<p>Closing units in in buildings or vehicles offering accommodation are at least temporarily insertable, removable, and sealable, and pref. in the form of auxiliary, or ventilating windows. To hold the assembly of such pane-shaped units (1) in position, use is made of a number of hollow bars (6,7) supporting a bounding plane for them, adjustable according to their overall length, set in rows at mutual intervals and force-locked onto rigid components (10) in the overall assembly. Bars can be telescopic, and held under spring action. Permanent magnets can be incorporated.</p> |
