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.The present invention relates to a radius actuator for safety switches from a holder and one against spring force between an oblique approach position and a switch operating position movable operating bracket held therein.
Sicherheitsschalter werden zur zwangsweisen Abschaltung der Stromzufuhr beispielsweise an Maschinen mit einer Schutzabdeckung bei Gehäusetüren, Raumtüren oder dergleichen eingesetzt. Sicherheitsschalter dieser Art besitzen üblicherweise mehrere, in unterschiedlichen Richtungen orientierte Anfahröffnungen, durch die zum Zwecke der Schaltung ein Betätiger treten kann, der sich beispielsweise zusammen mit einer Tür, einer Klappe oder dergleichen bewegt.Safety switches are used, for example, to switch off the power supply on machines with a protective cover for enclosure doors, room doors or the like used. Safety switches of this type usually have several approach openings oriented in different directions, through which to For the purpose of switching an actuator can step, for example, together moved with a door, a flap or the like.
Der Radiusbetätiger ist dabei an der Klappe, Tür, Deckel oder dergleichen in einem vorgegebenen Abstand von der Klapp- oder Drehachse dieses Teiles befestigt.The radius actuator is on the flap, door, lid or the like in one predetermined distance from the folding or rotating axis of this part attached.
Radiusbetätiger der gattungsgemäßen Art werden dann eingesetzt, wenn in Bezug auf den Sicherheitsschalter der Betätiger an der Tür, Klappe oder Deckel nur auf einem kleinen Schwenkradius angeordnet werden kann. Dabei ist dafür Sorge zu tragen, 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. Durch die Federkraft ist dabei sichergestellt, daß der Betätigungsbügel des Radiusbetätigers nach Verlassen des Sicherheitsschalters wieder die Anfahrstellung einnimmt.Radius actuators of the generic type are used when in relation on the safety switch of the actuators on the door, flap or cover only on one small swivel radius can be arranged. Care must be taken that the radius actuator in the start-up phase to the safety switch Tilted position (approach position), so that it easily with a small swivel radius can enter the safety switch or its approach opening, but he in further course of the switch actuation for the actuation, for example, of one Switching wheel of such a safety switch one to be operated essentially Element can assume vertical switch actuation position. By the spring force ensures that the actuating bracket of the radius actuator returns to the approach position after leaving the safety switch.
Bei bekannten Radiusbetätigern der gattungsgemäßen Art ist bislang nur die Möglichkeit gegeben, den Betätigungsbügel durch Schwenken um eine Achse in eine schräge Anfahrstellung voreinzustellen.In known radius actuators of the generic type, only the possibility is so far given the actuating bracket by swiveling around an axis in a Preset inclined approach position.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Radiusbetätiger der gattungsgemäßen Art mit einfachen Mitteln dahingehend zu verbessern, daß dessen Betätigungsbügel entsprechend allen denkbaren Einsatzfällen in eine schräge Anfahrstellung voreingestellt werden kann.The present invention has for its object a radius actuator Generic type with simple means to improve that Operating bracket according to all conceivable applications in an inclined starting position can be preset.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Betätigungsbügel an einem Ende eines Tragteiles befestigt ist, dessen anderes Ende in den Halter hineinragt, daß der Betätigungsbügel gegenüber dem Tragteil um eine Schwenkachse verschwenkbar und in jeder möglichen Verschwenkstellung relativ zum Tragteil festlegbar ist, daß das Tragteil mit seinem in den Halter hineinragenden Ende an einer Grundplatte befestigt und gegenüber dieser Grundplatte um eine zweite Schwenkachse verschwenkbar sowie in jeder möglichen Verschwenkstellung relativ zur Grundplatte festlegbar ist, wobei die zweite Schwenkachse gegenüber der Schwenkachse vom Tragteil und Betätigungsbügel um 90 Grad versetzt verläuft und daß die Grundplatte innerhalb des Halters entgegen der Wirkung einer im Halter angestützten Feder in Richtung der Längsachse des Tragteiles verschiebbar sowie in Grenzen gegenüber diese Längsachse kippbar ist.This object is achieved in that the actuating bracket one end of a support part is attached, the other end of which projects into the holder, that the actuating bracket is pivotable relative to the support member about a pivot axis and can be fixed in any possible pivot position relative to the supporting part is that the support member with its end protruding into the holder at one Base plate attached and opposite this base plate by a second Swivel axis pivotable and relative in any possible pivot position can be fixed to the base plate, the second pivot axis being opposite the The swivel axis is offset by 90 degrees from the supporting part and operating bracket and that the base plate is supported within the holder against the action of one in the holder Spring displaceable in the direction of the longitudinal axis of the support part and in Limits relative to this longitudinal axis can be tilted.
