Description

One aspect of the invention relates to a door for a household refrigeration appliance according to the preamble of claim 1. The invention also relates to a household refrigeration appliance with such a door.

From the DE 10 2015 206 862 A1 a door with an end strip is known. At the top, this delimits a recessed grip in a side edge of the door. The end strip is connected to a profile that delimits the recessed grip.

In 1 a known lower end strip 100 for a door of a household refrigeration appliance is known in a perspective representation. This end strip 100 has an elongate or bar-shaped base part 101 . The end strip 100 has a longitudinal axis A`. In the direction of this longitudinal axis A′, the end strip 100 has a first end 101 and an opposite second end 102 . A coupling structure 103 or 104 is formed both at the first end 101 and at the second end 102 . This is intended for direct mechanical coupling with a separate, edge-side closing profile of the door. This end profile forms the edge narrow side of the door. As can be seen, the coupling structure 103 has a contact wall 105 . This extends from the base part 101 in the height direction (y-direction). It is intended for at least regionally external application of the terminating profile, not shown. As in 1 can be seen, this contact wall 105 is designed as a simple U. This is also shown in the enlarged view in 2 can be seen, in which the end 102 is shown. In addition, in a depth direction (z-direction), which is oriented perpendicularly to the longitudinal axis A′, this contact wall is set back from a front side and a back side (viewed in the depth direction). With a contact wall 105 of this type, the foam tightness at this interface between the contact wall 105 and the end profile that is separate therefrom is limited. In this context, in 3 a sectional view of the end strip 100 at the end 102 is shown. A separate end profile 107 is connected to the end strip 100 here. As can be seen, this abutment wall 106 is interrupted in this horizontal sectional view, in which the sectional plane runs in the xz plane. In the context of the application, a contact wall 106 is understood to be such a surface area of the coupling structure that is intended for at least regional application of the closing profile 107 . This also means that in the vertical direction only such a surface area can be understood as a contact wall which is intended to overlap with the end profile 107 in this vertical direction. A sectional view according to 3 is therefore only to be understood at such a point at which such an overlap is formed in the height direction between the contact wall 106 and the end profile 107 mounted in the final state. How to in 3 as can be seen, in this defined horizontal sectional view, the abutment wall 106 is not continuous, but discontinuous. In this regard, a circumferential interruption is implemented precisely in a front corner region 108 at this end 102 . In this regard, the end profile 107 is arranged completely free-standing there. In particular, at least at this point, there is therefore a potential exit point for the insulating foam.

In addition, in 4 shown in a perspective view another embodiment of an end strip. This is formed here as a further exemplary embodiment for a lower end strip 100 .

For the end strip 100 according to 1 this is provided for doors in which the end profile is intended to serve as a boundary wall for a recessed grip that is formed on this side edge of the door. The bottom bar 100 according to 4 on the other hand, is used on a door that does not have such a recessed grip on this side edge of the door.

As also here in 4 can be seen, the contact wall 105 is only formed as a thin vertical strip. This also creates, according to the horizontal section in 6 , a peripheral zone where the finishing profile 7 is exposed and in which in 6 shown plan view is also formed a situation in which the contact wall would be formed interrupted in a horizontal sectional configuration. An interface area would also be formed locally, in which the escape of insulating foam could not be avoided with sufficient certainty.

Here, too, there is a corresponding problem area precisely at such a front corner region 108 at this end 102 shown here.

A door of a household refrigerator is filled with a thermally insulating foam. When this foam is introduced, it swells and can escape at interfaces between door components. It is therefore known that such interfaces are provided with adhesive tapes or other auxiliary manufacturing elements, for example to prevent the foam from escaping during this manufacturing process. In the case of complex interfaces, this is sometimes only possible to a limited extent. Even with interfaces that are difficult to access, such aids can only be attached to a limited extent.

It is the object of the present invention to create a door for a household refrigeration appliance in which interfaces between separate structural components are coupled together in an improved manner in order to achieve greater foam tightness. Accordingly, it is also an object to create a household refrigeration appliance with such a door.

This object is achieved by a door and a household refrigeration appliance according to the independent claims.

