  By the way, in the traveling toy disclosed in the above-mentioned prior art document, it is a method of traveling according to the course of the traveling path by the attractive force between the magnet of the traveling path and the magnet attached to the rear surface of the chassis of the traveling toy. Since the attractive force between the magnets always acts directly on the traveling vehicle body during traveling, high-speed traveling cannot be performed, and there is a possibility that the attractive force may stop during low-speed traveling.

  In addition, since there is no front wheel and steering is performed only by the attractive force of the ball bearing and the magnet on the road, there is a possibility that the ball bearing may go out of the magnetic line of the magnet and get off the course when the running speed is high In addition, since there is no front wheel, there is a problem that the frictional resistance at the time of traveling is large and high-speed traveling cannot be performed and smooth movement is impossible, so that the appearance at the time of traveling is not good.

  The present invention is intended to solve the above-described problems. The object of the present invention is to attach a magnetic wire to the traveling road along the course, attach a magnet to the steering portion of the front wheel, and connect the magnet and the wire. The front wheels are steered by shifting the tie rods in the left and right directions by the suction force of the sword, so that the following ability to the wire is good and the curve with a small radius does not deviate from the track. Is something that can be done.

  Moreover, in the case of remote operation, since it can be operated only by a one-channel pilot and receiver for controlling the driving force, the cost can be reduced, and it has been used for a conventional traveling toy for remote operation. Control parts such as a servo motor for steering are not required, and it can be compactly designed, so it can be applied to a very small die-cast model car for decoration even when selecting the body when actually running as a running toy. It is supposed to provide running toys that can be.

  The traveling toy according to the present invention achieves the above-described object, and the means of claim 1 includes a tie rod that shifts in the left-right direction with respect to the chassis to control steering of the front wheels, and at least one course on the traveling path. A magnet that shifts by an attractive force with the track made of a magnetic material wired to the track and shifts the front wheel in the track direction via the tie rod, a motor that drives the rear wheel, and a battery that drives the motor It is characterized by comprising.

  According to a second aspect of the present invention, in the first aspect, the magnet is attached to the tie rod.

  According to a third aspect of the present invention, in the first aspect, the magnet is attached to one end of a link pivotally supported by the chassis, and the other end of the link is pivotally supported by the tie rod. It is characterized by.

  According to a fourth aspect of the present invention, in the above-described second or third aspect, the magnet attached to the tie rod or the link is attached so as to be positioned in the vicinity of the axle of the front wheel.

  According to a fifth aspect of the present invention, in the first aspect, a magnetic body for returning the magnet from the left-right direction to the center position is attached to the fixing portion at a position facing the magnet for shifting the tie rod in the left-right direction. It is characterized by that.

  According to a sixth aspect of the present invention, in the above-described first aspect, the magnet having one end fixed to the fixing portion at a position facing the tie rod and the other end locked to the tie rod is returned from the lateral direction to the center position. It is characterized in that an elastic wire is attached.

  According to a seventh aspect of the present invention, the receiver according to the first aspect is provided with a receiver for driving the rotational speed of the motor by remote control.

  The means of claim 8 attaches one of elastic plates acting as a suspension to at least one of the front wheel side having the tie rod or the rear wheel side having the motor in the first claim. At least the front wheel side or the rear wheel side is attached to the other end of the elastic plate.

  As described above, the present invention has a structure in which a track made of a magnetic material wired on a course in a running road and a tie rod is shifted in the left-right direction by a magnet that is moved in the left-right direction by an attractive force with the track to steer the front wheels. Therefore, driving the rear wheels, which are the driving wheels, causes the vehicle to travel along the track. Therefore, steering is unnecessary and even a small child can play.

  In addition, by attaching the magnet attached to the tie rod or the link so as to be positioned in the vicinity of the axle of the front wheel, it is possible to prevent the rear wheel side chassis from floating due to the attractive force of the track and the magnet, Stable traveling is possible even at high speeds.

  Further, a tie rod or a magnetic body for generating an attractive force with the magnet for returning the magnet from the left-right direction to the center position is attached to a fixed portion at a position facing the magnet attached to the link or the tie rod. Since the elastic wire is engaged with the magnet so that the magnet returns to the center position, the front wheel does not shake in the left-right direction during straight traveling, and stable straight traveling is possible.

