<Operation>
When the power switch 51 (see the schematic diagram of FIG. 4) of the traveling body 50 is turned on, the traveling body 50 travels in a predetermined direction while floating from the floor 11 of the rail 10. In FIG. 1, the power switch 51 is not shown.
Hereinafter, details of the traveling toy 100 will be described.

"details"
<About rail 10>
The base of the rail 10 is not particularly limited, but is made of plastic and transparent. The rail 10 includes side walls 12 on both sides in the width direction of the traveling path of the traveling body 50. The two side walls 12 and 12 are for restricting movement of the traveling body 50 in the width direction.
On the floor 11 of the rail 10, round first permanent magnets 13 are provided at predetermined intervals along the traveling path in the center in the width direction. Although this first permanent magnet 13 is not particularly limited, it is a ferrite magnet. For example, the first permanent magnet 13 is installed in such an orientation that the N pole is on the upper surface side and the S pole is on the lower surface side. The first permanent magnet 13 may not be round. Each of the first permanent magnets 13 may be formed by a set of a plurality of small magnets.
In addition, the floor 11 of the rail 10 is provided with second permanent magnets 14 extending along the traveling path on both sides in the width direction. A rubber magnet is used as the second permanent magnet 14 in consideration of ease of installation. The rubber magnet has a structure in which small magnet portions are arranged side by side in a direction orthogonal to the traveling path. In each small magnet portion, the vertical ends are mutually different magnetic poles. For example, in the small magnet portion, if the upper side is N pole, the lower side is S pole, and if the upper side is S pole, the lower side is N pole. Thus, the rubber magnet has a structure in which N poles and S poles are alternately arranged in a direction orthogonal to the traveling path on the upper surface side and the lower surface side. The second permanent magnet 14 may not be a rubber magnet. Moreover, it may not be a series of magnets. For example, a plurality of magnets may be arranged, as long as a repulsive force can be generated between the traveling body 50 and the third permanent magnet 62 to float the traveling body 50.
Moreover, the connection part 15 with the other rail 10 is provided in the both ends of the running direction of the rail 10. As shown in FIG. Specifically, a dovetail-shaped ant 15a is provided at one end in the traveling direction of the rail 10, and a dovetail-shaped ant groove 15b is provided at the other end. The ant 15a and the ant groove 15b have shapes that fit together. In this way, each rail 10 is provided with a connecting portion 15 so that the rails 10 can be connected one after another. In addition, the structure of the connection part 15 is not limited to the ant 15a and the ant groove 15b.
As the rail 10, a straight rail is shown in FIG. 1, but it may be a curved rail as shown in FIG. 2, or a meandering rail or other curved rail.

<About traveling body 50>
The traveling body 50 includes a body 60 and a chassis 70 (see the bottom view of FIG. 3).
1. Structure of the body 60 The body 60 has a pointed shape. On the left and right sides of the body 60, there are rollers 61 at the front and rear, respectively. The roller 61 comes into contact with the side wall 12 of the rail 10 and rolls as the traveling body 50 travels.

2. Structure of Chassis 70 Third permanent magnets 62 are provided on the left and right sides of the lower surface of the chassis 70 at the front and rear, respectively. A rubber magnet is used as the third permanent magnet 62. As described above, the rubber magnet has a structure in which small magnet portions are aligned and coupled in the width direction of the chassis 70. In each small magnet portion, the vertical ends are mutually different magnetic poles. For example, in the small magnet portion, if the upper side is N pole, the lower side is S pole, and if the upper side is S pole, the lower side is N pole. Thus, the rubber magnet has a structure in which N poles and S poles are alternately arranged in the width direction of the chassis 70 on the upper surface side and the lower surface side. And when setting the traveling body 50 to the rail 10, it sets so that the magnetic pole of the small magnet part which opposes up and down may become the mutually same pole. As a result, the traveling body 50 can be lifted from the floor 11 of the rail 10.
FIG. 4 is a side view schematically showing the traveling body 50. As shown in FIG. 4, a chassis 70 is provided with a lithium battery 71, a reed switch 72, and a coil 73 that constitutes an electromagnet. FIG. 5 shows an excitation circuit for the coil 73. As shown in FIG. 5, in this excitation circuit, the reed switch 72, the coil 73, and the power switch 51 are connected in series to the lithium battery 71. In the running toy 100 according to the embodiment, the reed switch 72 is repeatedly turned on and off, so that deterioration of durability due to the occurrence of a spark or the like becomes a problem. To avoid this problem, a driver including a transistor circuit is used. The circuit can also be incorporated in the excitation circuit. Further, instead of the lithium battery 71, a dry battery may be mounted.
Further, as shown in FIG. 3, wheels 74 are installed on the left and right sides of the chassis 70 at the center in the front-rear direction. The wheel 74 does not contact the floor 11 of the rail 10 while the traveling body 50 is traveling normally. The wheels 74 are grounded and rolled on the floor 11 of the rail 10 when the traveling body 50 rolls when traveling along a curve or the like.
In the present embodiment, two traveling bodies (connectors) 50 having such a structure are connected. However, in each traveling body 50, when connected, the reed switch 72 and the coil 73 are installed so that the reed switch 72 is positioned on the front side in the traveling direction and the coil 73 is positioned on the rear side in the traveling direction. Yes. When two traveling bodies 50 are connected, the lithium battery 71 and the power switch 51 may be shared.

