ABSTRACT:
An adjustable position mechanism is provided for selectively varying the position of a first member relative to a second member. This adjustable position mechanism includes a support, and an elongated arm projecting from the support and having a plurality of locking elements in a linearly spaced array for defining a plurality of increments of position and a guide. An actuator has cooperating locking elements of complementary form to the locking elements of the arm, a moveable element for selectively moving the cooperating locking elements into and out of engagement with the locking elements of the arm, and a cooperating guide engageable with the guide of the arm for guiding reciprocal longitudinal movement of the actuator relative to the arm. A housing is coupled with the first member and with the actuator for operatively coupling the first member to move reciprocally with the actuator relative to the arm.
