Description

The invention relates to a corner element for achieving a wall closure and a sanitary device which is mounted in a corner area.

Joints in the edge and corner areas of bathtubs lose elasticity over time and settlement movements can occur. This can cause cracks. In addition, depending on the material, tile adhesive and mortar can absorb moisture. In the long run, these events can lead to water damage in sanitary installations.

There are numerous solutions in the form of sealing and finishing tapes that have been developed to ensure a clean and tight transition e.g. between a bathtub and an adjacent bathroom wall.

Some of the solutions offered are relatively expensive and a number of different steps must be carried out and the manufacturer's instructions must be followed in order to ultimately ensure the desired sealing effect in the long term.

Unfortunately, some of these solutions are not properly installed, or they are damaged if e.g. a grout is removed at a later time and new grout is injected. Errors are particularly common in corner installation, which can lead to leaks.

The corner installation is particularly problematic for bathtubs, shower trays and other sanitary devices, since these mostly have a radius in the corner area for production reasons. If you want to run a sealing or finishing tape flush around the "round" corner of the sanitary fixtures, this tape does not run parallel to the wall into the corner of the building. This leads to problems with the subsequent laying of tiles that extend parallel to the wall into the corner of the building.

In order to avoid problems when tiling, the wall edge of a bathtub to be installed in a building corner must be attached in a piece parallel to the wall along one edge of the bathtub into the building corner, around the corner and along the second edge of the bathtub adjoining the corner. Sanitary facilities such as bathtubs 10th (please refer 1A and 1B) and shower trays often, as already mentioned, have rounded "corners" 14 . The radius r1 is typically 14 mm and more. A corresponding example of a bathtub 10th is in 1A shown. In 1B is the tub edge using a bold curve 11 shown in a top view. The tub edge 11 here has a straight edge (viewed from left to right), which in the area of the rounded "corner" in an arc segment 14 with corner radius r1 transforms. On the right side, the circular arc segment goes into another straight edge 11 the bathtub 10th about. If the bathtub 10th in a building corner 3rd the two straight edges run 11 each parallel to the two wall sections that in 1B by two dashed tangents T1 , T2 are shown and the building corner 3rd form. One can see that there is between the building corner 3rd and the arc segment 14 the tub edge 11 a gap or a space ZR results. Now becomes one of the known sealing or end tapes around the circular arc segment 14 around to the back 12th the bathtub 10th glued, remains between this tape and the corner of the building 3rd the gap or the gap ZR essentially exist. If you try to install the tape in the corner of the building 3rd to glue in parallel to the two wall sections, while the tape also follows the round corner of the tub edge 11 follows, you have to put the tape under tension to get it into the corner of the building 3rd to be able to attach it to the wall. This can cause leaks. Sometimes the tape is also overstretched in the corner area to be able to connect it to the wall sections. As a result, cracks can form here. It is also known that craftsmen make cuts on the tape to better fit it into the corner of the building 3rd to be able to move inside. Some crafts also cut corners out of the tape in order to lay them in the corner of the building 3rd easier to design. However, this destroys the sealing effect of the tape.

The following aspect is aggravating. With a sealing or finishing tape with a simple, single-layer structure, this tape can be relatively simple the contour of the tub edge 11 a bathtub 10th consequences. Sealing and finishing tapes that are made of multiple layers (e.g. tapes that include a cut protection strip), however, tend to stick to the edge of the tub when they are glued on 11 in the area of the rounded "corner" 14 for wrinkling and warping, if the corner radius r1 the tub corner 14 is too small. It is immediately apparent that such a solution cannot be permanently sealed if you also try the tape in the area of the corner 14 tightly connect to the wall sections that the building corner 3rd form.

Leakages are therefore “preprogrammed” in many cases, especially in the area of a wall corner.

There are now solutions on the market that are suitable for corner installation, e.g. to make a bathtub easier.

