after mounting on a door.

  In Figures 1, 2A and 2B there is shown in perspective a control handle of a mechanism

  motor vehicle door lock.

  The handle 10 comprises in particular a base 12 intended to be received in an opening of a door panel (not shown) on the external face of which it is

  in contact by a bearing surface 14.

  A control pallet 16 is articulated on the base 12, around a hinge axis A1 vertical and parallel to the plane of the door panel, between a position

  rest and an unlocked position.

  The pallet 16 is provided with an arm 18 for controlling the locking mechanism (not shown) intended to pass through the base 12 through a passage 15 of the base 12 provided for this purpose, as well as a spring (not shown) )

  back to its rest position.

  Two cylindrical pins 20A and 20B are articulated on the base 12 between a mounting position and a

fixing position.

  The cylindrical pins 20A and 20B are articulated with respect to the base 12 around their respective axes A2 and A3, parallel and substantially perpendicular to the

bearing surface 14 of the base 12.

  The pins 20A and 20B carry, at their free ends 22A, 22B, each three fingers 24A and 24B, arranged perpendicular to the axes A2 and A3 of the pins 20A, 20B

  and angularly distributed evenly.

  The pins 20A, 20B are also provided with a

  radial lever 26A, 26B for their rotation control.

  A cylindrical return 28 is rotatably mounted on the base 12, around its axis A4 substantially perpendicular to the bearing surface 14 and arranged between

pins 20A and 20B.

  Reference 28 is provided with two radial crankpins 36

and 50.

  The crank pins 36 and 50 of the reference 28 as well as the levers 26A and 26B of the pins 20A and 20B are located substantially in the same plane parallel to the plane of the

  door panel and perpendicular to axes A2, A3 and A4.

  The pallet 16 controls the rotation of the reference 28 by a rigid rod 30, of constant length, which is articulated at the free end 32 of the arm 18 of the pallet 16 and at the free end 34 of the crank pin 36 of the

reference 28.

  The crank pin 36 of the reference 28 is connected to the lever 26A

  of pin 22A by a rod 38 forming a tie rod.

  The tie rod 38 is composed of a slide 40 which is articulated on the free end 34 of the crank pin 36, around an axis parallel to the axis A4, and which is mounted in a slide 42 articulated on the free end of the

  lever 26A around an axis parallel to the axis A2.

  The slide 40 is provided with a stop 44 so as to be able to exert a tensile force on the

  slide 42 and therefore on the lever 26A.

  The reference 28 controls the pin 22B by a rod 46 forming a pusher which comprises a blind sleeve 48 articulated about an axis parallel to the axis A4, on the free end of the second crank pin 50 of the reference 28, and which comprises a rod 52 sliding axially in the sleeve 48 and which is articulated on the free end of the lever 26B of the pin 22B, about an axis parallel to the axis A3. The rod 52 can come into abutment against the bottom of the sheath so that it can push the

  rod and, therefore, the lever 26B.

  FIGS. 3A, 3B, 3C show the operating principle of a fixing system

  using a rotary pin with three radial fingers.

  Elements identical or similar to those represented in the preceding figures are designated by

the same reference figures.

  The pin 20 is presented in the mounting position facing a light 55 formed in a sheet 54 and intended for the passage of the end 22 carrying the fingers 24 of the pin 20. The light 55 has for this purpose a circular shape in its central part and it is provided with as many radial cuts 57 as there are fingers 24

on counter 20.

  Radial notches 56 are formed on the internal surface 53 of the sheet metal 54, between each notch 57, each of which has a shape complementary to the cylindrical lateral face of the fingers 24 of the pin 20 and each of which constitutes a rotation locking notch of a finger. Between a notch 57 and a notch 56, the sheet metal 54 is curved so as to produce a ramp 59. The plane of the notches 57 and the plane of the notches 56 are thus

slightly offset.

  The pin 20 can be introduced axially through the sheet 54, as shown in FIG. 3B, and a control member (not shown) acting on the lever 26 causes the pin 20 to rotate so as to bring the fingers 24 into the notches 56 of the sheet metal 54 which allow the pin 20 to be locked in position

of fixing (see figure 3C).

  The pin 20 thus finds itself in abutment against the sheet 54, it can no longer be removed and an effect of

  tightening of the sheet 54 along the axis of the pin 20 is obtained.

  On the handle shown in FIGS. 1, 2A and 2B, the members for controlling the rotation of the pins 20A,

  B are respectively the tie rod 38 and the pusher 46.

