Definitions
- the invention relates to a door leaf for a thermally insulated compartment, in particular a refrigerator compartment of a refrigerator.
- a door leaf for a refrigerator compartment of a refrigerator should, like the walls of the refrigerator compartment, be insulated so that heat conduction through the closed refrigerator compartment door into the refrigerator compartment is avoided.
- the necessary insulation leads to a complex construction, especially since it must be taken into account that a door leaf is also subjected to a much higher mechanical load than refrigerator compartment walls, because a door leaf is also equipped with fittings for opening and closing. Forces acting on the fittings have to absorb the door leaf, which is only possible with the appropriate mechanical strength, which is guaranteed by appropriate construction measures. The resulting, not insignificant construction and assembly work increases the manufacturing costs significantly.
- the invention has for its object to form a door leaf for a thermally insulated compartment so that it can be manufactured more simply and therefore more cost-effectively.
- the door leaf is designed as a double-walled panel element filled with insulation material that consists of a flat box that is open on one side and is preferably made of sheet metal. which is closed with a sheet metal plate, preferably made of sheet metal, the edges of the flat box and the cover plate having mutually operable connecting elements.
- the flat box can be assembled with the cover plate in a simple manner by bringing existing connecting elements into operative connection with one another at the edges.
- connecting elements designed as latching elements this can be done, for example, by pressing the connecting elements located on the cover plate against the connecting elements on the edge of the flat box until the connecting elements engage with one another.
- special measures such as, for example, screwing, riveting, gluing, welding and the like, can be dispensed with, which, although they can in principle also be used for the purpose of connection within the scope of the invention, in turn require higher assembly costs.
- the necessary mechanical strength of the door panel formed from the box frame and the attached cover plate is achieved by filling it with insulation material.
- An insulating material with appropriate mechanical strength for example insulating mats that are sufficiently hard, can stiffen and solidify the door leaf and at the same time thermally insulate it.
- An advantageously simple introduction of insulating material is possible by foaming with hardening insulating material, for example polyurethane foam.
- the cover plate faces the inside of the refrigerator compartment.
- the metal cover plate thus assumes the cooling temperature prevailing in the cooling compartment when the cooling compartment is closed.
- the flat box forms the outside of the door leaf and thus has the temperature in the vicinity of the refrigerator. This creates a cold bridge in the connection areas between the flat box and cover plate is avoided, according to a development of the invention it is provided that an insulating element serving for thermal separation between the flat box and the cover plate is placed in the connection area of the connecting elements.
- the insulating element separates the connecting elements of the flat box and cover plate from one another and thermally insulates the two parts from one another, the function of mutually holding and fixing the connecting elements of the cover plate and flat box also being performed by the insulating element.
- the insulating element is a plastic profile strip arranged on the inside of the frame wall of the flat box.
- the plastic material insulates in the sense of thermal separation and the profile strip can serve with appropriate profile projections the connection between the connecting elements of the cover plate and flat box.
- the profile strip has a strip section resting against the inside of the frame wall, and a web projecting against the edge of the cover plate. With the strip section, the profile strip is supported on the frame wall of the flat box. The web projecting against the edge of the cover plate can be brought into operative connection with a connecting element seated at the edge of the cover plate.
- the web has at least one projecting rib running parallel to the strip section.
- the rib serves to stiffen the web.
- the rib has the advantage that a screw which is screwed in from the outside through the frame wall of the flat box can also be screwed into the web after penetrating the strip section, as a result of which a screw connection is considerably stronger and more durable. So that the profile strip is fixed during the assembly of a door panel, it is provided that the open edge of the opening of the flat box forming free edge of its frame wall has an inward bend that overlaps an adjacent longitudinal edge of the profile strip arranged on the inside of the frame wall.
- the easy-to-apply bend has the advantage that the opening edge of the flat box is stiffened.
