Herkömmliche Arretiermechanismen funktionieren reibschlüssig mithilfe von Keilen oder anderen Klemmgliedern oder auch formschlüssig durch Eingriff von Klinken, Haken, Klauen od. dgl. in Rastenelemente, wie Ausnehmungen, Haken od. dgl. In der Regel sind die herkömmlichen Verriegelungsvorrichtungen hinsichtlich Konstruktion und Funktionsweise auf eine spezielle Hubvorrichtung ausgerichtet und konzipiert.In lifting systems for lifting and holding heavier loads locking devices are available in a variety of different versions, with which the support elements of the respective lifting system can be determined together with the overlying load in predetermined stroke positions and secured against unintentional lowering or falling. Conventional locking mechanisms operate frictionally by means of wedges or other clamping members or positively by engagement of pawls, hooks, claws od. Like. In locking elements, such as recesses, hooks od. Like. In general, the conventional locking devices in terms of design and operation on a special Lifting device aligned and designed.

Aufgabe der Erfindung ist es, eine Verriegelungsvorrichtung zum lösbaren Arretieren von relativ bewegbaren Bauteilen insbesondere an Hubvorrichtungen zu schaffen, die für unterschiedliche Arten von Hubvorrichtungen und Hebesystemen geeignet ist.The object of the invention is a locking device for releasably locking relatively movable components in particular to provide lifting devices that is suitable for different types of lifting and lifting systems.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Klinkenmechanismus ein formsteifes langgestrecktes Gehäuse aufweist, das in seinem mittleren Bereich über ein Schwenklager an dem einen Bauteil montiert ist, dass im vorderen Bereich und im hinteren Bereich des langgestreckten Gehäuses je eine Klinke mit einem oder mehreren Zähnen verschwenkbar gelagert ist und dass der Stellantrieb mechanische Übertragungsglieder zum gemeinsamen Betätigen der beiden voneinander in Längsrichtung beabstandeten Klinken aufweist.This object is achieved in that the latch mechanism comprises a dimensionally stable elongated housing which is mounted in its central region via a pivot bearing on the one component that in the front region and in the rear region of the elongated housing each have a pawl with one or more teeth is mounted pivotably and that the actuator mechanical transmission members for jointly actuating the two spaced apart from each other in the longitudinal direction pawls.

Die schwenkbare Lagerung des formsteifen Gehäuses an dem einen Bauteil ermöglicht eine selbsttätige Ausrichtung des Gehäuses und damit auch der darin eingebauten Klinken zur Lage und Ausrichtung der an dem anderen Bauteil festmontierten Rasten. Diese selbsttätige Lageanpassung gewährleistet einen zuverlässigen Eingriff der in Längsrichtung voneinander beabstandeten und zu beiden Seiten des Schwenklagers angeordneten Klinken in die Halteelemente, wie Ausnehmungen, Anschläge etc. der Rasten. Die gleichzeitige und gemeinsame Betätigung der beiden voneinander in Längsrichtung beabstandeten Klinken mithilfe der mit dem Stellantrieb verbundenen mechanischen Übertragungsglieder gewährleistet eine sichere und mehrfache Fixierwirkung des Klinkenmechanismus, da durch schwenkbare Lagerung des Gehäuses und gleichzeitiges Aktivieren der Klinken-Verschwenkung sichergestellt wird, dass die Klinken auch bei nicht voll exakter gegenseitiger Ausrichtung der beiden zu arretierenden Bauteile sicher funktionieren.The pivotable mounting of the dimensionally stable housing on the one component allows an automatic alignment of the housing and thus also the pawls incorporated therein for the position and orientation of the fixedly mounted on the other component notches. This automatic position adjustment ensures a reliable engagement of the longitudinally spaced apart and arranged on both sides of the pivot bearing pawls in the holding elements, such as recesses, stops, etc. of the detents. The simultaneous and joint operation of the two spaced apart longitudinally pawls using the mechanical transmission links connected to the actuator ensures a secure and multiple fixing the latch mechanism, as is ensured by pivotal mounting of the housing and simultaneous activation of the pawl pivoting that the pawls also at not fully accurate mutual alignment of the two components to be locked work safely.

