Abstract
A portable engine-generator is described having an engine and a generator coupled to the engine. An engine mount has a mounting plate coupled to the engine and also includes a frame. An outer housing surrounds the engine, generator and frame. At least one handle is coupled to the outer housing. The housing is defined in three sections; a lower section, a middle section and an upper section. The three housing sections are coupled to the frame.
Claims48
A portable engine-generator, comprising:
- an engine;
- a generator coupled to the engine;
- an engine mount comprising a mounting plate coupled to the engine;
- an outer housing comprising at least a lower housing base portion and an upper cover portion, the mounting plate being coupled to the lower housing base portion;
- a frame coupled to the lower housing base portion, the frame having vertical portions extending upwardly from the lower housing base portions, and the upper cover portion being coupled to the vertical portions;
- at least one handle coupled to the upper cover portion;
- at least one handle frame coupled to the at least one handle and to the frame;
- and
- the frame is coupled to the at least one handle, the lower housing base portion and the upper cover portion, where the handle and handle frame are coupled to an outside surface of the upper cover portion and the frame is coupled to an inside surface of the upper cover portion;
- wherein the weight load of the engine and generator is supported by the lower housing base portion and the weight load at the handle is reinforced through the frame, the upper cover portion and handle frame.
