Description

Door for a domestic refrigeration appliance with a special lower edge strip and domestic refrigeration appliance

Technical Field

One aspect of the invention relates to a door for a domestic refrigeration appliance. The invention also relates to a domestic refrigeration device comprising such a door.

Background

A door with a trim strip is known from DE 10 2015 206 862 A1. The trim strip is upwardly restrained to a hand grip in the side edge of the door. The edge-closing lath is connected with the sectional material for limiting the hand digging.

A known lower trim strip 100 for a door of a domestic refrigeration appliance is known from a perspective view in fig. 1. The molding 100 has an elongated or beam-shaped base part 101. The welt strip 100 has a longitudinal axis a'. In the direction of the longitudinal axis a', the edging strip 100 has a first end 101 and an opposite second end 102. The

coupling structures

103 and 104 are formed on the first end 101 and on the second end 102, respectively. The coupling structures are provided as specified as edge profiles, which are independent of the coupling structures, of the respective door and are mechanically coupled directly. The profile forms the narrow side of the edge side of the door. As can be seen, the coupling structure 103 has a contact wall 105. The contact wall extends in the height direction (y direction) from the base part 101. The contact wall is provided as intended for the at least partial outer application or abutment thereon of a not shown edging profile. As can be seen in fig. 1, the contact wall 105 is formed as a simple U-shaped piece. This can also be seen in the enlarged view in fig. 2, in which fig. 2 the end 102 is shown. Furthermore, the contact wall is formed so as to be set back in relation to the front side and the rear side (viewed in the depth direction) in the depth direction (z direction) oriented perpendicular to the longitudinal axis a'. In the case of such a contact wall 105, the tightness of the foam at the interface between the contact wall 105 and the edging profile independent of the contact wall is limited. In this regard, a sectional view of the edging strip 100 on the end 102 is shown in fig. 3. Here, a trimming profile 107, which is independent of the trimming strip, is connected to the trimming strip 100. As can be seen, in the horizontal cross-sectional view, in which the cross-sectional plane extends in the x-z plane, the contact wall 106 is interrupted. In the context of the present application, such a face region of the coupling structure is understood as a contact wall 106: the surface region is provided as intended for applying or bearing against the edge-closing profile 107 at least in regions. This also means that: only such a surface area in the height direction can be understood as a contact wall: the surface region is provided as intended for overlapping the edge profile 107 in the height direction. The sectional view according to fig. 3 is therefore to be understood only in this position: in this position, the contact wall 106 is formed in a height direction with such an overlap with the final assembled edge profile 107. As can be seen in fig. 3 for this purpose, the contact wall 106 is not continuous but interrupted in the defined horizontal sectional view. It is in this front corner region 108 on the end 102 that a circumferential or extensive interruption is achieved in this respect. In this connection, the edging profile 107 is arranged completely independently (freistehend) there. In particular, there is thus at least an exit potential for the insulating foam at this location.

Fig. 4 shows a perspective view of a further exemplary embodiment of a trimming strip. The trimming strip is formed here as a further embodiment for the lower trimming strip 100.

In the trim strip 100 according to fig. 1, the trim strip 100 is provided in a door in which the trim profile is used as a limiting wall for a hand opening formed on a side edge of the door. The trim strip 100 according to fig. 4 is used in contrast in doors which do not have such a grip on the side edge of the door.

As can be seen here in fig. 4, the contact wall 105 is merely designed as a thin vertical strip. This also results (in the horizontal sectional view in fig. 6) in a circumferential or wide region in which the edge-closing profile 7 is exposed and, in the plan view shown in fig. 6, likewise forms the case in which the contact wall is formed interrupted in the horizontal sectional configuration. Furthermore, an interface region is formed locally, in which the isolating foam cannot be avoided from coming out sufficiently reliably.

Moreover, it is in this case that a corresponding problem exists at this front corner region 108 at the end 102 shown here.

The door of the domestic refrigeration appliance is filled with thermally insulating foam. In the case of the introduction of the foam, the latter expands and can come out at the interface between the door parts. It is therefore known to provide such a joint with, for example, adhesive tape or other manufacturing aids in order to prevent foam from coming out during the manufacturing process. In the case of complex-shaped interfaces, this can only be achieved partially conditionally. Furthermore, such auxiliary means can only be installed conditionally in the case of interfaces that are difficult to access.

