Description

The present invention relates to a kitchen worktop with a broken by at least one recess for mounting a sub-element work surface.

The present invention also relates to a substructure element, in particular a sink, for attachment to a kitchen worktop according to one of claims 1 to 9, having at least one wall.

Finally, the present invention relates to an assembly consisting of a kitchen countertop with a by at least one recess for mounting a base element, in particular sink, interrupted work surface and attached to the kitchen worktop below base element.

Kitchen worktops of the aforementioned type are often made of natural stone, quartz composite, ceramic or Dekton and provided with sub-elements, usually rinsing. This results in the transition region between the sink and the kitchen worktop in the prior art, a V-shaped joint. This is due to the fact that due to the brittleness of the aforementioned materials for the kitchen worktops edges must be chamfered to produce a clean edge, which correspond to the prevailing in the kitchen aesthetic requirements. On the other hand, the rinses according to the prior art, due to their production, typically run upwards in a rounded-off manner in a deep drawing process. For aesthetic as well as hygienic reasons, the resulting joint must be closed in the prior art. This is typically done with silicone.

A disadvantage of the conventional kitchen countertop, sub-elements and assemblies is that initially the resulting silicone closed joint is often aesthetically undesirable. In addition, there is the problem that can accumulate on the silicone germs and bacteria. Finally, silicone joints are disadvantageous maintenance joints, which must be renewed repeatedly. However, since in the kitchen area the claim of absolute hygiene, but at the same time aesthetics play a major role, the present invention, the object of a kitchen worktop, a sub-element and an assembly of the type mentioned above, which improves in terms of hygiene and aesthetics are and are also low maintenance.

This object is achieved with respect to the kitchen worktop with a generic kitchen worktop, which has an extension of the recess inwardly delimiting edge, with which a wall of the base element is flush arranged. The fact that in the kitchen worktop according to the invention, the wall, for example, the sink flush with the inner edge of the recess for the sink can be flush, advantageously eliminates a joint. Accordingly, it is according to the invention not necessary to use silicone and the disadvantages described above in terms of hygiene and aesthetic appearance can be circumvented surprising.

In a preferred embodiment of the kitchen worktop according to the invention, this consists in an area of the recess at least in sections of natural stone, quartz composite, ceramic, Dekton and / or a brittle material. The aforementioned materials are particularly popular in the field of high-quality kitchens for aesthetic reasons. At the same time a joint-free connection between sink and Kitchen countertop has not been possible with kitchen worktops made of the materials mentioned above, since the brittleness of the materials leads to unclean edges, which is why chamfers have been made, which give rise to a joint.

In a kitchen worktop according to the invention, in a preferred embodiment, a surface normal of a chamfer area adjoining the edge can be aligned at an angle other than 90 ° to a surface normal of the work surface. The chamfer resulting in this way advantageously defines an edge which delimits the extent of the recess inwardly and with which the wall, for example the sink, can be arranged flush. The chamfer formed thereby further configures the kitchen worktop according to the wishes of the customers who prefer a custom kitchen equipment. In addition, the chamfer significantly reduces the risk of injury during assembly of the kitchen worktop, since non-chamfered surface edges of the aforementioned materials are often very sharp-edged and prone to chipping.

If the above-described angle is smaller than 90 °, an advantage of this embodiment is that the functional property of the chamfer portion is extended so that liquids can drain from the kitchen worktop into the recess provided for a sink. Thus, the formation of stains, which is critical especially for some natural stones, can be prevented.

In a preferred embodiment, in a kitchen worktop according to the invention, the chamfer area can be configured adjacent to the work surface. In cross section, the kitchen worktop according to the invention receives in this way a wedge shape, starting from the working surface starting a flattening up to the expansion the recess extends inwardly delimiting edge. In addition, a risk of injury can also be reduced if the user works on a kitchen worktop according to the invention.

A kitchen worktop according to the invention may be designed so that a thickness of the kitchen worktop is formed smaller in the vicinity of the recess than outside the recess. For example, in a ring arranged around the recess by milling a step in the bottom of the kitchen worktop be formed. Such a reduction in strength also makes it possible, with a kitchen worktop with great strength, to produce an edge which delimits an extension of the recess inwardly, with which a wall of the base element can be arranged flush. In addition, the inventive reduction in plate thickness reduces the chamfer surface, which may be desirable, particularly for large plates, where small chamfer surfaces are often preferred for aesthetic reasons.

In a preferred embodiment, a kitchen worktop according to the invention can be configured such that the working surface is formed without impact in the transition area from the environment of the recess to the area outside of the environment of the recess. Thus, there is a continuous flat work surface, which has no steps. This improves the kitchen worktop in terms of hygienic requirements, since the described bum-free design has no difficult to clean corners and edges.

