A traveling toy comprising a wheel, a front wheel rotation mechanism that rotates the front wheel in the left-right direction with respect to the vehicle body, and a rear wheel drive unit that drives the rear wheel, Auxiliary wheels respectively attached to the left and right sides of the vehicle body, and auxiliary wheel protrusion means for causing the auxiliary wheels to protrude outwardly from the vehicle body, the control unit from the transmitter In response to the operation signal, driving is started by driving the rear wheels by the rear wheel driving unit, and when in this driving state, the front wheel turning mechanism is controlled to move the front wheels leftward or rightward. Rotate to shift to turning and When the front wheel turning mechanism is controlled to turn the front wheel to a running posture in which the vehicle body is tilted by turning the front wheel by a predetermined amount in a direction opposite to the turning direction of the turning traveling, the front wheel turning mechanism In cooperation with the control for rotating the front wheel in the direction opposite to the turning direction, the auxiliary wheel protruding means is operated to cause the auxiliary wheel in the direction in which the vehicle body tilts to protrude outward from the vehicle body, and the front wheel Until the auxiliary wheel comes into contact with the running surface while maintaining the rotation state of the front wheel rotated in the direction opposite to the turning direction and the protruding state of the auxiliary wheel in the tilt direction of the vehicle body by the auxiliary wheel protruding means. By executing control for tilting the vehicle body, the vehicle may be configured to shift to a drift traveling posture in which the auxiliary wheel is grounded on the traveling surface.

  The front wheel rotation mechanism is provided separately from the direction control unit that controls the turning direction of the traveling toy by rotating the front wheel in the left-right direction in a normal traveling state, and the front wheel And a front wheel rotating means for rotating the vehicle by a predetermined amount, and the transition to the turning traveling in which the front wheel is rotated leftward or rightward to shift to the turning traveling is executed by controlling the direction control means. When the vehicle is turning, the front wheel turning mechanism is controlled to turn the front wheel to a running posture in which the vehicle body is tilted by turning a predetermined amount in a direction opposite to the turning direction of the turning. The transition to the tilted running posture may be configured to be executed by controlling the front wheel rotating means.

  The transition to the traveling posture in which the vehicle body is tilted works on the vehicle body by controlling the front wheel rotation mechanism to give the movement of rapidly rotating the front wheel leftward or rightward when in the traveling state. It is also possible to use inertial force.

  According to the present invention, auxiliary wheels capable of projecting outward are provided on both sides of the vehicle body of the traveling toy, and the auxiliary wheel on the side in the tilting direction is linked to the operation of shifting the vehicle body to the tilting traveling posture. By shifting the front wheel rotation mechanism that protrudes toward the vehicle body and shifting the vehicle body to the tilted running posture, the tilt angle of the vehicle body is further increased, and the auxiliary wheel shifts to the drifted driving posture that touches the running surface. Therefore, the traveling toy that the player is traveling at an arbitrary timing can be easily drifted. Further, by maintaining the state where the auxiliary wheel protruding means and the front wheel rotating means are operated, drift traveling can be stably performed.

  Then, when shifting to the drift traveling, the rear wheel drive unit applies the rear wheel to the rear wheel in conjunction with the operation of the front wheel rotating means for rotating the front wheel in the direction opposite to the turning direction based on the control signal from the control unit. By performing the operation of increasing the driving force and causing the rear wheels to idle, the drift traveling can be performed more easily.

  When the traveling toy is in a normal traveling state, the caster shaft mounted in an inclined state with the front fork holding the front wheel is disposed so as to be able to rotate in the left-right direction. The traveling toy can be stably driven by the effect.

  Also, if the direction control unit is equipped with a solenoid coil and a magnet, and current is passed through the solenoid coil and the magnet is repelled and attracted to rotate the front wheels, the balance of the straight running state of the vehicle body will be slightly disrupted. By applying a weak control torque to the front fork, the vehicle body can be tilted and run while turning, so the direction change reaction can be made sensitive.

  Furthermore, by providing an elastic body for the auxiliary wheel protruding means, the auxiliary wheel holding part can protrude outward from the vehicle body only when drifting, and the auxiliary wheel can be brought into contact with the running surface. When returning to the posture, the auxiliary wheel holding portion is rotated to the original position by the elastic force of the elastic body to return the vehicle body balance to the original state, and stable running can be performed again by the caster effect.

