- the present invention relates generally to the field of pumps for inflatable objects such as air mattresses and chairs. More specifically, the present invention relates to a pump for inflatable objects that includes an integrated light source.
- Air pumps are commonly used on camping trips to inflate items such as chairs and air mattresses. Typically, such air pumps are battery powered and tend to be heavy, due to the weight of the batteries. For example, an air pump could require four D-cell batteries in order to provide enough power to inflate an object at a reasonable rate.
- Couplings that connect the pump to the inflatable object often need to be mated carefully to avoid leaks, and during situations where inflation is required, it may be dark and difficult to properly mate the pump with the inflatable object.
- a solution to this problem is to provide an air pump that can inflate various inflatable objects and also includes a light source. Furthermore, since air pumps are commonly used on camping trips where light can be scarce, it is also desirable to integrate a light source positioned such that a user could illuminate the valve on the inflatable object during inflation or deflation.

FIG. 1 is a perspective view of a pump embodiment. Thepump 10 includes ahousing 12 with afirst end 14 and asecond end 16. Thehousing 12 contains the inner workings of a common pump for the inflation of an inflatable object, such as a motor 46 (shown inFIG. 3 ) and an impeller (not shown). The construction of a typical handheld pump is described, for example, in commonly owned U.S. Pat. No. 5,890,822 to Robert M. Feldman which is herein incorporated by reference. Furthermore, thehousing 12 includes anair inlet 18 defined on thefirst end 14 of thehousing 12 and anair outlet 20 defined on theside 22 of thehousing 12. The illustrated embodiment also includes ahandle portion 24. - The pump embodiment also includes an integrated
lamp assembly 26 defined on thehandle portion 24. Thelamp assembly 26 includes alens 28, an array of light emitting diodes 30 (LEDs) andcorresponding reflectors 32. Additionally, referring toFIGS. 2 and 3 , the pump embodiment includes abattery compartment 34 capable of holding one ormore batteries 40 to supply themotor 46 with power. Alternatively, thehousing 12 could include a connection for an external power source. The pump embodiment also includes afirst switch assembly 36, and may also include asecond switch assembly 38 for controlling the motor of thepump 10 and/or theLEDs 30. - The present invention provides a single unit that can inflate and/or deflate an inflatable object and function as a flashlight. In operation, a user connects the
air outlet 20 of thepump 10 to a valve on an inflatable object such as the valve disclosed in U.S. Pat. No. 5,367,726 to Robert B. Chaffee, which is herein incorporated by reference. Alternatively, thepump 10 can be attached to any air inlet on an inflatable object utilizing universal adaptors such as those disclosed in commonly owned U.S. Pat. No. 5,890,882 to Robert M. Feldman, which is herein incorporated by reference. Thepump 10 attaches to the valve at theair outlet 20 defined on the side of thehousing 12. Thefirst switch assembly 36 is actuated to energize themotor 46 which drives the impeller (not shown). The rotation of the impeller draws air through theair inlet 18 defined on thefirst end 14 of thehousing 12, routes it through the interior of thehousing 12 and out through theair outlet 20 into the inflatable object. Thefirst switch assembly 36 is then actuated to deactivate themotor 46 and stop further inflation. - The
pump 10, in an alternative embodiment, could also be used to deflate an inflatable object. In the deflation configuration, theair inlet 18 of thepump 10 is attached to the valve of the inflatable object, and thefirst switch assembly 36 is activated. Air is drawn out of the inflatable object through theair inlet 18 of thepump 10, routed through the interior of thehousing 12 and out through theair outlet 20 into the atmosphere. Alternatively, themotor 46 could be reversible so that it could drive the impeller in the opposite direction, allowing both inflation and deflation from one configuration. - In an alternative embodiment, the
air outlet 20 can include a sensor that senses when the pump is connected to a valve such as the sensing arrangement described in U.S. Pat. No. 5,263,363 to Robert B. Chaffee, which is herein incorporated by reference. Such a sensing arrangement could comprise a lever combined with electrical contacts. Upon connection to the valve of the inflatable object, the lever is biased into a position where it completes a circuit and activates themotor 46. This allows auto-activation of themotor 46 when theair outlet 20 is connected to a valve of the inflatable object. In this embodiment, only afirst switch assembly 36 is required, and thefirst switch assembly 36 allows a user to turn theLEDs 30 on or off. - The integrated
