Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Stab für Schutzgitter zur Sicherung von Fenstern und Türen gegen Einbruch. Das zur Herstellung solcher Gitter allgemein verwendete Rund- oder Vierkanteisen kann ohne auffälliges Geräusch zersägt werden. Zweck der Erfindung ist, diesen Übelstand zu beseitigen.The invention relates to a rod for protective grating for securing windows and doors against burglary. The round or square iron generally used to manufacture such grids can be sawed without a noticeable noise. The purpose of the invention is to remedy this drawback.

Fig. ι stellt einen Längsschnitt und Fig. 2 einen Querschnitt durch einen Gitterstab dar.Fig. 1 shows a longitudinal section and Fig. 2 shows a cross section through a lattice bar.

Der Stab besteht aus einem nahtlos gezogenen Rohr aus Stahl oder Eisen, aus dem das Gitter so hergestellt wird, daß bei Verwendung von Längs- und Quersprossen die Kreuzungstellen miteinander verschweißt werden. In das Rohr« wird ein Eisenstab δ eingezogen, dessen Durchmesser etwa ein Drittel des Rohrdurchmessers beträgt. In den zwischen der Innenwand des Rohres α und dem Eisenstab b entstehenden Raum wird ein zusammengerollter Zylinder c aus Drahtgeflecht eingeschoben und der Zwischenraum sodann mit flüssigem Glas ausgegossen, so daß dieses nach dem Erkalten das Glasrohr d bildet, in welches der Drahtzylinder c fest eingegossen ist.The rod consists of a seamlessly drawn tube made of steel or iron, from which the grid is made in such a way that the crossing points are welded together when using longitudinal and transverse rungs. An iron rod δ, the diameter of which is about a third of the pipe diameter, is drawn into the pipe. A rolled-up cylinder c made of wire mesh is inserted into the space created between the inner wall of the tube α and the iron rod b and the space is then filled with liquid glass, so that after cooling it forms the glass tube d into which the wire cylinder c is firmly cast .

Wenn nun bei einem Einbruch das Außenrohr α durchschnitten wird, so wird das Glasrohr d den gebräuchlichen Schneidwerkzeugen infolge seiner Härte widerstehen. Es wäre deshalb nötig, ein größeres Stück desselben freizulegen, um es dann zu zertrümmern, was mit einem starken Geräusch verbunden wäre, zumal ja die Zerstörung infolge des eingegossenen Drahtzylinders c wesentlich erschwert und aus diesem Grunde auch das Zerschneiden das Glasrohres Schwierigkeiten machen würde.If the outer tube α is cut through in the event of a break-in, the glass tube d will withstand the usual cutting tools due to its hardness. It would therefore be necessary to expose a larger piece of the same in order to then smash it, which would be associated with a loud noise, especially since the destruction due to the cast wire cylinder c is made much more difficult and for this reason cutting the glass tube would also make it difficult.

Claims (1)

Patent-Anspruch:Patent claim: Gitterstab für Schutzgitter gegen Einbruch, dadurch gekennzeichnet, daß der Stab aus nahtlos gezogenem Eisenrohr (a) und einem den Höhlraum des Rohres (a)-nicht ausfüllenden Eisenstab (b) besteht, wobei der zwischen beiden entstehende Raum mit Glas ausgegossen ist, das durch einen eingeschobenen Zylinder aus Drahtgeflecht verstärkt wird.Grating bar for protective grating against burglary, characterized in that the bar consists of seamlessly drawn iron tube (a) and an iron bar (b) which does not fill the cavity of the tube (a) , the space between the two being filled with glass that passes through an inserted cylinder made of wire mesh is reinforced.