Gemäß einer zweckmäßigen Ausgestaltung der Erfindung weisen die mechanischen Übertragungsglieder jedes Klinkenmechanismus mindestens einen mit dem Stellantrieb gekoppelten langgestreckten Schieber auf, der im Gehäuse längsverschiebbar gelagert ist, dessen Mittelteil das Schwenklager überbrückt und an dessen Endteilen - Druckstücke zum Betätigen je einer Klinke ausgebildet sind. Dieser kostengünstig aus einem biegeverformten Stahlblech hergestellte langgestreckte Schieber gewährleistet durch die Überbrückung des mittleren Schwenklagers die gleichzeitige Betätigung der Klinken und zwar unabhängig von der Ausrichtung des Gehäuses zum zentralen Schwenklager.According to an expedient embodiment of the invention, the mechanical transmission members of each latch mechanism at least one coupled to the actuator elongated slide, which is mounted longitudinally displaceable in the housing, the middle part bridges the pivot bearing and at the end parts - pressure pieces are formed for actuating a respective pawl. This cost-effective made of a bent sheet steel elongated slide ensures the bridging of the central pivot bearing the simultaneous operation of the pawls, regardless of the orientation of the housing to the central pivot bearing.

Gemäß einer anderen vorteilhaften Ausgestaltung weisen die auf Zapfen drehbar gelagerten Klinken an ihrer Rückseite je ein angeformtes Druckstück auf, an denen der Schieber angreift, um bei Betätigen des Stellantriebes die Zähne der Klinken aus dem Eingriff mit den Rasten auszurücken. Zweckmäßig werden die Klinken durch Federkraft in ihre Eingriffsposition in den Rasten verschwenkt und werden in dieser Eingriffsposition gehalten, bis durch Aktivieren des Stellantriebs eine Rückschwenkung der Klinken in ihre Ausgangsposition erfolgt.According to another advantageous embodiment, the pawls rotatably mounted on pins on its back ever an integrally formed pressure piece on which the slider engages to disengage the teeth of the pawls from the engagement with the catches on actuation of the actuator. Appropriately, the pawls are pivoted by spring force into its engaged position in the detents and are held in this engaged position until a return pivoting of the pawls takes place in their starting position by activating the actuator.

Bei Verwendung eines durch ein Druckmittel, wie Hydrauliköl oder Druckluft, betätigten Stellantriebes, ist es zweckmäßig, den Zylinder dieses Stellantriebes an einer endseitigen Stirnfläche des Gehäuses zu befestigen und die Kolbenstange mit dem Endstück des Schiebers zu verbinden, z.B. durch eine Schraube, eine Niete od. dgl.. Statt des Druckmittelstellantriebs können selbstverständlich auch andere Antriebsaggregate, beispielsweise mechanisch betätigte Stellantriebe oder auch elektromagnetische Stellantriebe sowie Kombinationen verwendet werden.When using a by a pressure medium, such as hydraulic oil or compressed air actuated actuator, it is expedient to attach the cylinder of this actuator to an end face of the housing and the piston rod with the tail of the slider to connect, for example by a screw, a rivet od Likewise .. Instead of the pressure medium actuator can of course also Other drive units, such as mechanically actuated actuators or electromagnetic actuators and combinations are used.

Die in den Figuren 1 und 2 dargestellte Verriegelungsvorrichtung enthält einen Klinkenmechanismus 1, der an einem Bauteil 2 verschwenkbar gelagert ist, und einen Rastenmechanismus 3, der in Form einer stabilen Zahnstange großflächig an dem zweiten Bauteil 4 befestigt ist. Die Bauteile 2 und 4 sind in Fig. 2 lediglich schematisch angedeutet.The in the Figures 1 and 2 illustrated locking device includes a latching mechanism 1 which is pivotally mounted on a component 2, and a detent mechanism 3, the large area in the form of a stable rack on the second component 4 is attached. The components 2 and 4 are in Fig. 2 indicated only schematically.

