Definitions

  • the invention relates to a flat key for a cylinder lock, the key having at least two permanent magnet pills in the key shaft and at least one longitudinal profile groove being provided along the key face and / or along the key back. Furthermore, the invention relates to an associated cylinder lock, in particular with permanent magnet rotors, with a key channel, on the side surfaces of which holes are provided in the cylinder core, in which displaceable locking elements are arranged, the longitudinal extent of which corresponds to the distance from the key channel to the cylinder surface of the cylinder core.
  • the invention is based on a prior art, as disclosed by AT-PS 371 881.
  • the known key has several permanent magnet pills in the key shaft, which control corresponding magnetic rotors in the associated lock. Additional variation elements of this key are given by the profiling of longitudinal guide grooves along the key face and the back of the key, and by the arrangement of chamfer cuts on the longitudinal edges of the key, which interact with spherical locking elements of the lock.
  • the aim of the invention is to improve the variety with good mechanical stability, in particular the area between the permanent magnet pills should be usable.
  • the flat key according to the present invention is characterized in that at least one of the longitudinal profile grooves is extended and deepened as a control longitudinal groove in the area between at least two of the permanent magnet pills.
  • the associated cylinder lock is characterized in that at least one shorter and one longer locking element are arranged in row at least on one side surface, which protrude into the key channel to different extents according to the length difference and to scan recesses of the key with different depths.
  • the cylinder lock is characterized in that at least one shorter and one longer locking element are arranged in row at least on one side surface, which protrude into the key channel to different extents depending on the length difference and to scan recesses of different depths (longitudinal control groove and extension) of the key.
  • Fig. 1 shows a side view of the key according to the invention.
  • Fig. 2 shows a cross section through the key along the line II-II in Fig. 1, two locking elements of the associated lock are shown.
  • Fig. 3 shows a torn schematic cross section through the castle.
  • Figures 4 and 5 show two examples of the variation scheme
  • the key 1 comprises a key shaft 2 and the key handle 3.
  • the key shaft 2 there are four permanent magnet pills 4 which carry magnetization in a known manner.
  • the permanent magnet pills are preferably arranged and fixed in through holes in the key shaft, and the magnetic coding can be provided on each key flat side.
  • a longitudinal profile groove each runs along the key back 5 and also along the key face 6, the one along the key back being designated as the control longitudinal groove 7 and that along the key face as the guide longitudinal groove 8.
  • control longitudinal groove 7 carries an extension 9 in the area between all four permanent magnet pills 4, which also means a depression of the longitudinal guide groove 7.
  • the longitudinal guide groove 8 is just pulled through. However, it can also be designed as a longitudinal control groove and this equally on both key flat sides 10.
  • Fig. 2 shows a section along the line II-II in Fig. 1, wherein the associated locking elements 11 and 12 of the lock are also shown.
  • the locking element 11 is designed (longer) so that it fits the extension 9.
  • the locking element engages obliquely from above into the longitudinal control groove 7 and its extension 9.
  • the longitudinal control groove corresponds, also with its extension, to a right-angled, uneven triangle, the hypotenuse of which is formed by the key flat side 10.
  • the longer triangle side is the groove flank 13, which extends obliquely from the key flat side 10 to the central longitudinal plane 14 up to the control base 15.
  • the position of the scanning surface 16 is shown in broken lines if, at this point, no extension 9, but the longitudinal control groove 7 would be provided without this extension.
  • the obliquely opposite other locking element 12 of the lock is a shortened locking element which interacts with the control base 15, which is part of the longitudinal control groove 7.
  • the longitudinal control groove lies opposite each other, on the key back 5 as well as on the key face 6, a longitudinal guide groove 8.
  • the groove base 17 is preferably arranged parallel to the groove flank 13. This design of the guide grooves ensures that the key maintains sufficient mechanical strength and yet the guide groove 8 is brought up to the central longitudinal plane 14.
  • the longitudinal guide grooves 8 can also have different cross-sectional shapes in order to bring about additional closing differences.
  • Fig. 3 shows schematically a cross section through a lock and associated key, the key having a modified design of the longitudinal control grooves.
  • the shorter locking element 11 sits in the cylinder core 18 in a blind bore 19 and projects with the scanning surface 16 through the side surface 25 of the key channel 20 into which the key 1 is inserted.
  • the tax reason 15 is through the control longitudinal groove 7 is formed.
  • the cylinder housing 21 has a latching recess 22, which allows the locking element 11 to be displaced in the zero position of the cylinder core:
  • the longer locking element 12 is arranged, to which the associated extension 9 is assigned on the longitudinal control groove 7.
  • the lock can be locked in a known manner by means of a spring-loaded tumbler pin (control pin) which is located in the cylinder housing in the same rotational plane as the locking element. This control pin would snap into the bore 19 after rotation of the cylinder core and block the lock.
  • a spring-loaded tumbler pin control pin
  • the two longitudinal control grooves 7 in FIG. 3 have a different cross-sectional shape.
  • the advantage here is that 18 ribs 23 are provided in the cylinder core, which protrude into the key channel 20 and the leadership of the locking elements 11, 12 improve.
  • the cross-sectional shape of the ribs 23 corresponds to the longitudinal control groove 7 without the extension 9.
  • Figures 4 and 5 show schematic key cross-sections with the respective possible training of the tax reason.
  • Fig. 4 corresponds to the embodiment according to Fig. 2.
  • the number of possible control reasons depends on the scanning accuracy and can e.g. also include three tax reasons, so that three different lengths of the locking element 11, 12 are possible in the castle.
  • this term also includes any key blank in this regard, which has all these longitudinal profile elements and is only made into the finished key later by attaching further millings.
  • Such key blanks are e.g. made for locksmiths who complete the key according to customer requirements.
  • the key can be provided with further variation elements, e.g. the chamfer cuts according to AT-PS 371 881 or conventional key recesses on the key face for known pin tumblers.
