There has been a two-wheeled vehicle toy that rotates to generate an inertial force in the direction in which the toy body stands up and acts as a gyro effect.

In addition, in order to obtain the same effect, a doll that looks like a driver is moved to the left or right by a servomotor or the like in a two-wheeled vehicle toy, and the center of gravity of the doll is controlled to the left or right with respect to the traveling direction to cause a fall In some motorcycle toys, the position of the center of gravity was shifted in the direction opposite to that to prevent falls.

However, if the flywheel is provided at the rear wheel position, or if the flywheel is provided at the center of the toy, a sufficient gyro effect can be obtained when the two-wheeled vehicle travels in the left-right direction. I couldn't do it and I fell down. Also, by mounting a simulated body that imitates a human being, it is possible to enhance the erection property of the motorcycle traveling toy, but the configuration for that becomes expensive and complicated, so it is difficult to fall down while traveling at low cost. A motorcycle toy was desired.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. A two-wheeled vehicle toy will be described as an embodiment of the present invention with reference to FIGS. The toy body 1 is roughly composed of a chassis portion 10, a steering portion 20, a flywheel portion 30,
It is composed of a continuous rod 40.

A steering portion 20 is rotatably mounted on the front portion of the chassis portion 10. The steering unit 20 includes the front wheels 2
1, the axle 22, the hanging piece 23, and the front fork 24. At the lower tip of the front fork 24,
The axle 22 is fixed. Front axle 21 on axle 22
Is rotatably attached to the shaft. In order to reduce the weight of the front wheel 21, three holes are provided symmetrically on the fan.
It is desirable that the wheels have a diameter as large as possible and are lightly provided.

A shaft 24a pivotally mounted on the chassis 10 is provided above the front fork 24, and the front fork 24 is rotatably provided. Further, the shaft 24a is provided so as to project from the chassis portion 10, and the hanging piece 23 is fixed to the end portion of the shaft 24a extending from the chassis portion 10. At this time, the hanging piece 23 is provided so as to form a right angle with respect to the direction of the front wheel 21.

A rear wheel 11 and a large pulley 11a fixed to both ends of an axle 12 at the rear of the chassis 10 in the traveling direction.
Is mounted on the chassis 10. The front wheel 21 and the rear wheel 11 are in contact with the road surface, and the rear wheel 11 rotates, so that the two-wheeled traveling toy travels.

The flywheel section 30 comprises a first drive means (motor) 32, a flywheel cover 31, a flywheel 33 and a shaft 34, and the chassis section 1
A flywheel unit 30 is rotatably supported by a shaft 34 in a hole 10a provided in a central portion of 0.
The flywheel 32 is configured such that the flywheel 33 rotates as the motor 32 rotates. Also,
Due to the heavy mass of the flywheel 33,
It takes about 10 seconds until the motor 32 starts rotating and reaches a constant rotation speed. When the flywheel 33 reaches a constant rotational speed, the gyro effect can be produced by the inertial force of the flywheel 33. The gyro effect is that the force to keep the direction of the rotation axis constant works, so that the toy body 1 is placed on either the left or right side.
It is possible to prevent the toy main body 1 from falling when the upright inertia force of the gyro effect is exerted when the toy body 1 is about to fall. Further, in order to utilize the gyro effect of the flywheel 33, it is necessary to rotate the flywheel 33 in the same direction as the drive wheel, and in the embodiment, it is provided so as to rotate in the same direction as the rear wheel 11.

The flywheel cover 31 is provided with a hanging projection 31a, the tip of which engages with the connecting rod 40. In addition, the connecting rod 40 includes the hanging projection 31a.
Then, the hanging piece 23 of the steering unit 20 is hung from the chassis unit 1
The front wheel 21 is provided so as to be always parallel to 0.
The direction of the flywheel section 30 is always the same. Further, in the embodiment, they are provided in parallel, but the gyro effect can be expected to some extent even if the connecting rod 40 and the chassis portion 10 are not in parallel.

