Definitions

the invention relates to a lock and key system, comprising a lock cylinder housing with a cylinder core rotatably mounted therein, in the key channel of a flat key is inserted, which has on its flat side a coding which is detectable in the lock cylinder, .appeli if not matching coding in the Cylinder core mounted locking element on the parting plane cylinder core / lock cylinder housing is displaceable in a recess in the lock cylinder housing, thus preventing the rotation of the cylinder core.
the flat key has notches on the key-breast, which are scanned by core and housing pins, which, with the key matching at the parting plane, align cylinder-barrel locking cylinder housings so that a closing operation can be performed. Further profilings are provided in the side surfaces of the key shank, which are checked on the one hand by the corresponding design of the key channel and on the other hand by additional sensing elements in the cylinder core and. Both the notches as well as the profiling one speaks of the coding of the key.
Simple keys can be easily scanned and made on a digital copying machine or in other stereolithography systems. Key cards and other credentials for copying e.g. Master keys for locking systems can be easily bypassed.
the invention has for its object to provide a key-copy protection, which further complicates the copying of the key on digital copying devices.
a query element or interrogation pin is provided in the cylinder core, which detects the presence of at least one ring and prevents rotation of the cylinder core in the absence of the rings.
two rings are arranged, which can be moved laterally, ie transversely to the key shaft longitudinal plane.
the rings are fixed in the key by an axle located in the key shank longitudinal plane.
In the cylinder core is a corresponding eviction to introduce the key with rings.
the rings can be moved in semicircular pockets in the cylinder core. This shift is made by two sliders, which sit with their noses in the labyrinth grooves of the lock cylinder housing. Due to the core rotation, the slides move in the direction of the center of the cylinder core and move the rings in the opposite direction. One slider moves the lower ring, the other the upper ring.
the slides have different recesses into which the rings can dip.
the slides move the rings into the key shank. This is to ensure that with copied keys without rings (only a "window” in the key), the key can not be pulled out after closing because both slides block the key.
rounded edges on the recesses in the cylinder core ensure alignment of the rings and resetting of the two slides.
the sliding elements could be made sluggish via spring-loaded balls to prevent the closing of duplicate plastic keys (the rings would deform and hinder the removal of the key).
the system according to the invention is also suitable for reversible key systems.
FIG. 1 shows the not fully imported key 1, the lock cylinder housing 3, and the cylinder core. 2
FIG. 2 shows the cylinder housing 2 rotatably mounted in the lock cylinder housing and the key 1.
a recess 8 ( FIG. 3 ) of the key shank are arranged one above the other two rings 4, wherein the fixing is effected by a common axis 10 which is arranged in the key shank longitudinal plane. Both rings 4 can move separately or together across the key shaft.
a corresponding evacuation is provided in the cylinder core, which is denoted by 7. If the key is completely inserted into the keyway, the rings (not shown here) are in extensions of the cylinder core and act there with Spertiatan, which are designed as a slide 6, together.
FIG. 2 2a shows the fully inserted key and the slides 5 and 6 moved during the core rotation, in which the rings 4 dip into corresponding recesses 11 in the slides 5 and 6.
the edge 12 of the slider moves the ring into the recess 11 of the opposite slider and partially immersed in the recess in the key shank.
the lugs 14 of the slides 5 are located within the cylinder core circumference, ie below the parting plane, so that the cylinder core can be rotated to carry out a closing operation.
FIG. 3a shows the mounting of the rings 4 on the common axis 10 in the key shank
FIG. 2b showing the arrangement of a stylus 15 in the cylinder core.
This pin scans the presence of at least one ring 4 and is pressed upon rotation of the cylinder core of the ring 4 to the parting plane. If the ring is missing completely or if it does not have the correct diameter, then the normal housing pin 17 - after half a turn of the cylinder core - can plunge into the bore of the stylus 15 and thus prevent further rotation of the cylinder core.
