The manifold assembly may be attached directly to the air compressor, or, alternately, removed from the air compressor and coupled thereto via an air conduit, e.g., an air hose or the like, so that the manifold assembly can be used at locations remote from the air compressor.
Description




FIELD OF THE INVENTION




The present invention generally relates to the field of air compressors, and more particularly to an air compressor having a removable manifold assembly capable of being remotely located from the air compressor for controlling and distributing compressed air from the air compressor to one or more air powered tools.




BACKGROUND OF THE INVENTION




Air compressors are used to provide compressed air for operating air powered tools such as nailing tools, socket driving tools, material shaping tools, sanding tools, spray painting tools, inflation chucks, and the like. Frequently, it is desirable to operate several tools from air supplied by a single air compressor. In such instances, the air outlet port or “pressure manifold” of the air compressor is fitted with an adapter allowing the attachment and removal of multiple air hoses for providing air to operate several air powered tools at once. However, in many applications, the air compressor must be located remotely from the workers utilizing the tools for which it provides air. For instance, at a typical construction site, a single air compressor may be required to provide air to operate a plurality of tools, which, because of the physical layout of the site, are used at locations where the air compressor cannot be transported. For example, workers may be working in an upper story of an unfinished building while the air compressor is located on the first story. Similarly, wherein the air compressor is driven by an electric motor, it may be desirable to situate the air compressor near a source of electrical power such as an electrical outlet, an electrical generator, a vehicle, or the like. As a result, the amount of air hose required to couple the air compressor to each tool is greatly increased, in many cases becoming unwieldy to store and transport. Further, because workers are remotely located from the air compressor, they often cannot readily access the air compressor's pressure regulator and pressure gauges to control the amount of pressure being provided to their tools.




Consequently, it would be advantageous to provide an air compressor having a removable manifold assembly that can be remotely located from the air compressor and attached thereto via a single air hose for distributing compressed air from the air compressor to multiple air powered tools. Such a manifold assembly should provide means for adjusting the air pressure provided to the air powered tools and for indicating pressures within the compressed air storage tank and manifold outlet pressure remotely.




SUMMARY OF THE INVENTION




Accordingly, the present invention is directed to a manifold assembly for an air compressor that is capable of controlling and distributing compressed air from the air compressor to one or more air powered tools. The manifold assembly may be attached directly to the air compressor, or, alternately, removed from the air compressor and coupled thereto via a conduit such as an air hose or the like, so that the manifold assembly can be used at locations remote from the air compressor. In exemplary embodiments of the invention, the manifold assembly may include a pressure regulator assembly for regulating the pressure of air provided to the air powered tools and indicators for indicating the pressure of compressed air in the air compressor's compressed air storage tank and/or the manifold assembly's outlet pressure.

DETAILED DESCRIPTION OF THE INVENTION




Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.




Referring generally to

FIGS. 1 through 4

, an air compressor


100


in accordance with an exemplary embodiment of the present invention is described. As shown in

FIGS. 1 and 2

, the air compressor


100


includes a compressor


102


mounted to a compressed air storage tank


104


. The compressed air storage tank


104


provides a reservoir or receiver for storing air under pressure. A port (often referred to as a “spud”) is provided in the compressed air storage tank


104


to which a pressure manifold or pipe


106


is fitted allowing compressed air to be drawn from the tank


104


for powering air powered tools such as nailing tools, socket driving tools, material shaping tools, sanding tools, spray painting tools, tire inflation chucks, and the like.




A pressure switch assembly


108


is mounted to the pressure manifold


106


for regulating pressure within the compressed air storage tank


104


by alternately starting and stopping the compressor


102


to periodically replenish the supply of air in the tank


104


. When pressure within the tank


104


reaches a preset low pressure point, or “kick-in pressure”, the pressure switch assembly


108


starts the compressor


102


to re-pressurize the tank


104


. As the pressure within the tank


104


reaches a preset high pressure point, or “kick-out pressure”, the pressure switch assembly


108


stops the compressor


102


to prevent over-pressurization of the tank


104


. In this manner, the pressure of the compressed air in the compressed air storage tank


104


is maintained within a range generally suitable for powering one or more air powered tools. The pressure manifold


106


may include a safety pressure relief valve for relieving pressure within the pressure manifold


106


. In accordance with an exemplary embodiment, the pressure relief valve is opened by a user by pulling outward on an enlarged ring having a tab or “fob”


109


providing a label surface attached thereto. Preferably, the ring and fob


109


are sized to be easily gripped by users of the air compressor


100


to open the safety pressure relief valve.




