Description

[0045] In the drawings:

[0046] FIG. 1 is a schematic illustration of a door in the form of a sliding door with a roller carriage arrangement;

[0047] FIG. 2a is a side view of another roller carriage arrangement;

[0048] FIG. 2b is a plan view of the roller carriage arrangement according to FIG. 2a;

[0049] FIG. 2c is a perspective view of a portion of the roller carriage arrangement according to FIGS. 2a and 2b.

[0050] FIG. 1 shows a door 10 having a fixed frame 12 and a leaf 14 which can be moved relative to the fixed frame 12. A handle 16 is arranged on the leaf 14. In a first handle position 18a, the door 10 is closed and the leaf 14 is firmly in abutment with the fixed frame 12. In a second handle position 18b, the leaf 14 can be released from the fixed frame 12 and can be displaced in the direction of an arrow 20 parallel with the fixed frame 12. In a third handle position 18c, the leaf 14 may be able to be tilted.

[0051] In order to move the leaf 14 relative to the fixed frame 12 in the direction of the arrow 20, the leaf 14 is supported at the lower side thereof by means of a roller carriage arrangement 22 on a sliding rail 24 of the door 10. The roller carriage arrangement 22 has a first roller carriage 26 and a second roller carriage 28, which are connected by means of a first coupling rod 30 of the roller carriage arrangement 22. In order to achieve a reliable support of the weight of the leaf 14 on the sliding rail 24, the first roller carriage 26 has three rollers 32a, 32b, 32c. As a result of the distribution of the leaf load over the three rollers 32a-c the rollers 32a-c are subjected to only a low level of wear. The roller carriages 26, 28 are connected to the leaf 14 in each case by means of a deployment arm (not shown).

[0052] FIG. 2a is a side view of another roller carriage arrangement 22. FIG. 2a shows that the roller carriage arrangement 22 has a first retention member in the form of a first profile rail 34a, a second retention member in the form of a second profile rail 34b and a third retention member in the form of a third profile rail 34c for fixedly connecting the roller carriage arrangement 22 to a leaf 14 (see FIG. 1). The profile rails 34a-c are constructed separately from each other.

[0053] FIG. 2b is a plan view of the roller carriage arrangement 22 according to FIG. 2a. FIG. 2b shows that the roller carriage arrangement 22 has a first roller carriage 26 whose deployment arms 36a, 36b are each connected to one of the profile rails 34a, 34b. The two deployment arms 36a, 36b are at the other end pivotably arranged on a roller carriage housing 38 of the first roller carriage 26.

[0054] The roller carriage arrangement 22 has a second roller carriage 28 and a third roller carriage 40. The second roller carriage 28 is connected to the third profile rail 34c via a deployment arm 36c, the third roller carriage 40 is connected to the third profile rail 34c via a deployment arm 36d. The guiding of the deployment arm 36d is carried out by means of a control arm 42 of the third roller carriage 40. The control arm 42 is at one end pivotably arranged on the deployment arm 36d. At the other end, the control arm 42 is guided in a slotted member 44 of the third roller carriage 40. The control arm 42 can thereby engage in the shown released position of the roller carriage arrangement 22 and can thereby retain the deployment arm 36d in a released state.

[0055] The connection of the roller carriages 26, 28, 40 is carried out by means of coupling rods 46a, 46b, 46c. A damper 48 is arranged between the coupling rods 46a, 46b. The damper 48 has a damper arm 50 which is pivotably arranged on the deployment arm 36a. The damper 48 damps both the pivoting-in movement of the deployment arm 36b and the pivoting-out movement of the deployment arm 36b. A uniform inward and outward pivoting of the leaf 14 which can be secured to the profile rails 34a-c is thereby achieved (see FIG. 1).

[0056] FIG. 2c shows the roller carriage arrangement 22 in the region of the first roller carriage 26. In FIG. 2c, rollers 32a, 32b, 32c which are arranged on the single-component roller carriage housing 38 can be seen.

[0057] When viewing all the Figures of the drawings together, the invention relates in summary to a roller carriage arrangement 22 for a window or a door 10 in the form of a sliding window or a sliding door. A leaf 14 of the window or the door 10 can be released by the roller carriage arrangement 22 from a fixed frame 12 and can be displaced parallel with the main frame plane of the fixed frame 12. The roller carriage arrangement 22 has a first roller carriage 26 which has at least three rollers 32a-c on a roller carriage housing 38. Alternatively or additionally, the first roller carriage 26 has at least two deployment arms 36a, b on the roller carriage housing 38.
