Definitions

  • the present invention relates to an ignition lock with blocking mechanism for motor vehicles, in particular motor vehicles which are equipped with automatic gearboxes.
  • the construction of the ignition lock and the blocking mechanism on vehicles with automatic gearboxes means that the key can only be taken out if the gear change lever is in the park position and also that the gear change lever cannot be moved out of the park position when the key is not in the ignition position, which results in increased safety.
  • the invention concerns an ignition lock with blocking mechanism for motor vehicles, in particular for- motor vehicles with automatic gearboxes to prevent the ignition being switched off if the gear change lever is not in the park position
  • the ignition lock comprises an outer lock cylinder with a slot for an ignition key
  • the blocking mechanism comprises a sliding body which, via a mechanical connection element, can be caused to take up different positions depending on the position in the gear change gate or the like as well as cooperating means between said lock cylinder and said sliding body which means only allow positioning of the lock cylinder in the ignition switch-off position if the sliding body is located in a certain predetermined position, which position corresponds to the park position for vehicles with automatic gearboxes.
  • Such an ignition lock prevents therefore that the ignition can be switched off, if special conditions have not been ful illed, for example if the gear change lever is not in the park position in a vehicle equipped with an automatic gearbox.
  • the invention concerns a blocking arrangement f ⁇ rlgnition locks of the above mentioned type, which is characterized in that said means comprises a first member secured against rotation with respect to said lock cylinder, which member directly cooperates with part of said sliding body which conforms at least partly to this member, so that the ignition lock can only be put into the switch-off position if said sliding body is located in a certain predetermined position.
  • Such a construction provides a solution which, in comparison to known solutions, reduces the costs and at the same time increases the reliability, which primarily is due to the fact that the construction according to the invention eliminates the need for a movable element in comparison to the known solution which is evident from the closest state of the art, see DE-A-34 25 189.
  • a further object of the invention is to shape certain parts in such a way that they are able to be combined with ignition locks of differing constructions. In this way one should preferably be able to use the same sliding body, wire and associated connections for example on both the Volvo 940 and the Volvo 960 even though__the ignition locks in both these car types have large differences.
  • Fig. la shows a first embodiment of the blocking arrangement in section along the sliding body, in a blocking position.
  • Fig. lb shows the same section a in Fig. la but in a non-blocking position.
  • Fig. 2a shows a preferred embodiment of a blocking arrangement according to the invention in a blocking position.
  • Fig. 2b shows a non-blocking position,
  • Fig. 3 shows an ignition lock seen from within the vehicle interior
  • Fig 4 shows a first marked section in Fig. 3
  • Fig 4b is an enlargement of chosen parts from Fig. 4a, and Fig.5 shows a second marked section in Fig. 3, which section depicts a longitudinal cross- section through the blocking arrangement seen from above.
  • Fig. la there is shown a first embodiment of an ignition lock with a blocking mechanism according to the invention.
  • the Figure shows, in section, a lock cylinder 1 operable by means of a key (see fig. 3) , which lock cylinder cooperates with a sliding body 2.
  • the sliding body 2 is movable transversely with respect to the cylinder lock and is caused to be displaced by a wire 3.
  • body 2 is positioned in such a way that the lock cylinder 1 has been able to rotate to an angular position where the key can be taken- out of the ignition lock.
  • Fig. la the sliding: body 2 is positioned in such a way that the lock cylinder 1 has been able to rotate to an angular position where the key can be taken- out of the ignition lock.
  • the sliding body 2 has moved out of the above mentioned position due to which the lock cylinder 1 cannot rotate to an angular position where the key can be removed, i.e. to the position corresponding to the engine being switched off.
  • the sliding body 2 is cylindrical and has a plurality of rotationally-symmetrical recesses 4, 11, 12. The largest of these recesses is, in a given position, intended to cooperate with a cam 5 on the lock cylinder 1.
  • the lock cylinder 1 is rotatably arranged in a cylinder block 6 in relation to which a casing 7 for the sliding body 2 is fixed. In said housing 7 there is a recess 8 inside of which a spring has been arranged.
  • Said spring 9 has a pin ⁇ like front part 10 intended to cooperate with the tracks 11, 12 in the sliding body 2. Said spring 9 holds, under particular circumstances, the sliding body 2 in certain predetermined positions.
  • the sliding body 2 is positioned so that the lock cylinder 1 can rotate to the position which corresponds to switching off the ignition.
  • the second track 11 defines the position at the sliding body 2, where the gear change lever has moved out of the P-position.
  • the sliding body 2 is thus connected with the gear change lever (not-shown) by means of the wire 3.
  • fig. lb it is shown how the sliding body is positioned when the gear change lever is in the drive- position.
  • fig. lb shows how a wire-holding casing 13 is fixed, with the help of a nut 14, to the housing 7.
  • the wire casing 15 has then been fixed to the casing 13 by means of appropriate fastening means 16.
  • FIG. 2-5 there is - ' shown a preferred embodiment according to the invention.
  • this embodiment is shown in longitudinal cross-section.
  • FIG. 2a there is shown- ⁇ the position where the sliding body 2 is located so that the recess 4 cannot accommodate the cam 5 in the lock cylinder 1.
  • This cam-like part 5 consists not only of a radially outwardly extending part, but also of a flange-like part 17 which extends rearwardly in an axial direction, so that a ring-formed segment 17 is formed.
  • Fig. 2 shows further that the casing 13 for attachment of the wire casing 15 is of the "snap-in" fastening type.
  • This latter element is in turn connected, centrally and in a rotationally-fixed manner, by means of a male/female coupling " 20, with the inner end of the lock cylinder 1.
  • This latter mechanism 18, 19, 20 ensures that the lock cylinder 1 springs back after positioning in the ignition position.
  • Fig. 3 shows an ignition lock according to the invention seen from inside the passenger cabin. The figure shows the different markings which are found on such an ignition lock together with the slot 26 for the ignition key (not shown) . Further, Fig. 3 shows two section markings for Fig. 4 and 5.
  • Fig. 4a thus shows a cross-section through the centrally- extending axis of the lock cylinder, in a vertical direction.
  • Fig. 4b is a partial enlargement of the aforementioned section. This enlargement shows distinctly how the flange ⁇ like segment 17 of the lock cylinder 1 is shaped. Further it is clear that the sliding body has a rectangular cross- section. The figure shows a situation in which the sliding body is in a position which corresponds to switching-off the ignition.
  • Fig. 5 there is shown the sliding body 2 positioned in a non-blocking position, in section and seen from above.
  • the gear change selector is thus in the park position and the sliding body 2 is displaced inwardly into the housing 7 and bears against the cylinder block 6.
  • the cam 5 occupies a position in the recess 4 it is not possible to move the gear change lever out of the park position before the key is rotated backwards.
  • the wire 3 can be replaced by a chain, or similar flexible force-transmitting element or, by a specially chosen placing of the ignition lock, by a rod.
  • cross-sectional shapes of the sliding body other than circular and rectangular can be used.
  • Other modifications which are encompassed by the scope of the invention are for example that instead of an integrated cam element one can have a rotatably-fixed disc or the like on the lock cylinder.
