Abstract
A control mechanism for opening and closing a window sash or like element pivotally mounted in a frame. The mechanism has a drive member mounted for rotation with an elongated drive shaft and a housing mounted on the drive member for rotation relative to the drive member and the elongated shaft. The housing includes a retaining mechanism which is subtended by a first portion of the drive member. A rod for reciprocating movement in response to rotation of the drive member is located between the retaining mechanism and the first portion of the drive member and held in direct contact with the drive member by the retaining mechanism. The rod has a first end attached to the window sash and also has cables connecting it to the drive member such that rotation of the drive member in a first direction causes longitudinal movement of the rod in a first direction, thereby opening the window, and rotation of the drive member in a second direction causes longitudinal movement of the rod in a second direction, thereby closing the window.
