Description

Die Erfindung bezieht sich auf einen Schlüsselschalter mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a key switch with the features of the preamble of claim 1.

Bei einem bekannten Schlüsselschalter der eingangs genannten Art (DE-OS 28 56 337) ist ein Profilhalbzylinderschloß an dem Gehäusedeckel nur von innen her lösbar befestigt, dessen Schloßbart in Drehstellungen außerhalb einer bestimmten Drehstellung eine Zwischenplatte hintergreift, an der der Schalter festgelegt ist. Der Gehäusedeckel ist mit von außen zugänglichen Schrauben lösbar. Lediglich das weitere Öffnen des den Schalter enthaltenden Gehäuseinnenraumes ist nur dann möglich, wenn man voraussetzt, daß der Gehäusedeckel mit dem Schloß nicht verdrehbar ist, derart, daß die Schrauben, mit denen die Zwischenplatte an dem den Gehäuseboden umfassenden Gehäuse teil festgelegt ist, nicht zugänglich werden. Auf jeden Fall ist es einem Unbefugten möglich, ohne Schlüssel den Gehäusedeckel zu lösen, so daß selbst bei nicht weitergehender Zugänglichkeit zum Gehäuseinnenraum nachteilige Witterungseinflüsse platzgreifen. Im übrigen besteht dieser bekannte Schlüsselschalter aus einer Vielzahl von Bauelementen, was herstellungstechnisch einen entsprechenden Aufwand erfordert.In a known key switch of the type mentioned (DE-OS 28 56 337), a semi-cylinder lock is releasably attached to the housing cover only from the inside, the lock bit engages behind an intermediate plate in rotational positions outside of a certain rotational position, on which the switch is fixed. The housing cover can be removed with screws accessible from the outside. Only the further opening of the housing interior containing the switch is only possible if one assumes that the housing cover cannot be rotated with the lock in such a way that the screws with which the intermediate plate is fixed to the housing part comprising the housing base are not accessible will. In any case, it is possible for an unauthorized person to loosen the housing cover without a key, so that adverse weather influences can take hold even when there is no further access to the housing interior. Otherwise, this known key switch consists of a large number of components, which requires a corresponding outlay in terms of production technology.

Der Erfindung liegt die Aufgabe zugrunde, einen Schlüsselschalter der eingangs genannten Art zu schaffen, bei dem eine Öffnung des Gehäuses ohne Verdrehen des Schloßbartes in die bestimmte Drehstellung nicht möglich ist und der mit einem Minimum an Bauteilen erstellt ist.The invention has for its object to provide a key switch of the type mentioned, in which an opening of the housing without twisting the lock bit in the particular rotational position is not possible and which is created with a minimum of components.

Ausgehend von einem Schlüsselschalter mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen Kennzeichen gelöst.Starting from a key switch with the features of the preamble of claim 1, this object is achieved according to the invention by its characteristics.

Durch die erfindungsgemäße Ausbildung des Schlüsselschalters wird erreicht, daß das Gehäuse überhaupt nicht unbefugt geöffnet werden kann, so daß auch der Versuch, den Schlüssel schalter ohne Schlüssel zu bedienen, Witterungseinflüsse ausschließt, die zur Beeinträchtigung bzw. ungewollter Schaltfunktion führen können. Vor allem aber ist der Schalte erfindungsgemäß so ausgebildet, daß nur zwei Gehäuseteile erforderlich sind, die das Schloß und den Schalter aufnehmen so daß die Herstellung des erfindungsgemäßen Schalters entsprechend einfach und billig ist, was auch die erforderlichen Befestigungsteile betrifft.The inventive design of the key switch ensures that the housing can not be opened at all without authorization, so that the attempt to operate the key switch without a key excludes weather influences that can lead to impairment or unwanted switching function. Above all, however, the switch is designed according to the invention so that only two housing parts are required, which accommodate the lock and the switch, so that the manufacture of the switch according to the invention is correspondingly simple and cheap, as far as the required fastening parts are concerned.

