Description

The innovation relates to a corner protection element for component-enclosed Inneneck lining a room interior corner according to the preamble of the protection claim. 1

To protect inside corners, which are mainly equipped with a maintenance joint, it is usually necessary to protect the inside corner against fungal attack, against contamination, damage and breaking up.

Such maintenance joints are usually used in sanitary objects, such. B. the execution of a Inneneck training in a shower cubicle, the connection of a bathtub rim to an inner corner in a sanitary object and the like.

In the present innovation, it is assumed that a room inside corner is formed of three angularly abutting surfaces, it is not assumed that the room interior corner is equipped with permanently elastic maintenance joints. Also, it is not absolutely necessary that the three abutting surfaces at angles each form an angle of 90 degrees to each other. For the sake of simpler description, however, it is assumed in the following from such a room situation.

To cover room interior edges, it is from the DE 20 2005 015 386 U1 known, which describes a wall-ceiling wedge profile, which cooperates with corner elements.

Here it is assumed that splines 10 in a corner element 14 be inserted so as to achieve by blunt insertion into the corner element a corner joint, consisting of three abutting wall-ceiling wedge profiles.

In this case, it is a prerequisite that the wall-ceiling wedge profiles are fastened in the corner of the room even with corresponding adhesives or other fastening means, and consequently the known covering device for room interior edges is only suitable for a large-area covering of abutting room interior edges.

The document assumes a total of four different parts that need to be connected together, which is associated with a high manufacturing and assembly costs.

With the subject of DE 10 2008 007 478 A1 is known from plastic profile part known in which a cladding of edge portions of an outer corner takes place in such a way that at an angle of 90 ° splayed legs of the profile part engage behind a tile structure and a front, rounded profile part lining the room outer corner.

Such an installation is therefore suitable only for the covering of room corners.

In the DE 299 05 821 U1 An edge protection strip is integrated into a tile structure to provide corner protection. This is preceded by a grip behind the tile construction.

The DE 298 20 687 U1 describes a rail to be anchored between tiles and masonry with a plurality of mutually projecting legs, which form a slide-in profile for a longitudinally extending corner termination strip to be inserted there.

Again, it is assumed that the rail is installed in the area between masonry and tiles.

The novelty is therefore the object of developing a component-internal corner training with a corner protection element of the type mentioned so that with little effort a simple lining of an inner corner of a room is given without the need for anchoring further retaining means on the masonry.

To solve the problem, the innovation is characterized by the technical teaching of claim 1.

An essential feature of the innovation is that the corner protection element consists of a singular body, which has a visible surface and on which a body part is formed in the direction of the interior corner, which engages positively as possible from the visible side in the room interior corner and can be anchored there.

With the given technical teaching, there is the significant advantage that now a single, about button-sized corner protection element is described, which simply in a room inside corner of the visible side (ie from the front) engages and forms a form-fitting to the existing walls there.

The diameter of the visible side of the corner protection element is approximately in the range of the diameter of a 1 cent coin to the diameter of a 50 cent coin.

The term "singular twill" as part of the technical teaching of claim 1 means that the inventive corner protection element just not as an elongated rail or as over the room interior corner in the space surfaces extending part is formed. Rather, its size is limited to the lining of the room interior corner. A surface extension in the subsequent wall areas is rather not sought.

In a preferred first embodiment of the invention, the corner protection element is therefore designed as a tetrahedral body, i. H. it is a truncated cone body, in which the base surface of the truncated cone forms the visible side of the corner protection element, which is directed out of the inner corner and reach the adjoining frustoconical surfaces into the corners of the room and create a form fit on the corners of the room.

In a further embodiment of the present invention, it is provided that instead of a tetrahedral body (truncated cone body) a semicircular, lenticular or spherical body is used which has an adjoining, preferably conically tapering mandrel part at its front, visible part the room corner engages and forms a form-fitting manner on the local surfaces.

Instead of such a fully symmetrical body (which may also be rotationally symmetrical), spherical bodies can be used, so that out of the corner instead of a Linsenkopfes or a semicircular head and a round head (ball head) stands out, at the back of the aforementioned Dorn connects, which engages in the corner of the room and forms a form fit on the sides of the room.

Of course, the innovation also provides a variety of modifications of the tetrahedral body (truncated cone body), all of which should be included in the subject of the present innovation.

According to a preferred development of the innovation, it is provided that the anchoring of the previously described corner protection element (in all previously described embodiments) by means of a permanent elastic plastic maintenance gap in the corner of the room.

For this purpose, it is provided that the maintenance joint consists of a permanently elastic sealant, which sealant z. As silicone sealant, acrylic sealant, polymeric sealants or foamable sealants such. As polyurethane foams can exist.

