Abstract

The invention relates to a refrigerating device comprising a heat-insulating housing (2) which can be closed by a door (1). Said door (1) comprises a door leaf (3), a circumferential sealing strip (4) situated on an inner surface of the door leaf (3) and used for sealing the door to a frame (5) of the housing, and a handle (12) which is mounted on the door leaf (3) in a moveable manner. An active arm (7) which is connected to the handle (12) enables contact to be made in a first position between the sealing strip (4) and the frame (5), and protrudes against said frame (5) in a second position to avoid making said contact. The door leaf (3) can optionally be mounted on the housing in such a way that it can rotate about one of two axes in the region of its vertical edges. The handle (12) and the active arm (7) are embodied in two parts and can be connected to each other in two mirror-image configurations.

Description

Kältegerät mit Türöffnungshilfe Refrigerator with door opening aid
Die Erfindung betrifft ein Kältegerät mit einem durch eine Tür verschließbaren wärmeisolierenden Gehäuse, wobei die Tür ein Türblatt, einen an einer Innenfläche des Türblatts umlaufenden Dichtstreifen zum Abdichten der Tür an einem Rahmen des Gehäuses und einen am Türblatt beweglich montierten Griff aufweist, wobei ein mit dem Griff verbundener Wirkarm in einer ersten Stellung einen Kontakt zwischen dem Dichtstreifen und demThe invention relates to a refrigerator with a heat-insulated housing that can be closed by a door, the door having a door leaf, a circumferential sealing strip on an inner surface of the door leaf for sealing the door on a frame of the housing and a handle movably mounted on the door leaf, one with the Handle connected active arm in a first position, a contact between the sealing strip and the
Rahmen zulässt und in einer zweiten Stellung vom Türblatt so weit gegen den Rahmen vorsteht, dass er den Kontakt verhindert. Ein solches Kältegerät ist aus DE 196 52 828 A1 bekannt.Allows the frame and in a second position protrudes from the door leaf so far against the frame that it prevents contact. Such a refrigerator is known from DE 196 52 828 A1.
Zweck dieses Wirkarms ist, das Öffnen der Tür zu erleichtern. Insbesondere wenn die Tür eines Tür eines Kältegeräts kurz nachdem sie geschlossen worden ist, erneut geöffnet werden muss, herrscht aufgrund der Abkühlung von im offenen Zustand in den Innenraum des Kältegeräts eingedrungener Warmluft in diesem einen Unterdruck, so dass zum Öffnen der Tür ein erheblicher Widerstand zu überwinden sein kann. Dieser Widerstand kann so groß sein, dass bei unachtsamer Handhabung die Standfestigkeit eines mit nur wenig Kühlgut gefüllten Kältegeräts beeinträchtigt sein kann.The purpose of this arm is to make opening the door easier. In particular, if the door of a door of a refrigeration device has to be opened again shortly after it has been closed, there is a negative pressure in the interior of the refrigeration device due to the cooling of open air, so that there is considerable resistance to opening the door can be overcome. This resistance can be so great that the carelessness of a refrigerator filled with only a few refrigerated items can be impaired if it is handled carelessly.
Der Wirkarm erleichtert das Öffnen der Tür dadurch, dass er durch Betätigen des Griffs aus seiner ersten Stellung in die über den Dichtstreifen vorstehende zweite Stellung bringbar ist, in der er die Tür vom Rahmen des Kältegeräts abspreizt. Durch den so entstehenden Spalt zwischen dem Rahmen und dem Lichtstreifen kommt ein Druckausgleich zustande, so dass anschließend die Tür ohne nennenswerten Widerstand zu öffnen ist.The active arm facilitates the opening of the door in that it can be moved from its first position into the second position protruding beyond the sealing strip by actuating the handle, in which it spreads the door from the frame of the refrigerator. The gap between the frame and the light strip creates a pressure equalization, so that the door can then be opened without any significant resistance.
