Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to small car action toys.
2. Description of the Prior Art
Track systems for small toy cars are usually designed to be
assembled on a living room floor for use with powered toy vehicles.
If unpowered toy vehicles are to be used, small inclined frames may
be included to form a small hill down which the vehicles can roll
to gain speed. However, cost and packaging restrictions limit such
frames to small hills, which results in low vehicle speed and
inability to traverse long track layouts or properly move over
accessories that require high vehicle speeds. Prior art track
systems also do not readily lend themselves to arrangements for
using two tracks together to provide racing games and stunt action
sets where vehicles from the two tracks interact.
SUMMARY OF THE INVENTION
One object of the present invention is to provide an economical
track layout which enables unpowered toy vehicles to gain high
speed.
Another object is to provide novel and entertaining accessory means
for a toy track system.
In accordance with the present invention, a small car action toy is
provided which includes track means forming a path for a toy
vehicle. The track means is adapted to be connected to an elevated
support, so one end can be raised to a substantial height. The
track means is flexible to enable it to droop from the elevated
support to the floor below so that at least some of the following
track portions are supported by the floor.
Accessory means are provided which may be connected to the track
means for changing the action of vehicles along the path of travel.
The accessory means include a starting gate, a finish gate, a loop,
a ski jump, a banked curve, and a merger (for merging two tracks
into a single track). The track means includes individual track
sections of short length for facilitating packaging, and connector
means for connecting the track sections together.
The novel features of the invention are set forth with
particularity in the appended claims. The invention will be best
understood from the following description when read in conjunction
with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates a small car action toy constructed in accordance
with the invention, which is generally designated at 10. The toy
includes track means 12 forming a path for toy vehicles, such as
vehicles 14 and 16. The track 12 includes a first end 18 adapted to
be attached to an elevated support 20, such as a table top, by
connector means 22. The track has sufficient flexibility that it
droops from support 20 to the floor, so that at least one portion
of the track means is supported by the floor. Thus, toy vehicles
initially move down a long steep incline so that they have
sufficient speed to properly traverse the track course.
The action toy includes accessory means which may be connected in
series with the track to interact with the vehicles in a novel
manner. FIG. 1 illustrates seven of such accessory means including
a starting gate 36, a loop 24, a 90.degree. curve 26, a ski jump
28, a 180.degree. curve 30, a finish gate 32, and a track merger
34. Duplicate accessory means including a second track 12A, second
loop 24A, second 90.degree. curve 26A, second ski jump 28A, and
second 180.degree. curve 30A can also be provided for a second of
the cars. By starting the cars 14 and 16 together at the starting
gate 36, they can be made to race over similar courses to the
finish gate 32, and then through the merger 34 to a common track
284.
FIGS. 2 through 5 shows details of the starting gate accessory
means 36, which may be used to simultaneously start the cars 14, 16
(shown by arrows in FIG. 2) for a race. The starting gate includes
a frame or housing 38 having a bottom wall 40, a top wall 42, a
rear wall 44, a front wall 46 and a pair of side walls 48, 50. The
top wall 40 serves as a starting surface to hold the cars 14, 16 in
a laterally spaced relationship so they can move over different
tracks. The side walls 48, 50 have comparatively narrow front
portions 52 and wide rear portions 54, causing the top wall 42 to
slope downwardly from its rear end 58 to its front end 56 so that
the cars 14, 16 will be accelerated by gravity when they are
permitted to roll down top wall 42.
Cars 14, 16 are retained in position on top wall 42 by stop members
60, 62, respectively, that abut the front bumpers of the cars. The
stop members 60, 62 are carried by laterally-extending flanges 64,
66, respectively. The flanges 64, 66 are supported on an actuator
65 that is pivotally connected to top wall 42 by a living hinge at
67. A living hinge is a reduced-section in an integral member of
flexible material such as polypropylene.
Actuator 65, which is designed for manual operation, i.e. by a
child pressing down on it, is biased to the position shown in FIGS.
1 through 4 by a rod-like cantilever spring 70. This spring 70 has
its free end 72 engaged in an inverted, V-shaped slot 74 provided
in a depending plate 76 carried by actuator 65. The fixed end 78 of
the spring is affixed to a shelf 80 provided on bottom wall 40, by
a retaining clip 82. When the actuator 65 is depressed by a child,
the stop members move down simultaneously through apertures 81, 83
in the top wall, thereby simultaneously releasing the vehicles.
The starting gate accessory means 36 also includes a pair of
integral connectors 84, 86 which extend forwardly and downwardly
from front wall 46, at the downpath end of the frame, for receiving
the end 18 of track means 12 and the end 18A of a parallel track
means 12A, respectively, which droop towards the floor. Connectors
84, 86 are adapted to engage channels 87 and 88 provided in tracks
12, 12A, respectively. Connectors 84, 86 are retained in position
within their associated channels 87, 88 by protruberances 90, 92.
