Abstract

A moveable toy which includes a motor for producing motion. Associated with the motor is a motor controller for accelerating and deaccelerating the motor. A rotary element is driven by the motor. Associated with the rotary element is a flywheel which is capable of being rotated by the rotary element, but is also capable of independent rotation. The flywheel is further associated with a switch which governs the output of the motor to several moving elements located on the toy. The flywheel interacts with the switch to shift the output to the individual moving elements each time the speed of the flywheel differs from that of the rotating element. The motor controller deaccelerates the motor which in turn deaccelerates the rotating element upon command of the operator of the toy.

Claims

1. A toy which comprises:

a housing;

a motor mounted on said housing, said motor producing a rotational output in a constant direction to move portions of said toy;

motor control means mounted on said housing in operative association with said motor, said motor control means being for controlling said motor by accelerating and decelerating said motor;

a flywheel rotatably mounted on said housing;

motion transfer means located on said housing in operative association with said flywheel and said motor for transferring rotation of said motor to said flywheel whereby said flywheel can be rotated by said motor;

switch means mounted on said housing in operative association with said flywheel said switch means including a switching member mounted to said housing for movement from at least a first position to a second position with respect to said housing, means including said flywheel for moving said switching member from one to the other of said positions and back again, respectively, in response to acceleration and deceleration of said motion transfer means with respect to said flywheel;

output means mounted on said housing in operative association with said motor whereby said motor drives said output means, said output means being capable of outputting a selected one of at least two independent outputs, said output means further operatively associated with said switch means whereby said output means outputs one of its outputs in response to said switching member being in one of said positions and said output means outputs a further of its outputs in response to said switching member being in the other position;

said switch means including at least one switch gear operatively associated with said motor so as to be rotated by said motor;

said switch means further including a positioning member rotatably mounted on said housing for changing the position of said switch gear relative to said motor, said switch gear being eccentrically mounted on said positioning member so as to rotate in association with said positioning member whereby it can move from a position effecting its use in one of said outputs to another position effecting its use in another of said outputs.

2. The toy of claim 1 wherein:

said switching member being moveably mounted on said housing in operative association with both said flywheel and said positioning means, said flywheel moving said switching member on said housing, said switching member, in moving on said housing, interacting with said positioning member so as to position said positioning member in a plurality of positions on said housing and said positioning means, in turn, positioning said switch gear in a like number of positions on said housing.

3. The toy of claim 2 wherein:

said positioning member includes a plurality of positioning elements located on said positioning member, at least two of said positioning elements located axially with respect to each other on said positioning member, and at least two of said positioning elements located circumferentially with respect to each other on said positioning member.

4. The toy of claim 2 wherein:

said output means including gear train means for transferring rotational motion, said gear train means having at least two output gears, each of said output gears independently opertively associated with said motor and rotated by said motor in response to said switching member being in one of said respective positions;

said switch gear meshing with at least one of said output gears in each of said positions of said switch gear, said switch gear transferring rotation to any of said output gears in mesh with said switch gear to rotate said respective output gear.

5. A toy which comprises:

a housing;

a motor mounted on said housing, said motor producing a rotational output in a constant direction to move portions of said toy;

motor control means mounted on said housing in operative association with said motor, said motor control means being for controlling said motor by accelerating and decelerating said motor;

a flywheel rotatably mounted on said housing;

motion transfer means located on said housing in operative association with said flywheel and said motor for transferring rotation of said motor to said flywheel whereby said flywheel can be rotated by said motor;

switch means mounted on said housing in operative association with said flywheel, said switch means including a switching member mounted to said housing for movement from at least a first position to a second position with respect to said housing, means including said flywheel for moving said switching member from one to the other of said positions and back again, respectively, in response to acceleration and deceleration of said motion transfer means with respect to said flywheel;

output means mounted on said housing in operative association with said motor whereby said motor drives said output means, said output means being capable of outputting a selected one of at least two independent outputs, said output means further operatively associated with said switch means whereby said output means outputs one of its outputs in response to said switching member being in one of said positions and said output means outputs a further of its outputs in response to said switching member being in the other position;

said motion transfer means including a rotating element, said rotating element being rotatably mounted on said housing in association with said flywheel, said rotating element being operatively connected to said motor so as to be rotated by said motor;

said motion transfer means further including a connecting means for operatively connecting said flywheel to said rotating element for rotating said flywheel;

a shaft, said shaft mounted on said housing;

said rotating element and said flywheel being mounted on said shaft and independently rotatable with respect to each other;

said connecting means including a helical surface fixed to said rotating element and helically extending along the axis of rotation of said shaft towards said flywheel, said connecting means further including an engagement member axially extending from said flywheel towards said helical surface so as to contact said helical surface;

said flywheel axially moving along said shaft in response to movement of said engagement member on said helical surface.