Die Mehrzahl der gegenwärtig kommerziell verfügbaren Modelle von Kältegeräten haben Türen, die jeweils nach Gutdünken des Anwenders mit einer Schwenkachse im Bereich ihres linken oder rechten Randes an dem Gehäuse montierbar sind. Eine solche Konstruktion ist für den Hersteller wirtschaftlich, weil sie eine einheitliche Fertigung erlaubt und die Teilevielfalt reduziert, und weil die Lage der Schwenkachse erst festgelegt werden muss, wenn das Gerät beim Anwender aufgestellt wird, wofür meist ohnehin ein Kunden- dienstmitarbeiter beim Anwender anwesend sein muss, der diese Festlegung miterledigen kann.The majority of models of refrigeration devices currently commercially available have doors which can be mounted on the housing at the user's discretion with a pivot axis in the region of their left or right edge. Such a construction is economical for the manufacturer because it allows uniform production and reduces the number of parts, and because the position of the swivel axis only has to be determined when the device is set up by the user, for which a customer usually service employee must be present at the user, who can help with this determination.
Ein Nachteil der aus DE 196 52 828 A1 bekannten Konstruktion ist jedoch, dass sie sei- jtenspezifisch ist. Das heißt, ein Griff und ein Wirkarm der bekannten Konstruktion, die z.B. zur Anbringung an der rechten unteren Ecke einer Tür vorgesehen sind, die um eine im Bereich ihrer linken Kante verlaufende Achse schwenkbar ist, können nicht an der linken unteren Ecke montiert werden, falls eine Schwenkbarkeit der Tür um eine Achse im Bereich des rechten Randes erwünscht ist. Dies zwingt den Hersteller dazu, zwei verschiedene Modelle von Türen, jeweils mit rechter bzw. linker Schwenkachse, mit dazu passen- dem Griff und Wirkarm herzustellen, und der Benutzer eines solchen Geräts muss sich beim Kauf für eine der zwei Varianten entscheiden.A disadvantage of the construction known from DE 196 52 828 A1 is, however, that it is site-specific. That is, a handle and an active arm of the known construction, which e.g. are intended for attachment to the lower right corner of a door which can be pivoted about an axis running in the area of its left edge, cannot be mounted on the lower left corner if pivoting of the door about an axis in the area of the right edge is desired , This forces the manufacturer to produce two different models of doors, each with a right or left pivot axis, with a matching handle and active arm, and the user of such a device has to choose one of the two variants when buying it.
Aufgabe der vorliegenden Erfindung ist, das oben beschriebene, aus DE 196 52 828 A1 beschriebene Kältegerät dahingehend weiter zu entwickeln, dass die Tür nach Wahl mit rechter oder linker Schwenkachse montiert werden kann, ohne dass dafür das Türblatt, der Griff oder der Wirkarm ausgetauscht werden müssen.The object of the present invention is to further develop the refrigeration device described above from DE 196 52 828 A1 in such a way that the door can be mounted with a right or left pivot axis as desired, without the door leaf, the handle or the active arm being replaced have to.
Diese Aufgabe wird durch ein Kältegerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a refrigeration device with the features of claim 1.
Dabei dient zum Verbinden von Griff und Wirkarm vorzugsweise ein Stift, der quer zu zwei im wesentlichen parallelen, von einander beabstandeten Ebenen orientiert ist, in denen sich Griff und Wirkarm erstrecken. Zweckmäßigerweise ist die Bewegung des Griffs und des Wirkarms eine Schwenkbewegung, wobei der Stift gleichzeitig eine Schwenkachse für diese Bewegung bildet.To connect the handle and the active arm, a pin is preferably used, which is oriented transversely to two essentially parallel, spaced apart planes, in which the handle and the active arm extend. The movement of the handle and the active arm is expediently a pivoting movement, the pin simultaneously forming a pivot axis for this movement.
Eine besonders einfache Montage des Griffs und des Wirkarms an der Tür wird dadurch ermöglicht, dass der Stift mit dem Wirkarm einstückig ausgebildet ist. In diesem Fall kann nämlich an der Frontfläche des Türblatts zur Einführung des Griffs ein einfacher Schlitz ausgebildet sein, und an einer dem Schlitz benachbarten Seitenfläche des Türblatts ist eine Öffnung ausgebildet, durch die der Wirkarm einführbar und mit dem Verbindungsabschnitt des Griffs drehfest über den Stift verbindbar ist. Um nach der Montage des Wirkarms die Öffnung zu verdecken, ist zweckmäßigerweise eine Kappe vorgesehen.A particularly simple assembly of the handle and the active arm on the door is made possible in that the pin is formed in one piece with the active arm. In this case, namely, a simple slot can be formed on the front surface of the door leaf for introducing the handle, and an opening is formed on a side surface of the door leaf adjacent to the slot, through which the active arm can be inserted and connected to the connecting portion of the handle in a rotationally fixed manner via the pin is. In order to cover the opening after the assembly of the active arm, a cap is expediently provided.
