return spring being adapted to urge the locking cam toward the unlocked position.
A door assembly comprising:
- (A) door handle means for opening and closing a door;
- (B) bolt means for selectively engaging a door frame, the bolt means being movable from a locked first bolt position where the bolt means engages a door frame aperture to an unlocked second bolt position where the bolt means is retracted from the door frame aperture, the door handle means being adapted to selectively engage the bolt means;
- (C) cam means for locking the bolt means in the locked first bolt position;
- and
- (D) lock release means for releasing the cam means from the locked first bolt position to the unlocked second bolt position, thereby unlocking the bolt means.