Disclosure of Invention

The present invention is based on the idea of providing a door for a domestic refrigeration device in which the interfaces between the individual component parts are better coupled to one another in order to achieve a higher foam tightness. Accordingly, it is also an object to provide a domestic refrigeration appliance comprising such a door.

This object is achieved by the door and the domestic refrigeration appliance according to the invention.

One aspect of the invention relates to a door for a domestic refrigeration appliance. The door has an outer wall. The door also has an edge profile on the edge side. The edge-closing profile on the edge side extends in the height direction. In other words, the edge-side profile is an elongated profile or profile rail oriented in the height direction. The door also has an end-side trim strip that is separate from the trim profile and from the outer wall. The edge strip has an elongated, in particular beam-shaped, base part. The edging strip has a longitudinal axis. The longitudinal axis is oriented in the width direction of the door. The edge strip is therefore likewise an elongate component which extends in the width direction. In the direction of the longitudinal axis, the edging strip has a first end and an opposite second end. A coupling structure, in particular formed in one piece with the base part, is formed on at least one end. The coupling structure is provided for direct mechanical coupling to the edge profile on the edge side. The coupling structure has a contact wall extending upward from the base member in a height direction of the door. The coupling structure is provided for at least partially applying or bearing on the outside the edge-folding profile and/or for at least partially directly adjacent positioning of the edge-folding profile. This means in particular that: viewed in the height direction of the door, the contact wall is to be determined and understood in such a way that it is provided in accordance with the regulations with regard to the overlap with the edge trim provided in the final assembled state in this height direction. In the context of this understanding, the following regions of the base element and of the edging profile should also not belong to the contact wall: these regions are arranged in the height direction in the final assembled state of the edge trim without overlapping the contact wall. Furthermore, it is provided that the contact wall does not have to be directly contacted over the entire surface by the edge-trimming profile in the assembled state, or that the edge-trimming profile does not have to be directly applied to the contact wall over the entire surface on the outside. The contact wall is also provided such that, in the final assembled state, a slight distance can be provided between the contact wall and the edge profile, in particular at least in regions.

Viewed perpendicularly to the longitudinal axis, but in the horizontal direction and thus not in the height direction of the door, the contact wall has a front wall region, a middle wall region adjoining the front wall region and a rear wall region adjoining the middle wall region. In the depth direction, the front wall region, the middle wall region and the rear wall region are formed without interruption in a horizontal cross section at least one height position. The horizontal section is formed in a plane which is developed in the depth direction and the width direction of the door. The horizontal cross section is formed here at a height position at which the contact wall is formed. The contact wall is thus formed at a height position at which, in the final state of assembly, a cross section is provided through the contact wall and also through the edge-trimming profile present there and overlapping the contact wall.

By means of this embodiment of the contact wall, which is designed without interruption at this point in the particular horizontal cross section, undesired leakage points, at which the thermal insulating foam can emerge from the intermediate space of the door at the interface between the trim profile and the contact wall during the foaming process, can be avoided or at least significantly reduced. The particular design of the contact wall with the front, middle and rear wall regions and the shape thereof in the horizontal section, which is completely free of voids, make it possible to better avoid such an insulating foam coming out at all points, in particular also at the particular front corner region. That is, by this configuration of the contact wall, a wall labyrinth without interruption in the horizontal section can be formed. This makes it possible to achieve particularly advantageously: in the foaming process, the foam can possibly reach into the intermediate space between the contact wall and the edge strip, but due to the uninterrupted structure and the small distance of the edge strip from the contact wall at any time, it is achieved that the foam cannot escape to the outside. Since, by means of this particular uninterrupted wall labyrinth, the foam disappears or has no consequence if it can enter the interface region at all, so that it solidifies already before it can come out of the door on this interface region between the contact wall and the edging profile. In other words, with this particular design of the contact wall, a continuous and gap-free wall cross-section line is formed in the horizontal cross-section. The wall section line is completely formed from the front side to the rear side of the edging profile, viewed in the horizontal direction perpendicular to the longitudinal axis. The uninterrupted cross-sectional line therefore extends without play from the front side of the edging profile to the rear side of the edging profile. This also forms a contact wall which is arranged and formed in the same direction in the corresponding extent of the edge profile.

