Definitions

  • the invention relates to a flat key for cylinder lock, the shaft of which has a long profile with longitudinal grooves and / or longitudinal ribs on both flat sides, the long profile of the tip section (tip profile) of the shaft being different from the long profile of the shaft section (shaft profile), and the shaft on Key bit has at least one key notch for the control of a tumbler pin, and the tip profile is slimmer than the shaft profile, so that the tip profile contour lies within the shaft profile contour and a cylinder lock with a housing and a rotatable cylinder core.
  • a well-known post-locking method for cylinder locks is so-called picking.
  • picking There are many tools available for this method, usually a thin plate is inserted into the key channel and the tumbler pins are brought into the release position by vibration. This picking is easier, especially with "open" key channels, since such key channels provide a lot of space for the insertion of the picking tool and its vertical movement.
  • Such open key channels are either system-related or arise in large locking systems through profile variations in which many ribs of the key channel are omitted.
  • An object of the present invention is therefore to design the key profile and the associated lock in such a way that picking is made more difficult. Furthermore, the possibility of creating variations is to be increased so that large locking systems can also be designed.
  • the flat key with the above-mentioned features is characterized in that the at least one key notch is arranged on the key bit in the tip section.
  • the lock according to the invention is characterized in that at least one scanning link is arranged between two of the pin tumblers transversely to the central longitudinal plane of the key channel and that the scanning link has a link profile for scanning the key in its tip section, which is slimmer than the profile of the scanner section of the S ⁇ key channel.
  • FIG. 1 is a side view of a key according to the invention.
  • FIG. 2 shows the top view of a broken cylinder core and
  • FIGS. 3 and 4 show two alternatives for a detail of the cylinder core.
  • FIG. 5 shows a variant of a guide with a key channel cross section according to the invention.
  • FIG. 6 is a cross section through another key channel according to the invention and
  • FIG. 7 shows the associated key in cross section.
  • Fig. 8 is a cross section through the lock and key of another type.
  • Fig. 9 is a section through another type of key.
  • the key 1 has two areas on its shaft 2, namely the shaft section 3 and the tip section 4.
  • the key bit is formed by key notches 5, which can be of different depths in a known manner and with their control surfaces on the control pins 13 Control the associated tumbler pin.
  • the key section 3 carries the key length profile that is necessary for the system and the respective locking variation.
  • This section can have profile elements with relatively large profile ribs 14, to which correspondingly large profile grooves are assigned in the associated key channel. Key profile grooves are designated 15.
  • the profile is formed sctilanker and preferably provided with an overlapped profile.
  • the tip section extends from the key tip 6 to at least behind the area of the first key notch 5 '.
  • Line 16 is drawn in as a dividing line between the two sections.
  • the lowering 23 of the key spine in the tip section which is shown in broken lines, can be designed optionally if a scanning backdrop according to FIG. 4 is used. This lowering represents a further security feature of the key.
  • the key blank is preferably provided with the shaft profile (key profiles 15) over the entire length of the shaft, for example with a profile cutter. Then, in the tip section 4, the profile is made slimmer by removing key material with the formation of additional grooves or expanding existing grooves, as is made clear in FIG. 1 with reference numeral 24. The “slimming down” can go to the limit of material strength, since only a small section of the key is affected and there is no risk of breakage.
  • the tip profile is preferably a profile parent profile.
  • the key profile is scanned by an analog key channel profile of the lock.
  • the key channel profile must in principle allow the entire key shaft to be inserted, that is to say to correspond to the profile of the shaft section 3 and to allow the tip profile to be inserted.
  • a slot 8 is provided for the additional scanning of the leaner (narrower) profiling of the tip section 4 in the cylinder core 7, into which a scanning link 9 is inserted, as is shown in two other exemplary embodiments in view in FIGS. 3 and 4.
  • the link profile 10 defines the tip profile contour and requires an analog profile of the tip section 4 of the flat key.
  • the key channel 11 is pierced by the slot 8 between two pin holes 21 and 21 '. After insertion, the shaft section 3 of the key shaft extends from the collar 22 of the cylinder core 20 to the scanning link 9 in the slot 8.
  • the tip _Ds _z_itt 4 protrudes through the scanning link and uses the key notch 5 'to control the tumbler pin behind it, which in the pin bore 21' sits.
  • the variant Fig. 3 of the scanning backdrop is for key channels open at the top with ⁇ _ ___ ⁇ _ going key spine.
  • the variant in FIG. 4 with a closed branch backdrop requires a lowering 23 at the tip of the key, as shown in broken lines in FIG. 1.
  • FIGS. 5 to 7 show exemplary embodiments for cuts through the key channel or the inserted key with a cutting line along the line V-V in FIG. 2, that is to say somewhat behind the boundary 16 between the sheep section and the - ⁇ itzen section (FIG. 1).
