Definitions
- the invention relates to a turning flat key for a lock cylinder with a fork tip forming key tip having two mutually spaced by a channel control edges for attacking control zones of a core pin of the lock cylinder, wherein the bottom of the channel forms a ramp for the tip of the core pin, each of the two Broad sides of the key shank having a high rib and a parallel thereto arranged Tiefrippe, the ramp is flanked by grooves flanked on both sides of the key key, the high rib of a broadside each opposite a tie rib with oblique walls of the other broadside and the control edges are assigned to the bottoms of the grooves.
- a lock cylinder with a key is known in which the core pins have a flat rib. Side of the flat rib are control slopes, which can attack a flank of a key.
- the key is designed such that it first acts on the control slopes and after a certain displacement only on the flank of the cylinder pin and this completely shifted.
- the flat rib of the core pin is guided in an inlet groove of the key. It is only possible to relocate the pin tumbler to a release position if one has a proper key having the control zone to attack the ramps. Otherwise it is not possible to relocate the pin tumbler to a release position. The pins must not turn.
- a lock cylinder is described with a key whose core pins have a cross-section reduced cylinder portion.
- This cylinder section can tie an unlocking element in the lock cylinder.
- Such an unlocking element which is needed for the percussion method, has deeper cuts than provided for the system. Emerge through the deeper cuts in the unlocking, in the area of the reduced height portion of the tie rib holes. In these holes, the cylinder portion of the core pin can enter and captivate the unlocking. Now it is no longer possible to push the unlocking further into or out again. The lock cylinder is thus protected from the percussion method and can not be opened by this method.
- the core pins and the key are configured as in the aforementioned document.
- the object of the invention is based on the object to improve a generic key closing technology.
- the claim 1 provides that the control edges extend to the oblique walls of the tie rib, they should namely be assigned to the oblique walls latter, so lie at the same height.
- the turning flat key has a key shank whose two broad sides have a high rib and a parallel rib arranged in parallel.
- the high rib of a broadside is assigned in each case a tie rib with oblique walls of the other broadside opposite. Further, it is preferably provided that the high rib projects beyond the key broadside and the channel emanates from the deep rib.
- the run-up slope extends substantially over the entire key thickness.
- the control edges have a rounded shape and, in particular, as well as the control edges rounded concave.
- the control edges and the ramp can have different angles toêtzanitlanguageebene.
- the rib height of the tie rib associated with the bottom of the channel is preferably less than the distance of the top surface of the tie rib to the bottom of a groove adjacent the tie rib.
- the cross-sectional shape of the control flanks is adapted to the control zones of the core pin.
- control flanks are associated with the sloping walls of the tie rib, they already act near a wall of the keyway and can attack the rounded control zones of the core pins.
- the control zones essentially slide off in the line system on the control flanks. These have a rounded shape.
- the tip of at least one core pin forms a cylindrical extension.
- the bottom of the keyway has recesses to the entrance of the tip or the cylin-drical extension of at least one core pin.
- the bottom of the channel forms a ramp for the tip of the core pin. This occurs only after an initial shift by the control edges against the ramp.
- the key is designed as a reversible flat key. A plurality of in the insertion direction of the key one behind the other core pins are arranged in the lock cylinder. One or more core pins form at their tips cylindrical extensions.
- the ramp is associated with a Tiefrippe and a high rib of the key. The ramp extends over substantially the entire key thickness.
- the bottoms of two grooves flanking a high rib are assigned the control edges. These can also be assigned to the oblique walls of a deep rib.
- the control zones and the ramps have different angles to the key channel plane.
- the axial length of the control zones is slightly greater than the rib height of a tie rib associated with the bottom of the channel, but less than the pitch of the top surface of the tie rib to the bottom of a groove adjacent the tie rib.
- a key is provided for a lock cylinder, in which the control edges are rounded.
- Fig. 1 shows a key 1 according to the invention in a perspective view looking towards the key tip.
