A foldable treadmill includes a base for running or walking, a frame set pivotally connected with the base, and a folding mechanism for folding the frame set. The folding mechanism has a control assembly comprising a knob and a first bolt controlled by the knob. When a part of the first bolt is arranged inside the frame set, the frame set cannot be folded, and when the first bolt is moved out of the frame set, the frame set can be folded to a storage configuration.

A director's chair includes two support frames and two cross rod assemblies connected to the front ends and rear ends of the two support frames. The director's chair is folded or unfolded by controlling support rods of the cross rod assemblies to be folded or unfolded. The height of the folded director's chair is only the height of leg rods of the support frames. An armrest rod, a seat rod and a backrest rod of the support frame can be folded at the side of the leg rods, so that the size of the director's chair is small enough to facilitate the storage and transportation.

The invention provides a panel capable of being rapidly folded and unfolded. The panel comprises a plurality of unit plates which are connected with each other and can fold relative to each other, so the panel can be folded and unfolded between a folded state and an unfolded state in a Miura pliage method. The panel is characterized in that actuating devices are arranged among the unit plates. The actuating devices are elastic devices or magnetic devices. The actuating devices can apply elastic forces or magnetic forces on adjacent unit plates, so that the unit plates are unfolded or folded relative to each other. Thus, the panel can be automatically unfolded to the unfolded state or folded to the folded state in the Miura pliage method.
