Description

The present invention relates to a cover for covering a basin spout of a sink.

Such covers are used in particular to improve the visual impression of the sink, because the interior of the basin spout and about dirt accumulated therein is hidden from the eyes of a viewer.

Known covers of this type are fixed to a closure element of the basin spout, so that these covers are raised and lowered together with the closure element.

However, such a strong connection between the cover and the closure element makes it difficult to clean the basin spout and the closure element because the access to these elements of the sink is adversely affected by the cover fixed to the closure element.

In addition, an increased force must be applied to move the closure element from a closed position to an open position when the closure element is provided with a cover fixed thereto and the sink is filled with water, the weight of which rests on the cover. This makes it difficult to move the closure element into the open position and can lead to increased mechanical wear.

The present invention has for its object to provide a cover for covering a pelvic outlet of a sink, which reliably fulfills the capping function, without being rigidly coupled to a closure element of the cymbal spout.

• mindestens ein Zentrierelement, mittels welchem die Abdeckung in der Auflagestellung relativ zu einer Seitenwand des Beckenauslaufs, relativ zu einem auf den Beckenauslauf aufgelegten Auflegeteil und/oder relativ zu einem an dem Beckenauslauf angeordneten Verschlusselement des Beckenauslaufs zentrierbar ist.

This object is achieved in a cover with the features of the preamble of claim 1 according to the invention in that the cover is placed in a support position on an edge region of the pelvic outlet and / or on a laid-on pelvic outlet laying part and that the cover comprises:

• at least one centering element, by means of which the cover in the support position relative to a side wall of the basin spout, relative to a resting on the basin spout Auflegeteil and / or relative to a arranged on the basin spout closure element of the spout is centered.

It is achieved by resting the cover on an edge region of the pelvic outlet and / or on an applied on the pool spout Auflegeteil that the cover does not have to be supported on a closure element of the basin spout. The cover can therefore be decoupled from the movement of the closure element of the pelvic outlet. In particular, the cover can remain in the resting position on the basin outlet or on the laying-on part placed on the basin outlet when the closure element is moved from the closed position into the open position or from the open position into the closed position.

In this case, the laying-on part placed on the basin outlet can be embodied in particular as a basket-shaped sieve element which has the function of a residual sieve, can be placed on the edge region of the basin outlet and is preferably formed separately from a closure element, in particular a closure stopper, of the basin outlet that the screen element remains placed on the pelvic outlet when the closure element is transferred from a lowered position to a raised position.

The at least one centering element ensures that the cover according to the invention, despite the decoupling of the closure element of the basin outlet, maintains a desired positioning relative to the basin outlet, relative to a laying part laid on the basin outlet and / or relative to the closure element (within certain tolerances), so that the cover fulfills its function of covering the basin outlet of the sink, and in particular is not displaced laterally away from the basin outlet in the horizontal direction.

Preferably, the centering of the cover by means of the at least one centering element ensures that a (in the support position) vertical center axis of the cover substantially coincides with a vertical center axis of the basin outlet of the sink.

The basin outlet of the sink can be designed as an element produced separately from a basin floor of the sink and inserted into a section of the pelvic floor.

Alternatively, however, it can also be provided that the pelvic outlet is integrated into the pelvic floor of the sink and is preferably formed integrally with the pelvic floor (so-called integral outlet).

In the case of an integral with a pelvic floor of the sink basin outlet forms the edge region of the pelvic outlet, on which the cover can be placed in the support position, preferably at the same time a portion of the pelvic floor.

The closure element of the basin outlet, with which at least one outlet opening of the basin outlet can be closed, may in particular comprise a sieve basket (moved together with a sealing element of the closure element).

The cover, for example, by means of at least one centering in the support position of the cover on the edge region of the pelvic outlet and / or on an on the pelvic outlet Auflegeteil, in particular a screen element, be placed.

It is provided in a preferred embodiment of the cover according to the invention that a support point of the at least one centering, on which the centering rests on the edge region of the basin outlet or on the laid on the basin outlet Auflegeteil, in the support position of the cover below one adjacent to the centering Area of an underside of the cover is arranged so that in the support position of the cover, a gap between the cover and the edge of the basin outlet or the edge of the laying element is formed, can pass through the water from the sink into an interior of the basin spout. This ensures that the cover does not hinder the drainage of water from the sink when the outlet is open.

Alternatively or in addition to a resting of the cover on the edge region of the pelvic outlet or placed on the pelvic outlet laying part by means of at least one centering can also be provided that the cover in addition to the at least one centering element comprises at least one support element, by means of which the cover in the Support position can be placed on an edge region of the pelvic outlet and / or on a laying part placed on the pelvic outlet.

In this case, the at least one centering element is preferably not in the support position of the cover on the edge region of the basin outlet or on the laid-up on the basin outlet Auflegeteil. The centering element can in this case optimally for the fulfillment of the centering function be designed without a resting of the centering on the edge region of the pelvic outlet and / or on a laid on the pool spout Auflegeteil is required.

