- This type of attachment of a receiving trough has the advantage that no additional fastening means are required, but due to the different material thicknesses that occur in principle during the manufacturing process of the interior trim, there is in principle the risk that either a locking of the receiving trough with tolerance positions of the wall thickness in the upper area, if at all then only with great effort is to be accomplished for the production personnel or, if the wall thickness is within the lower tolerances, a foam-proof installation of the receiving trough may not be possible.

- the design of the holding chamber as a closed holding frame ensures that the sealing element is printed over its entire length with approximately the same sealing force to seal the interface between the trough body and the cutout on the inner wall cladding, so that partial exit possibilities for the foaming heat insulation material are at least inherently due to the principle drastically reduced, if not completely ruled out, in addition, the holding frame which surrounds the body and is in the correct position for installation ensures that the receiving trough is fixed in position all the way around before the foaming process. Furthermore, such a holding frame can be moved into its correct holding position with relatively little effort just slide it over the body

Abstract
The invention relates to a heat insulating wall (11), such as a refrigerator housing (10), a refrigerator door or the like comprising a heat insulating layer (12) generated by foaming and located between an outer and an inner coating (13), wherein a receiver basin (17) for receiving components, such as a regulator, an illuminating body or the like, projects. Said receiving basin is held by a holding agent (23) in a segment of an inner coating (13). Said receiver basins are supported by supports in an assembly position provided with stop elements (20) and held against the heat insulation (12) opposing outer side (21) of an inner coating (13). Receiver basins (17) described in prior art comprising an inner coating (13) engaged to receiver basins reduce process safety due to inner coating wall thickness fluctuation. Assembly is made more difficult by engagement therein. The inventive receiver basin is secured by a holding clamp (23) embodied as a safety disk and located at the heat insulated side and is pulled over the basin body.
Description
Wärmeisolierende Wand, wie ein Kältegerätegehäuse, eine Kälte- gerätetür oder dergleichenHeat-insulating wall, such as a refrigerator housing, a refrigerator door or the like
Die Erfindung betrifft eine warmeisolierende Wand, wie ein Kaltegerategehause, eine Kaltegeratetur oder dergleichen mit einer zwischen einer Außen- und einer Innenverkleidung durch Aufschäumen erzeugten Warmeisolationsschicht, in welche eine zur Einbringung von Baueinheiten wie Regler, Beleuchtungskörper oder dergleichen dienende Auf- nahmemulde ragt, welche mit Haltemitteln in einem Ausschnitt der Innenverkleidung gehaltert ist und welche sich in ihrer Einbauposition mit Anschlagelementen gegen die von der Warmeisolation abgewandte Außenseite der Innenverkleidung abstutztThe invention relates to a heat-insulating wall, such as a cold appliance housing, a cold appliance or the like, with a heat insulation layer produced by foaming between an outer and an inner cladding, into which a receiving trough serving for the introduction of structural units such as controllers, lighting bodies or the like, which projects with Holding means is held in a cutout of the inner lining and which is supported in its installed position with stop elements against the outside of the inner lining facing away from the thermal insulation
Die DE-OS 198 404 29 zeigt und beschreibt ein Kaltegerategehause, an deren Innenverkleidung eine mit ihrem Muldenkorper in die Warmeisolation des Gehäuses ragende Auf- nahmemulde zur Montage einer Halogenleuchte festgesetzt ist Zur Befestigung der Aufnahmemulde ist deren Muldenkorper in einen fensterartigen Ausschnitt der Innenverkleidung eingesetzt und mit am Muldenkorper vorgesehenen rasthakenartigen Vorsprungen warmeisolationsseitig an der Innenverkleidung verrastet, wobei im Verrastungszustand sich ein umlaufend die Öffnung der Aufnahmemulde umgebender Rand sich kuhlraum- seitig an der Innenverkleidung abstutztDE-OS 198 404 29 shows and describes a cold appliance house, on the inner lining of which a receptacle protruding with its trough body into the thermal insulation of the housing is fixed for mounting a halogen lamp. The trough body is inserted into a window-like cutout of the inner lining for fastening the receptacle with detent hook-like projections provided on the body of the body latched on the heat insulation side of the inner lining, wherein in the locked state an edge surrounding the opening of the receiving recess is supported on the inner side of the inner wall of the cooling chamber
