Die Erfindung betrifft ein Türblatt für ein thermisch isoliertes Fach, insbesondere ein Kühlfach eines Kühlmöbels, welches als doppelwandiges, mit Isoliermaterial ausgefülltes Tafelelement ausgebildet ist, das aus einem einseitig offenen, aus Metall gefertigten Flachkasten besteht, der mit einer ebenfalls aus Metall bestehenden Deckplatte verschlossen ist, wobei die Ränder des Flachkastens und der Deckplatte gegenseitig in Wirkverbindung bringbare Verbindungselemente aufweisen.The invention relates to a door leaf for a thermally insulated Compartment, in particular a refrigerator compartment of a refrigerator, which as a double-walled, filled with insulating material Panel element is formed from a one-sided open, made of metal flat box, which with a cover plate also made of metal is closed is, the edges of the flat box and the Cover plate mutually operable connecting elements exhibit.
Ein Türblatt der vorbezeichneten Gattung ist nach der Druckschrift EP-A-0 162 344 bekannt. Das Türblatt für ein Kühlfach eines Kühlmöbels soll, ebenso wie die Wände des Kühlfaches, so isoliert sein, daß Wärmeleitung durch die geschlossene Kühlfachtür in das Kühlfach hinein vermieden wird. Die notwendige Isolierung führt zu einer aufwendigen Konstruktion, zumal zu berücksichtigen ist, daß ein Türblatt auch mechanisch weitaus höher belastet wird als Kühlfachwände, weil ein Türblatt auch mit Beschlägen für das Öffnen und Schließen ausgerüstet ist. Auf die Beschläge einwirkende Kräfte hat das Türblatt abzufangen, was nur bei entsprechender mechanischer Festigkeit möglich ist, die durch entsprechende Konstruktionsmaßnahmen gewährleistet wird. Der dadurch bedingte, nicht unerhebliche Bau- und Montageaufwand erhöht die Herstellungskosten wesentlich.A door leaf of the aforementioned type is after the Document EP-A-0 162 344 known. The door leaf for one Refrigerator compartment of a refrigerator is supposed to, just like the walls of the Refrigerator compartment, so insulated that heat conduction through the closed refrigerator compartment door into the refrigerator compartment avoided becomes. The necessary insulation leads to a complex Construction, especially considering that a door leaf is also subjected to a much higher mechanical load than Refrigerator compartment walls because a door leaf also with fittings for that Open and close is equipped. On the fittings the door leaf has to intercept acting forces, which only with appropriate mechanical strength is possible by appropriate construction measures are guaranteed. Of the due to this, not inconsiderable construction and assembly work significantly increases manufacturing costs.
Der Erfindung liegt die Aufgabe zugrunde, ein Türblatt für ein thermisch isoliertes Fach so auszubilden, daß es einfacher und somit kostengünstiger hergestellt werden kann.The invention has for its object a door leaf for to form a thermally insulated compartment so that it is easier and can therefore be manufactured more cost-effectively.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß zwischen den Verbindungselementen wenigstens ein der thermischen Trennung zwischen Flachkasten und Deckplatte dienendes Isolierelement angeordnet ist, wobei durch das Isolierelement auch die Funktion der gegenseitigen Halterung und Fixierung der Verbindungselemente von Flachkasten und Deckplatte erfüllt ist.This object is achieved in that at least one of the thermal elements between the connecting elements Separation between flat box and cover plate serving Insulating element is arranged, being through the insulating element also the function of mutual holding and fixing the Fasteners of flat box and cover plate fulfilled is.