Weitere bevorzugte Ausführungen der Erfindung ergeben sich aus den Unteransprüchen im Zusammenhang mit dem in der Zeichnung wiedergegebenen Ausführungsbeispiel, auf das besonders Bezug genommen wird und dessen nachfolgende Beschreibung die Erfindung näher erläutert. Es zeigen:

  • Figur 1 eine Draufsicht auf die Gehäusedeckelfrontseite des Ausführungsbeispieles;
  • Figur 2 einen Schnitt nach der Linie II-II in Figur 1;
  • Figur 3 eine Ansicht auf den den Gehäuseboden umfassenden Gehäuseteil mit dem Schalter im Gehäuseinnenraum;
  • Figur 4 einen Schnitt nach der Linie IV-IV in Figur 3 bei ungeschnittenem Schalter mit auf das den Gehäuseboden aufweisenden Gehäuseteil aufgesetztem Gehäusedeckel.
Further preferred embodiments of the invention result from the subclaims in connection with the exemplary embodiment shown in the drawing, to which particular reference is made and the following description of which explains the invention in more detail. Show it:
  • Figure 1 is a plan view of the front cover of the embodiment;
  • 2 shows a section along the line II - II in Figure 1;
  • FIG. 3 shows a view of the housing part comprising the housing base with the switch in the interior of the housing;
  • Figure 4 shows a section along the line IV-IV in Figure 3 with an uncut switch with the housing cover placed on the housing part having the housing cover.

Das insgesamt mit 1 bezeichnete Gehäuse besteht aus einem Gehäusedeckel 2 und einem den Gehäuseboden 3 umfassenden Gehäuseteil 4 (Figur 3). In Figur 2 ist das den Gehäuseboden 3 umfassende Gehäuseteil 4 nicht dargestellt. Andererseits ist ein Blendschild 5 wiedergegeben, das die Oberfläche des Gehäusedeckels 2 allseitig übergreift und für den Fall vorgesehen ist, daß das Schaltergehäuse 1 insgesamt in sogenannter Unterputz-Installation eingebaut ist. Im dargestellten Ausführungsbeispiel ist das den Gehäuseboden 3 umfassende Gehäuseteil 4 praktisch auf den Boden 3 beschränkt, der Gehäusedeckel 2 umgreift also den Gehäuseinnenraum 6 fast vollständig. Es ist aber ohne weiteres möglich, das den Gehäuseboden 3 umfassende Gehäuseteil 4 topfartig auszubilden, auf dessen Außenrand dann der praktisch flach ausgebildete Gehäusedeckel 2 aufsetzbar ist. Es kann auch jede andere Trennfugenebene zwischen der Frontoberfläche 7 des Gehäusedeckels 2 und dem Gehäuseboden 3 gewählt werden.The housing, designated overall by 1, consists of a housing cover 2 and a housing part 4 comprising the housing base 3 (FIG. 3). The housing part 3 comprising the housing base 3 is not shown in FIG. On the other hand, a shield 5 is shown, which overlaps the surface of the housing cover 2 on all sides and is provided in the event that the switch housing 1 is installed in a so-called flush-mounted installation. In the exemplary embodiment shown, the housing part 4 comprising the housing base 3 is practically limited to the base 3, that is to say the housing cover 2 encompasses the housing interior 6 almost completely. However, it is readily possible to design the housing part 4 comprising the housing base 3 in a pot-like manner, on the outer edge of which the practically flat housing cover 2 can then be placed. Any other parting line between the front surface 7 of the housing cover 2 and the housing base 3 can also be selected.

