There are motor-driven lifting cords (11, 12) to lift the support frame (6) from the chest freezer (6) and to move it upwards. Arranged in the refrigerated compartment (5) of the refrigerated chest (2) is a photocell (16) for controlling operating-hour counters which are set in motion via the photocell (16) when the support frame (6) is lowered onto the refrigerated chest (2) and are put out of action again when the support frame (6) is moved upwards. When the support frame is lowered with its covering elements, it darkens the interior compartment of the refrigerated chest and, in complete darkness, the photocells set an operating-hour counter in motion which allows the time in which the chests were covered to be recorded clearly. <IMAGE>

Description

Die Erfindung betrifft eine wärmedämmende Abdeckung an Kühltruhen, insbesondere Tiefkühltruhen, mit Abdeckelementen, die in einem Tragrahmen angeordnet sind, der in der Abdeckstellung auf dem oberen Rand der Kühltruhe aufsitzt.The invention relates to a heat-insulating cover on freezers, in particular freezers, with cover elements which are arranged in a support frame which, in the cover position, rests on the upper edge of the freezer.

Aus der DE 84 17 017 U1 ist eine Abdeckvorrichtung für Kühltruhen oder dergleichen bekannt, die als komplette selbständige Einheit auf eine Tiefkühltruhe aufgesetzt werden kann, oder es kann eine Tiefkühltruhe von vornherein mit einer derartigen Abdeckvorrichtung ausgestattet werden. Diese Abdeckvorrichtung hat einen Trägerrahmen, von dem eine horizontale, über der Öffnung des Trägerrahmens mittig angeordnete Welle getragen ist, an der zwei nebeneinander angeordnete Abdeckplatten mittels zweier verschiedener Seilzüge oder dergleichen angehängt sind. Die Welle ist motorisch, vorzugsweise von einem Elektromotor angetrieben, so daß es möglich ist, die Tiefkühltruhe durch Anheben der an den Seilzügen hängenden Abdeckplatten automatisch ohne irgendwelche, den Zugriff behindernde Gestänge abzudecken. Allerdings bringen bei dieser bekannten Abdeckvorrichtung die mit ihren inneren und äußeren Kanten an den Seilzügen angehängten Abdeckplatten Schwierigkeiten mit sich, wenn die Abdeckplatten an den Seilzügen nicht ausreichend genau und sicher angeschlagen sind, so daß sich beim Anheben und Absenken der Abdeckplatten Verkantungen ergeben, die eine einwandfreie Abdeckung der Tiefkühltruhe verhindern.DE 84 17 017 U1 discloses a covering device for freezers or the like, which can be placed as a complete, independent unit on a freezer, or a freezer can be equipped with such a covering device from the outset. This cover device has a support frame, from which a horizontal shaft, which is arranged centrally above the opening of the support frame, is supported, on which two cover plates arranged next to one another are attached by means of two different cable pulls or the like. The shaft is motorized, preferably driven by an electric motor, so that it is possible to automatically cover the freezer by lifting the cover plates hanging on the cables, without any linkage which obstructs access. Indeed bring with this known cover device with its inner and outer edges attached to the cables with difficulties when the cover plates on the cables are not attached sufficiently accurately and securely, so that there are canting when lifting and lowering the cover plates, which are perfect Prevent freezer cover.

Weiterhin ist aus DE 90 15 202 U1 eine aus leichten Stoffen bestehende Lebensmittel-Haube bekannt, die mittels Seilen an Deckenrollen hängt und am Abend auf eine darunter vorhandene Verkaufstheke gesenkt und am Morgen wieder abgehoben werden kann.Furthermore, from DE 90 15 202 U1 a food hood consisting of light materials is known, which hangs on ceiling rolls by means of ropes and can be lowered in the evening onto an existing sales counter and can be lifted off again in the morning.

Aus DE 89 09 749 U1 ist ferner eine wärmedämmende Abdeckung von Kühltruhen und insbesondere Tiefkühltruhen bekannt mit Luftschlitzen an oder zwischen den einzelnen Abdeckelementen, die den Kühlraum mit dem Raum oberhalb der Abdeckung verbinden, so daß die im Kühlraum beim Abtauvorgang aufsteigende feuchte Luft durch die Luftschlitze entweichen kann, ohne daß die in der Luft enthaltene Feuchtigkeit zu Vereisungen und zur Bildung von Eiszapfen an den Abdeckelementen führt.DE 89 09 749 U1 also discloses a heat-insulating cover for freezers and, in particular, freezers with air slots on or between the individual cover elements which connect the cooling space to the space above the cover, so that the moist air rising in the cooling space during the defrosting process through the air slots can escape without the moisture in the air leading to icing and the formation of icicles on the cover elements.

