ABSTRACT:
A panel in the form of a movable window frame hinged along its upper edge is swung from a closed position to an open position by a mechanism which includes a torque rod and crank-operated self-locking gearing to actuate the torque rod. A vibration damper in the form of a friction pad or brake shoe that engages the torque rod at a distance from the gearing, prevents chattering of the window when it is being swung towards its closed position and also resists any tendency for wind or vibration to oscillate the window.
