Description




FIELD OF THE INVENTION




The present invention relates generally to the field of air compressors, and more particularly to an air compressor assembly having one or more of the following features: a removable manifold assembly capable of being remotely located from the air compressor assembly for controlling and distributing compressed air from the air compressor assembly to one or more air powered tools, a lifting handle, a handle capable of assuming a plurality of positions, condensate removal devices, and a stable base and tie-down points.




BACKGROUND OF THE INVENTION




Air compressor assemblies 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 assembly. In such instances, the air outlet port or “pressure manifold” of the air compressor assembly 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 assembly 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 assembly 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 assembly cannot be transported. For example, workers may be working in an upper story of an unfinished building while the air compressor assembly is located on the first story. Similarly, wherein the air compressor assembly is driven by an electric motor, it may be desirable to situate the air compressor assembly 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 assembly to each tool is greatly increased, in many cases becoming unwieldy to store and transport. Furthermore, because workers are remotely located from the air compressor assembly, they often cannot readily access the air compressor assembly'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 assembly having a removable manifold assembly that can be remotely located from the air compressor assembly and attached thereto via a single air hose for distributing compressed air from the air compressor assembly 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.




Air compressor assemblies in portable applications are typically transported with the use of a wheel assembly and a transport handle assembly used to guide the air compressor assembly when utilizing the wheel assembly. However, a typical transport handle assembly is not suited for lifting the air compressor assembly, such as when the air compressor assembly is loaded into a truck, needs to be transported over stairs, is lifted over uneven ground, and the like. For example, a typical transport handle may be positioned at one end of the air compressor assembly, thereby providing support to only one end of the air compressor assembly. Furthermore, an air compressor assembly may weigh hundreds of pounds, thereby requiring a substantial force to be exerted to lift the air compressor assembly.




The failure of the typical transport handle assembly to supply an accommodating way of lifting the air compressor assembly often requires users, when trying to lift the air compressor assembly to wrap their arms around the air storage tank, grasp a wheel assembly, grip the motor assembly, and engage in other very difficult and unsure maneuvers. These maneuvers may cause damage to the air compressor assembly and even injury to the user due to the size and weight of a typical air compressor assembly.




Thus, it would be advantageous to provide an air compressor assembly including a lifting handle and/or a handle capable of assuming a plurality of positions.




Conventionally, a condensate removal device is placed in proximity to a low point of a compressed air tank within an air compressor assembly to remove condensate that may form within a compressed air tank. During the utilization of a compressed air tank, it is common for water and other liquids to condense from the air inside the air tank as a consequence of the pressure and temperature differences inside the tank and outside the tank. Water and other liquids that may accumulate inside the air tank may be removed through the installation of a condensate removal device placed near a low point of the air tank. Typically, condensate removal devices known to the art are valves that may be opened and closed easily yet are capable of maintaining a constant pressure inside the air tank.




Since compressed air tanks tend to be large and heavy, they may not be easily transported. As a result, typical mobile compressed air tanks may be fitted to a frame comprising wheels and handlebars. This allows a person or persons to lift the compressed air tank and pull or push it to a desired location. While traveling on a smooth surface, the design works well. However, in many construction sites, movement to a remote location over an uneven and unpaved surface may be necessary. A frequent problem that occurs while moving the compressed air tank to a remote location is that the drain valve for removing condensate from an air tank may be damaged during transport to a remote location. Foreign objects tend to come into contact with the valve during transport causing damage to the valve. Another problem is that compressed air tanks may be moved during the day and typically are placed upon the bed of a pickup truck in order to transport the compressed air tank to another worksite. Since typical compressed air tanks are heavy, it is not easy for persons to use care and caution when placing the compressed air tanks onto the bed of a pickup truck. Thus, the compressed air tank may be lifted and pushed onto the bed in a quick manner. Often, other items located on the bed of the truck may come into contact with the drain valve damaging the valve when the compressed air tank is placed upon the bed of a pickup truck. Upon damage to the drain valve, the compressed air tank becomes non-functional.




Thus, it would be desirable to provide an apparatus to act as a shield to prevent the condensate removal device from coming into contact with foreign objects. Furthermore, it would be advantageous if the condensate removal device could recess into a mounting device allowing the mounting device to shield the condensate removal device. Another advantageous aspect would be to cover the condensate removal device with a removable cap to protect the condensate removal device.




A popular type of air compressor assembly comprises a compressor mounted to a horizontal compressed air storage tank. The compressed air storage tank further includes a wheel assembly consisting of a wheel mounted to each side of the tank by a wheel bracket. A handle assembly and base are mounted to the air supply tank opposite the wheel assembly. The wheel assembly and base support the air compressor allowing the air compressor assembly to be transported by lifting on the handle assembly thereby raising the base from the surface on which the air compressor rests.




One long unresolved problem with such air compressor assemblies is that they tend to be top heavy due in part to the weight of the compressor above the compressed air storage tank. Furthermore, as shown in

FIG. 1

, such air compressor assembly


5


-


100


includes a base


5


-


102


which has historically been made much narrower than the width of the compressed air storage tank


5


-


104


since the three point stance provided by the base


5


-


102


and wheel assembly


5


-


106


was sufficient to balance and provide stability to the air compressor assembly


5


-


100


when used in normal consumer applications. However, when such air compressor assembly


5


-


100


is utilized in more austere environments, such as at a construction site, where the air compressor assembly


5


-


100


is much more likely to rest on rough or uneven ground, it has been discovered that excessive tension (such as a sharp pull or jerk) applied to an air hose coupled to the air compressor in a direction generally perpendicular to the side of the compressed air storage tank


5


-


104


can cause the air compressor assembly


5


-


100


tip over as shown by arrow


5


-


108


, possibly damaging the air compressor assembly or injuring its user. Similarly, when such air compressor assembly is loaded into a vehicle such as a pickup truck, or the like for transport, movement of the vehicle may cause the air compressor assembly


5


-


100


to tip over possibly damaging the air compressor assembly


5


-


100


and the vehicle. As a result, many users consider air compressor assemblies having such horizontal compressed air storage tanks less desirable for use in harsh environments than air compressor assemblies having other tank configurations.




