Definitions
- the invention relates to a pin tumbler in a rotary lock cylinder for a security lock, with a housing pin and a core pin and one in the housing of the rotary lock cylinder stored compression spring against whose force the guard locking to enable rotation of the cylinder core with one in the key channel key to be inserted by a radial displacement is to be classified, the housing pin being excluded on its circumference immediately behind its end face lying against the core pin, such that an edge is formed with an acute-angled cross section.
- Tumblers of this type are used in high-quality rotary lock cylinders long known in numerous versions.
- Such Guard locking in a rotary lock cylinder is, for example known from the applicant's US-A-3 762 193 and EP-A-0 646 689. These tumblers are used to enable the rotation of the cylinder core with a Key channel key to be inserted raised and arranged, the abutting surfaces of the housing pin and the core pin on the shear line of the rotary lock cylinder lie.
- the housing pin is also called counter bolt.
- Tumblers can block positively or negatively. With a negative Locking locks the body pin by inserting it into the hole engages the cylinder core. If the lock is positive, it takes effect however, the core pin in the bore of the housing and locks the rotary lock cylinder. Such an intervention takes place each with one or more increments. To the Combinatorics and thus increasing the number of locking options, very small increments are used, with the smallest still permissible increments in the range from 0.35 to 0.5 mm.
- a locking system is only set up with positive locks, it is therefore possible to use several individual keys lying next to each other a master key to identify what's security related shouldn't be possible. However, it becomes positive and negative combined, there is a complete concealment the locks, so that a master key even for the professional is not recognizable. Such a disguise will the security value of a locking system increases significantly.
- the invention has for its object a guard locking of the above To create kind that avoids the disadvantages mentioned and that even with a step jump smaller than 1 mm and more negative Blocking offers high security.
- the task is in a generic pin tumbler according to the characterizing features of claim 1 solved.
- the invention has the effect that small step change and negative locking of the housing pin a force application in the housing bore and the Edge buried in the cylinder core.
- By digging in Housing pin must not be lifted out of the hole. tries have shown that the housing pin does not push away even then when the key is broken until it breaks is rotated about 12 N.
- the greater the torque the more the housing pin digs in more at its inner edge the cylinder core.
- Tumblers are therefore also negative blocks possible with a step change significantly smaller than 1 mm and resist an unauthorized attempt to unlock the door.
- FIG. 1 shows a rotary lock cylinder 4 known per se with a cylinder core 2, also called a rotor and a housing 3, also called stator.
- a tumbler 4 which has a core pin 6 and a housing pin 5.
- the core pin 6 engages with its tip 6a in a key channel 15 and lies on further core pins 6 'and 6' '.
- the core pins 6 ' and 6 "belong to tumblers that are the same as tumbler 4 can be built up, but transversely to this in the locking cylinder 4 are stored.
- the tumbler 4 and the other tumblers not shown here are classified by the shaft of one not shown here Key is inserted into channel 6.
- the tumblers 4 are radially outwards in the direction of line 15 raised against the retroactive force of a compression spring 7 until the cambered surface 12 of the core pins 6 between the shear line 10 have reached the housing 3 and the cylinder core 2.
- the Core pin 6 and the housing pin 5 complement each other in length.
- the housing pins 5 are thus of different lengths, the shortest housing pin 5 has a length of about 0.65 mm. Such a housing pin 5 never locks negatively.
- the housing pin 5 locks negatively, that is, it grips with the length of a step S of, for example, 0.5 mm in the bore 8 of the cylinder core 2 a.
- the end face 11 of the housing pin 5 is by the Pressure of the spring 7 is pressed against the end face 12 of the core pin 6.
- the housing pin 5 is immediate provided with a recess 13 behind its end face, which extends around the entire circumference of the housing pin 5.
- the result of this recess 13 is that the housing pin 15 has a comparatively sharp front edge 16. Behind this edge 16, the diameter takes along a conical Surface 14 up to a sloping shoulder 17 continuously from.
- the angle ⁇ between the surface 14 and the shoulder 17 is about 105 °.
