Description

Tür für ein Kältegerät Door for a refrigeration appliance
Die vorliegende Erfindung betrifft eine Tür für ein Kältegerät. Eine solche Tür umfasst herkömmlicherweise steife Innen- und Außenwände, die an ihren Rändern miteinander verbunden sind, um einen Hohlraum zu begrenzen, der mit einem Schaumstoffmaterial ausgefüllt wird, um eine Isolationsschicht zu bilden. Die Außenwand ist bei einem freistehenden Kältegerät üblicherweise ein lackiertes Blech, das die Vorderseite und zwei Seitenflanken des Türblatts bildet. Auch obere und untere Flanken des Türblatts können durch Abwinkein des Blechs gebildet sein. Auf diese Weise kann eine völlig plane, ebenmäßige Vorderseite erhalten werden, aber es ist aufwändig, die aneinander stoßenden Ränder der seitlichen, oberen und unteren Flanken dicht und optisch ansprechend miteinander zu verbinden. Eine verbreitetere Bauweise ist daher, durch die Außenwand lediglich Vorderseite und seitliche Flanken des Türblatts zu bilden, diese an ihren vertikalen Rändern mit der Innenwand zu verbinden und eine obere und untere Öffnung des von Innen- und Außenwand begrenzten Hohlraums jeweils mit Hilfe eines aus Kunststoff geformten Abschlussteils zu verschließen. Ein solches Abschlussteil hat jeweils eine Grundplatte, die die Öffnung überdeckt, einen Steg, der am Rand der Grundplatte entlang absteht und an dessen Innenseite die Außenwand anliegt. Eine solche Tür hat keine glatte Vorderseite, da der Steg über den Außenrand vorsteht.The present invention relates to a door for a refrigeration appliance. Such a door conventionally includes rigid inner and outer walls joined together at their edges to define a cavity which is filled with a foam material to form an insulating layer. The outer wall is in a free-standing refrigeration device usually a painted sheet, which forms the front and two side edges of the door leaf. Also upper and lower flanks of the door leaf can be formed by bending the sheet. In this way, a completely flat, even front can be obtained, but it is costly to connect the abutting edges of the lateral, upper and lower edges dense and visually appealing. Therefore, a more common construction is to form only the front side and side flanks of the door panel by the outer wall, to connect them at their vertical edges to the inner wall and an upper and lower opening of the inner and outer wall bounded cavity each with the aid of a molded plastic Close the end part. Such a closure part in each case has a base plate which covers the opening, a web which projects along the edge of the base plate and on the inside of which the outer wall rests. Such a door has no smooth front, since the bridge protrudes beyond the outer edge.
Aufgabe der Erfindung ist, eine Tür für ein Kältegerät anzugeben, die einen einfachen, preiswert realisierbaren Aufbau hat und dennoch geeignet ist, Vorsprünge und Unebenheiten an der Vorderseite der Tür zu vermeiden.The object of the invention is to provide a door for a refrigeration device, which has a simple, inexpensive realizable structure and yet is suitable to avoid projections and bumps on the front of the door.
Die Aufgabe wird gelöst durch eine Tür mit einer Außenwand und einer Innenwand, die einen Hohlraum seitlich umgeben, und wenigstens einem Abschlussteil, das eine vonThe object is achieved by a door with an outer wall and an inner wall which laterally surround a cavity, and at least one end part, which is one of
Außenwand und Innenwand begrenzte obere oder untere Öffnung des Hohlraums verschließt und eine Grundplatte und einen sich entlang eines Randes der Grundplatte erstreckenden Steg aufweist, bei der die Außenwand einen Mittelbereich und einen gegenüber dem Mittelbereich gekröpften Randbereich aufweist, der an einer Innenseite des Stegs anliegt, während eine Außenseite des Stegs mit dem Mittelbereich bündig ist. Um die Außenwand in Bezug auf den Steg zu fixieren, kann der gekröpfte Randbereich wenigstens stellenweise in einer Nut aufgenommen sein, die an einer Seite durch den Steg begrenzt ist.Outer wall and inner wall closes limited upper or lower opening of the cavity and has a base plate and a web extending along an edge of the base plate, wherein the outer wall has a central region and a relation to the central region cranked edge region which abuts an inner side of the web during an outer side of the web is flush with the central region. In order to fix the outer wall with respect to the web, the cranked edge region may at least in places be received in a groove bounded on one side by the web.
