Definitions
- the present invention relates to a refrigerated cabinet that is used to accommodate and present food to be cooled, the refrigerated cabinet comprising a plurality of doors and a storage space for food, with at least some of the doors each in an upper area on an upper slide and in a lower area are mounted on a lower slide, the storage being designed such that the doors can each be pivoted between an open position and a closed position, the upper slide being mounted so as to be displaceable along an upper guide of the refrigerated cabinet and the lower slide along a lower guide of the refrigerated cabinet , so that the doors can be moved laterally.
- Generic refrigeration cabinets are known in the art and are used, for example, in supermarkets to present the food for sale to the customer.
- a known version with laterally movable swing doors is, for example, in EP 3 178 353 B1 described.
- US 5,687,506 A relates to a fastening system for a closure element.
- the object of the present invention is to further develop a corresponding refrigerated cabinet with regard to the guidance of the doors during their lateral movement.
- the refrigerated cabinet according to the invention comprises several transparent doors (e.g. glass doors that can be single or multi-glazed), which are preferably frameless.
- the doors preferably have one Multiple glazing.
- the doors can each be pivoted about a vertical pivot axis between an open position and a closed position, with the doors closing the receiving space to the outside in the closed position.
- the corresponding door provides access to the receiving space so that food can be removed from the refrigerator or placed in it.
- the invention now provides that at least some of the doors are mounted so as to be displaceable along a guide arrangement (i.e. in addition to the aforementioned pivotability).
- the corresponding doors can therefore be pivoted about a pivot axis and additionally moved, preferably along a linear guideway.
- the slidably mounted doors can be moved in a direction that runs parallel to the vertical plane formed by the doors when they are in their closed position.
- the guide arrangement includes an upper and a lower guide so that the doors are guided in the area of their end faces.
- the slidably mounted doors can be moved in the direction mentioned by an amount which is at least 2 times, preferably at least 4 times, the width of one of the slidably mounted doors (the width representing the maximum horizontal spatial extent of a door) .
- each of the doors are each connected to an upper carriage and a lower carriage.
- each of the doors connected to a slide is connected to an upper slide in the upper area via an upper door bearing and to a lower slide in a lower area via a lower door bearing. So the door bearings are Part of the corresponding slides.
- the carriages are in contact with the guide arrangement, are displaceable relative thereto and ultimately serve to support the displaceably mounted doors relative to the guide arrangement, with the upper carriage in each case being in operative connection with the upper guide and the lower carriage in each case with the lower guide.
- the slidably mounted doors can therefore be moved along the guide arrangement together with the carriages connected to them.
- the carriages are preferably in direct contact with the guide arrangement.
- the carriages can also have one or more rollers, in particular with ball bearings, via which they are in contact with the guide arrangement.
- the rollers can have an axis of rotation that runs vertically, horizontally and obliquely to the horizontal and/or vertical.
- the carriages can also have several rollers with differently aligned axes of rotation.
- the lower carriages have corresponding rollers via which they are guided in or on the lower guide, while it is advantageous if the upper carriage is guided slidably in the upper guide.
- the lower carriage has one or more rollers, which preferably have or have a horizontally oriented axis of rotation.
- the lower guide can have one or more flat running surfaces, with the guide rollers of the carriage each resting on the or one of the guide surfaces and being moved rollingly along the respective guide surface when the door connected to the corresponding roller(s) moves.
- the weight of the doors is transferred via the rollers into the guide surface(s) before, during and after the movement of the respective door. The doors are therefore always supported downwards by the guide surface(s).
- the upper door bearings of the doors are preferably designed to be floating, i.e. the door bearings allow a relative movement between the doors and a section of the refrigerated cabinet arranged above the doors (so-called refrigerated cabinet head), so that a slight lowering cannot be prevented after a certain period of operation of the refrigerated cabinet the upper section prevents the doors from jamming.
- the refrigerated cabinet according to the invention therefore has the following advantages: by supporting the doors via the door bearings, they can be pivoted in a conventional manner between the open position and the closed position, so that food can be removed from or placed in the refrigerated cabinet. If the upper carriage is now moved under the lower carriage of one or more doors along the guide arrangement, the opening into the interior of the refrigerated cabinet can be significantly enlarged. For example, it would be conceivable to simultaneously move several adjacent upper and lower slides in the horizontal direction to such an extent that there is an opening in the receiving space of the refrigerated cabinet, the width of which corresponds to many times the width of a door. In this way, the refrigerated cabinet can be quickly and easily filled with new pallets containing food, for example using a pallet lifting device.
- the refrigerated cabinet is characterized by the fact that an upper carriage and a lower carriage, which are connected to the same door, are coupled via a vertically extending rod.
- the rod therefore extends from the lower carriage to the upper carriage and represents a mechanical coupling of both carriages.
- the rod is rotatably mounted via an upper pivot bearing on an upper carriage and a lower pivot bearing on a lower carriage (the carriages mentioned being carriages that are connected to the same door).
- the rod also includes an upper combing element which is in operative connection, in particular in direct contact, with a, preferably stationary, upper combing section of the refrigerated cabinet.
- the rod also comprises a lower combing element which is in operative connection, in particular in direct contact, with a, preferably stationary, lower combing section of the refrigeration cabinet.
- the upper combing element meshes with the upper combing section and the lower combing element meshes with the lower combing section. Since the two combing elements are connected to one another in a rotationally fixed manner via the rod, it is ensured that the doors are always guided so that they do not tip over when they are moved laterally due to the interaction of the combing elements and the combing sections, since the combing elements engage in a form-fitting manner in the combing sections.
- the invention provides the following: when a door, which is connected to an upper and a lower carriage (the carriages being coupled via a corresponding rod), is displaced laterally, the interaction of the combing elements with the combing sections causes a Rotation of the rod about a vertical axis (the combing elements are moved relative to the combing sections, with the combing elements and the combing sections each being positively connected).
- the upper combing element and the lower combing element always have the same speed due to the coupling by the rod when moving the door and thus the carriage, the upper The carriage and the lower carriage of a door inevitably move with the same acceleration or speed and over the same movement distance when they move sideways. This prevents the door from tilting or tilting while the door is being moved sideways.
- the invention therefore provides that the refrigerated cabinet has at least one door, which is coupled to an upper carriage and a lower carriage via corresponding door bearings.
- the upper carriage and the lower carriage are connected to one another via a rod, which can be rotated relative to the carriage via the pivot bearings mentioned (the pivot bearings should be designed in such a way that the rod can be rotated about a vertical axis with respect to the pivot bearings, at the same time but an axial displacement of the rod relative to the carriage is excluded). If the door is now moved laterally, i.e.
- the upper carriage and the lower carriage can only move laterally at the same time and with the same speed profile, since the combing elements mesh with the combing sections, the combing elements of a door are connected to each other in a rotationally fixed manner via the rod and can therefore only rotate at the same time and at the same speed.
- the upper combing element and the upper combing section are arranged in the vertical direction above the doors and/or the lower combing element and the lower combing section are arranged in the vertical direction below the doors.
- neither the combing elements nor the combing sections are located in the area of the doors, so that the view into the interior of the refrigerated cabinet is not disturbed by either the combing elements or the combing sections.
- the upper combing section and the upper combing element should be arranged at substantially the same vertical height. The same applies to the lower combing element and the lower combing section.
- the upper combing element and/or the lower combing element are designed as a gear (preferably as a gear with a vertically aligned axis of rotation). While it is also conceivable that the upper combing element and/or the lower combing element are each designed as a roller which has a plurality of circumferential depressions which are in operative connection with elevations of the respectively assigned combing section, the design as a gear is advantageous because it can be easily cleaned can be made and is very wear-resistant.
- the upper combing section and/or the lower combing section are formed by a link chain.
- the link chain is designed comparable to a bicycle chain.
- a link chain is arranged in the upper region of the refrigerated cabinet, which forms the upper combing section and extends over the upper region of the refrigerated cabinet in a horizontal direction.
- another link chain should be arranged in the lower area of the refrigerator, which forms the lower combing section.
