Abstract

The tub has a top peripheral edge (3). In order to achieve improved utilisation of the standing surface with visually advantageous arrangements, seen in the projection of the standing surface (8) of the tub (21), the outside (7) of the edge (3) has on the front side (9) at least one set-back portion (11, 12) which deviates from a rectangle (R) surrounding the tub and extends over the entire height of the tub, due to which set-back portion the width (B1) of the tub is reduced in this region by at least 10%, preferably by at least 20%, in relation to the width of the rectangle (R). <IMAGE>

Description

The invention relates to a bathtub for body cleaning purposes such as a bathtub and shower tray with a front and an upper edge with outer sides, which - seen in the projection onto the installation surface of the bathtub - lie in a rectangle (R) circumscribing the projection of the bathtub, the linear projection line of the rear outer side of the tub opposite the front coincides with the rear side of the rectangle (R) and the projection lines of the two lateral outer sides of the tub adjoin the rear right side at least in their rear rectilinear area and coincide with the two lateral rectangular sides.

Tubs with these geometrical relationships are, for example, bathtubs with a head end and a foot end, the projection lines from the head and foot end lying at least partially on the narrow sides of the rectangle (R) and extending in a straight line and at right angles to the rear long side of the rectangle and where the projection line connecting the projection lines from the head and foot ends of the rear rectilinear outside lies on the same long side of the rectangle.

From DE-U-1 815 524 a hexagonal bath is known, the plane of symmetry for obtaining a large length of the cavity lies in the diagonal of a square that circumscribes the hexagon. As a result, the square must have a relatively large side length of, for example, 110 cm. The parallel alignment of the plane of symmetry to a bathroom wall is forbidden because the inclined surfaces of the tub with the wall would include useless and difficult to clean acute angles and because the corners lying in the plane of symmetry mentioned would make it impossible to place other bathroom facilities next to one another. The known tub is therefore only intended and suitable for installation in a corner of the room. However, this gives away a footprint corresponding to the triangular gusset behind the tub.

From DE-U-8 335 230 an octagonal bathtub with a circumscribing rectangle with the extraordinary size of 184 cm × 124 cm is known, which cannot be placed directly against a wall with a reasonable orientation. Otherwise dead corners would also arise here or valuable floor space would be given away. The bathtub is therefore only intended and suitable for free installation within appropriately large bathrooms. It cannot be structurally combined with other bathroom facilities such as shower cubicles.

From DE-A-3 224 678 a bathtub is known in which the parallel orientation of the longitudinal axis of the cavity to a wall corresponds to the usual arrangement. The basic body of this tub can be roughly outlined as a rectangle. The front of the tub, however, is drawn forward to about half its length in the lower region by a projection designed as a trough-shaped step into the bathroom, and the the other half of the front tub edge is thickened or arranged to such an extent that the front edge of the step and the advanced part of the tub edge - seen in the projection onto the installation surface of the tub - form a straight line. This significantly increases the footprint of the tub, particularly when the step is extended beyond the length of the tub and also serves as a foot washing area and step for an integrated shower cubicle. Such a tub or tub combination cannot be used in small and very small bathrooms if, for example, the distance from the wall in front of which the tub is installed to a door is smaller than the tub width, as seen in the projection onto the installation surface. Difficulties also arise when there are other items of furniture in front of the opposite wall, such as a toilet, bidet, wash basin, vanity unit or cupboard, and if there is still a passage in between.

Rather, the invention is based on one of the usual troughs with a rectangular outline, in which the rear edge and the two side edges of the edge, as seen in the projection, lie on the sides of a rectangle and in which there are no other projections, etc., against the doors to the stop or that could become an obstacle in narrow passages.

In standard bathtubs, the outer edges correspond to a rectangle with long sides of 160 to 180 cm in length and narrow sides of 70 to 80 cm in width. Together with an associated base element, which often consists of hard foam and with tiles or other ceramic decorative panels can be occupied, such bathtubs have the shape of a cuboid with a floor plan, the dimensions of which are within the ranges mentioned. The installation of such bathtubs becomes more difficult, the smaller the layout of the bathroom. If the distance of a door edge is smaller than the relevant width dimension of the bath tub, it is forbidden to install the bath tub near the door. This is precisely the reason why additional space is wasted, and the niches that are created cannot usually be filled with other furnishings.

