Abstract

A paneling element for lining the inside of a side wall of a rail vehicle has a plate-shaped base body and an angled strip element which extends substantially parallel to an end side of the base body and which is embodied in one piece with the base body. The base body and the strip element form a receptacle in which a connecting element can be accommodated. The paneling element can be connected to the inside of the side wall by way of the connecting element. As a result, the paneling element can be easily and cost-effectively attached in a secure fashion to the inside of the side wall of the rail vehicle.

Description

The invention relates to a paneling element, an arrangement and a method for lining an inside of a side wall of a rail vehicle.
It is commonly known that a side wall paneling for a side wall of a rail vehicle serves to visually conceal an inside of a body shell of the rail vehicle.
From practical experience, it is known that an arrangement for lining an inside of a side wall of a rail vehicle has two plate-like paneling elements, which are arranged adjacent to each other and are fastened to the inside of the side wall by means of connecting elements.
There is a general need to fasten a paneling for a side wall of a rail vehicle in a simple and cost-effective manner securely to an inside of a side wall of the rail vehicle.
An object of the invention is to define measures whereby a paneling for a side wall of a rail vehicle can be fastened in a simple and cost-effective manner securely to an inside of a side wall of the rail vehicle.
This object is achieved by a paneling element for lining an inside of a side wall of a rail vehicle, an arrangement for lining an inside of a side wall of a rail vehicle, and a method for lining an inside of a side wall of a rail vehicle according to the independent claims.
According to the invention, a paneling element for lining an inside of a side wall of a rail vehicle is provided, comprising a plate-like main body and an angled strip element, which latter extends substantially parallel to an end face of the main body and is configured in one piece with the main body, wherein the main body and the strip element form a receptacle, in which can be accommodated a connecting element by means of which the paneling element can be connected to the inside of the side wall.
The paneling element according to the invention can be connected to the inside of the side wall of the rail vehicle in a particularly simple and secure manner, since a connecting element can be held in a receptacle running along an end face of a main body of the connecting element and, at the same time, can be connectable to the inside of the side wall of the rail vehicle.
Since the strip element and the main body can be configured in one piece, the paneling element can be produced in a particularly cost-effective manner.
Embodiments of the paneling element are described below. These also apply to the arrangement and the method.
The paneling element can be produced as a pressed part, so that the paneling element can be producible in a particularly cost-effective manner in a single work step.
In particular, the main body of the paneling element can be of cuboid configuration and a longitudinal side of the cuboid main body can extend along a longitudinal direction of the rail vehicle. The strip element can extend transversely, in particular perpendicularly, to the longitudinal extent of the main body.
In particular, the strip element can be arranged on the main body at a distance from the end face of the main body, so that the receptacle can have sufficient depth to accommodate the connecting element.
In particular, the strip element can have an elongate body having two strip portions, which can be arranged transversely, in particular perpendicularly, to each other. This can enable a cost-effective and simple production of the strip element overall.
In particular, the receptacle can be of elongate, in particular groove-shaped configuration and extend along the entire longitudinal extent of the strip element.
In particular, the main body can have notches adjacent to one or both surfaces of the strip element, which notches can enable a slight movement of the strip element in a direction transversely, in particular perpendicularly, to a longitudinal extent of the strip element. As a result, stresses which can be exerted on the strip element due to the mounting of the paneling element on the inside of the side wall or in a mounted state of the paneling element, can hence be reduced or avoided.
The end face of the main body and an end face of the strip element can be arranged adjacent to each other, viewed with respect to a direction toward an opening of the receptacle, so that the main body and the strip element can terminate flush with each other viewed in the direction toward the opening of the receptacle. A contact force which is approximately equally large on both sides can hence be applied to the connecting element, so that the connecting element can be held particularly securely in the receptacle.
In addition, a connection of the paneling element to the inside of the side wall can be realized without breaching of the strip element, so that the strip element cannot be subjected to any additional stresses and the paneling element can be securely fastenable to the inside of the side wall. In addition, in the mounted state of the paneling element, only a slight gap, through which the connecting element can be visible, can remain to an adjacently arranged paneling element.
The strip element can have one or more pocket-like bulges, which can be facing away from the main body. In particular, the plurality of pocket-like bulges can be similarly, in particular identically, configured. The receptacle which can be formed by the strip element and the main body can hence be widened in the region of the pocket-like bulge of the strip element, so that the connecting element can be introduced particularly easily into the receptacle. An assembly effort involved in connecting the paneling element to the inside of the side wall of the rail vehicle can hence be reduced.