- Ease of assembly is also achieved in particular in that the edges of the cover plate facing the frame wall are provided with a spring-elastically deflectable deflection directed towards the inside of the flat box, which can be brought into resilient contact with the facing longitudinal edge of the web of the profile strip. It is particularly advantageous for the bend to have a longitudinal shoulder serving to lock it with the longitudinal edge of the web of the profile strip. With these measures, the cover plate can be locked to the flat box by simply pressing it in while deflecting the bend, in that the longitudinal shoulder in the bend snaps over the longitudinal edge of the web of the profiled strip.
- a longitudinal shoulder serving for latching can be easily introduced into the bend in that it is formed by a "S" or "Z" -shaped profile of the bend.
- a spring-elastic deflection of the bend when the cover plate is pressed into the flat box is facilitated in that the bend runs at a certain angle to the cover plate plane.
- the angle of the bend is preferably approximately 45 °.
- an elastic door sealing lip can advantageously be used deploy.
- the free space is undercut by the angled bend, and the bend protrudes into the free space.
- fasteners for a door sealing lip can essentially be dispensed with. If necessary, it is sufficient to glue in the door seal lip made of foam rubber or the like.
- the parts After assembling the door leaf from the flat box, cover plate and profile strips, the parts are fixed and connected to each other by foaming with hardening insulating material.
- Polyurethane foam is particularly advantageous for foaming. This makes the door leaf extremely strong and stiff so that it can withstand mechanical loads.
- Cover plate and flat box are so firmly connected and anchored by the foaming in conjunction with undercuts formed by the bend and profile strip that a mutual solution is also exerted by tensile forces that are exerted, for example, when the cooling compartment is opened and closed via fittings and handles attached to the flat box cannot lead to the flat box and cover plate coming apart.
- the drawing shows an edge area of a door leaf for a refrigerator compartment in cross section on an enlarged scale.
- the door leaf is designed as a double-walled panel element 1.
- the panel element, or the door leaf preferably has a rectangular shape, the boundary edges of the panel element being of the same design on all sides, as shown in the drawing.
- a cover plate 2 made of sheet metal forms the inside of the refrigerator compartment facing inner wall of the double-walled panel element 1.
- a flat box 3 also made of sheet metal, forms an outer wall of the door panel.
- the laterally raised frame wall of the flat box 3 is designated by 4.
- a free edge of its frame wall 4 forming the open opening edge of the flat box 3 has an inward bend 5.
- an insulating element 6 serving for thermal separation is placed in the connection area between cover plate 2 and flat box 3, an insulating element 6 serving for thermal separation is placed.
- the insulating element is a plastic profile strip arranged on the inside of the frame wall 4 of the flat box 3, which has a strip section 7 resting on the inside of the frame wall and a web 8 projecting towards the edge of the cover plate 2. At least one rib 9 running parallel to the strip section 7 rises from the web 8.
- the rib serves to stiffen and anchor the insulating element 6, and also to hold a screw 10 indicated by dash-dotted lines, which can be screwed in from the outside Frame wall 4 of the flat box 3 bend 5 overlaps a respective adjacent longitudinal edge 11 of the profile strip arranged on the inside of the frame wall 4.
- edges of the cover plate 2 facing the frame wall 4 of the flat box 3 are provided with a spring-elastic, deflectable bend directed towards the inside of the flat box 3, which can be brought into resilient contact with the facing longitudinal edge 13 of the web 8 of the profile strip serving as insulating element 6.
- the bend runs at an angle of approximately 45 ° to the plane of the cover plate 2 and has a longitudinal shoulder 14 which serves to latch with the longitudinal edge 13 of the web 8 and which has an “S” or “Z” shaped cross section the bend 12 is formed.
- the panel element 1 can be assembled by inserting the insulating element 6, which can optionally be fixed by screws 10, and by simply pressing and snapping the cover plate 2 into the flat box. As soon as the flat box, cover plate and insulating elements have been assembled, the entire panel element is foamed with a hardening insulating material, for example polyurethane foam, thereby fixing and connecting the parts to one another. After fitting appropriate fittings, the panel element can be used as a door leaf for a refrigerator compartment.