Die Draufsicht gemäß Figur 1 auf die Frontseite 7 des Gehäuse deckels 2 zeigt die Außenansicht des von außen zugänglichen Endes 8 des in eine Ausformung 9 des Gehäusedeckels 2 eingesetzten Profilhalbzylinderschlosses 10, wobei eine Gummidichtungsplatte 11, die in Figur 2 im Schnitt dargestellt ist, weggelassen wurde. Die Gummidichtungsplatte 11 ist kreisrund berandet und umgreift mit einer Ausnehmung das von außen zugängliche Ende 8 des Profilhalbzylinderschlosses 10 in dichter Zuordnung und ist in eine entsprechend kreisrund gestaltete Aussparung 12 derart eingepaßt, daß bei Aufschrauben des Blendschildes 5 und den dadurch auf die Gummidichtungsplatte ausgeübten Druck diese in dichtende Anlage an die Berandung der Aussparung 12 und diejenige des zugänglichen Endes 8 des Profilhalbzylinderschlosses 10 angepreßt wird.The top view of Figure 1 on the front 7 of the housing cover 2 shows the external view of the externally accessible end 8 of the profile half cylinder lock 10 used in a formation 9 of the housing cover 2, a rubber sealing plate 11, which is shown in section in Figure 2, has been omitted . The rubber sealing plate 11 has a circular rim and surrounds with a recess the end 8 of the profile half-cylinder lock 10 which is accessible from the outside in close association and is fitted into a correspondingly circular recess 12 in such a way that when the blind shield 5 is screwed on and the pressure exerted thereby is exerted on the rubber sealing plate in sealing contact to the edge of the recess 12 and that of the accessible end 8 of the profile half-cylinder lock 10 is pressed.

In Figur sind Gewindebohrungen 13 für Schrauben ersichtlich, die die Gummidichtungsplatte 11 durchgreifen und der Festlegung des Blendschildes 5 dienen, wodurch die vorerwähnte dichtende Einbettung der Gummidichtungsplatte 11 in die Aussparung 12 und an das Ende 8 des Profilhalbzylinderschlosses 10 erreicht wird.In the figure, threaded bores 13 for screws can be seen, which pass through the rubber sealing plate 11 and serve to fix the cover plate 5, as a result of which the aforementioned sealing embedding of the rubber sealing plate 11 in the recess 12 and at the end 8 of the profile half-cylinder lock 10 is achieved.

Die Ausformung 9 des Gehäusedeckels 2 (Figur 4) ist an die Querschnittsform des Profilhalbzylinderschlosses 10 angepaßt ausgebildet, so daß das Schloß in die Ausnehmung 9 leicht einsetzbar und entfernbar ist, ohne wesentliche Seitwärtsbewegungen ausführen zu können. Auch die Tiefe der Ausnehmung 9 ist entsprechend an das Schloß 10 angepaßt ausgebildet, obwohl das nicht wesentlich ist, jedoch wird dadurch die Bauhöhe des Schalters auf ein Minimum reduziert. Im Bodenbereich 14 der Ausnehmung 9 unterhalb des zylindrischen Teils des Profilhalbzylinderschlosses 10 ist eine Bohrung 15 vorgesehen, durch welche eine Schraube 16 geführt ist, die in ein Gewinde 17 eingeschraubt ist, das sich in einem Vorsprung 18 des Gehäusebodens 3 befindet. Die Schraube 16 ist demnach nur zugänglich, wenn das Profilhalbzylinderschloß 10 sich nicht in der Ausformung 9 befindet.The shape 9 of the housing cover 2 (Figure 4) is adapted to the cross-sectional shape of the profile half-cylinder lock 10, so that the lock in the recess 9 is easy to insert and remove without being able to perform significant sideways movements. The depth of the recess 9 is also adapted to the lock 10, although this is not essential, but this reduces the overall height of the switch to a minimum. In the bottom area 14 of the recess 9 below the cylindrical part of the semi-cylinder lock 10, a bore 15 is provided, through which a screw 16 is guided, which is screwed into a thread 17, which is located in a projection 18 of the housing base 3. The screw 16 is therefore only accessible when the semi-cylinder lock 10 is not in the formation 9.

