Description

Die Erfindung bezieht sich auf einen Verschluss, Drehriegelspannverschluss gemäss dem Oberbegriff des Anspruchs 1, für ein bewegliches Aufbauteil von Lastfahrzeugen, Containern und dergleichen, mit einem auf einem Träger drehbar gelagerten und hinter ein Gegenelement eines festen Aufbauteils eindrehbaren zweiarmigen Drehriegel, der einen Schliessarm und einen Kurbelarm aufweist und der durch einen am Träger angelenkten Handhebel über ein einerseits am Kurbelarm und andererseits am Handhebel angelenktes Verbindungsglied drehbar ist, wobei die Drehachse des Drehriegels parallel zur Oberfläche des beweglichen Aufbauteils verläuft und wobei der Handhebel in Schliessstellung durch eine Übertotpunktlage der Anlenkpunkte niedergehalten wird.The invention relates to a lock, turnbuckle fastener according to the preamble of claim 1, for a movable body part of trucks, containers and the like, with a rotatably mounted on a carrier and behind a counter element of a fixed body part, a locking arm and a locking arm Has crank arm and which can be rotated by a hand lever articulated on the carrier via a connecting link articulated on the crank arm and on the other hand on the hand lever, the axis of rotation of the rotary bolt running parallel to the surface of the movable mounting part and the hand lever being held down in the closed position by an over-center position of the articulation points.

Bei Verschlüssen für ein bewegliches Aufbauteil von Lastfahrzeugen, Containern und dergleichen, beispielsweise für Bordwände von Lastfahrzeugen, spielt das sogenannte «Heranholvermögen» eine besondere Rolle. Die Aufbauten von Lastfahrzeugen und ähnlichen Transporteinrichtungen unterliegen meistens einer rauhen Behandlung, was dazu führt, dass sie oft verbogen oder anderweitig verformt sind. Die bekannten Hakenspannverschlüsse, von denen beispielsweise einer aus der DE-C-1 678155 bekannt ist, haben bei Bordwänden von Lastfahrzeugen vielfach Verwendung gefunden, da sie ein verhältnismässig gutes Heranholvermögen in der Ebene der Bordwand aufweisen, so dass eine verbogene Bordwand, die mit einem solchen Verschluss ausgerüstet ist, ohne grössere Mühe geschlossen werden kann. Wenn jedoch eine Bordwand eines Lastfahrzeugs oder eine Türe eines Containers gegen den Innendruck des Ladeguts geschlossen werden soll, dann sind solche Hakenspannverschlüsse weniger geeignet, da sie ein Heranholen der Bordwand senkrecht zu ihrer Ebene kaum ermöglichen.In the case of closures for a moving body part of trucks, containers and the like, for example for side walls of trucks, the so-called "recovery capacity" plays a special role. The structures of trucks and similar transport devices are usually subjected to a rough treatment, which means that they are often bent or otherwise deformed. The known hook-and-loop fasteners, one of which is known, for example, from DE-C-1 678155, have found widespread use in the side walls of trucks, since they have a relatively good pull-in capability in the plane of the side wall, so that a bent side wall which is connected to a such closure is equipped, can be closed without much effort. However, if a side wall of a truck or a door of a container is to be closed against the internal pressure of the cargo, then such hook-and-loop fasteners are less suitable because they hardly allow the side wall to be brought up perpendicular to its plane.

Man ist deshalb zu Drehriegelverschlüssen übergegangen, von denen beispielsweise einer im DE-U-8003816 beschrieben ist. Der Drehriegel dreht sich beim Schliessvorgang hinter ein an einem festen Aufbauteil befestigtes Gegenelement und holt dabei die Bordwand in einer Richtung senkrecht zur Bordwandebene heran. Nachteilig an diesem Verschluss ist, dass mit ihm das bewegliche Aufbauteil, wie z.B. die Bordwand, nicht gegen das freie Aufbauteil verspannt werden kann.One has therefore switched to rotary bolt closures, one of which is described, for example, in DE-U-8003816. During the closing process, the rotary latch turns behind a counter element fastened to a fixed structural part and brings the drop side in a direction perpendicular to the drop side plane. The disadvantage of this closure is that it can be used to move the moving body part, e.g. the side wall, can not be braced against the free body.

