Description

Die Erfindung betrifft eine Schutzkappe für ein einen Schlosskasten aufweisendes Schloss einer Tür, mit zwei den Schlosskasten seitlich überdeckenden Seitenwandungen und mit einem die Seitenwandungen verbindenden Steg, wobei der Steg in zumindest einem Teilbereich als Verstärkungssteg ausgebildet ist und der Verstärkungssteg eine höhere Festigkeit aufweist als die Seitenwandungen.The invention relates to a protective cap for a lock of a door having a lock case, with two side walls that laterally cover the lock case and with a web connecting the side walls, the web being designed in at least a partial area as a reinforcing web and the reinforcing web having a higher strength than the side walls .

Aus der GB 2 369 856 A ist ein Verankerungselement für ein Schloss bekannt geworden, welches mit einem Gehäuse verbunden ist. Das Gehäuse ist im montierten Zustand über das Schloss geschoben. Das Verankerungselement stützt das Schloss in der Tür ab. Hierdurch ist das Verankerungselement mit dem Gehäuse sehr aufwändig aufgebaut.From the GB 2 369 856 A An anchoring element for a lock has become known, which is connected to a housing. When assembled, the housing is pushed over the lock. The anchoring element supports the lock in the door. As a result, the anchoring element with the housing is constructed in a very complex manner.

Aus der DE 696 06 740 T2 ist ein Gehäuse für ein Einbauschloss bekannt geworden. Das Gehäuse hat eine Montagebasis und einen mit der Montagebasis verbundenen Deckel. Von der Montagebasis steht eine Lasche ab, welche mit einem Rand des Deckels verschraubt ist.From the DE 696 06 740 T2 A housing for a built-in lock has become known. The housing has a mounting base and a lid connected to the mounting base. A tab protrudes from the mounting base and is screwed to one edge of the lid.

Die EP 1 260 657 A1 offenbart ein Schlossgehäuse mit Seitenwandungen. Die Seitenwandungen sind über Stifte miteinander verbunden.The EP 1 260 657 A1 reveals a lock housing with side walls. The side walls are connected to each other via pins.

Eine Schutzkappe ist beispielsweise aus der DE 83 27 932 U1 bekannt. Die Schutzkappe ist als quaderförmige, ein Schlossgehäuse überdeckende Schutzhaube ausgebildet und hat Streifen zur Befestigung an einer Tür. Die Schutzkappe ist aus Stahlblech gefertigt und hat damit an jeder Stelle die gleiche Stabilität. Durch die vollständige Überdeckung des Schlossgehäuses ist die Schutzkappe jedoch sehr aufwändig aufgebaut.A protective cap is, for example, from the DE 83 27 932 U1 known. The protective cap is designed as a cuboid protective hood that covers a lock housing and has strips for attachment to a door. The protective cap is made of sheet steel and therefore has the same stability at every point. However, because the lock housing is completely covered, the protective cap is very complex to construct.

Aus der EP 2 339 095 A2 ist eine Schlosskastensicherung bekannt geworden, bei der eine Basisplatte mehrere Haltezapfen hat und auf der Rückseite des Schlosskastens angeordnet ist. Diese Schlosskastensicherung erhöht eine Einbruchssicherheit bei dem Einsatz des Schlosses in einem Hohlprofilrahmen. Für den Einsatz dieser Schlosskastensicherung muss eine Ausnehmung für das Schloss von zwei Seiten her zugänglich sein.From the EP 2 339 095 A2 A lock case security device has become known in which a base plate has several retaining pins and is arranged on the back of the lock case. This lock case security increases burglary security when the lock is used in a hollow profile frame. To use this lock case security, a recess for the lock must be accessible from two sides.

