Description

Die Erfindung betrifft einen Knaufzylinder, dessen Knaufwelle oder -spindel drehfest mit dem Schließbart eines Schließzylinders verbunden ist.The invention relates to a knob cylinder, the knob shaft or spindle is rotatably connected to the cam of a lock cylinder.

Bei Schließzylinder, die ausschließlich mit einem Schlüssel betätigt werden, kann der Schlüssel nur in einer definierten Stellung des Schlüssels abgezogen werden.For lock cylinders, which are operated only with a key, the key can only be removed in a defined position of the key.

Demgegenüber haben Knaufzylinder meist keine feste Position bei der Verdrehung des Knaufes, die dieser Grund- oder Neutralstellung entspricht.
Knaufzylinder können von der Außenseite entweder mit dem Schlüssel oder einem elektronischen Knauf betätigt werden.In contrast, knob cylinder usually have no fixed position in the rotation of the knob, which corresponds to this basic or neutral position.
Knob cylinders can be operated from the outside either with the key or an electronic knob.

Insbesondere bei Schließzylindern, die von außen nicht mit einem Schlüssel sondern über einen Elektronikknauf und von Innen mit einem mechanischen Knauf zu öffnen sind, gibt es meist keine feste Schließbartposition. die z. B. bei Paniktüren, Fluchtwegtüren oder auch Feuerschutztüren erforderlich ist.
Bei diesen Schließzylindern besteht die Forderung, dass das Stellglied des Schließzylinders nach einem ausgeführten Schließvorgang, immer in seiner Grundstellung oder Neutralstellung im Bereich von 3:00 bis 9:00Uhr stehen muss, um beispielsweise die Panikfunktion ausüben zu können.Especially with lock cylinders, which are not to be opened from the outside with a key but via an electronic knob and from the inside with a mechanical knob, there is usually no fixed cam position. the z. B. panic doors, escape route doors or fire doors is required.
These lock cylinders require that the actuator of the lock cylinder after a completed closing operation, always in its normal position or neutral position in the range of 3:00 to 9:00 o'clock, for example, to exercise the panic function.

Aus der EP 2 088 263 B1 ist es bekannt eine Rückstellfeder vorzusehen, die in diesem Fall dazu dient, den aus einer Neutralstellung verdrehten Zylinderkern selbsttätig in diese Neutralstellung zurückzudrehen.From the EP 2 088 263 B1 It is known to provide a return spring, which serves in this case, to turn back the twisted from a neutral position cylinder core automatically in this neutral position.

Eine andere, ebenfalls auf die Wirkung einer Feder aufbauende Rückstelleinrichtung ist aus der EP 2 115 246 B1 bekannt.Another, also based on the action of a spring reset device is from the EP 2 115 246 B1 known.

Nachteilig bei den bisher bekannten Lösungen ist, dass ein nicht unerheblicher Bauraum konstruktiv bedingt eingenommen wird bzw. notwendig ist, um die Rückstellfedern unterzubringen. Dies bedeutet,dass die konstruktiven Elemente sowohl in der Knaufwelle wie auch im Zylindergehäuse angeordnet sind.A disadvantage of the previously known solutions is that a considerable space is taken constructively due or is necessary to accommodate the return springs. This means that the structural elements are arranged both in the knob shaft and in the cylinder housing.

Ein weiterer Nachteil besteht darin, dass sich Totpunkte bei Rückstellfedern nicht vermeiden lassen, d. h. es gibt bestimmte Stellungen des Stellgliedes und damit des Schließbartes, bei denen die Rückstellfeder an einer Rückdrehung in die Grund- oder Neutralstellung gehindert ist.
Damit kann unter Umständen die Panikfunktion nicht ausgeübt werden, zumindest nicht sicher genug.Another disadvantage is that dead points in return springs can not be avoided, ie there are certain positions of the actuator and thus the cam, in which the return spring is prevented from turning back into the basic or neutral position.
Thus, under certain circumstances, the panic function can not be exercised, at least not sure enough.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Knaufzylinder bereitzustellen, bei dem der Schließbart zwangsmäßig nach einem Schließvorgang in eine Position zwischen 3:00 Uhr und 9:00 Uhr gebracht wird, und zwar möglichst ohne das bei der Rückstellbewegung ein Totpunkt vorhanden ist, so dass damit die Voraussetzungen für den Einbau in z. B. Brandschutztüren, Paniktüren oder Fluchtwegtüren gegeben sind.The invention is therefore based on the object to provide a knob cylinder, in which the cam is brought forcibly after a closing operation in a position between 3:00 clock and 9:00 clock, and if possible without a dead center in the return movement, so that thus the conditions for installation in z. As fire doors, panic doors or escape route doors are given.

