Novelty: a folding system of aluminium profiles is disclosed. Constitution: the steady part (1) and two moving sections (2, 3) which can be deployed in height thanks to the tubular motor found inside the base (5) of the system, the transmission of the motion being achieved via the belt (4) and the sheave (6). Deployment mode: complete deployment is achieved by the moving part (3) which entrains the moving section (2) until the set of screws and wheels (7) attains the upper terminal position of this last. Purpose: to enclose spaces with glass panels, cement boards, sheet iron surfaces etc. |