<Operation>
Next, the positional relationship between the reed switch 72 and the coil 73 will be described together with the operation of the traveling toy 100. In this traveling toy 100, it can play as one traveling body 50, or it can play even if two traveling bodies 50 are connected.
(In the case of one traveling body 50)
First, the case of one traveling body 50 will be described.

1. Mechanism of Levitation The third permanent magnet 62 under the chassis 70 of the traveling body 50 faces the second permanent magnet 14 of the rail 10. Since the opposing portions of the third permanent magnet 62 and the second permanent magnet 14 have the same magnetic pole, a repulsive force is generated and the traveling body 50 floats.

2. The stationary position of the traveling body 50 The traveling body 50 stops on the rail 10 when the power switch 51 is turned off. At this time, as shown in FIGS. 6 and 7A, the traveling body 50 is stationary at a position where the third permanent magnet 62 at the left and right front part and the third permanent magnet 62 at the left and right rear part sandwich the one first permanent magnet 13. To do. This is because, at this position, the magnetic force acting on the third permanent magnet 62 at the left and right front parts balances the magnetic force acting on the third permanent magnet 62 at the left and right rear parts.
In this stationary position, the reed switch 72 is located at an intermediate position between the adjacent first permanent magnets 13, and the reed switch 72 is located in a non-operating area outside the operating area A. In this stationary position, the coil 73 is located behind the first permanent magnet 13 on the rear side among the first permanent magnets 13 sandwiching the reed switch 72.
At this stationary position, the reed switch 72 is in a non-operating range, so even if the power switch 51 is turned on, the reed switch 72 does not operate and the coil 73 is not excited.

3. Traveling of the traveling body 50 When the traveling body 50 is slightly moved to the left from the position of FIG. 7A, the reed switch 72 enters the operating area A caused by the first permanent magnet 13 on the front side as shown in FIG. 72 is activated. At this time, the coil 73 is slightly ahead of the rear first permanent magnet 13. Therefore, when the reed switch 72 is operated, the coil 73 is excited and the lower side becomes the N pole, and the upper side of the first permanent magnet 13 is the N pole. Therefore, a repulsive force is generated between the coil 73 and the first permanent magnet 13. As a result, the traveling body 50 travels forward.

  When the traveling body 50 further travels and the reed switch 72 exceeds the first permanent magnet 13 and deviates from the operating area A caused by the first permanent magnet 13 as shown in FIG. 7C, the reed switch 72 is in an inoperative state. It becomes. When the reed switch 72 is deactivated, the coil 73 is demagnetized. As a result, the coil 73 does not receive a repulsive force (propulsive force) from the first permanent magnet 13, but the traveling body 50 is propelled by the inertial force, and the traveling body 50 travels forward, again in the state of FIG. 7B. To. Thereby, the traveling body 50 continues traveling.

(In the case of two traveling bodies 50)
Next, the case of the connected traveling body 50 will be described.
1. Ascent mechanism The ascent mechanism is the same as that of a single unit. Therefore, the description is omitted.

2. The stationary position of the traveling body 50 The traveling body 50 stops on the rail 10 when the power switch 51 is turned off. At this time, the traveling body 50 takes either the first stationary position or the second stationary position.
As shown in FIG. 8A, the first stationary position includes the left and right rear third permanent magnets 62 of the front first traveling body 50a and the left and right front third permanent magnets of the rear second traveling body 50b. 62 is a position between the adjacent first permanent magnets 13. Further, as shown in FIG. 8B, the second stationary positions are the third permanent magnets 62 at the left and right rear portions of the first traveling body 50a on the front side and the third left and right front portions of the second traveling body 50b at the rear side. This is a position where the permanent magnet 62 sandwiches one first permanent magnet 13. This is because magnetically stable at these positions.

