Title: Shelf assembly with specific carrier frame, and household cooling appliance with a shelf assembly

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     An aspect of the invention relates to a shelf assembly for a household cooling appliance. A further aspect of the invention relates to a household cooling appliance. 
     U.S. Pat. No. 9,103,582 B2 discloses a shelf assembly. That assembly comprises two glass plates, which are each surrounded by a frame. The two plates are shiftable relative to each other in depth direction of the assembly. Moreover, the assembly comprises a frame, by which these two plates are held. However, the frame only extends over the length of the rear plate with its side bars. The front plate is protruding forwards beyond the side bars in a use position. In this respect, the front plate freely cantilevers at the front. Thereby, this front plate is severely loaded in the use position. Large leverage forces act on the mechanical connection of this front plate to the frame. Moreover, it is provided in this known configuration of the assembly that holding brackets are a constituent of this carrying frame. However, these holding brackets are arranged virtually completely exposed. Thereby, functional impairments can result. Moreover, the attachment to and mounting on the remaining components of the carrying frame are restricted. The entire mechanical stability of the carrying frame is thereby reduced. 
     A shelf assembly is also known from U.S. Pat. No. 9,127,877 B2. There too, two separate shelves are provided. One of these two shelves is movably arranged on a carrying frame of this assembly. The front, movable shelf comprises laterally protruding pins. These pins serve for coupling to a guiding formed at the carrying frame. Both in the rear area of this front shelf and in the front area, correspondingly protruding pins are respectively formed. By such a configuration, jamming or strutting can result upon shifting this front plate. In particular if the plate does not perform a completely rectilinear movement in depth direction, but performs an S-like movement in this respect. Moreover, it is prevented by this configuration that the front plate is separated from the carrying frame at the front end in its use position. In this configuration too, it is provided that holding brackets of the carrying frame are arranged relatively exposed. Therefore, the disadvantages already mentioned to the above mentioned prior art apply here too in this respect. 
     Furthermore, from U.S. Pat. No. 8,840,205 B2 a shelf assembly is known. The construction is corresponding as in U.S. Pat. No. 9,127,877 B2 with respect to the essential aspects and the disadvantages already mentioned above.

     The shelf assembly  8  can be used as a compartment divider or compartment shelf. In an embodiment, the shelf assembly  8  also serves for depositing storage goods. Such storage goods are food like beverages or meal. 
     In  FIG. 2 , an embodiment of a shelf assembly  8  is shown in a perspective representation. The shelf assembly  8  comprises a first shelf  9 . The first shelf  9  comprises a base plate  10 . The base plate  10  can for example be of glass. However, it can for example also be of plastic. The base plate  10  is quadrangular in the embodiment. In particular, it is rectangular. In the embodiment, the first shelf  9  comprises a rear edge profile  11 . The designation with respect to the rear edge profile  11  relates to the position at the first shelf  9  to other components of the first shelf  9  viewed in depth direction. This rear edge profile  11  is a rectilinear ledge. It is in particular C-shaped or U-shaped in cross-section. In an embodiment, the edge profile  11  is formed without interruption. In an embodiment, the rear edge profile  11  extends across the entire width of the base plate  10 . This width is measured in width direction. The rear edge profile  11  is a component separate from the base plate  10  in an embodiment. 
     In an embodiment, the first shelf  9  comprises a front edge profile  12 . The front edge profile  12  is formed as a rectilinear ledge. It can be U-shaped or C-shaped in cross-section. In an embodiment, the front edge profile  12  is formed as a respectively separate component from the base plate  10  like the rear edge profile  11 . In an embodiment, the rear edge profile  10  can be fitted to the base plate  10 . In an embodiment, the front edge profile  12  can be fitted to the base plate  10 . In an embodiment, the rear edge profile  11  can be integrally formed of plastic. However, it can for example also be formed of metal. The front edge profile  12  can be integrally formed of plastic in an embodiment. However, it can also be formed of metal. 
     In an embodiment, this shelf assembly  8  comprises a second shelf  13 . The second shelf  13  is formed separate from the first shelf  9  in an embodiment. In an embodiment, the second shelf  13  comprises a base plate  14 . The base plate  14  is for example formed of glass. However, it can also be formed of plastic. Similarly as the base plate  10 , the base plate  14  can also be formed transparent at least in certain areas in an embodiment. 
