IMPROVEMENTS IN OPERATING MEANS FOR PIVOTED WINDOWS

摘要

Operating means for a window including a horizontally pivoted panel comprises an elongated torque tube extending parallel to the panel pivot axis. A torque-transfer element is pivotally connected to the torque tube for movement relative thereto about a primary transverse axis and an operating crank, which is drivingly connected to the torque-transfer element, is arranged for rotation relative to a horizontal axis at right angles to the axis of the torque tube.
