Description

The invention relates to a method for producing a windscreen for a passenger car, in particular for an open passenger car, wherein a plurality of receptacles are attached to the windscreen.

Such a method is from the DE 10 2006 023 911 A1 known.

A windscreen is used in an open passenger car (typically a convertible) or a passenger car with an open roof part (typically an open sunroof) while driving to steer the airstream so that the passengers are exposed in the passenger car only a small flow of air. The windscreen is mounted in an area above the windshield, such as the roof between the A-pillars. The windscreen is typically profiled similar to an aircraft wing and has over the vehicle width (or over the long broad side of the windscreen) a slightly convex curvature towards the front of the vehicle out.

For the duration of the trip, the windscreen is typically extended, and between trips, the windscreen is usually retracted. The wind lamella is for this purpose provided with receptacles (transducers), which are fastened to the upper part of the flow-shaping part of the wind lamella, and at the bottom are each attached to a lever. At least some of the recordings are hinged at the bottom with the respective lever to an actuator (such as an electric motor, or a hand mechanism). The windscreen can be swiveled over the seats and the levers.

The recordings are arranged distributed substantially uniformly over the width of the windscreen. Due to the curvature of the wind lamella, the positions of the receptacles on the wind lamella are thereby offset slightly over the longitudinal direction of the vehicle (or in the direction of the short longitudinal side of the wind lamella). As a result, the alignment of the windscreen relative to the horizontal is defined when pivoting the windscreen over the lever and the recordings.

However, pivoting the windscreen over the seats and the levers requires that the seats be precisely aligned with respect to the levers and the flow-shaping portions of the windscreen. In an inexact alignment, the wind blade can be tilted when pivoting, or it can even misjudged the lever mechanism.

When manufacturing a wind blade made of plastic, a wind blade can be integrally formed with recordings, such as injection molding, whereby misalignments are largely excluded. However, wind blades made of plastic are not very robust. When manufacturing the windscreen including the metal receptacles, however, the components of the windscreen must be manufactured and assembled individually.

From the DE 2006 023 911 A1 or even from the DE 2006 023 912 A1 It is known to attach the recordings in each case by means of two screws in the windscreen. However, the screw connections have a relatively large clearance, and due to manufacturing tolerances on the recordings or the remaining windscreen further alignment errors can occur.

A wind lamella, at the bottom of which shots are attached, is also from the DE 10 2007 040 158 A1 and the DE 10 2006 023 912 A1 known.

Object of the invention

The invention has for its object to provide a method for manufacturing a windscreen, with which an improved alignment accuracy of the images is achieved.

Brief description of the invention

1. a) ein Lamellenunterteil sowie mehrere Aufnahmen werden in eine Pressvorrichtung eingelegt, wobei die Aufnahmen jeweils durch Löcher des Lamellenunterteils ragen und mit einer Auskragung das Lamellenunterteil hintergreifen;
2. b) die Aufnahmen werden jeweils mittels erster Ausrichteinrichtungen der Pressvorrichtung bezüglich der Pressvorrichtung ausgerichtet und fixiert;
3. c) ein Lamellenoberteil wird auf das Lamellenunterteil aufgelegt, wobei zwischen dem Lammellenoberteil einerseits und dem Lammellenunterteil und den Aufnahmen andererseits ein Kleber aufgebracht ist, und das Lamellenoberteil wird mittels einer zweiten Ausrichteinrichtung der Pressvorrichtung bezüglich der Pressvorrichtung ausgerichtet;
4. d) das Lamellenoberteil und das Lamellenunterteil werden mit der Pressvorrichtung gegeneinander verpresst.

This object is achieved by a method of the aforementioned type, characterized by the following steps:

1. a) a lamella base and a plurality of receptacles are inserted into a pressing device, wherein the receptacles each protrude through holes in the lamella lower part and engage behind the lamellar base with a projection;
2. b) the receptacles are each aligned and fixed by means of first alignment devices of the pressing device with respect to the pressing device;
3. c) a lamella upper part is placed on the lower plate part, wherein between the Lammellenoberteil on the one hand and the Lammellenunterteil and the receptacles on the other hand, an adhesive is applied, and the fin upper part is aligned by means of a second alignment of the pressing device with respect to the pressing device;
4. d) the upper plate part and the lower plate part are pressed against each other with the pressing device.

