Abstract

1. Door leaf comprising at least two rebated parts (2, 3) which are arranged on the left and right longitudinal edges, respectively, of this door leaf and which are connected to a planar central part (1) by means of dowels (20), characterized in that both the rebated parts (2, 3) and the central part (1) have a plurality of dowel holes (9, 12) introduced at equal intervals (d), the sum of the depths (t1, or t2) of the dowel holes (9 or 12) in the central part (1) and in each rebated part (2 or 3) being greater than the length of the dowels (20) inserted for connection in such a manner that sufficient depth remains for receiving the dowels (20) even upon a reduction of the width of the door leaf adapted to suit the individual use.

Description

Die Erfindung richtet sich auf ein Türblatt nach dem Oberbegriff von Anspruch 1 und ein Verfahren zu seiner Herstellung nach dem Oberbegriff von Anspruch 6.The invention relates to a door leaf according to the preamble of claim 1 and a method for its production according to the preamble of claim 6.

Herkömmlicherweise ist es üblich, industriell hergestellte Türblätter in verschiedenen Normgrößen herzustellen und vorrätig zu halten. Außerdem ist es bekannt, Türblätter der gattungsgemäßen Art handwerklich dadurch herzustellen, daß seitliche Falzteile über Dübel mit Querfriesen verbunden werden (vgl. z. B. US-A-1 939 999). Die Querfriese schließen dabei dann entweder eine geschlossene Türfüllung aus leichterem Material oder aber eine Verglasung ein. Derart handwerklich hergestellte Türen können naturgemäß in jeder beliebigen Größe gefertigt werden, sind aber bedingt durch die Herstellungstechnik relativ teuer und die Herstellung erfordert einen nicht unbeachtlichen Zeitaufwand.Traditionally, it is customary to manufacture industrially manufactured door leaves in various standard sizes and to keep them in stock. In addition, it is known to produce door leaves of the generic type by hand in that lateral folded parts are connected to cross friezes by means of dowels (cf., for example, US Pat. No. 1,939,999). The cross friezes then either include a closed door panel made of lighter material or glazing. Such handcrafted doors can of course be made in any size, but due to the manufacturing technology are relatively expensive and the production takes a considerable amount of time.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Türblatt zu schaffen, welches einerseits individuell dimensioniert werden kann, welches andererseits aber aufgrund eines hohen Maßes an Vorfertigung industriell schnell und kostengünstig herstellbar ist und ein Verfahren für eine derartige Herstellung anzugeben.Proceeding from this, the object of the invention is to create a door leaf which, on the one hand, can be individually dimensioned, but on the other hand can be manufactured industrially quickly and inexpensively due to a high degree of prefabrication, and to specify a method for such production.

Diese Aufgabe wird gelöst durch den kennzeichnenden Teil von Anspruch 1. Aufgrund der erfindungsgemäßen Lösung ist es möglich, die Falzteile in einer einheitlichen Größe in großer Stückzahl vorzufertigen. Diese Falzteile tragen an ihren Außenkanten die ein dichtes Schließen des Türblatts gewährleistenden Türfalze, wobei im Bereich dieser Türfalze an der einen Seite die Beschläge für das Türschloß und an der anderen Seite die Bandsysteme angeordnet sind. In gleicher Weise können die Türfüllungen in industriellem Maßstab vorgefertigt werden. Auch bei dieser Vorfertigung braucht auf die bauseitigen Endabmessungen keine Rücksicht genommen zu werden. Die Türblätter können dabei einstückig ausgebildet sein oder aber Querfriese aufweisen, welche entweder aus optischen Gründen z. B. mit einem in Farbe oder Maserung abweichenden Furnier versehen oder aber zur Begrenzung von Glasflächen vorgesehen sind.This object is achieved by the characterizing part of claim 1. Because of the solution according to the invention, it is possible to prefabricate the folded parts in a uniform size in large numbers. These rebated parts carry on their outer edges the door seams which ensure tight closing of the door leaf, the fittings for the door lock and the hinge systems being arranged on the one side in the region of these door seams. In the same way, the door panels can be prefabricated on an industrial scale. In this prefabrication, too, no attention needs to be paid to the final dimensions on site. The door leaves can be formed in one piece or have cross friezes which either for optical reasons z. B. provided with a different color or grain veneer or are provided to limit glass surfaces.

