Definitions
- Devices for cooling goods are known and are required in the cleaning, repair or maintenance of stationary refrigerated shelves or chests in supermarkets or food discounters in order to further cool the food to be chilled therein so that the cold chain is not interrupted .
- To the food is temporarily sorted into the mobile cooling device and further cooled there. After the cleaning, repair or maintenance of the stationary refrigerated shelf has been completed, the food can be removed from the temporary cooling device and put back into the corresponding refrigerated shelf.
- Such a mobile cooling device goes, for example, from the DE 10 2016 113 728 B4 emerged.
- the cooling device has a flexible hood delimiting an interior space, an assembly generating cold air and an air supply line.
- the goods to be cooled, in particular food are removed from the stationary refrigerated shelf and stacked on a pallet inside the hood.
- the air supply line extends approximately over the entire length of the hood.
- the hood and the air supply line nestle against the contours of the food in order to keep the volume to be cooled within the room as low as possible and to avoid dead volume. In a lower area of the mobile cooling device, air is sucked out of the interior and returned to the unit.
- the cooling device described can be set up quickly at appropriate locations and offers sufficient capacity to ensure sufficient cooling performance even in hot climates.
- the cooling device has a casing which surrounds an interior space, and a plurality of shelf devices arranged in the interior space.
- a shelf device consists of several shelves, each of which consists of individual struts arranged at a distance from one another.
- Cold air is generated by means of a unit and introduced into the interior via an air hose through an inlet cross-section located in the casing.
- the air located in the interior leaves the interior via an outlet cross-section located in the envelope.
- the air can circulate through the interior through the openings between the struts, so that the corpses are adequately cooled.
- the envelope is airtight.
- the cooling device can also be used to cool food at celebrations or events.
- a mobile cooling device which can be converted from a space-saving transport state to a state of use in which it provides a larger internal volume.
- the enlargement of the enclosed volume takes place in particular by folding out two side walls which are connected to a main wall of the frame on which a cooling compressor is also arranged. After folding out the side walls, floors can be inserted and an insulating cooling hood pulled over the support structure created in this way.
- the U.S. 3,256,896 reveals an enclosure, the length of which can be changed by pulling it out in the shape of an accordion.
- This known device is used for military purposes and should be able to be set up easily and quietly, in particular in the dark.
- the envelope which is firmly connected to the metallic parts of the supporting structure, consists of a fabric that has no heat-insulating properties.
- the device according to FIG U.S. 3,256,986 not suitable.
- the US 10,172,749 B2 discloses a rollable shelf device for storing corpses, which can be pulled out from a transport condition with a small enclosed volume to a use condition with a larger enclosed volume. It is pulled out by buckling horizontally running longitudinal struts, with the lower struts being deflected upwards and the upper struts downwards in the course of the folding process.
- An enclosure for the storage device and a cooling system for the stored corpses is in the US 10,172,749 B2 not disclosed.
- the invention is based on the object of providing a device for the temporary cooling of goods and a method for setting up such a device, which or which enables particularly efficient work, in particular in the sense that the transport volume of the device is reduced and the time required for erecting and dismantling the device is also reduced.
- this object is achieved according to the invention in that the support structure can be pulled out from a transport state in which it has a first length measured parallel to the floor to a use state in which it has a second length parallel to has a length measured at the bottom which is a multiple of the first length, wherein in the state of use the storage space can be at least partially enclosed by means of the casing.
- a possibly only partial enclosure of the storage room by the cover is to be understood in particular as the configuration in which the floor on which the support structure of the device is placed is not insulated, i.e. the floor directly forms the lower boundary of the storage room and thus the cover only extends to the ground. Otherwise, i.e. apart from the floor delimiting the storage space, the enclosure should be as completely closed as possible in order to minimize heat loss. However, this should not completely rule out the fact that, for example, in addition to the floor, an adjoining wall of a building is also used to delimit the storage space of the device, so that the casing can be made correspondingly smaller. In the usual case, however, only the floor is uninsulated, i.e. free of the covering.
- the device according to the invention is characterized by its particularly easy handling, since in particular no assembling or plugging of individual parts of the support structure is required, but this is always complete both in the transport and in the use state, ie includes all required components.
- various elements of the support structure can be removed from each other by relative movements, so that the length of the support structure measured in one direction of extension is variable, i.e. it can be extended during the erection process and shortened during the dismantling process.
- the device according to the invention is dispensed with in the device according to the invention.
- the device according to the invention is characterized by a particularly small transport volume, although it can be enlarged to a much larger volume in the state of use in order to generate an extremely spacious storage space in this way. The transport costs can thus be reduced not insignificantly by means of the invention.
- the small volume of the support structure not only makes it easier to transport the support structure between the individual locations, but also simplifies on-site handling. Shelves in supermarkets and food discounters are often very narrow and leave little space for the transport of large transportable cooling devices. Due to the small volume of the support structure according to the invention, it can also be maneuvered through narrow aisles and thus simplifies the setting down of the devices according to the invention at the desired location in order to be converted into the state of use there.
- a shelf device that is loose from the support structure makes it possible that the device according to the invention does not necessarily have to be positioned directly next to the stationary cooling devices. This is because the shelf devices can first be filled with the goods to be cooled and then pushed into the storage space formed by the device according to the invention. This has the advantage that the aisle in front of the stationary cooling devices can remain free, so that the cleaning staff have more space to clean the stationary cooling devices. In addition, water splashes during cleaning and gets into the aisle. A so-called wet zone is formed in front of the stationary cooling equipment to be cleaned. If the mobile cooling device were to stand in the aisle, the casing would become dirty and wear out more quickly.
- the support structure - viewed in its longitudinal direction in the state of use - has a plurality of support elements arranged one behind the other and a plurality of coupling elements each arranged between two preferably adjacent support elements, which are each articulated at their ends to the associated support elements.
- the support elements are arranged as closely as possible next to one another, that is, a distance between the individual support elements is very small, preferably less than 15 cm, more preferably less than 10 cm, even more preferably less than 5 cm.
