Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a generator that is small and convenient to carry.

(Conventional technology) Conventionally, the entire body was covered with three points: the bottom cover, the front cover and the rear cover that constituted the top cover, and the rear cover was detachably separated from the front cover at the side, and the rear cover was made of synthetic resin. A portable generator made by
59-170596).

(Problems to be Solved by the Invention) The conventional portable generator has the following problems.

(b) The mounting opening of the rear cover has a three-dimensional shape, and the rear cover is separated from the front cover at the side so that it can be attached and detached, making it difficult to attach and detach.
In addition, the cost of the fixture increases.

(b) The required strength of the entire portable generator (the strength required assuming that heavy objects will be placed on top) must be ensured only by the front cover, but as mentioned above, the front cover must be placed at the rear. Due to the large opening, it is difficult to make this from synthetic resin.

(Means for Solving the Problems) A portable generator according to the present invention includes a bottom cover having a flange portion around the entire periphery, and a bottom cover that is fastened to the flange portion and is divided at the maximum width portion approximately in the center of the side and top surfaces. It has a front cover and a middle cover each having a half-split handle at the top, and forms a bag shape with a planar opening at the rear at the three points above, and can be opened and closed at the opening. Attach a flexible rear cover, install the engine and the generator driven by the engine on the bottom cover, collect the operating system in front of the front cover, and collect maintenance-required parts at the rear and open the It is characterized by having been made to appear.

(Function) In the present invention, the rear cover can be opened and closed freely, and the ratio of the rear cover to the entire portable generator is small, so that maintenance is sufficiently facilitated.

(Example) Hereinafter, one example of the present invention will be described based on the drawings.

Fig. 1 is a central vertical sectional side view of this embodiment, Fig. 2 is a central vertical sectional side view showing only the cover, Fig. 3 is a front view showing the external appearance of the embodiment, and Fig. 4 is a side view of the same. FIG. 5 is a rear view of the same, and FIG. 6 is a rear view with the rear cover removed.

The portable generator 1 includes a bottom cover 2 made of sheet metal, a front cover 3 made of synthetic resin, a middle cover 4, and a rear cover 5 as covers that cover the entirety.

Among the covers, the entire periphery of the bottom cover 2 is designed to form a bag shape with a planar opening at the rear at three points: the bottom cover 2, the front cover 3 covering the top, and the middle cover 4. The front cover 3 and the inner cover 4 are fastened to the flange portion 2a provided on the front cover 3 with screws 6, and are also connected to each other by means such as adhesion or welding.

The rear cover 5 covers the bag-shaped rear opening 7 and is supported by the inner cover 4 so as to be openable and closable by means of a hinge mechanism 8 at the lower part and a mounting screw 9 at the upper part.

Note that leg portions 10 made of anti-vibration rubber are provided on the lower surface of the bottom cover 2.

Further, the front cover 3 and the middle cover 4 are divided at the maximum width portions approximately at the center of the side and top surfaces of the portable generator 1, and halved handle portions 3a and 4b are protruded from the upper portions thereof. At the same time, the part is fastened by the mounting screw 11 to the handle 1.
2 is formed.

On the bottom cover 2, an engine consisting of an engine body 14 (cylinder part 14a, crankcase part 14b), etc. is directly connected to the rotor drive shaft of the generator body 15 via a vibration-proof rubber 13. (See Figure 6).

On the front surface of the front cover 3, there are assembled an operation system, that is, an operation panel 20 equipped with a voltmeter 16, an ammeter 17, a pilot lamp/stop button 18, a circuit breaker 19, and an output socket panel 22 equipped with an output socket 21. It is being
(See Figures 1 and 3).

Maintenance-required parts in the portable generator 1, namely, the fuel filter 23 and the carburetor 2
4. The air cleaner 25, oil plug 26, and tappet clearance inspection cover 27 are gathered at the rear and are exposed to the opening 7 (see Figures 1 and 6).
(see figure).

In addition, in FIG. 3, 28 is a recoil starter handle, and in FIGS. 5 and 6, 28 is a recoil starter handle.
9 is a fuel tank cap, 30 is a spark plug cover, 31 is an intake port, 32 is an exhaust port, 33 is a fuel tank, 34 is a recoil starter, 35 is a cooling air intake hole, 36 is a cooling fan part, 37 is a rubber etc. The exhaust duct is made of a flexible material, 38 is a muffler, and 39 is a muffler tail pipe.

In this embodiment, first, the bottom cover 2, the front cover 3, and the middle cover 4 form a bag shape with a part of the rear open planarly, so that the rear cover 5 occupies a small proportion of the whole. And rear cover installation port 7
is two-dimensional, and the rear cover 5 can be easily opened and closed by simply attaching and detaching one mounting screw 9.

Also. Parts requiring maintenance are collected at the rear.
Since it faces the opening 7, parts requiring maintenance are exposed simply by opening the rear cover 5, which is very advantageous in terms of maintenance.

Further, even if a heavy object is placed on the portable generator 1, the weight is dispersed in the bag shape formed by the front cover 3 and the middle cover 4, and the heavy object is efficiently supported.

Therefore, front cover 3, middle cover 4, rear cover 5
Even if it is made entirely of synthetic resin, it is possible to secure the necessary strength, and by covering the entire area around the engine body 14, generator body 15, etc. with a synthetic resin cover, it is very advantageous in terms of heat insulation and sound insulation. .

(Effects of the Invention) According to the present invention, (i) The mounting opening of the rear cover is two-dimensional, and the ratio of the rear cover to the whole is small, so that force is not applied to the rear cover during product handling such as transportation. Since the rear cover can be opened and closed with a simple mechanism, the cost of mounting tools can be reduced.

(ii) Since the bottom cover, front cover, and middle cover form a bag shape with a planar opening at the rear, the required strength can be ensured even if the front cover and middle cover are made of synthetic resin. In addition, since the handle is formed by a half-split handle portion at the top of each of the front cover and the rear cover, the load acting on the handle during transportation is distributed to each cover.

Therefore, the front cover, middle cover, and rear cover can all be made of synthetic resin, which is advantageous for weight reduction, cost reduction, heat insulation, and sound insulation.

(iii) Maintenance of the fuel filter, carburetor, etc. can be performed immediately by simply opening the rear cover.

(iv) Since the front cover and the rear cover are fastened to the flange portion around the bottom cover, their holding strength can be improved.

This excellent effect can be obtained.
