Portable pedestal pan

Abstract

The present invention is a portable pedestal pan—a specially designed structure that is used in places without interior bathrooms or where going to the bathroom is inconvenient (such as outdoors, in hospital wards, and in the vehicle) and that is easily portable. The present invention comprises a top board, a vertically retractable supporting mechanism that is set under the top board, wherein the supporting mechanism is equipped with a caging device for locking upon retraction. The supporting mechanism optionally has a bottom board 14 that is set underneath the supporting mechanism and is connected to it. The top board is optionally a ring with a hole in the middle. When the invention is used, the supporting mechanism under the top board is vertically unfolded, and is locked by the caging device, and a scrap bag is sleeved onto the top board. After use, the scrap bag is taken off. The supporting mechanism is folded. The present invention is easy to carry and reuse.
