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;
- and
- 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 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, wherein the plurality of bars comprises:
- a first bar at a first side of the upper frame;
- a second bar at a second side of the upper frame;
- a third bar at a third side of the upper frame;
- and
- a fourth bar at a fourth side of the upper frame;
- and
- a plurality of legs to support the upper frame when unfolded, the plurality of legs comprising:
- a first leg having an upper end rotatably coupled with the first bar such that the first leg is rotatable toward or away from the third bar;
- a second leg having an upper end rotatably coupled with the second bar such that the second leg is rotatable toward or away from the fourth bar;
- a third leg having an upper end rotatably coupled with the third bar such that the third leg is rotatable toward or away from the first bar;
- and
- a fourth leg having an upper end rotatably coupled with the fourth bar such that the first leg is rotatable toward or away from the second bar,
- wherein when folded, the first, second, third and fourth legs are disposed in an interior defined by the upper frame.
A foldable supporting frame comprising:
- an upper frame comprising first, second, third and fourth bars disposed at first, second, third and fourth sides of the upper frame, respectively, wherein:
- adjacent bars in the first, second, third and fourth bars are coupled to each other or integrally formed with each other at adjacent end portions thereof;
- and
- the upper frame has a substantially square shape;
- and
- first, second, third, and fourth legs disposed below the upper frame when unfolded to support the upper frame, wherein:
- the first leg has an upper end rotatably coupled with the first bar;
- the second leg has an upper end rotatably coupled with the second bar;
- the third leg has an upper end rotatably coupled with the third bar;
- the fourth leg has an upper end rotatably coupled with the fourth bar;
- and
- each leg in the first, second, third and fourth legs is rotatable independently from other legs in the first, second, third and fourth legs,
- wherein, when folded, the first, second, third and fourth legs collectively form a substantially square shape within the square shape of the upper frame.
