Description

Der Gegenstand der Erfindung ist eine KIinkenrolladensicherung gegen unbefugtes Hochheben des Rolladens von außen her.The subject of the invention is a locking roller shutter protection against unauthorized persons Lifting the roller shutter from the outside.

Sicherungen dieser Art sind bekannt, und zwar hat man Bereits oberhalb des Rolladens unter Federdruck stehende Sperrbolzen angeordnet, die nach Schließen des Rolladens nach vorn gegen die Rolladenwand gedrückt werden. Derartige Sicherungen können wohlFuses of this type are known, and that one already has above the roller shutter spring-loaded locking pin arranged after the shutter is closed be pressed forward against the roller shutter wall. Such backups can

ίο. bei schweren Rolladen ihren Zweck erfüllen, doch versagen dieselben bei leichten Rollladen vollständig, weil der Laden infolge des dauernden Federdruckes am Herabgleiten verhindert wird. Weiterhin besteht bei allen unter Federdruck arbeitenden Sicherungen die Gefahr, daß die Federn rosten oder erlahmen. ίο. fulfill their purpose with heavy shutters, but they fail completely with light roller shutters, because the shutter as a result of the constant spring pressure is prevented from sliding down. Furthermore there is with all Fuses working under spring pressure run the risk of the springs rusting or weakening.

Beim Erfindungsgegenstand soll die Sperrklinke lediglich durch ihr Eigengewicht in die Schließlage gebracht werden. Ausgerückt wird sie durch einen oben am Ende der Führung vorgesehenen Daumen an der Klinke, der in der Bewegungsbähn der Rolladenstäbe liegt, wenn dieselben über eine an sich bekannte Abrundung der oberen Führung hinweggezogen werden.In the subject matter of the invention, the pawl should only be in the closed position are brought. It is released by one at the top of the guide provided thumb on the latch, which is in the movement path of the roller shutter slats, if the same is known per se Rounding off the upper guide.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigenIn the drawing, an embodiment of the invention is shown, namely demonstrate

Zur Sicherung des Rolladens dient eine durch Eigengewicht selbsttätig in die Sperrlage einfallende um den Zapfen α der Platte e schwingende Sperrklinke b, die einen vorderen Daumen c in Höhe des . abgerundeten Rolladeneinlaufes trägt. An dem obersten Rollstab h sitzt eine Platte / mit einem Sperrwinkel g. Gegen letzteren stützt sich beim unbefugten Hochheben des Rolladens die Sperrklinke b und verhindert ein Hochschieben des Rolladens von außen her.To secure the roller shutter is used by its own weight automatically falling into the blocking position around the pin α of the plate e swinging pawl b, which has a front thumb c at the level of the. rounded roller shutter inlet. At the uppermost roll bar h sits a plate / with a locking angle g. The pawl b is supported against the latter when the roller shutter is lifted by unauthorized persons and prevents the roller shutter from being pushed up from the outside.

Beim ordnungsmäßigen Hochziehen des Rolladens verdrängt die Platte f, sobald der oberste Rolladenstab h über den abgerundeten Führungseinlauf hinweggezogen wird, den Daumen c und bewegt denselben mit der Klinke b nach hinten, so daß der Sperrwinkel g unbehindert vorbeigleiten kann.When the roller shutter is properly pulled up, the plate f displaces the thumb c as soon as the top roller shutter rod h is pulled over the rounded guide inlet, and moves the thumb c backwards with the pawl b so that the locking angle g can slide past unhindered.
