Abstract
A frame includes a mounting assembly having a plurality of mounting members connected to or integrally formed with each other. The frame also includes first and second leg assemblies pivotally connected with the mounting assembly at first and second sides of the mounting assembly, respectively. The first and second leg assemblies are foldable into an interior defined by the mounting assembly and, when folded, are substantially on the same plane as the mounting assembly. The frame further includes one or more supporting assemblies to help stabilize the first and second leg assemblies and support the mounting assembly when the frame is unfolded. Thus, the frame is compact when folded and stable when in use.

A foldable frame comprising:
- a mounting assembly comprising:
- a first mounting member;
- a second mounting member spaced apart from the first mounting member;
- and
- a connecting member disposed between the first and second mounting members, the connecting member having a first end portion connected to or integrally formed with the first mounting member and a second end portion connected to or integrally formed with the second mounting member;
- first and second leg assemblies, wherein
- the first leg assembly is pivotally connected with the mounting assembly at a first side of the mounting assembly;
- and
- the second leg assembly is pivotally connected with the mounting assembly at a second side of the mounting assembly;
- first and second supporting assemblies, wherein
- the first supporting assembly is pivotally connected with the first leg assembly and the connecting member of the mounting assembly and configured to control rotation of the first leg assembly with respect to the mounting assembly;
- and
- the second supporting assembly is pivotally connected with the second leg assembly and the connecting member of the mounting assembly and configured to control rotation of the second leg assembly with respect to the mounting assembly,
- wherein when folded, the first and second leg assemblies are disposed in an interior defined by the mounting assembly and are substantially on a same plane as the mounting assembly;
- wherein the mounting assembly further comprises third and fourth mounting members, each connected to or integrally formed with the first and second mounting members, wherein the third and fourth mounting members are spaced apart from each other with the third mounting member disposed at the first side of the mounting assembly and the fourth mounting member disposed at the second side of the mounting assembly;
- wherein a respective leg assembly in the first and second leg assemblies is pivotally connected with the mounting assembly by one or more mounting couplers connected to or integrally formed with a corresponding mounting member in the third and fourth mounting members;
- and
- wherein:
- each of the one or more mounting couplers comprises one or more lugs;
- and
- the respective leg assembly comprises one or more legs, wherein each respective leg in the one or more legs is pivotally coupled with the one or more lugs of a corresponding coupler in the one or more couplers by a fastener through openings formed at the one or more lugs and at the respective leg.
