Abstract: An electrical linkage assembly for a window or door includes a frame mount, a sash mount, a first link arm, and a second link arm. A first pivot joint is formed between the frame mount and the first link arm, a second pivot joint is formed between the first and second link arms, and a third pivot joint is formed between the second link arm and the sash mount. One or more electrical wires extend from the frame mount, through the first and second link arms and each of the first, second, third pivot joints, fully enclosed therein, and out of the sash mount.

Abstract: A sash limiter assembly for limiting the distance a casement window can be opened. In a jamb mounted version, the limiter is mounted in one constant location on the jamb rather than multiple locations on the sill which results in the opening distance being essentially the same for all window widths and all hinge types. In both the jamb mounted version and a sill mounted version, a hexalobular or other security screw can be used to retain a limiting arm to a stud attached to a bracket, or a stud attached to a slider which slides on a track to inhibit unauthorized removal of the limiter arm.

Abstract: An integrated casement window operator and lock, including a gear mechanism and an arm assembly, the arm defining a rack portion and an adjacent arcuate gear portion, the arm mounted to the housing with a pinion gear engaged with the rack portion and the arcuate gear portion, the pinion gear defining a star-shaped aperture therethrough and a handle with a square-shaped shaft portion received in the star-shaped aperture of the gear. The handle is selectively rotatable to shift the arm between a window fully closed position and a window fully open position, wherein an anti-backdrive mechanism is provided to inhibit backdriving of the arm in both the window fully closed window fully open positions.

Abstract: A sash lifter assembly for a casement to equalize the amount of reveal at the top and bottom of the casement window sash, and that is also adjustable to accommodate manufacturing tolerances. The sash lifter raises the entire sash up to equalize the reveal at the top and bottom of the window. It is adjustable to accommodate the variation in reveal due to manufacturing tolerances.

Abstract: Power window operators and windows incorporating the power window operators are described herein. The power window operators include both a guide pin and guide pin slot, as well as a pivot pin and pivot pin slot to control movement of an operator arm.

Abstract: A lock for a window which includes a body including a channel defined in an interior of the body, an actuator element configured to be received in the channel and slidable therein, the actuator element including a fork portion to operably couple with a tie bar assembly for locking the window, a handle pivotally coupled to the actuator element, and a linkage pivotally coupled between the body and an intermediate point on the handle. The handle is movable between a closed position and an open position, with movement of the handle causing the actuator element to slide within the channel in a direction opposite the direction of movement of the handle.

Abstract: A key lockable window operator, including a crank handle that is shiftable between a folded storage position and an unfolded operating position and a lock cylinder operably engaged to a rack and a sliding pin. The rack and the sliding pin are shiftable between an unlocked position and a locked position. When in the locked position, at least a portion of the sliding pin is engaged into a cavity in the crank handle whereby the crank handle is secured in the folded storage position.

Abstract: An around-the-corner locking mechanism is mounted using known tie-bar guides so as to cause a self-locating feature for the device on a casement or awning window. The device has an adjustable connecting link so that standard lock system tie bars can be used at industry standard spacings, while also being adaptable to custom sized windows. The mechanism, through an around-the-corner component, has tie bars integrated directly into the around-the-corner component so as to provide a locking point on a casement window jamb at a nearly constant distance from the head or sill of the window, and another linked locking point on the head or sill itself. The tie bars in the around-the-corner component can be linked through an adjustable length linking component to a driving tie bar and slave tie bars to provide still more locking points.

Abstract: A locking mechanism for use with a window having a hinge coupling a sash to a frame includes a keeper and a locking lug. The keeper includes a generally planar base plate that is abutable to a surface of either the sash or the frame and two wings extending upwardly from the base, each of the wings having an upwardly and inwardly extending portion extending from the base plate and an inwardly extending portion extending inwardly substantially parallel to the base plate from the upwardly and inwardly extending portion. The two inwardly extending portions define a gap therebetween. The planar base further includes at least one self locating leg extending outward and coplanar with the base. The self locating leg adapted to abut a portion of the sash or the frame. Thus, the keeper is positionable without a fixture.

The rack and the sliding pin are shiftable between an unlocked position and a locked position. When in the locked position, at least a portion of the sliding pin is engaged into a cavity in the crank handle whereby the crank handle is secured in the folded storage position.
