Description

The present invention relates to a set of seats for a railway carriage, comprising a casing partially covering the box-like structure of the carriage trolley located above the trolley, and this casing forms the seat and back frames of two seats mounted back to back.

Known railway carriage containing such a casing in which two seats are formed, placed back to back. In each seat of each seat in the casing form a stiffener. The stiffening element is performed by placing the comfort element of the seat. An element of comfort runs along the seat and back of each seat in each chair. The comfort element of the seat is thus attached to the surface forming the base of the cavity and is surrounded by a protruding edge that forms a bulge around this cavity. Thus, a protruding edge is located around the comfort element of each seat.

However, such a casing is expensive, since in the manufacture of each cavity, casting operations are necessary. In addition, such a casing is not sufficiently adapted to changes in the comfort of the passenger seat, namely, the thickness of the comfort elements and the width of the seats. This design also does not allow you to easily change the appearance of the seats, while the shape of the comfort element of the seat depends on the shape of the stiffener created in the casing.

The aim of the invention is to eliminate the above disadvantages by selling a car containing a set of inexpensive seats, the comfort and aesthetic appearance of which could easily be changed.

In this regard, the object of the present invention is a set of seats for a railway carriage, which contains a casing partially covering the box-like structure of the carriage of the carriage, while this casing forms the seats and backs of two seats located in opposite directions, characterized in that the surface of the seats and the surface of the backs each seat does not have violations of the plane of inclination, as well as the fact that at least one passenger can be placed in each chair.

According to other methods of carrying out the invention, the lantern has one or more of the following characteristics, taken individually or in accordance with any possible technical combinations:

- at least one comfort structure is placed on at least one chair and extends along the surface of the seat and / or on the back surface of the chair;

- at least one chair forms one bench, designed for a certain number of seats;

- at least one chair contains one comfort element for each seat of the chair;

- at least one chair contains one element of comfort, distributed over several seats, at least one chair;

- this design of comfort contains at least one separate part, including one separate part to ensure comfort of the seat and a separate part to ensure comfort of the back;

- this set of chairs has at least a comfort structure comprising a separate part for providing seat comfort and a separate part for ensuring back comfort, while this comfort structure forms a single unit continuously passing over the surface formed by the surface of the seat and the surface of the back of the chair;

- a kink of the inclined plane separates the surface of the seat from the surface of the back of at least one chair.

The object of the invention is also a railway carriage containing at least one set of seats of the aforementioned type.

A railway carriage according to the invention has any of the following distinguishing features, one single or individually taken:

- it contains a second set of seats; however, this second set is placed on the box-shaped structure of the trolley; while the box-shaped structure is adjacent to the first side wall and is located in front of the first pair of wheels of the trolley, located one after another next to this wall; each set contains a casing located against the wheel; while the two structures are symmetrical to each other with respect to the transverse vertical plane N, forming a median plane between the wheels;

- it contains a second pair of sets of seats located above the second box-shaped structure of the trolley and installed along the second side wall of the car.

In the description, the term “height” is defined with respect to a rail along which a railway carriage moves in a substantially vertical direction in which the car is mounted on rails. The concepts of “longitudinal”, “transverse”, “lower” and “upper” are defined with respect to the directions in which the railway car is usually mounted on rails.

Figure 1 shows a side section of a part of a railway carriage mounted on a trolley 2. The trolley 2 is located under the casing of the railway carriage 1 and ensures its retention on rails and movement along them.

The cart contains two pairs of wheels 101, 101 ', one of which is shown in figure 1. Each pair of wheels has two wheels located one after the other in the longitudinal direction of the car. Two pairs of wheels in the transverse direction are installed at a certain distance from each other, while the first pair is located next to the first side wall 50 of the car, and the second pair of wheels is next to the second side wall 500 of the car, which is opposite the first side wall 50.

Wagon 1 comprises a floor 4, forming a corridor for moving passengers, and a chassis 5, which has a lower part 7. The lower part 7 is placed essentially horizontally and is designed to be located opposite the rail along which the railway car 1. The chassis 5 contains a box structure 3 of the trolley , which forms a solid structure rising above the lower part 7, elongated upward relative to the lower part 7 and forming a cavity designed to accommodate the trolley 2. The box-shaped structure for the trolley is located dy two vertical walls - a front wall and back wall T T '. The front walls T and T 'are installed in the transverse direction between the side 50 and the longitudinal wall L shown in FIGS. 2 and 3. The longitudinal wall L, being in a vertical position, is located in the longitudinal direction of the car and is essentially parallel to the side wall 50.

