An adjustable latch configured to accommodate different backset lengths. The adjustable latch includes inner and outer housings, at least a portion of the inner housing being structured for axial and rotational displacement within the outer housing as an engagement projection of the inner housing is displaced about an adjustment slot of the outer housing. The apparatus may include a bolt assembly having a bolt rod and a latch bar, the bolt rod having projections that are structured to be adjacent to the latch bar when the bolt rod is at a first rotational position and at first or second axial positions. When the bolt rod is at a second rotational position, the axial positions of the bolt rod and the inner housing relative to at least the latch bar and outer housing, respectively, may be adjusted to adjust the backset setting of the latch.

An apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

An anti-burglar bar (1) for rolling shutters (2) or rolling gates, which are defined by a plurality of horizontal slats (3) associated with a winding roller and are slidable in a first and a second vertical guides (4,5) opposite to one another, comprises electromechanical control means (7) of a first and a second blocking elements (8) and (9), arranged slidingly in a body (11), which engage respectively in a first and a second retention blocks (10) associated with said first and second guides respectively, a first and a second feelers (12) being provided which engage respectively with a first and a second position sensors (13) for transmitting an electric signal, said electric signal activating said electromechanical control means (7) only when said first and second feelers (12) are simultaneously aligned with said first and second position sensors (13) respectively.

A latch hook length adjustment arrangement includes a latch hook body comprising a hook and a rod extending from the hook, an adjustment nut configured to threadingly couple to the rod, a plurality of detent pockets disposed in the first side surface of the adjustment nut, a bearing sleeve comprising one or more bearings, and a spring member configured to bias the adjustment nut against the bearing sleeve. The detent pockets and bearing(s) may retain the nut in a rotational position, thereby maintaining the positional length of the hook.
