     DETAILED DESCRIPTION 
     Reference is now made to  FIG. 1 , which depicts a schematic front view of a domestic cooling appliance  10 . Although exemplarily described by means of the domestic cooling appliance  10 , the present invention is not limited thereto. Rather, a shelf assembly according to the present invention may be mounted to any suitable rear wall structure in domestic homes or any other desired locations. The domestic cooling appliance  10  may particularly but not exclusively refer to a refrigerator or a freezer and may therefore be suitable to cool or freeze objects such as food to a certain temperature. The domestic cooling appliance  10  has the form of a cabinet that includes a corpus  12 , a bottom wall  14 , a top wall  16 , a rear wall  18  (also a rear wall structure  18 ) and a pair of side walls  20 . The corpus  12  is framed by the bottom wall  14 , the top wall  16 , the rear wall  18  and the pair of side walls  20 , thereby forming an access opening  22 . A user can access a cooling space  24  of the domestic cooling appliance  10  through the access opening  22 , which can be closed by a cabinet door  26  that is mounted to one of the pair of side walls  20 . 
     The cooling space  24  of the domestic cooling appliance  10  may comprise a plurality of mounting parts suitable for the user to apply objects that are supposed to be cooled or frozen. At least one of these mounting parts constitutes a shelf assembly  28  that comprises a shelf panel  30 . The shelf panel  30  may be manufactured from glass or plastics or any other suitable material. The material may be transparent or translucent. The shelf panel  30  may further include structures suited to obtain a desired light-deflecting effect. The shelf panel  30  may be from substantially rectangular shape and has a front edge facing the access opening  22 , a rear edge facing the rear wall  18  and a pair of lateral edges extending between the front and rear edges, each of them facing one of the side walls  20 . The shelf assembly  28  further comprises a pair of support brackets  32 , each of them being disposed adjacent one of the lateral edges of the shelf panel  30 . The support brackets  32  may be fully or partially formed from any suitable conductive material as e.g. metal. The support brackets  32  may have, but are not limited to, a cantilever design. In  FIG. 1 , only one of the pair of support brackets  32  is shown by a dashed line. Each of the support brackets  32  includes at least one mounting member (not shown), e.g. a reinforced hook or any other suitable structure for mounting the support brackets  32  to mounting structures (not shown) of the rear wall  18  of the domestic cooling appliance  10 . The domestic cooling appliance  10  of  FIG. 1  further comprises at least one additional shelf panel  34  suitable for the user to apply objects such as food. Although not shown, the shelf panel  34  may be a part of a shelf assembly that is identically formed to the shelf assembly  28 . 
       FIG. 2  depicts an exemplary shelf assembly  28  according to an embodiment of the present invention. The shelf assembly comprises a shelf panel  30  and a pair of support brackets  32  as described with reference to  FIG. 1 . Further, the shelf assembly comprises a coupling member  36  that is arranged to couple the shelf panel  30  to the pair of support brackets  32 . The coupling member  36  may be fully or partially manufactured from plastic or metal or from any other suitable material. In the embodiment shown, the coupling member  36  is designed as an elongated profile member and substantially extends alongside the rear edge of the shelf panel  30 . According to  FIG. 2 , the coupling member  36  has opposite longitudinal end portions that are each connected to one of the pair of support brackets  32  by a bolt connection  38 . 
     Although the shelf assembly  28  in  FIG. 2  comprises a single coupling member  36 , the present invention is not limited thereto. For example, the shelf assembly  28  may also comprise two or more coupling members  36 . Details of the one or more coupling members  36  according to the present invention will now be described with reference to  FIGS. 3-7 . The respective Figures show different variations of a coupling mechanism between the shelf panel  30  and the support brackets  32  as indicated in  FIG. 2  by means of differently shaped and arranged coupling members  36 . In the Figures, equal components or components of equal function are supplied with the same reference signs, but may be discriminated by different small letters appended to the respective reference signs. 
       FIG. 3  shows a perspective view of the rear side of a shelf assembly  28   a.  The rear edge of the shelf panel  30   a  is facing the rear wall  18  of the domestic cooling appliance  10  of  FIG. 1 . The same applies for  FIGS. 4 and 6 . 
