Definitions
- the invention relates to a lock cylinder for a security lock, with a cylinder housing and at least one cylinder core rotatably mounted in a continuous housing opening, which is inserted into the housing opening from the rear and has a thickening at its rear end, with tumblers which be arranged by a socket wrench that can be inserted into a key channel and with guide means arranged on the rear of the cylinder core for coupling the cylinder core to a driver.
- a lock cylinder of this type is known in the prior art from CH-A-674 542.
- the cylinder core on the outside of the door has a thickening on its rear side, which makes it much more difficult to tear out the cylinder core.
- a self-tapping steel screw is screwed into the outside of the cylinder core and very high tensile forces are exerted on the cylinder core with a pulling device attached to this screw.
- the inventor has set himself the task of creating a locking cylinder of the type mentioned, the tensile strength of which can be individually determined and thus different security requirements can be met.
- the locking cylinder should in particular also meet higher security requirements with regard to tensile strength.
- a locking cylinder of the generic type the object is achieved in that an attachment is arranged on the rear side of the thickening and this has the guide means.
- the coupling part is essentially guided at the rear of the thickening.
- the guide slots for the coupling can thus be incorporated into this approach. This prevents the guide slot from weakening the thickening of the cylinder core, as was previously the case.
- the cylinder core can thus be made substantially more solid, and with a shorter thickening it is possible to achieve the same level of train safety as before.
- the extension can have a smaller diameter than the thickening. This makes it possible for the driver in which the shoulder engages to be formed with a much more stable wall.
- the thickening is embedded in the cylinder housing and / or in an extension piece of the cylinder housing.
- the thickening can not only be made substantially more solid, but at the same time also longer, which further increases the security against pulling off the cylinder core on the outside of the door.
- the area for an individual adaptation to different security requirements is thus further expanded.
- a connecting web is provided which is thickened in the area of the faceplate screw bore, this thickening being wider than a recess for the passage of the driver.
- the thickening of the web can be realized in an advantageous manner by a piece of pipe placed on it. Further advantageous features are the subject of dependent claims.
- Figure 1 schematically shows a partially sectioned
- FIG. 2 shows a partial section through the locking cylinder according to FIG. 1,
- Figure 2a shows a section along the line Ila-IIa
- Figure 3 is a view of the lock cylinder according to
- FIG. 4 shows a view of the rear of a cylinder half
- Figure 5 schematically shows a partially sectioned
- FIGS. 6 and 7 schematically illustrate the core pulling or tearing method
- FIG. 8 shows a view of a connecting web
- Figure 10 shows another view of the connecting web.
- the locking cylinder 1 shown in FIGS. 1 to 4 is a so-called double locking cylinder and has two housing parts 2 and 3, which are fixedly connected to one another with a separately produced connecting web 20.
- the housing parts 2 and 3 each have a continuous, cylindrical housing opening 11, in each of which a cylinder core 4 is mounted.
- At least one cylinder core 4 on the outside of the door is inserted into the housing opening 11 from the rear of the housing part 2 and has a flange-like thickening 13 which engages at least in regions in a corresponding extension 12 of the opening 11.
- the thickening 13 is provided in particular in the case of the cylinder core 4 on the outside of the door, since this is particularly exposed to a violent attempted break-in.
- the other cylinder core can be designed as usual and accordingly inserted into the corresponding housing opening 11 from the front.
- an extension 14 is formed in which a guide slot 25 is incorporated.
- a known coupling part 24 is guided to be longitudinally displaceable.
- This coupling part 24 is used in a manner known per se for coupling the cylinder cores to a driver 15, on which a cam 16 is formed to actuate a lock bolt.
- This Mitneh ⁇ mer 15 is provided with a recess 26 in which the projection 14 engages.
- a socket wrench (not shown here) is inserted into a key channel 5. sets and the coupling part 24 shifted from the position shown in FIG. 2 to the right, after which the cylinder core 4 is coupled to the driver 15.
- the tumblers are arranged by the socket wrench, so that the cylinder core 4 and thus the driver 5 can be rotated.
- this has two blind bores 7 arranged at a distance from one another and a radial slot 8 on its end face.
- a crescent-shaped locking body 9 is inserted, which is held by hardened steel pins 6, which are inserted into the bores 7, in a position in which it engages in a circumferential groove 10 in the inside of the housing opening 11.
- the locking body 9 is slidably guided in the groove 10 and is displaced in the circumferential direction in the groove 10 when the cylinder core 4 is rotated.
- the locking body 9 together with the thickening 13 ensures the exact axial positioning of the cylinder core 4 in the opening 11.
- the locking body 9 When the cylinder core 4 is mounted in the housing part 2, the locking body 9 is completely recessed in the slot 8 and is therefore not on the outside of the cylinder core 4 in front. If the steel pins 6 are inserted into the bores 7, the locking body 9 is displaced outwards and finally engages in the groove 10, as is indicated in FIG. 3. The steel pins 6 fix the locking body 9 and at the same time form a drill protection.
- the locking body 9 is preferably also made of a hard material and forms a further protection against a boring out of the cylinder core 4.
- the two housing parts 2 and 3 are firmly connected to one another by the connecting web 20 shown in more detail in FIGS. 8, 9 and 10.
- the housing parts 2 and 3 each have a recess 21, in each of which an arm 31 engages.
- the arms 31 because a transverse bore 32 is incorporated, into each of which a pin 22 is inserted, which engages in a bore 35 of the housing part 2 or 3 and firmly connects the web 20 to the housing parts 2 and 3.
- the web 20 has a thickening 33 in the center, which is preferably formed by an attached piece of pipe.
- a recess 30 is machined from above on this thickening 33, which enables the driving cam 16 to pass when the locking cylinder 1 is actuated.
- the thickening 33 is substantially wider than the recess 30.
- the thickening 33 is therefore comparatively wide and engages in a shoulder 23 of a cylinder bag 19 at both ends.
- Circumferential shoulders 36 of the thickening 33 each rest on an inside of the housing part 2 or 3.
- the thickening 33 is preferably realized by a piece of pipe which is pushed onto the arms 31 and fixed with cross pins 37. This piece of pipe stabilizes the arms 31, in particular in the area of the faceplate screw bore 29 and effectively prevents the web from breaking during a bending attempt in the area of the faceplate screw bore 29 as a result of material fatigue.
- FIG. 6 schematically illustrates a pull-out test using a steel screw 27.
- This steel screw 27 is screwed into the cylinder core 4 and in the direction of arrow 28 a very high tensile force is exerted on the cylinder core 4 by means of a pulling device, not shown here.
- a pulling out of the cylinder core 4 from the housing part 2 is prevented in particular by the thickening 13, which rests with a shoulder 17 on the back of the housing part 2.
- FIG. 7 illustrates a break in the area of the faceplate screw bore 29 as a result of such an attempt to pull it out.
- bending forces are exerted on the web 20 with the aim of achieving a fatigue fracture.
- the lock cylinder is stabilized by the encompassing thickening 33 and in particular the thickening 33 absorbs bending forces.
- FIG. 5 shows a variant of the locking cylinder 1 according to the invention.
- An extension piece 34 is attached to the rear of the housing part 2 and has a cylindrical passage 38, in which the cylinder core 4 engages with its thickening 13.
- the extension piece 34 extends the housing part 2 in a manner known per se.
- the thickening 13 can simultaneously engage in a corresponding expansion of the housing part 2.
- an extension 14 is formed on the rear side of the thickened portion 13, into which a guide slot 25 for the coupling part 24 is incorporated.
- the slot 25 thus also forms a guide means for the coupling part 24 here.
