Description

[0001] The present invention relates to a sieve element for a drain of a basin, which comprises a base body with at least one sieve opening.

[0002] Such a sieve element is placed in particular on the drain of a basin to retain coarse dirt when liquid drains from the basin through a drain opening of the basin.

[0003] To enable an operator to easily lift the sieve element from the basin drain, particularly for cleaning purposes, it is known to provide such a sieve element with a handle, which is manufactured as a separate part from the base body of the sieve element and attached to the base body. It is also known to form a handle for a sieve element integrally with the base body of the sieve element.

[0004] The familiar handle components, manufactured separately from the main body, are solid, heavy, and complex to produce. Manufacturing a main body with a handle molded as a single piece is complex and limits design freedom in shaping both the main body and the handle.

[0005] US 5 265 281 A discloses a sieve element for a basin drain, comprising a base body with at least one sieve opening and a multi-part handle, wherein the handle includes a handle top part that is movable in a vertical direction relative to the handle bottom part.

[0006] US Patent 4,320,540 A discloses a sieve element for a basin drain, which is manufactured in one piece and includes a one-piece handle.

[0007] US 2007 / 0 000 037 A1 discloses a sieve element for a drain of a basin according to the preamble of claim 1, wherein the upper part of the handle is press-fitted into a recess of the lower part of the handle.

[0008] The present invention is based on the objective of creating a sieve element for a basin drain that is easy to manufacture and offers a great deal of design freedom.

[0009] This problem is solved by a sieve element for a drain of a basin according to claim 1.

[0010] The multi-part design of the handle of the sieve element according to the invention makes it possible to manufacture the upper and lower handle parts separately in simple operations and then to join these parts together. Furthermore, the multi-part design of the handle makes it possible to assemble even more complex handle geometries from simply designed individual parts.

[0011] In a particular embodiment of a sieve element according to the invention, it is provided that the lower part of the handle is formed integrally with the base body.

[0012] Alternatively, it can also be provided that the handle base is a part formed separately from the main body, which extends through a through-opening in the main body.

[0013] The upper part of the handle comprises a deck section which is bordered by a rim section projecting downwards from the outer edge of the deck section, the rim section being curved downwards from the deck section.

[0014] The lower part of the handle has been pressed onto the upper part of the handle in such a way that an upper edge of the lower part of the handle overlaps the edge section of the upper part of the handle.

[0015] In addition, it may be provided that the upper part of the handle is held on a support element which overlaps the lower part of the handle.

[0016] In this case, the sieve element preferably additionally includes a locking element which secures the support element to the handle base, so that the support element, the locking element and the handle base are connected to each other by positive locking.

[0017] In particular, it may be provided that the locking element is latched to the carrier element.

[0018] Preferably, the locking element is designed to engage under the handle base and / or the main body of the sieve element.

[0019] Alternatively or additionally, the upper handle part can be connected to a support element that engages the lower handle part. In this case, an additional securing element can be omitted.

[0020] Furthermore, it may be provided that the upper part of the handle is connected to the support element by means of a rivet connection.

[0021] Alternatively or additionally, it may also be provided that the upper part of the handle is connected to the support element by means of an adhesive bond.

[0022] Alternatively or additionally, it may be provided that the upper part of the handle is connected to the support element by a screw connection.

[0023] Alternatively or additionally, it may also be provided that the upper part of the handle is connected to the support element by a welded connection.

[0024] In a particularly preferred embodiment of the invention, the sieve element is coupled with a sealing element, wherein the sealing element in a closed position seals against an outlet of the basin and in an open position allows a liquid to drain from the basin.

[0025] It is particularly advantageous if the sealing element is held on the sieve element in such a way that it is movable in a vertical direction relative to the sieve element.

[0026] When the sieve element is placed on the outlet of the basin, this vertical direction is inclined relative to the horizontal and preferably oriented essentially vertically.

[0027] The vertically movable mounting of the sealing element on the sieve element makes it possible, in particular, for the sieve element to lie essentially without gaps against the drain of the basin in both the closed and open positions of the sealing element.

[0028] The coupling between the sealing element and the sieve element is particularly easy to implement if the support element of the sieve element includes a cam guide part which has a cam guide by means of which a sealing element is held on the sieve element in such a way that it is movable in the vertical direction relative to the sieve element.

[0029] In one embodiment of the invention, the upper handle part of the sieve element can comprise a sheet metal forming part, which is formed, for example, by a roll forming process from a preform that is cut out of a starting material, in particular by punching or cutting, or a stamped sheet metal part.

[0030] Alternatively, it may also be provided that the upper part of the handle comprises a forged part, a cast part or a part produced by machining from a base material, for example a turned part or a milled part.

