Definitions

  • the invention relates to a locking system with contact surfaces, namely on the one hand a method for coding the key and locking stamp of a lock of a locking system, and also a correspondingly designed lock of a locking system.
  • a generic method is from the FR 2 877 974 A1 known.
  • Key and locking stamp are each produced with the aid of a base body, to which a separate component, namely the respective coding part, is assigned.
  • the coding parts of the key and the locking stamp fit together so that the locking stamp of the lock can be operated with the key.
  • contact surfaces The surfaces of both components, where a coding part rests on a base body, are referred to as contact surfaces, and these interacting contact surfaces on the coding part on the one hand and on the base body on the other hand are geometrically designed in such a way that they enable a plurality of different rotational positions in which the same coding part is optionally attached to the base body can be.
  • the coding parts can therefore be produced in a small series and, because they can be fastened to the base body in different rotational positions, always differently designed keys or locking stamps, because the locking system is designed such that the key is only in a predetermined orientation the locking ram can be brought up. If two keys have identical coding parts, which are, however, mounted on their respective base bodies in a different angular position, only one of these two keys can fit the associated locking stamp, while the second key does not represent a functional key for this locking stamp.
  • the coding parts are each designed as coding disks.
  • the present invention is based on the object of improving a generic method in such a way that the production of the key and the locking stamp is simplified and, in addition to this simplification, a further economic advantage can be achieved in that identically configured coding parts can be used in as large a number as possible and at the same time ensure that only a single functional pair of locks is created. Furthermore, the invention is based on the object of specifying a lock of a locking system in which the key and locking stamp can be arranged to form the largest possible number of differently coded lock pairings using as few different components as possible.
  • the invention proposes a method in which the interacting contact surfaces on which a coding part rests on a base body are not coded in the sense that they can only be connected to one another in a few predetermined rotational positions. Rather, the base body and the coding part can be rotated steplessly relative to one another, so that they can be arranged in almost any rotational positions relative to one another. If no stop is provided that limits this rotary movement, the two components can be freely rotated against each other through a full 360 °. If, however, a stop should be provided that limits this rotary movement, any number of different rotary positions are possible within the available rotary angle range.
  • a large number of differently coded keys or locking stamps can be created that have very narrow gradations of different rotational positions between the coding and base part without the need for a highly precise, fine mechanical design of the contact surfaces with correspondingly finely rasterized profiling.
  • the contact surfaces are designed with smooth surfaces.
  • one contact surface is profiled and the opposite contact surface is smooth, so that in this configuration too the coding part can be rotated as desired with respect to the base body and, in this respect, there is no rotation of the two contact surfaces, which would affect the possible rotational angle positions of the two Components would restrict each other. If necessary, both components can even be profiled if this does not lead to a restriction of their rotational mobility relative to one another.
  • a radial, radial corrugation can be provided on one contact surface and a circular, concentric corrugation on the other contact surface, so that these two profiles running in different directions do not lead to a toothing of the coding part on the base body and accordingly the rotational mobility between these two components is not restricted.
  • These profiles enlarge the surface of the respective contact surface and can therefore be advantageous for other reasons, as will be explained further below.
  • the coding part is axially screwed to the base body along their common center line. Due to the profiling of the contact surfaces, deviating angles of rotation are ruled out there once the coding part is fixed on the base body, for example by means of the screw connection mentioned.
  • a mechanical definition of the respective angle of rotation position that the coding part assumes with respect to the base body is not provided.
  • the coding part must nevertheless be attached to the base body in the selected angle of rotation position in such a way that the two components are connected to one another in a tensile and rotationally fixed manner, that is, secured against forces which tend to rotate the two components against each other or to pull them apart.
  • two parallel threaded bores can be produced in the axial direction in order to screw the coding part to the base body in a torque-proof and tensile manner.
  • the two components overlap in the axial direction so that they can be pinned or screwed to one another by means of a radial bore that runs through both components.
  • the coding part on the base body without such a complex mechanical Post-processing is attached.
  • provision can be made for these two components to be glued or welded to one another, or to be connected by means of a potting compound.
  • adhesive can be provided between the two contact surfaces. The profiling explained above can enlarge the surface of the contact surfaces and thus improve the force transmission from a component to the adhesive.
  • the potting compound can be cured and then - possibly even without an adhesive effect - bring about a form fit between the coding part and the base body, even if these two components do not lie directly against one another in a form-fitting manner, but only each have a profile that only works with the cured potting compound cooperates positively.
  • the proposed method enables a considerably more economical production of the key or locking stamp due to the considerably more extensive use of identical parts.
  • the coding part can advantageously only be attached to the base body at its outer circumference.
  • the coding part and the base body can thus initially be guided to one another in the desired angular position and held against one another, and then the corresponding fastening of the coding part on the base body can be effected from the outside in a particularly simple manner.
  • the two components can form a circumferential groove on the outside so that the groove edges are created by these two components and so that, for example, adhesive can be received in the groove, with which the two components are then firmly connected to one another.
  • the adhesive is not added flat between the two components, but only on the outside of the edge, supports a particularly precise alignment of the coding part on the base body, in that the coding part cannot float on an adhesive film and possibly shift in an undesirable manner. before the adhesive has hardened.
  • the addition of adhesive to the contact surfaces of the coding part and the base body can also be provided in a way deviating from the outer circumference, in order to provide the largest possible bonding surface and thus a mechanically highly resilient fastening of the coding part to the To enable basic body.
