  The front wheel and the rear wheel in the connected vehicle toy disclosed in Patent Document 1 are fixed wheels. Therefore, even if the connected vehicle is swung left and right by the coupler formed to be swingable, each connected vehicle slides to the left and right, and the meandering operation cannot be performed smoothly. Further, as disclosed in Patent Document 2, even if the front wheel of the vehicle is used as a turning axle, an inner wheel difference from the rear wheel occurs. Therefore, in the case of having a plurality of connected vehicles, the turning radii of the front-side connected vehicle and the rear-side connected vehicle are different, and it is difficult to smoothly perform meandering.

  An object of the present invention is to provide a connected traveling toy that can be smoothly moved even when a meandering operation is performed.

  A traveling toy according to the present invention includes a coupled vehicle that is towed by a drive vehicle, and the coupled vehicle includes a carriage and a housing provided on the carriage, and the carriage is relative to a running surface.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an external appearance of a connected traveling toy 1 that can travel on a traveling surface without installing a track. The connected traveling toy 1 is a toy imitating a train. The leading vehicle is a driving vehicle 10 simulating a locomotive. Three connected vehicles 30 simulating a passenger car are connected to the rear of the driving vehicle 10. The connected traveling toy 1 is a toy that can travel and steer by wireless communication using a controller 50 (see FIG. 3).

  The driving vehicle 10 is provided with a traveling steering mechanism shown in the block diagram of FIG. The control signal transmitted from the controller 50 is received by the receiver 13. The control signal received by the receiver 13 is sent to the control circuit 14 and sent to the steering unit 15 and the drive unit 16.

  The steering unit 15 is connected to the front wheels 11 of the drive vehicle 10. The front wheels 11 are steered by the steering unit 15 according to the control signal. The steering unit 15 can be configured, for example, by placing two permanent magnets with their magnetic poles reversed and installing an electromagnetic coil between the permanent magnets.

  At this time, the front wheel 11 is connected to a link member, and this link member is connected to a base plate on which each permanent magnet is placed and slidable to the left and right. When a positive current is passed through the electromagnetic coil, the right permanent magnet is attracted to the electromagnetic coil, the left permanent magnet repels the electromagnetic coil, and the driving vehicle 10 turns left so that the front wheels are directed leftward. When a current in the reverse direction is passed through the electromagnetic coil, the front vehicle is turned rightward so that the drive vehicle 10 turns right. An elastic member such as a spring always returns the front wheel 11 to the front center direction, which is the straight traveling direction, and the drive vehicle 10 travels straight when no current flows through the electromagnetic coil.

  FIG. 3 is a perspective view showing the controller 50. The controller 50 is provided with two steering rods 51 and 52, a power switch 53, and a transmitter 17 for transmitting a control signal, imitating an actual train operation. When the power switch 53 is turned on and the steering rods 51 and 52 are operated, a control signal for the traveling steering mechanism of the driving vehicle 10 is transmitted from the transmitter 17 and received by the receiver 13 of the driving vehicle 10.

  The traveling steering of the drive vehicle 10 by the controller 50 can be performed as follows, for example. When turning the connected traveling toy 1 forward, the right steering rod 51 is pushed forward. When turning the connected traveling toy 1 forward, the left steering rod 52 is pushed forward. When the connected traveling toy 1 is moved straight, the two steering rods 51 and 52 are simultaneously pushed forward. When the connected traveling toy 1 is moved backward, the two steering rods 51 and 52 are simultaneously pulled down, and when turning in the reverse direction, one operation rod is pulled down toward the front side. In this way, the driving vehicle 10 of the coupled traveling toy 1 is travel-steered.

The rear rotation shaft 41d is rotatably supported by a through hole 33b provided on the rear side of the carriage 33 and penetrating in the vertical direction. And the rear side link member 39 is being fixed to the upper edge part of the rear side rotating shaft 41d with the screw 38b.

  Flange portions 36e and 41e are formed at the lower ends of the front rotation shaft 36d and the rear rotation shaft 41d, respectively. The upper surfaces of the flange portions 36e and 41e are slidably brought into contact with the lower surface of the carriage 33 around the lower end openings of the through holes 33a and 33b. In this way, the carriage 33 is supported by the flange portions 36e and 41e of the front wheel support member 36 and the rear wheel support member 41.

  The front link member 37 is formed by a base end portion 37a formed in a boss shape and a link portion 37b extending rearward from the base end portion 37a in a long shape. A hole 37a1 through which the screw 38a is inserted is formed in the base end portion 37a. A hole 37a2 into which the end of the front rotation shaft 36d is inserted is formed on the lower surface of the base end 37a. The lower surface of the base end portion 37a and the lower surface of the link portion 37b are formed to be on the same plane. In addition, a hole 37b1 for connecting the rear link member 39 and the front link member 37 is formed at the tip of the link portion 37b.

