Definitions

  • the invention relates to a device for adjusting the locking lever of a door lock from an open to a locking position and vice versa, the door lock in the locked position not being able to be opened with the outer door handle, but with the inner door handle, containing a remote-controlled control element and one by hand door knob to be actuated, the actuating element being coupled to the locking lever via a first actuating rod and the door knob being coupled via a second actuating rod.
  • central locking systems In today's motor vehicles, central locking systems have two locks installed at different points, mostly pneumatically operating, one of which is used to actuate the door lock and the other to provide additional theft protection. This arrangement requires a separate pressure medium line and corresponding pressure control devices at different points for each control element. Such a central locking system is complex and prone to failure.
  • the invention has for its object to provide a central locking system of the type mentioned so that with simple means when locking a vehicle first locked and then theft-proof and when opened the other way around theft-unlocked and then unlocked.
  • a mechanical coupling is additionally provided which can be moved by a door key and by means of which the locking lever can be pivoted into the open position independently of the actuating element.
  • a two-part actuating rod can also be provided, the parts of which can be displaced relative to one another against the restoring force of a spring in the actuating direction, the first part being connected both to the actuating element and to the mechanical coupling and having the actuating ramp and the second part is connected to the locking lever.
  • the parts each grip with an angled section over the other part, that the spring is designed as a compression spring and is arranged between the angled sections and that a stop in the form of a collar is provided on each part by which the displacement of the two parts is limited relative to each other.
  • Fig. 1 shows schematically a pneumatically operating actuator 1, which has a housing 2 with a pressure medium connection 3.
  • a working chamber 5 defined by a membrane 4 is formed in the housing 2.
  • a first actuating rod 6 is attached, which is hinged at its other end to a locking lever 7.
  • the actuating rod 6 runs twice bent, the bent region forming an inclined operating ramp 8 against which a locking pin 9 rests with one end.
  • the locking pin 9 is biased by a spring 10 towards the actuating rod 6.
  • the drawing also shows a door knob 11 which is connected to a free end of the locking lever 7 via a second actuating rod 12.
  • This actuating rod 12 has a locking receptacle 13 above the securing pin 9.
  • the actuating rod 6 is first shifted downward only as far as seen in the drawing until the actuating ramp 8 is just above the locking pin 9.
  • the locking lever 7 pivots in the locking position shown in dash-dotted lines.
  • the second actuating rod 12 also moves downward, the latching receptacle 13 remaining above the locking pin 9. If the central locking system is to be secured against theft, then the working chamber 5 of the actuating element 1 must be subjected to higher pressure.
  • the membrane 4 then moves with the entrainment of the parts 6, 7, 12 further downward, so that the actuating ramp 8 can move the locking pin 9 against the restoring force of the spring 10 to the left into the latching receptacle 13.
  • the actuating rod 6 can be formed in two parts. 2 shows an actuating rod 6 consisting of two rod parts 14, 15, angled sections 16, 17 extending over the other rod part in each case being provided. A spring 18 is supported against the underside of section 16 of the lower rod part 15 and against the upper side of section 17 of the upper rod part 14. In the position shown, the two rod parts 14 and 15 rest on a collar 19 above section 16 and a collar 20 below section 17.

Claims (4)

  1. Dispositif pour déplacer le levier de verrouillage (7) d'une serrure de porte d'une position d'ouverture à une position de verrouillage, et inversement, dispositif dans lequel, dans la position de verrouillage, la serrure de porte ne peut pas être ouverte par la poignée extérieure de la porte, mais peut toutefois l'être par la poignée intérieure de la porte, dispositif comprenant un élément de réglage (1) manoeuvrable à distance et un bouton de porte (11) devant être actionné à la main, l'élément de réglage (1) et le bouton de porte (11) étant accouplés, au levier de verrouillage (7), respectivement par l'intermédiaire d'une première tige d'actionnement (6) et d'une seconde tige d'actionnement (12), caractérisé par le fait
    - que le levier de verrouillage (7) peut être déplacé dans la direction de fermeture, au-delà de la position de fermeture, jusqu'à une position de protection antivol dans laquelle la serrure de porte peut être ouverte exclusivement par la clé de porte,
    - qu'il est prévu un loquet d'arrêt (9), agencé avec faculté de coulissement perpendiculairement à la direction de mouvement des tiges d'actionnement (6, 12),
    - que la première tige d'actionnement (6) présente une rampe d'actionnement (8), et la seconde tige d'actionnement (12) présente un logement d'encrantage (13), et
    - que le loquet d'arrêt (9) est engagé dans le logement d'encrantage (13) au moyen de la rampe d'actionnement (8), en s'opposant à la force de rappel d'un ressort (10), lorsque le levier de verrouillage (7) est déplacé à la position de protection antivol.
  2. Dispositif selon la revendication 1, caractérisé par le fait qu'il est additionnellement prévu un accouplement mécanique (22) auquel un mouvement peut être imprimé par une clé de porte (21), et au moyen duquel le levier de verrouillage (7) peut être animé d'un pivotement jusqu'à la position d'ouverture, indépendamment de l'élément de réglage (1).
  3. Dispositif selon la revendication 2, caractérisé par le fait qu'il est prévu, à la place de la tige d'actionnement (6), une tige d'actionnement en deux parties dont les parties (14, 15) peuvent être animées de coulissements relatifs dans la direction d'actionnement, en s'opposant à la force de rappel d'un ressort (18), la première partie (14) étant reliée tant à l'élément de réglage (1) qu'à l'accouplement mécanique (22), et étant munie de la rampe d'actionnement (8), et la seconde partie (15) étant reliée au levier de verrouillage (7).
  4. Dispositif selon la revendication 3, caractérisé par le fait que les parties (14, 15) viennent coiffer l'autre partie considérée par une région coudée (16, 17) ; par le fait que le ressort (18) est réalisé sous la forme d'un ressort de pression, et est interposé entre les régions coudées (16, 17) ; et par le fait qu'il est prévu, sur chaque partie (14, 15), une butée qui revêt la forme d'un collet (19, 20) ayant pour effet de limiter le coulissement relatif des deux parties (14, 15).
