6Clalrm,8Drawlngl igures MOTOR-DRIVEN ROLLING TOY SUMMARY OF THE INVENTION This invention relates to toys, and more particularly to a battery-operated rolling toy contemplated to afford considerable enjoyment to observers due to its comical and mysterious operation.

Still a further object of the present invention is to provide a toy of the type described which can be easily disassembled for replacing the batteries in the toy.
Further objects, features and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings which illustrate preferred embodiments of the present invention and in which:

FIG. 8 is an exploded view of part of switch means attached to the second embodiment.
Referring to the drawings, in FIG. 1 to 3, there is shown a rolling toy A as one embodiment of the present invention. The rolling toy A comprises a pair of interengaged, substantially symmetrical sections 10 and 11 of suitable material such as metal or plastics which form a housing 12 substantially in the form of a wheel for an automobile, two annular sections 13 and 14 of resilient material such as rubber which are respectively mounted on the outer peripheral portions of the housing sections 10 and 11 to fonn a simulated tire 15, a shaft 16 of a suitable structural material such as metal which extends axially along the central axis of the housing sections 10 and 11 and is fixed thereto by means of generally hub caplike threaded members 17 and 18 which are in threaded engagement with threaded end portions 16a and 16b of the shaft 16 and which are fitted in the central holes 19 and 20 formed in laterally outwardly extending rim portions 21 and 22 of the housing sections 10 and 1 1, respectively, and a motivating or driving unit, generally designed as 23, is enclosed within the housing 12 and is carried by and rotatable about the shaft 16.
The motivating unit 23 comprises a substantially sectorial frame 24 having a gear box 24a and symmetrically arranged battery casings 24b and carried by and rotatable about the shaft 16, an electric motor 25 mounted within the gear box 24a of the frame 24 in eccentric relation to the shaft 16, said electric motor being operatively connected to the shaft 16, through the medium of a gear train generally designated at 26,
for rotating the frame 24 relative to the housing 12, dry cell batteries 27 tightly encased by the battery casings 24b formed on the frame 24 in eccentric relation to the shaft 16, and a weight 28 which is also formed on the frame 24 in eccentric relation to the shaft 16.
The batteries 27 are electrically connected to the motor 25 via a contactor 29 and manually operable switch means 30 for controlling the operation of said motor. To change the batteries 27 in the toy, one may first remove the threaded member 18 on the side of the housing section 11 and then separate the housing section 1 1 from the other housing section 10, whereupon one opens covers 24b of the battery casings 24b thereby providing access to the batteries.
As shown in FIGS. 2 and 3, the switch means 30 is mounted on one 10 of the two housing sections and includes a switch lever 30a projecting outwardly of the housing section 10. The contactor 29 includes an insulating disk 29a fixedly mounted on the shaft 16, two annular contacts 29b and 29c fixed to one side of the disk 29a and two leaf-springs 29d and 29e in contact with the annular contacts 29b and 290 at their tip portions and which are anchored at their base portions to the rotatable frame 24. It goes without saying that switch 30, contactor 29 and motor 25 are connected to each other by lead wires in conventional manner.
The circumferential edge portion of one of the two housing sections 10 and l 1 is formed in stepped fashion as indicated at 31 so that the opposing edges of the housing sections interlock with each other. The stepped interengagement of the two housing sections 10 and 11 serves to keep the toy maintained in the form of a wheel in cooperation with the shaft 16 and threaded members 18 and 19, which secure the two housing sections 10 and 1 1 together, during use.
The gear train 26 includes a pinion 32 attached to the motor shaft 33, a gear wheel 34 and a pinion 35 attached to a shaft 36 journalled in the side walls of the gear box 24a, a gear wheel 37 attached to a shaft 38 joumalled in said side walls, a pinion 39 coaxial with the gear wheel 37 and a gear wheel 40 fixedly mounted on the central shaft 16.
When it is desired to operate the rolling toy A, the switch 30 is first manipulated to close the motor circuit. The motor 25 will then rotate causing rotation of the gear wheels 32, 34, 35, 37 and 39. This will cause the motivating unit 23 to rotate about the fixed gear wheel 40 and the central shaft 16. As the toy is positioned on a supporting surface such as a floor in an upright position by placing the peripheral surface of its tire 15 thereon, the off-center movement of the center of gravity of the motivating unit 23 will cause the housing 12 in the form of a wheel to begin rolling on the surface. In this instance, the housing 12 will rotate in a direction opposite to the direction of rotation of the unit 23.
As the toy continues rolling on the surface in an upright position and comes into collision with an obstruction such as a wall, it will overturn and rotate on the surface while describing a substantially conical path, as if a top, which has overturned and almost lost its rotational force, rotates on the supporting surface.
