Description:
The invention relates to an adjustable carrier for connecting a window pane to a window lift of a motor vehicle. 
     The carrier is associated with the vehicle door through at least one guide track and consists basically of a base body and a holding body wherein the base body is guided on the guide track of the window lift and the window pane is clamped on the holding body. The holding body is able to swivel relative to the base body by means of a movable displacement means, and an articulated joint connection is provided between the base body and the holding body. 
     BACKGROUND OF THE INVENTION 
     From DE 44 35 008 A1 a solution is known for adjusting the window pane during the course of assembly. The preferably frameless window pane is held inside the door by guide tracks. The guide tracks are able to swivel in the transverse direction of the vehicle about a rotary axis which lies in the upper fixing point of the guide tracks. Adjustment is made by an adjusting device at the bottom end of the guide track. 
     The drawback with this solution is that the space in the lower region of the door is restricted, as a condition of the distance between the turning point and site of the adjusting device so that no great adjusting paths can be produced. Furthermore the entire installation area is affected, that is the adjusting path has to be taken into account when designing the whole door. 
     These drawbacks are overcome in DE-OS 28 43 634. The rotary axis of the swivel movement is here in the carrier. The carrier has a ball segment which corresponds with a corresponding bearing shell. A tension screw is mounted centrally in the bearing shell and in the ball segment and engages into the hole in the pane to interact with a tension plate. The adjustment and swivel movement is produced by swivelling the bearing shell. The position is fixed by tensioning with the tension screw. 
     Adjusting the window pane thus takes place freely within the area. That is, it is necessary to proceed stepwise by the trial and error method in order to reach the correct position. If the ideal position is not reached with the current adjustment step then the pane clamp has to be released. Thus the previous position becomes lost and the next adjustment step has to be introduced. As a condition of this setting principle an undesired vertical displacement takes place when adjusting the pane across the driving direction. 
     With another solution known from DE 93 07 599 U1 the window pane is fixed on a separate part connected for articulated movement to the base body of the carrier. Between this part and the carrier there is a vertically displaceable wedge so that it is possible to change the angular position of this part relative to the carrier and thus the position of the window pane relative to the vehicle body. The drawback here is that when the connection between the base body and holding body of the carrier becomes loose the connection between the holding body and window pane is also released at the same time. 
     From DE 35 45 856 C1 a carrier is known for a motor vehicle window lift which has a base plate guided between two guide rails and a holding rail connected to same through a ball joint for the purpose of holding a window pane. Adjusting the position of the holding rail relative to the base plate is carried out directly by means of a threaded bolt on the base plate which engages in a threaded bush of the holding rail. 
     SUMMARY OF THE INVENTION 
     The object of the invention is to provide a simple solution for swivelling the window pane about an axis lying substantially parallel to the driving direction and through which it becomes possible to position the window pane with precision against an associated sealing contour on the vehicle body. 
     According to one variation of the solution, the base body and the holding body of the carrier are connected together by an articulated joint and adjusting means for changing the position of the holding body relative to the base body are provided on the carrier and can be operated by means of a tool from outside of the carrier and window lift (by an operator or robot for example). These adjusting means act independently of the fastening means by which the window pane is fixed on the holding body of the carrier. The relative position of the holding body and base body can therefore be changed directly or indirectly by operating the adjusting means so that even when the fixing of the window pane is loosened later on this position remains set. 
     A displacement means in the form of a displaceable element (such as for example a sliding wedge) is thereby associated with the adjusting means and can be moved by the adjusting means in the direction of the articulated connection between the holding body and base body so that an indirect connection is provided here. In order to form contact faces between the displaceable element with the base body and/or the holding body a circular arc shaped curved cylinder surface with the same radius and same center point is provided both on the displaceable element and on the holding body or base body so that a complete surface contact is achieved during the course of displacement. This has the advantage of making displacement simple and uncomplicated. 
     Displacement is carried out by operating the adjusting means from outside, preferably through the crash guard strip of the vehicle body. As adjusting means are adjusting screws, threaded spindles, threaded bolts or the like. 
     A turning angle on the adjusting means is assigned to a precisely fixed displacement path on the top edge of the window pane so that adjustment can take rapidly and with precision. 
