'Cl. 272--31 Int. Cl. A63g 18/02, 29/08, 18/16 6 Claims ABSTRACT OF THE DISCLOSURE This invention relates to toy apparatus and particularly to mechanical facilities for controlling the tilting operations of a supporting platform to implement the traveling operations of toy vehicles.

A variety of devices are presently available for controlling the traveling operation of toy racing cars, airplanes and other such vehicles. Such devices often need a large number of delicate parts and, in many instances, are costly and complex in construction and operation. These factors tend to limit the widespread marketability and use of the control devices.

It is therefore an object of my invention to provide simple and economical facilities for controlling the traveling operations of toy vehicles.

Another object is to reduce the number of parts needed for such control facilities and particularly to provide durable structural elements.

These and other objects are attained in accordance with specific exemplary embodiments of my invention wherein simple and economical facilities are furnished for manually operating a platform, or track, member to a plurality of tilted positions to control the traveling movement of toy racing cars and airplanes by gravity operated means. In addition, the structural elements utilized for achieving the tilting operations and vehicle movements are durable and minimal in number.

Specifically, each illustrative embodiment of my invention comprises a circular base member which is suitable for placement on a floor and for supporting the other structural elements. A post member is centrally mounted on an upper surface of the base member and extends vertically upward therefrom. According to one feature of my invention, the upper end of the post member is attached to a swivel means which advantageously may comprise a spring elementior ball joint device. The swivel means is pivotally affixed to an attaching body upon which a tiltable platform, or track, member is mounted by means of suitable fasteners. Advantageously, I provide a plurality of different platform members for mounting individually on the attaching body and for tiltable positioning to control the traveling movement of the toy vehicles.

In one exemplary embodiment of my invention, the last-mentioned platform member is oval in shape and includes a lower surface fastenable to the attaching body of the swivel mounting arrangement on the post memher. An upper surface of the platform comprises a plurality of slotted tracks which are suitably spaced from each other for the traveling movement of toy racing cars around the tracks. Each of these racing cars comprises a plurality of strut members for slidably engaging the slotted tracks which direct the cars about the upper platform surface. A manually operable tilt control handle is secured via a coupling shaft to travel indicator apparatus which is aflixed to a peripheral side of the platform for controlling the tilting action of the platform. The manipulation of the control handle enables a translation of the platform on its swivel mounting into a tilted position whereby the cars engaged with the slotted tracks travel towards a low part on the tilted, or included, track. Further circular tilting of the platform causes each car to continue its movement around the track.

Another illustrative embodiment of my invention advantageously comprises a circular platform member which has a lower surface mountable on the attaching body of the swivel mounting arrangement. A central point on the upper platform surface is secured to a first end of a L shaped coupling shaft which extends upwardly therefrom. A tilt control handle is affixed to the other end of the shaft for manipulation whereby the circular platform is tilted. A pair of retaining rings are positioned on the coupling shaft in vertical planes above the rest position of the platform to define the upper and lower excursion limits of a bearing device which is located intermediate thereto on the shaft and is rotatably attached thereabout. The bearing device is affixed to one end of a semiflexible cable, the other end of which is connected by means of an attaching device to a toy racing car or airplane.

In accordance with another aspect of my invention, a weighted Wheel is used to cooperate on the upper platform surface for controllably moving the cable and hence the car or airplane around the circular platform. The wheel comprises an aperture through which the cable extends. It also has a peripheral, or circumference, surface which is ridable by gravity on the upper surface of the platform during the tilting thereof.

Accordingly, the tilt control handle can be manipulated for translating the circular platform on its swivel mounting to a plurality of tilted positions whereby the wheel is urged on the upper surface of the platform toward a low part thereof and concurrently it carries the cable along with it to operate the car or airplane in a desired path of travel. The structure of my invention enables the car or airplane to be motorless or motor-powered. More particularly, the structure enables a self propelled airplane to take-off, maneuver in flight and to land. A substantially rigid cable may replace the semifiexible cable to perform the same flight operations for a motorless airplane. In addition, the vehicles also may travel in circular paths when the circular platform is in its rest posi tion and to deviate therefrom by effectively decreasing or increasing the distance between the central point on the upper platform surface and the extended end of the cable by the tilting action of the platform.

