DESCRIPTION OF THE PREFERRED EMBODIMENT:

The continuous racing toy of the present invention is designated generally by thereference numeral 10 in FIG. 1 and consists ofa centrally located trackway section 12 consisting of four distinct racing paths l4, 14, 14' and 14", as illustrated in FIG. 2. At one end of the racing toy is located a first turn-around portion desig- 0 nated generally by thereference numeral 16 within which a propulsion unit is located, as will be discussed in detail hereinafter. Thereference numeral 18 designates generally the other turn-around portion which is provided with a counting mechanism, as will also be described in detail hereinafter.

As will be apparent from FIGS. 2 and 3, there is provided on one side of the turn-around section 16 acasing 20. Within thecasing 20 are located a source of electrical energy, for example, abattery 21, and a miniatureelectrical motor 22. As seen in FIGS. 3 and 5, agear wheel 24 is located at the end of the shaft of themotor 22 and meshes with and drives agear wheel 26 fixedly secured to ashaft 28 about which a plurality ofwheels 30 are rigidly secured. Such miniature electric motor and gear construction is conventional in the art and need not be described further.

Thewheels 30 are provided with a plurality ofspokes 32, it being noted that both the wheels andthe spokes be apparent, actuation of themotor 22 by any conventional switch means causes theshaft 28 to rotate in turn causing all of thewheels 30 to rotate.

It will be further noted from FIG. 5 that theturnaround portion 16 is provided at the bottom thereof with a section of trackway 33 formed with a plurality of

racing areas

34, 34', 34" and 34" corresponding to the previously described

racing areas

14, 14', 14" and 14" illustrated in FIG. 2 and which are formed within the central section 12. As will be further apparent from FIG. 5, the turn-aroundsection 16 is provided at the top thereof with a section oftrackway 36 provided with a pluralityof

distinct racing paths

38, 38, 38", and 38" corresponding to the

racing paths

1,4 and 34 which have been previously described.

Turning now to FIG. 6, it willbe noted that mounted within the bottom section of trackway 33 of theturnaround section 16, as illustrated in FIG. 6, is a pivotably supported gate generally designated by the reference numeral 40 which consists of a plate 42 appropriately mounted for rotation and having at one end thereof a plurality of flanges 44 which are free to move upwardly and downwardly throughopenings 46 formed within each of the

paths

14, 14', 14", 14", as illustrated in FIG. 2. The other end of the plate 42 is providedwith anoperating handle 48 which when moved to one side causes the flanges 44 to protrude upwardly blocking each of the racing paths l4, 14', 14'' and 14". In like manner, as thehandle 48 is rotated to the left, the plate 42 rotates moving the flanges 44 below theopenings 46 thus leaving the paths of the trackway unobstructed.

As illustrated in FIGS. 4 and 7, the other turn-aroundportion 18 is provided with ashaft 50 upon which fourcylinders 52 are loosely mounted for independent rotation. Each of thecylinders 52 is provided with indicia 0123456789 along the periphery thereof, andupstanding teeth 54 corresponding to each of the indicia. As can be seen best in FIG. 7, as each of thedrums 52 rotates, one of theteeth 54 corresponding to one of the indicia protrudes upwardly into the path of travel of thevehicle 56.

The turn-aroundportion 18 is provided at the bottom thereof with a section oftrackway 58 formed with a plurality of

racing areas

60, 60, 60" and 60", as seen in FIG. 4, corresponding to the previously described

racing areas

14, 34 and 38. As will be further apparent from FIG. 7, the turn-aroundsection 18 is provided at the top thereof with a section oftrackway 62 provided with a plurality of distinct racing paths 64, 64', 64" and 64 corresponding to the

racing paths

14, 34 and 38 and 60 as previously described.

As will now be apparent, and with reference to FIG. 7, as thevehicles 56 have completed their 180 turns in the turn-aroundsection 18 and begin to move downwardly at the very end of theirrespective paths 60 eachvehicle 56 eventually engages and moves the projectingtooth 54 of itscorresponding cylinder 52 thus rotating thecylinder 52 and exposing the next indicia. A flexible spring 66 and a rigid spring 68 are positioned as illustrated in FIG. 7 adjacent a smaller series of teeth 70 formed in eachcylinder 52 and corresponding to thelarger teeth 54. Thus, thecylinders 52 are limited in their rotation to movement betweenadjacent teeth 54.

Located immediately below thecylinders 52 are a plurality of discs 72, each fixedly secured to ashaft 74 and provided with a pair ofteeth 76. Importantly, theteeth 76 of one disc 72 are staggered from the teeth of an adjacent disc 72, as partially illustrated in FIG. 4. Thus, as thevehicle 56 corresponding to theraised tooth 76 contacts same, thevehicle 56 is temporarily slowed down while causing theshaft 74 to rotate, in turn raising thetooth 76 of another disc 72 to slow movement of theadjacent vehicle 56, it being understood that the foregoing is all accomplished in random manner.

It is now apparent that each of thevehicles 56 must be configured the same on top and bottom, and it is contemplated that the small figurine of a driver be located on the top and bottom as illustrated in FIG. 2.

As will now be apparent, by rotating thehandle 48 to the right, each of thefourvehicles 56 may be aligned for starting. Themotor 22 is then turned on and thevehicles 56 released. Thevehicles 56 roll gently down the trackway section 33 until becoming lodged between theadjacent spokes 32 of therotating wheels 30. The vehicles are rapidly accelerated through 180 within the turn-aroundsection 16 thereafter moving down the section oftrackway 36 eventually falling into the corresponding path of the central trackway section 12. The vehicles then enter the turn-aroundsection 18 and under their own momentum enter and pass through the other turn-aroundsection 18. Thevehicles 56 then pass downwardly through the counter mechanisms and random deceleratingdevices 52 and 72, respectively, thereafter landing on their corresponding paths within the central segment 12 but in the opposite direction. In case of accidental lodging of vehicles in theturnaround section 16, it is only necessary to rotateknob 80, as illustrated in FIG. 4, which results in rotatingshafts 28 freeing the stuck vehicle from the turnaround section.
