Definitions

  • the invention relates to a device for locking and controlling the opening of a side door of a motor vehicle comprising, mounted on a lock plate, a locking lever capable of occupying two stable positions, one said to be locked and the another so-called unlocked, pivoting around a first articulation axis fixed to the plate, and a disengageable external opening control lever pivoting around a second articulation axis fixed to the plate: distinct and parallel to the first axis .
  • Patent FR-A-2,355,147 describes a lock plate on which is pivotally mounted a locking lever bearing on a latch release finger and which has a return to the square engaged in the notch of a lever of interior control.
  • the locking lever can be actuated in the locking / unlocking directions by an internal control lever mounted to pivot about an axis perpendicular to the axis of rotation of the locking lever.
  • This device does not avoid the deformation of the locking elements of the lock as a result of a forced opening command when the lock is locked. The breaking of the lock remains therefore possible.
  • Patent US-3,591,22O describes a lock for a side door of a motor vehicle in which the external control lever can be disengaged when the lock is locked.
  • an intermediate lever articulated around an axis carried by the locking lever has at its end a stop which makes the coupling between two opening control levers and which makes it possible to disengage one of these levers in the purpose of keeping the lock in a locked position after closing the door.
  • This lock cannot therefore be unlocked automatically following a closing movement of the door, which can be a nuisance when the keys of the lock remain inside the vehicle.
  • the object of the present invention is to take advantage of a lock plate of simplified design as described by patent FR-A-2,355,147 by adding means which allow the disengagement of the external control lever during a locking the lock and means which authorize the opening of the lock by action of the locking lever on the pin release finger.
  • the device according to the invention is essentially characterized in that the locking lever has a general U-shaped shape, the ends of the branches of which bear the first axis and, respectively, a third axis for the articulation of an intermediate lever with respect to to the locking lever and pivoting with the latter around the first axis, so that, if the locking lever occupies its first stable position, called unlocked, the third axis is superimposed on the second axis in order to allow the lever to rotate.
  • the intermediate lever escapes the control lever outside.
  • the device thus produced therefore makes it possible to automatically unlock, by simply slamming the door when it is closed, a door which would be inadvertently condemned before it is closed.
  • Figure 1 shows in plan, the entire device mounted on a support plate 1, itself fixed to the sheet metal 2 in the box of a side door of the vehicle, by means of screws passing through threads such as those shown in 3.
  • the locking lever 4 pivotally mounted around a first fixed axis 5, integral with the plate, has a general configuration in a deformed U, the articulation axis 5 being located approximately at the end of one of the branches 6 of the U, extended transversely by a rigid jaw comprising an upper spout 7 and a lower spout 8 exposed to the stress of a locking finger 9, moved vertically from the external barrel lock (not shown).
  • the space formed between the branches of the U forms a circular buttonhole 10, closed at the top by a return 11 to the square practiced in the extension of the end of the second branch 12 of the locking lever 4.
  • This last branch carries another axis, called third axis 13, for the articulation..of an intermediate opening lever 14, relative to the locking lever 4, and pivoting with the latter around the first axis 5, relative to the plate 1.
  • the first and third axes 5, 13 are shown in section in FIG. 4.
  • the intermediate lever 14 forms a small sector capable of debating in the buttonhole 10 of the locking lever 4 by partially covering it, the curvilinear edge 15 of the sector conforming to the circular shape of the buttonhole 10.
  • the two rectilinear sides 19, 20 of the intermediate lever sector come to tangent respectively, on the one hand, a stop 21 issuing perpendicularly from the external control lever 17 and, on the other hand, a finger 22 for triggering the bolt of the lock, the latter being able to debate around the theoretical axis 16 by passing through a curvilinear lumen 23 of the plate between the intermediate lever 14 and the underside of the bracket 11 of the locking lever 4.
  • the intermediate lever 14 is constantly biased against the stop 21 by means of a spring 24 hooked between said lever 14 and the locking lever.
  • the locking lever 4 can be held in one of its two stable positions, corresponding respectively to FIGS. 1 and 3, by means of a bistable spring 25 hooked between said lever 4 and the plate 1. For each of these positions, the movement of the locking lever is limited by an upper stop 26 of the plate 1.
  • the locking lever 4 can also be tilted equally into the appropriate position by the pivoting of an internal control lever 27.
  • the transmission of the movement takes place by the upper bracket 11 of the locking lever 4 penetrating into a notch 28 of the interior control lever 27, itself actuated from inside the vehicle by a movement transmission such as a rod 29 hooked on said lever 27.
  • a return spring 30 wound around the axis 5 of the locking lever biases the internal control lever 27 in the locked position of Figure 3 by resting, on the one hand, on the jaw 7 of the lever 4 and, on the other hand, in a second notch 31 of the internal control lever 27.
  • the device operates in the following manner: In FIG. 1, the locking lever 4 occupies its first stable position known as unlocking or engaged for which the articulation axes 16, 13 of the external control lever and of the intermediate lever are combined ( figure 4).
  • the external opening control lever 17 being at rest, its stop 21 is disposed opposite the intermediate opening lever 14 ( Figure 5).
  • the opening of the lock and therefore of the door corresponds to the passage from FIG. 1 to FIG. 2 in which the external control lever 17 has been maneuvered from bottom to top, causing it to rotate, by means of its stop 21 , the sector of the intermediate lever 14 and the trigger finger 22 of the bolt of the lock.
  • the movement is limited by the bottom of the curvilinear light 23 of the plate, the finger coming flush with the underside of the bracket 11 of the locking lever 4 which has remained fixed.
  • the spring 24 recalls the intermediate 14 and external control 17 levers towards their rest position in FIG. 1.
  • the locking of the lock results from the pivoting of the locking lever 4 towards its second stable position in FIG. 3, pivoting obtained either from the outside by the upward movement of the finger 9 of the barrel lock against the upper beak 7 of the lever ( Figure 1), either from the inside by the pressure exerted downwards by the interior control lever 27 on the bracket 11 of the locking lever.
  • the return of the locking lever 4 to the unlocked position of FIG. 1 can be obtained by the reverse actions of the previous ones with the finger 9 of the lock or of the internal control lever 27, according to the arrows in FIG. 3.