  In addition, by attaching a receiver that drives the rotational speed of the motor by remote operation, even if the traveling toy is driven by remote operation, it is not necessary to steer the front wheels, so traveling control can be performed only by speed control, You can enjoy games similar to conventional remote controls.

  Further, one of the elastic plates acting as a suspension is attached to at least one of the front wheel side having the tie rod and the rear wheel side having the motor with respect to the chassis, and at least the front wheel side or the rear wheel side is attached to the other end of the elastic plate. As a result, the bottom plate of the die cast figurine model car can be improved to make the traveling toy of the present invention. Therefore, the popular figurine die cast model car that is commercially available can actually be run. It has effects such as being able to.

It is a top view which shows a part of traveling path which enabled the course change of the traveling toy.

Next, examples of the traveling toy according to the present invention will be described.
1 to 3 show a first embodiment, and A is an automobile toy equipped with a die-cast body. A general die-cast car toy is manufactured as an ornament for ornamental purposes, so it can be run by pushing with a hand, but it is not self-propelled.

  Therefore, in the present invention, a magnet is attached to the tie rod for steering the front wheel to the automobile toy A to which such a die-cast body is attached, and the magnet and the magnetic body formed on the traveling path B shown in FIGS. Steering is performed by moving the tie rod in the left-right direction by the suction force with the track B3, and a motor is attached to the rear wheel, and a receiver (not shown) is mounted to control the drive of the motor by remote control. Thus, the vehicle is improved so as to be able to travel along the track B3 of the travel path B.

Details of the structure will be described below.
1 is a chassis in which the body 2 of the automobile toy A to which the body made of die-casting shown in FIG. It is the Example at the time of creating newly, without using a baseplate.

  A support member 3 protruding in the left-right direction is formed in front of the chassis 1, a steering member 4 is pivotally supported on the support member 3, and a front wheel 5 is rotatable on the steering member 4. It is pivotally supported. Further, a tie rod 6 is attached to the steering member 4, and a cylindrical fitting hole 6 a is formed at the center position in the longitudinal direction of the tie rod 6. And the magnet 7 is engage | inserted by this fitting hole 6a, and is fixed with the adhesive agent etc.

  Therefore, when the magnet 7 moves in the left-right direction, the tie rod 6 moves in the left-right direction, and the front wheel 5 is steered. The lower surface of the magnet 7 is fixed in the fitting hole 6a so as to maintain a certain distance from a road surface of a traveling path B described later through a hole 1d opened in the chassis 1.

  On the other hand, a rear wheel 8, which is a driving wheel, is supported by a rotating shaft (not shown) behind the chassis 1, and the rotating shaft is connected to a motor 10 via a speed reducer 9. The motor 10 is rotationally controlled by a receiver (not shown) attached to the chassis 1. A battery which is a power source for the receiver and the motor 10 (not shown) is housed in the center of the chassis 1.

Next, the configuration of the traveling path B for traveling the traveling toy having the above-described configuration will be described with reference to FIGS. 9 and 10.
The runway B is a player's preference by connecting a large number of straight, S-shaped, and U-shaped pieces B1 made by synthetic resin injection molding at connecting portions B2 formed at both ends of each piece B1. It is structured to create a driving course.

  As shown in FIG. 9, a protrusion B4 for fitting and fixing a magnetic line B3 is formed on the back surface of each piece B1. As a means for attaching the track B3 to each piece B1, the running path B may be molded at the time of injection molding, and various attachment methods such as fixing to the back side or the front side of each piece with an adhesive. Conceivable. Each piece B1 shown in the figure has two lanes as the traveling lane, but may be one lane or two or more lanes.

  After such a large number of pieces B1 are connected to form a desired course, the above-described automobile toy is placed on one of the courses. At this time, it is placed at a position where the attractive force between the line B3 and the magnet 7 acts.

  In this state, when the operation knob such as a lever for driving the motor 10 in the transmitter is operated, a motor drive signal is transmitted from the transmitter. A forward signal is output and the motor 10 starts rotating.

