Definitions

• Drainage channel to be used for sanitation purposes
• the present invention relates to a drainage channel for sanitary applications, in particular a channel for showers, to be installed in a floor so that it is substantially flush with the upper surface of a floor covering, with two side walls, at least one bottom wall, an in particular deep-drawn outflow pot attached to the bottom wall to receive an odour trap, and a circumferential thin-bed flange for attachment of a surface covering to the drainage channel.
• the present invention relates to an odour trap to be installed in a drainage channel, in particular a shower drain, with an odour-trap pot to receive a sealing water and an odour-trap inlet element that is releasably attachable by way of a sealing upper edge to an outflow pot of the drainage channel and by way of a lower edge can be inserted into the odour trap through an upper side of the odour-trap pot so as to form a labyrinth odour trap.
• the present invention is thus directed towards the problem of developing a drainage channel or an odour trap of the kind mentioned above so that its manufacture is improved and simplified, the manufacturing costs are reduced and the apparatus can be better employed.
• This problem is solved by a drainage channel according to Claim 1 and by an odour trap according to Claim 13.
• this problem is solved by constructing a drainage channel of the above- mentioned kind so that the bottom wall, the side walls and the thin-bed flange in the region of the side walls are formed by bending a single sheet of metal.
• an odour trap that comprises at its pot at least one retaining lug and at its inlet element at least one connecting element with a retaining groove, or the reverse arrangement, so that when the inlet element of the odour trap is being inserted into the odour-trap pot, the retaining groove can be brought into releasable locking engagement with the retaining lug.
• a substantial advantage of constructing the above-mentioned drainage channel so that its side walls, bottom wall and thin-bed flange are all made from one metal sheet is, among other things, that it can be manufactured very economically and rapidly. It is thus possible, for example, to bring the drainage channel into its final shape with no need for time-consuming welding or similar jointing work. So that this drainage channel can, if necessary, be correspondingly closed on its narrow sides, all that is then necessary is to join on end-face side walls, for instance by welding, which on the whole results in a much more economical manufacturing procedure.
• Another advantage resides in the fact that in particular when the drainage channel is installed so as to be flush with the surface, a very much more uniform upper edge of the drainage channel can be ensured, because no partially very rough and irregular welded edges are present here. Especially for sanitary applications such a "round" upper edge is required of a drainage channel, so that in particular injuries associated with walking barefoot are prevented. Furthermore, the outflow behaviour is naturally also improved because of the continuity of the surface, particularly in that the deposition of dirt is avoided.
• the drainage channel and/or the odour trap is advantageously made of a metal, and in particular a non-rusting metal such as VA. Because such non-rusting metals place special demands on the welding technique, the integral construction of the drainage channel in the region of the side walls, bottom wall and thin-bed flange results in additional cost savings and more rapid production. However, it is of course also conceivable for the above-mentioned drainage channel to be made of a plastic material, for instance an artificial thermoplastic material.
• the thin-bed flange is spaced apart from the upper edge of the drainage channel in such a way that the surface covering to be attached to an upper side of the flange can be applied so that its upper surface is flush with the upper edge of the drainage channel where it adjoins the latter.
• the term surface covering is to be understood here as including every floor surface layer preferably used in the area of sanitation, for instance a plastic floor or a tile floor. Because the thin-bed flange is spaced apart from the upper edge of the drainage channel it is possible to apply a contact layer to this thin-bed flange and thus to dispose the surface covering so that its surface is flush with the drainage channel. Preferably this contact layer is elastic, so as to prevent the surface covering from becoming detached from the thin-bed flange.
• At least the upper surface of the flange is preferably sanded or coated with a similar bonding agent.
• this thin-bed flange also serves to stabilise the drainage channel underground, so that even when loads are imposed by movements above it, the drainage channel stays reliably positioned in its seating.
• the drainage channel comprises at least one element for altering its height and/or inclination, so that it can be adjusted to a desired height level and/or a desired degree of inclination with respect to the floor.
• This element enables the drainage channel to be adjusted to its future installation site in a targeted manner, which is particularly necessary in the context of sanitation because here a targeted and effective conduction of water from the surface covering into the drainage channel is demanded.
