Patent ID: 7121756

Claim:
A system for mounting audio devices comprising a telescoping post mechanism including an inner post having one or more anti-rotation ribs, a ball-joint socket coupled to a first end of the inner post, the ball-joint socket to couple to an audio device, an outer sleeve having a receiving first end and a mounting second end, the outer sleeve defining an inner passage to receive the inner post from the receiving first end, the outer sleeve including one or more slots for receiving the anti-rotation ribs, and a first lock ring sized to fit around the circumference of the first end of outer sleeve, the first lock ring including one or more protruding tensioning ribs that rotationally act on tensioning ramps on the first end of the outer sleeve to tighten the first end of the outer sleeve around the inner post and secure the inner post at a desired position; and an angling mechanism including a rotating ball coupler sized to fit within the ball-joint socket, the rotating ball coupler capable of rotating within the ball-joint socket, an audio device housing coupled to the rotating ball coupler, a second lock ring sized to fit around a circumference of the ball-joint socket and tighten the ball-joint socket around the rotating ball, and a reverse angle retention system between an inner circumference of the second lock ring and the outer circumference of the ball-joint socket to prevent the second lock ring from slipping off, wherein in the reverse angle retention system a lower inner diameter of the second ring lock is smaller than an upper outer diameter of the ball-joint socket and an upper inner diameter of the second ring lock is larger than a lower outer diameter of the ball-joint socket.
