RU2340492C1 - Passenger car ceiling lining - Google Patents

Abstract

FIELD: transportation, construction.

SUBSTANCE: passenger car ceiling lining contains horizontal (1), sloping (2) panels and brackets (3) attached by their end shelves (4) and (5) to ceiling and body elements. Lower part of slope panel is connected to bracket slope shelf (8). At the top of slope panel on its inner side connecting elements with L-shaped part (12) projecting over panel edge are attached. Ceiling element (7) is made in the form of channel bar in which cut-out (16) is made to pass the said L-shaped part resting by its edge on wall internal surface of the said channel bar.

EFFECT: reduction of mounting clearance between slope and horizontal panels and car ceiling appearance improvement, lowering of dismantling works labour consumption.

Description

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

The well-known "Wagon Ceiling" (Japan Patent No. 3658900, B61D 17/12, decl. 12/18/1996, publ. 06/08/2005), containing an element divided into two sections, one of which includes a Central panel, and the other is lateral. These panels are bolted and nuts to the carriages mounted on the rail with the possibility of movement. In this case, the side panel with the bracket starts over the edge of the central panel.

In this design, the hook engagement occurs blindly, there is no suspension, therefore, it is necessary to maintain the side panel in weight until it is fixed. The central panel mount is covered by the side panel. When performing urgent installation work, the central panel can only be opened with the side panel removed and the luggage rack removed, which is inconvenient.

The closest technical solution (adopted as a prototype) is “The inner lining of the ceiling of a passenger carriage” (ed. Certificate of the USSR No. 1255491, B61D 17/18, declared 05.03.1985, published 07.09.1986, Bull. No. 33 ), containing horizontal, inclined panels and brackets attached with their end shelves to the ceiling and body elements, to the inclined shelf of which the lower part of the inclined panel is attached. In the upper part of the inclined panel on its inner side, connecting elements with a L-shaped part are fixed, interacting with the hooks of the brackets.

In this cladding design, for the installation and dismantling of inclined panels, a large gap is required between the inclined and horizontal panels, which impairs the appearance of the ceiling, and when dismantling, an additional operation is required to lift the inclined panel up and keep it on weight.

The objective of the proposal is to reduce the installation gap between the inclined and horizontal panels and improve the appearance of the ceiling, as well as reduce the complexity of the dismantling work.

For this, the passenger car ceiling lining contains horizontal, inclined panels and brackets attached with their end shelves to the ceiling and body elements, to the inclined shelf of which the lower part of the inclined panel is attached, in the upper part of which are connected the connecting elements with the L-shaped part. What is new is that the said L-shaped part protrudes above the edge of the panel, and the ceiling element is made in the form of a channel, in which a cut is made for the passage of the indicated L-shaped part, resting its edge on the inner surface of the wall of the said channel.

In addition, the inner surface of the channel wall is supported by linings to support the L-shaped part of the connecting element.

The technical result is as follows.

The execution of the L-shaped part protruding above the edge of the panel, and the ceiling element in the form of a channel, in which a cut is made for the passage of the specified L-shaped part, resting its edge on the inner wall surface of the said channel, which allows to reduce the gap between the horizontal and inclined panels, which improves the appearance of the ceiling, and also excludes during dismantling the operation of lifting the panel up and keeping it on weight, which reduces the complexity of dismantling.

The accompanying drawings depict:

figure 1 - lining the ceiling, General view;

figure 2 is a section aa in figure 1;

figure 3 - node B in figure 2.

The ceiling lining of the passenger carriage contains horizontal 1, inclined panels 2 and brackets 3. Each bracket 3 is attached with its end shelves 4 and 5, respectively, to the elements 6 of the car body and the elements 7 of the ceiling. The lower part of the inclined panel 2 is attached to the inclined shelf 8 of the brackets 3 with screws 9. In the upper part of the inclined panel 2, on its inner side 10, connecting elements 11 are fixed with the L-shaped part 12 (Fig. 3), which protrudes above the edge 13 of the panel 2. The ceiling element 7 is made in the form of a channel, in the wall 14 and the shelf 15 of which a cutout 16 is made for the passage of the L-shaped part 12, resting its edge 17 on the inner surface 18 of the channel 14 of the channel 7. The inner surface 18 of the wall 14 of the channel 7 can be supported by linings 19 for support T-shaped portion 12 of the connecting member 11.

Assembly is as follows.

After fixing the elements 7 of the ceiling, horizontal panels 1 are installed and the carriage equipment is mounted. The bracket 3 is inserted with the upper part into the cutout 16 of the channel 7, rests part of its upper horizontal shelf 20 on the inner surface 18 of the wall 14 of the channel 7 or the lining 19 and is fastened by the end shelf 5 to the inner surface 21 of the shelf 22 of the channel 7 with bolts 23. The lower part of the bracket 3 is fastened end shelf 4 to the body element 6 with screws 24. After that, the inclined panel 2 with the L-shaped part 12 is inserted into the cutout 16 of the channel 7, rests with its edge 17 on the inner surface 18 of the wall 14 of the channel 7 or the lining 19. Then the panel 2 is fastened with screws 9 to shelf 8 of bracket 3.

If necessary, a routine inspection of the carriage equipment located behind the panel 2, the latter is released from the bottom mount (unscrew the screws 9), while it turns and takes a plumb position. If necessary, the panel 2 is shifted to the cutout 16 and, having removed it, inspect.

Claims (2)

1. The lining of the ceiling of a passenger carriage, containing horizontal, inclined panels and brackets attached with their end shelves to the ceiling and body elements, to the inclined shelf of which the lower part of the inclined panel is attached, in the upper part of which are connected the connecting elements with the L-shaped part characterized in that the said L-shaped part protrudes above the edge of the panel, and the ceiling element is made in the form of a channel, in which a cut is made for the passage of the specified L-shaped part, supporting I with its edge on the inner wall surface of said channel bars. 2. The lining according to claim 1, characterized in that the inner surface of the channel wall is supported by linings for supporting the L-shaped part of the connecting element.
