Door unit for rail vehicles

摘要

A door unit for rail vehicles includes one or two sliding doors, means for supporting and guiding each sliding door between a closed position and an open position, and means for controlling the movement of each door between a closed position and an open position. The supporting, guiding and controlling means are carried on a support unit which defines an independent module with the doors, assembled prior to being mounted on the vehicle structure. The support unit includes at least one frame connectable to the vehicle structure and supporting each door, and the respective guiding and controlling means. The frame includes an upper cross-member, a lower cross-member and two uprights connecting these cross-members between them, in such a way to form a perimeter frame that defines a doorway, and which surrounds the four sides of the door or doors, when they are in the closed position.

1. Door unit for rail vehicles, comprising:
at least one sliding door, means for supporting and guiding said at least one sliding door between a closed position and an open position, means for controlling the movement of said at least one door between a closed position and an open position, wherein said means for supporting and guiding, and said controlling means are carried on a support unit which defines an independent module with said at least one door, assembled before being mounted on the structure of the vehicle, at least one frame connectable to the vehicle structure and carrying said at least one door, and respective guiding and controlling means, said at least one frame comprising an upper cross-member, a lower cross-member and two uprights connecting these cross-members between them, so as to form a perimeter frame that defines a doorway and which surrounds the four sides of said at least one door when it is in a closed position, said at least one frame comprising:
a first perimeter frame, rigidly connectable to the vehicle structure, anda second perimeter frame supporting said means for supporting and guiding said at least one door and said controlling means of said at least one door,the second perimeter frame being supported by said first frame so as to be displaceable with respect to it in a horizontal direction orthogonal to the general plane of the door, between a retracted position and an advanced position with respect to the side of the vehicle, in order to reduce or eliminate any gap in the horizontal direction between the vehicle floor and the station platform, actuating means carried by said first frame, to control the horizontal movement of said second frame with respect to said first frame between the retracted position and the advanced position, and in said closed position said at least one door only cooperating with parts of said at least one perimeter frame to achieve the closure of the compartment door.