In accordance with an exemplary embodiment of the present invention, the air compressor


100


is provided with a manifold assembly


110


for controlling and distributing compressed air from the air compressor to one or more air powered tools. The manifold assembly


110


may be attached directly to the air compressor


100


, as shown in

FIG. 1

, or, alternately, removed from the air compressor


100


, as shown in

FIG. 2

, and coupled thereto via a single air hose allowing the manifold assembly to be utilized at locations remote from the air compressor


100


(see

FIGS. 11

,


12


and


13


). The manifold assembly


110


is comprised of a pneumatic manifold


112


and pressure regulator assembly


114


supported in a housing or frame


116


. In

FIGS. 1 through 4

, the pneumatic manifold


112


and frame


116


are shown as separate components attached together by suitable fasteners. However, it should be appreciated that the pneumatic manifold


112


and frame may be of one-piece construction without departing from the scope and spirit of the present invention.




As shown in

FIGS. 3 and 4

, the pneumatic manifold


112


includes an inlet port


118


coupled to one or more outlet ports (four outlet ports


120


,


122


,


124


&


126


are shown) via an internal passage


127


. The outlet ports


120


,


122


,


124


&


126


are fitted with suitable couplers or connectors


128


,


130


,


132


&


134


which extend through apertures formed in the frame


116


allowing for attachment and removal of air hoses between the manifold assembly


110


and one or more air powered tools (see

FIGS. 11

,


12


and


13


). For instance, in exemplary embodiments of the invention, couplers


128


,


130


,


132


&


134


may be comprised of quick-connect coupler bodies for allowing attachment and removal of air hoses without the use of tools. Alternately, one or more of the outlet ports


120


,


122


,


124


&


126


may be fitted with a quick-connect coupler plug or stud allowing attachment of air hoses equipped with a quick-connect coupler bodies, a threaded connector (male or female), or the like as contemplated by one of ordinary skill in the art.




The pressure regulator assembly


114


is coupled to the pneumatic manifold


112


via inlet port


118


. In one embodiment, shown in

FIG. 3

, the pressure regulator assembly


114


includes a single pressure regulator valve


136


that may be opened and closed by a user of the air compressor


100


, for example, by turning a knob


138


extending through an aperture


140


formed in the face


142


of frame


116


, to regulate the pressure of compressed air within the pneumatic manifold


112


and provided at outlet ports


120


,


122


,


124


&


126


. Alternately, multiple pressure regulator valves may be provided for regulating the pressure provided at each outlet port


120


,


122


,


124


&


126


independently, or at specific groups of the outlet ports


120


,


122


,


124


&


126


. The pressure regulator assembly


114


may further include indicators for indicating pressures within the air compressor


100


and/or manifold assembly


110


. For instance, as shown in

FIG. 3

, the manifold assembly may include an indicator


144


for indicating the pressure of unregulated compressed air in the compressed air storage tank


104


and pressure manifold


106


, and an indicator


146


for indicating the regulated pressure of compressed air in the pneumatic manifold


112


. In exemplary embodiments, the indicators


144


&


146


are comprised of high pressure gauges coupled to ports


148


&


150


in the pressure regulator valve


136


, and oriented so that the dials of the gauges are viewable through apertures formed in the face


142


of the manifold assembly frame


116


.




The manifold assembly


110


is coupled to pressure manifold


106


via a suitable coupling device


152


allowing it to be quickly and easily removed from the air compressor


100


. In one embodiment shown in

FIGS. 3 and 4

, the coupling device


152


is comprised of a quick-connect coupler body


154


fitted to the outlet port


156


of pressure manifold


106


. This quick-connect coupler body


154


mates with a corresponding quick-connect coupler plug or stud


158


fitted to the inlet port


160


of the manifold assembly's pressure regulator assembly


114


when the manifold assembly


110


is directly attached to the air compressor


100


, as shown in FIG.


