Abstract
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.
Claims16
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 can be changed by said lifting.

A truss hinge, comprising:
- a first hinging part, having a first connection which connects to a first truss;
- a second hinging part, hinged relative to said first hinging part, and having a second connection which connects to a second truss,
- a zero holding surface on said first hinging part and a zero holding surface on said second hinging part, wherein when said zero holding surfaces are connected to one another, said first and second hinging parts are held at 0° angle relative to one another,
- and a plurality of other surfaces which each define a specified maximum amount of angle movement between said first truss and said second truss more than 0°, and where a connection between first and second surfaces for a specified angle allow movement between said first truss in said second truss by an angular amount up to said specified angle.

A method of operating a truss hinge, comprising:
- connecting a first hinging part to a first truss;
- connecting a second hinging part, hinged relative to said first hinging part, to a second truss,
- sliding between said first and second trusses on said hinging parts using at least one continuous slot which defines different angles including a first hinging slot which is connected to define a first set of angles including a first angle between said first hinging part and said second hinging part and said second hinging part includes a second hinging surface that is connected to define a second angle between said first hinging part and said second hinging part, and a connection between said first hinging slot and second hinging surface that limits an angle between said first and second trusses at different maximum angles relative to one another,
- moving said first truss and said second trusses between said different angles along at least one of said first hinging slot and said second hinging surface, and constraining a maximum angle by connecting between said first and second hinging parts, said maximum angle limiting the angle between said first and second trusses to an amount of said maximum angle, but allowing said trusses to be held at smaller angles closer to 0° than said maximum angle and at all other angles between said smaller angles up to said maximum angle.
