Description

Die Erfindung betrifft einen Beschlag gemäß Gattungsbegriff des Hauptanspruchs.The invention relates to a fitting according to the preamble of the main claim.

Ein Beschlag dieser Art ist bereits in Vorschlag gebracht worden, wobei das Zusatzschloss als ein mit einem Riegelglied versehener Druckzylinder ausgebildet ist. Das Riegelglied greift in der die Schließzylinder-Aufnahmeöffnung überdeckenden Verschlußlage des Schiebedeckels in eine Vertiefung der Grundplatte ein und sichert damit die Verschlußlage des Schiebedeckels. Ein derartiger Aufbau ist handhabungstechnisch ungünstig, da zum Schließen des Schiebedekkels eine Betätigung des Zusatzschlosses erforderlich ist.A fitting of this type has already been proposed, the additional lock being designed as a pressure cylinder provided with a locking member. The locking member engages in the locking position of the sliding cover covering the sliding cover in a recess of the base plate and thus secures the locking position of the sliding cover. Such a construction is unfavorable in terms of handling, since the additional lock must be actuated to close the sliding cover.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Beschlag der in Rede stehenden Art von schließtechnisch sicherem Aufbau anzugeben derart, daß dessen Handhabung vereinfacht ist.The invention is based on the object of specifying a fitting of the type in question of a lock-safe structure in such a way that its handling is simplified.

Gelöst wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1. Die Unteransprüche betreffen vorteilhafte Weiterbildungen des Gegenstands des Anspruchs 1.This object is achieved by the features of the characterizing part of claim 1. The subclaims relate to advantageous developments of the subject matter of claim 1.

Zufolge derartiger Ausgestaltung ist ein Beschlag von besonders einfacher Handhabung angegeben. Durch die erfindungsgemäße Ausgestaltung, das Riegelglied federbelastet auszugestalten, tritt beim Schließen des Schiebedeckels der Effekt ein, daß sich das Riegelglied aufgrund der Federvorspannung rastend hinter die Sperrstufe verlagert. Es ist demnach nicht erforderlich, eine Betätigung des Zusatzschlosses zum Schließen des Schiebedeckels vorzunehmen. Lediglich zum Öffnen des Schiebedeckels ist erfindungsgemäß der Hintergriff von Sperrstufe und Riegelglied durch Betätigung des Zusatzschlosses aufzuheben.As a result of such a configuration, a fitting of particularly simple handling is specified. Due to the design according to the invention of designing the locking member to be spring-loaded, when the sliding cover is closed, the effect occurs that the locking member is shifted behind the locking step due to the spring preload. It is therefore not necessary to operate the additional lock to close the sliding cover. Only to open the sliding cover, the rear engagement of the locking step and locking member is to be released by actuating the additional lock.

Nach einer Weiterbildung der Erfindung ist vorgesehen, daß die Sperrstufe von einer an der Unterseite des Schiebedekkels gelegenen Sperröffnung gebildet ist. In diesem Falle tritt das federdruckbelastete Riegelglied beim Schließen des Schiebedeckels in die Sperröffnung ein, deren Wandungsbereich die Sperrstufe bildet.According to a development of the invention, it is provided that the blocking step is formed by a blocking opening located on the underside of the sliding cover. In this case, the spring-loaded locking member enters the locking opening when the sliding cover is closed, the wall area of which forms the locking step.

