Abstract: The invention relates to a pivotable glazing for a balcony. There are previously known balcony glazings which comprise four or more panes which move in an overlapping manner on two adjacent tracks. Such a structure requires considerable sealing and frame structures which detract from the outer appearance of the building. Furthermore, the balcony aperture can be opened at maximum 50%, and it is difficult to wash the outer surfaces of the panes. According to the present invention, these disadvantages are eliminated by fitting all the panes of glass adjacently in the same double-rail track. At the upper edge of each movable glass pane (1) there are two slides (3, 4), of which one moves on a straight outer rail and the other on an inner rail, which curves inwards and towards the side wall (13) of the balcony. Within the curved portion (18) of the inner rail the trailing edge of the pane turns inwards and the pane can be opened against the side wall (13) of the balcony.

Abstract: An operable wall system having a primary track and several storage tracks intersecting said primary track can be improved by the use of rotary switches at the intersections of the primary and storage tracks and by the use of a positioning structure carrying holders capable of being actuated so as to engage and disengage wall sections or panels being moved between said primary and said storage tracks. When such an operative wall structure is employed to move a wall section or panel on to the primary track from the storage tracks the panel to be moved is engaged by the holders and then these holders are moved through the movement of the positioning structure so as to place the section or panel being moved on to the switches. The holders are then disengaged from the panel or section and the switches are manipulated so as to allow the panel to be moved along the primary track. In storing panels the reverse of this series of operations is employed.
