Definitions

  • the present invention relates to a vehicle door lock.
  • Locks comprising a fork and latch closing mechanism; an external opening control lever connected to the outside door handle; a safety control lever for enabling or disabling opening of the door from the outside; and an internal opening control lever connected to the inside door handle.
  • the safety control lever of such locks is normally connected to a safety knob inside the passenger compartment and movable between a depressed or recessed position and a raised or visible position respectively corresponding to engagement and release of the safety mechanism.
  • the safety knob therefore also provides for indicating the state of the lock (safety mechanism engaged or released).
  • the internal opening control lever of known locks normally presents a cam surface cooperating with a corresponding surface on the safety control lever for moving this from the engaged to the released position during a first portion of the travel of the inside handle, and so moving the safety knob from the depressed to the raised position.
  • the internal opening control lever is brought into contact with the latch which, when moved, releases the fork to open the lock.
  • GB-A-2 259 734 discloses a vehicle door latch system in which both the safety control lever and the opening control lever are actuated by the inside handle through a rod linked to such levers by a lost motion mechanism.
  • the complications involved in such known solutions fail to provide for entirely eliminating the above drawbacks.
  • a vehicle door lock comprising a fork and latch closing mechanism; an external opening control lever connected to the outside door handle; a safety control lever movable between a first stable position preventing opening from the outside, and a second stable position enabling opening from the outside; and an internal opening control lever connected to the inside door handle and traveling between a first idle position and a second position wherein it interacts with a pin of said latch to open the lock; characterized in that it comprises articulated connecting means between said safety control lever and said internal opening control lever, for moving said safety control lever between said first and second stable positions when the internal opening control lever is moved from the idle position to a third intermediate position of its travel, and vice versa.
  • number 1 indicates a perfected lock for a vehicle door (not shown).
  • Lock 1 comprises a structure 2 fittable to the vehicle door and supporting a number of movable elements as described below.
  • lock 1 comprises a known fork and latch type closing mechanism 3 cooperating with a striker element 4 on the door post (not shown) when the door is closed.
  • Lock 1 also comprises an external opening control lever 5 connected to the outside door handle; an internal opening control lever 6 connected to the inside door handle 7; and a safety control lever 8.
  • Lever 5 is hinged to structure 2 by a pin (not shown), and is movable between an idle position and an operating position (not shown) wherein it releases the latch of closing mechanism 3.
  • Lever 6 is hinged to structure 2 by a pin 13, and is movable between a first idle position a maintained stably by a known spring 14 associated with lever 6, and a second position b rotated clockwise in relation to position a ( Figure 4) and wherein it interacts, by means of an appendix 25, with a latch pin 15 for releasing the latch.
  • Lever 6 is connected to handle 7 by a rigid rod 16, so that handle 7 is movable between a stable idle position A corresponding to position a of lever 6, and an unstable opening position B corresponding to position b of lever 6.
  • Safety control lever 8 is hinged to structure 2 by a pin 17, and is movable in known manner between a first engaged position (Figure 1) wherein lever 5 is made ineffective by conventional linkages (not described in detail), and a second position ( Figures 3 and 4) rotated clockwise in relation to the first position and enabling lock 1 to be opened externally by means of lever 5.
  • the first and second positions of the lever are defined by striker elements (not shown) fitted to supporting structure 2 and with which lever 8 cooperates, and are made stable by a known bistable spring 24 securing lever 8 to structure 2.
  • lever 6 comprises a first bottom arm 18 secured to rod 16; and a second substantially lateral arm 19 secured to one arm 20 of lever 8 by a connecting rod 21 pivoting on levers 6 and 8 by means of respective end pins 22, 23 ( Figure 2).
  • Pin 22 on lever 6 engages a longitudinal slot 28 formed in connecting rod 21 for the purpose described later on.
  • lock 1 Operation of lock 1 will now be described as of the closed condition, with the safety mechanism engaged, shown in Figure 1 wherein handle 7 and lever 6 are set to respective positions A , a , and lever 8 to said first position.
  • Handle 7 also provides for indicating the state of the lock, by assuming two stable positions A and C corresponding respectively to engagement and release of the safety mechanism.
  • the dotted line portion of Figure 4 shows an alternative embodiment of of lock 1 wherein the traditional safety knob is retained if requested by the vehicle manufacturer.
  • the safety knob, indicated 26, is connected to lever 8, conveniently provided for the purpose with a longer arm 20', by means of a tie 27, and performs the usual function of engaging or releasing the safety mechanism when set to the depressed or raised position corresponding to the first and second position of safety control lever 8.
