Description

The present invention relates to a sink with an overflow opening in a sink wall and an overflow assembly arranged at the overflow opening, the overflow assembly comprising an overflow body and a cover element.

In known overflow assemblies for sinks, a fastening receptacle for receiving a fastening element, with which the overflow body is braced against the sink wall, is either formed in one piece with the sink wall or is arranged on a frame element which has an edge region running around the overflow opening, which is connected to the overflow opening adjacent visible surface of the sink wall.

In particular in the case of cast sinks, for example made of a plastic material, a ceramic material or a composite material, however, it is not readily possible to form the fastening element receptacle in one piece with a sink wall of the cast sink.

If a separate frame element is used, which rests against the visible surface of the sink wall, a dirty joint is created at the transition from the sink wall to the frame element, which is difficult to clean.

In other known overflow assemblies for sinks, it is provided that the overflow body is braced to the sink wall by means of a fastening element that remains visible to the user of the sink, without the fastening element being covered by a cover element.

Such solutions with a visible fastening element are visually unsatisfactory.

Most of the known designs of overflow assemblies for sinks must be completely dismantled in order to enable the overflow assembly to be cleaned.

There are also designs of overflow assemblies for sinks, which are tied to certain positions on the sink, for example to a position between two adjacent basins.

The present invention is based on the object of creating a sink of the type mentioned at the outset, in which a fastening element for bracing the overflow body against the sink wall is covered by a cover element and yet easy cleaning of the overflow assembly is possible and, in particular, no dirty joint between the sink wall, in which the overflow opening is arranged and a frame of the overflow assembly resting against the sink wall is created.

In a sink with the features of the preamble of claim 1, this object is achieved according to the invention in that the J Z positioning element on the sink wall is formed in one piece with the sink wall.

The solution according to the invention is based on the concept to form the at least one positioning element on the sink wall in one piece with the sink wall.

The sink wall is preferably designed in one piece with a base body of the sink.

The main body of the sink preferably comprises at least one basin of the sink.

In a preferred embodiment of the invention it is provided that the sink wall has at least two sink wall-side positioning elements and that the carrier element has at least two carrier-element-side positioning elements which interact with one of the sink wall-side positioning elements in such a way that the carrier element is secured against rotation relative to the sink wall.

In order to facilitate the assembly of the overflow assembly, it can also be provided that at least two carrier element-side positioning elements also serve as centering elements, by means of which the carrier element is centered relative to the overflow opening in the assembled state of the overflow assembly.

In particular, it can be provided that the centering elements each have a centering surface on the carrier element side, which interacts with a centering surface on the sink wall in order to center the carrier element relative to the overflow opening.

Furthermore, it can be provided that the sink wall has at least one contact element on the sink wall side and that the carrier element has at least one contact element on the carrier element side, which in the assembled state of the overflow assembly is in contact with the contact element on the sink wall side.

The at least one contact element on the sink wall is preferably designed in one piece with the sink wall.

It is particularly favorable if the sink wall has at least two contact elements on the sink wall and the carrier element has at least two contact elements on the carrier element which, when the overflow assembly is installed, bear against one of the contact elements on the sink wall, so that the carrier element covers the area of the overflow opening between the contact elements on the sink wall remains, bridged.

Such a carrier element thus represents a mounting bridge which makes it possible to arrange a fastening element receptacle in the area of the overflow opening without the need for a frame which rests against a visible surface of the sink wall adjacent to the overflow opening.

In a preferred embodiment of the invention, it is provided that a contact surface of at least one contact element on the sink wall is offset towards the overflow body with respect to a visible surface of the sink wall adjoining the overflow opening. This makes it possible for the carrier element to rest against the sink wall only in an area that is not visible to the user of the sink.

Furthermore, it can be provided that the carrier element has a form elasticity and is deformable during the assembly of the overflow assembly in such a way that in the assembled state of the overflow assembly at least one contact element on the carrier element rests essentially flat against a contact element on the sink wall.

This enables the carrier element to rest neatly on the contact element on the sink wall, regardless of any manufacturing tolerances in the manufacture of the carrier element.

In a particular embodiment of the invention, it is provided that the sink has a second overflow opening, on which preferably no contact element on the sink wall side is provided, the sink comprising a second overflow assembly which is arranged at the second overflow opening. The second overflow assembly preferably comprises a second carrier element, which can in particular be designed identically to the carrier element of the first overflow assembly, and a frame element which has a contact surface, with at least one carrier element-side contact element of the second carrier element, preferably essentially, in the assembled state of the second overflow assembly flat, rests against the contact surface of the frame element.

In this way, it is possible in particular to use identical carrier elements in both overflow assemblies of the sink, which reduces the number of different parts required overall for the construction of the sink due to the multiple use of similar parts. In a preferred embodiment of the invention it is further provided that, in the assembled state of the overflow assembly, no component of the carrier element protrudes beyond a visible surface of the sink wall adjoining the overflow opening.

It is particularly favorable if, in the assembled state of the overflow assembly, the cover element is completely received in the overflow opening. In this case, the cover element in particular does not protrude beyond a visible surface of the sink wall adjoining the overflow opening, for example in the interior of a basin, which is drained through the overflow opening.

