INNER CONTAINER WITH SPECIFIC SHAPE OF A SUPPORT RIBBON, AND HOUSEHOLD REFRIGERATION APPLIANCE

Description

[0001] One aspect of the invention relates to an inner container for a household refrigeration appliance. The inner container has a side wall on which an elongated support rib for a support plate is integrated. The support rib extends along its longitudinal axis, which is measured in the depth direction of the inner container, over at least half of the depth of the side wall measured in this depth direction. The support rib has a top surface. With a first curve in cross-section perpendicular to the longitudinal axis, the top surface meets the side wall. With a second curve in this cross-section opposite it, in the width direction of the inner container, this top surface meets a bottom surface of the support rib. The bottom surface of this support rib meets the side wall at its lower end. With respect to an upper and a lower end, this is to be understood as being in the vertical direction of the inner container.Another aspect of the invention relates to a household refrigeration appliance with such an inner container.

[0003] US 4 914 341 A discloses a body of a refrigeration appliance with a separating element to form an upper freezing compartment and a lower cooling compartment, wherein the separating element is supported by inwardly directed ribs.

[0004] KR 1999 0019300 A discloses a structure for supporting shelves in a refrigeration appliance, comprising lower ribs on the shelf in which ribs a plurality of rollers for supporting the shelf are integrated.

[0005] Household refrigeration appliances are known to consist of an outer casing and an inner container located within it. The inner container is usually made of plastic, for example, by deep drawing. The inner container's walls define a storage space for food within the appliance. A space between the inner container and the outer casing is typically filled with thermally insulating material, such as insulating foam or vacuum insulation panels.

[0006] Support ribs are molded onto the vertical side walls of the inner container on opposite sides. A separate support plate, such as a shelf or similar item, can be placed on these.

[0007] In this context, a wide variety of support rib designs are known. They can be elongated or beam-like support ribs. Furthermore, locally confined, block-like elements, which can be shaped like a quarter moon, for example, are also known.

[0008] These support ribs typically have to meet several requirements. They must be designed to be mechanically stable, thus enabling them to securely support a support plate and any stored goods placed on it. Since they are formed in one piece from the same material as the side wall, particularly through deep drawing, the walls of the support rib must be designed to achieve this stability. They must not be too thin, as this would reduce their strength. Furthermore, a design that allows the cavity to be completely filled with thermally insulating material is also desirable, ensuring that the support rib, on its side facing the outer casing, is entirely filled with this insulating material.Furthermore, the inner container is designed with several support ribs at different heights along one side wall. This allows a support plate to be installed at different insertion levels within the container, or several separate support plates to be installed simultaneously at different heights. To facilitate easy removal of the support plate and easy placement of such a plate onto a support rib, an advantageous design is provided. This design ensures easy handling and prevents unwanted contact with a support rib located above it.

[0009] The object of the present invention is to create an inner container that is shaped in such a way that it has high stability on the one hand, and on the other hand allows for user-friendly handling for removing and attaching support plates.

[0010] This problem is solved by an inner container and a household refrigeration appliance according to claim 1.

[0011] One aspect of the invention relates to an inner container for a household refrigeration appliance. The inner container has a vertical side wall. At least one elongated support rib is integrated into this side wall and thus formed integrally with it. The support rib is designed, in particular, as a beam or elongated web. Its length is therefore greater than its width and height. In particular, its length is at least twice as long as its width and height. The support rib has a longitudinal axis that extends in the depth direction of the inner container. The support rib extends, in particular, over at least half of the depth of the side wall. The length of the support rib along this longitudinal axis is thus at least half of this side wall. The support rib has a top surface for placing the support plate upon it.The support plate, viewed in the width direction of the inner container and in a cross-section perpendicular to the longitudinal axis, terminates with a first curve against the side wall. With a second curve opposite this, also viewed in the width direction of the inner container and in cross-section, this upper surface of the support plate terminates with a lower surface of the support rib. In cross-section, this lower surface terminates at its lower end against the side wall. At its upper end, this lower surface terminates with this second curve.