- the distance between the individual support elements is increased in the direction of the longitudinal axis of the support structure viewed from the state of use, so that it is in the range between 50 cm and 200 cm.
- the maximum distance between the individual support elements is preferably predetermined by a maximum length of the coupling elements arranged on the support elements.
- the length of the respective coupling elements is preferably from 50 cm to 200 cm, more preferably from 80 cm to 150 cm.
- a further advantageous embodiment of the invention provides that the support elements are supported on the floor by means of support elements, in particular support struts.
- the support elements are preferably arranged perpendicular to a plane formed by the floor.
- the support elements are U- or C-shaped and can be supported with their free ends of the U or C on the floor and delimit a roof area of the storage room with a roof section and / or support a roof section of the envelope.
- the rounded shape of the support elements makes it easier to attach the heat-insulating cover, since no edges or the like cause the cover to stick.
- the casing cannot be damaged so quickly.
- a structural embodiment of the invention provides that the respective support elements can be pushed together or apart in their roof section in a direction oriented perpendicular to the longitudinal direction of the support structure. This means that the width of the supporting structure can be variably adjusted and can therefore be adapted to the aisle width of a grocery discounter.
- a maximum width of the support structure is preferably 200 cm, whereas a minimum width is 150 cm.
- the support structure preferably has a width of 160 cm.
- the coupling elements in pairs each form a coupling scissor, the two coupling elements of a coupling scissor being articulated to one another in the middle by means of a scissor axis and being articulated to two support elements at opposite ends, with at least one articulation point each Coupling element is linearly displaceable essentially perpendicular to a plane defined by the floor in the associated support elements.
- An angle ⁇ between two coupling elements which are attached to the same support element can be changed, the angle ⁇ becoming smaller and smaller as the support structure is transferred from the transport state to the use state.
- the angle ⁇ can be between 5 ° and 180 °.
- a point of articulation of a coupling element is linearly displaceable in the associated support element essentially perpendicular to the plane defined by the floor.
- a second is The articulation point of a second coupling element in the same assigned support element can only be rotated and not displaced. This has the consequence that the coupling elements are arranged again and again in the same position of use even after repeated use in the use state and in the transport state again and again in the same transport position.
- a constructive embodiment of the invention provides that a fixing element, variable in length, extends between two scissor axes of adjacent coupling scissors and can be fixed against change in length in the course of transferring the supporting structure to the state of use, the fixing element preferably having at least two movably interconnected arms which can be stiffened by means of a stiffening element, preferably by means of sliding sleeves or locking elements.
- a fixed length between the individual support elements when the support structure is in use is desirable so that the support elements do not move unexpectedly against one another.
- the arms of the fixing element are preferably telescopic.
- the fixing element can be bent in a bending axis, the arms being connected to one another in the bending axis such that they can rotate with respect to one another.
- the device according to the invention provides that the support structure can be transferred as quickly as possible from the state of use to the state of transport and in the opposite direction.
- the assembly of all individual parts by means of screws or the like would not be conducive to a quick transfer, which is why the invention provides that the linearly displaceable articulation points of the coupling elements of the coupling scissors are each guided in a groove in the support elements of the respective support element, which are aligned perpendicular to the plane defined by the floor are.
- the invention is further developed, it is provided that at least some of the support elements, preferably all support elements, each at their lower ends via wheels or rollers that can be rolled in a pull-out direction, can be supported on the floor.
- the rollability of the individual support elements has the advantage that the transfer from the transport state to the state of use and in the opposite direction is simplified, because the individual support elements do not have to be lifted to change their position to each other or to slide over the with increased frictional resistance Ground to be pulled. In case of doubt, the latter could lead to damage to the floor on which the supporting structure is arranged.
- the support elements can consequently be pushed together or apart without great resistance.
- the envelope has a plurality of longitudinal segments, the lengths of which, measured in a longitudinal direction of the supporting structure in the state of use, correspond in the sum to an equally measured overall length of the envelope and / or has two end parts, each with an opening cross-section at the end of the storage space can be closed, wherein preferably the longitudinal segments can be connected to one another in a substantially airtight manner with the aid of connecting means which run in a direction transverse to the longitudinal direction of the support structure.
- the connecting elements are preferably formed by Velcro fasteners or zip fasteners.
- the connection should preferably be made airtight so that no cold gas introduced into the storage room can unintentionally escape at the connection points.
- a width of the individual longitudinal segments preferably corresponds to a length of the course of the support element from a first contact area to a second contact area, so that the casing extends to the floor.
- This width of the respective longitudinal segment is preferably between 550 cm and 617 cm, more preferably 580 cm.
- the length of the individual longitudinal segments is between 350 cm and 450 cm, preferably 412 cm, the measured lengths of the individual longitudinal segments corresponding in total to the measured total length of the envelope, which is preferably between 1050 cm and 1350 cm, more preferably at least 1236 cm. Since the individual longitudinal segments are correspondingly smaller than the entire envelope, they allow the envelope to be handled better. Because due to a smaller area of the individual longitudinal segments in contrast to the entire envelope, they can be folded or rolled up and transported more easily and mounted on the supporting structure.
- the transferring is preferably flexible.
- the number of longitudinal segments of the envelope used can vary. This means that the total length of the supporting structure and thus the number of longitudinal segments used can be adapted to the inventory to be cooled.
- the supporting structure becomes more or less wide extended along its length and covered with the corresponding number of lengthways segments, so that the closed storage space is created.
- three longitudinal segments can be attached to a fully extended support structure. It is also conceivable, however, that a central longitudinal segment is omitted and the supporting structure is correspondingly extended less far.
- a constructive embodiment of the invention provides that the envelope can be at least partially connected to and detached from the support structure. This has the advantage that the cover and the support structure can be transported separately from one another, as a result of which the cover can be packaged in a particularly protected manner and thus damage can be largely avoided.
- the casing is firmly connected to the supporting structure. This accelerates the construction of the device, since the support structure does not first have to be brought into position and then the cover has to be attached to the support structure, but the cover is brought into position immediately when the individual support elements are pulled apart.
