The connection between the spring motor and the driven wheel includes an automatic clutching gear which operatively disengages the motor from the driven wheel automatically in response to movement of the crank arm while storing energy in the spring motor, and which operatively engages the motor and driven wheel automatically in response to releasing the energy stored in the motor. The vehicle is in the form of a contemporary motorcycle.
10 Claims, 6 Drawing Figures TOY VEHICLE AND ASSOCIATED CONDITIONING MEANS THEREFOR BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to toy devices and more particularly to driven vehicle type toys operated by constant torque spring motors, or the like.
There are many different forms of driven vehicles or inertia toys which operate, or have portions which operate, on the release of energy stored in a momentum imparting component. Generally speaking, this oftentimes is accomplished by storing energy in a constant torque spring type motor which operates through gears or linkages to a driven component of the vehicle.
Such toys of the character described are well received in that they are simple in structure and operation and, with sufficient power or energy, dramatic in operation. The principal object of this invention is to meet the continuing need and desire in the art for improved toys of the character described.
In the exemplary embodiment of the invention, a toy vehicle and external manipulatable conditioning means is provided for winding the vehicles motor and to permit the vehicle to be driven over a supporting understruture on release of energy stored in the motor. A supporting frame is provided with a platform or stand portion on which the vehicle is positioned, and a crank arm is movably mounted on the frame. The crank arm is connected through coupling means to a spring torque motor on the vehicle which is operatively connected to motive means, such as a wheel of the vehicle, for moving the vehicle. The motor is cnoditioned (i.e., energy is stored therein as it is wound) in response to movement of the crank arm on the external supporting frame. Actuating connecting means is operatively connected between the motor and the driven wheel and includes automatic clutch means for operatively disengaging the motor and the driven wheel automatically in response to movement of the crank arm to store energy in the motor and for operatively engaging the motor and driven wheel automatically in response to releasing the energy stored in the motor.
The actuating connecting means includes a gear train between the motor and the driven wheel and the automatic clutch means includes a gear member mounted for free movement in a direction transversely of its axis of rotation for movement out of engagement with a gear on the driven wheel as the crank arm conditions the spring motor and for movement into engagement with the gear on the driven wheel under the momentum of the energy released from the springmotor to the other gears of the gear train.
The exemplary form of vehicle simulates a motorcycle having a body portion on which the spring motor, gear train, clutch gear, coupling means and driven wheel are mounted, with a front wheel for the motorcycle being disposed on the front end of an elongated resiliently mounted shaft pivotally mounted to the vehicles body portion at the front top areas thereof.
Other objects, features and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings in greater detail, a toy vehicle, generally designated 10, is provided in the shape of a motorcycle and is operatively associated with an associated external manipulatable conditioning means, generally designated 12, on which the vehicle may be positioned, as shown in FIG. 1, so that the motor means thereof may be conditioned by storing energy therein in response to movement of a crank arm 14. The crank arm has a handle portion 15 and is pivotally mounted by means of a shaft 16.
More particularly, the external conditioning means 12 includes a supporting frame having an upstanding housing portion 20 on which the crank arm shaft 16 is pivotally mounted, and a generally horizontally disposed lower stand or platform portion 22 on which the vehicle 10 may be positioned. Power transfer means between the crank arm 14 and the vehicle 10 includes a disc-shaped gear member 24 mounted within the upright housing portion 20 for conjoint rotation on the crank arm shaft 16. Gear 24 is in meshed engagement with a smaller diameter gear member 26 to provide for increased mechanical advantage and an increase in revolutions. The gear member 26 is mounted for rotation on the upright housing portion 20. A first coupling member 28 is secured to the gear 26 for conjoint rotation therewith and is disposed on the exterior of the upright housing 20. The coupling member 28 is provided with a female socket or connection 30.
The vehicle 10 is formed in the shape of a motorcycle having a body portion formed by a pair of spaced support plates 32a and 32b on top of which is mounted a seat portion 34 (FIG. 1). A rear wheel, generally designated 36, is rotatably mounted by means of a rear axle 38 to the body support plates 32a, 32b. The rear wheel is the motive means for the vehicle. A rounded recess 39 is formed on the platform portion 22 to properly position the vehicle for conditioning the vehicle by rotating the crank arm 14. A front wheel 40 for the vehicle is mounted on the front end of elongated shaft means, generally designated 42, which extends forwardly and downwardly from the top front of the body support plates 32a and 32b of the vehicle. The shaft means 42 actually comprises a pair of generally parallel shaft members 44 extending downwardly from an enlarged pivot boss 46, with the front wheel 40 pivotally mounted between the shaft members 44. The pivot boss 46 is pivotally secured between the body support plates 32a, 32 b. Handle bar means 48 extend upwardly from the pivot boss 46. As best seen in FIGS. 2 and 5, a pair of wire springs 50 are wrapped around projections 52 on the sides of the pivot boss 46,'with embracing portions 54 of the wire springs seated on top of the shaft members 44 to urge the shaft means 42 and front wheel 40 downwardly. A stop rod 56 (FIG. 3) defines the lower limit position of the shaft means 42 and wheel 40. The wire springs 50'provide resiliency for the vehicle whereby the front wheel may be forced upwardly by irregularities in the surface over which the vehicle is traveling, generally in the direction of arrow A (FIG. 3).
