Description
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention is directed to a storage device and
system for an extractable hose, in particular for a hose being used
in an air vehicle. The invention is further directed to a method
for designing and manufacturing of a storage device as well as to a
hose storage assembly.
Discussion of Related Art
[0002] Hand-held extendable water faucets and hand-held shower
heads are used among others in the sanitary area for e.g. sinks,
showers, bidets and water-closets. In most applications, they
comprise an extendable spout with a handpiece, such as a shower
head or bidet spray, that is placed in a holder while not being
used and is removed from there while pulling a water hose connected
to the handpiece for a more comfortable utilization in a certain
distance from the holder. In order to allow such manipulation of
the hose, several approaches are known for domestic use.
[0003] U.S. Pat. No. 7,162,782 was published on 16 Jan. 2007 on
behalf of the Masco of Indiana Corp. and discloses a pull-back
mechanism of a hand sprayer unit using a coil which is received
over the water tube. When a user extends the hand sprayer by
pulling it upward, the retraction coil is compressed, after the
user releases hand sprayer the retraction coil than expands and
retracts the hand sprayer to its original position. However, the
structure of the hose leads to a large tube diameter and hence a
space consuming design. Furthermore, the hose can be tangled in the
installation/storage space with other items and as a result block
the mechanism and induce strong bending. Consequently, the hose may
be damaged causing leakage of the liquid in the hose.
[0004] WO15177664 A1 was published on 26 Nov. 2015 on behalf of
Paolo de Nora and discloses an extensible hose, comprising an inner
tubular element for being passed through by a fluid and suitable
for lengthening and widening under the action of the pressure of
the fluid. According to WO15177664A1, the extensible hose also
comprises at least one extensible outer tubular element overlying
the inner tubular element and comprising at least one surface
portion made from a second material resistant to external stresses.
One purpose of this invention is to provide an extensible hose
characterised by elastic properties, and thus elongation. Even
though such a hose is extensible, no solution is given to prevent
extreme bending of the hose that may cause damage of the hose. Such
bending may e.g. occur if the nose has to be stored in a specified
limited space when not being used.
[0005] WO15104067 A1 which was published on 16 Jul. 2015 on behalf
of DS Produkte GmbH relates to a hose with a flexible outer sheath
that allows elongation or bending of the hose up to certain degree
which can be realized by some kind of accordion hose structure. An
elastic band is placed in the inner part of the hose, which
provides a restoring force, to bring back the hose in the original
position after being pulled out. Such a system is relatively
complicated and restricted to a special type of hose.
[0006] US 2004177880 was published on 16 Sep. 2004 on behalf of the
Masco of Indiana Corp. and shows a faucet assembly which comprises
a faucet hub, a hose and a hose retraction mechanism, whereby the
faucet hub features at least one hose guide that is used to reduce
the amount of wear on the hose. The retraction mechanism allows the
hose to extend from the faucet hub. Once in the extended position,
the retraction mechanism is configured to lock the hose in the
extended position. Upon actuation by the user, the retraction
mechanism can retract the hose back inside the faucet hub. An
additional stowage bag for the hose is hanged underneath the
retraction mechanism. However, due to this setup the overall
assembly does not provide flexibility in terms of where the
assembly can be placed since it needs a lot of installation space
in vertical direction underneath the faucet. Furthermore, even
though the bag is adaptable in shape, the bag can still be
compressed and hence disturb the hose retraction or extension
process.
SUMMARY OF THE INVENTION
[0007] Whereas the systems described above may be suited for
domestic use, very specific problems emerge if used in certain
types of vehicles where space for storage of a hose oftentimes is
highly constricted and does not have the spatial dimensions that
would be needed in order to ensure proper functioning of a
retraction mechanism. Such vehicles include air vehicles (such as
e.g. airplanes or helicopters), road vehicles, (such as e.g.
recreational vehicles), railway vehicles and watercraft (e.g.
yachts).
