Overflow or drain assembly and method for mounting an overflow or drain assembly on a basin

Description

[0001] The present invention relates to a combination comprising a basin and an overflow or drain assembly for the basin, in particular a basin of a sink, for example a kitchen sink.

[0002] Such a sink typically features an overflow opening on one of the sink's side walls, through which water can drain from the sink's interior in a controlled manner when the water level in the sink reaches the level of the overflow opening. This prevents the water level from rising to the top of the sink and then causing uncontrolled water flow over the edge.

[0003] Furthermore, basins, especially draining basins, can be provided with a drain opening on their bottom wall through which water standing above the bottom wall can drain away in a controlled manner. Such a drain opening, which is not provided with a closure element to close the opening, is also referred to as a horizontal overflow opening.

[0004] Known overflow assemblies of this type comprise an overflow body with an inlet for fluid passing through the overflow opening. This overflow body is attached directly to a part of the pool wall or to a frame attached to the inside of the pool wall using one or more screws.

[0005] These screws are visible inside the pool or must be covered by an additional cover plate.

[0006] When installing such an overflow assembly, the screws must be handled from the inside of the bowl and the overflow body from the outside, which is time-consuming and difficult, especially if the sink surrounding the bowl is already installed in a countertop. During such a complicated installation, a sealing element intended to seal between the overflow body and the bowl wall can fall off, become crushed, or be damaged, which could require repeated installation or lead to leaks in the overflow assembly.

[0007] When making the screw connection from the inside of the pool, the installer's tool, especially a screwdriver, can slip off the screw and damage, particularly scratch, the inside of the pool. If a screw is overtightened, components of the overflow assembly can be damaged or the pool wall can be bent, especially with thin metal pool walls, resulting in an unsightly appearance.

[0008] EP 3 056 614 A1, DE 86 18 076 U1 and DE 10 2012 215 761 A1 disclose combinations comprising a basin and a drain assembly for the basin, according to the preamble of claim 1.

[0009] The present invention is based on the object of creating a combination of a basin and an overflow or drain assembly which can be mounted in a simple and reliable manner without requiring screwing from the interior of the basin.

[0010] This object is achieved by a combination according to claim 1.

[0011] The invention is based on the concept of connecting the overflow or drain body not by a screw connection from the interior of the pool to the pool wall itself or to a frame placed on the pool wall, but by means of the adapter element to create an interface which is preferably independent of the material of the pool wall and the wall thickness of the pool wall and preferably of the geometry of the overflow or drain opening, to which interface the overflow or drain body can be coupled from a side of the adapter element facing away from the interior of the pool, preferably by means of a coupling or assembly process carried out exclusively in the exterior of the pool.The adapter element can thus compensate for differences in the materials and shapes of the overflow or drain openings on the bowl walls of different sinks, thus forming a standard interface independent of these bowl wall properties, to which a standardized overflow or drain body can be coupled. This allows the overflow or drain body, and preferably also the adapter element, to be used for a variety of different bowls that differ in the design of the overflow or drain opening. This eliminates the need to keep a variety of different overflow or drain assemblies and spare parts in stock, and the manufacturing costs of the overflow or drain assembly can be reduced by producing them in large quantities.

[0012] According to the invention, the adapter element is fixed to the pool wall by means of a material bond, for example by gluing.

[0013] Such bonding can be achieved by means of an adhesive applied to the adapter element and / or to the pool wall or by means of double-sided adhesive tape.

[0014] Furthermore, it can be provided that the adapter element is partially embedded in the material of the pool wall, in particular if the pool is manufactured using a casting process.

[0015] According to the invention, the adapter element can be fixed to an outer side of the pool wall facing away from the interior of the pool.

[0016] In particular, it can be provided that the adapter element is arranged completely on the outside of the pool wall and / or does not extend into the interior of the pool and / or does not extend into the overflow or drain opening.

[0017] In a preferred embodiment of the invention, it is provided that the overflow or drain body can be coupled to the adapter element by positive locking, in particular by locking.

[0018] For example, it can be provided that the overflow or drain body can be coupled to the adapter element by means of a clip connection, a snap connection, a dovetail connection, a locking connection, a Velcro connection and / or a plug connection.

[0019] For the purposes of cleaning, disassembly or repeated assembly of the overflow or drain assembly, it is advantageous if the overflow or drain body can be detachably coupled to the adapter element.

[0020] In particular, it is advantageous if a positive coupling of the overflow or drain body to the adapter element, in particular a locking mechanism, can be unlocked from the outside of the pool wall facing away from the interior of the pool.

[0021] It is advantageous if the overflow or drain body can be coupled to the adapter element without the use of a screwing tool and / or detached from the adapter element without the use of a screwing tool. This eliminates the risk of the basin being damaged, particularly scratched, during installation of the overflow or drain assembly. Furthermore, there is no longer any need for a screwing tool for installing the overflow or drain assembly. With existing overflow assemblies, such a screwing tool is often included in the form of a molded plastic part, which is no longer required after installation and must be disposed of.

[0022] It is particularly advantageous if the overflow or drain body can be connected to and / or detached from the adapter element without any tools, i.e., without the use of tools other than screwing. In this case, only the installer's hands are required for installation of the overflow or drain assembly.

[0023] In a particular embodiment of the invention, it is provided that the overflow or drain body can be brought into engagement with the adapter element and can be moved by a pivoting or rotating movement into a position coupled to the adapter element (coupling position).

[0024] The coupling between the overflow or drain body and the adapter element can be effected, for example, by a coupling device which is designed in particular as a snap mechanism or a bayonet mechanism.

[0025] A coupling device designed as a snap mechanism can in particular comprise one or more locking elements arranged on the overflow or drain body and / or one or more locking elements arranged on the adapter element.

[0026] A coupling device designed as a bayonet mechanism can in particular comprise one, two or more retaining pins arranged on the overflow or drain body and / or one, two or more retaining pins arranged on the adapter element, each of which cooperates with a pin receptacle arranged on the adapter element or on the overflow or drain body.