Vorzugsweise ist ein zusatzschloßbetätigbares, schiebedeckelseitiges Freigabeglied vorgesehen, das in die Sperröffnung zur Riegelgliedbeaufschlagung in die den Schiebedeckel freigebende Rücktrittstellung verlagerbar ist. Diese Ausbildung hat den Vorteil, daß das Zusatzschloß von Sperrkräften entlastet ist. Es ist damit ein Beschlag von erhöhtem Sicherheitswert gegeben. Das Zusatzschloß dient ausschließlich zur Steuerung des Freigabegliedes, um mittels desselben in der Verschlußlage des Schiebedeckels das in Vortrittsstellung federbelastete Riegelglied der Grundplatte in die Rücktrittsstellung zu bewegen. Auf diese Weise wird das Riegelglied außer Eingriff mit der an der Unterseite des Schiebedeckels befindlichen Sperröffnung gebracht, was die anschließende Verlagerung des Schiebedeckels in die offene Stellung zuläßt. Da das grundplattenseitig geführte, in Vortrittsstellung federbelastete Riegelglied die Sperrkräfte aufnimmt, können weniger stark dimensionierte Zusatzschlösser einge setzt werden. Es lassen sich auch mit Vorteil Magnetschlösser vorsehen. Das Riegelglied selbst kann so beschaffen sein, daß es im Gegensatz zu bekannten Zusatzschlössern höher belastbar ist.Preferably, an additional lock-actuable, sliding cover-side release member is provided, which can be displaced into the blocking opening for acting on the locking member in the withdrawal position releasing the sliding cover. This training has the advantage that the additional lock is relieved of locking forces. There is therefore a fitting of increased security value. The additional lock is used exclusively to control the release member in order to move the locking member of the base plate which is spring-loaded in the forward position into the withdrawn position by means of the same in the closed position of the sliding cover. In this way, the locking member is brought out of engagement with the locking opening located on the underside of the sliding cover, which permits the subsequent displacement of the sliding cover into the open position. Since the locking element guided on the base plate side and spring-loaded in the forward position absorbs the locking forces, additional locks with less dimensions can be used. Magnetic locks can also be provided with advantage. The locking element itself can be designed in such a way that, in contrast to known additional locks, it can be subjected to higher loads.

Alternativ kann auch vorgesehen sein, daß das Zusatzschloß ein mit in Schließrichtung des Schiebedeckels weisender Auflaufschräge versehenen, durch Schlüsselbetätigung umlegbaren Sperrhaken aufweist. Auch hierdurch ist eine einfache Handhabung gewährleistet. Der aufgerichtete Sperrhaken drükkt mit seiner Auflaufschräge beim Schließen des Schiebedekkels das federbelastete Riegelglied nieder und überfährt es. Das Riegelglied springt nach dem Überfahren zurück und gelangt somit in den Hintergriff des Sperrhakens. Eine Zusatzschloßbetätigung ist hierzu nicht erforderlich. Soll der Schiebedeckel in Offenstellung verbracht werden, so erfolgt durch Schlüsselbetätigung ein Umlegen des Sperrhakens, so daß dieser an dem federbelasteten Riegelglied durch Verlagerung des Schiebedeckels vorbeigeführt wird.Alternatively, it can also be provided that the additional lock has a locking hook which is provided with an inclined bevel in the closing direction of the sliding cover and can be folded over by key actuation. This also ensures easy handling. The erected locking hook presses down the spring-loaded locking element with its ramp and closes the sliding cover and runs over it. The locking element springs back after being run over and thus gets into the rear grip of the locking hook. An additional lock actuation is not necessary for this. If the sliding cover is to be moved to the open position, the locking hook is flipped over by key actuation, so that it is guided past the spring-loaded locking element by moving the sliding cover.

Eine Doppelfunktion erfüllt das Riegelglied in Verbindung mit dem an der Schiebedeckel-Unterseite befindlichen Anschlag. Dieser tritt bei der Öffnungsverlagerung des Schiebedeckels, den Öffnungsweg begrenzend, vor das grundplattenseitige Riegelglied.The locking element fulfills a double function in connection with the stop located on the underside of the sliding cover. When the sliding cover is moved, this limits the opening path in front of the locking element on the base plate side.

Damit bei der Zurückverlagerung des Schiebedeckels das Riegelglied wieder in die an der Unterseite des Schiebedeckels angeordnete Sperröffnung gelangt, ist zwischen dem Anschlag und der Sperröffnung eine vom Anschlag ausgehende, in Richtung der Sperröffnung auf Unterseitenniveau ansteigende Auflaufschräge für das Riegelglied vorgesehen.So that when the sliding cover is moved back, the locking member again comes into the locking opening arranged on the underside of the sliding cover, an upward slope from the stop, rising in the direction of the locking opening to the underside level, is provided for the locking member between the stop.

