Description

Description: FIELD OF THE INVENTION The subject of the invention is the connecting block between a windowpane in a motor vehicle and a window lifting mechanism with a swing arm and the bottom of this block and the associated windowpane. And a device including the part.

[Conventional technology]

The device is of the type that includes a block for each arm that is slidable in a portion articulated on the end piece of the arm and rigidly attached to the bottom of the glazing.

The end pieces of these arms can be constituted by ball joints, for example.

To date, these connections have been done manually and partially blindly on the vehicle assembly line. The positioning of these devices is therefore relatively tedious and cumbersome.

[Problems to be Solved by the Invention]

It is an object of the invention to create a coupling device by which the arm of a window lifter can be automatically assembled by an operating robot.

[Means for solving the problem]

According to the invention, the block is formed by two half blocks, one of which is slidable with respect to the other and provided with means for relative guidance, which half blocks are provided with two blocks.
Three stable positions, i.e. a first position in which this block has a limited degree of freedom of movement relative to the bottom part of the glazing before introducing the end pieces of the arms into the block;
After the introduction of said end piece of the arm and the displacement of one half block by this end piece with respect to the other half block, the end piece of the arm is locked in the block and this block is the bottom part of the windowpane. Means are provided for locking together in a second position, which is free to slide in.

Once the two half blocks have been assembled and introduced into the corresponding part of the bottom of the glazing, this block is in the appropriate housing provided for this block and the end piece of the arm of the window lifter. To make contact with
It is understood that it is only necessary to lower the glazing. It then only requires robotic control of the window lifter arm to move the block from its first stable position to its second stable final position in use.

This automatic assembly can therefore be carried out in a very short time compared to the manual assembly used hitherto.

According to another feature of the invention: the means for locking the two half blocks comprises an elastic element mounted on the opposite ends of the half blocks, which can be clamped on a cooperating stop element (projection). I'm out.

One of these elastic elements is a flexible longitudinal strip of one of the half blocks, defining one recess with the body of this half block, this recess being rigidly attached to the other half block. Stopper strips can be received and the strips can form transverse passages, and the locking stoppers can be provided on the strips or on the wall of the body, between which the stopper pins can lie. This locks the two half blocks in their first stable position.

The strip is provided with laterally projecting end portions.

The second elastic element is the flexible arm of one half block provided with end pawls which can be clamped on the corresponding projection of the other half block, these elements together with the strip and the cooperating pin, Its size and position are such that the pawls do not engage the projections when the pin is pushed between the end stoppers and the pin is completely removed from the strip after one half block slides against the other half block. The strips are sized and positioned so that the pawls do not contact the projections when the strip is returned to its rest position by elastically loosening the lateral passages.

Other features and advantages of the invention will become apparent from the following description of two embodiments given by way of non-limiting example with reference to the accompanying drawings.

〔Example〕

In FIG. 1, a door 1 of a motor vehicle can be seen to which a window glass 2 and a window lifting mechanism 3 having two swing arms 4 on a support housing are attached. The end pieces of the arms 4 are hinged to blocks which are fixed to a U-shaped part 6 which receives the bottom of the windowpane 2.
Can be slid in and the two parts 5 and 6 are rigidly attached to this glazing 2. The end piece 11 of the arm 4 sliding in the block can be a sphere (ball joint) or any other suitable mechanism.

The invention consists of a part 5 and an arm 4 at the bottom of the glazing.
2 and 8 are respectively connected by means of a block device 7 shown in FIGS. 2 to 8 which is hinged on the end piece 11 of the arm 4.

Each block 7 is made up of two half blocks 8 and 9, one of which can slide with respect to the other. For convenience of description, this half block 8 will be referred to hereinafter as the "upper half block", and half block 9 will be referred to as the "lower half block", respectively, when these half blocks are attached to part 5. This is because they are actually placed at the relevant positions. The half blocks 8 and 9 are further provided with means for locking them together in each of the two stable positions, which two positions are
Before the end piece 11 of the arm 4 is introduced into the block 7,
A first so-called "assembled" position in which the freedom of movement with respect to the part 5 of the block 7 is limited, and the end piece 11 is introduced into the block 7 so that the upper half block 8 is in relation to the lower half block 9 And a second, so-called "use" position, after displacement by 11. In fact, in this position the end sphere 11 is locked in the block 7 which can slide freely in the part 5.

