In accordance with the invention, the amusement device comprises a toy vehicle and a trackway along which the vehicle moves. As embodied and shown in Figure 1,the reference numeral 20 designates the toy vehicle and the reference numeral 22 designates the trackway. Trackway 22 is provided with various track sections 24, 26, 28, 30, 32, and 34 in a continuous path along which the vehicle moves.

The toy vehicle 20, as best seen in Figures 1 and 2, is provided with a pair of front wheels 36 and a pair of rear wheels 38. Preferably the front wheels 36 are suitably mounted on the vehicular body to freely rotate while the rear wheels 38 are rotatably driven.

The toy vehicle also has rotatably driven gears and at least one rod extending from the vehicle. Preferably the rotatably driven gears comprise a pair of gears 40 extending from respective sides of the vehicle, and the rod comprises a rod 42 extending from the axle of the left rear wheel 38. To rotatably drive the rear wheels 38 and gears 40, a miniature motor of conventional configuration well known in the art is provided in the vehicle. This motor may be electrically powered by batteries or mechanically energized by springs and is operatively connected to the rear wheels 38 and gears 40.

The purpose of using rotatably driven rear wheels 38 and gears 40, and the vehicular rod 42, will be described in greater detail hereinafter. As will become apparent and as seen in Figure 1, however, the vehicle 20 is driven along the continuous trackway 22 and is imparted with different movements due to the inter-cooperation of the vehicle 20 and its components with the track sections of the trackway 22 and their components.

It was previously noted that the trackway 22 comprises six different track sections, 24, 26, 28, 30, 32, and 34 which are provided in a continuous path along which the vehicle 20 moves. For purposes of describing the preferred embodiment of the amusement device and its operation, the location of the toy vehicle shown in Figure 1 will be considered as the beginning portion of the trackway 22 for the movement of the vehicle 20.

When the motor of the vehicle is activated, the vehicle 20 is driven by its rear wheels on the trackway until it enters the track section 24. As best seen by reference to Figures 1 and 3, track section 24 has at its first end a pair of side ramps 44 and teeth means 46 positioned on the side ramps 44 which are engageable with the rotaably driven gears 40 of the vehicle 20 for elevating the front end of the vehicle 20 into an upwardly extended position. The width or distance between the two side ramps 44 is sufficient to allow clearance ofthe wheels 36 and 38 of the vehicle while the teeth means 46 engage with the vehicle gears 40.

As the driven gears 40 of the vehicle reach the upper portion ofthe teeth means 46 on the ramps 44, the vehicle is in its upwardly extended position and is then moved from the ramp 44 by the rotatably driven rear wheels 38. The center of gravity of the vehicle is such that the upwardly extended position of the vehicle is maintained after leaving ramps 44 at the same time the vehicle is being driven along the middle portion of the track section 24 by the rear wheels 38. As shown in Figure 1, the track of first section 24 can be provided along its center with a rail 48 which is engageable with corresponding guide means on the rearward bottom portion of the vehicle 20. This serves to guide the vehicle 20 along the first track section 24. By doing so, it is apparent that the configuration of the first track section can be varied to impart different directions to the vehicle.In the preferred embodiment track section 24 is substantially horizontal and consists of both curved and straight portions.

As best illustrated in Figures 1 and 4, the first track section 24 has at its final end step means 50 located on the track for returning the upwardly extended vehicle 20 to a normal horizontal position. This is achieved when the rear wheel 38, which are driving the upwardly extended vehicle 20 along the track, move across the step means 50. The action causes a frontward momentum so that the vehicle is again positioned in a normal manner on the trackway as illustrated in the lefthand side of Figure 4.

As illustrated in Figures 1 and 4, as the vehicle 20 leaves track section 24, it enters the connected track section 26. Movement of the vehicle along the track section 26 is provided by the rotatably driven rear wheels 38. As best shown in Figure 1, the second track section 26 comprises a series of steps alo Ig upwardly and downwardly inclined track portions to impart a bumpy movement to the vehicle 20 as it moves therealong. In the preferred embodiment, track section 26 has a circular-like configuration. To ensure proper movement of the vehicle along this path, side guide rails 54 are provided.