[0031] If a joint is formed between the upper part of the handle and the lower part of the sieve element according to the invention, this joint is preferably arranged in the upper half of the multi-part handle of the sieve element, in particular in the upper third of the multi-part handle of the sieve element.

[0032] In particular, it is advantageous if a distance h of the joint from a main surface, especially a top surface, of the base body in which at least one sieve opening is arranged, is greater than half, preferably greater than two-thirds, of the height H of the handle above this main surface.

[0033] This ensures that the joint lies outside the area where coarse dirt accumulates on the top of the sieve element, so that the joint remains largely free of contamination.

[0034] It is particularly advantageous if the sieve element has no joint on its upper side that is located in the lower half of the multi-part handle of the sieve element.

[0037] Identical or functionally equivalent elements are designated with the same reference symbols in all figures.

[0038] One in the Fig. 1, Fig. 2 to Fig. 3. A basin, in particular a sink 102, shown in part and designated as a whole by 100, comprises, in addition to (not shown) side walls, a basin base 104 and a drain flange 106 projecting downwards from the basin base, which surrounds a drain opening 108 of the basin 100, through which liquid, in particular water, can drain from an interior 110 of the basin 100 into a (not shown) drain pipe.

[0039] The drain flange 106 is preferably formed in one piece with the basin floor 104.

[0040] In an outer circumferential wall of the drain flange 106, an annular recess 112, for example in the form of a slot or a groove, is provided.

[0041] The recess 112 can already be incorporated into the drain flange 106 during the manufacture of the basin 100.

[0042] For example, in the case of a basin 100 cast from a flowable starting material in a mold, this can be achieved by appropriately shaping the mold.

[0043] Alternatively or additionally, it may be provided that the recess 112 is produced after the manufacture of the basin 100 by machining, for example by milling.

[0044] For example, basin 100 can be made of a ceramic material, a plastic material without fillers, or a plastic material with fillers.

[0045] As can be seen particularly from the Fig. 1, Fig. 2 to Fig. As can be seen in Figure 3, in the operational state of the basin 100, a drain arrangement 114 is mounted on the drain flange 106 of the basin 100, which includes a drain fitting 116.

[0046] The drain assembly 116 comprises a drain cup 118 with a sealing element 120 and a clamping device 122, by means of which the sealing element 120 can be clamped against the drain flange 106 of the basin 100.

[0047] The sealing element 120 is preferably made of an elastically deformable material, in particular an elastomer material, for example a silicone material or a polyurethane material, and is arranged in a sealing element receptacle 124 on the top of the drain cup 118.

[0048] The sealing element receptacle 124 can, for example, be designed as an annular groove.

[0049] The clamping device 122 for clamping the sealing element 120 against a sealing surface 126 on the underside of the drain flange 106 comprises, for example, a first clamping element 128 and a second clamping element 130.

[0050] The first clamping element 128 is ring-shaped and comprises a lower rigid section 132 and an upper expandable section 134.

[0051] The expandable section 134 comprises a plurality of so-called hooks or locking projections 136 arranged successively in the circumferential direction of the first clamping element 128, wherein each pair of successive locking projections 136 in the circumferential direction is separated from each other by an intervening recess. These recesses enable the expandable section 134 to be expanded.

[0052] On its outer circumferential surface, the first clamping element 128 is provided with a first thread 138, preferably with an external thread.

[0053] The second clamping element 130 is also ring-shaped and comprises a threaded section 142 extending in an axial direction 140 of the drainage arrangement 114 and a clamping section 146 extending inwards from the threaded section 142 in the radial direction 144 perpendicular to the axial direction 140.

[0054] The threaded section 142 is provided on its inner circumferential surface with a second thread 148, preferably an internal thread.

[0055] The second thread 148 of the second clamping element 130 is designed to be complementary to the first thread 138 of the first clamping element 128, so that the second thread 148 of the second clamping element 130 can be screwed to the first thread 138 of the first clamping element 128.

[0056] The assembly of the drain fitting 116 described above on the drain flange 106 of the basin 100 to produce the drain arrangement 114 is carried out as follows: The first clamping element 128, which serves to connect the drain fitting 116 with the drain flange 106, is pushed onto the drain flange 106 of the basin 100 with its expandable section 134 leading, until the locking projections 136 engage in the recess 112 of the drain flange 106.

[0057] In this process, the expandable section 134 initially widens in the radial direction 144 when pushed onto the drain flange 106, by displacing the locking projections 136 outwards from the drain flange 106 so that the locking projections 136 can pass the lower section 150 of the drain flange 106 located below the recess 112.

[0058] Thus, the locking projections 136 of the first clamping element 128 form a locking device 152, by means of which the first clamping element 128 can be locked to the drain flange 106 of the basin 100.

[0059] The recess 112 on the drain flange 106 forms a locking device 154 of the drain flange 106 which cooperates with the locking device 152 of the drain assembly 116, by means of which the drain flange 106 can be locked to the first clamping element 128 of the drain assembly 116.