     In another basic variation of the solution the displaceable part consists of two segments of which each segment has a contact zone which is connected to an associated contact area on the base body and/or on the holding body and wherein the tangents at the contact faces, contact lines and/or contact points have different slopes. The position of the swivel axis of the window pane can thus be fixed through the variable slope of the tangents. 
     This solution has the advantage that the swivel movement of the window pane is not bound to the structural design of the articulated joint but can be fixed freely in space. The contact zones on the segments and the contact areas on the base body and/or holding body can be designed so that the window pane can be swivelled about any selected point in space.

     DETAILED DESCRIPTION OF THE INVENTION 
     The following co-ordinate system will be used for indicating the directions below: 
     x-axis: driving direction 
     y-axis: horizontal and transversely to the driving direction 
     z-axis: vertical and transversely to the driving direction 
     FIG. 1 shows the construction of a carrier. A base body  1 . 1  which is guided on a guide track (not shown here) of a window lift, is connected for articulated movement to a holding body  2 . 1 . 
     The articulated connection is produced through a cylinder-shaped guide member  30 . 1  which is associated with the base body  1 . 1  and which corresponds to a guide surface  31 . 1  formed on the holding body  2 . 1   
     In this area a full length through bore  32  is provided in the guide member  30 . 1  and a corresponding threaded bore  20  is provided in the holding body  2 . 1  into which a clamping screw  120  engages. 
     The holding body  2 . 1  is associated with a window pane (not shown here). This window pane is supported on window pane holders  21 . 1  and is connected to the holding body  2 . 1  through a window pane bolt (not shown here) which is guided through the window pane bolt bore  22 . 1 . A recess  10 . 1  is provided in the base body  1 . 1  in order to ensure there is sufficient space for the window pane bolt. 
     In the lower part of the carrier is an adjusting screw  50 , the head of which is embedded in a socket  23  mounted on the holding body  2 . 1  and engages in a threaded bore  11  of the base body  1 . 1 . 
     In order to adjust the slope of the window pane the adjusting screw  50  is turned and the distance between the base body  1 . 1  and holding body  2 . 1  is changed in defined manner. The guide face  31 . 1  thereby slides on the guide member  30 . 1  so that the holding body  2 . 1  is swivelled in the y-direction relative to the base body  1 . 1 . This movement takes place about a swivel axis  33 . 1  lying on the x-axis. The swivel axis  33 . 1  is not fixed but shifts with the movement. The position of the window pane is also displaced slightly on the z-axis. 
     The clamping screw  120  serves to fix the position of the holding body  2 . 1  relative to the base body  1  and thus to fix the slope of the window pane. 
     FIG. 2 describes another design. Here the articulated connection between the base body  1 . 2  and the holding body  2 . 2  is produced through an axis. designed as a clamping sleeve  34 . 1 . Bearing tabs  35 . 1  are formed on the holding body  2 . 2  and engage in corresponding openings  13 . 1  in the base body  1 . 2 . Bearing bores  36 . 1  in the bearing tabs  35 . 1  hold the clamping sleeve  34 . 1  which is mounted in the bores  14  of the base body  1 . 2 . Thus the holding body  2 . 2  can swivel about the swivel axis  33 . 2  relative to the base body  1 . 2 . 
     Adjustment is carried out through a threaded bolt  51  which engages on each side in steppe d bolts  52 . 1 ;  52 . 2 . The stepped bolt  52 . 1  is mounted in the base body  1 . 2  and the stepped bolt  52 . 2  is mounted in the holding body  2 . 2 , with these positions being fixed by plastics clips  53 . 1 ;  53 . 2 . 
     The slope of the window pane is adjusted by the rotary movement of the threaded bolt  51 . One revolution results in a definite change in the setting angle of the holding body  2 . 2  relative to the base body  1 . 2 . 
     The position is fixed by a separate screw (not shown here). The window pane is fixed in a similar way to the example explained with reference to FIG.  1 . 
     FIG. 3 shows a further embodiment of the invention. The holding body  2 . 3  is here designed in three parts for the purpose of providing a smooth clamp around the window pane, and consists of a socket plate  24 . 1 , an insert  25 . 1  and a holding plate  26 . 1 . The socket plate  24 . 1  is connected to the base body  1 . 3  similar to the embodiment described with reference to FIG.  2 . The socket plate  24 . 1  is adjoined by the insert  25 . 1  which surrounds the window pane. The socket plate  24 . 1  supports a collar  27  which engages in a hole in the window pane. 