lamp assembly 26 is preferably disposed on thehousing 12 on or near thehandle portion 24 as shown in the illustrated embodiments. This allows the user to comfortably hold thepump 10 in one hand and direct it like a traditional flashlight. Alternatively, the integratedlamp assembly 26 may be molded directly into thehousing 12. The integratedlamp assembly 26 preferably includes at least oneLED 30, alens 28 and areflector 32. In the illustrated embodiments, an array of threeLEDs 30 is provided, each with acorresponding reflector 32. In operation, a user actuates asecond switch 38 to energize theLEDs 30. Light emitted from the LEDs is reflected by thereflectors 32 out through thelens 28. A typical lamp assembly incorporating LEDs and the necessary circuitry is disclosed in U.S. Pat. No. 7,309,147 to Richard W. Martin, which is herein incorporated by reference, but any suitable lamp assembly known in the art could be used in the present invention, including incandescent or fluorescent bulbs and associated circuitry to provide power and switchability thereto. Thereflectors 32 may be constructed from any suitable reflective material such as plastic with reflective coating, or polished aluminum. Other reflective materials may also be used. Furthermore, whilewhite LEDs 30 are preferred because of their high luminescence, other colored LEDs could also be incorporated. Moreover, asingle LED 30 could be used, or the LED array could include any number ofLEDs 30. - The
pump 10 of the present invention may be powered by any means commonly known in the art. As shown inFIG. 3 , four D-cell batteries 40 located in thebattery compartment 42 of thehousing 12 power the pump. Depending on the power requirements of themotor 46 and theLEDs 30, larger or smaller numbers of batteries could be utilized. One set ofbatteries 40 could power both themotor 46 and theLEDs 30, or one set of batteries could provide power for themotor 46 while a second set of batteries provides power to theLEDs 30. Alternatively, thepump 10 could be a rechargeable AC/DC pump, such as that disclosed in commonly owned U.S. Patent Publication No. 2007/0077153 to Timothy F. Austen et al., which is herein incorporated by reference. The circuit disclosed in the Austen publication could be adjusted to also power theLEDs 30. - In an alternative embodiment shown in
FIG. 4 , asecond lamp assembly 44 is integrated into theside 22 of thehousing 12 proximate theair inlet 18. Thesecond lamp assembly 44 comprises at least oneLED 30, alens 28 andreflectors 32, constructed in the same fashion as the previously describedlamp assembly 26. The positioning of thesecond lamp assembly 44 proximate theair inlet 18 provides illumination of an inlet port of an inflatable object in low light situations. TheLEDs 30 of thesecond lamp assembly 44 can be activated by a user through the actuation of thefirst switch assembly 36, or through the actuation of a third switch assembly (not pictured). - Also, the
lamp assembly 26 can have a power source that is separable and detachable from the pump, with an area on thehousing 12 that would allow for attachment of thelamp assembly 26. - Alternatively, as shown in
FIG. 5 , in an embodiment where threeLEDs 30 are shown, the two mostlateral LEDs 30,lens 28, andreflectors 32 on thelamp assembly 26 may be positioned at an angle relative to themedial LED 30,lens 28, andreflector 32 such that the spectrum of light emitted by the lamp assembly is broader than the lamp assembly shown inFIG. 4 . - In
FIG. 6 , thelamp assembly 26 is shown withLED 30,lens 28, andreflector 32. Cut-out 48 may be integrated into the lamp assembly such that light from thelamp assembly 26 may be emitted to the side of thepump 10. The cut-out 48 may be a clear piece of plastic or configured in a way such that light may be emitted in a first direction to the front of thepump 10 and in a second direction to the side of thepump 10. - In yet another embodiment, the
lamp assembly 26 could be mounted on a swivel (not shown), a ball joint (not shown), or a flexible gooseneck (not shown) which is in turn mounted on thehousing 12. This would allow for independent movement of thelamp assembly 26. - It should be noted that there could be a wide range of changes made to the present embodiments without departing from the scope of the claimed invention. The
first lamp assembly 26 could be repositioned to thesecond end 16 of thehousing 12, or any other location on thehousing 12. It is therefore intended that the foregoing detailed description be regarded as illustrative rather than limiting, and that it be understood that it is the following claims, including all equivalents, that are intended to define the spirit and scope of this invention.
