Casement window operator |
摘要 |
A casement window operator includes a linkage with an extensible arm pivotally connecting to a driven arm mounting to the window frame. An extended end of the driven arm pivotally connects to a link mounting to the sash bracket on the pivoting sash. The extensible arm includes a screw drive member connected to a friction bearing of a cover. Rotation of the screw extends and retracts the cover to lengthen and shorten the extensible arm. The operator includes an actuator with a handle mounted to a first bevel gear intermeshing with a second bevel gear. The bevel gears are mounted in a housing which pivotally rotates as the linkage is actuated. The second bevel gear is coupled to the screw member of the extensible arm.
