Abstract
Description
Technical Field
[0001] The invention relates to a body for a transport vehicle, in particular a rail transport vehicle, comprising a floor support structure, at least one side wall, a gasket arranged at a junction between the support structure and the side wall, a covering layer arranged on the support structure and a facing cap covering a boundary of the covering layer. Background Art
[0002] Typically, the floor of a rail vehicle comprises a visible covering of the carpet or linoleum type which gives the vehicle a certain comfort and a particular aesthetic. This visible covering is adapted to the finish of the vehicle. For example, the carpet for the first class of a train carriage is usually thicker than the carpet for the second class.
[0003] From US-A-2,559,443 it is known to press a visible covering onto the supporting structure of a rail vehicle while raising such a covering along the side walls of the vehicle, the upper border of the covering being attached using rods mounted on the side walls close to the windows. In the transition area between floor and side walls, the covering is continuously supported by the metal sheet forming the cavity, the covering being uninterrupted in this area. The rods for fastening the borders of the covering are adapted to the individual covering thicknesses.
[0004] It is also known from EP-A-2,266,858 to manufacture a toilet unit for railway vehicles by inserting a gasket at the junction between the floor and the side walls of the toilet unit. The facing bars are clamped onto the gasket and cover the floor covering. This system can prevent water from penetrating the junction area between the floor and the side walls, but it cannot guarantee tightness at the facing bars or accommodate floor coverings of varying thicknesses.
[0005] Other systems provide for the use of profiles with a specific geometry covering a given thickness. The use of these profiles with a specific geometry based on the covering leads to an increase in the number of parts to be provided for the production and maintenance operations of the body of the vehicle.
[0006] The present invention more specifically aims to solve these drawbacks by proposing a new body for a vehicle, in particular a rail vehicle, which, thanks to a simple structure that can be used with visible coverings of different thicknesses, is able to provide a high level of finish and prevent the flow of water into the structure of the body, without having to use a large number of different spare parts. Summary of the invention
[0007] To this end, the present invention relates to a body for a means of transport of the aforementioned type, wherein a cap is preferably removably fastened to the side wall and defines with the gasket a gap for receiving the boundaries of a covering layer, while the relative position of the cap and the gasket is adjustable and the width of the gap varies based on the relative position of the cap relative to the gasket.
[0008] Thanks to the invention, the structure of the body is compatible with use in different configurations, in particular with visible coverings of different thicknesses adapted to the different comfort levels of the means of transport, while ensuring an effective seal preventing the ingress of wash water into the junction area of floor and side walls or even into the floor and visible covering. These advantages are obtained by means of caps and gaskets that can be used in different configurations, which avoids having to manage different component references during production and maintenance of the body according to the invention.
[0009] According to an advantageous but optional aspect of the invention, such a subject may incorporate one or more of the following features considered in any technically permissible combination:
[0010] The means for fastening the facing cap to the side wall comprise at least one oblong hole arranged in a first element in the cap and in the side wall and a screw engaging in the oblong hole and in another hole arranged in a second element in the cap and in the side wall.
[0011] - The gasket is integral with the side wall or supporting structure.
[0012] - The spacer is a component attached to the side wall or the supporting structure, preferably in the form of a profile.
[0013] The side wall comprises a housing for partially receiving the cap, preferably in a configuration in which the face of the cap facing the inner volume of the body is flush with the face of the side wall situated in the extension of the receiving housing and facing the inner volume.
[0014] The cap is arranged to be mounted on the side wall in at least two positions, namely a first high position and a second low position closer to the gasket than the first high position.
[0015] -The cap is in its first highest position in the receiving portion, the upper edge of the cap is in contact with the upper edge of the receiving portion, and the face of the cap facing the internal volume body of the main body and the face of the side wall located in the extension of the receiving portion and facing the internal volume body are flush, with no gap between them.
[0016] The cap is equipped with a bottom plate that slides on the bottom of the housing, which bottom plate provides surface contact with the bottom of the housing, regardless of the relative position of the cap with respect to the gasket.