[0027] Alternatively or additionally, it can be provided that the overflow or drain body can be moved by a guided linear movement into a position coupled to the adapter element (coupling position).

[0028] The adapter element can comprise one or more adapter element-side guide elements which interact with one or more overflow or drain body-side guide elements in order to achieve a guide device for achieving the guided linear movement of the overflow or drain body relative to the adapter element.

[0029] The overflow or drain assembly may comprise a sealing element by means of which an inlet space of the overflow or drain body through which liquid can flow can be sealed in a substantially fluid-tight manner with respect to an outer space of the overflow or drain body.

[0030] Such a sealing element can in particular be formed from an elastomer material.

[0031] Preferably, the sealing element is integrally connected to the overflow or drain body or to the adapter element, in particular by being molded onto one of these elements. This prevents the sealing element from falling off during installation and requiring repositioning or replacement in the event of damage.

[0032] The adapter element preferably has a passage opening for the passage of liquid through the adapter element.

[0033] It is particularly advantageous if the outer contour of the adapter element's through-hole encloses the outer contour of the overflow or drain opening in the pool wall. In this case, the passage of liquid through the overflow or drain opening is not impeded by the adapter element.

[0034] If the overflow or drain assembly is intended for use on different basins, the outer contour of the through-opening of the adapter element is preferably selected so that the adapter element can be arranged on all basins in such a way that the through-opening of the adapter element completely covers the respective overflow or drain opening.

[0035] It can also be provided that the adapter element and the overflow or drain body together define a passage opening for the passage of liquid from the overflow or drain opening into a liquid inlet space of the overflow or drain body.

[0036] In a preferred embodiment of the invention, the adapter element, when the overflow or drain assembly is assembled, does not protrude beyond the inner side of the pool wall, which forms a lateral boundary of the overflow or drain opening, into the interior of the pool. This prevents water or contaminants from accumulating on the adapter element. Furthermore, barrier-free cleaning of the inside of the pool wall is enabled.

[0037] The overflow or drain body can be formed integrally with an overflow or drain pipe, preferably at least partially flexible. This reduces the number of sealing points through which the liquid flowing through the overflow or drain assembly passes. This leads to a reduction in assembly errors and shortens assembly time.

[0038] The overflow pipe is preferably connectable to an overflow connection of an outlet assembly which is connected to an outlet opening in the bottom wall of the basin.

[0039] The adapter element of the overflow or drain assembly is firmly fixed to a wall of the pool.

[0040] The adapter element is glued or welded to the pool wall or at least partially embedded in the pool wall.

[0041] The adapter element can be attached to the pool wall during the pool's manufacture. Attaching the adapter element to the pool wall during the pool's manufacture allows for particularly precise positioning of the adapter element relative to the overflow or drain opening and a particularly good seal between the adapter element and the pool wall.

[0042] However, it is also possible to attach the adapter element to the pool wall after production, for example at the location where the pool is to be used, before the overflow or drain body is coupled to the adapter element.

[0043] At least one material from which the adapter element of the overflow or drain assembly is formed is preferably different from the material of the pool wall.

[0044] Particularly preferably, all materials from which a section of the adapter element is formed are different from the material of the pool wall. The overflow or drain assembly is preferably usable together with a plurality of pools of different types.

[0045] It is therefore particularly suitable as a component of a combination which, in addition to the overflow or drain assembly, comprises at least two basins to which the overflow or drain assembly can be mounted, wherein the basins differ in terms of the shape and / or size of the overflow or drain opening, in terms of the wall thickness of the basin wall in which the overflow or drain opening is arranged, and / or in terms of the material from which the basin is formed.

[0046] The present invention is based on the further object of providing a method for mounting an overflow or drain assembly on a basin, which can be carried out in a simple and reliable manner without the need for screwing from an interior of the basin.

[0047] This object is achieved according to the invention by a method for mounting an overflow or drain assembly on a basin according to claim 12.

[0048] Particular embodiments of the method according to the invention have been explained above in connection with particular embodiments of the overflow or drain assembly.

[0049] The overflow or drain assembly is particularly suitable for use in carrying out the method according to the invention for mounting an overflow or drain assembly on a basin.

[0050] The overflow or drain assembly preferably does not include a screw and can preferably be installed without tools.

[0051] The overflow or drain assembly is preferably mountable on different pools that differ in terms of the geometry of the overflow or drain opening, the wall thickness of the pool wall and / or the material from which the pool wall is formed.

[0052] The pool wall can in particular be made of a metallic material, for example stainless steel, copper or a copper alloy, of a plastic material, of a ceramic material, of a composite material, of concrete or of another material.

[0053] By eliminating the need for screws on the side of the overflow or drain assembly facing the interior of the pool, the visual appearance of the overflow or drain is improved and new possibilities in the design of the overflow or drain are opened up.

[0054] In particular, the overflow or drain opening can be designed to be particularly easy to clean, for example in the form of an elongated slot in the pool wall.

[0055] The assembly can be used as an overflow assembly at an overflow opening in a side basin wall or as a drain assembly at a drain opening in a bottom wall of a basin, in particular a draining basin, a waste basin or a sink trough.

[0056] The overflow opening or the drain opening is preferably not provided with a closure element for closing the opening in question.

[0057] Further features and advantages of the invention are the subject of the following description and the drawings of exemplary embodiments.

[0058] The exemplary embodiments relate to overflow assemblies intended for installation at an overflow opening in a side pool wall. However, these assemblies can also be used as drain assemblies at a drain opening in a bottom wall. All features disclosed below therefore apply equally to overflow assemblies and drain assemblies, with information regarding the horizontal or vertical alignment of elements being interchangeable where appropriate.

and Fig. 43 an enlarged view of area I from Fig. 42 .

[0060] Identical or functionally equivalent elements are designated by the same reference numerals in all figures.