These means for locking the two half blocks 8,9 are mounted on opposite ends of these half blocks,
It includes elastic and flexible elements 12 and 13 with which co-stop elements 14 and 15 can be clamped. In this example,
The elastic elements 12 and 13 belong to the lower half block 9 (which can be an integral part of this half block or can be added to it) and the elements 14 and 15 are part of the upper half block 8. Is. The elastic element 12 comprises an end portion 12 which projects a lateral passage and forms a generally right-angled elbow in the remainder thereof.
is a flexible longitudinal strip provided with a. The strip 12 together with the longitudinal fingers 40 of the body 16 of the half block 9 defines an expanded recess 17 in which the pin 14 can be received, and the strip 12 is of the pressure of the pin 14. Originally, the lateral passage is separated. Two notches or stoppers 18, 19 for the pin 14 are provided on the side of the strip 12 defining the recess 17. The pin is in fact arranged between the stoppers 18 and 19, which stop the upper half block 8 and its first relative to the half block 9.
Hold it in its locked, stable position. First stopper 18
Is rounded to allow the pin 14 to pass through, while the second
The stopper 19 is formed with a notch so as to prevent the pin 14 from further advancing.

The second elastic element 13 is a flexible foot to which an end claw 13a having a groove 13b is attached. In its normal position where it is elastically retained, the pawl 13a of the foot 13 is clamped by the corresponding projection 15 engaged in the groove 13b.

The strip 12, the foot 13, the pin 14 and the projection 15 have the claw 13a having the projection 1 when the pin 14 is locked between the stoppers 18 and 19.
When the pin 14 is completely disengaged from the strip 12 after the half block 8 does not engage with the half block 8 and the half block 8 slides against the half block 9, the claw 13a engages with the protrusion 15 and the strip 12 again.
Is positioned and dimensioned to return the cross passage to its rest position (FIG. 7).

Housings 21a, 21b are provided on the two half blocks 8, 9 for receiving the end pieces of the arm 4 and lateral grooves 22 for introducing the end pieces 11 into these housings 21a, 21b. , 23 are provided in blocks 8 and 9, respectively. Since the end piece 11 described in this example is a sphere, the housing 21 provided at the center of the half block 8 is
a has a corresponding truncated spherical shape completed by a cylindrical portion 21b defined by a cylindrical surface 24 provided on the lower half part 9. In the example shown, the cylindrical surface 24 is thus provided between the groove 23 and the strip 12. On one side its ends are the longitudinal edges of the body 16.
It is coplanar with 16a and on the other side this part 24
Is joined above to a step 35 to which the flexible foot 13 extends. The foot 13 can allow some angular misalignment with the lower end 16b of the body 16 which defines a groove 23 on its side.

The grooves 22,23 are widened or chamfered to facilitate the introduction of the sphere 11 into the housing 21a when the two half blocks 8,9 are assembled. Therefore the actual groove
22 extends outward due to the bifurcated edge or bevel.

In order to allow the block 7 to make a sliding movement inside the part 5, the upper side of the half block 8 has a longitudinal groove 26 into which a corresponding longitudinal flange 27 of the part 5 can engage. Furthermore, the lower part 5a of the part 5 is U-shaped or V-shaped for receiving the male mating end 28 of the half block 9.

Furthermore, a longitudinal opening 29 is provided between the strip 12 during the assembly of the block 7 in the first stable locking position inside the part 5.
Is cut into the portion 5 so that it can cooperate with the end portion 12a of the. The opening 29 is actually provided to receive the end portion 12a when the strip 12 is separated from the lateral passage by the pin 14 introduced into the recess 17, as will be explained below.

In a more general manner, the surface 24 of the half block 9 is shaped to be complementary to the surface formed on the half block 8 for receiving the end piece of the arm 4,
This end piece can be a sphere 11 or any other suitable element.

The end claw 13a is located at one end of the half block 9,
It is removable from the lug 15 by hand, which lug 15 allows the two half blocks 8, 9 to be unlocked and separated if necessary.

In order to allow the lower half block 9 to slide in the upper half block 8, the height of the half block 9 except for its forming portion 28 is such that the shoulder 20 in the longitudinal direction and the small rod 30. Is equal to the gap h ₂ provided in the half block 8. This rod is at right angles to two flanges 31, which define a groove 22 and are provided with a shoulder 20 on its inner surface. When the pin 14 is introduced into the recess 17, the half block 9 is thus retained in the half block 8 between this rod 30 and the guide shoulder 20.

The assembly of the above-mentioned connecting device during operation is as follows.

