Description
- The present invention relates to air compressors and, more particularly, to portable air compressors.
- Conventional portable air compressors include a movable structure fixed to the air compressor having a multiple wheels and supports that allows a user to easily transfer the entire air compressor around a worksite. However, an air compressor is used with a wide range of pneumatic tools and the location around a worksite can change dramatically depending on the pneumatic tool used. For example, a pneumatic nail gun used on a rooftop and a pneumatic paint spray gun used in a lower level of a house are presented with completely different space limitations.
- In current portable air compressors, all or most components (e.g., air tank(s), pump, frame, etc.) are typically fixed together as one air compressor unit. This causes the air compressor to be cumbersome and difficult to move around the worksite. It is advantageous to position the air compressor proximate to the worksite to minimize pressure loss as a result of excess air hose line connecting an air storage tank to the pneumatic tool. Therefore, returning to the example, the user must position the air compressor near the roof top to optimally use the pneumatic nail gun, and the user must transport the air compressor throughout floor levels to optimally use the pneumatic paint spray gun.
- In one aspect, the invention provides a portable air compressor assembly. The portable air compressor assembly includes a compressor component unit and a tank unit removably coupled to the compressor component unit. The compressor component unit includes a prime mover, a pump operably coupled to the prime mover, and a first tank fluidly connected to the pump to receive pressurized air from the pump when operated by the prime mover. The tank unit includes a second tank fluidly connected to the pump to receive pressurized air, and a manifold assembly fluidly and mechanically coupled to the second tank such that the second tank and the manifold assembly are removable from the compressor component unit together.
- In another aspect, the invention provides a portable air tank unit. The portable air tank unit includes an air tank for storing compressed air, an inlet fluidly coupled to the air tank, a quick-disconnect fitting fluidly coupled to the inlet, an outlet fluidly coupled to the air tank, and a manifold assembly fixedly coupled to the air tank and fluidly coupled to the outlet of the air tank. The manifold assembly includes a pressure gauge operably coupled to the air tank for displaying a pressure of the compressed air in the air tank, and a pressure regulator for regulating a supply pressure of air released from the air tank.

FIG. 1 illustrates a portableair compressor assembly 10 according to one construction of the invention. The portableair compressor assembly 10 includescompressor component unit 12, atank unit 14, and arigid structure 16 that houses thecompressor unit 12 and the tank unit 14 (FIG. 8 ). Thecompressor component unit 12 includes aprime mover 18, apump 20, and a first orfixed air tank 22. In the illustrated construction, theprime mover 18 is an internal combustion engine, such as a four-stroke engine. In other constructions, other prime movers may be employed, such as motors, specifically electric motors, other internal combustions engines, turbines, etc. Theprime mover 18 provides rotary power and is positioned adjacent to thepump 20. In the illustrated construction, thepump 20 is an air compressor pump that provides a pressurized airflow as a result of rotational movement of apump flywheel 24. In other constructions, other types of air compressor pumps may be employed. Theprime mover 18 and thepump flywheel 24 are aligned such that theprime mover 18 is rotationally coupled to thepump flywheel 24 by a drive belt (not shown). - The
rigid structure 16 includes aframe 26,wheels 28, andsupport members 30. Theframe 26 is preferably constructed from a tubular metallic material able to provide sufficient strength and rigidity to therigid structure 16. In other constructions, theframe 26 may be constructed from other suitable materials, such as polymeric or ceramic material and may be tubular, non-tubular, solid, hollow, etc. Thewheels 28 are rotationally coupled to theframe 26 by anaxle 32 defining a rotational axis A (FIG. 2 ). In the illustrated construction, two wheels are employed. In other constructions, one wheel may be employed (e.g., a wheelbarrow-style compressor), or three or more wheels may be employed. Theframe 26 is in contact with a support surface or support plane 34 (e.g., the ground) (FIG. 5 ) via thewheels 28 and thesupport members 30 that are coupled to theframe 26 and positioned at a distance from thewheels 28. Thewheels 28 are disposed near afirst end 36 of theframe 26, and thesupport members 30 are disposed near asecond end 38 of the frame generally opposite thefirst end 36. Thewheels 28 and thesupport members 30 are tangentially aligned substantially in a plane, e.g., thesupport plane 34. - The