Abstract
Description
Die Erfindung betrifft ein Türblatt für ein thermisch isoliertes Fach, insbesondere ein Kühlfach eines Kühlmöbels.The invention relates to a door leaf for a thermally insulated compartment, in particular a refrigerator compartment of a refrigerator.
Ein 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 for a refrigerator compartment of a refrigerator should, like the walls of the refrigerator compartment, be insulated so that heat conduction through the closed refrigerator compartment door into the refrigerator compartment is avoided. The necessary insulation leads to a complex construction, especially since it must be taken into account that a door leaf is also subjected to a much higher mechanical load than refrigerator compartment walls, because a door leaf is also equipped with fittings for opening and closing. Forces acting on the fittings have to absorb the door leaf, which is only possible with the appropriate mechanical strength, which is guaranteed by appropriate construction measures. The resulting, not insignificant construction and assembly work increases the manufacturing costs significantly.
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 to form a door leaf for a thermally insulated compartment so that it can be manufactured more simply and therefore more cost-effectively.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß das Türblatt als doppelwandiges, mit Isolierungsmaterial ausgefülltes Tafelelement ausgebildet ist, daß aus einem einseitig offenen, vorzugsweise aus Blech gebildeten Flachkasten besteht, der mit einer vorzugsweise aus Blech gefertigten Blechplatte verschlossen ist, wobei die Ränder des Flachkastens und der Deckplatte gegenseitig in Wirkverbindung bringbare Verbindungselemente aufweisen.This object is achieved in that the door leaf is designed as a double-walled panel element filled with insulation material that consists of a flat box that is open on one side and is preferably made of sheet metal. which is closed with a sheet metal plate, preferably made of sheet metal, the edges of the flat box and the cover plate having mutually operable connecting elements.
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 can be assembled with the cover plate in a simple manner by bringing existing connecting elements into operative connection with one another at the edges. In the case of connecting elements designed as latching elements, this can be done, for example, by pressing the connecting elements located on the cover plate against the connecting elements on the edge of the flat box until the connecting elements engage with one another. With such a configuration of the connecting elements, special measures, such as, for example, screwing, riveting, gluing, welding and the like, can be dispensed with, which, although they can in principle also be used for the purpose of connection within the scope of the invention, 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 door panel formed from the box frame and the attached cover plate is achieved by filling it with insulation material. An insulating material with appropriate mechanical strength, for example insulating mats that are sufficiently hard, can stiffen and solidify the door leaf and at the same time thermally insulate it. An advantageously simple introduction of insulating material is possible by foaming with hardening insulating material, for example polyurethane foam.
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 in den Verbindungsbereichen zwischen Flachkasten und Deckplatte vermieden wird, ist nach einer Weiterbildung der Erfindung vorgesehen, daß in den Verbindungsbereich der Verbindungselemente ein der thermischen Trennung zwischen Flachkasten und Deckplatte dienendes Isolierelement gesetzt ist. 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 faces the inside of the refrigerator compartment. The metal cover plate thus assumes the cooling temperature prevailing in the cooling compartment when the cooling compartment is closed. The flat box forms the outside of the door leaf and thus has the temperature in the vicinity of the refrigerator. This creates a cold bridge in the connection areas between the flat box and cover plate is avoided, according to a development of the invention it is provided that an insulating element serving for thermal separation between the flat box and the cover plate is placed in the connection area of the connecting elements. The insulating element separates the connecting elements of the flat box and cover plate from one another and thermally insulates the two parts from one another, the function of mutually holding and fixing the connecting elements of the cover plate and flat box also being performed by the insulating element.