[0012] Particularly in the cross-section of the support rib that is oriented perpendicular to the longitudinal axis, the support rib, in an advantageous embodiment, preferably has a vertical dimension ratio, measured in the height direction of the inner container, between a bottom vertical dimension and a top vertical dimension. This advantageous vertical dimension is measured between the values ​​3.5 and 4.5, particularly between 3.8 and 4.2. The bottom vertical dimension extends in this height direction between an upper end of the bottom surface and a lower end of the bottom surface. The top vertical dimension extends in this height direction between an upper end of the first curve and a lower end of the second curve. The bottom vertical dimension is thus a straight dimension measured in the height direction. Likewise, the top vertical dimension is a straight dimension measured in the height direction.

[0013] This cross-sectional geometry of the support rib achieves the aforementioned advantages. The support rib is mechanically stable and resilient, and can also be manufactured with relatively high precision. This rib geometry of the side wall can be precisely produced, particularly through thermoforming. This specific dimensioning of the clearly defined sections of this support rib in the cross-sectional view allows the aforementioned requirements to be met particularly advantageously, even in combination.

[0014] In particular, this cross-sectional shape of the support rib is formed at least at one point along its longitudinal axis. Preferably, this shape is formed at least at one point along the front half of the support rib's longitudinal axis. Specifically, this vertical dimension ratio is defined as extending over at least one-third, in particular at least half, and in particular at least 90 percent of the support rib's length when viewed along its longitudinal axis. This advantageously addresses the requirements for stability, formability, and user-friendly handling of a support plate for removal and placement on a support rib.Especially when several support ribs are formed at different heights, handling a support plate on a lower support rib can be very user-friendly and easy, since the upper support rib, particularly due to its geometry on the underside, also provides sufficient clearance in the vertical direction.

[0015] In one embodiment, the underside of the support rib is S-shaped at least at one point in a cross-section perpendicular to the longitudinal axis, when viewed along the longitudinal axis. This shape particularly supports the aspects mentioned above. High deformation stability, high load-bearing capacity, and especially a relatively large clearance at the bottom are achieved through this geometry, particularly on the underside.

[0016] Preferably, this S-shape has no straight section when viewed in this cross-section.

[0017] Preferably, this cross-sectional dimension of the underside is formed with an S-shape in a front half of the entire length of the support rib. In particular, such an S-shape is formed over at least 50 percent, in particular at least 60 percent, in particular at least 70 percent, in particular at least 80 percent of the front half of the length of the support rib.

[0018] In one embodiment, the vertical dimension of an upper S-shaped section is smaller than the vertical dimension of a lower S-shaped section. This also addresses the aspects of stability, easy formability with a uniform wall thickness of the support rib across the entire cross-sectional geometry, and sufficient clearance in the lateral direction, which is also correspondingly large in the vertical direction.

[0019] In particular, it is stipulated that the vertical dimension ratio between the S-sections, viewed along the longitudinal axis, extends over at least one-third, and especially at least half, of the support rib. This also advantageously supports the aspects mentioned above.

[0020] In particular, it is provided that, viewed in cross-section, the curvature of the upper S-section is greater than that of the lower S-section. The underside is additionally stabilized in this respect and can therefore exhibit a high load-bearing capacity. This allows for advantageous force transfer from this underside to the side wall. Specifically, it is provided that the curvature of the upper S-section, viewed in the depth direction of the inner container and thus along the longitudinal axis of the support rib, increases from front to back. This also applies to the lower S-section, either additionally or instead.

[0021] In an advantageous embodiment, these curvatures converge when viewed from front to back. In particular, these curvatures continuously increase in value from front to back, and especially terminate at the rear end of the support rib in a vertical straight line in cross-section. The underside thus exhibits a specific trough-like bulge in at least two directions. This is formed by the S-shape. This S-shape changes continuously when viewed from front to back, so that it is completely dissolved in a rear region of the support rib, and thus no S-shape is present in cross-section. Consequently, the support rib in its rear region, especially at its rear end, appears straight in cross-section over its entire height on the underside.

[0022] In this respect, it is therefore bulged inwards to the maximum extent possible into the receiving space of the inner container.

