Definitions

  • the present invention relates to a vehicle door lock assembly.
  • door is used in its widest sense as indicating any assembly consisting of a fixed body element, e.g. door post, defining an opening, and a movable element or wing for closing the opening, and as such applies equally to the side doors, boot lid or rear door.
  • Vehicle door lock assemblies normally comprise a lock fitted to the movable element or wing of the door, and a striker fitted to a fixed body element defining the door opening, or vice versa.
  • a lock assembly for a vehicle door comprising a fixed element defining a door opening, and a movable element for closing said opening; the lock assembly comprising:
  • number 1 indicates a lock assembly for a vehicle door comprising a fixed element 2, e.g. a post, defining a door opening 3, and a movable element 4, e.g. a door, for closing opening 3.
  • a fixed element 2 e.g. a post
  • a movable element 4 e.g. a door
  • Lock assembly 1 comprises a lock 5 housed in post 2 and presenting a rigidly fixed casing 6; and a striker 7 fixed to door 4, and cooperating with lock 5 and housed inside a seat 8 in casing 6 when the door is closed.
  • Lock 5 presents a conventional lock mechanism 9 comprising a fork 10 and a catch 11.
  • Fork 10 is hinged to casing 6 about a horizontal axis A, presents a concave seat 14 for striker 7, and is movable between a release position - wherein seat 14 faces the entrance opening 8a to seat 8 formed in casing 6, for receiving striker 7 - and a rotated lock position - wherein fork 10 surrounds and prevents striker 7 from being withdrawn from lock 5.
  • Fork 10 is pushed into the release position ( Figure 1) by a spring (not shown), and is held in the lock position by catch 11.
  • catch 11 is hinged to casing 6 about an axis B parallel to axis A, and is spring-loaded (not shown) towards fork 10 so that the end portion 15 of catch 11 engages a pawl 16 on the periphery of fork 10, for maintaining it in the lock position.
  • Striker 7 is substantially cylindrical, and is rigidly connected at opposite ends and by permanent deformation to a plate 18 for securing it to door 4, and to a supporting bracket 19 integral with plate 18 and forming with it a U-shaped supporting structure 21.
  • Plate 18 is fitted to the panel 22 of door 4 by means of a counterplate 23 on the opposite side of panel 22, and by means of a pair of screws 24 for gripping plate 18 and counterplate 23 on to panel 22. Screws 24 are fitted in radially slack manner through holes 24a in panel 22, to enable striker 7 to be adjusted in relation to lock 5 and so compensate for the manufacturing and assembly tolerances of the door elements.
  • Assembly 1 also comprises a manually operated device 25 for releasing lock 5, and which provides for transmitting the mechanical release action of a manually operated activating member (not shown) on door 4, e.g. a handle, to lock 5.
  • a manually operated activating member not shown
  • device 25 comprises an activating rod 26 housed in sliding manner inside a cavity 26a through striker 7, and movable axially between a withdrawn idle position (shown by the darker line in Figure 2) and an active position (shown by the fainter line in Figure 2) wherein its end 28 projects axially from striker 7 and, by means of a transmission mechanism 27 described below, provides for releasing catch 11 of lock 5 from fork 10.
  • Rod 26 is operated by a remote control element, e.g. a tie 29 connected to the door handle (not shown), and via a rocker arm lever 30 hinged centrally to a supporting bracket 31 integral with and bent 90° in relation to the counterplate, so as to rotate about an axis C perpendicular to the axis of rod 26.
  • Lever 30 is connected at opposite ends to tie 29 and to rod 26 which, for the purpose, presents a head 32 opposite end 28 and presenting a through slot 33 loosely housing a pin 34 on lever 30. As such, when tie 29 is pulled, lever 30 is rotated and pushes rod 26 into the active position.
  • Transmission mechanism 27 comprises a push rod 35 sliding inside a seat 35a formed in casing 6 and communicating with seat 8 along an axis D parallel to axes A and B and coincident with the axis of striker 7, and hence of rod 26, when door 4 is closed.
  • Mechanism 27 also comprises a square lever 36 hinged to casing 6 about an axis E perpendicular to axes A, B and D, and presenting an arm 37 resting on and operated by push rod 35, and an arm 38 cooperating upwards with a substantially radial projection 39 on catch 11, and which provides for rotating catch 11 in such a direction as to release it from fork 10.
  • Push rod 35 presents an intermediate annular projection 40 which cooperates with casing 6 to define the idle axial position of the push rod.
  • Assembly 1 operates as follows.
  • Lock 5 is locked in the normal way by firmly closing door 4, in which position ( Figure 2), rod 26 and push rod 35 are coaxial with each other.
  • position ( Figure 2), rod 26 and push rod 35 are coaxial with each other.
  • rod 26 moves from the idle position to the active position (shown by the fainter line in Figure 2);
  • push rod 35 transmits the thrust exerted by rod 26 to arm 37 of lever 36; and
  • lever 36 rotates clockwise (in Figure 2) so that arm 38 cooperates with and releases catch 11 from fork 10 which is thus swung into the release position by its return spring (not shown).
  • lock assembly 1 The advantages of lock assembly 1 according to the present invention will be clear from the forgoing description.
  • the release device may be controlled by means of a Bowden cable or any other suitable rigid or flexible transmission element; the transmission element may be connected directly to rod 26; lever 30 and transmission device 27 may be replaced by any other member or mechanism suitable for the purpose; and lock 5 may be fitted to the movable as opposed to the fixed door element.