     A fixing screw  28 . 1  provided for clamping the window pane engages through the socket plate  24 . 1 , through the insert  25 . 1  and through the holding plate  26 . 1  The fixing screw spreads out the collar  27  and thus fixes the position of the window pane. The articulated connection between the base body  1 . 3  and the holding body  2 . 3  is produced similar to the example described with reference to FIG.  2 . 
     A threaded bore  28 . 2  is formed in the holding plate  26 . 1  to hold the fixing screw  28 . 1  which engages into the threaded bore. By turning the fixing screw  28 . 1  the holding plate  26 . 1  is drawn against the socket plate  24 . 1  and thus the window pane becomes clamped. 
     Adjusting the slope of the window pane is carried out through an adjusting screw  54 . 1 . One side of the adjusting screw  54 . 1  engages in a threaded bore  15  which is formed on a projection  16  of the base plate  1 . 3 . The adjusting screw  54 . 1  has a collar  54 . 2  which bears against a projection  29  of the socket plate  24 . 1  through a rubber buffer  55  and in the installed position projects into the area of the holding plate  28 . 2 . By turning the adjusting screw  54 . 1  the collar  54 . 2  presses against the projection  29  so that the adjustment process can be produced in this way. 
     FIG. 4 shows a further design of the invention. The window pane  7  is clamped as in the embodiment according to FIG.  3  through an insert  25 . 2  between a socket plate  24 . 2  and a holding plate  26 . 2 . The socket plate  24 . 2  is connected for articulated movement with the base body  1 . 4  through a bolt  34 . 3 . 
     A threaded member  56  is mounted centrally in the base body  1 . 4  in a threaded bore  17 . A threaded spindle  57  runs through the threaded member  56  and through a bore in the holding body  2 . 4 . The ends of the threaded spindle  57  are assigned nuts  58 . 1 ,  58 . 2  wherein the nut  58 . 2  has a left-hand thread and the nut  58 . 1  has a right-hand thread. The threaded spindle  57  has in the region of the threaded member  56  a square edge  57 . 1  which engages in a correspondingly shaped contour of the threaded member  56 . 
     Adjusting the window pane  7  proceeds as follows: 
     One of the nuts  58 . 1 ,  58 . 2  is loosened. Then the spindle  57  is turned. The opposing nuts  58 . 1 ,  58 . 2  are thereby entrained. The rotary movement of the spindle  57  is determined by the square edge  57 . 1  on the threaded member  56 . This stands in engagement with the base body  1 . 4  through a thread. As a result of the rotation of the spindle  57 , the threaded member  56  is moved on the y-axis relative to the base body  1 . 4  and is pressed against the holding body  2 . 4  so that this is swivelled about the bolt  34 . 3 . 
     After the adjustment process the position is fixed by tensioning the nuts  58 . 1  or  58 . 2 . 
     A further embodiment is shown in FIG.  5 . The articulated connection between the holding body  2 . 5  and the base body  1 . 5  corresponds substantially to the embodiment as described with reference to FIG.  1 . 
     The displacement of the holding body  2 . 5  relative to the base  20  body  1 . 5  is carried out by a displaceable part, which is designed here as a sliding wedge  4 . 1 . The sliding wedge  4 . 1  is mounted between the holding body  2 . 5  and the base body  1 . 5 . The contact surface  18  associated with the base body  1 . 5  and the contact surface  40  associated with the sliding wedge  4 . 1  have ribs to enable a gripped contact between the base body  1 . 5  and the sliding wedge  4 . 1 . 
     Changing the position of the holding body  2 . 5  relative to the base body  1 . 5  is carried out by moving the sliding wedge  4 . 1  on the z-axis. 
     With the design illustrated in FIG. 5 a spline  41  is attached at the side of the sliding wedge  4 . 1  into which a pinion  511  engages as a part of an adjusting tool  510 . The adjusting tool  510  is mounted in a bore of a tab  19  formed on the base body  1 . 5 . 
