Definitions

  • the invention relates to a cylinder lock with flat key according to the preamble of the main claim.
  • the link forming the movable beard step is designed as a double lever pivotable about an axis.
  • the back flank of the double lever protrudes over the broad side of the key and is convexly curved. In the inserted end position, this curved back edge runs against the shoulder in the key channel.
  • a lug of the double lever on the opposite broad side of the key is steered, enters the hole for the additional guard locking and arranges it in the release position which enables the cylinder core to be rotated.
  • the solution is disadvantageous in terms of production technology, in particular because the double lever to be produced in precision form has a relatively complicated shape. There are also considerable disadvantages in use.
  • this known design requires a widened key channel, this key channel widening must continue in the region of the cross section of the double lever up to the mouth end of the key channel, and is on the side on which the control forces for the movable member are introduced. This reduces the security of the lock against scanning by means of known scanning tools inserted into the key channel.
  • This also has the disadvantage that the movable member can still be reached by a tool inserted into the remaining free key channel cross-section even when the key is fully inserted. So even if a key is inserted with a not adapted to the corresponding cylinder lock movable member, for. B. such a smaller dimensioning, this can be swung forward with such tools into a position that corresponds to the release position of the additional guard locking. The security value of the key is therefore very low.
  • the object of the invention is to design a generic design so that with simplified manufacture of the key and more convenient design of the same, the security value is considerably increased in that the movable member in the inserted end position of the key is not moved with scanning or burglary tools in the direction of the additional tumbler can be.
  • This object is achieved by the invention specified in the characterizing part of the main claim.
  • a cylinder lock with flat key has increased utility value, simplified manufacture and greater security.
  • a rolling body e.g. B. ball
  • the role property means that practically no increased friction occurs when inserting and removing the key. Since no parts can swing out over the broad side of the key, a key according to the invention is also easier to store. There is no risk of wear even over long periods of use. It is not necessary to dispense with part of the profile grooves in the key.
  • the fact that the rolling element is arranged in the area of a profile groove and has a larger diameter than the key in the area of this bearing point means that the material section provided in the key channel, which is known to positively enter the profile groove of the key, performs the control function.
  • the free transverse displacement of the rolling element in the key makes it possible to control the rolling element in its operative position in very short ways. In the inserted end position, the rolling element can no longer be moved transversely by any burglary or scanning tools by an additional stroke. The rolling body can therefore not be influenced in its stroke of action from the outside.
  • the undulating course of the key channel section made possible by the pure transverse displaceability of the rolling element, brings about a certain control scanning of the same already when the key is inserted.
  • the rolling body If the rolling body is too large in diameter, it cannot be pushed through this undulating section. Such a key is locked out before the rolling body could even come into the area of its operative position in opposition to the additional guard locking. If the rolling element is too small, the key would not be locked out in this regard; however, such a device would not control the additional tumbler as far as the release position and, because of its inaccessibility, could not be further controlled by the inserted amount by a scanning tool.
  • the waves shaped course optimizes the hiding position of the rolling element. There is then no straight insertion path for a scanning tool even on the key broadside opposite the profile groove, on which the rolling element is driven.
  • the rolling body lies fully on the end face of the projecting zone, so that in the longitudinal direction of the key and lock it is possible to work with larger tolerances which facilitate manufacture without compromising security.
  • the length of the projecting zones preferably corresponds to the diameter of the rolling body.
  • the smallness of the possible rolling elements, in particular balls, and their spatially narrow fastening possibility allow even several rolling elements to be provided on one key without enlarging the key.
  • the special solution for the wave-shaped course allows simple production in the milling process, so that instead of the key channel, which is otherwise only to be milled in a straight line, it only has to be milled in the wave shape in an outer partial area.
  • the control of the additional guard locking via a transmission lever also makes it possible to make do with small transverse displacements.
  • the special design, storage and mode of operation of the translation lever in this regard are structurally advantageous, particularly with regard to compliance with sufficient precision.