rigid structure 16 also includes arotatable handle member 40 fixed to at least twobrackets rotatable handle member 40 having a substantiallyelongated section 46 transitioning into abent section 48 defining atransport handle 50. The substantiallyelongated section 46 extends generally in a direction between the first andsecond ends frame 26, the direction being substantially perpendicular to the axis A. In the illustrated construction, therotatable handle member 40 is formed from one continuous tubular metallic material generally formed in a U-shaped configuration, but in other constructions, therotatable handle member 40 includes two or more components attached together. Thebrackets rotatable handle member 40 proximate to a pivotingend 52 by a standard welding process or the like and also include aradial aperture rotatable handle member 40 is rotatable by about 90 degrees with respect to theframe 26. In other constructions, the arc length may be less than or greater than 90 degrees such that therotatable handle member 40 is rotatable by a different desired amount. Each distal end of theradial apertures FIG. 5 ). In other constructions, thebrackets rotatable handle member 40 by fasteners, a brazing process, or the like. - The
brackets frame 26 at the pivotingend 52 of therotatable handle member 40. Therotatable handle member 40 is movable between at least two orientations relative to theframe 26 and lockable in the two orientations by way of a spring loadedpin 58 and a removable pull pin 60 (FIG. 3 ), as will be described in greater detail below. In the illustrated construction, the spring loadedpin 58 is disposed partially within theframe 26 and projects through theradial aperture 54. Theremovable pull pin 60 is similarly disposed partially within theframe 26 and through the otherradial aperture 55. The spring loadedpin 58 relies on a translating spring (not shown) providing a bias to automatically lock thebracket 42 in position relative to theframe 26 in one orientation. Theremovable pull pin 60 is manually operated by the user to engage or disengage thebracket 44. In other constructions, the spring loadedpin 58 and theremovable pull pin 60 are configured oppositely. In yet other constructions, other mechanisms for locking therotatable handle member 40 with respect to theframe 26 may be employed. - In a
storage orientation 66, therotatable handle member 40 is substantially parallel with theelongated section 46 of theframe 26 and is locked in place by the spring loadedpin 58 and theremovable pull pin 60 engaging therespective brackets orientation 66, the portableair compressor assembly 10 is more compact and better suited for temporary storage or compactness during operation. From thestorage orientation 66, the spring loadedpin 58 and theremovable pull pin 60 are disengaged from theframe 26 enabling therotatable handle member 40 to rotate about 90 degrees to a mobile orientation 70 (shown in phantom inFIG. 1 ). In themobile orientation 70, therotatable handle member 40 is positioned for the user to easily manipulate the portableair compressor assembly 10 around a worksite. In the illustrated construction, in themobile orientation 70 therotatable handle member 40 is substantially perpendicular to theelongated section 46 of theframe 26. The spring loadedpin 58 is biased to engage thehole 56 of theradial aperture 54 of thebracket 42, locking therotatable handle member 40 in themobile orientation 70 when theradial aperture 54 is aligned with theframe 26 in the mobile orientation. Theremovable pull pin 60 engages theframe 26 and thebracket 44 to lock therotatable handle member 40 in themobile orientation 70. - With reference to
FIG. 1 ,protective strips 62 are positioned on therotatable handle member 40 primarily along theelongated section 46 of therotatable handle member 40 and along theframe 26 near thewheels 28 to protect the portableair compressor assembly 10 and other surfaces from damage when maneuvered around a worksite and from worksite to worksite. The protective strips 62 are configured from a wear-resistant polymer and are attached to the portable air compressor assembly elongatedsection 46 by fasteners. In other constructions, theprotective strips 62 may be attached by adhesives or the like to the portableair compressor assembly 10 and positioned in different locations and orientations on therigid structure 16. - The
rotatable handle member 40 further includes aprotective mesh 64. Theprotective mesh 64 includes relatively small gauge wire configured in a grid pattern to protect a top region of the portableair compressor assembly 10 from damage. In the illustrated construction, theprotective mesh 64 primarily covers theelongated section 46 of therotatable handle member 40, but in other constructions, theprotective mesh 64 transitions into thebent section 48 of therotatable handle member 40. -
FIG. 2 illustrates the bottom of the portableair compressor assembly 10. At least twocross frames frame 26 adding structural rigidity to therigid structure 16. In addition, amount plate 76 is coupled to the cross frames 72, 74, disposed substantially perpendicular to the cross frames 72, 74, and is positioned below theprime mover 18 and thepump 20 to support and mount theprime mover 18 and thepump 20 to therigid structure 16. - With reference to
