Description

The invention relates to a repair kit according to the preamble of Claim 1 as a DIY kit for a window sill. The invention relates further comprising a window sill according to the preamble of claim 9 at least one cladding element forming a storage surface and at least one relining arranged behind it.

A large number of plates or plate bodies are practical known that form a horizontal storage or work surface for objects. Window sills or window sill panels, laboratory table tops, but also are known Tiles that can be used to clad floors or walls, or slabs as Shelf elements.

From practice it is known to be worked as a window sill use solid wood or stone. Stone windowsills in particular enjoy the slight tendency to damage their surface very popular. However, they are expensive to purchase and edit have an extremely high density and therefore a very high weight. Furthermore can never achieve an even quality of natural materials become. If a long windowsill made of several stone slabs is put together, clearly visible joints remain between the Plates. The cutting of stone is also without special tools and Experience problematic, so do-it-yourself damage and thus

are material intensive. Plates are also known from the practice of kitchen worktops, which consist of a plastic cover sheet on which a frame is glued from squared timber. Another narrow trim strip the same plastic is then applied perpendicular to the cladding sheet, and the resulting joint by application of not yet hardened Plastic removed, so that there is a seamless cladding element. The Squares used are heavy and usually do not allow full-surface relining of the plate, so that in larger areas of the plate Touches a hollow sound. Even the feel of such Plastic plates are, even with a noble presentation, that of a plastic.

For laboratory benches that are required to be acid resistant , it has been proposed to tile a surface and the relatively wide joints between adjacent tiles with a joint filler to seal. The edges of the underlay and the corner areas are included Angular or corner tiles are covered so that the edges are covered in any case. By covering it with a variety of shapes and shapes Shaped tiles are the well-known laboratory tables expensive and heavy.

For windowsills, in addition to solid stones, some are already multiple folded sheets have been proposed. These indicate when touched hollow and cheap acoustics. They are also sensitive to torsion, and out Manufacturing reasons always remain an optical in the corners annoying gap. Most sheets are also a few millimeters thick, otherwise they are the windowsill gets too heavy. After all, these sheet metal plates can only be through elaborate welding work or the like can be reworked. Furthermore sheet metal elements tend to form condensate on their invisible inside and consequently to corrosion. The surface of such sheets is suitable not to store heavy or large objects, as they are deflects.

A very special and long-standing problem is if existing window sill constructions have to be replaced, for example, due to damage or breakage, or because one Renovation of the room, e.g. due to new wallpaper, a visual adjustment and / or enhancement of the window sills may appear desirable. So far this problem has been solved by replacing the windowsill, e.g. stone, has been broken out of its anchorage, creating extensive Masonry was required. This is because of the length and effort of the Work as well as with the complete replacement of the base and window sill panel associated costs an unsatisfactory approach. Subsequently a new window sill panel was used, with the surrounding masonry connected by cement or mortar, followed by a rest period for the Harden. Then the masonry must be plastered or cleaned. A new wallpaper or a new coat of paint can only be provided after this. But since the color effect e.g. of a coat of paint only after application in one Housing is completely objective and subjective, often only after the renovation of the walls the need to renovate the window sills.

It is the object of the invention, a repair kit according to the preamble of claim 1 or a window sill according to the preamble of Claim 9 propose the possibility of easy repair of a Create windowsill element.

This task is carried out with the repair set mentioned at the beginning according to the characterizing features of claim 1 solved by a Cladding element with a substantially flat storage surface, and by at least one in appearance and feel on the cladding element coordinated and of its dimensions to adapt to that Covering element dimensioned, substantially perpendicular along a Edge of the shelf surface and side bar element to be arranged perpendicular to it.

This task is performed with the window sill mentioned at the beginning solved according to the characterizing features of claim 9, that the cladding element as a rigid and one-piece part with a Recess is formed on the side facing away from the storage surface, and that the relining is glued into the recess to be clad Windowsill element includes.

Furthermore, the invention proposes a method for cladding Window sills in front, which enables an inexpensive repair will that by means of an existing window sill element or part thereof of a system adhesive is cut to the appropriate size Cladding element is applied, with the unclad vertical Surfaces of the windowsill element with sidebar elements the same material as the cladding element by sticking to the Windowsill element and the cladding element are covered.

The repair set according to the invention is simple and saves volume transportable and also easy to stack. Across from The solid repair kit is lightweight and therefore light commissionable. The thickness of the shelf, the shelf surface of which is the visible one The top of the created window sill is slight so that it opens up the window is not affected.

