Abstract
Abstract A water jet massage apparatus comprises a platform having a bench mounted thereon, and an overlying lid arranged for pivotal movement between an open position in which a person may gain access to the bench and a closed position in which the lid is lowered onto the bench. The lid includes top, front, rear, and opposite side walls, and also has a bottom wall formed of flexible, water-proof material which drapes over and covers a person reclining on the bench when the lid is closed. The water-tight cavity in the lid defined by the aforementioned walls contains a laterally extending, longitudinally movable water manifold which mounts and supplies water to a plurality of pulsating water jet spray heads which direct a multitude of pulsating jets of water downward onto the flexible bottom wall which loosely covers a person reclining on the bench, keeping him dry. Spent water from the water jet heads finds its way to side gutters in the chamber whereupon the water drains from the water-tight cavity into a holding tank where it is reheated and recycled continuously. The effect is a multitude of pulsating massaging water jets impinging on the flexible material draped across the body, the spray head assembly also moving longitudinally through the chamber from head to toe or any desired portion thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
179 words
A water jet massage apparatus comprising: (a) a base (b) an elongated bench on the base configured to permit a person to recline thereon, (c) an elongated lid having top, front, rear and ppposite side walls and a flexible bottom wall of water-proof sheet material forming an elongated water-tight chamber thereinbetween, positioning means for arranging the lid in a juxtapose spaced overlying relationship with the bench with said flexible bottom wall sheet configured to loosely overlie and conform to the top surface contour of the body of a person reclining on the bench, (d) at least one water jet head contained within said water-tight chamber, the head having a plurality of water jet spray orifices directed to impact jets of water under pressure directly against said flexible bottom wall sheet, (e) water supply means communicating with said orifices for delivering pulsating jets of water under pressure through said orifices and impacting said pulsating jets of water against said bottom wall sheet, and (f) water drain means in said lid to drain water expelled into said chamber through said orifices.
Claim 2
Dependent Claim
