ABSTRACT:
This invention relates to a process and a device for an angular connection of the end of a tube with one (or more) sheet metal element(s), quickly and reliably.
The forward portion of a tubular shape (1) is contracted by force-fitting in a ring (2) whose outside dimensions are approximately equal to those of the opening (4) and the inside dimensions, less than the initial outside dimensions of the tubular shape, and whose rear end (6) is flush with the rear face (7) of the sheet metal (3), this ring (2) being compressed on the thickness of the sheet metal (3) between the tubular shape (1) and the opening (4) in the sheet metal, while the end (10) of the tubular shape is flanged outward in a corolla on the rear face (7) of the sheet metal element.
This process can be used in particular to attach rungs to side rails of a ladder or rods to rails of guard railings and also for making scaffolding or tube exchangers.
