Abstract
The invention concerns a cable-driven window lift for vehicles, in particular motor vehicles, and comprises a drive unit for the cable core (29) of the cable assembly (15), said cable core (29) being guided by deflecting means (16) over at least one substan-tially vertical path within which it is connected to an actuator (14) holding the window pane (9) preferably at its lower edge zone, the window pane (9) being guided by its side edges (10, 11) in guide rails (12, 13) resp. on the side of the vehicle and of the door. To achieve simple and accurate guidance of the pane at simplified design, the invention provides that the minimum of one actuator (14) shall move up-and-down with the cable core (29) in the absence of separate guides and that the deflection means (16) for the cable core (29) be mounted on the guide rails (12, 13) of the window pane (9).
Description
PCT/EP~tO21~1 1 CABLE-DRIVEN WINDOW LIFT
Description The invention concerns a window lift defined in the preamble of claim 1.-s A cable-driven window lift for motor vehicles is known from the German patent document 37 27 152 A1 which comprises a drive unit with two outputs for the cable which runs in endless manner as two mutually crossing loops. The cable is guided over four deflection rollers or rounded means mounted to the corner zones of twomutually-apart guide rails. Actuator plates for the window pane are guided in geometri-0 cally locking and sliding manner at the guide rails and are driven themselves by the cable system displacing the window pane. The pane itself is guided by its end edges in further guides present in the door, for instance in the manner disclosed in the German patent document 39 21289 C1. The known window lifts suffer from the drawbacks of complex design and foremost of excessively rigorous specifications for the pane guidance because ~s the guides for the window lift or for the ~ct~tors and the pane guides must be exactly matched to each other.
In the light of this state of the art, it is the object of the pleselll invention to so further develop the window lifts of the initially stated kind,that simple and accurate pane guidance at simplified design shall be achieved.
Essentially the invention solves this problem in that a ~ "~ of one actuator moves up-and-down together with the cable core and in that the cable deflecting means are mounted to the guide rails of the window pane. As a result the invention makes it possible to elimin~te the rails guiding the actuator(s) linked to the window pane~
- 216~473 -PCTIEP~4/02141 2 and as a result excessively rigorous specification for the guidance system no longer is required.
Consequently a more advantageous drive torque is also achieved. Another advantage is that the noise generated in the known window lifts with ~ctu~tor guide-rail s by the stick-and-slip behavior of said actu~tor at the guide rail -- which heretofore could be controlled only by complex and commensurately expensive rail coatings -- will hence-forth be elimin~ted. The elimination of the guide rails substantially decreases the hard-ware complexity of the-window lift, the deflecting parts in the form of deflection rollers or rounded parts being affixable to the very guides of the window pane. Accordingly the ,0 ~ llll of one ~ctll~tor will be guided by the pane guide also.
In a first and special embodiment of the invention, a minimllm of one actuator portion is guided in a closed loop and held by a clamp on the actuator. This feature allows easy adjustment between the window pane and the ~ctu~tQr to be affixed to the cable.
.s ~e invention achieves especially simple clamping in that the ."illi",.~ of one ~ctu~tor com~ises a preferably planar base element with a clearance to receive the cable-connecting clamp. As a result the actuator portion can be affixed to the cable core without need for a tool.
Very advantageously the clamp should comprise detent beaks glil,pillg from behind and in clamping manner the base element in the area of the clearance, as a result of which handling again is in~ploved.
In a further conception of the invention, the clamp comprises a chamber receiving a fastener rigidly attached to the cable and further it comprises cable passages at the chamber's end faces. The mutual ~tt~chment of cable and ~ctu~tor base element is carried out in that the cable by means of its retaining element, for instance in the form of a nipple, shall be guided like a loop through the clearance, whereupoll the relah~illg element shall be placed into the clamp's chamber and next the clamp shall be pressed onto the clearance of the base element. Thereby the cable core is rigidly joined to the ~ct~lator in rigid manner and the connection between the window pane and the drive will have been established.
To facilitate the assembly of the window lift, an adjustment system for the cable length of the cable system is provided and co-l-plises a spacer insertable at a separation site of the sheath of the cable system. As a result the cable may evince .0 initially some slack to allow passing it over the deflection means. The said slack is-elimin~ted following assembly by a spacer inserted into the separation site of the cable core.
Insofar the invention provides that the adjustment system colllplise a base body crossed by a borehole to pass the cable and an longitudinal slot to insert the spacer between the separation-site end faces of the cable assembly. Insertion of the spacer between the end faces of the cable assembly is much easier thereby.
Handling is further facilitated in that the base-body borehole co-llplise a stop for the cable sheath preferably in the vicinity of the longitudinal slot, so that this sheath can be more easily pulled out of said zone.
The spacer may be attached to the base body in especially simple manner in that it is kept clamped against the base body, for instance by detents and their mating means, as a result of which the spacer can be inserted without tools.
The invention moreover provides that the spacer shall peripherally grip the base body by means of arcuate wall extensions and that said spacer shall be secured . ., .~, . , 2165~73 PCT/EP~/021~1 4 - against axial shifting preferably between two rest shoulders formed in the base body. In any event such a design precludes undesired loosening of the spacer from the base body.
