<p>1. Device for stabilising and distributing pressure for a frame comprising grooves in the longitudinal members (25) and cross members (26) of the frame, and fixing elements, characterised in that the longitudinal members and the cross members of the frame comprise a first groove (20) formed as a prolongation of the internal border (19) in the plane of the frame and a second groove (21) formed in their rear wall perpendicularly to the plane of the frame, in that the said longitudinal members and cross members are fitted into the upright sleeves (6) or angled sleeves (11) of which the internal wall 7 comprises a bent-over edge entering into the said first groove (20) and of which the external wall (9) enters into the said second groove (21), in that the internal wall (7) of the said sleeves comprises a dove-tailed recess (10) and in that the fixing elements are composed of a removable resilient pressure blade (1) bent at an acute angle comprising an elongated arm (3) and a short arm (2) provided with profiled edges forming ridges (4, 5), the short arm (2) being intended to fit itself into the dove-tailed recess (10) of the sleeves.</p> |