The repair kit according to the invention is a DIY kit trained, and advantageously allows the renovation or repair of To offer window sills in the do-it-yourself (DIY) area at a reasonable price. Should repairs an existing window sill element in a building, for example become because it no longer fits the newly designed space, it is through the use of the repair kit according to the invention is no longer necessary, the tear out previous window sill element. Rather, the cladding element of the repair set tailored to the size of the window sill element be such that it with its surface facing away from the storage surface Window sill element just covered. If the windowsill element has an im bumper strip attached essentially at right angles to the storage surface, see above the inward-facing side also stops against the front side brought the window sill element. So that is the top and preferred the front of the window sill element is already covered. The fixation can be done by use a suitable adhesive; a supplied one is preferred for this System adhesive provided in a sufficient amount of adhesive for one Repair unit is packaged. Then that will Sidebar element cut to size to keep the eyes of the To disguise the exposed narrow sides of the window sill element. Since these are usually two narrow sides, often one of them walled-off part is to be subtracted, the sidebar element is first opened Cut to size and then also glued. The gluing can at the same time on the narrow side of the window sill element and on the Cladding element, preferably on the inward facing surfaces, respectively. If the cladding element does not have a bumper, the front of the window sill element is also covered in this way.

The repair set expediently comprises two side bar elements, which are each intended for one of the two narrow sides. This will make the number of cuts to be made by the handyman reduced, and at least two edges remain in the original processing the delivery before gluing, which makes particularly good Dimensional accuracy for gluing is achieved.

It is advantageous if the repair set further comprises a saw, which is adapted to the material to be processed, so that the risk of Selection of an unfavorable tool-workpiece pairing by the handyman is excluded.

Furthermore, the repair set preferably includes one for the Adhesion of the lining element sufficient amount (portion) of adhesive, e.g. a filling and also leveling system adhesive based on silicone, which adheres well to fairly smooth surfaces. This glue is conveniently housed in a dispenser or tube and enables a quick and cheaply dosed application. The e.g. based on PU manufactured adhesive advantageously allows the joints between to close butting parts that are barely perceptible, so that after connecting the trim element and the sidebar element appear in one piece without a joint.

According to an expedient training, it is possible to Repair set also to the dimensions of the trim element add adapted lining, as an intermediate link or as relining element between the trim element and the window sill element acts. This advantageously makes it possible to use the repair set equally adapt to window sill elements of different thicknesses without the Having to shorten the strips in the longitudinal direction. Rather, it can preferably layered lining are processed so that they Window sill element takes up. This can also be advantageous Create window sills, the depth of which is greater by a significant protrusion than the original windowsill element. The relining element is compared to the expensive material of the cladding element, whose "noble" look as Sales argument serves, inexpensive to manufacture and light in weight.

Through the preferred steps already outlined above for a repair of a window sill element can preferably Windowsill according to the invention are produced. The windowsill covers thus the cladding element and an underlying window sill element, that becomes invisible due to the covering of the other sides.

It is also advantageously possible that the lining instead of the Windowsill element includes a relining element, which accordingly is suitable, in the absence of the window sill element, e.g. because of his Destruction to act as a full panel as a windowsill replacement, causing in Defective windowsill elements in a room can be repaired and missing Windowsill elements can be replaced by the aforementioned plate, so that a harmonious, visually, haptically and sonically coordinated Together results. It is also possible to use a correspondingly thinner one trained lining height differences in differently worn Compensate windowsill elements.

In contrast to veneer coverings, the cladding element is rigid and formed in one piece. In the simplest case, it is Cladding element around a thin layer, but it is also possible that whose underside is designed like a cavity and at the same time a height of resulting window sill. To increase the rigidity can be provided that ridges on the back of the trim element the recess push through. The cladding element is thus advantageously a base that can be used without relining, similar to a strong sheet is. The cladding element already has the essential aesthetic and physical properties of a finished window sill.

The thickness of the cladding element is at most one third the thickness of the resulting window sill, which is a rich one after its manufacture Emits sound when knocking on the surface.

The cladding element is preferably a part made from one piece, for example by machining a block of stone or wood, or preferably a piece made from one part by archiving, for example by pressing, sintering or the like. It is possible that the one-piece piece is also created by assembling several components, for example welding, gluing, joining or screwing. Advantageously, however, it will be a composite material which is formed by a combination of stone or sand (SiO ₂ ) on the one hand and plastic on the other. With a suitable composition or processing, such a composite can take on a look very similar to that of natural stone, which also has other desired properties of stone slabs, in particular scratch resistance, good machinability, rigidity, insensitivity. Such a composite is inexpensive to manufacture thin compared to the corresponding processing of a natural stone slab, for example with the supply of heat in a corresponding counter mold. Since the underside is later lined with the relining, no post-processing needs to be provided for this; rather, the rough surface is particularly suitable for gluing. Optionally, to increase the rigidity of the cladding element, it is advantageously possible to reinforce the bond with a glass fiber matrix. Cladding elements of this type can be produced continuously in good quality and are free of microcracks.