Bathroom facilities with the conventional standard baths therefore suffer from the considerable lack of an unsightly appearance and an insufficient use of space. The bathroom arrangements that are regularly found at trade fairs and exhibitions usually only have their practical and aesthetic effect because an excessively large exhibition area is available, which generally does not correspond to the available floor plans in modern residential buildings. One is therefore usually forced to accept unsightly and technically less than perfect "compromises".

In the past, attempts were also made to solve the space problem by means of so-called hip baths. Although these take up a smaller footprint, they necessarily shift the volume upwards, so that the unsightly appearance is further increased. For older people, who mostly have apartments with smaller bathrooms, there is also the problem of difficult entry or exit, so that seated bathtubs have not become widespread in any case.

On the other hand, tubs with the geometric relationships described above are also shower trays with an edge, with a rear wall, two side walls and a front side, the edge having an outside that determines the position of the walls and the front side and the projection lines of the outside in the area of the rear wall and at least lie in the rear area of the side walls on the corresponding sides of the rectangle (R).

The standard edges of the standard shower trays generally correspond to a square with an edge length of 70 to 85 cm. Very much smaller shower trays are hardly possible anymore, because then a shower cubicle placed on the shower tray no longer provides enough space for body cleaning. Together with an associated base element, which often consists of hard foam and with Tiles or other ceramic decorative panels can be covered, such shower trays have the shape of a cuboid with a floor plan, the dimensions of which correspond to the edge lengths mentioned.

The installation of such shower trays becomes more difficult the smaller the floor plan of the bathroom. If the distance of a door edge from the immediately adjacent corner of the bathroom is smaller than the relevant edge length of the tub, the installation of the shower tub near the door is prohibited. This is precisely the reason why additional space is wasted, and the niches that are created cannot usually be filled with other furnishings.

Bathroom facilities with the conventional shower trays therefore suffer from the considerable lack of an unsightly appearance and an insufficient use of space. The bathroom arrangements that are regularly found at trade fairs and exhibitions usually only have their practical and aesthetic effect because an excessively large exhibition area is available, which generally does not correspond to the available floor plans in modern residential buildings. One is therefore usually forced to accept unsightly and technically less than perfect "compromises".

Frequently, therefore, the installation of a separate shower or shower tray is dispensed with and a shower is installed above the bathtub, or the installation of a bathtub is dispensed with, so that the use of medical baths becomes impossible.

The invention is therefore based on the object of specifying a trough shape of the type described at the outset, which allows better use of the available space with optically more advantageous arrangements.

The problem is solved in the case of the tub shape specified at the outset in accordance with the invention in that the projection line of the outside on the front side has at least one recess at least one end opening into the associated side rectangle side with respect to said rectangle (R) and at least partially approximately parallel to the rear rectangle side through which the width of the tub is reduced in the entire height of the tub by at least 10% compared to the width of the rectangle.

In the bathtub described at the outset, the tub is designed in a particularly advantageous manner so that the part of the outside of the tub which is furthest forward in the projection onto the installation surface has the recess in the area of the foot end relative to said rectangle (R).

Such a spatial shape of the bathtub makes it possible to set it up on walls where the distance of the immediately adjacent door edge from the corner of the room is significantly smaller than the maximum width of the bathtub. It will be shown that this distance can correspond to at least about half the maximum width of the tub. The better use of otherwise unavailable corners of the room frees up floor space elsewhere that can be used to set up additional bathroom facilities, such as a shower cubicle. The associated subdivision of the front of the bathtub also enables a visually appealing design of the entire bathroom arrangement to be achieved. In particular, this makes small rooms appear larger, and there is also more freedom of movement around the bathtub. Since the recess is predominantly or exclusively provided in the area of the foot end or in the area of the legs, bathing comfort is in no way reduced, since the bathtub in the area of the pelvis and upper body retains a width which is not or only slightly reduced. The reduced water volume in the leg area also results in a corresponding saving in water and heating energy.

It is particularly advantageous if the outside of the edge forms a polygon, of which a central edge runs parallel to the long sides of the rectangle in the area of the recess at the foot end, and if this edge in the direction of the head end through a front, oblique edge connected to the front long side of the rectangle and if the same middle edge is towards the one at the foot end Narrow side of the rectangle is connected to it by a rear, also obliquely running edge. Such a spatial shape is shown in the top view in FIG. 1, to which express reference is made here. However, the figure also represents a mirror-symmetrical top view of the bathtub.

