Description

Die vorliegende Erfindung betrifft ein Kältegerät mit einem Korpus und mit zwei Türen, die jeweils mit einer ihrer Kanten an entgegengesetzten Seiten einer Öffnung des Korpus angeschlagen sind.The present invention relates to a refrigerator having a body and having two doors each struck with one of its edges on opposite sides of an opening of the body.

Bei einem solchen Kältegerät besteht ein Problem darin, dass ein sich quer durch die Öffnung des Korpus erstreckender Holm erforderlich ist, um eine Auflagefläche zu schaffen, an der die Türen in geschlossener Stellung dicht anliegen können. Wenn ein solcher Holm fest in dem Korpus montiert ist, so behindert er den Zugang zum Innenraum des Kältegeräts, wenn beide Türen gleichzeitig geöffnet sind. Wenn der Holm starr an einer der Türen befestigt ist, so kann diese Tür nur geöffnet werden, wenn die andere bereits offen ist, was für den freien Zugriff auf den Innenraum ebenfalls hinderlich ist. Ein Kältegerät nach dem Oberbegriff des Anspruchs 1 ist aus US 5 411 328 bekannt.A problem with such a refrigerator is that a spar extending transversely through the opening of the body is required to provide a support surface against which the doors can tightly engage in the closed position. If such a spar is fixedly mounted in the body, it hinders access to the interior of the refrigerator when both doors are open at the same time. If the bar is rigidly attached to one of the doors, then this door can only be opened when the other is already open, which is also a hindrance to the free access to the interior. A refrigerator according to the preamble of claim 1 is made US 5,411,328 known.

Aus US 4 711 098 ist ein zweitüriges Kältegerät bekannt, bei dem ein Holm an eine Kante der ersten Tür angelenkt ist, die deren angeschlagener Kante gegenüber liegt. Der Holm ist schwenkbar zwischen einer ersten Stellung, in welcher die geschlossene zweite Tür dicht an ihm anliegt, und einer zweiten Stellung, in der er vollständig hinter die erste Tür geschwenkt ist, so dass diese geöffnet werden kann, ohne dabei die zweite Tür mitzunehmen. Die Schwenkbewegung des Holms ist geführt durch einen Führungsvorsprung des Holms, der in einer am Rand der Öffnung des Korpus gebildeten Führungsnut verschiebbar ist, und den Holm zu einer an die Öffnungsbewegung der ersten Tür gekoppelten Schwenkbewegung zwingt.Out US 4,711,098 is a two-door refrigeration device is known in which a spar is hinged to an edge of the first door, which lies opposite the battered edge. The spar is pivotable between a first position in which the closed second door is close to it, and a second position in which it is fully pivoted behind the first door, so that it can be opened without taking the second door. The pivoting movement of the spar is guided by a guide projection of the spar, which is displaceable in a guide groove formed on the edge of the opening of the body, and forces the spar to a pivoting movement coupled to the opening movement of the first door.

Ein Problem dieses Kältegeräts ist, dass der Holm, um beim Schließen der ersten Tür zuverlässig in die Öffnung des Korpus einzurücken, in seiner Längsrichtung spielhaltig sein muss. D. h. zwischen den Stirnseiten des Holms und einer diesen Stirnseiten zugewandten Oberfläche des Korpus, in welcher die Führungsnut gebildet ist, sowie zwischen der Spitze des Führungsvorsprungs und dem Boden der Nut, in die er eingreift, muss ein Spalt vorhanden sein, dessen Breite in der Praxis mehrere Millimeter beträgt. Sofern nicht eine Seitenwand des Vorsprungs auf ihrer gesamten Länge dicht an einer Seitenwand der Nut anliegt, kann auch bei geschlossenen Türen Luft in den Innenraum des Kältegeräts fließen. Die daraus resultierende starke Zufuhr von Wärme und Feuchtigkeit macht den Energieverbrauch des Kältegeräts hoch.A problem of this refrigeration device is that the spar, in order to engage reliably in the opening of the body when closing the first door, must be playable in its longitudinal direction. Ie. between the end faces of the spar and a front surface facing the body in which the guide groove is formed, as well as between the tip of the guide projection and the bottom of the groove, in which it engages, a gap must be present, whose width in practice more Millimeters. Unless a side wall of the projection rests tightly against a side wall of the groove over its entire length, air can enter the interior even with the doors closed flow of the refrigerator. The resulting high supply of heat and moisture makes the energy consumption of the refrigerator high.

