Description

DEVICE FOR FIXING AN ADJUSTABLE WINDOW OF A VEHICLE OF MOTOR TO THE GUIDE MECHANISM OF A WINDOW ELEVATOR DESCRIPTION The invention relates to a device for fixing an adjustable window of a motor vehicle to a guide mechanism of a window lifter, according to the introductory clause of claim 1, wherein the installation and adjustment of the window are simple and safe, and the operational reliability of the window increases at the same time. DE 43 16 651 A1 discloses a fastening device for connecting a fastener of a window lifter to a window, wherein a fastener component of the fastener in the form of a bolt engages an opening within the window. The diameter of the bolt head is enlarged in relation to the cavity. The bolt is inserted perpendicularly to the surface of the window, within the opening of the window with a corresponding diameter, and subsequently moves to a guide area. The dimensions of the guide area in this way correspond to the diameter of the body or tree. DE 31 08 244 A1 discloses a coupling device between a window lift and a window of a motor vehicle, which basically consists of a locking device fixed to the lower edge of the window and at least one coupling clamp which is equipped with an immobilization means and projecting towards a coupling component which is equipped with adaptable locking components and connected to the window lifter mechanism. When the connecting components are joined, this results in an elastic deformation of at least one of the coupling components until the connection is carried out by the interengagement of the components. However, a disadvantage is that in order to carry out the connection between the window and the window lifter, the expansion area must have a minimum resilience, so that the immobilization components can be interconnected. However, this resilience also presents the risk that, in the case of heavy loads such as those that may arise when the window freezes and joins the frame, the immobilization components are released again. This would mean that the window lifter mechanism can no longer perform its function. In addition to this, it is difficult to place the immobilization components precisely in relation to one another so as to be able to inter-link. Therefore, it is often necessary to move the window back and forth in the X direction in order to carry out a positive immobilization. JP 6-135228 A describes a device for connecting a window to a window lifter. On the window lifter there are U-shaped profile components running parallel to the lower edge of the window, whereby the free sides of the U-shaped profile have extensions similar to hooks pointing inwards. Corresponding to these profile components are the adaptable coupling components which can be immobilized within the U-shaped cavity. These coupling components are fixed to the lower edge of the window. In order to facilitate connection, the free ends of the coupling components are wedge-shaped and their extensions with tabs can be attached to the U-shaped profile extensions. However, it is generally necessary for the worker to apply pressure on the window in the mounting direction, in order to carry out the required positive locking. Screws are used to fix the area between the window lift and the window in line with the cavities and grooves. There is a small possibility of adjusting the window in the X direction (longitudinal axis of the vehicle) in order to reach an ideal position as it meets the design that was initially described. DE 44 23 440 A1 describes an additional window connection using regions that are elastically deformed and therefore pivotable. The pivotable regions form the upper edge of the recess of two parallel lateral sides, in which a connection component of the window can be immobilized. Suitable connecting components are supposed to be a bolt placed in a window cavity, a component adhered to the window or a component formed with the window itself. Even this fixing device has the disadvantage that the elastic fields of the lateral sides have a reduced load bearing capacity. Therefore, there is a risk that a connection will detach in the event that strong forces appear on the window. An object of the invention is to create a device that immobilizes itself during the window assembly on the window lifter in such a way that the weight of the window is sufficient for the interengagement of the components and also to ensure that the window can be Adjust in the X direction. In addition to this, in comparison with other devices previously, the fixing device according to the invention must significantly increase the load-bearing capacity in relation to the window. The object of the invention is carried out through the features of claim 1. The subclaims describe different embodiments of the invention. According to the invention, there is an inlet conduit for insertion of the retainer into an elongated recess extending in the X direction so that there is no need for elastic / expansion fields of the fixing device. This is facilitated by a functional division of the fixation device in two areas: specifically within an area exclusively for insertion of the retainer into the positive locking area of the associated component of the fixation device.; and in another area exclusively to transfer the displacement forces of the window lifter. The transfer of the retainer from the entrance area to the interior of the joint area formed by the elongated recess takes place by means of displacement in the X direction. This displacement can be initiated either by the worker or automatically by aligning the window in the frame of the motor vehicle door during the first closing operation of the window lift. In order to ensure reliable operation of the fastening device according to the invention, it is important that after the window assembly, the vertical shafts of the entrance area (the inlet duct) and the