     In an embodiment, the second shelf  13  can comprise a front edge profile  15 . In an embodiment, the front edge profile  15  is separate from the base plate  14 . In an embodiment, the front edge profile  15  extends across the entire width of the base plate  14 . The front edge profile  15  can be C-shaped or U-shaped in cross-section. In an embodiment, the front edge profile  15  is arranged at a front edge of the base plate  14 . It can be fitted thereto. 
     In an embodiment, the shelf assembly  8  comprises a carrier frame  16 . The carrier frame  16  is separate from the first shelf  9  and separate from the second shelf  13 . In an embodiment, the carrier frame  16  is U-shaped formed. In an embodiment, it comprises a first side bar  17 . Moreover, it comprises a second side bar  18 . The two side bars  17  and  18  extend in depth direction. The two side bars  17  and  18  are arranged parallel and spaced from each other. The two side bars  17  and  18  extend in depth direction. They are straight and bar-like. 
     Moreover, the carrier frame  16  comprises a connecting bar  19 . It connects the two side bars  17  and  18 . 
     In an embodiment, the second shelf  13  is the rear shelf in depth direction. This second shelf  13  is fixedly attached to the carrier frame  16  in an embodiment. In an embodiment, it can for example be adhered to the carrier frame  16 . In the shown embodiment, only a front edge  20  of the base plate  14  is provided with such a front edge profile  15 . Side edges  21  and  22  of the base plate  14  are not provided with further such separate edge profiles in the shown embodiment. Moreover, a rear edge  23  of the base plate  14  is not provided with such an edge profile in the shown embodiment. 
     In an embodiment, it is provided that the base plate  14  and thus the second shelf  13  have a width, which exactly corresponds to the distance between the two side bars  17  and  18 . Thereby, a lateral protrusion of the second shelf  13  viewed in width direction beyond these side bars  17  and  18  is avoided. In particular, the side edges  21  and  22  are arranged aligned to the outer sides of the side bars  17  and  18 . 
     In  FIG. 2 , a use position of the shelves  9  and  13  is shown. This means that the two shelves  9  and  13  are arranged one behind the other and in series to each other in depth direction. Thereby, a maximum entire shelf area of the shelf assembly  8  is formed. In an embodiment, the first shelf  9  is arranged movable to the second shelf  13 . In the state, in which it is arranged at the carrier frame  16 , it can be shifted relative to the second shelf  13  at the carrier frame  16 . In an embodiment, thereto, it can be shifted rearwards and below the second shelf  13  starting from the use position shown in  FIG. 2 . This is shown in  FIG. 3 . Thus, a non-use position of the first shelf  9  is shown there. It can be provided that the first shelf  9  can be positioned completely below the second shelf  13  viewed in depth direction. Thereby, a free space is formed between the side bars  17  and  18  in the non-use position of the shelf  9  shown in  FIG. 3 . Thereby, storage goods can be positioned in the receiving space  5  below the shelf assembly  8 , but which nevertheless extend into this free space  24 , as it is shown in  FIG. 3 , in vertical direction. Thereby, storage goods can also be positioned such that they can virtually extend upwards through the shelf assembly  8 . 
     In the embodiment according to  FIG. 2  and  FIG. 3 , it is provided that side edges  25  and  26  of the base plate  10  of the first shelf  9  are formed without a frame fixedly arranged thereon. Thus, edge profiles are in particular not arranged at these side edges  25  and  26 . In the shown embodiment, thus, only the front edge  27  is provided with the front edge profile  12  and a rear edge  28  in the rear edge profile  11 . 
     Moreover, it is apparent that the first shelf  9  is narrower in width direction than the second shelf  13  in an embodiment. In an embodiment, the first shelf  9  is arranged flush with a top face  30  of the second shelf  13  with a top face  29  when the use position of the shelves  9  and  13  shown in  FIG. 2  is set. 
     In  FIG. 3 , an embodiment is shown, in which a guide assembly or guide  31 , referred to herein as a guiding  31 , is also illustrated. In an embodiment, the guiding  31  is arranged at the first side bar  17  as well as at the second side bar  18 . Thereto, the guiding  31  comprises a first guiding part  31   a  ( FIG. 4 ). It is arranged at the first side bar  17 . A second guiding part of the guiding  31  is arranged at the second side bar  18 . The movably supported first shelf  9  can be guided in defined manner by the guiding  31 . In this context, it can be shifted in depth direction. 
