Publication number: 20100218425Abstract: 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.Type: ApplicationFiled: May 10, 2010Publication date: September 2, 2010Inventors: Douglas A. Nolte, Kenneth E. Best, Clark A. Velzke, Edward J. Subliskey, Anthony J. Rotondi

Patent number: 7676990Abstract: A sliding window having a pair of sashes with a latch mechanism on the meeting rail of one of the sashes for latching the sashes together. To open the window, the latch mechanism is disengaged by grasping a finger grip on a latch handle to retract a latch bolt. As one or more of the sashes is slid to open the window and the latch mechanism clears the meeting rail of the other sash, a trigger cam rotates so that a portion extends outward from the latch mechanism and another portion releases a spring tab to engage and hold the latch bolt in the retracted position. When the window is closed, the outwardly extending portion of the trigger cam contacts the meeting rail of the other sash, causing the trigger cam to rotate in the opposite direction and releasing the latch bolt.Type: GrantFiled: February 28, 2007Date of Patent: March 16, 2010Assignee: Truth Hardware CorporationInventors: William Bestler, Clark Velzke, Teressa Dickison

Publication number: 20090179436Abstract: A sliding window system can be equipped with a latch or lock mechanism. The lock mechanism can include a lock base mounted on a sliding sash of a window assembly opposite a keeper. The latch bolt of lock mechanism can be received in the keeper to latch the sashes together. A trigger is operably coupled with the latch bolt. To open the window, the lock mechanism is disengaged from the keeper by grasping a pull handle and pulling outwardly away from the window. As a result, the bolt moves to a retracted position within the lock base and a portion of the trigger extends out of the lock base, with the window capable of movement into an open position. When closing the window, the trigger contacts the keeper, releasing the bolt under the bias of a spring into the keeper, thus locking the window.Type: ApplicationFiled: November 10, 2008Publication date: July 16, 2009Inventors: Albert Sagalara, Clark Velzke, Glen Wolf

Publication number: 20070101653Abstract: A hinge assembly for a casement window including a track having a cam engaging portion defining a tri-lobular aperture, a sash arm pivotably and slidably coupled to the track, and a support arm pivotably coupled to the track on a first end and to the sash arm at the opposing end. An adjustable cam is operably connected through the support arm to engage the non-circular aperture within the track such that rotation of the adjustable cam selectively shifts the position of the support arm relative to the track to alleviate sash sag.Type: ApplicationFiled: November 7, 2005Publication date: May 10, 2007Inventors: Dan Bruzek, John Titus, Tim Frenzen, Clark Velzke

Patent number: 6848728Abstract: A window fastener for controlling the locking and unlocking of a window is disclosed. The fastener provides an unlocking feature that is manually activated by the user and a locking feature that is automatically activated as the window is moved substantially proximate to the closed position. The unlocking feature disengages the fastener from the window and maintains disengagement so that further manipulation of the fastener is not required to facilitate window opening. The fastener also provides a positive confirmation feature that informs the user that the window is either closed and locked or open and unlocked.Type: GrantFiled: April 1, 2003Date of Patent: February 1, 2005Inventors: Anthony Rotondi, Brian Dallmann, Tim Frenzen, Clark Velzke

Patent number: 5906403Abstract: A multipoint lock for securing a door to a door frame includes a tie bar longitudinally movable on the door with two latch members adjustably secured laterally relative thereto. The latch members are modular with hooks for selectively securing to the tie bar and other latch members. A metal face plate is securable over a door side groove with the tie bar movably secured to the plate in the groove at at least two locations by securing members extending through openings in the plate, tie bar and a plastic spacer. The securing members each include a longitudinal body member with parallel longitudinal sides cooperating with a tie bar slot to guide the tie bar. Rivets at ends of the securing members are secured to the plate. A link, pivotable about a substantially horizontal axis, has one arm driveably engaging the tie bar to selectively move the tie bar vertically toward a disengaged position.Type: GrantFiled: May 12, 1997Date of Patent: May 25, 1999Assignee: Truth Hardware CorporationInventors: William J. Bestler, Marcia K. Blom, Clark A. Velzke