  In the first stationary position, the reed switch 72 of the first traveling body 50a is positioned in the non-operating area outside the operating area A, and the reed switch 72 of the second traveling body 50b is positioned in the operating area A. Further, in the second stationary position, the reed switch 72 of the first traveling body 50a is positioned in the operating area A, and the reed switch 72 of the second traveling body 50b is positioned in the non-operating area outside the operating area A. Yes.

3. When the traveling body 50 is in the first stationary position, when the power switch 51 is turned on, the reed switch 72 of the second traveling body 50b is operated, and the coil 73 is repelled by the first permanent magnet 13. Upon receiving (propulsive force), the traveling body 50 travels forward. At this time, the reed switch 72 of the first traveling body 50a is not operated because it is in the non-operating range. When the traveling body 50 travels forward, this time, the reed switch 72 of the first traveling body 50a reaches the operating area A, and the reed switch 72 of the second traveling body 50b reaches the non-operating area. As a result, the reed switch 72 of the first traveling body 50a is activated, the coil 73 receives a repulsive force (propulsive force) from the first permanent magnet 13, and the traveling body 50 travels forward. At this time, the reed switch 72 of the second traveling body 50b is inactive.
As described above, the reed switch 72 of the first traveling body 50a and the reed switch 72 of the second traveling body 50b are alternately operated, so that the traveling body 50 continues traveling.
When the traveling body 50 is in the second stationary position, when the power switch 51 is turned on, the reed switch 72 of the first traveling body 50a is actuated, and the coil 73 is repelled by the first permanent magnet 13 (propulsive force). ), The traveling body 50 travels forward. At this time, the reed switch 72 of the second traveling body 50b is not operated because it is in the non-operating range. When the traveling body 50 travels forward, the reed switch 72 of the second traveling body 50b reaches the operating area A, and the reed switch 72 of the first traveling body 50a reaches the non-operating area. As a result, the reed switch 72 of the second traveling body 50b is activated, the coil 73 receives a repulsive force (propulsive force) from the first permanent magnet 13, and the traveling body 50 travels forward. At this time, the reed switch 72 of the first traveling body 50a is inactive.
As described above, the reed switch 72 of the first traveling body 50a and the reed switch 72 of the second traveling body 50b are alternately operated, so that the traveling body 50 continues traveling.
As described above, if the reed switch 72 of the first traveling body 50a and the reed switch 72 of the second traveling body 50b are operated alternately, the traveling time is shortened by the inertial force, so that the speed is increased. Can be raised.

<conditions>
Next, it is necessary to satisfy the following conditions (1 and 2) regarding the relationship between the interval and size of the reed switch 72 and the coil 73 and the interval and size of the first permanent magnet 13.
1. When the reed switch 72 enters the operating range A, that is, when the reed switch 72 is turned on, the coil 73 is in a position to receive a repulsive force in the propulsion direction.
Specifically, when the reed switch 72 enters the operating range A, the coil 73 may be in a position to receive a repulsive force from the one first permanent magnet 13 in front of the one first permanent magnet 13 in the propulsion direction. is necessary.
If the coil 73 is in a position that receives a repulsive force from the one first permanent magnet 13 on the rear side in the propulsion direction with respect to the one first permanent magnet 13, the repulsive force is received in a direction opposite to the propulsive direction. Then, the brake is applied to the traveling body 50, and the traveling body 50 is stopped or decelerated.
Moreover, if it exists in the position which does not receive a repulsive force from the said 1st 1st permanent magnet 13 in the propulsion direction front rather than the said 1st 1st permanent magnet 13, the traveling body 50 will be traveled using a repulsive force. It will not be possible.

2. When the reed switch 72 comes out of the operating range A, that is, when the reed switch 72 is turned off, the coil 73 is more than the middle of the first permanent magnet 13 and the next first permanent magnet 13. 1 Located on the permanent magnet 13 side.
When the reed switch 72 leaves the operating area A, the coil 73 is positioned closer to the next first permanent magnet 13 than the middle between the first first permanent magnet 13 and the next first permanent magnet 13. Then, the coil 73 receives a repulsive force from the next first permanent magnet 13 in the direction opposite to the propulsion direction, the brake is applied to the traveling body 50, and the traveling body 50 is stopped or decelerated. Become.