     In  FIG. 4 , the first side bar  17  of the carrier frame  16  is shown in an exploded representation. The first side bar  17  comprises a housing  32 . In the shown embodiment, the housing  32  comprises a first housing part  33 . Moreover, it comprises a second housing part  34  separate from the first housing part  33 . The two housing parts  33  and  34  are elongated components. In an embodiment, they are each integrally formed. In this respect, they can for example be formed of plastic. The first guiding part  31   a  is arranged on an outer side  34   a  of the second housing part  34 . The two housing parts  33  and  34  are connected by a connection  35  ( FIG. 3 ). In particular, this connection  35  is a mechanical connection. It can for example be a snap-fit connection. 
     In  FIG. 3 , these two housing parts  33  and  34  are shown in the mounted final position. Thereby, they form the housing  32 . In this mounted final position, the housing  32  is such that it is closed at a front end  36  in the direction of its length axis B ( FIG. 3 ). In circumferential direction around the length axis B, the housing  32  is also completely closed. The housing  32  is open at a rear end  37 . In this respect, it comprises an opening  38 . In the assembled state of the two housing parts  33  and  34 , a hollow space  39  is formed in the interior of the housing  32 . This hollow space  39  is provided for receiving a separate holding bracket  40  as it is shown in  FIG. 4 . In an embodiment, the holding bracket  40  is integrally formed. For example, it can be formed of metal. The holding bracket  40  is sword-like formed in an embodiment. In this respect, it comprises an elongated, strip-shaped bracket part  41 . This bracket part  41  is introduced, in particular completely introduced, into the hollow space  31  in the mounted final state. In an embodiment, the holding bracket  40  comprises an end piece  42 . This end piece  42  is a rear end  40   a  of the holding bracket  40 . This end piece  42  is thickened with respect to the bracket part  41 . In an embodiment, the end piece  42  comprises holding hooks  43  and  44 . The shelf assembly  8  can be detachably attached to a household appliance component of the household cooling appliance  1  by these holding hooks  43  and  44 . In particular, it can be hooked into this household appliance component by these holding hooks  43  and  44 . For example, the household appliance component can be a rear wall. It can be the rear wall of the inner liner  4 . However, it can also be a rear wall separate from it. 
     As it is apparent in  FIG. 2  and  FIG. 3 , this rear-side end piece  42  of the holding bracket  40  extends rearwards out of the housing  32 . In this respect, the corresponding holding bracket  40  is shown in  FIG. 2  and  FIG. 3 , which is arranged in the second side bar  18 . The second side bar  18  is constructed corresponding to the first side bar  17  with respect to the housing  32  and thus the housing parts  33  and  34 . 
     By the configuration of the housing parts  33  and  34 , a tunnel-like or channel-like or scabbard-like housing  32  is also formed. By such a configuration, it is allowed that such an elongated, sword-like holding bracket  40  is introduced as extensively as possible. Thus, the holding bracket  40  is arranged at the carrier frame  16  circumferentially protected on the one hand. On the other hand, it can thereby also be arranged in mechanically improved manner. Thus, a more stable attachment of this separate holding bracket  40  to further components of the carrier frame  16  is in particular allowed. In an embodiment, it can be provided that the holding bracket  40  is positionally fixed to the housing parts  33  and/or  34 . Thereto, a detent can be provided. In this context, the holding bracket  40  can then be arranged in the housing  32  in positionally fixed manner at least in depth direction. Couplers  45  and/or  46  can be provided as the detent. They are formed at the holding bracket  40 , in particular the bracket part  41 , in the embodiment. Counter couplers, which then engage with these couplers  45  and  46 , can be formed at the housing part  33  and/or at the housing part  34 . 
     In  FIG. 4 , it is also shown in an embodiment that the connection  35  for example comprises latches  47  in an embodiment. They are only symbolically illustrated in  FIG. 4 . Both the number and the position can be manifold in this respect. These latches  47  can snap-fit to further latches formed at the second housing part  34 . Thereby, a snap-fit connection is formed. The latches  47  can be first latches in this context. Further latches can be formed at the second housing part  34  as second latches. 
