  • the predetermined path positions on the profile cylinder key can be arranged approximately centrally between the positions of the blind hole-like recesses.
  • the positions of the recesses for the tumblers and the predetermined track positions would alternate over the length of the key shank for aligning the optionally provided secantial slides.
  • the predetermined track positions on the profile cylinder key can also lie in a separate longitudinal area of the key shaft, where no blind hole-like recesses can be found.
  • the key shank would then be formed of two sections, a first section of which will be the track positions of the longitudinal groove has for aligning the secantial slide and the other longitudinal portion of the blind hole-like recesses for aligning the tumblers.
  • claims 6 to 10 relate to a combination of the profile cylinder key according to the invention with an associated profile cylinder, which is at least preparatory to receive the invention to be aligned Sekantialschieber.
  • the aligned position is achieved in the key insertion position.
  • the bore portions are arranged in the circular cylindrical housing part of the housing of the profile cylinder both above and below the lock core, so that the secantial slide automatically get into the locked position alone under the influence of their weight with not inserted access author profile cylinder key.
  • the profile cylinder can be rotated.
  • sekantial extending slot channels provided which cut the keyway and which serve the purpose to bring the sliding pins of any existing secantial slide in contact with the inventive curvilinear longitudinal groove on the profile cylinder key.
  • the width of the longitudinal groove according to the invention corresponds at least at the locations of the predetermined track positions exactly the width of the sliding pins less a sliding clearance in order to align the secantial slide as accurately as possible in terms of height.
  • the figures show a profile cylinder key 1 according to the invention.
  • a profile cylinder key 1 has a key crop 2 and a key shank 3.
  • the key shank has an approximately 8-shaped cross-section with widened waist area.
  • the key consists of two spaced over the waist 3c thick areas 3a, 3b.
  • Fig. 1c to 1e is an associated profile cylinder 9 equipped with radially aligned to the upper thick portion 3a of the profile cylinder key 1 tumblers 5, which cooperate with corresponding recesses 4 on the key shank 3 of the profile cylinder key 1.
  • the recesses 4 are variable according to arrangement and depth and can form a certain hierarchy in the access authorization of a locking system of several such profile cylinder keys.
  • the tumblers 5 each consist of core pins 6 and housing pins 7.
  • the tumblers 5 include compression springs 8, which are supported toward core pins 6 and housing pins 7 on the housing 10 of the profile cylinder 9 and act on the tumblers towards the keyway 19.
  • the tumblers 5 are cushioned for this reason in the direction of the profile cylinder key and, authorized access key, moved so in their position that they lie exactly with their parting planes between the core pin 6 and housing pin 7 in the rotational surface 14 between lock core 13 and housing 10 of the profile cylinder , so that then the lock core 13 can be rotated freely.
  • This is independent of the fact whether such a profile cylinder key 1 has the longitudinal groove 50 according to the invention or not, prior art.
  • the inventive profile cylinder key 1 to the recesses 4 for aligning the sprung tumblers 5 with respect to its key longitudinal axis 23 eccentrically arranged and between the outer boundary lines 29, 30 of the thick areas 3a, 3b curvilinear longitudinal groove 50 which extends from the key tip 27 and in the key insertion position 39 predetermined track positions 31, 32 offers. It is particularly important that a suitably equipped profile cylinder 9 alone provides the possibility to be able to align the secantial slides 15, 16 via the predetermined track positions 31, 32. This fact is in the Figures 1c to 1e be Tillt.
  • the secantial slide 15, 16 are present and the longitudinal groove 50 on the profile cylinder key 1 according to the invention is used in the case of an authorized key to align the one hand, the sprung tumblers 5 and on the other hand, the alignment of the secantial slide 15, 16th
  • Fig. 1c shows, protrude both the cushioned tumblers 5 and the secantial slide 15, 16 with their attached sliding pins 17, 18 in the keyway 19 into it.