According to a particularly preferred variant of the invention, this is Material of the cladding element can be repaired, i.e. that the fugue of adjacent portions of the trim element and one Sidebar element by a repair process, e.g. by ordering one appropriate material, e.g. a liquid silicone adhesive, at least like that be connected to each other so that the joint is no longer for human eye is recognizable. This will make the windowsill the prestige value particularly increased.

The lining advantageously comprises a relining element foamed rigid foam, according to the needs of the cladding element is cut to size. Preferably extends a one or multi-part relining element under the entire surface of the Cladding element. It is understood that the relining element also can be composed of several adjacent sections. But it is alternatively possible to design the relining element only as a frame that preferably runs along the side edges of the trim element.

According to a particularly preferred development of the invention the relining element comprises several layers or layers. Preferably layers are made of the same material, e.g. one Rigid foam material such as polyurethane. The layers are expedient different densities; this on the one hand enables extremely light layers in the relining element and thus into the window sill according to the invention integrate that fill the windowsill with minimal weight gain; on the other hand, it is possible in certain preferred locations, e.g. by doing Middle range of the thickness of the relining element, denser and therefore to provide more resilient layers. The denser layers, preferably one Density between 250 grams per liter and 750 grams per liter, with particular thin layers even up to 1800 grams per liter hold higher Tensile loads stood. In contrast to wood-based materials, polyurethane "burns" not the diamond dust trimmings that are typically used with saws for materials Stone is used. Thus, according to another aspect of the invention advantageously created a stone-containing windowsill with a diamond tool, e.g. saw blade of the repair set can be.

For example, from a repair kit of the aforementioned type a window sill made to measure according to the invention, this can expediently take place in that several according to the invention Cladding elements are first cut to fit the Dimensions of the window sill elements correspond, and glued to them become. Then the sidebar elements are glued. Then the joint between the cladding element and the Sidebar elements, if still required, by order of the the aforementioned adhesive removed.

As a result, it is inexpensive to have a windowsill to produce, whose look, sound and feel correspond to that of a stone slab, their repairability, weight and crack-free quality of a plastic plate corresponds, and their processability and assembly of a wood veneer panel corresponds.

Further advantageous embodiments of the invention are the the following description and the subclaims.

FIG. 2 is a cross section along the line II-II through the window sill of FIG. 1.

Fig. 3 is a cross section through another embodiment of a window sill according to the invention.

FIG. 4 is a cross-sectional view of a variant of the bumper strip of the window sill from FIG. 1.

Fig. 1 and 2 show an embodiment of an inventive Windowsill 10. With 11 a cladding element is designated, the outer (upper) storage surface is designated 11a and is about 5 mm thick. The Depth of the cladding element 11, that is the distance from the bumper to rear edge, is approx. 250 mm. Alternatively, widths of e.g. about 200 or 300 mm. The above dimensions are special advantageous because they allow many existing window sill elements of their Considered in terms of dimensions, with minimal waste. The width of the cladding element is in the present embodiment 1052 mm, alternatively 1020 mm or 2770 mm; these dimensions are off the same reasons as the aforementioned widths and especially in Combination with these preferred. However, it is possible to have special dimensions Tailor the plant, which are coordinated for special solutions.

At a substantially right angle to the storage surface 11a is a front strip 11b which is integral with the storage surface on the front trained, which is about 8 mm thick. In the joint area of parts 11a and 11b Storage surface 11a in an approx. 20 mm wide edge area approx. 8 mm thick, see above that a raised edge area is formed. The height of the bumper 11b (Internal dimension) is approx. 32 mm, so that there is an overall thickness of the window sill 10 in the front edge area of the storage surface 11a approx. 40 mm (external dimension) and in the central area of the storage surface 11a is approximately 37 mm. It is possible to change these dimensions by a few millimeters. The Cladding element 11 is preferably free of metallic components and therefore rustproof.

The lining element 11 is arranged on an underneath Window sill element 20 glued on. Any unevenness in the intermediate area 21 are equalized by a putty or a resin 22, which is also an adhesive acts between parts 11, 20.

At the lateral boundaries of the cladding element 11 the window sill 10 limited by sidebar elements 23a, 23b Cladding element 11 and glued to the window sill element 20.