The company Schaco AG, Switzerland, for example, offers several corner fillers made of butyl. The radius of the bath tub corner can be determined using the cardboard template provided. Depending on the radius, a butyl corner filler or several butyl corner fillers are then glued onto the relevant bath corner. With the butyl corner filler (s), a right-angled transition to the building corner can be done manually 3rd be formed, which bridges the gap ZR and which extends into the building corner 3rd extends.

Further solutions relating to prefabricated sickle-shaped filling elements are the European patent application EP2671489 A2 from the company Rivaplan AG. Other solutions can include the patent CH703416 B1 be removed. Prefabricated, crescent-shaped filling elements may have the disadvantage that if the wrong size of the filling element is selected, they are not suitable for creating a permanently sealed transition. In addition, different sizes must always be provided, which increases the logistical effort.

Another problem arises in the context described. Butyl or a butyl-like mass (such as recipes, which include other polymers in addition to a proportion of butyl) is preferably used as the material for the corner installation of sanitary fixtures. These materials are particularly suitable as sealants because they are impermeable to liquids, permanently flexible and (depending on the recipe) (self-adhesive). However, it has been shown that these materials can only be obtained from a few sources. The selection of shapes is also limited to yard goods that have a rectangular, square or round cross-section.

It is therefore the task to provide means for achieving a reliable and permanent sealing effect, which are designed for the corner installation of sanitary devices (such as bathtubs and shower bags). Above all, the corresponding solution should be universally applicable and less susceptible to incorrect installation or manipulation. It is also about providing a process for creating a simple and robust wall finish in the corner area, which leads to a reliable and permanent sealing effect. Furthermore, the invention is intended to make it easy to lay tiles right down to the corner area.

There is also the task of using the material in its available forms in such a way that a universally applicable solution can be provided with reasonable time and cost.

According to the invention, a corner element is provided which is designed for attachment to a sanitary device in order to enable a problem-free wall transition between the sanitary device and two wall sections which form the building corner when the sanitary device is installed in a corner of the building.

• - eine Stützvorrichtung mit zwei Schenkeln, wobei die beiden Schenkel im montagebereiten Zustand einen rechten Winkel bilden und einen Innenbereich aufspannen,
• - ein verformbares Füllelement, das von zwei wannenabgewandten Rückflächen, die einen im Wesentlichen rechten Winkel bilden, und einer Vorderfläche eingegrenzt ist, wobei die Vorderfläche die beiden Rückflächen verbindet,

wobei das Füllelement dazu ausgelegt ist vor oder während der Montage in dem Innenbereich zwischen den beiden Schenkeln so angeordnet zu werden,

• - dass sich je eine der beiden wannenabgewandten Rückflächen parallel zu einer der beiden Schenkeln erstreckt, und
• - dass die Vorderfläche vollflächig mit dem abgerundeten Eck der Sanitärvorrichtung verbunden ist.

The corner element of the invention comprises

• a support device with two legs, the two legs forming a right angle in the ready-to-install state and spanning an inner region,
• a deformable filling element which is delimited by two rear surfaces facing away from the tub, which form a substantially right angle, and a front surface, the front surface connecting the two rear surfaces,

the filling element being designed to be arranged in the inner region between the two legs before or during assembly,

• - That each of the two back surfaces facing away from the tub extends parallel to one of the two legs, and
• - That the front surface is fully connected to the rounded corner of the sanitary device.

For the purposes of the invention, a deformable filling element is a body made of a material or of a combination of materials, which is elastically deformable and / or plastically deformable during assembly. In principle, an elastically deformable material can return to its original shape, whereas a plastically deformable material under the influence of force after a flow limit has been exceeded begins to irreversibly deform.

Filling elements are preferred within the scope of the invention which have at least a certain degree of plastic deformability.

A form-fitting, intimate connection between the front surface of the filling element and the rounded corner of the sanitary device is considered to be a full-surface connection.

Particularly suitable for all embodiments of the invention are (soft) elastic closed-pore foam materials (such as expanded polystyrene foam) or (soft) elastic foam materials with closed outer skin (such as polyurethane foam), rubber materials, rubber-like materials, but above all butyl ( eg in the form of a butyl rubber), butyl-like materials or silicone. Combinations of two or more of the materials mentioned can also be used.

