(57) Slide brake (11) for turnable windows, doors or shutters, which windows, doors or
shutters consists of a frame (1), with one lower part (2), one upper part (3) and
two lateral parts (4). In those lateral parts a casement (5) for instance a window
casement, is pivoting suspended by two mirror symmetrical equal swinging arm assemblies
(6). The lateral parts (4) of the frame includes each at least one slide groove (7),
in which a slipper (10) is provided to slide with a certain friction. This slipper
(10) is in turn articulated attached to the upper element (8) of the window casement,
via the upper assembly (9) on the respective short side of the upper element. The
friction between the slipper (10) and its surrounding surfaces are larger in at least
one subarea, in the slide groove (7), compared to the friction in other parts of the
slide groove (7), by that the slide groove (7) in the subarea comprises a constriction,
which brakes the slipper (10) in the subarea, whereby a continuously and automatically
disengageable airing blocking device is obtained.
