DETAILED DESCRIPTION OF THE DRAWINGS

(13) An embodiment of a roller carriage 10 is illustrated in an isometric illustration in FIG. 1. Basically, said carriage includes two structural components. The components are, on the one hand, the roller module 20 and, on the other hand, the basic body 30. In this case, both structural components, namely the roller module 20 and the basic body 30 include a plurality of different individual parts. Said individual parts will be briefly explained in the following.

(14) Here, the roller module 20 is equipped with a bearing device 26. Said bearing device 26 is equipped in this case with two rollers 26a, which are supported to be rotatable at a basic body of the roller module 20. Said rollers 26a can be placed onto, respectively inserted into a roller running path 120, as can be clearly seen in FIG. 2 and FIG. 3. A part of a height adjusting device 70 is provided furthermore at the roller module 20. The detailed components of said height adjusting device 70 are in particular illustrated in the FIGS. 4 and 5. Thus, a first adjusting means 32 is provided, which by means of a manipulation interface 36 is able to perform an adjusting movement. As in this case the first adjusting means 32 is configured as a threaded bolt in an adjusting thread 32, a rotational movement is performed at the manipulation interface 36, which movement simultaneously produces a linear translational movement of the first adjusting means 32. Via a corresponding contacting portion 34, the first adjusting means 32 is in operative connection with a counter-contacting portion 24 of the second adjusting means 22 of the roller module 20. In this case, the explicit action of said adjusting device consists in converting the adjusting movement into a fine-tuning movement along the direction of gravity SKR.

(15) As can be seen in FIG. 1, the roller carriage 10 is equipped with a plurality of different mounting devices 90, which are able to provide different mounting functions. In this case, the already described fine-tuning function of the height of the sliding door 110 is provided by means of the mounting device 90 in the shape of a height adjusting device 70. Furthermore, a mounting device 90 in the shape of a securing device 50 is provided, which after completed fine-tuning of the height of the sliding door 110 provides a clamped fixing between the basic body 30 and the roller module 20.

(16) In this case, a further mounting device 90 consists in an accessory device 40, which is provided by means of a corresponding interface, and an affixed accessory module 300. Moreover, a lift-off protection device 60 is provided as a mounting device 90, which provides a lift-off protection against unwanted removal of the roller carriage 10 out of the position in which it is inserted into the roller running path 120. Furthermore, an attachment device 80 is provided as a glass clamp for a mounting device 90, in order to affix the sliding door 110 in a clamped manner.

(17) All mounting devices have in common that they include at least one mounting means 92, in order to be able to perform a corresponding mounting movement. Moreover, a manipulation interface is provided, intended to allow for performing exactly said mounting movement with the mounting means.

(18) As furthermore revealed in FIG. 1, the roller carriage 10 has different sides, namely the first side 12 and the second side 14. In this case with regard to their manipulation interface 96, all mounting devices are preferably oriented from the same side, namely the first side 12 opposite to the second side 14, on which the bearing device 26 is disposed. This arrangement offers a considerably simpler access.

(19) FIG. 2 reveals how a sliding door 110 is retained by means of two roller carriages 10 according to FIG. 1, and that said two roller carriages 10 are already inserted into the roller running path 120. In a lateral illustration according to FIG. 3, in particular the correlation of the rollers 26a with the roller running path 120 is well visible.

(20) In a lateral illustration, FIG. 6 shows the roller module 20 and here explicitly the lift-off protection device 60. Said lift-off protection device 60 is equipped with a lift-off protection means 62, which is supported to be rotatable in the roller module 20. The illustration according to FIG. 6 shows the lift-off protection means 62 and in particular the lift-off protection portion 62a in its protection position SP. At the same time, the arresting device 64 is seen as a pin-shaped extension, wherein just the arresting means 64a is visible from the back side. At the same time, in the area of the lift-off protection portion 62a, a surface portion 62b is visible, which includes a convex surface curvature, not visible here, in order to be able to compensate for corresponding manufacturing tolerances. In particular FIGS. 7 and 8 reveal details in this regard.

(21) Thus, FIGS. 7 and 8 show the two distinct positions, namely the protection position SP in FIG. 7, and the release position FP in FIG. 8.

(22) The lift-off protection means 62 is rotatable between said two positions. In the protection position SP, it can be seen, that a small gap exists between the surface portion 62b of the lift-off protection portion 62a and a corresponding housing walling, in this case the running rail 130. Said gap is so small that a lifting as far as to contacting the running rail 130 will not result in a removal out of the roller running path 120. The possible movement in the direction of gravity SKR upwards is in particular revealed in FIG. 3. The concave configuration of the rollers 26 allows for a lifting in the opposite direction to the direction of gravity SKR, and the retaining function is maintained due to the convex configuration of the roller running path 120. The gap, which is visible in FIG. 7, is likewise visible at the top of FIG. 3 with regard to the roller module 20. FIG. 8 illustrates now how, by means of a rotation of the lift-off protection means 62 about less than 90, the described gap will be considerably increased, such that the surface portion 62b of the lift-off protection portion 64 is disengaged and inserting or removing the roller carriage 10 out of the roller running path 120 is possible.

(23) FIGS. 9-11 show details with regard to the transposition in an embodiment with spring elements. In this case, a first spring element 66 as well as a second spring element 64c are provided, which are both together configured in their function as rotatably and axially acting screw springs. Said two spring elements 64c and 66 act in the following way. In FIG. 9 the lift-off protection device 60 is located in the active position, namely the lift-off protection means 62 is in the protection position SP. For providing a movement, a linear, respectively an axial movement along the axis of movement BA is now realized, in order to bring the arresting means 64a out of engagement from a corresponding arresting reception 64b. The end of said movement is shown in FIG. 10, in which the entire lift-off protection portion 62a is displaced to the left against the force of the spring, and the arresting means 64a is thereby exposed. A rotation about the axis of movement BA is now possible, until the lift-off protection portion 62a reaches the release position FP according to FIG. 11. If the associated force is now withdrawn, the entire lift-off protection means 62 moves again back, axially and linearly to the right along the axis of movement BA and the arresting means 64a engages in the arresting reception 64b, in order to guarantee the arresting function. Obviously, said procedure can be reversed in order to switch from the release position FP into the protection position SP.

(24) The above explanation of the embodiments describes the present disclosure based on examples. Individual features of the embodiments, as long as technically reasonable, can be combined independently of each other without leaving the scope of the present disclosure.
