Abstract
An arm assembly includes an outer stem (52) and an inner stem (50) slidable in the outer stem and including a number of recesses (107) along its length. A biased locking device (117) engages one or more of the recesses (107) to lock the position of the inner stem (50) relative to the outer stem (52). A release member (103) operably connected to an actuator (101) has a number of recesses (110) and raised surfaces (112), the release member (103) slidable relative to the inner stem (50) between a first position in which recess(es) (110) in the release member is/are aligned with recess(es) (107) of the inner stem and the locking device (117) engages recess(es) in the stem (50) to inhibit movement thereof relative to the outer stem, and a second position in which raised surface(s) (112) of the release member align(s) with recess(es) (107) of the stem (50) to disengage the locking device from the recess(es) of the stem.
