Spinning top game board

Abstract

To provide a spinning top game board that allows spinning tops to move around not only on a flat surface but also in a three-dimensional space. [Solution] A spinning top game board 10 is provided with a floor 12a on which a spinning top 50, which has a gear 53 attached to an axle 52, is rotated and released for play. The board is characterized by having a slope 14 on which the spinning top 50 ascends, and a rack 15 which causes the spinning top 50 to run up the slope 14 through meshing with the gear 53 as the spinning top 50 runs around. As a result, the movement of the spinning top is accelerated by the rotational force of the top itself and it runs up the slope, so the range in which the spinning top can move becomes three-dimensional (three-dimensional), making it possible to realize a highly entertaining spinning top game board.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the above-mentioned top toy board only accelerates the top within the floor where the top runs around, and the running range is limited. The present invention has been made in view of such circumstances, and an object thereof is to provide a top toy board that can make the top run around not only flatly but also three-dimensionally.

Means for Solving the Problems

[0005] The first means is a top toy board in which a floor is formed for playing by rotationally biasing and releasing a top with a gear attached to a shaft, wherein a slope for the top to climb and a rack for driving the top up the slope by meshing with the gear due to the rotation of the top are provided, and the top toy board is characterized by this.

[0006] The second means is the first means, characterized in that the slope is configured to become higher as it approaches the end.

[0007] The third means is the first means, characterized in that a cliff is formed at the top of the slope, and the top that has come up the slope falls from the cliff onto the floor.

[0008] The fourth means is the first means, characterized in that each tooth of the rack extends in the vertical direction.

[0009] The fifth means is the third means, characterized in that a passage is formed on the slope of the ramp that slides against the outer circumference of the shaft end of the ascending top or the outer circumference of the gear, guiding the top to the cliff.

[0010] The sixth means is characterized in that the road surface of the slope is an inclined surface with a downward slope toward the cliff between the rack and the cliff at the end of the slope.

[0011] The seventh means is any of the first to sixth means, The aforementioned floor has a step formed in the shape of an arc, with a portion of its circumference open when viewed from above. The aforementioned step has a height that allows the outer circumference of the shaft end of the spinning top or the outer circumference of the gear to come into contact with it. The spinning top is accelerated by sliding contact between the outer circumference of the shaft end or the outer circumference of the gear and the step, and the accelerated top is released toward the slope.

[0012] The eighth means is the seventh means, Within the area demarcated by the aforementioned step, another step is formed that extends in an arc shape with a portion of its circumference open when viewed from above. The aforementioned other steps have a height that allows the outer circumference of the tip of the spinning top to come into contact with them. The spinning top is accelerated by sliding contact between the outer circumference of the shaft end or the outer circumference of the gear and the other step, and the accelerated top is released toward the first step.

[0013] The ninth means is the first means, The spinning top game board comprises a base that is rectangular in shape when viewed from above and on which the floor is formed, and a cover that is detachably attached to the base and covers the outer periphery of the floor. The cover is configured to be attachable to the base from above, with its horizontal orientation differing between the use state and the storage state. The base is formed with a first contact portion used in the operating state and a second contact portion used in the stored state. The cover is formed with a third contact portion that contacts the first contact portion when in use, and a fourth contact portion that contacts the second contact portion when stored. The base and the cover are configured such that the height from the bottom surface of the base to the top edge of the cover in the stored state is lower than the height from the bottom surface of the base to the top edge of the cover in the used state. [Effects of the Invention]

[0014] According to the present invention, the gears and rack mesh together, accelerating the movement of the spinning top due to its own rotational force, causing it to run up the slope. This results in a three-dimensional (three-dimensional) range of movement for the spinning top, making it possible to create a highly engaging spinning top game board.

Mode for Carrying Out the Invention

[0016] Hereinafter, the piece game board according to the embodiment of the present invention will be described based on the drawings.

[0017] FIG. 1 is a perspective view showing the piece game board 10 and the pieces 50. The piece game board 10 is used, for example, for battles between pieces 50. In the battle, for example, each of two players sets their own piece 50 on the launcher, rotationally biases it with the launcher, and releases it from the field of the piece game board 10. Then, the pieces 50 collide with each other on the field.