The pocket-like bulge of the strip element, viewed along the end face of the main body of the connecting element, can be arranged on an end region of the main body or on a middle region of the main body. The paneling element can hence be connected to the inside of the side wall of the rail vehicle at a plurality of connecting points, so that an unwanted detachment of the paneling element from the inside of the side wall in the course of time can be prevented.
The invention further relates to an arrangement for lining an inside of a side wall of a rail vehicle, comprising a first paneling element (described above) for lining the inside of the side wall, a second paneling element (described above) for lining the inside of the side wall, and a connecting element, by means of which the first paneling element and the second paneling element are connectable to the inside of the side wall, wherein the connecting element is accommodated in a receptacle of the first paneling element and in a receptacle of the second paneling element, which latter receptacle lies opposite the receptacle of the first paneling element.
The arrangement according to the invention consequently enables a particularly simple lining of the inside of the side wall of the rail vehicle, since paneling elements arranged adjacent to each other can be connected by means of a common connecting element, which can simultaneously serve for the connection to the inside of the side wall. The arrangement according to the invention can therefore have few components, so that the arrangement can be produced in a particularly cost-effective manner. In addition, a mounting of the arrangement can be carried out in a particularly short time, so that assembly costs of the arrangement can be particularly low.
Embodiments of the arrangement are described below. These also apply to the paneling element and the method.
In particular, the first and second paneling element can be arranged in mirror image to each other, and openings of the receptacles of the first and second paneling element can face each other.
The arrangement further has an elongate spring element, which is accommodated, in particular press-fitted, by force closure in the receptacles of the first and second paneling element. In particular, the spring element can be configured as a metal plate. The spring element can enable a stable, flexible connection between two adjacent paneling elements, so that the stability of the arrangement can be enhanced.
A surface of the spring element, which surface can be facing away from the main body, can be covered, in particular fully, with a damping element, in particular felt.
Damage to the first and second paneling element by the connecting element can hence be avoided, since the damping element, which can be facing toward the connecting element, can cushion vibrations of the connecting element in the mounted state of the arrangement. In addition, the mounting of the arrangement can be simplified, in particular compared with an introduction of the damping element into the receptacle of the first and second paneling element and/or a bonding of the damping element in the receptacles of the first and second paneling element, since the spring element already provided with the damping element can be inserted ready-made into the receptacles of the first and second paneling element.
In particular, the damping element can be stuck onto the spring element, so that a particularly simple and therefore cost-effective production of the damped spring element can be enabled.
In particular, the connecting element can have a connecting plate and a connecting bracket, and the connecting plate and the connecting bracket can be screwed together and bolted to the inside of the side wall. Since the connecting element can be configured as a two-part component, production-related tolerances of the connecting element can be compensated by the assembly process.
In particular, the connecting plate can be of cuboid configuration.
In particular, the connecting bracket can have a U-shaped main body and two contact plates, which can respectively be arranged on end regions of a different branch portion of the main body and can extend substantially parallel to a connecting portion of the main body which can join together the branch portions. In particular, the contact plates can be arranged outside the main body and be configured, for instance, as bent-over end regions of the branch portions in one piece with the main body. The connecting portion can here be bolted to the connecting plate. This can enable a cost-effective production of the connecting bracket, which can be sufficiently stable to bear the paneling element.
In particular, a longitudinal extent of the connecting portion and of the contact plates can be transverse, in particular perpendicular, to the longitudinal extent of the strip element and/or a longitudinal extent of the receptacle.
The invention further relates to a rail vehicle, in particular a train, for instance a high speed train, which has an arrangement (described above) for lining an inside of a side wall of the rail vehicle.
The invention further relates to a method for lining an inside of a side wall of a rail vehicle, comprising the steps: provision of a first paneling element (described above) for lining the inside of the side wall, provision of a second paneling element (described above) for lining the inside of the side wall, and connection of the first paneling element and of the second paneling element to the inside of the side wall by means of a connecting element, wherein the connecting element is accommodated in a receptacle of the first paneling element and in a receptacle of the second paneling element, which latter receptacle lies opposite the receptacle of the first paneling element.
Embodiments of the method are described below. These also apply to the paneling element and the arrangement.
The method further comprises: provision of an elongate spring element and arrangement of the spring element in the receptacles of the first and second paneling element along an entire longitudinal extent of the receptacles prior to the connection of the first and second paneling element to the inside of the side wall. The first and second paneling element can hence be fastened as a preassembled module to the inside of the side wall, so that the assembly effort in the rail vehicle can be reduced.

