DRAINAGE DEVICE

Description

[0001] The present invention relates to a drainage device for at least partial installation in the floor of a room according to the preamble of claim 1 and to a drainage device for draining a room with such a drainage device.

[0002] A drain device of the aforementioned type is known from EP 2 617 908 A1. The drain device described therein comprises a device for adjusting the height of a drain housing. This device comprises a three-part telescopic base, the parts of which can be pushed into one another and moved relative to one another. In one of the embodiments described in EP 2 617 908 A1, at least one of the parts can have a non-circular section with parallel ribs. The parts of the base can be secured relative to one another by rotating the parts relative to one another.

[0003] Another drainage device is known from DE 20 2011 001 135 U1. The drainage device described therein comprises a drain housing supported by base parts with height-adjustable feet via a thread.

[0004] Another drainage device is known from US Pat. No. 5,971,662 A. The drainage device described therein comprises a drain housing held by rods extending upwards from the floor. The rods are held in receptacles in which they are secured by friction. Upon application of a force exceeding the frictional force, the receptacles can be moved relative to the rods.

[0005] Another drainage device is known from DE 20 2010 008 258 U1. The drainage device described therein comprises a drain housing supported by feet, each of which is height-adjustable via a thread.

[0006] Another drainage device is known from US Pat. No. 5,154,024 A. The drainage device described therein comprises a drain housing held by rods extending upwards from the floor. The rods are held in receptacles in which they can be secured by screws.

[0007] Another drainage device is known from DE 10 2006 051 130 B4. The drainage device described therein comprises a drain body with a drain outlet that can be connected to a drain line. The drain device is mounted on the subfloor before the screed is laid. For this purpose, the drain body has a collar held by four height-adjustable feet. The feet have threaded rods so that by turning the threaded rods in corresponding internal threads, the height of the collar and thus the drain body above the subfloor can be adjusted. A disadvantage of this is that adjusting to larger height differences by turning the individual threaded rods is comparatively time-consuming.

[0008] The problem underlying the present invention is the creation of a drainage device and a drainage device of the type mentioned above, which enable a faster adjustment of the height of the drain housing above the unfinished floor.

[0009] This is achieved by a drainage device of the type mentioned at the outset with the characterising features of claim 1 and by a drainage device with the features of claim 6.

[0010] The subclaims relate to preferred embodiments of the invention.

[0011] According to claim 1, the drainage device comprises a plurality of plugs, each of which can be applied to the upper sides of the rods and which have a cover plate and three or four webs projecting downward from the cover plate. The webs project precisely into the spaces between the projections of the contour of the respective rod. By rotating the plug, the rod connected to the plug can be rotated in the circumferential direction. The cross-section of such a contour can continue unchanged, in particular, in the longitudinal direction of the rod. This allows one contour to be moved along the other contour.

[0012] The clamping devices allow the drain body to be set at a desired height relatively quickly.

[0013] For example, four supports can be provided essentially at the four corners of the drain body.

[0014] In the first position, the drain body can be adjusted to the desired height during installation without having to twist threaded rods or the like. Once the desired height is reached, the two interacting contours are moved into the second relative position, thus securing the drain body relative to the at least one support.

[0015] It is possible that the rod extends vertically upwards from the subfloor when the drainage device is installed.

[0016] Each of the supports can be provided with a mounting base that can be attached to the subfloor, with one of the rods extending upwards from each of the mounting bases. The mounting bases and the rods can be easily mounted on the subfloor.

[0017] Alternatively, the supports can be provided with a base plate that can be attached to the subfloor, with several rods extending upwards from the base plate when installed. The base plate determines the positions of the rods, thus simplifying the connection to the drain body.

[0018] The drain device is intended to comprise a plurality of receptacles that are connected to the drain housing or arranged on the drain housing. For example, the receptacle can be arranged on a collar surrounding the drain housing. It is certainly possible to arrange the receptacle on other parts or sections of the drain housing.

[0019] It is designed so that each of the rods can engage in one of the receptacles. This allows the drain body to be moved vertically relative to the supports when the rods are inserted into the receptacles.

[0020] It is provided that one of the contours that are part of the clamping means is arranged or formed on the inner sides of the receptacles. The contour on the inner side of the receptacle has radially inwardly projecting projections or adjacent sections in the circumferential direction that alternately project radially inward to a greater or lesser extent. The cross-section of such a contour can continue unchanged, particularly in the longitudinal direction of the receptacle. This allows one contour to be moved along the other contour.

[0021] It can be provided that the transition from the first relative position of the two interacting contours to the second relative position of the two interacting contours is achieved by rotating the rod in the receptacle in the circumferential direction, in particular by an angle between 10° and 180°, preferably by an angle between 20° and 120°, for example by an angle of 45° or 90°. Fixing the drain housing at a desired height can thus be achieved very easily by briefly twisting the individual rods. This significantly simplifies the positioning of the drain housing.