FIG. 3 , thecompressor component unit 12 includes the fixedair tank 22 oriented below a second orportable air tank 78 and adjacent theprime mover 18 and thepump 20. The fixedair tank 22 is fixedly coupled to therigid structure 16 and further secured to the cross frames 72, 74. The fixedair tank 22 defines a longitudinal axis B disposed generally perpendicular to the cross frames 72, 74 (FIG. 2 ) and aligned substantially parallel with the substantially elongatedsection 46 of theframe 26. In addition, theportable air tank 78 defines a longitudinal axis C disposed generally perpendicular to the cross frames 72, 74 (FIG. 6 ) and aligned substantially parallel with the substantially elongatedsection 46 of theframe 26. The longitudinal axis B and the longitudinal axis C are substantially parallel with respect to each other when theportable air tank 78 is mechanically coupled to the fixedair tank 22. Furthermore, the fixedair tank 22 and theportable air tank 78 are stacked such that the longitudinal axes B and C lie in a plane (e.g., a vertical plane) that is substantially perpendicular to the support plane 34 (e.g., a horizontal plane). That is, the fixedair tank 22 is substantially between theportable air tank 78 and thesupports 30. In other constructions, the longitudinal axis B and the longitudinal axis C are offset from each other with respect to thesupport plane 34. -
FIG. 4 illustrates a left side view of the portableair compressor assembly 10 including a left side profile of the fixedair tank 22. Apressure gauge 82 and arelief valve 84 are fluidly coupled to the fixedair tank 22. Thepressure gauge 82 measures the pressure within the fixedair tank 22 and displays the pressure measurement on ananalog dial 86 that faces outwardly from the fixedair tank 22. Theanalog dial 86 displays pressure in English units (e.g., p.s.i.) and/or International units (e.g., Pascal). In other constructions, thepressure gauge 82 includes a digital display. In addition, therelief valve 84 is calibrated to open when pressure within the fixedair tank 22 reaches a predetermined level. - The
pump 20 and the fixedair tank 22 are in fluid communication via aninlet conduit 80 disposed between thepump 20 and the fixedair tank 22 for conveying compressed air from thepump 20 to the fixedair tank 22. Furthermore, the fixedair tank 22 is in fluid communication with theportable air tank 78 by way of anoutlet conduit 88 coupled between thefixed air tank 22 and the portable air tank 78 (FIG. 3 ). Theoutlet conduit 88 includes acontrol valve 90 disposed therein to provide the user selective control to allow pressurized air to communicate between thefixed air tank 22 and theportable air tank 78 or to isolate the fixedair tank 22 from theportable air tank 78. In the illustrated construction, thecontrol valve 90 is a ball valve, but in other constructions, thecontrol valve 90 is configured as a globe valve, a gate valve, or the like. -
FIG. 6 illustrates a top view of the portableair compressor assembly 10 with theprotective mesh 64 removed to better illustrate components of the portableair compressor assembly 10. Theoutlet conduit 88 is fluidly coupled to theportable air tank 78 via a quick-disconnect fitting 106. In addition, the quick-disconnect fitting 106 functions as a check valve to allow air into theportable air tank 78 and prevent air from escaping from theportable air tank 78 by way of theoutlet conduit 88. The quick-disconnect fitting 106 provides an easy detachment mechanism for fluidly disconnecting theoutlet conduit 88 and theportable air tank 78, e.g., when theportable air tank 78 is removed. - With reference to
FIG. 3 andFIG. 8 , the fixedair tank 22 also includes mountingbrackets air tanks brackets air tank 22 by a standard welding process or the like near a top circumferential side surface of the fixedair tank 22. - With reference to
FIG. 5 andFIG. 8 , theportable air tank 22 is removably coupled by way of aretainer 96, such as a compression retainer. In the illustrated construction, tworetainers 96 are employed; however, in other constructions, one, three, or more retainers may be employed. In the illustrated construction, thecompression retainers 96 are formed as a continuous elastic metal strip primarily formed in a substantially semicircular shape in cross section perpendicular to the longitudinal axis B of the fixedair tank 22. Thecompression retainers 96 define a substantiallysemicircular opening 98. Thecompression retainers 96 have a radius slightly smaller than a radius of theportable air tank 78, thereby providing a compressive force for holding theportable air tank 78 when theportable air tank 78 is pressed into thesemicircular opening 98. Thecompression retainers 96 are coupled to the fixedair tank 22 by way of mountingbrackets retainer bracket portion air tank 22 and located away from thesemicircular opening 98. Eachretainer bracket portion bracket air tank 22. In addition, eachcompression retainer 96 includes a compressionretainer lip portion 104 that changes in contour proximate a distal end of thesemicircular opening 98. In other constructions, other types of retainers may be employed. For example, the retainer may include another type of clip or snap-fit mechanism, a fastener, a detent mechanism, a latch mechanism, etc. In yet other constructions, theportable air tank 78 may be removably coupled to another portion of thecompressor component unit 12, such as theprime mover 18 or thepump 20. In yet other constructions, theportable air tank 78 may be removably coupled to other portions of the portableair compressor assembly 10, such as therigid structure 16, etc. - With reference to
