Definitions

  • the invention relates to a window lifting mechanism according to the preamble of claim 1.
  • the window lifting mechanism It is common to design the window lifting mechanism so that it raises or lowers the window across its entire width at the same speed. In the case of curved panes, it is a prerequisite that the handling in the area of the pane guides correspond, since otherwise the pane would tilt, especially if the pane lifting mechanism acts on two sides of the pane to support the pane guide. For the aforementioned reasons, one is bound to certain disk shapes if the disks are to be movable up and down in guides.
  • the invention has for its object to develop a generic disk lifting mechanism with simple means so that it can also be used to guide discs that have different lengths in the area of their guides, such as those e.g. with different radii, with a disc that is twisted in itself or with discs in which one of the guided sides is tilted inwards or outwards relative to the other side.
  • the pane lifting mechanism according to the invention can advantageously also be used for panes which are guided only in their lower region (frameless panes). There the problem of canting does not appear so strongly, even with very different developments, if the pane is guided on a short basis. However, by means of the pane lifting mechanism according to the invention, it can be achieved that the pane edge always remains in engagement with the seal on the surrounding body body and also always runs parallel to it.
  • the disk lifting mechanism comprises two toothed racks, which are assigned to the front and the rear area of the disk and have different modules and with which two pinions connected to the disk mesh.
  • This configuration which is chosen in particular if the window lifter is to be carried along, enables the desired different movement speeds of the front and rear window area to be achieved in a simple manner, namely only by means of racks provided with different modules. Instead of different modules, different sized pinions and the same racks can be used. Either . the rack and the pinion can be made inexpensively from plastic due to the low load occurring.
  • the pinions are mounted on the end regions of a crossbar provided with receptacles for the disk and a common drive device fastened to the crossbar is arranged between the pinions.
  • the crossbeam which can take over the leadership of a frameless disc, holds the disc, picks up the pinion and carries the drive contraption.
  • the entire window lifting mechanism and possibly also the window guide is designed except for the toothed racks on the crossbar, which means that the window lifting mechanism can be quickly installed and removed as a compact, preassembled assembly.
  • a P adjustment of the drive unit in the body - as is necessary with known window lifting mechanisms - is not necessary.
  • the fact that the drive device, for. B. an electric motor is fixed between the pinions on the crossmember and thereby does not change its position even when moving the disk up and down relative to the pinions, an inexpensive, rigid drive linkage can be used without joints.
  • pane lifting mechanism which is designed in accordance with the features of claim 2. This is made possible by turning away from the construction of known disk lifting mechanisms, namely that the threaded cable (which can be regarded as a toothed rack) or a toothed rack, as described, for example, in DE-OS 19 26 800, does not move and the driving pinion is arranged in a stationary manner, but that conversely the rack is fixed and the driving pinion is moved up and down.
  • the object on which the invention is based can be used in conjunction with a disk lifting mechanism with an approximately S-shaped guide tube, the outer legs of which do not run parallel to one another, with two drivers attached to a threaded cable, which reach through a slot in the guide tube and with an approximately perpendicular to the direction of movement the disc arranged and connected to this link guide, in which one of the drivers is guided, can also be advantageously solved in that the scenes guide with the first driver the area of the disc that should be movable at the lower speed. is assigned and the second driver is directly connected to the opposite region of the disc.
  • a corresponding disk lifting mechanism with two link guides is described for example in DE-OS 25 07 893. In a two-part pane, it causes an advance to occur when the pane is opened and a lag to the front part pane when it is closed.
  • a vehicle door 9 which is shown without external cladding, has two webs 11 and 13 produced as pressed sheet metal parts, on which toothed racks 15 and 17 are mounted with their toothing side facing outward.
  • the module of the rack 15 is made larger than the module of the rack 17, so that the longer development of the front region 19 of a movable pane 21 in the vehicle door 9 due to a greater curvature can be compensated for and the pane 21 does not tilt during its movement .
  • the disc 21 is attached to a crossbar 23.
  • Booms 25 and 27 are formed on the ends of the crossbeam 23 and accommodate pinions 29 and 31. These pinions are connected via a drive shaft 33 to an electric motor 35 to which a reduction gear 37 is flanged.
  • the pinion 29 and 31 are driven at the same speed by the common drive. Because the front rack, and thus also the associated pinion 29, has a larger module, the front arm 25, and thus also the front region 19 of the disk 21, is moved upwards or downwards faster than the rear region 39 the disc. The difference in speed is obsolete. Modules selected so that the longer distance which the front area 19 of the disk 21 has to travel due to the greater curvature is completely compensated for, thereby achieving a uniform, tilt-free movement of the disk 21.
  • the disc 21 is only guided at three points, two points being formed by the disc lifter (pinion 29 and 31).
  • the riding guide point is also connected to the bracket 23 and interacts with the rack 17.
  • Fig. 2 it is shown how the third guide point is designed concretely and how the attachment to the crossbar 23 takes place ... l
  • two guide parts 41 and 43 are provided, which are fastened with a screw 45 to a shoulder 47 of the crossbar 23 .