The protuberances 90 and 92 extend from opposite faces of the
connectors to enable tight engagement with the connecting track
sections.
The starting gate 36 may be connected to the table 20 or other
elevated support by the connector means 22. The connector means is
in the form of a C clamp with an anvil 94 and a screw 96. The anvil
is placed over an edge of the table, and the screw 96 is then
tightened to hold it in place. The connector means or clamp 22 has
a bracket or land 98 which is designed to hold a section of track
12 by engaging the walls of the channel 87 therein. However, it
also can engage a channel 100 provided in bottom wall 40 of the
starting gate 36. In addition to the land 98, the clamp is provided
with a pair of lands 102, 104 on the long leg 106 of the anvil. The
pair of lands 102 and 104 are employed when the clamp engages a
vertically extending board of table top means, instead of a
horizontal table top, since engagement with a vertical board
results in only the lands 102 and 104 being almost horizontal. The
two lands 102 and 104 enable two parallel tracks to be connected to
the clamp when this is desired. In order to attach the clamp to a
table, the screw 96, which threadably engages a first short leg 108
on the clamp anvil, is turned to advance it toward a second short
leg 110, to hold the table 20 between the screw and the second
short leg. The second short leg 110 has cutaway portions 111 and
113 that can receive edge molding and the like which may be present
at the table top means. The portion 111 is designed to receive
strips of decorative trim, while the portion 113 is designed to
receive piping that is generally present at the edges of sofa
cushions, matresses, and other upholstered pieces which serve as
elevated table top means to be clamped onto.
FIGS. 6-10 illustrate the loop accessory means or loops 24, 24A.
Each includes a usually straight track section 116 which is held in
the shape of a loop by a loop-forming frame or jig 118. The jig of
each loop such as loop 24 may be conveniently molded from a
suitable plastic material in two identical halves 120 and 121. Each
half 120, 121 includes a base 122 carrying an integrally-formed
arcuate track section 124. The arcuate track section 124 has a
first end merging into a connector 128 for connection to the main
track 12 (or track 12A, as the case may be). The arcuate track
section also has a second elevated end 130 merging into a long
curved connector 132 for joining to an end of track section 116, by
engaging channels 87 of track section 116. Stand portions 131,133
support the jig halves on the floor. The identical halves 120 and
121 may be connected together by brackets 134, 135 formed on the
jig halves during the molding operation. Each bracket 134, 135
includes a keyhole slot 136 at one end and a protuberance 138 at
the other end. With this arrangement, identical jig halves may be
connected by reversing them and engaging protuberances 138 on one
jig half into the keyhole slot 136 on the other jig half.
The end 126 of the jig half receives vehicles moving substantially
parallel to the ground, while the arcuate track sections 124 of the
jig halves establish a one-turn helix for the vehicles. Finally,
the vehicles are discharged at the end 126 of the other jig half
121 in a direction substantially parallel to the ground, and moving
in the same direction as they were received. The vehicles must have
an appreciable speed in order to pass around the loop. The speed
attained by passing down a long incline from a table top generally
is sufficient to enable passage around a small loop, in spite of
friction-caused decreases in speed prior to reaching the loop.
FIGS. 11-16 show details of the 90.degree. curve accessory 26,
which is shown supported above the ground by a bridge support or
trestle 140. As shown in FIG. 11, the curve comprises a frame 142
which supports a curved and banked track portion 144 for connection
in series with the main track 12. A connector 146, 148 is formed at
each end of the track portion, for engagement with the channel on
the underside of an adjoining track section. The frame can be laid
on the floor, or can be supported by the trestle 140 by engagement
of the trestle with a bracket 150 on the frame. As shown in FIG.
13, the frame includes a support wall 151 which can support the
outer edge of the curved track when the frame rests on the
floor.
The banking of the curve varies from a preliminary level such as
20.degree. at each end 152 and 154, as shown in FIG. 12, to a high
level such as 55.degree. at the center 156, as shown in FIG. 13.
The substantial preliminary banking away from a horizontal plane at
each end, twists the adjoining track sections into a gradually
increasing banking angle. As a result, the rotation of the vehicles
about their longitudinal axes while entering and leaving the banked
track area occurs more gradually. A more rapid angular acceleration
of the vehicles about their longitudinal axes would tend to make
them unstable. While the same low angular acceleration could be
achieved by using a larger curve, this would add to the cost of the
accessory. It if often desirable to support the curve accessory
above the ground, as on the trestle 140, to hold adjacent portions
of track 12 above the ground where they can easily be twisted into
the initial banking angle.
