Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer geschlossenen gewölbten Abdeckung aus mehreren Glaselementen sowie eine bevorzugte Verwendung derart hergestellter Glaselemente.The invention relates to a method for producing a closed arched Cover made of several glass elements and a preferred use of such manufactured glass elements.
Öffnungsfähige Fahrzeugdächer mit mehreren, in Fahrtrichtung hintereinander angeordneten transparenten Lamellen wurden bislang ausschließlich aus Einscheibensicherheitsglas hergestellt. Durch den Biegevorgang und den nachgeschalteten thermischen Vorspannvorgang treten bei großflächigen Lamellenteilen Wölbungstoleranzen von etwa +/-1,5 mm auf. Werden mit derartigen Toleranzen behaftete Lamellen zu einer Fläche zusammengesetzt, so entstehen an den Stoßstellen Stufen, die eine optische Akzeptanz des Lamellendaches erschweren. Eine Minimierung derartigen Stoßstellen durch Zusammensuchen geeigneter Lamellen mit zueinander passenden Toleranzen würden den Herstellungsprozeß unverhältnismäßig verteuern und eine Serienfertigung unmöglich machen.Openable vehicle roofs with several transparent slats arranged one behind the other in the direction of travel have so far only been made of single-pane safety glass. By the bending process and the subsequent thermal tempering process occur in large fin members curvature tolerance of about + / 1.5 mm. If slats with such tolerances are put together to form a surface, steps are created at the joints, which make it difficult to accept the slat roof visually. A minimization of such joints by searching for suitable lamellas with matching tolerances would make the manufacturing process disproportionately expensive and make series production impossible.
Es ist ferner bekannt, Verbundglasscheiben aus mehreren gewölbten und mittels einer Klebefolie zusammenlaminierten Glasscheiben, beispielsweise für Windschutzscheiben von Fahrzeugen, herzustellen (US-A-3 453 161). Aus der DE 37 44 380 C2 ist es bekannt, aus einer gewölbten Glasscheibe einen zentralen Bereich herauszuschneiden und diesen anschließend mit einer zweiten, separat geformten Scheibe zu einer Verbundglasscheibe zusammenzulaminieren. It is also known to use laminated glass panes made of several domes and one Adhesive film laminated glass panes, for example for windscreens from Vehicles to manufacture (US-A-3 453 161). From DE 37 44 380 C2 it is known from cut out a central area of a curved glass pane and this then with a second, separately shaped pane to form a laminated glass pane laminate together.
Der Erfindung liegt die Aufgabe zugrunde, ein Herstellungsverfahren zur Herstellung einer geschlossenen gewölbten Abdeckung aus mehreren Glaselementen bereitzustellen, mittels dem ein glattes bündiges Anstoßen benachbarter Glaselemente aneinander gewährleistet wird und das für eine Großserienfertigung geeignet ist. Ferner soll eine bevorzugte Verwendung derart hergestellter Glaselemente aufgezeigt werden.The invention has for its object a manufacturing method for manufacturing to provide a closed domed cover made of several glass elements, by means of which a smooth, flush abutment of adjacent glass elements is guaranteed and that is suitable for large series production. Furthermore, a preferred use of glass elements produced in this way are shown.
Die der Erfindung zugrundeliegende Aufgabe wird durch die in den Patentansprüchen 1 und 2 angegebenen Verfahrensschritte in zwei alternativen Ausgestaltungsformen gelöst. Beiden Ausgestaltungsformen gemeinsam ist der Kerngedanke, zwei etwa gleich große, jeweils die gesamte Fläche der Abdeckung einnehmende Glasscheiben zunächst zu biegen und abzukühlen und anschließend gemäß der gewünschten Größe der Glaselemente zu schneiden. Bei der ersten Ausgestaltungsform gemäß Anspruch 1 werden die beiden Glas scheiben vor dem Schneiden mittels einer dazwischenliegenden Folie aus transparentem Klebematerial zu einer Verbundglasscheibe vereinigt. Dieses Verfahren erleichtert die Handhabung beim anschließenden Schneiden.The object on which the invention is based is achieved by the method described in claims 1 and 2 specified method steps in two alternative embodiments. Common to both designs is the core idea, two roughly the same size, To bend the entire surface of the cover glass panes first and cool and then according to the desired size of the glass elements to cut. In the first embodiment according to claim 1, the two glass slices before cutting using a transparent film in between Adhesive material combined into a laminated glass pane. This procedure facilitates the Handling during the subsequent cutting.
