Definitions
- Lock cylinders in particular for vehicles
- the invention is directed to a locking cylinder of the type specified in the preamble of claim 1.
- the cylinder core rotatably received in the cylinder housing has a profiled axial bore and in the axial bore is a family of turntables arranged one behind the other, which act as tumblers. These turntables are loose and have central openings that determine the key channel.
- the key has radial incisions with defined control shoulders, while the profiled central opening has counter shoulders.
- the turntables have a circular, profiled disk contour with a radial cutout and with a blocking surface delimiting the radial cutout.
- the locking cylinder has an axially parallel, loose, in particular designed as a rolling element locking member, which is always guided with a partial cross section in a radial opening of the hollow cylindrical cylinder core.
- the locking member with a remaining cross-section engages in an axial inner groove of the cylinder housing.
- the locking member is supported radially by the peripheral locking surface of the turntable, whereby twisting of the cylinder core is impossible. If, however, the turntable is moved in the direction of a working rotational position of the cylinder core by actuating the key, the edge is aligned with the locking member for saving the turntable and serves to accommodate the remaining cross section of the locking member, while the inner groove of the cylinder housing is free of the locking member.
- the disadvantage of the known locking cylinder of this type is that it can be transferred from the lock-effective initial rotational position by burglary tools into a working rotational position of the cylinder core, in which, for example, a cylinder equipped with this locking cylinder can be moved without the proper key by so-called "picking ner driving" of the cylinder core Lock can be opened.
- picking ner driving the individual turntables are rotated by a pin until the edge in their disk outlines is aligned with the axially parallel locking member for savings and there is a coupling-effective connection between the turntables and the cylinder core. Then a rotation exerted on the turntables can move the cylinder core and bring it into its working rotational position.
- each of the turntables is provided with a radial nose, which is located between the two legs of a return spring.
- the legs of the return spring pass through two sector-shaped circumferential recesses in the individual turntables. They serve to return the return spring to an initial rotational position, regardless of whether the turntables have been turned clockwise or counterclockwise by the key.
- the return spring requires considerable space in the turntables due to the circumferential sector recesses. With the return spring, the security against tampering cannot be improved compared to the aforementioned picking ner driving.
- the invention has for its object to develop a burglar-proof lock cylinder specified in the preamble of claim 1. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special significance.
- the spring member has an approximately L-shaped axial profile. With its one L-leg, it is in a radial recess in the cylinder core positioned, which is connected to the axial bore of the cylinder core via a radial slot. Through this radial slot the other L-leg of the spring member according to the invention engages radially inwards and is supported there on a shoulder of at least one of the turntables. If you tried to move the turntables using the picking method, you have to do some work against the spring load. As soon as the turntable is released by the intrusion tool, it turns back to its locked position.
- the recess in the cylinder core can be arranged in the peripheral region of the ring-shaped cylinder core.
- the radially inwardly projecting leg can have a very small leg thickness. This results in an extremely space-saving arrangement for the spring member.
- the shoulder for supporting the radial leg from the spring member can advantageously be that radial shoulder of the turntable that serves to take the cylinder core with the key rotation of the turntables.
- the cylinder core has an inner radial counter-shoulder for this entrainment.
- Fig. 1 shows an axial section through the invention
- Fig. 2 is a side view of an associated with the lock cylinder
- Fig. 7 is a subsequent to the key rotation of Fig. 6
- FIG. 8 based on a portion of a modified cylinder core, an alternative embodiment of the lock cylinder shown in Figs. 1 to 7.
- the locking cylinder comprises a cylinder core 10 which is rotatably received in a cylinder housing 20 and has a profiled axial bore 11. This section of the cylinder core 10 is annular. In the cylinder housing 20 there is also a loose locking member 25, which consists of an axially parallel roller 25. In the axial bore 11 of the cylinder core, a family of axially arranged turntables 30 is arranged. Between adjacent turntables 30, an intermediate disk 39 is arranged, which ensures that the individual turntables 30 rotate independently as independently as possible worries.
- the turntables 30 have a profiled central opening 31, which has defined counter shoulders 32 for control shoulders 42 of a key 40.
- the key 40 has a plurality of incisions 43 in its key shaft 41 which, as can be seen from FIG. 3, can be profiled differently from one another and have defined control shoulders 42 to 42 '".
- the key 40 can only be inserted into one in a specific starting rotational position Insert the key channel 21 from the cylinder housing 20, which is then continued from the central openings 31 of the various disks 30.
- the key shaft 41 has a sharpening 44 which, when the key 40 is inserted, clears the way for the key through the central openings 31 of the turntables 30.
- the end section 45 of the key shaft 41 is of non-circular design and is associated with a plug-in receptacle 13 in the cylinder core 10. When the key end section 45 is inserted, there is a rotary drive with the cylinder core 10.
- the key channel 21 is closed by a resilient flap 22.
