Abstract
A toy vehicle trackset includes a base supporting a vertically extending tower. A toy vehicle trackway includes a vertically rising portion supported by the tower which transitions to a vertical loop and a plurality of helically arranged downwardly spiraling track loop portions. The track loop portion form intersections with the vertically rising portion of the track. Each intersection is covered by a shroud to prevent injury to a child user in the event of collisions within a given intersection. The trackway includes a return which is coupled to a toy vehicle accelerator whereby toy vehicles repeatedly cycle through the trackway set.
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.
U.S. Pat. No. 4,091,561 issued to Kimura sets forth a TRAVELING ROAD SYSTEM OF A TOY having a supporting base from which a tower extends upwardly and which supports a helical ascending roadway supported thereon.

BRIEF DESCRIPTION OF THE DRAWINGS
The features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The invention, together with further objects and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawings, in the several figures of which like reference numerals identify like elements and in which:
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.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