First of all, the half blocks 8 and 9 are mounted together by introducing the half blocks 9 into a gap of height half ₂ of the half blocks 8. To do this, the lower half block 9 is introduced into the recess 17 and the length of the strip 12 until the pin 14 is locked in place between the stoppers 18 and 19. It is arranged to slide. The two half blocks 8, 9 are then in their first stable locked state, the so-called "assembled" position (fourth).
Figure).

The block 7 is then manually introduced into the part 5 by fitting the lower edge 28 into the base 5a and introducing the flange 27 into the groove 26, whereby the strip 12 is positioned opposite the opening 29. Can be done. During this sliding movement, the protruding end portion 12a of the strip 12 first slides along the wall of the portion 5 and then the strip 12
Is introduced into the opening 29 by the elastic loosening of (5th,
(Fig. 6). In this assembled position, the freedom of movement of the block 7 in the part 5 is limited by reaching the stopper of the end part 12a at one or the other end of the opening 29. In this position, the claw 13a is also pin 1 by the gap d.
It should be noted that it is separated from 5.

The arm 4 of the window lifter is in the assembled position, its parts 5 and 6 are mounted and the block 7 is lowered to the sphere 11. The robot actuates the arm 4 and first moves the end portion 12a against one of the ends of the opening 29
Move it to one stopper (Fig. 6). From this moment on, the lower half block 9 is immobilized, whereas the sphere 11 continues to move the half block 8. As a result, in each block 7, the pin 14 is disengaged from the stoppers 18 and 19 and slides the length of the strip 12 so that as soon as these pins pass the end portion 12a of the strip 12, the strip 12 has its pawl 13a pin 15a. At the same time as being clamped on the top, it is elastically folded back inside the part 5 (FIG. 7).

In this second position, the half block 9 is then locked on the half block 8 by means of the pin 14 and the projection 15, and after the relative displacement of the two half blocks 8,9 the grooves 22,23 are no longer present. The spheres 11 are no longer positioned opposite each other and the spheres 11 are enclosed in their housings 21a, 21b. In this position, the end piece 11 of the arm 4 is locked in the block 7, which is free to slide in the part 5 and is in the position for use.

Therefore, when the two half blocks 8, 9 are mounted together and introduced into the part 5, the windowpane 2 is lowered to the end piece 11 of the arm 4 and then the half blocks 8, 9 are used. Arm of window lifter to lock in position 4
Need only be activated.

If at some later time it turns out that it is necessary to remove block 7 for whatever reason, the operator will need to use a slight half block to remove foot 13 from its pin 14. Claw 13a protruding above 8
It is necessary to remove this block 7 by applying a longitudinal pulling force to the half block 9 which at the same time frees the sphere 11 in order to separate its end from the manually lifted half block 8. Only.

As a variant, the stopper 18 of the strip 12 can be eliminated, so that the half block 9 is locked relative to the half block 8 in only one direction. Further, although the operation from the first stable lock position to the second lock position can be easily performed, this modification naturally has less advantages than the one having the two stoppers 18 and 19.

Furthermore, the cylindrical portion 21b is in the direction of the end portion 12a,
If possible, it can extend up to the end 12a and / or up to the finger 40. The relative movement position between the transverse and longitudinal block 7 of the part 5 and the sphere 11 is limited by the groove 23 and the bifurcated edge 25 together with the beveled surface of the base 5a of the part 5. Transverse movement is compensated for due to the slight deformation of the window lifter.

The opening 29 further allows longitudinal displacement of the half block 8 when the sphere 11 comes into contact with one of the edges 25.

In the embodiment shown in FIGS. 9 to 13, the block 7a is constituted by two half blocks 8a, 9a. The half block 9a is completely contained within the half block 8a and can slide inside it like a drawer. The half block 8a which receives this sliding body 9a is also on the joint 5a, 27 of the forming rail 5 all guide means 26,
28,30 are provided.

Preferably, the elastic locking elements 12, 13 are provided on the half block or slide 9a. Furthermore, it is noted that in this example the stopper 18 is eliminated and the stopper 19 is provided on the wall of the recess 17 opposite the strip 12. Other parts of the block 7a that are similar to the part of the block 7 are indicated by the same reference numerals. As in the previous embodiment, the assembly of half block 9a in half block 8a has its surface
The housing 21a is resealed by 24 and the assembly of the block 7a in part 5 is otherwise the same.

This variant guarantees a better guidance in the part 5 of the block 7a, since all the guiding surfaces belong to the same half block 8a instead of the block 7.