[0022] According to claim 6, it is provided that the drainage device comprises a drainage device according to the invention.

[0023] Further features and advantages of the present invention will become clear from the following description of preferred embodiments with reference to the accompanying drawings. Fig. 1 is an exploded view of an embodiment of a drainage device according to the invention; Fig. 2 is a detailed view according to the arrow II in Fig. 1 ; Fig. 3 a perspective view of the embodiment according to Fig. 1 ; Fig. 4 a side view of the embodiment according to Fig. 1 ; Fig. 5 a sectional view according to the arrows V - V in Fig. 4 ; Fig. 6 a plan view of the embodiment according to Fig. 1 ; Fig. 7 is a perspective view of a drainage device which is not part of the invention; Fig. 8 is a plan view of the drainage device according to Fig. 7 ; Fig. 9 a sectional view according to the arrows IX - IX in Fig. 8 ; Fig. 10 a detailed view according to the arrow X in Fig. 8 ; Fig. 11 a side view of a detail of a support foot with clamping means, which is not part of the invention; Fig. 12 a sectional view according to the arrows XII - XII in Fig. 11 ; Fig. 13 a side view of a detail of another support foot with clamping means, which is not part of the invention; Fig. 14 a plan view of the support foot according to Fig. 13 .

[0024] In the figures, identical or functionally identical parts are provided with the same reference symbols.

[0025] The Fig. 1 bis Fig. 6 The illustrated embodiment of a drainage device according to the invention comprises a drain housing 1 with an upper inlet opening 2 and two drain openings 3, 4, which are formed by drain nozzles integrated into the drain housing 1 (see Fig. 1 and Fig. 5 ). It is possible that during installation, according to local requirements, one of the drain openings 3, 4 is provided with a blind plug and the other of the drain openings 3, 4 is connected to a drain line 5.

[0026] The drain body 1 is mounted on the subfloor before the screed is applied and connected to a drainpipe. The screed is then applied to the subfloor so that the drain body 1 is at least partially surrounded by the screed. The floor, including the already installed drain components, is then sealed, in particular with a composite seal.

[0027] The drain body 1 is surrounded by a collar 6 having a plurality of openings 7. The openings 7 can be at least partially penetrated by the screed during application of the screed.

[0028] The drainage device may further comprise water collection means (not shown), which are particularly designed as a drainage channel. The drainage channel can be arranged above the drain body 1 after the screed and composite waterproofing have been applied, so that wastewater entering the drainage channel can flow from a drain opening of the drainage channel into the inlet opening 2 of the drain body 1. It is certainly possible for the water collection means not to be designed as a channel, but rather, for example, to have a rotationally symmetrical shape.

[0029] The drainage device further comprises a plurality, in particular four, supports 8. The supports 8 each comprise a rod 9, which is in particular vertical in the assembled state, and a fastening foot 10, which can be fastened to the subfloor, in particular by screwing. Fig. 1 The corresponding dowels 11 and screws 12 are shown.

[0030] The rod 9 extends through a receiving sleeve 13 of the mounting base 10 such that the mounting base 10 can be moved along the rod 9 prior to assembly. The rod 9 has a lower base plate 14 beyond which the mounting base 10 cannot be pushed downward.

[0031] The drainage device further comprises a plurality of, in particular four, decoupling units 15, each of which can be arranged beneath the base plate 14 to ensure sound decoupling. It is entirely possible to dispense with the decoupling units 15.

[0032] The drain device further comprises a plurality, in particular four, receptacles 16 for the rods 9. The receptacles 16 are sleeve-like, allowing the rods 9 to extend through them. The receptacles 16 are formed on the collar 6 surrounding the drain housing 1.

[0033] It is certainly possible to arrange the receptacles 16 on other parts or sections of the drain body 1.

[0034] The outer side of one, in particular each of the rods 9 has a cross-section deviating from a circular shape or a contour 17, which continues unchanged in the axial direction of the rods 9. In the Fig. 1 bis Fig. 6 In the first embodiment shown, the contour 17 consists of three projections 18 projecting radially outwards at equal angular intervals of approximately 120° (see in particular Fig. 2 ).

[0035] The inner side of one, in particular each of the receptacles 16 also has a cross-section deviating from a circular shape or a contour 19 which continues unchanged in the axial direction of the rods 9. Fig. 2 shows that the contour 19 has adjacent sections 20, 21 in the circumferential direction of the receptacle 16, which alternately project more or less radially inwards.

[0036] In this way, a rod 9 located in the receptacle 16 can be moved unhindered in the vertical direction through the receptacle 16 in a first rotational position of the rod 9. In a second position rotated relative to the first rotational position, however, the rod 9 is clamped in the receptacle 16. The contours 17, 19 thus act as clamping means for securing the drain body 1 at different heights relative to the support 8 or at different heights above the subfloor. The transition from the first to the second position can be achieved, for example, by rotating the rod 9 in the circumferential direction by approximately 90°.

