The present invention relates to an electrical side control device, in particular to a electrical timing device with improved performance and simplified structure in which the Zeitbagrensungsschaltmschanieinns or switching delays ™ rungsmechanianiUQ after the desired time has elapsed so operated. That the driven by a motor Drive pinwheel with the driven gear through

the action of an electromagnet is brought into engagement.

Various types of timing devices have been proposed to date. A kind of is designed, for example, so that during the constant drive of the drive gear by the motor the rotational force of the drive gear is transmitted to the driven gear due to the coupling action in cooperation with the electromagnet and that immediately after the driven gear rotates at a certain angle of rotation, i.e.-at the end of the predetermined time, the switch delay mechanism operates to control an external circuit will.

In a timing device of this type, it is necessary to control the power transmission from the motor to the driven gear after the expiry moment in which the Shutter delay mechanism is actuated, to under » break. If this process of interrupting the power transmission is neglected or omitted, an unacceptable load acts on the fco tor, which can lead to breakage of the timing device or to failure of the drive or driven gear. ;

Two conventional types of timing devices have also been proposed using means which are not subject to the action of a prevent a portable load on the engine 3 a it is designed in such a way that the electrical current is supplied to the motor immediately after the stopping moment can be interrupted while the other eo

is placed, άεο the electrical power supply to the electromagnet can be interrupted immediately after the expiry torque to the drive gear inevitably out of mesh with the driven gear bring.

The conventional type of timing device mentioned first is broadly accepted as it is technically reliable and errors occur less frequently. However, it has the disadvantage that the dimensions of the timing device are increased significantly by the fact that an additional switching mechanism for interrupting the power supply to the motor and a to operate the additional switching mechanism necessary large electromagnets are provided need what 2> ~. an increase in manufacturing costs leads.

On the other hand, even in the second-mentioned conventional type of timing device, it is necessary to to provide an additional lever to interlock the drive gear with the driven gear to disengage, which not only leads to a cumbersome m construction, but as with the A timing device of the first mentioned type makes larger electromagnets required.

Wae was necessary in connection with the time control devices generally available up to now, is an additional switching mechanism for interrupting the electrical power supply to the motor or Electromagnet, and this additional switching mechanism is - either built into the time control device or in an external consumer control

Circuit (load control circuit) arranged, which is to be actuated by the switching mechanism of the time control device for controlling the consumer control circuit. In the first-mentioned phase it was necessary to provide not only the shift delay mechanism in the side control device, but also the additional shift mechanism, so that an increase in the dimensions of the device was unavoidable, since a reduction in the dimensions led to a reduced shifting capacity of the two shift mechanisms. W ron would. In the second case, for the purpose of controlling the time control device through the additional switching mechanism provided in the external consumer control circuit, it was necessary to connect the time control device to the external consumer control circuit, which makes the construction of the time control device and the external consumer control circuit more complicated.

The aim of the present invention is to provide a timing device in which the above-mentioned additional switching mechanism to interrupt the fe power supply to the motor or iSlektromagneten at the moment the set elapsed time in the weeentli * is switched off.

In the timing device constructed according to the invention let in a Uofasgeahaohnltt with the Drive gear driven into engagement su bringing Gear a toothless Absohnitt provided in the form of a Aueeparung, in which the drive gear in the The moment the previously set time elapses is reduced, thereby preventing the motor from being overloaded.

In detail, the timing device according to the present invention comprises a drive device, a drive device, a drive gear driven by the motor, a driven gear which is provided with a toothless recess in which the drive gear can releasably engage, an electromagnet, which causes the Antriehszahnrad with the driven gear by the Kupplungswir effect in and is brought out of Singriff, and a time delay mechanism for controlling dee external load control circuit, wherein the switching a deceleration mechanism in the discharge moment in connection · hang with the rotation of the through KupplungBwirkung with dom drive wheel in Blngriff stationary driven gear is actuated, after which dB »in the recessed section of the driven gear · located drive wheel runs in idle gear.

As described above, the timing of the present disclosure is simply constructed, since the circumference of the driven gear is provided in a recessed section, on which the drive gear driven by the motor engages and which it can sink in order to transmit power from (interrupt the drive wheel to the driven gear, see below. Therefore, the electromagnet to be built into the side control unit can not only be reduced in size and an excessive load on the motor can be avoided, but the timing unit can also be produced at low cost.

bination with the switch delay migsmeehaniamua, the an essential part of the previously generally available Timing devices was, in the present Invention has been turned off, so what can now the technical idea of creating a combination of two switching mechanisms of some kind of timing device concerns - those mentioned two switching delay mechanisms for controlling the corresponding Number of external consumer control groups to be set up. On the other hand, only one of the two switching mechanisms can be used for the same purpose be provided, while the other to maintain the battery-excited state of the electromagnet is used during the expiry of the previously set time. Such alternatives have been used in the timing device of the invention.

Further, in a currently available conventional ZeitBteuereinrichtung the releasable engagement "will wipe the driven from ISotor drive gear and the SchaltverzögerungenechanismiB actuating driven gear in connection with the operation of the electromagnet through a 'connection part., Such * as an additional, between the power transmission shaft and a movable iron part that works together with the electromagnet). Furthermore, the actuation of the switching mechanism is coupled to the rotary movement of the driven gear. In this arrangement it has proven to be unfavorable that the connecting part covers a relatively long distance and the switching mechanism works through many intermediate parts inserted between the electromagnet and the driven gear, which leads to a delay beyond the intended time.
