Is.

Further, as shown in FIG. 5, the cam drive unit 4 mounted at a substantially central portion of the vehicle body 14 has a servo motor 40 as a drive source, a main shaft 44, and a speed reduction mechanism 41. The main shaft 44 includes a first bevel gear 81 and a first bevel gear 81 of the first bevel gear 81 and the second bevel gear 82 which are cam operating portions for operating the link base 80 in the front wheel rotating means 8 described below in the vicinity of the front end. . The speed reduction mechanism 41 is composed of a plurality of gear trains arranged so that the driving force of the servo motor 40 can be transmitted to the main shaft 44. The first bevel gear 81 and the second bevel gear 82 of the cam operating portion are meshed so as to be able to transmit rotation between two axes intersecting at an arbitrary angle. Then, as shown in FIG. 7 (a), the second bevel gear 82 is formed with a pushing portion 83 for pushing the front wheel turning means 8. The

Further, the front wheel rotating means 8 incorporated in the front of the center of the vehicle body 14 includes a link base 80 that is pivoted near the front end of the vehicle body 14 and transmits the force from the pushing portion 83, a front fork 7, and a link base 80. And a connecting bar 84 that connects the front fork Ί and the front fork Ί. The link base 80 is formed with a fitting portion for fitting the pushing portion 83 of the second bevel gear 82. The front wheel rotating means 8 drives the cam drive unit 4 in response to a remote operation signal from the transmitter 110, thereby reducing the speed reduction mechanism 41, the main shaft 44, the first bevel gear 81, and the second bevel gear 82. By rotating the link base 80 via the front fork 7, the front fork 7 can be rotated in the left-right direction about the caster shaft 62 as shown in FIG. 7 (d).

As shown in FIGS. 5 and 8 (a), the auxiliary wheel projecting means 5 includes a pair of elastic members arranged so as to be able to bias the auxiliary wheel holding portion 52, the pressing cam 50, and the auxiliary wheel holding portion 52. A helical coil spring 56 which is a body. The pair of assisting wheel holding parts 52 are arranged so as to hold the auxiliary wheel 12 and to be rotatable in the vertical direction with respect to the vehicle body 14. The pressing cam 50 is attached to the main shaft 44 so as to be rotatable by the cam drive unit 4, and has pressing portions 58 at the left and right ends that press the auxiliary wheel holding portion 52 when the main shaft 44 rotates.

The auxiliary wheel projecting means 5 drives the cam drive unit 4 in response to a remote operation signal from the transmitter 110 to rotate the main shaft 44 and the pressing cam 50 via the speed reduction mechanism 41. Thus, one of the pair of auxiliary wheel holding parts 52 is pressed by the pressing part 58, and the auxiliary wheel 12 is moved outwardly of the vehicle body 14 as shown in FIG. The auxiliary wheel holding portion 52 is configured to be rotatable so as to protrude to a predetermined position (position in the drift traveling state). Then, the auxiliary wheel protruding means 5 rotates the assisting wheel holding portion 52 so that the auxiliary wheel 12 is returned to a predetermined position near the vehicle body 14 (position in the normal traveling state) by the elastic force of the torsion coil spring 56. It is configured to be movable. Then, as shown in FIG. 9 (a), this traveling toy 1 allows the traveling toy 1 to travel by placing the traveling toy 1 on the traveling surface and driving the rear wheel 11 by the rear wheel drive unit 2. Start. In the normal traveling state of the traveling toy 1, a caster angle is provided so that the upper side of the caster shaft 62 is inclined rearward of the lower side, and the trail is set with the grounding point of the front wheel 10 being rearward of the caster axis. Therefore, this traveling toy 1 can generate a caster effect that is adjusted by synergy between the caster angle and the trail. As a result, the traveling toy 1 can perform a straight traveling stably with the front wheel 10 facing forward if the vehicle body 14 is vertical. In addition, this traveling toy 1 travels so that when the vehicle body 14 is tilted, the handle is rotated by a caster effect so that the front wheel 10 is directed in the direction in which the vehicle body 14 is inclined, and the front wheel 10 is moved in the direction in which the vehicle body 14 is inclined. By moving the support line of the vehicle body 14 that connects the contact point of the front wheel 10 and the contact point of the rear wheel 11 to the lower side of the center of gravity, the traveling toy 1 can be prevented from falling and the traveling can be continued.

