Abstract

1. A releasable hinge arrangement on a foldable hatch covering aboard ship, of which any two hatch covers (1, 2) involved may from a closed state lying side by side be moved relative to one another through 180 degrees into an upright parallel open position and have hinge eyes (4, 5) associated with one another, which in the operational state receive in openings aligned with one another a hingepin (6) which for release may be brought out of engagement with the hinge eye on the one hatch cover, characterized in that the hinge eye (4) on the one hatch cover (1) is made U-shaped and in the closed state of the hatch covers (1, 2) allows the escape of the hingepin (6) held in the hinge eye (5) of the other hatch cover (2), and that on the hinge eye (5) of the other hatch cover (2) a locking cam (7) is arranged concentric with the hingepin (6) in the form of an annular segment which in any state of the hatch covers (1, 2) between folded at all and folded together engages behind an axial thickening (4a) with a circular outer contour on the hinge eye (4) on the one hatch cover (1) and prevents the escape of the hingepin (6).

Description

Die Erfindung betrifft eine lösbare Scharnieranordnung an faltbaren Lukendeckeln für Schiffsluken, mit einander zugeordneten, an den beiden jeweils beteiligten Lukendeckeln vorgesehenen Scharnieraugen, die im Betriebszustand bei miteinander fluchtenden öffnungen einen Scharnierbolzen aufnehmen, welcher zum Lösen außer Eingriff mit dem Scharnierauge des einen Lukendeckels gebracht werden kann.The invention relates to a releasable hinge arrangement on foldable hatch covers for ship hatches, with hinge eyes which are assigned to one another and are provided on the two hatch covers involved and which, in the operating state, accommodate a hinge pin when the openings are aligned with one another, which can be brought out of engagement with the hinge eye of the one hatch cover for loosening .

Eine derartige Scharnieranordnung ist aus der DE-PS 12 56 105 (Spalte 4, Zeile 67 bis Spalte 5, Zeile 5) als mögliche Alternative einer Vorrichtung bekannt, mit deren Hilfe wahlweise jeweils einer von zwei Scharnierbolzen in die miteinander fluchtenden öffnungen von Scharnieraugen eingeführt werden kann, die an unterschiedlichen Punkten eines Paares von Lukendeckeln angebracht sind. Im völlig getrennten Zustand der beiden Lukendeckel kann jeder einzelne Deckel aus dem Paarungs- oder gar weitergehenden Kopplungsverbund der Luckenabdeckung herausgenommen werden, um im Bedarfsfalle eine partielle öffnung der Luke zu erlauben, so daß beispielsweise Container an bestimmten Stellen der Luke geladen oder gelöscht werden können.Such a hinge arrangement is known from DE-PS 12 56 105 (column 4, line 67 to column 5, line 5) as a possible alternative to a device with the aid of which one of two hinge bolts can optionally be inserted into the aligned openings of hinge eyes can, which are attached to different points of a pair of hatch covers. In the completely separate state of the two hatch covers, each individual cover can be removed from the pairing or even more extensive coupling assembly of the gap cover, in order to allow partial opening of the hatch if necessary, so that, for example, containers can be loaded or unloaded at certain points of the hatch.

Das Lösen der Scharnierverbindung durch Herausziehen der Scharnierbolzen hat jedoch praktische Nachteile. Der Scharnierbolzen ist im allgemeinen radial wirkenden Kräften ausgesetzt, welche seiner axialen Bewegung Widerstand entgegensetzen. Es kommt hinzu, daß sich die dem Auffalten (im Gegensatz zum Aufklappen) der Deckel eines Lukendeckelpaares dienenden Scharniere zwangsläufig unterhalb der Lukendeckel befinden und daher bei geschlossener Luke nur vom Laderaum zugänglich sind. Man kann die Scharniere auch nicht so weit an der Außenseite der Lukendeckel anordnen, daß sie von außen her zugänglich sind, weil dies eine sperrige Konstruktion erforderte, welche die Platzverhältnisse an der Süllbank im allgemeinen nicht erlauben.However, loosening the hinge connection by pulling out the hinge pin has practical disadvantages. The hinge pin is generally subjected to radially acting forces which resist its axial movement. In addition, the hinges serving to unfold (as opposed to opening) the covers of a pair of hatch covers are inevitably located below the hatch covers and are therefore only accessible from the hold when the hatch is closed. The hinges cannot be placed so far on the outside of the hatch cover that they are accessible from the outside, because this required a bulky construction, which generally does not allow the space on the bench.