     By turning the adjusting tool  510  the sliding wedge  4 . 1  can be moved on the z-axis and thus the slope of the holding body  2 . 5  relative to the base body  1 . 5  can be changed. 
     Fixing this position and fixing the window pane are carried out through a fixing screw  28 . 3  which engages through recesses (visible in FIG. 5 but not numbered) in the base body  1 . 5 , in the sliding wedge  4 . 1 , in the holding body  2 . 5  and in the window pane (not shown). This fixing screw  28 . 3  is assigned a nut (likewise not shown) so that the window pane can be clamped in the desired position. 
     The example illustrated in FIG. 6 corresponds in its design substantially to the example illustrated in FIG.  5 . The displacement of the sliding wedge  4 . 2  is here achieved through an adjusting bolt  43  mounted centrally in the holding body  2 . 6  in a bore  42 . This adjusting bolt  43  has a spline  43 . 1  which is connected to an internal spline  44 . 2  attached on one side in a recess  44 . 1  of the sliding wedge  4 . 2 . By turning the adjusting bolt  43  it is possible to move the sliding wedge  4 . 2  in the z-direction and thus to produce the desired position. 
     A fixing screw  28 . 4  engages in a threaded bore  43 . 2  of the adjusting bolt. The window pane can thus be tensioned in the desired position. 
     In an advantageous design of the contact surfaces between the sliding wedge  4 . 2  and the base body  1 . 6 , they are formed as circular arc shaped curved surfaces. The radii R, R′ of the circular arc shaped curved surfaces are approximately the same size and have a common center point (not shown here). This allows a contact bearing over the entire surface whatever the position of the sliding wedge  4 . 2  relative to the holding body  2 . 6 . 
     FIGS. 7 and 8 show a solution where the displacement is likewise carried out through a sliding wedge  4 . 3 . 
     The holding body  2 . 7  corresponds in its construction substantially to the example described with reference to FIG.  3 . The window pane (not shown here) is held in an insert  25 . 3  and is clamped through the socket plate  24 . 3  and the holding plate  26 . 3 . The holding body  2 . 7  is bound to the base body  1 . 7  through fingers  35 . 3  which are mounted in the upper part of the socket plate  24 . 3  and engage in corresponding recesses  13 . 2  in the base body  1 . 7 . 
     The sliding wedge  4 . 3  whose contact surfaces with the base body are formed as in the previous example as circular arc shaped curved surfaces, is mounted between the base body  1 . 7  and the socket plate  24 . 3 . A recess  44 . 3  is mounted centrally in the sliding wedge  4 . 3  and an eccentric  513  is mounted in the recess. The engagement in the eccentric  513  is formed as an internal hexagon  514  in which engages a bush  515  having a hexagonal outer contour. 
     This bush  515  is mounted with its hexagonal outer contour in positive engagement in an internal hexagon  451  of the adjustment bush  45 . This internal hexagon  451  continues as a threaded bore  453  wherein the adjustment bush  45  is provided in this region with an external hexagon  452 . A clamping screw  12  with screw head  12 . 4  is mounted inside the bush  515  and has a collar  12 . 3  which adjoins the base body  1 . 7 . The other end of the clamping screw is provided with an external engagement  12 . 1  which is formed for example as a torus or external hexagon. The shaft of the clamping screw  12  supports a thread  12 . 2  which engages with the thread  453  of the adjustment bush  45 . 
     In order to change the slope of the holding body  2 . 7  and thus the slope of the window it is necessary to proceed as follows: 
     The external hexagon  452  of the adjustment bush  45  is seized and turned by a suitable tool. The rotary movement is transferred through the internal hexagon  451  of the adjustment bush  45  to the bush  515  and thus to the eccentric  513 . This moves the sliding wedge  4 . 3  on the z-axis so that the position of the holding body  2 . 7  relative to the base body  1 . 7  is changed. 
     If this ideal position is reached then this position is fixed by seizing the clamping screw  12  round its external engagement  12 . 1  with a suitable tool and tensioning it relative to the adjustment bush  45 . The external hexagon  452  of the adjustment bush  45  is thereby held. 
     In FIG. 17 a solution is shown wherein a sliding wedge  4 . 6  is mounted between the base body  1 . 6 ′ and the holding body  2 . 6 ′. This sliding wedge is arranged so that its taper points in the x-direction. 
