US Patent 11946591 Foldable stand

A foldable stand has a base, a riser, and a switching mechanism. The riser is located on the base. The switching mechanism connects the base and the riser such that the riser selectively pivots relative to the base from an upright position to a folded position. The switching mechanism has a locked status and a released status. In the locked status, the switching mechanism prevents the riser from pivoting relative to the base. In the released status, the switching mechanism allows the riser to pivot relative to the base from an upright position to a folded position. The switching mechanism is configured to be switched from the locked status to the released status by rotation of the riser around a centerline of the riser.