As the vehicle 20 leaves track section 26, it enters the connected track section 28 which is provided with a double-inclined tower 56. As illustrated in Figure 1, the double-inclined tower 56 has a first upwardly inclined tower section and a second downwardly inclined tower section. Upstanding portions 58 provided on the sides of the upwardly inclined tower section each have a continuous rack of teeth 60 and a rail 62 spaced therefrom. When the vehicle 20 enters the double-inclined tower 56 from the track section 24, it will be apparent from the configuration of the racks of teeth 60 and rails 62 of the upstanding side portions 58 that the gears 40 engage the racks of teeth 60.Rotation of the gears 40 along the racks 60 causes the vehicle 20 to move upwardly along the racks 60, it being understood that the rails 62 function principally to confine the rotating gears 40 into engagement with the racks 60.

In addition to the above, the first upwardly inclined tower section of tower 56 has cam means provided on at least one of the upstanding side portions 58 engageable with the rod 42 of the vehicle 20 for imparting a rocking movement to the vehicle as the vehicle moves upwardly. As herein embodied and as shown in Figures 1 and 5, the cam means comprises a lower cam guide rail 64 which is non-continuous and interrupted by spaces and extends from the leftward upstanding side portion 58. As the vehicle 20 is driven upwardly by the gears 40 in engagement with the racks of teeth 60, and vehicular rod 42 moves along the cam guide rail 64. This results in a steady upward movement of the vehicle until the vehicular rod 42 disengages with the guide rail 64.

When the rod 42 enters one of the series of spaces, a downward rocking movement is imparted to the vehicle 20 until the rod reengages with the next sequential guide rail 64. This is best illustrated in the side view of Figure 5 showing the vehicular rod 42 in cooperation with the guide rail 64 as the vehicle moves upwardly along the tower 56. This inter cooperation is further shown in the rear view of Figure 6 taken along the line 6-6 of Figure 5.

As illustrated in Figures 8 and 9, the second downwardly inclined tower section also has upstanding side portions 58 each having a continuous rack of teeth 60 and a rail 62 spaced therefrom. When the vehicle 20 is in the downwardly inclined section of the tower 56, it will be apparent from the configuration of the racks of teeth 60 and rails 62 that the gears 40 of the vehicle engage the racks of teech 60. Rotation of the gears 40 along the racks 60 causes the vehicle 20 to move downwardly along the racks 60, it being again understood that the rails 62 function principal-16 to confine the rotating gears 40 into engagement with the racks 60.

As herein embodied, at least one side portion 58 of the downwardly inclined tower section is provided at a first end with cam means engageable with the vehicular rod 42 for imparting a steady downward movement to the vehicle. Preferably, and as best shown in Figures 8 and 9, this cam means comprises an upper cam rail 66 along which the vehicle rod 42 moves. When the vehicle 20 reaches the upper end of the upwardly inclined section of the tower 56, the vehicular rod 42 leaves the last lower cam rail 64 and by virtue of the center ofgravity and the momentum of the vehicle into a downward position, the vehicular rod 42 moves into cooperation with the upper cam rail 66. The vehicle 20 will then continue to move in a steady downward movement as long as the vehicle rod 42 is in engagement with the upper cam rail 66.

As was previously mentioned, only the first end of the downwardly inclined section of the tower 56 is provided with the upper cam rail 66. Accordingly, with the body of the vehicle 20 being freely rotatable about the driven vehicular gears 40 that are engaged with the racks 60 and when the vehicular rod 42 disengages the end of the upper cam rail 66, the vehicle somersaults front end first due to gravity an vehicular mass momentum. As the vehicle 20 steadily moves downwardly to the tower bottom from engagement of the gears 40 and with racks 60, the vehicle will continue to somersault front end first.