Ein weiterer, wesentlicher Punkt ist, dass die Rückstelleinrichtung einen möglichst geringen Bauraum einnimmt, insbesondere, dass sie auch in bestehende Schließzylinder ohne großen Aufwand, beispielsweise nachträglich, einbaubar ist.Another essential point is that the restoring device occupies the smallest possible space, in particular, that it can be installed in existing lock cylinder without much effort, for example subsequently.

Gelöst wird diese Aufgabe erfindungsgemäß mit einem Knaufzylinder, dessen Knaufwelle oder -spindel drehfest mit dem Schließbart eines Schließzylinder verbunden ist,
wobei zur Rückstellung des Schließbartes in eine Grundstellung, eine auf die Knaufwelle drehend wirkende Magnetanordnung vorgesehen ist.This object is achieved according to the invention with a knob cylinder, the knob shaft or spindle is rotatably connected to the cam of a lock cylinder,
wherein for the provision of the cam in a basic position, a rotating on the knob shaft acting magnet arrangement is provided.

Gemäß einer vorzugsweisen Ausführung ist vorgesehen, dass auf der Knaufwelle axial hintereinander mehrere die Knaufwelle umgebende Magnetscheiben angeordnet sind, die abwechselnd gegenpolig ausgerichtet sind und jeweils aus zwei oder mehr Segmenten bestehen, wobei jeweils eine der Magnetscheiben gegenüber dem die Knaufwelle aufnehmenden Schließzylindergehäuse verdrehfest gehalten ist und die zugeordnete axial nächstliegende Magnetscheibe gegenüber der Knaufwelle drehfest gehalten ist und die Magnetpolungen so gewählt sind, dass die mit der Knaufwelle verbundene Magnetscheibe ständig in die Grundstellung zurückgedreht wird.According to a preferred embodiment, it is provided that on the knob shaft axially successively surrounding the knob shaft magnetic discs are arranged, which are alternately oriented in opposite directions and each consist of two or more segments, each one of the magnetic discs against the knob shaft receiving lock cylinder housing is held against rotation and the associated axially closest magnetic disc is held against rotation with respect to the knob shaft and the magnetic poles are selected such that the magnetic disc connected to the knob shaft is constantly rotated back into the basic position.

Diese Lösung zeichnet sich insbesondere dadurch aus, dass das Rückstellsystem keinen Totpunkt aufweist.This solution is characterized in particular by the fact that the reset system has no dead center.

Die Lösung besteht darin, dass eine "gehäusefeste" Magnetscheibe (bestehend aus zwei oder mehreren Segmenten) sich zwischen zwei (oder mehreren) gleich / ungleich gepolten Magnetscheiben befindet. Die gehäusefeste Magnetscheibe hält ihre Lage beispielsweise über eine kleine "Nase", die in eine Gehäusenut eingreift. Die beiden anderen Magnetscheiben, zwischen denen sich die gehäusefeste Magnetscheibe befindet, sind fest mit der Knaufwelle verbunden. Die Magnetpolungen sind nun so gewählt, dass die mittlere Magnetscheibe im "Ruhezustand" von den beiden äußeren Magnetscheiben angezogen wird. Wird die Knaufwelle nun verdreht, dann kommen die zylinderfesten Magnetsegmente in den abstoßend gepolten Bereich der äußeren Magnetsegmente und werden davon zurückgedreht.
Bei einer mittleren Magnetscheibe. die mit zwei benachbarten Magnetscheiben in Wirkung tritt, treten keine äußeren Magnetkräfte auf, da sich die äußeren Magnetscheiben zur mittleren Magnetscheibe zentrieren.The solution is that a "fixed" magnetic disk (consisting of two or more segments) is located between two (or more) equal / unevenly polarized magnetic disks. The housing-fixed magnetic disk keeps its position, for example, via a small "nose", which engages in a housing groove. The two other magnetic disks, between which the magnetic disk fixed to the housing, are firmly connected to the knob shaft. The magnetic poles are now chosen so that the middle magnetic disk is attracted in the "resting state" of the two outer magnetic disks. If the knob shaft is now twisted, then the cylinder-fixed magnet segments come in the repulsively polarized area of the outer magnet segments and are rotated back by it.
At a middle magnetic disk. which comes into effect with two adjacent magnetic disks, no external magnetic forces occur because the outer magnetic disks center to the middle magnetic disk.

