Background technique
Mini air compressor has become the general tool around family, workshop and the building site.For family expenses, amusement and other underloading purposes for example gas-filled type motion or amusement equipment or, can supply many very small-sized and light compressors in urgent purposes for automobile tyre inflation.Such operation needs the pressurized air of relatively low pressure and/or low relatively airflow rate.Small-sized by using, low volume and/or by the low pressure compressor of light-weight electric machine power supply keeps very little weight and portability is maximized in these designs.In addition, by omitting high-pressure bottle (that is, fuel tank) and oil lubrication system, acquire the saving of significant weight, size and cost aspect.
Yet, the air pressure that many needs of work are higher, and/or bigger instantaneous airflow requirement, this generally can surpass the ability of interest or the employed compressor of amusement.In order to satisfy the demand of higher air pressure and higher air-flow operation, be necessary to increase the size of compressor and associated motor or motor.In addition, be not the size that strengthens compressor satisfying the instantaneous airflow requirement of theoretical maximum, but the pressurized air storage that holds with air tank or other pressurized container forms is common PRACTICE OF DESIGN.The air tank that output controller is arranged usually, can keep the pressurized air of some to satisfy peak demand from service load, allow simultaneously to use to be full of littler, the lighter compressor of air tank, and can reach the required average compression airflow rate of desired use.
Generally need air tank and bigger compressor to satisfy required pressure and level of air flow, this has increased the weight and the overall dimensions of compressor bank in fact.For the unit of high pressure and high volume job design can reach weight and size rapidly, wherein install or the known motorcycle of breakdown trailer structure is only form of implementation.Still the air compressor that has the intermediate size scale, these compressors are the common tools around the building site and are man-pack.
The current model of man-pack air compressor unit comprises a support or supporting structure, on this supporting structure or motor or motor, air compressor, air tank, gas exhaust manifold and various valve, testing apparatus and controller be installed therein.Many bigger portable construction are equipped with wheel, its so-called trolley structure, and like this, they can be moved by single user.There is the example of the air compressor of wheel to comprise Black﹠amp by DeWalt  brand name; Model D55170 and D55270 that Decker company sells.
Still having some intermediate size professional grade compressor users to find to be necessary or to expect to have can be by portable liter and the compressor that carries.The method commonly used that compressor manufacturing commercialization improves these intermediate size professional grade compressor portability is that the redesign air compressor is to reduce its weight.Although such effort is arranged, the weight of intermediate size professional grade compressor often surpasses 50 pounds, even and therefore concerning those users in vigorous health, by portable liter and mobile still very difficult.
Except the problem of its weight, the heaviness of transporting of portable intermediate size professional grade compressor also is known.About this point, owing to have the mount scheme that compressor and motor are installed, use the structure of two cylindrical shape casees or single flat case (that is, have the major diameter of male end but the cylindrical shape case of low height) to become general.For example, use the structure of two cylindrical shape casees that compressor and motor generally are installed along the case limit, yet use the structure of single flat case generally compressor and motor to be installed in the end of case.
These traditional air compressors are arranged as unit relatively large pedestal or bottom are provided, and center of gravity also is arranged in the approximate centre position of bottom.The air compressor that is arranged as of even now provides metastable structure in its working procedure, often be clumsiness difficulty again but promote and carry the air compressor with this structure.About this point, these structures generally can be used handle (being used for promoting and carrying air compressor), and this handle is connected to the appropriate configuration at the place, center of gravity top position that is vertically mounted on whole air compressor unit, for example on support or the air tank.Handle is generally to need air compressor unit to be promoted vertically upward and to locate in the mode that is carried with the roughly the same direction of its operative orientation.
Yet, it is relative difficult to promote and carry known medium air compressor unit by this way, because the bottom of these air compressor unit trends towards relatively large, and therefore need the user to hold air compressor unit, thereby user's arm is in crooked state with the arm of elongation slightly.In the center of gravity of making great efforts to make compressor bank more in the process near user's central axis, the user generally can tilt its upper body away from the load of air compressor unit, and therefore with uncomfortable and clumsy body gesture lifting and transport air compressor bank.