  • Each guide part 41 and 43 has a recess 49 and 51, through which the rack 17 is partially enclosed.
  • Fig. 2 it is also shown how the pinion 31 is attached to the arm 27 of the crossbar 23.
  • Two bearing parts 53 and 55 receive the pinion 31 provided with a slot 57 for connection to the drive shaft 33.
  • the bearing parts 53 and 55 like the guide parts 41 and 43, are provided with cutouts 59 and 61 for guidance on the rack 17.
  • a disk lifting mechanism with an S-shaped guide tube 63 in which a threaded cable 67 can be moved by a drive device 65.
  • Two drivers 71 and 73 fastened to the threaded cable 67 reach through a slot 69 in the guide tube 63.
  • the front driver 71 acts directly on a crossbar 77 carrying a disk 75.
  • the rear driver 73 is horizontal in an elongated hole 79 on an extension 81 of the crossbar 77 slidably mounted.
  • the elongated hole 79 enables the crossbar 77 and thus the disk 75 to be moved up and down, although the leg 83 of the guide tube 63 is arranged at an angle to the direction of movement of the disk 75.
  • the driver 73 assigned to this shank 83 moves slower relative to the direction of movement of the disk 75 than the front driver 71 acting in the direction of movement of the disk 75.
  • the resulting lower movement speed of the rear pane area which is obtained by multiplying by the cosine of the angle between the two legs 83 and 85 of the guide tube, compensates for the difference in length of the disk developments of the front (longer) and rear (shorter) pane areas.
  • FIG. 4 shows a further exemplary embodiment which essentially corresponds to that shown in FIG. 3.
  • a threaded cable can be moved by a common drive device 89.
  • a front and rear driver 93 or 95 attached to the threaded cable extends through a slot 91 in the guide tube 87. While the rear driver 95 acts directly on a crossbar 99 carrying a disk 97, the front driver 93 is horizontally displaceable in a link 101 in the crossbar 99.
  • the front leg 103 of the guide tube 87 has a slightly curved course, so that the driver 93 and as a result, the disc 97 in its front region is moved at changing speeds when moving up and down - despite uniform drive by the drive device 89.
  • the length difference of the windings of the disc in its front and rear area can not only -. As described in the exemplary embodiments for the sake of simplicity - restrict to one level, but also, such as if one leg of the guide tube is turned alone or additionally out of this level, also detect these differences.
  • the guide 88 and 90 are sections of concentric circles with the radii 92 and 94 respectively. This makes it possible, despite a strong inclined position of a middle post (not shown) adjoining the rear edge 96 of the pane, to make optimum use of the space in the vehicle door.
  • the reference numerals 88 'and 90' denote straight guides through which the same disk, in particular if it is designed as a flat or cylindrical disk, can be retracted in a straight line and therefore also without tilting.
  • a hatched area 98 indicates the larger space required for this, which makes it necessary for the door body to be guided much further forward than the pane in order to be able to link a lower door hinge.
  • FIG. 5 shows how the disk lifting mechanism is designed in the area of the rear driver 95 in detail.
  • the outer leg 103 of a Z-shaped bent sheet metal part 105 welded to the vehicle door forms a guideway for a guide element 107 to which the crossbar is fastened by a pin 109 and an adjusting screw 111.
  • the connection of the guide element 107 to the driver 95 is shown in FIG. 6.
  • the driver 95 is freely supported in the guide element 107, as a result of which tolerances in the installation of the guide tube 87 relative to the leg 103 of the leading sheet-metal pressed part 105 can be compensated for and thus a smooth operation of the Window lifting mechanism is possible.
  • FIG. 7 Another embodiment is shown in FIG. 7.
  • the pane 113 shown there can be moved in the vertical direction in the door body by means of a cable pull 115.
  • a cable pull 115 For this purpose, four deflection rollers 117, 119, 123 and 125 are mounted on the door body.
  • the cable pull 115 which is driven by a drive device 127, is placed around the deflection rollers in the form of a lying “8”. While the deflection rollers 119 and 125 assigned to the rear region of the disc 113 are arranged one above the other in the direction of movement, the deflection rollers 117 and 123 assigned to the front region of the disc 113 are at an angle to the direction of movement of the disc.
  • a longer development of the disc 113 in its front region can be compensated for by a lower speed in the direction of movement of the disc, and the disc can thereby be guided without tilting.
  • a link guide with an elongated hole 129 is formed on the bracket 121, in which a driver 5131 fastened to the cable pull 115 is displaceably guided.
  • a second rear driver 133 arranged on the opposite side of the cable pull 115 acts directly on the console 121 and thus on the disk 113.
  • FIG. 8 shows how the cable pull 115 acts on a guide element 135.
  • the cable 115 is connected to the guide element 135 by means of a press nipple which is not visible in the drawing.
  • the console shown in more detail in FIG. 5 can be attached to the guide element 135 in the same way.
