Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above spinning top toy, the shaft cannot be pushed deeper into the shaft support portion from the state where the constricted portion is held by the elastic locking portion. For example, in the state where the constricted portion is pinched by the elastic locking portion, the flange immediately below the constricted portion abuts against the lower surface of the shaft support portion, and the shaft cannot be pushed deeper into the shaft support portion. Therefore, when the spinning top toy is launched and lands on the floor, a large landing impact acts on the spinning top toy. Then, due to this landing impact, the spinning top toy bounces, resulting in a loss of rotational energy, and it is difficult to land the spinning top toy at a desired position on the floor. The present invention has been made in view of such circumstances, and an object thereof is to provide a spinning top toy that can reduce energy loss due to landing impact and land the spinning top toy at a desired position on the floor.

Means for Solving the Problems

[0005] The first means is a spinning top toy provided with an elastic locking portion that elastically holds a constricted portion of a shaft inserted into a shaft hole formed in a shaft support portion, The shaft is configured to be movable in the axial direction so that it can take a first position in which it is locked by the elastic locking portion and a second position in which it penetrates deeper into the shaft hole than the first position. The elastic locking portion has a first sliding contact portion formed therein. The shaft has a second sliding contact portion that slides against the first sliding contact portion when the shaft moves in the axial direction. The elastic locking portion elastically deforms due to the sliding contact when the shaft is pushed into the shaft hole by the impact of landing, and moves the shaft to the first position due to the sliding contact caused by the elastic force when the impact of landing ceases. This is a spinning top toy characterized by the following:

[0006] The second means is the first means, characterized in that at least one of the first sliding contact portion and the second sliding contact portion is an inclined surface.

[0007] The third means is the first means, characterized in that the shaft has a flange formed below the constricted portion, which contacts the lower surface of the shaft support portion when the shaft is in the second position.

[0008] The fourth means is any of the first to third means, characterized in that the shaft is configured to be insertable and detachable from the shaft hole.

[0009] The fifth means is any of the first to third means, characterized in that the constricted portion has a recess formed therein, which is separated in the circumferential direction by a partition and a portion of which fits into the elastic locking portion. [Effects of the Invention]

[0010] According to the present invention, when the shaft is pushed into the shaft hole by the impact of landing, the elastic locking portion elastically deforms, thereby absorbing the impact energy, and thus preventing the spinning top toy from bouncing as much as possible. As a result, the loss of rotational energy can be reduced, and the spinning top toy can be landed at a desired position on the floor. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0012] 《First Embodiment》 FIG. 1 is a perspective view of the spinning top toy 100 of the embodiment. This spinning top toy 100 includes a body part 10 composed of an upper body part 11 and a lower body part 12, and a rod-shaped shaft (rod-shaped axis) 20.

[0013] 《Spinning Top Toy 100》 The spinning top toy 100 is generally composed of plastic.

[0014] 〈Upper Body Part 11〉 FIG. 2 is a perspective view of the upper body part 11 seen from below. The upper body part 11 is not particularly limited, but is a composite body formed by assembling a plurality of parts. The upper body part 11 includes, for example, a metal flywheel. Here, the upper body part 11 is shown as a short cylindrical shape, but irregularities may be formed on the outer periphery.

[0015] An insertion hole 11b is formed in the lower center of the upper body portion 11 within a circular recess 11c into which the shaft head 21 (Figure 6) of the shaft 20 is inserted.

[0016] <Lower torso section 12> A. Overall Figure 3 is a perspective view of the lower torso 12, and Figure 4 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 3 and 4. 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 main body 13 of the lower cylinder bulges downward in an inverted truncated cone shape (see Figure 8). 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 5 shows the shaft locking structure of the shaft 20 by the shaft locking member 14 with the lower body 13 removed.

[0017] 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.

[0018] 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.

[0019] 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. Additionally, 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 downward so that the elastic locking portion 14c is 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.