[0023] In one embodiment, the upper S-section, viewed in cross-section, is bulged away from the side wall. This results in a convex curvature. The lower S-section is bulged towards the side wall, thus forming a concave wall section. This design particularly fulfills the aforementioned advantages and effectively meets the requirements outlined above.

[0024] In particular, it is provided that in the area of ​​the support rib where the underside has an S-shape in cross-section, the curvature of an upper S-part of the S-shape, viewed along the longitudinal axis from front to back, decreases, in particular continuously. Additionally or instead, it can be provided that in the area of ​​the support rib where the underside has an S-shape in cross-section, the curvature of a lower S-part of the S-shape, viewed along the longitudinal axis from front to back, decreases, in particular continuously.

[0025] In one embodiment, it is provided that in the cross-section, in the area of ​​the support rib where the underside has an S-shape in cross-section, this S-shape widens from front to back when viewed along the longitudinal axis, and at a rear area of ​​the support rib, the S-shape in cross-section continuously transitions into a straight line, or a straight line is formed at the rear end of the cross-sectional shape.

[0026] In a further embodiment, the upper support surface tapers, particularly continuously, from a starting point in a front third, or more precisely a front quarter, of the support rib towards the rear, viewed along the longitudinal axis. This design ensures that the widest possible support surface is formed in the front area. When the support plate is initially inserted, it can thus be securely positioned at the front and then slid to the rear. Since the support plate also rests with a certain amount of play on the opposite support ribs on the opposite side walls in the lateral direction, this dimensioning of the upper support surface also prevents the support plate from undesirably falling off laterally.Because it is wider at the front, the support plate cannot shift so far laterally that it would fall off. Furthermore, this design ensures that maximum width is available in the rear section of the inner container, particularly near the back wall. This is advantageous because it provides maximum lateral space in this rear section for a component of the household refrigeration appliance's refrigerant circuit. Specifically, this allows an evaporator to be positioned with maximum width in this rear section of the inner container.

[0027] According to the invention, a recess for receiving a rear end of the support plate is integrated into the side wall and thus formed in one piece. Viewed in the depth direction, the recess extends directly rearward from the support rib. The recess has a roof wall. Viewed in the depth direction of the inner container, this roof wall, according to the invention, also extends above the upper surface of the support. Thus, an overlapping arrangement is formed between the roof wall and the upper surface of the support in the depth direction. This creates a section in the rear area of ​​the support rib that is bounded downwards by the upper surface of the support and upwards by the roof wall. This is advantageous in that the roof wall forms a stop for the applied support rib at the top.If the support plate were subjected to force from above at the front, causing it to tip upwards at the rear, a complete forward tilting of the support plate can be prevented. This is because the rear of the support plate would then abut the roof wall. This also means that the roof wall, viewed in the width direction of the inner container, extends beyond a certain point that prevents such excessive upward tilting of the support plate. In particular, the clear width, measured in the width direction, between two such opposing roof walls with support ribs applied to the side walls at the same height is smaller than this width dimension of the support plate.

[0028] In particular, it is intended that this roof wall extends at most over the rear half of the length of the support rib. It is also specifically intended that the roof wall tapers from back to front when viewed from rear to front. Thus, when viewed along the longitudinal axis in the width direction of the inner container, the roof wall widens from front to rear.

[0029] In one embodiment, the first curve, viewed in cross-section, may have a radius approximately between 2 mm and 4 mm, particularly between 2.5 mm and 3.5 mm. It may be provided that this first curve does not have a constant radius over its entire length, but rather a changing radius, and that this radius value is present at at least one point. The second curve may advantageously have a radius between 2.5 mm and 4.5 mm, particularly between 3 mm and 4 mm, in cross-section. Here too, it may be provided that this first curve, viewed over its entire length, does not have a constant radius, but rather a changing radius, and that this radius value is present at at least one point.

[0030] In an advantageous embodiment, the radius of the upper S-section, viewed in cross-section, is between 7.5 mm and 15.5 mm, particularly between 8 mm and 15 mm. Here too, it is possible for the radius to vary along the entire length of this upper S-section and for this radius value to be present at at least one point. For a lower S-section, a radius between 19 mm and 31 mm, particularly between 20 mm and 30 mm, can be provided in cross-section. Here too, it is particularly possible for the radius to vary along the entire length of this lower S-section and for this radius value to be present at at least one point.

