Abstract

A portable toilet is provided comprising a bowl provided with an outlet and at least one spout. A flush tank is adapted to store a fluid, wherein the flush tank is adapted to be pressurized. A manually-actuated pump is in sealed communication with the flush tank, wherein the pump is adapted to cause the flush tank to become pressurized. A pressure relief valve adapted to release pressure from the flush tank. A manually-actuated flush valve is in sealed communication with the flush tank and is normally biased to a closed position. The flush valve includes a fluid outlet connected to the at least one spout and a fluid inlet. A flush valve actuator is disposed outside of the flush tank and is adapted to actuate the flush valve, wherein actuation of the flush valve actuator causes the flush valve to open to permit pressurized fluid contained within the flush tank to be delivered through the at least one spout.

Claims (33)

1. A portable toilet, comprising:

a bowl provided with an outlet and at least one spout;

a flush tank adapted to store a fluid, wherein the flush tank is adapted to be pressurized;

a manually-actuated pump in sealed communication with the flush tank, wherein the pump is adapted to cause the flush tank to become pressurized;

a pressure relief device adapted to release pressure from the flush tank;

a manually-actuated flush valve in sealed communication with the flush tank and normally biased to a closed position, including a fluid outlet connected to the at least one spout and a fluid inlet; and

a flush valve actuator disposed outside of the flush tank and adapted to actuate the flush valve,

wherein actuation of the flush valve actuator causes the flush valve to open to permit pressurized fluid contained within the flush tank to be delivered through the at least one spout.

2. The portable toilet as provided in claim 1 , wherein the at least one spout comprises two spouts.

3. The portable toilet as provided in claim 2 , wherein the two spouts are configured to dispense the fluid in opposite directions.

4. The portable toilet as provided in claim 1 , wherein the pressure relief device is configured to automatically relieve pressure from the flush tank above a predetermined amount.

5. The portable toilet as provided in claim 4 , wherein the pressure relief device is capable of being manually-actuated to relieve pressure from the flush tank.

6. The portable toilet as provided in claim 4 , wherein the flush tank includes a fill tube adapted to receive the fluid and a fill cap in sealed communication with the fill tube and flush tank, wherein the fill cap includes the pressure relief device.

7. The portable toilet as provided in claim 1 , wherein the pump is adapted to pump a compressible fluid into the flush tank to thereby cause the flush tank to become pressurized.

8. The portable toilet as provided in claim 1 , wherein the fluid inlet is disposed towards the bottom of the flush tank.

9. A portable toilet, comprising:

a portable upper section including a bowl;

a flush tank adapted to store a fluid;

a seat assembly including a seat and a lid adapted to cover the seat; and

a first hinge adapted to pivotally attach the lid to the upper section, wherein the lid is adapted to be removed from the upper section when the first hinge is pivoted to a predetermined angle relative to the upper section,

manually-actuated pump in sealed communication with the flush tank, wherein the pump is adapted to cause the flush tank to become pressurized, and wherein the lid further comprises at least one aperture adapted to permit a portion of the manually-actuated pump to extend through the lid.

10. The portable toilet as provided in claim 9 , wherein the first hinge is substantially U-shaped.

11. The portable toilet as provided in claim 9 , further comprising a second hinge adapted to pivotally attach the seat to the upper section.

12. The portable toilet as provided in claim 11 , wherein the seat is adapted to be removed from the upper section when the second hinge is pivoted to a predetermined angle relative to the upper section.

13. The portable toilet as provided in claim 12 , wherein the second hinge is substantially U-shaped.

14. The portable toilet as provided in claim 12 , where in the lid and the seat are each adapted to be removed from the upper section when the first hinge and the second hinge are pivoted approximately 180° relative to the upper section.

15. The portable toilet as provided in claim 9 , wherein the seat further comprises at least one aperture adapted to permit a portion of the manually-actuated pump to extend through the seat.

16. A portable toilet, comprising:

a portable upper section including a bowl;

a flush tank adapted to store a fluid;

a seat assembly including a seat and a lid adapted to cover the seat; and

a first hinge adapted to pivotally attach the lid to the upper section, wherein the lid is adapted to be removed from the upper section when the first hinge is pivoted to a predetermined angle relative to the upper section,

wherein the seat is formed with the upper section.