Eine störungsfreie Verriegelungsfunktion ist dadurch gewährleistet, daß das Riegelglied als in einer stufenförmig abgesetzten Ausnehmung der Grundplatte verschieblich gelagerter, mit einem dem Sperrende gegenüberliegenden Ringkragen versehener Schließzapfen ausgebildet ist. Der Ringkragen dient dabei zur Begrenzung der Vortrittssteilung des Schließzapfens, indem er sich in dieser an der Stufe der Ausnehmung abstützt.A trouble-free locking function is ensured in that the locking member is designed as a locking pin which is displaceably mounted in a stepped recess in the base plate and is provided with an annular collar opposite the locking end. The ring collar serves to limit the pitch of the locking pin by being supported in the recess at the step thereof.

Zur Vortrittsbelastung des Schließzapfens bzw. des Riegelgliedes dient die sich am ringkragenseitigen Stirnende des Schließzapfens einerends abstützende Druckfeder, die andererends ihre Abstützung durch den in die Ausnehmung eingeschraubten Gewindeverschlußstopfen erhält. Mittels desselben ist es sogar möglich, die Federvorspannung einzustellen. Der Gewindeverschlußstopfen ist jedoch so in der Ausnehmung geführt, daß er sich nicht ungewollt verdreht. Vielmehr bedarf dieses des Ansetzens eines Schraubwerkzeuges, beispielsweise der Klinge eines Schraubendrehers.The front load on the locking pin or the locking member is provided on the end of the locking pin on the ring collar-side end of the compression spring, which is supported at the other end by the screwed screw plug in the recess. By means of the same it is even possible to adjust the spring preload. However, the threaded plug is guided in the recess so that it does not twist unintentionally. Rather, this requires the attachment of a screwing tool, for example the blade of a screwdriver.

Das ballige Ende des Schließzapfens erlaubt sogar dann eine Verlagerung des Schiebedeckels in die Offenstellung, falls mittels des zusatzschloßbetätigbaren Freigabegliedes das Sperrglied nicht vollständig zurückgedrückt wurde. In der Anfangsphase der entsprechenden Verschiebebewegung erfolgt durch das ballige Sperrende die vollständige Verlagerung des Riegelgliedes in die Rücktrittsstellung, und zwar durch die entsprechende Kante der Sperröffnung.The crowned end of the locking pin even allows the sliding cover to be shifted into the open position if the locking member has not been pushed back completely by means of the release member which can be actuated by the additional lock. In the initial phase of the corresponding displacement movement, the spherical locking end causes the locking member to be completely displaced into the back step position, namely through the corresponding edge of the barrier opening.

Bautechnische Vorteile bringt es, daß das Freigabeglied als ein einen in den Boden der Sperröffnung mündenden Kanal durchsetzender Stößel gestaltet ist. Durch Zusatzschloßbetätigung erfolgt einhergehend eine Verlagerung des Stößels und damit die Aussteuerung des Sperrgliedes in die Rücktrittsstellung. Der Stößel kann fest mit dem Zusatzschloß verbunden sein.There are structural advantages in that the release member is designed as a plunger passing through a channel opening into the bottom of the blocking opening. By actuating the additional lock, the plunger is shifted and thus the locking member is driven into the withdrawal position. The plunger can be firmly connected to the additional lock.

Von Vorteil ist es, daß das Zusatzschloß als Magnetschloß ausgebildet ist, das rückseitig ausladend diesen Stößel aufweist. Wird der entsprechende Magnetschlüssel dem Magnetschloß zugeordnet, so kann dieses in Einwärtsrichtung entgegen der Belastung einer Druckfeder verlagert werden verbunden mit einer gleichzeitigen Mitnahme des Stößels und Aussteuern des Sperrgliedes.It is advantageous that the additional lock is designed as a magnetic lock which has this plunger protruding from the rear. If the corresponding magnetic key is assigned to the magnetic lock, it can be shifted inward against the load of a compression spring combined with simultaneous entrainment of the plunger and actuation of the locking member.