- the cover also has both a state of use and a state of transport.
- the cooling device is advantageously separated from the support structure and at least one air duct of the cooling device can preferably be connected to the storage space through an opening in the casing, preferably in one of its end parts.
- the cooling device can thus be transported separately from the support structure.
- the cooling device is arranged completely or at least partially outside the envelope. This has the advantage that there is more space for goods in the interior space bounded by the envelope.
- the cooling device can be variably adapted to the place of use and the respective conditions and requirements.
- An embodiment of the invention according to the invention provides that cold gas can be introduced into the storage space in an upper area of the envelope, preferably in an upper area in one of its end parts, and the heated gas in a lower area of the envelope, preferably in a lower area in one of its end faces, can be diverted from the storage room.
- the cold gas is introduced into the top of the storage room.
- the warm gas is sucked out directly below in the storage room so that the cold gas can be distributed downwards over the goods.
- the gas introduced does not heat up in such a way that it would begin to rise. Rather, it should warm gas must first be sucked off in the lower area.
- the blown gas is introduced at the top and can sink down. Air is usually used as the gas.
- the advantages cited above with regard to the cooling device also result from the method.
- the transfer of the supporting structure from a transport state to a use state and in the opposite direction can be implemented particularly quickly and without errors, since all individual parts are always completely encompassed by the support structure in both the use and transport state .
- the device according to the invention has a particularly small transport volume and can be enlarged to a much larger volume when in use, so that an extremely spacious storage space is formed. The transport and assembly costs can consequently be reduced considerably. Nevertheless, the device can also be transported in tight spaces.

Ausgehend von einer Vorrichtung der eingangs beschriebenen Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass die Tragstruktur von einem Transportzustand, in dem sie eine erste, parallel zu dem Boden gemessene Länge besitzt, in einen Gebrauchszustand ausziehbar ist, in dem sie eine zweite, parallel zu dem Boden gemessene Länge besitzt, die ein Mehrfaches der ersten Länge beträgt, wobei in dem Gebrauchszustand der Lagerraum mittels der Umhüllung zumindest teilweise umschließbar ist.Based on a device of the type described at the outset, this object is achieved according to the invention in that the support structure can be pulled out from a transport state in which it has a first length measured parallel to the floor to a use state in which it has a second length parallel to has a length measured at the bottom which is a multiple of the first length, wherein in the state of use the storage space can be at least partially enclosed by means of the casing.
Unter einer möglicherweise nur teilweisen Umschließung des Lagerraums durch die Umhüllung ist insbesondere die Ausgestaltung zu verstehen, bei der der Boden, auf dem die Tragstruktur der Vorrichtung aufgestellt ist, nicht isoliert wird, also der Boden unmittelbar die untere Begrenzung des Lagerraums bildet und somit die Umhüllung sich lediglich bis an den Boden heran erstreckt. Im Übrigen, d.h. abgesehen von einer Begrenzung des Lagerraums durch den Boden, sollte die Umhüllung möglichst vollständig geschlossen sein, um Wärmeverluste zu minimieren. Dies soll jedoch nicht gänzlich ausschließen, dass beispielsweise neben dem Boden auch eine angrenzende Wand eines Gebäudes mit als Begrenzung des Lagerraums der Vorrichtung verwendet wird, so dass die Umhüllung entsprechend kleiner ausgeführt werden kann. Im üblichen Fall ist allerdings lediglich der Boden unisoliert, d.h. frei von der Umhüllung.A possibly only partial enclosure of the storage room by the cover is to be understood in particular as the configuration in which the floor on which the support structure of the device is placed is not insulated, i.e. the floor directly forms the lower boundary of the storage room and thus the cover only extends to the ground. Otherwise, i.e. apart from the floor delimiting the storage space, the enclosure should be as completely closed as possible in order to minimize heat loss. However, this should not completely rule out the fact that, for example, in addition to the floor, an adjoining wall of a building is also used to delimit the storage space of the device, so that the casing can be made correspondingly smaller. In the usual case, however, only the floor is uninsulated, i.e. free of the covering.
Die erfindungsgemäße Vorrichtung zeichnet sich durch ihre besonders einfache Handhabbarkeit aus, da insbesondere kein Aneinanderbauen oder -stecken von Einzelteilen der Tragstruktur erforderlich ist, sondern diese sowohl im Transport- als auch im Gebrauchszustand stets vollständig ist, d.h. sämtliche benötigten Bauteile umfasst. Nach dem Prinzip eines Balgs oder einer Ziehharmonika oder eines Teleskops lassen sich verschiedene Elemente der Tragstruktur durch Relativbewegungen zueinander im Ergebnis voneinander entfernen, so dass die in eine Ausziehrichtung gemessene Länge der Tragstruktur veränderlich, d.h. beim Errichtungsvorgang verlängerbar und beim Abbauvorgang verkürzbar ist. Insbesondere entfällt bei der erfindungsgemäßen Vorrichtung ein Verschrauben oder Zusammenstecken oder das Benutzen anderer Verbindungselemente zur Schaffung einer Tragstruktur, wie sie für den Gebrauchszustand das heißt für die Einlagerung von zu kühlendem Gut erforderlich ist. Hierdurch wird der Zeitaufwand beim Handling mit der erfindungsgemäßen Vorrichtung gegenüber den Vorrichtungen nach dem Stand der Technik deutlich reduziert. Außerdem zeichnet sich die erfindungsgemäße Vorrichtung durch ein besonders kleines Transportvolumen aus, obwohl sie im Gebrauchszustand auf ein sehr viel größeres Volumen vergrößerbar ist, um auf diese Weise einen außerordentlich geräumigen Lagerraum zu erzeugen. Mittels der Erfindung lassen sich somit die Transportkosten nicht unerheblich senken.The device according to the invention is characterized by its particularly easy handling, since in particular no assembling or plugging of individual parts of the support structure is required, but this is always complete both in the transport and in the use state, ie includes all required components. According to the principle of a bellows or an accordion or a telescope, various elements of the support structure can be removed from each other by relative movements, so that the length of the support structure measured in one direction of extension is variable, i.e. it can be extended during the erection process and shortened during the dismantling process. In particular, screwing or plugging together or the use of other connecting elements to create a support structure, such as is required for the state of use, that is for the storage of goods to be cooled, is dispensed with in the device according to the invention. This reduces the time required for handling the device according to the invention compared to the Devices according to the prior art significantly reduced. In addition, the device according to the invention is characterized by a particularly small transport volume, although it can be enlarged to a much larger volume in the state of use in order to generate an extremely spacious storage space in this way. The transport costs can thus be reduced not insignificantly by means of the invention.
