Abstract
Description
- The present invention relates to an elevating device for floor drains, which device comprises an elevating member directed upwards from the floor drain and a flange member provided on top of said elevating member.
- When a floor is cast, the floor drain is usually located somewhat too low for not risking that it protrudes above the floor and thereby obstructs the flow of water down into the floor drain. The floor drain must thereafter often be provided with an elevating device, the flange of which is located flush with the floor level such that a floor mat via the elevating device can be connected to the floor drain with the required sealing.
- Elevating devices are also used when a new floor is cast on top of an existing floor. Hereby, the elevating device is placed close to the floor drain provided in the existing floor, whereby a flange member of the elevating device is brought flush with the new floor level. Hereby, the floor mat on the new floor level can be brought down into the flange member and secured close thereto by means of a clamping ring. In this way, water can flow down into the floor drain, although the floor level is raised above the drain. Elevating devices with this function are already known from e.g. applicant's own SE 343 358.
- However, it has been noticed that one must manufacture and store several different types of elevating devices in order to cover the present need, since elevating devices with a certain height fit into floor layers with a certain thickness, but not into floor layers with another thickness.
- The object of the present invention is to eliminate this problem and provide an elevating device which is easily adaptable to the floor level in question and to all existing thicknesses of new floor layers. This is arrived at according to the invention substantially while the elevating device defined above has the characterizing features of subsequent claim 1.
- Since according to the invention the elevating member can be cut at the top and the flange member thereafter mounted on the cut elevating member, one and the same elevating device can be adapted to the floor level in question and to the thickness of new floor layers irrespective of said layers being thick or thin. The threads provided on the elevating member prevent the flange member from being pulled off the elevating member. It is also possible to compensate the total height of the elevating device if too large a portion of the elevating member is cut off.
- The invention will be further described below with reference to the accompanying drawings, wherein
- fig. 1 is a vertical section through a floor drain with the members of the elevating device according to the invention brought apart;
- fig. 2 is an identical section through the same members put together;
- fig. 3 is a plan view from below of a portion of a flange member forming part of the elevating device of fig. 1;
- fig. 4 is a plan view of a mounting member forming part of the elevating device of fig. 1; and
- fig. 5 is a vertical section through an alternative embodiment of the elevating device according to the invention.
- In figs. 1 and 2 there is shown a floor drain 1 having an upwardly open through-
flow member 2 for letting in water from above and which preferably has a circular or substantially circular cross section. A laterally directedoutlet pipe member 3 extends from the through-flow member 2, whereby thebottom portions 4 of the through-flow member 2 and thebottom portions 5 of the laterally directedoutlet pipe member 3 in this embodiment are situated at the same level. - The
elevating device 6 belonging to the floor drain 1 includes anelevating member 7 and aseparate flange member 8. Theelevating member 7 is here integral with the floor drain 1 and made in one piece therewith. This elevatingmember 7 preferably has a circular or substantially circular cross section and the same diameter as the through-flow member 2. Theelevating member 7 extends upwards from the through-flow member 2 and it has an original height UH. Theflange member 8 is in this case adapted to be mounted on theelevating member 7 through amounting means 9 after said elevatingmember 7 has been cut with a suitable tool, e.g. a saw, such that its original height UH has been reduced to a desired height H. The elevatingmember 7 is preferably cut in those upper portions provided withthreads 10 and preferably along a section at the bottom of one of theexternal threads 10. - The
external threads 10 of theelevating member 7 begin at theupper edge 11 of saidmember 7 and extend to a level adjacent abottom portion 12 of such arecessed part 13 ofupper portions 14 of the laterally directedoutlet pipe member 3 which is situated closest to theelevating member 7. Hereby, it is possible to cut theelevating member 7 at the level LN flush with or substantially flush with theupper portions 14 of the laterally directed outlet pipe member 3 (which means that the floor drain becomes very low), since there are stillexternal threads 10 below this level LN to screw on theflange member 8 through the mounting means 9. If there is no suchrecessed part 13, theexternal threads 10 may end flush with or substantially flush with theupper portions 14 of theoutlet pipe member 3. - The
external threads 10 are thus provided such that theflange member 8 through the mounting means 9 can be screwed onto thethreads 10 left on the remaining part of theelevating member 7 after cutting thereof to the desired height H. - Preferably, the mounting means 9 is connectable to the flange member 8 (or vice versa) such that said
flange member 8 and mounting means 9 form a unit. To enable this interconnection, theflange member 8 includes axially directed snap-inportions 15 and the mounting means 9 axially directed snap-inportions 16. These snap-inportions flange member 8 and mounting means 9 together, and such that said flange member and mounting means thereafter can not be rotated relative to each other. Theflange member 8 has e.g. eight snap-inportions 15 shaped asprotrusions 17 of which each has an upwardly/outwardlyinclined surface 18 which at the top is attached to ahorizontal surface 19. The mounting means 9 has eight snap-inportions 16 shaped asrecesses 20 into which theprotrusions 17 of theflange member 8 fit. Eachrecess 20 is open in inwards direction, is somewhat wider than the associatedprotrusion 17 and has at the top a horizontally directedtongue 21 which transforms into a downwardly directedportion 22. Therecess 20 is laterally limited bywall portions tongue 21 and the downwardly directedportion 22 with portions of the mounting means 9 provided within saidtongue 21 and downwardly directed portion 22 (see fig. 4). Snap-in locking of theflange member 8 and mounting means 9 to each other is carried out by threading the mounting means 9 onto the flange member 8 (or vice versa) so that theprotrusions 17 of theflange member 8 slide into therecesses 20 of the mounting means 9. Since those portions of the mounting means 9 which define therecesses 20 are flexible, theflexible tongue 21 can snap in behind thehorizontal surface 19 of theprotrusion 17, whereby theflange member 8 and mounting means 9 are locked to each other. - The
