Such a guide device has been disclosed, for example, by DE 202014104927. During the assembly of the door, it can still happen that the door leaf rests on the ground for a short period of time before pissing her off. In the case of door leaves, until now the metal guide runners protruded from the bottom and had to support the entire weight of the door when the door leaf was placed on the ground. Therefore, in the case of high door weights, it could happen that the guide runners are bent or the fastening screws are pulled out of the door leaf.

DE 102015 112004 A1 discloses a guide arrangement for a sliding door comprising a U-shaped guide means mountable on a sliding door, which can be moved in a mounted position along a guide rail . The guide means is movable from a mounting position, in which it is disengaged with the guide rail, towards the mounted position, the guide means being movable from the mounting position to a deflection position, in which the guide means is disposed completely above a lower side of the sliding door.

WO 2012/045510 A1 discloses a sliding door roller guide with a guide roller pivotally attached to a support. The guide roller is placed in a lever system connected to the support, which is spring-loaded into a functional final position and/or is held positively.

The present invention is based on the object of specifying an improved guide device. In particular, the guide runners should be prevented from bending when a door leaf is set down on the ground.

This object is solved by a guide device having the features of claim 1. The dependent claims relate to advantageous further developments of the guide device according to the invention. Preferably, the first guide fitting and/or the second guide fitting are formed of plastic. The two guide fittings have the following advantages in particular:

- The guide fittings can be made of metal or, which is preferred, of a plastic injection molded part. In the latter case, no rework is required.

- The guide fittings can be pre-mounted on the door leaf by hand, ie without tools. - The guide fittings are swiveling in their unlocked position, i.e. no part protrudes downwards during assembly of the door leaf.

- Quick and easy locking of the door leaves by means of the guide fittings in a lower guide rail built in front or below.

- Guide fittings can be used on existing front and under built guide rails.

- No change of the plinth/body constructions is necessary.
