Die Erfindung betrifft eine Vorrichtung zum Abheben oder Absenken eines von einem Hebearm
gehaltenen, höhenveränderlich gelagerten Tonkopfes
auf eine auf einem Plattenteller liegende Schallplatte.
Bei Phonogeräten, insbesondere bei Plattenwechslern, 5
muß der von einem Hebearm gehaltene Tonkopf
bekanntlich angehoben und gesenkt werden. Zu
diesem Zweck ist beispielsweise eine Ausführung
bekannt, bei welcher der Tonarm mittels eines von
Hand betätigbaren Hebels gehoben und gesenkt io
wird. Andere Geräte bedienen sich zur Höhenänderung des Tonkopfes einer selbsttätig wirkenden 2
Hebeeinrichtung, die von einer Kurvenscheibe herThe invention relates to a device for raising or lowering one of a lifting arm
held, height-adjustable mounted clay head
on a record lying on a turntable.
For phono devices, especially record changers, 5
must be the tape head held by a lifting arm
is known to be raised and lowered. to
this is an example of an implementation
known, in which the tonearm by means of one of
Hand operated lever raised and lowered io
will. Other devices use an automatically acting 2 to change the height of the sound head

gesteuert wird. Für viele Zwecke ist es nun aber Achse 4 ist in einer sie umgebenden Hohlachse 5 erwünscht, das Anheben und Absenken des Ton- 15 höhenbeweglich geführt. Auch die Hohlachse, die an kopfes wahlweise sowohl mittels handgesteuerten zwei in der Zeichnung nicht vermerkten Stellen geHebels als auch selbsttätig mittels einer Kurven- lagert ist, kann sich axial bewegen. In Höhe einer mit scheibe, unabhängig voneinander, vornehmen zu einem profilierten Rand versehenen Steuerscheibe 7 können. ist die Hohlachse 5 mit einem quer zu ihm verlaufen-is controlled. For many purposes, however, it is now axis 4 in a hollow axis 5 that surrounds it desired, the raising and lowering of the pitch 15 guided vertically. Also the hollow axle that is attached to head either by means of hand-controlled two positions not noted in the drawing as well as automatically by means of a cam, can move axially. Equal to one with disc, independently of one another, make a control disc 7 provided with a profiled edge can. is the hollow axle 5 with a transverse to it
Gemäß der Erfindung wird dies dadurch erreicht, 20 den Stift 6 versehen, der mit seinem einen Ende daß die vertikale Achse des Hebeannes in einer sie gegen den Rand der Steuerscheibe 7 anliegt und teleskopartig umgebenden mit öl gefüllten Dämp- dessen anderes Ende in einer vertikalen Schlitzfungsbüchse geführt ist, die über eine Zugfeder mit führung 8 liegt. Eine im Innern der Hohlachse 5 dem Hebearm verspannt ist und in die ein mit seinem befindliche Ölmenge dient bei den axialen Beeinen Ende unter den profilierten Rand einer Steuer- 35 wegungen der Achse 4 gegenüber der Hohlachse 5 scheibe anliegender Stift fest angeordnet ist, dessen als Dämpfungspolster. Der Hebearm 11 ist mit dem entgegengesetztes Ende unter der Wirkung einer unteren Ende der Hohlachse 5 über eine Zugfeder 10 weiteren Feder einer nach oben hin gerichteten Zug- verbunden, die bewirkt, daß die Achse 4 mit dem spannung unterliegt, und weiter dadurch, daß im Hebearm 11 ständig nach unten in die Richtung b Bereich eines vom Tonkopf abstehenden Auslegers 30 gezogen wird. Die Feder 10 hat die Aufgabe, den eine gegebenenfalls als federndes Glied oder als kompletten Hebearm 11 mit seiner Achse 4 sicher in Blattfeder ausgebildete Hebeschräge angeordnet ist, die Hohlachse 5 gegen die Kraft der Dämpfung zu die an einer von Hand in Längsrichtung verschieb- ziehen, so daß beide Teile kraftschlüssig miteinander baren Steuerstange abstehend befestigt ist. Eine verbunden sind. (Kraft der Feder 10 etwa 20 p.) weitere Vervollkommnung dieser Lösung ergibt sich, 35 Andererseits wird durch eine am Stift 6 angreifende wenn die genannte Steuerstange über eine winklig zu weitere Feder 9 die Hohlachse S mit dem Stift 6 ihr stehende Schenkelfeder mit einem von Hand in ständig in Richtung α nach oben gezogen. Ein Ende Längsrichtung der Steuerstange verstellbaren Schieber dieser Feder ist am Stift befestigt, das andere am verbunden ist. Chassis. Die Feder 9 hat die Aufgabe, die komplette, In zwei Ausführungsbeispielen ist die Erfindung 40 zusammengefahrene Einheit 11-4-5 nach oben zuAccording to the invention, this is achieved by providing the pin 6 with its one end that the vertical axis of the lifting arm rests against the edge of the control disk 7 and telescopically surrounding it with oil-filled dampers, the other end of which is in a vertical slot bushing is guided, which is via a tension spring with guide 8. One inside the hollow axle 5 is braced on the lifting arm and in which an amount of oil located is used at the axial legs end under the profiled edge of a control movements of the axle 4 opposite the hollow axle 5 disk adjacent pin is firmly arranged, its as a damping pad . The lifting arm 11 is connected to the opposite end under the action of a lower end of the hollow axle 5 via a tension spring 10 further spring of an upwardly directed tension, which causes the axle 4 to be subject to tension, and further by the fact that in Lifting arm 11 is constantly pulled down in the direction b area of an arm 30 protruding from the sound head. The spring 10 has the task of arranging a lifting bevel, possibly designed as a resilient member or as a complete lifting arm 11 with its axis 4 safely in leaf spring, to pull the hollow axis 5 against the force of the damping to the one by hand in the longitudinal direction, so that both parts are non-positively attached to each other ble control rod protruding. One are connected. (Force of the spring 10 about 20 p.) Further perfection of this solution results, 35 On the other hand, when the said control rod engages the pin 6 via an angled to further spring 9, the hollow axis S with the pin 6 standing up to it with a leg spring with one of Hand is constantly pulled up in the direction of α. One end of the longitudinal direction of the control rod adjustable slide of this spring is attached to the pin, the other is connected to the. Chassis. The spring 9 has the task of the complete, In two embodiments, the invention 40 is moved together unit 11-4-5 to the top