In order to achieve the most accurate possible centering of the centering relative to the pelvic outlet and / or relative to a closure element of the pelvic outlet and / or relative to a laying on the pelvic outlet laying part, it is advantageous if the cover more, preferably at least three, in particular at least six , Centering comprises.

It is particularly advantageous if the centering elements are arranged distributed along the circumference of the cover at substantially equal angular intervals.

In order to ensure that the position of the cover with respect to the horizontal in the support position is statically determined, it is advantageous if the cover comprises at least three support elements, by means of which the cover in the support position on the edge region of the pelvic outlet and / or on the Cymbal outlet on-laid Auflegeteil can be placed. As a result, a stable, statically determined three-point support of the cover is achieved at the edge region of the basin outlet or on the laying part.

It is particularly advantageous if the support elements are arranged distributed along the circumference of the cover at substantially equal angular intervals.

In order to avoid unintentional slipping of the cover relative to the pelvic outlet, it is advantageous if at least one support element comprises a buffer element of an elastomeric material, in particular of a silicone material. The material of such a buffer element has in Pairing with the material of the edge region of the pelvic outlet and / or with the material of an applied on the pool spill insert preferably a high coefficient of static friction, so that slipping of the cover relative to the pelvic outlet or relative to the Auflegeteil only under the action of a high displacement force is possible.

In a preferred embodiment of the cover according to the invention it is provided that the at least one support element projects beyond an area of an underside of the cover adjacent to the support element, so that in the support position of the cover a gap between the cover and the edge of the basin outlet and / or is formed between the cover and an applied on the pool spout Auflegeteil, can pass through the water from the sink into an interior of the basin spout. This ensures that the cover does not hinder the drainage of water from the sink when the pool outlet is open.

The vertical extent (height h) of the gap is preferably at least about 2 mm, in particular at least about 4 mm. This ensures that dirt particles contained in the rinse water do not stick to the edge of the cover, but pass through the gap in the covered by the cover interior of the basin spout and be discharged either through an outlet opening of the basin spout or on a screening device, in particular on a screen basket, be retained in the interior of the pelvic outlet.

In order to ensure that as large a passage cross-section as possible is available for the passage of water between the cover and the basin outlet, it is favorable if at least one support element is arranged in substantially the same angular position with respect to a central axis of the cover as a centering element the cover.

In this case, the support element assigned to a centering element is preferably arranged on the side of the centering element facing away from the center axis of the cover.

Between a support element and a centering element assigned to the same, a recess for receiving an edge region of a strainer basket is preferably provided in order to prevent lifting of the cover from the basin spout when the strainer basket is transferred from a lowered position to a raised position.

By means of the at least one support element and / or by means of at least one centering element, the cover rests loosely on the edge region of the pelvic outlet and / or on a laying part placed on the pelvic outlet and is preferably (within the tolerances predetermined by the at least one centering element) substantially horizontal Direction relative to the pelvic outlet and / or displaceable relative to the Auflegeteil.

In order to increase the tilt stability of the cover with a one-sided load thereof, it can be provided that the cover comprises at least one stabilizing element which is not in contact with the edge region of the basin outlet or a laying part placed on the basin outlet when the cover is unloaded in the Supporting position is located, but can be brought by tilting the cover in a one-sided loading of the cover in contact with the edge region of the pelvic outlet or with an attached to the pool spout Auflegeteil and then prevents further tilting of the cover.

Such a stabilizing element is in particular formed flush with the at least one support element, so that the stabilizing element in the load-free state of the cover protrudes less far down than the at least one support element.

Further, the stabilizing element is preferably arranged in the support position of the cover above the support point of a centering, on which rests the centering on the edge region of the pelvic outlet and / or on a laid on the pelvic outlet Auflegeteil.

Preferably, the cover comprises a plurality, in particular at least three, stabilizing elements.

In order not to unnecessarily reduce the passage cross section of the gap between the cover and the pelvic outlet in the resting position of the cover, it is favorable if at least one stabilizing element is arranged in substantially the same angular position with respect to a center axis of the cover as a centering element of the cover.

In this case, the stabilizing element assigned to a centering element is preferably arranged on the side of the centering element facing away from the center axis of the cover.

Between a stabilizing element and a centering element associated therewith a recess for receiving an edge region of a strainer basket is preferably provided in order to prevent lifting of the cover from the basin spout when the strainer basket is transferred from a lowered position to a raised position.

In order to enable self-centering of the cover by cooperating at least one centering element of the cover with a part of a closure element of the basin outlet, in particular with a screen basket, it is favorable if at least one centering element has a centering surface which is inclined relative to a center axis of the cover.

In this case, the centering surface is preferably inclined so that a base of the cover facing the end of the centering surface has a greater distance from the central axis of the cover than the base of the cover facing away from the centering surface.

In a preferred embodiment of the cover according to the invention it is provided that the cover comprises a base body and a cover element covering an upper side of the base body.

In this case, the covering element is preferably formed from a metallic material, in particular from a stainless steel material.