An ihrer dem Steg gegenüberliegenden Seite ist die Nut vorzugsweise durch einen die Kröpfung der Außenwand umgreifenden Arm begrenzt. Ein solcher Arm verriegelt das Abschlussteil und die Außenwand aneinander und sorgt so für einen inneren Zusammenhalt der Tür unabhängig von einer in dem Hohlraum aufgenommenen Isoliermaterialfüllung.On its side opposite the web, the groove is preferably delimited by an arm that encompasses the offset of the outer wall. Such an arm locks the end portion and the outer wall together and thus provides internal cohesion of the door independently of an insulative material fill received in the cavity.
An dem Abschlussteil kann, insbesondere wenn es die obere Öffnung des Hohlraums verschließt, eine Aussparung gebildet sein, in der ein Scharnier der Tür verborgen ist.At the terminal part, in particular when it closes the upper opening of the cavity, a recess may be formed in which a hinge of the door is concealed.

Von den zwei Bohrungen 19 des Endabschnitts 12 liegt eine einer kreisrunden Öffnung 21 und die andere dem Schlitz 15 des Endabschnitts 13 gegenüber. Durch die Öffnung 21 bzw. den Schlitz 15 hindurch können jeweils die einzelnen Schrauben in die Bohrungen 19 und die Gewindelöcher 18 eingeführt werden. Zum Befestigen der Schrauben kann auch ein Schraubenzieher oder dgl. die Öffnung 21 bzw. den Schlitz 15 passieren.Of the two holes 19 of the end portion 12 is one of a circular opening 21 and the other the slot 15 of the end portion 13 opposite. Through the opening 21 and the slot 15 through each of the individual screws in the holes 19 and the threaded holes 18 are introduced. To fasten the screws, a screwdriver or the like can also pass through the opening 21 or the slot 15.
In Höhe der Winkel 11 sind zur Versteifung jeweils zwei Sicken 20 in den Arm 10 geprägt.In height of the angle 11 two beads 20 are embossed in the arm 10 for stiffening.
Ein zum Einführen in die Hülse 16 vorgesehener Scharnierbolzen ist mit 22 bezeichnet. Der Scharnierbolzen hat die Form eines zylindrischen Stifts, der durch einen umlaufenden Steg 23 in einen in die Hülse 16 eingreifenden oberen Abschnitt 24 und einen unteren Abschnitt 25 gegliedert ist. Bei dem hier betrachteten Ausführungsbeispiel ist der obere Abschnitt 24 drehfest in den Hülsen 16 aufgenommen, und der untere Abschnitt 25 greift drehbar in eine (nicht dargestellte) Scharnierhülse der Tür 2 ein. Denkbar wäre aber auch, den Scharnierbolzen 22 in der Tür drehfest zu verankern und in den Hülsen 16 drehbar zu machen, oder eine Drehbarkeit des Scharnierbolzens 22 sowohl gegenüber dem Arm 10 als auch der Tür 2 zuzulassen.A provided for insertion into the sleeve 16 hinge pin is designated 22. The hinge pin is in the form of a cylindrical pin, which is divided by a circumferential ridge 23 in an engaging in the sleeve 16 upper portion 24 and a lower portion 25. In the embodiment considered here, the upper portion 24 is rotatably received in the sleeves 16, and the lower portion 25 rotatably engages in a (not shown), a hinge sleeve of the door 2 a. It would also be conceivable, however, to anchor the hinge pin 22 in the door in a rotationally fixed manner and to turn it in the sleeves 16, or to allow a rotation of the hinge pin 22 both relative to the arm 10 and the door 2.