retainer are positioned at least as as far as possible from each other to ensure a sufently large overlap between the retainer and the elongated recesses and therefore a sufent load-bearing capacity of the fixing device. In addition to this, there must be a means to prevent any unwanted slippage of the seal out of the elongated recess into the interior of the inlet duct. The fixation device will not work if this happens. On the other hand, it is necessary not to impede the assembly movement and, on the other hand, it is necessary to avoid the backward movement of the retainer. A simple and appropriate solution is the use of toothed locking components placed on the one hand towards the component supporting the retainer, and on the other hand on the component supporting the extended recess, whereby these immobilization components are interconnected by means of a spring. The vertical side of the serrated profile in this way points contrary to the direction of mounting the retainer. The elasticity of the spring of the connection of the locking components allows a problem-free assembly of the fixing device, since the locking components simply slide on one another in the mounting direction. It is useful if the width of the inlet duct and the space of the retainer correspond as closely as possible. In order to facilitate the entrance of the retainer, the retainer has a rounded -possibly circular- contour in its lower area, at least. In addition, at the front of the inlet duct, there are conical guide surfaces that open in the direction of the detent. The two components of the fastening device according to the invention can be connected to the window or to the window guide mechanism, as chosen. This means that any catch is fixed to the window and the corresponding elongated recess is fixed to the window lift guide mechanism or the other rounded track. Ideally, the component connected to the guide component will form a single homogeneous component, with the fastener of a window lifter cable. The component to be connected to the window also forms a single component and for example adheres to the lower edge of the window or is positively immobilized in a window cavity in the region of the lower edge of the window. If synthetic windows are used, it is also possible that the corresponding component is molded in the material of the window. The forces exerted on the windows can differ signintly from one vehicle to another. Consequently, therefore, the stability requirements of the force transfer components also vary greatly. For example, it may be sufent in many cases for the components of the fixation device according to the invention to be made of synthetic material. In other cases, it is necessary to use light die-cast metal to produce components that are capable of supporting a load. For design reasons, when such metal components are used, it may not be possible to incorporate a spring area which allows sufent exclusion of the spring for the locking components. In this case, a separate spring component must be used, which allows the locking components to slide over one another during the assembly of the window. In addition to this, however, other kinds of safety mechanisms can also be used to prevent backward movement, for example screws, adherents, etc. The invention will now be explained in more detail with reference to the embodiments of the invention as illustrated. The drawings show: Figure a schematic diagram of the invention before the window assembly.

The schematic diagrams a clearly and simply illustrate the principle of the present invention. According to the invention, the fixing device consists of a first component with a retainer 2 and a second component 1 with a horizontal elongate recess 12, which acts as a guide conduit and a joint area for the retainer 2 once that the latter has been inserted into the side entry conduit 10, which is oriented towards the retainer. The invention can be used anywhere where the window has a lateral displacement which is sufficient to allow the retainer 2 to be positioned through the inlet conduit 10. The conical guide surfaces 11 placed before the inlet conduit 10 facilitate what is called "blind assembly", whereby the connection takes place without visual supervision. A further advantage relates to the free assembly of tools through the invention particularly suitable for use on so-called modular supports which form a moisture-proof division between an external wet area and an internal dry area of the vehicle door. Since no tools are required to connect the window to the window lifter, it is also possible to supply mounting slots in the partition and the subsequent sealing thereof. The figure shows the beginning of the window assembly process, using a vehicle door with a double pull cable window elevator which is not illustrated, so that component 1 is supposed to represent the area of the fastener, the which connects positively with the wire loop of the window lift. First, the window 3 is inserted through the door shaft into the inner door work body 4 (mounting direction 30) and is made to defend until the bolt-shaped retainer 2, which is placed in a The window cavity has penetrated into the inlet duct 10 and is located on the base of the elongated recess 12. In a second assembly step, the window 3 moves horizontally in the mounting direction 31 until it has reached its correct position. This is associated with the displacement of the retainer 2 into the joint area (recess 12) of the component 1. Accordingly, there is a gap between the vertical center axes 100, 200 of the inlet conduit 10 / retainer 2, respectively. In order to prevent backward movement of the retainer 2 contrary to the mounting direction 31, and the associated risk of window release, unilateral locking components are provided, which are explained in more detail in the following embodiments of the invention. invention.

