Definitions

  • the invention is directed to a short circuit device of the type specified in the preamble of claim 1.
  • a central locking device is used, which will be referred to as "ZV device” in the following.
  • This ZV device has drives which act on a ZV lever in the individual locking devices and between them
  • an eccentric lever connected to the ZV lever should move into corresponding swivel positions, namely either into a securing position where associated lock members are ineffective, or into an unlocking position in which the lock members are set effectively.
  • the locking device has a lock cylinder with a key-operated cylinder core, which is connected to a driver in a positive and / or non-positive manner.
  • This driver is arranged coaxially to the eccentric lever already mentioned.
  • a pulse spring is provided, which automatically transfers the cylinder core to a zero position after a key operation, which lies between the locking and unlocking position. In this zero position, the key can be inserted and removed in the cylinder core.
  • the cylinder core can be turned further by the key into a safe position lying beyond the securing position, in which the eccentric lever is blocked. In the safe position, the key can also be inserted and removed in the cylinder core.
  • the eccentric lever is rotatably connected to the ZV lever.
  • These two levers can always be pivoted synchronously. This leads to malfunctions in the safe position of the cylinder core when the pair of levers is in its securing position, but, triggered by a control command coming from outside the device, the ZV device endeavors to transfer the ZV lever to its unlocking position. This leads to jams in the interior of the locking cylinder, which preclude or at least impair insertion of the key into the cylinder core. Such deadlocks occur e.g. between the tumblers to be controlled by the key and the locking channels assigned to them in the locking cylinder.
  • the invention has for its object to develop a reliable closure device of the type mentioned in the preamble of claim 1, in which the aforementioned operational problems no longer occur and which is characterized by a high level of operating convenience.
  • This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special significance.
  • a coupling means is arranged between the ZV lever on the one hand and the eccentric lever on the other hand. The effect of this is that these two levers are connected to one another in a rotationally fixed manner when the key is turned in the normal angular range between the securing position, via the neutral position and up to the unlocking position. If, however, the safe position is present, the two levers are uncoupled from the invention.
  • a coupling member is arranged between the cylinder core and the eccentric lever, which couples the cylinder core to the eccentric lever when, starting from the safe position, a key rotation takes place and if the ZV lever has previously been brought into its unlocking position. In this case a small turn of the key is sufficient; the cylinder core only needs to be transferred from the safe position to the zero position in order to bring the eccentric lever, which was previously in the secured position, into its unlocked position. This small angle of rotation is very user-friendly and makes it easier to operate the locking device.
  • Fig. 1 is an end view of the device according to the invention, in
  • FIG. 3 shows a cross section through the device shown in FIG. 2 along the section line III - III, 4a + 4b a cross section through the device of FIG. 2 along the section line IV - IV in two different positions, the cylinder core being highlighted by point hatching,
  • 5a + 5b are partial views of a cross section of the device according to the invention along the section line V - V of FIG. 2 when the locking cylinder is in its normal position but an associated eccentric lever assumes a secured or an unlocked position with respect to lock members,
  • 6a + 6b further partial views of a cross section through the device shown in FIG. 2 along the section line VI - VI there when the components are in the positions of FIGS. 5a and 5b and
  • 6c + 6d show the same cross sections as in FIGS. 6a and 6b when the locking cylinder or the components are in the positions of FIGS. 5c or 5d.
  • the closure device shown in FIGS. 1 and 2 is located at the rear of a vehicle in order to perform closing functions with respect to a tailgate.
  • the locking device includes a locking cylinder 10 which can best be seen from FIG. 2 and which consists of a cylinder core divided into two sections 11, 12.
  • the cylinder core 1 1, 12 is mounted in a fixedly positioned housing 13 and can be rotated by means of a key (not shown in more detail).
  • the cylinder core consists of an outer section 12, which has a protective cap 14 at the end is provided and has a key channel 15, which can be seen best from FIG. 1, for receiving the key.
  • the front end of the outer section 12 of the cylinder core, with its protective flap 14, projects outward from the body panel indicated by dash-dotted lines in FIG. 2.
  • the key channel 15 is accessible there.
  • Arranged in this outer section 12 of the cylinder core are the tumblers 16 which can be actuated by the key, the position of which is indicated by dash-dotted lines in FIG. 2.
  • the other section 11 of the cylinder core is connected in a rotationally fixed manner to this outer section 12.
  • This section 11 points into the interior of the vehicle, which is why it should be called the “inner section”.
  • the inner section 11 carries various coaxially arranged components 20, 30, 40. Between the two sections 11, 12 of the cylinder core, one cannot be closer If a torque is exerted on the outer section 12 which is below a certain limit value, there is a non-rotatable connection between the two core sections 11, 12.
  • the inner section 11 therefore rotates synchronously by turning the outer section 12 by key If the intrusion tools or the like exert a torque exceeding this limit value on the outer section, the overload clutch uncouples the inner section 11 from the outer section 12 of the cylinder core 1 and the seat there ends components 20, 30, 40 is not transmitted.
  • a driver 20 which is rotatably mounted on the cylinder core 11 and has both an axial nose 21 and a radial nose 22.
  • a stationary housing lug 75 In addition to the axial driving lug 21 there is also a stationary housing lug 75.
  • These lugs 21, 75 lie opposite the cut in FIG. 3 in an offset axial plane and are enclosed by the two legs 26, 27 of a pulse spring 25 which is placed around the cylinder core 11. This pulse spring 25 holds the cylinder core in the zero position illustrated by the vertical line 50.
  • the Cylinder core 11 can either be pivoted into the rotational position identified by line 51 or by line 51 'of FIG. 1.
  • the associated rotation angles marked 53 and 53 'in FIG. 1 are the same and may each be 55 °.
  • the housing 13 is provided with a window 29 which has end stops 28, 28' for the driving lug 22.
  • FIGS. 5a and 5b The latter can be seen from FIGS. 5a and 5b.
  • the driving finger 23 assumes the same position, although in FIG. 5a there has been a rotation up to position 51 of FIG. 1 and in FIG. 5b a counter-rotation up to position 51 'of the cylinder core 11.
  • 5a and 24 'in the case of FIG. 5b cooperated with corresponding counter shoulders 34 and 34' of an eccentric lever 30, which is another component of this device.
  • the eccentric lever 30 is rotatably arranged on the cylinder core 11 with a bearing piece 33.