• the height-altering element and/or inclination-altering element comprises a standing flange that projects out of the drainage channel in a direction substantially perpendicular to the bottom wall and, attached thereto by at least one connecting element so that it can be shifted or pivoted, a mounting element for mounting on the floor.
• This projecting standing flange can be disposed both on the bottom wall of the drainage channel and also on the thin-bed flange or the side walls, and is preferably welded to the drainage channel.
• any other jointing technique known from the state of the art can also be employed.
• the standing flange to be integral with the drainage channel, in that a particular region of the thin-bed flange is bent downward and then functions as standing flange.
• the mounting element to receive the standing flange preferably comprises a longitudinal slot within which the standing flange together with the drainage channel can be seated and shifted longitudinally by way of a connecting element, for instance a screw.
• a connecting element for instance a screw.
• corresponding catch connections to be constructed between mounting element and standing flange, in order to ensure that the height and/ or inclination can be adjusted.
• the mounting element in turn is preferably screwed or attached by adhesive to the floor itself, in order to ensure a reliable positioning of the drainage channel even before the installation of the surface covering.
• the odour trap to be inserted into the outflow pot of the drainage channel preferably has a sealing-water height between 30 mm and 80 mm, in particular substantially 50 mm.
• the outflow pot of the drainage channel has the component dimensions necessary for it to correspond thereto.
• a sealing-water height in the above-mentioned range has proved to be especially effective when the drainage channel is in use, in particular in the sanitation context, and guarantees both an effective water conduction and also a reliable odour trap, even if the drainage channel is not in use for a relatively long time.
• the odour trap comprises an odour-trap pot to accommodate a sealing water and an odour-trap inlet element that can be tightly but releasably attached, by way of an upper edge, to the outflow pot of the drainage channel and, by way of a lower edge, can be introduced through an upper side of the odour-trap pot so as to form a labyrinth odour trap.
• an odour-trap pot to accommodate a sealing water and an odour-trap inlet element that can be tightly but releasably attached, by way of an upper edge, to the outflow pot of the drainage channel and, by way of a lower edge, can be introduced through an upper side of the odour-trap pot so as to form a labyrinth odour trap.
• outflow pot disposed on the drainage channel in particular a deep-drawn outflow pot
• a removable odour trap of the kind described above By combining the outflow pot disposed on the drainage channel, in particular a deep-drawn outflow pot, with a removable odour trap of the kind described above, one obtains a very compact drainage channel with a very small installation height, so that it can be installed even where only limited space is available.
• At least one retaining lug is disposed on the odour-trap pot and at least one connecting element with a retaining groove on the odour-trap inlet element, or conversely, so that when the odour-trap inlet element is being inserted into the odour- trap pot, the retaining groove can be brought into releasable locking engagement with the retaining lug.
• an odour trap is obtained that can be simply disassembled and reassembled, without using any additional tool, so as to carry out the appropriate cleaning operations at specified intervals and whenever it seems necessary.
• the retaining lug here is, for example, a rounded ridge that can be snapped into a correspondingly shaped retaining groove in the form of a ridge receptacle on the connecting element.
• the force threshold that must be crossed in order to release this engagement is preferably made such that the odour trap can be removed from the outflow pot of the drainage channel without releasing the engagement between odour-trap pot and odour-trap inlet element. Hence the odour trap can be removed as a whole from the drainage channel and then, if necessary, taken apart for cleaning.
• retaining groove on the odour-trap outflow pot instead of a retaining lug, and to dispose a correspondingly congruent retaining lug on the connecting element of the inlet element.
• retaining lugs and/or grooves can be made integral with the associated component or attached as a separate unit by means of appropriate attachment means such as are known in the state of the art.
• the retaining lug or groove is positioned on the upper side of the odour-trap pot, such that it extends in particular over the entire circumference of the odour-trap pot.
• the advantage of its covering the whole circumference is that the odour-trap inlet element can be set into and engaged with the inlet pot regardless of the inlet element's orientation with respect to the circumference of the pot.
• the odour-trap inlet element comprises at its upper edge a flange that extends substantially at a right angle thereto and serves to receive a connection gasket to seal the connection to the outflow pot of the drainage channel.
• the dimensions of this right-angle flange and the connection gasket disposed thereon are chosen so that they conform to the internal dimensions of the outflow pot of the drainage channel, so that the odour trap can simply be pushed into the outflow pot and then is seated in a secure and water-tight manner.
