Definitions

  • the invention relates to a lock cylinder with a lock cylinder housing, which has a cock profile, that is, a cylinder profile part and a web profile part adjoining the cylinder profile part in an approximately radial direction, furthermore with a lock cylinder core accommodated in a bore of the cylinder profile part, furthermore with key-operated parts partially accommodated in the web profile part Locking means and with the locking means within the web profile part in the direction of the key entry end of the web profile anti-drilling protection means, the cylinder core protruding with its key input end over the cylinder profile part.
  • Such a locking cylinder is known from a brochure "Winkhaus System - Information" with the print no. 29048 G.
  • Lock cylinders are manufactured in different lengths so that they can be adapted to the respective wall thickness when installed in a door. For safety reasons and for aesthetic reasons, there is a requirement that the lock cylinder housing protrude as little as possible over the side face of the door or over the respective end face of a door plate arranged on the door side face. On the other hand, there is a requirement to accommodate guard locking systems that are as varied as possible and provide high security between the lock cylinder housing and the lock cylinder core. In the case of conventional spring-loaded tumbler pin pairs, this requirement is that as many as possible, for example six such tumbler pin pairs, should be accommodated per lock cylinder core.
  • the length of the web profile part can be increased compared to the length of the cylinder profile part, that is to say that the web profile part can protrude from the cylinder profile part without contradicting the aesthetic and safety requirements, if one protrudes beyond the key protruding end of the cylinder profile part of the web profile part provides chamfers or roundings. In this way, space is created for the anti-drilling devices, which are upstream of the locking devices.
  • the length of the cylinder profile part remains relatively short and, with a corresponding door, does not protrude, or protrudes only insignificantly, over the door side surface or the front surface of the door plate.
  • the length of the web profile part is greater, so that this web profile part protrudes or protrudes further over the door side surface or the door plate end surface.
  • This overhang or larger overhang can - as has been shown - thanks to the existing chamfer or rounding be accepted and brings the decisive advantage that more space is created for the anti-drilling agents in the web profile part.
  • the proposed measure contradicts the previous ideas of the professional world in that it was always considered correct for manufacturing reasons to place the end faces of the cylindrical profile part and the web profile part in a common plane perpendicular to the axis of rotation of the locking cylinder for the sake of joint processing.
  • the projection length of the web profile part with respect to the cylinder profile part is approximately the same or smaller than the projection length of the lock cylinder core with respect to the cylinder profile part. It has been shown that if this rule is observed, the appearance of the built-in locking cylinder is at least equal to the appearance of previous locking cylinders. Since the range of materials in the area of the web profile part is sufficient for large-area rounding or chamfering even when anti-drilling agents are accommodated, the safety requirements regarding the attachment of demolition pliers at the end of the locking cylinder can also be adequately taken into account if there are protrusions of the size provided here.
  • an aesthetically and safety-technically particularly advantageous embodiment provides that the projection of the web profile part is chamfered all around;
  • the projection of the web profile part has an end surface orthogonal to the axis of rotation of the lock cylinder and that this end surface is chamfered according to a heraldic outline of the web profile part along a floor curve, along two substantially straight side edges and along a straight top edge tangentially adjacent to the cylinder profile part.
  • Another aesthetic and also very satisfactory embodiment is based on the fact that the projection of the web profile part has a partially cylindrical end face, the generatrix of which is parallel to the vertical axis of the tap profile.
  • This embodiment can be further improved in that the part-cylindrical end face merges over edges in side faces of the web profile, that the part-cylindrical end face merges with a spherical transition surface into a rounding of the bottom of the web profile part and that the part-cylindrical end face over a chamfer tangent to the cylinder profile part into the end face of the Cylinder profile part merges.
  • the additional space available through the projection of the web profile part can be used so that when the locking device is designed with tumbler pins parallel to the vertical axis of the tap profile, the anti-drilling means are formed by protective pins also parallel to the vertical axis of the tap profile.
  • the protective pins can be arranged in front of a terminal tumbler pin along an arc, in particular in such a way that one of three protective pins is located in the longitudinal center plane of the tap profile and two more are arranged symmetrically on both sides of the longitudinal center plane of the tap profile.
  • the security against the attachment of break-off tools and the aesthetic appearance can be further improved if the projection of the cylinder core is chamfered in the shape of a truncated cone and if the chamfering surface on the one hand into an end surface of the locking cylinder core orthogonal to the axis of rotation of the locking cylinder and on the other hand into one to the axis of rotation of the lock cylinder core orthogonal end face of the cylinder profile part.
  • the existence of the protrusion of the cylinder core, in addition to the protrusion of the bar cylinder part, is also important from a safety point of view insofar as there is hardly any space between a break-off pliers with their upper pliers jaws that spread in the longitudinal center plane of the tap profile and engage the protrusion of the bar profile part the projection of the web profile part and the projection of the cylinder core.
  • the smaller projection of this cylinder profile part and the chamfering of the adjacent cylinder core part also make such chamfering unnecessary.
  • the projection of the lock cylinder core can be used to receive a diametral groove parallel to the central plane of the key slot, which on the one hand facilitates the threading of the key into the key slot and on the other hand is designed to receive a torque transmission part of the key if the key is designed accordingly.
  • This diametral groove can accommodate a thickened torque transmission part of the key that is close to the handle.
  • the protrusion of the lock cylinder core can be formed by an end disk which is radially widened with respect to the main section of the lock cylinder core and is partially received in a depression in the end face of the cylinder profile part on the key entry side. This end plate ensures the axial fixation of the key cylinder core.
  • the lock cylinder core can also be provided with anti-drilling means which lead the locking device to the key entry side End of the lock cylinder core are upstream.