  Further, if the front wheel turning mechanism is constituted by a direction control unit and a front wheel turning means, the front wheel turning mechanism controls the direction of the front wheel, and during normal running, the direction control unit performs straight traveling or turning running. By controlling and operating the front wheel rotating means in cooperation with the auxiliary wheel protruding means, drift traveling can be performed.

A receiver that responds to a remote operation signal from the transmitter 110, and includes a magnet 32 that generates attraction / repulsion force by a magnetic field generated by 30 and a connecting rod 34 that connects the magnet 32 and the front fork 7. By attracting and repelling the magnet 32 by causing a current to flow through the solenoid coil 30 by the control unit 100, the attraction / repulsion force is transmitted to the front fork 7 via the connecting rod 34, and FIG. As shown in FIG. 6C, the front wheel 10 is configured to be turnable in the left-right direction with respect to the vehicle body 14.

  Further, as shown in FIG. 5, a cam drive unit 4 mounted substantially at the center of the vehicle body 14 is a cam for operating a servo motor 40 as a drive source and a link base 80 in a front wheel rotating means 8 described later. A main shaft 44 provided with the first bevel gear 81 of the first bevel gear 81 and the second bevel gear 82 which are operating portions in the vicinity of the front end, and a plurality of servo motors 40 disposed so as to be able to transmit the driving force to the main shaft 44. The first bevel gear 81 and the second bevel gear 82 of the cam operating unit are meshed so as to be able to transmit rotation between two axes intersecting at an arbitrary angle. As shown in FIG. 7A, the second bevel gear 82 is formed with a pushing portion 83 that pushes the front wheel turning means 8.

  Further, the front wheel turning means 8 incorporated in the front of the center of the vehicle body 14 is provided with 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, the front fork 7, and the link base 80. And a connecting bar 84 for connecting the front fork 7 to the front fork 7. The link base 80 is formed with a fitting portion for fitting the pushing portion 83 of the second bevel gear 82. By driving the cam drive unit 4 in response to a remote operation signal from the transmitter 110, the link base 80 is moved via the speed reduction mechanism 41, the main shaft 44, the first bevel gear 81, and the second bevel gear 82. By rotating, as shown in FIG. 7D, the front fork 7 is configured to be rotatable in the left-right direction around the caster shaft 62.

  As shown in FIGS. 5 and 8 (a), the auxiliary wheel protruding means 5 holds a pair of auxiliary wheels that hold the auxiliary wheel 12 and are disposed so as to be pivotable in the vertical direction with respect to the vehicle body 14. 52, a pressing cam 50 that 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, and an auxiliary wheel holding And a torsion coil spring 56 which is a pair of elastic bodies arranged so as to be capable of urging the portion 52.

  The auxiliary wheel protruding means 5 rotates the main shaft 44 and the pressing cam 50 via the speed reduction mechanism 41 by driving the cam drive unit 4 in response to a remote operation signal from the transmitter 110. Thus, one of the pair of auxiliary wheel holding portions 52 is pressed by the pressing portion 58, and the auxiliary wheel 12 is moved to a predetermined position outside the vehicle body 14 (see FIG. 8B). The auxiliary wheel holding portion 52 is configured to be rotatable so as to protrude to the position in the drift traveling state), and the auxiliary wheel 12 is moved to a predetermined position near the vehicle body 14 (in the normal traveling state) by the elastic force of the torsion coil spring 56. The auxiliary wheel holding portion 52 is configured to be rotatable so as to return to the position).

Then, as shown in FIG. 9A, the traveling toy 1 moves the traveling toy 1 by placing the traveling toy 1 on the traveling surface and driving the rear wheel 11 by the rear wheel driving 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 from the lower side, and a trail is formed with the grounding point of the front wheel 10 being rearward of the caster axis. Therefore, the caster effect adjusted by the synergistic effect of the caster angle and the trail can be generated, and if the vehicle body 14 of the traveling toy 1 is vertical, the front wheel 10 is directed forward and the straight traveling is stabilized. When 14 is tilted, the handle is rotated by the 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, and the grounding point of the front wheel 10 and the rear wheel The traveling line is maintained so as to prevent the traveling toy 1 from toppling by moving the support line of the vehicle body 14 connecting the 11 grounding points below the center of gravity.