In principle, the positioning elements on the carrier element side and the positioning elements on the sink wall side can be designed as desired, as long as they are designed such that they can interact to prevent the carrier element from rotating relative to the sink wall.

In principle, it must be provided according to the invention that at least one positioning element on the support element side comprises a recess and / or a groove and / or at least one positioning element on the sink wall side comprises a projection.

In an alternative embodiment of the invention, however, it is provided that at least one positioning element on the support element side comprises a projection and / or that at least one positioning element on the sink wall side comprises a recess and / or a groove.

According to the invention it is provided that the projection of the carrier element-side positioning element engages in the installed state of the overflow assembly in the recess and / or in the groove of the sink wall-side positioning element or the projection of the sink wall-side positioning element engages in the recess and / or groove of the carrier-side positioning element.

It can also be provided that a circumferential gap is formed between the cover element and a boundary surface of the overflow opening, through which water from a visible surface of the sink wall adjoining the overflow opening and / or from the interior of a basin of the sink adjoining the overflow opening, in particular a drip tray the sink, to which the overflow body can drain.

It is preferably provided that, in the assembled state of the overflow assembly, the cover element essentially completely covers a fastening element received at least partially in the fastening element receptacle of the carrier element.

Furthermore, it can be provided that the cover element has at least one cover element-side latching element which is latched to the carrier element in the assembled state of the overflow assembly.

In order to ensure that the cover element always assumes a desired angular orientation relative to the carrier element, it is advantageous if the cover element has at least one angular positioning element on the cover element side and the carrier element has at least one cover element angular positioning element which interacts with the angular positioning element on the cover element side in such a way that the cover element is secured against rotation relative to the carrier element.

As an alternative or in addition to this, it can also be provided that the overflow body has at least one overflow body-side angular positioning element which, when the overflow assembly is installed, interacts with an overflow body angular positioning element of the carrier element so that the overflow body is secured against rotation relative to the carrier element.

In particular, it can be provided that the overflow body angular positioning element of the carrier element is identical to a carrier element-side positioning element, so that the same component of the carrier element provides both anti-rotation protection in relation to the sink wall and rotation protection in relation to the overflow body.

When the carrier element is secured against rotation relative to the sink wall and at the same time the overflow body against rotation relative to the carrier element is secured, this offers the advantage that the overflow body is thus also secured against rotation relative to the sink wall.

The design of the overflow assembly and the overflow opening is basically suitable for use with a so-called vertical overflow, which is arranged on a side wall of a basin of the sink, which is oriented essentially vertically or inclined at a small acute angle to the vertical.

The inventive design of the overflow assembly, however, provides for use in a so-called horizontal overflow, which is arranged on a bottom wall of a draining basin of the sink, which is oriented essentially horizontally or inclined at a small acute angle to the horizontal.

Such a horizontal overflow is also referred to as drip part drainage if it is arranged on a draining basin of the sink.

The carrier element of the sink according to the invention is connected to the overflow body by means of the fastening element which is at least partially arranged in the fastening element receptacle of the carrier element. In particular, it can be provided that the carrier element and the overflow body are braced by means of the fastening element from two different sides against the sink wall in which the overflow opening is arranged.

In a special embodiment of the invention, the cover element is designed so that it can be brought into a position by pressing on the side and / or by pressing on an end region of the cover element, can in particular be pivoted into a position in which the cover element is partially detached from the carrier element, so that the cover element in this position can easily be gripped by a user of the sink and then completely detached from the carrier element.

In particular, it can be provided that the cover element can be brought into a position by pressing on the side and / or by pressing an end region of the cover element in which one or more locking elements on the cover element side are already unlatched from the respectively assigned locking elements on the carrier element side, while at least one other cover element-side Latching element is still in engagement with an associated latching element on the carrier element side.

If the carrier element is provided with a centering aid, a gap of uniform width is created between the cover element releasably held on the carrier element and a boundary wall of the overflow opening, which ensures a calm appearance.

A marking, for example in the form of lettering or a logo, can be attached to the cover element, which can be positioned with regard to its location and alignment by at least one angular positioning element on the cover element side, for example in the form of a notch, a groove or a hole, with at least one Cover element angular positioning element of the carrier element, for example a web, a guide pin or a projection, is brought into engagement.

The inventive design of the overflow assembly makes it possible to arrange the fastening element used to brace the overflow body against the sink wall, for example a fastening screw, on the sink so that it is invisible to the user of the sink.

The overflow assembly can be designed without a frame.

The overflow assembly according to the invention enables a material mix in which, for example, a component of the overflow assembly made of stainless steel, in particular a cover element comprising a stainless steel material, is used together with a sink made of a plastic material, a composite material or a ceramic material.

A rotation lock between the cover element and the carrier element makes it possible to always align a marking arranged on the cover element, for example lettering or a manufacturer's logo, in a desired orientation with respect to the base body of the sink.

The cover element of the overflow assembly is easily removable for cleaning purposes.

The overflow of the sink with the overflow opening according to the invention and the overflow assembly according to the invention is designed in an aesthetically pleasing manner.

In a preferred embodiment of the invention, it is provided that the cover element, in the assembled state of the overflow assembly, does not protrude beyond a visible surface of the sink wall adjoining the overflow assembly into the interior of a bowl of the sink.