Diese Art der Befestigung einer Aufnahmemulde hat zwar den Vorzug, daß keine zusätzlichen Befestigungsmittel erforderlich sind, jedoch aufgrund der beim Herstellvorgang der Innenverkleidung prinzipbedingt auftretenden unterschiedlichen Matenalstarken prinzipiell die Gefahr besteht, daß entweder eine Verrastung der Aufnahmemulde bei Toleranzlagen der Wandstarke im oberen Bereich wenn überhaupt dann nur mit großem Kraftaufwand
für das Fertigungspersonal zu bewerkstelligen ist oder bei Wandstarken in den unteren Toleranzen gegebenenfalls kein schaumdichter Einbau der Aufnahmemulde erzielbar ist Außerdem ist eine Überprüfung der korrekten Montageposition der Aufnahmemuide im Rahmen einer kostengünstigen Sichtkontrolle nicht sicher gewahrleistet, so daß eine Fehlmontage im Sinne einer nicht korrekten Verrastung und somit ein damit zwangsläufig verbundener Schaumaustritt nicht sicher im Rahmen eines für eine Großserienfertigung kontrollierten Prozesses ausgeschlossen werden kann Die Prozeßsicherheit ist damit im wesentlichen von der Arbeitssorgfalt des Fertigungspersonals abhangigThis type of attachment of a receiving trough has the advantage that no additional fastening means are required, but due to the different material thicknesses that occur in principle during the manufacturing process of the interior trim, there is in principle the risk that either a locking of the receiving trough with tolerance positions of the wall thickness in the upper area, if at all then only with great effort is to be accomplished for the production personnel or, if the wall thickness is within the lower tolerances, a foam-proof installation of the receiving trough may not be possible.A verification of the correct mounting position of the receiving trough as part of an inexpensive visual inspection is not reliably guaranteed, so that incorrect mounting in the sense of incorrect locking and thus an inevitably associated foam leak cannot be reliably ruled out in the context of a process controlled for large-scale production. Process reliability is therefore essentially dependent on the work care of the production personnel
Der Erfindung hegt die Aufgabe zugrunde, die Prozeßsicherheit und die Montage einer Auf nahmemulde für eine warmeisoherende Wand gemäß dem Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen zu verbessernThe invention has for its object to improve the process reliability and the installation of a trough for a warm insulating wall according to the preamble of claim 1 with simple design measures
Diese Aufgabe wird gemäß der Erfindung dadurch gelost, daß als Haltemittel zumindest eine elastisch verformbare Halteklammer vorgesehen ist, welche warmeisolationsseitig form- und/oder kraftschlussig mit dem Muldenkorper zusammenwirkt und die Aufnahme- mulde form- und/oder kraftschlussig an der Innenverkleidung haltThis object is achieved according to the invention in that at least one elastically deformable holding clip is provided as the holding means, which cooperates positively and / or non-positively with the body of the heat insulation and holds the receptacle positively and / or non-positively on the inner lining
Durch die erfindungsgemaße Befestigung der Aufnahmemuide an der Innenverkleidung ist eine Qualitätskontrolle aufgrund einer bloßen Sichtuberprufung im Hinblick auf eine ordnungsgemäße Befestigung im Sinne einer positionsgenauen Lage der Halteklammern unmittelbar mit großer Sicherheit feststeilbar, wodurch die Prozeßsicherheit des Fugepro- zesses der Aufnahmemulde zur Innenverkleidung deutlich gesteigert ist Darüber hinaus ist zugleich der Einfluß der Wandstarketoleranzen auf eine ordnungsgemäße Befestigung der zu fugenden Bauteile deutlich herabgesetztDue to the fastening of the receiving guide to the inner lining according to the invention, a quality control can be determined directly with great certainty on the basis of a mere visual inspection with regard to a proper fastening in the sense of a position-accurate position of the holding clamps, whereby the process reliability of the joining process of the receiving trough to the inner lining is significantly increased In addition, the influence of the wall thickness tolerances on a proper fastening of the components to be joined is significantly reduced
