Abstract: A low profile actuating window lock for casement windows having a handle actuate a lifter that slides vertically on a fork component in slidable communication with the window lock casing, the handle pivotable about the lifter and pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle, lifter, restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

Abstract: The invention relates to a lock mechanism for a casement window having a keeper adapted to be attached to a sash, a lockbar adapted to be attached to a frame for engaging with the keeper to lock the casement window, and an actuator for actuating the lockbar to engage with the keeper. The actuator includes a fork having a V shaped groove, the V shaped groove includes a first leg and a second leg, and the actuator includes a switch having a channel for placement of a drive pin. The switch is rotatably mounted at a juncture of the first and second legs so that the channel generally aligns with either the first leg or the second leg for facilitating alignment of the drive pin within the V shaped groove.

Abstract: A roller pin of the type mounted on a tie bar that slides to drive the roller pin into engagement with a keeper of a casement window includes an inner pin and an outer roller. The outer roller includes an integral outer flange that is circular and spins with the outer roller to reduce friction during engagement with keeper. The inner pin includes an offset mounting pin at one end and is enlarged at the other end to hold the outer roller on the inner pin. The enlarged end of the inner pin is flush with the outer flange and is provided with a recessed opening that receives a tool, such as a screwdriver, to rotate the inner pin and adjust its position relative to the tie bar and a keeper. The invention is also directed to a tie bar and multiple roller pins in combination.

Abstract: The invention relates to a lock for a window having a button and a spring for biasing the button to move from an unlocked position to a locked position; a spring clip in contact with the button for holding the button in the unlocked position; a trigger for engaging with the spring clip to release the button and allow the spring to move the button toward the locked position; a hook for moving from an unlocked position to a locked position in correspondence with the button moving from the unlocked position to the locked position; and a rotatable arm with one end attached to the button and another end attached to the hook, the rotatable arm for transmitting a movement of the button to a movement of the hook. A magnet is attached to the trigger and the magnet is moved, which in turn actuates the trigger, by a polarity of another magnet.
