In Fig. 1 the cam 30 is from right to left the radio by hand to another desired moved so that the bent sections 34 and 35 station tune. Rod 49 comes for example Cam 30 on sections 37 and 39, when engaged with the connecting pin 60 of the key slider 22 rest and this is set in its the key guide 22 and the press lower layer in frame 24. In Fig. 2, 5 cam 30 is located in its upper position. Pulls the cam 30 is pushed from left to right, if you push a button 13 outwards, the move that its bent portions 34 and 35 are two parts 63 and 64 against each other so that the cam 66 is released below the arcuate portions 38 and 40. The button 13 is then are located, so that the key slider 22 is pressed in its upper inward until the cam against the Position in the frame 24 is pressed. There is io double lift mechanism 42 butts and engages on it the key slider in the lower position, as Fig. 1 aligns.

He has an AM tuning unit 20 24 in the upper position. Because the key glider 14 and an FM tuning unit 16 which, as shown in FIG. 4 47 is stored within the key guide 22 is shows, are arranged one above the other. About which he is also lifted up and moves the Manual tuning button 19 or the pushbuttons 12 is pin 60 in the passageway that goes through with each other actuated a double lever mechanism 42 formed with slots 58 and 59 aligned until between the AM and FM tuning units, the pin 60 is located within the slot 58 of FIG so that both tuning units rod 49 is located during its movement. When you press button 13 can be set at the same time. The mode of operation press the key slider 47 and the pin 60 against this tuning unit is, for example, in the wall of the slot 58.

In this way, only one channel 52 or 53 is required on the push button facing the button in order to end the receiver with a groove 55 or 56, which runs perpendicular to the 50 to tune to AM and FM transmitters , and a groove 58 or 59 between which only the cam mechanism 30 between the ends of the channel, which must also be moved perpendicular to it of the AM and the FM position. runs.

There is one to prevent the tuning die Pushbutton in its rest position, the 55 mechanism is built in for the event that the Grooves 58 and 59 of the channels 52 and 53, respectively, operate the push-button setting on one aligned and form a passage for the other transmitter wants to change.

According to FIG. 3, each of the rods 49 and 50 has been positioned, and the pin 60 engages in the slot 58 of the mutually movable sections 63 and 64 and 6a rod 49. To set the pushbutton on adjustable cams 66 and 67, each of which is pulled outwards between different FM transmitters, see the two mutually movable ab- so that the pin 60 cut against the wall of the slot 63 and 64 in a known manner Way lockable 58 pushes and the rod 49 is moved outward. The cams 66 and 67 butt against the double lifting mechanism 42 sliding in the channel 52 of the rod 50 when the button is pressed 65. This causes the sections 63 and 64 to move and place the tuning elements on a front rod 49 against each other and enter the cam set station. 66 free, so that he can focus on the new position of the double

This station can be changed by adjusting the lifting mechanism 42. Presses

if you then continue to press the key, the two parts of the rod 49 move against each other again and block the adjustable cam 66 in the new position, but there is the possibility of moving the cam 30 from left to right so that - dfe: button guide 22 is lowered and with it the button slide 47 and pin 60. If the button is still pulled out, however, the slot 58 of the rod 49 is aligned with the slot 55 at the end of the channel 52 so that the aligned slots form a passage (Fig. 7b). When the cam 30 is moved, the pin 60 is therefore pressed into the channel 53 of the rod 49 (Fig. 7c). If the button is now to be pressed inwards, in order to lock the adjustable cam in the new position, the pin 60 presses against the wall of the slot 55 in the rod 50 and tries to push this rod inwards towards the double lifting mechanism; however, the pin 60 only slides in the channel al 53 of the rod 49 until it hits the end wall of this channel (Fig. 7d). When this occurs, the pushbutton is held in place and cannot be depressed any further so that the tuner cannot jam.

The F i g. 8-10 illustrate another embodiment of the invention. Here the Key 70 has an extended portion 72 fixed in the key guide 22 of the first embodiment and acts as a key glider. The key slide 72 is hollow and has two connecting pins 75 and 76, which are arranged opposite one another on the top and bottom of the key slider. Two Rods 78 and 79 are arranged side by side in the receiver and protrude into the hollow key slider 72. The rods 78 and 79 each have a recess 80 and 81 at their ends. The recess 81 the rod 79 opens down into the lower edge 86 of the rod 79 while the recess 80 in the rod 78 opens upwards from the upper edge 85 thereof.

In operation, the cam 30 is moved from right to left, the key guide 22 lowers and engages with the connecting pin 76 in the key slider 72 in the recess 80 of the rod 78 Therefore, actuation of the button pushes the pin 76 against the wall of the recess 80 and moves the Rod 78 forward until the cam 83 hits the double lifting mechanism 42 'and that Tuning element 14 sets to a predetermined station.

If FM operation is desired, the cam 30 is moved into the FM position in which the key guide 22 and the key slider 72 are at the top, so that the connecting pin 75 in the recess 81 of the Rod 79 engages. When the button is actuated, the rod 79 is then moved until the cam 84 pushes against the double lifting mechanism 42 'and the FM tuning element 16 to adjust the Radius changed to a predetermined FM station.

The improved push button tuner has only one set of buttons, its individual buttons first and second tuning elements for tuning the receiver to preset stations in different Adjust the wavebands.

The position of the cams 83 and 84 can be changed by placing pins 75 and 76 in corresponding ones Recesses 81 and 80 of the rods engage and, by pulling on the buttons, engage the cams to unlock in the same way as in the embodiment described first.
