Definitions

  • the present invention relates to a locking cylinder comprising a housing assembly with at least one core receiving bore, a core assembly rotatably mounted in the at least one core receiving bore, core-side locking means movably received within the core assembly for interaction with housing-side locking means and a receiving channel within the core assembly for receiving a control member Locking means, wherein the core assembly has a bearing body, which is mounted with a cylindrical outer circumferential surface on a cylindrical inner circumferential surface of the core receiving bore, and wherein axial securing means are produced separately from it, which protrude beyond the outer circumferential surface in the radial direction and the axial fixing of the core assembly within the Serve core receiving hole.
  • a core assembly comprises a bearing body, which is provided at an end portion remote from a control member receiving end thereof with a radially projecting circumferential flange in order to secure the bearing body and thus the core assembly against being pulled out of the core receiving bore.
  • a lock cylinder for a steering wheel lock of a vehicle is known from European patent application EP-A-0 049 051.
  • the core assembly has a bearing body which, in one of its end sections, has a radially projecting circumferential flange integrally formed thereon in order to fix the bearing body within the corresponding core receiving bore against displacement in one direction.
  • this object is achieved in a locking cylinder of the type described in the introduction in that in an end region of the core assembly from which the control member can be inserted into the control member receiving channel, hereinafter referred to as the entry-side end region, on the bearing body a core plate separately produced from the bearing body by in Axial direction positive connection means is attached.
  • a cylindrically shaped blank can then be used for the bearing body, the radial dimension of which already corresponds to the maximum radial dimension of the bearing body. There are therefore no machining operations required for the bearing body, to turn it off in the area of its outer peripheral surface, as is the case with the prior art.
  • the bearing body can be made in a cost-effective manner from, for example, a drawn material, such as. B. brass or the like., Are made.
  • a radial dimension of the core plate can be greater than the maximum radial dimension of the bearing body in order to provide first axial securing means at the end region on the insertion side. Since the boundary plate between the outer circumferential surface of the bearing body and the inner circumferential surface of the core receiving bore can be covered to the outside by the core plate projecting radially beyond the maximum radial dimension of the bearing body, the penetration of dust and dirt or the like into the locking cylinder according to the invention is made more difficult on the one hand and on the other hand manipulation of the locking devices in this border area from the outside is almost impossible.
  • the positive connection means are secured against decoupling by accommodating them within the core receiving bore, it is ensured that after assembling the locking cylinder according to the invention, removal of the core plate from the bearing body without removing the entire bearing body from the core receiving bore is practically impossible.
  • the security provided by the locking cylinder according to the invention can thereby be further increased.
  • the form-fitting connection means can be brought into a connection state in a simple manner by a sliding movement which is essentially orthogonal to the axis of the core assembly.
  • profile means which engage in a form-fitting manner on the core plate and on the insertion-side end region are attached.
  • the interlocking profile means can be formed by a dovetail outer profile and by a dovetail inner profile. This configuration of the profile means further ensures that the core plate cannot be pulled off the bearing body in the axial direction.
  • the two sections of the dovetail inner profile encompassing the dovetail outer profile would first have to be bent radially outward. However, this is not possible if the profile means are arranged within the core receiving bore.
  • the dovetail outer profile can be provided on the bearing body and the dovetail inner profile can be provided on the core plate.
  • the core plate has a passage slot for the control member, which, in the case of the control member being formed with a profiled key shaft, passes through the key shaft profiles of a group of control members adapted to the respective lock cylinder type granted.
  • the passage slot has a polygonal profile, preferably an elongated rectangular profile, which forms an envelope in the axial projection for the profiling of the control organ receiving channel that occurs with the respective locking cylinder type
  • a single type of core plates can be used for different locking cylinders, regardless of the respective one Training of the steering body.
  • this reduces the manufacturing costs of the locking cylinder according to the invention, on the other hand, the storage costs are significantly reduced.
