DETAILED DESCRIPTION OF THE DRAWINGS

(9) Turning to FIG. 1, a roller carriage 10 includes two structural components, the roller module 20 and the basic body 30. In this case, both structural components, namely the roller module 20 and the basic body 30 include a plurality of individual parts. Said individual parts will be briefly explained in the following.

(10) Here, the roller module 20 is equipped with a bearing device 26 having 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, a rotary motion is performed at the manipulation interface 36, which motion simultaneously produces a linear translatory motion 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 relates to converting the adjusting movement into a fine-tuning movement along the direction of gravity SKR.

(11) 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 the height adjusting device 70. Furthermore, a mounting device 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 clamping fixing between the basic body 30 and the roller module 20.

(12) Here, a further mounting device 90 includes 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 a mounting device, 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, in order to affix the sliding door 110 in a clamping manner.

(13) All mounting devices 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.

(14) 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 aligned 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.

(15) 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.

(16) FIG. 6 shows how basically two structural components can be distinguished from each other. In this case, the components are the roller module 20 and the basic body 30. Here, rollers 26a, which are configured in this case from plastic material, of the bearing device 26 are visible at the roller module 20. Also, the transferring portions 21 are visible, which are able to reach full contact with the appropriate counter-transferring portions 31 of the basic body 30. Moreover, the basic body includes two U-shaped glass clamps 39, in which the sliding door 110 can be disposed in a clamped attachment.

(17) If the two structural components of the basic body 30 and the roller module 20 are attached to each other, an inventive material pairing is the result. The two materials, namely the first material of the roller module 20 and the second material of the basic body 30 have sound technical properties in this case, as illustrated in an abstract way in FIG. 7. In this case, the corresponding conductibility of structure-borne sound is illustrated on the y-axis, whereas a corresponding distinction in different directions, respectively of different types of structure-borne sound is represented on the x-axis. For example the angle of propagation of the structure-borne sound can be plotted on the x-axis. Also, a frequency spectrum or an amplitude spectrum can be plotted on the x-axis. It is well visible, that the two basic sound conducting ranges I and II can be clearly distinguished from each other. The corresponding resulting curves for the first material and the second material, namely for the roller module 20 and the basic body 30, are in this case oriented to be complementary, respectively essentially complementary. In the event a corresponding structure-borne sound from said sound conducting range I is generated in the sound conducting range I in the roller module 20 or is picked-up therein, said generated or picked-up structure-borne sound is conducted farther. Said structure-borne sound is transferred via the transferring portion 21 and the counter-transferring portion 31 onto the basic body 30. However, in exactly said sound conducting range I, the basic body is equipped with a very poor sound conductance and thereby with a dampening property. In the second material of the basic body 30, the structure-borne sound is now conducted very slowly or not at all, and its amplitude is dampened in this way. The overall amount of sound, which the system of the roller carriage emits, is thereby reduced. Thus, FIGS. 6 and 7 show in a very illustrative way, in which way the complementary dampening property of the two different materials of roller module 20 and basic body 30 provide the dampening effect within the system.