Ein gutes Heranholvermögen in einer Richtung senkrecht zur Bordwand und eine Verspannung der Bordwand gegenüber dem benachbarten festen Aufbauteil des Lastfahrzeugs gestatten sogenannte Drehstangenverschlüsse, wie sie beispielsweise aus der DE-A-1430099, der DE-A-2847744 und dem DE-U-1 985489 bekannt sind. Bei einem Drehstangenverschluss ist der Drehriegel hakenförmig ausgebildet und an dem über die obere Kante der Bordwand hinausragenden Ende einer vertikal verlaufenden Drehstange befestigt, die mit Hilfe eines weiter unten an der Drehstange angreifenden Handhebels betätigbar ist. Der hakenförmige Drehriegel hintergreift ein auf dem oberen Ende des festen Aufbauteils angeordnetes Gegenelement, wie z.B. einen Zapfen. Drehstangenverschlüsse werden nur in Spezialfällen eingesetzt, beispielsweise bei besonders hohen Bordwänden, da sie verhältnismässig aufwendig sind, und zwar insbesondere hinsichtlich ihrer Mechanik. Ausserdem gestatten sie zwar ein Verspannen der Bordwand am festen Aufbauteil, ihr Heranholvermögen in der Ebene der Bordwand ist jedoch verhältnismässig begrenzt.A good pull-up ability in a direction perpendicular to the side wall and a tensioning of the side wall with respect to the adjacent fixed body part of the truck allow so-called espagnolette locks, such as those from DE-A-1430099, DE-A-2847744 and DE-U-1 985489 are known. In the case of a espagnolette lock, the rotary latch is hook-shaped and is fastened to the end of a vertically extending revolving rod which projects beyond the upper edge of the side wall and which can be actuated with the aid of a hand lever acting further down on the revolving rod. The hook-shaped rotary latch engages behind a counter element, such as a pin, arranged on the upper end of the fixed structural part. Espagnolette locks are only used in special cases, for example with particularly high drop sides, since they are relatively complex, in particular with regard to their mechanics. They also allow Although a brace the ship's side to the fixed body part, their Heranholvermögen in the plane of the hull, however verhältnismässi g limited.

Der Erfindung lag die Aufgabe zugrunde, einen aus dem DE-U-8003816 bekannten Drehriegelspannverschluss der eingangs näher beschriebenen Art so weiterzubilden, dass er nicht nur ein vorzügliches Heranholvermögen senkrecht zur Ebene des festen Aufbauteils, beispielsweise einer Bordwand, sondern auch in der Ebene desselben besitzt und in der Lage ist, das feste Aufbauteil mit dem beweglichen zu verspannen.The invention was based on the object of developing a rotary latch tensioning closure known from DE-U-8003816 of the type described in the introduction in such a way that it not only has an excellent pull-up ability perpendicular to the plane of the fixed structural part, for example a side wall, but also in the plane thereof and is able to clamp the fixed body with the movable one.

Die Aufgabe wird gemäss der Erfindung dadurch gelöst, dass bei dem eingangs näher bezeichneten Drehriegelspannverschluss der Schliessarm als Drehhaken ausgebildet ist, dass die Drehachse des Drehriegels in Langlöchern des Trägers gelagert ist oder der Drehriegel mit einem Langloch diese Drehachse umschliesst, wobei die Langlöcher sich in Richtung des Trägers bzw. Drehriegels erstrecken, dass die Länge des Verbindungsglieds zwischen dem Handhebel und dem Kurbelarm derart bemessen ist, dass während des letzten Teils des Schliessvorgangs eine Relativbewegung zwischen Langloch und Drehachse zustande kommt, und dass der Drehriegel in Schliessstellung durch einen Anschlag gegen Drehbewegung fixiert ist.The object is achieved according to the invention in that in the case of the rotary bolt tension lock described in the introduction, the locking arm is designed as a rotary hook, that the axis of rotation of the rotary bolt is mounted in elongated holes in the carrier, or that the rotary bolt encloses this rotational axis with an elongated hole, the elongated holes being in the direction of the carrier or rotary bolt extend that the length of the connecting member between the hand lever and the crank arm is dimensioned such that a relative movement between the elongated hole and the axis of rotation occurs during the last part of the closing process, and that the rotary bolt is fixed in the closed position by a stop against rotational movement is.

