Adjustable support structure

An adjustable support device, the device comprising:

• a frame for attachment to a structure to be levelled;
• an arcuate support bar terminating in feet configured to engage with a ground surface;
• two spaced apart locking mechanisms connecting the frame to the arcuate support bar, each locking mechanism including two spaced apart brackets positioned on either side 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 members extending between the bracket whereby the arcuate support bar extends between the engagement members;
• wherein the locking mechanisms are pivotally connected to the frame and pivotally moveable between a first position, in which the stop member prevents further pivotal movement in one direction such that the engagement members are positioned so as to allow the arcuate support bar to slide freely over the engagement members to locate the feet in engagement with the ground surface, and a second position, when weight is applied to the frame, in which the engagement members lock against the arcuate support bar so as to prevent sliding movement therethrough so as to support the structure in a levelled orientation;
• and
• wherein, in the first position, the pivotal connection of the locking mechanisms to the frame is above the horizontal level of the lower engagement member and, in the second position, the pivotal connection is substantially horizontally aligned with or below the lower engagement member.

A wheelbarrow, comprising:

• a chassis including a front wheel supporting a barrow;
• an arcuate support bar terminating in feet configured to engage with a ground surface;
• two spaced apart locking mechanisms connecting the frame or barrow to the arcuate support bar, each locking mechanism including upper and lower engagement members on upper and lower sides of the arcuate support bar, whereby the arcuate support bar extends between the engagement members;
• wherein the locking mechanisms are pivotally mounted and pivotally moveable between a first position, such that the engagement members are positioned so as to allow the arcuate support bar to slide freely over the engagement members, and a second position, when weight is applied to locking mechanisms through their connection to the frame or barrow, in which the engagement members lock against the arcuate support bar so as to prevent sliding movement therethrough so as to support the wheelbarrow in a levelled or a tilted orientation.
