Band and station selection device for radio receivers

The invention "relates to a belt and station selection device for broadcast receivers with a variety of presettable station pushbutton buttons connected to a tape storage arrangement work together for a specific band setting.

Station selectors for radio receivers with push button: _i , button station selectors and one; Tape storage arrangements have already been proposed ί, οο-PS 133 912). These devices comprise a tape storage arrangement which is rotatably arranged on a linearly displaceable guide plate. When the station pushbutton is pulled out, the memory element is brought into a specific position corresponding to the selected frequency band with the aid of a finger. By later pressing the station push button, the re-setting of the desired frequency band is guaranteed by the position of the memory element.

This tape feeder arrangement works satisfactorily, if the desired frequency band is already set. However, the setting of the memory elements is as desired Frequency band awkward because the station pushbutton is pulled out the adjustment of the sliding plate assigned to the frequency band position is not possible. Rather, it must first the station pushbutton must be depressed so that an adjustment of the guide plate is possible.

It is an object of the invention to overcome this disadvantage and to provide a tape storage arrangement for push-button actuation To create station selector for radio receivers in order to pre-program stations in two different ways Frequency band ranges even when the station pressure is pulled out., Enable button buttons.

This object is achieved according to the invention in that the band storage arrangement comprises a band switch, which can be adjusted to one of two different frequency band settings as a function of a specific station push button provided at the front end, running in opposite directions and in a first and second frequency band position pivotable • that an operating rail running from the respective pushbutton is provided with a finger that comes into engagement with the memory element when the pushbutton is withdrawn in order to pivot the memory element into either the first or second frequency band position and, depending on the actuation of the band switch, into a specific frequency band position, and that with the individual push-button buttons each guide element ducks are connected, which come into engagement with the associated memory element in such a way that the band switch when the push button is pressed

On the storage disk 28 are a plurality of storage elements 44 ζ.3, rotatably mounted with the help of a pin 42. In each case one storage element 44 is assigned to a push button 16. Each storage element 44 has a front end 46 with two outwardly extending in opposite directions Tabs 46a and 46b. A rounded recess 48 is provided between these two tabs. The tabs themselves are with a cam surface 47a and 47b avf of the front Mistake. The opposite end of a storage element 44 is designed as an arm 50 which tapers conically into a tip 52. Such a memory element designed according to the invention is shown in FIG. 4 shown in perspective.

The storage element rotatable about a point 42 in the area of the front end can zx ^ ischen two positions, namely the AM or PM position can be pivoted. This pivoting movement is in the respective end position by stops 5 ^ a or 54b, which are arranged so as to protrude upward on the sliding plate 28 and to which the arm 50 aes storage element strikes.

A wedge-shaped guide element 56 cooperates with the arm of the storage element and is arranged on the push button 16 so as to protrude downward. This wedge-shaped guide element prevents unintentional displacement of the storage element from one tape position to the other when the pushbutton is in its rest position, ie in a central position between two end positions. After ilerausz _w ^ flee the smooth knob from this position of rest, it is

net and either on one or another tab 45a or 4 £ b of the storage line comes to rest when the push button is pulled out. In any case, after the push button 16 has been pulled out in hex, the finger 60 finally assumes an end position and comes to rest in the rounded recess 48. If, for example, according to FIG. 5, the storage element assumes the position shown and is thus set to AI ^v i-3eurieb., When the pushbutton 16 is pulled out, the finger 60 comes into singular engagement with the cam surface T-7a of the tab 46a and pivots it Memory element clockwise around point 42 approximately in the figure in Fi £. 7 position shown. The subsequent pressing of the push button causes the wedge-shaped guide element 56 ει to slide along the edge 62 of the arm 50 and thus the sliding plate 23 into the position in which it was when the push button was pulled out to adjust the oil storage element .

If after pulling out the push button a 3and switchover is desired, this can be done with the help of the Schaltariues 1-3 by bringing it into the opposite switching position, with a simultaneous shift the sliding plate 28 takes place in the corresponding position.

Plate 28 is also not obstructed by the storage element 44 or the finger 60. This is through any shift of the sliding plate 28 only the storage element around the pivot point 42 pivoted, with the finger 60 remaining in the recess 48, so that it is possible to switch the band only to be done by first pulling out a push button and then pressing the band switch wxrd.

For a better understanding of the invention, a Functional description of the tape storage arrangement given with reference to FIGS. 5 to 8.

In Fig. 5, the storage disk 28 is shown in the AM position. It is now assumed that by inserting the guide element 56 and, through interaction with the memory element 44, an adjustment of the station selector to FM mode should take place, with that FM frequency set which corresponds to the AM frequency selected by the preset setting of the memory element. By Pressing the push button 16 according to FIG. 6 brings the guide element 56 with the stop edge 62 of the arm 50 in contact and slides along this arm 50 until it reaches the position shown in FIG position shown. As a result of this sliding along the arm 50, the sliding guide plate 28 is moved to the right and thus in moved the Wed position.

To change the station setting to a new station in on the other band, the push button 16 is moved from its rest position to the position shown in i'ig. 7 or 3 position shown sucked out. For the FsIl that the position & s storage element 44 and the Slide plate 28 corresponds to the position according to FIG. 5, the finger 60 comes to a stop on the tab 46a and rotates it Storage element 44 clockwise about the pivot point 42 to the finger 60 to lie in the rounded recess 48

723078430.11.72

comes. In this position, the sliding plate 23 can be displaced both into the AM and into the MI position according to FIGS. Whenever subsequently the push-button is pressed, the slide plate 26 remains in the selected position \ ie in the example shown in Fig · 7 case takes the slide plate 28, the All-position, whereas in the β in FIG = the illustrated case, the slide plate in the FIl position assigned location comes to rest. This last-mentioned switch to the FM position is indicated in FIGS. 5 and 6 and has already been described above. When the push button Ic is pressed in, the guide element 56 slides along the edge 62 of the arm 50 of the storage element 44 and moves the sliding plate 28 to the right into the FM position.

The new tape storage arrangement according to the invention offers the possibility of setting the desired band in a simple manner for push-button station selectors, the tape storage arrangement due to the simple Design both cost-saving to produce and very easy in the radio receiver because of the small space requirements is to be accommodated »Switching from one to the other belt can be very advantageous by pulling it out of the pushbutton for station selection without further adjustments being necessary on the pushbutton.