Nach einer bevorzugten Ausfuhrungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Halteklammer ein umlaufend um den Muldenkorper angeordnetes Dich- tungsmittel zumindest weitestgehend gegen die Schnittstelle zwischen dem Muldenkorper und dem Ausschnitt in der Innenverkleidung zumindest weitestgehend flussigkeitsdicht anpreßtAccording to a preferred embodiment of the object of the invention, it is provided that the retaining clip at least largely presses a sealing means arranged circumferentially around the body of the body at least as far as possible against the interface between the body of the body and the cutout in the inner lining
Durch den Einsatz eines zusätzlichen, warmeisolationsseitig angeordneten Dichtungskor- pers welcher zu dem durch die Halteklammer besonders definiert an die Schnittstelle
zwischen dem Muldenkorper und dem Ausschnitt der Innenverkleidung gedruckt ist, ist mit sehr hoher Prozeßsicherheit ein Austritt des in flussigen Ausgangskomponenten zum Einsatz kommenden aufschäumenden Warmeisolationsmateπals verhindert Außerdem ist durch die warmeisolationsseitige Anordnung der Dichtung unmittelbar am Embrin- gungsort des Warmeisolationsmateπals, dessen Austritt auf die Sichtseite der Innenverkleidung, nämlich beispielsweise im Kuhlraum oder dergleichen, unterbundenThrough the use of an additional sealing body arranged on the heat insulation side, which is particularly defined at the interface by the retaining clip is printed between the trough body and the cutout of the inner cladding, a very high level of process security prevents the foaming heat insulation material used in the liquid starting components from escaping. In addition, the arrangement of the seal on the heat insulation side directly at the place of application of the heat insulation material, its exit on the visible side of the Interior cladding, namely for example in the cold room or the like, prevented
Eine besonders einfache und prozeßsichere Abdichtung der Schnittstelle zwischen dem Muldenkorper und der Innenverkleidung ist erzielt, wenn nach einer nächsten vorteilhaften Ausfuhrungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Dichtung rahmenartig ausgebildet und über den Muldenkorper gestülpt istA particularly simple and reliable sealing of the interface between the trough body and the inner lining is achieved if, according to a next advantageous embodiment of the object of the invention, it is provided that the seal is designed like a frame and placed over the trough body
Entsprechend einer nächsten bevorzugten Ausfuhrungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Halteklammer als über den Muldenkorper gestülpter Halterahmen ausgebildet ist, an dessen Rahmeninnenseite mit dem Muldenkorper form- und/oder kraftschlussig zusammenzuwirken vermögende federnde Haltenasen vorgese- hen sindAccording to a next preferred embodiment of the subject matter of the invention, it is provided that the retaining clip is designed as a holding frame which is slipped over the body of the body and on the inside of the frame of which resilient retaining lugs are to be provided which can cooperate with the body of the body in a positive and / or non-positive manner
Die Ausbildung der Haltekammer als geschlossener Halterahmen gewährleistet, daß das Dichtungselement über seine gesamte Lange mit annähernd gleicher Dichtungskraft zur Abdichtung der Schnittstelle zwischen dem Muldenkorper und dem Ausschnitt an der In- nenwandverkleidung gedruckt ist, so daß partielle Austrittsmoglichkeiten für das auf- schaumende Warmeisolationsmateπal prinzipbedingt zumindest drastisch reduziert, wenn nicht ganz und gar ausgeschlossen sind Außerdem bewirkt der den Muldenkorper umgreifende, in positionsrichtiger Einbaulage befindliche Halterahmen eine umlaufende po- sitionsstabile Befestigung der Aufnahmemulde vor dem Ausschaumvorgang Darüber hinaus laßt sich ein derartiger Halterahmen mit verhältnismäßig geringem Kraftaufwand in seine positionsrichtige Haiteposition durch ein einfaches Aufschieben über den Muldenkorper bringenThe design of the holding chamber as a closed holding frame ensures that the sealing element is printed over its entire length with approximately the same sealing force to seal the interface between the trough body and the cutout on the inner wall cladding, so that partial exit possibilities for the foaming heat insulation material are at least inherently due to the principle drastically reduced, if not completely ruled out, in addition, the holding frame which surrounds the body and is in the correct position for installation ensures that the receiving trough is fixed in position all the way around before the foaming process. Furthermore, such a holding frame can be moved into its correct holding position with relatively little effort just slide it over the body