Filling elements can be used within the scope of the invention which, viewed in plan view, have an essentially triangular basic shape.

The triangular basic shape can - viewed in plan view - be delimited by three straight edges, or it can e.g. have two straight edges and an arcuate edge. The arcuate edge, if present, can have a concave or convex or multiple curved shape in all embodiments.

The filler element may not have through holes or recesses. These holes or recesses can extend into the material of the filling element from above, from below or from above and below.

When viewed from a top view, the filler element can have a basic shape with two rear surfaces which, when ready for installation, are at right angles or essentially at right angles to one another. In addition, the basic shape can be distinguished by the fact that it has an arcuate front (concave, convex or curved several times). The front is also referred to here as the tub side, since this side adapts to the radius and shape of the sanitary device during assembly.

In order to give the filler element a sufficient volume so that enough material is available that can be deformed, the filler element can preferably have a concave front side in all embodiments, the radius of which is larger than the radius of the sanitary device, before the assembly.

Filling elements which are in one piece or which are composed of two or more than two elements (e.g. a foam element which is completely or partially surrounded by butyl) can be used within the scope of the invention.

In order to be able to adapt the deformable filling element exactly to the round corner of the sanitary device, the corner element of the invention comprises a support device with two legs. When ready for installation, these two legs form an essentially right angle and they span an inner region.

Preferably, at least the two legs of the support device are inherently stable in order to be pressed against the deformable filling element from the outside during assembly. The two legs of the support device exert a force on the deformable filling element during assembly so that the shape of the filling element can adapt to the radius of the sanitary device by elastic and / or plastic deformation.

In addition, the support device can be useful during production (especially when shaping the material of the deformable filling element) and / or during transport.

The support device can be supplied as a right-angled element in all embodiments, or it can be supplied in such a way that it is changed to a right-angled element before assembly (e.g. by assembling, plugging, bending or folding).

The corner element of the invention is constructed in such a way that a sealing tape or wall sealing strip can be easily guided into the corner of the building. The support device can serve as a basis for adhesion serve for gluing or attaching the sealing tape or wall sealing strip. But it is also possible to remove the support device.

By using the corner elements according to the invention, it is possible to achieve high quality in terms of sealing in the corner area.

Further preferred embodiments can be found in the dependent claims.

A correspondingly equipped sanitary facility can be found in independent claim 9 and dependent claim 10.

In the following, location and directional information are used in order to better describe the invention. This information relates to the respective installation situation and should therefore not be understood as a restriction. In order to be able to better narrow down the location and direction, a reference to the tub is also used in some cases 10th (which is also to be understood here as an example for other sanitary facilities) or to the corner of the building 3rd produced in which, for example, a tub-side element and wall-facing surfaces are mentioned.

The term "sanitary device" 10th is used here, among other things, for bathtubs, whirlpools, shower trays, shower trays or plates, channels and sinks or tables. It does not matter what material (ceramic, mineral casting, metal, (natural) stone, etc.) this sanitary fixture is made of 10th is made.

It is especially about sanitary facilities 10th that have at least one rounded corner 14 (also called corner area) and at least in the area of the rounded corner 14 a waterproof and permanent wall closure, preferably using a sealing tape or Wall edge strip 40 , to be manufactured. The following is an example of a bathtub 10th Referenced unless otherwise stated.

According to the invention, it is a corner element 100 for mounting in the corner area between a rounded corner 14 a sanitary device 10th and a corner on the building side 3rd as exemplified in 8C can be seen in a schematic plan view.

In the 2A - 8B are several exemplary corner elements 100 shown the invention. The common features of these corner elements 100 are referred to below with reference to this 2A - 8B Summarily described. Details, by which the embodiments shown differ, are subsequently explained.

