Claim:
A connector assembly for pivotally supporting an arm, the arm including an opening that extends therethrough, the connector assembly comprising: a first structural support plate and a second structural support plate configured to pivotally receive the arm therebetween, the first structural support plate having a first opening and the second structural support plate having a second opening; a collar fixed at the first structural support plate and having an inner surface defining a bore in concentric relation to the first opening in the first structural support plate, the collar further including a collar pin opening aligned perpendicular to the bore; a connector pin having an outer surface and pivotally coupling the arm between the first and second structural support plates, the connector pin received through the bore of the collar and the first and second openings in the first and second structural support plates, respectively, the connector pin including a first end having an exterior threaded portion and a second end being free of threads and having a lock pin opening extending therethrough; a connector pin nut having threaded interior configured to receive the exterior threaded portion of the connector pin; a lock pin received through the lock pin opening and the collar pin opening, wherein the lock pin includes a first end with a head portion opposite a second end with an exterior threaded portion; and a lock pin nut having a threaded interior that receives the threaded exterior portion of the lock pin to secure the lock pin in the connector pin opening and the collar pin opening; wherein: the lock pin prevents rotation of the connector pin; rotation of the connector pin nut on the connector pin selectively urges the first and second structural support plates towards each other; the arm is laterally supported between the first and second structural support plates; and the outer surface of the connector pin engaging the inner surface of the collar.