Der Klinkenmechanismus 1 enthält ferner ein langgestrecktes Gehäuse 5 von etwa rechteckigem Querschnitt, das in seinem mittleren Bereich eine Querbohrung aufweist, in der eine Lagerbuchse 6 sitzt. In diese Lagerbuchse 6 greift ein Endzapfen 7 einer Achse 8 ein, der Teil des Schwenklagers ist und das Bauteil 2 trägt.The latch mechanism 1 further includes an elongated housing 5 of approximately rectangular cross-section, which has in its central region a transverse bore in which a bearing bush 6 is seated. In this bushing 6 engages an end pin 7 of an axle 8, which is part of the pivot bearing and the component 2 carries.

An dem in Fig. 1, 2 unteren Ende des Gehäuses 5 ist an der Stoßfläche ein Stellantrieb 10 befestigt, der bei dem dargestellten Ausführungsbeispiel einen über eine Schleppleitung 11 mit einem Druckmittel versorgten Zylinder 12 enthält, in dem ein Kolben 13 verschiebbar aufgenommen ist. An dem aus dem Zylinder 12 herausragenden Ende der Kolbenstange 14 ist ein Schieber 15 befestigt, der aus einer langgestreckten und biegegeformten Stahlplatte besteht und in einem Freiraum 16 des Gehäuses 5 in Längsrichtung verschiebbar gelagert ist. Dieser Schieber 15 wird in Richtung des Doppelpfeils in Fig. 1 durch Betätigen des Stellantriebs 12 verschoben.At the in Fig. 1, 2 lower end of the housing 5, an actuator 10 is attached to the abutting surface, which contains in the illustrated embodiment, a supplied via a trailing line 11 with a pressure medium cylinder 12, in which a piston 13 is slidably received. At the end protruding from the cylinder 12 end of the piston rod 14, a slider 15 is fixed, which consists of an elongated and bent-shaped steel plate and is slidably mounted in a free space 16 of the housing 5 in the longitudinal direction. This slide 15 is in the direction of the double arrow in Fig. 1 moved by actuating the actuator 12.

Wie aus Fig. 2 ersichtlich, sind in dem Gehäuse 5 sind zwei Klinken 20, 21 um je einen Zapfen 22, 23 um vorgegebene Winkelbeträge verschwenkbar gelagert. Diese Klinken weisen an ihrer der Zahnstange 3 zugekehrten Seite jeweils zwei beabstandete Zähne 24, 25 auf, die so gestaltet sind, dass sie formschlüssig in entsprechende Zahnlücken 26 der Zahnstange eingreifen können. Das Schwenk- bzw. Lagerzentrum der beiden Zahnklinken 20, 21 befindet sich in den beiden im jeweils oberen Klinkenteil angeordneten.How out Fig. 2 it can be seen, are in the housing 5, two pawls 20, 21 about a respective pin 22, 23 pivotably mounted by predetermined angular amounts. These pawls have on their side facing the rack 3 each two spaced teeth 24, 25 which are designed so that they can positively engage in corresponding tooth gaps 26 of the rack. The pivoting or bearing center of the two toothed pawls 20, 21 is located in the two in the respective upper pawl part.