In principle, however, it is possible with the sink according to the invention to coordinate the positioning elements and / or contact elements on the sink wall side and the positioning elements and / or contact elements on the carrier element side in such a way that the cover element, when the overflow assembly is installed, is flush, sub-flush or protruding with respect to the visible surface of the sink wall is.

In the sink according to the invention, the overflow opening is preferably designed in such a way that the base body of the sink with the overflow opening can be produced by a casting process without subsequent finishing. The geometry of the main body of the sink is therefore unrelated to the tool.

The overflow opening can be designed essentially circular or with any other cross-section, in particular with a rectangular cross-section.

Identical or functionally equivalent elements are denoted by the same reference symbols in all figures.

One in the Figures 1 to 16 The sink shown, denoted as a whole by 100, comprises a base body 102 with a main basin 104 and an additional basin 106, in particular a drip basin 108, arranged laterally next to the main basin 104.

The main basin 104 and the drip basin 108 represent areas 110 of the sink 100 to be drained.

A drain 114 arranged in a pool floor 112 serves to drain the main basin 104 (see FIG Fig. 2 ) and a vertical overflow 118 arranged in a side wall 116 of the main basin 104.

The overflow 118 is referred to as a vertical overflow because the sink wall 120 (side wall 116) on which the overflow 118 is arranged is oriented essentially vertically or inclined at a small acute angle with respect to the vertical.

The draining basin 108, which can be used, for example, to place items washed in the main basin 104, is drained via a horizontal overflow 122 which is arranged on a basin floor 124 of the draining basin 108.

The overflow 122 is referred to as a horizontal overflow because the sink wall 120 (basin floor 124) on which the overflow 122 is arranged is oriented essentially horizontally or inclined at a small acute angle with respect to the horizontal.

The structure of the horizontal overflow 122 is described below with reference to FIG Figures 4 to 11 explained in detail.

The horizontal overflow 122 comprises an overflow opening 126 in the sink wall 120 assigned to the overflow 122, which is surrounded by an area of the sink wall 120, the substantially flat upper side of which, facing the user of the sink 100, is hereinafter referred to as the visible surface 128 of the sink wall 120.

A boundary surface 130 of the overflow opening 126 is designed to be essentially rotationally symmetrical with respect to a central axis 132 of the horizontal overflow 122.

The boundary surface 130 comprises, as best from the sectional views of FIG Fig. 4 and 5 can be seen, an entry area 134 adjoining the visible surface 128 of the sink wall 120, preferably convexly curved, a central area adjoining the entry area 134 in an axial direction 136 of the horizontal overflow 122, which is aligned parallel to the central axis 132 of the horizontal overflow 122 138 and an end area 140 adjoining the central area 138 in the axial direction 136.

The central region 138 of the boundary surface 130 of the overflow opening 126 is essentially cylindrical.

The end region 140 of the delimiting surface 130 of the overflow opening 126 is preferably designed essentially in the shape of a truncated cone, so that the overflow opening 126 tapers towards its end facing away from the visible surface 128.

The end region 140 of the boundary surface 130 borders an overflow flange 142 of the sink wall 120, which protrudes from the sink wall 120 in the direction facing away from the visible surface 128.

How best to look Fig. 6 As can be seen, on opposite sections of the boundary surface 130 of the overflow opening 126, a contact element 144 on the sink wall protrudes from the boundary surface 130 in the direction of the central axis 132.

The top of each contact element 144 facing the visible surface 128 of the sink wall 120 forms a, preferably essentially flat, contact surface 146.

Each of the contact elements 144 is provided with a recess or groove 148 which extends in a longitudinal direction 150 of the horizontal overflow 122 and divides the respective contact element 144 into two sections 152a and 152b.

A groove bottom 154 of each groove 148 forms a centering surface 156 on the sink wall side which is inclined with respect to the axial direction 136.

The centering surface 156 can form a portion of the boundary surface 130 of the overflow opening 126, in particular a portion of the end region 140 of this boundary surface 130, or can be formed separately from the boundary surface 130 of the overflow opening 126.

Each of the grooves 148 forms a positioning element 158 on the sink wall.

The two grooves 148 are preferably aligned and designed in such a way that they are aligned with one another in a longitudinal direction 150 of the horizontal overflow 122.

The contact elements 144 on the sink wall side and the positioning elements 158 on the sink wall side are preferably formed in one piece with the sink wall 120.

The sink wall 120 is preferably formed in one piece with the base body 102 of the sink 100.

The base body 102 of the sink 100 can in particular be produced in a casting process and can be formed, for example, from a plastic material, a composite material or a ceramic material.

In addition to the overflow opening 126, the horizontal overflow 122 comprises an overflow assembly 160, the components of which are in particular in the Fig. 7 and 8th are shown.

The overflow assembly 160 comprises an overflow body 162, a sealing element 164, a carrier element 166, a fastening element 168 and a cover element 170.

In the assembled state of the overflow assembly 160, the overflow body 162 and the sealing element 164 are arranged on the rear side of the sink wall 120 facing away from the visible surface 128.

The carrier element 166, the fastening element 168 and the cover element 170 are arranged on the visible side of the sink wall 120 in the assembled state of the overflow assembly 160.

