Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
95 words
In a toy of the type including a bowl having a planetsimulating region at its center and a ball for rolling circularly around the inside of the bowl to simulate a spacecraft orbiting the planet, the improvement wherein: the bowl comprises a circular base defining the central planetsimulating region and sidewalls extending outward and convexly upward from the base, whereby the centripetal reaction force exerted by the sidewalls upon the circularly rolling ball diminishes with increasing radius of the circular path to simulate the relation between gravitational force and orbital radius of an actual spacecraft.
Claim 2
Dependent Claim
95 words

Claim 5
Dependent Claim
75 words

Claim 9
Dependent Claim
62 words
The toy of claim 4 wherein the movable barrier comprises: an upstanding cylindrical portion adapted for slidably fitting within the opening of the inward extending portion of the rim whereby the rolling ball is prevented from entering the circumferentiaL channel and thence escaping through the tangential passageway when the cylindrical portion of the barrier is positioned within the opening of the rim.
Claim 10
Dependent Claim
56 words
The toy of claim 7 wherein the movable barrier comprises: a spider having a central hub and radial members extending therefrom to connect the hub to the cylindrical portion of the barrier, whereby the barrier can be selectively positioned in the way of or clear of the circumferential channel by respectively lowering or raising the hub.
Claim 11
Dependent Claim
23 words
The toy of claim 4 comprising a launching device for propelling the ball into an orbital path around the inside of the bowl.
Claim 12
Dependent Claim
117 words
The toy of claim 9 wherein the launching device comprises: a launching arm pivotally mounted for rotation about one end, the axis of rotation coinciding with the central axis of the bowl; biasing means for urging the launching arm in one rotational direction; latching means for releasably holding the launching arm from rotation by the biasing means; and finger-operated means for releasing the latching means after the ball has been placed in the path of rotation of the launching arm at the bottom of the bowl, whereby the released launching arm will rotate under the influence of the biasing means and strike the ball to propel it into an orbital path around the inside of the bowl.
Claim 13
Dependent Claim
54 words
The toy of claim 10 wherein: the finger-operated releasing means comprises a pivotally mounted lever spring biased toward a position adjacent the plane of rotation of the arm, and the latching means comprises a stop extending laterally from the lever in the way of the launching arm when the lever is in said position.
Claim 14
Dependent Claim
25 words
The toy of claim 11 wherein the launching device comprises: means for selectively varying the launch velocity imparted to the ball by the launching arm.
Claim 15
Dependent Claim
35 words
The toy of claim 12 wherein the launch velocity varying means comprises: a series of depressions in the bottom of the launching device positioning the ball along the path of rotation of the launching arm.
Claim 16
Dependent Claim
87 words
The toy of claim 4 comprising means for injecting the ball into an orbital path around the inside of the bowl, said inject means including: a tube having an inside diameter larger than the diameter of the ball, one end of said tube being clamped to said barrier in position for injecting the ball into an orbital path inside the bowl, and a releasable spring-loaded plunger inserted in the other end of the tube for impelling the ball through the tube for injection into said orbital path.
Claim 17
Dependent Claim
24 words
The toy of claim 7 wherein the movable barrier further comprises an annular lip extending inward from the lower edge of the cylindrical portion.
Claim 18
Dependent Claim
