Device for the assembly and disassembly of metal profiles provided with longitudinal surface grooves, said device comprising: a metal support (1) that can be inserted into the ends of the grooves of the profiles to be joined; a chassis (2) supported on each end of said metal support (1), whereon a lever (4) provided with a projection (9) and a coaxial cam (8) pivots (5); and a resilient body (3) inserted between the support (1) and the chassis (2). When the lever (4) is rotated into the represented closing position thereof, the protrusion (9) penetrates said resilient body (3), expanding it transversally against the side walls of the respective groove, and the cam (8) simultaneously compresses the resilient body (3), expanding the device in a direction which is orthogonal to the previous direction. The device allows a rapid, manual and toolless assembly and disassembly of the profiles, aligned or at an angle, in order to form frames such as those used in supports for displaying graphics. |