  • a ball it would also be possible, for. B. a cylindrical rolling body z. B. with crowned end faces.
  • the formation of the undulating course of the key channel section by means of corresponding pins arranged in a fixed manner in the cylinder core is not only advantageous in terms of production technology, but also brings about the possibility of considerable simple variation in the respective assembly of the cylinder lock and, above all, allows the undulating course at any height of the key channel can be manufactured.
  • the cylinder lock has a profiled lock cylinder housing 1.
  • a cylinder core 3 is rotatably mounted in a bore 2.
  • the latter is in a rotationally fixed connection with a lock bit 4 having a lock bit 4.
  • Lock cylinder housing 1 and cylinder core 3 have bores 6, 7 which are aligned with one another and which receive the tumbler pins 8. These are composed of the core pins 8 ′ and the housing pins 8 ′′. The latter are acted upon by a compression spring 9 in the direction of the cylinder core 3.
  • a key channel 10 In the axial longitudinal direction of the cylinder core 3 there extends a key channel 10, the channel side walls 11, 12 of which generate a cross-sectional profile of the key channel 10 by means of projecting ribs.
  • That of the key 13 is adapted to the cross-sectional profile of the key channel 10. This is composed of the key handle 14 and the key shaft 15. One narrow edge of the key shank 15 is equipped with key notches 16 of different depths which are arranged one behind the other and which are locked with the tumbler pins 8 cooperate and arrange them with the key inserted so that the parting line between the core pins 8 'and housing pins 8 "lies at the level of the core twist joint F of the cylinder core 3, see FIG. 5.
  • bearing bores 18 for receiving balls 19 extend transversely to this in the region of the upper longitudinal profile groove 17.
  • the bearing bores 18 are open to both broad sides S and S 1 of the key. Falling out of the balls 19, the diameter of which is smaller than the thickness of the key, is prevented by the fact that the bearing bores 18 end close in front of the broad side S 1 of the key, while on the other broad side S the bearing bores 18 are slightly closed. However, the balls can be moved.
  • the rib of the channel side wall 11 lying at the level of the longitudinal profile groove 17 of the flat key 13 bears the reference number 20.
  • this forms a wave-shaped course in such a way that an indentation E is opposite to a projecting zone Z.
  • the width of this undulating section is adapted to the diameter of the balls 19, while the length of the projecting zones Z corresponds approximately to the diameter of the balls 19.
  • a transmission lever 22 protrudes in the region of each indentation E of the channel side wall 12.
  • the latter is accommodated in a transverse slot 35 of the cylinder core 3 and is designed in the form of a circular segment such that its curvature 23 lies in the region of the rotary joint F of the cylinder core.
  • a wire 25 running in the longitudinal direction of the core and embedded in a shell-side groove 24 of the cylinder core 3 is used, which crosses a recess 26 of the translation lever 22 which is larger in cross section and open towards the core rotary joint F.
  • the other end 27 of the transmission lever 22 engages in a groove 28 of an additional tumbler 29.
  • the latter leads in a radially oriented bore 30 standing perpendicular to the key channel 10 and is loaded in the outward direction by a compression spring 31.
  • the aforementioned groove 28 has a beveled groove base 32, on which the end 27 of the transmission lever 22 is supported such that the outer section of the tumbler 29, which extends beyond this end 27, projects into a recess 33 in the lock cylinder housing 1.
  • both the tumbler pins 8 and the additional tumblers 29 represent a rotation lock.
  • the key notches 16, on the one hand arrange the tumbler pins 8 accordingly.
  • the balls 19 provided in a straight line one behind the other pass through the area of the key channel with the undulating course.
  • the balls 19 are pressed in the outward direction by the projecting zones Z of the one key channel wall 11 entering the profile longitudinal groove 17 of the flat key 13, so that they then protrude beyond the adjacent key broadside S. They act on the transmission levers 22, which move from the position according to FIG. 4 into the position according to FIG. 5.