- the angle a between the end face 11 and the conical surface 14 is smaller than 90 ° and preferably larger than 60 °.
- the preferred angle ⁇ is between 85 ° and 65 ° and is preferably about 75 °.
- the diameter A of the housing pin 5 is slightly smaller than the diameter of the bore 9 and is for example 2.97 mm.
- the length B of the housing pin is different, but is at least about 0.65 mm.
- the distance C between the end face 11 and the shoulder 17th is slightly larger than an increment S and is around here 0.75 mm.
- the recess 13 is not very deep and in no way weakens the housing pin 5.
- the housing pin 5 tilts as in Figure 2 shown and the comparatively sharp edge 16 digs the point designated P in the cylinder core 2. Becomes the torque increases, the housing pin 5 is not from the Hole 8 lifted out, but he digs with increasing Force continues in those made of comparatively soft material Cylinder core 2 and can not be radial be pressed outside.
- the housing pin 5 By tilting the housing pin 5 the distance of the edge 16 starting at the bore 8 to Shear line 10 enlarged.
- the distance of the shear line 10 to Point P is thus much larger than the step jump S.
- the correspondingly large material thickness makes it difficult to push away the material of the cylinder core 2 lying above the point P. and thus remove the block. This is also with a force of about 12 N, in which a key usually breaks, not possible.
- the housing pin consists of hard material, especially hardened steel and is on his inner end not significantly weakened by the recess 13.
- the recess 13 can also be designed differently and the surface 14 does not necessarily have to be conical. However, it is essential that the edge 16 is comparatively sharp and as above explained can dig into the cylinder core and thus in the hole 8 fixed.
- the recess 13 can be inexpensive by turning or stabbing.
- the housing pin 5 Over the conical surface 14, the housing pin 5 has a cylindrical Wall 19 with which the housing pin 5 in the Bore 9 of the housing 3 is guided radially. It is not necessary that all tumblers of a rotary lock cylinder are designed as explained above. Are preferred however, all housing pins 5 which engage in the cylinder core and lock negative, provided with a recess 13. The shorter ones Housing pins 5 with a length of about 0.65 mm can be trained as usual.
- FIGS. 4 and 5 show a housing pin 20 according to a variant, which is provided with the recess 13 explained above.
- the housing pin 20 consists of a hardened body 23, in which a softer part 24 is used, which as can be seen has an outstanding conical projection 24a.
- Approach 24a can be the compression spring 7 in a simple manner attach by tapered end 24a after attaching the Compression spring 7 is compressed like a rivet.
- the Compression spring 7 and the housing pin 20 then form a unit, which makes assembly much easier.
- FIG. 6 shows a further embodiment of a housing pin 25. This is in turn provided with a recess 13.
- the compression spring 7 is attached to the housing pin 15 here by means of a groove 17 into which end turns 28 of the compression spring 7 are clipped in.
- the compression spring 7 is double-conical, so that they are essentially compressed to the wire diameter can be.
- the compression spring with the housing pin 25 can thus in a comparatively short bore 9 of the housing 3 can be accommodated.

Description
Die Erfindung betrifft eine Stiftzuhaltung in einem Drehschliesszylinder für ein Sicherheitsschloss, mit einem Gehäusestift und einem Kernstift und einer im Gehäuse des Drehschliesszylinders gelagerten Druckfeder, gegen deren Kraft die Zuhaltung zur Drehfreigabe des Zylinderkerns mit einem in den Schlüsselkanal einzuführenden Schlüssel durch eine radiale Verschiebung einzuordnen ist, wobei der Gehäusestift an seinen Umfang unmittelbar hinter seiner am Kernstift anliegenden Stirnseite ausgenommen ist, derart, dass eine Kante mit einem spitzwinkligen Querschnitt gebildet ist.The invention relates to a pin tumbler in a rotary lock cylinder for a security lock, with a housing pin and a core pin and one in the housing of the rotary lock cylinder stored compression spring against whose force the guard locking to enable rotation of the cylinder core with one in the key channel key to be inserted by a radial displacement is to be classified, the housing pin being excluded on its circumference immediately behind its end face lying against the core pin, such that an edge is formed with an acute-angled cross section.
