Definitions
- the invention relates to a locking device which consists of a cylinder lock and a flat key, the cylinder lock being formed from a cylinder housing with a rotatably mounted cylinder core, the cylinder core being provided with a key channel for inserting an associated flat key, and this flat key being equipped with locking notches on its key face, the pin tumblers, which in turn are guided radially in bores of the cylinder core and are located on the longitudinal center plane, are arranged at least one supplementary tumbler, which consists of a side core pin mounted in the cylinder core and a spring-loaded side housing pin provided in the lower part of the cylinder housing, the side and essentially parallel to the longitudinal center plane, the mutually facing ends of these two longitudinally movable pins form a parting line which corresponds to the course of the between the cylinder housing and cylinder NEN formed core twist joint curved and the supplementary tumbler is slidably formed by a movable in a recess transverse to the longitudinal center plane in the cylinder core and
- control element is designed as a spring-loaded, rocker-shaped double lever which extends in the longitudinal direction of the key channel and can be pivoted about a bearing axis running parallel to the longitudinal center plane and transverse to the longitudinal direction of the key channel.
- the double lever has a recess on its underside which is designed as a truncated cone-shaped depression and thus as an active surface for the side core pin having a corresponding counter shape.
- the invention relates to a locking device which secures an automatic anti-rotation / centering of the control chain, side core pin and side housing pin even when the flat key is inserted and removed quickly and does not require any additional components to ensure security against rotation, simple construction, low space requirement, low installation effort and has a high level of functional reliability and can be implemented essentially using standardized components.
- control element is designed as a ball and is arranged in a recess in the form of a bore in the region between the key channel and the side core pin, and the side core pin on its end face facing the ball rises in the direction of the bore Has effective area.
- the advantages of the invention are that the interaction of the control element designed as a ball in conjunction with the end face of the side core pin, which is designed as an increasing active surface, ensures that the side core pin and side housing pin are in position with respect to each other in relation to the congruence between the joint and the core joint.
- the self-centering of the supplementary tumbler elements is permanently present or is automatically restored even when the flat key is inserted or removed quickly by means of a surface-aligning surface contact between the ball and the active surface as well as the mutually facing ends of the side core and side housing pins.
- FIG. 1 shows the locking device according to the invention. This consists of a cylinder lock 1 and a flat key, wherein the cylinder lock 1 is essentially formed from the cylinder housing 2 and the cylinder core 3 rotatably mounted therein. A key channel 4 for inserting the key shaft 5 of the associated flat key is provided in the cylinder core 3.
- the key shaft 5 of the associated flat key is equipped on its key face with variable locking notches 8, which in turn interact when the shaft 5 of the flat key is inserted into the key channel 4 of the cylinder core 3 with the core pins guided in bores of the cylinder core 3 along the longitudinal central plane 7.
- this is done in such a way that the ends of the core pins on the cylinder housing side form a joint joint 22 with the ends of the housing pins on the cylinder core side, which joint then runs along the core joint 9 between the cylinder core 3 and the cylinder housing 2.
- a supplementary tumbler is arranged both on both sides and parallel to the longitudinal center plane 7 (FIG. 1) and in different cross-sectional planes (FIG.
- the supplementary tumbler is actuated by a control element, which is designed as a ball 16 and which is movable in a bore 15 of the cylinder core 3 and which is arranged in the region between the key channel 4 and the side core pin 10, the side core pin 10 on its end face facing the ball 16 17 has an active surface 18 rising in the direction of the bore 15.
- the ball 16 can be controlled by the recess in the side surface 19 of the shaft 5 of the flat key, which is designed as a trough 20 and is variable in depth (FIG. 3), the depth of the trough 20 being coordinated with the likewise variable length of the side core pin 10.
- a stop element designed as a bolt 21 is arranged in the longitudinal direction of the cylinder core 3 in the region of the bores 15 on the cylinder housing side - FIGS. 1 to 3.
- both the housing pins located in different cross-sectional planes along the longitudinal central plane 7 (not visible) and the two additional tumblers arranged on the side of the longitudinal central plane 7 block the rotation of the cylinder core 3 by their side housing pins 12 compared to the cylinder housing 2 in that the joint between the ends of the arranged core pins on the cylinder housing side and the ends of the housing pins (not shown) on the cylinder core side or the separating joint 22 between the ends 13 of the side core pins 10 on the cylinder housing side and the ends 14 of the side housing pins 12 on the cylinder core side by the effect the respectively assigned spring 11 in the lower part 6 of the cylinder housing 2, in an area outside of the existing core joint 9 between the cylinder core 3 and the cylinder housing 2.
- the balls lie 16 in a starting position reaching into the key channel 4.
- the separating joint 22 located between the side core pin 10 and the side housing pin 12 assumes a congruent position with the core twist joint 9 between the cylinder housing 2 and the cylinder core 3 - FIG. 1 -.
- the blockage between the cylinder core 3 and the cylinder housing 2 by the housing pins and also the side housing pins 12 is removed and the cylinder core 3 can be rotated relative to the cylinder housing 2 to actuate the locking device.
- the flat key has been removed, causing the ends of the spring-loaded housing pins and side housing pins 12 on the cylinder core side to move again into the cylinder core 3 (FIG. 2) and thus actively securing its blocking relative to the cylinder housing 2.
- the supplementary tumbler or tumblers in different cross-sectional levels to the pin tumblers not shown in the drawings and arranged in the longitudinal center plane 7, i.e. the supplementary tumbler or tumblers (10, 12, 16) are laterally at a gap between two Adjacent and located on the longitudinal center plane 7 tumblers, which effectively takes into account the limited spatial possibilities on the cylinder core 3 and in the cylinder housing 2.
