Description

DESCRIPTION

Modular car of a public transport vehicle

The present invention refers to a modular car for a public transport vehicle, specifically a rail vehicle.

A public transport vehicle carriage usually comprises at least one reception room for passengers, this reception room being specifically delimited by side walls and a floor.

In the state of the art, a modular carriage for a railway vehicle is already known, the seating arrangement of which can be modified. Such modular cars are known from the documents FR 3088883 A1 and FR 3039125 A1.

More particularly, the arrangement of the seats can be modified in a longitudinal direction of the car, for example, in order to modify the distance between two adjacent rows of seats, or in order to remove at least one row of seats in order to replace it with a new one. baggage receiving location.

In certain cases, the car can also be modulated by changing the number of seats in a row. Usually, a row of seats comprises, between a side wall and a circulation aisle, between one and three seats. Two rows of seats are arranged next to each other, on both sides of the circulation aisle.

Therefore, a first configuration can be envisaged where the car comprises a row of two seats on one side and a row of a single seat on the other side (first class configuration), a second configuration where the car comprises a row of two seats on each side of the aisle (second class configuration) or even a third configuration where the car comprises a row of three seats on one side and two or three seats on the other side.

The type of seat can also vary from one configuration to another.

More particularly, seats having a first width can be replaced by seats having a second width different from the first.

Therefore, the width of each row, in a transverse direction perpendicular to the longitudinal direction, is liable to change from one configuration to another.

The car comprises side platforms, each extending from a side wall to a circulation corridor defined between these side platforms.

Such platforms are elevated with respect to the circulation aisle, in order to allow the passenger to put his feet on a flat surface.

However, such a car is not entirely satisfactory.

Indeed, the platforms delimit the circulation aisle between them and, therefore, their positioning is different according to the configurations, for example in a second class configuration where the circulation aisle is central, and in a first class configuration where the circulation is closer to one side wall of the car than the other. Accordingly, it is necessary to provide various car configurations that can be changed according to the operating conditions. When one of the configurations is not used, the floor and the platforms related to this configuration must be stored, for example in a maintenance center.

The invention specifically aims to solve this drawback by providing a public transport vehicle car whose modularity is improved, specifically allowing a modularity of the floor when the car includes side platforms.

To this end, the object of the invention is specifically a public transport vehicle carriage, specifically a railway vehicle, comprising at least one reception room for passengers, said reception room comprising: - a first and second side walls, and a floor ,

- the floor comprising a first fixed lateral part, which forms a first platform, and which extends laterally between the first lateral wall and a first edge, the first platform being intended to receive seats for passengers,

- the floor comprising a second fixed lateral part, which forms a second platform, and which extends laterally between the second lateral wall and a second edge facing the first edge, the second platform being intended to receive seats for passengers, and

- the floor comprising a central third part,

wherein the third central part comprises a lower floor element and a raised floor element with respect to the lower floor element, and in that the third central part is removably attached to the first platform and to the second platform,

- the first platform having a first width, defined in a transverse direction, and the second platform having a second width, defined in the transverse direction, the first width being different from the second width, and preferably greater than the second width,

- the raised floor element of the third central part of the floor having a third width defined in the transverse direction, the first width being substantially equal to the sum of the second and third widths. The third central part of the floor makes it possible to increase the effective width of a platform in order to be able to adapt this effective width to the width of a row of seats of a given configuration.

More particularly, the third central part of the floor fixed in a removable manner to the platforms makes it possible to modify the configuration of a car in a simple manner, without storing configuration-specific floor modules. Such a modularity of the car floor makes it possible in particular to go from a first-class floor configuration to a second-class floor configuration, and vice versa.

A car according to the invention may also comprise one or more of the following characteristics, taken alone or in any technically foreseeable combination:

- the lower floor element and the raised floor element form a single piece,

- the third central part is fixed by bolting to the first platform and to the second platform, - the raised floor element comprises at least a first fixing zone to the first platform or to the second platform, the first fixing zone extending longitudinally in the vicinity of a longitudinal free edge of the raised floor element,

- the third central part comprises a second vertical panel that has at least a second fixing zone to the first platform or to the second platform, the second fixing zone extending longitudinally in the vicinity of a longitudinal free edge of the second vertical panel,

- the carriage comprises an upper deck and a lower deck, the lower deck delimiting said reception room. The object of the present invention is also a procedure for changing the configuration of the floor of a public transport vehicle car according to any one of the previous claims, which comprises removing the fixings of the third central part to the first platform and to the second platform, the pivoting of the third central part through 180° in a longitudinal plane, and the fixing of the third central part thus pivoted to the first platform and to the second platform.

The invention will be better understood after reading the following description, provided solely by way of example, and made with reference to the attached figures, where:

FIG. 1 is a partial sectional view of a public transport vehicle coach according to an embodiment of the invention, in a first configuration;

figure 2 is a view similar to figure 1 of the car in a second configuration; and

- figure 3 is a perspective view of a floor in the configuration of figure 1.

In the description below, the term "public transport vehicle" comprises a railway vehicle, a guided land vehicle, a bus, a naval vehicle.

Preferably, the public transportation vehicle is a double-decker rail vehicle.

Figures 1 and 2 show a carriage 10 of a public transport vehicle, specifically a railway vehicle. This car 10 extends in a longitudinal direction X.

