Abstract

A remote control toy has a main housing and a remote housing. A radio receiver is located in the main housing for receiving transmitted radio signals. The main housing includes a plurality of elements moveably mounted thereon which are set in motion by a motor in response to receipt of transmitted radio signals by the radio receiver. The remote housing incorporates a radio transmitter. The transmitter includes an electrical circuit having an antenna, a piezoelectric element for generating a current and an electrical component which is capable of generating a radio frequency signal in response to current flow through the electrical circuit. The remote housing further includes a moving member which is moved by the operator of the toy. The moving member is associated with the piezoelectric element to impact a mechanical force on the piezoelectric element for generation of an electrical current in the electrical circuit.

Claims

1. A remote control toy which comprises:

a main housing

a remote housing, said remote housing independent of said main housing;

receiver means mounted on said main housing, said receiver means for receiving a transmitted spark radio signal;

motion output means mounted on said main housing, said motion output means for producing a motion in response to receipt by said receiver means of said transmitted spark radio signal;

transmitter means mounted on said remote housing;

said transmitter means including an electrical circuit, said electrical circuit including a transmitting antenna, a piezoelectric element and spark gap means for producing a spark in said electrical circuit in response to an electrical current flow and for providing said spark radio signal responsive to said spark;

said remote housing further including

a moving means capable of being acted on by an operator of said toy and in response to said action said moving means moving against said piezoelectric element so as to cause said piezoelectric element to generate said electrical current flow in said electrical circuit.

2. The toy of claim 1 wherein:

said moving means includes a striking element moveably mounted in said remote housing in association with said piezoelectric element;

said moving means further including a biasing means associated with said striking element so as to bias said striking element toward said piezoelectric element.

3. The toy of claim 2 wherein:

said moving means further includes retaining means associated with said striking element, said retaining means for holding said striking element in a first position against the bias of said biasing means and releasing said striking elements so as said striking element is biased by said biasing means toward said piezoelectric element.

4. The toy of claim 1 wherein:

said moving means includes a striking element moveably mounted in said remote housing in association with said piezoelectric element;

said moving means further including a biasing means associated with said striking element so as to bias said striking element toward said piezoelectric element.

5. The toy of claim 4 wherein:

said moving means further includes retaining means associated with said striking element, said retaining means for holding said striking element in a first position against the bias of said biasing means and releasing said striking elements so as said striking element is biased by said biasing means toward said piezoelectric element.

6. The toy of claim 1 wherein:

said remote housing includes a first portion and a second portion, said second portion moveably mounted on said first portion;

said piezoelectric element mounted on said first portion;

said moving means operatively associated with said second portion, said moving means moving against said piezoelectric element in response to movement of said second portion with respect to said first portion.

7. The toy of claim 6 wherein:

said moving means includes a striking element moveably mounted in said remote housing in association with said piezoelectric element;

said moving means further including a biasing means associated with said striking element so as to bias said striking element toward said piezoelectric element;

said moving means further includes retaining means associated with said striking element, said retaining means for holding said striking element in a first position against the bias of said biasing means and releasing said striking elements so as said striking element is biased by said biasing means toward said piezoelectric element;

said biasing means comprising a spring associated with said second portion, said second portion moving with respect to said first portion compressing said spring, said spring associated with said striking element so as when said spring is compressed said spring is capable of biasing said striking element towards piezoelectric element.

8. The toy of claim 1 wherein:

said motion output means includes a motor means and a power means, said power means for supplying power to said motor means;

said receiver means includes a receiver circuit, said receiver circuit electrically connected to said motor means so as to control said motor means.
