Claim 13:
14. A frame comprising:
a mounting assembly comprising a first mounting member, a second mounting member and a third mounting member, wherein
each of the first and second mounting members comprises a first bar and a second bar;
proximal end portions of the first and second bars of the first mounting member are connected to or formed with each other;
proximal end portions of the first and second bars of the second mounting member are connected to or formed with each other; and
the third mounting member having an end portion coupled with the proximal end portions of the first bars of the first and second mounting members and another end portion coupled with the proximal end portions of the second bars of the first and second mounting members;

a first leg assembly and a second leg assembly, wherein the first leg assembly is coupled with distal end portions of the first bars of the first and second mounting members and rotatable with respect to the first bars, and the second leg assembly is coupled with distal end portions of the second bars of the first and second mounting members and rotatable with respect to the second bars; and
a first supporting assembly and a second supporting assembly configured to control rotation of the first and second leg assemblies, wherein each of the first and second assemblies comprises:
a first supporting member having an end portion pivotally coupled with the third mounting member;
a slider coupled with the first supporting member and selectively movable along the first supporting member; and
one or more second supporting members, each having an end portion coupled with the slider and another end portion pivotally coupled with the first or second leg assembly;

wherein the proximal end portions of the first and second bars of the first mounting member are pivotally coupled with each other by a first pivoting mechanism and the proximal end portions of the first and second bars of the second mounting member are pivotally coupled with each other by a second pivoting mechanism, wherein the first or second pivoting mechanism comprises:
a first coupling piece fixed at the proximal end of the first bar of the first or second mounting member and comprising a first slot elongated in a first direction;
a second coupling piece fixed at the proximal end of the second bar of the first or second mounting member and comprising a second slot, wherein the second slot has a closed bottom and an open top, and wherein the second slot has a length in the first direction that is shorter than the first slot of the first coupling piece in the first direction;
a third coupling piece comprising a third slot having a closed bottom and a closed top, wherein the third slot is elongated in the first direction;
a first rod disposed, cross-sectional-wise, in the third slot of the third coupling piece and movable along the third slot of the third coupling piece, wherein the first and second coupling pieces are pivotally coupled with each other by the first rod; and
a second rod integrally formed or coupled with a top portion of the third coupling piece, wherein the second rod is disposed, cross-sectional-wise, in the first slot of the first coupling piece and movable along the first slot of the first coupling piece;
wherein when the first and second coupling pieces are aligned with each other and the open top of the second slot of the second coupling piece faces downwardly, the third coupling piece together with the second rod moves by gravity to a first position where the second rod is disposed outside of the second slot of the second coupling piece, thereby allowing the first and second coupling pieces to rotate with respect to each other around the first rod; and
wherein when the first and second coupling pieces are aligned with each other and the open top of the second slot of the second coupling piece faces upwardly, the third coupling piece together with the second rod moves by gravity to a second position where the second rod is disposed in the second slot of the second coupling piece, thereby restricting the first and second coupling pieces from rotating with respect to each other around the first rod.