Beim erfindungsgemässen Drehriegelspannverschluss hintergreift beim Schliessvorgang der Drehhaken zunächst das Gegenelement am festen Aufbauteil, wobei das bewegliche Aufbauteil, wie z.B. eine Bordwand, eine Containertüre usw., zunächst in volle Anlage an das feste Aufbauteil gebracht wird. Während des weiteren Schliessvorgangs führt nun der Drehriegel eine Linearbewegung aus, so dass es zu einem Heranholvorgang in der Ebene des beweglichen Aufbauteils und zu einer Verspannung des beweglichen Aufbauteils in bezug auf das feste Aufbauteil kommt. Wesentlich ist beim erfindungsgemässen Drehriegelspannverschluss, dass dieser beim Schliessvorgang zunächst eine Drehbewegung und anschliessend eine Linearbewegung ausführt. Es liegt dabei innerhalb des Bereichs der Erfindung, dass sich diese beiden Bewegungen in gewissem Ausmass auch überlappen können.With the rotary latch tensioning lock according to the invention, when the rotary hook closes, the counter element first engages behind the fixed structural part, the movable structural part, such as e.g. a side wall, a container door, etc., is first brought into full contact with the fixed superstructure. During the further closing process, the rotary latch now carries out a linear movement, so that there is a pulling-up process in the plane of the movable structural part and tensioning of the movable structural part in relation to the fixed structural part. It is essential in the rotary bolt tension lock according to the invention that it first performs a rotary movement and then a linear movement during the closing process. It is within the scope of the invention that these two movements can also overlap to a certain extent.

