EP3173541B1 - Assembly for sealing an outlet opening of a pool - Google Patents

Description

The present invention relates to an assembly for closing a drain opening of a basin, in particular a basin of a sink, for example a kitchen sink, the assembly comprising a sieve element with at least one sieve opening and a sealing element which, in a closed position, bears sealingly against a drain cup and in an open position Allows liquid to drain from the pool through the drain opening.

In known assemblies of this type, the sieve element is rigidly connected to the sealing element, so that the sieve element moves upward away from the drain cup when the sealing element is brought from the closed position into the open position.

It is also known to design the sieve element and the sealing element as completely independent elements which are arranged separately on the drain cup.

The disadvantage here is that the sieve element must be removed from the drain cup in order to move the sealing element from the closed position to the open position or from the open position to the closed position by manual actuation (by the user of the basin on which the assembly is arranged) convict.

Manual actuation of the sealing element is understood in this description and in the appended claims to mean an actuation in which the user engages with his hand on the sieve element or on the sealing element in order to move the sealing element from the closed position to the open position or from the open position to the To transfer the closed position. An operation in which the user is outside the pelvis arranged actuating element used to transfer the sealing element by means of a lifting device coupled to the actuating element from the closed position into the open position or from the open position into the closed position is not a manual actuation.

The DE 10 2012 215 763 A1 discloses an assembly for closing a drain opening arranged on a drain cup according to the preamble of claim 1.

The US 4,320,540 A discloses an assembly of a sieve element and a sealing element, the sieve element and the sealing element being rigidly coupled to one another and not being movable relative to one another in a vertical direction.

The present invention has for its object to provide an assembly of the type mentioned, which makes it possible to transfer the sealing element by manual actuation from the closed position to the open position and / or from the open position to the closed position without this manual actuation, the sieve element must be removed from the drain cup and without the sieve element and the sealing element being rigidly connected to one another.

This object is achieved by an assembly according to claim 1.

The present invention is therefore based on the concept of coupling the sealing element and the sieve element to one another by means of the actuating device in such a way that the sealing element can be transferred from the closed position to the open position and / or from the open position to the closed position by movement of the sieve element without The sieve element must first be removed from the goblet, but the sieve element is not rigidly connected to the sealing element, so that the sieve element and / or the sealing element can be raised without the other element, that is to say the sealing element or the sieve element, at the same time , is raised.

The screen element can be lifted from a working position on the drain cup without the sealing element being lifted together with the screen element.

The sieve element can be completely disengaged from the sealing element without the sealing element being raised, in particular being lifted off the drain cup.

The sieve element preferably comprises a grip section on which a user of the assembly can grip in order to move the sieve element, in particular to rotate it.

The screen element preferably covers the sealing element in the assembled state of the assembly, so that the sealing element is not accessible for direct movement thereof by a user of the assembly.

In a preferred embodiment of the invention, it is provided that the actuating device comprises a coupling device, by means of which the sieve element and the sealing element are coupled to one another in such a way that a rotational movement of the sieve element about a rotational axis causes a rotational movement of the sealing element.

In particular, the coupling device can comprise a coupling projection and a coupling receptacle, in which the coupling projection engages when the sieve element and the sealing element are coupled to one another.

So that the user can easily create the coupling between the sieve element and the sealing element, it is advantageous if the coupling projection can be inserted into the coupling receptacle in two or more different angular positions relative to the coupling receptacle.

In particular, it can be provided that the coupling projection has an n-fold symmetry with respect to the axis of rotation and that the coupling receptacle has an m-n-fold symmetry with respect to the axis of rotation. Here, m and n are natural numbers greater than or equal to two.

In a particular exemplary embodiment, n = 4 and m = 2, so that in this case the coupling projection has a four-fold symmetry with respect to the axis of rotation and the coupling receptacle has an eight-fold symmetry with respect to the axis of rotation.

The coupling receptacle can be formed in one piece with a base body of the sieve element or in one piece with a base body of the sealing element. The coupling receptacle is preferably formed on a coupling element which is fixed on a base body of the sieve element or on a base body of the sealing element.

In particular, it can be provided that the coupling element is fixed to the base body by a press fit, by a material bond (for example by gluing or welding), by a positive fit (for example by locking) and / or by a force fit.

So that the user of the assembly can precisely control the transfer of the sealing element from the closed position to the open position and / or from the open position to the closed position by the movement of the sieve element generated by it, it is advantageous if the coupling projection during the transfer of the sealing element from the The closed position in the open position and / or during the transfer of the sealing element from the open position into the closed position is always in engagement with the coupling receptacle.

In principle, the coupling projection can be arranged on the sealing element or on the screen element and the coupling receptacle on the other element, that is to say on the screen element or on the sealing element.

In a preferred embodiment of the invention it is provided that the coupling projection is arranged on the sealing element and the coupling receptacle on the sieve element.

In order to be able to open or close the drain opening in a simple manner for the passage of liquid even after removal of the screen element from the drain cup, it is advantageous if the sealing element after removal of the screen element by rotating the coupling projection from the closed position into the open position and / or can be transferred from the open position to the closed position, the user preferably engaging the coupling projection with his hand. The sealing element can be lifted from the drain cup before the coupling projection is rotated and / or lowered onto the drain cup after the coupling projection has been rotated.

In this case, the coupling projection is preferably designed as a grip element on which the user can grip with his hand.

The coupling projection can also comprise a plurality of partial projections, for example each in the form of a pin, which, when the sieve element and the sealing element are coupled to one another, engage in a partial receptacle of a multi-part coupling receptacle, for example in the form of a slot in each case.

It can be provided that the partial projections on the sealing element and the partial receptacles are arranged on the sieve element, wherein in particular the partial receptacles can simultaneously serve as sieve openings of the sieve element.

A particularly positive appearance of the assembly results if the sieve element assumes essentially the same height position in the closed position of the sealing element and in the open position of the sealing element. In this way, it is avoided in particular that an annular gap is created between the sieve element and the drain cup in the open position of the sealing element, which is often perceived as unattractive, especially when it is not parallel to the contour.

On the other hand, it can be advantageous if the screen element changes its height position between the closed position and the open position at least temporarily when the sealing element is transferred from the closed position to the open position and / or when the sealing element is transferred from the open position to the closed position. Such a change in the height of the sieve element during the transfer process gives the user of the assembly which engages the sieve element haptic feedback about the transfer process of the sealing element.

It is preferably provided that the screen element is at least temporarily raised when the sealing element is transferred from the closed position to the open position and / or when the sealing element is transferred from the open position to the closed position.

In principle, the sealing element can be moved from the open position into the closed position by rotating the sieve element clockwise or counterclockwise.

