Abstract

A vertically adjustable armrest includes a tubular support constructed for attachment to a chair, an armrest assembly telescopingly positioned in the tubular support, the armrest assembly including a sleeve and a post, the sleeve including an opening adapted to receive an operative member on one side, and the post including positional detents extending down the length of a first vertical surface. The height adjustment mechanism is slidably received in the armrest assembly and includes an actuator rod having an angled ramp, an inclined surface, and a pair of angled surfaces, a locking member having teeth which are biased to selectively mate with the post detents, an inclined surface, and at least one pair of lateral followers. The actuator rod operatively engages the locking member with the inclined wedge mateably engaged with the inclined surface and the angled surfaces slideably engaged with the lateral followers.
