Da der Winkelhebel mit seinem freien Ende von außen in die Öffnung der Aufnahme ragt, begrenzt er den Grad der Schwenkbarkeit des Hakens.From the DE 198 56 177 A1 a hook of the type considered is known, the fuse consists of a pivotally mounted on the hook angle lever, which after the insertion of two hammer head forming a hook nose into the receptacle of the container preferably under the action of a spring force with its free end in the opening of the receptacle engages after it has been previously held by the person handling the hook in an inactive position, in which he must be swung back when removing the hook from its receptacle. Since the angle lever protrudes with its free end from the outside into the opening of the receptacle, it limits the degree of pivoting of the hook.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen Haken der in Betracht gezogenen Art so auszugestalten, dass er sich bequem mit einer Hand handhaben lässt. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sicherung aus einem in einer im Bereich des in die Hakennase übergehenden Endes des Schwenkzapfens angeordneten ersten Bohrung des Hakens geführten Sperrbolzen und einem in einer die erste Bohrung schneidenden, durch den Schwenkzapfen verlaufenden zweiten Bohrung des Hakens geführten Betätigungsbolzen sowie einer den Sperrbolzen in die Sperrstellung drückenden Feder besteht, wobei der Sperrbolzen eine Ausnehmung mit einer Schrägfläche aufweist, über die durch einen in der Ausnehmung geführten Abschnitt des Betätigungsbolzens eine der Federkraft entgegengerichtete, den Sperrbolzen aus seiner Sperrposition entfernende Bewegung in den Sperrbolzen einleitbar ist.The invention has for its object to design a hook of the type considered so that it can be handled easily with one hand. This object is achieved in that the backup of a in the region of the hook nose in the transition end of the pivot pin arranged first bore of the hook guided locking pin and a in a first bore intersecting, passing through the pivot second Bore of the hook guided actuating pin and a locking pin in the locking position oppressive spring, wherein the locking pin has a recess with an inclined surface on the guided through a guided in the recess portion of the actuating bolt one of the spring force opposing, the locking pin from its locking position removing movement in the locking pin can be introduced.

Der erfindungsgemäße Haken bietet den Vorteil, dass der Sperrbolzen beim Einführen der Hakennase in die Aufnahme des Containers problemlos in seine Sicherungsposition überführbar ist und beim Lösen des Hakens auch lediglich ein Druck auf das freie Ende des Betätigungsbolzens ausgeübt werden muss. Da der Sperrbolzen die Einführöffnung hintergreift, sind Drehbewegungen des Hakens um 180° ohne die Gefahr einer Beschädigung der Sicherung möglich.The hook according to the invention has the advantage that the locking pin during insertion of the hook nose into the receptacle of the container can be easily converted into its secure position and when releasing the hook and only a pressure on the free end of the actuating bolt must be exercised. Since the locking pin engages behind the insertion opening, rotational movements of the hook are possible by 180 ° without the risk of damaging the fuse.

Wege zur Ausführung der ErfindungWays to carry out the invention

In den Figuren ist 1 der von einem Benutzer in die Hand nehmbare Hauptteil eines Hakens, der mit einem einen Anschlussbolzen 2 aufweisenden Gabelkopf 3 für eine nicht dargestellte Anschlagkette oder ein Hubseil versehen ist. An den Hauptteil 1 des Hakens schließt sich ein Schwenkzapfen 4 an, der an seinem freien Ende in eine Hakennase 5 übergeht. Anstelle der dargestellten einen Hakennase 5 können auch zwei hammerkopfartig angeordnete Hakennasen Verwendung finden.In the figures, 1 is the main part of a hook which can be picked up by a user and which is provided with a clevis 3 having a connection pin 2 for a stop chain or hoist chain (not shown). The main part 1 of the hook is followed by a pivot pin 4, which merges at its free end into a hook nose 5. Instead of the one hooked nose 5 shown, two hook-head-like hooked noses can also be used.

Durch den Hauptteil 1 und den Schwenkzapfen 4 des Hakens verläuft eine sich bis in den Bereich der Hakennase 5 erstreckende Bohrung 6, deren Längsachse 7 senkrecht zur Längsachse 8 einer weiteren Bohrung 9 steht und die sich fast über die gesamte Breite b des Schwenkzapfens 4 bzw. der Hakennase 5 erstreckt.Through the main part 1 and the pivot pin 4 of the hook extending up to the area of the hook nose 5 extending bore 6, the longitudinal axis 7 is perpendicular to the longitudinal axis 8 of a further bore 9 and almost over the entire width b of the pivot pin 4 and the hook nose 5 extends.

In der Bohrung 6 ist ein Betätigungsbolzen 10 gelagert, mit dessen Hilfe ein in der Bohrung 9 geführter Sperrbolzen 11 gegen die Wirkung einer Feder 12 aus einer in den Figuren 2, 3 und 8 dargestellten Sperrposition in die in Fig. 9 gezeigte Freigabeposition drückbar ist.In the bore 6, an actuating pin 10 is mounted, with the help of a guided in the bore 9 locking pin 11 against the action of a spring 12 from a in the FIGS. 2, 3 and 8th Lock position shown in the in Fig. 9 shown release position is pressed.