[0031] In one embodiment, a support rib tapers along its longitudinal axis with respect to its upper bearing surface. Starting from a point on the upper bearing surface, which is particularly the point furthest inwards in the width direction and furthest from the side wall, a continuous taper extends backwards in the depth direction. However, the taper does not extend all the way to the side wall. Thus, at the rear end, the upper bearing surface has a width greater than zero. From this point forwards, the upper bearing surface also tapers, specifically to a width of zero. The starting point is therefore the point furthest from the side wall in the width direction.In particular, a reduction in width of at least 10 percent, in particular at least 20 percent, in particular at least 30 percent, in particular a maximum of 50 percent of the width is formed at the starting point at the rear end 17 of the support rib 13.

[0032] A further width b1 of the support rib is measured at the point where the support rib exhibits its maximum contour in cross-section. This is defined as the maximum of the waveform formed in the cross-section of the support rib. This maximum contour is present at the same height along the entire length of the support rib.

[0033] In particular, at this starting point, the width-to-height ratio of the support rib, and thus the ratio b1 / (h1 + h2), is between 0.4 and 0.6, specifically between 0.45 and 0.55. This width b1 is measured relative to the first curve on the outside of the first curve. However, it can also be measured on the inside, resulting in the width b as mentioned above. The difference between the width b and the width b1 is therefore only the wall thickness. Standard wall thicknesses, as used in deep drawing, are applied for this purpose.

[0034] Preferably, the width b1 changes continuously from the starting point towards the rear. At the rear end of the support rib, this width b1 is not zero. In particular, the width at this rear end is between 25% and 40%, and more specifically between 30% and 35%, less than the width b1 at the starting point. In particular, the height h1 + h2 of the support rib is constant over at least 80%, and more specifically at least 90%, of its length. In particular, the height h1 + h2 remains constant from the starting point to the rear end. In particular, the width-to-height ratio can thus be determined at various positions along the length of the support rib.

[0035] At the front end of the support rib, the contour maximum ends directly at the side wall, so that the width b is zero at the front, or rather the width b1 only corresponds to the wall thickness.

[0036] Another aspect of the invention relates to a household refrigeration appliance with a housing. This housing, in particular, comprises an outer housing and a separate inner container. The inner container is designed according to the aspect mentioned above or an advantageous embodiment thereof. In particular, the inner container is housed within the outer housing. The inner container, with its walls, defines a receiving space for food.

[0037] In particular, the design enables a geometry for a support rib that addresses a wide range of aspects, both individually and collectively. The very smooth form transitions result in less internal stress during the molding and manufacturing process. This also helps to prevent stress cracks caused by temperature changes. These very smooth and gradual shape changes in the support rib also facilitate simple manufacturing. Despite this, the walls can be produced with a relatively uniform thickness. In particular, compared to conventional geometries and shapes of support ribs, this allows for thinner walls while still achieving at least the same level of stability.

[0038] Further independent aspects arise from the individual embodiments in the examples mentioned above, which do not necessarily have the features, in particular not necessarily the characterizing features of the first independent aspect mentioned above, especially of claim 1.

[0039] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction", etc. indicate the positions and orientations given when the inner container or the device is used and arranged as intended.

[0040] Further features of the invention are evident from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments of the invention are also to be considered as encompassed and disclosed that are not explicitly shown and explained in the figures, but which can be derived and generated from the explained embodiments by separate combinations of features. Embodiments and combinations of features are also to be considered disclosed that do not exhibit all the features of an originally formulated independent claim.

[0041] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a perspective view of an embodiment of a household appliance according to the invention with an embodiment of an inner container according to the invention; Fig. 2 a partial perspective view of an embodiment of an inner container; Fig. 3 a side view of a partial area of ​​a side wall of the inner container according to Fig. 2 Fig. 4 a perspective view of a section of a Fig. 3 opposite side wall of the inner container; Fig. 5 a perspective sectional view of a support rib as it appears in the side wall according to Fig. 4 Included is; Fig. 6 a front view of the sectional representation according to Fig. 5 ; and Fig. 7 a top view of a support rib as it appears in the side wall according to Fig. 3 is included.

