Am Steg (1a) der U-förmigen Trägerschiene (1) sind die hohlen Drehknöpfe (2) drehbeweglich befestigt, die an ihrem inneren Ende mit einem Kegel- zahnkranz (2a) versehen sind. Diese stehen in Eingriff mit den in glei- cher Weise geformten Kegelrädern (3Y, die an der Innenwand (1b) der Trägerschiene drehbeweglich gelagert sind. Mit den Kegelrädern (3) sind die Gewindespindeln (4) fest verbunden, auf denen die mit Muttergewinde versehenen Schleiferträger (5) durch Drehen der Spindeln axial verscho- ben werden können.The hollow rotary knobs (2), which are provided with a bevel gear rim (2a) at their inner end , are attached to the web (1a) of the U-shaped support rail (1) so that they can rotate. These are engaged with the molded in the same way bevel gears (3Y, which are rotatably mounted on the inner wall (1b) of the carrier rail. With the bevel gears (3) the threaded spindles (4) are firmly connected, on which is provided with nut thread Grinder supports (5) can be moved axially by turning the spindles.
Die Drehknöpfe (2) und die Kegelräder (3) werden nach einem anderen Vor- schlag an der noch nicht abgewinkelten Trägerschiene angespritzt, wo- bei auch die Gewindespindeln (4) gleichzeitig in die Kegelräder einge- spritzt werden. Durch die Schwindung des Kunststoffes erhalten die Dreh- knöpfe und Kegelräder eine mit einem gewissen, durch die Wahl des Kunst- stoffes und die Formgebung bedingten Reibungemoment behaftete Drehbe- weglichkeit und werden dann durch Abwinkeln der Seitenwand (1b) mitein- ander in Eingriff gebracht. The knobs (2) and the bevel gears (3) are according to another proposal of the angled support rail is not injected, WO (4) be injected through the same in the bevel gears in the threaded spindles. Due to the shrinkage of the plastic, the rotary knobs and bevel gears receive a movability afflicted with a certain, due to the choice of plastic and the forming Reibungemoment Drehbe- and brought then by bending the side wall (1b) with one another in engagement.
`Die Gewindespindeln werden am anderen Ende in dem Kunststoffrahmen (6) gelagert, der seinerseits an der Trägerschiene (1) befestigt ist. An der offenen Seite des Rahmens ist die Trägerplatte (7) eingeschoben uns auf Zapfen der Trägerschiene aufgesteckt, die zur Befestigung der Plat t: verschränkt werden. `The threaded spindles are stored at the other end in the plastic frame (6), which in turn is attached to the support rail (1). On the open side of the frame, the carrier plate (7) is pushed in and slipped onto the pins of the carrier rail, which are interlaced to fasten the plate.
Auf der Trägerplatte (7) sind die homogenen Widerstandsschichten (8) aufgetragen, deren Anfänge und Enden durch die Leitsilberschienen (9,1G.. miteinander verbunden sind und deren Breite entlang der Schleiferbahn zur Erzielung einer nichtlinearen Spannungsteilerkurve kontinuierlich abnimmt. The homogeneous resistance layers (8) are applied to the carrier plate (7), the beginnings and ends of which are connected to one another by the conductive silver bars (9,1G ..) and whose width decreases continuously along the wiper track to achieve a non-linear voltage divider curve.
In die Sohleiferträger (5) sind die aus Federdraht geformten Schleifer- federn (12) so eingesetzt, daB sie mit den Gewindespindeln (4) Kontakt haben und mit ihren freien Enden beim Drehen der Spindel auf der strich- punktierten Bahn der Widerstandsschichten (8) mit entsprechendes Kon- taktdruck entlang gleiten. The wiper springs (12) formed from spring wire are inserted into the sole carrier (5) in such a way that they are in contact with the threaded spindles (4) and with their free ends on the dash-dotted path of the resistance layers (8) when the spindle is rotated. slide along with the appropriate contact pressure.
An den Schleiferträgern sind die Vorsprünge (5a) angespritzt, welche in die Schlitze (6a) des Rahmens hineinragen und die jeweilige Stellung des Schleifers anzeigen. The projections (5a), which protrude into the slots (6a) of the frame and indicate the respective position of the grinder, are injection molded onto the wiper supports.
