Abstract

A door device for the interior of a passenger transport vehicle, and a passenger transport vehicle having at least one door device. The device includes a double-leaf sliding door with a first door leaf and a second door leaf in one plane. The door device has an upper guide for the first door leaf and an upper guide for the second door leaf. The guides are parallel with one another, and at least the upper guide for the first door leaf is offset with respect to the plane of the first and the second door leaf.

First claim

The invention claimed is:

1. A door device for an interior of a passenger transport vehicle, the door device comprising:
a double-leaf sliding door having a first door leaf and a second door leaf disposed in a common plane;
an upper guide for said first door leaf and an upper guide for said second door leaf;
said upper guides being arranged parallel to one another;
said upper guides being arranged on mutually different sides of said common plane of said first and second door leaves; and
at least said upper guide for said first door leaf being arranged offset with respect to said common plane of said first and second door leaves.

2. The door device according to claim 1 , wherein each of said upper guides comprises at least one guide rail and at least one sliding or running body guided along said at least one guide rail, and wherein each of said door leaves is connected to a respective one of said sliding or running bodies guided along a respective one of said guide rails.

3. The door device according to claim 2 , wherein:
said sliding or running body of said upper guide for said first door leaf is arranged in a direction of a closing movement of said first door leaf from an open position into a closed position at least partially ahead of said first door leaf; and/or
said sliding or running body of said upper guide for said second door leaf is arranged in a direction of a closing movement of said second door leaf from an open position into a closed position at least partially ahead of said second door leaf.

4. The door device according to claim 1 , wherein said upper guides span a horizontal plane and said common plane of said first and second door leaves intersects the horizontal plane spanned by said upper guides centrally between said upper guides.

5. The door device according to claim 1 , which comprises at least one arm between said first door leaf and said upper guide for said first door leaf and at least one arm between said second door leaf and said upper guide for said second door leaf, each said at least one arm bridging a spacing between said door leaf and the respective said upper guide.

6. The door device according to claim 1 , wherein said upper guide for said first door leaf and said upper guide for said second door leaf are of equal length.

7. The door device according to claim 1 , comprising a gear mechanism connecting said first and second door leaves to one another and causing said first and second door leaves to move in opposing directions relative to one another.

8. The door device according to claim 1 ,
comprising a traction drive with a belt or a chain, said belt or said chain having driver elements connected to, or to be connected to, said first and second door leaves, respectively.

9. A door device for an interior of a passenger transport vehicle, the door device comprising:
a double-leaf sliding door having a first door leaf and a second door leaf disposed in a common plane;
an upper guide for said first door leaf and an upper guide for said second door leaf, said upper guides being arranged parallel to one another, and at least said upper guide for said first door leaf being arranged offset with respect to said common plane of said first and second door leaves; and
a traction drive with a belt or a chain, said belt or said chain having driver elements connected to, or to be connected to, said first and second door leaves, respectively;
wherein said traction drive is at least partially arranged between said upper guides.

10. The door device according to claim 8 , wherein said traction drive includes deflection rollers for said belt or said chain, said deflection rollers having axes located in said common plane of said first and second door leaves.

11. The door device according to claim 8 , further comprising a door drive configured to displace said first and second door leaves by force actuation.

12. A passenger transport vehicle, comprising:
a door device in an interior of the vehicle, the door device including:
a double-leaf sliding door having a first door leaf and a second door leaf disposed in a common plane;
an upper guide for said first door leaf and an upper guide for said second door leaf;
said upper guides being arranged parallel to one another;
at least said upper guide for said first door leaf being arranged offset with respect to said common plane of said first and second door leaves; and
wherein said upper guide for said first door leaf and said upper guide for said second door leaf are arranged between a ceiling of the vehicle and a roof of the vehicle.

13. The vehicle according to claim 12 , configured as a double-decker rail vehicle having an upper deck, and wherein said door device is disposed in the upper deck of the double-decker rail vehicle.
