DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved portable beverage dispenser embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, it will be noted that the first embodiment 10 of the invention includes a beverage dispenser with housing 12 containing two tanks 24 and 28. Liquids stored within tanks 24 and 28 may be electrically heated or cooled. Tanks 24 and 28 are divided by insulated partition 40. Beverages are poured into the tanks through openings covered by removable lids 26 and 30. Dispenser hand pump 32 allows manual pressurization of tank 28. A similar hand pump exists for tank 24 as well. Dispensing taps 16 and 18 regulate the flow of liquids through an outlet from tanks 24 and 28, respectively. Switch 74 may be utilized to select cool, heat, or off positions for respectively actuating a cooling or heating element in tank 28, or to leave tank 28 at ambient temperature. Switch 76 shown in FIGS. 2 and 6 similarly controls the temperature of tank 24. Cigarette lighter 20 fits into lighter socket 22 for activation in a conventional manner.

The front wall of the housing contains a recess 44 large enough to receive a small radio. Handle 42 is connected to the housing by flange 48 which is retained by housing flange 50 in such a manner as to enable handle 42 to slide up and down along the housing front wall for the length of recess 44.

A lid 14 hinged to the rear housing wall covers the dispenser. Lid 14 is padded for use as a seat when closed. Four corner leg wells 46 house extension legs 51 as shown in FIG. 7.

Returning to FIG. 1, mounting skirt 66 is comprised of a top plate 52 with key hole shaped eye holes 54 designed to releasably engage skirt mounting pegs 56 attached to the housing bottom of dispenser 10. Engaging pegs 56 within eye holes 54 mounts dispenser 10 onto mounting skirt 66. Side plates 62 and 64 are attached to top plate 52 by hinges 58 and 60, respectively. The hinges 58 and 60 are spring biased in a manner causing the side plates to close towards each other so as to hug the transmission hump of an automobile. For example, spring biased hinge 60 urges side plate 64 towards the position shown as 64'.

Connecting wire 34 has plug endings 36 and 38 for connection between an automobile lighter socket and dispenser socket 29, shown in FIG. 5.

FIG. 2 is a top view of the dispenser with the cushioned lid 14 closed.

FIG. 3 is a side view of the dispenser showing openings 19 for the speaker 15 shown in FIG. 6. Similar openings are provided on the opposite side of the dispenser for speaker 17.

FIG. 4, a front view of the dispenser, shows handle 42 slid to an upper position.

FIG. 5 is a rear view of the dispenser showing hinge 13 joining lid 14 to the back of housing 12. Dispenser socket 29 is configured for engagement with one end of plug 34, for tapping the electrical system of a vehicle through a conventional vehicle cigarette lighter socket.

FIG. 6, a top sectional view of the dispenser, clearly illustrates the heating and cooling mechanisms of the tanks 24 and 28. Heating tubes 41 and 47 heat tanks 24 and 28, respectively. The heating tubes are each connected, independently, to their respective, adjacent, electrical heating elements 39. Cooling tubes 43 and 45 cool tanks 24 and 28, respectively. The cooling tubes are independently connected to their respective, adjacent, thermoelectric cooling elements and batteries 37. Thermoelectric cooling elements and batteries 37 may be of conventional construction, as shown in U.S. Pat. No. 4,384,512, the disclosure of which is hereby incorporated by reference.

Hand pumps 32 and 35 independently pressurize reservoirs 31 and 33, which, in turn, charge liquids in tanks 28 and 24 with pressure against beverage taps 18 and 16, respectively.

Handle 42 is shown alternatively in the retracted and extended positions 42', the latter resulting from handle flange 48 engaging housing flange 50 on two sides. Within the recess 44 (FIG. 1) is shown radio 21, suitably plugged into the dispenser's independent power source through outlet 75 shown in FIG. 7. The radio is connected for driving speakers 15 and 17, when received within the recess 44, as shown in FIG. 12.

Legs 51 are shown in FIGS. 6 and 7. Each of the four legs 51 can slide in and out of leg wells 46. Retaining pin 49 is biased outwardly by spring 55 and is designed to engage housing hole 57 when in the leg is in the extended position outside of leg well 46 and housing hole 59 when the leg is in the retracted position within leg well 46. Guide runner 70 slides along track 71 and limits leg extension in a manner such that the top of leg 51 will not slip out of leg well 46.

FIGS. 8-11 illustrate the mounting skirt. Particularly, they show gripping projections 63 which are adapted to grip the carpet around the transmission hump, thus more securely mounting the dispenser within a vehicle.

FIG. 12 shows a schematic diagram of the wiring. A power source, such as a car battery, may be connected to rechargeable battery 37 using plug 34 plugged into a standard automobile socket at one end and dispenser socket 29 at the other end. Wiring then exists connecting rechargeable battery 37, which includes a switching controller, to cigarette lighter socket 22, radio plug 75, and switches 74 and 76. Switches 74 and 76 may be switched to supply power to the heating elements 47 and 41, respectively, or to the cooling elements 45 and 43, respectively, or to an off position.

Note that the wiring permits fully independent storage temperatures in the separate tanks so that, for example, either one may be heated while the other is cooled. Note also that the radio is fully separable from the circuitry so that it may either be played apart from the dispenser, or attached within housing recess 44, and utilized either with earphones 80, or connected to speakers 15 and 17.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
