The present invention relates to a top toy.
Known from the past are top toys with a fitting hole, in which a rotating shaft can be freely inserted and removed, is formed in the bottom center of the toy body, configured so that both ends of the rotating shaft can be switched and fitted into the fitting hole (see Patent Document 1).
According to this top toy, one end of the rotating shaft is formed in a flat plane shape, and the other in a cone shape, making it possible to change the rotation characteristics of the top toy before and after switching the rotating shaft.
In this top toy, to prevent the rotating shaft from coming out, the rotating shaft is constituted using a metal which is a magnetic body, and a magnet that attracts the rotating shaft by magnetic force is installed inside the toy body.
However, because the shaft end of the rotating shaft is thin, particularly to effectively attract the cone shaped shaft end, an expensive magnet having a considerable attractive force is necessary, and it is necessary to constitute the rotating shaft using a magnetic body.
The invention of the present application was created considering these circumstances, and its purpose is to provide a top toy in which it is possible to easily exchange the shaft without using a magnet, and the rotation characteristics can be changed.
A top toy includes a trunk part, first and second shafts, and a locking part. The trunk part has an insertion hole. The first shaft has a first locked part. The second shaft has a second locked part. The first and second shafts are interchangeable. The locking part is configured on the trunk part to lock the first and second locked parts and to hold the first and second shafts. When the first shaft is employed, the first shaft is inserted in the insertion hole. When the first shaft is employed, the locking part is configured to hold the first shaft elastically and radially inwardly. When the second shaft is employed, the second shaft is inserted in the insertion hole. When the second shaft is employed, the locking part is configured to hold the second shaft elastically and radially inwardly.
Hereafter, a top toy according to an embodiment of the present invention is explained.
This top toy 100 comprises a trunk part 10 and a shaft 20. The shaft 20 is detachable with a toy body that includes the trunk part 10, and can be exchanged with other prepared shafts. By exchanging this shaft, it is possible to change the rotation characteristics of the top toy 100.
Hereafter, details of this top toy 100 are explained.
The trunk part 10 constitutes the top structure of the top toy 100, and comprises a top plate 11, an upper layer member 12, a middle layer member 13, and a lower layer member 14.
The top plate 11 is arranged on the top surface center of the trunk part 10, and has an approximately circular shape in the plan view. Two locations facing opposite sandwiching the center of the top plate 11 overhang radially outward in an arc shape, a leg 11b that hangs downward is formed on each arc-shaped overhang part 11a, and a projecting piece 11c that overhangs radially outward is formed on the bottom edge part of the leg 11b. One end in the circumferential direction of the leg 11b is cut out in step form. A locked part 11d is formed in this stepped cutout part. This locked part 11d is used when rotationally energizing the top toy 100.
The upper layer member 12 is formed in a ring shape. Here, the upper layer member 12 has a short cylinder shape, but it is also possible to have fin-shaped projections formed on the outer periphery of the upper layer member 12. On the lower side of the upper layer member 12, a ring-shaped step part 12b that fits in the middle layer member 13 is formed, and a plurality of cylindrical female threaded bosses 12c are formed. Furthermore, a mating hole 12d is formed on the bottom surface of the upper layer member 12. The top plate 11 is inserted from below in the opening at the center of the upper layer member 12. At this time, the projecting piece 11c of the top plate 11 abuts the bottom surface of the upper layer member 12, preventing the top plate 11 from coming out upward. An arc-shaped recess is formed between the outer periphery of the top plate 11 and the inner periphery of the upper layer member 12 between adjacent arc-shaped overhang parts 11a of the top plate 11.
This arc-shaped recess is used when rotationally energizing the top toy 100.
The middle layer member 13 is formed in a disk shape. Fin-shaped projections, for example, may also be formed on the outer periphery of the middle layer member 13. On the top surface of the middle layer member 13, a ring-shaped recess 13b is formed centered on the shaft 20, and a ceilinged cylindrical bulging part 13c is formed at the center. The lower side of the bulging part 13c is hollow. A hole 13h through which a core rod 15b of a disk 15 described later is inserted is formed on the ceiling of the bulging part 13c. Furthermore, fitting projections 13d that fit in mating holes 12d of the upper layer member 12 are erected on the outer periphery part of the middle layer member 13. Insertion through holes 13e corresponding to the bosses 12c of the upper layer member 12 are formed on the middle layer member 13. Then, by screwing male screws (not illustrated) that pass through the insertion through holes 13e from below the middle layer member 13 into the female threads of the bosses 12c, the middle layer member 13 is attached to the upper layer member 12. At this time, the top plate 11 is covered by the bulging part 13c, the projecting pieces 11c of the top plate 11 ride on the recess 13b of the middle layer member 13, and the projecting pieces 11c are pinched by the upper layer member 12 and the middle layer member 13.
