Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a racing toy in which a running object can run at high speed along a running track under radio control.

(Prior Art) In conventional racing toys, a rail for supplying electricity is laid along a running track, and a running object moves on the running track at high speed while receiving electricity from the rail. Ta.

(Problem to be solved by the invention) However, conventional racing toys are constructed in such a way that the running body runs while receiving electricity from an electricity supply rail laid on the track. When manufacturing the components, it is necessary to lay rails for electricity supply, but the process of laying them is extremely troublesome.

Travel track members are made of hard materials that do not easily deform to prevent the electricity supply rail from bending or shifting its mounting position, and cannot be folded away. In many cases, a plurality of track member elements are connected mechanically and electrically in the longitudinal direction, and are removed and put away after use. It has the disadvantage of being easily broken.

If the power supply rail becomes rusty or has dust attached to it, making electrical contact impossible,
The vehicle may become unable to run.

Since the electric potential is low at an apogee remote from the power feeding point on the power feeding rail, the speed of the traveling body changes at each location on the traveling track member.

There were other problems.

This invention was made to solve the above problems.

(Means for Solving the Problems) In order to solve the above problems, the racing toy according to this invention is equipped with a plurality of running tracks each having a groove-shaped cross section in which a guide section consisting of grooves is formed in the center. a running track member, a pit station provided by forming a branch part of the running track in a part of the running track member, a charging device provided in the pit in station, and a guide part at the branch part. a guided portion comprising a protruding path regulating ridge, and a shaft protrusion that engages with the guide portion to ride over the course regulating ridge at high speed and is regulated at low speed to change the direction of the traveling body; Contact pieces that can be contacted with the contact pieces of the charging device are provided on the bottom of the vehicle body, and a running body is equipped with a power source, an electric motor driven by the power supply, and a receiver, and the running body can be run at high speeds and low speeds in stages. It is characterized by consisting of a radio control transmitter that can give commands to

(Function) With the above configuration, in the racing toy according to this invention, the running body receives commands from the transmitter and is charged and starts operating itself even without a rail for electricity supply as in the past. Not only does the vehicle travel on the traveling track by itself using the electric power of the power source provided, but it also travels reliably along the traveling track member while being guided by the guiding part at the guided part even without a remote-controlled steering mechanism for direction change. becomes.

(Embodiment) Fig. 1 shows a racing toy 1 according to an embodiment of this invention, which includes an endless running track member 10 with a running track 10a formed on the upper surface, a radio control transmitter 20, and an inner part. and a traveling body 30 which is equipped with a power source 60 (FIG. 3) for traveling and travels on the traveling track 10a in response to commands from the transmitter 20.

A part of the running track member 10 serves as a pit station 100.

The traveling track member 10 can be made of a highly flexible and soft material such as polyvinyl chloride and can be integrally molded.
It can be folded and stored, and it is also possible to have a configuration in which a plurality of running track member elements (the running track member 10 is divided into appropriate lengths, not shown) are connected in the longitudinal direction. By doing so, it is possible to separate and store each traveling track member element.

The curved portion 10b of the running track member 10 is supported by struts 11 of different heights so that the inner circumferential side is lower and the outer circumferential side is higher. It is prevented from falling off from the running track member 10 due to centrifugal force.

The running track 10a of the running track member 10 is a two-lane road 12, 13 (the number of lanes may be any number).
Figure 2 shows the running track member 1 in Figure 1.
As shown in an enlarged view of a part of 0, the running track 10a
Both shoulder portions 10c, 10c and center separator portion 10d
protrudes upward in the form of a rib to prevent the traveling body 30 from falling off the traveling track 10a or invading other lanes of the road.

A guide groove 15 is formed on the center line of each lane road 12, 13 as a guide portion 14 that guides the traveling body 30 along each lane road 12, 13. A shaft protrusion 31a as a guided portion 31 shown in FIG. is each lane road 12,
It is now possible to drive along Route 13.

On the other hand, as shown in FIG. 3, the traveling body 30 has driven wheels (front wheels) 32, 32 that are free to rotate, and a receiver 40 (as a block diagram shown in FIG. 6) that captures the signal from the transmitter 20. ), a driving motor 50 that operates in response to the output of the receiver 40;
Drive wheels (rear wheels) 33, 33 driven by;
A battery 60a (two rechargeable batteries in this embodiment) is provided as a power source 60 for supplying electricity to the receiver 40 and the motor 50.