On the other hand, the main body is preferably made of a plastic material, for example of polypropylene (PP) and / or polybutylene terephthalate (PBT).

A particularly simple construction of the cover according to the invention results when the base body is formed integrally with at least one centering element of the cover.

Furthermore, it is preferably provided that the base body is formed integrally with at least one stabilizing element of the cover.

Furthermore, it is preferably provided that the base body is formed integrally with at least a portion of at least one support element of the cover.

The cover according to the invention is particularly suitable for use in an assembly which comprises a basin outlet of a sink and at least one cover according to the invention for covering the basin outlet.

Such an assembly may further comprise a strainer basket which is movable from a lowered position to a raised position.

The screen basket is preferably part of a closure element for closing the basin spout, which can be converted from a lowered position in which the closure element closes at least one outlet opening of the basin spout in a raised position in which the closure element releases the at least one outlet opening of the basin spout.

In this case, it is preferably provided that at least one centering element of the cover engages in an interior of the screen basket when the screen basket is in the raised position.

Furthermore, it can be provided that at least one centering element (preferably all centering elements) of the cover does not engage in the interior of the screen basket when the screen basket is in the lowered position.

Preferably, the cover rests with the at least one support element and / or with the at least one centering element on the edge region of the pelvic outlet when the filter basket is in the raised position.

When the strainer basket is in the lowered position, the cover is likewise located with the at least one support element and / or with the at least one centering element on the edge region of the basin spout.

Preferably, therefore, the cover is not moved in the vertical direction when the screen basket is moved from the lowered position to the raised position.

On the other hand, the cover can certainly perform a movement along the edge region of the pelvic outlet or along a resting on the pelvic Auflegeteils when the screen basket is moved from the lowered position to the raised position, by such a movement relative to the pelvic outlet and / or relative to the centering part to be centered when the screen basket is moved from the lowered position to the raised position.

In order to prevent the cover from being raised during the upward movement of the strainer basket from the basin outlet or from a laying part placed on the basin outlet, it can be provided, in particular, that the cover has at least one recess in which an edge region of the strainer basket engages when the strainer basket is in the raised position.

The cover according to the invention preferably lies loosely on an edge region of the basin outlet and / or on a laying-on part placed on the basin outlet.

The cover according to the invention is preferably not fixed to a closure element of the basin outlet, so that the cover does not have to be matched to the closure element so that it can be fixed to the closure element.

It is therefore possible to distribute the cover according to the invention independently of the closure element of the basin outlet.

The cover according to the invention can be used together with a multiplicity of different closure elements.

By means of the centering elements and optionally the support elements and / or the stabilization elements of the cover, an oblique position of the cover can be largely avoided.

By means of the centering elements of the cover, the cover can be positioned precisely above the pelvic outlet, in particular centrally.

For cleaning purposes, the cover resting loosely on the basin spout can simply be raised manually upwards from the edge area of the basin spout and / or from a laying part placed on the basin spout. Subsequently, a simple cleaning of the interior of the pelvic outlet and the closure element of the pelvic outlet, possibly including a screen basket, is possible.

Since the cover according to the invention preferably does not move in the vertical direction when the closure element of the basin spout is transferred from a lowered position to a raised position, the water column overlying the cover need not be raised when the spout outlet is opened (by lifting the closure element). The cover according to the invention therefore does not increase the force required to open the pelvic outlet.

This has a particularly favorable effect when the closure element of the pelvic outlet is moved by a motor, for example by an electric motor, or hydraulically.

The cover according to the invention is preferably not formed flush with the pelvic floor, so that the cover can be easily lifted by engaging an operator at the edge of the cover of the pelvic outlet, without having to take this special tool to help.

The cover of the invention is preferably designed to fit all basin outlet valves and drain fittings, but at least 3.5 inch basin outlet valves.

The cover according to the invention is centered by means of centering elements, each with an inclined centering surface by cooperation with a screen basket of a closure element of the basin spout or with an attached to the pool spout Auflegeteil, for example a screen element, but is preferably not on a coupled with the closure element screen basket. Thus, the cover according to the invention is decoupled from the underlying mechanism.

A collision of the cover with a screen basket underneath can be avoided, in particular, by providing a recess for receiving an edge region of the screen basket on webs on the underside of the cover.

By cooperation of the centering of the cover with a side wall of the basin spout or a laid on the pool spout Auflegeteils can also be prevented that the cover is laterally displaced so far that they no longer completely or not at all covers the pool spout and / or the Auflegeteil.

The cover according to the invention is suitable both for manually operated drain fittings and for eccentric operated drain fittings.

The cover according to the invention preferably covers the entire basin outlet.

By means of the cover it can be prevented that splashes of water occur when water jets from a mixer tap directly into the interior of the basin spout, in a laid on the basin spout Auflegeteil and / or in a strainer in the basin spout. Rather, such water jets now on the top of the cover, so that the water flows over the top of the cover and a gap at the bottom of the cover in the basin spout and water splashes are avoided.

