Description
Hakenhook
Die Erfindung bezieht sich auf einen Haken zum Befestigen von Lastketten, Seilen o. dgl. mit Sicherung gegen Herausfallen des eingehängten Teiles. Ihr Wesen besteht darin, daß im Haken in bekannter Weise ein mit Öffnung versehener, das einzuhängende Kettenglied o. dgl. aufnehmender, drehbarer Teil außermittig gelagert ist, derart, daß bei Lastwirkung die Öffnung des drehbaren Teiles ίο gegenüber der Hakenöffnung in einer um eine zwangsläufige Drehung verschobenen Lage gehalten ist.The invention relates to a hook for attaching load chains, ropes or the like with protection against falling out of the suspended part. Their essence is that in the hook in a known manner an opening provided, the chain link to be hung o. The like. Receiving, rotatable part is mounted eccentrically, such that when the load acts the opening of the rotatable part ίο opposite the hook opening in a an inevitable rotation shifted position is held.
Demgemäß erfolgt bei dem neuen Haken die Sicherung der Last gegen Herausfallen x, selbsttätig, und zwar durch den von ihr ausgeübten Zug.Accordingly, with the new hook, the load is secured against falling out x , automatically, by the pull it exerts.
Die Zeichnung gibt ein Ausführungsbeispiel der Erfindung wieder.The drawing shows an embodiment of the invention.
Abb. ι veranschaulicht einen Lasthaken in Offenstellung,Fig. Ι illustrates a load hook in the open position,
Abb. 2 den gleichen Haken in Sperrstellung, Fig. 2 the same hook in the locked position,
Abb. 3 einen Schnitt durch den Lasthaken nach der Geraden 6-6 der Abb. 2 und
2J5 Abb. 4 einen waagerechten Schnitt nach der
Geraden 7-7 der Abb. 2.Fig. 3 shows a section through the load hook along the line 6-6 in Fig. 2 and
2J 5 Fig. 4 a horizontal section along the straight line 7-7 in Fig. 2.
In dem Sicherheitshaken b gemäß den Abb. ι bis 4 ist das scheibenförmige Sperrglied« drehbar gelagert. Dieses Glied dient zur Aufnahme eines Kettengliedes oder Schellenzapfens c. Der Haken b ist in üblicher Weise mit einem Aufhängeauge b2 versehen, und der Querschnitt seiner Innenfläche entspricht einem Kreis mit dem Mittelpunkt*1, der zwischen der vertikalen Zentrallinie x2 und der Hakennase oder Hakenspitze bs liegt. Der Außenumfang des Gliedesa ist durch eine konkave Fläche gebildet, die sich über die Lagerfläche δ4 wölbt. Dank dieser Ausbildung kann sich das Glied ß in dem Haken ungehindert drehen, jedoch keine nennenswerte seitliche Verschiebung ausführen.The disk-shaped locking member is rotatably mounted in the safety hook b according to FIGS. This link is used to hold a chain link or clamp pin c. The hook b is provided in the usual way with a suspension eye b 2 , and the cross section of its inner surface corresponds to a circle with the center * 1 , which lies between the vertical central line x 2 and the hook nose or hook tip b s . The outer circumference of the limb is formed by a concave surface which arches over the bearing surface δ 4. Thanks to this training, the link ß can rotate freely in the hook, but not perform any significant lateral displacement.
Das den Backen a1 des Körpers α entsprechende Maul«2 ist von solcher Breite, daß, wenn der Schlitz oder die Öffnung b1 des Hakens in .die Deckungslage gebracht wird, ein Kettenglied c o. dgl. in die Backen eingeschoben werden kann, so daß es sich an ihrem inneren Ende befindet.The mouth « 2 corresponding to the jaws a 1 of the body α is of such a width that when the slot or the opening b 1 of the hook is brought into the covering position, a chain link c or the like can be inserted into the jaws, so that it is at its inner end.
Um zu erreichen, daß, nachdem der Teile in die Backe des Sperrgliedes eingeführt worden ist, durch dieses selbsttätig die Öffnung des Hakens geschlossen werde, sobald die Belastung stattfindet, ist die Backe des Gliedes α in bezug auf den Lagermittelpunkt x1 derart angeordnet, daß das innere Ende a3 der Backe exzentrisch zur Gelenklagerfläche δ4 liegt (Abb. i). Der Mittelpunkt*4 des Sitzes«3 In order to ensure that, after the part has been inserted into the jaw of the locking member, the opening of the hook will automatically be closed by this as soon as the load takes place, the jaw of the member α is arranged with respect to the bearing center x 1 such that the inner end a 3 of the jaw is eccentric to the joint bearing surface δ 4 (Fig. i). The center * 4 of the seat « 3
