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

If a separate frame element is used, which rests against the visible surface of the pelvic floor, the result is a dirt joint at the transition from the pelvic floor to the frame element, which is difficult to clean.

In other known drain assemblies for sinks is provided that the drain body is clamped by means of a visible to the user of the sink fastener with the pelvic floor, without the fastener is covered by a cover.

Such solutions with visible remaining fastener are visually unsatisfactory.

Most known designs of sinks for sinks must be completely disassembled to allow cleaning of the drain assembly.

There are also designs of drain assemblies for sinks that are bonded to specific locations on the sink, for example to a position between two adjacent pools.

The present invention has for its object to provide a sink of the type mentioned, in which a fastener for clamping the drain body is covered against the pelvic floor by a cover and yet easy cleaning of the drain assembly is possible and in particular no dirt joint between the pelvic floor, in which the drain opening is arranged, and a voltage applied to the bottom of the pool frame of the drain assembly is formed.

This object is achieved by a sink according to claim 1.

The inventive solution is based on the concept, the pelvic floor in the drain opening by the provision of at least one bottom side positioning element designed so that a support member to which the cover is releasably held in the mounted state of the drain assembly by means of a carrier element-side positioning anti-rotation on the pelvic floor positionable is, so that can be dispensed with a circulating around the drain opening frame.

The at least one bottom side positioning element is integrally formed with the pelvic floor.

In a preferred embodiment of the invention it is provided that the pelvic floor has at least two bottom side positioning elements and that the support element has at least two carrier element-side positioning, which cooperate with each one of the bottom side positioning elements, that the support member is secured against rotation relative to the pelvic floor.

In order to facilitate the assembly of the drain assembly, it may further be provided that at least two carrier element-side positioning serve at the same time as centering elements, through which the carrier element is centered in the mounted state of the drain assembly relative to the drain opening.

In this case, it can be provided, in particular, that the centering elements each have a carrier element-side centering surface, which cooperates with a bottom side centering surface to cause the centering of the support member relative to the drain opening.

Furthermore, it can be provided that the pelvic floor has at least one pelvic floor-side abutment element and that the support element has at least one support element-side abutment element, which rests in the mounted state of the drain assembly on the basin floor side contact element.

The at least one basin-bottom contact element is preferably formed integrally with the pelvic floor.

It is particularly expedient for the pelvic floor to have at least two abutment bottom-side abutment elements and for the abutment element to have at least two abutment element-side abutment elements which, in the assembled state of the abutment assembly, abut one of the abutment bottom-side abutment elements, so that the abutment element defines the region of the drainage opening between the abutment bottom-side abutment elements remains, bridged.

Such a carrier element thus represents a mounting bridge, which makes it possible to arrange a fastener receptacle in the region of the drain opening, without the need for a frame is required, which rests against an adjacent to the drain opening visible surface of the pelvic floor.

In a preferred embodiment of the invention, it is provided that a bearing surface of at least one basin-side contact element is offset from the drain body toward a visible surface of the pelvic floor adjacent to the drain opening. This makes it possible that the carrier element rests against the pelvic floor only in an area not visible to the user of the sink.

Furthermore, it can be provided that the carrier element has a formula elasticity and is deformable during assembly of the drain assembly such that in the assembled state of the drain assembly at least one carrier element-side application element is substantially flat against a basin floor side contact element.

In this way, a clean concern of the support element on the basin floor side contact element is made possible regardless of any manufacturing tolerances in the production of the support element.

In a particular embodiment of the invention it is provided that the sink has an overflow opening, on which preferably no flush-wall-side contact element is provided, wherein the sink comprises an overflow assembly, which is arranged at the overflow opening. In this case, the overflow assembly preferably comprises a second support member, which may be formed in particular identical to the support member of the drain assembly, and a frame member having a contact surface, wherein in the assembled state of the overflow assembly at least one carrier element-side contact element of the second support member, preferably substantially flat abuts the contact surface of the frame member.

