Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
216 words
An inertia toy apparatus, comprising: means defining a supporting housing said housing having a pair of spaced apart supporting upright members; a wheel supporting spindle rotatably mounted generally transversely between said upright members thereby providing an axis arranged for horizontal disposition relative a tracking surface, said spindle being rotably mounted in said housing and having a driving surface thereon for rotating the spindle; a wheel releasably mounted on said spindle; a driven train in said housing and connected with said wheel supporting spindle for driving the same; a driving member cooperating with the drive train for imparting movement to the drive train to rotate said spindle; locking means releasably securing the wheel against axial dislodgement from the spindle including a locking surface on said wheel and a locking member cooperating with said wheel supporting spindle for cooperating with said wheel locking surface to releasably secure the wheel on said spindle, said locking means being releasable responsive to the termination of driving forces from said driving member to release the mutual engagement of the components thereof and permit release of the wheel from the spindle responsive to the stored momentum resultant from rotation of said spindle whereby said wheel may move axially off the generally horizontally disposed spindle and drop to a tracking surface and roll therealong.

Claim 3
Dependent Claim
30 words
The toy of claim 1 wherein the driven train and driving member comprises a gear train and a manually movable arm having gear teeth in engagement with the gear train.
Claim 4
Dependent Claim
27 words
The toy of claim 2 wherein one gear of the train is movable out of engagement with other gears responsive to termination of driving by the arm.
Claim 5
Dependent Claim
21 words
The toy of claim 1 wherein the locking means includes surfaces generally radially arranged relative to the axis of said spindle.
Claim 6
Dependent Claim
23 words
The toy of claim 4 wherein the locking surfaces include a threaded bore of the wheel and complementary exterior thread on the spindle.