Consequently, it would be desirable to provide a portable air compressor assembly of the type having a horizontal compressed air storage tank, wherein the air compressor assembly includes a more stable base to prevent tipping of the air compressor assembly. Furthermore, it would be desirable to provide tie-down points for securing the air compressor assembly to a vehicle for transport.

1


-


102


mounted to a compressed air storage tank


1


-


104


. The compressed air storage tank


1


-


104


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


1


-


104


to which a pressure manifold or pipe


1


-


106


is fitted allowing compressed air to be drawn from the tank


1


-


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


1


-


108


is mounted to the pressure manifold


1


-


106


for regulating pressure within the compressed air storage tank


1


-


104

1


-


108


starts the compressor


1


-


102


to re-pressurize the tank


1


-


104


. As the pressure within the tank


1


-

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


1


-


108


stops the compressor


1


-


102


to prevent over-pressurization of the tank


1


-


104


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


1


-


104


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


1


-


106


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


1


-


106


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

144


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


1


-


104


and pressure manifold


1


-


106


, and an indicator


1


-


146


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


1


-


112


. In exemplary embodiments, the indicators


1


-


144


&


1


-


146


are comprised of high pressure gauges coupled to ports


1


-


148


&


1


-


150


in the pressure regulator valve


1


-


136


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


1


-


142


of the manifold assembly frame


1


-


116


.




The manifold assembly


1


-


110


is coupled to pressure manifold


1


-


106


via a suitable coupling device


1


-


152


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


1


-


100


. In one embodiment shown in

FIGS. 4 and 5

, the coupling device


1


-


152


is comprised of a quick-connect coupler body


1


-


154


fitted to the outlet port


1


-


156


of pressure manifold


1


-


106


. This quick-connect coupler body


1


-


154


mates with a corresponding quick-connect coupler plug or stud


1


-


158


fitted to the inlet port


1


-


160


of the manifold assembly's pressure regulator assembly


1


-


114


when the manifold assembly


1


-


110


is directly attached to the air compressor assembly


1


-


100


, as shown in FIG.


2


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


1


-


158


is retained within the quick-connect coupler body


1


-


154


until physically uncoupled by a user of the air compressor assembly


1


-


100


to remove the manifold assembly


1


-


110


. The coupling device


1


-


152


thus provides both a pneumatic connection between the manifold assembly


1


-


110


and the pressure manifold


1


-


106


, and a mechanical connection between the manifold assembly


1


-


110


and the compressed air storage tank


1


-


104


for at least partially securing the manifold assembly


1


-


110


to the air compressor assembly


1


-


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


1


-


110


to the air compressor assembly


1


-


100


if desired. Further, when the manifold assembly


1


-


110


is removed from the air compressor assembly


1


-


100


, as shown in

FIG. 3

, the quick-connect coupler body


1


-


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


1


-


106


and air hose. Likewise, the quick connect coupler plug


1


-


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


1


-


110


so that air may be provided to the manifold assembly


1


-


110


.




Turning now to

FIGS. 3 and 5

, the compressed air storage tank


1


-


104


may further be provided with a mounting bracket


1


-


162


for supporting the manifold assembly


1


-


110


while it is directly attached to the air compressor assembly


1


-


100


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


1


-


116


includes one or more tabs


1


-


164


spaced so as to be generally aligned with notches or openings


1


-


166


formed in mounting bracket


1


-


162


. When the manifold assembly


1


-


110


is attached to the air compressor assembly


1


-


100


, as shown in

FIGS. 2 and 5

, these tabs


1


-


164


extend through the openings


1


-


166


so as to at least partially rest on supports


1


-


168


formed in the mounting bracket


1


-


162


. As the manifold assembly


1


-


110


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


1


-


106


, so that the quick-connect coupler plug


1


-


158


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


1


-


154


fitted to the pressure manifold


1


-


106


, the tabs


1


-


164


engage the mounting bracket


1


-


162


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


1


-


170


, attaching the manifold assembly


1


-


110


to the compressed air storage tank


1


-


104


. As shown in

FIG. 5

, the bottom surface of each tab


1


-


164


may include small knob or foot


1


-


172


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


1


-


110


is attached to the air compressor assembly


11


-


100


, this foot


1


-


172


substantially fills any gap between the tab


1


-


164


and the support


1


-


168


to prevent excessive play between the manifold assembly


1


-


110


and mounting bracket


1


-


162


.




Referring now to

FIGS. 6 and 7

, an air compressor assembly


1

-


204


and pressure regulator assembly


1


-


206


mounted to a frame


1


-


208


capable of being attached to the side wall


1


-


210


of the air compressor assembly's compressed air storage tank


1


-


212


. Outlet ports

-


214


in the pneumatic manifold


1


-


204


are fitted with couplers or connectors


1


-


216


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

FIGS. 12

and


14


). In exemplary embodiments of the invention, these couplers


1


-


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


1


-


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


1


-


206


includes one or more pressure regulator valves


1


-


220


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


1


-


200


to regulate the pressure of compressed air provided at outlet ports


1


-


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. 6

, the manifold assembly


1


-


202


includes a single pressure gauge


1


-


222


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


1


-


204


.