Then, in order to cause the direction control unit 3 to turn, the direction control unit 3 can, for example, move the front wheel 10 when the traveling toy 1 is in a normal traveling state, that is, in a state where the vehicle body 14 is in a vertical rectilinear posture. When the vehicle body is slightly rotated leftward with respect to the vehicle body, a force directed to the right side is applied to the vehicle body 14 by the action of inertial force. As a result, as shown in FIG. 9 (b), the vehicle body 14 tilts to the right in the direction opposite to the direction of rotation of the front wheel 10. The traveling toy 1 has a predetermined position in the right direction in which the front wheel 10 is inclined due to the caster effect caused by the inclination of the vehicle body 14 (position when the steering wheel turning angle conforms to the speed and inclination angle). However, the right turning angle of the steering wheel is slightly smaller than the right turning angle of the steering wheel according to the inclination of the vehicle body 14 due to the caster effect due to the force of turning the steering wheel slightly to the left by the direction control unit 3 As a result, the vehicle body 14 continues to turn right by maintaining the right inclination without resetting the right inclination of the vehicle body 14.

When turning left, the player operates the steering wheel so as to cut the front wheel 10 to the right side, so that the traveling toy 1 tilts the vehicle body 14 to the left and the front wheel so that the handle is turned to the left by the caster effect. Turn 10 to the left. Then, by applying a slight force to turn the handle to the right by the direction control unit 3, the traveling toy 1 maintains the left inclination of the vehicle body 14 by slightly reducing the angle at which the handle can be turned to the left by the caster effect. Continue to turn the running toy 1 to the left. JP2009 / 058225

12

Then, when it is desired to shift from the straight traveling of the normal traveling or the traveling state of the right turning or the left turning state to the drift traveling, first, the direction control unit 3 is controlled to rotate the front wheel 10 slightly to the left, for example. As a result, the traveling toy 1 shifts to a right-turning traveling posture inclined to the right as shown in FIG. 9 (b). Then, by maintaining the state in which the front wheel 10 is rotated to the predetermined position (the handle turning angle slightly smaller than the position when the handle turning angle conforms to the speed and the inclination angle) is maintained, the traveling toy 1 Will continue to turn right. Next, when the traveling toy 1 is in this turning traveling state, if the auxiliary driving wheel projecting means 5 is operated by the cam drive unit 4 to maintain this operating state, the right side assist that is in the turning inner direction is maintained. The state where the wheel 12 protrudes to a predetermined position outside the vehicle body 14 is maintained. At this time, in this traveling toy 1, the front wheel rotating means 8 is operated so that the handle is directed to the left, which is the outward direction of the turning, and the operated state is maintained so that the front wheel 10 is turned in the rotating direction. The state rotated to the predetermined position of the left direction which is a reverse direction is maintained.

As described above, the traveling toy 1 further moves the vehicle body 14 that has been tilted in the turning state as shown in FIGS. 1, 2, and 9 (c) by turning the handle to the outside during the turning. The vehicle is configured so that the vehicle can be shifted to a drifting driving posture in which the vehicle body 14 is inclined until the auxiliary wheel 12 is brought into contact with the traveling surface.

Further, the traveling toy 1 transmits a control signal for driving the control unit 102 of the receiver 100 mounted on the traveling toy 1 to the cam driving unit 4 in response to a remote operation signal from the transmitter 110. It is preferable to form a control signal that is sent to the unit 4 and that performs an operation of increasing the driving force applied from the rear wheel drive unit 2 to the rear wheel 11 to the rear wheel drive unit 2. As a result, the traveling toy 1 can easily shift to the drift traveling posture by performing the operation of tilting the vehicle body 14 and causing the rear wheel 11 to idle.

Further, when the traveling toy 1 is in the drift traveling state, the cam driving unit 4 is driven in response to the remote operation signal from the transmitter 110, and the pressing cam 50 is rotated to the position of the normal traveling state. As a result, the auxiliary wheel holding portion 52 is released from the pressing force of the pressing portion 58 of the pressing cam 50. For this reason, the assisting wheel holding part 52 is rotated to the position of the normal traveling state by the elastic force of the torsion coil spring 56. At this time, the traveling toy 1 has the front wheel turning means 8 in the normal position. Returning to the position, the front wheel 10 can be swung in the left-right direction according to the front and turning. For this reason, the steering wheel is turned so as to be turned inward of the turn, the balance of the vehicle body 14 returns to the original state, and the rear wheel drive unit 2 continuously drives the rear wheel 11 so that the caster effect is achieved. This makes it possible to return the vehicle body 14 to the normal driving posture and perform stable driving again.

