[0054] FIG. 1 shows a door 10 comprising a fixed frame 12 that is partially shown. The door 10 comprises a first leaf 14a and a second leaf 14b. The leaves 14a, 14b can be slid towards one another in the direction of the arrows 16a, 16b in order to close the door 10.

[0055] The fixed frame 12 comprises a running rail 18, on which the carriages 20a, 20b, 20c, 20d can travel in order to move the leaves 14a, 14b. The leaves 14a, 14b are supported on the upper face by means of sliders 22a, 22b, 22c, 22d on the fixed frame 12. The carriages 20a-20d and the sliders 22a-22d can be actuated by a first connecting-rod assembly 24a on the first leaf 14a and by a second connecting-rod assembly 24b on the second leaf 14b, in order to move the leaves 14a, 14b outwards from the fixed frame 12 in the sliding position.

[0056] The connecting-rod assemblies 24a, 24b can each be actuated by a first handle 26a and a second handle 26b, respectively, as shown schematically and offset in FIG. 1. The first handle 26a is coupled to the first connecting-rod assembly 24a by a first mechanism 28a of the first connecting-rod assembly 24a. The second handle 26b is coupled to the second connecting-rod assembly 24b by a second mechanism 28b of the second connecting-rod assembly 24b.

[0057] The leaves 14a, 14b are securely connected by end-face connections, which each comprise a locking striker 30a, 30b, 30c, 30d, a locking cam 32a, 32b, 32c, 32d engaging in each of the locking strikers (see also the view of the locking striker 30a and the locking cam 32a in the upper views in FIG. 6a-6d).

[0058] FIG. 1 shows the handles 26a, 26b with solid lines in the blocking position. The sliding position of the handles 26a, 26b is indicated by dashed lines. The handles 26a, 26b preferably have just two switch positions, such that the leaves 14a, 14b can be directly transferred from the blocking position into the sliding position, avoiding a tilted position or gap-opening position.

[0059] The leaves 14a, 14b can thus be actuated by a fitting assembly 34. The leaves 14a, 14b, which abut one another at the end faces when closed, i.e. are locked to one another, have to be closed in a certain sequence. The first leaf 14a, also called the passive leaf, has to be closed before the second leaf 14b, also called the active leaf, in order to prevent collisions in the region of the end faces of the leaves 14a, 14b or the locking strikers 30a-30d with the locking cams 32a-32d. This closing sequence is enforced by a means 36 for securing against operating errors, which is described in the following.

[0060] FIG. 2a shows a detail of the door 10 and the fitting assembly 34 in the region of the means 36 for securing against operating errors. The means 36 for securing against operating errors has a first projection 38 and a second projection 40. The first projection 38 is movably arranged on the first leaf 14a. In this case, the first projection 38 is preferably securely arranged on, in particular riveted to, the first connecting-rod assembly 24a. The first connecting-rod assembly 24a can be arranged under a first cover rail 42a. The first projection 38 may be in the form of a bolt. The second projection 40 is preferably securely arranged on the second leaf 14b, in particular on a second cover rail 42b and/or directly on the leaf profile. The second projection 40 may be cuboid.

[0061] FIG. 2b shows the door 10 according to FIG. 2a, the leaves 14a, 14b having been moved towards one another from their position in FIG. 2a. The first connecting-rod assembly 14a is in the blocking position. The first projection 38 can pass by the second projection 40 in this blocking position. In the present embodiment, the first projection 38 can pass by the second projection 40 vertically above the second projection 40.

[0062] It can also be seen from FIG. 2b that the fitting assembly 34 comprises a means 44 for securing against raising. The means 44 for securing against raising comprises a third projection 46. The third projection 46 may be cuboid. The third projection 46 can be securely arranged on the first leaf 14a. Here, the third projection 46 can in particular be fastened to the first cover rail 42a and/or directly to the leaf profile. The third projection 46 prevents the first leaf 14a from lifting up, since the third projection 46 abuts the second projection 40 in this case. The third projection 46 is therefore preferably arranged under the second projection 40. Particularly preferably, the second projection is arranged, in the vertical direction, between the first projection 38 and the third projection 46.

[0063] FIG. 2c shows the door 10 according to FIG. 2a, with the first connecting-rod assembly 24a not being in the blocking position, but in the sliding position. In this sliding position, the first projection 38 is located vertically, at the level of the second projection 40, such that, when closing the leaves 14a, 14b, the two projections 38, 40 meet at the end faces thereof, at least in part and in particular completely. This prevents the leaves 14a, 14b from closing any further as long as the first leaf 14a is not in the blocking position. Damage to the fitting assembly 34 owing to this incorrect actuation is prevented in this way.