Since the user is used to other things, for example when turning off a tap, when closing a bottle with a screw cap or when screwing a screw into a screw receptacle, that a closing process is carried out by turning it clockwise, it is advantageous if the sealing element can be transferred clockwise from the open position into the closed position by a rotary movement of the sieve element - seen from above in the plan view of the sieve element.

In a preferred embodiment of the invention it is provided that the actuating device comprises a control device which controls the height position of the sealing element during the transfer of the sealing element from the closed position to the open position and / or during the transfer of the sealing element from the open position to the closed position.

Such a control device can in particular comprise a control contour arranged on the sealing element on the sealing element side and / or a control contour arranged on the discharge cup on the discharge side.

In order to provide the user with reliable feedback about the reaching of the closed position, it is advantageous if the control device is designed in such a way that the movement of the sealing element from the open position into the closed position is stopped by a stop when the sealing element reaches the closed position.

Alternatively or in addition to this, it can also be provided that the control device is designed such that the movement of the sealing element from the closed position into the open position is stopped by a stop when the sealing element reaches the open position.

Alternatively, it could also be provided that there is no stop to limit the movement of the sealing element relative to the drain cup; In this case, the sealing element can be transferred from the open position to the closed position and from the closed position back to the open position by continuing the rotary movement of the sieve element without changing the direction of rotation.

For the information of the user about the transfer process, it is advantageous if the control device is designed in such a way that the sealing element is lifted from the drain cup while overcoming resistance, as soon as or after the movement of the sieve element, through which the sealing element moves from the closed position into the Open position is transferred, and / or as soon as or after the movement of the screen element begins, through which the sealing element is transferred from the open position to the closed position.

In particular, it can be provided that the resistance to be overcome by the user at the start of the transfer from the closed position to the open position differs from the resistance to be overcome by the user at the start of the transfer from the open position to the closed position.

In particular, it can be provided that the resistance to be overcome by the user at the start of the transfer of the sealing element from the closed position to the open position is lower than the resistance to be overcome by the user at the start of the transfer from the open position to the closed position.

A particularly favorable optical impression of the assembly results when the assembly is in operation if the sieve element comprises an integrally formed base body which essentially forms the entire visible side of the sieve element facing the user of the assembly during operation of the assembly.

• ein Ventilunterteil, vorzugsweise mit einem Abgangsbogen;
• ein Ventiloberteil, vorzugsweise mit einem Überlaufanschluss und/oder einer Dichtung;
• einen Ablaufkelch, der eine Ablauföffnung, die vorzugsweise mehrere Ablauflöcher umfasst, und/oder eine, beispielsweise eingeprägte, ablaufseitige Steuerkontur aufweisen kann; und
• ein Führungselement, beispielsweise in Form einer Führungshülse, zur Führung eines Führungsstiftes, der an dem Abdichtelement vorgesehen sein kann.

The assembly according to the invention can be part of a drain arrangement for the basin, which can comprise one or more of the following components in addition to the sieve element and the sealing element:

• a valve lower part, preferably with an outlet bend;
• an upper valve part, preferably with an overflow connection and / or a seal;
• a drain cup, which may have a drain opening, which preferably comprises a plurality of drain holes, and / or a control contour, for example an embossed drain drain; and
• a guide element, for example in the form of a guide sleeve, for guiding a guide pin, which can be provided on the sealing element.

The guide element can be designed, for example, as a hollow screw.

A head of the guide element can be received in a recess of the drain cup so that it does not protrude above the top of the area of the drain cup adjacent to the recess, preferably an upper face of the head being substantially flush with the top of the area of the drain cup adjacent to the recess is arranged. This simplifies the cleaning of the drain arrangement.

The guide pin of the sealing element can preferably be inserted into the guide element.

The sieve element is preferably centered in relation to the sealing element by the coupling between the coupling receptacle and the coupling projection.

The sealing element is preferably centered by the engagement of the guide pin in the guide element with respect to the guide element and with respect to the drain cup.

The sieve element can have an edge section, the outside diameter of which is matched to the outside diameter of the drain cup and is preferably essentially the same size as or larger than the outside diameter of the drain cup.

An outer edge of the sieve element can be provided with a flange or a bevel, which bears against an outer edge of the drainage cup, whereby the sieve element can also be centered on the drainage cup when the sealing element has been removed from the drainage cup.

Furthermore, the drain arrangement can also comprise a lifting device, by means of which the sealing element can be transferred from the closed position into a raised position, in which the sealing element allows a liquid to drain out of the basin through the drain opening without the sieve element being moved. Such a lifting device can comprise, for example, an actuation switch arranged on the basin, a cable pull and a lever unit acting on a lower end of the guide pin of the sealing element.

Since the sealing element and the sieve element can be completely detached from one another in the assembly according to the invention, the assembly can be used without the sealing element for a non-closable outlet and thus take over the function of an overflow, for example in a two-bowl sink without an additional overflow.

The drain opening on the drain cup preferably has a harmonious hole pattern that is easy to clean.

The sieve element preferably completely covers the outer edge of the goblet when it is placed on the goblet, so that the user has a clean visual impression.

The sieve element preferably comprises a one-piece base body, which can be produced, for example, by a deep-drawing process.

A coupling element, which is provided with the coupling receptacle or with the coupling projection, is preferably pressed into the base body of the sieve element and / or mechanically fixed to the base body and / or glued to the base body in order to absorb and apply torque generated by the user to the base body to be able to pass on the sealing element.

The assembly according to the invention is particularly suitable for use on a basin of a sink, in particular a kitchen sink.

The material of the sink can in principle be of any type and in particular comprise a stainless steel material, a composite material and / or a ceramic material.

The sieve element and / or the drain cup are preferably arranged in the basin such that an edge section of the sieve element and / or an edge section of the drain cup is arranged essentially flush with an adjacent area of the pelvic floor.

By separating the screen element and the sealing element, actuation of the sealing element is fundamentally possible in the assembly according to the invention without changing the height position of the screen element.

By eliminating an annular gap between the sieve element and the drain cup, no food residues can inadvertently reach the drain opening between the drain cup and the sieve element.

The appearance of the assembly is the same in the closed position and in the open position of the sealing element.

Since the sealing element and the sieve element can be easily detached from one another, both elements can be cleaned independently of one another, for example in a dishwasher.

The coupling element with the coupling receptacle can be fixed to the base body of the sieve element directly or by means of a sleeve in which the coupling element is arranged.

Such a sleeve can be formed, for example, from a metallic material, for example from a stainless steel material.

The coupling element can be connected to the sleeve by a press fit, by a form fit and / or by a material fit.

The coupling projection and / or the coupling receptacle can have rounded edges and / or corners.

