Abstract

A railroad vehicle where an air conditioner can be installed in an upper part of a roof thereof includes a roof structure having an opening, and a low roof main body having a recessed part provided in the opening, and recessed in a cross section, the air conditioner being able to be placed on the recessed part, and an edge part of the low roof main body which is continuously formed from the low roof main body and joined to the roof structure. The low roof main body and the edge part of the low roof main body are made of plastic.

First claim

What is claimed is:

1. A railroad vehicle comprising:
a roof structure having an air conditioner installation opening for receiving an air conditioner; and
a low roof main body provided in the opening, the low roof main body including:
a recessed part recessed into the roof structure in a vertical direction of the railroad vehicle away from an upper surface of the roof structure, the recessed part being a lowest portion of the low roof main body in the vertical direction;
a placing part configured to receive the air conditioner on an upper surface of the placing part, the placing part being flat and horizontal in a width direction of the railroad vehicle, the placing part being connected to the recessed part and extending outward away from the recessed part in the width direction of the railroad vehicle, the placing part being disposed above the recessed part in the vertical direction, and the recessed part extending downward in the vertical direction from the placing part; and
an edge part formed integrally as one piece with the low roof main body and joined to the roof structure, the edge part being located above the placing part in the vertical direction, the edge part defining an outer edge of the low roof main body, the placing part being disposed between the edge part and the recessed part in the vertical direction, the placing part extending between the edge part and the recessed part, wherein

the low roof main body and the edge part of the low roof main body are made of plastic.

2. The railroad vehicle of claim 1 , wherein
the roof structure has a metal frame extending toward the opening, and
the frame, the roof structure, and the edge part of the low roof main body are joined together.

3. The railroad vehicle of claim 1 , wherein
the roof structure has a metal frame extending toward the opening, and
the frame and the edge part of the low roof main body are joined together with rivets or adhesives.

4. The railroad vehicle of claim 1 , wherein
the roof structure has a metal frame extending toward the opening,
a lower surface of the edge part of the low roof main body and an upper surface of one end part of the frame are joined together, and
the upper surface of the roof structure and a lower surface of another end part of the frame are joined together.

5. The railroad vehicle of claim 1 , wherein
the roof structure has a metal frame extending toward the opening,
one end part of the frame is joined to the edge part of the low roof main body, and
another end part of the frame is joined to the roof structure by low-heat-input welding.

6. The railroad vehicle of claim 1 , wherein a bottom part of the recessed part comprises a sandwich structure having two face plates made of reinforced plastic and a core member provided between the face plates.

7. The railroad vehicle of claim 6 , wherein the core member is a honeycomb structure or the core member is made of foamed resin.

8. The railroad vehicle of claim 1 , wherein a bottom part of the recessed part is formed in a corrugated plate structure made of reinforced plastic, the bottom part forming alternate ridge portions and valley portions that extend in a vehicle width direction.

9. The railroad vehicle of claim 1 , further comprising a cover member covering an upper part of the low roof main body,
wherein a lower surface of an end part of the cover member is placed via a sealing member onto an upper surface of an end part of the edge part of the low roof main body on a side of the edge part closer to the recessed part.

10. The railroad vehicle of claim 1 , wherein at least the low roof main body and the edge part of the low roof main body are integrally formed.

11. The railroad vehicle of claim 1 , wherein
the bottom portion is disposed at a bottom of the recessed part in the vertical direction, and
the placing part is disposed above the bottom part and below the edge part.

12. The railroad vehicle of claim 1 , further comprising an air conditioner having a leg part at an edge of the air conditioner, the air conditioner being installed in the recess part via the leg part, wherein
a position of an upper surface of the installed air conditioner is lower than the edge part of the low roof main body.

13. A railroad vehicle comprising:
a roof structure having an air conditioner installation opening for receiving an air conditioner;
a low roof main body provided in the opening, the low roof main body including:
a recessed part recessed into the roof structure in a vertical direction away from an upper surface of the roof structure, the recessed part including a placing part configured to receive the air conditioner on an upper surface of the placing part, the placing part being flat and horizontal in a width direction of the railroad vehicle, and
an edge part formed integrally as one piece with the low roof main body and joined to the roof structure, and being located above the placing part, the edge part defining an outer edge of the low roof main body, the placing part being disposed between the edge part and a bottom portion of the recessed part in the vertical direction, wherein

the low roof main body and the edge part of the low roof main body are made of plastic,
the edge part of the low roof main body has a stepped part that includes the placing part, and
the placing part has a protrusion that extends upwardly in the vertical direction, a draining hole being provided between the protrusion and the edge part of the low roof main body.

14. The railroad vehicle of claim 13 , wherein the protrusion is an attachment base of the air conditioner.