Ein Problem bei der Markteinführung und Akzeptanz solcher Abdeckungen durch die Betreiber von Lebensmittelmärkten ist der Umstand, daß die nächtliche Abdeckung der Kühltruhen ebenso wie an den Wochenenden nicht ausreichend sicher kontrolliert werden kann. Somit kann auch der Beweis für den wirtschaftlichen Erfolg dieser Maßnahmen nur schwer geführt werden, weshalb das Ziel der Energieeinsparung durch solche wärmedämmenden Abdeckungen nicht in optimaler Weise erreicht wird.A problem with the market introduction and acceptance of such covers by the operators of grocery stores is the fact that the nightly cover of the freezers cannot be controlled with sufficient certainty, just as on weekends. It is therefore difficult to prove the economic success of these measures, which is why the goal of saving energy through such thermal insulation covers is not optimally achieved.

Der Erfindung liegt die Aufgabe zugrunde, diese Schwierigkeiten zu vermeiden und eine wärmedämmende Abdeckung nach dem Oberbegriff des Anspruches 1 so auszubilden, daß eine Kontrolle des sachgerechten Einsatzes der Abdeckung in einfacher Weise möglich ist.The invention has for its object to avoid these difficulties and to form a heat-insulating cover according to the preamble of claim 1 so that a control of the correct use of the cover is possible in a simple manner.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Tragrahmen durch motorgetriebene Hubzüge von der Kühltruhe abhebbar und in der Höhe verfahrbar ist, und daß im Kühlraum der Kühltruhe eine Fotozelle angeordnet ist, zur Steuerung von Betriebsstundenzählern, die beim Absenken des Tragrahmens auf die Kühltruhe über die Fotozelle in Gang gesetzt werden und beim Hochfahren des Tragrahmens wieder außer Betrieb gehen. Besonders vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 8 gekennzeichnet.This object is achieved according to the invention in that the support frame can be lifted from the freezer and moved in height by motor-driven hoists, and in that a photo cell is arranged in the freezer's cooling chamber for controlling operating hours counters which, when the support frame is lowered onto the freezer be set in motion via the photocell and shut down again when the support frame is raised. Particularly advantageous developments of the invention are characterized in claims 2 to 8.

Die Erfindung hat den Vorteil, daß die Abdeckelemente der wärmedämmende Abdeckung nach Feierabend und an den Wochenenden nicht einzeln nacheinander auf die Kühltruhen aufgelegt und zum Betriebsbeginn wieder entfernt werden müssen. Vielmehr bietet der die Abdeckelemente aufnehmende Tragrahmen den Vorteil, daß er außer der einfachen automatischen und zeitsparenden gleichzeitigen Absenkung und Anhebung einer Vielzahl von Abdeckelementen auch eine ganze Anzahl weiterer Funktionen und Aufgaben übernehmen kann, die ohne einen solchen Tragrahmen nur schwer zu erfüllen wären. Der herabfahrende Tragrahmen mit seinen Abdeckelementen verdunkelt den Innenraum der Kühltruhe, und Fotozellen setzen bei vollständiger Dunkelheit einen Betriebsstundenzähler in Gang, der es ermöglicht, die Zeit, in der die Truhen abgedeckt waren, zweifelsfrei festzustellen.The invention has the advantage that the cover elements of the heat-insulating cover do not have to be placed one after the other on the freezers one after the other and at the weekends and have to be removed again at the start of operation. Rather, the support frame receiving the cover elements has the advantage that, in addition to the simple automatic and time-saving simultaneous lowering and raising of a large number of cover elements, it can also take on a whole number of other functions and tasks that would be difficult to accomplish without such a support frame. The descending support frame with its cover elements darkens the interior of the freezer, and photocells activate an operating hours counter in complete darkness, which enables the time in which the chests were covered to be determined without any doubt.

