Definitions

  • the invention relates to a cylinder lock with pin tumblers which can be brought into the closed position by control surfaces of the associated key, a parting plane of each pin tumbler coming to lie in the parting plane between the cylinder core and the cylinder housing and at least one of the pin tumblers having at least one variation plate which can be moved with the pin tumbler is.
  • Such cylinder locks have been known for a long time and preferably have five or seven pin tumblers in a row.
  • pin tumblers For some purposes it is advantageous and / or necessary to change the variations given by the dimensions of the pin tumblers. For example, When houses are completed, provisionally lock the doors so that construction workers, craftsmen, etc. have access to the individual rooms. When handing it over to the home buyers, all locks have to be laboriously exchanged for the right locks in order to guarantee the home buyers the necessary security against attempts to unlock the door by unauthorized persons.
  • a cylinder lock of the type mentioned in which a recess is provided in the radial plane of at least one pin tumbler in the rotating surface of the cylinder core, said recess being designed to receive the variation plate.
  • FIGS. 9, 10 and 11 show a further exemplary embodiment of the invention, FIG. 9 showing the side view of a key tool, FIG. 10 a section through this key according to XX in FIG. 9 and FIG. 11 represents a section through the cylinder core.
  • a cylinder core 2 is rotatably arranged in the housing 1.
  • a housing pin 5 and core pin 6 are each arranged in housing bores 3 and core bores 4, which act against the pressure of a spring 7 through control surfaces of the key 8 are movable.
  • a variation plate 9 is arranged between the housing pin 5 and the core pin 6, which here has a smaller diameter than the associated pins 5, 6.
  • a recess 11 is provided in the rotary surface 10 of the cylinder core. This recess 11 has at least such a large dimension that the variation plate 9 can be received therein.
  • the key 8 has a so-called. Building key such a depth of cut that the variation plate 9 comes to lie within the cylinder core. So that the division between the housing pin 5 and the variation plate 9 in the rotating surface of the cylinder core, and when rotated in the direction of arrow 12, the lock can be operated like conventional cylinder locks. 2 shows the rotational position in which the housing pin 5 is opposite the recess 11. The smaller diameter of this recess 11 ensures that the housing pin 5 does not snap into the recess and thereby blocks the cylinder core. After a complete rotation of the cylinder core by 360 °, the core pin 6 with the variation plate 9 again lies opposite the housing pin 5, and the key can be removed as usual.
  • FIGS. 1 and 2 show the same rotational positions as in FIGS. 1 and 2, but here not the construction key 8 but the customer key 13 is inserted.
  • This customer key 13 has a smaller incision depth, so that the variation plate 9 comes to rest in the housing 1.
  • the core pin 6 is displaced or turned away from the variation plate until the variation plate engages in the recess 11.
  • the variation plate 9 is taken along by the recess 11 and can always remain there.
  • FIG. 7a-c show a side view of three hierarchically graded keys, with a representing the construction key 8, b a “tradesman key” 14 and c the customer key 13.
  • the incisions 15, 16 are assigned pin tumblers which are equipped with variation plates 9 according to the previous figures.
  • the construction key 8 according to FIG. 7a has two deep incisions 15, 16, and the two associated pin tumblers must therefore each be provided with a variation plate 9.
  • the subsequent craftsmen receive the craftsman key 14 according to FIG. 7b.
  • This has a slightly smaller incision depth at point 15, while the incision 16 is designed in the same way as in the construction key 8.
  • the difference in depth of the incision depths at 15 corresponds exactly to the thickness of the associated variation plate 9.
  • the variation plate is also removed at 16 by catching it in the associated recess in the surface of the cylinder core, as a result of which the final locking variation is produced and the two keys 8, 14 according to FIGS 7a, b are no longer lockable.
  • Fig. 8 the core is shown in side view, in which the keys 8, 13 and 14 fit. As can be seen, the recesses 11 lie in the radial plane of two core bores for the pin tumblers. The associated pin tumblers are assigned the two notches 15, 16 of the key according to FIG. 7.
  • the cylinder lock according to the invention offers the advantage of a very simple and inexpensive construction, it being possible to change the variation without changing the cylinder cores. The change is made simply by inserting the correct key and no additional devices are required. When using a new key, the lock automatically adjusts to the new locking combination.
  • the recesses 11 are designed as an elongated hole. This is advantageous in practice, since the variation plates 9 shown in the drawing can, due to their diameter, which is smaller than the diameter of the pin tumbler, move within the associated core or housing bore and are thus undefined in their axial position. The smaller diameter results in a smaller dimensioning of the recess 11, and the housing pin cannot snap into the recess 11 when it is turned past.
  • the depth of the recesses 11 for the variation plate preferably corresponds exactly to the thickness of the variation plate, so that there is no canting.
  • the recesses can also be arranged deeper. Furthermore, it may be advantageous to fix the platelets in the recesses 11, e.g. by means of adhesive or a press fit.
  • the difference lies primarily in the fact that the laterally arranged recesses 11 in the cylinder core surface according to FIG. 8 are omitted and are replaced by corresponding recesses 17, 18 in the back of the key 19 according to FIG. 9.
  • the key according to FIG. 9 is a special changeover tool for the locking variation of the associated lock. The application is explained below using a hotel locking system.
  • the guest key has the usual appearance of such keys, as shown, for example, in FIG. 7a. If this key is indicated by the guest as lost, for example, or if the guest takes the key with them, it is necessary to change the lock variation of the lock.
  • a changeover key 19 according to FIG. 9 is provided for the change.
  • the incisions on the key bit correspond to those of the new closing variation.
  • the incision milling according to the previous guest key is shown in dashed lines.
  • the key can be removed, the variation plate in the recess 17 being pulled out and thus being removed completely from the lock.
  • the lock is set to the new combination and can only be locked with new guest keys with this changed combination.
  • the variation plate preferably has approximately the same diameter as the pin tumbler. Since the diameter is larger than the width of the spine of the key, a corresponding recess is also provided in the area of the recess 17 in the cylinder core to accommodate the variation plate along the key channel.
  • This recess is preferably a continuous groove 20 in the cylinder core, as can be seen in FIG. 11. The variation plate 9 is also pulled out in this groove when the changeover key 19 is pulled out.
  • the slide 21 is used for this purpose.
  • the slide 21 runs in a groove 22 in the key spine and has essentially the same height as this groove 22 Ren end of the slide 21 has an upward wedge surface 23.
  • the variation of the associated lock is changed so that the slide 21 is pulled out of the area of the recess 17 to the rear.
  • the variation plate is inserted into the recess 17 and the key is thus inserted into the lock.
  • the changeover key 19 is turned through 180 ° until the variation plate is opposite the corresponding housing pin. Then the slide 21 is fully inserted into the key, whereby the variation plate is pushed into the housing bore of the pin tumbler under the action of the wedge surface 23.
  • the change key 19 is turned further, the variation plate remains in the housing bore (position according to FIG. 3) and after a total rotation of 360 °, the change key 19 can be removed, after which the new variation or the previously existing variation is restored.
  • the recess 17 is assigned to the incision milling 23.
  • a further changeover key can be provided, which has the recess at point 18, as shown in broken lines. Accordingly, the variation must also be formed in the incision milling 24 and the associated pin tumbler.