Es ist daher wichtig, ein zweitüriges Kältegerät mit schwenkbarem Holm zu schaffen, das eine zuverlässige Abdichtung der Türen trotz eines Spiels in Längsrichtung des Holms ermöglicht.It is therefore important to provide a two-door refrigerator with a pivotable handlebar, which allows a reliable sealing of the doors despite a game in the longitudinal direction of the spar.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Kältegerät mit einem Korpus, mit einer ersten und einer zweiten Tür, die jeweils mit einer ihrer Kanten an entgegengesetzten Seiten einer Öffnung des Korpus angeschlagen sind, und mit einem Holm, der an eine Kante der ersten Tür angelenkt ist, die deren angeschlagener Kante gegenüber liegt, und der mit Hilfe eines Führungsvorsprungs, der in einer am Rand der Öffnung gebildeten Führungsnut verschiebbar ist, zwischen einer bei geschlossener erster Tür eingenommenen Stellung, in welcher eine Kante der zweiten Tür, die deren angeschlagener Kante gegenüber liegt, an dem Holm anliegt, und einer beim Öffnen der ersten Tür eingenommenen Stellung schwenkbar ist, in welcher der Holm in der Lage ist, die geschlossene zweite Tür zu passieren, der Führungsvorsprung in Bezug auf die erste Tür, in Richtung von deren Schwenkachse verschiebbar ist, der Führungsvorsprung in Bezug auf den Holm in Richtung der Schwenkachse der ersten Tür verschiebbar ist, wobei der im Querschnitt bogenförmige Führungsvorsprung in einem einen komplementären Querschnitt aufweisenden Kanal des Holms verschiebbar geführt ist. Dies ermöglicht es dem Führungsvorsprung, beim Schließen der ersten Tür, wenn nötig, in Richtung von deren Schwenkachse auszuweichen. Trotz eventueller Toleranzen der Aufhängung der Tür kann so sicher gestellt werden, dass keine Außenluft an dem Führungsvorsprung vorbei ins Innere des Kältegeräts gelangen kann.The object is achieved in that in a refrigerator with a body, with a first and a second door, which are each struck with one of its edges on opposite sides of an opening of the carcass, and with a spar which is connected to an edge of the first Door hinged, which lies opposite the chipped edge, and which is displaceable by means of a guide projection which is displaceable in a guide groove formed at the edge of the opening, between a closed door when the door is closed, in which an edge of the second door, their ailing Ridge is opposite, abuts the spar, and a position assumed when opening the first door position in which the spar is able to pass the closed second door, the guide projection with respect to the first door, in the direction of the latter Swivel axis is displaceable, the guide projection with respect to the spar in the direction of Schwenkachs e of the first door is displaceable, wherein the arcuate guide projection in cross-section is guided in a complementary cross-section channel of the spar slidably. This allows the guide projection, when closing the first door, if necessary, to deviate in the direction of its pivot axis. Despite possible tolerances of the suspension of the door can be made sure that no outside air can get past the guide projection into the interior of the refrigerator.

Im Allgemeinen wird man Führungsvorsprünge und Führungsnuten an beiden Längsenden des Holms bzw. diesen zugewandten Oberflächen des Korpus vorsehen. Bei wenigstens einem solchem Führungsvorsprung ist es möglich, dass dieser fest mit dem Holm verbunden ist und zusammen mit diesem in Richtung der Schwenkachse der Tür verschiebbar ist. Um jedoch die beim Einrücken des Holms in die Öffnung des Korpus zu verschiebende Masse klein zu halten, wird man im allgemeinen den Führungsvorsprung auch in Bezug auf den Holm in Richtung der Schwenkachse der ersten Tür verschiebbar machen.In general, one will provide guide projections and guide grooves on both longitudinal ends of the spar or these facing surfaces of the body. In at least one such guide projection, it is possible that it is firmly connected to the spar and together with this in the direction of the pivot axis of the door is displaceable. However, in order to keep small when moving the spar into the opening of the body to be reduced mass, you will make the guide projection in the direction of the pivot axis of the first door in general also with respect to the spar.