The battery 60 is provided in the rear portion of the chassis portion 10. As the battery 60, any battery and power source that can be built in the toy body may be used. For example, primary batteries (manganese batteries, alkaline batteries,
It is preferable to use button type batteries / lithium batteries), but other power sources include secondary batteries (nicad batteries, nickel-hydrogen batteries, lithium-ion batteries, lead-acid batteries), fuel cells, and other solar cells. Alternatively, a capacitor that temporarily stores electricity may be used. Although not shown, a power switch for driving each drive unit is provided. When the power switch is turned on, the drive unit is driven to drive the two-wheeled vehicle toy, and when the power switch is turned off, the traveling is stopped. Further, immediately after the power switch is turned off, the flywheel 33 continues to rotate due to inertial force, and immediately when the power is turned on, the time required to reach a certain speed can be shortened.

As shown in FIG. 3, the flywheel unit 30 is swung along with the movement of the steering unit 20 along with the linkage rod 40. Further, the connecting rod 40 is provided so as to operate so as to be always parallel to the chassis body, and has a function of a parallel link. FIG. 3 (B) shows a normal state in which the vehicle is traveling straight ahead. When the steering unit 20 is tilted to the left as shown in FIG.
Similarly, 0 also leans to the left, and by tilting the steering portion 20 to the left, the toy body 1 itself tends to tip over to the left rear, but due to the gyro effect due to the rotation of the flywheel portion 30, the right The toy body does not fall down due to the standing inertial force acting forward.

Further, in the conventional case, since the flywheel part cannot change the direction of the flywheel to the rear wheel part or the center part of the toy, the toy body 1 is applied with a force to the left rear. , The gyro effect due to the rotation of the flywheel section works only to the right of the toy body 1. Therefore, the vector of the force in the falling direction and the vector of the force for standing up do not exactly coincide with each other. The toy body 1 is prone to tipping over when the parts are rotated and run in the left-right direction. Further, in the above-mentioned embodiment,
Since the force vector in the direction of accurate fall and the force vector for standing up work in the opposite directions, the forces are balanced and do not fall.

A second drive portion is provided in the rear center portion of the chassis portion 10 to rotate the rear wheel 11. A method for driving the rear wheels will be described. Rear wheel 12
The rotation of the second drive unit (motor) 50 is transmitted to rotate. When the motor 50 rotates,
The pinion gear 51 attached to the motor shaft rotates, causing the first gear 52 to rotate. The rotation from the first gear 52 is transmitted to the second gear 53. On the opposite side of the second gear 53, a small pulley 58 is mounted on the same shaft as the second gear 53.
Rotation from the second drive unit 50 is transmitted to the rear wheel 12 by a belt 70 that is stretched between the small pulley 58 and the large pulley 11a. The rotation speed from the motor is decelerated every time it passes through the gear, and the rotation force is increased.

Further, as in the embodiment, a gear group is provided on the right side of the chassis and a pulley for driving the rear wheel 11 is separately provided on the left side, so that the center of gravity of the toy body 1 is at the center of the toy. Therefore, the weights of the gear group and the pulley are adjusted and provided. As a result, the toy body is provided so as not to lose its balance and fall during traveling.
As described above, it is desirable that the weights of the gear group and the pulley are adjusted so that the center of gravity of the toy body is located at the center of the toy.

A motor 32 provided on the flywheel unit 30 is used to swing the flywheel unit 30.
Since the motor wire 35 for supplying electric power also swings with the swing of the flywheel portion 30, the wire breaks and the tension of the motor wire connecting the motor 32 and the toy body acts. Therefore, in order to drive the vehicle to the left or right, the tension acts as a load when the steering portion is rotated to the left or right, and the delicate balance may be impaired. Therefore, it is desirable to provide a current collector such as a slip ring.

A current collector such as a slip ring is
Because of the high cost, in the embodiment as shown in FIG. 4, the shaft 34 is made of a metal having high conductivity, and the motor wire 35 is fixed to the inner end of the flywheel portion 30 so that the motor wire 35 can be energized. The other end of the motor wire 35 is connected to the motor 32. Further, the energizing terminal 19 is provided so as to press the end portion of the shaft 34 outside the flywheel portion 30. The energizing terminal 19 is fixed to the chassis portion 10 and energizes the energizing terminal 19 to the motor 32 even when the shaft 34 rotates. Further, by passing electricity through each of the upper and lower shafts 34, it is possible to obtain a two-pole current collecting device for exchanging electricity between the fixed side and the rotating side, which can be manufactured at low cost.

