Description

The invention relates to a device for connecting a window pane with a motor vehicle window regulator according to the preamble of claim 1.

From the JP-6-135228 a device for connecting a motor vehicle window glass with a window lift is known, wherein the lower edge of the window pane is connected to two disc holders, each having two spaced-apart webs with a wedge-shaped tip. Two staple-shaped drivers connected to a power window device have a bevelled lead-in area and an undercut cavity for positive reception of the wedge-shaped tips of the disc receivers connected to the window pane. To secure the connection of disc holder and driver is due to the only slight positive connection between the wedge-shaped tips and the undercut cavity each provided a leg of the driver piercing bore for receiving a screw, with which the legs of the driver are clamped and thereby the position of the wedge-shaped Tips of the disc mounts is secured in the drivers.

In this known device for connecting a motor vehicle window glass with the drivers of a window is an exact alignment of the form-locking elements of the disc holder and the driver to each other and an additional non-positive tension of the driver to secure the connection of disc holders and drivers required, for which during the assembly a visual contact to the lanyards and the accessibility to the carriers is required. To connect the window pane with the window lifter therefore an open door slot and a longer installation time is necessary, which leads to considerable costs during installation.

Another problem with the known device for connecting a motor vehicle window with a window is that for the preparation of the screw for clamping the Mitnehmerschenkel a screw through an opening of the door shaft must be used so that there is a risk that the mounting screw in the Door shaft falls or insufficient screw is made, which leads to operating noise during operation of the window and thus to the dissatisfaction of the motor vehicle occupant.

The object of the present invention is to provide a device for connecting a window pane connected to a window mount with a driver of a window lifter of the type mentioned above, which allows blind mounting, a secure connection between the window pane and the window lifter and easy installation without risk of Loss of a fastener guaranteed.

This object is achieved with the features of claim 1.

The solution according to the invention allows a blind assembly in the connection of a window pane with a motor vehicle window, ie a mounting even in the absence of visual contact with the connecting means in the door shaft of a motor vehicle door. It ensures a secure connection between the window and the window and a simple and safe installation, in which the fitter can control the individual assembly steps and thus the completion of the connection without visual contact without the risk of loss of a fastener.

The inventive solution is based on a pre-installation of the fastening device on a coupling body of the driver, which is connected to the base body of the driver or formed thereon. By attaching a formed on the disc receiving coupling portion on the fastening device in a mounting direction for connecting the disc holder with the driver initially a loose, positive connection between the disc holder and the driver is made and then by pressing the attachment means of the coupling portion of the disc holder with the coupling body of the driver clamped non-positively.

Due to the positive connection between the disc holder and the driver in a first assembly step, a blind assembly without direct visual contact with the fastening device and the coupling portion of the disc holder is made possible and by pressing the fastening device in a second assembly step, a frictional connection between the coupling portion of the disc holder and the coupling body of Driver ensured by clamping the coupling portion between the coupling body and the fastening device.

Preferably, the fastening device is perpendicular to the mounting direction for connecting the disc holder with the driver adjustable and has a perpendicular projecting from the coupling body of the driver threaded bolt with a bolt shank and a bolt head, while the coupling portion of the disc holder aligned with the mounting direction for connecting the disc holder with the driver Longitudinal slot, which is attachable to the bolt shank of the threaded bolt, wherein the coupling portion of the disc holder between the coupling body and the bolt head of the threaded bolt by adjusting the threaded bolt is frictionally clamped.

The design of the fastening device than perpendicular projecting from the coupling body of the driver threaded bolt, the bolt shaft is already connected before installation of the disc holder with the coupling body and in particular screwed avoids a separate installation of the fastening device for connecting the disc holder with the driver during the assembly process, while with the mounting direction for connecting the disc holder with the driver aligned longitudinal slot in the coupling portion of the disc holder allows easy alignment and positive connection of the disc holder with the driver, so that subsequently the coupling portion of the disc holder between the coupling body and the bolt head of the threaded bolt is frictionally clamped.

For this purpose, the fastening device comprises an internal thread arranged in the coupling body, which engages with an external thread of the bolt shank, wherein the internal thread is preferably arranged in a fastening insert inserted into the coupling body of the driver.

The interaction of an arranged in the coupling body internal thread with the external thread of the bolt shank allows a screw for clamping the coupling portion of the disc holder with the coupling body of the driver and thus a defined determination of the clamping force for permanent, non-positive connection between the disc holder and the driver.

The arrangement of the internal thread in an insert, which is preferably formed in the coupling body of the driver or inserted by compression molding, prevents a reduction of the clamping force due to thermal expansion, so that a firm, rattle-free connection between the disc holder and the driver is ensured.

As an alternative to a screw connection, it is also possible to provide a different type of clamping connection, which is designed, for example, in the manner of a turnbuckle, a latching device or the like.

To produce the frictional connection between the disc holder and the driver, the bolt head is preferably designed such that the threaded bolt can be screwed in and out with a tool into the internal thread of the coupling body, wherein a washer can be arranged between the bolt head and the coupling portion of the disk holder.

By a positive connection of the example formed as a hexagon bolt head with a trained example as Allen key with a hexagon tool, the required tension between the disc holder and the driver can be made through an opening in the door shaft. Alternatively, the use of a connected to the bolt head deflection mechanism is possible, so that the operation of the threaded bolt can be done from the parapet slot or the shaft bottom of a door shaft.

Preferably, the coupling body of the driver is formed as laterally protruding from the base body of the driver arm, while the base body of the driver has an isolation buffer on which the window rests when the disc holder is connected to the driver.

