Description

Die Erfindung bezieht sich auf eine Kühltruhe mit einem Kühltruhenabdeckungs- System zur Abdeckung eines Kühlraumes der Kühltruhe.The invention relates to a chest freezer with a chest freezer cover system for covering a refrigerator compartment of the chest freezer.

Eine Kühltruhe weist eine obenliegende und in einer horizontalen Ebene liegende Zugriffsöffnung auf. Die Kühltruhe kann vorliegend insbesondere eine gewerbliche Kühltruhe sein, die als Tiefkühltruhe mit einer Kühltemperatur von beispielsweise -18 °C oder als Kühltruhe mit einer Kühltemperatur über 0 °C sein. Um den Kühlenergie-Verbrauch möglichst gering zu halten, werden Kühltruhen entweder schon ab Werk mit einer Kühltruhenabdeckung ausgerüstet, oder aber bereits bestehende offene Kühltruhen mit einer Kühltruhenabdeckung nachgerüstet.A freezer has an overhead access opening in a horizontal plane. In the present case, the chest freezer can in particular be a commercial chest freezer, which can be used as a deep freezer with a cooling temperature of, for example, -18° C., or as a chest freezer with a cooling temperature above 0° C. In order to keep cooling energy consumption as low as possible, freezers are either fitted with a freezer cover at the factory or existing open freezers are retrofitted with a freezer cover.

Eine Kühltruhenabdeckung ist in der Regel so konzipiert, dass sie Schiebedeckel aufweist, die entweder in einer Seitwärtsvariante in Längsrichtung der Kühltruhe und parallel zu der Frontseite verschiebbar sind, oder aber in einer Schubvariante in Querrichtung und senkrecht zu der Frontseite verschiebbar sind. Auf dem Markt gibt es eine Vielzahl verschiedener Kühltruhen-Hersteller mit einer Vielzahl verschiedener Kühltruhen. Um für verschiedene Kühltruhen eine Kühltruhenabdeckung mit Schiebedeckeln sowohl in der Schubvariante als auch in der Seitwärtsvariante anbieten zu können, muss eine Vielzahl von Schienenprofilen vorgehalten werden.A chest freezer cover is usually designed in such a way that it has sliding lids that can be slid either in a sideways variant in the longitudinal direction of the chest freezer and parallel to the front side, or in a sliding variant that can be slid in the transverse direction and perpendicular to the front side. There are a number of different freezer manufacturers on the market with a variety of different freezers. In order to be able to offer a freezer cover with sliding lids for various freezers, both in the sliding version and in the sideways version, a large number of rail profiles must be kept in stock.

DE 19622589 A1 und DE 19622590 A1 offenbaren eine Kühltruhenabdeckung mit einem treppenartigen Schienenprofil an den Längsseiten. DE19622589A1 and DE19622590A1 disclose a freezer cover with a stair-like rail profile on the longitudinal sides.

In WO 2013/026079 A2 ist eine Kühltruhenabdeckung offenbart, die an den Längsseiten und an einer Brücke ein treppenartiges Schienenprofil offenbart.In WO 2013/026079 A2 discloses a chest freezer cover which reveals a stair-like rail profile on the longitudinal sides and on a bridge.

Aus JP 05087439 und JPH10253241A ist jeweils eine Kühltruhenabdeckung bekannt, die von treppenartigen Schienenprofilen gebildet wird.Out of JP05087439 and JPH10253241A a freezer cover is known in each case, which is formed by stair-like rail profiles.

Aufgabe der Erfindung ist es demgegenüber, eine Kühltruhe mit einem Kühltruhenabdeckungs-System zu schaffen, das für die Herstellung verschiedener Kühltruhenabdeckungen mit einer geringen Zahl verschiedener Bauelemente auskommt. Diese Aufgabe wird erfindungsgemäß gelöst mit einer Kühltruhe mit den Merkmalen des Anspruches 1.In contrast, the object of the invention is to create a chest freezer with a chest freezer cover system that makes do with a small number of different components for the production of different chest freezer covers. This object is achieved according to the invention with a freezer having the features of claim 1.

Die erfindungsgemäße Kühltruhenabdeckung weist zwei Systemsektoren auf, der sich dadurch auszeichnet, dass jeder Systemsektor ein Schiebedeckel-Paar aufweist, dessen beide Schiebedeckel relativ zueinander verschiebbar und übereinander verschiebbar sind, so dass sich die Schiebedeckel im geöffneten Zustand teilweise oder vollständig überdecken.The freezer cover according to the invention has two system sectors, which is characterized in that each system sector has a pair of sliding covers, the two sliding covers of which can be slid relative to one another and slid over one another, so that the sliding covers partially or completely overlap when open.