     A mount for the holding bracket  40  is formed by the couplers  45  and  46  and the counter coupling elements  48 . In this embodiment, counter couplers  48  can for example be provided at the first housing part  33 . Here too, both the number and the position are definitely not to be understood in restricting or conclusive manner. 
     In an embodiment, the housing  32  comprises a top face  49 . This top face  49  comprises a first top face section  50  in an embodiment. Moreover, it comprises a second top face section  51 . The two top face sections  50  and  51  are extensive strips. They are oriented in series to each other in depth direction. The top face sections  50  and  51  are rectilinearly formed. The top face section  50  is formed consistently at a first level. The second top face section  51  is formed at a different level compared thereto. However, in an embodiment, the second top face section  51  is formed at a lower level than the first top face section  50 . A step  52  is formed at a transition between the top face sections  50  and  51  adjoining to each other. It forms the offset at the junction between the two top face sections  50  and  51 . 
     In an embodiment, the second shelf  13  is laid, in particular adhered, on the second top face section  51  from above. 
     Since the second side bar  18  is formed corresponding to the explanations to the first side bar  17  with respect to its configuration, the second shelf  13  is also laid, in particular adhered, on the corresponding top face section of the housing of the side bar  18 . 
     In  FIG. 4 , an embodiment of the first guiding part  31   a  at the first side bar  17  is also shown. This guiding part  31   a  comprises a strip-shaped guiding lay-on  53 . This guiding part  31   a , as it is provided at the first side bar  17 , is arranged exclusively at the second housing part  34  in the embodiment. It is in particular formed integrally with the second housing part  34 . 
     In the mounted final state of the two housing parts  33  and  34 , this strip-shaped guiding lay-on  53  is formed farther in the direction to the second side bar  18  viewed in width direction than the first housing part  33  extends in this respect. Thus, this strip-shaped guiding lay-on  53  extends farther in the direction to the second side bar  18  as also the top face  49  in width direction. Thereby, it is allowed that the shelf  9  only has to extend between the side bars  17  and  18  and can still be securely held and guided by laying on this strip-shaped guiding lay-on  53 . By this width extension of the strip-shaped guiding lay-on  53 , a guiding link open towards the top is thus virtually formed. Thus, there is no corresponding counterpart in the guiding  31 , which would cover such a guiding link towards the top. Thus, the first shelf  9  is virtually exposed towards the top upon guiding on this strip-shaped guiding lay-on  53  viewed in the area without guiding pins  57   a ,  57   b . It is not bounded or covered by a corresponding upper guiding lay-on opposing the strip-shaped guiding lay-on  53 . 
     As is apparent in  FIG. 4 , this strip-shaped guiding lay-on  53  comprises a ramp  54  in addition to the strip-shaped base lay-on  53   a  in an embodiment. The first shelf  9  is continuously moved into a higher position by this ramp  54  upon shifting from its non-use position shown in  FIG. 3  shortly before reaching the use position according to  FIG. 2 . Viewed in depth direction towards the front, this strip-shaped guiding lay-on  53  comprises a then again horizontal section  55 . It adjoins to the ramp  54  on the front side. In the final position shown in  FIG. 2  of the first shelf  9  in its use position, the first shelf  9  rests on this section  55  in particular with its front edge profile  12 . 
     Moreover, the guiding  31  comprises a further ramp  56  at its guiding part  31   a . This ramp  56  is narrower than the front ramp  54  viewed in width direction. The second ramp  56  is also narrower than this strip-shaped base lay-on  53   a . A guiding pin  57   a  ( FIG. 5  and  FIG. 6 ) is guided on this further ramp  56 . This guiding pin  57   a , as it is shown in  FIG. 5 , is formed at the rear edge profile  11 . It is laterally protruding beyond the base plate  10  in width direction. 
     In an embodiment, it is provided that only these two guiding pins  57   a  and  57   b  are provided. They are in particular formed integrally with the rear edge profile  11 . 