  When the car toy starts running, the magnet 7 is positioned in the center on the straight course due to the attractive force with the track B3, so the tie rod 6 does not steer the front wheel 5 at the position shown in FIG. It becomes a state.

  Further, when the toy car runs on a U-shaped or S-shaped course, the magnet 7 shifts to the left or right by the attractive force of the track B 3, so that the tie rod 6 to which the magnet 7 is attached is also attached to the magnet 7. Shift left or right by transition. The front wheel 5 is steered by the displacement of the tie rod 6, and the traveling toy travels along the course.

  In the above-described automobile toy, the case where the receiver is mounted and the drive of the motor 10 is controlled by remote operation has been described. However, the traveling toy of the present invention is not necessarily driven by remote operation. By driving the motor by turning on the switch equipped in the above, it is possible to guide and run with the attractive force of the magnet 7 and the track B3 as described above.

  In the above-described automobile toy, since the tie rod 6 is in a free state in the left-right direction, the magnet 7 is controlled to be in the center position by the attractive force between the magnet 7 and the track B3 when the course is a straight line. However, when traveling at high speed, there is a possibility that the front wheel 5 may swing in the left-right direction due to friction with the travel path B.

  Therefore, as shown in FIG. 4A, a block-like magnetic body 11 is attached to the chassis 1 facing the magnet 7 in the center position, and the magnet 7 is centered by the attractive force between the magnet 7 and the magnetic body 11. Return to position. Accordingly, since the magnet 7 always maintains the center position, the tie rod 6 controls the front wheel 5 so that the front wheel 5 is in the straight traveling state. I was able to run.

  If the attractive force between the magnet 7 and the magnetic body 11 becomes too strong, the tie rod 6 may be in a fixed state and cannot travel on the curve. Therefore, it is necessary to adjust the distance between the magnet 7 and the magnetic body 11 so that the front wheels do not swing in the left-right direction when traveling straight and the magnet can follow the track B3 when traveling on a curve. is there.

  4B, instead of the magnetic body 11, one end of a pair of elastic wires 12 is fixed to the fixing portion facing the tie rod 6, that is, the chassis 1, and the other end of the elastic member 12 is connected to the tie rod. 6 so that the elastic wire 12 controls the tie rod 6 to be in a straight traveling state in the same manner as the magnet 7 so that the front wheel does not swing in the left-right direction during the straight traveling, and a stable straight traveling can be performed. Yes.

  The spring force of the elastic wire 12 is the same as in the case of the magnetic body 11 described above, the spring force does not act when traveling straight and the front wheel does not swing left and right, and the magnet can follow the track B3 when traveling on a curve. It is necessary to make such a spring force.

  In the above-described automobile toy, since the magnet 7 attached to the tie rod 6 is attached at a position in front of the axle of the front wheel 5, the center of gravity becomes forward due to the attractive force between the magnet 7 and the track B1, There is a possibility that the rear wheel 8 side floats when traveling at high speed, and the rear wheel 8 side floats and swings in the left-right direction when traveling on a curve. In this case, a weight weight or the like can be arranged on the rear wheel side to deal with it.

  On the other hand, as shown in FIGS. 5 (a) and 5 (b), a fitting hole 6a for attaching the magnet 7 formed on the tie rod 6 is formed to extend rearward at least from the axle of the front wheel via the extension 6b. To move the magnet's attraction center point behind the front wheel.

  Since the magnet attraction center point moves rearward from the front wheel in this way, the rear wheel 8 does not float even if the attraction force between the magnet 7 and the track B1 is strong. Even during traveling, the rear wheel 8 side does not float, and stable traveling is possible.

  In the above-described automobile toy, the case where the magnet 7 is attached to the central portion in the longitudinal direction of the tie rod 6 or attached to the extension portion 6b extending from the tie rod 6 is shown, but as shown in FIG. The center portion of the tie rod 6 is pivotally supported by the chassis 1, a fitting hole 11 a for fitting and fixing the magnet 7 is formed at one end of the link 11, and the other end 11 b is pivotally supported by the longitudinal center portion of the tie rod 6. There may be.