     As shown in  FIG. 3 , the coupling member  36   a  is designed as an elongated profile member that is mounted to extend alongside one of the lateral edges of the shelf panel  30   a.  The coupling member  36   a  comprises a first pocket  40   a  configured to receive the shelf panel  30   a.  According to the embodiment, the first pocket  40   a  has a general U-shape in cross-section and comprises a pocket bottom and opposite side surfaces extending from the pocket bottom. The opposite side surfaces define a pocket interior therebetween. In the following, a coupling mechanism between the shelf panel  30   a  and the coupling member  36   a  is described. The shelf panel  30   a  extends into the first pocket  40   a  substantially as far as the pocket bottom. In an alternative embodiment, the shelf panel  30   a  may extend into the first pocket  40   a  substantially as far as the half of a length of the opposite side surfaces of the first pocket  40   a  or as far as two thirds of the length of said side surfaces. The shelf panel  30   a  may be clamped between the opposite side surfaces of the first pocket  40   a.  In such an embodiment, the respective side surfaces of the first pocket  40   a  apply an initial load that suffices to securely hold the shelf panel  30   a  therebetween in a stable manner. Additionally or alternatively, the shelf panel  30   a  may be fixated in the first pocket  40   a  by an adhesive, such as e.g. a resin. The adhesive may be applied between an upper surface of the shelf panel  30   a  and one of the side surfaces of the first pocket  40   a  facing the upper surface of the shelf panel  30   a.  From a predetermined amount of the adhesive, all or just a part of it may be applied in the described manner. Alternatively or additionally, the adhesive may be fully or partially applied between the pocket bottom of the first pocket  40   a  and the adjacent side edge of the shelf panel  30   a  and/or between a lower surface of the shelf panel  30   a  and the side surface of the first pocket  40   a  facing the lower surface of the shelf panel  30   a.    
     As it is further illustrated in  FIG. 3 , the coupling member  36   a  comprises a second pocket  42   a.  Although the present invention is not limited thereto, the second pocket  42   a  extends in an orthogonal plane with respect to the first pocket  40   a.  In an alternative embodiment, the first pocket  40   a  and the second pocket  42   a  may extend in mutually different, e.g. skew planes. The second pocket  42   a  is configured to receive one of the pair of support brackets  32   a.  As depicted in  FIG. 3 , the second pocket  42   a  has a general U-shape in cross-section and comprises a pocket bottom and opposite side surfaces extending from the pocket bottom. The opposite side surfaces define a pocket interior therebetween. In the following, a coupling mechanism between one of the pair of support brackets  32   a  and the coupling member  36   a  is described. Although not limiting, one of the pair of support brackets  32   a  extends into the second pocket  42   a  substantially as far as the pocket bottom. In an alternative embodiment, the one of the pair of support brackets  32   a  may extend into the second pocket  42   a  substantially as far as the half of a length of the opposite side surfaces of the second pocket  42   a  or as far as two thirds of the length of said side surfaces. The one of the pair of support brackets  32   a  may be clamped between the side surfaces of the second pocket  42   a.  In such an embodiment, the respective side surfaces of the second pocket  42   a  apply an initial load that suffices to securely hold the one of the pair of support brackets  32   a  therebetween in a stable manner. Additionally or alternatively, the one of the pair of support brackets  32   a  may be fixated in the first pocket by an adhesive, such as e.g. a resin or a solder. The resin may optionally be applied between one of the side surfaces of the second pocket  42   a  or the pocket bottom of the second pocket  42   a  and an adjacent surface or edge of the respective support bracket  32   a.  Alternatively, the resin may be applied between both the two side surfaces as well as the pocket bottom of the second pocket  42   a  and the adjacent surfaces and edge of the respective support bracket  32   a.    
