Definitions

  • the invention relates to a cylinder lock with at least one locking body secured against rotation and at least one cylinder body rotatable about an axis of rotation by means of a key relative to the locking body, and with a rotatably mounted anti-drilling device.
  • Cylinder locks without a drill safety device can be broken open relatively easily by drilling the cylinder body, which is usually made of brass, from the outside of the cylinder lock, cutting a thread and pulling the cylinder body out of the lock using a mechanical or hydraulic pulling device, similar to a cork a bottle, the door surface surrounding the lock being used as an abutment for the pulling device.
  • a protective rosette on the outside of the cylinder lock, in which a cover plate made of steel or similar resistant material is mounted in a holder projecting forward over a door surface that is a penetration of a drill prevented in the cylinder body behind.
  • the cover disk which is provided with a slot for inserting the key, is rotatably mounted about the axis of rotation of the cylinder lock by means of a ball bearing, so that it can rotate when the key is turned.
  • a protective rosette protruding outwards beyond the door surface offers too many contact surfaces for burglary tools, so that adequate protection against prying open or twisting off is not provided.
  • the rotatable cover plate can be easily locked by blocking the ball bearing with quick-setting cement or synthetic resin, whereupon the slot can serve as a guide for a drilling tool, so that, despite the resistant material, drilling of the lock through the relatively thin cover plate is possible.
  • the object of the invention is to improve a cylinder lock of the type mentioned at the outset in such a way that drilling is reliably prevented without devices protruding outward beyond an end face of the cylinder lock.
  • the anti-drilling device is arranged within the cylinder lock.
  • the invention is based on the idea that an anti-drilling device rotatably mounted within the cylinder lock on the one hand rotates when a drill is placed on it and thus prevents the same from penetrating and on the other hand can be formed essentially flush with the end face of the cylinder lock so that it can attack one Burglar tool only presents its front face.
  • At least one cylinder body arranged on the outside of the cylinder lock is penetrated by the anti-drilling device arranged concentrically to the axis of rotation.
  • the anti-drilling device arranged concentrically to the axis of rotation.
  • the rotatably mounted anti-drilling device expediently extends through the locking body and the two cylinder bodies, so that their end faces are each flush with the end face of the cylinder body.
  • a further advantageous embodiment of the invention provides that the anti-drilling device is held immovably in the cylinder lock in the axial direction.
  • a further advantageous embodiment of the invention provides that the anti-drilling device is supported against a shoulder facing the outside of the castle, which according to a further advantageous one Embodiment of the invention can be formed by a circumferential annular shoulder of a central bore formed as a stepped bore of the cylinder lock.
  • the anti-drilling device is advantageously made of hardened steel so that it also resists attack by hard metal drills if a burglar succeeds in blocking the rotation of the anti-drilling device.
  • the cylinder lock To assemble the cylinder lock, it expediently has a locking pin, which can be inserted into a radial ring groove of the anti-drilling device, and which, after inserting the anti-drilling device into the stepped bore through the cylinder lock, is screwed into a threaded bore opening into the ring groove until it is screwed into the ring groove intervenes.
  • the anti-drilling device penetrating the cylinder lock in the center can be most easily realized in that the cylinder body and the locking body are arranged one behind the other in the direction of the axis of rotation, and in that the cylinder body and the locking body each have aligned recesses in which the under the action of at least one compression spring tumblers are longitudinally displaceable, of which at least a part passes through at least one separating surface arranged between the locking body and the cylinder body when the lock is locked.
  • the tumblers can be arranged in a cylindrical shape around the axis of rotation, so that space is created between them for the anti-drilling device concentric with the axis of rotation.
  • a further advantageous embodiment of the invention provides that the cylinder lock and preferably also the key can be reversibly coded, so that e.g. if a key is lost or stolen, the lock can be recoded and the remaining keys can be adapted to the new coding of the lock without the need for a specialist company.
