A refrigerated shelf of this kind is in the DE 20 2006 007 152 U1 shown. In this known refrigerated shelving two side stand modules are present, which are constructed C-shaped from two vertical uprights U-shaped cross-section and with a firmly welded upper and lower traverse. The lower truss is pushed into a trough-like floor module and can be screwed on during assembly. For this purpose, the bottom pan, which also contains a heat exchanger and a Ventillatorbaugruppe must have a correspondingly stable, suitable for the assembly of the stator module structure, which is associated with a respective effort.

The US 5 517 826 A shows a refrigerated shelf with an upper, heat-insulating shelf structure and a lower external frame structure, which has a base portion and a vertical portion. The shelf structure and the vertical portion have vertical struts between which an outer plate of a rear wall portion is mounted.

Another refrigerated shelf is in the US 2010/313588 A1 shown. In this cooling rack, a frame is also formed from a plurality of wall elements, wherein frame parts are also connected to a rear wall element. The JP H11 276315 A shows a refrigerated shelf with an upper and lower box-like shelf part.

In the WO 2011/074994 A1 as well as in the WO 2011/074993 A1 Refrigerated shelves are shown with C-shaped cross-section and with the bottom side, back wall side and roof side trim parts, between which an air curtain is formed. The cladding together with side walls form a furniture carcass, which stands up on the floor by means of feet.

In general, such refrigerated shelves have a C-shaped cross-section, wherein the requirements for a stable structure with the simplest possible assembly of the trim parts and cooling components while taking into account an efficiently usable cooling space are difficult to meet.

The lower horizontal profiles are provided with feet standing up on the floor and paneling parts with heat-insulating plate-shaped elements are mounted on the inside of the side frames to the refrigerator compartment. This design of the cooling rack results in a stable construction with well insulated on the back and top and bottom encapsulation, being mounted to increase the stability between the lower and upper horizontal profiles at a distance from the rear vertical profiles support profiles with the interposition of heat insulating elements. This basic structure with load-bearing C-frames, on which the trim parts are mounted and heat components of the rear panel assembly, roof group and floor assembly are supported, already offers significant advantages in terms of the structure and function of the cooling rack, compared to the hitherto existing state of the art.

The present invention has for its object to provide a cooling rack of the type mentioned, with which the installation options and method of installation can be improved.

This object is achieved with the features of claim 1. It is provided that between the C-shaped side frame at least one of these laterally spaced and opposite this differently shaped C-shaped intermediate frame with a horizontal bottom-side intermediate strut, another vertical intermediate strut and a roof-side intermediate strut is present. At the itself already a high carrying capacity having lateral C-shaped frame, which stand up with their lateral feet provided with floor struts on the ground, together with the C-shaped intermediate frame, which in turn are supported with the bottom-side intermediate struts feet on the ground, results in an increased stability of the provided with the trim parts cooling shelf. The opposite the lateral C-shaped frame differently shaped C-shaped intermediate frame advantageously result in customizable installation options with simple installation. This also contributes to efficient design options of the cooling function and use by the user. The side frames and the intermediate frames are preferably made of metal, in particular steel profiles. The side frames and the intermediate frames form separate units with respect to the trim parts, d. H. they are not formed by these, but carry them.

Favorable mounting options for attaching trim parts and / or components of the cooling device are obtained in that the at least one roof-side intermediate strut and / or the lateral roof struts hat / has profile profile.

For the assembly, further advantages result from the fact that the cavity of the roof-side intermediate strut downwards and the cavity of the lateral roof struts is open at the top.

Further advantages for the construction and assembly result from the fact that the at least one vertical intermediate strut and / or the lateral vertical struts have / has hat-shaped profile cross section.

Also, the features that the at least one bottom-side intermediate strut hat-shaped cross-section, contribute to advantageous installation and mounting options.

The structure is further facilitated by the fact that the lateral floor struts is designed as a closed hollow profile with a square or rectangular cross-section or has a C-shaped or hat-shaped cross-section.

For the assembly, further advantages result from the fact that the lateral vertical struts are braced against the rear end sides of the lateral roof struts and the lateral floor struts with or without intermediate piece and that the vertical intermediate struts against the rear end sides of the (associated) roof-side intermediate struts and the (assigned) bottom-side intermediate struts are clamped with or without intermediate piece.