  • the core plate can be provided with an identification feature. This enables, for example, by identifying a group of locking cylinders with core parts, which have the same identification feature, after installing the locking cylinder group, for example in a house, to identify this group by looking at the core plate and thus to select the key suitable for this group in a simple manner . Since only different core plates with different identification features are required to identify the different locking cylinders and no further components of the locking cylinders have to be designed differently for identification, the manufacturing and storage costs are significantly reduced for the manufacturer of such locking cylinders.
  • the core plate at least z. T., but in any case in the area of the passage slot for the control element, consists of a material which is harder than the material of the bearing body, in particular hard metal.
  • the extension of the harder material of the core plate in the axial direction, at least in the adjoining area to the passage slot, is preferably dimensioned such that it cannot engage in a screw groove of a conventional thread available for demolition tools.
  • insert parts made of a material which is harder than the material of the bearing body, preferably hard metal, are provided are.
  • the insert parts ensure that, on the one hand, screwing a screw or tool into the core assembly is made more difficult and, on the other hand, the grip between the screw or tool and the core assembly is not sufficient to pull out the Lock cylinder required force to transfer to this.
  • the insert parts are received in mutually facing partial recesses of the bearing body and the core plate, which complement each other to form an outline that essentially corresponds to the outline of the respective insert part.
  • a force-transmitting connection which is positive in the axial direction and which is caused by radial displacement of the core plate relative to the bearing body can be produced, the partial recesses run essentially parallel to the direction of displacement producing the connection.
  • a circumferential groove for receiving a clamping ring element is provided in an end region thereof opposite the insertion-side end region of the bearing body, the radial dimension of which is larger than the maximum radial dimension of the bearing body.
  • the lock cylinder according to the invention can, for example, be a double lock cylinder, in particular a double lock cylinder with a lock cylinder housing produced in one piece.
  • a circumferential groove is provided in the outer circumferential surface of the bearing body in an end region thereof opposite the insertion-side end region of the bearing body, for receiving a clamping ring element, the radial dimension of which is greater than the maximum radial dimension of the bearing body for forming second axial securing means.
  • the bearing body has the maximum radial dimension in the area of its outer peripheral surface.
  • the present invention further relates to the provision of intermediate products for the production of locking cylinders, the core assembly of which comprises a bearing body and a core plate produced separately from the bearing body, whereby in the course of this intermediate product storage on the one hand dimensionally identical bearing bodies with different locking devices on the core side and on the other hand core plates are kept in stock, the core plates being kept in stock different identifiers, e.g. B. tint.
  • the type of intermediate product storage according to the invention makes it possible for the manufacturer of locking cylinders to identify different locking cylinders or different groups of locking cylinders with a unique identification feature in a simple and cost-effective manner.
  • the identification feature can be, for example, the color of the core plate, which then corresponds to the color of a control element suitable for opening the locking cylinder.
  • the manufacturer of lock cylinders therefore only has to keep different core plates in stock for such a identification of lock cylinders, which can then all be used for a single lock cylinder type.
  • a locking cylinder generally designated 10 is shown.
  • the lock cylinder 10 is of the double lock cylinder type, which is used, for example, in house or apartment doors which must be lockable from both sides. It is pointed out, however, that the present invention can also be embodied in a simple-type locking cylinder which is used, for example, in cabinet doors or the like, which only has to be lockable from one side.
  • the locking cylinder 10 comprises a housing assembly 12, in each of which core receiving bores 14, 14 'are formed for receiving respective core assemblies 16, 16'. Furthermore, the housing assembly 12 includes respective tumbler sections 18, 18 '. In the tumbler sections 18, 18 ', housing-side tumbler means 20 are arranged in a manner known per se, which cooperate with corresponding core-side tumbler means 22 for locking the corresponding core assembly 16 within the core receiving bore 14 against rotation about an axis A. In Fig. 1, the respective tumbler means 20 and 22 in the left housing assembly section are shown schematically only by dashed lines. As is known to the person skilled in the art, the locking devices can include, for example, pin tumblers. More than the two pairs of locking devices shown in FIG. 1 can also be provided.
