DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0072] FIG. 1a shows a door 10 with a fixed frame 12 and a wing 14. The wing 14 is indicated by mountings. The wing 14 can be moved in the displacement direction 16 when it is no longer in sealing abutment against the fixed frame 12 but is placed away from the fixed frame 12. Both the displacement of the wing 14 in the displacement direction 16 and the movement of the wing 14 in the transverse direction 18 is made possible by at least one carriage arrangement, here two carriage arrangements, 20a, 20b.

[0073] The displacement of the carriage arrangements 20a, b in the displacement direction 16 takes place on a running rail 22. The running rail 22 lies in the main plane 24 of the fixed frame 12. The displacement of the wing 14 transversely to this main plane 24, i.e., in the transverse direction 18, takes place in a positively controlled manner by the actuation of a handle 26. The handle 26 is equipped with a mechanism 28 which translates the pivoting movement of the handle 26 into a linear movement of a driving bar 30.

[0074] The carriage arrangements 20a, b furthermore make it possible for a user to adjust the vertical position of the wing 14. The set vertical height remains unchanged during the usual opening and closing of the door 10.

[0075] The height settings of the two carriage arrangements 20a, b are preferably structurally identical.

[0076] FIG. 1b shows the carriage arrangement 20a with a driving bar arrangement 32 and a carriage 34. The driving bar arrangement 34 comprises the driving bar 30. The driving bar arrangement 34 can furthermore have a lipped rail 36.

[0077] The carriage 34 has a wing part 38 which can be fastened immovably on the wing 14 (see FIG. 1a) and a roller part 40 that is movable in the transverse direction 18 (see FIG. 1a). To produce this movement in the transverse direction 18, the driving bar 30 has a control projection 42. The control projection 42 can be guided through a slot 44 in the lipped rail 36. Furthermore, the control projection 42 can engage through a straight guide slot 46 of the wing part 38. The control projection 42 engages in a control slot 50 formed at least sectionally obliquely to the longitudinal axis 48 of the roller part 40. The wing part 38 can be supported on the roller part 40 by a first roller bearing guide 52a. Preferably, the wing part 38 is additionally supported on the roller part 40 by a second roller bearing guide 52b.

[0078] The carriage 34 furthermore comprises a running roller holder 54 with multiple rollers 56a,56b. The running rollers 56a, b are held on guide plates 60a, 60b via roller axles 58a, 58 b. Furthermore, a guide roller holder 62 with a guide roller 64 rotatably mounted on the guide roller holder 62 can be arranged on the guide plates 60a, b. The guide roller 64 guides the carriage 34 in the transverse direction 18 (see FIG. 1a).

[0079] The running roller holder 54 is mounted pivotably on a roller upper part 68 via a horizontally extending pendulum axle 66. The roller upper part 68 has a vertically extending slot 70 for receiving the pendulum axle 66.

[0080] The guide roller holder 62 is preferably held rigidly on the guide plates 60a, b, so that a pendulum movement of the running roller holder 54 about the pendulum axle 66 is carried out not only by the running rollers 56a, b but also by the guide roller 64. Such a pendulum movement occurs, for example, when the carriage 34 runs over an obstacle, in particular dirt, on the running rail 22 (see FIG. 1a) or when the running rail has unevennesses, in particular “hills and valleys.”

[0081] The carriage 34 comprises a height adjustment 72. The height adjustment 72 comprises at least one adjusting screw 74, here with a nut 76 and an adjusting element 78.

[0082] FIG. 1c shows the carriage arrangement 20a with the adjusting element 78 in the assembled state. As can be seen from FIG. 1c, the roller upper part 68 is arranged so as to be vertically immovable relative to the wing part 38. The roller upper part 68 is guided in the wing part 38 in the manner of a dovetail.