Durch das geringe Volumen der Tragstruktur wird nicht nur der Transport der Tragstruktur zwischen den einzelnen Einsatzorten erleichtert, sondern auch das Handling vor Ort wird vereinfacht. Häufig stehen Regale in Supermärkten und Lebensmitteldiscountern sehr eng und lassen wenig Platz für den Transport großer transportfähiger Kühlvorrichtungen. Durch das geringe Volumen der erfindungsgemäßen Tragstruktur lässt sich diese auch durch enge Gänge rangieren und vereinfacht somit das Abstellen der erfindungsgemäßen Vorrichtungen an den gewünschten Ort, um dort in den Gebrauchszustand überführt zu werden.The small volume of the support structure not only makes it easier to transport the support structure between the individual locations, but also simplifies on-site handling. Shelves in supermarkets and food discounters are often very narrow and leave little space for the transport of large transportable cooling devices. Due to the small volume of the support structure according to the invention, it can also be maneuvered through narrow aisles and thus simplifies the setting down of the devices according to the invention at the desired location in order to be converted into the state of use there.
Eine von der Tragstruktur lose Regaleinrichtung ermöglicht es, dass die erfindungsgemäße Vorrichtung nicht zwingend unmittelbar neben den stationären Kühleinrichtungen positioniert werden muss. Denn die Regaleinrichtungen können zunächst mit den zu kühlenden Gütern befüllt und anschließend in den von der erfindungsgemäßen Vorrichtung gebildeten Lagerraum geschoben werden. Dies bringt den Vorteil mit sich, dass der Gang vor den stationären Kühleinrichtungen frei bleiben kann, so dass die Reinigungskräfte mehr Freiraum zur Reinigung der stationären Kühleinrichtungen haben. Hinzu kommt, dass während der Reinigung Spritzwasser auftritt und in den Gang gelangt. Es bildet sich eine sogenannte Nasszone vor den zu reinigenden stationären Kühleinrichtungen. Würde nunmehr die mobile Kühlvorrichtung in dem Gang stehen, würde die Umhüllung verschmutzen und schneller verschleißen.A shelf device that is loose from the support structure makes it possible that the device according to the invention does not necessarily have to be positioned directly next to the stationary cooling devices. This is because the shelf devices can first be filled with the goods to be cooled and then pushed into the storage space formed by the device according to the invention. This has the advantage that the aisle in front of the stationary cooling devices can remain free, so that the cleaning staff have more space to clean the stationary cooling devices. In addition, water splashes during cleaning and gets into the aisle. A so-called wet zone is formed in front of the stationary cooling equipment to be cleaned. If the mobile cooling device were to stand in the aisle, the casing would become dirty and wear out more quickly.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Tragstruktur - in ihre Längsrichtung im Gebrauchszustand betrachtet - eine Mehrzahl hintereinander angeordneter Tragelemente und eine Mehrzahl jeweils zwischen zwei vorzugsweise benachbarten Tragelementen angeordneter Koppelelemente besitzt, die jeweils an ihren Enden gelenkig an die zugeordneten Tragelemente gekoppelt sind. In dem Transportzustand der Tragstruktur sind die Tragelemente möglichst eng nebeneinander angeordnet, das heißt, dass ein Abstand zwischen den einzelnen Tragelementen sehr gering ist, vorzugsweise weniger als 15 cm, weiter vorzugsweise weniger als 10 cm, noch weiter vorzugsweise weniger als 5 cm beträgt. Um nunmehr die Tragstruktur in ihren Gebrauchszustand zu überführen, wird der Abstand zwischen den einzelnen Tragelementen in Richtung der vom Gebrauchszustand aus betrachteten Längsachse der Tragstruktur vergrößert, so dass dieser im Bereich zwischen 50 cm und 200 cm liegt. Der maximale Abstand zwischen den einzelnen Tragelementen ist dabei vorzugsweise durch eine maximale Länge der an den Tragelementen angeordneten Koppelelemente vorgegeben. Die Länge der jeweiligen Koppelelemente beträgt vorzugsweise von 50 cm bis 200 cm, weiter vorzugsweise von 80 cm bis 150 cm.An advantageous embodiment of the invention provides that the support structure - viewed in its longitudinal direction in the state of use - has a plurality of support elements arranged one behind the other and a plurality of coupling elements each arranged between two preferably adjacent support elements, which are each articulated at their ends to the associated support elements. In the transport state of the support structure, the support elements are arranged as closely as possible next to one another, that is, a distance between the individual support elements is very small, preferably less than 15 cm, more preferably less than 10 cm, even more preferably less than 5 cm. In order to convert the support structure into its state of use, the distance between the individual support elements is increased in the direction of the longitudinal axis of the support structure viewed from the state of use, so that it is in the range between 50 cm and 200 cm. The maximum distance between the individual support elements is preferably predetermined by a maximum length of the coupling elements arranged on the support elements. The length of the respective coupling elements is preferably from 50 cm to 200 cm, more preferably from 80 cm to 150 cm.