  • the core assembly 16 comprises a bearing body 24 which is inserted into the core receiving bore 14.
  • An outer diameter of the bearing body 24 corresponds essentially to an inner diameter of the core receiving bore 14, so that the bearing body 24 is arranged within the core receiving bore 14 essentially without play.
  • a receiving channel 26 is provided in the bearing body 24 in which a control member, from an insertion-side end region 28 of the bearing body 24, For example, a key or the like can be inserted in order to interact with the locking means in a manner known per se.
  • a core plate 30, which is produced separately from the bearing body 24, is provided with the bearing body 24 in a manner described in more detail below.
  • the core plate 30 has a section 32 which projects radially over the outer circumference of the bearing body 24 and which is received in a corresponding section of the core receiving bore with a larger inner diameter.
  • the core plate 30 thus prevents through its portion 32 with a larger diameter that on the one hand the boundary area between the outer peripheral surface of the bearing body 24 and the inner peripheral surface of the core receiving bore 14 is accessible from the outside for manipulation by a suitable tool and on the other hand makes it more difficult for dirt to enter the locking cylinder .
  • the core plate 30 with its section 32 forms first securing means for securing the bearing body 24 within the core receiving bore 14 against axial displacement into the core receiving bore 14.
  • the core plate 30 has a passage slot 34 corresponding to the receiving channel 26 of the bearing body 24, in order to allow the corresponding control member to be inserted from the outside.
  • the bearing body 24 In the area of its opposite end 36, the bearing body 24 has a circumferential groove 38, as can be seen in particular in FIG. 2.
  • this circumferential groove 38 of the bearing body 24 lies in a cut-out area 40 of the housing assembly 12.
  • the core assembly 16 is coupled in a manner known per se to a lock bit 44.
  • the locking bit 44 is also rotated about the axis A and thereby actuates corresponding locking elements in a door or the like.
  • FIG. 2 shows how the core plate 30 is connected to the bearing body 24.
  • the bearing body 24 has a dovetail outer profile 46 in its end region 28 on the insertion side on an end face 25 facing the core plate 30.
  • the core plate 30 has a dovetail inner profile 48 in its end face 31 facing the bearing body 24.
  • the sections of the dovetail inner profile 48 of the core plate 30 which encompass the dovetail outer profile of the bearing body 24 would have to be bent outward in the radial direction in order to to be able to slide off to radially outer portions of the dovetail outer profile 46.
  • this is not possible due to the narrow mounting of the bearing body 24 and the core plate 30 within the core receiving bore 14.
  • profile sections can also take other forms, such as. B. T-shaped outer and inner profile shapes.
  • outer profile section can be provided on the core plate and the inner profile section on the bearing body.
  • a pair of insert parts 50, 52 is provided in the region of the transition between the bearing body 24 and the core plate 30.
  • recesses 54, 56 and 58, 60 running transversely to the axial direction A are provided in the core plate 30 and in the bearing body 24.
  • these depressions form corresponding channels in which the insert parts 50, 52 are received.
  • the insert parts 50, 52 are arranged directly adjacent to the receiving channel 26 in the bearing body 24 or the slot 34 in the core plate 30.
  • the insert parts 50, 52 also extend transversely to the axial direction A along the entire depth of the receiving channel 26 or the slot 34.
  • the insert parts 50, 52 serve to prevent a screw or a thread-cutting tool from entering the receiving channel in a manner known per se 26 can be screwed in to pull the entire locking cylinder 10 out of its anchoring by applying a correspondingly large pulling force.
  • parts made of very hard materials for example hard metal or the like, are used for the insert parts 50, 52. If an attempt is then made, for example, to screw a screw into the receiving channel 26, the thread of the screw cannot be inserted into the insert parts 50, or cannot be inserted to a sufficient depth, due to the hard material of the insert parts 50, 52. Cut 52 to provide the force required to pull out the lock cylinder.
