Definitions

  • the invention relates to a locking cylinder comprising a locking cylinder housing with an axis, a locking cylinder core rotatably received in an axially parallel, hollow cylindrical bearing surface of the locking cylinder housing with a key channel for receiving an adapted key and at least one cylindrical locking pin guided in a guide of the locking cylinder core in an approximately axis-normal plane with a dome-shaped end surface remote from the key channel, the end near the key channel can be controlled by a level-varying side surface of the key and the dome end surface remote from the key channel with a single recess arranged on the bearing surface of the lock cylinder housing cooperates cam-like in such a way that the locking pin rotates when the lock cylinder key is turned by means of the key can be disengaged from the single recess.
  • EP-A-0 237 799 discloses such a locking cylinder, in which the end surface of the locking pin remote from the key channel has the shape of a hemisphere and the individual recess has the shape of a spherical cap adapted to the hemisphere.
  • the inner peripheral surface of the dome-shaped individual recess lies completely against the hemispherical end surface of the locking pin.
  • the above object is achieved in that the contour of the individual recess located in the bearing surface protrudes in at least one circumferential direction of the bearing surface in at least one circumferential direction of the bearing surface when the locking pin is aligned with the individual recess and the dome-shaped end surface is immersed in the individual recess and increases with increasing Has circumferential distance from the locking pin axis decreasing axial width.
  • the proposed solution ensures that the rotational movement of the lock cylinder core is not hindered during the disengagement of the locking pin from the recess, so that the rotational movement of the lock cylinder core takes place uniformly as soon as the lock cylinder is actuated by means of the adapted key. It is nevertheless still ensured that the individual recess together with the locking pin reliably prevents rotation of the lock cylinder core when an attempt is made to actuate the lock cylinder by means of an unmatched key.
  • the contour of the individual recess in the bearing surface can have very different shapes.
  • the contour of the individual recess located in the bearing surface is preferably diamond-shaped with a diamond diagonal running in the circumferential direction of the bearing surface. This ensures that independent the position of the individual recess, with respect to the longitudinal axis of the locking cylinder, does not hinder the rotary movement of the locking cylinder core in both circumferential directions of the bearing surface.
  • An ellipse, the main axis of which runs in the circumferential direction of the bearing surface, would also be conceivable as a further shape for the contour.
  • the contour of the individual recess located in the bearing surface can be produced, for example, in that the individual recess has an essentially prismatic inner peripheral surface.
  • the prismatic inner circumferential surface viewed when the locking pin is aligned with the individual recess, can run essentially parallel to the locking pin axis.
  • the bearing surface can be formed on the one hand by the inner circumferential surface of a bearing bore in the lock cylinder housing. But there is also the possibility that the bearing surface is formed by a non-rotatably inserted sleeve in a bore of the lock cylinder housing.
  • the use of the sleeve has the advantage, on the one hand, that the manufacture of the individual recess, which is relatively difficult to manufacture in the bearing bore of the lock cylinder housing, can take place in one production step before the sleeve is inserted, which simplifies the manufacture of the lock cylinder overall.
  • a different, in particular harder, wear-reducing material can be used as for the lock cylinder housing, which for manufacturing reasons is preferably made of non-ferrous metal, in particular brass, which is much more sensitive to wear than, for example, the steel used for a sleeve.
  • the manufacture of the individual recess can be further facilitated in that the individual recess completely penetrates the wall of the sleeve.
  • the uniform rotational movement of the lock cylinder core when disengaging the locking pin can be supported in that the dome-shaped end surface is formed by an approximately spherical central surface and a conical transition surface connecting the spherical central surface with a cylindrical outer surface, the conical transition surface engaging with the contour of the individual recess . If the contour is diamond-shaped and the locking pin lies with its conical transition surface against this contour, there is only one point contact at four points between the locking pin and the individual recess.
  • further locking devices can be provided in the locking cylinder to increase security.
  • the key chest of the key works together with spring-loaded tumbler pin pairs and that on at least one side, preferably on both sides, of the key channel in the locking cylinder core there are essentially axially normal slots, which optionally have a locking pin or a key-controlled, with further recesses of the Take up bearing surface cooperating double-arm locking lever, which in the case of a locking pin is guided by guide spheres in the side surfaces of the respective slot and, in the case of a double-arm locking lever, it is pivotably mounted about an axially parallel pivot bearing.
  • the slots can be arranged axially offset in relation to the spring-loaded tumbler pin pairs in the lock cylinder core.
  • the locking pin be arranged in a secant plane offset with respect to the axis of the lock cylinder core.
  • the lock cylinder 1 has a lock cylinder core 10 which is rotatably received in a sleeve 12 made of stainless steel.
  • the sleeve 12 is inserted non-rotatably in a lock cylinder housing 14.
  • the inner circumferential surface of the sleeve 12 forms a hollow cylindrical bearing surface 16 for the lock cylinder core 10 which is parallel to the axis of the lock cylinder housing 14.
  • the lock cylinder core 10 has a key channel 18, in which an adapted, not shown key 20 for actuating the lock cylinder 1 is inserted.
  • a plurality of stepped bores 22, which are arranged axially spaced apart from one another, are provided, which have a bore section 22a remote from the key channel and a smaller bore section 22b closer to the key channel.
  • the axes of the bores 22 lie in a secantial plane radially spaced from the axis of the lock cylinder core 10.
  • a cylindrical locking pin 24 is used, which is guided longitudinally in the bore 22.
  • all or only a part of the existing bores 22 can be occupied with a locking pin 24.
  • the cylindrical locking pin 24 has a locking pin portion 24a remote from the key channel and a locking pin portion 24b closer to the key channel and smaller in diameter.
