Definitions

  • the invention relates to a locking device with a locking cylinder and a Reversible key designed inner track flat key.
  • Such a locking device is known for example from DE 299 23 496 U1.
  • This known device is a 4-lane internal locking system.
  • the lock cylinder comprises a cylinder housing and one rotatable in the housing stored cylinder core, being in the key channel of the cylinder core transverse to this Spring-loaded frame-shaped displaceable from a locking position into an unlocking position Tumblers (plates) are arranged.
  • the frame-like tumblers are from its locked position to its unlocked position by inserting the key bit of the flat key moved into the key channel, one in the interior of the respective cam-shaped guard locking cam on a corresponding Inner track (step milling track) of the key bit is supported.
  • a disadvantage of this known locking device has been that when in use of locking cylinders, in which the control cam of the frame-shaped tumblers in the locked position of the tumbler relatively far from the inner surface of the key channel are displaced when inserting the associated flat key into the key channel the control slope of the inner track on the front of the key is none safe movement of this control cam causes more, and the key can not be push further into the key channel of the cylinder core.
  • the invention has for its object to provide a locking device in which with the intended flat key the tumblers even from their Can be actuated in their unlocked position when the control cam of the corresponding in their locked position tumblers in the immediate vicinity of the Wall area of the key channel is arranged.
  • the invention is essentially based on the idea of the tumbler, the control cam in the locked position up to the immediate vicinity of the wall area of the key channel extends, such that the control cam - in the direction of its Unlocking movement - opposite inner wall also in the key channel protrudes.
  • the key bit of the flat key protrudes slightly on the tip side the control slope of the inner track, on which the control cam is supported, and has a key edge opposite this inner track, one on the front Tapered bevel towards the tip of the key or a correspondingly rounded area has, such that when the key bit is inserted into the key channel Key edge first presses the tumbler sideways out of the key channel so that the Control cam is pressed into the key channel at the same time and the control slope the inner track can reach behind the control cam.
  • the locking device is concerned a 4-lane internal locking system, in which the key bit of the flat key has an incision track on each of its broad sides, each of which has two lateral, inner tracks extending in the direction of the longitudinal axis of the flat key is.
  • the two opposite ones arranged in front of the control slopes of the inner tracks Key edges in turn each point towards the key tip Ramp or a correspondingly rounded area.
  • the two inner tracks of the 4-track inner locking system an incision path of the key bit one parallel to each other directed course, with the distance between the two inner tracks approximately the Width of the control cams corresponds to the frame-shaped tumblers of the cylinder core, so that when the key bit is inserted into the key channel of the cylinder core Control cams for forced guidance on both sides through the opposite inner tracks experienced an incision trajectory.
  • Fig. 1, 1 is a locking device with a locking cylinder 2 and a reversible key trained inner track flat key 3.
  • the locking cylinder 2 comprises a cylinder housing 4 and a cylinder core rotatably mounted in the housing 4 50th
  • the frame-shaped tumblers 5-12 are inserted by inserting the key bit 15 of the flat key 3 in the key channel 60 perpendicular to the longitudinal axis 16 of the cylinder core 50 moved.
  • 5-12 is on each of the frame-shaped tumblers
  • Control cams 17-24 extending into the interior of the tumbler 5-12 are provided.
  • the key bit 15 of the flat key 3 has one on each of its broad sides Cutting path 25, each by two lateral, in the direction of the longitudinal axis of the Flat key 3 extending inner tracks (step milling track) 26, 27 is limited, on which the control cams 17-24 of the tumblers 5-12 are supported.
  • the two inner tracks 26, 27 of an incision track 25 of the key bit 15 have a course directed parallel to one another, the distance between the two inner tracks about the width of the control cam 17-24 of the frame-shaped tumblers 5-12 of the Cylinder core 50 corresponds, so that when inserting the key bit 15 into the key channel 60 of the cylinder core 50, the control cam 17-24 a double-sided positive guidance through the opposite inner sheets 26, 27 of one of the two incision sheets 25 Experienced.
  • the tumbler designated by 12 is in its locked position so far moved to the inner surface 28 of the key channel 60 that at Insert the flat key 3 into the key channel 60 in the tip-side area of the key bit 15 located control slope 30 of the inner track 27 no reaching behind of the control cam 24 and thus also no shifting of the associated tumbler 12 does more.
  • the inner wall 31 opposite the control cam 24 also projects the corresponding tumbler 12 in the locked position of the tumbler 12 also in the Key channel 60 into it.
  • the key bit 15 of the flat key 3rd protrudes on the tip side approximately over the control bevels 29, 30 of the inner tracks 26, 27 and has a key edge 32, 33 opposite the respective inner track 26, 27, the front is a bevel 34, 35 or has a correspondingly rounded area, such that when inserting the key bit 15 in the key channel 60 this in the case of the embodiment shown in FIGS. 1-3 first, with the key edge 32, the inner wall 31 of the tumbler 12 from the key channel 60 laterally (downwards), so that this tumbler 12 assigned control cams 24 is pressed further into the key channel 60 and the control bevel 30 of the inner track 27 can engage behind the control cam 24.
  • the tip-side lower area of the theft tool 36 would against the in the key channel 60 protruding inner wall 31 of the tumbler 12 and could also for this reason, are only partially inserted into the key channel 60.
  • the tumbler would 12 in the lower due to the height of the cam 37 Locking groove 13 of the cylinder housing 4 is pushed and pressed there against the locking groove wall 39 be, which also leads to a blocking of the insertion movement of the theft tool 36 would lead.
