Abstract
Abstract A structural truss composed of spaced rails interconnected by a series of struts swingably coupled at their ends. Track members on the rails receive the ends of the struts which are slid into place between the rails. Thereafter, the struts are crimped in place upon the rail members to form a load supporting structural member. In a second embodiment, rivets are slipped into the track members, the struts are slipped upon the rivets and the ends of the struts and the rivets are deformed to form the structural truss.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
A structural truss comprising at least two spaced elongated-shaped rails consisting of a horizontal flanged portion and an elongated track having a substantially "C" shaped cross sectional shape normally disposed on the flanged portion, a plurality of flat headed rivets slidably received within the "C" shaped track, said rivets having shank portions extending through the apertures of the "C" shape and outwardly of said track, a plurality of struts comprising elongated bar shaped members apertured adjacent each end thereof and disposed as a series between the rails with their adjacent apertured ends slipped over one of said rivet shanks and freely and rotatably secured thereto and at least one deformed portion on the tracks adjacent each of the ends of the links to prevent longitudinal movement of the rivets with respect to the rails.
Claim 2
Dependent Claim
134 words
A structural truss comprising at least two spaced elongated-shaped rails consisting of a horizontal flanged portion and an elongated track having a substantially "C" shaped cross sectional shape normally disposed on the flanged portion, a plurality of flat headed rivets slidably received within the "C" shaped track, said rivets having shank portions extending through the apertures of the "C" shape and outwardly of said track, a plurality of struts comprising elongated bar shaped members apertured adjacent each end thereof and disposed as a series between the rails with their adjacent apertured ends slipped over one of said rivet shanks and freely and rotatably secured thereto and at least one deformed portion on the tracks adjacent each of the ends of the links to prevent longitudinal movement of the rivets with respect to the rails.
Claim 3
Dependent Claim
33 words
A truss according to claim 1 in which the rails are disposed in a non-parallel orientation, the struts are of equal length and are angularly disposed to hold the rails in spaced relationship.
Claim 4
Dependent Claim
23 words
A truss according to claim 1 in which the struts are laterally offset for a portion of their length intermediate the ends thereof.
Claim 5
Dependent Claim
22 words
A truss according to claim 1 in which the deformed portion of the track is disposed on each side of the rivets.
Claim 6
Dependent Claim
22 words
A truss according to claim 1 in which the tracks are deformed beneath the strut ends and around each of the rivets.
Claim 7
Dependent Claim
23 words
A truss according to claim 5 in which at least one of the strut ends are also deformed adjacent the rivet shank portion.
