Description

[Technical Field]

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

[0002] Conventionally, a toy top play table has been known that includes multiple turntables arranged on the play surface for spinning toy tops, and a drive device that rotates the turntables using the power of a motor (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-171679 Summary of the Invention [Problem to be solved by the invention]

[0004] In the invention described in the above Patent Document 1, the toy top runs around in various directions as the turntable rotates. However, if we focus on one toy top, the toy top steps onto the turntable from the outside, and then jumps out of the turntable in a similar trajectory, although the direction of the jump varies. This is a repetition of the process, so the movement is monotonous. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a stadium toy that allows a toy top to run around in a variety of ways. [Means for solving the problem]

[0005] The first method is A stadium toy having a field with a floor on which a rotationally biased toy top runs, a movable part that is configured to be movable and that, by its movement, causes a step part to appear and disappear, which limits the range in which the toy top runs around; and a retraction mechanism that operates the movable part to make the step part retract.

[0006] The second means is the first means, characterized in that the movable part constitutes a part of the floor, is configured to be able to rise and fall relative to the rest of the floor, and creates the step between it and the rest of the floor in response to the rising and falling.

[0007] A third aspect is the second aspect, characterized in that the movable part is circular in plan view.

[0008] A fourth means is the second or third means, characterized in that the movable part is provided in the center of the floor.

[0009] The fifth means is the second or third means, characterized in that the step portion is provided with an acceleration rail that engages with a wheel attached to the top toy to accelerate the speed at which the top toy runs, and the acceleration rail appears and disappears along with the step portion.

[0010] A sixth aspect of the present invention is the fifth aspect, characterized in that the acceleration rail extends around the entire periphery of the step portion.

[0011] The seventh means is the fifth means, characterized in that the retraction mechanism uses a motor as a power source, and when the alternate operation switch is turned on, the motor power continues to move the movable floor up and down.

[0012] The eighth means is the seventh means, characterized in that the retraction mechanism makes the floor of the movable part flush with the rest of the floor when the operation switch is turned off.

[0013] A ninth means is any one of the first to third means, characterized in that another fixed acceleration rail is provided on the outer edge of the floor. [Effects of the Invention]

[0014] According to the present invention, the step portion appears and disappears, so that the toy top can be made to run in the direction in which the step portion extends, and when the step is eliminated, the toy top can be made to run across that area. [Brief explanation of the drawings]

[0016] FIG. 1 is a perspective view of the stadium toy 10, FIG. 2 is a perspective view of the stadium toy 10 seen from below, and FIG. 3 is a perspective view of the stadium toy 10 with the cover 16 removed and the movable floor 13a lowered. The toy stadium 10 is used to make two or more rotationally biased toy tops 50 battle each other. According to this toy stadium 10, a toy top 50 released onto the field 11 runs around the field 11 and collides with other toy tops 50, resulting in a battle between the toy tops 50. During this battle, when the toy top 50 collides with an acceleration rail 12 that defines the field 11, the movement of the toy top 50 is accelerated. Furthermore, part of the floor 13 of the field 11 is a movable floor 13a (Fig. 3). When switch SW1 (Fig. 2) is turned on, the movable floor 13a continues to move up and down. When the movable floor 13a descends, a recess is formed in the floor surface, and a step appears between the movable floor 13a and the surrounding floor 13b. Then, the acceleration rail 14 formed in the step becomes exposed. When the running toy top 50 falls into the recess, the toy top 50 runs around inside the recess. Then, when the toy top 50 touches the acceleration rail 14, it accelerates and runs around vigorously along the acceleration rail 14. During this time, the movable floor 13a continues to move up and down. Eventually, when the movable floor 13a becomes flush with the surrounding floor 13b, the momentum of the toy top 50 moves out onto the surrounding surrounding floor 13b due to the centrifugal force of its movement. Then, the toy top 50 hits the acceleration rail 12 and is accelerated.

