AI Technical Summary
Conventional toy tops experience energy loss and difficulty in landing at a desired position due to the impact of landing, as the shaft is prevented from further insertion by the elastic locking portion, leading to bouncing.
The shaft is configured to be movable in the axial direction, with an elastic locking portion that deforms upon impact, allowing it to transition between locked and deeper positions, utilizing inclined sliding contact surfaces to absorb impact energy and return to the locked position using elastic force.
This design reduces rotational energy loss and enables the toy top to land accurately by absorbing impact energy, preventing bouncing and maintaining stability.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a toy top. [Background technology]
[0002] BACKGROUND ART Conventionally, a toy top is known that includes an elastic locking portion that uses elastic force to clamp the narrowed portion of a shaft inserted into a shaft hole formed in a shaft support portion (Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-54986 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the above-mentioned toy top, the shaft cannot be pushed any further into the shaft support portion when the narrowed portion is held by the elastic locking portion. For example, when the narrowed portion is pinched and held by the elastic locking portion, the flange directly below the narrowed portion abuts against the underside of the shaft support portion, preventing the shaft from being pushed any further into the shaft support portion. Therefore, when the toy top is launched and lands on the floor, a large impact is applied to the toy top, which can cause the toy top to bounce, resulting in a loss of rotational energy and making it difficult to land the toy top in a desired position on the floor. The present invention has been made in view of the above circumstances, and has as its object to provide a toy top that reduces energy loss due to the impact of landing and allows the toy top to land at a desired position on the floor. [Means for solving the problem]
[0005] The first method is A toy top is provided with an elastic locking part that grips the narrowed part of the shaft inserted into the shaft hole formed in the shaft support part by elastic force, The shaft is configured to be movable in the axial direction so as to be able to take a first position where it is locked by the elastic locking portion and a second position where it enters the shaft hole more deeply than the first position, The elastic locking portion is formed with a first sliding contact portion, a second sliding contact portion that comes into sliding contact with the first sliding contact portion when the shaft moves in the axial direction; When the shaft is pushed into the shaft hole by a landing impact, the elastic locking portion is elastically deformed by the sliding contact, and when the landing impact stops, the elastic locking portion moves the shaft to the first position by the sliding contact caused by an elastic force. It is a 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 that abuts against the lower surface of the shaft support portion when the shaft is in the second position.
[0008] A fourth aspect is any one of the first to third aspects, characterized in that the shaft is configured to be insertable into and detachable from the shaft hole.
[0009] The fifth means is any one of the first to third means, characterized in that the constricted portion is formed with a recess that is separated circumferentially by a partition and a part 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 to absorb the impact energy, thereby preventing the toy top from bouncing as much as possible, thereby reducing the loss of rotational energy and allowing the toy top to land in a desired position on the floor.

[0012] First Embodiment FIG. 1 is a perspective view of a toy top 100 according to an embodiment. This toy top 100 includes a body 10 composed of an upper body 11 and a lower body 12, and a rod-shaped shaft (rod-shaped shaft) 20.
[0013] 100 Top Toys The toy top 100 is generally made of plastic.
[0014] <Upper body 11> FIG. 2 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.
[0015] At the center of the lower side of upper body 11, an insertion hole 11b into which shaft head 21 (FIG. 6) of shaft 20 is inserted is formed within circular recess 11c.
[0016] <Lower torso 12> A. Overall Figure 3 is a perspective view of the lower torso section 12, and Figure 4 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 3 and 4. 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 lower body main body 13 bulges downward in the shape of an inverted frustum (see FIG. 8). 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 5 shows the locking structure of shaft 20 by shaft locking member 14 with lower body main body 13 removed.
[0017] 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.
[0018] 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.
[0019] 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 pawls 14e of elastic locking portions 14c protrude into shaft hole 13a.
