Abstract

The window frame is made up of frame legs (1, 2) which each have a rebated part (1.1, 2.1) on their inner sides. The frame legs (1, 2) are connected to one another in each corner of the frame via a wedge-type finger-jointed portion (3, 4) in each case. The section (3), of said finger-jointed portion, located in the region of the rebated parts (1.1, 2.1) runs approximately in a mitred manner. Each wedge-type finger-jointed portion (3, 4) contains, adjoining the mitred section (3), in each case a section (4) which runs tangentially thereto in an arcuate manner. The arcuate section (4) extends over an angle ( alpha ) of approximately 45 DEG . The outer end, located in the outside surface (A) of one frame leg (2), of the wedge-type finger-jointed portion (3, 4) is essentially perpendicular to said outside surface (A). This avoids any displacements in the wedge-type finger-jointed portion (3, 4) which could arise when the frame legs (1, 2) are pressed together. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Fensterrahmen mit Rahmenschenkeln, aus Holz, die an ihren inneren Seiten je eine abgefälzte Partie aufweisen und die in jeder Ecke des Rahmens miteinander verbunden sind.The invention relates to a window frame with frame legs, made of wood, attached to their inner Pages each have a rebated section and the in every corner of the frame are connected together.

Der Fensterrahmen kann sowohl ein Blendrahmen als auch ein Flügelrahmen sein.The window frame can be a frame as well also be a sash.

Die Aufgabe der Erfindung besteht darin, die Verbindungen der Bestandteile des Fensterrahmens miteinander so zu gestalten, dass sich die Bestandteile beim Verpressen selbständig in die gewünschte Endposition bringen und dass sich biegesteife und formstabile Verbindungen ergeben.The object of the invention is that Connections of the components of the window frame with each other to be designed so that the components of the Press independently into the desired end position bring and that there are rigid and dimensionally stable connections surrender.

Ein Fensterrahmen der angegebenen Art, bei welchem die Rahmenschenkel in den Ecken des Rahmens über je eine Keilverzinkung miteinander verbunden sind, deren im Bereich der abgefälzten Partien liegender Abschnitt mindestens annähernd in Gehrung verläuft, wobei jede Keilverzinkung im Anschluss an den etwa in Gehrung verlaufenden Abschnitt jeweils einen tangential zu diesem bogenförmig verlaufenden Abschnitt aufweist, ist z.B. aus der CH-PS 546 877 bekannt. Nach dieser soll der bogenförmige Abschnitt jeder Keilverzinkung symmetrisch bezüglich der zur Rahmenebene senkrechten Längsmittelebene der Vollholzpartie eines der Rahmenschenkel verlaufen. Das bedeutet, dass nicht nur das innere Ende des bogenförmigen Abschnittes, das tangential an den in Gehrung verlaufenden Abschnitt anschliesst, sondern auch das äussere Ende des bogenförmigen Abschnittes, das auf der Aussenseite des betreffenden Rahmenschenkels liegt, um jeweils etwa 45° zur Längsrichtung des Rahmenschenkels geneigt sind. Der bogenförmige Abschnitt jeder Keilverzinkung hat ein Krümmungszentrum, das in der genannten Längsmittelebene der Vollholzpartie des einen Rahmenschenkels liegt. Beim Zusammenpressen der Rahmenschenkel ergibt sich eine Zentrierung auf das Krümmungszentrum. Dabei können an der Aussenseite des Rahmenschenkels, wo der bogenförmige Abschnitt der Keilverzinkung endet, unschöne und störende Verschiebungen der Keilverzinkung auftreten.A window frame of the specified type, in which the frame legs in the corners of the frame over each a finger jointing are connected to each other, whose in At least the area of the rebated sections runs approximately in miter, with each finger joint following the roughly mitred Section each tangent to this arcuate extending portion is e.g. from the CH-PS 546 877 known. According to this, the arcuate section each finger joint symmetrical with respect to Frame plane vertical longitudinal center plane of the solid wood section one of the frame legs run. That means, that not only the inner end of the arcuate section, the tangential to the mitred section connects, but also the outer end of the arcuate section which is on the outside of the relevant frame leg is, in each case by about 45 ° are inclined to the longitudinal direction of the frame leg. Of the arcuate section of each finger joint has a center of curvature, that in the said median longitudinal plane Solid wood section of one frame leg lies. At the Pressing the frame legs together results in centering to the center of curvature. You can at the Outside of the frame leg, where the arcuate section the finger jointing ends, unsightly and annoying Shifts in finger jointing occur.

