Abstract
A folding sawhorse created by two pivotally connected frames containing a plurality of stress bearing structures on their inner surfaces forms a 60 degree angle when locked in place by a locking shelf. The frame components include two parallel vertical members separated at a distance by an upper horizontal brace and parallel lower horizontal brace. A U-shaped load bearing support is connected to the upper surface of the upper horizontal braces and provides four surfaces across which a load may be distributed when the folding sawhorse is in use. The trapezoidal locking shelf is pivotally connected to the lower horizontal braces and contains a central hinge, allowing the shelf to fold when the sawhorse is collapsed along its central vertical hinge.
Claims20
A folding sawhorse apparatus comprising:
- two rectangular frame components, wherein said rectangular frame components have a smooth outer surface and an inner surface containing at least one stress bearing structure, each of said frame components comprised of
- a first vertical member and a second vertical member, each of said vertical members having an upper section and a lower section terminating in a stabilizing surface, wherein said first and second vertical members are parallel,
- an upper horizontal brace connecting said first vertical member and said second vertical member at said upper sections,
- a lower horizontal brace parallel with said upper horizontal brace and connecting said first vertical member and said second vertical member at said lower sections, and
- a U-shaped load bearing support connected to an upper surface of said upper horizontal brace,
- wherein said first vertical member, said second vertical member, said upper horizontal brace and said lower horizontal brace define a rectangular central aperture, and
- wherein one of said two frame components contains a plurality of looped members along one of its vertical members and the other of said two frame components contains a second plurality of looped members along the one of its vertical members;
- a locking shelf comprised of
- a first side pivotally connected to said lower horizontal brace of one of said frame components,
- a second side pivotally connected to said lower horizontal brace of the other of said frame components,
- a central hinge pivotally connecting said first side and said second side;
- and
- a tubular member passing through said plurality and said second plurality of looped members and connecting said frame components in a V-shape with said inner surfaces facing each other when said folding sawhorse is in a locked position,
- wherein said frame components pivot inwardly about said tubular member to bring said inner surfaces in physical contact with each other.