The overflow body 162 comprises a, for example, bowl-shaped water inlet chamber 172 with a water inlet opening 174, which is annularly surrounded by a contact flange 176 of the overflow body 162, and an overflow pipe 178, which opens into the water inlet chamber 172 on a side of the water inlet chamber 172 facing away from the water inlet opening 174 .

Furthermore, in the water inlet chamber 172 a, for example, essentially hollow cylindrical, receiving body 180 for (at least partially) receiving a threaded section 182 of the fastening element 168 is arranged, in which a threaded sleeve 181 with an internal thread (not shown) is arranged, which is complementary to the (also not shown) external thread of the threaded portion 182 of the fastening element 168 is formed.

The receiving body 180 is provided with slots 184 which run parallel to the axial direction 136 of the horizontal overflow 122 and which form angular positioning elements 185 on the overflow body.

The angular positioning elements 185 on the overflow body side are designed and aligned in such a way that they are aligned with one another along a longitudinal direction 187 of the overflow body 162.

The overflow body 162 is preferably made in one piece, for example from a suitable thermoplastically processable plastic material by an injection molding process.

The sealing element 164 is preferably formed from an elastic material, in particular from an elastomer material, and is designed in the shape of a ring.

The cross section of the sealing element 164 is preferably essentially constant in the longitudinal direction of the sealing element 164.

The sealing element 164 can, on its side facing the overflow body 162 in the mounted state of the overflow module 160 and / or on its side facing the overflow module 160 of an end face 186 of the overflow flange 142 on the sink wall 120 in the mounted state, each with one or more, for example three, Sealing lips 188 be provided (see in particular the Fig. 4 and 5 ).

As also best from the Fig. 4 and 5 As can be seen, in the assembled state of the overflow assembly 160, the sealing element 164 with the sealing lips 188 rests in a sealing manner on the end face 186 of the overflow flange 142 and, on the other hand, on a contact surface 190 of the contact flange 176 of the overflow body 162 opposite the end face 186 of the overflow flange 142.

Furthermore, in the assembled state of the overflow assembly 160, an outer jacket surface 192 of the sealing element 164 can rest against the inside of a lateral delimiting wall 194 of the contact flange 176 of the overflow body 162.

That in the Figures 9 to 11 Enlarged carrier element 166 of the overflow assembly 160 comprises a central, preferably essentially radially symmetrical, fastening element receptacle 196 with a receiving channel 198 running along the axial direction 136, through which the fastening element 168 can pass when the overflow assembly 160 is in the assembled state.

The fastening element 168 is designed, for example, as a fastening screw and, in addition to the already mentioned thread section 182, comprises a thread-free shaft section 200 adjoining the thread section 182 in the axial direction 136 and a head section 202 adjoining the thread-free shank section 200 in the axial direction 136.

The head section 202 can in particular be designed in such a way that it tapers conically towards the shaft section 200.

Furthermore, the head section 202 can be provided on its end face remote from the shaft section 200 with a polygonal recess 204, for example in the form of a hexagon socket.

The receiving channel 198 of the fastening element receptacle 196 of the carrier element 166 comprises a conical section 206 which, when the overflow assembly 160 is installed, receives the head section 202 of the fastening element 168, and a cylindrical section 208 which, when the overflow assembly 160 is installed, has the thread-free shaft section 200 and a part of the threaded portion 182 of the fastener 168 (see in particular Fig. 4 ).

From the fastening element receptacle 196 of the carrier element 166, two contact elements 212 extend in opposite directions from the fastening element receptacle 196 in a longitudinal direction 210 of the carrier element 166, which in the assembled state of the overflow assembly 160 corresponds to the longitudinal direction 150 of the horizontal overflow 122 and the overflow opening 126 path.

Each of the contact elements 212 ends at a, preferably widened, end region 214, the underside of which forms a, preferably substantially flat, contact surface 216 of the carrier element 166 (see FIG Fig. 10 ).

Furthermore, jumps in from each contact surface 216 of the carrier element 166 in an axial direction 218 of the carrier element 166, which is oriented perpendicular to the longitudinal direction 210 of the carrier element 166 and, in the assembled state of the overflow assembly 160, parallel to the axial direction 136 of the horizontal overflow 122 and the overflow opening 126 Positioning element 220 on the carrier element side.

The mutually facing inner edges 222 of the positioning element 220 on the support element side are spaced apart from one another in order to allow the fastening element 168 to pass through between these inner edges 222.

The outer edges 224 of the carrier element-side positioning elements 220 facing away from one another are inclined with respect to the axial direction 218, preferably at essentially the same angle at which the centering surfaces 156 of the overflow opening 126 are inclined with respect to the axial direction 136 of the horizontal overflow 122 and the overflow opening 126, and form centering surfaces 226 of the carrier element 166.

Frame element latching elements 227 are arranged on side surfaces 229 of the carrier element-side positioning elements 220, which connect the inner edges 222 and the outer edges 224 of the carrier element-side positioning elements 220 with one another, which have ramp surfaces 231 inclined at a small acute angle with respect to the axial direction 218 of the carrier element 166 ( please refer Fig. 10 ).

