The specific embodiment

Fig. 1 has shown an example of the toy top that the utility model is related, and this toy top A gives rotation by the starter that does not show among the figure, bends on the specular gameboard B of concave surface at recreation face b and rotates, and competes with other toy tops and plays.Toy top A constitutes (with reference to Fig. 2) by the lower part 3 of the middle level parts 2 of the height of the upper strata parts 1 of the function that possesses the toy top of attacking the opponent, decision toy top, the action form of decision toy top on gameboard B and with the screwed coupling components 4 that above-mentioned upper strata parts 1 and middle level parts 2 connect.

Upper strata parts 1 form in central authorities has the discoideus of the peristome 5 that inserts coupling components 4, at outer peripheral face, outside the attack portion 6 of the function that performance and opponent's toy top contact and attack extend out to and form.And, in the bottom surface, clip peristome 5 and a pair of chimeric teat 7 of symmetry projects to the below and forms (with reference to Fig. 3).By this chimeric teat 7 being embedded in the chimeric recess 11 of middle level described later parts 2, thereby easily with

upper strata parts

1 and 2 assemblings of middle level parts, and the circumferential play between two parts disappears.

Middle level parts 2 form tubular, have screw hole 9 at internal face, and screw hole 9 is formed with the ridge 8 that the screw 4a that makes coupling components 4 described later is threadedly engaged with.And, at the upper periphery face of middle level parts 2, be formed with the protrusion 10 of protuberance to the outside, at this protrusion 10, be formed with a pair of chimeric recess 11 (with reference to Fig. 2 and Fig. 4 A) symmetrically.

The lower end lateral surface of the tube portion 12 below extending to from this protrusion 10 is formed with a pair of engaging teat 14 (with reference to Fig. 2 and Fig. 4 B) that engages with the peristome 16 that is formed at lower part 3 described later.

Lower part 3 forms the rounding frustum by resin such as the plastics of the less raw-material hard of the frictional force coefficient of friction less, when contacting with recreation face b that produces when contact with the recreation face b of gameboard B or metal, below axial region 15 projects to and form.At the side face of this axial region 15, be provided with friction part 16.The coefficient of friction bigger rubber of this friction part 16 when contacting with recreation face b is raw material and forms cylindric (with reference to Fig. 6 A) that is provided with embedded hole 17 in central authorities, the internal diameter of embedded hole 17 forms the external diameter that is slightly less than above-mentioned axial region 15, by with this embedded hole 17 chimeric (interference fit) in axial region 15, thereby friction part 16 can be engaged (with reference to Fig. 6 B) with axial region 15.In addition, the thickness of above-mentioned friction part 16 forms the length that is shorter than above-mentioned axial region 15, and the front end 15a that sets axial region 15 when friction part 16 is fixed in axial region 15 for more projects to the below than friction part 16 and gets final product (with reference to Fig. 6 C).

Then, as shown in Figure 5, lower part 3 is center and be formed with a pair of circular-arc peristome 20 symmetrically in the upper outer of axial region 15 with axial region 15, and the part of the inwall of this peristome 20 forms engaging supporting part 21 to central elevation.By so constituting lower part 3, thereby make the part coupling that does not engage supporting part 21 of engaging teat 14 with the peristome 20 of lower part 3 of middle level parts 2, lower part 3 is embedded middle level parts 2 from the below, then, if make it along circumferentially rotating, so, the engaging teat 14 of middle level parts 2 is sticked in the downside of engaging supporting part 21, lower part 3 can be fixed on middle level parts 2.

When the toy top A of assembling said structure, at first, the chimeric teat 7 of upper strata parts 1 is embedded in the chimeric recess 11 (with reference to Fig. 7 A) of middle level parts.

Next, shown in Fig. 7 B, the screw 4a from the top with coupling components 4 inserts and pass through openings portion 5, is screwed into the screw hole 9 of middle level parts 2, and upper strata parts 1 are fixed on middle level parts 2.Under this state, parts 1 coupled parts 4 in upper strata are crimped on middle level parts 2, fix (with reference to Fig. 7 C) with being stabilized.

Then, shown in Fig. 7 C, make the engaging teat 14 of the tube portion 12 that is formed at middle level parts 2 insert the peristome 20 of lower part 3 accordingly, with respect to middle level parts 2 and along rotating in a circumferential direction lower part 3, make engaging teat 14 be sticked in the downside of engaging supporting part 21, thereby can form the toy top A (with reference to Fig. 7 D) that constitutes by upper strata parts 1, middle level parts 2, lower part 3.

If give rotation at a high speed to the toy top A that is formed by the starter that does not show among the figure, and be emitted on the inclined-plane of recreation face b of gameboard B (with reference to Fig. 8 A), so, at a high speed the toy top A of rotation since gyroscopic effect and with axial region 15 be central vertical erect, thereby the angle of the axial region 15 and the leading section of friction part 16 contacts with recreation face b, the function of friction part 16 performances that coefficient of friction is bigger when contacting with recreation face b as the rubber tyre, toy top A does not slide at recreation face b because of friction part 16, but hold reliably on recreation face b, depict circular arc, carry out high-speed mobile (revolution) simultaneously.At this moment, the rotary speed of toy top A is high more, moves with regard to depicting big more circular arc, shown in Fig. 9 A, toy top A can not rest on a place, but moves on recreation face b significantly, and action form is the attack mode that oneself moves and contacts with the other side's toy top.

If the rotary speed of toy top A descends, then Gong Zhuan radius reduces, shown in Fig. 9 B, toy top A moves to the central authorities of recreation face b, but shown in Fig. 8 B, near the central authorities or central authorities of recreation face b, friction part 16 is not contacted with recreation face b, the front end 15a that becomes the less axial region 15 of coefficient of friction when contacting with recreation face b is connected to the state of recreation face b, thereby toy top A becomes on the recreation face of the resting on b a bit, do not move and continue the persistent mode of rotation, wait for contacting with the other side's toy top.

As mentioned above, rotate at a high speed and be emitted on the inclined-plane of recreation face b of gameboard B if give to toy top A, then become friction part 16 and recreation face b state of contact, thereby friction part 16 does not dally on recreation face b and holds reliably, toy top A carries out revolution at a high speed and attacks the attack mode of opponent's toy top, if rotary speed descends, then Gong Zhuan diameter reduces, and just rotates in the central authorities of recreation face b soon.At this moment, because the front end 15a of the less axial region 15 of coefficient of friction is connected to recreation face b when contact with recreation face b, thereby in the persistent mode that continues rotation, the action form variation.

According to toy top A of the present utility model, can provide a kind of for the player and the producer all significant toy top, this toy top is for being provided with the simple structure of friction part 16 at axial region 15, first half in rotation at a high speed can be carried out the attack mode that contacts with the opponent energetically, negatively wait for the persistent mode of opponent's attack in the latter half of implementation of rotary speed decline, part is not recombinated and be not provided with and detect the mechanism of rotary speed, just can change action form with the complexity of change action form.

In addition, when toy top A is emitted to the recreation face b of gameboard B, not only can as described above toy top A be emitted on the inclined-plane of recreation face b, start pattern with attack mode, change to persistent mode then, and, can also be by toy top A being emitted to the central authorities of recreation face b, thereby make pattern from from the beginning of just being persistent mode, which thereby can determine to start with attack mode at first according to the position that toy top A is emitted to gameboard b, make pattern change to persistent mode then, perhaps from from the beginning of just starting with persistent mode, the strategy that can realize goes up the selection of the pattern of advantage.
