Patent ID: 8915041

Claim:
A device for adjusting angles between multiple trusses of a dual pipe truss that has two parallel cylindrical pipes, said device comprising: a first plate, having a connection part to a first truss, said connection part of said first plate connecting to both of first and second cylindrical and parallel pipes of the first truss, said first plate including a first slot extending along a length of the first plate; a second plate, movable relative to said first plate, said second plate also having a second connection part connecting to first and second cylindrical and parallel pipes of a second truss, said second plate including a second slot, extending along the length of the second plate; a hinging part that hinges said second plate relative to the first plate in a way that allows the second plate to move relative to the first plate while the first and second plates are each connected to said first and second pipes of said respective trusses and holds said first and second plates relative to one another, said hinging part including a locking plate that extends and holds between said first slot of said first plate and said second slot of said second plate, where said locking plate is loosened to allow said hinging part to hinge between said first plate and said second plate, and is tightened to hold said first plate to said second plate, said locking plate forming an angle setting part that holds said first plate relative to said second plate at any of a number of different relative locations between said first plate and said second plate; where each of said first plate and said second plate include angle markings thereon as text which indicates an numerical indication of an angle which will be formed between trusses that are connected to said first plate and said second plate when said locking plate is located adjacent said angle markings.
