Description

[Technical Field]

[0001] The present invention relates to a toy top. [Background technology]

[0002] Conventionally, a known top toy has been known which has a body having a first connecting portion and an axis having a second connecting portion, and which is configured such that the axis and body are butted together from above and below with their centerlines aligned, and the body is rotated in one direction relative to the axis, thereby bringing the upper surface of the first connecting portion into contact with the lower surface of the second connecting portion, thereby connecting the axis and body (see, for example, Patent Document 1). This toy top is used, for example, in a battle game in which players collide with each other and compete to break down the opponent's toy top faster than their own. In this case, the toy top breaks down as the body is rotated in different directions relative to the axis during the battle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5959773 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned top battle game, it is desirable that the tops be broken down after several battles have been played. If the tops were broken down immediately, the battle would end in an instant before the thrill of the battle could be fully enjoyed, and the thrill of the battle would not be fully enjoyed. Therefore, in the above-mentioned top toys, a gimmick is employed that adds a certain degree of rotational resistance when the body is rotated in the other direction relative to the axis. Specifically, in the above-mentioned conventional technology, an upward protrusion was provided on the upper surface of the shaft portion and an uneven portion was provided on the lower surface of the body portion, and the protrusion and the uneven portion were engaged from above and below by the biasing force of a coil spring. SUMMARY OF THE INVENTION An object of the present invention is to provide a toy top having a simple connecting structure between a lower rotating body and an upper rotating body, which differs from the above-mentioned prior art. [Means for solving the problem]

[0005] The first method is a top toy comprising a lower rotating body and an upper rotating body that are stacked on top of each other in the axial direction and can rotate relatively around an axis, the lower rotating body and the upper rotating body being butted together in the axial direction at a first relative rotation position, and then being rotated relatively around the axis to a second relative rotation position, whereby a lower surface of a connecting piece of the lower rotating body comes into contact with an upper surface of a connecting piece of the upper rotating body, thereby connecting the lower rotating body and the upper rotating body, and the lower rotating body and the upper rotating body being separated when a predetermined external force is applied to the lower rotating body and the upper rotating body to rotate them relatively from the second relative rotation position to the first relative rotation position, A first engagement portion is fixedly provided on the lower rotating body, The upper rotating body has: a second engaging portion that is fixedly provided and abuts against the first engaging portion from a radial direction of the shaft at least when the lower rotating body and the upper rotating body rotate relative to each other; The first engaging portion and the second engaging portion are At least one of the first engaging portion and the second engaging portion has elasticity, When the engagement portions are rotated relative to each other from the first relative rotation position to the second relative rotation position, the engagement portions are elastically deformed by sliding contact with each other, and then the engagement portions are engaged with each other at the second relative rotation position due to the elasticity of the engagement portions, thereby resisting the relative rotation to the first relative rotation position. It is a top toy characterized by the following.

[0006] The second means is the first means, characterized in that the lower rotating body constitutes a lower trunk portion, and the upper rotating body constitutes an upper trunk portion.

[0007] The third means is the first means, characterized in that the lower rotating body constitutes a shaft portion, and the upper rotating body constitutes an upper body portion.

[0008] The fourth means is the second means, wherein one of the first engaging portion and the second engaging portion is configured with an arc-shaped wall having a wall surface concentric with the axis, and the other engaging portion is configured with an elastic piece on which a protrusion is formed. The protrusion is capable of slidingly contacting the wall surface of the arc-shaped wall and is capable of engaging with the end of the arc-shaped wall at the second relative rotation position.

[0009] The fifth means is the second means, wherein the first engagement portion is configured by an elastic piece having an outward protrusion, and the second engagement portion is configured by an arc-shaped wall having a wall surface concentric with the axis, The protrusion is capable of slidingly contacting the inner surface of the arc-shaped wall and is capable of engaging with the end of the arc-shaped wall at the second relative rotation position.

[0010] A sixth aspect is the fourth aspect, characterized in that the first engaging portion and the second engaging portion are provided in plural, and the plural first engaging portions are integrally configured.

[0011] The seventh means is any one of the first to sixth means, characterized in that the lower rotating body and the upper rotating body are connected by the coupling between the lower rotating body and the upper rotating body and the engagement between the first engaging portion and the second engaging portion. [Effects of the Invention]

[0012] According to the present invention, when the first engagement portion and the second engagement portion are rotated relative to each other from the first relative rotation position to the second relative rotation position, at least one of the engagement portions elastically deforms due to sliding contact with each other, and then at the second relative rotation position, the first engagement portion and / or the second engagement portion engage with each other due to the elasticity of the first engagement portion and / or the second engagement portion, thereby resisting relative rotation to the first relative rotation position, thereby realizing a top toy with a simple connection structure between the lower rotating body and the upper rotating body that has never been seen before.

