Definitions

  • the invention relates to a flat key for a Cylinder lock, and with a flat key and associated cylinder locks a profile arrangement such that the flat key longitudinal ribs and / or on the key flat sides Has longitudinal grooves in the direction of insertion of the key run into the key channel, in addition to the Longitudinal ribs and / or longitudinal grooves inclined profile grooves are provided are at least one of the longitudinal ribs or grooves to cut.
  • the subject invention is characterized in that that at least one on each of the key flat sides Inclined profile groove is provided, the inclined profile grooves of the two flat sides of a key or whose extension line cross each other in space that the key in the incision area of the key face has at least four longitudinal grooves, each of the central longitudinal plane tower and that in the area of the key back at least one longitudinal groove is provided, the bottom of the profile groove with the circular arc in the preferred manner Profile groove base of the oblique profile groove (s) coincides.
  • the lowest and the uppermost of the at least are preferred 4 longitudinal grooves in the incision area for the formation of Locking systems did not vary, while the two middle ones Longitudinal grooves are variable in terms of location and arrangement.
  • the angled profile grooves on each key flat side can be used be arranged in two groups, each Group for the formation of variations, preferably 5 control points and thus have a maximum of 5 inclined profile grooves. This results in a total of 20 control points for the variation.
  • FIG. 1 shows the side view of a key according to the invention.
  • Fig. 2 shows schematically a preferred embodiment of the profile system and
  • Figs. 3 and 4 show two embodiments for profiles according to the invention.
  • 5, 6 and 7 are cross sections through a cylinder lock with inserted Key and
  • FIGS. 8 to 11 show the key laterally scanning organs.
  • the flat key 1 comprises the key shaft 2 and the Reide 3.
  • the height of the key shaft is composed of the incision area 4 and the Back area 5.
  • Each of the key flat sides 6 has two Types of Profiling on. First, there is a conventional one Longitudinal profiling in the direction of insertion of the key. In Fig. 1 this longitudinal profile is on one key flat side through the given three longitudinal grooves 7.
  • the incision area 4 described above is the area in which the incisions from the key chest 38 11 are sufficient to control tumblers can.
  • each of the five shown Incisions 11 have ten different depths of variation (see also Fig. 4).
  • the longitudinal profile grooves 12 and 15 are within a profile series always the same in terms of location and shape, while the longitudinal profile grooves 13 and 14 in their arrangement are variable according to the situation, as further below is explained.
  • the profile groove base 17 is further schematically shown in FIG. 2 the oblique profile groove 8 is drawn.
  • the bottom of the profile groove 17 is arcuate, in particular as a segment of a circle.
  • the Profilnutengrund 17 ends in the associated Key flat side 6 or in the longitudinal profile groove 14. This ensures that the edge region 39 of the Key back 18 runs smoothly.
  • 3 and 4 show two different profile variants 2 in the form of the key channel.
  • the Key profile is designed analogously.
  • Fig. 4 shows the six points of variation of the longitudinal profile grooves.
  • the four possible longitudinal profile grooves a, b, d and e can either be provided or not provided. There is always an overlap at the variation points c and f Longitudinal groove provided, but the position according to the height can be varied, resulting in a variation point results.
  • Fig. 3 shows the variant with the longitudinal profile grooves a, d and e, and the upper parts of the profile grooves c and f.
  • Fig. 4 shows a variation where the profile grooves on the key side d and e and the lower parts of the profile grooves c and f are used.
  • the profile grooves on the key naturally correspond to core ribs of the key channel.
  • FIG. 4 also shows the incision milling depths that are possible, for example 39 drawn, the optional for the control of tumbler pins can be provided (Fig. 1, reference numeral 11).
  • the oblique profile on everyone Key flat page 2 groups of 5 variation digits each has what can mean a maximum of 20 inclined profile grooves, the five variable longitudinal profiles result in a number of variations of approximately 35.5 million different profiles. This can still be done with the number of variations in the incision milling multiplied for each of the tumbler pins become. The result is an extremely high number of variations, where the individual variation points are independent of each other can be used.
  • the key cross section ensures in any case sufficiently high stability.
  • the analog The key channel profile of the lock is especially critical The area of the incisions is strongly curved and formed as an overlapped profile, whereby the locking is made considerably more difficult.
  • Fig. 4 are the depths of cut with the parallel Lines 39 are drawn.
  • the top line 39 limits the Notch area 4 (Fig. 1).
  • a tumbler pin 27 is in the key channel marked how it protrudes into the key channel, if no key is inserted.
  • the key channel shown in Fig. 3 is in the back area advantageously narrow because the core ribs a, d and e are provided. 4 are the core ribs a and b are absent, creating the profile is more open in the back area.
  • both ribs d and e provided to the Palpation of the lock difficult and the key when To guide insertion better.
  • FIGS. 3 and 4 illustrate the profile design when varying at this point.
  • the middle section 40 remains at the Core rib always preserved from full material, regardless depending on whether the rib starts from the central part 40 below (Fig. 4) or up (Fig. 3). The same applies analogously to the longitudinal grooves in the key.
  • Fig. 5 and the following show the cylinder core 24, which in the Cylinder housing 25 is rotatable.
  • the key channel 26 is an inventive key 1 inserted.
  • the in tumbler pin 27 arranged in a conventional manner under the pressure of the spring 28 the incision 29 on Key beard off.
  • the longitudinal profile grooves of the flat key 1 are more common Way from the appropriately trained core ribs of the key channel 26 scanned. If the key fits it can be pushed into the key channel, otherwise insertion is prevented.
  • the core ribs of the The key channel protrudes beyond the central longitudinal plane in the incision area 16, which gives the overlap effect.
  • the scanning of the oblique profile grooves 8 is done by locking strips 30 carried out, preferably a Block bar all provided on a flat key page Slanted profile grooves or ribs 8 scanned. Just if the scanning end 31 with the inclined profile grooves 8 of the associated Key flat side fits together, the locking bar 30 pushed inwards in the cylinder core 24 are so that the locking end 32 engages with the locking recess 33 releases, after which the cylinder core 24 rotates can be.
  • the section through the locking bar 30 on the right side 5 is placed somewhat differently than on the left side and shows a control pin 34.
  • the control pin 34 scans a part of the key where the key material must be fully preserved. This is the place 41 between the two groups of inclined profile grooves (Fig. 1). The way it works is described below. Through the control pin provided on each of the locking bars is prevented from being abusive Key imitators removed key material over a large area can be used to measure the effectiveness of the scan To bypass locking bars.
  • Fig. 6 shows a section analogous to Fig. 5, however has a rib 35 in the left half of the key and is therefore a wrong key. This rib 35 prevents the locking bar 30 from immersing in the cylinder core. The locking end 32 prevents the twisting Cylinder core.
  • the locking bar 30 is on both sides of the key channel displaceable in corresponding slots 42 in the cylinder core stored (see Fig. 5).
  • the scanning end is the scanning end 31 opposite. This scanning end 31 has the appropriate profiling for the oblique profile grooves 8 of the Key on.
  • the right angle profile group is shown five grooves or ribs and for the left Inclined profile group four ribs and grooves.
  • the control pin is slidably seated in the recess 43 34, the scanning head 36 and a guide pin 44th includes.
  • the guide pin is in the bore 45 of the locking bar 30 stored so that the control pin and its Readhead 36 is slidable. The way it works is 5 to 7 can be removed.
  • the web arranged on the underside of the locking bar 30 46 limits the penetration of the locking bar 30 in the Key channel 26 and it is for example on FIG. 5 referred.