Ein derart gestalteter Radiusbetätiger kann entsprechend jedem denkbaren Einsatzzweck derart voreingestellt werden, daß sein Betätigungsbügel die jeweils gewünschte bzw. erforderliche schräge Anfahrstellung aufweist.Such a radius actuator can be used for any conceivable purpose be preset so that its operating bracket the desired one or has the required inclined approach position.
Durch lediglich eine Feder innerhalb des Halters wird die Möglichkeit geschaffen, das Tragteil beim Einfahren des Betätigungsbügels in einen Sicherheitsschalter bzw. dessen Anfahröffnung um den hierfür notwendigen Betrag zu kippen, umgekehrt wird das Tragteil mit dem daran befestigten Betätigungsbügel durch die Feder wieder in seine Grundstellung zurückbewegt, wenn der Radiusbetätiger vollständig vom Sicherheitsschalter getrennt ist.Just one spring inside the holder creates the possibility that Supporting part when retracting the operating bracket into a safety switch or whose approach opening is tilted by the amount necessary for this, is reversed the supporting part with the actuating bracket attached to it by the spring moves back to its basic position when the radius actuator is completely off the safety switch is separated.
Aufgrund der Tatsache, daß das Tragteil letztendlich in seiner Achsrichtung federbelastet ist, wird der zusätzliche Vorteil erreicht, daß bei ungewolltem Anstoßen an den Betätigungsbügel die hierbei auftretenden Belastungen abgefedert und somit die Beschädigungsgefahr verringert wird.Due to the fact that the supporting part is ultimately spring-loaded in its axial direction is the additional advantage is achieved that in the event of unintentional bumping into the Operating bracket cushioned the loads that occur and thus the risk of damage is reduced.

im wesentlichen aus einem gehäuseartigen Halter 1 sowie aus einem gegen Federkraft
zwischen einer schrägen Anfahrstellung und einer Schalterbetätigungsstellung
bewegbar darin gelagerten Betätigungsbügel 2, wobei der Betätigungsbügel 2 an einem
Tragteil 3 befestigt ist, dessen anderes Ende in den Halter 1 hineinragt.The radius actuator for safety switches shown in the drawings exists
essentially from a housing-

4 ausgebildet, wobei dieser Gabelkopf 4 einen Aufnahmeschlitz 5 für den
Betätigungsbügel 2 aufweist. The
Quer zu diesem Schlitz 5 läuft eine Bohrung 6, der eine entsprechende Durchgangsbohrung
7 im Betätigungsbügel 2 zugeordnet ist. Durch die Bohrung 6 und die Aufnahmebohrung
7 ist ein Zapfen 8 hindurchgeführt, um den der Betätigungsbügel 2
relativ zum Tragteil 3 verschwenkbar ist.A bore 6 runs across this slot 5 and has a corresponding through bore
7 is assigned in the
In einem Abstand zum Zapfen 8 ist durch den Gabelkopf 4 eine Klemmschraube 9
hindurchgeführt, die den Betätigungsbügel 2 im Bereich eines kreisbogenförmigen
Langloches 10 durchtritt.At a distance from the
Durch die Klemmschraube 9 kann der Gabelkopf 4 lotrecht zum Schlitz 5 zusammengeklemmt
und damit der Betätigungsbügel 2 im Gabelkopf 4 eingeklemmt und
festgesetzt werden. Durch das kreisbogenförmige Langloch 10 kann der Betätigungsbügel
2 um den eine Schwenkachse bildenden Zapfen 8 in Grenzen relativ zur
Längsachse des Tragteiles 3 verschwenkt und in jeder möglichen Verschwenkstellung
relativ zum Tragteil festgelegt werden.By means of the clamping screw 9 the fork head 4 can be clamped perpendicular to the slot 5
and thus the actuating
Das in den gehäuseartigen Halter 1 hineinragende Ende des Tragteiles 3 ist an einer
Grundplatte 11 festgelegt und kann gegenüber dieser Grundplatte 11 um eine zweite
Schwenkachse 12 verschwenkt sowie in jeder möglichen Verschwenkstellung relativ
zur Grundplatte 11 festgelegt werden.The end of the
Die Schwenkachse 12 entspricht der Längsachse einer Schraube 13, die die Grundplatte
