  The present invention relates to a railway vehicle toy.

Conventionally, a toy vehicle is provided with a wheel having a flange inside a wheel main portion constituting a tread surface, and a railway vehicle toy that travels on a road surface on a rail head using the flange as a guide is known (for example, a patent). Reference 1).
Japanese Patent Laid-Open No. 2000-325684 (see FIGS. 1 and 2)

In the railway vehicle toy as disclosed in Patent Document 1, the toy vehicle only travels on the track determined by the rail. Therefore, particularly when the length of the track is short, it becomes monotonous and lacks preference. There is. Therefore, some users may travel on the floor without a rail.
However, if the front wheel has a flange, when trying to run the toy vehicle on the floor, only the outer periphery of the flange contacts the ground, so the ground contact area is small, and the entire front wheel is made of hard plastic. Easy to do. In this case, if the front wheel of the leading vehicle slips, the entire toy vehicle travels in an unexpected direction, and there is a problem that playability is poor.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a railcar toy that is easy to play when traveling on the floor as well as on the rail.

  The first means is a railway vehicle toy provided with a toy vehicle capable of self-propelled on two rails, wherein the leading vehicle of the toy vehicle has a wheel main portion constituting a tread surface and a diameter larger than that of the wheel main portion. The toy is provided with a front wheel in which a flange is integrally formed of hard plastic or metal and a rubber part is formed on the outer periphery of the flange. Here, the self-propelled means that the toy vehicle has a power source and runs with its own power without being pushed. It may be a self-propelled type, and is not limited to being remotely controlled by an external controller, and may be one that travels without remote control.

  As a second means, in the first means, a rubber ring is fitted to the outer periphery of the flange as the rubber portion, and the outer surface of the rubber ring is inward of the outer sliding surface of the flange. It is characterized by being located.

  The third means is characterized in that, in the first or second means, the leading vehicle includes driving wheels behind the front wheels, and the driving wheels are made of rubber.

  According to a fourth means, in the third means, the front wheel is a steering wheel, and is provided in the toy vehicle, a controller for performing rotation control of the driving wheel and steering control of the steering wheel by remote control. And a steering device that changes the direction of the steered wheels by the steering control. The steering device only needs to change the direction of the steering wheel, and a mechanism for keeping the steering wheel in a neutral position in a normal state is not necessarily required.

According to the first to fourth means, since the leading vehicle of the toy vehicle includes the front wheel having the rubber portion formed on the outer periphery of the flange, even when the toy vehicle is driven on a floor surface without a rail or the like. The toy vehicle can be driven in the intended direction.
In particular, the effect is significant when the front wheels of the leading vehicle change direction from side to side depending on the state of the rails.

  According to the second means, since the outer surface of the rubber ring is located inward of the sliding surface outside the flange, the rubber ring of the front wheel slides on the rail when the toy vehicle is driven on the rail. Since it does not move, it is possible to prevent the front wheels from riding on the rail, particularly on the curved rail, and to prevent derailment.

  According to the third means, since the driving wheel is made of rubber, the gripping force when traveling on a floor surface without a rail or the like is increased, so that traveling performance is improved.

  According to the fourth means, since the front wheels are steered by the controller, the traveling direction of the toy vehicle can be arbitrarily controlled.

A railcar toy according to an embodiment of the present invention will be described below with reference to the drawings.

  As illustrated in FIGS. 1 and 2, the toy vehicle 1 of the railway vehicle toy according to the embodiment can travel on the rail 10 and can travel on the floor or the like. This railway vehicle toy includes a rail 10 and a toy vehicle 1. The toy vehicle 1 is provided with a drive device 20, a steering device 30, and the like.

  The rail 10 used in the embodiment is a T-shaped rail. As shown in FIG. 6, the rail 10 includes a head 10 a having a road surface 11 and a substantially rectangular cross section, and the head 10 a. Are formed in a substantially T-shape by an abdomen 10b that supports the center of the bottom of the abdomen and a bottom 10c that extends in the width direction from the base end of the abdomen 10b.

