Electric power is supplied to the rail assemblies 12 and Ik from any suitable power source, such as dry battery 52, which has a negative terminal 5k and a positive terminal 56 . The negative terminal 5k is connected by a line 58 to the central electrical bus bars 36 and 38. The positive terminal 56 is by a line 60 to the coil 68 of a first slide resistor 62 and by a line 6k to the coil 118 of a second Sehiebe resistance 66 connected. The coil of the resistor 6Z leads to an electrical contact 218, which can be touched by a leaf spring 21 6 in a manner described below in order to close a circuit via a contact 70 a to a line 70 and thereby the full resistance of the coil 68 to the contact tongue 72 of a 3-position switch 7 ^ zn. The leaf spring 216 can also touch a contact 222, which is connected to the sliding contact 61 of the resistor 62.

leads. Finally, the switch 7k also has a left-hand contact 8k, which is connected by a line 86 to the outer busbars Zk of the left-hand curve section 18 of the mentioned rail arrangements. As a result, the switch Jk can be used to close a circuit zu.den outer busbars Zk of the straight section 16, the left curve section 18 or the right curve section 20 of the rail assemblies 12 and Ik , depending of which of the contacts 80, 8k or 76 touches the contact tongue 72.The contact tongue 72 is firmly connected by a control shaft 89 to a control wheel 88, so that in a central position of the control wheel 88 the contact tongue 72 touches the contact 80 and thus a circuit to the straight section 16 of the rail assemblies 12 and 14 closes * Furthermore, the steering wheel 88 can be rotated to the right, as shown in Figure 1, until the contact tongue touches the contact 76 and thereby creates a circuit to the right-hand curve - Section 20 of the aforementioned rail arrangements closes. In addition, said steering wheel can be turned to the left until the contact tongue 72 touches the contact 8k , whereby a circuit to the left curve section 18 of the rail assemblies 12 and "\ k" is closed.

The busbars 36 and Zk of the rail arrangement 12 and the busbars 38 and Zk of the rail arrangement 14 lead, as soon as energy is supplied to them, electrical current to an electric racing car kZ via an electrical sliding contact 92 on the underside des, the ¥ agen front axle

Busbars 22 of the right Kuryen section 20, the straight section 1.6 and the left curve section 18 are connected. The coil 118 of the mentioned resistor 66 is connected to a contact 218 a, with which a leaf spring 216 a can come into contact * - to close a circuit via the line 120 to the contact tongue 122 of the mentioned switch 104 »The leaf spring 216 a can also come into contact with a contact 222 a, which has a connection to the sliding contact 65 of the aforementioned sliding resistor 66. In this way, too, a circuit to the contact tongue 122 of the switch 104 can be closed ^{124 connected to} contacts 106, 108 or 110 via control shaft 125

The carriages can change over from the rail arrangement Ik to the rail arrangement 12 by means of a switch circuit 172, whereby through the supply lines 22a, 38a and kZa. the busbars 22, 38 and Zk of the rail arrangement 14 are conductively connected to the busbars 22, 36 or * Zk of the rail arrangement 12 ·,.

The sliding resistors 62 and 66 as well as the control wheels 88 and λZk can be accommodated together with the rotary switches 7k and 104 in a suitable device, e.g. in the control unit 126 shown in FIG. 2-8, as is the case here for the resistor 62 and switch 7k is shown.

The control unit 126 consists of a housing 128 with a cover 130, a side wall 132 and a bottom wall 134. The control shaft 89 is rotatable in the bottom wall 134 stored and the contact tongue 72 sits firmly on the control shaft 89 and protrudes beyond contacts 76, 80 and 84, which in turn firmly in a recess 134 a of the bottom wall 134 are arranged (Figure 5) · Di © coil 68 of the sliding resistor 62 is firmly housed in the housing 128 and can, as shown in the diagram is shown in Figure 1, are conductively connected to the contact tongue 72 by a leaf spring 216 via the supply line 70. The sliding contact 61 of the sliding resistor 62 sits on one Extension I38, which extends through a long slot 14O in the deck wall 130 of the housing 128 extends vertically upward. A saddle-like indentation worked out for the fingertip 142 sits at the upper end of the extension I38 and has a Suitable pointer. 144 on which in turn with Kenn-Harken 146 on the deck wall I30 is aligned to the user the control unit 126 the relative position of the sliding contact 61 to display on the spool 68, so that this gives an indication of the speed of the racing car 42, normally a circuit through which contact 222, closed by the leaf spring 21 β, runs

The collective contacts $ 2 and 100 of the racing car 42 carry the energy via lines 164 and I66, respectively, to an electric motor, not shown here. The yoke 96 can be pivoted by means of a suitable pin, which is not shown, on the said car