Um einen möglichst sicheren Stand der Tragstruktur zu gewährleisten, sieht eine weitere vorteilhafte Ausgestaltung der Erfindung vor, dass die Tragelemente sich mittels Stützelementen, insbesondere Stützstreben, auf dem Boden abstützen. Die Stützelemente sind vorzugsweise senkrecht zu einer von dem Boden gebildeten Ebene angeordnet.In order to ensure that the support structure is as secure as possible, a further advantageous embodiment of the invention provides that the support elements are supported on the floor by means of support elements, in particular support struts. The support elements are preferably arranged perpendicular to a plane formed by the floor.
Erfindungsgemäß wird bevorzugt, dass die Tragelemente U- oder C-förmig ausgebildet sind und mit ihren freien Enden des U oder C auf dem Boden abstützbar sind und mit einem Dachabschnitt einen Dachbereich des Lagerraums begrenzen und/oder einen Dachabschnitt der Umhüllung abstützen. Die abgerundete Form der Tragelemente vereinfacht eine Anbringung der wärmeisolierenden Umhüllung, da keine Kanten oder ähnliches ein Hängenbleiben der Umhüllung verursachen. Hinzu kommt, dass durch die fehlenden Ecken und Kanten die Umhüllung nicht so schnell beschädigt werden kann.According to the invention it is preferred that the support elements are U- or C-shaped and can be supported with their free ends of the U or C on the floor and delimit a roof area of the storage room with a roof section and / or support a roof section of the envelope. The rounded shape of the support elements makes it easier to attach the heat-insulating cover, since no edges or the like cause the cover to stick. In addition, due to the lack of corners and edges, the casing cannot be damaged so quickly.
Eine konstruktive Ausgestaltung der Erfindung sieht vor, dass die jeweiligen Tragelemente in ihrem Dachabschnitt in einer senkrecht zur Längsrichtung der Tragstruktur ausgerichteten Richtung zusammen- oder auseinander geschoben werden können. Das heißt, dass die Tragstruktur in ihrer Breite variabel anpassbar ist und somit auf die Gangbreite eines Lebensmitteldiscounters angepasst werden kann. Eine maximale Breite der Tragstruktur beträgt vorzugsweise 200 cm, wohingegen eine minimale Breite 150 cm beträgt. Vorzugsweise weist die Tragstruktur eine Breite von 160 cm auf.A structural embodiment of the invention provides that the respective support elements can be pushed together or apart in their roof section in a direction oriented perpendicular to the longitudinal direction of the support structure. This means that the width of the supporting structure can be variably adjusted and can therefore be adapted to the aisle width of a grocery discounter. A maximum width of the support structure is preferably 200 cm, whereas a minimum width is 150 cm. The support structure preferably has a width of 160 cm.
Eine vorteilhafte Weiterentwicklung der Erfindung sieht vor, dass die Koppelelemente paarweise jeweils eine Koppelschere bilden, wobei die zwei Koppelelemente einer Koppelschere jeweils mittig mittels einer Scherenachse gelenkig miteinander verbunden sind und jeweils an gegenüberliegenden Enden mit zwei Tragelementen gelenkig verbunden sind, wobei jeweils mindestens ein Anlenkpunkt jedes Koppelelements im Wesentlichen senkrecht zu einer durch den Boden definierten Ebene in den zugeordneten Tragelementen linear verschiebbar ist. Ein Winkel α zwischen zwei Koppelelementen, die an demselben Tragelement befestigt sind, ist veränderbar, wobei der Winkel α bei der Überführung der Tragstruktur von dem Transportzustand in den Gebrauchszustand immer kleiner wird. Der Winkel α kann dabei zwischen 5° und 180° betragen. Üblicherweise ist ein Anlenkpunkt eines Koppelements im Wesentlichen senkrecht zu der durch den Boden definierten Ebene in dem zugeordneten Tragelement linear verschiebbar. Vorzugsweise ist ein zweiter Anlenkpunkt eines zweiten Koppelelements in dem gleichen zugeordneten Tragelement lediglich drehbar und nicht verschiebbar. Dies hat zur Folge, dass die Koppelemente auch nach mehrmaliger Anwendung im Gebrauchszustand immer wieder an derselben Gebrauchsposition angeordnet sind und im Transportzustand immer wieder in derselben Transportposition.An advantageous further development of the invention provides that the coupling elements in pairs each form a coupling scissor, the two coupling elements of a coupling scissor being articulated to one another in the middle by means of a scissor axis and being articulated to two support elements at opposite ends, with at least one articulation point each Coupling element is linearly displaceable essentially perpendicular to a plane defined by the floor in the associated support elements. An angle α between two coupling elements which are attached to the same support element can be changed, the angle α becoming smaller and smaller as the support structure is transferred from the transport state to the use state. The angle α can be between 5 ° and 180 °. Usually, a point of articulation of a coupling element is linearly displaceable in the associated support element essentially perpendicular to the plane defined by the floor. Preferably a second is The articulation point of a second coupling element in the same assigned support element can only be rotated and not displaced. This has the consequence that the coupling elements are arranged again and again in the same position of use even after repeated use in the use state and in the transport state again and again in the same transport position.
Eine konstruktive Ausgestaltung der Erfindung sieht vor, dass ein in seiner Länge veränderliches Fixierelement sich zwischen zwei Scherenachsen benachbarter Koppelscheren erstreckt und im Zuge einer Überführung der Tragstruktur in den Gebrauchszustand gegen Längenänderung festlegbar ist, wobei das Fixierelement vorzugsweise zumindest zwei beweglich miteinander verbundene Arme aufweist, die mittels eines Versteifungselements, vorzugsweise mittels Schiebehülsen oder Rastelementen, versteifbar sind. Eine festgelegte Länge zwischen den einzelnen Tragelementen im Gebrauchszustand der Tragstruktur ist wünschenswert, damit es nicht zu unerwarteten Bewegungen der Tragelemente gegeneinander kommt.A constructive embodiment of the invention provides that a fixing element, variable in length, extends between two scissor axes of adjacent coupling scissors and can be fixed against change in length in the course of transferring the supporting structure to the state of use, the fixing element preferably having at least two movably interconnected arms which can be stiffened by means of a stiffening element, preferably by means of sliding sleeves or locking elements. A fixed length between the individual support elements when the support structure is in use is desirable so that the support elements do not move unexpectedly against one another.
