Abstract
A foldable supporting frame includes an upper frame and a plurality of legs disposed below the upper frame when unfolded to support the upper frame. The upper frame includes a plurality of bars, with adjacent bars in the plurality of bars coupled to each other or integrally formed with each other at their adjacent end portions. Each of the plurality of legs is coupled with a corresponding bar in the plurality of bars and independently rotatable about an axis defined by the corresponding bar. When folded, the plurality of legs is disposed in an interior defined by the upper frame.
Claims20
A foldable supporting frame comprising:
- an upper frame comprising a plurality of bars, wherein adjacent bars in the plurality of bars are coupled to each other or integrally formed with each other at adjacent end portions thereof;
- a plurality of legs disposed below the upper frame when unfolded to support the upper frame, wherein each of the plurality of legs is coupled with a corresponding bar in the plurality of bars and independently rotatable about an axis defined by the corresponding bar in the plurality of bars, wherein when folded, the plurality of legs are disposed in an interior defined by the upper frame;
- and
- a plurality of couplers to couple the plurality of legs with the upper frame, wherein each respective coupler in the plurality of couplers comprises a rotating portion rotatably coupled with a corresponding bar in the plurality of bars and a fixation portion fixedly coupled or integrally formed with the upper end portion of a corresponding leg in the plurality of legs;
- wherein at least a portion of the corresponding bar is circular, and the rotating portion of the respective coupler sleeves on the circular portion of the corresponding bar;
- wherein the rotating portion of the respective coupler comprises a slot on a side wall thereof, wherein the slot is operably coupled with a guiding post at the corresponding bar to prevent the respective coupler from sliding along a length of the corresponding bar and to guide rotation of the corresponding leg about the axis defined by the corresponding bar.
A foldable supporting frame comprising:
- an upper frame comprising a plurality of bars, wherein adjacent bars in the plurality of bars are coupled to each other or integrally formed with each other at adjacent end portions thereof;
- a plurality of legs disposed below the upper frame when unfolded to support the upper frame, wherein each of the plurality of legs is coupled with a corresponding bar in the plurality of bars and independently rotatable about an axis defined by the corresponding bar in the plurality of bars, wherein when folded, the plurality of legs are disposed in an interior defined by the upper frame;
- a plurality of sliders, each movably disposed at one of a corresponding bar in the plurality of bars and a corresponding leg in the plurality of legs;
- and
- a plurality of oblique supports, each having a first end portion pivotally connected with a corresponding slider in the plurality of sliders and a second end portion pivotally connected with the other of the corresponding bar in the plurality of bars and the corresponding leg in the plurality of legs.
