Description
Fachwerk, z. B. für Gerüste Das Patent hat zum Gegenstand ein Fach werk mit einer vorteilhaften Verbindung der Einzelteile beispielsweise zu einem Gerüst, Bauwerk, Lagergestell, Spielzeug.
Die erfindungsgemässe Verbindung erlaubt bei geeigneter Bemessung der Teile ausser ordentlich stabiles Zusammenfügen der Einzel teile und rasche Montage und Demontage der selben.
Die Zeichnung zeigt an einem Beispiel die Elemente des Fachwerkes, die Streben und Knotenkörper, in Ansichten und Schnitten.
Die Knotenkörper 1 sind gebildet durch hohlkugelartige Körper, z. B. aus Eisen, Stahl, Pressstoff usw., mit einer nach Bedarf gewähl ten Zahl zylindrischer, radialer Bohrungen 2, die senkrecht und unter 45 zueinanderstehen.
Die in verschiedenen Längen vorgesehenen Streben aus entsprechenden Rohren haben an jedem Ende Spreng- oder Expansionszapfen 3, die in die Bohrungen der Knotenkörper ein zusetzen und darin festklemmbar sind. Zu diesem Zwecke sind an den Rohrenden 4 der Strebenrohre 5 je ein Zapfen 6 aus Stahl an gebracht, der einen Gewindebolzen 7 mit Fein gewinde besitzt. Auf diesen ist eine Messing mutter angebracht, die eine konische Aussen fläche 9 besitzt, wobei der Anzug gegen die Strebe zu verläuft. Auf dieser Mutter ist ein Spreizring 10 aus gehärtetem Stahl aufgesetzt, dessen innere Fläche 11 passend konisch ist.
Der Spreizring weist axiale, abwechselnd vom einen und andern Ende ausgehende Schlitze 1.2 auf. Die Aussenfläche ist zylindrisch und geriffelt in der Grösse der Bohrung 2 der Knoten.
Durch Drehen der Strebe 5 im einen Sinne und damit des Zapfens 7 schiebt- sich die Konusmutter 9 in den Spreizring 10 hinein und vergrössert seinen Durchmesser bis zum satten Festklemmen in der Bohrung 2. Zur Erleichterung des Spreizens ist am Zapfen 6 eine konische Schulter 13 und am Spreizring ein ebensolcher Sitz vorgesehen.
Die Grifflöcher 14 dienen zum Einstecken eines Werkzeuges, z. B. eines Dornes oder Schlüssels zum Drehen der Strebe.
Das andere Ende der Strebe ist ähnlich ausgebildet mit dem Unterschied, dass der Zap fen 15 im Rohr 5 drehbar ist. Ein Arretie- rungsring 16 kann verhindern, dass der Zapfen herausfällt.
Beide Gewindebolzen 7 haben das gleiche Gewinde und sind gegeneinander verdrehbar; es können aber auch je ein Rechts- und ein Linksgewinde vorgesehen werden.
An die Knotenkörper können auch Fahr rollen und andere Zubehöre befestigt werden. Grundsätzlich können diese Fachwerkele- mente für jeden geeigneten Zweck verwendet werden, in leichterer Ausführung unter an derem auch für Bauspielzeuge.
Truss, e.g. B. for scaffolding The subject of the patent is a framework with an advantageous connection of the items, for example, to a scaffolding, structure, storage rack, toys.
With a suitable dimensioning of the parts, the connection according to the invention allows apart from neatly stable joining of the individual parts and rapid assembly and disassembly of the same.
The drawing shows an example of the elements of the framework, the struts and node bodies, in views and sections.
The node body 1 are formed by hollow spherical bodies, for. B. made of iron, steel, pressed material, etc., with a number of cylindrical, radial bores 2, which are perpendicular and under 45 to each other, as required.
The struts provided in different lengths from corresponding tubes have detonation or expansion pins 3 at each end, which insert into the bores of the node body and can be clamped therein. For this purpose, a pin 6 made of steel are placed at the tube ends 4 of the strut tubes 5, which has a threaded bolt 7 with fine thread. On these a brass nut is attached, which has a conical outer surface 9, the suit running against the strut. An expansion ring 10 made of hardened steel is placed on this nut, the inner surface 11 of which is appropriately conical.
The expansion ring has axial slots 1.2 extending alternately from one end and the other. The outer surface is cylindrical and corrugated the size of the hole 2 of the node.
By turning the strut 5 in one direction and thus the pin 7 pushes the conical nut 9 into the expansion ring 10 and increases its diameter until it is firmly clamped in the bore 2. To facilitate the spreading, a conical shoulder 13 and is on the pin 6 Such a seat is provided on the expansion ring.
The handle holes 14 are used to insert a tool, for. B. a mandrel or key for turning the strut.
The other end of the strut is designed similarly with the difference that the Zap fen 15 in the tube 5 is rotatable. A locking ring 16 can prevent the pin from falling out.
Both threaded bolts 7 have the same thread and can be rotated against each other; however, a right-hand and a left-hand thread can also be provided.
Castors and other accessories can also be attached to the node body. In principle, these truss elements can be used for any suitable purpose, in a lighter version also for building toys.
