Description

The present invention relates to a device for mounting and regulating a moving glass or moon in a

automotive vehicle door devoid of frame.

In certain motor vehicles, such as cabrio-type coupes, the side doors are devoid of frame.

In the case of the cabrio coupe shown in Figure 1, the side door 1 comprises a movable moon 2 arranged between a fixed front moon 3 and a guard moon 4.

The mobile moon 2 is devoid of a fixed frame.

In this case, it is, however, necessary, at the time of mounting the moon on the door, to be able to control the position of this moon along an axis transverse to the longitudinal axis of the vehicle, in order to ensure proper operation of the moon , a tightness with the edge of the adjacent moons 3, 4, as well as a satisfactory aesthetic appearance.

Figure 2 is an elevation view of the door 1 of the vehicle shown in Figure 1, from which the outer cover plate has been removed.

This Figure 2 shows the fact that the movable moon 2 is guided by a front rail 5 and a rear rail 6, each comprising a cursor 7 that supports the lower part of the moon and that can slide on the rail corresponding between a low position and a high position, such as that shown in Figure 2.

For this purpose, the cursors 7 are dragged, by means of cables, by an electric motor (not shown).

In a known vehicle of this type, the position of the movable moon 2 with respect to the transverse axis of the vehicle is obtained thanks to a piece arranged between the inner lining or lining of the door 1 and the rails 5 and 6.

It has been found that, at the time of tightening the lower fastening of the rear rail 6, the latter can be twisted under the effect of the tightening torque, thereby modifying the position of the movable moon.

Document FR 2,897,587 describes an articulated mounting device of a glass or moon in a frameless door of a cabriolet coupe.

For this purpose, the upper end of one of the guide rails is mounted articulated along an axis parallel to the longitudinal axis of the vehicle, and the lower end of this rail is mounted in an adjustable manner in a direction substantially perpendicular to the rail and the articulation of the upper end of the rail.

In this way, by swinging the rail around the upper articulation axis, the position of the moon can be adjusted so that its upper edge engages or fits well in the ceiling joint.

It is necessary, then, to fix the lower end of the rail by tightening a nut.

However, the tightening torque of this nut can generate a deformation capable of modifying the position of the moon.

The purpose of the present invention is to remedy the aforementioned drawbacks.

This purpose is achieved, in accordance with the invention, thanks to a device for mounting and regulating a moving glass or moon on a motor vehicle door, such that this door is devoid of a frame and is equipped with a front rail and a rear rail comprising, each of them, a cursor intended to support the moon and which can be moved on the corresponding rail, between a low position and a high position, so that at least one of the rails is fixed by its upper part to a first fixed part of the door by means of a pivoting joint along an X axis substantially perpendicular to said rail, and, for its lower part, to a second fixed part of the door, through an adjustable joint in a direction substantially perpendicular to the rail and the X-axis of the pivoting joint, such that said device is characterized in that it comprises a gauge that includes means for arranging it in a geomet position rich of predetermined reference with respect to the door, means for maintaining the upper edge of the moon in the desired geometric position, and means for applying the lower edge of the moon at the cursor of said rail, in the fixing position of this moon to said cursor, such that the lower part of the rail is in this position, free to move by pivot movement around said X axis with respect to said second fixed part, before fixing the lower part of the rail to this second fixed part.

The gauge, in the geometric reference position with respect to the door, thus allows the upper edge of the moon to be maintained in the desired position and to apply the lower edge of this moon on the rail cursor, in the position of fixing the moon to this cursor.

Since the lower part of the rail is free to move, fixing the rail on the cursor causes the pivot movement of the rail around its upper axis, so that the rail position automatically adapts to the position of the moon, the which is, in turn, defined by the gauge.

It is enough then to fix the lower part of the rail in the previously mentioned position, with no other adjustment than this.

Preferably, the gauge comprises means for fixing it on the inner face of the door, at two reference points located, respectively, at the front and at the rear of the door.

These two reference points may correspond to the hole of the lock located at the rear and one of the holes of the joint or hinge located at the front of the door, which constitute precise reference points.

To define the position of the upper edge of the moon with respect to the transverse axis Y of the vehicle, the gauge comprises an organ that comes to rest in a direction Y substantially perpendicular to the moon, against the upper front part of the moon.

Preferably, said organ is adjustable in a Y direction by means of wedges intended, in particular, to compensate for the manufacturing tolerances of the moon.

In one embodiment, the pivotal connection between the upper part of the rail and the first fixed part of the door is constituted by a sheet fixed to this first fixed part and pivotally connected along said X axis to the upper end of said rail.

The rail provided with the front pivot joint can be the rear rail.

The gauge may comprise means to hold the upper leading edge of the moon.

In one embodiment, the first fixed part of the door is constituted by a tensioner of this door.

Preferably, the adjustable joint of the lower part of said rail is constituted by a leg that extends substantially perpendicular to this rail, such that this part comprises an elongated eye-shaped hole in a direction substantially perpendicular to the rail and the axis X of said pivoting joint, arranged at the top of the rail, such that this eyelet-shaped hole is coupled to a threaded rod fixed in a support constituting said second fixed part of the door, so that a nut can be threaded into this threaded rod in order to press said leg against said support.

Likewise, preferably, there is a certain play between said leg and said support and between said threaded rod and said hole in the form of an eyelet, in order to avoid any friction.

This absence of play allows the rail to pivot freely around its axis to adapt to the position of the moon imposed by the gauge after fixing this moon to the rail cursor.

Other particularities and advantages of the invention will become apparent even throughout the description provided in the following.

Figures 3 and 4 represent a device for mounting and regulating a moving glass or moon on a door 1 of a motor vehicle, devoid of a frame and equipped, as in the case of Figure 2, with a front rail 5 and a rear rail 6 comprising, each of them, a cursor 7 intended to support the moon 2, which can be moved on the corresponding rail between a low position and a high position.