Although it is better to provide the driven wheels (front wheels) 32, 32 so that they can change direction freely, the traveling track 10a in the curved portion 10b is inclined so as to become higher toward the outer circumference as described above, In addition, since the shaft protrusion 31a (FIG. 9) at the lower part of the traveling body 30 is guided by the guide groove 15 and forced to travel in the curved portion 10b, it is not necessary to provide a steering mechanism that can freely change direction. There is no need to employ it, and if the steering mechanism is omitted, the configuration of the traveling body 30 can be simplified accordingly.

The receiver 40 also includes a reproducing section 42 for reproducing the signal from the transmitter 20 received from the receiving antenna 41, as shown in a block diagram in FIG. 6 and as a circuit diagram in FIG. An amplifying section 43 that amplifies the signal reproduced by the reproducing section 42, an integrating circuit 44 that integrates the pulse signal amplified and sent by the amplifying section 43, and an average of the signal voltages integrated by the integrating circuit 44. It is comprised of a motor driver 45 that operates the drive motor 50 at a rotational speed proportional to the voltage, and electricity is supplied from the power source 60 to each of these parts.

Note that the drive wheels 33, 33 are provided by a gear mechanism 70.
(Fig. 3), power is supplied from the motor 50 to enable high-speed running.

On the other hand, the radio control transmitter 20
As shown as a block diagram in FIG. 5 and as a circuit diagram in FIG. and a transmitting section 22 that transmits the pulse signal oscillated by the section 21.

The transmitter 20 is pistol-shaped, as shown in FIG. 4 as a partially cutaway exterior, and is powered by an internal power source (not shown) by sliding a switch 25 that is slidably installed at the top. is on/
In addition, the trigger part 2
By tightening and releasing 6, the resistance value of the variable resistor 23 for changing the oscillation frequency of the pulse generator 21 can be changed, thereby changing the number of pulse signals generated per unit time. It is becoming more and more popular.

By causing the receiver 40 of the traveling body 30 to receive a pulse signal from the transmitter 20 configured as described above, the traveling body 30 can be made to travel, and the unit can be activated by operating the trigger section 26. By changing the number of pulse signals transmitted per time, the rotational speed of the drive motor 50 can be controlled, and thus the traveling speed of the traveling body 30 can be freely changed.

In other words, when the force of gripping the trigger part 26 is relaxed, the spring 27 returns the trigger part 26 to the protruding direction, and the resistance value of the variable resistor 23 for changing the oscillation frequency of the pulse generator 21 changes accordingly. getting smaller,
The number of pulse signal oscillations per unit time decreases, and the integrated value of the voltage by the integrating circuit 44 of the receiver 40 that receives this decreases, and the rotational speed of the drive wheels 33, 33 by the motor 50 decreases, causing the running. The running speed of the body 30 becomes low. Conversely, if you tighten your grip on the trigger part 26, the trigger part 26 will resist the force of the spring 27.
6 is rotated in the retracting direction, and accordingly, the variable resistor 23 for changing the oscillation frequency of the pulse generator 21
As the resistance value increases, the number of pulse signal oscillations per unit time increases, and the receiver 40 that receives this increases.
As the integrated value of the voltage by the integrating circuit 44 increases, the rotational speed of the drive wheels 33, 33 by the motor 50 increases, and the traveling speed of the traveling body 30 increases.

In this way, the transmitter 20 allows the number of pulse signal oscillations per unit time to be controlled by external operation, and the voltage that changes depending on the pulse signal per unit time transmitted from the transmitter 20. The traveling speed of the traveling body 30 can be changed by the receiver 40, which rotates the driving wheels 33, 33 via the motor 50, which rotates at a rotational speed proportional to the average voltage value. After stopping the traveling body (radio control car) 30 at The traveling speed of the traveling body 30 can be changed just by operating the machine 20 side.

In addition, because the running body 30 needs to be made as small as possible, it is not equipped with a steering mechanism that automatically changes direction by radio control, which is normally used in running bodies (radio-controlled cars) 30, etc. The number of points is small and the mechanism is simple, and each electronic component forming the receiver 40 is made as small as possible. In particular, the tuning resonant circuit 46 (FIG. 8) that constitutes the reproducing section 42
The variable inductance coil 47 inside is made as small as possible. By the way, the size of the conventional variable inductance coil is approximately 7mm x 7mm.
The size was approximately 11.5 mm (length x width x height), but in the embodiment of this invention, it was 5 mm x 5 mm x 5.5 mm.
It was made as small as about mm.

Further, the pit station 100 is constructed as follows.

As shown in FIG. 1, the pit-in stations 100 are provided in a shape that protrudes approximately symmetrically on the inside and outside of the running track 10a, and the pit-in station 100 on one side (inside) has a pit-in-house shape. A battery box 150 is installed,
A battery 151 is housed therein as a primary power source for charging.

