Description

Die vorliegende Erfindung betrifft ein Schaltscharnier mit einem ersten, einen über einen Hebel betätigbaren Schalter aufnehmenden Scharnierflügel, einem zweiten Scharnierflügel und einer Welle, welche in Betriebsstellung verdrehsicher mit dem zweiten Scharnierflügel verbunden ist und an ihrem Umfang eine in Wellen-Achsrichtung verlaufende Schaltnut aufweist, in welche in einer vorbestimmten Schwenkstellung zwischen den beiden Scharnierflügeln ein mit dem Hebel verbundener Betätigungsstift eintaucht, wobei der Hebel parallel zur Wellen-Längsachse verläuft und gegenüber dieser verschwenkbar sowie durch eine Feder in Richtung der Welle belastet ist und im Bereich eines Schaltnockens oder Schaltstiftes des Schalters liegt.The present invention relates to a switching hinge with a first, an over a lever-operated switch receiving hinge wing, a second Hinge wing and a shaft, which in the operating position is secured against rotation with the second hinge wing is connected and on its circumference in the shaft axis direction has extending switching groove, in which in a predetermined Swivel position between the two hinge wings connected to the lever The actuating pin is immersed, with the lever parallel to the longitudinal axis of the shaft runs and can be pivoted relative to this and by a spring in the direction the shaft is loaded and in the area of a switch cam or switch pin Switch.

Schaltscharniere der vorerwähnten Art sind an sich bekannt und werden beispielsweise als Scharniere für Schutzhauben an Maschinen, Schutzraumtüren oder dergleichen verwendet. Dabei ist die Gesamtkonstruktion eines Schaltscharnieres so ausgelegt, dass die Einschalt-Stellung des Schalters ausschließlich bei geschlossener Schutzhaube oder Schutzraumtür gegeben ist. In dieser Situation greift der mit dem Hebel verbundene Betätigungsstift in die Schaltnut der Welle ein.Switch hinges of the type mentioned are known per se and are, for example as hinges for protective hoods on machines, shelter doors or the like used. The overall construction of a switching hinge is like this designed so that the switch is in the ON position only when the switch is closed Protective hood or protective room door is given. In this situation, he intervenes actuating pin connected to the lever into the switching groove of the shaft.

Wird nun die Schutzhaube oder Schutzraumtür geöffnet, führt eine damit einhergehende Verdrehung der Welle dazu, dass der Betätigungsstift aus der Schaltnut herausgedrückt und auf dem Außenumfang der Welle abgestützt wird. Dies wiederum führt zu einer Hebelbetätigung und damit auch zu einer Betätigung des Schaltnokkens oder des Schaltstiftes des Schalters, so dass dieser in seine Aus-Stellung gebracht wird.If the protective hood or shelter door is opened, an associated one will result Rotation of the shaft causes the actuating pin to be pushed out of the switching groove and is supported on the outer circumference of the shaft. this in turn leads to a lever actuation and thus also to an actuation of the shift cam or the switch pin of the switch so that it is brought into its off position becomes.

Aufgrund der verschiedensten, in der Praxis vorkommenden Einbausituationen für Schaltscharniere der gattungsgemäßen Art muß sichergestellt sein, dass das Erreichen der Einschalt-Stellung für den Schalter immer nur dann möglich ist, wenn eine Schutzhaube oder Schutzraumtür ihre Schließstellung einnimmt. Dabei können diese Schließstellungen durchaus die unterschiedlichsten Winkelstellungen der beiden Scharnierflügel zueinander zur Folge haben, weshalb bislang Schaltscharniere der gattungsgemäßen Art jeweils auftragsbezogen gefertigt wurden.Due to the wide variety of installation situations that occur in practice for Hinges of the generic type must be ensured that the reaching the switch-on position is only possible if one Protective hood or protective room door assumes its closed position. You can do this Closed positions are the most different angular positions of the two Hinge wings result in each other, which is why switching hinges generic type were each made to order.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Schaltscharnier der gattungsgemäßen Art zu schaffen, welches universell einsetzbar und an jeden denkbaren Anwendungsfall anpaßbar ist.The present invention has for its object a hinge Generic type to create, which can be used universally and at every conceivable Use case is customizable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Welle in einer Vormontagestellung, in welcher der Betätigungsstift in die Schaltnut eingreift, gegenüber dem ersten Scharnierflügel gegen Verdrehung gesichert und der zweite Scharnierflügel gegenüber der Welle frei verschwenkbar ist, dass die Welle durch eine in ein stirnseitiges Ende des ersten Scharnierflügels eingedrehte Einpaßschraube um ein vorbestimmtes Maß aus der Vormontagestellung heraus bis in die Betriebsstellung axial verschiebbar ist und dass die Welle mit einer gerändelten oder anderweitig strukturierten Ringzone versehen ist, die bei in Betriebsstellung verschobener Welle in einer Scharnierbohrung des zweiten Scharnierflügels zur Erzielung der Verdrehsicherung zwischen dem zweiten Scharnierflügel und der Welle formschlüssig eingepresst ist.This object is achieved in that the shaft in a pre-assembly position, in which the actuating pin engages in the switching groove, opposite the first hinge wing is secured against rotation and the second hinge wing is freely pivotable with respect to the shaft that the shaft by a in an end of the first hinge wing screwed in fitting screw a predetermined dimension from the pre-assembly position to the operating position is axially displaceable and that the shaft with a knurled or otherwise Structured ring zone is provided, the shifted in the operating position Shaft in a hinge hole in the second hinge wing to achieve the Anti-rotation lock between the second hinge wing and the shaft with a positive fit is pressed.