One in the Fig. 1 . 2 and 17 Drain arrangement 100 shown as a whole for arrangement on the pool floor of a (not shown) sink, in particular a sink of a sink, preferably a kitchen sink, comprises a drain fitting 102 with a drain cup 104, an upper valve part 106, which is preferably provided with a seal 108 and an overflow connection 110 and a valve lower part 112, which is preferably provided with an outlet bend 114, and a guide element 115, which is designed, for example, as a guide sleeve 116 and preferably in the form of a hollow screw 118, and by means of which the drain cup 104, the valve lower part 112 and the valve upper part located therebetween 106 are screwed together.

The drain arrangement 100 further comprises an assembly 120 for closing a drain opening 122 of the basin, which is arranged on the drain cup 104.

This assembly 120 comprises a sieve element 124 with one or more sieve openings 126 and a sealing element 128 with a sealing element 130 which, in a closed position of the sealing element 128, lies sealingly against the drainage cup 104, so that no liquid can get out of the basin through the outlet opening 122, and that in an open position allows a liquid to drain from the basin through the drain opening.

The sieve element 124 of the assembly 120 is shown separately in FIGS 3 to 8 shown.

How best to look Fig. 4 can be seen, the sieve element 124 comprises a, preferably integrally formed, base body 132 and a coupling element 134 fixed to an underside of the base body 132.

The base body 132 comprises a handle section 136 arranged essentially centrally on the sieve element 124, with a cover section 138, for example essentially circular, which is bordered by a side wall section 140 projecting downward from the outer edge of the cover section 138.

The side wall section 140 is preferably concavely curved — viewed from the top side of the sieve element 124 facing the user of the basin in the assembled state of the drain arrangement 100 — and has, for example, a substantially C-shaped cross section.

A sieve bottom section 142 of the base body 132 adjoins a lower outer edge of the side wall section 140, which surrounds the handle section 136 in a ring shape and is designed, for example, to rise radially outward, in particular in the form of a bowl or bowl.

The one or more sieve openings 126, for example extending in the radial direction 144 of the sieve element 124, are arranged in the sieve bottom section 142.

The sieve openings 126 follow one another in the circumferential direction of the sieve element 124 and are spaced apart from one another in the circumferential direction, preferably essentially equidistantly.

The sieve bottom section 142 of the sieve element 124 is adjoined on the outside by an edge section 148 of the base body 132 which surrounds the sieve bottom section 142 in a ring, the radial cross section of which is shown in FIG Fig. 5 is shown enlarged.

The edge section 148 can in particular comprise a substantially horizontal area 150 which adjoins the sieve bottom section 142, and an edge area 151 which adjoins the horizontal area 150 on the outside and which is bent downwards with respect to the horizontal area 150.

The base body 132 of the sieve element 124 is preferably designed as a sheet metal part.

The base body 132 is preferably formed from a metallic material, in particular from a stainless steel material.

The coupling element 134 of the screen element 124 is connected on the underside of the grip section 136 of the base body 132 in a rotationally fixed manner to the base body 132, for example by press fitting, gluing and / or latching.

How best from the 6 and 7 can be seen, which represent the coupling element 134 separately, the coupling element 134 can be substantially cylindrical. A coupling receptacle 152 is provided on an underside of the coupling element 134 facing away from the base body 132, into which a coupling projection 154 of the sealing element 128 can engage when the assembly 120 is in the operating state (see FIG 8 to 10 ).

How out Fig. 9 can be seen, the coupling projection 154 of the sealing element 128 has a common central axis of rotation with respect to a longitudinal central axis 156 of the sealing element 128 which is oriented vertically in the operating state of the assembly 120 and which is arranged coaxially with a longitudinal central axis 158 of the sieve element 124 and a common axis of rotation 160 of the sealing element 128 and the sieve element 124, about which the sieve element 124 and the sealing element 128 can be rotated together, form an n-fold symmetry, where n is a natural number greater than or equal to two.

In the exemplary embodiment shown in the figures, n = 4, so that the coupling projection 154 has a four-fold symmetry with respect to the axis of rotation 160, in which the outer contour of the coupling projection 154 can be converted into itself by rotating about the axis of rotation 160 by 90 °.

In principle, it would suffice for the coupling of the sealing element 128 to the sieve element 124 if the coupling receptacle 152 of the coupling element 134 on the sieve element 124 also had an n-fold symmetry with respect to the longitudinal central axis 158 of the sieve element 124, which also forms the axis of rotation 160 ,

In order to facilitate the insertion of the coupling projection 154 into the coupling receptacle 152, however, it is preferably provided that the coupling receptacle 152 has symmetry with respect to the axis of rotation 160, where m is a natural number greater than or equal to two.

In the exemplary embodiment shown in the drawings, m = 2, so that in the event of a four-fold symmetry of the coupling projection 154 with respect to the axis of rotation 160, the coupling receptacle 152 has an eight-fold symmetry with respect to the axis of rotation 160 and the outer contour of the coupling receptacle 152 by a rotation about the axis of rotation 160 is 45 ° convertible in itself.

The insertion of the coupling projection 154 into the coupling receptacle 152 can therefore take place in m · n different angular positions of the coupling projection 154 relative to the coupling receptacle 152, which have an angular distance of 360 ° / (m. N) with respect to the axis of rotation; In the exemplary embodiment shown in the drawings, the insertion of the coupling projection 154 into the coupling receptacle 152 can thus take place in eight different angular positions of the coupling projection 154 relative to the coupling receptacle 152, the angular distance of which in relation to the axis of rotation 160 is 45 ° in each case.

The coupling projection 154 can have n, preferably rounded, corner regions 162 which, in the coupled state of the sealing element 128 and the sieve element 124, each engage in a bulge 164 of the coupling receptacle 152 which is complementary thereto, so that in the coupled state n bulges 164 of the total of n bulges the coupling receptacle 152 are occupied by corner regions 162 of the coupling projection 154 and the remaining bulges 164 of the coupling receptacle 152 remain free.

How best to look Fig. 6 can be seen, the coupling element 134 can be provided on the outside of its peripheral wall 166, which surrounds the coupling receptacle 152, with one or more latching lugs 168 which, in the assembled state of the sieve element 124, extend the most protruding area of the longitudinal central axis 158 of the sieve element 124 Reach behind the side wall section 140 of the base body 132, so that the coupling element 134 is held on the base body 132 by positive locking.

The coupling element 134 is preferably made of a plastic material and, for example, in an injection molding process.

The coupling element 134 with the coupling receptacle 152 and the coupling projection 154 form components of a coupling device 155, by means of which the sieve element 124 and the sealing element 128 are coupled to one another in such a way that a rotational movement of the sieve element 124 about the axis of rotation 160 a rotational movement of the sealing element 128 about the same axis of rotation 160 causes.

The coupling between the screen element 124 and the sealing element 128 is such that the screen element 124 and the sealing element 128 are movable relative to one another in a height direction 157.

