Description




FIELD OF THE INVENTION




This invention relates generally to toy vehicle tracksets and particularly to those having trackset intersections.




BACKGROUND OF THE INVENTION




Toy vehicle tracksets are well known in the art and have enjoyed substantial popularity for many years. While such toy vehicle tracksets have varied broadly, most employ a trackway having a plurality of track segments each having a travel path together with a guiding means such as raised sidewalls or the like. The basic operation of toy vehicle tracksets is found in the travel of one or more toy vehicles around the trackway. The toy vehicles typically used in toy vehicle tracksets are either powered or unpowered. Powered vehicles typically employ a propulsion system utilizing a wind-up spring-driven power source or a battery-powered electric motor. Still others utilize a small electric motor deriving operative power from conductors buried in the trackway. Unpowered toy vehicles used in toy vehicle tracksets are typically freewheeling and rely upon various energy sources to drive the vehicle around the trackway. The power sources may, for example, be simple gravity-driven systems using one or more inclined ramps for acceleration or, alternatively, may employ one of several types of acceleration devices. Acceleration devices may include launchers having a launching station from which the toy vehicle is accelerated using spring or air power. One of most prevalent acceleration devices utilizes one or more spinning wheels positioned adjacent a closed loop toy vehicle trackway. In such acceleration devices, the wheel or wheels are rotated at a high rotational speed and as a toy vehicle passes the spinning wheel or wheels, the wheel or wheels engage the toy vehicle and impart energy thereto.




One of the general objectives in the fabrication of toy vehicle tracksets is the provision of increased amusement, entertainment and play value. Thus, practitioners in the art have provided various types of action or stunt features in toy vehicle tracksets. Such stunt or action features have included jumps and loops as well as trackset intersections. In providing trackset intersections, the additional excitement provided arises from the possibility or actual occurrence of toy vehicle collisions at the intersections.




U.S. Pat. No. 5,899,789 issued to Rehkemper, et al. sets forth a TOY CAR TRACK ASSEMBLY WITH PROPELLING MECHANISM AND COLLISION COURSE having a continuous track comprising a spiral track section interconnecting upper and lower track sections. The spiral track section exits onto a powered roller assembly which receives a toy car from the spiral track and impels it along the track. The car leaving the rollers moves over and opening in a horizontal section and then through an inverted vertically disposed loop leading back to the opening to a lower track section and back to the spiral track section. The construction of the track creates a midair collision course potential for cars moving simultaneously through the intersection.

FIG. 1

sets forth a perspective view of a toy vehicle trackset constructed in accordance with the present invention;





FIG. 2

sets forth a partially sectioned perspective view of the tower portion of the present invention toy vehicle trackset; and





FIG. 3

sets forth a partial perspective assembly view of an intersection of the present invention toy vehicle trackset.











DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

sets forth a perspective view of a toy vehicle trackset constructed in accordance with the present invention and generally referenced by numeral


10


. Trackset


10


includes a vertically extending tower


11


supported by a base


12


. Base


12


further includes a battery-powered accelerator station


20


having a pair of spinning rollers


21


and


22


. Trackset


10


further includes a vertically transitioning upper chute


40


supported by tower


11


. A toy vehicle trackway


13


preferably formed of a molded plastic material or the like extends upwardly from chute


40


along tower


11


to a vertical loop


41


. Loop


41


transitions to a plurality of horizontal and downward spiral loop portions


43


and


45


. Loop


41


forms an intersection


42


on tower


11


while loops


43


and


45


form intersections


44


and


46


respectively upon tower


11


. Loop


45


transitions to an exit loop


47


which in turn is coupled to a return curve


48


and a trackway return


49


. Toy trackway


13


is further supported by a pair of trackway supports


14


and


15


.




In further accordance with the present invention, intersections


42


,


44


and


46


are covered by hollow shrouds


52


,


51


and


50


respectively.




In operation, a toy vehicle such as toy vehicle


16


is shown entering accelerator


20


in the direction indicated by arrow


25


. In the preferred fabrication of the present invention, toy vehicle


16


is unpowered and freely rolling upon toy vehicle trackway


13


. For further illustration, an additional toy vehicle


17


is shown rising upwardly against tower


11


having been previously launched by accelerator


20


. Accelerator


20


is fabricated in accordance with conventional fabrication techniques and provides a pair of rapidly spinning rollers


21


and


22


. Rollers


21


and


22


spin in the directions indicated by arrows


23


and


24


. Accordingly, as toy vehicle


16


enters accelerator station


20


, rollers


22


and


23


engage toy vehicle


16


and rapidly accelerate it up chute


40


in the direction indicated by arrow


26


. In the anticipated play pattern of the present invention toy vehicle trackset, a plurality of toy vehicles are simultaneously operating upon toy vehicle trackway


13


. The user is able to exercise some timing by determining when each toy vehicle is moved into accelerator station


20


. Accelerator station


20


rapidly accelerates the toy vehicles with sufficient energy to cause the toy vehicles to travel upwardly as indicated by arrow


26


and leave tower


11


entering loop


41


as indicated by arrow


27


. Thereafter, centrifugal force maintains the toy vehicle against loop


41


as it descends in the direction indicated by arrow


28


entering intersection


42


. As is better seen in

FIG. 3

, intersection


42


provides a crossing of the trackway descending from loop


41


and the upwardly ascending portion of trackway supported by tower


11


. Thus, simultaneous presence of toy vehicles within intersection


42


results in a collision therein. Shroud


52


maintains the safety of intersection


42


by confining the trajectories of intersecting or colliding toy vehicles within intersection


42


.