Besonders prozeßsicher ist der Austritt des aufschäumenden Warmeisolationsmateπals verhindert, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes derThe process of preventing the foaming heat insulation material from escaping is particularly reliable if, according to a next advantageous embodiment of the object, the
Erfindung vorgesehen ist daß der Halterahmen an der Halteklammer die Dichtung war- meisolationsseitig sowohl gegen die Innenverkleidung als auch gegen den Muldenkorper
anpreßt. Durch die Kombination der als Halterahmen ausgebildeten Halteklammer in Verbindung mit einer elastisch verformbaren Dichtung läßt sich letztere durch den Haltenrahmen mit seinen in den Rahmeninnenraum vorspringenden Haltenasen problemlos zur Steigerung der Dichtungsfunktion mit einer gewissen Vorspannung gegen die Schnitt- stelle zwischen dem Muldenkörper und dem Ausschnitt an der Innenverkleidung anpressen.According to the invention, the holding frame on the holding clip seals the seal on the heat insulation side, both against the inner lining and against the body of the body presses against. The combination of the retaining clip designed as a retaining frame in conjunction with an elastically deformable seal means that the retaining frame with its retaining lugs projecting into the interior of the frame can be easily used to increase the sealing function with a certain pre-tension against the interface between the trough body and the cut-out on the Press on the inner lining.
Besonders sicher langzeitstabil positionsrichtig gehalten ist das Dichtungselement und die Aufnahmemulde, wenn nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die federnden Haltenasen des Halterahmen als zumindest annähernd über die lichte Weite seiner Rahmenabschnitte angeordneteThe sealing element and the receiving trough is particularly securely long-term stable if, according to a next preferred embodiment of the subject of the invention, it is provided that the resilient retaining lugs of the holding frame are arranged as at least approximately over the clear width of its frame sections
Halteleisten ausgebildet sind.Retaining strips are formed.
Eine derartige Halteklammer ist zudem besonders einfach und somit kostengünstig herstellbar.Such a retaining clip is also particularly simple and therefore inexpensive to manufacture.
Gemäß einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Halteleisten bezüglich des Halterahmen unter Bildung eines stumpfen Zwischenwinkels abgewinkelt sind, wobei die freien Ränder der Halteleisten im Einbauzustand des Halterahmens zur Wärmeisolationsschicht hingerichtet sind.According to a last preferred embodiment of the subject matter of the invention, it is provided that the holding strips are angled with respect to the holding frame to form an obtuse intermediate angle, the free edges of the holding strips being oriented toward the heat insulation layer when the holding frame is in the installed state.
Durch einen derartig gestalteten Halterahmen, bei welchem deren Halteleisten durch ihren Anstellwinkel bezüglich des Halterahmens eine Art Zuführhilfe bei der Montage des Halterahmens am Muldenkörper ausüben, ist die Montage einer aus elastisch verformbarem Material, wie beispielsweise Kunststoff oder Federwerkstoff, besonders erleichtert. Die abgewinkelten Halteleisten mit den an ihren freien Rändern vorgesehenen scharfen Kanten verkrallen sich in der Endmontageposition in den Kunststoffwerkstoff der Aufnahmemulde, so daß diese form- und/oder kraftschlüssig in ihrer Einbaulage gehalten ist.Such a holding frame, in which the holding strips exert a kind of feeding aid when mounting the holding frame on the body of the body due to its angle of attack relative to the holding frame, makes the assembly of an elastically deformable material, such as plastic or spring material, particularly easy. The angled retaining strips with the sharp edges provided on their free edges claw into the plastic material of the receiving trough in the final assembly position, so that it is held in its installed position in a form-fitting and / or non-positive manner.
