Description

The claimed technical solution relates to transport engineering, in particular to the design of the ceilings of the premises of a passenger car.

The passenger car ceiling is known (RF patent No. 51578, B61D 17/18, claimed. September 26, 2005, published February 27, 2006 Bull. No. 6), comprising a support frame, gripping elements connected by spring loops, a composite panel, parts of which are mounted on the support frame with the possibility of rotation, fasteners.

In this design, the presence of a frame frame complicates and complicates the design of the ceiling.

The closest technical solution (adopted as a prototype) is the ceiling of the vestibule of an electric train car (certificate of the Russian Federation No. 28473 for utility model, B61D 17/18, declared December 10, 2002, published March 27, 2003 Bull. No. 9), containing mounted in the form of a single module on the power brackets, a frame frame on which ceiling panels are mounted using swivel brackets and locking mechanisms - inclined, horizontal with fixtures and horizontal technological, with each horizontal technological and inclined ceiling panels with one on the other side, at least two swivel lock mechanisms are installed, and on the other hand, at least two swivel brackets.

In the known device, the presence of a frame frame in the form of a single module makes the construction of the ceiling heavier, and the absence of adjusting elements in the frame complicates the installation of the ceiling in the room when changing within the tolerance of the dimensions of the room. In addition, the known design cannot be used for rooms of a car with a limited height dimension, in which the ventilation duct extends downward beyond the plane of the ceiling panels due to the limited dimensions of the ceiling space, for example, in double-deck cars.

The objective of the proposal is to facilitate the construction of the ceiling, simplify its installation and use the car with a limited height for indoor use, for example, in double-decker cars.

For this, the ceiling of the passenger carriage contains ceiling panels, locking mechanisms, swivel joints. New is that it is made stepped with the arrangement of panels in two levels and is equipped with load-bearing beams placed between panels of different levels, and compensators mounted on opposite walls of the room; each compensator consists of a support element associated with each of the said beams by means of an adjusting device, and at least two lateral limiters, located at an angle to the corresponding carrier beam and in contact with them by the inner surface of the leading edge, the lower level panel is connected with one of load-bearing beams by means of swivel joints, and on the other by means of locking mechanisms, and is in contact with the outer surface of said supporting element, top-level panel at one end with Uniform with bearing beams by fasteners, and an opposite end fixed to the car body elements.

In addition, the adjustment device is made in the form of longitudinal grooves in the end part of the carrier beam and the fixing elements.

The technical result is expressed in the following.

The execution of the ceiling step with the arrangement of panels in two levels allows you to use it for rooms with a limited size in height, for example, in double-decker cars.

The presence of load-bearing beams placed between panels of different levels, the connection of the lower-level panel with one of the load-bearing beams by means of swivel joints, and with the other through locking mechanisms, and the connection of one ends of the upper-level panels with the load-bearing beams by means of fasteners, and the opposite ends are fixed the elements of the car body exclude the need for a single support frame, which facilitates the design of the ceiling as a whole.

The presence of compensators mounted on opposite walls of the room, each of which consists of a support element connected to each of the said beams by means of an adjusting device, as well as the presence of at least two lateral limiters located at an angle to the corresponding supporting beam and the inner surface in contact with them the leading edge, and the implementation of the lower level panel in contact with the outer surface of the supporting element provide fastening of the supporting beams with the possibility of adjustable their position when changing within the permissible deviations of the dimensions (width) of the room, which simplifies the installation of the ceiling on the car.

The accompanying drawings depict:

figure 5 is a cross section GG in figure 1;

figure 6 is a cross section DD in figure 1.

The ceiling of the passenger carriage contains ceiling panels 1, 2, 3, locking mechanisms 4, swivel joints 5. It is made in a stepped form with panels 1, 2, 3 arranged at two levels and equipped with load-bearing beams 6, 7 located between panels 1, 2 , 3 different levels. Also, the ceiling is equipped with compensators 8, 9, mounted on opposite walls 10, 11 of the room. Each compensator 8, 9 consists of a support element 12 connected to each of the beams 6, 7 by means of an adjusting device 13, and at least two lateral limiters 14, located at an angle to the corresponding carrier beam 6, 7 and internal contacting with them the surface of the leading edge 15. The adjusting device 13 is made in the form of longitudinal grooves 16 in the end part of the carrier beam 6, 7 and the fixing elements 17. The fixing elements 17 can be made in the form of screw fastening (figure 5) or rivet (not shown).

The lower level panel 1 is connected to one of the supporting beams 6 by means of pivot hinges 5, and on the other 7 by means of locking mechanisms 4, and is in contact with the outer surface 18 of the supporting element 12. The upper level panels 2 and 3 are connected at one end to the supporting beams 6 and 7 by means of fasteners 19, and with the opposite end fixed to the elements 20 and 21 of the car body, respectively.

The gaps 22 between the panel 2, 3 and the walls of the premises 10, 11 are blocked by visors 23 mounted on the walls 10, 11 of the panel 2, 3.

The assembly of the ceiling is as follows.

Compensators 8, 9 are fixed on the walls of the premises 10, 11, respectively. Visors 23 are also fixed on the walls 10, 11. Next, the supporting beams 6, 7 are mounted on the supporting elements 12 by means of an adjusting device 13. In this case, the longitudinal position of the supporting beams 6, 7 depending on the actual distance between the walls 10, 11 of the room is regulated by a longitudinal groove 16 and fixed by the fixing element 17. In the transverse direction, each carrier beam 6, 7 is pressed against the inner side of the leading edge 15 of the respective side stops 14. Then, the panels 2, 3 are connected to the beams 6, 7, respectively, by cr fastening elements 19, and their opposite ends are fixed on the elements of the car body 20, 21, respectively. After that, the panel of the lower level 1 is connected to the supporting beam 6 with compression to the outer surface 18 of the supporting element 12 by means of pivot joints 5 and to the supporting beam 7 by means of locking mechanisms 4.
