Abstract:
1. A truss hinge, comprising: a first hinging part, having a first connection which connects to a first truss; a second hinging part, hinged and movable relative to said first hinging part, the second hinging part having a second connection which connects to a second truss, wherein the first hinging part and the second hinging part are removably attached to a structure, wherein said first hinging part includes a plurality of continuous slots which define 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 pivotable connection between said first hinging slot and said second hinging surface that limits angular movement between said first and second trusses at different maximum angles relative to one another, said first hinging slot and said second hinging surface enabling moving said first truss and said second truss between said different angles along one of said first hinging slot and said second hinging surface, and constraining the maximum angle by connecting between said first and second hinging parts, said maximum angle limiting the angular movement between said first and second trusses to an amount of said maximum angle, but allowing said first and second 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.
