A latch arrangement for a sliding wing has a latching member that is movable by magnetic force from first position in which it is at least partially retracted within a latch housing, to a second position in which it extends at least partially out of the housing, to be received in a strike. The strike comprises a magnet or ferromagnetic arrangement to attract the latching member into a receiving and engaging formation of the strike when the sliding wing is located at or adjacent the strike.

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

Certain aspects of the technology disclosed herein include an apparatus and method for a extending a deadbolt. The electromechanical lock can include a deadbolt extending device disposed between a main housing and a deadbolt. The deadbolt extension device can be used to adapt the electromechanical lock to doors of various sizes. The deadbolt extension device can include another electrical connection and another attachment mechanism for the deadbolt. The another electrical connection can be configured to electrically connect the deadbolt with the main housing. The another attachment mechanism can be configured to attach the deadbolt a pre-defined distance apart from the main housing.

Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.

Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

Disclosed embodiments include a mounting apparatus for a sliding security barrier that includes unique security features that ensure the sliding security barrier is secure and does not suffer problems that exist with conventional security doors and windows. The sliding security barrier is configured to be implemented using tracks that are common to conventional sliding patio screen door or windows. Additional security features include a unique striker plate, a lift protector at a corner, adjustable top and/or bottom channel caps, an interlock, and a uniquely shaped lock. These features provide greater security at a lower cost because they use an existing sliding door or window sash and channels but provide a secure attachment that inhibits tampering and removal of the sliding screen barrier.

Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.

A guard locking element (4) actuatable by means of an electric drive (6). By means of the electric drive (6), the guard locking element (4) can be brought into a blocking position such that an actuator (2) of a safety switch is locked by said guard locking element. The guard locking element (4) is connected to the electric drive (6) by means of a coupling (11) such that a rotary motion of the electric drive (6) is converted into a purely translatory motion of the guard locking element (4).

A sliding door latch system and method is disclosed herein. The sliding door latch system is used to prevent movement of a sliding door between a closed position and an open position relative to a fixed door frame. The device may be installed as a secondary safety latch on a sliding door having a primary latch that is located at an elevation within the reach of the child. The device may be installed at an elevation above the reach of the child, but readily within the reach of an adult user. The sliding door latch includes a latch arm located outside the sliding door to simplify installation. The latch arm is user-locatable in a latched position, a momentarily released position, and a held-in-release position.

Determining a position of a deadbolt used to lock and unlock a door is disclosed. An electromechanical lock can include a deadbolt that can retract or extend along a linear path as the door is to be locked and unlocked. A sensor such as an accelerometer can rotate along a non-linear path as the deadbolt moves along a linear path. The accelerometer can determine a gravity vector that can be indicative of a position of the accelerometer along the non-linear path. A controller can then determine a position of the deadbolt based on the gravity vector.