Vorzugsweise sind die Arme des Fixierelements teleskopierbar. Alternativ kann das Fixierelement in einer Knickachse knickbar sein, wobei die Arme in der Knickachse gegeneinander drehbar miteinander verbunden sind. Im Transportzustand der Tragstruktur ist es wichtig, dass diese nur sehr wenig Volumen einnimmt, weshalb es wichtig ist, dass der Abstand zwischen den einzelnen Tragelementen verringert werden kann. Aufgrund der Fixierelemente in ihrem Fixierzustand ist eine Abstandsverringerung zwischen den Tragelementen jedoch nicht möglich und soll sogar verhindert werden. Erst bei der Überführung der Tragstruktur von dem Gebrauchszustand in den Transportzustand soll das Fixierelement zusammengefahren oder in seiner Knickachse geknickt werden, so dass es in eine Lösestellung gebracht und der Abstand zwischen den einzelnen Tragelementen und somit das Volumen der Tragstruktur verringert wird.The arms of the fixing element are preferably telescopic. Alternatively, the fixing element can be bent in a bending axis, the arms being connected to one another in the bending axis such that they can rotate with respect to one another. In the transport state of the support structure, it is important that it takes up very little volume, which is why it is important that the distance between the individual support elements can be reduced. Due to the fixing elements in their fixing state, however, a reduction in the distance between the support elements is not possible and should even be prevented. Only when the support structure is transferred from the state of use to the transport state should the fixing element be moved together or bent in its articulation axis so that it is brought into a release position and the distance between the individual support elements and thus the volume of the support structure is reduced.
Die erfindungsgemäße Vorrichtung sieht vor, dass eine möglichst schnelle Überführung der Tragstruktur von dem Gebrauchszustand in den Transportzustand und in umgekehrte Richtung ermöglicht wird. Die Montage sämtlicher Einzelteile mittels Schrauben oder ähnlichen wäre nicht förderlich für eine schnelle Überführung, weshalb erfindungsgemäß vorgesehen ist, dass die linear verschiebbaren Anlenkpunkte der Koppelelemente der Koppelscheren jeweils in einer Nut in der senkrecht zu der durch den Boden definierten Ebene ausgerichteten Stützelemente des jeweiligen Tragelements geführt sind.The device according to the invention provides that the support structure can be transferred as quickly as possible from the state of use to the state of transport and in the opposite direction. The assembly of all individual parts by means of screws or the like would not be conducive to a quick transfer, which is why the invention provides that the linearly displaceable articulation points of the coupling elements of the coupling scissors are each guided in a groove in the support elements of the respective support element, which are aligned perpendicular to the plane defined by the floor are.
Die Erfindung weiter ausgestaltet, ist vorgesehen, dass mindestens einige der Tragelemente, vorzugsweise alle Tragelemente, jeweils an ihren unteren Enden über Räder oder Rollen, die in eine Ausziehrichtung rollbar sind, auf dem Boden abstützbar sind. Die Rollbarkeit der einzelnen Tragelemente bringt den Vorteil mit sich, dass die Überführung vom Transportzustand in den Gebrauchszustand und in umgekehrte Richtung vereinfacht wird, denn die einzelnen Tragelemente müssen nicht angehoben werden, um ihre Position zu einander zu verändern oder mit einem erhöhten Reibungswiderstand gleitend über den Boden gezogen werden. Letzteres könnte im Zweifelsfall zu Beschädigungen des Bodens, auf dem die Tragstruktur angeordnet ist, führen. Mittels der Räder können die Tragelemente folglich ohne einen großen Widerstand zusammen- oder auseinandergeschoben werden.The invention is further developed, it is provided that at least some of the support elements, preferably all support elements, each at their lower ends via wheels or rollers that can be rolled in a pull-out direction, can be supported on the floor. The rollability of the individual support elements has the advantage that the transfer from the transport state to the state of use and in the opposite direction is simplified, because the individual support elements do not have to be lifted to change their position to each other or to slide over the with increased frictional resistance Ground to be pulled. In case of doubt, the latter could lead to damage to the floor on which the supporting structure is arranged. By means of the wheels, the support elements can consequently be pushed together or apart without great resistance.
Eine konstruktive Weiterentwicklung der Erfindung sieht vor, dass die Umhüllung eine Mehrzahl von Längssegmenten aufweist, deren in eine Längsrichtung der Tragstruktur im Gebrauchszustand gemessenen Längen in der Summe einer ebenso gemessenen Gesamtlänge der Umhüllung entsprechen und/oder zwei Stirnteile aufweist, mit denen jeweils ein stirnseitiger Öffnungsquerschnitt des Lagerraums verschließbar ist, wobei vorzugsweise die Längssegmente mit Hilfe von Verbindungsmitteln, die in eine Richtung quer zu der Längsrichtung der Tragstruktur verlaufen, im Wesentlichen luftdicht miteinander verbindbar sind. Die Verbindungselemente werden vorzugsweise von Klettverschlüssen oder Reißverschlüssen gebildet. Die Verbindung sollte vorzugsweise luftdicht erfolgen, damit kein kaltes in den Lagerraum eingeleitetes Gas ungewollt an den Verbindungsstellen austritt.A further structural development of the invention provides that the envelope has a plurality of longitudinal segments, the lengths of which, measured in a longitudinal direction of the supporting structure in the state of use, correspond in the sum to an equally measured overall length of the envelope and / or has two end parts, each with an opening cross-section at the end of the storage space can be closed, wherein preferably the longitudinal segments can be connected to one another in a substantially airtight manner with the aid of connecting means which run in a direction transverse to the longitudinal direction of the support structure. The connecting elements are preferably formed by Velcro fasteners or zip fasteners. The connection should preferably be made airtight so that no cold gas introduced into the storage room can unintentionally escape at the connection points.
