Patent ID: 8162273

Claim:
An adjustable support device for a structure, the device comprising: an arcuate support bar terminating feet configured to engage with a ground surface; two spaced apart locking mechanisms pivotally connected to the structure and connecting the structure to the arcuate support bar, each locking mechanism including two spaced apart brackets positioned on opposite sides of the arcuate support bar so as to prevent angular movement of the support bar, a stop member and spaced apart upper and lower engagement rods extending between the brackets such that the arcuate support bar extends between the engagement rods; wherein the locking mechanisms are pivotally moveable between a first position, in which the stop member prevents further pivotal movement in one direction such that the engagement rods are positioned so as to allow the arcuate support bar to slide freely over the engagement rods, and a second position, when weight is applied to the locking mechanisms, in which the engagement rods lock against the arcuate support bar so as to prevent sliding movement therethrough so as to support the structure in a required orientation; and wherein the stop member is a rod extending between the brackets.