In the present exemplary embodiment, the cladding element 11 and the side bar elements 23a, b consist of a composite material that was brought into its shape by means of archetypes. The material of the composite material is marketed in practice under the brand askilan®, and includes, among other things, a proportion between 20% and 80% granite, which, for example, as granite sand (SiO ₂ ) with other plastics to form a single-piece, rigid and thermally hardened with the addition of heat hard material composite is produced. But it is also possible to use processed natural stone or solid wood. It is understood that the material of the cladding element 11 advantageously has essentially the properties of a solid stone slab, i.e. temperature resistance, stability, insensitivity to cutting, insensitivity to impact, etc. The cladding element has a high density of approximately 1800 grams / liter, through which the average weight is approx. 9 kg / m ² . The weight can be between 6.5 and 15 kg / m ² , in particular depending on the granite content, with a corresponding thickness.

Fig. 3 shows another exemplary embodiment, in which the Dimensions of the newly created window sill 10 'differ clearly from those of the original window sill member 20 differ in terms of Depth and height. This is achieved by providing one Relining element 12 made of polyurethane, which balances the height and the depth. For this purpose the relining element 12 is e.g. with a Milling tool accordingly for receiving the window sill element 20 processed. However, it is also possible to remove the material to be removed, e.g. With To separate woodworking tools such as planes or the like.

The relining element 12 comprises in the present case Embodiment three layers 13, 14 and 15 adhering in pairs made of polyurethane foam and a lower lamination layer 16 made of paper. The (Upper) layer 13 of the relining element 12a is with the lining element 11 glued to the inner surface. The gluing is done by means of one sprayed or applied to the cladding element Polyurethane. By reaction with the layer 13 polyurethane foam in this case adherence of the polyurethane foam layer 13 to the cladding element 11, the binding forces being very high. It will be preferred Polyurethane glue also between the inside of the forehead and side strips 11b or 23a, b and the relining element 12 for producing an adhesive connection applied.

The use of polyurethane is advantageous because this material with both machining tools for wood (steel and carbide saws) as well as processing tools for stone (diamond-set Saws, cutting ceramics) can be processed without excessive tooling wear out. In this respect, polyurethane is wood as a relining material for consider stone-containing cladding elements. Therefore, preferably Wood-free materials for the production of the relining element 12 or the Windowsill 10 according to the invention used because the workability with diamond dust coated This enables sawing without excessive wear is. Furthermore, the use of polyurethane enables a good adaptation to the thermal expansion of cladding element materials such as stone, wood or plastic, so that thermal load on the window sill 10 induced internal stresses in the windowsill can be avoided as the Difference in thermal expansion is small. The use of the same Materials for all three layers 13, 14 and 15, here: of polyurethane, are aimed at the same Direction. By gluing on the underside of the surface 11a and on the Any manufacturing-related dimensional tolerances become inside of the bumper strip 11b balanced with the adhesive that reacts with the relining element 12.

The joints between the cladding element are preferably 11 and the side bar elements 23 with a silicone adhesive or the like. Or with a liquid plastic material, which is also part of the cladding element material is eliminated. The good processability and convertibility the window sill according to the invention and its light weight, its rich acoustics as well as their noble look and feel also due to the repairability and the The absence of gaps in the surface are tangible advantages.

The following is a particularly preferred manufacturing process for a window sill 10 according to the invention briefly explained.

To manufacture a window sill 10 according to the invention, a basic cladding element 11 with a working surface 11a is first produced by means of master shaping. The cladding element 11 is preferably a composite material made from at least one thermosetting plastic and a quantity of granite sand (SiO ₂ ) and further components. The trim element preferably also includes bumper strips 11b during manufacture.

To a surface like a polished stone surface too obtained, a sleep or polishing step is carried out after the primary shaping step executed in which a fine machining of the outside surfaces of the Cladding element 11 and in particular the work surface 11a and outer bumper 11b. Through the grinding or polishing step advantageously a better and more natural or natural look achieve a look and feel similar to that of solid stone. In contrast: to one raw surface can be repaired by machined surface with no emery stain left. This almost without a trace Repairability is a major advantage of the resulting invention Windowsill. In the same way, the side bar elements 23a, 23b.

For example, a rectangular base part with a circumferential Made bar, the covering elements can e.g. by sawing from the Base bodies are separated. Other parts of the base part can be in Strips are separated out to the intended side rails 23rd to manufacture. It is e.g. possible the sidebars of the future cladding element 11 to length. These steps are preferably carried out by machine or automated.

Cladding element and sidebar (s) then become one Repair kit packed, with other useful additions and expedient additions to the repair set made by purchased parts can be.

This repair kit is available in retail stores, e.g. DIY shops independently marketable and deductible. The following steps can therefore both by the craftsman and by the handyman.

