Definitions

• the present invention relates to a door handle for a fast-mounting motor vehicle.
• the invention relates more particularly to a control handle of a motor vehicle door locking mechanism, of the type comprising a base received in an opening of a door panel, the base comprising a bearing surface against the face external of the door panel, a control pallet which is articulated on the base between a rest position and an unlocking position and which is connected to the locking mechanism, and of the type in which the door panel is clamped between the surface support and a clamping element attached to the base.
• Such devices are known for example from US-A-5 248 175 and implemented, but they require, for the establishment of the clamping element of the base, to be able to access the rear of the handle from the inside of the door.
• the present invention aims to provide a door handle for a motor vehicle capable of being mounted quickly, for example automatically, and without the need for access to the interior of the door.
• the invention provides a control handle for a locking mechanism of the type mentioned above, characterized in that the clamping element of the base is an element mounted to move on the base between a mounting position and a fixing position to which it is moved during assembly of the handle by a link articulated on the pallet, during the first passage of the pallet from the rest position to the unlocking position.
• 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 rest position and an unlocking 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) ) to return 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 relative 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 distributed angularly in a regular manner.
• the pins 20A, 20B are moreover provided with a radial lever 26A, 26B for their rotation control.
• a cylindrical return 28 is mounted for rotation on the base 12, around its axis A4 substantially perpendicular to the bearing surface 14 and arranged between the pins 20A and 20B.
• the reference 28 is provided with two radial crankpins 36 and 50.
• 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 the axes A2, A3 and A4.
• the pallet 16 controls the rotation of the return 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 return 28.
• crank pin 36 of the reference 28 is connected to the lever 26A of the pin 22A by a link 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 abut against the bottom of the sleeve so that the latter can push the rod and, consequently, the lever 26B.
• FIGS. 3A, 3B, 3C show the operating principle of a fastening system using a rotary pin with three radial fingers.
• 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 the pin 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.
• 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 54 which ensure the blocking of the pin 20 in the fixing position (see FIG. 3C).
• the pin 20 is thus found in abutment against the sheet 54, it can no longer be removed and a tightening effect of the sheet 54 along the axis of the pin 20 is obtained.
• the members for controlling the rotation of the pins 20A, 20B are the tie rod 38 and the pusher 46 respectively.
• the tie rod 38 is arranged so that the stop 44 of the slide 40 cooperates with the slide 42.
• 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 handle 10 on the outside of the door panel.
• the handle Prior to mounting, the handle is assembled with its pins 20A and 20B arranged in the mounting position.
• 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 external sheet of the door panel.
• the arm 18 of the pallet 16 pivots clockwise by considering FIG. 2A, driving, by the rod 30, the return 28 in clockwise rotation.
• the reference 28 causes the pin 20A to rotate by pulling on the tie rod 38.
• the pin 20A thus finds itself in the fixing position.
• the pin 20B is driven in rotation, to its fixing position, by the reference 28 via the pusher 46.
• the reference 28 pushes the sheath 48 and the rod 52 and therefore causes the rotation of the pin 20B to its fixing position.
• 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 as a result of which the successive movements of the pallet 16 no longer have any effect on the pins 20A, 20B.
• a door handle 10 having a base 12 on which is hinged a pallet 16 about an axis A1 horizontal and parallel to the plane of the door panel.
• the axis A1 is materialized by a rod 61.
• the pallet 16 is provided with a spring 58 for returning to 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.
• a vertical link 60 is provided, articulated at its ends around two rods 68, 70 with 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 extends vertically from the rod 60, is provided with a vertical oblong hole 63 constituting a slot in which a stop 64 can move, linked to the lever 26 of the pin 20.
• the stop 64 cooperates with the upper end 66 of the oblong hole 63.
• the pin 20 is introduced into the lumen 55 formed in the sheet metal 54.
• the pallet is brought from its rest position to its unlocking position.
• the link 60 and the slide 62 are then pushed downwards when considering FIG. 5 and cause the rotation of the pin 20 in the clockwise direction, considering FIG. 5.
• the pin 20 is thus brought into the fixing position.
• This embodiment is a variant of the second mode in which the fingers 24 of the pin 20 have been replaced by two diametrically opposite arms 72.
• the lumen 55 formed in the sheet 54 has a shape complementary to the arms 72.
• the operating mode is identical to that described above.
• the arms 72 carry, at their free ends, elements (not shown) forming a ramp on their face opposite the sheet 54.
• the sheet 54 also includes notches (not shown) intended to receive these elements in order to block the rotation 72 of the arms 72 of the pin 20 when the latter is in the fixing position.