1


. Preferably, when mated together, the quick-connect coupler plug


158


is retained within the quick-connect coupler body


154


until physically uncoupled by a user of the air compressor


100


to remove the manifold assembly


110


. The coupling device


152


thus provides both a pneumatic connection between the manifold assembly


110


and the pressure manifold


106


, and a mechanical connection between the manifold assembly


110


and the compressed air storage tank


104


for at least partially securing the manifold assembly


110


to the air compressor


100


and eliminating the need for separate latching or locking mechanisms to perform this function. However, it will be appreciated that supplementary latching or locking mechanisms may be provided to further secure the manifold assembly


110


to the air compressor


100


if desired. Further, when the manifold assembly


110


is removed from the air compressor


100


, as shown in

FIG. 2

, the quick-connect coupler body


154


may be mated to a quick connect coupler plug fitted to a first end of the air hose (not shown) providing a pneumatic connection between the pressure manifold


106


and air hose. Likewise, the quick connect coupler plug


158


may be mated to a quick connect coupler body fitted to a second end of the hose, pneumatically coupling the air hose to the manifold assembly


110


so that air may be provided to the manifold assembly


110


.




Turning now to

FIGS. 2 and 4

, the compressed air storage tank


104


may further be provided with a mounting bracket


162


for supporting the manifold assembly


110


while it is directly attached to the air compressor


100


. In an exemplary embodiment, the lower portion of the manifold assembly frame


116


includes one or more tabs


164


spaced so as to be generally aligned with notches or openings


166


formed in mounting bracket


162


. When the manifold assembly


110


is attached to the air compressor


100


, as shown in

FIGS. 1 and 4

, these tabs


164


extend through the openings


166


so as to at least partially rest on supports


168


formed in the mounting bracket


162


. As the manifold assembly


110


is slid rearward, i.e., toward the pressure manifold


106


, so that the quick-connect coupler plug


158


fitted thereto may be mated with the quick-connect coupler body


154


fitted to the pressure manifold


106


, the tabs


164


engage the mounting bracket


162


by at least partially sliding under the bracket's upper face


170


, attaching the manifold assembly


110


to the compressed air storage tank


104


. As shown in

FIG. 4

, the bottom surface of each tab


164


may include small knob or foot


172


preferably formed of a non-marring, wear resistant material such as plastic, a composite, or the like. When the manifold assembly


110


is attached to the air compressor


100


, this foot


172


substantially fills any gap between the tab


164


and the support


168


to prevent excessive play between the manifold assembly


110


and mounting bracket


162


.




Referring now to

FIGS. 5 and 6

, an air compressor


200


having a manifold assembly


202


in accordance with a further exemplary embodiment of the present invention is described. The manifold assembly


202


includes a pneumatic manifold


204


and pressure regulator assembly


206


mounted to a frame


208


capable of being attached to the side wall


210


of the air compressor's compressed air storage tank


212


. Outlet ports


214


in the pneumatic manifold


204


are fitted with couplers or connectors


216


for allowing attachment and removal of air hoses (not shown) to provide compressed air to one or more air powered tools (see

FIGS. 11

,


12


and


13


). In exemplary embodiments of the invention, these couplers


216


may be comprised of quick-connect coupler bodies for allowing attachment and removal of air hoses without the use of tools. Alternately, the couplers


216


may comprise quick-connect coupler plugs allowing attachment of air hoses equipped with a quick-connect coupler bodies, a threaded connector (male or female), or the like as contemplated by one of ordinary skill in the art.




The pressure regulator assembly


206


includes one or more pressure regulator valves


220


that may be opened and closed by a user of the air compressor


200


to regulate the pressure of compressed air provided at outlet ports


214


. Indicators may be provided for indicating various pressures within the air compressor/air hose/manifold assembly/air powered tool system. For example, as shown in

FIG. 5

, the manifold assembly


202


includes a single pressure gauge


222


for indicating the regulated pressure of compressed air in the pneumatic manifold


204


.




The manifold assembly


202


is pneumatically coupled to the air compressor


200


via a short length of air hose


224


extending between the inlet port


226


of the manifold assembly's pressure regulator valve


220


and the outlet port


228


of a second pressure regulator assembly


230


mounted to the compressed air storage tank


212


and coupled to the compressed air storage tank's pressure manifold. As shown in

FIG. 5

, the second pressure regulator assembly


230


may include a pressure regulator valve


232


for regulating the pressure of compressed air provided at outlet port


228


and one or more indicators (pressure gauges


234


&


236


are shown) for indicating pressures within the air compressor/manifold assembly system. In this manner, the pressure provided to manifold assembly


202


may be regulated at the air compressor


200


while the manifold assembly


202


is being used remotely. Further, the air compressor


200


may be used independently of manifold assembly


202


if desired.