[0061] One in the Fig. 1 bis 6 The basin 100 shown is essentially cuboid-shaped and comprises a bottom wall 102 which, in the assembled state of the basin 100, is essentially horizontally oriented and has an outlet opening (not shown) formed therein, and four lateral basin walls 104 which extend upwards from the bottom wall 102 essentially vertically or inclined relative to the vertical, the inner sides of which facing the interior 106 of the basin 100 form main surfaces 108 of the basin walls 104 which laterally delimit the interior 106.

[0062] At their upper edges, the side basin walls 104 carry a ring-shaped, circumferential basin flange 110, which can be used to attach the basin 100 to a worktop (not shown).

[0063] The basin 100 can be used as a component of a sink, in particular a kitchen sink, for example as an undermount basin, built-in basin, flush-mounted basin or under-flush basin.

[0064] Such a basin 100 can also be embedded in a sink base body which, in addition to the basin 100, comprises, for example, a draining board, a fitting support surface and / or at least one additional basin.

[0065] For example, the rear wall 104 of the pool which is furthest away from the user of the pool 100 in the assembled state is provided with an overflow opening 112 (see Fig. 1 ), which is embedded in the main surface 108 of this pool wall 104.

[0066] As from Fig. 3 As can be seen, the overflow opening 112 is surrounded at its edge by an overflow edge region 114 which runs in a ring around the overflow opening 112 and which is bent at an angle of almost 90° to the outer space 116 of the basin 100 relative to the main surface 108 of the basin wall 104.

[0067] The overflow opening 112 can in principle have any desired cross-section, for example a quadrangular, in particular rectangular, cross-section, which can in particular have rounded corners, a polygonal cross-section, a substantially circular cross-section, an elliptical cross-section or an oval cross-section.

[0068] The basin 100 can, for example, be made of a metallic material, in particular of a steel material, preferably of a stainless steel material, in particular by a deep-drawing process or by bending, wherein the outlet opening and the overflow opening 112 are punched out of the metallic material before or after the deep-drawing process and are brought into the shape described above by one or more stamping or bending processes.

[0069] Alternatively, it can also be provided that the basin 100 is made, in particular cast, from a plastic material, from a ceramic material or from a composite material.

[0070] As can be seen from the Fig. 2 bis 6 As can be seen, an overflow assembly 120 is arranged on the pool wall 104 in the area of ​​the overflow opening 112 on an outer side 118 of the pool wall 104, which overflow assembly 120 has a Fig. 7 bis 11 separately shown overflow body 122 and one in the Fig. 12 bis 16 separately shown adapter element 124.

[0071] The one in the Fig. 7 bis 11 The overflow body 122 shown is preferably made in one piece, for example from a plastic material, in particular from a thermoplastically processable plastic material, particularly preferably from a PP (polypropylene) material or from a POM (polyoxymethylene) material, for example by an injection molding process.

[0072] The overflow body 122 comprises, for example, a substantially rectangular, annularly closed contact area 126 which encloses a water inlet opening 128 of the overflow body 122.

[0073] The contact area 126 has a contact surface 130 facing the adapter element 124 in the assembled state of the overflow assembly 120, which is provided with a groove 132 running annularly around the contact area 126.

[0074] In the assembled state of the overflow assembly 120, an annular closed sealing element 133 is arranged in the groove 132 (see Fig. 3 ), which can basically have any cross-section and can be designed, for example, as an O-ring or as a profile seal with one or more sealing lips.

[0075] The sealing element 133 preferably consists of an elastomeric material that is elastically deformable under contact pressure, in particular of a TPE (thermoplastic elastomer) material.

[0076] The sealing element 133 can be inserted loosely or with a press fit into the groove 132.

[0077] Alternatively, it can also be provided that the sealing element 133 is materially connected to the base body 134 of the overflow body 122, for example, is injection-molded onto the base body 134.

[0078] The contact area 126 of the overflow body 122 is supported by a jacket wall 138 which runs along a rear side 136 of the contact area 126 and which projects from a rear wall 140 of the overflow body 122 which closes the overflow body 122 at the rear towards the contact area 126.

[0079] How best to Fig. 8 As can be seen, a section 142 of the rear wall 140 can have an outer side 144 which, in the assembled state of the overflow assembly 120, is inclined relative to the main surface 108 of the pool wall 104; in particular, it can be provided that this outer side 144 - viewed vertically downwards - is inclined outwards, i.e. away from the pool wall 104.

[0080] Furthermore, the overflow body 122 comprises a drain nozzle 146 which is hollow, wherein the cavity 148 formed in the drain nozzle 146 is in fluid communication with a water inlet chamber 150 of the overflow body 122 which is surrounded by the jacket wall 138, the rear wall 140 and the contact area 126 of the overflow body 122.

[0081] The lower end of the drain connection 146 facing away from the water inlet chamber 150, when the overflow assembly 120 is mounted, is connected to an overflow hose or overflow pipe 152 (see Fig. 2 ).

[0082] The overflow pipe 152 can be connected in a fluid-tight manner to an overflow connection 154 of an outlet assembly 156 at its end facing away from the overflow body 122.

[0083] The outlet assembly 156 is connected to the outlet opening (not shown) in the bottom wall 102 of the basin 100.

[0084] In an alternative embodiment, the overflow pipe 152 can be connected directly to a drain pipe leading to the sewer system.

[0085] The overflow pipe 152 may be formed from the same material as the base body 134 of the overflow body 122.

[0086] The overflow pipe 152 can in particular be formed integrally with the base body 134 of the overflow body 122 or can be connected to the base body 134 in a fluid-tight manner by means of a material bond or press fit.

[0087] This eliminates the need for a sealing point between the overflow pipe 152 and the overflow body 122.

[0088] The overflow pipe 152 may have at least one flexibly bendable section 158, which may be formed, for example, as a bellows.

