Description

The invention relates to a commercial refrigerated shelf with a front accessible refrigerator.

Commercial refrigerators are used to store foods that need to be kept cool. In the present case, a refrigerated shelf is understood to mean both a refrigerated shelf for refrigeration temperatures above 0 ° C. and refrigeration temperatures below 0 ° C. The refrigerator can be divided by vertically stacked shelves in individual separate compartments. For removal and filling with food, the cooling shelf has an access opening lying in a vertical plane.

Such refrigerated shelves are known from the prior art, both with door-free access opening and with an access opening, which is closed by hinged doors that can be swung open for goods removal and for goods loading. The use of arranged in the access opening revolving doors allows energy-efficient storage of food. However, the revolving doors interfere during peak hours, which can negatively impact food sales. Even with intensive goods loading, maintenance or cooling rack cleaning, the revolving doors can be annoying.

Out EP 2 345 347 A1 is a cooling rack is known in which the swing doors can be moved from their position of use in the access opening, if necessary, in a storage position within the refrigerator shelf cooling space. However, this reduces the commercially usable cold room within the refrigerator shelf, which can be used for the storage of food.

Out WO 2012/041460 A1 is a cooling rack is known which has a plurality of revolving doors, which can be pushed together in its opening position in the access opening of the refrigerated shelf in a package.

Out DE 19620045 C1 a rail system for wall elements is known which allows to pack the wall elements in a storage position.

The object of the invention is in contrast to provide a cooling rack, which allows to operate the cooling rack flexible and energy-efficient, without reducing the commercially usable refrigerator for this purpose.

This object is achieved according to the invention with the features of patent claim 1.

The refrigerated shelf according to the invention has an upper horizontal support rail, which is attached to the upper side edge of the access opening to the shelf body, and has a lower horizontal support rail, which is attached to the lower side edge of the access opening to the shelf body of the refrigerated shelf. The two mounting rails span between the access opening, which lies in a vertical plane. The support rails have a profile that carries and guides correspondingly formed rotor elements, which in turn hold door carriages to each of which a revolving door is attached.

The revolving doors are hinged doors, which are rotatably mounted via respective hinges on an upper and / or a lower door carriage. The revolving doors preferably have a transparent door pane, which can be made of glass or plastic. The revolving doors are thus each held rotatably by a lower and / or upper door carriage. The door slide are in turn mounted horizontally displaceable on the support rails on the runners.

The rotor elements may have rolling elements or wheels to allow a smooth running, but may also be designed as sliding elements that form a low-resistance sliding material pairing with the shelf body support rails.

According to the invention, a door storage is arranged laterally of the shelf body, that is outside of the cold room, which is enclosed by the shelf body, wherein the door storage has an upper and a lower storage rail arrangement, which connects in each case to the corresponding upper and lower support rail of the shelf body. The door storage has storage rails that are similar or identical in cross section to the support rails on the shelf body. The door slide the revolving doors can therefore not only be moved to the mounting rails, but can also be moved into or in the memory rails of the memory rail arrangement.

All revolving doors of the cooling rack are in their use position next to each other in the access opening, so are all in a single vertical plane of the access opening. If the access opening is to be fully opened, the revolving doors are successively pushed over the mounting rails in the storage rail arrangement in which the revolving doors are stored standing behind each other. In their storage position, the revolving doors are thus packet-like and parallel to each other in several offended vertical planes.

Since the revolving doors are no longer stored in their storage position within the shelf shelf, the entire interior of the refrigerator is available as a cold storage room for food. The door storage can be designed so that its front through a Goods shelf is completed, so that the revolving doors are hidden behind invisible.

Preferably, the storage rail arrangement has two upper and / or two lower horizontal storage rails, which are arranged at approximately 90 ° to the support rails. The door slides are displaceable on the storage rails in the depth direction, so that the door slides can be moved in this way in the depth direction to its storage position. The door slide a revolving door are thus first pushed from the support rails of the shelf body in a the shelf body support rail continuing door storage support rail, branch off from each of two lower memory rails or two upper memory rails vertically in the depth direction. As soon as the upper and lower door carriages of the revolving door are completely inserted into the door storage support rail, the direction of movement of the revolving door changes by 90 °, and the revolving door is inserted into the two upper and two lower storage rails, and thus in their storage position brought. Subsequently, the following revolving door is brought in this way in the door storage and inserted in the depth direction. In this way, a revolving door package is assembled in the door storage.

According to an alternative embodiment, the storage rail arrangement has a plurality of upper and / or a plurality of lower storage rails, which are arranged in parallel to the carrier rails and staggered in the depth direction one behind the other and are jointly displaceable in the depth direction. All storage rails are and therefore always remain parallel to the shelf body mounting rails. The storage rails are approximately the width of a revolving door. For each revolving door, an upper or a lower storage rail is provided, wherein the storage rails are arranged for a revolving door parallel to each other in a vertical plane. The storage rails thus each form a storage rail package that can only be moved as a whole in the depth direction. The storage bar package is preferably rigid.

To be able to push a revolving door into a respective storage rail, the relevant storage rail must be moved in the depth direction and aligned in this way with the shelf body support rail in parallel alignment. As soon as the relevant revolving door is inserted into this storage rail, the storage rail package is displaced in the depth direction such that a further free storage rail is aligned with the shelf body mounting rail. In the free storage rail then the next revolving door can be inserted. If necessary, this process is repeated until all the revolving doors are pushed into the associated memory rails of the door storage and stored in this way in their storage position. Finally, the entire storage rail package including the revolving doors can be moved in the depth direction in the parking position of the storage rails.

Preferably, or alternatively, the door storage on a chain drive, which carries and moves all the storage rails of a plane. The chain drive can be driven manually or by electric motor. The storage rails of a plane are therefore not rigid, but are hinged together. In this way it can be avoided that storage rails protrude far forward beyond the vertical plane of the access opening out of the door storage to insert the first revolving door in the rearmost storage rails. The chain drive for the upper storage rails and the lower storage rails is preferably coupled to each other electrically, electronically or mechanically, so that it is ensured that the revolving doors in the storage rails are always in a horizontal plane. That way Tensions and tilting of the door slide or the rotor elements avoided.

According to a preferred embodiment, the upper and / or the lower door carriages each have a locking bolt which fixes the revolving door in its closed position on the door carriage in its locking position and releases the revolving door in its use position, so that the revolving door is opened in rotation about its vertical axis of rotation can. The locking bolt thus increases the safety of operation, since the revolving door can only be opened when the relevant door carriage is fixed to the support rail through the locking bolt.

Preferably, the upper and / or the lower door carriages each have a Schließkontroil mechanism which is designed such that a revolving door in the closed position opens a safety latch which forcibly fixes the door slide on the mounting rail with the revolving door open. This ensures that even when the revolving door is open or wide, a locking of the door carriage on the mounting rail can not be solved. This increases operating safety.

Preferably, each door slide on a closed position stop on which the revolving door abuts in its closed position. In this way, when the revolving door is closed, a great overall stability of the revolving door is ensured in relation to the door carriages, so that the revolving door can not be tilted or rotated in relation to the mounting rail.