As shown in FIGS. 2 and 3, the drive device 20 provided in the toy vehicle 1 includes a motor 21, a reduction gear train 22, drive wheels 2, and the like.
A worm 22 a is provided on the drive shaft 21 a of the motor 21. The power of the worm 22a is transmitted to the gear 22e of the drive wheel shaft 2a via the worm wheel 22b and a plurality of other gears 22c and 22d to drive the drive wheel 2.

The drive wheel 2 is made of rubber. The reason for using rubber is to improve the grip when traveling on a floor surface without rails.
The drive wheel 2 includes a wheel main portion 3 having a tapered tread surface 2 b and a large-diameter flange 4 formed at the inner end of the wheel main portion 3. The driving wheel 2 has a tread surface 2b rolled on a road surface 11 on the head portion 10a of the rail 10 with the outer side of the flange 4 serving as a guide surface (sliding surface) that slides on the inner surface of the head portion 10a of the rail 10. .

As shown in FIGS. 2 and 4, the steering device 30 provided in the toy vehicle 1 includes two coils 31 and 32 and one permanent magnet 33. The coils 31 and 32 are operated by a coil energization circuit 37 as will be described later.
The permanent magnet 33 is held at one end of the holder 34. A shaft 34 a extending downward is formed at the other end of the holder 34. A circular recess 34b is formed on the upper surface of the shaft 34a, and a non-circular, for example, rectangular recess 34c is formed on the lower surface. And the hole 34d is formed in the partition of the recessed parts 34b and 34c. The shaft 34a of the holder 34 is inserted into a hole 1b formed in the bottom plate 1a of the toy vehicle 1 and is supported rotatably.

  On the other hand, the shaft 5a of the steering wheel 5 is rotatably supported by an inverted T-shaped bearing 35. A convex portion 35b having a shape corresponding to the concave portion 34c of the holder 34 is formed on the upper end portion of the bracket portion 35a erected upward from the center of the bearing 35, and a pin 35c is erected on the upper end surface. .

  And the pin 35c of the bearing 35 is inserted in the hole 34d of the holder 34, and the convex part 35b is inserted in the recessed part 34c. Therefore, in this steering device 30, when the shaft 34a of the holder 34 is rotated, the bearing 35 is rotated integrally therewith, and the steering wheel 5 is thereby steered.

  The steering wheel 5 has a steering wheel body made of hard plastic or metal. As shown in FIGS. 5 and 6, the steered wheel main body includes a wheel main portion 6 having the same tapered tread surface 5 b as that of the drive wheel 2, and the inner side of the wheel main portion 6 than the wheel main portion 6. A flange 7 having a large diameter and a diameter smaller than the flange 4 of the drive wheel 2 is provided. The steered wheel 5 is rolled on the road surface 11 on the tread surface 5b on the head portion 10a of the rail 10 as a guide surface (sliding surface) whose flange 7 is in sliding contact with the inner surface of the head portion 10a of the rail 10.

  An annular rib 7 a is formed on the flange 7 of the steering wheel 5 at the center in the circumferential width direction. A rubber ring 8A is attached to the rib 7a. An annular groove 8a is formed at the center in the width direction of the inner peripheral surface of the rubber ring 8A, and the annular groove 8a is fitted to the annular rib 7a for positioning. Further, the thickness of the rubber ring 8 </ b> A is formed to be thinner than the thickness of the flange 7. Therefore, the outer surface of the rubber ring 8A is located inward from the outer surface of the flange 7 by a distance L0 (see FIG. 6). This distance L0 is set so that the outer surface of the rubber ring 8A is positioned inward of the outer surface of the flange 7 in consideration of manufacturing errors of the annular groove 8a of the rubber ring 8A and the annular rib 7a of the flange 7. Has been. Further, in this steered wheel 5, the height H0 of the flange 7 is set larger than the height H1 of the head 10a of the rail 10.