- the upper link chain can be movably mounted in the vertical direction via vertically aligned bolts, the bolts engaging in corresponding bores or other recesses in a section of the refrigeration cabinet that is vertically adjacent to the link chain.
- Both the individual bolts and the individual holes are arranged at a distance from one another in the horizontal direction. If the upper area of the refrigerated cabinet, on which the upper link chain is mounted, sinks due to cold deformation, the link chain can still always align itself in the vertical direction to match the upper combing elements. The upper combing elements therefore always engage with the upper link chain.
- the upper combing section and/or the lower combing section is formed by a toothed rack.
- the rack can extend over the entire width, or at least 80% of the width, of the refrigerator. It is also conceivable that the rack composed of several rack sections arranged horizontally adjacent to one another. In any case, the rack is arranged in the vertical direction in such a way that the upper combing elements of the individual upper slides always mesh positively with the rack during the movement of the doors connected to the slides.
- the rack has teeth with a first height extending in the vertical direction, that the gears have teeth with a second height extending in the vertical direction, and that the first height is at least twice, preferably five times, The amount has the same as the second height.
- This also ensures that the combing elements still reliably comb with the corresponding rack when the door connected to the combing elements via the rod moves, even if the ceiling area of the refrigerator to which the rack is directly or indirectly attached changes over time lowered slightly.
- the height information mentioned preferably refers to the rack arranged in the upper area of the refrigerator.
- the rack arranged in the lower region, which forms the lower combing section can, however, have a height that is lower than the height of the upper rack, since the lower region of the refrigerated cabinet generally does not lower.
- the upper combing section and/or the lower combing section are arranged behind a panel, so that the upper combing section and/or the lower combing section are not visible from outside the refrigerated cabinet and when looking at the doors from the front.
- the corresponding covering preferably extends over the entire width of the respective combing section.
- an upper panel surrounds the upper combing section from above.
- a lower panel should surround the lower combing section from below or from the front (facing the refrigerator).
- the upper combing section and/or the lower combing section extends over at least 30%, preferably over at least 80%, of the width of the refrigerated cabinet.
- both the upper combing section and the lower combing section should be centrally aligned with respect to the width of the refrigerator.
- the corresponding combing sections do not have to extend over the entire width of the refrigerated cabinet, since the outer doors of the refrigerated cabinet do not necessarily have to be supported on corresponding slides.
- two doors each form a pair of doors, with the doors of a pair of doors each being mounted on a common upper carriage and a common lower carriage.
- the doors cannot therefore be moved independently of each other.
- a pair of doors i.e. two directly adjacent doors
- a pair of doors are each connected to a common upper carriage and to a common lower carriage, the said carriages in turn being coupled to one another via the rod described above.
- the rod is arranged horizontally in the middle between the two doors of a pair of doors with a view of the doors.
- the rod extends in the area of two opposite side sections of the doors of the corresponding pair of doors.
- the rod preferably has a diameter that is between 0.5 cm and 2 cm, so that the view into the interior of the refrigerator is only minimally impaired.
- the rod should be made of metal.
- the rod is made of a transparent material, for example glass or Plexiglas, so that the rod hardly impairs the view inside the refrigerator.
- the doors each have a door surface facing away from the receiving space in the closed position (the door surface is formed by the surface of the door facing the customer), the door surfaces of the doors of a first pair of doors lying in a first vertical plane in their closed position. Furthermore, the door surfaces of the doors of a second pair of doors directly adjacent to the first pair of doors should lie in a second vertical plane in their closed position. It is now advantageous if the first vertical plane and the second vertical plane run parallel to one another and are spaced apart from one another in a direction normal to the vertical planes by an amount which corresponds at least to the thickness of the doors normal to the vertical planes.
- first pair of doors and the second pair of doors are displaceable relative to one another in such a way that a door of the first pair of doors and a door of the second pair of doors at least partially overlap when the doors mentioned are in their closed position.
- first door of a pair of doors is arranged in the first vertical plane and the second door of the corresponding pair of doors is arranged in the second vertical plane when the two doors are in their closed position.
- adjacent doors are preferably arranged alternately in the first vertical plane and the second vertical plane.
- the upper carriage and/or the lower carriage are stationary relative to the upper and/or the lower guide with the aid of a fixing device can be fixed.
- lateral movement of the doors is not possible, so that the doors can only be pivoted about their pivot axes between the open position and the closed position. If the fixation is released, the carriages and thus also the doors connected to the carriages can be moved in the width direction of the door, ie horizontally, in order to release the largest possible access opening to the receiving space.
- the fixing device can be formed by individual fixing bolts, which in their fixing position interact with corresponding recesses in the carriage.
- the carriages can also have bolts which interact with stationary recesses in the refrigerated cabinet in their fixing positions.
- the upper guide and/or the lower guide are each formed by a guide rail in which the carriages are movably guided in the horizontal direction.
- the carriages are preferably guided in a form-fitting manner in the corresponding guide, whereby the carriages and/or the guides can have sliding sections in order to keep the friction between the carriage and the guide as low as possible.
- Figure 1 shows an embodiment of a refrigerated cabinet 1 according to the invention.
- the refrigerated cabinet basically comprises a ceiling area, two side walls, an in Figure 1 invisible floor area and a rear wall, which is also not visible, connecting the floor area, the ceiling area and the side walls.
- the refrigerated cabinet 1 comprises a plurality of doors 3, each of which is pivotably mounted with the aid of an upper door bearing 11 and a lower door bearing 16.
- the doors 3 are of course transparent (this is not shown in the figures in order to avoid the area behind the doors 3). having to present detail; this would have a negative impact on clarity).
- the refrigerated cabinet 1 now always includes a left and a right edge door 3, ie one door 3 each, which is arranged directly adjacent to one of the two side walls (in Figure 1 the far left and far right doors 3). Furthermore, several middle doors 3 are arranged between the two edge doors 3.
- the doors 3 are now between one in Figure 1 closed position shown (in which the receiving space 2 arranged behind the doors 3 is closed to the outside for the food to be presented, for example on shelves 22) and one in Figure 2 shown open position (in which the receiving space 2 is accessible from the outside) can be pivoted about a vertical pivot axis.
- the doors 3 preferably have handles 19.
- FIG. 1 The comparison of the Figures 1 , 2 and 3 also shows that at least the middle doors 3, in addition to their ability to pivot in the horizontal direction, from an operating position ( Figures 1 and 2 ) into a filling position ( Figure 3 ) can be moved. While the operating position corresponds to the position that the slidably mounted doors 3 normally have during public traffic, so that food can be removed from the refrigerated cabinet 1 for purchase, the filling position primarily serves to easily refill new food by the staff.
- the middle doors 3 are, for. B. via corresponding upper door bearings 11 and lower door bearings 16, each with an upper carriage 6 and a lower carriage 7 in connection. While the upper carriages 6 are guided with the aid of an upper guide 8 (preferably in the form of an upper rail), the lower carriages 7 are guided via a lower guide 9 (preferably in the form of a lower rail).
- the upper guide 8 is preferably located behind one Figure 1 cladding 20 indicated by a reference number, so that it is not or only partially visible in a front view of the refrigerator 1. Likewise, the lower guide 9 can be arranged behind a corresponding panel 20.
- the refrigerated cabinet 1 comprises a plurality of lower carriages 7, which are guided by the lower guide 9, and a plurality of upper carriages 6, which are guided by the upper guide 8.
- the carriages 6, 7 are preferably stored via rollers which engage in corresponding recesses in the guide.
- a sliding guide without rollers is also conceivable.
- two middle doors 3 are connected to a common upper carriage 6 and a common lower carriage 7 and form a pair of doors.
- each rod 4 is preferably arranged between two adjacent doors 3 when viewed from the front of the refrigerated cabinet 1.
- the rod 4 is rotatably connected to the respective carriages 6, 7 via a lower pivot bearing 24 and an upper pivot bearing 23, so that the upper carriage 6 is coupled to the lower carriage 7 of the same pair of doors via the rod 4.