The racing car 42 can be monitored on the rail assembly 12 or lh by the control unit 126 by operating the sliding contact 61 and the steering wheel 88 accordingly. It will be apparent to one of ordinary skill in the art that the top speed of the racing car can be achieved by moving the sliding contact 61 to a position on the spool 68 in which the lowest possible ¥ Resistance size in the circuit from the battery 52 to the busbars Zh results. Once the called racing car hZ passes as it travels in the direction of arrow 176, as shown in FIG 1, the left-curve 18, the operator has to this racing car the wheel rotate 88 to the left, so that the contact plate 72 touches the contact 8h to to close a circuit to the left curve 18 and the power rail Zh behind the current interruption point caused by the pin hS receives energy. The operator of the racing car hZ can simultaneously monitor the car speed by actuating the sliding contact 61 in the control unit 126, so that the named racing car runs through the curve 18 at the optimum speed.

The race carried out by Hagen hZ appears to be authentic by imitating the conditions prevailing in a real race. This is achieved in part by the fact that a steering control means is provided, the mode of operation of which is detailed in the above-mentioned previous patent application by the same applicant has been described

and on the other hand by the fact that the means of a racetrack box imitation is created according to the present application.

The simulated racetrack box, generally designated 150, can lie next to the rail arrangements 12 and 14, as is shown schematically in FIG. 1. This box 150 has a housing assembly 152; with a bottom wall 154, end walls 156, a front wall 158, a rear wall 160 and a top wall 162 · The top wall 162 has four suitable, spaced apart, longitudinal slots or openings 164, which the wheels of the car 98 may receive 42, when the carriage needs to be serviced (see figures 2 and 3) · the cover wall 102 also still has a longitudinal slot 166 which the, 42, provided on the yoke 96 of the carriage slide guide

, generally designated I78, which contains the, in a real race track box, there is an electronic race course overview table imitate *. A tunnel-like link 180 is provided in the recess I78 as a cover for the end 174 of the lever 168. This link 180 has an open forehead end 182, into which an open-ended projection 184 of the control unit 126 can enter. When the racing car 42 in the above-mentioned, shown in Figures 2 and 3, position the top wall of the aforementioned racetrack box is located, and the lever I68, as already mentioned, is raised, the Projection 184 of the control unit 126 are inserted into the open end 182, whereby the extension 175 of the lever 168 acts on a reset mechanism 186 which is provided in the control unit 126. The reset mechanism 186 has a plate 188 with a first portion 190 »which is mounted displaceably in the control unit 126 in a first plane and a second section 192 which is displaceable in the control unit 126 lies in a second, lower level. The two sections I90 and 192 are through a vertical Transition pieces 194 connected to one another. The first or upper section I90 has an end I96 with a rectangular tongue 198 on, which in the, provided with an open ended, projection 184 protrudes · This tongue 198 is due to the extension 178 of one end of the lever 168 is gripped in order, as in FIG is shown to move the plate 188 against the tensile stress of the spring 200 to the left, one end of the spring 202 with the Plate 188 and the other spring end 204 connected to housing 128 is" ... ,..".,,-..

The reset mechanism 186 also has a trigger or a pawl 206 which is pivotably mounted on a screw 208 in the housing 128 and has a first tooth 210 which can come into engagement with the said vertical transition piece 194 to the plate 188 in it In this position, a cam 212 (FIG To close the circuit to switch 74 via contact 70 a, line 70 and sliding contact 61 , which is connected to said contact by a line 224 "The sliding resistor 62 is then effective for monitoring the speed of the car 42"

When the reset mechanism 186 is triggered, pulls the spring 200 moves the plate 188 to the right into the position shown in FIG. 6, in which the cam 212 on the end 225 of the Leaf spring 216 acts and brings this into contact with the contact to a circuit directly through the leaf spring 216 to Line 70 to close · This process creates full resistance of the coil 68 placed in series with the carriage 42, whereby the Car speed reduced to creep speed and thereby the operator of the racing car receives a signal to pull it into Box I50 for repair or maintenance » The sliding resistor 62 can only be made effective again in this way and the racing car again at full speed record by placing the plate 188 in its original position

again, which happens because the leaf spring 216 the contact 222 touches again and the sliding contact 61 back, is included in the circuit of the Ifagens 42. The circuit of the mentioned racing car can be done by moving the sliding contact 61 to be completely interrupted on an insulating piece 68a of the coil 68 «

The plate 188 only moves to the right after the pawl 206 is disengaged from the vertical transition piece. The latch 206 passes by the _(released in the shown in the Figure 6 position in which the pawl on the back of a, provided at one switching wheel 228, nose rests. The switching wheel 228 is rotatable by a bolt 230 mounted in the housing 128 and has teeth 232 which can engage a first switching nose 234 which is attached to said sliding contact 61 by a shoulder piece 236 carried by a column 138. Therefore, each time the operator of the Racing car hZ actuates the sliding resistor 62 by moving the button i42 to the left with his finger in the saddle-like recess, as can be seen in FIG. 7, the shift nose 23 ^ in engagement with one of the teeth of the shift wheel 228 and cause this wheel to be rotated counterclockwise by one tooth pitch, as shown in FIG.

