The invention relates to a locking device for a sliding leaf of a sliding wing system according to the preamble of claim 1.

In the design of sliding sash systems several sliding panels are arranged parallel to each other displaceable on a bottom rail. To achieve an open position of a sliding wall while the sliding sash can be positioned one behind the other; To close the sliding wall, the sliding sash can be moved one behind the other. For this purpose, the sliding leaves are provided on the bottom side with rollers, with which they are movable on mutually parallel catwalks of the bottom rail. On the ceiling side, the sliding sashes are guided in a ceiling rail. To fix the position of a sliding wing this is regularly provided with a locking device. This locking device comprises a locking hook, which is pivotally mounted in a housing and can be hooked into a arranged on a fixed object or on a sliding wall eyelet. In order to prevent unauthorized moving a sash, it is also known to arrange a blocking device which blocks the sliding sash against the bottom rail or against the ceiling rail. Locking devices for sliding sash are for example from the US R E24 443E as well as the DE 11 31 549 B known.

A disadvantage of the previously known solutions is that several devices are required for locking to secure a side wing. In addition, it may happen that the interaction with the bottom rail or the ceiling rail is subject to wear.

The invention aims to remedy this situation. The invention has for its object to provide a locking device for a sliding sash of a sliding sash system, which allows a safeguard against unauthorized movement of the sash without interaction with the bottom rail or the ceiling rail. According to the invention, this object is solved by the features of the characterizing part of claim 1.

With the invention, a locking device for a sliding leaf of a sash wing system is provided which allows a safeguard against unauthorized movement of the sash without interaction with the bottom rail or the ceiling rail. By arranged in the housing means for fixing the locking hook a pivoting of the hook is prevented, so that it can not be moved out of a fixing lug. In this case, the operating lever is connected to a slotted guide, which is designed such that the operating lever can be locked in two defined rotational positions. As a result, two defined positions "unlocking" / "locking positions" allows, which counteracted, for example, inadvertent locking a sliding sash. The slotted guide is arranged in the locking hook, wherein the operating lever is connected to a rotary cam, which engages in the slotted guide. In this case, the locking hook is advantageously biased by a spring against the rotary cam, whereby a reliable interaction between rotary cam and slide guide is guaranteed.

In a further development of the invention, the means for fixing the locking hook comprise a pivotally mounted locking lever, which can be applied in the locking position of the locking hook on a arranged on the locking hook boom, whereby the determination of the locking hook is effected. As a result, a simple and reliable determination of the locking hook is achieved.

In an embodiment of the invention, the locking lever is part of a lock arranged in the housing. This makes it possible to close the fixing of the locking hook by means of a key.

In a further development of the invention, the locking hook is pivotally mounted on an axis which is arranged offset to the axis of rotation of the operating lever in the housing. As a result, a good leverage between the operating lever and locking hook is achieved.

In a further embodiment of the invention, an emergency device for actuating the operating lever is arranged on its side facing away from the operating lever on the housing. This makes it possible to open a sliding sash when accidentally closing it from the outside.

In a further development of the invention, the emergency device is formed by a contour element connected to the axis of the operating lever, which can be operated via a corresponding contour tool. In this case, the contour element advantageously has a slot or an internal polygon for receiving a slot or polygonal tool. The slot contour is therefore particularly suitable because it can also be operated by a coin, for example.

In another embodiment of the invention, the housing is designed such that it can be introduced into the frame profile of a sliding leaf, wherein at least one roller is arranged on the housing. As a result, the device is simultaneously used as a carriage for the sliding leaf, whereby the component depth is further reduced.

In a preferred embodiment of the invention, the roller is arranged on a pivotally mounted in the housing roller receptacle, which is connected to an adjusting element, via which the roller receptacle is pivotable, whereby a height adjustment of the support roller can be achieved. As a result, an adjustment of the side wing is possible. The pivotally mounted in the housing roller receptacle by which the height adjustment is effected, it requires only a small space.

In another embodiment of the invention, the adjusting element is formed by a screw which can be screwed against the roller holder, whereby a pivoting of the roller holder can be achieved. As a result, a finely adjustable height adjustment is possible.

Advantageously, a cap is formed on the housing, which has a passage opening for the locking hook. This allows simultaneous closure of the opening of the frame profile after insertion of the housing. Subsequent closure of the frame profile via a separate cap is not required.

In an additional embodiment of the invention, at least one side projecting driver is integrally formed on the cap. By such an integrated driver easy sliding of the sliding sash is made possible in a sliding sash system.