- the rod 4 now has an upper combing element 5 in the upper area and a lower combing element 12 in the lower area, the upper combing element 5 meshing with an upper combing section 13 when the upper carriage 6 moves laterally, i.e. in the horizontal direction, with those attached to it Doors 3 are moved.
- the lower combing element 12 meshes with a lower combing section 14 during the movement of the doors 3 mentioned and thus the lower carriage 7.
- both combing elements 5, 12 always rotate simultaneously and at the same speed when the two carriages 6, 7 of a door 3 or a pair of doors move. Since the upper combing element 5 also meshes with the upper combing section 13 and the lower combing element 12 with the lower combing section 14, it is ensured that the upper carriage 6 and the lower carriage 7 only move at the same time and with the same acceleration or speed relative to the lower guide 9 and to the upper guide 8.
- the axes of rotation of the doors 3 connected to the slides 6, 7 therefore have an exactly vertical orientation in every position and in every phase of the movement. Tilting or tilting of the doors 3 within the guides 8, 9 is therefore impossible at any time, so that smooth and low-wear horizontal movement of the doors 3 is guaranteed.
- both the upper combing element 5 and the lower combing element 12 can be formed by a gear 15.
- the upper combing section 13 and the lower combing section 14 are preferably formed by a link chain 18, each of which extends in the width direction of the refrigerated cabinet 1.
- the link chains 18 are preferably mounted immovably in the width direction of the refrigerated cabinet 1, while in particular the upper link chain 18 can be mounted movably in the vertical direction, so that the upper gear 15 always meshes with the link chain 18 even when the ceiling section of the refrigerated cabinet 1 is lowered.
- the term "combing" means, as usual, that the combing element 5, 12 and the combing section 13, 14 in contact with it during a relative movement between the combing element 5, 12 and the combing section 13, 14 always interlock positively.
- Figures 6 and 7 show Figures 6 and 7 that the upper carriage 6 (the same applies to the lower carriage 7, even if this is not shown) can each have two upper door bearings 11 per door.
- This allows the two doors 3 of a pair of doors to be arranged offset from one another with respect to the door surface 21 visible from the front. This is particularly in Figure 6 clearly visible. If the two doors 3 of an adjacent pair of doors are now arranged correspondingly offset from one another, the two pairs of doors can also be moved relative to one another in the closed position of the doors 3 in such a way that directly adjacent doors 3 overlap at least in sections.
- Figure 9 a preferred embodiment in which the upper combing section 13 is not through a link chain 18, but through a rack 10 is formed.
- the lower combing section 14 can also be formed independently by a toothed rack 10 instead of a link chain 18.
- the respective gear 15 meshes with the rack 10 assigned to it when the carriage 6, 7 connected to the respective gear 15 is moved laterally.
- the lower carriages 7 each have one, preferably two, particularly preferably four, rollers 25, via which they can be moved rollingly along the lower guide(s) 9.
- the lower carriages 7 each have four rollers 25, with two rollers 25 being mounted at a distance from one another on the lower carriage 7 when viewed in the width direction of the refrigerated cabinet.
- a pair of rollers should be arranged in front of the rod 4 and a pair of rollers behind the rod 4, looking from the front of the refrigerated cabinet, in order to ensure an even load distribution on the rollers 25 and thus the lower guide 9.

Description
Die vorliegende Erfindung betrifft ein Kühlmöbel, das der Aufnahme und Präsentation von zu kühlenden Lebensmitteln dient, wobei das Kühlmöbel mehrere Türen und einen Aufnahmeraum für Lebensmittel umfasst, wobei zumindest ein Teil der Türen jeweils in einem oberen Bereich an einem oberen Schlitten und in einem unteren Bereich an einem unteren Schlitten gelagert sind, wobei die Lagerung derart ausgebildet ist, dass die Türen jeweils zwischen einer Offenstellung und einer Schließstellung verschwenkbar sind, wobei der obere Schlitten entlang einer oberen Führung des Kühlmöbels und der unter Schlitten entlang einer unteren Führung des Kühlmöbels verschiebbar gelagert sind, so dass die Türen seitlich bewegbar sind. Gattungsgemäße Kühlmöbel sind im Stand der Technik bekannt und kommen beispielsweise in Supermärkten zum Einsatz, um die zum Verkauf stehenden Lebensmittel dem Kunden zu präsentieren.The present invention relates to a refrigerated cabinet that is used to accommodate and present food to be cooled, the refrigerated cabinet comprising a plurality of doors and a storage space for food, with at least some of the doors each in an upper area on an upper slide and in a lower area are mounted on a lower slide, the storage being designed such that the doors can each be pivoted between an open position and a closed position, the upper slide being mounted so as to be displaceable along an upper guide of the refrigerated cabinet and the lower slide along a lower guide of the refrigerated cabinet , so that the doors can be moved laterally. Generic refrigeration cabinets are known in the art and are used, for example, in supermarkets to present the food for sale to the customer.
Eine bekannte AusfĂĽhrung mit seitlich verschiebbaren SchwenktĂĽren ist beispielsweise in der
Aufgabe der vorliegenden Erfindung ist es, ein entsprechendes Kühlmöbel im Hinblick auf die Führung der Türen bei deren seitlicher Bewegung weiterzubilden.The object of the present invention is to further develop a corresponding refrigerated cabinet with regard to the guidance of the doors during their lateral movement.
Die Aufgabe wird gelöst durch ein Kühlmöbel mit den Merkmalen des unabhängigen Patentanspruchs.The task is solved by a refrigerated cabinet with the features of the independent patent claim.
Das erfindungsgemäße Kühlmöbel umfasst mehrere transparente Türen (z. B. Glastüren, die einfach oder mehrfach verglast sein können), die vorzugsweise rahmenlos ausgebildet sind. Vorzugsweise weisen die Türen eine Mehrfachverglasung auf. Ferner sind die Türen jeweils um eine vertikal verlaufende Schwenkachse zwischen einer Offenstellung und einer Schließstellung verschwenkbar, wobei die Türen in der Schließstellung den Aufnahmeraum nach außen hin verschließen. Befinden sich hingegen eine oder mehrere Türen in ihrer Offenstellung, so gibt die entsprechende Tür einen Zugang in den Aufnahmeraum frei, so dass Lebensmittel aus dem Kühlmöbel entnommen oder in dieses hineingestellt werden können.The refrigerated cabinet according to the invention comprises several transparent doors (e.g. glass doors that can be single or multi-glazed), which are preferably frameless. The doors preferably have one Multiple glazing. Furthermore, the doors can each be pivoted about a vertical pivot axis between an open position and a closed position, with the doors closing the receiving space to the outside in the closed position. However, if one or more doors are in their open position, the corresponding door provides access to the receiving space so that food can be removed from the refrigerator or placed in it.
Ferner sieht die Erfindung nun vor, dass wenigstens ein Teil der Türen darüber hinaus (d. h. neben der genannten Verschwenkbarkeit) entlang einer Führungsanordnung verschiebbar gelagert ist. Die entsprechenden Türen können also um eine Schwenkachse verschwenkt und zusätzlich, vorzugsweise entlang einer linearen Führungsbahn, verschoben werden. Die verschiebbar gelagerten Türen können dabei in eine Richtung verschoben werden, die parallel zu der Vertikalebene verläuft, die durch die Türen gebildet wird, wenn sich diese in ihrer Schließstellung befinden.Furthermore, the invention now provides that at least some of the doors are mounted so as to be displaceable along a guide arrangement (i.e. in addition to the aforementioned pivotability). The corresponding doors can therefore be pivoted about a pivot axis and additionally moved, preferably along a linear guideway. The slidably mounted doors can be moved in a direction that runs parallel to the vertical plane formed by the doors when they are in their closed position.
Die FĂĽhrungsanordnung umfasst eine obere und eine untere FĂĽhrung, so dass die TĂĽren im Bereich ihrer Stirnseiten gefĂĽhrt sind.The guide arrangement includes an upper and a lower guide so that the doors are guided in the area of their end faces.
