WINDOW REGULATOR

  The present invention relates to window lifters for motor vehicles and more specifically window lifters.

  EP-B-0 208 237 discloses a slider consisting of side walls, one of which is elastically deformable and is provided with a cylindrical stud which penetrates into a hole in the glass. The rigidity of the wall keeps this stud in the hole in the glass. This slider allows a quick mounting of the glass on the slider compared to a mounting by screw / nut system. It also has an advantage over the windows glued to the sliders 10, because a stud slider allows easy replacement of the glass in the event of glass breakage, for example. On the other hand, in the case where the glass is glued to the door frame, for example by frost, or if the frictional forces of the glass with the seals become too great, for example due to the deformation of the door, the stud risk of coming out of the window hole if the user requests a descent of 15 windows.

  There is therefore a need for a slider which allows easy mounting of the glass on the slider and which maintains the glass-slider connection even in extreme conditions while retaining the possibility of dismantling the glass.

  Thus, the invention proposes a cursor comprising two walls forming jaw 20 and defining a window passage, a pad movable elastically with respect to the window passage and a means for blocking the stud with respect to the window passage.

  According to a variant, the cursor has a lock which maintains the locking means in a first position which allows the movement of the stud relative to the passage of glass.

  According to another variant, the cursor has a lock which maintains the blocking means in a second position which blocks the movement of the stud relative to the passage of glass.

  The stud may be located on one of the walls. One of the walls can be elastically deformable.

  According to another variant, the blocking means has an interlocking surface in the window passage.

  According to another variant, the locking means has an interlocking surface outside the window passage.

  The locking means may be movable in translation or in rotation relative to the cursor.

  The invention also provides a method of placing a window on a slider comprising the supply of a slider according to one of the preceding variants, the supply of a window pierced with a hole, the insertion of the window between the R: \ Brevets \ 19100 \ 19193.doc - 01/13/03 - 11:01 jaws until the stud penetrates the window hole and the locking means are actuated.

  According to a variant, the method comprises a step of mounting the cursor on a window regulator, before the step of driving in the window.

  According to another variant, the step of actuating the blocking means comprises a step of setting the window lifter in motion and a step of engaging the blocking means by passing the cursor to a particular position.

  According to a variant, the step of actuating the locking means is provided by the window.

  According to another variant, the step of actuating the blocking means is provided by a fixed stop relative to the cursor.

  According to a variant, the particular position corresponds to the lowest position of the window.

  According to another variant, the particular position corresponds to the highest position of the window.

  The invention provides a slider which comprises two walls, forming a jaw and defining a glass passage, a stud movable elastically relative to the glass passage 10 and a means of blocking the stud relative to the glass passage, this guarantees a blocking of the stud and avoiding possible separation of the cursor from the glass.

  Figure 1 shows a slider 10 on which is fixed a window 20 (Figure 2).

  This cursor comprises two walls 13 and 14 which form a jaw and define a window passage. These walls 13, 14 can be placed opposite or offset one with respect to the other this facilitating the release of the slider during its manufacture. An additional wall 26, connecting the two walls 13 and 14 by their bases forms the bottom of the jaw, this wall 26 serves to stiffen the slider 10 and 20 can also serve as a stop for the window 20 during the introduction of the latter in the slider 10. Additional walls 19 can be integrated into the slider on either side of the window passage in order to reinforce the maintenance of the glass 20 in the slider 10.

  The cursor 10 may also have a groove 16 which makes it possible to insert a cursor guide rail 25 in the case of a window regulator with rail.

  The cursor 10 may also have a notch 17 for introducing a grain of cable, this cable connected to a drive system will allow the cursor to go up and down. Of course, this slider is not limited to cable window regulators but can also be used in arm or rack window regulators, generally this slider 10 serves as a connection between a driving device and glass.

  The cursor also includes a pad 18 movable relative to the window passage. This stud 18 may be located on one of the walls 13, 14 defining the passage of the glass. In particular, one of the walls 13 can be elastically deformable in order to allow the passage of the glass, when it is put in place; advantageously the stud 18 35 will be installed on the elastic wall 13 to allow the stud 18 to be erased in front of the window when it is introduced into the jaw. This erasure of the stud 18 avoids the window 20 having to bypass it, thus avoiding shifting the bottom of the window in a direction perpendicular to its direction of introduction. Advantageously, the R: \ Patents \ 19100 \ 19193.doc- 13/01/03 11:01 surface of the stud which cooperates with the bottom of the window will have a bevelled shape in order to facilitate the spacing of the stud under the action of the bottom of window during the introduction of the window 20 into the slider 10. The stud 18 of generally cylindrical shape enters a hole 25 (Figure 2) of the window 20 in order to maintain it.

  The cursor also comprises a blocking means 11 of the block 18. This blocking means 18 prevents, after its installation, the movement of the block 18 relative to the passage of glass and makes it possible to firmly hold the block 18 in position in the hole 25 of the window 20. The locking means 18 makes it possible to increase the rigidity of the wall 13 which allows the stud 18 and the wall 13 to withstand the forces exerted by the window 20 on the slider.

