Band and station selection device for federal radio receivers

The invention relates to a band and station selection device for dog radio receivers with a variety of presettable Station pushbutton buttons with a sandpit arrangement work together for a specific band setting

Station selection devices for radio receivers with push button station selectors and a tape storage arrangement have already been proposed (UB-I ¹ B 135 912). When the Statlon pushbutton is pulled out, the storage element is brought into a certain position corresponding to the selected frequency band with the help of a pinger.By later bridging the ctation pushbutton, the re-setting of the desired frequency band is ensured by the position of the dea ^ pelchor element.

This band storage arrangement works satisfactorily when the desired frequency band is already set. However The setting of the memory elements to the desired frequency band is cumbersome, since a station push button is sucked out the adjustment of the sliding plate assigned to the frequency band position is not possible · Vielmohr muss sunäehst the station pushbutton must be depressed so that an adjustment of the sliding plate is possible.

The invention has the task of overcoming this disadvantage and a tape speloher arrangement for pushbutton actuated Create station selector for radio receivers, to pre-program stations in two different frequency band ranges, even with station pressure drawn out, enable button buttons *

According to the invention, this object is achieved in that the tape cover assembly comprises a tape cover, dor in Dependency on a specific station push button in one of two different frequency band settings adjustable is that a memory element interacts with each of the pushbutton buttons, including one around a threatening point A swiveling arm with two at the front end, in in the opposite direction are provided with leading tabs as well can be swiveled into a first and wide frequency bath position that an actuating rail with a finger, which runs forward from the respective pushbutton, is provided with the memory element when you return the pushbutton comes into engagement to the Speiohemlement in either the first or »wide Frequensbandpoaitlon and depending on the Actuation of the band holder in a certain frequency band position swivel au, and that with the individual pushbutton buttons each guide elements are connected with the specially ordered F> peloher element come into engagement in such a way that that the strap holder when you press the push button

displaceable in a certain desired frequency band position is.

Further features and refinements of the invention are the subject matter of subclaims.

Due to the inventive design of the belt and station selection system, it is possible to create a belt storage arrangement which works very simply and appropriately and only insignificantly influences the manufacturing costs for two-belt bundles. A preferred embodiment of the band storage arrangement comprises a sliding plate as part of a band switch, which is displaceable from one side to the other and in the two end positions allows the radio set to be set to two different frequency bandwidths, EB Im AK-br, w. FH operating represents · In ά. · Τ slide plate are arranged in a plurality of storage elements rotatably, each station pushbutton key is assigned a memory element. These storage elements have at the front end of an elongated arm flaps designed like wings, whereas the rear end of the arm is designed in such a way that it can interact with buckets of wedge-shaped guide element. This push-button element is attached to the station push-button button. Furthermore, a finger is arranged on the station push-button button, which interacts with the middle and the memory element5 when the operating button is pulled. Bas storage element is for ·! can be swiveled around the finger to both sides if the belt is to be switched when the station pushbutton case is pulled, without the pushbutton having to be pressed further. After setting the station, the ^ tatlons push button button is pressed, whereby the storage element remains in the position characteristic of the selected frequency band.

In ligaments 2 and 3, a preferred embodiment is the Bandepelcherungsanordnung 26 shown as it is in the dog * radio receiver 10 can be used.

The tape storage assembly includes a slide plate 28 »die inside the housing 12 in a plane below the push buttons 16 can be moved sideways. In Fig. 2 only a push button 16 is shown * The sliding plate 28 is according to 5 to 8 provided with longitudinal slots 52 into which Engage pins 30.

simple form shown to explain the mode of operation have buss, but according to the usual practical There are a number of electrical and mechanical switching devices that are required for switching from AK to FH operation.

On the storage disk 28 are a variety of storage elements 44 see.B · mounted rotatably with the aid 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 bwei running outwards in opposite directions Tabs 46a and 46b. A rounded recess 43 is provided between these two tabs. The tabs themselves are with a cam face 4? a and 47b on the front Mistake. The opposite end of the storage element * 44 is designed as an arm 50 which opens conically into a tip 52. Such a storage element designed according to the invention is in Flg. 4 shown in perspective.

Bas rotatable about a point 42 in the area of the front end The storage element can be swiveled between two positions, namely the aft or flW position. Tuck swivel movement is Ia the respective end position by stops 54a or 54b, which protrudes upward on the sliding plate 23 are arranged and to which the arm 50 of the storage element adjoins.

On the arm of the spelcher element, a wedge-shaped guide element 56, which is attached to the push button 16 1st arranged protruding downwards. This wedge-shaped guide element prevents unintentional displacement of the storage element from one tape position to the other, when the push button is in its rest position, i.e. in a middle position between two end positions, laugh it is when the push button · »is pulled out of this rest position

possible to adjust the station frequency selectable by the push button, with between the wedge-shaped guide element 56 and the rear end of the arm 50 given enough leeway is so that the storage element from the AM position in the FM position or vice versa is pivotable.

With each of the pressure knobs 16 is an "actuating rail 58, from which a finger 60 extends downwardly _f in a certain distance from.! Guide member 56 is disposed either on / exnen or other flap 46a, 46b of the memory element to the plant comes when the push button is pulled out. In any case, after pulling the push button 16, the finger 60 finally assumes an end position and comes to rest in the rounded recess 48. If, for example, according to FIG is set to AM mode, the finger 60 comes into engagement with the cam surface 47a of the tab 46a when the pushbutton 16 is pulled out and pivots the memory element clockwise around the point 42 approximately into the position shown in FIG of the push button causes the wedge-shaped guide element 56 to slide along the edge 62 of the arm 50 and thus the sliding plate 28 into the Shifts the position »in which it was when the pushbutton was pulled out to set the memory efficiency.

If you want to change the band after pulling out the push button, this can be done with the help of the switch arm 13 accomplish by placing this in the opposite direction Switching position is brought, at the same time a displacement of the slide plate 28 takes place in the corresponding position. There after pulling out the push button 16, the memory element 44 is pivoted about its pivot point 52 that the Finger 60 comes to rest in the rounded recess 48 between the two tabs, the displacement of the sliding