Vorzugsweise können die verschiebbar gelagerten Türen in der genannten Richtung um einen Betrag verschoben werden, der wenigstens dem 2-fachen, vorzugsweise wenigstens dem 4-fachen der Breite einer der verschiebbar gelagerten Türen beträgt (wobei die Breite die maximale horizontale räumliche Ausdehnung einer Tür darstellt).Preferably, the slidably mounted doors can be moved in the direction mentioned by an amount which is at least 2 times, preferably at least 4 times, the width of one of the slidably mounted doors (the width representing the maximum horizontal spatial extent of a door) .
Ferner ist zumindest ein Teil der Türen jeweils mit einem oberen Schlitten und einem unteren Schlitten verbunden. Erfindungsgemäß ist jede der mit einem Schlitten verbundenen Türen im oberen Bereich über ein oberes Türlager mit einem oberen Schlitten und in einem unteren Bereich über ein unteres Türlager mit einem unteren Schlitten verbunden. Die Türlager sind also Bestandteil der entsprechenden Schlitten. Die Schlitten stehen mit der Führungsanordnung in Kontakt, sind relativ zu diesen verschiebbar und dienen letztendlich der Lagerung der verschiebbar gelagerten Türen gegenüber der Führungsanordnung, wobei der jeweils obere Schlitten mit der oberen Führung und der jeweils unteren Schlitten mit der unteren Führung in Wirkverbindung stehen. Die verschiebbar gelagerten Türen sind somit jeweils gemeinsam mit den mit ihnen verbundenen Schlitten entlang der Führungsanordnung verschiebbar.Furthermore, at least some of the doors are each connected to an upper carriage and a lower carriage. According to the invention, each of the doors connected to a slide is connected to an upper slide in the upper area via an upper door bearing and to a lower slide in a lower area via a lower door bearing. So the door bearings are Part of the corresponding slides. The carriages are in contact with the guide arrangement, are displaceable relative thereto and ultimately serve to support the displaceably mounted doors relative to the guide arrangement, with the upper carriage in each case being in operative connection with the upper guide and the lower carriage in each case with the lower guide. The slidably mounted doors can therefore be moved along the guide arrangement together with the carriages connected to them.
Vorzugsweise stehen die Schlitten direkt mit der Führungsanordnung in Kontakt. Die Schlitten können ferner eine oder mehrere, insbesondere kugelgelagerte, Laufrollen aufweisen, über die sie mit der Führungsanordnung in Kontakt stehen. Die Laufrollen können dabei eine vertikal, horizontal auch schräg zur Horizontalen und/oder Vertikalen verlaufende Drehachse aufweisen. Auch können die Schlitten mehrere Laufrollen mit unterschiedlich ausgerichteten Drehachsen besitzen.The carriages are preferably in direct contact with the guide arrangement. The carriages can also have one or more rollers, in particular with ball bearings, via which they are in contact with the guide arrangement. The rollers can have an axis of rotation that runs vertically, horizontally and obliquely to the horizontal and/or vertical. The carriages can also have several rollers with differently aligned axes of rotation.
Insbesondere ist es von Vorteil, wenn die unteren Schlitten über entsprechende Laufrollen verfügen, über die sie in oder an der unteren Führung geführt sind, während es von Vorteil ist, wenn der obere Schlitten gleitend in der oberen Führung geführt ist.In particular, it is advantageous if the lower carriages have corresponding rollers via which they are guided in or on the lower guide, while it is advantageous if the upper carriage is guided slidably in the upper guide.
Insbesondere ist es von Vorteil, wenn der untere Schlitten eine oder mehrere Laufrollen aufweist, die vorzugsweise eine horizontal ausgerichtete Drehachse aufweist bzw. aufweisen. Die untere Führung kann eine oder mehrere ebene Laufflächen aufweisen, wobei die Führungsrollen der Schlitten jeweils auf der oder einer der Führungsflächen aufliegen und bei einer Bewegung der mit der oder entsprechenden Rolle(n) in Verbindung stehenden Tür rollend entlang der jeweiligen Führungsfläche bewegt werden. Das Gewicht der Türen wird in diesem Fall vor, während und nach der Bewegung der jeweiligen Tür über die Rollen in die Führungsfläche(n) geleitet. Die Türen werden also stets durch die Führungsfläche(n) nach unten hin abgestützt.In particular, it is advantageous if the lower carriage has one or more rollers, which preferably have or have a horizontally oriented axis of rotation. The lower guide can have one or more flat running surfaces, with the guide rollers of the carriage each resting on the or one of the guide surfaces and being moved rollingly along the respective guide surface when the door connected to the corresponding roller(s) moves. In this case, the weight of the doors is transferred via the rollers into the guide surface(s) before, during and after the movement of the respective door. The doors are therefore always supported downwards by the guide surface(s).
Vorzugsweise sind die oberen Türlager der Türen schwimmend ausgebildet, d.h. die Türlager erlauben eine Relativbewegung zwischen den Türen und einem oberhalb der Türen angeordneten Abschnitt des Kühlmöbels (so genannter Kühlmöbelkopf), so dass es bei einem nach einer gewissen Betriebszeit des Kühlmöbels nicht zu verhindernden geringfügigen Absenken des oberen Abschnitts nicht zu einem Verklemmen der Türen kommen kann.The upper door bearings of the doors are preferably designed to be floating, i.e. the door bearings allow a relative movement between the doors and a section of the refrigerated cabinet arranged above the doors (so-called refrigerated cabinet head), so that a slight lowering cannot be prevented after a certain period of operation of the refrigerated cabinet the upper section prevents the doors from jamming.
Es ist also von Vorteil, wenn das ganze Gewicht der einzelnen Türen über die jeweiligen unteren Schlitten an die mit den Schlitten verbundenen Rollen getragen und von diesen an die untere(n) Führung(en) weitergeleitet wird, die wieder mit einem Rahmen des Kühlmöbels verbunden oder durch diesen gebildet wird bzw. werden.It is therefore advantageous if the entire weight of the individual doors is carried via the respective lower slides to the rollers connected to the slides and passed on from them to the lower guide(s), which are again connected to a frame of the refrigerated cabinet or is or will be formed by it.
Das erfindungsgemäße Kühlmöbel hat somit die folgenden Vorteile: durch die Lagerung der Türen über die Türlager können diese auf herkömmliche Weise zwischen der Offenstellung und der Schließstellung verschwenkt werden, so dass Lebensmittel aus dem Kühlmöbel entnommen oder in dieses gestellt werden können. Werden nun der obere Schlitten unter unterer Schlitten einer oder mehrerer Türen entlang der Führungsanordnung verschoben, so kann die Öffnung ins Innere des Kühlmöbels signifikant vergrößert werden. Beispielsweise wäre es denkbar, mehrere benachbarte obere und untere Schlitten gleichzeitig in horizontaler Richtung soweit zu verschieben, dass sich eine Öffnung in den Aufnahmeraum des Kühlmöbels ergibt, dessen Breite dem vielfachen der Breite einer Tür entspricht. Das Kühlmöbel kann auf diese Weise schnell und einfach, beispielsweise mit einer Paletten-Hubvorrichtung mit neuen Paletten bestückt werden, auf denen sich Lebensmittel befinden.The refrigerated cabinet according to the invention therefore has the following advantages: by supporting the doors via the door bearings, they can be pivoted in a conventional manner between the open position and the closed position, so that food can be removed from or placed in the refrigerated cabinet. If the upper carriage is now moved under the lower carriage of one or more doors along the guide arrangement, the opening into the interior of the refrigerated cabinet can be significantly enlarged. For example, it would be conceivable to simultaneously move several adjacent upper and lower slides in the horizontal direction to such an extent that there is an opening in the receiving space of the refrigerated cabinet, the width of which corresponds to many times the width of a door. In this way, the refrigerated cabinet can be quickly and easily filled with new pallets containing food, for example using a pallet lifting device.
Erfindungsgemäß zeichnet sich das Kühlmöbel nun dadurch aus, dass jeweils ein oberer Schlitten und ein unterer Schlitten, die mit derselben Tür in Verbindung stehen, über eine vertikal verlaufende Stange gekoppelt sind.According to the invention, the refrigerated cabinet is characterized by the fact that an upper carriage and a lower carriage, which are connected to the same door, are coupled via a vertically extending rod.
