Patent ID: 7516513

Claim:
An adjustable engagement glide installed on a tubular product end with a known outside surface shape that is substantially normal to the tubular product axis comprising: a. a single-piece main body, a bolt with a head portion and a threaded portion, a bushing, and a bushing deformation nut; b. the single-piece main body comprising a concavity with an outer surface, an inner surface, and a surface contact area, and an attachment extension with an inner surface arranged in the shape of the tubular product outside surface, an outer surface, a first end at the concavity surface contact area, and a second end with an opening arranged to contain the bushing and bushing deformation nut within the inner surface and within the attachment extension ends, and further arranged for insertion of the tubular product end inside the inner surface, wherein the inner surface of the attachment extension is arranged to contact the outside surface of the tubular product, an opening centrally arranged with the attachment extension first end and sized larger than the bolt threaded portion and smaller than the bolt head; c. the bushing with a first end and a second end, an outside surface, and a through-hole arranged between the first and second ends, the through-hole arranged such that the bolt threaded portion fits within the hole; d. the bushing deformation nut arranged with a threaded portion to threadedly engage the bolt threaded portion; e. the bolt arranged with the bolt head protruding from the main body attachment extension first end opening such that the bolt threaded portion extends centrally into the attachment extension wherein the bushing through-hole is around the bolt, forming an installation annulus between the attachment extension inner surface and the bushing outside surface; f. the bushing deformation nut further arranged in frictional engagement with the bushing second end such that turning the bolt head in one direction causes the nut to compressively engage the bushing and turning the bolt head in the opposite direction releases the compressive engagement of the bushing, wherein with the tubular product fully inserted into the installation annulus and the glide fully installed, the compressive engagement of the bushing on the tubular product is adjustable; and g. the concavity inner and outer surfaces arranged in a hollow concavity initiating from the attachment extension first end and beginning with a surface contact area, then curving toward the attachment extension second end, and terminating in a concavity end offset from the attachment extension containing the tubular product.
