Abstract:
1. A swing joint for use in a scaffold system, said swing joint comprising: a swing head assembly, said swing head assembly comprising: a swing head, said swing head comprising opposed upper and lower extensions, each extension being of a generally rectangular prism shape and of substantially the same size as the other extension, each extension comprising a flat outer surface and a flat inner surface opposite the outer surface, and arranged such that the inner surface of the upper extension is parallel to and faces the inner surface of the lower extension; wherein each extension further comprises a front end and a rear end opposite the front end, and a gap is formed between the inner surfaces of each extension proximate the front ends thereof, each of the respective front ends including a substantially curved surface, and wherein the respective rear ends of each extension are connected at their respective inner surfaces to a connecting member, said connecting member being sized to be received by a horizontal member; wherein said upper extension further includes a upper through-bore extending from its outer surface to its inner surface proximate its front end, and said lower extension comprises a lower through-bore extending from its outer surface to its inner surface proximate its front end, said upper through-bore and said lower through-bore having substantially the same inner diameter and being substantially axially aligned with each other; and a cylindrical pin, said pin having an outer diameter corresponding to said upper through-bore and said lower through bore; and a rosette, said rosette comprising an annular disk with a central aperture extending therethrough, said central aperture sized to receive a vertical tubular member, said rosette further comprising a plurality of circumferentially arranged cut-outs extending therethrough, wherein said cut-outs are located radially between said central aperture and an outer circumference of said rosette; wherein said cut-outs are defined by a pair of concentric inner and outer arcuate edges, each pair of said inner and outer arcuate edges being joined together and spaced apart by a pair of radially extending edges, wherein said inner arcuate edges each comprise a first arc-shaped notch proximate a center thereof, said first arc-shaped notches extending inwardly towards said central aperture, and wherein said outer arcuate edges each comprise a second arc-shaped notch proximate a center thereof, said second arc-shaped notches extending outwardly towards said outer circumference of said rosette, such that the first and second arc-shaped notches of each cut-out define a circular aperture, said circular aperture having a diameter corresponding to the inner diameters of the upper and lower through-bores and with the outer diameter of said pin; wherein, in an assembled state, said rosette is received within said gap between the upper and lower extensions so that the upper and lower through-bores are axially aligned with a respective circular aperture of one of said plurality of cut-outs, and said pin is inserted through said upper and lower-through bores and through said circular aperture.