[0017] (50 spinning tops) FIG. 4 is a perspective view of the toy top 50. As shown in FIG. The toy top 50 has a body 51 and an axle 52. The body 51 and the axle 52 rotate together, although this is not a particular limitation. A wheel 53 is provided on the axle 52. In this embodiment, the wheel 53 is a gear. The wheel 53 engages with the functional parts of the acceleration rails 12, 14 as the toy top 50 runs. As a result, the wheel 53 rolls while abutting against the acceleration rails 12, 14, and the toy top 50 accelerates. The rotation of the toy top 50 is achieved by inserting the forks of a launching device (not shown) into the arc-shaped recesses 54, 54 formed on the top surface of the body 51, and rotating the toy top 50 relative to the forks in the direction opposite to the rotational biasing direction of the toy top 50, so that the toy top 50 is locked by the forks, and in this state, the launching toy rotates the forks in the rotational biasing direction. When the forks then stop rotating, the toy top 50 is released from the launching toy.

[0018] (Stadium Toy 10) FIG. 5 is an exploded perspective view of the toy stadium 10. As shown in FIG. The toy stadium 10 includes a base board 15 that forms a field 11 and a cover 16 that is placed on the base board 15. The base board 15 is made of transparent plastic and is supported by four legs 17 so that the floor 13 of the field 11 is at a predetermined height. The cover 16 is made of transparent plastic and has a circular opening in the center of the ceiling through which a rotationally biased toy top 50 can be inserted. The cover 16 is attached to the base board 15 by fitting parts of the four fasteners 18 into the four legs 17 through holes (not shown) in the cover 16 and base board 15 .

[0019] The floor 13 of the field 11 of the base board 15 is a bowl-shaped recess as a whole. The center of the floor 13 is a movable floor 13a, and fixed peripheral floors 13b are arranged on the outside of it. In addition, the toy stadium 10 is arranged with acceleration rails 12 so as to divide the field 11. The acceleration rails 12 are made up of rack members arranged in a heart shape when viewed from above.

[0020] FIG. 6 is an exploded perspective view of the base board 15 and the operation unit 20 of the stadium toy 10, and FIG. The toy stadium 10 includes an operating unit 20 that moves the movable floor 13a up and down. The operating unit 20 includes a cylindrical bolt-and-bolt case 21. A circular seat plate 22 is provided at the upper edge of the case 21. An acceleration rail 14 that is circular in top view and a connecting floor 13c that is circular in top view and forms part of the peripheral floor 13b are placed on the seat plate 22. The floor 13c is fitted onto the acceleration rail 14 from below, and is fixed to the case 21 by inserting a female-threaded boss 130c of the floor 13c into a hole 22a in the seat plate 22 and threading a male screw (not shown) into the female thread of the boss 130c from the underside of the case 21.

[0021] FIG. 8 is a perspective view showing the internal structure of the case 21. As shown in FIG. A movable floor 13a, which is circular in top view, is attached to the case 21 so as to close the upper end opening of the case 21. The movable floor 13a is supported by the case 21 so as to be able to move up and down, and is biased downward by a coil spring 130a. The movable floor 13a is disposed inside an acceleration rail 14, which is circular in top view. A drive device 23 for moving the movable floor 13a up and down is disposed below the movable floor 13a.

[0022] FIG. 9 is a perspective view showing the drive device 23, and FIG. 10 is a perspective view showing the drive device 23 as seen from a different angle. The drive device 23 includes a motor 24 as a power source, a plate cam 25 with the movable floor 13a as a follower, and a power transmission mechanism 26 that transmits motor power to the plate cam 25. The plate cam 25 constitutes a retraction mechanism that retracts the step portion. A notch 25a is formed in the end face of the plate cam 25. An operating part of a switch SW2 (described later) can be brought into contact with or separated from the end face of the plate cam 25 depending on the rotation position. That is, as the plate cam 25 rotates, the operating part of the switch SW2 moves away from the end face of the plate cam 25 at the position of the notch 25a and comes into contact with the end face of the plate cam 25 at a location other than the notch 25a. The power transmission mechanism 26 transmits motor power to the plate cam 25 via gears 26a to 26h. A clutch (torque limiter) 26i is provided between gears 26e and 26f, and cuts off the power transmission therebetween when an overload occurs. The plate cam 25 is an eccentric rotating body. This plate cam 25 and the movable bed 13a, which is biased by the coil spring 130a, form a positive motion cam. Here, the plate cam 25 abuts against the lower surface of the center of the movable bed 13a. As a result, when the plate cam 25 rotates, the movable bed 13a moves up and down.