In den hohlen Drehknöpfen (2) sind die Drucktasten (13) axial verschieb- bar angebracht, die eine innere Äusnehmung (13a) besitzen, in welcher die zur Rückstellung dienende Schraubenfeder (14) eingesetzt ist. Die Schraubenfedern stützen sich an der aus Draht geformten Sammelschiene (15) ab, welche in-den Querschlitzen (13b) der Tasten eingelegt ist und an den Stegen (7a) der Widerstandsplatte anliegt. In den Tasten sind die mit Anlaufschrägen versehenen Vorsprünge (13c)angespritzt, welche mit den an der vorderen Seitenwand (1c) längsverachietlich gelagerten und durch die Schraubenfeder (16) vorgespannten Rast- schieber (17) in der Weise zusammenwirken, daB die Taste nach dem Ein- drücken in der Arbeitsstellung einrastet und beim Drücken einer anderen Taste freigegeben und durch die Feder (14) in die Ruhesteltun.-. zurück- gebracht wird. In the hollow rotary knobs (2), the pushbuttons (13) are axially displaceable and have an inner recess (13a) in which the helical spring (14) used for resetting is inserted. The coil springs are supported on the busbar (15) made of wire, which is inserted into the transverse slots (13b) of the keys and rests against the webs (7a) of the resistance plate. The projections (13c) provided with run-up bevels are injection-molded into the keys, which cooperate with the locking slides (17), which are mounted longitudinally on the front side wall (1c) and are pretensioned by the helical spring (16) , in such a way that the key after the mono- press in the operating position locks into place and released by pressing another key, and by the spring (14) in the Ruhesteltun.-. is brought back.
Im Hohlraum (13a) und im Schlitz (13d) der Tasten ist die aus Federdraht geformte Kontaktfeder (18) so eingelegt, daß sie mit dem Teil (18a)hinter der Schraubenfeder (14) einrastet und mit dem langen Schenkel (18b) an der Sammelschiene (15) mit Vorapannung anliegt. Wenn die Taste ge-drückt wird. schiebt sich die Kontaktnase (18c) der Kontaktfeder auf die Stirnseite (4a) der Gewindespindel (Fig.5), wodurch die Sohleiferfeder (12) des zugehörigen Widerstandes (8) mit der Sammelschiene (15) ver- bunden wird. The contact spring (18) made of spring wire is inserted in the cavity (13a) and in the slot (13d) of the keys so that it engages with the part (18a) behind the helical spring (14) and with the long leg (18b) on the Busbar (15) is applied with pre-tensioning. When the button is pressed. the contact nose (18c) of the contact spring pushes onto the end face (4a) of the threaded spindle (Fig. 5), whereby the solenoid spring (12) of the associated resistor (8) is connected to the busbar (15) .
Mit diesem Einstellaggregat können drei Stationsfrequenzen gespeichert werden. Hierzu wird zunächst die erste Taste gedrückt und der zugehörige Drehknopf solange gedreht, bis der Schleifer die für die Frequenz der gewünschten Station erforderliche Spannung der Sammelsohiene (15), wel- che mit der Kapazitätsdiode verbunden ist, zuleitet. Nach dieser erst- maligen Einstellung bleibt die Station gespeichert und kann durch Drücken der ersten Taste jederzeit wieder eingeschaltet werden. In gleicher Wei- se können die zweite und die dritte Taste mit jeder gewünschten Station belegt werden. Die vierte Taste, dient bei den vorliegenden Beispiel zur Umschaltung auf eine kontinuierliche ibstimung. Die gewindespindel ist daher durch den Kontakt (11) ersetzt, welcher beim Drücken der vierten Taste die Sammelsohiene (15) mit den Schleifer eines nicht dargestellten lbstimmwideratandes superhalb des Abatimmaggregatee verbindet. With this setting unit, three station frequencies can be saved. To do this, first press the first button and turn the associated rotary knob until the grinder supplies the voltage required for the frequency of the desired station to the collecting rail (15), which is connected to the capacitance diode. After this initial setting, the station remains saved and can be switched on again at any time by pressing the first button. In the same WEI se the second and third button can be assigned to any desired station. In the present example, the fourth key is used to switch to continuous stimulation. The threaded spindle is therefore replaced by the contact (11) which, when the fourth button is pressed, connects the collecting bar (15) to the slider of a self- tuning resistor (not shown ) above the Abatimmaggregatee .