Fig. 5 zeigt einen horizontalen Schnitt durch die obere rechte Ecke des Korpus 1 und der Tür 2 in Höhe des Arms 10. Das Abschlussstück 5 weist an seiner dem Rahmen 9 zugewandten Rückseite eine geräumige Aussparung 26 auf, in die der Arm 10 eingreift. Der Arm 10 begrenzt eine Ausnehmung 27, die zu der Seitenfläche 4 hin offen ist. Eine Seitenwand 28 des Abschlussstücks 5 verläuft vor der Ausnehmung 27 her und ist im wesentlichen bündig mit der Seitenfläche 4.Fig. 5 shows a horizontal section through the upper right corner of the body 1 and the door 2 at the level of the arm 10. The end piece 5 has on its the frame 9 facing the rear side a spacious recess 26, in which the arm 10 engages. The arm 10 defines a recess 27 which is open to the side surface 4. A side wall 28 of the end piece 5 extends in front of the recess 27 and is substantially flush with the side surface 4th
Der Abstand zwischen dem vorderen Rahmen 9 und dem ihm zugewandten Ende 29 der Seitenwand 28 ist so gewählt, dass, wenn die Tür 2 um die von dem Scharnierbolzen 22 definierte Achse in die in Fig. 6 gezeigte Stellung aufgeschwenkt wird, auf seiner durch einen Pfeil 30 bezeichneten Bahn soeben nicht den Rahmen 9 berührt. In der aufgeschwenkten Stellung greift die Seitenwand 28 tief in die Ausnehmung 27 des Arms ein. Maximale Öffnungswinkel der Tür von weit über 90 Grad sind mit der in den Fig. gezeigten Geometrie ohne weiteres erreichbar. Noch größere Öffnungswinkel sind realisierbar, wenn der Endabschnitt 13 nicht geradlinig, wie in den Figuren gezeigt, sondern nach vorn gewölbt ausgeführt ist.The distance between the front frame 9 and the end 29 facing it of the side wall 28 is selected so that when the door 2 is pivoted about the axis defined by the hinge pin 22 in the position shown in Fig. 6, on its by an arrow 30 designated track just does not touch the frame 9. In the swung-open position, the side wall 28 engages deeply into the recess 27 of the arm. Maximum opening angles of the door of well over 90 degrees are readily achievable with the geometry shown in the figures. Even larger opening angles can be realized if the end section 13 is not rectilinear, as shown in the figures, but is curved toward the front.
Fig. 7 zeigt einen vertikalen Schnitt durch den oberen Bereich der Tür 2 in Höhe der Linie VII-VII aus Fig. 6. Das Abschlussstück 5 ist hier aus zwei Formteilen, einem unteren Teil 31 und einem oberen Teil 32 zusammengefügt. Das obere Teil 32 ist im wesentlichen plattenförmig mit an seiner Unterseite abstehenden Verankerungsstiften 33, die reibschlüssig in Sacklöcher 34 des unteren Teils 31 eingreifen. Das untere Teil 31 hat eine Grundplatte 38, die den Hohlraum 35 des Mittelstücks 7 abschließt.Fig. 7 shows a vertical section through the upper portion of the door 2 at the level of the line VII-VII of Fig. 6. The end piece 5 is here of two mold parts, a lower part 31 and an upper part 32 joined together. The upper part 32 is substantially plate-shaped with protruding on its underside anchoring pins 33 which engage frictionally engaged in blind holes 34 of the lower part 31. The lower part 31 has a base plate 38 which closes the cavity 35 of the middle piece 7.
Rings um den Rand der Grundplatte 38 erstreckt sich ein nach unten abstehender Steg 39. An der Innenseite des Stegs 39 liegen ein oberer Rand der Innenwand 37 sowie der obere Randbereich 44 der Außenwand 36 an. Die Kröpfung zwischen den zwei Randbereichen 44 und dem Mittelbereich 43 der Außenwand 36 ist entsprechend der Dicke des Stegs 39 gewählt, so dass die Außenfläche des Stegs 39 bündig an den Mittelbereich 43 der Außenwand anschließt. So wird eine auf ihrer gesamten Höhe stufenlos glatte Außenfläche der Tür 2 erhalten.An upwardly projecting web 39 extends around the edge of the base plate 38. An upper edge of the inner wall 37 and the upper edge region 44 of the outer wall 36 rest on the inner side of the web 39. The offset between the two edge regions 44 and the central region 43 of the outer wall 36 is selected according to the thickness of the web 39, so that the outer surface of the web 39 is flush with the central region 43 of the outer wall. Thus, an infinitely smooth outer surface of the door 2 is obtained over its entire height.
Eine Scharnierhülse 40, die den unteren Abschnitt 25 des Scharnierbolzens 22 aufnimmt, ist einteilig in der Grundplatte 38 ausgeformt und greift in den Hohlraum 35 des Mittelstücks 7 ein.A hinge sleeve 40, which receives the lower portion 25 of the hinge pin 22, is integrally formed in the base plate 38 and engages in the cavity 35 of the center piece 7 a.
Die Aussparung 26 erstreckt sich über die gesamte Breite der Tür, von der einen Seitenwand 28 des Abschlussstücks 5 zur spiegelsymmetrisch gegenüberliegenden. Benachbart zu dieser gegenüberliegenden Seitenwand ist eine zweite, nicht gezeigte Scharnierhülse 40 ausgeformt, um einen Anschlagwechsel der Tür zu ermöglichen.The recess 26 extends over the entire width of the door, from the one side wall 28 of the end piece 5 to the mirror-symmetrically opposite. Adjacent to this opposite side wall, a second, not shown, hinge sleeve 40 is formed to allow a stop change of the door.