[0008] This in particular holds true for flush toilets and sinks
where the bowl typically has a relatively large diameter and the
related handpiece (hand-held device) is conventionally arranged
laterally close-by due to ergonomic reasons. Such an arrangement
typically causes a narrow free space where a hose providing the
handpiece with liquid has to be arranged when stored. Inserting the
hose in such a spatially limited space by means of gravity only may
cause certain problems as the hose may touch obstacles inside of
the storage space and consequently will not be fully retracted into
the storage space by gravity. Often the residual portion of the
hose has to be pushed manually in the storage space by applying
force, which may cause damage to the tube due to buckling or
bending below a critical minimum bending radius.
[0009] In addition, vehicles, in particular aircraft, are usually
prone to abrupt acceleration and deceleration during operation,
which may not only impede retraction of the hose driven by
gravity-only, but may also affect the alignment of the hose when
being in the storage space. This may lead to undesired knocking
noise. As well the hose may become tangled with obstacles (e.g.
electrical, mechanical or plumbing modules) arranged in the storage
space such that the hose becomes trapped in the storage space. Even
worse, such tangling may cause kinks to develop in the hose, which
may interrupt or retard the flow within the hose or even lead to
failure of the hose. In contrast to domestic use, leakage of water
in aircraft may not only cause significant damage to the
installation space but may also critically interfere with vehicle
safety. This in particular holds true if the storage space for the
hose is not easily accessible for inspection. A storage device as
described herein after is suitable to overcome the above mentioned
problems.
[0010] A storage device, respectively a system for an extractable
hose (hose), according to the invention is normally suitable to be
arranged in or incorporating at least one narrow installation space
influenced by at least one module arranged inside or extending into
the installation space. The available installation space may at
least partially be defined by structural parts of the aircraft. In
the case of an airplane this would be at least one element out of
the following list of elements: sidewall, ceiling, stowage bin,
partition wall, fuselage skin, strut, stringer, floor, frame,
etc.
[0011] The storage device preferably comprises a first housing
member defining a first storage compartment, wherein the first
storage compartment is configured to receive at least part of the
hose. The hose can be extracted from and inserted into the first
storage compartment manually and/or automatically via a hose port
arranged at the first housing member. In a preferred embodiment the
hose port comprises a noise reducing element. In a variation, one
or several deflection pulleys are arranged closed to the hose port
and by which the hose can be extracted and inserted. The first
housing member comprises at least one spatial curved wall section
adopted to, respectively eluding, the contour of at least one
module arranged inside or extending into the installation space.
The geometry of the first housing member can be defined by an
overlay of at least two installation space. For example, in the
case of several airplanes having a similar fuselage but different
configurations of sanitary installations the common available
installation space can be defined by an overlay of the respective
configurations.
[0012] In a preferred embodiment the first storage compartment in
the first housing member has a variable cross-section along the
length of the hose. The first storage compartment may comprise a
protuberance having a larger cross-section then the hose port. The
protuberance can be foreseen to receive and store part of the hose
and/or to act as a reservoir for liquid, especially leaked liquid.
Good results are achieved if the protuberance is arranged close to
the lowest point of the first housing member. If appropriate, the
first housing member may comprise a fluid outlet to drain leaked
fluid. Alternatively or in addition, a liquid sensor can be
foreseen to indicate leaked fluid. Very good results can be
achieved if the first housing member is at least partially made by
an additive manufacturing process, e.g. 3D-printing and/or
lamination of fiber reinforced plastic material (composite
material). Thereby the housing can be adopted to special
configurations of modules extending into the installation space. At
least part of the inside of the first housing member may be coated
by a friction reducing means. The friction reducing means can be a
coating applied directly to the related surface of the first
housing member. Alternatively or in addition, the friction reducing
means can be a pad made from or comprising a friction reducing
material such as Teflon.RTM.. The first storage compartment may be
designed such that the portion of the hose when being inserted in
the first storage compartment is brought to a predefined shape by
means of gravity and/or a spring loaded retraction mechanism.
