A musical instrument bracket assembly is mounted on a top end of a post
and has a base, a pivot bracket, a pivot pin, a compression knob and a
standoff rod. The base has a tongue. The pivot bracket is mounted
pivotally on the tongue and has a standoff hole, two pivot wings, a gap
and a stationary compression fitting. The pivot wings extend down from
the standoff hole and are mounted pivotally on opposite sides of the
tongue. The stationary compression fitting is formed on one of the pivot
wings. The pivot pin extends through the pivot wings and the base. The
compression knob is attached to the pivot pin and has a rotatable
compression fitting corresponding to the stationary compression fitting.
When the compression knob is turned to an adjusting position, the
compression fittings release the pivot bracket and the standoff rod with
a single action.