In this case - when using a maintenance joint with the above-mentioned materials - it is particularly easy to anchor such a corner protection element in the corner, because before the sealant, which is to line the inner corner, hardens, the corner protection element according to the innovation pressed into the not yet cured sealant and connects there with the (not yet cured) sealant and is therefore fixed in this way in the inner corner and secured against falling out.

Therefore, the innovation describes a corner protection element, which achieves a component connection to permanently elastic maintenance joints, in which it is anchored in such a permanently elastic maintenance joint before curing. Thus, the trained so Inneneck training is protected against contamination, they can not tear anymore, and it is above all easier to clean.

However, the innovation is not limited to the integration of the inventive corner protection element in a filled with seal maintenance gap in an inner corner.

In another embodiment, the maintenance joints can be omitted, and the corner protection element can be pressed as such in an existing room corner with abutting wood surfaces, plastic surfaces, natural stone, metal surfaces, with a preferred anchoring of the corner protection element takes place on such hard materials in that the rear side of the corner protection element is formed with at least one central bore, a roughening, a depression or another anchoring surface, into which a hardenable adhesive or a sealant can be introduced or adhered.

The corner protection element is pressed into the corner of the room with the adhesive or sealant not yet cured, and the adhesive or sealant hardens there, so that the corner protection element lines the room interior corner consisting of hard components and protects them against dirt and damage.

Of course, the innovation is not limited to that the adhesive or sealant is introduced into a central bore at the back of the corner guard element.

In another embodiment, it may be provided that the rear surfaces of the corner protection element, which reach into the room interior corner, are provided with roughenings, grooves, projections or recesses, which may even barb-like, so that the corner protection element with barb-like projections or the like. Can be driven into a corner of the room and it does not require the use of a sealant or adhesive for anchoring.

There are various embodiments for the visible surface of the corner protection element according to the invention, all of which are claimed as essential to innovation of the present innovation.

In a first embodiment, it is provided that the pyramid base of the tetrahedron body forms the visible surface and this visible surface is smooth and continuous flat.

In another embodiment of the innovation, however, it may be provided that this visible surface is formed in any desired manner. You can z. B. convex or convex or concave or formed differently shaped in any way.

However, this applies not only to the visible surfaces of the tetrahedron body, but also for all other shapes claimed corner protection elements, which - may be formed - as described above - as a lens head, half-round head or ball head.

Therefore, it is possible to form a tetrahedral body on its base side, which forms the visible side, also with a lens head or a ball head.

In a preferred embodiment of the innovation, it is provided that the corner protection element consists of a suitable metal material, in particular a stainless steel material.

However, the innovation is not limited to this. The corner protection element may consist of any materials, all of which are suitable for a structural lining of a room interior corner, such. As light metal alloys, plastic, wood, plastic-wood combinations, plastic metal combinations and the like.

So it is only important that a component lining of a room interior corner is carried out with the corner protection elements according to the invention, which corner protection element should provide easy cleaning of the inner corner and protection of the inner corner against damage and soiling.

The subject matter of the present innovation results not only from the subject matter of the individual claims, but also from the combination of the individual protection claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the three-dimensional design shown in the drawings, are claimed as essential to the novelty insofar as they are novel individually or in combination with respect to the prior art. In the following, the innovation will be explained in more detail with reference to drawings illustrating several execution paths. Here are from the drawings and their description further innovation-essential features and advantages of the innovation out.

13 a modification of a tetrahedral corner protection element according to the 8th to 10 with corner pits

In 1 and 2 is a first embodiment of a corner protection element 1 shown, which is a room interior corner 7 lining. This is where a wall surface of a wall meets 2 with a bottom surface of a soil 3 at an angle of approximately 90 degrees together and thus form a corner of the room, like it 2 shows.

As an example, it is shown that it is a sanitary wall surface, in which a vertical maintenance gap 4 and two horizontal maintenance joints at an angle to each other 5 and 6 available. They all bump into the room's interior corner 7 together, and in this area is the modern corner protection element 1 thereby in the maintenance joints 4 - 6 fixed in which it is in the uncured condition of the maintenance joints 4 - 6 is pressed into the material of these maintenance joints, so that thus component-fitting transition areas 8th between the visible side 9 the corner protection element 1 and the adjoining surfaces of the maintenance joints 4 - 6 result.

The innovation is not limited to such an anchorage. Instead of a permanently elastic maintenance joint and other types of joints can be used, such. B. movement joints, which interrupt components to avoid stress cracks or expansion joints. All types of joints are suitable to provide a Inneneck training, which is lined with the inventive corner protection element.

What is important is that transition surfaces 8th according to 2 at all subsequent maintenance joints 4 . 5 . 6 result, so that a tight and form-fitting adjustment of all sides of the corner protection element 1 to the inner corner 7 converging maintenance joints 4 - 6 results.