  Then, in order to cause the direction control unit 3 to make a turn, the direction control unit 3 sets the front wheel 10 to the vehicle body 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. On the other hand, when the vehicle is slightly rotated in the left direction, a force directed to the right side is applied to the vehicle body 14 due to the inertial force, so that the rotation direction of the front wheel 10 is opposite to that shown in FIG. The vehicle body 14 is tilted to the right, and the caster effect generated by tilting the vehicle body 14 causes the front wheel 10 to be tilted in a predetermined position in the right direction (position when the steering wheel turning angle conforms to the speed and tilt angle). Even if the steering wheel of the direction control unit 3 is slightly turned to the left, 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 by the force of slightly turning the steering wheel of the direction control unit 3 to the left. Without rebuilding the right inclination of the body 14 The right turn is continued and the right turn is continued.

  Further, in the left turn, the vehicle body 14 is tilted to the left by operating the handle so that the front wheel 10 is cut to the right side, and the front wheel 10 is turned to the left so as to turn the handle to the left by a caster effect. By applying a slight force to turn the handle to the right by the direction control unit 3, the angle at which the handle is turned to the left by the caster effect is slightly reduced to maintain the left inclination of the vehicle body 14, and the left turn of the traveling toy 1 is continued. Is.

  Then, when it is desired to shift from the normal traveling straight traveling state or the traveling state of the right turn or the left turn state to the drift travel, first, the direction control unit 3 is controlled to rotate the front wheel 10 slightly to the left, for example. Thus, as shown in FIG. 9 (b), the vehicle shifts to the right turning running posture inclined to the right, and is slightly smaller than the position when the front wheel 10 has reached the predetermined position (the steering angle that matches the speed and the inclination angle). In other words, the traveling toy 1 maintains the right-turning traveling state by maintaining the state of turning to a small steering angle).

  Next, when the traveling toy 1 is in the turning traveling state, the auxiliary driving means 5 is operated by the cam driving unit 4 to maintain the operated state, thereby the right auxiliary wheel that is in the turning inner direction. While maintaining the state in which the 12 protrudes to a predetermined position outside the vehicle body 14 and is protruded, the front wheel turning means 8 is operated to turn the handle toward the left, which is the turning outward direction, and this operated state is maintained. Thus, the state in which the front wheel 10 is rotated to a predetermined position in the left direction, which is the direction opposite to the turning direction, is maintained.

  In this way, when the traveling toy 1 turns the steering wheel while turning, the vehicle body 14 that has been inclined in the turning running state is further inclined as shown in FIGS. 1, 2, and 9C. Therefore, the vehicle body 14 can be shifted to a tilted traveling posture until the auxiliary wheel 12 is brought into contact with the traveling surface.

  Further, the control unit 102 of the receiver 100 mounted on 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 and By forming the control signal for executing the operation of increasing the driving force applied to the rear wheel 11 from the wheel drive unit 2 to the rear wheel drive unit 2, the vehicle body 14 is tilted and the rear wheel 11 is idled. Since the running toy 1 can be operated, it is possible to easily shift to the drift running posture.

  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, The auxiliary wheel holding portion 52 is released from the pressing force of the pressing portion 58 of the pressing cam 50, and the auxiliary wheel holding portion 52 is rotated to the normal traveling state position by the elastic force of the torsion coil spring 56. At this time, the front wheel turning means 8 returns to the normal position, the front wheel 10 can be swung in the left and right directions in accordance with the front and turning, and the balance of the vehicle body 14 is restored to the original state by turning the handle to the inside of the turning. Returning to the above, by continuously driving the rear wheel 11 by the rear wheel drive unit 2, the vehicle body 14 returns to the normal traveling posture by the caster effect, and stable traveling can be performed again.

A receiver having a control unit that performs operation control is mounted, and the receiver is remotely operated when the receiver responds to an operation signal from a wireless transmitter.

