Assembly for Bridging a Gap in the Lower Area of a Door field of Railway
Vehicles
The invention relates to an assembly for bridging a gap in the lower area of a
door field
of railway vehicles between the entry/exit and a railway platform, which is
arranged on the
railcar body in the door field of railway vehicles in the form of a height-
adjustable bumper strip.
As a result, the manufacturing tolerances of the entry/exit edge of the
railcar body shell and the
bogie can be compensated.
From the prior art, edge elements for railway platforms for trains are known,
wherein the
railway platform extends at a certain height relative to the rails, so that
the level of the railway
platform corresponds to the entrance height of a train standing on the rails.
Such edge elements
are in DE 602004009856 T2 and in EP 1431154 A 1. The disadvantage here is that
all railway
platforms have to be provided with such edge elements over the entire possible
train length, and
the edge elements are not matched to the different exit heights due to the
different railway
vehicle construction types, to the floating connection between the bogies and
the railcar bodies
of the vehicle and to manufacturing tolerances.
Moreover, arrangements for bridging a gap have already been disclosed, which
are
arranged on the railcar body structure in the area of the door opening of a
railway vehicle. These
are characterized either by an expensive, motor-driven construction or they
are in a static
stationary arrangement that is not adjustable in terms of height on the
railcar body structure of
the railway vehicle. Such arrangements are described, for example, in the
published documents
FR 2887838 (A1), US 7,178,467 B2, DE 202009006413 Ul and EP 2489568 A2.
The problem of the present invention consists in providing a simple
construction for an
arrangement for bridging a gap in the lower area of a door field of railway
vehicles between the
1

r
CA 02896912 2015-06-30
entry/exit and a railway platform, which is suitable for setting different
height distances between
the railway platform and the exit.
According to the invention, this problem is solved by the features of Claim 1.
Advantageous embodiments of the invention are presented in the dependent
claims.
Accordingly, the invention comprises an assembly for bridging a gap in the
lower area of
the door field of a railway vehicle, wherein the latter comprises a bracket
which is screwed to the
railcar body of the railway vehicle in the lower area of the door field. The
bracket here is in an
active connection with at least one support via a screw connection, wherein,
on the support, a
bumper strip is arranged on the side facing away from the railcar body. The
support here can
form a single piece over the length of the bracket or it can be screwed at
several sites next to one
another to the bracket.
According to a particular feature of the invention, on the screw-connection
surface facing
the railcar body, the bracket comprises several elongated holes spaced apart
from one another,
which are provided for the connection with the railcar body. As a result, a
purely vertical setting
and an adaptation of the arrangement to possible manufacturing tolerances of
the railcar bodies
in the vertical direction of the railway vehicle are achieved. Moreover, the
bracket presents
several lateral connection ridges angled to the side vertically by 900 with
openings or bores,
wherein between a plurality of these ridges, horizontally angled guide ridges
are provided.
The support comprises several connection ridges angled to the side vertically
by 90 with
elongated holes, wherein horizontally angled support ridges are provided
between a plurality of
these connection ridges, wherein the support ridges have lugs. Here, the screw
connections are
advantageously arranged between the openings of the connection ridges and the
elongated holes
2

CA 02896912 2015-06-30
of the connection ridges, wherein the arrangement is height-adjustable via the
screw connection.
Here, the guide ridges are guided and held between the lugs of the support
ridges.
According to another feature of the present invention, it is provided that the
bumper strip
consists of a rubber element that is applied by vulcanization on the support.
Advantageously,
damage to the arrangement due to possible contact with the railway platform
can thus be
prevented.
There are numerous design possibilities for the arrangement according to the
invention.
Here, on one hand, reference is made to the claims following Claim 1, and, on
the other hand, to
the description of embodiment examples in reference to the drawing. The
drawings show:

and
Figures 6a-c different settings of the assembly relative to the railway
platform height in
a side view represented in cross section.
Figures la-c and Figures 2a-c show the details of the bracket 1.1 and of the
support 1.2 in
different views. The bracket 1.1 has several elongated holes 1.1.1 spaced
apart from one another
on the screw-connection surface facing the railcar body 2, and several
connection ridges 1.1.2
angled vertically by 90 with openings 1.1.3. In addition, horizontally angled
guide ridges 1.1.4
are provided between the ridges 1.1.2. The vertical elongated holes 1.1.1
allow a vertical setting
of the arrangement on the railcar body (2).
The support 1.2 comprises connection ridges 1.2.1 angled vertically by 90
with
elongated holes 1.2.2. By means of the elongated holes 1.2.2 in circular
arrangement, by rotation,
an angular adjustment of the upper surface of the bumper strip 1.4 which can
be walked on can
occur, and thus a change in the height of the entrance edge can occur. The
lugs 1.2.3.1, 1.2.3.2
are used for bracing the arrangement in the case of possible contact with a
railway platform.
Between the connection ridges 1.2.1, horizontally angled support ridges 1.2.3
are provided,
which have lugs 1.2.3.1, 1.2.3.2.
Figures 3a-c show the entire arrangement in different views in the assembly
with the
bumper strip 1.4 which is consists of a rubber element and which is applied on
the support 1.2 by
vulcanization. The bumper strip 1.4 with the rubber element is used for
bridging a gap with
respect to the railway platform. In case of any contacts, damage to the
vehicle frame is prevented
by the bumper strips 1.4. The gap between the vehicle and the railway platform
is necessary

CA 02896912 2015-06-30
because of the floating connection between the bogie of the vehicle and the
railcar body 2 of the
vehicle (vehicle dynamics). The screw connection 1.3 is arranged between the
openings 1.1.3 of
the connection ridges 1.1.2 and the elongated holes 1.2.2 of the connection
ridges 1.2.1, wherein
the arrangement 1 is height-adjustable via the screw connection. Here, the
guide ridges 1.1.4 are
guided between the lugs 1.2.3.1, 1.2.3.2 of the support ridge 1.2.3. Here, the
support 1.2 can
form a single piece over the length of the bracket 1.3 (Figures 3a-c) or it
can be screwed at
several sites next to one another to the bracket 1.3 (Figure 5).
In Figures 6a-c, three different settings of the arrangement relative to the
railway
platform height are shown in a side view represented in cross section. The
height adjustment can
here occur relative to the step angle in the door area of the railway vehicle
and relative to the
railway platform height. In sum, this arrangement allows a purely vertical
setting and also an
angular setting of the upper surface of the bumper strip which can be walked
on. The settability
here occurs as the sum of a vertical adjustability of the bracket 1.1 via the
elongated holes 1.1.1
as well as of the elongated holes 1.2.2 arranged in a circle of the support
1.2. Due to the
adjustability, the entrance edge always remains at the same height.