Um solche Verschiebungen zu vermeiden, ist der erfindungsgemässe Fensterrahmen dadurch gekennzeichnet, dass sich der bogenförmige Abschnitt jeder Keilverzinkung jeweils über einen Winkel von etwa 45° erstreckt, so dass die Tangente an das äussere Ende des bogenförmigen Abschnittes zu einem der Rahmenschenkel etwa senkrecht steht.To avoid such shifts, the Window frames according to the invention characterized in that that the arcuate section of each finger joint each extends over an angle of approximately 45 °, so that the tangent to the outer end of the arcuate section approximately perpendicular to one of the frame legs stands.

Vorzugsweise enthält die Keilverzinkung zwischen dem äusseren Ende des bogenförmigen Abschnittes und der Aussenseite des Rahmenschenkels noch einen geradlinigen, zur Längsrichtung des Rahmenschenkels etwa senkrechten Abschnitt.Preferably, the finger jointing contains between the outer end of the arcuate portion and the Outside of the frame leg another straight, section approximately perpendicular to the longitudinal direction of the frame leg.

Da das äussere Ende der Keilverzinkung, das in der Aussenseite des einen Rahmenschenkels liegt, zu dieser Aussenseite etwa senkrecht steht, können Kräfte, die beim Zusammenpressen der Rahmenschenkel ausgeübt werden, nicht zu Verschiebungen der Keilverzinkung an der Aussenseite des einen Rahmenschenkels führen.Since the outer end of the finger jointing, which in the outside of one frame leg lies to this Outside is approximately vertical, forces that when Squeezing the frame legs are not exercised to displacements of the finger joint on the outside of one frame leg.

Ein Fensterrahmen kann zusätzlich zu den vier Rahmenschenkeln auch noch wenigstens ein Unterteilungselement in Form eines Setzholzes oder eines Kämpfers (beim Blendrahmen) oder in Form einer Sprosse (beim Flügelrahmen) enthalten, welches Unterteilungselement sich von einem der Rahmenschenkel zum gegenüberliegenden Rahmenschenkel oder zu einem anderen Unterteilungselement erstreckt. Bei einem solchen Fensterrahmen wird die der Erfindung gestellte Aufgabe dadurch gelöst, dass das Unterteilungselement an seinen beiden Enden über je eine Keilverzinkung angeschlossen ist, die im Bereich der abgefälzten Partien bogenförmig verlaufende Abschnitte aufweist. In bekannten Fensterrahmen waren solche Unterteilungselemente üblicherweise mit Schlitz und Zapfen, mit Dübeln oder mit Schrauben angeschlossen. Dabei waren Probleme durch Schwinden und Quellen des Holzes nicht zu vermeiden. A window frame can be in addition to the four Frame legs also at least one subdivision element in the form of a set wood or a fighter (at Frame) or in the form of a rung (in the casement) contain which subdivision element differs from one of the frame legs to the opposite frame leg or extends to another subdivision element. With such a window frame the Invention problem solved in that the Subdivision element at each of its two ends Is connected in the area of rebated sections arcuate sections having. Such dividing elements were in known window frames usually with slot and pin, with Dowels or connected with screws. Were there Problems caused by shrinkage and swelling of the wood do not increase avoid.