The height direction 157 is preferably aligned parallel to the axis of rotation 160 about which the sieve element 124 and the sealing element 128 can be rotated.

The sealing element 128 is in the 8 to 10 Shown separately and comprises a base plate 170, preferably of substantially circular disc shape, from the top of which the coupling projection 154 extends upwards, in the coupled state of the assembly 120, towards the sieve element 124.

The, for example essentially cuboid, coupling projection 154 with its preferably rounded corner regions 162 and a preferably convexly curved upper side 171 can be provided with one or more indentations 174, preferably on its side walls 172 extending parallel to the direction of the longitudinal central axis 156 of the sealing element 128, which make it easier for a user to grip the coupling projection 154 with his fingers and to rotate the sealing element 128 directly, without the interposition of the sieve element 124, about the axis of rotation 160 when the sieve element 124 has been removed from the drain cup 104 and decoupled from the sealing element 128 ,

The indentations 174 further facilitate the lifting of the sealing element 128 from the drain cup 104.

As best seen from the sectional view of Fig. 10 can be seen, the base plate 170 has a radially outer, preferably thickened, edge section 176, to which the sealing element 130, which preferably surrounds the base plate 170 in an annular manner, is fixed.

In order to fix the sealing element 130 to the base plate 170 of the sealing element 128, it can be provided in particular that the base plate 170 has an annular groove 178 on its outer edge, in which a radially inner base section 180 of the sealing element 130 is received and, for example, by press fit, adhesive bonding and / or locked.

A sealing lip 182 of the sealing element 130 extends radially outward and preferably downward from the base section 180 to a bottom 184 of the drainage cup 104.

Furthermore, the base plate 170 of the sealing element 128 carries at least one control element 186, preferably two or more control elements 186, on its underside, preferably near its outer edge, in the embodiment shown in the drawings three control elements 186.

The control elements 186 are preferably spaced apart from one another in the circumferential direction of the sealing element, for example equidistantly.

Each of the control elements 186 carries at its lower end a control projection 188 which is arranged on an edge of the control element 186 which is in the counterclockwise direction, as seen from above in the top view of the sealing element 128, and a stop projection 190, which on one - in the Top view seen from above on the sealing element 128 - counterclockwise rear edge of the control element 186 is arranged.

The control projection 188 and the stop projection 190 are separated from one another by an intermediate recess 192.

The stop projection 190 preferably extends further downward along the longitudinal central axis 156 of the sealing element 128, that is to say away from the coupling projection 154 than the control projection 188.

A front edge 194 of the stop projection 190 facing the control projection 188 runs essentially parallel to the longitudinal central axis 156 of the sealing element 128 or is inclined with respect to the direction of the longitudinal central axis 156 by a small acute angle of less than 30 °, preferably less than 10 °.

A rear edge 196 of the stop projection 190 facing away from the control projection 188 runs essentially parallel to the longitudinal central axis 156 of the sealing element 128 or is inclined at a small acute angle of less than 30 °, preferably of less than 10 °, with respect to the direction of the longitudinal central axis 156.

A front edge 198 of the control projection 188 facing away from the stop projection 190 is inclined relative to the direction of the longitudinal central axis 156 of the sealing element 128 by an angle α in the range from approximately 30 ° to approximately 70 °, for example by an angle of approximately 50 °.

A rear edge 200 of the control projection 188 facing the stop projection 190 is inclined relative to the direction of the longitudinal central axis 156 of the sealing element 128 by an angle β of approximately 30 ° to approximately 70 °, for example approximately 40 °.

Preferably, the angle of inclination α of the front edge 198 of the control projection 188 is greater than the angle of inclination β of the rear edge 200 of the control projection 188, which has the consequence that when the sealing element 128 moves in the opening direction, that is to say at the start of the transfer of the sealing element 128 from the closed position to the open position, the user has to overcome a smaller resistance to lifting the sealing element 128 than when the sealing element 128 moves in the closing direction, that is to say at the beginning of the transfer of the sealing element 128 from the open position to the closed position.

In principle, however, the two inclination angles α and β can also be chosen to be the same size, or the inclination angle β of the rear edge 200 of the control projection 188 can be selected to be greater than the inclination angle α of the front edge 198 of the control projection 188.

The lower edge of the control element 186, which includes the front edge 198 of the control projection 188, a lower edge 202 of the control projection 188, the rear edge 200 of the control projection 188, an upper edge 204 of the recess 192, the front edge 194 of the stop projection 190, a lower Edge 206 of the stop projection 190 and the rear edge 196 of the stop projection 190 forms a control contour 208 on the sealing element side, which forms a control device 212 with a control contour 210 on the outlet side to be described later, which controls the height position of the sealing element 128 during the transfer of the sealing element 128 from the Controls the closed position into the open position and / or during the transfer of the sealing element 128 from the open position into the closed position.

The sealing element 128 further comprises a guide pin 214, which extends downward from the underside of the base plate 170 of the sealing element 128 along the longitudinal central axis 156 of the sealing element 128.

The guide pin 214 is preferably essentially cylindrical.

The guide pin 214 can be provided with a chamfer 218 at its lower end.

In the assembled state of the drain assembly 100, the guide pin 214 engages in the interior of FIG Fig. 11 separately shown guide sleeve 116 and is thus displaceably guided on the guide sleeve 116 in the direction of a longitudinal central axis 220 of the guide sleeve 116, which is arranged coaxially to the longitudinal central axis 156 of the sealing element 128 in the operating state of the drain arrangement 100.

The base plate 170, the guide pin 214 and the coupling projection 154 preferably form an integral base body 222 of the sealing element 128.

The base body 222 of the sealing element 128 is preferably formed from a plastic material and can in particular be designed as an injection molded part.

The sealing element 130 of the sealing element 128 is preferably formed from an elastomeric plastic material, in particular from a silicone material.

The drain cup 104 of the drain fitting 102 is shown separately in FIGS 12 to 14 shown.

The drain cup 104 is essentially funnel-shaped or bowl-shaped and comprises a bottom section 224, a side wall section 226 surrounding the bottom section 224 in an annular manner and an edge section 228 annularly surrounding the side wall section 226.

How best from the 18 to 21 can be seen, in the operating state of the drain arrangement 100, the screen element 124 rests on the edge section 228 of the drain cup 104, preferably on an inner edge of the edge section 228 (with the screen bottom section 142 of the screen element 124) and / or on an outer edge of the edge section 228 (with the edge section 148 of the sieve element 124).

The bottom portion 224 of the drain cup 104 has a central recess 230 in which a passage opening 232 for the passage of a shaft 234 of the guide element 115, for example in the form of the guide sleeve 116 (see Fig. 11 ), is provided.

The guide sleeve 116 has a head 236, which has an outer diameter that exceeds the outer diameter of the shaft 234 and the outer diameter of the passage opening 232.