[0060] In a further assembly step, the second clamping element 130 and the drain cup 118 are brought together with the sealing element 120 by moving the base body 156 of the drain cup 118 through the annular opening 158 surrounded by the clamping section 146 at the lower end of the second clamping element 130 until the drain cup 118 with the sealing element receptacle 124 rests against the clamping section 146 of the second clamping element 130 from above, preferably substantially over a surface.

[0061] The second clamping element 130 is then screwed onto the first thread 138 of the first clamping element 128 using the second thread 148, until the Fig. 2 and Fig. 3 the assembly final state shown is reached, in which the sealing element 120, preferably substantially over a flat area, rests against the sealing surface 126 of the drain flange 106.

[0062] The drain cup 118, the first clamping element 128 and the second clamping element 130 can in principle be made of any material.

[0063] In particular, it may be provided that the drain cup 118, the first clamping element 128 and / or the second clamping element 130 comprise a metallic material and / or a plastic material.

[0064] Preferably, the drain cup 118, the first clamping element 128 and / or the second clamping element 130 are formed essentially entirely from a metallic material or from a plastic material.

[0065] The funnel- or bowl-shaped base body 156 of the drain cup 118 surrounds a cavity 160 inside the drain cup 118, which can be permeated by a liquid passing through the drain cup 118 up to an outlet opening 162 at the lower end of the drain cup 118.

[0066] Furthermore, the drain fitting 116 comprises a subassembly 164 consisting of a sieve element 166 and a sealing element 168 which is slidably held on the sieve element 164.

[0067] The sieve element 166 is in Fig. 9 shown individually and comprises a base body 170, a handle top part 172 and a cam guide part 174.

[0068] The base body 170 of the sieve element 166 is formed in one piece and individually in Fig. 4 shown.

[0069] The base body 170 comprises a substantially cylindrical or slightly conical handle base 176, which surrounds a substantially central through-opening 178 of the base body 170.

[0070] From a lower end of the handle base 176, a substantially flat, preferably substantially horizontally oriented, sieve base section 180 extends outwards in the radial direction 144, in which several sieve openings 182, for example extending in the radial direction 144, are arranged (see also in particular Fig. 1).

[0071] The sieve openings 182 follow one another in the circumferential direction of the sieve element 166 and are preferably spaced substantially equidistant from one another in the circumferential direction.

[0072] The sieve base section 180 of the sieve element 166 is adjoined to the outside by a side wall section 184 of the base body 170, which surrounds the sieve base section 180 in a ring-like manner.

[0073] The upper grip part 172 is in Fig. 5 shown individually and designed, for example, as a sheet metal part.

[0074] The upper part of the handle 172 comprises a substantially circular deck section 186, which is bordered by a rim section 188 projecting downwards from the outer edge of the deck section 186.

[0075] The edge section 188 is bent downwards from the cover section 186 and has, for example, an essentially C-shaped cross-section.

[0076] The upper handle part 172 can, for example, be manufactured by roll forming from a substantially flat preform which has been cut out, in particular stamped out, from a sheet-shaped starting material.

[0077] The upper handle part 172 serves as a cover 190, which is placed on the lower handle part 176 of the base body 156 to close the through-opening 178 of the base body 170, as shown in Fig. 6 is shown.

[0078] For this purpose, the upper handle part 172 is placed on the base body 170 in such a way that the initially cylindrical upper edge 192 of the lower handle part 176 enters the interior 194 of the upper handle part 172, which is bordered by the edge section 188 of the upper handle part 172.

[0079] The lower handle part 176 is then pressed onto the upper handle part 172 by inserting a press punch, preferably with a conical outer contour, through the through-opening 178 of the base body 170 and into the interior 194 of the upper handle part 172. This deforms the upper edge 192 of the lower handle part 176 so that it acquires a shape that widens conically upwards, projects radially outwards from the lower section 196 of the lower handle part 176, and engages behind the edge section 188 of the upper handle part 172, so that the upper handle part 172 is held to the lower handle part 176 by positive locking.

[0080] The scenery guide section 174 is available separately in the Fig. 7 and Fig. 8 shown and has, for example, a substantially cap-shaped form, with a substantially circular upper end wall 198, a substantially hollow cylindrical circumferential wall 200 extending downwards from the edge of the upper end wall 198 and with a stop collar 202 projecting outwards from a lower area of ​​the circumferential wall 200 in the radial direction 144.

[0081] The cam guide part 174 further has on its circumferential wall 200 one or more, in particular two, cam guides 204 for each guide element 206 of the sealing element 168.