Der Erfindung liegt das Problem zugrunde, eine Schutzkappe der eingangs genannten Art so weiter zu bilden, dass sie kostengünstig herstellbar ist und einen hohen Schutz für nahezu beliebige Schlösser bietet.The invention is based on the problem of developing a protective cap of the type mentioned in such a way that it can be produced inexpensively and offers a high level of protection for almost any lock.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass sich der Steg über die gesamte Höhe der Seitenwandungen erstreckt und eine einzelne Ausnehmung zur Durchführung einer Schließzylinderschraube aufweist.This problem is solved according to the invention in that the web extends over the entire height of the side walls and has a single recess for the passage of a locking cylinder screw.

Durch diese Gestaltung weist die Schutzkappe an einer besonders kritischen Stelle mit dem Verstärkungssteg eine Verstärkung zur Erhöhung der Stabilität in einem für Manipulationen gefährdeten Bereich auf. Der Verstärkungssteg überdeckt hierdurch eine meist offene Schmalseite des Schlosses und verhindert, dass mit einem Werkzeug in ein Getriebe zwischen einem Schließzylinder und einem Riegel eingegriffen wird. Hierdurch hat der von dem Verstärkungssteg abgedeckte Bereich des Schlosskastens einen hohen Schutz vor Manipulation. Daher können die Seitenwandungen, welche den ohnehin stabilen Schlosskasten seitlich überdecken, aus sehr dünnwandigem Material gefertigt sein. Damit lässt sich ein nahezu beliebig gestaltetes Schloss zusammen mit der Schutzkappe in eine sehr enge Tasche der Tür einschieben. Dank der Erfindung ist die Schutzkappe besonders kostengünstig herstellbar. Die Schutzkappe lässt sich besonders kostengünstig durch Abwinklungen eines ausgestanzten Blechs fertigen, weil sich der Steg über die gesamte Höhe der Seitenwandungen erstreckt und eine einzelne Ausnehmung zur Durchführung einer Schließzylinderschraube aufweist.As a result of this design, the protective cap has a reinforcement at a particularly critical point with the reinforcing web to increase stability in an area at risk of manipulation. The reinforcing web thereby covers a mostly open narrow side of the lock and prevents a tool from interfering with a gear between a lock cylinder and a bolt. As a result, the area of the lock case covered by the reinforcing web has a high level of protection against manipulation. Therefore, the side walls, which laterally cover the already stable lock case, can be made of very thin-walled material. This means that a lock of almost any design can be inserted together with the protective cap into a very narrow pocket in the door. Thanks to the invention, the protective cap can be produced particularly cost-effectively. The protective cap can be manufactured particularly cost-effectively by bending a punched-out sheet metal because the web extends over the entire height of the side walls and has a single recess for the passage of a locking cylinder screw.

Der Steg und die Seitenwandungen könnten sich beispielsweise über die gesamte Höhe des Schlosskastens erstrecken. Dies führt jedoch zu hohen Fertigungskosten der Schutzkappe. Ein vollständiges Umschließen des Schlosskastens ist meist nicht erforderlich. Ein ausreichender Schutz vor einer Manipulation eines an den Schließzylinder angrenzenden Getriebes lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei besonders geringem Materialaufwand einfach vermeiden, wenn der Steg und der Verstärkungssteg einen Eckbereich des Schlosskastens überdecken und wenn die Seitenwandungen ungefähr die Hälfte der Höhe des Schlosskastens aufweisen.The web and the side walls could, for example, extend over the entire height of the lock case. However, this leads to high production costs for the protective cap. It is usually not necessary to completely enclose the lock case. According to another advantageous development of the invention, adequate protection against manipulation of a gearbox adjacent to the locking cylinder can be easily avoided with particularly little material expenditure if the web and the reinforcing web cover a corner area of the lock case and if the side walls are approximately half the height of the lock case exhibit.