Der in den Zeichnungen veranschaulichte Beschlag 1 besitzt eine im Grundriss langgestreckte, rechteckige Grundplatte 2. Im oberen Bereich trägt diese eine Handhabe 3. Der untere Bereich 4 der Grundplatte 2 ist stufenförmig abgesetzt und nimmt dort einen in Längsrichtung der Grundplatte 2 geführten Schiebedeckel 5 auf. Dessen sich über eine kurze Länge des Beschlages erstreckende Frontfläche 6 schließt bündig mit der Vorderfläche 7 der Grundplatte 2 ab. Der Querschnitt des Schiebedeckels 5 ist so gewählt, daß die Seitenwände 8 des Schiebedeckels 5 stufenlos in die Seitenflächen 9 der Grundplatte 2 übergehen unter Verwirklichung eines übergangsfreien Erscheinungsbildes. Im wesentlichen besitzt der Beschlag 1 sowohl im Längs- als auch im Querschnitt eine trapezförmige Form.The fitting 1 illustrated in the drawings has an elongated, rectangular base plate 2 in plan. In the upper region, this carries a handle 3. The lower region 4 of the base plate 2 is stepped and takes up a sliding cover 5 guided in the longitudinal direction of the base plate 2. Its front surface 6, which extends over a short length of the fitting, is flush with the front surface 7 of the base plate 2. The cross section of the sliding cover 5 is selected so that the side walls 8 of the sliding cover 5 continuously merge into the side surfaces 9 of the base plate 2 with the realization of a transition-free appearance. The fitting 1 essentially has a trapezoidal shape both in the longitudinal and in the cross section.

Im unteren Bereich wird die Frontfläche 6 des Schiebedeckels 5 von einer Materialverdickung 10 überragt, deren Seitenwände 10' in die Seitenwände 8 übergehen. In den Seitenwänden 8 sind über die gesamte Länge des Schiebedeckels 5 Führungsnuten 11 ausgespart, in welche seitlich vorstehende Führungsstege 12 des unteren Bereiches 4 der Grundplatte 2 eintauchen. Auf diese Weise ist es möglich, den Schiebedeckel 5 in Längsrichtung zur Grundplatte 2 zu verlagern und bis zur Trennstelle T zwischen Grundplatte 2 und Schiebedeckel 5 zu bewegen.In the lower area, the front surface 6 of the sliding cover 5 is surmounted by a material thickening 10, the side walls 10 'of which merge into the side walls 8. In the side walls 8 5 guide grooves 11 are recessed over the entire length of the sliding cover, into which laterally projecting guide webs 12 of the lower region 4 of the base plate 2 are immersed. In this way, it is possible to shift the sliding cover 5 in the longitudinal direction to the base plate 2 and to move it to the separation point T between the base plate 2 and the sliding cover 5.

Die durch die Führungsnuten 11 zurückversetzt liegende Unterseite 13 des Schiebedeckels 5 enthält eine sich bis zur oberen Stirnkante 14 des Schiebedeckels erstreckende Aussparung 15. Letztere ist in ihrer Breite größer als das in sie ragende Ende 16 eines Schließzylinders 17. Bezüglich desselben handelt es sich um einen eine Aufnahmeöffnung 18 des unteren Bereiches 4 der Grundplatte 2 durchsetzenden Profilzylinder. Befindet sich der Schiebedeckel 5 in seiner Verschlußlage, so überfängt er den Schließzylinder 17 und läßt nicht das Einstecken des zum Schließzylinder 17 zugehörigen Schlüssels zu.The underside 13 of the sliding cover 5, which is set back by the guide grooves 11, contains a recess 15 which extends up to the upper end edge 14 of the sliding cover. The width of the recess 15 is greater than that of the end 16 of a locking cylinder 17 which projects into it a receiving opening 18 of the lower region 4 of the base plate 2 passing through profile cylinder. If the sliding cover 5 is in its closed position, it overlaps the locking cylinder 17 and does not permit the key associated with the locking cylinder 17 to be inserted.