Free circumferential sections of the fastening element receptacle 196 of the carrier element 166 lying between the contact elements 212 of the carrier element 166 form carrier element-side locking elements 228 which can interact with the cover element-side locking elements 230 on the rear side of the cover element facing the carrier element 166 in the assembled state of the overflow assembly 160, in order to lock the cover element 170 to be releasably fixed on the carrier element 166.

Furthermore, on the upper side of each contact element 212 facing away from the respective contact surface 216, a respective cover element angular positioning element 232 is arranged, which protrudes from the respective contact surface 216 in the axial direction 218 of the carrier element 166 to the cover element 170 and, preferably from the fastening element receptacle 196 of the carrier element Starting from 166, extends in the longitudinal direction 210 of the carrier element 166.

Each of these cover element angular positioning elements 232 interacts with an associated angular positioning element 234 on the cover element side, which is arranged on the rear side of the cover element 170, facing the carrier element 166 when the overflow assembly 160 is installed, and has a, for example, notch-shaped recess 236, which has the respectively assigned cover element Angular positioning element 232 of the carrier element 166 receives when the cover element 170 is locked to the carrier element 166.

The carrier element 166 is preferably formed in one piece.

The carrier element 166 can in particular be designed as an injection-molded part.

The carrier element 166 preferably comprises a plastic material, in particular a polyamide material, which is preferably reinforced with glass fibers.

The angular positioning elements 234 on the cover element side and the latching elements 230 on the cover element side of the cover element 170 are preferably arranged on a base body 238 of the cover element 170 and are preferably formed in one piece with the base body 238.

The base body 238 can in particular be designed as an injection molded part.

The base body 238 preferably comprises a suitable plastic material, for example a polyamide material, which is preferably reinforced with glass fibers.

The base body 238 of the cover element 170 comprises a, preferably essentially circular disk-shaped, base plate 240, from which the cover element-side locking elements 230 and the cover-element-side angular positioning elements 234 protrude in the axial direction 218 towards the carrier element 166.

The visible side of the cover element 170 facing away from the carrier element 166 is preferably formed by a cover plate 242, which is fixed to the base body 238 in a form-fitting manner, for example by flanging.

As an alternative or in addition to this, it can also be provided that the cover plate 242 is fixed to the base body 238 by a material bond, in particular by gluing, and / or by a force fit, in particular by a press fit.

The cover plate 242 preferably comprises a material different from the material of the base body 238.

In particular, it can be provided that the cover plate 242 comprises a metallic material, in particular a stainless steel material, preferably is formed essentially completely from a metallic material, in particular from a stainless steel material.

The cover plate 242 is preferably designed to be essentially rotationally symmetrical (with respect to the central axis 132).

On its visible side 244 facing away from the carrier element 166 in the assembled state of the overflow assembly 160, the cover plate 242 is preferably provided with a non-rotationally symmetrical marking 246, which extends in a longitudinal direction 248 of the cover element 170.

Such a marking 246 can be embodied, for example, as lettering, in particular as a manufacturer's logo.

The marking 246 is preferably only produced after the cover plate 242 has been installed on the base body 238, for example by laser inscription, in order to ensure that the alignment of the marking corresponds exactly to the longitudinal direction 248 of the cover element 170 specified by the angular positioning elements 234 on the cover element.

The recess 236 of the angular positioning elements 234 on the cover element side are arranged and aligned in such a way that they are aligned with one another in the longitudinal direction 248 of the cover element 170.

The carrier element 166 is preferably formed from an elastically deformable material, so that the carrier element 166 has a form elasticity.

In an in Fig. 11 shown relaxed initial state of the carrier element 166 before the assembly of the overflow assembly 160, in which the carrier element 166 is produced, for example in an injection molding process, the contact surfaces 216 of the carrier element 166 are, preferably concave, curved.

During the assembly of the overflow assembly 160, the carrier element 166 is deformed by the tightening of the fastening element 168 against the fastening element receptacle 196 of the carrier element 166 in such a way that the curvature of the contact surfaces 216 is essentially eliminated and, in the assembled state of the overflow body 162, the then essentially flat contact surfaces 216 abut essentially flat against the contact surfaces 146 of the contact elements 144 on the sink wall.

In the assembled state of the overflow assembly, the carrier element 166 is thus under an elastic pretension.

When assembling the above-described overflow assembly 160 on the overflow opening 126 of the horizontal overflow 122, the procedure is as follows:
The sealing element 164 is placed on the contact flange 176 of the overflow body 162.

The overflow body 162 with the sealing element 164 is positioned on the rear side of the sink wall 120 such that the central axis of the overflow body 162 running through the receiving body 180 of the overflow body 162 coincides with the central axis 132 of the overflow opening 126.

The carrier element 166 is inserted into the overflow opening 126 in such a way that the carrier element-side positioning elements 220 engage in the grooves 148 of the sink wall-side contact elements 144, which serve as sink wall-side positioning elements 158.

In doing so, the carrier element 166 is pushed into the overflow opening 126 until the opposing centering surfaces 226 of the carrier element 166, preferably essentially flat, abut the centering surfaces 156 on the sink wall.

This ensures that the carrier element 166 is centered relative to the overflow opening 126, so that the central axis of the carrier element 166 running through the fastening element receptacle 196 coincides with the central axis 132 of the overflow opening 126.