Then, centrifugal force will act on the motivating unit 23 and accordingly on the housing 12 as the speed of rotation of the unit 23 increases, and at the same time the frictional force between a surface-contacting portion of the tire 15 of the wheel and the supporting surface in contact therewith that acts to drive the wheel along the surface will increase. In other words, at this time, a resultant force of such centrifugal force and frictional force will act on the toy strongly. Accordingly, the toy supported on the surface with its threaded member 17 or 18 and the surface-contacting portion the sideward peripheral portion of its tire 15 will be caused to return into an upright or standing position as schematically illustrated in FIG. 4, thereby resuming its rolling movement on the surface with the tire 15 in frictional contact therewith. Thereafter, it will repeat such movements as diagrammatically illustrated in FIG. 5 which exemplifies the manner of operation of the toy.
Referring now to FIGS. 6 to 8, there is shown another embodiment B of the present invention. This embodiment B differs principally from the first embodiment A in the following points, although it is basically the same as the latter.
As clearly shown in FIG. 6, a central shaft 41 which corresponds to the central shaft 16 of the first embodiment A is of a hollow structure and extends axially along the central axis between housing sections 10 and 11. Further, the hollow shaft 41 is rotatably supported at its opposite ends 41a and 41b by inwardly extending axially positioned bosses 42 and 43 on the housing sections 10 and 11 and carries a sectorial frame 14 which constitutes part of a motivating unit 23' which corresponds to the motivating unit 23 of the first embodiment A.
The motivating unit 23 of the second embodiment includes an electric motor 25' fixed to the frame 24 and having an output shaft 33 having a pinion 32, a gear wheel 34' attached to the shaft 36, joumalled in the side walls of the frame 24 and a gear wheel coaxial with the gear wheel 34'.
In the second embodiment, the two housing sections 10 and l l are adhesively secured together at the opposing edges thereof to form a wheel-shaped housing 12. One 10 of the two housing sections is formed with a ring gear 44 which is in meshed engagement with the gear wheel 35. The other 11 of the two housing sections is provided with an opening 45 with an openable cover 46 for replacing batteries 27, and also with switch means generally indicated at 47.
' As shown in FIGS. 6 and 8, the switch means 47 includes a substantially U-shaped leaf-spring 48 which is secured to the frame 24' and which is in circuit with the motor 25' via the batteries 27 and axially displaceable pusher means 49 including a rod 50 having a disk 50' and being displaceable along the central axis of the hollow shaft 41, a rotatable cam member 51 manually operable from the outside of the housing section 1 1' and adapted to displace the rod 50 toward and away from the leaf-contact48 in cooperation with a fixed cylindrical member 52 having engaging means 52 in engagement with sloping cam surfaces 51 of the cam member 51, when manipulated.
in the illustrated second embodiment B, the portions or parts indicated by numerals l3, 14, 15', 21', 22", 24b and 31 correspond to the portions or parts 13, 14, 15, 21, 22, 24b and 31 of the first embodiment A, respectively. Therefore, to avoid repetition description will be omitted as to these parts.
In operation, when the contact 48 is depressed by manipulation of the rotatable cam member 51, it is brought into contact with a mating 48' of the motor 25' whereby the motor circuit is closed and the motor 25 is actuated, causing rotation of the gears 32', 34' and 35. This will cause the motivating unit 23' to rotate about the central axis of the housing 12 to thereby impart rotary motion to the housing 12', Thus enabling the toy B to make such comical and mysterious movements as previously mentioned in respect of the first embodiment A.
It is to be noted that the tire 15 or 15 should be made of rubber or other material which creates relatively large friction forces so that it may have sufficient resistance to sliding on the supporting surface. If the tire is'made of a material which has little or no resistance to the slippage, the toy will be unable to return to rolling position when overturned, since the frictional resistance of the tire against the supporting surface requires to be large enough to cause the toy to be righted in cooperation with the action of centrifugal force.
It is to be also notedthat, although the configuration of the housing 12 or 12 of thetoy A or B may be suitably modified as long as it takes the form of a wheel, the housing must always have on each side thereof a portion extending laterally outwardly therefrom in substantial alignment with its transverse axis in order that the toy may return to the upright position, when overturned. The length of the laterally outwardly extending portion, which acts as a support or pivot for the toy when thetoy overturns, maybe appropriately designed depending upon the diameter and the width of the wheel-shaped housing. The configuration of the portion is preferably conical or like shape.
Further, although a weight such as indicated at 28 is preferably provided on the frame 24 or 24', the provision of such weight is not always necessary, as long as the frame is sufficiently eccentrically weighted relative to the shaft 16 or 41. It will be understood that in the second embodiment B the motor 25' and batteries 27 which are disposed on the frame 24' in eccentric relation to the shaft 41 serve as effective eccentric weight means for the frame.
