Definitions

  • the invention relates to a locking cylinder comprising a locking cylinder housing with an outer surface and a core receiving bore, a locking cylinder core rotatably received in this core receiving bore with a key insertion slot for receiving a key, and at least one pair of locking pins, said locking pin pair being a core pin bore guided in a core pin bore of the locking cylinder core and a core pin bore of the lock cylinder housing guided housing pin, which pins are aligned with one another in a basic position of the lock cylinder housing relative to the lock cylinder housing and, with the key adapted to the lock secret, being adjusted by pretensioning means in such a way that a mutually facing end parts of the core pin and the housing pin lie in the cylindrical separating surface between the core and the receiving hole on the core Lock cylinder core lies and where the Genzo Usestattbohrung cuts a surface area of the outer surface of the lock cylinder housing and is closed by a closure means.
  • Such a lock cylinder is known for example from German patent 33 38 713.
  • a plurality of tumbler pin pairs are arranged one behind the other in the direction of the longitudinal axis of the locking cylinder, the housing pin bores being accommodated in the web part of a so-called cock profile of the locking cylinder housing.
  • the closure means for closing the housing pin bores are formed by grooved pins, which in the outer ends of the housing pin bores, i.e. the ends of the housing pin bores opening in the area of the sack bottom surface of the profile web are pressed in.
  • the ends of the notch pins in the area of the bag bottom surface are machined so that they completely complement the cylindrical bag bottom surface in accordance with their cylindrical shape.
  • the closure means has a convex end surface which is rotationally symmetrical with respect to an axis of the housing pin bore and seen from the outer space surrounding the outer surface, the end surface of which is orthogonal to the axis of the housing pin bore
  • Large cross-section lies on its entire circumference within the housing pin bore and the apex of which is preferably at or at a small distance within a virtual partial area of the respective surface area delimited by the housing pin bore, which corresponds to a partial area of the surface area removed when the hole is drilled.
  • the remaining ring recesses which increase in depth from the apex area to the circumferential surface of the housing pin bores, are so small that there is no fear of chips and similar impurities getting caught to a greater extent.
  • the locking cylinder designed according to the invention feels almost as smooth and touch-friendly as a locking cylinder in which the locking means are smoothly adapted to the respective surface area.
  • the end surface can be a spherical end surface with a diameter that approximately corresponds to the diameter of the housing pin bore.
  • the closure parts can be produced in such a quality and in particular such a hardness that they are not damaged when they are introduced into the housing pin bores, however this is carried out, and therefore their appearance is not impaired.
  • the closure elements can be polished at the ends, for example, or otherwise surface-treated, so that they fit well into the surface appearance of conventional galvanized or lacquered locking cylinders, whereby interesting effects can still be achieved through different colors, different glosses or other different surface designs.
  • the fastening of the closure means in the housing pin bores is preferably carried out by pressing in, the diameter of the closure means being matched to the diameter of the housing pin bores in such a way that pressing in is achieved on the one hand without visible deformation of the respective surface area, but on the other hand an immovable retention of the closure means in the housing pin bores is guaranteed.
  • lock cylinder housings are usually made of a non-ferrous metal, steel parts can be used as the closure means, which can be mass-produced cheaply.
  • the proposal for the invention is particularly applicable when the surface area into which the housing pin bores open, is formed by a cylindrical surface, the surface lines of which run parallel to the axis of the core receiving bores. This applies both to round cylinders and to the popular locking cylinders with Hahn profile, in which the housing pin bores cut the sack bottom surface of the profile web of the Hahn profile.
  • the closure means is formed by a ball.
  • the advantage of this embodiment is that the automatic feeding in an automatic manufacturing machine can be carried out using balls without complicated orientation means.
  • balls as a closing means is to be regarded as unusual because when using balls there is no freedom of variation with regard to the axial depth of the closing means ball, in order to be able to adapt to different cylinder shapes, different preloading means and different housing pin dimensions.
  • this has surprisingly proven to be harmless because there is the possibility of varying the respective free length of the housing pin bore by introducing fillers into the housing pin bore, so that the prestressing means can then be supported on such fillers if necessary.
  • balls or cylinder sections can be used as packing.
  • the closure means may be formed by a rod which has the rotationally symmetrical convex end face at at least one end, preferably both.
  • the assembly technology is complicated by such a measure compared to a ball, however, so that this option will only be used in special situations, for example when special profiles of the spherical end faces are to be selected.
  • an annular shoulder is also provided at the transition from the rod to the convex end face. In this way, the maximum cross section of the convex end surface can be smaller than the cross section of the cylindrical section of the rod-shaped closure means.
  • the biasing means can be formed by helical compression springs. It is advantageous if the helical compression spring for positioning has an enveloping surface at least over part of its length, the diameter of which corresponds at least approximately to the inside diameter of the housing pin bore. To prevent the helical compression spring from incorrectly adjusting or jamming against a convex surface of the closure means in the gap formed between the circumferential surface of the housing pin bore and the convex end surface, it may be advantageous if the helical compression spring is at least at the end in contact with the spherical surface has a tapered section.