Further, in order to stably drive the two-wheeled traveling toy, it is desirable to increase the wheel diameter because the wheels 11 and 21 of the toy body 1 themselves have a gyro effect. In addition, when a heavy wheel is used, straight running stability is improved, but the standing inertial force due to the gyro effect obtained by the rotation of the flywheel and the gravity applied to the toy body 1 when traveling in the left-right direction and the motorcycle is tilted. It is easy to fall over.

Further, when the flywheel 33 is not sufficiently rotated, the standing inertial force due to the gyro effect is weak and it is easy to fall, so the flywheel 33 is rotated by the rotation of the motor 32 and the rotation is stabilized about 10 If the wheels of the toy are installed on the road surface after a lapse of seconds, the toy can run smoothly.

In the case of improving straightness and turning the steering wheel to the right or left, it is difficult to bend due to the gyro effect in the past, but since the link exerts a gyro effect on the direction of the steering wheel, two wheels are used. The stability of the running toy's posture is improved.

The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the embodiments and can be variously modified within the technical scope described in the claims. The shape of the moving toy according to the present invention may not be as described above.

As shown in FIGS. 5 to 8, it is a diagram showing an embodiment in which a swingable weight is provided on the top of the toy body 1. In the embodiment, the second drive unit (motor) 50 is a drive unit for swinging a weight provided on the top of the toy body 1 for swinging motion, and a drive unit for driving the rear wheels 12. The rotation force of the toy body is used to swing and drive the toy body 1. The rotation of the second drive unit (motor) 50 is transmitted and rotated. When the motor 50 rotates, the pinion gear 51 fixed to the motor shaft rotates, causing the first gear 52 to rotate. The rotation from the first gear 52 is transmitted to the second gear 53. On the opposite side of the second gear 53, a small pulley 58 is mounted on the same shaft as the second gear 53. The second drive unit 50 is driven by the belt 70 that is stretched between the small pulley 58 and the large pulley 11a.
The rotation from is transmitted to the rear wheel 12.

Further, the rotation from the motor 50 is performed by the second gear 5
3 to the third gear 54, the worm gear 54a is fixed to the opposite surface of the third gear 54 on the same shaft as the third gear 54, and the worm gear 54a rotates. In addition, the crank gear 55 rotates with the rotation of the worm gear 54 a, and the crank 55 a fixed to the crank gear 55 a
Is making a crank motion. Further, the joint 56 pivotally mounted on the crank 55a is converted from a rotational motion to a motion close to a reciprocating motion by the action of the crank 55a, and the swing unit 57 swingably provided on the chassis unit 10 is attached to the chassis unit. Centering on a shaft 57b that is pivotally attached to 10,
A shaft 57a provided on the rocking portion 57 and a joint 56 are pivotally attached to each other so that the joint 56 reciprocates and rocks. A weight 59 is provided above the swinging portion 57.

As shown in FIGS. 8A to 8D, the center of gravity of the toy body 1 is changed by providing a weight 59 on the toy body 1 and swinging the weight 59 in the left-right direction with respect to the traveling direction. As described above, due to the swinging effect of the weight 59, the two-wheeled vehicle toy travels to the left when the center of gravity shifts to the left, and to the right when the center of gravity shifts to the right. Further, in the conventional two-wheeled vehicle toy, when the weight 59 is swung in this manner, the two-wheeled vehicle toy is prone to fall,
Due to the gyro effect, the standing inertial force acts, and it is possible to run in the left and right directions without falling.

Further, if the swinging portion 57 is provided so as to be covered with a doll cover or the like which is not shown but imitates a character such as a human being, the doll can be produced as if it were operating a two-wheeled vehicle toy. It will be possible. Further, the doll's arms, legs and other parts may be provided so as to be movable in accordance with the swinging movement. At this time, be careful not to disturb the left and right balance by the doll when traveling straight ahead, etc.
It is desirable that the dolls are provided symmetrically or that the dolls have the same weight.

Further, in the embodiment, the same driving means as the second driving force for driving the rear wheels is used as the driving force for swinging the weight 59 in the left-right direction, but each driving force is provided separately. I don't care. Further, in order to easily make the swinging part heavy, it is desirable to provide the battery part 60 on the swinging part as in the embodiment, but it may be provided on the chassis part.
