Abstract
A window assembly includes a housing and a winder rotatably connected to the housing, where the winder includes a slot. The housing is mounted on a window sash. A flexible filament is disposed within the slot and is operative with the winder to withdraw window sash latches from a window frame so that the window sash can be removed from the frame.
Claims19
A window assembly comprising:
- a window sash slidingly mounted within a window frame, the window sash slides within a first plane;
- a housing mounted to the window sash;
- a winder rotatably connected to the housing and extending into an interior of the window sash, the winder being rotatable about a longitudinal axid thereof and having an opening extending therethrough, the opening having a longitudinal axis generally perpendicular to said longitudinal axis of said winder;
- and
- a flexible cord having a substantially round cross-section, the cord including two ends with each of said ends of the cord connected to a respective one of a pair of sash tilt latches, said cord extending through said opening such that as the winder is rotated in a first direction, the cord coils around the winder to draw the sash tilt latches inwardly, thereby releasing the window sash from the window frame, the cord having an outer cord diameter smaller than at least a portion of the opening such that the cord does not bind in and passes freely through the portion of the opening of the winder;
- wherein the winder has a distal end and a proximal end coupled with the housing, the winder having an intermediate portion therebetween.

A window assembly comprising:
- a housing mounted on an outer surface of a window sash, the window sash is mounted in a window frame and slides within a first plane;
- a winder rotatably connected to the housing and extending from the housing into an interior of the window sash;
- and
- a flexible filament connected to the latch elements and passing through an opening in a pair of tilt winder, and rotating the winder causes the filament to wrap around the winder to selectively draw the latch elements into the window sash, thereby permitting the window sash to be removed from the window frame, the filament having an outer diameter smaller than at least a portion of the opening such that the cord does not bind in and passes freely through the portion of the opening of the winder, the winder being rotatable about a longitudinal axis thereof which is parallel to said first plane.