DETAILED DESCRIPTION OF THE INVENTION

[0014] First Embodiment FIG. 1 is a perspective view of a toy top 100 according to an embodiment, and FIG. 2 is a perspective view showing the toy top 100 disassembled for use in a top battle. This toy top 100 is used, for example, in a top battle in which the toy tops 100 are collided with each other to fight. This toy top 100 has a body 10 composed of an upper body 11 and a lower body 12, and a rod-shaped shaft (rod-shaped shaft) 20. As shown in FIG. 2, this toy top 100 can be disassembled into two parts, an upper body 11 and a lower body 12 and a shaft 20, as a result of a top battle.

[0015] 100 Top Toys The toy top 100 is generally made of plastic.

[0016] <Upper body 11> FIG. 3 is a perspective view of the upper body portion 11 as seen from below. Although not particularly limited, upper body 11 is a composite formed by assembling multiple parts. Upper body 11 includes, for example, a metal flywheel. Although upper body 11 is shown here as a short cylinder, it may have an irregular outer periphery. Two arc-shaped grooves 11a (FIG. 1) are formed at a predetermined interval in the circumferential direction on the inner periphery of the top surface of the upper body 11, extending concentrically with the axis 20. However, the number of arc-shaped grooves 11a is not limited to two. These arc-shaped grooves 11a are used to rotate the toy top 100.

[0017] An insertion hole 11b, into which shaft head 21 (FIG. 8) of shaft 20 is inserted, is formed in circular recess 11c at the center of the lower side of upper body 11. Furthermore, a pair of arc-shaped walls 11d, 11d are vertically extended from the edge of recess 11c, facing each other with their concave surfaces facing inward. An annular portion 14a of shaft locking member 14, which will be described later, is loosely fitted into the area sandwiched between this pair of arc-shaped walls 11d, 11d. A wall 11e is provided at each end of the two arc-shaped walls 11d, 11d, and projects radially outward in a horn-like shape. A connecting piece 11f that protrudes radially outward like a canopy is formed on the outer side of one end of each arc-shaped wall 11d. This connecting piece 11f is used to connect the upper body 11 and the lower body 12. Note that a connecting piece 11f may also be formed on the outer side of the other end of each arc-shaped wall 11d. In this way, the upper body 11 can be used as a bi-directional spinning top toy. Furthermore, one end of each arc-shaped wall 11d constitutes an engaging portion (second engaging portion) 11g with which a protrusion (first engaging portion) 14g, which will be described later, engages.

[0018] <Lower torso 12> A. Overall Figure 4 is a perspective view of the lower torso section 12, and Figure 5 is an exploded perspective view of the lower torso section 12. In the description of this lower torso section 12, the terms "left and right," "front and back," and "up and down" refer to the directions indicated by arrows in Figures 4 and 5. The lower body 12 is composed of a lower body main body 13 and a shaft locking member 14. The central portion of the lower surface of the lower body main body 13 bulges downward in an inverted frustum shape (see FIG. 2). Lower body main body 13 is formed with shaft hole 13a that passes vertically through lower body main body 13. Furthermore, shaft locking member 14 is fitted and fixed into lower body main body 13 from above, and shaft 20 inserted into shaft hole 13a from below is locked by shaft locking member 14. Figure 6 shows the locking structure of shaft 20 by shaft locking member 14 with lower body main body 13 removed.

[0019] B. Shaft locking member 14 The shaft locking member 14 has a thick, short cylindrical annular portion 14a, a pair of elastically locked portions 14b, 14b for fixing the shaft locking member 14 itself to the lower body main body 13, and a pair of elastic locking portions 14c, 14c for locking the shaft 20. Each of the pair of elastically locked portions 14b, 14b is L-shaped and hangs down from the annular portion 14a, with its lower end bent outward to form an outward protrusion 14d. The pair of elastically locked portions 14b, 14b are provided at positions facing each other across the center line of the shaft locking member 14. Each of the pair of elastic locking portions 14c, 14c is vertically attached to the annular portion 14a, and has an inward-facing claw 14e formed at its lower end. The pair of elastic locking portions 14c, 14c are provided at positions facing each other across the center line of the shaft locking member 14.

[0020] C. Lower body body 13 A pair of arc-shaped walls 13b, 13b are formed on the front and rear edges of the shaft hole 13a on the upper surface of the lower body main body 13. When the shaft locking member 14 is attached to the lower body main body 13, the pair of arc-shaped walls 13b, 13b fit inside the annular portion 14a. Furthermore, three-sided walls 13c that are concave in top view toward the shaft hole 13a are formed on the outer sides of each arc-shaped wall 13b on the upper surface of the lower body main body 13. The three-sided walls 13c are provided to correspond to the elastically locked portions 14b, and are located outside the shaft locking member 14 when the shaft locking member 14 is attached to the lower body main body 13. Between the arc-shaped wall 13b and the three-sided walls 13c on its outer side, there is formed a rectangular hole 13d into which the elastically locked portion 14b can be inserted. When attaching the shaft locking member 14 to the lower body main body 13, the elastically locked portion 14b is inserted into this rectangular hole 13d from above, and the protrusion 14d of the elastically locked portion 14b slips under the floor surrounded by the three-sided walls 13c and engages due to its elasticity. In this way, the shaft locking member 14 is fixed to the lower body main body 13.

