Description

Die vorliegende Erfindung betrifft einen Radiusbetätiger für Sicherheitsschalter, bestehend aus einem Halter und einem gegen Federkraft zwischen einer schrägen Anfahrstellung und einer Schalterbetätigungsstellung bewegbar darin gehaltenen Betätigungsbügel, wobei der Betätigungsbügel an seinem innerhalb des Halters liegenden Ende eine Kugel trägt.The present invention relates to a radius actuator for safety switches, consisting of a holder and one against spring force between one inclined approach position and a switch actuation position movable therein held operating bracket, the operating bracket on its inside of the holder lying end carries a ball.

Sicherheitsschalter dienen ganz allgemein der zwangsweisen Abschaltung der Stromzufuhr, wenn beispielsweise eine Schutzabdeckung von einem Gerät oder von einer Maschine entfernt wird, Gehäusetüren, Raumtüren oder dergleichen geöffnet werden.Safety switches are used in general to switch off the Power supply when, for example, a protective cover from a device or is removed from a machine, cabinet doors, room doors or the like be opened.

Derartige Sicherheitsschalter haben üblicherweise mehrere, in unterschiedliche Richtungen orientierte Anfahröffnungen, durch die zwecks Schaltung ein Betätigungsbügel treten kann, der sich beispielsweise zusammen mit einer Tür, einer Klappe oder dergleichen bewegt. Der Radiusbetätiger ist dabei an der Klappe, Tür, Deckel oder dergleichen in einem vorgegebenen Stand von der Klappe oder Drehachse dieses Teiles befestigt. Such safety switches usually have several, in different Direction-oriented approach openings, through the actuation bracket for the purpose of switching can kick, for example, together with a door, one Flap or the like moves. The radius actuator is on the flap, Door, cover or the like in a predetermined position from the flap or Axis of rotation of this part attached.

Derartige Radiusbetätiger werden dann eingesetzt, wenn insoweit in Bezug auf den Sicherheitsschalter der Betätiger an der Tür, Klappe oder Deckel nur auf einem kleinen Schwenkradius angeordnet werden kann. Die Ausgestaltung ist dabei so zu treffen, daß der Radiusbetätiger in der Anfahrphase zum Sicherheitsschalter eine Schräglage (Anfahrstellung) innehat, so daß er bei kleinem Schwenkradius problemlos in den Sicherheitsschalter bzw. dessen Anfahröffnung eintreten kann, er aber im weiteren Verlauf der Schalterbetätigung für die Betätigung beispielsweise eines Schaltrades eines derartigen Sicherheitsschalters eine im wesentlichen zum zu betätigenden Element senkrechte Schalterbetätigungsstellung einnehmen kann. Die Federkraft sorgt dabei dafür, daß der Betätigungsbügel des Radiusbetätigers nach Verlassen des Sicherheitsschalters wieder die Anfahrstellung einnimmt.Radius actuators of this type are used if insofar as the safety switch of the actuators on the door, flap or cover only open a small swivel radius can be arranged. The design is to make so that the radius actuator in the start-up phase to Safety switch is in an inclined position (approach position) so that it is at small swivel radius easily into the safety switch or its Approach opening can occur, but it continues in the course of Switch actuation for the actuation of, for example, a ratchet wheel Such a safety switch essentially to be operated Element can assume vertical switch actuation position. The spring force ensures that the actuating bracket of the radius actuator after Leaving the safety switch returns to the approach position.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Radiusbetätiger der gattungsgemäßen Art zu schaffen, der insgesamt aus verhältnismäßig wenigen Einzelteilen besteht und dessen Betätigungsbügel bezüglich seiner Grundstellung relativ zum Halter leicht einstellbar und fixierbar ist.The present invention has for its object a radius actuator to create the generic type, the total of proportionately there are few individual parts and its operating bracket with respect to its Basic position relative to the holder is easily adjustable and fixable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Betätigungsbügel einen in den Halter ragenden und an seinem dortigen Ende die Kugel tragenden Schaft aufweist, daß die Kugel in einem aus zwei durch Schrauben miteinander verbundenen Hälften bestehenden, rohrschellenartigen Klemmteil fest eingespannt ist, welches in einer Hohlkammer des Halters liegt und an seiner dem Betätiger abgewandten Stirnfläche von einer andererseits am Halter abgestützten Feder beaufschlagt ist und daß der Halter mit zwei in die Hohlkammer mündenden und mit den Schrauben des Klemmteiles fluchtenden Montagebohrungen versehen ist.This object is achieved in that the operating bracket one protruding into the holder and carrying the ball at its end there Shank has the ball in one of two by screwing each other connected halves existing, clamp-like clamp part is clamped, which lies in a hollow chamber of the holder and on it the face facing away from the actuator on the other hand on the holder supported spring is loaded and that the holder with two in the Opening the hollow chamber and aligning with the screws of the clamping part Mounting holes is provided.

Der Radiusbetätiger gemäß vorliegender Erfindung besteht aus einer äußerst geringen Anzahl von Einzelteilen und wird dennoch allen eingangs geschilderten Anforderungen an einen derartigen Radiusbetätiger gerecht.The radius actuator according to the present invention consists of an extreme small number of individual parts and is still all described above Requirements for such a radius actuator.

Es wird lediglich der Halter, der Betätigungsbügel selbst mit dem daran angeformten und die Kugel aufweisenden Schaft sowie das Klemmteil und eine Feder benötigt, um den erfindungsgemäßen Radiusbetätiger zu realisieren.It is only the holder, the operating bracket itself with it molded and the ball shaft, the clamping part and a Spring needed to implement the radius actuator according to the invention.

Die Grundeinstellung des Betätigungsbügels wird nach einem leichten Lösen der die Hälften des Klemmteiles miteinander verbindenden Schrauben vorgenommen, was durch die in die Hohlkammer des Halters führenden Montagebohrungen bei an sich komplett montierten Radiusbetätiger möglich ist. Nachdem die gewünschte Grundeinstellung gefunden ist, werden die beiden Schrauben fest angezogen, so daß nunmehr der Betätigungsbügel mit seinem Schaft, der an dem Ende des Schaftes vorgesehenen Kugel und dem Klemmteil eine Baueinheit bildet, die in gewissen Grenzen gegenüber der Schaft-Längsachse verschwenkt werden kann.The basic setting of the operating bracket is after a slight loosening of the screws connecting the halves of the clamping part made what by leading into the hollow chamber of the holder Mounting bores is possible with a completely assembled radius actuator. After the desired basic setting is found, the two Screws tightened so that the operating bracket with his Shaft, the ball provided at the end of the shaft and the clamping part forms a structural unit within certain limits with respect to the longitudinal axis of the shaft can be pivoted.

Eine besonders vorteilhafte Ausführungsform des Radiusbetätigers besteht darin, daß der Halter im Durchtrittsbereich des Schaftes mit zwei sich kreuzenden Führungsschlitzen für den Schaft des Betätigungsbügels versehen ist.A particularly advantageous embodiment of the radius actuator exists in that the holder in the passage area of the shaft with two intersecting guide slots for the shaft of the operating bracket is.

Durch diese beiden Führungsschlitze wird ein exaktes Voreinstellen der Grundposition des Betätigungsbügels wesentlich erleichtert, ohne daß diese konstruktive Ausgestaltung des Halters zu nennenswerten Mehrkosten führt.These two guide slots ensure that the Basic position of the actuating bracket significantly facilitated without this constructive design of the holder leads to significant additional costs.