[0064] In the sliding position of the first leaf 14a shown in FIG. 2c, the first connecting-rod assembly 24a can be actuated in order to transfer the first projection 38 into the blocking position, shown in FIG. 2b. By contrast, the first connecting-rod assembly 24a cannot be actuated in the blocking position shown in FIG. 2b with the leaves 14a, 14b pushed together, and therefore incorrect actuation of the first connecting-rod assembly 24a is eliminated.

[0065] The first projection 38 and/or the second projection 40 can comprise a buffer 48 in order to dampen the impact of the first projection 38 on the second projection 40.

[0066] FIG. 3 shows another embodiment of a door 10 comprising a fitting assembly 34. The embodiment according to FIG. 3 corresponds to the embodiment described in FIGS. 1 to 2c. However, the third projection 46 is spaced apart from the second projection 40. Furthermore, the fitting assembly 34 comprises a fourth projection 50, which the third projection 46 abuts in an upward direction when the door 10 is closed, in order to form a means 44 for securing against raising for the first leaf 14a.

[0067] FIG. 4 shows another embodiment of a door 10 comprising a fitting assembly 34. The embodiment according to FIG. 4 corresponds to the embodiment described in FIGS. 1 to 2c. However, the third projection 46 is mounted on the fixed frame 12. Part of the fitting assembly 34, in particular a slider, in this case a slider 22a, vertically abuts the third projection 46 when the first leaf 14a lifts up and forms a means 44 for securing against raising as a result.

[0068] FIG. 5 is a schematic view of the door 10 shown in FIGS. 1 to 2c. It is clear from FIG. 5 that the leaves 14a, 14b are arranged in the C version (Schema C). Preferably, the leaves 14a, 14b are arranged to run outwards in this case, as shown in FIG. 5. The action of sliding the two leaves 14a, 14b towards one another is indicated in FIG. 5 by the arrows 16a, 16b in the main plane of the door 10. FIG. 5 shows each of the leaves 14a, 14b in the blocking position. In order to open the leaves 14a, 14b, said leaves are moved outwards, preferably perpendicularly to the main plane of the door 10. The possible positions of the leaves 14a, 14b in this case are shown in FIGS. 6a to 6d.

[0069] FIG. 6a shows the door 10 with leaves 14a, 14b that are abutting one another at the end faces. The leaves 14a, 14b are both locked to one another in the blocking position, as can be seen from the locking cam 32a engaging in the locking striker 30a. The first projection 38 has passed by the second projection 40 such that the leaves 14a, 14b could approach one another.

[0070] FIG. 6b shows the door 10 according to FIG. 6a, with both the first leaf 14a and the second leaf 14b being in the sliding position. By contrast with the view according to FIG. 6a, a mushroom head 52 of the locking cam 32a does not engage behind a protrusion 54 of the locking striker 30a. The locking striker 30a is preferably arranged on the first leaf 14a such that the locking cam 32a can only move into and out of the locking striker 30a in the vertical direction. The first projection 38 abuts the second projection 40 at the end face, such that the leaves 14a, 14b cannot be moved further towards one another as long as the first leaf 14a is not in the blocking position.

[0071] FIG. 6c shows the door 10, with the first leaf 14a being in the blocking position and the second leaf 14b being in the sliding position. Since the first projection 38 can pass by the second projection 40, the second leaf 14b can be readily transferred into the blocking position.

[0072] FIG. 6d shows the door 10, with the first leaf 14a being in the sliding position and the second leaf 14b being in the blocking position. The first projection 38 abutting the second projection 40 prevents the leaves 14a, 14b from being slid together any further. As a result, any damage to a seal 56 arranged between the leaves 14a, 14b is also prevented.

[0073] When considering all figures of the drawings together, the invention relates in summary to a fitting assembly 34 and to a window or door 10 comprising a fitting assembly 34 of this kind. The fitting assembly 34 comprises a means 36 for securing against operating errors. The means 36 for securing against operating errors has a first projection 38, which can be moved relative to a second projection 40, in particular vertically, by means of a first connecting-rod assembly 24a. A buffer 48 may be provided between the end faces of the first projection 38 and the second projection 40. The first projection 38 may be cylindrical and/or the second projection 40 may extend in an elongate manner in the vertical direction. More preferably, the fitting assembly 34 may comprise a means 44 for securing against raising comprising a third projection 46, which prevents the first leaf 14a from lifting up. The fitting assembly 34 preferably comprises a plurality of carriages 20a-20d and a plurality of sliders 22a-22d, in order to move leaves 14a, 14b of the window or door 10 in the sliding position thereof in parallel with the main plane of the window or door 10. In the blocking position, by contrast, the leaves 14a, 14b may be pressed against a fixed frame 12 of the window or door 10 by the fitting assembly 34 comprising a plurality of carriages 20a-20d and a plurality of sliders 22a-22d, in order to reliably seal the window or door 10.
