Abstract
Description
Die Erfindung betrifft einen Zylinderkern welcher für Rund-, Oval und Profil-Schließ-Zylinder, aber auch Blockschlösser nach den Merkmalen des Oberbegriffes des Anspruches 1 verwendet werden können.The invention relates to a cylinder core which for round, oval and profile lock cylinders, but also block locks according to the Features of the preamble of claim 1 can be used.
Bis heute werden Zylinderkerne für Schließ-Zylinder aus Messing oder vergleichbar weichem, leicht verarbeitbarem Material hergestellt.To date, cylinder cores for lock cylinders are made of brass or comparable soft, easy to process material.
Die Grundform des Zylinderkerns entspricht der Fig. 1.The basic shape of the cylinder core corresponds to FIG. 1.
Der Zylinderkern bildet ein massives Rundprofil welches durch Bear beitung aus gezogenem oder auch gegossenem Material gefertigt wird.The cylinder core forms a solid round profile which is created by Bear processing is made of drawn or cast material.
In der Längsachse wird durch das Rundprofil mittels Ziehwerkzeug ein Schließkanal 2 für die Einführung des Schlüssels eingebracht. Die Profilierung erfolgt in der Regel nach DIN 18252 Pos. 2.6. Die Querbohrungen 3 dienen der Aufnahme von Zuhaltestiften, welche in der Anordnung und Anzahl variabel sind. Ebenso variabel sind der Schließ bartanschluß 4 oder die Stirnseite 5 durch Form und auch der Einsatz der für den Bohrschutz erforderlichen Stahlstifte 6.A locking channel 2 for the insertion of the key is introduced in the longitudinal axis through the round profile by means of a drawing tool. Profiling is usually carried out in accordance with DIN 18252 item 2.6. The transverse bores 3 serve to hold locking pins which are variable in arrangement and number. The closing beard connection 4 or the end face 5 are also variable by shape and also the use of the steel pins 6 required for the drilling protection.
Das bei praktisch allen Schließ-Zylindern verwendete Material Messing, oder vergleichbar weichem Material ist aber verhältnismäßig leicht auf brechbar.The material brass used in practically all locking cylinders, or comparable soft material is relatively easy breakable.
Aufgabe der Erfindung ist es daher, einen Zylinderkern der eingangs genannten Art zu schaffen, der gleichwohl aus einem Material hergestellt werden kann, welches gegenüber Messing oder vergleichbarem Material er heblich schwerer zu bearbeiten ist.The object of the invention is therefore a cylinder core of the beginning to create the type mentioned, which is nevertheless made of one material can be compared to brass or comparable material is considerably more difficult to process.
Dadurch, daß bevorzugter Weise nichtrostender Stahl oder ein anderes, schwer bearbeitbares Material verwendet werden kann, ist auch der sog. Widerstandszeitwert, also diejenige Zeit, die benötigt wird, den Schließ- Zylinder aufzubrechen, gegenüber dem aus Messing oder vergleichbarem Material, erheblich vergrößert bzw. verlängert. Dadurch ergeben sich erhebliche Sicherheitsverbesserungen für den Schließ-Zylinder.Because preferably stainless steel or another, material that is difficult to process can also be used. Resistance time value, i.e. the time required to close the Break open cylinder, compared to that of brass or similar Material, significantly enlarged or extended. This results in significant security improvements for the locking cylinder.
Durch den Einsatz von nichtrostendem Stahl, welcher sich durch die Qualität hoher Härte und Zähigkeit auszeichnen muß, können die Bohr stifte 6 entfallen.Through the use of stainless steel, which must be characterized by the quality of high hardness and toughness, the drilling pins 6 can be omitted.
Die Stahlqualität erfordert aber insbesondere für die Einbringung des Schließkanals hochwertige wirtschaftlich interessante Werkzeugmaschinen.The steel quality, however, requires especially for the introduction of the Locking channel high-quality economically interesting machine tools.
Eine Möglichkeit ergibt sich z. B. durch die Funkenerosions-Werkzeug maschinen neuester Bauart mit 3-D-Erodiereinrichtungen und frei pro grammierbarer Positioniersteuerung welche auch für die Serienfertigung wirtschaftlich interessant wurden.One possibility arises, for. B. by the spark erosion tool machines of the latest design with 3-D eroding devices and free pro programmable positioning control which also for series production became economically interesting.
Diese oder ähnliche Maschinenarten bieten weitere Verkomplizierungen des Schließkanals 2 durch Formgebung und Anordnung im Zylinderkern Der Zylinderkern kann zur besseren Gleitung mit einem Oberflächen schutz versehen werden. Dadurch gekennzeichnet, daß zwischen dem nicht rostendem harten, zähen Stahl und dem Gehäusewerkstoff der für die Gleitung optimale Schutz gewählt wird.These or similar types of machines further complicate the closing channel 2 by means of shape and arrangement in the cylinder core. The cylinder core can be provided with a surface protection for better sliding. Characterized in that between the rustproof hard, tough steel and the housing material the optimal protection is chosen for the sliding.