In the example that provides, horizontal expansion side 32 is configured to open form, and the end 42 of horizontal expansion side like this 32 does not intersect mutually but intersects with air tank 14.End 42 is for example welded with air tank 14 by traditional combination and is combined.In the specific embodiment that illustrates; air tank 14 transversely extends side 32 and extends; but it will be understood to those of skill in the art that thereby air tank 14 can replacedly be configured to stop the flush of horizontal expansion side 32 or the opposite end that inboard supporting structure 16 can also be protected air tank 14.Instrument group 20 generally includes an air tank pressure gauge 46, a regulator 48, a reconciliation statement 50 and an outlet manifold 52, and the instrument group combines with instrument panel 54 between the horizontal expansion side 32 that is installed in supporting structure 16.Instrument panel 54 can be independent parts or can form with cover 38 integral body.Preferably, relative with the vertical substantially orientation shown in the prior art air compressor unit 1 of Fig. 1, instrument panel 54 is installed with sweptback orientation, this illustrates in Fig. 3 and Fig. 4 best, thereby air tank pressure gauge 46, regulator 48, reconciliation statement 50 and outlet manifold 52 is arranged to relative the reading more comfily and/or approaching mode of user of confession air compressor unit 10.Those skilled in the art will learn from disclosed content, the air tank pressure gauge 46 that causes by the location of instrument panel 54 on the orientation that recedes and the improvement of reconciliation statement 50 readability and the improvement of regulator 48 accessibility, improved the accuracy that the user can control the air pressure that is assigned to outlet manifold 52.Selectively be equipped with horizontal expansion side 32 in one combine and outward extending therefrom pin 58, thereby allow part, for example a power line 60 or an air hose 62 twine (around pin 58) in order to deposit.
Mountion plate 34 is expressed as being made by sheet metal, for example steel, aluminium or plastics, and it is as the pedestal 66 of supporting structure 16.Compressor means 12 combines with mountion plate 34 by a plurality of threaded fastener (not shown).A plurality of rubber bottom 68 append on the corner of mountion plate 34 and the vibration that is used for suppressing transmitting by supporting structure 16 and provide a slippery resistance for supporting structure 16.Specifically, form a through hole 70 and allow the user to feed valve system 72 so that manual evacuation of air case 14 by mountion plate 34 with reference to Fig. 6.
Referring again to Fig. 4, it will be understood to those of skill in the art that air tank 14 and compressor means 12 are attached on the supporting structure 16, like this, their center of gravity CG separately ATAnd CG ACBe arranged as relatively more near pedestal 66 (Fig. 3 to Fig. 5) during in air compressor unit 10 towards its working position.Because most of weight of air tank 14 and compressor means 12 duty air compressor groups 10, the structure of this mode is favourable, because it provides low relatively center of gravity CG for air compressor unit 10 ACPIt will be understood to those of skill in the art that center of gravity CG ACPWork in plane 80 along relative pedestal 66 deflections.In the specific embodiment that illustrates, because pedestal 66 is positioned on the plane 82, for example on the ground, plane 80 is vertical substantially with pedestal 66.
With reference to Fig. 3 and Fig. 7, when user 94 transported air compressor unit 10, handle 18 was configured to be held by the palmar aspect 90 of user 94 hand 92.Handle 18 can be any kind and can be installed on any suitable structure, for example on supporting structure 16 or the air tank 14.In the specific embodiment that illustrates, handle 18 is installed on the air tank 14 tightly, and comprises that its profile is the part 96 of holding with a firm grip of accepting user's finger when the user transports air compressor unit 10.The part of holding with a firm grip 96 forms round the center line 98 that is positioned at (maybe can be positioned at) plane 100, and this plane 100 comprises the center of gravity CG of air compressor 10 ACP
Handle 18 allows the user of air compressor unit 10 that air compressor unit 10 is repositioned onto the transporting position shown in Fig. 7 A from working position shown in Figure 4.Reorientate by this way for the ease of air compressor unit 10, available for example traditional threaded fastener (not shown) will protect baffle plate 69 to be fixed on each horizontal expansion side 32 of tubular frame 30.Protection baffle plate 69 preferably is made of the material of the rubber with adhesion characteristics or some other types.In some instances, shown in Fig. 7 B, the user can be rolled to air compressor unit its side.In these examples, protection baffle plate 69 prevents any undesirable user of sliding off of air compressor unit.In the time of in being in transporting position, comprise the center line 98 of handle 18 and the center of gravity CG of air compressor unit 10 ACP Plane 100 be in vertical substantially orientation with user 94 vertical (vertically) axle 104 almost parallels, and be parallel to the pedestal 66 and the top 108 of air compressor unit 10.