The section of the box-shaped structure 3 (shown in FIG. 1) is the same over the entire width of the box-shaped structure, which also applies to the section of the longitudinal wall.

The box-shaped structure 3 comprises a first protrusion R formed against the wheel 101. The protrusion R is longitudinally extended from the front wall T to the intermediate surface 9, and in the transverse direction, from the side wall 50 to the longitudinal wall L.

The box structure 3 comprises a first protrusion R ′ formed opposite to the wheel 101 ′. The protrusion R 'in the longitudinal direction is extended from the rear wall T' to the intermediate surface 9, and in the transverse direction from the side wall 50 to the longitudinal wall L.

The intermediate surface is essentially horizontal and elongated in the transverse direction from the side wall 50 to the longitudinal wall L.

Each protrusion inside the car forms surfaces that protrude relative to the lower part 7. In these protrusions, wheels 101 and 101 'can be placed below the chassis of the car.

The second box structure 300 is located opposite the cart 2. In particular, the second box structure is placed against the second pair of wheels 101, 101 'of the cart 2 mounted along the second side wall 500, which is opposite the first side wall 50.

Part of the floor 4, as shown in figure 2, is located between the box structures 3 and 300.

The first casing 6 and the second casing 6 ', each separately, partially cover the first box-shaped structure 3. The casing 6 covers the protrusion R, and the casing 6' - the protrusion R '.

The casing 6 and, accordingly, the casing 6 'form a block that contains a Central cavity in which the protrusion R, respectively, R' are located, when the casing covers the protrusion R.

The casing R in the transverse direction is located between the wall 50 and the transverse wall 70, and in the longitudinal direction between the first vertical wall 15 and the vertical wall 16. The block 6 contains, as will be seen later, above the walls 50, 70, 15 and 16 a towering continuous the surface formed by the seats of two seats 10 and 11 and their backs, respectively 20 and 21, as well as the transverse wall 27. In addition, the block 6 is mounted on the protrusion R, while this protrusion R is placed in the cavity of the block 6 between the aforementioned walls.

The casing R 'in the transverse direction is located between the wall 50 and the transverse wall 70', and in the longitudinal direction between the first vertical wall 15 'and the vertical wall 16'. Block 6 'contains, as will be seen later, above the walls 50, 70', 15 'and 16' an elevated continuous surface formed by the seats of two seats 10 'and 11' and their backs, respectively 20 'and 21', as well as a transverse wall 27 '. In addition, when the block 6 'is mounted on the protrusion R', this protrusion R 'is located in the cavity of the block 6 between the aforementioned walls.

The first 6 and second 6 'casings are designed to provide heat and sound insulation inside the car.

As shown in FIG. 3, the casing 6 forms a set of 8 seats 10 and 11. The second casing 6 'forms a second set of 8 chairs.

Figure 2, which shows a top view of part of the car 1, shown in figure 1, shows a second pair of sets 80 and 80 'of seats, the structures of which are formed, respectively, by casings 60 and 60', located opposite the casing 300.

Sets 80 and 80 'are symmetrical, respectively, to sets 8 and 8' in the longitudinal vertical plane passing through the median vertical plane M of the car.

An option may be considered when, depending on the design of the trolley 2, two box-shaped structures placed above the trolley 2 can have different widths, as a result of which the sets of chairs located on these two box-shaped structures have different widths and are not symmetrical with respect to the plane M.

Figure 3-7 shows all the structural elements of the seats 10 and 11.

Two sets of 8 and 8 'are symmetrical to each other with respect to the plane N (shown in figure 1), which is essentially vertical and elongated in the transverse direction of the car.

In the following, only a set of 8 seats will be described, the structure of which is formed by the casing 6, while the set of 8 'chairs is symmetrical to the set 8' relative to the plane N and contains the same elements as the set 8 located symmetrically to the elements of the set 8 'relative to the plane N.