  • the double cylinder lock 1 shown in the drawing consists essentially of a locking body 6 secured in the lock case 4 against rotation, two cylinder bodies 12, 14 rotatable by means of a key 8 relative to the locking body 6 about an axial axis of rotation 10, and a plurality of tumblers 16a, 16b are arranged so as to be displaceable in a ring-shaped arrangement around the axis of rotation 10, the locking body 6 and the cylinder body 12, 14 are displaceable in the axial direction, as well as a drilling security device 24 inserted in a continuous central stepped bore 22 of the cylinder lock 1.
  • the locking body 6 has the shape of a disk 26 which is penetrated in the axial direction by the recesses 20 and the stepped bore 22 and over whose cylindrical peripheral surface 28 a comb 30 with a cylindrical peripheral surface 32 protrudes, which in the axial direction by annular shoulders 34 with respect to the peripheral surface 28 of the disc 26 is deposited.
  • the comb 30 has two diametrically opposite recesses 36, 38 arranged laterally in the lock case 4 in the installed state, the up and down are limited by parallel guide surfaces 40.
  • the cylinder bodies 12 and 14, each bearing against an end face 42 or 44 of the locking body 6, are essentially cylindrical in shape and have indentations 46, 48 on their ends facing the locking body, each of which has an edge projecting axially from an end face 50, 52 53,57 are limited, the inner and axial boundary surfaces bear against the annular shoulders 34 of the locking body.
  • the recesses 20 are formed as stepped bores 54, which are introduced from the end face 50, wherein a compression spring 56 is inserted into the recesses 20, which is in the direction of an axial end face 58 of the cylinder body 12 against an annular shoulder 62 of the stepped bore 54 supports.
  • the cylinder body 14 is, in contrast, formed in two parts, the compression springs 56 are each inserted into a bore 61 of a receiving part 59 facing the locking body 6 and are supported against an end face 63 of a cap-shaped end part 65 which is placed on the receiving part 59 and on this by grub screws 67 is held, which are screwed from the outside into threaded bores of the end part 65 and engage in radial bores of the receiving part 59.
  • the tumblers 16a, 16b inserted into the recesses 20 against the force of the compression springs 56 in the axial direction so as to be displaceable on the two sides each consist of two actuating pins 64a, 64b, between the facing ends 66 of which one or two locking cores are optionally available 68 are loosely inserted.
  • the actuating pins 64a, 64b each have a head part 72, which is displaceably guided in the enlarged part of the stepped bore 54 of the cylinder body 12 or in the bore 61 of the receiving part 59, is supported against the compression spring 56 and bears against a locking core 68, and one in an unloaded state Predetermined dimension over the axial end faces 58, 60 of the cylinder body 12, 14 projecting actuating part 74, which is slidably guided in the narrower part of the stepped bore 54 or in a bore 55 of the end part 65.
  • the cylindrical locking cores 68 all have the same length and are delimited in the axial direction by radial end faces 70 which bear against the head parts 72 of the actuating pins 64a, 64b or against the end face 70 of the further locking core 68.
  • the outer edge of the end face 70 is chamfered in each case in order to facilitate the insertion of the locking core 68 into the recess 20.
  • All tumblers 16a, 16b have the same overall length, which is ensured by the fact that the actuating pins 64a of the tumblers 16a, which have only one locking core 68, are longer than the actuating pins 64b of the tumblers 16b with two locking cores 68.
  • tumblers 16b which have two locking cores 68, when the cylinder lock 1 is locked, they are arranged in the unloaded state in such a way that they each pass through one of the two separating surfaces 76, 78, which lie between the end faces 42, 44 of the locking body 6 and against the end faces 42,44 adjacent end faces 50,52 of the cylinder body 12,14 are formed, which are rotated against each other when the cylinder lock 1 is opened.
  • the tumblers 16a which have only one locking core 68
  • the locking cores 68 are arranged in the unloaded state when the cylinder lock 1 is locked so that their end faces 70 are aligned with the separating surfaces 76, 78.