  With such a configuration, when the magnet 7 is attracted by the attraction force between the magnet 7 and the line B3, the link 11 is rotated around the center portion, so that the other end 11b of the link 11 is pivotally supported. The tie rod 6 is shifted in the left-right direction. Accordingly, the front wheel 5 attached to the tie rod 6 is steered and the toy car turns, and the toy car is guided along the track B3 and travels along the course.

  The above-described automobile toy is an embodiment in which the chassis 1 is newly created without using the bottom plate simulating the chassis in the diecast figurine model car. The automobile shown in FIGS. The toy is an embodiment in which a part of the bottom plate of the above-mentioned die cast figurine model car is used.

  In this embodiment, the bottom plate at the center of the bottom plate simulating a chassis in a die cast figurine model car is used for the chassis 1a, and the tie rod 6 having the magnet 7 and the tie rod 6 in front of the chassis 1a. The front chassis 1b to which the front wheel 5 to be steered is attached is screwed, and the rear chassis 1c to which the rear wheel 8, the speed reducer 9 and the motor 10 are attached is located behind the chassis 1a via an elastic plate 1f. Screwed.

  In the automobile toy configured as described above, the front chassis 1b and the rear chassis 1c are attached by attaching the front chassis 1b and the rear chassis 1c using a part of the bottom plate of the die cast figurine model car. The present invention can be applied to die cast automobile toys having other approximate dimensions, and therefore, cost can be reduced.

  Moreover, since the role as a suspension can be given by attaching the connection of the rear side chassis 1c and the chassis 1a via the elastic board 1f, the stability of driving | running | working is acquired. Similar stability can be obtained by attaching the front chassis 1b to the chassis 1a via an elastic plate.

  7 and 8, the magnetic body 11 and the elastic wire 12 shown in FIG. 4 and the magnet 7 shown in FIG. 5 are arranged behind the extension 6b so that the attraction center point of the magnet is behind the front wheel. Although the configuration to move to is not disclosed, it is desirable to have the same configuration also in this embodiment.

  Moreover, although all the above-mentioned Examples demonstrated what improved the figurine model car made from die-casting, it is not limited to what is applied to the toy car made from die-casting.

  The travel path B described above travels only along the track B1 provided on one course, but the travel path B in FIG. 11 travels from one course to another course. An example of a road is shown.

  11 is provided with three basic courses, and each course has a track B3. In FIG. 11, the branch line B3a is a line for guiding from the outer course to the inner course, and the branch line B3b is a line for guiding from the inner course to the outer course. is there.

  Next, the operation when changing the course will be described. When the speed of the car toy running along the outer course track B3 on the left side of the inverted U-shape in FIG. Since it is guided along the track B3a, the track is changed to the track in the center course, and the course is changed. Further, when the speed is high, the magnet 7 of the toy car is guided by the track on the extension line of the traveling course that is currently traveling by inertia due to inertia without being guided by the track B3a.

  In addition, the toy car traveling on the center course goes straight because the first branch lines B3a and B3b are branch parts that merge from the front side in the running direction. When the speed is slow at the next branch portion, the magnet 7 follows the route B3a of the branch portion and shifts to the inner course.

  When the speed is high, the magnet 7 follows the route of the center course that is currently traveling by inertia, without following the route B3a of the branching portion. On the other hand, if the speed is reduced in a state where the magnet 7 is guided on the route of the center course, the vehicle travels on the center course, but the speed is increased in a state where the magnet 7 is guided on the route of the center course. Until now, due to the inertia, the magnet 7 is guided from the branch line B3a to the line B3b, and the magnet 7 follows the outer course. As a result, the course is changed from the center course to the outer course. Done.

  Furthermore, if the speed of the toy car running on the inner course is reduced, the magnet 7 is guided along the first branch line B3b, so that the center course is changed, and thereafter the center course described above is changed. It performs the same operation as a running car toy. And when the speed is high at the first branch part, the magnet 7 is not guided to the route B3b, but goes straight on the inner course.

  As described above, when the speed of the toy car is slow at the branching portion, the magnet 7 follows the running line and the course line in the continuous state, and the speed of the toy car is low. In the case of high speed, the magnet 7 travels following a route away from the traveling route.