     Turning now to  FIG. 4 , there is shown another example of a coupling member  36   b  of a shelf assembly  28   b.  Similarly to the embodiment in  FIG. 3 , the coupling member  36   b  is designed as an elongated profile member that is mounted to extend alongside one of the lateral edges of the shelf panel  30   b.  The coupling member  36   b  comprises a first pocket  40   b  that may be configured substantially similar to the first pocket  40   a  of the embodiment of  FIG. 3 . Further, a coupling mechanism between the first pocket  40   b  and the shelf panel  30   b  may be configured substantially similar to the coupling mechanism of the embodiment of  FIG. 3 . The coupling member  36   b  thus comprises the first pocket  40   b,  which is configured to receive the shelf panel  30   b.  The first pocket  40   b  has a general U-shape in cross-section and comprises a pocket bottom and opposite side surfaces extending from the pocket bottom. The opposite side surfaces define a pocket interior therebetween. The shelf panel  30   b  extends into the first pocket  40   b  substantially as far as the pocket bottom. In an alternative embodiment, the shelf panel  30   b  may extend into the first pocket  40   b  substantially as far as the half of a length of the opposite side surfaces of the first pocket  40   b  or as far as two thirds of the length of said side surfaces. The shelf panel  30   b  may be clamped between the opposite side surfaces of the first pocket  40   b.  In such an embodiment, the side surfaces of the first pocket  40   b  apply a sufficient force to securely hold the shelf panel  30   b  therebetween in a stable manner. The shelf panel  30   b  may be additionally fixated in the first pocket  40   b  by an adhesive, such as e.g. a resin. Adhesive may, e.g., be applied between an upper surface of the shelf panel  30   b  and one of the side surfaces of the first pocket  40   b  facing the upper surface of the shelf panel  30   b.  Alternatively or additionally, adhesive may be applied between the pocket bottom of the first pocket  40   b  and the adjacent side edge of the shelf panel  30   b  and/or between a lower surface of the shelf panel  30   b  and the side surface of the first pocket  40   b  facing the lower surface of the shelf panel  30   b.    
     In  FIG. 4 , the opposite side surfaces of the first pocket  40   b  which define the pocket interior therebetween are inner surfaces of opposite longer profile legs  41   a,    41   b  of the elongate profile forming the coupling member  36   b.  The pocket bottom is delineated by a shorter profile leg  41   c  of the elongate profile forming the coupling member  36   b.  The shorter profile leg  41   c  interconnects the longer profile legs  41   a,    41   b,  thereby defining the U-shaped first pocket  40   b.  The longer profile legs  41   a,    41   b  extend from the shorter profile leg  41   c  in a direction orthogonal or substantially orthogonal with respect to a plane defined by the pocket bottom. In the embodiment, the longer profile legs  41   a,    41   b  have a substantially equal length, while a length of the shorter profile leg  41   c  is smaller than the length of the longer profile legs  41   a,    41   b.  For example, the length of the shorter profile leg  41   c  may be one third or half the length of the longer profile legs  41   a,    41   b.  The longer profile legs  41   a,    41   b  may have a thickness of no more than 0.5 mm or no more than 1 mm or no more than 2 mm or no more than 3 mm. The same may apply to the length of shorter profile leg  41   c.    
     In embodiments, the longer profile legs  41   a,    41   b  may extend in a straight manner from the shorter profile leg  41   c  of the first pocket  40   b.  Alternatively, longer profile leg  41   a,  longer profile leg  41   b  or both longer profile legs  41   a,    41   b  may extend in a curved or at least arcuate manner from shorter profile leg  41   c  of the first pocket  40   b.  In the example of  FIG. 4 , longer profile leg  41   a  extends in an arcuate manner from shorter profile leg  41   c  while longer profile leg  41   b  extends in a straight manner from shorter profile leg  41   c.  A curvature of longer profile leg  41   a  is shaped such that a distance between the inner surfaces, when viewed from the plane defined by the pocket bottom of the first pocket  40   b,  decreases from the pocket bottom to substantially the middle of the first pocket  40   b  and increases again from the middle of the first pocket  40   b  to a top end of the first pocket  40   b.  Such arrangement of longer profile legs  41   a,    41   b  of the first pocket  40   b  defines a bottleneck therebetween, i.e. a narrow point within the first pocket  40   b  that supports the clamping of the shelf panel  30   b  between the opposite inner surfaces of longer profile legs  41   a,    41   b.  The curvature of longer profile leg  41   a  is not limited to the one described above. It is further conceivable that the curvature of longer profile leg  41   a  is shaped such that the described bottleneck is defined by the longer profile legs  41   a  and  41   b  at substantially one third or two thirds of a pocket depth extending from the pocket bottom to the top end of the first pocket  40   b.    
