[0031] FIG. 6 is an additional partial exploded view of the Detail II of FIG. 1;

[0032] FIG. 7 is an isometric view of an additional embodiment of a displacement arrangement;

[0033] FIG. 8 is a sectional view in the Area VIII according to FIG. 7 with the displacement arrangement mounted; and

[0034] FIG. 9 is a sectional view in the Area IX according to FIG. 7 with the displacement arrangement mounted.

[0035] FIG. 1 shows a displacement arrangement 10 having an actuating mechanism 12 in the shape of a circumferential drive rod fitting, which can be operated via an actuating handle 14. The actuating mechanism 12 is mounted on a window or a door shown in FIGS. 4 and 5 and extends along the fold circumferential direction 16. The fold circumferential direction 16 extends in the primary plane 18 (only indicated in FIG. 1) of the window or the door. In the embodiment shown, the displacement arrangement 10 has two positions a, b having a roller arrangement 20a, 20b and two positions c, d having a support arrangement 22a, 22b, wherein the roller arrangements 20a, 20b and the support arrangements 22a, 22b are each displaceable transversely to the fold circumferential direction 16.

[0036] FIG. 2 shows a part of the components of the Section II according to FIG. 1. It is recognizable that the actuating mechanism 12 has a pin-shaped first control projection 24a which engages a first control slot 26a which is formed in the shape of a first control slot. The first control slot 26a is at least partially formed obliquely to the fold circumferential direction 16. If the actuating mechanism 12 is relocated in the fold circumferential direction 16, the roller arrangement 20a is relocated vertically to the fold circumferential direction 16. The first control slot 26a is formed in a control part 28.

[0037] The roller arrangement 20a has at least one roller 30a, 30b. In addition, the roller arrangement 20a in this case has a support roller 32. The support roller 32 has an outer diameter which is larger than the width of the remaining roller arrangement 20a. This means that transverse forces on the roller arrangement 20a can be avoided by supporting the support roller 32.

[0038] FIG. 3 shows a representation of the Detail III according to FIG. 1. The support arrangement 22a also has a support roller 32 which is arranged around a vertical rotational axis. Analogous to the construction according to FIG. 2, the displacement arrangement 10 in the area of the Detail III has a control part 28 with a first control slot (not visible) in which a first control projection 24a engages. Furthermore, the displacement arrangement 10 has a guide part 34 which is not shown in the displacement arrangement 10 according to FIG. 2. The guide part 34 is fixedly mounted on the sash/leaf 40 (see FIGS. 4, 5). The first control projection 24a is mounted on a not shown first guide slot in the guide part 28 to reduce the friction during the operation of the actuating mechanism 12 in fold circumferential direction 16. The first control projection 24a engages through the guide part 34 and engages into the control part 28.

[0039] FIG. 4 shows a view from the closure side of a window or door 36 with a fixed frame 38 and a sash/leaf 40. The actuating mechanism 12 is mounted on the sash/leaf 40. This is supported by the roller arrangement 20a on a running rail 42. There is a gap 44 between the sash/leaf 40 and the fixed frame 38. The sash/leaf 40 therefore does not bear against a circumferential seal 46 of the fixed frame 38.

[0040] The support roller 32 bears against a guide 48 of the fixed frame 38 formed as a vertical web. In the position shown, the sash/leaf 40 can be displaced relative to the fixed frame 38, wherein the support roller 32 can support itself or roll on the guide 48. In the upper area of the window or the door 36, the fixed frame 38 also has a guide 48, which here is formed groove-like. The support roller 32 (see also FIG. 3) is guided in the guide 48.

[0041] FIG. 5 shows the window or the door 36 after operating the actuating mechanism 12. By the actuation of the actuating mechanism 12 the roller arrangements (in FIG. 5 the roller arrangement 20a is visible) and the support arrangements (in FIG. 5 the support arrangement 22a is visible) are relocated. This means that the sash/leaf 40 approaches the fixed frame 38 so that the seal 46 is clamped and compressed between the sash/leaf 40 and the fixed frame 38.