[0042] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0043] In Fig. 1 Figure 1 shows a schematic representation of a household refrigeration appliance 1. The household refrigeration appliance 1 is designed for storing and preserving food. The household refrigeration appliance 1 can be a refrigerator, a freezer, or a refrigerator-freezer combination.

[0044] The household refrigeration appliance 1 has a housing 2. This housing 2 has an outer housing 3. Furthermore, this housing 2 also has a separate inner container 4. The inner container 4 is enclosed within the outer housing 3. A thermally insulating material 5 is inserted in a space between the outer housing 3 and the inner container 4. The inner container 4 has a bottom wall 6, a first vertical side wall 7, a second vertical side wall 8 opposite it, a top wall 9, and a rear wall 10. The front loading opening of the inner container 4 can be closed by a door 11 of the household refrigeration appliance 1.

[0045] The walls 6 to 10 of the inner container 4 define a receiving space 12 for food.

[0046] The inner container 4 is preferably manufactured in one piece. It is made of plastic, in particular by deep drawing.

[0047] In Fig. 2 A perspective view shows a section of the inner container 4. As can be seen, various support ribs are formed on the side wall 8 at different heights in the vertical (x-direction). For clarity, two support ribs are labeled 13 and 14. Corresponding support ribs are formed in one piece on the opposite vertical side wall 7. Again, for clarity, only two such support ribs are labeled 15 and 16.

[0048] The support ribs form a paired support device for a support plate (not shown). The support plate is a separate component from the inner container 4. It can be a shelf, a partition, or another plate-like cover. The support ribs 13 and 14, as well as 15 and 16, are integrally manufactured with the inner container 4.

[0049] The side wall 8 has a depth t1 measured in the depth direction (z-direction). A support rib 13, as shown in the side view in Fig. 3 The section 8, which represents a partial segment of the side wall, has a longitudinal axis A. This longitudinal axis A extends in the depth direction. The length l1 of this support rib 13, measured along this longitudinal axis A, is greater than half the depth t1. As can be seen, the support rib 13 is formed as an elongated rail or as a beam-like support. The other support ribs 14, 15, and 16 are formed accordingly.

[0050] As can be seen, a recess 18 adjoins this support rib 13 directly in the depth direction, specifically at a rear end 17 of the support rib 13. This recess 18 is designed to receive a rear end of a support plate. As can be seen, in the height direction (y-direction), this receiving area or recess 18 extends further downwards than a support surface 19 of the support rib 13. This ensures that the rear end or a coupling element of the support plate is securely mounted in the inserted end position, preventing it from being pulled out.

[0051] The niche 18 is bounded below, to the rear, and above. It has a roof wall 20. As can be seen, this roof wall 20 extends in this depth direction, overlapping the upper surface 19 of the support rib 13. In particular, this roof wall 20 extends above the upper surface 19 over the length of the rear third of the support rib 13, and at most over the length of the rear half of the support rib 13.

[0052] This roof wall 20 is also designed in the width direction, so that a guide channel is formed by this roof wall 20 and the upper surface of the support 19. Furthermore, the roof wall 20 also forms a tilt protection element for the support plate. It can therefore not tip forward unintentionally.

[0053] In particular, it is provided that the dimensions of the roof wall 20 change in the width direction (x-direction) from its front end 20a to its rear end 20b, and in particular that they increase towards the rear end 20b. Specifically, a continuous increase is designed in this respect.

[0054] In Fig. 3 and the Fig. 4 and 5The shape of the support ribs is also partially indicated with dashed lines. This is not only intended to show where the geometry of the support rib transitions seamlessly into the respective side wall. The dashed lines represent the geometric boundary of the support rib. The individual sections of the support rib itself also blend seamlessly into one another. This creates particularly smooth and edge-free transitions. Dashed lines shown within the support rib itself serve as guidelines for understanding the contour, especially on the underside of the support rib.