     In the embodiment of  FIG. 4 , the coupling member  36   b  is a bent component made from metal like aluminum or steel, for example unalloyed steel. The same material may be used for the pair of support brackets  32   b.  The coupling member  36   b  may be made from a single sheet component such as sheet metal. The pair of support brackets  32   b  may be made from a single metal plate. Compared to  FIG. 3 , the embodiment in  FIG. 4  applies a different coupling mechanism between the coupling member  36   b  and one of the pair of support brackets  32   b.  That is, instead of comprising a second pocket, one of the side surfaces of the first pocket  40   b  is configured to being fixedly attached to one of the pair of support brackets  32   b.  In particular, a surficial area of the first pocket  40   b  which is located at the opposite of a surficial area of the first pocket  40   b  that is engaged with the shelf panel  30   b  is formed to establish a connection to an upper edge of the one of the pair of support brackets  32   b.  The pertaining surficial area of the first pocket  40   b  may, although the present disclosure is not limited thereto, comprise a straight form in an area of contact with the upper edge of the one of the pair of support brackets  32   b.  In  FIG. 4 , the coupling member  36   b  as well as the support brackets  32   b  may be formed from metal, but are not limited thereto. The fixed connection between the one of the side surfaces of the first pocket  40   b  and the one of the pair of support brackets  32   b  is established by a weld or solder connection. When a weld connection is established, the connection may be established by spot-welding. 
     The coupling mechanism between the coupling member  36   b  and one of the pair of support brackets  32   b  when a weld connection is established between the one of the side surfaces of the first pocket  40   b  and the one of the pair of support brackets  32   b  will be described in more detail below. 
     The side surfaces of the first pocket  40   b  are defined by outer surfaces of the longer profile legs  41   a,    41   b  of pocket  40   b.  As shown in  FIG. 4 , the outer surface of longer profile leg  41   a  may be a curved surface. A curvature of the curved surface may be formed substantially similar to the curvature of longer profile leg  41   a.  For welding, the one of the pair of support brackets  32   b  as well as the coupling member  32   b  are held and aligned with respect to each other utilizing clips or other suited clamping means. Then, the one of the pair of support brackets  32   b  is welded to the curved outer surface of longer profile leg  41   a  substantially adjacent to the pocket bottom (i.e. in the area close to shorter profile leg  41   c ) of the first pocket  40   b.  The weld connection may be established by laser welding, but the invention is not limited thereto. The application of resistance welding or other suited welding technique is similarly conceivable. 
     In the embodiment, the weld between the first pocket  40   b  and the one of the pair of support brackets  32   b  is not a continuous weld (although such continuous weld is similarly conceivable). Rather, said weld may comprise a plurality of weld sections arranged alongside an extending direction of coupling member  36   b.  A distance between the respective weld sections may be between 2 cm and 15 cm and for example between 5 cm and 10 cm. A length of the respective weld sections may be between 2 mm and 15 mm and for example between 5 mm and 10 mm. Since the application of spot-welding is also conceivable to establish the weld between coupling member  36   b  and the one of the pair of support brackets  32   b,  a plurality of welding spots may be applied alongside the extending direction of coupling member  36   b  in alternative to the plurality of weld sections. A distance between the welding spots may be substantially similar to the distance between the weld sections described above. 
     After the weld connection between the coupling member  36   b  and one of the pair of support brackets  32   b  is established, the coupling member  36   b  as well as the one of the pair of support brackets  32   b  are coated in a single coating process. For the coating process, lacquer coating or powder coating (the present invention is not limited thereto) is applied to protect materials of the one of the pair of support brackets  32   b  and the coupling member  36   b  from corrosion and/or oxidation. 
     A front trim (not shown in  FIG. 4 ) made from plastic or metal may be applied to cover and protect the front edge of the shelf panel  30   b.  As an optional component, an illumination module (not shown in  FIG. 4 ) may further be applied to the front edge of the shelf panel  30   b.  The illumination module may comprise a plurality of light emitting diodes or other suited illumination means. If applied, the illumination module is received within the front trim of the shelf panel  30   b.    
     The illumination module may be supplied with electrical energy from a busbar provided behind the rear wall  18  and within corpus  12  of the domestic cooling appliance  10  (see  FIG. 1 ). When the shelf assembly  28   b  is mounted to the rear wall  18  of the domestic cooling appliance  10 , current flows from the busbar into the one of the pair of support brackets  32   b.  In a region adjacent the front edge of shelf panel  30   b  (thus equally in a region of a front edge of the one of the pair of support brackets  32   b  that faces the access opening  22  of the domestic cooling appliance  10 ), the coating of the one of the pair of support brackets  32   b  is removed, for example by way of die cutting or any other suited technique so that the material of the one of the pair of support brackets  32   b  is exposed to the outside in a relatively small region of exposure. This region of exposure may be circular in shape and may comprise a radius of around 1 mm or 2 mm or 4 mm or 8 mm. Alternatively, the region of exposure may be rectangular in shape an may comprise an edge length of around 1 mm or 2 mm or 4 mm or 8 mm. Other shapes and measures for the region of exposure are similarly conceivable. An electrical conductor may be coupled between the region of exposure and the illumination module. That is, the electrical conductor directly contacts the material of the one of the pair of support brackets  32   b  in the region of exposure and directly contacts a power input of the illumination module. At least the coupling between the electrical conductor and the region of exposure may be carried out in a gastight manner. Accordingly, current flows, after entering the one of the pair of support brackets  32   b  in a region near the rear wall of the domestic cooling appliance  10 , through the one of the pair of support brackets  32   b  and via the electrical conductor into the illumination module to provide the same with electrical energy. A return path for current flow from the illumination module to the busbar of the domestic cooling appliance  10  is configured in a similar manner via a second electrical conductor and the other one of the pair of support brackets  32   b.    
