DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

[0028] Referring now to FIG. 1 we see a perspective view of the ice-cream vending machine of the present invention. The invention consists of an upper half 4 and a lower half 2. The lower half includes an insulated, refrigerated housing which stores stacks of ice-cream. The upper half stores granular toppings 10 in a plurality of radially disposed bins and liquid toppings 12 in an upper row of radially disposed containers. The upper half 4 can also be refrigerated to keep contents cool and fresh. The front surface of the housing 16, 8 is made of transparent material such as acrylic or glass so that the user can view both the toppings and the mechanism 18 that delivers the toppings. A microprocessor controlled panel 22 allows the user to select his or her choice of ice-cream and toppings. A credit card slot 90 allows the user to pay by credit card transaction, however other standard methods of payment may also be employed including smart phone applications that can remember the user's favorite ice-cream and topping combinations. A centrally located tube 88 stores stacked ice-cream cups 14. A cup is drawn down via telescoping suction cup 40, 44 shown in FIG. 2 and placed in a central location so that it is equally accessible to all toppings 10, 12. Topping delivery arm 18 travels in a radial path 52 and stops at each selected topping 10. The telescoping arm of the delivery mechanism delivers the topping to the ice-cream cup 20. The cup 20 revolves slowly so that the topping can be evenly distributed over the ice-cream contained within the cup 20. Each ice-cream portion is delivered from an opening 6 in the bottom half 2 cover plate. The entire housing is air tight thereby eliminating the chance of the entrance foreign objects such as dirt or insects. Door handle 92 allows the user to open a portion of the housing to retrieve his or her ice-cream and topping contained within ice-cream cup 20.

[0029] FIG. 2 is a side section view which vertically bisects the invention. Upper housing half 4 includes granular storage bins 10 and liquid storage container 12. The granular material can be dispensed in a portioned amount by portion control mechanism 24, which drops a single portion into delivery cup 26. Telescoping arm 18 extends the cup 26 to the central ice-cream holding area and delivers it to the top of the ice-cream located at the epicenter of the unit. Liquid toppings 12 are pumped to the delivery area via a peristaltic pump 30 and delivery tube 32 to the area just above cup 20. Ice-cream cups 14 are stacked in tube 88. The lower most cup can be pulled down when a suction cup 44 on telescoping arm 40 attaches to the bottom of the cup to draw it down to sit on top of round plate 48. Round plate 48 is capable of rotating so that when a topping is dispensed, it is evenly distributed over the ice-cream. The lower housing 2 contains stacks of ice-cream 34. The ice-cream 34 is segmented into portions so that they can be delivered one at a time. Platforms 36 are motorized 38 to allow any one of the stacks to rotate into place for use. The upper housing half 4 preferably is refrigerated to keep the topping ingredients cool and fresh.

[0030] FIG. 3 is a sectioned top view of the top half 4 of the housing. Radially disposed bins 10 can be seen as well as the radial track 52 shown in dotted lines that allows the delivery arm 18 to access all bins. Apertures 6 allow ice-cream portions 34 to be accessed from the bottom half 2 of the housing. Central cup holder tube 88 holds stacked cups 14.

[0031] FIG. 4 is a sectioned view of the lower half 2 of the housing. The entire lower half is insulated 54 thereby allowing freezing air generated by compressor and coil unit 56 to stay cool efficiently. Four ice-cream holding platforms 36 can be seen, each holding four stacks of ice-cream 34. Each platform is capable of rotating so that one of the four stacks of ice-cream 34 can be accessed through apertures 6.

[0032] FIG. 5 is a partial section view of the interior workings of the lower housing 2 and the upper housing 4. Each ice-cream portion 34 includes a centrally located aperture to allow a lead screw 58 to reside through all the portions 34. A motor 62 drives the lead screw 58 causing bottom plate 60 to rise. When one portion 34 of ice-cream rises above aperture 6 the plate 60 stops allowing the ice-cream transfer mechanism 70 to grab the ice-cream portion 34 and place it 34A in cup 14. Partition panels 68 separate each ice-cream portion 34. Telescoping arm 64 engages a hook portion 66 on partition panel 68 and pulls it away from the stack, allowing it to fall into receptacle 42. cup support panel 48 is caused to rotate via gear motor 76 insuring that the toppings are sprinkled evenly over the ice-cream 34A. In the top half, telescoping delivery arm 18 can be seen with its cup 26 ready to accept granular material 72 as it is dispensed in a portioned fashion via portion control mechanism 28 powered by gear motor 74. The delivery cup 26A shown in dotted lines has been flipped upside down to sprinkle its contents into cup 14 and ice-cream 34A. The telescoping arm 18 can travel in a radial track 29 via vertical support member 28.

[0033] The cylindrical open space in the center of the ice-cream portion 34 also allows toppings to enter the space so that the topping is more evenly distributed throughout the final ice-cream and topping product. Additional depressions may also be molded into the top of the ice-cream portion 34 to further increase the even distribution of toppings.

[0034] FIG. 6 is a perspective view of the ice-cream delivery mechanism 70. A pair of arms 102, 104 grip the ice-cream portion 34. The arms 102, 104 start in an outward position as shown by dotted lines 82 and then rotate inward via motorized joints 80 to firmly grip the ice-cream 34. A gear motor 78 then picks up the ice-cream portion 34 and delivers it into cup 14 as shown in FIG. 7. To ensure that the ice-cream portion below the one selected is not accidentally lifted, a solenoid shaft 84 enters aperture 86, as shown in FIG. 7 and penetrates the lower ice-cream portion, thereby insuring that it is not accidentally lifted.

[0035] In an alternate embodiment, the ice-cream stacks are continuous columns of ice-cream, and the ice-cream delivery system includes a heated spatula that slides into the side of the column at the location of a single portion, and then lifts the portion and delivers it into cup 14.

[0036] It should be noted that the ice-cream delivery system can deliver multiple portions of ice-cream 34 into cup 14 depending on what the user selects.

[0037] FIG. 8 is a partial section view of a second embodiment of the invention. In this embodiment the portions of ice cream 208 are retained in cups 212 and include lids 210. The cups 212 are stacked on top of each other and are lifted by motorized lifting plate 206 which rises via motorized timing belt assembly 202, 204. The ice cream portions 208 include cavities 226 that can retain ice cream toppings delivered by scoop 26 and extension arm 18 as described in the first embodiment of the invention.

[0038] Lifting arm 222 engages the return portion of lid 210 and can lift the lid by retracting piston arm 220 and rotating arm joint 224 as shown in FIG. 9. This allows the lid to be dropped into receptacle 214 for future disposal or recycling. This second embodiment eliminates the need to physically transport the ice cream portion from its stacked condition into an empty cup.

[0039] In another embodiment of the inventionmultiple ice cream dispensing assemblies as described above are placed in line and mounted in a mobile food truck type vehicle so that people can have access to the present invention and to the ice-cream it serves in a variety of locations around town. Because the invention provides automatic delivery of ice-cream, multiple users can have access to ice-cream at the same time.

[0040] The invention provides an entertaining and exciting way for a person to access to ice-cream and toppings of his or her choice without need of human assistance.

[0041] While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