[0017] The upper side surface of the gasket on which the lower portion of the border of the covering layer is pressed is generally parallel to the lower surface of the cap resting on the upper portion of the border of the covering layer, regardless of the relative position of the cap with respect to the gasket.
[0018] According to another aspect, the invention relates to a method for installing a body as described above, the method comprising the step of adjusting the relative position of the cap with respect to the spacer so as to adjust the width of the gap according to the thickness of the border of the covering layer.
[0019] This method brings about the same advantages as described above with respect to the subject matter of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0020] The invention will be better understood and other advantages thereof will appear more clearly in view of the following description of one embodiment of the body and assembly method according to the principles of the invention, provided purely as an example and made with reference to the accompanying drawings, in which:
[0021] - Figure 1 is a partial cross-sectional view of a joining area between a floor and one of the side walls of a body of a rail vehicle according to the present invention, the floor comprising a carpet layer having a first thickness;
[0022] - Figure 2 It is along Figure 1 A front view detail of arrow II;
[0023] - Figure 3 is similar to Figure 1 A view of a floor comprising a carpet layer having a second thickness, the second thickness being less than Figure 1 The thickness of the carpet layer; and
[0024] - Figure 4 is similar to Figure 2 Along Figure 3 Detailed front view of arrow IV in FIG. DETAILED DESCRIPTION
[0025] The figures partially show a railway vehicle body 2 according to the invention. The body comprises a floor 4 and two side walls, only one of which is shown in the figures with reference numeral 6. The figures show the junction area between the floor 4 and the side wall 6.
[0026] The floor panel 4 comprises a supporting structure 8 and a visible covering layer 10 , here formed by a carpet, the thickness of which is indicated as e10 .
[0027] The wall 6 is a double-layer structure having an outer partition 62 and an inner partition 63 connected to each other by a bottom 64. The bottom rests on the upper surface 82 of the support structure 8. Near the bottom 64, the inner partition 63 has a recess 632 facing the outer partition 62. The recess 632 defines a housing 65 for receiving the cap 12 on the inner side of the inner partition 63.
[0028] The parts 10 , 12 and 63 delimit an internal volume V2 of the body 2 in the junction region between the floor 4 and the side wall 6 .
[0029] The cap 12 is composed of a bottom plate 122 and a tongue piece 124. The tongue piece 124 constitutes the lower part of the cap 12 and is folded downward toward the volume body V2.
[0030] The gasket 66 is arranged at the bottom of the recess 632 below the cap 12 .
[0031] In this example, the spacer 66 is integral with the inner partition 63, which in turn is integral with the bottom 64 and the outer partition 62. Like the bottom 64, the spacer 66 rests on the upper surface 82 of the support structure 8, which enables it to absorb forces having a downward vertical component.
[0032] Reference numeral 126 denotes the surface of the tongue 124 facing the gasket 66. Reference numeral 662 denotes the upper side surface of the gasket 66 facing the tongue 124. The surfaces 126 and 662 define a gap 500 between them. Reference numeral 1500 denotes the width of the gap 500, i.e., the dimension of the gap 500 measured perpendicularly between the surfaces 126 and 662.
[0033] In this example, the upper side surface 662 of the gasket 66 on which the lower portion of the cover layer 10 abuts is generally parallel to the surface 126 of the cap 12 facing the gasket 66 on which the upper surface of the cover layer 10 abuts. Generally parallel means that the surfaces 662 and 126 are parallel within a range of 10°, preferably within a range of 5°.
[0034] The surface 662 has a curved profile in a section perpendicular to the longitudinal axis X66 of the gasket 66, the concavity of which faces the surface 126. The thickness of the gasket 66 measured along the height direction of the body increases as it approaches the wall 6, in particular the recess 632 (ie, at Figure 1 and Figure 3 Increases from the center to the left).
