Abstract From the Canadian patent

An assembly and method for mounting linear structures in locked longitudinal alignment which includes, retainer bars joinable to a bracket for mounting linear structures and a pin assembly having wedge pins protruding outwardly from a base wherein the wedge pins engage opposing apertures in a locked, spring-loaded interface tightened into alignment by a retainer screw. The locked interface between opposing edges of the wedge pin and the apertures impart strong resistance to displacement forces thereby providing, a system for joining and mounting permitting adjustment and alignment of independently suspended linear structures and subsequent tightening down of the linear structures.

Why it's free to use

  • Filed May 1, 1996 and granted July 9, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 1, 2016.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 1, 2018.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
