Description

[Detailed Description of the Invention] The present invention relates to a small-sized amusement vehicle that is installed on the rooftops or game corners of amusement parks, department stores, etc., and is mainly aimed at children such as infants.

This type of small-sized amusement vehicle is used to entertain about two children and the like by operating it for a certain period of time by inserting a coin.

However, the movement of conventional small-sized amusement vehicles is simple, with the vehicle body on which the player rides simply moving up and down, rotating in a horizontal plane, or rocking. For this reason, there was a need to develop small amusement vehicles that had interesting movements.

Therefore, in order to easily satisfy the playful spirit of children, the inventor of the present invention devised and prototyped a small amusement vehicle in which the vehicle body moves in a circular motion along a vertical plane. This prototype machine has a structure in which the vehicle body is supported by a parallel crank mechanism, and the opposing rotating cranks of the parallel crank mechanism are rotated by a drive device.The drive device uses multiple belt transmissions to reduce the rotation of the motor. However, the deceleration output was transmitted to the rotating crank via a chain transmission mechanism.

By the way, according to this prototype machine, it is inevitable that the magnitude of the load acting on the rotating crank of the parallel crank mechanism is considerably different when the vehicle body is ascending and descending. Therefore, when the vehicle body rises, the chain is stretched more strongly, so that the circular movement of the vehicle body becomes unsmooth, and
It has been found that when one of the multiple chains is stretched, the phase of the driven sprocket wheel axis shifts, making the movement of the parallel crank mechanism unnatural and likely to cause discomfort to the player. In addition, since the mechanical system receives a large impact due to the unsmooth movement of the vehicle body, the life of the mechanical system is likely to be shortened. Furthermore, it is thought that the chain is likely to break due to repeated fluctuations in its tension, but if the vehicle body is above the bottom dead center position (lowest position) when the chain is cut or the motor is stopped, the chain will break. There is a risk of falling and there is a risk of lack of safety.

For this reason, it was found that the above prototype was not suitable for practical use.

Therefore, the purpose of the present invention is to provide a practical amusement vehicle that not only satisfies the playful spirit of children and other players, but also improves the riding comfort of the players, has a long lifespan, and is excellent in safety. Our goal is to provide the following.

That is, the present invention includes a motor, a worm reducer connected to the rotating shaft of the motor to reduce the rotation of the motor, a drive gear connected to the output shaft of the reducer, and a drive gear connected to the drive gear. A driving device having a pair of meshed left and right driven gears is attached, and rotary cranks that are rotated in parallel to each other are fixed to each gear shaft of the pair of driven gears, and are linked to the pair of rotary cranks. span to form a parallel crank mechanism,
This game vehicle is characterized in that a vehicle body on which a player rides is attached to the link.

According to the amusement vehicle of the present invention, when the drive gear is rotationally driven by the rotation of the motor, the pair of left and right driven gears meshed with the drive gear are rotated in the same direction in synchronization with each other, The rotating cranks attached to the gears remain approximately parallel to each other and are rotated in synchronization and in the same direction, and therefore the links spanned between these rotating cranks maintain a horizontal position and perform circular motion in a vertical plane. occurs.

Therefore, the vehicle body attached to the link also maintains a horizontal posture and performs circular motion within a vertical plane.

Therefore, according to the amusement vehicle of the present invention, the vehicle body on which a player such as an infant rides moves in a circular trajectory in a vertical plane while maintaining a horizontal posture, so that the vehicle body does not tilt forward or backward. It performs smooth circular motions without any movement, so even young children can enjoy it safely. Moreover, since a pair of driven gears that mesh with the driving gear and a parallel crank mechanism connected to these driven gears are used as a mechanism for imparting circular motion to the vehicle body in a horizontal position, the conventional chain transmission mechanism can be used. It is possible to prevent fluctuations in load and disconnection of power transmission, which would occur when the vehicle is used, and the circular motion of the vehicle body becomes smoother, improving riding comfort.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a frame formed by welding a plurality of steel shapes, etc., and legs 2 for adjusting the installation height are attached to each of its four corners. Note that 3 in Figures 3 and 4 indicates wheels that may be provided as necessary.
After installation, the height of the legs 2 can be adjusted to lift it off the installation surface.