In particular, in one embodiment, it is provided that the uninterrupted design of the contact wall is implemented not only at one height position, but also, viewed in the height direction, over at least one consecutive height section. The height section may have a height of at least 0.5 cm. In particular, it can be formed in a height section which can extend over a height of between 0.5 cm and 10 cm. However, in this connection, the height section may also be higher.

In one embodiment, in the horizontal cross section, the contact wall with the front wall region, the middle wall region and the rear wall region and the edge profile are each formed without interruption. The edge profiles therefore also have no gaps in the overlap region and in the horizontal cross section. This again improves the special wall labyrinth of fine mesh, which extends almost without interruption from the front side to the rear side of the edging profile.

In one embodiment, in the horizontal cross section, the contact wall with the front wall region, the middle wall region and the rear wall region and the edge profiles have the same profile over their entire length. In particular, in this horizontal section, the contact wall and the edge profile are arranged so as to extend parallel or substantially parallel to one another over the entire length. This is another very advantageous embodiment. Since, on the one hand, the mechanical stability of the interface between the edging profile and the contact wall can be improved in this respect. However, it is particularly advantageous to form the shape identity or to substantially form the shape identity between the two individual components from the front side to the rear side. This improves, on the one hand, at least the local mutual contact between the inner side of the edging profile and the outer side of the contact wall. On the other hand, only a minimum spacing is formed in the regions which do not form the abutment. The minimum spacing, viewed in the plane of the horizontal cross section, may be in particular less than 5 mm at all positions. The formation of such a small gap with such a minimum spacing at any time makes it possible, in combination with the other special features already mentioned, to very quickly produce the collapse of the foam which enters when necessary and to prevent the foam from bulging out on the interface.

In one embodiment, the contact wall with the front wall region, the middle wall region and the rear wall region has a coherent multiple U-shape in horizontal cross section. In particular, a design with a U-shaped section is formed here. In particular, a shape or shape progression is realized which is formed only by the three U-shaped portions. This particular shaping of the contact wall contributes to the above-mentioned advantages to a particular extent. On the one hand, a corresponding stabilization is achieved thereby. On the other hand, a wall labyrinth is formed to a particular extent, which, by means of an uninterrupted design, prevents the foam from bulging outward on the interface in a particularly effective manner in the horizontal cross section by means of a particularly similar or identical shape course of the edging profile. The plurality of U-shaped sections are continuous or aligned with one another and are visible in the horizontal direction perpendicular to the longitudinal axis of the trim strip, in particular in the depth direction of the door. It can therefore be said accordingly: in horizontal section, three U-shaped sections are formed following each other in the direction from the front side to the rear side of the edging strip. In particular, the three U-shaped sections are directly aligned with each other. In this connection, a particularly specific serpentine shape of the contact wall is thus formed. The serpentine profile extends in the individual profile from the front side to the rear side of the edging profile to a particular extent.

In one embodiment, the three U-shaped sections are alternately oriented with their U-openings, viewed in the horizontal cross-section. This means that: viewed perpendicular to the longitudinal axis in this horizontal direction, the first U-shaped section is oriented with its U opening toward one end of the edging strip. Subsequently, the further second U-shaped section following in the direction perpendicular to the longitudinal axis is rotated by 180 ° or substantially 180 ° in the horizontal sectional plane in comparison thereto. The U-shaped opening thereof is thus oriented, viewed in the direction of the longitudinal axis thereof, toward the opposite end of the edging strip. The third U-shaped section following in a direction perpendicular to the longitudinal axis is again oriented in the horizontal sectional plane like the first U-shaped section. The U opening of this third U-shaped section is thus again directed towards the following end of the edging strip: the U opening of the first U-shaped section is also towards the end.

In one embodiment, the mid-wall region has a U-shaped section. In one aspect, a front wall region is directly connected to the U-shaped section, which front wall region forms or has a freely projecting U-leg of another continuous U-shaped section. It is therefore provided that the U-leg is not only a component of the U-shaped section of the central wall region but at the same time also the U-leg with the front wall region of the U-shaped section thereof.

