Abstract
A window operator assembly comprises a leadscrew and an elongated nut. The leadscrew is pivotally connected to a window frame via a frame pivot and is rotatable relative to the window frame. The elongated nut is pivotally connected to a window sash via a sash pivot. As the leadscrew rotates in a first direction, the elongated nut moves in a first direction along the leadscrew and moves the window sash toward an open position relative to the window frame. As the leadscrew rotates in a second direction, the elongated nut moves in a second direction along the leadscrew and moves the window sash toward a closed position relative to the window frame.
Claims19
A window operator assembly for moving a window sash between an open position and a closed position relative to a window frame, the window sash having a top sash member operatively connected to a bottom sash member by a first side sash member and a second side sash member, the window frame having a top frame member operatively connected to a bottom frame member by a first side frame member and a second side frame member, the window operator assembly comprising:
- a leadscrew pivotally operatively mounted to the window frame via a frame pivot and rotatable relative to the window frame;
- and
- an elongated nut pivotally mounted to the window sash via a sash pivot, wherein as the leadscrew rotates in a first direction, the elongated nut moves in a first direction along the leadscrew and moves the window sash toward the open position relative to the window frame, and as the leadscrew rotates in a second direction, the elongated nut moves in a second direction along the leadscrew and moves the window sash toward the closed position relative to the window frame, wherein the leadscrew and the elongated nut interconnect the window frame and the window sash and the window sash partially pivots relative to the window frame about the sash pivot, and the sash pivot moves relative to the window frame as the window sash moves with the elongated nut relative to the window frame.
A window operator assembly for moving a window sash between an open position and a closed position relative to a window frame, the window sash having a top sash member operatively connected to a bottom sash member by a first side sash member and a second side sash member, the window frame having a top frame member operatively connected to a bottom frame member by a first side frame member and a second side frame member, the window operator assembly comprising:
- a leadscrew having a first leadscrew end and a second leadscrew end;
- a motor operatively connected to the first leadscrew end and configured and arranged to rotate the leadscrew;
- a first pivot configured and arranged to pivotally mount the leadscrew to the window frame;
- an elongated nut having a first nut end, a second nut end, and a bore extending longitudinally through the elongated nut, the bore configured and arranged to receive at least a portion of the leadscrew, the elongated nut being configured and arranged to move along the leadscrew when the leadscrew is rotated by the motor;
- and
- a second pivot configured and arranged to pivotally mount the elongated nut to the window sash, wherein the leadscrew and the elongated nut interconnect the window frame and the window sash and the window sash partiallu pivots relative to the window frame about the second pivot, and the second pivot moves relative to the window frame as the window sash moves with the elongated nut relative to the window frame.
An operator for moving a window sash between a closed position and an open position relative to a window frame, comprising:
- a leadscrew having a first leadscrew end and a second leadscrew end;
- a rotating member operatively connected to the first leadscrew end and configured and arranged to rotate the leadscrew;
- a first pivot configured and arranged to pivotally mount the leadscrew to the window frame;
- an elongated nut having a first nut end, a second nut end, and a bore extending longitudinally through the elongated nut, the bore configured and arranged to receive at least a portion of the leadscrew, the elongated nut being configured and arranged to move along the leadscrew when the leadscrew is rotated by the rotating member;
- and
- a second pivot configured and arranged pivotally mount the elongated nut to the window sash, wherein the leadscrew and the elongated nut interconnect the window frame and the window sash and the window sash partially pivots relative to the window frame about the second pivot, and the second pivot moves relative to the window frame as the window sash moves with the elongated nut relative to the window frame, wherein a distance between the first pivot and the second pivot shortens to position the window sash in the open position relative to the window frame and the distance between the first pivot and the second pivot lengthens to position the window sash in the closed position relative to the window frame.