Ein derart gestaltetes Schaltscharnier bietet in der Praxis erhebliche Vorteile. Unabhängig von dem späteren, konkreten Einsatzfall kann ein derartiges Schaltscharnier werkseitig in seiner Vormontagestelltung zusammengefügt werden. Dieses Schaltscharnier kann nun vor Ort beispielsweise an einem ortsfesten Maschinenteil und einer demgegenüber beweglichen Schutzhaube befestigt werden, wobei in jedem Falle der Betätigungsstift des Hebels in die Schaltnut der Welle eingreift, wodurch die Einschalt-Stellung des Schalters vorgegeben ist. Dabei spielt es keine Rolle, welche Winkelstellung die beiden Scharnierflügel relativ zueinander einnehmen, da der zweite Scharnierflügel in dieser Vormontagestellung noch frei gegenüber der Welle verdrehbar ist.A switching hinge designed in this way offers considerable advantages in practice. Independently Such a switching hinge can be used for the later, specific application be assembled at the factory in its pre-assembly position. This hinge can now, for example, on a stationary machine part and a protective hood that can be moved against it, in each Case engages the actuating pin of the lever in the switching groove of the shaft, whereby the switch is in the on position. It doesn't matter which angular position the two hinge wings assume relative to each other, because the second hinge wing in this pre-assembly position is still free compared to the Shaft is rotatable.

Nach dem Verbinden des erfindungsgemäßen Schaltscharnieres wird nun in der Schließstellung einer Schutzhaube oder einer Schutzraumtür die Welle durch die Einpaßschraube bis in ihre Betriebsstellung hinein axial verschoben. Die gerändelte oder anderweitig strukturierte Ringzone wird dabei unter Erzielung eines Formschlusses in die Scharnierbohrung der zweiten Scharnierhälfte eingepresst. Nunmehr ist eine Verschwenkung des zweiten Scharnierflügels relativ zur Welle nicht mehr möglich. Nachdem die Verdrehsicherung zwischen dem ersten Scharnierflügel und der Welle aufgehoben ist, kann das Scharnier betätigt werden und ein Öffnen der Schutzhaube oder einer Schutzraumtür hat nun sofort zur Folge, dass die Welle gegenüber dem ersten Scharnierflügel verdreht und damit der mit dem Hebel verbundene Betätigungsstift aus der Schaltnut heraus bewegt wird. Damit nimmt der Schalter, wie oben schon erwähnt, seine Ausschalt-Stellung ein.After connecting the switching hinge according to the invention is now in the Closed position of a protective hood or a protective room door through the shaft Fit screw axially displaced into its operating position. The knurled one or otherwise structured ring zone is achieved with a positive fit pressed into the hinge hole of the second hinge half. Now is not a pivoting of the second hinge wing relative to the shaft more is possible. After the anti-twist device between the first hinge wing and the shaft is lifted, the hinge can be operated and opened the protective hood or a protective room door now has the immediate consequence that the Shaft rotated in relation to the first hinge wing and thus the one with the lever connected actuating pin is moved out of the switching groove. With that takes the switch, as already mentioned above, is in its off position.

Ein erfindungsgemäßer Scharnierschalter ist somit universell einsetzbar und in der Praxis problemlos für jeden nur denkbaren Anwendungsfall justierbar.A hinge switch according to the invention is thus universally applicable and in the Practice easily adjustable for every conceivable application.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen. Further features of the invention are the subject of dependent claims.

Das in den Figuren 1 bis 4 dargestellte und insgesamt mit dem Bezugszeichen 1 bezeichnete Schaltscharnier weist einen ersten Scharnierflügel 2 mit einer Hohlkammer 3 auf, innerhalb derer ein Schalter 4 angeordnet ist.The one shown in FIGS. 1 to 4 and generally designated by reference number 1 Switch hinge has a first hinge wing 2 with a hollow chamber 3, within which a switch 4 is arranged.