Buffer elements made of an elastomer material can prevent slippage of the cover on the edge region of the pelvic spout and scratching the surface of the edge region of the pelvic spout in both the dry and in the wet state of the cover and the pelvic spout.

The loose cover of the pelvic outlet according to the invention can be used not only in conjunction with a strainer, which is mechanically connected to a closure element of the basin spout, but also in conjunction with a two-part system in which instead of the screen basket designed as a sieve Auflegeteil placed on the basin spout is moved and the closure element, separated from the screen element, from a lowered position to a raised position, without raising the screen element thereby.

In such an embodiment, the sieve element only the isolated function of a residue screen, while the pelvic outlet is separately sealed with a separate closure element, for example in the form of a sealing plug, which is located freely under the sieve.

It is also possible, the cover of the pelvic outlet directly on the Auflegeteil, for example in the form of a Siebelements hang up, especially because the Auflegeteil decoupled by the decoupled from the closure element Execution is not moved when the closure element is raised or lowered.

Further features and advantages of the invention are the subject of the following description and the drawings of exemplary embodiments.

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

One in the Fig. 1 and 2 partial illustrated, as a whole with 100 designated sink includes (not shown) side walls a pool bottom 102 with a cutout 104, in which a pelvic outlet 106 is inserted.

Like from the Fig. 1 and 2 It can be seen, the substantially cup-shaped pelvic outlet 106 comprises a substantially hollow cylindrical upper side wall portion 108, which merges over a (from an interior 110 of the pelvic spout 106 from) convexly curved transition region 112 in a substantially horizontally oriented edge portion 114 of the pelvic outlet 106.

Downwardly adjoining the lower edge of the upper side wall region 108 there is an annular, concave, curved central side wall region 116 (viewed from the inner space 110 of the pelvic spout 106), which extends over a (viewed from the inner space 110 of the pelvic spout 106). convex curved transition region 118 merges into a substantially conically shaped, downwardly tapering lower side wall region 120.

The upper sidewall region 108, the middle sidewall region 116, and the lower sidewall region 120 together form a sidewall 121 of the pelvic spout 106.

The lower side wall region 120 merges at its lower edge via a concave curved transition region 122 (seen from the interior 110 of the pelvic spout 106) into a substantially horizontally oriented bottom region 124 of the pelvic spout 106, which is connected to a plurality of, in the circumferential direction of the pelvis spout 106 Substantially equidistant successive outlet openings 126 is provided, through which when the basin outlet 106 open water from the sink 100 can drain into a below the basin outlet 106 arranged (not shown) drain pipe.

Furthermore, the bottom portion 124 of the pelvic outlet 106 is provided with a central passage opening 128, in which a guide sleeve 130 is inserted, from which in the Fig. 1 and 2 only a support collar 132 is shown, which rests from above on the bottom portion 124 of the pelvic outlet 106.

The basin outlet 106 is made in one piece, for example, from a sheet of a suitable metallic material, in particular a chromium-nickel steel, by deep-drawing operations.

The central through-hole 128 and the outlet openings 126 are made by stamping before or after forming the sheet.

In the guide sleeve 130 is a substantially cylindrical, along a vertical central axis 134 of the pelvic outlet 106 extending guide pin 136 of a designated as a whole 138 closure element inserted so that it is guided in the vertical direction slidable by the guide sleeve 130.

At its upper end, the guide pin 136 carries a screen basket 140 of the closure element 138.

The strainer basket 140 is held on the guide pin 136 by means of a sieve button 142.

The screen button 142 has an upper handle portion 144 and a lower threaded portion 146, wherein the threaded portion 146 extends through a central passage opening 148 of the screen basket 140 and is screwed into a threaded blind bore 150 at the top of the guide pin 136, so that the Siebknopf 140 and the guide pin 136 are engaged with each other and thereby both are secured to the screen basket 140.

The strainer basket 140 comprises a substantially circular, horizontally oriented central region 152 which is provided with the central passage opening 148.

The central region 152 is surrounded by a (from an inner space 154 of the screen basket 140) convexly curved lower side wall portion 156, at the top of a (viewed from the inner space 154 of the strainer 140 from) concave upper side wall portion 158 of the strainer 140th followed.

At its upper edge, the upper side wall region 158 merges into a marginal region 160 of the strainer basket 140 that is convexly curved (viewed from the interior 154 of the strainer basket 140).

The lower side wall portion 156 and the upper side wall portion 158 of the screen basket 140 are provided with a plurality of screen openings 162, which in the circumferential direction of the screen basket 140 equidistant successive and extending in the radial direction of the strainer basket 140 from the central portion 152 up to the upper side wall portion 158 of the screen basket 140 extend into it.

The screen basket 140 is made of a suitable metallic material, in particular of a chromium-nickel steel, by suitable forming operations, wherein the screen openings 162 and the central passage opening 148 in the central region 152 of the screen basket 140 are generated before or after the forming operations by punching.