  The traveling toy 1 includes a rear wheel drive unit 2 that drives the rear wheel 11, a direction control unit as a front wheel rotation mechanism that controls the rotation of the front wheel 10 in the left-right direction, and a front wheel rotation unit. A direction control unit that rotates the front wheel 10 in the left-right direction with respect to the vehicle body 14 in the normal traveling state, auxiliary wheel protrusion means 5 that protrudes the auxiliary wheel 12 in the left-right direction with respect to the vehicle body 14, and the auxiliary wheel protrusion When the auxiliary wheel 12 protrudes leftward or rightward by means 5 and drift travels, the front wheel 10 protrudes from the auxiliary wheel 12 so that the auxiliary wheel 12 comes into contact with the traveling surface and enters a drifting state. A front wheel rotating means that rotates in the right direction or the left direction, which is the reverse direction, and a cam drive unit that operates the auxiliary wheel protruding means 5 and the front wheel rotating means and maintains the operated state. The control unit of the receiver responding to the operation signal from the transmitter sends a predetermined control signal. By generating and driving the rear wheel drive unit, the direction control unit, and the cam drive unit 4, the vehicle travels straight, turns, and drifts.

  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. The transmitter 110 travels with the power switch 115 and moves forward, stops, reverses, and changes in the horizontal direction. A traveling operation unit 120 and a turning operation unit 122 for instructing the toy 1, a power indicator for displaying the presence / absence of power, an antenna 116 for transmitting radio waves, and a transition to a drift traveling posture Has a drift operation section 124 for instructing the above.

  The drift operation unit 124 is provided 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 (for turning right or turning left). The traveling toy 1 may be shifted to drift traveling by operating the.

  Then, as shown in FIG. 4, the transmitter 110 includes the above-described operation units 120, 122, and 124, a control unit 112 that generates a predetermined signal in accordance with the player's operation, and an encoding sent from the control unit 112. It comprises a transmission circuit 111 that modulates the received signal, an amplifier 118, an antenna 116 that transmits this signal, a power source (not shown), and the like. The receiver 100 also receives a radio signal transmitted from the transmitter 110 via the antenna 106 and demodulates the reception 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, a power source (not shown), and the like. Note that it is preferable that the passive elements of the transmitter circuit 111 and the receiver circuit 101 of the transmitter 110 and the receiver 100 are detachable crystal resonators because the frequency can be changed by the player.

  Here, the cam drive unit 4 operates a front wheel rotation means and an auxiliary wheel protrusion means 5 described later, and includes a rotary potentiometer that detects a rotation angle of a servo motor as a drive source and a main shaft as a drive shaft. It is to be prepared. When the traveling toy 1 drifts, the control unit 102 drives the servo motor and monitors the detection value by the potentiometer, and 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.

  Further, 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 10 Is sent to the cam drive unit 4 to rotate the vehicle in a direction opposite to the turning direction. Thus, for example, if the player performs a drift operation while performing a left turn operation, the servo motor of the cam drive unit 4 so that the front wheel 10 rotates in the right direction (the direction opposite to the turn direction). Will be driven.

  When shifting from straight running to turning, when the lever of the turning operation unit 122 is operated to output a right turning operation signal, the direction control unit 3 turns the front wheel 10 slightly to the left, and the front wheel By turning 10 to the left, the body 14 of the traveling toy 1 is tilted to the right from the vertical straight traveling state, and the handle is cut so that the front wheel 10 is directed to the right by a caster effect described later by the right tilt of the body 14, The traveling toy 1 turns right.

  Then, the drift operation signal is transmitted from the transmitter 110 by operating the drift operation unit 124 while the vehicle body 14 is tilted to the right and turning right, and the drift travel command is transmitted from the control unit 102 of the traveling toy 1 Is output to the cam drive unit 4 and the cam drive unit 4 is actuated to rotate the front wheel 10 to the left opposite to the turning direction by the front wheel turning means 8, in cooperation with the operation of the front wheel turning means 8. The auxiliary wheel protruding means 5 is also operated to cause the auxiliary wheel 12 on the inside of the turn, which is in the inclined direction, to protrude.

  The operation of the drift operation unit 124 is effective only when the lever of the turning operation unit 122 is operated, and the drift operation signal is output, and the drift operation signal is output by an incorrect operation during straight traveling. The traveling toy 1 is prevented from being overturned.

  Thus, by operating the traveling operation unit 120, the driving motor of the rear wheel driving unit 2 can be driven to rotate the rear wheel 11 to cause the traveling toy 1 to travel, and the traveling toy 1 moves straight. By operating the turning operation unit 122 when in the traveling state, the direction control unit 3 can be driven to tilt the traveling toy 1 to perform the turning traveling, and the traveling toy 1 is in the turning traveling state. Occasionally, by operating the drift operation unit 124, the cam drive 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.