The dimensions of the head 236 of the guide sleeve 116 and the recess 230 are coordinated with one another such that in the assembled state of the drain arrangement 100 the head 236 is completely accommodated in the recess 230 and not over the upper side 238 of the region of the base section 224 adjoining the recess 230 of the goblet 104 protrudes upwards (see in particular the 18 to 20 ).

In particular, it can be provided that an upper side 240 of the head 236 of the guide sleeve 116 facing away from the shaft 234 is arranged substantially flush with the upper side 238 of the region of the bottom section 224 of the drainage cup 104 adjoining the depression 230.

This enables particularly easy cleaning of the bottom area of the drain bowl 104, including the guide sleeve 116.

In the region of the bottom portion 224 of the drainage cup 104 surrounding the recess 230, the multi-part drainage opening 122 is formed, which comprises a plurality of drainage holes 242 which follow one another in the circumferential direction of the drainage cup 104 in the exemplary embodiment shown in the drawings.

The drain holes 242 are preferably arranged equidistantly from one another along the circumferential direction of the drain cup 104.

In each case two successive drain holes 242 in the circumferential direction of the drain cup 104 are separated from one another by a web 244 running in the radial direction of the drain cup 104.

One or more drain holes 242a, three such drain holes 242a in the exemplary embodiment shown in the drawings, have a larger passage area than a respectively adjacent drain hole 242b.

The passage area of the adjacent drain hole 242b is reduced in particular by a support bar 246, which preferably extends on the radially outer edge of the drain hole 242b between the two webs 244 laterally delimiting the drain hole 242b.

In the operating state of the drain arrangement 100, an upper side 248 of the support bar 246 lies lower than an upper side 250 of the web 244, which separates the drain hole 242b from the adjacent larger drain hole 242a.

The support bar 246, which is lowered relative to the adjacent web 244, can be introduced into the bottom portion 224 of the drain cup 104 in particular by an embossing process.

The top 248 of the support bar 246, a front edge 252 of the web 244 facing the support bar 246, the top 250 of the web 244 and a rear edge 254 of the web 244 facing away from the support bar 246 together form the above-mentioned run-side control contour 210, which with the Control contour 208 on the sealing element side cooperates with one of the control elements 186 of the sealing element 128 such that the height position of the sealing element 128 during the transfer of the sealing element 128 from the closed position into the open position and / or during the transfer of the sealing element 128 from the open position into the closed position in FIG is controlled in more detail below.

The drain cup 104 may comprise a metallic material and / or a plastic material.

Preferably, the goblet 104 is formed essentially entirely from a metallic material or from a plastic material.

The drain cup 104 can be inserted into an opening in the pool floor of the pool on which the drain arrangement 100 is arranged.

As an alternative to this, it can also be provided that the drain cup 104 is formed in one piece with the pelvic floor.

This in Fig. 15 Separately shown valve upper part 106 comprises a bowl-shaped main body 256, which surrounds the drain cup 104 in the assembled state of the drain arrangement 100 (see Fig. 17 ) and sealingly rests on its upper edge via the seal 108 on the underside of the edge section 228 of the drain cup 104 and / or on the underside of the pelvic floor.

The tubular overflow connection 110 opens into a side wall 258 of the main body 256, via which an overflow arrangement (not shown) of the basin on which the drain arrangement 100 is arranged, or a drain or an overflow of another basin, can be connected to the drain arrangement 100 such that Liquid from the relevant overflow or drain reaches the interior of the main body 256.

The overflow connection 110 is preferably not arranged radially but, for example, tangentially on the main body 256. As a result, the overflow water is introduced eccentrically into the main body 256, which improves the drainage behavior and the overflow performance.

The cross section of the tubular overflow connection 110 can in principle have any shape and, for example, be essentially circular, oval or angular.

The end of the overflow connection 110 facing away from the main body 256 is in the delivery state of the sequence arrangement 100 or in the operating state of the sequence arrangement 100, if no other overflow or sequence is to be connected to the sequence arrangement 100, by means of the in FIG 21 to 23 separately shown sealing plug 260 can be closed.

The sealing plug 260 comprises a substantially hollow cylindrical section 262, the outer diameter of which corresponds essentially to the inner diameter of the overflow connection 110, so that the sealing plug 260 can be inserted in a sealing manner in the end region of the overflow connection 110.

The fluid-tight seal between the sealing plug 260 and the overflow connection 110 can be provided by a seal (not shown) which is molded onto the inside of the overflow connection 110, for example injection molded, or is inserted or inserted into the overflow connection 110.

Alternatively or in addition to this, the sealing plug 260 could also be provided with a seal on its outside.

Such a seal on the overflow connection 110 or on the sealing plug 260 can comprise, for example, an O-ring and / or a sealing sleeve and can be formed, for example, from a soft material or from a two-component material.

The end of the hollow cylindrical section 262 facing away from the valve lower part 112 in the inserted state of the sealing plug 260 is provided with a flange region 264 which projects radially outwards.

When inserting the sealing plug 260 into the overflow connection 110, the flange region 264 serves as a stop, which limits the insertion path of the sealing plug 260 in the longitudinal direction of the overflow connection 110.

The end of the hollow cylindrical section 262 facing away from the flange region 264 is closed by an end wall 266.

The sealing plug 260 further comprises a tool section 268, which, during assembly or disassembly of the drain arrangement, for connecting the guide sleeve 116 to the in Fig. 16 separately shown lower valve part 112 can be used.

For this purpose, the tool section 268 can in particular have an outer contour which is complementary to an actuating section 269 of the guide element 115 in the form of an actuating recess 270 on the head 236 of the guide sleeve 116, so that the tool section 268 is brought into engagement with the actuating recess 270 and then the guide sleeve 116 can be rotated about the longitudinal central axis 220 of the guide sleeve 116 by rotating the sealing plug 260 about its longitudinal central axis 272.

In particular, it can be provided that the tool section 268 has a polygonal, for example hexagonal, cross section, taken perpendicular to the longitudinal central axis 272 of the sealing plug 260, and that the actuating recess 270 of the guide sleeve 116 has a polygonal, complementary thereto, taken perpendicular to the longitudinal central axis 220 of the guide sleeve 116. for example hexagonal, cross-section.

How best from the Fig. 21 and 22 can be seen, the tool section 268 is preferably connected via a support structure 274 to the hollow cylindrical section 262 and / or to the flange region 264 of the sealing plug 260 and is held essentially coaxially with the longitudinal central axis 272 of the sealing plug 260.

The support structure 274 can comprise a plurality of, for example six, ribs 276, preferably running radially to the longitudinal central axis 272 of the sealing plug 260.

The tool section 268 can also be provided with a recess 278, which preferably corresponds in terms of its shape to the outer contour of the tool section 268, but has smaller dimensions.

