Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This nonprovisional application claims priority from
European Patent Application No. 05001644.3 filed with the European
Patent Office on Jan. 27, 2005, the entire contents of which are
hereby incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] The disclosure relates to a sanitary fitting with a
pivotable water outlet, achieved by the below described
embodiments.
[0003] Sanitary fittings for discharging water, in particular a
mixture of cold water and hot water, are generally known. Sanitary
fittings are usually equipped with a pivotable water outlet for the
purpose of directing the mixed water, which flows out of the
sanitary fitting, to various regions of the surroundings.
[0004] A sanitary fitting with a pivotable water outlet of this
type is disclosed in DE-A-4138938, for example. The sanitary
fitting described in that document has an attachment base into
which water supply lines are routed, a control cartridge, and an
outlet pipe which can be pivoted about the central axis of a base
body of the fitting. The outlet pipe is attached to a fitting
sleeve which is mounted on the base body of the fitting such that
it can rotate. The mixed water passes from the control cartridge to
the base body of the fitting through a through-passage, continues
through a driver bushing, which is formed in a bearing recess in
the base body of the fitting, via an angled pipe element which is
attached to the inside of the sleeve together with the outlet pipe,
and leaves the sanitary fitting via the outlet pipe.
SUMMARY OF THE INVENTION
[0005] An object of the disclosed embodiments is to provide a
sanitary fitting of simple design which prevents the undesirable
discharge of water over a long period of time, even when its water
outlet is pivoted frequently, and which is cost-effective to
produce.
[0006] This object is achieved by a sanitary fitting comprising a
control cartridge having an input end connected to a water inflow
and an output end connected to an outflow-end through-passage which
is formed in a base body of the fitting and has a bearing recess; a
unipartite angled pipe element which forms a flow connection with
the outflow-end through-passage, can be pivoted about a pivot axis,
and is equipped with at least one water-bearing pipe limb; and a
water outlet which forms a flow connection with the angled pipe
element and can be pivoted about the pivot axis together with the
angled pipe element, wherein the water-bearing pipe limb is formed
on the unipartite angled pipe element at an inflow end, is oriented
at least virtually parallel to the pivot axis, and an inflow-end
end region engages in the bearing recess wherein the water-bearing
pipe limb can rotate. Particularly preferred embodiments are
described below.
[0007] The sanitary fitting according to the invention is equipped
with a control cartridge which is seated on a base body of the
fitting and is used to control an outflow of water, in particular
of mixed water, from the sanitary fitting. At the output end of the
control cartridge, the mixed water is passed through an outflow-end
through-passage in the base body of the fitting into an inflow-end
pipe limb of a unipartite angled pipe element. The angled pipe
element forms a flow connection with a water outlet through which
the mixed water flows out to the surroundings. On account of the
unipartite design of the angled pipe element, it is particularly
straightforward, for example using injection molding technology,
and thus very cost-effective to produce.
[0008] In the direction toward the angled pipe element, the
outflow-end through-passage is equipped with a bearing recess in
which the inflow-end pipe limb is mounted such that it can rotate
about a pivot axis. In this case, the longitudinal axis of the
inflow-end pipe limb runs coaxially to the pivot axis. The water
outlet which is connected to the angled pipe element can also be
pivoted about the pivot axis together with the inflow-end pipe
limb. The fact that the inflow-end pipe limb is mounted in the
bearing recess such that it can rotate prevents the need for
further connecting elements to be installed between the base body
of the fitting and the angled pipe element, and this in turn
reduces production costs. At the same time, this makes it possible
to insert a single dynamic sealing element into the bearing recess
between the inflow-end pipe limb and the base body of the fitting.
The dynamic sealing element is protected against environmental
influences in the bearing recess and has relatively small
dimensions in relation to the sanitary fitting. On account of its
small dimensions, the dynamic sealing element can be produced in a
cost-effective manner with lower tolerances and seals more reliably
with a longer service life than comparatively large sealing
elements.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Particularly preferred embodiments of the sanitary fitting
according to the invention are described below with reference to

form:
[0010] FIG. 1 shows a longitudinal section through a sanitary
fitting according to the invention with a pivotable angled pipe
element and a water outlet connected to said angled pipe
element;
[0011] FIG. 2 shows a cross section through the pivotable water
outlet of the sanitary fitting shown in FIG. 1 with a rotatable

[0012] FIG. 3 shows a cross section along plane III-III of the

[0013] FIG. 4 shows a cross section through a further embodiment of
an inventive sanitary fitting which is intended to be fitted to a
wall.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] The inventive sanitary fitting which is shown in
longitudinal section in FIG. 1 is designed for platform
installation. In this respect, the sanitary fitting has an
installation sleeve 12, which has an external thread (not shown in
FIG. 1), in its lower end region which faces a water inflow 10 of
the sanitary fitting. In order to install the sanitary fitting, the
installation sleeve 12 is passed through a corresponding passage in
a base, for example in a washstand, and is secured using a union
nut which can be screwed onto the external thread of the
installation sleeve 12 at the base end.