As shown by means of Figures 4, 6 and 7, one of the rails is fixed at its top to a first fixed part 8 (see Figure 6) of the door 1 by means of a pivoting joint 9, according to an X axis perpendicular to the rail 6, and, in its lower part, to a second fixed part 10 of the door, by an adjustable joint 11 in a direction substantially perpendicular to the rail 6 and the X of the pivoting joint 9.

According to the invention, the device comprises (see Figures 3 and 4) a gauge 12 comprising means 13 for fixing it in a predetermined geometric reference position with respect to the door 1, means 14 for maintaining the upper edge 2a of the moon 2 in a desired geometric position (i.e., with respect to the transverse axis Y of the vehicle), and means (not shown) to apply the bottom edge 2b of the moon 2 on the cursor 7 of the rail 6, in the fixing position from this moon 2 to cursor 7, as shown in Figures 4 and 7.

In this position, the lower part of the rail 6 is free to move by pivot movement about the X axis with respect to the second fixed part 10, before fixing the lower part of the rail 6 to this second fixed part 10, as will be explained in more detail later.

In order to fix the gauge 12 to the door 1, this gauge comprises means 13 for fixing it to the inner face of the door at two reference points 13a, 13b located, respectively, at the front and at the rear of the door.

These two reference points 13a, 13b can correspond to the hole of the lock located at the back of the door and a hole of the joint or hinge of the front part of the door.

The position of the gauge 12 with respect to the door is thus perfectly defined.

On the other hand, Figures 4 and 5 show the fact that the gauge 12 comprises an organ 14a carried by an arm 14 that comes to rest, according to a direction Y substantially perpendicular to the moon 2, in the upper front part of this moon .

The upper part of the moon 2 is thus held between the support member 14a and a stop 14b (see Figure 4).

The support member 14a is adjustable according to the Y direction by means of wedges in order to compensate for the manufacturing tolerances of the moon 2.

As shown in Figures 6 and 7, the pivoting joint 9 between the rail 6 and the first fixed part 8 of the door 1 is constituted by a sheet 15 fixed to this first fixed part 8 and pivotally connected, according to the X axis, to the upper end of rail 6.

In the example shown, rail 6 is the rear rail.

On the other hand, the first fixed part 8 of the door is constituted by a tensioner that extends between the rear edge and the front edge of the door.

Figures 6 and 7 also show the cursor 7, slidably mounted on the rail 6.

This cursor 7 is located at the top of the rail and comprises a flat face against which the lower edge 2b of the moon 2 can be supported (see Figure 7).

The lower edge of the cursor 7 comprises a hook 16 (see Figure 6) intended to retain the lower edge of the moon.

The means for dragging the cursor 7 between the base position and the high position represented in Figures 6 and 7 have not been represented, since these are well known to the person skilled in the art.

Figure 8 shows the fact that the adjustable joint 11 of the lower part of the rail 6 is constituted by a leg 17 that extends substantially perpendicular to this rail.

This leg 17 comprises a hole 18 in the form of an elongated eyelet in a direction substantially perpendicular to the rail and to the pivot axis X of the pivoting joint 9 disposed in the upper part of the rail 6.

This eyelet-shaped hole 18 is coupled to a threaded rod 19, fixed to a support 10 that constitutes the second fixed part of the door.

A nut 20 can be screwed into this threaded rod 19 in order to tighten the leg 17 against the support 10.

There is a certain play between the leg 17 and the support 10 and between the threaded rod 19 and the edges of the eyelet-shaped hole 18, in order to avoid any friction, so that the rail 6 can pivot freely around the axis X, between two angular positions defined by the opposite ends of the hole 18.

The nut 20 can be equipped with a captive washer that allows, when tightening the nut on the leg 17, to prevent the tightening torque from pivoting the rail 6 in the direction of its length, which would modify the position of the moon 2

To assemble and adjust the position of the moon 2 on the door 1, proceed as follows.

The gauge 12 is first placed in position with respect to the door, with the help of fixing means, such as 13, arranged to obtain a reproducible geometric reference position with respect to the door.

The glass or moon 2 is installed on the top of the gauge 12 in such a way that the support member 14a is resting against the upper rear part of the moon and that the lower edge of the moon is resting against the cursor 7, and that the fixing hole 2c of the moon 2 is in front of the fixing hole 16a of the cursor 7.

In this position, the moon 2 occupies a geometric position corresponding to the desired one, which is imposed by the gauge 12.

The lower part of the moon 2 can then be fixed to the cursor 7 by means of a fixing member that crosses the holes 2c and 16a.

This fixation has the effect of applying the flat face of the cursor 7 against the flat face of the moon 2, which pivots the rail 6 around the X axis to position this in alignment with the support plane.

This pivot movement of the rail 6 is possible thanks to the absence of friction between the leg 7 and the support 10 and between the elongated hole 18 and the threaded rod 19.

In this way, the position of rail 6 is automatically regulated, without manual operator intervention.

The support member 14a has to be raised again and then put back in its place on the moon before the leg is tightened 17. This operation allows the restrictions to be limited to limit the dispersions.

It is enough, then, to tighten the leg 17 against the support 10 when screwing the nut 20 on the threaded rod 19.

The tightening torque applied to the nut 20 does not entail the risk of changing the position of the rail 6 thanks to the washer from which the nut 20 is provided.

The nut 2 regulated thanks to the device according to the invention, has a position essentially along a transverse axis Y with respect to the longitudinal axis of the vehicle, which is perfectly controlled and which, in fact, guarantees a correct operation of the moon, the tightness with the adjacent moons and a completely satisfactory aesthetic appearance.