  • the tumblers 16b with the Keys 8 are shifted until the end faces 70 of one of the two locking cores 68 are also aligned with the separating surfaces 76, 78.
  • the tumblers 16a must not be displaced, since otherwise their locking core 68 would penetrate one of the two separating surfaces 76, 78 and would thus prevent the cylinder lock 1 from opening.
  • the cylinder bodies 12, 14 each have a transport toothing 82 designed as an involute toothing, which engages in a correspondingly designed toothed rack 84 of a bolt 86 which can be displaced in the lock case 4 such that the bolt 86 when the cylinder body 12, 14 inserted key 8 is withdrawn in a clockwise direction, while it is pushed out of the lock case 4 when turning counterclockwise.
  • the transport teeth 82 arranged in the area of the edges 53, 57 projecting axially beyond the end faces 50, 52 are each molded into the cylinder bodies 12, 14 only on a partial circumference thereof.
  • the two cylinder bodies 12, 14 and the locking body 6 are held together by the anti-drilling device 24, which rests in the cylinder body 12 with a circumferential ring shoulder 88 against an annular shoulder 90 of the stepped bore 22, while in the cylinder body 14 of two diametrically opposed ones in radial bores 96 Cylinder body 14 inserted locking pins 92 is held, which engage in the radial direction from the outside in an annular groove 94 of the anti-drilling device 24.
  • the locking pins 92 held in each case by a grub screw 98 in the radial bores 96 have the effect that the anti-drilling device 24 made of steel is rotatable and axially immovable relative to the cylinder bodies 12, 14 and the locking body 6, so that a drill bit which is on one of the end faces 58,60 aligned end faces of the anti-drilling device 24 is placed, this is rotated at the same rotational speed and thus cannot penetrate into it.
  • the locking pins 92 and the grub screws 98 in Figures 1 and 2 are shown in one plane with a pair of tumblers 16a, 16b; in practice, on the other hand, the radial bores 96 run between two adjacent tumblers 16.
  • the anti-drilling device 24 in particular in the case of single-cylinder locks but also in the case of double-cylinder locks, can be arranged on the outward-facing end face of the cylinder lock in such a way that it is supported with its opposite end face inside the cylinder lock.
  • the anti-drilling device 24 can, for example, be releasably inserted into an end blind bore in the cylinder body in accordance with the exemplary embodiment shown.
  • the key 8 for opening and closing the cylinder lock 1 essentially consists of a cylindrical disk 100 facing the end surface 58, 60 of the cylinder lock 1, which is arranged in a ring shape and corresponds in its position to the position of the actuating pins 64a, 64b projecting beyond the end surface 58, 60 has continuous axial bores 102 for the engagement of the actuating pins 64a, 64b.
  • the bores 102 have a length corresponding to half the length of the locking cores 68 and are chamfered on the end face 126 of the disk 100 facing the cylinder lock 1 in order to facilitate the insertion of the actuating pins 64a, 64b when the key 8 is inserted.
  • Stepped bores 112 are made in the actuating disk 108 from its end face 106, the longitudinal axes 114 of which are offset in the radial direction relative to the longitudinal axes 116 of the bores 102 by the radius of the bores 102.
  • Adjusting bolts 118 are rotatably inserted in the stepped bores 112, the ends 120 of which are directed towards the end faces 58, 60 of the cylinder body 12, 14 and each have two semicircular end faces 122, 124 corresponding to half the cross-sectional area of the adjusting bolt 118, each of which corresponds to half the cross-sectional area the actuating pins 64a, 64b arranged in the extension of the bore 102 serve as a stop surface.
  • the adjusting bolts 118 have 128 slots 136 on their end faces facing away from the cylinder lock 1 and projecting slightly beyond the end face 132 of the key 8 for the engagement of a screwdriver.
  • the peripheral surface 134 of the actuating disk 108 is roughened. A marking 140 made on the peripheral surface 134 ensures that the key 8 has the correct rotational position when it is inserted.
