Abstract: An operator suitable for opening and closing casement windows includes a housing (e.g., a base and a cover), and an operator arm subassembly driven by a worm. The operator arm subassembly may include at least one operator arm pivotally disposed in the housing via a flanged bearing. The operator arm may define a gear. If a plurality of operator arms are present, a sun gear may be used. The flanged bearing properly aligns the components to reduce stresses encountered during use. The flanged bearing may have a base portion, a middle portion, and an upper portion in a stepped configuration. The base may engage the base of the housing. The upper portion of the bearing may engage a cover of the housing. A middle portion of the bearing pivotally joins the arm and/or sun gear. The instant flanged bearing provides a smoother, more efficient operation and increases the useful life of the operator.

Abstract: A multi-point sash lock assembly being shiftable between a locked and an unlocked disposition includes a tie bar assembly including a tie bar guide, the tie bar guide having at least one guide end, the guide end being integrally, unitarily formed. A multi-point sash lock assembly for securing a rounded side of a window to a rounded window frame and a method of forming a multi-point sash lock assembly are further included.

Abstract: A latch apparatus includes a live bolt actuated between an extended position and a retracted position, first and second dead bolts, and a slide. The first dead bolt is positioned vertically above the live bolt and the second dead bolt is positioned vertically below the live bolt. The first and second dead bolts have substantially the same size and shape and are spaced equidistant from the live bolt. The slide couples the first and second dead bolts to each other, wherein vertical movement of the slide simultaneously actuates the first and second dead bolts between extended and retracted positions.

Abstract: A projection window operator providing horizontal displacement of a window relative to a vertical plane of the frame of the window. With at least one projection window operator installed on each of opposing sides of the window, the window can be actuated between a first closed position and second open position in which a trickle ventilation is provided around the window. The projection window operators installed on the window can be interconnected for simultaneous actuation, or actuated individually, providing selective ventilation on either side.

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.