Beschädigungen der Verbindungen in Holzfensterrahmen durch Schwinden und Quellen des Holzes sind stets zu befürchten. Um die Gefahr von solchen Beschädigungen auf ein Minimum zu reduzieren, ist ein erfindungsgemässes Verfahren zur Herstellung eines Fensterrahmens aus balkenförmigen Holzelementen (Rahmenschenkeln und ggf. Unterteilungselementen) dadurch gekennzeichnet, dass in die Enden der balkenförmigen Holzelemente ineinanderpassende Keilverzinkungen eingearbeitet werden, dass die Keilverzinkungen dann imprägniert werden und dass die mit den Keilverzinkungen versehenen und imprägnierten Enden jedes Holzelementes nachher mit jeweils einem anderen der Holzelemente verleimt werden.Damage to the connections in wooden window frames by shrinking and swelling of the wood are always to fear. To the risk of such damage To reduce to a minimum is one according to the invention Process for producing a window frame from beam-shaped Wooden elements (frame legs and, if necessary, subdivision elements) characterized in that in the Ends of the beam-shaped wooden elements mating Finger joints are incorporated that the finger joints then be impregnated and that with the Finger-jointed and impregnated ends each Wood element afterwards with a different one of the wood elements be glued.

Die miteinander zu verbindenden Stirnflächen der Rahmenschenkel sind jeweils mit einer Keilverzinkung versehen. Die Keilverzinkung enthält im Bereich der abgefälzten Partien 1.1 und 2.1 einen in Gehrung verlaufenden Abschnitt 3. An diesen Abschnitt 3 schliesst sich ein bogenförmiger Abschnitt 4 an, der tangential zum Abschnitt 3 verläuft. Der bogenförmige Abschnitt erstreckt sich über einen Winkel α von etwa 45°, so dass die Tangente t an das äussere Ende E des bogenförmigen Abschnittes 4 der Keilverzinkung zur Längsrichtung und damit zur Aussenseite A des Rahmenschenkels 2 etwa senkrecht steht.

An das äussere Ende E des bogenförmigen Abschnittes 4 anschliessend enthält die Keilverzinkung einen geradlinig verlaufenden Abschnitt 5, der in der Aussenseite A des Rahmenschenkels 2 endet und zu dieser Aussenseite A etwa senkrecht steht.1 and 2 schematically show the end portions of two mutually perpendicular frame legs 1 and 2 of a wooden window frame, the one Form the corner of the frame. The window frame can be a Sash frame as well as a frame. Every frame leg points to its inner with respect to the frame Each page has a rebated section 1.1 or 2.1. The end faces of the frame legs to be connected to one another are each finger-jointed. The Finger jointing contains in the area of the rebated sections 1.1 and 2.1 a mitred section 3. An this section 3 is closed by an arcuate section 4, which runs tangentially to section 3. Of the arcuate section extends over an angle α of about 45 °, so that the tangent t to the outer end E of the arcuate portion 4 of the finger jointing Longitudinal direction and thus to the outside A of the frame leg 2 is approximately vertical. The arcuate section 4 expediently follows an arc with a Center of curvature K. To the outer end E of the arcuate Section 4 then contains the finger jointing a rectilinear section 5, which in the Outside A of the frame leg 2 ends and to this Outside A is approximately vertical.

    Vor dem Zusammenfügen der beiden Rahmenschenkel, also in dem Zustand, wie er in Fig. 1 dargestellt ist, werden die beiden miteinander zu verbindenden Keilverzinkungen imprägniert. Die Imprägnierung erfolgt sehr wirksam, weil die miteinander zu verbindenden Flächen zu einem grossen Teil im Hirnholz liegen und damit saugfähig sind. Zudem sind die Flächen durch die eingearbeiteten Keilverzinkungen vergrössert. Nach dem Imprägnieren werden die Flächen miteinander verleimt. Durch das Imprägnieren der Keilverzinkungen vor dem Verleimen ist im fertigen Fensterrahmen die Gefahr des Eindringens von Feuchtigkeit in das Holz, und damit eines Quellens und Schwindens des Holzes, stark verringert. Die Verbindung der beiden Rahmenschenkel bleibt daher während einer langen Lebensdauer stabil.Before joining the two frame legs, in the state as shown in Fig. 1, become the two finger joints to be joined together impregnated. The impregnation takes place very much effective because the areas to be joined together a large part in the end grain and therefore absorbent are. In addition, the areas are incorporated by the Finger jointing enlarged. After impregnation the surfaces glued together. By impregnation the finger jointing before gluing is finished Window frames the risk of moisture penetration into the wood, and with it a swelling and shrinking of the Wood, greatly reduced. The connection of the two frame legs therefore remains for a long life stable.

