Abstract
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 a spring force between a oblique starting position and a switch operating position movable therein held operating bracket, wherein the operating bracket at its inside 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 generally used for the forced shutdown of Power supply, for example, when a protective cover of 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 Directions oriented approach openings, by the purpose of switching an operating handle can occur, for example, together with a door, a Flap or the like moves. The radius actuator is at the flap, Door, cover or the like in a predetermined state of the flap or Fastened axis of rotation of this part.
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.Such radius actuators are then used, if so far in relation to the safety switch of the actuator on the door, flap or lid only on a small swivel radius can be arranged. The design is to make it so that the radius actuator in the starting phase for Safety switch has a sloping position (starting position), so that he at Small swivel radius easily in the safety switch or its Anfahröffnung may occur, but he in the further course of Switch operation for the operation of a ratchet wheel, for example Such safety switch a substantially to be operated Element vertical switch actuation position can take. The spring force ensures that the actuating bow of the radius actuator after Leaving the safety switch again assumes the starting position.
Im Dokument "DE 297 01 797 U" wird ein Radiusbetätiger,
gemäß dem Oberbegriff des Patentanspruchs 1 offenbart.The document "DE 297 01 797 U" describes a radius actuator,
disclosed according to the preamble of
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 is based on the object, a radius actuator of the generic type to create the total of relatively consists of few items and whose operating handle with respect to his Basic position relative to the holder 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 actuating bracket a protruding into the holder and at its local end bearing the ball Shank has that the ball in one of two by screws with each other connected halves existing, clamp-like clamping part firmly is clamped, which lies in a hollow chamber of the holder and on his the actuator facing away from an end on the other hand on the holder supported spring is applied and that the holder with two in the Hollow opening and aligned 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 extremely small number of items and is still all initially described Requirements for such a radius actuator fair.
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 handle itself with the molded and the ball having shaft and the clamping part and a Spring required to realize 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 actuating yoke is after a slight release of the the halves of the clamping part interconnecting screws made, which by leading into the hollow chamber of the holder Mounting holes in completely assembled radius actuator is possible. After the desired basic setting is found, the two become Tightened screws so that now the operating handle with his Shank, which provided at the end of the shaft ball and the clamping part forms a structural unit, which within certain limits with respect to the shaft longitudinal axis 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 region of the shaft with two itself provided crossing guide slots for the shaft of the actuating 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.Through these two guide slots is an exact presetting the Basic position of the actuating bracket much easier without this constructive design of the holder leads to significant additional costs.
Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the accompanying drawings and will be described in more detail below.
