This application claims priority of Provisional Application 60/598,852 entitled BELLOWS ACTUATED STUNT DEVICE FOR TOY VEHICLE TRACKSET filed Jan. 23, 2004 on behalf of the applicants of the present invention.
This invention relates generally to toy vehicle tracksets and particularly to actuated stunt mechanisms utilized therein.
Practitioners in the art have for many years attempted to improve the amusement value of toy vehicle tracksets by adding a variety of so-called stunt devices. Stunt devices have included such apparatus as loops, jumps, collision intersections and the like. The objective is to provide activity which improves the basic operation and amusement value of the toy vehicle trackset. One of the more recent trends in such toy vehicle tracksets is the inclusion of stunt devices which are actuated or operated under the control of the user. This participation further enhances the entertainment value of the trackset. For example, U.S. Pat. No. 6,322,417 issued to Bass sets forth an AIR-DRIVEN HOPPING TOY having a toy frame supported by a pair of pivotable legs and an extendable air cylinder. The extendible air cylinder is coupled to a compressible air bellows. Actuation of the air bellows forces extension of the air cylinder driving the toy and its supporting frame forwardly in an upwardly directed leap. A toy figure is supported upon the frame and appears to be the “pilot” of the hopping toy.
U.S. Pat. No. 3,858,875 issued to Nemeth et al. sets forth a GAP JUMPING TOY VEHICLE GAME which includes a vehicle track and a toy vehicle adapted to move along the track. A vertical jump defined by a pair of ramps is positioned within the track. The ramps are independent of one another and are aligned in space relationship to each other to define a gap therebetween. At least one of the ramps is movable with respect to the track and the other ramp to permit adjustment of the gap distance to be jumped.
U.S. Pat. No. 4,383,688 issued to Prehaodka sets forth an OBSTACLE FOR TOY VEHICLE including a pivotable vane positioned between two lanes of a multiple lane trackset. The vain is actuated by a toy vehicle to obstruct one of the lanes after the toy vehicle has passed. As a result, pursuing vehicles may encounter an obstructed lane and must be diverted to other lanes to avoid colliding with the obstacle.
U.S. Pat. No. 4,513,966 issued to Mucaro et al. sets forth a VEHICLE JUMP FOR A TOY VEHICLE GAME having a track intersection within which a plurality of upwardly directed ramps are positioned. Toy vehicles traversing the intersection may collide or avoid colliding with other toy vehicles depending upon the timing between toy vehicles.
U.S. Pat. No. 4,519,789 issued to Halford et al. sets forth a COMBINED JUMP MEANS AND TOY VEHICLE WITH SIMULATED STUNT HOOP in which a toy vehicle track defines a launch ramp and a receiving ramp spaced by a predetermined distance. Between the launch ramp and receiving ramp, a simulated flaming stunt hoop is suspended. The objective is to drive the toy vehicle so as to jump from the launch ramp to the receiving ramp while passing untouched through the simulated flaming stunt loop.
U.S. Pat. No. 5,038,685 issued to Yoneda et al. sets forth a TRACK APPARATUS FOR A TOY RACING CAR having a car entry track portion, a car exit car portion and a pivotal arm mounted between the two track portions. The pivotal arm is operative to carry a car from one portion to the other.
U.S. Pat. No. 4,715,843 issued to Ostendorffet al. and U.S. Pat. No. 3,621,602 issued to Barcus et al. set forth further examples of jumping stunt toy vehicle trackset apparatus.
In addition to stunt sets, several types of toy vehicle launchers have been provided by practitioners in the art. For example, U.S. Pat. No. 5,254,030 issued to Ostendorff et al. sets forth a RAPID ACTION TOY VEHICLE LAUNCHER having a base supporting a launch station which is coupled to a track portion. A pair of feed ramps are positioned on each side of the launch station and secured to the base. The launch mechanism within the launch station alternates in receiving a toy vehicle from each of the feed ramps and thereafter launching it onto the trackway. The mechanism is operative in a rapid manner to provide a rapid launch action.
U.S. Pat. No. 4,475,303 issued to Ribas et al. sets forth a PAD FOR LAUNCHING TOY VEHICLES ONTO A TRACK having a plate provided with an annular runway on which vehicles are placed. The launcher further includes a turnstile having arms which separate the toy vehicles and provide a stop for them. As the turnstile rotates, successive toy vehicles are launched onto the track.
U.S. Pat. No. 2,546,917 issued to Bergen and U.S. Pat. No. 4,267,661 issued to Hanson set forth further examples of turnstile type launching devices.
U.S. Pat. No. 3,908,989 issued to Meyer sets forth a SKILL GAME UTILIZING TRACKS AND VEHICLES in which a continuously operating self-propelled playing piece is utilized in a three dimensional obstacle course having simulated hazards thereon. A travel path is defined which must be successfully traversed or completed by the playing piece from a starting point to a completion point. A substantial number of prior art tracksets have been provided which utilize a bridge within a track set constructed to lift and carry a toy vehicle upwardly and forwardly to traverse the bridge span. Examples of such bridge lifting toys are found in U.S. Pat. No. 3,613,306 issued to Toshikatsu; U.S. Pat. No. 3,589,064 issued to Takayuki and U.S. Pat. No. 4,221,076 issued to Ozawa. Similar climbing vehicle toy tracksets are shown in U.S. Pat. No. 4,068,402 issued to Tanaka and U.S. Pat. No. 4,254,576 issued to Matsumoto et al.
