Definitions
- the invention relates to a key withdrawal lock for a reversible key, which is insertable into the keyway of a cylinder core rotatably mounted in a lock cylinder housing.
- the pins are movable and are only z. B. held by the spring forces in contact with the key. They also move beyond the dividing plane into the cylinder housing and thus enable the key to be inserted and removed. If the cylinder is rotated in engagement with the appropriate key, the pins move within the cylinder core. Since the axial movement of the pins outside the key withdrawal position is then limited by the wall of the cylinder housing, the key can not be removed due to the positive connection and thus it is ensured that the key can be removed only in the defined position (s) ,
- the object of the invention is to develop a key withdrawal lock, which allows the removal of a reversible key in lock cylinders only in one or more defined positions.
- This object is achieved according to the invention with a key withdrawal lock for a reversible key, which is insertable into the keyway of a cylinder core rotatably mounted in a lock cylinder housing,
- Section in the annular disc corresponds and their position in the axial
- the key is disposed within the key channel such that the rotational path of its axis running in the key shaft axis of symmetry at a distance from the axis of rotation of the cylinder core, wherein the distance, which leads to an eccentricity of rotation of the key relative to the axis of rotation of the cylinder core,
- FIG. 1 shows a schematically illustrated shaft of a reversible key with the trigger lock
- FIGS. 2 and 3 show the key position when rotated by 90 ° or 180 °
- FIG. 4 shows further key positions.
- the individual parts are marked with: 1 ring-shaped disc as a key pull-off barrier
- the key pull lock is formed in the illustrated embodiment as a disc 1 and provided with a groove 3.
- a groove 3 distributed over the inner circumference and a plurality of grooves may be provided, each groove having a
- Recess is located in the 0/360 ° position.
- This groove 3 in the disc 1 is at least one corresponding groove 6 in
- the groove 6 engages in the key shank the disc 1, so that there is a Abziehsperre in this position.
- the key pull lock can be arranged so that the
- the key pull lock can be made of drill resistant materials to provide additional drilling protection