One aspect of the invention relates to a door for a household refrigeration appliance. The door has an outer wall. In addition, the door has an edge profile. This edge-side end profile extends in the height direction. It is therefore an elongated profile rail oriented in the vertical direction. In addition, the door has an end strip that is separate from the end profile and the outer wall. The end strip has an elongate, in particular bar-shaped, base part. The end strip has a longitudinal axis. This longitudinal axis is oriented in the width direction of the door. The end strip is therefore also an elongate component which extends in the width direction. In the direction of the longitudinal axis, this end strip has a first end and an opposite second end. At least one end is formed with a coupling structure, in particular formed in one piece with the base part. This coupling structure is intended for direct mechanical coupling to the border profile. The coupling structure has an abutment wall which, starting from the base part, extends upwards in the height direction of the door. The coupling structure is intended for at least partially placing the terminating profile on the outside and/or for positioning the terminating profile directly adjacent at least partially. This means in particular that, viewed in the height direction of the door, the contact wall is to be dimensioned and understood as intended with regard to an overlap with the end profile provided in this height direction in the assembled final state. Areas of the base part and the end profile, which are therefore not arranged overlapping with the abutment wall in this height direction in the assembled final state of the end profile, are also not to be counted as part of the abutment wall in the context of the understanding. In addition, it is provided that the contact wall does not have to be directly contacted over the entire surface by the end profile in the installed state or the end profile does not have to rest directly on the outside of this contact wall over the entire surface. The contact wall is also provided so that in the final assembled state there can be a small spacing between the contact wall and the end profile, in particular at least in certain areas.

Viewed perpendicularly to the longitudinal axis, but viewed in the horizontal direction and therefore not in the height direction of the door, the contact wall has a front wall area, an adjoining central wall area and an adjoining rear wall area. In this depth direction, the front wall area, the middle wall area and the rear wall area are designed without interruptions in at least one height position in a horizontal section. This horizontal section is formed in a plane that is spanned by the depth direction and the width direction of the door. The horizontal section is formed at a level at which the contact wall is formed. It is therefore formed at an altitude in which, in the assembled end state, a section through the contact wall and also through the end profile that is then present there and overlaps with the contact wall is arranged.

With such a design of a contact wall, which is designed without interruption at such a point of a specific horizontal section, unwanted leakage points at which thermal insulation foam, which could escape at the interface between the closing profile and the contact wall from a gap in the door during the foaming process, can be avoided or at least significantly reduce it. This specific structuring of the installation wall with the front wall area, the central wall area, the rear wall area and its completely uninterrupted shape in this horizontal section makes it possible to better prevent such insulation foam from escaping at all points, especially in the specific front corner area. A wall labyrinth without interruptions in this horizontal section can thus be formed by such a construction of the contact wall. This makes it possible, in a particularly advantageous manner, that during the foaming process, if necessary, foam can get into the space between the contact wall and the end profile, but due to the uninterrupted structure and the possibly small distance between the end profile and the contact wall, a situation is created in which the foam does not escape to the outside can. Because the foam runs through this specific uninterrupted wall labyrinth, if it can get into this interface area at all, dead, so that it would already have hardened before it could exit the door to the outside at this interface area between the contact wall and the end profile. Due to this specific configuration of the installation wall, a coherent and uninterrupted wall section line is formed in this horizontal section. This is completely formed, viewed in a horizontal direction perpendicular to the longitudinal axis, from a front side to a rear side of the terminating profile. This uninterrupted wall section line thus extends from the front of the end profile to the back of this end profile without a gap. This also forms a contact wall, which in this regard is also arranged and configured to run in the same direction over the corresponding extension of the closing profile.

In particular, it is provided in one embodiment that such an uninterrupted configuration of the contact wall is not only formed at one level, but is realized over at least one continuous vertical section viewed in the vertical direction. This can have a height of at least 0.5 cm. In particular, this can be formed in a height section that can extend over a height of between 0.5 cm and 10 cm. In this regard, however, the height section can also be higher.

In one embodiment, the contact wall with the front wall area, the middle wall area and the rear wall area as well as the end profile are each designed without interruption in this horizontal section. Thus the end profile does not have any gaps in this overlapping area and in this horizontal section. This further improves the close-meshed specific wall labyrinth, which extends almost without interruption from the front to the back of the end profile.