Eine Ausnehmung in dem Steg ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders sicher, wenn der Steg eine nach außen gerichtete Ausformung zur Durchführung einer Befestigungsschraube in senkrechter Richtung zu den Seitenwandungen aufweist. Dadurch ist die die Schutzkappe zusätzlich sichernde und über den Steg nach außen überstehende Befestigungsschraube von außen unzugänglich gesichert. Eine sonst übliche offene Ausnehmung wird vermieden. Die Befestigungsschraube dient bevorzugt der Befestigung der Innen- und/oder der Außenhandhabe der Tür.According to another advantageous development of the invention, a recess in the web is particularly secure if the web has an outwardly directed shape for the passage of a fastening screw in a perpendicular direction to the side walls having. This means that the fastening screw that additionally secures the protective cap and protrudes beyond the web is secured so that it is inaccessible from the outside. An otherwise usual open recess is avoided. The fastening screw is preferably used to fasten the inside and/or outside handle of the door.

Die Schutzwirkung der Schutzkappe ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders groß, wenn die nach außen gerichtete Ausformung halbrund gestaltet ist und mit einem im Schlosskasten entgegenstehenden halbrunden Einschnitt eine in etwa kreisrunde Durchführung bildet. Die Befestigungsschraube sichert somit zusätzlich das Schloss und die Schutzkappe vor mutwilligem Verschieben. Bei dieser Weiterbildung der Erfindung ist eine entsprechende halbrunde Ausnehmung in den Seitenwandungen vorzusehen. Da der Abstand der Befestigungsschraube zum Schließzylinder häufig sehr gering ist, ist der im Schlosskasten entgegenstehende halbrunde Einschnitt bei einer Vielzahl von Schlossvarianten bereits vorhanden.According to another advantageous development of the invention, the protective effect of the protective cap is particularly great if the outward-facing shape is semicircular and forms an approximately circular passage with a semicircular incision in the lock case. The fastening screw additionally secures the lock and the protective cap against intentional displacement. In this development of the invention, a corresponding semicircular recess must be provided in the side walls. Since the distance between the fastening screw and the lock cylinder is often very small, the semicircular incision in the lock case is already present in a large number of lock variants.

Der Verstärkungssteg lässt sich gemäß einer anderen vorteilhaften Weiter-bildung der Erfindung aus einem nahezu beliebigen Material mit einer vorgesehenen Festigkeit fertigen, wenn der Verstärkungssteg ein Einlageelement mit einer im Vergleich zu den Seitenwandungen erhöhten Festigkeit hat.According to another advantageous development of the invention, the reinforcing web can be made from almost any material with a specified strength if the reinforcing web has an insert element with increased strength compared to the side walls.

Zur weiteren Verringerung der Fertigungskosten der Schutzkappe trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn der Verstärkungssteg zwei durch Abwinklung der Seitenwandungen gebildete Überlappungen aufweist.According to another advantageous development of the invention, it contributes to further reducing the manufacturing costs of the protective cap if the reinforcing web has two overlaps formed by bending the side walls.

Ein Aufbiegen des von Überlappungen gebildeten Verstärkungssteges lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die den Verstärkungssteg bildenden Überlappungen durch Verschweißen, oder Vernieten oder Durchsetzfügen miteinander verbunden sind.According to another advantageous development of the invention, bending of the reinforcing web formed by overlaps can be easily avoided if the overlaps forming the reinforcing web are connected to one another by welding, riveting or clinching.

Die Montage der Schutzkappe gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Seitenwandungen eine Fixiereinrichtung zur Halterung an dem Schlosskasten aufweisen.According to another advantageous development of the invention, the assembly of the protective cap is particularly simple if the side walls have a fixing device for mounting on the lock case.

Die Fixiereinrichtung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die Fixiereinrichtung Rastmittel zur Verrasterung an dem Schlosskasten hat. Durch diese Gestaltung lässt sich die Schutzkappe einfach auf den Schlosskasten aufstecken und mit dem Schloss in der Tür montieren.According to another advantageous development of the invention, the fixing device is structurally particularly simple if the fixing device provides locking means Has a catch on the lock case. This design allows the protective cap to be easily placed on the lock case and mounted with the lock in the door.

