Description

The invention relates to a hinge assembly for hinging a rear wing door of a vehicle.

In particular, an object of the invention is a hinge assembly for hinging a rear wing door of a vehicle with a rear vertical strut of a body structure of said vehicle, comprising a first hinge portion adapted to be mounted on a door and a second hinge portion adapted to be mounted on a rear rack wherein said second hinge portion is secured with screws that extend successively from the outside inward through said second hinge part through holes in the wall of the rear pillar, through holes in the reinforcing plate, and through at least three recessed nuts, each of which is in the platform and at least two of which are fixedly connected to each other.

Many examples of hinge assemblies are known.

In the known hinge assembly in the mounting plate, usually all recessed nuts are located, and this plate rigidly connects them to each other.

This design has a drawback. Indeed, during installation of the hinge, the screws are usually installed one after the other. Therefore, the introduction and tightening of the first screw leads to the rotation of the mounting plate, in which the other recessed nuts are displaced and are no longer in line with the holes of the reinforcement plate and the wall of the rear rack.

The objective of the invention is to eliminate this drawback by creating a hinge assembly in which at least one recessed nut designed to install the first screw is independent of the others.

The problem is solved in the hinge assembly, which, according to the invention, contains a mounting assembly containing a first platform, in which a first recessed nut is installed, designed to insert the first screw, which should be installed and tightened before other screws, and a second platform independent of the first platform in which second recessed nuts are provided for inserting other screws to prevent said second nuts from shifting relative to the openings of the wall of the rear pillar and the holes of the reinforcement tion plate after tightening the first screw into the first nut.

According to other features of the invention:

- The hinge assembly comprises a support plate configured to lock it relative to the vehicle body structure and interact with the first and second platforms of the mounting assembly to block rotation of the first and second recessed nuts.

- The reinforcing plate contains at least one shelf designed to fit from the inside to the wall of the rear pillar of the body structure, which is oriented in the continuation of the side wall of the vehicle, and the support plate contains:

- part of the bent sheet containing at least one shelf designed to fit from the inside to the shelf of the reinforcing plate,

- the wall of the part containing the outer side, on which the supporting sides of the walls of the first and second platforms are locked.

- The first and second recessed nuts protrude from the supporting sides of the first and second pads, and the wall of the base plate contains cutouts made with the possibility of installing said recessed nuts in them.

- The first and second recessed nuts extend into the corresponding free sides of the first and second walls.

- The second and third recessed nuts extend into the free side of the second wall.

- The second wall of the second platform contains a concave cutout corresponding in shape to the convex cutout of the first wall of the first platform, which is configured to provide relative positioning of the sites.

- The first platform contains two protrusions made on the sides of the side of the specified platform opposite to its convex cut and containing a common rectilinear edge, and the base plate contains a protruding foot located in the immediate vicinity of the common rectilinear edge, and two protruding tabs located in the immediate vicinity of each from the opposite edges of the protrusions, for locking the first platform relative to the support plate, in particular, while screwing the corresponding screw.

- Each protruding tab is made by making a cutout in the base plate and folding in a direction perpendicular to the plane of the base plate.

- Each protruding foot is made during the cutout in the plate and bent at its edge.

Other features and advantages of the invention will be more apparent from the following detailed description with reference to the accompanying drawings.

In FIG. 1 is a rear perspective view of a van-type motor vehicle comprising a hinge assembly in accordance with the invention;

in FIG. 2 and 3 show a side view from the inside illustrating the rotation of the known mounting plate while tightening the screw;

in FIG. Figure 4 shows a perspective view of the pads intended for the installation of countersunk nuts in accordance with the invention;

in FIG. Figure 5 shows a perspective view of the pads intended to be used to install recessed nuts and the corresponding plate in accordance with the invention;

in FIG. 6 is an exploded perspective view of a hinge assembly in accordance with the invention.

In FIG. 1 shows the rear side of a van type vehicle 10. As is known, the vehicle 10 comprises a body structure 12 including a rear vertical strut 14 on which the rear wing door 13 is mounted. The rear wing door 13 is pivotally mounted on the rear vertical strut 14, preferably with two hinge assemblies 16.

As shown in FIG. 6, the hinge assembly 16 comprises a first hinge part 18, which is mounted on the door 13, and a second hinge part 20, which is mounted on the rear rack 14.

As is known and shown in FIG. 6, the second hinge part 20 is fastened with screws 22, which pass successively through the specified second hinge part 20, through the holes 23 of the wall 24 of the rear pillar 14 and through the holes 25 of the reinforcement plate 26.

Then, as shown in FIG. 2, the screws pass through a mounting assembly 32 consisting of three recessed nuts 32a, 32b, 32c joined by a support plate 30. The screws 22 go into the recessed nuts, as shown in FIG. 2.