The above-described characteristics, features and advantages of this invention, as well as the way in which these are attained, become more clearly and more plainly comprehensible within the context of the following description of the illustrative embodiments, which are explained in greater detail in connection with the drawings. The below-represented features can here represent, both respectively in isolation and in combination, an aspect of the invention, wherein:

FIG. 4 shows a schematic perspective view of the first paneling element and of the first connecting element of the arrangement in FIG. 1.

An arrangement 10, represented in FIG. 1, for lining an inside 12 of a side wall 14 of a rail vehicle configured as a train has a first paneling element 16, a second paneling element 18 and a third paneling element 20. The first and second paneling element 16, 18 are connected one to the other and to the inside 12 of the side wall 14 of the train by means of a first and second connecting element 22, 24. The second and third paneling element 18, 20 are connected one to the other and to the inside 12 of the side wall 14 of the train by means of a third and fourth connecting element 26, 28. Those components of the arrangement 10 which are shown in FIG. 1 can be arranged repeatedly, as a group, along a longitudinal extent of the train.
The first, second and third paneling element 16-20 are identically configured and have in their middle respectively a rectangular window opening, which overlaps with a window aperture of the side wall 14. Each paneling element 16-20 is produced as a pressed part. The first, second, third and fourth connecting elements 22-28 are likewise identically configured as respectively two-part components.
With reference to FIGS. 2 to 4, the first and second connecting element 16, 17 and the first connecting element 20 are described below.
The first and second paneling element 16, 18 respectively have a plate-like main body 30 a, b and an angled strip element 32 a, b, which latter extends substantially parallel to an end face 34 a, b of the main body 30 a, b and is configured in one piece with the main body 30 a, b. A longitudinal extent of the strip element 32 a, b corresponds to a width direction of the main body 30 a, b of the first and second paneling element 16, 18 which is identical to a longitudinal direction of the train.
The strip element 32 a, b is arranged on the main body 30 a, b at a distance from the end face 34 a, b of the main body 30 a, b and has an elongate body 36 a, b having two strip portions 38 a, b, 40 a, b, which are bent at a right angle to each other. The strip portion 38 a is arranged on the main body 30 a, b. The main body 30 a, b and the strip element 32 a, b form a groove-shaped receptacle 42 a, b, which extends along the entire longitudinal extent of the strip element 32 a, b and is open in the direction of an end face 34 a, b of the main body 30 a, b. The end face 34 a, b of the main body 30 a, b and an end face 44 a, b of the second strip portion 40 a, b of the strip element 32 a, b are here arranged adjacent to each other viewed with respect to a direction toward an opening of the receptacle 42 a, b, so that the end face 34 a, b of the main body 30 a, b and the end face 44 a, b of the strip element 32 a, b close off the paneling element 16, 18 roughly flush in the direction of the opening of the receptacle 42 a, b and the strip element 32 a, b does not protrude from the main body 30 a, b.
The main body 30 a, b has adjacent to both surfaces of the first strip portion 38 a, b notches 45 a-d, which enable a slight movement of the strip element 32 a, b along the longitudinal direction of the main body 30 a, b. In addition, the first strip portion 38 a, b tapers in the direction toward the second strip portion 40 a, b and a thickness of the second strip portion 40 a, b is approximately constant.
The strip element 32 a, b further has respectively two pocket-like bulges 46 a, b, which are recessed in a stepped manner in a direction facing away from the main body 30 a, b. The receptacle 42 a, b is hence widened in the region of the pocket-like bulges 46 a, b in the direction facing away from the main body 30 a, b and has corresponding widenings 50 a, b.
As shown in FIG. 3, the paneling elements 16, 18 are arranged adjacent to each other in such a way that the respective receptacles 42 a, b of the paneling elements 16, 18 lie opposite each other in a precisely fitting manner with respect to the pocket-like widenings 50 a, b of the respective receptacles 42 a, b.
The end faces 34 a, b of the main bodies 30 a, b are spaced apart by a distance S, which roughly corresponds to a width of the second strip portion 40 a, b (FIG. 2).
The arrangement 10 further has per connecting element 22-28 an elongate spring element 52, which is configured as a metal leaf spring and one surface of which is lined along an entire longitudinal extent of the spring element 52 with a damping element 54, for instance felt. The spring element 52, viewed along its width direction, is accommodated in one-third measure within the strip element 32 a, b and bears with its free side 56, i.e. with its side not lined with the damping element 54, against a surface of the main body 30 a, b. About one-third of the surface 56 of the spring element 52 is visible, along the width direction of the spring element 52, between the adjacently arranged paneling elements 16, 18.