In addition, because the center of gravity CG of air compressor unit 10 air compressor unit 10 when being oriented in the working position ACPRelatively more near pedestal 66, user 94 can transport air compressor unit 10, thereby pedestal 66 near user 94 cross side 110 (that is, in about 10 inches of cross side 110, and preferably approximately 3 inches to about 7 inches) and user's wrist 112 not at bent state.When being in transporting position, air compressor unit 10 preferably is configured to make the center of gravity CG of air tank 14 and compressor means 12 ATAnd CG ACBe arranged in plane 100, or relatively be offset the basic distance that equates therefrom.Because handle 18 arranges that like this user 94 can cosily carry air compressor unit 10, and under the situation of release lever 18 not pivot air compressor unit 10 between working position and transporting position easily.
Air compressor unit 10 has so far been described, it comprises air tank 14 with single cylindrical box structure and the secure bond handle 18 to the air tank 14, but it will be understood to those of skill in the art that the present invention can be configured to some difference at it aspect wideer.For example, handle 18a can be incorporated among the supporting structure 16a, as Fig. 8 and shown in Figure 9.In this embodiment, supporting structure 16 extends upward around air tank 14 and from pedestal 66 on the side relative with compressor means 12.Grip structure 96a be formed on the relative interconnective front support rod spare 36a of horizontal expansion side 32a on.As the handle 18 of air compressor unit shown in Figure 3 10, handle 18a arranges that so promptly the center line 98a of grip structure 96a is positioned at the center of gravity CG that comprises air compressor unit 10a when air compressor unit 10a is in transporting position ACPThe plane in.
In the layout of Figure 10, similar among the embodiment of handle 18a and Fig. 8, it combines with supporting structure 16a.Yet air tank 14b comprises first and second substantial cylindrical box structure 150a and the 150b, and relative another of these box structures 150a and 150b piles up vertically when air compressor unit 10b is in the working position.In the layout that illustrates, the first and second substantial cylindrical box structure 150a and 150b are arranged in the opposite side of plane (not specifically illustrating) equidistantly, and this plane comprises center line 98a and the center of gravity CG of handle 18a ACPFirst and second substantial cylindrical box structure 150a that illustrate and 150b separately longitudinal axis 152a and 152b be included in pedestal 66 plane inclined in, therefore reduce center line 98a and the center of gravity CG from comprising handle 18a by the first and second substantial cylindrical box structure 150a and 150b ACPThe amount of planar offset.In this arrangement, mountion plate 34b can improve slightly with respect to the mountion plate 34 of air compressor unit 10, thereby thereby easier and more compactly air tank 14b and compressor means 12a are packed the center line 98a that makes handle 18a and locate in a manner described.
The layout of Figure 11 is similar with Fig. 3 generally, removes handle 18c and is attached to pivotly on the supporting structure 16c at a side place relative with air tank 14.When being positioned transporting position, compressor means 12 is positioned at the top of air tank 14.This layout also shows air compressor unit of the present invention and can rotate along any direction around the rough horizontal axis between work and the transporting position.For example, Fig. 6 and 7 embodiment show the bottom B (or top T) that air compressor unit 10 can forward air compressor unit 10 from the place ahead F of air compressor unit 10 to, and the embodiment of Figure 11 shows the bottom B (or top T) that air compressor unit 10c can forward air compressor unit 10c from the rear R of air compressor unit 10c to.It will be understood to those of skill in the art that the interchangeable bottom (or top) that is configured to forward to by handle 18c air compressor unit of air compressor unit from a side of air compressor unit.