The corner element 100 includes a support device 20th with two legs 21.1 , 21.2 , with the two legs 21.1 , 21.2 form a substantially right angle when ready for installation. In the 2A - 7D , 8A , 8B , and 10th are the support devices 20th each shown in the ready-to-install, right-angled condition.

The support device 20th stretches between the two legs 21.1 , 21.2 an interior area IB as in 8A , 8B and 9 can be seen. In principle, this inner area IB can be defined by having the open ends of the two legs 21.1 , 21.2 with a fictional straight line G connects to a triangle, as in 8A , 8B , 9 , 11A , 11B , 12th and 13C indicated.

The corner element 100 further comprises a deformable filling element 30th , which in principle consists of two rear surfaces facing away from the tub 31.1 , 31.2 which form a substantially right angle and a front surface 31.3 is limited. In the 2A , 2 B , 2C , 3A , 3B , 5 , 7A , 7B , 7C and 7D are the top edges of these back surfaces 31.1 , 31.2 provided with corresponding reference numerals. The front surface mentioned 31.3 connects the two rear surfaces 31.1 , 31.2 directly or indirectly.

In the 2A , 2 B , 2C , 3A , 4A , 4B , 6 , 7A , 7B , 7C , 8A , 8B and 10th are embodiments with a direct connection of the front surface 31.3 with the two back surfaces 31.1 , 31.2 shown. These areas each form a common edge 32.1 , 32.2 . These common edges 32.1 , 32.2 are in the 2A - 2C , 3A , 4A , 4B , 6 , 7A , 7B , 7C provided with reference numerals.

In the 3B , 5 , 7D , 8C and 14 is an embodiment with an indirect connection of the front surface 31.3 with the two back surfaces 31.1 , 31.2 shown. The indirect connection results, for example, from chamfers 33.1 , 33.2 in the transition area of the surface 31.3 to the areas 31.1 respectively. 31.2 are provided.

The filling element 30th is specially designed before installation (e.g. ex works) or during installation in the interior area IB between the two legs 21.1 , 21.2 to be arranged in such a way that one of the two back surfaces facing away from the tub 31.1 , 31.2 parallel to one of the two legs 21.1 , 21.2 2A, 8C, 10, 14 and 15B.

In addition, the filling element 30th specially designed with its front surface 31.3 (if possible) all over with the rounded corner 14 the sanitary device 10th to be connected as in the top view of the 8C hinted at an example. The term “full-surface connection” here describes the fact that the surface 31.3 of the filling element 30th in all embodiments exactly to the shape of the corner area 14 is adjusted. The result is between the surface 31.3 and the tub edge 11 in the corner area 14 no gaps, gaps or air pockets. This full-surface transition is therefore absolutely tight.

The embodiments of the 2A , 2 B , 2C , 3A , 3B , 5 and 7C are particularly characterized in that the two legs 21.1 , 21.2 the support structure 20th a height hs that are larger than the thickness df of the filling element 30th . This results in above and / or below the filling element 30th an edge or heel on the thighs 21.1 , 21.2 .

The embodiments of the 4A , 6 , 7A and 14 are characterized by the fact that the two legs 21.1 , 21.2 the support structure 20th a height hs have that of the fat df of the filling element 30th corresponds.

The embodiments of the 4B , 7B and 7D are characterized by the fact that the two legs 21.1 , 21.2 the support structure 20th a height hs have less than the thickness df of the filling element 30th . These embodiments are preferred because of the protrusion of the filling element 30th a better connection with a sealing tape or wall edge strips 40 enables.

The embodiments of the 2A , 3A , 3B , 4A , 4B , 5 , 6 , 7A - 7D , 8A - 8C are characterized by the fact that the front surface 31.3 before pressing against the round corner area 14 each has an arcuate course. In all of these cases the front surface is 31.3 concave design. However, it can also be convex in all embodiments, or it can have a curved shape several times. These statements refer to the condition before assembly on the corner area 14 .

The embodiment of the 2 B and 2C is characterized in that the front surface 31.3 has a straight (flat) course.