Gemäß der zweiten Ausführungsform nach Patentanspruch 2 wird die Paarung aus beiden gebogenen und abgekühlten Glasscheiben zunächst zu Glaspärchen geschnitten, die der Größe der gewünschten Glaselemente entsprechen. Die Glaspärchen können anschließend im Salzbad chemisch vorgespannt werden, bevor sie mittels einer dazwischenliegenden Folie aus transparentem Klebematerial zu fertigen Glaselementen zusammenlaminiert werden. Durch das chemische Vorspannen haben derart hergestellte Glaselemente eine höhere Beständigkeit gegen eine Vergrößerung von Initialschädigungen ihrer Oberfläche.According to the second embodiment according to claim 2, the pairing of the two curved and cooled glass panes first cut into glass pairs, which the Correspond to the size of the desired glass elements. The glass couple can then be chemically pre-stressed in the salt bath before they are interposed Laminated film of transparent adhesive material to finished glass elements will. Due to the chemical tempering, glass elements produced in this way have one higher resistance to an increase in initial damage to its surface.
Mittels beider Verfahren lassen sich glatt aneinanderstoßende Glaselemente herstellen, die in Verbindung eine geschlossene gewölbte Abdeckung ergeben, wobei die entstehende Fläche der Abdeckung auch eine von einer Rechteckfläche abweichende Form, beispiels weise eine Trapezfläche, aufweisen kann, ohne daß dabei, wie bei herkömmlichen Verfahren, für jedes Glaselement ein eigenes Werkzeug vorgesehen sein müßte. Ebenso kann das Schneiden bei den erfindungsgemäßen Glaslamellen längs einer gekrümmten Bahn erfolgen, wobei sich ein besonders interessantes optisches Erscheinungsbild einer derartigen Abdeckung ergibt, ohne daß sich dabei zusätzliche Schwierigkeiten hinsichtlich der Toleranzen für eine bündige Abdichtung an den Stoßstellen ergeben.Both methods can be used to produce glass elements that abut each other smoothly, which in connection result in a closed domed cover, the resulting one Surface of the cover also a shape deviating from a rectangular area, for example as a trapezoidal surface, can without, as in conventional Process, a separate tool should be provided for each glass element. As well can the cutting of the glass slats according to the invention along a curved Bahn take place, whereby a particularly interesting visual appearance of a such coverage results without additional difficulties in terms of Tolerances for a flush seal at the joints result.
Die Stärke der einzelnen Glasscheiben beträgt vorteilhaft etwa 2 bis 3 mm. Für das Schneiden der Glasscheiben hat sich insbesondere das Wasserstrahlschneiden als vorteil haft erwiesen.The thickness of the individual glass panes is advantageously about 2 to 3 mm. For the Cutting the glass panes has been particularly advantageous as water jet cutting proven.
Besonders vorteilhaft lassen sich gemäß der Erfindung hergestellte Glaselemente als Lamellen eines öffnungsfähigen Fahrzeugdaches verwenden. Hier kommt es nämlich durch die benachbarten glatten Blechflächen insbesondere auf ein glattflächiges Aussehen eines derartigen Fahrzeugdaches an, das von den Fachleuten als "flush-glazing" bezeichnet wird.Glass elements produced according to the invention are particularly advantageous as Use slats on an openable vehicle roof. Here it comes through the adjacent smooth sheet metal surfaces in particular to a smooth surface appearance such vehicle roofs, which experts call "flush-glazing".
Nachfolgend werden Ausführungsbeispiele für die Erfindung anhand der Zeichnungen beschrieben. Es zeigt:Exemplary embodiments of the invention are described below with reference to the drawings described. It shows:
Fig. 1 eine Verbundglasscheibe in ungeschnittenem Zustand, Fig. 1 is a laminated glass pane in uncut state,
Fig. 2 einen Teilquerschnitt durch die Verbundglasscheibe aus Fig. 1, Fig. 2 is a partial cross section of the laminated glass sheet of FIG. 1,
Fig. 3 eine fertige Abdeckung aus mehreren Glaselementen und Fig. 3 shows a finished cover from several glass elements and
Fig. 4 eine Variante zu Fig. 3. Fig. 4 shows a variant of FIG. 3.
Bei einem ersten erfindungsgemäßen Verfahren werden zwei etwa gleich große, jeweils die gesamte Fläche einer Abdeckung 1 einnehmende Glasscheiben 2, 3 in einer nicht darge stellten Biegeform entsprechend der späteren gewünschten Kontur gebogen und anschließend abgekühlt. Anschließend werden beide Glasscheiben 2, 3 mittels einer dazwischenliegenden Folie 4 aus transparentem Klebematerial, wie Polyvinylbutyral (PVB) in an sich bekannter Weise zu einer Verbundglasscheibe zusammenlaminiert. Anschließend wird diese Verbundglasscheibe entsprechend der Größe der gewünschen Glaselemente 11, 12, 13, 14, 15, 16 (Fig. 3) mittels einer nicht dargestellten Wasserstrahl- Schneideinrichtung geschnitten. Dadurch, daß die große Verbundglasscheibe keine inneren Spannungen aufweist, ergibt sich nach dem Schneiden ein guter glatter Übergang von einem Glaselement zum benachbarten. In a first method according to the invention, two glass panes 2 , 3 of approximately the same size, each occupying the entire surface of a cover 1 , are bent in a bending shape (not shown ) in accordance with the later desired contour and then cooled. Then both glass panes 2 , 3 are laminated together in a manner known per se to form a laminated glass pane by means of an intermediate film 4 made of transparent adhesive material such as polyvinyl butyral (PVB). This laminated glass pane is then cut according to the size of the desired glass elements 11 , 12 , 13 , 14 , 15 , 16 ( FIG. 3) by means of a water jet cutting device, not shown. The fact that the large laminated glass pane has no internal stresses results in a good smooth transition from one glass element to the adjacent one after cutting.
