Mit einem beweglichen Anhängemittel, zum Beispiel Öse versehene Lastanschlagvorrichtung"Load attachment device provided with a movable attachment, for example an eyelet "
Die Erfindung betrifft eine mit einem beweglichen Anhängemittel, zum Beispiel Öse versehene Lastanschlagvorrichtung mit einem verschiebbaren Haltebolzen zur Aufnahme der Last, wobei quer zu der Verschiebehubrichtung des Haltebolzens ein unter Federdruck stehender verschiebbarer Riegel angeordnet ist.The invention relates to a load attachment device provided with a movable attachment means, for example an eyelet with a displaceable retaining bolt for receiving the load, being transverse to the displacement stroke direction of the retaining bolt a sliding bolt under spring pressure is arranged.
Lastanschlagvorrichtungen dienen bekanntlich dazu, mit Hilfe des verschiebbaren Haltebolzens eine Last anzuhängen. Hat der Haltebolzen die Last erfaßt, dann sorgt der unter Federdruck stehende Riegel dafür, daß der Haltebolzen seine Ausgangslage nicht wieder einnehmen kann. Erst wenn der Riegel zurückgezogen wird, wird der Haltebolzen freigegeben, so daß damit auch die Last freigegeben wird. Da der Riegel mit Hilfe eines Zugseiles fernbedient wird, besteht die Gefahr, daß das Zugseil unbeabsichtigt betätigtAs is known, load attachment devices are used to attach a load with the aid of the displaceable retaining bolt. If the retaining bolt has captured the load, the spring-loaded bolt ensures that the retaining bolt is its Can not take the starting position again. Only when the bolt is withdrawn, the retaining bolt is released, see above that this also releases the load. Since the bolt is operated remotely with the help of a pull rope, there is the risk that the pull rope is accidentally actuated

wird, beispielsweise dann, wenn sich das Zugseil irgendwie verhakt. In diesem Falle würde die Last unbeabsichtigt freigegeben werden.is, for example, if the pull rope gets caught somehow. In this case the load would be released unintentionally will.
Der Erfindung liegt die Aufgabe zugrunde, eine Lastanschlagvorriehtung zu schaffen, bei der ein unbeabsichtiges Lösen der Last vermieden ist.The invention is based on the object of a load stop device to create in which an unintentional release of the load is avoided.
Nach der Erfindung wird das dadurch erreicht, daß quer zu der Verschiebehubrichtung des Haltebclzens eine verschiebbare und unter Federdruck stehende Sicherheitssperre eingeschaltet ist, deren Verschiebeweg von dem beweglichen Anhängemittel gesteuert ist.According to the invention, this is achieved in that transversely to the displacement stroke direction of the retaining clip a slidable and spring-loaded safety lock is switched on, the displacement of which is from the movable attachment means is controlled.
Die Ausbildung ist dabei so getroffen, daß ein Schwenkhebel vorgesehen ist, dessen eines Ende auf die Sicherheitssperre einwirkt und dessen anderes Ende mit dem beweglichen Anhängemittel in Verbindung steht. Zur Verbindung dieses anderen Endes des Schwenkhebels dient dabei vorzugsweise eine Feder.The training is made so that a pivot lever is provided, one end of which on the safety lock acts and the other end is connected to the movable hitch. To connect this other A spring is preferably used at the end of the pivot lever.
Ist die Last angehoben, dann wird durch das dabei eintretende Verschwenken des beweglichen Anhängemittels eine Zugkraft auf den Schwenkhebel ausgeübt, wodurch der Schwenkhebel verstellt wird. Dadurch wird auch die Sicherheitssperre in die Verriegelungsstellung verschoben, so daß der Haltebolzen verriegelt ist, und zwar auch dann, wenn der Hiegel unbeabsichtigt gelöst werden sollte.If the load is raised, then a tensile force is generated by the pivoting of the movable attachment means that occurs in the process exercised the pivot lever, whereby the pivot lever is adjusted. This also moves the safety lock into the locked position moved so that the retaining bolt is locked, even if the latch is unintentionally released should be.
Ist die Last abgesenkt, dann ist das zwischen dem Schwenkhebel und dem Anhängemittel eingeschaltete Verbindungsmittel, zum Beispiel die Feder, wirkungslos, so daß die Sicherheitssperre unter der Wirkung ihrer Feder in die Entriegelungsstellung gelangen kann. Der Riegel wird dann zurückgezogen, so daßIf the load is lowered, then the connecting means switched on between the pivot lever and the attachment means is for the Example the spring, ineffective, so that the safety lock under the action of its spring in the unlocked position can get. The latch is then withdrawn so that

