Description
Die Erfindung betrifft eine Isolierplatte zum Abdecken von offenen Kühleinrichtungen. Im Gegensatz zu Haushaltskühltruhen werden bei Supermärkten in den Verkaufsräumen offene Gefriertruhen benutzt, bei denen durch die Raumtemperatur viel Kühlenergie aufgebracht werden muß, um in der offenen Kühltruhe die erforderliche niedrige Temperatur halten zu können. Andererseits ist während der Verkaufszeiten ein Schließen oder Abdecken dieser Kühltruhen nicht möglich, damit der Käufer jederzeit ungehindert den Inhalt wahrnehmen und auch herausnehmen kann.The invention relates to an insulating plate for Covering open cooling devices. In contrast to household freezers are in supermarkets in the sales rooms open freezers are used, where by the room temperature Much cooling energy needs to be applied to the open Freezer to keep the required low temperature. On the other hand, there is a closing during sales times or covering these freezers is not possible for the buyer perceive and remove the content at any time without hindrance can.
Außerhalb der Verkaufszeiten werden die Kühltruhen jedoch abgedeckt, insbesondere über Nacht. Hierfür werden Rollos aus Aluminiumfolie oder auch Platten genommen. Diese Platten sind aus Kunststoff mit Polyuretanausschäumung hergestellt. Die beiden Außenseiten sind mit einer glatten Alubahn beschichtet, um somit Wärmeeinstrahlungen zu verhindern. Bei den Rollos wird eine Stützeinrichtung benötigt, um ein dichtendes Aufliegen auf den Truhenrändern ohne Durchhängen zu gewährleisten. Nachteilig bei diesen Abdeckplatten ist, daß sie relativ leicht beschädigt werden können. Insbesondere auf der glatten Alufläche sind Eindrücke, Risse o.ä. leicht sichtbar, so daß auch das Aussehen schnell erheblich leidet.Outside of the sales hours, however, the freezers are covered, especially overnight. For this, blinds are made Aluminum foil or plates taken. These plates are made of plastic with polyurethane foam. The both outer sides are coated with a smooth aluminum sheet, in order to prevent heat radiation. With the blinds a support device is required to ensure that it rests tightly to ensure on the chest edges without sagging. The disadvantage of these cover plates is that they can be damaged relatively easily. Especially on the smooth aluminum surface are impressions, cracks or similar easily visible, so that the appearance quickly suffers considerably.
Ein weiterer Nachteil ist, daß diese Abdeckplatten, weil sie leicht beschädigt werden, einem relativ hohen Verbrauch unterliegen und wegen des Schaumes und Kunststoffes als Sondermüll entsorgt werden müssen. wird eine Platte beschädigt, so kommt es vor, daß der Schaum im Innern der Platte krümelig wird und in die Lebensmittel fällt. Another disadvantage is that these cover plates because they easily damaged, subject to relatively high consumption and because of the foam and plastic as special waste must be disposed of. if a plate is damaged, it comes the foam inside the plate becomes crumbly and falls into the food.
Durch die DE-B-1 803 416 ist eine Wärmeisolierung mit veränderbarem Rauminhalt vorzugsweise für Container bekannt mit einer Wabenschicht zwischen einer äußeren und inneren Hülle. Da zu Anpassung an unterschiedliche Raumverhältnisse die Wagenschicht elastisch sein soll, sind die durch die Waben gebildeten Luftkammern an ihren Enden offen. Im zusammengedrückten Zustand fällt die Luft als Isolation ganz weg. Dadurch ist die Isolationsfähigkeit nur noch auf das Material beschränkt. Außerdem benötigt diese als Auskleidung gedachte Isolierung einen Tragrahmen zu ihrer Stabilisierung. Als Isolierplatte für Kühleinrichtungen ist diese bekannte Vorrichtung nicht geeignet.DE-B-1 803 416 is a heat insulation with changeable Volume preferably known for with containers a honeycomb layer between an outer and inner shell. Because to adapt to different spatial conditions Carriage layer should be elastic, are those through the honeycomb formed air chambers open at their ends. In the squeezed As a condition, the air falls away completely as insulation. Thereby the insulation ability is only on the material limited. In addition, this is intended as a lining Insulation a support frame for their stabilization. As Insulating plate for cooling devices is this known device not suitable.