This is best illustrated in Figure 8. In the preferred embodiment, the vehicle 20 is imparted with three somersaults and reaches the bottom of the tower with the front end of the vehicle 20 facing the track at the tower bottom. As will be seen from Figure 8, the lower portion of the tower is formed in a curved configuration to facilitate the movement of the vehicle 20 from a downward position to a substantially horizontal position of the vehicle on the track.

The number of somersaults and position of the vehicle in the above operation is, of course, dependent upon such design factors as degree of inclination and length of the tower section, the location on the tower section at which the upper cam rail 66 ends, and the weight and center of gravity of the vehicle 20.

After the vehicle 20 reaches the bottom of the tower 56 and leaves the track section 28, it enters a track section 30 of an S-shaped configuration. As herein embodied, track section 30 includes a series of substantially vertically-extending poles positioned along the side of the track section to be engaged by the rotatably driven gears 40 extending from the vehicle 20 to impart an S-shaped movement of the vehicle along the track section.

Preferably, the substantially vertically-extending poles comprise a series of three poles 68,70, and 72, positioned along the S-shaped track section 30 in the manner illustrated in Figures 1 and 10. With this configuration, when the vehicle 20 leaves the tower 56, the gear 40 on the right side of the vehicle 20 hits the first pole 68 on the right side of the S-shaped track section 30. Because the rear wheels 38 are driving the vehicle 20 on the track at this time while the right gear 40 abuts against the first pole 68, the vehicle is moved rightwardly until the gear 40 on the left side of the vehicle hits the next pole 70 positioned on the left side of the track. In a similar fashion, because the rear wheels 38 are still driving the vehicle 20 on the track while the left gear 40 abuts the pole 70, the vehicle is moved leftwardly.

This action continues until the rightward gear 40 of the vehicle 20 abuts the third pole 72 sequentially positioned above the right side of the track. A rightward movement again is imparted to the vehicle 20 until the rightward gear 40 disengages from the pole 72. To ensure that the vehicle 20 is imparted with an S-shaped movement along the S-shaped track section 30, side guide rails 74 as shown in Figures 1 and 10 are provided along the track and the track is formed with appropriate inclinations along the different curves of the S-shaped configuration.

As the vehicle 20 leaves the end of the track section 30, it enters track section 32. The features of track section 32 are best illustrated by reference to Figures 1, 10 and 11. As herein embodied, track section 32 has at its first end a side ramp 76 engageable with the wheels on one side of the vehicle 20 for elevating that one vehicular side into an upwardlytilted position. Preferably side ramp 76 is positioned on the left side of the track section 32 wherein the wheels 36 and 38 on the left side of the vehicle 20 move up the side ramp 76 until that side is in an upwardly tilted position.To ensurethatthe vehicle is smoothly moved into this tilted position, a secondary side ramp 78 having a downward inclination is located on the right side of the track section 32 wherein the gear 40 on the right side of the vehicle is moved downwardly onto the track of section 32. The vehicle is balanced in its upwardly tilted position by the driven gear 40 and wheels 36 and 38 on the downwardly positioned or right side of the vehicle 20 resting on the track.

By virtue of the rear wheel 38 and gear 40 on the right side of the vehicle 20 being driven along the track, the vehicle moves along the track in an upwardly tilted position until it reaches the other end of the track section 32. Preferably, the track section 32 is formed in a curved horizontal configuration and provided with an outer leftward side guide rail 80.

The wheels on the right side of vehicle 20 abut against rail 80 while travelling along the track so that the vehicle in its tilted position is imparted with a movement around the curved track until it reaches the other end.

As best seen in Figure 11,there is provided at the other end of the track section 32 an upwardly inclined side ramp 82 for engagement with the gear 40 on the right side of the vehicle 20. As the vehicle 20 reaches ramp 82, the gear 40 moves upwardly along ramp 82, and in doing so, causes the vehicle to be returned from its tilted side position to a normal horizontal position on the track section 32. To ensure that the gear 40 is aligned for engagement with side ramp 82 and the vehicle 20 is aligned for entry into the next track section 34, a center guide rail 84 and side guide rails 86 are provided at that end of the track section 32 to position the vehicular wheels and thus the vehicle into a proper location.