Diese Kappe kann ein Lagerelement für den Stift aufweisen, um die Achse der Schwenkbewegung zu stabilisieren.This cap can have a bearing element for the pin in order to stabilize the axis of the pivoting movement.
Für die Anbringung des Stifts und des Wirkarms an dem Türblatt in zwei spiegelbildlichen Konfigurationen können insgesamt zwei Schlitze jeweils zu der gleichen Seitenfläche benachbart und spiegelsymmetrisch zu einander angeordnet sein. Diese Variante ist besonders zweckmäßig, wenn die Seitenfläche eine horizontale Seitenfläche ist, d.h. wenn der Griff in der Nähe der oberen oder unteren Kante des Türblatts angeordnet ist, um einen großen Abstand des Griffs von der Schwenkachse der Tür und damit einen großen Hebelarm gewährleisten zu können. Falls der Griff an der jeweils der Schwenkachse gegenüberliegenden vertikalen Kante des Türblatts angebracht wird, kann ein Schlitz ausreichen.For the attachment of the pin and the active arm to the door leaf in two mirror-image configurations, a total of two slots can each be arranged adjacent to the same side surface and mirror-symmetrically to one another. This variant is particularly useful if the side surface is a horizontal side surface, i.e. if the handle is arranged near the upper or lower edge of the door leaf in order to ensure a large distance of the handle from the pivot axis of the door and thus a large lever arm. If the handle is attached to the vertical edge of the door leaf opposite the pivot axis, a slot may be sufficient.
Falls zwei Schlitze vorgesehen werden, kann die Kappe durch ein Profilelement zum Abdecken beider Öffnungen und des jeweils freien Schlitzes ersetzt sein.If two slots are provided, the cap can be replaced by a profile element for covering both openings and the respective free slot.
Um mit dem Wirkarm eine große Kraft übertragen zu können, ist dieser zweckmäßiger- weise im wesentlichen plattenförmig ausgebildet, wobei seine mit dem Rahmen zusammenwirkende Spitze verdickt ist, um die auf den Rahmen beim Öffnen ausgeübte Kraft auf eine große Fläche zu verteilen und so Abrieb zu begrenzen.In order to be able to transmit a large force with the active arm, the latter is expediently essentially plate-shaped, its tip cooperating with the frame being thickened in order to distribute the force exerted on the frame upon opening over a large area and thus to abrasion limit.

Fig. 1 zeigt eine Draufsicht auf eine Tür 1 und den daran angrenzenden Bereich des Gehäuses 2 eines Kältegeräts im Bereich der rechten oberen Ecke der Tür 1. Die Tür 1 um- fasst ein hohles, mit einem wärmedämmenden Schaummaterial ausgefülltes Türblatt 3, an dessen Innenfläche ein elastischer Dichtstreifen 4 angebracht ist. In der in der Fig. gezeigten geschlossenen Stellung der Tür liegt der Dichtstreifen 4 am Rahmen 5 des Gehäuses 2 an, so dass der Innenraum des Kältegeräts nahezu luftdicht verschlossen ist.1 shows a plan view of a door 1 and the region of the housing 2 of a refrigeration device adjoining it in the region of the upper right corner of the door 1. The door 1 comprises a hollow door leaf 3 filled with a heat-insulating foam material, on the inner surface thereof an elastic sealing strip 4 is attached. In the closed position of the door shown in the figure, the sealing strip 4 bears against the frame 5 of the housing 2, so that the interior of the refrigerator is closed almost airtight.
