Description

  This invention relates to a top toy that can change its rotational behavior.

Some top toys that can be rotated on an amusement stand or the like can change their behavior during rotation by exchanging constituent parts such as a ground shaft and a body part.
In such a top toy, since the number of component parts to be prepared increases, in recent years, it has been devised that the rotational behavior can be changed without exchanging the component parts (see, for example, Patent Document 1).

  The top toy described in Patent Document 1 is provided with a mechanism that allows the protruding position of the ground shaft to be moved in the radial direction on the lower surface of the body part, and by appropriately adjusting the protruding position of the ground shaft by the mechanism, the top toy The rotation behavior (spinning behavior) can be changed.

Utility Model Registration No. 3154824

However, in the above conventional top toy, the rotation behavior is changed by changing the protruding position of the grounding shaft, so the change in behavior can be easily predicted just from the outside. If you play with a collision, your opponent will read the strategy.
Furthermore, in the above conventional top toy, the center of the ground shaft (that is, the ground contact position with the play surface) is shifted from the center of rotation to change the protruding position of the shaft, and when the top toy is rotated, On the other hand, the ground contact position revolves. For this reason, there has been a drawback that the rotation has poor durability while exhibiting a new dynamic behavior such as a bouncing behavior.

  Therefore, the present invention is intended to provide a top toy that can change the rotation behavior without easily distinguishing the appearance from the appearance or deteriorating the rotation durability of the top toy. .

The top toy according to the present invention employs the following means in order to solve the above problems.
According to a first aspect of the present invention, the body portion coupled to the ground shaft includes a first body component and a second body component coupled in a layered manner in the axial direction, the first body component and the first body component. The center of gravity of each of the two fuselage parts is installed at a position decentered with respect to the rotation center, and the first fuselage part and the second fuselage part are assembled so that the relative position of the mutual center of gravity can be changed. It is characterized by.
Thereby, for example, when the first fuselage part and the second fuselage part are assembled so that their center of gravity overlaps in the circumferential direction, the first fuselage part and the second fuselage part are combined. The weight of the entire eccentric part becomes heavy, and the top toy has a rotational behavior that is largely swung by the eccentric part. Further, for example, when the first body part and the second body part are assembled so that the positions of their center of gravity are 180 ° apart from each other in the circumferential direction, the eccentric part of the first body part and The eccentric part of the second body part is balanced, and the top toy has a stable rotational behavior.

The invention according to claim 2 is the top toy according to claim 1, wherein one of the opposing surfaces of the first body part and the second body part is provided with a convex portion at a position spaced from the rotation center, On the other of the opposing surfaces of the first body part and the second body part, concave portions that can be fitted to the convex portions are provided at a plurality of positions on concentric circles spaced from the rotation center, and fitted to the convex portions. The depth of one possible concave portion and the other concave portion that can be fitted to the convex portion are set differently.
As a result, on the side of the first fuselage part and the second fuselage part on which the convex portion is provided, the weight of the portion where the convex portion exists partially increases, and the first fuselage component and the second fuselage component Of the body parts, the side where the concave portion is provided is heavier in the portion where the shallow concave portion is provided than the portion where the deep concave portion is provided. For this reason, the rotation balance is changed by changing the fitting position of the convex part and the concave part of the first body part and the second body part. Moreover, the relative rotation of the first body part and the second body part is regulated by fitting the convex part and the concave part.

  According to the first aspect of the present invention, the center of gravity of the first body part and the second body part stacked in layers in the axial direction is eccentric, and both body parts are assembled so that the relative position of each center of gravity can be changed. Therefore, by appropriately changing the relative positions of the center of gravity of both body parts, the rotational behavior can be changed without being easily distinguished from the outside. Furthermore, in this device, since the position of the grounding shaft is not changed, the rotation center and the grounding point always coincide with each other, and even when the top toy is swung around, the rotation durability can be improved. There is no deterioration.

  According to the second aspect of the invention, the rotational behavior can be changed by changing the fitting position of the convex portion and the concave portion provided on the opposing surfaces of the first body part and the second body part. The relative rotation of the first body part and the second body part can also be restricted by the fitting of the convex part and the concave part. In addition, since the eccentric parts of the first body part and the second body part are provided in the fitting portions between them, there is also an advantage that the state of the change is less visible from the outside.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 and 2 are diagrams showing an overall configuration of the top toy 1 according to this embodiment.
As shown in these drawings, the top toy 1 is composed of a grounding shaft 10 that comes into contact with a grounding surface of a play table or the like at the tip during rotation, and a body portion 11 coupled to the grounding shaft 10. . The body portion 11 includes an upper layer member 12 that collides with and attacks the top piece toy that fights, and a middle layer member 13 that is interposed between the ground shaft 10 that is the lower layer member and the upper layer member 12 and determines the height of the top piece 1. It has.