Drehzapfen 22, 23. Wie aus Fig. 2 ersichtlich, ist an dem oberen linken Ende jeder Zahnklinke 20, 21 jeweils ein Ansatz 28, 29 angeformt, der einen Begrenzungsanschlag für die Schwenkbewegung der jeweiligen Zahnklinke 20, 21 bildet. Daneben greifen an jedem dieser Ansätze 28, 29 Betätigungsteile des Schiebers 15 an, sodass durch eine Längsverschiebung dieses Schiebers 15 in Fig. 2 nach oben die beiden Klinken 20, 21 gemeinsam um ihre Lagerzapfen 22, 23 nach links verschwenkt und damit außer Eingriff aus der Verzahnung 26 der Zahnstange 4 gebracht werden. An der Außenseite der Ansätze 28 greift je eine Feder, z.B. eine Teller- oder Blattfeder 30, 31 an, welche gegen den zugehörigen Ansatz 28, 29 drückt und eine Kraft bzw. Vorspannung auf die Klinken 20, 21 ausübt, um diese in ihre Eingriffsstellung - entgegen den eingezeichneten Pfeilen - zu verschenken und zu halten.Trunnions 22, 23. Like out Fig. 2 can be seen, at the upper left end of each toothed pawl 20, 21 each have a projection 28, 29 formed, which forms a limit stop for the pivoting movement of the respective toothed pawl 20, 21. In addition, engage on each of these lugs 28, 29 actuating parts of the slider 15, so that by a longitudinal displacement of this slide 15 in Fig. 2 to the top, the two pawls 20, 21 pivoted together about their bearing pins 22, 23 to the left and thus disengaged from the teeth 26 of the rack 4 are brought. On the outside of the lugs 28 each engages a spring, for example a plate or leaf spring 30, 31, which presses against the associated projection 28, 29 and a force or bias on the pawls 20, 21 exerts this in their engaged position - to give away and hold contrary to the indicated arrows.

An der einen oder auch an beiden Außenseiten des Gehäuses 5 können in Fig. 1, 2 gestrichelt angedeutete Gleitplatten 40 montiert sein, welche die Gleitreibung bei den Verschiebebewegungen des Gehäuses 5 auf dem zweiten Bauteil vermindern.At one or both sides of the housing 5 can in Fig. 1, 2 Dashed lines indicated sliding plates 40 may be mounted, which reduce the sliding friction in the displacement movements of the housing 5 on the second component.

Bei dem in Fig. 1, 2 dargestellten Ausführungsbeispiel sind die Klinken 20, 21 an ihren von der Schwenklagerung beabstandeten Ende mit jeweils zwei Zähnen 24, 25 versehen, die gleichzeitig in entsprechende Zahnausnehmungen der Zahnschiene 3 eingreifen. Die Klinken 20, 21 ebenso wie die an ihnen angeformten Zähne 24, 25 bestehen aus einem Sintermaterial und müssen demzufolge nicht oder nur in geringem Umfang spanend bearbeitet werden. Darüberhinaus haben Formkörper aus Sintermaterialien eine hohe Festigkeit und sind außerordentlich verschleißfest. Die zum gleichzeitigen Entriegeln der Klinken 20, 21 erforderlichen Kräfte sind wesentlich geringer als die bei herkömmlichen Verriegelungsmechanismen von Hubeinrichtungen erforderlichen Entriegelungskräfte, die regelmäßig nur von hydraulischen Stellantrieben aufgebracht werden können. Beim Erfindungsgegenstand sind pneumatische und/oder auch hydraulische Stellantriebe von relativ kleinen Dimensionen möglich.At the in Fig. 1, 2 illustrated embodiment, the pawls 20, 21 are provided at their spaced from the pivot bearing end with two teeth 24, 25, which engage simultaneously in corresponding tooth recesses of the toothed rail 3. The pawls 20, 21 as well as the teeth 24, 25 integrally formed on them are made of a sintered material and consequently do not need to be machined or only to a limited extent machined. In addition, shaped bodies made of sintered materials have a high strength and are extremely resistant to wear. The at the same time Unlocking the pawls 20, 21 required forces are much lower than the unlocking forces required in conventional locking mechanisms of lifting devices that can be applied regularly only by hydraulic actuators. In the subject invention pneumatic and / or hydraulic actuators of relatively small dimensions are possible.