In a further concept of the invention, the spacer coln~ises a longitudinal-boss extension with a longitudinal channel to receive the cable core, the end faces of said extension rOlll hlg a stop for the ends of the cable sheath in the vicinity of the separation site. Thereby the adjustment system will be affixed in especially stable manner.Lastly the invention provides that the base body and/or the spacer of the adjustment system and/or the clamp be made of plastic.
Further objects, advantages, features and applications of the present .0 invention follow from the description below of an illustrative embodiment and in relation to the drawing. All described features and/or features shown in graphic form are objects of the present invention, whether considered individually or in arbitrary combinations, also regardless of being combined in the claims or how the claims relate to one another.~~
Fig. 1 is an elevation of the inside of a motor-vehicle door with a conceiv-able embodiment of a window lift of the invention, Fig. 2 is a perspective of a possible embodiment of the base element of the actu~tQr with clamp, Fig. 3 is the base element with clamp shown in Fig. 2 when in the assembly position, Fig. 4 is a perspective of a possible embodiment of an adjustment system of the invention to adjust the cable length, together with base body and spacer,-and Fig. S shows the base body and spacer of Fig. 4 but when in the assembly position immediately before the spacer will be inserted.
pcTlEn~/o214l 5 The vehicle door shown in Fig. 1 co~ ,-ises a lower door box 1 and an upper window frame 2. On its outside, the door box 1 is closed by an outer door skin 3 while as a rule being covered on the inside with door inside paneling. The door inside paneling was removed as shown in Fig. 1, whereby the window lift mounted in the door box can be seen. The window frame 2 COIllpl ises an upper frame portion 4, a rear frame portion 5 and a front frame portion 6. The shown door is typically affixed by its front side 7 by means of an omitted hinge to a retaining post of the vehicle, whereas the rear side 8 co~"p-ises an omitted door-lock component.
The window frame 2 receives a window pane 9 m~tchine its peripheral contour and which, in Fig. 1, is shown half open. The window pane 9 is guided at its front edge 10 and at its rear edge 11 resp. in a front and rear guide rail 12 and 13. In the selected embodiment, an ~ctu~tor 14 is clamped to the lower end zone of each corner and the cable-core 29 of a cable assembly 15 is attached to said actuator. The cable assembly 15 is guided over four deflection means in the form of deflection rollers 16 affixed inside the door box 1 to the upper and lower ends of the two guide rails 12 and 13. The cable assembly 15 is guided in crossing manner over the deflection rollers 16 and~
runs toward an omitted shaft 17 of an omitted window crank or an electric drive. De-pending on the direction of rotation of the shaft 17, the cable core 29 will be pulled in one direction or the other, whereby the ~ctu~tors 14 displace the window pane 9 up or down.
As shown by Fig. 1, the actuators 14 can be moved up and down by the cable core 29 without separate guides. The ~ctu~tQrs 14 are guided solely by means of the window pane 9, that is by this pane's guide rails 12 and 13. As a result excessive specifications regarding pane guidance are avoided.
216~473 Figs. 2 and 3 show how to affix such an actuator 14 to the cable assembly 29. The ~ct~l~tor 14 is fitted with a planar base element 19 con~ ising an omitted seat for the window pane 9. The planar base element 19 col~)lises a clearance 21 wherein a clamp 20 in the form of a clip may be fastened. Illustratively such fastening is imple-mented by detent beaks 27 at the clamp 20.
The clamp 20 co,np,ises a chamber 24 receivhlg a retaining element 30 rigidly joined to the cable core 29. This retaining element 30 assumes the form of a nipple and preferably is made of metal and it is crimped in immovable manner onto the cable core 29. The connection between the cable core 29 and the window pane 9 is.0 implemented in that the cable core 29 together with the nipple 30 as shown for the planar base element 19 of Figs. 2 and 3 is made to pass from below in the manner of a loop through the clearance 21 of the base element 19. Next the nipple 30 is placed in the chamber 24 of the clamp 20, the cable segments running each side of the nipple 30 being thereby located in the passages 25 of the end faces of the clamp 20. Then the clamp 20 s is pressed into the clearance 21 of the base element 19, the said cable portions on each side of the nipple 30 being made to pass through the slots 22 present in the base element 19, without thereby l~m~ging the cable core 29. As a result the cable core 29 is linked to the ~ctu~tor so it cannot move relative to it and thereby also the window pane 9 is fixed relative to the drive of the window lift. ~~
To facilitate window-lift assembly, the cable core 29 initially will offer some slack so that it may be easily looped around the deflection rollers 16. However after the cable core 29 has been mounted, the slack must be removed to assure proper operation.
To make possible such additional adjustment regarding the length of the cable assembly 15 or of the cable core 29, a cable-length adjustment system is inserted into the cable 2165~73 assembly 15 as shown by Figs.4 and 5. For that purpose the sheath of the cable assembly 15 is interrupted and a base body 33 is inserted between the two ends of the sheath 32.