Es gibt eine ausgedehnte Literatur über Spannverschlüsse, bei denen ein Haken ein Gegenelement hintergreift und bei denen der Haken im letzten Teil der Öffnungsbewegung auch eine Schwenkbewegung durchführt, um das Gegenelement freizugeben. Hierzu sei auf folgende Literatur verwiesen: FR-A-2261 396. Hier ist eine besonders für Fensterläden geeignete Schliessvorrichtung beschrieben, bei der der Haken aufgrund einer geeigneten Kulissenführung nach der Öffnungsbewegung vom Gegenelement abgehoben wird. Die DE-B-1099368 beschreibt einen Verschluss für die abklappbare und pendelbare Rückwand einer Bordwand von Lastkraftwagen, der einen an der Unterseite der hinteren Bordwand befestigten Drehzapfen verspannt. Beim Öffnen gleitet der schwenkbare Haken auf einem Gleitstück. Seine Unterseite besitzt eine derartige Kontur, dass der Haken am Ende seiner Öffnungsbewegung sich vom Drehzapfen an der Unterseite der Bordwand wegdreht. Ein ähnlicher Verschluss ist in der US-A-1 828797 dargestellt. Auch der aus der GB-A-1 925095 bekannte Hakenspannverschluss besitzt einen schwenkbaren Haken, der am Ende der Öffnungsbewegung vom Gegenelement weggeschwenkt wird. In der DE-C-1 143 737 ist ein Verschluss von Klappen, insbesondere von Laderampen an Flugzeugen, beschrieben, der ebenfalls nach der Öffnungsbewegung vom Gegenelement weggeschwenkt wird, wobei er auf einem Gleitstück gleitet, ähnlich wie bei dem aus der bereits erörterten DE-B-1099368 beschriebenen Verschluss. Verwiesen sei auch auf die FR-A-2 298 666, die einen Hakenspannverschluss zum gegenseitigen Verspannen der verschiedensten Teile beschreibt, wobei ein besonderer Mechanismus vorgesehen ist, der den Haken nach der Freigabe des Gegenelements von diesem wegschwenkt. Die US-A-3841 693 und US-A-4114718 zeigen speziell für kippbare Fahrerkabinen von Lastkraftwagen geeignete Spannverschlüsse, die einen verspannbaren Haken aufweisen, der beim Öffnen das Gegenelement nicht nur freigibt, sondern von diesem auch wegschwenkt. Allen gemeinsam ist diesen Verschlüssen die Tatsache, dass beim Schliessen die anfängliche Schwenkbewegung des Hakens nur dazu dient, diesen hinter das Gegenelement zu führen, wobei der Haken noch keinerlei Schliess- oder gar Verspannfunktion ausübt. Diese wird erst durch die folgende Linearbewegung des Hakens erreicht. Es handelt sich also in der Tat um Hakenspannverschlüsse, da beim eigentlichen Verriegelungsvorgang der Haken nur eine Linearbewegung macht. Beim erfindungsgemässen Drehriegelspannverschluss ist dagegen ein richtiger Drehriegel vorgesehen, der bereits beim ersten Teil des Schliessvorgangs als Drehriegel wirkt und der erst beim letzten Teil des Schliessvorgangs eine Linearbewegung macht.There is extensive literature on latches in which a hook engages behind a counter element and in which the hook also pivots in the last part of the opening movement in order to release the counter element. To this end, see the following References: FR-A-2261 396. This describes a locking device that is particularly suitable for shutters, in which the hook is lifted off the counter element after the opening movement due to a suitable slide guide. DE-B-1099368 describes a closure for the foldable and swingable rear wall of a side wall of trucks, which braces a pivot pin attached to the underside of the rear side wall. When opening, the swiveling hook slides on a slide. Its underside has such a contour that the hook turns away from the pivot on the underside of the side wall at the end of its opening movement. A similar closure is shown in US-A-1 828797. The hook tension lock known from GB-A-1 925095 also has a pivotable hook that is pivoted away from the counter element at the end of the opening movement. DE-C-1 143 737 describes a closure of flaps, in particular of loading ramps on aircraft, which is also pivoted away from the counter element after the opening movement, and slides on a slide, similar to that from the DE already discussed. B-1099368 described closure. Reference is also made to FR-A-2 298 666, which describes a hook-and-socket fastener for mutually bracing the most diverse parts, a special mechanism being provided which pivots the hook away from the counter element after it has been released. US-A-3841 693 and US-A-4114718 show latches which are particularly suitable for tiltable driver's cabins of trucks and which have a clampable hook which not only releases the counter element when it is opened, but also swings away from it. Common to all these closures is the fact that when the hook is initially pivoted, it only serves to guide it behind the counter element, the hook still not performing any closing or bracing function. This is only achieved by the following linear movement of the hook. It is indeed a matter of hook-and-loop fasteners, since the hook only makes a linear movement during the actual locking process. In the case of the rotary latch tension lock according to the invention, on the other hand, a correct rotary latch is provided which already acts as a rotary latch during the first part of the closing process and which only makes a linear movement during the last part of the closing process.

Die in Figur 1 bis 4 dargestellte Ausführungsform besitzt als Träger eine Einbauwanne 11, wie sie bei Verschlüssen der in Rede stehenden Art üblich ist. Unter einem zungenförmigen Fortsatz 12 an der Frontseite der Einbauwanne ist ein längsverschieblicher Lagerbock 13 für eine Anlenkachse 14 eines Handhebels 15 angeordnet, der durch eine sich an einem Block 16 abstützende Druckfeder 17 gegen die hintere Seitenwandung der Einbauwanne 11 gedrückt wird. Der Block 16 weist seitliche Ansätze 18 auf, die zusammen mit dem Fortsatz 12 und dem Boden der Wanne 11 eine Führung für den Lagerbock 13 ergeben.The embodiment shown in FIGS. 1 to 4 has a built-in trough 11 as a carrier, as is customary for closures of the type in question. Under a tongue-shaped extension 12 on the front of the installation trough, a longitudinally movable bearing block 13 for a pivot axis 14 of a hand lever 15 is arranged, which is pressed against the rear side wall of the installation trough 11 by a compression spring 17 supported on a block 16. The block 16 has lateral lugs 18 which, together with the extension 12 and the bottom of the trough 11, result in a guide for the bearing block 13.

