Abstract

A mobile sanitation that includes at least one conventional self-contained chemical toilet and at least one hand washing system that are mounted together onto a flat bed of a trailer. The self-contained chemical toilet or toilets are arranged to gravity drain through a common line and the hand washing system includes a housing with a sealed bottom end that is secured onto the trailer flat bed to be positioned alongside the chemical toilet or toilets. The hand washing system housing includes a divider plate secured thereacross forming the housing into a fresh water reservoir that is accessed through the housing top end, a hand washing section that is accessed through an opening in the housing, that includes a drain plate secured across the housing as a bottom of the hand washing section, and with a dirty water reservoir as the housing bottom portion. The fresh water reservoir gravity feeds water through a tube that connects to a manually operated valve within the hand washing section that is operated to pass water through a nozzle and onto a person'"'"'s hands positioned therein, with that water then traveling into the dirty water reservoir wherein it is held for later disposal. A movable door is provided for sliding across the housing opening into the hand washing section that can be locked in a covering attitude.

Claims

1. A mobile sanitation system comprising, a trailer having a frame covered by a flat bed and including means for connection to a towing vehicle;

at least one self-contained chemical toilet mounted on said trailer flat bed;

a hand washing system that includes a housing that is a straight cylinder mounted at a lower end onto said trailer flat bed and includes an opening formed into mid-portion of said cylinder interior to receive a person'"'"'s hands passed therein into said cylinder interior, with an upper portion of said cylinder formed as a fresh water reservoir to gravity feed clean water through a hose to a manually operated valve located within said cylinder mid-portion that is operated to dispense said clean water through a nozzle, and said cylinder mid-portion includes a washing section base plate secured across as a top of a cylinder closed bottom section and wherein a dirty water drain is formed; and

a door for fitting over the opening into the cylinder mid-portion that is a rectangular plate formed to the shape of the straight tube outer surface and has opposing parallel sides that are formed to fit into so as to slide along a pair of straight tracks that are secured along opposite vertical sides of said opening and extend below said washing section base plate.

2. A mobile sanitation system as recited in claim 1, wherein the cylinder extends vertically alongside the self-contained chemical toilet and includes a flat divider plate that is mounted across a top of the cylinder mid-portion separating the fresh water reservoir from said cylinder mid-portion, with access to said fresh water reservoir provided through a cylinder top end plate;

and the washing section base plate extends across said cylinder adjacent to and as a bottom of said hand washing section having the dirty water drain centered therein and with a flat section of a mesh material positioned over said dirty water drain.

3. A mobile sanitation system as recited in claim 2, wherein the flat divider plate includes a standpipe with holes therein to pass water into said standpipe and is mounted at approximately a right angle vertically from said plate and passes through the cylinder top portion and top end as an air release means and connects to a top end of the hose, with said hose having a bottom end connected to the manually operated valve that is secured onto the flat divider plate and includes a nozzle end and an arm that is pivotally mounted thereto that is manually depressed to open said valve to pass water through said nozzle end.

4. A mobile sanitation system as recited in claim 3, where the nozzle end is a tube secured to and extending from the valve and is positioned to dispense the fresh water within the cylinder mid-portion.

5. A mobile sanitation system as recited in claim 4, wherein the nozzle end is curved back upon itself;

and a drain line is mounted at one end into the cylinder bottom section and outwardly extends from the cylinder outer surface to approximately the trailer frame; and

a discharge valve that is maintained in said drain line for operation to gravity drain collected dirty water.

6. A mobile sanitation system as recited in claim 1, wherein at least a pair of portable chemical toilets are mounted onto the trailer bed, in side-by-side relationship, with the hand washing system mounted between said pair of portable chemical toilets and adjacent to doors of said portable chemical toilets.

7. A mobile sanitation station comprising, a trailer having a frame covered by a flat bed and including means for connection to a towing vehicle;

at least one self-contained chemical toilet mounted on said trailer flat bed;

a hand washing system that includes a housing that is a straight cylinder that is mounted at a lower end onto said trailer flat bed and includes an opening formed into a mid-portion of said cylinder interior to receive a person'"'"'s hands passed therein into said cylinder interior, with an upper portion of said cylinder formed as a fresh water reservoir to gravity feed clean water through a connected hose to a manually operated valve located within said cylinder mid-portion that is operated to dispense clean water through a nozzle, and said cylinder mid-portion includes a washing section base plate as a top of a cylinder closed bottom section wherein a dirty water drain is formed; and

a ladder frame secured at its ends to the flat bed and is bent through two right angles to extend alongside and across the self-contained chemical toilet and the hand washing system.

8. A mobile sanitation system as recited in claim 7, wherein the cylinder extends vertically alongside the self-contained chemical toilet and includes a flat divider plate that is mounted across a top of the cylinder mid-portion separating the fresh water reservoir from said cylinder mid-portion, with access to said fresh water reservoir provided through a cylinder top end plate;

and the washing section base plate extends across said cylinder adjacent to and as a bottom of said hand washing section having the dirty water drain centered therein and including a flat section of a mesh material positioned over said dirty water drain.

9. A mobile sanitation system as recited in claim 8;

wherein the flat divider plate includes a standpipe with holes therein to pass water into said standpipe and is mounted at approximately a right angle vertically and passes through the cylinder top portion and top end as an air release means and connects to a top end of the hose, with said hose having a bottom end connected to the manually operated valve that is secured onto the flat divider plate and includes a nozzle end and an arm that is pivotally mounted thereto that is manually depressed to open said valve to pass water through said nozzle end.

10. A mobile sanitation system as recited in claim 9, where the nozzle end is a tube secured to and extending from the valve and is positioned to dispense the fresh water within the cylinder mid-portion.

11. A mobile sanitation system as recited in claim 10, wherein the nozzle end is curved back upon itself;

and a drain line is mounted at one end into the cylinder bottom section and extends outwardly from the cylinder outer surface to approximately the trailer frame; and

a discharge valve that is maintained in said drain line for operation to gravity drain collected dirty water.

12. A mobile sanitation system as recited in claim 7, wherein at least a pair of portable chemical toilets are mounted onto the trailer bed, in side-by-side relationship, with the hand washing system mounted between said pair of portable chemical toilets and adjacent to doors of said portable chemical toilets.
