Abstract

Abstract A portable shampoo unit utilizes a back rest, whose face is covered with a water impervious resilient material hingeably secured to a frame. Both frame and back rest being adapted for resting on a supporting surface such as a bed. A shampoo tray is hingeably affixed to the frame such that the front edge of the tray, in one extreme position, overhangs the back rest and is maintained in substantially a horizontal position and in the other extreme position, is caused to have the rearmost portion of the tray directed downwardly and outwardly of the frame into the open mouth portion of a chamber carried by the frame. The chamber drains into a tank carried by a portable cart utilizing a flexible hose therefor. The cart also carries a fresh water tank which flexibly communicates to a spray nozzle for application of water to the head of a user disposed resting on the padded front edge of the tray, when the tray is in a horizontal position. Upon the user disengaging contact with the tray, the tray automatically tilts rearwardly disgorging the water stored therewithin into the chamber.