Eine Breite der einzelnen Längssegmente entspricht bevorzugt einer Länge des Verlaufs des Tragelements von einer ersten Aufstandsfläche bis zu einer zweiten Aufstandsfläche, so dass die Umhüllung bis zum Boden reicht. Diese Breite des jeweiligen Längssegments beträgt vorzugsweise zwischen 550 cm und 617 cm, weiter vorzugsweise 580 cm. Eine Länge der einzelnen Längssegmente beträgt zwischen 350 cm und 450 cm, vorzugsweise 412 cm, wobei die gemessenen Längen der einzelnen Längssegmente in Summe der gemessenen Gesamtlänge der Umhüllung entspricht, welche vorzugsweise zwischen 1050 cm und 1350 cm, weiter vorzugsweise mindestens 1236 cm beträgt. Da die einzelnen Längssegmente entsprechend kleiner sind als die gesamte Umhüllung, lassen diese ein besseres Handling der Umhüllung zu. Denn aufgrund einer kleineren Fläche der einzelnen Längssegmente im Gegensatz zu der gesamten Umhüllung lassen sich diese einfacher falten oder aufrollen und transportieren sowie an der Tragstruktur montieren. Vorzugsweise ist die Umfüllung flexibel.A width of the individual longitudinal segments preferably corresponds to a length of the course of the support element from a first contact area to a second contact area, so that the casing extends to the floor. This width of the respective longitudinal segment is preferably between 550 cm and 617 cm, more preferably 580 cm. The length of the individual longitudinal segments is between 350 cm and 450 cm, preferably 412 cm, the measured lengths of the individual longitudinal segments corresponding in total to the measured total length of the envelope, which is preferably between 1050 cm and 1350 cm, more preferably at least 1236 cm. Since the individual longitudinal segments are correspondingly smaller than the entire envelope, they allow the envelope to be handled better. Because due to a smaller area of the individual longitudinal segments in contrast to the entire envelope, they can be folded or rolled up and transported more easily and mounted on the supporting structure. The transferring is preferably flexible.
Je nach Anwendungsfall kann es hilfreich sein, dass die Anzahl der verwendeten Längssegmente der Umhüllung variieren kann. Das heißt, dass die Gesamtlänge der Tragstruktur und somit die Anzahl der verwendeten Längssegmente an den zu kühlenden Warenbestand angepasst werden kann. Die Tragstruktur wird mehr oder weniger weit entlang ihrer Längsrichtung ausgefahren und mit der entsprechenden Anzahl der Längssegmente abgedeckt, so dass der geschlossene Lagerraum entsteht. Üblicherweise können drei Längssegmente auf einer vollständig ausgefahrenen Tragstruktur angebracht werden. Denkbar ist allerdings auch, dass ein mittleres Längssegment weggelassen wird und die Tragstruktur entsprechend weniger weit ausgefahren wird.Depending on the application, it can be helpful that the number of longitudinal segments of the envelope used can vary. This means that the total length of the supporting structure and thus the number of longitudinal segments used can be adapted to the inventory to be cooled. The supporting structure becomes more or less wide extended along its length and covered with the corresponding number of lengthways segments, so that the closed storage space is created. Usually three longitudinal segments can be attached to a fully extended support structure. It is also conceivable, however, that a central longitudinal segment is omitted and the supporting structure is correspondingly extended less far.
Eine konstruktive Ausgestaltung der Erfindung sieht vor, dass die Umhüllung zumindest teilweise mit der Tragstruktur verbindbar und davon lösbar ist. Dies bringt den Vorteil mit sich, dass die Umhüllung und die Tragstruktur getrennt voneinander transportiert werden können, wodurch die Umhüllung besonders geschützt verpackt werden kann und somit Beschädigungen weitestgehend vermieden werden können. Alternativ ist erfindungsgemäß vorgesehen, dass die Umhüllung fest mit der Tragstruktur verbunden ist. Dies beschleunigt den Aufbau der Vorrichtung, da nicht erst die Tragstruktur in Position gebracht und anschließend die Umhüllung auf der Tragstruktur angebracht werden muss, sondern die Umhüllung beim auseinanderziehen der einzelnen Tragelemente unmittelbar in Position gebracht wird. Auch die Umhüllung besitzt sowohl einen Gebrauchszustand als auch einen Transportzustand.A constructive embodiment of the invention provides that the envelope can be at least partially connected to and detached from the support structure. This has the advantage that the cover and the support structure can be transported separately from one another, as a result of which the cover can be packaged in a particularly protected manner and thus damage can be largely avoided. Alternatively, it is provided according to the invention that the casing is firmly connected to the supporting structure. This accelerates the construction of the device, since the support structure does not first have to be brought into position and then the cover has to be attached to the support structure, but the cover is brought into position immediately when the individual support elements are pulled apart. The cover also has both a state of use and a state of transport.
Vorteilhafterweise ist die Kühleinrichtung von der Tragstruktur getrennt und vorzugsweise ist mindestens ein Luftkanal der Kühleinrichtung durch einen Durchbruch in der Umhüllung, vorzugsweise in einem ihrer Stirnteile, an den Lagerraum anschließbar. Die Kühleinrichtung kann somit getrennt von der Tragstruktur transportiert werden.The cooling device is advantageously separated from the support structure and at least one air duct of the cooling device can preferably be connected to the storage space through an opening in the casing, preferably in one of its end parts. The cooling device can thus be transported separately from the support structure.
Vorteilhafterweise ist vorgesehen, dass die Kühleinrichtung vollständig oder zumindest teilweise außerhalb der Umhüllung angeordnet ist. Daraus ergibt sich der Vorteil, dass in dem von der Umhüllung begrenzten Innenraum mehr Platzkapazitäten für Güter vorhanden sind. Außerdem kann die Kühleinrichtung variabel an den Einsatzort und die jeweiligen Bedingungen und Anforderungen angepasst werden.It is advantageously provided that the cooling device is arranged completely or at least partially outside the envelope. This has the advantage that there is more space for goods in the interior space bounded by the envelope. In addition, the cooling device can be variably adapted to the place of use and the respective conditions and requirements.