Zuhaltungen dieser Art sind bei hochwertigen Drehschliesszylindern seit langem in zahlreichen Ausführungen bekannt. Eine solche Zuhaltung in einem Drehschliesszylinder ist beispielsweise aus der US-A-3 762 193 und der EP-A-0 646 689 des Anmelders bekannt. Diese Zuhaltungen werden zur Drehfreigabe des Zylinderkerns mit einem in den Schlüsselkanal einzuführenden Schlüssel angehoben und eingeordnet, wobei die aneinander anliegenden Flächen des Gehäusestiftes und des Kernstiftes auf der Scherlinie des Drehschliesszylinders liegen. Der Gehäusestift wird auch Gegenbolzen genannt.Tumblers of this type are used in high-quality rotary lock cylinders long known in numerous versions. Such Guard locking in a rotary lock cylinder is, for example known from the applicant's US-A-3 762 193 and EP-A-0 646 689. These tumblers are used to enable the rotation of the cylinder core with a Key channel key to be inserted raised and arranged, the abutting surfaces of the housing pin and the core pin on the shear line of the rotary lock cylinder lie. The housing pin is also called counter bolt.
Zuhaltungen können positiv oder negativ sperren. Bei einer negativen Sperrung sperrt der Gehäusestift, indem er in die Bohrung des Zylinderkerns eingreift. Bei einer positiven Sperrung greift hingegen der Kernstift in die Bohrung des Gehäuses ein und sperrt damit den Drehschliesszylinder. Ein solcher Eingriff erfolgt jeweils mit einem oder mehreren Stufensprüngen. Um die Kombinatorik und somit die Anzahl der Schliessvarianten zu erhöhen, werden sehr kleine Stufensprünge verwendet, wobei die kleinsten noch zulässigen Stufensprünge im Bereich von 0,35 bis 0,5 mm liegen.Tumblers can block positively or negatively. With a negative Locking locks the body pin by inserting it into the hole engages the cylinder core. If the lock is positive, it takes effect however, the core pin in the bore of the housing and locks the rotary lock cylinder. Such an intervention takes place each with one or more increments. To the Combinatorics and thus increasing the number of locking options, very small increments are used, with the smallest still permissible increments in the range from 0.35 to 0.5 mm.
Wird eine Schliessanlage nur mit positiven Sperrungen aufgebaut, so ist es möglich, aus mehreren nebeneinander liegenden Einzelschlüsseln einen Hauptschlüssel zu erkennen, was sicherheitstechnisch nicht möglich sein sollte. Wird jedoch positiv und negativ kombiniert, so entsteht eine vollständige Verschleierung der Schliessungen, so dass ein Hauptschlüssel auch für den Fachmann nicht erkennbar ist. Durch eine solche Verschleierung wird der Sicherheitswert einer Schliessanlage wesentlich erhöht.If a locking system is only set up with positive locks, it is therefore possible to use several individual keys lying next to each other a master key to identify what's security related shouldn't be possible. However, it becomes positive and negative combined, there is a complete concealment the locks, so that a master key even for the professional is not recognizable. Such a disguise will the security value of a locking system increases significantly.
Beim Aufbau einer hochwertigen Schliessanlage ist es deshalb sehr wichtig, dass die Unterteilung in Hauptgruppen, Gruppen und Einzelschliessungen berechnungstechnisch mit positiven und negativen Sperrungen aufgebaut wird.It is therefore when building a high-quality locking system very important that the division into main groups, groups and Single locks with positive and negative calculations Blockages is built.
