Definitions

  • This invention relates to a door latch and lock assembly particularly for use on the doors (including the tail gate and boot lid) of a motor vehicle.
  • Most known locks comprise a key cylinder which has a key slot accessible outside of the vehicle for receiving a key.
  • the inner end of the key cylinder is connected to a latch mechanism which actually holds the door shut by means of a link.
  • This link is often accessible to a thief, and by obtaining access to the link otherwise than through the lock, the thief can open the door.
  • a door latch and lock assembly for a motor housing as specified in claim 1.
  • the invention also provides a door latch and lock assembly for a motor vehicle as specified in claim 2.
  • the switch housing preferably encloses two microswitches which can be connected to an electronic control unit so that the action of turning the key is signalled to the control unit. This can then be used to activate or deactivate an alarm system or other electrical system.
  • the engagement between the cylinder and the rotatable member is preferably achieved by a non-round male member on one component engaging in a correspondingly shaped female socket on the other component.
  • the male member is on the cylinder and the female part is on the rotatable member.
  • the rotatable member may have two radial fingers which extend into the latch housing, on either side of a latch operating member, so that rotation of the key which rotates the rotatable member also results in contact between one or other of the fingers and the latch operating member, to operate the latch mechanism.
  • the lock unit may be secured to a vehicle door panel by inserting the barrel through a hole in the panel and then mounting a retaining clip on the barrel on the inside of the door panel.
  • the lock unit may be connected to the switch housing by passing the barrel through a hole in a wall of the housing and then mounting a retaining clip inside the housing, on the lock barrel.
  • the switch housing may be connected to the latch housing by riveting the two parts together, and the latch housing and switch housing may be pre-assembled and then mounted in a door as a single unit.
  • the invention is also directed to a motor vehicle door latch mechanism as specified in claim 10.
  • the exposed drive member is a non-round socket adapted to receive a correspondingly shaped projection on the end of a key cylinder.
  • FIG 1 shows a lock unit 10, a switch housing 12 and a latch housing 14.
  • the switch housing 12 and the latch housing 14 together make up a latch mechanism.
  • the lock unit 10 has a head 16 with an aperture in the form of a slot 18 for receiving a key.
  • the head 16 will normally be mounted on the outside of a vehicle door panel 20, as illustrated in Figure 2.
  • the unit 10 has a barrel 22, and a cylinder rotates within the barrel 22 and ends in a non-round male member projection in the form of a rotatable spigot 24. When the correct key is inserted in the slot 18 and rotated, then the spigot 24 turns relative to the barrel 22.
  • the switch housing 12 encloses a rotatable member 26, the shape of which is shown most clearly in Figure 3.
  • This member 26 has an exposed drive member in the form of two sockets 28 which receive the spigot 24, such that rotation of the cylinder with the spigots produces rotation of the rotatable member 26.
  • the member 26 has two fingers 28a which extend radially from the member and lie either side of a latch operating member 30 mounted within the latch housing 14.
  • the operating member 30 is connected to a latch arm or actual latch member 32 by a mechanism which is not illustrated in detail in the Figures, but which will be familiar to the skilled man.
  • the operating member 30 can be moved in the directions indicated by the double headed arrow 34, about an axis 36. Thus rotation of the correct key in the slot 18 will turn the rotatable member 26 which will turn the latch operating member 30 which will lock and unlock the latch mechanism.
  • the switch housing 12 On assembly, the switch housing 12 will be connected directly to the latch housing 14 so that neither the operating member 30 nor the rotatable member 26 are accessible.
  • the engagement between the spigots 24 and the sockets 28 will be wholly inside the housing 12, as indicated with reference to Figures 1 and 2.
  • Figure 1 it can be seen that the barrel 22 has two pairs of slots 38 and 40, and two retaining clips 42 and 44 are illustrated.
  • Figure 2 shows how the retaining clip 42 is fitted to secure the barrel 22 to the door panel 20, and how the clip 44 is fitted (inside the switch housing 12) to secure the barrel to the switch housing with the rotatable spigots 24 and the rotatable member 26 concealed within the switch housing.
  • Figure 3 also illustrates two microswitches 46 and 48 which are mounted on an end wall of the housing 12 and will be operated by respective ones of cam surfaces 50, 52 on the rotatable member 26. Therefore when the key is inserted and turned, one or other of the microswitches 46, 48 will be closed so that a corresponding signal is sent to an electronic control unit 54.
  • the assembly as described also allows for possible manufacturing tolerances, in that the fit between the spigots 24 and the sockets 28 can allow a degree of lost motion without adversely affecting the operation, and axial tolerances between the lock unit and the switch housing can be accommodated by allowing different depths of insertion of the spigots 24 into the sockets 28.
