Definitions

  • Window-lift in particular for motor vehicles.
  • the present invention relates to window-lifters in particular for motor vehicles, of the type comprising an ice support sliding essentially in rectilinear translation, guide members and actuating members of this support.
  • the object of the invention is to provide a particularly reliable, simple, light, space-saving window lifter which is endowed with good efficiency.
  • the subject of the invention is a window lifter of the aforementioned type, characterized in that the actuating members comprise a U-shaped rack which is articulated in the region of the top of the U on said support by a pin, a motor pinion with fixed axis engaged with the rack, and a fixed pivot received in a longitudinal groove of this rack.
  • the teeth of the rack have two rectilinear and parallel parts connected by a semicircle, the spindle passing through the center of this semicircle and the axes of the pivot and the semicircle being confused when the pinion attacks this semicircle.
  • the rack carries a semi-circular member which is superimposed on its semi-circular part.
  • circular has the same useful circumference and cooperates without sliding with a rolling track D t parallel to the direction of movement of said support and integral with this, the pin of articulation of the rack on this support passing through a slot of this last parallel to the runway.
  • the pivot is offset laterally, on the side opposite the pinion, relative to the trajectory of the spindle, the toothing of the rack Comprising two branches with small curvature, arranged on either side of the groove, and a crown region, with strong curvature, connected to the two branches and adjacent to the joint.
  • the rack is forced, under the action of the drive pinion, to simultaneously undergo a continuous movement of translation, ensuring the stroke lifting or lowering the ice, and a movement, also continuous, of rotation, during which the slide undergoes a reversal, which allows a small footprint for the entire mechanism.
  • the set of teeth is in fact defined by a continuous primitive curve which is none other than the envelope of the primitive circle of the driving pinion in its relative movement with respect to the rack.
  • This curve can be obtained either by a geometrical trace, or point by point starting from parametric Cartesian coordinates, established by taking for axes of coordinates the longitudinal axis of symmetry of the rack and an axis perpendicular to the previous passing through the center of l articulation of this rack on the glass support, the parameter being the distance which separates from the center of the joint the axis perpendicular to the direction of translation, passing through the center of the drive pinion and through the center of the guide pivot.
  • the movement described by the glass support is not strictly uniform, but the variation in the translation speed for a uniform speed of the drive pinion can be made less than 15%, which is entirely satisfactory from the makes this variation progressive.
  • the two embodiments described above make it possible to provide a large number of teeth on the rack for a given stroke of the glass. It follows that the motor pinion can be given a higher number of teeth, which makes it possible to reduce the load on each tooth while obtaining a better meshing. The engine torque can therefore be relatively low, which is a source of savings in the case of an electric motor drive.
  • the guide means of the ice support can be constituted in a conventional manner, by a cursor which is fixed or formed on the ice support and which slides along a fixed rail.
  • the assembly then comprises two driving pinions and two racks whose joints are spaced from one another on the support, which can then be constituted by a simple bar. As in the case of window regulators with divergent arms, equal forces are therefore applied to the window support at two symmetrically arranged points.
  • the window lifter shown in Fig.1 has three elements fixed to a door panel 1 of a motor vehicle provided with two vertical window slides (not shown): a guide rail 2, an electric motor 3 and a pivot 4. It further comprises a glass-carrying cursor 5 guided along the rail 2, and a rack 6 for actuating the cursor.
  • the rail 2 is vertical and is constituted by an L-shaped section, one branch 28 of which is parallel to the panel 1 but spaced from the latter, its fixing ⁇ being done for example by means of two end wedges 2 c , one of which only is shown.
  • the other branch 2b of the L, perpendicular to the branch 2a, is directed on the side opposite to the panel 1 relative to the latter.
  • the motor 3 is provided with a speed reducer 7 whose outlet axis 8 is perpendicular to the door panel 1 o On this axis is wedged a drive pinion 9 which can rotate in both directions.
  • the pivot_4 is cylindrical; the straight line D 1 which joins its center to the center of the pinion 9 is perpendicular to the rail 2 in the middle.
