Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The subject of the invention is a connection block between a window pane and a window lifting mechanism with a swinging arm in a motor vehicle, and a bottom part of the window glass associated with this block. and a device including a portion of the device.

[Conventional technology]

This device is of the type that includes a block for each arm that is articulated on the end piece of this arm and is slidable in a part that is rigidly attached to the bottom of the window pane.

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

Until now, these connections have been made manually, partially blind, on the car assembly line. Positioning these devices is therefore relatively tedious and cumbersome.

[Problem to be solved by the invention]

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

[Means to solve the problem]

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

Once the two half-blocks have been assembled and introduced into the corresponding parts of the bottom of the window pane, this block is inserted into the end piece of the arm of the window lifter in a suitable housing provided for this block. It will be appreciated that it is only necessary to lower the window pane so that it abuts the window.

It is then only necessary to robotically control the arm of the window lifter 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 much shorter time than the manual assembly used up to now.

According to another feature of the invention: - the means for locking the two half-blocks include cooperating stop elements (
includes an elastic element that can be clamped onto the protrusion.

- one of these elastic elements is a flexible longitudinal strip on one of the half-blocks and defines with the body of this half-block a recess, which recess is rigidly attached to the other half-block; The strip may be adapted to receive stopper pins, and the strip may divide the transverse passageway, and the locking stops may be provided on the strip or on the wall of the body, between which the stopper pin may be located. This is intended to lock the two half-blocks in their first stable position.

One strip is provided with a laterally projecting end portion.

The second elastic element is a flexible arm of one half-block provided with an end mold that can be clamped onto a corresponding projection of the other half-block, these elements together with the strip and cooperating pin Its size and location are such that the pawl does not engage the protrusion when the pin is pushed between the end stops, and the pin does not engage after one half-block slides relative to the other half-block). The pawl is sized and positioned so that the pawl does not come into contact with the protrusion when the strip is completely removed from the lateral passageway and returned to its resting position by elastic relaxation of the lateral passage.

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

〔Example〕

In FIG. 1, a motor vehicle door 1 is seen fitted with a window pane 2 and a window lifting mechanism 3 having two swinging arms 4 on a support housing. The end pieces of the arm 4 are hinged to blocks, and these blocks are attached to the window pane 2.
can be slid in a part 5 which is fixed to a U-shaped part 6 which receives the bottom of the pane, the two parts 5 and 6 being rigidly attached to this pane 2. The end piece 11 of the arm 4 that slides within the block may be a ball (ball joint) or any other suitable mechanism.

The invention aims at providing a connection between the part 5 at the bottom of the window pane and the arm 4 by means of a blocking device 7 shown in FIGS. 2 to 8, each hinged on an end piece 11 of the arm 4. shall be.

Each block 7 is made up of two half-blocks 8 and 9, one slidable relative to the other. For convenience of description, this half-block 8 will hereinafter be referred to as the "upper half-block" and the half-block 9 will be referred to as the "lower half-block", since this is the case when these half-blocks are attached to the section 5. This is because they are actually located in the relevant positions. The half-blocks 8 and 9 are further fitted with means for locking them together in two respective stable positions, these two positions being before the end piece 11 of the arm 4 is introduced into the block 7.
a first so-called "assembly" position in which the freedom of movement relative to the part 5 of the block 7 is restricted and the end piece 11 to the block 7;
The upper half block 8 is introduced into the lower half block 9
2, and a second so-called "use" position after being displaced by the end piece 11. Indeed, in this position the end sphere 11 is locked into the block 7 which can slide freely inside the part 5.