Der Erfindung liegt daher die Aufgabe zugrunde, eine lösbare Scharnieranordnung anzugeben, welche einerseits das Herausnehmen eines Lukendeckels aus einem paarweise aufgebauten Lukendeckelverbund (wenn sich dieser in seinem Schließzustand befindet) unschwer erlaubt, andererseits das sichere Auffalten der aneinander angelenkten Lukendeckel nicht beeinträchtigt.The invention is therefore based on the object of specifying a detachable hinge arrangement which, on the one hand, allows easy removal of a hatch cover from a pair of hatch cover assemblies (when it is in its closed state), and on the other hand does not impair the safe unfolding of the hinged hatch covers hinged to one another.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Scharnierauge des einen Lukendeckels U-förmig ausgebildet ist und im Schließzustand der Lukendeckel den Austritt des im Scharnierauge des anderen Lukendeckels gehaltenen Scharnierbolzens erlaubt, und daß am Scharnierauge des anderen Lukendeckels ein Sperrnocken angeordnet ist, der im an- bis aufgefalteten Zustand der Lukendeckel das Scharnierauge des einen Lukendeckels untergreift und den Austritt des Scharnierbolzens verhindert. Wird der 'andere' Lukendeckel - ohne Faltneigung zum benachbart angelenkten, 'einen' Lukendeckel - angehoben so können die koaxial liegenden Scharnierbolzen der (naturgemäß mehreren vorgesehenen) Scharniere aus den nach oben offenen U-förmigen Scharnieraugen (die eigentlich keine 'Augen' mehr sind) an jenem 'einen' Lukendeckel austreten, so daß die Scharnierverbindung gelöst ist. Auf entsprechend umgekehrtem Wege läßt sich die Scharnierverbindung auch wiederherstellen.This object is achieved in that the hinge eye of one hatch cover is U-shaped and in the closed state of the hatch cover allows the exit of the hinge pin held in the hinge eye of the other hatch cover, and that a locking cam is arranged on the hinge eye of the other hatch cover - Until the hatch cover is unfolded, it engages under the hinge eye of one hatch cover and prevents the hinge pin from escaping. If the 'other' hatch cover - without folding towards the adjacent, 'one' hatch cover - is raised, the coaxial hinge pins of the (naturally several provided) hinges emerge from the upwardly open U-shaped hinge eyes (which are actually no longer 'eyes') on that 'hatch cover' so that the hinge connection is released. The hinge connection can also be restored in a correspondingly opposite way.

Werden hingegen die beiden Lukendeckel gemeinsam unter Bildung eines (von 180° abweichenden) Faltwinkels angehoben, so wird mit Hilfe des Sperrnockens die Scharnierverbindung verriegelt und bleibt dies auch in der völlig aufgefalteten Lukendeckel-Position, in der die Lukendeckel parallel zueinander senkrecht stehen. Erst im völlig entfalteten Zustand, wenn die beiden Lukendeckel wieder fluchtend nebeneinander liegen, kommt der - ebenso wie der Scharnierbolzen am 'anderen' Lukendeckel angebrachte - Sperrnocken wieder außer Eingriff mit dem U-förmigen Scharnierauge am 'einen' Lukendeckel, so daß ein Lösen der Scharnierverbindung erneut möglich wäre.If, on the other hand, the two hatch covers are raised together to form a folding angle (which deviates from 180 °), the hinge connection is locked with the help of the locking cam and remains in the fully unfolded hatch cover position, in which the hatch covers are parallel to each other parallel. Only in the fully unfolded state, when the two hatch covers are aligned again, does the locking cam - like the hinge pin attached to the 'other' hatch cover - come out of engagement with the U-shaped hinge eye on 'one' hatch cover, so that the hatch can be released Hinge connection would be possible again.