If the hinge axis of the door is arranged in the area of the extension of the central edge running parallel to the long sides of the rectangle, the door can be pivoted completely into the area of the recess, provided the length L of the recess corresponds to the width of the door leaf. If the distance between the hinge axis and the corner of the room is even smaller, the inclined edge that leads to the narrow side of the rectangle at the foot end allows at least a very extensive opening of the door leaf.

An advantageous further development of the subject matter of the invention is characterized in that the outside of the rim, as seen in the projection onto the installation surface of the tub, on the front in the area of the head end deviates from the rectangle (R) that outlines the tub, at least partially parallel to the long sides extending recess, through which the width of the trough in the area of the head end is reduced by at least 10%, preferably by at least 20%, compared to the width of the rectangle (R) is. Although there is generally no door at the point of the recess at the head end (bathrooms are rarely set up for passage), better accessibility can be achieved here, which is particularly advantageous if there are further bathroom fittings and / or there is a window. Above all, however, a shower tray can be directly connected at this point, which will be discussed in more detail below.

Such a bathtub is characterized in a particularly advantageous manner by a base element with vertical outer surfaces which are essentially congruent in the projection with the outer edge of the tub rim.

The solution of the task is carried out according to the invention in the shower tray mentioned above in that the outside of the edge, seen in the projection onto the installation surface of the tray, has two recesses in the front area deviating from the rectangle (R) outlining the tray, through which the width (B) of the trough in the region of the side walls is reduced by at least 10%, preferably by at least 20%, compared to the width of the rectangle (R).

Such a spatial shape of the shower tray makes it possible to set it up on walls where the distance of the immediately adjacent door edge from the corner of the room is significantly smaller than the maximum width the tub in the middle. The more general concept of the rectangle also includes the more specific concept of the square. The better use of otherwise unavailable corners of the room frees up space elsewhere that can be used for the installation of further bathroom facilities, such as a bathtub.

The associated subdivision of the front of the shower tray also allows a more visually appealing design of the entire bathroom arrangement. In particular, this makes small rooms appear larger, and there is also more freedom of movement in the area surrounding the shower tray or shower cubicle. Since the recesses are provided only in the area of the side walls, the shower comfort is not reduced in any way, since the shower tray in the front area - roughly speaking - approximates the circular shape, so that the required freedom of movement is also given with an attached shower cubicle.

It is particularly advantageous if the outside of the edge as seen in the projection onto the installation surface forms a polygon, of which a rear edge runs parallel to the front of the rectangle (R) in the area of the recesses, and if these edges on the one hand into the open on both sides of the rectangle (R) and on the other hand are each connected to the front of the rectangle (R) by a front, oblique edge.

The terms "front", "side walls" and "rear wall" refer to the line of sight that a viewer has when he stands directly in front of the shower tray, which can also be referred to as the "entry side".

A particularly advantageous embodiment of the shower tray is characterized in that the polygon has eight corners, four corners of which lie at the corner points of a second smaller rectangle which has the two rear corners in common with the first rectangle, that two further corners lie on a straight line , which connects the front corners of the second rectangle to one another, that two further corners lie in the front edge of the rectangle and that the position of two corners is mirror-symmetrical with respect to an axis of symmetry of the rectangle perpendicular to the rear wall. Such a spatial shape is shown in the top view in FIG. 5, to which express reference is made here.

It is easy to see from FIG. 5 that a door that is either on the left or right can be at least partially pivoted into the immediately adjacent recess if, for example, the hinge axis of the door lies in the area T.

It is in the course of an again advantageous embodiment of the shower tray if the side walls and the rear wall of the shower tray have a greater height than the front wall thereof.

This creates an entry opening in the area of the front wall, while the side walls have a height that corresponds to the standard height of a bathtub. If their directly adjacent end face corresponds in size to the size of the side wall, the shower tray can be visually and / or structurally combined with the bathtub so that it forms a unit, a so-called block, which is optically loosened by the polygonal structure.

Such a shower tray is characterized in a particularly advantageous manner by a base element with vertical outer surfaces which are essentially congruent in the projection with the outer edge of the tub edge.

A shower tray of the form described above is characterized in a particularly advantageous manner by a cabin structure made of transparent or translucent elements, of which two side elements are arranged above the side walls and two front elements serving as doors above the front wall of the shower tray, the projections of the elements being based on the footprint of the shower tray is within the projection of the edge.

