Description

Sicherheitsgürtel mit Dämpfungsfeder. Gegenstand der Erfindung ist ein Sicherheitsgürtel, der insbesondere für die in Bergwerksschächten beschäftigten Grubenarbeiter bestimmt ist und sich von den bekannten Vorrichtungen dieser Art dadurch unterscheidet, daß zur Stoßdämpfung beim Fall des Arbeiters eine Feder zwischen die beiden Enden einer am Seil vorgesehenen Schleife eingeschaltet ist, die an zwei an den Schleifenenden angebrachten Knoten angreift.Safety belt with damping spring. The subject of the invention is a safety belt, especially for those employed in mine shafts Mine workers is intended and differs from the known devices of this type differs in that for shock absorption when the worker falls, a spring between the two ends of a loop provided on the rope is switched on, which is connected to two Attacks knot attached to the loop ends.

Abb. i zeigt den ganzen Gürtel mit Halteseil, Abb. a die Verbindung des Halteseils mit dem Gürtel. _ An den z. B. aus Hanf hergestellten ganz geschlossenen Gürtel a sind an der Vorderseite zwei Riemen b1, b2, die in Schnallen cl, c2 eingesteckt werden können, zum Anpassen des Gürtels an den Leib des Arbeiters angebracht. Beim Zusammenschnallen des Gürtels faltet sich der zwischen den Riemen und den Schnallen liegende Gürtelteil d, wie Abb. i zeigt. Vom Gürtel gehen zwei Tragbänder e1, e2 aus, die über die Schultern des Arbeiters verlaufen und gekreuzt sind. Die Schnallen f1, f2 dienen zur Einstellung der Tragbänder, die an der Vorderseite des Gürtels mittels der Karabinerhaken g1, g2 befestigt sind.Fig. I shows the entire belt with the tether, Fig. A the connection the tether with the belt. _ At the z. B. made of hemp completely closed Belt a are two straps b1, b2, which are inserted into buckles cl, c2 on the front can be attached to adjust the belt to the body of the worker. At the Buckling up the belt folds between the straps and the buckles lying belt part d, as Fig. i shows. Two carrying straps e1, e2 go from the belt that pass over the worker's shoulders and are crossed. The buckles f1, f2 are used to adjust the straps attached to the front of the belt are attached by means of the snap hooks g1, g2.

Das Halteseil h ist am Gürtel in folgender Weise befestigt: Der-Gürtel ist an der Rückseite zwei- oder mehrfach zusammengefaltet, um an dieser Stelle eine größere Starrheit zu erhalten (Abb. a, d, a2). Dieser zusammengefaltete Gürtelteil wird von dem freien Ende hl des Seiles h umschlungen, und dieses freie Seilende hl wird mit dem anderen Seilteil h durch Verspleißen bei h$ (vgl. Abb. z) verbunden. Ferner werden zu beiden Seiten des den Gürtel umschließenden Seilteiles zwei Platten j1, j2, z. B. aus Leder, angebracht und mit dem Gürtel verbunden. Auf diese Weise wird eine sehr feste und zuverlässige Verbindung von Seil und Gürtel erreicht.The tether h is attached to the belt in the following way: The belt is folded two or more times on the back in order to obtain greater rigidity at this point (Fig. A, d, a2). This folded belt part is wrapped around by the free end hl of the rope h, and this free rope end hl is connected to the other rope part h by splicing at h $ (see Fig. Z). Furthermore, two plates j1, j2, z. B. made of leather, attached and connected to the belt. In this way, a very firm and reliable connection between rope and belt is achieved.

Am oberen. Ende des Seiles ist eine Schleife k gebildet, an deren Enden zwei Knoten hl, k2 angebracht sind, zwischen die eine Feder L eingefügt ist, wie Abb. i erkennen läßt. Iin Falle eines Sturzes des Arbeiters wird der auftretende Stoß durch die Feder L gedämpft. Wird die Feder 1 vollständig gespannt oder bricht sie, so wird das Seilstück der Schleife k aufgenommen, so daß ein Unfall nicht möglich ist.At the top. At the end of the rope a loop k is formed, at which Ends two nodes hl, k2 are attached, between which a spring L is inserted, as Fig. i shows. In the event of a fall of the worker, the occurring Shock is dampened by the spring L. If the spring 1 is fully tensioned or breaks they, so the piece of rope of the loop k is added, so that an accident is not possible is.

Der neue Sicherheitsgürtel kann nicht nur bei Grubenarbeiten, sondern auch sonst überall da Verwendung finden, wo es sich darum handelt, einen Arbeiter bei einer mit Absturzgefahr verbundenen Beschäftigung zuverlässig zu halten.The new safety belt can not only be used during mine work, but can also be used everywhere else where it is a matter of a worker to be held reliably in an occupation associated with the risk of falling.