Die gegen Federdruck verschiebbare Anordnung des Lagerbocks 13 ergibt eine federnde Anordnung des gesamten Schliessmechanismus, um zu verhindern, dass sich der Handhebel wegen zu grosser Entfernung des Gegenelements am festen Ausbauteil nicht mehr schliessen lässt. In einem solchen Fall kann der gesamte Schliessmechanismus gegen den Druck der Feder 17 nach vorne wandern.The arrangement of the bearing block 13, which is displaceable against spring pressure, results in a resilient arrangement of the entire locking mechanism in order to prevent the hand lever from being able to be closed due to the distance of the counter element on the fixed expansion part. In such a case, the entire locking mechanism can move forward against the pressure of the spring 17.

An der Unterseite des Handhebels 15 befinden sich zwei Rippen 19, mit deren Hilfe der Handhebel an der Anlenkachse 14 schwenkbar befestigt ist. Hinterhalb der Anlenkachse 14 befinden sich zwei kurze Anlenkachsen 20, mit deren Hilfe zwei Verbindungsglieder 21 an den Rippen 19 des Handhebels 15 angelenkt sind. Am anderen Ende sinddieVerbindungsglieder21 durch eineAnienkachse 22 miteinander verbunden. Diese Anlenkachse durchquert das freie Ende eines Kurbelarms 25 eines Drehhakens 23, der um eine Drehachse 24 drehbar ist. Die fest mit dem Drehhaken 23 verbundene Drehachse 24 ist in Langlöchern geführt, die in den Seitenwandungen der Einbauwanne 11 ausgebildet sind.On the underside of the hand lever 15 there are two ribs 19, by means of which the hand lever is pivotably attached to the articulation axis 14. Behind the articulation axis 14 there are two short articulation axes 20, by means of which two connecting links 21 are articulated on the ribs 19 of the hand lever 15. At the other end, the connecting links 21 are connected to one another by an axle 22. This articulation axis passes through the free end of a crank arm 25 of a rotary hook 23, which is rotatable about an axis of rotation 24. The axis of rotation 24, which is fixedly connected to the rotary hook 23, is guided in elongated holes which are formed in the side walls of the installation trough 11.

Die Länge der Verbindungsglieder 21 ist derart bemessen, dass während des Schliessvorgangs nach beendeter Drehbewegung des Drehriegels 23 der Handhebel 15 noch nicht geschlossen ist, so dass die Verbindungsglieder 21 beim weiteren Schliessen des Handhebels 15 auf den Drehhaken 23 nur mehr eine Zugbewegung und kein Drehmoment mehr ausüben. Beim letzten Teil des Schliessvorgangs macht deshalb der Drehhaken 23 nur mehr eine Linearbewegung. Dabei stützt er sich mit einem unteren Vorsprung 27 am Boden der Einbauwanne 11 ab. Diese weist an ihrem vorderen Ende wie üblich eine Absenkung 28 auf, so dass es nicht nötig ist, ein seitliches Einfassprofil der Bordwand beim Einbau des Verschlusses an der Frontseite der Bordwand aufzuschneiden. In diesem vorderen Bereich besitzt die Einbauwanne 11 an ihrem Boden eine Ausnehmung 29, um eine Drehbewegung des Drehhakens 23 zu ermöglichen.The length of the connecting links 21 is dimensioned such that during the closing process after the rotary movement of the rotary latch 23 has ended, the hand lever 15 is not yet closed, so that when the hand lever 15 is further closed on the rotary hook 23, the connecting links 21 only have a pulling motion and no more torque exercise. In the last part of the closing process, the rotary hook 23 therefore only makes a linear movement. He is supported with a lower projection 27 on the bottom of the installation tray 11. As usual, this has a depression 28 at its front end, so that it is not necessary to have a lateral one Cut the border profile of the drop side when installing the lock on the front of the drop side. In this front area, the installation trough 11 has a recess 29 on its base in order to enable the rotary hook 23 to rotate.