Eine Öffnung 6 an der oberen Seitenfläche des Türblatts 3 gibt den Blick in dessen Inne- res frei. Man erkennt ein hier als Wirkarm 7 bezeichnetes Element aus einem festen Kunststoff, das im wesentlichen die Gestalt einer Platte hat, mit einer in etwa rechtwinkligen Spitze 8, von der eine Flanke 9 an einem an dem Rahmen 5 angebrachten Polster 10 aus Kunststoff aufliegt, und einer Basis 11, die über einen senkrecht zur Ebene der Zeichnung verlaufenden Stift 23 (s. Fig. 4) drehfest an einen Verbindungsabschnitt 13 eines Griffs 12 gekoppelt ist. Dieser Verbindungsabschnitt 13, der schmaler als der Hauptkörper des Griffs ist, ist durch einen Schlitz an der Frontseite des Türblatts 3 in dessen Inneres eingeführt.An opening 6 on the upper side surface of the door leaf 3 exposes the inside of it. One recognizes here an element referred to as an active arm 7 made of a solid plastic, which essentially has the shape of a plate, with an approximately rectangular tip 8, of which a flank 9 rests on a plastic pad 10 attached to the frame 5, and a base 11 which is coupled in a rotationally fixed manner to a connecting section 13 of a handle 12 via a pin 23 (see FIG. 4) running perpendicular to the plane of the drawing. This connecting portion 13, which is narrower than the main body of the handle, is inserted through a slot in the front of the door panel 3 inside.
Eine Feder 14 übt ein Drehmoment im Uhrzeigersinn auf den Griff 12 und den Wirkarm 7 aus und hält diese so in der in Fig. 1 gezeigten ersten Position, in der die Spitze 8 das Polster 10 nicht oder allenfalls mit einem vernachlässigbaren Druck berührt. Wenn ein Benutzer jedoch den Griff 12 zu sich hinzieht, schwenkt dieser entgegen der Kraft der Feder 14 und dreht somit auch den Wirkarm 7, der so die Tür 1 vom Rahmen 5 forttreibt. Da bezogen auf die gemeinsame Schwenkachse 15 von Griff 12 und Wirkarm 7 der He- beiarm des Griffs 12 wesentlich länger ist als der der Spitze 8, genügt eine kleine, vom Benutzer ausgeübte Zugkraft, um mit einer erheblich größeren Kraft die Tür 1 vom Rahmen 5 abzuspreizen und so die Tür auch entgegen einem im Innern des Kältegeräts herrschenden Unterdruck zu öffnen. Im linken Randbereich der Tür ist eine zur Öffnung 6 analoge Öffnung 6' in der oberen Seitenfläche des Türblatts gebildet, in der, wie Fig. 2 zeigt, der Griff 12 und der Wirkarm 7 in spiegelbildlich analoger Weise montierbar sind. Für die spiegelbildliche Montierbarkeit genügt es, dass der Griff entlang einer horizontalen, zur Zeichnungsebene parallelen E- bene symmetrisch ist, und dass der Wirkarm 7 symmetrisch zu einer Ebene ist, die durch dessen Spitze 8 und die Schwenkachse 15 verläuft.A spring 14 exerts a clockwise torque on the handle 12 and the active arm 7 and thus holds them in the first position shown in FIG. 1, in which the tip 8 does not touch the cushion 10 or at most with a negligible pressure. However, if a user pulls the handle 12 towards him, it pivots against the force of the spring 14 and thus also rotates the active arm 7, which drives the door 1 away from the frame 5. Since, based on the common pivot axis 15 of the handle 12 and the active arm 7, the arm of the handle 12 is considerably longer than that of the tip 8, a small pulling force exerted by the user is sufficient to pull the door 1 off the frame 5 with a considerably greater force spread out and thus open the door against a negative pressure prevailing inside the refrigerator. In the left edge area of the door, an opening 6 ′ analogous to the opening 6 is formed in the upper side surface of the door leaf, in which, as shown in FIG. 2, the handle 12 and the active arm 7 can be mounted in a mirror-image analogous manner. For the mirror-image mountability, it suffices that the handle is symmetrical along a horizontal plane parallel to the plane of the drawing, and that the active arm 7 is symmetrical to a plane that runs through its tip 8 and the pivot axis 15.
Fig. 3 zeigt einen Schnitt durch das Türblatt 3 entlang der Ebene lll-lll aus Fig. 2, und Fig. 4 zeigt die Teile, die auch in Fig. 3 zu sehen sind, in einer auseinandergezogenen Dar- Stellung.FIG. 3 shows a section through the door leaf 3 along the plane III-III from FIG. 2, and FIG. 4 shows the parts that can also be seen in FIG. 3 in an exploded view.