The manifold assembly

is pneumatically coupled to the air compressor assembly


1


-


200


via a short length of air hose


1


-


224


extending between the inlet port


1


-


226


of the manifold assembly's pressure regulator valve


1


-


220


and the outlet port


1


-


228


of a second pressure regulator assembly


1


-


230


mounted to the compressed air storage tank

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

FIG. 6

, the second pressure regulator assembly


1


-


230


may include a pressure regulator valve


1


-


232


for regulating the pressure of compressed air provided at outlet port


1


-


228


and one or more indicators (pressure gauges


1


-


234


&


1


-


236


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


1


-


202


may be regulated at the air compressor assembly


1


-


200


while the manifold assembly


1


-


202


is being used remotely. Further, the air compressor assembly


1


-


200


may be used independently of manifold assembly


1


-


202


if desired.




Quick-connect coupler devices


1


-


240


&


1


-


242


connect the air hose


1


-


224


to inlet port


1


-


226


and outlet port


1


-


228


allowing the air hose


1


-


224


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


1


-


200


and manifold assembly


1


-


202


when the manifold assembly


1


-


202


is removed from the compressed air storage tank


1


-


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


1


-


226


and air hose


1


-


224


, between air hose


1


-


224


and outlet port


1


-

, air hose


1


-


224


being completely removed.




A latching assembly


1


-


244


may be provided for securing the manifold assembly

is comprised of clamps


1


-


246


&


1


-


248


which may be closed on flanges


1


-


250

1


-


252


formed in the manifold assembly's frame


1


-


208


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


1


-


212


. When opened, the clamps


1


-


246


&


1


-


248


release the flanges


1


-


250


&


1


-


252


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


1


-


212


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


1


-


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. 2 through 7

, 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. 2 through 7

, 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.

,


1


-


450


&


1


-


452


so that the manifold assembly


1


-


314


,


1


-


414


is suspended there between when mounted to the air compressor assembly


1


-


300


,


1


-


400


. For instance, in the exemplary embodiment shown in

FIGS. 8 through 11

, the roll cage


1


-


302


,


1


-


402


may be formed of steel tubing having a generally circular cross-sectional shape. In such an embodiment, the edge portions


1


-


354


,


1


-


356


,


1


-


454


&


1


-


456


of frame


1


-


318


,


1


-


418


may be comprised of channels having a substantially semi-circular cross-section sized to fit over a corresponding cage member


1


-


350


,


1


-


352


,


1


-


450


, and


1


-


452


.




A latching assembly


1


-


358


,


1


-


458


may be provided for securing the manifold assembly


1


-


314


,


1


-


414


to the air compressor assembly's roll cage


1


-


302


,


1


-


402


. Preferably, the latching assembly


1


-


358


,


1


-


458


allows the user to easily remove the manifold assembly


1


-


314


,


1


-


414


from the roll cage


1


-


302


,


1


-


402


for remote use. For example, as shown in

FIGS. 8 and 9

, an exemplary latching assembly


1


-


358


may be comprised of a spring loaded plunger


1


-


360


positioned in each cage member


1


-


350


&


1


-


352


for engaging corresponding apertures


1


-


362


formed in edge portions


1


-


354


&


1


-


356


of frame


1


-


318


. Similarly, a second exemplary latching assembly


1


-


458


, shown in

FIGS. 10 and 11

, may comprise one or more one-quarter turn fasteners


1


-


460


mounted to each cage member


1


-


450


&


1


-


452


and positioned to extend through holes


1


-


462


formed in the edge portions


1


-


454


&


1


-


456


of frame


1


-


418


. It will now be appreciated that the latching assembly


1


-


358


,


1


-


458


may utilize other latching mechanisms for securing the manifold assembly to the roll cage depending on the particular design requirements of the air compressor. Consequently, substitution of alternative latching mechanisms for those specifically described herein by those of skill in the art is anticipated, and such substitution would not depart from the scope and spirit of the present invention as set forth in the appended claims.




Referring now to

FIG. 12

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


1


-


500


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


1


-


502


may utilize an air powered tool


1


-


504


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


1


-


506


, a worker


1


-


502


may utilize air powered tools


1


-


504


for performing tasks such as framing walls within the structure


1


-


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 assembly


1


-


508


, providing a source of compressed air for operating the tool


1


-


504


be located remotely from the worker


1


-


502


. For example, when building a multiple level structure


1


-


506


, the air compressor assembly


1


-


508


may be located in a lower level


1


-


510


of the structure


1


-


506


, while the worker


1


-


502


must perform a task in an upper level or floor


1


-


512


of the structure


1


-


506


. In such applications, the manifold assembly


1


-


514


may be detached from the air compressor assembly


1


-


508


and coupled thereto via an air hose


1


-


516


allowing the manifold assembly


1


-


514


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

FIG. 12

, the upper level


1


-


512


of the structure


1


-


506


. The worker


1


-


502


may then couple the air powered tool


1


-


504


to the manifold assembly


1


-


514


via a second air hose


1


-


518


to provide compressed air for powering the tool


1


-


504


. As discussed in the description of

FIGS. 2 through 11

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


1


-


508


and manifold assembly


1


-


514


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


1


-


504


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

FIG. 12

, the lower level


1


-


510


of the structure


1


-


506


.




Turning now to

FIG. 13

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


1


-


600


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


1


-


602


may be secured to a supporting structure


1


-


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


1


-


600


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


1


-


606


may include a flange


1


-


608


having one or more holes formed therein. Fasteners


1


-


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


1


-


604


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


1


-


602


to the supporting structure


1


-


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 tabletop, a floor, or the ground (see FIG.