• connection gasket here includes all of the sealing elements known in the state of the art, which can be set onto the flange or held to it by appropriate connecting elements. However, it is of course also conceivable to design a connection gasket in such a way that the right-angle flange is not needed, and a direct mounting on the odour-trap inlet element can be performed.
• the connecting element runs along the odour-trap inlet element from an underside of the flange to an outer wall of the odour-trap inlet element.
• connecting element in this case, for example, a punched-out sheet of metal can be used, in which is formed the retaining groove or lug that is needed for locking to the odour-trap pot.
• several connecting elements are provided, which are uniformly distributed over the circumference of the odour trap.
• the attachment of the connecting element to the odour-trap inlet element in this case is preferably achieved by a stamped or welded connection, although it is of course also possible to employ corresponding releasable connection methods, so that when it becomes worn the connecting element can simply be exchanged.
• the connecting element can be pushed or clicked into a corresponding receptacle on the odour-trap inlet element.
• the connecting element is preferably made of an elastic material, in particular a flexible, thin metal sheet. This elastic construction not only enables reliable locking but also, if a releasable arrangement of the connecting element on the odour-trap inlet element is used, allows simple mounting in corresponding bearing elements on the inlet element.
• the present invention comprises not only a drainage channel with an odour trap of the kind described above, but also the odour trap itself, for installation in a drainage channel and in particular in a shower channel.
• the odour trap itself, for installation in a drainage channel and in particular in a shower channel.
• the structure of the odour trap and its particular embodiments because in its characteristics it corresponds to the odour trap that was described in the preceding paragraphs in connection with a drainage channel for sanitation purposes. In this regard reference is explicitly made to these passages.
• Fig. 1 shows a cross section through an embodiment of the drainage channel with deep-drawn outflow pot, transverse to a main direction of extent;
• Fig. 2 shows a plan view of the embodiment in Fig. 1;
• Fig. 3 shows a side view of the embodiment in Fig. 1 transverse to a main direction of extent
• Fig. 4 shows a cross section through an odour trap to be received in the outflow pot of the drainage channel shown in Fig. 1,
• Fig. 5 shows a more detailed section through the connecting region of two individual components of the odour trap in Fig. 5;
• Fig. 6 shows a plan view of the odour trap in Fig. 4.
• Figure 1 shows a cross section through a drainage channel 1 to be installed in a floor, for example a floor of a shower, so that the upper surfaces of channel and floor are flush with one another; the section is transverse to the main direction of extent of the drainage channel.
• the drainage channel 1 comprises a bottom wall 4, two side walls 2, 2' and a circumferential thin-bed flange 8, 8'.
• a crucial aspect of the invention is that the parts of the thin-bed flange 8, 8' shown in Fig. 1, the side walls 2, 2' and the bottom wall 4 are constructed by bending a single sheet of metal, so that no welding is required at the regions of transition from one element to another.
• the thin-bed flange 8, 8' serves to receive a floor surface covering (not shown) and in order to improve the bonding between said covering and the flange, the latter is provided with a layer 10 that promotes adhesion, for instance by sanding, which is applied to an upper side 9, 9' of the thin-bed flange 8, 8'.
• the drainage channel 1 is installed in such a way that the adjacent surface covering (not shown) is flush with an upper edge 12, 12'. Because the thin-bed flange 8, 8' and the side walls 2, 2' ate formed by bending a metal sheet, the upper edge 12, 12' is ideally smooth, one result of which is to prevent the deposition of dirt particles from the water that is to be conducted away from the surface.
• the thin-bed flange 8, 8' is spaced apart from the upper edge 12, 12' by an appropriate distance.
• an outflow pot 6 Integrally attached to the bottom wall 4 is an outflow pot 6, which allows the water that flows from the surface into the drainage channel to be conducted away, and in addition serves as a receptacle for an odour trap 20 (see Figs. 4-6).
• This outflow pot in this case is deep-drawn and welded to the drainage channel 1.
• FIG. 2 shows a plan view of the drainage channel 1 in which the circumferential thin- bed flange 8, 8', completely enclosing the drainage channel 1, is clearly visible.