  • the tumblers 5 have been aligned so that core pins 6 and housing pins 7 lie with all their parting planes exactly in the rotating surface 14 and the secantial slide 15, 16 also no longer block a free rotation of the lock core 13 relative to the housing 10. In this situation, the lock cylinder can be actuated and perform its opening function.
  • Fig. 1a shows in particular Fig. 1a in that the curve of the longitudinal groove 50 is between two predetermined Curve boundary lines 20, 21 runs and for each key broadside on only one of the two thick areas 3a, 3b of the profile cylinder key first
  • the longitudinal groove 50 in the region of the key tip 27 an inlet funnel 22 whose opening width at least the distance of the curve boundary lines 20, 21 corresponds, so that the sliding pins 38 of the Sekantialschieber 15, 16 can dive virtually smoothly into the longitudinal groove 50 when the profile cylinder key 1 in the keyway 19 is inserted.
  • Fig. 1a shows a predetermined track positions 31, 32 are arranged between the positions of the blind hole-like recess 4.
  • Fig. 2 shows that the predetermined track positions 31, 32 lie in a separate longitudinal region 28 of the key shaft 3, where no blind hole-like recesses 4 can be found.
  • the longitudinal groove 50 thus extends only over the longitudinal region 28, that is to say a part of the key shaft 3.
  • a development of the profile cylinder key according to the invention is characterized in that it is point-symmetrical with respect to its longitudinal center axis, which in this case is the center line 24 of the key shaft 3, including the longitudinal groove 50, which then also with respect to Center line 24 of the key shaft 3 is arranged point-symmetrically.
  • Fig. 2 shows in addition Fig. 2 the interaction of a combination of a profile cylinder key 1 and a profile cylinder 9, the lock core 13 a to the cross section of Profile cylinder key 1 corresponding key channel 19, in which are provided at the predetermined by the blind hole-like recesses locking cylinder side spring-loaded tumblers 5.
  • the key shank is shown here in longitudinal section.
  • the longitudinal groove 50 according to the invention is not shown over the entire length, but merely indicated.
  • the longitudinal groove 50 provides predetermined track positions 31, 32 at which the profile cylinder has the secantially extending holes 34 in which the secantial slide 15, 16 are arranged.
  • the secantial slide 15, 16 have corresponding sliding pins 17, 18, which protrude into the keyway 19.
  • the sekantial extending holes have slot channels 35 which also extend secantially and which ultimately mesh with the keyway 19.
  • such a profile cylinder 9 has a housing 10, which consists of a circular cylindrical housing part 11 and an attached thereto web-like housing part 12.
  • Fig. 2 a situation in which the tumblers 5 and the secantial slides 15, 16 lie in different longitudinal areas.
  • the secantial slide the separate longitudinal portion 28 which can be found in the front part of the key shaft 3.
  • the secantial pushers 15, 16 can, but need not sit in corresponding holes 34.
  • the secantial bore in the lock core 13 continues a short distance into the housing 10, so that secantial slides 15 located in the secantial bores can enter into the housing 10 both upwardly and downwardly from the lock core, in particular the Fig. 1c to 1e also show.
  • the key insertion position 39 is characterized in particular by vertical arrangement of the keyway 19, so that the secantial slide 15, 16 are subjected to force in the key insertion position 39 exclusively by their own weight.
  • the entire system can also be arranged horizontally.
  • the profile cylinder according to the invention provided that secantial slides are provided, therefore offers increased break-in protection.
  • the longitudinal groove 50 has a constant width from the end of the inlet funnel.
  • the width of the longitudinal groove 50 may according to the invention, however, also vary, it can be constant over the entire length, it can be constant over longer sections and above all it can be punctually at the predetermined track positions 31, 32, where the secantial slide 15, 16 too are found exactly the width of the sliding pins 17, 18 correspond.
  • positions 25, 26 of the recesses 4 are basically also completely independent of the track positions 31, 32 for the optionally present secantial slides 15, 16.
