Definitions

  • the invention relates to a lock-key system with a cylinder core rotatably mounted in the cylinder housing and a lock bit which can be coupled with a flat key that can be inserted into the keyway of the cylinder core to perform a common turning process that triggers the locking function.
  • a FZG clutch is characterized by the fact that the cam can disengage under load as soon as the key is removed.
  • the coupler contours feature double sloped contact surfaces that result in the coupler adapter being pushed back into the cylinder core once the key is removed. Furthermore, this contour is designed in such a way that the mechanism does not jam when the key is pulled under load and the locking bit can be disengaged.
  • the new solution is an indirect or indirect key tip coupling, since here an adapter piece instead of the key tip - as with the DE 102019125164.8 was suggested - was used.
  • an adapter piece instead of the key tip - as with the DE 102019125164.8 was suggested - was used.
  • the coupling adapter With cylinder lengths greater than 30 mm, the coupling adapter can be extended using simple cylindrical pressure pieces.
  • the lock bit is also constructed somewhat differently, so that the lock bit is always turned away from the coupling adapter when the key is inserted, allowing the key to be fully inserted.
  • the solution described shows, among other things, a reversible key system that touches the center of the coupling adapter or moves it.
  • the coupling adapter and the cam have a symmetrical design to enable better distribution of forces.
  • At least two "noses” are provided in the lock bit for entrainment.
  • These carriers have a triangular profile with corresponding slopes for the coupling and for driving.
  • the inclined driving surfaces on the adapter and cam correspond to each other (have the same angle), which is between 30° and 45°.
  • the coupling piece is designed in the shape of a cutting edge with slight bevels so that the first point of contact is further away from the middle axis (only in the example of a reversible key; with the flat key, the point of contact is on the outer radial area) .
  • the cam also has a blade-shaped area that is also bevelled.
  • the adapter When the key is removed, the adapter can be disengaged by turning the cam or by coupling and turning the other side of the cylinder. It is simply pushed back into the cylinder core via the coupling bevels. This ensures the so-called “FZG” function.
  • this solution offers a "BS” function that allows locking from both sides (the key is on the inside, but it can still be unlocked from the outside; the inside also rotates).
  • Another advantage can be the "freewheel function" when no key is inserted (the lock bit can be rotated freely; 360°).
  • a double lock cylinder 2 with a reversible key 1 is shown in a side view.
  • the cam is denoted by 5.
  • the sectional view AA of figure 2 shows the cylinder core, which is rotatably mounted in the lock cylinder housing 2 as usual.
  • the lock bit 5 facing on both sides are provided in the key channel coupling adapter 4, 4a, which are rotatably mounted but axially displaceable in this.
  • the cylinder core 3, the cam 5 and the coupling adapter 4 are in the Figures 2 to 5 Details of the coupling surfaces on the cam 5 can be seen, namely the 30° coupling surfaces 6 on the cam 5 with the blade-shaped, slightly slanted area 7 and on the coupling adapter the blade-shaped, slanted coupling surfaces 8 and bevels 9.
  • a rotary movement of the key 1 can thus be transmitted via the cylinder core to the lock bit, so that a locking process can be carried out.
  • the cam is denoted by 15.
  • the coupling surface 14, which is provided with bevels, is located asymmetrically on the surface 13.
  • the coupling adapter 10 is rotatably but axially displaceably mounted in an upper recess of the key channel in the cylinder core 3 and has coupling surfaces 11 with bevels, as is shown in detail in FIG figure 9 is shown.
  • the figure 10 shows the uncoupled state, ie the key 1 has not yet been inserted into the keyway in the cylinder core 3.
  • the coupling adapter 10 moves axially in the direction of the cam 15 ( 13 ) up to the stop or engagement of the coupling surfaces 11 and 14, so that the coupling key 1, cylinder core 3 and lock bit 15 is also established in this embodiment.
  • the coupling adapter In the event that the edges of the coupling contours of the coupling adapter and the lock bit are directly above one another when the key is inserted, the coupling adapter is pressed into its coupling position by its sloping surfaces and the sloping driving surfaces in the lock bit. Due to a positive fit of the sloping surfaces in the lock bit and on the coupling adapter, the lock bit is thus carried along during a closing process.
