Die vorliegende Neuerung besteht darin, dafs ; aus Blechstreifen röhrenförmig gebogene Stangen im Innern Versteifungsrippen haben, die dieselben vor Zusammendrücken schützen. Infolge dessen kann man diese röhrenförmigen Stangen auch speciell in der Ebene der ι Symmetrielinie ihres Querschnittes biegen, ohne dafs sich die Querschnittsform wesentlich verändert, während man bekanntlich vollständig hohle Röhren aus schwachem Blech zu diesem Zwecke vorher mit leicht flüssigem Metall, Pech, heifsem Sand etc. ausfüllen mufs.The present innovation consists in the fact that; Tubular bent rods made of sheet metal strips have stiffening ribs on the inside, which protect them from being compressed. As a result, you can get these tubular Bend rods especially in the plane of the symmetry line of their cross-section without that the cross-sectional shape changes significantly, while one is known to be complete hollow tubes made of weak sheet metal for this purpose beforehand with slightly liquid metal, Pitch, hot sand etc. have to fill in.
Aus diesem Umstände geht die vortheihafte Verwendung dieser Neuerung für die verschiedensten Zwecke der Blech- und Metallwaarenindustrie, wie sie die beiliegende Zeichnung beispielsweise andeutet, hervor.It is from these circumstances that this innovation can be used advantageously for the most varied of purposes Purposes of the sheet metal and metal goods industry, as indicated in the accompanying drawing, for example.
Fig. I bis V zeigen die verschiedenen Querschnitte für die verschiedenen Arten der An Wendung und die verschiedenen Lagen der Versteifungsrippen.Fig. I to V show the different cross-sections for the different types of An Twist and the different layers of stiffening ribs.
Fig. I zeigt den Querschnitt als rundes Rohr, welches durch Löthung an der Stelle α leicht geschlossen werden kann.Fig. I shows the cross section as a round tube, which can be easily closed by soldering at the point α.
Fig. II und III zeigen passende Querschnitte für hohle Handgriffe etc.Fig. II and III show suitable cross-sections for hollow handles etc.
Fig. IV zeigt einen passenden Querschnitt als Reifen für Fässer, Kasten und Koffer.Fig. IV shows a suitable cross section as a tire for barrels, boxes and cases.
Fig. V zeigt den Querschnitt als Reifen oder Schutzleiste um die Kanten von Fässern, Kasten und Koffern.Fig. V shows the cross section as a tire or protective strip around the edges of barrels, boxes and suitcases.
Um die Biegungen dieser röhrenförmigen Stangen anzudeuten, zeigen Fig. 1 bis 6 Biegungen bei Gefäfshenkeln und Handgriffen, Fig. 7 bei zusammenstofsenden Reifen, Fig. 8 und 9 beim Verstärkungswulst um Badewannen etc., Fig. 10 bei der Rücklehne eines Gartenstuhles und Fig. 1 1 und ι 2 bei Verstärkungsrippen um Kanten und Rümpfe von Fässern, Kasten und Koffern.To indicate the bends of these tubular rods, Figures 1 to 6 show bends with vessel loops and handles, Fig. 7 with cohesive tires, Figs. 8 and 9 with Reinforcement bead around bathtubs etc., Fig. 10 in the backrest of a garden chair and Fig. 1 1 and ι 2 with reinforcement ribs around edges and Hulls of barrels, boxes and suitcases.