Die Rastmittel lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kostengünstig fertigen, wenn die Rastmittel in den Seitenwandungen angeordnete Senkungen aufweisen.According to another advantageous development of the invention, the locking means can be manufactured particularly cost-effectively if the locking means have depressions arranged in the side walls.

Die Schutzkappe weist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kleine Abmessungen auf, wenn die Rastmittel neben Ausnehmungen für einen Schließzylinder angeordnet sind.According to another advantageous development of the invention, the protective cap has particularly small dimensions if the locking means are arranged next to recesses for a locking cylinder.

Die Fixiereinrichtung lässt sich besonders kostengünstig fertigen, wenn die Seitenwandungen aufeinander zulaufend gestaltet sind. Diese Gestaltung ermöglicht eine Klemmverbindung der Schutzkappe mit dem Schlosskasten.The fixing device can be manufactured particularly cost-effectively if the side walls are designed to taper towards one another. This design enables a clamp connection of the protective cap to the lock case.

Dabei können die Seitenwandungen zu dem Steg oder von dem Steg aufeinander zulaufend gestaltet sein.The side walls can be designed to converge towards the web or from the web.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips sind mehrere davon in der Zeichnung dargestellt und werden nachfolgend beschrieben. Diese zeigt in

Fig.3
Another embodiment of the protective cap in a perspective view.

Figur 1 zeigt ein als Treibstangenschloss ausgebildetes Schloss 1 zur An-ordnung in einer Tür. Das Schloss 1 hat einen Schlosskasten 2 mit einem Riegel 3 und einer Falle 4. Der Riegel 3 und die Falle 4 lassen sich von einem Schließzylinder 5 und von einer Nuss 6 aus dem Schlosskasten 2 her-ausfahren oder in diesen zurückziehen. Das Schloss 1 ist im montierten Zustand in einer Tasche der Tür eingesetzt. Figure 1 shows a lock 1 designed as an espagnolette lock for arrangement in a door. The lock 1 has a lock case 2 with a bolt 3 and a latch 4. The bolt 3 and the latch 4 can be moved out of the lock case 2 or retracted into it by a lock cylinder 5 and a nut 6. When assembled, the lock 1 is inserted into a pocket in the door.

Weiterhin hat das Schloss 1 eine Schutzkappe 7, welche einen den Schließzylinder 5 aufweisenden Eckbereich des Schlosskastens 2 überdeckt. In diesem Eckbereich ist in der Regel ein nicht dargestelltes Getriebe zum Antrieb des Riegels 3 über dem Schließzylinder 5 angeordnet.Furthermore, the lock 1 has a protective cap 7, which covers a corner area of the lock case 2 that has the lock cylinder 5. In this corner area, a gear (not shown) for driving the bolt 3 is usually arranged above the lock cylinder 5.

Das Schloss 1 und die Schutzkappe 7 weisen fluchtende und in etwa kreisrunde Durchführungen 19, 21 für nicht dargestellte Befestigungsschrauben auf. Die Durchführungen 19, 21 sind jeweils auf einer entgegengesetzten Seite und im gleichen Abstand und auf einer Achse neben dem Schließzylinder angeordnet. Die Durchführung 21 durchdringt zur Hälfe den Schloss-kasten 2 und zur anderen Hälfte eine Ausformung 20 in einem Steg 10.The lock 1 and the protective cap 7 have aligned and approximately circular bushings 19, 21 for fastening screws, not shown. The bushings 19, 21 are each arranged on an opposite side and at the same distance and on an axis next to the lock cylinder. The implementation 21 Half penetrates the lock case 2 and the other half penetrates a formation 20 in a web 10.