The first connecting element 16 has a cuboid metal connecting plate 58, having a through hole 59 provided in the middle of the connecting plate 58, and a connecting bracket 60. The connecting bracket 60 has a U-shaped main body 62, which has two branch portions 64, 66 and a connecting portion 68 extending perpendicularly to the branch portions 64, 66. End regions of two contact plates 70, 72, arranged outside the main body 62, of the connecting bracket 60 are connected at an open end of the main body 62 to respectively a different branch portion 64, 66. The main body 62 and the contact plates 70, 72 are configured in one piece as bent metal plates. In the connecting portion 68, a centrally arranged through bore 74 is provided. Each contact plate 70, 72 has a through hole 76, 78.
In a mounted state of the arrangement 10, the connecting plate 58 bears against the damping element 54 and, in one-third measure, against an inside of the second strip portion 40 a, b of the strip element 32 a, b. A bolt 82 is placed through the through hole 59 of the connecting plate 58 and through the through hole 74 of the connecting portion 68 of the main body 62 and fixed by means of a nut 84. A surface of the connecting portion 68 of the main body 62 of the connecting bracket 60, which surface is facing toward the main body 30 a, b, here bears against that surface of the second strip portion 40 a, b of the strip element 32 a, b which is facing away from the main body 30 a, b. The second strip portion 40 a, b is hence clamped, by form closure and force closure, between the connecting plate 58 and the connecting portion 68 of the connecting bracket 60. As shown in FIG. 2, a further, multipart damping element 70, namely elongate foam rubber webs, can be arranged parallel to the longitudinal direction of the main body 30 a, b, between that surface of the second strip portion 40 a, b which is facing away from the main body 30 a, b and that surface of the connecting portion 68 which is facing toward the main body 30 a, b. The contact plates 70, 72 extend along the longitudinal extent of the first and second paneling element 16, 18 and here bear flush against the inside 12 of the side wall 14. Bolts, which are placed through the through holes 76, 78 of the first and second contact plate 70, 72, are bolted through the inside 12 of the side wall 14 into the side wall 14.
The arrangement 10 can have further connecting elements, which are fastened in receptacles which, viewed in the longitudinal direction of the train, are formed by a first and last paneling element. That end region of the last paneling element which is pointing in the longitudinal direction of the train and that end region of the first paneling element which is pointing counter to the longitudinal direction of the train are configured identically to the described, mutually facing end regions of the paneling elements 16, 18. The connecting elements are configured identically to the connecting elements 20-28.
In a method for lining the inside 12 of the side wall 14 of the train, the first, second and third paneling element 16-20 and the first to fourth connecting element 22-28, as well as two spring elements 52 lined with damping elements 54, are firstly provided. After this, the respective connecting plates 58 of the first and second connecting element 22, 24 are inserted one after the other into the two pocket-like widenings 50 a of the receptacle 42 a of the first paneling element 16, to the point where an end face 88 of the connecting plate 58 comes to bear against an inner face of the strip element 32 a. The second paneling element 18 is arranged in such a way adjacent, at a distance S, to the first paneling element 16 that the receptacles 40 a, b lie opposite each other and the connecting elements 22, 24 engage in the pocket-like widenings 50 a, b. The bolts 82 are placed through the through hole 59 of the connecting plate 58 of the first and second connecting elements 22, 24.
Next, the spring element 52, which is provided with the damping element 54, is pressed along the longitudinal direction of the strip elements 32 a, b into the groove-shaped receptacles 42 a, b of the adjacent paneling elements 16, 18. The damping element 54 here faces toward the second strip portion 40 a, b. After this, the connecting bracket 60 is placed against the surface, facing away from the main body 30 a, b, of the second strip portion 40 a, b of the strip element 32 a, b of the first and second paneling element 16, 18, so that the bolt 82 is placed through the connecting hole 70. After this, the nut 84 is screwed onto the bolt 82. The further damping element 70 can here be arranged between that surface of the second strip portion 40 a, b which is facing away from the main body 30 a, b and that surface of the connecting portion 68 which is facing toward the main body 30 a, b.
This process is repeated for the second and third paneling element 18, 20 and the third and fourth connecting element 26, 28.
The now mutually connected paneling elements 16-20 are bolted to the inside 12 of the side wall 14 by the contact plates 70, 72 of the connecting elements 22-28 being placed flush against the inside 12 of the side wall 14, and appropriate bolts being placed through the through holes 76, 78 of the connecting bracket 60 of the connecting elements 20-26 and bolted into the inside 12 of the side wall 14.
Although the invention is more closely illustrated and described in detail through the preferred illustrative embodiment, the invention is not restricted by the disclosed examples and other variants can be derived herefrom by the person skilled in the art, without departing from the scope of the invention.