In a further embodiment, the central wall region has a U-shaped section to which the rear wall region is connected, the rear wall region forming a freely projecting U-leg of the other U-shaped section. In this respect, the U-side of the middle wall region also forms the U-side of the rear wall region.

In particular, the front wall region and its U-shaped section form a closed wall structure of the contact wall in a horizontal section at a front corner region of one end, viewed in a direction perpendicular to the longitudinal axis of the edge strip.

In particular, a special wall labyrinth between the contact wall and the edge profile overlapping the contact wall in the height direction can thus be realized in this corner region, which particularly advantageously prevents foam from escaping.

In one embodiment, the front wall area has the same first height as viewed in the height direction. This means that: the entire front wall area is of equal height in the direction of its longitudinal extension. In one embodiment, the first height is greater than a height of the back wall region. The back wall region has a second height. In one embodiment, the second height is formed identically over the entire length of the rear wall region. The front wall region is formed higher than the rear wall region by this configuration. This applies in particular to the respective total length of the mentioned regions. By means of this stepped design of the contact wall, a further improvement in the foam tightness can be achieved with regard to the individual positioning of the edge profile and the respective critical interface region between the edge profile and the contact wall.

In one embodiment, the first height is greater than 3 cm, in particular between 3 cm and 8 cm. In one embodiment, the second height is between 2 centimeters and 6 centimeters. By means of this relatively large dimension, a relatively large overlap height between the contact wall and the edging profile in the height direction of the door can be achieved. In addition to the above-described shaping and the design of the contact wall from the front side to the rear side of the edging strip without interruption in horizontal section, a foam-tight seal can be achieved at the interface to a particular extent.

Preferably, the central wall region is formed in a stepped manner. In particular the mid-wall region has exactly one discontinuous wall height step. In particular, it is a vertical stepped edge. Furthermore, the above-mentioned advantages can be positively supported by the special geometry of the contact wall at the special position.

In one embodiment, the trim strip is a lower trim strip viewed in the height direction of the door.

In a further embodiment, it can be provided that the front wall region, the middle wall region and the rear wall region have a common identical height, viewed in the height direction of the door. This means that: the front wall region, the middle wall region and the rear wall region each have the same height, viewed over their entire length, and also have this same height relative to one another. In this regard, the upper edge of the contact wall has no wall height variation as viewed across these three regions.

In one embodiment, the contact wall has a single U-shape in horizontal cross-section. It is advantageous if the contact wall does not have to be formed with multiple corners and the edge profiles are formed without corresponding multiple corners. If the edge-folding profile is a limiting wall for the hand-lifting, which limiting wall is formed in the narrow side region of the door, then a multiple-angled design of the edge-folding profile is provided. If such a hand is not provided on such an edge side of the door, a simple shaping of the edge strip and thus of the edge strip is possible, in particular in the region of the interface with the edge strip. In one embodiment, therefore, the only U-shaped profile in this horizontal section is sufficient for the contact wall.

In one embodiment, the contact wall has a horizontally extending contact wall strip which is formed without interruptions over all wall regions. The contact wall strip is formed on the carrier wall of the edge strip and the contact wall projects outwardly beyond the outer side of the carrier wall. In this embodiment, it is therefore sufficient to: only one such contact wall strip is provided for the possible application of the inner side of the edging profile as required. The contact wall strip is narrower in height than along its strip longitudinal axis, which is oriented in the horizontal direction. In particular, the contact wall strip is formed directly on the upper edge of the contact wall. The contact wall strip thus also forms the upper end of the support wall, for that matter almost or as it were.

Another aspect of the invention relates to a domestic refrigeration appliance having a door according to the above aspect or an advantageous embodiment thereof. The domestic refrigeration device can be, for example, a refrigerator or freezer or a combined refrigerator and freezer. A domestic refrigeration appliance is configured for storing and preserving food items. The domestic refrigeration device has at least one receiving space for food products. The receiving space may be a refrigerating compartment or a freezing compartment.

The door has, for example, a wall made of metal as an outer wall. This may be a sheet metal wall, for example. Further, the door has an inner wall. The inner wall may also be referred to as a liner. Typically, the inner wall is made of plastic. A thermal insulation material, in particular an insulation foam, is introduced into the intermediate space between the outer wall and the inner wall. On the side, the door is limited on the edge strip by the already mentioned edge profile. In the upper and lower part, the door is each limited by a trim strip which has likewise been elucidated.