In this case, a stable connection with simple handling is achieved in that for clamping the lateral vertical struts with the associated lateral roof struts and the associated lateral floor struts and / or for bracing the vertical intermediate struts with the associated roof side and bottom-side intermediate struts in the vertical struts facing rear mounting portions of the lateral roof struts and the lateral floor struts and the vertical intermediate struts facing rear mounting portions of the roof side and bottom intermediate struts transverse to the longitudinal axis extending fasteners are used with threaded holes in the through the associated vertical struts and the associated vertical intermediate struts guided clamping screws are screwed.

Furthermore, for the construction, the measures are advantageous in that the lateral vertical struts and the associated lateral floor struts are connected by means of a stiffening angle.

For the stability and construction of the cooling rack, the measures are also advantageous in that a respective vertical support strut is installed at a distance from the vertical strut between the lateral side strut and the roof strut of the two lateral frames in the rear area. Accordingly, also spaced from the vertical intermediate struts forward support struts between the associated floor struts and roof struts are installed, the front sides of all support struts are aligned parallel to the back plane with each other. In the built-in side frames support struts laterally projecting mounting flanges are omitted on the outside.

The structure and the function of the cooling rack are further promoted in that the covering parts comprise heat-insulating plate-shaped elements, which are mounted on the inside of the refrigerator side facing the frame and the intermediate frame.

Other advantages for the structure and function result from the fact that the support struts are provided with rows of holes in a predetermined grid spacing, which cantilevered forward to the refrigerator support arms are suspended and that the existing metal struts against the existing metal side roof struts and Floor struts and the bottom side and roof side intermediate struts are installed supporting over heat insulating spacers.

For the structure is further provided that front and rear feet are attached with height adjustment on the lateral floor struts and the bottom-side intermediate struts.

In the front region of the roof group 5, a roller blind for closing the refrigerator can be provided on the front to z. B. outside sales hours to store the cooling air in the refrigerator.

As Fig. 2 shows, the cooling rack 1 as a supporting framework, a frame with a plurality of side view C-shaped frame, namely two lateral frame 10 and preferably at a regular distance therebetween intermediate frame 10 ', wherein in Fig. 2 two intermediate frame 10 'are present. The distance between successive frames corresponds to z. B. the width of a conventional shelf module of 1.25 m width (one line), after which in the Fig. 1 and 2 Shelf arrangement shown exemplified three lines and z. B. has a width of 3.75 m. About the intermediate frame 10 'an advantageous stable continuous connection of the shelf modules is achieved. The frame 10 and intermediate frame 10 'are with respect to the trim parts, in particular the heat-insulating insulation, arranged on the outside of the cooling rack 1, so that cold spots are avoided to the outside and also favors the assembly steps in the construction of the cooling rack 1. On the underside, the frames 10 and the intermediate frames 10 'are provided with a bottom support 7 comprising front and rear feet 70, 71. Furthermore, in the embodiment shown, an adjustable securing support element 72 for additional stability is arranged on the side frame 10 at the bottom on the rear side.

Fig. 2 also shows in the rear wall group 2 arranged fan 61 and arranged in the roof group fan 61 '.

