Tilt latch apparatus and sashes incorporating the same are described herein. The tilt latch apparatus tilt latch apparatus may provide a convenient mechanism for a user to release the tilt latches on a sash with one hand while controlling movement (e.g., rotation) of the sash with another hand.

An adjustable stop limits sliding sash window/door travel between a closed position and a safe position, where the safe position is a position less than a full-open position. The stop can be installed upon window/door master frames during initial manufacturing, or as an after-market option while the sash windows/doors are in service in a building. The safety stop may be comprised of a housing and a tumbler being pivotally mounted within a cavity in the housing, with a spring to bias the tumbler out of an opening in the housing. Mounting is by a flange extending from the housing, with spacers of varying thickness that are capable of removably attaching thereon to accommodate sash to master frame height differences. A safety member may be added to either the tumbler or housing to create a double action stop, requiring disengagement of the safety member, prior to toggling of the stop.

A mountable interlock security device for securing first and second sliding articles slidable relative to each other from an open position to a closed position such that in the closed position the sliding articles have overlapping interior edges. The security device comprises a first component mountable to the first sliding article and a second component mountable to the interior edge of the second sliding article. The two components of the security device are mounted to the overlapping end regions of respective sliding articles such that when the sliding articles are in the closed position, the two components of the security device cooperate to limit lateral movement of the sliding articles. In another aspect, a method of retrofitting interior and exterior sliding articles, such as doors or windows, of a building with a security device is provided.

A window assembly is disclosed including a window casing; a sash assembly slidably mounted within the window casing, the sash assembly including first and second stiles extending between first and second rails; a first tilt latch assembly mounted in the first stile; a second tilt latch assembly mounted in the second stile; and a sash lock mounted to the first rail, the sash lock being operably connected to the first and second tilt latch assemblies to operate the first and second tilt latch assemblies between a latched position in which a latch member of each of the first and second tilt latch assemblies engages with the window casing assembly and an unlatched position in which the latch member of each of the first and second tilt latch assemblies is disengaged with the window casing assembly.

A lock assembly is provided for a window having a first sash and a second sash. The lock assembly comprises an elongate strip configured to be coupled to the first sash. The elongate strip has a plurality of recesses defined along a length of the elongate strip. The lock assembly also includes a lock member configured to be coupled to the second sash and operable to move along the length of the elongate strip. The lock member includes a biasing member and a coupler biased in a direction of the elongate strip by the biasing member. The coupler is configured to enter each of the plurality of recesses to selectively lock the lock member to the elongate strip.

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 sliding sash assembly for use as a door or window includes: (a) a frame defining a frame opening; (b) a pair of sashes mounted in the frame opening and slidable relative to each other along an opening axis between a closed position and an open position; and (c) at least one stop device including a housing and a pair of depressible stop members movably mounted in the housing. The stop members are spaced apart from each other along the opening axis. Each stop member is selectively movable independent of the other stop member between a retracted position in which the stop member is retracted into the housing and an advanced position in which the stop member projects from the housing for engagement with one of the sashes to restrict movement of the sashes relative to each other toward the open position.

A lock kit for a fenestration assembly includes a panel stop. The fenestration assembly includes a first panel and a second panel, at least one of the first and second panels being slideable relative the other of the first and second panels. The panel stop is configured to pivotably mount within a recess of a frame member of the first panel and pivot between a first stop position configured to maintain the first and second panels in a fully closed position, a second stop position configured to limit sliding of the first and second panels beyond a preset partially-open position, and a third position substantially within the recess, the third position being configured to not restrict a range of motion of the first and second panels.

A sash lock for a sash window assembly is disclosed. The sash window assembly includes an upper sash window and a lower sash window. Each of the sash windows is mounted within opposed guide rails on a master frame. At least one of the sash windows is slidable within the frame relative to the other sash window. The sash lock comprises either a keeper, with a keeper opening, for mounting on a rail of one of the sash windows or a recess in the lower rail of the upper sash. The sash lock disclosed herein includes a housing having a hole, an actuator arm, and a cam having a cam element for receipt into the keeper opening or the recess. The locking assembly also includes a shaft extending through the housing hole and operably coupling the actuator arm to the cam.

A sash window fastener includes: a latch assembly; a sash lock assembly mounted upon the meeting rail; and a stop member mounted to the master window frame. The lock assembly includes a pivotable cam to engage a keeper on the master frame to lock the window, and a pivotable follower arm. The arm interconnects with the latch assembly within the meeting rail, so cam rotation that drives arm rotation also causes translation of the latch. The cam may occupy: an extended position to secure the cam to the keeper, with the latch engaging the master frame to prevent tilting, and being positioned below a protrusion on the stop member to redundantly lock the window; a first retracted cam position permitting sliding of the window; and a second retracted position permitting tilting of the sash window. Additional protrusions may be used on the stop member to serve as vent stop positions.
