Abstract

The door has a middle layer (2) and inserted edge bands which are covered on both sides by a layer (6) of covering plates each 4.5 to 6.5 millimetres thick and 80 to 140 millimetres wide. The middle layer has an inner layer (3) of block-bonded bars (4') or panels whose fibres point crosswise to the bars (3') of the inner layer. The inset edge bands with the covering plate layers are not bonded with the middle layer. The bars of the inner layer are between 15 and 25 millimetres thick and between 25 and 40 millimetres wide. The bars of the outer layers (4) are between 4.5 and 6.5 millimetres thick and between 85 and 110 millimetres wide.

Description

Die Erfindung bezieht sich auf einen Türrohling oder Tür aus Massivholz, bestehend aus einer Mittellage, die eine Anzahl vertikaler, aneinanderstoßender Stäbe enthält, und aus an zumindest einer Seite an diese anschließenden Einleimern, wobei die Mittellage samt den Einleimern beidseitig von einer Decklamellenlage überdeckt ist.The invention relates to a door blank or door made of solid wood, consisting of a middle layer, which contains a number of vertical, abutting bars, and of at least one side of the glue-in strips, the central layer, including the glue-in strips, being covered on both sides by a cover lamella layer.

Der Trend zur Verwendung natürlicher und leicht entsorgbarer Baumaterialien hat auch bei der Herstellung von Türen dazu geführt, daß nach Möglichkeit auf Spanplatten verzichtet wird, da diese insbesondere Formaldehyd abgeben. Man geht daher immer mehr zu Massivholztüren über. Innentüren, die als Rahmentüren gefertigt sind, werden seit langem ausschließlich aus verleimten Holzteilen hergestellt. Es besteht jedoch auch ein Bedarf nach glatten und massiven Holztüren, die robust sind und sich auch bei wechselnder Temperatur und Luftfeuchtigkeit nicht verziehen.The trend towards the use of natural and easily disposable building materials has also led to the fact that chipboard has been avoided as far as possible since it releases formaldehyde in particular. One is therefore moving more and more to solid wood doors. Interior doors that are made as frame doors have long been made exclusively from glued wooden parts. However, there is also a need for smooth and solid wooden doors that are robust and do not warp even when the temperature and humidity change.

Aus der US 3,165,792 A ist eine Tür der eingangs genannten Art bekannt geworden, die einen umlaufenden Rahmen aufweist, in den eine Kernschicht oder Mittellage aus vertikal verlaufenden, aneinanderstoßenden Stäben eingelegt ist. Diese Mittellage ist beidseitig von einer zweischichtigen Decklage überdeckt, die aus einer auf die Stäbe aufgeleimten Unterfurnierlage und einer auf diese aufgeleimten Außenfurnierlage besteht. Um ein Verwerfen der Tür zu verhindern, sind nicht alle Stäbe der Mittelschicht durchgehend ausgebildet, vielmehr sind einige Außenstäbe und ein Mittelstab in je zwei kurze und einen längeren Stab unterteilt. Dies zeigt, daß die Konstruktion prinzipiell anfällig gegen ein Verwerfen bzw. Verziehen ist. Der umlaufende Rahmen muß weiters einen eingefrästen und gleichfalls umlaufenden Absatz zur bündigen Aufnahme einer genau passenden, inneren Furnierlage aufweisen, wodurch die Herstellung erschwert wird, insbesondere falls Türrohlinge produziert werden sollen.From US 3,165,792 A a door of the type mentioned has become known, which has a circumferential frame, in which a core layer or middle layer of vertically running, abutting rods is inserted. This middle layer is covered on both sides by a two-layer cover layer, which consists of a bottom veneer layer glued onto the rods and an outer veneer layer glued onto them. In order to prevent the door from being warped, not all bars of the middle layer are designed to be continuous, rather some outside bars and a middle bar are divided into two short bars and one longer bar. This shows that the construction is in principle susceptible to warping or warping. The circumferential frame must also have a milled and also circumferential heel for flush reception of a precisely fitting inner veneer layer, which makes production more difficult, especially if door blanks are to be produced.