Die Stange erstreckt sich also von dem unteren Schlitten bis zum oberen Schlitten und stellt eine mechanische Kopplung beider Schlitten dar.The rod therefore extends from the lower carriage to the upper carriage and represents a mechanical coupling of both carriages.
Ferner ist vorgesehen, dass die Stange über jeweils ein oberes Drehlager an einem oberen Schlitten und ein unteres Drehlager an einem unteren Schlitten drehbar gelagert ist (wobei es sich bei den genannten Schlitten um Schlitten handelt, die mit derselben Tür in Verbindung stehen). Die Stange umfasst darüber hinaus ein oberes Kämmelement, das mit einem, vorzugsweise ortsfesten, oberen Kämmabschnitt des Kühlmöbels in Wirkverbindung, insbesondere in direktem Kontakt, steht. Ebenso umfasst die Stange ein unteres Kämmelement, das mit einem, vorzugsweise ortsfesten, unteren Kämmabschnitt des Kühlmöbels in Wirkverbindung, insbesondere in direktem Kontakt, steht.Furthermore, it is provided that the rod is rotatably mounted via an upper pivot bearing on an upper carriage and a lower pivot bearing on a lower carriage (the carriages mentioned being carriages that are connected to the same door). The rod also includes an upper combing element which is in operative connection, in particular in direct contact, with a, preferably stationary, upper combing section of the refrigerated cabinet. The rod also comprises a lower combing element which is in operative connection, in particular in direct contact, with a, preferably stationary, lower combing section of the refrigeration cabinet.
Wird nun die Tür, die mit den genannten Schlitten in Verbindung steht, in horizontaler Richtung verschoben, so kämmt das obere Kämmelement mit dem oberen Kämmabschnitt und das untere Kämmelement mit dem unteren Kämmabschnitt. Da die beiden Kämmelemente über die Stange drehfest miteinander in Verbindung stehen, wird sichergestellt, dass die Türen beim seitlichen Verschieben durch das Zusammenspiel der Kämmelemente und der Kämmabschnitte stets kippsicher geführt sind, da die Kämmelemente formschlüssig in die Kämmabschnitte eingreifen.If the door, which is connected to the carriage mentioned, is now moved in the horizontal direction, the upper combing element meshes with the upper combing section and the lower combing element meshes with the lower combing section. Since the two combing elements are connected to one another in a rotationally fixed manner via the rod, it is ensured that the doors are always guided so that they do not tip over when they are moved laterally due to the interaction of the combing elements and the combing sections, since the combing elements engage in a form-fitting manner in the combing sections.
Mit anderen Worten sieht die Erfindung folgendes vor: wenn eine Tür, die mit einem oberen und einem unteren Schlitten in Verbindung steht (wobei die Schlitten über eine entsprechende Stange gekoppelt sind), seitlich verschoben wird, so bewirkt das Zusammenspiel der Kämmelemente mit den Kämmabschnitten eine Drehung der Stange um eine Vertikalachse (die Kämmelemente werden hierbei relativ zu den Kämmabschnitten bewegt, wobei die Kämmelemente und die Kämmabschnitte jeweils formschlüssig in Verbindung stehen). Da jedoch das obere Kämmelement und das untere Kämmelement aufgrund der Kopplung durch die Stange beim Bewegen der Tür und damit der Schlitten stets die gleiche Drehzahl aufweisen, werden der obere Schlitten und der untere Schlitten einer Tür bei deren seitlicher Bewegung zwangsläufig mit gleicher Beschleunigung bzw. Geschwindigkeit und über die gleiche Bewegungstrecke bewegt. Ein Verkanten oder Kippen der Tür während der seitlichen Verschiebung der Tür ist damit ausgeschlossen.In other words, the invention provides the following: when a door, which is connected to an upper and a lower carriage (the carriages being coupled via a corresponding rod), is displaced laterally, the interaction of the combing elements with the combing sections causes a Rotation of the rod about a vertical axis (the combing elements are moved relative to the combing sections, with the combing elements and the combing sections each being positively connected). However, since the upper combing element and the lower combing element always have the same speed due to the coupling by the rod when moving the door and thus the carriage, the upper The carriage and the lower carriage of a door inevitably move with the same acceleration or speed and over the same movement distance when they move sideways. This prevents the door from tilting or tilting while the door is being moved sideways.
Die Erfindung sieht also prinzipiell vor, dass das Kühlmöbel wenigstens eine Tür aufweist, die mit einem oberen Schlitten und einem unteren Schlitten über entsprechende Türlager gekoppelt sind. Ebenso sind der obere Schlitten und der Unterschlitten über eine Stange miteinander verbunden, die über die genannten Drehlager relativ zu den Schlitten verdreht werden können (wobei die Drehlager derart ausgebildet sein sollten, dass die Stange zwar bezüglich der Drehlager um eine Vertikalachse gedreht werden kann, gleichzeitig aber eine axiale Verschiebung der Stange relativ zu den Schlitten ausgeschlossen ist). Wird nun die Tür seitlich, d.h. in horizontaler Richtung, gegenüber der oben genannten Führungsanordnung verschoben, so können sich der obere Schlitten und der untere Schlitten nur gleichzeitig und mit gleichem Geschwindigkeitsprofil seitlich bewegen, da die Kämmelemente mit den Kämmabschnitten kämmen, wobei die Kämmelemente einer Tür über die Stange drehfest miteinander verbunden sind und sich damit nur gleichzeitig und mit identischer Drehzahl drehen können.In principle, the invention therefore provides that the refrigerated cabinet has at least one door, which is coupled to an upper carriage and a lower carriage via corresponding door bearings. Likewise, the upper carriage and the lower carriage are connected to one another via a rod, which can be rotated relative to the carriage via the pivot bearings mentioned (the pivot bearings should be designed in such a way that the rod can be rotated about a vertical axis with respect to the pivot bearings, at the same time but an axial displacement of the rod relative to the carriage is excluded). If the door is now moved laterally, i.e. in the horizontal direction, relative to the above-mentioned guide arrangement, the upper carriage and the lower carriage can only move laterally at the same time and with the same speed profile, since the combing elements mesh with the combing sections, the combing elements of a door are connected to each other in a rotationally fixed manner via the rod and can therefore only rotate at the same time and at the same speed.
Vorteilhaft ist es, wenn das obere Kämmelement und der obere Kämmabschnitt in vertikaler Richtung oberhalb der Türen und/oder das untere Kämmelement und der untere Kämmabschnitt in vertikaler Richtung unterhalb der Türen angeordnet sind. Weder die Kämmelemente noch die Kämmabschnitte befinden sich in diesem Fall im Bereich der Türen, so dass der Blick ins Innere des Kühlmöbels weder durch die Kämmelemente noch durch die Kämmabschnitte gestört wird. Insbesondere sollten der obere Kämmabschnitt und das obere Kämmelement im Wesentlichen in derselben vertikalen Höhe angeordnet sein. Gleiches gilt für das untere Kämmelement und den unteren Kämmabschnitt.It is advantageous if the upper combing element and the upper combing section are arranged in the vertical direction above the doors and/or the lower combing element and the lower combing section are arranged in the vertical direction below the doors. In this case, neither the combing elements nor the combing sections are located in the area of the doors, so that the view into the interior of the refrigerated cabinet is not disturbed by either the combing elements or the combing sections. In particular, the upper combing section and the upper combing element should be arranged at substantially the same vertical height. The same applies to the lower combing element and the lower combing section.
