Abstract
A multi-point locking arrangement is provided. The multi-point locking arrangement includes a primary lock bolt and an auxiliary lock bolt offset from the primary lock bolt. The multi-point locking arrangement, in an embodiment, uses a single actuation motion to transition between locked and unlocked states. The locking arrangement may also include a lockout device that prevents transitioning from the unlocked state to the locked state when the lockout device is not actuated. The locking arrangement may include a biased auxiliary strike plate that cooperate with the auxiliary lock bolt to provide improved alignment and a tighter seal.
Claims21
A multi-point locking arrangement comprising:
- a primary lock bolt;
- a first auxiliary lock bolt spaced from the primary lock bolt;
- a lock mechanism including a rotational input device operably coupled to the primary lock bolt and first auxiliary lock bolt to drive the primary lock bolt and first auxiliary lock bolt when rotated, the rotational input device rotatable between a locked state and an unlocked state, in the locked state, the primary lock bolt and first auxiliary lock bolt are extended and, in the unlocked state, the primary lock bolt and first auxiliary lock bolt are retracted;
- a lockout device transitionable between a released state and a lockout state, in the lockout state, the lockout device cooperates with the lock mechanism to prevent transitioning the rotational input device from the unlocked state to the locked state, in the released state, the lockout device permits the lock mechanism to transition the rotational input device from the unlocked state to the locked state, the lockout device configured to transition from the lockout state to the released state when the lockout device is depressed,
- a handle;
- a latch operably coupled to the handle, the latch being driveable from a latched state to an unlatched state by operation of the handle;
- and
- wherein operation of the handle to drive the latch from the latched state to the unlatched state is operable to depress the lockout device and drive the lockout device from the lockout state to the released state.
A multi-point locking arrangement comprising:
- a primary lock bolt;
- a first auxiliary lock bolt spaced from the primary lock bolt;
- a lock mechanism including a rotational input device operably coupled to the primary lock bolt and first auxiliary lock bolt, the rotational input device rotatable between a locked state and an unlocked state, in the locked state, the primary lock bolt and first auxiliary lock bolt are extended and, in the unlocked state, the primary lock bolt and first auxiliary lock bolt are retracted;
- and
- a biasing auxiliary strike plate including an opening through which the first auxiliary lock bolt extends when the lock mechanism is in the locked state, the biasing auxiliary strike plate including a biasing mechanism for biasing the first auxiliary lock bolt in a direction transverse to a plane in which the first auxiliary lock bolt transitions as it transitions between the retracted and extended states and through the opening, the biasing mechanism being a spring biased roller including a pin and a roller carried on the pin, a first spring acting on a first end of the pin and a second spring acting on a second end of the pin, the roller being positioned between the first and second ends of the pin and the pair of springs, the springs biasing the pin and roller in the direction transverse to the plane in which the first auxiliary lock bolt transitions between the retracted and extended states.
