Abstract
Hinged window drive systems and window assemblies incorporating them provide for a combination of powered or motorized operation in addition to manual operation using a hand crank, with the opportunity for a user to switch between motorized operation and manual operation as needed.
Claims13
A hinged window assembly comprising:
- a movable sash attached to a window frame such that the movable sash can be rotated to open and close the movable sash relative to the window frame;
- a linkage connected to the window frame and the movable sash;
- and
- a drive system operably connected to the linkage, wherein the drive system and the linkage are configured to rotate the movable sash relative to the window frame, wherein the drive system comprises:
- a linkage driver fixedly mounted on a drive shaft, wherein the drive shaft defines a drive shaft axis extending along a length of the drive shaft, wherein rotating the drive shaft about the drive shaft axis rotates the linkage driver about the shaft axis, and wherein rotation of the linkage driver operates the linkage such that the movable sash rotates relative to the window frame;
- a motor apparatus comprising an output shaft;
- a motor coupling apparatus operably connected to the drive shaft and the output shaft, wherein the motor coupling apparatus is configured to selectively couple or decouple the output shaft and the drive shaft;
- a hand crank coupling apparatus operably connected to a hand crank gear, wherein rotation of the hand crank gear about the drive shaft axis rotates the drive shaft when the hand crank coupling apparatus is in a manual configuration in which the hand crank gear is operably connected to the drive shaft;
- a hand crank apparatus configured to rotate about a crank axis which is angled relative to the drive shaft axis, and wherein rotation of the hand crank apparatus about the crank axis rotates the hand crank gear about the drive shaft axis when the hand crank apparatus engages the hand crank gear;
- and
- a selector mechanism configured to move the hand crank gear in translation along the drive shaft axis to selectively engage the hand crank apparatus with the hand crank gear when the hand crank coupling apparatus is in the manual configuration, wherein the selector mechanism also selectively couples and decouples the output shaft and the drive shaft, wherein the hand crank coupling apparatus is in the manual configuration when the output shaft is decoupled from the drive shaft.

- a linkage driver fixedly mounted on a drive shaft, wherein the drive shaft defines a drive shaft axis extending along a length of the drive shaft, wherein rotating the drive shaft about the drive shaft axis rotates the linkage driver about the shaft axis, and wherein rotation of the linkage driver operates the linkage such that the movable sash rotates relative to the window frame;
- a motor apparatus comprising an output shaft;
- a motor coupling apparatus operably connected to the drive shaft and the output shaft, wherein the motor coupling apparatus is configured to selectively couple or decouple the output shaft and the drive shaft;
- a hand crank gear operably coupled to the drive shaft;
- a hand crank apparatus comprising a hand crank and a drive gear configured to rotate about a crank axis which is angled relative to the drive shaft axis, wherein rotation of the hand crank about the crank axis rotates the drive gear about the crank axis, and wherein rotation of the drive gear about the crank axis rotates the hand crank gear and the drive shaft about the drive shaft axis when the drive gear engages the hand crank gear;
- and
- a selector mechanism configured to move the hand crank gear in translation along the drive shaft axis to selectively engage and disengage the hand crank gear and the drive gear, wherein the selector mechanism also selectively couples and decouples the output shaft and the drive shaft, wherein the hand crank gear is engaged with the drive gear when the output shaft is decoupled from the drive shaft.