With the method according to the invention, receptacles (transducers) can be fastened to a wind lamella, wherein the receptacles are aligned with each other with very high accuracy. According to the invention, the recordings are glued in between a lamella upper part and a lamella lower part. The alignment of the recordings does not take place via the wind lamella (for example in the form of drill holes for screws, for example in the lamella upper part), but rather through the first alignment devices, which are each fixedly (and precisely positioned) to a pressing device.

As a result, manufacturing tolerances in the upper part of the slat, lower part of the slat and also in the region of the projection of the receptacles play no role for the mutual alignment of the receptacles. The fixed positioning of the first alignment devices on the pressing device results in a well-defined and exact alignment of the images with each other.

In the pressing device and the lower plate part and the upper plate part are inserted. When pressing the upper part of the slat and lower part of the slat, the seats can be held by the first alignment devices. Through the adhesive, the lower plate part and the receptacles are connected to the upper plate part. The recordings between the upper plate part and the lower plate part are largely freely movable before curing of the adhesive, so that manufacturing errors in the upper plate part or lower plate part do not affect the positioning of the recordings.

The first alignment devices preferably grip the receptacles in the same manner as the swing mechanism in the passenger car does in the assembled state. The recordings are taken, for example, from the same side of the axle holes, as do the levers of the swivel mechanism in the assembled state on the vehicle. This further minimizes alignment errors.

The inventive, exact alignment of the images with each other during the bonding process allows correct alignment of the mounted windscreen when pivoting the windscreen, in particular via lever, and reliably avoids tilting of the lever mechanism during pivoting of the mounted windscreen.

Preferred variants of the invention

Preferred is a variant of the method according to the invention, in which in step a) the lower plate part is applied to at least one contact element of the pressing device, in particular a centering pin. As a result, the orientation of the wind lamella lower part to the pressing device - and thus also to the recordings - can be improved. The pressing device typically also has, as a support, a negative relief of the lower plate part (or a part of the lower plate part) in which the lower plate part is inserted.

Also preferred is a variant of the method which provides that in step a) further two cap parts are inserted laterally of the lower plate part or laterally on the lower plate part in the pressing device, and that in step c) also between the upper plate part and the cap parts adhesive is applied. The cap parts can be designed, in particular, with attachment means for the wind lamella, such as eyelets or pins, with which the wind lamella on the vehicle can additionally be secured laterally, in particular in a retracted state. The variant allows easy integration of the cap parts in the manufacturing process of the windscreen. It is preferably provided that in step b) the two cap parts are each aligned and fixed relative to the pressing device by means of third alignment devices of the pressing device. As a result, the alignment accuracy of the cap parts is improved to the recordings, and thereby the lateral securing more precise.

In an advantageous variant, adhesive is applied in step c) on the side of the upper part of the slat facing the lower part of the slat. At the fin upper part, the application of the adhesive is particularly simple, since in the upper part of the recordings are not used. By means of the upper part can easily be connected to each other components of the windscreen. Preferably, adhesive is applied exclusively on the lamella upper part.

Very particular preference is given to a method variant in which in each case two clamping jaws of a respective first alignment device are moved in parallel against each other in step b) and clamped with a respective receptacle. By the same method a repeatable, exact alignment of the respective recording in the direction of travel (clamping direction) of the clamping jaws is achieved. The jaws center the respective recordings on the desired position relative to the pressing device. The jaws are typically moved parallel to the long broad side of the windscreen.

A preferred development of this variant provides that a common eccentric of the respective first alignment device is used for moving the respective two clamping jaws,
in particular wherein the common eccentric has two mutually opposite eccentric cam recesses, in each of which a clamping jaw or a clamping jaw holder of a clamping jaw engages, and the jaws or jaw holders are guided in a straight rail. By means of the common eccentric, the movement of the clamping jaws can be coordinated in a simple manner. The eccentric is typically rotated about an axis for clamping and relaxing the jaws via a hand lever. It is also a motorized operation of the eccentric possible.

In another development, it is provided that during clamping, the respective clamping jaws engage with extensions in one or more axle bores of the respective receptacle. The engaging projections allow the images to be aligned with respect to two further, independent directions. In particular, the extensions may taper to their respective forward end to facilitate alignment. As an alternative to one or more axle bores, the extensions can also engage in other counter recesses or on other counter edges of the receptacles.

In this further development, it is possible that the respective two clamping jaws engage with their extensions from the inside into two opposite axial bores of the respective receptacle and when clamping the jaws are spread. This intervention is useful when a lever is inserted between the two axle bores on the assembled windscreen; the aligned state then corresponds very well to the mounted state.

