Definitions

the invention relates to a flat key and / or lock cylinder with a cylinder core, which is rotatably mounted in a housing and which has a key channel into which the flat key, which is formed with projections and depressions, for shifting tumblers in one of the key and core-side stop areas Insertion depth is insertable.
Each key for a locking cylinder must be positioned exactly in the key channel so that the key code defined by the key serration (the "key secret") is correctly transferred to the tumblers of the locking cylinder. Stops or stop areas on the key on the one hand and on the cylinder core of the locking cylinder on the other hand serve for exact positioning of the key in the key channel.
the US-PS 4 805 428 shows a cross section through a key-lock combination based on the lock cylinder with profile ribs on the key or in the key channel, which are inclined to the axis direction.
the stop results from the back surface of the key or from a stop surface on the key bow.
the US-PS 4 947 662 relates to an electronic key, from the Reide project electrical contacts that abut ring contacts in the lock cylinder.
the contacts are not stops for the key insert, but could be viewed as key-side protrusions.
a key according to US Pat. No. 5,156,032 has an electrical resistance in the beard area which projects beyond the key on the side. Such projections are not provided in the stop area of the key and do not influence the depth of insertion of the key into the key channel of the lock cylinder.
a key emerges from GB-A-2 072 742, which has a collar in the transition area between reide and beard
the key bit has a gradation, the end face of which rests on a stop surface in the key channel.
key blanks are used, which are pushed into a copy milling machine up to their stop in the transition area between the reed and the shaft, in which the original key is also inserted to control or position the router.
the machine scans the original key and, after the surface profile has been recorded, guides the milling cutter along the key blank, so that a true image of the original is obtained.
copies of minor importance copying can be largely uncontrolled.
the client's authorization must be checked, an exact production and also a special blank that exactly matches the original.
keys of a higher security level can be produced from the technical side by the irresponsible person using the simple key copy milling cutters.
the length of the projections is the same, but preferably greater than the depth of the depressions, and the bottom surface of the depression and the end face of the projection are designed as stop faces.
the actual stop surface is thus at a distance from the end face of the cylinder core. This is not achieved by a copied key.
the copied key therefore does not lock.
the insertion depth of the key shank can be used as a measure that changes from system to system to differentiate between systems with otherwise the same coding (beard configuration).
a specific embodiment of the invention is characterized in that, as is known, a key face aligned radially with respect to the direction of insertion is provided on the key between the key and the key shaft, which extends essentially parallel to the face of the cylinder core when the key is inserted, and that the projection projects axially beyond the face and immersed in an opposite depression and possibly lies against the bottom of the depression. This results in a hook-shaped design of the key in the area of the Reidenauslauf.
a particularly expedient embodiment is characterized in that the projection is designed as an inclined stop surface, for example as a tooth in the reed outlet, inclined towards the key shank and in the cylinder core there is a recess which receives the incline or lies against it or against part of the same.
This tooth has an end flank that is inclined towards the tip of the key.
the depression in the cylinder core receives this tooth, the tooth flanks not touching the inside of the depression in one embodiment, but in another embodiment resting on the depression with part or all of the surface.
a protrusion can also be provided on the core side and a recess on the key side, for example on the reed, which acts to falsify the stop surface during the production of the secondary key.
the projections or depressions on the key shaft and the depressions or projections can be provided in the interior of the key channel. This moves a stop surface that works with the key into the interior of the cylinder core.
FIG. 1 shows a locking cylinder with key according to the invention in cross section
FIG. 2 shows a key copy milling machine in a basic illustration
FIG. 3 shows a variant of FIG. 1
FIG. 4 shows another embodiment of the invention.
a key 1 is inserted in a key channel 2 of a cylinder core 3 of a locking cylinder 4. So that the teeth 5 of the key bit correspond exactly with the core and housing pin tumblers 6, that is, the insertion depth of the key 1 into the key channel 2 to the position of the pin tumblers 6 is precisely matched, each key 1 carries - as is known - a stop 7 which, in the fully inserted state, rests on the end face of the cylinder core 3.
a projection 8 now projects beyond the key-side stop 7.
This projection 8 plunges into a recess 9 without touching the bottom thereof.
the surface which is oriented radially to the direction of insertion of the key and not the projection 8 acts because this disappears without function in the recess.
the key 1 is inserted on the one hand as a pattern or stencil and on the other hand a suitable key blank 11.
a feeler device 12 which guides a milling cutter 13, travels along the toothing 5 of the key 1 and transmits the movements in two axial directions to the milling cutter 13 (for example a disk milling cutter), which produces an exact image of the toothing 5 on the key shaft of the key 11.
FIG. 3 shows a projection 15 on the key 16, which protrudes into a recess 17 in a cylinder core 18 dips and, in contrast to FIG. 1, bears against the bottom of the recess 17.
the end face of the projection 15 and the recessed position of the base (bottom surface) of the recess 17 form the stop of the key 16, which determines the depth of insertion of the key shaft and serves as a reference plane in the production of a replacement key.
the usual key copy milling machine 10 (FIG. 2) is used, a key copy is produced, the key-side stop of which does not interact with the lock-side stop on the base of the recess 17.
the key copy is incorrectly positioned in the key channel.
the key copy does not lock.
Fig. 4 shows an obliquely projecting tooth 19 as a key-side stop, which engages in a recess 20 in the cylinder core 21.
the tip of the tooth 19 rests on the base of the recess 20 and thereby positions the key 22 in the key channel 23.
the recess 20 can also be a true representation of the tooth shape 19, the end tooth flank of which engages the corresponding incline of the recess 20.
the recess 20 can also be larger than the tooth 19, which then engages in the recess 20 without touching it.
the actual stop surface is then outside the tooth e.g. in the transition area between tooth and key shank.
the effective stop determining the insertion depth of the key in the key channel can also be moved into the key channel.
a rib arranged on the side of the flat key can start from the end of the key on the stem side and end with a stop surface at half the length of the key shaft. This strikes a stop surface on the side in the key channel.
the otherwise usual stop in the area of the reed spout is ineffective and takes up a distance from the end face of the cylinder core when the key is inserted. Since the key copy is based on this ineffective or apparent stop, the copied key is inserted too deep into the key channel. The key does not work.
the lateral profile rib or an axial groove in the flat key which begins at the key tip in the area of the key shaft and which works together with a projection in the key channel as a stop, moves the stop forward from the usual stop area.
the key copy milling machine cannot follow this transformation. The result is unusable.
Anyone ordering a replacement key must contact the lock manufacturer or their regional representative to obtain a suitable key.
the lock manufacturer is very interested in granting the buyer's authorization e.g. to be checked using a security certificate. For some key services, on the other hand, only sales count. Questions about authorization unfortunately recede as long as the key can be easily copied by the locksmith. In this sense, the invention takes into account the individual security needs of the general public.