[0089] In order to be able to couple the overflow body 122 to the adapter element 124 during assembly of the overflow assembly 120, the overflow assembly 120 comprises a coupling device 160, which in turn comprises one or more overflow body-side coupling elements 162 arranged on the overflow body 122 and one or more adapter-side coupling elements 164 arranged on the adapter element 124.

[0090] In the Fig. 1 bis 17 In the first embodiment of the overflow assembly 120 shown, the coupling device 160 is designed as a snap device which comprises, as overflow body-side coupling elements 162, a retaining lug 166, for example hook-shaped, arranged above the water inlet opening 128 of the overflow body 122 and one or more, for example two, locking hooks or snap hooks 168 arranged below the water inlet opening 128.

[0091] The retaining lug 166 projects from an upper bulge 170 of the contact area 126 of the overflow body 122, transversely to the contact surface 130, to the side of the overflow body 122 facing away from the rear wall 140 of the overflow body 122 and, in the assembled state of the overflow assembly 120, to the adapter element 124.

[0092] The snap hooks 168 are each arranged on a tab 172 which extends downwards from the contact area 126.

[0093] Each of the tabs 172 has a smaller thickness than the contact area 126 to allow some flexibility of the tab 172 relative to the contact area 126.

[0094] From a front side 174 of the respectively associated tab 172, the respective snap hook 168 projects towards the side of the overflow body 122 facing away from the rear wall 140 of the overflow body 122 and thus towards the adapter element 124 in the assembled state of the overflow assembly 120.

[0095] The retaining lug 166 and the snap hooks 168 are provided with projections 176 at their respective end regions, wherein the projections 178 of the snap hooks 168 and the projection 176 of the retaining lug 166 preferably face each other.

[0096] The Fig. 12 bis 16 In this embodiment, the adapter element 124 shown is essentially plate-shaped, in the form of a mounting plate or adapter plate 180.

[0097] The outer contour of the adapter element 124 may be substantially rectangular.

[0098] The adapter element 124 has a passage opening 182 for the passage of water from the interior 106 of the pool 100 through the overflow opening 112 in the pool wall 104, through the passage opening 182 of the adapter element 124 and through the water inlet opening 128 of the overflow body 122 into the water inlet space 150 of the overflow body 122.

[0099] The outer contour of the passage opening 182 is selected such that the passage opening 182 essentially completely covers the overflow opening 112 of the basin 100 and, if applicable, also the overflow opening of any other basin 100 on which the overflow assembly 120 is to be arranged.

[0100] The adapter element 124 has a contact surface 184 which, in the assembled state of the overflow assembly 120, faces the outer side 118 of the pool wall 104 and which is preferably substantially planar, and an overflow body contact surface 185 which, in the assembled state of the overflow assembly 120, faces the overflow body 122 and against which the overflow body 122 rests, in particular via the sealing element 133.

[0101] At the contact surface 184, the adapter element 124 can be connected in a materially bonded manner to the outer side 118 of the pool wall 104, for example by means of an adhesive applied to the contact surface 184 of the adapter element 124 and / or to the outer side 118 of the pool wall 104 and / or by means of a double-sided adhesive tape (not shown) arranged between the pool wall 104 and the adapter element 124.

[0102] For example, Fig. 16 As can be seen, the adapter element 124 comprises, as adapter element-side coupling elements 164, a retaining lug receptacle 188 arranged above the passage opening 182 on the outer edge 186 of the adapter element 124 and two snap hook receptacles 190 arranged below the passage opening 182 on the outer edge 186 of the adapter element 124.

[0103] In order to facilitate the coupling of the snap hooks 168 to the snap hook receptacles 190 during assembly of the overflow assembly 120, each snap hook receptacle 190 can be assigned a centering recess 192 which tapers from a lower edge section 194 of the outer contour of the adapter element 124 towards the snap hook receptacle 190.

[0104] A central portion 194 of the adapter element 124, on which the through-opening 182, the retaining lug receptacle 188 and the snap-hook receptacles 190 are arranged, preferably has a thickness (measured perpendicular to the contact surface 184) which is greater than the thickness of an edge portion 198 of the adapter element 124 projecting horizontally and downwardly beyond the central portion 194 (in the assembled state of the overflow assembly 120).

[0105] The adapter element 124 is preferably formed in one piece and manufactured, for example, by an injection molding process.

[0106] The material of the adapter element 124 preferably comprises a plastic material which may be reinforced with fibers, in particular glass fibers, to increase mechanical strength.

[0107] The plastic material of the adapter element can in particular be a thermoplastically processable plastic material, preferably a PP (polypropylene) material or a POM (polyoxymethylene) material.

[0108] The material from which the adapter element 124 is formed may be the same as or different from the material from which the base body 134 of the overflow body 122 is formed.

[0109] The material of the adapter element 124 is preferably different from the material from which the pool wall 104 is formed, to which the adapter element 124 is attached.

[0110] The adapter element 124 may also comprise at least two sections formed from different materials, for example a section made of a metallic material and a section made of a plastic material.

[0111] To mount the above-described overflow assembly 120 on the pool wall 104 in the area of ​​the overflow opening 112, proceed as follows (see the Fig. 4 bis 6 ): First, the adapter element 124 is fixed, with the contact surface 184 facing the outer side 118 of the pool wall 104, in a material-to-material manner to the pool wall 104 such that the passage opening 182 of the adapter element 124 covers the overflow opening 112 in the pool wall 104, preferably substantially completely.

[0112] In particular, it can be provided that the adapter element 124 is fixed to the pool wall 104 by gluing, by means of an adhesive applied to the adapter element 124 and / or the pool wall 104 and / or by means of a double-sided adhesive tape.

[0113] This assembly step is preferably carried out at the factory of the manufacturer of the pool 100, during the manufacture of the pool 100.

[0114] In a later assembly step, which is preferably carried out at the place of use of the basin 100, for example during the assembly of the basin 100 to a worktop, the overflow body 122 is placed on the adapter element 124 already fixed to the basin wall 104 in such a way that the retaining lug 166 of the overflow body 122 engages with its projection 176 in the retaining lug receptacle 188 of the adapter element 124.