These means for locking the two half-blocks 8, 9 are attached to the opposite ends of these half-blocks,
It includes elastic and flexible elements 12, 13 capable of clamping the cooperating stop elements 14 and 15. In this example, the elastic elements 12 and 13 belong to the lower half-block 9 and can be an integral part of this half-block or additions can be added thereto) and also the elements 14 and 15.
is a part of the upper half block 8. The elastic element 12 is
It is a flexible longitudinal strip provided with an end portion 12a projecting a transverse passageway and forming an elbow-shaped member substantially perpendicular to the remainder thereof. The strip 12, together with the longitudinal fingers 40 of the body 16 of the half-block 9, defines an enlarged recess 17 in which the pin 14 can be received; The lateral passages are separated under pressure. Two notches or stops 18 , 19 for the pin 14 are provided on the sides of the strip 12 delimiting the recess 17 . The pin is actually arranged between stops 18 and 19, which hold the upper half-block 8 in its first locked stable position relative to the half-block 9. The first stop 18 is rounded to allow the pin 14 to pass therethrough, while the second stop 19 is notched to prevent further advancement of the pin 14.

The second elastic element 13 has an end mold 13a having a groove 13b.
It has flexible legs attached to it. In its normal position, where it is held elastically, the claw 13a of the foot 13 is in the groove 1
It is clamped by the corresponding protrusion 15 engaged with 3b.

The strip 12, the foot 13, the pin 14 and the protrusion 15 prevent the pawl 13a from engaging the protrusion 15 and the half block 8 against the half block 9 when the pin 14 is locked between the stoppers 18 and 19. After sliding, when the pin 14 is completely removed from the strip 12, the pawl 13a engages with the protrusion 15, and the strip 12 returns to its rest position (
It is placed in a position and dimensioned such that it returns to Figure 7).

The housings 21a and 21b are two half blocks 8°9
are provided to receive the end pieces of the arm 4, and the end pieces 11 are connected to the housing 21a.

Transverse grooves 22, 23 are provided in the blocks 8 and 9, respectively, for introduction into the blocks 21b. Since the end piece 11 described in this example is spherical, the housing 21a provided in the center of the half block 8 is defined by a cylindrical surface 24 provided on the lower half part 9. It has a corresponding truncated spherical shape completed by the cylindrical portion 21b. In the example shown, the cylindrical surface 24 is therefore provided between the groove 23 and the strip 12. On one side its end is located at the longitudinal edge 16 of the body 16.
a and on the other side this part 24
is joined above to a step 35 into which the flexible foot 13 extends. This foot 13 may allow some angular misalignment with respect to the lower end 16b of the body 16 defining the groove 23 on its side.

The grooves 22.23 are widened or beveled to facilitate the introduction of the sphere 11 into the housing 21a when the two half-blocks 8.9 are assembled. The actual groove 22 therefore extends outwards by a branched edge or slope.

In order to allow the block 7 to slide inside the section 5, the upper surface of the half block 8 is connected to the corresponding longitudinal direction of the section 5.
It has a longitudinal groove 26 in which a directional flange 27 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.
It is shaped like a letter.

Furthermore, the longitudinal opening 29 is such that it can cooperate with the end section 12a of the IJ knob 12 during assembly of the block 7 inside the section 5 in the first stable locking position.
It is provided by cutting into part 5.

The opening 29 is in fact provided to receive the end portion 12a when the strip 12 is separated from the transverse passages by the pin 14 introduced into the recess 17, as will be explained below.

Furthermore - in a boat fishing method, 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.

Further, the end claw 13a is located at one end of the half block 9,
It can be removed by hand from the protrusion 15,
This projection 15 makes it possible to unlock and separate the two half-blocks 8.9 if necessary.

In order to be able to slide the lower half-block 9 into the upper half-block 8, the height of the half-block 9, excluding its forming part 28, is equal to the longitudinal shoulder 20 and the small rod 30.
It is equal to the gap h2 provided in the half block 8 between. This bar is perpendicular to two flanges 31 which define a groove 22 and which are provided with shoulders 20 on their inner sides.

When the pin 14 is introduced into the recess 17, the half-block 9 is thus held in the half-block 8 between this small rod 30 and the guide shoulder 20.

The assembly of the above coupling device during operation is as follows.