  In the example of Figure 1 the locking means 11 has a latching surface 24 in the window passage. This locking means 11 can be a rod, preferably made of steel. This rod has a curved lower part, penetrating the glass passage and which serves as an interlocking surface 24 and an upper part 15 which serves as a support for the movable wall 13 in order to block it.

  The cursor 10 also includes slides 15 to guide the locking means 11, these slides 15 are U-shaped in which the locking means 11 is introduced.

  FIGS. 2 to 4 show the different stages of fitting the glass 20 into the slider 10 and the blocking of the elastic wall 13 by the blocking means 11.

  FIG. 2 shows the first phase of mounting the glass 20 on the slider 10. The glass 20 is mounted on the slider 10 by pushing the glass between the walls 13, 14 forming a jaw. Under the action of the bottom of the window 23, the stud 18, fixed on the elastic wall 13, moves aside to let the window pass. The window 20 is introduced until the stud 18 penetrates the window hole 25, the elastic wall 13 then returns to the initial position.

  FIG. 3 shows the phase of positioning the blocking means 11 in a position for blocking the movable wall 13 supporting the pad 18. Under the continuous action of the bottom of the window 23, the engagement surface 24 causes the blocking means 1 i in translation along the slides 15 and the upper part of the blocking means 11 is positioned behind the elastic wall 13 in order to prevent its displacement.

  During this blocking the window 20 is driven into a position which is lower than its normal position, shown in FIG. 4. The size of the window hole 25 and the dimension of the stud 18 are such that the movement of descent of the window during the blocking phase does not move the pad 18 and the elastic wall 13 from their position, thus the blocking means 11 is positioned correctly relative to the wall R: \ Patents \ 19100 \ 19193.doc - 13 / 01/03 - 1 1:01 elastic 13. In the example, the glass hole 25 will have a sufficient diameter to allow the glass 20 to move downwards without it coming into contact with the stud 18 .

  A pushing means 12 is integrated in the slider, this pushing means 5 generally made of rubber sinks under the action of the glass bottom 23 during the phase of fitting the blocking means 11, and returns to the normal position after the previous phase when the pressure required to set up the window 20 is released. The window 20 then rises until the window hole 25 abuts against the lower part of the pad 18. The window has a stable position because the thrust means 12 forces the window 20 against the pad 18. The window 20 being raised relative to the lowest position reached during its installation, the latching surface 24 is no longer in contact with the window 20, no force is exerted on the blocking means 11, the latter then remains in position.

  The slider of FIG. 1 can be delivered preassembled with the locking means 15 11, it must then be delivered in a non-locking position of the elastic wall 13.

  In order to keep the locking means 11 in this first position, a lock 21 is put in place.

  After the elastic wall 13 has been blocked by the blocking means 11, the latter will advantageously be stopped in translation to prevent the elastic wall 13 from being released. In order to maintain the locking means 11 in this second position, a lock 22 is put in place.

  In the example of FIG. 1, the two locks 21 and 22 are produced by housings produced in the slider and in which part of the locking means 11 is positioned. In the example, this is the start of the surface 24 24 which is locked by locks 21 and 22.

  The mounting is reversible, in fact the elastic wall 13 can be released. The locking means 11 is not in contact with the window 20, no force is exerted on the locking means 11, it can therefore be released from the lock 22 to be put back into the lock 21 thus releasing the elastic wall 13 The stud 18 can then be ejected from the window hole 25, thus making it possible to remove the window 20.

  The example shows a steel rod as a blocking means 11, but any material is usable, if it has sufficient resistance capacities and if the sliding function in the slides 15 and if the function of blocking by the locks 21 , 22 are met, in particular a plastic element can be used knowing that the blocking element 1 1 will certainly be more cumbersome to satisfy the conditions of rigidity, and more expensive than a steel rod, but it can be made of the same material as the slider 10 thus facilitating the recycling of the components.

  A: \ Brevels \ 19100 \ 19193.doc - 13/01/03 - 11:01 In the example of Figures 1 to 4, the pad 18 disappears when the glass 20 is inserted into the slider 10. The elastic wall 13, support of the stud 18, is blocked by the blocking means 11. The blocking means 11 is driven in translation by the bottom of the window 23. The locks 21 and 22 make it possible to maintain the blocking means 11 in position.

  The example in Figures 5 to 9 is similar to the previous example. Except with regard to the movement of the locking means 111 which is no longer driven in translation but in rotation from the bottom of the window 23.

  The locking means has a general shape of U, which pivots about the axis of rotation defined by the bottom of the U. The locking means 111 is provided with rotation studs 51 which are received in bores 53. The vertical arms of the U being walls, one of which blocks the elastic wall 13. The locking means 111 may be made of plastic.

  The locking means 111 comprises an interlocking surface 24 in the window passage, which may consist of an axis.

  When the glass 20 is introduced into the slider 110, the bottom of the glass 23 comes into contact with the engagement surface 24. For this contact to induce a rotation of the locking means 111, the engagement surface 24 must be offset from the plane passing through the rotation pads 51 and parallel to the direction 20 of introduction of the window. The latching surface 24 acts as a lever arm on the locking means 111 and drives it in rotation around the rotation pads 51.