Es ist eine Aufgabe der Erfindung, einen Türrohling oder eine Tür zu schaffen, die sich - bei vernünftigem Herstellungsaufwand - bei Änderungen von Temperatur und/oder Feuchtigkeit nicht verzieht.It is an object of the invention to provide a door blank or a door that does not warp with changes in temperature and / or humidity - with a reasonable manufacturing outlay.

Diese Aufgabe wird mit einer Tür der eingangs genannten Art gelöst, bei welcher erfindungsgemäß die Mittellage eine innere Schicht aus blockverleimten Stäben aufweist, sowie zwei äußere Schichten, welche aus blockverleimten Stäben oder Platten bestehen, die mit ihrer Faserrichtung quer zu den Stäben der inneren Schicht bzw. deren Faserrichtung verlaufen.This object is achieved with a door of the type mentioned at the outset, in which, according to the invention, the middle layer has an inner layer of block-glued bars, and two outer layers Layers, which consist of block-glued rods or plates, which run with their fiber direction transverse to the rods of the inner layer or their fiber direction.

Die Tür nach der Erfindung weist eine besonders hohe Verzugsfreiheit und Dimensionsstabilität auf und Rißbildungen sind so gut wie ausgeschlossen.The door according to the invention has a particularly high freedom from warping and dimensional stability and cracking is practically impossible.

Es hat sich auch als günstig erwiesen, wenn die Einleimer mit den Decklamellenlagen, nicht jedoch mit der Mittellage verleimt sind.It has also proven to be advantageous if the edge banding is glued to the top lamella layers, but not to the middle layer.

Praxisbewährte Ausführungen zeichnen sich dadurch aus, daß die Decklamellen je 4,5 bis 6,5 mm dick und 80 bis 140 mm breit sind und/oder die Stäbe der inneren Schicht zwischen 15 und 25 mm dick und zwischen 25 und 40 mm breit sind und/oder die Stäbe der äußeren Schichten zwischen 4,5 und 6,5 mm dick und zwischen 85 und 110 mm breit sind.Practical designs are characterized in that the cover slats are 4.5 to 6.5 mm thick and 80 to 140 mm wide and / or the bars of the inner layer are between 15 and 25 mm thick and between 25 and 40 mm wide and / or the bars of the outer layers are between 4.5 and 6.5 mm thick and between 85 and 110 mm wide.

Die gewünschten Eigenschaften einer Türe nach der Erfindung ergeben sich insbesondere, falls sie unter Verwendung eines Leims der Verleimungsklasse AW 100 heißverpreßt ist.The desired properties of a door according to the invention result in particular if it is hot-pressed using a glue of the gluing class AW 100.

Die Erfindung samt weiterer Vorteile ist im folgenden an Hand eines Ausführungsbeispiels näher erläutert, das in der Zeichnung veranschaulicht ist. In dieser zeigen Fig. 1 eine schematische Vorderansicht einer Tür nach der Erfindung, Fig. 2 einen Schnitt längs der Linie II-II der Fig. 1, teilweise dargestellt in vergrößerter Darstellung und Fig. 3 einen Schnitt längs der Linie III-III der Fig. 1, gleichfalls nur teilweise dargestellt und vergrößert.The invention together with further advantages is explained in more detail below using an exemplary embodiment which is illustrated in the drawing. 1 shows a schematic front view of a door according to the invention, FIG. 2 shows a section along the line II-II of FIG. 1, partially shown in an enlarged view, and FIG. 3 shows a section along the line III-III of FIG 1, also only partially shown and enlarged.

Wie aus den Figuren 1 bis 3 hervorgeht, weist eine Tür 1 bzw. Türrohling nach der Erfindung eine Mittellage 2 auf, die dreischichtig aufgebaut ist. Eine innere Schicht 3 besteht aus blockverleimten Stäben 3', die mit ihrer Faserrichtung in Längsrichtung der Tür verlaufen - bei eingebauter Tür somit vertikal. Die Stäbe 3' weisen bei einer bevorzugten Ausführungsform einen rechteckigen Querschnitt von 15 bis 25 mm x 25 bis 40 mm auf.As can be seen from FIGS. 1 to 3, a door 1 or blank according to the invention has a middle layer 2 which is constructed in three layers. An inner layer 3 consists of block-glued bars 3 ', which run with their fiber direction in the longitudinal direction of the door - thus vertically when the door is installed. In a preferred embodiment, the bars 3 ′ have a rectangular cross section of 15 to 25 mm × 25 to 40 mm.

