ABSTRACT:
First and second legs (4 and 5) of a collapsible tripod (1) are pivoted to a third leg (6) and interconnected by two interpivoted bracing links (15 and 16).
To swing the first and second legs (4 and 5) towards and away from the third leg (6), first and second tie members (24 and 25) extend, respectively, from the first and second legs (4 and 5) to an actuating member (18) which is movable longitudinally of the third leg (6).
To prevent relative movement between the legs (4, 5 and 6), when the tripod (1) is in its extended condition, a control link (32) extends from the pivotal interconnection between the two bracing links (15 and 16) and the actuating member (18) and locking means (21) are provided for releasably locking the actuating means (18) to the third leg (6).
