Description
Aus Rohren gebildete Eckverbindung. Gegenstand vorliegender Erfindung ist eine neuartige, aus Rohren gebildete Eck- verbindung, die insbesondere -bei der Massen fabrikation mit Vorteil zur Anwendung kommt, z. B. bei der Herstellung von Mö beln, Gestellen, Bettstellen usw.
Die neue Eckverbindung ermöglicht mit wenigen Teilen eine zuverlässige und auch für hohe Beanspruchungen geeignete Eck- verbindung aus Rohren zu schaffen. Die Ein zelteile können in Serien leicht genau und auswechselbar hergestellt werden, so dass die Herstellung der Eckverbindung keine Nach arbeit und wenig Zeit beansprucht.
In der Zeichnung sind zwei Ausführungs beispiele des Erfindungsgegenstandes dar gestellt; es zeigt: Fig. 1 eine Eckverbindung eines Rohres mit drei aneinanderstossenden Rohren von gleichem Durchmesser in Ansicht unter Weg lassung des nach vorn gerichteten Rohres; Fig. 2 ist ein Schnitt nach der Linie II-II der Fig. 1, Fig. 3 ,eine Eckverbindung mit schräg ge stellten Rohren.
Mit einem Rohr 1 (Fig. 1 und 2) sind drei Rohre 2, 3 und 4 von gleichem Durchmesser verbunden. Zur Verbindung dienen drei Pass- stücke 5, 6, 7, die alle gleich geformt sind und gleiche Abmessungen besitzen. Jedes Passstück besitzt einen Schaft 8, der gut passend in einem Rohr 2, 3, 4 sitzt; ferner einen Kopf 9, dessen Durchmesser dem Aussendurchmesser des Rohres 2, 3, 4 ent spricht. Auf der Stirnseite besitzt der Kopf 9 eine zylindrische Ausnehmung, deren Radius dem Aussendurchmesser des Rohres 1 ent spricht.
Die Passstücke 5, 6 und 7 besitzen Bohrungen 11, durch welche Schraubenbolzen 13 bezw. 14, beide von gleichem Durchmesser, geführt sind. Die Bolzen 13 und 14 sind da bei durch Bohrungen des Rohres 1 geführt. Im Innern des Rohres 1 sitzt gut passend ein Kern 15 mit einer durchgehenden Bohrung 16, in welcher der Gewindebolzen 13 sitzt.
Mit an seinen beiden Enden vorgesehenen Muttern 17 werden die den Bolzen 13 um- fasenden Passstücke 5 und 7 an das Rohr 1 angepresst. In einer Querbohrung 18 des Kernes 15 ist der Gewindebolzen 14 ein geschraubt.; eine an diesem vorgesehene Mutter<B>19</B> presst das Passstüek 6 an das Rohr 1.
Die Rohre 2, 3, 4 sitzen passend auf den Schäften der Passstücke 5, Ei, 7; sie sind mit Nieten 20, die in Löcher 21 der Passstüeke eingrleifen, gesichert.
Die neue Eel@verbindung kann bei Rohren mit beliebigem Querschnitt, z. B. elliptisebexn, viehekigen2 Querschnitt Anwendung finden. Die Eekverbindung ist eine starre. Da die dar"-estellten Passstücke, die Bolzen und Muttern alle unter sich gleich sind, wird die Ecl@verbindun- in der Ilerstelhing sehr billig.
Die an das Rohr 1 anzuschliessenden Rohre können auch in einem andern als rechten 'X'inkel zueinander Stehen, soweit dies die jeweiligen Abmessungen der Rohre erlauben. Ferner können die am Rohr 1 zu befestigen den Rohre, wie Fig. 3 zeigt, in bezug auf ersteres schräg gestellt sein und unter sich einen beliebigen Winkel einschliessen.
Corner connection formed from tubes. The subject matter of the present invention is a new type of corner connection formed from tubes, which is particularly useful in mass production, e.g. B. in the manufacture of furniture, frames, bedsteads, etc.
The new corner connection makes it possible to create a reliable corner connection from pipes that is also suitable for high loads with just a few parts. The individual parts can easily be produced precisely and interchangeably in series, so that the production of the corner connection requires no rework and little time.
In the drawing, two execution examples of the subject invention are provided; 1 shows a corner connection of a tube with three mutually abutting tubes of the same diameter in view, omitting the forwardly directed tube; Fig. 2 is a section along the line II-II of Fig. 1, Fig. 3, a corner connection with obliquely ge placed pipes.
With a pipe 1 (Fig. 1 and 2) three pipes 2, 3 and 4 of the same diameter are connected. Three fitting pieces 5, 6, 7 are used for the connection, all of which are shaped identically and have the same dimensions. Each fitting piece has a shaft 8 which fits snugly in a tube 2, 3, 4; also a head 9, the diameter of which corresponds to the outer diameter of the pipe 2, 3, 4 ent speaks. On the front side, the head 9 has a cylindrical recess, the radius of which corresponds to the outer diameter of the pipe 1 ent.
The fitting pieces 5, 6 and 7 have holes 11 through which screw bolts 13 respectively. 14, both of the same diameter, are guided. The bolts 13 and 14 are there passed through holes in the tube 1. A core 15 with a through hole 16 in which the threaded bolt 13 is seated fits well inside the tube 1.
With nuts 17 provided at its two ends, the fitting pieces 5 and 7 surrounding the bolts 13 are pressed onto the pipe 1. In a transverse bore 18 of the core 15, the threaded bolt 14 is screwed; a nut <B> 19 </B> provided on this presses the fitting piece 6 onto the pipe 1.
The tubes 2, 3, 4 fit snugly on the shafts of the fitting pieces 5, egg, 7; they are secured with rivets 20, which grind into holes 21 of the fitting pieces.
The new Eel @ connection can be used for pipes with any cross-section, e.g. B. elliptisebexn, viehekigen2 cross-section application. The eek connection is a rigid one. Since the fittings shown, the bolts and nuts are all the same, the Ecl @ connection is very cheap in the Ilerstelhing.
The pipes to be connected to the pipe 1 can also be at an angle other than right 'X' to one another, provided the respective dimensions of the pipes permit. Furthermore, the tubes to be attached to the tube 1, as shown in FIG. 3, can be inclined with respect to the former and include any angle below.