First, a trim element 11 is made to the desired size tailored. This is preferably done on the basis of a finished one Cladding element 11, which only has to be "shortened" accordingly.

On the back of the shelf surface 11a of the trim element 11, an adhesive 22, preferably based on silicone, is applied. Alternatively, the adhesive 22 is applied to the window sill element 20. Then the two parts 11, 20 are glued, with the planar Alignment is respected.

It is possible to also glue one to the two beforehand Parts 11, 20 adapted relining element 12 as described above to stick, which at least partially acts as a coupling and compensation piece.

Finally, if they are not already with the Cladding element were integrally formed, the bumper and side strips 11b or 23a, b glued on. This will be due to the relining, on the one hand the window sill element 20 or, if necessary, the relining element 12, and for others also glued to the trim element 11. Preferably be the strips on inward-facing surfaces of the cladding element glued so that no joints from above (the usual viewing direction) are visible. Preferably, the joints with a resin or a thermosetting liquid plastic and subsequent polishing almost be made invisible.

Nase", umfassend die Stoßleiste 11b und rechtwinklig davon abstehend den Überstand von ca. 3 mm Stärke (vgl. Fig. 4). Diese Nase kann nun wieder leicht auf eine abgesägte Kante eines Verkleidungselements 11 angesetzt werden, indem die Unterseite des Überstands beispielsweise mittels Harz fugenlos auf die Ablageoberfläche 11a geklebt wird und der Rand 11b' mittels z.B. Silikonklebers 22 an der Unterfütterung, also Fensterbankelement 20 und/oder der Auskleidung 12, festgeklebt wird. Die seitliche Verkleidung erfolgt fugenfrei, und aufgrund der großen Klebefläche erfolgt eine gute Übertragung von Kräften, die der erfindungsgemäß hergestellten Fensterbank eine exzellente Robustheit vermittelt. Es versteht sich, daß das erfindungsgemäße Verfahren die Herstellung auch sehr komplizierter Geometrien von Fensterbänken ermöglicht. Ferner können sehr große Fensterbänke mit konstanter Qualität hergestellt werden, die auch wenn sie aus mehreren Verkleidungselementen 11 zusammengefügt worden sind, fugenfrei und von gleichmäßiger Optik sind, was z.B. bei Natursteinplatten nicht möglich ist. Es versteht sich ferner, daß die für die Stoßleiste 11b' beschriebene Vorgehensweise ganz genauso für die Seitenleistenelemente 23a, 23b ausgeführt werden kann.According to an alternative development, it is possible to glue the bumper strip 11b 'at the end of the assembly of a window sill to cover the edges instead of under the storage surface 11a. For this purpose, an edge piece 11b is first sawn off from a covering element 11 or a plate. The dividing line preferably runs along the somewhat thicker area of the cladding element, approximately 20 mm from the edge. Subsequently, the area that corresponds to the thickness of the cladding element 11 in the storage area 11a (ie approximately 5 mm) is milled away. This results in a

Nose ", comprising the bumper strip 11b and protruding at a right angle therefrom the protrusion of approximately 3 mm thickness (cf. FIG. 4). This protrusion can now easily be placed again on a sawn-off edge of a cladding element 11, for example by using the underside of the protrusion Resin is glued seamlessly to the storage surface 11a and the edge 11b 'is glued to the lining, for example window sill element 20 and / or the lining 12, for example by means of silicone adhesive 22. The lateral cladding is joint-free and due to the large adhesive surface there is a good transfer of Forces which impart excellent robustness to the window sill produced according to the invention. It is understood that the method according to the invention enables the production of very complicated geometries of window sills. Furthermore, very large window sills with constant quality can be produced, even if they consist of several cladding elements 11 have been added, are seamless and have a uniform appearance, which is not possible with natural stone slabs, for example. It also goes without saying that the procedure described for the bumper strip 11b 'can be carried out in exactly the same way for the side strip elements 23a, 23b.

The window sills 10, 10 'according to the invention are above have been explained in more detail using preferred exemplary embodiments. It it is understood that those skilled in the art can readily use the above Description found as equivalent or complementary means for Serve the same purpose, can also be used. So is it is possible, for example, to use the material densities and change thicknesses, or change the composition of the materials.

It is understood that also one manufactured according to the invention Windowsill can be repaired in the same way with another repair kit. Alternatively, the glued elements can be detached and replaced by the elements of a new repair kit. It is also understood that a Repair set can each include several of the parts mentioned, so that the professional windowsill repairer from a variety of available can select standing aids. So includes the invention Process, for example, the production of window sills and the like where several cladding elements form a common storage surface, or combined.
