Definitions

  • the invention relates to a refrigerated display cabinet with an upper goods space designed as a shelf structure, with a lower goods space preferred in front of the shelf structure and with two side walls which are arranged perpendicular to the front side facing the customer.
  • Such furniture often referred to as refrigerated shelves, is generally used for the storage and presentation of perishable goods that are offered for sale. For example, they are installed in retail outlets in the food industry and often contain dairy products or other perishable products.
  • the lower goods area can be designed, for example, as a chest; however, sometimes a front boundary wall is completely dispensed with.
  • Such furniture usually also has a ceiling part from which cooling air exits in order to form a vertical veil in front of the shelf structure.
  • a lighting device is often also installed on the ceiling part.
  • the ceiling part is generally extended forward, i.e. its depth is roughly equal to the depth of the lower goods area and thus also depends on the special design variant.
  • the ceiling part is also generally covered laterally, so that the entire side wall is given approximately the shape of a letter U rotated by 90 °. The same problems occur with the upper branch of the U, the side cover of the front cover part, as with that of the front area of the lower goods area.
  • the invention is therefore based on the object of developing a refrigerated display cabinet of the type mentioned at the outset which allows flexible design and is inexpensive to manufacture.
  • At least one side wall has a main module and at least one auxiliary module which is connected to the main module, the main module laterally delimiting the shelf structure and the auxiliary module the front area of the goods area.
  • the modular structure according to the invention initially appears to be problematic, since the most important task of the side walls is to protect the goods area against the entry of heat. This is made more difficult by a connection such as the side wall in the invention. However, it has been shown that the advantages of the construction according to the invention far outweigh the higher costs for the insulation.
  • the dimensions of the display case are mainly determined by the height and depth of the shelf structure on the one hand and the course of the cooling air curtain on the front of the shelves on the other.
  • the dimensions of the shelf structure are the same for the different versions of the refrigerated display cabinet. They are essentially determined by the average human body size to ensure that the goods stored on the shelf are also accessible to the majority of customers.
  • the main module provided in the invention for the lateral covering of the shelf structure can thus be shaped independently of the special design in the front area of the refrigerated display cabinet. In the manufacture of the cooling shelf according to the invention, a considerable part of the costs can be saved in that the main module can be produced inexpensively and in a time-saving manner as a series product which is of the same design in all furniture variants.
  • the front part of the piece of furniture can have different dimensions in its cross section. This applies in particular to the depth of the lower goods area and thus the position of the cooling air curtain and the height and shape of the front section of the goods area.
  • the side wall according to the invention has auxiliary modules which, however, only have to cover a much smaller area than the first component. In the refrigerated display cabinet according to the invention, it is now sufficient to adapt this relatively small part of the side wall to the special profile of the lower goods compartment of the respectively desired variant.
  • the side wall or the side walls have a lower auxiliary module which laterally delimits the lower goods area in its front area.
  • the side wall or the side walls alternatively or additionally have an upper auxiliary module which laterally delimits the shelf structure in its front ceiling area. Both branches of the U-shape of the side wall can thus be formed by the two smaller auxiliary modules.
  • Cooling shelves with an extended ceiling section are often equipped with a side window made of glass or transparent plastic material in addition to the solid, usually heat-insulating side wall. This improves the air flow on the cooling air curtain and offers a less intrusive side closure of the refrigerated display cabinet, also in the area of the shelf structure.
  • the advantages of the design of the refrigerated display cabinet according to the invention come into play particularly strongly if the upper auxiliary module has a holding device for a side window.
  • Such an integration of the side window and the upper auxiliary module gives a closed overall impression for the first and saves production costs for the second.
  • the holding device for a side window consists of a guide which engages around the side window on one of its upper corners on both surfaces.
  • the guide can consist, for example, of a triangular gap which surrounds the front upper corner of the side window.
  • the side window rests with its upper edge in the region of the upper auxiliary module on the auxiliary module.
  • the side pane can now be attached to the upper auxiliary module.
  • the guide does not need to be filled in completely, since it not only encompasses the edge of the pane, but part of your surface.
  • the dimensions of the side window can thus vary within a relatively wide range without affecting their attachment or the clean side closure.
  • the main module of the side wall preferably has a rectangular shape. This is far easier to handle than more complicated surfaces during production, especially in the sandwich construction that is usually used to ensure satisfactory insulation of the goods area. Another advantage of reducing the production costs of such a symmetrical design is that identical main modules can be used for right and left side walls. This also applies to the usual different design of the outer and inner surface of a side wall.
  • auxiliary modules it is also possible to cover the entire ceiling part and / or the entire lower part laterally with auxiliary modules; the edges at which the main and auxiliary modules meet each other then run essentially horizontally.
  • another aspect of the invention offers significantly more advantages, namely the expansion of the main module essentially over the entire height of the furniture.
  • the area and volume of the auxiliary modules which are more expensive to manufacture due to their different design depending on the furniture variant, can thus be kept as small as possible.
  • the dividing lines between the main and auxiliary modules are then aligned approximately vertically.
  • connection between the main module and the auxiliary module is releasable in the refrigerated display case and in particular is realized by a screw, plug or clamping device. This enables particularly quick and easy assembly when assembling the modules to form a side wall.