Quick-connect coupler devices


240


&


242


connect the air hose


224


to inlet port


226


and outlet port


228


allowing the air hose


224


to be easily disconnected from either port. In this manner, a longer length of air hose may be provided between the air compressor


200


and manifold assembly


202


when the manifold assembly


202


is removed from the compressed air storage tank


212


, for example, when being used at a remote location. Such a longer length of air hose may, for example, be coupled between the inlet port


226


and air hose


224


, between air hose


224


and outlet port


228


, or directly between inlet port


226


and outlet port


228


, air hose


224


being completely removed.




A latching assembly


244


may be provided for securing the manifold assembly


202


to the air storage tank


212


. In an exemplary embodiment, the latching assembly


244


is comprised of clamps


246


&


248


which may be closed on a flanges


250


&


252


formed in the manifold assembly's frame


208


to secure the manifold assembly to the side of the air tank


212


. When opened, the clamps


246


&


248


release the flanges


250


&


252


allowing the manifold assembly to be lifted from the side of the air storage tank


212


for use at a remote location. It will now be appreciated that the latching assembly


244


may utilize other latching mechanisms for securing the manifold assembly to compressed air storage tank and substitution of such alternative latching mechanisms for those specifically described herein by those of skill in the art is possible and such substitution would not depart from the scope and spirit of the present invention as set forth in the appended claims.




In

FIGS. 1 through 6

, manifold assemblies in accordance with the present invention are shown configured for use with an air compressor having a single horizontally disposed, cylindrical compressed air storage tank, typically referred to informally in the art as a “hot-dog” style tank. However, it should be appreciated that air compressors utilizing manifold assemblies in accordance with the present invention may employ a wide variety of compressed air storage tank configurations. For example, instead of the generally horizontal compressed air storage tank shown in

FIGS. 1 through 6

, an air compressor employing the manifold assembly of the present invention may, for example, comprise a vertically disposed “hot-dog” style tank or a flattened oval tank, often referred to informally in the art as a “pancake” style tank. Similarly, instead of the single large tank shown, an air compressor employing a manifold assembly in accordance with the present invention may utilize two or more smaller air storage tanks. For example, such an air compressor may employ two horizontally disposed cylindrical compressed air storage tanks positioned side by side, a tank configuration often referred to informally in the art as a “double hot-dog” style tank. Use of such tank configurations would not depart from the scope and spirit of the present invention.

thereby connecting the manifold assembly


314


,


414


and air compressor


300


,


400


so that air may be provided to the manifold assembly


314


,


414


.

Referring now to

FIG. 11

, use of an air compressor having a manifold assembly in accordance with an exemplary embodiment of the present invention is described. In a typical work site


500


, such as a residential home construction site (shown), a worker


502


may utilize an air powered tool


504


(a nailing tool is shown) to perform a task or series of tasks. For example, in the construction of a residential structure


506


, a worker


502


may utilize air powered tools


504


for performing tasks such as framing walls within the structure


506


, hanging dry wall, installing windows or doors, installing roofing, installing flooring, providing interior finishing of the structure, and the like.




Because of constraints at the work site, it may be necessary that the air compressor


508


, providing a source of compressed air for operating the tool


504


be located remotely from the worker


502


. For example, when building a multiple level structure


506


, the air compressor


508


may be located in a lower level


510


of the structure


506


, while the worker


502


must perform a task in an upper level or floor


512


of the structure


506


. In such applications, the manifold assembly


514


may be detached from the air compressor


508


and coupled thereto via an air hose


516


allowing the manifold assembly


514


to be taken to the worker's location, e.g., in

FIG. 11

, the upper level


512


of the structure


506


. The worker


502


may then couple the air powered tool


504


to the manifold assembly


514


via a second air hose


518


to provide compressed air for powering the tool


504


. As discussed in the description of

FIGS. 1 through 10

, the manifold assembly may include a pressure regulator assembly and indicators for indicating various pressures within the air compressor


508


and manifold assembly


514


thereby allowing the user to monitor and control the pressure of the air provided to the tool


504


without returning to the air compressor's location, e.g., in

FIG. 11

, the lower level


510


of the structure


506


.