In this way, it is particularly possible to use identically designed support elements in the overflow assembly and in the drain assembly of the sink, which reduces the number of parts required for the construction of the sink as a whole by the multiple use of similar parts.

In a preferred embodiment of the invention, it is further provided that in the mounted state of the drain assembly, no component of the support element projects beyond a visible surface of the pelvic floor adjoining the drain opening.

It is particularly favorable if, in the mounted state of the drain assembly, the cover element is substantially completely received in the drain opening. In this case, in particular, the covering element does not project beyond a visible surface of the pelvic floor adjoining the discharge opening, for example into the interior of a basin, which is dewatered through the drainage opening.

The carrier element-side positioning and the bottom-side positioning elements are designed so that they can cooperate to prevent rotation of the support member relative to the pelvic floor.

In one embodiment of the invention, it is provided that at least one carrier element-side positioning element comprises a recess and / or a groove and / or at least one bottom side positioning element comprises a projection.

In another embodiment of the invention, it is provided that at least one carrier element-side positioning element comprises a projection and / or that at least one bottom side positioning element comprises a recess and / or a groove.

It is preferably provided that the projection of the carrier element-side positioning in the assembled state of the drain assembly engages in the recess and / or in the groove of the bottom side positioning element.

Furthermore, it can be provided that a circumferential gap is formed between the cover element and a boundary surface of the drain opening, through which water from a visible surface adjacent to the drain opening of the pelvic floor and / or from the interior of a adjacent to the drain opening basin of the sink, in particular a drip tray the sink, can drain to the drain body.

It is preferably provided that in the assembled state of the drain assembly, the cover substantially completely covers a at least partially received in the fastener receiving element of the support element fastener.

Furthermore, it can be provided that the cover has at least one cover element-side locking element which is locked in the mounted state of the drain assembly with the support member.

To achieve that the cover always assumes a desired angular orientation relative to the support element, it is advantageous if the cover has at least one cover element side Winkelpositionierelement and the support member has at least one Abdeckelement Winkelpositionierelement, which cooperates with the cover element side Winkelpositionierelement that the cover is secured against rotation relative to the support element.

Alternatively or additionally, it can also be provided that the drain body has at least one outlet-side Winkelpositionierelement which cooperates in the assembled state of the drain assembly with a drain body Winkelpositionierelement of the support member, that the drain body is secured against rotation relative to the support member.

In particular, it may be provided that the drain body Winkelpositionierelement the support element is identical to a carrier element-side positioning, so that the same component of the support member causes both a rotation with respect to the pelvic floor and a rotation with respect to the drain body.

If the support member is secured against rotation relative to the pelvic floor and at the same time the drain body is secured against rotation relative to the support member, this has the advantage that thus the drain body is secured against rotation relative to the pelvic floor.

The design of the drain assembly according to the invention is particularly suitable for use in a so-called horizontal drain, which is arranged on a bottom wall of a sink of the sink, in particular a drain bowl of the sink, which is oriented substantially horizontally or inclined at a slight acute angle to the horizontal ,

Such a horizontal overflow is also referred to as drip tray drainage when it is placed on a drainer of the sink.

The carrier element of the sink according to the invention is connected to the drain body by means of the fastening element, which is arranged at least partially in the fastening element receptacle of the carrier element.

In particular, it can be provided that the carrier element and the drain body are clamped by means of the fastening element of two different sides against the pelvic floor, in which the drain opening is arranged.

In a particular embodiment of the invention, the cover is designed so that it can be brought by lateral pressing and / or by pressing on an end portion of the cover in a position, in particular in a position can be pivoted, in which the cover partially from the support element is solved, so that the cover member can be easily grasped in this position by a user of the sink and then completely detached from the support element.

