WO 03/004806 WO (JItNJ8(16PCT/ATJ2/00124 "Profiisystem zur Querschnittsausbildung von Flachschlaisseln sowie von Schlf{4sselkan.- len" TECHNFSCHE GEBIET Die Erfindung betrifft emn Profilsystem zur Querschnittsausbildung von Flachschliisseln mit, ta Wesentlichen ebenen und dmui Aherrid parallelen Flachs,-ei Len sowie van korrespondierenden Schlt~sselkanalen in Schliei~zylindern, insbesondere far den Aufbau von SchiieBanlagen, mit Rippen bzw. Nuten an den Flachseiten des Schlasselbartes b)zw. des Schi~sselkanals, die als Variaticnsprofilelemente und als EFhrungsprofilelemente vorgesehen sind. Die Erfindung betrif ft ferner einen Flachschlassel im Rahmen dieses Profilsystens.
Der Schutz des Lebens, der Privatsphare und des Eigentums stehen an hbchster Stelle. Daher kommt einem Schloss und einem Schltissel eine besondere Bedeutung zu. Bei Schliel~anlagen werden Zutrittsbereiche definiert und durch die Zuordrtung jedes Anlagenschifissels zu einem oder zu mehreren Schl~ssern realisiert. Diese Zuordnung bzw. der Ausschluss von Schitissel und Schloss hinsichtlich der Sperrfunktion wird bei Schlie8anlagen auf der Basis von Schliefzylindern mit Flachschltissein durch das Querschnittsprofil der Schitissel und den Querschnitt des Schifisselkanals erreicht. Nur dann, wenn die Kentur eines Schltisselkanalquerschnitts eineru Flachschlfisselguerschnitt genau entspricht oder diesen einhtUllt, dann passt der Schifissel in das Schloss. Sobald die Kontur des Flachschlfisselquerschnitts jene des Schli-sselkanalquerschnitts schneidet, hat der Schltissel bez~iglich des vorgenannten Schlie~zylinders keine Sperrberechtigung.
Nattirlich gilt diese Zuordnung zwischen Schltissel und Schlie~zylinder Oiber das Profil also den Querschnitt von SchJlissel, insbesondere Flachschltissel und Schitisselkanal des Schliel~zylinders auch far den Einzelzylinder und den Eininclining the blank, grooves can be cut also at an angle to the centre line of the profile cross section, in the form of backed-off grooves.
STATE OF THE ART From DE 31 36 314 Al there is known a key which has ribs extending laterally far beyond imaginary lateral lines of an assumed central cross section, so that this key does not have plane and approximately parallel flat faces. These salient ribs have grooves cut into the direction of motion of the pins. When the salient ribs of the key are filed down, the key can be readily inserted into the key channel and may even effect locking.
A key profile should be configured so that working on it by flat milling does not lead to success.
It is the object of the present invention to substantially overcome or at least ameliorate one or more of the disadvantages of the prior art.
DISCLOSURE OF THE INVENTION Accordingly, in a first aspect, the present invention provides a profile system for defining the cross section of flat keys for lock cylinders with substantially plane and approximately parallel flat faces of the key, a back section of the key and an oppositely situated bit with teeth on the front face for positioning locking pins subdivided into core pins and housing pins spring-loaded in corresponding key channels of cylinder cores against the front face of the bit in the direction toward the back section of the key, wherein grooves cut into the flat sides of the flat key and ribs arranged in the key channel are provided as profile elements of variation and as guiding profile elements, and wherein a branch groove or a branch rib issues from at least one groove in the flat key or, respectively, rib in the key channel, with the direction of plunge-cutting of the latter differing from the direction of plunge-cutting of the groove or, respectively, the rib, wherein the branch groove is provided at a distance from the bottom of a guiding groove in the flat key or, respectively, the branch rib is provided at a distance from the base of the guiding rib.
