DE102017005587A1 - Locking device with self-adjusting number coding - Google Patents

Abstract

The invention relates to a closure device (17) whose handle (2) is released only after entering the correct number coding, wherein when operating the shared handle (2) automatically and forcibly the number coding is adjusted so that the handle (2) after the operation moved back to its original position and that a re-operation of the handle (2) only after setting the correct number coding is possible.

Description

The invention relates to an opening assurance for locking and unlocking of windows and doors according to the preamble of claim 1, which can be used in both the mobile and immobile area. It is described below by way of example installed in a window, but the invention is not limited thereto.

Windows are increasingly designed burglar resistant, that is, it is predominantly locks with mushroom pins used so that at their resistance leverages often fails. So that the burglars still reach their destination, the opening mechanism is increasingly attacked. Thus, among other things, at the level of the window handle, a hole is drilled through the wing and this is brought into the open position with a bent wire. Lockable window handles are designed to prevent this and other attacks. Experience has shown, however, that with daily repeated airing after some time, if nothing has happened, is not completed or the key gets stuck in the lock. In this way, it can be operated either by the "window drilling method" or by wrapping the glass in the handle and opened the window. Another method of attack is that when the handle is unlocked, a mushroom pin is exposed and levered out of the strike plate. All mushroom pins are brought out of the striking plates so that the window can be opened. In addition, every now and then the gear is drilled at the level of the square, the square drilled out and in this way the mushroom pins are pushed out of the striking plates, so that the window can be opened.

For other solutions, such as the DE 199 28 729 , is locked by means of a combination lock. After setting the appropriate code, the handle is released for opening. To lock, however, the code must then be manually adjusted again. Again, in particular with frequent opening or closing of the window, for reasons of convenience or forgetfulness, the adjustment of the coding omitted, so that a burglar bring after hammering and reaching the level of the window handle this in the open position and can open the window for boarding.

In each case, the techniques currently on the market against attacks on the opening mechanism require an active action by the operator to put these backups into or out of action. Experience shows that this is often omitted for convenience. Therefore, it makes sense to design such backups so that they automatically and forcibly put into effect and that only to override the participation of the operator is required. The self-adjusting coding device on which the invention is based ensures this.

An arrangement of self-adjusting number coding is neither in, on the window handle directly on the base plate to which the window handle is usually screwed, technically feasible. For this reason, a coding wheel is used in the solution on which the invention is based. However, this requires a slightly larger housing to accommodate the mechanics.

Against attacks on the opening mechanism was in the DE 10 2017 001 005.6 and DE 10 2017 004 245.4 set the "bolt lock". It is designed to prevent the above-mentioned attacks. However, this technique is only possible if an improper operation of the handle is prevented.

The closure device on which the invention is based with self-adjusting number coding ensures that an unauthorized person can not operate the handle since he would have to set the correct numerical code, which was not known to him, beforehand. Thus, the "deadbolt lock" in conjunction with the closure device on which the invention is based ensures an extremely high level of security against attacks on the opening mechanism.

