Abstract (en)

Two diametrically opposed locking bars (18) have relatively offset locking projections (19) so that each tip of an opposing projection reaches into a common plane to enable the lock plug (3) to rotate. The bars have oblique flanks to controllably displace each bar from its locking recess (13,16) in the closing movement. The side profiles of the lock key (4) are made up of arcuate grooves (25) and the crest line of the feeler heads (19) conforms to the groove shape. The displacement plane of the bars (18) is spaced from the diametral plane. The key tip has control ramps in roof shape to issue into the broad sides of the key.

Abstract (de)

Die Erfindung betrifft einen Schließzylinder mit einem in einem Zylindergehäuse (1) drehbar angeordneten, einen Schlüsselkanal (4) aufweisenden Zylinderkern (3), in welchem mit der Schlüssel-Seitenprofilierung zusammenwirkende Sperrelemente (S) quer zur Schlüsselkanalachse verschieblich geführt sind, welche einendseitig mit ihrem Sperrende (17) mit einer Sperrausnehmung des Zylindergehäuses (1) zusammenwirken und welche anderendseitig einen die Schlüssel-Seitenprofilierung abtastenden Tastkopf (19) ausbilden und wobei mindestens zwei in Schlüsseleinsteckrichtung hintereinanderliegende Sperrelemente über einen Steg zu einem Sperrbalken miteinander bewegungsverbunden sind. Zwecks Erzielung einer erhöhten Schließsicherheit schlägt die Erfindung vor, zwei diametral sich gegenüberliegende Sperrbalken (18) mit jeweils versetzt zueinanderliegenden Sperrvorsprüngen (19) vorzusehen, wobei mindestens je eine Spitze der sich gegenüberliegenden Sperrvorsprünge (19) in ihrer eine Kerndrehung ermöglichenden Stellung eine gemeinsame Ebene durchdringen. <IMAGE>
