Description

Dübel zur festen Verbindung von Holzteilen Die Neuerung betrifft Dübel, um Holzteile fest miteinander zu verbinden. Diese Holzteile können verschiedenster Art sein und z. B. Teile von Möbelstücken o. dgl. oder auch Leitern mit Stufen oder Sprossen oder sonstige andere Holzwaren sein.Dowels for the fixed connection of wooden parts The innovation relates to dowels, to firmly connect wooden parts together. These wooden parts can be of the most varied Be kind and z. B. parts of furniture o. The like. Or ladders with steps or Be sprouts or other other wooden products.

Es ist üblich, Holzteile in unterschiedlichster Weise miteinander zu verbinden, wobei auch an einem Teil befindliche zylindrische Zapfen verwendet werden, die ggf. am äusseren Ende mit Hilfe eine Keils aufgetrieben werden, um das betreffende Ende in dem Zapfenloch fest einzuspannen. Diese Zapfen sind mitunter z. B. auch bei Leitern an einem der beiden Holzteile, im Falle der Leiter an der Stufen, angefräst. Bei Leitern ist es weiterhin üblich, die. Stufen beiderseits in flache Nuten der seitlichen Holme einzusetzen und mit Schrauben zu befestigen. Dies hat aber den Nachteil ? dass derart ausgebildete Leitern bereits nach kurzem Gebrauch wackeln, da sich durch das Nachtrocknen des Holzes die Ver- bindungen lockrn ßo dass der ursprünglich einmal vorhanden gewesenefeste Zueaumenhalt nicht mehr gegeben ist. Zur Vermei- dung dieser Nachteile hat man bei Leitern die Stufen mit Zapfen vayseent dann in den Holmen von auesen verkeilt werden. Se hat eich aber gezeist, 4ass auch diese Befestigung zweier Miteinander su verbindender Rolsteile, nämlich der Stufen mit ea Holmen, ungeeignet ist$ a die Holzkeile bei der Herstellung von den zumeist im Akkord beschäftigen Arbeiter zu kräftig eingescMagen werdent so aße höhere Spannungen auftreten, als erwünscht und zulässig iNt, eo dass die Helme an den Zapfstellen ein-bzw. längs aufeissen Um die Mängel der bekannten Befestigungsmittel zu vermeiden, wird neuerungegemuca vorgeschlagen. t' feste Verbindung zweier Holzteile einen Dübel zu verwenden, der einen verzugs- weise konißenen Kopf besitzt, welcher in iner konischen Bo3u*ung des einen zu verbindenden Halsteils liegt und der einen an den Xopf anschliessendent zylindrischen Schaft besitzt, der in eine tylindrische Bohrung den anderen'Rolzteils eingeleimt ist und der an seinem inneren Ende mit einem Schlitz versehen ist, in welchenein sioh sm Grund der Bohruuij abstützender Keil ein- greift und die Enden den Dttbele auievreizt =d gegen die Wand der Bohrung anpresst. Der konische Kopf des neuerungegsmäss. ausgebildeten Dübels bietet den gyoesen Vorteil, dass in den einender beiden zu verbindenden Holzteile nur eine kleine konische Bohrung anstelle ises grossen Zapfenloches angebracht zu werden braucht, wodurch die Schwächung dieses Holzteils so gering wie nur möglich gehalten wird. Die Länge des Dübel-Schaftes richtet sich zweckmäasig nach den jeweiligen Verhält- nissen, ebenso die Länge des Schlitzes am Ende des zylindri- schen Dübelschaftes, der im übrigen der Aufnahme überschüssigen Leims dient. Durch den in den Schlitz eindringenden Keil wird die Festigkeit des Sitzes des Zapfens im Dübelloch an der hintersten tiefsten Stelle vergrSssert, so dass die mit den neuerungegeaäseen Dübeln erfolgte Verbindung von Holzteilen besonders dauerhaft und haltbar ist.It is customary to connect wooden parts to one another in a wide variety of ways, with cylindrical pegs located on one part also being used which, if necessary, are driven on at the outer end with the aid of a wedge in order to clamp the end in question firmly in the mortise. These cones are sometimes z. B. also with ladders on one of the two wooden parts, in the case of the ladder on the steps, milled. In the case of ladders, it is still common practice to use the. Insert the steps into the shallow grooves on both sides of the side rails and fasten them with screws. But does this have the disadvantage? that ladders designed in this way already after a short period of use wobble, as the drying of the wood causes the bindings lockrn so that the originally once existed which have been fixed is no longer given. To avoid As a result of these disadvantages, ladders have steps with tenons vayseent can then be wedged in the spars of auesen. But he has shown that this attachment of two With each other su connecting roll parts, namely the steps with ea spars, unsuitable is $ a the wooden wedges in the manufacture too vigorous by the mostly piecework workers This means that higher tensions will occur than desirable and permissible iNt, eo that the helmets at the filling points on or. tear open lengthways In order to avoid the shortcomings of the known fasteners, is proposed neuerungegemuca. t 'fixed connection to use a dowel between two wooden parts, which wise conical head, which has a conical shape of the one to be connected neck part and the one to the Xopf then has a cylindrical shaft, which is in a cylindrical bore is glued to the other part of the wood and which is provided with a slot at its inner end, in which a wedge supporting the Bohruuij grips and expands the ends of the dttbele = d against the wall pressed against the hole. The conical head of the novelty. trained dowel offers the gyoesen advantage that in the one of the two wooden parts to be connected only a small one conical hole instead of a large mortise needs to be, whereby the weakening of this wooden part is kept as low as possible. The length of the dowel shaft is appropriately based on the respective nits, as well as the length of the slot at the end of the cylindrical rule's dowel shaft, which is also used to absorb excess glue. Due to the wedge penetrating into the slot, the firmness of the seat of the pin in the dowel hole is increased at the deepest point, so that the connection of wooden parts made with the newly developed dowels is particularly durable and durable.

