Abstract

The double-acting screw (4) enables two profiles to be drawn together by turning at any wrench attachment point (6) and two profiles to be pressed apart by turning in the opposite direction. The distance from the inside of the screw head (1) to the start of the securing ring (2) corresponds to the thickness of one profile. The thread (5) is smaller than the screw head (1). The securing ring (2) is pushed onto the available groove (3) after screw assembly. A splint, R-clip, grub screw or the like, depending on the required pressure effect, can be used instead of the securing ring (2).

Description

Die Erfindung betri fft eine doppeltwirkende Schraube, insbesondere zur Montage von Zaunelementen . The invention relates to a double-acting screw, particularly for assembling fence elements.
Schrauben sind in unterschiedlichen Aus führungen bekannt . Als nachteilig erweist sich, dass 2 Profile nur zusammengezogen werden können und nicht auseinandergedrückt werden können . Möchte man zum Beispiel ein Brett zwischen einen Spalt zweier Profile , der 20 mm misst , schieben und dieses Brett ist außer der Toleranz und misst 20 , 2 mm, ist es nicht möglich dieses Brett in den Spalt der Profile zu schieben . Dieses Brett nachzubearbeiten würde zeitaufwendig sein und hohe Kosten verursachen . Des Weiteren werden bei engen Montagetoleranzen oft beschichtete Teile zerkratzt , was dem Kunden sofort ins Auge fällt . Screws are known in different designs. The disadvantage is that 2 profiles can only be pulled together and cannot be pushed apart. For example, if you want to push a board between a gap between two profiles that measures 20 mm and this board is out of tolerance and measures 20.2 mm, it is not possible to push this board into the gap of the profiles. Refinishing this board would be time-consuming and costly. Furthermore, with tight assembly tolerances, coated parts are often scratched, which is immediately noticeable to the customer.
Der Erfindung liegt demnach die Aufgabe zugrunde , eine Schraube , eingangs erwähnter Art , so zu verbessern, dass die oben erwähnten Nachteile nicht zum Tragen kommen . The invention is therefore based on the object of improving a screw of the type mentioned at the beginning in such a way that the disadvantages mentioned above do not come into play.
Das wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruch 1 erreicht . Weitere vorteilhafte Ausgestaltungen werden gemäß den Unteransprüchen vorgeschlagen . Die Erfindung wird nun unter Bezugnahme auf ein Aus führungsbeispiel , welches in der Zeichnung schematisch dargestellt ist , weiter erläutert . This is achieved according to the invention by the characterizing features of claim 1. Further advantageous refinements are proposed according to the subclaims. The invention will now be further explained with reference to an exemplary embodiment which is shown schematically in the drawing.
Es ist Ziel , Schrauben so anzufertigen, dass diese doppeltwirkend sind, dass man 2 Profile durch Anziehen der Schraube zusammenziehen und durch Drehen auf die Gegenseite auseinanderdrücken kann . The aim is to make screws so that they are double-acting, so that two profiles can be pulled together by tightening the screw and pushed apart by turning them to the opposite side.
Es ist daher vorteilhaft bei der Schraube eine Nut zu fertigen, bei der man einen Sicherungsring drauf schieben kann . Der Abstand von Innenseite Schraubenkopf bis Anfang Nut entspricht der Stärke eines Profils . Je nach Bedarf des Auseinanderdückens kann auch ein Durchgangsloch bei der Schraube mit Splint , Federstecker oder dergleichen die Druckwirkung erreicht werden . It is therefore advantageous to make a groove in the screw so that you can slide a locking ring onto it. The distance from the inside of the screw head to the start of the groove corresponds to the thickness of a profile. Depending on the need for pushing apart, a through hole in the screw with a cotter pin, spring pin or similar can also be used to achieve the pressure effect.
Fig . 1 zeigt die Draufsicht der doppelwirkenden Schraube . Fig. 1 shows the top view of the double-acting screw.
Der Abstand von Innenseite des Schraubenkopf 1 bis zum Anfang Sicherungsring 2 entspricht der Stärke von dem zu montierenden Profil . Der Sicherungsring 2 wird auf die passende Nut 3 nach der Montage j ener doppelwirkenden Schraube 4 geschoben . Das Gewinde 5 hat einen kleineren Durchmes ser als Schraubenkopf 1 . Durch mehrere Schlüsselansätze 6 wird ermöglicht , an verschiedensten Positionen durch Drehen derj enigen Schraube zwei Profile zusammenzuziehen oder durch Drehen in die gegenseitige Richtung zwei Profile auseinanderzudrücken . The distance from the inside of the screw head 1 to the start of the locking ring 2 corresponds to the thickness of the profile to be mounted. The locking ring 2 is pushed onto the appropriate groove 3 after installing the double-acting screw 4. The thread 5 has a smaller diameter than the screw head 1. Several key lugs 6 make it possible to pull two profiles together or through them at various positions by turning the screw Rotate in the mutual direction to push two profiles apart.