[0115] In this case, the overflow body 122 is initially inclined relative to the adapter element 124, i.e. the contact surface 130 on the front side of the overflow body 122 facing the adapter element 124 is inclined relative to the overflow body contact surface 185 of the adapter element 124 facing the overflow body 122, preferably at an acute angle (see Fig. 5 ).

[0116] From this in Fig. 5 In the intermediate assembly position shown, the overflow body 122 is pivoted about a horizontal pivot axis determined by the retaining lug 166 relative to the adapter element 124 into the position shown in Fig. 6 shown coupling position, whereby the snap hooks 168 of the overflow body 122 engage in the snap hook receptacles 190 of the adapter element 124.

[0117] The overflow body 122 is then connected by means of the overflow pipe 152 to the overflow connection 154 of the outlet assembly 156, which has been mounted on the bottom wall 102 of the basin 100.

[0118] This completes the assembly of the overflow assembly 120 on the basin 100.

[0119] Water from the interior 106 of the basin 100, which reaches the height level of the overflow opening 112, flows through the overflow opening 112 in the basin wall 104, through the passage opening 182 in the adapter element 124, through the water inlet opening 128, through the water inlet space 150 and the drain nozzle 146 of the overflow body 122 and through the overflow pipe 152 into the outlet assembly 156 and from there into a drain pipe (not shown) connected to the outlet assembly 156.

[0120] The contact of the sealing element 133 with the overflow body contact surface 185 of the adapter element 124 ensures a fluid-tight seal between the adapter element 124 and the overflow body 122, so that no water can escape between the adapter element 124 and the overflow body 122.

[0121] In order to detach the overflow body 122 from the adapter element, for example for the purpose of cleaning, repair or repeated assembly at a different assembly location or on a different basin 100, the snap hooks 168 of the overflow body 122 are released from the positive locking engagement with the adapter element 124 by bending the tabs 172 away from the adapter element 124 such that the projections 178 of the snap hooks 168 can come out of the respectively associated snap hook receptacle 190.

[0122] After this unlocking, the overflow body 122 is released from the Fig. 6 shown coupling position into the Fig. 5 shown intermediate position, and then the retaining lug 166 of the overflow body 122 is pushed out of the retaining lug receptacle 188 of the adapter element 124, so that the overflow body 122 comes completely out of engagement with the adapter element 124 and can be moved away from the adapter element 124 and from the pool wall 104.

[0123] One in the Fig. 17 bis 33 The second embodiment of an overflow assembly 120 for a basin 100 shown in FIG. 1 differs from that shown in FIGS. Fig. 1 bis 16 illustrated first embodiment in that the overflow body 122 is not movable into the position coupled to the adapter element 124 by a pivoting movement during assembly of the overflow assembly 120, but by a guided linear movement.

[0124] For this purpose, the Fig. 24 bis 28 The overflow body 122 shown has two guide elements 200 as overflow body-side coupling elements 162, which are each arranged laterally next to the water inlet opening 128 of the overflow body 122 and extend in the assembled state of the overflow assembly 120 horizontally away from the contact area 126 of the overflow body 122.

[0125] How best to Fig. 27 As can be seen, each of the guide elements 200 can have a substantially flat front side 202 and a rear side 203 inclined relative to the front side 202 and the contact surface 130 of the overflow body 122.

[0126] The guide elements 200 extend parallel to the contact surface 130 in a guide direction 204 and each have a locking recess 206 on their front side 202 extending transversely to the guide direction 204.

[0127] The Fig. 29 bis 33 In this embodiment, the adapter element 124 shown comprises two guide rails 208 as adapter element-side coupling elements 164, each of which is arranged next to a guide track 210 running in the guide direction 204.

[0128] The guide tracks 204 are preferably arranged laterally next to the passage opening 182 of the adapter element 124 and can be formed as recesses or openings in the adapter element 124.

[0129] The guide rails 208 also extend along the guide direction 204 and are inclined relative to the overflow body contact surface 185 of the adapter element 124 such that they at least partially cover the respectively associated guide track 210, as seen from the side of the adapter element 124 facing the overflow body 122 in the assembled state of the overflow assembly 120.

[0130] An underside of each guide rail 208 facing the guide track 210 forms a, preferably substantially flat, guide surface 212 of the respective guide rail 208.

[0131] At end regions of the guideways 210, for example at the upper end regions in the assembled state of the overflow assembly 120, a locking element 214 is arranged in each case with a locking projection 216 projecting towards the overflow body 122 in the assembled state of the overflow assembly 120.

[0132] Furthermore, each guide track 210 is assigned a stop element 218, which projects from the overflow body contact surface 185 towards the overflow body 122 and limits the displacement path of a guide element 200 of the overflow body 122 engaging in the respective guide track 210 during assembly of the overflow assembly 120.

[0133] The stop elements 218 are preferably arranged on the side of the respective guide track 210 opposite the respective associated guide rail 208.

[0134] The guide rails 208 are preferably arranged on the side of the respective associated guide track 210 facing away from the passage opening 182. The stop elements 218 are preferably arranged on the side of the respective associated guide track 210 facing the passage opening 182.

[0135] To mount the above-described second embodiment of an overflow assembly 120 on the pool wall 104 in the area of ​​the overflow opening 112, proceed as follows (see the Fig. 17 bis 23 ): First, the adapter element 124 is fixed, with the contact surface 184 facing the outer side 118 of the pool wall 104, in a material-to-material manner to the pool wall 104 such that the passage opening 182 of the adapter element 124 covers the overflow opening 112 in the pool wall 104, preferably substantially completely.

[0136] As already mentioned above in connection with the first embodiment, this material connection can be achieved in particular by gluing the adapter element 124 to the pool wall 104.

[0137] This assembly step is preferably carried out at the factory of the manufacturer of the pool 100, during the manufacture of the pool 100.

