Vehicle door provided with a joint
View Patent ↗The invention relates to a railway vehicle including a body defining a wall in which an access passage is embodied, at least one closing sliding door, a sealing joint carried by the door and applicable to the wall when said door in a closed position. Said wall includes a panel provided with a generally cylindrical envelop and a seat which is protruded with respect to said panel and defines a bearing surface for supporting the joint only when the door is in the closed position, wherein said bearing surface of a supporting element extends along a profile substantially identical to the joint profile and said joint profile extends transversely with respect to the door displacement direction.
1. A railroad vehicle comprising:
a body delimiting a wall having an access passage;
at least one sliding closing door, slidable in a direction of movement parallel to the wall between a closed passage position and a retracted position, the door being retracted along the wall away from the passage in the retracted position;
a sealing joint carried by a support element belonging to the door and pressable, when the door is in the closed position, onto a joint bearing element formed by the wall to provide a seal, the support element including a panel; and
the support element including a seat projecting from the panel, the seat forming a bearing surface on which the sealing joint bears only when the door is in the closed position, the bearing surface of the support element extending along a profile similar to a joint profile, and the joint profile extending transversely to the direction of movement of the door;
wherein the door can be moved only by a translational movement with respect to the wall, the movement being parallel to a plane of the panel.
2. The vehicle as recited in claim 1 wherein the seat delimits a frame forming a door frame applied and fixed to the panel of the wall.
3. A railroad vehicle comprising:
a body delimiting a wall having an access passage;
at least one sliding closing door, slidable in a direction of movement parallel to the wall between a closed passage position and a retracted position, the door being retracted along the wall away from the passage in the retracted position;
a sealing joint carried by a support element belonging to the door and pressable, when the door is in the closed position, onto a joint bearing element formed by the wall to provide a seal, the support element including a panel; and
the support element including a seat projecting from the panel, the seat forming a bearing surface on which the sealing joint bears only when the door is in the closed position, the bearing surface of the support element extending along a profile similar to a joint profile, and the joint profile extending transversely to the direction of movement of the door;
wherein the sealing joint has a polygonal outer profile, and none of the sides of the polygon formed by the sealing joint extends parallel to the direction of movement.
4. The vehicle as recited in claim 1 wherein the bearing surface has a perpendicular surface facing the outside of the passage.
5. The vehicle as recited in claim 1 wherein the seat is bordered, on the side corresponding to the central part of the door, with a gutter for draining runoff water, transverse to the direction of movement D.
6. The vehicle as recited in claim 1 wherein when the door is outside its closed position, the sealing joint is separated from the main panel of the support element.
7. The vehicle as recited in claim 1 wherein the body has a step along a lower edge of the passage, and the door is designed to cover the step in the closed position.
8. A railroad vehicle comprising:
a body delimiting a wall having an access passage;
at least one sliding closing door, slidable in a direction of movement parallel to the wall between a closed passage position and a retracted position, the door being retracted along the wall away from the passage in the retracted position;
a sealing joint carried by a support element belonging to the wall and pressable, when the door is in the closed position, onto a joint bearing element formed by the door to provide a seal, the support element including a panel; and
the support element including a seat projecting from the panel, the seat forming a bearing surface on which the sealing joint bears only when the door is in the closed position, the bearing surface of the support element extending along a profile similar to a joint profile, and the joint profile extending transversely to the direction of movement of the door;
wherein the door can be moved only by a translational movement with respect to the wall, the movement being parallel to a plane of the panel.