The directional statements "in width direction", "in height direction", "in depth direction", "up", "down", "front", "rear", "outer", "inner" etc. for the door and the domestic refrigeration appliance relate to the state of the domestic refrigeration appliance as established for conventional applications, the door of the domestic refrigeration appliance being arranged at the front with respect to the observer and the rear side at the front.

Detailed Description

An embodiment of the domestic refrigeration device 1 is shown in a perspective simplified view in fig. 7. The domestic refrigeration device 1 can be, for example, a refrigerator or freezer or a combined refrigerator and freezer. The domestic refrigeration appliance 1 is configured for storing and preserving food products. The domestic refrigeration appliance has a housing 2 in which at least one receiving space 3 for food products is formed. A door 4 is arranged on the housing 2 so as to be pivotable, so that the receiving space 3 is closable from the front or front.

The door 4 is formed in multiple parts.

A perspective partial view of one embodiment of door 4 is shown in fig. 8. The door 4 has an outer wall 5. The outer wall 5 may be formed from sheet material. The door 4 furthermore has an inner wall 6, which is not visible in fig. 8 and is provided with reference symbols. This inner wall 6 may also be referred to as the inner lining of the door 4. Which in the closed state of the door 4 faces the inner space 3. The outer wall 5 and the inner wall 6 are separate members from each other. A thermal insulation material 8, in particular an insulation foam, is introduced into the intermediate space 7 between the outer wall 5 and the inner wall 6.

The door 4 furthermore has narrow side edges, of which only one narrow side edge 9 is shown in fig. 8. In this exemplary embodiment, the narrow side edges 9 are formed as edge-sided trimming profiles 10. Thereby laterally limiting the intermediate space 7. In the exemplary embodiment shown, the edge profile 10 is at the same time a limiting wall 11 of a hand grip 12. The hand cutout 12 is therefore formed in the door on the side edge 9 or integrated into the side edge.

The edge profile 10 is formed in one piece with the outer wall 5 in the present exemplary embodiment. The edging profile is a separate component from the inner wall 6. It is also possible that the edging profile 10 and the outer wall 5 are separate parts.

The edge strip 10 can be formed in one piece. For example, the edge strip can be made of sheet metal.

The door 4 furthermore has a trim strip 13. The trimming strip is here a lower trimming strip. This can be seen looking in the height direction of the door 4. The door 4 furthermore has a further trim strip 14. The other edge-closing lath is an upper edge-closing lath.

Fig. 9 shows an embodiment of the lower molding 13 in a perspective view. The lower edge strip 13 is formed in one piece. The lower edge strip can be made of plastic, for example. The edge strip 13 is an elongate component.

The edging strip 13 has a base part 15. The base element 15 is formed in a beam-like manner. The edging strip 13 has a longitudinal axis a. The trim strip is oriented in the width direction (x-direction) of the door 4. The edging strip 13 has a first end 16 and an opposite end 17, viewed along the longitudinal axis a. In the depth direction (z direction) and thus in the horizontal direction perpendicular to the longitudinal axis a, the edging strip 13 has a front side 18 and for this purpose an opposite rear side 19.

A coupling structure 20 is formed on the end 16. The coupling structure has a contact wall 21. The contact wall 21 extends upward as viewed in the height direction. The contact wall is formed with multiple corners. The contact wall 21 extends continuously from the front side 18 to the rear side 19. The contact wall 21 is, as viewed in the height direction, a wall region which is provided as intended for an overlapping arrangement with the edge strip 10.

A corresponding coupling structure 22 with a contact wall 23 is formed on the opposite end 17.

Viewed in the depth direction and thus in the horizontal direction perpendicular to the longitudinal axis a, the contact wall 21 has a front wall region 24, a middle wall region 25 and a rear wall region 26. The contact wall 23 is formed accordingly.

As can be seen in fig. 10 in the enlarged view of the edging strip 13 in the region of the end 16, the contact wall 21 extends from the base 27 of the base part 15 in the height direction. In particular, the base 27 has a top wall 28, from which top wall 28 the contact wall 21 extends upwards.