Ein weiterer Vorteil ergibt eich daraus, dasa bei den Verbindungen Material insofern eingespart werden kann, als es nicht Mehr notwendig ist, das zwischen den Zapfen befindliche Nelz zu entfernen, um die als Verbindungsmittel dienenden Zapfen irorstehen zu lassen, In der Zeichnung ist der Gegenstand der Neuerung anhand eines- bevorzugten Ausführungsbeispiels dargestellt. Die ZeiChnung stellt einen Schnitt durch zwei zu verbindende Holzteilen bei- spielsweise den Seitenholm einer Leiter und deren Stufen dar, die mit Hilfe der neuerungegemässen Dübel miteinander ver- zapftsind. In dem Leiterholm 1 befindet sich die flache Nut 29 in die das Stufenbrett 3 mit seiner StirnseitJeingesetzt iet. In der Mitte der Nut 2 befinden sichtbar die Breite des Leiterholms 1 verteilt, mehrere konische Zapfenlöcher 5t in denen der konische Sßr 6 7 l BBen de tiMRQltE de n 5 Kopf 6 das DU, bels 7 liegt, dessen zylindrisoher sohaft 8 in der zylindrischen Bohrung 9 in der Stirnselte der Stufen 3 liegt, Das innere Ende des zylindrischen Schetes 8 des Dübels ist mit einem Schlitz 10 versehen, in den der Keil 11 eingreift. der sich am Grund 12 der Bohrung 9 abstützt. Der Dübel 7 wird sorswgeseste au ! r ggans en beidena.'varMn'ienäea.

A further advantage results from the fact that material can be saved in the connections insofar as it is no longer necessary to remove the fur located between the pegs in order to allow the pegs serving as connecting means to protrude. In the drawing, the subject matter of Innovation based on Preferred embodiment shown. The drawing provides a cut through two pieces of wood to be connected. for example the side rail of a ladder and its steps, which are connected to each other with the help of the new dowels are tapped.