  • the end 24c of the locking pin 24 remote from the key channel has a dome-shaped end surface which is formed by an approximately spherical central surface and a conical transition surface connecting the spherical central surface to the cylindrical outer surface.
  • the end 24c of the locking pin 24 remote from the key channel protrudes into an individual recess 26 which completely penetrates the wall of the sleeve 12.
  • the individual recess 26 has a diamond-shaped contour in the bearing surface 16 with a diamond diagonal running in the circumferential direction of the bearing surface 16.
  • the contour of the individual recess 26 jumps beyond the outline of the immersing locking pin 24 defined by the bearing surface 16 in both circumferential directions and has an increasing circumferential distance from it Locking pin axis decreasing axial width (see. Fig. 2 and 3).
  • the diamond-shaped contour continues through the sleeve 12 so that the individual recess 26 has a prismatic inner peripheral surface. If the locking pin 24 is aligned with the individual recess 26, the prismatic inner circumferential surface runs essentially parallel to the locking pin axis.
  • the end 24d of the locking pin 24 near the key channel enters a key hole 28 in the key 22. If the rotational movement is continued, the locking pin 24 is gradually pushed out of the individual recess 26 due to the diamond-shaped contour of the individual recess 26 located in the bearing surface 16, so that the rotational movement of the lock cylinder core 10 is not hindered.
  • the lock cylinder housing 14 has several in a row axially one behind the other, radially extending housing bores 30, which are each arranged centrally between two successive axial bores 22 stepped bores 22 and receive the spring-loaded housing pins 32.
  • core bores 34 are provided, which are intended to receive core pins 36 and which are aligned with the housing bores 30 in the basic position shown in FIG. 1.
  • the key 20 has a serrated key face 20a, which is intended to arrange the separating surfaces between the housing pins 32 and the core pins 36 in the bearing surface 16 of the sleeve 12 so that the lock cylinder core 10 can be rotated.
  • plates 38 can be arranged between the housing pins 32 and the core pins 36 in order to enable the key cylinder 20a to rotate with different key levels, which can be the case in particular with locking systems.
  • a plurality of axially normal, spaced apart slots 40 are further arranged on both sides of the key channel 18 in such a way that the bore axes of the stepped bores 22 lie in their central longitudinal plane.
  • the locking pins 24 are guided through guide spheres arranged in their side surfaces.
  • the slots 40 are milled with a side milling cutter and have a slot base 40a through which the bores 22 pass (cf. FIG. 1).
  • the slots 40 are penetrated by bearing pins 42 which are parallel to the axis of the lock cylinder core 10 and which are received in corresponding bores in the lock cylinder core 10.
  • Double arm locking levers 44 are mounted on the bearing pins 42, each having two locking projections 44a and 44b, which are attached to arms 44c and 44d.
  • a control pin 46 bears against the arm 44c a control pin bore 48 of the lock cylinder core 10 is slidably mounted. This control pin 46 engages with its key channel end 46a in a further key hole 50 of the adapted key 20.
  • the depth of the key hole 50 is dimensioned taking into account the length of the control pin 46 and the shape of the double-arm locking lever 44 and the locking projections 44a and 44b such that the two locking projections 44a and 44b in a single angular position shown in FIG. 1 are flush with the bearing surface 16 the sleeve 12 lie and the lock cylinder core 10 can be rotated.
  • the arm 44d of the locking lever 44 is loaded by a helical compression spring 52 in the counterclockwise direction, in such a way that when the key 20 is suitable, the locking projections 44a and 44b lie flush with the bearing surface 16 of the sleeve 12.
  • the helical compression spring 52 is received in a bore 53, the diameter of which is greater than the width of the slot 44, so that the lateral contact surfaces of the slot 44 are cut.
  • the locking projections 44a and 44b are opposite locking projection recesses 54a and 54b in the bearing surface 16 of the sleeve 12.
  • the edges of the locking protrusion recesses 54a and 54b are rounded. This is important if the locking pins 24 lie in the same plane as the double arm locking levers 44, so that when the locking cylinder core 10 is rotated by means of the adapted key 20, the locking pins 24 can slide over the edges of the locking projection recesses 54a and 54b without the rotary movement being impeded becomes.
  • slots 40 with four stepped bores 22 and four individual recesses 26 can be provided on one side of the key channel 18, 40 double-arm locking levers 44 being arranged in two slots and 40 locking pins 24 being arranged in the two other slots. But it is also possible that part the slots 40 or the bores 22 remain unoccupied. Of course, other combinations are also conceivable both on one side and on both sides of the key channel 18.
  • a wrong key is used for the locking cylinder 1, ie a key that has no bores 28, 50 and / or is provided with bores 28, 50 that are too shallow or too deep, then one of the two locking projections 44a and 44b respectively Double arm locking lever 44 protrude into the corresponding locking projection recess 54a or 54b and / or the locking pins 24 into the individual recesses 26. This prevents the lock cylinder core 10 from rotating. The same applies if a key is used whose key chest is not suitable for controlling the housing pins 32 or the core pins 36.
  • the sleeve 12 has a slot 58, the boundary edges 58a and 58b of which bear against contact surfaces 14a and 14b of the locking cylinder housing 14, so that the sleeve 12 is fixed non-rotatably in the locking cylinder housing 14.
  • FIG. 2 also shows that the sleeve 12 is covered by a cover plate 60 of the lock cylinder core 10, so that the sleeve 12 is inaccessible and the appearance of the lock cylinder 1 from the front does not differ from conventional lock cylinders.
  • the key 20 on its level-varied side surfaces in addition to the key holes 29, 50 can also have longitudinally extending locking and guide ribs (not shown further), the key channel 18 being provided with corresponding grooves.