Wie insbesondere den Figuren 6 und 7 entnommen werden kann, besitzt der Betätigungsbolzen 10 an seinem freien Ende eine Schrägfläche 13, an die sich ein Rastnocken 14 anschließt, der im montierten Zustand des Betätigungsbolzens 10 den Sperrbolzen 11 hintergreift und auf diese Weise den Zusammenhalt von Betätigungsbolzen 10 und Sperrbolzen 11 gewährleistet. Eine senkrecht zur Längsachse 7 des Betätigungsbolzens 10 verlaufende Anschlagfläche 15 begrenzt den Hub des Betätigungsbolzen 10.As in particular the FIGS. 6 and 7 can be removed, the actuating pin 10 has at its free end an inclined surface 13 to which a locking cam 14 connects, which engages behind the locking pin 11 in the mounted state of the actuating bolt 10 and in this way ensures the cohesion of actuating pin 10 and locking pin 11. A perpendicular to the longitudinal axis 7 of the actuating bolt 10 extending stop surface 15 limits the stroke of the actuating bolt 10th

Das den Rastnocken 14 aufweisende Ende des Betätigungsbolzens 10 greift in eine Ausnehmung 16 des Sperrbolzens 11, die eine zum Zusammenspiel mit der Schrägfläche 13 des Betätigungsbolzens 10 bestimmte Schrägfläche 17 aufweist.The locking cam 14 having the end of the actuating bolt 10 engages in a recess 16 of the locking bolt 11, which has a certain interaction with the inclined surface 13 of the actuating bolt 10 inclined surface 17.

Die Schrägfläche 17 des Sperrbolzens 11 nimmt zur Längsachse 8 des Sperrbolzens 11 einen Winkel α von ca. 50° ein, während der Winkel β zwischen der Schrägfläche 13 des Betätigungsbolzens 10 und dessen Längsachse 7 ca. 40° beträgt. An seinem in der Sperrstellung über den Umfang des Schwenkzapfens 4 vorstehenden Ende ist der Sperrbolzen 11 mit einer weiteren Schrägfläche 18 ausgestattet, die gegenüber der Längsachse 8 des Sperrbolzens 11 einen Winkel γ von etwa 60° einnimmt.The inclined surface 17 of the locking pin 11 takes the longitudinal axis 8 of the locking bolt 11 an angle α of about 50 °, while the angle β between the inclined surface 13 of the actuating bolt 10 and the longitudinal axis 7 is about 40 °. At its in the blocking position over the circumference of the pivot pin 4 projecting end of the locking pin 11 is provided with a further inclined surface 18 which assumes an angle γ of about 60 ° relative to the longitudinal axis 8 of the locking pin 11.

Dank der Schrägfläche 18 und der Art der Zuordnung des Betätigungsbolzens 10 zum Sperrbolzen 11 wird letzterer beim Einführen der Hakennase 5 in eine der Form der Hakennase 5 angepasste Öffnung 19 eines am Container angeordneten Beschlages 20 durch eine der Längskanten 21 bzw. 22 der Öffnung 19 automatisch in die in Figur 9 dargestellte Position überführt. Sobald der Sperrbolzen 11 die Vorderwand 23 des Beschlages 20 passiert hat, wird das Ende des Sperrbolzens 11 durch die Feder 12 in die in Fig. 8 dargestellte Position zurückbewegt, so dass die Hakennase 5 sicher im Beschlag 20 gehalten wird.Thanks to the inclined surface 18 and the nature of the assignment of the actuating bolt 10 to the locking pin 11 is the latter when inserting the hook nose 5 in one of the shape of the hook nose 5 adapted opening 19 of a container arranged on the fitting 20 by one of the longitudinal edges 21 and 22 of the opening 19 automatically in the in FIG. 9 transferred position shown. Once the locking pin 11 has passed the front wall 23 of the fitting 20, the end of the locking pin 11 by the spring 12 in the in Fig. 8 shown moved back position so that the hook nose 5 is securely held in the fitting 20.

Um die Teile 10, 11 und 12 der Sicherung einfach montieren und demontieren zu können, ist der Sperrbolzen 11 mit einer Einführnut 24 versehen, die der Rastnocken 14 passieren kann, wenn der Sperrbolzen 11 beispielsweise unter Zuhilfenahme eines Bleistiftes oder Dornes mit einer Kraft P in Richtung des Pfeiles 25 gegen die Wirkung der Feder 12 in die in Figur 10 dargestellte Position gedrückt wird. Um den Aufbau eines Luftpolsters im Bereich der Feder 12 zu verhindern, schließt sich an das Ende der Bohrung 9 eine Entlüftungsbohrung 26 an.In order to easily assemble and disassemble the parts 10, 11 and 12 of the fuse, the locking pin 11 is provided with a Einführnut 24 which can pass the locking cam 14 when the locking pin 11, for example, with the aid of a pencil or mandrel with a force P in Direction of the arrow 25 against the action of the spring 12 in the in FIG. 10 shown position is pressed. In order to prevent the buildup of an air cushion in the region of the spring 12, a vent hole 26 adjoins the end of the bore 9.

Wie insbesondere der Fig. 11 entnehmbar ist, kann die Längsachse 27 der Hakennase 5 Schräglagen einnehmen, die bei der eingangs beschriebenen bekannten Konstruktion nicht realisierbar sind.How the particular Fig. 11 can be removed, the longitudinal axis 27 of the hook nose can assume 5 inclined positions, which are not feasible in the known construction described above.