The elements in question can be produced by bending corresponding glass or plastic plates at an angle. They are used in a particularly preferred manner frameless, which both improves cleanliness and promotes the visual appearance.

The expression "polygon" in all cases includes a more or less strong rounding of the outer edge of the edge at the "corners". Largely flat surfaces of the base element between the "corners", however, favor cladding with tiles or other ceramic decorative panels, such as marble, as well as non-ceramic decorative panels. When using tiles, the edge length is appropriately matched to the standardized edge lengths of tiles. It is also possible to cover the edge of the tub with cutouts from marble slabs, which gives it a particularly appealing look.

The material for the tubs itself is sheet steel or a corresponding cast material. Acrylic glass can also be used to manufacture such tubs. However, because of the somewhat more complicated spatial shape of such tubs, polyester resin with and without glass fiber reinforcement is preferably used.

Further advantageous embodiments of the subject matter of the invention emerge from the remaining subclaims.

An embodiment of the subject matter of the invention is explained in more detail below with reference to FIGS. 1 to 11.

1 has a head end 1 and a foot end 2, an upper circumferential edge 3 which can be placed on a base element, and also a base 5 provided with a drain opening 4, the edge 3 and the base 4 being connected to one another by side walls 6, whose generators run at a more or less acute angle to the vertical, as can also be seen from FIGS. 2 to 4.

The edge 3 has an all-round outer side 7, which represents a polygon in the projection onto the installation surface 8. The outside 7 is outlined by a rectangle R, which coincides with the outside 7, with the exception of the recesses explained in more detail below.

The tub has a front 9 and a rear 10, which usually abuts a wall. In the area of the foot end 2, the tub has a recess 11 opposite the rectangle R, which is delimited by the edges 12, 13 and 14, which form a polygonal line.

By the recess 11, the width B₁ of the tub in the area of the foot end 2 is reduced to about 55 to 60 cm. The length L of the recess 11 is approximately 50 to 55 cm with a total length of the bathtub of approximately 165 cm.

It can be seen that in the area of the recess 11 at the foot end 2, the central edge 13 runs parallel to the long sides of the rectangle R. This edge is connected in the direction of the head end 1 by the front, oblique edge 14 with the front long side of the rectangle R. Furthermore, the same middle edge 13 is connected in the direction of the narrow side of the rectangle R lying at the foot end 2 to the latter by the rear edge 12, which also runs obliquely. In the illustrated embodiment, the oblique edges 12 and 14 are oriented at an angle of 45 degrees to the long sides of the rectangle R.

It can also be seen that the axis of symmetry S of the trough base 5 extends at an angle of 5 degrees to the long sides of the rectangle R.

Furthermore, the outside 7 of the edge, as seen in the projection onto the installation surface 8 of the tub, is provided on the front 9 in the region of the head end 1 with a recess 15 which deviates from the rectangle R and which is formed by the edges 16 and 17 is limited. Through this recess, the width B₂ of the tub in the area of the head end 1 is also reduced to a dimension of 55 to 60 cm. In the illustrated embodiment, the width dimensions B₁ and B₂ are largely identical. However, this is by no means a mandatory requirement.

It can be seen that the outside 7 of the edge 3 forms a polygon, of which in the area of the recess 15 at the head end 1 a rear edge 16 runs parallel to the long sides of the rectangle R and that the edge 16 in the direction of the foot end 2 the front, oblique edge 17 is connected to the front long side of the rectangle R.

From Figure 2 it is also apparent that the edge 3 in the area between the recesses 11 and 15 has a lowered edge portion 3a. This measure serves to facilitate getting in and out of the tub.

It can further be seen from FIGS. 1, 2 and 3 that the side wall lying on the front has an armrest 18 in the area between the recesses 11 and 15. As a result, the slight displacement of the tub base 5 from the front 9 to the rear 10 is taken into account, and the volume of the tub cavity is used ergonomically in an ideal manner. Furthermore, a handle 19 is arranged on the edge 3, which the Has the shape of an upside down "U", one leg 19a is attached to the edge 3 and the other leg 19b is attached to the armrest 18. This is possible because the two legs 19a and 19b have different lengths.

It can also be seen from FIGS. 2 to 4 that the bathtub rests on or in a base element 20 with vertical outer surfaces 21, 22, 23, 24, 25, 26, 27, 28 and 29, which in the projection is with the outside 7 the tub rim 3 are substantially congruent. The base element is not only used to install the actual tub and to attach the cladding described above, as well as for thermal insulation, but it is also an important aid when transporting the composite consisting of tub and base element.