Als Längsrichtung wird vorliegend die Verlaufsrichtung der Frontseite der Kühltruhe definiert. Die beiden zueinander parallelen Querseiten der Kühltruhe bzw. der Kühltruhenabdeckung definieren die Querrichtung. Die Rückseite der Kühltruhe bzw. der Kühltruhenabdeckung ist parallel zu der Frontseite. Die Rückseite kann vorliegend auch eine zweite Zugriffsseite sein, nämlich bei einer so genannten Inseltruhe, die von zwei einander gegenüberliegenden Seiten aus zugänglich ist und geöffnet werden kann.In the present case, the direction in which the front side of the chest freezer extends is defined as the longitudinal direction. The two mutually parallel transverse sides of the chest freezer or the chest freezer cover define the transverse direction. The back of the freezer or the freezer cover is parallel to the front. In the present case, the rear side can also be a second access side, namely in the case of a so-called island chest, which is accessible and can be opened from two opposite sides.

Demgegenüber ist bei einer Wandtruhe der Kühlraum nur von einer Seite aus zugänglich, nämlich von der Frontseite aus.In contrast, in the case of a wall chest, the cooling space is only accessible from one side, namely from the front.

Die Kühltruhenabdeckung besteht aus mehreren Schienenprofilen, nämlich einem Front-Schienenprofil, einem Rückseiten-Schienenprofil parallel zu dem Frontschienen-Profil und den beiden seitlichen Querseiten-Schienenprofilen. Das Front-Schienenprofil kann absolut identisch ausgebildet sein zu dem Rückseiten-Schienenprofil, insbesondere dann, wenn die betreffende Kühltruhenabdeckung sowohl von der Frontseite als auch der Rückseite aus zugänglich ist, also als eine sogenannte Inseltruhe ausgebildet ist. Alle vorgenannten Schienenprofile eines Systemsektors der Kühltruhenabdeckung weisen jeweils treppenartig zueinander und horizontal und vertikal zueinander versetzte Gleitbahnen auf, wobei der vertikale Versatz aller Schienenprofile eines Systemsektors stets gleich ist. Die beiden Schiebedeckel eines Schiebedeckel-Paares sind derart ausgebildet, dass der untere Schiebedeckel in den einander gegenüberliegenden unteren Gleitbahnen gelagert ist, und der obere Schiebedeckel in den einander gegenüberliegenden oberen Gleitbahnen gelagert ist. Der obere Schiebedeckel ist daher quer zu seiner Schieberichtung länger ausgebildet als der untere Schiebedeckel, da bei dem oberen Schiebedeckel die Spannweite zwischen den beiden Gleitbahnen um das Doppelte des horizontalen Gleitbahn-Versatzes erhöht ist. Dadurch, dass an allen vier Seiten die Schienenprofile die gleiche treppenartige Struktur haben, können sowohl für die Schubvariante als auch für die Seitwärtsvariante grundsätzlich dieselben Schienenprofile verwendet werden. Die Gleitbahnen jedes Schienenprofils können sowohl als Gleitschienen in Schieberichtung dienen als auch quer zur Schieberichtung der Schiebedeckel als Endanschläge der Schiebedeckel dienen.The freezer cover consists of several rail profiles, namely a front rail profile, a rear rail profile parallel to the front rail profile and the two lateral transverse side rail profiles. The front rail profile can be absolutely identical to the rear rail profile, especially when the relevant freezer cover is accessible from both the front and the back, ie is designed as a so-called island chest. All of the above-mentioned rail profiles of a system sector of the freezer cover each have slideways that are offset in a stair-like manner relative to one another and horizontally and vertically with respect to one another, the vertical offset of all rail profiles in a system sector always being the same. The two sliding covers of a sliding cover pair are designed in such a way that the lower sliding cover is mounted in the opposite lower slideways, and the upper sliding cover is mounted in the opposite upper slideways. The upper sliding cover is therefore longer transversely to its sliding direction than the lower sliding cover, since in the upper sliding cover the span between the two slideways is increased by twice the horizontal slideway offset. Because the rail profiles have the same step-like structure on all four sides, the same rail profiles can basically be used for both the pushing variant and the sideways variant. The slideways of each rail profile can serve both as slide rails in the sliding direction and as end stops of the sliding cover transversely to the sliding direction of the sliding cover.

Erfindungsgemäß ist für eine Schubvariante ein sich in Querrichtung erstreckendes Mittel-Schienenprofil vorgesehen, das an seinen beiden Seiten zu den jeweils gegenüberliegenden Querseiten-Schienenprofilen spiegelsymmetrisch ausgebildet ist und zwei in Längsrichtung nebeneinander liegende Systemsektoren voneinander trennt. Das Mittel-Schienenprofil wird also mit seinen beiden Längsenden in das Front-Schienenprofil und das Rückseiten-Schienenprofil eingehängt.According to the invention, a transversely extending central rail profile is provided for a thrust variant, which is mirror-symmetrical on both sides to the opposite transverse side rail profiles and separates two longitudinally adjacent system sectors from one another. The middle rail profile is thus hung with its two longitudinal ends in the front rail profile and the rear rail profile.