  When the pin 20A is in the mounting position, as in FIG. 2A, the tie rod 38 is arranged so that the stop 44 of the slide 40 cooperates with the slide 42. During the rotation of the pins 20A and 20B, by a sixth in turn, the fingers 24 are supported by their lateral faces on the curved planes 59, which causes a slight axial displacement of the pins 20A, 20B suitable for ensuring the tightening of the handle 10 on the external face of the

door panel.

  Before mounting, the handle is assembled

  with its pins 20A and 20B arranged in the mounting position.

  For its assembly, the handle 10 is brought so that the pins 20A, 20B are found facing the corresponding slots 55 of the sheet metal 54 of the door panel. The pins 20A, 20b are introduced axially into the slots 55 until the bearing surface 14 of the base 12 of the handle 10 is pressed against the sheet

door panel.

  When the pallet 16 is actuated for the first time between its rest position and its unlocked position, the arm 18 of the pallet 16 pivots clockwise, considering FIG. 2A, causing, by

  the rod 30, the return 28 rotating clockwise.

  The reference 28 causes the pin 20A to rotate by pulling on the tie rod 38. The pin 20A is thus found

in fixing position.

  When the pallet 16 is released and returns to its rest position, the return 28 returns to the position

  initial as shown in Figure 2B.

  However, during this return movement, the slide 40 is free to move in the slide 42 which prevents transmission of the movement to the pin 20A

  which thus remains permanently in the fixing position.

  Likewise, the pin 20B is rotated to its fixing position by the return

  28 via the pusher 46.

  Indeed, when the pin 20B is in the mounting position, the rod 52 is in abutment at the bottom of the sheath 48

  as shown in Figure 2A.

  When the pallet 16 is actuated for the first time, the reference 28 pushes the sheath 48 and the rod 52 and therefore causes the rotation of the pin 20B until

its fixing position.

  When the pallet 16 returns to the rest position, the reference 28 brings with it the sheath 48 but the rod 52 slides inside the sheath and does not transmit

  no movement at pin 22B, as shown in Figure 2B.

  The device described therefore allows, during the first passage of the pallet 16 from its rest position to its unlocking position, to cause the simultaneous rotation of the pins 20A and 20B from their mounting position to their fixing position, at the following which the successive movements of the pallet 16 do not

  no longer have any effect on pins 20A, 20B.

  Once the pallet 16 is released, the handle 10 is

fixed on the door.

  There is shown in Figures 4 and 5 a second embodiment of a door handle according to the invention. Elements identical or similar to those represented in the preceding figures are designated by

the same reference figures.

  We find a door handle 10 comprising a base 12 on which is hinged a pallet 16 around an axis A1 horizontal and parallel to the plane of the panel.

  door. The axis A1 is materialized by a rod 61.

  Pallet 16 is provided with a return spring 58

towards its rest position.

  This door handle 10 is intended to be fixed using a pin 20 as described above.

  in a sheet metal 54 provided with a light 55.

  It should be noted that in this case, a single pin 20 is used for fixing the handle 10. To actuate the pin there is provided a vertical link 60, articulated at its ends around two rods 68, 70 of respective axes A5 and A6 parallel to A1, respectively on an arm 18 of the pallet 16 and on a

slide 62.

  The slide 62, which vertically extends the link 60, is provided with a vertical oblong hole 63 constituting a lumen in which a

  stop 64 linked to lever 26 of pin 20.

  As shown in Figure 5, in the mounting position, the stop 64 cooperates with the end

upper 66 of the oblong hole 63.

  For mounting, the pin 20 is introduced into the

  light 55 made in sheet metal 54.

  The pallet is brought from its rest position to its

unlock position.

  The link 60 and the slide 62 are then pushed downwards considering FIG. 5 and

  cause clockwise rotation, considering

in Figure 5, from pawn 20.

  The pin 20 is thus brought into the fixing position. When the pallet 16 is returned to its rest position, the stop 64 of the lever 26 is free to slide in the oblong hole 63 and the return movement of the link is not transmitted to the pin 20. Similarly, the successive subsequent movements of the pallet 16, of the link 60 and of the slide 62 do not affect the

position of the pin 20.

  There is shown in Figures 6 and 7 a third embodiment of a door handle according to the invention. Elements similar or identical to those represented in the preceding figures are designated by

the same reference figures.

  This embodiment is a variant of the second mode in which the fingers 24 of the pin 20 have been

  replaced by two diametrically opposed arms 72.

  The light 55 made in the sheet 54 has

  a complementary shape of the arms 72.

  The operating mode is identical to that

previously described.

  For tightening the sheet 54, the arms 72 carry, at their free ends, elements (not shown) forming a ramp on their face opposite

sheet 54.

  The t81le 54 <also includes notches (not shown) intended to receive these elements to ensure the rotation of the arms 72 of the pin 20

  when the latter is in the fixing position.