     As the sliding wedge  4 . 6  moves in the x-direction (direction of arrow), the contact surfaces  40 . 1 ;  40 . 2  of the sliding wedge slide on the associated contact surfaces  181  on the base body  1 . 6 ′ or on the contact surface  231  on the holding body  2 . 6 ′. 
     This results in the holding body  2 . 6 ′ swivelling relative to the base body  1 . 6 ′ about the articulated connection which can be seen in FIG. 17 but is not marked in any further detail. 
     In order to ensure the contact surfaces  181 ,  231  bear against each other over their entire surface area they are provided with a restriction which is not shown in the drawings. 
     The movement of the sliding wedge  4 . 6  is carried out by adjusting means as already described in the above examples. 
     A further variation of the solution is described in FIG. 9 in connection with FIG.  10 . Here the window pane  7  is held between a holding plate  26 . 4  and a displaceable part  4 . 4  wherein an insert  25 . 4  is provided between the holding plate  26 . 4  and the window pane  7 . This unit is tensioned with the base body  1 . 8 . The tensioning is produced through a fixing screw  28 . 5  which is screwed into the holding plate  26 . 4  and which runs through corresponding recesses (not shown in further detail in the drawings) to fix the window pane  7 . 
     The displaceable part  4 . 4  consists of two segments  4 . 4 ′,  4 . 4 ″ which are fixedly connected together. The segments  4 . 4 ′,  4 . 4 ″ have contact zones  46 . 1 ′;  46 . 1 ″ which are in connection with contact areas  47 . 1 ′,  47 . 1 ″ of the base body  1 . 8 . 
     In order to ensure the contact zones  46 . 1 ′,  46 . 1 ″ bear with their entire surface area against the contact regions  47 . 1 ′,  47 . 1 ″ during displacement, here both the contact zones  46 . 1 ′,  46 . 1 ″ and the contact regions  47 . 1 ′,  47 . 1 ″ associated with same are designed as circular arc shaped curved surface areas. The radius Rl of the upper segment  4 . 4 ′ is larger than the radius R 2  of the lower segment  4 . 4 ″ Both have a common center point M (see FIG.  10 ). 
     In order to change the position of the window pane  7  the displaceable part  4 . 4  is moved on the z-axis. The socket body  2 . 8  thereby moves with the window pane  7  about the center point M. 
     The center point M does not move during the adjustment process. The spot A marked in FIG. 10 is the spot where the perpendicular from the center point M to the surface of the window pane  7  includes a right angle with the tangent at this place. This spot A has as a result of displacement also a component of movement upwards (z-direction). Since the window pane is however only fixed after the adjustment process this can be corrected. Thus the window pane body swivels as shown in FIG. 10 noticeably about the point A during adjustment. 
     Through these geometrical features it is possible with suitable dimensions of the radii RI, R 2  to place at the spot A at any desired place. 
     The invention is however not restricted to the embodiment of the contact zones  46 . 1 ′,  46 . 1 ″ and the contact regions  47 . 1 ′,  47 . 1 ″ as circular arc shaped curved surfaces with the aforesaid design of radii. It is also possible to design these as any type of curved or any type of flat surfaces. However a contact bearing over the entire surface area is then not reached. The contact zones and/or contact regions shaped in this way have a linear contact, with this line wandering as the segments are displaced. 
     A solution of this kind is shown diagrammatically in FIG.  11 . The contact zones  46 . 2 ′,  46 . 2 ″ in the position shown in solid lines contact the contact regions  47 . 2 ′,  47 . 2 ″ at points P 1 , P 2 . The slopes of the tangents T 1 , T 2  at this point are different. The condition has to be fulfilled where the tangent T 2  with regard to the x-direction has a lesser slope than the tangent T 1 . The orthogonal of the tangents T 1 , T 2  meet at the momentary pole MP′ 
     When the displacement part  4 . 5  moves on the z-axis, the points P 1 , P 2  move about the momentary pole MP′. A further position of the displaceable part  4 . 5  is drawn in by dashed lines. It can be seen that the slope of the tangents T 1 ′, T 2 ′ alters in the new contact point P 1 ′, P 2 ′. A new momentary pole HP″ is thereby produced. It is clear that the momentary pole MP″ has thereby moved relative to the momentary pole MP′. Thus the designer has the possibility of fixing the movement of the momentary pole MP′, MP″ and thus the displacement path of the window pane  7  by configuring the path of the contact zones  46 . 2 ′,  46 . 2 ″ and the contact regions  47 . 2 ′,  47 . 2 ″. The shift in the window pane  7  in the z-direction which thereby occurs can be compensated prior to its final fixing in the ideal position. 