The contact wall 21 is provided as intended for applying the edge strip 10 thereto at least in regions on the outside. The edge trim 10 has the already described front wall region 24. The front wall region 24 is a U-shaped section 29 here. The U-shaped section 29 has a U-side 29a. The U-shaped edge is a freely protruding U-shaped edge. The direction of the U-curl perpendicular to the longitudinal axis a is the forwardmost section of the contact wall 21. The U-shaped edge faces the opposite end 17 in its freely convex orientation. Furthermore, the U-shaped section 29 has a second U-shaped side 29b. This second U-side is also the U-side 30a of the middle wall area 25. The central wall region 25 is also formed in this exemplary embodiment as a U-shaped section 30. The U-shaped section 30 has another U-side 30b. Furthermore, a base 30c is formed, which here completes the U-shaped region 30.

The rear wall region 26 is likewise in this embodiment formed as a U-shaped section 31. The U-shaped section has a free projecting U-edge 31a. Furthermore, the U-shaped section has a further U-shaped edge 31b. The U-side 30b is also the U-side 31b.

As can be seen in the case of this multiple U-shape of the contact wall 21, the U-shaped regions 29 and the U-shaped openings of the U-shaped regions 31 are oriented in the same direction, i.e. in this case toward the opposite end 17 of the edging strip 13. In contrast, the U-shaped opening of the U-shaped section 30 located in between them in this respect faces away from the opposite end 17. It can also be seen that U-side 30a corresponds to U-side 29b. U-side 30b corresponds to U-side 31b. The free projecting U-edge 31a is oriented towards the opposite end 17. Furthermore, it is also visible in the embodiment in fig. 10 that the contact walls 21 do not have the same height. In this connection, the front wall region 24 is formed over its entire extent with the same height, i.e. the first height h1. In contrast, in this embodiment, the rear wall region 26 is configured to have a second height h2. The second height h2 is less than the first height h1. The heights h1 and h2 are measured from the top wall 28. In this exemplary embodiment, the rear wall region 26 is formed over its entire extent with the same height h2. The central wall region 25 with its U-shaped section 30 shown here has a varying height. In this regard, in this embodiment, the U-side 30a and the base side 30c adjacent thereto have a height h1. A height offset 32 is formed in the transition between the base edge 30c and the other U edge 30b. The discontinuous or discrete steps are considered to be the only step change over the entire length of the contact wall 21. A height jump from the height h1 to a lower height h2 is formed.

Fig. 10 also shows that the design of the webs 33 spaced apart from the contact wall 21 is realized on this end 16 in an outward direction. The webs 33 are, as viewed in the height direction, much lower, in particular smaller, than the contact walls 21 by a height h2. The web 33 is formed over its entire length at a distance from the contact wall 21. Thereby, a gap 34 is formed between the outside of the contact wall 21 and the inside of the tab 33. In the final assembled state, the lower edge 35 of the edging profile 10 projects into this slot 34.

In this case, it is provided that, in a sectional plane formed by a horizontal section, the contact wall 21 is formed completely without interruption at least in regions in its height. In this way, in the present exemplary embodiment, in a horizontal section through the x-z plane, the contact wall 21 can be provided as a completely uninterrupted contact wall 21 at a height position at which the second height h2 is formed. In the height direction, the edging profile 10 overlaps the contact wall 21. In particular, this also applies in the region in which the height h2 is formed. In the exemplary embodiment shown here, the contact wall 21 is designed in particular to make it possible to produce a profile 10 which has a hand grip 12 in one piece. In particular, the shape and thus the shape progression of the contact wall 21 is adapted to the shape of the edge strip 10, in particular in the region of the hand grips 12. In particular, a corresponding shaping of the trimming profile 10 is achieved in this respect over the entire extent of the contact wall 21. In particular in the region in which the contact wall 21 is formed without interruption over its entire length in horizontal section, the correspondingly visible shape profile of the edge-trimming profile 10 in cross section is also formed identically.

An advantageous wall labyrinth is thus formed at this interface between the edging profile 10 and the contact wall 21.