U.S. Pat. No. 4,185,409 issued to Cheng and U.S. Pat. No. 3,359,920 issued to Iammatteo set forth examples of toy vehicle track apparatus which utilize a “teeter-tatter” or “see-saw” track segment supported in a pivotal fashion upon a fixed base.
U.S. Pat. No. 4,979,926 issued to Bisceglia; U.S. Pat. No. 4,109,412 issued to Saito; U.S. Pat. No. 4,661,080 issued to Goldstein et al. and U.S. Pat. No. 1,661,429 issued to Jade set forth examples of toy vehicle tracksets having a stunt device which includes a movable bridge.
While the foregoing described prior art devices have to some extent improved the art and have in some instances have enjoyed commercial success, there remains nonetheless a continuing need in the art for ever more interesting and amusing toy vehicle trackset stunt devices.
Accordingly, it is a general object of the present invention to provide an improved toy vehicle trackset. It is a more particular object of the present invention to provide an improved toy vehicle trackset having pneumatically actuated stunt devices.
The present invention provides a toy vehicle trackset having articulated or movable stunt elements which are moved by pneumatic actuating devices. Typical pneumatic actuating devices include an expandable cylinder and piston combination having a piston rod coupled to the movable device. In the present invention, a simple compressible air bellows is utilized as an air source and is coupled to the pneumatically activated devices by a flexible hollow tube. As a result, the user is able to activate a chosen stunt device by simply compressing the bellows coupled thereto. As the user compresses the bellows, the stunt device is actuated.
In accordance with the present invention, there is provided a pneumatic stunt device for use in combination with a toy vehicle and toy vehicle trackset, the pneumatic stunt device comprising: a support frame; a movable stunt element having a toy vehicle receiving portion movable between a first position and a second position; a pneumatic actuator coupled to the support frame and the movable stunt element; and a collapsible air bellows coupled to the pneumatic actuator, the air bellows, when compressed, causing the pneumatic actuator to move the movable stunt element from the first position to the second position such that a toy vehicle on the toy vehicle receiving portion is thrown into the air.
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:
By way of overview, the present invention bellows actuated stunt device utilizes a support frame upon which a toy vehicle track is joined. A stunt device including one or more movable components for altering the travel path of a toy vehicle traversing the coupled track is actuated by an air unit such s an expandable air cylinder and piston combination. The air unit is further coupled to an elongated flexible hollow tube which in turn is coupled to a collapsible air bellows. The user is able to actuate the stunt unit by compressing the air bellows. Examples are shown of different types of air driven units constructed in accordance with the present invention.
Trackset 10 further includes a booster 15 fabricated in accordance with conventional fabrication techniques which accelerates a toy vehicle passing downwardly upon ramp 23. Trackset 10 further includes a flexible multiple apertured panel 16 which in turn is supported by an adjustable support 17. The remainder of trackset 10 is coupled by a track segment 19 coupled to panel 16 and forming a U-Shaped portion together with a straight track segment 20. Track segment 20 is coupled to track segment 21.
Track segment 21, loop portion 22 and ramp 23 are fabricated to provide a trackway which is highly flexible in use and readily adjustable to a variety of curves, loops and twists. Thus, for example, ramp 23 is formed of a track segment 18 comprising an elongated frame 33 supporting a plurality of guide rail posts such as posts 34 and 35. Posts 34 and 35 are supported along each side of frame 33. A pair of flexible generally rod-like rails such as rails 36 and 37 are secured within posts 34 and 35 as well as the remaining posts along frame 33. The utilization of frame 33 together with supporting posts such as posts 34 and 35 are flexible guide rails such s guide rails 36 and 37 provides a track structure which facilitates bending the resulting track into a variety of curves, loops, twists and the like which are maintained in shape due to the secure attachment of guide rails 36 and 37 on each side of the track frame. In the preferred fabrication of the track segments, the fit and attachment of the guide rails utilizes an extremely tight snap-fit attachment for secure holding of guide rails. Conversely, the positioning of the guide rails after the track frame has been shaped as desired allows the snapped in guide rails to maintain the curvature or twist or other shaping of the track segment.
Loop portion 41 and loop portion 44 of trackset 40 are fabricated in the above-described manner in which a track frame supports a plurality of posts which in turn are secured to a pair of flexible guide rails. It will be noted by examination of

In operation, as a toy vehicle speeds down track segment 85 toward stunt device 80, the user attempts to time the compression of bellows 81 by pressing downwardly on bellows 81 in the direction indicated by arrow 87. The resulting air compression as bellows 81 is compressed is coupled by tube 82 to air cylinder 88. Air cylinder 88 expands drawing bridge element 84 to the raised position shown in
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.
