Patent ID: 7410140

Claim:
A hanger assembly comprising: a) a truss having a first angle iron and a second angle iron, the first angle iron having an upper surface, a lower surface, an inner surface, and an outer surface, the second angle iron having an upper surface, a lower surface, an inner surface, and an outer surface, the truss having webbing connected to the inner surface of the first angle iron and the inner surface of the second angle iron and having a gap between the inner surface of the first angle iron and the inner surface of the second angle iron the gap having a gap dimension, the truss being configured so that the upper surface of the first angle iron has the highest elevation of any surface of the first angle iron and the upper surface of the second angle iron has the highest elevation of any surface of the second angle iron, the truss being configured so that the lower surface of the first angle iron has the lowest elevation of any surface of the first angle iron and the lower surface of the second angle iron has the lowest elevation of any surface of the second angle iron; b) a first member, a portion of which is operable to pass completely through the gap between the inner surface of the first angle iron and the inner surface of the second angle iron and contacting the upper surface of at least one of the first angle iron or the second angle iron and contacting the outer surface of at least one of the first angle iron or the second angle iron, the first member having a first dimension that is less than the gap dimension and a second dimension greater than the gap dimension; and c) a second member coupled to the first member, the second member contacting the lower surface of at least one of the first angle iron or the second angle iron, wherein the second member is coupled to the first member when the portion of the first member is positioned with the first dimension parallel to the gap and is passed through the gap between the angle irons and the first member is rotated so that the first dimension is non-parallel to the gap such that the first member is supported from the upper surface of the first angle iron and the upper surface of the second angle iron, and is held in place by contact of the second member with the lower surface of the first or second angle iron.