[0042] FIG. 6 shows an additional detailed view of the displacement arrangement 10 according to Detail II of FIG. 1. FIG. 6 shows that the first control projection 24a has a cylindrical shape and is arranged on the actuating mechanism 12. The first control projection 24a has a first rolling bearing 50 and a second rolling bearing 52. The first rolling bearing 50 is used for the low-friction guide of the first control projection 24a in a first guide slot 54a of the guide part 34. The second rolling bearing 52 is used for the low-friction guide of the first control projection 24a in the first control slot 26a of the control part 28.

[0043] The first guide slot 54a is formed in the direction of the fold circumferential direction 16 or parallel to the fold circumferential direction 16, whereas the first guide slot 26a is formed at least partially transverse to the fold circumferential direction 16. The roller arrangement 20a is arranged on the control part 28. The displacement arrangement 10 in the area of the Detail III (see FIG. 3) is formed analogously to this, wherein the control part 28 has the support arrangement 22a (see FIG. 3) instead of the roller arrangement 20a.

[0044] The guide part 34 is fixedly, i.e. rigid and stationary, arranged on the sash/leaf 40 (see FIGS. 4, 5), and here it can be screwed on. As can be seen from FIG. 6, a guide 56 is provided between the guide part 34 and the control part 28, which allows only a limited movement of the control part 28 relative to the guide part 34 transverse to the fold circumferential direction 16. In this example, the guide 56 is in the shape of a dovetail guide.

[0045] FIG. 7 shows an additional example of a displacement arrangement 10. The displacement arrangement 10 has a first control projection 24a and a second control projection 24b. The control projections 24a, 24b are formed in the same way. Furthermore, both control projections 24a, 24b are equal to the first control projection 24a according to FIG. 6. Both control projections 24a, 24b are arranged on the actuating mechanism 12.

[0046] The first control projection 24a is led in a, here unilaterally open, first guide slot 54a. The second control projection 24b is led in a second guide slot 54b, which is also open here. Furthermore, the first control projection 24a engages in a first control slot 26a and the second control projection 24b engages in a second control slot 26b. When the displacement arrangement 10 is actuated, the first control projection 24a emerges from the slots 26a, 54a assigned to it. Shortly before this exit, the second control projection 24b enters the assigned slots 26b, 54b, so that a continuous guide of the control part 28 (see FIGS. 8, 9) is ensured. The embodiment described here is described analogously in DE 10 2014 220 837 B3, to which reference is made in full scope.

[0047] FIG. 8 shows a cross-section of the displacement arrangement 10 in the Area VIII (see FIG. 7). FIG. 8 shows the guide of the first rolling bearing 50 on the first guide part 34 and the guide of the second rolling bearing 52 on the control part 28. The horizontal clearance of the first control projection 24a in the guide part 34 and in the control part 28, which is composed of the distances A and B (indicated enlarged for clarity in FIG. 8), is less than 0.5 mm. Ideally, the clearance tends towards zero. The inner rings of the rolling bearings 50, 52 are spaced apart by a spacer ring 58.

[0048] FIG. 9 shows a cross-section of the displacement arrangement 10 in the Area IX (see FIG. 7). FIG. 9 shows that a supporting rolling bearing 60 is arranged between the control part 28 and the guide part 34. This means that even very heavy sashes/leafs 40 (see FIG. 4, 5) can be supported displaceable with low-friction.

[0049] Summarizing all the figures in the drawing, the invention relates to a displacement arrangement 10 for moving a sash/leaf 40 of a window or a door 36 transversely to the fixed frame 38 of the window or the door 36. The displacement arrangement 10 has a control part 28 for indirectly supporting the transverse movement, which is displaced relative to a guide part 34 which can be fixedly mounted on the sash/leaf 40 by means of an actuating device 12. A first control projection 24a is provided between control part 28 and actuating device 12, which engages in a first control slot 26a of the control part 28 and simultaneously in a first guide slot 54a of the guide part 34. The first control projection 24a has a first rolling bearing 50 for the bearing at the first guide slot 54a. In addition, the first control projection 24a can have a second rolling bearing 52 for supporting on the first control slot 26a. Alternatively or in addition, a supporting rolling bearing 60 can be provided between the guide part 34 and the control part 28. The displacement arrangement 10 makes it possible to generate a high contact pressure of the sash/leaf 40 against the fixed frame 38 with moderate operating forces and thus a good sealing of the window or the door 36. Furthermore, a very low-friction setting-out of even heavy sashes/leafs 40 is possible by means of the operation of the actuating device 12 by a user of the window or the door 36.
