Portable tub

Abstract

A portable shower tub provides an upright enclosure to allow a person to bathe without a fixed tub. The portable shower tub may be a collapsible design formed of telescoping slats concentrically arranged to form substantially a semi-cone. The slats may be configured to interlock with a watertight seal, or a liner may be suspended from the rim to hold water. A liner may be formed of an antimicrobial substance and/or treated with a mold inhibitor to promote sanitary use.

1 . A portable tub comprising:
 a lightweight collapsible outer shell adapted to:
 render the portable tub easily movable when in a collapsed state; and 
 hold a volume of water when in an extended state; 
   a watertight inner surface; and   a closeable drain hole.   
   
   
       2 . The portable tub of  claim 1  wherein the shell comprises a plurality of concentric slats. 
   
   
       3 . The portable tub of  claim 2  wherein the slats are circular. 
   
   
       4 . The portable tub of  claim 2  wherein the watertight inner surface comprises inner surfaces of the slats and a seal on junctions between the slats. 
   
   
       5 . The portable tub of  claim 1  wherein the watertight inner surface is a liner. 
   
   
       6 . The portable tub of  claim 5  wherein the liner is suspended from a rim of the shell. 
   
   
       7 . The portable tub of  claim 1  wherein the shell comprises a plurality of rigid ribs and wherein the watertight inner surface is a liner suspended between the ribs. 
   
   
       8 . The portable tub of  claim 7  further comprising a strap operable to affix to at least one of the ribs and adapted to be supported by a fixed supporting structure. 
   
   
       9 . The portable tub of  claim 7  further comprising a structural frame adapted to support the ribs when in an extended state. 
   
   
       10 . The portable tub of  claim 9  wherein the structural frame comprises a telescoping rod. 
   
   
       11 . The portable tub of  claim 9  wherein the structural frame comprises a folding rod. 
   
   
       12 . The portable tub of  claim 9  wherein the structural frame comprises a fixed rod and a bracket 
   
   
       13 . The portable tub of  claim 12  wherein the bracket includes a slider adapted to slide on the fixed rod and a mounting pin adapted to engage the fixed rod. 
   
   
       14 . The portable tub of  claim 1  further comprising an immersible chair. 
   
   
       15 . The portable tub of  claim 14  wherein the immersible chair includes jets. 
   
   
       16 . An immersible chair for use with a portable tub, the immersible chair comprising:
 a chair constructed substantially of non-reactive material;   jets configured to provide water pressure; and   a power source.   
   
   
       17 . The immersible chair of  claim 16  wherein the power source is a rechargeable battery secured in a watertight compartment. 
   
   
       18 . The immersible chair of  claim 16  wherein power source includes a fuse configured to suppress transient currents. 
   
   
       19 . The immersible chair of  claim 18  wherein the fuse is configured to suppress transient currents greater than 10 mA.
