Description

[[Technical Field]]

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

[0002] Conventionally, there has been known a spinning top toy including a body portion having a first coupling part and a shaft portion having a second coupling part, configured such that the shaft portion and the body portion whose center lines are aligned are butted against each other from the vertical direction, and the body portion is rotated in one direction relative to the shaft portion, thereby bringing the upper surface of the first coupling part into contact with the lower surface of the second coupling part to couple the shaft portion and the body portion (see, for example, Patent Document 1). This spinning top toy is used, for example, in a battle game where spinning top toys are collided with each other and players compete to make the opponent's spinning top toy disassemble faster than their own. In this case, the disassembly of the spinning top toy is achieved when the battle causes the body portion to rotate in the other direction relative to the shaft portion.

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

[0004] By the way, in a spinning top toy battle game as described above, it is desirable that the spinning top toy is disassembled after several repeated battles. If the spinning top toy is disassembled immediately, the battle ends in an instant before players can experience the thrill and suspense, and they cannot fully enjoy the true charm of the battle. Accordingly, spinning top toys such as those described above employ a gimmick that applies a certain amount of rotational resistance when the body portion is rotated in the other direction relative to the shaft portion. Specifically, in the conventional technology described above, an upward-facing projection was provided on the upper surface of the shaft, and an uneven surface was provided on the lower surface of the body, and the projection and the uneven surface were engaged from above and below by the biasing force of a coil spring. The present invention aims to provide a spinning top toy 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]

The upper rotating body includes: A second engaging portion is fixedly provided which contacts the first engaging portion from the radial direction of the axis 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 is elastic, When the relative rotation is performed from the first relative rotation position to the second relative rotation position, at least one of the engaging portions elastically deforms due to mutual sliding contact, and then at the second relative rotation position, the elasticity of at least one of the engaging portions engages with each other to resist relative rotation to the first relative rotation position. This is a spinning top toy characterized by the following:

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

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

[0008] The fourth means is the second means, wherein one of the first and second engaging portions is an arc-shaped wall having a wall surface concentric with the axis. end The other engaging part is composed of an elastic piece on which a projection is formed. The projection is characterized in that it is slidable against the wall surface of the arc-shaped wall and can engage 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 engaging portion is composed of an elastic piece with an outward projection, and the second engaging portion is an arc-shaped wall having a wall surface concentric with the axis end It consists of, The projection is characterized in that it is slidable against the inner surface of the arc-shaped wall and, at the second relative rotation position, is capable of engaging with the end of the arc-shaped wall.

[0010] The sixth means is the fourth means, characterized in that it comprises a plurality of the first engaging portion and the second engaging portion, and the plurality of the first engaging portions are integrally configured.

[0011] The seventh means is any of the first to sixth means, characterized in that the lower rotating body and the upper rotating body are connected by a coupling between the lower rotating body and the upper rotating body and by 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 engaging portion and the second engaging portion are relatively rotated from the first relative rotational position to the second relative rotational position, after at least one of the engaging portions is elastically deformed by mutual sliding contact, the first engaging portion and / or the second engaging portion engage with each other at the second relative rotational position by the elasticity of the first engaging portion and / or the second engaging portion to resist relative rotation back to the first relative rotational position, whereby a spinning top toy having an unprecedented simple connecting structure of a lower rotating body and an upper rotating body can be realized.

[0014] <<First Embodiment>> FIG. 1 is a perspective view of a spinning top toy 100 according to an embodiment, and FIG. 2 is a perspective view showing how the spinning top toy 100 is disassembled during a spinning top battle. This spinning top toy 100 is used, for example, in spinning top battles where spinning top toys 100 collide with each other to compete. This spinning top toy 100 includes a body portion 10 composed of an upper body portion 11 and a lower body portion 12, and a rod-shaped shaft (rod shaft) 20. As shown in Figure 2, this spinning top toy 100 can be disassembled into two parts as a result of a spinning top battle: the upper body 11 and the lower body 12 and shaft 20.

[0015] 《100 Spinning Top Toys》 The 100 spinning top toys are mostly made of plastic.