[0013] Depending on the field of application and the available
installation space, the storage device may comprise a second
housing member comprising a second storage compartment and being
interconnected with the first housing member such that the first
and the second storage compartment form a continuous compartment
for receiving at least a portion of the hose. The first and the
second housing member may be interconnected with each other in a
separable manner. Good results can be achieved when the second
housing member is at least partially made by an injection molding
process. In a preferred embodiment, the storage device comprises a
retraction mechanism for the hose which is suitable to pull the
hose actively into the storage device. The retraction mechanism may
be designed as an active retraction mechanism which excerpts a
constantly and/or temporarily force onto the hose. In a preferred
embodiment the retraction mechanism is at least partially arranged
in the second housing member. The first and/or the second housing
member may comprise at least one connecting point to connect an
auxiliary device, such as e.g. a mixing or a control unit, etc., to
the storage device. The storage device may comprise multiple
connecting points arranged in a regular pattern suitable to connect
to at least one auxiliary device.
[0014] The first housing member and/or the second housing member
can at least partially be made from a plastic material, in
particular from a polyetherimide (PEI) and/or a polyamide (PA). For
weight saving reason the first housing member and/or the second
housing member can least partially be made from a fiber reinforce
plastic material.
[0015] A method for producing a storage device for an extractable
hose arranged in an installation space preferably comprises the
following methods steps. Providing an installations space with at
least one module extending into the installation space. Adopting a
spatial curved wall section of a first housing member of a first
storage compartment of the storage device to a contour of at least
one module extending into the installation space. Producing of the
first housing member by an additive manufacturing method. Arranging
the first housing member in the installation space such that it
eludes the at least one module. Good results are achieved if the
first housing member is produced using an additive manufacturing
method, such as 3D printing, such as a fused deposition modeling
process (FDM) and/or a light polymerization process and/or a powder
bed process. At least the first housing member is normally made
from a fire retardant material.
[0016] In contrast to the systems known, the storage device
according to the invention ensures long-term reliable functioning
of a retraction mechanism for a hose even when used in vehicles
that are subject to abrupt acceleration and deceleration in various
directions. Thanks to such an active retraction mechanism friction
between the hose and the first and/or the second housing
compartment can be accounted for, leading to increased operator
convenience.
[0017] Good results may be obtained if the first storage
compartment is formed such that it fits into different installation
spaces defined by different arrangements of at least one module
extending into said installation space. This can be achieved in
that the different configurations are virtually superimposed in a
CAD-Software in the memory of a computer. 3D-printing can be used
as an additive manufacturing method and/or grinding can be used to
manufacture a positive or a negative of the first housing member
encompassing the first storage compartment. If a negative is made
from the first housing member, a positive can be made by laminating
of fiber reinforced material into and/or onto the negative.
Thereafter the negative can be at least partially removed if
required. Alternatively or in addition, the negative can form part
of the first housing member. This allows to adapt the first housing
member, respectively the stowage compartment to the space/geometry
available as well as to optimize the shape to allow proper/smooth
functioning of the stowage mechanism and prevent critical bending
radii of the tube.
[0018] As described in at least variation hereinafter the spring
mechanism can be designed such that it retracts the tube and if not
sufficient (varying tube length), the residual tube can fall freely
in the defined first housing member.
[0019] Good results may be obtained if the storage device comprises
a positioning or locking system in order to help positioning and/or
locking a handpiece connected to the hose at least temporarily when
not being used. The locking system may e.g. use magnetic force in
order to position and/or lock the handpiece in a holder. It may
also comprise an induction mechanism, e.g. an inductive coil, in
order to heat and/or dry the handpiece.
[0020] In order to detect leakage and/or induce a draining process,
a liquid sensor may be arranged within the first and/or the second
storage compartment and/or at a fluid line interconnected with the
first and/or the second storage compartment. Thus, leakage can be
detected and water supply could be cut and/or a draining process
could be initiated. Particularly reliable detection of leakage can
be obtained if the housing of the storage device is formed such
that leaked liquid collects at one or multiple predefined location
of the first and/or the second storage compartment and one or
multiple liquid sensors are arranged at this location (respectively
these locations). In order the improve operator convenience the
retraction mechanism may be electrically driven.
