Abstract: A low-cost combination tilt-lock-latch mechanism for a sliding window that combines ease of installation and adjustment with simplicity of use. The mechanism includes at least one tilt-latch mechanism adapted for mounting in the window sash. The tilt-latch mechanism includes a housing and a plunger having a latch bolt portion retractable within the housing. A plunger latch member automatically latches the plunger in a retracted position to enable tilting of the sash. Further, the mechanism may include an actuator mechanism and a flexible linking member. The tilt-latch may include a locking member adjustable from outside the housing of the tilt latch, to lock the flexible linking member to the plunger, thereby operably coupling the actuator mechanism with the tilt-latch.

Abstract: A handle that is extendable and retractable to minimize interference with window decorations and having a feature, which allows removal and attachment of the handle from the crank of the window operator without the use of tools. The handle is removable from the window operator though the use of either a clip lock feature or a spring lock clip both of which can be top down assembled with the minimum of effort and complexity.

Abstract: An actuator having a housing with a pivot opening therein. An actuator handle has a pivot pin extending from an end thereof for connecting the handle to a crank which includes a drive pin. The handle is assembled to the housing with the pivot pin extending through the pivot opening. A bushing may be disposed between the pivot pin and the pivot opening to take up tolerances between the parts and provide smooth handle rotation. The drive pin on the crank extends into a drive slot on a slider which translates within the housing to actuate a window locking mechanism. The drive slot is generally pear-shaped with, preferably symmetrical, opposed curved sidewalls along which the drive pin rides during rotation of the handle. The slider may further include a pair of fulcrum tabs disposed on a top thereof adjacent opposite sides of the drive slot for contacting a side surface of the crank during rotation of the handle to provide mechanical advantage at the handle.

Abstract: A check rail lock securable to the top rail of one window sash of a double hung window, including a housing, a cam pivotable about a first axis within the housing between an open position and a locking position, a pin extending from the bottom of the cam, and a guard member disposed substantially beneath the cam and pivotable about a second axis within the housing, the guard member having a slot receiving the pin for moving between a guarding position and a retracted position responsive to pivoting of the cam between the locking position and the open position. The cam in the locking position includes a portion extending from the housing and adapted to cooperate with a keeper secured to the other window sash to lock the one window sash in a closed position relative to the other window sash. The guard member extends from the housing to substantially overlap with the cam extending portion in the guarding position and the guard member is substantially entirely retracted into the housing in the retracted position.

Abstract: An improved deadbolt lockset is provided in which one of two different backset distances is facilitated in a single latch assembly. At least one planar side plate coupled to a deadbolt extension is provided and is slidably contained within a hollow latch case. Movement of the side plate determines the distance from the face plate of the assembly to the axis of an actuating assembly. The latch case includes slots formed therein for positioning the actuating assembly and to allow movement of the side plates.

Abstract: A latch mechanism is provided in which one of two different backset distances is facilitated in a single latch assembly. A latch slide which is used to retract the latch bolt of the assembly is provided with a removable latch slide extension which determines the distance from the face plate of the assembly to the center of the actuating assembly. The latch slide and bolt are carried within a latch case or housing which includes slots formed therein. The actuating assembly includes jaws which fit into the slots in order to fix the position of the latch assembly with respect to the actuating assembly upon final installation of the mechanism into the door.

Abstract: An L-shaped guard plate for reinforcing a door in the area of the door lock assembly. The L-shape provides a strengthening function without introducing any misalignment in the position of the lock bolt of a door with respect to the strike plate carried in a door frame. The device is thus both effective and easily installed on most doors. The guard plate may include integral tabs which engage slots in the housing of the lock unit. The tabs serve to provide increased resistance to the application of rotational forces to the lock unit.