In the 2A - 8C and 10th are various exemplary support devices 20th to recognize. Other exemplary support devices 20th without filling element 30th are the 9 , 11A , 11B , 12th , 13A - 13H refer to.

The following only deals with the essential aspects of these exemplary support devices 20th received.

In the 9 , 11A , 11B, 12 and 13C are the support devices 20th each shown in the ready-to-install, right-angled condition.

In 9 is a support device 20th shown on the wall side a butyl (strip) 25th includes. This butyl (strip) 25th can serve a tight connection to the wall sections 1 , 2nd to manufacture. A butyl (strip) 27 can additionally or alternatively also on the inside of the legs of the support device 20th be appropriate, as in the 2 B and 2C shown. This butyl (strip) 27 can serve a good connection to the filling element 30th to manufacture.

As in 9 in the area X1 As indicated, the butyl (strip) 25 can be on one or both legs in all embodiments 21.1 , 21.2 be slightly longer than the length of the legs 21.1 , 21.2 . That is, the butyl (strip) 25 may have a protrusion in all embodiments. When pressing the corner element 100 in a building corner 3rd , the protruding butyl material here along the vertical edges 26.1 , 26.2 of the support devices 20th ensure the required tightness. The corresponding vertical edges 26.1 , 26.2 are in the 11A , 11B , 12th , 13A , 13D , 13F and 13H provided with reference numerals.

As in 2C indicated, the butyl (strip) 27 in all embodiments on one or both legs 21.1 , 21.2 be slightly longer than the length of the legs 21.1 , 21.2 .

In 10th is a corner element 100 shown, which is constructed similarly to the corner element 100 of the 8A . It is therefore based on the description of the 8A referred. In 10th it can be seen that the thighs 21.1 , 21.2 the support device 20th Have end areas that run out at an angle. In 10th is the corresponding area of a leg 21.1 with the reference symbol X2 Mistake. Such a solution with flat tapered legs 21.1 , 21.2 enables an even better and closer connection with the sanitary device 10th on the one hand and the wall sections 1 , 2nd on the other hand.

In the 11A and 11B are support devices 20th shown, each a corner piece 22 includes. This corner piece 22 can serve for example the two legs 21.1 , 21.2 stabilize and the right angle of the support device 20th define. The corner piece 22 can also overflow the material of the filling element 30th up (in 11A) and / or below (in 11B) prevent when the entire corner element 100 towards the corner 14 the tub 10th is pressed. Such a corner piece 22 can also be centered on the support device 20th be provided, or it can be on the support device 20th more than just a corner piece 22 to be available.

In 12th is a support device 20th shown, which comprises an upper (horizontal) edge 23. That edge 23 can serve for example the two legs 21.1 , 21.2 stabilize and the right angle of the support device 20th define. The edge 23 can also overflow the material of the filling element 30th prevent upwards when the entire corner element 100 towards the corner 14 the tub 10th pressed becomes. Since no material can overflow here, it is particularly advantageous to place a round cord here, before then, as usual, below a tile mirror and the top edge of the bathtub 10th a silicone joint is attached.

Accordingly, a support device 20th additionally or alternatively also include a lower (horizontal) edge, which is not shown in the figures.

The In 12th shown upper margin 23 can also be shorter in all embodiments. This statement also applies to a lower (horizontal) margin, if available.

In the 13A and 13B is another support device 20th shown in a flat condition. In 13C is a corner portion of this support 20th shown in the ready to install (angled) condition. To the support device 20th Being able to bend the 13A - 13B is optionally a miter here 24th intended. If you look at the two legs 21.1 , 21.2 transferred into the angled shape, then the miter surfaces can serve as a stop to define a 90 degree angle, as in 13C shown.

In the 13D and 13E is another support device 20th shown in a flat condition. This support device 20th includes in addition to the miter mentioned above 24th two noses 28 . If the two legs 21.1 , 21.2 these noses are used 28 as a stop and for stabilization.