[0138] As long as the overflow body 122 has not yet been brought into engagement with the adapter element 124, the guideways 210 of the adapter element 124 are empty (except for the locking elements 214 arranged therein), as can be seen from Fig. 20 can be seen.

[0139] In a later assembly step, which is preferably carried out at the place of use of the basin 100, the overflow body 122 is brought to the adapter element 124 (see Fig. 17 ) and placed - with the guide elements 200 first - on the overflow body contact surface 185 of the adapter element 124 in such a way that the guide elements 200 each engage in one of the guide tracks 210 of the adapter element 124 (see Fig. 18 ).

[0140] The guide elements 200 of the overflow body 122 are inserted into the guide tracks 210 in an area of ​​the guide tracks 210 located below the guide rails 208 of the adapter element 124, in which the guide tracks 210 are not overlapped by the guide rails 208.

[0141] From the Fig. 18 In the intermediate assembly position shown, the overflow body 122 is moved along the guide direction 204 relative to the adapter element 124 into the position shown in Fig. 19 shown coupling position, wherein the guide elements 200 reach the area of ​​the guide tracks 210 overlapped by the guide rails 208 of the adapter element 124 and from this point on are guided displaceably on the adapter element 124 along the guide direction 204 by the contact between the rear sides 203 of the guide elements 200 and the guide surfaces 212 of the guide rails 208 facing them (see Fig. 23 ).

[0142] During this sliding movement, each guide element 200 of the overflow body 122 comes into contact with the locking element 214 in the respective associated guide track 210 (see Fig. 21 ), whereupon, upon continuation of the sliding movement along the guide direction 204 upwards, the locking projection of the locking element 214 is deflected by the guide element 200 in the direction of the pool wall 104 and then, due to the spring elasticity of the locking element 214, engages in the locking recess 206 of the guide element 200 when the guide element 200 reaches the respectively associated stop element 218 and thereby comes to rest in the coupling position (see the Fig. 19 and 22 ).

[0143] Subsequently, the overflow body 122 is connected to the overflow connection 154 of the outlet assembly 156 by means of the overflow pipe 152, as described above in connection with the first embodiment.

[0144] This completes the assembly of the overflow assembly 120 on the basin 100.

[0145] In order to release the overflow body 122 from the adapter element 124, the locking elements 214 of the adapter element 124 are released from the positive locking engagement with the guide elements 200 of the overflow body 122.

[0146] This can be done in particular by exerting pressure on the areas of the locking elements 214 not covered by the guide elements 200 of the overflow body 122, so that the locking elements 214 are bent towards the basin wall 104 and their locking projections 216 come out of the locking recesses 206 of the guide elements 200.

[0147] After this unlocking, the overflow body 122 is released from the Fig. 19 illustrated coupling position along the guide direction 204 downwards into the Fig. 18 shown intermediate position, in which the guide elements 200 of the overflow body 122 are no longer in engagement with the guide strips 208 of the adapter element 124, so that the overflow body 122 can be moved away from the adapter element 124 and from the pool wall 104.

[0148] In principle, it can also be provided that the locking elements 214 and the stop elements 218 are arranged at the lower end regions of the guide tracks 210, in which case the overflow body 122 is then suspended above the guide rails 208 during assembly with the guide elements 200 and is moved downwards into the coupling position.

[0149] Furthermore, the Fig. 17 bis 33 illustrated second embodiment of an overflow assembly 120 in terms of structure, function and method of manufacture with the one shown in the Fig. 1 bis 16 illustrated first embodiment, to the above description of which reference is made in this respect.

[0150] One in the Fig. 34 bis 38 The third embodiment of an overflow assembly 120 for a basin 100 shown in FIG. 1 differs from that shown in FIG. Fig. 1 bis 16 illustrated first embodiment in that the coupling device 160 is designed as a bayonet mechanism.

[0151] For this purpose, the overflow body 122 comprises two or more retaining pins 222 as overflow body-side coupling elements 162, each of which is arranged on a retaining block 224, wherein the retaining blocks 224 are each arranged laterally next to the water inlet opening 128 of the overflow body 122 and extend in the assembled state of the overflow assembly 120 horizontally away from the contact area 126 of the overflow body 122 (see the Fig. 34 , 37 and 38 , where in the Fig. 37 and 38 only one of the two retaining pins 222 is visible).

[0152] As best seen from the sectional view of the Fig. 38 As can be seen, each retaining pin 222 extends along a pin axis 226 extending transversely, preferably substantially perpendicularly, to the contact surface 130 of the overflow body 122 towards the adapter element 124.

[0153] Each retaining pin 222 has a smaller diameter portion 228 facing the retaining block 224 and a larger diameter portion 230 facing away from the retaining block 224.

[0154] In this embodiment, the adapter element 124 comprises, as adapter element-side coupling elements 164, a first pin receptacle 232, which is arranged on a first side of the passage opening 182 of the adapter element 124, and a second pin receptacle 234, which is arranged on an opposite side of the passage opening 182 of the adapter element 124.

[0155] The first pin receptacle 232 comprises a recess or an opening 236, which is provided on its edge facing the passage opening 182 with a guide wall 238 which extends from the overflow body contact surface 185 into the area of ​​the opening 236 and partially covers the same.

[0156] As from Fig. 34 As can be seen, the guide wall 238 comprises a U-shaped section 240 in which the two legs 242 of the U are spaced apart by a distance slightly greater than the diameter of the smaller diameter section 228 of one of the retaining pins 222 of the overflow body 122, so that this smaller diameter section 228 can be inserted between the two legs 242 of the U-shaped section 240.

[0157] The longitudinal center axis 244 of the U-shaped section 240 of the guide wall 238 of the first pin receptacle 232 is preferably aligned substantially horizontally in the assembled state of the adapter element 124 (see Fig. 34 ), so that the smaller diameter portion 228 of one of the retaining pins 222 can be inserted into the U-shaped portion 240 in a substantially horizontal direction.