[0021] Grooves 13e in which elastic locking portions 14c are disposed are formed on the left and right sides of the hole wall that forms shaft hole 13a. Furthermore, walls 13f are formed on the upper surface of lower body main body 13, standing from the edges of grooves 13e, corresponding to the elastic locking portions 14c. By pressing shaft locking member 14 downward so that elastic locking portions 14c are positioned inside walls 13f, elastic locking portions 14c enter grooves 13e. When inserted into grooves 13e, the tips of claws 14e of elastic locking portions 14c protrude into shaft hole 13a.

[0022] (Connection structure between upper body 11 and lower body 12) The upper body 11 is formed with a pair of connecting pieces 11f, 11f, and the lower body main body 13 is formed with a pair of connecting pieces 13h, 13h.

[0023] Additionally, elastic engagement portions 14f, which are first engagement portions, are formed at predetermined intervals around the outer periphery of the annular portion 14a. The elastic engagement portions 14f are elastic pieces defined by U-shaped notches (not shown), with protrusions 14g formed at the tips thereof. The distance from the center line of the shaft locking member 14 to the distal end of the protrusions 14g is greater than the distance between the center line of the upper body 11 and the inner surface of the arc-shaped wall 11d. Four elastic engagement portions 14f are formed around the circumference of the annular portion 14a, so that the upper body 11 can be used for counter-rotating or bi-rotating top toys.

[0024] (Connection between upper body 11 and lower body 12) The lower surface of the upper body section 11 and the upper surface of the lower body section 12 are butted against each other so that the pair of arc-shaped walls 11d, 11d of the upper body section 11 are positioned inside the pair of connecting pieces 13h, 13h of the lower body section 12 (FIG. 7(A)). At this time, the butting brings the elastic engaging portion 14f into sliding contact with the inner surface of the arc-shaped wall 11d, causing the elastic engaging portion 14f to elastically deform. Next, the upper body section 11 is rotated counterclockwise relative to the lower body section 12. During this time, the elastic engagement section 14f remains in sliding contact with the inner surface of the arc-shaped wall 11d, and therefore maintains its elastically deformed state. Then, the pair of connecting pieces 11f, 11f of the upper body section 11 is slipped under the pair of connecting pieces 13h, 13h of the lower body section 12. As a result, the upper surfaces of the pair of connecting pieces 11f, 11f come into contact with the lower surfaces of the pair of connecting pieces 13h, 13h, joining the upper body section 11 and the lower body section 12. At this time, the elastic engaging portion 14f exceeds one end of the arc-shaped wall 11d, and the elasticity of the elastic engaging portion 14f causes the elastic engaging portion 14f to engage with the engaging portion 11g of the upper body section 11 (FIG. 7(B)).

[0025] <Axis 20> FIG. 8 is a perspective view of the shaft 20. The shaft 20 is rod-shaped. The shaft 20 includes an insertion portion 20A that can be inserted into the shaft hole 13a, and a protrusion portion 20B that protrudes downward from the lower body portion 12. The insertion portion 20A and the protrusion portion 20B are fitted together in the axial direction and connected to each other by a pin (not shown). The lower end of the protrusion portion 20B forms a ground contact portion.

[0026] The shaft 20 is configured to be detachable from the lower part of the shaft hole 13a. The shaft 20 is also replaceable with another shaft having different rotation characteristics. However, the shaft 20 does not have to be configured to be detachable. A shaft head 21 at the upper end of the insertion portion 20A is inserted into the insertion hole 11b of the upper body portion 11 when the insertion portion 20A is inserted into the shaft hole 13a. Furthermore, a small flange 23 is formed on the insertion portion 20A, and a constricted portion 26 is formed around the entire circumference directly below the small flange 23. This constricted portion 26 is divided into circumferential sections by partitions, and the claws 14e can fit into the divided recesses. By fitting the recesses of this constricted portion 26 into the claws 14e, the claws 14e engage with the constricted portion 26, and the shaft 20 is clamped by the claws 14e (see FIG. 6).

[0027] A large flange 27 is formed below the constricted portion 26. The large flange 27 constitutes a part of the protruding portion 20B. The large flange 27 abuts against the lower surface of the lower body portion 12 when the shaft 20 is clamped by the claws 14e. Additionally, on the protruding portion 20B, below the large flange 27, a gear 28 is formed that meshes with teeth 93a of the battle stadium 90, which will be described later. In addition, the portion indicated by the reference numeral 20a in FIG. 8 is a ridge that engages with a fixed portion within the toy top 100 and has a rotation prevention function.