The sealing plug 260 including the hollow cylindrical section 262, the flange area 264, the end wall 266, the support structure 274 and the tool section 268 is preferably formed as an integral part.

The sealing plug 260 preferably comprises a plastic material. In particular, it can be provided that the sealing plug 260 is formed essentially entirely from a plastic material and is produced, for example, as an injection molded part.

As an alternative to an upper valve part 106 with an overflow connection 110, an upper valve part without an overflow connection can also be used.

How best to look Fig. 17 It can be seen that the valve upper part 106 has a through opening 280 on its underside, which is surrounded by an annular flange section 282 and, in the assembled state of the drain arrangement 100, engages with a flange section 284 of the valve bottom part 112 that is complementary thereto in such a way that the through opening 280 of the upper valve part 106 opens into an interior 286 of the lower valve part 112. As a result, liquid running out of the basin through the outlet opening 122 and / or liquid running out through the overflow connection 110 can reach the interior 286 of the lower valve part 112.

A sealing ring 288 arranged between them serves to seal between the flange section 282 of the upper valve part 106 and the flange section 284 of the lower valve part 112.

From the interior 286 of the lower valve part 112, the draining liquid passes through the outlet bend 114 serving as a draining line 299 into a liquid discharge line (not shown) and finally into the sewage system.

The outlet arch 114 can have a gradient, for example a gradient of at least approximately 1% and / or at most approximately 3%, in particular approximately 2%, in order to improve the drainage performance and to avoid the formation of deposits.

The lower valve part 112 further comprises an anchoring element 290, in which a lower end of the guide sleeve 116 can be anchored.

The anchoring element 290 is, for example, essentially hollow-cylindrical and is preferably provided with an internal thread 292 into which an external thread 294 on the shaft 234 of the guide sleeve 116 (see Fig. 11 ) can be screwed in to clamp the drainage cup 104, which the head 236 of the guide sleeve 116 engages behind, the valve lower part 112 and the valve upper part 106 arranged between the drainage cup 104 and the valve lower part 112.

The anchoring element 290 can be held on a side wall 298 of the lower valve part 112 via a support structure 296, and preferably in such a way that a longitudinal central axis of the anchoring element 290 is arranged coaxially with the longitudinal central axis 220 of the guide sleeve 116.

The support structure 296 can in particular comprise a plurality of ribs 300, which are preferably radially oriented with respect to the longitudinal center axis of the anchoring element 290.

The lower valve part 112 and / or the upper valve part 106 preferably comprise a plastic material. In particular, it can be provided that the lower valve part 112 and / or the upper valve part 106 is formed essentially entirely from a plastic material and is produced, for example, as an injection molded part.

When assembling the drain arrangement 100 described above on a basin, in particular on a sink of a kitchen sink, the procedure is as follows:
The drain cup 104 is hung from above into an associated opening on the pool floor. The upper valve part 106 and the lower valve part 112 are joined together and applied with the seal 108 on the upper edge of the upper valve part 106 to the drainage cup 104 and the pelvic floor from below.

The shaft 234 of the guide sleeve 116 is inserted through the passage opening 232 in the recess 230 of the bottom section 224 of the drain cup 104 into the anchoring element 290 of the valve lower part 112 and using the tool section 268 of the sealing plug 260, which engages with the actuating recess 270 of the guide sleeve 116 is brought, screwed into the internal thread of the anchoring element 290 by turning the sealing plug 260 until the drain cup 104, the valve lower part 112 and the intermediate valve upper part 106 are clamped together and the head 236 of the guide sleeve 116 is completely received in the recess 230 of the drain cup 104 (please refer Fig. 17 ).

The sealing plug 260 thus serves as an assembly component 303 of the assembly 120, which can be used during assembly of the assembly 120 for mounting the guide element 115 in the form of the guide sleeve 116 on the valve lower part 112 serving as an anchoring component 305.

The sealing plug 260 can be arranged on the overflow connection 110 of the valve upper part 106 after the assembly of the guide sleeve 116. The upper valve part 106 thus serves as a receiving component 307, on which the mounting component 303 can be arranged when the assembly 120 is in the assembled state.

The sealing element 128 is inserted into the drain cup 104 such that the guide pin 214 engages in the interior of the guide sleeve 116 and the control elements 186 each engage in one of the larger drain holes 242a.

Thus, the sealing element 128 is in its in the 18 and 19 Shown closed position, in which the sealing element 130 rests with its sealing lip 182 sealingly against the bottom portion 224 of the drain cup 104 and thus prevents liquid from flowing out of the drain cup 104 through the drain opening 122.

The extent of each control element 186 on the sealing element 128 along the circumferential direction of the sealing element 128 is preferably dimensioned such that in the in the 18 and 19 shown closed position of the sealing element 128, the front edge 198 of the control projection 188 bears against the rear edge 254 of the web 244 lying in front of the control projection 188 in question, viewed from above in the counterclockwise direction, and that the rear edge 196 of the stop projection 190 of the same control element 186 rests on the front Edge 252 of the web 244 lying behind the relevant control element 186, as seen from above in the counterclockwise direction.

As a result, the sealing element 128 is centered with respect to the drain cup 104 such that the longitudinal central axis 156 of the sealing element 128 coincides with the longitudinal central axis 220 of the guide sleeve 116.

Furthermore, due to the engagement of the control elements 186 in the drain holes 242a of the drain opening 122, the angular position of the sealing element 128 relative to the drain cup 104 is fixed in such a way that it is only counterclockwise by rotating the sealing element 128, as seen from above, while overcoming one Resistance that is required to lift the sealing member 128 is variable.

The sieve element 124 is placed in a working position on the drain cup 104 in such a way that the coupling projection 154 of the sealing element 128 engages in the coupling receptacle 152 of the sieve element 124.

This engagement is retained even when the sealing element 128 and the sieve element 124 are rotated, so that the sealing element 128 is coupled to the sieve element 124 in a rotationally fixed manner.

So that is in the 17 to 19 The final assembly state of the drain assembly 100 shown is reached, the sealing element 128 initially being in the closed position.

To transfer the sealing element 128 from the in the 18 and 19 shown closed position in the in Fig. 20 The open position shown is carried out as follows:
A user of the basin on which the drain assembly 100 is arranged grips the handle portion 136 of the sieve element 124 with his hand and rotates it (viewed from above) counterclockwise.

Due to the coupling of the sealing element 128 to the sieve element 124 by means of the coupling device 155, the sealing element 128 follows this rotational movement of the sieve element 124, as a result of which the front edges 198 of the control projections 188 of the control elements 186 of the sealing element 128 on the rear edge 254 of the respectively adjacent web 244 upwards slide, whereby the sealing element 128 is lifted vertically upwards until the lower edges 202 of the control projections 188 reach the level of the upper side 250 of the respectively adjacent web 244.

