Die Erfindung betrifft einen Druckmittelzylinder mit einseitig herausgeführter Kolbenstange mit einem Betestigungselement und mit einen Funktionsblock, wobei der das Zylinderrohr kolbenseitig abschließender Zylinderboden das Befestigungselement und den aufgesetzten Funktionsblock mit Funktionselementen, beispielsweise Anschlüssen, Ventilen, Druckspeichern oder dergleichen, trägt.The invention relates to a pressure cylinder with one side led out piston rod with a Betestigungselement and with a functional block, wherein the the cylinder tube piston side final cylinder bottom the fastener and the attached functional block with functional elements, for example terminals, Valves, accumulators or the like, carries.
Ein solcher Druckmittelzylinder ist aus WO 99 34119 bekannt.Such a pressure cylinder is known from WO 99 34119.
Derartige Zylinder sind für verschiedenste Anwendungen bekannt und erlauben bei einfacher und kompakter Bauweise eine sichere Funktion sowie das Bereitstellen von in weiten Grenzen variierbaren Hüben bzw. Kräften. Besonders für sicherheitstechnische Anwendungen ist es oft erwünscht oder erforderlich, daß zumindest einzelne Funktionselemente der Ansteuerung derartiger Zylinder unmittelbar und ohne Behinderung oder erhöhtes Risiko darstellende Leitungen am Zylinder selbst angeordnet sind. Abgesehen von einer den Gesamtaufbau sowie naturgemäß auch Montage und Wartung kompliziert machenden Anordnung derartiger Funktionselemente einstückig mit dem bzw. im Zylinderboden, -deckel oderrohr, haben sich in diesem Zusammenhang vor allen Dingen Anordnungen bewährt, bei denen blockartig zusammengefaßte Funktionseinheiten auf dem Zylinderboden bzw. im Bereich des Zylinderbodens aufgesetzt sind. Diese Funktionsblöcke sind dazu auf entsprechend zu bearbeitenden Anschlußflächen abgedichtet aufgeschraubt, wobei die erforderlichen Druckmittelverbindungen über zusammenpassende Mündungen der entsprechenden Leitungen an den zusammenwirkenden Anschlußflächen hergestellt werden.Such cylinders are known for a variety of applications and allow at simple and compact design a safe function as well as providing in wide Limits of variable strokes or forces. Especially for safety applications Often it is desirable or required that at least individual functional elements the control of such cylinders directly and without hindrance or increased risk performing lines are arranged on the cylinder itself. Apart from one the total construction as well as naturally also assembly and maintenance complicated making arrangement such functional elements integral with or in the cylinder base, cover or tube, In this context, above all arrangements have proven in which block-like combined functional units on the cylinder bottom or in the area the cylinder bottom are placed. These function blocks are for this purpose too machined connecting surfaces screwed sealed, the necessary pressure medium connections via matching mouths of the corresponding lines the cooperating pads are made.
Druckmittelzylinder der genannten Art werden beispielsweise für sogenannte Zylinder-Speichereinheiten verwendet, wie sie zur Personensicherung bzw. Personenrückhaltung in Fahrgeschäften und dergleichen im Zusammenhang mit Sicherheitsbügeln oder ähnlichen Elementen eingesetzt werden. Im Gegensatz zu früher teilweise verwendeten mechanisch rastenden Systemen kann mit derartigen Druckspeichereinheiten eine stufenlose Bügelverstellung realisiert werden, wobei der im Gegensatz zu mechanischen Systemen vernachlässigbare Verschleiß zur Erhöhung der Sicherheit beiträgt. Das Öffnen des Sicherheitsbügels erfolgt über die während des Schließvorgangs in einem Druckspeicher am Funktionsblock gespeicherte Energie, wobei zur Sicherheit auch noch mehrere Einheiten pro Person eingesetzt werden können.Pressure medium cylinder of the type mentioned, for example, for so-called cylinder storage units used, as they are for personal security or people restraint in rides and the like in connection with safety bars or the like Elements are used. In contrast to earlier partially used mechanically latching systems can with such accumulator units a continuous ironing adjustment be realized, which in contrast to mechanical systems negligible Wear contributes to increasing safety. Opening the safety bar takes place during the closing process in a pressure accumulator on the function block stored energy, whereby for safety also several units per person used can be.