FIG. 6 , thetank unit 14 includes amanifold assembly 107 fixed to theportable air tank 78 and positioned between theportable air tank 78 and theprime mover 18 when theportable air tank 78 is secured to the fixedair tank 22 by thecompression retainers 96. Themanifold assembly 107 includes amanifold body 108 having aregulator knob 110 and pressure gauges. In the illustrated construction, themanifold body 108 includes atank pressure gauge 112 and anoutput pressure gauge 114. Asupply conduit 116 fluidly couples a first side of themanifold body 108 to theportable air tank 78. Thetank pressure gauge 112 measures the air pressure within theportable air tank 78 fluidly between the quick-disconnect fitting 106 and theregulator knob 110. Theoutput pressure gauge 114 measures the air pressure fluidly between theregulator knob 110 and a pneumatic tool that is fluidly connected to themanifold assembly 107 by a quick-disconnect manifold outlet 118. Theregulator knob 110 is rotatably coupled to themanifold body 108 and includes a regulator valve for altering the air pressure supplied from theportable air tank 78 to the pneumatic tool. In addition, thesupply conduit 116 includes arelief valve 120 similar to the relief valve 84 (FIG. 4 ) for relieving pressure within theportable air tank 78 when the pressure reaches the predetermined level. The quick-disconnect manifold outlet 118 includes dual quick-disconnects 122 (e.g., two quick-disconnects) configured to supply a plurality of pneumatic tools with compressed air. In other constructions, thedual disconnects 122 include a single or more than two connections to supply pneumatic tool(s). - With reference to
FIG. 6 andFIG. 7 , thetank unit 14 also includes atank handle 124 rotatably coupled to theportable air tank 78 by way ofhandle brackets 126 and pins 128. The tank handle includes agrip 130 formed from a polymeric material or the like and designed to ergonomically suit the hand of a user. The location of the tank handle 124 with respect to theportable air tank 78 and themanifold assembly 107 is such that theportable air tank 78 is balanced and easily movable by a user from thecompressor component unit 12 to a desired location away from thecompressor component unit 12. In the illustrated construction, the tank handle 124 is configured from tubular metal. In other constructions, thetank handle 124 and thegrip 130 may be formed from other suitable materials.Support feet 132 are coupled to thetank unit 14 and provide a support base that contacts the support surface 34 (e.g., the ground), as shown inFIG. 7 . Thesupport feet 132 are substantially aligned in a plane, e.g., thesupport plane 34. In the illustrated construction, twosupport feet 132 are coupled to themanifold body 108 and twosupport feet 132 are coupled to the portable air tank 78 (FIG. 4 ) to provide a sturdy base when thetank unit 14 is removed. In other constructions, thesupport feet 132 are only coupled to theportable air tank 78, only coupled to themanifold assembly 107, or various combinations thereof, e.g., twosupport feet 132 are coupled to themanifold assembly 107 and onesupport foot 132 is coupled to theportable air tank 78, vice-versa, etc. - The
manifold body 108 is substantially planar and is disposed at an angle D with respect to the support plane 34 (e.g., with respect to thesupport feet 132 substantially aligned in the support plane 34). In the illustrated construction, the angle D is about 45 degrees (FIG. 8 ). Preferably, the angle D is 45 degrees+/−2 degrees. In other constructions, the angle D may be between about 30 and about 60 degrees. In yet other constructions, the angle D may be greater than 0 degrees and less than about 90 degrees. This allows thegauges regulator knob 110 to be easily viewed when thetank unit 14 is used while resting on thesupport feet 132. - In operation, the portable
air compressor assembly 10 is transported to a worksite (e.g., via a truck). The user uses theprotective strips 62 to orientate and safely move the portableair compressor assembly 10 to not damage the portableair compressor assembly 10 or the truck. The user rotates therotatable handle member 40 from thestorage orientation 66 to themobile orientation 70 by disengaging the spring loadedpin 58 and theremovable pull pin 60, rotating therotatable handle member 40 upwards, and reengaging the spring loadedpin 58 and theremovable pull pin 60 to lock therotatable handle member 40 in themobile orientation 70. The user manipulates the transport handle 50 to move the portableair compressor assembly 10 to a desired location, e.g., by grasping thetransport handle 50, pivoting the portableair compressor assembly 10 about the axis A such that thesupports 30 disengage thesupport surface 34, and pulling or pushing thetransport handle 50. - To start filling both