Lateral scanning of the profile grooves of an original key does not sense the branch groove or senses it only incompletely. The branch groove would have to be produced by reclamping the blank and repeated scanning of the original. Reclamping into an angular position of the center line of the profile groove deviating from the original direction of plunge-cutting of a profile groove necessarily causes lateral shifting so that a branch groove or an additional groove issuing laterally from a groove cannot be produced [R:\LIBLL] 15831 .doc:TCW with proper dimensions, for proper functioning, and at low cost. In practice, this can be done only in the lock-manufacturing plant which has profile reaming machines and large milling centers where clamping alignment errors do not occur because separate error-inducing operations with repeated measurements of an initial position are not required.
Producing branch grooves, which issue from the interior of a groove cut into the flat side of a key, is as difficult as the appropriately matched production of a key channel profile in the lock cylinder. The branch groove or branch grooves advantageously issue from a lateral flank or from the lateral flanks of a groove at a distance from the bottom of the groove. In this way, distinct branching of the grooves into two or more directions is obtained and this branching can hardly be reproduced. In view of the guarantee that this branching groove or branching grooves should always be present in lock systems for safety reasons also in a subordinated key), the groove and branch groove or the rib and the branch rib are conveniently provided as guiding profile elements. In a lock system, the guiding profile is formed on each key so that the desired security is in all cases given. The guiding profile elements are advantageously provided as profile elements having at least one branch groove at a groove or a branch rib at a rib of the guiding profile, with the profile elements configured as oppositely directed, overlapping profile elements issuing from both fiat faces of the key. If an attempt were made to produce a so-to-speak superodinated profile by grinding out the branching groove, the resulting enlargement of the groove would cause weakening of the entire cross section and, in most instances, collapse of the cross section. Thus, there exist restrictions in regard to producing a spare key with the conventional means and unauthorised copying of the key is precluded. It must be noted that the production of a key not corresponding to the original is considered as production of a burglary tool and is punishable by law and that the lock system is degraded by such a key in a manner detrimental to competition. In regard to manufacture or for safety reasons, the plunge-cut width of the branch groove or branch grooves has about one third of the length of the flank or of the bottom of the groove from which the branch groove issues.
In a second aspect, the present invention provides flat keys for a lock cylinder, having substantially plane and approximately parallel flat faces, a back section of the key and an oppositely situated bit with teeth on the front face for positioning locking pins subdivided into core pins and housing pins, wherein from at least one groove of overlapping oppositely directed grooves in the center portion of the cross section of the key bit there issues a further groove as a branch groove at a distance from the bottom of [R:\LIBLL] 15831 .doc:TCW the groove and wherein the direction of plunge-cutting of the groove and of the branch groove are different.
Preferably, the directions of plunge-cutting of the groove and of the branch groove are at variance by approximately 600.
This flat key can be a key of a lock system or an individual key. It is particularly convenient to have the branch groove or the branch grooves issue from the lateral flanks of the groove in the flat key at a distance from the bottom of the groove. Such a key is particularly difficult to produce and, by virtue of the branch groove, weakens the strength of the key to a lesser extent than a groove possibly situated at a lower position in the bottom of the main groove.
BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the object of the invention are shown in the drawings. Figures 1 to 4 show cross sections of keys, Figure 5 shows the cross section of a key channel.
OPTIMAL EMBODIMENT OF THE INVENTION [R:\LIBLL]15831 .doc:TCW WO 03/004806 PCT/AT02/00124 fiber groBe Fr~iszentren verfiiigt, wobei Umspannfehler nicht auftreten, da fehierverursachende separate Arbeitsg~inge mit neuerlichem Verruessen einer Ausgangsposition nicht erforderlich sind.