Ein gewisser Nachteil bei den bisher bekannten Ausführungen von Druckmittelzylindern der eingangs genannten Art ist in der trotz allen Vorteilen relativ aufwendigen und unflexiblen Ausbildung des Anschlusses des Funktionsblocks zu sehen, der auch im Hinblick auf Bauvolumen, Gewicht der Gesamtanordnung und Sicherheit bzw. Festigkeit der Verbindung optimierbar schien.A certain disadvantage in the previously known versions of pressure medium cylinders of the type mentioned is in spite of all the advantages relatively expensive and inflexible Training to see the connection of the function block, also with regard to Construction volume, weight of the overall arrangement and safety or strength of the connection seemed optimizable.
Aufgabe der vorliegenden Erfindung ist es, einen Druckmittelzylinder der eingangs genannten Art so zu verbessern, daß die erwähnten Nachteile der bekannten Anordnungen vermieden werden und daß insbesonders die Anordnung und Befestigung des aufgesetzten Funktionsblocks verbessert wird.Object of the present invention is to provide a pressure medium cylinder of the above mentioned type to improve so that the mentioned disadvantages of the known arrangements be avoided and that in particular the arrangement and attachment of the patch Function block is improved.
Die genannte Aufgabe wird bei einem Druckmittelzylinder der eingangs genannten Art gemäß der vorliegenden Erfindung dadurch gelöst, daß der Zylinderboden zumindest einen zylindrischen äußeren Anschlußbereich aufweist, in welchem die zu den Arbeitsräumen führenden Druckmittelleitungen nach außen münden und welcher in eine entsprechend abgedichtete Durchgangsbohrung des Funktionsblocks, in welche die Druckmittelleitungen der Funktions-elemente münden, eingesteckt und dort befestigt ist. Damit ist also der bisher stets einseitig am Zylinder bzw. Zylinderboden vorgesehen gewesene Anschlußbereich auf einen rundumlaufenden, zylindrischen äußeren Anschlußbereich am Zylinderboden erweitert, der in eine entsprechend abgedichtete Durchgangsbohrung des Funktionsblocks eingesteckt und dort befestigt ist, womit sich eine sehr stabile und damit auch sichere Konstruktion ergibt. Etwaige auftretende Kräfte zwischen dem Zylinder bzw. Zylinderboden und dem Funktionsblock werden damit in der Hauptsache direkt formschlüssig zwischen diesen Bauteilen übertragen und nicht wie bisher über Befestigungsschrauben oder ähnliche Elemente an den einseitigen Anschlußbereichen. The above object is in a pressure cylinder of the aforementioned Art according to the present invention achieved in that the cylinder bottom at least a cylindrical outer terminal region, in which the to the work spaces leading pressure medium lines open to the outside and which in a corresponding sealed passage bore of the function block into which the pressure medium lines of the functional elements open, plugged in and fixed there. So that is so far always one-sided am Cylinder or cylinder bottom has been provided connecting area on an all-round, extended cylindrical outer terminal area on the cylinder bottom, in a corresponding sealed through hole of the function block inserted and fastened there is, which results in a very stable and therefore safe construction. any occurring forces between the cylinder or cylinder bottom and the function block thus transferred in the main thing directly form-fitting between these components and not as before about mounting screws or similar elements on the one-sided terminal areas.