sich der Haltebolzen unter dem Drucke seiner Feder in die Ausgangslage verschiebt. Die Lastanschlagvorrichtung gibt dann die Last frei.the retaining bolt moves into the starting position under the pressure of its spring. The load attachment device gives then free the load.
In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.An example embodiment is shown in the drawing.
Fig. 1 zeigt die Lastanschlagvorrichtung mit eingehängter Last und belasteter Anhängöse;1 shows the load attachment device with a suspended load and a loaded suspension eye;
Fig. 2 zeigt die Lastanschiagvorrichtung mit entlasteter Anhängöse;Fig. 2 shows the load abutment device with relieved Attachment loop;
Fig. 3 zeigt die Lastanschlagvorrichtung in der Entriegelungssteilung.Fig. 3 shows the load attachment device in the unlocking division.
Die insgesamt mit 17 bezeichnete Lastanschlagvorrichtung besteht aus dem Gehäuse 1, welches das geschwungene Haisstück: 1a besitzt; in dem Gehäuse 1 ist der Haiteboizen 2 für die Last 9 verschiebbar gelagert; wobei das Ende des Haltebolzens 2 in ein Endlager 18 im Haisstück Ia eingreifen kann. Der Haltebolzen 2 besitzt den Bund 4, an dem sich die Feder 6 abstützt. Das andere Ende der Feder 6 stützt sich bei 3 ab.The load attachment device, designated as a whole by 17, consists of the housing 1, which has the curved neck piece: 1a; The Haiteboizen 2 is in the housing 1 mounted displaceably for the load 9; the end of the retaining bolt 2 engaging in an end bearing 18 in the shank piece Ia can. The retaining bolt 2 has the collar 4 on which the spring 6 is supported. The other end of the spring 6 is supported at 3.
Quer zu der Verschiebehubrichtung des Kalteboisens 2 ist der Riegel in Form eines verschiebbaren Stiftes 5 angeordnet. Dieser Stift 5 steht unter dem Drucke der Feder 7; er besitzt das Zugmittel 8.Transverse to the displacement stroke direction of the cold boring 2 is the bolt is arranged in the form of a displaceable pin 5. This pin 5 is under the pressure of the spring 7; he has the traction device 8.
Weiterhin ist quer zu der ferschiebehubrichtung des Haltebolzens 2 eine Sieherheitssperre in Form eines verschiebbaren Sicherheitsstiftes 10 vorgesehen, der ebenfalls unter dem Drucke einer Feder 11 steht.Furthermore, it is transverse to the sliding stroke direction of the retaining bolt 2 a security lock in the form of a sliding safety pin 10 is provided, which is also under the pressure of a spring 11 stands.

Die Verriegelungsstellung nimmt der Sicherheitsstift 10 mit Hilfe des Schwenkhebels 12 ein, der um die Achse 13 verschwenkbar ist. Das andere Ende des Schwenkhebels 12 steht mit dem Anhängemittel 15 durch eine Feder 14 in Verbindung. Die von der Feder 14 ausgeübte Kraft ist größer als die Kraft der Feder 11. Dadurch ist erreicht, daß bei belasteter Anhängöse der Schwenkhebel 12 den Sicherheitsstift 10 in die Verriegelungsstellung bringt.The locking position is assumed by the safety pin 10 with the aid of the pivot lever 12, which can pivot about the axis 13 is. The other end of the pivot lever 12 is connected to the attachment means 15 by a spring 14. The force exerted by the spring 14 is greater than the force of the spring 11. This ensures that when loaded The attachment eye of the pivot lever 12 brings the safety pin 10 into the locking position.
Fig. 2 zeigt die Lastanschlagvorrichtung mit entlastetem Anhängemittel 15. Bei entlastetem Anhängemittel 15 ist die Feder 14 entspannt, so daß unter dem Drucke der Feder 11 der Sicherheitsstift 10 den Schwenkhebel 12 verschwenken kann, so daß der Sicherheitsstift 10 aus seiner Verriegelungsstellung gelangt.Fig. 2 shows the load attachment device with relieved attachment means 15. When the attachment means 15 is relieved, the The spring 14 is relaxed so that the safety pin 10 swivels the pivot lever 12 under the pressure of the spring 11 can, so that the safety pin 10 comes out of its locking position.
Zum Zwecke der vollständigen Lastfreigabe wird an dem Zugseil 8 gezogen, so daß der Stift 5 in die Entriegelungslage gelangt. Dadurch ist der Haltebolzen 2 völlig freigegeben, wie das in der Fig. 3 im einzelnen nochmals dargestellt ist.For the purpose of complete load release, pulling rope 8 is pulled so that pin 5 is in the unlocked position got. As a result, the retaining bolt 2 is completely released, as shown again in detail in FIG. 3 is.
Bei der dargestellten Ausführungsform wird die Beweglichkeit des Anhängemittels dadurch erzielt, daß das Anhängemittel schwenkbar ist. Die gleiche Wirkung kann auch durch ein längsverschiebliches Anhängemittel, zum Beispiel Anhängeöse, erzielt werden, wobei die Anhängeöse auf einer vertikalen Achse längsverstellt werden kann.In the illustrated embodiment, the mobility of the attachment means is achieved in that the attachment means is pivotable. The same effect can also be achieved with a longitudinally movable attachment device, for example a suspension eye, can be achieved, whereby the lanyard can be adjusted lengthways on a vertical axis.
