Abstract:
1. An articulating shower arm, comprising: an elbow portion adapted to fluidly communicate with a water supply and further comprising an insertion end having one or more elbow splines; an arm portion having a short portion defining a short axis and a long portion defining a long axis configured substantially perpendicular to each other and adapted to fluidly communicate with a shower head and further comprising a receiving end having one or more arm splines; means for selectively locking and pivoting the position of the arm portion relative to the elbow portion; an adjustment post having a first end operatively attached to an end of the elbow portion and a second end configured to receive the locking means; and a spring disposed between a surface of the elbow portion and a surface of the arm portion, the spring acting to bias the arm portion away from the elbow portion; wherein the long axis of the elbow portion and the long axis of the arm portion form an angle, the arm portion and the elbow portion form a continuous channel configured to fluidly connect the water supply with the shower head, the insertion end of the elbow portion is received within the channel in the short portion of the arm portion thereby pivotably coupling the arm portion with the elbow portion about the long axis of the elbow portion, the adjustment post extends within the channel in the elbow portion coaxially with a long axis of the elbow portion and through an exit opening in the arm portion, the one or more elbow splines are complementary to the one or more arm splines; the arm portion and the elbow portion are engaged by the interaction of the one or more elbow splines with the one or more arm splines when the insertion end of the elbow portion resides inside the receiving end of the arm portion, when the means for selectively locking is in a locked configuration, the interaction of the one or more elbow splines with the one or more arm splines causes the arm portion to be held substantially immovable relative to the elbow portion and causes the spring to be substantially immovably compressed between the surfaces of the elbow portion and the arm portion, and the interaction of the one or more elbow splines with the one or more arm splines in the locked configuration is due to a force applied by the means for selectively locking and pivoting that acts against a force applied by the spring.
