Definitions

  • the invention relates to a key and built-in double cylinder for a security lock according to the preamble of claim 1, with two cylinder halves which are connected to one another, with a cylinder core and with tumblers designed as core pins and housing pins, which can be released for rotation by the key which can be inserted into the key channel of the cylinder core can be classified.
  • Such a key and built-in double cylinder is known from DE-A-3 125 796.
  • a key and built-in double cylinder is also known from the applicant's CH-A-626 679.
  • the two cylinder halves are connected and stiffened with a web made of chrome nickel steel.
  • the cylinder housings of the two cylinder halves consist of firmly connected and strung together Slices. This built-in double cylinder already offers a high level of security against being broken open.
  • the inventor has now set himself the task of increasing security against break-ins.
  • the key has an extension element on its shaft, with which the tumblers can be arranged in an opposite cylinder half to enable rotation.
  • the closing function is also ensured when one cylinder half has no tumblers.
  • the rotor or a rotor half can be made from hardened steel, for example.
  • this cylinder half is usually arranged on the outside. The cylinder half with the tumblers is then on the inside of the door.
  • the hardened steel rotor on the outside of the door protects the tumblers on the inside and would have to be removed in the event of a break-in attempt, for example milled out along its entire length, which would be extremely complex. Since the key extends essentially over the entire length of the double cylinder, no coupling is required, which simplifies production. Since the outer sleeve can be manufactured without tumblers and, as mentioned, no coupling is required, the cylinder can be on the attack side of any door thickness can be adjusted exactly. This prevents the cylinder from protruding on the outside or a rosette having to be attached.
  • the rotor is continuous and provided with a thickened central part.
  • the thickened middle section effectively prevents the rotor from breaking and pulling out.
  • the rotor has an insert which is drilled with a specific drilling pattern. By turning the insert, the number of locking options can easily be doubled.
  • the extension element is movably attached to the key according to claim 13 and can be folded down in a preferred embodiment, so the key can be brought to a customary key length and then does not attach to the key ring.
  • the key is preferably composed of a standard element and the extension element. The key length can then be adjusted to the length of the extension element for each cylinder length.
  • the key can be designed so that it only locks from the outside or from the outside and the inside. As a result, locking competence can be built up more specifically in a security area than before.
  • a corresponding system can in addition to the key according to the invention, also have customary keys with which it can be locked on the inside.
  • FIG. 1 shows a cylinder half 10 with a housing 10a, which has a cylindrical recess 10b for receiving a rotor 21.
  • the rotor 21 consists of hard material, in particular hardened steel, and is equipped with hard metal pins 22.
  • a key guide 24 extends over the entire length of the rotor 21.
  • the rotor 21 is inserted into the opening 10b from the rear of the cylinder half 10 and bears against the housing 10a on the back with a flange 23.
  • a longitudinal groove 18 of the recess 10b slide 17 are inserted, which hold the rotor 21 in the pull-off position under the action of spring elements 19 when the key is removed.
  • the cylinder half 10 preferably has no tumblers and, correspondingly, the rotor 21 has no radial bores.
  • the rotor 21 made of a resistant material could only be milled out with a great effort in the event of a break-in attempt.
  • the flange 23 abuts the housing 10a on the inside, it is not possible to pull the rotor 21 out of the housing 10a from the engagement side.
  • the cylinder half 10 is connected to a web 15 with a second cylinder half 11.
  • the web 15 engages with its two ends in a recess 20 of a cylinder bag 12.
  • the web 15 With cross pins 13, which are inserted in bores 14, the web 15 is firmly connected to the cylinder halves 10 and 11.
  • a threaded bore 16 for a forend screw that fixes the double cylinder in the door lock In a medium thickened Part of the web 15 is a threaded bore 16 for a forend screw that fixes the double cylinder in the door lock.
  • the second cylinder half 11 also has a cylinder housing 11a in which a rotor 27 is mounted. This is fixed on its back with a ring 26.
  • the cylinder half 11 can be constructed as is known per se, i.e. it can have usual tumblers, which can be classified with a conventional key 3 for releasing the rotor 27. After the key 3 has been inserted into the key guide 27a, the rotor 27 and with it the driver 25 can thus be rotated. If, on the other hand, the key 3 is inserted into the key guide 24 of the cylinder half 10, only the rotor 21 can be rotated, which does not take the driver 25 with it. With the key 3, the driver 25 can not be rotated and accordingly a bolt of the lock can not be operated.