With reference to Figure 12 and 13, another air compressor unit that instruction according to the present invention is constructed is represented by reference character 10d generally.Some is similar for air compressor unit 10d and air compressor unit shown in Figure 3 10, and can comprise a compressor means 12, an air tank 14, a supporting structure 16, one handle 18 and an instrument group 20.Compressor means 12 can comprise few oil or oilless compressor 22d and provide the power source of power, for example motor 24 or motor for oilless compressor 22d.Oilless compressor 22d comprises along axle 302 to-and-fro motion to suck and to compress the piston 300 of ambient air.This paper uses term not have oil and describes an air compressor, the lubricated liquid oils when it does not use oil pan to hold to be used for piston 300 and moves back and forth.Preferably, whole compressor 22d comprises the crankcase (not shown), can work under the liquid lubrication oil condition not having.The pressurized air of discharging from compressor 22d is discharged into air tank 14, and this air tank is as compressed-air actuated storage box.
Air tank 14 can have at least 0.5 gallon capacity, and it is illustrated as having the box structure of single cylinder form in the object lesson that provides.Yet air tank 14 can have about 1 to about 8 gallons capacity, and more preferably has about 3 to about 5 gallons capacity.
Supporting structure 16 can comprise a pair of tubular support 30d and mountion plate 34d.Mountion plate 34d can comprise a base assembly 310 and can be incorporated into and from base assembly 310 outward extending offside assemblies 312.With reference to Figure 14, each side assembly 312 can comprise arc end face 314 in addition, and this arc end face 314 is configured in abutting connection with the part of the periphery of air tank 14, and this moment, base assembly 310 was against air tank 14.Although base assembly 310 can be in any position in the lower quadrant 320 of air tank against air tank 14, but the upper surface 322 of base assembly 310 can be arranged like this, cause it and first plane, 324 almost parallels, this first plane 324 is by air tank 14 longitudinal extensions and divide air tank 14 equally, and the edge 326 of base assembly 310 terminates in the point that is included in second plane 328, this second plane 328 and first plane, 324 approximate vertical and by air tank 14 longitudinal extensions and divide air tank 14 equally.Structure by this way is with the center of gravity of air tank 14 (CG for example AT) orientate as relatively more near base assembly 310, and prevent that air tank 14 from extending below mountion plate 34a.It will be understood to those of skill in the art that, edge 326 can not be implemented on the basis of mass production reliably with accurately aliging of plane 328, and therefore be appreciated that the purpose of disclosed content and claims is, skew between edge 326 and plane 328 is less than or equal to 0.25 inch (promptly, on the either side on plane 328 0.25 inch) time, edge 326 is arranged in plane 328.
First end of tubular support 30d can be incorporated on the base assembly 310, and tubular support 30d second opposed end can be incorporated on the air tank 14.Therefore tubular support 30d is located on the opposite side of compressor means 12, thereby protects compressor means 12 air compressor unit 10d not overthrown by other object or impact.
In the example that provides, can detachably be attached on supporting structure 16 and/or the compressor means 12 by the guard shield 330 that sheet metal or plastics are made.Although the main purpose of guard shield 330 is to be used for the guard block for example instrument that for example falls that is not in contact with it of compressor means 12 and instrument group 20 and the infringement of workpiece; but it will be understood to those of skill in the art that; compare with the other parts of air compressor unit 10d; if against user's cross side, the relative smooth exterior surface face of guard shield 330 is more comfortable relatively and less interfere user's motion so in the process of transporting.
Instrument group 20 generally includes an air tank pressure gauge (not shown), a regulator (not shown), a reconciliation statement (not shown) and an outlet manifold 52, and the instrument group can be installed to any easily on, for example be installed on air tank 14, supporting structure 16 or the compressor 22d.
