Abstract

The control key converts a pivoting movement of the handle (5) into a straight-lined movement of the pressure piece (3) by means of a curve and a cam (10) which interacts therewith. The hollow-cylindrical pressure piece (3) has two curves (11, 13) on the radius, one curve (11) of which has a latching depression. When the cam (10) interacts with this curve (11), the control key latches in the limit position. After twisting the pressure piece (3) through 180 DEG , the second curve (13) interacts with the cam (10). This curve has no latching depression. The handle (5) pivots back into the original position after being operated, because of the spring force of the compression spring (4). <IMAGE>

Description

Befehlstaste mit DrehantriebCommand button with rotary drive

Die Erfindung bezieht sich auf eine Befehlstaste mit Drehantrieb gemäß dem Oberbegriff des Anspruchs 1. Befehlstasten der obengenannten Art sind bereits in verschiedenen Ausführungen bekannt. Die DE-PS 14 40 615 zeigt einen Drehantrieb zur Betätigung von Tastschaltern, bei der in Fig. 2 die Abwicklung der Kurve zu sehen, die mit dem Antriebsteil zusammenwirkt.The invention relates to a command key with rotary drive according to the preamble of claim 1. Command buttons of the type mentioned above are already known in various designs. DE-PS 14 40 615 shows a rotary drive for the actuation of pushbutton switches, in which in Fig. 2 the development of the curve to see, which cooperates with the drive part.

Am unteren Teil der Kurve 11 ist die Vertiefung sichtbar, die zur Verrastung des Drehantriebes in der Endstellung dient.At the lower part of curve 11, the indentation is visible, which leads to The rotary drive is locked in the end position.

Will man erreichen, daß sich der Drehantrieb nach der Betätigung wieder in die Ursprungsstellung zurückbewegt, verzichtet man auf die Vertiefung am Ende der Kurve. Zur Erreichung der beiden genannten Funktionen sind unterschiedliche Typen von Drehantrieben erforderlich.If you want to achieve that the rotary drive is again after actuation moved back to the original position, one dispenses with the recess at the end the curve. To achieve the two functions mentioned are different Types of rotary actuators required.

Der Erfindung liegt die Aufgabe zugrunde einen Drehantrieb zu schaffen, der zur Typenreduzierung beide Funktionen in einer Ausführung erfüllen kann.The invention is based on the object of creating a rotary drive, which can fulfill both functions in one design to reduce the type.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Befehlstaste nach Bedarf in einen in der Schwenkstellung verrastenden oder nicht verrastenden und damit in die Ausgangsstellung zurückdrehenden Drehantrieb einstellbar ist.This object is achieved according to the invention in that the command key as required in a locking or non-locking in the pivot position and thus the rotary drive rotating back into the starting position is adjustable.

Diese Einstellbarkeit kann dadurch erreicht werden, daß das hohlzylindrische Druckstück zwei unterschiedlich ausgeführte Kurven ausweist, und daß der Nocken zur Erfüllung der verrastenden Funktion mit der Kurve zusammenwirkt, die an ihrem oberen Ende eine Vertiefung aufweist, in die der Nocken einrastet.This adjustability can be achieved in that the hollow cylindrical Pressure piece identifies two differently executed curves, and that the cam to fulfill the locking function cooperates with the curve that is on her upper end has a recess into which the cam engages.

Nach Einstellung der nicht rastenden Funktion wirkt der Nocken mit der zweiten Kurve zusammen, die keine Rastvertiefung aufweist. Dadurch wird er aufgrund der Federkraft einer Durckfeder wieder in die Ausgangsstellung zurückbewegt, wenn keine Betätigungskraft mehr auf den Knebel wirkt. Die Umstellung der Funktion erfolgt, indem das hohlzylindrische Druckstück gegen die Kraft der Druckfeder, die sich einerseits am Kragen des Druckstückes und andererseits an einer Anlagefläche der Tastenhülse abstützt, so weit aus der Tastenhülse herausgezogen wird, daß die Führungsnasen über den Rand der Tastenhülse ragen. Dadurch läßt sich das Druckstück soweit drehen, daß die Führungsnasen in die jeweils gegenüberliegenden Führungsschlitze einrasten.After the non-latching function has been set, the cam takes effect the second curve together, which has no locking recess. This will make him due the spring force of a compression spring is moved back into the starting position when there is no longer any actuation force acting on the toggle. The function is changed, by the hollow cylindrical pressure piece against the force of the compression spring, which is on the one hand on the collar of the pressure piece and on the other hand on a contact surface of the key sleeve supported, so far pulled out of the key shell will that the Guide lugs protrude over the edge of the key shell. This allows the pressure piece Turn so that the guide lugs are in the opposite guide slots snap into place.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung dargestellt und näher erläutert.An exemplary embodiment according to the invention is illustrated with the aid of the drawing shown and explained in more detail.

Es zeigt: Fig. 1 die Befehistaste in Seitenansicht teilweise geschnitten gemäß der Linie A-A in Fig. 2 Fig. 2 eine Ansicht der Befehlstaste in Richtung B aus Fig. 1 Fig. 3 eine Abwicklung der mit dem Nocken zusammenwirkenden Kurven.It shows: FIG. 1 the command key in a side view, partially in section according to the line A-A in Fig. 2 Fig. 2 is a view of the command key in direction B. from Fig. 1, Fig. 3 a development of the curves interacting with the cam.

