Definitions

  • the present invention relates to a security lock with a key according to the preamble of claim 1.
  • Known security locks of this type are designed such that their pins rest with a point practically point-like on the bottom of a notch or a conical recess of the inserted key, whereby the position of the pins or Tumblers in their holes is determined.
  • the accuracy of the key is comparatively low because the position of the notches or recesses does not have to be very precise if only their depth is correct. It is therefore relatively easy to copy keys with sufficient accuracy.
  • An object of the present invention is to significantly increase security in that the simulation of a key places far higher demands on precision.
  • This goal is achieved in that the key has transverse grooves on at least one pin track, on the two inclined flanks of which one pin rests without play in the unlocked state. If, in this case, the position or depth of only one groove on the key is not correct, the pin which engages in this groove or the associated tumbler will not reach the unlocked position and the lock cannot be operated.
  • Security can also be increased in that the axes of the grooves on the key are designed to be inclined to the longitudinal axis of the key and / or to the narrow sides of the key.
  • the lock shown has the usual parts, namely a sleeve-shaped outer cylinder or stator 1, an inner cylinder or rotor 2 and a sleeve 3 enclosing the stator 1.
  • the stator is provided with rows of radial bores 4 and 5, in which sleeve-shaped tumblers 6 and 7 are arranged so as to be radially movable.
  • the tumblers 6 and 7 are under the action of compression springs 8, which they try to move inwards.
  • the tumblers 6 and 7 press against pins 9 and 10, which are inserted radially movable in bores 11 and 12 of the rotor 2.
  • Fig. 1 further options for the arrangement of tumblers and pins are indicated by dashed lines.
  • FIG 1 also shows the profile of the key 13, which has two plane-parallel bottle sides 14, on one narrow side, a cylindrically curved surface 15 whose radius corresponds to that of the rotor 2 and on the other narrow side has an inclined surface 16, which according to FIG Surface 17 of the narrow side standing at right angles to the flat sides 14 encloses an angle a.
  • the key channel in the rotor 2 has a corresponding profile, such that only a key with the correct profile can be inserted into the lock.
  • a conventional pin race with conical depressions 18 is provided on the right-hand flat side of the key 13 in FIG. 1. Conical tips of the associated pins 10 engage in these depressions 18 and lie on the flat bottom thereof, whereby the position of the pins 10 and the associated tumbler 7 is determined.
  • a further explanation is unnecessary since the arrangement and mode of operation are the same. It should only be pointed out that, according to FIG. 2, the bores are axially offset from one another.
  • the type of these grooves 19, which have different depths, can be seen from FIGS. 3-6.
  • These grooves are inclined both with respect to the longitudinal axis of the key and form an angle y with a normal to the key plane or to a flat side of the key which is neither 0 nor 90 ° (FIG. 5).
  • the grooves are also inclined with respect to the plane of the key, in relation to a normal to Key plane or a flat side of the key through an angle a.
  • the bores 4 and 11 of the tumblers 6 and 9 also have a corresponding inclination by the same or approximately the same angle ⁇ with respect to the key plane.
  • the tumblers 9 thus move practically at right angles to the longitudinal axis of the associated grooves 19.
  • FIG. 6 it is shown that the tumblers 9 rest with a conical tip 9a without play on the two flanks of the associated groove 19, and that the pins 9 and the assigned tumblers 6 assume their unlocked position. It is therefore also clear that if the position of the groove 19 along the key or the inclination of the groove in any direction or its depth is incorrect in the case of an imitated key, the associated tumbler and the associated pin will not reach the unlocking position, so that the lock cannot be operated.
  • FIGS. 1, 5 and 6 the surface 17 forms a further pin raceway with conical bores 20 of a conventional type. It cooperates with pins and tumblers indicated in FIG. 1 but not described in greater detail, which are above the key are arranged in the plane in holes 5 "or 12".
  • FIG. 1 shows an embodiment in which the key has only one row of conical recesses 18 or 18 'on each flat side and one row of grooves 19 or conical recesses 20 on one narrow side and can thus only be inserted into the lock in one position
  • FIGS. 3-6 show an embodiment variant with a reversible key, each of which has two centrally symmetrical, identical pin slideways.
  • the bores 4 are assigned the scale S4 and the bores 5 "the scale S5".
  • the nineteen positions indicated are possible, although a distance of at least three divisions must be maintained between adjacent bores.
  • the corresponding positions for the conical depressions are only designated by crosses It is clear that the positions must correspond to those of the bore axes according to Fig. 2.
  • Fig. 5 it is indicated above that the conical depressions 20 must correspond to the positions according to scale S5 ". Which positions can be occupied depends on which positions are occupied by grooves 19 and what depth these grooves have.
  • the scale S4 indicates how the positions of the grooves 19 are to be measured.
  • the measuring point is a very specific point on the bottom of the groove, for example at the intersection of the axis of the bores 4 and 11 with the bottom of a groove or the cutting line between the two groove flanks.