In particular, it can be provided that the cover can be brought by lateral pressing and / or by pressing on an end portion of the cover in a position in which one or more cover element-side locking elements already from the respectively associated carrier element-side locking elements are unlocked, while at least one other covering element-side locking element is still engaged with an associated carrier element-side locking element.

If the carrier element is provided with a centering, a uniform width circumferential gap between the releasably held on the support member cover and a boundary wall of the drain opening is generated, which ensures a calm optics.

A marking, for example in the form of a lettering or a logo, can be attached to the cover element, which can be positioned with respect to its position and orientation by having at least one cover element-side angular positioning element, for example in the form of a notch, a groove or a bore, with at least one Cover element Winkelpositionierelement the support member, for example, a web, a guide pin or a projection, is brought into engagement.

The embodiment of the drain assembly according to the invention makes it possible to arrange the fastening element used for clamping the drain body against the pool bottom, for example a fastening screw, invisibly to the sink of the user of the sink.

The drain assembly may be frameless.

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

An anti-rotation between the cover and the support member makes it possible to align a arranged on the cover label, such as a lettering or a manufacturer's logo, always in a desired orientation with respect to the main body of the sink.

The cover member of the drain assembly is easily removable for cleaning purposes.

The opposite outer edges 224 of the carrier element side positioning members 220 are inclined with respect to the axial direction 218, and preferably at substantially the same angle at which the centering surfaces 156 of the drain opening 126 are inclined relative to the axial direction 136 of the drain 122 and the drain opening 126, and form Centering surfaces 226 of the support member 166th

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, frame element locking elements 227 are arranged which have ramp surfaces 231 inclined at a slight acute angle relative to the axial direction 218 of the carrier element 16 ( please refer Fig. 10 ).

Between the contact elements 212 of the support member 166 lying free peripheral portions of the fastener element receptacle 196 of the support member 166 form carrier element-side locking elements 228 which can cooperate with cover element-side locking elements 230 on the support member 166 in the assembled state of the drain assembly 160 rear side of the cover member to the cover member 170 by latching releasably attach to the support member 166.

Furthermore, a covering element Winkelpositionierelement 232 is disposed on the respective contact surface 216 facing away from each top of Anlegeelements 212, which protrudes from the respective contact surface 216 in the axial direction 218 of the support member 166 to the cover member 170 and, preferably from the fastener element receptacle 196 of the support member 166, extending in the longitudinal direction 210 of the support member 166.

Each of these cover element Winkelpositionierelemente 232 cooperates with each associated cover element side Winkelpositionierelement 234, which is arranged on the support member 166 in the mounted state of the drain assembly 160 rear side of the cover 170 and a, for example notched, recess 236, which has the respective associated cover -Winkelpositionierelement 232 of the support member 166 receives when the cover member 170 is locked to the support member 166.

The carrier element 166 is preferably formed in one piece.

The support member 166 may be formed in particular 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 cover element-side angle positioning elements 234 and the cover element-side latching elements 230 of the cover element 170 are preferably arranged on a base body 238 of the cover element 170 and preferably formed integrally with the base body 238.

The base body 238 may be formed in particular 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 substantially annular disc-shaped, base plate 240, from which the covering element-side latching elements 230 and the cover element-side angle positioning elements 234 project in the axial direction 218 toward 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, for example by beading, is fixed in a form-fitting manner to the base body 238.

Alternatively or additionally, it can also be provided that the cover plate 242 is fixed to the base body 238 by adhesion, in particular by adhesive bonding, and / or by adhesion, in particular by interference fit.

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

In particular, it may be provided that the cover plate 242 comprises a metallic material, in particular a stainless steel material, preferably substantially completely made of a metallic material, in particular of a stainless steel material.

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

At its side facing away from the support member 166 visible side 244 in the mounted state of the drain assembly 160, the cover plate 242 is preferably provided with a non-rotationally symmetric marking 246 which extends in a longitudinal direction 248 of the cover 170.

Such a marking 246 may be formed, for example, as a lettering, in particular as a logo of the manufacturer.