When the carrier element 166 is inserted into the overflow opening 126, lower end regions of the carrier element-side positioning elements 220 also come into engagement with the slots 184 of the receiving body 180 of the overflow body 162, which serve as overflow-body-side angular positioning elements 185.

This ensures that the longitudinal direction 187 of the overflow element 162 corresponds to the longitudinal direction 210 of the carrier element 166 and the overflow element 162 is secured against rotation relative to the carrier element 166 about the central axis 132.

The carrier element-side positioning elements 220 thus simultaneously serve as overflow body angular positioning elements 250, which interact with the overflow body-side angular positioning elements 185 in order to prevent rotation of the overflow body 162 relative to the carrier element 166.

Since the carrier element 166 is prevented from rotating relative to the sink wall 120 by the interaction of the carrier element-side positioning elements 220 with the sink wall-side positioning elements 158, the overflow body 162 is thus also secured from rotating relative to the sink wall 120.

The fastening element 168 is inserted into the fastening element receptacle 196 of the carrier element 166.

By screwing the external thread of the fastening element 168 into the internal thread of the threaded sleeve 181 of the receiving body 180 of the overflow body 162, the carrier element 166, the overflow body 162 and the sealing element 164 are braced against the sink wall 120.

The carrier element 166 goes from the in Fig. 11 The relaxed initial state shown changes over to the tensioned, assembled state, in which the contact surfaces 216 of the contact elements 212 of the carrier element 166 are essentially flat and, preferably essentially flat, bear against the contact surfaces 146 of the sink wall-side contact elements 144.

After the mounting of the carrier element 166 on the sink wall 120 has been completed, the cover element 170 is releasably attached to the carrier element 166 by sliding the cover element 170 with the locking elements 230 on the cover element first in the axial direction 136 onto the fastening element receptacle 196 of the carrier element 166, the Latching elements 230 on the cover element side, which are elastically deformable, are moved away from the central axis 132 until the free ends of the latching elements 230 on the cover element side engage behind the peripheral sections of the fastening element receptacle 196 of the carrier element 166, which serve as latching elements 228 on the carrier element side, and the cover element 170 latches with the carrier element 166 is.

This latching state can only be achieved if the angular positioning elements 234 on the cover element side match the respective assigned cover element angular positioning elements 232 of the carrier element 166 in terms of their angular position in relation to the central axis 132, so that the cover element angular positioning elements 232 of the carrier element 166 in the recesses 236 of the cover element side Angular positioning elements 234 can intervene.

This ensures that in the assembled state of the cover element 170, the longitudinal direction 248 of the cover element 170 corresponds to the longitudinal direction 210 of the carrier element 166.

Since, for the reasons already explained above, the longitudinal direction 210 of the carrier element 166 in the assembled state of the overflow assembly 160 is aligned parallel to the longitudinal direction 150 of the overflow opening 126 and parallel to the longitudinal direction 187 of the overflow body 162, the marking 246 is always parallel to the overflow assembly 160 in the assembled state Aligned in the longitudinal direction 187 of the overflow body 162, so that the correct alignment of the overflow body 162 relative to the sink wall 120 can be checked by means of the marking 246 on the cover element 170.

After the overflow assembly 160 has been installed on the overflow opening of the horizontal overflow 122, water can preferably flow out of the drip basin 108 through a remaining between the peripheral wall of the cover element 170 and the boundary surface 130 of the overflow opening 126 annular gap 252 encircling the cover element 170 (see in particular the Fig. 4 and 5 ) from an interior 254 of the drip basin 108 to the water inlet opening 174 of the overflow body 162 and from there through the overflow pipe 178 to a drain pipe (not shown) connected to a lower end of the overflow pipe 178.

Since the contact surfaces 146 of the sink wall-side contact elements 144 are offset from the visible surface 128 of the sink wall 120 in the axial direction 136 towards the overflow body 162, the cover element 170 is completely received in the overflow opening 126 when the overflow assembly 160 is installed, so that it is not part of the cover element 170 and no other component of the overflow assembly 160 protrudes beyond the visible surface 128 of the sink wall 120 into the interior 254 of the drip basin 108.

The structure of the vertical overflow 118 of the sink 100, which is arranged on the side wall 116 of the main basin 104, is described below with reference to FIG Figures 12 to 16 explained.

How best to look Fig. 13 As can be seen, the overflow opening 256 of the vertical overflow 118 is designed as an essentially cylindrical passage opening 258 in the associated sink wall 120 (side wall 116) and has an essentially cylindrical delimiting surface 260.

In addition to the overflow opening 256, the vertical overflow 118 includes one in particular in the Fig. 13 and 14th illustrated overflow assembly 262.

The overflow assembly 262 comprises an overflow body 264, a sealing element 266, a frame element 268, a carrier element 166, which is preferably constructed identically to the carrier element 166 of the horizontal overflow 122, a fastening element 168 and a cover element 170, which is preferably constructed identically to the cover element 170 of the horizontal overflow 122.