By this association between the coupling body of the driver and the disk shaft of the disk holder a safe, tilt-free arrangement of the window is ensured, the isolation buffer serves to prevent tension and rattling noise between the window and the driver.

For ease of manufacture and securing the position and orientation of the disc holder of the coupling portion of the disc holder is formed as an extension of a first side wall of the disc holder, which forms a disc slot for receiving the window pane spaced from a second side wall, wherein the bottom of the disc slot on an upper edge of the coupling body of Driver rests when the disc holder is connected to the driver.

In a further embodiment of the solution according to the invention, the lower edge of the coupling portion of the disc receiving an insertion bevel, which is arranged in an arrangement of a longitudinal slot in the coupling portion of the disc holder on both sides of the aligned perpendicular to the lower edge of the coupling portion longitudinal slot.

The insertion bevel facilitates the connection of the disc holder with the driver and allows a blind assembly by the insertion beforehand guides the longitudinal slot of the disc holder on the projecting from the coupling body of the driver bolt shank of the threaded bolt.

Furthermore, by forming a shoulder between the lower edge of the coupling portion of the disc holder and the insertion, which faces a lower edge of the coupling body of the driver or rests against this, when the disc holder is connected to the driver, the connection between the disc holder and the driver also then secured if the threaded bolt is insufficient Clamping force between the coupling portion of the disc holder and the coupling body of the driver produces.

The disc holder may optionally consist of a punched-bent part or a plastic injection molded part, wherein in the formation of the disc holder as a plastic injection molded part at least in a part of the slot of the connecting portion of the disc receiving a metal insert for receiving the threaded bolt is arranged to produce a torque drop to prevent the clamping force between the coupling portion of the disc holder and the coupling body of the driver.

In the Fig. 1 and 2 are in different perspective views of a driver 1 and formed as a punched-bent part disc holder 5 for connecting a window glass 10 with a cable window lifter, of which an upper guide roller 11 can be seen in the assembled state and in the FIGS. 7 and 8 shown separated from each other. The window pane 10 is inserted into a disk shaft 6 of the disk receptacle 5 formed by two spaced-apart side walls 61, 62 and a bottom 63 and optionally connected to the disk receptacle 5 with additional fastening means, for example by gluing or by further positive connection measures.

The driver 1 consists of a base body 2 and a coupling body 3, which is formed as laterally projecting from the base body 2 arm with an upper edge 31 and a lower edge 32. The base body 2 is connected via a guide slot 20 with an in Fig. 9 shown guide rail 12 of the motor vehicle window and connected has one of Fig. 7 to be removed Seileinhängung 13, in which a window lifter rope for raising and lowering of the driver 1 and thus the window pane 10 is mounted.

The coupling body 3 of the driver 1 to be connected to the disk holder 5 has one of the Fig. 3 to be removed contact surface 30 and a bore or recess 33, in accordance with Fig. 4 an insert 4 with an internal thread 40 is inserted or molded. In the internal thread 40 of the insert 4 in the coupling body 3 of the driver 2, the external thread is screwed to a bolt shank 82 of a threaded bolt 8, which has a hexagonal bolt head 81.

The disc holder 5 further has a coupling portion 7 which is formed as an extension of a side wall 61 of the disc shaft 6 and includes a longitudinal slot 70 which is slightly wider than the pin shaft 82 of the threaded bolt 8. At the opposite end of the disc shaft 6, the coupling portion 7 of the disc holder 5 has two laterally of the longitudinal slot 70 formed Einführungsschrägen 71, 72 which are formed on substantially projecting from the coupling portion 7 paragraphs 75, 76 and at an oblique angle to the coupling portion. 7 run. The laterally adjacent to the longitudinal slot 70 edges 73, 74 of the insertion bevels 71, 72 are also chamfered so that they at the ends of the insertion bevels 71, 72 have a greater distance from one another than the side edges of the longitudinal slot 70th

At the driver base body 2, an insulating buffer 9 is formed, which is formed substantially rectangular in shape and contains a damping layer 90 in the form of an elastic plastic or rubber as the outer surface. The inserted into the disk shaft 6 window 10 is in the mounted state on the damping layer 90 of the insulating buffer 9, thereby preventing the window 10, the driver 1 contacted directly.

The Fig. 1 and 2 show the driver 1 and the disc holder 5 in an intermediate position of the assembly in which the longitudinal slot 70 of the coupling portion 7 of the disc holder 5 on the bolt shaft 82 of the previously with the coupling body 3 of the driver 1 by screwing the bolt shaft 82 into the insert 4 in the coupling body 3 connected threaded bolt 8 is attached.

The 3 and 4 show from a different perspective view of the coupling body 3 of the driver 1 by screwing the external thread of the bolt shaft 82 into the internal thread 40 of the insert 4 in the coupling body 3 connected threaded bolt 8 and introduced, for example, through the slot of a door railing in a door slot disc holder 5 with the in The threaded shaft 82 of the threaded bolt 8 is screwed into the insert 4 so far that a secure connection between the coupling body 3 and the threaded bolt 8 is ensured, but a sufficient distance between the bolt head 81 and a at the bolt head 81 adjacent or trained washer 80 and the contact surface 30 of the coupling body 3 is adhered to the insertion of the coupling portion 7 of the disc holder 5.

The disc holder 5 is moved with the coupling portion 7 in the direction of the threaded bolt 8, wherein the insertion bevels 71, 72 and the oblique edges 73, 74 in accordance with Fig. 2 facilitate the threading of the longitudinal slot 70 on the bolt shaft 82 and thereby bring the coupling portion 7 in the corresponding position for connection to the coupling body 3 of the driver 1.