Then, the front wheel rotating means causes the auxiliary wheel protruding means 5 to project the catching wheel 12 leftward or rightward so that the traveling toy 1 drifts and the front wheel 10 is moved in the protruding direction of the auxiliary wheel 12. Rotate to the right or left, which is the opposite direction, and ground the auxiliary wheel 12 that protrudes to the running surface. Further, the cam driving unit operates the auxiliary wheel protruding means 5 and the front wheel rotating means, and maintains the operated state. In this traveling toy 1, the control unit of the receiver responding to the operation signal from the transmitter generates a predetermined control signal, and the rear wheel drive unit, the direction control unit, the cam drive unit 4 By driving, go straight, turn and drift. As shown in FIG. 3, the transmitter 110 is for a player who remotely controls the traveling toy 1 to hold and transmit an operation signal. Then, the transmitter 110 displays a power switch 115, a traveling operation unit 120 for instructing the traveling toy 1 to move forward, stop, reverse, and turn left and right, as well as a turning operation unit 122, and the presence / absence of power. An electric power indicator for transmitting, and an antenna 116 for transmitting radio waves, and a drift operation section 124 for instructing the traveling toy 1 to shift to the drift traveling posture on the upper surface.

The transmitter 110 is provided with the drift operation unit 124 as two switches for turning right and turning left, and the traveling toy 1 in the normal running state is connected to one of the drift operation units 124 ( It is also possible to shift the traveling toy 1 to drift traveling by operating (for turning right or turning left).

Then, as shown in FIG. 4, the transmitter 110 includes the operation units 120, 122, and 124 described above, a control unit 112 that generates a predetermined signal in accordance with the player's operation, and a code sent from the control unit 112. A transmission circuit 111 that modulates the converted signal, an amplifier 118, an antenna 116 that transmits this signal, a power source (not shown), and the like. The receiver 100 receives a radio signal transmitted from the transmitter 110 via the antenna 106 and demodulates the receiver circuit 101, an amplifier 108, and decodes the demodulated signal to drive each of the drive units 2-4. A control unit 102 that generates a control signal for driving the power source, and a power source (not shown). It should be noted that it is preferable that the passive element of the transmitter circuit 111 and the receiver circuit 101 of the transmitter 110 and the receiver 100 is a detachable crystal resonator so that the player can change the frequency. is there. Here, the cam drive unit 4 operates a front wheel rotation unit and a catching wheel projecting unit 5 described later, and detects a rotation angle between a servo motor as a drive source and a main shaft as a drive shaft. Equipped with a rotary potentiometer. Then, when the traveling toy 1 is drifted, the control unit 102 drives the servo motor and monitors the detected value by the potentiometer, stops the servo motor when the main shaft rotates to a predetermined rotation angle, The servo motor is controlled so that the stopped state is maintained by the servo motor. The control unit 102 enters the turning state when the player's turning operation signal (left turning operation signal or right turning operation signal) is input, and when the drift operation signal is received in this turning state, the front wheel A drift travel command that rotates 10 in the direction opposite to the turning direction is sent to the cam drive unit 4. Thus, for example, if the drift operation is performed while the player is performing the left turn operation, the cam drive unit 4 is configured so that the front wheel 10 rotates in the right direction (the direction opposite to the turn direction). The servo motor will be driven. When switching from straight running to turning, if the right operation signal is output by operating the lever of the turning operation unit 122, the direction control unit 3 turns the front wheel 10 slightly to the left, When the front wheel 10 rotates to the left, the vehicle body 14 of the traveling toy 1 tilts to the right from the vertical straight state, and the steering wheel is turned by the caster effect described later by the right inclination of the vehicle body 14 so that the front wheel 10 faces the right. The traveling toy 1 turns right.

Then, when the player operates the drift operation unit 124 with the vehicle body 14 tilted to the right and turning right, a drift operation signal is transmitted from the transmitter 110, and the traveling toy 1 A drift travel command is output from the control unit 102 to the cam drive unit 4. When a drift travel command is input to the cam drive unit 4, the cam drive unit 4 is operated and the front wheel rotating means 8 rotates the front wheel 10 to the left opposite to the turning direction. Further, the cam drive unit 4 projects the auxiliary wheel 12 on the inner side of the turn, which is the tilt direction, by operating the catching wheel projecting means 5 in cooperation with the operation of the front wheel rotating means 8.

The operation of the drift operation section 124 is effective only when the lever of the swing operation section 122 is operated, and a drift operation signal is output, and the drift operation signal is caused by an incorrect operation during straight traveling. Is output to prevent the traveling toy 1 from being overturned.