Since the other end of the rear wheel cushioning portion 24 is pivotally supported at the rear of the vehicle body 14, the impact received by the rear wheel 7 from the running surface during traveling is caused by the rear wheel holding portion 22 and the rear wheel cushioning portion 24. Will be absorbed.

  Further, the traveling toy 1 has an arm portion 60 integrally formed with a case of a direction control portion 3 described later in front of the upper portion of the vehicle body 14 and protrudes to the front side. 62 is mounted with the upper part of the caster shaft 62 inclined rearward. The traveling toy 1 includes a front fork 7 that holds the front wheel 10 and is pivotable in the left-right direction with respect to the vehicle body 14 around the caster shaft 62. A cylindrical front wheel holding portion 78 that holds the front wheel 10 and a vehicle body support portion 70 that supports an arm portion 60 that is a tip portion of the vehicle body 14 at the upper portion are provided.

  In this way, the caster shaft 62 is set to have a predetermined caster angle with the upper portion of the caster shaft 62 inclined rearward, and a predetermined trail is given to the front wheel 10, so that the caster angle and the trail are synergistic. If the vehicle body 14 of the traveling toy 1 is vertical, the front wheel 10 can be directed forward to stabilize the straight traveling, and when the vehicle body 14 is tilted, the front wheel 10 is directed in the direction in which the vehicle body 14 is inclined. The caster effect is generated, and the caster effect travels so that the front wheel 10 moves in the direction in which the vehicle body 14 is inclined, and the support line of the vehicle body 14 that connects the grounding point of the front wheel 10 and the grounding point of the rear wheel 11 is centered. The traveling can be continued by preventing the traveling toy 1 from falling over by being moved downward.

  The vehicle body support part 70 is formed by integrally forming a pair of upper and lower parallel plates 70a and 70b formed in a substantially triangular shape and a pair of sliding shafts 76. The 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 slidably mounted 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 lower surface of the lower plate 70b and the front wheel holding portion 78 are mounted. By mounting the coil spring 74 on the upper surface of the motor, the vehicle body holding part 70 is supported by the front wheel holding part 78 so as to be swingable in the vertical direction via the pair of coil springs 74. 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 portion of the vehicle body 14, and as shown in FIG. 6 (a), a current is supplied in response to a remote operation signal from the transmitter 110. A flowing solenoid coil 30, a magnet 32 that generates an attractive / repulsive force by a magnetic field generated by the solenoid coil 30, and a connecting rod 34 that connects the magnet 32 and the front fork 7 are provided.

  The solenoid coil 30 is disposed in a substantially front-rear direction so that the central axis of the solenoid coil 30 is close to one sliding shaft 76 of the pair of sliding shafts 76. A cylindrical member is formed so as to protrude forward of the solenoid coil 30 so that the magnet 32 can move slidably in the front-rear direction on the central axis of the solenoid coil 30. A 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, and a U-shaped connecting portion 36 is formed at the tip of the connecting rod 34. The connecting portion 36 is pivotally connected to the sliding shaft 76 of the front roke 7.

  Then, by passing a current 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, as shown in FIG. 6B or FIG. 6C, the magnet By attracting and repelling 32 and moving the magnet 32 forward or backward, the attraction / repulsion force is transmitted to the front fork 7 via the connecting rod 34 and held in the front wheel holding portion 78 of the front fork 7. The front wheel 10 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 steering angle for a drift running described later.

