  Here, the block element 84 can be opened on the upper running part 14 by means of a rotary handle 96 (as shown in FIG. 9a) and is arranged on the engagement element 98 and the lock bar 80 on that side of the block element. The positive lock fitting between the ribs 100 can be released.

In the position shown in FIG. 9 a, the lock bar 80 of the upper traveling unit 14 is at a position where the upper end of the guide plate 97 of the upper traveling unit 14 is higher than the lower end of the upper guide rail 10 when viewed in the displacement direction 22. It is in the upper position.
As a result, the guide plate 97 cannot be inserted into the guide slot 58 of the upper guide rail 10.

However, this is possible at the position of the lock bar 80 of the upper travel part 14 in relation to the holder 78 of the upper travel part 14 as shown in FIG.
In the mounted position, the lock bar 80 is moved downward relative to the force of the spring 102, thereby changing the distance 124 between the lock bar 80 and the sheet metal part 89 to a larger distance 126.
In the mounting position, the guide plate 97 of the upper running part 14 is here positioned below the guide slot 58 of the upper guide rail 10 when viewed in the displacement direction 22 and thus slides when viewed in the displacement direction 22. The door 4 can be placed under the upper guide rail 10 by turning it around the lower guide rail 8.
The lock bar 80 can be pulled to this attachment position, for example, by pulling on the handle section 108.

When the guide plate 97 of the upper running part 14 is arranged below the guide slot 58 of the upper guide rail 10, the lock bar 80 of the upper running part 14 can be pushed by the spring 102 in the displacement direction 22, and thus the upper running part The guide plate 97 of the part 14 can be introduced into the guide slot 58 of the upper guide rail 10.
As a result, the sliding door is locked in the guide rails 8, 10 to be seen at an angle with respect to the guiding direction 16 and can no longer fall off the rail.

The blocking element 84 can then be closed until the rotating handle 96 abuts the protrusion 101 in the circumferential direction.
As a result, the positive lock fit between the engagement element 98 and the rib 100 disposed on the lock bar 80 is partially closed. Therefore, the lock bar 80 can be fixed in the locked position.

  In FIG. 10, the engagement element 98 and the rib 100 are shown in detail, which engage during rotation of the block element 84, thus preventing the sheet metal part 40 from moving relative to the lock bar 80. .

The adjusting screw 28 can be used particularly advantageously to set the height of the sliding door 4.
Initially, the block element 84 is released on the upper running part 14 by turning the rotary handle 96.
Thereafter, a desired height adjustment of the slide door 4 can be performed by the adjustment screw 28 on the lower traveling unit 12.
At the same time, the upper runner 14 automatically adjusts itself before the block element 84 is again moved to the locked position.