The lateral frames 10 each have a lateral vertical strut 40, a lateral floor strut 20 attached to the lower end thereof projecting in the direction of the depth, and a lateral roof strut 50 attached to its upper end and protruding forward in the direction of the depth. The intermediate frames 10 'each have a vertical intermediate strut 41, a forwardly projecting bottom-side intermediate strut 21 attached to the lower end region thereof and a roof-side intermediate strut 51 projecting at its upper end region and protruding forwardly. In order to connect the lateral vertical strut 40 to the lateral bottom strut 20, a stiffening angle 90 with a leg directed forwards and upwards along the bottom strut 20 and the vertical strut 40 may be attached (optionally in addition to further connecting elements). The bottom struts 20, roof struts 50, bottom-side intermediate struts 21 and roof-side intermediate struts 51 are preferably aligned horizontally or at right angles relative to the associated vertical struts 40 and vertical intermediate struts 41. To stiffen the frame 10 and intermediate frame 10 'are between the bottom strut 20 and the relevant roof strut 50 and between the bottom-side intermediate strut 21 and respective roof-side intermediate strut 51 in Fig. 1 shown supporting struts 80 at the same distance from the vertical struts 40 and vertical intermediate struts 41 mounted in the rear region of the cooling rack 1, wherein the front ends of the support struts 80 are supported on heat insulating bearing blocks 81 on the bottom strut 20 and bottom intermediate strut 21 and also between the upper End of the support strut 80 and the associated roof strut 50 and roof-side intermediate strut 51 corresponding heat-insulating elements are arranged to avoid cold bridges to the outer frame parts, since the support struts 80 and the horizontal and vertical frame legs in the form of lateral vertical struts 40, vertical intermediate struts 41st , lateral floor struts 20, bottom-side intermediate struts 21, lateral roof struts 50 and roof-side intermediate struts 51 to ensure the required Stability and good mounting options preferably made of metal, especially steel are formed. The in the intermediate frame 10 'built-in support struts 80 have, for example, on both sides parallel to the backplane beveled mounting flanges. However, in the support brackets 80 built into the side frames 10, preferably only one mounting flange oriented inwardly parallel to the backplane is present, while no outwardly facing mounting flange is present.

As Fig. 2 further shows, the side frame 10 and intermediate frame 10 'are constructed differently. The lateral vertical struts 40 are formed as profiles with hutförmigem cross-section, ie with a U-shaped in cross-section and right-angled bent outward free ends of the U-legs. With this structure, advantageous mounting options arise, wherein the U-web and the right angles bent outwards U-legs define mutually defined parallel spaced flange mounting surfaces into which mounting holes can be introduced at appropriate locations. The lateral roof struts 50 of the side frame 10 are formed according to the vertical struts 40 of a profile with hutförmigem cross-section. Both in the vertical struts 40 and the roof struts 50 of the profile cavity is open to the outside. This results in a stable mounting of the frame legs together and also advantages in the assembly of the plate-shaped trim parts and the side walls 3. The side floor struts, however, are preferably made of a closed rectangular or square hollow profile or C-shaped profile, which is a high stability in connection with the bottom support 7 and at the same time provide good mounting options for the vertical struts 40 and side walls 3.

In the intermediate frame 10 ', the vertical intermediate struts 41 and the roof-side intermediate struts 51 also consist of a profile with hutförmigem profile cross-section, wherein the profile dimensions in cross section advantageously correspond to the profile dimensions of the vertical struts 40 and roof struts 50. However, the roof-side intermediate struts 51 are swept with their opening side down to the refrigerator to get inside the refrigerator and on the outside of the roof group 5 better mounting options. For this purpose, the roof-side intermediate struts 51 are provided on their upper side with recesses 510, which extend in the example shown approximately from the front third to the vicinity of the rear end portion. In the recesses can on the top z. B. advantageous components of the cooling device 6 as a heat exchanger 62 are arranged defined. The bottom-side intermediate struts 21 are likewise formed from a profile with hat-shaped cross-section, wherein the opening of the profile cavity is directed upwards to the cooling space. The formed above lying angled lateral flanks result in advantageous mounting surfaces for the cladding elements and z. B. the bearing blocks 81. At the lateral edges of the U-legs of the central profile section, the front and rear feet 70, 71 are taken stable and adjustable in relevant recordings. The profile cross-section of the bottom-side intermediate struts 21 is wider than the profile cross-section of the vertical and roof-side intermediate struts 41 and 51, respectively, in order to obtain cheaper mounting options.

Fig. 3 shows an intermediate frame 10 'in a perspective view in the disassembled state. Here, the roof-side intermediate strut with its recess 510 can be clearly seen, wherein the recess 510 is followed by a rear upper mounting portion 511, at its front side, the vertical intermediate strut 41 with the facing web of their U-section directly or indirectly with the interposition of an intermediate piece in Appendix brought and clamped by means of a introduced from the back through a respective bore of the vertical intermediate strut 41 fastener 513 in the form of a fastening screw becomes. The fastening screw is screwed into a threaded mounting hole in a fixing piece 512, which is inserted at right angles to the longitudinal axis of the roof-side intermediate strut 51 inserted therein transverse slots.