Thus, the player can drive the driving motor of the rear wheel driving unit 2 and rotate the rear wheel 11 to operate the traveling toy 1 by operating the traveling operation unit 120. In addition, the player can operate the turning operation unit 122 while the traveling toy 1 is in the straight traveling state, thereby driving the direction control unit 3 to tilt the traveling toy 1 to perform the turning traveling. it can. Further, the player operates the drift operation unit 124 when the traveling toy 1 is in the turning traveling state. In this way, the cam driving unit 4 is driven and the front wheel rotating means 8 and the auxiliary wheel protruding means 5 are operated, so that the traveling toy 1 can be further tilted to perform drift traveling. Next, the structure of the traveling toy 1 according to the embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 5, the traveling toy 1 according to the present invention includes a vehicle body 14 imitating the shape of a motorcycle, a front wheel 10, a rear wheel 11, and the like. The vehicle body 14 is equipped with a rear wheel driving unit 2, a direction control unit 3, a front wheel rotating means 8, a catching wheel projecting means 5, a receiver 100, a battery 90, and the like. The traveling toy 1 aims to improve running stability by lowering the center of gravity by positioning the relatively heavy battery 90 and the rear wheel drive unit 5 on the lower side of the vehicle body 14.

The rear wheel drive unit 2 is disposed in the lower rear part of the vehicle body 14, and is a belt vehicle that transmits a rear wheel drive motor that is a drive source for rotating the rear wheel 11 and the rotational force of the rear wheel drive motor. And a timing belt. A rear wheel holding portion 22 for holding the rear wheel 11 is pivotally supported by a shaft formed on the vehicle body 14 on the same axis as the drive shaft of the rear wheel driving motor, and in the vicinity of the rear end of the rear wheel holding portion 22 Are pivotally supported by a rear wheel cushioning portion 24 incorporating an elastic body such as a coil spring. Since the other end of the rear wheel cushioning portion 24 is pivotally supported behind the vehicle body 14, the impact received by the rear wheel 7 from the running surface during traveling is the rear wheel holding portion 22 and the rear wheel cushioning portion 24. It will be absorbed by. Further, the traveling toy 1 is formed with an arm portion 60 formed integrally with a case of a direction control portion 3 described later in front of the upper portion of the vehicle body 14 so as to protrude forward. A caster shaft 62 is attached to the distal end portion of the arm portion 60, and the upper portion of the caster shaft 62 is inclined rearward. The traveling toy 1 is a front fork that holds the front wheel 10, and includes a front fork 7 that is disposed so as to be pivotable in the left-right direction with respect to the vehicle body 14 around the caster shaft 62. The front fork 7 includes a cylindrical front wheel holding portion 78 that holds a front wheel 10 at a lower portion, and a vehicle body support portion 70 that supports an arm portion 60 that is a tip portion of a vehicle body 14 at an upper portion. The

Thus, the traveling toy 1 is set so that the caster shaft 62 has a predetermined caster angle with the upper portion of the caster shaft 62 tilted rearward, and the front wheel 10 has a predetermined tray. Giving Therefore, the traveling toy 1 can stably travel straight ahead with the front wheels 10 facing forward if the vehicle body 14 of the traveling toy 1 is vertical due to the synergistic effect of the caster angle and the trail. In addition, when the vehicle body 14 is tilted, the traveling toy 1 produces a caster effect that rotates the steering wheel so that the front wheel 10 is directed in the direction in which the vehicle body 14 is tilted. This caster effect causes the front wheel 10 to tilt in the direction in which the vehicle body 14 is tilted. The vehicle body 14 that connects the grounding point of the front wheel 10 and the grounding point of the rear wheel 11 is moved to a position below the center of gravity so as to prevent the vehicle from falling, and the travel is continued. Can do.

The vehicle body support portion 70 is formed by integrally molding a pair of upper and lower parallel upper and lower plates 70a and 70b formed in a substantially triangular shape and a pair of sliding shafts 76. The sliding shaft 76 connects the upper plate 70a and the lower plate 70b, and is formed so as to protrude further downward from the lower plate 70b. The lower portion of the sliding shaft 76 is mounted so as to be slidable in the vertical direction on the central axis of the front wheel holding portion 78 so as not to be detached from the front wheel holding portion 78. Further, the coil spring 74 is mounted on the lower surface of the lower plate 70b and the upper surface of the front wheel holding portion 78, so that the vehicle body holding portion 70 swings up and down with respect to the front wheel holding portion 78 via the pair of coil springs 74. It is supported freely. As a result, the impact received by the front wheel 6 from the traveling surface during traveling is absorbed by the coil spring 74 of the front fork 7.

The direction control unit 3 is housed in a case disposed in front of the upper part of the vehicle body 14. Then, as shown in FIG. 6 (a), the direction control unit 3 is attracted by a solenoid coil 30 in which a current flows in response to a remote operation signal from the transmitter 110 and a magnetic field generated by the solenoid coil 30. · A magnet 32 that generates a repulsive force, and a connecting rod 34 that connects the magnet 32 and the front fork 7 are provided.

