A smart window/door opening-closing device that can easily be installed for use with an existing door or window or can be built-in by the door or window manufacturer, can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet, (c) automatically by a voice command and/or (d) automatic in response to external sensors, is easily disengaged when use is not desired, provides safety and security to prevent unwanted opening or closing of the door or window, and is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.

An electromechanical lock which is configured to provide a mechanical latch holdback feature, whereby a key is useable to retract a latch of the lock, the key can be removed, and the latch remains mechanically held back. The held back latch is remotely releasable. As such, a correctional officer can use his key to mechanically hold back the latch, such that the lock remains open. Subsequently, a control signal can be sent from a remote location causing the latch to be released and extended, such that the lock locks. This ability to remotely override the mechanical latch holdback is useful in a correctional facilityfor example, when the mechanical latch holdback has been engaged for cell doors and an emergency situation arises where a quick remote lockdown may be necessary, instead of having to perform the time-consuming task of re-locking the doors one-by-one, locally by key.

A latch assembly for a door includes automatically deployable deadbolt. When the door is closed and the latch engages a strike plate, the deadbolt automatically extends into a corresponding opening in a door jamb to secure the door.

The present application provides a door lock, comprising: a door lock, comprising: a latch head for locking a door of the top loading electrical appliance, the latch head being rotatable about an axis; and a limiting mechanism for limiting rotation of the latch head before the door of the top loading electrical appliance reaches a closed position. The latch head has a latch head unlock position and a latch head lock position, the latch head rotating between the latch head unlock position and the latch head lock position; and the limiting mechanism is arranged for limiting the latch head from rotating from the latch head unlock position to the latch lead lock position before the door of the top loading electrical appliance reaches a closed position. The door lock of the present application can lock the door of a washing machine safely and accurately.

A multi-point sliding door latch intended to fit within standard sized opening in the stile of a sliding door. Preferably the latch has at least two hooks oriented in opposite directions that slide in a generally linear manner between an unlatched and latched position in response to rotation of a pair of actuators located within the latch housing. Preferably, the latch includes reinforcement blocks defining cavities with a portion of the hooks extending into the cavities when the hooks are in the latched position.

A multipoint lock for securing a door panel is described. The multipoint lock includes a first latch, a second latch, a first hub rotatable with at least one of a thumb-turn knob or a key, and a second hub rotatable with a handle lever. Upward rotation of the handle lever causes both rotation of the first hub and rotation of the second hub in the same rotational direction

Examples described herein relate to a latch for releasably coupling objects. In some such examples, the latch includes a receiver, a torque member, and a handle. The receiver includes a lobe to releasably engage an anchor point within a recess of the receiver. The torque member is rotatably coupled to the receiver to rotate the receiver. The handle includes a torque portion rotatably coupled to the torque member to rotate the torque member and includes a lever extending from the torque portion.

Fenestration systems and associated methods include use of a lock assembly having a housing, a cam gear, a reversal gear, and one or more catches. Various aspects relate to enhanced locking/security, including repeatability and overall efficacy.

A latch includes a protrusion that extends from a latch body. The protrusion moves from a fully extended position to a partially extended position when the door or window to which the latch is mounted is moved to a closed position. This movement of the protrusion disengages an anti-slam mechanism, allowing movement of a latch mechanism. Further, the partially extended protrusion engages in an anti-lift recess in the strike. Alternatively, the protrusion may extend from the strike and engage with an anti-lift recess in the latch body.

Embodiments of the invention are directed to merchandise security devices, systems, and methods for protecting an item of merchandise from theft. For example, a merchandise security device may include a lock configured to be secured to a movable structure and a strike plate configured to be secured to a fixed support structure. The movable structure is configured to move along a path into engagement with the fixed support structure to secure the item of merchandise therein in a locked state and to move out of engagement with the fixed support structure for removal of the item of merchandise in an unlocked state. The lock is configured to engage the strike plate in the locked state and to disengage the strike plate in the unlocked state, and the lock is configured to engage the strike plate along the same path as the movable structure.