  The upper layer member 12 is superposed on the upper surfaces of the first and second side attack components 14 and 15 that collide with and attack the side surfaces of the top toy to fight, and the top surfaces of the first side attack components 14 and the bottom surface of the top toy that fights. And a lower surface attack component 16 that attacks and collides with. The first and second side surface attack parts 14 and 15 are each formed of a metal material, and constitute a first body part and a second body part in the present invention. On the other hand, the lower surface attack component 16 is formed of a resin material, and a plurality of attacking uneven portions are provided on the upper surface side.

  The first side attack component 14 and the second side attack component 15 are both formed in a substantially disc shape, and the first side attack component 14 is located on the upper side with respect to the second side attack component 15. Thus, they are stacked in layers in the axial direction and are connected to each other in that state.

  As shown in FIG. 2, the second side surface attack component 15 includes a thick annular outer peripheral ring portion 17, and extends radially inward from the lower end side inner peripheral portion of the outer peripheral ring portion 17. A bottom wall plate portion 19 having a fitting hole 18 having a shape, and a bridge portion 20 extending to the inner peripheral portion on the upper end side of the ring portion 17 so as to cross the outer peripheral ring portion 17 in the diameter direction. A seat ring 21 having a circular opening 21 a is provided at the center of the bridge portion 20.

Four recesses 22 are provided on the outer edge on the upper surface side of the outer peripheral ring portion 17 at equal intervals in the circumferential direction. The four recesses 22 are all formed in an arc shape having the same width and length in plan view, but the depth of one of them is shallower than the depth of the remaining one. Hereinafter, when distinguishing the recesses 22 having different depths, the shallow recesses 22 are referred to as shallow recesses 22A, and the deep recesses 22 are referred to as deep recesses 22B.
The bottom wall in the shallow concave portion 22A of the outer peripheral ring portion 17 is thicker than the bottom wall in the deep concave portion 22B, and the region where the shallow concave portion 22A exists on the circumference of the outer peripheral ring portion 17 is the region where the deep concave portion 22B exists. The weight is heavier than. Therefore, the position of the center of gravity of the second side attack component 15 is biased toward the region where the shallow recess 22A exists.

On the other hand, as shown in FIG. 2, the first side surface attack component 14 is formed in a ring shape having the same width as the outer peripheral ring portion 17 of the second side surface attack component 15, and its lower surface side (second side surface). One convex portion 23 is provided on a part of the side facing the attack component 15. The convex portion 23 is formed in an arc shape having substantially the same width and length as the concave portion 22 in plan view, and can be fitted to any of the concave portions 22 (the shallow concave portion 22A and the deep concave portion 22B). And the protrusion height of the convex part 23 is set to be substantially the same as the depth of the shallow concave part 22A, and when the convex part 23 is fitted into any of the concave parts 22A and 22B, the first side attack component 14 and the second The height of the overlapping portion of the second side attack component 15 is not changed.
On the circumference of the first side surface attack component 14, the region where the convex portion 23 exists is partially heavier than the remaining region. Therefore, the position of the center of gravity of the first side attack component 15 is biased toward the region where the convex portion 23 exists.

  Further, the lower surface attack component 16 superposed on the upper surface of the first side surface attack component 14 is formed with a through hole 24 in the central portion and fitted with the bridge portion 20 of the second side surface attack component 15 on the lower surface side. A mating engagement wall 25 is provided.

  The middle layer member 13 is formed in a substantially cylindrical shape as shown in FIG. 2, and the ground shaft 10 is locked and fixed to the lower end thereof. Further, a substantially hexagonal fitting wall 26 is formed on the upper edge side of the middle layer member 13, and the fitting wall is fitted with the fitting hole 18 of the second side attack component 15. . A screw hole 27 is formed in the upper end surface of the middle layer member 13, and a screw member 28 for fastening and fixing the upper layer member 12 and the middle layer member 13 is screwed into the screw hole 27.