Im unteren Bereich 4 der Grundplatte 2 ist auf einer jenseits seiner Längsmittellinie liegenden Seite eine stufenförmig abgesetzte Ausnehmung 19 vorgesehen. Letztere setzt sich aus einem querschnittsgrößeren, der Anschlagfläche des Beschlages zugekehrten Abschnitt 19' und einem querschnittskleineren, der Unterseite 13 des Schiebedeckels zugewendeten Abschnitt 19' zusammen. Die Länge des Abschnittes 19' entspricht dabei einem mehrfachen der Länge des Abschnittes 19". Durch die beiden Abschnitte wird eine Stufe 19 gebildet.In the lower region 4 of the base plate 2, a step-like recess 19 is provided on a side lying beyond its longitudinal center line. The latter is composed of a section 19 'of larger cross section facing the stop face of the fitting and a section 19' of smaller section facing the underside 13 of the sliding cover. The length of section 19 ′ corresponds to a multiple of the length of section 19 ″. A step 19 is formed by the two sections.

In der Ausnehmung 19 ist ein Riegelglied 20 geführt. Letzteres ist als ein mit einem dem querschnittskleineren Sperrende 21 gegenüberliegenden Ringkragen 22 versehener Schließzapfen ausgebildet, der in Vortrittsstellung von einer Druckfeder 23 belastet ist. Die Druckfeder 23 stützt sich zum einen an dem ringkragenseitigen Stirnende des Riegelgliedes 20 und zum anderen an einem in den Abschnitt 19' der Ausnehmung 19 eingeschraubten Gewindeverschlußstopfen 24 ab. Zufolge der Federbelastung liegt der Ringkragen 22 des Riegelgliedes 20 in Vortrittsstellung an der Stufe 19" der Ausnehmung 19 an derart, daß das Sperrende 21 den unteren Bereich der Grundplatte 2 überragt und in eine von der Unterseite 13 des Schiebedeckels 5 ausgehende Sperröffnung 25 eingreift. Vom Boden 25' derselben geht ein quer zur Anschlagebene des Beschlages gerichteter Kanal 26 aus. In diesem ist ein als Stößel gestaltetes Freigabeglied 27 geführt. Endseitig bildet letzteres einen mit einem Querschlitz versehenen verdickten Kopf 28 aus, welcher gegenüber dem Kanal 26 querschnittsgrößer ist und in der Sperröffnung 25 einliegt. Der verdickte Kopf 28 reicht bis zum Sperrende 21 des Riegelgliedes 20. Das dem Kopf 28 gegenüberliegende Schaftende 29 des stößelartigen Freigabegliedes 27 ist in das Gehäuse 30 eines als Magnetschloß 31 ausgebildeten Zusatzschlosses eingeschraubt.A locking member 20 is guided in the recess 19. The latter is designed as a locking pin which is provided with an annular collar 22 opposite the smaller cross-section locking end 21 and which is loaded in the forward position by a compression spring 23. The compression spring 23 is supported on the one hand on the end face of the locking member 20 on the ring collar side and on the other hand on a threaded plug 24 screwed into the section 19 'of the recess 19. Due to the spring loading, the annular collar 22 of the locking member 20 is in the forward position at the step 19 "of the recess 19 in such a way that the locking end 21 projects beyond the lower region of the base plate 2 and engages in a locking opening 25 extending from the underside 13 of the sliding cover 5 Bottom 25 'of this extends from a channel 26 directed transversely to the stop plane of the fitting, in which a release member 27 designed as a tappet is guided, the end of which forms a thickened head 28 provided with a transverse slot, which is larger in cross section than channel 26 and in which Locking opening 25. The thickened head 28 extends to the locking end 21 of the locking member 20. The shaft end 29 of the plunger-like release member 27 opposite the head 28 is screwed into the housing 30 of an additional lock designed as a magnetic lock 31.

Das Magnetschloß 31 besitzt einen kreisförmigen Querschnitt und ist in eine querschnittsangepasste topfförmige Vertiefung 32 der Materialverdickung 10 des Schiebedeckels 5 eingesetzt derart, daß es in seiner Sperrstellung mit der korrespondierenden Vorderfläche 10" der Materialverdickung 10 abschließt, vergleiche Fig. 5.The magnetic lock 31 has a circular shape Cross-section and is inserted into a cup-shaped recess 32 of the material thickening 10 of the sliding cover 5, such that in its locked position it closes with the corresponding front surface 10 "of the material thickening 10, see FIG. 5.