The solenoid coil 30 is arranged in a substantially front-rear direction of the vehicle body 14 so that the central axis of the solenoid coil 30 is close to one of the slide shafts 76 of the pair of slide shafts 76. In addition, the holding member of the solenoid coil 30 is formed with a cylindrical portion protruding forward of the solenoid coil 30 so that the magnet 32 can be slidably moved in the front-rear direction along the central axis of the solenoid coil 30. Has been. Then, the connecting rod 34 is fixed to the magnet 32 so as to be disposed on the central axis of the solenoid coil 30 in front of the magnet 32. Yes. Further, a U-shaped connecting portion 36 is formed at the tip of the connecting rod 34, and the connecting portion 36 is pivotally connected to the sliding shaft 76 of the front opening 7.

Then, the direction control unit 3 causes the current to flow through the solenoid coil 30 by the control unit 102 of the receiver 100 in response to the remote operation signal from the transmitter 110, thereby allowing the direction of FIG. 6 (b) or FIG. 6 (c). As shown, the magnet 32 can be attracted and repelled, and the magnet 32 can be moved forward or backward. Then, by moving the connecting rod 34 by the movement of the magnet 32, the attraction / repulsive force of the magnet 32 and the solenoid coil 30 is transmitted to the front fork 7 via the connecting rod 34, and the front wheel holding portion 78 of the front fork is transmitted. The front wheel 10 held by the wheel can be rotated leftward or rightward about the caster shaft 62. In addition, since a gap is formed in the connecting portion 36 with respect to the sliding shaft 76, the front fork 7 can be rotated to a sufficient handle turning angle for drift driving described later.

As shown in FIG. 5, the cam drive unit 4 incorporated in the substantially central portion of the vehicle body 14 has a servo motor 40 as a drive source, a main shaft 44, and a speed reduction mechanism 41. The main shaft 44 includes a first bevel gear 81 and a first bevel gear 81 of the first bevel gear 81 and the second bevel gear 82 which are cam operating portions for operating a link base 80 of the front wheel rotating means 8 described later. Yes. The main shaft 44 includes a potentiometer 130 at the rear end. The speed reduction mechanism 41 is composed of a plurality of gear trains arranged so as to be able to transmit the driving force of the servo motor 40 to the main shaft 44. The first bevel gear 81 and the second bevel gear 82 of the cam operating portion are meshed so as to be able to transmit rotation between two axes intersecting at an arbitrary angle. Then, as shown in FIG. 7 (a), a pushing portion 83 that pushes the front wheel turning means 8 is formed on the upper surface of the second bevel gear 82 disposed in front of the center of the vehicle body 14. The pushing portion 83 has a substantially cylindrical shape, and has a convex portion provided such that a part of the rear portion projects outward.

Further, the front wheel rotating means 8 incorporated in the center front of the vehicle body 14 is provided with a link base 80 which is pivotally installed near the front end in the vehicle body 14 and transmits the force from the pushing portion 83, the front fork 7, and the link base. A link mechanism comprising a pair of connecting bars 84 that connect 80 and the lower plate 70b of the vehicle body support 70 that is the upper part of the front fork 7. Link base 8225

19

In 80, a fitting portion for fitting the pushing portion 83 of the second bevel gear 82 is formed. The fitting portion of the link base 80 is a substantially circular opening formed corresponding to the shape of the pushing portion 83 of the second bevel gear 82, and corresponds to the convex portion of the pushing portion 83. A recess is provided. Accordingly, when the cam drive unit 4 is driven in response to a remote operation signal from the transmitter 110, the second bevel gear 82 and the pusher 83 are rotated via the speed reduction mechanism 41, the main shaft 44, and the first bevel gear 81. Then, the turning force is transmitted by the contact between the convex side surface of the pushing portion 83 and the concave side surface of the fitting portion formed on the link base 80. As a result, the front wheel rotating means 8 that is a link mechanism operates, and the front fork 7 rotates left and right about the caster shaft 62.

Also, as shown in Fig. 7 (b) and Fig. 7 (c), the link base 80 is rotated by the rotation of the front fork 7 until the handle turning angle θ1 reaches 15 °, for example. Even so, a predetermined gap is formed in the circumferential direction so that the concave side surface of the fitting portion of the link base 80 comes into contact with the convex portion of the pushing portion 83 and force is not transmitted.

As a result, the direction control unit 3 described above is driven, and even if the front fork 7 is rotated as shown in FIGS. 6 (b) and 6 (c), FIGS. 7 (b) and 7 (7) As shown in c), the front fork 7 does not rotate so that the fitting portion of the link base 80 is locked by the pushing portion 83 and the handle turning angle Θ 1 becomes 15 ° or more.