Similarly, seat sets 80 and 80 'are symmetrical to each other with respect to the plane N.

Only the elements of the set of 8 seats will be indicated by reference numbers.

Set 8 contains the first chair 10 and the second chair 11. The first casing 6 forms the structure of the set of 8 chairs 10, 11. To be more precise, the casing 6 carries the structural functions of the seats and backs of chairs 10 and 11.

Both the first 10 and second 11 chairs form a bench. Each of the banquets 10 and 11 is made in such a way that it has one person or several people sitting next to each other. Indeed, each of the two banquets 10 and 11 is elongated in the transverse direction to a sufficient width so that each of them can be occupied by two people, thus, they contain two seats.

The second bench 11 is oriented in the direction of the second casing 6 ', and the first bench 10 is in the direction opposite to the second casing 6'.

The first casing 6 contains a lower structural part 12 forming the seats of two seats 10 and 11, the longitudinal section of which is in the form of the letter S. In particular, the lower part 12 contains two upper walls, generally horizontally located on both sides of the upper part 19 of the casing 6.

The two upper walls of the lower part form the seat 13 of the first stool 10 and the seat 14 of the second stool 11.

According to the embodiment of the invention shown in FIGS. 3 and 4, the seat 13 and seat 14 are located at different heights relative to the floor of the car, but can also be installed at the same height in accordance with another implementation method.

The surfaces of the seats 13 and 14 are generally arranged horizontally at different heights relative to the floor of the car. Each of these surfaces does not have an obvious violation of the continuity of the plane of inclination. In other words, stiffeners are provided on each of these surfaces, i.e. in general, it is flat.

According to the embodiment shown in FIGS. 3 and 4, the surfaces of the seats 13 and 14 are flat. Each of the seats 13 and 14 is connected to the lower, generally vertical wall 15 and 16, which contains a curved upper part. The lower vertical walls 15 and 16 are elongated in the transverse direction of the car 1.

Each of the surfaces of the seats 13 and 14, while remaining generally flat, has in some embodiments a concave or curved shape.

The casing 6 also includes an upper part 19, forming a design in the form of an inverted letter U. The upper part 19 is a block that includes the frames of the backrest 20 of the first stool 10 and the backrest 21 of the second stool 11.

In particular, the upper part 19 of the casing contains two transverse walls forming the legs of the letter U and elongated in the vertical direction from the seat 13 and, respectively, of the seat 14 to the upper wall 24 of the upper part 19 of the casing 6. The wall 24 forms the base of the frame in the form of the letter U.

Two transverse walls form the back 20 of the first stool 10 and the back 21 of the second stool 11. They are connected by means of a vertical wall 27, elongated as a whole in the longitudinal direction.

Each of the transverse walls 20 and 21 is elongated in the transverse direction to the maximum possible portion of the width of the seats 13 and 14.

Each of the backs 20 and 21 contains a rounded-concave surface. Each of these surfaces does not have an obvious violation of the continuity of the plane of inclination. In other words, each of these surfaces does not contain stiffeners, i.e. in general, it is flat.

According to the method of carrying out the invention depicted in FIGS. 3 and 4, the upper 19 and lower 12 parts of the casing 6 form a single structure. In this case, the casing 6 is formed by one piece. An option may be considered when the casing contains a certain number of blocks, for example, two separate parts, forming, respectively, the upper part 19 and the lower part 12 of the casing 6.

The casing 6 forms a rigid frame. It is, for example, a single design, the constituent elements of which are made of polyester plastic. Each part is molded so that it can give it a simple curved shape, such as, for example, according to the implementation method depicted in figures 3 and 4.

According to the implementation method shown in FIGS. 3 and 4, passengers are placed directly on the frames of the banquettes 10, 11 formed by the casing 6. In particular, the passengers sit directly on the surface of the seats 13, 14 and lean directly against the surface of the backs 29, 21.

It is clear that the even shape of the surfaces of the seats and backs of banquets allows you to place a different number of passengers on one bench, while the comfortable state of passengers improves when the number of passengers occupying a banquet is insignificant. Indeed, a single passenger sitting on a bench can occupy the entire width of a bench without being forced to limit the space formed by the stiffener and designed to accommodate one passenger.