The sieve button 142 may be made, for example, as a rotating part made of a metallic material or a plastic material or as an injection-molded part made of a suitable plastic material.

As further from the Fig. 1 and 2 As can be seen, the highest point of the top of the screen button 142 is lower than the edge portion 160 of the screen basket 140, so that the screen button 142 does not project beyond the upper edge of the outer peripheral wall of the screen basket 140.

At the bottom of the central portion 152 of the screen basket 140, an annular seal carrier 164 is fixed, which is formed substantially rotationally symmetrical.

The seal carrier 164 carries an annular, substantially rotationally symmetrical sealing element 166, which is formed of an elastically deformable material, for example of an elastomeric plastic material.

In the in Fig. 1 illustrated, lowered position of the strainer 140 is a sealing lip 168 of the sealing member 166 sealingly on the inside of the transition region 118 between the central side wall portion 116 and the lower side wall portion 120 of the Beckenauslaufs 106, so that the above the sealing element 166 lying part of the inner space 110 of the Beckenauslaufs 106 is liquid-tight from the lying below the sealing element 166 part of the inner space 110 is separated. Therefore, in the lowered position of the strainer basket 140, no water can pass from the upper part of the inner space 110 of the basin spout 106 into the lower part of the inner space 110 and thus to the outlet openings 126.

The closure element 138 with the screen basket 140 can by means of a (not shown) moving device in the vertical direction of the in Fig. 1 illustrated lowered position in the in Fig. 2 shown raised position and moved from the raised position back to the lowered position.

In the in Fig. 2 illustrated raised position of the closure element 138 and the strainer basket 140, the sealing element 166 is spaced from the side wall of the basin outlet 106 so that water from the upper part of the interior 110 of the basin spout 106 in the lower part of the interior 110 and thus can reach the outlet openings 126 ,

The sink 100 further comprises a cover 170 for covering the pelvic outlet 106, which individually in the Fig. 3 to 5 is shown.

The cover 170 comprises a main body 172 and a covering element 174 covering an upper side of the main body 172.

The main body 172 is preferably formed from a plastic material, in particular polypropylene (PP) or polybutylene terephthalate (PBT).

The cover element 174 is preferably formed of a metallic material, in particular of a stainless steel material.

The main body 172 comprises a substantially circular disk-shaped base 176, the upper side 178 of which (viewed from above) may be convexly curved.

The cover element 174 comprises a likewise essentially circular disk-shaped middle part 180, which is surrounded by an annular edge part 184 projecting downwards from the edge of the middle part 180 and resting against a peripheral surface 182 of the base 176 of the main body 172.

The cover element 174 can be fixed in particular by gluing or by crimping on the base body 172.

How best of the Fig. 3 and 5 can be seen, a plurality of functional elements 188 of the cover 170 are arranged on an underside 186 of the base 176 of the base body 172, namely several, for example six, centering 190, several, for example three, support elements 192 and a plurality, for example three, stabilizing elements 194th

The centering elements 190 are arranged radially inside the support elements 192 and the stabilizing elements 194, that is closer to the vertical center axis 196 of the cover 170 as the support members 192 and the stabilizing elements 194, and in the circumferential direction of the cover 170 is preferably substantially equidistant and preferably with in Substantially equal angular intervals (relative to the central axis 196 of the cover 170) are arranged.

Each of the centering elements 190 has a fin-like shape and has, on its radially outer side facing away from the center axis 196 of the cover, a centering surface 198 which is inclined relative to the center axis 196 such that an upper end 200 of the centering surface facing the base 176 of the main body 172 198 has a greater distance from the central axis 196 of the cover 170 than the base 176 facing away from the lower end 202 of the centering surface 198. The inclination of the centering surface 198 relative to the central axis 196 is preferably between about 20 ° and about 60 °.

In the case of several, for example three, of the centering elements 190 is radially outside of the respective centering element 190, that is at a greater distance from the central axis 196 of the cover 170, at substantially the same angular position (relative to the central axis 196) as the respective centering element 190 respectively one of the support elements 192 arranged.

Each of the support elements 192 comprises an annular buffer element receptacle 204 and a substantially cylindrical buffer element 206 accommodated in the buffer element receptacle 204.

The buffer element receptacle 204 is preferably formed integrally with the base 176 of the main body 172 of the cover 170.

The buffer member 206 is preferably formed of an elastomeric material, such as a silicone material.

The buffer element 206 can be inserted from below or from above into the respectively associated buffer element receptacle 204.

The insertion of a buffer element 206 into the buffer element receptacle 204 from above takes place before the fixing of the cover element 174 on the main body 172 of the cover.

When inserting the buffer element 206 from above, the buffer element 206 may in particular be provided with an undercut which holds the buffer element 206 in the buffer element receptacle 204 by positive locking and prevents the buffer element 206 from falling out of the buffer element receptacle 204.

Apart from positive locking, the buffer element 206 may also be held in the buffer element receptacle 204 by material adhesion, in particular by adhesive bonding, and / or by adhesion, in particular by interference fit.