Die Figuren 3 und 4 lassen erkennen, daß der Bart 19 des Schlosses 10 im Zuge seiner Verdrehbewegung in einer Ebene senkrecht zur Längsachse des Schloßzylinders eine in der Seitenwandung der Ausformung 9 des Gehäusedeckels 2 vorgesehene Öffnung 20 durchgreift, wenn das Schloß 10 in eine Verdrehstellung beaufschlagt ist, in der sich der Schloßbart außerhalb der Drehstellung 21 befindet, in der er sich fluchtend innerhalb des länglichen Schloßansatzes 22 befindet In diesen anderen Drehstellungen des Schloßbartes 19 - in Figur 3 strichpunktiert bei 23 und 24 wiedergegeben - läßt sich das Schloß 10 nicht aus der Ausformung 9 entfernen, weil der Schloßbart 19 die Berandung der Öffnung 20 hintergreift. Damit läßt sich das Schloß 10 nur dann aus der Ausformung 9 ausheben, wenn der Schloßbart 19 sich in einer bestimmten Drehstellung 21 befindet, in der er hinsichtlich des Schloßzylinderprofiles innerhalb des Schloßzylinderansatzes 22 gelegen ist.Figures 3 and 4 show that the beard 19 of the lock 10 in the course of its rotational movement in a plane perpendicular to the longitudinal axis of the lock cylinder passes through an opening 20 provided in the side wall of the formation 9 of the housing cover 2 when the lock 10 acts in a rotational position is, in which the lock bit is outside of the rotational position 21, in which it is in alignment within the elongated lock extension 22 In these other rotational positions of the lock bit 19 - shown in FIG. 3 by dash-dotted lines at 23 and 24 - the lock 10 cannot be removed from the formation 9 because the lock bit 19 engages behind the edges of the opening 20. Thus, the lock 10 can only be lifted out of the formation 9 when the lock bit 19 is in a certain rotational position 21, in which it is located within the lock cylinder extension 22 with respect to the lock cylinder profile.

Um im Zuge der regulären Betätigung des Schlosses 10 nicht Gefahr zu laufen, daß das Schloß aus der Ausformung 9 ausgleitet, ist dieses mit Hilfe einer Kugel 27 und einer Madenschraube 28 dadurch festgelegt, daß die Kugel 27 seitlich in eine Bohrung 29 im Ansatz 22 des Schlosses 10 eingreift, wenn die Madenschraube 28 entsprechend weit in eine Sacklochbohrung 30 eingedreht ist. Die Sacklochbohrung 30 ist parallel zur Längsachse des Schloßzylinders in der Einbaulage geführt und weist einen Bohrungsboden 31 auf, der hinsichtlich der Längsachse der Sacklochbohrung 30 schräg zum Gehäuseboden 3 hin abfallend ausgebildet ist und seitlich in einem Durchbruch 32 mündet, der auf die Bohrung 29 im Ansatz 22 des Schloßprofiles 10 ausgerichtet ist. (Figur 2 Die Kugel 27 ist im Durchmesser etwas größer als die Bohrung 29, so daß ein formschlüssiger Eingriff zwischen der Ausformung 9 und dem Schloß 10 über die Kugel 27 und die Bohrung 29 sichergestellt ist, so lange sich die Madenschraube 28 in entsprechender Verdrehposition befindet. Mit Zurückdrehen der Madenschraube kann die Kugel 27 in die Sacklochbohrung 30 hinein zurückweichen, so daß sich das Schloß 10 aus der Ausnehmung 9 bei entsprechender Stellung des Schloßbartes 19 herausnehmen läßt.In order not to run the risk of the lock sliding out of the formation 9 in the course of the regular actuation of the lock 10, this is fixed by means of a ball 27 and a grub screw 28 in that the ball 27 laterally into a bore 29 in the neck 22 of the Lock 10 engages when the grub screw 28 is screwed accordingly far into a blind hole 30. The blind hole 30 is guided parallel to the longitudinal axis of the lock cylinder in the installed position and has a hole bottom 31 which is designed to slope downwards with respect to the longitudinal axis of the blind hole 30 towards the housing base 3 and opens laterally into an opening 32 which leads to the hole 29 in the shoulder 22 of the lock profile 10 is aligned. (Figure 2 The ball 27 is slightly larger in diameter than the bore 29, so that a positive engagement between the formation 9 and the lock 10 via the ball 27 and the bore 29 is ensured as long as the grub screw 28 is in the corresponding rotational position When the grub screw is turned back, the ball 27 can retract into the blind hole 30, so that the lock 10 can be removed from the recess 9 with the corresponding position of the lock bit 19.

