PORTABLE TUB
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.
This application claims the benefit of and incorporates by reference U.S. Provisional Application No. 60/124,826 filed Feb. 25, 2008, and U.S. Provisional Application No. 60/075,365, filed Jun. 25, 2008.
FIELD OF THE INVENTIONThis specification relates to the field of health and hygiene, and more particularly to a portable tub.
BACKGROUNDMuch of the prior art in this field addresses the problem of bathing an individual confined to a bed. For example, U.S. Pat. No. 6,088,848 describes a modular portable shower with an impermeable liner and a modular frame that permits one to shower a bedridden person; U.S. Pat. No. 5,909,970 describes a portable bathing apparatus to be used on a mattress and being collapsible for efficient storage and transportation; U.S. Pat. No. 4,485,502 describes a portable bathing tub for invalids, especially bed-ridden persons. These inventions require the user to lie down in the portable tub during bathing and are ill-suited for use by persons who may have difficultly lying down to bathe.
Other prior art teaches various forms of tubs, some intended for use with shower stalls. U.S. Pat. No. 2,420,448 teaches a telescopic bathtub, with an extended position for use. When the bathtub is in the extended position, its configuration is essentially the same as an ordinary bathtub it and functions the same as an ordinary bathtub. As such, a user must climb over the walls to enter the bathtub and lie down in the tub to bathe. U.S. Pat. No. 4,970,734 discloses an apparatus for converting a rectangular shower stall booth into a bath. The apparatus comprises a rigid frame mounted to the shower stall and a waterproof insert to retain water. This bathtub extends out of the shower and, among other things, will not work with a non-rectangular shower stall. Finally, U.S. Pat. No. 4,337,540 teaches a portable, lightweight free-standing tub accessory for use in conventional shower stalls. However, this portable tub is not collapsible for easy storage.
SUMMARY OF THE INVENTIONIn one aspect, a portable shower tub provides an upright enclosure for water to allow a person to bathe in without a fixed tub. The portable shower tub may be of various designs, including a collapsible design formed of telescoping slats concentrically arranged or a ribbed structure with a liner. A liner may be formed of an antimicrobial substance and/or treated with a mold inhibitor to promote sanitary use.
A portable tub may be useful for allowing a person to bathe in a standard shower or tub. A portable tub may be constructed so that it may be placed in a shower or bathtub and pulled up around the bathing person and then fixed in an extended state. The bathing person may then fill the portable tub with water and bathe. This will allow the person bathing to have the benefits of immersion in warm water without having to lie down in a conventional bathtub. This may be particularly useful for individuals who are elderly or handicapped, and who have difficulty lying down in a conventional bathtub.
A portable tub will now be described with more particular reference to the attached drawings. Hereafter, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments. Throughout this disclosure, a hyphenated form of a reference numeral refers to a specific instance or example of an element and the un-hyphenated form of the reference numeral refers to the element generically or collectively. Thus, for example, 102-1 may refer to a “pen,” which may be an instance or example of the class of “writing implements.” Writing implements may be referred to collectively as “writing implements 102” and any one may be referred to generically as a “writing implement 102.”
In an alternative to the embodiment shown in
While the subject of this specification has been described in connection with one or more exemplary embodiments, it is not intended to limit the claims to the particular forms set forth. On the contrary, the appended claims are intended to cover such alternatives, modifications and equivalents as may be included within their spirit and scope.
Claims
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.
