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.

A cover and folding handle assembly for rotating the drive input member of a window operator to open and close a window, including a handle base drivingly engaging the drive input member and an elongate handle having a first end pivotally connected to the handle base so that the handle is movable between an extended position in which the handle is operable to rotate the drive input member and a folded storage position in which the handle overlies the handle base. An opening in the second end of the handle is aligned with an opening in a knob, and an axial pin has a first end received in one of the aligned openings and a second end received in the other of the aligned openings. A rotatably fixed end of the pin is frictionally secured in one of the openings, and the other pin end is received in a sleeve frictionally secured in the other opening and securing a pin head in that opening. The cover has an opening through which the drive input member on the window operator extends. A retainer is securable to the operator through a first undercut tab engaging a locking groove on the operator. The cover has a groove adjacent to its opening snappingly receiving an undercut end of a second retainer tab extending through the cover opening. The cover also has a slot and the retainer has a tab engaged with the slot for preventing rotation of the cover relative to the operator base.