[0028] "Disassembling 100 spinning tops" In a top battle, when an opponent's toy top hits lower body 12, for example, an external force acts on lower body 12 in the direction opposite to the rotation of toy top 100. This causes lower body 12 to stop rotating, while upper body 11 attempts to continue rotating due to inertial force. In other words, lower body 12 and upper body 11 attempt to rotate relative to each other. At this time, elastic engaging portion 14f is engaged with engaging portion 11g at one end of arc-shaped wall 11d, so that the relative rotation is resisted. However, if the external force is large, elastic engaging portion 14f disengages from engaging portion 11g at one end of arc-shaped wall 11d. Then, through sliding contact between the elastic engagement portion 14f and the inner surface of the arc-shaped wall 11d, the lower body portion 12 and the upper body portion 11 reach a relative rotation position where they can be disassembled, that is, a relative rotation position where the lower body portion 12 and the upper body portion 11 are released from contact between the pair of connecting pieces 13h, 13h and the pair of connecting pieces 11f, 11f. At this position, the upper body 11, the lower body 12 and the shaft 20 are disassembled into two parts.

[0029] Top Launcher 80 FIG. 9 is a perspective view showing an example of a top launcher 80. The top launching device 80 includes a top holder 81 that holds a toy top 100 that is urged to rotate. The top holder 81 is provided with the same number of insertion pieces 81a that correspond to the arc-shaped grooves 11a of the toy top 100. The insertion pieces 81a are formed with locking portions 81b that protrude in the direction of rotation. After the insertion pieces 81a are inserted into the arc-shaped grooves 11a of the toy top 100, the toy top 100 is rotated relative to the top holder 81 in the direction opposite to the direction of rotation of the toy top 100, and the locking portions 81b are inserted under the edge wall of one end of the arc-shaped grooves 11a, whereby the toy top 100 is attached to the top holder 81.

[0030] The top launching device 80 is provided with a handle 82, to which one end of a string (not shown) is attached. The string is wound around an input rotor (not shown) by the restoring force of a spring, and by operating the handle 82 and pulling out the string, a rotational force is input to the input rotor. The input rotor is connected to a top holder 81, and is rotated by the rotation of the input rotor.

[0031] According to this top launching device 80, the toy top 100 attached to the top holder 81 is urged to rotate by rotating the top holder 81 through operation of the handle 82. When the operation of the handle 82 is stopped, the rotation of the top holder 81 stops, but the toy top 100 continues to rotate due to inertial force, so that the locking portion 81b comes off from under the edge wall at one end of the arc-shaped groove 11a, and the toy top 100 is pushed out by sliding contact with the inclined surface on the back of the insertion piece 81a, and the toy top 100 is launched.

[0032] Here, the input rotor connected to the top holder 81 is rotated by a string, but the input rotor connected to the top holder 81 may be a gear, and the gear may be rotated by a rack belt having a belt portion on which a rack is formed.

[0033] Battle Stadium 90 FIG. 10 is a perspective view showing the appearance of an example of a battle stadium 90. The bottom surface of the field 91 of the battle stadium 90 is a concave curved surface, The field 91 is covered with a transparent cover 92 that has an opening in the center. A guide portion 93 is provided in the field 91, and the guide portion 93 has teeth 93a formed thereon that mesh with the gear 28 of the shaft 20 of the toy top 100 that moves around in the field 91. According to this battle stadium 90, by meshing the gear 28 on the shaft 20 of the toy top 100 with the teeth 93a, the toy top 100 can be caused to roll relative to the guide portion 93, thereby increasing the speed at which the toy top 100 moves around.

[0034] <<Variation>> Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-described embodiments and can be modified within the scope of the gist of the present invention.

[0035] For example, in the above embodiment, one end of the arc-shaped wall 11d is the engaging portion 11g, but the engaging portion 11g may be a simple protrusion instead of the arc-shaped wall 11d. The point is that the relative rotation of the lower body portion 12 and the upper body portion 11 causes the elastic engaging portion 14f, on which the elastic engaging portion 14g is formed, to elastically deform and then elastically engage with the engaging portion 11g.

[0036] In addition, in the above embodiment, a structure has been described in which the lower rotating body is connected to the lower body 12 and the upper rotating body is connected to the upper body 11, but this connection structure can also be applied to a structure in which the lower rotating body is the shaft and the upper rotating body is the body.

[0037] In the above embodiment, the first engaging portion is the elastic engaging portion 14f and the second engaging portion is the arc-shaped wall 11d, but both may be elastic engaging portions. [Explanation of symbols]
