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: An actuator for use in fenestration systems having a swinging sash or door is characterized by the use of a linear member running continuously from an actuating assembly to a locking pin assembly. The linear member can be a flexible linear member, allowing it to convey motion to the locking pin assembly around corners. The locking pin assembly has a moveable locking pin with an actuator and an extension that can engage a keeper. The linear member has multiple actuator engagement sites along its length where the actuator of the locking pin can engage the linear member. The linear member can then be used to move the locking pin with respect to the locking pin assembly so that the extension can engage or disengage a keeper. The locking pin assembly can be mounted on a fenestration frame and the keeper opposingly mounted on a window or door mounted in the fenestration frame.