  • the double locking cylinder is inserted into a door in such a way that the cylinder half 10 is arranged on the outside and the cylinder half 11 is arranged on the inside. With the key 3, the double locking cylinder can then only be operated from the inside.
  • the keys 1 and 2 shown in FIG. 1 each have an extension element 5 or 7, which is provided with known bores 8 and at the front end of a standard element 4 or 6 is attached. If the key 1 is inserted into the locking cylinder from the outside, the extension element 5 lies in the key guide 27a of the rotor 27 and, with the control surfaces of the bores 8, arranges the tumblers of the cylinder half 11. The rotors 21 and 27 and with this the driver 25 can then be rotated. However, the rotary lock cylinder cannot be actuated from the inside with the key 1, since the standard element 4, which then lies in the rotor 27, has no corresponding bores 8.
  • a locking system can thus have keys 1, 2 and 3 shown in FIG. As explained, the locking options for these three keys are different. This makes it possible to specifically build locking competence in the security area.
  • a locking system usually has several double locking cylinders and many keys.
  • a rotor 30 is provided, which is made of a continuous cylindrical piece of hardened steel. Approximately in the middle, the rotor 30 has a thickening 31, onto which a driver 53 is pushed. The driver 53 engages with a shoulder 53a in a groove 54 of the rotor 30 and is thus rotatably connected to it. Ends 55 and 56 of the rotor each have a recess 36 or 37 for an insert 33 or 32 and are mounted in corresponding recesses 58 and 57 of the cylinder housings 11a and 10a.
  • a key guide 44 extends over the entire length of the rotor 30.
  • the inserts 33 and 32 are drilled according to a specific drilling pattern and receive core pins 35.
  • the cylinder housings 11a and 10a have housing pins, which are not shown here, and which cooperate with the core pins 35 in a known manner.
  • the insert 32 is preferably shorter than the insert 33 and correspondingly the recess 37 is shorter than the recess 36.
  • the end 55 of the rotor 30 is thus substantially more solid than the end 56 and offers high resistance to attack, for example with a milling cutter.
  • a major advantage in addition to the high level of security in the locking cylinder according to FIG. 2 is that the locking options can be doubled by turning the inserts 32 and 33. A significant increase in the number of closings is thus very easily possible without additional manufacturing effort.
  • the housings 10a and 11a can be extended by means of extension elements 28 and 29.
  • An associated key 1 or 2 can be adapted to the corresponding length of the double cylinder in a simple manner, in that the extension element 5 or 7 with the appropriate length will be produced.
  • An adaptation of the standard element 4 or 6 is not necessary.
  • a rotor 38 is provided which only has a recess 41 for an insert 42 on the inside at the end 40.
  • the rotor 38 also has a key channel 44 which extends over its entire length.
  • the other end 39 of the rotor 38 has no bores for tumblers and, with the exception of the key channel 44, is solid.
  • a driver 43 is pushed onto the rotor 38 so that it cannot rotate.
  • a thickened central part 31 is also provided in this rotor, which effectively prevents the rotor from being pulled out of the cylinder housing. Otherwise, the locking cylinder shown in Figure 3 is designed as described above.
  • Figures 4 to 6 show a key 2 with the standard element 6 and the extension element 7.
  • the key can be shortened by pivoting the extension element 7 by a hinge 46, i.e. be brought to the usual length of such a key.
  • the reference number 7a shows the extension element in the working position and the reference number 7b in the folded position. Folding is possible in the directions of the double arrows 52 and 60.
  • the joint has a connecting plate 47, which by means of cross pins 48 with the standard element 6 and the extension element 7 is pivotally connected.
  • Pins 49 which can be displaced to a limited extent, are mounted in stepped bores 51 of the standard element 45 and of the extension element 7.
  • the extension element 7 is fixed in position 7a by the pins 49, but can be pivoted out of this position by a comparatively low transverse force.
  • position 7b the pins 49 rest on side surfaces 47b (FIG. 6) and fix the extension element 7 also in this folded position.
  • the key 2 can thus be brought to a customary key length in a simple manner. The same applies to the key 1 shown in FIG. 1. Designs are also conceivable in which the extension element 7 cannot be pivoted. Finally, versions are possible in which the shaft of the key 2 can be telescopically lowered.
  • FIG. 6 shows a possible arrangement of bores on the shaft of the key 2.