In the absence of a collision within intersection


42


, the launched toy vehicle transitions through loop


43


downwardly in the direction indicated by arrow


29


and enters intersection


44


. Once again, intersection


44


is substantially identical to intersection


42


and is covered by shroud


51


. In the event a toy vehicle such as toy vehicle


17


is entering the upward track within intersection


44


at the same time as a descending vehicle leaves loop


43


and enters intersection


44


, a collision will likely result.




In the absence of a collision within intersection


44


, the descending toy vehicle traverses loop


45


in the direction indicated by arrow


30


entering intersection


46


. Once again, should simultaneous toy vehicles be traveling through intersection


46


, a collision will occur. In the absence of a collision within intersection


46


, the descending toy vehicle exits the loop structure at exit loop


47


in the direction indicated by arrow


31


. The descending toy vehicle having left exit loop


47


continues around return curve


48


and return


49


to again approach accelerator station


20


. At accelerator station


20


, the toy vehicle is again accelerated up chute


40


and the process continues.




In the anticipated play pattern of the present invention, a number of toy vehicles are rapidly and repeatedly placed upon trackway


13


and pushed into accelerator station


20


. Thereafter, the user is able to observe as the plurality of toy vehicles is rapidly launched upwardly through tower


11


and descends through loops


41


,


43


and


45


ultimately returning to accelerator station


20


.





FIG. 2

sets forth a partially sectioned perspective view of tower


11


and supported track segments of the present invention toy vehicle trackset. For purposes of illustration of the structure of tower


11


,

FIG. 2

omits accelerator station


20


as well as loops


41


,


43


,


45


and exit loop


47


.




More specifically, tower


11


is supported by a base


12


which defines an upwardly transitioning chute


40


. Tower


11


supports a vertically ascending portion of trackway


13


which, as is seen in

FIG. 1

, transitions to a vertical loop


41


. Trackway


13


further includes a plurality of intersections


42


,


44


and


46


which, as is described above in

FIG. 1

, are formed by the intersection of the vertically ascending portion of trackway


13


with loop portions


41


,


43


and


45


of trackway


13


.




In accordance with the present invention, intersections


42


,


44


and


46


are partially covered by a plurality of shrouds


52


,


51


and


50


respectively. The structure of shrouds


50


through


52


is substantially identical and is shown in greater detail in FIG.


3


. Shrouds


50


,


51


and


52


are substantially identical and are preferably formed of a relatively thin material such as molded plastic or the like. Each of shrouds


50


through


52


defines an opposed pair of vertically oriented apertures and an opposed pair of side apertures which facilitate toy vehicle travel in either a vertical or sideways descending direction beneath the shrouds.




Thus, shroud


50


is secured to tower


11


by a pair of fasteners


80


and


81


and defines a pair of vertical apertures


60


and


61


as well as a pair of side apertures


62


and


63


. Similarly, shroud


51


is secured to tower


11


by a pair of fasteners


82


and


83


and defines vertical apertures


64


and


65


together with side apertures


66


and


67


. Finally, shroud


52


which is shown in greater detail in

FIG. 3

is secured to tower


11


by a pair of fasteners


85


and defines vertical apertures


68


and


69


together with side apertures


70


and


71


.




As described above, shrouds


50


,


51


and


52


are substantially identical. Each shroud functions to partially enclose a respective one of intersections


46


,


44


and


42


to protect the user against potential injury as toy vehicles collide within the intersections. In the preferred fabrication of the present invention, the excitement of the play pattern may be enhanced by selecting the material which forms shrouds


50


,


51


and


52


. For example, in some instances an opaque material may be utilized and may be preferred. In other instances, however, shrouds


50


through


52


may be found more interesting and exciting if formed from a translucent or transparent material. In addition, the outer shape of shrouds


50


through


52


may be selected in accordance with a particular appearance theme.





FIG. 3

sets forth a partial perspective assembly view of tower


11


supporting shroud


52


. Once again, it will be remembered that the structure of intersection


42


and shroud


42


upon tower


11


is substantially identical to intersections


44


and


46


of shrouds


51


and


50


respectively. Accordingly, the descriptions in

FIG. 3

relating to shroud


52


and intersection


42


will be understood to apply equally well to the remaining shrouds and intersections of the present invention trackset.




More specifically, tower


11


supports a vertically ascending portion of trackway


13


together with a transverse section forming an intersection


42


. A track coupler


90


fabricated in accordance with conventional fabrication techniques receives a track segment


100


having a cooperating coupler


101


. Similarly, intersection


42


includes a track coupler


91


cooperating with a coupler


103


of track segment


102


. Thus, track segments


100


and


102


are fitted upon and secured to couplers


90


and


91


respectively to provide the transition portions of loop


41


and loop


43


to and from intersection


42


(loops


42


and


43


seen in FIG.


1


). Trackway


13


further includes a track coupler


92


which cooperates with a coupler


105


formed on track segment


104


. Thus, track segment


104


is securable to trackway


13


. As is seen in

FIG. 1

, the upwardly extending portion of trackway


13


forms loop


41


. Thus, with reference to

FIG. 3

, it will be seen that track segment


104


forms the initial portion by which trackway


13


transitions to loop


41


.




A shroud


52


fabricated of a thin plastic material or the like is secured to tower


11


by a pair of conventional fasteners


84


and


85


. Shroud


52


defines an aperture


68


on the bottom portion thereof and an aperture


69


on the upper portion thereof. In addition, shroud


52


defines a pair of side apertures


70


and


71


. Thus, in accordance with the present invention, shroud


52


covers intersection


42


while allowing toy vehicles to rise vertically beneath shroud


52


and descend sideways beneath shroud


52


passing through intersection


42


.




What has been shown is a novel toy vehicle trackset having a base supporting a vertical tower within which a vertically rising trackway portion is multiply intersected by descending helical loops. Each intersection is covered with a protective safety shroud to prevent injury to a child user as the trackset is being played with.