Durch die EP-A-0319 937 ist eine klappbare Abdeckung für Verkaufskühlmöbel bekannt, welche aus Hohlkammer-Polyäthylen gefertigt ist. Dieses Material enthält an diesen Stellen Luftkammern zur Isolierung, die Stege aufweisen, durch die die Abdeckung stabilisiert werden soll. Diese Stege erstrecken sich nur in Querrichtung und sind schräg so zu den Deckflächen angeordnet, daß sie nur in Querrichtung etwas zur Stabilität beitragen können. Außerdem legen sich die Stege und Deckflächen bei Durchbiegung oder Druck auf die Platte prallelogrammartig aufeinander, so daß die Größe der Luftkammern nicht garantiert ist, was sich auf den Isolierwert nachteilig auswirkt. Die Herstellung aus Polyäthylen bedingt zusätzlich die bekannten Umweltprobleme.EP-A-0319 937 is a hinged cover for refrigerated display cabinets known, which is made of hollow chamber polyethylene is. This material contains air pockets at these points for insulation, which have webs through which the Coverage should be stabilized. These webs extend only in the transverse direction and are at an angle to the top surfaces arranged that they only something in the transverse direction for stability can contribute. In addition, the webs and top surfaces are laid in the event of deflection or pressure on the plate like a parallelogram one another, so that the size of the air chambers is not guaranteed is what adversely affects the insulation value. The production from polyethylene also requires known environmental problems.
Durch die DE-C-670 090, die den nächst Kommenden Stand der Technik bildet, ist eine schalldämmende und wärmedichtende Hohlbauplatte bekannt, die eine Wellpapp-Zwischenschicht aus weichem Schrenz- oder weichem Strohpapier aufweist, die durch aneinandergereite wellpappstreifen gebildet ist. Die offenen Riffelröhren sind mit Karton abgedeckt. Abgesehen von der mangelhaften, in Quer- und Längsrichtung unterschiedlichen Steifigkeit dieser Plattenkonstruktion entstehen durch die Riffelröhren nur sehr kleine Lufträume unter hohem Materialeinsatz. Der Herstellungsaufwand ist hoch. Die Wärmedämmfähigkeit dieser bekannten Plattenkonstruktion ist nicht befriedigend.DE-C-670 090, which forms the closest state of the art, is a sound-absorbing and heat-sealing Hollow building board is known which has a corrugated cardboard intermediate layer made of soft Schrenz or soft straw paper, which is formed by corrugated cardboard strips. The open ones Corrugated tubes are covered with cardboard. Apart from the defective, different in the transverse and longitudinal directions The rigidity of this plate construction is caused by the Corrugated tubes only very small air spaces with high material use. The manufacturing effort is high. The thermal insulation ability this known plate construction is not satisfying.
Aufgabe der vorliegenden Erfindung ist es, eine gut isolierende und stabile Isolierplatte zu schaffen. Außerdem soll die Isoierlatte keine Entsorgungsprobleme mit sich bringen und auch bei Zerstörung keine Gefahr für die abgedeckten Lebensmittel beinhalten. Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 sowie auch durch die Unteransprüche gelöst.The object of the present invention is to provide a good insulation and create stable insulating plate. In addition, the Isoierlatte does not pose any disposal problems and even if destroyed, there is no danger for the food covered include. This task is characterized by the characteristics of the Claim 1 and also solved by the subclaims.