  • the slider 5 has two flat end portions 10 and 11 located in the same plane and pierced with openings 12 for fixing thereon a bottom of glass (not shown).
  • the part 10 of the cursor carries, on its face facing the door panel 1, pads 13 overlapping the branch 2 b of the rail 2 in order to guide the cursor along this rail. In service, the cursor is held parallel to the panel 1 by the bottom of the window due to the guidance of the edges of the window, of which the latter is secured behind the scenes of the vehicle door.
  • the parts 10 and 11 of the cursor are joined by an intermediate U-shaped part consisting of two opposite recesses 14, 15 perpendicular to the door panel and a part 16, parallel to the latter, forming rack support.
  • the spacing between the support 16 and the door panel is at most equal to that existing between the latter and the branch 2a of the rail 2.
  • the rack 6 comprises a first part 17 constituted by a rectilinear profile whose section is in ⁇ and comprises two parallel branches which are turned towards the door panel and have as spacing the diameter of the pivot 4. Each of these branches is connected to its end with a toothed rim 18 directed outwards and parallel to the panel 1.
  • the remainder 19 of the rack 6 is constituted by a half-cylinder 20 whose internal diameter and height are respectively equal to the internal width and to the height of the ⁇ 17; this half-cylinder is open towards the bottom of door 1 and has, at this end, a toothed flat edge 21 in the form of a half-crown of the same width as the edges 18.
  • the parts 17 and 19 of the rack are joined, which gives it a continuous toothing 22 in U and a blind longitudinal recess 23.
  • the parts 17 and 19 have been separated only for the convenience of the description, but the rack is in one piece.
  • the rack can thus pivot freely relative to the cursor 5, parallel to it, due to the permanent contact between the bottom of the recess 23 and the part 16 of the cursor.
  • the straight line D 2 joining the centers of the pivot 4 and of the spindle 24 when the pinion 9 attacks a rectilinear part of the toothing 22 is parallel to the rail 2.
  • the motor 3 is started so as to rotate the pinion 9 in the direction f 1.
  • the rack 6, guided by the pivot 4, rises by driving up the slider 5, and therefore also the ice, along the rail 2.
  • the movement of the cursor down is carried out in the same way.
  • the window regulator in Fig. 2 is essentially identical to that in Fig. 1, except that the pin 24 no longer passes through a circular hole in the part 16 of the slider, but through a slot 25 parallel to the rail 2 and the length of which is equal to, or alternatively, greater than the useful development of the toothed semicircle of the rack increased by the diameter of the spindle 24. Furthermore, the latter serves to fix a toothed sector 26 semi-to the rack circular which is superimposed exactly on the toothed semicircle of the rack. In the example shown, the part 16 of the cursor is located between this semicircle and the sector 26.
  • Any suitable means for example a flat (not shown) of the spindle 24, can be used to immobilize in rotation the sector 26 relative to the rack.
  • This sector 26 is in permanent engagement with a secondary rack 27 of useful length at least equal to the development of this sector which is fixed on the part 16 of the slider and extends parallel to the rail 2.
  • This window regulator generally works in the same way as that in Fig. 1. However, if we consider the upward travel of the cursor, when the pinion 9 attacks the semicircle of the rack and rotates it by 180 °, the sector 26 rotates at the same time around the same axis, which is the axis of the pivot 4, which moves the secondary rack 27, and therefore the cursor, at the same speed and in the same direction as when the pinion 9 meshed with the rectilinear part of the teeth 22. There is thus rolling without sliding of the sector 26 on the rack 27, and simultaneously relative movement of the spindle 24 from the upper end to the lower end of the slot 25. When the rack has rotated 180 °, it is pushed up as in the example in Fig. 1. Thus, the sector 26 takes over from the rack 6 between the two active phases thereof, and the speed of the cursor is uniformly continuous over the entire ascent or descent race.
  • the advantage of the window lifter in Fig. 2 is that, at the cost of a minor complication, the momentary stop of the cursor during the rotation of the rack is eliminated, which is more rational and faster and avoids a waste of energy.
  • the cursor travel is increased by the development of the toothed semicircle; for a given stroke, it is therefore possible to further reduce the length of the rack and therefore the size of the window lifter.
