Definitions

  • the invention relates to a cable window lifter according to the preamble of claim 1 and a driver for such a cable window lifter.
  • the maximum window lift of a window pane to be adjusted results from the length of the guide rail minus the overall height of a one-piece driver guided along the guide rail and connected to the window pane.
  • a cable window lifter in which a driver which is displaceably mounted on a guide rail is connected to a lifting rail to which the pull cable of a cable drive and the window pane to be adjusted are fastened.
  • the lifting rail is designed to be displaceable relative to the driver in the longitudinal direction of the guide rail. This arrangement increases the stroke of the window lifter without increasing its installation height.
  • this known cable window lifter does not allow a pane lift that goes beyond the distance between the cable deflections provided at the ends of the guide rail.
  • An increase in the disc stroke does not require an extension of the guide rail, but the maximum disc stroke remains limited by the distance between the cable deflections, so that the height of the required installation space cannot be reduced.
  • This known cable window lifter is also expensive, complex to manufacture and relatively heavy due to the large number of individual parts.
  • a cable window lifter is known in which the cable section between the upper cable deflection and the driver and the cable section between the lower cable deflection and the driver on the driver crosswise are led. This enables a particularly large window lift stroke with a constant distance between the cable deflections. Accordingly, the distance of the cable deflections can be reduced with a constant stroke length.
  • the invention has for its object to provide a cable window lifter and a driver for a cable window lifter, which realize a disk stroke with simple assembly, which exceeds both the length of the guide rail and the distance of the cable deflections.
  • the invention enables a maximum disc stroke which covers both the distance of the guide rail and the distance between the Leadership roles. It is in the upper or lower end position of the base part on the guide rail by the cable force of the traction cable, the sliding part is displaced relative to the base part and parallel to the guide rail, so that the sliding part and a window pane connected to it are moved to a point which lies beyond the respective cable deflection and the respective end of the guide rail.
  • the solution according to the invention enables the use of a shorter guide rail than the known cable window lifters for a given window stroke. This enables a simpler assembly of the window lifter, in particular the cable deflections can be attached in an area of the door module in which they are easily accessible and therefore easy to assemble.
  • the shorter guide rail also saves material.
  • the cable window lifter according to the invention enables a larger pane stroke to be achieved with a predetermined length of the guide rail. This means that large window panes can be used even with an unfavorable ratio of window lift and door body.
  • the traction cable is suspended on the sliding part in such a way that the two cable sections of the traction cable are guided crosswise between the first cable deflection and the driver and between the second cable deflection and the driver on the sliding part.
  • the traction cable is guided from the first cable deflection to an area of the sliding part facing the second cable deflection, forming a first drainage point, from the first drainage point via an attachment point on the sliding part to an area of the sliding part facing away from the second cable deflection, and from the area second outlet point led to the second rope deflection or vice versa.
  • the areas on the sliding part from which the corresponding cable sections run to the cable deflections are defined as drain points.
  • the downward-pointing cable section is wrapped around the lower section of the sliding part and guided to the upper cable deflection, while the upward-pointing cable section is wrapped around the upper section of the sliding part and guided to the lower cable deflection.
  • the maximum disc stroke is increased by the distance between the drain points. If the driver is pulled by the traction cable into the lower end position on the guide rail, a movement of the sliding part only comes to an end when the upper drainage point facing the upper cable deflection is approximately at the same height as the lower cable deflection, since the traction cable then runs perpendicular to the direction of adjustment and no longer shows any force component in the direction of adjustment. The lower drain point has already been moved past the lower cable deflection. The same applies to the upper end position of the driver on the guide rail.
  • the maximum length of the sliding part is at a maximum displacement of the sliding part by half the distance of the drainage points from the lower cable deflection. If the upper and lower end positions are taken into account, there is an increase in stroke by the distance between the drain points.
  • Means are advantageously provided on the sliding part, which ensure that the rope sections of the traction rope which are guided and intersect on the sliding part are spaced apart from one another. This prevents the intersecting rope sections from interfering with each other.
  • the sliding part has a cable groove for guiding the traction cable, the cable groove regions of which are offset from one another in the region of the drainage points, so that the crossing cable sections of the traction cable are offset from one another in the region of the crossing and do not come into contact with one another.
  • the sliding part is preferably elongated and is rounded in particular in a circular manner in the region of its longitudinal ends. This enables the pull rope to be guided without kinks in the correspondingly provided rope grooves.
