Abstract
Official abstract text for this publication.
A truss hinge that includes a number of different labeled parts, where connections between the two different parts can constrain the truss to different angles.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of raising a two part truss into a position where the two parts of the truss are at non-right angles with one another, comprising: locating the two part truss on a flat surface where the two parts of the truss lay flat relative to one another; where the two part truss has said first and second truss parts that are hinged relative to one another, hinged by a hinging part that has a holding part that constrains a maximum amount of motion between said first and second truss parts, attaching a lifting mechanism to an area of the two part truss between said first and second truss parts; lifting the area, where said lifting causes said two parts to move up and to change an angle relative to one another, where said angle is constrained by surfaces of said hinging part to limit an amount by which the angle is changed by said lifting, wherein the truss is transported with said hinging part constraining the first and second truss parts at 0° angles relative to one another, and further comprising moving the holding part to another holding surface which allows the first and second truss to pivot relative to one another to a desired angle greater than 0. 2. The method as in claim 1 , further comprising changing the holding part to change the angle that is constrained by the hinging part. 3. The method as in claim 1 , wherein there are a number of different stop surfaces on the holding part, defining a number of different angles.