Eine erfindungsgemäße Ausgestaltung der Erfindung sieht vor, dass kaltes Gas in einem oberen Bereich der Umhüllung, vorzugsweise in einem oberen Bereich in einem ihrer Stirnteile, in den Lagerraum einleitbar ist, und das aufgewärmte Gas in einem unteren Bereich der Umhüllung, vorzugsweise in einem unteren Bereich in einem ihrer Stirnseite, aus dem Lagerraum ausleitbar ist. Folglich wird das kalte Gas oben in den Lagerraum eingeleitet. Das warme Gas wird direkt unten im Lagerraum herausgesogen, damit das kalte Gas sich über die Ware nach unten verteilen kann. Um eine möglichst annährend gleichmäßig kalte Gasverteilung innerhalb des Lagerraumes zu gewährleisten, ist es vorteilhaft wenn sich das eingeleitete Gas nicht derart aufheizt, dass es anfangen würde zu steigen. Vielmehr soll das warme Gas vorher im unteren Bereich abgesaugt werden. Das eingeblasene Gas wird oben eingeleitet und kann hinuntersinken. Üblicherweise wird als Gas Luft verwendet.An embodiment of the invention according to the invention provides that cold gas can be introduced into the storage space in an upper area of the envelope, preferably in an upper area in one of its end parts, and the heated gas in a lower area of the envelope, preferably in a lower area in one of its end faces, can be diverted from the storage room. As a result, the cold gas is introduced into the top of the storage room. The warm gas is sucked out directly below in the storage room so that the cold gas can be distributed downwards over the goods. In order to ensure that the gas is distributed as nearly uniformly as possible within the storage room, it is advantageous if the gas introduced does not heat up in such a way that it would begin to rise. Rather, it should warm gas must first be sucked off in the lower area. The blown gas is introduced at the top and can sink down. Air is usually used as the gas.
Ferner wird die zugrundeliegende Aufgabe durch ein Verfahren zur temporären Kühlung von Gütern mittels einer mobilen Kühlvorrichtung gelöst, wobei das Verfahren folgende Verfahrensschritte umfasst:
- Ausziehen der Tragstruktur von einem Transportzustand, in dem sie eine erste, parallel zu dem Boden gemessene Länge besitzt, in einen Gebrauchszustand, in dem sie eine zweite, parallel zu dem Boden gemessene Länge besitzt, die ein Mehrfaches der ersten Länge beträgt, wobei der Lagerraum mittels der Umhüllung in dem Gebrauchszustand der Tragstruktur zumindest teilweise umschlossen wird.
- Extending the support structure from a transport state in which it has a first length measured parallel to the floor, into a use state in which it has a second length measured parallel to the floor which is a multiple of the first length, the storage space is at least partially enclosed by means of the envelope in the state of use of the supporting structure.
Aus dem Verfahren ergeben sich ebenfalls die zuvor zu der Kühlvorrichtung angeführten Vorteile. Infolge des fehlenden Aneinanderbauens oder-steckens von Einzelteilen der Tragstruktur ist die Überführung der Tragstruktur von einem Transportzustand in einen Gebrauchszustand und in umgekehrte Richtung besonders schnell und fehlerfrei umzusetzen, da alle Einzelteile sowohl im Gebrauchs- als auch im Transportzustand stets vollständig von der Tragstruktur umfasst werden. Die erfindungsgemäße Vorrichtung hat ein besonders kleines Transportvolumen und ist im Gebrauchszustand auf ein viel größeres Volumen vergrößerbar, so dass ein außerordentlich geräumiger Lagerraum ausgebildet wird. Die Transport- sowie Montagekosten können folglich erheblich gesenkt werden. Nichtsdestotrotz kann die Vorrichtung auch in engen Räumlichkeiten transportiert werden.The advantages cited above with regard to the cooling device also result from the method. As a result of the fact that individual parts of the supporting structure are not attached to each other, the transfer of the supporting structure from a transport state to a use state and in the opposite direction can be implemented particularly quickly and without errors, since all individual parts are always completely encompassed by the support structure in both the use and transport state . The device according to the invention has a particularly small transport volume and can be enlarged to a much larger volume when in use, so that an extremely spacious storage space is formed. The transport and assembly costs can consequently be reduced considerably. Nevertheless, the device can also be transported in tight spaces.
Das Verfahren weiter ausgestaltet, ist vorgesehen, dass die Positionierung der Hülle und die Überführung der Tragstruktur von dem Transportzustand in den Gebrauchszustand separat oder zeitgleich erfolgt.In a further development of the method, it is provided that the positioning of the cover and the transfer of the support structure from the transport state to the use state take place separately or at the same time.
Schließlich sei angemerkt, dass die verschiedenen Merkmale der Unteransprüche je einzeln für sich oder zu mehreren in beliebigen Kombinationen bei Varianten der Erfindung verwirklicht sein können.Finally, it should be noted that the various features of the subclaims can be implemented individually or collectively in any combination in the case of variants of the invention.

Zur Überführung der Tragstruktur 6 vom dem Gebrauchszustand in den Transportzustand wird zunächst die Umhüllung 3 von der Tragstruktur 6 entfernt, so dass lediglich eine Tragstruktur 6 verbleibt, wie
An zwei dem Boden 5 zugewandten unteren, freien Enden 9 der Tragelemente 7, 107 befinden sich Stützelemente 10, die einen stabilen Stand der Tragstruktur 6 auf dem Boden 5 ermöglichen. Ebenfalls befinden sich an den freien Enden 9 Rollen 11, mittels derer die Tragelemente 7, 107 ohne großen Widerstand über den Boden 5 entlang einer Ausziehrichtung R zusammen- oder auseinandergeschoben werden können. Die Tragelemente 7, 107 sind U-förmig ausgebildet. Auf einem Dachabschnitt 12 der Tragelemente 7, 107 liegt die Umhüllung 3 auf und begrenzt einen Dachbereich 13 des Lagerraumes 4.
