Abstract

A portable sanitary facility is disclosed which, in one embodiment is particularly adapted for use by males needing only to relieve themselves of liquid body wastes. A sanitary unit is carried by a trailer to achieve portability between a use station and a disposal site. The sanitary unit includes a main compartment more or less encompassed by a trough with apertures being provided in the compartment walls to drain liquid introduced into the trough into the compartment interior. The main compartment is divided into a plurality of sub-compartments by transverse vertical baffles which include a series of apertures for establishing liquid communication between the subcompartments. The baffles serve to prevent shifting of the liquid load and thus stabilize the trailer during transport to a disposal site. A valved outlet is provided to permit draining the facility at a disposal site. Removable access covers permit entry into the facility interior during fabrication, maintenance and cleaning. In a second female or all-purpose embodiment a plurality of toilet seats and aperture over each subcompartment are provided in the top of the compartment to receive solid and liquid wastes, and modesty apartment means enclose each seat to give privacy. Means for converting solid waste to liquid waste are provided.

Claims

1. A portable sanitary facility for males comprising:

(A) a trailer;

said trailer including;

1. a trailer frame;

2. wheels disposed on both sides of and at least partially supporting said trailer and frame;

3. a forwardly extending trailer hitch adapted to couple the trailer to a towing vehicle;

(B) a sanitary unit carried by said trailer;

said sanitary unit comprising;

1. a main compartment having a top, a bottom, fore and aft end walls, and left and right side walls, said walls collectively defining a periphery of said main compartment;

2. a trough comprising a bottom and an outer lip having an upper edge;

said trough being fixed to and extending about at least a portion of said main compartment periphery and cooperating therewith to define a liquid receiving receptacle; and

3. a plurality of apertures in said walls disposed adjacent said trough and vertically situated in said walls within a region which is higher than said trough bottom and lower than said upper edge of said trough lip;

whereby liquid introduced into said receptacle drains into said main compartment for retention therein such that said facility may be later towed to a disposal site for disposal of the retained liquid.

2. The portable sanitary facility of claim 1 which further includes inside said main compartment:

(A) at least one fore and aft vertical baffle extending between said fore and aft end walls;

(B) at least one side to side vertical baffle extending between said left and right side walls;

(C) said fore and aft vertical baffle and said side to side vertical baffle joining intermediate their respective lengths to define, in conjunction with said fore and aft end walls and said left and right side walls, a plurality of sub-compartments in said main compartment.

3. The portable sanitary facility of claim 2 in which a plurality of apertures are provided in said vertical baffles to establish liquid communication between all adjacent sub-compartments.

4. The portable sanitary facility of claim 3 which includes

(A) an outlet for establishing liquid communication between the interior and the exterior of said main compartment;

and

(B) a valve in said outlet for selectively opening and closing said outlet;

whereby said outlet may be closed off during use of the facility and during transport of the facility to a disposal site and may be opened to drain the liquid contents from said main compartment at the disposal site.

5. A portable sanitary facility comprising:

(A) a trailer;

said trailer including;

1. a trailer frame;

2. wheels disposed on both sides of and at least partially supporting said trailer and frame;

3. a forwardly extending trailer hitch adapted to couple the trailer to a towing vehicle;

(B) a sanitary unit carried by said trailer;

said sanitary unit comprising;

7. The portable sanitary facility of claim 5 in which a plurality of apertures are provided in said vertical baffles to establish liquid communication between all adjacent sub-compartments.

6. a main compartment having a top, a bottom, fore and aft end walls, and left and right side walls, said walls collectively defining a periphery of said main compartment;

said top having at least one means defining a toilet seat and toilet seat aperture communicating with said main compartment.

2. at least one fore and aft vertical baffle extending between said fore and aft end walls;

3. at least one side to side vertical baffle extending between said left and right side walls;

4. said fore and aft vertical baffle and said side to side vertical baffle joining intermediate their respective lengths to define, in conjunction with said fore and aft end walls and said left and right side walls, a plurality of sub-compartments in said main compartment.

8. The portable sanitary facility of claim 6 which includes

(A) an outlet for establishing liquid communication between the interior and the exterior of said main compartment;

and

(B) a valve in said outlet for selectively opening and closing said outlet;

whereby said outlet may be closed off during use of the facility and during transport of the facility to a disposal site and may be opened to drain the liquid contents from said main compartment at the disposal site.

11. The portable sanitary facility of claim 8 in which a plurality of apertures are provided in said vertical baffles to establish liquid communication between all adjacent sub-compartments.

9. A portable sanitary facility comprising:

I. a trailer;

said trailer including;

a. a trailer frame;

b. wheels disposed on both sides of and at least partially supporting said trailer and frame;

c. a forwardly extending trailer hitch adapted to couple the trailer to a towing vehicle;

II. a sanitary unit carried by said trailer;

said sanitary unit comprising;

a. a male section comprising;

1. a main compartment having a top, a bottom, fore and aft end walls, and left and right side walls, said walls collectively defining a periphery of said main compartments;

2. a trough comprising a bottom and an outer lip having an upper edge;

said trough being fixed to and extending above at least a portion of said main compartment periphery and cooperating therein to define a liquid receiving receptacle; and

3. a plurality of apertures in said walls disposed adjacent said troughs and vertically situated in said walls within a region which is higher than said trough bottom and lower than said upper edge of said trough lip;

whereby liquid introduced into said receptacle drains into said main compartment for retention therein such that said facility may be later towed to a disposal site for disposal of the retained liquid; and

b. a female or general purpose section comprising;

12. The portable sanitary facility of claim 9 which includes

(A) an outlet for establishing liquid communication between the interior and the exterior of said main compartment;

and

(B) a valve in said outlet for selectively opening and closing said outlet;

whereby said outlet may be closed off during use of the facility and during transport of the facility to a disposal site and may be opened to drain the liquid contents from said main compartment at the disposal site.

10. a main compartment having a top, a bottom, fore and aft end walls, and left and right side walls, said walls collectively defining a periphery of said main compartment;

said top having at least one means defining a toilet seat and toilet seat aperture communicating with said main compartment.

2. at least one fore and aft vertical baffle extending between said fore and aft end walls;

3. at least one side to side vertical baffle extending between said left and right side walls;

4. said fore and aft vertical baffle and said side to side vertical baffle joining intermediate their respective to define, in conjunction with said fore and aft end walls and said left and right side walls, a plurality of sub-compartments in said main compartment.