Preferably, the marking 246 is generated only after the mounting of the cover plate 242 on the base body 238, for example by laser inscription, to ensure that the alignment of the mark exactly matches the predetermined by the cover element side Winkelpositionierelemente 234 longitudinal direction 248 of the cover 170.

The recess 236 of the cover member side Winkelpositionierelemente 234 are arranged and aligned so that they are aligned in the longitudinal direction 248 of the cover 170 with each other.

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

In an in Fig. 11 illustrated relaxed initial state of the support member 166 prior to assembly of the drain assembly 160, in which the support member 166, for example, in an injection molding, is prepared, the contact surfaces 216 of the support member 166, preferably concave, curved.

When mounting the drain assembly 160, the support member 166 is deformed by the tightening of the fastener 168 against the fastener receiving portion 196 of the support member 166 so that the curvature of the contact surfaces 216 is substantially canceled and in the mounted state of the drain body 162, the then substantially flat contact surfaces 216 lie substantially flat against the contact surfaces 146 of the basin bottom side abutment elements 144.

In the mounted state of the drain assembly, the support member 166 is thus under a resilient bias.

When mounting the drain assembly 160 described above at the drain opening 126 of the drain 122, the procedure is as follows:
The sealing element 164 is inserted on the abutment flange 176 of the drain body 162.

The drain body 162 with the sealing element 164 is positioned on the rear side of the pelvic floor 124 in such a way that the center axis of the drain body 162 passing through the receiving body 180 of the drain body 162 coincides with the center axis 132 of the drain opening 126.

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

In this case, the support member 166 is inserted into the drain opening 126 until the opposing centering surfaces 226 of the support member 166, preferably substantially flat, abut the bottom surface 156 on the bottom surface.

In this way, it is achieved that the carrier element 166 is centered relative to the drain opening 126, so that the central axis of the carrier element 166 extending through the fastening element receiver 196 coincides with the central axis 132 of the drain opening 126.

When inserting the carrier element 166 into the drain opening 126, further lower end regions of the carrier element-side positioning elements 220 come into engagement with the slots 184 of the receiving body 180 of the drain body 162, which serve as outlet body-side angle positioning elements 185.

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

The carrier element-side positioning elements 220 thus serve at the same time as drain body angle positioning elements 250, which cooperate with the drain body side angle positioning elements 185 in order to prevent a rotation of the drain body 162 relative to the carrier element 166.

Since the support member 166 is prevented by the interaction of the carrier member side positioning 220 with the bottom side positioning elements 158 at a rotation relative to the pelvic floor 124, thus the drain body 162 is also secured to a rotation relative to the pelvic floor 124.

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 in the internal thread of the threaded sleeve 181 of the receiving body 180 of the drain body 162, the support member 166, the drain body 162 and the sealing element 164 are braced against the pelvic floor 124.

In this case, the carrier element 166 of the in Fig. 11 illustrated relaxed initial state in the clamped mounted state over, in which the contact surfaces 216 of the contact elements 212 of the support member 166 are substantially flat and, preferably substantially flat, abut against the abutment surfaces 146 of the bottom side abutment elements 144.

After the assembly of the support member 166 is completed on the pelvic floor 124, the cover 170 is releasably secured to the support member 166 by the cover 170 is pushed with the cover element side locking elements 230 in the axial direction 136 on the fastener receiving element 196 of the support member 166 first, the cover element-side locking elements 230 which are elastically deformable, are moved away from the central axis 132 until the free ends of the cover element-side locking elements 230 engage behind the peripheral portions of the fastener element receptacle 196 of the support member 166, which serve as carrier element-side locking elements 228 and the cover member 170 is locked to the support member 166 is.

This locking state can only be achieved if the cover element-side Winkelpositionierelemente 234 in terms of their angular position with respect to the central axis 132 with the respective associated Abdeckelement Winkelpositionierelementen 232 of the support member 166 match, so that the Abdeckelement Winkelpositionierelemente 232 of the support member 166 in the recesses 236 of the cover element side Angle positioning elements 234 can engage.

