Abstract
A foldable stand includes first and second supports, each having first and second portions. The foldable stand also includes first and second leg assemblies, each having a pair of crossed bars. The pair of crossed bars of the first leg assembly is pivotally connected to the first portions of the first and second supports. The pair of crossed bars of the second leg assembly is pivotally connected to the second portions of the first and second supports. The foldable stand further includes at least one locking assembly to selectively lock the pair of crossed bars of the first or second leg assembly to prevent the foldable stand from accidental folding.
Claims18
A foldable stand comprising:
- a first support and a second support, each comprising a first portion and a second portion;
- a first leg assembly and a second leg assembly, each comprising a pair of crossed bars, wherein:
- an upper end of a first crossed bar in the pair of crossed bars of the first leg assembly is pivotally connected to the first portion of the second support;
- an upper end of a second crossed bar in the pair of crossed bars of the first leg assembly is pivotally connected to the first portion of the first support;
- an upper end of a first crossed bar in the pair of crossed bars of the second leg assembly is pivotally connected to the second portion of the second support;
- and
- an upper end of a second crossed bar in the pair of crossed bars of the second leg assembly is pivotally connected to the second portion of the first support;
- and
- at least one locking assembly to selectively lock the pair of crossed bars of the first or second leg assembly, thereby allowing the foldable stand to fold and unfold when unlocked and preventing the foldable stand from accidental folding when locked;
- wherein the at least one locking assembly comprises a first locking assembly connected to the pair of crossed bars of the first leg assembly to selectively lock the pair of crossed bars of the first leg assembly relative to each other, and
- wherein the first locking assembly comprises:
- a first locking bar pivotally connected to the first crossed bar in the pair of crossed bars of the first leg assembly;
- a second locking bar pivotally connected to the second crossed bar in the pair of crossed bars of the first leg assembly, wherein the first and second locking bars are movably coupled with each other, thereby allowing the first locking assembly to adjust its length;
- and
- a locking/unlocking mechanism to selectively restrict the first and second locking bars from moving with respect to each other.

A foldable stand comprising:
- a first support and a second support;
- a first leg assembly and a second leg assembly connected to the first and second supports for supporting the first and second supports when the foldable stand is unfold, the first or second leg assembly comprising a first bar, a second bar, a first leg and a second leg, wherein:
- the first and second bars are pivotally connected with each other at middle portions thereof;
- an upper end of the first bar is pivotally connected to the second support;
- an upper end of the second bar is pivotally connected to the first support;
- an upper end of the first leg is pivotally connected to the first support and spaced apart from the upper end of the second bar along a length direction of the first support;
- an upper end of the second leg is pivotally connected to the second support and spaced apart from the upper end of the first bar along a length direction of the second support;
- a lower end of the first bar and a lower end of the first leg are pivotally connected to each other;
- and
- a lower end of the second bar and a lower end of the second leg are pivotally connected to each other;
- and
- a locking assembly having a first end pivotally connected to the first bar and a second end pivotally connected to the second bar, wherein the locking assembly has a length that is selectively adjustable, thereby allowing the foldable stand to fold and unfold and preventing the foldable stand from accidental folding.