  As shown in FIG. 5, the cam drive unit 4 incorporated in the substantially central part of the vehicle body 14 is a cam operation unit that operates a servo motor 40 as a drive source and a link base 80 of a front wheel rotating means 8 described later. The first bevel gear 81 of the first bevel gear 81 and the second bevel gear 82 are provided near the front end, the main shaft 44 including the potentiometer 130 at the rear end, and the driving force of the servo motor 40 is transmitted to the main shaft 44. And a reduction mechanism 41 composed of a plurality of gear trains that can be arranged, and the first bevel gear 81 and the second bevel gear 82 of the cam operation unit are arranged between two axes intersecting at an arbitrary angle. It is meshed so that rotation can be transmitted. As shown in FIG. 7A, a pushing portion 83 that pushes the front wheel turning means 8 is formed on the upper surface of the second bevel gear 82 arranged in the center front of the vehicle body 14. The pushing portion 83 has a substantially cylindrical shape and has a convex portion provided so 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 includes a link base 80 that is pivoted near the front end in the vehicle body 14 and transmits the force from the pushing portion 83, the front fork 7, the link base 80 and a pair of connecting bars 84 that connect between the lower plate 70b of the vehicle body support 70 that is the upper portion of the front fork 7, and the link base 80 includes a second bevel gear A fitting portion for fitting the pushing portion 83 of 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.

  Therefore, 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 unit 83 are rotated via the speed reduction mechanism 41, the main shaft 44, and the first bevel gear 81. The turning force is transmitted when the convex side surface of the pushing portion 83 and the concave side surface of the fitting portion formed on the link base 80 come into contact with each other, whereby the front wheel rotating means 8 as a link mechanism operates. Thus, the front fork 7 rotates left and right around the caster shaft 62.

Further, as shown in FIGS. 7B and 7C, the fitting portion is arranged so that the link base 80 is rotated until the handle turning angle θ1 reaches 15 ° by the rotation of the front fork 7, for example. 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, even if the above-described direction control unit 3 is driven and the front fork 7 is rotated as shown in FIGS. 6B and 6C, FIGS. 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 θ1 becomes 15 ° or more.

  As shown in FIG. 7 (d), for example, 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 45 °. In this case, the steering angle θ2 is 30 °. The rotation angle ω of the second bevel gear 82 is indirectly detected based on the rotation angle of the main shaft 44 by the potentiometer 130 provided on the main shaft 44, and the control unit 102 receives this detection value and Operation control of the servo motor 40 of the drive unit 4 is executed.

  Specifically, when the traveling toy 1 is in a normal traveling state (straight traveling or turning traveling state), the control unit 102 is fixed and maintained so that the rotation angle ω of the second bevel gear 82 is 0 °. When the servo motor 40 is stopped and the control unit 102 receives the drift travel command, the servo motor 40 is operated until the rotation angle ω reaches 45 °, and the second bevel gear 82 is moved. The servo motor 40 is stopped so that the rotation angle ω is fixed and maintained in a state of 45 °, and when returning from drift traveling, the servo is continued until the rotation angle ω of the second bevel gear 82 becomes 0 ° again. The operation of the servo motor 40 is controlled so that the servo motor 40 is stopped so that the second bevel gear 82 is fixed and maintained when the motor 40 is operated and the rotation angle ω is 0 °.

  As shown in FIGS. 5 and 8A, the auxiliary wheel projecting 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 auxiliary wheels 12. A pair of torsion coil springs 56, and the pressing cam 50 is fixed to the main shaft 44 so as to be rotatable by the cam drive unit 4, and when the main shaft 44 rotates, the auxiliary wheel holding portion A rod-like pressing portion 58 for pressing 52 is provided at the left and right ends of the rear surface. The auxiliary wheel holding portion 52 is substantially L-shaped, holds the auxiliary wheel 12 at one end, is inserted into the vehicle body 14 at the other end, and the upper surface of the inserted portion is the pressing portion of the pressing cam 50. It is arranged so as to be able to come into contact with the lower surface of 58 and to be rotatable in the vertical direction with respect to the vehicle body 14. The torsion coil spring 56 is an elastic body arranged so as to be able to bias the auxiliary wheel holding portion 52, and the auxiliary wheel holding portion 52 is in contact with the inner side surface of the vehicle body 14 and the auxiliary wheel holding portion 52. It is penetrated by the axis | shaft used as the rotation center of.

  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 holds the pair of auxiliary wheels. One auxiliary wheel holding part 52 is pressed among the parts 52, and the auxiliary wheel 12 is protruded to a predetermined position (position in the drift travel state) outside the vehicle body 14 as shown in FIG. 8 (b). If the auxiliary wheel holding portion 52 is rotated, and the cam driving portion 4 is rotated in the reverse direction to return the pressing cam 50 to the original arrangement state, the auxiliary wheel 12 is caused by the elastic force of the torsion coil spring 56. As shown in FIG. 8 (a), the auxiliary wheel holding portion 52 rotates so that the vehicle wheel 14 returns to a predetermined position in the vicinity of the vehicle body 14 (a position in the normal running state). 12 will be restored to its original state.