This ensures that in the monited state of the cover 170, the longitudinal direction 248 of the cover 170 coincides with the longitudinal direction 210 of the support member 166.

Since, for the reasons already explained above, the longitudinal direction 210 of the support element 166 is aligned parallel to the longitudinal direction 150 of the drainage opening 126 and parallel to the longitudinal direction 187 of the drainage body 162, the marking 246 is always parallel to the installed state of the drainage assembly 160 Longitudinal direction 187 of the drain body 162 aligned so that the correct orientation of the drain body 162 relative to the pelvic floor 124 by means of the marking 246 on the cover 170 is verifiable.

After assembly of the drain assembly 160 at the drain opening of the drain 122, water from the draining tank 108 by a between the peripheral wall of the cover 170 and the boundary surface 130 of the drain opening 126 remaining, preferably annularly around the cover 170 rotating gap 252 (see in particular Fig. 4 and 5 ) pass from an interior 254 of the drip tray 108 to the water inlet opening 174 of the drain body 162 and from there through the drain pipe 178 to a drain pipe, not shown, connected to a lower end of the drain pipe 178.

Since the abutment surfaces 146 of the basin bottom side abutment elements 144 are offset from the visible surface 128 of the pelvic floor 124 in the axial direction 136 to the drain body 162, the cover member 170 is completely received in the drain opening 126 in the mounted state of the drain assembly 160, so that no part of the cover 170 and no other component of the drain assembly 160 protrudes beyond the visible surface 128 of the pelvic floor 124 out into the interior 254 of the drip tray 108.

The structure of the not according to the invention formed vertical overflow 118 of the sink 100, which is arranged on the side wall 116 of the main basin 104, will in the following with reference to the Fig. 12 to 16 explained.

How best Fig. 13 As can be seen, the overflow opening 256 of the vertical overflow 118 is formed as a substantially cylindrical passage opening 258 in the associated flushing wall 120 (side wall 116) and has a substantially cylindrical boundary surface 260.

In addition to the overflow opening 256, the vertical overflow 118 includes a particular in the Fig. 13 and 14 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 drain 122, a fastening element 168 and a cover element 170, which is preferably constructed identically to the cover element 170 of the process 122.

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

The sealing element 266 may be formed as a simple sealing ring without sealing lips 188.

The frame member 268 is needed in the vertical overflow 118 to position the support member 166 at the overflow opening 256 which does not have flush wall-side abutment members 144 projecting into the interior of the overflow opening 256.

The frame element 268 comprises a substantially cylindrical peripheral wall 270, from the edge of which an annular abutment collar 272 projects outward in the radial direction.

From an abutment collar 272 opposite edge of the peripheral wall 270 is an annular collar 274 radially inwardly from.

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

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

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.

When mounting the overflow assembly 262 of the vertical overflow 118 at the overflow opening 256, the procedure is as follows:
The sealing element 266 is inserted into the abutment flange 176 of the overflow body 264.

The overflow body 264 with the sealing element 266 is positioned on the back of the sink wall 120 such that the central axis of the overflow body 264 passing through the receiving body 180 coincides with the center axis 232 of the overflow opening 256.

The carrier element 166 is inserted with the carrier element-side positioning members 220 in the slot 278 in the web 276 of the frame member 268, wherein the slot 278 delimiting areas of the web 276 are easily bent during movement along the ramp surfaces 231 until the web 276 the Rahmenelement- Locking elements 227 engages behind the side surfaces 229 of the carrier element-side positioning elements 220 and thus the carrier element 166 is latched to the frame member 268 to a unit to be handled together.