[0158] As from Fig. 38 As can be seen, the front side 246 of the guide wall 238 facing the pool wall 104 in the assembled state of the adapter element 124 has a distance from the outer side 118 of the pool wall 104 which is greater than the axial extent of the section 230 of larger diameter of a holding pin 222 of the overflow body 122 along the pin axis 226, so that the section 230 of larger diameter does not hinder the insertion of the holding pin 222 into the U-shaped section 240 of the guide wall 238, but forms an undercut which prevents the holding pin 222 from moving out of the U-shaped section 240 along the pin axis 226.

[0159] In order to facilitate the insertion of the retaining pin 222 into the U-shaped section 240 of the guide wall 238, the guide wall 238 can have two inlet sections 248 which each adjoin one of the legs 242 of the U-shaped section 240 and which together define an inlet funnel 250 which tapers towards the U-shaped section 240 of the guide wall 238.

[0160] The second pin receptacle 234 of the adapter element 124 also comprises a recess or an opening 252 which is provided at one end region thereof, for example at a lower end region in the assembled state of the adapter element 124, with a guide wall 254 which projects from the overflow body contact surface 185 into the region of the opening 252 and partially covers the opening 252.

[0161] This guide wall 254 comprises a U-shaped section 256, the legs 258 of which are spaced apart by a distance slightly greater than the diameter of the smaller diameter section 238 of one of the retaining pins 222 of the overflow body 122, so that the smaller diameter section 228 of the respective retaining pin 222 can be inserted between the legs 258 of the U-shaped section 256.

[0162] The distance of the front side of the guide wall 254 facing the pool wall 104 in the assembled state of the adapter element 124 from the pool wall 104 is greater than the axial extent of the section 230 of larger diameter of the holding pin 222 along the pin axis 226, so that the section 230 of larger diameter does not hinder the insertion of the holding pin 222 into the U-shaped section 256 of the guide wall 254 of the second pin receptacle 234, but in the inserted state forms an undercut which prevents the holding pin 222 from moving out of the U-shaped section 256 along the pin axis 226. The leg 258a of the U-shaped section 256 facing away from the first pin receptacle 232 is preferably longer than the leg 258b of the U-shaped section 256 of the guide wall 254 of the second pin receptacle 234 facing the first pin receptacle 232.

[0163] As from Fig. 34 As can be seen, the longitudinal central axis 260 of the U-shaped portion 256 of the guide wall 254 of the second pin receptacle 234 is aligned transversely, preferably substantially perpendicularly, to the longitudinal central axis 244 of the U-shaped portion 240 of the guide wall 238 of the first pin receptacle 232.

[0164] To mount the above-described third embodiment of an overflow assembly 120 on the pool wall 104 in the area of ​​the overflow opening 112, proceed as follows (see the Fig. 34 bis 36 ): First, the adapter element 124 is fixed, with the contact surface 184 facing the outer side 118 of the pool wall 104, in a material-to-material manner to the pool wall 104 such that the passage opening 182 of the adapter element 124 covers the overflow opening 112 in the pool wall 104, preferably substantially completely.

[0165] As already described above, this can be done in particular by gluing the adapter element 124 to the pool wall 104.

[0166] This assembly step is preferably carried out at the factory of the manufacturer of the pool 100, during the manufacture of the pool 100.

[0167] In a later assembly step, which is preferably carried out at the place of use of the pool 100, the overflow body 122 is guided from the side of the adapter element 124 on which the first pin receptacle 232 is arranged to the adapter element 124 already fixed to the pool wall 104 (see Fig. 34 ) that one of the retaining pins 222 of the overflow body 122 engages in the opening 236 of the first pin receptacle 232 and reaches the U-shaped section 240 of the guide wall 238 of the first pin receptacle 232, while the other retaining pin 222 is moved past the first pin receptacle 232 and reaches the area of ​​the opening 252 of the second pin receptacle 234 (see Fig. 35 ).

[0168] In this Fig. 35 In the intermediate assembly position shown, the guide wall 238 of the first pin receptacle 232 serves as a stop which prevents further movement of the overflow body 122 relative to the adapter element 124.

[0169] In this intermediate position, the overflow body 122 is tilted relative to the horizontal.

[0170] From this in Fig. 35 In the intermediate assembly position shown, the overflow body 122 is rotated about the pin axis 226 of the retaining pin 222 accommodated in the first pin receptacle 232 relative to the adapter element 124 into the position shown in Fig. 36 shown coupling position, in which the guide wall 254 of the second pin receptacle 234 prevents a continuation of the rotational movement of the holding pin 222 received in the second pin receptacle 234 and thus of the overflow body 122.

[0171] In this coupling position, the positive connection between the larger diameter sections 230 of the retaining pins 222 and the guide walls 238, 254 of the pin receptacles 232, 234 prevents the overflow body 122 from moving away from the adapter element 124 and thus from the basin wall 104, while the positive connection between the smaller diameter sections 228 of the retaining pins 222 and the guide walls 238, 254 of the pin receptacles 232, 234 prevents the overflow body 122 from moving relative to the adapter element 124 in the horizontal direction and from moving upwards or downwards along the overflow body contact surface 185 of the adapter element 124.

[0172] The retaining pins 222 of the overflow body 122 and the pin receptacles 232, 234 of the adapter element 124 thus together form a bayonet mechanism which locks the overflow body 122 in the coupling position to the adapter element 124.

[0173] Finally, the overflow body 122 is connected to the overflow connection 154 of the outlet assembly 156 by means of the overflow pipe 152.

[0174] This completes the assembly of the overflow assembly 120 on the basin 100.

[0175] In order to release the overflow body 122 from the adapter element 124, the overflow body 122 is removed from the Fig. 36 illustrated coupling position about the pin axis 226 of the holding pin 222 accommodated in the first pin receptacle 232 into the Fig. 35 shown intermediate position, in which the retaining pin 222 received in the second pin receptacle 234 is no longer in engagement with the guide wall 254 of the second pin receptacle 234, so that the retaining pin 222 received in the first pin receptacle 232 can be moved out of the U-shaped section 240 of the guide wall 238.