[0021] In order to increase operator convenience, the storage
device may comprise a ventilation and/or a heating means in order
to maintain the tube and liquid therein at a certain temperature
and/or to dehumidify the outer surface of the tube and/or
handpiece. Therefore the air-pressure in the first and/or the
second storage compartment may be increased if compared to the
passenger compartment.
[0022] In order to minimize noise emerging from the storage device,
the first and/or the second housing member may be formed such that
their resonance frequencies, respectively the resonance frequency
of the first and/or the second storage compartment lie within a
certain range. Alternatively or in addition, sound- and/or
vibration-damping material may be arranged at the first and/or
second housing member. A storage device according to the present
invention may also be used for a beverage dispensing device.

DETAILED DESCRIPTION OF THE INVENTION
[0038] The foregoing summary, as well as the following detailed
description of the preferred embodiments, is better understood when
read in conjunction with the appended drawings. For the purposes of
illustrating the invention, an embodiment that is presently
preferred, in which like numerals represent similar parts
throughout the several views of the drawings, it being understood,
however, that the invention is not limited to the specific methods
and instrumentalities disclosed.
[0039] FIG. 1 to FIG. 4 schematically show a first embodiment of a
sanitary module 10 with a storage device 60 according to the
invention. As mentioned, the invention is not limited to being used
for sanitary applications only. As shown in FIG. 1, the sanitary
module 10 shown comprises a bowl 12 of a flush toilet, a hand-held
handpiece 33 that serves as a bidet spray, respectively source of
water, and an auxiliary stowage 13 in order to e.g. stow bathroom
tissues or other goods. As indicated in FIG. 2, the sanitary module
10 comprises an installation space 11 which in a vehicle will be
typically restricted in outer spatial dimensions by encompassing
structural parts 17.
[0040] In the shown embodiment, beside the bowl 12 and the
auxiliary stowage 13 which both reach (as modules) into and thereby
take influence on the installation space 11, the installation space
11 in addition can be delimited by different configurations of
multiple modules 14 that typically fill a significant portion of
the installation space 11, as e.g. shown in FIG. 2 and FIG. 3.
[0041] In the embodiment as shown in FIG. 2 and FIG. 3 a storage
device 60 is arranged adjacent to a front wall 16 of the sanitary
module 10, mechanically interconnected to the sanitary module 10 by
fastening means 67. One advantage of the invention is that at least
the first housing member 61 can be flexibly adopted to the
available installation space 11 and the therein arranged other
modules, while the other parts of the storage device can remain
standardized.
[0042] As shown e.g. in FIG. 3 and FIG. 4, the hose storage device
60 comprises a first housing member 62 that encloses a first
storage compartment 63 which is configured to receive a portion of
the hose 30 via hose port 64 arranged in the first housing member
62. The first storage compartment 63 is formed such that the
portion of the hose 30 when being arranged in the first storage
compartment 63 takes a shape that is at least partially defined by
the shape of the first storage compartment 63, as illustrated e.g.
in FIG. 4.
[0043] The first housing member 62 is shaped such that it fits in
the free installation volume of the installation space 11 while
ensuring that a portion of a hose 30 arranged in the first
compartment 63 is not bent below a structurally critical minimum
bending radius r of it. Therefore the storage device 60 for the
extractable hose 30 is arranged in the installation space 11. The
storage device 60 comprises the first housing member 62 defining on
the inside a first storage compartment 63. As mentioned above the
first storage compartment 63 is configured to house at least a
portion of the hose 30 which extends from the first storage
compartment 63 via the hose port 64 arranged at one end of the
first housing member 62. The first housing member 62 has at least
one spatial curved wall section 69 adopted to the contour of at
least one module 14 extending into the installation space 11.