Der obere Rand des Türblatts 3 ist durch einen Kunststoff-Formkörper 20 gebildet, der an der Frontseite den bereits erwähnten Schlitz 21 aufweist, der den Verbindungsabschnitt 13 des Griffs aufnimmt. Dieser Verbindungsabschnitt 13 besitzt eine Bohrung 22 mit qua- dratischem Querschnitt.The upper edge of the door leaf 3 is formed by a molded plastic body 20 which has the slot 21 already mentioned on the front side, which receives the connecting section 13 of the handle. This connecting section 13 has a bore 22 with a square cross section.
Der Wirkarm 7 ist einstückig mit dem bereits mit Bezug auf Fig. 1 angesprochenen Stift 23 ausgebildet. Der Stift 23 dient zum Herstellen eines Abstandes zwischen den zwei parallelen Ebenen, in denen der Wirkarm 7 und der Griff 12 drehbar sind. Die Ebene des Wirk- arms 7 muss am äußersten Rand des Türblatts 3 liegen, damit der Wirkarm 7 beim Öffnen außerhalb des Dichtstreifens 4 gegen den Rahmen 5 drücken kann; die des Griffs muss weiter zur Mitte des Türblatts 3 liegen, um eine feste Lagerung der Schwenkachse zu ermöglichen. Der Stift 23 umfasst einen ersten, breiten zylindrischen Abschnitt 24, an dem zwei radiale Schlitze 25 symmetrisch zueinander ausgebildet sind, von denen in Fig. 4 nur einer zu sehen ist. Der Schlitz 25 dient zur Aufnahme einer Spitze der Feder 14.The active arm 7 is formed in one piece with the pin 23 already mentioned with reference to FIG. 1. The pin 23 serves to establish a distance between the two parallel planes in which the active arm 7 and the handle 12 can be rotated. The plane of the knitting arm 7 must lie on the outermost edge of the door leaf 3, so that the knitting arm 7 can press against the frame 5 when it is opened outside the sealing strip 4; that of the handle must lie further to the center of the door leaf 3 in order to enable the pivot axis to be firmly supported. The pin 23 comprises a first, wide cylindrical section 24, on which two radial slots 25 are formed symmetrically to one another, of which only one can be seen in FIG. 4. The slot 25 serves to receive a tip of the spring 14.
An den ersten Abschnitt 24 des Stifts 23 schließt sich ein schmalerer zylindrischer Abschnitt 26, ein Abschnitt 27 mit quadratischem Querschnitt und eine wiederum zylindrische Spitze 28 an. Der quadratische Abschnitt 27 greift in der Fig. 3 gezeigten montierten Stellung des Wirkarms drehfest in die Bohrung 22 des Griffs 12 ein. Die Spitze 28 ist in einem Sackloch 29 des Formkörpers 20 aufgenommen und bildet so einen unteren Lagerpunkt für die Schwenkachse 15. Die Öffnung 6 ist in Fig. 3 durch eine Kappe 30 verschlossen, hier in Gestalt eines kurzen Winkelprofilelements mit einem die Öffnung 6 verdeckenden horizontalen Schenkel 31 und einem vertikalen Schenkel 32. Die Kappe 30 ist am Türblatt 3 einerseits durch zwei Kunststoffstopfen 33, die durch zwei Löcher des horizontalen Schenkels 1 in in Fig. 2 gezeigte komplementäre Löcher 34 in der oberen Seitenfläche des Türblatts rastend eingrei- fen, und zum anderen durch Rastvorsprünge 35 befestigt, die in eine Nut 36 des Formkörpers 20 eingreifen. Die Innenseite des horizontalen Schenkels 31 befindet sich auf fast ihrer gesamten Ausdehnung in Kontakt mit dem Wirkarm 7 und trägt so zur Lagefixierung der Schwenkachse 15 bei. Als Variante könnte zum gleichen Zweck an der Unterseite des horizontalen Schenkels 31 ein Stift ausgeformt sein, der in eine axiale Bohrung des Wirk- arms 7 eingreift.The first section 24 of the pin 23 is followed by a narrower cylindrical section 26, a section 27 with a square cross section and a cylindrical tip 28. In the assembled position of the active arm shown in FIG. 3, the square section 27 rotatably engages in the bore 22 of the handle 12. The tip 28 is received in a blind hole 29 of the molded body 20 and thus forms a lower bearing point for the pivot axis 15. The opening 6 is closed in Fig. 3 by a cap 30, here in the form of a short angular profile element with a horizontal leg 31 covering the opening 6 and a vertical leg 32. The cap 30 is on the door leaf 3 on the one hand by two plastic plugs 33 which pass through engage two holes of the horizontal leg 1 in complementary holes 34 shown in FIG. 2 in the upper side surface of the door leaf, and on the other hand are fastened by latching projections 35 which engage in a groove 36 of the molded body 20. The inside of the horizontal leg 31 is in contact with the active arm 7 over almost its entire extent and thus contributes to fixing the position of the pivot axis 15. As a variant, a pin could be formed on the underside of the horizontal leg 31 for the same purpose, which pin engages in an axial bore of the active arm 7.