The projection of all edges, sides, planes, surfaces and points as projection lines or points in a horizontal plane, which is identical to the "footprint" and into which, is of essential importance for the description of the geometric connections with regard to the spatial form the reference rectangle (R) is placed for comparison purposes. In this way, the spatial shape of the tubs is compressed into a two-dimensional structure, which is meaningful with regard to the most protruding surface elements of the outer surface of the tubs. It plays for the movement of doors and the walk-in area speed of floor surfaces does not matter whether the tubs have an undercut in the immediate vicinity of the floor, into which you can step with your toes, for example. However, it does matter whether the outside of the tub has a protrusion above the floor, such as the step or the adjacent outer wall part in the tub combination according to DE-A-3 224 678, in which protruding parts lead to projection lines that outline or Enlarge the floor plan of the tub. This procection line (s) then clearly shows the stop for a door or the limit of the floor's accessibility. The line of all projection lines of the outer edges or outer sides of the upper tub edge of a conventional rectangular tub, which is circumscribed by a cuboid, on the installation surface is a rectangle, and this rectangle (R) is then the so-called reference rectangle. So it depends on the maximum dimensions of the tub over its entire height.

The shower tray according to FIGS. 5 to 7 has two side walls 101 and 102, a rear wall 103, a front wall 104, which has the polygonal course to be explained in more detail below, furthermore a bottom 106 provided with a drain opening 105 and an upper, circumferential, from which Sub-sections 107 and 107a existing edge, the sub-section 107 in an upper level and the sub-section 107a lowered to form an access opening 108.

The edge has an all-round outer edge 109, which, viewed in the projection onto the installation surface 110 of the shower tray, represents a polygon (FIG. 5). The outer edge 109 is outlined by a rectangle (R) which coincides with the outer edge 109 with the exception of the recesses which are explained in more detail below.

The shower tray 122 has in the region of the side walls 101 and 102 in a mirror-symmetrical arrangement two recesses 111 and 112 which differ from the rectangle R and which (again seen in the projection) are delimited by edges 111a / 111b and 112a / 112b relative to the tray. These recesses reduce the width B of the trough in the specific case by approximately 25% compared to the width of the rectangle R (dimension B + T).

It can be seen that the respective rear edge 111a and 112a of each recess 111 and 112 runs parallel to the front edge of the rectangle R, and that the edges 111a and 112a on the one hand open into the two side edges of the rectangle R and on the other hand through the front , oblique edges 111b and 112b are connected to the front of the rectangle R (Figure 5).

The length L of the edges 111a and 111b is approximately 16% of the length of the front of the rectangle R in the specific case. The recesses 111 and 112 reduce the width B of the shower tray in the region of the side walls to approximately 55 to 60 cm.

The illustrated embodiment can be described in a simple manner so that the polygon has eight corners, four corners 113, 114, 119 and 120 of which lie at the corner points of a second smaller rectangle which, with the first rectangle R, the two rear corners 113 and 120 has in common. Two further corners 115 and 118 lie on a straight line which connects the front corners 114 and 119 of the second (smaller) rectangle to one another. The polygon in turn forms two further corners 116 and 117, which lie in the front edge of the rectangle R. The position of two corners in each case is mirror-symmetrical with respect to the shorter axis of symmetry “S” of the rectangle R that runs perpendicular to the rear wall 103.

FIG. 5 also shows that, in the specific case, the oblique front edges 111b and 112b starting from the rear edges 111a and 112a run at an angle of 45 degrees to the front side of the rectangle R.

It can be seen in particular from FIGS. 6 and 7 that the side walls 101 and 102 and the rear wall 103 have a noticeably greater height than the front wall 104. As a result, a step is formed between the sections 107 and 107a of the edge, which step is divided into two vertical sections 107b of the margin. The subsections 107b simultaneously represent the vertical boundary walls of the entry opening 108 (FIG. 6).

As can be seen in particular from FIG. 6, the shower base has a base element 121 with a total of eight vertical outer surfaces, which coincide with the outer edges 109 in the projection according to FIG. As a result, only the outer surfaces 121a to 121f and 121g visible from the front are shown in FIG. 6; Figure 7 also shows the outer surfaces 121f and 121g. The outer surface 121g usually runs parallel to the bathroom wall in front of which it is placed. The base element is not only used to install the actual shower tray and to attach the cladding described above, as well as for thermal insulation, but it is also an important aid when transporting the composite consisting of the tub and base element. FIG. 7 also shows the measure of the height difference H between the sections 107 and 107a of the edge. Figure 7 is to be evaluated to scale.

