[0001] The invention relates to a drain. Drains are available in numerous embodiments. Apart
from having different lengths, a drain may optionally be further provided with a flange
for fixing of a sealing membrane. This flange can further also be bent upward for
arrangement against a wall.
[0002] Because of all these variations a supplier or manufacturer has to hold a large number
of different drains in stock. This requires considerable storage space.
[0003] A sealing membrane can further be arranged on the flange, or the flange can be sand-coated.
This results in even more variations.
[0004] In order to also provide a space-saving solution for the variations with or without
sealing membrane it is known to provide drains with a flange and, subject to demand,
to optionally also supply a separate sealing membrane. The plumber him/herself then
has to arrange the sealing membrane during installation of the drain. This however
increases the chance of errors, and therefore the chance of leakage. It is therefore
recommended to provide a drain with a sealing membrane in the factory, even though
this involves the necessity of extra storage space.
[0005] It is an object of the invention to reduce or even obviate the above stated drawbacks.
[0006] This object is achieved according to the invention with a drain comprising:
- a collecting tray provided with a bottom with an outflow and upright walls arranged
along the bottom;
- a flange plate arranged against the bottom of the collecting tray, wherein the flange
plate is provided with an opening for passage of the outflow.
[0007] Arranging a separate flange plate thus makes it possible using a single collecting
tray to provide either a drain without flanges or a drain with flanges.
[0008] The manufacturer or supplier can thus stock collecting trays of different lengths
and, in addition, a number of flange plates of different lengths. Subject to the demand
for a drain with flange, a collecting tray of a desired length and a corresponding
flange plate can then be taken from the storage location. It is thus no longer necessary
to stock a determined length of a drain without flanges as well as of a drain with
flanges.
[0009] Another advantage of the two separate components is that acid treatment of the drain
is easier and that there are no cavities between the fixed flange and collecting tray
in which acid may remain as in the prior art.
[0010] A further advantage is that bending of the separate collecting tray and the separate
flange plate is considerably simpler.
[0011] Finally, the flange plate and the collecting tray can be made from different materials.
The collecting tray can for instance be made from the usual stainless steel, while
the flange plate can be made of plastic or galvanized iron.
[0012] The flange plate preferably extends on at least one side beyond the bottom of the
collecting tray in order to form a flange.
[0013] When the flange extends beyond the bottom, the flange can be used in simple manner
to level the surrounding floor for the purpose of manually arranging a sealing membrane,
or the flange can serve as anchor for the collecting tray.
[0014] In an embodiment of the drain according to the invention the flange plate is adhered
to the bottom, for instance by means of a sealant or a double-sided adhesive tape.
[0015] A foam layer with an adhesive layer on both surfaces is preferably arranged between
the flange plate and the bottom. A foaming sealant or glue can also be used.
[0016] The foam plate or foam layer first and foremost provides for the adhesion of the
flange plate to the bottom of the collecting tray, but in addition provides sound
insulation. When water falls into the collecting tray the sound can usually be transmitted
easily into the floor. This is at least partially prevented by the sound-insulating
effect of the foam plate.
[0017] In a preferred embodiment of the drain according to the invention the flange plate
has a recessed middle part for accommodating the bottom of the collecting tray.
[0018] When relatively thin floor tiles are used on the surrounding floor, it may be the
case that the depth of the collecting tray is greater than the thickness of the tiles.
By now providing the flange plate with a recess, the resulting flanges will lie higher
than the bottom of the collecting tray.
[0019] Also in the case a tile is used as grating in the collecting tray the depth of the
collecting tray will always be greater than the thickness of the tile.
[0020] In another embodiment of the drain according to the invention the flange plate comprises
at least one flange standing at a right angle. The right-angled flange has to be arranged
against the wall.
[0021] When the upright flange is however not arranged against the wall, it can also serve
as anchor for the collecting tray by incorporating the upright flange into the sub-floor.
[0022] In yet another embodiment of the drain according to the invention the flange plate
has at least one edge sloping away in downward direction.
[0023] The downward sloping edge can be embedded in the surrounding floor, whereby the drain
is anchored. A firm fixing of the drain in the floor is thus obtained.
[0024] In a further preferred embodiment of the drain according to the invention a filler
part is arranged along the edge of the flange plate.
[0025] The filler part preferably comprises a foam layer and a finishing layer, such as
a thin steel sheet.