Das Mittelteil und die Falzteile sind mittels Dübeln miteinander verbunden. Um unabhängig vom späteren Vorsehen einer durchgehenden Füllung oder von Querfriesen in bestimmten Höhenlagen eine Vorfertigung zu ermöglichen, sind in den Falzteilen in relativ kurzen, äquidistanten Abständen Dübelbohrungen eingebracht, in welche lediglich bei Bedarf Dübel eingesteckt werden, um aufgrund dieser Dübel eine Verbindung der Querfriese mit dem in beliebiger Weise aufgebauten Mittelteil zu ermöglichen.The middle part and the folded parts are connected to each other by means of dowels. In order to enable prefabrication regardless of the subsequent provision of a continuous filling or of cross friezes at certain altitudes, dowel holes are made in the rebate parts at relatively short, equidistant intervals, into which dowels are only inserted if necessary, in order to connect the cross frieze with these dowels to enable the middle section constructed in any way.

Die Tiefe der Dübelbohrungen im Mittelteil bzw. in den das Mittelteil aufbauenden Teilen ist so gewählt, daß auch bei einer auf den individuellen Anwendungsfall angepaßten Verkürzung der Breite des Türblatts eine ausreichende Tiefe zur Aufnahme der Dübel verbleibt.The depth of the dowel holes in the middle part or in the parts making up the middle part is chosen so that even with a shortening of the width of the door leaf adapted to the individual application, a sufficient depth remains for receiving the dowels.

Aus dem Vorstehenden ergibt sich, daß sich eine derartige Tür aus relativ wenigen, hochgradig vorfabrizierten Teilen in einfachster Weise ohne Fachkräfte montieren läßt. Darüber hinaus zeigt die erfindungsgemäße Konstruktion eine ganz charakteristische ästhetische Wirkung, welche sich aus der Kombination des Mittelteils mit den senkrecht längs derselben verlaufenden Falzteilen ergibt. Zur Erzielung besonderer ästhetischer Wirkungen und um Bauherrn bzw. Architekten trotz der industriellen Fertigung einen möglichst großen individuellen Gestaltungsfreiraum zu lassen kann z. B, vorgesehen werden, daß die Falzteile ein farblich identisches Furnier wie das Mittelteil oder aber farblich abweichende Furniere bzw. eine in ihrem Verlauf abweichende Maserung aufweisen. Dies macht deutlich, daß ausgehend von einer überschaubaren Zahl von vorzufertigenden Grundelementen eine außerordentlich hohe Zahl von Kombinationen mit einer jeweils unterschiedlichen ästhetischen Wirkung denkbar ist.From the above it follows that such a door can be assembled from relatively few, highly prefabricated parts in the simplest way without specialists. In addition, the construction according to the invention shows a very characteristic aesthetic effect, which results from the combination of the middle part with the fold parts running perpendicularly along the same. To achieve special aesthetic effects and to give clients or architects as much individual design freedom as possible despite the industrial production. B, it can be provided that the folded parts have a color-identical veneer as the middle part or color-different veneers or a different grain in their course. This makes it clear that, based on a manageable number of basic elements to be prefabricated, an extraordinarily high number of combinations with a different aesthetic effect is conceivable.

Eine besonders leichte und kostengünstig realisierbare Konstruktion gibt Anspruch 2 an.Claim 2 specifies a particularly light and inexpensive construction.