The driving lane roads 12 and 13 on the pit installation 100 have a straight section 12a and a straight section 12.
A pit-in lane section 12b is formed by branching into a Y-shape at the entrance and merging into a Y-shape at the exit. At the branching part 110 (entrance) and merging part 130 (exit) between the straight lane section 12a and the pit-in lane section 12b,
Branching the traveling body 30 into a straight direction and a pit-in direction,
A guide groove 15 is provided to branch and merge in a Y-shape.

A course regulating protrusion 120 is fixedly provided in the guide groove 15 of the branch portion 110. This course regulating protrusion 120 is connected to the branch point 111 (branch part 1
The first guide strip 121 is arranged in the guide groove 15 a little before the center point of 10) and the V-shaped guide strip 121 is disposed in the guide groove 15 slightly before the center point of the branch point. and a second guide strip 122 disposed in the guide strip 122.

The first guide strip 121 is the guide groove 1
It has approximately the same width as 5, and is low on the front side and gently slopes to become higher as it goes forward, the top part 121a beyond that becomes flat, and the end part beyond that becomes lower as it goes forward. Steep slope and junction 111
It is cut off in front of.

Further, the second guide strip 122 is composed of a first branch portion 122a located in the guide groove 15 for straight running and a second branch portion 122b located in the guide groove 15 for pit-in. . The first branch portion 122a is the guide groove 1 for straight running.
5, the top portion 122c at the front thereof is approximately the same height as the top portion 121a of the first guide strip 121, and the further it goes, the lower it becomes. On the other hand, the second branch portion 122b is
The shaft protrusion 31a of the traveling body 30 is arranged along the end of the pit-in guide groove 15 (the end near the direction of the straight-travel guide groove 15), and the shaft protrusion 31a of the traveling body 30
There is enough space for 5 people to pass through. The second branch portion 122b has an inclined portion 1 at its terminal end.
Except for 22d, the height is approximately the same as the height of the top portion 122a of the first branch portion 122a.

Due to the presence of the course regulating protrusion 120 configured in this way, when the traveling body 30 attempts to pass through the branching part 110 from the front direction of the branching part 110 at high speed, the shaft protrusion as the guided part 31 of the traveling body 30 3
The traveling body 30 at that time when the lower end portion of the first guide strip 121 slides up on the inclined portion 121b on the front side of the first guide strip 121.
Due to the inertial force of the shaft protrusion 31a, the first guide strip 12
The second guide strip 12 is separated from the top portion 121a of the first guide strip 12.
Since the vehicle lands on the top portion 122c or the slope portion 122e of the first branch portion 122a of No. 2 and continues as it is, straight traveling is maintained regardless of the branch portion 110. On the other hand, when the traveling body 30 is about to pass through the branching part 110 at low speed, the lower end of the shaft protrusion 31a is connected to the inclined surface 12 on the front side of the first guide strip 121.
Even after climbing 1b, the inertial force acting on the traveling body 30 is small, so the vehicle does not leave the first guide strip 121 and slides down the slope 121c at the end thereof, and is unable to jump over the branch 110. , the second branch portion 122b of the second guide strip 122 in the pit-in guide groove 15 is guided along the side surface of the second branch portion 122b in the pit-in guide groove 15, and the course is changed toward the pit-in station 100.

A charging device 200 as described below is installed at the pit station 100 where the traveling body 30 is guided after changing its course.

A through hole 201 is formed in a part of the lower part of the guide groove 15, so that charging contacts 152 connected to both poles of the battery 151 in the battery box 150 are formed on both left and right sides of the guide groove 15 at the front. , 153 are provided in a protruding manner, and through holes 202, 203 are formed on both the left and right sides of the guide groove 15 further in front of the guide grooves 15.

On the other hand, on the bottom plate 210 attached to the lower side of the pit instation 100, there is a slide plate 220 which is slidable in the front and back directions and is given a return force in the backward direction (toward the near side) by a spring 211. is installed.