  • connection of the coding part and the base body is made by welding
  • this fastening can also be limited to the outer circumference of the two components, because the welding enables on the one hand, even if it is only done on the circumference, a mechanically highly resilient fastening of the coding part on the base body, and for The second can
  • Both components are designed as simply and economically as possible, for example as solid blocks or discs or pegs, so that the contact surfaces, when they are in contact with one another, are only accessible from the outside anyway, especially if these contact surfaces are both smooth-surfaced and there are no gaps between them the two components result.
  • the welding of the two coding parts can advantageously be carried out by means of laser welding.
  • the laser beams with a very small diameter to be set precisely also make places accessible on the two contact surfaces that are spaced from the outer circumference, for example if one or both contact surfaces are profiled, so that in this case not only on the outer circumference, but also further fastening points can be created between the coding part and the base body towards the center of the contact surfaces.
  • the coding part and the base body each have smooth-surfaced contact surfaces and a seam line is only present around the circumference on the outer circumference, then the laser welding enables a very precise weld seam, over which the two adjacent components are hardly heated and are accordingly protected from distortion.
  • the thermal load caused by the weld can also advantageously be kept as low as possible in that the weld takes place in the form of a spot weld by means of a plurality of individual weld points.
  • the two components in the form of the base body and the coding part can be connected to one another by means of a single type of connection get connected. It can, however, be provided to combine two or more types of connection, for example both to glue the components together and additionally by means of a weld seam or one or more weld points.
  • the bond enables a gap to be sealed between the two components, and the welding can, as an additional safeguard, reduce the mechanical stress on the bond.
  • gluing or welding can also be provided.
  • a centering aid can advantageously be provided, which facilitates the implementation of the proposed method.
  • a centering aid can advantageously be designed in the form of a circumferential collar, which is provided on a component, namely either on the coding part or on the base body, and overlaps the other component circumferentially, so that the corresponding component is reliably secured against displacement in all radial directions of movement and is thus centered.
  • the drawings show a base body 1, which is designed purely by way of example as a cylindrical pin and is only partially shown. It can be the base body 1 either a key or a locking stamp.
  • the base body 1 is connected to a coding part 2.
  • the coding part has a coding surface 3, which is designed as a stepped end face of the coding part 2 and has been produced by a Z-shaped separating cut, in which a complementary second coding part has also been produced at the same time, so that one of the coding parts 2 can be assigned to the key and the other of the two coding parts 2 can be assigned to the locking stamp of the lock.
  • the coding part 2 shown has a contact surface 4 opposite the coding surface 3, which contact surface 4 is applied to an opposite contact surface 4 of the base body 1 during the manufacture of the key or locking stamp.
  • both contact surfaces 4 are designed to be smooth, so that full-surface contact of the two contact surfaces 4 on one another is made possible. Due to their smooth surfaces, the abutting contact surfaces 4 allow the coding part 2 to be rotated as desired about a central axis 5, which is shown in dashed lines and runs through the base body 1 and the coding part 2, so that this rotational mobility allows the coding part 2 to be in any rotational position on the base body 1 can be created.
  • the coding part 2 has a circumferential collar 6 which serves as a centering aid and whose inner diameter corresponds to the outer diameter of the base body 1.
  • the two adjacent components are fixed in this position and connected to one another by being welded to one another along their circumference by means of a laser.
  • the laser weld seam is created between the collar 6 and the base body 1.
  • the collar 6 runs around the entire circumference of the coding part 2 and is not only designed in the form of individual centering fingers or the like, the weld seam produced creates a tight connection between the coding part 2 and the base body 1, so that, for example, neither moisture nor dirt can penetrate between the two components and the parting line that results between the base body 1 and the coding part 2 is closed over its full length.
  • the stability of the fastening with which the coding part 2 has been fixed to the base body 1 is maximized in this way.
  • Fig. 2 shows a second embodiment.
  • the collar 6, by means of which the coding part 2 and the base body 1 overlap, is provided flush on the outside of the coding part 2 and extends at a distance from the base body 1, so has no guiding or centering function.
  • a centering aid is provided in order to align the coding part 2 precisely with the base body 1.
  • the centering aid is designed as a circular pin 7 on the contact surface 4 of the base body 1 and as a circular bore 8 on the contact surface 4 of the coding part 2, which guides the pin 7 in the radial direction, but allows these two components to be in any desired angle of rotation.
  • the coding part 2 has a circumferential first annular groove 9 in the inner surface of its collar 6 directed towards the base body 1, and the base body 1 has an externally circumferential, second annular groove 10 in the area in which it dips into the collar 6.
  • the annular grooves 9 and 10 are only examples of profiles that create projections or undercuts in the direction of the central axis 5.
  • a potting compound 11 has been poured into the gap between the base body 1 and the coding part 2 and also fills the annular grooves 9 and 10. After it has hardened, it ensures that the coding part 2 and the base body 1 are connected to one another in a tensile manner, that is to say cannot be pulled apart in the axial direction of the central axis 5. Although the coding part 2 and the base body 1 do not have a form fit that would connect them to one another with tensile strength, the potting compound indirectly creates such a form fit, even if it does not adjoin the coding part 2 or the base body 1 in a force-locking manner as an adhesive.
  • the potting compound therefore preferably has a high mechanical stability with regard to its resilience to tensile and shear forces and can for example consist of a corresponding plastic or of a material which is commercially available as so-called cold metal, liquid metal or metal from the tube.
  • Fig. 2 shows a profile in the axial direction, namely by the circumferential annular grooves 9 and 10 shows Fig. 3 a profiling of the base body 1 and the coding part 2 in the direction of rotation, namely by axially extending first projections 12 on the base body 1 and also axially extending second projections 14 on the coding part 2.
  • the base body 1 and the coding part 2 are positively rotatably connected to each other
  • the coding part 2 and the base body 1 do not have a form fit directly with one another, but this form fit is created indirectly, namely by the potting compound.
