Definitions

  • the invention relates to a lock cylinder with a arranged rotatably in a cylinder housing, one Key channel having cylinder core, in which interacting with the key side profiling Locking elements can be moved transversely to the key channel axis are guided, which one-sided with their locking end with a locking recess in the cylinder housing interact and which on the other side Form key-side profiling scanning probe and at least two in the key insertion direction successive locking elements over a web to a locking bar motion connected are.
  • a lock cylinder of the type in question is known from US 4,723,427, the locking bar in Locking projections pointing in the direction of the key channel going out.
  • the latter are designed like a bridge and run parallel to the longitudinal axis of the tumbler pins.
  • the Core pins have longitudinal grooves and are through the Key notches rotated overlapping and shifted in such a way that the longitudinal grooves are aligned with the locking projections.
  • the Longitudinal grooves with transverse grooves on the key shank see above that when the closing rotation begins, the locking projections both in the longitudinal grooves of the core pins and in the Intervene in the keyways transverse grooves.
  • This configuration allows a key with which the Closing notches are correct and which is not the transverse grooves on the key shaft, by filing it like this to revise that it closes anyway.
  • the object of the invention is based on the object a generic lock cylinder with simple Specification of increased locking security.
  • This task is first and foremost a locking cylinder with the features of claim 1 solved, with the focus that two diametrically opposite locking bars with each offset interlocking projections are provided, with at least one tip of the opposite Locking projections in their core rotation Position penetrate a common level.
  • the Locking bars have insertion openings for the locking projections training insert pins. This leads to a simple and cost-saving production.
  • the locking projections are only the insertion pins insert into the insertion openings of the locking bar.
  • Insertion openings optionally with insertion pins equip. So that the insertion pins in their insertion openings are locked, the plug pins in the insertion openings in the press fit.
  • Insert pins assigned to assign the insertion openings with a different projection of the probes the insertion pins over the locking bar. Further it is still advantageous in terms of manufacturing technology that the frustoconical ends of the insertion pins with similarly shaped sampling funnel openings of the key work together.
  • the locking cylinder shown in Figures 1 to 4 has a plan circular cylinder housing 1.
  • a different cross-sectional shape of the cylinder housing possible, e.g. an oval or a profile cylinder.
  • a central core bore 2 takes the cylinder housing 1 a cylinder core 3.
  • the latter has one cross-sectional key channel 4 with a paracentric key channel profile. Is one-sided the key channel 4 to the core hole 2 open.
  • each other aligned pin holes 5, 6 In the plane of the key channel 4 are one behind the other in the cylinder housing 1 and cylinder core 3 with each other aligned pin holes 5, 6 provided, wherein each with a pin bore 5 of the cylinder housing 1 a pin bore 6 of the cylinder core 3 is aligned.
  • the Pin hole 6 takes a core pin 7 and the pin hole 5 a housing pin 8.
  • the latter is from a pin spring 9 is applied in the direction of the core pin 7 such that when the key is removed, the parting line between core pin 7 and housing pin inside of the cylinder core 3, so that the tumblers performing core pins 7 and housing pins 8 a Lock the rotation of the cylinder core 3.
  • the pin hole 5 of the cylinder housing 1 is on the outside by a Plug 10 covered, on which the one End of the pin spring 9 supports.
  • the guide recesses 11, 12 are spaced from one Diametral plane and are located on the Tumblers opposite half of the cylinder core 3. Furthermore, the guide recesses 11, 12 to to the circumferential line of the cylinder core, i.e. up to the rotary joint F of the same inside the cylinder housing 1. With the guide recesses 11, 12 are aligned in the form of longitudinal grooves designed locking recesses 13, 14 of the cylinder housing 1. Each locking recess 13, 14 has two inclined flanks 15, 16 running towards each other in a roof shape The protrude into the recesses 13, 14 to fit the shape Locking ends 17 of the locking elements S. The outer End face 17 'of the locking ends 17 is curved such that the curvature course that of the rotary joint F is adjusted.
  • each locking element S forms a probe facing the key channel 4 19 from with transverse to the key channel axis Vertex lines 19 ', which run in an arc shape.
  • the apex line 19 ' is from the top of two Roof flanks 20 shaped, which are also arcuate Show course.
  • the locking projections are particularly illustrative or the probes 19 of the opposite locking bars 18 offset from each other. That means, that the apex 19 'of a locking bar 18 on Gap sit to the apices 19 'of the other locking bar 18th
  • the cross-sectional profile of the key shaft 4 is adapted a key 21.
  • Its key tip 22 is with two roof-shaped, in which Key slopes expiring tax slopes 23 fitted.
  • the key 21 has on it the narrow edge incisions 24 for arranging the core pins 7 and housing pins 8 tumblers formed. It lies in the rest paracentric key profile. It means that at least one originating from the key broadsides Groove extends to the key longitudinal median plane or this cuts.
  • the bow notches 25 are incorporated by means of a side milling cutter, which is so large in diameter is that the linear apex 19 the bottom of the notch 25 'is adapted.
  • the tumbler pins are arranged so that their separation point at the level of the rotary joint F of the cylinder core 3 lies. Furthermore, the notches 25 lie on the Key broadsides the relevant vertices 19 'of Probes 19 of the locking elements S opposite. It can now the closing rotation is carried out by means of the key 21 be, with the sloping sides 15, 16 of Locking recesses 13, 14 including the locking elements S. of the webs 18 connecting them in the direction of Key broadsides are being relocated to that the probes 19 fill the form in the notches 25 occur. The apex 19 'of the probes 19 are then at notch bottom 25 '. The closing rotation can thus continue to be carried out.
  • the ends 26 'of the key channel 4 facing the Insert pins 26 are frustoconical and act with similarly shaped sampling funnel openings 29 together on the key broad side surfaces.
  • the locking bars 28 correspond to this second embodiment in its construction the locking bar 18 of the first Embodiment.
  • the cylinder housing protrudes radially outwards Beam section 28 'of the locking beam 28 into it.
  • Whose outer end 28 '' is curved such that the curvature curve adapted to that of the rotary joint F. is.
  • With the beam section 28 ' they act roof-shaped mutually extending inclined flanks 15, 16 of the locking recesses 13, 14 together.