  • the lock member 45 is a slide which can be displaced on a guide rod 35 from FIG.
  • FIG. 6a Another component of the opening device is a so-called ZV lever 40 according to FIG. 6a, which in turn is rotatably arranged with a bearing piece 43 with the interposition of the already mentioned bearing piece 33 by the eccentric lever 30 on the cylinder core 11.
  • the ZV lever 40 interacts with a drive of the central locking device mentioned above. This drive engages via a rod on a bearing eye 42 of the ZV lever 40.
  • the ZV lever 40 can either from this drive of the central locking device or, which will be explained in more detail, by the mentioned counter-rotation 18 'of the key from the position shown in Fig. 6a, drawn in solid lines in Fig. 1 and by the auxiliary line 41 1, which can be seen in FIG. 6b and is designated by the auxiliary line 41 '.
  • the ZV lever 40 is seated with its bearing piece 43 at the inner end of the cylinder core 11, where it is axially fixed by a locking ring 19 or the like. 2 and 6a, the two levers 30, 40 are normally connected in a rotationally fixed manner by a coupling means 55.
  • this coupling means 55 consists of a spring-loaded, axially displaceable pin which is longitudinally displaceable in a radial guide 44 by the ZV lever 40.
  • the pin 55 in the axial direction of the locking cylinder 11, can be divided into two pieces 56, 57, which have different lengths and from reasons evident below can be referred to as coupling piece 56 and control piece 57.
  • These pieces 56, 57 have the profile shape shown in FIG. 6a.
  • the bearing pieces 43 and 33 of the two levers 30, 40 have radial openings 36, 46 which are penetrated by the pin 55.

  • the radial opening 36 in the bearing piece 33 is stepped in its width and has a different clear width with respect to the two pin pieces 56, 57.
  • the radial opening 36 is narrow in the area of the coupling piece 56, which is why in the cases shown in FIGS. 6a and 6b there is a rotational entrainment between the two levers 30, 40.

Abstract

L'invention concerne un dispositif de fermeture à serrure comportant un cylindre de fermeture (10) manoeuvré par clé et qui agit sur des éléments de serrure par l'intermédiaire d'un levier à excentrique (30) lorsqu'il se trouve dans une position de déverrouillage et qu'il est actionné. Un levier de verrouillage centralisé (40), pouvant être commandé à partir d'un dispositif de verrouillage centralisé, est placé coaxialement au levier à excentrique (30). En cas de liaison de rotation entre le levier de verrouillage centralisé (40) et le levier à excentrique (30), on peut amener ces deux leviers dans une position de verrouillage dans laquelle les éléments de serrure sont désactivés. On peut poursuivre la rotation du noyau de cylindre (11) au moyen de la clé jusqu'à une position de sécurité dans laquelle le levier à excentrique (30) est bloqué et dans laquelle l'insertion et l'extraction de la clé dans le noyau de cylindre (11) sont possibles. L'invention vise à atteindre un confort d'utilisation élevé et à exclure des dysfonctionnements. A cet effet, on place entre le levier de verrouillage centralisé (40) et le levier à excentrique (30) un organe d'accouplement (55) qui relie certes les deux leviers (30 et 40) de sorte qu'ils sont solidaires en rotation en position de verrouillage et de déverrouillage, mais les découple en position de sécurité. On place en outre, entre le noyau de cylindre (11) et le levier à excentrique (30), un élément d'accouplement qui ramène le levier à excentrique lors de la rotation inverse du noyau de cylindre de la position de sécurité dans la position neutre.