Also, the connection of the vertical intermediate strut 41 with its lower portion on the bottom intermediate strut 21 takes place on the end side of the bottom-side intermediate strut 21. For this purpose, a contact piece is used at a lower rear attachment portion 210 of the bottom-side intermediate strut 21, to which the vertical intermediate strut 41 is attached as described in more detail below.

Fig. 3 also shows the mounting of the heat-insulating, made of stable plastic material bearing blocks 81 on the outwardly directed flange-like portions of the bottom intermediate strut 21 by means of fastening screws 810th Fig. 3 also shows the attachment of the front and rear feet 70, 71 on the bottom intermediate strut 21. For this purpose, a receptacle is attached to the U-legs of the U-section of the bottom intermediate strut 21, which is provided with an internal thread or connected to a threaded bolt 700, 710 of the front and rear stand 70 record vertically adjustable. The threaded bolt projects upwards over the top of the bottom intermediate strut 21 and has in its upper portion an approach for a tool such. B. a recording for an Allen key. With this design, the front and the rear foot 70, 71 can be easily adjusted from above, ie from the interior of the cooling rack, as the arrows in the direction of rotation and in the height direction illustrate. In particular, the rear foot 71, which is offset from the rear of the cooling rack 1 forward approximately up to the region of the support strut 80, and indeed slightly before the longitudinal axis, can be easily operated in this way for height adjustment. The bearing blocks 81 and possibly covering elements have corresponding access openings or can be brought out of the range of the tool approach in a simple manner. The front and the rear foot 70, 71 are attached to the two different legs of the U-section, which results in an increased stability.

In Fig. 5A Furthermore, the rear stand 71 is shown, which is fixed to a side leg of the U-section 214 of the bottom-side intermediate strut 21 stable in a cylindrical receptacle. The receptacle is itself provided with an internal thread or connected to an internal thread receiving nut, so that the rear base 71 is guided vertically adjustable with its threaded bolt 710 in the vertical direction. The threaded bolt 710 provided with the tool attachment, in the exemplary embodiment an Allen receptacle, projects beyond the upper side of the intermediate strut 21 on the bottom, wherein the outwardly bent flange portion 215 is pierced at the point of insertion of the threaded bolt 710. In order to increase the stability, in particular in the area of the rear stand 71 (and also in the area of the front stand 70), a screw can be transversely performed by the U-section of the bottom intermediate strut 21 with which the U-legs are stabilized in their orientation become. In the folded flange portions 215 are further fastening holes 216 z. B. for the bearing blocks 81 and implementation of the mounting screws 810 introduced. Fig. 5B shows the attachment of the bearing blocks 81 by means of fastening screws 810. Furthermore, again the described manner of mounting the vertical intermediate strut 41 on the bottom intermediate strut 21 and the attachment and height adjustment of the rear stand 71 can be seen, the rotation and height adjustment are symbolized by arrows.

The Fig. 5C shows the attachment of the vertical intermediate strut 41 with its U-section 410 on the bottom-side intermediate strut 21, wherein the side flange portions 411 of the vertical intermediate strut 41 protrude beyond the end face of the lateral fixing lugs 212 in the clamped state. Here, the fixing lugs 212, as in the embodiments according to Fig. 5A and 5B may be the case, formed as projecting portions of the U-legs of the bottom intermediate strut 21, in which case the investment piece 213 is received between the lateral fixing lugs 212 and only in its upper region with laterally over the fixing lugs 212 projecting portions in particular to the remote, after externally beveled flange portions 215 of the bottom-side intermediate strut 21 bears frontally and in the lower region z. B. is stably supported on the front side accordingly staggered U-web. Further shows Fig. 5C in turn attached to the bottom-side intermediate strut 21 rear pedestal 71 with the threaded bolt 710 and the attachment of the bearing blocks 81 by means of the mounting screws 810 in a perspective view of the opposite Fig. 5B other side.

Also from Fig. 5D the attachment of the vertical intermediate strut 41 on the bottom intermediate strut 21 in the manner described above can be seen. Furthermore, the rear foot 71 is shown with the threaded bolt 710. As a further component is a heat-insulating Bodenabdeckteil 22 z. B. from a plastic foam, which is placed on the facing folded flange portion 215 of the bottom-side intermediate strut 21 and with this z.