air tanks pump 20, the user opens thecontrol valve 90 to fluidly connect thecompressor component unit 12 to thetank unit 14. Once the user starts theprime mover 18, rotational power is supplied to thepump 20 by theflywheel 24. Compressed air then moves from thepump 20 through theinlet conduit 80 and theoutlet conduit 88 into the fixedair tank 22 and theportable air tank 78. Thepump 20 supplies bothair tanks air tanks compressor component unit 12 is activated while thecontrol valve 90 is closed, then only the fixedair tank 22 will fill with compressed air. - To remove the
tank unit 14 from thecompressor component unit 12, the user closes thecontrol valve 90 and disconnects theoutlet conduit 88 from the quick-disconnect fitting 106, causing thetank unit 14 to be fluidly separated from thecompressor component unit 12. Then, the user grasps thehandle 124 to pull thetank unit 14 up and away from thecompressor component unit 12 to overcome the elastic compression forces of thecompression retainers 96 that secure theportable air tank 78 to the fixedair tank 22. With thetank unit 14 positioned away from thecompressor component unit 12, thetank unit 14 rests on and is supported by thesupport feet 132. - To replace the
tank unit 14 on the compressor component unit 12 (FIG. 1 ), the user orientates thetank unit 14 above thelip portion 104 such that the longitudinal axes B and C are substantially parallel and moves thetank unit 14 down towards thesemicircular opening 98. Thelip portion 104 initially receives theportable air tank 78 to align theportable air tank 78 with thecompression retainers 96. The user applies a further force upon the portable air tank 78 (if the force of gravity is not sufficient) such that thecompression retainers 96 expand over theportable air tank 78 and secure thetank unit 14 to thecompressor component unit 12. Then, the user may fluidly reconnect thetank unit 14 to thecompressor component unit 12 by connecting theoutlet conduit 88 to the quick-disconnect fitting 106. - The user may use the portable
air compressor assembly 10 in three distinct configurations. - With reference to
FIG. 1 , the portableair compressor assembly 10 may be maintained as one unit with theair tanks compression retainers 96. In this configuration, the full functionality of the portableair compressor assembly 10 is maintained, and the total air pressure from bothair tanks manifold assembly 107. Thepressure gauge 86 may also be used to monitor the pressure in the fixedair tank 22. - With reference to
FIG. 8 , a second configuration is illustrated with thetank unit 14 removed and positioned away from thecompressor component unit 12 with an air hose 68 fluidly connecting theair tanks tank unit 14 and thecompressor component unit 12. The air hose 68 may be any quick-connect hose. From the first configuration, the user disconnects and removes thetank unit 14 as described above. The user may position thetank unit 14 away from thecompressor component unit 12 and fluidly connect the air hose 68 to the quick-disconnect fitting 106 and to theoutlet conduit 88, thereby fluidly reconnecting thetank unit 14 to thecompressor component unit 12 at a longer distance. The second configuration is advantageous when the user does not want the entire portableair compressor assembly 10 to be in one location. Rather, thetank unit 14 may be positioned proximate to the work area, and thecompressor component unit 12 with therigid structure 16 may be positioned away from the work area to reduce unwanted noise and vibrations from theprime mover 18 around the work area as well as to increase to portability of the portableair compressor assembly 10. In this configuration, the total air pressure from bothtanks manifold assembly 107. Thepressure gauge 86 may also be used to monitor the pressure in the fixedair tank 22. - With reference to
FIG. 7 , a third configuration is illustrated with thetank unit 14 independent from thecompressor component unit 12. From the first configuration, the user disconnects and removes thetank unit 14 as described above. The user may then position thetank unit 14 away from thecompressor component unit 12 at any distance and use thetank unit 14 independently from thecompressor component unit 12. The third configuration is advantageous when the user requires maximum portability of the portableair compressor assembly 10 or the worksite requires a relatively small amount of compressed air. In this configuration, the air pressure within thetank unit 14 can be monitored and regulated by themanifold assembly 107. - The user may use the
tank unit 14 in any of these configurations by connecting a pneumatic tool(s) to at least one of the dual quick-disconnects 122 by way of an air hose (not shown) and controlling theregulator knob 110 to provide a desired supply pressure to the pneumatic tool(s). - Various features of the invention are set forth in the following claims.