Die Herstellung von Abzweignuten, die vom Inneren einer von elner Sc'ilflsselflachseite eingeatochenen Nut ausgehen, ist ebenso schwierig, wie die darauf abgestimmte Herstellung des Schltsselkanalprofils im Schliefzylinder. Es ist vortejihaft, wenn die Abzweignut bzw. Abzweignuten von einer Seitenflanke bzw. den Seitenflanken der Nut im Abstand zum Nutengrund ausgehen. Es ergibt sich dadurch eine deutliche Gabelung der Nuten in zwei oder rnehr Richtungen, die kaurn nachgearbeitet werden kann. Irn Hinblick auf eine Garantie, dass diese Abzweignut oder Abzweignuten jedenfalls auch bei Schlief~anlagen aus Sicherheitsgrfinden stets (also auch beim untergeordnetsten Schil~ssel) vorhanden sein sollen, ist es zweckm, iig, wenn Nut und Abzweignut bzw. Rippe und Abzweigrippe als Fihbrungsprofilelemente vorgesehen sind. Das Fflhrungsprofi i st innerhaib einer SchlieBanlage bei jedem Schifissel ausgebildet, sodass somit die angestrebte Sicherheit jedenfalls gegeben ist. Dabei ist es vortelhaft, wenn die Ffhrungsprofilelemente als von beiden Schliisselflachseiten bzw. Schifisselkanaiseitenwanden einander entgegengerichtete tiberlappende Profilelemente mit mindestens einer Abzweignut an elner Nut bzw. Abzweigrippe an einer Rippe des Fiihrungsprofils vorgesehen sind. Wenn man versuchen wolite, ein gewissermaBen OAbergeordnetes Profil durch Ausschleifen der Abzweignut herzustelien, dann wflrde dies infolge Vergrb5Berung der Nut elne Schwdchung des gesamten Querschnitts und in den meisten Fdllen auch das Auseinanderfallen des Querschnitts bewirken. Es sind somit der Herstellung eines Ersatzschliissels mit den gebrauchlichen Mitteln Grenzen gesetzt, die eim unlauteres Schltisselkopieren ausschliefen. Zu beachten ist, dass die Herstellung eines dem Original nicht entsprechenden Schltissels als strafrechtlich verfolgbare Herstellung amnes Einbruchswerkzeuges anzusehen 1st und dass durch amnen solohen WO 03/004806 -PCT/AT02/00124 Schlhlssel in wettbewerbswidriger Weise die Schliefaanlage entwertet wird. Es 1st herstellungstechnisch bzw. aus Sicherheitsgr~nden zweckm,:Aig, wenn die Einstichbreite der Abzweignut bzw. -nuten etwa emn Drittel der Ldnge der Flanke bzw.
des Nutengrundes der Nut betr,'.gt, von welcher die Abzweignut ausgeht. Bin Flachschlflssel mit im Wesentlichen ebenen und annahernd parallelen Flachseiten und mit in diese einschneidenden Nuten ist dacturch qelcennzeichnet, dass von mindestens einer Nut, insbesondere von elnander entgegengerichteten fberlappenden Nuten vorzugsweise im Mittelbereich des Schiiisseibartquerschnittes, eine weitere Nut als Abzweignut ausgeht und dass die Einstechrichtungen von Nut und Abzweignut unterschiedlich sind und beispielsweise urm 60' divergieren. Dieser FiachschlUssel kann emn Anlagenschlissel oder auch emn Emnzelschl~issei sein. Insbesondere ist es zweckm~ffiig, wenn die Abzweignut bzw. Abzweignuten von einer Seitenflanke bzw. den Seitenflanken der Nut im Flachschifissei im Abstand zum Nutengrund ausgehen. Bin soicher Schlhissel 1st besonders schwer herzustelien und schw,.cht durcb die Abzweignut die Festigkeit des Schitissels viel weniger ais eine allenfalls tiefer liegende Nut im Bereich des Nutengrundes der Hauptnut.
KURZE BESCHREIBUNG DER ZEICHNUNGEN Ausfiihrungsbeispiele zum Erfindungsgegenstand sind in den Zeichnungen dargestelit. Fig. 1 bis 4 zeigen Schifisseiquerschnitte, Fig. 5 einen Schl iAsselkanaiquerschnitt.