Figure 8 shows a perspective view of the bathtub 21 in a corner of a bathroom with a door 22. The dimension M between the hinge axis of the door and the corner of the room is even significantly smaller than the width B₁ in the area of the recess 11. Nevertheless, the door can be open a sufficient angle without wasting space between the bathtub 21 and the corner of the room 23. At the opposite end of the bathtub 21 there is a shower tray 122 which leads through has visible or translucent cabin structure 123. The contact surfaces of shower tray 122 and bathtub 121 are congruent, so that optically the picture of a unit of bathtub and shower tray results. It turns out that an optimal use of space is possible when using the bathtub according to the invention. Compared to the recess 15, which continues in the area of the shower tray 122, a toilet or bidet can be attached, for example, without a too narrow aisle being formed in between. It is a series arrangement of a common installation wall, wherein a side wall 101 or 102 of the shower tray 122 directly and flush abuts an equally large head or foot end of the bathtub and the trays 21 and 122 are connected to one another in a sealed manner at the joint ST . This has the significant advantage that no water or dirt can penetrate into the joint between the shower tray and bathtub. While in the illustrated case the shower tray is attached to the head end of the bathtub, there is naturally also the possibility of attaching the shower tray to the foot end of the bathtub. This naturally results in a space in the form of a triangular prism in the area of the bathtub, which can be filled by a piece of furniture of complementary dimensions.

In any case, there is an optical picture of a unit consisting of a bathtub and shower tray. It turns out that optimal use of space is possible when using the shower tray.

According to FIG. 8, the cabin structure 123 consists of transparent elements 126, 127, 128 and 129, two of which are lateral elements 126 and 127 above the side walls 101 and 102, and two front elements 128 and 129 serving as a door are arranged above the front wall 104 of the shower tray 122 are. The projections of the elements 126 to 129 on the installation surface 10 of the shower tray lie within the projection of the edge 107 and 107a.

It can also be seen that the two lateral elements 126 and 127 are mirror-symmetrically L-shaped and the front elements 128 and 129 are designed in accordance with the polygon shape of the front wall 104 of the shower tray 122. Hinges 130 are located at the joints of the front and side elements. One of these hinges 130 is explained in more detail in FIG. The hinges serve to pivot out the front elements 128 and 129, which are formed in horizontal section as two-leg angle elements, the legs of which enclose an angle of 135 degrees. The height difference between the sections 107 and 107a of the edge of the shower tray 122 shows that the front elements 128 and 129 have a height which is approximately "H" larger in FIG. 7 than the lateral elements 126 and 127. The upper edges of all elements however, are on a common level.

The lateral element 127 shown in FIG. 9 is fastened to a wall 132 of the bathroom by means of an angle piece 131. The angle piece 131 has a simple leg 131a and a double leg 131b, between the plane-parallel halves of which the lateral cabin element 127 is inserted. An elastomeric sealing strip 133 is located between the vertical rear edge of the element 127 and the wall 132. The spatial fixing is carried out by screw connections known per se, the screw axes being symbolized by the dash-dotted lines.

FIG. 10 shows that a lip seal 134 is arranged between the lateral element 127 and the partial section of the edge of the shower tray, which prevents the splashing water that occurs during showering from escaping to the outside. It is understood that such lip seals 134 are arranged between all the elements 126 to 129 and the subsections 107 and 107a of the edge.

11 also shows the following: The lateral element 127 and the front element 129 (door) of the cabin structure 123 are connected to one another in the region of the vertical section 107b of the edge by a series of hinges 130, the axes of which run perpendicularly.

Each hinge 130 consists of a fixed hinge part 130a connected to the side element 127 and a movable hinge part 130b connected to the front element 129. As a result, the front element 129 (door) can be pivoted or opened by a pivoting angle of 90 degrees. This swivel angle is indicated by the circular arc 135.

FIG. 11 also shows that a sealing strip 136 is arranged between the vertical edge of the side element 127 and the adjacent vertical edge of the front element 129.

The construction according to FIGS. 9 and 11 can of course also be found in a mirror-symmetrical arrangement on the opposite side of the cabin structure 123, as can easily be seen from FIG.