Der Flachkasten ist mit der Deckplatte in einfacher Weise zusammenfügbar, indem an den Rändern vorhandene Verbindungselemente miteinander in Wirkverbindung gebracht werden. Dies kann zum Beispiel bei als Rastelementen ausgebildeten Verbindungselementen durch Andrücken der an der Deckplatte befindlichen Verbindungselemente gegen die Verbindungselemente an dem Rand des Flachkastens erfolgen, bis die Verbindungselemente eine gegenseitige Verrastung eingehen. Bei einer derartigen Ausgestaltung der Verbindungselemente kann auf besondere Maßnahmen, wie zum Beispiel Schrauben, Nieten, Kleben, Schweißen und dergleichen verzichtet werden, die zwar auch zwecks Verbindung prinzipiell im Rahmen der Erfindung nutzbar sind, jedoch wiederum höheren Montageaufwand erfordern.The flat box is simple with the cover plate can be joined together by connecting elements present at the edges be brought into operative connection with one another. This can, for example, in the case of connecting elements designed as latching elements by pressing on the cover plate Fasteners against the fasteners done on the edge of the flat box until the fasteners enter into a mutual engagement. At such a configuration of the connecting elements special measures such as screws, rivets, Gluing, welding and the like can be dispensed with, although also for the purpose of connection in principle within the scope of the invention are usable, but in turn require higher assembly costs.
Die notwendige mechanische Festigkeit des aus Kastenrahmen und angesetzter Deckplatte gebildeten Türblatts wird durch Ausfüllen mit Isolierungsmaterial erreicht. Ein Isolierungsmaterial mit entsprechender mechanischer Festigkeit, zum Beispiel Isoliermatten, die ausreichend hart sind, kann das Türblatt versteifen und verfestigen und dabei gleichzeitig thermisch isolieren. Eine vorteilhaft einfache Einbringung von Isoliermaterial ist durch eine Ausschäumung mit aushärtendem Isoliermaterial, zum Beispiel Polyurethanschaum, möglich.The necessary mechanical strength of the box frame and the attached cover plate is formed by Filled with insulation material. An insulation material with appropriate mechanical strength, for For example, insulating mats that are sufficiently hard can do this Stiffen and solidify the door leaf and at the same time thermally insulate. An advantageous simple introduction of insulating material is through a foaming with hardening Insulating material, for example polyurethane foam, possible.
Bei dem erfindungsgemäßen Türblatt ist die Deckplatte der Kühlfachinnenseite zugekehrt. Die Deckplatte aus Metall nimmt bei geschlossenem Kühlfach somit die im Kühlfach herrschende Kühltemperatur an. Der Flachkasten bildet die Türblattaußenseite und weist somit die Temperatur in der Umgebung des Kühlmöbels auf. Damit eine Entstehung einer Kältebrücke zwischen Flachkasten und Deckplatte vermieden wird, ist das Isolierelement erfindungsgemäß zwischen den Verbindungselementen von Deckplatte und Flachkasten angeordnet. Das Isolierelement trennt die Verbindungselemente von Flachkasten und Deckplatte voneinander und isoliert die beiden Teile thermisch gegeneinander, wobei die Funktion der gegenseitigen Halterung und Fixierung der Verbindungselemente von Deckplatte und Flachkasten ebenfalls vom Isolierelement erfüllt wird.In the door leaf according to the invention, the cover plate is the The inside of the refrigerator compartment is turned. The metal cover plate takes when the refrigerator compartment is closed, the one in the refrigerator compartment Cooling temperature. The flat box forms the outside of the door leaf and thus shows the temperature in the vicinity of the Refrigerators on. This creates a cold bridge between flat box and cover plate is avoided Insulating element according to the invention between the connecting elements arranged by cover plate and flat box. The Isolating element separates the connecting elements from flat boxes and cover plate from each other and isolates the two parts thermally against each other, the function of mutual Bracket and fixation of the connecting elements of the cover plate and flat box also met by the insulating element becomes.