Like from the Fig. 1 and 2 can be seen, the cover 170 is in a support position by means of the buffer members 206 of the support members 192 on the edge portion 114 of the pelvic outlet 106.

Since the support elements 192 project downward beyond the underside 186 of the base 176 of the base body 172 of the cover 170, in the support position of the cover 170 between the cover 170 and the edge region 114 of the pelvic outlet 106 (in the region between the cover 170 in the circumferential direction successive support elements 192), a gap 208 is formed (see FIGS Fig. 1 and 2 ), through which water from the above the cover 170 lying part of the interior 210 of the sink 100 can enter the interior 110 of the basin outlet 106.

The height h of the gap 208, that is to say its extent in the direction of the central axis 196 of the cover 170, which coincides with the direction of the vertical central axis 134 of the pelvic outlet 106 in the resting position of the cover 170, is preferably at least approximately 2 mm, in particular at least approximately 4 mm, so that dirt particles can reach this size through the gap 208 in the area under the cover 170 and hang in the strainer 140.

The gap 208 thus ensures a sufficient water passage between the part of the interior 210 of the sink 100 above the cover 170, on the one hand, and the interior 110 of the basin outlet 106, on the other hand.

The buffer elements 206 lying in the covering position of the cover 170 on the edge region 114 of the pelvic outlet 106, whose material in combination with the material of the pelvic outlet 110 has a relatively high coefficient of static friction, prevent the cover 170 from slipping relative to the pelvic outlet 106 in a substantially horizontal manner Direction, both in the dry and in the wet state of the cover 170 and the pelvic outlet 106th

When using three support elements 192, the support of the cover 170 is statically determined on the edge region 114 of the pelvic outlet 106 in the support position by a three-point support.

In order to increase the tilt stability of the cover 170 when loaded on one side thereof, the stabilizing elements 194 are provided which preferably at substantially the same angular position (relative to the central axis 196 of the cover 170) as a respective associated centering element 190 and in particular radially outwardly of each associated centering element 190 (that is, with a greater distance from the central axis 196 than the respective associated centering element 190) on the base body 172 of the cover 170 are formed.

Preferably, the stabilizing elements 194 are integrally formed with the base 176 of the cover 170.

Each of the stabilizing elements 194 is formed, for example, as a projecting from the bottom 186 of the base 176 of the Grundköpers 172 of the cover 170 downward protrusion, the stabilizing elements 194 are formed flush with the support members 192, so that the stabilizing elements 194 in the unloaded state of the cover 170th less far down than the support members 192 and a lower support surface 212 of each stabilizing element 194 in this non-load state is higher than the bearing surfaces 214 of the support members 192, which are arranged on the underside of the buffer members 206.

In the load-free state of the cover 170 thus the bearing surfaces 212 of the stabilizing elements 194 are spaced by a small gap from the top of the edge portion 114 of the pelvic outlet 106. Only when the cover 170 is loaded on one side, for example by placing a pot on a region of the cover 170, the cover 170 tilts relative to the horizontal until one or more of the stabilizing elements 194 in the loaded region of the cover 170 in contact with the edge region 114 of the basin spout 106, thereby preventing further tilting of the cover 170 relative to the horizontal.

The stabilizing elements 194 thus contribute to an increased tilting stability of the cover 170.

Each of the stabilizing elements 194 may be formed, for example, in the form of a narrow fin which is oriented substantially in the radial direction of the center axis 196 of the cover 170 and has a greater extent in this radial direction than in the circumferential direction of the cover 170.

In particular, it can be provided that the thickness of each stabilizing element 194, that is to say its extent in the direction perpendicular to the radial direction of the center axis 196 and parallel to the underside of the base 176, is substantially the same size as the thickness of each associated centering element 190, that is, the extension of the relevant centering element 190 perpendicular to the radial direction of the central axis 196 and parallel to the bottom 186 of the base 176th

In order to achieve that the strainer basket 140 of the closure element 138 in the in Fig. 2 shown raised position, without in this case the cover 170 is lifted from the support position on the pelvic outlet up, the cover 170 is preferably provided on its underside with recesses 216, in which the edge portion 160 of the screen basket 140 can engage when the strainer 140 is moved from the lowered position to the raised position (see Fig. 2 ).

The recesses 216 therefore preferably have such a radial distance from the center axis 196 of the cover 170, which substantially corresponds to the distance of the edge region 160 of the screen basket 140 from the vertical center axis 134 of the basin outlet 106.

Upon precise centering of the cover 170 on the pelvic outlet 106, the vertical center axis 196 of the cover 170 coincides with the vertical center axis 134 of the pelvic outlet 106.

If a support element 192 or a stabilizing element 194 is associated with a centering element 190 of the cover 170, a recess 216 is preferably provided between the respective centering element 190 and the associated support element 192 or the associated stabilizing element 194, the upper edge surface 218 of which is higher than the lower one End 202 of the centering surface 198 of the respective centering element 190 and higher than the support surface 214 of the associated support member 192 and higher than the support surface 212 of the associated stabilizing element 194th

Above the respective recess 216, the centering element 190 and the respectively assigned support element 192 or the respectively associated stabilization element 194 can be connected to one another by a connecting web 220, preferably in one piece.