- the key 1 is designed as a reversible flat key. This forms a key handle 2 and a key shank 3.
- the key shank 3 is profiled and has on each of its broad sides a high rib 4 and a tie bar 5 arranged parallel thereto.
- the profiled key shank 3 is a key channel 11 of a cylinder core 7 form-matched. Since it is a turning flat key, the high rib 4 of the one broad side is compared with a deep rib 5 of the other broad side.
- the raised rib 4 has cone-shaped depressions 6, which are arranged one behind the other in a key-member extension direction.
- the number of reductions 6 is adapted to the number of pin tumblers.
- the sinking depth of the counterbores 6 is dependent on the pin tumblers.
- the deep rib 5 has a step 8. This goes into a reduced height tufa region 5 'over. Before level 8 in the direction of the key tip a countersink 9 is incorporated. In the countersink 9, an additional pin 10 reach into it.
- Fig. 2 the key tip is enlarged in a detail.
- a channel 12 extends starting from the deep rib 5 to the high rib 4 .
- the channel 12 extends at an acute angle from the tie rib 5, in the direction of the key handle 2 to the high rib 4.
- the bottom of the channel 12 forms a ramp 13 for a tip 14 of a core pin 15 or the tip 16 of the cylindrical extension 17 of a core pin 18.
- the ramp 13 is concave rounded and thus the displacement path of the tips 14, 16 form-matched.
- the run-on slope 13 of the tie-bar 5 and also the high-rib 4 is assigned.
- the ramp 13 extends substantially over the entire key shank thickness.
- the key tip forms a fork opening 19. With this fork opening 19, the key tip can project around the cylindrical extension 17 of the core pin 18.

Zur Lösung der Aufgabe sieht der Anspruch 1 vor, dass sich die Steuerflanken bis zu den schrägen Wandungen der Tiefrippe erstrecken, sie sollen nämlich den schrägen Wandungen letzterer zugeordnet sein, also auf der selben Höhe liegen. Der Wendeflachschlüssel besitzt einen Schlüsselschaft, dessen beide Breitseiten eine Hochrippe und eine parallel dazu angeordnete Tiefrippe aufweisen. Der Hochrippe einer Breitseite ist jeweils eine Tiefrippe mit schrägen Wandungen der anderen Breitseite gegenüberliegend zugeordnet. Ferner ist bevorzugt vorgesehen, dass die Hochrippe die Schlüsselbreitseite überragt und der Kanal von der Tiefrippe ausgeht. Ferner sind folgende Weiterbildungen vorgesehen: Die Auflaufschräge erstreckt sich im Wesentlichen über die gesamte Schlüsseldicke. Die Steuerflanken weisen eine gerundete Gestalt auf und sind insbesondere ebenso wie die Steuerflanken konkav gerundet. Die Steuerflanken und die Auflaufschräge können unterschiedliche Winkel zur Schlüsselbreitseitenebene besitzen. Die Rippenhöhe der dem Grund des Kanal zugeordneten Tiefrippe ist bevorzugt geringer als der Abstand der Scheitelfläche der Tiefrippe zum Boden einer der Tiefrippe benachbart liegenden Nut. Im Zusammenspiel mit einem passenden Schließzylinder ist die Querschnittsform der Steuerflanken den Steuerzonen des Kernstiftes formangepasst.To solve the problem, the
Da die Steuerflanken den schrägen Wandungen der Tiefrippe zugeordnet sind, wirken sie bereits nahe einer Wandung des Schlüsselkanals und können an den gerundeten Steuerzonen der Kernstifte angreifen.Since the control flanks are associated with the sloping walls of the tie rib, they already act near a wall of the keyway and can attack the rounded control zones of the core pins.