[0082] Each of the cam guides 204 comprises a height displacement track 208, along which the guide element 206 is moved in a height direction 210 parallel to the vertical and axial directions 140 of the sequence arrangement 114 relative to the cam guide part 174 by a (in the Fig. 8 and Fig. 9 (shown in broken lines) lower end position can be moved to an upper end position.

[0083] Furthermore, each cam guide 204 includes an insertion channel 212, through which, during the assembly of the assembly 164, the respective guide element 206 of the sealing element 168 can be moved from an edge of the cam guide part 174 to the height displacement track 208 of the cam guide 204.

[0084] Such an introduction channel 212 can in particular comprise an entry section 214 running in the vertical direction 210 and a connecting section 216 connecting the entry section 214 with the vertical displacement track 208, which preferably runs substantially in the circumferential direction of the cam guide part 174.

[0085] If the cam follower 174 has two cam followers 204 as shown in the drawings, these two cam followers 204 are preferably formed and arranged on the cam follower 174 rotated by an angle of rotation of 180° about a central axis 218 of the cam follower 174.

[0086] During the Fig. 7 to Fig. In the embodiment of a cam guide part 174 shown in Figure 8, each cam guide 204 is open towards the outside of the cam guide part 174.

[0087] During the assembly of the sieve element 166, the cam guide part 174, thus formed, is pressed from below into the interior 220 of the multi-part handle 222 of the sieve element 166, which is formed from the upper handle part 172 and the lower handle part 176, until the stop collar 202 rests against the base body 170 of the sieve element 166 from below, so that the cam guide part 174 is held by a press fit on the base body 170 of the sieve element 166 (see Fig. 9).

[0088] To increase the pressing force by which the cam guide part 174 is held in the interior 220 of the handle 222, it can be provided in particular that the circumferential wall of the lower section 196 of the lower part of the handle 176 is inclined at a small angle of, for example, at most approximately 5°, in particular at most approximately 2°, to the axial direction 140, such that the interior 220 of the handle 222 tapers upwards, that is, towards the upper part of the handle 172, at least before the cam guide part 174 is inserted into the interior 220.

[0089] As from Fig. As can be seen in Figure 9, a joint 223 is formed between the upper part of the handle 172 and the lower part of the handle 176 of the multi-part handle 222, wherein this joint 223 is arranged in the upper half of the multi-part handle 222.

[0090] In particular, the distance h of the joint 223 from the top of the sieve base section 180, which forms a main surface 225 of the base body 170 of the sieve element 166, is greater than half the height H of the handle 222 above this main surface 225.

[0091] This ensures that the joint 223 between the upper handle part 172 and the lower handle part 176 is located outside the area where coarse dirt from the flowing liquid accumulates on the top of the sieve element 166. This largely prevents the joint 223 from becoming contaminated.

[0092] The sealing element 168 is in the Fig. 10 and Fig. 11 shown separately and comprises a head part 224, which is, for example, essentially cylindrical, and a substantially disc-shaped sealing part 226 projecting outwards from the head part 224 in the radial direction 144, which is preferably bordered by an outwardly tapered sealing lip 228, as well as a guide part 230 projecting downwards from the head part 224 in the axial direction 140.

[0093] The guide part 230 can be provided on its circumference with one or more guide beads 232 extending essentially along the axial direction 140, which cooperate with complementary guide receptacles on the drain cup 118 in order to prevent rotation of the sealing element 168 relative to the drain cup 118 in the assembled state of the drain arrangement 114.

[0094] Furthermore, the sealing element 168 is provided with one or more guide elements 206 which, in the assembled state of the assembly 164 consisting of the sieve element 166 and the sealing element 168, engage in a respective associated cam guide 204 of the cam guide part 174 of the sieve element 166.

[0095] These guide elements 206 are preferably arranged on the head part 224 of the sealing element 168, in particular near the upper end of the head part 224.

[0096] If two guide elements 206 are present, they are preferably arranged rotated by an angle of 180° around the central axis 234 of the sealing element 168.

[0097] During the assembly of the component 164 consisting of the sieve element 166 and the sealing element 168, the sealing element 168 is moved from below against the pre-assembled sieve element 166 in such a way that the head part 224 of the sealing element 168 immerses in the interior 236 of the cam guide part 174.

[0098] The sealing element 168 is oriented in relation to the sieve element 166 such that the guide elements 206 of the sealing element 168 engage with the inlet section 214 of the insertion channel 212 of the respective associated cam guide 204 on the cam guide part 174.

[0099] The sealing element 168 is moved in the axial direction 140 relative to the sieve element 166 until the guide elements 206 abut the upper end of the respective associated inlet section 214. The sealing element 168 is then rotated relative to the sieve element 166 about the axial direction 140, for example by an angle of approximately 90°, until the guide elements 206 have passed through the connecting section 216 of the inlet channel 212 of the respective associated cam guide 204 and have entered the respective associated vertical displacement track 208.