The rear side of this slide plate 220 (running body 30
A dogleg-shaped through hole 221 is provided in the center of the front (closer to the front in the direction of movement), and on both sides of the through hole 221, there are rack teeth 222a, 223a on the upper surface, respectively.
Rack members 222 and 223 are provided in a protruding manner, and a rotating shaft 230 is rotatably installed in a fixed position above the rack members 222 and 223. This rotating shaft 23
The rack teeth 222a, 223 are provided at both ends of the
Pinions 231, 232 that are always in mesh with a, and friction wheels 233, 234 that reach approximately the same height as the road surface of the running track 10a via the through holes 202, 203 are fixed. Further, on the bottom plate 210 at a position in front of the slide plate 220, a rotary member 240 is installed at its base so as to be rotatable about a pin 241 as an axis. A pin 242 that is loosely inserted into the dogleg-shaped through hole 221 is vertically provided at the distal end of the rotating member 240, and a pin 242 that is loosely inserted into the dogleg-shaped through hole 221 is installed above the base. A stopper 243 is provided to protrude. When the slide plate 220 is returned to the rear (in the direction of arrow C) by the spring 211, the dogleg-shaped through hole 22
1 meets the pin 242, and the rotating member 240 is rotated back in the counterclockwise direction when looking down from above, and at this time, the stopper 243 is located in the guide groove 15. On the other hand, the slide plate 220
When the member moves forward (in the direction of arrow 2) against the force of the spring 211, the lower part of the dogleg-shaped through hole 221 meets the pin 242, and the rotating member 2
40 rotates clockwise when looking down from above, and at this time, the stopper 243 that was protruding into the guide groove 15 through the through hole 201 comes out of the guide groove 15.

When the traveling body 30 reaches the pit instation 100 configured in this way, the shaft protrusion 31a of the traveling body 30 moves against the stopper 243 of the rotating member 240.
At this time, the driving wheels 33, 33 are riding on the friction wheels 233, 234, and the charged contact pieces 34, 35 of the traveling body 30 are on the traveling track 10a. Upper charging contact piece 1

Then, when the transmitter 2 is properly charged,
When a travel command is issued from 0, the drive wheels 33, 33 rotate, causing the friction wheels 233, 234 to rotate counterclockwise (in the direction of arrow H) in FIG. Then, the pinions 231 and 232 and the rack 222 that meshes with them
a, 223a, the slide plate 220 is advanced, and the dog-shaped through hole 2 moves accordingly.
21 and the pin 242, the rotating member 240 is rotated clockwise in FIG. 9, and the stopper 243 comes out of the guide groove 15. Then, the restraint of the shaft protrusion 31a of the traveling body 30 by the stopper 243 is released, and the traveling body 30 starts traveling forward and leaves the pit instation 100.

Since the racing toy 1 according to this embodiment is configured as described above, the running body 30 is placed on the running track 10a of the running track member 10 with the shaft protrusion 31 fitting into the guide groove 15. By operating the transmitter 20, the traveling body 30 can be brought into either a high speed or low speed state with one channel operation.
If the traveling body 30 runs at a low speed before the branch 110 of
(Fig. 9) and enters the Pitto Station 100, where charging is carried out as described above.
Thereafter, it leaves the pit station 100 again in accordance with the command from the transmitter 20.
However, the traveling body 30 is
If you do not want to lead it into zero, you can just make it pass through the branching part 100 at high speed.

In the above embodiment, the guide portion 14 is connected to the guide groove 1.
5, and the guided portion 31 is configured as the shaft protrusion 31a, but the guide portion 14 is not limited thereto.
may be a rail-shaped guide protrusion (not shown), and the guided portion 31 may be configured as a concave part that is fitted onto the guide protrusion. Further, although a toy car is shown as the running object 30, the present invention is not limited thereto, and may be, for example, a train or a train.

(Effect of the invention) As described above, the racing toy according to the invention includes a running track member on which a running track is formed, a transmitter for radio control, and a power source for running, and receives commands from the transmitter. a traveling body that receives the traveling body and runs on the traveling track, and is provided with a guide portion that guides the traveling body along the traveling track;
Since the traveling body is provided with a guided part that is guided by the guide part, the traveling body can receive commands from the transmitter and receive commands from the transmitter even if there is no rail for electricity supply as in the past. Not only can it self-propel on a running track using the power of its own or charged power source, but it can also move without a steering mechanism for remote control direction change.
In the guided portion, the vehicle reliably travels along the running track member while being guided by the guide portion, and there is no need to lay rails for electricity supply, making it easy to manufacture the running track member.

Since a rail for electricity supply is not required, the running track member can be made of a soft material (eg, polyvinyl chloride, etc.) and can be folded and stored when not in use.

Failures due to poor electrical contact due to connections between running track members are eliminated.

Unlike when installing rails for electricity supply, there is no need to worry about poor electrical connections caused by rust or dust on the rails, and the potential is low at remote points far from the power supply point. This eliminates the inconvenience of slowing down the traveling body.

Since the vehicle can reliably travel along the travel track member while being guided by the guide portion in the guided portion, a remote-controlled steering mechanism for direction change is no longer necessary.
