Description
- The present application claims the benefit of priority of U.S. Provisional Patent Application No. 60/586,122, filed Jul. 7, 2004 for Edward Lopatinsky at al. the entire content of which is incorporated herein by reference.
- The present invention relates generally to electromagnetic moving systems. More particularly, the present invention relates to toy moving devices like cars on railways, amphibian vehicles and/or submarines.
- There are numerous designs of electromagnetic moving systems like miniature toy railway systems that include a track and at least one vehicle located on said track.
- There are known systems of this type, for example, U.S. Pat. No. 4,861,306 “Toy Cog Railway” and U.S. Pat. No. 6,648,724 “Toy Railway Liquid Transfer Facility”, that include the track (platform, chassis) driven by an engine and vehicle mounted on said track.
- Another type of these systems, for example, U.S. Pat. No. 3,729,866 “Toy Railway Vehicle and Switching Section”, comprises battery powered vehicle with electric motor.
- The most widespread of known electromagnetic moving systems using as miniature toy railway systems include the track comprising at least one conductive band that is part of an electrical supply line which gives a power to the electric motor of said vehicle,—see, for example, U.S. Pat. No. 4,217,727 “Miniature Monorail System”.
- The main problem of all known systems is that it is very difficult to provide reliable speedy moving vehicle because of the lack of stable attraction between a vehicle and a track, especially at the higher speed on the turns, also with vertical or almost vertical sections as a vertical ring or spiral. Even when track sections are located horizontally the vehicle moving with high speed can lose stability and get of the track. So, known electromagnetic moving systems must include special means providing reliable attraction between a vehicle and a track. In some cases it was done by using magnets on the bottom of the vehicle and making track from magnetic conductive (attractive) material. But these means in known systems also make additional resistance to the moving vehicle and needs much more power to move it. Most of such toys are having some special brushes that provide electrical contact with the electric grid. Or they might be batteries operating that not require any brushes, but instead need the control trough the wire or wireless and have limited operating time due to the batteries life.
- Therefore, it would be generally desirable to provide an electromagnetic moving system that overcomes these problems and has reliable attraction between the vehicle and the track and at the same time to function as a moving device for such vehicle. Also, it is desirable to make this system as brushless connected directly to the power supply with no wireless control.
- According to the present invention an electromagnetic moving toy systems comprises a track and at least one vehicle located on said track. The general idea of the claimed invention is that the track and the vehicle of the system should be made as two parts of common electromagnetic drive which provides moving abilities of the vehicle along the track with good stable attraction between the vehicle and the track.
- In order to achieve these objectives, according to the first embodiment of the present invention, the track comprises electrically connected coils windings, powered by electrical grid and controlled by switching controller in such way that at least two adjacent coil windings operating in time. The coils windings serve as a stator and located in a series way along the track. The vehicle comprises magnetic means interacting with the coils windings so the magnetic means serve as a moving body providing a possibility for moving of the vehicle.
- The magnetic means are made as permanent magnets located along the vehicle with alternative polarity. The stator may further comprise a core made of magnet-conducting material with high eddy current resistance, made for example from silicon steel.
- The electromagnetic interaction between the coils windings of the track and the magnetic means of the vehicle not only moves the vehicle, but it also provides at the same time, reliable attraction between the vehicle and the track in any possible configuration and location without any special additional means for it. It makes the electromagnetic moving toy system much more stable, reliable and gives the opportunity to operate at higher speed of the vehicle and in any position of it, thus providing the possibility to make the track as vertical ring or spiral, or in any other configuration. It also simplifies the system and makes it more durable because it is not necessary to use any kind of brushes.
- According to the second embodiment, the electrically connected coils windings placed on the bottom part of the vehicle and connected directly to a power source located on the vehicle. Magnetic means located in a series way along the track and interact with the coils windings located on the vehicle, thus represent another way to achieve the similar goal by using the same general idea. Magnetic means are made as permanent magnets located along the track with alternative polarity. It gives, in general, similar effect as mentioned first embodiment. Such configuration provides the minimum necessary power usage and, as a result, the essential economy of energy.
- The coils windings serve as a stator. The stator may comprise a core made of magnet-conducting material with high eddy current resistance, made for example from silicon steel. In this case the efficiency of electromagnetic interaction between the coils windings of the vehicle and the magnetic means of the track is much higher that provides economy of energy.
- According to the third embodiment, the electromagnetic moving toy system is made as the miniature amphibian toy vehicle that can move like a ship on water surface also.
- And, according to the forth embodiment, the electromagnetic moving toy system is made as miniature toy submarine that can flow in water also along the sealed track in any directions including up and down.
- The coils windings may make as Printed Circuit Board coils.
- The foregoing and other objectives, features and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

As a result thevehicle 3 moves along thetrack 2. When saidvehicle 3 approaches to the next part of thetrack 2 with twoadjacent coils windings vehicle 3 continues to move and so on. - According to the second embodiment (
FIG. 2 ), which is another way to achieve the same goal of the present invention, the electrically connectedcoils windings 4 placed on the bottom part of thevehicle 3 and connected directly to anautonomous power source 11 located on thevehicle 3.Magnetic means 7 located in a series way along thetrack 2 and interact with thecoils windings 4 located on thevehicle 3, thus represent another way to achieve the similar goal by using the same general idea.Magnetic means 7 are made aspermanent magnets 9 located along thetrack 2 with alternative polarity. It gives, in general, similar effect as mentioned first embodiment. Such configuration provides the minimum necessary power usage and, as a result, the essential economy of energy. - The electromagnetic moving
toy system 1 according to the second embodiment operates in the following ways. The electrical power is supplied from autonomous power source (battery) 11 to the electrically connectedcoils windings 4 placed on the bottom part of thevehicle 3 creating an alternating electromagnetic field. This electromagnetic field interacts with a magnetic field created by themagnetic means 7 of thetrack 2. As a result thevehicle 3 moves along thetrack 2 similar to the first embodiment. - There are some design options of electromagnetic moving
toy system 1 according to the third (FIG. 4 ) and fourth (FIG. 5 ) embodiments. Thus, the electromagnetic movingtoy system 1 is made as the miniature amphibian toy vehicle 3 (FIG. 4 ) that can move like a ship on water surface. And, the electromagnetic movingtoy system 1 can be made as the miniature toy submarine vehicle 3 (FIG. 5 ) that can move in any directions including up and down and flow under water also.
