Description
Technical Field
The present invention relates to a covering for closing an opening, in particular a roof opening, in a vehicle, said covering having a pane, and to a method for manufacturing such a covering.
Background
DE19637793C1 discloses a cover for a vehicle roof for closing a roof opening in a fixed roof surface of a vehicle. The covering element has a covering panel and a plastic element foamed thereon, into which at least one reinforcing element and/or fastening element is foamed. At least one filling is foam-molded simultaneously into the plastic element in order to reduce the relatively expensive foaming material there.
DE10331270a1 also discloses a cover for an opening in the roof surface of a vehicle. The cover has a glass pane, at least the underside of which is provided with a foam coating in a border area over at least part of the circumference. At the foam cladding boundary towards the centre of the pane, an undercut is formed between the underside of the pane and the foam cladding, said undercut extending at least 3mm into the foam cladding.
US2007/0040416a1 also discloses a glass element having a perimeter frame or perimeter element formed of plastic and injection molded around the glass element. The perimeter frame or the perimeter element has at least one stiffening element for the glass element, wherein the stiffening element is connected adjacent to the perimeter frame or the perimeter element by injection-molded plastic.
According to current market trends, as thin panes as possible, e.g. less than 5mm, are becoming mature, e.g. in order to save weight, cost and/or resources. Foam coating a sufficiently thick pane generally does not have any significant negative effect on the pane, however, foam coating a thin pane is problematic. For the covering of the pane with a suitable material, for example a foam of Polyurethane (PU), high temperatures are required, which on cooling cause shrinkage of the material used. Since the material used, the foam coating, is very easily bonded to the glass pane, the shrinkage of the foam coating results in so-called shrinkage forces which cause stresses in the pane. Another drawback consists in that the shrinking forces act on the pane, for example in the form of tensile forces, thus causing deformations on the surface of the pane. The deformation leads to unfavorable reflective optical properties and may even crack the pane.
SUMMERY OF THE UTILITY MODEL
It is an object of the present invention to describe an improved apparatus and method that allows for the cladding of thin panes with foam and in the process avoids or reduces the stress and/or deformation of the pane.
According to a first aspect of the invention, a cover for closing an opening in a vehicle, in particular a roof opening, is described. The cover has a pane, an adhesive element and at least one reinforcing element. The pane is provided with at least one foam coating in the border area. The foam blanket at least partially surrounds the at least one reinforcing element and the adhesive element and permanently fixedly connects the at least one reinforcing element and the adhesive element to the pane. The adhesive element is fixed in the region of the reinforcing element. The adhesive element interrupts and/or reduces the adhesion between the at least one foam layer and the pane and/or between the at least one foam layer and the at least one reinforcing element at least in the region of the reinforcing element.
According to a first aspect of the invention, the covering has the adhesive element arranged in the area of the reinforcing element within the foam covering of the pane. The adhesive element interrupts the very good adhesion of the pane and the foam covering. The embedding of the adhesive element ensures that the adhesion between the plastic foam layer and the reinforcing element and/or the adhesion between the plastic foam layer and the pane is interrupted in the region of the reinforcing element. Thus, the shrinking forces are not transmitted to the pane and thus no deformations and disadvantages associated therewith are created.
According to a possible development of the invention, an adhesive element, which may be, for example, an adhesive tape, an adhesive film or an adhesive label, is arranged between the pane and the at least one foam coating. The pane may be, for example, a glass pane. The first side of the adhesive element adheres to that surface of the pane which faces the reinforcing element, while the second side of the adhesive element at least reduces and/or interrupts the adhesion between the foam covering and the pane.
The adhesive element is fitted to the pane in the region of the reinforcing element, since the greatest contraction force acts in this region. By means of the interrupted adhesion of the foam covering to the pane, the shrinking forces cannot be transmitted to the pane in this region of the adhesive element. This avoids the described adverse effects.
According to a further alternative refinement of the invention, the adhesive element is arranged between the reinforcing element and the foam skin. In this case, the first side of the adhesive element is affixed to that surface of the at least one stiffening element which faces the pane. The second side of the adhesive element interrupts or at least reduces the adhesion between the foam skin and the at least one stiffening element. The shrinkage forces due to cooling during foaming and the shrinkage work of said shrinkage forces are not transmitted to the pane, but rather their effect disappears in the area of the foam covering where the bonding is partially interrupted.
According to a second aspect of the invention, a method for manufacturing a cover for closing an opening in a vehicle is described. In a first step, the adhesive element is affixed to the first side of the pane by an adhesive surface. In a further step, the pane is placed in a foaming device. In addition, a reinforcing element is arranged in the region of the adhesive element on the first side of the pane. In a next step, the pane and the stiffening element are coated with foam, thereby creating a permanent mechanical connection between the pane and the stiffening element. By means of the adhesive element applied in the first step, it is avoided that the shrinkage of the foam encapsulation is transferred to the pane.
Further advantageous refinements of the invention are disclosed in the following detailed description of exemplary embodiments.
Drawings
The invention is described below by way of exemplary embodiments and with reference to the accompanying drawings. In the drawings, like components of the different exemplary embodiments are denoted by like reference numerals.
In the drawings:
figure 1 shows a cover according to a first exemplary embodiment of the invention,
fig. 2 shows a cover according to a second exemplary embodiment of the invention, an
Fig. 3 shows the steps of a method for producing a cover of the type described.