Eine Weiterbildung der Erfindung sieht eine lösbare Verriegelungseinrichtung vor, die auch im Schließzustand der Lukendeckel den Austritt des Scharnierbolzens aus dem U-förmigen Scharnierauge des einen Lukendeckels verhindert. Eine solche Verriegelungseinrichtung kann als Sicherheitsmaßnahme gegen unbeabsichtigtes Lösen der Scharnierverbindung beispielsweise dann vorgesehen werden, wenn die Gefahr besteht, daß beim rollenden Verfahren der fluchtend nebeneinander angeordneten beiden Lukendeckel über der Lukenöffnung der andere Lukendeckel aufgrund einer Unebenheit in den Rollbahnen hochspringt und dabei die Scharnierbolzen aus den U-förmigen Scharnieraugen des einen Lukendeckels ungewollt aushaken.A further development of the invention provides a releasable locking device which prevents the hinge pin from escaping from the U-shaped hinge eye of one hatch cover even when the hatch cover is closed. Such a locking device can be provided as a safety measure against unintentional loosening of the hinge connection, for example, if there is a risk that during the rolling process of the two hatch covers arranged in alignment next to one another, the other hatch covers will jump up over the hatch opening due to an unevenness in the runways and thereby remove the hinge bolts from the Unintentionally unhook U-shaped hinge eyes on one hatch cover.

Eine derartige Verriegelungseinrichtung kann vorteilhaft so ausgebildet sein, daß am einen Lukendeckel ein parallel zur Scharnierachse aus einer Ruhe- in eine Arbeitsstellung verschieblicher Stift angeordnet ist, der in seiner Arbeitsstellung an einer am anderen Lukendeckel befestigten Kulisse anliegt. Vorzugsweise hat dann die Kulisse die Form eines Abschnitts aus einem Kreis um die Scharnierachse, welcher so groß ist, daß der in seiner Arbeitsstellung befindliche Stift bei Erreichen eines vorbestimmten Faltwinkels der Lukendeckel außer Eingriff mit der Kulisse kommt. Denn wenn man aus Gründen der besseren Zugänglichkeit den Stift in einem Querabstand zur Scharnierachse anordnet, dann beschreibt er - an einem der beiden Lukendeckel gehalten - beim Auffalten einen Kreisbogen relativ zum angelenkten Lukendeckel, an dem die Kulisse sitzt. Da kurz nach Beginn des Faltens der Sperrnocken die Verriegelung der Scharnierverbindung übernimmt, kann alsdann die Verriegelung zwischen Stift und Kulisse wirkungslos werden.Such a locking device can advantageously be designed in such a way that a pin which is displaceable parallel to the hinge axis from a rest position into a working position is arranged on one hatch cover and in its working position rests against a link attached to the other hatch cover. The backdrop then preferably has the shape of a section from a circle around the hinge axis, which is so large that the pin in its working position comes out of engagement with the backdrop when a predetermined folding angle of the hatch cover is reached. Because if, for reasons of better accessibility, the pin is arranged at a transverse distance from the hinge axis, then it describes - held on one of the two hatch covers - when unfolding a circular arc relative to the hinged hatch cover on which the backdrop sits. Since the hinge connection is locked shortly after the locking cams begin to fold, the locking between pin and link can then be ineffective.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand zusätzlicher Unteransprüche.Further advantageous embodiments of the invention are the subject of additional subclaims.

Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel, und zwar zeigt:

The drawing illustrates the invention using an exemplary embodiment, namely:
  • Figure 1 in plan view a pair of hinged hatch covers with hinges arranged on the underside, in the closed state of the hatch cover.
  • 2 with solid lines a side view of the hatch cover pair shown in FIG. 1 and with dash-dotted lines two different opening positions of the hatch covers involved;
  • 3 shows a hinge (alone) in a side view;

  • 5 shows a locking device in a side view; and
  • Fig. 6 is a plan view of the locking device.

Zwei Lukendeckel 1, 2 sind in der üblichen Weise in ihrem in den Figuren 1 und 2 (dort mit ausgezogenen Linien) dargestellten Schließzustand (= Luke abgedeckt) fluchtend nebeneinander angeordnet und durch zwei Scharniere miteinander verbunden, die im ganzen mit 3 bezeichnet sind. In der Praxis ist das aus den Lukendeckeln 1, 2 gebildete Lukendeckelpaar meist Bestandteil eines größeren Lukendeckel-Verbundes; hierauf kommt es im vorliegenden Zusammenhang aber nicht an.Two hatch covers 1, 2 are arranged in alignment in the usual manner in their closed state (= hatch covered) shown in FIGS. 1 and 2 (there with solid lines) and connected to one another by two hinges, which are denoted as a whole by 3. In practice, the hatch cover pair formed from hatch covers 1, 2 is usually part of a larger hatch cover assembly; this is not important in the present context.

Die Scharniere 3, die zu diesem Zweck an der Unterseite der Lukendeckel 1, 2 angeordnet sind, erlauben ein umgekehrt V-förmiges Auffalten der Lukendeckel gegeneinander, so daß diese schließlich die in Figur 2 links strichpunktiert dargestellte parallele Relativlage einnehmen, in der sie den Zugang zu dem Abschnitt des Laderaums freigeben, den sie im Schließzustand überdecken.The hinges 3, which are arranged for this purpose on the underside of the hatch covers 1, 2, allow the hatch covers to be folded up in a reverse V-shape, so that they finally assume the parallel relative position shown in broken lines in FIG. 2, in which they have access to the section of the cargo space that they cover when closed.

Jedes Scharnier 3 besteht aus einem Scharnierauge 4, welches an dem 'einen' Lukendeckel 1 angeschweißt und - im Schließzustand der Lukendeckel nach oben offen - U-förmig ausgebildet ist, sowie aus zwei Scharnieraugen 5, die am 'anderen' Lukendeckel 2 angeschweißt sind und den Scharnierbolzen 6 zwischen sich (ebenfalls verschweißt) halten. Im geschlossenen Zustand der SCharniere 3, welcher in den Figuren 1, 2 (ausgezogene Linien), 3 und 4 dargestellt ist, befindet sich der Scharnierbolzen 6 im Scharnierauge 4 des Lukendeckels 1, wobei das Scharnierauge 4 sich parallel zwischen die Scharnieraugen 5 des Lukendeckels 2 erstreckt.Each hinge 3 consists of a hinge eye 4, which is welded to the 'one' hatch cover 1 and - in the closed state of the hatch cover is open at the top - U-shaped, and two hinge eyes 5 which are welded to the 'other' hatch cover 2 and hold the hinge pin 6 between them (also welded). When the hinges 3 are closed, which one 1, 2 (solid lines), 3 and 4, the hinge pin 6 is located in the hinge eye 4 of the hatch cover 1, the hinge eye 4 extending parallel between the hinge eyes 5 of the hatch cover 2.