Durch die Bienenwabenstruktur entstehen eine Vielzahl von großvolumigen Luftkammern, die geschlossen sind und durch den Lufteinschluß eine recht gute Isolierwirkung haben. Die erfindungsgemäße Bauweise garantiert auch eine hohe Stabilität sowohl in Quer- als auch in Längsrichtung, so daß die Isolierplatte selbsttragend ist. Der Materialeinsatz ist relativ gering, so daß auch weniger Wärmebrücken entstehen. Wird die Isolierplatte aus Pappmaterial hergestellt, einschließlich der beiden Deckschichten, so werden damit Entsorgungsprobleme vermieden. Die Deckschichten sind zweckmäßig aus Hartkarton hergestellt, so daß die Isolierplatte eine große Festigkeit und Steifigkeit erreicht. Die Isolierfähigkeit, aber auch die Festigkeit der Platte kann dadurch verbessert werden, daß die Deckschicht nach ihrer Außenseite mit einer Reflektorfolie überzogen ist. Hierfür eignet sich insbesondere Aluminium. Weitere Einzelheiten der Erfindung werden anhand der Zeichnungen beschrieben.

Die Isolierplatte besteht aus einer Wabenschicht 1, die aus
Pappe gefertigte sechseckige Waben 11 aufweist. Diese Wabenschicht
ist in Bahnen als Meterware hergestellt und kann in
Rollen geliefert werden. Diese Wabenschicht 1 ist auf ihrer
Ober- und auf ihrer Unterseite jeweils mit einer Deckschicht 2
verklebt, so daß eine Vielzahl geschlossener Hohlräume entsteht.
Diese Deckschichten 2 bestehen ebenfalls aus Pappmaterial.
Vorzugsweise wird jedoch hierfür ein Hartkarton verwendet,
um eine stabile Fläche und Versteifung der Isolierplatte
zu erhalten. The insulating plate consists of a honeycomb layer 1, which
Cardboard made
Auf die Deckschicht 2 ist eine Reflektorschicht 3 aufgebracht,
um Wärmeeinstrahlungen abzuhalten. Gleichzeitig dient diese
Reflektorschicht 3 auch dazu, die aus Pappmaterial bestehende
Deckschicht 2 gegen Feuchtigkeit, beispielsweise Schwitzwasser,
stabil zu machen. Diese Reflektorschicht 3 besteht
zweckmäßigerweise aus Alufolie und wird mit einem PU-Kleber
(Kleber auf Polyuretanbasis) aufgezogen. Wichtig ist dabei,
daß ein dauerelastischer Kleber verwendet wird, damit ein
Reißen oder Faltenbilden der Folie vermieden wird. Dieser PU-Kleber
erfüllt diese Eigenschaften recht gut.A
Das Aufbringen des Klebers kann
Damit ist die Platte sofort fertig.The plate is now ready.
Es ist zweckmäßig die Reflektorschicht 3 besonders auszubilden,
um die Isolierplatte widerstandsfähiger zu machen. Auf
der glatten Alufolie sind Eindrücke und Kratzer sehr schnell
sichtbar und machen die Platte unansehnlich. Eine neuartige
Reflektorschicht 3, die diese Nachteile nicht hat, besteht aus
zwei Alufolien 31 und 32, zwischen welche ein Glasgitter 4 gelegt
ist, so daß eine entsprechend dem Glasgitter 4 gerippte
und damit strukturierte Reflektorschicht 3 entsteht, die dann
auf den Hartkarton aufgebracht wird, wie oben bereits beschrieben.