  The auxiliary wheel projecting means 5 operates so as to interlock with the front wheel rotating means 8 that is driven by the control unit 102 controlling the potentiometer 130 and the servo motor 40. The operation of the front wheel rotating means 8 and the auxiliary wheel protruding means 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 the turning direction is described only in the right direction.
First, as shown in FIG. 9A, the traveling toy 1 is started by placing the traveling toy 1 on the traveling surface and driving the rear wheel 11 by the rear wheel driving unit 2. In this state, the vehicle body 14 is traveling in a vertical state, so if the vehicle body 14 travels straight forward due to the caster effect, and the vehicle body 14 tilts during traveling and the balance between the left and right becomes unbalanced, By moving the front wheel 10 in an inclined direction due to the effect, the front wheel 10 is moved in the direction in which the vehicle body 14 is inclined, and the support line of the vehicle body 14 connecting the ground point of the front wheel 10 and the ground point of the rear wheel 11 is a traveling toy. The vehicle body 14 can be returned to the vertical position by changing the 1 to the inclined direction and moved below the center of gravity of the traveling toy 1 so that the balance of the vehicle body 14 can be maintained, and the vehicle body 14 is in a straight running posture. As a result, stable running can be performed.

  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. The front wheel 10 is slightly rotated in the left direction (that is, the direction opposite to the operation 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. 9B. Then, due to the caster effect that occurs when the vehicle body 14 is tilted, the front wheel 10 is rotated to a predetermined position in the right direction that is the tilting direction (the position when the steering wheel turning angle conforms to the speed and the tilt angle). The traveling toy 1 turns to the right and returns to straight running.

  The front wheel 10 when the traveling toy 1 is in the normal traveling state can be rotated until the handle turning angle reaches 15 ° as described above. Since the front wheel 10 has only to be rotated so that the steering angle is such that the balance is lost, the steering angle is not necessarily 15 °. Further, regarding the steering angle of the traveling toy 1 during turning, the steering angle is adapted to the speed and inclination angle of the vehicle body 14.

  If the player continues to tilt the turning operation unit 122 to the right, a current constantly flows through the solenoid coil 30 of the direction control unit 3 and a magnetic force acts on the magnet 32. 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 that always tries to tilt the vehicle body 14 to the right continues to work. 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 lost, and the steering angle is reduced by the caster effect. Once it becomes large and reaches a predetermined turning angle, the inclination angle and steering angle of the vehicle body 14 gradually decrease due to the restoring force of the caster effect, and the traveling toy 1 is restored to a stable straight traveling posture. .

  When the traveling toy 1 is in a turning traveling state, when the player pushes the drift operation unit 124 of the transmitter 110, the auxiliary wheel is driven by the cam drive unit 4 as shown in FIG. When the projecting means 5 is operated and this operated state is maintained, the right auxiliary wheel 12 which is the turning inner direction projects to a predetermined position outside the vehicle body 14, and this projecting state is maintained, and FIG. As shown in (d), the front wheel turning means 8 is operated by the cam drive unit 4 and the operated state is maintained, so that the front wheel 10 is in the left direction opposite to the turning direction, and The second bevel gear 82 is rotated until the rotation angle ω reaches 45 ° (the handle turning angle θ2 is 30 °), and this rotated state is maintained, so that FIGS. ), The vehicle body 14 tilts more than the above-mentioned turning state, and the auxiliary wheel 12 runs. So that the transition to the drifting attitude that was ground to the surface.

  In addition, when the traveling surface is a slope, 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 unit 52. In this traveling toy 1, since the fall prevention bars 16 are installed on both side surfaces of the vehicle body 14, the running toy 1 will not fall, and after the vehicle body 14 tilts and the fall prevention bar 16 is installed on the running surface. Then, the auxiliary wheel holding part 52 is rotated, and it is possible to shift to the drift traveling posture.

