Rotary bearing arrangement on pane frame of round or oval window - comprises fixed part on which loose part is rotatably held with flat surfaces on outer peripheral surface of hollow profile in application area of loose part aligned to curvature

摘要

The hollow profile (1) has ribs (3,4) on a peripheral surface (2) which is convexly curved and turned away from the centre of the round or oval window. Between them they form a back-cut groove (5), in which a slide (6) of a closure mechanism is longitudinally displaceable and the free ends of the ribs in the application area of the loose part (12) are flattened (7,8). The slide (6) in the area of the rotary bearing (10) has a longitudinal hole (13) and the base of the back-cut groove (5) in the area under the hole (13) is flattened. USE/ADVANTAGE - A sure and fixed arrangement of a mass-produced rotary bearing for the pane frame of a round or oval window.