As shown in FIG. 7 (d), the front wheel rotating means 8 can rotate the second bevel gear 82 until the rotation angle ω reaches 45 °, and the rotation angle ω is 4 The handle angle 0 2 at 5 ° was set to 30 °. Then, the rotation angle ω of the second bevel gear 82 is indirectly detected in the grave by the potentiometer 130 provided on the main shaft 44. Then, the control unit 102 receives this detection value and executes operation control of the servo motor 40 of the cam drive unit 4.

Specifically, the control unit 102 keeps the rotation angle ω of the second bevel gear 82 fixed at 0 ° when the traveling toy 1 is in a normal traveling state (a straight traveling or turning traveling state). Stop servo motor 40. When the control unit 102 receives the drift travel command, the control unit 102 operates the servo motor 40 until the rotation angle ω reaches 45 ° by moving the second bevel gear 82 to 45 °. The servo motor 40 is stopped so that the second bevel gear 82 is fixed and maintained at a rotation angle of 45 °. Further, when returning from the drift travel, the control unit 102 operates the servo motor 40 until the rotation angle ω of the second bevel wheel 82 again becomes 0 °, and the rotation angle ω is in the state of 0 °. Then, the servo motor 40 is stopped so that the second bevel gear 82 is fixed and maintained.

As shown in FIGS. 5 and 8 (a), the auxiliary wheel protruding means 5 disposed substantially at the center of the vehicle body 14 includes a pressing cam 50 and a pair of auxiliary wheel holding portions 52 that hold the catching wheel 12. And a pair of torsion coil springs 56. The pressing cam 50 is fixed to the main shaft 44 so as to be rotatable by the cam drive unit 4. The pressing cam 50 has rod-shaped pressing portions 58 at the left and right ends of the rear surface that press the auxiliary wheel holding portion 52 when the main shaft 44 rotates. The assisting wheel holding part 52 is disposed so as to be rotatable in the vertical direction with respect to the vehicle body 14. The auxiliary wheel holding portion 52 is substantially L-shaped, and holds the auxiliary wheel 12 at one end, and the other end is inserted into the vehicle body 14. Further, the auxiliary wheel holding portion 52 is disposed such that the upper surface of the portion inserted into the vehicle body 14 can come into contact with the lower surface of the pressing portion 58 of the pressing cam 50. The torsion coil spring 56 is an elastic body that is arranged so as to be able to bias the auxiliary wheel holding portion 52. Further, the torsion coil spring 56 is inserted through a shaft serving as a rotation center of the assisting wheel holding portion 52 so that both end portions thereof are in contact with the inner surface of the vehicle body 14 and the auxiliary wheel holding portion 52.

Therefore, if the cam drive unit 4 is driven in response to a remote operation signal from the transmitter 110, the pressing cam 50 rotates together with the main shaft 44 via the speed reduction mechanism 41, and the pressing unit 58 is a pair of auxiliary wheels. One auxiliary wheel holding portion 52 of the holding portions 52 is pressed to protrude the auxiliary wheel 12 to a predetermined position outside the vehicle body 14 (a position in the drift traveling state) as shown in FIG. 8 (b). In this way, the auxiliary wheel holding portion 52 rotates. Further, if the cam drive unit 4 is rotated in the reverse direction and the pressing cam 50 is returned to the original arrangement state, the auxiliary wheel 12 is moved to a predetermined position near the vehicle body 14 (normal running state) by the elastic force of the torsion coil spring 56. The auxiliary wheel holding portion 52 is rotated so as to return to the position at (5), and the auxiliary wheel protrusion means 5 and the auxiliary wheel 12 are restored to their original state as shown in FIG. 8 (a). It becomes.

The auxiliary wheel projecting means 5 operates so as to be interlocked with the front wheel rotating means 8 that is driven by the control unit 102 controlling the potentiometer 130 and the servo motor 40. A force and a drive source may be provided separately, and the operations of the front wheel turning means 8 and the auxiliary wheel protruding means 5 may be controlled by the control unit 102.

Hereinafter, the traveling procedure of the traveling toy 1 and the operation when the traveling toy 1 in the normal traveling state shifts to the drift traveling will be described. Note that only the right direction is the turning direction.