Alternatively, it is possible that the respective two clamping jaws engage with their extensions from the outside into one or more axial bores of the respective receptacle and when clamping the clamping jaws are contracted. This intervention is useful if, with the windscreen mounted, a lever like a fork surrounds the one or more axle bores; The aligned state then again corresponds very closely to the mounted state.

Also advantageous is a method variant in which, in step c), for aligning the upper part of the slat, it is inserted between two spring-loaded, lateral stops of the second alignment device. The spring-loaded stops provide a simple way for a quick and automatic alignment or centering of the upper plate part, typically in the direction parallel to the long broad side of the windscreen. The stops preferably also form further contact edges, which allow an alignment in the direction parallel to the short longitudinal side of the windscreen.

The scope of the present invention also includes a wind lamella produced by a method according to the invention described above. In a wind blade according to the invention a very precise alignment of the images with each other and also to the lower plate part and fin upper part is possible.

Also within the scope of the present invention is the use of a windscreen according to the invention on a passenger car, in particular on an open passenger car, wherein the windscreen is fastened in an area on the upper edge of the windscreen by means of the recordings and retractable.

Further advantages of the invention will become apparent from the description and the drawings. Likewise, according to the invention, the above-mentioned features and those which are still further developed can each be used individually for themselves or for a plurality of combinations of any kind. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.

In the context of the invention, the wind lamella comprises at least one lamella base, a lamella upper part and a plurality of receptacles, and at least these components are assembled in the context of the invention.

The sequence of figures 2a to 2d illustrates the assembly process of a windscreen in the context of the invention using the example of the windscreen of 1a ,

2a shows a pressing device 20 , in which the windscreen is inserted and in which the windscreen is to be glued; in 2a is not inserted yet a component of the windscreen.

The pressing device 20 includes a base plate 21 , on the four first alignment devices 22 (for the here four shots of the windscreen) are attached. From the first alignment devices 22 are in 2a only the hand-operated tension levers 23 visible, noticeable. Furthermore, the pressing device forms 20 a support surface 24 in their form in a central part (cf the two steps in the bearing surface 24 ) approximately corresponds to the shape of the slat lower part to be raised ("negative relief"). The bearing surface 24 is with four bushings 24a equipped, through which the shots down to the first alignment devices 22 can protrude. Left and right outside of the pressing device 20 are spring-loaded stops 25 trained (see 5a . 5b) ,

The base plate 21 is also with here three tie rods 26 provided with which a cover plate can be clamped (see. 2d) ,

In the pressing device 20 then first the lamella base 1 and then the recordings (transducers) 3 and the cap parts 6 inserted. 2 B shows accordingly the pressing device 20 with inserted lamella base 1 , inlaid recordings 3 and inserted cap parts 6 ,

In the 2 B invisible lower areas of the shots 3 be by means of the first alignment devices 22 clamped, cf. the clamping lever located in the locking position 23 (on the function of the first alignment devices 22 see. the 3 . 4a . 4b) , This will make the recordings 3 all exactly with respect to the pressing device 20 - and thus also exactly with each other - aligned. The clamped state is maintained for the subsequent bonding process.

The slat base 1 lies with his score 11 on a centering pin 27 the pressing device 20 to a central position of the lamella base 1 on the curved pad 24 to obtain. If desired, the lamellar base can 1 be additionally aligned and / or fixed by other facilities.

The cap parts 6 be on the lamella base 1 placed on the edge, with a rough mutual alignment on the profiles of the lower plate part 1 and the cap parts 6 he follows. For a more accurate alignment and fixation of the cap parts 6 not shown third aligning devices can be used, such as terminals.

Subsequently, the lamella upper part 8th applied, cf. 2c with overlaid lamella upper part 8th , In the example presented above was previously on the underside of the lamella upper part 8th an adhesive is applied in a defined manner (typically limited to a few, selected points, but at least to all recordings 3 , all cap parts 6 and in several places opposite the uncovered lamellar base 1 ).

The launched lamella upper part 8th is in the pressing device 20 by means of second alignment devices 28 aligned. In the exemplary embodiment shown, the second alignment devices comprise 28 two spring-loaded stops 25 , which the lamella upper part 8th concerning the direction of the long broadside LB in the center of the pressing device 20 align. In addition, for example, terminals may be provided which the lamella upper part 8th also in the direction of the short longitudinal side KL Align (not shown).