[0023] A battery box 27 is provided inside the case 21, and a battery can be attached and detached to the battery box 27 by opening a cover 28 (FIG. 2) on the bottom side of the case 21.

[0024] (Circuit configuration) FIG. 11 shows the motor drive circuit 40 of the stadium toy 10. In the motor drive circuit 40, a switch SW1 and a switch SW2 are arranged in parallel with the motor 24. The switch SW1 is an alternate switch for power supply, and when the switch SW1 is turned on, the motor 24 is operated and the plate cam 25 rotates. The switch SW2 is a momentary switch and is disposed close to the plate cam 25. The switch SW2 is capable of contacting and separating from the end face of the plate cam 25.

[0025] According to this motor drive circuit 40, when switch SW1 is turned ON, the motor 24 is operated regardless of the state of switch SW2, causing the plate cam 25 to rotate. Furthermore, if switch SW1 is turned OFF in this state, switch SW2 is ON while the operating portion of switch SW2 is in contact with the end face of plate cam 25, causing the motor 24 to continue rotating. Then, as plate cam 25 rotates, when notch 25a on the end face of plate cam 25 reaches the operating portion of switch SW2, switch SW2 is turned OFF and the rotation of motor 24 stops; this position is where the movable floor 13a and the peripheral floor 13b are flush with each other.

[0026] (How to play and actions, etc.) Next, a method of playing with the stadium toy 10 and the operation of the stadium toy 10 will be described. Fig. 12 is a perspective view of the operation unit 20 showing a state in which the movable floor 13a is flush with the surrounding floor 13b, and Fig. 13 is a perspective view of the operation unit 20 showing a state in which the movable floor 13a is lowered relative to the surrounding floor 13b. When the switch SW1 is in the OFF state, the movable floor 13a is flush with the surrounding floor 13b. When two or more rotationally biased toy tops 50 are released into the toy stadium 10 in this state, the toy tops 50 collide with each other, allowing a battle to take place. In this case, when the toy tops 50 come into contact with the acceleration rails 12, they are accelerated by the acceleration rails 12, and a battle begins.

[0027] Furthermore, when switch SW1 is turned ON, motor 24 is activated, plate cam 25 rotates, and movable floor 13a repeatedly moves up and down until switch SW1 is turned OFF. When movable floor 13a descends, a recess is formed in floor 13. Because peripheral floor 13b is inclined, spinning toy top 50 easily falls into the recess. When the toy top 50 falls into the recess, the toy top 50 is restrained in the recess, and the wheels 53 of the toy top 50 running around in the recess immediately engage with the functional parts of the acceleration rail 14. This causes the toy top 50 to accelerate and move around along the acceleration rail 14. Then, when the movable floor 13a moves up and becomes flush with the surrounding floor 13b, the centrifugal force causes the toy top 50 to fly out of the movable floor 13a with force and hit the outer acceleration rail 12, where it is also accelerated, and the battle begins. The above operation is repeated until the toy top 50 stops or loses momentum.

[0028] Also, when the switch SW1 is turned OFF in this state, the plate cam 25 rotates until the switch SW2 is turned OFF, and the movable floor 13a moves up until it becomes flush with the peripheral floor 13b, at which point the movable floor 13a stops.

[0029] (Effects of the embodiment) The stadium toy 10 of this embodiment can provide the following effects. By moving the movable floor (adjacent part) 13a up and down relative to at least some of the functional parts (teeth) of the acceleration rail 14, the acceleration of the toy top 50 in that area changes, so a highly entertaining stadium toy 10 can be realized. Furthermore, since the movable floor 13a is moved up and down, the range in which the toy top 50 can run can be changed in accordance with the up and down movement of the movable floor 13a, thereby realizing a highly entertaining toy stadium 10. In addition, when the movable floor 13a descends, a recess is formed in the floor 13 of the field 11, and the toy top 50 that falls into the recess can be accelerated by the acceleration rail 14. Furthermore, by turning on switch SW1, the motor power can be used to easily continue the up and down movement, so the acceleration region and running region of the toy top can be changed over time. Furthermore, when switch SW1 is turned off, the floor surface returns to its initial state, so that play can be easily resumed in the initial state at any time. Furthermore, since the acceleration region can be increased, the toy top 50 can be made to run around more vigorously. In addition, an acceleration rail 14 is provided around the entire circumference of the circular stepped portion when viewed from above, so that the accelerated toy top 50 moves around along the acceleration rail 14 and moves out from the movable floor 13a when the movable floor 13a and the surrounding floor 13b become flush with each other, which also makes it possible to give randomness to the movement of the toy top 50.