     The path of movement of the momentary pole shown in FIG. 11 represents the general case. As a special case the example applies as shown in FIGS. 9 and 10 since the momentary pole MP does not move through the configuration illustrated there of the radii R 1  and R 2 . 
     The displacement of the segments can take place by means such as those already described above. These include for example displacement by an adjustment pinion which engages in a spline provided at the side on the displaceable part (see FIG.  5 ). These means are not shown in FIGS. 9 to  11 . 
     A further embodiment of the invention is illustrated in FIGS. 12 to  16 . Also here the window pane  7  is held between a holding plate  26 . 5  and a displaceable part  4 . 5 . An insert  25 . 5  is provided between the holding plate  26 . 5  and the window pane  7 . This unit (holding plate  26 . 5 , insert  25 . 5 ) is tensioned with the base body  1 . 9 . The tensioning is produced through a fixing screw  28 . 6  which runs through corresponding recesses (not shown in further detail in the figures) and is screwed to the holding plate  26 . 5 . The window pane is thereby fixed in the ideal position. 
     The displaceable part  4 . 5  consists of two segments  4 . 5 ′and  4 . 5 ″ which are connected together through a flexible web  4 . 5 ′″. The segments  4 . 5 ′ and  4 . 5 ″ are designed as wedges lying on the x-axis and having different wedge angles α, β. The position of the segments with the wedge angles α, β can be seen from the sectional diagrams shown in FIGS. 13 and 14. The tapers of the wedges each point in the same direction. The segments  4 . 5 ′ and  4 . 5 ″ bear with their contact bearing faces  48 . 1 ′,  48 . 1 ′ against the window pane  7 . On the opposite side, the segments  4 . 5 ′,  4 . 5 ″ are provided with contact surfaces  47 . 3 ′,  47 . 3 ″ which adjoin contact zones  46 . 3 ′,  46 . 3 ″ of the base body  1 . 9 . 
     The contact surfaces  47 . 3 ′,  47 . 3 ″ and the contact zones  46 . 3 ′,  46 . 3 ″ are here designed flat. It is however also possible in a similar way to the preceding example to provide between them a linear or spot contact whose tangents at the contact point between the contact face  47 . 3 ′,  47 . 3 ″ and the contact zone  46 . 3  ′,  46 . 3 ″ point in the x-direction and have different slopes. 
     The method of operation of the carrier described above will be explained with reference to FIGS. 15 and 16. The displaceable part  4 . 5  is here shown in two different positions. With this illustration to show more clearly the geometric conditions the holding plate  26 . 5  including window pane  7  have not been drawn in. 
     A displacement on the x-axis results through the different wedge angle α, β, in a differing shift of the contact bearing faces  48 . 1 ′,  48 . 1 ″ in the y-direction, whereby the flexible web  4 . 5 ″ becomes deformed. Thus the window pane (not shown here) is turned about an axis lying on the x-axis so that a change in the position of the window pane and an exact contact bearing against the vehicle body can be achieved. 
     In order to obtain a bearing of the contact bearing faces  48 . 1 ′,  48 . 1 ″ against the window pane over their entire surface area, the contact faces  47 . 3 ′,  47 . 3 ″ and/or contact zones  46 . 3 ′,  45 . 3 ″ are provided with a restriction which is not shown in the figures. 
     The displaceable part  4 . 4 ,  4 . 5 ,  4 . 6  is reinforced by adjusting means as already described in the above examples. 
     In a further design of the invention it is proposed to connect the two segments together neither rigidly nor flexibly but to arrange them individually. The segments can then be displaced independently of each other through adjusting means whereby deliberately preset movement sequences can be produced. 
     Through this arrangement it is also possible to displace both segments in synchronization.
