Abstract:
A sensor for an interconnected lock assembly which can sense whether the door is in an opened or closed state. The interconnected lock assembly comprises a first lock assembly operably connected to a deadlatch assembly. A second lock assembly operably interconnected with the first lock assembly by a rack mounted on a carrier component. The second lock assembly is operably connected to a deadbolt latch assembly. The deadbolt latch assembly comprises a deadbolt movable between an extended position when the carrier component is in a lowered position and a retracted position when the carrier component is in a raised position. The lock assembly further includes a sensor component positioned within said deadlatch assembly in a predetermined manner to detect when said door is an open or closed position. The information is relayed to an electronic control module.
Abstract:
A panic door lock includes a housing and a dead bolt that is movable in the housing between an extended position and a retracted position. The dead bolt is spring-loaded and tends to be moved to the extended position. The dead bolt has a slot defined in place therein. A detent has an inner claw adapted to enter the slot and retain the dead bolt in the retracted position as long as the dead bolt is moved to the first retracted position. In addition, a spring-loaded trigger having a tip normally extended out the housing is provided. The trigger is engagable with the detent so that the inner claw may exit the slot and release the dead bolt from the retracted position when the tip of the trigger is pressed into the housing.
Abstract:
A latch-and-bolt lock with simultaneous actuation of the bolt and of the latch during closure, the latch and the bolt being actuated by an elastic element so as to protrude from the lock in order to engage in respective selvages of the jamb, the lock including; a sensor for detecting a closed position of a door wheron the lock is fitted, the sensor being movable at right anles to a faceplate of the lock between an external position and an internal position relative to the lock and being retained in the internal position by abutment against the doorjamb; a slider which is guided parallel to the latch; a plate for blocking the bolt, which is guided transversely to the slider; a lever which is articulated to the slider and has a first arm which is operatively associated with the sensor and a second arm which is adapted to assume a position for blocking the latch when the sensor and the latch are inside the lock, a member for the actuation of the plate being arranged on the slider and being such that when the latch, after abutment against the doorjamb, is aligned with the corresponding selvage of the doorjamb, by way of the stroke of the latch for engagement in the selvage, the slider is moved into a position in which the actuation member disengages the plate from the bolt and engages the bolt in the corresponding selvage under the thrust of the elastic element.
Abstract:
An espagnolette-lock for use on a leaf within a sash-frame having a casing, an operating rod movable between a locked position and an unlocked position, a controller for actuating the operating rod, a springy element for automatically restoring the operating rod to the locked position, a manual controller for moving the operating rod to the unlocked position and for restoring the springy element to a compressed condition, a locking mechanism for maintaining the operating rod in the unlocked position during an opening of the leaf from the sash-frame, and an unlocking mechanism for releasing the locking mechanism when the leaf is closed into the sash-frame so as to return the operating rod to the locked position. The locking mechanism includes a toggle joint having a first rod and a second rod connected together by a fulcrum. The first rod is connected through a hinged joint to the operating rod. The second rod is connected through a hinged joint to the casing. The fulcrum and the respective hinged joints are substantially in alignment parallel to the operating rod when the operating rod is in the unlocked position.
Abstract:
A multipoint mortise lock assembly includes an extended face piece mounted flush along the edge of a door, a mortise lock connected to the face piece, and a pair of hook bolt latch mechanisms mounted to the face piece above and below the mortise lock. An elongated actuator, which is preferably a flat rod slidingly mounted to the back of the face piece, acts to extend and retract the hook bolts in synchronism with a deadbolt in the mortise lock. The actuator is connected between a deadbolt arm in the mortise lock, which drives the deadbolt, and the hook bolt latch mechanisms. The deadbolt arm is driven conventionally, such as by a key or a thumb latch, and the design allows one hand operation of the multipoint mortise lock assembly.
Abstract:
A lock for a door including a latch bolt and a further bolt mounted in a housing for parallel displacement relative to the housing. A bearing is fixed in place in the housing and along with a turning element and a two-armed hinged lever, also mounted to the housing operate on the latch bolt and the further bolt. The two arms of the two-armed hinged lever are pivotably connected with each other at their free ends with one of the arms receiving the fixed bearing between its ends, and with one of the arms being connected to the turning element and the other of its arms being connected to the further bolt.
Abstract:
A door lock has four separate locking bolts operated or controlled by a single key-operated tumbler lock. The key-operated lock is located directly above two conventional external doorknobs, in a conventional arrangement, so that a would-be thief is unaware of the fact that the door lock contains four locking bolts, rather than the two locking bolts that are conventionally used. The four locking bolts achieve a level of security that is not attainable with the conventional two locking bolt arrangement.
Abstract:
The invention is a mortise lock constructed for very simple conversion between multiple functions and left and right hand openings. The lock can include or omit retraction of the latch bolt from either side with a key, permanent locking of either side's retractor, removal of the stopworks, simultaneous retraction of the latchbolt and deadbolt, or locking the retractor when the deadbolt is thrown. All of these conversions are accomplished without opening the case cover by the insertion or removal of screws or parts through holes in the cover or case, with the screws either stopping a part from moving or providing a catch upon which a part acts. The changeover between right and left handed openings is accomplished through the backplate with removal of only the armor plate, by removing, reversing, and reinstalling the latchbolt.
Abstract:
An interconnected lock assembly for use on a door includes a first latch adapted to be positioned in a first bore in the door and a second latch adapted to be positioned in a second bore in the door, spaced from the first bore. There is an outside operating member operably connected to the first latch for causing operation thereof and there is an inside operating member operably connected to the first latch for also causing operation thereof. There is an interconnecting mechanism operably connected to the inside operating member and to the second latch. The interconnecting mechanism is effective to cause operation of the second latch when the first latch is operated by the inside operating member. The interconnecting mechanism is adjustable as to length to accommodate variant spacing between the first and second bores.
Abstract:
A lock having a lock cylinder 22, a pusher nut 8, a catch 5 and a safety bolt 4, which can be actuated by the lock cylinder 22. The catch 5 is also retractable by means of the pusher nut. A catch locking slide 35 is displaceable from a release position to a locked position by pressure on the catch. A lever system 39, 40, 41 connects the locking slide 35 with the safety bolt 4 and has a dogging portion which embraces the locking slide 35. The dogging portion is actuated into a dogging position solely by pushing in and moving out of the catch 5, without operating the lock cylinder or a pusher spindle.