Wie in Fig. 4 gezeigt, ermöglicht das erfindungsgemäße Verfahren auch eine einfache Her stellung von Glaselementen 21, 22, 23, 24, die in ihrer Gesamtheit eine gewölbte Abdeckung mit nicht parallelen Begrenzungslinien ergeben. So kann die gesamte Abdeckung eine Trapezform (Fig. 4) einnehmen und die Schnittlinien zwischen den einzelnen Glaselementen 21, 22, 23, 24 können einen Radius oder eine andere beliebig gekrümmte Form aufweisen.As shown in Fig. 4, the method according to the invention also enables a simple manufacture of glass elements 21 , 22 , 23 , 24 , which in their entirety result in a curved cover with non-parallel boundary lines. For example, the entire cover can assume a trapezoidal shape ( FIG. 4) and the cutting lines between the individual glass elements 21 , 22 , 23 , 24 can have a radius or any other curved shape.
Bei einem alternativen Herstellungsverfahren werden die beiden Glasscheiben 2, 3 zunächst ebenfalls entsprechend der späteren gewünschten Kontur der Abdeckung gebogen und abgekühlt, worauf sich im Unterschied zum ersten Herstellungsverfahren unmittelbar das Schneiden der Paarung aus beiden Glasscheiben 2, 3 zu Glaspärchen anschließt, die der Größe der gewünschten Glaselemente 11, 12, 13, 14, 15, 16; 21, 22, 23, 24 entsprechen. Diese Glaspärchen können anschließend im Salzbad chemisch vorgespannt und anschließend mittels einer jeweils dazwischengelegten Folie 4 aus transparentem Klebematerial, wie Polyvinylbutyral (PVB) zusammenlaminiert werden. Die beim Vorspannen sich in den Randschichten der Scheibe aufbauenden Druckspannungen wirken einer Vergrößerung von Initialschäden, wie Kratzern an der Oberfläche der Scheiben bzw. Glaselemente entgegen.In an alternative manufacturing process, the two glass panes 2 , 3 are initially also bent and cooled in accordance with the later desired contour of the cover, whereupon, in contrast to the first manufacturing process, the pairing of the two glass panes 2 , 3 is immediately cut into pairs of glass which are the size of the desired glass elements 11 , 12 , 13 , 14 , 15 , 16 ; 21 , 22 , 23 , 24 correspond. These glass pairs can then be chemically tempered in the salt bath and then laminated together using a film 4 of transparent adhesive material, such as polyvinyl butyral (PVB), which is interposed in each case. The compressive stresses that build up in the edge layers of the pane during tempering counteract an increase in initial damage, such as scratches on the surface of the pane or glass elements.
In beiden Fällen ergibt sich ein Verbund von Glaselementen zu einer Abdeckung, der ein glattflächiges Erscheinungsbild bietet und keinerlei Stufen an den Stoßstellen der einzelnen Glaselemente aufweist. Ein derartiger Verbund ist besonders vorteilhaft für eine Verwendung als Lamellendach eines Fahrzeuges geeignet. Für diesen Verwendungszweck werden die einzelnen Glaselemente (Lamellen) in ihren Außenbereichen an der Unter seite mit Befestigungsmitteln versehen, an denen entsprechende Betätigungsmittel für das Ausstellen und Verschieben der einzelnen Lamellen angelenkt werden. Eine geeignete Mechanik für das Ausstellen beziehungsweise Verschieben solcher Glaslamellen ist beispielsweise aus der DE-A1-41 23 229 bekannt. Das Verfahren ist auch für eine Herstellung anderer bündig aneinanderstoßender Glasteile geeignet, insbesondere wenn diese eine Wölbung aufweisen, wie beispielsweise Gebäudeverglasungen oder Verglasungen an Fahrzeugen mit festen und beweglichen Elementen.In both cases there is a combination of glass elements to form a cover, the one offers a smooth appearance and no steps at the joints of the individual glass elements. Such a composite is particularly advantageous for one Suitable as a lamella roof of a vehicle. For this purpose the individual glass elements (slats) in their outer areas on the lower Side provided with fasteners on which appropriate actuating means for the Issuing and moving the individual slats are articulated. A suitable one Mechanism for the issuing or moving of such glass slats is known for example from DE-A1-41 23 229. The procedure is also for one Production of other flush glass parts suitable, especially if these have a curvature, such as building glazing or Glazing on vehicles with fixed and movable elements.
