Abstract

The design overcomes the difficulty that the required holding properties of normal woodscrews and fastenings are reduced as the wood dries out. It also fixes securely components with small wall thickness. The screw has specified holding properties. It consists of a tubular sleeve with an internal thread in a blanked off hole and a countersunk screw head. The screw fitting in the other side holds the elements together. The first screw which is slightly tapered has a screw thread on its outer surface. An additional design has a normal screw head instead of the counter sunk head.

Description

Koppelschraubenelement Die Neuerung betrifft ein Koppelschraubenelement zum exakten zug - scher und druckfesten Koppeln von Elementen aller Art. Coupling screw element The innovation relates to a coupling screw element for the exact tensile and pressure-resistant coupling of all kinds of elements.

Bekannt sind Holzschrauben, Zylinderschrauben, Madenschrauben in vielen Variationen, welche nach DIN genormt sind.Wood screws, cylinder screws, grub screws are known in many Variations, which are standardized according to DIN.

Die bekannten Schrauben haben den Nachteil, dass sie beispielsweise zum Verbinden von Holzelementen durch Eintrocknen des Holzes nicht mehr die erwünschte Zug,-Scher und Druckaufnahmeeigenschaften besitzen. Sie haben weiter den Nachteil, dass beim Koppeln von Elementen mit geringen Wandstärken eine einwandfreie Verbindung nicht gegeben ist.The known screws have the disadvantage that they, for example for connecting wooden elements due to drying of the wood no longer the desired one Have tensile, shear and pressure absorption properties. You also have the disadvantage that when coupling elements with thin walls, a perfect connection is not given.

Der Neuerung liegt die Aufgabe zugrunde, ein Koppelschraubenelement dem Handwerker in die Hand zu geben, welches die angezeigten Mängel nicht aufweist. Es soll Elemente mit exakter Sicherheit koppeln.The innovation is based on the task of a coupling screw element to hand over to the craftsman who does not have the reported defects. It is supposed to couple elements with exact security.

Die Aufgabe wird nach der Neuerung wie folgt gelöst: Man nehme eine Rohrhülse mit herkömmlichem Schraubengopf und versehe sie mit einem Sacklochgewinde,als Konterstück dient eine herkömmliche Schraube mit gewtinschtem Schraubenkopf.According to the innovation, the task is solved as follows: Take one Pipe sleeve with a conventional screw head and provide it with a blind hole thread, as The counter piece is a conventional screw with a desired screw head.

Ein Ausführungsbeispiel zeigt die Zeichnung Fig. 1 zeigt eine Rohrhülse 1 mit Sacklochinnengewinde zur Aufnahme einer handelsublichen Konterschraube 2.An exemplary embodiment is shown in the drawing. FIG. 1 shows a tubular sleeve 1 with internal blind thread to accept a commercially available counter screw 2.

Die Rohrhülse ist mit einem beliebigen Schraubenkopf auszubilden. The tubular sleeve can be designed with any screw head.

Pig. 2 zeigt ausschnittsweise den Mittelpfosten 4 eines zweiflügeligen Fensters mit Verriegelungsblechen 3, welche durch eine Rohrhülse mit Sacklochinnengewinde 5 und Konterschraube 2 eine exakte Halterung erfährt.Pig. 2 shows a detail of the center post 4 of a two-winged one Window with locking plates 3, which through a tubular sleeve with a blind hole thread 5 and counter screw 2 experiences an exact mounting.