Des Weiteren ist es vorteilhaft, wenn das obere Kämmelement und/oder das untere Kämmelement als Zahnrad ausgebildet sind (vorzugsweise als Zahnrad mit vertikal ausgerichteter Drehachse). Während es auch denkbar ist, dass das obere Kämmelement und/oder das untere Kämmelement jeweils als Rolle ausgebildet sind, die mehrere umfangseitige Vertiefungen aufweist, die mit Erhöhungen des jeweils zugeordneten Kämmabschnitts in Wirkverbindung stehen, ist die Ausbildung als Zahnrad vorteilhaft, da dieses einfach gereinigt werden kann und sehr verschleißbeständig ist.Furthermore, it is advantageous if the upper combing element and/or the lower combing element are designed as a gear (preferably as a gear with a vertically aligned axis of rotation). While it is also conceivable that the upper combing element and/or the lower combing element are each designed as a roller which has a plurality of circumferential depressions which are in operative connection with elevations of the respectively assigned combing section, the design as a gear is advantageous because it can be easily cleaned can be made and is very wear-resistant.
Vorteilhaft ist es, wenn der obere Kämmabschnitt und/oder der untere Kämmabschnitt durch eine Gliederkette gebildet sind. Die Gliederkette ist vergleichbar zu einer Fahrradkette ausgebildet. Insbesondere ist im oberen Bereich des Kühlmöbels eine Gliederkette angeordnet, die den oberen Kämmabschnitt bildet und sich über den oberen Bereich des Kühlmöbels in horizontaler Richtung erstreckt. Ebenso sollte im unteren Bereich des Kühlmöbels eine weitere Gliederkette angeordnet sein, die den unteren Kämmabschnitt bildet. Insbesondere die obere Gliederkette kann über vertikal ausgerichtete Bolzen in vertikaler Richtung beweglich gelagert sein, wobei die Bolzen in entsprechende Bohrungen oder sonstige Vertiefungen eines der Gliederkette vertikal benachbarten Abschnitts des Kühlmöbels eingreifen. Sowohl die einzelnen Bolzen als auch die einzelnen Bohrungen sind jeweils in horizontaler Richtung beabstandet zueinander angeordnet. Senkt sich nun der obere Bereich des Kühlmöbels, an dem die obere Gliederkette gelagert ist, aufgrund von Kaltverformung, so kann sich die Gliederkette in vertikaler Richtung dennoch stets passend zu den oberen Kämmelementen ausrichten. Die oberen Kämmelemente greifen damit stets in die obere Gliederkette ein.It is advantageous if the upper combing section and/or the lower combing section are formed by a link chain. The link chain is designed comparable to a bicycle chain. In particular, a link chain is arranged in the upper region of the refrigerated cabinet, which forms the upper combing section and extends over the upper region of the refrigerated cabinet in a horizontal direction. Likewise, another link chain should be arranged in the lower area of the refrigerator, which forms the lower combing section. In particular, the upper link chain can be movably mounted in the vertical direction via vertically aligned bolts, the bolts engaging in corresponding bores or other recesses in a section of the refrigeration cabinet that is vertically adjacent to the link chain. Both the individual bolts and the individual holes are arranged at a distance from one another in the horizontal direction. If the upper area of the refrigerated cabinet, on which the upper link chain is mounted, sinks due to cold deformation, the link chain can still always align itself in the vertical direction to match the upper combing elements. The upper combing elements therefore always engage with the upper link chain.
Besonders vorteilhaft ist es, wenn der obere Kämmabschnitt und/oder der untere Kämmabschnitt durch eine Zahnstange gebildet ist. Die Zahnstange kann sich über die gesamte Breite, bzw. zumindest 80 % der Breite, des Kühlmöbels erstrecken. Ebenso ist es denkbar, dass sich die Zahnstange aus mehreren horizontal benachbart zueinander angeordneten Zahnstangenabschnitten zusammensetzt. In jedem Fall ist die Zahnstange in vertikaler Richtung derart angeordnet, dass die oberen Kämmelemente der einzelnen oberen Schlitten während der Bewegung der mit den Schlitten verbundenen Türen stets formschlüssig mit der Zahnstange kämmen.It is particularly advantageous if the upper combing section and/or the lower combing section is formed by a toothed rack. The rack can extend over the entire width, or at least 80% of the width, of the refrigerator. It is also conceivable that the rack composed of several rack sections arranged horizontally adjacent to one another. In any case, the rack is arranged in the vertical direction in such a way that the upper combing elements of the individual upper slides always mesh positively with the rack during the movement of the doors connected to the slides.
Vorteile bringt es zudem mit sich, wenn die Zahnstange Zähne mit einer sich in vertikaler Richtung erstreckenden ersten Höhe aufweist, dass die Zahnräder Zähne mit einer sich in vertikaler Richtung erstreckenden zweiten Höhe aufweist, und dass die erste Höhe wenigstens den doppelten, vorzugsweise den fünffachen, Betrag aufweist wie die zweite Höhe. Auch hierdurch wird sichergestellt, dass die Kämmelemente bei der Bewegung der mit den Kämmelementen über die Stange verbundenen Tür auch dann noch zuverlässig mit der entsprechenden Zahnstange kämmen, wenn sich der Deckenbereich des Kühlmöbels, an dem die Zahnstange direkt oder indirekt befestigt ist, über die Zeit geringfügig nach unten senkt. Die genannten Höhenangaben beziehen sich vorzugsweise auf die im oberen Bereich des Kühlmöbels angeordnete Zahnstange. Die im unteren Bereich angeordnete Zahnstange, die den unteren Kämmabschnitt bildet, kann hingegen eine Höhe aufweisen, die geringer ist als die Höhe der oberen Zahnstange, da sich der untere Bereich des Kühlmöbels in der Regel nicht absenkt.There are also advantages when the rack has teeth with a first height extending in the vertical direction, that the gears have teeth with a second height extending in the vertical direction, and that the first height is at least twice, preferably five times, The amount has the same as the second height. This also ensures that the combing elements still reliably comb with the corresponding rack when the door connected to the combing elements via the rod moves, even if the ceiling area of the refrigerator to which the rack is directly or indirectly attached changes over time lowered slightly. The height information mentioned preferably refers to the rack arranged in the upper area of the refrigerator. The rack arranged in the lower region, which forms the lower combing section, can, however, have a height that is lower than the height of the upper rack, since the lower region of the refrigerated cabinet generally does not lower.
Des Weiteren ist es vorteilhaft, wenn der obere Kämmabschnitt und/oder der untere Kämmabschnitt hinter einer Verkleidung angeordnet sind, so dass der obere Kämmabschnitt und/oder der untere Kämmabschnitt von außerhalb des Kühlmöbels und mit Blick von vorne auf die Türen nicht sichtbar sind. Die entsprechende Verkleidung erstreckt sich vorzugsweise über die gesamte Breite des jeweiligen Kämmabschnitts. Vorzugsweise umgreift eine obere Verkleidung den oberen Kämmabschnitt von oben. Ebenso sollte eine untere Verkleidung den unteren Kämmabschnitt von unten bzw. von vorne (mit Blick auf das Kühlmöbel) umgreifen.Furthermore, it is advantageous if the upper combing section and/or the lower combing section are arranged behind a panel, so that the upper combing section and/or the lower combing section are not visible from outside the refrigerated cabinet and when looking at the doors from the front. The corresponding covering preferably extends over the entire width of the respective combing section. Preferably, an upper panel surrounds the upper combing section from above. Likewise, a lower panel should surround the lower combing section from below or from the front (facing the refrigerator).
Vorteile bringt es zudem mit sich, wenn sich der obere Kämmabschnitt und/oder der untere Kämmabschnitt über wenigstens 30 %, vorzugsweise über wenigstens 80 %, der Breite des Kühlmöbels erstreckt. Insbesondere sollte sowohl der obere Kämmabschnitt als auch der untere Kämmabschnitt bezogen auf die Breite des Kühlmöbels mittig ausgerichtet sein. Die entsprechenden Kämmabschnitte müssen sich prinzipiell nicht über die gesamte Breite des Kühlmöbels erstrecken, da die jeweils äußeren Türen des Kühlmöbels nicht zwangsläufig über entsprechende Schlitten gelagert sein müssen.There are also advantages if the upper combing section and/or the lower combing section extends over at least 30%, preferably over at least 80%, of the width of the refrigerated cabinet. In particular, both the upper combing section and the lower combing section should be centrally aligned with respect to the width of the refrigerator. In principle, the corresponding combing sections do not have to extend over the entire width of the refrigerated cabinet, since the outer doors of the refrigerated cabinet do not necessarily have to be supported on corresponding slides.
