Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a portable engine generator with optional electrical parts.

<Prior art and its problems> Conventionally, the portable engine generator 4 and the optional electric parts 7 are carried separately,
To attach optional electrical parts 7 such as lamps and battery chargers to the engine generator 4, connect the plug 9 extended from the electrical part 7 to the outlet 6 of the engine generator 4, as shown in Figure 9. was.

However, carrying the engine generator 4 and the electrical parts 7 separately in this way is inconvenient and bulky.

<Example of earlier invention> Therefore, as an example of earlier invention, the present inventor provided an engine 1 and a generator 2 in a case 3 to constitute an engine generator 4, and attached an outlet 6 to a parts mounting surface 5 formed in the case 3. At the same time, a plug 9 is provided on the mounting surface 8 formed on the optional electrical part 7, and the plug 9 is inserted into the outlet 6, so that the engine generator 4 and the optional electrical part 7 can be attached and detached via both mounting surfaces 5 and 8. We considered a structure in which the two fixed outer surfaces 11 and 12 were formed into a continuous surface by being freely fixed.

This allows the engine generator and electrical parts to be carried together, resulting in a smaller overall size.

Hereinafter, an example of the prior invention will be explained based on FIGS. 1 and 2.

Fig. 1 is a perspective view of the engine generator and electric parts separated, and Fig. 2 is a side view of the engine generator with the electric parts attached.The engine generator 4 is a forced air-cooled engine 1 with a recoil starter.
and a generator 2 are housed in a case 3.

The air-cooled engine 1 has a wind guide case 13 in front and a recoil starter 1 in front of it.
4, the cooling air ventilated by the cooling fan housed in the air guide case 13 is guided to the air guide case 13, cools the engine cylinder, and is discharged to the rear.

A rectangular parallelepiped fuel tank 15 is fixed above the generator 2 on the rear left side of the engine 1.

On the other hand, a control panel 16 is installed on the right side wall of the generator 2 to control the generator, and the air-cooled engine 1 and the generator 2 are interlocked and integrated from front to back and then covered with an exterior case 3. A handle 17 is placed above it, and a rubber grounding leg 18 is placed below it.
form each.

A part mounting surface 5 is formed by cutting out the rear right side of the exterior case 3 in the shape of a rectangular parallelepiped, and an outlet 6 is provided on the front wall of the mounting surface, and shrimp metal fittings 10 are attached to each side wall 3a of the front wall. , a locking groove 19 is recessed near the mounting surface of the upper wall.

On the other hand, a mounting surface 8 is formed on the front wall of the box-shaped electrical part 7, a plug 9 is attached to the lower center thereof, a communication groove 20 is provided on both lower side walls, and an L is provided on the upper wall of the front end. letter-shaped hook part 21
and a light portion 7a near the rear of the right side wall.
Equipped with.

In this way, the hook part 21 is fitted into the locking groove 19 provided on the engine generator 4, and the plug 9 is connected to the outlet 6, and the engine generator 4 and the electric parts 7 are connected to each other on the mounting surfaces 5 and 8. Position and fix through. Then, the metal fitting 10 attached to the engine generator 4 is fitted into the connecting groove 20 of the parts part, and the two are firmly fixed.
The outer surface 11 of the outer case and the outer surface 12 of the outer case are formed to be a continuous surface without unevenness.

<Problems with the prior design example> However, in the prior design example, the optional electrical parts cannot be used away from the engine generator while the plug is inserted into the outlet.
Furthermore, even if an electrical part is attached to an outlet other than the outlet on the parts mounting surface, it may not be possible to connect it easily depending on the location of the outlet, which is inconvenient.

The present invention also eliminates the above-mentioned drawbacks of the previous invention, and therefore, the optional electrical parts 7
A plug 9 is removably fixed to a mounting surface 8 formed in the same manner as shown in FIG.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 3 to 8. Note that the explanation of the parts explained in the previous example will be omitted.

As shown in FIG. 3, both the engine generator 4 and the electric part 7 are box-shaped so that their outer surfaces can be connected flush with each other.
A plug 9 attached to the lower center of the mounting surface 8 is detachable so that the cord can be extended long, and a cord winder 22 is formed on the surface opposite to this mounting surface.

In this case, the optional electric parts 7 to be connected and replaced with the engine generator 4 include a light shown in FIG. 5, a battery charger, a speaker with a microphone, and the like.

Next, FIG. 6 shows another embodiment, in which a light 7 is provided with a gripping rod 30 extending from the upper shoulder of the engine generator 4.
A fitting groove 31 is formed in the lower part of the gripping rod 30, and a locking ball 32 is elastically fitted into this fitting groove 31 to fix the light to the engine generator. , and a plug 9 is attached to the lower end of the gripping rod.
is set and connected to an outlet 10 fitted inside the engine generator 4.

Furthermore, if the light 7 is removed from the engine generator 4, the opening of the insertion hole 33 can be closed with the locking door 34, and the light's gripping rod 30 can be closed.
A storage chamber 35 is provided in the center of the storage chamber 35, and by untying the cord wrapped multiple times around the support piece 36 in the storage chamber 35 and pulling out the plug 9 from the lower end of the gripping rod, it is possible to connect to the control panel of the generator. Yes (see Figures 7 and 8).

The effects of the present invention will be described below. Optional electrical parts are detachably connected to the engine generator, and the outer surface of the case composing the engine generator and the outer surface of the electrical parts are formed into a continuous surface without large irregularities. Therefore, by continuously fixing various electrical parts to the engine generator, the appearance can be unified into a smooth surface, creating a beautiful design, and it can also be compacted, making it easier to pack and store. .

In addition, the plug is removably fixed to the mounting surface formed on the electrical part, and the cord that connects to the plug is accommodated in the electrical part in a flexible manner. Not only can it be used away from the generator, but it can also be easily connected to an outlet other than the one on the part mounting surface, making it convenient and expanding its uses.