Jeweils an der dem Scharnierauge 4 zugekehrten Seitenwand jedes Scharnierauges 5 sind Sperrnocken 7 angeordnet, welche in der Seitenansicht die am besten der Figur 3 entnehmbare Form eines Kreisring-Ausschnitts haben. Dabei ist die Scharnierachse 8 Kreismittelpunkt, und der Sperrnocken 7 ist konzentrisch zu der kreisförmigen Außenkontur des Scharnierauges 4 angeordnet (wenn sich der Scharnierbolzen 6 im Scharnierauge 4 befindet). Ein Knotenblech 9 dient zur Befestigung des Scharnierauges 4 am Lukendeckel 1; und es sei darauf hingewiesen, daß in Figur 1 sowohl die der Figur 4 entnehmbaren axialen Verdickungen des Scharnierauges 4 gegenüber dem Knotenblech 9 als auch die Sperrnocken 7 aus Gründen der Übersichtlichkeit weggelassen sind.In each case on the side wall of the hinge eye 4 facing each hinge eye 5, locking cams 7 are arranged which, in the side view, have the shape of a circular ring cutout best seen in FIG. 3. The hinge axis 8 is the center of the circle, and the locking cam 7 is arranged concentrically with the circular outer contour of the hinge eye 4 (when the hinge pin 6 is in the hinge eye 4). A gusset plate 9 is used to fasten the hinge eye 4 to the hatch cover 1; and it should be pointed out that in FIG. 1 both the axial thickenings of the hinge eye 4 in relation to the gusset plate 9, which can be seen in FIG. 4, and the locking cams 7 are omitted for reasons of clarity.

Figur 2 veranschaulicht mit der strichpunktierten Darstellung oberhalb der mit ausgezogenen Linien gezeichneten Darstellung, daß der Lukendeckel 2 in Pfeilrichtung aus seiner Scharnierverbindung mit dem Lukendeckel 1 herausgehoben werden kann, ohne daß sich der Lukendeckel 1 mitbewegt. Dabei tritt der von den Scharnieraugen 5 gehaltene Scharnierbolzen 6 aus dem U-förmigen Scharnierauge 4 am Lukendeckel 1 aus; der Sperrnocken 7 hindert diesen Vorgang ersichtlich nicht.FIG. 2 illustrates with the dash-dotted representation above the representation drawn with solid lines that the hatch cover 2 can be lifted out of its hinge connection with the hatch cover 1 in the direction of the arrow without the hatch cover 1 also moving. The hinge pin 6 held by the hinge eyes 5 emerges from the U-shaped hinge eye 4 on the hatch cover 1; the locking cam 7 obviously does not prevent this process.

Wenn man hingegen das von den Lukendeckeln 1, 2 gebildete Deckelpaar (umgekehrt V-förmig) anfaltet, beispielsweise indem man den Lukendeckel 1 - in Figur 2 im Gegenuhrzeisersinne - kippt, dann wird der Lukendeckel 2 mitgenommen, wobei der Scharnierbolzen 6 sich im Scharnierauge 4 dreht. Hierdurch wird gleichzeitig der Sperrnocken 7 um das Scharnierauge 4 herumbewegt, so daß er nun den Austritt des Scharnierbolzens 6 aus dem Scharnierauge 4 blockiert (ohne die Drehung des Scharnierbolzens 6 im Scharnierauge 4 zu behindern). Am Ende des Faltvorganges haben die Lukendeckel 1, 2 dann die in Figur 2 links strichpunktiert dargestellte Relativstellung erreicht.If, on the other hand, you fold the cover pair formed by the hatch covers 1, 2 (reversely V-shaped), for example by tilting the hatch cover 1 - in the counterclockwise direction in FIG. 2 - the hatch cover 2 is then taken along, the hinge pin 6 rotating in the hinge eye 4. As a result, the locking cam 7 is simultaneously moved around the hinge eye 4, so that it now blocks the exit of the hinge pin 6 from the hinge eye 4 (without hindering the rotation of the hinge pin 6 in the hinge eye 4). At the end of the folding process, the hatch covers 1, 2 have then reached the relative position shown in dash-dotted lines in FIG. 2.

