Abstract
Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.
Claims14
A fenestration unit comprising:
- a frame having a head, a first jamb, a second jamb, and a sill;
- a sash hinged to the frame such that the sash is pivotable between an open position and a closed position;
- and
- an operator assembly configured to transition the sash between the open and closed positions, the operator assembly including,
- a rotary drive mechanism configured to rotate to impart an opening force on the sash toward the open position and a closing force on the sash toward the closed position, and
- a slide mechanism operatively coupled to the drive mechanism, the slide mechanism being slidable to cause the drive mechanism to impart the opening force and the closing force, respectively, on the sash, the slide mechanism being associated with the frame and including a handle that is linearly slidable along the frame;
- and
- a transfer mechanism operatively coupling the slide and drive mechanisms such that a first, linear input to the handle of the slide mechanism along a first axis is transferred along a second axis as a linear input force on the rotary drive mechanism.
