Description

The present invention relates to a handle for a vehicle door to

  motor adapted to be removably mounted on the door. Normally, the door handle assembly of a motor vehicle includes a handle attached to a lock actuator, which is pivotally actuated to a bracket removably attached in a suitable housing in the door. For the assembly and disassembly of known door supports on the door, it is necessary to simultaneously act from the inside and the outside of the door. This operation is therefore difficult, particularly in the event of repair or replacement of the assembly since, as, on the one hand, it is necessary to previously deposit the lining of the door, and, on the other hand, it is necessary to position the fasteners on two sides of the door, it is necessary to keep during the operation the door open, which has a tendency to turn

on its hinges.

  The object of the invention is to provide a handle for a motor vehicle which greatly simplifies the assembly and disassembly operations, and allows these operations to be carried out.

  working only on one side of the door.

  This can be kept motionless during

  these operations, for example in the closed position.

  This objective is achieved by a handle according to the invention, which comprises a support adapted to be fixed in a housing of the door, a member actuated in rotation on said support for actuating the lock of the door, and a fixed handle said organ, and is characterized in that said support is removably attached to said housing by fastening means accessible only from outside the door. According to another characteristic of the invention, said fixing means comprise at least one screw adapted to engage from the outside in a corresponding hole of said support and to be screwed into a threaded hole of a holding element, said housing being provided with an opening to allow said screw, partially screwed on said holding member, to be inserted from outside said support, said support having means for locking said member in said housing and preventing it from rotating. To better understand the features of the invention, a preferred embodiment and several associated variants are now described, by way of nonlimiting example, with reference to the accompanying drawings, or: FIG. 1 is a rear view of FIG. a handle according to a first embodiment of the invention, partially mounted on a door of a motor vehicle; Figure 2 is a vertical section along the line II-II of Figure 1; - Figure 3 is another vertical section along the line III-III of Figure 1; Figure 4 is a horizontal section along the line IV-IV of Figure 1; - Figure 5 is a vertical section along the line V-V of Figure 1; Fig. 6 is another vertical section along the line VI-VI of Fig. 1; FIG. 7 is a rear view of a handle showing a variant of the embodiment illustrated in FIGS. 1 to 6, mounted on a door; - Figure 8 is a horizontal section along the line VIII-VIII of Figure 7 in partially mounted condition; Figure 9 is a vertical section along the line IX-IX of Figure 7; Fig. 10 is another vertical section along line X-X of Fig. 7; Fig. 11 is an additional vertical section along line XI-XI of Fig. 7; FIG. 12 is an external exploded perspective view of a handle and the corresponding housing in the door showing another embodiment of the invention; - Figure 13 is a horizontal section of a detail of the handle of Figure 12; - Figure 14 is a vertical section of another detail of the handle of Figure 12; FIG. 15 is a horizontal section of a handle formed according to a variant of the embodiment illustrated in FIG. 12; Fig. 16 is a vertical section along line XVIXVI of Fig. 15; Fig. 17 is another vertical section along the line XVII-XVII of Fig. 15; and - Figure 18 is an additional vertical section along the line XVIII-XVIII of

Figure 15.

  With reference to FIGS. 1 to 6, reference numeral 20 denotes the metal sheet structure of a motor vehicle, for example an automobile. The structure 20 includes a housing, generally designated 21, adapted to house a handle assembly 22, which will be hereinafter simply referred to as "the handle". The door also carries a glass pane 19 (see FIGS. 2 to 6) and is lined internally with a panel

  which covers the different mechanisms.

  The handle 22 essentially comprises a support 23 of complex shape, made of a light alloy or a very strong plastic, which is the part of the handle by which the latter is fixed to the housing 21. The handle 22 further comprises a pivoting member 24 for actuating the lock of the door, not visible in Figures 1 to 6. The member 24 is preferably made of the same material

  that the support 23 and can rotate on the latter.

  On the member 24 is fixed a handle 26, preferably made of a metallized plastic material,

  for the actuation of the member 24 itself.

  The housing 21 is constituted by a hollow area 27 (see Figures 2, 3, 5 and 6) to allow the user to manually enter the door handle 26. The housing 21 is provided with a wide opening (see Figure 1 ) of substantially rectangular shape, to allow the application, from the outside, of all

  constituted by the support 23 and the member 24.

