Abstract

A toy car race track having easy and difficult track sections is provided with voltage in such a way that the vehicle can always run out of the difficult track section when the mains voltage is switched off and subsequently comes to a standstill on an easy track section. Restarting when the mains voltage is switched on is therefore reliably guaranteed.

Description

RACING TRACK LOCATION

The invention relates to a car racing track system.

Car racing tracks have track pieces with guide means and associated Vehicles. The guide means are bands or grooves in the side that lead along Fabrication area. Current conductors run parallel to the guide means from which the vehicles draw energy. Electricity with different voltages is supplied. The regulation of this voltage is mostly done with hand controls.

In the present case, at least one lane of the car racing track system is used powered in such a way that the vehicle on it runs automatically. In the second lane, a playing child can then operate his vehicle manually.

For certain purposes, in particular shop window systems, an automatic operation for two or more lanes can also be provided.

Automatic operation is then easy to achieve, if the route runs relatively evenly This means that there are no tight bends or there are other difficult sections of the route.

In these cases a simple regulating transformer can be used, which supplies a constant voltage. The vehicle then drives with average or slower speed on this simple system.

An increasing game stimulus for a teammate or an increasing one However, the attraction of showpieces is achieved when there are difficult sections of the route to be added. Such route sections are, for example, banked curves or a Looping. In the case of vehicles with magnetic adhesion, route sections can also be used be built that run along a vertical wall or route sections, in which the vehicle drives hanging along the route that is in front of the ceiling is located, provided that the magnetic adhesion is great enough.

These difficult sections of the route have to be driven at an appropriate speed be driven through. A loop must be driven through quickly because the vehicle Otherwise, if it does not have magnetic adhesion, it will fall down at the top point. Steep turns must also be driven through at higher speed. The attraction of gaming is now alternating between slow and fast driving style, which is caused by acceleration and braking is achieved. In the case of automatic operation, corresponding Precautions are taken.

Even if it varies accordingly in automatic operation If voltage is provided, additional difficulties arise when the shutdown is arbitrary. This is the case, for example, when the plant with the shop window lighting is switched on and off automatically. It can so the case occur that the vehicle, which in this case no magnetic adhesion has, stops in the loop and falls down due to lack of power and speed. A Vehicle in a banked curve can slide down when the voltage is interrupted. The vehicles then no longer start up automatically, so that automatic operation not possible.

The present invention creates a possibility, despite being built-in Difficulties in ensuring automatic operation in the course of the route according to the characterizing part of the main claim.

It is achieved in such a way that, on the one hand, the operation takes place as if a pilot operates the regulator and, on the other hand, the switch-off at any time can be done.

For an only child, there is also a great incentive to play, as a vehicle can be operated automatically and the child alone in competition with the automatic driving vehicle operates the vehicle it controls.

The figures show some exemplary embodiments: Figure 1 shows one System with tighter curves and looping, with different points in different places Connections with different voltage values are available.

Fig. 2 shows a system in which a voltage control depending on the route section, on which the vehicle is located, takes place automatically.

Fig. 3 shows a system with automatic operation and any Switch-off option.

In Fig. 1 the racetrack system 1 with the connection points 5 - 14 equipped. These connection points are supplied with current with different voltages provided. The current conductors 16 of the curve pieces 17 receive more driving voltage that Straight line 18 before the curve less, the straight line 18 before the loop 40 maximum tension, the looping track section 19 up to its apex 20 also maximum tension, very little tension from the apex down, etc. This means a trajectory with a Large number of feed-in points and a large number of different track voltages 5 - 14.

According to Fig. 2 there is only one feed point per vehicle. The driving tension is increased or decreased depending on where the vehicle is. In addition but must be at every point on the track, from which the vehicle has its speed should change, sensors 22a to 32a are attached, which in turn regulate the voltage 33 taxes. When operating with two vehicles, double the number of sensors 22b to 32b are required, since the vehicles have the individual at different times Pass train stations.

Of course, a second voltage regulator 34 is also necessary.

Both solutions require an exact setting of the individual voltage values very important. It can vary from vehicle example to vehicle example be.

According to Fig. 3, there is another solution with great operational reliability shown. Vehicles with a higher reduction gear can also be used will. A higher torque is thus available on the drive axle. this has the advantage that the different friction conditions along the Road no longer have such a strong impact on the vehicle's speed. Thus, apart from the looping area 40, a single driving voltage Us is sufficient. Only the looping track section 21 from the entrance to the upper apex 20 is fed with a higher voltage UL. This is due to the strong motor reduction The torque on the drive axle is so great that the vehicle enters the loop strongly accelerated and it goes through the entire looping 40 effortlessly.

The descending part of the loop, looping track section 19, is normal Driving voltage Us fed. This means that the vehicle is already on the descent, due to the high motor reduction, braked so far that it is not with excessive Speed into the flat stretch and into the subsequent curve.

The two driving voltages U5 and UL for the route and the looping 40 are stabilized. This means that mains voltage fluctuations have no effect. aside from that the influence of drive motor tolerances is lower. Stabilizing the looping -voltage UL has another important reason: the mains voltage the system is switched off (e.g. during the night), the vehicles must not fall out, if the mains voltage is switched off at the moment of entering looping 40. The driving voltage must be applied until the vehicles safely through the loop 40 have driven.

With a capacitor of sufficient capacity parallel to the loop voltage would be able to realize this. If the vehicle drives with a voltage of e.g. 25V safely through the loop, it can be critical at 20V. The capacitor voltage may therefore only drop by approx. 10 96 during the looping passage. This requires a very large capacity. The better solution is to have the capacitance parallel to the high voltage, so to switch to the input voltage of the loop voltage regulator 41. At a High voltage of e.g. 40V, the capacitor 52 is allowed to discharge by almost 50% if the minimum voltage difference between the input and output voltage of the voltage regulator is not more than approx. 1V.

A mains transformer, for example, is used here to generate the US and UL traction voltages 42 with two secondary windings 43 and 44 are used. The voltage at 43 is rectified, sieved with the capacitor 45 and stabilized with the voltage regulator 46.

The resistor 47 limits the current so far that in the event of a short circuit there is no inadmissibly high load on the components on the track. To the vehicles and at the moment of start-up when switching on the system with sufficient voltage supply is the resistor 47 and the voltage regulator 46 with the capacitor 48 bridged.

If a vehicle drives through the upper vertex 20 of the loop 40 at high speed, it supplies electricity to the descending looping track section 19, because the vehicle is acting as a generator at that moment. It would be in the exit of the voltage regulator 46 feed current and lead to overloading of the regulator. For this reason, the diode 49 is built into the output line of the traction voltage Us.

Both secondary voltages are used to obtain the looping driving voltage UL connected in series after rectification 50 and 51.

The function of the capacitor 52 has already been described. After this Looping voltage regulator 41 is the stabilized driving voltage UL to disposal. The internal resistance of the power supply must be sufficiently small so that a vehicle standing in front of the loop is safe when the system is switched on again drives through the loop.

The driving voltages US and UL still vary a bit. To avoid stress peaks that are generated on the web, To keep away from the voltage regulators, capacitors 54 and 55 are necessary. the Capacitors 56 to 59 prevent impermissible oscillation of the loop voltage regulator 41 and the voltage regulator 46.