FIGS. 15 and 16 illustrate the manner of connection of the curve
accessory 26 with a track 12. If it is assumed that the vehicles
will move in the direction of arrows 158, then the vehicles will
leave the curve at the end having the connector 148. It is
desirable to bend over slightly the side walls 13 of the track to
prevent a vehicle wheel from hitting a protruding side wall.
Similarly, the sides of the curved track portion 144 can be bent
outwardly slightly at the end 152 where the vehicles enter the
curve.
FIG. 17 shows details of the trestle 140, which is designed to
support a simple track section, as well as some of the accessories
such as the curve 26 described above. The trestle includes a
bridge-like frame 160 which has a flat-topped bracket or land 162
on an upper beam 164. The land has eight sides for facilitating
engagement with a track member, such as an accessory or a simple
track 12 which has walls forming continuous channels 87. The large
sides 166 of the land are a distance G apart, while the small sides
168 are spaced a larger distance H apart.
In order to attach the trestle 140 to a track 12, the track is
placed on the trestle with the track channels 87 formed by channel
member 89 that extend toward each other, oriented parallel to the
long sides 166. Then the trestle is turned 45.degree. so that the
short sides 168 enter the channels 87. In comparing the trestle
land with the track 12, it may be noted that the spacing G of the
long sides of the trestle land is slightly less than the spacing G'
of the closest portions of the channel members 89. Also, the
spacing H of the short trestle sides is only slightly less than the
width H' between the bottom of the track channels 87 into which the
short sides fit. This construction allows firm engagement of the
trestle with the track member by a simple twist. The trestle does
not have to be started at one end of a track section and slid all
the way down to its final place.
The trestle 140 is designed for attachment to another trestle on
top of it, for a two or greater level interchange. The legs 170 and
172 of the trestle frame 160 have undercut keyways 174 in them,
while keys 176 are formed on each side of the trestle beam 164.
FIG. 18 illustrates the manner in which a key 176 of one trestle
fits into the keyway of another trestle. The engagement is made by
sliding the ends of the keys into the keyways.
FIGS. 19 through 21 illustrate the ski jump accessory 28 which
allows a fast-moving vehicle to fly through the air for a small
distance. The jump comprises two identical ramp members or jump
sections 180 and 182, placed so that there is a gap between them.
One jump section 180 is used to direct a vehicle over the gap while
the other 182 receives the flying vehicle. The jump section 180
includes a frame 184 which has an inclined track portion 186. High
walls 188 extend along each side of the track portion. The walls
188 are curved or flared outward at the upper part 190 of the
incline, but at the bottom of the incline they are spaced
approximately the same as the side walls of the rest of the track
system. The lower part 192 has a connector 194 for reception in the
channel 87 of an adjoining track 12, to hold it to the adjoining
track.
The frame 184 includes a stand 196 for supporting the upper end 190
of the track portion above the ground. The stand 196 is constructed
as a separate unit to facilitate packaging. It is joined to the
track portion by keys 198 in the track portion that fit into
keyways 200 in the stand. The jump is set up by placing two jump
sections at a particular spacing so that the vehicles can fly
across when they are traveling at the anticipated speed. The
sections should be aligned with each other, although the outward
flaring of the sides 188 allows the vehicles to be captured even
with considerably misalignment. The side walls 188 are preferably
considerably higher than the maximum diameter H of the vehicle
wheels of vehicles generally moved over the jump, and are generally
higher than the bodies of the vehicles. This is to facilitate
capturing a speedy vehicle that has jumped high.
FIGS. 22 through 25 illustrate a 180.degree. curve accessory means
30. This member is constructed in a manner similar to the
90.degree. curve described above, in that is has end portions 202
and 204 which are banked at an appreciable angle such as
20.degree.. The center 206 of the track portion 208 is banked even
more, such as an angle of 55.degree.. As mentioned above in the
case of the 90.degree. curve accessory, the initial banking causes
the track sections connected to each end of the curve to be twisted
into a gradually increasing banking. This reduces angular
acceleration of the vehicle about a longitudinal axis to promote
its stability. The 180.degree. curve accessory includes connectors
210 and 212 at each end for connecting to adjoining track sections.
A frame 214 supports its track portion either on the ground or on
trestles. A pair of brackets 216 and 218 similar to the bracket on
the 90.degree. curve, enable attachment to trestles.
FIGS. 26 through 29 illustrate the finish gate accessory means 32
for use when racing two vehicles, to indicate which vehicle has
won. The finish gate includes a frame 220 with a pair of laterally
spaced connector lands or brackets 222 and 224 on its bottom member
226. The brackets are designed to be received into the channels 87
and 88 on the under side of the tracks 12 and 12A and to be moved
along the length of the track sections to a desired location. Thus,
vehicles traveling on the tracks 12, 12A pass through the finish
gate and continue moving along the tracks.
