EP0694669B1 - Device for connecting a window glass with a window regulator - Google Patents

Description

The invention relates to two devices for connecting a motor vehicle window with a window regulator according to the preamble of claims 1 and 11 and is characterized by a simple structure when used only a few individual parts. In addition, the Invention a simple assembly process.

There are different types of connection devices a window with a window known. Man distinguishes fundamentally positive, z. B. snap Connections, non-positive clamp connections and Adhesive connections.

A generic device for connecting a motor vehicle window with a window regulator, the one provides non-positive clamping connection describes DE 42 18 425 A1. After that, the window pane between clamped two rubber-coated jaws, the Clamping force from a screw connection above one Support between the two jaws is generated.

This connection variant has the advantage that the The pane can be easily inserted into the door shaft can, even if the washer seals are already installed in the door shaft. However, it is disadvantageous the variety of parts that make up the device.

From EP 0 208 237 B1 is a support element for connecting the Window pane with a corresponding guide device known, the several, on both sides of the lower edge of the window pane arranged support wings. One of Support wing carries a pin that has a hole in the window pane assigned. When inserting the window pane these bend between the elastic support wings outside until the pin clicks into the disc hole.

However, the disadvantage in the assembly process is difficult achieving correspondence between the disc hole and the pin to be snapped into it. For a secure snap to ensure must because of inevitably occurring Manufacturing tolerances a certain excess of the distance of the Pen from the base surface on which the lower edge of the pane strikes, be provided. This makes it a game created that especially when reversing the direction of movement the window pane can cause noise. About that also requires the preparation of the carrier described because of its complex structure a relatively complex one Tool.

Another snap-on coupling device between Window and window lifter are shown in DE 31 08 244 A1. she consists of two interconnected channel-like Profiles, one of which is an area of the lower edge of the pane encloses and is attached there. The other after bottom open profile carries inward ends at its ends Hooks with protrusions of angular elements of the Lifting device can engage, creating a positive connection can be reached. According to the proposal should snap through the fasteners the movement of the window pane against the upper stop position be enforced, thereby creating an automatic Align the pane in the frame construction takes place and additional handles during assembly are not necessary.

However, since the profile-like coupling element on the lower edge of the disc must be preassembled, so it leads associated thickness buildup regularly to a difficult Introduction of the window pane into the door shaft. Because of the necessarily missing seals in this area Therefore, there is always damage during assembly of the paint. Another problem can arise in the Minimum snap area of the coupling elements required Represent tolerances to switch noise when Prevent operation of the window regulator.

From DE 38 17 260 C2 one in the area of the lower edge of the Window pane known from glued lifting rail. They are also to be installed outside the door.

CH-A-473 987 discloses a holding clip for holding a skylight dome on its skylight base. The bracket consists of an upper clamp and a lower clamps, which are provided with clamping pieces. A spring force is applied to the dome shell exercised.

The holding clip known from CH-A-473 987 serves to compensate for different manufacturing tolerances and different types of skylights with one and the same To be able to hold the retaining clip on the curb. she is for connecting a motor vehicle window to a Window lifters not suitable.

The invention has for its object a device for connecting a motor vehicle window pane to a To develop window regulators that are characterized by a constructive simple construction and easy to manufacture as well as ease of installation distinguished. The window pane should before they were introduced into the door shaft, no additional parts carry. If necessary, the device should be simpler Can also be combined with other connection technologies to be able to increase security in manufacturing to achieve the connection. At least one the invention further education variant is an automatic production the connection between the window pane and window regulator allow without the need for assembly work by a worker are necessary.

According to the invention, the object is achieved by a device the features of claim 1 and a device solved with the features of claim 11. The subclaims indicate design variants of the invention.

The principle of the invention sees an elastic spring element with which the jaws of a device for connection a window with a window towards on the surface of a window pane can. Tensioning elements can be used to tension the spring element used with those after inserting the window pane the required clamping force between the clamping jaws can be generated.

But it is also possible to pre-tension Store disc assembly in the spring element. After this Insert the window between the jaws the clamping force is released by actuating an unlocking device, which then clamp the jaws onto the disc surface presses. This unlocking can also be done through the window pane itself, especially caused by the lower edge of the pane become.

Also stands in the constructive embodiment of the invention a variety of variants are available. For example can the jaws integral part of an in essential U-shaped disc holder to which a Process for making the connection to the mechanics of the Window lifter is molded. One also essentially U-shaped spring clip engages around the disc holder, whereby the first end with the outside of the associated clamp jaw and the second end with the outside of the other Clamping jaw is connected via a clamping element.