Preferably, support elements 192 and stabilizing elements 194 follow one another alternately in the circumferential direction of the cover 170.

The centering elements 190, the support elements 192 and / or the stabilizing elements preferably extend per element over a circumferential angle (relative to the bottom axis 186 of the base 176 vertical center axis 196 of the cover 170) of at most about 40 °, in particular of at most about 30 °, so that the remaining between the functional elements 188 gap 208 has a sufficient passage cross-section.

The closure element 138 of the pelvic outlet 106 with the strainer basket 140 may in principle arbitrary manner, for example by manual operation or by motor operation, in particular by electromotive or hydraulic actuation of the in Fig. 1 illustrated lowered position in the in Fig. 2 shown raised position to be moved.

In the in Fig. 1 illustrated lowered state of the screen basket 140, the centering elements 190 of the cover 170 engage only slightly or not at all in the interior 154 of the screen basket 140 a.

In this lowered state of the screen basket 140, however, the centering elements 190 prevent the cover 170 from slipping out of the region of the pelvic outlet 106, because the centering surface 198 of at least one centering element 190 is horizontally displaced beyond the side wall 120 by a horizontal displacement of the cover 170 the Beckenauslaufs 106 abuts and then prevents further displacement in this horizontal direction.

When the closure member 138 is connected to the strainer basket 140 from the in Fig. 1 illustrated lowered position in the in Fig. 2 Self-centering of the cover 170 is effected by means of the centering elements 190, because the centering surface 198 of a centering element 190, which is too far away from the central axis 134 of the pelvic outlet 106, comes into contact with the edge region 160 of the screen basket 140 and from the upwardly moving edge portion 160 is pushed radially inwardly.

In the raised state of the closure element 138 and the strainer basket 140, which in Fig. 2 is shown, the cover 170 is held by the centering elements 190 in their centered on the pelvic outlet 106 position and secured against horizontal displacement.

In this case, the centering surfaces 198 of the centering elements 190 in the raised position of the screen basket 140 may rest against the screen basket 140 or be spaced apart from the screen basket 140 by a small tolerance distance.

The centering elements 190 of the cover 170 are designed so that they do not come into contact with the screen button 142 of the closure element 138 and interact with differently shaped screen baskets 140 so that the cover 170 through the respective screen basket 140 in its movement from the lowered position in the lifted position with respect to the pelvic outlet 106 is centered.

In the in the Fig. 1 and 2 illustrated embodiment of a sink 100 with basin outlet 106 and cover 170 is the pelvic outlet 106th manufactured separately from the pelvic floor 102 of the sink 100 and inserted into a section 104 of the pelvic floor 102.

In an alternative embodiment, however, it can also be provided that the pelvic outlet 106 is integrated into the pelvic floor 102 of the sink 100 and is preferably formed integrally with the pelvic floor 102 (so-called integral outlet).

In this case, the pelvic outlet 106 is preferably formed of the same material as the pelvic floor 102 of the sink 100. Therefore, in addition to stainless steel materials, other materials such as plastic materials, ceramics, or composites may be used to form the pelvic outlet 106.

One in the Fig. 6 and 7 illustrated second embodiment of a pelvic outlet 106 with a closure element 138 disposed thereon differs from that in the Fig. 1 to 6 in that the closure element 138 does not comprise a rigidly coupled sieve basket 140, but that instead a laying part 224 designed as a sieve element 222 is provided which has a (for example substantially horizontally oriented) edge region 226 on a stepped region 228 of the side wall 121 of the Beckenauslaufs 106 rests.

The sieve element 222 is substantially cup-shaped and provided in its bottom region with sieve openings 230, through which water can flow from an interior 232 of the sieve 222 down to the lying below the Siebelements 222 part of the interior 110 of the basin outlet 106, with larger dirt particles in the Sieve 222 are retained.

A somewhat raised, central region 234 of the sieve element 222 carries a sieve button 142, as in the sieve basket 140 of the first embodiment.

In this embodiment, the closure element 138 is mechanically decoupled from the sieve element 222 and comprises a closure stopper 236, which is provided at its circumference with an annular groove 238 into which a sealing element 166 is inserted.

The sealing element 166 has a radially outwardly facing sealing lip 168, with which the sealing element 166 in the in Fig. 6 illustrated, lowered position of the closure member 138 sealingly against the lower portion of the side wall 121 of the pelvic outlet 106, just above the transition region 118, is applied.

The closure plug 236 is provided on its underside 240 with a threaded blind hole 242 into which a threaded portion 244 is screwed at the upper end of a guide pin 136.

The guide pin 136 is, as in the first embodiment, by means of a (not shown) moving device by manual operation or by motor actuation of the in Fig. 6 illustrated lowered position in the in Fig. 7 shown raised position movable, whereby the pelvic outlet 106 is opened for the flow of water.