[0016] <Upper torso section 11> Figure 3 is a perspective view of the upper torso 11 as seen from below. The upper body 11 is a composite structure assembled from multiple parts, although it is not particularly limited. The upper body 11 includes, for example, a metal flywheel. Although the upper body 11 is shown here as a short cylindrical shape, its outer circumference may have irregularities. Two arc-shaped grooves 11a (Figure 1) are formed at predetermined intervals in the circumferential direction on the inner outer circumference of the upper surface of the upper body portion 11, extending concentrically with the shaft 20. However, the number is not limited to two. These arc-shaped grooves 11a are used to bias the spinning top toy 100 into rotation.

[0017] An insertion hole 11b is formed in a circular recess 11c at the lower center of the upper body portion 11, into which the shaft head 21 (Figure 8) of the shaft 20 is inserted. Furthermore, a pair of arc-shaped walls 11d, 11d are vertically installed on the edge of the recess 11c, facing each other with their concave surfaces facing inward. The annular portion 14a of the shaft locking member 14, described later, is loosely fitted into the area sandwiched between this pair of arc-shaped walls 11d, 11d. Each end of the two arc-shaped walls 11d, 11d is connected to a wall 11e that protrudes radially outward in a horn-like shape. Furthermore, a connecting piece 11f is formed on the outer side of one end of each arc-shaped wall 11d, projecting radially outward in an overhang-like manner. This connecting piece 11f is used when connecting the upper body 11 and the lower body 12. Note that the 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 is for a spinning top toy that rotates in both directions. Furthermore, one end of each arc-shaped wall 11d is as described later. Formed at the tip of the elastic engagement portion (first engagement portion) 14f The projection 14g constitutes an engaging portion (second engaging portion) 11g with which it engages.

[0018] <Lower torso section 12> A. Overall Figure 4 is a perspective view of the lower torso 12, and Figure 5 is an exploded perspective view of the lower torso 12. In this description of the lower torso 12, "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 portion 12 is composed of the lower body portion main body 13 and the shaft locking member 14. The lower central part of the lower body section 13 bulges downward in an inverted truncated cone shape (see Figure 2). The lower body 13 has a shaft hole 13a that penetrates it vertically. A shaft locking member 14 is fitted and fixed to the lower body 13 from above, and the shaft 20 inserted into the shaft hole 13a from below is locked in place by this shaft locking member 14. Figure 6 shows the shaft locking structure of the shaft 20 by the shaft locking member 14 with the lower body 13 removed.

[0019] B. Shaft locking member 14 The shaft locking member 14 comprises a thick, short cylindrical annular portion 14a, a pair of elastic locking 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 elastic locking portions 14b, 14b is L-shaped, perpendicular to the annular portion 14a, and its lower end is bent outward to form an outward projection 14d. The pair of elastic locking portions 14b, 14b are positioned opposite each other across the center line of the shaft locking member 14. Furthermore, each of the pair of elastic locking portions 14c, 14c is vertically attached to the annular portion 14a, and an inwardly facing claw 14e is formed at its lower end. The pair of elastic locking portions 14c, 14c are provided at positions opposite each other across the centerline of the shaft locking member 14.

[0020] C. Lower torso body 13 On the upper surface of the lower body 13, a pair of arc-shaped walls 13b, 13b are formed on the front and rear edges of the shaft hole 13a. The pair of arc-shaped walls 13b, 13b fit inside the annular portion 14a when the shaft locking member 14 is attached to the lower body 13. Furthermore, on the upper surface of the lower body 13, three-sided walls 13c are formed on the outside of each arc-shaped wall 13b, and are concave in top view toward the shaft hole 13a. The three-sided walls 13c are provided in correspondence with the elastic locking portion 14b, and are located on the outside of the shaft locking member 14 when the shaft locking member 14 is attached to the lower body 13. A rectangular hole 13d into which the elastic locking portion 14b can be inserted is formed between the arc-shaped wall 13b and the outer three-sided wall 13c. When attaching the shaft locking member 14 to the lower body 13, the elastic locking portion 14b is inserted into this rectangular hole 13d from above, and the projection 14d of the elastic locking portion 14b slides under the floor surrounded by the three-sided wall 13c and engages elastically. In this way, the shaft locking member 14 is fixed to the lower body 13.