  • the extension of the insert parts 50, 52 in the direction of the axis A is chosen so that it is longer than the thread pitch of such screws or tools. It can thus also be avoided that, when the screw is screwed in, it completely engages behind the entire insert parts 50, 52 in the direction of the axis A with one revolution and can thus establish a positive connection with them.
  • the core plate As an alternative or in addition to the insert parts 50, 52 shown, it is possible to manufacture the core plate from very hard material, for example from hard metal, at least in the region of the slot 34. This in turn offers the same advantages as the use of the insert parts 50, 52. Here, too, it is advantageous if the extension of the core plate 30 in this area is greater in the axial direction than the thread pitch of the screws or tools used to break open locking cylinders.
  • a blank made of drawn material for example made of brass, can be used for the bearing body 24, for example.
  • This blank then only needs to be cut to the correct length.
  • the recess 38 has to be provided for the ring element 42.
  • Further shaping steps in the area of the outer peripheral surface such as. B. turning off the blank to provide a radial peripheral flange, as is required in the prior art, are then not necessary here. This leads to a considerably simpler and more cost-effective production of the core assembly 16, since on the one hand fewer work steps are required to manufacture it and on the other hand a blank with a smaller diameter can be used.
  • the core plate 30 can also be cut off from a corresponding cylindrical blank, whereupon the dovetail inner profile and the gradation must be provided in its outer area.
  • the core plate 30 has a significantly smaller axial extension compared to the bearing body 24, the material loss when turning off the outer peripheral surface of the core plate is significantly less than in the case in which the entire outer peripheral surface of a bearing body would have to be turned off.
  • the lock cylinders according to the invention provide manufacturers of such lock cylinders with a simple possibility of marking different lock cylinders or different groups of lock cylinders by selecting specially marked core plates.
  • the core plates selected for marking or identification can have different colors, which then each correspond to the color of the key or the like, which can be used to actuate the corresponding locking cylinder or the corresponding group of locking cylinders.
  • the manufacturer only has to keep differently marked core plates in stock.
  • the components otherwise required for assembling a locking cylinder can then be used in the same way for all locking cylinders or groups of locking cylinders to be assembled. On the one hand, this significantly reduces storage costs and, on the other hand, leads to considerable flexibility in the marking or identification of the locking cylinders.
  • the slot 34 in the core plate 30 can be designed such that its cross-sectional area is substantially independent of the Cross-sectional area of the receiving channel 26 is formed. This can be obtained, for example, by making the cross-sectional area of the slot 34 essentially rectangular, in which case the circumferential line of the cross-sectional area of the slot 34 then essentially forms an envelope for all possible cross-sectional configurations of the receiving channel 26.
  • the core plate can thus be used for a wide variety of locking cylinders, regardless of the cross-sectional shape of the keys or control elements used.
  • the invention provides a locking cylinder which can be manufactured considerably more easily and cost-effectively than known locking cylinders, but which, due to the special design of the connection between the core plate and the bearing body and the provision of the insert parts or the material selection of the core plate, is given greater security against being broken open becomes. Furthermore, when assembling the lock cylinders according to the invention, the entire lock cylinder can be marked only by selecting a correspondingly marked core plate or a group of lock cylinders can be marked in the same way. The manufacturers of such locking cylinders only have to keep differently marked core plates in stock, which can also reduce storage costs.
  • the core assembly 16 can be manufactured in the following manner.
  • the bearing body 24 is cut from a rod.
  • the rod can e.g. B. be formed by a rod or wire drawing process, by rolling, by extrusion, by casting or by continuous casting, it must be ensured in any case that the smoothest possible cylindrical surface is obtained in the rod production, which meets the usual precision requirements in the Manufacture of surfaces from Bearing bodies 24 corresponds.
