Patent number: 5937582Abstract: A rotary window operator to effect opening and closing of a window. A rotatable handle (14) is mounted on a housing (10) from which a link member (16) projects. The handle (14) is pivotally coupled to a cage (29) in which a bush (30) is slidingly engaged. A cam surface (25) of handle (14) forces teeth on bush (30) to engage with teeth of cage (29) when the handle (14) is pivoted from a non-use position to an in-use position. A drive shaft coupled to the bush (30) has a gear which meshes with gear wheel (18) of link member whereby rotation of the handle (14), when in the in-use position, imparts movement in link member (16).Type: GrantFiled: June 21, 1996Date of Patent: August 17, 1999Assignee: Interlock Industries LimitedInventor: Nigel Alan Colebrooke Taylor

Patent number: 5802913Abstract: A casement and awning window operator consisting of four parts, a top cover, a base, a worm gear receivable in a pocket on the base and top and a geared actuating arm engaging the worm gear having an integral arm extending out of the operator. The cover is secured to the base by an adhesive applied to matching surfaces of the cover and base trapping the worm gear therein. The cover and base are made from two plastic halves in a generally horizontal parting plane thus presenting a large adhesive contact area in a plane putting the contact surfaces in shear and allowing insertion of the gear and arm prior to assembly. The cover and base may have molded parts providing a spring-like effect to control the friction of the operator to prevent it from rotating out of a set position.Type: GrantFiled: May 19, 1997Date of Patent: September 8, 1998Inventor: Kurt W. Winner

Patent number: 5590491Abstract: An operator for controlling pivoting of a window sash relative to a window frame including dual arms which pivot relative to one another to move the window sash. A drive input pivotally drives a drive member which is eccentric about its pivot axis, where the drive input includes recesses spaced from the input pivot axis and engageable by a user's fingers to manual pivot the drive input. A drive ring gear is pivotable relative to the drive member and includes two axially spaced sets of gear teeth. The dual arms are secured to separate ring gears which are respectively associated with the two gear teeth sets. The drive ring gear is moved eccentrically relative to the pivot axis by the eccentric drive member whereby at least some of the teeth of the first set of drive ring gear teeth are disengaged from the teeth of its associated arm ring gear and at least some of the teeth of the second set of drive ring gear teeth are disengaged from the teeth of its associated arm ring gear.Type: GrantFiled: October 24, 1994Date of Patent: January 7, 1997Assignee: Truth Hardware CorporationInventor: Stephen M.

Patent number: 5509234Abstract: An operator assembly for a casement window that includes a frame and a pane carrying sash. The operator assembly is mounted to the frame and an elongated arm connects the operator assembly and the sash. Movement of the arm moves the sash relative to the frame for opening and closing the window. The operator arm includes a pivotally mounted and linerally moveable handle which is moveable between a first and second position. A ratchet-type gearing system is provided to connect the handle and operator arm and to effect movement of the operator arm in response to movement of the handle. A selector associated with the handle and gearing system is provided to effect and control the direction of sash movement in response to the movements by the handle. A locking system is provided to engage the gearing system to prevent movement of the gearing system due to loads on the sash that are transmitted to the gearing system through the sash and operator arm.Type: GrantFiled: September 16, 1994Date of Patent: April 23, 1996Assignee: SNE Enterprises, Inc.Inventors: David J.