12


).




Small knobs or feet


1


-


612


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


1


-


606


prevent direct contact with the frame


1


-


606


and supporting structure


1


-


604


for preventing unnecessary damage to the supporting structure


1


-


604


or manifold assembly


1


-


602


due to contact or rubbing during use. An air hose


1


-


614


is connected to inlet port


1


-


616


of the manifold assembly


1


-


602


for pneumatically coupling the manifold assembly


1


-


602


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


1


-


618


,


1


-


620


,


1


-


622


&


1


-


624


may be connected to outlet ports


1


-


626


,


1


-


628


,


1


-


630


&


1


-


632


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


1


-


602


. A pressure regulator assembly


1


-


634


and indicators such as pressure gauges


1


-


636


&


1


-


638


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


1


-


626


,


1


-


628


,


1


-


630


&


1


-


632


.




Referring now to

FIG. 14

, 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


1


-


700


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


1


-


702


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


1


-


706


. As shown in

FIG. 14

, the first manifold assembly


1


-


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


1


-


700


. A second manifold assembly


1


-


704


is coupled to an outlet port of the first manifold assembly


1


-


702


via an air hose


1


-


708


. The second manifold assembly


1


-


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


1


-


700


. One or more air powered tools


1


-


710


,


1


-


712


,


1


-


714


&


1


-


716


may by pneumatically coupled to either the first manifold assembly


1


-


702


or second manifold assembly


1


-


704


via air hoses


1


-


718


,


1


-


720


,


1


-


722


&


1


-


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 assembly (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. 2 through 14

, the air compressor assembly 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 compressor assemblies 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 assembly and used within the immediate vicinity of the air compressor assembly. 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 assembly. Instead, such terms should be construed as encompassing any use of the manifold assembly while detached from the air compressor assembly regardless of the distance of separation between the manifold assembly and air compressor assembly.




Referring generally now to

FIGS. 15 through 27

, exemplary embodiments of a second aspect of the present invention directed to an air compressor assembly including a lifting handle are shown.




Air compressor assemblies may include an air tank for the storage of compressed air. In portable applications, air compressor assemblies are typically transported with the use of a wheel assembly and a transport handle assembly used to guide the air compressor assembly when utilizing the wheel assembly. However, a typical transport handle assembly is not suited for lifting the air compressor, such as when the air compressor assembly is loaded into a truck, needs to be transported over stairs, is lifted over uneven ground, and the like. Therefore, by supplying lifting handles as a part of the air compressor assembly, the assembly may be more easily lifted.




Referring now to

FIG. 15

, an exemplary embodiment of the present invention is shown wherein an air compressor assembly


2


-


100


includes lifting handles so as to enable the air compressor assembly to be lifted in an easier manner. The air compressor assembly


2


-


100


generally includes an air tank


2


-


102


for the storage of compressed air. Typically, the supply of compressed air is accomplished through the use of a compressor and motor, which may be gasoline, electric, and the like which may be mounted to the air tank


2


-


102


with the use of an engine mount


2


-


104


. A transport handle


2


-


106


may be utilized to control the movement of the air compressor assembly


2


-


100


when utilizing the wheel assemblies


2


-


108


and


2


-


110


. In this way, the air compressor assembly


2


-


100


is capable of portable operation by tilting the base


2


-


112


from the ground thereby permitting the wheel assemblies


2


-


108


and


2


-


110


to proceed. However, the use of transport handles


2


-


106


alone is not well suited for lifting the air compressor assembly


2


-


100


. Therefore, a lifting handle


2


-


116


and


2


-


114


is positioned on each side of the air tank


2


-


102


proximally to the wheel assemblies


2


-


108


and


2


-


110


to enable the air compressor assembly


2


-


100


to be lifted without the necessity of the unsure grasping and wrestling of an air compressor assembly as previously required.




It may also be preferable to include tie-down points


2


-


118


with the lifting handles


2


-


114


and


2


-


116


to secure the air compressor assembly


2


-


100


during transport. For example, an air compressor assembly


2


-


100


is typically not well suited for transport in the back of a truck. During transport, the air compressor assembly


2


-


100


may be subjected to jostling and bumps which may cause the air compressor assembly to move in unwanted and unpredictable ways, such as tipping, sliding, and the like. Thus, by providing tie-down points


2


-


118


, the air compressor assembly


2


-


100


may be secured, thereby preventing damage not only to the air compressor assembly


2


-


100


, but also its surroundings.




Referring now to

FIG. 16

, a side view of the exemplary embodiment of

FIG. 15

is shown. An air compressor assembly


2


-


100


includes an air tank


2


-


102


. The air tank


2


-


102


includes a transport handle


2


-


106


and wheel assembly


2


-


108


for rolling the air compressor assembly


2


-


100


. The air tank


2


-


102


may be defined to include a first end portion


2


-


120


and a second end portion


2


-


122


. Accordingly, in the present example, the first end portion


2


-


120


may include the transport handle


2


-


106


, and the second end portion


2


-


122


may include the wheel assembly


2


-


108


and the lifting handle


2


-


116


. In this way, both the first end portion


2


-


120


and the second end portion


2


-


122


are supported when the air compressor assembly


2


-


100


is lifted. Thus, the breakage and effort previously associated with lifting an air compressor assembly may be greatly diminished.