[0044] FIG. 5 shows the storage device 60 as shown in FIGS. 1-4 in
a front view. FIG. 6 is showing the storage device 60 in a
separated manner. FIGS. 7-8 are showing the inside of the storage
device 60. The storage device 60 comprises a housing 61 with a
first housing member 62 encompassing a first storage compartment 63
and a second housing member 65 encompassing a second storage
compartment 66 for storing a hose 30 on the inside. The hose 30 can
be extracted from and inserted into the storage device 60 via a
hose port 64 against a force of a retraction mechanism 70 arranged
in the second housing member 65 and as e.g. visible in FIGS.
7-8.
[0045] In the shown variation, the retraction mechanism 70
comprises a rotatable mounted deflection roller 70 which is
arranged linear displaceable in a transversal direction (arrow 76)
against the force of a spring member 72. The spring member 72, e.g.
in the form of a coil spring or a rubber band having a certain
length, extends along an upper edge 73 of the second housing member
65 parallel to the hose 30. The spring member 72 is deflected by at
least one guide roller 75. One advantage of the shown retraction
mechanism 70 is that it is comparatively flat and compact, and
therefore easy to install in narrow spaces.
[0046] Depending on the installation space, as shown hereinafter,
other kinds of retraction mechanisms can be foreseen if
appropriate. A rear end of the flexible hose 30 is interconnected
to an inlet 74. The hose 30 is deflected by the deflection roller
71 and then continues into the first storage compartment of the
first housing member 62. While the second housing member 65
comprising the retraction mechanism 70 preferably are standardized
parts, the first housing member 62 is an individually adopted
element which is designed according installation space available.
Good results are achieved if the first housing member 62 is at
least partially made by an additive manufacturing process, such as
e.g. 3D-printing. The first housing member 62 comprises a
protuberance 59 forming the lowest point of the housing 61. In the
shown variation as visible in FIG. 7 the protuberance 59 is
designed to receive a part of the hose 30 when the shower hear 33
is arranged in the hose port 64. Furthermore the protuberance 59 is
suitable to collect leaked liquid which e.g. flows back along the
hose. It can be interconnected to a drainage 81. Alternatively or
in addition a liquid sensor (humidity sensor) can be foreseen to
indicate presence of liquid in the protuberance 59.
[0047] As e.g. visible in FIGS. 5-6 the first and the second
housing member 62, 65 are designed as separate parts which are
interconnected to each other by a first and a second flange 77,
78.
[0048] A storage device 60 for an extractable hose 30 is arranged
in an installation space 11. The storage device 60 comprises a
first housing member 62 comprising on the inside a first storage
compartment 63, which is configured to house at least a portion of
the hose 30 which is extractable from the first storage compartment
via a hose port 64 arranged at the first housing member 62. The
first housing member 62 has at least one spatial curved wall
section 69 specifically adopted to an contour of at least one
module 14 extending into the installation space 11 which normally
prevents the installation of standardized parts. In case of several
relatively similar arrangements, the available installation space
11 can defined by an overlay of at least two configurations of
modules 14 extending into the installation space 11. The first
storage compartment 63 in the first housing member 62 may have a
variable cross-section along the length of the hose 30.
Alternatively or in addition, the first storage compartment 63 in
the first housing member 62 may have a protuberance 59 suitable to
receive part of the hose 30. As e.g. visible in FIGS. 5-6 the
protuberance preferably forms the lowest point of the first housing
member 62 such that e.g. leaking fluid can be collected therein. If
appropriate the first housing member 62 may comprise a fluid outlet
81 and/or a liquid sensor 82. In a preferred variation, the first
housing member 62 is at least partially made by an additive
manufacturing process, e.g. 3D printing and/or lamination of a
composite material. Alternatively or in addition, the first housing
member 62, at least during installation in the installation, space
11 can have an adjustable design. However, it is preferable that
the first housing member 62 does not deform in a negative manner,
when the hose 30 is extracted from it. The first housing member 62
may in the longitudinal direction of the hose 30 comprise several
segments which during installation are adjustable relative to each
other, e.g. the adjustable segments are pivot connected to each
other. The first storage compartment 63 is formed such that a
portion of the hose 30 when being inserted in the first storage
compartment 63 is brought to a predefined shape by means of
gravity. To reduce friction, especially in narrow and bend areas,
the first housing member 62 can at least partially be coated by a
friction reducing means, such as pads made from or coated with e.g.