Bei einer Anordnung mit jeweils nur einer gehäusefesten und einer drehbaren Magnetscheibe treten dagegen axiale Kräfte auf. Die zurückdrehend wirkende Funktion der beiden Magnetscheiben ist aber gegeben.In an arrangement with only one housing-fixed and a rotatable magnetic disk, however, occur on axial forces. The retro-rotating effect of the two magnetic disks is given.

Bei dieser Lösung kommen - wie beschrieben - Magnetscheiben zum Einsatz.In this solution - as described - magnetic disks are used.

Nach einer anderen Ausführungsform der Erfindung ist vorgesehen, dass die Knaufwelle koaxial umgebend mindestens zwei gegenpolig ausgerichtete Magnetringe vorgesehen sind, wobei der innere Magnetring verdrehfest gegenüber der Knaufwelle und der äußere Magnetring verdrehfest gegenüber dem Schließzylindergehäuse gehalten ist und die Magnetpolungen so gewählt sind, dass der mit der Knaufwelle verbundene Magnetring ständig in die Grundstellung zurückgedreht wird.According to another embodiment of the invention, it is provided that the knob shaft coaxially surrounding at least two mutually oppositely oriented magnetic rings are provided, wherein the inner magnetic ring against rotation of the knob shaft and the outer magnetic ring against rotation of the lock cylinder housing is held and the magnetic poles are chosen so that with the knob shaft connected magnetic ring is constantly rotated back to the normal position.

Hierbei kommen somit nicht Magnetscheiben zu Einsatz, also Magnete, bei denen die axiale Erstreckung aufgrund der scheibenartigen Ausbildung , gering ist, sondern Magnetringe, die eine vergleichsweise größere axiale Länge (oder Breite) aufweisen.Magnetic disks are therefore not used here, ie magnets in which the axial extent due to the disk-like design is small, but magnetic rings which have a comparatively larger axial length (or width).

Darüber hinaus sind diese Magnetringe koaxial angeordnet, d. h. liegen ineinander.In addition, these magnetic rings are arranged coaxially, ie lie inside each other.

Die magnetisierten Bereiche können bei dieser Lösung entweder diametral sein, d.h. in Umfangsrichtung gesehen wechselt sich die Polarität ab, oder sie können radial ausgerichtet sein.
Bei dieser radialen Ausrichtung weist der Innenumfang des Magnetringes eine andere Polarität auf als der Außenumfang, wobei natürlich bei dem zugehörigen , koaxial angeordneten Magnetring, die Polarität beispielsweise am Außenumfang entgegengesetzt der des Innenumfangs des anderen Magnetringes ist.
Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen erläutert werden.The magnetized areas may be either diametrical in this solution, ie seen in the circumferential direction, the polarity alternates, or they may be radially aligned.
In this radial orientation, the inner circumference of the magnetic ring has a different polarity than the outer circumference, wherein, of course, in the associated, coaxially arranged magnetic ring, the polarity, for example, on the outer circumference opposite to the inner circumference of the other magnetic ring.
The invention will be explained below with reference to the drawings.

Die Figur 1 zeigt schematisch einen Knaufzylinder, bei dem sich auf auf der einen Seite der nur teilweise dargestellte, mit einem elektronischen Knaufzylinder oder mit einem Schlüssel zu betätigende Schließzylinder 3 befindet. Auf der gegenüber liegenden Seite ist ein Knauf 1 angedeutet. Das Schließzylindergehäuse ist mit 2 bezeichnet.
Das die Knaufwelle 7 (Figur 2a und b) mit dem Zylinderkern des Schließzylinders verbindende, den Schließbart 5 aufnehmende Schließglied ist mit 4 bezeichnet.
Der Schnitt A-A in Figur 2a zeigt eine der Magnetscheiben 6 mit den unterschiedlichen Polaritäten. Diese Magnetscheibe 6 umschließt die Knaufwelle 7, wobei diese in der Magnetscheibe drehbar angeordnet ist. Diese Magnetscheibe 7 selbst ist aber durch eine Nase 8, die in eine Ausnehmung 9 im Schließzylindergehäuse 2 eingreift gegenüber diesem verdrehfest gehalten.
Der Schnitt B-B in Figur 2b gibt die axial benachbarte Magnetscheibe 10 wieder, wobei erkennbar ist, dass diese mit der Knaufwelle 7 verdrehfest verbunden ist.The FIG. 1 schematically shows a knob cylinder, in which on one side of the only partially shown, with an electronic knob cylinder or with a key to be operated lock cylinder 3 is located. On the opposite side a knob 1 is indicated. The lock cylinder housing is designated 2.
That the knob shaft 7 ( FIGS. 2a and b ) connected to the cylinder core of the lock cylinder, the cam 5 receiving the closing member is denoted by 4.
The cut AA in FIG. 2a shows one of the magnetic disks 6 with the different polarities. This magnetic disk 6 encloses the knob shaft 7, wherein this is rotatably arranged in the magnetic disk. However, this magnetic disk 7 itself is held by a nose 8, which engages in a recess 9 in the lock cylinder housing 2 against this rotationally.
The cut BB in FIG. 2b indicates the axially adjacent magnetic disk 10 again, wherein it can be seen that this is rotationally connected to the knob shaft 7.

