An adjustable support device (10) for a structure, including an arcuate support bar (26) terminating in feet (28) for engagement with a ground surface. Two spaced apart locking mechanisms (30) are pivotally connected to the structure. The arcuate support bar (26) extends between engagement rods (36a, 36b) of the locking mechanisms (30). The locking mechanisms (30) are pivotally moveable between a first position, in which a stop member (38) prevents further pivotal movement in one direction such that the engagement rods (36a, 36b) are positioned to allow the arcuate support bar (26) to slide freely over the engagement rods (36a, 36b), and a second position, when weight is applied to the locking mechanisms (30). In the second position, the engagement rods (36a, 36b) lock against the arcuate support bar (26) to prevent sliding movement there through for supporting the structure in a required orientation. |