Für den Fall, daß eine durchgehend ausgebildetes Mittelteil gewünscht wird, erscheint die Ausgestaltung nach Anspruch 3 günstig.In the event that a continuously formed middle part is desired, the configuration according to claim 3 appears favorable.

Die gemäß Anspruch 4 vorgesehenen Nuten zur Einbringung von Zierleisten ermöglichen es, die Zierleisten problemlos und gleichermaßen haltbar zu befestigen. Diese Zierleisten tragen einerseits zur Verstärkung des markanten ästhetischen Erscheinungsbildes eines erfindungsgemäßen Türblatts bei, andererseits ermöglichen sie es, Toleranzen auszugleichen, welche bei einer industriell durchgeführten Verleimung zweier Teile, deren Oberflächen bereits endbehandelt sind und dementsprechend eine Nachbehandlung nicht mehr möglich machen, notwendigerweise auftreten.The grooves provided according to claim 4 for the introduction of decorative strips make it possible to attach the decorative strips easily and equally durable. On the one hand, these decorative strips contribute to the strengthening of the striking aesthetic appearance of a door leaf according to the invention, on the other hand, they make it possible to compensate for tolerances which necessarily occur when two parts are industrially glued, the surfaces of which have already been finished and, accordingly, post-treatment is no longer possible.

Der Aufbau der Falzteile nach Anspruch 5 stellt sicher, daß gerade in dem inneren mittigen Bereich, in welchem die Beschläge festgelegt sind, sich Spanplattenbereiche hoher Verdichtung, d.h. die Oberflächenbereiche der wenigstens zwei miteinander verleimten Spanplatten befinden. Hierdurch wird ein hohes Maß an Haltbarkeit erzielt.The construction of the folded parts according to claim 5 ensures that in the inner central area in which the fittings are fixed, chipboard areas of high compression, i.e. the surface areas of the at least two chipboards glued together are located. This ensures a high level of durability.

Zur Lösung der erfindungsgemäßen Aufgabe dient auch ein Verfahren nach Anspruch 6. Bei einem derartigen Verfahren werden, wie es die erfindungstypische Konstruktion erlaubt, die Falzteile in großer Stückzahl industriell ohne Berücksichtigung der Einbaumaße des Einzelfalles hergestellt. Bei der Maßanpassung des Türblattes auf eine gewünschte Einbaugröße werden die Falzteile auf die gewünschte und benötigte Länge geschnitten. Das Mittelteil wird im einfachsten Fall an ihrer Unterseite auch entsprechend der gewünschten Länge abgeschnitten, wobei kein Eingriff in den an der Oberseite befindlichen Falz erforderlich ist. In gleicher Weise wird die Breite der Füllung zurechtgeschnitten, wobei dann anschließend die Falzteile mit der Füllung über eine erforderliche Zahl von Dübeln, welche in der Regel geringer ist als die Zahl der in gleichem Abstand zueinander vorsorglich eingebrachten Bohrungen, miteinander verbunden werden. Bei der Herstellung der Türfüllung können individuelle Wünsche, z. B. hinsichtlich einer vorgesehenen Verglasung, durch das Einbringen von Querfriesen problemlos berücksichtigt werden.A method according to claim 6 also serves to achieve the object according to the invention. In such a method, as the construction typical of the invention permits, the folded parts are produced industrially in large numbers without taking into account the installation dimensions of the individual case. When adapting the size of the door leaf to a desired installation size, the rebate parts are cut to the desired and required length. The middle part will in the simplest case also cut off on the underside according to the desired length, with no intervention in the fold located on the upper side being necessary. In the same way, the width of the filling is cut to size, with the folded parts then being connected to the filling using a required number of dowels, which is generally less than the number of holes drilled as a precaution at the same distance from one another. In the manufacture of the door panel, individual requests, e.g. B. with regard to envisaged glazing, can be easily taken into account by introducing cross friezes.