Die Steuerzonen gleiten im Wesentlichen in Linienanlage an den Steuerflanken ab. Diese weisen eine gerundete Gestalt auf. Die Spitze mindestens eines Kernstiftes bildet einen zylindrischen Fortsatz aus. Der Boden des Schlüsselkanals weist Vertiefungen auf zum Eintritt der Spitze oder des zylin-drischen Fortsatzes des mindestens eines Kernstiftes. Der Grund des Kanals bildet eine Auflaufschräge für die Spitze des Kernstiftes aus. Diese tritt erst nach einer Anfangsverlagerung durch die Steuerflanken gegen die Auflaufschräge. Der Schlüssel ist als Wendeflachschlüssel ausgestaltet. Eine Vielzahl von in Einsteckrichtung des Schlüssels hintereinanderliegender Kernstifte sind in dem Schließzylinder angeordnet. Ein oder mehrere Kernstifte bilden an ihren Spitzen zylindrische Fortsätze aus. Die Auflaufschräge ist einer Tiefrippe sowie einer Hochrippe des Schlüssels zugeordnet. Die Auflaufschräge erstreckt sich über im Wesentlichen die gesamte Schlüsseldicke. Den Böden zweier eine Hochrippe flankierenden Nut sind die Steuerflanken zugeordnet. Diese können auch den schrägen Wandungen einer Tiefrippe zugeordnet sein. Die Steuerzonen und die Auflaufschrägen besitzen unterschiedliche Winkel zur Schlüsselkanalebene. Die axiale Länge der Steuerzonen ist geringfügig größer als die Rippenhöhe einer dem Grund des Kanals zugeordneten Tiefrippe, aber geringer ist als der Abstand der Scheitelfläche der Tiefrippe zum Boden einer der Tiefrippe benachbart liegenden Nut. Des Weiteren ist ein Schlüssel für ein Schließzylinder vorgesehen, bei dem die Steuerflanken gerundet sind.The control zones essentially slide off in the line system on the control flanks. These have a rounded shape. The tip of at least one core pin forms a cylindrical extension. The bottom of the keyway has recesses to the entrance of the tip or the cylin-drical extension of at least one core pin. The bottom of the channel forms a ramp for the tip of the core pin. This occurs only after an initial shift by the control edges against the ramp. The key is designed as a reversible flat key. A plurality of in the insertion direction of the key one behind the other core pins are arranged in the lock cylinder. One or more core pins form at their tips cylindrical extensions. The ramp is associated with a Tiefrippe and a high rib of the key. The ramp extends over substantially the entire key thickness. The bottoms of two grooves flanking a high rib are assigned the control edges. These can also be assigned to the oblique walls of a deep rib. The control zones and the ramps have different angles to the key channel plane. The axial length of the control zones is slightly greater than the rib height of a tie rib associated with the bottom of the channel, but less than the pitch of the top surface of the tie rib to the bottom of a groove adjacent the tie rib.

Seitlich der Hochrippe befindet sich jeweils eine Nut 20. Die beiden Nuten 20 flankieren die Hochrippe 4. Den Böden der Nuten 20 ist jeweils eine Steuerflanke 21 zugeordnet. Somit sind die Steuerflanken 21 auch den schrägen Wandungen der Tiefrippe 5 zugeordnet. Die Steuerflanken 21 weisen eine gerundete Gestalt auf und sind somit der Form der Steuerzonen 22 der Kernstifte 15, 18 formangepasst.Each side of the high rib is a

In dem Zylinderkern 7 sind für die Kernstifte 15, 18 Kernstiftbohrungen 25 vorgesehen. Diese verlaufen in einem rechten Winkel zur Verlaufsrichtung des Schlüsselkanals 11. Die Kernstiftbohrungen 25 sind in der
Die Kernstifte 15, 18 sind rotationssymmetrisch gestaltet. Durch die rotationssymmetrische Gestalt der Kernstifte 15, 18 wird eine kostengünstigere Fertigung erzielt.The core pins 15, 18 are designed rotationally symmetrical. Due to the rotationally symmetrical shape of the core pins 15, 18 a more cost-effective production is achieved.