In the 13F and 13G is another support device 20th shown in a flat condition. This support device 20th includes in addition to the miter mentioned above 24th a right-angled nose 28 . If the two legs 21.1 , 21.2 this nose served to be angled 28 as a stop and for stabilization.

Supports 20th who have a nose or two 28 include, do not necessarily need a miter 24th to have. In these cases, a perforation or slit with a hinge effect is sufficient.

In the 13H is another support device 20th shown in a flat condition. This is, for example, a support device 20th from a thin (CNS) sheet. To achieve a hinge effect, a perforation can 29 be provided. In the case of metallic materials, such perforation can occur 29 can be generated, for example, by means of a laser beam. But support devices are also possible 20th made of plastic with an appropriate perforation.

In 8C is an installation situation based on an example after installing the corner element 100 shown the invention. The sanitary device 10th was in a corner of the wall 3rd positioned that by two wall sections 1 , 2nd is formed. The sanitary device 10th has a corner area 14 on, which serves as a transition between a longitudinal edge of the bath and a transverse edge of the bath. The corresponding tub edges are here with the reference symbol 11 Mistake. As in 8C was shown, a corner element 100 the invention so to the corner area 14 the sanitary device 10th molded onto the front surface 31.3 of the corner element 100 has a concave shape and that the front surface 31.3 fully sealed with the vertical surface of the sanitary device 10th in the rounded corner area 14 connected is. For pressing against the rounded corner area 14 became a corner element here 100 according to 8B used that in both end areas - here with X3 marked - each has an excess of deformable material. This excess material fills when the corner element is pressed on 100 any gaps that are in the end of the leg 21.1 , 21.2 the support device 20th could result.

When installing the corner element 100 care is taken that the two legs 21.1 , 21.2 the support device 20th parallel to the two wall sections 1 , 2nd run. Therefore, when attaching and pressing the corner element 100 made sure that each of the two legs 21.1 , 21.2 runs parallel to the corresponding longitudinal edge or transverse edge of the tub.

In the transition area from the long edge of the tub to the rounded corner area 14 and from the rounded corner area 14 to the edge of the tub, there is an apex. The two vertices P1 , P2 are in 8C shown. Ideally, the two legs intersect 21.1 , 21.2 , if you extend it in your mind with a straight line, after assembly with the respective apex P1 , P2 . In other words, the leg is preferably located 21.2 in alignment with the long edge of the tub and the legs 21.1 in alignment with the edge of the tub.

The following is an example of the assembly of a corner element 100 described the invention. Depending on the situation and current needs, the corner elements can 100 of the invention are provided in 2 or more than 2 different sizes. In this case, before performing the first step based on the corner radius of the sanitary fixture 10th a corner element 100 selected with the appropriate size.

In a first step, the corner element 100 with the front surface 31.3 of the filling element 30th at the corner area 14 the sanitary device 10th scheduled. The corner element 100 can in this phase, for example, in 8B have the shape shown.

In a subsequent step, a contact pressure P is applied over the two legs 21.1 , 21.2 on the filling element 30th exercised to the filler 30th through elastic and / or plastic deformation at the corner area 14 adapt. In 8C 2 block arrows indicate the application of the contact pressure P.

This step can be done without a tool or with a tool.

Because the thighs 21.1 , 21.2 the support device 20th are stable in themselves, an even contact pressure on the filling element 30th be exercised, even if the orientation of the two printing directions should not be exactly at right angles to each other.

When the contact pressure P is exerted, at least the front surface 31.3 of the filling element 30th deformed and it becomes the two legs 21.1 , 21.2 in an aligned position with respect to edges 11 the sanitary device 10th brought, as already described.