[0018] (Piece 50) The piece 50 is configured to include a body portion 51 and a shaft 52. The body portion 51 is composed of, for example, a plurality of separable layers, and the plurality of layers can be separated by a collision with another piece 50. When the pieces 50 collide with each other, depending on the position of the collision, an impact that relatively rotates at least one of the plurality of layers of the body portion 51 in a direction opposite to the rotational direction of the piece 50 acts, causing the plurality of layers to be separated. The shaft 52 is rod-shaped, and the tip of the shaft is formed flat. The tip of the shaft may be pointed, but a flat shape makes it easier to run around the field. Also, a gear 53 is fixed to the shaft 52 of the piece 50 at a predetermined height position from the tip of the shaft. The gear 53 meshes with a rack 15 described later as the piece 50 runs around. When the gear 53 meshes with the rack 15 and the gear 53 rolls on the rack 15 by the rotational force of the piece 50, the running speed of the piece 50 increases.

[0019] (Piece game board 10) Figure 2 is an exploded perspective view of the spinning top game board 10, and Figure 3 is a top view of the spinning top game board 10. The spinning top game board 10 is broadly composed of a base 12 that forms the field and a cover 13 that covers the perimeter and top of the field to prevent the spinning tops 50 from flying off the field. The base 12 is broadly composed of a floor 12a that serves as the main battlefield during battles and a slope 14 for raising the spinning tops 50 from the floor 12a.

[0020] A. Slope 14 The slope 14 is formed along the edge of the field when viewed from above. The slope 14 is configured to become higher as it approaches the end, for example. In other words, it is preferable that the slope 14 has an upward gradient from the start to the end (monotonically increasing). However, there may be flat sections or downhill sections along the slope 14. The spinning top game board 10 according to this embodiment has two slopes 14 so that it can accommodate not only spinning tops 50 that rotate clockwise when viewed from above, but also spinning tops 50 that rotate counterclockwise when viewed from above. Since these two slopes 14 have a mirror-symmetric structure, only one will be described, and the description of the other will be omitted.

[0021] On the outer side of the slope 14 in the width direction, a rack 15 is formed along the slope 14. The rack 15 meshes with the gear 53 of the spinning top 50 that runs around on the floor 12a, causing the spinning top 50 to run up the slope 14. A cliff 16 is formed at the top of the slope 14. As a result, the spinning top 50 that reach the top of the slope 14 fall from the cliff 16 to the floor 12a and attack other spinning tops 50 on the floor 12a from above. Furthermore, the racks 15 corresponding to each of the two slopes 14 extend in an arc along the edge of the circular floor 12a at the bottom of the slope and are connected to each other.

[0022] B. Floor 12a Floor 12a is bowl-shaped and has a circular shape when viewed from above. Two steps 17a and 17b are formed within floor 12a. For example, steps 17a and 17b are made up of walls that extend vertically so that the inside is lower, and when viewed from above, they extend in an arc shape (C shape) with a part of the circumference open.

[0023] The radius of step 17a is larger than that of step 17b. When viewed from above, step 17a is formed at a position offset from the center of floor 12a towards the downhill side of slope 14, and its circumference is open towards the downhill side. At this open circumference, the floor portion enclosed by step 17a is connected to the floor portion outside of step 17a. Furthermore, the area enclosed by the step 17a is large enough for the piece 50 to run around in.

[0024] Step 17b is formed in the center of the area demarcated by step 17a. When viewed from above, step 17b has an open circumference towards the uphill side. At the open circumference, the floor area enclosed by step 17b is connected to the floor area outside step 17b. Furthermore, the area enclosed by the step 17b is large enough for the piece 50 to run around in.

[0025] Preferably, the steps 17a and 17b are high enough to allow the outer circumference of the shaft end below the gear 53 of the top 50 to come into contact with them. As the top 50 moves around, the outer circumference of the shaft end comes into sliding contact with the steps 17a and 17b, increasing the speed at which the top 50 moves around. For example, a top 50 moving around within step 17b will increase its speed as the outer circumference of the shaft end comes into sliding contact with step 17b, and will move out of step 17b. Then, the outer circumference of the shaft end of the top 50 will come into sliding contact with step 17a, further increasing its speed, and it will be released towards the slope 14. In this way, the top 50 is transferred to the slope 14 with momentum, making it easier for the top 50 to climb the slope 14. Alternatively, the shaft end of the top 50 may not extend below the gear 53, and the outer circumference of the gear 53 may come into direct contact with the steps 17a and 17b.