Ausgestaltungsmöglichkeiten des erfindungsgemäßen Verfahrens geben die Unteransprüche 7 und 8 an.The subclaims 7 and 8 provide design options for the method according to the invention.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Dabei zeigt

  • Fig. 1 einen Schnitt durch ein erfindungsgemäßes Türblatt im nichtzusammengesetzten Zustand,
  • Fig. 2 einen vergrößerten Teilschnitt entsprechend Fig. 1 im zusammengesetzten Zustand, und
  • Fig. 3 eine Aufsicht auf ein erfindungsgemäßes Türblatt.
Further features, advantages and details of the invention emerge from the following description of a preferred exemplary embodiment with reference to the drawing. It shows
  • 1 shows a section through a door leaf according to the invention in the non-assembled state,
  • Fig. 2 is an enlarged partial section corresponding to FIG. 1 in the assembled state, and
  • Fig. 3 is a plan view of a door leaf according to the invention.

Ein erfindungsgemäßes Türblatt umfaßt ein Mittelteil 1 und zwei längsverlaufende Falzteile 2 und 3.A door leaf according to the invention comprises a central part 1 and two longitudinal folding parts 2 and 3.

Im Ausführungsbeispiel ist das Mittelteil aufgebaut aus zwei eine seitliche Begrenzung darstellenden Längsriegeln 4, 5, welche mit einem Flächenteil 6 in Hohlzellenwaben-Konstruktion, z. B. aus Natronkraftpappe, verleimt sind. Die Längsriegel 4, 5 und das Flächenteil 6 sind beidseitig durch je eine Hartplatte 7, 8, z. B. 2,8 mm dick, abgedeckt. Auf diese Hartplatten 7, 8 kann ein Furnier mit einer bestimmten Maserung und Färbung oder aber eine Kunststoffbeschichtung bzw. eine Beschichtung aus einem beliebigen Naturmaterial aufgebracht sein. Hierdurch wirkt das Mittelteil 1 nach außen hin einstückig. In die Längsriegel 4, 5 sind Dübelbohrungen 9 eingebracht, welche in Fig. 3 lediglich schematisch dargestellt sind und voneinander einen gleichen Abstand d aufweisen.In the exemplary embodiment, the middle part is constructed from two longitudinal bars 4, 5 which represent a lateral boundary, which are connected to a flat part 6 in a hollow cell honeycomb construction, e.g. B. made of sodium kraft cardboard. The longitudinal bars 4, 5 and the surface part 6 are on both sides by a hard plate 7, 8, z. B. 2.8 mm thick, covered. A veneer with a certain grain and color or a plastic coating or a coating of any natural material can be applied to these hard boards 7, 8. As a result, the central part 1 acts in one piece towards the outside. Dowel bores 9 are made in the longitudinal bars 4, 5, which are only shown schematically in FIG. 3 and are at the same distance d from one another.

