Definitions
- the invention relates to a locking device which consists of a There is a cylinder lock and a reversible flat key, with that Cylinder lock from a cylinder housing with a rotatably mounted Cylinder core is formed, the cylinder core with a cylinder housing side open key channel for introducing the associated Reversible flat key is provided and the reversible flat key Wells on two of its opposite sides has different depth, which in turn is guided radially as well as in line on the longitudinal plane and at least from Core pins and spring-loaded housing pins for existing pin tumblers act on which are in alignment with each other Bores of the cylinder housing and the cylinder core added are.
- the disadvantage is that despite the pin tumblers the security against the opening of the locking device as low must be viewed because of the deep graduation of the arranged depressions in the key broadsides by the available material thickness (thickness) of the flat key limited and therefore only small lifting heights of the tumbler pins are realizable.
- the maximum lifting heights of the tumbler pins are due to the key thickness or key channel width are limited because the core pins are limited by the spring-loaded when the flat key is removed from the opposite Hit the flank of the key channel and thus inevitably the housing pins only slightly into the holes of the cylinder core to block its rotation relative to the Cylinder housing protrude so that forceful attempts to break open can be viewed as promising.
- the restrictions regarding depth grading of the depressions exist only a slight permutation achievable so that this solution for both locking systems and locking devices with a greater variety of locking options is only applicable to a limited extent.
- DE 94 18 309 U1 is known from the flat key that can be inserted in a closed key channel symmetrical depressions on its narrow sides (Key chest and back) has the tumbler elements formed as disks (plates) in an inner cylinder held and this in turn rotatable in a cylinder housing is included.
- Such locking devices are liable fundamental disadvantage that they have little security against break-ins have and for the realization of locking systems and locking devices are unsuitable. This is because that such disc tumblers are not like pin tumblers have it divided into several locking levels.
- DE 44 22 093 C2 documents a solution in which the flat key on one of its narrow sides (key face) is equipped with a recess in the form of locking notches. This However, the key cannot be used as a reversible key.
- the invention relates to a locking device of the above type, due to the large lifting heights of the tumbler pins enabled using a reversible flat key and thereby security against break-ins and permutation are increased can.
- the advantages of the invention are that by the both narrow sides (key chest and back) of the reversible flat key shaft recesses in the form of Locking notches and the course of the key channel large lifting heights the tumbler pins (core and housing pins) are made possible, because large sections of the height of the key shaft on both sides available for the realization of the locking notches stand.
- the core pins can also be removed with the reversible flat key no longer hit the flank of the key channel, so that the housing pins far into the holes of the Cylinder core to block its rotation with respect to the cylinder housing can move in and thus against violence Attempts to break out are more resistant.
- the coordinated size relationships between the width of the flanks on the open side of the key channel compared to the dimension of the housing pins ensures that after the introduction of the reversible flat key and subsequent rotation of the cylinder core relative to the cylinder housing when passing through the open side of the key channel the area of the housing pins, not in the key channel can penetrate, so that a permanent functionality of the Locking device can be secured.
- the locking device consists of a cylinder lock 1 and a reversible flat key 2.
- the latter can improve handling in two different positions, i.e. also rotated by 180 °, inserted to actuate the cylinder lock 1 in this become.
- the cylinder lock 1 is essentially from the Cylinder housing 3 and the one rotatably mounted therein about the axis of rotation 22 Cylinder core 4 formed.
- Cylinder core 4 is on the longitudinal plane 5 of the cylinder lock 1 and thus essentially running vertically in the cylinder core 3 and on the cylinder housing side Key channel 6 open on one side for receiving the Key shaft 7 of the associated reversible flat key 2 is provided.
- the longitudinal plane 5 intersects the cylinder housing 3, the axis of rotation 22 of the cylinder core 4 and runs through the key channel 6 and the longitudinal axes of the core and housing pins 11, 12, so that the longitudinal plane 5 congruent with an imaginary longitudinal median plane is designed (Fig. 2 to 5).
- the cylinder lock 1 divided into two halves by this longitudinal median plane.
- the longitudinal plane 5 laterally offset from the longitudinal center plane to run so that this is only the axis of rotation 22 of the cylinder core 3 not integrated.
- the reversible flat key 2 on its two narrow sides, i.e. the key chest 13 and the key back 14, with symmetrically arranged depressions in the shape of variable Provide locking notches 15, which in turn when inserted of the key shaft 7 of the reversible flat key 2 in the Key channel 6 of the cylinder core 4 with the holes 9, 10 of the cylinder core 4 or cylinder housing 3 and also core pins 11 or housing pins guided along the longitudinal plane 5 12 cooperate.
- the pin tumblers lying on the longitudinal plane 5 in the form of the core pins 11 and spring-loaded housing pins 12 are arranged by the locking notches 15 in the key face 13 of the reversible flat key 2 by moving the pins 11, 12 in the direction of the lower part 8 of the cylinder housing 3 in their bores 9, 10.
- the mutually facing ends of the core pins 11 and the housing pins 12 are positioned such that their joints 20 are now in the area of the core joint 21 between the cylinder housing 3 and the cylinder core 4 and thus the rotation blockage of the cylinder core 4 relative to the cylinder housing 3 caused by the housing pins 12 has been lifted (Fig. 2 and 4).
- the key spine 14 reaches the area of the spring-loaded housing pins 12.
- the housing pins 12 penetrate into the open side of the key channel 6 and one associated unwanted re-locking of the locking device, which would also cause an unusable uselessness of this, can be successfully excluded, however, by the fact that the distance (width) 16 between the flanks 17, 18 laterally delimiting the key channel 6 on its open side is smaller compared to the dimension 19 (eg diameter) of the housing pins 12.
