ROOF COVER FOR A VEHICLE AND ASSOCIATED METHOD OF MANUFACTURE
The present invention relates to a lid for
Closing an opening of a vehicle, in particular a roof opening, which has a disc, and a method for producing such a lid.
From DE 196 37 793 Cl a cover for a vehicle roof for closing a roof opening in a fixed roof surface of the vehicle is known. The lid has a cover plate and a foamed plastic element, in which
at least one reinforcing element and / or a
Fastener is foamed. There is to
Reduction of the relatively expensive foaming material at least one filler in the plastic element with foamed.
From DE 103 31 270 AI a lid for an opening in a roof surface of a vehicle is also known. The lid has a glass pane in the edge area
at least over a part of the circumference is provided at least on its underside with a foam. At the
Disk centering edge of the foam is between the bottom of the disk and the foam one
Undercut formed which extends at least 3 mm in the foam inside.
From US 2007/0040416 AI also a glass element is known, which has a peripheral frame or peripheral elements, which consist of a plastic and to the
Glass element to be injected. The peripheral frame or the Circumferential elements have at least one reinforcing element for the glass element, wherein the reinforcing element with the peripheral frame or the peripheral elements through the
encapsulating plastic is connected.
According to current market trends, ever thinner slices, for example less than 5 mm, are being developed, for example by weight, costs and / or resources
save. While the foaming sufficiently thicker
Slices usually has no discernible negative consequences for the disc, the foaming of thin discs, however, is fraught with difficulties. To foam a pane with a suitable material, for example
Polyurethane (PU), high temperatures are necessary, which lead to a shrinkage of the material used during cooling. Due to the shrinkage of the foam, so-called shrinkage forces occur, which lead to stresses within the disk, since the material foams used have a very good adhesion to the disk. Another disadvantage arises from the fact that the shrinking forces act on the disc, for example in the form of tensile forces, which leads to deformations on the surface of the disc. These result in a negative reflection optics and can even lead to the breakage of the disc.
It is an object of the present invention to describe improved apparatus and methods that allow foaming of thin slices while avoiding or reducing stresses and / or deformations of the slab.
According to a first aspect of the invention, a lid for closing an opening of a vehicle, in particular a roof opening, is described. The lid has a Disc, an adhesive element and at least one
Reinforcement element on. The disc is provided in the edge region with at least one foam. The foam surrounds at least partially the at least one reinforcing element and the adhesive element and connects the at least one
Reinforcement element and the adhesive element permanently fixed to the disc. The adhesive element is in an area of the
Reinforced element attached. The adhesive element interrupts and / or reduces at least in the region of
Reinforcing element adhesion between the at least one foam and the disc and / or between the at least one foam and the at least one
Reinforcing element.
The lid according to the first aspect of the invention provides that an adhesive element is arranged in the region of the reinforcing element within the foam surrounding the pane. The adhesive element interrupts the very good adhesion of the disc and the foam. The introduction of the adhesive element ensures that the adhesion between the plastic foam and the reinforcing element or the adhesion between the Kunststoffumschäumung and the disc in the region of the reinforcing element is interrupted. As a result, shrinking forces are not transmitted to the disk, resulting in no deformation and associated disadvantages.
According to one possible embodiment of the invention, the adhesive element, which may be, for example, an adhesive tape, an adhesive film or an adhesive label, is arranged between the disk and the at least one foam casing. The pane may be, for example, a glass pane. A first side of the adhesive member is at the reinforcing member glued surface facing the disc, wherein the second side of the adhesive member, the adhesion between the
Foaming and the disc at least reduced and / or interrupts.
The adhesive element is attached to the disk in the area of the reinforcing element, since the largest shrinkage forces act in this area. Due to the broken adhesion of the foam with the disk, no shrinkage forces can be transmitted to the disk in this region of the adhesive element. As a result, the described, disadvantageous
Effects avoided.
According to a further alternative embodiment of the
Invention is the adhesive element between the
Reinforcing element and the foam arranged. The first side of the adhesive element is at the disc
facing surface of the at least one
Glued reinforcing element. The second side of the
Adhesive element interrupts or at least reduces the
Adhesion between the foam and the at least one reinforcing element. The by the cooling at
Foaming forces produced during the foaming process and their shrinking work are not transferred to the disk, but lose their effect in the area of the partial interruption of the adhesion in the foam casing.
According to a second aspect of the invention, a method of manufacturing a lid for closing an opening of a vehicle is described. In a first step, an adhesive element with an adhesion-reducing surface is adhered to a first side of a pane. In one
another step is the disc in a foaming tool inserted. Further, a reinforcing member on the first side of the disc in a region of the adhesive member
arranged. In the next step, the disc and the reinforcing element are foamed, so that a permanent
mechanical connection between the disc and the
Reinforcing element is produced. By glued in the first step adhesive element is the transfer of shrinkage shrinkage of the foam on the disc
avoided.