Gemäß einer besonders bevorzugten weiteren Ausgestaltung der Erfindung ist vorgesehen, daß der Zylinderboden insgesamt als mit dem Zylinderrohr koaxialer, abgedichtet verbundener, separater Drehteil ausgeführt ist, was die Herstellung des Zylinderbodens gegenüber den bisher erforderlichen Frästeilen wesentlich vereinfacht.According to a particularly preferred further embodiment of the invention is provided that the cylinder bottom as a whole coaxial with the cylinder tube, sealed connected, separate rotary part is executed, which is the production of the cylinder base opposite greatly simplified the previously required milled parts.
Die Druckmittelleitungen in der Durchgangsbohrung des Funktionsblocks und/oder am äußeren Anschlußbereich des Zylinderbodens münden nach einer weiters bevorzugten Ausgestaltung der Erfindung in umlaufende Ringausnehmungen, was auf sehr einfache Weise eine winkelmäßige Freiheit bei der Positionierung des Funktionsblocks relativ zum Zylinderboden bzw. zum Druckmittelzylinder ergibt. Wenn das Befestigungselement am Zylinderboden beispielsweise eine definierte Drehstellung des Zylinder festlegt, ist es mit dieser Ausgestaltung immer noch möglich, den Funktionsblock dazu beliebig winkelmäßig auf dem zylindrischen Anschlußbereich des Zylinderbodens verdreht zu fixieren, was für viele Anwendungen von Vorteil ist.The pressure medium lines in the through hole of the function block and / or at the outer terminal portion of the cylinder bottom open to a further preferred Embodiment of the invention in circumferential annular recesses, which in a very simple manner an angular freedom in the positioning of the functional block relative to the cylinder bottom or to the pressure cylinder results. When the fastener on the cylinder bottom For example, defines a defined rotational position of the cylinder, it is with this configuration still possible, the function block to arbitrarily angularly on the cylindrical Connection area of the cylinder bottom twisted to fix, which is the case for many applications is beneficial.
Der Zylinderboden ist in weiterer Ausgestaltung der Erfindung abgedichtet in das Zylinderrohr eingeschraubt, was Herstellung und Montage vereinfacht und nicht zuletzt wegen der oben beschriebenen Möglichkeit der winkelmäßig versetzten Montage des Funktionsblocks auch keine Positionierprobleme der Teile relativ zueinander ergibt.The cylinder bottom is sealed in a further embodiment of the invention in the cylinder tube screwed, which simplifies manufacture and assembly and not least because the above-described possibility of angularly offset mounting of the function block also no positioning problems of the parts relative to each other.
Das Befestigungselement für den Druckmittelzylinder ist nach einer weiters bevorzugten Ausgestaltung der Erfindung an der Außenseite des Zylinderbodens befestigt und vorzugsweise von einem eingeschraubten Schwenkauge gebildet. Auch dies erleichtert Herstellung und Montage des Zylinderbodens bzw. des Druckmittelzylinders insgesamt.The fastener for the pressure cylinder is after a further preferred Embodiment of the invention attached to the outside of the cylinder bottom and preferably formed by a screwed pivoting eye. This also facilitates production and assembly of the cylinder bottom and the pressure cylinder total.
In weiterer vorteilhafter Ausgestaltung der Erfindung kann vorgesehen sein, daß der aufgesetzte Funktionsblock mittels einer von der Außenseite her auf den Zylinderboden aufgeschraubten Befestigungsmutter befestigt ist. Dies ergibt eine sehr einfache Möglichkeit zur sicheren Befestigung des Funktionsblocks, wobei die Möglichkeit der oben angesprochenen nachträglichen Anbringung eines beispielsweise auch größeren Schwenkauges davon nicht beeinträchtigt wird.In a further advantageous embodiment of the invention can be provided that the attached functional block by means of a screwed onto the cylinder bottom from the outside Fixing nut is attached. This gives a very easy way to secure attachment of the functional block, with the possibility of the above-mentioned subsequent attachment of an example, even larger Schwenkauges not is impaired.