Die oben erwähnten kleinen Stufensprünge geben bei präzise gefertigten Schliesszylindern mit kleinem Kern- und Gehäusespiel und positiver Sperrung wenig Probleme. Kommt aber nun eine negative Sperrung mit nur einem Stufensprung zum Tragen, kann der Schliesszylinder mit einem nicht zugehörigen Einzelschlüssel dieser Gruppe problemlos durchgedrückt werden und damit kann mit diesem nicht berechtigten Schlüssel geöffnet werden. Ein Stufensprung von 0,5 mm reicht hier somit nicht aus, um den Zylinderkern zu sperren. Beim Durchdrücken wird Material des Zylinderkerns weggedrückt und damit der Zylinderkern verletzt. Der Drehschliesszylinder mit dem verletzten Zylinderkern kann nun mit dem unberechtigten Einzelschlüssel jederzeit problemlos geöffnet werden. In einigen Fällen wird der Gehäusestift auch ohne wesentliche Verletzung des Zylinderkerns aus der Bohrung herausgehoben. Um dies zu verhindern, war bisher für eine sichere negative Sperrung ein Stufensprung von wenigstens 0,9 mm notwendig.The small increments mentioned above give precisely manufactured Lock cylinders with a small core and housing play and positive blocking few problems. But now comes a negative Blocking with only one step jump to carry, the Lock cylinder with a non-associated single key This group can be pushed through without any problems and can be used with be opened with this unauthorized key. A step jump of 0.5 mm is therefore not sufficient here around the cylinder core to lock. When pushing through the material of the cylinder core pushed away and thus injured the cylinder core. The rotary lock cylinder with the injured cylinder core can now with the unauthorized individual key can be opened at any time become. In some cases, the body pin is also without essential Lift the cylinder core injury out of the hole. To prevent this from happening, it was previously safe for a negative Blocking requires a step change of at least 0.9 mm.
Der Erfindung liegt die Aufgabe zugrunde, eine Zuhaltung der genannten Art zu schaffen, welche die genannten Nachteile vermeidet und die auch bei einem Stufensprung kleiner als 1 mm und negativer Sperrung hohe Sicherheit bietet.The invention has for its object a guard locking of the above To create kind that avoids the disadvantages mentioned and that even with a step jump smaller than 1 mm and more negative Blocking offers high security.
Die Aufgabe wird bei einer gattungsgemässen Stiftzuhaltung gemäß den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Die Erfindung hat die Wirkung, dass bei kleinem Stufensprung und negativer Sperrung der Gehäusestift bei einer Kraftanwendung in der Gehäusebohrung kippt und sich die Kante in den Zylinderkern eingräbt. Durch das Eingraben kann der Gehäusestift nicht aus der Bohrung herausgehoben werden. Versuche haben gezeigt, dass der Gehäusestift auch dann nicht weggedrückt werden kann, wenn der Schlüssel bis zu seinem Bruch mit etwa 12 N gedreht wird. Je grösser das Drehmoment ist, umso stärker gräbt sich der Gehäusestift an seiner inneren Kante in den Zylinderkern ein. Bei einem Drehschliesszylinder mit erfindungsgemässen Zuhaltungen sind deshalb auch negative Sperrungen mit einem Stufensprung wesentlich kleiner als 1 mm möglich und widerstehen einem unberechtigten Aufsperrversuch.The task is in a generic pin tumbler according to the characterizing features of claim 1 solved. The invention has the effect that small step change and negative locking of the housing pin a force application in the housing bore and the Edge buried in the cylinder core. By digging in Housing pin must not be lifted out of the hole. tries have shown that the housing pin does not push away even then when the key is broken until it breaks is rotated about 12 N. The greater the torque, the more the housing pin digs in more at its inner edge the cylinder core. In a rotary lock cylinder with according to the invention Tumblers are therefore also negative blocks possible with a step change significantly smaller than 1 mm and resist an unauthorized attempt to unlock the door.
Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüche, der nachfolgenden Beschreibung sowie den Zeichnungen.Further advantageous features result from the dependent ones Claims, the following description and the drawings.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand
der Zeichnung näher erläutert. Es zeigen:
Die Figur 1 zeigt einen an sich bekannten Drehschliesszylinder 4
mit einem Zylinderkern 2, auch Rotor genannt und einem Gehäuse
3, auch Stator genannt.FIG. 1 shows a
In radialen Bohrungen 8 und 9 des Zylinderkerns 2 beziehungsweise
des Gehäuses 3 ist eine Zuhaltung 4 gelagert, die einen Kernstift
6 sowie einen Gehäusestift 5 aufweist. Der Kernstift 6
greift mit seiner Spitze 6a in einen Schlüsselkanal 15 ein und
liegt an weiteren Kernstiften 6' und 6'' an. Die Kernstifte 6'
und 6" gehören zu Zuhaltungen, die gleich wie die Zuhaltung 4
aufgebaut sein können, jedoch quer zu dieser im Schliesszylinder
4 gelagert sind.In
Die Zuhaltung 4 und die weiteren hier nicht gezeigten Zuhaltungen
werden eingeordnet, indem der Schaft eines hier nicht gezeigten
Schlüssels in den Kanal 6 eingeführt wird. Die Zuhaltungen
4 werden hierbei in Richtung der Linie 15 radial nach aussen
gegen die rückwirkende Kraft einer Druckfeder 7 angehoben, bis
die bombierte Fläche 12 der Kernstifte 6 die Scherlinie 10 zwischen
dem Gehäuse 3 und dem Zylinderkern 2 erreicht haben. Der
Kernstift 6 und der Gehäusestift 5 ergänzen sich in der Länge.
Die Gehäusestifte 5 sind somit unterschiedlich lang, wobei der
kürzeste Gehäusestift 5 eine Länge von etwa 0,65 mm aufweist.
Ein solcher Gehäusestift 5 sperrt nie negativ.The
Bei der Anordnung gemäss Figur 1 sperrt der Gehäusestift 5 negativ,
das heisst, er greift mit der Länge eines Stufensprunges S
von beispielsweise von 0,5 mm in die Bohrung 8 des Zylinderkerns
2 ein. Die Stirnseite 11 des Gehäusestiftes 5 wird durch den
Druck der Feder 7 an die Stirnfläche 12 des Kernstifts 6 angepresst. In the arrangement according to FIG. 1, the
Wie insbesondere die Figur 3 zeigt, ist der Gehäusestift 5 unmittelbar
hinter seiner Stirnfläche mit einer Ausnehmung 13 versehen,
die sich um den gesamten Umfang des Gehäusestiftes 5 erstreckt.
Diese Ausnehmung 13 hat zur Folge, dass der Gehäusestift
15 eine vergleichsweise scharfe vordere Kante 16 besitzt.
Hinter dieser Kante 16 nimmt der Durchmesser entlang einer konischen
Fläche 14 bis zu einer schrägen Schulter 17 kontinuierlich
ab. Der Winkel β zwischen der Fläche 14 und der Schulter 17 beträgt
etwa 105°. Der Winkel a zwischen der Stirnseite 11 und der
konischen Fläche 14 ist kleiner als 90° und vorzugsweise grösser
als 60°. Der bevorzugte Winkel α liegt zwischen 85° und 65° und
beträgt vorzugsweise etwa 75°. Der Durchmesser A des Gehäusestiftes
5 ist etwas kleiner als der Durchmesser der Bohrung 9
und beträgt beispielsweise 2,97 mm. Die Länge B des Gehäusestiftes
ist unterschiedlich, beträgt aber wenigstens etwa 0,65 mm.