Weiterhin weist das Schaltscharnier 1 einen zweiten Scharnierflügel 5 und eine Welle 6 auf, über welche die beiden Scharnierflügel 2 und 5 miteinander verbunden sind.Furthermore, the switching hinge 1 has a second hinge wing 5 and one Shaft 6 on which the two hinge wings 2 and 5 are connected to each other are.

Diese Welle 6 ist in ihrem Umfangsbereich mit einer Schaltnut 7 ausgestattet, (s. Fig. 1) in welche ein Betätigungsstift 8 eintauchen kann, wenn die Welle 6 eine bestimmte Verdrehposition relativ zum ersten Scharnierflügel 2 einnimmt.This shaft 6 is equipped in its peripheral area with a switching groove 7, (see. Fig. 1) in which an actuating pin 8 can dip when the shaft 6 a certain Takes rotational position relative to the first hinge wing 2.

Der besagte Betätigungsstift 8 ist mit einem Hebel 9 verbunden, welcher parallel zur Wellen-Längsachse verläuft und gegenüber dieser verschwenkbar ist. Außerdem ist der Hebel 9 durch eine Feder 10 belastet, welche den besagten Hebel 9 ständig in Richtung der Welle 6 beaufschlagt. Said actuating pin 8 is connected to a lever 9 which is parallel runs to the longitudinal axis of the shaft and is pivotable relative to this. Moreover the lever 9 is loaded by a spring 10, which the said lever 9 constantly in Directed to the shaft 6.

Der Hebel 9 liegt im Bereich eines Schaltnockens oder Schaltstiftes 11 des Schalters 4 und kann somit diesen Schaltnocken oder Schaltstift 11 betätigen.The lever 9 is in the region of a switch cam or switch pin 11 of the switch 4 and can thus actuate this switching cam or switching pin 11.

Die Welle 6 ist mit einem Ihrer Enden in einer Scharnierbohrung 12 des ersten Scharnierflügels 2 und mit ihrem anderen stirnseitigen Ende in einer Aufnahmebohrung 13 einer Einpaßschraube 14 gelagert, welche in ein stirnseitiges Ende des ersten Scharnierflügels 2 eingeschraubt ist. Außerdem durchtritt die Welle 6 den zweiten Scharnierflügel 5 im Bereich einer Scharnierbohrung 15.The shaft 6 is with one of its ends in a hinge bore 12 of the first Hinge wing 2 and with its other end in a receiving hole 13 of a fitting screw 14, which is in a front end of the first Hinge wing 2 is screwed. In addition, the shaft 6 passes through the second hinge wing 5 in the area of a hinge bore 15.

In der in Figur 1 gezeigten Vormontagestellung greift der Betätigungsstift 8 in die Schaltnut 7 der Welle 6 ein. Die Welle 6 ist in dieser Vormontagestellung gegenüber dem ersten Scharnierflügel 2 gegen Verdrehung gesichert, und zwar im dargestellten Ausführungsbeispiel durch einen mit dem Scharnierflügel 2 fest verbundenem Mehrkantzapfen 16, der in einen stirnseitigen Schlitz 17 der Welle 6 eingreift.In the pre-assembly position shown in Figure 1, the actuating pin 8 engages in the Switch groove 7 of the shaft 6. The shaft 6 is opposite in this pre-assembly position the first hinge wing 2 secured against rotation, in the illustrated Embodiment by a fixed to the hinge wing 2 Polygonal pin 16 which engages in an end slot 17 of the shaft 6.

In der besagten Vormontagestellung gemäß Figur 1 ist der zweite Scharnierflügel 5 noch frei drehbar gegenüber der Welle 6.In the pre-assembly position according to FIG. 1, the second hinge wing 5 still freely rotatable with respect to shaft 6.

Die Welle 6 ist mit einer gerändelten (oder anderweitig strukturierten) Ringzone 18 versehen, die in der Vormontagestellung gemäß Figur 1 noch außerhalb der Scharnierbohrung 15 des zweiten Scharnierflügels 5 liegt.The shaft 6 has a knurled (or otherwise structured) ring zone 18 provided that in the preassembly position according to FIG. 1 still outside the hinge bore 15 of the second hinge wing 5.

