Abstract

Mounts can be provided at the four corners of a bottom portion of an engine generator. Projections for mounting handles can be provided at a top portion of the engine generator in vertical alignment above the mounts. The bottom face of each mount can be formed with a fitting groove having an open end. Fitting the projections in the fitting grooves allows stacking plural engine generators. The mount can be constituted with a bottom portion, a side portion, and a reinforcing metal fitting. The projections can be disposed on a front frame and a rear frame, respectively, each formed in one body. The mounts can also be attached to the front frame and the rear frame.

Claims

1. An engine generator comprising a handle disposed at a top portion of the engine generator configured to allow a user to carry the engine generator by the handle, a mount positioned at a bottom portion of the engine generator for supporting the engine generator, and a handle assembly comprising a handle mounting portion and the handle, the handle mounting portion being configured to mount the handle to the engine generator, the handle being disposed at the top portion of the engine generator in a generally vertical alignment above the mount, wherein the mount is shaped and oriented to engage the handle assembly if the handle assembly were disposed on another engine generator disposed below the mount, so as to allow stacking plural engine generators, wherein a bottom face of the mount is formed with a recess, in which the handle mounting portion can be fitted to allow stacking the plural engine generators.

2. The engine generator according to claim 1, wherein part of a peripheral wall portion defining the recess is cut to form an open portion.

3. The engine generator according to claim 2, wherein the mount is disposed along a corner formed by the bottom face and the side face of the engine generator.

4. The engine generator according to claim 1, wherein the top face of the handle mounting portion is formed with a recess, in which the mount is fitted to allow stacking the plural engine generators.

5. The engine generator according to claim 4, wherein the mount is disposed along a corner formed by the bottom face and the side face of the engine generator.

6. The engine generator according to claim 1, wherein the mount is disposed along a corner formed by the bottom face and the side face of the engine generator.

7. The engine generator according to claim 6 further comprising a support member formed in one body and extending from the bottom portion to the top portion of the engine generator, the support member being provided with the mount and the handle mounting portion.

8. The engine generator according to claim 7, wherein the mount is provided with a reinforcing member.

9. The engine generator according to claim 6, wherein the mount is provided with a reinforcing member.

10. The engine generator according to claim 1 further comprising a support member formed in one body and extending from the bottom portion to the top portion of the engine generator, the support member being provided with the mount and the handle mounting portion.

11. The engine generator according to claim 1, wherein the mount is provided with a reinforcing member.