     In an embodiment, the first shelf  9  does not comprise further laterally protruding guiding pins any more except for these two rear guiding pins  57   a  and  57   b . Thus, it is provided in an embodiment that such guiding pins are not present in a front length half of the first shelf  9 . The length of this first shelf  9  is measured in depth direction of the shelf assembly  8  in this context. Thus, this front edge profile  12  does not comprise such laterally protruding guiding pins in an embodiment. The base plate  10  also does not comprise such guiding pins. Thus, it is provided that the first shelf  9  is only coupled to two such guiding pins  57   a  and  57   b  of the guiding  31  in particular formed in a rear length half of the first shelf  9  and laterally protruding in an embodiment. Upon forward shifting the first shelf  9  starting from the non-use position in  FIG. 3 , these guiding pins  57   a  and  57   b  are guided in this guiding part  31   a  and there then brought into a final position. In this final position, the guiding pin  57   a  is introduced in a receiving core  58  shown in  FIG. 4 . The guiding pin  57   a  is then also held in this receiving core  58 , which is a constituent of the first guiding part  31   a . The receiving core  58  is arranged at a level, which corresponds to the level of the section  55 . Thereby, the first shelf  9  is completely horizontally oriented in its use position according to  FIG. 2 . 
     The receiving core  58  is formed, in particular integrally formed, in the second housing part  34  in the shown embodiment. The receiving core  58  can also be referred to as receiving box or receiving recess. 
     In this respect too, the second side bar  18  is correspondingly formed. Thereby, the further guiding pin  57   b  can be correspondingly guided and positioned. The corresponding further ramp  56  is also formed there. 
     As is apparent in representations in  FIG. 3  and  FIG. 4 , this strip-shaped guiding lay-on  53  is formed in front of the second shelf  13  viewed in depth direction. In an embodiment, this strip-shaped guiding lay-on extends over at least 90 percent in the direction of the measured length of the first shelf  9  in the use position. Thus, the shelf  9  is also completely laterally bordered by the housing  32  over its entire length in its use position according to  FIG. 2 . 
     Thus, a front area of the shelf  9  also rests on this strip-shaped guiding lay-on  53  in the use position of the first shelf  9 . The ramp  54  and the section  55  are also associated with it. By this strip-shaped guiding lay-on  53 , as it extends and geometrically forms, is also allowed that the first shelf  9  is simpler to handle with respect to its shift. A more jamming-free and strutting-free shift is allowed. In the front area of the first shelf  9 , laterally protruding guiding pins are no longer required. In the use position according to  FIG. 2 , the shelf  9  is therefore also movable relative to the carrier frame  16  at least in the front area in an embodiment. In this respect, it can be easily lifted. Thereto, the guiding pins  57   a  and  57   b  form a rotational axis or pivot axis, around which the first shelf  9  can also be pivoted in the use position. In this respect, easy lifting can in particular be effected. Thereby, moving the first shelf  9  from its use position towards the non-use position according to  FIG. 3  is also facilitated. The initiation this shifting process is also simplified by this configuration. Because, the first shelf  9  can first be easily lifted on the front side starting from the use position shown in  FIG. 2  in this context. Thereby, the following shift of the first shelf  9  is simplified. Leading out the guiding pins  57   a  and  57   b  from the receiving core  58  is thereby facilitated. 
     Upon shifting the first shelf  9 , this first shelf  9  rests on these strip-shaped guiding lay-ons  53 . In an embodiment, this is effected by the front edge profile  12 . It can also be provided that the base plate  10  additionally directly rests on this strip-shaped guiding lay-on  53 . 
     In the surface area of this strip-shaped guiding lay-on  53 , the first shelf  9  is arranged completely exposed towards the top and thus viewed in vertical direction. This means, as it was already explained above, that this strip-shaped guiding lay-on  53  does not comprise an overlying counterpart such that an upwards closed guiding groove is not formed. Upon shifting, a first length half L 1  ( FIG. 5 ) of the first shelf  9  is only guided by resting on this strip-shaped guiding lay-ons  53  of these two side bars  17  and  18 . This front length half L 1  does not comprise lateral guiding pins or the like as the rear length half L 2  of the first shelf  9  comprises. 
     Moreover, the guiding  31  comprises a rear guiding section  59  in an embodiment. This rear guiding section  59 , as it is illustrated at the side bar  17  in  FIG. 4 , is arranged below the second shelf  13  in vertical direction (y-direction) of the shelf assembly  8 . Thereby, the first shelf  9  can be shifted below the second shelf  13  also guided in this respect. The rear guiding section  59  directly adjoins to the guiding lay-on  53 . The rear guiding section  59  is a constituent of the first guiding part  31   a.    