[0020] (Connecting structure between the upper body section 11 and the lower body section 12) The upper body portion 11 and the lower body portion 12 are superimposed on the shaft 20 in the vertical direction with their respective central axes aligned, and are joined, for example, by screws. Alternatively, the upper body portion 11 and the lower body portion 12 are abutted together from the axial direction at a first relative rotation position around the shaft 20, and then rotated relative to each other around the shaft 20 to a second relative rotation position, causing the lower surface of the connecting piece (not shown) of the lower body portion 12 and the upper surface of the connecting piece (not shown) of the upper body portion 11 to come into contact and join together.

[0021] <Axis 20> Figure 6 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.

[0022] 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. The lower surface of the constricted portion 26 is an inclined surface 26a that slopes downward in the radially outward direction (see Figure 6). This inclined surface 26a constitutes the second sliding contact portion.

[0023] The shaft 20 is movable in the axial direction so that it can take on a first position in which it is gripped by the claws 14e and a second position in which it enters the shaft hole 13a to a position higher (deeper) than the first position. When the shaft 20 moves, the inclined surface (second sliding contact portion) 26a slides against the claws 14e. In other words, the lower surface of the claws 14e is an inclined surface and constitutes the first sliding contact portion that slides against the second sliding contact portion. According to this structure, when the shaft 20 moves to the second position within the shaft hole 13a due to the impact of landing, the claw 14e elastically deforms and stores energy through sliding contact with the inclined surface 26a, and when the impact of landing stops, the shaft 20 moves back to the first position through sliding contact with the inclined surface 26a due to the stored elastic force.

[0024] A large flange 27 is formed below the constricted portion 26. The large flange 27 constitutes part of the protruding portion 20B. When the shaft 20 is in the first position, gripped by the claws 14e, the large flange 27 is spaced apart from the lower surface of the lower body portion 12. When the shaft 20 is in the second position, deeply inserted into the shaft hole 13a, the large flange 27 abuts against the lower surface of the lower body portion 12. 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 6, 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. This protrusion is optional.

[0025] (Movement of axis 20) Figure 7 shows the changes in the shaft 20 and the shaft locking member 14 upon landing, and Figure 8 shows the changes in the spinning top toy 100 upon landing. Before landing, the constricted portion 26 and the claw 14e are engaged (Figure 7(A)), and the shaft 20 is protruding downward from the lower body portion 12 (Figure 8(A)). When the shaft 20 moves in the direction of the second position due to the impact of landing from this state, the pair of claws 14e, 14e are pushed apart by the sliding contact between the second sliding contact portion of the constricted portion 26 and the first sliding contact portion of the claw 14e, and the elastic locking portion 14c is elastically deformed (Figure 7(B)). As the shaft 20 moves, the shaft 20 is pushed into the lower body portion 12, so the large flange 27 comes into contact with the lower surface of the lower body portion 12 (Figure 8(B)). Subsequently, once the landing impact subsides, the claw 14e moves in a direction that eliminates the deflection of the elastic locking portion 14c due to the stored elastic force, and the sliding contact between the second sliding contact portion of the constricted portion 26 and the first sliding contact portion of the claw 14e pushes the shaft 20 back to the first position (Figure 7(C)). This movement of the shaft 20 returns it to a state where it protrudes downward from the lower body portion 12 (Figure 8(C)).

[0026] With the above shaft structure and shaft locking structure, the elastic locking part 14c elastically deforms when the shaft 20 is pushed into the shaft hole 13a due to landing impact, thereby absorbing the impact energy, and thus preventing the spinning top toy 100 from bouncing as much as possible. As a result, the loss of rotational energy can be reduced, and the spinning top toy 100 can be landed at a desired position on the floor.

[0027] 《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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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 with an opening in the center. The field 91 is provided with a guide section 93 having teeth 93a formed on it 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. 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.

[0032] For example, in the above embodiment, the lower surface of the constricted portion 26 is made into an inclined surface (sliding contact portion) 26a that slopes downward radially outward, but the inclined surface (sliding contact portion) may extend down to the insertion portion 20A below that. The point is that the shaft 20 and the elastic locking portion 14c are provided with sliding contact portions that do not hinder the movement of the shaft 20 and that slide against each other when moving.

[0033] Furthermore, in the above embodiment, instead of the elastic locking portion 14c, the shaft 20 may be locked by two or more locking portions that are reciprocable in the radial direction and biased radially inward by a coil spring. [Explanation of Symbols]