Die Falzteile 2, 3 sind jeweils aus zwei miteinander verleimten Spanplatten 10, 11, von z. B. je 19 mm Stärke, aufgebaut. Hierdurch wird erreicht, daß im Bereich der Dübelbohrungen 12 und im Bereich der Befestigungen der in der Zeichnung nicht dargestellten Beschlagteile Oberflächenbereiche der verleimten Platten zu liegen kommen, welche einen hohen Verdichtungsgrad aufweisen und deshalb eine besonders haltbare Befestigung gewährleisten. Die Falze 21 sind in herkömmlicher Weise ausgebildet. An der inneren Schmalseite 13 der Falzteile 2, 3 sind längsverlaufende Ausnehmungen 14, 15 vorgesehen, welche zusammen mit der korrespondierenden Schmalseite 16 der Längsriegel 4, 5 Nuten ausbilden. In diese Nuten werden Zierleisten 17, welche je nach dem gewünschten Stil der Türe ausgebildet sein können, eingesetzt. Die freien Außenseiten 18, 19 der Falzteile 2, 3 können entsprechend der Füllung 1 furniert oder anderweitig beschichtet sein. Zur Erzielung einer besonders ästhetischen Wirkung kann alternativ auch eine Kontrastbeschichtung oder z. B. lediglich ein Furnier mit anders verlaufender Maserung vorgesehen sein. In jedem Fall erhalten die erfindungsgemäßen Türblätter durch die Zusammensetzung aus der flächigen Innenkonstruktion mit den Falzteilen 2, 3 und den im Verbindungsbereich angeordneten Zierleisten 17 ein ästhetisch markantes Aussehen.The folded parts 2, 3 are each made of two glued chipboards 10, 11, z. B. 19 mm thick. It is hereby achieved that in the area of the dowel holes 12 and in the area of the fastenings of the fitting parts, not shown in the drawing, there are surface areas of the glued panels which have a high degree of compaction and therefore ensure a particularly durable attachment. The folds 21 are formed in a conventional manner. On the inner narrow side 13 of the folded parts 2, 3, longitudinal recesses 14, 15 are provided which, together with the corresponding narrow side 16 of the longitudinal bars 4, 5, form grooves. Decorative strips 17, which can be designed depending on the desired style of the door, are inserted into these grooves. The free outer sides 18, 19 of the folded parts 2, 3 can be veneered or otherwise coated in accordance with the filling 1. To achieve a particularly aesthetic effect, a contrast coating or z. B. only a veneer with a different grain can be provided. In any case, the composition of the flat inner construction with the folded parts 2, 3 and the decorative strips 17 arranged in the connection area gives the door leaves according to the invention an aesthetically striking appearance.

Zur Herstellung eines erfindungsgemäßen Türblatts werden vorgefertigte Falzteile 2, 3 und z. B. ein vorgefertigtes Mittelteil 1 mit Längsriegeln 4, 5 je nach Bedarf mit der entsprechenden Oberflächengestaltung versehen ausgewählt. Zur Höhenanpassung wird das Mittelteil 1 an ihrer Unterseite, wo sich also kein Falz befindet, beschnitten und ebenso werden die Falzteile 2, 3 auf die erforderliche Länge gebracht. Zur Erzielung der gewünschten Breite werden dann das Mittelteil 1 bzw. die mit dem Mittelteil 1 verbundenen Längsriegel 4, 5 durch entsprechende Längsschnitte so beschnitten, daß die entstehende Breite zusammen mit der Breite der Falzteile 2, 3 die gewünschte Breite des Türblatts ergibt.To produce a door panel according to the invention, prefabricated folded parts 2, 3 and z. B. selected a prefabricated middle part 1 with longitudinal bars 4, 5 provided with the appropriate surface design as required. To adjust the height, the middle part 1 is trimmed on its underside, ie where there is no fold, and likewise the fold parts 2, 3 are brought to the required length. To achieve the desired width, the central part 1 or the longitudinal bars 4, 5 connected to the central part 1 are trimmed by corresponding longitudinal cuts so that the resulting width together with the width of the folded parts 2, 3 results in the desired width of the door leaf.

Aufgrund der Überdimensionierung der Tiefe t der Dübelbohrungen 9 in den Längsriegeln 4, 5 ist gewährleistet, daß auch bei einer Reduktion der Breite des Mittelteils 1 eine ausreichende Tiefe der Dübelbohrung zur Verfügung steht. Anschließend werden die Falzteile 2, 3 mit dem Mittelteil 1 durch Dübel 20 verbunden, worauf dann in die durch die Ausnehmungen 14, 15 gebildeten Nuten Zierleisten 17 eingesetzt und befestigt werden.Due to the oversizing of the depth t of the dowel bores 9 in the longitudinal bars 4, 5 it is ensured that a sufficient depth of the dowel bore is available even when the width of the central part 1 is reduced. Subsequently, the folded parts 2, 3 are connected to the middle part 1 by means of dowels 20, whereupon decorative strips 17 are then inserted and fastened into the grooves formed by the recesses 14, 15.