[0030] (Variation) Although the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment and various modifications are possible.

[0031] For example, in the above embodiment, the acceleration rail 14 is provided at the step portion, but it is not necessary to provide the acceleration rail 14. When a step portion appears, the range of movement of the toy top 50 is restricted, and when the step portion is eliminated, the toy top 50 moves around, crossing the area where the step was.

[0032] In addition, in the above embodiment, the movable floor 13 a is provided in the center of the field 11 , but the movable floor 13 a may be provided at the end of the field 11 .

[0033] In addition, in the above embodiment, the functional portion of the acceleration rail 14 is provided around the entire periphery of the step portion formed when the movable floor 13a is lowered, but the functional portion of the acceleration rail 14 may also be provided on only a part of the step portion.

[0034] Furthermore, in the above embodiment, the movable floor 13a (adjacent portion) adjacent to the functional portion (tooth) of the acceleration rail 14 is movable up and down, but the adjacent portion may move along the floor surface to move toward and away from the functional portion (tooth) of the acceleration rail 14. In this case, when the functional portion of the acceleration rail 14 and the adjacent portion move away from each other, a passage for the toy top 50 is formed between the functional portion and the adjacent portion of the acceleration rail 14. Furthermore, the movable floor 13a does not have to be moved up and down as a whole, and may be rotated up and down around a predetermined axis.

[0035] Furthermore, in the above embodiment, the movable floor 13a is moved up and down by the plate cam 25, but the movable floor 13a may also be moved up and down by expanding and contracting a bellows that can supply and exhaust air using an actuator, or by using a rack and pinion, lever, or link mechanism.

[0036] In the above embodiment, the movable floor 13a is configured to move up and down relative to the acceleration rails 14, but the movable floor 13a may be a fixed floor and the acceleration rails 14 may be configured to move up and down.

[0037] Furthermore, in the above embodiment, the movable floor 13a is moved up and down by motor power, but it may also be moved up and down by manual operation. In this case, it is necessary to provide an operating switch in a position where it can be operated while playing.

[0038] Furthermore, in the above embodiment, the movable floor 13a is configured to move up and down continuously, but it may be configured so that it can be stopped at predetermined positions in stages.

[0039] Furthermore, in the above embodiment, the movable floor 13a is configured to move up and down continuously, but it may also be configured to move up and down intermittently, or it may be configured to change the speed of the up and down movement while the up and down movement is continuing.

[0040] Also, although switch SW1 is an alternate switch, it may be configured as a momentary switch that moves up and down only while the switch is being operated. In this case, the operating switch must be located in a position where it can be operated while playing.

[0041] In the above embodiment, the wheels 53 of the toy top 50 are gears, but they may be rollers that roll on the acceleration rails. In this case, the acceleration rails 12, 14 do not need to have teeth. The key is that the rollers roll while abutting against the functional parts of the acceleration rails.

[0042] In addition, in the above embodiment, the movable floor 13a is circular when viewed from above, but the shape is not limited thereto.

[0043] In addition, the movable part that limits the movement of the toy top 50 may be one that moves up and down, or one that slides / rotates from the side without forming a floor surface, or one that drops from above by rotating on an axis.

[0044] The sliding surface of the movable part that comes into contact with the toy top may be straight, but it is preferable that it be curved in top view so as to apply centrifugal force to the toy top and increase its rotational force.

[0045] Although the modifications of the present invention have been described above, it goes without saying that the modifications can be combined as appropriate as long as no contradiction occurs. [Explanation of symbols]
