A leg assembly (12) for a tripod (10) comprises a first leg unit (13), a second leg unit (14) and a third leg unit (15). First leg unit (13) includes legs (13A and 13B). Second leg unit (14) includes legs (14A and 14B). Legs (14A and 14B) are laterally spaced from each other and held in fixed position by an upper cross member (17) and a lower cross member (18). Legs (13A and 13B) can slide through openings in upper cross member (17). Leg (15A) can slide through an opening in lower cross member (18). Upper cross member (17) includes a first fixing means for selectively locking and unlocking the first leg unit in position. The lower cross member (18) includes a second fixing means for selectively locking and unlocking the third leg unit in position. A first lever (23) is used to selectively actuate the first fixing means. A second lever (24) is position adjacent to first lever (23). Second lever (24) is connected via a connecting means such as torsion bar (25) to the second fixing means. First lever (23) and second lever (24) can be actuated independently to enable either of the first or second fixing means to be actuated. Alternatively, due to the close proximity of first lever (23) and second lever (24), both levers can be actuated simultaneously to effect actuation of the first fixing means and the second fixing means.