Teflon.RTM. or a similar material.
[0049] In the variations as shown in FIGS. 1-8 the storage device
60 comprises a second housing member 65 comprising a second storage
compartment 66 and being interconnected with the first housing
member 62 such that the first and the second storage compartment
63, 66 form a continuous compartment for receiving at least a
portion of the hose 30. The first and the second housing member 62,
65 are interconnected with each other in a separable manner by a
first and a second flange 77, 78. The storage device 60 comprises a
retraction mechanism 70 for the hose 30, which is arranged in the
second housing member 65. The first housing member 62 at least
partially transfers the force necessary to extract the hose 30 from
the hose port 64 between the hose port 64 and the retraction
mechanism 70 interconnected to the second housing member 65. The
first and/or the second housing member 62, 65 may comprise at least
one connecting point 68 to connect an auxiliary device, such as a
mixture valve 50 to the storage device 60. The storage device 60
may comprise multiple connecting points 68 arranged in a regular
pattern. Good results can be achieved when the first housing member
62 and/or the second housing member 65 are at least partially made
from a plastic material, in particular from a polyetherimide PEI
and/or a polyamide PA or from a ceramic material or from a
metal.
[0050] FIGS. 10-12 and FIGS. 13-14 show a second and a third
variation of a sanitary module 10 in a simplified manner. Both
modules comprise an installation space 11 into which modules 14 are
arranged or reach into, e.g. such as a bowl 12. In the variation
according to FIGS. 10-12 the first housing member 62 has a tubular
shape encompassing a first storage compartment 63 having an in
principal constant diameter along the general extension of the hose
30. The wall of the first housing member 62 is spatially curved
around the bowl 12 which extends into the installation space 11. In
this variation the hose 30 is itself comprises a helical spring
section and is thereby elastically expandable from the hose port
64. The hose 30 incorporates thereby the retraction mechanism 70.
The outer diameter of the helical shaped hose 30 is smaller than
the inside diameter of the tubular first housing member 62. FIG. 11
shows the hose in the contracted position completely arranged
inside the first storage compartment. FIG. 12 shows the hose 30
partially extended through the hose port 64. One advantage of the
shown variation is the simple, robust and compact design. The
design of the first housing member 62 can easily be adopted to the
specific installation space 11 available in the sanitary module 10.
If appropriate, the first housing member can be equipped by a
drainage which is preferably arranged at the lowest position of the
first housing member. FIGS. 13-14 show a third variation of a
storage device 60. The storage device 60 comprises an extractable
hose 30 and is arranged in a narrow installation space 11. The
storage device 60 comprises a first housing member 62 defining a
first storage compartment 63. The first storage compartment 63 is
configured to house at least a portion of the hose 30 which is
extractable from the first storage compartment 63 via a hose port
64 arranged at one end of the first housing member 62. The outer
wall of the first housing member 62 is spatial curved eluding the
contour of the bowl 12 which extending into the installation space
11. The first housing member 62 can at least during installation in
the installation space 11 have an adjustable design, e.g. by being
bendable. The first housing member 62 can in longitudinal direction
of the hose 30 comprise several segments (not shown in detail)
which during installation are adjustable relative to each avoiding
obstacles. Good results can be achieved when the adjustable
segments may be pivot connected to each other. The storage device
60 comprises a second housing member 65 which is interconnected to
the first housing. It a second storage compartment 66. The first
and the second storage compartment 63, 66 form a continuous
compartment for receiving at least a portion of the hose 30.
