Electrically or mechanically controlled coupling for radio »and television sets»

Description ;

In radio and television equipment it is often desirable to operate 2 different types of movement processes with a single rotary knob, for example 2 different dial indicators or variable capacitor drives independently; to move from each other »For this purpose, mechanical couplings have been developed which are designed in such a way that the button, when pulled out, couples a movement process, while when it is pushed in, it couples the other movement process, whereby the former disengages again. the most serious of which is that the shaft switch or push button system and shifting of the rotary knob have to be operated, which causes the

Device operation complicated.

The essence of the present invention is characterized ^ that the wave switch or the same ^ replace T.

In the figure are two embodiments of the present Invention illustrated »First of all, the exemplary embodiment with electrical Coupling of the movement processes described Bine shaft 1,

which is provided with a rotary knob 2 on one brew and is stored in any 5? ei3e, for example at points 3 and 4, has a flywheel 5 on its end and a flywheel 5 * On the shaft 1 sit the sheet metal magnets. β and 7 _t which are firmly connected to the shaft 1 »The current is supplied to these electromagnets through the slip rings 8 and 9 · Furthermore, on the skin 1 there are disks 10 and TT, which are designed as a cord roller and via the cords 12 and T3 are placed * which are the disks. 10 and 1t with the. Variable capacitors 14 and 15 connect ∆η to the cords 12 and 13, pointers 16 and 17 are attached »On (ken electromagnets 6 and 7 lead via the sliding contacts 8 and 9, lines 18 and T9 to switches 20 and 2t and via these switches to the power source 22 »The axis 1 and the iron housing of the magnets 6 and 7 as well as the one foil of the power source are connected to earth 23 ·

The operation of DET electrical coupling of the present invention is as follows

For example, it is desirable to set shortwave, mediumwave or longwave on the device »ie the dial pointer that marks these areas on the scale should be moved * In this case, switch 20 was closed and consequently magnet 7 was excited so that it moves with the disc coupling TT "by turning the button can now be of the variable capacitor are moved across disc TT cord 15 _r wherein dial pointer 17 travels also in the sighting line movement. Magnet 6 remains de-energized and, as a result, disk 10 moves.

is a key point of the present invention is that the switching he _r the achliessen the circuit to the magnet, in Ferbindung with the switch shaft of the device or IExt this to be set equal. Pushbuttons are available * d »h» by setting the wave switch accordingly or by pressing the button down. the corresponding push button closes the circuit and. the magnet is excited, the associated disk of which is connected to the variable capacitor via the cord »which belongs to the wave range in question» In the present exemplary embodiment, the switch would; 20 cause the magnet 7 to be excited in the closed state »whereby it is coupled to the disc ti · Since the magnet 7 is firmly seated on the shaft t, it is through. Turning the rotary knob 2 via the cord drive 13 moves the variable capacitor 1-5 »At the same time, the pointer 17 moves over the scale» The variable capacitor remains at rest »because in the switch position shown in the figure, no current flows through the magnet 6» If the switch 2t closed and switch 20 remains open, the opposite occurs, that is, the variable capacitor 14 is moved and the variable capacitor 15 remains in the low position. It is an essential characteristic; de? the present invention may be that inevitably entered into only one of the switches 20 or 21 · The present invention see not limited systems to those illustrated in the figure applies to 'two magnetic "but it is of course possible, on the same wave for several

Aa hand of Figure 2 is now an embodiment with mechanical coupling in connection with a push button system «

Bine shaft 1 which at one end provided with a knob 1st and? / Else _r example, art in any points * is stored for 3 and 4 »carries at its sin a flywheel 5" On this skins sits a cone 24 'of the The shaft is taken along in the direction of rotation * but is slidably mounted on the same.This cone 24 can be brought into a friction clutch during displacement: with a counter-cone 25 * which sits loosely on the shaft 1 but cannot be displaced in the axial direction Fork 2.6 * which is stored in point 27 and is connected to a pushbutton 29 by means of a rod 23.
