Abstract
Securement bracket including a base plate and a cylindrical body; the base plate (11) and the cylindrical body are of a single piece, the cylindrical body including two opposite walls called median wings (12, 13) in prolongation at 90° from the base plate (11) and two other opposite walls called flaps (16, 17) in prolongation at 90° from the median wings (12, 13), which have at least one opening in which is disposed a tongue (23) provided at the end of the flaps (16, 17). A process for production of such a bracket and cutout plate for the practice of the process are disclosed.

Process for the production of a securement bracket comprising, from a single piece, a base plate and a tubular body, characterized by the fact that it comprises the steps consisting in:
- cutting out a sheet steel blank such that it defines a central portion (11) of generally rectangular shape bordered by two lateral portions which comprise a so-called median wing (12, 13) bordered laterally by a flap (16, 17) itself bordered, on the central portion side (11), by a slot (16A, 17A);
- each flap (16, 17) being provided, on its free side perpendicular to the slot (16A, 17A), with at least one tongue (22, 23) adapted to penetrate into a rectangular opening (24, 25) on the other wing (13, 12);
- bending each flap (16, 17) about a bend line (18, 19) perpendicular to the slot (16A, 17A) so as to render it perpendicular to the adjacent wing (12, 13);
- bending each wing (12, 13) provided with its flap (16, 17) about a bend line (14, 15) parallel to the slot (16A, 17A) and disposed between the slot (16A, 17A) and the central portion (11), so as to render said wings (12, 13) perpendicular to the central portion (11), the tongue (22, 23) being disposed, at the end of bending, in said rectangular opening (24, 25).
Cutout blank for the production of a securement bracket, characterized in that it comprises a central portion (11) of generally rectangular shape flanked by two lateral portions which comprise a so-called median wing (12, 13) bordered laterally by a flap (16, 17) itself bordered, on the side of the central portion (11) by a slot (16A, 17A0, each flap (16, 17) being provided, on its free side perpendicular to the slot (16A, 17A) with at least one tongue (22, 23) adapted to penetrate into the rectangular opening (24, 25) of the other wing (13, 12).
Securement bracket, characterized in that it comprises a base plate of generally rectangular shape flanked by two lateral portions, in that each of the lateral portions comprises on the one hand a so-called median wing (12, 13) and on the other hand a flap (16, 17), in that each median wing (12, 13) extends perpendicular to the central portion (11) and is connected to this latter by a first bend line, in that each flap (16, 17) is bent about a bend line perpendicular to the first corresponding bend line of the wing (12, 13), in that each flap (16, 17) is provided with at least one tongue (22, 23) which penetrates within a rectangular opening (24, 25) in the other wing (13, 12), and in that the median wings (12, 13) and the flaps (16, 17) constitute a cylindrical body.
Securement bracket comprising a base plate and a cylindrical body, characterized by the fact that the base plate (11) and the cylindrical body are of a single piece, the cylindrical body comprising two opposite walls called median wings (12, 13) in prolongation at 90 degrees of the base plate (11) and two other opposite walls called flaps (16, 17) in prolongation at 90 degrees of the median wings (12, 13), which have at least one opening (24, 25) in which is disposed a tongue (22, 23) provided at the end of the flaps (16, 17).