The connection points are preferably articulated or as Slide pair formed to the operating force when Do not increase tensioning of the device unnecessarily. Will that Clamping element, on the one hand, in the area of a clamping jaw and on the other hand in an end region of the spring clip supported, brought into its clamping position, then the Ends of the spring clip pressed apart. The most Spring element (spring clip) generated clamping force on the Transfer jaws and presses them onto the surface the window pane.

Such toggle levers are particularly suitable as tensioning elements or tensioning cams that have a stable position of their tensioning position feature. This can easily be achieved by the clamping element in the clamping position at a stop is applied and in this position the point of maximum Tension has already (slightly) exceeded. Thereby can spontaneously open the device become; also the use of separate locking means then to secure the position of the clamping element is not required.

According to a further variant, disc holders are provided, whose legs as a spring clip or (in a two-part Version) are designed as spring clips. Thereby can reduce the depth of the device, which the Trend towards narrower vehicle doors. One of the the two jaws form one free end of the disc holder, while the other end is a swivel Tensioning element carries. Again, the ends of the disc holder, which acts as a spring clip when swiveling the The clamping cam is pushed apart and so the clamping force generated. In the clamping position, it lies as a jaw trained area of the clamping cam on the window pane pressing.

The two-part version of the last described variant has a leg with an integrated jaw and molded Process on. There is also an attachment area to connect this part with the second part, the Spring clip, provided. The attachment is preferably done as a plug connection. The invention is a Device provided that is a simple Assembly for the purpose of connecting a window pane with a window regulator allowed. Solving can be just as easy the connection for service purposes. The combination too with other connection techniques, e.g. glue or making a positive connection is easy possible. The simple structure of the parts used enables an inexpensive manufacture. Usually can rational profiling, continuous casting or other on the Production of continuous semifinished processes applied become.

Figures 1 to 3e show embodiment variants of the invention using a separate spring clip that can be tensioned by a tensioning element and the thus generated Spring force via articulated support areas on the jaws transmits.

The embodiment shown in Figure 1 is used an upwardly open U-shaped disc holder 1, the upper areas facing the window pane 5 as clamping jaws 11, 12 are formed and in introductory slopes 8 leak for the window pane 5. In the area below an extension 10 adjoins the pane holder 1, the to fix the device with the mechanics of Window lifter is used. A toggle lever 4 serves as a tensioning element. He is articulated in the knee area with the associated free end of the spring clip 2 in connection. The short free end of the toggle lever 4 also bears pivotable, on the associated leg of the disc holder 1. On the opposite side of the disc holder 1 the other end of the spring clip 2 is supported directly in the Area of the jaw 11. All joints 31, 32, 33 are designed and clipped according to the ball-pan principle, so that an easy completion and handling of the Device is possible.

1, 1b, 1c the toggle lever 4 show in the clamping position is a non-braced in Figure 1a Device shown. In this position is the gap adjoining the lead-in slopes 8 between the jaws 11.12 slightly larger than that Thickness of the window pane 5. By swiveling the free End 40 of the toggle lever 4 in the direction of the window pane 5 the ends of the U-shaped spring clip 2 are spread and thereby the clamping force required for the pane attachment generated that transferred to the jaws 11,12 becomes. When the maximum clamping force is exceeded, the is present when the lever arm between the joints 32 and 33 causes the largest spread of the spring clip 2 comes the toggle lever 4 in the stable position (see Figure 1 b). A spontaneous disconnection is not expected.

A very much the embodiment described above Figures 2a to 2c represent a similar variant differs only in the construction of the Toggle lever 4a and its interaction with the lower edge the window pane 5. The free end 40a of the toggle lever 4a engages through a recess 100 in the non-tensioned state in the leg of the disc holder 1a in the inner area the disc holder. When inserting the window pane 5 enters the gap between the jaws lla, 12a Lower edge of pane engages with the free end. With progressive lowering of the window 5 is the Toggle lever 4a pivoted about pivot point 32a until it finally automatically after overcoming a dead center (Point of maximum clamping force) in the stable clamping state snapped.

This variant has the advantage of automatic attachment on. For example, the attachment during the first retraction of the window pane 5 into the sealing area be done, which has the added benefit of an ideal Disc alignment brings with it.