The structure of the overflow body 264 of the vertical overflow 118 essentially corresponds to the structure of the overflow body 162 of the horizontal overflow 122, with the water inlet opening 174 and the water inlet chamber 172 in the overflow body 264 of the vertical overflow 118 preferably essentially rotationally symmetrical to the central axis 132 of the overflow and the overflow opening 264 are formed and wherein the overflow pipe 178 opens into the water inlet chamber 172 preferably in a direction perpendicular to the central axis 132.

The sealing element 266 can be designed as a simple sealing ring without sealing lips 188.

The frame element 268 is required for the vertical overflow 118 in order to be able to position the carrier element 166 at the overflow opening 256, which does not have any contact elements 144 on the sink wall projecting into the interior of the overflow opening 256.

The frame element 268 comprises an essentially cylindrical circumferential wall 270, from the edge of which an annular abutment collar 272 protrudes outward in the radial direction.

An annular collar 274 projects radially inward from an edge of the circumferential wall 270 opposite the contact collar 272.

Two diametrically opposite points of the annular collar 174 are connected to one another by a web 276.

The web 276 is provided with a slot 278 which has a central section 280 for the passage of the fastening element receptacle 196 of the Support element 166 through the web 276 and two lateral sections 282 extending away from the central section 280 in a radial longitudinal direction 284 of the frame element 268 for the passage of a respective support element-side positioning element 220 of the support element 166.

A front side of the web 276 and of the annular collar 274 facing the carrier element 166 forms a contact surface 283 of the frame element 268.

The assembly of the overflow assembly 262 of the vertical overflow 118 on the overflow opening 256 is as follows:
The sealing element 266 is inserted into the contact flange 176 of the overflow body 264.

The overflow body 264 with the sealing element 266 is positioned on the rear side of the sink wall 120 in such a way that the central axis of the overflow body 264 running through the receiving body 180 coincides with the central axis 232 of the overflow opening 256.

The carrier element 166 is pushed with the carrier element-side positioning elements 220 first into the slot 278 in the web 276 of the frame element 268, the regions of the web 276 delimiting the slot 278 being slightly bent up during the movement along the ramp surfaces 231, until the web 276 the frame element- Latching elements 227 engages behind on the side surfaces 229 of the positioning elements 220 on the carrier element side, and thus the carrier element 166 is locked to the frame element 268 to form a jointly manageable unit.

The engagement of the carrier element-side positioning elements 220 in the lateral sections 282 of the slot 278 in the web 276 of the frame element 268 ensures that the longitudinal direction 284 of the frame element 268 coincides with the longitudinal direction 210 of the carrier element 166 and that Frame element 268 is secured against rotation relative to the carrier element 166. The lateral sections 282 of the slot 278 thus serve as positioning elements 281 on the frame element side.

The carrier element 166 and the frame element 268 are inserted into the overflow opening 256 until the frame element 268 with its contact collar 272 rests, preferably essentially flat, on the visible surface 128 of the sink wall 120 surrounding the overflow opening 256.

This is only possible if the positioning elements 220 on the carrier element side engage in the slots 184 in the receiving body 180 of the overflow body 264, which serve as angular positioning elements 185 on the overflow body side.

Also in the case of the vertical overflow 118, the end regions of the carrier element-side positioning elements 220 serve as overflow body angular positioning elements 250, which interact with the overflow body-side angular positioning elements 185 in such a way that it is ensured that the longitudinal direction 187 of the overflow body 187, which runs through the two slots 184 of the receiving body 180, coincides with the longitudinal direction 210 of the carrier element 166 and the overflow body 264 is secured against rotation relative to the carrier element 166.

The fastening element 168 is inserted into the fastening element receptacle 196 of the carrier element 166 and screwed with the external thread of its threaded section 182 into the internal thread of the threaded sleeve 181 of the receiving body 180 of the overflow body 264 until the carrier element 166 comes out of its Fig. 11 The relaxed initial state shown is transferred to its assembled state, in which the contact surfaces 216 of the contact elements 212 of the carrier element 166 are essentially flat and, preferably essentially flat, bear against the contact surface 283 of the annular collar 274 and the web 276 of the frame element 268.

In this state, the overflow body 264, the sealing element 266, the frame element 268 and the carrier element 166 are braced against the sink wall 120 by the fastening element 168.

Finally, the cover element 170 is releasably connected to the carrier element 166 by latching in the same way as with the horizontal overflow 122.

One in the Figures 17 to 28 The illustrated second embodiment of a sink 100 differs from that in FIGS Figures 1 to 16 The first embodiment illustrated essentially by the design of the vertical overflow 118 and the horizontal overflow 122.

The overflow opening 126 of the horizontal overflow 122 differs from the overflow opening 126 of the first embodiment essentially in that the boundary surface 130 of the overflow opening 126 is not rotationally symmetrical, but has an essentially rectangular circumferential contour with rounded corner areas (see FIG Fig. 22 ).

The overflow opening 126 of the horizontal overflow 122 is also provided in this second embodiment with contact elements 144 protruding towards the central axis 132 and with positioning elements 158 on the sink wall side in the form of grooves 148.

The carrier element 166 of the overflow assembly 160 of the horizontal overflow 122 differs in this embodiment from the carrier element 166 of the first embodiment essentially in that the carrier element-side latching elements 228 are not designed as peripheral sections of the fastening element receptacle 196, but as several, for example four, latching projections 286, which are preferably arranged on side surfaces 188 of the contact elements 112 of the carrier element 166 and in the In the assembled state of the overflow assembly 160, the locking elements 230 on the cover element side engage from behind.

