[0034] A holding element according to a first embodiment example of the present invention will be described in the following with reference to FIGS. 1 to 5 c. [0035] As is shown in FIG. 1, a guide device has, for example, two guide elements which are constructed as cylindrical rods 6. A sliding door 1 is displaceably supported at the rods 6 by four running rollers 3. The running rollers 3 are fastened by means of punctiform fastening elements 5 to the sliding door 1. The sliding door 1 is constructed as a glass door and has through-openings through which the fastening elements 5 are inserted in order to fasten the running rollers 3. The fastening elements terminate flush with the outer top side of the pane of glass 1. [0036] As is shown in FIG. 1, the two rods 6 are arranged at the furniture body 2 in such a way that a first rod 6 is fastened to an upper area of the furniture body 2 and a second rod 6 is fastened to a lower area of the furniture body 2. The rods 6 are fastened to the furniture body 2 by means of holding elements 7. As can be seen particularly from FIG. 1, an adjustable stop 13 is provided at the upper rod 6 at its two lateral ends in order to limit the displacement path of the sliding door 1. The stop is fastened directly to the rod 6 and limits the displacement path of the running rollers 3 on the right- and left-hand sides. [0037] As is shown particularly in FIGS. 2a to 2 e and 3 a to 3 d, the holding element 7 comprises three parts, namely, a holding part 8 which has a male thread and a receiving area 9 for the rod 6 (see FIG. 3), a base part 10 which is fastened to the furniture body 2, and a lock nut 11. The base part 10 and the lock nut 11 are screwed to the male thread area of the holding part 8. The rod 6 is fixed in the receiving area 9 of the holding part 8 (see FIG. 2d) by a stud screw 12. In particular, the holding element 7 according to the invention enables a height adjustment of the rod 6 by screwing the holding part 8 into or out of the base part 10. The distance between the rod 6 and the furniture body 2 is changed in this way. The final position of the holding element 7 can then be secured by the lock nut 11. This makes it possible to align the rod in a simple manner particularly also after mounting. [0038] As is shown particularly in FIG. 1, the rods 6 are fastened to an upper area or lower area of the furniture body 2 by holding elements 7. This makes it possible for the sliding door 1 to be arranged at only a short distance from the open area of the furniture body 2. [0039] As can also be seen from FIGS. 2c and 3 c, the receiving area 9 of the holding part 8 for receiving the rod 6 is constructed in such a way that it has two arc-shaped arms which project out over a center axis of the rod 6. Therefore, the rod 6 can not be removed from the holding element 7 in upward or downward direction, but must always be guided out of the holding element 7 in direction of its longitudinal axis. [0040] Further, the distance of the sliding door 1 from the furniture body 2 can be changed in a simple manner by arranging washers between the fastening element 5 and the running rollers 3. [0041] [0041]FIGS. 2a to 2 e show the holding element 7 according to the invention in a first embodiment example in detail. As is shown in the drawings, the holding element 7 comprises the holding part 8, the base part 10 and the lock nut 11. As can be seen in the perspective view of FIG. 2a and the side view in FIG. 2c, a receiving area 9 is formed in the holding part 8 in particular for receiving the rod 6. The outer diameter of the rod 6 is somewhat smaller than the inner diameter of the receiving area 9. The receiving area 9 is formed as a partial circle which is open in axial direction X-X of the holding element 7. Since the partial circle of the receiving area 9 is greater than a half-circle, a rod 6 that is held by the receiving area 9 can not be removed in direction X-X. The rod must always be removed in its longitudinal axis, i.e., vertical to the axis X-X in direction Y-Y (see FIG. 2b). [0042] A stud screw 12 which is inserted into a threaded bore hole 14 formed in the receiving area 9 (see FIGS. 2d and 3 d) serves to secure a rod 6 held in the receiving area 9. The rod 6 can be clamped in the receiving area 9 against the wall of the receiving area by means of the stud screw 12, so that it can no longer be displaced in direction of its longitudinal axis Y-Y. [0043] The holding part 8 of the holding element 7 is shown again in detail in FIGS. 3a to 3 d. As is shown there, the holding part 8 has an area 20 which is provided with a thread. The assembly of the holding element according to the invention can be seen particularly form the exploded view in FIG. 2e. First, the lock nut 11 is screwed onto the area 20 of the holding part 8 provided with the thread. Next, a screw 19 is guided from the inside through the opening 17 of the base part 10. As is shown in FIG. 1, the base part can be secured to a furniture body 2 by this screw 19. The opening 17 is preferably formed as an elongated hole, so that an optimal orientation of the base part 10 at the furniture body 2 can be achieved. Subsequently, the holding part 8 provided with the screwed on lock nut 11 is screwed into the female thread 18 of the base part 10 (see FIG. 5c). The height of the holding element 7 can be adjusted in any manner desired. When the desired height is reached, the position can be secured by means of the lock nut 11. As is shown in FIGS. 4a, 4 c and 4 d, the lock nut 11 has two flattened areas 15 so that a tool can be applied easily. After the holding element 7 is mounted, the rod 6 is guided into the receiving area 9 and is fixed in the desired position by means of the stud screw 12. [0044] Accordingly, the invention can provide a simply constructed holding element for a guide device for sliding doors, which