[0100] In the area where the connecting section 216 merges into the vertical displacement track 208, a narrowing of the connecting section 216 may be provided, which, in the normal operation of the assembly 164, prevents the sealing element 168 from unintentionally detaching from the cam guide part 174 and thus from the sieve element 166.

[0101] As soon as the guide elements 206 of the sealing element 168 are located in the respective assigned height displacement track 208, the sealing element 168 is held on the sieve element 166 in such a way that it is movable in the height direction 210 relative to the sieve element 166.

[0102] In particular, the sealing element 168 can now be removed from its position in Fig. 12 lower end position shown relative to the sieve element 166 in the Fig. The upper end position shown in 13 can be moved.

[0103] In the operation of the drainage arrangement 114, the assembly 164 consisting of the sieve element 166 and the sealing element 168 is arranged at the outlet of the basin 100 such that the sieve element 166, in particular with its side wall section 184, rests on a support surface 238 of the outlet flange 106.

[0104] In this position, the sieve element 166 with the sieve openings 182 serves to retain coarse dirt from a liquid flowing through the drain opening 108 (see the Fig. 2 and Fig. 3).

[0105] The sealing element 168, which is slidably held on the sieve element 166 in the vertical direction 210, lies in its Fig. 2 shown closed position with the sealing part 226 sealing against a support surface 240 of the drain of the basin 100, in particular of the drain cup 118, so that the sealing element 168 in this closed position prevents the flow of liquid from the interior 110 of the basin 100.

[0106] The guide part 230 of the sealing element 168 extends through a guide sleeve 242 of the drain cup 118 in the assembled state of the drain assembly 114, which is guided by (into the Fig. 2 and Fig. 3 (not shown) webs are connected to the base body 156 of the drain cup 118.

[0107] Guide grooves on the inside of the guide sleeve 242 interact with the guide ridges 232 on the guide part 230 of the sealing element 168 in such a way that the sealing element 168 is secured against rotation relative to the drain cup 118.

[0108] From the in Fig. In the closed position shown in Figure 2, the sealing element 168 is engaged by a (not shown) movement device, for example a conventional eccentric movement device, into which Fig. 3 shown open position movable, in which the sealing part 226 of the sealing element 168 is lifted upwards from the support surface 240, so that liquid can drain from the basin 100 through the gap between the sealing part 226 and the drain of the basin 100.

[0109] The movement device for the sealing element 168 is preferably remotely operable by an operator by means of an actuating element arranged next to the basin 100.

[0110] When the sealing element 168 moves from the closed position to the open position, the sealing element 168 is displaced relative to the sieve element 166 along the vertical direction 210, preferably from its lower end position relative to the sieve element 166 to its upper end position relative to the sieve element 166.

[0111] The sieve element 166 remains stationary during this relative displacement of the sealing element 168, so that the sieve element 166 also remains stationary in the position shown in the text. Fig. In the open position shown in section 3, the sealing element 168 still rests without gaps against the support surface 238 of the drain of the basin 100.

[0112] This ensures that even when the sealing element is in the open position, no coarse dirt can pass the sieve element 166 and reach the drain opening 108.

[0113] The base body 170, the handle top part 172, the cam guide part 174 and the sealing element 168 can in principle be made of any material.

[0114] Preferably, the base body 170 and the upper handle part 172 are formed at least partially, preferably substantially completely, from a metallic material.

[0115] The cam follower part 174 is preferably at least partially, and in particular substantially completely, made of a plastic material.

[0116] The sealing element 168 is preferably at least partially, and in particular substantially completely, made of a plastic material, wherein at least the sealing part 226 is preferably made of an elastomeric plastic material.

[0117] One in the Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. The second embodiment of a drainage arrangement 114 shown in Figure 21, comprising an assembly 164 consisting of a sieve element 166 and a sealing element 168, differs from the one shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 first embodiment in that the sealing element 168 is not moved from the closed position to the open position and from the open position to the closed position by means of a movement device by remote actuation, but is instead manually actuated by an operator.

[0118] To enable such manual actuation, the sealing element 168 in this embodiment is additionally provided with one or more, for example four, spacer elements 244, which are preferably arranged on the underside of the sealing part 226 (see in particular the Fig. 18 and Fig. 19).

[0119] Each spacer element 244 can have the form of a web 246, which is preferably oriented transversely, in particular substantially perpendicularly, to the radial direction 144 of the sealing element 168.

[0120] If several spacer elements 244 are present, they are preferably arranged successively along the circumferential direction of the sealing element 168 and, preferably, are spaced apart from each other at substantially equidistant intervals.

[0121] How best to get from the Fig. 16 and Fig. As can be seen in Figure 18, each spacer element 244 can be provided with a recess 248 on its underside.