It will be apparent from Figure 1 and 11 that the next track section 34 has a tower 88. The tower 88 comprises side portions 90 provided with continuous racks of teeth 92 substantially vertically positioned for engagement by the rotatably driven gears 40 of the vehicle 20 to impart an upward movement to the vehicle to an elevated level of the tower. A rail 94 is spaced from each of the continuous racks of teeth 92 on each of the side portions 90, it being understood that the rails 94 function principally to confine the rotatably driven gears 40 of the vehicle into engagement with the racks of teeth 92. Rotation of the driven gears 40 along the racks 92 causes the vehicle 20 to move upwardly along the racks 92.At the elevated level of the tower 88, hereinafter designated by reference numeral 98, the racks of teeth 92 and rails 94 are curved to move the vehicle into a substantially horizontal position on that elevated level 98.

As herein embodied, at least one of the side portions 90 of the tower 88 is provided with cam means engageable with the vehicular rod 42 for imparting a steady and substantially vertically upward movement to the vehicle. As best shown in Figures 12 and 13, the cam means comprises a lower continuous cam rail extending from the left one of the side portions 90 of the tower 88 wherein the vehicular rod 42 rides along the lower cam rail 96 to ensure the substantially vertical movement of the vehicle upwardly.

With reference to Figure 11, as the vehicle leaves the end of track section 32, the gears 40 of the vehicle are placed into position for engagement with the continuous racks of teeth 92 by side ramp 82, center guide rail 84, and side guide rails 86. The vehicle 20 is then moved vertically upwardly by the interaction of gears 40 and racks 92 and rod 42 with cam rail 96 until it reaches the elevated tower level 98.

As best seen in Figures 1 and 12, the tower 88, at the elevated level 98, further includes a ramp 100 extending from the tower. The ramp is rotatably attached to the tower and normally biased in a substantially horizontal position for movement of the vehicle 20 from the elevated level 98 of the tower onto the ramp. The biasing of the ramp can be achieved with any suitable means, such as by using a spring 102 as shown in Figure 12. At the outer end of the ramp 100, there is further provided an upright outer plate 104 for engagement with the front end of the vehicle 20 as it moves onto the ramp.

When the vehicle is driven by the rear wheels 38 from the elevated level 98 of the tower 88 onto the ramp 100, the weight of the vehicle causes the ramp to be moved downwardly, overcoming the bias of the spring 102. As the ramp begins to move downwardly, the front end of the vehicle 20 engages with the upright outer plate 104. This combined action causes the vehicle to somersault rear end first onto the track at the bottom of the tower 88 into a normal horizontal position. this movement is best illustrated by reference to Figure 12. To facilitate the return of the somersaulting vehicle to the normal horizontal position on the track at the bottom of the tower, track section 34 further includes resilient pad means 106 at the bottom of the tower 88 for receiving the vehicle and uprighting it onto the track.

It will beapparentfrom Figure 1 that the vehicle 20, after leaving the tower 88 and the track section 34, returns to the beginning portion of the continuous trackway 22 for further movement around the trackway 22 in the manner previously described.

In view of the foregoing written description of the preferred embodiment and accompanying drawings, it is seen that the vehicle 20 is imparted with various unique and different movements as it travels along the continuous trackway to various track sections 24, 26, 28, 30, 32, and 34. It is further seen that the toy vehicle and trackway can be formed in different separable parts for easy storage and assembly and is simple in construction and can be formed of a hard plastic for durability and safety of the children playing with the device. It will be apparent, however, to those skilled in the art that modifications and variations could be made in the vehicle and trackway in accordance with the teachings of the invention without departing from the spirit or scope of the invention. Thus it is intended that the present invention cover the modifications and variations of this invention within the scope of the appended claims and their equivalents.
