Abstract

A toy apparatus is disclosed in which a launcher is utilized to propel a wheel. The launcher comprises an output shaft upon which the wheel is mounted. The shaft is rotatably driven by a gear train with the input gear thereof being connected to a slidable gear rack. The gear rack is hand manipulated to slide within a guideway formed in the launcher. The input gear is floatingly mounted within the launcher to positively drive the gear train in the forward direction, when the gear rack travels in one direction along the guideway, and to move out of engagement with the gear train when the gear rack moves in the other direction along the guideway. This uncoupling movement enables the gear rack to repeat its drive cycle while the gear train is still moving in the forward direction. In this manner, the gear rack need not be completely withdrawn from the guideway to repeat its drive cycles. These repeated drive cycles greatly increase the rotational speed of the output shaft before actual launching. A wheel ejector is pivotally mounted adjacent the output shaft and is slidingly coupled to the gear rack to pivot and force the wheel off of the shaft when the gear rack is finally withdrawn completely from the guideway.

sum 3 OF 4 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to toys and more particularly to amusement devices for launching a toy vehicle.

2. Description of the Prior Art Toys which are adapted to be launched into movement have long been popular with children of all ages.

One of the oldest toys of this type is the top. The conventional top is given its rotary impetus by means of a helically threaded shaft acting on a cammed bore located on the main body of the top. Another method of applying a rotary impetus to a top, besides merely twirling ones fingers upon a small shaft portion of the top, is to wind a string around the shaft of the top and quickly pull it away.

Another method of applying a rotary impetus to a toy top or other rotary toys is to utilize a rack and pinion drive mechanism. In this type of device, an elongated rack is slidingly positioned within a slotted guideway, with the teeth of the rack engaging a pinion mounted within the guideway. To operate the apparatus, the rack is quickly pulled out of the slotted guideway to rotate the pinion at a high rate of speed. If the toy is a top, the pinion is integral with the top and the rotary motion of the pinion is transferred to the top. If the toy is a small vehicle, such as a toy racer, the pinion is rotatively mounted in the vehicle to be drivingly connected to the wheels of the vehicle. After the pinion is rotatably driven up to speed, the vehicle is placed by hand onto a flat surface to be driven by the drive wheels.

A major shortcoming with such an apparatus is that the gear rack can only travel through the guideway a single time for each drive cycle. No means are provided to uncouple the pinion gear from its drive mechanism to enable the gear rack to reverse its direction in the guideway to get back to the starting position to repeat the drive cycle. Quite often the speed of the pinion is not sufficiently high enough to drive the vehicle an appreciable distance. Because the drive cycle cannot be repeated once the pinion is rotating, the drive mechanism must be completely stopped to enable the rack to be inserted within the guideway to repeat the entire procedure.

Another shortcoming with such an apparatus is that the vehicle must be placed on the ground by hand, rather than being automatically launched by the launching device. Any automatic launching combined with the gear and rack drive has never been accomplished before, particularly with any type of repeatable gear and rack drive.

SUMMARY OF THE INVENTION The present invention obviates the above-mentioned shortcomings by providing a launching apparatus having a gear rack and pinion drive in which the gear rack can repeat its drive cycle to greatly increase its rotary speed. The apparatus also includes an ejector which automatically launches the vehicle from the apparatus when the vehicle reaches its desired speed.

The apparatus comprises a launcher having an output shaft adapted to receive a wheel. The shaft is rotatably driven by a gear train with the input gear opening into a guideway. A hand manipulated gear rack is adapted to be slidably inserted within the guideway to drivingly engage the input gear. The input gear is floatingly mounted within the launcher to positively drive the gear train in the forward direction when the gear rack travels in the one direction, and to move out of engagement with the gear train when the gear rack moves in the other direction. The ejector comprises a spring biased fork pivotally mounted on the launcher adjacent the output shaft and is slidingly coupled to the gear rack to pivot and force the wheel off of the output shaft when the gear rack is finally withdrawn completely from the guideway.

An advantage of the present invention is that the gear rack can repeat its drive cycle without withdrawing from the apparatus and while the gear train is still moving in the forward direction these repeated drive cycles greatly increase the rotational speed of the output shaft before actual launching. Moreover, this repeated drive cycle operation is akin to revving up" a motor while waiting to start a race. Such an operation is highly amusing to children.

Another advantage of the present invention is that the wheel remains secured during this revving cycle and is only released upon complete withdrawal of the gear rack from the guideway.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, FIG. 1 shows a toy launcher apparatus 10 in the process of being actuated to launch a wheel 20.

The toy launcher apparatus 10, more clearly illustrated in FIGS. 2-7 comprises a rear housing 11 and a front housing 12 united to form a compartment 13. A handle 14 is integrally formed with the rear housing 11 and is dimensioned to receive the hand grip of the operator. (See FIG. 1).

A shaft is journaled within the side walls forming the rear and front housing 11 and '12. A hexagonal portion of the shaft extends through the front housing wall 12 to receive and support the wheel 20. An output gear 16 is integrally mounted on the portion of the shaft 15 located within the compartment 13. The gear 16 is adapted to engage with an intermediate gear 17 mounted on a shaft 18 which, in turn, is journaled within a pair of elongated slots 21 formed in the housing walls 11 and 12. The shaft 18 further includes an input pinion 22 integrally mounted thereon for rotation with the intermediate gear 12.

