Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a novel handle arrangement for a portable air compressor unit. More particularly, the present invention relates to a novel arrangement of semi-rigid piping around the body of a portable air compressor unit to form a handle arrangement that allows the unit to be easily carried. More particularly, the present invention forms a handle arrangement and conveniently provides suction, fill and discharge connections for engagement with a hose fitting (within the main body of an air compressor unit). Concerning the new arrangement of the surrounding piping system.

The prior art includes a wealth of lightweight, standard refrigerator compressors, most of which are designed to be mounted on stationary paces.

Even when portable units were disclosed as described in U.S. Pat. , and were often bulky means.

SUMMARY OF THE INVENTION It is, therefore, a primary object of the present invention to provide a novel handle arrangement that can be attached to and useful for transporting certain air compressor units.

Another object of the invention is to provide a handle device having a novel configuration that incorporates compressor vacuum evacuation and filling functions therein.

Yet another object of the invention is to provide a handle apparatus for carrying a compressor that is inexpensive, simple in design, and easy to install on many standard compressors with little modification. It is.

These and other objects of the invention will be better understood upon consideration of the following detailed description in conjunction with the accompanying drawings, which reflect the invention exactly as described in the drawings. It will also be understood that the invention is not limited to, and that changes and modifications may be made without materially departing from the patent of the invention as expressed in the following claims.

As illustrated in FIGS. 1 and 2, the tubular handle device of the present invention and a standard refrigerator compressor are shown in an engaged position. Such illustrations are helpful in depicting the utility of the invention and are convenient for understanding the operation and function of the invention disclosed herein.

10 generally indicates a standard refrigerator compressor.

The suction connection of this compressor is designated 12. In forming the novel and useful handle device of the present invention, the piping 11 having a certain length is a standard refrigerator compressor 1.
It is appropriately connected to the suction outlet 12 of 0. The suction outlet 12 is connected to the split well 2 of the compressor 10 on the side of the compressor 10 depicted as side A near the rightmost end of the compressor 10.
0 (Figure 2). This pipe connected to the suction outlet 12 runs counterclockwise along the lower part of the A side towards the gutter and upwards. This pipe also runs laterally around the B side and Extending upwards, the suction connection 12 on the A side has also been rotated 180° until it reaches a point directly below the split well 20 near the farthest end of the B side. From the C side, this piping extends laterally below the split well 20. From the C side, this piping extends laterally to the D side, about 5 clIL above the top of the compressor on the D side. The suction outlet line 11 then makes a 160° turn, horizontally pointing the center of the compressor 10 down the length of the compressor. across and over the B-side suction outflow piping (encircled by
It extends to a terminal end extending approximately 3 inches beyond the body of the compressor 100.

A valve core fitting 13 is attached to the terminal end of the suction/outflow pipe 11, and a suitable hose connection part can be engaged with the fitting 13 as appropriate.

The discharge outlet of the compressor (22) 10 is indicated at 14 (FIG. 1). This outlet is located directly below the suction outlet connection 12 on the main body of the compressor unit 100. The piping 15 appropriately connected to the discharge inlet 14 runs laterally along the A side until it reaches about half way around the B side.
Moreover, it extends upward. When I reached there,
It now extends upwardly toward the top of the compressor unit 10 until it reaches a point approximately 5 cm (2 inches) above the top of the compressor. The line 15 then runs across the center of the compressor unit and along the entire length of the compressor, parallel to but on the far side of the line 11 attached to the suction outlet 12, the main body of the compressor unit 100 about 7. 6cIrL
(3 inches) and extends horizontally until it terminates (Figure 2).

As with the pipe 11, the end of the pipe 15 is fitted with suitable adapter means 16.

The oil drain port 18 is also disposed on the A side of the compressor unit 10 at an end that is also away from the suction outlet 12 and the discharge outlet 14 . The oil drain port 18 of the compressor unit 10 is
Pipes 19 extending clockwise from the A side of the compressor unit 10, laterally along the D side, and upward are connected as appropriate.

Near the halfway point on the D side, the line 19 turns upward toward the top of the compressor unit until it reaches about 5 cIrL (2 inches) above the top of the compressor knit.

There, the line 19 is turned at an angle of about 160'' and runs across the center of the compressor unit, parallel to and between the suction line 11 and the discharge line 15 over the entire length of the compressor. It extends horizontally until it reaches a point near the outer periphery of the main body.

A +T" joint 23 is attached to the pipe 19 near the oil drain port 18. It is for discharging oil from the TI vertical joint compressor unit. The remaining portion of the line 19 located after the 'T' fitting serves no special function other than providing additional support for the handle uniquely formed by the suction line 11 and the discharge line 15.

As shown in FIGS. 1 and 2, the oil drain 18 is located with a Tl fitting and a portion of the pipe 19. However, the drain 18 is completely plugged and the pipe 19 is It is also conceivable to attach the oil drain port 18 to the plugged oil drain port 18 to form a handle without including the TI vertical joint. In such a case, the compressor unit 10 may have an oil drain port located somewhere else, such as A of the compressor unit 10.
It may be modified to be placed on the side below the suction and discharge outlets.

After the piping has been placed around the compressor unit as described herein, the piping is optionally secured by suitable means, such as by welding or the like.

The handle device of the present invention not only attaches to a standard lightweight refrigerator compressor, but can also be used to inflate vehicle tires or supply compressed air if a suitable fitting is connected to the discharge pipe adapter 16. It can be used for any other purpose you need.

Alternatively, when properly engaged, the suction piping line 11 can act as a vacuum pump to evacuate air or other non-water fluids from automotive, domestic or commercial near conditioners and refrigerators.

The novel handle device disclosed herein is constructed from semi-rigid metal tubing, such as steel tubing, of suitable dimensions and strength;
Preferably, the handle arrangement is such that it can easily support the weight of the compressor unit without causing deformation that could lead to damage during transportation.

The handle apparatus disclosed herein is generally compatible with standard lightweight, off-the-shelf refrigerator compressors. These standard refrigerator compressors come in /horsepower, /horsepower, and/or subhorsepower varieties and are manufactured by a number of manufacturers. The illustrated compressor (second
Although Figure 1) is depicted as having a round shape, the nodule means can also be used with rectangular shaped compressors, so the disclosure herein is limited to round shaped compressors only. Never.

It is to be understood that the invention is not to be construed as limited to the accompanying drawings and specification. Although particular embodiments of the invention have been illustrated and described herein, it is not intended that the invention be limited to what is so disclosed, and that additional changes and modifications may be made thereto. can.