Die zwei Löcher 34 in der Umgebung derjenigen Öffnung 6, die den Wirkarm 7 nicht aufnimmt, können zur Verankerung von Beschlagteilen des Türscharniers genutzt werden.The two holes 34 in the vicinity of the opening 6, which does not receive the active arm 7, can be used for anchoring hardware components of the door hinge.
Fig. 5 zeigt den oberen Bereich des Kältegeräts in einer Vorderansicht. Der Formkörper 20 erstreckt sich über die gesamte Breite des Türblatts 3. Oberhalb des Griffs 12 ist der vertikale Schenkel 32 der Kappe 30 zu sehen. Ein im rechten Endbereich des Formkörpers 20 ausgebildeter Schlitz, der den Griff 12 in der in Fig. 1 gezeigten Stellung aufnehmen könnte, ist durch den vertikalen Schenkel einer zweiten Kappe 35 verdeckt, der ge- ringfügig länger ist als der vertikale Schenkel 32 der Kappe 30, um eine geschlossene Frontpartie zu bilden. Um den Türanschlag zu vertauschen, genügt es, in an sich bekannter Weise die Türaufhängung 36 von der rechten auf die linke Seite des Rahmens 5 zu verlagern, die Kappen 32, 35 zu lösen, Griff 12 und Wirkarm 7 zu entnehmen, jeweils spiegelbildlich auf der anderen Seite des Türblatts wieder einzubauen und die Kappen 30, 35 ebenfalls vertauscht wieder zu montieren.Fig. 5 shows the upper area of the refrigerator in a front view. The molded body 20 extends over the entire width of the door leaf 3. Above the handle 12, the vertical leg 32 of the cap 30 can be seen. A slot formed in the right end region of the molded body 20, which could accommodate the handle 12 in the position shown in FIG. 1, is covered by the vertical leg of a second cap 35, which is slightly longer than the vertical leg 32 of the cap 30 to form a closed front section. In order to swap the door stop, it is sufficient to shift the door suspension 36 from the right to the left side of the frame 5 in a manner known per se, to loosen the caps 32, 35, to remove the handle 12 and the active arm 7, each in mirror image on the install the other side of the door panel again and replace the caps 30, 35 also interchanged.
Bei der obigen Beschreibung wurde davon ausgegangen, dass die durch Griff 12 und Wirkarm 7 gebildete Türöffnungshilfe im oberen Randbereich der Tür angeordnet ist. Es liegt auf der Hand, dass eine Anordnung im unteren Randbereich oder an einem vertika- len Rand ebenso möglich ist. Insbesondere im letzteren Fall kann ein einziger Schlitz am Türblatt vorgesehen werden, der je nach Orientierung, in der das Türblatt montiert wird, an dessen rechten oder linken Rand zu liegen kommen kann. In the above description, it was assumed that the door opening aid formed by the handle 12 and the active arm 7 is arranged in the upper edge region of the door. It is obvious that an arrangement in the lower edge area or on a vertical edge is also possible. In the latter case in particular, a single slot can be provided on the door leaf, which, depending on the orientation in which the door leaf is mounted, can come to rest on its right or left edge.