  • anti-drilling means of the lock cylinder core can be formed by protective pins which are arranged in the lock cylinder core approximately parallel to the key slot center plane on both sides of the key slot.
  • the invention can also be applied in particular to double locking cylinders which are actuated from both ends with a key.
  • the value of the configuration according to the invention is particularly important here in view of the greater length requirement.
  • a double lock cylinder is generally designated 10. It comprises a lock cylinder housing 12 with a so-called “tap profile” and a lock cylinder core 14 with a key insertion slot 16. It is a double lock cylinder. A lock cylinder core 14 is also arranged at the other end of the lock cylinder housing. The two locking cylinders act on a locking ring 18 which carries a locking bit 20.
  • the lock cylinder housing is designed for installation in a mortise lock and is provided with a fastening bore 21, so that it can be fixed in the direction of the axis of rotation AA in the mortise lock by means of a screw.
  • the vertical axis of the tap profile is labeled HH.
  • the axis of rotation AA and the vertical axis HH together define the longitudinal center plane of the tap profile, which is referred to below as AH.
  • the lock cylinder housing 10 comprises a cylinder profile part 22 and a web profile part 24.
  • the cylinder profile part 22 has a bore 26 which receives the lock cylinder core 14.
  • the key input-side end of the cylinder profile part 22 is formed by an end surface 28 which merges with sharp edges into the outer peripheral surface 30 of the cylinder profile part.
  • the locking cylinder core 14 has an end disk 32 which is embedded in a recess 34 in the cylinder profile part 22 and is axially fixed.
  • the end disk 32 has a truncated cone-shaped extension 36, which is formed by a truncated cone-shaped chamfer 36a and an end face 36b orthogonal to the axis AA.
  • the frusto-conical chamfer 36a merges into the axially normal end face 28 of the profile cylinder part 22.
  • the web profile part 24 has a projection 38 opposite the end face 28 of the cylinder profile part 22.
  • This projection 38 is designed with an axially normal end face 38a, lateral chamfers 38b, an upper chamfer 38c, which runs perpendicular to the vertical axis and is tangential to the lock cylinder core 14 and with a rounded lower chamfer 38d.
  • the projection has the shape of a coat of arms in the end view.
  • the height of the projection 38 of the web profile part 24 relative to the end surface 28 of the cylinder profile part 22 is approximately equal to the height of the frustoconical chamfer 36a, that is to say approximately the same as the protrusion of the end disk 32 over the end surface 28 or, to put it another way, equal to the distance of the orthogonal end face 36b of the cylinder core from the end face 28 of the cylindrical profile part 22.
  • the faces 36b and 38a are approximately flush.
  • the end surface 28 can lie slightly in front of the side surface 40.
  • An extension of the lock cylinder housing 12 with tearing in the area of the hole 21 is also excluded thanks to this configuration. It is particularly important to note that a tool can hardly be attached to the chamfer 38c because such a tool would have to be inserted into the narrow gap 42 between the chamfer 38c and the chamfer 36a, which is hardly possible.
  • a diametrical slot 44 is milled into the protrusion of the end disk 32 delimited by the frustoconical bevel 36a and the end face 36b, as can be seen from FIGS. 1 and 4, the slot bottom 44a of which lies essentially flush with the end face 28 of the cylindrical profile part 22 and in the region of the Entrance of the key tip to a cone 44b is widened and deepened.
  • the purpose of the protrusion 36a, 36b of the end plate 32 is, inter alia, to provide delimiting parts for the diametrical slot 44 outside the lock cylinder housing, so that the cylinder profile part 22 does not have to be lengthened with regard to the formation of the diametrical slot, that is to say that it is extremely short overall length of the cylinder profile part 22 is obtained, which is adapted to very thin door leaves.
  • FIG. 2 shows a spring-loaded pin tumbler 46, which penetrates into the web profile part 24.
  • a total of 4 or 5 or preferably also 6 such tumbler pin pairs 46 are arranged one behind the other in the direction of rotation AA; the more the dear.
  • the tumbler pin pairs 46 are difficult to accommodate on the respectively available length of the half cylinder.
  • Such a chamfer would conflict with the minimum wall thickness of the cylindrical profile part 22 in the region of the recess 34, while on the other hand in the region of the projection 38 there is sufficient material of the web profile part to provide an optically and safety-related chamfer, for example at an angle of 30 ° to 60 °, preferably about 45 °, against the central axis (not shown) of the projection 38.
  • the right half of the locking cylinder in Figure 2 can be formed in the same way.
  • the lock cylinder core 14 can also be armored against drilling, for example by means of a "corkscrew", for example in that in the disk 32 on both sides of the key insertion slot 16 carbide pins are taken from corresponding holes.
  • a drilling protection is still to be accommodated with full or largely full use of the length dimension required for pin tumblers , without the visual appearance deteriorating and the risk of the possibility of attaching an opening tool stressing the cylinder housing on bending being increased.
  • FIGS. 5 to 8 differs from the embodiment according to FIGS. 1 to 4 only by a different design of the projection 138. Otherwise, analog parts are provided with the same reference numerals as in FIGS. 1 to 4, each increased by the number 100.
  • the projection 138 is formed by a cylindrical surface 138f which merges into the side surfaces 124b of the web profile part 124 via edges 138g.
  • This cylindrical surface 138f merges via the chamfer 138c into the end surface 128 and via a spherical surface 138d into the rounded bottom 124c of the web profile part 124.
  • the effect of this projection formation is essentially the same as results from the comparison of FIGS. 3 and 7.
  • the protrusion of the lock cylinder core with respect to the cylinder profile part and the protrusion of the web profile part with respect to the cylinder profile part is approximately 0.5 to approximately 3.0 in both exemplary embodiments, preferably approximately 1.0 mm to approximately 2.0 mm.