flange member 8 also has an annular shape and comprises anupper flange 25 which is somewhat inclined in inwards direction and which deflects downwards and transforms into a downwardly directedportion 26 on the outside of which theprotrusions 17 are located. The downwardly directedportion 26 transforms down below into an inwardly directedportion 27, the outside of which is adapted to engage theupper edge 11 of theelevating member 7 and the inside of which is adapted to define a seat surface for aclamping ring 28. Thisclamping ring 28 is adapted to clamp afloor mat 29 which is bent down into theflange member 8 such that sealing is obtained between saidfloor mat 29 andflange member 8. The inwardly directedportion 27 of theflange member 8 transforms into alower portion 30 which down below is provided with aseat 31 for asealing ring 32. Thislower portion 30 can be brought down into theelevating member 7, whereby thesealing ring 32 sees to that sealing is obtained between theflange member 8 and the inside of theelevating member 7. - The mounting means 9 has an
internal thread 33 and when thisthread 33 during insertion of theflange member 8 into the elevatingmember 7 reaches theexternal threads 10 of saidelevating member 7, the mounting means 9 can be screwed onto the elevatingmember 7 by rotating theflange member 8 and thereby also saidmounting means 9, which thus operates as a nut means. The screwing of theflange member 8 onto theelevating member 7 can continue until the outside of the inwardly directedportion 27 of saidflange member 8 engages theupper edge 11 of said elevating member 7 (see fig. 2). - After the elevating
member 7 has been cut to the desired height H and the floor drain 1 located in the desired position relative to the floor level 34 (see fig. 2), theflange member 8 is moved down into theelevating member 7 and rotated to be screwed onto saidelevating member 7 by means of the mounting means 9. When theflange member 8 in this way is brought into the desired position relative to thefloor level 34, thefloor mat 29 is bent down into theflange member 8 and attached thereto by means of theclamping ring 28. - A
waterseal insert 35, i.e. an insert including a waterseal, can be provided on theflange member 8. Such waterseal inserts are known per se and can alternatively be mounted in the floor drain 1 in other ways. On top of theclamping ring 28 there is normally provided a grating (not shown) for letting water but not larger objects into the floor drain. - The alternative
elevating device 36 illustrated in fig. 5 is adapted for use in connection with casting (or in other ways forming) anew floor 37 on top of an already existingfloor 38 with afloor drain 39 having aflange portion 40. In this case theelevating device 36 includes a separateelevating member 41 which can be mounted on thefloor drain 39. In order to make this possible, theelevating member 41 has alower coupling portion 42 which is insertable into theflange portion 40 of thefloor drain 39, preferably until it with an end edge engages an inwardly directed wall portion down below at theflange portion 40. Thecoupling portion 42 can be fixed to the flange portion in any suitable way, e.g. by snap-in locking, such that a strong grip therebetween is obtained. In order to provide the required sealing, thelower coupling portion 42 can include an outer sealing ring 43 which is adapted to sealingly engage theflange portion 40. Thelower coupling portion 42 of theelevating device 36 preferably has no threads, but the remaining parts from saidportion 42 to theupper edge 11 of theelevating member 41 havethreads 10 in the same way as theelevating member 7. Theflange member 8 used at the elevatingmember 7 and the mounting means 9 used at theelevating member 7, can also be used at theelevating member 41. - In this case, the
elevating member 41 is cut to a desired height H which is depending on the thickness of thenew floor 37. - At the alternative device according to fig. 5, either a
waterseal insert 35A is located at theflange portion 40 of the floor drain already present or a waterseal insert 35B is located at theflange member 8. - Regarding the mounting means 9 it should be mentioned that it preferably also has an
inner edge 44 which is adapted to engage the outside of the inwardly directedportion 27 of theflange member 8 when the mounting means 9 is locked by a snap-in action to theflange member 8, whereby saidmounting means 9 can be brought to a locking engagement with theflange member 8 without clearance is axial direction. - The
elevating members - The
flange member 8 can preferably be screwed onto theelevating member elevating member flange member 8 in upwards direction on theelevating member - The invention is not limited to the embodiment described above and illustrated in the drawings, but may vary within the scope of the following claims. Thus, it should be noticed that the floor drain as well as the elevating device can be made of plastic or eventually of metal, the floor drain can be of another type than shown, the flange member can be screwed directly onto or in any other way directly positionable on the elevating member instead of using a mounting means; if a mounting means is used, said mounting means can be attached to the elevating member in any other way than by screwing, the elevating member can be shaped in another way than shown, the elevating member can be cut by means of a saw or by treatment in other ways with other tools, the flange member and mounting means can have another shape than shown and the mounting means can have a thread with only one turn or eventually several threads if required.