[0122] How best to get from the Fig. 15 and Fig. As can be seen in Figure 17, the guide sleeve 242 of the drain cup 118 is connected to the base body 170 of the drain cup 118 via several, for example four, webs 250.

[0123] In this embodiment, these webs 250 serve as support elements 252, against which the spacer elements 244 of the sealing element 168 can be supported in the open position of the sealing element 168, in order to position the sealing part 226 of the sealing element 168 at a predetermined distance D in the vertical direction 210 (see Fig. 16) from the support elements 252 and thus be able to lift off from the drain cup 118.

[0124] As from the Fig. 15 and Fig. As can be seen in Figure 17, the guide sleeve 242 of the drain cup 118 has one or more stop channels 454 on its inside, each of which accommodates a guide bead 232 serving as a sealing element-side stop element 256 on the guide part 230 of the sealing element 168.

[0125] Each stop channel 254 forms a (in the in Fig. 15 shown first direction of rotation 258) front end of the stop channel 254 a front outlet-side stop element 260 and (seen in the first direction of rotation 258) rear end of the stop channel 254 a rear outlet-side stop element 262.

[0126] As from Fig. As can be seen in Figure 15, in the closed position of the sealing element 168, each sealing-element-side stop element 256 rests against the respective associated rear drain-side stop element 262, while in the Fig. In the open position of the sealing element 168 shown in 17, each sealing element-side stop element 256 rests against the respective assigned front drain-side stop element 260.

[0127] As from the Fig. 20 and Fig. As can be seen in Figure 21, the sealing element 168 is also held on the sieve element 166 in this embodiment in such a way that it is separated from the sieve element 166 in the vertical direction 210. Fig. 20 shown lower end position into the Fig. The upper end position shown in 21 is movable.

[0128] The assembly 164, consisting of the sieve element 166 and the sealing element 168, is inserted into the drain arrangement 114 such that in the Fig. 14 and Fig. In the closed position of the sealing element 168 shown in Figure 15, the spacer elements 244 of the sealing element 168 are each arranged between two support elements 252 of the drain cup 118 and thus do not engage with the support elements 252 in the closed position, so that the sealing part 226 of the sealing element 168 rests in a sealing manner against the bearing surface 240 of the drain cup 118 in the closed position.

[0129] To manually move the sealing element 168 from this closed position into the Fig. 16 and Fig. To convert the disclosure shown in section 17, the following procedure is used: The operator grasps the handle 222 of the sieve element 166 and moves the sieve element 166 upwards in the vertical direction 210.

[0130] The sealing element 168, which in the closed position is in its lower end position relative to the sieve element 166, follows this vertical movement of the sieve element 166.

[0131] The sieve element 166 is then placed by the operator in the Fig. 15 first direction of rotation 258 is rotated about the central axis 218.

[0132] Since the sealing element 168 is rotationally fixed to the sieve element 166 via the guide elements 206 located in the height displacement track 208 of the respective associated cam guide 204, the sealing element 168 follows this rotational movement until the stop elements 256 on the sealing element side abut the respective associated front outlet-side stop elements 260 (see Fig. 17). The rotationally fixed connection between the sealing element 168 and the sieve element 166 also stops the rotational movement of the sieve element 166 in this angular position.

[0133] The operator then releases the handle 222 of the sieve element 166 or lowers it in the vertical direction 210.

[0134] The sealing element 168 follows this lowering movement until the spacer elements 244, which are now located vertically above the support elements 252 of the drain cup 118 and cross them (see Fig. 17), resting on the support elements 252.

[0135] Preferably, the upper edges of the support elements 252 engage in the recess 248 of the respective associated spacer element 244.

[0136] When the spacer elements 244 rest on the support elements 252, the sealing part 226 of the sealing element 168 is spaced away from the bearing surface 240 of the drain cup 118 (see Fig. 16), so that the sealing element 168 is in its open position, in which it allows liquid to flow out of the interior 110 of the basin 100.

[0137] After the sealing element 168 rests on the support elements 252 of the drain cup 118, the sieve element 166 continues to move downwards in the vertical direction 210 until its side wall section 184 rests on the bearing surface 238 of the drain flange 106, so that the entire drain opening 108 is completely covered by the sieve element 166.

[0138] This relative movement between the sieve element 166 and the sealing element 168 is made possible by the fact that the guide elements 206 of the sealing element 168 move upwards in the height displacement path 208 of the respective associated cam guide 204 relative to the cam guide part 174 of the sieve element 166.

[0139] Preferably, the sealing element 168 is located slightly below its upper end position relative to the sieve element 166 when the sieve element 166 rests on the support surface 238 of the drain flange 106.

[0140] To remove the sealing element 168 from the into the Fig. 16 and Fig. 17 disclosures shown in the Fig. 14 and Fig. To convert to the closed position shown in section 15, the following procedure is used: The operator grasps the handle 222 of the sieve element 166 and turns it in the Fig. 17 the second direction of rotation 264 shown, which is opposite to the first direction of rotation 158, about the central axis 218.

