Boom arm for positioning an auxiliary electrical device

A boom arm assembly for positioning an auxiliary electrical device relative to a fixed anchoring portion, the auxiliary electrical device coupled with a flexible elongate supply link, the boom arm assembly comprising:

• an anchoring portion configured to attach to an anchoring surface;
• a mounting portion configured to attach to the auxiliary electrical device;
• a telescoping link including an elongate outer member and an elongate inner member, wherein:
• the outer member has an internal through bore and a first distal end, the first distal defining a ball joint which is connected to one of the anchoring portion or the mounting portion, the outer member including an anti-rotation member;
• and
• the inner member has an internal through bore and a second distal end, the second distal end defining a ball joint connected to the other of the anchoring portion and the mounting portion, the inner member being slidably positioned within the internal through bore of the outer member in a telescoping manner, the internal through bore of the inner member and the internal through bore of the outer member aligning with each other to allow passage of the flexible elongate supply link from the anchoring portion to the mounting portion, the inner member including a longitudinally extending anti-rotation groove, the anti-rotation member removably engaging the longitudinally extending anti-rotation groove;
• and
• a locking mechanism being connected with and configured for locking relative movement between the inner member and the outer member.