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 the frame element 268 against rotation relative to the carrier element 166 is secured. The lateral sections 282 of the slot 278 thus serve as frame element-side positioning elements 281st

The support member 166 and the frame member 268 are inserted into the overflow opening 256 until the frame member 268 abuts with its abutment collar 272 on the face 128 of the overflow opening 256 surrounding rinse wall 120, preferably substantially flat.

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

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 cooperate with the overflow body-side angle positioning elements 185, ensuring that the longitudinal direction 187 of the overflow body 264 passing through the two slots 184 of the receiving body 180, coincides with the longitudinal direction 210 of the support member 166 and the overflow body 264 is secured against rotation relative to the support member 166.

The fastener 168 is inserted into the fastener receiving portion 196 of the support member 166 and screwed with the external thread of its threaded portion 182 in the internal thread of the threaded sleeve 181 of the receiving body 180 of the overflow body 264 until the support member 166 from his in Fig. 11 illustrated relaxed initial state is transferred to its assembled state, in which the contact surfaces 216 of the contact elements 212 of the support member 166 are substantially flat and, preferably substantially flat, abut against the contact surface 283 of the annular collar 274 and the web 276 of the frame member 268.

In this state, the overflow body 264, the sealing element 266, the frame member 268 and the support member 166 are clamped by the fastener 168 against the sink wall 120.

Finally, the cover member 170 is releasably connected to the support member 166 by latching in the same manner as in the drain 122.

One in the Fig. 17 to 28 illustrated second embodiment of a sink 100 is different from that in the Fig. 1 to 16 represented by the embodiment of the vertical overflow 118 and the drain 122.

The drain opening 126 of the drain 122 differs from the drain opening 126 of the first embodiment substantially in that the boundary surface 130 of the drain opening 126 is not rotationally symmetrical, but has a substantially rectangular peripheral contour, with rounded corner regions (see Fig. 22 ).

The drain opening 126 of the drain 122, however, is also provided in this second embodiment with contact elements 144 projecting towards the center axis 132 and with bottom side positioning elements 158 in the form of grooves 148.

The support member 166 of the drain assembly 160 of the drain 122 differs in this embodiment of the support member 166 of the first embodiment substantially in that the carrier element-side locking elements 228 are not formed as peripheral portions of the fastener receiving 196, but as a plurality, for example, four locking projections 286, which are preferably arranged on side surfaces 188 of the contact elements 112 of the carrier element 166 and are engaged behind in the assembled state of the drain assembly 160 by the cover element-side locking elements 230.

In order to avoid a deflection of the carrier element 166, further support elements 188 are provided on the carrier element 166, which are aligned, for example, in a transverse direction 290 of the carrier element 166, which is perpendicular to the longitudinal direction 210 and to the axial direction 218 of the carrier element 166, from the fastener element receiver 196 protrude.

In the mounted state of the drain assembly 160, the end faces 290 of the support elements 288 remote from the fastening element receptacle 196 abut against the boundary surface 130 of the drain opening 126, preferably substantially flat (see FIG Fig. 20 ), which prevents the Central portion of the support member 166 bends under the action of the tensioning force generated by the fastening element 168 in the axial direction 218 to the drain body 162 through.

The end portions 214 of the contact elements 212 of the carrier element 166 facing away from the fastener element receptacle 196 may be provided with a chamfer 292 in this embodiment.

The cover element 170 is also not rotationally symmetrical in this embodiment of the drain 122, for adaptation to the essentially rectangular outlet opening 126 in cross section, but is substantially rectangular.

The cover element 170 may 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.

The covering element-side locking elements 230 are preferably formed integrally with the cover plate 242 in this embodiment of the cover 170 and arranged at the positions of the locking projections 286 of the support member 166 corresponding points of the circumference of the cover 170 (see Fig. 23 ).

