One in the Fig. 1 to 7 illustrated basin 100 is formed substantially parallelepipedic and comprises a in the assembled state of the basin 100 substantially horizontally oriented pelvic floor 102 with a drain opening formed thereon 103 and four of the pelvic floor 102 substantially vertically upwardly extending pool walls 104, the interior of the 106 Basin 100 facing inner sides of the interior 106 laterally defining major surfaces 108 of the pool walls 104 form.

At their upper edges, the basin walls 104 carry an annular circumferential pelvic flange 110, which can serve to secure the pelvis 100 to a worktop (not shown).

The illustrated basin 100 may be used as part of a sink, and more particularly as a basement basin.

However, such a basin 100 may also be embedded in a sink body, which includes, for example, a drainer, a fitting support surface and / or at least one additional basin in addition to the basin 100.

The in the assembled state of the basin 100 by the user of the basin 100 farthest rear basin wall 104 is provided with an overflow opening 112 (see in particular Fig. 2 and 3 ), which is embedded in the main surface 108 of this pool wall 104.

As best of the sectional view of the Fig. 4 can be seen, the overflow opening 112 is surrounded at its edge by an annular over the overflow opening 112 encircling overflow edge portion 114 of the pool wall 104, which is bent over the main surface 108 of the pool wall 104 by an angle of almost 90 ° to the outer space 116 of the tank 100 out is.

How out Fig. 2 It can be seen, the overflow edge portion 114 projects in its vertically extending portions 118 further into the outer space 116 of the basin 100 than in its horizontally extending portions 120th

From the outer edge of each of the vertically extending portions 118 of the overflow edge portion 114 is in each case a retaining tab 122 in the direction of the vertical transverse center plane 124 of the overflow opening 112 before.

Each of the retaining tabs 122 is folded at an angle of approximately 90 ° with respect to the respectively associated vertically extending portion 118 of the overflow edge portion 114 to the vertical transverse center plane 124, so that each retaining tab 122 forms a holding portion 126 folded twice over the main surface 108 of the pool wall 104 the inner space 106 of the basin 100 facing the front 127 extends substantially parallel to the main surface 108 of the pool wall 104.

By contrast, the lower, essentially horizontally extending section 125 of the overflow edge region 114 is merely folded so that the water can escape from the inner space 106 of the basin barrier-free via the essentially horizontal upper side 123 of the lower section 125 of the overflow edge region 114, without departing from the overflow edge region 114 to run back into the interior 106 of the basin. As a result, an increased cleanliness of the basin 100 is achieved.

At each of the holding portions 126, a substantially circular fastener passage 128 is formed.

The basin 100 may for example be made of a metallic material, in particular of a steel material, for example of a stainless steel material, in particular by a deep-drawing process, wherein the drain opening 103 and the overflow opening 112 punched before or after the deep drawing process of the metallic material and by one or several embossing or bending operations have been brought in the form described above.

At the overflow opening 112 of the basin 100 is a in the Fig. 5 to 7 arranged overflow assembly 130, which one in the 8 to 11 individually shown overflow body 132, two in the FIGS. 15 and 16 individually shown fasteners 134 for releasably securing the overflow body 132 to the support portions 126 of the pool wall 104 and a in the Fig. 12 to 14 individually shown cover 136, through which a water inlet opening 138 of the overflow body 132 is at least partially covered covers.

The in the 8 to 11 shown overflow body 132 is integrally formed, for example, from a suitable thermoplastically processable plastic material by an injection molding process, and comprises a in substantially rectangular, annularly closed contact area 140, which encloses the water inlet opening 138 of the overflow body 132.

The abutment region 140 has a contact surface 144, which faces the outer surface 142 of the pelvic wall 104 in the assembled state of the overflow body 132, and which is provided with a groove 146 which extends annularly through the abutment region 140.

Like from the Fig. 6 and 7 can be seen, in the groove 146 an annularly closed sealing element 148 is arranged, which may be formed for example as an O-ring.

The sealing element 148 preferably consists of a resiliently deformable under contact pressure elastomeric material.

The volume of the sealing element 148 is dimensioned so that it is in the Fig. 6 and 7 illustrated mounted state of the overflow body 132 substantially flat against the outer side 142 of the pool wall 104 and thereby the groove 146 substantially completely fills.

The abutment region 140 of the overflow body 132 is supported by a circumferential wall 150 that runs along the rear side of the abutment region 140 and protrudes toward the abutment region 140 from a rear wall 152 of the overflow body 132 closing the overflow body 132 at the rear.

Like from the Fig. 6 and 9 can be seen, a portion 154 of the rear wall 152 a in the assembled state of the overflow body 132 against the main surface 108 of the pelvic wall 104 inclined outside 156 have; In particular, it may be provided that this outer side 156 is inclined outward at an angle of, for example, approximately 10 ° to approximately 30 °, as viewed in the downward direction.

As in particular from the 10 and 11 can be seen, the shell wall 150 may have portions 158 which are not perpendicular to the main surface 108 of the pool wall 104, but at an acute angle, for example, about 30 ° to about 40 ° so inclined to the main surface 108 that the overflow body 132 to its rear side facing away from the abutment region 140 tapers.

