Description
Doppelschwalbenschwanzförmiger Dübel zur Verbindung von anelnanderliegenden Bauteilen. Gegenstand der Erfindung ist ein zur Verbindung von Holzteilen dienender Dübel, welcher in vorgebohrte Löcher der Hölzer eingeführt wird. Der Dübel besteht aus zwei Holzkeilen, deren innere Flächen konkav ausgebildet sind, und einer diese umgebenden Blechhülse mit Längsschlitzen an den Enden und mit nach außen vortretenden, entgegen der Eintreibrichtung gerichteten Zacken. Die Bohrungen in, den Hölzern sind nach den von den Berührungsßächen der Hölzer weg gerichteten Enden verbreitert, und die Holzkeile sind je an einem Ende verstärkt, entsprechend dieser Verbreiterung der Bohrung.Double dovetail-shaped dowel for connecting adjacent ones Components. The invention relates to a connecting piece of wood Dowel, which is inserted into pre-drilled holes in the wood. The dowel is made of two wooden wedges, the inner surfaces of which are concave, and one of these surrounding sheet metal sleeve with longitudinal slots at the ends and with protruding, prongs directed against the driving direction. The holes in, the woods are widened towards the ends directed away from the contact surfaces of the wood, and the wooden wedges are each reinforced at one end, corresponding to this widening the hole.
Zur Herstellung der Verbindung wird in die Bohfung zunächst die Blechhülse eingeführt und dann die Keile, und. zwar so, daß nach jeder der verbreiterten Lochenden hin je ein verstärktes Keilende zu liegen kommt. Durch Druck oder Schlagwirkung werden die Keile in die Hülse fest eingetrieben. Die konkaven Inneni1ächen der Keile legen sich dabei aufeinander, die verdir-kten Keilendten spreizen die geschlitzten Hülsenenden. auseinander und geben so dem ganzen Dübel die doppelte Schwalbensehwanzform, und die Zacken der Hülse dringen in die Lochwandung ein.To establish the connection, the sheet metal sleeve is first inserted into the hole inserted and then the wedges, and. so that after each of the widened hole ends a reinforced wedge end comes to rest. By pressure or impact the wedges are firmly driven into the sleeve. The concave inner surfaces of the wedges lie on top of one another, the twisted wedge ends spread the slit ones Sleeve ends. apart and give the whole dowel the double dovetail shape, and the prongs of the sleeve penetrate the wall of the hole.