When the cover member 170 is latched to the support member 166, by applying a pressure to an end portion 302 of the cover member disposed between two cover member side latch members 230 and a narrow side of the outer edge of the cover plate 242, the cover member 170 can be extended by one of the two end portions 302 adjacent cover element-side locking elements 230 extending axis are pivoted to a position in which the farther from the end portion 302 removed cover element-side locking elements 230 are unlocked by the associated carrier element-side locking elements 228 and the cover 170 can be easily grasped by a user of the sink 100 and completely detached from the support member 166.

The drain body 162, the sealing member 164 and the fastening member 168 may be formed in this second embodiment of the drain 122 as well as in the first embodiment described above.

Incidentally, in particular in the FIGS. 20 to 24 illustrated second embodiment of a process 122 in terms of structure, function and method of manufacture with the particular in the Fig. 4 to 11 illustrated in the first embodiment, reference is made to the above description in this regard.

The in the Fig. 25 to 28 represented not inventive invented 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 the support member 166 is omitted and instead a modified frame member 294 is used, which instead of a web 276 with a slot 278 for receiving a support member 166 has two fastener receptacles 196, which, preferably in one piece, are connected to a frame part 298 surrounding the in this case, for example, rectangular overflow opening 256.

Furthermore, the frame part 298 of the frame element 294 is provided with a plurality of, for example four, frame element-side locking elements 300, which cooperate with each associated cover element-side locking elements 230 to releasably fix the cover 170 by latching to the frame member 294.

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

Since the two fastening elements 168 in each case pass through a fastening element receptacle 296 on the frame element 294 and are screwed into an internal thread of the threaded sleeve 181 of the respective associated receiving body 180 in the mounted state of the overflow assembly 262, this already ensures that the longitudinal direction 187 of the overflow body 264 is in the longitudinal direction 284 of the frame member 294 and thus also with the longitudinal direction 248 of the cover member 170 coincides, without it being necessary to provide for this overflow body side Winkelpositionierelemente 185 or cover element side Winkelpositionierelemente 234.

When assembling the overflow assembly 262 at the overflow opening 256 of the vertical overflow 118 of the second embodiment of a sink 100, the procedure is as follows:
The sealing element 266 is inserted into the abutment 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 overflow opening 256 surrounding Spülenwand 120 so that the receiving body 180 of the overflow body 264 in the axial direction 136 with the fastener element receptacles 296 of the frame member 294 are aligned when the frame member 294 is inserted into the overflow opening 256.

The fasteners 168 are inserted into the fastener receptacles 296 of the frame member 294 and with their external threads in the internal thread of the threaded sleeves 181 of the receiving body 180 of the Overflow body 264 screwed until the overflow body 264, the sealing element 266 and the frame members 294 are braced by the fasteners 168 against the sink wall 120.

Finally, the cover 170 is placed on the frame member 294 and locked with the same.

Incidentally, the right in the Fig. 17 to 28 illustrated second embodiment of a sink 100 in terms of structure, function and method of manufacture with in the Fig. 1 to 16 illustrated in the first embodiment, reference is made to the above description in this regard.

When the drain 122 is referred to as a horizontal overflow, the drain opening 126 may be used as an overflow opening, the basin floor 124 of the sink 100 as a sink wall 120, the drain assembly 160 as an overflow assembly, the drain body 162 as an overflow body, the basin floor side, to obtain a consistent designation Positioning member 158 as a flushing-wall-side positioning member, the bottom-bottom contacting member 144 as a flush-wall-side abutment member, the bottom-bottom centering surface 156 as a spill-wall-side centering surface, the drain pipe 178 as an overflow pipe, the vertical overflow 188 as a second overflow, the overflow opening 256 of the vertical overflow 118 as a second overflow opening, the overflow assembly 262 as a second weir assembly, the outlet body side angular positioning member 185 as an overflow body side angular positioning member and the downcomer angular position be referred to as an overflow body positioning element.

The inventive design of the drain or horizontal overflow is basically also suitable for use in a vertical overflow, which is arranged on a side wall of a basin of the sink, which is aligned substantially vertically or inclined at a small acute angle relative to the vertical.