Also in the in Fig. 7 illustrated raised position of the closure member 138, the upper edge of the closure member 138 is disposed below the bottom of Siebelements 222, so that the sieve 222 and certainly the arranged above the sieve 222 cover 170 by the transfer of the closure member 138 from the lowered position in the raised Not raised position and not be lifted from the basin outlet 106.

The laying part 224 in the form of the sieve element 222 and the cover 170 are thus mechanically completely decoupled from the closure element 138 and from its vertical movement.

The cover 170 is in the in the Fig. 6 and 7 illustrated second embodiment as well as in the in the Fig. 1 to 5 illustrated first embodiment and is particularly in the support position with the support elements 192 on the edge portion 114 of the pelvic outlet 106.

By interaction of the centering elements 190 with the centering surfaces 198 on the one hand and the peripheral wall 246 of the Auflegeteils 224 on the other hand, the cover 170 is centered relative to the Auflegeteil 224 (within certain tolerances) when the cover 170 is placed on the Beckenauslauf 106.

Incidentally, the right in the Fig. 6 and 7 illustrated second embodiment of a pelvic outlet 106 and a cover 170 in terms of structure, manufacturing method and function with in the Fig. 1 to 5 illustrated in the first embodiment, reference is made to the above description in this regard.

One in the Fig. 8 and 9 illustrated third embodiment of a pelvic outlet 106 with a closure element 138 disposed thereon, a separately formed from the closure member 138 Auflegeteil 224 and a cover 170 differs from that in the Fig. 6 and 7 illustrated second embodiment, characterized in that the support elements 192 of the cover 170 radially further inward, that is closer to the center axis 196 of the cover 170, are arranged as in the second embodiment (or even in the in Fig. 1 to 5 illustrated first embodiment). This eliminates the provided in the first two embodiments recesses 216 between the centering elements 190 on the one hand and the respective associated support members 192 and the respective associated stabilizing elements 194 on the other.

Like from the Fig. 8 and 9 can be seen, are in the support position of the cover 170, the support elements 192 with the lower sides of the buffer elements 206 no longer on the edge portion 114 of the pelvic outlet 106, but on the edge portion 226 of the Auflegeteils 224 on.

Since the laying-on part 224, for example in the form of a sieve element 222, is not deflected in the vertical direction, even in this embodiment, when the closure element 138 differs from the one shown in FIG Fig. 8 illustrated lowered position in the in Fig. 9 is shown in this third embodiment, the cover 170 is not lifted from the pelvic outlet 106 when the closure element 138 is transferred from the closed position to the open position.

Incidentally, the right in the Fig. 8 and 9 illustrated third embodiment of a pelvic outlet 106 with cover 170 in terms of structure, manufacturing method and function with in the Fig. 6 and 7 illustrated second embodiment, to the above description in this respect reference is made.

One in the Fig. 10 and 11 illustrated fourth embodiment of a pelvic outlet 106 with closure element 138 disposed thereon, separated from the closure member 138 formed Auflegenteil 224 and the pelvic outlet covering cover 170 differs from that in the Fig. 8 and 9 illustrated third embodiment in that the cover 170 has no support elements 192 with buffer elements 206, but only at support points 248 in the region of the centering surfaces 198 of the centering 190 on the peripheral wall 246 of the Auflegeteils 224, in particular in the form of a Siebelements 222 rests.

In this embodiment, preferably each centering element 190 is assigned a stabilizing element 194 arranged radially outside the centering element 190, that is to say at a greater distance from the center axis 196 of the cover 170 than the respective centering element 190.

The recesses 216 provided in the first and the second embodiment between in each case one centering element 190 and the associated stabilizing element 194 can also be dispensed with in this embodiment.

Despite the absence of the support elements 192 in this embodiment, a sufficient tilting stability of the cover 170 is given because the cover 170 rests on each centering element 190 via a support point 248 on the Auflegeteil 224 and beyond each centering element 190 is assigned a stabilizing element 194 which by Tilting the cover 170 in a one-sided loading of the cover 170 comes into contact with the edge portion 114 of the Beckenauslaufs 106 and then prevents further tilting of the cover 170, as described in detail in connection with the first embodiment.

Incidentally, the right in the Fig. 10 and 11 illustrated fourth embodiment of a pelvic outlet 106 with cover 170 in terms of structure, method of manufacture and function with in the Fig. 8 and 9 illustrated third embodiment, the above description of which reference is made.

In the Fig. 6 to 11 the pelvic floor 102 of the sink 100 is not shown. As with the in the Fig. 1 to 5 illustrated first embodiment can also in the in the Fig. 6 to 11 illustrated further embodiments of the pelvic outlet 106 made separately from the pelvic floor 106 of the sink and inserted into a section 104 of the pelvic floor 102.

Alternatively, in these other embodiments, the pelvic outlet 106 integrated into the pelvic floor 102 of the sink 100 and preferably be integrally formed with the pelvic floor 102 (so-called integral outlet).