  The rear link member 39 is formed by a base end portion 39a having a flat upper surface and a hole 39a2 formed in the lower surface, and a link portion 39b extending forward from the base end portion 39a. . A hole 39a1 into which the screw 38b is inserted is formed in the base end 39a. The end of the rear rotation shaft 41d is inserted into the hole 39a2. The upper surface of the base end portion 39a and the upper surface of the link portion 39b are formed to be on the same plane. A pin 39b1 protrudes downward from the tip of the link portion 39b and is inserted into the hole 37b1 of the front link member 37.

  A fixed connecting portion 33 c is fixed at the center of the rear end portion of the carriage 33. The fixed connection portion 33c includes a base portion 33c2 that protrudes rearward from the carriage 33 and a connection pin 33c1 that stands upward from the base portion 33c2. A protrusion 33c3 is formed at the tip of the connecting pin 33c1 so that it does not easily come off when inserted into the connecting hole 36c1.

  A recess 33 d is formed in the center of the carriage 33. The weight member 42 is accommodated in the recess 33d. The weight member 42 is retained by a plate 43 that is screwed to the upper surface of the carriage 33. Further, countersunk holes 33e and 33f through which screws for attaching the housing 34 to the carriage 33 are inserted are provided before and after the carriage 33.

  The front wheel 31 and the rear wheel 32 are housed in a wheel house portion 44 formed on the carriage 33, respectively. In the wheel house portion 44, the lower surface edge 44a of the carriage 33 is formed in a convex curve shape. Accordingly, the front wheel 31 and the rear wheel support member 41 are perpendicular to the traveling surfaces of the front wheel support member 36 and the rear wheel support member 41 while forming a narrow space between the inner surface of the front wheel 31 and the rear wheel 32 and the vertical surface of the wheel house 44 facing the inner surface. Interference between the front wheel 31 and the rear wheel 32 and the vertical surface of the wheel house 44 due to rotation around the axis can be avoided. Thus, by reducing the space between the inner surfaces of the front wheel 31 and the rear wheel 32 and the vertical surface of the opposing wheel house portion 44, dust on the running surface is separated from the inner surfaces of the front wheel 31 and the rear wheel 32. Further, it is possible to reduce the possibility of being caught between the opposing vertical surfaces of the wheel house portions 44.

  When the front wheel support member 36 is swung around the front rotation shaft 36d, the connected vehicle 30 having the carriage 33 formed in this way has a rear wheel support member via the front link member 37 and the rear link member 39. 41 is beaten. For example, when the connected vehicle 30 turns to the right side, the state is as shown in FIGS. Therefore, since the connected vehicle 30 can be smoothly turned around, the connected traveling toy 1 can perform a smooth meandering operation. And since the weight member 42 is provided in the connection vehicle 30, it will prevent falling down at the time of meandering driving | operation.

  That is, in the connected vehicle 30, the turning direction of the front wheel 31 and the turning direction of the rear wheel 32 are opposite to each other, so that there is no difference between the inner wheels and the rear end of the connected vehicle 30 is not caught inside. Therefore, since the connected traveling toy 1 can turn the rear connected vehicle 30 along the same locus as the front connected vehicle 30, it can be turned in the same manner as when traveling on the rail.

  Furthermore, since the connecting vehicle 30 has the front connecting portion as the movable connecting portion 36c provided on the front wheel support member 36 and the rear connecting portion as the fixed connecting portion 33c, the rotation angle of the front wheel support member 36 is forward. The rotation angle of the rear wheel support member 41 is not affected by the rear vehicle. Therefore, an excessive force is not applied to the rear wheel support member 41.

  In the example according to the present embodiment, the front link member 37 and the rear link member 39 are formed to have a uniform length so that the steering angles of the front wheels 31 and the rear wheels 32 are the same in the opposite directions. Although formed, the front link member 37 may be shortened and the rear link member 39 may be lengthened to make the steering angle of the rear wheel 32 smaller than the steering angle of the front wheel 31.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by this embodiment, It can implement with a various form. For example, the present invention can be implemented if the number of the connected vehicles 30 towed by the drive vehicle 10 is one or more. In addition, among some of the plurality of connected vehicles towed by the drive vehicle 10, some of the connected vehicles are not provided with support members that support the front and rear wheels, and are not connected to the traveling surface. You can also. However, in all vehicles, it is preferable to use the connected vehicle 30 according to the present invention.
