Abstract
A foldable frame with enhanced stability includes a mounting assembly, a first leg assembly and a second leg assembly. Each of the first and second leg assemblies are pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position. Each of the first and second leg assemblies includes a substantially straight first leg and a substantially straight second leg. The first and second legs are slanted outwardly to increase the supporting area and thus enhance the stability of the foldable frame and stability of other structures supported by the foldable frame.
Claims17
A frame comprising:
- a mounting assembly;
- first and second leg assemblies, each pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position, wherein:
- each of the first and second leg assemblies comprises a first leg, a second leg, and a lateral leg bar;
- an upper end portion of the first leg of a respective leg assembly in the first and second leg assemblies is pivotally connected to the mounting assembly at a first position;
- an upper end portion of the second leg of the respective leg assembly is pivotally connected to the mounting assembly at a second position;
- at least a majority portion of each of the first and second legs of the respective leg assembly is substantially straight;
- the lateral leg bar of the respective leg assembly connects the first and second legs of the respective leg assembly and has a length between the first and second legs of the respective leg assembly that is greater than a distance between the first position and the second position such that the first and second legs of the respective leg assembly are slanted outwardly relative to each other at a first angle;
- in the use position, the first legs of the first and second leg assemblies or the second legs of the first and second leg assemblies are slanted outwardly relative to each other at a second angle;
- and
- in the storage position, the first and second assemblies are folded toward the mounting assembly;
- and
- first and second supporting assemblies to control rotation of the first and second leg assemblies with respect to the mounting assembly or help stabilize the first and second leg assemblies when they are in the use position, wherein each of the first and second supporting assemblies comprises:
- a first supporting member having an end pivotally coupled with the first or second leg assembly;
- 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 pivotally coupled with the slider and another end pivotally coupled with the mounting assembly.

A frame comprising:
- a mounting assembly comprising:
- a first longitudinal mounting member and a second longitudinal mounting member spaced apart from each other;
- a first lateral mounting member and a second lateral mounting member spaced apart from each other and coupled with the first and second longitudinal mounting members;
- and
- a plurality of couplers disposed at the first and second lateral mounting members;
- and
- first and second leg assemblies, each comprising a first leg and a second leg pivotally coupled with the mounting assembly by the plurality of couplers disposed at the first or second mounting member, and rotatable with respect to the mounting assembly between a use position and a storage position, wherein:
- at least a majority portion of each of the first and second legs is substantially straight;
- the first and second legs of the first or second leg assembly are slanted outwardly relative to each other at a first angle;
- in the use position, the first legs of the first and second leg assemblies or the second legs of the first and second leg assemblies are slanted outwardly relative to each other at a second angle;
- and
- in the storage position, the first and second assemblies are folded toward the mounting assembly.