     A manufacturing process of a shelf assembly  28   b  that comprises the illumination module is basically the same as a manufacturing process of a shelf assembly  28   b  not comprising the illumination module. That is, the above described coupling by welding between the coupling member  36   b  and the one of the pair of support brackets  32   b  is identically carried out in either case. For a shelf assembly  28   b  that comprises the illumination module, creation of the region of exposure and application of the electrical conductor is additionally carried out. With that, it is possible to manufacture respective pairs of coupling members  36   b  and support brackets  32   b  for shelf assemblies with and without the illumination module within the same production line. 
     Turning now to  FIG. 5 , there is shown another example of a coupling member  36   c  of a shelf assembly  28   c.  In  FIG. 5 , there is provided a side view of the shelf assembly  28  of  FIG. 2 . In this embodiment, the coupling member  36   c  is designed as an elongated profile member that substantially extends alongside the rear edge of the shelf panel  30   c.  In this way, the lateral edges of the shelf panel may not be utilized to establish a coupling between the shelf panel  30   c  and the support brackets  32   c.  The coupling member  36   c  comprises a first pocket  40   c  that may be configured substantially similar to the first pockets  40   a  and  40   b  of the embodiments of  FIGS. 3 and 4 , respectively. Further, a coupling mechanism between the first pocket  40   c  and the shelf panel  30   c  may be configured substantially similar to the coupling mechanisms between the first pockets  40   a,    40   b  and the coupling members  36   a,    36   b  of the embodiments of  FIGS. 3 and 4 . The coupling member  36   c  has opposite longitudinal end portions that are each configured to receive at least one bolt element. The longitudinal end portions of the coupling member  36   c  may form end portions of a ridge extending alongside the rear edge of the shelf panel  30   c  and extending in an orthogonal plane with respect to a plane that comprises one of the opposite side surfaces of the first pocket  40   c.  Further, each of the pair of support brackets  32   c  is, in an area adjacent to the coupling member  36   c  (i.e. in the vicinity of the rear edge of the shelf panel  30   c ), configured to receive the at least one bolt element. As such, the longitudinal end portions of the coupling member  36   c  are connected to the support brackets  32   c  by a bolt connection  38 . The bolt element may be a screw, a pin or any other suitable element. 
     Additionally, the shelf assembly  28   c  may comprise second and third coupling members (for better discrimination designated  44  in  FIG. 5 ) that are mounted to corner regions of the shelf panel  30   c.  The respective corner regions in  FIG. 5  are each constituted by the front edge and one of the lateral edges of the shelf panel  30   c,  but are not limited thereto. The second and third coupling members  44  comprise a first pocket (not shown) that is configured substantially similar to the first pocket  40   c  of the coupling member  36   c.  Further, a coupling mechanism between the first pockets of the coupling members  44  and the shelf panel  30   c  may be configured substantially similar to the coupling mechanism between the first pocket  40   c  and the shelf panel  30   c.  However, the first pockets of the second and third coupling members  44  are configured to receive a portion of the front edge as well as a portion of the lateral edge that constitute the respective corner region of the shelf panel  30   c.  The coupling members  44  extend just to a minor part along the front edge and the respective lateral edge of the shelf panel  30   c.  To the most part, e.g. at least 95% or at least 90% or at least 85% or at least 80% of the lateral edges of the shelf panel  30   c  remain uncovered. This is particularly important since such a design allows a side-by-side positioning of two or more shelf assemblies  28   c  in the cooling space  24  of the domestic cooling appliance  10 . In such way, it is possible to obtain a space-saving design and to allow the user of the domestic cooling appliance  10  to conveniently slide objects between the two or more shelf assemblies  28   c.  The shelf assembly  28   c  may further comprise an elongate coverage profile that substantially extends alongside the front edge of the shelf panel  30   c  and covers the same. In some embodiments, the elongate coverage profile may be configured to house a light source, such as an LED-module, but is not limited thereto. The elongate coverage profile has opposite longitudinal end portions that are each configured to receive at least one bolt element. Further, each of the pair of support brackets  32   c  is, in an area adjacent to the respective coupling members  44  (i.e. in the vicinity of the front edge of the shelf panel  30   c ), configured to receive the at least one bolt element. As such, the coupling members  44  are connected to the elongate coverage profile by a bolt connection that additionally attaches the respective support brackets  32   c  to the elongate coverage profile. The bolt element may be a screw, a pin or any other suitable element. 