As shown in
The lower layer member 14 is formed in a round tray shape. Fin-shaped projections, for example, may be formed on the outer periphery of the lower layer member 14. A ring-shaped recess 14b centered on the shaft 20 is formed on the top surface of the lower layer member 14, and a ceilinged cylindrical bulging part 14c is formed in the center. The lower side of this bulging part 14c is hollow. A portion of the wall of the bulging part 14c is cut out. Engaging pieces 14e that engage with the engaging pieces 13f are formed on this cutout part 14d.
For engaging of the engaging pieces 13f and the engaging pieces 14e, the bulging part 13c of the middle layer member 13 is made to cover the bulging part 14c of the lower layer member 14, the lower layer member 14 and the middle layer member 13 are superimposed, and the middle layer member 13 is rotated relatively clockwise with respect to the lower layer member 14. At this time, the top surface of the engaging pieces 13f and the bottom surface of the engaging parts 14e are abutted. At this time, the claws of the elastic positioning pieces 13g are fitted in grooves 14f on the bulging part 14c for positioning.
A plurality of female threads 14g are formed on the bottom surface of the lower layer member 14. A hole 14h is formed in the center of the lower layer member 14.
A tack-shaped member 15 supports the shaft 20.
The tack-shaped member 15 comprises a disk 15a constituting a head, and the core rod 15b is provided perpendicularly at the center of the disk 15a.
Inside the trunk part 10, the disk 15 is provided between the top plate 11 and the bulging part 13c of the middle layer member 13, and can rotate around the shaft 20. The cross section of the core rod 15b is a square shape, and passes through the hole 13h of the middle layer member 13. This core rod 15b is internally fitted in the shaft 20 described later.
The bottom structure is constituted from a shaft mounting member 31 and the shaft 20, and the shaft mounting member 31 together with the trunk part 10 constitute the toy body. This toy body is constituted mostly from plastic. It may also of course include metal.
The shaft mounting member 31 is provided under the lower layer member 14.
The shaft mounting member 31 comprises a locking ring 32 and a ring support member 33.
On the locking ring 32, three hanging downward insertion parts 32a and elastic pieces 32b each are formed alternately in the circumferential direction. This number is not limited to being three. It is also possible to use one elastic piece 32b, for example.
Of these, the insertion parts 32a are constituted from a bottom-view arc-shaped first insertion piece 320a, and a second insertion piece 321a extending outward from the circumferential direction center of the outer surface of the first insertion piece 320a.
On the bottom part inside of the elastic pieces 32b are formed claws (locking parts) 320b having a slope in four directions in the form of a hipped roof.
Meanwhile, the ring support member 33 is formed in a bowl shape, and has an insertion hole 33a of the shaft 20 formed in the center.
On the inner periphery surface of the ring-shaped member 33, a pair of projections 33b, 33b are formed facing each other with the second insertion piece 321a inserted therebetween.
On the inner periphery part of the ring-shaped bottom surface of the ring support member 33, projections 33c are formed so that the first insertion pieces 320a can be inserted between them and the projections 33b.
Furthermore, on the upper part outer periphery of the ring support member 33, three outward facing projecting pieces 33e in which insertion through holes 33d are formed at equal intervals in the circumferential direction.
By screwing male screws (not illustrated) passed through the insertion through holes 33d from below the ring support member 33 into the female threads 13e of the lower layer member 14, the ring support member 33 is attached to the lower layer member 14. Before this, the locking ring 32 is assembled inside the ring support member 33.
A circular hole is formed on the top end of the shaft 20, and the core rod 15b is inserted in this hole. In this case, the shaft 20 fits with respect to the core rod 15b. The shaft 20 is not limited to being a single component, and may also be configured by joining a plurality of components.