  • the key channel 11 is shown hatched, which shows a certain profile contour shown. This is the shaft - profile contour of the profile of the sheep section 3. As you can see can, the key channel formed in this way is relatively open, so that picking would be possible.
  • a narrower profile contour is formed by the link profile 10 or by the profile parts 17 protruding into the key channel 11, which profile profile lies within the profile contour of the key channel and shaft section.
  • the _ ⁇ itzen section of the key to be inserted thus has to receive a profile which corresponds to this slimmer tip profile contour if the key is to be inserted entirely.
  • the tip section is profiled slimmer, as it corresponds to the backdrop profile.
  • the profile contour of the inner section lies within the profile contour of the sheep section.
  • the entire profile is overlapped over the key height, ie the ribs protruding from both sides into the key channel up to or beyond the central longitudinal plane 12.
  • the insertion of a very thin plate for the picking is possible at most up to the sampling backdrop 9, but not through it. This makes the picking of the tumbler behind.
  • FIG. 6 shows in cross section the key channel 11 of another embodiment of a key with a section through the shaft section.
  • Those additional profile parts 17 which are provided by the scanning link 9 and which make the profile of the tip zenabscfonittes slimmer are shown in broken lines.
  • Fig. 7 shows an associated key in section through the tip section, whereby a narrow profile is given in the tip section. Those additional grooves which have the same key in the shaft section and which give the necessary key variation are shown in broken lines.
  • Fig. 8 shows a cross section through a castle with inserted Key of another profile and tumbler variant.
  • the cutting plane lies on the scanning backdrop 9.
  • the scanning backdrop here serves to cover one of the two halves, namely the right half, of the step-shaped pin tumbler 18.
  • a variation can only take place in the left half shown here, while the right half of the pin tumbler neither from Keys can still be reached by a scanning tool.
  • the key channel from the scanning gate 9 is kept tight.
  • the other right half of the tumbler pins are used for the variations in the areas of the pin holders in front of it, an intrusion tool would have to scan both the right half of all the tumbler pins and the left half of the tumbler pin according to the scanning backdrop 9. In principle, however, this is impossible.
  • 19 denotes the housing, 20 of the cylinder core and 1 of the key.
  • front core pins e.g. with a "right” coding and the innermost core pin with a "left” coding.
  • the left coding of the front core pins is then milled free
  • the front left key encodings and the last right key encoding are not effective.
  • the scanning gate in front of the innermost pin only releases the left half of the profile.
  • the key shaft tip has only the left profile part.
  • the key shaft and the front key channel can also have left and right profile parts.
  • the key-lock system shown in FIG. 8 is described in detail in Austrian patent application A 1847/97 and utility model application GM 681/97.
  • the design of the key profile according to the invention can be used for all profile systems with longitudinal grooves and longitudinal ribs and is not limited to the profile examples shown.
  • FIG. 9 shows the profile quality with another preferred key profile.
  • the cutting plane runs through the tip profile facing the shaft profile.
  • a variant of the shaft profile is shown with strong outer contours, the profile system is shown with thin lines.
  • the shaft profile corresponds to a profile widely used by the applicant, a zigzag-shaped profile being used as the theoretical basic profile. In cross-section, this profile is composed of zigzag-shaped rhombi or rhomboid-like bodies directly adjoining one another. Starting from this zigzag-shaped basic profile, the profile variations are formed in the shaft profile in such a way that a profile element can be arranged over the entire height of a rhombus in the lines 25 shown. In the present case, these are three profile elements a, b and c.
  • the number and arrangement of such profile elements can be freely selected.
  • the shaft profile is not overlapping in this version, i.e. that the groove bases 29 do not reach up to or extend beyond the longitudinal central plane 26.
  • the profile elements (a, b and c) lie one above the other in columns 27, 28 of the profile system.
  • the cut profile 30 shown in section is formed in a zigzag shape by rhombuses lined up, but the tip profile is formed analogously to profile elements a, b and c, with the omission of the variation profile elements. Furthermore, in the illustrated embodiment, the tip profile is formed over the entire height of the key shaft with a smaller wall thickness, so that it is slimmer. In addition, the tip profile is overlapped, which means that the groove bases 29 reach at least as far as the central longitudinal plane 26 or protrude beyond it. In this embodiment according to FIG. 9 is also clearly visible that it is easily possible with the design according to the invention to expand already existing locking systems which are formed with the shaft profile by providing a tip profile according to the invention, with additional protection against picking.
  • the flat key also includes the key blanks, that is to say those primary products which already have the key profile according to the invention and which are provided with the key notches on the key bit only later.
  • the technical features shown in the drawings can also be combined differently.
  • 9 also be conical and have the lowering 23 in the tip section, as a result of which the key height is reduced in this section.