     As depicted in  FIG. 5 , the shelf panel  30   c  has direct contact with the support brackets  32   c  at least in the vicinity of the front and rear edges of the shelf panel  30   c.  On the other hand, the shelf assembly  28   c  comprises a gap between the support brackets  32   c  and the shelf panel  30   c  in a predominant area in a longitudinal direction of the lateral edges of the shelf panel  30   c.  Alternatively, the shelf panel  30   c  may have direct contact with the support brackets  32   c  substantially alongside the lateral edges of the shelf panel  30   c.    
     Turning now to  FIGS. 6 and 7 , there is shown another example of a coupling member  36   d  of a shelf assembly  28   d.  In the embodiment shown, the shelf assembly  28   d  comprises, but is not limited to, two coupling members  36   d.  The coupling members  36   d  each comprise a first pocket  40   d  and a second pocket  42   d  that are substantially configured similar to the first pocket  40   a  and the second pocket  42   a  of the embodiment of  FIG. 3 . Further, a coupling mechanism between the first pocket  40   d  and the shelf panel  30   d  as well as a coupling mechanism between the second pocket  42   d  and the support brackets  32   d  may be configured substantially similar to the respective coupling mechanisms of the embodiment of  FIG. 3 . Although not limiting, the second pocket  42   d  in  FIG. 7  extends in an orthogonal plane with respect to the first pocket  40   d.  In an alternative embodiment, the first pocket  40   d  and the second pocket  42   d  may extend in mutually skew planes. The coupling members  36   d  comprise a substantially rectangular upper surface that is located opposite to a side surface of the first pocket  40   d  that faces an upper surface of the shelf panel  30   d.  The coupling members  36   d  are disposed in corner regions of the shelf panel  28   d,  each receiving a portion of the rear edge and a portion of one of the lateral edges of the shelf panel  30   d.  As will be readily understood, the present invention is not limited thereto. The coupling members  36   d  may alternatively receive portions of the front edge and portions of the lateral edges of the shelf panel  30   d.  Similarly to the embodiment in  FIG. 5 , the coupling members  36   d  extend just to a minor part along the rear edge and the respective corner-forming lateral edge of the shelf panel  30   d.  To the most part, e.g. at least 95% or at least 90% or at least 85% or at least 80% of the lateral edges and the rear edge of the shelf panel  30   d  remain uncovered. This is particularly important since such a design allows a side-by-side positioning of two or more shelf assemblies  28   d  in the cooling space  24  of the domestic cooling appliance  10 . In such way, it is possible to obtain a space-saving design and to allow the user of the domestic cooling appliance  10  to conveniently slide objects between the two or more shelf assemblies  28   d.  Further, the shelf panel  30   d  is in direct contact with the support brackets  32   d  at least in the vicinity of the front and rear edges of the shelf panel  30   d.  On the other hand, the shelf assembly  28   d  comprises a gap between the support brackets  32   d  and the shelf panel  30   d  in a predominant area in a longitudinal direction of the lateral edges of the shelf panel  30   d.  Alternatively, the shelf panel  30   c  may have direct contact with the support brackets  32   c  substantially alongside the lateral edges of the shelf panel  30   c.    
     The embodiments disclosed herein describe variations of different coupling members and mechanisms between shelf panels and support brackets of shelf assemblies mounted into e.g. a domestic cooling appliance. The embodiments serve to optimize available space on the shelf panel and to enable a side-by-side positioning of two or more shelf assemblies under provision of a smooth transition between the respective shelf panels of the shelf assemblies. Further, all of the disclosed variations provide stable designs of shelf assemblies for the user to conveniently place, slide and take out objects such as food from the domestic cooling appliance.
