## Abstract

A junction for neighboring car bodies of a track-bound vehicle has a first door guided within a first end wall of a first car body for closing a doorway of the first car body and a second door guided with an adjacent second end wall of the neighboring car body for closing a doorway in the neighboring car body. The first and the second end walls are spaced apart and delimit a space therebetween. The first and the second doors are guided at the first and the second end walls so as to be movable in opposite directions. At least one coupling element for coupling the first and the second doors extends through the first and the second end walls and the space therebetween. The first and the second doors have a substantially identical construction and substantially identical moving characteristics. The coupling element is preferably a cable and a sleeve enclosing the cable.

## Claims

### Claim 1

A junction for neighboring car bodies of a track-bound vehicle, said Junction comprising:
a first door guided within a first end wall of a first car body for closing a doorway of the first car body;
a second door guided within an adjacent second end wall of the neighboring car body for closing a doorway in the neighboring car body, wherein said first and said second end walls are spaced apart and delimit a space therebetween;
said first and said second doors guided at said first and said second end walls to be movable in opposite directions;
at least one coupling element for coupling said first and said second doors extending through said first and said second end walls and said space therebetween; and
said at least one coupling element comprised of a first component and a second component;
said first component connecting said first and second doors for transmitting forces between said first and second doors;
said second component enclosing said first component and connected to the first and the neighboring car bodies; and
wherein a displacement of said first and second doors relative to the first and neighboring car bodies results in a displacement of said first component relative to said second component.

### Claim 2 (depends on 1)

A junction according to claim 1, wherein said first and said second doors have a substantially identical construction and substantially identical moving characteristics.

### Claim 3 (depends on 1)

A junction according to claim 1, wherein said coupling element is comprised of a cable and a sleeve enclosing said cable.

### Claim 4 (depends on 3)

A junction according to claim 3, further comprising:
a first set of actuating members connected to said first door and a second set of actuating members connected to said second door;
supports fixedly connected to the car bodies, with each said doorway having a first said support arranged on one side and a second said support arranged on the other side;
wherein two said cables are provided, with a first one of said two cables positioned on said one side of said doorways of said first and said second doors and with a second one of said two cables positioned on said other side of said doorways of said first and second doors;
wherein each one of said two cables has a first and a second end, said first end connected to said first set of actuating members and said second end connected to said second set of actuating members, wherein said sleeve of said first cable extends between said supports on said one side of said doorways and said sleeve of said second cable extends between said supports on said other side of said doorways.

### Claim 5 (depends on 4)

A junction according to claim 4, further comprising a first bellows for enclosing said sleeve of said first cable in said space between said first and said second end walls and a second bellows for enclosing said sleeve of said second cable in said space between said first and said second end walls.

### Claim 6 (depends on 6)

A junction according to claim 6, wherein each one of said first and said second bellows comprises a sealing sleeve positioned at a center of said first and said second bellows between said first and second end walls, said sealing sleeve filling an annular space between said sleeves of said first and second cables and said first and second bellows.

### Claim 7 (depends on 3)

A junction according to claim 3, wherein:
said end walls have openings and sliding sleeves positioned in said openings;
said cables are guided through said sliding sleeves of said openings; and
said sliding sleeves have an inner diameter that is slightly greater than an outer diameter of said sleeves.

### Claim 8 (depends on 3)

A junction according to claim 3, wherein said cable is arranged in the shape of a coil in said space between said first and said second end walls and penetrates vertically displaced said first and said second end walls.