Die in Fig. 1 dargestellte Befehistaste mit Drehantrieb ist üblicherweise in einer Montageplatte 30 montiert und mittels eines Gewinderinges 9 unter Verwendung eines Dichtringes 6, verschraubt. Die Schwenkbewegung erfolgt über den Knebel 5, der mit dem den Nocken 10 tragenden Zwischenstück 2 durch die Schraube 19 fest verbunden ist. Das Zwischenstück 2 ist durch den Frontring 8, der mit der Tastenhülse 1 verschraubt ist, drehbar gehalten. Zum Schutz gegen äußere Einflüsse ist noch ein Dichtring 7 vorgesehen. Zwischen der Tastenführung 1 und dem Zwischenstück 2 ist noch ein hier nicht näher dargestellter Anschlag angeordnet, der den Drehwinkel des Drehantriebs begrenzt. Das hohizylindrische Druckstück 3 ist in der Tastenführung 1 axial beweglich geführt. Es wird durch die Druckfeder 4 die sich einerseits an dem Kragen 20 und andererseits an der Anlagen fläche 21 der Tasten führung 1 abstützt gegen das Zwischenstück 2 gedrückt.The command key shown in Fig. 1 with rotary drive is usually mounted in a mounting plate 30 and using a threaded ring 9 a sealing ring 6, screwed. The pivoting movement takes place via the toggle 5, firmly connected to the intermediate piece 2 carrying the cam 10 by the screw 19 is. The intermediate piece 2 is through the front ring 8, which is screwed to the key sleeve 1 is held rotatable. There is also a sealing ring to protect against external influences 7 provided. Between the key guide 1 and the intermediate piece 2 is still a Arranged here, not shown in detail, the stop that the angle of rotation of the rotary drive limited. The hollow cylindrical pressure piece 3 is axially movable in the key guide 1 guided. It is by the compression spring 4 on the one hand on the collar 20 and on the other hand, on the system surface 21 of the key guide 1 is supported against the intermediate piece 2 pressed.

In Fig. 2 sind zwei Führungsnasen 15, 17 des Druckstückes 3 erkennbar. Sie greifen in die Führungsschlitze 16, 18 und sichern das Druckstück 3 gegen Verdrehen. An diesen Führungsnasen 15, 17 läßt sich das Druckstück 3 jedoch in axialer Richtung gegen die Kraft der Druckfeder 4 so weit aus der Tastenführung ziehen, daß die Führungsnasen über den unteren Rand 22 der Tastenführung ragen. Dann läßt sich das Druckstück 3 soweit verdrehen, daß die Führungsnase 15 in die Führungsbahn 18 und die Führungsnase 17 in die Führungsbahn 16 einrastet.In Fig. 2, two guide lugs 15, 17 of the pressure piece 3 can be seen. They engage in the guide slots 16, 18 and secure the pressure piece 3 against rotation. On these guide lugs 15, 17, however, the pressure piece 3 can be moved in the axial direction Against the force of the compression spring 4 pull so far out of the key guide that the guide lugs over the lower Edge 22 of the key guide protrude. Then you can turn the pressure piece 3 so far that the guide nose 15 in the guide track 18 and the guide nose 17 engages in the guide track 16.

Auf dem oberen Rand des hohlzylindrischen Druckstückes 3 befinden sich gegenüberliegend zwei Kurven 11 und 13 deren Abwicklung in Fig. 3 dargestellt ist. In eine dieser Kurven greift der am Zwischenstück 2 angeordnete Nocken 10.Located on the upper edge of the hollow cylindrical pressure piece 3 opposite two curves 11 and 13, the development of which is shown in FIG is. The cam 10 arranged on the intermediate piece 2 engages in one of these curves.

Bei Betätigung des Knebels 5 drückt der Nocken 10 über die Kurvenbahn 11 das Druckstück in axialer Richtung bis der Nocken 10 in der Vertiefung 12 einrastet. Das Druckstück 3 und damit auch der Knebel 5 verbleiben dann in dieser Raststellung bis durch äußere Betätigung die Rückstellung erfolgt.When the toggle 5 is actuated, the cam 10 pushes over the cam track 11 the pressure piece in the axial direction until the cam 10 engages in the recess 12. The pressure piece 3 and thus also the toggle 5 then remain in this locking position until it is reset by external actuation.

Wird das Druckstück 3 in der oben beschriebenen Weise aus der Tastenführung 1 gezogen und um 1800 gedreht, greift der Nocken 10 in die Kurve 13. Bei Betätigung des Knebels 5 wird das Druckstück 3 ebenfalls wie oben beschrieben durch die Kurve 13 in axialer Richtung gegen die Kraft der Druck feder 4 bewegt. Da jedoch am Ende der Kurve die Vertiefung fehlt, wird das Druckstück 3 und damit über die Kurve 13 und den Nocken 10 auch der Knebel 5 wieder in die Ausgangsstellung bewegt.If the pressure piece 3 is removed from the key guide in the manner described above 1 pulled and rotated by 1800, the cam 10 engages in the curve 13. When actuated of the toggle 5 is the pressure piece 3 also as described above through the curve 13 moves in the axial direction against the force of the compression spring 4. But there in the end the curve lacks the recess, the pressure piece 3 and thus over the curve 13 and the cam 10 also moves the toggle 5 back into the starting position.