First, as shown in FIG. 9 (a), the player operates the operation unit 120 of the transmitter 110 so that the traveling toy 1 is placed on the traveling surface and the rear wheel driving unit 2 drives the rear wheel 11. By doing so, the traveling toy 1 starts traveling. In this state, since the vehicle body 14 is traveling in a vertical state, the traveling toy 1 travels with the front wheel 10 facing straight forward due to the caster effect. In addition, when the vehicle body 14 is inclined while the vehicle body 14 is traveling and the left and right balances are unbalanced, the traveling toy 1 causes the vehicle body 14 to incline the front wheel 10 by traveling in the inclination direction due to the caster effect. Move in the direction. As a result, the traveling toy 1 changes the support line of the vehicle body 14 connecting the grounding point of the front wheel 10 and the grounding point of the rear wheel 11 to the direction in which the traveling toy 1 is inclined and moves it below the center of gravity of the traveling toy 1. In this way, the vehicle body 14 can be returned to the vertical position and the balance of the vehicle body 14 can be maintained. That is, the traveling toy 1 can stably travel with the vehicle body 14 in a straight traveling posture.

When the traveling toy 1 is in a stable normal straight traveling state, when the player tilts the turning operation unit 122 of the transmitter 110 to the right, as shown in FIG. 6 (b), the direction control unit 3 Rotate the front wheel 10 slightly to the left (ie, in the opposite direction to the operating direction). As a result, an inertial force is applied to the vehicle body 14 to apply a force to turn the vehicle body 14 to the right, and the vehicle body 14 is tilted to the right as shown in FIG. 9 (b). Then, due to the caster effect that occurs when the vehicle body 14 tilts, the front wheel 10 turns to a predetermined position in the right direction that is the tilting direction (the position when the steering angle that conforms to the speed and tilt angle is reached). The toy 1 turns to the right and returns to straight running.

When the traveling toy 1 is in the normal traveling state, the front wheel 10 can be rotated until the steering angle is 15 ° as described above. Rotate the front wheel 10 so that the steering angle is enough to break the balance. 9 058225

twenty two

Therefore, the steering angle is not always 15 °. Furthermore, the handle turning angle of the traveling toy 1 that is turning is also a handle turning angle that matches the speed and inclination angle of the vehicle body 14.

If the player continues to tilt and rotate the turning operation unit 122 to the right, the current constantly flows through the solenoid coil 30 of the direction control unit 3 and the magnetic force acts on the magnet 32. That is, a slight force that tries to rotate in the direction opposite to the operation direction continues to work. As a result, the turning angle of the steering wheel is slightly returned from the angle adapted to the speed and inclination angle of the vehicle body 14, so that the force to constantly tilt the vehicle body 14 to the right continues to work and the toy 1 of the traveling toy 1 A right turn is maintained. Conversely, if the tilting operation of the turning operation unit 122 is canceled, the force that worked to rotate the front wheel 10 in the left direction (opposite to the operation / turning direction) is eliminated. After the angle increases and becomes a predetermined turning angle, the inclination angle of the vehicle body 14 and the steering wheel turning angle gradually decrease due to the restoring force of the caster effect, and the traveling toy 1 moves to a stable straight traveling posture. Restored.

When the traveling toy 1 is in the turning traveling state, when the player pushes the drift operation unit 124 of the transmitter 110, the cam drive unit 4 assists the driving operation as shown in FIG. 8 (b). By operating the wheel projecting means 5 and maintaining this operated state, the auxiliary wheel 12 on the right side, which is in the turning inner direction, protrudes to a predetermined position outside the vehicle body 14, and this protruding state is maintained. At the same time, as shown in FIG. 7 (d), the front wheel rotating means 8 is operated by the cam drive unit 4, and this operating state is maintained, so that the front wheel 10 is in a direction opposite to the turning direction. And the second bevel gear 82 is rotated until the rotational angle ω of the second bevel gear 82 reaches 45 ° (the steering angle 0 2 is 30 °), and this rotated state is maintained. As a result, as shown in FIGS. 1, 2, and 9 (c), the traveling toy 1 is a drift in which the vehicle body 14 tilts more than the above-mentioned turning state and the assisting wheel 12 contacts the traveling surface. It will shift to the driving posture.

In addition, when the traveling surface is an inclined surface, when the traveling toy 1 is shifted from the normal traveling posture to the drift traveling posture, the tilting operation may be performed earlier than the operation of the auxiliary wheel holding portion 52. Although this traveling toy 1 has fall prevention bars 16 on both sides of the body 14 Therefore, the traveling toy 1 does not fall down, and after the body 14 tilts and the fall prevention bar 16 is installed on the running surface, the auxiliary wheel holding part 52 is rotated to shift to the drifting running posture. Is possible.

