Description

[0028] The invention will be better understood upon reading the description which follows, only given as an example and made with reference to the appended figures, wherein:

[0029] FIG. 1 is a schematic longitudinal sectional view of a dining car according to a first exemplary embodiment of the invention;

[0030] FIG. 2 is a schematic cross-sectional view of the dining car of FIG. 1;

[0031] FIG. 3 is a view similar to FIG. 2 of a dining car according to a second exemplary embodiment of the invention.

[0032] A dining car 10 according to a first exemplary embodiment of the invention is illustrated in FIGS. 1 and 2, intended for fitting out a railway vehicle, notably a main line railway vehicle.

[0033] The dining car 10 extends in length in a longitudinal direction X.

[0034] As this is illustrated in FIG. 2, the dining car 10 includes first 12 and second 14 side faces laid out facing each other in a transverse direction Y perpendicular to the longitudinal direction X. These first 12 and second 14 side faces delimit an inner space in the transverse direction Y.

[0035] Each of the first 12 and second 14 side faces is for example respectively formed with first and second structural uprights covered with a trim. Such side faces are standard, and will not be described here in more detail. They are partly open so as to allow the availability of windows.

[0036] The dining car 10 moreover includes a first lower floor 16, delimiting the inner space downwards, in a vertical direction Z perpendicular to the longitudinal X and transverse Y directions.

[0037] This first lower floor 16 defines a lower level 10A of the dining car 10.

[0038] The first side face 12 includes at least one first supporting portion 18 (called << edge>>) intended to support a second upper floor 20. Each first supporting portion 18 is for example formed with an arm extending and protruding from the first side face 12 towards the inner space.

[0039] The second upper floor 20 is attached to each first supporting portion 18, by removable attachment means 19, for example attachment means by bolting. These removable attachment means 19 notably allow a replacement of the second upper floor 20.

[0040] The second upper floor 20 defines an upper level 10B of the dining car 10.

[0041] The second upper floor 20 is for example made in a composite material. Advantageously, this upper floor made removable, may be trimmed << before bolting>> with a floor cladding on one side and a sealing cladding on the other side. This is notably possible because this second upper floor 20 is not assembled by welding to the first supporting portions 18.

[0042] Advantageously, the second side face 14 includes at least one second supporting portion 21, each laid out at right angles from each other from among at least one first supporting portion 18. Each second supporting portion 21 is for example formed with an arm extending and protruding from the second side face 14 towards the inner space.

[0043] According to this first embodiment, each second supporting portion 21 is not used.

[0044] However, according to other embodiments, each second supporting portion 21 forms a support for the second upper floor 20. For example, in an embodiment not described, the second upper floor 20 extends in width between a first side edge secured to the first supporting portions 18, and a second side edge secured to the second supporting portions 21. In this case, the second upper floor 20 is attached to each second supporting portion 21, by removable attachment means, for example attachment means by bolting.

[0045] According to another embodiment not shown, the dining car 10 does not include any second upper floor 20, so that the first 18 and second 21 supporting portions are all unused.

[0046] The dining car 10 includes a first consumption area Z1, a second preparation area Z2, and a third technical area Z3.

[0047] According to the invention, the first Z1, second Z2 and third Z3 areas are all made on the first lower floor 16.

[0048] For this purpose, the second preparation area Z2 and/or the third technical area Z3 are configured so as to be as compact as possible.

[0049] Thus, the upper level 10B is free of any preparation area and of any technical area. This upper level 10B is then available so as to be laid out as desired.

[0050] For example, a fourth consumption area Z4 is laid out on the second upper floor 20. Alternatively, the second upper floor 20 receives at least one conventional room of passengers, at least a meeting room, or any combination of consumption areas, passenger room, meeting room or other room.

[0051] According to the first described embodiment, the second upper floor 20 extends transversely between a first side edge 20A, assembled with each first supporting portion 18, and a second side edge 20B, the second side edge 20B being spaced apart from the second side face 14 by a non-zero distance, so as to delimit a transverse aperture 22 between this second side edge 20B and this second side face 14. Thus, the second upper floor 20 forms a mezzanine extending above the first lower floor 16.

[0052] When the second upper floor 20 forms a mezzanine, it is equipped with a guardrail 23 extending vertically, along the second side edge 20B.

[0053] This second upper floor 20 may receive a fourth consumption area Z4, at least a conventional room of passengers, at least one meeting room, or other room, in the same way as described earlier.

[0054] In order to support the second upper floor 20, the dining car 10 includes at least one vertical upright 24, extending between the first lower floor 16 and the second upper floor 20. Each vertical upright 24 is for example attached to a chassis (not shown) of the carriage 10.

[0055] Advantageously, the second upper floor 20 is formed with a plurality of panels. In this case, each panel is assembled with at least one respective one of the first supporting portions 18, and/or with at least one of the adjacent panels.

[0056] The panels extend together for example over the whole length of the carriage 10, or only alternatively on a portion of the carriage 10, in a continuous way or as a discontinuous alternative.

[0057] It will be noted that each panel has dimensions allowing its passage through a window or a door of the dining car 10.

[0058] In FIG. 3, the dining car 10 according to a second exemplary embodiment has been illustrated. In this figure, the elements similar to those of the previous figures are designated with identical references.

[0059] According to this second embodiment, the dining car 10 includes at least one horizontal cross-piece 26, connecting the second upper floor 20 to the second supporting portion 22. For example, each horizontal cross-piece 26 extends from the second edge 20B as far as this second supporting portion 22.

[0060] In the described example, the horizontal cross-pieces 26 are straight, but they may alternatively be arched, for esthetical reasons.

[0061] It will be noted that the first and second embodiments are compatible, so that the dining car 10 may include both uprights 24 and cross-pieces 26.

[0062] The invention is not limited to the embodiments described earlier, and may have diverse alternatives without departing from the scope of the claims.
