PATENT OFFICE.

The present invention relates to a device for remote control mechanically or electrically driven derailleurs, as they are used several times in practice, e.g. B. for cell switches for accumulators with high amperage, for driving the rudder on ships, for Elevators and the like can be used.

Just like the devices that have become known so far, which serve the same purpose, the new device consists essentially of two parts: the control switch, which can be placed at any location, and an interrupting device, which is moved by the switching mechanism to be operated itself, i.e. in the immediate vicinity of the same must lie. The control switch and switchgear each have a series of corresponding ones Contacts. With the latter, the interruption device cooperates in such a way that after an adjustment of the Control switch the switching mechanism moves into the appropriate position and then in this is automatically stopped.

With the new device there is now a switching device with the crank of the control switch connected, which according to the direction of the rotation of the control switch current through the clockwise rotation or another, the left-hand rotation of the rear derailleur causes the coil to flow. At the same time there is one with. to the:

Switching mechanism synchronous interruption device provided, which the line to the contact switched on in the control switch is interrupted as soon as the switchgear activates the corresponding Position reached.

On the accompanying drawing is an embodiment of the new device for remote control represented by cell switches.

The device of D. R. P. 129290 is the inventor's drive mechanism for the cell switch drawn schematically.

Only those necessary for understanding the present invention are shown in the figure Parts shown, while all not absolutely necessary have been left out.

α and b are two magnet coils. If a is excited, the drive motor omitted in the drawing is switched on in the sense that the slide c of the cell switch goes upwards. On the other hand, if b is excited, the slide c goes down.

The drive device described in the patent mentioned above is indicated by the rings de, the fixed contact f and the two movable contacts gh. It works in such a way that the switch of the motor is kept closed even after the contact initiating the movement has ceased. Depending on the contact h or the contact g with the. Circles d comes into contact

Claims (1)

the motor causes it to turn to the right or to the left, ie to move the carriage c up or down. . The excitation of α or b occurs "by the device i attached at any point. The contacts k ¹ to k ^{6 of the} same are connected to the circuit springs Z ¹ to Z ⁶ on the cell switch. Furthermore, the control lever i has an arm that is conductively connected to it q , which can be rotated with strong friction on i . Its movement is limited by the two stop pins r and s . This lever q slides on contact t and u; t is connected to coil α , u to coil b. C to the contact a sled cams ρ, or the like. Fitted, which in the illustrated rest position of the slide corresponding to the turned-on cell switch Contact spring c Z ³ of the platelets O ² and O ³ stands out. If you follow the course of the current from the negative pole of the power source, you first arrive at the connection point of the coils a and b. From coil b you get to h and via m to η \ h and η have no further connection. So only the route via a, n, t, k ³ to Z ³ comes into question. Z ³ is lifted from o ² and o ³ by the lug ρ , so the path via α is also interrupted, so both coils α and b are not energized. If you now set the contact i to k ^e , q remains at t , the current runs from the negative pole via a, n, t, q, i, & ⁶ , o ⁵ to the positive pole. Coil α is excited and, as mentioned above, generates an upward movement of the slide. ^{Z 4} , Z ⁵ and Z ^{6 are} lifted off one after the other. As soon as Z ^{6 is} lifted, the circuit of the switch i is interrupted, the excitation of α ceases and the carriage c stops. If one now goes from k ⁶ to k \ , q is carried along to η. The path of the current through coil α is now interrupted at t (the dotted position of i and q applies), whereas the current through b, m, n, q, f, A ¹ , Z ¹ , o ^{1 can} move towards the positive Pole run. So coil b is excited, which brings about a downward movement of the carriage. This continues until Z ^{1 is} lifted from o ¹ and the current in coil b is interrupted as a result. The carriage c follows the movements of the contact i exactly. When the device is at rest, the position of i shows where the slide c is and the position of q shows whether it was previously higher, i.e. last made a downward movement (q to n), or whether it was lower, i.e. a has made an upward movement (q to t). Pate ν τ-Α ν SPRU c η: Device for remote control of mechanically or electrically driven switchgear with automatic shutdown by means of an interruption device running at the same time as the switchgear Direction after the switchgear has been set according to the position of the control switch, characterized by an inevitable with the crank of the control switch which determines the end point of the movement of the switching mechanism connected switching device, which according to the sense of the rotation of the control switch current through the movement of the rear derailleur in one sense or another lets the introductory coil flow.