BESTE AUSFOHP.UNGSFORM DER ERFINDUNG Emn Schhtissel 1 elner Schlie~anlage weist im Querschnitt des Schlifisselbartes etwa in seiner L,-;ngsxnitte emn iberlapptes Fthrungsprofii mit Nuten 2, 3 auf, die jeweils die Profilrnittellinie tberragen. Eine soiche Ausfihrung erftillt die Auf- WO 03/004806 PCT/AT02/00124 6JINJ81 PC/T-/0 gabe eines Ffihrungsprofils, also der Positionierung des Schliissels im Schiasselkanal und deckt die Kernstifte kopfseitig ab, dient also der Abtastsicherheit des Schlie2~zylinders. Von einer Seitenflanke der Nut 2 geht eine Abzweignut 4 als Dreiecknut aus. Die Einstechrichtung (Pfeil 5) zur Herstellung der Nut 2 und die Einstechrichtung (Pfeil 6) der Abzweignut 4 sind unterschiedlich. Somit sind zwei Arbeitsg,-nge und ein Umspannen des Rofilinas f~ir die ge~nderte Bearbeitungsrichtung erforderlich.
Fig. 2 zeigt einen Schitissel 7 und zus~tzlich in der Nut 3 desseiben eine rechteckige Abzweignut 8. In Fig. 5 ist der korrespondierende Schitisselkanal 9 dargesteilt: Dieser weist Rippen 2' und 3' und Abzweigrippen 4' und B' auf. Ein Schlftssel gerna5 Fig. 1 kbnnte infolge fehiender Abzweignut 8 in den Schitisselkanal 9 nicht eingeschoben werden.
Wenn einem Schltisseldienst emn Originalschtissel 7 gemaBT Fig. 2 zur Herstellung eines Ersatzschltissels vorliegen wtirde, dann k6nnten bloZ die Nuten 2 und 3 in der einen Einstechrichuung ausgebildet werden. Woilte man versuchen, durch tieferes Ei'nstechen die Nuten 2 und 3 so auszubilden, dass sie die Abzweignuten 4 und 8 mit umfassen, dann wtirde der SchlLissel 7 auseinanderbrechen. Die Konturen eines tieferen Binstechens sind in Fig. 2 strichliert dargestelit.
In Fig. 3 1st ein Schifissel 10 wiedergegeben, der tiber ein Ftihrungsprof ii gema8 Fig. 1 mit den Nuten 2 und 3 und der Abzweignut 4 hinausgehend noch die Nuten 11, 12 und 13, 13' sowie 14, 14' als Variationsprofil ausgestattet ist. In der Nut 11 ist emn Beispiel fUr ein Variationssystem angegeben.
In Fig. 4 ist emn Schifjssel 15 dargesteilt, der als Ftihrungsprofil die Nuten 2, 3 und die Abzweignut 4 umfasst. In der Nut 16, die, so wie elle anderen nicht gekennzeichneten Nuten, dam Variationsprofii angehbrt, 1st aine Abzwaignut 17 als Tail des Variationsprofiles vorgesehen, die von einer Seitenflanke mit unterschiedlicher Einstechrichtung als Frasers gegentiber der Nut 16 ausgeht. Diese Abzweignut 17 weist amnen butengrund auf, der schr, g zur Ebene der Seitenflanke WO 03/004806 PCT/AT02/00124 der Nut 15 liegt. Dadurch wird emn Nacharbeiten eines Schlissels noch weiter erschwert. Es kbnnen somit nicht nur die Prof ilelernente des Ftihrungsprofils, sondern auch jene des Variationspr-ofils mit Abzweignuten an den Seitenfianken bzw. am Nutengrund bei Rechtecknuten oder Trapeznuten) ausgebildet sein.
Wenn vom Schitissel, den Nuten und der oder den Abzweignuten die Rede war, dann gilt dies sinngemM5 ftr die korrespondierenden Rippen und Abzweigrippen ira Schltisselkanal. Die Ert indung betrifft den Einzeischltissel ebenso wie den Anlagenschitissel, wobei letzterer die Abzweignut in einem Profilbereich aufweist, der bei alien Schitissein der Anlage zwangslaufig vorhanden ist, damit der Sicherheitseffekt bei alien Schitissein in Verbindung mit dem oder den korrespondierenden Schlie1~zylindern gewidhrleistet 1st.