Wird die Knaufwelle 7 verdreht, so dreht sich die Magnetscheibe 10 mit dieser und relativ zu der vom Schließzylindergehäuse arretierten Magnetscheibe 6. Aufgrund der entgegengesetzten Polaritäten wirkt damit die Magnetkraft rückstellend auf die Knaufwelle ein, so dass diese in eine Grundstellung oder Neutralstellung, wie sie in der Figur 2a dargestellt ist, zurück gedreht wird.If the knob shaft 7 is rotated, the magnetic disk 10 rotates with this and relative to the locked by the lock cylinder housing magnetic disk 6. Due to the opposite polarities acts so that the magnetic force resettable to the knob shaft, so that these in a basic position or neutral position, as shown in the FIG. 2a is shown, is turned back.

Selbstverständlich können die Magnetscheiben auch in mehrere Segmente unterteilt sein.Of course, the magnetic disks can also be divided into several segments.

Die Detaildarstellung in Figur 3 zeigt die axiale nebeneinander Anordnung der Magnetscheiben 6 und 10, wobei bei diesem Ausführungsbeispiel einer Magnetscheibe 6 beidseitig die Magnetscheiben 10 zugeordnet sind.
Mit 11 sind die axiale Position der Magnetscheiben festlegende Mittel bezeichnet.The detailed representation in FIG. 3 shows the axial juxtaposition of the magnetic disks 6 and 10, wherein in this embodiment, a magnetic disk 6 on both sides of the magnetic disks 10 are assigned.
Denoted at 11 are the axial position of the magnetic disk defining means.

Bei der zweiten Ausführungsart, wie sie in den Figuren 4 und 5 dargestellt worden ist, wurden die Magnetscheiben, die eine nur geringe axiale Erstreckung oder Breite aufweisen, durch Magnetringe ersetzt.In the second embodiment, as in the FIGS. 4 and 5 has been shown, the magnetic disks, which have only a small axial extent or width, replaced by magnetic rings.

Darüber hinaus sind die Magnetringe nun beispielsweise - wie in der Figur 4 dargestellt - koaxial ineinander angeordnet.In addition, the magnetic rings are now, for example - as in the FIG. 4 represented - coaxially arranged one inside the other.

Beim äußeren Magnetring 12 ist die Nase 13 erkennbar, d. h. dieser Magnetring ist gegenüber dem hier nicht dargestellten Schließzylindergehäuse verdrehfest gehalten.When outer magnet ring 12, the nose 13 can be seen, d. H. This magnetic ring is held against rotation relative to the lock cylinder housing, not shown here.

Der koaxial innere Magnetring 14 befindet sich auf der Knaufwelle bzw. wird mit dieser verdrehfest verbunden.The coaxial inner magnet ring 14 is located on the knob shaft or is connected to this rotationally fixed.

Die Magnetisierung ist bei diesen Magnetringen, ähnlich wie bei den vorher beschriebenen Magnetscheiben, diametral.The magnetization is diametrical in these magnetic rings, similar to the previously described magnetic disks.

Konstruktiv ist die Variante nach Figur 5 genauso aufgebaut, mit dem Unterschied, dass hier die Magnetisierung radial ist, also auf dem jeweiligen Innenumfang anders als auf dem Außenumfang des Magnetringes.The variant is constructive FIG. 5 constructed the same way, with the difference that here the magnetization is radial, that is different on the respective inner circumference than on the outer circumference of the magnetic ring.