Wie Figur 1 erkennen läßt, ist die Sachlochbohrung 30 und damit die Madenschraube 28 durch die Gummidichtungsplatte 11 abgedeckt. Erst nach Entfernen dieser Dichtungsplatte 11 wird somit die Madenschraube 28 zugänglich. Löst ein Unbefugter diese Schraube ohne den Schlüssel für das Schloß zu besitzen, so kann er die Arretierung des Schlosses zwar aufheben, doch läßt sich das Schloß 10 so lange nicht aus der Ausnehmung 9 herausnehmen, so lange der Schloßbart 19 die nach oben gerichtete Berandung der Öffnung 20 in der Seitenwand der Ausnehmung 9 hintergreift.As can be seen in Figure 1, the blind hole 30 and thus the grub screw 28 is covered by the rubber sealing plate 11. Only after removing this sealing plate 11 is the grub screw 28 accessible. If an unauthorized person loosens this screw without having the key for the lock, he can release the lock from the lock, but the lock 10 cannot be removed from the recess 9 as long as the lock bit 19 has the upward edge of the Opening 20 engages in the side wall of the recess 9.

Der insgesamt mit 25 bezeichnete Schalter besteht im dargestellten Ausführungsbeispiel aus zwei Tastschalterelementen 33 und 34, die am Gehäuseboden 3 über einen vorspringenden Ansatz 35 festgelegt sind. Zwischen den Betätigungsgliedern 36, von denen nur eines dargestellt ist, und dem Schloßbart 1 sind Betätigungsstege 37 aus elastisch verformbaren Kunststoff vorgesehen, die an dem Gehäuseboden 3 bzw. entsprechenden Vorsprüngen 38 an diesem klemmend gehalten sind und die die Verdrehbewegung des Schloßbartes 19 an die Betätigungsglieder 36 der Tastschalterelemente 33, 34 weiterleiten.The switch, designated overall by 25, in the exemplary embodiment shown consists of two push-button elements 33 and 34, which are fixed to the housing base 3 via a projecting projection 35. Between the actuating members 36, only one of which is shown, and the lock bit 1, actuating webs 37 made of elastically deformable plastic are provided, which are held clamped on the housing base 3 or corresponding projections 38 on the latter and which prevent the twisting movement of the lock bit 19 on the actuating members 36 forward the key switch elements 33, 34.

Der Gehäusedeckel 2 greift über eine Dichtlippe 39 an dem anderen, den Gehäuseboden 3 umfassenden Gehäuseteil 4 an, so daß insgesamt eine dichte Gehäuseausbildung sichergestellt werden kann. Die elektrische Zuführungsleitung wird durch eine im Gehäuseboden 3 oder einer der Seitenwandungen des Gehäusedeckels 2 ausgebildete Kabeldurchführung 40 dichtend geleitet, wie dies an sich bekannt ist. An zwei diagonal einander gegenüber liegendenden Eckbereichen des Gehäusebodens 3 sind Befestigungsbohrungen 41 vorgesehen, über welche das Gehäuse in Aufputz- oder Unterputz-Installation an eine Wand oder dergleichen anschraubbar ist. Der mi der Dichtleiste 39 versehene Rand, der vom Gehäuseboden 3 aus gesehen aufwärts strebend ausgebildet ist, verläuft derart, daß die Befestigungsöffnungen 41 außerhalb des Gehäuses liegen, obwohl die Grundform des dem Gehäuseboden 3 aufweisenden Gehäuseteils 4 auch im Bodenbereich rechteckig bleibt.The housing cover 2 engages via a sealing lip 39 on the other housing part 4 comprising the housing base 3, so that overall a tight housing formation can be ensured. The electrical supply line is sealingly guided through a cable bushing 40 formed in the housing base 3 or one of the side walls of the housing cover 2, as is known per se. Fastening holes 41 are provided on two diagonally opposite corner regions of the housing base 3, via which the housing can be screwed onto a wall or the like in a surface or flush-mounted installation. The Mi the sealing strip 39 provided edge, which is designed to strive upward from the housing bottom 3, runs in such a way that the fastening openings 41 lie outside the housing, although the basic shape of the housing part 3 having the housing bottom 3 also remains rectangular in the bottom region.