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 is made possible by the fact that the insulating element is a plastic profile strip arranged on the inside of the frame wall of the flat box. The plastic material insulates in the sense of thermal separation and the profile strip can serve with appropriate profile projections the connection between the connecting elements of the cover plate and flat box. For this purpose, it is advantageously provided that the profile strip has a strip section resting against the inside of the frame wall, and a web projecting against the edge of the cover plate. With the strip section, the profile strip is supported on the frame wall of the flat box. The web projecting against the edge of the cover plate can be brought into operative connection with a connecting element seated at the edge of the cover plate.
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 Leistenabschnitts 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 has at least one projecting rib running parallel to the strip section. On the one hand, the rib serves to stiffen the web. On the other hand, the rib has the advantage that a screw which is screwed in from the outside through the frame wall of the flat box can also be screwed into the web after penetrating the strip section, as a result of which a screw connection is considerably stronger and more durable. So that the profile strip is fixed during the assembly of a door panel, it is provided that the open edge of the opening of the flat box forming free edge of its frame wall has an inward bend that overlaps an adjacent longitudinal edge of the profile strip arranged on the inside of the frame wall. In addition, the easy-to-apply bend has 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.Ease of assembly is also achieved in particular in that the edges of the cover plate facing the frame wall are provided with a spring-elastically deflectable deflection directed towards the inside of the flat box, which can be brought into resilient contact with the facing longitudinal edge of the web of the profile strip. It is particularly advantageous for the bend to have a longitudinal shoulder serving to lock it with the longitudinal edge of the web of the profile strip. With these measures, the cover plate can be locked to the flat box by simply pressing it in while deflecting the bend, in that the longitudinal shoulder in the bend snaps over the longitudinal edge of the web of the profiled strip.
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 latching can be easily introduced into the bend in that it is formed by a "S" or "Z" -shaped profile of the bend.
Eine federelastische Auslenkung der Abbiegung bei eindrückender 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 cover plate is pressed into the flat box is facilitated in that the bend runs at a certain angle to the cover plate plane. The angle of the bend is preferably approximately 45 °.
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 is limited by the bending of the free edge of the frame wall of the flat box, the section of the profile strip located behind it, the facing surface of the web of the profile strip and the bending of the cover plate, an elastic door sealing lip can advantageously be used deploy. The free space is undercut by the angled bend, and the bend protrudes into the free space. As a result, fasteners for a door sealing lip can essentially be dispensed with. If necessary, it is sufficient to glue in the door seal lip made of 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 fixed and connected to each other by foaming with hardening insulating material. Polyurethane foam is particularly advantageous for foaming. This makes the door leaf extremely strong and stiff so that it can withstand mechanical loads. Cover plate and flat box are so firmly connected and anchored by the foaming in conjunction with undercuts formed by the bend and profile strip that a mutual solution is also exerted by tensile forces that are exerted, for example, when the cooling compartment is opened and closed via fittings and handles attached to the flat box cannot lead to the flat box and cover plate coming apart.

Ein Flachkasten 3, ebenfalls aus Blech gefertigt, bildet eine Außenwand des Türblatts. Die seitlich hochgezogene Zargenwand des Flachkastens 3 ist mit 4 bezeichnet. Eine den offenen Öffnungsrand des Flachkastens 3 bildende freie Kante seiner Zargenwand 4 weist eine nach innen gerichtete Umbiegung 5 auf.

Von dem Steg 8 erhebt sich wenigstens eine parallel zum Leistenabschnitt 7 verlaufende Rippe 9. Die Rippe dient der Versteifung und Verankerung des Isolierelements 6, sowie daneben auch der Halterung einer durch strichpunktierte Linien angedeuteten, von außen einschraubbaren Schraube 10. Die an der freien Kante der Zargenwand 4 des Flachkastens 3 befindliche Umbiegung 5 übergreift eine jeweils benachbarte Längskante 11 der an der Innenseite der Zargenwand 4 angeordneten Profilleiste.A
