, Claims priority, application Germany November 24, 1955 2 Claims. (Cl. 46244) operating current is fed by means of electric wires to the driving motor ,firmly mounted in the toy. For carrying out control functions a step-by-step switch is located in the toy and, on the rotation of this switch, different control operations are initiated by means of cams or eccentrics or even by a contact drum. The step-by-step movements are effected in the known constructions by the armature of a particularly strong and current-consuming .electromagnet in view of the necessary control forces, which electromagnet is energized from the source of currentover additional leads. The step-by-step electric switching mechanism constructed in this manner, which is similar to that used in electric railways, is very expensive to produce and of considerable weight, which may be advantageous in the case of railways but is nevertheless a disadvantage in the case of railless toy Vehicles. Another serious disadvantage is the necessity of providing electric transmission means with more than two wires,

. all the more since, particularly in the case of battery drive,

current superimpositions are practically impossible to effect, .and also many contact, insulation and soldering .points are necessary both in the .toy and also in the hand The known constructions of :this type .of toy could not be introduced on the-market on account of their high cost of production and their great sensitivity and also.

could not be mass-produced, although the particularly great fascination and unlimited possibilities of such toys were very well known.

The invention sets out to overcome these objections and difficulties inherent in the known constructions and to produce a driving and switching arrangement especially for an electrical remote controlled toy, which is so designed that an electric switching magnet or other additional electrical equipment is rendered absolutely unnecessary and wherein the remote transmission means are restricted to an ordinary commercial two-strand cord.

It is, therefore, the object of the invention to provide a double-acting driving and switching arrangement for toy vehicles, and especially for land, water and aircraft simulating toys provided with remote control.

Hence, the invention is based on the idea of employing an electric driving motor already existing in the electric toy, at the same time as a switching motor, for example by utilizing a counter-torque for providing the power for the switching arrangement in the form of a stepwheel.

In putting the idea into effect this can be attained,

2,923,092 Patented Feb. 2, 1960 for example in the case of a toy vehicle, by so arranging the housing of an electric motor in the toy so that it is not rigid but rotatably mounted preferably in a ball hearing on a drive pinion side and in a trunnion coaxial with the armature shaft on the opposite side and affording an angle of oscillation of only about to the housing to be sufficient for the housing to move through in order to efiect a switching operation.

According to another feature incorporated in the inventive idea, namely to use the driving motor also as a switching motor, the motor can be arranged in a particularly advantageous manner so that the housing of the motor does not rotate in a stationary position but the whole motor carries out a relative swinging movement.

Other features and characteristics of the invention are explained in the description of the drawings which illustrate only by way of example but without any restriction thereto preferred forms of construction of a doubleacting electric driving and switching arrangement provided in a remote controllable toy vehicle in the form of a motor car. In the drawings:

Fig. 1 is a top plan view of a double-acting electric driving and switching arrangement with rotatable motor housing;

Fig. 2 is a side elevation of Fig. 1;

Fig. 3 is a section on line I1IIII of Fig. 1;

Fig. 4 is a top plan view of the double-acting electric driving and switching arrangement, with the motor being pivota'ole in a cradle or stirrup;

Fig. 5 is a side elevation of Fig. 4, and

Fig. 6 is a cross-section on line VIVI of Fig. 4 with the swing stirrup in vertical position.

As can be seen from Figs. 1 to 3, the whole driving and switching arrangement is mounted on a base plate 1 in bent-up lateral flaps of which a housing 2 of an electric motor with armature shaft is mounted in such a manner that it is rotatable on one side in a ball bearing 3 and on the other side by means of a journal pin 4 coaxial with the armature shaft. A drive pinion 5 imparts its torque through an intermediate wheel 6 to a toothed wheel 7 which is rigidly connected with a driven runner wheel 8. The motor housing 2 carries a crank pin 9 on which a driving rod 11) is mounted which is slidably guided in longitudinal direction at its free end in a slot provided in a bent-up fiap 11 of the base plate 1. For the purpose of limiting the control movement, the end of the driving rod 10 has a recess 12 which in moving from one end position to the other allows a step wheel to be turned through one tooth. This turning movement is effected by a blade spring 14 constructed like a pawl and riveted on the driving rod 10. A toothed step wheel 13 is freely rotatable on a bolt 15 riveted on the base plate 1. A tension spring 16 riveted on the base plate 1 serves for arresting the step wheel 13. The step wheel 13 has an eccentrically arranged pin 17 which is connected with a cross-member 19 by means of a steering rod 18.

Fig. 1 shows the position of the steering mechanism for straight ahead travel. By means of the step wheel 13, which is provided. with four steps or teeth, the following steering positions are set in succession: straight ahead, right turn, straight ahead, left turn. in Fig. 2 the condition for straight ahead travel is indicated by solid arrows. As will be apparent therefrom, the drive pinion 5 of the motor rotates in clockwise direction and the counter-torque acting on the housing 2 presses the driving rod 10 into its forward end position. A momentary polarity reversal of the motor first causes a momentary change in the direction of rotation of the housing 2 to the direction indicated by the dotted arrow and results in the driving rod 1? being forcibly brought back into its other end position and consequently the turning of the will only act as a driving motor. a

In the embodiment shown in Figs. 4 to 6, the motor of the double-acting electric driving and switching arrangestirrup 20 is oscillatably mounted in lateral bent-up flaps.

of the base plate 1. The swing stirrup 20 carries below the pivot point a crank pin 9 to which the driving rod 10 is hinged. The pivot pin 22 serves at the same time as journal for the intermediate wheel 6 permanently meshing with the drive 'pinion 5 of the motor. The driving runner wheel 8 is driven by the intermediate wheel 6 and the gear wheel 7 which is connected with the runner wheel.

This arrangement operates in the following manner:

When the current is switched on for rotating the drive pinion 5 in counterclockwise direction, this pinion rolls on the intermediate wheel 6 which, due to the startingup resistance, must beconsidered as stationary at first. The motor, after planetary movement around the intermediate wheel 6 in the direction indicated by the dashed arrow, assumes the extreme or end position determined by the recess 12 in the driving rod 10. Only then does the vehicle start moving, the intermediatewheel 6 and its other extreme or end position, which movement, in-

dicated by the upper arrow, turns the step wheel one tooth through the intermediary of the driving rod 10. Thereby the advantageous condition is established that the direction in which the motor swings and the direction of rotation of the intermediate wheel 6 still maintained by the movement of the vehicle are the same, which has a very favorable effect from the point of view of forces. On the polarity reversal being removed, the pinion 5 brings the motor back into its initial position, when it 1.
