Abstract:
1. A pole assembly comprising a base, an upper mast and a cladding, said base comprising a first tubular member of substantially constant cross section, and said upper mast comprising a second tubular member of substantially constant cross section smaller in cross section than said first tubular member, and in use to assemble said pole assembly a free end of said second tubular member is inserted within a free end of said first tubular member so that a portion of said first tubular member overlaps said second tubular member allowing for a plurality of fasteners to removably secure said second tubular member to said first tubular member, and said cladding surrounds said first tubular member and said fasteners, wherein a transition ring is disposed around a portion of said first and second tubular members and said cladding at said free end of said first tubular member, said transition ring having an internal downwardly facing surface, and a seal assembly is disposed within said transition ring to seal between the external surface of said second tubular member and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal; wherein said first tubular member comprises a plurality of first longitudinally extending channels that form corresponding longitudinal projections in its interior, and said second tubular member comprises a plurality of second longitudinally extending channels, and wherein said longitudinal projections project into said second longitudinally extending channels when said second tubular member is inserted into said first tubular member, and said transition ring has a plurality of spaced apart steps, each step projecting into one of said second longitudinally extending channels from the bottom of a recess in said transition ring that open to the top of said transition ring, said downwardly facing surface including the underside of said steps.