Diese doppelte Funktion des Isolierelements wird dadurch ermöglicht, daß das Isolierelement eine an der Innenseite der Zargenwand des Flachkastens angeordnete Profilleiste aus Kunststoff ist. Das Kunststoffmaterial isoliert im Sinne der thermischen Trennung und die Profilleiste kann mit entsprechenden Profilvorsprüngen der Verbindung zwischen den Verbindungselementen von Deckplatte und Flachkasten dienen. Zu diesem Zweck ist in vorteilhafter Weise vorgesehen, daß die Profilleiste einen an der Innenseite der Zargenwand anliegenden Leistenabschnitt hat, sowie einen gegen den Rand der Deckplatte vorstehenden Steg. Mit dem Leistenabschnitt stützt sich die Profilleiste an der Zargenwand des Flachkastens ab. Der gegen den Rand der Deckplatte vorstehende Steg kann mit einem am Rand der Deckplatte sitzenden Verbindungselement in Wirkverbindung gebracht werden.This double function of the insulating element allows the insulating element to be on the inside of the Frame wall of the flat box arranged profile bar Is plastic. The plastic material insulates in the sense of thermal separation and the profile strip can with appropriate Profile projections of the connection between the Connection elements of cover plate and flat box are used. For this purpose, it is advantageously provided that the profile bar one against the inside of the frame wall Has a groin section, as well as one against the edge the web protruding from the cover plate. With the last section the profile bar is supported on the frame wall of the flat box from. The one protruding against the edge of the cover plate Web can with a connecting element sitting on the edge of the cover plate be brought into operative connection.
Bei einer zweckmäßigen Ausgestaltung weist der Steg wenigstens eine parallel zum Leistenabschnitt verlaufende abstehende Rippe auf. Die Rippe dient zum einen der Versteifung des Stegs. Zum anderen hat die Rippe den Vorteil, daß eine von außen durch die Zargenwand des Flachkastens eingedrehte Schraube nach Durchdringen des Leistenabschnittes auch in den Steg einschraubbar ist, wodurch eine Schraubverbindung wesentlich fester und haltbarer wird. Damit die Profilleiste während des Zusammenbaus eines Türblatts fixiert ist, ist vorgesehen, daß die den offenen Öffnungsrand des Flachkastens bildende freie Kante seiner Zargenwand eine nach innen gerichtete Umbiegung aufweist, daß eine jeweils benachbarte Längskante der an der Innenseite der Zargenwand angeordneten Profilleiste übergreift. Zusätzlich hat die einfach anzubringende Umbiegung noch den Vorteil, daß der Öffnungsrand des Flachkastens vesteift wird.In an expedient embodiment, the web at least has a protruding one running parallel to the last section Rib up. The rib serves on the one hand for stiffening of the jetty. On the other hand, the rib has the advantage that one screwed in from the outside through the frame wall of the flat box After penetrating the last section, screw into the Web can be screwed in, which makes a screw connection essential becomes firmer and more durable. So that the profile bar is fixed during the assembly of a door leaf provided that the the open opening edge of the flat box free edge of its frame wall facing inwards Bend has that an adjacent longitudinal edge the one arranged on the inside of the frame wall Profile bar overlaps. In addition, the easy to install Bending the advantage that the opening edge of the Flat box is stiffened.
Eine Montageerleichterung wird auch insbesondere dadurch erreicht, daß der Zargenwand zugekehrte Ränder der Deckplatte mit einer zum Inneren des Flachkastens hin gerichteten federelastisch auslenkbaren Abbiegung versehen sind, die mit der zugekehrten Längskante des Stegs der Profilleiste in federnde Anlage bringbar ist. Mit besonderem Vorteil weist die Abbiegung eine der Verrastung mit der Längskante des Stegs der Profilleiste dienenden Längsabsatz auf. Durch diese Maßnahmen ist die Deckplatte mit dem Flachkasten durch einfaches Eindrücken unter Auslenkung der Abbiegung verrastbar, indem der Längsabsatz in der Abbiegung über die Längskante des Stegs der Profilleiste schnappt.This also makes assembly easier achieved that the edges of the cover plate facing the frame wall with a spring-elastic directed towards the inside of the flat box deflectable turn are provided with the facing longitudinal edge of the web of the profile strip in resilient Plant can be brought. The turn has a particular advantage one of the catches with the longitudinal edge of the web of Profile ledge serving longitudinal heel. Through these measures is the cover plate with the flat box by simply pushing it in can be locked by deflecting the turn by the Longitudinal heel in the turn over the long edge of the web Profile bar snaps.
