Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arrangement of a tank, a drive body, a transport handle, etc. of a hand-held portable compressor having a tank for storing compressed fluid.

FIG. 1 shows a compressor with a conventional structure. In this structure, a drive section main body 10 consisting of a tank 1, a motor 2, and a drive section 3 is installed vertically to the operating installation surface. , furthermore, the drive unit main body 10
It has a structure in which a cylinder 4 is placed on top of the cylinder. Further, accessory devices such as a pressure gauge 5, a fluid outlet 7, and a safety valve 8 are attached almost randomly around the outer circumference of the tank 1.

On the other hand, the compressor is required to have good stability so as not to fall due to vibrations generated when compressing fluid and vibrations generated by reciprocating movement of a piston (not shown) within the cylinder 4.

In particular, small portable compressors are used by transportation and movement, so they cannot always be used in locations with favorable conditions, and in rare cases, they may have to be installed in unstable locations such as slopes. isn't it.

Therefore, it is desirable to have a compressor with good stability that can be installed with a low center of gravity so that it will not fall over even under these adverse conditions.

However, in the conventional compressor, the tank and the drive unit body are arranged perpendicularly to the operating installation surface, the center of gravity is high, and the spacing between the installation legs is short, resulting in an unstable configuration.

Particularly, in the case of a portable compressor with a small tank capacity, the structure becomes even more unstable, which is a problem.

2 and 3 show a compressor of a prior art construction with a different arrangement from the compressor shown in FIG. It has a structure in which the tank 1 and the drive section main body 10 are mounted on the frame 14 provided, and the legs 12 for installation are provided at the lower part of the frame 14.

This structure has a comparatively lower center of gravity and is somewhat more stable than the structure shown in FIG. The structure was such that the two were perpendicular to each other, making it unstable in terms of weight balance and unsuitable for use as a hand-held portable device.

The object of the present invention is to improve the drawbacks of the prior art mentioned above and to improve the stability of this type of compressor, as well as to facilitate hand-held transportation.

That is, the present invention provides for compressor components such as a tank, a cylinder section, a motor, and a drive section to be arranged vertically on a plane substantially parallel to the installation surface when the portable compressor is installed in an operating state. By shortening and widening the tank, making the center axis of the tank almost parallel to the center axis of the drive body, and connecting them together, the center of gravity in the driving position is lowered and the weight balance is improved. In addition, a hand-held transportation handle is attached to the drive unit body in a position parallel to the drive unit body and opposite to the tank on the plane formed by the motor center axis and the tank center axis. When moving and transporting, it is configured so that it can be transported at an angle of approximately 90 degrees from the direction in which it is installed in the operating state. The aim is to satisfy an advantageous configuration in both aspects during movement.

Hereinafter, the present invention will be specifically explained with reference to illustrated embodiments.

FIG. 4 is a top view showing one embodiment of the present invention, and FIG. 5 is a side view seen from direction A in FIG. 4. In FIG. 4, the center axis EE line of the tank 1 and the center axis FF line of the drive unit body 10 are arranged so as to be substantially parallel, and the cylinder part 4 provided in the drive unit 3 is placed on the tank side. This cylinder part 4
and tank 1 are fixed together with screws 13 to form a connecting means on one end side. Also, the other end side is the stay 15
The motor 2 and the tank 1 are connected with a screw 13 via the screw 13.

The tank 1, motor 2, drive section 3, cylinder section 4, etc. are also arranged on a plane B- which is approximately parallel to the installation plane 9.
They are arranged on the B side and have a thin rectangular shape as a whole, and have a structure that allows an extremely stable posture when installed in the driving position.

Further, a handle 16 for hand-held transportation is attached to the drive unit main body 10 on the opposite side of the tank 1 with the center axis being the B-B plane which is parallel to the central axis E-E of the tank and parallel to the operation installation surface 9. When installed and transported, it is turned approximately 90 degrees from the direction in which it is installed in the operating state, and the motor 2 and tank 1 are connected vertically from above to form a vertically thin trunk shape, making it easy to carry by hand. There is.

Additionally, there is a space 11 between the motor 2 and the tank 1.
A pressure gauge 5, a fluid outlet 7, a safety valve 8, and other attached devices are housed in this space 11, and these easily damaged attached devices are connected to the drive unit main body 10 and the tank 1. It is constructed so that it can be surrounded by a wall to protect it from accidents caused by collisions or falls.

In the portable compressor configured as described above, the vertical dimension L is very short with respect to the operational installation surface, and the distance l from the installation surface of the center of gravity 17 is short. Of these, relatively heavy tank 1
and the drive unit main body 10 are arranged substantially parallel on both sides and are integrally connected and fixed via the cylinder part 4 and the stay 15, and a cylinder part with relatively poor weight balance is created in the space 11 created by the two parts. 4, pressure gauge 5,
Since the structure accommodates accessory equipment such as the fluid outlet 7 and the safety valve 8, the balance in the operating and installation state is very good, and an extremely stable state can be ensured.

In addition, the tank 1 and compressor main body 10 of the attached equipment are protected, so that the attached equipment will not be directly hit if it falls over or falls during transportation, ensuring reliable protection and eliminating the need for special guard members. In addition, the area formed by the tank 1 and the drive unit main body 10 is large, and therefore the distance between the installation legs 12 can be long, resulting in a portable compressor with good stability against vibrations, inclined installation surfaces, etc. It is something. In addition, since the structure of this embodiment has the cylinder part 4 and the tank 1 close to each other, in addition to the above-mentioned advantages, the cylinder part 4
Another advantage is that piping from the tank 1 to the tank 1 is easy.

As described above, according to the present invention, in a compressor equipped with a pressure accumulator tank, the central axis of the tank and the central axis of the drive unit main body are arranged substantially parallel to each other, and a space is formed between them. In addition, the compressor components, such as the tank, cylinder section, and drive unit body, are arranged parallel to the operation installation surface and fixed together, and the handle for hand-held transportation is attached to the drive unit body, and the drive unit body is fixed to the operation installation surface. By arranging the drive unit parallel to the tank center axis and in parallel with the drive unit main body and the tank, the following effects can be achieved.

1 The vertical dimension L is shorter than the operating installation surface,
The center of gravity is located at a low distance from the installation surface, and the relatively heavy tank and drive body are both parallel to each other, connected together and placed on both ends, resulting in good balance during operation and extremely stability. An excellent portable compressor can be realized.

2. By configuring the tank and the drive body to protect accessory equipment that is easily damaged, the conventional guard member can be made unnecessary, and a lightweight and compact portable compressor can be provided.

3 On the bottom of the operation installation, the legs that take the driving position are widely spaced and distributed, and the drive unit body is equipped with a handle for hand-held transportation parallel to the installation surface and the tank center axis, and the drive unit body and tank are mounted in parallel. Therefore, it can withstand vibrations caused by operation, and at the same time, when transporting it, it has to be hung at an angle of 90 degrees from the installed state, so the object is narrow, and the center of gravity of the aircraft The distance between the bodies is shortened, making it easier to move and transport the compressor.