A constricted part (locked part) 21 is formed in the vertical direction center part of the shaft 20, and the claws 320b of the elastic pieces 32b are fitted in this constricted part 21. As a result, the shaft 20 is picked up and held by the claws 320b. Gear 22 is formed on the constricted part 21, and the claws 320b mesh with the gear 22.
Below the constricted part 21, a flange part 22 is formed that overhangs radially outward. The flange part 22 is fitted into the bottom surface of the ring support member 33 when the shaft 20 is inserted into the insertion hole 33a of the ring support member 33 from below.
Gear 23 that meshes with teeth 93a of a battle stadium 90 described later is formed below the flange part 22.
A rotational resistance part R1 is a frictional resistance part that is created by sliding contact between the disk 15a that rotates integrally with the shaft 20 and the top plate 11.
A rotational resistance part R2 is a frictional resistance part that is created by sliding contact between the disk 15a and the middle layer member 13.
A rotational resistance part R3 is a frictional resistance part that is created by sliding contact between the lower layer member 13 and the outer circumference of the shaft 20.
A rotational resistance part R4 is a frictional resistance part that is created by sliding contact between the side wall of the constricted part 21 and the claws 320b. Also, a rotational resistance part R5 is a frictional resistance part that is created by sliding contact between the bottom wall of the constricted part 21 and the claws 320b. This is when there is no gear 22 on the constricted part 21, and when there is a gear 22 on the constricted part 21, rotational resistance is created on the basis of meshing as rotational resistance between the gear 22 and the claws 320b.
A rotational resistance part R6 is a frictional resistance part that is created by sliding contact between the outer periphery of the flange part 22 and the shaft mounting member 31.
Of these, the rotational resistance parts R3 to R6 are rotational resistance that is created by sliding contact directly between the toy body and the shaft 20, and by exchanging of the shaft 20, if the diameter of the shaft 20 and the depth or shape, etc., of the constricted part 21 are changed, it is possible to change the rotational resistance.
The top shooting device 80 comprises a top holder 81 that holds the rotationally energized top toy 100. The top holder 81 is provided with two insertion pieces 81a corresponding to the arc-shaped recess of the top toy 100. A locking part 81b that projects in the rotationally energized direction is formed on the insertion piece 81a. After the insertion piece 81a is inserted in the arc-shaped recess of the top toy 100, the top toy 100 is rotated relatively in the direction opposite to the rotationally energized direction of the top toy 100 with respect to the top holder 81, and by the locking part 81b getting under the locked part 11d of one end part of the arc-shaped recess, the top toy 100 is attached to the top holder 81.
A handle 82 is provided on the top shooting device 80, and one end of a cord (not illustrated) is attached to this handle 82. The cord is wound on an input rotor (not illustrated) by the restoring force of a mainspring, and by operating the handle 82 to pull the cord, rotational force is inputted to the input rotor. The input rotor is coupled to the top holder 81, which is rotated by the rotation of the input rotor.
With this top shooting device 80, the top toy 100 attached to the top holder 81 is rotationally energized by rotating the top holder 81 by operating the handle 82. When operation of the handle 82 is stopped, while rotation of the top holder 81 stops, the top toy 100 continues rotating due to inertial force, so the locking part 81b separates from below the locked part 11d of the arc-shaped recess and the top toy 100 is shot. Here, the input rotor coupled to the top holder 81 was rotated using a cord, but it is also possible to use a gear for the input rotor coupled to the top holder 81, with the gear rotated by a rack belt having a belt part on which a rack is formed.
The bottom surface of a field 91 of the battle stadium 90 is a concave curved surface, and the field 91 is covered by a transparent cover 92 with an open center. A guide section 93 on which are formed teeth 93a that mesh with the gear 23 of the shaft 20 of the top toy 100 that moves around inside the field 91 is arranged in the field 91.
With this battle stadium 90, by meshing the teeth 93a with the gear 23 of the shaft 20 of the top toy 100, the top toy 100 is rolled with respect to the guide section 93, and it is possible to increase the speed at which the top toy 100 moves around.
A shaft 20A is the same as the shaft 20. A gear 24A is formed inside a constricted part 21A. This gear 24A meshes with the claws 320b. As a result, rotation of the shaft 20 with respect to the lower layer member 14 is suppressed. Meanwhile, the tip of the shaft 20A is flat. For that reason, it is easy to move around a lot. The rotation of the shaft 20 with respect to the lower layer member 14 is also strongly suppressed by meshing of the gear 24A and the claws 320b, so when a gear 23A abuts the guide section 93, it is easy for the movement to accelerate.