Eine kegelförmig gestaltete Druckfeder 33 belastet das Magnetschloß-Gehäuse 30 in Auswärtsrichtung. Diese Druckfeder 33 stützt sich mit ihrer durchmessergrößeren Windung an dem Boden 32' der topfförmigen Vertiefung 32 ab, während die durchmesserkleinere Windung die zugekehrte Stirnfläche des Gehäuses 30 beaufschlagt. Zusätzlich ist das Gehäuse 30 von einem zentral zur Vertiefung 32 angeordnetenZapfen 34 geführt. Letzterer durchgreift die Druckfeder 33 und ist mittels einer Schraube 35 am Schiebedeckel 5 festgelegt.A conical compression spring 33 loads the magnetic lock housing 30 in the outward direction. This compression spring 33 is supported with its larger diameter turn on the bottom 32 'of the cup-shaped recess 32, while the smaller diameter turn acts on the facing end face of the housing 30. In addition, the housing 30 is guided by a pin 34 arranged centrally to the recess 32. The latter passes through the compression spring 33 and is fixed on the sliding cover 5 by means of a screw 35.

An seinem der Vorderfläche 10" zugekehrten Ende besitzt das Magnetschloß 31 eine Einlagerungsmulde 36 für einen Magnetschlüssel 37. An seinem oberen Ende ist an der Schiebedekkel-Unterseite 13 ein den Öffungsweg des Schiebedeckels begrenzender, mit dem Riegelglied 20 zusammenwirkender Anschlag 38 vorgesehen. Letzterer erstreckt sich rechtwinklig zur Verschiebeebene. Zwischen dem Anschlag 38 und der Sperröffnung 25 befindet sich eine vom Anschlag 38 ausgehende in Richtung der Sperröffnung 25 bis auf Unterseitenniveau ansteigende Auflaufschräge 39, mit welcher das Riegelglied 20 zusammenarbeitet.At its end facing the front surface 10 ″, the magnetic lock 31 has an embedment recess 36 for a magnetic key 37. At its upper end, a stop 38, which interacts with the locking member 20 and interacts with the locking member 20, is provided on the underside of the sliding cover 13. The latter extends Between the stop 38 and the locking opening 25 there is a run-up slope 39 starting from the stop 38 in the direction of the locking opening 25 and rising to the underside level, with which the locking member 20 cooperates.

Auf gleicher Querschnittsebene zum Riegelglied 20 trägt die Grundplatte 2 eine Kugelrast 40. Letztere setzt sich aus einer Druckfeder 41 und einer Kugel 42 zusammen. Beide sind in einer in die Grundplatte 4 eingesetzten Hülse 43 untergebracht und werden durch eine Schraube 44 gehalten. Das der Unterseite 13 zugekehrte Hülsenende ist leicht zugestemmt, so daß die Kugel 42 nicht die Hülse verlassen kann, jedoch gegen die Unterseite 13 drückt und den Schiebedeckel 5 reibungsschlüssig hält. Eine Verschiebung des Deckels 5 muß daher stets willensbetont erfolgen.At the same cross-sectional plane to the locking member 20, the base plate 2 carries a ball catch 40. The latter is composed of a compression spring 41 and a ball 42. Both are accommodated in a sleeve 43 inserted into the base plate 4 and are held by a screw 44. The bottom of the sleeve 13 facing is slightly caulked so that the ball 42 can not leave the sleeve, but presses against the underside 13 and holds the sliding cover 5 frictionally. A shift of the cover 5 must therefore always be deliberate.