In order to avoid bending of the carrier element 166, support elements 188 are also provided on the carrier element 166, which are supported by the fastening element receptacle 196, for example in a transverse direction 290 of the carrier element 166, which is oriented perpendicular to the longitudinal direction 210 and to the axial direction 218 of the carrier element 166 stick out.

In the assembled state of the overflow assembly 160, the end faces 290 of these support elements 288 facing away from the fastening element receptacle 196 lie against the boundary surface 130 of the overflow opening 126, preferably essentially flat (see FIG Fig. 20 ), as a result of which the central section of the carrier element 166 is prevented from bending in the axial direction 218 towards the overflow body 162 under the action of the tensioning force generated by the fastening element 168.

The end regions 214 of the contact elements 212 of the carrier element 166 facing away from the fastening element receptacle 196 can be provided with a bevel 292 in this embodiment.

In this embodiment of the horizontal overflow 122, the cover element 170 is likewise not rotationally symmetrical, but essentially rectangular, for adaptation to the overflow opening 126, which is essentially rectangular in cross section.

The cover element 170 can in particular be formed in one piece.

In this embodiment, the cover element 170 is preferably formed as a whole from a metallic material, in particular from a stainless steel material.

In this embodiment of the cover element 170, the locking elements 230 on the cover element side are preferably formed in one piece with the cover plate 242 and are arranged on the circumference of the cover element 170 corresponding to the positions of the locking projections 286 of the carrier element 166 (see FIG Fig. 23 ).

When the cover element 170 is latched to the carrier element 166, by exerting pressure on an end area 302 of the cover element, which is arranged between two locking elements 230 on the cover element side and a narrow side of the outer edge of the cover plate 242, the cover element 170 can be moved around one through the two end areas 302 adjacent cover element-side locking elements 230 are pivoted into a position in which the cover element-side locking elements 230 further away from the end area 302 are unlatched from the associated carrier element-side locking elements 228 and the cover element 170 is easily gripped by a user of the sink 100 and completely from the carrier element 166 can be solved.

In this second embodiment of the horizontal overflow 122, the overflow body 162, the sealing element 164 and the fastening element 168 can be designed in the same way as in the first embodiment described above.

Incidentally, this is particularly true in the Figures 20 to 24 The illustrated second embodiment of a horizontal overflow 122 in terms of structure, function and method of manufacture with the particular in FIGS Figures 4 to 11 first embodiment shown, reference is made to the above description in this respect.

The one in the Figures 25 to 28 The illustrated vertical overflow 118 of the second embodiment of a sink 100 differs from the vertical overflow 118 in the first embodiment of the sink 100 essentially in that That the carrier element 166 is omitted and instead a modified frame element 294 is used, which instead of a web 276 with a slot 278 for receiving a carrier element 166 has two fastening element receptacles 196, which, preferably in one piece, with an overflow opening 256 around the, for example, rectangular in this case circumferential frame part 298 are connected.

Furthermore, the frame part 298 of the frame element 294 is provided with several, for example four, latching elements 300 on the frame element side, which interact with the respective associated cover element-side latching elements 230 in order to detachably fix the cover element 170 by latching on the frame element 294.

In this embodiment, the overflow body 264 is provided with two receiving bodies 180 for two fastening elements 168, for example in the form of fastening screws.

Since the two fastening elements 168 each penetrate a fastening element receptacle 296 on the frame element 294 and, when the overflow assembly 262 is installed, are screwed into an internal thread of the threaded sleeve 181 of the respectively associated receiving body 180, this already ensures that the longitudinal direction 187 of the overflow body 264 coincides with the longitudinal direction 284 of the frame element 294 and thus also coincides with the longitudinal direction 248 of the cover element 170, without it being necessary to provide angular positioning elements 185 on the overflow body side or angular positioning elements 234 on the cover element side for this purpose.

The procedure for installing the overflow assembly 262 on the overflow opening 256 of the vertical overflow 118 of the second embodiment of a sink 100 is as follows:
The sealing element 266 is inserted into the contact flange 176 of the overflow body 264, and the overflow body 264 is arranged together with the sealing element 266 on the back of the sink wall 120 surrounding the overflow opening 256 that the receiving body 180 of the overflow body 264 in the axial direction 136 with the fastening element receptacles 296 of the frame element 294 are aligned when the frame element 294 is inserted into the overflow opening 256.

The fastening elements 168 are inserted into the fastening element receptacles 296 of the frame element 294 and their external threads are screwed into the internal threads of the threaded sleeves 181 of the receiving bodies 180 of the overflow body 264 until the overflow body 264, the sealing element 266 and the frame element 294 through the fastening elements 168 against the sink wall 120 are tense.

Finally, the cover element 170 is placed on the frame element 294 and locked to the same.

Incidentally, it is correct in the Figures 17 to 28 The illustrated second embodiment of a sink 100 in terms of structure, function and method of manufacture with the one shown in FIG Figures 1 to 16 first embodiment shown, reference is made to the above description in this respect.