The base body 33 comprises a borehole 35 for the cable assembly 15 with a longitudinal`
slot 38 to insert a spacer 39 between the end faces of the sheath 32 that are formed by s the separation of said sheath.
In the state shown in Fig. 4, the cable core 29 is of such length that it can easily be placed over the deflection rollers 16. In that state of assembly, the sheath 32 of the cable assembly 15 is inserted in the longitudinal slot 38 of the base body 33 and rests against the stop 37 of the borehole 35. In order to tension the cable core 29 when .0 in this position, the portion of the sheath 32 resting in the longitudinal slot 38 is pulled out and only the cable core 29 shall remain in the manner schematically indicated in Fig.
5. Next the spacer 39 is inserted in such manner between the two rest shoulders 36 and onto the base body 39 that the cable core 29 will rest in the longitudinal channel 42 formed in a longitudinal boss 41 of the spacer 39. The wall projections 40 of the plastic spacer 39 resiliently give way during insertion and ultimately will peripherally enclose the retraction formed by the rest shoulders 36 at the base body 33, essentially being flush with the rest shoulders 36. Thereby the spacer 39 is prevellled from accidentally detaching from the base body 33.
To implement length adjustment, it is also possible to use spacers 39 of different lengths L to compensate for additional tolerances. In this procedure the spacer 39 is kept by the cable tension, and by the entailed conll~lession against its end face, in an axial rest position against the rest 36 of the base body 37.

On its outside, the door box 1 is closed by an outer door skin 3 while as a rule being covered on the inside with door inside paneling. The door inside paneling was removed as shown in Fig. 1, whereby the window lift mounted in the door box can be seen. The window frame 2 COIllpl ises an upper frame portion 4, a rear frame portion 5 and a front frame portion 6. The shown door is typically affixed by its front side 7 by means of an omitted hinge to a retaining post of the vehicle, whereas the rear side 8 co~"p-ises an omitted door-lock component.
The window frame 2 receives a window pane 9 m~tchine its peripheral contour and which, in Fig. 1, is shown half open. The window pane 9 is guided at its front edge 10 and at its rear edge 11 resp. in a front and rear guide rail 12 and 13. In the selected embodiment, an ~ctu~tor 14 is clamped to the lower end zone of each corner and the cable-core 29 of a cable assembly 15 is attached to said actuator. The cable assembly 15 is guided over four deflection means in the form of deflection rollers 16 affixed inside the door box 1 to the upper and lower ends of the two guide rails 12 and 13.

As shown by Fig. 1, the actuators 14 can be moved up and down by the cable core 29 without separate guides. The ~ctu~tQrs 14 are guided solely by means of the window pane 9, that is by this pane's guide rails 12 and 13. As a result excessive specifications regarding pane guidance are avoided.
216~473 Figs. 2 and 3 show how to affix such an actuator 14 to the cable assembly 29. The ~ct~l~tor 14 is fitted with a planar base element 19 con~ ising an omitted seat for the window pane 9. The planar base element 19 col~)lises a clearance 21 wherein a clamp 20 in the form of a clip may be fastened. Illustratively such fastening is imple-mented by detent beaks 27 at the clamp 20.
The clamp 20 co,np,ises a chamber 24 receivhlg a retaining element 30 rigidly joined to the cable core 29. This retaining element 30 assumes the form of a nipple and preferably is made of metal and it is crimped in immovable manner onto the cable core 29.

To make possible such additional adjustment regarding the length of the cable assembly 15 or of the cable core 29, a cable-length adjustment system is inserted into the cable 2165~73 assembly 15 as shown by Figs.4 and 5. For that purpose the sheath of the cable assembly 15 is interrupted and a base body 33 is inserted between the two ends of the sheath 32.
The base body 33 comprises a borehole 35 for the cable assembly 15 with a longitudinal`
slot 38 to insert a spacer 39 between the end faces of the sheath 32 that are formed by s the separation of said sheath.
In the state shown in Fig. 4, the cable core 29 is of such length that it can easily be placed over the deflection rollers 16. In that state of assembly, the sheath 32 of the cable assembly 15 is inserted in the longitudinal slot 38 of the base body 33 and rests against the stop 37 of the borehole 35. In order to tension the cable core 29 when .0 in this position, the portion of the sheath 32 resting in the longitudinal slot 38 is pulled out and only the cable core 29 shall remain in the manner schematically indicated in Fig.
5. Next the spacer 39 is inserted in such manner between the two rest shoulders 36 and onto the base body 39 that the cable core 29 will rest in the longitudinal channel 42 formed in a longitudinal boss 41 of the spacer 39. The wall projections 40 of the plastic spacer 39 resiliently give way during insertion and ultimately will peripherally enclose the retraction formed by the rest shoulders 36 at the base body 33, essentially being flush with the rest shoulders 36. Thereby the spacer 39 is prevellled from accidentally detaching from the base body 33.
To implement length adjustment, it is also possible to use spacers 39 of different lengths L to compensate for additional tolerances. In this procedure the spacer 39 is kept by the cable tension, and by the entailed conll~lession against its end face, in an axial rest position against the rest 36 of the base body 37.