Auf der Anlenkachse 22 wird der richtige Abstand zwischen den Verbindungsgliedern 21 und dem Kurbelarm 25 durch Abstandsbuchsen 30 besorgt. Am Boden der Einbauwanne 21 sind ausserdem zwei senkrecht stehende Laschen 31 befestigt, die einen Einschnitt 32 aufweisen, derart, dass die Oberseite der Lasche 31 als Niederhaltnase 33 für die Anlenkachse 22 dient. Wenn durch Innendruck auf die Bordwand auf den Drehhaken 23 ein Drehmoment ausgeübt wird, dann wird durch die Niederhaltnase 33 der Schliessmechanismus entlastet.On the pivot axis 22, the correct distance between the connecting members 21 and the crank arm 25 is provided by spacer bushings 30. In addition, two vertically standing tabs 31 are fastened to the bottom of the installation trough 21 and have an incision 32 such that the upper side of the tab 31 serves as a hold-down nose 33 for the articulation axis 22. If a torque is exerted on the rotating hook 23 by internal pressure on the drop side, then the locking mechanism is relieved by the hold-down nose 33.

Die Ausführungsform der Figuren 5 bis 9 entspricht weitgehend derjenigen der Figuren 1bis4.The embodiment of FIGS. 5 to 9 largely corresponds to that of FIGS. 1 to 4.

Der wesentliche Unterschied besteht darin, dass die Laschen 31 mit ihren Niederhaltnasen 33 fehlen und dass der Drehhaken 23 keinen Vorsprung 27 aufweist. Die Entlastung des Schliessmechanismus erfolgt hier auf andere Weise. Es ist ein Schieber 34 vorgesehen, der sich beim Bewegen des Drehhakens 23 in Schliessstellung unter diesen schiebt und ihn abstützt. Für die Bewegung des Schiebers sind zwei Schubglieder 35 vorgesehen, die einerseits am Handhebel 15 und andererseits am Schieber 34 angelenkt sind. Für die Anlenkung am Schieber dienen zwei aufrechtstehende Laschen 36. Der Schieber verschliesst in der Schliessstellung die Ausnehmung 29 und stützt den Drehhaken 23 auf fast seiner gesamten Länge ab.The main difference is that the tabs 31 with their hold-down lugs 33 are missing and that the rotary hook 23 has no projection 27. The locking mechanism is relieved in a different way. A slider 34 is provided which, when the rotary hook 23 is moved in the closed position, slides under it and supports it. For the movement of the slide, two thrust members 35 are provided, which are articulated on the one hand on the hand lever 15 and on the other hand on the slide 34. Two upright tabs 36 are used for articulation on the slide. The slide closes the recess 29 in the closed position and supports the rotary hook 23 over almost its entire length.

Es ist auch möglich, den Schieber 34 lediglich durch eine Feder in Richtung des Drehhakens zu schieben, so dass ein eigener Bewegungsmechanismus für den Schieber in Wegfall kommt. Der Schieber wird bei dieser Ausführungsform zur Freigabe der Ausnehmung 29 beim Öffnen des Verschlusses durch den sich drehenden Drehhaken 23 selbsttätig zurückgeschoben. Hierzu sollte natürlich die Unterseite des Drehhakens 23 eine geeignete Kontur aufweisen.It is also possible to push the slide 34 in the direction of the rotary hook only by means of a spring, so that a separate movement mechanism for the slide is eliminated. In this embodiment, the slide is automatically pushed back by the rotating rotary hook 23 to release the recess 29 when the closure is opened. Of course, the underside of the rotary hook 23 should have a suitable contour for this purpose.