Es ergibt sich folgende Wirkungsweise:

  • Gemäß der Verschlußlage des Schiebedeckels 5, vergleiche insbesondere Figur 1 und 5, greift das Riegelglied 20 der Grundplatte 4 in die Sperröffnung 25 des Schiebedeckels 5 ein. Letzterer ist somit gegen Verschieben in Abwärtsrichtung blockiert. Der Schließzylinder 17 ist also nicht betätigbar. Um diesen schließen zu können, muß vorerst der Schiebedeckel in seine Offenstellung verlagert werden. Dies verlangt den erforderlichen Magnetschlüssel 37, der in die Einlagerungsmulde 36 einzulegen ist. Dadurch werden die nicht veranschaulichten Magnete so ausgerichtet, daß anschließend das Magnetschloß 31 entgegen der Kraft der kegelförmigen Druckfeder 33 in Einwärtsrichtung verschoben werden kann. Einhergehend beaufschlagt das Freigabeglied 27 mit seinem Kopf 28 das Riegelglied 20 und bringt dieses in die Rücktrittsstellung gemäß Figur 6. Die Querverlagerung des Magnetschlosses 31 ist beendet, wenn die endseitige Stirnfläche des Kopfes 28 des Freigabegliedes auf Höhe der Unterseite 13 des Schiebedeckels 5 liegt.
This works as follows:
  • According to the closed position of the sliding cover 5, compare in particular FIGS. 1 and 5, the locking member 20 of the base plate 4 engages in the locking opening 25 of the sliding cover 5. The latter is thus blocked against moving downwards. The lock cylinder 17 can therefore not be actuated. In order to be able to close this, the sliding cover must first be moved into its open position. This requires the required magnetic key 37, which is to be inserted into the storage recess 36. As a result, the magnets, which are not illustrated, are aligned in such a way that the magnetic lock 31 can then be displaced in the inward direction against the force of the conical compression spring 33. At the same time, the release member 27 acts with its head 28 on the locking member 20 and brings it into the withdrawal position according to FIG. 6. The transverse displacement of the magnetic lock 31 is ended when the end face of the head 28 of the release member lies at the level of the underside 13 of the sliding cover 5.

Nun ist es möglich, den Schiebedeckel 5 in Abwärtsrichtung zu verschieben, wobei das Riegelglied 20 mit seinem Sperrende 21 auf der Auflaufschräge 39 gleitet. Begrenzt ist der Öffnungsweg dadurch, daß der Anschlag 38 gegen das Sperrende 21 des Riegelgliedes 20 stößt, vergleiche Figur 9 und 11. Das Ende 16 des Schließzylinders 17 liegt nun zur Schlüsselbetätigung frei. Nach der Verlagerung des Schiebedeckels 5 oder während dieser kann der Magnetschlüssel abgenommen werden. Die Druckfeder 43 bringt dann das Magnetschloß wieder in seine Ausgangsstellung verbunden mit einem Zurückziehen des Freigabegliedes 27.It is now possible to move the sliding cover 5 in the downward direction, the locking member 20 sliding with its locking end 21 on the run-up slope 39. The opening path is limited by the fact that the stop 38 abuts the locking end 21 of the locking member 20, see FIGS. 9 and 11. The end 16 of the locking cylinder 17 is now exposed for key actuation. After the sliding cover 5 has been moved or during this, the magnetic key can be removed. The compression spring 43 then brings the magnetic lock back into its starting position connected with a withdrawal of the release member 27.

Soll die Sperrlage des Schiebedeckels 5 wieder herbeigeführt werden, so braucht letzterer nur in Aufwärtsrichtung geschoben zu werden. Das federbelastete Riegelglied 20 wird über die Auflaufschräge 39 bis auf das Unterseitenniveau des Schiebedeckels gebracht, so daß in der Endphase der Verschlußbewegung das federbeaufschlagte Sperrglied 20 mit seinem Sperrende 21 in die Sperröffnung 25 eintauchen kann unter Blockierung einer Bewegung des Schiebedeckels 5.If the locking position of the sliding cover 5 is to be brought back again, the latter need only be pushed in the upward direction. The spring-loaded locking member 20 is brought over the bevel 39 to the underside level of the sliding cover, so that in the final phase of the closing movement, the spring-loaded locking member 20 can dip into the locking opening 25 with its locking end 21, blocking movement of the sliding cover 5.