Das Aufbringen dieser Reflektorschicht kann in verschiedener
Weise erfolgen. Entweder es wird erst das Glasgitter
zwischen die beiden Alufolien 31 und 32 gebracht und dann
diese fertiggestellte Reflektorschicht 3 auf die Deckschicht 2
aufgezogen. Es ist aber auch möglich die Alufolien 31 und 32
sowie das Glasgitter 4 nacheinander direkt auf die Deckschicht
2 aufzuziehen. Dabei kann das Strukturgitter 4 auch unmittelbar
auf die Deckschicht 2 aufgebracht werden. Die vorgefertigte
Reflektorschicht 3 besteht dann nur aus dem Strukturgitter
4, das auf eine Reflektorfolie 31 aufgezogen ist.It is advisable to make the
Um die Isolierplatte auch an den Seiten abzuschließen, ist die
Deckschicht 2 als auch die Reflektorschicht 3 mit einer Verlängerung
21, bzw. 33, versehen, die an den Kanten der Platte
über die offene Seite heruntergezogen werden. Je nachdem, ob
die Isolierplatte noch eine Einfassung bekommt oder nicht, genügt
es die Deckschicht 2 oder auch nur die Reflektorschicht 3
zur Abdeckung der offenen Stirnflächen zu benutzen. Sofern sowohl
die Deckschicht 2 als auch die Reflektorschicht 3 über
die offenen Stirnflächen heruntergezogen ist, erübrigt sich
eine zusätzliche Einfassung der Isolierplatte.To complete the isolation plate on the sides, the
Diese so hergestellten Isolierplatten haben nicht nur eine gute
Isolationswirkung, sondern auch sehr gute mechanische Festigkeitseigenschaften.
Die Isolation ist sogar besser als die
der bekannten ausgeschäumten Kunststoffplatten. Dabei zeigt es
sich, daß Luft ein sehr guter Temperaturisolator ist. Anstelle
der sechseckigen Form der Waben können diese auch viereckig
oder besser quadratisch sein. Auch hier entstehen großvolumige
Kammern bei geringem Materialeinsatz für die jeweils gemeinsamen
Trennwände der Luftkammern. Es entstehen nur geringe Wärmebrücken.
Es kommt darauf an, daß die Hohlräume möglichst
groß sind bei verhältnismäßig geringem Materialeinsatz. Die
zentralsymmetische Form der Luftkammern bedingt außerdem eine
gleichmäßige Steifigkeit in Quer- und Längsrichtung. Wesentlich
ist aber auch die Beschichtung mit einer Reflektorschicht
3, da diese die Isolierung erheblich steigert, offensichtlich
durch die Reflektion von Wärmestrahlungen, die durch Beleuchtungskörper
oder anderes entstehen. These insulating plates produced in this way not only have a good one
Isolation effect, but also very good mechanical strength properties.
The isolation is even better than that
the well-known foamed plastic sheets. It shows
air is a very good temperature insulator. Instead of
The hexagonal shape of the honeycomb can also make it square
or better be square. Large volumes are also created here
Chambers with little use of material for the respective common
Partitions of the air chambers. There are only minor thermal bridges.
It is important that the cavities are as possible
are large with relatively little use of material. The
The central symmetrical shape of the air chambers also requires a
uniform rigidity in the transverse and longitudinal directions. Essential
is also the coating with a
Ein weiterer Vorteil dieser Platten ist, daß sie zu 100 % recyclingfähiges Material aufweisen und wesentlich preiswerter sind. Die Herstellkosten einer solchen Platte gegenüber den bekannten ausgeschäumten Platten beträgt nur etwa 70 %.Another advantage of these plates is that they are 100% Have recyclable material and much cheaper are. The manufacturing cost of such a plate compared to known foamed sheets is only about 70%.
Ein weiterer Vorteil für das Recycling wird dadurch erzielt, daß die Alufolie mit einem Kleber aufgezogen wird, der ein Abziehen der Alufolien und damit ein Trennen des Pappmaterials von dem Aluminium ermöglicht. Damit ist eine Trennung zwischen dem Pappmaterial und der Alufolie in einfacher Weise möglich.Another advantage for recycling is achieved that the aluminum foil is pulled up with an adhesive that is peeling off the aluminum foil and thus a separation of the cardboard material made possible by the aluminum. This is a separation between the cardboard material and the aluminum foil in a simple manner.
