Supporting framework

A method of assembling a supporting framework, the supporting framework including a first frame having a first side tube and a second side tube connected by at least one transverse tube, a second frame having a third side tube and a fourth side tube, two first receiving fingers, and two second receiving fingers, the method comprising:

• i) mounting a diagonal cross brace onto to the second side tube by threading a first opening of a first strut of a diagonal cross brace onto a base portion of a first of the two first receiving fingers via a rigid bent end portion of the first of the two first receiving fingers;
• ii) mounting the diagonal cross brace onto to the third side tube by threading a first opening of a second strut of the diagonal cross brace onto a second base portion of a second of the two first receiving fingers via a second rigid bent end portion of the second of the two receiving fingers;
• iii) pivoting the diagonal cross brace so that:
• a) a second opening of the second strut is pushed over an end portion of a first of the two second receiving fingers and onto a base portion of the first of the two second receiving fingers, wherein the first of the two second receiving members is mounted to the second tube, and b) a second opening of the first strut is pushed over a second end portion of a second of the two second receiving fingers and onto a second base portion of the second of the two second receiving fingers, wherein the second of the two second receiving members is mounted to the third tube;
• iv) pivoting the end portion of the first of the two second receiving fingers so that the end portion of the first of the two second receiving fingers protrudes beyond a diameter of the second opening of the second strut and overhangs the second opening of the second strut and locking the end portion of the first of the two second receiving fingers via a detent mechanism;
• and
• v) pivoting the second end portion of the second of the two second receiving fingers so that so that the second end portion of the second of the two second receiving fingers protrudes beyond a diameter of the second opening of the first strut and overhangs the second opening of the first strut and locking the second end portion of the second of the two second receiving fingers via a second detent mechanism, thereby preventing unintentional release of the diagonal cross brace from the second and third tubes.