[0141] The sealing element 168, which is non-rotatably connected to the sieve element 166, follows this rotational movement, whereby the sealing element 168 is simultaneously raised slightly, as the edges 266 of the recesses 248, which run at an angle to the horizontal, on the underside of the spacer elements 244 run against the stationary support elements 252 of the drain cup 118, until the support elements 252 come out of engagement with the spacer elements 244.

[0142] Since the sealing element 168 is arranged in its open position below its upper end position relative to the sieve element 166, this lifting of the sealing element 168 relative to the sieve element 166 can take place without the sieve element 166 being lifted from the support surface 238 of the drain flange 106.

[0143] As soon as the spacer elements 244 are out of engagement with the support elements 252, the sealing element 168 falls downwards in the vertical direction 210 due to gravity relative to the sieve element 166 until the sealing part 226 of the sealing element 168 again seals against the support surface 240 of the drain cup 118.

[0144] The rotational movement of the sieve element 166 and the sealing element 168 in the second direction of rotation 264 is stopped when the sealing element-side stop elements 256 strike the respective associated rear drain-side stop elements 262.

[0145] Then it's again the one in the Fig. 14 and Fig. The closing position of the sealing element 168 shown in section 15 is reached.

[0146] Moreover, the one in the Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. 21 shows a second embodiment of a drainage arrangement 114 with an assembly 164 consisting of a sieve element 166 and a sealing element 168, with regard to structure, function and manufacturing method, compared to the embodiment shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 first embodiment shown, to the foregoing description of which reference is made in this respect.

[0147] One in the Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27, Fig. 28 to Fig. The third embodiment of a drainage arrangement 108 shown in Figure 29, comprising an assembly 164 consisting of a sieve element 166 and a sealing element 168, differs from the one shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 first embodiment shown by the construction and manufacturing method of the sieve element 166.

[0148] The in Fig. 24 depicted handle top 172 and the one in Fig. The basic bodies 170 of the sieve element 166 shown in Figure 27 are essentially the same in this embodiment as in the first embodiment.

[0149] In this embodiment, however, the upper handle part 172 is not pressed directly onto the lower handle part 176, but rather onto the part in Fig. 25 shown, the cam guide part 174 is defined, which serves as a support element 274 for the handle upper part 172.

[0150] For this purpose, the cam guide part 174 has, instead of a stop collar 202 in the area of ​​the lower end of the cam guide part 174, an upper end wall 198 projecting beyond the circumferential wall 200 in the radial direction 144, as well as one or more locking elements 268, for example in the form of locking lugs, at the lower end of the cam guide part 174. The locking elements 268 are preferably arranged successively and spaced apart from one another in the circumferential direction of the cam guide part 174.

[0151] The upper handle part 172 is attached, for example by crimping, to the upper end wall 198 of the cam guide part 174 (see Fig. 26).

[0152] The pre-assembled unit formed from the cam guide part 174 and the upper handle part 172 is then inserted from above into the through-opening 178 of the base body 170 of the sieve element 166 until the upper end wall 198 abuts the upper edge of the lower handle part 176.

[0153] The inner contour of the lower handle part 176 is designed to widen conically towards the top in order to keep the joint 223 between the upper handle part 172 and the lower handle part 176 as small as possible and / or to ensure that the lower handle part 176 overlaps the upper handle part 172.

[0154] Subsequently, the pre-assembled unit consisting of the cam guide part 174 and the handle upper part 172, which is inserted into the base body 170 of the sieve element 166, is secured by means of a Fig. 28 shown, the securing element 270, in particular a retaining ring, is secured against unintentional detachment from the base body 170.

[0155] The locking element 270 is provided on its inside with a locking element 272, for example an annular locking projection, which, after the locking element 270 is pushed onto the circumferential wall 200 of the cam guide part 174 from below, locks into the locking elements 268 of the cam guide part 174, so that the cam guide part 174 and the upper handle part 172 are connected to the base body 170 by positive locking.

[0156] The locking element 270 rests with its upper side, preferably substantially flat, against the underside of the base body 170.

[0157] Furthermore, this third embodiment of a drainage arrangement 114 corresponds to an assembly 164 consisting of a sieve element 166 and a sealing element 168, which in Fig. 22 in the closed position of the sealing element 168 and in Fig. 23 in the open position of the sealing element 168, with regard to structure, function and manufacturing method with the one in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 first embodiment shown, to the foregoing description of which reference is made in this respect.

[0158] One in the Fig. 30 and Fig. Figure 31 shows a fourth embodiment of a drainage arrangement 114 with an assembly 164 consisting of a sieve element 166 and a sealing element 168, which differs from the one shown in the Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. 21 second embodiment with regard to the structure and manufacturing method of the sieve element 166.