As best of the sectional view of the Fig. 7 It can be seen, the rear wall 152 of the overflow body 132 carries for each fastener 134 each have a substantially cylindrical receiving body 160 which extends from the rear wall 152 from the front, ie in the mounted state of the overflow body 132 to the interior 106 of the tank 100 out ,

Each of these receiving body 160 is penetrated by a in the assembled state of the overflow body 132 approximately horizontally extending cylindrical receiving bore 162 which is provided with an internal thread 164.

Each of the receiving holes 162 serves to receive a respective fastening means 134, one of which in the FIGS. 15 and 16 is shown.

The fastening means 134 is designed as a hollow screw 166, which has a screw head 168 with a substantially flat front side 170, which is provided with a radially extending receiving groove 172 for a screwdriver, along the longitudinal axis 174 of the hollow screw 166 adjoining the screw head 168 shaft region 176 and a along the longitudinal axis 174 adjoining the shaft portion 176 threaded portion 178 having an external thread 180 includes.

The hollow screw 166 is penetrated from the front side 170 of the screw head 168 to its end remote from the screw head 168 by a stepped through-hole 182, which a front portion 184 with having a smaller diameter and a rear portion 186 of larger diameter.

Arranged in the rear portion 186 of the stepped through-bore 182 is a substantially cylindrical magnet member 188 which substantially completely fills the rear portion 186 of the through-bore 182 and extends to the front portion 184 at which the two portions 184 and 186 of the through-bore 182 separate Level 190 is supported.

The magnetic element 188 is materially connected, in particular by gluing, with the hollow screw 166 and thereby held in the rear portion 186 of the through hole.

Magnetic element 188 is formed by a permanent magnet from which one pole (for example the north pole) points towards screw head 168, while the other pole (for example the south pole) points in the direction away from screw head 168.

How out Fig. 7 It can be seen, is in the mounted state of the overflow body 132, each hollow screw 166 with the back 192 of its screw head 168 substantially flat against the front 127 of the respective associated holding portion 126 of the pelvic wall 104, wherein the shaft portion 176 of the hollow screw 166 through the fastener Passage opening 128 of the holding portion 126 extends therethrough and the threaded portion 178 of the hollow screw 166 is screwed with its external thread 180 in the complementary internal thread 164 of the respective associated receiving bore 162. In this way, the overflow body 132 is releasably fixed to the pelvic wall 104, wherein by the screwing of the hollow screws 166 into the mounting holes 162 of the contact area 140 of the overflow body 132 with the sealing member 148 is pulled from the outside against the pool wall 104 and pressed against the outside 142 of the pool wall 104, so that the overflow body 132 rests watertight on the outside 142 of the ceiling wall 104 by the sealing effect of the sealing element 148.

Each receiving bore 162 is formed as a through opening opening onto the rear side of the overflow body 132, so that the respective associated fastening means 134 can protrude beyond the back of the overflow body 132 to the outside.

Like from the Fig. 6 and 8th it can be seen, each of the two receiving body 160 of the overflow body 132 is connected via a web 196 with a respective adjacent vertical portion of the shell wall 150 of the overflow body 132 in order to increase the mechanical stability of the overflow body 132.

Furthermore, the overflow body 132 comprises a drainage channel 198 with a substantially rectangular cross-section, which is hollow, wherein the cavity 200 formed in the drainage channel 198 with a water inlet space 202 of the overflow body 132 surrounded by the shell wall 150, the rear wall 152 and the abutment portion 140 of the overflow body 132 communicates ( Fig. 6 ).

The lower end of the drainage channel 198 is connected by means of a (not shown) connecting device with a (not shown) drainage pipe of the basin 100, which is connected to the drain opening 103 of the basin 100.

That in the Fig. 12 to 14 shown, leading to the water inlet space 202 of the overflow body 132 water inlet opening 138 of the overflow body 132 and the overflow opening 112 of the pool wall 104 partially covering cover 136 comprises a substantially rectangular cover plate 204 and two in the longitudinal direction of the cover plate 204 from each other spaced apart retaining elements 206 in the form of substantially cylindrical retaining bolts 208 which project rearwardly substantially perpendicular to a front side 210 of the cover plate 204 from a rear side 212 of the cover plate 204.

Each of the retaining bolts 208 is made of a magnetizable ferromagnetic material, in particular of a steel material.

Further, each of the retaining bolts 208 is provided at its end facing away from the cover plate 204 with a chamfer 214 to be more easily inserted into the front portion 184 of the stepped through hole 182 of one of the hollow screws 166 can.

The cover plate 204 is preferably made of a metallic material, in particular of a steel material, for example of a stainless steel material.

The retaining bolts 208 are welded to the back 212 of the cover plate 204, in such a way that neither the welds 218 nor the retaining bolts 208 themselves shine through on the front side 210 of the cover plate 204.

The front side 210 of the cover plate 204 is made of a prefabricated material.

