Definitions

  • the invention relates to a lock, in particular on a vehicle door, with the features specified in the preamble of claim 1.
  • Such a lock is to be assumed in DE 35 31 931 A1, in which a coupling element which is connected to the lock cylinder in a rotationally fixed manner should have a head part with a coupling tooth, which should engage in a tooth recess in the lock nut for rotational coupling of the coupling element with a rotatable lock nut of a locking device.
  • the coupling element can be divided or separated from the lock cylinder in the event of an attempted break-in by external force, whereby at least after removal of a remaining part of the coupling element, a foreign tool can be inserted into the tooth recess through an opening in the door, with which the lock nut can be locked can twist and thereby open the lock.
  • the invention has for its object to provide a lock with the features in the preamble of claim 1, which prevents unauthorized rotation of the lock nut in an unlocking or opening position of the lock in a violent separation of the coupling element or disconnection of the coupling element from the lock cylinder.
  • the locking body which is automatically adjusted into the locking position by the force of the spring, prevents an external tool or a part comparable to the coupling element from engaging through an opening in the door.
  • the securing body can be automatically fixed in the securing position by a locking device which, for example, has to be released from the inside during assembly of the lock, so that the coupling tooth can be inserted into the tooth recess.
  • the locking device of a lock shown in Fig. 1 is attached as a prefabricated module inside the door of a motor vehicle and contains a locking part, not shown in detail, which can be adjusted by turning a lock nut 1 in an unlocking position or in a locking position in which a transmission element is locked between an outer or inner handle and a pawl interacting with a catch or executes an idle stroke when the handle is actuated.
  • the lock cylinder 3 shown in FIG. 2 is also attached to the vehicle door, not shown, and can be rotated in the usual way by a key that can be inserted into a key opening 4 in the lock cylinder 3.
  • the locking cylinder 3 is connected in a rotationally fixed manner to a coupling element 5, which is limitedly adjustable in angle with respect to the axis of the locking cylinder 3.
  • the coupling element 5 has a head part 6, on which a plurality of coupling teeth 7 are formed which are uniformly distributed over the circumference and which can be inserted axially into the radial tooth recesses 8, 8 'shown in FIG. 1 in the lock nut 1, as a result of which the coupling element 5 is rotatably connected to the lock nut 1 is coupled.
  • the coupling element 5 is forcibly separated, for example from a tool guided through an opening in the vehicle door or separated from the locking cylinder 3, possibly after removal of a remaining part of the coupling element 5 or the Head part 6 from the lock nut 1 a foreign tool cannot engage in the tooth recesses 8, 8 'in the lock nut 1 and can turn the lock nut 1, the securing device shown in FIG. 3 is provided.
  • the securing device has a locking body 10 which is axially adjustable in an axial recess 9 of the lock nut 1 and which engages with webs 24, 24 'or teeth in longitudinal grooves 12, 12' in the lock nut 1, which protrude radially at uniform angular intervals in the circumferential direction and thereby rotatably and axially is adjustably connected to the lock nut 1.
  • the securing body 10 is axially loaded by a spring 11 against the head part 6 of the coupling element 5, which engages with its coupling teeth 7 in the tooth recesses 8, 8 'of the lock nut 1.
  • the longitudinal grooves 12, 12 ' are formed by corresponding extensions of the tooth recesses 8, 8'.
  • the securing body 10 has an axial extension 13, which is coupled in a rotationally fixed manner to a rotatable gearwheel 15, for example via a sliding block 14.
  • the projection 13 forms a locking head 16 which is provided with inclined surfaces 17, 17 ', against which radially adjustable locking elements 18, 18' each abut with a correspondingly inclined contact surface 19, 19 'or a contact edge.
  • the coupling teeth 7 are either removed from the tooth recesses 8, 8 'by the action of force or during the automatic axial displacement of the securing body 10 into a by the force of the spring 11 Secured position, in the figure to the right, moved out of the securing body 10 out of the tooth recesses 8, 8 '.
  • the locking elements 18, 18 ' are adjusted radially outward from the adjustment area of the securing body 10 in cooperation with their contact surfaces 19, 19' with the inclined surfaces 17, 17 'of the securing body 10 and at least fall in the Secure position in radial recesses 20, 20 'in the fuse body 10.
  • the securing body 10 is locked by the locking elements 18, 18 'and cannot be adjusted axially either outwards or inwards.
  • the outer end face 21 of the securing body 10 is approximately flush with the outer end face 22 of the lock nut 1.
  • a third-party tool guided through an opening in the vehicle door or a part comparable to the coupling element cannot therefore enter the tooth recesses 8, 8 'are inserted into the lock nut 1 to twist the lock nut 1 to unlock or unlock it without authorization or to open the lock.
  • the rotational coupling of the securing body 10 is released from the gear 15, since in the secured position the sliding block 14 no longer engages in the groove recess 23 formed in the gear 15, but is axially displaced out of the groove recess 23. Even if the lock nut could be rotated without permission in the secured position, the rotational movement of the securing body connected in a rotationally fixed manner to the lock nut cannot be transmitted to the gear wheel 15.
  • a new coupling element 5 can be inserted with its head part 6 into the axial recess 9 in the lock nut 1 or the coupling teeth 7 into the tooth recesses 8, 8 ', is on the locking device 2 shown in Fig. 2 an unrecognizable device is provided with which the locking elements 18, 18 'are to be displaced from the inside of the vehicle door out of the radial depressions 20, 20' in the securing body 10, so that in cooperation with the head part 6 of a coupling element 5 newly inserted into the recess 9, the securing body 10 can be adjusted axially into the normal position shown in FIG. 3.
  • the locking device for locking the securing body in its securing position can also be formed in another way.
  • a locking device cannot be provided, for example if the securing body is held sufficiently stable in the securing position under the force of the spring or self-locking and can therefore withstand the axial forces to be expected in the event of a break-in attempt with which a foreign tool or the like can be inserted into the tooth recesses the lock nut is to be inserted.
  • a pivotable locking element can also be provided. The rotary movement can also be transmitted directly or indirectly from the coupling element to, for example, a gearwheel.
  • a rotationally fixed coupling of the lock nut with the securing body or the securing body with a gear or driven gear can also be done in another way, for example via a driver or the like. Basically, it is sufficient if a single coupling tooth formed on the head part engages in a corresponding tooth recess. For safety reasons or a more even load, as in the exemplary embodiment, a plurality of coupling teeth or tooth recesses can be provided, which need not be arranged symmetrically.