[0159] The sieve element 166 of the fourth embodiment is constructed and manufactured as described above in connection with the one described in the Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27, Fig. 28 to Fig. The third embodiment shown in 29 has been described.

[0160] Moreover, the fourth embodiment, which is in Fig. 30 in a closed position of the sealing element 168 and in Fig. 31 in an open position of the sealing element 168, with regard to its construction, function and method of manufacture, in particular with regard to the manual actuation of the sealing element 168, with which in the Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. 21 corresponds to the second embodiment shown, to the foregoing description of which reference is made in this respect.

[0161] One in the Fig. 32, Fig. 33, Fig. 34 to Fig. The fifth embodiment of a drainage arrangement 114 shown in Figure 35, comprising an assembly 164 consisting of a sieve element 166 and a sealing element 168, differs from those shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. The first and second embodiments shown in Figure 21 differ only with regard to the structure and manufacturing method of the sieve element 166, which is why only the sieve element 166 and its components are shown for this embodiment.

[0162] In this fifth embodiment, the cam guide part 174 forms a support element 274 which, in the assembled state of the sieve element 166, engages the lower handle part 176.

[0163] The in Fig. In this embodiment, the upper handle part 172 shown in Figure 32 is provided on the underside of the deck section 186 with a rivet 276, for example in the form of a substantially hollow cylindrical projection.

[0164] The rivet 276 is preferably arranged substantially in the middle of the upper part of the handle 172.

[0165] The rivet 276 can be fixed to the deck section 186 after the shaping of the deck section 186 and the edge section 188 of the handle top 172, for example by welding.

[0166] In this embodiment, the cam guide part 174 has a passage opening 278 in the upper end wall 198, preferably in a substantially central location, through which the rivet 276 passes when the cam guide part 174 is inserted from below into the passage opening 178 of the lower handle part 176 of the base body 170 of the sieve element 166, until the stop collar 202 of the cam guide part 174 abuts the base body 170 of the sieve element 166, and the upper handle part 172 is placed from above onto the lower handle part 176 and the cam guide part 174.

[0167] The cam guide part 174 is preferably received in a press fit in the handle lower part 176 of the base body 170.

[0168] Subsequently, the rivet 276 of the upper handle part 172 is deformed by means of a press punch which is inserted into the interior 236 of the cam guide part 174, such that after deformation a lower edge of the rivet 276 engages the edge area of ​​the passage opening 278 of the cam guide part 174, so that the cam guide part 174 is connected to the upper handle part 172 by positive locking.

[0169] Moreover, the one in the Fig. 32, Fig. 33, Fig. 34 to Fig. 35 fifth embodiment with regard to structure, function and method of manufacture with the one shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 first embodiment (for remote actuation of the sealing element 168) or with the one described in the Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. 21 shown second embodiment (for manual actuation of the sealing element 168), to the above description of which reference is made in this respect.

[0170] One in the Fig. 36, Fig. 37, Fig. 38 to Fig. Figure 39 shows a sixth embodiment of a drainage arrangement 114 with an assembly 164 consisting of a sieve element 166 and a sealing element 168, which differs from those shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20 to Fig. The first and second embodiments shown in Figure 21 differ only in terms of the structure and manufacturing method of the sieve element 166, which is why only the sieve element 166 and its components are shown in this embodiment.

[0171] In this embodiment, the cam guide part 174 serves as a support element 274, which engages the lower handle part 176.

[0172] The in Fig. 36 illustrated handle top 172, which is in Fig. 37 basic bodies shown 170 and the one in Fig. The cam track guide part 174 shown in section 38 is essentially designed the same as in the first embodiment.

[0173] However, in this embodiment, the upper handle part 172 is not directly connected to the lower handle part 176 by compression, but rather the upper handle part 172 is glued to the cam guide part 174.

[0174] In this embodiment, the lower handle part 167 is preferably designed to taper slightly conically towards the top. Preferably, the circumferential surface of the lower handle part 176 is inclined at a small angle of, for example, at most approximately 5°, and in particular at most approximately 2°, relative to the central axis 218.

[0175] In the manufacture of the sieve element 166, the upper handle part 172 is placed on the lower handle part 176, so that the underside of the upper handle part 172 abuts the upper edge of the lower handle part 176.

[0176] Then an adhesive is applied to the underside of the upper handle part 172.

[0177] The cam guide part 174 is then pressed from below into the through opening 178 of the handle base 176 until the stop collar 202 of the cam guide part 174 rests against the underside of the base body 170 and the cam guide part 174 comes into contact with the adhesive.

[0178] After the adhesive has hardened, the cam guide part 174 is held in place both by bonding to the upper handle part 172 and by the press fit in the lower handle part 176.