Für eine Seitwärtsvariante ist ein sich in Längsrichtung erstreckendes Mittel-Schienenprofil vorgesehen, das an seinen beiden Seiten zu den jeweils gegenüberliegenden Schienenprofilen, nämlich dem Front-Schienenprofil und dem Rückseiten-Schienenprofil, spiegelsymmetrisch ausgebildet ist und zwei Systemsektoren voneinander trennt. Das Mittel-Schienenprofil trennt also zwei in Querrichtung nebeneinander liegende Systemsektoren voneinander.For a sideways variant, a central rail profile extending in the longitudinal direction is provided, which is mirror-symmetrical on both sides to the opposite rail profiles, namely the front rail profile and the rear rail profile, and separates two system sectors from one another. The central rail profile thus separates two system sectors lying next to one another in the transverse direction.

Dadurch, dass alle Schienenprofile eines Systemsektors sowohl als Gleitschiene als auch als Endanschlag dienen können, wird die für die Schubvariante und die Seitwärtsvariante erforderliche Varianz an Schienenprofilen erheblich verringert. Hierdurch können erheblich größere Stückzahlen an Schienenprofilen produziert werden und ist die Lagerhaltung wegen der verringerten Varianz an Schienenprofilen vereinfacht.The fact that all rail profiles of a system sector can be used both as a sliding rail and as an end stop means that the variance in rail profiles required for the sliding variant and the lateral variant is significantly reduced. As a result, significantly larger quantities of rail profiles can be produced and warehousing is simplified because of the reduced variety of rail profiles.

Vorzugsweise in der horizontale Gleitbahnen-Versatz der beiden Gleitbahnen der Querseiten- Schienenprofile identisch mit dem horizontalen-Gleitbahnen-Versatz des Front-Schienenprofils bzw. des Rückseiten-Schienenprofils. Hierdurch wird insbesondere sichergestellt, dass die Maße der beiden Schiebedeckel eines Schiebedeckel-Paares quer zur Schieberichtung sowohl für die Schubvariante als auch für die Seitwärtsvariante praktisch identisch sein kann. Auch die erforderliche Varianz der Schiebedeckel ist damit erheblich reduziert.Preferably, the horizontal slideway offset of the two slideways of the transverse side rail profiles is identical to the horizontal slideway offset of the front rail profile or the rear rail profile. This ensures in particular that the dimensions of the two sliding covers of a pair of sliding covers transverse to the sliding direction for both the sliding variant and for the Sideways variant can be practically identical. The required variance of the sliding cover is thus significantly reduced.

Vorzugsweise sind die Gleitbahnen der Querseiten- Schienenprofile in Querrichtung nach oben konvex gewölbt. Die Wölbung kann über die gesamte Spannweite der Querseiten- Schienenprofile uniradial ausfallen, also einen konstanten Krümmungsradius aufweisen. Durch die konvexe Wölbung der Querseiten- Schienenprofile können auch die betreffenden Schiebedeckel entsprechend gewölbt ausgebildet sein, wodurch sich eine erheblich bessere Stabilität der Schiebedeckel ergibt.The slideways of the transverse side rail profiles are preferably convexly curved upwards in the transverse direction. The curvature can be uniradial over the entire span of the transverse side rail profiles, i.e. have a constant radius of curvature. Due to the convex curvature of the transverse side rail profiles, the relevant sliding covers can also be designed correspondingly curved, which results in significantly better stability of the sliding cover.

Gemäß einer bevorzugten Ausgestaltung weisen die in Querrichtung verlaufenden Schienenprofile einerseits und die in Längsrichtung verlaufenen Schienenprofile andererseits komplementäre Formschlussstrukturen auf, so dass die Schienenprofile zusammengesteckt werden können. Komplementäre Formschlussstrukturen können beispielsweise entsprechende Öffnungen einerseits und Bolzen andererseits sein. Es sind jedoch grundsätzlich auch andere Formschlussstrukturen geeignet, die einfach herstellbar sind und eine präzise Positionierung und Fixierung der miteinander verbundenen Schienenprofile sicherstellt.According to a preferred embodiment, the rail profiles running in the transverse direction on the one hand and the rail profiles running in the longitudinal direction on the other hand have complementary positive-locking structures, so that the rail profiles can be plugged together. Complementary positive-locking structures can be, for example, corresponding openings on the one hand and bolts on the other hand. In principle, however, other positive-locking structures are also suitable, which are easy to produce and ensure precise positioning and fixing of the rail profiles connected to one another.
