Definitions

  • the invention relates to a key and a key-lock combination on the Base of locking cylinders with a cylinder core Key channel in which several core pins radially in holes against spring-loaded housing pins from a locked position in a release position by means of the displacement position the pins are determined by notches Flat key are slidable with the notches in the Follow the key bit in a sawtooth fashion.
  • Spare keys or additional copies required should be able to be procured quickly on the one hand, on the other hand it is in the interest of security if only authorized locksmith services after checking the authorization the client are able to use such keys to manufacture. It should be avoided, for example, that a worker copies a copy of his office key procured and thus also after the end of his Has access to the company.
  • Replacement keys are provided by the key services made by copy milling. This will be an original key clamped, the key notches (serration) by means of a sensor in the longitudinal direction of the Key scanned and according to the recorded measured values on a key blank of the same cross-sectional shape transfer.
  • the invention aims to achieve this. the manufacture of replacement or duplicate key through the usual copying process to complicate and thus copying onto those Restrict the circle that is authorized to do so.
  • These key services check the identity of the customer and its authorization to order and take over a spare or additional key.
  • the task is solved by designing the key in this way will that in at least one notch in the longitudinal direction of the Key about in extension of one Key side face spanning the notch Bridge with a contact surface for the core pin it is provided that the bearing surface of the Steges bridges the notch at a depth that is less than the notch depth is that the width of the bearing surface is smaller than the key width and for example is about a quarter of the key width and that the Key-lock combination is designed so that the core pin in the head Cross section is offset and preferably as Circular surface formed a sales area this towering extension surrounds.
  • the core pin is of a stepped design and has an annular heel surface over which a cylindrical or conical extension lying in the axis protrudes. The division is thus a matter of concern the core pin sales surface on the contact surface of the web reached in the notch in the key.
  • the key is copied, then the scanning sensor takes a copy of a copy the contour of the key bit, so that a The key depth is reproduced Position of the contact surface of the original corresponds.
  • the key pin lies with the key reproduced in this way with its extension protruding beyond the sales area at the bottom of the notch and is thus in one position shifted, which protrudes beyond the division area.
  • the core pin thus blocks the locking process.
  • the key copy does not lock, although the key original is the Beard contour after copied correctly.
  • a support surface can be achieved in that as the notch one Key cross-section obliquely V-shaped recess is provided, whose in Key cross-section seen high end the contact surface is flattened.
  • the V-shaped design the notch in longitudinal section at the same time as oblique leads to inclined surfaces along which the core pin slides when the key is inserted. These sloping surfaces offset the core pin in rotation so that its wear is uniform all around he follows. It is useful if the key bit provided in a sawtooth-like manner The notches or edges alternately notch or in different sequences on the left or on the right Show cross-sectional edge The rework will thereby further complicated.
  • FIG. 1 shows one Top view of the narrow side formed with notches a part of a flat key
  • Fig. 2 is a side view
  • FIG. 3 shows a section along the line III-III in Fig. 2, in addition a core pin, a housing pin as well as the division area are indicated.
  • Fig. 4 one Section according to FIG. 3, but through a copied one Key.
  • Fig. 5 a top view of that with another Execution of a notch formed narrow side a flat key
  • Fig. 6 a side view of Fig. 5 and Fig. 7, a section along the line VII-VII in Fig. 6th with an indicated core pin.
  • a flat key 1 for a cylinder lock or a locking system carries notches 2, 3 on his beard V-shaped running surfaces on which core pins a lock cylinder when inserting the Slide key 1 into a key channel until they reach the end position.
  • a surface lying on the notch base the core pins their contact surfaces with spring-loaded housing pins in the division area between the cylinder core and Cylinder housing must be moved by one
  • the notch 3 is one Support surface 5 or a web 5 'on the opposite Edge arranged.
  • the core pin 6 executed separately, that is, it has a ring-shaped Heel area 7 with which he on the support surface 4th sits, the core pin 6 is positioned so that its interface with the associated sprung Housing pin 8 exactly in the division area 9, that is the circumferential surface in the cylinder housing rotatably Cylinder core lies. This can lock the cylinder become.
  • the core pin 6 also carries the sales surface 7 towering extension 10, which in the notch 2 dips.
  • the contour of the key bit as in Fig. 2 is shown by a sensor of a copy router the length as usual in the manufacture of duplicate keys scanned, then the feeler moves in the notches 2, 3 along the contact surfaces 4, 5. It results a copied duplicate key 11, as in the average III-III (Fig. 2) in Fig. 4 is shown.
  • the controlling notch base 12 is in the position of the support surface 4 of the key 1. This is when inserting of the duplicate key 11 in the key channel of the Lock cylinder of the extension 10 of the core pin 6. As a result, the core pin 6 is over the dividing surface 9 postponed and blocked the saving process.
  • FIG. 5 to 7 An alternative embodiment is shown in FIG. 5 to 7.
  • a notch 14 is provided in a key 13, the one with a trapezoidal side milling cutter Contour oblique to the cross-sectional area of the key 13 was incised (Fig. 7). This results in V-shaped and additional against the longitudinal direction inclined inlet surfaces 15, 16 of the notch 14
  • the notch base surface 17 also runs obliquely. She will 7 at its upper end in a second Machined horizontally, so that there is one results in a narrow contact surface 18 or a web (FIG. 5. 7).
  • the Core pin 19 is executed again and carries an annular heel surface 20 with which he on the Bearing surface 18 abuts. Raises above the sales surface 20 an extension 21 in front, which is designed according to FIG. 7 as a cone is.
  • the feeler of a copy router slides along the contour the key bit (Fig. 6), so that a duplicate fails again as shown in Fig. 4.
  • the conical Extension 21 of the core pin 19 is in the Attempt to lock with the duplicate key on the notch base surface (12) and causes incorrect positioning the core pin 19 so that division is not reached. The locking process cannot be done with the duplicate key be carried out.
  • the key 1 or 13 can in the longitudinal direction the flanks with profiling by grooves or ribs be designed as usual with flat keys is.