[0020] (Connection structure between upper body 11 and lower body 12) The upper body section 11 and the lower body section 12 are overlapped in the vertical direction of the axis 20 with their central axes aligned, and are joined by, for example, screwing. Alternatively, the upper body section 11 and the lower body section 12 are butted together in the axial direction at a first relative rotation position about the axis 20, and are then rotated relative to each other to a second relative rotation position about the axis 20, whereby the lower surface of a joining piece (not shown) of the lower body section 12 and the upper surface of a joining piece (not shown) of the upper body section 11 come into contact and are joined together.
[0021] <Axis 20> FIG. 6 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.
[0022] 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 circumferentially by partitions, and the above-mentioned claws 14e can fit into the divided recesses. When the recesses of this constricted portion 26 fit into the claws 14e, the claws 14e engage with the constricted portion 26, and the shaft 20 is clamped by the claws 14e. The lower surface of the constricted portion 26 forms an inclined surface 26a that slopes downward radially outward (see FIG. 6). This inclined surface 26a constitutes a second sliding contact portion.
[0023] The shaft 20 is movable in the axial direction between a first position where it is clamped by the claws 14e and a second position where 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 comes into sliding contact with the claws 14e. In other words, the lower surface of the claws 14e is an inclined surface, which constitutes a first sliding contact portion that comes into sliding contact with the second sliding contact portion. According to this structure, when the shaft 20 moves within the shaft hole 13a to the second position due to the impact of landing, the claw 14e is elastically deformed and stored by sliding against the inclined surface 26a, and when the impact of landing stops, the stored elastic force causes the shaft 20 to move to the first position by sliding against the inclined surface 26a.
[0024] A large flange 27 is formed below constricted portion 26. Large flange 27 constitutes part of protruding portion 20B. When shaft 20 is in a first position where it is clamped by claws 14e, large flange 27 is spaced apart from the underside of lower trunk 12. When shaft 20 is in a second position where it is deeply inserted into shaft hole 13a, large flange 27 abuts against the underside of lower trunk 12. 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. 6, the portion indicated by the reference numeral 20a is a ridge that engages with a fixed portion inside the toy top 100 and has a rotation-preventing function. This ridge may be omitted.
[0025] (Axis 20 operation) FIG. 7 is a diagram showing how the shaft 20 and the shaft locking member 14 change when the spinning top 100 lands, and FIG. 8 is a diagram showing how the spinning top 100 changes when the spinning top 100 lands. Before landing, the constricted portion 26 and the claw 14e are engaged (FIG. 7(A)), and the shaft 20 is in a state of protruding downward from the lower trunk portion 12 (FIG. 8(A)). When the impact of landing causes the shaft 20 to move from this state toward the second position, 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 (FIG. 7(B)). This movement of the shaft 20 causes the shaft 20 to be pushed into the lower body 12, so that the large flange 27 abuts against the underside of the lower body 12 (FIG. 8(B)). Thereafter, when the impact of landing subsides, the stored elastic force of claw 14e causes elastic locking portion 14c to move in a direction to release the deflection, and the sliding contact between the second sliding contact portion of constricted portion 26 and the first sliding contact portion of claw 14e pushes shaft 20 back to the first position (FIG. 7(C)). This movement of shaft 20 causes shaft 20 to return to the state in which it protrudes downward from lower trunk 12 (FIG. 8(C)).
[0026] According to the above-described shaft structure and shaft locking structure, when the shaft 20 is pushed into the shaft hole 13a by the impact of landing, the elastic locking portion 14c elastically deforms, thereby absorbing the impact energy and preventing as much as possible the bouncing of the toy top 100. As a result, the loss of rotational energy can be reduced, and the toy top 100 can be landed at a desired position on the floor.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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 having an opening in the center. A guide portion 93 is provided in the field 91, and has teeth 93a formed thereon to 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. <<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.
[0032] For example, in the above embodiment, the lower surface of the constricted portion 26 is formed as an inclined surface (sliding contact portion) 26a that slopes downward radially outward, but the inclined surface (sliding contact portion) may extend to the lower portion of the insertion portion 20A. 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 during movement.
[0033] 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 radially reciprocatable and radially inwardly biased by a coil spring. [Explanation of symbols]