[0083] FIGS. 1d and 1e show a schematic sectional view of the carriage arrangement 20a. From a combination of FIGS. 1d and 1 e it can be seen that the adjusting element 78 comprises a first adjusting element bevel 80a, which is supported on the pendulum axle 66. A linear displacement of the adjusting element 78 with respect to the roller upper part 68 effected by the adjusting screw 74 causes a vertical adjustment of the running roller holder 54 relative to the roller upper part 68. A linear displacement of the adjusting element 78 effected by the adjusting screw 74 in particular causes a proportional vertical adjustment of the running roller holder 54 relative to the roller upper part 68. The adjusting screw 74 here does not directly abut the running roller holder 54, but rather the adjusting element 78, so that a pendulum movement of the running roller holder 54 takes place wear-free and uninfluenced by the adjusting screw 74.

[0084] FIG. 1f shows the roller upper part 68 with an adjusting screw guide 82. The roller upper part 68 can comprise a central guide projection 84 with the slot 70. The roller upper part 68 is preferably formed in one piece, in particular in the shape of a block. The roller upper part 68 can have an underside recess 86 for at least partially receiving the adjusting element 78.

[0085] FIG. 1g shows the adjusting element 78. It can be seen from FIG. 1g that the adjusting element 78, in addition to the first adjusting element bevel 80a, can have a second adjusting element bevel 80b. Both adjusting element bevels 80a, b are preferably supported on the pendulum axle 66 (see FIG. 1b).

[0086] FIG. 2a shows a further embodiment of a carriage arrangement 20a. The carriage arrangement 20a according to FIG. 2a corresponds to the carriage arrangement 20a previously described in FIGS. 1a to 1 g, except for the differences described below.

[0087] In addition to the first adjusting element bevel 80a and the second adjusting element bevel 80b, the adjusting element 78 has a third adjusting element bevel 80 and a fourth adjusting element bevel 80d. The adjusting element bevels 80a-d are supported on the roller upper part 68 (see FIG. 2e).

[0088] FIG. 2b shows the carriage arrangement 20a in the assembled state. It can be seen from FIG. 2b that the pendulum axle 66 is guided in a first guide slot 88a of the roller upper part 68. The first guide slot 88a does not serve for offloading weight from the roller upper part 68 onto the running roller holder 54, but exclusively for guiding the pendulum axle 66.

[0089] FIG. 2c shows the roller upper part 68 with a first upper part bevel 90a, a second upper part bevel 90b, a third upper part bevel 90c and a fourth upper part bevel 90d. The upper part bevels 90a-d are supported on respective adjusting element bevels 80a-d (see FIGS. 2a and 2d). FIG. 2c also shows in the upper roller part 68 a second guide slot 88b for receiving the pendulum axle 66 (see FIG. 2b). Moreover, the second guide slot 88b is not used for offloading weight from the roller upper part 68 onto the running roller holder 54 (see FIG. 2b), but exclusively for guiding the pendulum axle 66 (see FIG. 2b).

[0090] FIG. 2d shows the adjusting element 78 with the adjusting element bevels 80a-d. From FIG. 2d, it can also be seen that the adjusting element 78 has aligned receptacles 92a, 92b, here in the form of holes, for mounting the pendulum axle 66 (see FIG. 2b).

[0091] In a combination of FIGS. 2e and 2f the vertical adjustability of the carriage arrangement 20a can be seen. The adjusting element 78 is movable in a straight line relative to the roller upper part 68 by means of the adjusting screw 74. The adjusting element bevels 80b, d visible in FIGS. 2c and 2d are here supported on upper part bevels 90b, d.

[0092] Taking a combination of all figures of the drawing together, the invention relates in summary to a carriage 34 with a wing part 38 which can be fastened to a wing 14 and a roller part 40 which is displaceable on a running rail 22, wherein the wing part 38 is positively displaceable transversely to the running rail 22. The roller part 40 has a height-adjustable roller upper part 68. The vertical adjustability of the roller upper part 68 with respect to a running roller holder 54 of the roller part 40 is achieved by an adjusting element 78 displaceable by means of an adjusting screw 74. The adjusting element 78 is preferably supported with at least one adjusting element bevel 80a-d on a pendulum axle 66 of the running roller holder 54 and/or on an upper part bevel 90a-d of the roller upper part 68.