The view of fig. 10 is shown in fig. 11 in a perspective view different from that of fig. 10. As can be seen here, it is precisely in the front corner region 36 of the contact wall 21 that the contact wall 21 is designed continuously without interruptions. This applies in particular to the height h2 of the contact wall 21. In general, therefore, it can be said that in a horizontal section, which is at a height level in the region between the lower ends of the contact walls 21, which end, for example, directly on the top wall 28 and extend from there up to the height h2, the contact walls 21 are formed completely without interruption.

Fig. 12 shows in this respect: a perspective sectional view of the arrangement according to fig. 10 with the trimming profile 10 in the final assembled state arranged on the lower trimming strip 13. As can be seen here, the trimming profile 10 is guided in the slot 34, in particular with its lower edge 35. The identically formed shape course between the contact wall 21 and the run-in profile 10 is visible over the entire length in this horizontal section according to fig. 12. As can be seen in fig. 12 in a perspective horizontal section, the outer wall 5 here rests directly on the outside of the front wall region 24, in particular on the outside of the U-leg 29a. However, in one exemplary embodiment it is also possible to form the spacers here.

Accordingly, for example, the rear bead (Umbug) 37 of the edging profile 10 can rest directly on the outer side of the contact wall 21, in this case on the outer side of the U-leg 31a. However, it is also possible to arrange the bead 37 at a distance from the U-leg 31a. This is shown in fig. 12. In the exemplary embodiment shown here, a spaced-apart arrangement between the edge strip 10 and the contact wall 21 is also formed. In this connection, however, a corresponding spacing is formed in the horizontal plane, which spacing is less than 5 mm everywhere. The design in this respect makes it possible to realize an arrangement labyrinth for a uniform shape between the contact wall 21 and the run-up profile 10.

It can be provided that the spacing between the bead 37 and the U-leg 31 and/or the spacing between the outer wall 5 and the U-leg 29a is smaller than the spacing between the remaining bead former 10 and the remaining contact wall 21.

Fig. 12 shows a horizontal section, which is formed above the height h2 and in the region of the height h1, for reasons of clarity and for the visibility of the wall height h2. This is merely for better visibility of the individual components with respect to the perspective view. Since it is also visible here that a completely uninterrupted design of the contact wall 21 is achieved over the entire length in the region of the height h2 in the horizontal cross section.

Fig. 13 shows a perspective view of a further exemplary embodiment of a trimming strip, which is also a lower trimming strip 13 here. In one embodiment, the trimming strip 13 is made in one piece, in particular of plastic. The edge strips 13 according to fig. 13 are in particular components of the door 4, which do not have a hand grip 12 on the side edges.

Here, too, a contact wall 21 is formed, as can be seen on the end 17 in fig. 13. The contact wall 21 is realized here as a contact wall strip 21a. Furthermore, in a horizontal section, which is formed in the height direction at the height of the contact wall strip 21a, an uninterrupted design of the contact wall 21 is formed over the entire length of the contact wall. In addition, a corresponding wall region 21b is formed here, which is realized flush with the contact wall strip 21a. They are oriented in the height direction. This is also shown in fig. 14, fig. 14 showing an enlarged portion of the view in fig. 13. In fig. 15, the trimming strip 13 is shown in a perspective view in the assembled state with the trimming profile 10. Furthermore, a lower edge 35, which is accordingly not visible here, is introduced into the slot 34. This arrangement is shown here.

Fig. 16 shows an embodiment of the upper edging strip 14 in a perspective view. In terms of construction, the trimming strip in the region of the coupling structure is correspondingly as shown in the exemplary embodiment in fig. 13 to 15. Here, a contact wall 21 with a contact wall strip 21a is realized. An enlarged view is shown in this regard in fig. 17. Here, a carrier wall 38 is shown. Contact wall strips 21a are molded or formed to project outwardly on the carrier walls 38. This applies correspondingly to the wall region 21b.

Fig. 18 also shows a perspective view of the trimming strip 14 in the assembled state with the respective trimming profile 10. In a horizontal section, which is formed at a height level in the region of the height of the contact wall strip 21a, in this respect an uninterrupted contact wall 21 is produced in this horizontal section over the entire length of the contact wall. In this connection, the contact wall strips 21a are also arranged and provided in a defined manner in a height region in such a way that they overlap the edge strip 10 in the height direction in the assembled state.