As shown in

FIG. 17

, lifting handles


2


-


114


and


2


-


116


positioned on an air tank


2


-


102


enable users to lift the air compressor assembly


2


-


100


in an efficient manner. In this example, a user grasps the first lifting handle


2


-


114


and the transport handle from one side while another user grasps the second lifting handle


2


-


116


and the transport handle


2


-


106


to be able to lift the air compressor assembly


2


-


100


in a secure manner. In another example, a user may be positioned on the end of the air compressor assembly to grasp both lifting handles


2


-


114


and


2


-


116


while another user grasps the transport handle


2


-


106


to lift the air compressor assembly


2


-


100


from the ends.




Referring now to

FIG. 18

, an end view of the exemplary embodiment of

FIG. 15

is shown. It may be preferable to include the lifting handles


2


-


114


and


2


-


116


as an integral part of the wheel assemblies


2


-


108


and


2


-


110


to provide an integrated part that may be manufactured and attached in a cost-effective manner. The wheel assemblies


2


-


108


and


2


-


110


may include wheel mounts


2


-


124


and


2


-


126


suitable for attaching wheels


2


-


128


and


2


-


130


, thereby enabling the air compressor assembly


2


-


100


to be rolled. In this example, the wheel assemblies


2


-


108


and


2


-


110


are shown as two separate wheel assemblies


2


-


108


and


2


-


110


, which may be preferable so as to reduce the cost of materials. However, a single wheel assembly may also be utilized which includes two wheels, a single wheel, a plurality of wheels and brackets, and the like without departing from the spirit and scope of the present invention.




It may also be preferable to locate the lift handles


2


-


114


and


2


-


116


below or generally equal to the top edge


2


-


128


of the air tank


2


-


102


. By locating the lifting handles


2


-


114


and


2


-


116


below the top edge of the air tank


2


-


128


, a user may be better able to control the lifting of the air compressor assembly


2


-


100


as well as have an increased lifting range. For example, a user, grasping a transport handle


2


-


106


may not be able to lift the air compressor assembly


2


-


100


as high as with a lower located lifting handle


2


-


114


and


2


-


116


, which may be required when loading the air compressor assembly in the back of a truck, carrying the air compressor assembly over rough terrain, and the like. Thus, the location of the lifting handles


2


-


114


and


2


-


116


below the top edge of the air tank


2


-


102


may enable the air compressor assembly


2


-


100


to be lifted in an improved manner.




Referring now to

FIG. 19

, a top view of the exemplary embodiment of

FIG. 15

is shown. An air compressor assembly


2


-


100


suitable for storing compressed air includes an air tank


2


-


102


. The air tank


2


-


102


includes a front-end portion


2


-


132


, a rearward portion


2


-


134


, a first side portion


2


-


136


, and a second side portion


2


-


138


. Lift handle assemblies


2


-


114


and


2


-


116


, suitable for use in lifting the air compressor assembly


2


-


100


, are at least partially disposed on at least one of the first


2


-


136


and second


2


-


138


side portions. In this way, users positioned at both sides


2


-


136


and


2


-


138


may be able to lift the air compressor assembly


2


-


100


, as shown in FIG.


17


. This may prove especially useful when trying to lift the air compressor assembly


2


-


100


onto a higher surface. For example, users may lift the air compressor assembly


2


-


100


from the side


2


-


136


and


2


-


138


, position the wheels


2


-


128


and


2


-


130


on the surface, and then roll the air compressor assembly


2


-


100


so that the base


2


-


112


is also placed on the surface. Thus, lifting the air compressor assembly


2


-


100


is much easier than the wrestling that was required to lift previous air compressor assemblies.




Lifting handles may take many different forms and be placed at a variety of positions without departing from the spirit and scope of the present invention. For example, as shown in

FIG. 20

in an additional exemplary embodiment of the present invention, a plurality of lifting handles may be placed on the side of an air compressor assembly


2


-


600


. In this example, a second lifting handle


2


-


642


and


2


-


640


is added to each side


2


-


636


and


2


-


638


of the air compressor assembly


2


-


600


. Thus, each side of the air tank


2


-


602


includes a first lifting handle


2


-


616


and


2


-


614


and a second lifting handle


2


-


640


and


2


-


642


to enable a user positioned at a side


2


-


636


and


2


-


638


of the air compressor assembly


2


-


600


to lift the assembly


2


-


600


without having to reach for the transport handle


2


-


606


. This may further enable a user to lift the air assembly in an efficient manner, without causing damage to the air compressor assembly


2


-


600


or injury to the user. For example, the weight and size of an air compressor assembly


2


-


600


may be quite substantial. By enabling a user to lift the air compressor assembly


2


-


600


in a more natural manner, the chances of injury due to over-reaching and the damage that may be caused to the assembly if dropped may be greatly reduced.




Additionally, the lifting handles may extend along the sides of the air compressor assembly, an example of which is shown in

FIG. 21. A

first lifting handle


2


-


714


and a second lifting handle


2


-


716


extend generally along the side of the air compressor assembly


2


-


700


. These handles


2


-


714


and


2


-


716


may be attached to the air tank


2


-


702


and extend generally along the middle section of the air tank to provide an extended gripping region. Thus, multiple users may utilize the lifting handles


2


-


714


and


2


-


716


to lift the air compressor assembly


2


-


700


, which may further prevent injury and damage.




Furthermore, the lifting handles may be formed as an integral part of the base of the air compressor assembly. For example, as shown in

FIG. 22

, an air compressor assembly


2


-


800


may incorporate a wheel assembly


2


-


808


and


2


-


810


with integral lifting handles


2


-


814


and


2


-


816


. A base


2


-


812


of the air compressor assembly may also incorporate lifting handles


2


-


840


and


2


-


842


to provide an additional gripping region. In this way, the handles


2


-


840


and


2


-


842


may be manufactured with the base


2


-


812


, resulting in a cost saving in both production and assembly. Further the additional set of handles


2


-


840


and


2


-


842


provide increased control and ease of use as described in FIG.