    Die Fig. 3 zeigt in gleicher Darstellung wie Fig. 2 die Enden von zwei Rahmenschenkeln 11 und 12, die eine Ecke eines Fensterrahmens bilden. Die Rahmenschenkel 11 und 12 weisen an ihren inneren Seiten je eine abgefälzte Partie 11.1 bzw. 12.1 auf. Die Stirnflächen der Rahmenschenkel 11 und 12 sind miteinander über eine Keilverzinkung verbunden, die wieder im Bereich der abgefälzten Partien den im wesentlichen in Gehrung verlaufenden Abschnitt 3 enthält, an den sich tangential der bogenförmige Abschnitt 4 anschliesst. Der bogenförmige Abschnitt 4 erstreckt sich über den Winkel α von etwa 45°, die Tangente t an das äussere Ende E steht zum Rahmenschenkel 12 etwa senkrecht.3 shows in the same representation as Fig. 2 the ends of two frame legs 11 and 12, one Form the corner of a window frame. The frame legs 11 and 12 each have a rebate on their inner sides Lot 11.1 or 12.1. The end faces of the frame legs 11 and 12 are splined together connected, again in the area of the rebated Games the essentially mitred section 3 contains, tangent to the arcuate Section 4 follows. The arcuate section 4 extends over the angle α of about 45 °, the tangent t at the outer end E is to the frame leg 12 about vertical.

    Da der Rahmenschenkel 12 eine grössere Breite hat als der Rahmenschenkel 2 in Fig. 1 und 2, enthält die Keilverzinkung im Anschluss an das äussere Ende E des bogenförmigen Abschnittes 4 einen geradlinigen, zum Rahmenschenkel 12 etwa senkrechten Abschnitt 15, der länger ist als der geradlinige Abschnitt 5 in Fig. 2.Since the frame leg 12 has a larger width as the frame leg 2 in Figs. 1 and 2, contains the Finger jointing following the outer end E of the arcuate section 4 a straight line to the frame leg 12 approximately vertical section 15, the longer is as the rectilinear section 5 in FIG. 2.

    In beiden beschriebenen Ausführungsbeispielen der Erfindung steht das äussere Ende der Keilverzinkung, das in der Aussenfläche A des einen Rahmenschenkels 2 bzw. 12 liegt, zu dieser Aussenseitenfläche A etwa senkrecht. Daher führen Kräfte, die beim Zusammenpressen der Rahmenschenkel 1 und 2 bzw. 11 und 12 angelegt werden, nicht zu Verschiebungen in der Keilverzinkung in der Aussenseitenfläche A.In both described embodiments of the Invention stands the outer end of the finger jointing that in the outer surface A of one frame leg 2 or 12 is approximately perpendicular to this outer side surface A. Therefore, lead forces when compressing the frame legs 1 and 2 or 11 and 12 are not created Shifts in the finger joint in the outside surface A.

Die Keilverzinkungen enthalten im Bereich der abgefälzten Partien 30.1, 30.2, 31.1 zwei bogenförmige Abschnitte 32 und 33, die sich bis auf eine Tiefe t in den Vollholzteil des Rahmenschenkels 31 hinein erstrecken. Die Tiefe t ist wenigstens gleich gross wie die Zinkentiefe der Keilverzinkungen. Die beiden bogenförmigen Abschnitte 32 und 33 der Keilverzinkung sind miteinander durch einen geradlinig im Vollholzteil des Rahmenschenkels 31 verlaufenden Abschnitt 34 verbunden, der tangential an die bogenförmig verlaufenden Abschnitte 32 und 33 anschliesst. Der geradlinige Abschnitt 34 ist zur Längsrichtung des Rahmenschenkels 31 parallel und hat eine Länge, die je nach der Breite des Unterteilungselementes 30 unterschiedlich sein kann.8 and 9 schematically show an end portion a dividing element 30, which as above explains a setwood, a fighter or one May be rung, and a section of a frame leg 31. Element 31 could also be a second one Subdivision element. The frame leg 31 has a rebated facing the dividing element 30 Lot 31.1, and has the dividing element 30 sections 30.1 and 30.2 rebated on both sides. In the End face of the partitioning element 30 and in the the cut-off 31.1 side of the frame leg 31 finger joints are milled. The finger joints included in the area of the rebated sections 30.1, 30.2, 31.1 two arcuate sections 32 and 33 that extend up to to a depth t in the solid wood part of the frame leg 31 extend into it. The depth t is at least the same as large as the tine depth of the finger joints. The two arcuate sections 32 and 33 of the finger jointing with each other by a straight line in the solid wood part of the Frame leg 31 extending portion 34 connected the tangent to the arcuate sections 32 and 33 connects. The straight section 34 is parallel to the longitudinal direction of the frame leg 31 and has a length that depends on the width of the partitioning element 30 can be different.