  When the upper layer member 12 and the middle layer member 13 are assembled, the second side attack component 15 is superposed in a state where the three components of the lower surface attack component 16, the first side attack component 14, and the second side attack component 15 are superposed. The fitting wall 26 of the middle layer member 13 is fitted into the fitting hole 18 from the lower side, and in this state, the screw member 28 is inserted from the upper side of the lower surface attack component 16, and the screw member 28 is inserted into the middle layer member 13. By tightening in the screw hole 27, the three components 16, 14, 15 of the upper layer member 12 are fixed integrally to the middle layer member 13 in a state where they are pressed against each other.

Next, a case where the rotation characteristic of the top toy 1 is changed will be described.
FIG. 3 is a diagram for explaining a case where the rotation characteristic of the top toy 1 is set to the attack type (unbalanced rotation type), and FIG. 4 is a diagram illustrating the rotation characteristic of the top toy 1 set to the stable type (balance rotation type). It is a figure explaining the case to do.
When the top toy 1 is set to the attack type shown in FIG. 3, the first side surface attack component 14 and the second side surface attack component 15 are fitted so that the convex portion 23 is fitted in the shallow concave portion 22A. In the assembled state, the upper layer member 12 that is layered as described above is integrally fixed to the middle layer member 13 by the screw member 28. Thus, when the convex portion 22 of the first side attack component 14 is fitted into the shallow recess 22A of the second side attack component 15, the first side attack component 14 and the second side attack component 15 are combined. As a result, the weight of the entire eccentric portion is increased, and as a result, the top toy 1 has a rotational behavior that is largely swung by the eccentric portion.

  On the other hand, when the top toy 1 is set to the stable type shown in FIG. 4, the first side attack component 14 and the second side attack component 15 are connected to the shallow recess 22A and the deep recess 22B in an axially symmetric position. In this state, the upper layer member 12 stacked in layers is fixed to the middle layer member 13 by a screw member 28. Thus, when the convex portion 22 of the first side surface attack component 14 is fitted into the deep concave portion 22B symmetrical to the shallow concave portion 22A of the second side surface attack component 15, the eccentric portion of the first side surface attack component 14 And the eccentric part of the second side attack component 15 are balanced with respect to the rotation center, and as a result, the top toy 1 has a stable rotational behavior.

  Further, when the rotational behavior of the top toy 1 is changed to an intermediate behavior between the stable type and the attack type described above, the convex portion 23 of the first side attack component 14 is shallower than the second side attack component 15. What is necessary is just to assemble | attach the 1st side surface attack component 14 and the 2nd side surface attack component so that it may fit in the deep recessed part 22B adjacent to the recessed part 22A.

As described above, in the top toy 1, the first side attack component 14 and the second side attack component 15 that are stacked in layers in the axial direction are provided with eccentric portions, and each center of gravity shifted by the eccentric portion is provided. Since the 1st side surface attack component 14 and the 2nd side surface attack component 15 are assembled | attached so that a relative position can be changed, a rotation behavior can be changed in the site | part which is hardly conspicuous from the outer side. Therefore, when this top toy 1 is used, a change in rotational behavior is not easily determined by the opponent.
Furthermore, in this top toy 1, the position of the grounding shaft is not changed at all and always coincides with the center of rotation. Therefore, even if the top toy 1 takes a rotating behavior, the rotational durability is maintained. There is no deterioration.

Moreover, in this top toy 1, the fitting position of the convex part 23 and the recessed part 22 (22A, 22B) provided in the opposing surface of the 1st side surface attack component 14 and the 2nd side surface attack component 15 is changed. Thus, since the rotation behavior is changed, the first side attack component 14 and the second side attack component 15 can be prevented from being displaced in the rotation direction by fitting the convex portion 23 and the concave portion 22. it can.
In addition, in the case of the top toy 1, the eccentric portion is provided by the convex portion 23 and the concave portion 22 provided on the opposing surfaces of the first side attack component 14 and the second side attack component 15. There is an advantage that the change in the external shape accompanying the change in behavior is less visible from the outside.

  The invention is not limited to the above-described embodiment, and various design changes can be made without departing from the gist thereof. For example, in the above embodiment, the first body part (first side attack part 14) and the second body part (second side attack part 15) are each provided with a fitting part by a convex part and a concave part. The eccentric parts are formed in these fitting parts, but a partial cavity is provided inside the first body part and the second body part or another member having a different specific gravity is embedded. An eccentric portion may be formed by the above.