20


.




Lifting handles may also be positioned at the end of the air compressor assembly, an example of which is shown in FIG.


23


. The air tank


2


-


902


may include a first end portion


2


-


920


and a second end portion


2


-


922


. The first end portion


2


-


920


may include the transport handle


2


-


906


and the second end portion


2


-


922


may include the wheel assembly


2


-


908


,


2


-


910


and a first lifting handle


2


-


914


and a second lifting handle


2


-


916


. Thus, both the first end portion


2


-


920


and the second end portion


2


-


922


are supported when the air compressor assembly


2


-

Referring generally now to

FIGS. 42 through 48

, exemplary embodiments of a fourth aspect of the present invention directed to a novel apparatus for protecting the condensate removal device from damage caused by contact with foreign objects are shown.




Referring to

FIGS. 42A and 42B

, an exemplary compressed air tank


4


-


100


known to the art is shown. Compressed air tanks


4


-


100


typically comprise an air tank


4


-


110


and a tank drain valve


4


-


115


. A tank drain valve


4


-


115


may be connected to an air tank


4


-


110


via a mounting assembly


4


-


120


. The mounting assembly may include a weld flange


4


-


170


(

FIG. 42C

) and a plug


4


-


160


(

FIG. 42C

) that is capable of being threaded within the weld flange


4


-


170


(FIG.


42


C). The tank drain valve


4


-


115


may be threaded to allow the valve


4


-


115


mounted within the mounting assembly


4


-


120


.




Referring specifically to

FIG. 42C

, a detailed view of a mounting assembly for a valve is shown. The weld flange


4


-


170


is welded to the air tank


4


-


150


. A mounting device


4


-


160


may be threaded and placed within the weld flange


4


-


170


. This type of mounting assembly allows for a greater opening in the tank


4


-


150


as required per ASME standards for some types of compressed air tanks


4


-


100


. By removing the valve


4


-


140


, an inspection of the inside of air tank


4


-


150


may be more easily accomplished. Drain valves known to the art project a great distance away from the air tank. This leaves the drain valves exposed to possible damage as a result of contact with foreign objects.




Referring to

FIGS. 43A and 43B

, an exemplary embodiment


4


-


200


of a condensate removal protection apparatus of the present invention is shown. A condensate removal device may be mounted to an air tank (not shown) at a low point of the air tank in order to remove condensate from the air tank. As shown in

FIGS. 43 through 48

, the condensate removal device is a valve


4


-


210


. However, the present invention is not limited to valves. Any condensate removal device that allows ease in opening and closing a removable closure and may maintain a constant pressure inside the tank when the removable closure is closed may be utilized without departing from the scope and spirit of the present invention. Further, different types of mounting assemblies may be incorporated with the present invention to a person of ordinary skill in the art and thus various types of mounting assemblies may be incorporated with the present invention without departing from the scope and spirit of the present invention. An example of a condensate removal device is a plug. A plug may be utilized yet is not recommended because it does provide the necessary ease in removing and replacing the plug when draining is necessary. Typically, manufacturers recommend that a compressed air assembly be drained at least once a day to prevent against corrosion on the inside of the air tank. Thus, ease in opening and closing the removal device is paramount. Further, different types of mounting assemblies may be incorporated with the present invention to a person of ordinary skill in the art and thus various types of mounting assemblies may be incorporated with the present invention without departing from the scope and spirit of the present invention.




Referring specifically to

FIGS. 43A and 43B

, in an exemplary embodiment two I-shaped support pieces


4


-


220


may be placed on opposite sides of the valve


4


-


210


to prevent the valve


4


-


210


from coming into contact with any foreign objects. The valve


4


-


210


may be connected to a mounting assembly


4


-


215


that connects the valve


4


-


210


to an air tank. The exemplary support pieces as shown in

FIGS. 43 through 45

may be manufactured from any strong and durable material including metal, plastic, fiberglass, and wood. For ease in manufacturing, a preferred material for the support may be metal as it may be easily welded to an air tank. Foreign objects may include but are not limited to mud, dirt, rocks, tools, equipment, concrete, wood, and hose. Along with providing a shield against contact with foreign objects, the condensate removal protection apparatus


4


-


200


provides room to allow access by tools or hands in order to open and close the valve


4


-


210


.




Alternate embodiments may be utilized in order to protect a condensate removal device from coming into contact with foreign objects. Referring now to

FIGS. 44A and 44B

, an alternative exemplary embodiment


4


-


300


of the condensate removal protection apparatus of the present invention is shown. Surrounding the valve


4


-


310


and the mounting assembly


4


-


315


, a cylindrical support


4


-


320


may be mounted to an air tank. This may allow coverage on all sides of the drain valve


4


-


310


and the mounting assembly


4


-


315


, however, an opening is present to allow access to the valve


4


-


310


for draining of condensate from an air tank. It should be noted that a shape that is not cylindrical that surrounds the valve including but not limited to square, rectangular, trapezoidal may be recognized and utilized by a person with ordinary skill in the art without departing from the scope and spirit of the present invention.