11 sowie eine Bohrung 14 des Tragteiles 3 durchtritt. Die Grundplatte 11 weist
eine zentrale Aussparung 15 auf, in die das halterseitige und mit der Bohrung 14 versehene
Ende des Tragteiles 3 hineinragt. Innerhalb dieser Aussparung 15 kann das
halterseitige Ende des Tragteiles 3 in jeder möglichen Verschwenkstellung festgeklemmt
werden.The
Die zweite Schwenkachse 12 verläuft um 90 Grad versetzt zu der Schwenkachse
zwischen Tragteil 3 einerseits und Betätigungsbügel 2 andererseits.The
Die Grundplatte 11 ist innerhalb des Halters 1 in Richtung der Längsachse des
Tragteiles 3 durch eine Feder 16 beaufschlagt. Weiterhin ist die Grundplatte 11 innerhalb
des Halters 1 in einer dem quadratischen Grundriß der Grundplatte 1 entsprechend
gestalteten Ausnehmung 17 axial verschiebbar, aber nicht drehbar geführt.The
Die Grundplatte 11 ist so dimensioniert, daß die Möglichkeit besteht, die Grundplatte
11 innerhalb dieser Ausnehmung 17 gegenüber der Längsachse des Tragteiles 3 zu
kippen. The
Die Feder 16 stützt sich einerseits an der Grundplatte 11 und andererseits an einer
den Halter 1 verschließenden Scheibe 18 ab.The
Aus der vorstehend beschriebenen Konstruktion ergeben sich hinsichtlich des Einsatzes des Radiusbetätigers nun folgende Möglichkeiten:The construction described above results in the use of the radius actuator now have the following options:
Das Tragteil 3 kann lotrecht zur Grundplatte 11 an dieser befesteigt sein. In diesem
Falle wird der Betätigungsbügel 2 in einer relativen Verschwenkstellung zum Tragteil
3 an diesem befestigt, so wie dies in Figur 6 gezeigt ist.The supporting
Ebenso ist es denkbar, den Betätigungsbügel 2 in einer Flucht mit der Längsachse
des Tragteiles 3 an diesem festzulegen. In diesem Falle wird das Tragteil 3 gegenüber
der Grundplatte 11 in einer beliebigen Richtung verschwenkt und in dieser Verschwenkstellung
mit der Grundplatte 11 fest verbunden. Diese Möglichkeit ist in den
Figuren 3 und 4 gezeigt.It is also conceivable to align the actuating
Die Figuren 4 und 6 zeigen jeweils die sogenannte Anfahrstellung, d. h. diejenige Position,
in der sich der gesamte Radiusbetätiger außerhalb eines Sicherheitsschalters
befindet. Entsprechend der jeweiligen Schrägstellung des Betätigungsbügels 2 kann
dieser in einen Sicherheitsschalter eingefahren werden und wird dann letztendlich
aus der in den Zeichnungen dargestellten Anfahrstellung in eine Schalterbetätigungsstellung
bewegt, wobei eine Schalterbetätigungsstellung in Figur 3 dargestellt
ist. Hier ist deutlich zu erkennen, daß dabei die Grundplatte 11 innerhalb des Halters
1 gekippt ist, wobei durch die Feder 16 beim Trennen des Radiusbetätigers von einem
Sicherheitsschalter wieder die aus Figur 4 ersichtliche Anfahrstellung herbeigeführt
wird dadurch, daß diese Feder 16 die Grundplatte 11 wieder in ihre Grundstellung
zurückbewegt.Figures 4 and 6 each show the so-called approach position, i. H. the position
in which the entire radius actuator is outside of a safety switch
located. According to the respective inclination of the
Auch bei einer Einsatzsituation, wie sie sich aus einer Voreinstellung des Betätigungsbügels
2 gemäß der Ausführungsform nach Figur 6 ergibt, wird das Tragteil 3
in der Schalterbetätigungsstellung gegenüber seiner Längsachse gekippt, was aufgrund
der durch die Feder 16 belasteten Grundplatte 11 ohne weiteres möglich ist.
Nach dem Trennen von Radiusbetätiger und Sicherheitsschalter wird dann wieder die
aus Figur 6 ersichtliche Grundstellung herbeigeführt.Even in an application situation as it results from a presetting of the
Da die Grundplatte 11 innerhalb der Ausnehmung 17 entgegen der Wirkung der Feder
16 beweglich ist, können auch unbeabsichtigte Stöße auf den Betätigungsbügel 2
entsprechend federnd abgefangen werden, so daß die Zerstörungsgefahr des Radiusbetätigers
vergleichsweise gering ist.Since the