The motor means for the vehicle of the present invention comprises a spring band 58 wound on a core 60 (FIG. 3) which is fixed to a shaft 62 rotatably mounted between the body support plates 32a, 32b. The core 60 comprises a take-up drum for the spring to move the vehicle as described hereinafter as the spring is wound back onto the take-up drum. The opposite end of the spring 58 is secured, as by a screw 64 (FIG. 4), to a second drum 66 which is rotatably mounted between the body support plates 32a, 32b by means of a shaft 68. The shaft 68 extends through the support plate 32a (as best seen in FIGS. 2 and 4) and has an irregularly shaped male coupling portion 70 which is insertable into the complementarily shaped socket 30 of the coupling means 28. Thus, in order to store energy in the spring motor (comprising spring 58), the vehicle is placed in position on stand portion 22, as shown in FIGS. 1 and 2, with the coupling means 70 and 28 interconnected, and the crank arm 14 is rotated to wind the spring 58 onto the drum 66. When the spring is completely wound off of the drum 60, a stop spring leaf 72 (FIG. 3) mounted on a shaft 73 falls into a recess 74 on the drum 60 to prevent further winding of the spring off of the drum 60 to prevent damage to the connection between the spring and the drum. A second stop spring leaf 76 also is provided for dropping into a recess 78 on the drum 66 when the spring returns tothe take-up drum 60 to avoid damaging the connection between the spring and the'drum 66.
Actuating connecting means is operatively connected between the motor spring drum 66 and a rear wheel gear member 80 mounted on the rear axle 38 for rotation with the rear wheel 36, and comprises a gear train, generally designated 82. The gear train includes a disc gear 84 mounted for conjoint rotation with the spring drum 66 and which is in mesh with a smaller diameter gear 86, providing increased mechanical advantage and increased revolutions, the gear 86 being mounted on a shaft 88 for conjoint rotation with a larger disc gear 90. Disc gear 90 is in mesh with a smaller diameter gear 92, providing for further increased mechanical advantage and increased revolutions, the gear 92 being secured for conjoint rotation with a larger diameter gear disc 94. Gears 92 and 94 are mounted on the spring drum shaft 68 for free rotation relative thereto, whereby the disc gear 94 may be rotated at a faster rate of speed than the gear disc 84 (on the same shaft) due to the step down gears 86 and 92.
The gear train 82 includes an automatic clutch gear 96 which is mounted on a lever member 98 for movement generally transversely of the axis of rotation of the gear 96 into and out of engagement with the rear wheel gear 80. More particularly, the lever 98 is pivotally mounted on the shaft 68 which is common to the gears 84, 92 and 94 as well as the spring drum 66. Thus, the gear 96 is maintained in constant meshed engagement with the disc gear 94. With the arrangement as shown and described above, the clutch gear 96 thus comprises a momentum clutch whereby it moves out of engagement with the rear wheel gear as the motor spring 58 is wound onto the spring drum 66. This occurs because the disc gear 94 rotates in the direction of arrow B (FIG. 6) as the motor spring 58 is wound onto the spring drum 66 by the crank arm 14. Rotation of the disc gear 94 in the direction of arrow B tends to force the clutch gear 96 downwardly in the direction of arrow C out of engagement with the rear wheel gear 80. A slot 100 is provided in the body support plate 32b through which a pin shaft 102 of the clutch gear 96 extends to accommodate the movement of the clutch gear. When the vehicle is moved out of engagement with the crank arm coupling means 28, and the energy stored in the motor spring 58 is released to permit the motor spring to return to its stored position on drum 60, the momentum of the rotating gears (caused by the energy in the spring, with the disc gear 94 rotating opposite the direction of arrow B (FIG. 6)), forces the clutch gear 96 upwardly opposite the direction of arrow C and into engagement with the rear wheel gear 80 to drive the same and move the vehicle over an understructure such as a floor, the ground, or the like.
It will be noted that the rear wheel 36 is oversized relative to the front wheel 40 and includes an outer tread portion 104. The outer tread portion 104 may be fabricated of rubber or like material which has a greater weight per volume than the framework 106 of the rear wheel, which may be fabricated of plastic or the like. In addition, outrigger wheels 108 are provided, protruding outwardly from the body support plates 32a, 32b to provide stabilization for the vehicle.
The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom as some modifications will be obvious to those skilled in the art.
