Description

Bei der Herstellung billiger Stahlrohrmöbel werden häufig Holzplatten, so z. B. als Stuhlsitze, verwendet, die aus Preisrücksichten nicht aus kreuzweise verleimten Furnieren hergestellt werden können. Dem sogenannten Arbeiten dieser nicht abgesperrten Holzplatten muß man bei der Befestigung auf den Stahlrohren Rechnung tragen. Dies geschah in der Weise, daß man in die Holzplat- «o ten ζ. B. zwei schwalbenschwanzförmige Nuten senkrecht zur Faserrichtung einfräste, ■die Stahlrohre entsprechend formte, in diese Nuten einschob und mit der Holzplatte verschraubte. Hierbei wurden die Nuten länger ausgeführt, als die Länge der eingeschobenen Stahlrohre beträgt, um dem Holz die Möglichkeit der Bewegung zu geben und hierdurch die Bildung von Trockenrissen zu vermeiden. Die in die Nuten eingeschobenen Stahlrohre hinderten dabei gleichzeitig das Werfen des Holzes. Durch das Arbeiten des Holzes verloren jedoch die Stahlrohre in den Nuten allmählich ihren festen Halt.In the manufacture of cheap tubular steel furniture, wooden panels are often used, e.g. B. as Chair seats, used, which for price considerations are not made of cross-glued veneers can be produced. The so-called work of these wooden panels that are not locked off must be taken into account when fastening take the steel pipes into account. This was done in such a way that one «O ten ζ. B. mill two dovetail grooves perpendicular to the grain direction, ■ shaped the steel pipes accordingly, pushed them into these grooves and screwed them to the wooden plate. The grooves were made longer than the length of the inserted steel tubes to give the wood the opportunity to give movement and thereby avoid the formation of dry cracks. The ones pushed into the grooves At the same time, steel pipes prevented the wood from being thrown. By working the However, the steel pipes gradually lost their firm hold in the grooves of wood.

Dieser Übelstand wird erfindungsgemäß in einfachster Weise dadurch behoben, daß man das Arbeiten der Holzplatte beim Trocknen dazu benutzt, um die in die Nuten eingeschobener Stahlrohre z. B. mittels Keiles auseinanderzutreiben und in den Nuten festzuklemmen. This drawback is remedied in the simplest way according to the invention that one the work of the wooden panel during drying is used to remove the inserted into the grooves Steel pipes z. B. to drive apart by means of a wedge and to clamp it in the grooves.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar; und zwar zeigtThe drawing shows an embodiment of the invention; namely shows

Abb. ι einen Stuhlsitz oder eine Tischplatte von unten gesehen,Fig. Ι a chair seat or a table top seen from below,

Abb. 2 ein der Nut entsprechend geformtes Befestigungsrohr undFig. 2 a correspondingly shaped fastening tube and the groove

Abb. 3 dasselbe mit eingeschobenem Keil.Fig. 3 the same with the wedge inserted.

Die Rohre c, auf denen die mit quer zur Faserrichtung des Holzes verlaufenden Nuten b versehene Holzplatte α befestigt werden soll, sind der Nut entsprechend geformt und erhalten Längsschlitze f. In die Rohre c werden die Keile d (Abb. 3) so eingetrieben, daß sie über die Stahlrohre hervorstehen, die verlängerten Nuten aber voll ausfüllen. Die Wirkungsweise ist nun derartig, daß beim Zusammentrocknen des Holzbrettes, also bei dem sogenannten Schwinden, der Keil d (Abb. 1) senkrecht zur Faser des Brettes in das bei g mit der Platte α verschraubte Stahlrohr c hineingetrieben wird. Dadurch wird das geschlitzte Rohr etwas auseinandergetrieben und bewirkt damit selbsttätig einen dauerhaften, festen Sitz der Holzplatte auf dem Stahlrohr.The tubes c, on which the wood plate α provided with grooves b running transversely to the grain of the wood is to be fastened, are shaped to correspond to the groove and contain longitudinal slots f. The wedges d (Fig. 3) are driven into the tubes c in such a way that they protrude over the steel tubes, but completely fill the elongated grooves. The mode of operation is now such that when the wooden board dries together, i.e. during the so-called shrinkage, the wedge d (Fig. 1) is driven perpendicular to the fiber of the board into the steel tube c screwed to the plate α at g . As a result, the slotted tube is driven apart a little and thus automatically ensures that the wooden plate sits firmly and permanently on the steel tube.