According to a second embodiment of the invention shown in FIGS. 5 and 6, the comfort structure 30 (shown by a dashed line) is located on the surface 40 of the structure of the bench 10. The surface 40 is formed by the surface of the seat 13 and the surface of the back 20.

The surface 40, according to the method of carrying out the invention depicted in FIGS. 5 and 6, is not even and contains a violation of the continuity of the inclination of the plane between the backs 20, 21 and the adjacent seats 13, 14.

The comfort structure 30 is also located on the surface 41 of the banquet 11. The surface 41 is formed by the surface of the seat 14 and the surface of the backrest 21.

Comfort structures 30 adhere to surfaces 40, 41.

In particular, according to the embodiment of FIGS. 4 and 5, the comfort structure 30 comprises an integral comfort element of the seat 28 configured to be located on the surfaces of the seats 13 and 14. The comfort structure 30 also comprises an integral comfort element of the back 29 made with the ability to stick on the surfaces of the backs 20 and 21. Moreover, each component of the comfort of the seats 28 and backs 29 contains, for example, at least one stuffed seat cushion, elastically deformable, covered with esthetes Beautifully beautiful case. Components of comfort do not have a rigid structure.

The comfort structure is glued directly to the surfaces of the seat and backrest structures.

The thickness of the stuffed seat cushions forming the comfort elements is selected depending on the degree of comfort that the user needs. It does not depend on the shape of the casing.

According to the embodiment of the invention shown in FIGS. 5 and 6, the comfort components of the seats 28 and the backs 29 of a single structure are disconnected. In addition, the comfort element of the seat 29 of the chair 10 contains two separate pillows, including one pillow, which is located on the upper surface of the backrest 20, and one pillow, located on the lower part of the surface of the backrest 20.

Conversely, the comfort element of the seat 29 of the chair 11 contains one single pillow, which is located on the entire surface of the backrest 21.

An option may be considered when these two constituent elements form a single whole, for example, a single pillow, which is completely located on the surface 40, 41 of the chair 10, 11.

According to another embodiment, the comfort structure 30 comprises only one constituent comfort element of the seat 28 or the only constituent comfort element of the back 29.

According to the method of carrying out the invention depicted in FIGS. 5 and 6, the comfort structure 30 is the same for two seats that the bench 10 contains. In particular, the sole constituent comfort element of the seat 28 and the sole constituent comfort element 29 perform the functions of providing seat comfort and comfort backs of two seats of a banquet 10. A similar situation develops with a banquet 11.

Thus, each banquette can accommodate one or more people. When a single passenger occupies a double seat designed for two seats, the comfort of the latter will be higher than when he shares the banquet with another passenger. Indeed, between the seats, the elements of comfort do not make any distinction. One passenger, occupying a bench designed for two seats, thus enjoys all the comforts of a width provided for two people.

According to a third embodiment, as shown in FIGS. 7 and 8, a comfort structure 30 (shown by a dashed line) is provided for each seat of the seats 10 and 11. Thus, two comfort structures 30 are located side by side on the surface 40 of the banquet 10 and on the surface 41 of the banquet 11.

Thus, the flatness of the surfaces of the seats and backs of banquets allows you to easily change the width of the comfort elements of the seats and create a level of passenger comfort depending on user requests. Such adjustment does not require casting a new casing.

As shown in FIGS. 3-8, the comfort elements of the seat 28 are located on the entire surface of the seats 13 and 14 and capture part of the surfaces of the vertical walls 15 and 16 in such a way as to provide better comfort and aesthetic appearance of the chair.

In one embodiment, the comfort elements include a cutout that does not envelope the surface contours. For example, the comfort design does not bend around the longitudinal contours of the surface that it covers. Thus, the appearance of the seats easily changes, changing the shape of the comfort elements.

As shown in figure 3, aesthetic elements 31 are glued to the surface areas of the casing 6. These elements are not involved in creating the comfort of the seat or back.

Thus, it is easy to understand that the flatness of the surfaces of the seat and back of the bench allows you to bring the shape and thickness of the comfort elements into line with the level of comfort and aesthetic appearance that the user requires; however, the shape and thickness of these comfort elements does not depend on the reinforcement carried out in these walls and intended to accommodate comfort elements in them.