Der Abstand C zwischen der Stirnfläche 11 und der Schulter 17
ist etwas grösser als ein Stufensprung S und beträgt hier etwa
0,75 mm. Die Ausnehmung 13 ist wie ersichtlich nicht sehr tief
und schwächt keineswegs den Gehäusestift 5.As shown in Figure 3 in particular, the
Wird nun der Zylinderkern 2 im Uhrzeigersinn in Richtung des
Pfeiles 18 gedreht, so kippt der Gehäusestift 5 wie in Figur 2
gezeigt und die vergleichsweise scharfe Kante 16 gräbt sich an
der mit P bezeichneten Stelle in den Zylinderkern 2 ein. Wird
das Drehmoment erhöht, so wird der Gehäusestift 5 nicht aus der
Bohrung 8 herausgehoben, sondern er gräbt sich mit zunehmender
Kraft weiter in den aus vergleichsweise weichem Werkstoff hergestellten
Zylinderkern 2 ein und kann damit nicht radial nach
aussen gedrückt werden. Durch das Kippen des Gehäusestiftes 5
wird der Abstand der an der Bohrung 8 ansetzenden Kante 16 zur
Scherlinie 10 vergrössert. Der Abstand der Scherlinie 10 zum
Punkt P ist damit wesentlich grösser als der Stufensprung S.
Durch die entsprechend grosse Materialstärke wird es schwierig,
das über dem Punkt P liegende Material des Zylinderkerns 2 wegzudrücken
und damit die Sperrung aufzuheben. Dies ist auch bei
einer Kraftaufwendung von etwa 12 N, bei welcher ein Schlüssel
in der Regel bricht, nicht möglich. Der Gehäusestift besteht aus
hartem Werkstoff, insbesondere gehärtetem Stahl und ist an seinem
inneren Ende durch die Ausnehmung 13 nicht wesentlich geschwächt.If the
Die Ausnehmung 13 kann auch anders ausgebildet sein und die Fläche
14 muss nicht zwingend konisch sein. Wesentlich ist jedoch,
dass die Kante 16 vergleichsweise scharf ist und sich wie oben
erläutert in den Zylinderkern eingraben kann und sich damit in
der Bohrung 8 fixiert. Die Ausnehmung 13 kann kostengünstig
durch Hinterdrehen oder Hinterstechen hergestellt werden.The
Über der konischen Fläche 14 weist der Gehäusestift 5 eine zylindrische
Wandung 19 auf, mit welcher der Gehäusestift 5 in der
Bohrung 9 des Gehäuses 3 radial verschiebbar geführt ist. Es ist
nicht notwendig, dass sämtliche Zuhaltungen eines Drehschliesszylinders
wie oben erläutert ausgebildet sind. Vorzugsweise sind
jedoch alle Gehäusestifte 5, die in den Zylinderkern eingreifen
und negativ sperren, mit einer Ausnehmung 13 versehen. Die kürzeren
Gehäusestifte 5 mit einer Länge von etwa 0,65 mm können
wie bisher üblich ausgebildet sein.Over the
Die Figuren 4 und 5 zeigen einen Gehäusestift 20 nach einer Variante,
der mit der oben erläuterten Ausnehmung 13 versehen ist.
Der Gehäusestift 20 besteht aus einem gehärteten Körper 23, in
den ein weicherer Teil 24 eingesetzt ist, welcher wie ersichtlich
einen herausragenden konischen Ansatz 24a aufweist. An diesem
Ansatz 24a lässt sich die Druckfeder 7 in einfacher Weise
befestigen, indem das konische Ende 24a nach dem Aufsetzen der
Druckfeder 7 ähnlich einer Niete zusammengedrückt wird. Die
Druckfeder 7 und der Gehäusestift 20 bilden dann eine Einheit,
was die Montage wesentlich erleichtert.FIGS. 4 and 5 show a
Die Figur 6 zeigt eine weitere Ausführung eines Gehäusestiftes
25. Dieser ist wiederum mit einer Ausnehmung 13 versehen. Die
Befestigung der Druckfeder 7 am Gehäusestift 15 erfolgt hier
mittels einer Nut 17, in welche Endwindungen 28 der Druckfeder 7
eingeklipst sind. Die Druckfeder 7 ist wie ersichtlich doppelkonisch,
so dass sie im wesentlichen auf den Drahtdurchmesser zusammengedrückt
werden kann. Die Druckfeder mit dem Gehäusestift
25 kann damit in einer vergleichsweise kurzen Bohrung 9 des Gehäuses
3 untergebracht werden.FIG. 6 shows a further embodiment of a