In one exemplary embodiment, the contact wall with the front wall area, the middle wall area and the rear wall area as well as the end profile have the same shape over the entire length in this horizontal section. In particular, in this horizontal section, the contact wall and the terminating profile are arranged so as to run parallel or substantially parallel to one another over the entire length. This is another very advantageous embodiment. On the one hand, the mechanical stability of the interface between the end profile and the contact wall can be improved in this regard. In a particularly advantageous manner, however, an identical shape or essentially an identical shape is formed between these two separate components from the front to the rear. On the one hand, this improves at least the mutual contact between an inner side of the closing profile and an outer side of the contact wall, at least in certain areas. On the other hand, only a minimal clearance is formed at those areas where an abutment is not formed. Viewed in the plane of the horizontal section, this minimum distance can be less than 5 mm, in particular at all points. Such, at most minimal, spacing forms such a small gap that, in connection with the other specific feature already explained above, the dead running of any foam that may have penetrated occurs very quickly and the foam at this interface is prevented from spilling out to the outside.

In one exemplary embodiment, the contact wall with the front wall area, the central wall area and the rear wall area has a continuous multiple U shape in horizontal section. In particular, an embodiment with three U-like sections is formed here. In particular, a shape or shape progression is realized that is only formed by these three U-like sections. Such a specific shape of the contact wall promotes the advantages mentioned above to a particular extent. On the one hand, a corresponding stability is achieved as a result. On the other hand, a wall labyrinth is formed to a particular degree, which particularly efficiently prevents the foam from spilling outwards at this interface due to the uninterrupted design in the horizontal section with the particularly similar or identical shape of the end profile. The juxtaposition of these several U-shaped sections can be seen in the horizontal direction perpendicular to the longitudinal axis of the end strip, in particular in the depth direction of the door. Accordingly, it can be said that in the horizontal section in the direction from the front to the back of the end strip, this juxtaposition of the three U-like sections is formed. In particular, these are lined up directly next to one another. In this regard, a particularly specific meandering shape of this contact wall is formed. It extends particularly from the front to the back of the end profile in this individual shape.

In one embodiment, the three U-like sections are oriented alternately with their U-openings viewed in this horizontal section. This means that viewed in this horizontal direction perpendicularly to the longitudinal axis, a first U-shaped section is oriented with its U-opening towards one end of the end strip. In contrast, the further second U-like section that follows in the direction perpendicular to the longitudinal axis is around Rotated 180° or essentially 180° in this horizontal sectional plane. Its U-shaped opening thus faces the opposite other end of the end strip, viewed in the direction of its longitudinal axis. The third, U-like section following in the direction perpendicular to the longitudinal axis is again oriented in this horizontal sectional view like the first U-like section. The U-opening of this third U-like section is therefore again facing the end of the end strip, which is also facing the U-opening of the first U-like section.

In one embodiment, the center wall portion has a U-shaped section. On the one hand, this is directly adjoined by the front wall area, which forms or has a freely cantilevered U-leg of a further, connected U-like section. It is thus provided that a U-leg is both a component of the U-like section of the middle wall area and at the same time is also a U-like leg of the front wall area with its U-like section.

In a further exemplary embodiment, the central wall area has the U-shaped section, which is adjoined by the rear wall area, which forms a freely projecting U-leg of a further U-shaped section. In this regard, a U-leg of the middle wall area also forms a U-leg of the rear wall area at the same time.

In particular, a closed wall structure of the contact wall is formed by the front wall area and its U-like section at a front corner area of one end viewed in a direction perpendicular to the longitudinal axis of the closing profile in a horizontal section.

In particular, a specific wall labyrinth can thus be created in such corner regions between the contact wall and the end profile overlapping therewith in the height direction, which prevents the escape of foam in a particularly advantageous manner.

In one exemplary embodiment, the front wall area has the same first height when viewed in the height direction. This means that the entire front wall area is the same height in the direction of its longitudinal extension. In one embodiment, this first height is greater than the height of the rear wall area. This rear wall area has a second height. In one exemplary embodiment, this is of the same design over the entire length of the rear wall area. Such a configuration makes the front wall area higher than the rear wall area. In particular, this applies to the entire length of these mentioned areas. With such a stepped design of the contact wall, further improvements in terms of foam tightness can be achieved with regard to the individual positioning of the end profile and the respective critical interface areas between the end 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 cm and 6 cm. Due to these relatively large dimensions, relatively large overlapping heights can be achieved between the contact wall and the end profile in the vertical direction of the door. In addition to the shape mentioned above and the configuration of the abutment wall that is free of interruptions in the horizontal section from the front to the rear of the end strip, foam tightness can be achieved to a particular degree at this interface.

Preferably, the center wall area is stepped. In particular, it has exactly one discrete wall height step. In particular, this is a vertical step edge. The advantages mentioned above can also be positively supported by this specific geometry of the installation wall at this specific point.

