Toy top

1. A toy top comprising:

a shaft portion;

a body which is rotatable relative to the shaft portion in response to an impact applied to the body; and

an attacking member movably connected to the body to move in a predetermined direction relative to the body between first and second positions,

wherein in the second position the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion.

2. The toy top according to claim 1 , wherein the predetermined direction is a radial direction relative to the body.

3. The toy top according to claim 1 , further comprising:

a limiter which engages the attacking member and limits the protruding distance of the attacking member according to the rotating position of the body relative to the shaft portion.

4. The toy top according to claim 3 , wherein the limiter defines an area in which the attacking member can move to vary the protruding distance of the attacking member.

5. The toy top according to claim 3 , wherein the limiter includes a cam extending between the body and the attacking member to vary the protruding distance of the attacking member.

6. The toy top according to claim 5 , wherein the cam is selected from a grooved cam, a disk cam or a positive cam.

7. The toy top according to claim 3 ,

wherein the body rotates together with the attacking member,

wherein the body further comprises a part which engages with the shaft portion and rotates together with the shaft portion, and

wherein the limiter is disposed on the part.

8. The toy top according to claim 7 , wherein the part engages with the shaft portion via a flywheel.

9. The toy top according to claim 7 , wherein the limiter is a continuous depression formed in the part and the depression has a first end that is smaller than a second, opposite end of the depression.

10. The toy top according to claim 9 , wherein the attacking member includes a projection, the attacking member is in the second position when the projection is in the second end, and the attacking member is in the first position when the projection is in the first end.

11. The toy top according to claim 7 , wherein the body is two spaced plates between which the part, which is also a plate, is received.

12. The toy top according to claim 1 ,

wherein the body has one of projections and recesses, and the shaft portion has the other of the projections and recesses, and

wherein the projections and recesses cooperate when the body rotates relative to the shaft portion to provide a variable rotational rate in response to a collision with an opponent toy top.

13. The toy top according to claim 1 ,

wherein the toy top is movable between a coupled state and a decoupled state,

wherein the shaft portion and the body are in the coupled state when the shaft portion is positioned on the body and the body is rotated in a first direction relative to the shaft portion, and

wherein the shaft portion and the body are in the decoupled state when the body is rotated in a second direction relative to the shaft portion.

14. The toy top according to claim 13 , wherein the first position is fully retracted in the body.

15. The toy top according to claim 1 ,

wherein the body has a circumference,

wherein the attacking member is a plurality of attacking members attached to the circumference, and

wherein each of the attacking members moves radially relative to the body between the first and second positions.

16. A toy top comprising:

a shaft portion;

a body which is removably connected to the shaft portion and is rotatable relative to the shaft portion in response to an impact applied to the body;

an attacking member movably connected to the body to move radially relative to the body between first and second positions; and

a limiter which engages the attacking member,

wherein in the second position the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion, and

wherein the limiter limits the protruding distance of the attacking member according to the rotating position of the body relative to the shaft portion.

17. The toy top according to claim 16 ,

wherein the body rotates together with the attacking member,

wherein the body further comprises a part which engages with the shaft portion and rotates together with the shaft portion, and

wherein the limiter is disposed on the part.

18. The toy top according to claim 17 , wherein the part engages with the shaft portion via a flywheel.

19. The toy top according to claim 17 , wherein the body is two spaced plates between which the part, which is also a plate, is received.

20. The toy top according to claim 16 ,

wherein the body has a circumference, and

wherein the attacking member is a plurality of attacking members attached to the circumference.

21. The toy top according to claim 16 , wherein the limiter is a continuous depression formed in the part and the depression has a first end that is smaller than a second, opposite end of the depression.

22. The toy top according to claim 21 , wherein the attacking member includes a projection, the attacking member is in the second position when the projection is in the second end, and the attacking member is in the first position when the projection is in the first end.

23. A toy top comprising:

a shaft portion;

a body which is removably connected to the shaft portion and is rotatable relative to the shaft portion in response to an impact applied to the body;

an attacking member movably connected to the body to move radially relative to the body between first and second positions; and

a limiter which engages the attacking member;

wherein in the second position the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion; and

wherein the limiter limits the protruding distance of the attacking member according to the rotating position of the body relative to the shaft portion,

wherein the body rotates together with the attacking member,

wherein the body further comprises a part which engages with the shaft portion and rotates together with the shaft portion,

wherein the limiter is disposed on the part and is a continuous depression formed in the part, and

wherein the depression has a first end that is smaller than a second, opposite end of the depression.
