These sections (2, 3) are constructed so as to allow continuous or almost continuou (e.g. by toothed racks) adjustment of the base beams (4) supporting the panes, and also of the locking devices. Intermediate supporting beams can also be fitted in the frame. The frame can be collapsible and stackable, and the locking devices and intermediate supporting beams can be lowered to the bottom in closed guides, being also adjustable for height.