The input pinion 22 is positioned to partially extend into a slot or guideway formed within the compartment 13. As shown in FIG. 4, the guideway is formed by two windows 24 and 25 formed on the mating peripheral edges of the housing members 11 and 12. The guideway functions to slidably receive a gear rack which is adapted to engage the input pinion 22 for imparting a rotary motion thereto. The one end of the gear rack 30 includes a handle 31 which is adapted to be gripped by an operator (see FIG. I) for pulling the gear rack 30 out of the guideway.

The wheel 20 is preferably fashioned in the form of a miniature automobile tire which includes a pair of hubs 32 and 33 integrally joined within the wheel 20 to form a unitary wheel assembly. The hub 33 includes a cylindrical center portion 34 having a hexagonal aperture formed therein for receiving the hexagonal portion of the shaft 15. An annular flange 35 is formed on the extremity of the center portion 34. The function of the flange 35 will be described hereinafter.

A spring biased wheel ejector is adapted to be pivotally mounted on the front housing 12 for urging the wheel 20 off of the shaft 15. The wheel ejector 40 comprises a fork 41 mounted on the outside of the housing 12 and extending through a slot 42 formed on the housing 12. The interior end of the fork 41 is in tegrally connected to a pivot pin 43 which is journale'd within a pair of bearing mounts 44 formed on the interior side of the front housing wall 12. The outer end of the fork 41 extends across the shaft 15 and further includes a transverse hook 45 which extends perpendicularly therefrom for engagement with the flange 35 of the wheel 20. A spring 46 is mounted on the pivot pin 43 with one end thereof biasingagainst the housing wall 12 while the other end is biased against the interior side of the fork 41. An arm 47 is also integrally formed with the pivot pin 43 and is adapted to extend into the compartment 13 across the guideway to slidingly engage the gear rack 30.

OPERATION To operate the launcher apparatus 10, the gear rack 30 is inserted through the window 21 and moved entirely through the guideway to extend out of the rear window 25. As the gear rack 30 moves through the guideway, it engages the input pinion 22 to impart a rotary motion thereto in the clockwise direction as shown in FIG. 5. Because the input pinion 22 is supported in the elongated slots 21, the force of the gear rack 30 on the input pinion 22 forces the shaft 18 forwardly to carry the intermediate gear 17 out of engagement with the output gear 16. (See FIG. 5). As a result, no rotary motion is transmitted to the gear train when the gear rack 30 is moved through the guideway in the forward direction.

As the gear rack 30 is inserted and moved forwardly through the guideway, it also contacts the arm 47 to pivot it and the fork 41 in a clockwise direction as shown in FIG. 6 against the bias of the spring 46. At the end of this movement, the hook 45 is positioned to engage the flange 35 of the wheel 20 to secure the wheel 20 against axial movement as it is mounted on the hexagonal shaft 15.

At this point, the gear rack 30 is in the ready position to impart a rotary movement to the wheel 20. This is accomplished by simply pulling the gear rack 30 rearwardly to rotate the input pinion 22 in the counterclockwise direction as shown in FIG. 4. This movement also creates a rearward force on the input pinion 22 to cause the shaft 18 to move rearwardly to enable the intermediate gear 17 to engage the output gear 16. (See FIG. 4). As a result, the rotary motion of the input pinion 22, caused by the rearward movement of the gear rack 30 transmits a rotary movement through the gear train to rotate the hexagonal shaft 15 and the wheel 20 mounted thereon.

As the end of the gear rack 30 moves past the arm 47, the retaining force on the arm 47 is released and the spring bias of the spring 46 causes the arm 46 and the fork 41 to pivot in the counter-clockwise direction as shown in FIG. 7. This movement causes the hook 45 to be disengaged from the wheel flange 35 and the fork 41 to force the freed wheel 20 off the shaft 15. Once the wheel 20 is moved off the shaft 15, it drops to the ground and its rotary momentum enables it to travel in the forward direction.

This operation was described for only one pull of the gear rack 30. However, if it were desired to impart a faster rotational speed to the wheel 20 before ejection, the operator would not withdraw the gear rack 30 completely out of the guideway past the arm 47. Instead, after partially pulling the gear rack 30 through the guideway to start the wheel moving, the operator moves the gear rack 30 forward again to the initial position. This forward force on the input pinion 22 causes the shaft 18 to again move forward to disengage the gear 17 from the gear 16 as shown in FIG. 5. This uncoupling of the gear train enables the shaft 15 and wheel 20 to continue rotating in the forward direction while the gear rack 30 is returning to the start of its drive position.

After reaching this position, the operator then pulls on the gear rack 30 to again move it rearwardly. As before, this rearward force on the input pinion 22 causes the gear train to again be coupled to transmit a rotary movement to the wheel 20.

As can be seen, the drive cycle of the gear rack 30 can be repeated as often as desired to increase the rotational speed of the wheel 20. When the desired speed is reached, the operator pulls the gear rack 30 completely out of the guideway to enable the fork 41 to force the wheel 20 off the shaft 15. As can be seen, the wheel 20 remains secured to the shaft 15 and cannot become accidentally disengaged or launched until the operator desires to do so.

It should be noted that various modifications can be made to the apparatus while still remaining within the purview of the following claims. For example, noise making devices can be connected to the moving parts of the apparatus to enhance and simulate the roaring sound of a motor. Moreover, any standard toy vehicle can be modified to be launched by the launcher of the present invention.