Car 10 is, for example, a double-decker car, comprising an upper deck (not shown) and a lower deck 12 . In a variant, the carriage 10 only has one floor. In the case where the car only has one floor, this is identical to the floor 12 defined in the present description.

The floor 12 delimits a reception room 14 for passengers, this reception room 14 being specifically delimited by a first side wall 16, a second side wall 18 facing the first side wall 16 in a transverse direction Y perpendicular to the longitudinal direction X , and a floor 20.

The floor 20 comprises a first side part 22, a second side part 24 and a third central part 26 between the first side part 22 and the second side part 24.

The first side part 22 is fixed.

The first side part 22 forms a first side platform 22, which extends laterally between the first side wall 16 and a first edge 22A. This first platform 22 is intended to receive first seats 25 for passengers and, more particularly, first rows 28 of seats aligned in the longitudinal direction X. The first platform 22 has a first width L1, defined in a transverse direction Y.

In a first configuration shown in Figure 1, each first row 28 comprises two first seats 25. The first configuration is, for example, a "first class" configuration.

In a second configuration, shown in Figure 2, each first row 28 comprises two first seats 25. The widths of the seats 25 can vary depending on the configuration.

The second configuration is, for example, a "second class" configuration.

Typically, the seats in a “first class” configuration (figure 1) are larger than the seats in a “second class” configuration (figure 2).

Therefore, each first row 28 of the first configuration has a width, taken in the transverse direction, greater than the first row 28 of the second configuration.

The second side part 24 of the floor 20 is fixed.

The second side part 24 forms a second side platform 24, which extends laterally between the second side wall 18 and a second edge 24A facing the first edge 22A, the second platform being intended to receive second passenger seats and, more particularly, second rows 30 of seats aligned in the longitudinal direction X. The second platform 24 has a second width L2, defined in the transverse direction Y, the first width L1 being different from the second width L2, and preferably greater than the second width L2. In the first configuration represented in figure 1, each second row 30 comprises a second seat 31 of the "first class" type, which is relatively large. This second first class seat 31 is, for example, identical to one of the first first class seats 25 .

In the second configuration, shown in FIG. 2, each second row 30 comprises two second seats 31 of the "second class" type, each having a width less than that of a second "first class" seat 31 . Each second 31 second class seat is, for example, identical to one of the first 25 second class seats. The row 30 of the first configuration has a width, taken in the transverse direction Y, less than the row 30 of the second configuration, which includes two seats 31.

The present invention allows the width of the rows 28, 30 to be changed in order to pass from one configuration to another, despite the presence of the platforms 22, 24.

For this, the floor 20 comprises a third central part 26 comprising a lower floor element 32 and a floor element 34 raised with respect to the lower floor element 32, as represented in figure 3. The floor element 32 bottom and raised floor element 34 form a single piece.

The raised floor element 34 comprises at least a first area 35 for fastening to the first platform 22 or to the second platform 24.

For example, the first fixing zone 35 extends longitudinally in the vicinity of a longitudinal free edge 36 of the raised floor element 34 .

The lower floor element 32 and the raised floor element 34 are connected, for example, by a first vertical panel 37 extending from a first longitudinal edge 38 of the lower floor element 32. Preferably, the third central part 26 comprises a second vertical panel 40 that has at least one second fixing area 42 to the first platform 22 or to the second platform 24.

In particular, the first vertical panel 37 has a height H1 identical to a height H ₂ of the second vertical panel 40. For example, the second fixing zone 42 extends longitudinally in the vicinity of a longitudinal free edge 43 of the second vertical panel 40.

The second vertical panel 40 extends from a second longitudinal edge 44 of the lower floor element 32. Thus, the third central part 26 can be removably attached to the first platform 22 and to the second platform 24.

For example, the third central part 26 is fixed by bolting to the first platform 22 and to the second platform 24.

The raised floor element 34 of the central third part 26 of the floor 20 has a third width L3 defined in the transverse direction Y, the first width L1 being substantially equal to the sum of the second L2 and third L3 widths.

Therefore, when the central third part 26 of the floor 20 is fixed so that the raised floor element 34 is fixed to the first platform 22 of first width L1, the assembly formed by the first platform 22 and the raised floor element 34 it has a width greater than the second width L2 of the second platform 24. It is normally in a "first class" configuration.

Alternatively, when the central third part 26 of the floor 20 is fixed so that the raised floor element 34 is fixed to the second platform 24 of second width L2, the assembly formed by the second platform 24 and the raised floor element 34 has a width substantially equal to the first width L1 of the first platform 22. It is normally in a "second class" configuration.

A configuration change procedure of the ground 20 of a public transport vehicle car 10 will now be described.

Initially, the fixings of the third central part 26 to the first platform 22 and to the second platform 24 are removed.

The central third part 26 is raised, then pivoted 180° in a longitudinal XY plane. For example, this stage is carried out by one or more operators.

The central third part 26 pivoted in this way is fixed again to the first platform 22 and to the second platform 24. The raised floor element 34 is fixed to the first platform 22 or to the second platform 24 in the first fixing zone 35 .

The second vertical panel 40 is fixed to the first platform 22 or to the second platform 24 in the second fixing zone 42.

Thanks to the invention, it is not necessary to store unused flooring, the transition from one configuration to another is done simply and quickly.

The safety of the operators is also improved and the useful life of the floors is increased, since it is not necessary to remove them from the car or from the storage place to modify the configuration of the car.