A flagging member 232 which is pivotally mounted at a shaft 234 on
the frame, can fall to either side to indicate which of the two
cars has won. The flagging member is operated by a pair of levers
236 and 238 which are pivotally mounted on the top member 240 of
the frame.
The levers 236,238 have lower ends 242,244 which are designed to be
struck by the vehicles so that they pivot the lever backwards and
upwards. Prior to the levers being struck by a vehicle, holding
elements 246 and 248 on the levers engage the flagging member to
maintain it in an upright position. However, the first lever to be
struck releases the flagging member to allow it to fall towards its
side of the frame. The lever then falls until it is stopped by one
of the stop ledges 250 or 252 on the frame sides 254,256.
The shaft 234, which pivotally supports the flagging member, is
engaged with a bearing member 258 at the bottom of a bracket 260
that depends from the top member 240 of the frame. A knob 262 at
the end of the shaft 234 retains it in place. The shaft 234 is
located below the center of gravity of the flagging member, so that
once the flagging member begins to fall to one side, it continues
to fall until it hits a stop ledge. However, unless the flagging
member is made to start falling to one side, it is uncertain as to
which direction it will fall. The levers 236 and 238 are
constructed to make sure that the flagging member will fall toward
the lever that is first moved back by a vehicle, as will be
described below.
As shown in FIG. 28, the levers, such as lever 238, are pivotally
joined to a support 262 on the top member 240 by a living hinge
264. The living hinge comprises an area of reduced cross section in
a flexible material such as polypropylene. The flexible material
out of which the lever is constructed allows it to twist slightly
which is important in the operation of the device. As shown in FIG.
29, the holding elements 246 and 248 have edges 266 and 268 that
engage opposite sides of the flagging member 232. The width W of
the flagging member is greater than the separation of the forward
portions of edges 266 and 268 when the levers 236 and 238 are
unstressed. Thus, in order to fit between the forward part of the
edges 266, 268, the levers 236, 238 must be bent or twisted apart
slightly.
Outward movement of the edges 266, 268 that hold the flagging
member is accomplished by slight twisting of the levers. When one
of the levers, such as lever 236, is pushed back by a first
vehicle, the backward movement of its holding element 246 allows
the flagging member to fall to the left side, in the direction of
arrow 270. The holding element 248 of the other lever 238 helps by
thrusting the flagging member in the direction of arrow 270, while
the lever 238 untwists. This provides a positive movement of the
flagging member to one side. If a second car hits the lever 238 a
moment later, it will have no effect because the flagging member
has already started to fall to the left. In order to increase the
thrust on the flagging member, the edges 266 and 268 are angled so
the levers twist even more as one lever is pushed back. The angling
also allows the levers to be only slightly stressed until the last
moment when a car hits a lever, so that the introduction of
permanent set is minimized.
The flagging member 232 is provided with a checkered design
simulating the checkered flags generally used at the finish of auto
races. A handle 272 is provided to aid in grasping the flagging
member during resetting. Resetting for a new race is accomplished
by moving the flagging member upright and slightly spreading apart
the levers so that the holding elements 246, 248 lie on opposite
sides of the flagging member.
FIGS. 30 and 31 illustrate merger accessory means 34 for allowsing
vehicles received from two track sections 280 and 282 to travel
along a single track section 284. The merger apparatus comprises a
track portion 286 having a wide up-path end 288, which is at least
as wide as two track sections, with connectors 290 and 292 for
connection with the track sections 280 and 282. Side walls 294 and
296 continually narrow the track portion from a position near the
up-path end until it is only as wide, at the downpath end 298, as
the path of a single track section. The side walls 294 and 296 are
almost parallel at the up-path end, but they quickly curve so they
are angled toward each other at a continually increasing angle. At
a position 298 they gradually turn the other way, so they are at a
continually decreasing angle until they become parallel. The
narrowest part of the track portion, where it is within 10 percent
of the narrowest width, extends a substantial distance D which is
more than one-third the length of the track portion 286 of the
merger accessory. This substantial distance D of the narrowed
portion is desirable to stablize the vehicle so it is running
straight along the track. Along almost all of the track portion,
the height H of the walls is greater than the height V of the
wheels, shown at 300 and 302, of a vehicle 304 which is designed to
run along the merger accessory. Another connector 306 is located at
the downpath end of the merger to connect to the track section
284.
Thus, the invention provides means with several accessories for
novel operation and guiding of the vehicles and track sections
therefor. Although particular embodiments of the invention have
been described and illustrated herein, it is recognized that
modification and variations may readily occur to those skilled in
the art, and consequently, it is intended that the claims be
interpreted to cover such modifications and equivalents.
