Connection for floor covering in vehicles, in particular, in rail vehicles
This invention relates to a vehicle construction with a connection for a floor
covering in
vehicles, in particular railway vehicles for the transport of passengers, with
a rigid
bottom profile plate supported on longitudinal girders, on which bottom
profile plate the
floor construction and other installation parts can be installed, whereby the
floor
covering is supported over its entire surface on the floor plates and is
elevated in a
dished shape in the attachments and installations sections that are fastened
to the
bodywork of the vehicle construction, for example to cover instrument and
equipment
cabinets and side wall panels, seat frames and partitions of the vehicle.
DE 31 15 699 C2 describes a floor of a vehicle, in particular a railway
vehicle, which has
a floor support on which fastening rails are located to anchor the
installation parts, and
floor plates are supported between the fastening rails independently of the
fastening
rails. The floor support is realized with a continuous bearing surface, and
the floor plates
are supported over the entire surface on an insulation layer that is laid on
the floor
support.
The peripheral area of the laid floor covering is realized in a dished shape.
For that
purpose, the longitudinal girders have a rounded bearing surface that runs in
the
longitudinal direction in the interior of the vehicle, which fits flush with
the cover plates of
the floor construction and forms a bearing surface that covers the entire
surface, so that
the floor covering that is laid on it is elevated on the long sides.

One disadvantage of this example of the prior art is that the floor
construction is rigidly
connected with the longitudinal girders, side walls etc. in particular by
means of the floor
covering. There is no provision for equalizing tolerances in the interior
construction of
railway vehicles.
The forces of the accessory parts are transmitted into the floor and exert a
unilateral
load on the floor.
The object of the invention is to make it possible by means of a floating
floor
construction to equalize tolerances in the interior construction in railway
vehicles and to
allow a relative movement between the installation parts such as seats, rear
walls,
equipment cabinets etc. that are firmly attached to the bodywork and the floor
to reduce
the stresses, whereby the penetration of moisture between the floor and the
attachments and installations sections that are fastened to the bodywork and
move
relative to the floor can be reliably prevented.
The invention teaches that this object is accomplished by a vehicle
construction of the
type described above and with the characterizing features disclosed in Claim
1.
Advantageous developments of the invention are described in the dependent
claims.
The vehicle construction claimed by the invention makes it possible to realize
the floor
so that it is completely free-floating. This arrangement has the advantage
that any
stresses that occur between the components as a result of the relative
movement of the
floor in the longitudinal and transverse direction can be reduced. The forces
exerted by
adjacent components, in particular seats and equipment cabinets etc., are
transmitted
into the car body independently of the floor. The horizontal tolerance
equalization is
performed by a sealing profile which slides on the attachments

and installations sections fastened to the bodywork and simultaneously
guarantees that
no moisture, such as washing water, for example, can penetrate into adjacent
assemblies or modules.
The vehicle construction with a connection for a floor covering taught by the
invention is
simple and compact. It is also easy to assemble and can thus be adapted
flexibly to a
wide variety of installation conditions.
One exemplary embodiment of the invention is explained in greater detail below
and is
illustrated in the accompanying figures, in which:
Figure 1 shows a floor connection of the prior art, and
Figure 2 is a sectional drawing of the floor connection taught by the
invention.
Figure 1 shows a floor connection of the prior art. Supported on the
longitudinal girders
1 is a bottom profile plate 2, on which a floor construction consisting of an
insulating
layer 3, cover plates 4, floor plates 5 and 6, a PVC floor covering 7 and a
floor carpet 8
are installed. In the side portion of the floor, as a transition to the side
wall 9, there is a
wooden frame 10. The longitudinal girder 1 has an inwardly directed rounded
support
surface 11 which runs flush with the floor covering 7. The floor covering 7
with the floor
carpet 8 is elevated in a dished shape and rests on the bearing surface 11.
Thus the
floor covering 7 with the floor carpet 8 has a rigid connection to the
longitudinal girder 1
and permits no displacement in the longitudinal and transverse direction.
Likewise, no
horizontal tolerance equalizations are possible.

Figure 2 shows the floor connection taught by the invention. The floor plates
5 that sit
on the floor support element 19 have, on their ends, a hollow-chamber corner
profile 12
which runs along the attachments or installed sections 18 fastened to the
bodywork,
whereby one leg 13 of the corner profile 12 is inserted into the floor plates
5 and is
fastened by bolts or rivets. The other leg 15 projects vertically with respect
to the leg 13
and with said leg 13 forms the inwardly directed rounded support surface 11
for the floor
covering 7. The dish-shaped support surface 11 ends flush with the surface of
the floor
plates 5, so that the floor covering in the longitudinal direction is laid in
an elevated
fashion along the hollow chamber corner profile 12 and can be glued to the
bearing
surface 11. On its back side, the projecting leg 15 of the hollow chamber 12
has a
groove 16 in which a flexible rubber seal 17 is inserted. The flexible rubber
seal 17
provides a seal with respect to the attachments and installations 18 that are
fastened to
the bodywork. The leg 15 of the hollow chamber corner profile 12 is therefore
movable
in the longitudinal and transverse direction, and is capable of easily
absorbing horizontal
tolerances of the body work and interior construction, because it does not
have any
fixed connection with the adjacent attachments and installation sections 18
(modules or
assemblies).
