Abstract
An integrated casement window operator and lock mechanism including an arm shiftable with a lever handle between a first position of the lever handle wherein the window is closed and the sash is locked to the frame with a hook defined in an arm of the operator and lock mechanism, a second position wherein the hook is disengaged so as to unlock the sash from the frame, and a third position wherein the arm is pivoted outward to move the sash out of the frame, thereby opening the window.
Claims18
An integrated casement window operator and lock, comprising:
- a gear mechanism, the gear mechanism including a housing, a pinion gear rotatably mounted to the housing, and an arm assembly including an arm and a sash interface, the arm defining a rack portion and an adjacent arcuate gear portion, the arm slidably and rotatably mounted to the housing with the pinion gear engaged with the rack portion and the arcuate gear portion, the arm further defining a hook portion, the sash interface including a track and a shoe slidably coupled with the track, a distal end of the arm pivotally coupled with the shoe;
- and
- a handle directly fixed to the pinion gear, wherein with the housing of the gear mechanism adapted to be mounted on a frame of a casement window, and the track of the gear mechanism adapted to be mounted on a sash of the casement window, the handle is selectively movable to rotate the pinion gear such that the arm is shifted between a window locked position wherein the sash of the casement window is received in the frame of the casement window and the hook portion is engaged with a lug attached to the frame of the casement window so as to retain the sash in engagement with the frame, a window unlocked position wherein the arm is shifted relative to the housing such that the hook is free from engagement with the lug, and a sash open position wherein the arm is rotated relative to the housing urging the sash to be swung outward from the frame.
A casement window, comprising:
- a frame defining an opening;
- a sash received in the frame and hinged to the frame to selectively close the opening;
- and
- a window operator and lock, the window operator and lock comprising:
- a gear mechanism, the gear mechanism including a housing, a pinion gear rotatably mounted to the housing, and an arm assembly including an arm and a sash interface, the arm defining a rack portion and an adjacent arcuate gear portion, the arm slidably and rotatably mounted to the housing with the pinion gear engaged with the rack portion and the arcuate gear portion, the arm further defining a hook portion, the sash interface including a track and a shoe slidably coupled with the track, a distal end of the arm pivotally coupled with the shoe;
- and
- a handle directly fixed to the pinion gear, wherein the housing of the gear mechanism is mounted to the frame of the casement window, and the track of the gear mechanism is mounted to the sash of the casement window, the handle is selectively movable to rotate the pinion gear such that the arm is shifted between a window locked position wherein the sash of the casement window is received in the frame of the casement window to close the opening and the hook portion is engaged with a lug attached to the frame of the casement window so as to retain the sash in engagement with the frame, a window unlocked position wherein the arm is shifted relative to the housing such that the hook is free from engagement with the lug, and a sash open position wherein the arm is rotated relative to the housing urging the sash to be swung outward from the frame.