Auf die innere Schicht 3 sind beidseitig äußere Schichten 4 aufgeleimt, die gleichfalls je aus blockverleimten Stäben 4' besteht. Die Stäbe 4' verlaufen mit ihrer Faserrichtung normal zu den Stäben 3', bei eingebauter Tür 1 somit horizontal und sie besitzen bei einer bevorzugten Ausführung einen Querschnitt von 4,5 bis 6,5 mm x 85 bis 110 mm.On the inner layer 3, outer layers 4 are glued on both sides, which likewise each consist of block-glued rods 4 '. The bars 4 'run with their fiber direction normal to the bars 3', thus horizontally when the door 1 is installed and, in a preferred embodiment, they have a cross section of 4.5 to 6.5 mm × 85 to 110 mm.

Die Stäbe 3' und 4' können, besonders wenn sie geringe Dicke und Länge aufweisen, ebenso als Platten bezeichnet werden.The bars 3 'and 4', especially if they have a small thickness and length, can also be referred to as plates.

Die Mittellage 2 ist an allen vier Seiten von Einleimern 5 umgeben, die als Massivholzstäbe, z.B. mit einem Querschnitt von 45 x 30 bis 55 x 40 mm, ausgebildet sind. Die vier Einleimer 5 bilden somit einen Rechteckrahmen für die Mittellage 2, sie sind bevorzugterweise jedoch nicht mit der Mittellage verleimt.The middle layer 2 is surrounded on all four sides by glue-in strips 5, which as solid wood rods, e.g. with a cross section of 45 x 30 to 55 x 40 mm. The four glues 5 thus form a rectangular frame for the middle layer 2, but they are preferably not glued to the middle layer.

Auf diesen Aufbau ist beiderseits je eine Lage 6 aus Decklamellen 6' aufgeleimt. Die Decklamellen 6' sind z.B. 4,5 bis 6,5 mm dick und 80 bis 140 mm breit und auch an ihren Kanten miteinander verleimt, sodaß sie je eine Scheibe der gesamten Sandwichkonstruktion der Tür 1 bilden.A layer 6 of cover slats 6 'is glued onto this structure on both sides. The cover slats 6 'are e.g. 4.5 to 6.5 mm thick and 80 to 140 mm wide and also glued together at their edges, so that they each form a pane of the entire sandwich construction of door 1.

Sämtliche genannten Verleimungen erfolgen mit Vorteil mit einem Leim der Verleimungsklasse AW 100 nach DIN 68705, B1.3 unter Heißverpressen.All of the above-mentioned gluing operations are advantageously carried out with glue of the gluing class AW 100 according to DIN 68705, B1.3 under hot pressing.

Die Tür 1 nach der Erfindung besitzt einen sehr guten Absperreffekt. Es ergibt sich eine hohe Verzugsfreiheit und Dimensionsstabilität und die Rißbildungsgefahr ist vernachlässigbar klein.The door 1 according to the invention has a very good shut-off effect. There is a high degree of freedom from distortion and dimensional stability and the risk of cracking is negligible.

Der Türrohling wird in den gewünschten, meist Normen entsprechenden Abmessungen hergestellt und später erforderlichenfalls auf die genaue Größe zugeschnitten Ebenso wurden Ausnehmungen für Beschläge, Falze, Anschläge, etc. gefräst.The door blank is produced in the desired dimensions, usually in accordance with standards, and later cut to the exact size if necessary. Recesses for fittings, rebates, stops, etc. were also milled.

Da die Tür 1 bzw. der Türrohling vollständig aus Massivholz besteht, ist die Tür gesundheitsmäßig unbedenklich und kann im Bedarfsfall auch umweltfreundlich entsorgt werden. Dennoch weist sie mechanische Eigenschaften auf, die bisher mit Massivholztüren schwer zu erreichen waren.Since the door 1 or the door blank consists entirely of solid wood, the door is harmless to health and can also be disposed of in an environmentally friendly manner if necessary. Nevertheless, it has mechanical properties that were previously difficult to achieve with solid wood doors.