[0035] The cap 12 is also pierced with an oblong hole 128, the largest dimension of which has a vertical axis. Figure 2 and Figure 4 Only one oblong hole 128 is shown, but in reality, a plurality of oblong holes 128 are arranged along the length of the cap 12, which is perpendicular to the cap 12. Figure 1 and Figure 3 of the plane and Figure 2 and Figure 4 It is shown by its longitudinal axis X12.
[0036] Axes X12 and X66 are parallel.
[0037] The shank of the screw 14 passes through the oblong hole 128 and is screwed into the nut 16 connected to the inner partition 63 on the side of the inner partition 63 facing the outer partition 62. The nut 16 is connected in the recess 632 opposite to the circular hole by welding or any other method to allow the shank of the screw 14 to pass through.
[0038] Given the oblong nature of the aperture 128, it is possible to Figure 1 and Figure 2 The first extreme position shown is Figure 3 and Figure 4 The position of the cap 12 in the receiving portion 65 is vertically adjusted between the second extreme lower position shown.
[0039] Regardless of the relative position of the cap 12 with respect to the gasket 66 , the bottom plate 122 of the cap 12 provides surface contact with the bottom of the receiving portion 65 formed by the recess 632 to facilitate the positioning operation of the cap 12 during assembly or maintenance of the body 2 .
[0040] exist Figure 1 and Figure 3 In the embodiment, a receiving portion 65 is provided so that the bottom plate 122 of the cap 12 is fully inserted therein, that is, the inner face 121 of the cap 12 facing the inner volume V2 of the main body 2 is flush with the inner face 631 of the inner partition 63 of the side wall 6 located above the receiving portion 65 and facing the inner volume V2. Flush means that the faces 121 and 631 are aligned and coplanar. Therefore, from the perspective of the inner volume V2, the surfaces 631 and 121 are continuous with each other, which improves the aesthetics of the wall 6 and facilitates its cleaning.
[0041] The receiving portion 65 for partially receiving the cap 12 is in the extension of the wall 63 , and the bottom of the receiving portion 65 close to the recess 632 is parallel to the surface 631 of the side wall 6 .
[0042] Regardless of the relative position of the cap 12 relative to the gasket 66, the bottom plate 122 of the cap 12 provides surface contact with the bottom of the accommodating portion 65, and the face 121 of the cap 12 facing the internal volume body V2 of the main body 2 is flush with the face 631, regardless of the relative position of the cap 12 relative to the gasket 66.
[0043] From one side Figure 1 and Figure 2 with the other party Figure 3 and Figure 4 It can be seen from the comparison that the main body 2 of the present invention may include Figure 1 The relatively thick cover layer 10 shown or Figure 3 The relatively thin cover layer 10 shown. In other words, the thickness e10 of the cover layer 10 is Figure 3 and Figure 4 In the structure of Figure 1 and Figure 2 In the case where the constituent elements of the body 2 are identical, the invention can accommodate these two values of thickness e10 of the cover layer 10 .
[0044] exist Figure 1 and Figure 2 In the first configuration, the cap 12 is positioned relatively far from the spacer 66 so that the width 1500 of the gap 500 assumes a relatively large first value suitable for the relatively large value of the thickness e10. This allows the boundary 102 of the cover layer 10 to be accommodated in the gap 500 between the surfaces 126 and 662. Figure 3 and Figure 4 In the second configuration, the cap 12 is positioned relatively close to the gasket 66, i.e., closer to the gasket 66 than in the first position, so that the width 1500 of the gap 500 assumes a relatively small second value suitable for the relatively small value of the thickness e10. This makes it possible to accommodate the boundary 102 of the cover layer 10 in the gap 500 between the surfaces 126 and 662 without leaving a gap through which wash water can penetrate. In both configurations, the lower surface of the boundary 102 abuts against the surface 662, while its upper surface abuts against the surface 126.
[0045] Therefore, the adjustable nature of the relative position of the cap 12 with respect to the gasket 66 makes it possible to adjust the width l500 of the gap according to the thickness e10 of the cover layer 10. The cap 12 effectively protects the border 102 from the flow of wash water. Therefore, the internal structure of the body 2 is protected from moisture. In particular, there is no risk of water penetrating under the cover layer 10 or between the bottom 64 and the support structure 8.
