Abstract
A portable wash station, comprising an outer water tank, a flexible inner water tank secured within the outer tank, and a sink basin affixed atop the outer tank including at least one sink, one water faucet for dispensing water from the outer tank and one drain for draining water from the sink into the inner tank. The flexible inner tank has an associated volume that expands as the water is dispensed from the outer tank and into the flexible inner tank, that contracts as the water is removed therefrom, and that is subjected to minimal hydraulic pressure from the water dispensed therein.
Claims14
A portable wash station, comprising:
- an outer water tank for holding a volume of fresh water;
- a flexible inner water tank secured within said outer tank;
- and
- a sink basin affixed atop said outer tank including at least one sink, one water faucet for dispensing water from said outer tank, and one drain for draining water from said sink into said inner tank;
- said flexible inner tank having an associated volume that expands as said water is dispensed from said outer tank and into said flexible inner tank, and that contracts as said water is removed therefrom, said flexible inner tank being immersed in said volume of fresh water held in said outer water tank to minimize hydraulic pressure thereon.
A water storage system for a wash station having at least one water faucet, one sink, and one drain, comprising:
- a rigid outer tank defining a water retaining cavity for storing unused fresh water, said rigid outer tank having a plurality of flanges around its periphery;
- and
- a flexible inner tank for storing water dispensed from said rigid outer tank, said inner tank having an associated volume that contracts when said inner tank is emptied and that expands when said inner tank is filled;
- said inner tank having a retaining band around its periphery having an associated thickness greater than that of said inner tank and that includes a plurality of retainers for cooperatively engaging with said outer tank flanges for maintaining said inner tank within said outer tank water retaining cavity.
A portable wash station, comprising:
- a rigid outer water tank for directly holding a volume of fresh water dispensed therein whereby water in said rigid outer water tank is in direct contact with sidewalls of said rigid outer water tank;
- a flexible inner water tank seated within said rigid outer tank and secured to said rigid outer water tank by an inner tank retainer whereby water in said outer rigid water tank is able to directly contact an outer surface of said flexible inner water tank;
- a sink basin affixed over said inner and outer tanks including at least one sink, at least one water faucet for dispensing water from said outer water tank into said at least one sink and at least one drain for draining water from said sink and into said flexible inner tank;
- said flexible inner tank having an associated volume that increases as said water is dispensed from said outer tank into said flexible inner tank, and that decreases as said water is removed from said flexible inner tank;
- a disposal access port defined in said sink basin allowing access to said flexible inner tank for removal of said water from said flexible inner tank;
- said disposal access port including a disposal access port lid lockably engaged with said sink basin;
- and
- a foot pump operatively coupled to said faucet and said outer tank for controlling dispensing of said water through said faucet.