• the two transverse ends of the drainage channel 1 are closed by end-face side walls 5, 5', which are welded both to the side walls 2, 2' and to the bottom wall 4.
• the outflow pot 6 is shown, with the odour trap 20 inserted into the outflow pot 6.
• FIG. 3 shows a side view of the drainage channel 1, perpendicular to the main direction of extent of the drainage channel 1.
• the outflow pot 6 is visible here, being attached to the bottom wall 4 and projecting downwards.
• a height-altering element 16, 16' is provided, which allows the drainage channel 1 to be adjusted to a desired height level with respect to a floor 3 on which the drainage channel is seated.
• the height-altering elements 16, 16' each comprise a standing flange 13, 13', which likewise projects out of the bottom wall 4 of the drainage channel 1 and in each case is joined to a mounting element 15, 15' by way of a connecting element 14, 14', for instance a screw; the mounting element has an angular shape and is seated on the floor 3.
• the mounting element 15, 15' preferably comprises a slot so that by loosening the connecting element 14, 14' the drainage channel 1 can be shifted over the standing flange 13, 13'. To enlarge the range in which shifting can occur it is possible in addition to provide a corresponding slot on the projection 13, 13'. Then after the connecting elements 14, 14' have been tightened, the drainage channel 1 is secured at that height level.
• this height-altering element 16, 16' to be used as a means of altering inclination, in which case after loosening of the connecting elements 14, 14' the drainage channel 1 can be pivoted perpendicular to the plane of the drawing.
• FIG. 4 shows the odour trap 20, which can be pushed into the outflow pot 6 so as to form a tight seal.
• the odour trap 20 comprises an odour-trap pot 22 into which, through an upper side 30, an odour-trap inlet element 24 can be inserted.
• water that is to be conducted out of the drainage channel 1 enters the odour-trap inlet element 24 by way of an inlet region 21 and, in the region of a lower edge 28, flows into the odour-trap pot 22, which collects a sealing water (not shown) until it is completely full, after which the sealing water flows over the upper side 30 and into the outflow pot 6, from which it is conducted away.
• the odour-trap pot 22 and the odour- trap inlet element 24 are matched to one another in such a way as to determine a maximal height h of the sealing water, which here preferably amounts to 50 mm.
• the odour-trap inlet element 24 comprises at an upper edge 26 a flange 38, which extends outward at a 90° angle to the main direction of extent of the odour-trap inlet element.
• a connection gasket 40, 40' is provided, which extends over the entire circumference of the flange 38 and enables the odour trap 20 to be inserted into the outflow pot 5 of the drainage channel 1 in a tightly sealed manner.
• the connection gasket 40, 40' is designed with multiple lips, but it goes without saying that all other gasket designs in current use can also be employed here.
• an odour trap eventually accumulates a deposit of dirt particles contained in the water that is to be conducted away, it must be cleaned at certain intervals.
• the present odour trap 20 is constructed in several parts, such that the odour-trap pot 22 and the odour-trap inlet element 24 can be separated from one another and thus enable the odour trap 20 to be completely cleaned.
• Figure 5 shows a means to this end, allowing the odour-trap pot 22 to be unlocked from the odour-trap inlet element 24.
• a retaining lug 32 is provided, which is releasably engaged with a retaining groove 36 in a connecting element 34, which itself is attached to the odour-trap inlet element 24.
• the connecting element 34 is disposed on an underside 42 of the flange 38 and at a perpendicular outer wall 44 of the odour-trap inlet element 24. In this case the connecting element 34 is welded to the odour-trap inlet element.
• the connecting element 34 is constructed as a flexible, thin sheet of metal, which creates or releases the connection between retaining lug 32 and retaining groove 36 when a specified locking force or releasing force, respectively, has been exceeded.
• This arrangement makes it possible for the odour trap 20 to be completely disassembled, enabling effective cleaning.
• This releasing/locking-force threshold is here chosen to be below the force necessary to pull the odour trap 20 out of the outflow pot 6. As a result, it is ensured that the odour trap 20 can be removed as a whole from the outflow pot 6 of the drainage channel 1.
• FIG. 6 a plan view of the odour trap 20, shows how the odour-trap inlet element 24 is connected to the odour-trap outflow pot 22 by way of the connecting elements 34.