Additionally, a cap may be placed on the bottom of the cylindrical support


4320


to protect the valve from contact from any direction. Referring to

FIGS. 45A and 45B

, in an exemplary embodiment


4


-


400


a cylindrical support


4


-


420


surrounding a valve


4


-


410


and a mounting assembly


4


-


415


may be threaded to allow a cap


4


-


430


to be connected to the cylindrical support


4


-


420


. The advantage of this embodiment is that the valve


4


-


410


may be completely enclosed within a protective apparatus, however, a cap


4


-


430


must be removed when draining is to take place. The cap


4


-


430


may be fitted with an extension


4


-


440


on the outer end of the cap to allow easier access to opening the cap


4


-


430


. Once again, a shape that is not cylindrical and a cap formed to fit over the shape of the support may be utilized without departing from the scope and spirit of the present invention.




Turning to an alternative way of protecting a valve from contact from foreign




Turning to an alternative way of protecting a valve from contact from foreign objects, in an exemplary embodiment


4


-


500


of the present invention a valve may be recessed within the mounting assembly as shown in

FIGS. 46A and 46B

. Referring specifically to

FIG. 46A

, an air tank


4


-


510


is shown comprising a valve


4


-


520


connected to a threaded plug


4


-


530


. The plug


4


-


530


may be secured to the tank via a weld flange


4


-


525


that may be welded to an air tank


4


-


510


. In this embodiment, the plug


4


-


530


may be thought of as a reducer as it covers a larger hole in the air tank


4


-


510


and reduces the hole to one that may fit the valve


4


-


520


. The plug


4


-


530


provides a number of advantages. First, it provides a good seal to ensure pressurization within the air tank


4


-


510


. Also, it allows for an easier inspection as dictated per ASME standards for some compressed air tanks. Further, by recessing the valve


4


-


520


within the plug


4


-


530


, the valve


4


-


520


may be protected from contact with foreign objects. Yet there is enough space to allow access to the valve


4


-


520


by a user to open and close the valve


4


-


520


. The plug


4


-


530


may be threaded to allow easy installation and removal from the tank via a threaded weld flange


4


-


525


. As shown in

FIG. 46B

, the outer end of the valve


4


-


520


may protrude outside of the mounting


4


-


530


. It should also be noted that protective supports as shown in

FIGS. 43 through 45

may also be incorporated with the recessed valve embodiment to ensure greater protection from contact from foreign objects. Thus, for example, a recessed valve may be utilized in conjunction with two I-shaped supports in proximity of the valve to further protect the valve from contact with foreign objects. Also, it should be recognized that the plug


4


-


530


as shown in

FIGS. 46A and 46B

are exemplary only and various modifications may be made to the mounting device to allow recessing of the valve


4


-


520


within the mounting device


4


-


530


by one of ordinary skill in the art without departing from the scope and spirit of the present invention.




Referring now to

FIG. 47

, the placement of the condensate removal device need not be in the center of the air tank. For example, in exemplary embodiments


4


-


600


the condensate removal device may be placed near the bracket


4


-


620


, in the middle


4


-


630


, and near the wheels


4


-


640


along with areas in between the front and end of the air tank


4


-


650


. Also, it should be noted that the present invention is not limited to a single style of air tank as the condensate removal protection apparatus may be utilized in all types of air tanks. An exemplary middle location


4


-


630


may be preferred as inspections made on the air tank may be made easier with a hole located in the center of the air tank on the bottom side and a hole in the center of the air tank on the top side. Typically, a check valve may be placed in the center of the air tank on the top side. With these two locations, a thorough inspection of the inside of air tank is possible to check for wear and corrosion. In all of the locations regarding placement of the condensate removal device, exemplary supports as shown in

FIGS. 43 through 45

may be incorporated with the condensate removal device.




Further, in another exemplary embodiment


4


-


700


, the condensate removal device


4


-


710


may be attached to a tube


4


-


720


that is connected to an air tank


4


-


730


as shown in FIG.


48


A. This may reduce the distance that the condensate removal device


4


-


710


protrudes outwardly from the air tank


4


-


730


. In another exemplary embodiment


4


-


750


, the condensate removal device


4


-


760


may be placed on a side of an air tank


4


-


770


. As shown in

FIG. 48B

, the condensate removal device may be placed on a side close to the wheels


4


-


780


. In order to remove condensate from an air tank


4


-


770


, lifting of the front of the air tank


4


-


770


may be required. Different embodiments may be available to a person with ordinary skill in the art in order to protect a condensate removal device from contact from foreign objects that do not depart from the scope and spirit of the present invention.




Referring generally now to

FIGS. 49 through 52

, exemplary embodiments of a fifth aspect of the present invention directed to a portable air compressor assembly of the type having a horizontal compressed air storage tank are shown.




Referring generally to

FIGS. 49 through 52

, a portable air compressor assembly in accordance with an exemplary embodiment of the present invention is described. The portable air compressor assembly


5


-


200


includes a compressor


5


-


202


mounted to a horizontal compressed air storage tank


5


-


204


, often referred to in the art as a “hot-dog” style air tank. The compressed air storage tank


5


-


204


provides a tank or receiver for storing air under pressure. A pressure manifold assembly


5


-


206


is fitted to the compressed air storage tank


5


-


204


allowing compressed air to be drawn from the tank


5


-


204


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. In exemplary embodiments, a pressure switch assembly


5


-


208


is mounted to the pressure manifold assembly


5


-


206


for regulating pressure within the compressed air storage tank


5


-


204


by alternately starting and stopping the compressor


5


-


202


to periodically replenish the supply of air in the tank


5


-


204


. Typically, when pressure within the tank


5


-


204


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


5


-


208


starts the compressor


5


-


202


to re-pressurize the tank


5


-


204


. As the pressure within the tank


5


-


204


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


5


-


208


stops the compressor


5


-


202


to prevent over-pressurization of the tank


5


-


204


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


5


-


204


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




The air compressor assembly


5


-


200


further includes a wheel assembly


5


-


210


mounted to a first end portion


5


-


212


of the compressed air storage tank


5


-


204


. In an exemplary embodiment, the wheel assembly


5


-


210


includes a wheel


5


-


214


mounted to each side of the air storage tank


5


-


204


by a wheel bracket


5


-


216


. A handle assembly


5


-


218


is mounted to a second end portion


5


-


220


of the compressed air supply tank


5


-


204


opposite the wheel assembly


5


-


210


by a handle bracket


5


-


222


. The handle assembly


5


-


218


allows the air compressor assembly


5


-


200


to be transported by lifting upward on handles


5


-


224


and pushing the air compressor assembly


5


-


200


much like a common wheelbarrow.