  • the rod is produced by one of the methods mentioned in a diameter which corresponds to the inner diameter of the core receiving bore 14. No substantial machining is therefore necessary to form the bearing surface of the bearing body 24. At most, a fine treatment is carried out in which there is no significant material removal from the rod section.
  • the rod section obtained in this way is then provided with the receiving channel 26; this process takes place in a conventional manner, for example by drilling and subsequent broaching.
  • the circumferential groove 38 is further screwed into the bearing body.
  • the dovetail outer profile 46 is produced by milling. This dovetail outer profile can be continuous in the radial direction over the entire diameter of the bearing body 24. This solution is preferred in terms of manufacturing technology. But it is also conceivable that the dovetail outer profile 46 opens out only on one side into the bearing surface of the bearing body 24 and ends at a diametrically opposite location in front of the outer peripheral surface of the bearing body 24, so that a stop is formed there. The importance of the stop will be discussed below when considering the manufacture of the core plate 30.
  • a conventional material for example brass or a relatively soft steel, can be used to produce the bearing body 24.
  • the core plate 30 can be obtained by machining a round, disc-shaped blank or by sintering.
  • the dovetail inner profile 48 can extend continuously over the entire diameter of the core plate 30 in the diametrical direction. This applies in particular if the dovetail outer profile 46 also extends in the diametrical direction over the entire diameter of the bearing body 24.
  • the continuous formation of the dovetail inner profile 48 is advantageous in terms of production technology, for example using a milling cutter. But you can also do that Form dovetail inner profile 48 so that it extends from the circumferential surface of the core plate 30 only over part of the diameter of the core plate 30.
  • a counterstop can be created which interacts with the abovementioned stop formed on the dovetail outer profile 46 and defines the position of the core plate 30 relative to the bearing body 24.
  • the core plate 30 can be pushed into the correct radial position to the axis of the bearing body 24 before installation in the housing 12 and can be temporarily held in this by a stop until the two parts 24 and 30 are pushed together into the housing 12 and thus relatively are fixed to each other with respect to their axis position.
  • both the dovetail inner profile 48 and the dovetail outer profile 46 are made to be continuous in the diametrical direction, one can think of a pre-assembly of the core plate 30 on the bearing body 24, for example by a clamp fit of the dovetail inner profile 48 to make the dovetail outer profile 46 or by gluing.
  • the depressions 54, 56; 58, 60 can be attached continuously to the core plate 30 and to the bearing body 24, in such a way that they extend parallel to the profile profile of the dovetail outer profile 46 or the dovetail inner profile 48.
  • the insert parts 50, 52 can be inserted after the core plate 30 and the bearing body 24 have been assembled. This is a preferred solution for the machining of the core plate 30 and the bearing body 24.
  • the recesses 54 and 58 could be arranged in the core plate 30 so that they are closed at both ends. Then you can insert parts 50 and 52 into the recesses 54th and insert 58 before the core plate 30 is assembled with the bearing body 24. The prerequisite is, of course, that the recesses 56 and 60 are then open at least at one end in the diametrical direction.
  • the assembly could also be facilitated in that the insert parts 50, 52 are clamped or preferably glued to one of these parts before the parts 30 and 24 are assembled. It is preferred to glue the insert parts 50, 52 to the core plate 30. In this way, the assembly of the parts 30 and 24 and the storage of the parts is facilitated, since in total only two parts 30 and 24 have to be kept in stock, one of which is already permanently connected to the individual elements 50 and 52. If the insert parts 50 and 52 are firmly connected to the core plate 30 by gluing or jamming, the recesses 56 and 60 must of course in turn open at one of their ends in the outer circumferential surface of the bearing 24 so that the core plate 30 on the bearing body 24 in diametrical direction can be postponed.
  • the manufacturing and assembly process also include essential features of the invention. It is of particular importance here that the bearing body 24 is manufactured without substantial machining of its cylindrical bearing surface serving for storage in the receiving channel 26.