  • the tumblers are moved into the unlocked position by the ends 27 of the transmission levers 22 facing the tumblers 29, whereby they come out of the area of the recesses 33 on the lock cylinder housing side.
  • the cylinder core 3 is then rotatable.
  • the compression springs 31 bring the tumblers 29 and also the transmission lever 22 into their starting position according to FIG. 4.
  • the key 13 cannot be inserted into a cylinder lock, the key channel of which does not have the corresponding undulating profile in the region of the longitudinal groove of the profile. If, on the other hand, a key equipped without balls 19 is inserted, which indeed arranges the tumbler pins 8, the additional tumblers are not controlled.
  • the recesses 33 of the lock cylinder housing are otherwise closed by fillers 34.
  • tumblers 29 could also be provided on opposite sides of the cylinder core in a staggered arrangement.
  • the bearing bores 18 for receiving the balls 19 are located at the end of the key 35 adjacent to the key notches.
  • the arrangement is such that when the key 35 is inserted, as shown in FIG. 6, the Balls 19 lie on the horizontal longitudinal center plane of the cylinder core 3.
  • the rib 20 'of the corresponding channel side wall partially projects into the longitudinal profile groove 17' of the key 25.
  • the rib 20 ' is surmounted by pins 36 arranged one behind the other in the insertion direction and non-rotatable, the inner ends 36' of which projecting zones are flattened on both sides. These ends 36 'enter the profile longitudinal groove 17' of the key 35 in a form-fitting manner.
  • pins 36 there are further pins 37, which are however arranged offset to the pins 36 and with their free ends 37 'dip into the key channel 10'.
  • the distance between the ends 37 'and the opposite surface of the rib 20' corresponds to the diameter of the balls 19, so that larger balls cannot pass through the key channel 10 '.
  • the pins 36, 37 thus also form a wave-shaped key channel section.
  • Additional tumblers 38 are accommodated in alignment with the pins 36. The same are provided with a stepped shaft 38 'projecting into the key channel 10'. The insertion movement of the tumblers 38 is limited by a shoulder 39 on the housing side. In the inward direction, the additional tumblers 38 are pressed by tumbler pins 40 on the housing side, which are in turn housed in closed radial bores 41 of the lock cylinder housing 1 '. The tumbler pins 40 are pot-shaped and each hold a compression spring 42 in their interior.
  • the balls 19 pass through the wave-shaped course of the key channel section formed by the pins 36, 37 and act on the additional tumblers 38 in the outward direction against spring loading, so that after the key has been fully inserted, the joint between the additional tumblers 38 and the tumbler pins 40 lies in the core twist joint. Since the other tumblers 8 are then also arranged, the lock cylinder core can be rotated by means of the key 35. Otherwise, the roller bodies 19 rest on the end face of the pins 36 in the inserted end position.
  • FIGS. 8 to 10 is such a cylinder lock in which the key 43 arranges tumbler pins 8 with recesses 44 arranged on its broad sides.
  • pins 45 and 46 which are fixed in the cylinder core, extend.
  • the inner ends 45 'of the pins 45 also protrude into the key channel 46 such that the distance between the opposite channel side wall 47 and the inner end 45 'corresponds to the diameter of the roller body 19, which is embedded in the key shaft of the key 45 and is designed as a ball.
  • the rolling body 19 is in a bearing bore 49 which extends in the material of the key shaft between two opposing longitudinal grooves 50 of the key 43. The latter can thus be used as a reversible key.
  • the rolling body 19 is freely displaceable such that it can protrude beyond the base of the respective longitudinal profile groove 50.
  • This pin 46 In opposition to the pins 45 there is between them the pin 46, which projects with its free end 46 'so far into the key channel 10 "that the dimension between the inner end 46' and the opposite channel side wall 51 corresponds to the diameter of the rolling element 19 , as illustrated by dash-dotted lines in Fig. 10.
