Abstract

An apparatus for insertion within a bathtub defined by spaced parallel side walls, a floor coextensive with the side walls, and a rear wall mounting a cushion at an upper terminal end thereof directed orthogonally between the side walls. The side walls are pneumatically or fluidly filled within chambers formed in the side walls, wherein the floor includes a chamber for filling overlying a lower chamber filled with a granular material to effect stable positioning of the organization in use. Suction cup members are mounted coextensively along the floor, side walls, and cushion for securement to an interior surface of an associated bathtub.

Claims

1. A bathtub liner comprising, in combination,

an elongate, generally rectangular floor member, the floor member including a left wall mounted hingedly and coextensively to a left edge of the floor member, and a right wall mounted hingedly and coextensively to a right edge of the floor member, and

a rear wall orthogonally oriented relative to the left wall and right wall hingedly mounted at its lower terminal edge to a top surface of the floor member spaced from a rear terminal edge of the floor member, and the rear wall including a cushion member coextensively mounted to an upper terminal edge of the rear wall, and

the left wall and the right wall each define a chamber therewithin, wherein each chamber is directed coextensively of the left and right wall, and the left wall includes a left wall fill tube and the right wall includes a right wall fill tube each communicating with the respective chambers and the left wall fill tube includes a first valve therein and the right wall fill tube includes a second valve therein, and the left wall fill tube includes a wall fill tube connector block connected to a terminal end thereof, the wall fill tube connector block having a connector plug receiving a free terminal end of the right wall fill tube thereto, and

the first and second valves each include a housing, and each housing includes a rotatable valve member positioned therewithin, each valve member including an axle, wherein the axle projects through the housing, and each axle mounts an adjustment disk orthogonally thereto to permit rotation of the valve member, and the valve member includes a planar wall diametrically directed through the valve member to permit selective blockage and free flow of pneumatic gas or fluid through each valve, and

the floor member includes an upper chamber arranged coextensively with the floor, wherein the upper chamber includes a plurality of floor fill nozzles in fluid communication with the upper chamber, wherein each of the floor fill nozzles are arranged for reception of fluid filling of the upper chamber, and the floor member further including a lower chamber coextensive with the floor member and underlying the upper chamber, wherein the lower chamber is filled with a granular material effecting stability of the apparatus when positioned within a bathtub, and

the left wall includes a series of left wall suction cups mounted thereto, the right wall includes a series of right wall suction cups mounted thereto, and the floor member includes a series of floor member suction cups mounted thereto for securement of the left wall, right wall, and floor member to interior surfaces of the associated bathtub, and the cushion includes a series of cushion suction cups mounted to the cushion on a rear surface thereof for securement of the cushion to a surface of the associated bathtub, and

the left wall includes a plurality of first magnetic strips mounted within the left wall adjacent an upper terminal end thereof, and the right wall includes a plurality of second magnetic strips mounted within the right wall adjacent an upper terminal end thereof, and

the floor member includes a connector strap mounted medially to a bottom surface of the floor member, and a first hook and loop fastener patch mounted to the bottom surface of the floor member, adjacent the rear terminal edge thereof, and the connector strap includes a second hook and loop fastener patch at a free terminal end of the connector strap for securement to the first hook and loop fastener patch when the rear wall, the left wall, and the right wall are in an interfolded relationship relative to the floor member.