Subsequently, the lamella upper part 8th against the slat base 1 pressed ("pressed to measure"). This is a cover plate 29 on the tension pins 26 put on, and the cover plate 29 gets on the base plate 21 (or the edition 24 ) is pulled or pressed, cf. 2d , In the example shown to locking pins 30 in the dowel pins 26 inserted. About stakeout is the exact distance between the base plate and the cover plate 29 specified. At the (in 2d not visible) underside of the cover plate 29 is preferably a negative relief of the top of the fin top 8th educated.

The cover plate 29 remains so long tightened or pressed against the base plate posititoniert until the adhesive has cured. Then the locking bolts 30 removed, the cover plate 29 removed the tension levers 23 dissolved and the finished wind blade are removed. Subsequently, in the pressing device 20 the components of another windscreen to be mounted are inserted and glued.

3 illustrates a first alignment device based on an eccentric 31 , which can be used in the context of the invention (see also 2a , Bzz. 22).

By means of a clamping lever 23 can the rotatably mounted eccentric 31 an eccentric thing EA to be turned around. In the eccentric 31 are two (with respect to the eccentric axis EA ) Opposite Exzenterausnehmungen 33a . 33b educated. The eccentric recesses 33a . 33b have a substantially constant width, but over its extension varying radial distance from the eccentric axis EA ,

A first jaw holder 35a is with a pen 34 formed in the Exzenterausnehmung 33a intervenes. The first jaw holder 35a is in an in 3 not shown guide (such as a rail) held in the jaw holder 35a (in 3 ) only to the left and right (see guide direction FR ) can be moved. Accordingly, a second jaw holder for the second Exzenterausnehmung 33b provided (indicated only by the central screw 36 of the jaw holder in 3 ).

Will the cocking lever 23 now to the right RE pivoted, the eccentric rotates 31 counterclockwise with. The pencil 34 or the first jaw holder 35a is doing by means of Exzenterausnehmung 33a closer to the eccentric axis EA led to the right. Accordingly, a first jaw 37a that in the first jaw holder 35a is held, moved to the right. At the same time, the second clamping jaw holder and a corresponding second clamping jaw are compared in parallel, in this case, to the left on the eccentric axis EA to, guided (not shown), so that the jaws are contracted. During a movement of the clamping lever 23 Back to the left, the jaws would be spread again.

The 4a and 4b illustrate the access of the jaws to a receptacle 3 ,

The jaw holders 35a . 35b are in a rail 38 guided. At each jaw holder 35a . 35b is a jaw 37a . 37b formed, each having an extension 39a . 39b having.

In 4a are the jaws 37a . 37b in a splayed position, in which the appendages 39a . 39b each in axial bores (In 4a hidden) of the tabs 12a . 12b the recording 3 intervene from the inside and the recording 3 so jam.

In 4b are the jaws 37a . 37b in a contracted position, in which the appendages 39a . 39b from the axle holes of the tabs 12a . 12b are withdrawn. The recording 3 is free.

Because the jaws 37a . 37b to be moved in parallel, is the recording 3 with respect to the inner edges of the tabs 12a . 12b always kept centered in the tensioned state, even if the distance between the inner edges (for example due to manufacturing tolerances) varies. The jaws 37a . 37b take part in the recording 3 in a similar way as a lever between the tabs 12a . 12b arranged and hinged via a bearing pin, so that a mismatch of the mounted windscreen is excluded with respect to the vehicle-side lever during assembly of the windscreen on the vehicle.

The 5a and 5b illustrate a spring-loaded stop 25 for the centering of a lamella upper part 8th in the context of the invention.

The field-loaded stop 25 is in the direction of the long broadside LB slidable on the pressing device 20 stored. A shift to the outside (in 5a and 5b to the left) he sits down with the force of a compression spring 40 opposite; the compression spring 40 is here on one at the pressing device 20 immovable bolt stored.

At the spring-loaded stop 25 are in the example shown a contact edge 41 as well as two longitudinal notches 42 trained (cf. 5a) at which the lamella upper part 8th can be clamped (cf. 5b) ,

By a symmetrical design of the spring-loaded stops 25 on both sides of the pressing device 20 (see. 2a) , especially with equally strong compression springs 40 , the lamella shell becomes 8th through the spring-loaded stops 25 in the direction of the long broadside LB always centered in the pressing device 20 aligned.