First of all, half blocks 8 and 9 are mounted together by introducing half block 9 into the gap at height h2 of half block 8. To do this, the lower half-block 9 is inserted into the recess 17 and along the length of the strip 12 until the pin 14 is locked in place between the stops 18 and 19. Arranged to slide. The two half-blocks 8.9 are then in their first stable locked state, the so-called "assembly" position (FIG. 4).

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, so that the strip 12 is placed opposite the opening 29. You can make it happen. During this sliding movement, the protruding end portion 12a of the strip 12 first slides along the wall of the portion 5 and is then introduced into the opening 29 by the elastic loosening of the strip 12 (5th and 6th positions). figure). In this assembled position, the freedom of movement of the block 7 in the part 5 is limited by reaching the collar of the end part 12a at one or the other of the ends of the opening 29. It should be noted that in this position also the pawl 13a is separated from the pin 15 by a gap d.

The arm 4 of the window lifter is in the assembled position, with its parts 5 and 6 attached, and the block 7 has been lowered to the sphere 11. The robot actuates the arm 4 so as to first move the end portion 12a against one of the ends of the opening 29 to a stop (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 connected to the stopper 18.
9 and slid down the length of the strip 12, as soon as these pins pass the end portion 12a of the strip 12, the strip 12 snaps inside the portion 5 at the same time as the pawl 13a is clamped onto the pin 15. It is folded back elastically (Figure 7).

In this second position, the half-block 9 is then locked onto the half-block 8 by the pin 14 and the projection 15, and after the relative displacement of the two half-blocks 8, 9 the groove 2
2.23 are no longer located opposite each other and sphere 1
1 is confined within its housing 21a, 21b. In this position, the end piece 11 of the arm 4 is locked into the block 7, which is free to slide within the part 5 and is in position for use.

Thus, once the two half-blocks 8.9 have been fitted together and introduced into the part 5, the pane 2 is lowered to the end piece 11 of the arm 4 and then the half-blocks 8.9 are lowered.
It is only necessary to actuate the arm 4 of the window lifter to lock 9 in the position in use.

If later, for whatever reason, block 7
Even if it turns out that it is necessary to remove the half-block 8, the operator has no problem with the claw 1 protruding slightly above the half-block 8 in order to remove the foot 13 from its pin 14.
It is necessary to remove this block 7 by manually lifting the end of 3a and applying a longitudinal pulling force on the half-block 9, which at the same time frees the sphere 11 in order to separate it from the half-block 8. It just becomes.

As one modification, S) Stopper 18 of IJ knob 12
can be removed, so that the half-block 9 is locked in only one direction relative to the half-block 8.

Furthermore, although the operation from the first stable locking position to the second locking position can be carried out easily, this variant naturally offers fewer advantages than with two stops 18,19.

Furthermore, the cylindrical portion 21b extends in the direction of the end portion 12a, possibly up to the end portion 12a and/or towards the finger 40.
It can be extended up to. The position of relative movement between the block 7 and the sphere 11 in the transverse and longitudinal direction of the part 5 is determined by the slope of the base 5a of the part 5 as well as by the groove 23 and the branching edge 2.
Limited for 5. Transverse movements are compensated for slight deformations of the window lifter.

The aperture 29 further allows a 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 two half-blocks 3a.

9a. The half-block 9a is completely housed within the half-block 8a and can be slid inside thereof like a drawer.

The half-block 8a receiving this slide 9a is also provided with all guide means 26, 28, 30 on the joint parts 5a, 27 of the forming rail 5.

Preferably, the elastic locking element 12.13 is provided on the half-block or slide 9a. Furthermore, in this example, stopper 18 is eliminated and stopper 19 is replaced by strip 1.
It is noted that in the wall of the recess 17 opposite to 2. Other parts of block 7a that are similar to parts of block 70 are designated with the same reference numerals. In keeping with the previous embodiment, half block 9a in half block 8a
The assembly of block 7a in part 5 is otherwise similar, with its surface 24 resealing housing 21a.

This variant ensures better guidance within the part 5 of the block 7a, since all the guiding surfaces belong to the same half-block 8a and not to the block 7.