  The opening 28 has side edges 29 (see FIG. 4) and horizontal formed edges 31 (see FIGS. 2 and 3), the shape being such that it allows the engagement of the edges

  corresponding 32 and 33 of the support 23.

  The member 24 is constituted by a cross member 34 having two lateral arms 35 each having a transverse hole, in which is engaged a rocket or fulcrum 36 carried by two advances 37 (see Figures 1 and 6) of the support 23 One end 39 of a torsion spring 38 is engaged with the cross member 34, the other end 40 being engaged in a slot of the support 23. The spring 38 normally holds the member 24 in its rest position. indicated in solid lines in the figures, an edge 126 of the handle 26 resting against a

advanced support 23.

  The member 24 carries a channel 42, corresponding to each arm 35 (see Figures 1, 2 and 4), in which are engaged a pair of elastic hooking tongues 43 integral with the handle 26. The handle is fixed on the member 24 by inserting two seals 44 disposed on the outer edge of the two channels 42, from outside the door, simply by introducing the languages 43 into the channels 42 and exerting a pressure on the handle 26 until the hooking ends of the tongues 43 engage beyond the edge of the channel 42 in the

  position shown in Figure 4.

  The support 23 comprises two housings 45 for receiving two screws 46 for fixing the support 23 to the structure 20 of the door. the housings 45 are equidistant from the axis of the spindle 36 and are each constituted by a bottom wall 47 connected to the support 23 by means of a substantially cylindrical wall 48. The wall 47 is flat and pierced with a lateral slot in

  shape of C. Part of wall 48 extends beyond

  beyond the flat wall 47 to form a projection 49 having two edges 50 and 51 with complementary cam profiles of substantially helical shape. Each housing 45 further comprises an elastic advance 52 adapted to cooperate with the head of the corresponding screw 46, both to maintain it in engagement against the wall 47 of the housing 45 and to prevent easy unscrewing of the screw 46 due to vibrations motor during the use of the motor vehicle. Each screw 46 is adapted to be screwed into a threaded hole of a holding member consisting of a metal plate of rectangular shape 53 and of longitudinal section C-shaped (see Figures 1, 4 and). The length of the plate 53 is greater than the height of the opening 28 and is such that two chamfered ends 54 of the two arms of the plate 53 can engage inside the two formed edges 31 of the opening 28. The assembly of the handle 22 on the structure 20 of the

  door is made in the following manner.

  The handle assembly 22 being assembled, the handle 26 is firstly separated from the member 24 by pressing the latching tongues 43 of the handle 26 and out of the channels 42. Then the screws 46 are inserted into the respective housings 45 and screwed on several turns in the holes

corresponding trays 53.

  When the ends of the screws 46 have been screwed over the entire thickness of the plate 53, as indicated in FIGS. 1 and 4 for the left screw 46, one of the lateral edges of the plate 53 engages the end portion of two cam edges 50 and 51 taking a position parallel to the spindle 36. With the two trays 53 in this position, the support 23, with the member 24 pivoted and the trays 53, is introduced into the opening 28 of the housing 21 by the outside of the structure 20. The support 23 is then engaged with the edges 32 and 33 against the edges 29 and 31 of

the opening 28 itself.

  Then, the two screws are turned from the outside. Each screw 46 then tends to pull the corresponding plate 53 in rotation in the counterclockwise direction, but as this rotation is limited by the profile of the edge 50, the plate can rotate only gradually while it advances axially . The complementary shape of the edge 51 contributes positively to this rotation. It should be noted that when the screws 46 are unscrewed, the two complementary shaped edges 50 and 51 are further adapted to rotate the respective plate 53 positively in a clockwise direction, thereby allowing easy removal. of

the handle 22.

  After a certain displacement of the plate 53, it has turned 90 degrees relative to the initial position, as indicated by FIGS. 1 and 4 for the right plate 53. The two chamfered ends 54 remain hooked inside the structure 20 over the edges 31 of the opening 28. Each screw 46 can then be screwed further to bring the two ends 54 against the edges 31 as shown in the figure, and firmly hold the plate 53 against the flat wall 47 of the 45. The edges 31 of the opening 28 thus remain tight between the chamfered ends 54 of the plate 53 and the

edge 33 of the support 23.