However, at this stage, it should be noted that in the case of the double-wire cable window lifts, the immobilization components are only necessary on the fixing device of one of the guides. The retainer of the other fixing device is supposed to move "freely" in the elongated recess 12 and therefore balances the parallelism tolerances of the two guides. The design of the fixing device according to figures 2a to 3b is such that its components 1, 2 can be conveniently manufactured by injection of synthetic material. The high degree of integration means that the fastening device including the fastener with the nipple chamber 19 and hooks 18, consists of only two components 1, 2. The component 2 comprises a bolt-like retainer 20a, which is placed asymmetrically on a component 21a with a reinforcement 22a. Corresponding to the reinforcement 22a is the lower edge of the window 3 which can support itself on the raised supporting surfaces 24a, 25a. At the lower edge of the reinforcement 22a, are the immobilization components 23a, and after the window assembly, they are interconnected with the opposite immobilization components 17 of the component la. The immobilization component 20 is higher on the side of the connection component 21a which is on the window surface 3 on the other side (which is not visible). The difference corresponds approximately to the thickness of the window. It is advantageous that the component 2a is equipped with a mechanism against losses, so that it can not fall out after it has been cut out in the window cavity. The component on the guide side is shown from two angles in Figures 2a and 2b. It consists of parallel lateral sides 14, 15 which are connected to each other by means of the base 13. The lateral side 14, which only supports the recess 12aa on its inner side, must be shortened in order to ensure a deformation of the injection tool within the scope of the desired high degree of integration. Constructed inside the inner side of the other lateral side 15 is the recess 12a as well as the lua conduit. I ivid-i with lu-j conical guide surfaces lia which are placed in the front of it. The outer side of the side side 15 rests on the hooks 18 which are positively immobilized with the guide, and also support the nipple chamber 18 by means of which a positive locking is ensured with the wire loop that transfers force from the elevator of window. During the window assembly, the component 2a, which is fixed around the lower edge of the window, advances into the interior space of the component la. In this way the retainer 20a first comes into contact with a tapered guide surface Ia before it travels through the inlet conduit 10a. When the lowest position is reached, the toothed locking components 17, 23a are also connected to each other. When the retainer 20a is displaced within the recess 12a, 12aa (in the mounting direction 31), the locking components 17, 23a slide over one another, whereby the reinforcement 22a is bent upwards towards the lower edge of the recess 20a. the window 300. Backward movement by the serrated contour of the immobilization components 17, 23a is prevented. The cross sections of Figures 3a and 3b show the position of the retainer 20a in the recess aa after the complete assembly of the window. The fixing device according to figures 4a and 4b shows different angles after the complete assembly of the window and the component is used as the component on the guide side which is identical to the component la in figure 2b and in the Figure 2c, respectively. The other component 2b has a support panel 28 with a retainer 20b, and on the upper end of the support panel there are two essentially parallel lateral sides 27 which accommodate the window 3. Regarding the fixation of the component 2b, it generally adheres to the bottom edge of the window 3. From the cross sections of the figures 5a and 5b, the position of the retainer 20b within the elongated recess 12a is clearly visible. Even the shape of the immobilization components 17, 23b clearly shows that during the assembly movement of the component 21:, of the inlet conduit 10b within the recess 12a, the locking components can be slid on one another. The immobilization units 23b which are placed on the reinforcement 22b in this way are pushed up towards the opening 2ßb. A backward movement towards the inlet duct 10b is prevented by the corresponding toothed part of the locking components 17, 23b. In contrast to the embodiments of the invention mentioned above, the embodiment of the invention shown in FIGS. 6a to 9e has the elongated recess 12c on the component le, which is to be securely attached to the window 3, while the component 2c on the guide side supports the retainer 20c. In addition, the immobilization components 17c, 23c have been moved to the lateral surfaces of the components le, 2c. This embodiment of the invention is also suitable for use as a die-cast component of light metal. Due to the shortened lateral side 14c of the component 2c, during the window assembly there may be sufficient tilting movements between the components le and 2c to allow their immobilization movements 17c, 23c to slide on one another as necessary. However, in all other aspects, assembly takes place using the basic procedure already described. Therefore, the component which is fixed to the window 3 is directed towards the component 2c on the side of the window lifter until it positively immobilizes the retainer 20c of the component 2c by means of its conical guide surfaces 11c, the conduit Entrance 10c and recess 12c. In this step, it should be noted that the retainer 20c does not necessarily have a bolt-like contour. Elliptical or angular contours, or combinations thereof, may also be used. However, it seems advantageous if rounded contours are used at least on the side of the retainer 20c which is oriented towards the inlet duct. With respect to the outer side of the lateral side 15c, it supports a holding area 190 with the nipple chamber 19 as well as hooks 18 for adjustable connection of the component 2c to the guide of a cable window lifter.
