Toy turntable

The present invention relates to a toy turntable, essentially consisting of a motor-driven sound carrier and a verochuenkbaren tonearm with a scanning needle, the vibrations of which are transmitted to a membrane.

There are already various toy sound reproducing devices which differ in shape, dimensions and mechanical systems. One feature is known to all Sound reproduction devices in common, namely doQ dia stylus does not immediately return to its starting position after playing the disc; this requires manual operation of a wide variety of devices.

It is obvious that a disadvantage of the systems mentioned lies in the fact that the playback needle moves towards its starting position Each playback must be returned manually.

This disadvantage is eliminated by the present invention and through cooperation on the one hand with a return spring, which constantly acts on the tonearm and the playback needle in the direction of on their output position and on the other hand by a gear

system, which opened on the day of the day, after the process of disconnecting the playback and the sound carrier from each other, so that the tonearm with the needle has the opportunity to return to its original position due to the effect of the aforementioned return movement. The drawings, FIGS. 1 bia h, are intended to explain the invention and its uses by way of example.

The automatic device of the toy recorder B causes as already described that after completion of the Abapielvorgangs the TnntrMgtirplatte from the l'JiudBrgabeeinrichtung gstrsnnt iuird and that the arm automatically returns to its Aungangspasition, whereupon the replay begins all over again. With reference to the Drawings the device works as follows:

The KlBinmatnr 1 drives the sound carrier disc G en by means of the transmission 2. This is constantly held in its obscure position by the pressure for 5 ". The sound carrier plate has a running ring on its upper side and is rotatably mounted on a foot-mounted axle This ten wheel has on its inner upper side an elevation 1 ^ as shown in Figure k .

Above the manned gear is another achae on the ctslben

opposite tiv.m other gear ,.

The gears 10 and 11 are non-positive via a common name Pinion verhundün, which to>? 3c! <MeiBig 12 tooth with adapted Has tooth shape. On this ülsiao is the rotation of the lower Gear 10 on dan gear 11 through that pinion 3 transmitted. Therefore, the direction of rotation of the gears 10 and 11 is the same. However due to the fact! that the gear 11 is one more tooth than the gear 10, there is a delay in the rotation of the upper gear with each revolution by one tooth. Therefore there will be a moment in which the elevations of both tens will face each other exactly.

As the rotary motion of the device goes outside, the bumps exercise pressure on each other causes the pinion 10 and the Tontrügerplstte from the gear 11 against the force the pressure foot no 5 being lifted off and together a lower position take according to the height surams of the surveys.

The Tanträgerplatto and the gearbox ·} are still driven, and as soon as the highest position of the elevations is exceeded, the spring 5 pushes the sound carrier plate and the drive gear wheel 10 back to their original position.

While the bumps on the 2 Z & hnrlldßrn cause this Move them away from each other while pressing down on the inner plate, the tonearm 12, which carries the playback needle, is its acits

Has contact with the overdrive plate U , to which the vibrations exerted grooves are transmitted, released and moved by the return spring 7 in the direction of the beginning of the sound transfer plate and stopped by the stop 9.

As already mentioned, the TontrügürplatttJ when the elevations have moved past one another, into its normal position through the Compression spring 5 pushed back. This process creates a new one Touching the tone grooves with the Nedol and the transmission membrane, whereupon the playback process begins again.

The playback cycle continues until the motor drive is interrupted by a switch. Switching on the device is therefore only ninnsal for an arbitrary number of Abspislvargangss according to the I '& llen tiss RGnutzers P-rforrierlinh.

The "duration of the AbspiBlvarQonga corresponds to the time that the gearwheel 11 is needed for as many complete rotations as it is Has teeth.

It must also be mentioned that the shape of the elevations depends on the

Cogwheels need not be strictly roof-like, but that other shapes are possible. The difference in the number of teeth of the two gears 10 and 11 is expediently one. However, it can be greater than one.
