Description

The utility model relates to railway transport, in particular, to the construction of double-decker passenger cars, which, in comparison with single-decker ones, provide a more rational use of the size of rolling stock and increase the carrying capacity of passengers on railway lines at a minimum cost.

Double-decker wagons have been widely used in many countries since the middle of the last century both in suburban communication and in long-distance trains as sleeping wagons. Their use provides a number of advantages, such as reducing the length of a train from double-decker cars by about 1.5-2 times less than trains from single-deck cars with the same number of seats and their sizes, reducing the cost of inspection, cleaning and maintenance of cars, reducing the need for sludge tracks, reducing their length at technical stations, as well as reducing the length of landing platforms.

However, this raises the problem of ensuring fast, reliable and convenient entry and, mainly, the exit of passengers from the upper passenger compartment.

A two-story passenger carriage is known, comprising a body mounted on the chassis, the central part of which is divided by longitudinal horizontal overlap into upper and lower passenger cabins located at the end parts of the body above the trolleys side entrance doors, to the platforms in front of which (vestibules) are stairs from the upper and lower passenger salons [1].

Boarding and disembarking passengers of both the upper and lower passenger cabins is carried out through two doors located on opposite sides of the car. Even if there are platforms on both sides of the car, the exit of passengers through two doors is long and not very convenient even when expanding the doorway, and the longitudinally oriented stairs leading to the entrance doors from the lower and upper passenger compartments take up a lot of space due to the need to install them with acceptable angle of inclination, limiting the number of passenger seats in the car.

A two-story passenger carriage is also known, comprising a body mounted on the chassis, divided by longitudinal horizontal overlap into upper and lower passenger cabins, leading from them to the platform of the vestibules with longitudinal stairs located in each of them with two doors and an elevator installed next to the vestibule between the floors of the car [ 2].

The increase in the number of doors (two at each end of the car) partially solves the problem of accelerating the entrance (exit) of passengers, and the presence of an elevator between the upper and lower salons makes it more convenient, especially for passengers with reduced mobility, but this is not enough to quickly exit passengers from the car, in particular, in case of emergency.

The closest to the claimed car, in technical essence, is a two-story passenger car, containing a load-bearing body mounted on the chassis, divided by a longitudinal horizontal overlap into upper and lower passenger cabins with a longitudinal corridor in each of them,

and located between the floor and the floor of the car in the transverse direction relative to the body of the staircase for passage from the upper passenger compartment to the entrance doors installed in the side walls of the body at the ends and in the central part of the car at the level of the lower floor [3].

In this well-known carriage, a separate exit of passengers from the upper passenger compartment is arranged along the longitudinal corridor and along the stairs descending to the lower compartment level and located in the transverse direction at the ends of the carriage to the exit doors located on both sides of the carriage, and also descent along the central transverse staircase is possible to the central part of the lower passenger compartment, where twin doors are located on both sides of the body, through which the exit of passengers of the lower and partially upper fat a.

A large number of entrance doors (four at the ends of the body and four in its central part), a separate exit for passengers in the upper cabin provide the opportunity, if necessary, for a quick and organized exit of passengers from the car without unnecessary hustle and crush, but the stairs located in the ends of the body are quite steep ( installed at a large angle), and their lower parts (last steps) end directly in front of the doors, i.e. with the door open immediately below them there is a gap between the body and the landing platform, which makes the exit uncomfortable and not safe enough. In addition, the implementation of the opening for placing stairs in the longitudinal overlap of the body almost the entire width reduces the load-bearing capacity of the body.

The technical result that can be achieved by using the claimed utility model is to provide a quick, safe and convenient exit for passengers of a double-decker car while reducing the degree of weakening of the body and the internal volume of the body to accommodate the interfloor transition.

To achieve this result, in a two-story passenger carriage containing a load-bearing body mounted on the chassis, divided by longitudinal horizontal overlap into upper and lower passenger salons with a longitudinal corridor in each of them, and transverse stairs located between the ceiling and the floor of the car for passage from the upper passenger compartment to the doors installed in the side walls of the body at the level of the lower passenger compartment, it is proposed that the lower part of at least part of the stairs be executed as linen section located under the upper part of the stairs rigidly fixed in the body with the possibility of extension with the door open onto the landing platform.

The extension of the lower section of each staircase can be carried out in a horizontal plane before the docking of its upper part with the lower part of the fixed section of the staircase.

The lower section of each staircase can be equipped with a drive for its extension, synchronized with a drive for opening doors.

The longitudinal corridor of the upper passenger compartment can be made lateral or central, in the latter case, the stairs leading to the entrance doors of the car can be located on either side of it.

A possible design of the claimed utility model is presented in the accompanying drawings.

Figure 1 - shows the end of the car at a high platform.

Figure 2 - shows a cross section of a car.

Figure 3 - embodiment of a car with central corridors on the floors.

A two-story passenger carriage contains a load-bearing body 1 mounted on the chassis 2. Inside, the body 1 is divided by a longitudinal horizontal overlap 3 into an upper passenger compartment 4 and a lower passenger compartment 5 with a longitudinal corridor 6 in each of them.

In salons 4 and 5, seats for passengers can be installed or coupes with sleeping places (not shown in the drawings) can be equipped.

To enter and exit passengers from the upper passenger compartment 4, stairs 8 are installed between the ceiling 3 and floor 7 of the body 1, leading to the doors 9 located in the side walls of the body 1 at the level of the lower floor.

To increase the number of passenger seats in the car, increase the compactness and ease of use of the input devices, it is preferable to laterally place the stairs 8 inside the body 1, however, this will weaken the body 1, part of the power reinforcing elements 10 of the ceiling 3 are cut by the stairwell.

To minimize this and ensure a reliable and convenient exit from the upper passenger compartment, at least a part of the stairs 8 of the car is made of two parts: the upper part 11 rigidly fixed in the body and

a separate section 12 located below on the floor 7 with the possibility of its extension with the door 9 open towards the landing platform 13.

The extension of the section 12 can be carried out, for example, using the drive 14 in the horizontal direction until the upper part of the section 12 joins the upper part 11 with the door 9 open.

From the point of view of this goal, it is preferable to perform the corridor 6 in the upper passenger compartment 4 lateral, but it is also possible to perform the central one (Figure 3).

To enter (exit) passengers at stops after opening doors 9, the lower section 12 of the staircase 8 is extended with the railing 15, and the gap between the car body 1 and the platform 13 is closed, which, together with a small angle of inclination of the staircase 8 (fairly gentle) provides a convenient and safe entry and, especially, the exit of passengers from the upper passenger compartment 4, simultaneously with the exit of passengers from the lower passenger compartment 5 through the central doors (not shown in the drawings).
