Abstract

Claims (26)

1. A dolly and compressor assembly comprising:

a frame having at least one handle structure and a support portion;

at least one wheel attached to said frame;

a platform supported by said support portion and having a retention formation disposed on a generally planar, level platform surface; and

a compressor having an air tank and a receptor structure disposed on a bottom portion of said air tank, said receptor structure configured for engaging said retention formation;

wherein said platform has a hole, and said air tank has a boss with a receiving hole, wherein said boss and receiving hole are configured to receive a threaded fastener inserted through said hole of said platform.

2. The dolly and compressor assembly of claim 1 wherein said retention formation further comprises at least one lug.

3. The dolly and compressor assembly of claim 2 wherein said at least one lug extends from said generally planar, level platform surface and is configured for detachably engaging said receptor structure.

4. The dolly and compressor assembly of claim 1 wherein said receptor structure further comprises at least one leg.

5. The dolly and compressor assembly of claim 4 wherein said at least one leg further includes a hole being sized to mechanically accommodate said retention formation, which is aligned with said hole.

6. The dolly and compressor assembly of claim 1 further including at least one isolator.

7. The dolly and compressor assembly of claim 6 wherein said at least one isolator is disposed between said receptor structure and said platform.

8. A dolly for use with a compressor including an air tank, said air tank having a bottom portion and a receptor structure disposed on said bottom portion, comprising:

a frame having a handle structure and a support portion;

at least one wheel attached to said frame; and

a platform supported by said support portion and having a retention formation disposed on a generally planar, level platform surface, said retention formation having a plurality of lugs in a spaced arrangement and configured for detachably engaging the receptor structure disposed at the bottom portion of the air tank;

wherein said retention formation includes a hole disposed in said platform and located generally at the center of said arrangement of lugs.

9. The dolly of claim 8 wherein said support portion and said handle structure are generally perpendicular to each other.

10. The dolly of claim 8 wherein said lugs are disposed on said generally planar, level platform surface for matingly engaging a plurality of holes disposed on the receptor structure.

11. A compressor for use with a dolly having a frame, at least one wheel attached to said frame, a platform supported by said frame, and a retention formation associated with said platform comprising:

an air tank having a bottom portion;

at least one leg attached to said air tank and extending beneath said bottom portion of said air tank; and

a receptor structure disposed on said at least one leg and configured for engaging the retention formation;

wherein said receptor structure further comprises a boss with a receiving hole disposed on said bottom portion of said air tank, said receiving hole being threaded.

12. The compressor of claim 11 wherein said at least one leg further comprises a hole sized to mechanically accommodate the retention formation, which is aligned with said hole.

13. The compressor of claim 11 wherein said receptor structure further comprises at least one isolator located on a bottom surface of said at least one leg.