Die axiale Verschiebbarkeit des Führungsvorsprungs wird realisiert, indem der im Querschnitt bogenförmige Führungsvorsprung in einem einen komplementären Querschnitt aufweisenden Kanal des Holms verschiebbar geführt ist.The axial displaceability of the guide projection is realized by the guide in cross-section arcuate guide projection is guided in a complementary cross-section channel of the spar slidably.

Um das Einrücken des Holms in die Öffnung des Korpus zu erleichtern, ist vorzugsweise an einem beim Schließen der ersten Tür zuerst in die Führungsnut eingreifenden Bereich des Führungsvorsprungs eine Einführschräge gebildet, in welcher die - in Richtung der Schwenkachse gemessene - Höhe des Führungsvorsprungs zu dessen Ende hin abnimmt.In order to facilitate the engagement of the spar in the opening of the body, preferably at a closing of the first door engaging in the guide groove portion of the guide projection an insertion bevel is formed, in which - measured in the direction of the pivot axis - height of the guide projection to the end decreases.

Um eine Undichtigkeit an der Führungsnut zu vermeiden, sollte der Führungsvorsprung in der bei geschlossener erster Tür eingenommenen Stellung des Holms auf seiner gesamten Länge in die Führungsnut eintauchen.In order to avoid a leakage at the guide groove, the guide projection should dive in the position occupied by the closed first door position of the spar over its entire length in the guide groove.

Zur Abdichtung ist auch zweckmäßig, wenn die Führungsnut einen schrägen Bodenabschnitt aufweist, der die Einführschräge berührt, wenn sich der Holm in der bei geschlossener erster Tür eingenommenen Stellung befindet.For sealing is also expedient if the guide groove has an inclined bottom portion which contacts the insertion bevel when the spar is in the position assumed when the first door is closed.

Alternativ und/oder ergänzend zu einer Einführschräge des Führungsvorsprungs kann auch an der Führungsnut eine Einführschräge vorgesehen sein, in der die Tiefe der Nut zu einem offenen Ende derselben hin zunimmt.Alternatively and / or in addition to an insertion bevel of the guide projection, an insertion bevel may also be provided on the guide groove, in which the depth of the groove increases toward an open end thereof.

Der Führungsvorsprung ist vorzugsweise durch eine Feder in Richtung der Schwenkachse nach außen beaufschlagt.The guide projection is preferably acted upon by a spring in the direction of the pivot axis to the outside.

Fig. 1 ist eine perspektivische Ansicht eines Kältegeräts mit einem Korpus 1 und an Seitenwände 2, 3 des Korpus 1 angeschlagenen Türen 4, 5. Die linke Tür 4 ist in offener Stellung gezeigt, die rechte Tür 5 mit durchgezogenen Linien in offener und mit gestrichelten Linien in geschlossener Stellung. An die Innenseite der Tür 5 ist benachbart zu ihrer vom Türscharnier abgewandten Kante 6 ein Holm 7 um eine vertikale Achse 8 schwenkbar angelenkt. In der offenen Stellung der Tür 5 ist eine Schmalseite des im Querschnitt rechteckigen Holms 7 gegen die Innenseite der Tür 5 geschwenkt, so dass der Holm 7 seitlich nicht über die Kante 6 hinausragt. So kann der Holm 7 beim Schließen der Tür 5 die Tür 4 passieren, wenn diese geschlossen am Korpus 1 anliegt. Beim Schließen der Tür 5 rückt der Holm 7 ins Innere des Korpus ein und schwenkt dabei um die Achse 8, so dass eine Breitseite 9 von ihm in der Öffnung des Korpus 1 bündig mit dessen Rahmen 10 zu liegen kommt. In dieser Stellung bilden der Rahmen 10 und die Breitseite 9 eine bis auf schmale Spalte 11 zwischen den Enden des Holms 7 und dem Boden bzw. der Decke des Korpus 1 durchgehende Auflagefläche, an der sich Magnetdichtungen 12 der Türen 4, 5 dicht schließend anlegen. Die Breiten der Spalte 11 sind bemessen, um sicher zu stellen, dass beim Schließen der Tür der Holm 7 sicher in die Korpusöffnung einrücken kann, ohne dass seine Enden mit Boden oder Decke des Korpus kollidieren. Die hierfür erforderliche Breite kann je nach Stabilität des Korpus und der Türen und in Abhängigkeit davon, ob die Türen als Halter für (in der Fig. nicht gezeigte) Kühlgutträger genutzt werden, variieren. In der Praxis beträgt die Breite der Spalte 11 im allgemeinen einige wenige Millimeter. Fig. 1 is a perspective view of a refrigerator with a body 1 and hinged to side walls 2, 3 of the body 1 doors 4, 5. The left door 4 is shown in the open position, the right door 5 with solid lines in open and dashed lines in closed Position. On the inside of the door 5, a spar 7 is hinged about a vertical axis 8 adjacent to its edge facing away from the door hinge 6. In the open position of the door 5, a narrow side of the cross-sectionally rectangular spar 7 is pivoted against the inside of the door 5, so that the spar 7 does not protrude laterally beyond the edge 6. Thus, the spar 7 when closing the door 5, the door 4 happen when it rests closed on the body 1. When closing the door 5, the spar 7 moves into the interior of the body and pivots about the axis 8, so that a broad side 9 comes to rest from him in the opening of the body 1 flush with the frame 10. In this position, the frame 10 and the broad side 9 form a support surface, except for narrow gaps 11 between the ends of the spar 7 and the floor or the ceiling of the body 1, at which magnetic seals 12 of the doors 4, 5 create a tight seal. The widths of the column 11 are dimensioned to ensure that when closing the door, the spar 7 can safely engage in the carcass opening without its ends colliding with the floor or ceiling of the carcass. The width required for this can vary depending on the stability of the body and the doors and depending on whether the doors are used as holders for refrigerated goods carriers (not shown in the figure). In practice, the width of the column 11 is generally a few millimeters.

