(57) In a window or door arrangement for a building facade, a sliding window or a sliding
door is mounted side by side with a fixed building element, e.g. a window or panel
portion, such that in the closed position, the mobile sash of the sliding window or
door (48) is flush with the fixed building element.
By means of displacement fittings comprising a trolley (54, 55) which is supported
in a longitudinally displaceable way by a guide rail (53) fastened to the bottom member
(52) of the frame structure and is connected by parallel carrier arms (56, 57) to
the mobile sash (48), the mobile sash can move by translatory motion to a start location
in the displacement plane for subsequent sideways displ-acement therein towards an
open position, in which it overlaps the fixed building element.
Releasable retaining means (65, 70) assure that the sash (48) during the sideways
displacement is retained in the displacement plane.
By the translatory motion between the closed position and the start location in the
displacement plane, the sash (48) is secured against sideways displacement towards
collision with the fixed building element.