Wie Figur 2 in einer perspektivischen Darstellung zeigt, hat die Schutzkappe 7 zwei Seitenwandungen 8, 9 zur Auflage auf seitlichen Flächen des Schlosskastens 2 und den Steg 10 zur Verbindung der Seitenwandungen 8, 9. Die Ausformung 20 in dem Steg 10 steht halbrund gewölbt nach außen von der Schutzkappe 7 ab. Die Seitenwandungen 8, 9 weisen im Bereich der Ausformung 20 Halbrundausnehmungen auf, die die Öffnungen für die Befestigungsschrauben zur Kreisform vervollständigten. Wie Figur 1 zeigt, überdeckt der Steg 10 im montierten Zustand die dem Riegel 3 abgewandte Seite des Schlosskastens 2. An der Unterseite ist der Steg als Verstärkungssteg 11 ausgebildet. Dieser Verstärkungssteg 11 wird von Überlappungen 12, 13 von Abwinklungen der Seitenwandungen 9 gebildet. Die Überlappungen 12, 13 sind mittels einer Punktschweißung 14 miteinander verschweißt. In den Seitenwandungen 8, 9 ist eine Fixiereinrichtung 15 mit Rastmitteln 16 zur Verrastung mit dem Schlosskasten 2 aus Figur 1 angeordnet. Diese Rastmittel 16 sind als in den Seitenwandungen 8, 9 angeordnete Senkungen ausgebildet. Damit lässt sich die Schutzkappe 7 mit dem Schlosskasten 2 verrasten und in der Tür montieren. Die Rastmittel 16 sind neben Ausnehmungen 17 für den Schließzylinder 5 aus Figur 1 angeordnet. Der Steg 10 ist mit Ausnahme einer Ausnehmung 18 zur Durchführung einer Schließzylinderschraube des Schließzylinders 5 aus Figur 1 vollständig geschlossen und erstreckt sich über die gesamte Höhe der Seitenwandungen 8, 9.How Figure 2 shows in a perspective view, the protective cap 7 has two side walls 8, 9 for resting on side surfaces of the lock case 2 and the web 10 for connecting the side walls 8, 9. The formation 20 in the web 10 is semicircularly curved outwards from the protective cap 7 off. The side walls 8, 9 have 20 semicircular recesses in the area of the shape, which complete the openings for the fastening screws to form a circular shape. How Figure 1 shows, the web 10 in the assembled state covers the side of the lock case 2 facing away from the bolt 3. On the underside, the web is designed as a reinforcing web 11. This reinforcing web 11 is formed by overlaps 12, 13 of bends in the side walls 9. The overlaps 12, 13 are welded together by means of a spot weld 14. In the side walls 8, 9 there is a fixing device 15 with locking means 16 for locking with the lock case 2 Figure 1 arranged. These locking means 16 are designed as depressions arranged in the side walls 8, 9. This allows the protective cap 7 to be locked with the lock case 2 and mounted in the door. The locking means 16 are next to recesses 17 for the lock cylinder 5 Figure 1 arranged. The web 10 is designed, with the exception of a recess 18, for the passage of a locking cylinder screw of the locking cylinder 5 Figure 1 completely closed and extends over the entire height of the side walls 8, 9.

Figur 3 zeigt eine weitere Ausführungsform einer Schutzkappe 117, welche sich von der aus Figur 2 dadurch unterscheidet, dass ein Verstärkungssteg 111 in die Seitenwandungen 108, 109 eingeschweißt ist. Der Verstärkungs-steg 111 hat eine höhere Festigkeit als die Seitenwandungen 108, 109. Weiterhin sind die Seitenwandungen 108, 109 von einem Steg 110 aus gesehen aufeinander zulaufend gestaltet. Damit bilden die aufeinander zulaufenden Seitenwandungen 108, 109 eine Fixiereinrichtung 115 zur Vormontage auf dem Schlosskasten 2 aus Figur 1. Figure 3 shows a further embodiment of a protective cap 117, which is from Figure 2 differs in that a reinforcing web 111 is welded into the side walls 108, 109. The reinforcing web 111 has a higher strength than the side walls 108, 109. Furthermore, the side walls 108, 109 are designed to converge towards one another when viewed from a web 110. The converging side walls 108, 109 thus form a fixing device 115 for pre-assembly on the lock case 2 Figure 1 .