In this intermediate position between the closed position and the open position, the sealing element 128 has reached its highest position.

It can be provided that the sealing element 128 is raised so much during the transition from the closed position to this intermediate position that the coupling projection 154 reaches the upper end of the coupling receptacle 152 and raises the sieve element 124, preferably a short distance, from the drain cup 104, which provides the user with haptic feedback that the intermediate position has been reached.

By turning the sieve element 124 and the sealing element 128 coupled thereto beyond this intermediate position, the control projections 188 slide over the respectively assigned webs 244 until the rear edges 200 of the control projections 188 slide down on the front edge 252 of the respectively assigned web 244, as a result of which the sealing element 128 is lowered again in the vertical direction until the in Fig. 20 Open position of the sealing element 128 shown is reached, in which the upper edges 204 of the recesses 192 of the control elements 186 abut the top 250 of the respectively assigned web 244 and the front edges 194 of the stop projections 190 rest against the rear edge 254 of the respectively assigned web 244 and in each case form a stop 302 which prevents the rotational movement from continuing beyond the closed position.

How out Fig. 20 can be seen, in the open position of the sealing element 128, the sealing lip 182 of the sealing element 130 is spaced from the bottom portion 224 of the drain cup 104 in the vertical direction, so that liquid can drain out of the drain cup 104 through the drain opening 122.

To remove the sealing element 128 from the in Fig. 20 shown open position again in the in the 18 and 19 To move the illustrated closed position back, the user again engages with his hand on the grip section 136 of the sieve element 124 and rotates it clockwise, viewed from above, whereby the rear edges 200 of the control projections 188 follow along the front edge 252 of the respectively assigned web 244 Slide up until the intermediate position of the sealing element 124 is reached, in which the sieve element 124 is preferably lifted off the drain cup 104.

Since the control projections 188 are asymmetrical and in particular the angle β, at which the rear edge 200 of the control projection 188 is inclined with respect to the direction of the longitudinal central axis 156 of the sealing element 128, is smaller than the angle a, at which the front edge 198 of the control projection 188 is inclined with respect to the direction of the longitudinal central axis 156 of the sealing element 128, the initial resistance which the user must overcome at the beginning of the transfer of the sealing element 128 from the open position into the closed position is greater than the initial resistance which the user has at the beginning of the transfer of the sealing element 128 must overcome from the closed position to the open position.

After reaching the intermediate position, continued rotation - seen from above - clockwise, the lower edges 202 of the control projections 188 slide along the top 250 of the respectively associated web 244 until finally the front edges 198 of the control projections 188 on the rear edge 254 of the each associated web 244 after slide down, whereby the sealing element 128 is lowered vertically downwards until the rear edges 196 of the stop projections 190 bear against the front edge 252 of the respectively adjacent web 144 and thus form a stop 304, which further moves the sieve element 124 and the sealing element coupled to it 128 prevented in the closing direction.

This is the in again Fig. 20 shown closed position of the sealing element 128 reached.

The coupling device 155 comprising the coupling projection 154 and the coupling receptacle 152 and the control device 212 comprising the sealing element-side control contour 208 and the outlet-side control contour 210 thus form components of an actuating device 301, by means of which the sealing element 128 is generated by a movement of the sealing element 124 by the user by engaging the sieve element 124 Sieve elements 124 can be transferred from the closed position into the open position and from the open position into the closed position.

In the drain arrangement 100 described above, it is also possible to remove the screen element 124 completely upward from the drain cup 104 and to release it from the coupling with the sealing element 128.

After the sieve element 124 has been removed, the user of the basin on which the drain arrangement 100 is arranged can directly engage the coupling projection 154 of the sealing element 128 in order to move the sealing element 128 in the opening direction (in particular - viewed from above - counterclockwise) or in the closing direction (in particular - seen from above - clockwise) and thus move the sealing element 128 without the interposition of the sieve element 124 from the closed position to the open position or from the open position to the closed position.

One in the 24 to 47 The illustrated second embodiment of a drain arrangement 100 for arrangement on the pelvic floor of a basin, in particular a basin of a sink, preferably a kitchen sink, differs from that in FIGS 1 to 23 First embodiment shown in particular in that none of the drain holes 242 of the multi-part drain opening 122 of the drain cup 104 has a passage area reduced by a support strip 246, but rather all drain holes 242 have an equally large passage area.

In this second embodiment, therefore, only the front edge 252 of the web 244 between two mutually adjacent drain holes 242, the top side 250 of the web 244 and a rear edge 254 of the web 244 together form the drain-side control contour 210, which with the sealing-element-side control contour 208 is in each case one of the control elements 186 of the sealing element 128 cooperates in such a way that the height position of the sealing element 128 is controlled during the transfer of the sealing element 128 from the closed position into the open position and / or during the transfer of the sealing element 128 from the open position into the closed position.

This control is carried out during the transfer of the sealing element 128 from the into the 41 and 42 shown closed position in the in Fig. 43 shown open position carried out as follows:
A user of the basin on which the drain assembly 100 is arranged grips the handle portion 136 of the sieve element 124 with his hand and rotates it (viewed from above) counterclockwise.

Due to the coupling of the sealing element 128 to the sieve element 124 by means of the coupling device 155, the sealing element 128 follows this rotational movement of the sieve element 124, as a result of which the front edges 198 of the control projections 188 of the control elements 186 of the sealing element 128 slide up the rear edge 254 of the respective adjacent web 244, whereby the sealing element 128 is lifted vertically upwards until the lower edges 202 of the control projections 188 reach the level of the upper side 250 of the respectively adjacent web 244.

In this intermediate position between the closed position and the open position, the sealing element 128 has reached its highest position.

It can be provided that the sealing element 128 is raised so much during the transition from the closed position to this intermediate position that the coupling projection 154 reaches the upper end of the coupling receptacle 152 and raises the sieve element 124, preferably a short distance, from the drain cup 104, which provides the user with haptic feedback that the intermediate position has been reached.

By turning the sieve element 124 and the sealing element 128 coupled thereto beyond this intermediate position, the control projections 188 slide over the respectively assigned webs 244 until the rear edges 200 of the control projections 188 slide down on the front edge 252 of the respectively assigned web 244, as a result of which the sealing element 128 is lowered again in the vertical direction until the in Fig. 43 Open position of the sealing element 128 shown is reached, in which the upper edges 204 of the recesses 192 of the control elements 186 abut the top 250 of the respectively assigned web 244 and the front edges 194 of the stop projections 190 rest against the rear edge 254 of the respectively assigned web 244 and in each case form the stop 302, which prevents the rotational movement from continuing beyond the closed position.

