Abstract

They comprise a frame (3) suitable for being fixed to the door (2) of a vehicle, a control pallet (4) articulated around said frame and means (7) for damping the return of the tilting control pallet ( 4) in its rest position.

Description

The present invention relates to door handles having a frame

  adapted to be fixed on the door of a vehicle and a pallet articulated around said frame for controlling the lock mechanism. Known door handles of this type generally comprise a one-piece assembly made of molded plastic material. This assembly includes a frame adapted to be fixed to the door of a motor vehicle and a control pallet connected by a semi-rigid joint This joint is made of plastic and is an integral part of the frame and the control pallet so as to create an elastic return of the latter in

rest position.

  Such a door handle has some disadvantages with respect to the recall of the palette which is much too fast and

  In fact, the joint is subjected to elastic deformation

  that may break with repeated effort.

  It is these disadvantages that the present invention intends to remedy more particularly, which essentially consists in associating with the pallet means suitable for damping the return movement thereof.

  from its open position to its rest position.

  The attached drawing, given as an example, will allow for better

  take the invention, the characteristics it presents and the advantages

  tages it is likely to provide: Fig 1 is a perspective view with tearing illustrating

  a vehicle door with a door handle according to the

this invention.

  Fig 2 and 3 are sections showing the cylinder during the

  manipulation of the control pallet.

  Fig 4 and 5 are sections similar to those of fig 2 and

  3, but showing the cylinder when damping the recall of the

  control panel in the rest position.

  FIG. 1 shows a vehicle door I which comprises a cut-out for the installation of a door handle 2 made of molded plastic material. This handle comprises a frame 3 which is fixed on the door 1 and which is hollowed out. a recess 3a C-shaped The latter is delimited on its outer circumference by a vertical face 3b The upper part 3c of the recess 3a is integral with two ears

  vertical 3 d and 3 e which are planned parallel.

  In the frame 3 is associated a tilting control pallet 4 which comprises two vertical flanges 4a and 4b parallel and connected to each other via a horizontal crossbar 4c The control pallet 4 is introduced to the interior of the recess 3 has so that its outer face is in the same plane as the vertical face 3b of the frame 3 In this position, the vertical cheeks 4 and 4 are respectively arranged parallel and close ears 3 d and

  3rd of the frame 3 so that they are joined to them through

of an axis of rotation 5.

  The axis of rotation 5 is resiliently loaded by means of a spring 6, one end bears against the cross member 4c, while the other end bears against the upper part 3c of the recess This elastic return makes it possible to return the control pallet 4 to the rest position after each use, as it is

will see better later.

  The vertical cheek referenced 4a of the pallet 4 is integral with a horizontal axis 4d which is provided opposite the crossbar 4c The ear 3d being close to the cheek 4a has a horizontal axis 3 f

following the same direction.

  A jack 7 is provided free to pivot around the rotational axes.

  4 d and 3 f to follow the movements of the control pallet 4

compared to the framework 3.

  In FIGS. 2 to 5, cylinder 7 is shown which comprises a cymbal body

  lindrique 7 is completely sealed against external pressures, which body is free to pivot around the horizontal axis 4 d of the pallet

tilting 4.

  Inside the cylindrical body 7 slides a rod 7b which is integral with one of its ends with a piston 7c, while the other end is pivotally mounted around the axis 3f of the fixed frame 3 The piston 7c, which has an outside diameter slightly smaller than the internal diameter of the cylindrical body 7a of the jack 7, is hollowed around its circumference with a circular groove 7d which is delimited by two disks 7e and 7f, the disk 7 f being pierced with slots or grooves 7 g which,

  in the example shown, are four in number.

  Inside the circular groove 7 d is placed an O-ring 8 which bears on the one hand against the inner wall of the body

  cylindrical 7a and secondly against the bottom 7h of said groove.

  Slots 7 g are dimensioned and profiled so as to come

  plug in the circular groove 7 d at a distance from the disk 7 f that is

  greater than the diameter of the O-ring 8.

  Note that when the control pallet 4 is tilted Lee towards the outside of the frame 3 for the opening of the door

  1, the body 7 of the cylinder 7 moves along the arrow F 1 of FIG.

  Thus, the height of the circular groove 7 d allows the O-ring 8 to abut against the disk 7 f in order to release the slots 7 g. This release allows the free movement of air inside the cylinder 7 and thus allows a quick and easy operation of the light.

  control pallet 4 with respect to the fixed frame 3.

  On the other hand, when the control pallet 4 is released, it is returned to the rest position by means of the spring 6 whose return force is damped by the presence of the cylinder 7. moves relative to the rod 7b according to the arrow F 2 of

  Fig 5, since this body is mounted on the control pallet 4.

  Note that the O-ring 8 is pushed against the disk 7 e

  piston 7, to slow down the flow of air inside the

  In this case, the return movement of the pallet of com-

  Mande 4 is cushioned, which avoids any loud snapping.

  Note that it is possible to combine the cylinder 7 with another jack placed opposite on the other cheek 4 b of the pallet 4

  and on the corresponding ear of the frame 3 described above.

  It must, moreover, be understood that the foregoing description

  been given only as an example and that it does not limit in any way the

  not of the invention of which one would not go out by replacing the details

  described by any other equivalent.

R EV END I C AT IONS

  1 door handle, of the kind comprising a frame (3) adapted to be

  attached to the door (1) of a motor vehicle, and a pallet of

  tilting device (4) connected by an axis of rotation (5) to said frame for controlling the lock mechanism, characterized in that it comprises means for damping the return movement of the pallet (4)

  from its open position to its rest position.

  Door handle according to Claim 1, characterized in that the frame (3) has a C-shaped recess (3 a) whose upper part (3 c) is provided with two vertical ears (3 d and 3 e). , while the control pallet (4), provided with two vertical cheeks (4a and 4b) connected by a horizontal crossbar (4c), is disposed inside the recess (3a) in the form of C so that its cheeks (4a and 4b) are parallel to the ears (3d, 3e) to be assembled to them via a part of the horizontal axis (5) loaded elastically, on the other hand at least one jack (7) whose body (7 a) is free to pivot about a horizontal axis (4 d) integral with one of the flanges (4 a) of the pallet (4) , the movable rod (7b) of this jack cooperating with another horizontal axis (3f) provided fixed in the ear

neighbor (3 d).

  Door handle according to Claim 2, characterized in that

  that the cylindrical body (7a) of the cylinder (7) is completely watertight, tan-

  say that the movable rod (7b) is integral with one of its ends

  free of a piston (7 c) whose external diameter is slightly less than

  the inner diameter of the body (7a), which piston is hollowed out with a circular groove (7d) delimited by two disks (7e, 7f), one of which is pierced with slots or grooves (7g) in order to said groove communicates with one of the faces of the piston (7c), said groove receiving an O-ring (8) arranged so that during the handling of the control pallet (4), it is pushed against the disc (7 f) above to release the slots (7 e) to allow a free passage to the air, while during the return stroke of the control pallet (4) to its rest position, this seal (8) is pushed back against the other disc (7 th) to slow down the air circulation inside