Auch ist es vorgesehen, dass jeweils zwei Türen ein Türenpaar bilden, wobei die Türen eines Türenpaars jeweils an einem gemeinsamen oberen Schlitten und einem gemeinsamen unteren Schlitten gelagert sind. Die Türen sind damit nicht unabhängig voneinander einzeln verschiebbar. Vielmehr ist jeweils ein Türenpaar (d.h. zwei direkt benachbarte Türen) mit jeweils einem gemeinsamen oberen Schlitten und mit einem gemeinsamen unteren Schlitten verbunden, wobei die genannten Schlitten wiederum über die oben beschriebene Stange miteinander gekoppelt sind.It is also provided that two doors each form a pair of doors, with the doors of a pair of doors each being mounted on a common upper carriage and a common lower carriage. The doors cannot therefore be moved independently of each other. Rather, a pair of doors (i.e. two directly adjacent doors) are each connected to a common upper carriage and to a common lower carriage, the said carriages in turn being coupled to one another via the rod described above.
Insbesondere ist es von Vorteil, wenn die Stange mit Blick auf die Türen in horizontaler Richtung mittig zwischen den zwei Türen eines Türenpaars angeordnet ist. Die Stange erstreckt sich hierbei im Bereich zweier gegenüberliegender Seitenabschnitte der Türen des entsprechenden Türenpaars. Vorzugsweise hat die Stange einen Durchmesser, der zwischen 0,5 cm und 2 cm liegt, so dass der Blick in das Innere des Kühlmöbels nur minimal beeinträchtigt wird. Insbesondere sollte die Stange aus Metall gefertigt sein. Denkbar ist jedoch auch, dass die Stange aus einem transparenten Material, beispielsweise aus Glas oder Plexiglas, gefertigt ist, so dass die Stange den Blick ins Innere des Kühlmöbels so gut wie gar nicht beeinträchtigt.It is particularly advantageous if the rod is arranged horizontally in the middle between the two doors of a pair of doors with a view of the doors. The rod extends in the area of two opposite side sections of the doors of the corresponding pair of doors. The rod preferably has a diameter that is between 0.5 cm and 2 cm, so that the view into the interior of the refrigerator is only minimally impaired. In particular, the rod should be made of metal. However, it is also conceivable that the rod is made of a transparent material, for example glass or Plexiglas, so that the rod hardly impairs the view inside the refrigerator.
Besonders vorteilhaft ist es, wenn die Türen jeweils eine in der Schließstellung dem Aufnahmeraum abgewandte Türoberfläche aufweisen (die Türoberfläche wird durch die dem Kunden zugewandte Oberfläche der Tür gebildet), wobei die Türoberflächen der Türen eines ersten Türenpaares in deren Schließstellung in einer ersten Vertikalebene liegen. Ferner sollten die Türoberflächen der Türen eines, dem ersten Türenpaar direkt benachbarten, zweiten Türenpaares in deren Schließstellung in einer zweiten Vertikalebene liegen. Von Vorteil ist es nun, wenn die erste Vertikalebene und die zweite Vertikalebene parallel zueinander verlaufen und in einer normal zu den Vertikalebenen verlaufenden Richtung um einen Betrag zueinander beabstandet sind, der wenigstens der normal zu den Vertikalebenen verlaufenden Dicke der Türen entspricht. Hierdurch ist es möglich, dass das erste Türenpaar und das zweite Türenpaar derart zueinander verschiebbar sind, dass sich eine Tür des ersten Türenpaars und eine Tür des zweiten Türenpaars zumindest teilweise überlappen, wenn sich die genannten Türen in ihrer Schließstellung befinden. Zwei benachbarte Türenpaare können hierdurch auch dann in horizontaler Richtung aufeinander zu bewegt werden, wenn die Türen ihre Schließstellung aufweisen.It is particularly advantageous if the doors each have a door surface facing away from the receiving space in the closed position (the door surface is formed by the surface of the door facing the customer), the door surfaces of the doors of a first pair of doors lying in a first vertical plane in their closed position. Furthermore, the door surfaces of the doors of a second pair of doors directly adjacent to the first pair of doors should lie in a second vertical plane in their closed position. It is now advantageous if the first vertical plane and the second vertical plane run parallel to one another and are spaced apart from one another in a direction normal to the vertical planes by an amount which corresponds at least to the thickness of the doors normal to the vertical planes. This makes it possible for the first pair of doors and the second pair of doors to be displaceable relative to one another in such a way that a door of the first pair of doors and a door of the second pair of doors at least partially overlap when the doors mentioned are in their closed position. This means that two adjacent pairs of doors can be moved towards each other in a horizontal direction even when the doors are in their closed position.
Der gleiche Effekt kann dadurch realisiert werden, wenn jeweils eine erste Tür eines Türenpaares in der ersten Vertikalebene und die zweite Tür des entsprechenden Türenpaares in der zweiten Vertikalebene angeordnet sind, wenn sich die beiden Türen in ihrer Schließstellung befinden. Benachbarte Türen sind in diesem Fall vorzugsweise abwechselnd in der ersten vertikalen Ebene und der zweiten vertikalen Ebene angeordnet. Mit anderen Worten: es ist vorteilhaft, wenn in Breitenrichtung des Kühlmöbels gesehen die einzelnen Türen des Kühlmöbels abwechselnd vor und hinter einer gemeinsamen Vertikalebene angeordnet sind.The same effect can be achieved if a first door of a pair of doors is arranged in the first vertical plane and the second door of the corresponding pair of doors is arranged in the second vertical plane when the two doors are in their closed position. In this case, adjacent doors are preferably arranged alternately in the first vertical plane and the second vertical plane. In other words: it is advantageous if, viewed in the width direction of the refrigerator, the individual doors of the refrigerator are arranged alternately in front of and behind a common vertical plane.
An dieser Stelle sei allgemein darauf hingewiesen, dass es von Vorteil ist, wenn die oberen Schlitten und/oder die unteren Schlitten mit Hilfe einer Fixiereinrichtung gegenüber der oberen und/oder der unteren Führung ortsfest fixiert werden können. Nach der Fixierung der Schlitten ist eine seitliche Bewegung der Türen nicht möglich, so dass die Türen lediglich um ihre Schwenkachsen zwischen der Offenstellung und der Schließstellung verschwenkt werden können. Wird die Fixierung gelöst, so können die Schlitten und damit auch die mit den Schlitten verbundenen Türen in Breitenrichtung der Tür, d.h. horizontal, verschoben werden, um eine möglichst große Zugangsöffnung zum Aufnahmeraum freizugeben. Die Fixiereinrichtung kann durch einzelne Fixierbolzen gebildet werden, die in ihrer Fixierstellung mit entsprechenden Vertiefungen in den Schlitten zusammenwirken. Ebenso können die Schlitten Bolzen aufweisen, die in ihrer Fixierstellungen mit ortsfesten Vertiefungen des Kühlmöbels zusammenwirken.At this point it should be generally pointed out that it is advantageous if the upper carriage and/or the lower carriage are stationary relative to the upper and/or the lower guide with the aid of a fixing device can be fixed. After the carriages have been fixed, lateral movement of the doors is not possible, so that the doors can only be pivoted about their pivot axes between the open position and the closed position. If the fixation is released, the carriages and thus also the doors connected to the carriages can be moved in the width direction of the door, ie horizontally, in order to release the largest possible access opening to the receiving space. The fixing device can be formed by individual fixing bolts, which in their fixing position interact with corresponding recesses in the carriage. The carriages can also have bolts which interact with stationary recesses in the refrigerated cabinet in their fixing positions.