  • the traction rope is attached to the sliding part by means of a rope nipple.
  • the sliding part and the base part are preferably slidably connected to one another via a link guide. In this way, a safe and inexpensive longitudinal guidance is realized.
  • the sliding part and base part are connected to each other via a telescopic guide.
  • Figure 1 shows schematically the known structure of a cable window lifter.
  • An integral pull rope 1 or composed of several rope sections is wound around the rope drum 20 of a rope drive 2, which is driven by means of a hand crank (not shown) or by means of an electric motor.
  • the pull rope 1 is guided in a closed loop over a lower deflection roller 30 and an upper deflection roller 31. It can be provided that the traction cable is guided between the cable drive 2 and the upper or lower pulley 30, 31 in a Bowden tube.
  • a driver 5 is slidably fastened on a guide rail 4, to which a pane 7 to be adjusted by the cable window lifter is fastened via fastening means 9.
  • a pin of the driver 5 is guided through a disc hole, but any other fastening means 9 are also possible.
  • the driver 5 is connected to the traction cable 1 by means of a cable nipple 6, so that when the cable drive 2 is actuated, the driver 5 is displaced along the guide rail 4 between the deflection rollers 30, 31. There the driver 5 is connected to the window pane 7, the window pane 7 is raised or lowered in accordance with the actuation of the cable drive.
  • FIGS. 2 to 4 A driver according to the present invention is shown in FIGS. 2 to 4.
  • the driver 5 consists of a base part 51 which is slidably attached to a guide rail (cf. FIG. 1) via two lateral guide elements 51a and is displaceable along the guide rail between an upper and a lower end position.
  • the two guide elements 51a are spaced in the longitudinal direction, so that the base part 51 is reliably secured against tilting on the guide rail.
  • a sliding part 52 is slidably connected to the base part 51 and is slidable in the longitudinal direction of the driver 5 against the base part 51.
  • the sliding part 52 is elongated and has circularly rounded longitudinal ends 52a, 52b.
  • two stepped bolts 53 are provided, each of which are firmly connected to the slide part 52 and are guided with their lower, widened end regions 53a in an elongated link 51b of the base part 51.
  • the end regions 53a of the stepped bolts 53 are held in the link 51b by a projection 51c surrounding the link 51b.
  • the stepped bolts 53 can be moved longitudinally in the link 51b between an upper stop 501 and a lower stop 502.
  • the upper stop 501 cooperates with the upper step bolt 53
  • the lower stop 502 cooperates with the lower step bolt 53.
  • the maximum displacement of the sliding part 52 relative to the base part 51 or the achievable increase in stroke is equal to the length of the link 51b minus the distance between the stepped bolts 53.
  • the upper side of the sliding part 52 facing away from the base part 51 is closed off with a cover 54 for protection against dirt and moisture.
  • FIG. 3 the individual elements of the sliding part 52 covered with the cover 54 are shown in a view.
  • a pulling cable 1 is attached to the driver 5 by means of a cable nipple 6 of the pulling cable 1 anchored in the sliding part 52.
  • the cable nipple 6 is arranged in a cable nipple chamber 52c of the sliding part 52.
  • a circumferential cable groove 8 is provided, through which the pull cable 1 is guided crosswise on the sliding part 52.
  • Different rope groove areas are formed.
  • a first cable groove area 81 extends at one longitudinal end 52a of the sliding part 52
  • a second cable groove area 82 extends at the other longitudinal end 52b of the sliding part 52 (cf. FIG. 5).
  • the cable groove 8 has two cable groove areas separated by the cable nipple 6 on the long side of the sliding part 52 facing the guide elements 51a 83, 84 and on the longitudinal side of the sliding part 52 facing away from the guide elements 51a a cable groove section 85.
  • the cable groove regions 81, 82 and 84, 85 are offset from one another. Accordingly, the cable groove region 83 runs obliquely between the first cable groove region 81 and the cable nipple 6 according to FIG. 5. This configuration of the cable groove 8 ensures that the intersecting cable sections of the traction cable 1 are offset from one another and do not impede one another.
  • the course of the pull rope 1 is indicated in Fig. 3 by a center line.
  • the pull cable 1 is guided from a first deflecting roller 30 of the cable window lifter to a first drainage point A at one longitudinal end 52a of the sliding part 52.
