Description
Aus zwei spiegelbildlich zueinander gestellten S-förmigen Teilen, die um einen in der Mitte angeordneten Bolzen drehbar sind, bestehender Doppelhaken für Ketten o. dgl., die durch ein zwischen den Teilen einstellbares Verschlußglied gesichert werden, ist bekannt. Das Neue besteht darin, daß das Verschlußglied aus einem um den Bolzen schwenkbaren Blech von demselben Umriß der Teile des Doppelhakens besteht, dessen die eingehängten Kettenglieder aufnehmende Ausnehmungen im gleichen Drehsinne nach dem Rande offen sind und das in der Verschlußstellung durch eine an einer Ausnehmung vorgesehene Ausbördelung und durch einen Vorsprung an seinem Rande beide Hakenteile gegen Drehen sichert.From two mirror-inverted S-shaped parts, which are arranged around one in the Pins arranged in the center are rotatable, existing double hooks for chains o be secured by a locking member adjustable between the parts is known. The novelty is that the closure member consists of a pivotable about the bolt Sheet consists of the same outline of the parts of the double hook of which the hooked Chain links receiving recesses are open in the same direction of rotation after the edge and that in the closed position by a flange provided on a recess and by a projection its edge secures both parts of the hook against turning.
Die in den Haken eingehängten Ketten sind durch diese einfache und billige AusbildungThe chains hooked into the hook are simple and cheap because of this training
ao in allen praktisch vorkommenden Fällen gegen Herausfallen gesichert.ao secured against falling out in all practical cases.
Auf der Zeichnung ist der Haken in der geschlossenen und offenen Stellung sowie auch in seinen Einzelteilen dargestellt.On the drawing the hook is in the closed and open positions as well shown in its individual parts.
«5 In die Ketten oder Seile, welche zusammengeschlossen werden sollen, werden zu gleicher Zeit bei geöffnetem Haken Enden e eines Teiles eingelegt und verweilen so lange, bis der zweite Teil / durch Drehen um den Bolzen ebenfalls das Einhängen der Kette ermöglicht. Jetzt wird das Verschlußglied α in die Sicherungslage gedreht, so daß die Ausnehmungen c und c' des Verschiußgliedes α die Kettenglieder übergreifen. Hierbei springt die Ausbördelung g in die eine Hakenöffnung ein, und der Vorsprung b lehnt sich gegen den anderen Hakenteil. Hiernach kann ein selbsttätiges öffnen des Sicherheitshakens bei belasteten und unbelasteten Ketten oder Seilen nicht mehr eintreten. Das öffnen erfolgt durch Angreifen des Verschiußgliedes α an dem Vorsprung b und durch Drehen des Verschlußgliedes α, wobei die Ausbördelung g aus der Hakenöffnung herausspringt.«5 At the same time, with the hook open, ends e of a part are inserted into the chains or ropes that are to be joined and remain there until the second part / by turning around the bolt also enables the chain to be attached. The locking member α is now rotated into the securing position so that the recesses c and c 'of the locking member α overlap the chain links. Here, the flanging g jumps into the one hook opening, and the projection b leans against the other hook part. After this, the safety hook can no longer open automatically with loaded and unloaded chains or ropes. The opening takes place by engaging the closure member α on the projection b and by rotating the closure member α, the flanging g jumping out of the hook opening.