Ein der Verrastung dienender Längsabsatz läßt sich in die Abbiegung dadurch einfach einbringen, daß er durch einen im Querschnitt "S"- bzw. "Z"-förmigen Verlauf der Abbiegung gebildet ist.A longitudinal shoulder serving for locking can be inserted into the Simply bring in the bend by having an im Cross section "S" - or "Z" -shaped course of the turn is formed.
Eine federelastische Auslenkung der Abbiegung bei eindrücken- der Deckplatte in den Flachkasten ist dadurch erleichtert, daß die Abbiegung in einem bestimmten Winkel zur Deckplattenebene verläuft. Vorzugsweise ist der Winkel der Abbiegung etwa 45° Grad.A spring-elastic deflection of the bend when the the cover plate in the flat box is facilitated in that the turn at a certain angle to the cover plate level runs. The angle of the bend is preferably approximately 45 ° Degree.
In dem freien Raum, welcher von der Umbiegung der freien Kante der Zargenwand des Flachkastens, dem dahinter befindlichen Abschnitt der Profilleiste, der zugekehrten Oberfläche des Stegs der Profilleiste und der Abbiegung der Deckplatte begrenzt ist, läßt sich mit Vorteil eine elastische Türdichtungslippe einsetzen. Der freie Raum ist durch die winklige Abbiegung hinterschnitten, und die Umbiegung ragt in den freien Raum hinein. Dadurch kann auf Befestigungselemente für eine Türdichtungslippe im wesentlichen verzichtet werden. Gegebenenfalls reicht es bereits aus, die Türdichtunglippe aus Moosgummi oder dergleichen einzukleben.In the free space, which depends on the bending of the free edge the frame wall of the flat box, the one behind it Section of the profile bar, the facing surface of the Web of the profile bar and the bend of the cover plate is limited, an elastic door sealing lip can be used with advantage deploy. The free space is due to the angled Undercut the bend, and the bend protrudes into the free space inside. This allows for fasteners for a door sealing lip can be essentially omitted. If necessary, it is sufficient that the door seal lip is sufficient Glue in foam rubber or the like.
Nach dem Zusammenbau des Türblatts aus Flachkasten, Deckplatte und Profilleisten werden die Teile durch eine Ausschäumung mit aushärtendem Isoliermaterial miteinander fixiert und verbunden. Für eine Ausschäumung ist Polyurethanschaum besonders vorteilhaft. Das Türblatt wird dadurch hochfest und steif, so daß es auch mechanischen Belastungen stand hält. Deckplatte und Flachkasten sind durch die Ausschäumung in Verbindung mit durch Abbiegung und Profilleiste gebildeten Hinterschneidungen derart fest miteinander verbunden und verankert, daß eine gegenseitige Lösung auch durch Zugkräfte, die zum Beispiel beim Öffnen und Schließen des Kühlfaches über an den Flachkasten angesetzte Beschläge und Handgriffe ausgeübt werden können, nicht dazu führen, daß sich Flachkasten und Deckplatte voneinander lösen.After assembling the door leaf from the flat box, cover plate and profile strips, the parts are foamed with curing insulating material fixed and connected together. Polyurethane foam is special for foaming advantageous. This makes the door leaf extremely strong and stiff that it can withstand mechanical loads. Cover plate and flat boxes are connected by the foam undercuts formed by bending and profile strip so firmly connected and anchored that a mutual solution also through tensile forces, for example when opening and closing the refrigerator compartment to the flat box attached fittings and handles can be exercised can not lead to flat box and cover plate separate from each other.