The kitchen worktop according to the present invention can be advantageously configured such that the surface opposite the working surface in the vicinity of the recess and / or an abutment surface aligned substantially at right angles to the working surface is formed for the preparation of an adhesive bond, in particular roughened. Consequently, a sink can advantageously be glued to the underside of the kitchen worktop according to the invention by, for example, a two-component adhesive, the sink forming no joint with the underside of the kitchen worktop according to the invention. A roughened enlarged and partially cleaned contact surface improves the adhesion properties of the corresponding adhesive bond. By an additionally produced by milling, substantially rectangular, abutting surface on the underside of the kitchen worktop according to the invention, a further provided for gluing a sink contact surface can be generated. Thereby, a hollow profile between the outside of a sink and the substantially rectangular abutment surface on the underside of the kitchen worktop according to the invention can be adjusted and glued so that it relieves the adhesive connection of the sink at its end face. According to this embodiment of the kitchen worktop according to the invention, a hollow profile can be glued either to the underside of the kitchen worktop according to the invention and / or to the abutment surface of its underside, wherein it is additionally glued to the sink.

The object underlying the invention is achieved with respect to the substructure element with a generic substructure element, in particular sink, wherein an end face of the wall is designed flush with an edge of the kitchen worktop arranging, wherein the end face is preferably aligned in accordance with intended cultivation substantially parallel to the work surface. A sink designed in this way has an end face which is adapted to the shape which forms the underside of the edge defining the inside in the recess of the kitchen worktop according to the invention. The formation of a joint is thus avoided. The underside of the edge can be flat, so that provided for gluing forehead of the sink has straight edges. For example, a sink according to the invention can be made starting from a prior art sink having production-related radii of curvature in its upper part by separating its upper part by a plane cut. This allows the sink to be mounted without joints on the kitchen worktop according to the invention.

In a preferred embodiment, the sub-element relating to the invention may be designed such that a contacting element which enlarges the end face is provided in order to increase the contact surface with the kitchen worktop. The contacting element may for example consist of a hollow profile, one side of which is glued to the outside of a sink and the other side to the underside of the kitchen worktop according to the invention. As a result, the adhesive connection of the end face of the sink to the underside of the kitchen worktop according to the invention is mechanically relieved, whereby a tearing of the sink of the kitchen worktop according to the invention can be avoided. Since the wall of a sink is often very thin and thus the corresponding contact surface to the underside of the kitchen worktop according to the invention is small, provided in the invention contacting element is especially important when the sink is filled with water and dishes. In this case, the end face would be too small to be reliably fixed by means of an adhesive bond to the kitchen worktop according to the invention can

In the case of a substructure element according to the invention, the contacting element can preferably be designed such that it is designed as a profile element, in particular an angle profile, wherein preferably a first surface is fastened to the wall and a second surface for contact with the kitchen worktop is designed. In this case, for example, an edge of the angle profile, as can be produced for example by bending a sheet, be connected to the outside of a sink, while the other edge can be connected to the underside of the worktop according to the invention. Since profile elements are a common product, the described embodiment of the contacting element is inexpensive.

In the context of the invention, the substructure element according to the invention can be designed such that the contacting element is designed to contact the abutment surface and / or the surface opposite the working surface in the vicinity of the recess. Thus, one side of a hollow profile with flat outer surfaces can be adhered to the outside of a sink by means of a two-component adhesive, while the opposite surface of the hollow profile can be adhered to the abutment surface produced by milling on the underside of the kitchen worktop according to the invention. If the angular hollow profile along the flushing wall moved so far upwards that it touches the underside of the kitchen worktop according to the invention, creates a further contact surface with which the glued to the sink hollow profile can be adhered to the kitchen worktop invention. The hollow profile can be glued both to the abutting surface of the kitchen worktop according to the invention and to its underside, as well as to the abutting surface of the kitchen worktop according to the invention or to its underside, wherein it is additionally glued to the sink.

The problem underlying the invention is with regard to an assembly consisting of a kitchen worktop with a by at least one recess for growing a substructure element, in particular sink, interrupted work surface and one at the Kitchen worktop below fixed substructure element, achieved in that an end face of the wall of the base element is arranged flush with an extension of the recess inwardly bounding edge, wherein preferably the end face is aligned substantially parallel to the work surface. By according to this invention, a sink with a kitchen worktop is composed so that the inside of the wall of the sink is arranged flush with an extension of the recess inwardly bounding edge, so that no joint is formed.

Preferably, the assembly according to the invention can be configured such that the substructure is attached to the kitchen worktop cohesively, in particular by means of an adhesive bond. In this case, for example, a sink according to the invention is adhesively bonded to the underside of the worktop by means of a two-component adhesive, wherein the inside of the sink is arranged flush with the inwardly delimiting edge of the recess. Since the gluing requires no additional preparatory assembly work on the kitchen worktop according to the invention, hierein is an advantage of the assembly according to the invention by the assembly effort designed as correspondingly simple.

A further embodiment of the assembly according to the invention provides that a contacting element connected to the base element and the kitchen worktop is provided in order to fasten the base element to the kitchen worktop. As a contacting element, for example, a U-shaped profile can be used, which is glued to a sink and other surfaces on the underside of the kitchen worktop according to the invention using a two-component adhesive, so that no joint is formed. The mounted in this way U-shaped profile relieves the Adhesive bond between the face of the sink and the kitchen worktop according to the invention, so that the sink does not tear when it is filled.

In an assembly according to the invention, the kitchen worktop according to one of claims 1 to 8 and / or the substructure element according to one of claims 9 to 12 can be configured in a preferred embodiment.

The invention will be described by way of example in a preferred embodiment with reference to a drawing, wherein further advantageous details are shown in the figures of the drawing. Functionally identical parts are provided with the same reference numerals.
