Abstract

A portable generator unit has a frame, a generator fixed on the frame, a combustion engine fixed on the frame and coupled to the generator to drive it, a fuel tank, and means securing the tank to the frame for pivoting between a use position with the tank overlying and closely juxtaposed with the engine and generator and a maintenance position pivoted up and spaced from and giving access to the engine and generator.

Claims

1. A portable generator unit comprising:

a frame;

a generator fixed on the frame;

a combustion engine fixed on the frame and coupled to the generator to drive it;

a fuel tank; and

means securing the tank to the frame for pivoting between a use position with the tank overlying and closely juxtaposed with the engine and generator and a maintenance position pivoted up and spaced from and giving access to the engine and generator.

2. The portable generator unit defined in claim 1 wherein the means allows separation of the tank from the frame.

3. The portable generator unit defined in claim 1, further comprising

a fuel line connecting the tank to the engine;

and

a quick-connect coupling in the line.

4. The portable generator unit defined in claim 1 wherein the tank is made of a polymer.

5. The portable generator unit defined in claim 1 wherein the frame has polymer side walls.

6. The portable generator unit defined in claim 5 wherein the tank fits complementarily between the side walls in the use position.

7. The portable generator unit defined in claim 5 wherein the generator and engine are largely between the side walls.

8. The portable generator unit defined in claim 1, further comprising

a muffler connected to the engine and underneath the tank in the use position.

9. The portable generator unit defined in claim 1, further comprising

at least two wheels on a lower portion of the frame.

10. The portable generator unit defined in claim 1, further comprising

a handle on an upper portion of the frame.

11. The portable generator unit defined in claim 10 wherein the handle is pivotal on the frame between a rest position closely juxtaposed with the frame and a use position projecting outward from the frame.

12. The portable generator unit defined in claim 1 herein the frame is formed as an assembly of rigid bar-like elements.

13. The portable generator unit defined in claim 1, further comprising:

a muffler connected to the engine and mounted at one end of the frame and

a cover plate at an opposite end of the frame.
