A fenestration assembly includes a frame assembly, a movable sash assembly and a lock assembly. The lock assembly includes a first lock and a second side lock. The first lock operatively locks and unlocks the moveable sash to the frame assembly in a first direction only when the movable sash is in a fully closed position. The first side lock operatively locks and unlocks the movable sash in a second direction perpendicular to the first direction both when the movable sash is in the fully closed position and a partially open position.

An electronic locking device to secure linear transitioning or sliding doors. The electronic lock may include a bolt driven by a motor between a locked or extended position and an unlocked or retracted position. The bolt may be coupled to a sled, the sled moved by the motor between a forward position, placing the bolt in the locked position, and a rearward position, placing the bolt in the unlocked position. The motor may drive a drive screw to move the sled.

A locking device for a window or a door, wherein the window or the door has a sash slidable in a horizontal direction within a frame. When a user turns on a switch to control a block to move from the first position to the second position, the block protrudes out of a vertical surface of the sash, thereby driving a linkage member to disengage from the frame. At this time, the user could hold and push the block in the horizontal direction to move the sash between a third position and a fourth position. When the sash is pushed back to the third position, the block could be controlled to move back to the first position, namely back to a mounting groove, thereby moving the linkage member to a position where the linkage member is engaged with the frame. A method of operating thereof is provided as well.

A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.

A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

A fenestration hardware assembly includes a blade socket including a blade recess and an operator interface feature rotatably coupled with an operator housing. A latch blade is movably coupled with the operator housing. The latch blade is movable between deployed and withdrawn positions. In the deployed position at least a portion of the latch blade is received in the blade recess of the blade socket. In the withdrawn position the portion of the latch blade is recessed from the blade recess. The operator interface feature is rotatable between at least locked and unlocked configurations. In the locked configuration the latch blade is in the deployed position and received in the blade recess. In the unlocked configuration the latch blade is translated from the deployed position to the withdrawn position and withdrawn from the blade recess according to rotation of the operator interface feature.

Tamper proof wall mounted strike assembly for barn door is a strike or strike assembly that attaches to a wall or a door molding and functions with a lockset installed on a barn door. Tamper proof wall mounted strike assembly functions to receive the latch or deadbolt from the door lockset on the barn door wherein the latch or deadbolt can be latched or locked within the strike assembly to latch and/or lock the barn door and the latch or the deadbolt can be unlatched or unlocked within the strike assembly to unlatch and/or unlock the barn door. Tamper proof wall mounted strike assembly includes a strike housing assembly that mates with a wall plate assembly by interlocking teeth on each assembly to yield a tamper proof connection there between that is without any exposed screws or fasteners when the barn door is in the closed position to yield a tamper proof wall mounted strike assembly.

Fenestration lock assemblies, fenestration units including the lock assemblies, and methods of assembling the lock assemblies. The lock assemblies use a cam and follower design that transfers rotary motion to a lock bolt that moves in translation between an extended/locked state and a retracted/unlocked state.

A locking apparatus for a sliding closure slidable within a frame is disclosed. The locking apparatus comprises at least one locking tang movable transversely to the closure plane, between a locking position and a release position wherein, when in the locking position the locking tang extends laterally, in a direction transverse to the closure lane, beyond the closure to be received within a corresponding locking recess in the frame, such that the locking tangs resist opening of the closure, and when in the release position the locking tang is withdrawn within the dimensions of the frame, such that the closure may be opened or closed. The locking mechanism may also comprise a sensor configured to detect when at least one of the locking tangs are in the locked or released position, and, optionally to trigger an alarm if the locking tang is disengaged.