  Further, when the traveling toy 1 is in the drift traveling 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 positions in the normal traveling state. Until the auxiliary wheel holding portion 52 is released from the pressing force of the pressing portion 58 of the pressing cam 50 and returned 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. In addition, 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 have returned to the initial positions in this way, if the rear wheel 11 is continuously driven by the rear wheel driving unit 2, the traveling toy 1 has the caster effect. As a result, the vehicle body 14 returns to the normal traveling posture, and a transition to the stable normal traveling before the drift traveling is performed again.

  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 10 is set to the turning direction by the front wheel rotating means 8. By rotating in the opposite direction, the vehicle body 14 is tilted more than in the turning traveling state, and the auxiliary wheel 12 protruded outward from the vehicle body 14 in the turning direction by the auxiliary wheel protruding means 5 is grounded to the traveling surface, Since it is possible to shift to the drift traveling posture, it is possible to easily drift the traveling toy that the player is traveling at an arbitrary timing. Further, by maintaining the state where the auxiliary wheel protruding means 5 and the front wheel rotating means 8 are operated, the drift traveling can be stably performed.

  Then, the control unit 102 of the receiver 100 sends a control signal for driving the cam drive unit 4 to the cam drive unit 4 in response to the remote operation signal from the transmitter 110, and from the rear wheel drive unit 2 to the rear wheel 11 If the control signal for executing the operation of increasing the driving force applied to the rear wheel drive unit 2 is sent to the rear wheel drive unit 2, when the traveling toy 1 is shifted from the normal traveling posture to the drift traveling posture, the control unit Based on the control signal from 102, the cam drive unit 4 for operating the auxiliary wheel projecting means 5 and the front wheel rotating means 8 is driven and the driving force applied to the rear wheel 11 from the rear wheel drive unit 2 is increased. Thus, drifting can be performed more easily by causing the rear wheel 11 to idle.

  The caster shaft 62 is mounted with the upper portion inclined rearward at the front end of the vehicle body 14, and the front wheel 10 is held, and the caster shaft 62 is centered on the caster shaft 62 so as to be turnable in the left-right direction. By providing the front fork 7, when the traveling toy 1 is in the traveling state, when the vehicle body 14 is tilted, the support position of the vehicle body 14 is moved below the center of gravity of the vehicle body 14 by the caster effect, so that the vehicle body 14 is inclined. On the contrary, a force to push back acts, and the traveling toy 1 can travel stably.

  The direction control unit 3 includes a solenoid coil 30 and a magnet 32. If the front wheel 10 is rotated by passing a current through the solenoid coil 30 and repelling and attracting the magnet 32, the vehicle body 14 travels straight. By applying a weak control torque to the front fork 7 that slightly breaks the balance of the vehicle, the vehicle body 14 can be tilted to make a turning travel, so that the direction change reaction can be made sensitive.

  Further, if the auxiliary wheel protruding means 5 is constituted by the auxiliary wheel holding portion 52, the pressing cam 50 that rotates the auxiliary wheel holding portion 52, and an elastic body, the auxiliary wheel holding portion 52 is provided only when drifting. The auxiliary wheel 12 can be brought into contact with the running surface by projecting outward from the vehicle, and when returning from the drift running to the normal running posture, the auxiliary wheel holding portion 52 is moved to the original position near the vehicle body 14 by the elastic force of the elastic body. The vehicle body balance is returned to the original state by rotating to the position of, and stable running can be performed again by the caster effect.

  And this invention is not limited to the above Example, A change and improvement are possible freely in the range which does not deviate from the summary of invention. For example, the transmitter 110 and the receiver 100 may be steerable by being connected by wire. The traveling toy 1 is not limited to a motorcycle but may be a bicycle simulating a mountain bike or the like, and is not limited to a two-wheeled vehicle, such as a three-wheeled motorcycle or a three-wheeled vehicle having wheels on the left and right as rear wheels. It may be a three-wheeled vehicle.

  The direction control unit 3, which is a mechanism for turning the vehicle body 14, is not limited to the case where the directional control unit 3 is configured by the solenoid coil 30 and the magnet 32 as described above. It is loosely attached to the sliding shaft 76 via the elastic body, and the pinion gear that meshes with the rack gear is driven by the motor so that the front fork 7 is rotated slightly to break the left-right balance of the vehicle body 14 and turn. Various weights such as placing a weight that can move in the left-right direction in the body 14 and moving the weight to the left and right by a motor etc. The swivel mechanism can be adopted.
