Abstract:
1. A structural framework comprising: (a) a first support beam, the first beam having ends forming a C-channel shape with an interior, the ends having first and second inwardly facing flanges, and the interior having a first longitudinal centerline; (b) a first support bracket connectable to the first support beam, the first support bracket comprising: wherein the first support bracket has locked and unlocked states relative to the first support beam, and the first support bracket changes from an unlocked state to a locked state relative to the first support beam by rotation in a first rotational direction about an axis which is generally parallel to the first longitudinal axis and creating a rotational locking force between the first support bracket and the first support beam which increases as the amount of weight supported by the first support bracket is increased, and the first support bracket changes from a locked state to an unlocked state relative to the first support beam by rotation in a second rotational direction about the axis which is generally parallel to the first longitudinal axis, but opposite of that of the first rotational direction of the first support bracket; and (iv) a first clamping section releasably connectable to the first support bracket and when connected to the first support bracket maintaining the first support bracket in the locked state relative to the first support beam by squeezing the first support beam between the first support bracket and the first clamping section.