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

In a further exemplary embodiment, it can be provided that the front wall area, the middle wall area and the rear wall area of the contact wall have the same height as viewed in the vertical direction of the door. This means that they each have the same height, viewed over their entire length, and in turn then also have this same height in comparison to one another. In this regard, the upper edge of the abutment wall has no wall height variation over these three areas.

In one embodiment, the abutment wall has a single U-shape in the horizontal section. This is advantageous when the contact wall does not have to be formed with multiple angles and the closing profile is not formed with multiple angles in this regard. A multiple angled shape of the end profile is provided when the end profile is a boundary wall for a recessed grip that is formed in this narrow side area of the door. If such a recessed grip is not provided on such an edge side of the door, a simple design of the end profile and thus also a simple design of the End strip possible, especially in the interface area with the end profile. Therefore, in the exemplary embodiment, the shape as a single U-shape for the contact wall is also sufficient in this horizontal section.

In one exemplary embodiment, the abutment wall has a horizontally running abutment wall strip that is designed without interruption over all wall areas. This is formed on a support wall of the terminating profile and protrudes outward beyond the outside of the support wall. It is therefore sufficient in such a configuration that only one such contact wall strip is provided as intended for possible application to the inside of the terminating profile. Viewed in the vertical direction, this contact wall strip is narrower 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. It thus also forms the upper end of the support wall in this respect.

A further aspect of the invention relates to a household refrigeration appliance with a door according to the aspect mentioned above or an advantageous exemplary embodiment thereof. The household refrigeration appliance can be, for example, a refrigerator or a freezer or a fridge-freezer combination appliance. The household refrigeration appliance is designed for storing and preserving food. The household refrigeration appliance has at least one storage space for food. The receiving space can be a refrigerator compartment or a freezer compartment.

The door has a metal wall, for example, as the outer wall. For example, this can be a sheet metal wall. In addition, the door has an inner wall. This can also be referred to as interior lining. The inner wall is usually made of plastic. Thermally insulating material, in particular insulating foam, is placed in an intermediate space between the outer wall and the inner wall. On the side, the door is bordered on the edge strip by the end profiles already mentioned. The door is delimited at the top and bottom by an end strip, which has also already been explained.

The directions “in the direction of width”, “in the direction of height”, “in the direction of depth”, “top”, “bottom”, “front”, “back”, “outside”, “inside” etc. for the door and the household refrigeration appliance relate to the state of a household refrigeration appliance set up for conventional use, with the door positioned in front for an observer and the back in the back.

In 7 an exemplary embodiment of a household refrigeration appliance 1 is shown in a perspective, simplified illustration. The household refrigeration appliance 1 can be, for example, a refrigerator or a freezer or a fridge-freezer combination appliance. The household refrigeration appliance 1 is designed for storing and preserving food. It has a housing 2 in which at least one receiving space 3 for the food is formed. A door 4 is pivotably arranged on the housing 2 so that the receiving space 3 can be closed from the front or from the front.

The door 4 is constructed in several parts.

In 8th an embodiment of a door 4 is shown in a perspective partial representation. The door 4 has an outer wall 5 . The outer wall 5 can be made of sheet metal. The door 4 also has an in 8th inner wall 6 which is not recognizable and is provided with a reference number. The inner wall 6 can also be referred to as the inner paneling of the door 4 . When the door 4 is closed, it faces the receiving space 3 . The outer wall 5 and the inner wall 6 are separate components from one another. A thermally insulating material 8, in particular insulating foam, is introduced into an intermediate space 7 between the outer wall 5 and the inner wall 6.

The door 4 also has narrow side edges, of which 8th only one is shown as a narrow margin 9. In the exemplary embodiment, this narrow side edge 9 is formed as a terminating profile 10 at the edge. As a result, the intermediate space 7 is limited at the side. In the exemplary embodiment shown, the end profile 10 is also a boundary wall 11 of a recessed grip 12. The recessed grip 12 is thus formed on this side edge 9 in this door or is integrated into it.

In the exemplary embodiment, the closing profile 10 is formed in one piece with the outer wall 5 . It is a component separate from the inner wall 6 . It is also possible that the end profile 10 and the outer wall 5 are separate components.

The end profile 10 can be designed in one piece. For example, it can be made of sheet metal.

The door 4 also has an end strip 13 . This is a lower end strip here. This can be seen in the height direction of the door 4 . The door 4 also has a further end strip 14 . This is a top finishing bar.

