Abstract

A mechanized ball includes a hollow sphere having a removable hatch through which a powered ball driving unit can be placed within the sphere and removed therefrom. The ball driving unit can be electrically or mechanically powered and may be in the form of a single powered driving wheel or a self-contained four wheeled toy vehicle. The vehicle may be guided within the ball by a strut and/or a spring device which contacts an interior part of the ball. In some species the ball may be steered by a weight which is moved back and forth along a dual helical groove on a diametral support from which a single powered drive wheel is suspended.

Claims

1. A mechanized toy ball comprising a spherical shell having inner and outer concentric surfaces, and a mechanically guided friction drive means including a power source and a motor for the ball contained wholly within the shell and having a rotary drive element in driving contact with said inner surface, and said drive means including means for imparting rolling directional movement to the shell, said inner surface being spherical, and the last-named means comprising a sphere fixed within the shell in spaced concentric relationship to said inner surface and guidingly engaging the friction drive means within the shell.

2. A mechanized toy ball as defined in claim 1, and the last-named means also having an internal annular guideway within the shell for said drive means.

3. A mechanized toy ball as defined in claim 2, and said annular guideway comprising a channel ring fixed within the spherical shell in concentric relation therewith.

4. A mechanized toy ball as defined in claim 2, and said annular guideway comprising spaced parallel guide flanges secured to the shell and projecting inwardly of the shell interior surface.

5. A mechanized toy ball as defined in claim 1, and the friction drive means comprising a battery powered toy car.

6. A mechanized toy ball as defined in claim 1, and the friction drive means comprising a rotary drive element climbingly engaging the interior of the shell.

7. A mechanized toy ball as defined in claim 6, and said rotary drive element comprising a gear, and the interior of the shell having gear teeth on an annular path around the shell engaging said gear.

8. A mechanized toy ball as defined in claim 1, and said spherical shell being formed in two separable sections having interengaging coupling means.

9. A mechanized toy ball as defined in claim 8, and said friction drive means including a windable spring motor.

10. A mechanized toy ball comprising a spherical shell having inner and outer concentric surfaces and a mechanically guided friction drive means including a power source and a motor for the ball contained wholly within the shell and having a rotary drive element in driving contact with said inner surface and said drive means including means for imparting rolling directional movement to the shell having a diametrical shaft mounted within the shell for rotation relative thereto and having a dual spiral groove, a self-reversing pendulum weight slidably mounted on said shaft having driven engagement with said groove for driving it therealong and reversing its direction at the end of said shaft, a lateral arm fixed to and projecting from one side of said shaft and said friction drive means being carried by said arm.

11. A mechanized toy ball as defined in claim 10, said rotary drive element comprising a friction drive wheel engaging said inner surface and said friction drive means further including an electric drive motor drivingly connected with said wheel, a battery compartment within the shell, bearings for said rotary diametrical shaft on the shell and battery compartment and slip ring electrical connecting means within the shell between said electric drive motor and battery compartment.

12. A mechanized toy ball comprising a spherical shell having inner and outer concentric surfaces and a mechanically guided friction drive means including a power source and a motor for the ball contained wholly within the shell and having a rotary drive element in driving contact with said inner surface, and said drive means including means for imparting rolling directional movement to the shell having a diametrical shaft mounted for rotation relative to said shell with a sleeve member fixed to and extending from said inner surface and disposed around said shaft, a lateral arm projecting from one side of said shaft and said friction drive means carried by said arm, said sleeve having a dual spiral groove and a self-reversing weight slidably mounted on said sleeve, having driven engagement with said groove.

13. A mechanized toy ball comprising a spherical shell having inner and outer concentric surfaces, and a mechanically guided friction drive means including a power source and a motor for the ball contained wholly within the shell and having a rotary drive element in driving contact with said inner surface, and said drive means including means for imparting rolling directional movement to the shell, and the last-named means comprising a fixed cylindrical member within the shell on a diametrical axis of the shell and guidingly engaging the friction drive means, said drive means including a toy car having guided engagement with the periphery of said cylindrical member while driving said ball, and said spherical shell including a removable hatch portion having a spring-urged starting platform against which the body of the toy car is placed when the toy car and hatch portion are being placed in assembled relationship with the spherical shell, said ball including means for retracting said platform when in said relationship.