  The window 20 is introduced into the window passage until the stud 18 penetrates the window hole 25 (FIG. 6), an additional pressure on the window 20 creates a force between the bottom of the window 23 and the surface of engagement 24 driving the locking means 111 in rotation (FIG. 8).

  A boss 54 produced in the stop means 111, is positioned in locks 121 and 122 produced in the slider 110, to maintain the blocking means 111 in the non-blocking position of the elastic wall 13 and to maintain the blocking means 111 in a blocking position of the elastic wall 13.

  The slider 110 also includes pushing means 112, which are integrated directly into the slider 110 in the form of wings which act as the pushing means 12 of the example of FIG. 1, and move the glass away from the bottom of the slider , thereby releasing the latching surface 24 from any pressure.

  Similarly, the glass 20 is dismantled by releasing the locking means 111 from the lock 122 and bringing it into the lock 121.

  In the case of FIG. 1, the pressure exerted by the window 20 may be due to an installer who exerts pressure on the top of the window. The pressure may also be due to an upward movement of the window regulator, and the arrival at the top stop of the window R: \ Brevets \ 19100 \ 19193.doc- 13/01/03 - 11:01 in the door frame, which acts as a fixed stop relative to the slider, creates the force necessary for locking. The use of the movement of the window regulator to lock the system makes it possible to overcome the force of the operator, in fact depending on the force exerted by the operator on the glass the system may not be locked.

  In the examples of the figures there 9, the steps for fitting the glass 20, for penetrating the stud 18 in the glass hole 25 and blocking the movable wall 13 by the locking means 11, 111 have been described so successive but it is obvious that these steps can be done at least partly simultaneously, according to the dimensions and tolerances of the different elements.

  In the examples of the figures there 9 the stud 18 disappears when the glass 20 is inserted into the slider 10. The elastic wall 13, support of the stud 18, is blocked by the locking means 11. The locking means 11 is driven in translation or in rotation by the bottom of the window 23. The latches 21 and 22 make it possible to keep the locking means 11 in position.

  The example in FIGS. 10 to 12 shows a system for blocking the elastic wall 13, in which the blocking means 211 does not have its engagement surface 224 in the window passage, but it is outside the window passage .

  FIG. 10 represents the cursor 210 which comprises inter alia a blocking means 211 which slides inside the cursor 210.

  We find the blocking positions of the blocking means 211, represented by the latches 221 and 222 which consist of a boss on the blocking means 211 and housings in the slider 210.

  After inserting the glass in the slider 210, according to FIG. 1, the positioning of the blocking means 211 can be done by the intervention of a manipulator 25 which engages the blocking means 211 in the slider 210. This phase of positioning the blocking means 211 can be done by setting the cursor in motion by the drive system. In the example of FIG. 12, the window regulator is driven in the direction of descent and the passage of the slider in a particular position engages the locking means 211. Advantageously, the particular position is the lowest position than the slider 210 can reach in normal operation. Indeed, a stop, fixed relative to the cursor, represented by the arrow 200, located on the window regulator or on a part of the vehicle body can be adapted to engage the blocking means 211 during contact of the stop 200 with the blocking means 211.

  The advantage of this embodiment is that the window 20 does not need to exert an additional force in order to engage the locking means 211, it is therefore not necessary to provide a clearance between the window hole 25 and the block 18, nor a R: \ Brevets \ 19100 \ 19193.doc - 01/13/03 - 1 1:01 pushing means 12 to raise the window to the normal position and hold it against the block 18, the clearance between the glass and the cursor is then reduced.

  Disassembly is done by removing the locking means 211, thus freeing the elastic wall 13.

  The example of FIGS. 13 to 15 differs from the previous example by the fact that the locking means 311 acts on the stud 18 itself and no longer on the wall 13 and by the fact that the window regulator must be put moving upwards so that the stop 200 fixed relative to the cursor acts on the locking means 311.

  The locking means 311 is placed on the slides 315 of the wall 14 10 (FIG. 14a).

  The locking means 311 must be positioned so as to be held by the wall 14, but it must not interact with the grooves 316 of the stud 18 to allow the latter to disappear when the glass 20 is introduced into the cursor (Figures 14b and 15b).

  The window regulator is then set in motion and the upper part of the locking means 211 comes into contact with the fixed stop 200, which has the consequence of driving the locking means 211 into the grooves 316 of the pad 18 (FIGS. 14c and 15c).

  The stud is then held and the window can no longer be removed accidentally.

  Similar to the other examples, the system is reversible to allow replacement of the glass.

  Locks can be put in place to maintain the locking means in the positions where the stud is free or to block.

  The latching principle has been described using the movement of the window regulator, but this can also be done by an operator manually.

  Of course, the present invention is not limited to the examples and embodiments described and shown, but it is susceptible of numerous variants accessible to those skilled in the art.

  For example, a cursor has been described with a stud integrated into the elastic wall 30, but one can imagine that the stud is integrated into the fixed wall.

  In all the examples, the blocking means is driven by a single movement of rotation or of translation, but it can be envisaged to combine a rotation and a translation, or to use a movement of rotation for the examples which show a movement of translation and vice versa.
