Similarly, the brackets 24, 25 of the air tank 10
In addition to the structure shown in FIG. 8, the connecting structure between the connecting members 11 and 12 is made by forming the connecting members 11 and 12 with a material such as resin having appropriate elasticity, as shown in FIG. Only the coupling member 11 and the bracket 24 side are shown), the bushes 19 and 20 are omitted, and the coupling members 11 and 12 and the bracket are omitted.
Alternatively, the bolts 18 and 24 may be directly brought into contact with each other and connected by the bolt 18.

As shown in FIG. 2, the coupling members 11 and 12 have lengths L on both sides thereof which are substantially equal to or slightly smaller than the diameter D of the air tank 9 and the cylinder portion of the compressor body 9.
It is larger than the height H including 13. Coupling member 1
Non-slip grips 11a and 12a are provided at the center of 1 and 12
Is provided. Further, the coupling members 11 and 12 are the grips 1
Both side portions are projected from the central portion where 1a and 12a are provided, and as shown in FIGS. 4 and 5, the connecting member 11 or
When the air compressor 8 is placed vertically so that the 12 is grounded, the grips 11a and 12a are not grounded.

The operation of the first embodiment constructed as above will be described below.

The compressed air body 9, the air tank 10 and the connecting members 11 and 12 are integrally connected to form a strong frame structure. The cylinder portion 13 of the compressed air main body 9 is arranged so as to be inclined toward the air tank 9, and the diameter D of the air tank 9 and the length L of both sides of the connecting members 11 and 12 are greater than the height H of the compressed air main body 9. Since the compressed air main body 9 is also protected by the strong air tank 10 and the coupling members 11 and 12, the compressed air main body 9 is provided around the compressed air main body 9 and its surroundings against an external impact such as a fall. It is possible to protect auxiliary equipment (not shown).

For example, as shown in FIG. 2, when a flat plate 28 (or a part of a cover covering the air compressor 8) is provided on the upper portion of the air compressor 8 and a heavy object W is placed thereon,
Since 28 is supported by the air tank 10 and the connecting members 11 and 12 and no load is applied to the auxiliary machines and the like around the compressor body 9, a heavy object can be placed on the air compressor 8.

Further, the air compressor 8 has a structure as shown in FIG.
As shown in, the connecting member 11 or 12 can be vertically installed so that it is grounded. In this case, the connecting member 11,
Since both sides of 12 are projected from the central part where the grip parts 11a and 12a are provided, even if the ground is uneven, it can be stably placed vertically. In this case also, the connecting member
When a flat plate 28 (or a part of a cover that covers the air compressor 8) is provided on the upper part of 11 or 12 and a heavy object W is placed on it (illustrated only in FIG. 4), the flat plate 28 is joined. Member 1
Since a load is not applied to the auxiliary equipment etc. around the compressor body 9 supported by the air tank 10 and the compressor body 9 via 1 and 12, place a heavy object on the air compressor 8. You can

Further, the air compressor 8 can be carried by gripping the grip portions 11a and 11b of the coupling members 11 and 12. At this time, one or both of the grip portions 11a and 11b can be gripped and can be lifted from various directions, which is very convenient for carrying.

Since the air compressor body 9 and the air tank 10 and the connecting members 11 and 12 are connected via the bushes 19 and 20 made of an elastic material such as rubber as shown in FIGS. The vibration of the compressor body 9 during operation is caused by the bushes 19 and 20.
Is less likely to be transmitted to the air tank 10 and the ground, and noise due to vibration can be reduced. Also,
Even if the coupling members 11 and 12 are made of a material having appropriate elasticity as shown in FIGS. 9 to 11, the vibration of the compressor body 9 is damped by the coupling members 11 and 12.
Noise caused by vibration can be reduced in the same manner as described above.

Next, a second embodiment of the invention will be described with reference to FIGS. The second embodiment is different from the first embodiment in that the compressor body 9 and the connecting members 11 and 12 are connected.
Since they have generally the same structure except that the connecting portions of are different, the same members as those of the first embodiment will be denoted by the same reference numerals and only different portions will be described in detail below.

As shown in FIG. 12, in the air compressor 29 of the second embodiment, brackets 30 and 31 are projected from between both end portions on one side of the connecting members 11 and 12. The tip ends of the mounting legs 16 and 17 extending from the brackets 30 and 31 are joined to the mounting bosses 14 and 15 of the compressor body 9. With this configuration, the same operation and effect as those of the first embodiment can be obtained.

Further, in the one shown in FIG. 13, the air compressor 29
A cover 32 is attached to cover the compressor body 9.
The cover 32 is an upper cover 32 that covers the upper portion of the compressor body 9.
It is composed of a and a lower cover 32b covering the lower part, and these are attached to the air tank 10 and the connecting members 11 and 12 to be integrated. In this case, the cover 32 is supported by the air tank 10 and the connecting members 11 and 12, and the cover 32
Even if the heavy object W is placed on the air compressor 29, a heavy load can be placed on the air compressor 29 because no load is applied to the auxiliary machines and the like around the compressor body 9.

Next, an example of the compressor body 9 applicable to the embodiment of the present invention will be described with reference to FIGS. 14 to 16. It should be noted that portions corresponding to the respective portions of the compressor body 9 of the first and second embodiments will be described with the same numbers.

As shown in FIGS. 14 to 16, brackets 33 and 34 are attached to the outer peripheral portions of both ends of the compressor body 9, and the mounting bosses 1 are attached to the brackets 33 and 34, respectively.
4, 15 are formed. The mounting bosses 14 and 15 are arranged so as to be inclined with respect to the cylinder portion 13. With this configuration,
The compressor body 9 is connected to the connecting member 1 via the brackets 33 and 34.
The cylinder portion 13 of the compressor body 9 is fixed to the air tank 10 side while being connected to the air conditioner 1 and 12.

[0030]

As described above in detail, in the air compressor of the present invention, the compressor main body and the air tank are arranged in parallel, and the substantially H-shaped coupling members are arranged at both ends of the compressor body and the air tank. Since the main body and the air tank are connected to the connecting member to be integrated, the compressor main body, the air tank and the connecting member are integrated to form a strong frame structure, and the air tank and the substantially H-shaped connecting member are formed. The compressor body is protected by this, and the central portion of the coupling member can be gripped and lifted. As a result, the compressor body can be surely protected and easily carried. Furthermore, by connecting the compressor body and the air tank via an elastic body, the vibration of the compressor body during operation is attenuated by the elastic body and is less likely to be transmitted to the air tank and the ground, so noise due to vibration is reduced. can do.