[0026] The filler part makes it possible to determine at the last moment which finishing
layer will be arranged adjacently of the drain. If a thin finishing layer is chosen,
a fitting filler part can be provided on the flange, after which the floor can be
levelled and the finishing layer arranged. The height of the upper edge of the collecting
tray can thus be adapted to the upper surface of the finishing layer.
[0027] In yet another embodiment of the drain according to the invention the flange plate
comprises at least one tongue which is bent out of the surface of the flange plate.
[0028] The tongue bent out of the surface can be used as adjusting foot for the drain. In
addition, the tongue can be embedded in the underlying floor, thereby anchoring the
drain.
[0029] In yet another embodiment of the drain according to the invention a sealing membrane
is arranged on the flange plate.
[0030] It is further possible in a drain according to the invention for at least a part
of the flange plate to be sand-coated.
[0031] These and other features of the invention are further elucidated with reference to
the accompanying drawings.
Figure 1 is a perspective view of a first embodiment of the drain according to the
invention.
Figure 2 is a perspective cross-sectional view of a variant of the drain according
to figure 1.
Figure 3 is a perspective cross-sectional view of a second embodiment of the drain
according to the invention.
Figure 4 is a perspective cross-sectional view of a third embodiment of the drain
according to the invention.
Figures 5 and 6 are cross-sectional views of a fourth and a fifth embodiment.
Figure 7 is a perspective view of a flange plate for a drain according to the invention.
[0032] Figure 1 is a perspective view of a first embodiment of a drain 1 according to the
invention. Drain 1 has a collecting tray 2 which is connected with an outflow to a
siphon 3. Arranged around collecting tray 2 is a horizontal flange 4 which is provided
along one long side with a vertical flange part 5 for fixing against a wall. A grating
6 is further arranged in collecting tray 2.
[0033] Figure 2 shows a variant 10 of drain 1 according to the invention. This variant 10
has a collecting tray 11 with an outflow 12.
[0034] Arranged against the underside of collecting tray 11 is an adhesive tape 13 against
which a flange plate 14 is adhered. Flange plate 14 is provided with a vertical flange
part 15 for fixing against a wall.
[0035] A so-called tile tray 16 is placed in collecting tray 11. A floor tile can be placed
herein. In order to now reduce the height difference between flange plate 14 and the
upper side of a tile tray 16, filler parts 17, 18 are arranged on the flange plate
in this embodiment. These filler parts 17, 18 are finished on the upper side with
thin metal sheeting 19.
[0036] Figure 3 shows a second embodiment 20 of the drain according to the invention. A
flange plate 22 is here also arranged under a collecting tray 21. A tile tray 23 is
here also arranged in collecting tray 21, and a filler part 24 is provided on flange
plate 22 to reduce the height difference with tile tray 23.
[0037] Figure 4 shows a third embodiment 30 of the drain according to the invention. This
drain 30 has a collecting tray 31 with an outflow 32. Arranged around this outflow
32 and against the underside of collecting tray 31 is a flat flange plate 33.
[0038] A more usual grating 34 is arranged in collecting tray 31. Owing to the relatively
small height of grating 34, filler parts are not required in this embodiment.
[0039] Figure 5 shows a cross-section of a fourth embodiment 40 of the drain according to
the invention. This drain 40 once again has a collecting tray 41 with an outflow 42.
Arranged against the underside of collecting tray 41 is a foam layer 43 which provides
for sound insulation. Against this is adhered a flange plate 44. This flange plate
has a downward sloping edge which can be incorporated into the surrounding floor and
thereby provides for an anchoring of drain 40.
[0040] Figure 6 shows a fifth embodiment of a drain 50 according to the invention. Here
too a foam layer 53 and a flange plate 54 are arranged against collecting tray 51
with outflow 52. Flange plate 54 is provided with a stepped flange, whereby the height
difference between flange 54 and the upper side of collecting tray 51 can be reduced.
[0041] It is conversely also possible to increase the distance by arranging flange plate
54 upside down against the collecting tray.
[0042] Figure 7 is a perspective view of a flange plate 60. Provided in the centre of flange
plate 60 is an opening 61 for passage of an outflow of a collecting tray.
[0043] Edge 62 of opening 61 is bent outward so that the usual weld between the outflow
and the bottom of the collecting tray can be accommodated and flange plate 60 can
lie closely against the bottom of the collecting tray.
[0044] Further provided in flange plate 60 are tongues 63 which can be bent out of plate
60 and can serve as adjusting foot or as anchor.
