Patent ID: 8894316

Claim:
An adjustable joint for use with a microphone, comprising: a ball; a stem that extends from the ball; and a ball housing into which the ball is located, wherein an edge of the ball housing defines a slot that has a length that extends along a portion of a front side of the ball housing and along an entire end of the ball housing and along a portion of a back side of the ball housing, wherein the slot is wider at a location at the front side of the ball housing and at a location at the back side of the ball housing than at a location at the end of the ball housing, wherein the stem is located in the slot and is capable of engaging the ball housing so as to limit movement of the ball and the stem with respect to the ball housing, wherein the edge of the ball housing from the front side of the ball housing to the back side of the ball housing is continuous so as to be continuous at the end of the ball housing along an entire length of the slot at the end of the ball housing on opposite sides of the slot at the end of the ball housing; a cup member inside the housing and below the ball, wherein the cup member engages the ball; a plunger engaged through a side of the housing below the cup member, wherein an end of the plunger projects into a chamber formed in the housing, the chamber containing: a first rod that has a curved outer surface, wherein the first rod has a longitudinal axis about which the curved outer surface extends, wherein said longitudinal axis is substantially perpendicular to said plunger; a second rod that has a curved outer surface that engages the curved outer surface of the first rod; and, a third rod that has a curved outer surface that engages the curved outer surface of the first rod and wherein the first rod has a diameter greater than either of the second rod or the third rod; wherein the second and third rods rest against a bottom surface of the chamber and are positioned below the first rod; and wherein the plunger is capable of engaging the second rod so as to impart force onto the second rod to move it along the bottom surface of the chamber into the first rod such that the first rod is moved in a direction perpendicular to its longitudinal axis, wherein movement of the first rod causes the first rod to be urged against the cup member which in turn causes the cup member to be urged against the bait which in turn causes the ball to be urged against the ball housing so as to limit movement of the ball and the stem with respect to the ball housing.