Theoretisch könnte der Sperrnocken 7 in Umfangsrichtung des Kreisring-Ausschnitts relativ kurz sein, wobei seine Umfangserstreckung stets an oder kurz oberhalb der in Figur 3 strichpunktierten Horizontalen durch die Scharnierachse 8 (= Parallele zur Hauptebene des Lukendeckels 2 durch die Scharnierachse 8) beginnt. Da jedoch einerseits ein gewisses Spiel zwischen dem Sperrnocken 7 und dem Scharnierauge 4 vorgesehen sein muß und andererseits ein zu kurzer Nocken leichter beschädigt werden könnte, zeigt das Ausführungsbeispiel einen Sperrnocken 7, der sich über etwas mehr als 90° um das Scharnierauge 4 erstreckt.Theoretically, the locking cam 7 could be relatively short in the circumferential direction of the circular ring cutout, its circumferential extension always beginning at or just above the horizontal-dashed line in FIG. 3 through the hinge axis 8 (= parallel to the main plane of the hatch cover 2 through the hinge axis 8). However, since on the one hand a certain play must be provided between the locking cam 7 and the hinge eye 4 and on the other hand a cam that is too short could be more easily damaged, the exemplary embodiment shows a locking cam 7 which extends over a little more than 90 ° around the hinge eye 4.

An den Lukendeckeln 1, 2 sind ferner Verriegelungseinrichtungen vorgesehen, die im ganzen mit 10 bezeichnet sind, und deren Aufbau im einzelnen den Figuren 5 und 6 entnehmbar ist. Die Verriegelungseinrichtungen dienen in der oben geschilderten Weise dazu, die Anlenkung der Lukendeckel 1, 2 aneinander mit Hilfe der Scharniere 3 gegen unbeabsichtigtes Lösen der Scharnierverbindung zu sichern.Locking devices are also provided on the hatch covers 1, 2, which are designated as a whole by 10, and whose structure can be seen in detail in FIGS. 5 and 6. In the manner described above, the locking devices serve to secure the articulation of the hatch covers 1, 2 to one another by means of the hinges 3 against unintentional loosening of the hinge connection.

Am ('anderen') Lukendeckel 2 ist (an jeder Seite) seitlich eine Kulisse 11 angebracht, welche die Form eines Abschnittes aus einem Kreis um die Scharnierachse 8 hat (Fig. 5). Seitlich (wiederum an jeder Seite) ist am ('einen') Lukendeckel 1 mit Hilfe eines Armes 12 eine Hülse 13 gehalten, die einen Stift 14 in Richtung seiner Achse 15 längsverschieblich führt, wobei die Achse 15 parallel zur Scharnierachse 8 verläuft (und sich in Beispiel senkrecht über dieser befindet, wenn Lukendeckel 1, 2 ihren Schließzustand einnehmen). Eine am Stift 14 radial angebrachte Stange 16 durchsetzt einen U-förmigen Ausschnitt 17 in der Hülse 13. Mit dem Ausschnitt 17 begrenzt die Stange 16, die gleichzeitig als Handhebel für den Stift 14 dient, dessen axialen Verschiebeweg. Befindet sich die Stange 16 im Lukendeckel-nahen Schenkel des U-förmigen Ausschnitts 17, so übergreift der Stift 14 die Kulisse 11 (Fig. 6) ; befindet sie sich im anderen Schenkel des Ausschnitts 17, so ist keine vertikale Uberdeckunc von Kulisse 11 und Stift 14 gegeben.On the ('other') hatch cover 2 (on each side) is laterally attached a link 11, which has the shape of a section from a circle around the hinge axis 8 (FIG. 5). Laterally (again on each side) is held on the ('a') hatch cover 1 by means of an arm 12, a sleeve 13 which guides a pin 14 longitudinally displaceable in the direction of its axis 15, the axis 15 running parallel to the hinge axis 8 (and in the example vertically above it when hatch covers 1, 2 are in their closed state). A rod 16 radially attached to the pin 14 passes through a U-shaped cutout 17 in the sleeve 13. With the cutout 17, the rod 16, which at the same time serves as a hand lever for the pin 14, delimits its axial displacement path. If the rod 16 is located in the leg of the U-shaped cutout 17 near the hatch cover, the pin 14 engages over the link 11 (FIG. 6); they are located in the other leg of the cutout 17, so no vertical U is berdeckunc of slide 11 and, pin fourteenth