In this shaft 20B, the first point that differs from the shaft 20A is that the cross section of the inside of a constricted part 21B (cross section orthogonal to the shaft 20B) is square. In this shaft 20B, the second point that differs from the shaft 20A is that a taper is formed on the tip part and the diameter of the bottom surface (tip surface) is smaller than that of the shaft 20A. As a result, compared to the case of the shaft 20A, in the top toy 100, the shaft 20 rotates more easily with respect to the lower layer member 14, and the diameter of the tip is smaller, so it doesn't move around easily.
When the lower layer member 14 and the shaft 20B rotate relatively around the shaft 20B, the polygonal surface (sliding contact surface) of the constricted part 21B generates frictional resistance by having sliding contact with the claws 320b, and since the rotation of the shaft 20 with respect to the lower layer member 14 is suppressed to a degree, when a gear 23B abuts the guide section 93, though not as much as with the shaft 20A, the movement is accelerated. At that time, rotation of the shaft 20 with respect to the lower layer member 14 is done to a degree, so, it is easier to bite into the guide section 93 compared to the shaft 20A.
In a shaft 20C, the bottom cross section of a constricted part 21C is circular, and the tip part is pointed like a cone. As a result, movement is not accelerated easily when a gear 23C abuts the guide section 93, but it easily bites into the guide section 93, so the top toy 100 is not repelled easily by the guide section 93, and movement along the guide section 93 is easier. In this case, by changing the shape or thickness of the constricted part 21 is changed, when the lower layer member 14 and the shaft 20C rotate relatively around the shaft 20C, it is possible for the surface (sliding contact surface) of the constricted part 21C to be in sliding contact with the claws 320b and generate frictional resistance, or to change the size of the frictional resistance.
The features of these shafts 20A to 20C can be combined freely as long as they do not contradict each other.
In the above embodiments, the shaft 20, etc., was held by the constricted part (locked part) 21, etc., being picked up by the elastic pieces 32b having the claws (locking parts) 320b, but as shown in
Also, with the above embodiments, the disk 15 was provided to be able to rotate around the shaft 20 between the top plate 11 and the bulging part 13c of the middle layer 13, but the disk 15 may also be provided without being able to rotate. It is also possible to provide the core rod 15b fixed to the top plate 11 and the middle layer member 31. Furthermore, by making the rotation of the disk 15 dull by friction, it is possible to provide a function of suppressing the rotation of the shaft 20 to some degree.
Furthermore, with the embodiments, the gear 23 was fixed to the shaft 20, but it is also possible to provide it to be able to spin idly in relation to the shaft 20.
The invention is not limited to having the teeth 93a formed on the guide section 93 with the gear 23 provided on the shaft 20, etc. The invention can also be applied to items in which teeth 93a do not exist on the guide section 93. It is sufficient provided that the movement of the top toy 100 can be changed by the outer periphery of the shaft 20, etc., of the top toy 100 abutting, and the shaft 20 rolling. For example, it is possible to constitute the entirety or the surface layer of the outer periphery of the shaft 20, etc., using rubber, to create stronger friction than a normal case (plastic or metal). In this case, it is also possible to configure the part that creates strong friction using a roller that overhangs radially outward from the shaft 20, etc.
In the above embodiments, the cross section of the core rod 15b was square, and the core rod 15b was internally fitted in the shaft 20, but it is also possible to fit the shaft head in the hole part instead of the core rod 15b.
In the above embodiments, the configuration was such that the shaft 20 rotates integrally with the core rod 15b, but it is also possible to configure so that the shaft 20 can rotate with respect to the core rod 15b.
Furthermore, in the above embodiments, the constricted part (locked part) 21, etc., was provided on the shaft 20 and the claws (locking parts) 320b were fitted in this, but it is also possible to configure by providing flange-shaped projections (locked parts) of the shaft 20, so that the shaft 20 is prevented from coming out by locking using locking parts such as the claws, etc.
The modifications above can be combined freely provide they do not contradict each other.
The top toy of the present invention can be suitably used in the field of top toy manufacturing.
According to the present invention, by engaging the locking part using elastic force to the locked part provided on the shaft, the shaft is held, so it is possible to exchange the shaft easily, and the rotation characteristics can be changed.