[0176] After removing both retaining pins 222 from the respective associated pin receptacles 232, 234, the overflow body 122 can be moved away from the adapter element 124 and from the pool wall 104.

[0177] Furthermore, the Fig. 34 bis 38 illustrated third embodiment of an overflow assembly 120 in terms of structure, function and method of manufacture with the one shown in the Fig. 1 bis 16 illustrated first embodiment, to the above description of which reference is made in this respect.

[0178] One in the Fig. 39 bis 43 The non-inventive embodiment of an overflow assembly 120 for a basin 100 shown in FIG. 1 differs from the one shown in FIGS. Fig. 1 bis 16 illustrated first embodiment in that the adapter element 124 does not rest on the outer side 118 of the pool wall 104 provided with the overflow opening 112, but on the inner side 262 of this pool wall 104.

[0179] How best to use the Fig. 39 and 42 As can be seen, the adapter element 124 in this embodiment is designed as an adapter frame 264 which comprises a frame-shaped contact flange 266 which is annularly closed and has an outer contour adapted to the shape of the overflow opening 112.

[0180] As is particularly evident from Fig. 42 As can be seen, the adapter element 124, in the assembled state of the overflow assembly 120, rests with a rear side 268 of the contact flange 266 flat against the inner side 262 and thus against the main surface 108 of the pool wall 104.

[0181] At its inner edge, the contact flange 266 of the adapter element 124 merges into a jacket region 270 which is also closed in a ring shape and is bent at an angle of approximately 90° to the outer space 116 of the basin 100 relative to the contact flange 188.

[0182] The jacket region 270, in turn, merges at its end facing away from the interior 106 of the basin 100 into a holding region 272 of the adapter element 124, which is also closed in a ring shape and has a U-shaped cross-section.

[0183] The holding area 272 of the adapter element 124 has a plurality of, for example two, through-openings through which a locking element 274 on the adapter element side extends.

[0184] As best seen from the enlarged view of Fig. 43 As can be seen, each of these locking elements 274 comprises a holding section 276, which is preferably clamped between the holding area 272 and the casing area 270 of the adapter element 124, and a locking rod area 278 projecting beyond the holding area 272 towards the overflow body 122, in which a plurality of locking teeth 280, in the embodiment shown in the drawing six locking teeth 280, follow one another in the axial direction of the locking rod area 278.

[0185] In this embodiment, these adapter element-side locking elements 274 form the adapter element-side coupling elements 164.

[0186] In this embodiment, the adapter frame 264 of the adapter element 124 is preferably formed from a metallic material, in particular from a stainless steel material.

[0187] The adapter element-side locking elements 274 are preferably formed from a plastic material, for example from a PP (polypropylene) material or from a POM (polyoxymethylene) material.

[0188] In this embodiment of the overflow assembly 120, the overflow body 122 comprises, as overflow body-side coupling elements 162, a plurality of, for example two, overflow body-side locking elements 282, which are preferably fixed to two opposite side walls 284 of the water inlet space 150 of the overflow body 122, for example by material connection, form connection or force connection, in particular press fit.

[0189] The overflow body-side locking elements 282 can also be formed integrally with the base body 134 of the overflow body 122.

[0190] As best seen from the enlarged view of Fig. 43 As can be seen, each overflow body-side locking element 282 has a locking tongue 286 which can engage in a space 288 between two adjacent locking teeth 280 of the respectively associated adapter element-side locking element 274.

[0191] In the Fig. 43 In the case shown, the locking tongue 286 engages in the space 288 between the second locking tooth 280b and the third locking tooth 280c of the adapter element-side locking element 274.

[0192] Since, due to the plurality of locking teeth 280, there are a plurality of intermediate spaces 288 and thus a plurality of locking positions in which the locking elements 282 on the overflow body side can be locked with the locking elements 274 on the adapter element side, the overflow body 122 can be coupled to the adapter element 124 in a plurality of coupling positions in this embodiment, wherein these different coupling positions differ from one another with regard to the distance between the rear side 268 of the contact flange 266 of the adapter element 124 on the one hand and the contact surface 130 of the overflow body 122 on the other hand.

[0193] Since the overflow body 122 in this embodiment rests against the outer side 118 of the pool wall 104 via the sealing element 133, which is arranged in the groove 132 provided in the contact surface 130 of the overflow body 122, this embodiment of the overflow assembly 120 can thus be mounted on different pools 100, which differ in terms of the thickness d of the pool wall 104 in which the overflow opening 112 is arranged (see Fig. 42 ).

[0194] This embodiment of the overflow assembly 120 is particularly suitable for basins 100 formed from a plastic material, a ceramic material or a composite material.

[0195] To mount the fourth embodiment of an overflow assembly 120 described above on the pool wall 104 in the area of ​​the overflow opening 112, proceed as follows: The adapter element 124 is inserted into the overflow opening 112 such that the rear side 268 of the contact flange 266 rests against the inner side 262 of the pool wall 104.

[0196] The adapter frame 264 preferably does not extend beyond the outer side 118 of the pool wall 104 into the outer space 116 of the pool 100.

[0197] Subsequently, the overflow body 122 with the overflow body-side locking elements 282 is placed onto the locking rod areas 278 of the adapter element-side locking elements 274 and pressed in the direction of the pool wall 104 until the sealing element 133 and / or the contact surface 130 of the overflow body 122 rests against the outer side 118 of the pool wall 104.

[0198] In this, for example in the Fig. 42 and 43In the coupling position shown, the overflow body 122 is positively coupled to the adapter element 124 by locking.

[0199] The overflow body 122 is then connected to the overflow connection 154 of the outlet assembly 156 by means of the overflow pipe 152.

[0200] This completes the assembly of the overflow assembly 120 on the basin 100.