Turning now to

FIG. 12

, an exemplary manifold assembly is shown secured to a supporting structure at a work site. In a typical work site


600


, such as a construction site or the like, the manifold assembly


602


may be secured to a supporting structure


604


, such as a 2×4 framing member, a wall, a floor surface, a work table, or the like to provide a convenient means of locating the manifold assembly at the site


600


. In an exemplary embodiment, the manifold assembly's frame


606


may include a flange


608


having one or more holes formed therein. Fasteners


610


such as a nails (shown), screws, bolts, or the like may extend or be driven though these holes for attaching the manifold assembly to the supporting structure


604


. Alternately, one or more clamps may be provided for clamping the manifold assembly


602


to the supporting structure


604


, or, the manifold assembly may be provided with a stand or base suitable for supporting the manifold assembly on a generally horizontal surface such as a table top, a floor, or the ground (see FIG.


11


).




Small knobs or feet


612


formed of a non-marring, wear resistant material such as plastic, a composite, or the like on the bottom surface of the frame


606


prevent direct contact with the frame


606


and supporting structure


604


for preventing unnecessary damage to the supporting structure


604


or manifold assembly


602


due to contact or rubbing during use. An air hose


614


is connected to inlet port


616


of the manifold assembly


602


for pneumatically coupling the manifold assembly


602


to an air compressor (not shown). Similarly, one or more air hoses


618


,


620


,


622


&


624


may be connected to outlet ports


626


,


628


,


630


&


632


for coupling one or more air powered tools (not shown) to the manifold assembly


602


. A pressure regulator assembly


634


and indicators such as pressure gauges


636


&


638


allow users to monitor and control the pressure of air provided at the outlet ports


626


,


628


,


630


&


632


.




Referring now to

FIG. 13

, in accordance with an exemplary embodiment of the invention multiple manifold assemblies may be chained together to provide compressed air to air powered tools at several locations in a work site. In a typical work site


700


, such as a construction site or the like, a first manifold assembly


702


may be pneumatically coupled to an air compressor via an air hose


706


. As shown in

FIG. 13

, the first manifold assembly


702


may be secured to a supporting structure, such as a 2×4 framing member (shown), a wall, a floor surface, a work table, or the like at a first location at the work site


700


. A second manifold assembly


704


is coupled to an outlet port of the first manifold assembly


702


via an air hose


708


. The second manifold assembly


704


may be secured to a supporting structure, such as a floor surface, a 2×4 framing member, a wall, a work table, or the like at a second location at the work site


700


. One or more air powered tools


710


,


712


,


714


&


716


may by pneumatically coupled to either the first manifold assembly


702


or second manifold assembly


704


via air hoses


718


,


720


,


722


&


724


for use at either the first location or the second location, respectively. In this manner, compressed air may be supplied to multiple locations within a work site from a single air compressor (not shown) for powering air powered tools at each location. Alternately, multiple manifold assemblies may be located within close proximity to each other so that compressed air may be supplied to a greater number of tools that would be possible with a single manifold assembly.




In

FIGS. 1 through 13

, the air compressor is illustrated as having a compressor of the type having a reciprocating piston pump driven by an electric motor. However, it should be appreciated that air compressors having manifold assemblies in accordance with the present invention may employ other compressor technologies. For instance, an air compressor might employ a reciprocating piston pump driven by a small internal combustion engine via a belt drive, a rotary or turbine pump driven by an electric motor or internal combustion engine, and the like. Use of such alternate compressor technologies would not depart from the scope and spirit of the present invention.




It will be appreciated that manifold assemblies in accordance with the present invention may at times be removed from the air compressor and used within the immediate vicinity of the air compressor. Consequently, the terms “remote”, “remotely located” and “remote location” utilized herein should not be limited by the distance separating the manifold assembly and air compressor. Instead, such terms should be construed as encompassing any use of the manifold assembly while detached from the air compressor regardless of the distance of separation between the manifold assembly and air compressor.




It is believed that the manifold assembly of the present invention and many of its attendant advantages will be understood by the forgoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages, the form herein before described being merely an explanatory embodiment thereof.
