Abstract

A height adjustable pylon and supporting frame assembly is provided. The frame includes two frame members meeting at a corner with the frame members being generally co-planar and the pylon being urged into the corner so as to extend at generally right angles to a plane including the two frame members. A fastener assembly has two end portions each anchored relative its associated frame member so as to extend transversely to it. The fastener assembly includes an intermediate saddle portion engaging a surface of the pylon that is directed outwardly relative to the corner with the pylon being urged into the corner when the fastener assembly is tightened to engage the pylon and lock it axially relative to the frame members in a selected position. Preferably, the frame members each form two upper and two lower frame members of two trusses. Lower ends of the pylons may support the assembly.

First claim

The invention claimed is:

1. A pylon and supporting frame assembly comprising:
two frame members meeting at a corner with the two frame members being generally co-planar and the pylon extending at generally right angles to a plane including the two frame members and the two frame members have flattened and perforated overlapping ends that are bolted or riveted together, wherein a surface of the two frame members engaged by the pylon is pre-formed to provide a contact surface conforming to an outer surface of the pylon, and
at least one fastener assembly having two end portions each of which is anchored relative to its associated frame member so as to extend transversely relative to the associated frame member, and
the at least one fastener assembly further comprises an intermediate saddle portion engaging a surface of the pylon that is directed outwardly relative to the corner and each of the end portions of the at least one fastener assembly pass through the associated frame member,
wherein a connecting position of the pylon relative to the plane of the two frame members is vertically adjustable and the at least one fastener assembly engages the pylon and locks it axially relative to the two frame members in a selected vertical position.

2. The pylon and supporting frame assembly as claimed in claim 1 , wherein the at least one fastener assembly is a single elongate fastener and the intermediate saddle portion is configured to closely follow an outer surface of the pylon.

3. The pylon and supporting frame assembly as claimed in claim 1 , wherein the two frame members meet each other at the corner at an acute angle of about 60°.

4. The pylon and supporting frame assembly as claimed in claim 1 , wherein the two frame members are tubular frame members made of a deformable metal that is configured to provide contact surfaces.

5. The pylon and supporting frame assembly as claimed in claim 1 , comprising an upper two frame members and a lower two frame members, wherein each of the two frame members is part of one of two trusses with each truss having one or more inclined brace members extending between the upper straight frame member and lower straight frame member of each truss.

6. The pylon and supporting frame assembly as claimed in claim 5 , wherein the inclined brace members are selected from a group consisting of tubular section, angle section, channel section, and flat bar with flattened ends and a flattened central region that are perforated to accommodate bolts, rivets or other fasteners passing through them.