The foregoing and other objects, features and advantages of my invention will be more clearly understood from a reading of the following description of illustrative embodiments thereof with reference to the drawings in which:

FIG. 1 is a perspective view of the entire assembly comprising a tilt control means including a spring memher attached to a circular platform for controlling the paths of travel of a pair of toy racing cars coupled to the exemplary facilities of my invention by a semiflexible cable;

FIG. 2 is a plan view of tilt control apparatus with a ball joint mechanism for tilting a slotted track to control the travel of weighted cars about the slotted track segments;

FIG. 3 shows the assembly of FIG. 1 used for controlling the travel of an airplane instead of a car, and further displays the various tilting positions which the circular platform assumes under control of the tilt control means; and

FIG. 4 shows the apparatus utilized for fastening the semiflexible cable to the toy airplane of FIG. 3.

As shown in FIG. 1, the illustrative embodiment of my invention comprises a circular base member 1 having a post rod 2 mounted centrally thereon and extending vertically upward therefrom. A spring device 3 is cooperatively joined and associated with an upper end of post 2 and is aflixed to an attaching body 4. The latter is shown through a sectional view of a circular platform member 5 and is secured to a center point on the lower surface 6 of member 5 by means of suitable fasteners 7 projecting through apertures (not shown) in body 4. Thus, platform 5 is spring mounted to the rod 2 for tilting movement.

An L shaped coupling shaft 8 is secured at one of its ends to a center point on a flat upper surface 9 of platform 5. The other end of shaft 8 is attached to a tilt control handle 10 which is movable for cooperating with shaft 8 to tilt platform 5 from its rest position as defined by the body 4 and spring 3. Shaft 8 extends vertically upward and horizontally outward from the center point of surface 9 so that a vehicle may travel without interference from the shaft 8 or the person operating the handle 10.

The shaft 8 is of circular cross-section and extends through an aperture 11 in a bearing ring device 12 for enabling that device freely to rotate about shaft 8 during the travel of a vehicle. Device 12 is interposed on shaft 8 between upper and lower retaining elements 13 and 14 which are affixed on shaft 8 to limit the upward and downward movement of device 12 on shaft 8. A semiflexible cable 15 is secured at one of its ends to a peripheral surface 16 of device 12. Cable 15 is also extended through an orifice 17 in a circular weighted wheel 18 and its other end is fastened to a fastener means 19 associated with a toy racing car 20. Wheel 18 is13 so that its peripheral surface 21 rests by gravity on the upper surface 9 of platform 5 during the movement of car 20.

A second racing car 22 is pivotally connected to the car a suitable connecting rod 23 which extends through cooperating apertures (not shown) in the facing sides of the cars 20 and 22 and with the rod ends (not shown) comprising, for example, ball elements for the pivotal movement of the cars with respect to each other. This pivotal cooperation enables each one of the cars to pass the other one during the traveling movement.

In FIG. 1, racing cars 20 and 22 are depicted in a cooperating relationship with the cable 15 for movement in a desired path of travel on a floor surface under control of the tilt control facilities of my invention. FIG. 3 illustrates an airplane 24 instead of a racng car fastened to the cable 15 by means of the fastening means 19 for the captive flying of that airplane. Referring to FIG. 4, the fastening means 19 is shown comprising an attaching block 25 secured to the cable 15. A control wire 26 is extended through an apertured segment 27 of block 25 and spring clip end members 28 and 29 of the wire 26 extend into apertures 30 and 31, respectively, in a wing 32 of the airplane 24 for fastening the cable 15 to that airplane. The block 25 is locked at a prescribed position along the length of wire 26 by a set screw arrange ment 33 in block 25. A racing car, such as car 20 of 4 FIG. 1, is fastened to cable 15 with fastener means 19 by inserting the spring clip end members 28 and 29 into cooperating apertures (not shown) in the facing sde of the car body.

