Rotating bearing with stop for window frames - has spring loaded low wear non return plug with actuating handle

摘要

The rotating bearing is used for revolving windows and the angle of opening is restricted by a stop which is released. The stop is actuated for preventing return rotation and has low wear and relatively simple design. The stop is immediately ready for blocking window return after window has passed over it. The nonrotating stop plug (16) is moved in axial direction under a spring force. The internal end (17) has actuating face (29) for engaging with the blocking holt edges. The external end (21) has operating handle (24) engaging with guide slot (22) of the stop plug. This handle engages in released position on the rotating bearing.
