Abstract
A lock for use as a multipoint lock, the lock having: a lock body, a lock tongue which is moveable between a locking position and a free position, an actuator to move the lock tongue, a deadlocking member in the lock body and which is moveable between a deadlocking position to deadlock the lock tongue and an undeadlocking position, and, attachment means attachable to a remote lock operator to move the operator without any lost motion.
Claims14
A lock which is adaptable for use as a single standalone lock or as a central lock in a multipoint lock assembly which has one or more remote locks each of which is connected to the central lock with a substantially rigid remote lock operator, the lock including:
- a lock body,
- a lock tongue that is movable between a locking position at which the lock tongue extends from the lock body and a free position at which the lock tongue is withdrawn at least partly into the lock body,
- an actuator the operation of which causes the lock tongue to move to the free position, and
- a deadlocking member in the lock body that is movable between a deadlocking position at which the deadlocking member deadlocks the lock tongue and an undeadlocking position at which the lock tongue is free to move relative to the deadlocking member, the deadlocking member having a portion that extends to adjacent a rear portion of the lock body and includes a rearwardly opening slot configured to receive with a press fit connection a forwardly extending projection on the remote lock operator for effecting longitudinal movement of the remote lock operator outside of the lock.
A multipoint lock assembly having one or more remote latches connected to a central lock by a substantially rigid remote lock operator that has a first formation, the central lock including
- a lock body,
- a lock tongue that is movable between a locking position at which the lock tongue extends from the lock body and a free position at which the lock tongue is withdrawn at least partly into the lock body,
- an actuator the operation of which causes the lock tongue to move to the free position, and
- a deadlocking member in the lock body that is movable between a deadlocking position at which the deadlocking member deadlocks the lock tongue and an undeadlocking position at which the lock tongue is free to move relative to the deadlocking member, the deadlocking member having a portion that extends to adjacent a rear portion of the lock body and which includes a rearwardly opening slot, and
- wherein the remote lock operator has a forwardly extending projection received in the rearwardly opening slot with a press fit connection so that the remote lock operator moves longitudinally outside the lock.