• 1 zeigt die der Erfindung zugrunde liegende Verschlusseinrichtung mit selbstverstellender Zahlencodierung 17, mit dem Gehäuse 1, der drehbaren Handhabe 2 und der Zahlencodeeinrichtung 3.
• 2 zeigt in einer Draufsicht die Verschlusseinrichtung mit selbstverstellender Zahlencodierung 17. Im Gehäuse 1 befindet sich ein Teil der drehbaren Handhabe 2 sowie das mit einer Achse 18 drehbar gelagerte Codierrad 6. Mit dem Oberteil des Gehäuses 1 verbunden ist die Zahlencodeeinrichtung 3. Am Codierrad 6 befinden sich fest damit verbundene Beförderungs- und Blockierzapfen 8 sowie aufgebrachte Codierstifte 7. Diese Codierstifte 7 greifen in Aussparungen in den Verstellrädern 5 für die Zahlenräder 6 ein. An der drehbaren Handhabe 2 ist eine Drehachse 11 und mit ihr verbunden ist der Beförderungsstab 10. Dieser Beförderungsstab wird mittels der Feder 15 und deren Widerlager 16 gegen das Codierrad 6 gedrückt. Der Blockierstift 9 liegt so vor dem Beförderungs- und Blockierzapfen 8, dass ein Drehen der Handhabe 2 in dieser Kombination blockiert wird. Nach Einstellen des richtigen Zahlencodes gibt der Blockierstift 9 den Beförderungs- und Blockierzapfen 8 und somit das Codierrad 6 frei, so dass die drehbare Handhabe 2 in Richtung 12 gedreht werden kann. Dabei wird der mit der Handhabe 2 verbundene Beförderungsstab 10 in Richtung 13 gedrückt. Da dieser hinter dem Beförderungs- und Blockierzapfen 8 liegt, dreht er nun zwangsweise das Codierrad 6 in Richtung 14. Bei diesem Drehen greifen die Codierstifte 7 in die Aussparungen 24 der Verstellräder 5 ein und verdrehen dabei die Zahlenräder 4. Gleichzeitig wird der Blockierstift 9 in den Freiraum zwischen den Beförderungs- und Blockierzapfen 8 gelegt und schlägt bei weiterem Drehen wider an den nächsten Beförderungs- und Blockierzapfen 8 an. Die drehbare Handhabe wird nach dem Drehen in Richtung 12 federbedingt wieder in seine Ausgangslage zurück gedreht, wobei sich der Beförderungsstab 10, federbedingt, wieder hinter einen Beförderungs- und Blockierzapfen 8 legt und somit ein erneutes Drehen der Handhabe 2 verhindert.
• 3 zeigt sowohl in einer Drauf- als auch Seitenansicht das Codierrad 6, und zwar von der Ober- und Unterseite. Im linken Bild ist die Oberseite des Codierrades 6 mit den Codierstiften 7, den Beförderungs- und Blockierzapfen 8 und der Achse 18 dargestellt. Das rechte Bild zeigt das Codierrad 6, die Achse 18 sowie Segmente 20 im Codierrad 6. In die Ausnehmungen in den Segmenten 20 greift eine nicht dargestellte Federsperre ein die sich am Boden des Gehäuses befindet. Auf diese Weise wird verhindert, dass sich das Codierrad 6 zurückdrehen kann. Um eine berechenbare Verdrehung der Zahlenräder 4 zu verhindern kann dies durch Weglassen oder Hinzufügen einzelner Codierstifte 7 verhindert werden.
• 4 zeigt sowohl in einer Seitenansicht das Verstellrad 5, das Zahlenrad 4 sowie die Achse 21. In der Draufsicht ist das Zahlenrad 4 abgebildet. Am Zahlenrad 4 sind Segmente 22 ausgebildet in die eine am Verstellrad 5 angebrachte Federsperre 23 eingreift. Auf diese Weise wird über die Codierstifte 7 das Verstellrad 5 und das Zahlenrad 4 beim Drehen der Handhabe weitergedreht. Das Drehen des Zahlenrades 4 zum Einstellen des richtigen Zahlencodes kann somit in nur eine Richtung erfolgen.
• 5 stellt in einer Draufsicht das Verstellrad 5 dar. An ihm gestrichelt dargestellt sind die Aussparungen 24, in die die Codierstifte 7 eingreifen, die Achse 21 sowie die Mitnahmefeder 23 zu ersehen die in die Segmente 22 greift und auf diese Weise ein Mitdrehen des Zahlenrades 4 gewährleistet.
• 6 zeigt in einer anderen Anwendungsform die selbstverstellende Codiereinrichtung 17 als Verschlusseinrichtung mit Fenstergriff als drehbare Handhabe 2.
• 7 stellt, ähnlich wie 6, die selbstverstellende Codiereinrichtung 17 als Verschlusseinrichtung mit versenkbarem Fenstergriff als drehbare Handhabe 2 dar. Die versenkbare Handhabe 2 kann gegen einen nicht dargestellten Federdruck in das Gehäuse 1 eingedrückt werden und verriegelt sich darin. Bei erneutem Drücken auf den versenkten Fenstergriff wird die Verriegelung aufgehoben und der Fenstergriff wird federbedingt wieder zur Bedienung aus dem Gehäuse 1 herausgedrückt.