Wenn die Stifte 14 gegenüber den zugehörigen Kulissen 11 der Verriegelungseinrichtungen 10 die in den Figuren 1 und 6 dargestellte Verriegelungsstellung einnehmen, dann verhindert die Anlage der Kulissen 11 an den zugehörigen Stiften 14 das Lösen der Scharnierverbindung zwischen den Lukendeckeln 1, 2 durch Herausbewegen der Scharnierbolzen 6 aus den Scharnieraugen 4 (rechte strichpunktierte Stellung in Fig. 2) auch im Schließzustand der Lukendeckel 1, 2, wie er den Figuren 1 und 2 (ausgezogene Linien) sowie entsprechend den Figuren 3 bis 6 zugrunde liegt. Die Kreisabschnittsform der Kulissen 11 mit der Scharnierachse 8 als Mittelpunkt behindert nicht die relative Faltbewegung der Lukendeckel 1,2, vielmehr bewegt sich der in seiner Verriegelungsstellung befindliche Stift 14 entlang der Kreisoberfläche der Kulisse 11. Da bei der Faltbewegung - wie vorstehend dargelegt - der Sperrnocken 7 in eine Stellung gelangt, in der er das Öffnen der Scharnierverbindung blockiert und insoweit die Funktion der Verriegelungseinrichtung 10 übernimmt, bedarf es beim darüber hinausgehenden Faltvorgang nicht mehr dieser Verriegelungsfunktion. Die verriegelnde Relativlage von Kulisse 11 und Stift 14 braucht also nur über einen relativ kleinen Teil des Faltvorganges erhalten zu bleiben, und die Größe des die Kulisse 11 bildenden Kreis-abschnitts ist entsprechend gewählt. Beim weiteren Falten verläßt der Stift 14 die Kulisse 11, so daß diese Bauteile schließlich - in gänzlich zusammengefaltetem Zustand des aus den Lukendeckeln 1, 2 gebildeten Lukendeckelpaares-die in Fig. 2 links strichpunktiert gezeichnete Relativstellung einnehmen.If the pins 14 assume the locking position shown in FIGS. 1 and 6 relative to the associated scenes 11 of the locking devices 10, then the contact of the scenes 11 with the associated pins 14 prevents the hinge connection between the hatch covers 1, 2 from being released by moving the hinge bolts 6 out from the hinge eyes 4 (right dash-dotted position in Fig. 2) also in the closed state of the hatch covers 1, 2, as is the basis of Figures 1 and 2 (solid lines) and corresponding to Figures 3 to 6. The circular section shape of the scenes 11 with the hinge axis 8 as the center does not hinder the relative folding movement of the hatch covers 1, 2, rather, the pin 14 located in its locking position moves along the circular surface of the link 11. Since during the folding movement - as explained above - the locking cam 7 comes into a position in which it blocks the opening of the hinge connection and in this respect takes over the function of the locking device 10 , this locking function is no longer required for the folding process beyond that. The locking relative position of the link 11 and pin 14 thus only needs to be maintained over a relatively small part of the folding process, and the size of the circular section forming the link 11 is chosen accordingly. Upon further folding, the pin 14 leaves the backdrop 11, so that these components finally - in the completely folded state of the hatch cover pair formed from the hatch covers 1, 2 - assume the relative position shown in dash-dotted lines on the left in FIG. 2.

Soll - ausgehend vom Schließzustand der Lukendeckel 1, 2 - der Lukendeckel 2 allein abgehoben werden, dann werden die Stifte 14 mit Hilfe der Stangen 16 axial zurückgezogen, so daß die Kulissen 11 am Lukendeckel 2 ungehindert passieren können.If - starting from the closed state of the hatch covers 1, 2 - the hatch cover 2 is to be lifted off by itself, then the pins 14 are withdrawn axially with the aid of the rods 16, so that the scenes 11 on the hatch cover 2 can pass unhindered.
