<p>A support framework for panels, doors and the like comprises profiled sections joined together at right angles by releasable fixing means. To permit quick and easy assembly, at least a first section (11) of the profiled sections has two longitudinal surfaces (11a, lib) joined together by a longitudinal connecting surface (11c) so as to form a step; coupling means (17) associated with at least a second section (12) of the profiled sections have stepped surfaces (17a, 17b, 17c) which can be juxtaposed with the stepped surfaces (11a, 11b, 11c) of the first section (11), and the fixing means comprise means for restrained engagement (18, 19) between the coupling means (17) and the first section (11). <IMAGE></p> |