  • This pin 46 is designed in the form of a mushroom pin such that the mushroom head 46 "lies in a blind bore 52 of the cylinder core and is supported on the inner wall of the cylinder core bore 2 'of the housing 1".
  • the blind bore 52 is dimensioned so that the inner end 46 'projects beyond the channel side wall 47 facing it by a certain amount.
  • the tumbler 53 lying behind the mushroom pin 46 in the direction of insertion is also designed in the form of a mushroom pin.
  • Their mushroom head 53 'lies in a blind bore 54 of the cylinder core and is acted upon by an undriven housing pin 55.
  • the housing pin 55 is equipped with a radially projecting tongue 56 which is guided in a groove 57 extending from the housing bore for the tumbler pin 55.
  • a spring-loaded housing pin 58 is supported on the tongue 56. As a result, the housing pin 55 is pressed into the blind bore 54 and shifts the tumbler 53 in such a way that it projects into the key channel 10 ′′.
  • the tumbler 53 is then shifted so far by the roller body 19 that the joint between the tumbler 53 and the housing pin 55 lies on the core twist joint D.
  • the same tumbler 53 is used. Furthermore, this tumbler 53 is preceded by a mushroom pin 46 on the same side of the key channel 10 ".
  • the channel wall 51 'opposite the inner end 46' is provided with an indentation 59, the distance between the indentation 59 and the end 46 'of the mushroom-shaped pin 46 corresponds to the diameter of the roller body 19.
  • the indentation 59 forms, in connection with the pin 46, an undulating path which is adapted to the diameter of the roller body 19.
  • the variants of the key 60 shown in FIGS. 12 and 13 are those which likewise classify the tumbler pins with their key broad sides.
  • the bearing bore 61 is located in a bush 62, which is slightly closed on both sides and is pressed into an opening in the central region of the key shaft.
  • the profile longitudinal grooves 63 extend on both sides of the sleeve 62 in such a way that the end faces 62 'of the sleeve 62 are flush with the base of the profile longitudinal groove. Therefore, as can be seen in FIG. 12, the rolling body 19 can be shifted from one end position drawn with full lines to the other end position indicated by dash-dotted lines. This then takes place in turn through the pins or protrusions of the key channel dipping into the profile longitudinal grooves 63.
  • FIGS. 14 and 15 bear the reference numerals of the embodiment relating to FIGS. 8 to 10.
  • a control pin 66 In alignment with the additional tumbler 53, which is also mushroom-shaped, extends in a stepped bore 64 a control pin 66, which is acted upon by a compression spring 65 and forms the projecting zone.
  • the compression spring 65 in turn is supported on a bore 64 which closes the bore outside of the core rotary joint F adapted plug 67.
  • the control pin 66 is provided with a collar 68 facing the compression spring 65, which is supported on the step 69 of the bore 64. Therefore, the free end 66 ′ of the control pin 66 can only protrude into the key channel 10 ′′ by a certain amount.
  • the height of the key channel 10 "in the area of the straight passage path for the ball 19 corresponds to the diameter thereof.
  • the mushroom-shaped tumbler 53 is guided so that the mushroom head 53 ' the immersion of the tumbler 53 in the key channel 10 "is prevented.
  • the ball 19 immersed in a longitudinal groove 50 of the key passes through the dimensionally adapted passage path and acts on the control pin 66 just before reaching the end insertion position. This moves against the force of the compression spring 65.
  • the control pin 66 is aligned with the ball 19 or with its bearing bore 49, so that the control pin can press the ball 19 in the direction of the tumbler 53. Since the compression spring 70 loading the housing pin 55 is weaker than that Spring acting on control pin 66, the tumbler 53 is displaced via the ball 19 and control pin 66 so that the joint between the tumbler 53 and the housing pin 55 lies on the core rotary joint F. Thereby, the control pin 66 also serves to close the bearing bore 49, which is unauthorized manipulation prevented on the tumbler 53 from the outside.