How out Fig. 43 can be seen, in the open position of the sealing element 128, the sealing lip 182 of the sealing element 130 is spaced from the bottom portion 224 of the drain cup 104 in the vertical direction, so that liquid can drain out of the drain cup 104 through the drain opening 122.

To remove the sealing element 128 from the in Fig. 43 shown open position again in the in the 41 and 42 To move the illustrated closed position back, the user again engages with his hand on the grip section 136 of the sieve element 124 and rotates it clockwise, viewed from above, whereby the rear edges 200 of the control projections 188 follow along the front edge 252 of the respectively assigned web 244 Slide up until the intermediate position of the sealing element 124 is reached, in which the sieve element 124 is preferably lifted off the drain cup 104.

Since the control projections 188 are asymmetrical and in particular the angle β, at which the rear edge 200 of the control projection 188 is inclined with respect to the direction of the longitudinal central axis 156 of the sealing element 128, is smaller than the angle a, at which the front edge 198 of the control projection 188 is inclined with respect to the direction of the longitudinal central axis 156 of the sealing element 128, the initial resistance which the user must overcome at the beginning of the transfer of the sealing element 128 from the open position into the closed position is greater than the initial resistance which the user has at the beginning of the transfer of the sealing element 128 must overcome from the closed position to the open position.

After reaching the intermediate position, continued rotation - seen from above - clockwise, the lower edges 202 of the control projections 188 slide along the top 250 of the respectively associated web 244 until finally the front edges 198 of the control projections 188 on the rear edge 254 of the each associated web 244 slide down, whereby the sealing element 128 is lowered vertically downward until the rear edges 196 of the stop projections 190 bear against the front edge 252 of the respectively adjacent web 144 and thus form a stop 304 which prevents the sieve element 124 from moving further and the sealing element 128 coupled therewith prevented in the closing direction.

This is the in again Fig. 43 shown closed position of the sealing element 128 reached.

Furthermore, the second embodiment of the sequence arrangement 100 differs from the first embodiment in that the in the 29 and 30 Coupling element 134 of sieve element 124, which is shown separately, and which is connected in a rotationally fixed manner to base body 132 on the underside of grip section 136 of base body 132 of sieve element 124, unlike that in FIGS 6 and 7 Coupling element 134 shown in the first embodiment, is not essentially cup-shaped, with a closed ceiling wall facing the base body 132, but rather has a coupling receptacle 152 which penetrates the coupling element 134 from top to bottom and which, in the assembled state of the drain arrangement 100, also has a bottom Sealing element 128) and upwards (towards the base body 132 of the sieve element 124) is open.

This alternative embodiment of the coupling element 134 can also be implemented independently of the omission of the support strips 246 on the drain holes 242 of the drain cup 104.

Furthermore, the second embodiment of the drain arrangement 100 differs from the first embodiment in an alternative embodiment of the sealing plug 260, by means of which the end of the overflow connection 110 facing away from the main body 256 of the valve upper part 106 in the delivery state of the drain arrangement 100 or in the operating state of the drain arrangement 100, if no other Overflow or drain to be connected to the drain assembly 100 is lockable.

Like from the 44 to 47 In this embodiment, the sealing plug 260 comprises a substantially hollow cylindrical section 262, the outer diameter of which corresponds essentially to the inner diameter of the overflow connection 110, so that the sealing plug 260 can be inserted sealingly into the end region of the overflow connection 110, preferably with the interposition of a seal ,

The end of the hollow cylindrical section 262 facing away from the valve lower part 112 in the inserted state of the sealing plug 260 is provided with a flange region 264 which projects radially outwards.

When inserting the sealing plug 260 into the overflow connection 110, the flange region 264 serves as a stop, which limits the insertion path of the sealing plug 260 in the longitudinal direction of the overflow connection 110.

One or more, for example two, extensions 306 can be arranged on the outer circumference of the flange region 246, which extensions are, for example, parallel to the longitudinal central axis 272 of the sealing plug 260 and preferably in the direction of the end of the hollow cylindrical section 262 facing the valve lower part 112 when the sealing plug 260 is in the inserted state to extend.

The extensions 306 can serve as injection points if the sealing plug 260 is produced as an injection molded part.

Furthermore, the at least one extension 306 can serve to indicate the angular position of the closure plug 260 when the closure plug 260 rotates about its longitudinal central axis 272, in particular when the closure plug 260 is used to screw the shaft 234 of the guide sleeve 116 into the internal thread of the anchoring element 290 (see Fig. 40 ) is used.

The end of the hollow cylindrical section 262 facing away from the flange region 264 is closed by an end wall 266.

The sealing plug 260 further comprises a tool section 268, which, during assembly or disassembly of the drain arrangement, for connecting the guide sleeve 116 to the in Fig. 39 separately shown lower valve part 112 can be used.

This tool section 268 protrudes from the outside of the end wall 266 along the longitudinal central axis 272 of the sealing plug 260 (see FIGS 46 and 47 ).

The tool section 268 has an outer contour which is complementary to the actuating recess 270 on the head 236 of the guide sleeve 116, so that the tool section 268 is brought into engagement with the actuating recess 270 and then the guide sleeve 116 by rotating the closure plug 260 about its longitudinal central axis 272 can be rotated about the longitudinal central axis 220 of the guide sleeve 116.

In particular, it can be provided that the tool section 269 has a polygonal, for example hexagonal, cross section, taken perpendicular to the longitudinal central axis 272 of the sealing plug 260, and that the actuating recess 270 of the guide sleeve 116 has a polygonal, complementary thereto, taken perpendicular to the longitudinal central axis 220 of the guide sleeve 116. for example hexagonal, cross-section.

How best from the 44 and 45 can be seen, the sealing plug 260 is stiffened by a support structure 274, which comprises a plurality of, for example six, ribs 276 running radially from the inside of the hollow cylindrical section 262 of the sealing plug 260 in the direction of the longitudinal central axis 272 of the sealing plug 260, which ribs at one center Central body 308 arranged in the interior of the closure plug 260, which is preferably essentially cylindrical and preferably projects from the inside of the end wall 266 into the interior of the closure plug 260.

The central body can be provided with an actuating recess 310, preferably arranged in the center.

The actuating recess 310 can have a polygonal, for example hexagonal, cross section and can be brought into engagement with a component that is complementary and also has a polygonal, for example hexagonal, cross section (not shown), by rotating the closure plug 260 about its longitudinal central axis 272 to rotate a longitudinal central axis of the component in question.

The described alternative design of the sealing plug 260 of the second embodiment can also be used regardless of the omission of the support strips 246 and independent of the design of the coupling element 134 without a wall.

Incidentally, that is correct in the 24 to 47 illustrated second embodiment of the sequence arrangement 100 in terms of structure, function and method of manufacture with the in the 1 to 23 illustrated first embodiment, to the above description of which reference is made.
