A latch arrangement for fastening a panel of a door or a window to a frame element is provided. The latch arrangement includes a locking element mounted on the frame element and displaceable between a locked position in which the locking element can be engaged with a depression formed on the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element can be disengaged from the depression on the panel unlocking thereby the panel from the frame element; an actuating mechanism including a manually operable handle, the actuating mechanism being mounted on the panel and being configured to selectively engage the locking element and to displace the locking element away from the depression to the unlocked position.

The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.

A safe locking system that provides a means to operate one of two (or more) safe locks of any type to facilitate safe opening of a door. The safe door can be opened by operating either of two locks, regardless of the type or style; e.g., e-locks and mechanical locks. A sliding bar assembly is mounted to the rear face of the safe door for displacing the boltwork into and out of the door frame. Extension of the lock bolts of both locks prevents movement of a main locking bar and attached boltwork, which prevents a user from opening the door. Retraction of either of the lock bolts permits sliding movement of the main locking bar, such that a user can unlock the door from the frame.

A deadbolt system securing an access point includes a deadbolt and a deadbolt sensor configured to characterize the performance of the deadbolt. The deadbolt system generates a resistance signature when the deadbolt is moved between a retracted and extended position which is comparable to a threshold or a previously recorded resistance signature. The comparison may determine the presence of one or more performance inhibitors which may be conveyed to an operator through a local or remote indicator.

An electronic lock with an electronic sensing arrangement to accurately sense relative positions of a bolt which mechanically locks a door, such as a door of an electronic drop safe, and to also sense an electronically controlled plunger which locks the bolt in place. The arrangement provides a mechanism for sensing a variety of mechanical malfunctions, as well as, potential fraud or tampering situations.

A coin operated lock assembly (30) is provided for attachment to a locker (12), the locker including a cabinet (14) and a door (16). The cabinet defines a locker loop (18) for locking the door using a padlock or the like. The coin operated lock assembly (30) includes a coin operated key lock mechanism including a locking plate (50) which is moved by operation of the key lock, wherein insertion of a coin in the lock allows the door to be locked and the key removed from the lock and wherein the locker is locked by means of a bolt (42) which is fixed to, or movable by, the locking plate (50) and which passes through the locker loop (18) of the locker when the assembly is attached to the locker door.

A door lock may include a latch bolt head and a blocking pin. The latch bolt head may be configured to move between an extended position and a retracted position to selectively engage a latch head pocket of a door jamb. The latch bolt head may also be configured to move between a first rotational position and a second rotational position, wherein the blocking pin is configured to prevent movement of the latch bolt head from the first rotational position to the second rotational position when the blocking pin is in an engaged position.

A sash latch for engagement with a side jamb of a window includes an upper member with a spring cavity and a stop wall, a forward slot for engagement with an upper surface of a sash and a latch extension. The latch extension includes a substantially planar surface and an inclined planar surface extending at an acute angle relative to the substantially planar surface. The inclined planar surface includes a notch at a proximal end thereof, wherein the notch receives an edge of a wall of the side jamb when a heavy wind load is applied to an outer facing surface of the sash to restrain the sash relative to the side jamb.

A latch arrangement for fastening a panel of a door or a window to a frame element is provided. The latch arrangement includes a locking element mounted on the frame element and displaceable between a locked position in which the locking element can be engaged with a depression formed on the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element can be disengaged from the depression on the panel unlocking thereby the panel from the frame element; an actuating mechanism including a manually operable handle, the actuating mechanism being mounted on the panel and being configured to selectively engage the locking element and to displace the locking element away from the depression to the unlocked position.

A latch arrangement for fastening a panel of a door or a window to a frame element, the panel including a depression is provided. The latch arrangement includes a locking element pivotally mounted on the frame element and displaceable between a locked position in which the locking element is engaged with the depression of the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element is disengaged from the depression of the panel unlocking thereby the panel from the frame element, a stop latch selectively deployable to secure the locking element in the locked position, precluding thereby displacement of the locking element to the unlocked position; and an actuating mechanism configured to selectively pivot the locking element away from the depression to the unlocked position.