The embodiment shown in FIGS. 3 to 3e also provides just a modification of the design principle already described Accordingly, the outer area of the Disc holder 1b opposite the jaws llb one Connection area 1b 'with an inner projection. He is used to attach the spring clip 2b, the resilient Hook 21 in the assembled state the projection of the connection area 1b 'overlaps. On the opposite side the spring clip 2b carries an elongated recess 20 designed sliding guide, wherein the nose 4b '' of a tensioning cam 4b intervenes. Its joint area 4b 'is the joint 32c assigned.

In Figure 3c, the position of the clamping cam 4b is in the untensioned Recognizable condition. To tension the device, is the tensioning cam 4b by means of a special Auxiliary tool moved to the upper stop position where the tensioning cam 4b reaches its stable position. The tense State is shown in Figures 3, 3d and 3e.

Use the design variants of Figures 4a to 6d a design principle deviating from the forms described above: This is the task of disc holders and spring clip combined in one functional unit, i.e. the disc holder also functions as that Spring element applying clamping force (spring clip).

Figures 4a to 4c show different views of an inventive Device with a spring clip one-piece disc holder 1c. He too is essentially U-shaped and carries in its lower Area an extension 10c, with which the connection to Mechanics of the window regulator should be manufactured. One the free leg of the disc holder 1c is as a clamping jaw 11c trained. The end of the other leg forms a joint 33c, in which a bolt 330 is mounted, which in turn a tension cam 4c carries.

In the illustration in FIG. 4a, the tensioning cam 4c in the position shown in which the window 5 in the Disc holder 1c can be inserted. Here is the Window 5 facing the guide jaw 13c to the the jaw 12c extends at an angle, which one has a greater distance from the joint 33c. Both jaws 12c and 13c are in relation to each other over a curved area Connection. Is on the free end of the jaw 12c exerted an actuating force so that the clamping cam 4c with its clamping jaw 12c in the direction of the window pane 5 pivots, then the legs of the disc holder 1c spread. This elastic deformation creates the for the Necessary clamping force. Figures 4b and Figures 4c show views of the tensioned device.

Of course, the clamping cam 12c, as well as the Design the toggle lever described so that the clamping position of the tensioning cam 12c remains stable in itself. Please note ensure that the pivot axis of the joint 33c over the bearing surface the jaw 12c lies with the window pane 5 forms. The greater the distance 120 (in the direction of the disc) the pivot axis of the joint 33c from the edge 121 of the The support surface 122 of the jaw 12c is the more stable the clamping position of the clamping cam 4c.

The variant shown in FIGS. 5a to 5c differs differs from that described in FIGS. 4a to 4c Embodiment only in the two-part structure of the Disc holder 1d. Although here the number of parts of the device is increased, the benefit of using it simpler parts predominate. The leg 1d of the disc holder is relatively solid and rigid. Be The upper area acts as a jaw 11d and starts up its free end in a chamfer. It forms together with the curved transition area between the insertion jaw 13d and the jaw 12d of the clamping block 4d the lead-in chamfers 8 for the window pane 5. The lower one End of the leg 1d runs in the intended for assembly Extension 10d. The other leg of the disc holder is formed by the spring bracket ldd, the two bends wearing. Its lower free clamping end 60 is in one Spring clip 6 inserted.

A two-part construction of the disc holder shows the variant of the invention according to Figures 6a to 6d. However, it differs significantly in type and Way of generating the spring force (clamping force). While in all the above embodiments, the window pane 5 between the non-clamped jaws of the invention Device was introduced and then the actuation of a clamping element to generate the clamping force served, the clamping force is stored in the Device according to Figure 6 even before the window pane is installed 5.

For this, the dimensioning or design of the Leg le and the spring clip lee in such a way that in assembled, de-energized condition, i.e. in the spring clip holder 6 inserted clamping end 60 and not inserted window 5, the jaws 11e, 12e only free another gap that is narrower than the thickness of the window pane 5. Then between the jaws 11e, 12e of the legs 1e, 1ee a spacer 7 introduced that the legs 1e, 1ee on a Gap width spreads that is larger than the slice thickness. To stabilize the position of the spacer 7 are provided below the jaws 11e, 12e grooves 71, in the latches 70 of the spacer 7 can snap into place.

As indicated in FIG. 6a, the window pane 5 can now be inserted into the disc holder. In the further The lower edge of the pane enters with the spacer 7 engages (see Figure 6b) and finally releases this from the locking grooves 71. Reaches the spacer 7 the lower area of the disc holder (as in Figure 6c shown), then the stored spring force leads to pressing support of the jaws 11e, 12e on the surface the window pane. Because of the constructive design this variant is an unintentional release of the Connection between the pane holder and the window pane 5 excluded.