[0021] Grooves 13e are formed on the left and right sides of the hole wall forming the shaft hole 13a, where the elastic locking portion 14c is positioned. Furthermore, a wall 13f is formed on the upper surface of the lower body 13, rising from the edge of the groove 13e, corresponding to the elastic locking portion 14c. By pushing the shaft locking member 14 downwards, with the elastic locking portion 14c positioned inside this wall 13f, the elastic locking portion 14c engages with the groove 13e. When engaged with the groove 13e, the tips of the claws 14e of the elastic locking portion 14c protrude into the shaft hole 13a.

[0022] (Connecting structure between the upper body section 11 and the lower body section 12) A pair of connecting pieces 11f, 11f are formed on the upper body portion 11, and a pair of connecting pieces 13h, 13h are formed on the lower body portion 13.

[0023] Furthermore, elastic engagement portions 14f, which are first engagement portions, are formed on the outer circumference of the annular portion 14a at predetermined intervals in the circumferential direction. The elastic engagement portion 14f has a projection 14g formed at the tip of an elastic piece partitioned by a U-shaped notch (not shown). The distance from the center line of the shaft locking member 14 to the distal end of the projection 14g is greater than the distance between the center line of the upper body portion 11 and the inner surface of the arc-shaped wall 11d. In addition, four elastic engagement portions 14f are formed in the circumferential direction on this annular portion 14a, so that the upper body portion 11 can be used for spinning tops that rotate in opposite directions or in both directions.

[0024] (Connection between the upper body section 11 and the lower body section 12) The lower surface of the upper body portion 11 and the upper surface of the lower body portion 12 are butted together such that the pair of arc-shaped walls 11d, 11d of the upper body portion 11 are positioned inside the pair of connecting pieces 13h, 13h of the lower body portion 12 (Figure 7(A)). At this time, the elastic engaging portion 14f slides against the inner surface of the arc-shaped wall 11d due to this butting, and the elastic engaging portion 14f undergoes elastic deformation. Next, the upper body portion 11 is rotated counterclockwise relative to the lower body portion 12. During this time, the elastic engagement portion 14f is in sliding contact with the inner surface of the arc-shaped wall 11d, so that the elastic engagement portion 14f maintains an elastically deformed state. Then, the pair of connecting pieces 11f, 11f of the upper body 11 are tucked under the pair of connecting pieces 13h, 13h of the lower body 12. As a result, the upper surfaces of the pair of connecting pieces 11f, 11f and the lower surfaces of the pair of connecting pieces 13h, 13h come into contact, and the upper body 11 and the lower body 12 are joined together. At this time, the elastic engaging portion 14f extends beyond 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 11 (Figure 7(B)).

[0025] <Axis 20> Figure 8 is a perspective view of axis 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 projection portion 20B that protrudes downward from the lower shaft portion 12. The insertion portion 20A and the projection portion 20B are fitted together from the axial direction and connected to each other by a pin (not shown). The lower end of the projection portion 20B forms a ground contact portion.

[0026] The shaft 20 is configured to be removable from below the shaft hole 13a. Furthermore, the shaft 20 is interchangeable with other shafts having different rotational characteristics. Note that the shaft 20 does not necessarily have to be configured to be removable. The 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 in the circumferential direction by a partition, and the claws 14e can be fitted into the divided recesses. By fitting the recesses of this constricted portion 26 with the claws 14e, the claws 14e engage with the constricted portion 26, and the shaft 20 is gripped by the claws 14e (see Figure 6).

[0027] A large flange 27 is formed below the constricted portion 26. The large flange 27 constitutes 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 gripped by the claws 14e. Furthermore, in the protruding portion 20B, a gear 28 is formed below the large flange 27 that meshes with the teeth 93a of the battle stadium 90, which will be described later. In Figure 8, the part indicated by reference numeral 20a is a protrusion that engages with the fixing part inside the spinning top toy 100 and has a function to prevent rotation.