[0015] The water inflow 10 for cold water KW and/or hot water WW,
which water inflow is realized by feed pipes and is passed through
the installation sleeve 12, is connected to a corresponding
pipeline system for supplying water at the upstream end. At the
downstream end, the water inflow 10 passes through a bearing plate
14 arranged above the installation sleeve 12 and is inserted in a
sealed manner into an inflow-end through-passage 16 of a base body
18 of the fitting which is arranged above the bearing plate 14. To
this end, the feed pipes of the water inflow 10 are soldered,
welded, screwed or adhesively bonded into the inflow-end
through-passage or through-passages 16.
[0016] The inflow-end through-passage 16 routes the cold water KW
and/or the hot water WW to the input of a control cartridge 20. A
control cartridge 20 of this type is described in CH-A-691134, for
example. The control cartridge makes it possible for manual
intervention by a user and/or technical actuating means firstly to
control a mixing ratio of cold water KW and hot water WW which is
supplied via the water inflow 10 in order to provide mixed water
MW, and secondly to adjust the throughflow rate of the mixed water
MW which flows out through the sanitary fitting. The temperature of
the mixed water MW which flows out is determined by controlling the
mixing ratio of cold water KW to hot water WW.
[0017] The control cartridge 20 is fitted in a sealed manner on a
seat 28 of the base body 18 of the fitting, which seat is arranged
opposite the water inflow 10. At the output end of the control
cartridge 20, the mixed water MW is discharged through an
outflow-end through-passage 30 in the base body 18 of the fitting.
Therefore, at the input end, inflow-end through-passages 16 in the
base body 18 of the fitting for cold water KW and hot water WW,
and, at the output end, the outflow-end through-passage 30 in the
base body 18 of the fitting for mixed water MW communicate in terms
of flow with associated inputs and an output of the control
cartridge 20.
[0018] The control cartridge 20, the base body 18 of the fitting,
the bearing plate 14 and the installation sleeve 12 are arranged in
a hollow-cylindrical inner sleeve 32 and here are supported against
one another and fixed in their position relative to one another. A
similarly cylindrical outer sleeve 36 of the fitting surrounds the
inner sleeve 32 concentrically with respect to said inner sleeve
32.
[0019] In each of its free end regions, the outer sleeve 36 of the
fitting is mounted on the outside of the inner sleeve 32 such that
it can pivot about the coaxial cylinder axes of the outer sleeve 36
of the fitting and the inner sleeve 32 by means of sliding rings
38. An outlet connection piece 40 of a water outlet 42 which will
be described in detail below and which points away from the pivot
axis S is integrally formed on the outer sleeve 36 of the
fitting.
[0020] A cylindrical bearing recess 44 is formed in a downstream
end region in the outflow-end through-passage 30 in the base body
18 of the fitting. An inflow-end end region of an inflow-end pipe
limb 46, which is formed on a unipartite angled pipe element 48,
engages in the bearing recess 44 such that it can rotate or pivot
about a pivot axis S. The pivot axis S is defined by the cylinder
axes of the inflow-end pipe limb 46 and the outer sleeve 36 of the
fitting. Said pivot axis S coincides with the cylinder axes of the
inner sleeve 32 and bearing recess 44.
[0021] A dynamic sealing element in the form of a sealing ring 49
is arranged in the bearing recess 44 between the inflow-end end
region of the inflow-end pipe limb 46 and the base body 18 of the
fitting. The sealing ring 49 prevents mixed water MW from escaping
from the inflow-end pipe limb 46 to the bearing recess 44 and is
the only sealing element which is dynamically loaded when the
inflow-end pipe limb 46 or the water outlet 42 connected to said
pipe limb is pivoted.