Turning now to the operation of the exemplary embodiment of my invention as set forth in FIG. 1, the movement of the tilt control handle 10 enables the coupling shaft 8 to translate the circular platform 5 into a tilted position on its mounting comprisng body 4 and spring 3 for urging the upper surface 9 of platform 5 against the peripheral surface 21 of the Weighted wheel 18, whereby wheel 18 commences to rotate by gravity on the surface 9. The rotation of wheel 18 causes its wall associated with and defining the orifice 17 to move the semiflexible cable 15. The latter cable is secured at one end to the bearing device 12 and therefore moves circularly about the central point of the surface 9 as the device 12 rotates on the coupling shaft 8. The movement of cable 15 effects the driving of the wheeled racing cars 20 and 22 in a path on the floor surface 34-. Wheel 18 thereafter continues to rotate on the upper surface 9 for moving the cars 20 and 22 as long as the surface 9 is inclined under control of the handle 10, shaft 8 and spring 3.

Cars 20 and 22 may travel in a circular path as illustrated in FIG. 1 when the surface 9 is in a horizontal plane. The tilting of the platform 5 under control of handle 10, shaft 8 and spring 3 enables the cars 20 and 22 to travel about the depicted circular path by effectively reducing or increasing the straightness of cable 15. In addition, the cars 20 and 22 may advantageously be driven either solely under control of the apparatus of FIG. 1 or with the aid of suitable motor means (not shown) cooperating with the car wheels.

FIG. 3 depicts various tilted positions into which the platform 5 may be urged under control of handle 10, shaft 8 and spring 3. It also shows that an airplane 24, instead of a car, may be propelled by the movement of the cable 15, as previously explained. In accordance with the illustrative structure of my invention, cable 15 may may be made of a substantially nonfiexible material for the flying operations of a motorless airplane 24. Such an arrangement enables the exemplary apparatus of FIG. 3 to be operated under control of handle 10 for take-off, flight maneuvering and landing operations of airplane 24. The apparatus of FIG. 3 functions to control the movement of cable 15 for the aforementioned airplane operations in basically the same manner as previously explained with respect to the cars 20 and 22. The airplane 24 may also be self propelled under control of a suitable airplane motor means (not shown) and the apparatus of FIG. 3 may advantageously be used to control the path of fli ht over either a semi or nonflexible cable 15.

FIG. 2 shows another illustrative embodiment of my invention comprising an oval platform 35 having an upper surface 36 with a pair of slotted tracks, or guides, 37 and 38 suitably spaced from each other for directing the movement of a pair of weighted cars 20a and 22a on the surface 36. Each of the cars 20a and 22a is equipped with a pair of struts 39 and 40 which slidably interfit with the associated track 37 or 38 for the direction of the car around the track. A lower surface 41 of platform 35 is centrally mounted upon an attaching member 42 by means of fasteners 7a. The member 42 is also swivelly joined to a ball joint device 43 for the tilting movement of the platform 35. The ball joint device is cooperatively secured on an upper end of a post rod 2a, the lower end of which is affixed centrally on a circular base member 1a.

A control indicator apparatus 44 is secured to a peripheral side member 45 of platform 35. The apparatus 44 includes a marked scale 46 with speedometer type graduations together with a cooperating weighted pendulum indicator 47 which provides suitable speed indications for the cars 20a and 22a during their movement on platform 35 due to the latters tilted action. A tilt control handle 48 is secured to a coupling shaft 49 afiixed to the indicator apparatus44 for controlling the tilting of platform 35. In addition, a mask member 50 is mounted about the shaft 49 for masking of the pendulum indicator 47.

After the cars a and 22a have been placed upon platform 35 and the struts 39 and 40 have slidably engaged the respective track slots 37 and 38, the cars can be driven about the tracks. Such driving occurs by gravity and the cars move toward the lowest point of the inclined, or tilted, platform 35 when the latter is tilted under a control movement of the tilt handle 48 and shaft 49, which movement urges platform 35 to a tilted position on its mounting body 42 and swivel ball joint device 43. The cars 20a and 22a continue to move around the tracks 37 and 38 as long as they have momentum or the platform 35 provides an incline with a low part in the direction of the car movement.

According to my invention, the mounting arrangement for the platforms 5 and 35 may advantageously comprise the spring 3 or the ball joint device 43 configuration for the tilt functions. In addition, the slotted track platform 35 or the circular platform 5 with its associated tilt control facilities may suitably and facilely be interchanged and individually mounted upon the support structure comprising the attaching body 4, spring 3, post 2 and base member 1.

It is to be understood that the hereinbefore described arrangements are illustrative of the application of principles of my invention.
