Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a traveling toy using a linear motor.

[Background of the invention]

Conventional running toys are equipped with a DC motor that drives the wheels through transmission means such as gears, and use the frictional resistance with the running road to propel the vehicle forward or climb hills, while others are linear motor cars. There was one that applied the principle of The wheels of the former type of toy would sometimes spin, so there was a limit to how fast it could be run, and there was also the problem of the toy sliding down when the slope of the sloping road became steep. Although the latter type of running toy has better high-speed running performance, it has the problem of jumping out of the running road around curves, etc., and being unable to run on loop-shaped or vertical running tracks.

[Purpose of the invention]

In view of the above points, it is an object of the present invention to provide a running toy that can run on curves at high speed and does not fall even on vertical or loop-shaped tracks. .

[Structure of the invention]

In order to achieve the above object, the present invention provides permanent magnets that are alternately and continuously arranged with their magnetic poles reversed, and contact pieces of different polarities are alternately and continuously arranged along the arrangement direction of the permanent magnets. A state in which the traveling body is attracted to the traveling road, and the traveling body is equipped with a plurality of electromagnets that can be contacted with the contact pieces of the traveling road via a current collector, and is equipped with wheels made of magnetic material. It is constructed so that it can be run at

〔Example〕

Next, the present invention will be described based on embodiments shown in the accompanying drawings.

In the figure, reference numeral 1 denotes a running path, and the running path 1 is made of a base body 20 made of an insulating material such as plastic, and a permanent magnet 3 is arranged along the length direction at the widthwise center of the base body 20, with its magnetic poles (N and S) reversed. A substrate 5 is placed on the top surface of the permanent magnet 3 on which the contact pieces 4, 4' are printed, the contact pieces 4, 4' being alternately arranged in series, and the cover integrated 6 is placed on the upper surface of the permanent magnet 3.
covered. This cover unit 6 has two rails 7.7' at the center of the upper surface in the width direction, and the rails 7.7'.
A through hole 8 is provided in the entire area between 7' so that the contact pieces 4, 4' on the upper surface of the printed circuit board 5 are exposed. This cover unit 6 can be fixed by locking a hook member 9 provided on the side surface to an inner edge step 11 of a hole 10 made in the lower plate 2' of the base body 2.

This traveling path 1 is prepared in many shapes such as straight lines, curved lines, etc., and one end surface of each path is provided with a plug 12.12.
', but plug holes 13° and 13' are provided on the other end surface, and the structure is such that they can be connected endlessly by connecting them. The plug 12.degree. 12' is connected to the contact piece 4.degree. 4' via contact pieces 12a, 12b. Also, plug hole 1
The plug 12.12' connected to 3.13' is the contact piece 13a.

It is connected to the mating contact piece 4.4' via 13b.

Therefore, due to the above connection, the contact pieces 4 and the contact pieces 4' between the travel paths 1.1 are electrically connected to each other.

Reference numeral 15 denotes a running body, and the running body 15 has three electromagnets 17, 18, and 19 mounted in a body 16, and is provided on the upper surface of the cover integral 6 of the running path 1 at the front and rear of the podium 16. It is equipped with wheels 20.21 which ride on rails 7.7'. The wheels 20, 21 are made of a magnetic material so that the attraction force of the permanent magnet 3 acts.

The electromagnets 17, 18, and 19 have their bases inserted into the center holes of the iron core a, and their tips protrude from the lower surface of the traveling body 15 so as to be connected to the traveling path 1.
The upper contact piece 4.4' is provided with collectors 22, 23, 24 that can be lightly (slidingly) contacted by a spring 25. These collectors 22-2
4, two of them are always the positive terminal of the power supply 26.
The current flows alternately in the direction of arrow A or B through the coil b wound around the iron core a of each electromagnet 17°18. A moving magnetic field is formed between the permanent magnets 3 having N and S poles arranged alternately, and the traveling body 15 is caused to travel in the direction of the arrow. In this case, the wheels 20.21 of the traveling body 15 are used to cause the traveling body 15 to run along the rail 7.7' and to exert the attractive force of the permanent magnet 11, but do not play a role in transmitting the traveling force. Not yet. Therefore, it may be replaced with something like a sled or a sphere that can be fitted between the rails.

Note that 27 is the exterior of the traveling body 15, which is usually used for automobiles,
It is in the form of a train, etc.

In the above embodiment, when the wheels 20.21 of the traveling body 15 are placed on the rails 7.7' provided on the upper surface of the cover 6 of the traveling path 10 and the switch (not shown) is turned on, the traveling body 15
Contact piece 4 that protrudes from the bottom surface of and is the positive pole above the running path 1.
Then, a current flows in a predetermined direction to the coil b wound around the iron core a of each electromagnet 17, 18, 19 through the two current collectors that are in sliding contact with the contact piece 4', which is the negative pole, and the running path 1 A moving magnetic field is formed between the moving body 15 and the permanent magnets 3 disposed at , causing the traveling body 15 to travel in the direction of the arrow. This traveling speed can be adjusted using, for example, a variable resistor (not shown).

Also, while traveling, the wheels 20 of the traveling body 15 made of magnetic material are
．． 21 sticks to the running track 1 due to the magnetic force of the permanent magnet 3, so even if the running speed is high, the running body will not derail at a curve, and even on a loop-shaped running track, it will not move vertically. It is possible to run freely on both a running path along a wall or a running path along a ceiling.

Note that the traveling body 15 can be made to travel in the opposite direction by changing the positive and negative directions of the power source 26.

〔Effect of the invention〕

As explained above, the present invention provides a running path in which permanent magnets are alternately and consecutively arranged with their magnetic poles reversed, and contact pieces of different polarities are alternately and consecutively arranged along the arrangement direction of the permanent magnets. , is characterized by being equipped with a plurality of electromagnets that can be contacted with the contact piece of the running path via a current collector, and also consisting of a running body equipped with wheels made of magnetic material, so it provides a sense of stability during high-speed running. This not only eliminates the possibility of derailment when traveling on curves or curves, but also allows for free travel on vertical paths, loop paths, etc., and provides various excellent effects.