If the button 1 ^ 2, as shown in Figure k , is moved to the right, the switching nose 234 slides over the next

lying tooth 232 away, so that said switching nose is able to turn the switching wheel 228 counterclockwise as soon as the button i42 is moved to the left again in order to reduce the carriage speed. After completion of a full revolution of the switching wheel 228, the nose 226 hits a counter nose 242 provided on the pawl 206, so that the said pawl around its. Pivot 208 is pivoted in such a way that the nose 210 of said pawl releases the vertical transition piece 194 of the plate 188 and the plate slides under the action of the spring 200 to the right, as shown in Figure 6, whereby the leaf spring 216 is released and the circuit at contact 222 opens. As a result, the full resistance of the coil 68 is switched on in the circuit, so that the speed of the racing car 42 is reduced to crawling speed. The operator of the car must then wait until it, as a result of the full resistance, slowly rolls forward to the racetrack box 150. Thereafter, the operator takes the car from the track and bring it to the said box is in position to actuate the lever I68 '· after which the end 184 of the control unit is sufficiently put into 126 well into the opening 182 so that a clamping Ring I84a on end 184 of control unit 126 engages member 180 and pushes extension 175 of lever I68 onto plate 188 and shifts it to the left, as ^can be seen from FIG. If the pawl 206 is still in the position shown in FIG. 6 at the time of the displacement of the plate 188 to the left, the lug 210 cannot again be behind the vertical transition piece 194 and the plate 188 cannot be clamped

Hold position. However, the operator will react naturally of a racing car after reducing the car speed may be in the operation of button 142 in an effort to do the To increase the speed of the car again. Such an actuation results in a further forward step of the shift wheel 228, whereby the nose 226 comes out of engagement with the counter nose 242, the pawl 206 is released, which under egg action a torsion spring 242 surrounding the screw 208 re-engages the vertical transition piece 194, as "es Figure 4 represents. .

It may be true that the operator of the racing car 42 is too will try to avoid starting up in front of a racetrack box by driving your car at a medium, even Speed continues the race and thus an actuation of the button 142 proves to be unnecessary. Hence it is for one of ordinary skill in the art will recognize that the shift wheel 228 is preferably operated by a means such as e.g. To keep cars in the running * However, it should be noted that some Toy racing car systems do not use steering controls. In these systems belonging to the state of the art, the means described above for actuating the Shift wheel 228 through the button 142 its special application » This remedy can either be discontinued if the Sehalt-228 monitored by the control mechanism or it

Such a measure is achieved by the lever mechanism generally designated 246 in FIG can get. The plate 248 is pivotably mounted on a pin 252 in the housing 128 and has a ^{; J} * rounded end 254 with arms 256 and 258, which protrude spread in front of a control pin 89. In addition, the plate 248 has an upwardly projecting pin 260, which lies with its end face against the cover wall 13Ο, in order to hold the plate 248 in its seat within the housing 128. A triangular plate 262 is attached to the control pin 89 and takes part in its rotation so that the plate 262 can come into contact with the surface 264 'of the plate 248 in order to keep its rounded end 254 in engagement with a tab 266, which is also firmly seated on the control pin 89. When the steering wheel 88 is rotated counterclockwise, as shown in Figure 7, the tab 266 presses against the arm 258 to pivot the plate 248 about its pivot point 26Ο in such a manner that the indexing tooth 25Ο slides over a tooth 232 of the indexing wheel 228 into a position and said indexing wheel is adjusted by one tooth pitch as soon as the control wheel 88 is next turned clockwise so that the tab 266 presses against the arm 256 As a result, the shift wheel 228 shifts

in the plate 188 provided hole 27O is supported. The pin 268 is normally kept out of engagement with the hole 27Ο by the bias of a compression spring 272, one end against the head Z ^ h of the pin 268 and the other end against the surface of the cover wall of the control unit 126 A locking member 276 prevents the pin 268, which is under the tension of the pressure spring 272, from jumping out of the control unit 126. The pin 268 can be pushed down into the hole 27Ο and thereby prevents the Plate 188 moves into the position shown in Figure 6, even if said plate is released by the operations described somewhat above. The pin 268 is held by friction at the end in the hole 27Ο
