The chassis 12 includes at least one, preferably a plurality of, running wheel(s) 18, and two or more running wheels 18 having a vertical rotational axis and/or two or more running wheels 18 having a horizontal rotational axis may be provided. The connecting portion 14 is configured to be pre-mounted to the furniture part 3b, and the pre-mounted connecting portion 14 can be connected to the carrier 13 by at least one fastening device 19. The fastening device 19 can have at least one bearing location 20 arranged on the carrier 13, and the bearing location 20 engages into a corresponding recess 21 of the connecting portion 14 in a mounting position. The at least one bearing location 20, in the mounting position, is arranged substantially at a same height than the chassis 12, whereby a low lateral tilting moment is introduced in the chassis 12. In the shown embodiment, two fastening devices 19, 19a are provided, the two fastening devices 19, 19a being vertically spaced from one another and by which the connecting portion 14 can be releasably connected to the carrier 13. For this purpose, the carrier 13 includes at least two bearing locations 20, 20a spaced from each other in a height direction, and each of the two bearing locations 20, 20a engage into recesses 21, 21a spaced from each other in a height direction. Accordingly, the bearing portion 17 pre-mounted to the furniture part 3b can be engaged with the two recesses 21, 21a into the two bearing locations 20, 20a of the carrier 13, whereby a very simple mounting (by engaging) and demounting (by lifting) of the connecting portion 14 relative to the carrier 13 can be brought about. The connecting portion 14, in the shown embodiment, includes a bearing portion 17 (which is to be fixed via the recesses 21, 21a to the bearing locations 20, 20a of the carrier 13), two fitting portions 15, 15a which are spaced from each other in a height direction and which are to be fixed to the furniture part 3b, and a hinge mechanism 16 for pivotally connecting the fitting portions 15, 15a relative to the bearing portion 17 about an axis which preferably extends vertically in the mounting position.
(14) FIG. 4 shows the guide carriage 8, and the connecting portion 14 is connected to the bearing locations 20, 20a of the carrier 13 via the recesses 21, 21a. By lifting the connecting portion 14 in relation to the carrier 13, a very simple demounting can be brought about, without additional securing means need to be released.
(15) FIG. 5 shows the guide carriage 8 in a perspective view, in which the connecting portion 14 with the fitting portions 15, 15a to be fixed to the furniture part 3b is mounted to the carrier 13. By a positioning device 23, the fitting portions 15, 15a of the connecting portion 14 can be positioned relative to the chassis 12 in at least one linear direction, in the present case in a height direction (H). In the shown figure, the positioning device 23 includes a threaded portion 24 which is in a threading engagement with a bearing block 25. The threaded section 24 is arranged so as to be rotatable on the bearing portion 17, however, undisplaceable in the axial direction. By an actuation of an actuating element 27 (for example with a tool receiving device), the threaded section 24 can be rotated, and the bearing block 25 (and therewith the fitting portions 15, 15a) can be adjusted in the height direction (H). For linearly guiding the bearing block 25, a guiding rod 26 is provided. The guiding rod 26 extends parallel to the threaded section 24, and the bearing block 25 can be freely displaced along the guiding rod 26 upon a rotational movement of the threaded section 24. By the positioning device 23, the furniture part 3b can be adjusted in the height direction (H) relative to the other furniture part 3a in the mounted condition.
(16) FIG. 6a shows the guide carriage 8 in a perspective view from the rear, in which further positioning devices 23a are provided by which the furniture part 3b to be connected to the fitting portions 15, 15a can be positioned in a lateral direction (X) in a relation to the other furniture part 3a. Each of the fitting portions 15a, 15a includes a sliding portion 28, and each of the sliding portions 28 are linearly displaceably supported in the lateral direction (X) relative to base portions 29. Each of the sliding portions 28 and the base portions 29 are frictionally connected to one another, and the sliding portions 28 are configured to be displaced relative to the base portions 29 by applying a force against a frictional resistance. Visible is also the hinge mechanism 16 for the pivotable support of the two fitting portions 15, 15a, and the hinge mechanism 16 includes at least two pivotable hinge levers 16a, 16b.
(17) FIG. 6b shows the guide carriage 8 in which the sliding portions 28 have been displaced relative to the base portions 29 by applying a force to the furniture part 3b in a lateral direction (X). This clearly emerges from a direct comparison of FIG. 6a with FIG. 6b.
(18) FIG. 7 shows the guide carriage 8 in an exploded view. Arranged or formed on the carrier 13 is the chassis 12 having at least one running wheel 18. The bearing portion 17 of the connecting portion 14 is configured to be fixed via the fastening devices 19, 19a having the recesses 21, 21a to the bearing locations 20, 20a of the carrier 13. The bearing block 25 is movably mounted on the bearing portion 17, and the bearing portion 25 is displaceable in the height direction (H) relative to the bearing portion 17 upon pivoting the actuating element 27, and the bearing block 25 is guided along the guide rod 26. The two hinge levers 16a, 16b of the hinge mechanism 16 are pivotally connected to the bearing block 25, and the hinge lever 16b is configured to be connected to a holding device 31. The two base portions 29 of the fitting portions 15, 15a are fixed to the holding device 31 via supporting discs 32 and by screws 33. Each of the sliding portions 28 of the fitting portions 15, 15a is frictionally connected to the base portions 29. In the shown embodiment, the frictional connection between the base portions 29 and the sliding portions 28 is effected by spring elements 30. Each of the spring elements 30 are configured as pre-stressed leaf springs which produce the frictional force between the base portions 29 and the sliding portions 29. The spring elements 30 are thereby operative between an upper side of the base portions 29 and an angled limb 28a of the sliding portions 28.