In 14 is an example of a further installation situation after installing the corner element 100 shown the invention, the bathtub 10th is deliberately not shown here in order not to hide the elements behind it. The sanitary device 10th (not shown) after installing the corner element 100 in a corner of the wall 3rd positioned that by two wall sections 1 , 2nd is formed. As in 14 was shown, a corner element 100 the invention so against the sanitary device 10th pressed and fixed there that the front surface 31.3 of the corner element 100 has taken on a concave shape. By pressing the corner element 100 against the sanitary device 10th became the material of the filling element 30th plastically deformed in the example shown so that on the one hand there is a full-surface, tight connection with the sanitary device 10th (not shown) results. On the other hand, in the X3 designated area (as also in 8C ) the material of the filling element 30th over the vertical edge 26.1 the support device 20th flowed to form a tight transition here too.

Embodiments are also possible in which the material of the filling element 30th is set at the factory so that it is the vertical edge 26.1 overlapped or covered (either as a butyl strip 25th (please refer 9 ) Butyl strips 27 (please refer 2 B , 2C ), the overlapping inside or outside of the support element 20th is attached, or as a filling element 30th that is longer than the thighs 21.1 , 21.2 of the support element 20th (please refer 3B , 7D )).

Furthermore, in 14 a length section of an optional sealing tape or wall sealing strip 40 shown. The sealing tape or the wall trim strip 40 runs around the two legs without interruption 21.1 , 21.2 around and can be glued and / or embedded in the corner 3rd in parallel with the wall sections 1 , 2nd to be connected.

By deforming the material of the filling element 30th , this adapts to the corner area 14 the sanitary device 10th and the shape of the space ZR. With a material that deforms plastically, the material can even flow into gaps or gaps.

Either is the front surface 31.3 of the filling element 30th designed in all embodiments as an adhesive surface, or it is before starting at the corner area 14 an adhesive on the front surface 31.3 of the filling element 30th and / or at the corner area 14 the sanitary device 10th appropriate.

Preferably the front surface comprises 31.3 a butyl strip or at least the front, tub-side area of the filling element 30th includes butyl. Since butyl has a good adhesive effect on smooth surfaces, pressing the corner element 100 a tight adhesive bond can be created.

In the 8A and 8B is a dashed circle segment K shown. This segment of a circle K has the same radius r1 like the corner area 14 the sanitary device 10th . If you have the current concave shape of the front surface 31.3 with the course of the circle segment K compares, you can see in both cases that the filler 30th deformed during pressing in such a way that in the central area there is a greater curvature inwards into the material of the filling element 30th arises into it. Material is therefore displaced in the middle area. On the right and left extensions of the filling element 30th (ie in the area of the edges 32.1 , 32.1 of the 2A , 2 B , 2C , 3A , 4A , 4B , 6A , 7A to 7D or the chamfers 33.1 , 33.2 of the 3B and 5 ), the material of the filling element 30th along the thighs 21.1 , 21.2 outwards (away from the corner 3rd ) pressed.

After the corner element 100 on the sanitary fixture 10th was attached by pressing, the sanitary fixture 10th together with the corner element 100 in the corner of the wall 3rd be positioned. It is obvious that before positioning in the corner of the wall 3rd further intermediate steps can follow, but which are not the subject of the present invention (for example, the support element can optionally 20th be removed). In an intermediate step, for example, a sealing tape or wall sealing strip can be used 40 at the edge of the tub 11 fastened and outside around the two legs 21.1 , 21.2 be led around. Such a sealing tape or wall sealing strip with the rear surfaces of the two legs on the wall is preferred 21.1 , 21.2 glued. Butyl can also be used here, for example. In 9 is a butyl (strip) on the wall for this purpose 25th intended.

To the support device 20th firmly with the wall sections 1 , 2nd , or with a composite structure of these wall sections 1 , 2nd to be able to connect, the wall-side rear surfaces can optionally have a well-adhering surface in all embodiments.

To the back surfaces 31.1 , 31.2 of the filling element 30th firmly with the front surfaces of the two legs facing away from the wall 21.1 , 21.2 to be able to connect, the two legs 21.1 , 21.2 in all embodiments have a well-adhering surface on the front side (front surfaces facing away from the wall).