[0037] It is certainly possible to provide contours 17, 19 of the rods 9 or the receptacles 16, in which the transition from the first to the second position takes place by a rotation of the rod 9 in the circumferential direction by less or more than 90°, for example by a rotation of 30° or 45° or 60° or another suitable angle.

[0038] In this way, the height of the drain body 1 above the subfloor can be easily specified before the screed is poured. The rods 9 are secured to the subfloor using the mounting feet 10 and, if necessary, the decoupling units 15. Subsequently, the holders 16 of the drain body 1 are placed on the rods 9. The drain body 1 can now be moved up and down vertically until it is at the correct height, for example, where the selected drain outlet is level with the drain line 5.

[0039] This height of the drain body 1 above the subfloor is fixed by rotating the rods by, for example, 90°. Any sections of the rods 9 that protrude upwards above the mounts 16 are cut off.

[0040] The Fig. 1 bis Fig. 6 The drainage device shown further comprises a plurality, preferably four, plugs 22, which can each be applied to the upper sides of the rods 9. For this purpose, the plugs 22 have a cover plate 23 and three webs 24 projecting downwards from the cover plate 23, which can each project exactly into the spaces between the projections 18 of the contour 17 of the respective rod 9 (see Fig. 2 ).

[0041] As a result, the rod 9 connected to the plug 22 can be rotated circumferentially by rotating the plug 22. To facilitate the rotation of the plug 22, the plug has a slot 25 for a screwdriver on the top side of its cover plate 23 as an engagement means.

[0042] After the drain body 1 has been fixed at a desired height, the plugs 22 can be used to close the upwardly open receptacles 16. If the drain body 1 is fixed at a height at which the rods 9 protrude upwardly from the receptacles 16, these projecting sections of the rods 9 are cut off so that the plugs 22 can be inserted into the receptacles 16 from above.

[0043] The drainage device according to Fig. 7 bis Fig. 10 Instead of the four separate mounting feet, it has a base plate 26, on the upper side of which four receiving sleeves 27 are provided for the rods 9. The base plate 26 offers the advantage that the distances between the receiving sleeves 27 are predetermined at the factory, and thus the rods 9 projecting upward from the receiving sleeves 27 are positioned to match the receptacles 16 on the drain body 1.

[0044] The receiving sleeves 27 can be designed like the receiving sleeves 13 of the fastening feet, so that the rod 9 is rotatably received in the corresponding receiving sleeve 27 (see for example Fig. 9 ).

[0045] However, it is also possible that the lower end of the rod 9 has an external thread 35 (see Fig. 11 ) and the mounting sleeve is provided with a matching internal thread. This allows for fine adjustment of the height by rotating rod 9.

[0046] In Fig. 10 , Fig. 12 and Fig. 14 further possible contours 17 of the rods 9 forming the clamping means as well as further possible contours 19 of the receptacles 16 are shown.

[0047] The Fig. 10 The contour 17 shown has adjacent sections 28, 29 in the circumferential direction, which alternately project radially outward to a greater or lesser extent. Accordingly, the cross-section, or contour 19, of the receptacle 16, which deviates from a circular shape, has adjacent sections 20, 21 in the circumferential direction, which alternately project radially inward to a greater or lesser extent.

[0048] At the bars 9 according to Fig. 12 and Fig. 14 The contour 17 of the rods 9 has four radially outwardly extending projections 30. The projections on the contour 17 of the rod 9 are according to Fig. 14 in the radial direction are of equal length, whereas in the contour 17 of the rod 9 according to Fig. 12 Projections 30 projecting further outward radially alternate with projections 31 projecting less far outward radially. As with the previous rods 9, the cross-section or contour 19 of the receptacle 16, which deviates from a circular shape, has adjacent sections 20, 21 in the circumferential direction, which alternately project more or less far radially inward.

[0049] At the bars 9 according to the Fig. 10 , Fig. 12 and Fig. 14 A clamping of the rod 9 in the holder 16 is also achieved by rotating the rod 9 in the circumferential direction.

[0050] To perform the rotation, the rod 9 has Fig. 10 As an engagement means, it has a hexagon socket contour 32 on the front side, which a corresponding hexagon socket tool can engage. The rod according to Fig. 12 has two slots 33, 34 arranged perpendicular to each other on the front side as an engagement means, into which the end of a corresponding screwdriver can engage.

[0051] It is still possible to implement the design according to the Fig. 1 bis 6 as clamping means as in the embodiment according to Fig. 14 four outwardly projecting projections 30 on the rod 9 or as in Fig. 10 adjacent sections 28, 29 projecting radially more or less far outwards.