[0046] This achieves tightness without the use of putty and even in Figure 1 and Figure 2 as well as Figure 3 and Figure 4 Using the same components in the two configurations shown respectively, the body 2 is compatible with covering layers 10 (e.g. carpet) having a relatively large thickness, for example in first class, and with covering layers 10 (e.g. carpet) having a smaller thickness, for example in second class.
[0047] In addition to the geometry of the gasket 66, its thickness increases as it approaches the side wall 6, tending to direct the liquid toward Figure 1 and Figure 3 The inner surface of the cover 10 is returned to the right side (ie towards the inner volume V2), thereby preventing the flow of liquid at the junction of the support structure 8 and the side wall 6 or between the support structure 8 and the cover 10.
[0048] exist Figure 1 and Figure 2In the configuration of , the upper edge 123 of the cap 12 is in contact with the upper edge 653 of the receiving portion 65, so that no gap is formed at this level where dust or dirt may accumulate. Figure 3 and Figure 4 In the configuration of , a gap 600 is formed at this level. Figure 1 and Figure 2 The most aesthetically pleasing finish is provided in the construction of the cabin (i.e., in this example, in the case of a first-class cabin).
[0049] During assembly of the body 2, the cap 12 is placed in contact with the Figure 1 and Figure 3 500 to allow the border 102 of the cover 10 to be inserted into the gap 500, and then, if necessary, the cap 12 is lowered until the surface 126 presses against the border 102 of the cover 10 or provides sufficient compression to the border 102 of the cover 10 so that the expected performance in terms of maintenance and sealing of the cover 10 can be obtained. The final position of the cap 12 can account for any compression of the border 102 of the cover 10 between the components 12 and 66.
[0050] It should be noted that the cap 12 may be located between Figure 1 and Figure 2 The position shown is Figure 3 and Figure 4 Any position between the positions shown, which can adapt the construction of the body 2 to the thickness e10 of the carpet 10 between the thicknesses of the carpet 10 shown in the figures. In this intermediate position of the cap 12, the lower part of the border 102 also abuts on the surface 662, and the upper surface of the border 102 also abuts on the surface 126.
[0051] According to a variant that is not shown here, the spacer 66 could be integral with the supporting structure 8 of the floor 4 and not with the wall 6 .
[0052] According to another variant, the spacer 66 can be a part attached to the side wall 6 or to the supporting structure 8. In this case, the spacer 66 can be made, for example, in the form of a profile made of metal or synthetic material and arranged at the junction between the supporting structure 8 and the side wall 6 and optionally fixed by temporary means, which can optionally be repositioned, such as adhesive strips, or by permanent means such as welds or any other equivalent means.
[0053] According to a variant not shown, the oblong hole 128 can be arranged in the recess 632 of the side wall 6. In this case, only one circular hole for the shank of the screw 14 to pass through can be pierced in the cap 12. In a variant, oblong holes are arranged both in the cap 12 and in the recess 632.
[0054] According to another variant, the upper side surface 662 of the gasket 66 is Figure 1 and Figure 3 The surface 126 may have a rectilinear profile in the plane of the embodiment of the present invention, or any other arch having an elliptical or curved shape with its concavity facing the inner volume V2 or facing away from the inner volume V2. In this case, the shape of the surface 126 is adjusted.
[0055] According to another variant, the carpet layer 10 may be replaced by a layer of linoleum or another visible covering covering the supporting structure 4 .
[0056] According to yet another variant, in the absence of any covering layer, when the cap 12 is in its second extreme lower position, the surface 126 is in contact with the surface 662 .
[0057] The invention has been described above in the context of its implementation in a rail vehicle body, i.e. a passenger train carriage. It can be implemented in other rail vehicles, such as trams, and more generally in vehicles, in particular vehicles for public transportation, such as buses, ferries or airplanes.
[0058] The above-mentioned embodiments and modifications can be combined with each other to form new embodiments of the present invention.