  • FIGs. 3 and 4 show a practical embodiment of a window lifter produced according to the principle of Fig. 2. The same elements are found there, which will therefore not be described again in detail.
  • a support plate 28 is provided which can be fixed by screws 29 to the door panel (not shown).
  • the plate On the side thereof, the plate carries the motor 3; the pinion 9 is received in a cylindrical casing 30 which projects on the other face of the plate and has a lateral light 31.
  • the central part 16 in relief of the cursor 5 is roughly parallelepipedic, and the secondary rack 27 is made of it.
  • the rack 6 differs from that of Fig.2 in that its longitudinal recess 23 is deeper at its blind end. At this point, a puncture 34 makes it possible to block in rotation a toothed wheel 35 playing the role of sector 26 of FIG. 2.
  • FIGS. 3 and 4 show the bottom of the glass 36 which carries the glass 37 to be maneuvered and of which two threaded rods 38 pass through the slots 12 of the cursor and are fixed by nuts 39.
  • Fig.4 clearly shows the relative arrangement of the various elements of the window regulator in the assembled state: the toothing 22 of the rack enters the window 31 of the casing 30 to mesh with the pinion 9, and its toothed edge is in contact with the rim 33 of the pivot 4.
  • the portion of greater thickness of the recess 23 of the rack allows the superposition of the head of the spindle 24 and of the pivot 4 during the 180 ° rotation of the rack.
  • the relief 16 of the cursor only serves to receive the other head of the spindle 24.
  • the arrangement of the rail 2 on the same side of the pivot 4 as the pinion 9 has the result that the rack rotates in the direction opposite to the rail; there is therefore no risk of it interfering with it, and there is no need to move the rack in a plane different from that of branch 2a of the rail.
  • the assembly can therefore be of lesser thickness, which is advantageous for its accommodation in the reduced space of a door bottom '.
  • the presence of the plate 28 makes it possible to obtain a compact assembly which is easy to place and to pack for transport and storage.
  • the pinion 9 can be actuated by a crank.
  • the guide rail must in practice be at least close to the center of gravity of the glass, and, to avoid risks of jamming of the cursor, the pivot 4 must be close to the rail. This limits the possible distance between the rail and the axis of the pinion 9.
  • the position of the crank must be close to the front of the door for the convenience of operation. It is then necessary to provide transmission members between this crank and the pinion 9, which complicates the window lifter.
  • these drawbacks do not exist with a motorized drive, since the motor 3 can be placed anywhere in the door panel. This is why the invention is particularly suitable for this case.
  • the window winders of the invention can easily be adapted to the case of doors and curved windows. It is sufficient to bend the rail 2 and the rack 6, which in no way impedes the movements and the pivoting of the latter. This pivoting can in particular be carried out then in the curve of the ice, there where the free space has the greatest thickness.
  • the window regulator in Figs. 3 and 4 is essentially metallic, the slider 5, the rack 6 and the plate 28 being made of stamped sheet metal.
  • the low operating torque that the pinion 9 must exert on the rack 6 opens the possibility of providing more economical teeth in plastic material, those of the two racks and of the pinion then having a greater thickness, which is possible without increasing the thickness of the assembly, as seen in Fig. 4.
  • this possibility makes it possible to envisage more precise helical teeth, because such teeth are too expensive to spare in metal parts.
  • the window lifter comprises an ice support constituted by a slider 41 slidably mounted on a fixed vertical rail 42 and on which is articulated by means of an axis 43 one end of a slide or rack 44 in the groove 46 which is engaged a guide pin, or pivot 47 which is fixed and whose center is located on a straight line D 1 which is perpendicular to the straight line D 2 representing the vertical trajectory of translation of the center 0 of the joint 43 backstage.
  • the straight line D 1 passes through the center of a pinion 48 which is rotated by an electric motor 49, and meshed with a toothing 51 formed on the slide 44.
  • the guide pin 47 is offset laterally on the side opposite the pinion 48 relative to the straight line D 2 , which is itself located outside the pitch circle A of radius R of the pinion 48, at a distance a from this circle.