In 9 an exemplary embodiment of a lower end strip 13 is shown in a perspective view. This lower end strip 13 is designed in one piece. This can be made of plastic, for example. The end strip 13 is an elongate component.

The end strip 13 has a base part 15 . This is bar-shaped. The end strip 13 has a longitudinal axis A. This is oriented in the width direction (x-direction) of the door 4 . The end strip 13 has a first end 16 and an opposite end 17 viewed in the direction of the longitudinal axis A. In the depth direction (z-direction) and thus in the horizontal direction perpendicular to the longitudinal axis A, the end strip 13 has a front side 18 and a rear side 19 lying opposite in this respect.

A coupling structure 20 is formed at the end 16 . This has an abutment wall 21 . The abutment wall 21 extends upwards when viewed in the height direction. It is angled several times. It extends from the front 18 to the back 19 continuously. Viewed in the height direction, the contact wall 21 is that wall area which is intended to be arranged in an overlapping manner with the end profile 10 .

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

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

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

The abutment wall 21 is intended to be provided for at least some areas on the outside to place the end profile 10 on it. The abutment wall 21 has the front wall area 24 already explained. This front wall area 24 is a U-like section 29 here. This U-like section 29 has a U-leg 29a. This is the free cantilevered U-leg here. In this direction, perpendicular to the longitudinal axis A, it is the section of the contact wall 21 that lies furthest to the front. It faces the opposite end 17 with its freely cantilevered orientation. In addition, this U-like section 29 has a second U-leg 29b. This is at the same time also a U-leg 30a of the middle wall area 25. This middle wall area 25 is also designed as a U-like section 30 in the exemplary embodiment. This U-like section 30 has another U-leg 30b. Furthermore, a bottom leg 30c is formed, which completes this U-like area 30 here.

The rear wall area 26 is also designed as a U-shaped section 31 in the exemplary embodiment. It has a freely projecting U-leg 31a. Furthermore, it has another U-leg 31b. The U-leg 30b is also the U-leg 31b at the same time.

As can be seen in this multiple U-shape of the contact wall 21, the U-openings of the U-like area 29 and the U-like area 31 are oriented in the same direction, specifically towards the opposite end 17 of the end strip 13 . In contrast, the U-opening of the U-like section 30 lying in between in this respect faces away from the opposite end 17 . In addition, it can be seen that the U-leg 30a corresponds to the U-leg 29b. The U-leg 30b corresponds to the U-leg 31b. The freely cantilevered leg 31a of the U faces the opposite end 17 with its orientation. In addition, when designing in 10 it can also be seen that the contact wall 21 does not have the same height. In this regard, the front wall area 24 is designed with the same height, namely a first height h1, over its entire extent. In contrast, in the exemplary embodiment, the rear wall area 26 is designed with a second height h2. This is smaller than the first height h1. The heights h1 and h2 are measured from the roof wall 28. In the exemplary embodiment, this rear wall area 26 has the same height h2 over its entire extent. The middle wall area 25 with its U-like section 30 shown here has a varying height. In this regard, in the exemplary embodiment, the U-leg 30a and the bottom leg 30c adjoining it have the height h1. A height offset 32 is formed in the transition between the bottom leg 30c and the further U-leg 30b. This discrete step is a single step variation over the entire length of the abutment wall 21 . There is a jump in height from the height h1 to the lower height h2.

In addition, in 10 It can also be seen that towards the outside at this end 16 a configuration of a web 33 is realized which is spaced apart from the contact wall 21 . Viewed in the height direction, the web 33 is much lower than the contact wall 21, in particular also the smaller height h2. This web 33 is spaced apart from the contact wall 21 over its entire length. As a result, a slot 34 is formed between the outside of the contact wall 21 and the inside of the web 33 . A lower edge 35 of the terminating profile 10 dips into this slot 34 in the assembled end state.

It is provided that in a sectional plane, which is formed by a horizontal section, the abutment wall 21 is designed to be completely uninterrupted over its height, at least in regions. In the present exemplary embodiment, the contact wall 21 can be provided as a completely uninterrupted contact wall 21 in a horizontal section that extends through the xz plane at a height where the second height h2 is formed. In the height direction, the end profile 10 overlaps with the contact wall 21. This also applies in particular to the area in which the height h2 is formed. In the exemplary embodiment shown here, the contact wall 21 is designed specifically in order to enable an end profile 10 which has the recessed grip 12 integrated. In particular, the shape and thus the shape of the contact wall 21 is adapted to the shape of the terminating profile 10 , particularly in the area of the recessed grip 12 . In particular, a corresponding shaping of the closing profile 10 is realized over the entire extent of the contact wall 21 . Especially in the area where the horizontal section the contact wall 21 is designed without interruption over its entire length, the shape of the end profile 10, which can be seen in the section, is also designed in the same way.