  • a particularly suitable device for connecting the two components of a side wall is favorable.
  • the device for connecting the two components has bolts which are fastened to one of the two components, and guides and eccentrics which are arranged on the other of the two components, the bolts being located in the guides and held in place by the eccentric.
  • the bolts are preferably located on the front edge of the first component and guides and eccentrics on the rear edge of the second. More bolts can be provided as eccentrics in order to increase the lateral stability of the connection. In any case, a properly machined guide must be available for each bolt.
  • a cover is provided on the module which has an eccentric. After assembling the side wall, this covers the part of the fastening device that is still visible by assembling the main and auxiliary modules.
  • the cover preferably consists of an attachable plate. It can also be bent at a right angle and, for example, encompass the edge between the outside and top of the corresponding module.
  • the modules or cover and module with eccentric are preferably designed so that the outer surfaces of the auxiliary module and main module or of auxiliary module, main module and cover merge into one another.
  • the part of the module with eccentric clad by the cover is offset inwards in order to be able to accommodate the cover.
  • the stability of the connection between the main and auxiliary modules can be increased if a pair of adjoining end faces of two modules has a web on one end face and a groove on the other end face, in which this web engages.
  • the refrigerated display case shown in FIG. 1 has a shelf structure 1 as the upper goods space and below it a lower goods space 2. This is closed at the front by a front wall 3; you could also call it a chest or tub.
  • the lower goods area 2 projects forward over the front edges of the display shelves 4 of the shelf structure 1, as does the ceiling part 5, which in addition to an air outlet opening for the cooling air curtain generally also houses a lighting device.
  • the goods rooms 1, 2 are delimited on both transverse sides by a side wall 6 each.
  • the side walls 6 are constructed according to the invention in a modular manner, namely from one main module 7 each and from this special embodiment in each case two auxiliary modules 8, 9.
  • the main module 7 has the shape of a rectangle and by far takes up the largest proportion of a side wall 6. It is supplemented by a lower auxiliary module 8, which laterally covers the front area of the lower goods space 2 up to the front wall 3, and by an upper auxiliary module 9, which covers the section of the ceiling part 5 which is drawn forward.
  • FIG. 2 shows, with a view of the inside of a side wall, a first fastening method between the main module 7 and the auxiliary module 8.
  • the upper auxiliary module 9 can of course be fastened to the main module 7 in the same way, of course.
  • the bolts 10 of the first group are inserted into correspondingly machined guide holes in the auxiliary module 8.
  • the two fastening bolts 11 are fixed during assembly with the aid of two corresponding eccentric screws 12.
  • the two modules 7, 8 are equipped with a stable connection which can be detached and closed with little assembly effort.
  • the auxiliary module 8 can have any other shape and can thus be adapted to the most varied of furniture variants.
  • FIG 3 shows the inner structure of the side wall modules 7, 8, 9, which is practically identical in both auxiliary and main modules.
  • the modules have an outer wall 13 on the outside, which generally consists of painted sheet metal.
  • the inner surface 14 is usually made of impact-resistant plastic.
  • the intermediate space 15 between the inner and outer walls 14, 13 is filled with insulating material, for example expanded polyurethane. Since the right and left side wall of a piece of furniture sold are symmetrical, but are not constructed identically because of the different materials on the inside and outside surface, they cannot generally be produced in one operation. This also applies to the auxiliary modules 8 and 9 in the design according to the invention. However, if the main module 7 is rectangular, as in the exemplary embodiment in FIG. 1, identical main modules can be used for the right and left side walls. This significantly reduces the manufacturing effort and costs.
  • FIG. 4 shows a modified connection mechanism.
  • a device consisting of bolts 11 on the main module 7 and guides 16 and eccentric screws 12 on the auxiliary module 8 is used for locking, as in FIG.
  • the additional lateral stabilization is brought about here by webs 17a, 17b, 17c which engage in corresponding grooves 18a, 18b, 18c in the main module 7.
  • FIG. 5 shows the fastening device on an auxiliary module 8, which is similar to that of FIG. 2.
  • the eccentric screws 12 can, however, be covered with the aid of a cover 19. This also allows the eccentric screws 12 to be operated from the outside of the piece of furniture, which further reduces the assembly effort. There is no risk of injury to the finished furniture since the outside of the main module 8, cover 19 and main module, not shown, merge into one another.
  • auxiliary module 8 As shown in FIGS. 4 and 6, the insulation at the transition point between auxiliary module 8 and main module can be improved by milling grooves 21 into the end face 20 of one of the two modules (here of auxiliary module 8), which are used to hold sealing material (for example Sealing tape or sealing cord) are suitable.
  • sealing material for example Sealing tape or sealing cord
  • FIG. 8 shows a view of the side wall 6 of a slightly different embodiment of a piece of sales furniture according to the invention.
  • a particularly simple and inexpensive attachment of a side window 22 (generally made of glass or transparent plastic) is realized.
  • the side window 22 lies with its surface facing the interior of the furniture against a support surface 23 of the upper auxiliary module 9. Its front upper corner (shown hidden in FIG. 8) is seated in a guide 24. This is formed by an extension arm 25 which engages around the outside of the side window 22.
  • this holding device for the side window can best be seen in the enlarged sectional views in FIGS. 9 and 10.