Vor der Herbeiführung der endgültigen Betriebsstellung gemäß Figur 3 kann nun der Scharnierflügel 5 in eine beliebige Verschwenkposition relativ zum Scharnierflügel 2 gebracht werden, ohne das sich hierdurch die Position zwischen der Welle 6 und dem ersten Scharnierflügel 2 verändert. Ist die gewünschte Betriebsstellung des zweiten Scharnierflügels 5 erreicht, (entsprechend der Schließstellung beispielsweise einer Schutzhaube) so kann die Welle 6 durch Betätigen der Einpaßschraube 14 axial verschoben werden, wodurch die gerändelte oder anderweitig strukturierte Ringzone 18 unter Erreichung eines Formschlusses in die Scharnierbohrung 15 des zweiten Scharnierflügels 5 eingepresst wird. Nach Erreichen dieser entgültigen Montageposition gemäß Figur 3 kann der Schraubenkopf 19 der Einpaßschraube 14 abgeschert werden, was Figur 3 deutlich zeigt.Before bringing the final operating position according to Figure 3 can now the hinge wing 5 in any pivot position relative to the hinge wing 2 are brought, without this changing the position between the shaft 6 and the first hinge wing 2 changed. Is the desired operating position of the second hinge wing 5 reached (corresponding to the closed position, for example a protective cover), the shaft 6 can be operated by pressing the fitting screw 14 axially displaced, causing the knurled or otherwise structured ring zone 18 with a positive fit in the hinge bore 15 of the second hinge wing 5 is pressed. After reaching this final mounting position according to Figure 3, the screw head 19 of the fitting screw 14 are sheared off, which is clearly shown in FIG. 3.

Eine nun herbeigeführte Verschwenkung des zweiten Scharnierflügels 5 relativ zum ersten Scharnierflügel 2 führt nun zu einer Abscherung des Mehrkantzapfens 16, da durch konstruktive Maßnahmen das zwischen der gerändelten Ringzone 18 der Welle 6 und der Scharnierbohrung 15 des zweiten Scharnierflügels 5 übertragbare Drehmoment um ein vielfaches höher gewählt ist als das für die Abscherung des Mehrkantzapfens 16 gegenüber dem ersten Scharnierflügel 2 erforderliche Drehmoment.A now brought about pivoting of the second hinge wing 5 relative to first hinge wing 2 now leads to shearing of the polygonal pin 16 since by constructive measures that between the knurled ring zone 18 Shaft 6 and the hinge bore 15 of the second hinge wing 5 transferable Torque is selected many times higher than that for shearing the Polygonal pin 16 compared to the first hinge wing 2 required Torque.

Das Schaltscharnier ist nach dem Abscheren des Mehrkantzapfens 16 nun uneingeschränkt betriebsbereit und es ist ohne weiteres sichergestellt, dass der Betätigungsstift 8 in die Schaltnut 7 eingreift, wenn die voreingestellte Verschwenkposition des zweiten Scharnierflügels 5 gegenüber dem ersten Scharnierflügel 2 - entsprechend der Schließlage beispielsweise einer Schutzhaube - erreicht ist.The switching hinge is now unrestricted after the polygon pin 16 has sheared off ready for operation and it is easily ensured that the actuating pin 8 engages in the switching groove 7 when the preset pivot position of the second hinge wing 5 compared to the first hinge wing 2 - accordingly the closed position of a protective hood, for example.

Die Welle 6 ist im Bereich ihrer gerändelten oder anderweitig strukturierten Ringzone 18 oberflächengehärtet, wodurch einerseits das formschlüssige Einpressen in die Scharnierbohrung 15 erleichtert und andererseits der erzielte Formschluß langfristig gewährleistet ist.The shaft 6 is in the area of its knurled or otherwise structured ring zone 18 surface hardened, which on the one hand enables positive locking in the hinge bore 15 facilitates and on the other hand the positive locking achieved in the long term is guaranteed.

Abweichend vom dargestellten Ausführungsbeispiel wäre eine vorübergehende Verdrehsicherung zwischen Welle 6 und erstem Scharnierflügel 2 beispielsweise auch durch einen Stift möglich, der durch eine Bohrung innerhalb des ersten Scharnierflügels 2 bis in eine Querbohrung der Welle 6 eingeschoben wird. Dieser Stift könnte dann nach Herstellung der endgültigen Betriebsstellung entfernt werden. Gegebenenfalls wäre noch ein Abdichten der Bohrung durch den ersten Scharnierflügel 2 sinnvoll. Deviating from the illustrated embodiment would be a temporary one Anti-rotation device between shaft 6 and first hinge wing 2, for example also possible with a pin through a hole in the first hinge wing 2 is inserted into a transverse bore of the shaft 6. This pen could then be removed after the final operational position is established. If necessary, the bore would be sealed by the first hinge wing 2 makes sense.

Alternativ zu dem im Ausführungsbeispiel gezeigten, mechanisch betätigten Schalter kann das erfindungsgemäße Schaltscharnier natürlich auch mit optisch, induktiv, kapazitiv oder magnetisch wirkenden Sensoren zur Abtastung der Bewegung des Hebels 9 ausgestattet sein. Zur Erhöhung der Sicherheitsstufe kann dabei auch eine Kombination verschiedener Sensoren Verwendung finden.As an alternative to the mechanically operated switch shown in the exemplary embodiment can of course the switching hinge according to the invention also with optical, inductive, capacitive or magnetic sensors for sensing the movement of the Lever 9 be equipped. To increase the security level, a Combination of different sensors can be used.
