A lock assembly comprises a driving member, a drive assembly, and an engaging member. The drive assembly comprises a drive connector operatively connected to the driving member, a lead screw operatively connected to the drive connector, a carriage configured and arranged to move along the lead screw, and an elongate member operatively connected to the carriage. The driving member is configured and arranged to rotate the drive connector, and the drive connector is configured and arranged to rotate the lead screw. Rotation of the lead screw moves the carriage along the lead screw and the elongate member moves with the carriage between locked and unlocked positions. The engaging member is configured and arranged to selectively engage the elongate member in the locked position.

A door locking apparatus is provided including a first plate, a second plate, a front assembly, a lock clip, and at least one control. The first plate includes at least one vertical slot. The lock clip is rotatably attached to the front assembly and includes at least one horizontal slot in a first end. The at least one control is mounted to the first plate and includes at least one protrusion. The at least one protrusion projects through the at least on vertical slot and through the at least one horizontal slot. The at least one control moves vertically between a first position and a second position. The lock clip is in an open position when the at least one control is in the first position and a locked position when the at least one control is in the second position.

A locking assembly for a casement window including a frame having an elongated surface, comprising a tie bar guide adapted to be mounted on the window frame surface, the tie bar guide having first and second receiving grooves for slideably receiving segments of a tie bar in a tongue and groove manner, and a tie bar adapted to slide axially in a direction parallel to the window frame surface and having a partially curved profile and a cross-section comprising a flat central portion with a first segment comprising a first tongue and a second segment comprising a second tongue, the first and second segments on opposite sides relative to the central portion. The tie bar is slideably received in the tie bar guide such that the tie bar first tongue is received in the tie bar guide first receiving groove and the tie bar second tongue is received in the tie bar guide second receiving groove, to permit the position of the tie bar to be adjusted with respect to the tie bar guide in the longitudinal direction while preventing movement of the tie bar in a direction perpendicular to the longitudinal direction. One of the tie bar and tie bar guide has an opening in an exterior surface thereof and the other has a projection extending in a direction of the opening, wherein when the tie bar is slideably received within the tie bar guide, the projection and opening act as a detent to maintain the tie bar guide in a desired position.

A low profile actuating window lock for casement windows having a longitudinal slot in a sidewall of the casing for the lock, wherein an actuator including a fork component translates within the slot in a direction opposite movement of the handle, the handle pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle and restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

A sash window fastener includes a lock assembly, latch assembly, and stop member. The lock assembly mounts upon the meeting rail, and includes a pivotable cam to engage a keeper on the master frame, and a pivotable arm that acts as a follower. The arm interconnects with the latch within the meeting rail, so cam rotation controls arm positioningcausing translational movement of the latch. The cam can occupy four positions causing four corresponding latch positions: an extended position securing the cam to the keeper, with the latch engaging the master frame to prevent tilting, and contacts a first stop to redundantly lock the window; a first retracted position permitting sliding of the window, but limited by the slightly retracted latch clearing the first stop but contacting a second stop; a second retracted position permitting sliding beyond the second stop, but preventing tilting; and a third retracted position permitting tilting.

A pet cage door system including a door frame multiple insertion buckles protruding toward a side of door frame. The door frame has a door that rotates relative to the door frame, and the door has a door bolt that transversely slides relative to the door. A first end of the door bolt is inserted into one of the insertion buckles, and a second end of the door bolt is connected to a vertical bar that transversely moves relative to the door. An end portion of the vertical bar has a transverse bar. The transverse bar has a turning-back bar that extends from an end of the transverse bar that and curves to form a semi-circular portion. The turning-back bar then extends parallel to the transverse bar, is spaced from the transverse bar, and is adapted to engage a second one of the insertion buckles.

The pivot points of the handle and restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

A door locking apparatus is provided including a first plate, a second plate, a front assembly, a lock clip, and at least one control. The first plate includes at least one vertical slot. The lock clip is rotatably attached to the front assembly and includes at least one horizontal slot in a first end. The at least one control is mounted to the first plate and includes at least one protrusion. The at least one protrusion projects through the at least on vertical slot and through the at least one horizontal slot. The at least one control moves vertically between a first position and a second position. The lock clip is in an open position when the at least one control is in the first position and a locked position when the at least one control is in the second position.

The present disclosure relates to a lock for a double pane door. A lock body includes a cylinder and a bolt. A main body has front and rear faces, a bore receiving the cylinder of the lock body mounted on the rear face so that a key can be inserted in the cylinder from a front of the main body, and a pair of extensions projecting from the rear face of the main body. A bracket is mountable to a rail of the door frame at a junction between panes of the double pane door. The bracket forms a pair of recesses receiving the pair of extensions between the bracket and the rail when the main body is positioned for locking the doors. The bracket also has an opening for receiving the bolt when the bolt is placed in a locked position by action of the cylinder.