[0022] On account of this single dynamic sealing element, the
internal construction of the sanitary fitting can be simplified and
it is possible to produce the sanitary fitting in a cost-effective
manner. Furthermore, the single dynamic sealing element is arranged
within the inner sleeve 32 in the case of the sanitary fitting
according to the invention, as a result of which it is possible for
the dynamic sealing element to have a smaller diameter in
comparison to known sanitary fittings with an annular channel.
Since sealing elements with smaller dimensions can be produced
within smaller tolerances and with lower production costs, the
service life is increased and the cost of producing the sanitary
fitting according to the invention is also reduced.
[0023] A bearing journal 50 is integrally formed on that end region
of the inflow-end pipe limb 46 which is opposite the bearing recess
44. This cylindrical bearing journal 50 engages in a bearing-like
recess 52 in the bearing plate 14, which recess is arranged
centrally with respect to the pivot axis S, such that it can
rotate. At the same time, the inflow-end pipe limb 46 is axially
supported by the bearing plate 14. As a result, one end of the
inflow-end pipe limb 46, and furthermore of the entire angled pipe
element 48, is mounted in the bearing recess 44 in the base body 18
of the fitting and the other end is mounted in the bearing-like
recess 52 in the bearing plate 14 such that they can rotate.
[0024] The mixed water MW flows from the inflow-end pipe limb 46
into an outflow-end pipe limb 54 of the angled pipe element 48
which projects away from the pivot axis S. In this case, the
cylinder axis of the inflow-end pipe limb 46, which cylinder axis
runs coaxially with respect to the pivot axis S, forms a fixed
angle of between 80.degree. and 90.degree., preferably of
80.degree., with the cylinder axis of the outflow-end pipe limb 54.
The two pipe limbs 46, 54, and furthermore the entire angled pipe
element 48, are produced from a plastic, preferably from polyacetal
(POM).
[0025] In the outflow-end pipe limb 54, a connection pipe 56 of the
water outlet 42 is joined in a sealed manner to said outflow-end
pipe limb 54 up to a shoulder 58. In order to prevent undesirable
discharge of mixed water MW in a corresponding join region, in
which, axially with respect to their longitudinal axes, the free
end region of the outflow-end pipe limb 54 accommodates the pipe
limb-end end region of the connection pipe 56 in the manner of a
sleeve, an O-ring 60 in the form of a static sealing element is
arranged in a groove in the pipe limb-end end region of the
connection pipe 56.
[0026] The connection pipe 56 is routed coaxially in the outlet
connection piece 40 through a guide ring 62 which is formed inside
the outlet connection piece 40. The connection pipe 56 issues at
the downstream end into an outlet channel 64 in an outlet end piece
66 which is mounted in the free end region of the outlet connection
piece 40. The outlet end piece 66 is produced from a plastic,
preferably from acrylonitrile-butadiene-styrene (ABS).
[0027] The outlet end piece 66 is mounted in the outlet connection
piece 40 such that it can rotate about an axis of rotation D. In
this case, the axis of rotation D is defined by the coaxial
cylinder axes of the connection pipe 56 and of the outlet
connection piece 40.
[0028] The outlet end piece 66 is rotatably mounted by inserting a
connection pipe-end pipe extension 68, which is formed on the
outlet end piece 66, into the free end region of the outlet
connection piece 40 with an accurate fit at the longitudinal end.
In addition to the ability of the water outlet 42 to pivot with
respect to the pivot axis S, the ability of the outlet end piece 66
to rotate with respect to the axis of rotation D provides an
additional degree of freedom for spatially orienting the mixed
water MW which flows out.
[0029] The connection pipe 56 is sealed off in the outlet end piece
66 by a radially inner wall 69 of the pipe extension 68 bearing
against the connection pipe 56 with an accurate fit and
simultaneously in a sealed manner, assisted by a static sealing
element which is in the form of a further O-ring 72 and is arranged
radially on the outside of the connection pipe 56 in a groove
70.
[0030] As shown in FIG. 2, a rotation angle about the axis of
rotation D may be restricted to a range of approximately
-60.degree. to +60.degree. and therefore to a total of
approximately 120.degree.. To this end, a stop screw 74 is screwed
into the free end region of the outlet connection piece 40. A
further groove 76 which is accommodated radially on the outside of
the pipe extension 68 and covers virtually half of the
circumference allows the outlet end piece 66 to rotate about the
axis of rotation D until the stop screw 74 extending into the
groove 76 limits the rotation angle by striking stop faces 78 which
are formed at each end of the groove 76.
