Description
Der Gegenstand vorliegender Erfindung bezieht sich auf ein von außen mittels Schlüssels und von innen durch Hand zu öffnendes Sicherheitskettenschloß.The subject matter of the present invention relates to an externally by means of a key and a safety chain lock that can be opened by hand from the inside.
Von bekannten Vorrichtungen dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß als Kettenspannvorrichtung ein Schlitzhebel dient, der gehäuseartig ausgebildet, drehbar an der Schloßgrundplatte angeordnet ist und in einer in ihm vorgesehenen Buchse zwei· gegenüberliegende Nuten besitzt, in die in der Schließlage je zwei durch eine Schraubenfeder auseinandergehaltene Sicherungsplatten des Schlosses eingreifen. In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigtThe subject of the invention differs from known devices of this type in that a slotted lever is used as the chain tensioning device, which is designed in the manner of a housing, is rotatably arranged on the lock base plate and provided in it Bushing has two opposing grooves, in each of which two through in the closed position Engage a coil spring held apart locking plates of the lock. In the drawing, the subject of the invention is shown, namely shows

Fig. 4 dias Schloß mit eingeführtem Schlüssel in entsichertem Zustand und im as Schnitt nach der Linie A-B der Fig. 3.FIG. 4 shows the lock with the key inserted in the unlocked state and in a section along the line AB in FIG. 3.
Das Schloß besteht aus der Schloßgrundplatte a, auf der die Deckplatte b befestigt ist und hierbei den Hebel c drehbar hält. Die Buchse d ist mit dem Hebel c fest verbunden und hat an zwei gegenüberliegenden Stellen Nuten n, in die die Sicherungsplatten e eingreifen. Die Buchse f ist auch auf der Schloßgrundplatte α befestigt und hat dieselben Nuten wie die Buchse d, in denen die Sicherungsplatten β geführt werden. Die Hülse g dient zur Führung des Schlüssels h, der am vorderen Ende mit Rasten versehen ist, die beliebig tief gemacht werden können, um jedem Schlüssel eine andere Form zu geben. Beim Einführen des Schlüsselst in das Schloß zieht der Schlüssel h die Sicherungsplatten e aus der Buchse d, und der Hebel c ist entsichert. Der Mitnehmer i ist mit der Buchse d und somit auch mit dem Hebel c fest verbunden. Soll die Sicherheitskette von innen benutzt werden, drückt man, nachdem die Kette bei χ eingehängt ist (Fig. 1), auf die zwei Druckstücke k und dreht den Hebel c um i8o°, bis er an den Anschlagstift I anschlägt, hiermit ist die Kette gespannt (Fig. 2). In dieser Schließlage drücken die Federn m die Sicherungsplatten e in die Nuten- η der Buchse d, und der Hebel c des Schlosses ist gegen Drehung gesichert. Wird die Kette von außen eingehängt, so wird mit dem Schlüssel h der Hebel c um i8o° gedreht, bis er an den Anschlagstift I anschlägt und hiermit die Kette anspannt. Beim Herausziehen des Schlüssels h drücken die Federn m die Sicherungsplatten e in die Nuten 11 der Buchse d, und der Hebel c ist gegen Drehung gesichert.The lock consists of the lock base plate a, on which the cover plate b is attached and hereby holds the lever c rotatably. The socket d is firmly connected to the lever c and has grooves n at two opposite points into which the locking plates e engage. The socket f is also attached to the lock base plate α and has the same grooves as the socket d, in which the locking plates β are guided. The sleeve g is used to guide the key h, which is provided at the front end with notches that can be made as deep as you want to give each key a different shape. When the key is inserted into the lock, the key h pulls the locking plates e out of the socket d and the lever c is unlocked. The driver i is firmly connected to the socket d and thus also to the lever c. If the safety chain is to be used from the inside, after the chain is attached to χ (Fig. 1), press on the two pressure pieces k and turn lever c by 180 ° until it hits the stop pin I , this is the chain tensioned (Fig. 2). In this closed position, the springs m press the locking plates e into the grooves η of the socket d, and the lever c of the lock is secured against rotation. If the chain is attached from the outside, the key h is used to turn the lever c by 180 ° until it strikes the stop pin I and thereby tightens the chain. When the key h is withdrawn, the springs m press the locking plates e into the grooves 11 of the socket d, and the lever c is secured against rotation.
Das Schloß wird wie die anderen Sicherheitsschlösser an den Türen befestigt und die Kette am Türrahmen, wobei auch die einfachen Sicherkeitsketten benutzt werden könThe lock is attached to the doors like the other security locks and the Chain on the door frame, whereby the simple safety chains can also be used