[0026] C. Structure of the slope at the top of slope 14 Figure 4 is a partial perspective view of the slope 14 and an enlarged view of the top of the slope. At the top of each slope 14, a passage 18a is formed that directs the path of the spinning top 50 coming up the slope 14 toward the cliff 16. Unlike the rack 15, the outer wall of the passage 18a does not have teeth. This is because the passage 18a makes a sharp curve relative to the slope 14, and if teeth similar to those of the rack 15 were to be provided there, the gear 53 of the spinning top 50 would be deflected by those teeth. The outer circumference of the shaft end of the spinning top 50 or the outer circumference of the gear 53 slides against the outer wall of this passage 18a. This guides the spinning top toy 50 to the cliff 16.

[0027] D. Inclined surfaces 19a, 19b On the inner side of the end of each slope 14, an inclined surface 19a with a downward slope toward the cliff 16 is formed, and on the slope 14 side of the passage 18a at the top of each slope, an inclined surface 19b with a downward slope is formed, which is connected to the inclined surface 19a. Each inclined surface 19a drops the top 50 onto the floor 12a if the top 50 loses momentum while climbing the slope 14 and cannot reach the top of the slope. Each inclined surface 19b guides the top 50 onto the inclined surface 19a if the top 50 loses momentum after reaching the top of the slope and cannot reach the cliff 16.

[0028] (Mounting structure of cover 13) Figure 5 shows an exploded perspective view of the spinning top game board 10 in use and an exploded perspective view of the spinning top game board 10 when stored. The cover 13 covers the base 12 and has a circular opening 13a in the center. The cover 13 is configured to be detachable from the base 12 and is attached to the base 12 in a different orientation when in use and when stored. In the following description of the base 12 and the cover 13, front and rear and left and right refer to the front and rear and left and right indicated by the arrows in Figure 5.

[0029] When in use, the cover 13 is attached to the base 12 in the orientation shown in Figure 5 and secured to the base 12 by fasteners 24 (Figures 8 and 9). On the other hand, when stored, the cover 13 is mounted on the base 12 in the orientation shown in Figure 6, which is a left-right reversal from the orientation shown in Figure 5. In the stored state, the cover 13 is deeply fitted into the base 12 (Figure 7). As a result, when stored, the height from the bottom surface of the base 12 to the top edge of the cover 13 can be made lower than when in use.

[0030] Specifically, the base 12 is provided with a rectangular enclosure 20 that, when viewed from above, demarcates the field. The enclosure 20 bulges upwards and is hollow at the bottom. When viewed from above, the left and right edges of the enclosure 20 are undulating along the front-to-back direction.

[0031] The left side of the base 12 has upward-facing protrusions 21a and 21b at the front-to-back corners of the base 12, and an upward-facing recess 21c at the center of the base 12 in the front-to-back direction. Furthermore, the undulating portion on the right side has upward-facing concave portions 21d and 21e at the front and rear corners of the base 12, and an upward-facing convex portion 21f at the center of the base 12 in the front-to-back direction. Furthermore, first contact portions 22a, 22b, and 22f are formed on the upward-facing protrusions 21a, 21b, and 21f, respectively. The first contact portions 22a, 22b, and 22f are formed at the same height from the bottom surface of the base 12. When in use, the third contact portion of the cover 13, which will be described later, comes into contact with the first contact portions 22a, 22b, and 22f. In addition, rectangular holes are formed in the first contact portions 22a, 22b, and 22f for attaching fasteners 24, which will be described later. Furthermore, a protruding portion (second contact portion) 22g is formed at the bottom of the base 12, extending horizontally outward. When stored, the protruding portion (fourth contact portion) 25g of the cover 13, which will be described later, comes into contact with the second contact portion 22g.

[0032] On the other hand, cover 13 bulges upwards and has a hollow lower side. When viewed from below, the upper wall of cover 13 has undulations along the front-to-back direction on both the left and right edges. The left side of the cover 13 has downward-facing protrusions 25a and 25b at the front-to-back corners of its upper wall, and a downward-facing recess 25c at the center of its upper wall. Furthermore, the right-side undulating portion of the cover 13 has downward-facing recesses 25d and 25e at the front-to-back corners of its upper wall, and a downward-facing convex portion 25f at the center of its upper wall in the front-to-back direction. Furthermore, a third contact portion (not shown) is formed on the lower surface of each of the downward-facing protrusions 25a, 25b, and 25f. The third contact portion is formed at the same height from the bottom surface of the cover 13. When in use, the third contact portion comes into contact with the upper surface of the first contact portions 22a, 22b, and 22f. A rectangular hole for attaching a fastener 24 is formed in the third contact portion. Furthermore, an outwardly protruding portion (fourth contact portion) 25g is formed at the lower end of the cover 13. When stored, the protruding portion (fourth contact portion) 25g comes into contact with the protruding portion (second contact portion) 22g of the base 12 described above.