As shown in FIG. 2, the coils 31 and 32 provided in the toy vehicle 1 are installed on the upper frame 1 c of the toy vehicle 1 so as to be positioned on the left and right with the center in the width direction of the toy vehicle 1 as the center. The coils 31 and 32 are arranged so that their end faces are parallel to the magnetic pole surface of the permanent magnet 33.
The left and right coils 31 and 32 are connected in series to a power source (battery) 36 to constitute a coil energization circuit 37. The left and right coils 31 and 32 are configured such that the polarities on the side facing the end face of the permanent magnet 33 are different on the left and right. The coil energization circuit 37 is energized by a coil energization control unit 47b of the control unit 47 described later. For example, when the left and right coils 31, 32 are energized, an attractive force acts between one coil 31 and the permanent magnet 33, and a repulsive force acts between the other coil 32 and the permanent magnet 33, The holder 34 rotates leftward in the figure, and the steering wheel 5 is directed rightward. In order to change the rotation direction of the holder 34, the direction of the current flowing in the coils 31 and 32 may be changed by the coil energization control unit 47b.
Further, an iron material 33 a is installed between the coils 31 and 32. When the coils 31 and 32 are not energized, the steering wheel 5 maintains a neutral position that is not biased to the left or right by the attractive force acting between the iron material 33a and the permanent magnet 33. This iron material 33a also constitutes a part of the steering device 30 together with the coils 31, 32, the permanent magnet 33, and the like. Instead of the iron material 33a, a spring that holds the steered wheels 5 in a neutral position may be provided.

As shown in FIG. 1, this railway vehicle toy includes an infrared controller 41 for performing a remote operation.
The controller 41 includes a traveling handle 42 for operating the driving device 20 to move the toy vehicle 1 forward and backward, and a steering handle 43 for operating the steering device 30 to set the traveling direction of the toy vehicle 1. In response to the steering operation, an infrared traveling / steering command signal is emitted from the infrared light emitting element 44.
On the other hand, in the toy vehicle 1, as shown in FIG. 1, an infrared light receiving element 45 that receives a traveling / steering command signal transmitted from the light emitting element 44 of the controller 41 is disposed on the substrate 46. The travel / steering command signal received by the light receiving element 45 is input to the control unit 47 of the board 46. As shown in FIG. 8, the control unit 47 includes a motor energization control unit 47a and a coil energization control unit 47b. The control unit 47 supplies power to the motor energization circuit 48 and the coil energization circuit 37 based on the travel command signal and the steering command signal received by the light receiving element 45, and forward / reverse rotation of the motor 21 and the left and right of the steering wheel 5. Steer direction. For example, the toy vehicle 1 is steered by operating the steering handle 43 to the left and right while tilting the traveling handle 42 forward and operating it forward.

According to the railway vehicle toy, when the toy vehicle 1 travels on the floor or the like, the toy vehicle 1 can be advanced in a desired direction by the steering device 30, Since sufficient frictional resistance is provided by the rubber ring 8A, reliable steering can be performed.
Further, when the toy vehicle 1 travels on the rail 10, the rubber ring 8A does not come into contact with the head 10a of the rail 10, so that smooth travel can be performed without increasing the frictional resistance. .

Finally, the reason why the driving wheels 2 and the steering wheels 5 are different in configuration will be described. That is, the drive wheel 2 is entirely made of rubber, while the steering wheel 5 is mainly made of hard plastic, and a rubber ring 8A is fitted to the flange 7.
This is because when the entire steered wheel 5 is made of rubber, especially when moving from a straight rail to a curvilinear rail, the leading vehicle tries to continue straight running, so the sliding contact between the steered wheel 5 and the rail While the main body is formed of hard plastic because the steerable wheels 5 can easily ride on the rails, the direction of the steerable wheels 5 must be changed when traveling on a floor surface without rails. The rubber ring 8A is fitted to the flange 7 because the steering wheel 5 easily slips when it is grounded at the plastic part.
On the other hand, when the driving wheel 2 moves from the straight rail to the curved rail, the leading vehicle has already changed its direction due to the action of the steering wheel 5, so that the sliding contact between the driving wheel 5 and the rail occurs. However, since it is difficult to get on the rail and it is necessary to improve the grip performance to improve the running performance, the whole is made of rubber.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the summary.
For example, in the steering wheel 5 of the above embodiment, the rubber ring 8A is positioned and attached to the flange 7 by the annular rib 7a formed on the peripheral surface of the flange 7. However, as shown in FIG. A groove 7b may be formed, and the rubber ring 8B may be positioned and inserted into the annular groove 7b.
Moreover, in the said embodiment, although the taper was formed in the wheel main parts 3 and 6, the wheel main parts 3 and 6 may be cylindrical.