An den Enden des Holms 7 sind zwei Führungsvorsprünge 13 vertikal verschiebbar angebracht, wobei in der Perspektive der Fig. 1 nur der Führungsvorsprung 13 des oberen Endes zu sehen ist. Die Führungsvorsprünge 13 haben jeweils einen bogenförmigen Querschnitt, wobei die zwei Enden des Bogens mit der Breitseite 9 des Holms 7 abschließen. Die Höhe der Führungsvorsprünge 13 ist größer als die Breite der Spalte 11, so dass die Führungsvorsprünge 13 beim Schließen der Tür 5 an Decke und Boden des Korpus anstoßen.At the ends of the spar 7, two guide projections 13 are mounted vertically displaceable, wherein in the perspective of Fig. 1 only the guide projection 13 of the upper end can be seen. The guide projections 13 each have an arcuate cross section, wherein the two ends of the arc with the broad side 9 of the spar 7 complete. The height of the guide projections 13 is greater than the width of the Column 11, so that the guide projections 13 abut when closing the door 5 on the ceiling and bottom of the body.

Wie in Fig. 2 am Beispiel des oberen Führungsvorsprungs 13 gezeigt, sind die zwei Führungsvorsprünge 13 jeweils in einem Schlitz 14 des Holms 7 vertikal verschiebbar geführt. Genauer gesagt ist der Führungsvorsprung 13 fest mit einer Grundplatte 15 verbunden, und zwei am Holm 7 ortsfeste Stifte 16, von denen nur einer in Fig. 2 sichtbar ist, erstrecken sich durch Hülsen 32 an gegenüberliegenden Enden der Grundplatte 15. Durch Spiralfedern 17, die auf die Stifte 16 aufgesteckt und an einer umlaufenden Schulter 18 der Stifte 16 abgestützt sind, wird die Grundplatte 15 gegen eine Stirnwand 19 des Holms 7 gedrückt. Von der Stirnwand 19 rings um den Schlitz 14 ins Innere des Holms 7 abstehende Rippen 20 dienen einerseits zur Führung des Vorsprungs 13 in vertikaler Richtung und andererseits als Anschlag für dessen Grundplatte 15.As in Fig. 2 shown by the example of the upper guide projection 13, the two guide projections 13 are each guided vertically displaceably in a slot 14 of the spar 7. More specifically, the guide projection 13 is fixedly connected to a base plate 15, and two fixed to the spar 7 pins 16, of which only one in Fig. 2 is visible, extending through sleeves 32 at opposite ends of the base plate 15. By coil springs 17 which are plugged onto the pins 16 and supported on a circumferential shoulder 18 of the pins 16, the base plate 15 is pressed against an end wall 19 of the spar 7. From the end wall 19 around the slot 14 into the interior of the spar 7 protruding ribs 20 serve on the one hand to guide the projection 13 in the vertical direction and on the other hand as a stop for the base plate 15th