A base


5


-


226


is mounted to the bottom of the horizontal compressed air storage tank


5


-


204


adjacent to the second end portion


5


-


220


, e.g., opposite the wheel assembly


5


-


210


. In an exemplary embodiment, the base


5


-


226


includes a bottom member


5


-


228


and distal side members


5


-


230


&


5


-


232


. Preferably, side members


5


-


230


&


5


-


232


are joined at the outer ends of bottom member


5


-


228


and extend upward therefrom. The side members


5


-


230


&


5


-


232


are terminated at their upper end by tank attachment members


5


-


234


&


5


-


236


which are angled to provide a surface for attachment of the base


5


-


226


to the bottom surface


5


-


238


of the horizontal compressed air storage tank


5


-


204


via a suitable attachment method such as welding, or the like. Feet


5


-


240


, formed of plastic, rubber or like material, are attached to the bottom member


5


-


228


. The feet


5


-


240


prevent the bottom member


5


-


228


from directly contacting floor surfaces on which the air compressor assembly


5


-


200


may rest so that the base


5


-


226


does not damage (e.g., scratch, gouge, or mar) such surfaces.




In one embodiment of the present invention, the lower portion of base


5


-


226


, e.g., bottom member


5


-


228


, has a width (“w”) at least substantially as wide as the outer diameter of the compressed air storage tank


5


-


204


. The base


5


-


226


thus provides increased resistance to tipping as a result of external forces exerted on the compressed air storage tank


5


-


204


or compressor


5


-


202


, for example, by a user or vehicle inadvertently bumping into the side of the air compressor, by a user pulling or jerking an air hose coupled to the air compressor's pressure manifold assembly


5


-


206


, or the like. In this manner, the base


5


-


226


provides increased stability to the air compressor assembly


5


-


200


, especially in austere environments.




As shown in

FIG. 50

, side members


5


-


230


&


5


-


232


may angle inwardly from the bottom member


5


-


228


so that attachment members


5


-


234


&


5


-


236


join the bottom surface of the compressed air storage tank


5


-


204


. In this manner, the attachment between the base


5


-


226


and compressed air storage tank


5


-


204


is made more robust than would be possible if the side members


5


-


230


&


5


-


232


were attached to the sides of the tank


5


-


204


since the welds between the attachment members


5


-


234


&


5


-


236


and tank are subjected to lower shear stress. In the exemplary embodiment illustrated and described herein, the base


5


-


226


is shown as having a straight, single piece bottom member


5


-


228


and angled side members


5


-


230


and


5


-


232


. However, it will be appreciated that the shape of base


5


-


226


is not limited to a specific geometry. For example, the base


5


-


226


may be provided with additional members extending between the bottom member


5


-


228


and the bottom surface


5


-


238


of the compressed air storage tank


5


-


204


, or may be formed from a solid plate.




In another embodiment of the present invention shown in

FIG. 51

, tie-down points may be provided for securing the air compressor assembly


5


-


200


to a platform such as a floor surface, the bed and/or sidewalls of a truck, a trailer, a lift, or the like. In an exemplary embodiment, each wheel bracket


5


-


216


may include a handle assembly


5


-


242


providing a point by which a user may lift the air compressor assembly


5


-


200


. The handle assembly


5


-


242


includes an upper surface


5


-


244


having one or more apertures


5


-


246


(

FIG. 52

) formed therein. Similarly, the handle assembly mounting bracket


5


-


222


may include one or more additional apertures


5


-


248


&


5


-


250


(FIG.


52


). Preferably, these apertures


5


-


246


,


5


-


248


&


5


-


250


are sized to allow attachment of a rope, cable, cord, or the like thereby providing tide down points for securing the portable air compressor assembly


5


-


200


to the platform.




In a further embodiment shown in

FIG. 52

, the side members


5


-


230


&


5


-


232


of base


5


-


226


may be extended upward along the sides of the air storage tank


5


-


204


to support a second set of handle assemblies


5


-


252


which may be used in cooperation with handle assemblies


5


-


242


to lift the air compressor assembly


5


-


200


. Like the handle assemblies


5


-


242


provided by wheel brackets


5


-


216


, handle assemblies


5


-


252


include an upper surface


5


-


254


having one or more apertures


5


-


256


formed therein providing additional tie-down points for the portable air compressor


5


-


200


.




In view of the discussion of FIG.


1


and

FIGS. 49 through 52

, it will now be apparent to those of skill in the art that tie-down points may be provided elsewhere on the air compressor. For example, additional tie-down points may be furnished in brackets provided for mounting such components as the compressor


5


-


202


, pressure manifold assembly


5


-


206


, and pressure switch assembly


5


-


208


. Accordingly, provision of such tie-down points by one of ordinary skill in the art would not depart from the scope and spirit of the present invention as defined in the appended claims.




It is believed that the air compressor assembly of the present invention and many of its attendant advantages will be understood by the foregoing 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.