[0055] In Fig. 4 The perspective view shows the section of side wall 7, including the support ribs 15 and 16. Support rib 15 has a front end 21 and a rear end 22. For information on the design of a niche with a roof wall, please refer to the explanations regarding... Fig. 3 be referred.

[0056] As can be seen, a support rib has an individual three-dimensional shape. In particular, this shape of a support rib is similar to half of a ship's hull, with this half being oriented to a vertical plane that represents the ship's longitudinal axis. In this respect, the front end 21 can be seen in the form of the bow of such a ship's hull.

[0057] In this context, it can also be seen that the support rib 15 forms a specific shape in space on the underside 23. In this context, according to the perspective section view in Fig. 5 The support rib 15 is considered at the location of the section plane VV. The support rib 15 terminates at an upper end 24a (viewed vertically) at the side wall 7, in particular without a step. In this context, a first curve 25 is formed at this upper end 24a. The first curve 25 is part of the upper support surface 19. This upper support surface 19 has a flat area 26 extending from a lower end 24b of this first curve 25. This area extends essentially perpendicular to the side wall 7. Adjoining this flat area 26 is a second curve 27, which is part of the upper support surface 19. The second curve 27 connects directly to the area 26 at an upper end 28a. Viewed vertically, a lower end 28b is formed, which limits the upper support surface 19. The lower end 28b is also the lower end of the second rounding 27.Directly adjacent to this upper surface 19 of the support, the underside 23 of the support rib 15 is formed. The underside 23 connects directly to the lower end 28b at its upper end 29. A lower end 30 of the underside 23, in the vertical direction, is located in . Fig. 5 also shown.

[0058] In Fig. 6 The support rib 15 is shown in section VV. As can be seen in the exemplary embodiment, the cross-section is formed in a longitudinal half of the support rib 15 that is forward in the depth direction. In particular, the underside 23 is designed to be S-shaped. In this exemplary embodiment, this S-shape has no straight section. Specifically, this S-shape has an upper S-part 31. This extends from the upper end 29 to an intermediate point 32. The upper S-part 31 ends at this intermediate point 32. A lower S-part 33 of the S-shape extends from this intermediate point 32 to the lower end 30. As can be seen, the S-parts 31 and 33 have different curvatures. The upper S-part 31 is bulged away from the side wall 7 and thus towards the receiving space 12. The curvature of the lower S-part 33 is in the opposite direction. The bulge is therefore designed to face side wall 7.In particular, the lower S-part 33 is concavely curved and the upper S-part 31 is convexly curved.

[0059] In particular, a stepless transition is formed at the intermediate point 32 between the S-parts 31 and 33. In particular, a stepless transition is formed between the underside 23 and the side wall 7 at the lower end 30. In particular, a stepless transition is formed at all points along the contour of a support rib where the aforementioned sub-elements merge into one another.

[0060] As in Fig. 6 As can be seen, the upper support surface 19 has a vertical dimension h1. This dimension is measured in the vertical direction and lies between the upper end 24a and the lower end 28b. The lower surface 23 has a vertical dimension h2. This dimension lies between the upper end 29 and the lower end 30. As can be seen, the vertical dimension h1 is smaller than the vertical dimension h2. In particular, the ratio of the vertical dimension h2 to the vertical dimension h1 is between 3.5 and 4.5, and more specifically between 3.8 and 4.2. Preferably, this ratio is formed over at least 50 percent, more specifically at least 60 percent, more specifically at least 70 percent, more specifically at least 80 percent, and more specifically at least 90 percent of the length of the support rib 15 measured in the direction of the longitudinal axis A.

[0061] In particular, this vertical dimension ratio between the bottom vertical dimension h2 and the top vertical dimension h1 is constant over the length of the support rib 15.

[0062] Furthermore, it can also be seen that a vertical dimension h4 of the upper S-part 31 is smaller than a corresponding vertical dimension h3 of the lower S-part 33. In particular, the vertical dimension h3 of the lower S-part 33 is at least twice as large as the vertical dimension h4 of the upper S-part 31. Here, these vertical dimensions h3, h4 are measured in the vertical direction and are measured on the one hand between the upper end 29 and the intermediate point 32, and on the other hand between the intermediate point 32 and the lower end 30.