Die an der Schlüsselspitze eingearbeitete Auflaufschräge 13 und die Steuerflanken 21 können einen unterschiedlichen Winkel zur Schlüsselkanalebene besitzen. Durch unterschiedliche Winkel zueinander wird erreicht, dass sich der Kernstift 15, 18 je nach Winkel unterschiedlich schnell bei gleichbleibender Einsteckgeschwindigkeit des Schlüssels 1 verlagert. Beispielsweise können die Steuerflanken 21 einen spitzeren Winkel zur Schlüsselkanalebene aufweisen als die Auflaufschräge 13. Durch diese Gestaltung wird erreicht, dass am Anfang die Kernstifte 15, 18 langsam verlagert werden und somit ein Verkanten der Kernstifte 15, 18 im Zylinderkern 7 verhindert wird. Gleiten die Kernstifte 15, 18 anschließend auf der Auflaufschräge 13 ab, so verlagern sich diese schneller. In
Es stellt sich folgende Wirkungsweise ein:

Fig. 4 sind die 15, 18 und der Zusatzstift 10 in ihrer Grundstellung.Kernstifte 15, 18 sind Teil einer Zuhaltung, die hier nicht näher dargestellt wird. Zu der Zuhaltung gehören noch Gehäusestifte, die von Federn beaufschlagt werden. Die Federn wirken inDie Kernstifte Richtung des Schlüsselkanals 11. In dieser Position würden dieGehäusestifte den Zylinderkern 7 gegen ein Drehen sichern. Erst durch einen passenden Schlüssel 1 wäre es möglich, die 15, 18 sowie die nicht dargestellten Gehäusestifte derart zu verlagern, dass die Trennebene zwischenKernstifte 15, 18 und den Gehäusestiften mit der Mantelfläche des Zylinderkerns 7 fluchtet. Dann ist es erst möglich, den Zylinderkern zu drehen.den Kernstiften

Fig. 4 are the core pins 15, 18 and theadditional pin 10 in its normal position. The core pins 15, 18 are part of a tumbler, which is not shown here. To the tumbler still include housing pins, which are acted upon by springs. The springs act in the direction of thekey channel 11. In this position, the housing pins would secure thecylinder core 7 against rotation. Only by a matchingkey 1, it would be possible to relocate the core pins 15, 18 and the housing pins, not shown, such that the parting plane between the core pins 15, 18 and the housing pins is aligned with the lateral surface of thecylinder core 7. Then it is only possible to turn the cylinder core.

Wird nun der Schlüssel 1 vollständig in den Schlüsselkanal 11 eingesteckt, verlagern sich die Kernstifte 15, 18 derart, dass jede Spitze 14, 16 in einer passenden Senkung 6 des Schlüsselschaftes 3 einliegt. Der Konusabschnitt 30 des Zusatzstiftes 10 liegt dann in der Senkung 9 der gegenüberliegenden Tiefrippe 5 ein. Werden nun, wie in der
Durch die rotationssymmetrische Gestaltung der Kernstifte 15, 18 wird erreicht, dass diese kostengünstiger hergestellt werden können und die dafür vorgesehenen Kernstiftbohrungen 25 nicht mehr für den Profilquerschnitt der sonstigen Kernstifte angepasst werden muss. Ebenfalls braucht nicht mehr darauf geachtet zu werden, dass die Kernstifte 15, 18 in einer bestimmten Stellung zu den Kernstiftbohrungen 25 eingesetzt werden. Da die Kernstifte 15, 18 keinen Steg mehr ausbilden, sind diese stabiler gestaltet. Durch die Linienanlage der Steuerzonen 22 an den Steuerflanken 21 wird ein geringerer Verschleiß erreicht.Due to the rotationally symmetrical design of the core pins 15, 18 ensures that they can be produced more cheaply and the designated core pin holes 25 no longer needs to be adapted for the profile cross section of the other core pins. It also no longer needs to be taken to ensure that the core pins 15, 18 are inserted in a certain position relative to the core pin bores 25.