guide device is constructed in a simple and stable manner and makes possible a height adjustment of the holding element 7 in its axial direction X-X. It is noted that the holding part 8 can likewise be constructed with a through-hole in direction X-X, so that the screw 19 can be fixed at the furniture body through this through-hole. [0045] A holding element according to a second embodiment example of the present invention is described in the following with reference to FIGS. 6a to 7 d. Identical parts or parts having the same function are designated by the same reference numbers as in the first embodiment example. [0046] As can be seen particularly from FIGS. 7a to 7 d, the holding part 8 is formed with an annular receiving area 9 in the second embodiment example in contrast to the first embodiment example. In other words, the receiving area 9 is no longer shaped like a partial circle, but rather is formed completely circularly, so that it fully encloses a rod 6. The rod is fixed again by means of a stud screw 12 in the receiving area 9. Otherwise, the second embodiment example corresponds to the first embodiment example and reference is had to the description given for this first embodiment example. [0047] A holding element according to a third embodiment example of the present invention is described in FIGS. 8a to 9 c. Identical parts or parts having the same function are designated by the same reference numbers as in the first embodiment example. [0048] As is shown particularly in FIGS. 8b and 8 d, the holding part 8 in the third embodiment example is again formed with a partially circular receiving area 9 similar to the first embodiment example. In contrast to the first embodiment example, the receiving area 9 is arranged in such a way that the free area is not directed in the direction of the axis X-X, i.e., in longitudinal direction of the holding element, but rather is directed 90° vertical to the axis X-X. For this reason, the holding element 7 according to the third embodiment example is especially suitable for being arranged at the front sides of furniture bodies 2, so that a rod arranged in the receiving area 9 is supported from the sides as well as from below. Otherwise, the holding element 7 according to the third embodiment example corresponds to the holding element described in the embodiment examples described above, and further description can be dispensed with. [0049] A holding element according to a fourth embodiment example of the present invention is described in FIGS. 10 to 13. Identical parts or parts having the same function are designated by the same reference numbers as in the preceding embodiment examples. [0050] The holding part 21 shown in FIGS. 10 to 13 is characterized in that there is a holding part 8 having a receiving area 9 similar to the preceding embodiment examples. A union nut 22 which is supported at the holding part on one hand and is fastened to the holding part 8 by a retaining ring 27 so as to be rotatable on the other hand is provided at the holding part 8 so as to be directed in the direction of a base part 23. The union nut is shown in a separate view in FIG. 16. The union nut 22 is constructed in such a way that it has a continuous bore hole 31 which penetrates the union nut 22 along a short area and subsequently ends in an undercut 32 having a larger diameter. On the other side, a bore hole 33 with a thread 24 adjoins the undercut. The thread 24 is screwed onto the base part 23. [0051] The base part 23 is shown separately in FIGS. 14 and 15. Analogous to base part 10, base part 23 has a through-hole 17 for fastening the base part 23 to a furniture body. A bore hole with a female thread 26 adjoins bore hole 17. There is a thread 25 on the outer circumference of the base part 23 which is used for screwing on the union nut 22. [0052] For purposes of mounting, the base part 23 is connected to the furniture body by a screw 19 through the through-hole 17. In order to carry out a height adjustment of the rod 6 inserted into the receiving area 9, a lock screw 28 is screwed into the thread 26 in the base part 23. A height adjustment and therefore a stop for the holding part can be formed by this lock screw 28. When the height adjustment is carried out, the union nut 22 with the holding part 8 is screwed onto the base part 23. In so doing, the union nut 22 can be screwed onto the base part 23 until a base surface 34 of the holding part 8 comes into contact with the lock screw 28. At the same time, the union nut 22 is pulled against the retaining ring 27 of the holding part 8 through this position, which ensures that the holding part 8 is fastened to the base part 23 without play. [0053] One possibility for fixing the rod 6 in the receiving area 9 of the holding part consists in a stud screw 12 located laterally in the holding part 8 inside a threaded bore hole 14 or in an invisible fastening of the rod 9 by a stud screw 29 extending in axial direction of the holding part 21. In this case, the rod 9 would have to be carried out before fitting the union nut 22 on the base part 23. [0054] Further, as was made clear by FIG. 10, a collar 30 is located at the base part 23 for supporting at the furniture body and has the same diameter as the union nut 22. A slender, plain holding element 21 is produced in this way. [0055] The present invention is accordingly directed to a holding element 7, 21 for holding a guide rail 9 for sliding doors, particularly sliding glass doors, with a holding part 8 and a base part 10. The holding part 8 and the base part 10 are connected to one another in such a way that they are adjustable relative to one another in axial direction X-X of the holding element. The holding element 8 has a receiving area 9 for holding a guide rail 9. The base part 10 can be fastened to the furniture body 2, e.g., by means of a screw 19.