  • the traction cable 1 is guided via the cable nipple 6 to a second outlet point B at the other longitudinal end 52a of the sliding part 52 and from the second outlet point B to the second deflection roller 31.
  • the drainage points A, B are arranged crosswise, ie the drainage point A is further away from the deflection pulley to which the corresponding rope section runs, when the driver 5 is between the deflection rollers 30, 31, than the drainage point B. The same applies to the Drain point B.
  • FIG. 6 shows a driver 5 according to the invention in the lower end position of the base part 51 on a guide rail 4.
  • the base part 51 is connected to the guide rail 4 via the guide elements 51a and between a lower stop 401 (FIG. 6) and an upper stop 402 (FIG 7) the guide rail 4 is displaceable.
  • the guide elements 51a encompass the leg 41 of the L-shaped guide rail 4.
  • the sliding part 52 is hatched in FIGS. 6 and 7 for better clarity and the base part 51 is shown in dotted lines.
  • the pulling rope 1 is guided in a first rope section la from the lower deflecting roller 30 to the upper outflow point A of the sliding part 52 facing the upper deflecting roller 31 (see FIG. 1). It runs from the upper drainage point A to the cable nipple 6, a tensile force being transmitted via the cable nipple 6 to the sliding part 52 and thus to the driver 5. From the rope nipple 6, the pull rope 1 runs to the lower guide point B facing away from the upper guide roller 31, from which it runs in a second cable section 1b to the upper guide roller 31.
  • the cable sections 1a, 1b cross at the side of the sliding part 52 in an area X.
  • the offset arrangement of the drain points A, B described with reference to FIGS. 3 and 5 ensures that the cable sections 1a, 1b do not touch.
  • the pull rope 1 is thus guided in a loop over the base part 52.
  • the crossed arrangement of the pull cable 1 on the driver 5 ensures that the stroke of the cable window lifter is increased by the distance between the drainage points A, B at a predetermined distance of the cable deflection rollers 30, 31. If the pull rope on the sliding part 52 were not crossed, a movement of the sliding part 52 in the direction of the deflection roller 30 would come to an end at the latest when the lower outlet point B was at the same height as the deflection roller 30.
  • a movement of the driver 5 basically only ends when the upper drainage point A of the driver 5 or the sliding part 52 is at the same height as the deflection roller 30.
  • a prerequisite for a maximum stroke gain is that a correspondingly large relative movement between base part 51 and sliding part 52 is also possible.
  • the sliding part 52 of the driver 5 on the base part 51 is initially in a non-displaced position, so that the upper edges of the sliding part 52 and the base part 51 terminate together. Arrived at the lower end stop 401 of the guide rail 4, the base part 51 of the driver 5 reaches its lower end position. After the base part 51 has reached its lower position on the guide rail, the sliding part 52 is further displaced with respect to the base part 51 by the cable force of the pull cable 1. The sliding part 52 is moved downward in relation to the base part 51.
  • the lower outlet point B of the sliding part 52 is moved beyond the lower cable deflection roller 30.
  • the window pane attached to the sliding part is thus moved to a point that lies beyond the deflection roller 30.
  • a displacement of the sliding part 52 only comes to an end when the drainage point A is at the same level as the deflection roller 30 or the sliding part 52 is displaced a maximum of the distance with respect to the base part 51.
  • the Relative movement between base part 51 and sliding part 52 is stopped by the stop of the lower bolt 53 on the lower stop 502 (cf. FIG. 4).
  • the sliding part 52 after reaching the upper end stop 402 is shifted in a corresponding manner relative to the base part 51 by the distance until the upper edges of the Complete the sliding part 52 and the base part 51 together again.
  • the sliding part 52 can also be displaced upwards relative to the base part 51 in the upper end position beyond the upper edge of the base part.
  • the cable guide of the pull cable 1 on the sliding part 52 takes place in FIG. 7 in accordance with the cable guide of FIG. 6, the cable section 1 a from the lower deflection roller 30 to the upper drainage point A now being of course significantly longer than that of the cable section 1b from the lower drainage point B runs to the upper pulley 31.
  • the crossing point of the rope sections 1a, 1b is again marked with X.
  • the embodiment of the invention is not limited to the exemplary embodiments specified above. Rather, a number of variants are conceivable which make use of the invention even in the case of fundamentally different types.