  • the invention further relates to a method for producing a locking cylinder, said locking cylinder comprising a locking cylinder housing with an outer surface and a core receiving bore, a locking cylinder core rotatably received in said core receiving bore with a key insertion slot for receiving a key and at least one pair of locking pins, said locking pin pair one in a core pin bore Locking cylinder core-guided core pin and a housing pin guided in a housing pin bore of the locking cylinder housing, which pins are aligned with one another in a basic position of the locking cylinder core with respect to the locking cylinder housing and, when the key, which is adapted to the locking secret, is inserted, are set by pretensioning means such that a separating end pin and separating end pin parts are located between the core pin in the cylindrical interface between the core receptacle bo and the locking cylinder core, and wherein the housing pin bore cuts an area of the outer surface of the locking cylinder housing and is closed by closure means, this method comprises a drilling operation starting from the surface area cut through
  • a closure body be inserted as a closure means into the housing pin bore, which at least at its end trailing during insertion has an end surface that is rotationally symmetrical with respect to an axis of the housing pin bore and that is convex as seen from the outer space surrounding the outer surface, whose largest cross-section orthogonal to the axis of the housing pin bore enters the housing pin bore over its entire circumference, while the apex is preferably placed at or at a small distance within a virtual partial area of the respective surface area delimited by the housing pin bore, which part of the surface area is removed when the bore is drilled corresponds.
  • the closure body can be fixed in the housing pin bore by a press fit.
  • the closure body can be inserted through an insertion surface of an insertion tool which determines the insertion depth against the respective surface area.
  • This insertion surface can press in several closure means at the same time, so that their uniform positioning is ensured.
  • closure body is inserted into the housing pin bore after the housing pin and possibly the pretensioning means and / or a filler body have been inserted through the outer end of the housing pin bore associated with the surface area.
  • the housing pin and possibly a filler and / or a pretensioner may be inserted into the housing pin bore from the core pin bore after the outer end of the housing pin bore facing the surface area has been closed by inserting the closure body.
  • the decision about which of the two options is chosen also depends in particular on the existing manufacturing facilities.
  • the resulting bore is preferably only made up to the intersection with the core pin bore, so that the area of the cylinder housing diametrically opposite the housing pin bore is not cut and therefore does not have to be closed again.
  • the lock cylinder housing of a double lock cylinder is generally designated 10.
  • This lock cylinder housing has a so-called Hahn profile with a profile web 12, the bag bottom surface of which is designated 14.
  • the lock cylinder 10 also has a core bore 16 which receives a lock cylinder core 18 with a key insertion slot 20.
  • This tumbler pin pair 22 consists of a core pin 22a and a housing pin 22b.
  • the core pin 22a is received in a core pin bore 24a of the lock cylinder core 18, while the housing pin 22b is received by a housing pin bore 24b of the lock cylinder housing 10.
  • the core pin 22a and the housing pin 22b are aligned with one another.
  • the separation point 22c between the core pin 22a and the housing pin 22b is, when a key adapted for a locking secret is inserted, in the separation surface 28, which is defined by the inner peripheral surface of the core bore 16 and the outer peripheral surface of the lock cylinder core 18. If the separation points of all the pairs of pin cylinders lie in the separation surface 28, the lock cylinder core can be rotated by means of the key.
  • the housing pin bore 24b is drilled from the bag bottom surface 14 into the lock cylinder housing 10 until it intersects with the core bore 16.
  • the lower end of the housing pin bore 24b is closed by a locking ball 30 with an end surface 30a which is pressed into the housing pin bore 24b with a slight oversize.
  • the locking balls 30 of the individual housing pin pairs can be pressed in by a common tool 32, which is shown in FIG.
  • This housing has a thrust surface 34 which is precisely adapted to the sack bottom surface 14 and which, when the tool 32 approaches the sack bottom surface 14, bears against it and thereby brings the balls 30 into a position in which their apex regions S pointing downward each have a virtual surface V lie, which complements the bag bottom surface 14 with a corresponding curvature.
  • the upper and lower ends of the helical compression spring 38 are wound closer than the middle section, so that these end sections find a defined contact with the filling ball 36 and the lower end of the housing pin 22b.
  • the housing pin pairs can have different shapes as indicated in the figure.
  • the separating point 22c which with the key fitted to the secret, is adapted must lie in the separating surface 28, does not necessarily have to be formed by the facing ends of the pins 22a and 22b themselves, but can also be formed by one of these pins and an intermediate plate which can be used in varying thicknesses for the closure variation.
  • the separation point can also be formed between two adjacent intermediate plates (not shown).
  • Lock cylinder core 18 and lock cylinder housing are manufactured separately.
  • the lock cylinder core is provided with the bores 24a.
  • the housing pin bores are drilled from the sack bottom surface 14 until the respective drilling instrument enters the core bore 16.
  • the locking cylinder core 18 is then fitted with the core pins 22a and inserted into the core bore 16, wherein it is rotated relative to the basic position according to FIG. 1.
  • the housing pin 22b, the helical compression spring 38, the filling ball 36 and the closure ball 30 can be inserted one after the other through the housing bore 24b.
  • the housing pin 22b enters the core pin bore 24a.
  • FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 only in that 36 filler pins 136 are provided instead of the filler balls.
  • the length of the cylindrical filler pins can be predetermined in accordance with the respective space requirement.
  • locking pins can also be used (not shown in the drawing) which have a convexly curved, in particular spherical, end face at at least one end. Such locking pins are preferably made at both ends with identical convex surfaces in order to simplify the automatic feeding.