The interval and size of the reed switch 72 and the coil 73 and the interval and size of the first permanent magnet 13 are set so as to satisfy the above conditions.
If the conditions are satisfied, the positions of the reed switch 72 and the coil 73 can be reversed. That is, in the present embodiment, the reed switch 72 is provided on the front side in the propulsion direction and the coil 73 is provided on the rear side in the propulsion direction. However, the coil 73 is provided on the front side in the propulsion direction. May be provided.
<effect>
According to the traveling toy 100 configured as described above, the following effects can be obtained.

1stly, according to this traveling toy 100, since the reed switch 72 and the coil 73 are provided in the traveling body 50 side, compared with the case where the reed switch 72 and the coil 73 are provided in the rail 10 side, it is simple. It can be set as a simple structure. That is, when a set of the reed switch 72 and the coil 73 is provided on the rail 10 side, it is necessary to provide a number of sets of the reed switch 72 and the coil 73, but the reed switch 72 and the coil 73 are provided on the traveling body 50 side. If the group is provided, the number is small.
Secondly, according to this traveling toy 100, since the first permanent magnets 13 are only arranged at equal intervals, if the direction of the traveling body 50 is reversed, the traveling body 50 can be easily traveled in the opposite direction. be able to.
Thirdly, according to the traveling toy 100, the traveling body 50 can be caused to travel with the repulsive force between the second permanent magnet 14 and the third permanent magnet 62. Therefore, there is no sliding contact between the traveling body 50 and the floor 11 of the rail 10, and the traveling body 50 can travel smoothly.

Fourthly, according to the traveling toy 100, since the movement of the traveling body 50 in the width direction is restricted by the side wall 12 of the rail 10, the traveling body 50 can be stably traveled by magnetic force. The wall 12 may not be located on both sides in the width direction of the rail 10 as long as the movement in the width direction can be restricted.
Fifthly, according to the traveling toy 100, the magnetic force acting between the first permanent magnet 13 and the coil 73 is a repulsive force, so that the traveling body can be smoothly traveled. If suction force is used instead of repulsive force, it depends on the cutoff timing of the suction force. However, if the cutoff timing is delayed, the suction force becomes a brake. Less is.
Sixth, according to this traveling toy 100, since the traveling body 50 is provided with a roller that rolls against the side wall 12, the traveling body 50 does not slidably contact the wall 12, and smoothly. The traveling body 50 can travel.
Seventh, according to the traveling toy 100, the traveling body 50 comes into contact with the floor 11 of the rail 10 because the wheel 74 is grounded to the floor 11 when the traveling body 50 rolls during curved traveling or the like. And the traveling body 50 can be smoothly traveled.

  As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment, In the range which does not change the summary of the invention, it can change variously.

  For example, in the above-described embodiment, a case where two traveling bodies 50 are traveled by connecting two traveling bodies 50 and alternately turning on the reed switches 72 of the two traveling bodies 50 will be described. However, two sets of the reed switch 72 and the coil 73 may be provided on one traveling body 50, and the two reed switches 72 may be alternately turned on.

  Moreover, in the said embodiment, the case where two traveling bodies 50 are made to travel by connecting the two traveling bodies 50 and alternately turning on the reed switches 72 of the two traveling bodies 50 is described. However, the operation timings of the reed switches 72 of both traveling bodies 50 may be synchronized. Also in this case, two sets of the reed switch 72 and the coil 73 may be provided in one traveling body 50.

  Moreover, although the example which connected the two traveling bodies 50 was shown in the said embodiment, you may connect the three or more traveling bodies 50, In this case, the action | operation of the reed switch 72 of these traveling bodies 50 The timing may be shifted from each other to shorten the time for traveling with inertial force, or the operation timing of the reed switch 72 may be synchronized. Or you may combine the thing from which an operation timing differs, and the thing from which an operation timing synchronizes. Even in this case, three or more sets of the reed switch 72 and the coil 73 may be provided in one traveling body 50.

  Furthermore, in the said embodiment, although the reed switch 72 was provided as a magnetic force detection part, you may provide a Hall sensor. The point is that the magnetic force of the first permanent magnet 13 can be detected. Note that a mark or the like may be detected mechanically or optically without detecting the magnetic force of the first permanent magnet 13.

  In addition, an electromagnet may be provided instead of the third permanent magnet 62, but the circuit becomes more complicated and the power consumption increases.

  The present invention can be suitably used in the field of traveling toy manufacturing.
