KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Es ist an sich bekannt, Isolierröhren für elektrische Leitungen, besonders solche, die unter Verputz verlegt werden, durch Deckleisten aus Eisen zu schützen. Diese Deckleisten sollen insbesondere das Eintreiben von Nägeln in die Röhren verhindern. Es ist ferner bekannt, zum gleichen Zwecke die Ecken und Biegungen solcher Isolierröhren mit in einem beliebigen Winkel einstellbarenIt is known per se, insulating tubes for electrical lines, especially those that laid under plaster, protected by cover strips made of iron. These cover strips in particular are intended to prevent nails from being driven into the tubes. It is also known, for the same purpose, the corners and bends of such insulating tubes with adjustable at any angle
ίο 'Stücken eines Metallschlauches zu umhüllen. Gegenstand der Erfindung ist ein Schutzstück, welches ebenso wie der erwähnte Metallschlauch die Ecken und Biegungen der" Isolierröhren schützen soll, gegenüber dieser älteren Einrichtung aber den Vorteil bietet, daß es über den zu schützenden Stellen an-' gebracht und bequem \vieder entfernt werden kann, wenn die Isolierröhren fertig verlegt sind. Die Metallschläuche haben einen geschlossenen, ringfertigen Querschnitt und sie können daher nur von einem Ende der elektrischen Leitung aus über "dieselbe geschoben werden. Das nachträgliche Anbringen eines solchen Schutzstückes an vorhandenen Leitungen macht demnach· stets eine Öffnung derselben notwendig und auch die Verlegungίο 'to enclose pieces of a metal hose. The subject of the invention is a protective piece which, like the aforementioned metal hose, clears the corners and bends of the " To protect insulating tubes, but has the advantage over this older facility, that it can be placed over the areas to be protected and conveniently removed again can when the insulating tubes have been laid. The metal hoses have a closed, ring-ready cross-section and they can therefore only from one end of the electrical Line can be pushed out over the same. The subsequent attachment of such a protective piece to existing lines therefore · always requires an opening of the same and also the relocation
■ neuer Leitungen ist mühevoller, weil die Schlauchstücke vor dem Verlegen über die . Leitung geschoben werden müssen und nicht, wie bei der vorliegenden Erfindung, nach vollendetem Verlegen angebracht werden können.■ new lines is more difficult because the hose pieces before being laid over the . Line must be pushed and not, as in the present invention, after after the installation has been completed.
In der Zeichnung zeigt Fig. 1 die Anwendung des Schutzstückes an einem um eine Mauerecke verlegten Knie; Fig. 2 zeigt die Anwendnng des Schutzstückes an einem in einem Mauerwinkel verlegten Knie und Fig. 3 zeigt den Querschnitt einer Ausführungsform des Schutzstückes.In the drawing, Fig. 1 shows the application of the protective piece to a a corner of the wall misplaced knees; Fig. 2 shows the application of the protective piece on a knee laid in a wall angle and FIG. 3 shows the cross section of an embodiment of the protective piece.
Mit α sind die Isolierröhren bezeichnet, an 4c deren Ecken und Biegungen Schutzstücke angeordnet werden, die aus gelenkig miteinander verbundenen Gliedern b zusammengesetzt sind. Diese Glieder haben entweder einen winkelförmigen oder einen U-förmigen Quer- 4: schnitt; es empfiehlt sich, Stücke mit ll-förmigem Querschnitt zu verwenden, bei welchen die Schenkel, wie aus Fig. 3 zu ersehen ist, einen dem Röhrendurchmesser entsprechenden Abstand haben. In diesem Falle können die Schutzstücke stramm über die verlegten Röhren gedrückt werden und sie halten sich dann ohne weitere Befestigung.With α the insulating tubes are designated, at 4c the corners and bends of which protective pieces are arranged, which are composed of articulated links b . These links have either an angular or a U-shaped cross section; it is advisable to use pieces with an ll-shaped cross-section in which the legs, as can be seen from FIG. 3, have a distance corresponding to the tube diameter. In this case, the protective pieces can be pressed tightly over the laid pipes and they then hold on without further fastening.
Die Schutzstücke werden aus Eisenblech oder sonstigem Material hergestellt, welches 5-gerade fest genug ist, um das Eintreiben von Nägeln zu verhindern.The protective pieces are made of sheet iron or other material that is 5-straight is strong enough to prevent nail driving.