As a modified embodiment, it has been pointed out in the general description that it is not necessary, the corner protection element 1 in the area of maintenance joints 4 - 6 to anchor.

It can therefore from the 1 and 2 be deduced that the maintenance joints 4 - 6 omitted and the corner protection element 1 directly into a corner of the room on the area of the adjoining walls and floor 2 . 3 is hammered or knocked in order also by a component-fitting system to the wall and floor surface 2 . 3 to provide.

Instead of the turning of the corner protection element, it is also possible, such a corner protection element in the room interior corner 7 glued.

For this case, see the 3 and 5 one - at the back as a tetrahedron 12 trained corner protection element 1 arranged - center hole 13 before, which can be filled with a curable adhesive, a putty or a sealant, so as to the corner protection element in a not self-lined with maintenance gaps room inner corner 7 to anchor.

In a third embodiment of the innovation, it may be provided that in the in the 3 . 5 and 6 illustrated back center hole 13 , which is preferably designed as a threaded bore, a threaded mandrel is screwed, which then in the room inside corner 7 shows. Its rear tip is directed into the room interior corner, so that the corner protection element with the screwed-in tip element can be driven or pressed into the corner and anchored there.

Based on 3 to 7 is the further construction of the first embodiment of a corner protection element 1 described.

As can be seen from the figures there, it is a tetrahedron 12 , the one flat visual side 9 which is the base side of the truncated cone body, being on this visible side 9 obliquely directed towards the center, uniform side surfaces 10 connect, whose edges are broken and by connecting surfaces 11 are bridged.

It goes without saying that the symmetrically formed tetrahedron consisting of equal areas 12 in his training as a corner protection element 1 also unequal large surfaces 10 can have. In this case, it would then be an asymmetric tetrahedron, which is also included in the present invention.

It is important that the cone tip is broken and in this area the center hole 13 is arranged, which extends over a certain distance in the body of the corner protection element and is designed as a blind hole. Such a central bore is initially regarded as an auxiliary bore, which is preferably introduced for easier production of the corner protection element. The corner protection element can therefore be easily clamped during manufacture and machined when a retaining pin is screwed into the center bore, which is suitable for receiving in a clamping or holding tool.

A second advantage of attaching the center hole results from the fact that if the center hole 13 equipped with a thread, it is also possible to screw in there a threaded bolt with its tip from the apex of the cone sticking out. This makes it possible, so equipped corner protection element with its screwed (or glued) tip in an otherwise non-lined room inside corner 7 collect and anchor there.

The 11 and 12 show as another embodiment, a rotationally symmetric corner protection element 21 . 31 , according to the embodiment 11 from a lenticular or hemispherical or convex viewing surface 14 consists, which is fully formed, which is attached to this visible surface 14 a thorn 15 connects, the outer circumference with grooves 16 or threads is equipped.

Even such a lenticular or hemispherical body can be used as a corner protection element 21 be used.

The same applies to the spherical body after 12 where it can be seen that a ball head 22 on its back with the thorn 15 Materialeinstückig is attached and the mandrel 15 again scored 16 or has threads.

Again, it is possible, such a corner protection element 31 by penetration and anchoring of the thorn 15 either in hardenable maintenance joints 4 - 6 to anchor. Alternatively, the thorn 15 in non-lined room interior corners in the transition area between the wall 2 and the floor 3 be driven in order, in this way - omitting the maintenance joints - the corner protection element 21 . 31 in the room interior corner 7 to anchor.

The 9 to 13 Now show various modifications of the tetrahedral shape after the 3 to 7 ,

First, it can be seen from the previous figures that the corners of the tetrahedron are flattened and so-called Eckenabflachungen 24 train to an even better positive anchoring to the adjoining surfaces of the maintenance joints 4 - 6 or the wall and room surfaces 2 . 3 to reach.

In the modification of this form shows the 8th that instead of the corner flattening 14 also lace corners 18 Can be used so that the corner flattening 24 omitted.

The 9 shows that the corners flatten 24 can also be designed as a radius and corner rounding 17 form.

The 10 shows that instead of an equilateral tetrahedron 12 With the same surfaces and unequal tetrahedral bodies can be used, in which z. B. the side edge 19 is longer than the angle adjoining further side edges 20 ,

Even with this non-uniform tetrahedral shape all previously described corners training are possible.

As the last embodiment shows the 13 in that the corners can also have broken out and so-called corner depressions 23 can form to acute-angled anchoring surfaces, which are even better in permanently elastic, not yet cured maintenance joints 4 - 6 dig in and anchor there.

Of course, the embodiments do not show that the visible surface 9 of the tetrahedron 12 can also be semicircular, convex, domed or otherwise formed. The innovation is therefore not limited to the illustrated embodiments, as already described in the general description part.