[0031] In the outlet end piece 66, the outlet channel 64 for the
mixed water MW opens through a water outlet opening 80 which is
oriented perpendicularly to the axis of rotation D. The water
outlet opening 80 is provided with an internal thread which
interacts with an external thread of a nozzle 82 which can be
screwed into the water outlet opening 80. Various types of
jet-forming elements or filter elements may be inserted into the
nozzle 82 (not shown in section in FIG. 1) before the mixed water
MW is discharged to the surroundings.
[0032] A filter element in the form of a legionella filter 84 is
inserted directly in or close to the water outlet opening 80 in the
outlet channel 64 in the outlet end piece 66 such that it can be
replaced. Legionellae (rod-shaped bacteria which cause
Legionnaire's disease) which may possibly be entrained with the
mixed water MW from the connection pipe 56 are killed by the
legionella filter 84 which is in the form of a metal grating coated
with a layer of silver. The arrangement of the legionella filter 84
in the immediate vicinity of the water outlet opening 80 also
prevents recontamination of water-bearing elements which are
arranged upstream of the water outlet opening 80.
[0033] In the outlet end piece 66, a transparent window 86 is
arranged diametrically opposite the water outlet opening 80 with
respect to the axis of rotation D. The transparent window 86, which
is produced from a plastic, preferably from Plexiglas (polymethyl
acrylate), provides a view of the legionella filter 84 which is
arranged in the outlet channel 64, and thus allows the state of the
legionella filter 84 to be visually monitored. When the silver
layer of the legionella filter 84 is suitably discolored, the
outlet end piece 66 may be withdrawn from the outlet connection
piece 40 after the stop screw 74 is removed by being unscrewed, and
the used legionella filter 84 which is inserted in the outlet
channel 64 may be replaced.
[0034] Like the rotation angle of the outlet end piece 66 about the
axis of rotation D, a pivoting angle of the water outlet 42 about
the pivot axis S is also limited. To this end, as shown in the
sectional illustration in FIG. 3, a stop pin 88 is inserted into
the base body 18 of the fitting such that it passes through the
inner sleeve 32 radially. Stops 90 which are formed radially on the
inside of the outer sleeve 36 of the fitting interact with the stop
pin 88 projecting into a space between the outer sleeve 36 of the
fitting and the inner sleeve 32, and limit the pivoting angle in a
range of approximately -40.degree. to approximately
+40.degree..
[0035] As shown in FIG. 3 in particular, neither the outer sleeve
36 of the fitting nor the outlet connection piece 40 bears water.
For this reason, dynamic sealing elements which have a large
diameter and are associated with the outer sleeve 36 of the fitting
can be dispensed with completely, construction can be simplified,
and the sanitary fitting according to the invention can therefore
be produced in a cost-effective manner.
[0036] In the sectional diagram of FIG. 3, the cut-away,
hollow-cylindrical inner sleeve 32 has a semicircular half-ring
which is open toward the pivot axis S and is interrupted only by
the stop pin 88. At the connection-pipe end, opposite the cut-away
half-ring, there is a recess in the inner sleeve 32, which recess
is needed to enable the outflow-end pipe limb 54 of the angled pipe
element 48 and the connection pipe 56 to pivot.
[0037] The base body 18 of the fitting, in which base body circular
through-passages of the water inflow 10 for cold water KW and hot
water WW are shown, is also open toward the pivot axis S on account
of a wedge-shaped recess which is needed to allow the angled pipe
element 48 and the connection pipe 56 to pivot. The inflow-end pipe
limb 46, which is rounded on the outside in the sectional diagram,
of the cut-away angled pipe element 48, which is also wedge-shaped,
points into said recess in the direction of the stop pin 88. The
pivot axis S runs through the center of a circular inner cross
section of the pipe limb 46.
[0038] The pivoting angle which is limited by the interaction of
the stops 90 with the stop pin 88 is chosen such that there is no
contact between side faces of the angled pipe element 48 which face
the base body 18 of the fitting and the base body 18 of the
fitting, even at a maximum pivoting angle. As a result, forces
which act on the base body 18 of the fitting and the angled pipe
element 48 tangentially with respect to the pivot axis S are
prevented and deformations or leakage points which correspondingly
may be produced are avoided.