    Vor dem Zusammenfügen des Unterteilungselementes 30 mit dem Rahmenschenkel 31, also in dem Zustand, wie er in Fig. 8 dargestellt ist, werden an beiden Teilen die Keilverzinkungen imprägniert. Nach dem Imprägnieren werden die Keilverzinkungen miteinander verleimt. Beim Anpressen des Unterteilungselementes 30 an den Rahmenschenkel 31 bringt sich das Unterteilungselement 30 dank der beschriebenen Form der Keilverzinkungen selbständig in die gewünschte Endposition bezüglich des Rahmenschenkels 31. Durch das Imprägnieren der Keilverzinkungen vor dem Verleimen ist im fertigen Fensterrahmen die Gefahr des Eindringens von Feuchtigkeit in das Holz, und damit die Gefahr des Quellens und Schwindens des Holzes, stark verringert. Die Verbindung bleibt daher während einer langen Lebensdauer stabil.Before joining the subdivision element 30 with the frame leg 31, so in the state as he is shown in Fig. 8, on both parts Impregnated finger joints. After impregnation the finger joints glued together. When pressing of the dividing element 30 on the frame leg 31 brings the dividing element 30 thanks to the described The shape of the finger jointing can be changed into the desired one End position with respect to the frame leg 31. By impregnating the finger joints before gluing there is a risk of intrusion in the finished window frame of moisture in the wood, and thus the Danger of swelling and shrinking of the wood, strong decreased. The connection therefore remains during one long life stable.

    Die Fig. 10 zeigt in gleicher Darstellung wie Fig. 9 einen Endabschnitt eines Unterteilungselementes 40 und einen Abschnitt eines Rahmenschenkels (oder anderen Unterteilungselementes) 41. Der Rahmenschenkel 41 besitzt eine abgefälzte Partie 41.1, und das Unterteilungselement 40 hat an beiden Seiten abgefälzte Partien 40.1 bzw. 40.2. Die in Fig. 10 gezeigten Teile unterscheiden sich von den in Fig. 9 gezeigten nur dadurch, dass in Fig. 10 die abgefälzten Partien 40.1 und 40.2 des Unterteilungselementes 40 breiter sind als die abgefälzten Partien 30.1 und 30.2 in Fig. 9, und auch breiter als die abgefälzte Partie 41.1. Bei gleicher Form der Keilverzinkung 32, 33, 34 ergibt sich damit in den Partien 40.1 und 40.2 an den freien Enden der bogenförmigen Abschnitte 32 und 33 jeweils ein Absatz 42 bzw. 43.10 shows the same representation as 9 shows an end section of a dividing element 40 and a portion of a frame leg (or other Subdivision element) 41. The frame leg 41 has a rebated section 41.1, and the dividing element 40 has rebated sections 40.1 and 40.2 on both sides. The parts shown in Fig. 10 differ from those shown in Fig. 9 only in that the Fig. 10 rebated sections 40.1 and 40.2 of the subdivision element 40 are wider than the rebated sections 30.1 and 30.2 in Fig. 9, and also wider than the rebated section 41.1. With the same shape of the finger jointing 32, 33, 34 results in games 40.1 and 40.2 on the free ends of the arcuate portions 32 and 33, respectively a paragraph 42 or 43.