Beim Schließen der Tür 5 taucht das in Fig. 2 dem Betrachter zugewandte Ende 21 des Führungsvorsprungs 13 als erstes in die Öffnung des Korpus 1 ein. Die Höhe des Führungsvorsprungs 13 ist an dem Ende 21 minimal. Sie nimmt von dort aus entlang einer Einführschräge 22 allmählich zu, um dann auf einem Hauptabschnitt 23 des Führungsvorsprungs 13 konstant zu bleiben. Die Höhe des Führungsvorsprungs 13 ist auf seiner gesamten Länge größer als die Breite des Spalts 11, in den er beim Schließen der Tür 5 eindringt.When closing the door 5 dives in Fig. 2 the viewer facing end 21 of the guide projection 13 is the first in the opening of the body 1 a. The height of the guide projection 13 is minimal at the end 21. From there it gradually increases along an insertion bevel 22, in order to then remain constant on a main section 23 of the guide projection 13. The height of the guide projection 13 is greater over its entire length than the width of the gap 11, in which it penetrates when closing the door 5.

Die Konfiguration des nicht dargestellten unteren Führungsvorsprungs 13 ist zu derjenigen der Fig. 2 spiegelbildlich.The configuration of the lower guide projection 13, not shown, is similar to that of FIG Fig. 2 mirror image.

Fig. 3 zeigt aus der gleichen Blickrichtung wie in Fig. 1 einen Ausschnitt des Bodens des Korpus 1. Der Boden ist durch eine aus Kunststoff tiefgezogene Platte 24 gebildet, in der eine flache Nische geformt ist, die einen Führungsblock 25 aufnimmt. An der Oberseite des Führungsblocks 25 verläuft eine komplementär zum Führungsvorsprung 13 gekrümmte Führungsnut 26. Die Führungsnut 26 hat eine trichterartig aufgeweitete Eingangsöffnung 27, die auf die Vorderseite des Führungsblocks 25 mündet und in die beim Schließen der Tür 5 der Führungsvorsprung 13 mit seinem Ende 21 voran einrückt. Ein der Eingangsöffnung 27 gegenüberliegendes Ende 28 der Führungsnut 26 mündet ebenfalls auf die Vorderseite des Blocks 25. Fig. 3 shows from the same direction as in Fig. 1 a bottom of the body of the body 1. The bottom is formed by a plastic deep-drawn plate 24 in which a flat niche is formed, which receives a guide block 25. The guide groove 26 has a funnel-like widened entrance opening 27, which opens onto the front of the guide block 25 and in the closing of the door 5 of the guide projection 13 with its end 21 in front engages. One of the input opening 27 opposite end 28 of the guide groove 26 also opens to the front of the block 25th

Die Fig. 4 bis 6 veranschaulichen an Hand von schematischen Schnitten den Schließvorgang der Tür 5. In diesen Figuren sind die Türen 4, 5 und mit ihnen bewegliche Teile jeweils gestrichelt dargestellt, während der ortsfeste Führungsblock 25 durchgezogen gezeichnet ist. Die folgende Beschreibung erfolgt im Hinblick auf den unteren Führungskörper 25 und den darin einrückenden Führungsvorsprung 13, wobei sich versteht, dass spiegelsymmetrisch gleiche Verhältnisse am oberen Führungskörper 25 vorliegen.The 4 to 6 illustrate on the basis of schematic sections, the closing operation of the door 5. In these figures, the doors 4, 5 and moving parts are each shown in dashed lines, while the fixed guide block 25 is drawn through. The following description is made with regard to the lower guide body 25 and the guide projection 13 engaging therein, it being understood that mirror-symmetrical conditions are present on the upper guide body 25.

Fig. 4 zeigt ein Stadium der Schließbewegung der Tür 5, in welchem der Holm 7 mit einer Schmalseite an der Innenseite der Tür 5 anliegt, und die von der Tür 5 abgewandte Einführschräge 22 des Führungsvorsprungs 13 beginnt, in die Eingangsöffnung 27 des Führungsblocks 25 einzurücken und eine konvexe Seitenflanke 29 des Führungsvorsprungs 13 beginnt, eine dem Korpusinneren zugewandte Seitenwand 30 der Führungsnut 26 zu berühren. Fig. 4 shows a stage of the closing movement of the door 5, in which the spar 7 abuts with a narrow side on the inside of the door 5, and facing away from the door 5 insertion bevel 22 of the guide projection 13 begins to engage in the inlet opening 27 of the guide block 25 and a convex Side edge 29 of the guide projection 13 begins to touch a body interior facing the side wall 30 of the guide groove 26.