Detailed Description
Fig. 1 shows by way of example an arrangement of a cover 10 for closing a roof opening in a motor vehicle. The cover 10 has a pane 1, a foam covering 2 and a reinforcing element 3. In addition, the cover 10 has an adhesive element 20, which adhesive element 20 is affixed to the pane 1 in the area of the reinforcing element 3 within the foam layer 2 by means of the first side 21. In addition, the adhesive element 20 has a second side 22 with a viscosity-reducing surface.
In a modification according to fig. 1, the pane 1 has a foam coating 2, which foam coating 2 is connected to the pane in the border region of the pane mechanically fixedly over the entire periphery and/or over part of the periphery of the pane. In this exemplary embodiment, pane 1 is 3.5mm thick. The foam layer 2 is made of a polyurethane material, for example. A V-shaped reinforcing element 3, for example made of steel plate, is embedded in the foam skin 2. In addition, the V-shaped configuration provides the reinforcing element 3 with a cavity open towards the pane 1. The reinforcing element 3 provides, for example, sufficient stability for the cover 10 in order to mount the cover, for example, in a sliding roof of a vehicle. The second side 22 of the adhesive element 20 may be constructed of teflon, for example.
As mentioned at the outset, during the production of the foam cladding 2, so-called shrinkage forces occur in the foam cladding 2, which are transmitted to the pane 1 due to the very good adhesion between the foam cladding 2 and the pane 1. In particular in the region of the cavity of the reinforcing element 3, this leads to stresses in the pane 1 in the case of correspondingly thin panes, in particular glass panes, with the result that deformations occur in this region and/or cracks may occur in the pane 1.
By means of the second side 22 of the adhesive element 20, the pane 1 is interrupted in the region of the stiffening element by means of the adhesion between the adhesive element 20 and the foam covering 2. Therefore, the shrinking forces and the shrinking work are not transmitted to pane 1. The adhesive element 20 thus prevents the pane 1 from deforming in the region of the stiffening element 3 and from producing disadvantageous reflective optical properties at the upper side 5 of the pane 1.
Fig. 2 shows a further covering element 10 according to a second embodiment of the invention. The configuration according to fig. 2 substantially corresponds to the configuration according to fig. 1, wherein the adhesive element 20 according to fig. 1 is arranged not between the foam covering 2 and the pane 1, but between the reinforcing element 3 and the foam covering 2. The adhesive element 20 is affixed to the V-shaped opening of the reinforcing element 3 by the first side 21. The adhesion between the foam coating 2 and the reinforcing element 3 is interrupted by means of the second side 22.
In the exemplary embodiment according to fig. 2, the adhesion between pane 1 and foam covering 2 is interrupted in a similar manner as in the exemplary embodiment according to fig. 1. In contrast to fig. 1, the adhesive bond is not interrupted in the transition region between the foam coating 2 and the pane 1, but between the foam coating 2 and the reinforcing element 3. In the region of the adhesive elements 20 in the foam skin 2, the shrinkage forces occurring during the foaming of the foam skin 2 are dissipated or reduced by the interrupted adhesive bond. In this way, the shrinking forces and stresses are not transmitted to pane 1, and therefore there is no deformation or negative optical effect on upper side 5 of pane 1. Thus, uniform optical characteristics are formed on the upper side 5 of pane 1.
According to an alternative exemplary embodiment (not shown), the adhesive element may be, for example, an adhesive label. The adhesive label has, for example, an adhesive tape composed of an acrylate adhesive as a first side and a paper surface as a second side. The foam layer is bonded to the paper surface in the following manner: the adhesive force reduction described above with reference to fig. 1 and 2 may be performed by separating the paper surface from the adhesive tape, or may be performed by separating the foam coating from the paper surface when the contraction force is generated. Alternatively, the second side may have a viscosity-reducing coating, such as a polytetrafluoroethylene coating.
FIG. 3 depicts one exemplary embodiment of a method for manufacturing a cover for closing an opening in a vehicle. This relates, for example, to the cover according to one of the exemplary embodiments of fig. 1 and 2.
In step S1, an adhesive element 20 having a de-adhered second side 22 is affixed to the first side of pane 1. In addition, in step S2, pane 1 is placed in a foaming device. In step S3, at least one reinforcing element 3 is arranged on the first side of pane 1 in the region of bonding element 20. In step S4, pane 1 and reinforcing element 3 are coated with foam in such a way as to form a permanent mechanical connection between pane 1 and the at least one reinforcing element 3.
In step S4, pane 1 is coated, for example, with the aid of Polyurethane (PU) foam. For this purpose, the ingredients used for their manufacture are heated to high temperatures, for example 140 ℃. The composition is flushed into the foaming device during the moulding process, into which pane 1 has been placed reinforcing element 3 in step S3 in step S2. By means of the foaming device and the heating of the injected composition, pane 1 has a high temperature, for example 90 ℃. When pane 1 is removed from the foaming apparatus, the cover is cooled to a temperature of, for example, 21 ℃. The high temperature difference causes the generation of shrinkage forces in the produced foam coating. This preferably takes place in the region of the reinforcing element 3, since the reinforcing element 3 used generally has a cavity which is open in the direction of the pane 1. By means of the adhesive element affixed in step S1, the transmission of shrinkage of the foam covering to the pane is avoided.
In another alternative exemplary embodiment (not shown), steps S1-S3 may also be performed in a different order.
The cover features described in the exemplary embodiments can be combined with one another in different ways in order to achieve the advantages and/or functions mentioned in each case.