Der Tragrahmen zur Aufnahme der Abdeckelemente kann vorteilhaft von der Dachkonstruktion des Warenhauses oder Verkaufsraumes abgehängt werden. Eine Verbesserung der Befestigungsmöglichkeit des Tragrahmens kann dabei noch dadurch erreicht werden, daß oberhalb des die Abdeckelemente aufnehmenden Tragrahmens ein zweiter, nahezu identischer Rahmen als Montagerahmen vorgesehen ist, der seinerseits mit der Dachkonstruktion verbunden wird.The support frame for receiving the cover elements can be advantageous from the roof structure of the department store or sales room be left behind. An improvement in the possibility of fastening the support frame can be achieved in that a second, almost identical frame is provided as a mounting frame above the support frame receiving the cover elements, which in turn is connected to the roof structure.

Alternativ dazu können aber auch an den Kühltruhen nachzurüstende Säulen vorgesehen sein, die die Trage- und Führungsfunktion des Montagerahmens übernehmen.As an alternative to this, columns to be retrofitted can also be provided on the freezers, which take over the carrying and guiding function of the mounting frame.

Besonders vorteilhaft ist es dabei, daß der Tragrahmen mit den aufliegenden Abdeckelementen im abgehobenen Zustand oberhalb des Blickfeldes der Kunden über der Kühltruhe ein Deckenelement bildet, das erst abends bei Geschäftsschluß ebenso wie an Wochenenden oder sonstigen Feiertagen mittels geeigneter Elektromotoren automatisch in seine nächtliche Absenkstellung gebracht wird. Die Anordnung des mit den Abdeckelementen anhebbaren Tragrahmens hat aber auch den weiteren Vorteil, daß die Warenpräsentation im Kühlraum der Kühltruhe nicht behindert wird. Außerdem bietet die Erfindung die vorteilhafte Möglichkeit, die Abdeckelemente aus einem lichtdurchlässigen bzw. transluzenten Werkstoff herzustellen, was eine Beschattung der Ware im Kühlraum verhindert.It is particularly advantageous that the support frame with the covering elements in the raised state above the customer's field of view forms a ceiling element above the freezer, which is only automatically brought into its nightly lowering position at the end of the day as well as on weekends or other public holidays by means of suitable electric motors . The arrangement of the support frame which can be raised with the cover elements also has the further advantage that the presentation of goods in the refrigerator freezer is not hindered. In addition, the invention offers the advantageous possibility of producing the cover elements from a translucent or translucent material, which prevents shading of the goods in the cold room.

An der Kühltruhe oder an der Abdeckung können Sauglüfter angebracht sein, die gemeinsam mit den Abtauheizungen der Kühltruhe in Betrieb gehen und die warme, von der Abtauheizung der Tiefkühltruhe kommende feuchte Luft so absaugen, daß eine Beeinträchtigung der in der Kühltruhe lagernden Waren vermieden wird.Suction fans can be attached to the freezer or to the cover, which go into operation together with the defrosting heaters of the freezer and suck out the warm, moist air coming from the freezing heater of the freezer in such a way that the goods stored in the freezer are not impaired.

Besonders vorteilhaft ist es auch, wenn die Steuerung der Motoren für die vertikalen Bewegungen des gesamten Rahmens so ausgelegt ist, daß eine geringfügige einseitige Anhebung des gesamten Tragrahmens beispielsweise an einer seiner Längsseiten möglich ist, ebenfalls zur Abführung der aus dem Kühlraum beim Abtauvorgang aufsteigenden warmen Luft.It is also particularly advantageous if the control of the motors is designed for the vertical movements of the entire frame in such a way that a slight one-sided lifting of the entire support frame is possible, for example on one of its long sides, also for removing the warm air rising from the cooling space during the defrosting process .

Alternativ oder zusätzlich zu der vorteilhaften Möglichkeit, die Abdeckelemente aus einem lichtdurchlässigen bzw. transluzenten Werkstoff herzustellen, kann der Tragrahmen auch mit Aufnahmeöffnungen und Vorrichtungen zur Halterung von Leuchtstoffröhren und/oder Strahlern ausgebildet sein, was zu einer weiteren Verbesserung der Warenpräsentation führt.As an alternative or in addition to the advantageous possibility of producing the cover elements from a translucent or translucent material, the support frame can also be designed with receiving openings and devices for holding fluorescent tubes and / or spotlights, which leads to a further improvement in the presentation of the goods.