  • the distance separating from D 2 the center W of the pin 47 is equal to d.
  • the primitive curve B of the toothing 51 of the slide must coincide with the envelope of the pitch circle A in the relative movement of the pinion 48 compared to the backstage.
  • This symmetrical curve relative to the straight line wo is defined in Cartesian coordinates, related to the axis Ox coinciding with the axis of symmetry of the slide and to the axis Oy perpendicular to the preceding by the following parametric equations: in which the parameter h is the distance which separates from the line D the center 0 of the joint 43 connecting the slide to the cursor.
  • the toothing 51 thus defined comprises two branches 52, 53 arranged on either side of the groove 46 and an apex region 54 which is connected to both branches. It is therefore a U-shaped curve or a hairpin.
  • the cursor 41 occupies its lower extreme position, corresponding to the full opening of the window and to the value -h m of the parameter h. From this position, the cursor 41 can move to the other extreme position, not shown, in principle symmetrical to the first, corresponding to the closing of the window and to the value + h m of the parameter, under the effect of l drive in a simultaneous movement of translation and rotation of the slide 44 due to the rotation of the pinion 48 meshing successively with the branch 52, the crown arc 54 and the branch 53 of the toothing 51.
  • the other end 46b of the groove is also closed, thus defining the end positions of the cursor.
  • the guide rail 42 is fixed at 56 and 57 to a curved door panel 58 and is itself slightly curved in the transverse plane of Fig. 9.
  • the slider 41 which slides along the rail by means of pads 59 are formed openings 61 for the passage of screws 62 ensuring the fixing of the glass bottom 63 on which is mounted a curved glass 64 which has a tight sliding contact with elements 66 provided at the upper end of the door bottom 67.
  • the rail 42 is, in the main plane of the door panel, located in line with the drive pinion 48 which is housed in a circular cavity 65 formed by stamping in a plate 68 secured to the face 67a of the bottom of the door and which also supports the guide pin 47, retained by a riyetage 47a, and the electric drive geared motor 49 (Fig.7 and 9).
  • the side of the cavity 65 is cut at 65a to allow passage of the slide toothing 51.
  • FIG. 7 corresponds to the mid-stroke position of the slide, for which the axis of symmetry of the latter coincides with the straight line D 1 , the cursor 41 then being superimposed on the plate 68.
  • the toothed slide 44 itself curved (Fig. 7), has an omega section (Fig. 8) whose sides 69 and the bottom 71 define the groove 46.
  • the toothing 51 is formed on the edge of the flat wings 72 , 73, of the profile in omega and on an arched area 74 connecting the wings to each other in the apex region.
  • a plate 76 which comprises a cylindrical part 78 forming a pad situated beyond the end 46a of the groove 46, and in which is engaged the hinge pin 43 fixed at one of its ends by a rivetàge 43a on a flat part 79 of the slider 41 formed in a puncture 80 of the latter, the cutting contour of which comprises a rectilinear part 80a and a circular part 80b.
  • the slider and the guide rail are deleted due to the autoguiding obtained thanks to the fact that the actuators are split and arranged symmetrically with respect to the axis XX which passes approximately through the center of gravity of the ice.
  • Two driving pinions 48 are provided, synchronized by the motor 49 and engaged with the toothed slides 44 which are articulated at 43 on the glass support constituted by a simple bar 81.
  • the geometry of a particular door may make it necessary to have a layout which deviates slightly from the rigorously symmetrical diagram of FIG. 10.
  • the assembly is such that the glass support is attacked at two spaced points under conditions which ensure that the glass moves without risk of jamming.
  • the window lifter is assumed to be used for controlling a window 80, flat or curved, the edges of which slide in parallel slides 82.
  • the quality of the guidance thus obtained is considered sufficient to again dispense with the slider and the rail, although the window lifter comprises, as in FIG. 6, a single driving pinion 48 and a single slide 44, the articulation of which 43 has a trajectory D 2 passing approximately through the center of gravity of the ice.
  • the glass holder is constituted by a fitting 84 to which the glass bottom 85 is fixed.
  • the slide is shown in its extreme high position. Intermediate positions are indicated in broken lines.
