Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Doppelbartschloß mit einem kastenförmigen Gehäuse, einer Schloßdecke, einem in diesem Gehäuse gelagerten Riegel mit Tourstift und einem auf dem Riegel liegenden Zuhaltungspaket.The invention relates to a double bit lock with a box-shaped Housing, a castle ceiling, a bolt stored in this housing with tour pen and a tumbler package lying on the bolt.

Stand der TechnikState of the art

Es ist üblich, daß das Schloßgehäuse vier Stützhülsen aufweist, die Schrauben aufnehmen und der Befestigung des Schlosses auf der Schranktür dienen. Weiterhin ist es bekannt, die Schloßdecke nach der Montage der Schloßbestandteile mit Schrauben am Schloßgehäuse zu befestigen.
Andererseits ist es bei Billigschlössern oder Blechspielzeugen bekannt, mehrere Teile mit Hilfe verschränkter oder umgeklappter Blechlappen zu verbinden.
Das Herstellen von Gewindelöchern und das Verschrauben der Teile ist teuer.It is common for the lock housing to have four support sleeves that receive the screws and are used to attach the lock to the cabinet door. Furthermore, it is known to fasten the lock cover to the lock housing with screws after the assembly of the lock components.
On the other hand, it is known for cheap locks or tin toys to connect several parts with the help of folded or folded sheet metal tabs.
Making threaded holes and screwing the parts together is expensive.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ohne Verlust an Stabilität die Montagekosten zu verringern.
Dies gelingt erfindungsgemäß dadurch, daß die Schloßdecke an der vorderen Stirnseite Vorsprünge aufweist, die in Öffnungen an der Stirnwand des Gehäuses passen, daß die Schloßdecke an der hinteren Stirnseite Aussparungen aufweist, die in Montageposition hinter angeformte Gehäusevorsprünge greifen und daß die Schloßdecke an der hinteren Stirnseite eine Zunge aufweist, die nach der Montage eine plastische Verformung erfährt, um die Schloßdecke gegen Verschiebung in die Demontageposition zu sichern.The invention has for its object to reduce the assembly costs without loss of stability.
This is achieved according to the invention in that the lock cover has projections on the front end that fit into openings on the end wall of the housing, that the lock cover has recesses on the rear end that engage behind molded housing projections in the mounting position and that the lock cover on the rear end has a tongue, which undergoes plastic deformation after assembly in order to secure the lock cover against displacement into the disassembly position.

In Fig. 1 und 2 ist mit 1 ein im Druckgußverfahren hergestelltes Gehäuse bezeichnet, dessen umlaufender Rand abgerundet wird. An der vorderen Stirnseite 1a tritt der Riegel 2 aus. In das Gehäuse 1 sind vier Stützhülsen 1b, 1c, 1d, le eingeformt, die Schrauben zur Befestigung des Schlosses aufnehmen. Die Hülsen 1b und 1c tragen Nasen 1b1 und 1c1, auf denen eine Schloßdecke 3 aufliegt. Diese Schloßdecke weist an ihrer vorderen Stirnseite 3a zwei Vorsprünge 3a1 und 3a2 auf, die in öffnungen 1a1 und 1a2 des Gehäuses passen. An der hinteren Stirnseite 3b ist eine Zunge 3b1 angeformt, der zwei längere Vorsprünge 3b2 und 3b3 benachbart sind. Die Teile 3b1, 3b2 und 3b3 liegen auf einer Aussparung 1f1 der hinteren Gehäusestirnwand 1f auf.
An die Stützhülsen 1d, 1e sind Vorsprünge 1d1 und 1e1 angeformt, die über der Ebene der Schloßdecke 3 liegen.
Die Schloßdecke 3 ist in der Umgebung der Stützhülsen 1d, 1e mit Aussparungen 3c, 3d versehen, die eine begrenzte Verschiebung nach links erlauben. Dabei schieben sich die Kanten dieser Aussparungen 3c, 3d unter die Vorsprünge 1d1 und 1e1, wie es Fig. 3 und 4 zeigt. Mit 3e ist das Schlüsselloch bezeichnet. Wenn jetzt noch die Zunge 3b1 plastisch verformt, also nach unten gedrückt wird, ist die Schloßdecke 3 ohne jede Schraube dauerhaft befestigt
In Fig. 3 ist das Schloßgehäuse mit der eingeschobenen Schloßdecke dargestellt. Man erkennt dies daran, daß die Vorsprünge 3b2, 3b3 im Gegensatz zu Fig. 1 mit dem rechten Gehäuserand abschließen.
Fig. 4 zeigt im Schnitt die nach links verschobene und damit gegen Abheben gesicherte Decke 3.
Aus Fig. 5 ist ersichtlich, wie die Decke 3 durch Verformung der Zunge 3b1 gegen Verschiebung gesichert ist.
Wenn das Schloß demontiert werden soll, biegt man mit einem Werkzeug die Zunge 3b1 gerade. Danach kann die Schloßdecke 3 nach rechts geschoben und nach oben abgehoben werden.1 and 2, 1 designates a housing produced by die casting, the peripheral edge of which is rounded. The bolt 2 emerges from the front end face 1a. Four support sleeves 1b, 1c, 1d, le are molded into the housing 1 and hold the screws for fastening the lock. The sleeves 1b and 1c carry lugs 1b1 and 1c1, on which a lock cover 3 rests. This lock cover has on its front face 3a two projections 3a1 and 3a2 which fit into openings 1a1 and 1a2 of the housing. A tongue 3b1 is formed on the rear end face 3b, and two longer projections 3b2 and 3b3 are adjacent to it. The parts 3b1, 3b2 and 3b3 rest on a recess 1f1 in the rear housing end wall 1f.
Protrusions 1d1 and 1e1 are formed on the support sleeves 1d, 1e and lie above the plane of the castle ceiling 3.
The lock cover 3 is provided in the vicinity of the support sleeves 1d, 1e with recesses 3c, 3d, which allow a limited displacement to the left. The edges of these recesses 3c, 3d slide under the projections 1d1 and 1e1, as shown in FIGS. 3 and 4. The keyhole is designated 3e. If the tongue 3b1 is now plastically deformed, i.e. pressed down, the lock cover 3 is permanently attached without any screw
In Fig. 3 the lock housing is shown with the lock cover inserted. This can be seen from the fact that, in contrast to FIG. 1, the projections 3b2, 3b3 terminate with the right edge of the housing.
4 shows in section the ceiling 3 which is shifted to the left and thus secured against lifting off.
From Fig. 5 it can be seen how the ceiling 3 is secured against displacement by deformation of the tongue 3b1.
If the lock is to be dismantled, the tongue 3b1 is bent straight with a tool. The lock cover 3 can then be pushed to the right and lifted off.

Gewerbliche VerwertbarkeitCommercial usability

Die beschriebene Konstruktion hat den großen Vorteil, daß Bauelemente und Arbeitsgänge eingespart werden, wobei zusätzlich die Montagezeit für die Decke erheblich verkürzt ist. The construction described has the great advantage that components and operations are saved, with additional the installation time for the ceiling is significantly reduced.