Also, when the toy 1 is in the drift running state, if the player releases the drift operation and the turning operation, the cam drive unit 4 is driven, and the second bevel gear 82 and the pressing cam 50 are in the normal running state. It will rotate to the position. As a result, the auxiliary wheel holding portion 52 is released from the pressing force of the pressing portion 58 of the pressing cam 50, and returns to its original position so as to be in close contact with the vicinity of the vehicle body 14 by the elastic force of the torsion coil spring 56. When the auxiliary wheel holding part 52 returns, the balance of the vehicle body 14 returns to the original state, and the front wheel 10 can be rotated so as to have a steering angle that matches the speed and inclination angle of the vehicle body 14.

Then, after the auxiliary wheel projecting means 5 and the front wheel rotating means 8 return to the initial positions, if the rear wheel 11 is continuously driven by the rear wheel drive unit 2, the traveling toy 1 is 14 will return to the normal driving posture and shift to stable normal driving before drifting again.

When the traveling toy 1 is configured in this way, the traveling toy 1 in a stable traveling state is shifted to the turning traveling posture by the direction control unit 3, and when the traveling toy 1 is in the turning traveling state, the front wheel is rotated. By rotating the front wheel 10 in the direction opposite to the turning direction by means 8, the vehicle body 14 is tilted more than in the turning state, and the assist wheel protruding means 5 is used to project the vehicle body 14 outward in the turning direction. It is possible to shift to the drift driving posture with the wheel 12 in contact with the running surface. That is, the player can easily drift the traveling toy 1 that is running at an arbitrary timing. In addition, the traveling toy 1 can perform drift traveling stably by maintaining the state in which the auxiliary wheel protruding means 5 and the front wheel rotating means 8 are operated.

In addition, the traveling toy 1 sends a control signal for driving the cam drive unit 4 to the cam drive unit 4 in response to a remote operation signal from the transmitter 110 to the control unit 102 of the receiver 100 and the rear wheel. It is preferable that a control signal for executing an operation of increasing the driving force applied to the rear wheel 11 from the drive unit 2 is sent to the rear wheel drive unit 2. As a result, the traveling toy 1 9 058225

twenty four

When shifting from the normal travel posture to the drift travel posture, the cam drive unit 4 for operating the auxiliary wheel protruding means 5 and the front wheel rotating means 8 is driven and rearward based on the control signal from the control unit 102. By executing the operation of increasing the driving force applied from the wheel drive unit 2 to the rear wheel 11, the rear wheel 11 is idled, so that drift traveling can be performed more easily. The traveling toy 1 holds the caster shaft 62 mounted with the upper portion inclined backward at the front end of the vehicle body 14, and holds the front wheel 10 and rotates in the left-right direction with respect to the vehicle body 14 about the caster shaft 62. Since the front fork 7 is arranged in a movable manner, when the toy 1 is in a running state, when the vehicle body 14 is tilted, the support position of the vehicle body 14 is lowered below the center of gravity of the vehicle body 14 by the caster effect. Thus, a force is exerted to push the vehicle body 14 back in the direction opposite to the tilt direction, so that the traveling toy 1 can travel stably.

In addition, the traveling toy 1 is provided with a solenoid coil 30 and a magnet 32 in the direction control unit 3, and a current is passed through the solenoid coil 30 to attract and repel the magnet 32, thereby rotating the front wheel 10. Therefore, by applying a weak control torque to the front fork 7 that slightly breaks the balance of the straight traveling state of the vehicle body 14, the vehicle body 14 can be tilted to make a turn. That is, the direction change reaction can be made sensitive. Further, since the auxiliary wheel projecting means 5 is composed of the auxiliary wheel holding portion 52, the pressing cam 50 that rotates the auxiliary wheel holding portion 52, and an elastic body, the traveling toy 1 is captured only when drifting. The auxiliary wheel holding part 52 can protrude outward from the vehicle body 14 and the auxiliary wheel 12 can be brought into contact with the running surface.When returning to the normal driving posture from drift driving, the auxiliary wheel is driven by the elastic force of the elastic body. By rotating the holding portion 52 to the original position in the vicinity of the vehicle body 14, the vehicle body balance is restored to the original state, and stable running can be performed again by the caster effect.

The present invention is not limited to the above-described embodiments, and can be freely changed and improved without departing from the gist of the invention. For example, the traveling toy 1 may be steerable by rowing the transmitter 110 and the receiver 100 by wire. Further, the traveling toy 1 is not limited to one-by-one, but may be a bicycle simulating a mountain bike or the like, and is not limited to a two-wheeled vehicle, but a three-wheeled motorcycle or a three-wheeled vehicle having wheels on the left and right as rear wheels. PT / JP2009 / 058225

It may be a three-wheeled vehicle such as 25.

The direction control unit 3, which is a mechanism for turning the vehicle body 14, is not limited to the case where the solenoid coil 30 and the magnet 32 are configured as described above, and the connecting rod formed as a rack gear is coiled.