As a result, an advantageous wall labyrinth is formed at this interface between the end profile 10 and the contact wall 21 .

In 11 is the representation according to 10 shown from a different perspective. As can be seen here, a continuous uninterrupted design of this wall 21 is also formed in a front corner region 36 of the wall 21 . This applies in particular to the height h2 of the contact wall 21. It can therefore be said in general that in a horizontal section, which is in the area between the lower end of the contact wall 21, which ends, for example, directly on the roof wall 28 and a maximum of up to a height h2 is sufficient, the contact wall 21 is completely uninterrupted.

In 12 10 is a perspective section through the arrangement according to FIG 10 shown when the end profile 10 is arranged in the final assembled state on the lower end strip 13. As can be seen here, this terminating profile 10 is introduced into the slot 34 in particular with the lower edge 35 . This identically formed course of shape between the contact wall 21 and the closing profile 10 over the entire length in this horizontal section according to FIG 12 can be seen. As in 12 can be seen in the perspective horizontal section, here the outer wall 5 lies directly on the outside of the front wall area 24, in particular the outside of the U-leg 29a. In one exemplary embodiment, however, it is also possible for a distance to be formed here.

Correspondingly, for example, a rear fold 37 of the terminating profile 10 can also rest directly on an outside of the contact wall 21, here on the outside of the U-leg 31a. However, it is also possible for the folded edge 37 to be arranged at a distance from the U-leg 31a. this is in 12 shown. In the exemplary embodiment shown here, a spaced arrangement is also formed between the end profile 10 and the contact wall 21 . In this respect, however, a respective distance is formed in the horizontal plane, which is less than 5 mm everywhere. The structure in this regard enables an arrangement labyrinth to run in the same shape between the contact wall 21 and the end profile 10.

It can be provided that the distance between the fold 37 and the U-leg 31 and/or a distance between the outer wall 5 and the U-leg 29a is much smaller than a distance between the remaining end profile 10 and the remaining contact wall 21 is formed.

In 12 a horizontal section is drawn for the sake of clarity and for recognizing the wall height h2, which is formed above the height h2 and in the area of the height h1. This is only with regard to the perspective for better recognition of the individual components. Because then it can also be seen here that with a horizontal section in the region of the height h2, this completely uninterrupted design of the contact wall 21 is realized over the entire length.

In 13 a further exemplary embodiment of an end strip is shown in a perspective view, which is also a lower end strip 13 here. In one exemplary embodiment, this end strip 13 is designed in one piece, in particular made of plastic. The bottom bar 13 according to 13 is part of doors 4 in particular that do not have a recessed grip 12 on the side edge.

Again, as in 13 at the end 17 can be seen, a contact wall 21 is formed. This is realized here as a contact wall strip 21a. Here, too, an uninterrupted configuration of this contact wall 21 is formed over its entire length in a horizontal section, which is formed in the height direction at the level of this contact wall strip 21a. In addition, corresponding wall areas 21b are formed here, which are realized flush with the contact wall strip 21a. These are oriented in the vertical direction. This is also in 14 , which shows an enlarged section of the illustration in 13 shows, represented. In 15 the end strip 13 is shown in a perspective view in the assembled state with an end profile 10 . Here, too, the corresponding lower edge 35, which cannot be seen, is inserted into a slot 34. The arrangement is shown here.

In 16 an embodiment of an upper end strip 14 is shown in a perspective representation. In terms of construction, this corresponds in the area of the coupling structure to the exemplary embodiment in 13 until 15 shown. A contact wall 21 with a contact wall strip 21a is thus realized here. In 17 an enlarged representation is shown in this regard. A support wall 38 is shown. The contact wall strip 21a is formed on this and protrudes outwards. The same applies to the wall area 21b.

In addition, in 18 a perspective view of the end strip 14 in mount tem state with a corresponding end profile 10 shown. In a horizontal section, which is formed at a level within the range of the height of the contact wall strip 21a, there is an uninterrupted contact wall 21 over its entire length in this horizontal section. Here, too, the abutment wall strip 21a is arranged in a height range and is provided as intended by forming an overlap in the height direction with this end profile 10 in the assembled state.
