## Abstract

A fitting assembly has a device for securing against operating errors that has a first protrusion which can be moved relative to a second protrusion by means of a first operating rod assembly. A buffer can be provided between the end sides of the first protrusion and the second protrusion. The first protrusion can be a cylinder and/or the second protrusion can extend in an elongated manner. The fitting assembly can have an anti-lifting device with a third protrusion which prevents a lifting of the first leaf. The fitting assembly has multiple carriages and multiple sliders in order to position leaves of the window or the door into their slide position in parallel with the main plane of the window or the door. In the blocking position, the leaves can be pressed against a fixed frame of the window or the door via the fitting assembly with multiple carriages and multiple sliders, in order to reliably seal the window or the door.

## Claims

### Claim 1

A fitting assembly (34) for two leaves (14a, 14b) of a window or door (10) that can be slid towards one another, the fitting assembly (34) comprising the following:
a) a first connecting-rod assembly (24a) for a first one of the leaves (14a), wherein the first connecting-rod assembly (24a) is configured to be moved into a sliding position, in which the first leaf (14a) can slide, and into a blocking position, in which the first leaf (14a) cannot slide;
b) a second connecting-rod assembly (24b) for a second one of the leaves (14b), wherein the second connecting-rod assembly (24b) is configured to be moved into a sliding position, in which the second leaf (14b) can slide, and into a blocking position, in which the second leaf (14b) cannot slide;
wherein
the fitting assembly (34) comprises a first projection (38) on the first connecting-rod assembly (24a) and the fitting assembly (34) comprises a second projection (40) that is configured to be arranged on the second leaf (14b), and wherein the first projection (38) is configured to pass by the second projection (40) when the leaves (14a, 14b) are slid towards one another in the blocking position of the first connecting-rod assembly (24a) and is configured to collide with the second projection when the leaves (14a, 14b) are slid towards one another in the sliding position of the first connecting rod assembly so that the first projection prevents the two leaves from being completely slid together until the first connecting rod assembly is moved to the blocking position.

### Claim 2 (depends on 1)

The fitting assembly according to claim 1, wherein the first projection (38) is bolt-shaped.

### Claim 3 (depends on 1)

The fitting assembly according to claim 1, wherein the second projection (40) is configured to be fixedly arranged on the second leaf (14b).

### Claim 4 (depends on 1)

The fitting assembly according to claim 1, wherein the first projection (38) and/or the second projection (40) comprises a buffer (48) on an end face thereof in order to dampen an impact of the first projection (38) on the second projection (40).

### Claim 5 (depends on 1)

The fitting assembly according to claim 1, wherein the fitting assembly (34) comprises a third projection (46), which is configured to be arranged on the first leaf (14a) or a fixed frame (12) in order to secure the first leaf (14a) against lifting up.

### Claim 6 (depends on 5)

The fitting assembly according to claim 5, wherein the third projection (46) engages under the second projection (40) when the leaves (14a, 14b) are closed.

### Claim 7 (depends on 1)

The fitting assembly according to claim 1, wherein the fitting assembly (34) comprises a locking cam (32a-32d) that is arranged on the second connecting-rod assembly (24b) and a locking striker (30a-30d) that is configured to be fixedly arranged on the first leaf (14a) for receiving the locking cam (32a-32d) at least in part.

### Claim 8 (depends on 7)

The fitting assembly according to claim 7, wherein the locking striker (30a-30d) comprises a protrusion (54) and the locking cam (32a-32d) comprises a mushroom head (52) for engaging under the protrusion (54) in the blocking position of the second connecting-rod assembly (24b).

### Claim 9 (depends on 1)

A window or a door (10) comprising a fixed frame (12), two leaves (14a, 14b) that can be slid towards one another and a fitting assembly (34) according to claim 1, the fitting assembly being mounted on the leaves (14a, 14b).

### Claim 10 (depends on 9)

The window or the door according to claim 9 wherein the second projection (40) is fixedly arranged on the second leaf (14b).

### Claim 11 (depends on 9)

The window or the door according to claim 9 wherein the third projection (46) is fixedly arranged on the first leaf (14a).

### Claim 12 (depends on 9)

The window or the door according to claim 9, wherein,
i) in the sliding position of the first connecting-rod assembly (24a), the first leaf (14a) can be moved further outwards from the fixed frame (12) than in the blocking position of the first connecting-rod assembly (24a) and
ii) in the sliding position of the second connecting-rod assembly (24b), the second leaf (14b) can be moved further outwards from the fixed frame (12) than in the blocking position of the second connecting-rod assembly (24b).

### Claim 13 (depends on 9)

The window or the door according to claim 9, wherein the fitting assembly (34) comprises a first handle (26a) coupled to the first connecting-rod assembly (24a) and a second handle (26b) coupled to the second connecting-rod assembly (24b).

### Claim 14 (depends on 13)

The window or the door according to claim 13, wherein the first handle (26a) comprises only two switch positions, the two switch positions consisting of a first switch position in which the first connecting-rod assembly (24a) is in the blocking position and a second switch position in which the first connecting-rod assembly (24a) is in the sliding position.

### Claim 15 (depends on 13)

The window or the door or according to claim 13, wherein the second handle (26b) comprises only two switch positions, the two switch positions consisting of a first switch position in which the second connecting-rod assembly (24b) is in the blocking position and a second switch position in which the second connecting-rod assembly (24b) is in the sliding position.