The welds 218 are protected by a coating against corrosion.

Alternatively to an attachment of the retaining bolts 208 to the cover plate 204 by welding can also be provided that the cover plate 204 is formed of a plastic material, in which the retaining bolts 208 formed, in particular cast, are.

The cover plate 204 may be formed in two parts and be provided with a flange of a different material from the base body of the cover plate 204, for example, of a metallic material, in particular of a steel material, for example of a stainless steel material.

Like from the Fig. 6 and 7 It can be seen, the cover member 136 is thereby releasably secured to the overflow body 132, that it is held with the retaining bolts 208 in the front portions 184 of the stepped through holes 182 of the hollow screws 166, with which the overflow body 132 is held on the holding portions 126 of the pool wall 104 is inserted until the cover plate 204 facing away from the ends of the retaining bolts 208 abut the front of the magnetic elements 188.

The cover member 136 is then retained on the overflow body 132 by the magnetic attraction force between the magnetizable material holding pins 208 and the magnetic members 188 until a peel force overcoming the magnetic attraction force is applied to the cover plate 204 by an operator.

By the two holding elements 206, whose distance in the longitudinal direction of the cover 136 corresponds to the distance of the fastener passage openings 128 in the holding portions 126 of the pool wall 104, the cover 136 is positioned exactly on the pool wall 104 and with respect to the water inlet opening 138 of the overflow body 132nd exactly centered.

The length of the holding elements 206 is matched to the position of the stop surface at the front end of the magnetic elements 188 that completely inserted into the fastener 134 cover 136 with the front 210 of its cover 204 does not extend beyond the main surface 108 of the pool wall 104 in the interior 106th of the basin 100, but rather is set back a small distance from the main surface 108 to the outside of the basin 100.

Like from the Fig. 6 and 7 can be seen, remains between the cover plate 204 of the cover 136 on the one hand and the overflow edge portion 114 of the pool wall 104 on the other hand, an annular circumferential gap 216, can enter through the water from the interior 106 of the basin 100 in the water inlet space 202 of the overflow body 132, from where the Water can then flow down through the drainage channel 198 down into the drain pipe.

The edge of the cover plate 204 is free of holding elements, so that the inflow of water into the water inlet space 202 is in no way hindered.

Since the abutment region 140 of the overflow body 132 rests against the outer side 142 of the pelvic wall 104, in the mounted state of the overflow body 132, the abutment region 140 does not project beyond the main surface 108 of the pelvic wall 104 into the interior 106 of the pelvis 100.

The resulting rimless geometry of the overflow body 132 enables barrier-free cleaning of the basin 100, in particular of the edge region of the pool wall 104 surrounding the overflow opening 112.

Due to the magnetic attachment of the cover element 136 on the overflow body 132, a tool-free assembly and disassembly of the cover element 136 is made possible.

To mount the overflow assembly 130 described above at the overflow opening 112 of the pool wall 104, the overflow body 132 is moved from the outside of the pool 100 against the outside 142 of the pool wall 104 so that the contact area 140 abuts the outside 142 of the pool wall 104 and the overflow opening 112 of the pool wall 104 surrounds.

The overflow body 132 is positioned on the pool wall 104 so that the receiving bores 162 of the overflow body 132 are aligned with the fastener passage openings 128 in the holding areas 126 of the pool wall 104.

Subsequently, the fastening means 134 are introduced in the form of hollow screws 166 from the interior 106 of the basin 100 forth through the fastener passage openings 128 in the mounting holes 162 and screwed into the internal threads 164 of the mounting holes 162 until the screw heads 168 abut the retaining portions 126, whereby the Bearing portion 140 of the overflow body 132 is pressed with the sealing element 148 against the outside 142 of the pool wall 104.

Finally, the cover member 136 is positioned in the overflow body 132 as previously described by inserting the retaining bolts 208 into the forward portions 184 of the stepped through-holes 182 of the banjo bolts 166 and held in that position by the magnetic attraction between the retaining members 206 and the magnetic members 188 ,

In a variant of the embodiment of an overflow assembly 130 described above, it may also be provided that the magnetic elements 188 are not arranged on the fastening means 134 but instead on the cover element 136.

In this case, magnetizable elements are then provided on the fastening means 134 and / or on the overflow body 132, which retain the magnetic elements on the cover element 136 by magnetic attraction.

Furthermore, it can also be provided that magnetic elements are present both on the cover element 136 and on the fastening means 134 and / or on the overflow body 132, in which case, however, the correct polarity of the magnetic elements is to be observed in order to generate a magnetic attraction force on the cover element 136.

As an alternative to the substantially rectangular configuration of the cover plate 204 described above, provision can also be made for the cover plate 204 to have a different shape, in particular a round or oval shape.

When using a circular cover plate 204, it may be sufficient if only one holding element 206 is used, which is preferably arranged centrally on the cover plate 204. In this case, then only one fastening means 134 for releasably securing the overflow body 132 to the pool wall 104 is required.

The front 210 of the cover plate 204 may be provided in all embodiments with a label or ornament, for example with a manufacturer's identification.