A drive device 4 is mounted on this pedestal 1. The drive device 4 includes a motor 5, a worm reducer 6, a drive gear 7, and a pair of left and right driven gears 8, 8.
It is formed with the following. Worm reducer 6
is for decelerating the rotation of the rotating shaft of the motor 5, and in this embodiment, the motor 5 and the worm reducer 6 are connected via a belt reducer 9. In the present invention, the reduction gear 9 may be omitted and the motor 5 and the worm reduction gear 6 may be directly connected via a shaft coupling or the like. The drive gear 7 is connected to the output shaft 6a of the worm reducer 6.
A pair of left and right driven gears 8, 8 are meshed with the drive gear 7, sandwiching it therebetween. Note that 10 in FIGS. 1 and 2 indicates a bearing that supports the gear shaft 8a of the driven gear 8.

Reference numeral 11 in the figure is a parallel crank mechanism consisting of a pair of opposing rotating cranks 12, 12, and a horizontal link 13 connecting one end of these cranks 12, 12. These connections are shown in FIG. 5, and are made by rotatably supporting a stepped connecting pin 14 at one end of the rotating crank 12, and attaching the end of the link 13 to this pin 14 via a nut 15. ing. One of the pin insertion holes 16 provided at both ends of the link 13 is a long hole as shown in FIG. This measure is to absorb some phase shift in the rotation of the rotating cranks 12, 12, etc. due to dimensional errors of these cranks. The other end of both rotating cranks 12, 12 of this parallel crank mechanism 11 is connected to the gear shaft 8.
a and 8a, respectively.

A support stand 17 is connected to the link 13 of the parallel crank mechanism 11. This support stand 17
A vehicle body 18 on which a player can ride is connected to the top. The vehicle main body 18 has seat portions 18a facing each other on which about two children or the like can sit, and its appearance is formed to imitate a ship, an airplane, an animal, a fish, a cloud, etc.

Reference numeral 19 in FIGS. 1, 3, and 4 is a control box, which houses various parts for operating and controlling the motor 5 when a coin is inserted into a coin box (not shown). There is. Also,
The control box 19 and the drive device 4 have an opening that allows the movement of the support stand 17, and are covered with a cover (not shown) attached to the stand 1.

The play vehicle having the above structure is operated for a predetermined period of time by inserting a predetermined coin into the coin box while a player such as a child is riding on the vehicle main body 18. The operation is performed by rotating a drive gear 7 in one direction at a predetermined speed through a belt reducer 9 and a worm reducer 6 by driving the motor 5, and a pair of left and right driven gears meshing with the gear 7. The gears 8, 8 are rotated in the opposite direction to the drive gear 7. Then, the rotating cranks 12, 12 connected to the gear shafts 8a, 8a rotate simultaneously in the same direction. Since these cranks 12, 12 rotate along the vertical plane, the link 13, the support base 17, and the vehicle body 19 eventually move circularly at a constant speed along the vertical plane. Note that A in FIG. 4 indicates the rotation locus of the support base 17. Since such circular motion is a composite motion of vertical motion and horizontal (or front-back) motion, it can provide the player with a variety of motions not available in the past.

Since the parallel crank mechanism 11 is driven by a gear mechanism, it is not affected by load fluctuations unlike when a chain transmission mechanism is used. Therefore, the circular motion of the vehicle body 18 can be made smooth at a constant speed, which improves riding comfort and reduces the impact on the mechanical system, allowing for long-term use without the need for particularly robust specifications. can.

Furthermore, since a chain is not used, there is no risk of the power transmission system being cut off due to load fluctuations, and even if the motor 5 suddenly stops during use, neither the drive gear 7 nor the driven gears 8, 8 Rotation in the direction is also prevented by the worm reducer 6. Therefore, the vehicle body 18 can be prevented from falling suddenly, resulting in high safety.

Although the above-mentioned embodiment is configured as described above, in implementing the present invention, unless it goes against the gist of the invention, motors, worm reducers, drive gears,
It goes without saying that the specific structure, shape, position, material, etc. of the driven gear, parallel crank mechanism, support base, vehicle body, etc. are not limited to the one embodiment described above, and can be configured and implemented in various forms. It is.

Since the present invention described above has the structure described in the above-mentioned utility model registration claims, it is possible to move the vehicle body in a circular motion along a vertical plane via a support base using a parallel crank mechanism. This satisfies the sense of play of children and other players, and since the vehicle itself performs the circular motion described above while maintaining a horizontal posture, the rider does not lean forward or arch backwards, and is stabilized. . By rotating the rotating crank of the parallel crank mechanism using a gear mechanism and eliminating the need for a chain transmission mechanism, the vehicle body can move smoothly, improving riding comfort, and also preventing the risk of breakdowns. can increase the lifespan. Furthermore, by providing a worm speed reducer between the gear mechanism and the motor to transmit power, safety can be improved by not using a chain transmission mechanism.
That is, since the present invention has the above-mentioned effects, it is possible to provide a practical amusement vehicle.
