## Abstract

A toy top includes a shaft portion, a body and an attacking member. The body is rotatable relative to the shaft portion in response to an impact applied to the body. The attacking member is movably connected to the body to move in a predetermined direction relative to the body between first and second positions. 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 3)

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.

### Claim 5 (depends on 3)

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.

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 3)

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.

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 7)

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.

### Claim 10 (depends on 9)

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.

### Claim 11 (depends on 7)

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.

### Claim 12 (depends on 1)

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.

### Claim 13 (depends on 1)

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.

### Claim 14 (depends on 13)

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

### Claim 15 (depends on 1)

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.

### Claim 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.

### Claim 17 (depends on 16)

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.

### Claim 18 (depends on 17)

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

### Claim 19 (depends on 17)

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.

### Claim 20 (depends on 16)

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.

### Claim 21 (depends on 16)

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.

### Claim 22 (depends on 21)

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.

### Claim 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,