The support plate 30 and the recessed nuts are shown in FIG. 2 and 3, which also shows a plate 30 located on the rear side of the amplification plate 26.

The recessed nuts 32a, 32b, 32c belong to the same assembly 32. Thus, the support plate 30 in which the recessed nuts 32a, 32b, 32c are mounted rigidly connects them to each other.

This design has a drawback. Indeed, during installation of the hinge 16, screws 22 are usually installed one after the other. However, as noted, the insertion and tightening of the first screw 22 in the nut 32a leads to the rotation of the mounting plate 30, in which the other recessed nuts 32b, 32c are displaced and are not in the same line with the holes 25 of the reinforcement plate 26 and with the holes 23 of the back wall 24 racks 14, as shown in FIG. 3.

To eliminate this drawback, one solution is to separately execute and lock the first recessed nut 32a, which should be tightened before the other recessed nuts 32b, 32c.

To this end, the invention has proposed the hinge assembly described above, which comprises a fastening assembly 32 comprising a first pad 46 in which a first recessed nut 32a is installed, for inserting a first screw 22a, which should be installed and tightened before other screws 22b, 22c, and a second pad 50, independent of the first platform in which the second countersunk nuts 32b, 32c are installed, for inserting the other screws 22b, 22c to avoid biasing said second nuts 32b, 32c relative to the holes 23 of the wall 24 and to open steps 25 of the reinforcement plate 26.

The support plate 30, made with the possibility of locking relative to the body structure of the vehicle, interacts with the first and second platforms 46, 50 of the mounting unit 32 for locking in rotation of the first and second recessed nuts 22a, 22b, 22c.

In a preferred embodiment, as shown in FIG. 6, the reinforcement plate 26 comprises at least one shelf 24 designed to fit from the inside to the wall 36 of the rear pillar 14 shown in FIG. 1, which is located in the continuation of the side wall 37 of the vehicle (not shown).

The support plate 30 comprises at least one portion 33 of bent sheet iron, comprising at least one shelf 38 intended to fit from the inside to the shelf 34 of the reinforcing plate 26. The countersunk nuts 32a, 32b, 32c are adapted to pass through corresponding cutouts 40, 42, 44 made in this part 33 of the sheet.

As shown in FIG. 4 and 5, the first platform 46, on which the first recessed nut 32a is located, comprises a first wall 52, the supporting side 53 of which is locked on the free side 31 of the wall 35 of part 33 of the supporting plate 30, and said first nut 32a passes through its first cutout 40 In particular, the first recessed nut 32a extends into the free side 48 of the first wall 52 to ensure its screwing.

Similarly, the second platform 50, on which the second and third recessed nuts 32b, 32c are located, contains a second wall 54, the supporting side 55 of which is locked on the free side 31 of the wall 35 of the portion 33 of the support plate 30. The second and third recessed nuts 32b, 32c pass through corresponding second and third cutouts 42, 44. The second and third recessed nuts 32b, 32c extend to the free side 56 of the second wall 54.

As shown in FIG. 4, the second wall 54 has a concave cutout 58 that corresponds in shape to the convex cutout 60 of the first wall 52. These cutouts are configured to provide relative positioning of the pads 46, 50 before inserting the nuts 32a, 32b, 32c into the corresponding cutouts 40, 42, 44 of the support plates 30.

Furthermore, as shown in FIG. 4 and 5, the first platform 46 has two protrusions 62, 64, which are located on the sides of the side 66 of the specified platform 46 opposite to its convex cutout 60 and which have a common straight edge 68.

As shown in FIG. 5 and 6, the plate 30 contains a protruding tab 70 located in the immediate vicinity of the common rectilinear edge 68 of the first platform 46, and two protruding tabs 72, 74 located in the immediate vicinity of each of the opposite edges 76, 78 of the protrusions 62, 64 of the first platform 46 to prevent the first pad 46 from turning while screwing the screw 22 into the recessed nut 32a.

Preferably, each protruding tab 70, 72, 74 is made by cutting in the base plate 30 and folding in a direction perpendicular to the plane of the base plate 30.

In addition, each protruding tab 70, 72, 74 is obtained during the execution of the cut 40, 42, 44 of the plate 30 and bent along the edge of this cut. Thus, the legs are made during the manufacture of the plate 30.

After the insert 30 is put in place on the pads 46, 50 and after it locks the nuts 32a, 32b, 32c, the hinge assembly can be easily assembled by starting by tightening the screw 22 installed in the nut 32a without the risk of turning the plate 30.

Thus, the invention can significantly simplify the installation of the hinge assembly of the rear wing door of a vehicle.
