Definitions

  • the invention relates to the design of the cross-sectional profile of a key channel and the matching key or key channel.
  • the EP 0 567 832 A1 describes a cross-sectional profile, a lock cylinder and the matching key.
  • the profile longitudinal center plane extends at an acute angle inclined to the longitudinal center plane passing through the tumbler pins of a profile lock cylinder such that the profile section located on one side of the key shank lies in the aforementioned longitudinal center plane. In this way, one obtains an ergonomically favorable arranged keyway and extensive concealment of the cross-sectional profile.
  • the key has a median longitudinal plane, with portions of the key channel can run both straight and arcuate. In particular, in arcuate portions of the key channel V-shaped corners form, within the channel. The total cavity of the profile is divided there in an upper and a lower portion such that the two portions are offset from each other to the key channel center plane. This should make the use of scanning tools difficult.
  • the EP 078053 A1 describes a cylinder lock with a matching key, in which the keyway also has an upper and a lower portion.
  • the upper portion of the keyway has a profile center plane which is inclined to the profile center plane of the lower portion. Laterally profile sections extend to the profile variation.
  • the US 4,653,298 describes a lock cylinder with a matching key, wherein the keyway or the profile of the matching key forms a plurality of mutually perpendicular profile sections. Two of these perpendicular to the profile longitudinal median plane extending profile sections have acute angle to each other running wall sections.
  • the object of the invention is to provide a generic cross-sectional profile in which the opening of the lock cylinder is largely prevented even when using working with high power and frequencies picking the task.
  • a lock cylinder is given, which is a increased safety value. Opening the lock cylinder according to the Hobbian opening method by means of high impact and high frequencies working picking devices is largely prevented.
  • the picking needle In order for the picking needle to reach its maximum impact amplitude after insertion into the keyway, it must be aligned so that it passes through the opposing profile sections. Due to the design of these profile sections, however, the picking needle experiences a blockage, so that the impact force can no longer be sufficiently effective on the core pin tips. Therefore, the tumbler pins can not be properly arranged to rotate the cylinder core can.
  • both opposite profile sections can be effective in terms of blockage, the Schmalend vom the profile sections are connected by a movement channel for the picking needle.
  • the profile sections form acute angles to each other to running, leading to the Schmalend vom wall sections. These run inclined to the plane of vibration of the picking needle and cause by the impinging on them picking the braking or blocking effect. Optimal proves it that the mouth between the wall sections is greater than the width of the picking needle and the width of the narrow end surfaces is smaller than the width of the picking needle. It should then be emphasized that the profile sections project beyond the broad side surfaces running parallel to the profile longitudinal center plane. The cross-sectional profile can then form a paracentric base profile, so that even with the use of manual picking the opening according to the Hobbian opening method is difficult. It is envisaged that the angle enclosed by the profile longitudinal center plane and the movement channel center plane is less than or equal to 45 °.
  • This angle is to be determined as a function of the basic paracentric profile provided that the picking needle is inserted into the keyway at an angle of approximately 30 ° in order to achieve the maximum amplitude of oscillation.
  • the projection of the profile sections is chosen so large that it corresponds to about half the profile thickness.
  • the corresponding flat key is designed with a cross-sectional profile according to one or more of the preceding claims. This also applies to a lock cylinder with a key insertion profile, which is designed according to one or more of the preceding claims.
  • lock cylinder 1 is a double-profile lock cylinder.
  • This has a housing G with a circular in plan view section 2, from which a radially projecting flange 3 starts. Then, the housing G is provided with an outgoing from the circular section 2 cutout 4 for receiving a closing member 5 with radially projecting cam 6th
  • a cylinder core 8 is mounted in each circular section 2 in a core hole 7.
  • the keyway 9 has a key channel 9 whose profile longitudinal center plane x-x is in alignment with the plane of movement of the pin tumblers located behind the other, arranged in the housing.
  • Each Stiftzuiens is composed of a core pin 10 and a sprung in the direction of the same housing pin 11, wherein the core pins 10 facing ends of the housing pins 11 protrude with removed key in the core pins 10 receiving core holes and thus block the rotational movement of the cylinder core 8.
  • the profile longitudinal center plane xx of the key channel 9 is limited by the narrow sides of the cross-sectional profile.
  • opposite profile sections 12, 13 are provided to the narrow sides of the key channel towards V-shaped expiring.
  • the profile sections 12, 13 form an angle alpha of approximately 45 ° relative to the profile longitudinal center plane xx. This angle is shown in FIG. 2 at the profile section 12. A corresponding angle is also in the profile section 13, which is not shown.
  • the profile sections 12, 13 are the first, opposite profile sections, parallel to which second, also V-shaped projecting profile sections 14, 15 extend. The latter are adjacent to the profile transverse center plane, ie have a smaller distance to it than the first profile sections 12, 13.
  • the second profile sections 14, 15 also extend at an angle of approximately 45 ° to the profile longitudinal center plane xx.
  • the Schmalend vom 12 ', 13' of the profile sections 12, 13 are interconnected by a movement channel B for a picking 16.
  • the latter is part of an electric picking device, which works with high power and high frequency. The frequency is also adjustable if necessary. From Fig. 2 it can be seen that the movement channel B is approximately rectilinear. The movement channel has an angle of about 30 ° to the profile longitudinal center plane x-x. Under this, the picking needle 16 is inserted into the keyway 9, wherein the maximum oscillation amplitude of the picking needle is achieved.
  • the profile sections 12, 13 have wall sections 12 ", 12" 'and 13 ", 13" leading to one another at an acute angle, leading to the narrow end surfaces 12', 13 ''.
  • FIG. 2 illustrates that the cross-sectional profile is a paracentric basic profile. This means that of the broadside surfaces 17, 18 outgoing profile ribs extend at least to the profile longitudinal center plane xx.
  • the second profile sections 14, 15, which correspond in terms of their dimensions to the first profile sections 12, 13, project beyond the broad side surfaces 17, 18 of the base section.
  • the projection of the profile sections 12, 13, 14, 15 corresponds approximately to half the profile thickness.
  • Fig. 2 there is an interrupted movement channel between opposing first and second profile sections.
  • the profiled corner 20 protrudes into the movement channel for the picking needle, so that when the picking needle vibrates in the last two movement channels, a torsional moment becomes active on the picking needle, which quickly increases a fraction of the same leads.
  • the cross-sectional profile of the keyway 9 of a lock cylinder 1 has been described. According to this cross-sectional profile of the cross-section of the associated flat key is designed, in which the profile sections are designed as a corresponding aligned ribs.
  • the cross-sectional profile of the key channel 21 shown in Fig. 4 corresponds to the basic profile of the keyway 9 of the above-described embodiment. This means that the keyway 21 no profile sections assigned. Due to this fact, a picking needle 16 can be inserted into the keyway 21 such that the oscillation amplitude y is at an angle of about 30 ° to the profile longitudinal center plane xx. Since there are no profile sections on the keyway 21, the picking needle 16 can be fully effective at the beveled tips of the core pins and arrange them.