The two legs 21.1 , 21.2 However, in all embodiments they can have, for example, an (embossed) grid or mesh structure, or they can be made from a grid or mesh material (see, for example, 7A - 7D ) to the filling element 30th fasten and on the other hand the wall-side rear surfaces with the wall sections 1 , 2nd or to be able to connect a composite structure, or a sealing or connecting tape.

Support devices are particularly suitable 20th made of metal and / or plastic and / or siliconized cardboard. The support device 20th can have smooth, well-adhering surfaces in all embodiments, or it can have other surfaces that are designed to be well-adhering (for example by sticking on fleece, by etching, roughening, sanding, by providing holes or openings, by making grooves , Slits or perforations and the like). Perforated sheets, expanded metals or other supporting devices 20th with holes and / or openings have the advantage that they allow an intimate connection with the deformable material, since this material is the support device 20th can penetrate at least partially in these cases.

The supports 20th In all embodiments, for example, as already mentioned, they can also have a superficial lattice or network structure (for example, produced by using an embossing or etching process). However, a superficial structure can also be specified, for example, using an injection molding tool.

In all embodiments, it can also be, for example, an expanded metal, perforated plate or a metallic lattice structure as a support device 20th be used.

The supports 20th In all embodiments, instead of a sharp-edged corner area, can also have a corner area that is slightly rounded or chamfered. With the support devices 20th of the 4B , 7D , 10th you can, for example, an outer corner area E recognize that is not designed with sharp edges.

In 9 it can be seen that the sharp-edged corner area of a support device 20th is easily rounded off by applying (gluing) a butyl (strip) 25.

The supports 20th form a right angle in all embodiments at least in the outer region, ie on the wall side. Inside IB, that of the two legs 21.1 , 21.2 is not necessarily a right angle.

The filling element 30th can consist of one or more than one material in all embodiments.

The filling element 30th can be on the front surface in all embodiments 31.3 and / or on the back surfaces 31.1 , 31.2 be designed to be adhesive. For this purpose it can, for example, be provided with an adhesive (such as butyl).

The filling element 30th can have a triangular basic shape with side edges in all embodiments, which can be longer, the same length or shorter than the length of the legs 21.1 , 21.2 the support device 20th .

The corner element 100 can be delivered ready for assembly in all embodiments, with any adhesive surfaces optionally being protected by a film or (for example siliconized) paper. The corner element 100 can also be delivered in individual parts in all embodiments, in order to then be assembled on site and then assembled.

Around a corner element according to the invention 100 To be able to produce a precise shape, a special process was developed, either from a short length of a deformable strip of material 203 with a round cross-section (see 15A and 15B) , or from a short length of a deformable strip of material 203 with a square or rectangular cross-section (see 15C ) goes out. The length of the length section corresponds approximately to the thickness df , the filling element 30th .

The length of a deformable strip of material 203 is specifically shaped using a die or mold. In 15A is an example of a sub-area of a machine 200 shown the a machine bed 201 with a right-angled neckline and a relatively movable stamp 202 includes. A support element is placed in the rectangular cutout 20th inserted and it becomes the length of a deformable strip of material 203 inserted into the interior, which results between the two legs, as in 15A shown.

Optionally, a film or a (siliconized) paper can be used in an intermediate step 204 be introduced so that the stamp 202 better from the strip of material later 203 can be separated. However, the stamp is also possible in all embodiments 202 designed to be non-stick coated, or to protect it from sticking with a thin film (e.g. with a special spray) or another suitable material.

In 15B is now shown as the stamp 202 with its underside (which is here, for example, convex) in the material strips 203 is pressed in order to deform the material plastically and / or elastically. Elastic forming may work at an elevated temperature to improve the material's formability.

To prevent the deformable material from escaping, the embodiments of the machine shown and described can be used 200 two additional jaws can be provided, which are attached statically in the machine, or which can be delivered in the machine.

After the step of 15B can the stamp 202 withdrawn and the finished corner element 100 be removed.

Such a machine 200 can be fully automated, partially automated or operated manually.

In 15C it can be seen that one can also use a length of a deformable strip of material 203 can work, which here has a square cross section, for example.
