Description
Water reservoir container for a vehicle
The invention relates to a water reservoir container for
mounting in the roof region of a vehicle, in particular rail
vehicle, said water reservoir container generally being of
cylindrically symmetrical form.
Such a water reservoir container is used in vehicles of all
types, such as trains, aircraft and ships, and is part of a
water supply system for the respective vehicle. Various
consumers which are present on the vehicle are supplied with
water from the water reservoir container. Such consumers are,
for example, a WC, a hand wash basin, a food preparation
facility, a dishwasher, etc, the delivery of water taking place
in each case via suitable pipelines.
In light of the limited capacity of a water reservoir
container, this regularly has to be filled up with water so as
to be constantly available to the connected consumers.
Water reservoir containers used hitherto in vehicles are of
cylindrically symmetrical form and have a rectangular base. The
result of this is that, for new projects, the design of water
containers has to be adapted to these in each case. Examples of
vehicles equipped in this way are: ICE T, ICE 3, Velaro E,
Velaro RUS and Velaro CRH3.
Preceding from this, the object on which the invention is based
is to specify a water reservoir container for mounting in the
roof region of a vehicle, which water reservoir container can
be used in many different vehicles at low outlay in terms of
adaptation.

In the water reservoir container initially mentioned, this
object is achieved in that it has an at least partially curved
circumferential face and two end faces adapted to the
dimensions of the circumferential face, at least two mutually
opposite fastening brackets for mounting the water reservoir
container in the roof region of the vehicle being attached to a
circumferential face of the water reservoir container.
The at least partially curved circumferential face has the
effect that, for example in curved high roofs in the rail
vehicle sector, the water reservoir container can beneficially
utilize the space available in the roof region. This is the
case particularly when the curved part of the circumferential
face is adapted to a curvature of the roof in the installation
region.
The at least two fastening brackets provided enable the water
reservoir container to be used in various forms of vehicle. In
at least the predominant number of cases, it will be possible
to carry out on the vehicle side adaptations such that mounting
with the aid of the fastening brackets is possible. The
fastening brackets may otherwise even be modified, if required.
To utilize the space available in the roof region of a vehicle,
it may be beneficial if the base of the water reservoir
container is of essentially elliptic form. In this case, the
water reservoir container will be arranged in the roof region
in such a way that its largest diameter is arranged essentially
horizontally with respect to the vehicle. The circumferential
face of the water reservoir container can thereby be adapted
beneficially to the shape of the roof, for example in so far as
the vehicle is a version with a high roof.

The water reservoir container may have a peripheral margin for
support in the roof region of the vehicle. This refers
particularly to the use of the water reservoir container on
flat roofs. In so far as these are provided with a suitably
dimensioned pressed cutout, the water reservoir container can
be embedded into this cutout and is supported on the roof of
the vehicle. Fastening of the water reservoir container
additionally takes place with the aid of the fastening
brackets.
Advantageously, the water reservoir container is designed to be
self-supporting. This means that, for mounting purposes, any
material reinforcements on the water reservoir container may be
dispensed with. Its mounting in the roof region of the vehicle
can be carried out solely with the aid of the fastening
brackets.
Exemplary embodiments of the invention are explained in more
detail below with reference to the drawings in which:
figure 1 shows a cross-sectional view of a roof region of
a rail vehicle with an installed water reservoir
container in a high-roof version,
figure 2 shows a perspective view of a water reservoir
container for installation in a rail vehicle in
a flat-roof version, and
figure 3 shows a perspective view of a further embodiment
of a water reservoir container for installation
in a rail vehicle in a high-roof version.
The water reservoir containers 1, 2, 3 illustrated in figures 1
to 3 have in common in each case the fact that they are
cylindrically symmetrical and have an essentially elliptic
base. The water reservoir containers

1, 2, 3 are in each case end faces S which are adapted in each
case to the dimensions of the water reservoir container 1, 2, 3
in its inner region.
Figure 1 shows the water reservoir container 1 in the installed
state, specifically in the roof region of a rail vehicle in a
high-roof version. It can be seen that a circumferential face U
of the water reservoir container 1 is curved at least in its
region facing the roof 4. This curvature is selected such that
the construction space inside the roof 4 can be utilized as
efficiently as possible. At the same time, care must be taken
to ensure that the form of construction of the water reservoir
container 1, 2, 3 is such that a self-supporting structure is
obtained. This ensures that the water reservoir container 1, 2,
3 can be used not only on a special type of vehicle, but, for
example, throughout an entire fleet or else in different
vehicle series, with only insignificant adaptation work needed.
This adaptation work refers primarily to enabling the water
reservoir container 1, 2, 3 to be mounted in the roof region of
a respective rail vehicle. For this purpose, fastening brackets
5, 6, 7 are provided which are arranged horizontally and
opposite one another on the respective water reservoir
container I, 2, 3 and are in each case welded to a basic body
of the water reservoir container 1, 2, 3 from outside. The
fastening brackets lie in the region of the largest diameter of
the water reservoir container 1, 2, 3.
It should be emphasized that figure I shows the water reservoir
container I for a high-roof version of a rail vehicle, the
water reservoir container 1 being arranged between the roof 4
and an internal ceiling 8. The fastening brackets 4 are in this
case supported on longitudinal roof beams 9 of the rail
vehicle, these being the sole supports for the water reservoir
container I.

Figure 2 shows the water reservoir container 2 for use on a
rail vehicle in a flat-roof version. Here, as compared with the
embodiments according to figures 1 and 3, an additional
peripheral margin 10 is provided. The water reservoir container
2 is inserted into a correspondingly dimensioned cutout in the
flat roof of the rail vehicle, the margin 10 then being
supported on the respective roof portion.
The water reservoir containers 1 and 2 are designed in each
case for a two-day filling cycle, the water reservoir container
3 according to figure 3 being intended for a one-day filling
Cycle. To that extent, the water reservoir containers 1, 2, on
the one hand, and the water reservoir container 3, on the other
hand, differ from one another in their holding capacity for
fresh water.
