ABSTRACT:
A boom stand is constructed from a base, extensible stand, pivotal boom support, and boom. The base has arcuately segmented massive anchors that form a perimeter. The arcuately segmented massive anchors are shaped and sized to fit within the perimeter of like bases, to decrease minimum distances between stands during storage or close use, while still providing stability. Over-center clamps provided on the extensible stand are extruded to include unitary cord guides, and are engaged with tube ends to prevent rotation or accidental removal. The pivotal boom support incorporates a disc and elastomeric pads to provide superior locking and vibration reduction, and utilizes in alternative embodiments perimeter and central over-center clamps which further enhance the operation.
