Linear structural member having a drawn section and having weight-reducing slots

Claim 1

A linear structural member for the formation of reticulated structures intended to bear lighting means comprising: a single continuous section of enhanced area (1,203), two mutually spaced longitudinal expanded parts (1,3,201,219) with connecting means therebetween comprising a continuous linear web-like baffle (5,209), said continuous section comprising contiguous abutting segments connected in end-toend relationship by splice plates (7) connected to said baffles (5,209), said baffles (5,209) having cut-out weight-reducing slots (5A,229), an arcuate zone formed by connecting parts (8,205,207) which terminates at said longitudinal expanded parts (3,213,221), said longitudinal expanded parts designed as a rail (3,219) comprising two cylindrical shell portions connected by a diaphragm to form a duct between said arcuate portion and said diaphragm (223), said rail (3) of said expanded parts being designed to support light apparatuses therealong, said slots (5A,229) of said baffle being characterized by ribs along said continuous section, said continuous baffle (5,209) being of sufficient width to strengthen said structural member.