[0063] Preferably, the support rib 15 has such an S-shape of the underside 33, viewed in cross-section, over at least 50 percent of its length, in particular at least 60 percent of its length, in particular at least 70 percent of its length, along its longitudinal axis A.

[0064] This is also in Fig. 3 and Fig. 4 to recognize.

[0065] Furthermore, especially in Fig. 4 and Fig. 5 It can be seen that the S-shape changes continuously in cross-section when viewed along the longitudinal axis A. In particular, it is intended that this S-shape widens when viewed from front to back. This means that, viewed from front to back, the curvature of the S-shape in the upper part 31 decreases or diminishes, in particular diminishes continuously. A similar curvature is also intended for the lower part 33 of the S. As further described in Fig. 4 and Fig. 3 As can be seen, the support rib 15 at its rear end 22 no longer has an S-shape in the cross-section of the underside 23, but rather a straight line 34 in this cross-section. This means that from front to back, the underside 23 continuously transitions from an S-shape to a vertical straight line 34. The underside vertical dimension h2 also applies to the straight line 34. This means that the underside 23 curves most strongly towards the side wall 7 at the front, and this curve towards the side wall 7 decreases towards the rear, so that at the rear end 22 only the straight line 34 is formed in the cross-section. For a better understanding of the shape in this respect, see in Fig. 6 This straight line 34 is drawn as a dashed vertical line, serving as a guideline.

[0066] In one embodiment, it is provided as shown in the top view according to Fig. 7 It can be seen that a support rib tapers along its longitudinal axis with respect to its upper bearing surface 19. In this context, a continuous taper of the upper bearing surface 19 is formed extending backwards from a starting point 35 in the depth direction. A further taper of this upper bearing surface 19 is also formed forwards from this starting point 35. The starting point 35 is thus the point furthest away from the side wall 8 in the width direction. Specifically, a reduction in width of at least 10 percent, in particular at least 20 percent, in particular at least 30 percent, and in particular at most 50 percent of the width b is formed at the starting point 35 at the rear end 17 of the support rib 13. The width b is measured on the inside of the first curve 24.

[0067] In particular, the cut in Fig. 6 at the starting point 35, such that this point lies in the cutting plane. In the lateral direction x, the upper surface of the support 19 has its greatest width at this point of the starting point 35.

[0068] In Fig. 6 The width b1 of the support rib 15 is also shown. This width b1 is measured at the point where the support rib 15 exhibits its contour maximum. It is defined as the maximum of the wave-like shape formed in the cross-section of the support rib 15. This contour maximum is present at the same height along the entire length of the support rib 15. In particular, this is at the location of the lower end 28b in the vertical direction.

[0069] In particular, in Fig. 6 The contour and thus the cross-sectional geometry at this starting point 35 is shown. In particular, the width-to-height ratio of the support rib 15, and thus the ratio b1 / (h1 + h2), is between 0.4 and 0.6, specifically between 0.45 and 0.55. This width b1 is dimensioned relative to the first radius 24 on the outside of the first radius 24. However, it can also be dimensioned on the inside, resulting in the width b. The difference between the width b and the width b1 is therefore only the wall thickness. Standard wall thicknesses, as used in deep drawing, are used for this purpose.

[0070] Preferably, the width b1 changes continuously from the starting point 35 towards the rear. At the rear end 17, this width b1 is not zero. In particular, the width at this rear end 17 is between 25% and 40%, and especially between 30% and 35%, less than the width b1 at the starting point 35. In particular, the height h1 + h2 of the support rib 15 is constant over at least 80%, and especially at least 90% of its length. In particular, the height h1 + h2 remains constant from the starting point 35 to the rear end 17. In particular, the width-to-height ratio can thus also be determined at the various length positions of the support rib 15.

[0071] At the front end of the support rib 15, the contour maximum ends directly at the side wall 7, so that the width b is zero at the front, or rather the width b1 corresponds only to the wall thickness. Bezugszeichenliste
