Abstract

A fenestration operation hardware assembly includes latch mechanisms configured for coupling to respective top and bottom sashes, and a paddle member configured for coupling the latch mechanisms. The latch mechanisms include movable latch bolts, and at least one of the latch mechanisms includes an operator interface feature movable between at least initial and operating positions. In an initial position, the latch bolts are in respective projected positions, and the top and bottom panels are immobilized. In a first withdrawn position, at least one of the top and bottom panels is movable, and in a second withdrawn position, at least one of the top and bottom panels is tiltable. In an example, a top latch bolt is moved by the paddle member according to movement of the bottom latch bolt.

Claims14

Dependent claims

A fenestration operation hardware assembly for a double hung window, the assembly comprising:

a first latch mechanism coupled with a first check rail of a first sash of the window and slidable together with the first sash within a frame, the first latch mechanism including a first latch bolt movable between a projected position and at least a first withdrawn position;
an operator device, operable by a user, to selectively move the first latch bolt between at least the projected position and the first withdrawn position;
a second latch mechanism coupled with a second check rail of a second sash of the window and slidable together with the second sash within the frame, the second latch mechanism including a second latch bolt movable between at least a projected position and a withdrawn position;
and
a transmission assembly within the frame, the transmission assembly substantially adjacent to the first and second check rails when the first and second sashes are in a closed configuration, and the transmission assembly operatively couples the first and second latch bolts in the closed configuration, and wherein movement of the first latch bolt by the operator device is transmitted to the second latch bolt through the transmission assembly.