[0028] 《100 Disassemblies of Spinning Top Toys》 In a spinning top battle, if the opponent's spinning top hits, for example, the lower body 12, an external force acts on the lower body 12 in the opposite direction to the rotation of the spinning top 100. As a result, the rotation of the lower body 12 stops, while the upper body 11 tries to continue rotating due to inertia. In other words, the lower body 12 and the upper body 11 try to rotate relative to each other. At this time, the elastic engaging part 14f and the engaging part 11g at one end of the arc-shaped wall 11d are engaged and try to resist this relative rotation, but if the external force is large, the engagement between the elastic engaging part 14f and the engaging part 11g at one end of the arc-shaped wall 11d is released. 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 separated, that is, a relative rotation position where the contact between the pair of connecting pieces 13h, 13h and the pair of connecting pieces 11f, 11f is released. At this position, the upper barrel 11 and the lower barrel 12 and shaft 20 are separated into two parts.

[0029] 《Spinning Top Launcher 80》 Figure 9 is a perspective view showing an example of a spinning top launcher 80. The spinning top launcher 80 includes a spinning top holder 81 that holds a spinning top toy 100 that is biased to rotate. The spinning top holder 81 is provided with the same number of insertion pieces 81a as the arc-shaped grooves 11a of the spinning top toy 100. The insertion pieces 81a have locking portions 81b that protrude in the direction of rotation biasing. After inserting the insertion pieces 81a into the arc-shaped grooves 11a of the spinning top toy 100, the spinning top toy 100 is rotated relative to the spinning top holder 81 in the opposite direction to the direction of rotation biasing of the spinning top toy 100, and the locking portion 81b is tucked under the edge wall of one end of the arc-shaped groove 11a, thereby attaching the spinning top toy 100 to the spinning top holder 81.

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

[0031] According to this spinning top launcher 80, the spinning top toy 100 attached to the spinning top holder 81 is biased to rotate by rotating the spinning top holder 81 through the operation of the handle 82. When the operation of the handle 82 is stopped, the rotation of the spinning top holder 81 stops, but the spinning top toy 100 continues to rotate due to inertia, causing the locking part 81b to disengage from below the edge wall at one end of the arc-shaped groove 11a, and the spinning top toy 100 is pushed out by sliding contact with the inclined surface on the back of the insertion piece 81a, and is launched.

[0032] In this example, the input rotating body connected to the spindle holder 81 is rotated by a string. However, the input rotating body connected to the spindle holder 81 may be a gear, and the gear may be rotated by a rack belt having a belt section on which a rack is formed.

[0033] Battle Stadium 90 Figure 10 is a perspective view showing an example of Battle Stadium 90. The bottom surface of Field 91 in Battle Stadium 90 is a concave curved surface, and Field 91 It is covered by a transparent cover 92 that has an opening in the center. The field 91 is provided with a guide section 93 on which teeth 93a are formed that mesh with the gear 28 of the shaft 20 of the spinning top toy 100 that moves around inside the field 91. According to this Battle Stadium 90, by engaging the gear 28 and teeth 93a of the shaft 20 of the spinning top toy 100, the spinning top toy 100 can be made to roll against the guide 93, thereby increasing the speed at which the spinning top toy 100 moves.

[0034] Variant form Although embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above embodiments and can be modified without departing from its essence.

[0035] For example, in the above embodiment, one end of the arc-shaped wall 11d is made into an engaging portion 11g, but the engaging portion 11g may not be an arc-shaped wall 11d, and the engaging portion 11g may be a simple projection. The point is that, due to the relative rotation of the lower body portion 12 and the upper body portion 11, the elastic engaging portion 14f, which has an elastic engaging portion 14g formed thereon, is elastically deformed and then elastically engages with the engaging portion 11g.

[0036] Furthermore, although the above embodiment described a structure in which the lower rotating body is connected to the lower body portion 12 and the upper rotating body to the upper body portion 11, this connection structure can also be applied to a structure in which the lower rotating body is the shaft portion and the upper rotating body is the body portion.

[0037] Furthermore, 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 Engagement portion 11g formed at one end However, both may be elastically engaged parts. [Explanation of Symbols]
