Abstract

An anti-theft vehicle system for a vehicle wheel having a rotational axis includes at least one inhibitor disposed within the vehicle wheel to selectively engage and disengage the vehicle wheel to resist and allow rotational movement of the vehicle wheel about its rotational axis. The anti-theft vehicle system also includes rotatable structure disposed within the vehicle wheel and cooperating with the at least one inhibitor for moving the at least one inhibitor between an engaged position and a disengaged position with respect to the vehicle wheel. The anti-theft vehicle system further includes a receiver operatively associated with the vehicle wheel to receive a predetermined signal to activate the rotatable structure to move the at least one inhibitor between the engaged position and disengaged position.

Claims

1. An anti-theft vehicle system for a vehicle comprising:

at least one vehicle wheel;

at least one inhibitor operatively associated with the at least one vehicle wheel to engage and disengage the at least one vehicle wheel to resist and allow rotational movement of the at least one vehicle wheel; and

a receiving circuit operatively associated with the at least one vehicle wheel to receive a predetermined signal having a frequency of less than nine kilohertz to activate and move said at least one inhibitor between an engaged position and a disengaged position with respect to said at least one vehicle wheel.

2. An anti-theft vehicle system as set forth in claim 1 including a structure operatively associated with said at least one vehicle wheel and cooperating with said at least one inhibitor for moving said at least one inhibitor between said engaged position and said disengaged position.

3. An anti-theft vehicle system as set forth in claim 2 wherein said structure is rotatable.

4. An anti-theft vehicle system as set forth in claim 1 including a transmitting circuit for transmitting the predetermined signal.

5. An anti-theft vehicle system for a vehicle comprising:

at least one vehicle wheel;

a structure operatively associated with said at least one vehicle wheel for moving between an engaged position and a disengaged position with respect to said at least one vehicle wheel to resist and allow rotational movement of said at least one vehicle wheel; and

a receiving circuit operatively associated with said at least one vehicle wheel to receive a predetermined signal having a frequency of less than nine kilohertz to activate and move said structure between said engaged position and said disengaged position.

6. An anti-theft vehicle system as set forth in claim 5 wherein said structure is rotatable.

7. An anti-theft vehicle system as set forth in claim 5 including a transmitting circuit for transmitting the predetermined signal.

8. An anti-theft vehicle system for a vehicle comprising:

at least one vehicle wheel;

at least one inhibitor operatively associated with said at least one vehicle wheel to engage and disengage said at least one vehicle wheel to resist and allow rotational movement of said at least one vehicle wheel;

a structure operatively associated with said at least one vehicle wheel and cooperating with said at least one inhibitor for moving said at least one inhibitor between an engaged position and a disengaged position with respect to said at least one vehicle wheel;

a receiving circuit operatively associated with said at least one vehicle wheel to receive a predetermined signal to activate said structure to move said at least one inhibitor between said engaged position and said disengaged position; and

a transmitting circuit for transmitting the predetermined signal having a frequency of less than nine kilohertz.

9. An anti-theft vehicle system as set forth in claim 8 wherein said structure is rotatable.

10. An anti-theft vehicle system for a vehicle comprising:

at least one vehicle wheel;

at least one inhibitor operatively associated with said at least one vehicle wheel to engage and disengage said at least one vehicle wheel to resist and allow rotational movement of said at least one vehicle wheel;

a rotatable structure operatively associated with said at least one vehicle wheel and cooperating with said at least one inhibitor for moving said at least one inhibitor between an engaged position and a disengaged position with respect to said at least one vehicle wheel; and

a receiving circuit disposed within said at least one vehicle wheel to receive a predetermined signal having a frequency of less than nine kilohertz to activate said rotatable structure to move said at least one inhibitor between said engaged position and said disengaged position.

11. An anti-theft system for a shopping cart comprising:

at least one inhibitor operatively associated with the shopping cart to resist and allow movement of the shopping cart; and

a receiver operatively associated with the shopping cart to receive a predetermined square wave signal having a frequency of less than nine kilohertz to activate said at least one inhibitor to resist movement of the shopping cart.

12. An anti-theft system for a shopping cart comprising:

a structure operatively associated with a shopping cart to inhibit movement of the shopping cart; and

a receiver operatively associated with the shopping cart and connected to said structure to receive a predetermined square wave signal having a frequency of less than nine kilohertz to activate said structure.
