Abstract

A toy horse (100, 200) is disclosed as including a body (102, 202) for carrying a user, four legs (104a, 104b, 104c, 104d, 204a, 204b, 204c, 204d) mounted for movement relative to the body (102, 202), and motors (106a, 106b, 206) operatively associated with a number of gears (108a, 108b, 108c, 108d, 208a, 208b, 208c, 208d) each associated with a respective leg (104a, 104b, 104c, 104d, 204a, 204b, 204c, 204d) which is movable by the respective gears (108a, 108b, 108c, 108d, 208a, 208b, 208c, 208d) to exhibit walking movement. Each leg (204a, 204b, 204c, 204d) is provided with a respective wheel (230a, 230b, 230c, 230d), drivenable by a respective motor (232a, 232b, 232c, 2332d), and the motors (232a, 232b) driving the wheels (230a, 230b) of the right legs (204a, 204b) are operable independently from the motors (232c, 232d) driving wheels (230c, 230d) of the left legs (204c, 204d).

Claims

1. An electric toy including:

a body member adapted to carry a user;

a plurality of limb members mounted on said body member for movement relative to said body member; and

at least a first motor operatively associated with a plurality of gear members each associated with a respective limb member;

wherein said limb members are movable by said gear members to exhibit walking movement.

2. A toy according to claim 1 wherein each said limb member is rotatably movable relative to a respective gear member about an axis different from an axis of rotation of said gear member.

3. A toy according to claim 1 further including a pair of right limb members, wherein the gear members of said right limb members are connected by a chain member.

4. A toy according to claim 3 wherein said pair of right limb members are drivenable by said first motor.

5. A toy according to claim 1 further including a pair of left limb members, wherein the gear members of said left limb members are connected by a chain member.

6. A toy according to claim 5 wherein said pair of left limb members are drivenable by a second motor.

7. A toy according to claim 1 further including two front limb members which are rotatable relative to said body member out-of-phase by 180°

.

8. A toy according to claim 1 further including two rear limb members which are rotatable relative to said body member out-of-phase by 180°

.

9. A toy according to claim 1 further including a programmable logic controller for controlling the operation of said toy.

10. A toy according to claim 1 further including at least a mass movable relative to said body member during movement of said limb members.

11. A toy according to claim 10 further characterized in that said mass comprises at least a battery for powering said toy.

12. A toy according to claim 10 further characterized in that said mass is movable substantially parallel to a longitudinal axis of said body member.

13. A toy according to claim 10 further characterized in that said mass is reciprocable along a straight line substantially parallel to a longitudinal axis of said body member.

14. A toy according to claim 10 further characterized in that said mass is positioned on a movable member operatively associated with said first motor.

15. An electric toy including:

a body member adapted to carry a user;

said body member carrying at least a right limb member and a left limb member;

each said limb member carrying a respective wheel member;

a first motor operable to drive said wheel member of said right limb member; and

a second motor operable to drive said wheel member of said left limb member;

wherein said first and second motors are operable independently.

16. A toy according to claim 15 wherein said wheel members are each rotatable about a respective axis substantially transverse to a longitudinal axis of said body member.

17. A toy according to claim 15 wherein said first and second motors are operable to drive said wheel member of said right limb member and said wheel member of said left limb member to rotate in opposite directions.

18. A toy according to claim 15 wherein said toy includes two right limb members and two left limb members, each carrying a respective wheel member.

19. A toy according to claim 18 wherein said first motor is operable to drive said wheel members of said right limb members to rotate in the same direction.

20. A toy according to claim 18 wherein said second motor is operable to drive said wheel members of said left limb members to rotate in the same direction.

21. A toy according to claim 15 further including a programmable logic controller for controlling the operation of said toy.

22. A toy according to claim 15 further including at least a mass movable relative to said body member during movement of said limb members.

23. A toy according to claim 22 further characterized in that said mass comprises at least a battery for powering said toy.

24. A toy according to claim 22 further characterized in that said mass is movable substantially parallel to a longitudinal axis of said body member.

25. A toy according to claim 22 further characterized in that said mass is reciprocable along a straight line substantially parallel to a longitudinal axis of said body member.

26. A toy according to claim 22 further characterized in that said mass is positioned on a movable member operatively associated with said first motor.