     In an embodiment, it is provided that the first shelf  9  can be rearwards shifted out of the carrier frame  16  in depth direction of the shelf assembly  8 . Thus, for example starting from the non-use position of the first shelf  9  in  FIG. 3 , this first shelf  9  can be rearwards shifted out of the carrier frame  16 . Thereby, it can also be completely removed from the carrier frame  16 . Thereby, the cleanability of the first shelf  9  is for example separately possible. Improved cleaning of this component is thereby allowed. 
     In  FIG. 7 , a partial section of the shelf assembly  8  according to  FIG. 2  is shown in a vertical sectional representation. Here, the sectional plane is the y-z plane. As is apparent, the rear edge profile  11  comprises a rear wall  60 . This rear wall  60  is obliquely oriented. An upper end  60   a  of this rear wall  60  is farther forward than a lower end  60   b  viewed in depth direction. In an embodiment, it is provided that a front wall  61  of the front edge profile  15  is obliquely inclined. In an embodiment, an upper end  61   a  of this front wall  61  is positioned farther forward viewed in depth direction than a lower end  61   b . As is apparent in  FIG. 7 , the rear wall  60  and the front wall  61  are inclined in the same direction. In an embodiment, a distance between this rear wall  60  and the front wall  61  is set in the use position. Thus, a crack  62  is formed. It can be configured relatively small in this respect. If such an inclined position of the rear wall  60  and/or the front wall  61  would not be formed, the crack  62  would be considerably larger measured in depth direction. This would be disadvantageous with regard to falling-through of storage parts or the like. By this specific geometry of the rear wall  60  and/or the front wall  61  and thus the shaping of the crack  62  resulting from it, an improved concept can be provided in this respect. By this crack  62 , a specific venting slit can then also be formed. The passage of the air can also be effected preset in a certain orientation to some extent by this specific inclination. 
     In an embodiment, it is provided that the rear edge profile  11  is attached to the base plate  10  by a snap-fit connection  63 . In an embodiment, it can be provided that the front edge profile  15  is attached to the base plate  14  by a corresponding snap-fit connection. 
     In  FIG. 8 , the arrangement of the components according to  FIG. 7  is shown in a corresponding vertical sectional representation. However, a vertical sectional plane different from  FIG. 7  is chosen in  FIG. 8 . It is parallel to  FIG. 7 . In  FIG. 8 , a vertical sectional representation through the guiding pin  57   a  is shown in this respect. The receiving core  58  is also shown in  FIG. 8 . The receiving core  58  is bounded towards the front by a front wall  64   a . A stop for the guiding pin  57   a  is formed by the front wall  64   a . In an embodiment, the receiving core  58  is bounded towards the bottom by a base wall  64   b . The guiding pin  57   a  rests on this base wall  64   b  in its final position when it is introduced in the receiving core  58 . 
     In  FIG. 9 , a representation of a partial section of the shelf assembly  8  according to  FIG. 2  is shown in a plan view. 
     In  FIG. 10 , the shelf assembly  8  is shown in a further vertical sectional representation. In contrast to the representation in  FIG. 3 , in which the non-use position of the shelf  9  is illustrated, this shelf is already shifted out of the carrier frame  16  slightly further to the rear in  FIG. 10 . In this context,  FIG. 10  shows the possibility already set forth above of completely rearwards removing the shelf  9  out of the carrier frame  16 . 
     Moreover, a front end  65  of the first side bar  17  of the carrier frame  16  is shown in  FIG. 10  as already apparent in  FIG. 3  and  FIG. 4  as well as also in  FIG. 2 . The front end  65  is formed tapered. The front end  65  comprises a neck  66  protruding to the front. This neck  66  has a thickness d. In an embodiment, this thickness d corresponds to the thickness d 1  ( FIG. 5 ) of the first shelf  9 . In an embodiment, the thickness d 1  is the thickness of the front edge profile  12 . Here too, it is provided in corresponding configuration that the second side bar  18  is also correspondingly configured. 
     In conclusion, it is to be mentioned again that the configuration of the side bar  17 , as was explained above and amplified based on embodiments, can each be correspondingly provided for the second side bar  18  in an embodiment.
