Joint and foldable structures employing the same
First Claim
1. A grill and support structure, comprising:
- first and second foldable support members each made up of a plurality of pivotably linked brackets each having a front end and a back end, said front end having a normally extending stop protrusion projecting from a side of said respective bracket and having a stop surface, said front end defining a front pivot point, said back end having an arcuate outer periphery and defining a back pivot point and at least a portion of a first edge surface, said first edge surface including an assembly notch thereon between said front and back end, said front end being joined to said back end of an adjacent bracket at said pivot points such that said brackets pivot relative to each other between a stowed position in which all of said brackets are adjacent to, each other in a parallel, aligned orientation, an extended position in which some of said brackets extend linearly relative to each other and said stop surface of one bracket engages said assembly notch of said first edge surface of an adjacent bracket proximate said back end thereof, and an angled position in which other of said brackets extend at an obtuse angle with respect to each other and said stop surface of one bracket engages said assembly notch of said first edge surface of an adjacent bracket proximate said back end thereof;
said first foldable support member being configured such that some of brackets in a middle section thereof being in the extended position and two of the brackets proximate opposed end sections of the first foldable support member are in the angled position;
said second foldable support member being configured such that some of brackets in a middle section thereof being in the extended position and two of the brackets proximate opposed end sections of the second foldable support member are in the angled position;
said first and second support members intersecting one another in their respective middle section at complementary assembly notches to form a support structure with opposed terminal ends of each first and second support member engaging a support surface to position the brackets in the middle section above the support surface;
a grate for use as a grill positioned on said first and second support members, at least one of said brackets further including corresponding grate notches for accommodating and supporting said grate.

Abstract
A folding joint mechanism for stackably collapsing elongated structural sections includes a plurality of substantially identical brackets pivotably interconnected and rotatable between an extended and a stowed configuration. In the extended configuration, the brackets abut each other against stop protrusions on the top outside surface of each bracket forming foldable extensions that are able to support significant weight by distributing the top. side force. In the stowed configuration, the brackets are compacted to a substantially stacked disposition whereby the brackets are aligned and directly adjacent to one another. The joint and bracket assemblies may be employed in elongated sections of various structures in which compactability may be advantageous for shipping, storage, and user transportation.