Beim weiteren Schließen der Tür 5 gleitet die Seitenflanke 29 an der Wand 30 entlang, wodurch der Holm 7 geschwenkt wird. Gleichzeitig berührt kurz vor oder hinter dem Stadium der Fig. 4 die Einführschräge 22 den Boden der Führungsnut 26 an deren Eingangsöffnung 27, so dass bei Fortsetzung der Schließbewegung der Führungsvorsprung 13 nach oben und in den Holm 7 hinein zurück gedrängt wird. Die Verdrängung des Führungsvorsprungs 13 nach oben endet, sobald die Einführschräge 22 den Eingang der Führungsnut 26 passiert hat und der gleichbleibend hohe Hauptabschnitt 23 auf dem Boden der Nut 26 gleitet.Upon further closing of the door 5, the side edge 29 slides along the wall 30, whereby the spar 7 is pivoted. At the same time, shortly before or after the stage touches the Fig. 4 the insertion bevel 22 the bottom of the guide groove 26 at the inlet opening 27, so that upon continuation of the closing movement of the guide projection 13 is pushed back upwards and into the spar 7 in. The displacement of the guide projection 13 upwards ends as soon as the insertion bevel 22 has passed the entrance of the guide groove 26 and the consistently high main section 23 slides on the bottom of the groove 26.

Im Stadion der Fig. 5 ist der Führungsvorsprung 13 auf einem großen Teil seiner Länge in die Nut 26 eingerückt.In the stadium of the Fig. 5 the guide projection 13 is engaged in the groove 26 over a large part of its length.

Bei vollständig geschlossener Tür 5, wie in Fig. 6 gezeigt, befindet sich das führende Ende 21 des Führungsvorsprungs 13 am Ende 28 der Führungsnut 26 und schließt bündig mit der Vorderseite des Führungsblocks 25 ab. Die Einführschräge 22 des Führungsvorsprungs 13 liegt auf einem schrägen Abschnitt 31 des Bodens der Nut 26 auf. Der Führungsvorsprung 13 berührt den Boden der Nut 26 auf deren gesamter Länge und blockiert somit den Spalt 11 luftdicht, ohne dass die Seitenflanken der Führungsvorsprungs 13 zwischen den Wänden der Nut 26 geklemmt sein und eine der Seitenflanken auf ihrer ganzen Länge an einer Seitenwand der Nut 26 anliegen müsste. Somit kann der beim Einführen des Führungsvorsprungs 13 in die Führungsnut 26 zu überwindende Reibungswiderstand gering gehalten werden, und die Endstellung der Fig. 6, in welcher das führende Ende 21 des Führungsvorsprungs 13 mit der Vorderseite des Führungsblocks 25 bündig ist, wird zuverlässig erreicht. So wird eine ebene Anlagefläche geschaffen, die sich vom Rahmen über das den Spalt 11 überbrückende Ende 21 des Führungsvorsprungs bis auf den Holm 7 erstreckt und an der die Magnetdichtung 12 der Tür 4 dicht anschließen kann.With the door 5 completely closed, as in Fig. 6 shown, the leading end 21 of the guide projection 13 at the end 28 of the guide groove 26 and terminates flush with the front of the guide block 25 from. The insertion bevel 22 of the guide projection 13 rests on an inclined portion 31 of the bottom of the groove 26. The guide projection 13 contacts the bottom of the groove 26 over its entire length and thus blocks the gap 11 airtight, without the side edges of the guide projection 13 may be clamped between the walls of the groove 26 and one of Side edges on its entire length on a side wall of the groove 26 would have to rest. Thus, the frictional resistance to be overcome when inserting the guide projection 13 into the guide groove 26 can be kept low, and the end position of the Fig. 6 in which the leading end 21 of the guide projection 13 is flush with the front of the guide block 25 is achieved reliably. Thus, a flat bearing surface is provided which extends from the frame over the gap 11 bridging end 21 of the guide projection to the spar 7 and to which the magnetic seal 12 of the door 4 can connect tightly.