  Finally, still by acting from the outside of the door, the tongues 43 are introduced into the channels 42 of the handle 26 (see FIG. 4), by fixing it to the member 24, as previously seen. . In FIGS. 1 and 4, for illustrative purposes only, the left plate 53 is indicated in its initial position even if the handle 26 is illustrated as

being attached to the organ 24.

  It is therefore obvious that the support 23 of the handle 22 is removably fixed in the housing 21 by the fixing means 46, 53 which are accessible only from outside the

motor vehicle.

  In the variant illustrated in FIGS. 7 to 11, the elements having a function similar to those of FIGS. 1 to 6 have been designated in the figures by the same references, and their

  description will not be repeated. In this

  alternatively, the support 23 carries two housings 55 for the screws 46, which consist of two equidistantly pierced depressions equidistant from the spindle 36. The support 23 is provided with two advances comprising two edges 56 and 57 parallel to the axis of the screw 46, which are designed to cooperate with an edge of the

corresponding tray 53.

  The assembly of the handle illustrated in FIGS. 7 to 11 is made from the outside in a manner similar to that described for the handle illustrated in FIGS. 1 to 6. In particular, after having separated the handle 26 from the member 24, the screws 46 are introduced into the housings 55 and penetrate into the mouths of the holes of the trays 53. By keeping these parallel to the spindle 36, as indicated in FIG. 8 for the left plate 53, the support 23, with the member 24 and the plate 53, are introduced into

the opening 28 of the housing 21.

  To screw each screw 46, the housing is first extracted axially over a distance, so as to bring the associated plate 53 axially correspondingly to the edge 56 or 57 respectively. Then, by screwing the screw 46, the associated plate 53 is associated with the rotation until it abuts against the associated edge 56, 57. The following rotation of the screw 46 then only brings the plate 53 of the However, the plate 53 remains engaged with its end 54 inside the structure. This movement of approximation continues until the ends 54 abut against the inside of the edge 31 of the opening 28, as in the previous case. In the two variants described above, the trays 53 are turned 90 degrees from their initial position, parallel to the spindle 36. It is obvious that the edge 31 of the opening 28 of the housing 21 can be designed in such a way it blocks the movement of the plate 53 after a rotation at a different angle, for example, an angle of between 30 degrees and

150 degrees.

  In the embodiment of Figures 12 to 14, the housing 21 of the structure 20 for the handle 22 comprises an opening 58 having an upper zone 59 whose width is larger than the width, smaller, of a lower zone 61 The opening 58 has an edge 62 whose shape allows the engagement of the support 23 of the handle. The edge 62 comprises two lateral parts 63 parallel to each other and arranged to correspond to the lower portion 61 of the opening 58, and a horizontal portion 67 between

both parties 63.

  The support 23 is made of a plastic material and comprises a cross-shaped element 64 of inverted L-shaped section with two chamfered edges 65 parallel to each other and designed to engage the portions 63 of the edge 62 from the outside. The cross member 64 has a lower bearing 66 designed to engage the horizontal portion 67 of the edge 62. The cross member 64 is carried by two upwardly tapered arms 68 and 69, each having a hole 70 for each other. receiving a spindle 71 for pivoting the pivoting member 24. This comprises a pierced upper cross member 72 adapted to be disposed between the two arms 68 and 69 of the support 23. The spindle 71 is inserted into the hole

cross element 72.

  One side of the cross member 72 carries a projection 73 extending laterally inside the structure 20. The spindle 71 has a length such that it extends from the arm 68 to the left, to receive a torsion spring 74, one end 76 of which engages against the projection 73, the other end 77 engaging against the arm 68. The spring 74 normally holds the member 24 engaged against a shoulder of the support 23, not shown in FIG. the figures. The end of the projection 73 is adapted to act on a slider 78 of the lock mechanism 79 (see

Figure 14).

  The member 24 further comprises two channels 81 (see Figure 12) of square section connected by a lower reinforcement 82. Each channel 81 is provided to receive a pair of elastic hooking tongues 83 (see Figure 13) integral with the handle 26 of the handle assembly, which can therefore be connected to the pivoting member 24 in a manner similar to that described for the method of

  embodiment illustrated by Figures 1 to 6.