[0039] FIG. 4 shows a further embodiment of an inventive sanitary
fitting which is designed to be fitted to a wall. In this case, a
wall connection 92 for passing the water inflow 10 through a wall,
a securing nut 94 for securing the base body 18 of the fitting to
the water inflow 10, and the nozzle 82 are not shown in
section.
[0040] In contrast to the inventive sanitary fitting for platform
installation which is shown in FIGS. 1-3, the water inflow 10 here
is oriented virtually perpendicularly to the pivot axis S. For this
reason, the base body 18 of the fitting is correspondingly angled
and both the inflow-end through-passage 16 as well as the seat 28
and the longitudinal axis of the control cartridge 20 are arranged
virtually perpendicularly with respect to the pivot axis S.
[0041] Like the inflow-end through-passage 46 of the base body 18
of the fitting, which at the same time forms a housing for the
sanitary fitting, the outflow-end through-passage 30 is also
spatially widened and conducts mixed water MW from a flow direction
at the output end of the control cartridge 20, which is
correspondingly also oriented virtually perpendicularly to the
pivot axis S, to a flow direction parallel to the pivot axis S.
[0042] The bearing recess 44 is formed at the angled pipe
element-end of the outflow-end through-passage 30 of the base body
18 of the fitting. The inflow-end end region of the inflow-end pipe
limb 46 engages into the bearing recess 44 such that it can rotate.
In turn, only one single dynamic sealing element in the form of the
sealing ring 49 acts in the bearing recess 44 between the
inflow-end end region of the inflow-end pipe limb 46 and the base
body 18 of the fitting.
[0043] In contrast to the embodiment shown in FIGS. 1-3, the
bearing recess 44 in the embodiment in FIG. 4 is extended at the
angled pipe element-end in the direction of the pivot axis S in
such a way that the base body 18 of the fitting surrounds the
angled pipe element 48 in the manner of sleeve as far as the end
region opposite the bearing recess 44. A corresponding recess is
formed in the sleeve-like end region of the base body 18 of the
fitting only to enable the connection pipe 56 associated with the
water outlet 42 to pivot freely. Here, the outflow-end pipe limb 54
of the angled pipe element 48 is oriented inward toward the pivot
axis S and perpendicularly to the inflow-end pipe limb 46.
[0044] In this embodiment, the outer sleeve 36 of the fitting is of
cup-like design and has a base 96 on which a side face 98 of the
outflow-end pipe limb 54 comes to rest, said side face being
oriented perpendicularly to the pivot axis S. The outer sleeve 36
of the fitting is mounted by means of sliding rings 38 between the
outer sleeve 36 of the fitting and the sleeve-like end region of
the base body 18 of the fitting such that it can pivot.
[0045] In this embodiment, a stop screw 99 is screwed into the
outer sleeve 36 of the fitting and extends into a sleeve groove 100
which is formed on the sleeve-like end region of the base body 18
of the fitting. When the stop screw 99 strikes the stop faces of
the sleeve groove 100, circumferentially opposite stop faces (not
shown in FIG. 4) of the sleeve groove 100 limit the pivoting
angle.
[0046] In this design too, the outlet connection piece 40 which
points perpendicularly away from the pivot axis S is integrally
formed on the outer sleeve 36 of the fitting. The connection pipe
56 is guided in the outlet connection piece 40 again by means of a
guide ring 62 (not shown in FIG. 4), inserted in a sealed manner
into the outflow-end pipe limb 54 at the upstream end, and held in
a sealed manner by the pipe extension 68 of the outlet end piece 66
in its downstream end region.
[0047] The outlet end piece 66 is identical to the design shown in
FIG. 1 and, in this case too, is mounted in the outlet connection
piece 40 such that it can rotate about the axis of rotation D,
predefined by the longitudinal axis of the outlet connection piece
40.
[0048] In the described embodiments, it is of course alternatively
possible to also mount the outlet end piece 66 on the outlet
connection piece 40 such that it is fixed in terms of rotation. It
is likewise of course also possible for the longitudinal axes of
the outlet end piece 66 and the outlet connection piece 40 to be
oriented at a predetermined angle with respect to one another.
[0049] Similarly, the window 86 may be formed in a different manner
as an alternative, and the legionella filter 84 may be replaced by
another type of filter. Furthermore, it is also feasible to equip
the outlet end piece 66 with projecting handle elements which make
it easier for the user to rotate the outlet end piece 66.