1 shows a lid according to a first embodiment of the invention,
Figure 2 shows a lid according to a second
Embodiment of the invention, and Figure 3 steps of a method for producing a
generic lid. Figure 1 shows an exemplary arrangement of a lid 10 for closing a roof opening of a motor vehicle. The cover 10 has a disk 1, a foam 2 and a reinforcing element 3. Furthermore, the cover 10 has an adhesive element 20 which adheres to the pane 1 within the foam casing 2 in the region of the reinforcing element 3 with a first side 21. Furthermore, the adhesive element 20 has a second side 22 with an adhesion-reducing surface.
In the embodiment according to FIG. 1, the pane 1 has a foam casing 2, which is firmly and / or partially mechanically fixed in the edge region of the pane. The disk 1 has a thickness of 3.5 mm in the exemplary embodiment. The foam 2 consists
for example, from a Polyurethanwerktstoff. In the
Envelope 2, a V-shaped reinforcing element 3 is embedded, which consists for example of sheet steel. Next, the reinforcing element 3 by the V-shaped configuration on a cavity which is open in the direction of the disc 1. By the reinforcing element 3, the lid 10, for example, given sufficient stability to mount it, for example, in a sunroof of a vehicle. The second side 22 of the adhesive member 20 may be made of Teflon, for example.
As described at the outset, in the production process of the foam casing 2, so-called shrinkage forces arise within the foam casing 2, which are transferred to the disk 1 due to the very good adhesion of the foam casing 2 and the disk 1. Especially in the region of the cavity of the reinforcing element 3, this results in correspondingly thin disks, in particular glass panes, to stresses within the disk 1, the Deformations and / or can lead to a fraction of the disc 1 in this area.
With the second side 22 of the adhesive element 20, the adhesion between the pane 1 with the adhesive element 20 and the foam 2 is interrupted in the region of the reinforcing element. Thus, the shrinking forces or their work are not transmitted to the disc 1. The adhesive member 20 thus prevents the disc 1 deformed in the region of the reinforcing element 3 and it comes to a negative reflection optics on the surface 5 of the disc 1.
FIG. 2 shows a further cover 10 according to a second embodiment of the invention. The embodiment according to FIG. 2 substantially corresponds to the embodiment according to FIG. 1, wherein the adhesive element 20 according to FIG. 1 is not arranged between the foam 2 and the pane 1, but between the reinforcement element 3 and the foam 2. The adhesive element 20 sticks to the first one 21 at the V-shaped opening of the reinforcing element 3. By means of the second side 22, the adhesion between the foam 2 and the reinforcing element 3 is interrupted.
In the embodiment of Figure 2 is similar to the embodiment of Figure 1, a liability between the
Disc 1 and the foam 2 interrupted. In contrast to Figure 1, the adhesion is not interrupted in the transition region between the foam 2 and the disc 1, but between the foam 2 and the reinforcing element 3. The incurred during the foam-surrounding process of the foam 2
Shrinking forces are reduced or relaxed by the interrupted adhesion in the region of the adhesive element 20 in the foam 2. This will not be Transmit shrinking forces or shrinkage stresses on the disc 1, resulting in no deformation or negative optical effects on a top surface 5 of the disc 1. It thus forms a homogeneous appearance on the top 5 of the disc. 1
According to an alternative, not shown
Embodiment, the adhesive member may be, for example, an adhesive label. The adhesive label has, for example, an adhesive tape made of an acrylate adhesive as a first side and a paper surface as a second side. The foam coating adheres to the paper surface in such a way that the reduction in adhesion described above with reference to FIGS. 1 and 2 occurs when the shrinkage forces occur either as a result of detachment of the paper surface from the adhesive tape or through
Detaching the foam can be done from the paper surface. Alternatively, the second page can be a
adhesion-reducing coating, such as Teflon have.
FIG. 3 describes an exemplary embodiment of a method for producing a cover for closing an opening of a vehicle. It is about
For example, a lid according to one of
Embodiments of Figures 1 and 2.
In step Sl, an adhesive member 20, which is a
adhesion-reducing side 22, glued on a first side of a disc 1. Further, in step S2, the disc 1 is inserted into a foaming tool. In step S3, at least one reinforcing element 3 on the first side of the pane 1 in the region of the adhesive element 20
arranged. In step S4, the disc 1 and the Reinforcement element 3 is so foamed that a permanent mechanical connection between the disc 1 and the
at least one reinforcing element 3 is produced. In step S4, the disc 1 is, for example, by means of
Polyurethane (PU) foam. These are the to his
Preparation used components to a high temperature, for example 140 ° C, heated. These components are in a molding process in a foaming tool, in which the disc 1 in step S2 and the reinforcing element 3 in
Step S3 were inserted, flushed. The disk 1 has by heating the foaming tool and the
injected components a high temperature,
For example, 90 ° C on. When removing the disc 1 from the Schäumwerkzeug the lid is cooled, for example, to a temperature of 21 ° C. Due to the high
Temperature difference shrinkage forces are generated within the produced foam. This is preferably done in the region of the reinforcing element 3, since used
Reinforcement elements 3 usually have a cavity which is open in the direction of the disc 1. By glued in step Sl adhesive element is the transfer of the
Shrinking the foam around the glass
avoided.
In further alternative, not shown
Embodiments, the steps Sl to S3 can also be performed in different order. The features of a lid set forth in the described embodiments can be implemented in various ways