Das nicht eigens in einem Schnitt dargestellte untere Abschlussteil 6 hat spiegelsymmetrisch zu dem unteren Teil 31 eine Grundplatte, die den Hohlraum 35 des Mittelstücks abschließt, einen am Rand der Grundplatte umlaufenden Steg, an dem Außen- und Innenwand 36, 37 anliegen, und eine Scharnierhülse, die einen von unten her eingreifenden Scharnierbolzen aufnimmt. Die Außenseite der Grundplatte ist beim unteren Abschlussteil 6 eben.The lower end part 6, which is not specifically shown in a section, has mirror-symmetrical to the lower part 31 a base plate which closes off the cavity 35 of the center piece, a web surrounding the edge of the base plate, against the outer and inner walls 36, 37, and a hinge sleeve , which receives a bottom engaging hinge pin. The outside of the base plate is flat at the lower end part 6.
Bei der Ausgestaltung der Fig. 7 besteht kein formschlüssiger Eingriff zwischen den oberen und unteren Rändern der Wände 36, 37 und den Abschlussteilen 5, 6. Es ist daher nicht ausgeschlossen, dass, wenn die Abschlussteile 5, 6 auf die zusammengefügten Wände 36, 37 aufgesteckt werden, die Außenwand 36 stellenweise hinter die Außenseite des Stegs 39 eines der Abschlussteile 5, 6 zurückspringt. Sobald jedoch der Hohlraum 35 mit Isolierschaum ausgefüllt wird, drückt er die Wände 36, 37 nach außen, so dass ein bündiger Übergang zwischen dem Steg 39 und der Außenwand 36 erhalten wird.In the embodiment of Fig. 7 there is no positive engagement between the upper and lower edges of the walls 36, 37 and the closure parts 5, 6. It is therefore not excluded that when the closure parts 5, 6 on the joined walls 36, 37 be plugged, the outer wall 36 in places behind the outside of the web 39 of one of the end parts 5, 6 springs back. However, as soon as the Cavity 35 is filled with insulating foam, it presses the walls 36, 37 to the outside, so that a flush transition between the web 39 and the outer wall 36 is obtained.
Bei einer alternativen Ausgestaltung, die in Fig. 8 in einem zu Fig. 7 analogen Schnitt dargestellt ist, ist an der Grundplatte 38 jedes Abschlussteils 5, 6 ein weiterer Steg 45 gebildet, der zusammen mit dem äußeren Steg 39 eine Nut begrenzt, in die der obere bzw. untere Randbereich 44 der Außenwand 36 und die Ränder der Innenwand 37 formschlüssig eingreifen. Um die Einführung der Wände 36, 37 in diese Nut zu vereinfachen, kann die Scheitelfläche des Stegs 45 mit einer Fase 46 versehen sein.In an alternative embodiment, which is shown in FIG. 8 in a section similar to FIG. 7, a further web 45 is formed on the base plate 38 of each end part 5, 6, which together with the outer web 39 defines a groove into which the upper or lower edge region 44 of the outer wall 36 and the edges of the inner wall 37 engage in a form-fitting manner. In order to facilitate the insertion of the walls 36, 37 in this groove, the apex surface of the web 45 may be provided with a chamfer 46.
An dem zur Außenwand 36 benachbarten Teil des Stegs 45 können ferner einzelne elastisch biegsame Rastarme 47 vorgesehen sein, die beim Einführen des Randbereichs 44 der Außenwand 36 in die Nut zwischen den Stegen 39, 45 elastisch nach innen zurückweichen und die, wenn der Randbereich 44 vollständig in die Nut eingeführt ist, die Kröpfung zwischen Randbereich 44 und Mittelbereich 43 der Außenwand 36 hintergreifen. Auf diese Weise ist für einen von Anfang an dichten Anschluss des Randbereichs 44 an den äußeren Steg 39 und für einen zumindest provisorischen Zusammenhalt des Mittelstücks 7 mit den Abschlussteilen 5, 6 noch vor dem Ausfüllen mit Isolierschaum gesorgt. On the outer wall 36 adjacent part of the web 45 may also be provided individually elastically flexible latching arms 47, which yield elastically inwardly upon insertion of the edge portion 44 of the outer wall 36 in the groove between the webs 39, 45 and when the edge portion 44 completely is introduced into the groove, the crank between the edge region 44 and the central region 43 of the outer wall 36 engage behind. In this way, provision is made for an initially tight connection of the edge region 44 to the outer web 39 and for at least provisional cohesion of the middle piece 7 with the end parts 5, 6 even before filling with insulating foam.
