Double hung operation hardware

摘要

A fenestration operation hardware assembly includes at least one latch mechanism and an operation hardware assembly configured for coupling with a panel slidable within a frame. The latch mechanism includes a latch bolt and a latch biasing element coupled with the latch bolt. An operator of the operation hardware assembly is remote from the latch mechanism and is coupled with the panel. The operator includes an operator interface feature movable between initial and operating positions. In the initial position the latch bolt is in a projecting position, and in the operating position the operator interface feature moves the latch bolt into one or more withdrawn positions. The operation hardware assembly includes a retention assembly for retaining the latch bolt in a withdrawn position.

1. A fenestration operation hardware assembly comprising:
at least one latch mechanism, the latch mechanism is configured for coupling with a sash slidable within a frame, the latch mechanism includes a latch bolt movable between a withdrawn position and a projecting position, the withdrawn position allowing sliding movement of the sash relative to the frame with the latch bolt received within a sash groove of the frame, and the projecting position limiting at least sliding movement of the sash within the frame with the latch bolt received within a locking recess; an operator remote from the latch mechanism, the operator is configured for coupling with the sash, the operator includes:
an operator interface feature movable between at least initial and operating positions, in the initial position the latch bolt is in the projecting position and received within the locking recess, and in the operating position the operator interface feature moves the latch bolt into the withdrawn position and the latch bolt is received in the sash groove, andan operator mechanism coupled with the operator interface feature, the operator mechanism includes a retention assembly coupled with the operator interface feature in at least the operating position, and in the operating position the retention assembly retains the operator interface feature in the operating position and accordingly the latch bolt in the withdrawn position with the latch bolt in the sash groove; and a tying element coupled between the operator mechanism and the latch bolt, wherein operation of the operator interface feature is transmitted to the latch bolt through the tying element.