  To each of the two arms 68 and 69 of the support 23 (see Figure 12) is connected a tongue 84 extending laterally and adapted to engage on the top and sides of the edge 62 of the corresponding portion of the zone 59 advancing from the lower zone 61. Each tongue 84 is further connected to the corresponding arm 68, 69 of a rib

triangular reinforcement 86.

  The central portion of the cross member 64 carries a housing 87 having the shape of a square section channel, intended to be placed in the space between the two channels 81. The housing 87 has a bottom wall pierced so to receive a screw 88, which is housed in the housing 87 with a metal washer 89. The housing 87 is further adapted to receive from the front a small cover 90 for

cover the head of the screw 88.

  A robust vertical tab 91, which carries two lateral tongues, each generally designated 92, is connected to the cross member 64. Each tongue 92 has a substantially rectangular shape and includes a portion 93 of reduced profile to allow, for example, bending, the rotation of the tongue itself relative to the tab 91. Each tongue 92 further comprises a chamfered edge 94 adapted to engage on both edges 63 of the inner portion of the structure 20. At rest, the languages 92 are placed at approximately 45 degrees to

to the axis of the screw 88.

  Each tongue 92 is adapted to cooperate with a holding element for the screw 88, consisting of a metal plate 96. The latter has an inverted T shape and is provided with a threaded hole 97. The plate 96 has two arms 98 adapted to engage on the surface

back of languages 92.

  The assembly of the handle of Figure 12 is made entirely from outside the door. After assembling the support 23 and the pivoted member 24 by means of the spindle 71 and the spring 74, the screw 88 is inserted with the washer 89 into the housing 87 and the screw 88 itself is rotated several turns to the inside the hole 97 of the plate 96 until the two arms 98 engage on the surface

back of languages 92.

  Then, the assembly is introduced into the openings 58 by passing the languages 92 and

  the plate 96 in the zone 61 of the opening 58.

  The arms 68 and 69 of the support 23 and the cross member 72 with the projection 73 are then disposed inside the structure 20, while the two tabs 84 engage against the associated parts of the edge 62, since outside, and that the bearing 66 engages from the outside against the

horizontal portion 67 of the edge 62.

  The screw 88 is then rotated, which moves the plate 96 axially. As this engages the tongues 92, however, the plate can not follow the rotation of the screw 88. By means of the arms 98, the plate 96 makes the tongues disassociate. 92 until the chamfered edge 94 thereof engages from the inside against the two parts 63 of the edge 62. Therefore, each of these parts 63 remains trapped between the chamfered edge 65 of the element. cross 66 and the chamfered edge 94 of the associated tongue 62. After having screwed the screw 88 on the bottom, the cover 90 is inserted by friction into the housing 87 and the handle 26 is fixed with the attachment languages 83 in the channels 81, as we saw earlier. In the variant of the embodiment of FIG. 12 illustrated in FIGS. 15 to 18, the elements having a function similar to those of FIG. 12 are designated by the same

  encrypted references and their description is not

  repeated. The cross member 64 (see FIGS. 15 and 16) of the support 23 is now substantially flat and is provided with two C-shaped arms 68 'and 69' (see FIG. 16); it is connected to the side tongues 84, not shown in the figures, by means of two triangular reinforcements 86. The housing 87 of the screw 88 projects partially towards the outside of the cross member 64 and is connected to this one by two ribs 99 (see

Figure 15).

  The two languages 92 are connected, by means of the portion 93 of reduced thickness, to a pierced rear wall 100 of the housing 87. Like the chamfered edge 94, they also comprise the shoulder 101 on which the arms 98 of the

  plate 96 act during the clamping step.

  At rest, the tongues 92 may interfere with the inner panel 19, as shown in FIGS. 15 and 17. However, when mounting the handle on the door already equipped with the panel 19, this interference has the sole effect of slightly folding the 92 while inserting the assembly 23, 24 into the housing 21. Another possibility is to turn the screw 88 before inserting the assembly 23, 24 into the housing 21, so as to eliminate the separation between the tongues 92 and the arms 98 due to the engagement of the languages 92 with the panel 19. It is obvious that the handles described may receive various modifications and improvements without departing from the scope of the invention. For example, the handles of FIGS. 1 to 11 may be equipped with a single fixing screw 46. In addition, for the handles of FIGS. 12 to 18, the support 23 may be provided with more than two separable tongues 92 and the plate 96

  can carry a corresponding number of arms 98.
