Description

The The invention relates to a demountable into main assemblies and modular designed cooling shelf kit, which in particular for commercial use in the food retail trade for example Meat vegetables, Fruit or dairy products is provided.

Display Cases are known as factory assembled complete modules in different (standardized) dimensions, for example in lengths to 1875 mm, 2500 mm and 3750 mm and heights to 2040 mm and 2200 mm. These complete modules have considerable transport and space requirements. They are standing on a transport floor and will transported completely assembled. They can be, however, only by means of Bring a forklift or pallet truck to the store or supermarket. Their transport is very expensive due to the high space requirements. The disadvantage is still a fault the sales process when introducing the complete modules. The subsequent exchange existing old equipment with an average life of 7 years is in furnished business premises only with enormous effort to accomplish. The expansion of shop windows, Door systems, entire rows of racks and the transport of these large equipment via escalators in basement floors and long-lasting disruptions of business operations while Such remodeling and renovation work is often unavoidable.

EP 0 722 685 B1 describes a collapsible refrigerator, which is based on a frame part with refrigerated foot assembly. In this solution, instead of a self-supporting base body, a pedestal is rigidly connected to a stand via at least one rigid connection group. The connection group serves in particular to avoid thermal bridges.

In EP 0 639 948 B1 dismountable refrigerated cabinets are described in which an additional casing made of a cardboard-based material is provided around the actual refrigeration unit. This solution is extremely problematic in terms of refrigeration, since refrigeration units must be constantly defrosted, so that penetrating moisture causes great problems.

The kit for refrigerated cabinets according to DE 24 46 135 A1 based on cutable insulating panels. When cutting the sandwich panels, outer container and inner container panels can be separated from the PU foam. Thus, moisture can penetrate into the insulation, which leads to significant problems in the event of icing. When joining the elements, cold bridges can occur.

task The invention is the development of a decomposable into main assemblies and modular designed in different dimensions combinable Cooling rack kit. The modules are in particular a good stackability and storage, a enable effective transport and easy assembly, the self of in the refrigerator furniture assembly untrained Persons is functionally possible.

The cooled Air can be supplied from a central chiller. A separate refrigeration condensing unit can also be integrated directly into the floor module become. In the arrangement of several cooling rack kits may be in one or in several of the floor modules a refrigeration unit for all or a part of the refrigerated shelves are located. Directly under the floor pan is an adjustable Pedestal. All parts of the floor module are packed completely pre-assembled and transported.

The Backplane module consists of one or more insulated back panels and an air deflector, which are mounted so that forms an air channel in between becomes. In the air guide wall there are several air outlet openings. At the back the baffle can additional Air guide plates to the fluidic Optimization can be arranged.

The ceiling module consists of an insulated form ceiling and a turn spaced air duct part. These parts are again attached to each other as before, that between them an air duct is formed. In the air guide part there are air outlet openings for the supplied cooled air. These air outlet openings may be simple slots or these slots are filled for fluidic optimization with additional honeycomb elements, perforated plates or lamellae guides, which can evenly distribute the cold air and / or conduct. The ceiling modules can optionally with Rolloeinschü ben and / or lighting cassettes are completed.

The stand module consists of at least two upright profiles, which can be attached to the floor module and where the rear wall module and the ceiling module can be attached. Usually, the stand modules U-shaped profiles, in which the backplane modules supporting areas openings for attachable support parts are located. On the support parts are then in variable heights the shelves for the attached goods to be exported.

All outer parts of the cooling rack kit, so the floor pan, the back wall parts, the mold cover and the side wall are double-walled, with in the interstices the sheet metal insulation materials be introduced. These can be PU foam, PU foam sheets, insulating wool or other usual ones Be materials.

The Four main assemblies are packed and transported separately. On site, the customer can assemble the modules themselves. A form and / or frictional Connection of the individual main modules takes place via detachable eccentrics or snap and clamping elements. They form over appropriate seals a diffusion-tight connection and thus a self-supporting Total body. At the lateral conclusion of the Kühlregalbausatzes are respectively isolated side walls attached.

By The modular modular system is a range of refrigerated cabinets at different depths or heights Can be combined with each other, where the tub depth of the floor module should be coordinated with the ceiling depth of the ceiling module and the height of the refrigerated shelf be adjusted by different high parts of the backplane module can. The theoretically endless alignability is possible as well a graduation with different sidewall types. The modular packaging allows one effective shipping and flexibility in storage and design on site. The solution gives the steady global expansion of the retail chains the possibility the desired Flexibility.

The Volume to be transported is reduced in the kit variant according to the invention to about half compared to a ready-built shelf. Through the packaging of the entire shelf in four boxes is such a refrigerated shelf too transportable with a smaller vehicle, with two men from Hand dismountable and easy to build later in a fully furnished retail store.

The stackability and combinability of the kit shelf also allows smaller refrigeration furniture dealers for the first time a storage and thus fast response to customer requests. The Reduction of customer-specific color and shape parts of the kit on the head and base allows easy retrofitting with shades any retail chains and design adjustments by subsequent assembly Rammschutzleisten, trim strips, etc.