[0033] (Fastener 24) Figure 8 is a perspective view of the fastener 24, and Figure 9 is a front view of the fastener 24. The fastener 24 secures the cover 13 to the base 12 when in use, with the lower surface of the third contact portion of the cover 13 in contact with the upper surface of the first contact portions 22a, 22b, and 22f of the base 12. At this time, the rectangular hole of the third contact portion and the rectangular holes of the first contact portions 22a, 22b, and 22f are abutted together.

[0034] The fastener 24 consists of a contact plate 24a that contacts the upper surface of the third contact portion of the cover 13, and a pair of elastic locking claws 24b, 24b formed on the lower surface of the contact plate 24a and inserted into the rectangular holes of the third contact portion and the rectangular holes of the first contact portions 22a, 22b, 22f. Each elastic locking claw 24b has an inclined portion 24c formed thereon. When a pair of elastic locking claws 24b, 24b are inserted into the rectangular holes of the third contact portion and the first contact portions 22a, 22b, 22f, they slide against the edge of the rectangular hole of the third contact portion, causing them to narrow in a direction that brings them closer together. Then, when the pair of elastic locking claws 24b, 24b are fully inserted into the rectangular holes of the third contact portion and the rectangular holes of the first contact portions 22a, 22b, 22f, the elastic force of the pair of elastic locking claws 24b, 24b engages with the lower edges of the rectangular holes of the first contact portions 22a, 22b, 22f.

[0035] (Effects of the embodiment) According to the spinning top game board 10 configured as described above, the following effects can be obtained.

[0036] Firstly, the field is provided with a slope 14 on which the top 50 ascends, and a rack 15 that allows the top 50 to run up the slope 14 through the meshing of the gear 53 caused by the top 50's movement. Therefore, the top 50 can not only move along the floor 12a, but also run up the slope 14 by its own rotational force.

[0037] Secondly, a cliff 16 is formed at the top of the slope 14, and the piece 50 is configured to fall from the cliff 16 to the floor 12a, allowing the piece 50 to move three-dimensionally within the field. In addition, this increases the range of attacks, such as attacking from above during battle.

[0038] Thirdly, since each tooth of the rack 15 extends vertically, the gear 53 of the saddle 50 can easily mesh with the rack 15 without being repelled, allowing the saddle 50 to run up the slope 14 reliably.

[0039] Fourth, a passage 18a is formed at the top of the slope 14 that slides against the shaft 52 of the ascending piece 50 and guides the piece 50 to the cliff 16, so that the piece 50 is guided smoothly to the cliff 16 without being bounced away.

[0040] Fifth, at the end of the slope 14, the road surface is an inclined surface 19a with a downward slope toward the cliff 16. Therefore, if the momentum of the car 50 going up the slope 14 is lost and it cannot reach the top of the slope, the car 50 can be dropped onto the floor 12a.

[0041] Sixth, since a step 17a extending in a C-shape when viewed from above is formed on the floor 12a, the outer circumference of the shaft end of the top 50 slides against the step 17a, causing the top 50 to accelerate and be released toward the slope 14, making it easier for the top 50 to climb the slope 14.

[0042] Seventh, since the floor 12a has a step 17b that extends in a C-shape when viewed from above, in addition to the step 17a, the car 50 is accelerated in two stages, making it even easier for the car 50 to climb the slope 14.

[0043] Eighth, by changing the orientation of the cover 13 when using and storing it and attaching it to the base 12, the height from the bottom surface of the base 12 to the top edge of the cover 13 can be reduced when stored, making it easier to handle the spinning top game board 10 when shipping and storing the product.

[0044] (modified version) Although the spinning top game board 10 according to the embodiment has been described above, it goes without saying that the present invention is not limited to the above embodiment and various modifications are possible.

[0045] For example, in the above embodiment, a passageway 18a is connected to the upper end of the slope 14, but a cliff 16 may also be provided at the upper end of the slope 14.

[0046] Furthermore, the steps 17a and 17b in the above embodiment may or may not be provided with racks similar to the rack 15 that mesh with the gear 53. [Explanation of Symbols]
