Description
Die Erfindung bezieht sich auf Zimmer- oder andere Türen, welche aus mit härtbaren Bindemitteln versehenen Faserstoffen, insbesondere Holzfurnieren., hergestellt werden.The invention relates to room or other doors, which from Fibers provided with hardenable binders, in particular wood veneers., getting produced.
Es ist bekannt, Türen massiv aus Holz oder hohl aus zusammengesetzten Sperrholz- oder Kunststoffplatten herzustellen. Letztere Bauart hat den Nachteil, daß sie durch das Zusammenfügen der Platten mittels Schrauben oder Leimung und durch das nachträgliche Einarbeiten der Ausnehmungen für Scharniere und Schloß zeitraubend und teuer ist. Die massiven Türen ,besitzen noch den Übelstand, daß sie verhältnismäßig schwer und nicht genügend schalldämpfend und wärmeisolierend sind.It is known to have doors made of solid wood or hollow made of composite Manufacture plywood or plastic panels. The latter type has the disadvantage that they are made by joining the panels by means of screws or gluing and through the subsequent incorporation of the recesses for the hinges and lock is time-consuming and is expensive. The massive doors still have the disadvantage that they are proportionately are heavy and not sufficiently sound-absorbing and heat-insulating.
Die Nachteile der bekannten Türen werden gemäß der Erfindung dadurch vermieden, daß die Tür aus überelnandergeschichteten, bei Anwendung von Druck und Hitze in an sich bekannter Weise mittels Kunstharz in einem Arbeitsgang miteinander verbundenen Faserstoffschichten, vorzugsweise - Holzfurnieren, besteht, wobei innerhalb des Querschnittes durch heiz- und kühlbare Einlegedorne erzeugte Hohlräume und an den Seitenkanten Ausnehmungen zur Aufnahme der Scharniere und des Schlosses vorgesehen sind. Hierbei wird zweckmäßig der Harzgehalt so niedrig, vorzugsweise unter 2o °/o, bemessen, daß bei noch genügender Bindung der Furniere eine hohe Schlagbiegefestigkeit erreicht wird.The disadvantages of the known doors are thereby according to the invention avoided the door from being stacked on top of each other when applying pressure and Heat together in a known manner by means of synthetic resin in one operation connected fiber layers, preferably - wood veneers, consists, within of the cross-section created by heatable and coolable insertion mandrels and cavities the side edges are provided with recesses to accommodate the hinges and the lock are. In this case, the resin content is expediently so low, preferably below 2o%, dimensioned so that with sufficient bonding of the veneers a high impact resistance is achieved.
Zur Erzielung von kurzen Fertigpreßzeiten bestehen vorteilhaft die zur Verstärkung dienenden Rippen aus vor- oder fertiggepreßtenLeisten, welche beim Fertigpressen zweckmäßig mit einer dünnen Schicht nicht ausgehärteten Kunststoffes, vorzugsweise mit Kunststoff imprägniertem Bahnwerkstoff aus Papier, Gewebe oder Holzfurnieren, versehen und so zu einem einheitlichen Körper zusammengepreßt werden. Um eine hohe Festigkeit zu erreichen, werden die einzelnen Faserstoffbahnen vorteilhaft um go'°' versetzt verlegt.To achieve short finishing press times, there are advantageous ribs made of pre-pressed or ready-pressed strips, which are used for reinforcement Ready-to-use pressing with a thin layer of uncured plastic, preferably with plastic impregnated sheet material made of paper, fabric or Wood veneers, provided and thus pressed together to form a single body. In order to achieve a high level of strength, the individual fiber webs are advantageous Relocated by go '°'.
Zur Erzielung einer edelholzähnlichen Oberfläche können die äußeren Kunststofflagen der Tür vor dem Pressen mit einem Edelholz- oder gemaserten Kunsth.arzdeckbogen versehen werden. In diesem Fall erübrigt sich ein nachträgliches Lackieren der Tür.To achieve a surface similar to fine wood, the outer Plastic layers of the door before pressing with a fine wood or grained synthetic resin cover sheet be provided. In this case, there is no need to paint the door afterwards.
Damit die Tür bei großem Widerstandsmoment möglichst leicht wird, wird sie erfindungsgemäß bei Verwendung von vorzugsweise mit niedrigem Harzgehalt versehenen Holzfurnieren unter Anwendung von Hitze und mit geringem spezifischem Preßdruck in den Grenzen von 2o bis 6o kg/cm2 fertiggepreßt. Eis wird :dadurch ein spezifisches Gewicht von nur etwa 0,7 g/cm3 gegenüber sonstigen Preßstoffteilen von etwa i,4 g/gms erreicht.So that the door is as light as possible with a high section modulus, it is finished-pressed according to the invention using wood veneers preferably provided with a low resin content using heat and low specific pressure within the limits of 20 to 60 kg / cm2. Ice is: thereby achieved a specific weight of only about 0.7 g / cm3 compared to other molded parts of about 1.4 g / gms.
In der Zeichnung ist ein Ausführungsbeispiel einer Tür gemäß der Erfindung dargestellt, und zwar zeigt Abb. i eine Vorderansicht der Tür, Abb. 2 einen Schnitt nach der Linie A-A, Abb. 3 einen Schnitt nach der Linie B-B der Abb. i.In the drawing is an embodiment of a door according to the invention shown, namely Fig. i shows a front view of the door, Fig. 2 shows a section along the line A-A, Fig. 3, a section along the line B-B of Fig. i.
Hierbei bedeuten a die Außenflächen der Tür, b die von diesen Außenflächen zum Zweck der Gewichtsersparnis sowie zur Schall- und Wärmeisolation eingeschlossenen Hohlräume; c die Ausnehmungen für die Aufnahme der Scharniere, d einen Hohlraum zur Aufnahme des Schlosses mit Klinke, e, f, g, lt den Rahmen mit den Verstärkungsrippen, welche aus vor- oder fertiggepreßten Leisten bestehen, die beim Fertigpressen mit den Außenflächen zu einem einheitlichen Körper vereinigt werden.Here, a denotes the outer surfaces of the door, b the cavities enclosed by these outer surfaces for the purpose of saving weight and for sound and heat insulation; c the recesses for receiving the hinges, d a cavity to accommodate the lock with a latch, e, f, g, lt the frame with the reinforcing ribs, which consist of pre-pressed or finished-pressed strips, which when finished pressing with the outer surfaces to form a uniform Bodies are united.
