Abstract
A door handle assembly that can be locked and unlocked using a key. The door handle assembly includes a bolt that is movable from an extended position to a retracted position. The first handle is coupled to the bolt and adapted to cause the bolt to retract when the first handle is pushed. A second handle is coupled to the bolt and adapted to cause the bolt to retract when the second handle is pulled. A key locking mechanism is coupled to the first handle. The key locking mechanism is adapted to selectively prevent the bolt from moving to the retracted position. A safety locking mechanism is coupled to the second handle. The safety locking mechanism is adapted to selectively prevent the bolt from moving to the retracted position.
Claims17
A door handle assembly comprising:
- (A) a first handle and a second handle;
- (B) a bolt movable from an extended position to a retracted position, the bolt having a retraction surface and a locking surface;
- (C) a first lever mechanism coupled between the first handle and the bolt, the first lever mechanism being adapted to engage the retraction surface;
- (D) a second lever mechanism coupled between the second handle and the bolt, the second lever mechanism being adapted engage the retraction surface;
- (E) a key locking mechanism coupled to the first handle, the key locking mechanism being adapted to selectively engage and disengage the locking surface;
- (F) a safety locking mechanism coupled to the second handle, the safety locking mechanism being adapted to selectively engage and disengage the locking surface;
- and
- (G) wherein the first lever mechanism comprises:
- a first lever connected to the first handle, a second lever engagable with the retraction surface and a gear assembly connected between the first and second levers.
A door handle assembly comprising:
- (A) a bolt movable from an extended position to a retracted position;
- (B) a first handle coupled to the bolt and adapted to cause the bolt to retract when the first handle is pushed;
- (C) a second handle coupled to the bolt and adapted to cause the bolt to retract when the second handle is pulled;
- (D) a key locking mechanism coupled to the first handle, the key locking mechanism being adapted to selectively prevent the bolt from moving to the retracted position;
- (E) a safety locking mechanism coupled to the second handle, the safety locking mechanism being adapted to selectively prevent the bolt from moving to the retracted position;
- and
- (F) wherein a push lever mechanism connects the first handle and the bolt and wherein the push lever mechanism comprises:
- a first lever connected to the first handle;
- a gear assembly connected to the first lever;
- and a second lever connected to the gear assembly and adapted to engage the bolt.
A door handle assembly comprising:
- (A) a bolt movable from an extended position to a retracted position;
- (B) a first handle coupled to the bolt and adapted to cause the bolt to retract when the first handle is moved;
- (C) a second handle coupled to the bolt and adapted to cause the bolt to retract when the second handle is moved;
- (D) means for allowing the first or the second handle to selectively retract the bolt;
- (E) a first locking mechanism mounted to the first handle, the first locking mechanism being adapted to keep the bolt in the extended position, the first locking mechanism including a locking slide, the locking slide being adapted to engage the bolt as the first locking mechanism is actuated;
- and
- (F) wherein a lock pin engages the locking slide when the locking slide is engaged with the bolt.