- the turntable 30 has a circular disk outline 33, but this outline is also profiled. First there is an edge recess 34 which is delimited on the circumference by an adjacent blocking surface 35. When the starting rotational position is present, this locking surface 35 supports the locking member 25 on its outer surface. This applies analogously to all other turntables 30, which have an analog but different profile than FIG. 4 on their disk outline 33.
- the turntable 30 has a sector-shaped recess, one flank of which produces a radial shoulder 36. This radial shoulder 36 is assigned a counter shoulder 16 in the axial bore of the cylinder core. The opposing shoulder 16 is created by the one flank of a ring segment 15 provided in the axial bore 11.
- the cylinder core 10 is stepped in parts on its circumference and has circumferential, radially lowered recesses 12, of which, as shown in FIG. 5, two pieces in this embodiment axial distance from each other.
- the recesses 12 each serve to receive a meandering leg 51 of a U-shaped spring member 50.
- the spring member 50 has a widened U-web 52 which is supported in the region of the radial shoulder 36 of the associated disk 20.
- the U-web 52 creates an inwardly projecting leg which emerges from a radial slot 54 between the recess 12 and the axial bore 11.
- the meandering limbs 51 are resilient in the direction of the limb course and produce an elastic spring elasticity between the cylinder core 10 and the turntable 30. In the initial rotational position of FIG.
- the spring member 50 is essentially relaxed; the radial shoulder 36 on the turntable 30 is loaded as little as the end surface 18 of the recess 12. This only changes when a torque is exerted on the turntable 30 according to FIG. 6 via an intrusion tool (not shown) or via the key 40.
- FIG. 6 shows the initial phase of the disk rotation 37, where the radial shoulder 36 of the disk 30 deflects on the counter shoulder 16 of the cylinder core 10.
- the spring member 50 has compressed to the maximum and exerts a restoring force illustrated by the arrow 38 in FIG. 6.
- Fig. 6 it is assumed that the locking member 25 is still the rotational blockage of the cylinder core 10 compared to the Cylinder housing 20 is produced, although the edge of saving 34 of the disk 30 has more or less already come in radial alignment with the radial opening 14 in the cylinder core 10.
- the cylinder core 10 is finally also rotated in the direction of the arrow 17 of FIG. 7 via the surface contact of the two interacting radial shoulders 36, 16.
- the locking member 25 is pressed out by control surfaces 23 provided on the inner groove 24 of the cylinder housing 20 and dips into the edge recess 34.
- a partial cross section 26 of the locking member 25 is still positioned in the radial opening 40 of the cylinder core 10, but now the locking member 25 with its remaining cross section 27 engages in the edge recess 34. This results in a coupling between the cylinder core 10 and the turntable 30 This causes the cylinder core rotation 17 shown in FIG. According to FIG.
- FIG. 8 shows an alternative embodiment of the cylinder core 10 'with a two-part spring member 50'.
- a first part of the spring member 50 ' is a Slider 28 and the second part is a compression spring 53.
- the other components of this alternative locking cylinder can be designed analogously to the first exemplary embodiment according to FIGS. 1 to 7, they are omitted in FIG. 8; to this extent the previous description applies. It is only sufficient to deal with the differences.
- the compression spring 53 of the spring member 50 ' is formed in FIG. 8 as a flat meander, which is received in a recess 12' of the cylinder core 10 'which extends over the entire meander length.
- the slider 28 is L-shaped.
- the recess 12 ' is covered by one L-leg of the slider 28, while the other radially extending L-leg 29 projects from the slot 54 of the cylinder core 10 into the axial bore 11.
- This radial leg 29 has a Radialfla ke 49 which cooperates in the manner already described with the radial shoulder 36 of the turntable 30, not shown.
- the compression spring 53 is not supported directly, but indirectly via the radial leg 29 of the L slide 28 on the turntable 30.
- the gap between the two cooperating shoulders 36, 16 in the starting rotational position of FIG. 4 is provided at a different location, as the analog heels 16 ', 36' show, namely the radial shoulder 36 'is now on the circumferential L- Leg of the slider 28 and the counter shoulder 16 'on an inner shoulder of the recess 12' there and no longer on the flank of the ring segment 15 'also provided here.
- the ring segment 15 ' is immaterial for the disk rotation 37 described in connection with FIGS. 6 and 7.
- these two shoulders 16 ', 36' are initially at a distance 48 which corresponds to the conditions of FIG. 4.
- the distance 48 from FIG. 8 can be reduced, as described in FIGS. 6 and 7 for the preceding exemplary embodiment.
- Cylinder core (Fig. 1 to 7) 'alternative cylinder core (Fig. 8) axial bore of 10 recess in 10' recess in 10 'socket in 10 for 45 radial opening in 10 ring segment in 11' ring segment at 10 '(Fig. 8) more radially Counter paragraph in 11 'counter paragraph of 10' at 12 '(Fig. 8) cylinder core rotation end face of 12 output member of 10 cylinder housing key channel resilient flap on 20 control surface for 25 in 24 axial inner groove of 20 locking member, roller partial cross section of 25 remaining cross section of 25 slide from 50 '(Fig.
