Abstract
Slide operator assemblies and components for fenestration units, as well as associated methods of manufacture and use thereof.
Claims16
A fenestration unit comprising:
- a frame including a head, a first jamb, a second jamb, and a sill;
- a sash hinged to the frame and configured to be movable 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 drive mechanism configured to impart an opening force on the sash toward the open position and a closing force on the sash toward the closed position;
- a slide mechanism, the slide mechanism being slidable;
- and
- a transfer mechanism operatively coupling the slide mechanism to the drive mechanism, the transfer mechanism including:
- a twisted wire coupled to the slide mechanism;
- the twisted wire configured to rotate in response to sliding motion of the slide mechanism;
- a spool attached to the twisted wire, the spool configured to rotate in response to rotation of the twisted wire;
- and
- a cord coupling the spool and drive mechanism, the cord configured to transfer force to the drive mechanism and to cause the drive mechanism to impart the opening and closing forces on the sash in response to rotation of the spool.

A fenestration unit comprising:
- a frame including a head, a first jamb, a second jamb, and a sill;
- a sash hinged to the frame and configured to be pivotably movable between an open position and a closed position;
- an operator assembly configured to transition the sash between the open and closed positions, the operator assembly including:
- a slide mechanism, the slide mechanism being slidable;
- a transfer mechanism operatively coupled to the slide mechanism and including a twisted wire on the sill configured to rotate in response to sliding motion of the slide mechanism;
- and
- a drive mechanism operatively coupled to the transfer mechanism and configured to impart an opening force on the sash toward the open position and a closing force on the sash toward the closed position, the drive mechanism including a carriage attached to the twisted wire, wherein the carriage is configured to move along a length of the twisted wire in response to the rotation of the twisted wire and a linkage assembly coupling the carriage to the sash.