Des Weiteren ist es vorteilhaft, wenn die obere Führung und/oder die untere Führung jeweils durch eine Führungsschiene gebildet sind, in der die Schlitten in horizontaler Richtung beweglich geführt sind. Die Schlitten sind vorzugsweise formschlüssig in der entsprechenden Führung geführt, wobei die Schlitten und/oder die Führungen Gleitabschnitte aufweisen können, um die Reibung zwischen Schlitten und Führung möglichst gering zu halten.Furthermore, it is advantageous if the upper guide and/or the lower guide are each formed by a guide rail in which the carriages are movably guided in the horizontal direction. The carriages are preferably guided in a form-fitting manner in the corresponding guide, whereby the carriages and/or the guides can have sliding sections in order to keep the friction between the carriage and the guide as low as possible.

Vorab sei darauf hingewiesen, dass nicht alle gleichartigen Abschnitte (z. B. die oberen Schlitten 6 und die unteren Schlitten 7 oder die unteren Türlager 16 und die oberen Türlager 11) in allen Figuren durchgehend mit Bezugszeichen versehen sind, um eine bessere Übersichtlichkeit zu gewährleisten. Bei gleich gezeichneten Abschnitten bzw. Elementen handelt sich jedoch stets um gleiche Abschnitte bzw. gleiche Elemente.It should be noted in advance that not all similar sections (e.g. the
Ferner umfasst das Kühlmöbel 1 mehrere jeweils mit Hilfe eines oberen Türlagers 11 und eines unteren Türlagers 16 schwenkbar gelagerte Türen 3. Die Türen 3 sind selbstverständlich transparent ausgebildet (in den Figuren ist dies nicht dargestellt, um den hinter den Türen 3 liegenden Bereich nicht im Detail darstellen zu müssen; dies hätte eine negative Beeinträchtigung der Übersichtlichkeit zur Folge).Furthermore, the
Generell umfasst das Kühlmöbel 1 nun stets eine linke und eine rechte randseitige Tür 3, d. h. jeweils eine Tür 3, die unmittelbar einer der beiden Seitenwände benachbart angeordnet ist (in

Insbesondere ist es in diesem Zusammenhang von Vorteil, wenn sich zwischen dem Deckenbereich und dem Bodenbereich im Bereich zwischen den Seitenwänden keine tragenden Pfosten befinden, so dass nahezu die gesamte Breite des Aufnahmeraums 2 von außen zugänglich ist, sobald die mittleren Türen 3 ihre Befüllposition eingenommen haben.In particular, it is advantageous in this context if there are no supporting posts between the ceiling area and the floor area in the area between the side walls, so that almost the entire width of the receiving
Um nun ein Verschieben der mittleren Türen 3 zu ermöglichen, stehen diese, z. B. über entsprechende obere Türlager 11 und untere Türlager 16, mit jeweils einem oberen Schlitten 6 und einem unteren Schlitten 7 in Verbindung. Während die oberen Schlitten 6 mit Hilfe einer oberen Führung 8 (vorzugsweise in Form einer oberen Schiene) geführt sind, sind die unteren Schlitten 7 über eine untere Führung 9 (vorzugsweise in Form einer unteren Schiene) geführt. Die obere Führung 8 befindet sich vorzugsweise hinter einer lediglich in
In jedem Fall umfasst das Kühlmöbel 1 mehrere untere Schlitten 7, die durch die untere Führung 9 geführt sind und mehrere obere Schlitten 6, die durch die obere Führung 8 geführt sind. Die Lagerung der Schlitten 6, 7 erfolgt vorzugsweise über Laufrollen, die in entsprechende Vertiefungen der Führung eingreifen. Denkbar ist ebenso eine Gleitführung ohne Laufrollen.In any case, the
Erfindungsgemäß stehen jeweils zwei mittlere Türen 3 mit einem gemeinsamen oberen Schlitten 6 und einem gemeinsamen unteren Schlitten 7 in Verbindung und bilden hierbei ein Türenpaar.According to the invention, two
Um nun sicherzustellen, dass der einer bzw. zwei benachbarten Tür(en) 3 zugeordnete obere Schlitten 6 und der derselben bzw. denselben Tür(en) 3 zugeordnete untere Schlitten 7 stets gleichzeitig und hierbei gleich schnell verschoben werden, sind jeweils ein oberer Schlitten 6 und ein unterer Schlitten 7 mit einer Stange 4 verbunden. Eine derartige Lösung ist unter anderem in den
Wie den genannten Figuren zu entnehmen ist, ist jede Stange 4 mit Blick von vorne auf das Kühlmöbel 1 vorzugsweise zwischen zwei benachbarten Türen 3 angeordnet. Die Stange 4 ist über ein unteres Drehlager 24 und ein oberes Drehlager 23 gegenüber den jeweiligen Schlitten 6, 7 drehbar mit diesen verbunden, so dass der obere Schlitten 6 mit dem unteren Schlitten 7 desselben Türenpaares über die Stange 4 gekoppelt ist.As can be seen from the figures mentioned, each
Die Stange 4 weist nun im oberen Bereich ein oberes Kämmelement 5 und im unteren Bereich ein unteres Kämmelement 12 auf, wobei das obere Kämmelement 5 mit einem oberen Kämmabschnitt 13 kämmt, wenn der obere Schlitten 6 seitlich, d.h. in horizontaler Richtung, mit den daran befestigten Türen 3 verschoben wird. Gleichzeitig kämmt das untere Kämmelement 12 mit einem unteren Kämmabschnitt 14 während der Bewegung der genannten Türen 3 und damit des unteren Schlittens 7.The
Weil das obere Kämmelement 5 und das untere Kämmelement 12 drehfest mit der Stange 4 verbunden sind, drehen sich beide Kämmelemente 5, 12 bei der Bewegung der beiden Schlitten 6, 7 einer Tür 3 bzw. eines Türenpaares stets gleichzeitig und mit gleicher Drehzahl. Da das obere Kämmelement 5 hierbei darüber hinaus mit dem oberen Kämmabschnitt 13 und das untere Kämmelement 12 mit dem unteren Kämmabschnitt 14 kämmt, ist sichergestellt, dass sich der obere Schlitten 6 und der untere Schlitten 7 nur gleichzeitig und mit gleicher Beschleunigung bzw. Geschwindigkeit relativ zur unteren Führung 9 und zur oberen Führung 8 bewegen lassen. Die Drehachsen der mit den Schlitten 6, 7 verbundenen Türen 3 weisen damit in jeder Stellung und in jeder Phase der Bewegung eine exakt vertikale Ausrichtung auf. Ein Verkippen oder Verkanten der Türen 3 innerhalb der Führungen 8, 9 ist damit zu jeder Zeit ausgeschlossen, so dass eine leichtgängige und verschleißarme horizontale Bewegung der Türen 3 gewährleistet ist.Because the upper combing
Eine mögliche Ausbildung der Kämmelemente 5, 12 sowie der Kämmabschnitte 13, 14 ist der Zusammenschau der
Wie diese Figuren zeigen, können sowohl das obere Kämmelement 5 als auch das untere Kämmelement 12 durch ein Zahnrad 15 gebildet sein. Hingegen wird der obere Kämmabschnitt 13 und der untere Kämmabschnitt 14 vorzugsweise durch eine Gliederkette 18 gebildet, die sich jeweils in Breitenrichtung des Kühlmöbels 1 erstrecken.As these figures show, both the upper combing
Die Gliederketten 18 sind in Breitenrichtung des Kühlmöbels 1 vorzugsweise unbeweglich gelagert, während insbesondere die obere Gliederkette 18 in vertikaler Richtung beweglich gelagert sein kann, so dass das obere Zahnrad 15 auch bei einem Absenken des Deckensabschnitts des Kühlmöbels 1 stets mit der Gliederkette 18 kämmt.The
Im Übrigen sei an dieser Stelle allgemein für die Erfindung darauf hingewiesen, dass der Begriff "kämmen" wie üblich bedeutet, dass das Kämmelement 5, 12 und der mit ihm in Kontakt stehende Kämmabschnitt 13, 14 bei einer Relativbewegung zwischen Kämmelement 5, 12 und Kämmabschnitt 13, 14 stets formschlüssig ineinandergreifen.Furthermore, it should be noted at this point in general terms for the invention that the term "combing" means, as usual, that the combing
