The present invention relates to a functional unit of a fitting for a component, in particular for a window or a door, wherein the component has a window frame and a wing movable relative to the window frame, wherein the functional unit comprises:

• a basic body,
• a relative to this adjustable coupling element, wherein the base body is designed for attachment to the frame and the adjustable coupling element is coupled to the wing or coupled, or vice versa,
• a drive for motorized adjustment of the coupling element along a travel such that in the assembled state of the functional unit of the coupling element coupled to the wing is movable in the direction of the frame, and
• a control device for controlling the drive, which is designed to provide at least one safety function for an anti-jamming device.

Such functional units are known in various configurations intended for different purposes, such as for automatically opening and closing a sash, for automatically locking a closed sash or for automatically tilting or shutting down a sash. For example, functional units of the type specified above are used as fitting components of rotary fittings, tilting fittings and tilt and turn fittings for windows, doors, gates, flaps and the like.

The coupling of the coupling element with the wing is to be understood not only in the sense of a permanent or releasable attachment, but also in the sense of a pulling or pushing attack, wherein the coupling element entrains the wing. That is, the coupling can only be effective in one direction.

In motorized moving wings of components there is a fundamental risk of pinching limbs, whereas measures must be taken in general. This can be done, for example, that the driving force is limited to a safe level via the controller. The associated controller may provide one or more such security functions.

However, appropriate protective measures are opposed to a firm and reliable closing and / or holding the wing. As a result, in particular, the heat-insulating effect of the relevant device may be undesirably limited.

It is an object of the invention to enable more reliable closing and holding of motorized wings of components without compromising anti-jamming protection.

The object is achieved by a functional unit having the features of claim 1.

The control device of a functional unit according to the invention is designed to provide the at least one safety function only during a first portion of the travel, while deactivating during a subsequent second portion of the travel to provide a contact pressure for a sealing engagement between the wing and the frame.

When the safety function is deactivated, the drive can pull or push the wing unhindered and with the greatest possible force against the frame. When the sash is closed, the relevant window thus has improved tightness. An anti-trapping is still because the path of the wing, which corresponds to the first portion of the travel of the coupling element is hedged in the usual way via the drive control. The determination of the first and the second portion of the travel can take place in consideration of the mechanical implementation of the movement of the coupling element in the movement of the wing such that the Einklemmgefahr during that wing movement corresponding to the second portion of the travel of the coupling element is reduced or not at all consists,.

In particular, it can be provided that the coupling element between an open position, which corresponds to a away from the frame or a released wing, and a closed position, which corresponds to a fully closed wing, is adjustable, wherein the second portion of the travel is an end portion associated with the closed position , In this embodiment, therefore, the main part of the closing movement of the wing is protected by the safety function and only at the end of the closing process, the safety function is disabled. In this phase of the wing movement there is no risk of entrapment because the wing is already almost completely closed.

The second section of the travel may have a maximum path length of 40% and preferably at most 25% of the total path length of the travel. Thus, the majority of the wing movement is in the safe state.

A special embodiment of the invention provides that in the mounted state of the functional unit, a gap formed between the frame and the wing has a width of 20 mm or less, preferably 10 mm or less, and more preferably 8 mm or less, when the Coupling element is located at a transition from the first portion of the travel to the second portion of the travel. In such a narrow gap can reach no limbs, so there is no risk of entrapment and the safety function can be easily disabled. The gap may be the gap that exists between a closing edge of the wing and an opposite portion of the frame.

There are various ways to implement a safety function via the control of the drive. In particular, the control device may be designed to instruct a partial load operation of the drive to provide the safety function and / or to trigger an emergency shutdown of the drive in the event of a resistance to the movement of the wing.

According to one embodiment of the invention, the functional unit is an opener / closer unit, which is designed in the mounted state for automatically opening and closing the wing, at least during an automatic phase. In particular, such an opener / closer unit may be a door drive for fully opening and closing the sash. However, the coupling element of the opener / closer unit can also be releasably coupled to the wing or the frame, in particular be latched, and be movable by means of the drive between a retracted position and an extended position. It is then not necessary to move the wing by means of the drive of the opener / closer unit to the fully open state. Rather, it may be provided to open the wing during an automatic phase by means of the opener / closer unit only a gap and then release the coupling of the control element with the wing or the frame, so that the user perform the further opening by hand can.

According to an alternative embodiment of the invention, the functional unit is a bearing unit, which is designed for rotatable mounting of the wing on the frame in the assembled state, wherein the base body is designed for attachment to the frame first bearing part and the coupling element is designed for attachment to the wing second bearing part , and wherein in the assembled state of the functional unit, the second bearing part is displaceable by means of the drive relative to the first bearing part transversely to the frame plane, preferably by an offset of at least 30 mm. By moving the bearing parts of the wing can be pushed away from the frame and so adjusted to a ventilation state. By moving back the bearing parts, the wing can be used again on the frame. A corresponding storage unit can be used on the one hand for parking and on the other hand for tilting the wing. To allow the tilting, a corresponding range of motion for the tilting movement may be provided.

Placing the band-side wing edge by means of several storage units allows opening of the wing even with concealed arrangement of the fitting system. For concealed fittings, the axis of rotation is with the wing closed within the frame profiles, so that it would come to an abutment of the profile elements without prior stopping.

According to a further embodiment of the invention, the functional unit is a closure unit, which is formed in the mounted state for releasably fixing the wing on the frame, wherein the coupling element is a closure element, which by means of the drive between a wing on the frame holding closed position and the wing releasing Opening position is movable. Such a closure unit serves for a motorized locking and unlocking of the wing.

The closure element may, for example, be a holding claw which can be pivoted about a pivot axis and which is designed for a locking engagement with a locking pin or the like. Alternatively, the closure element is a parallel to the frame frame plane displaceable pin which engages in the mounted state of the closure unit in a holding receptacle, wherein on a wall portion of the holding receptacle is formed a slope through which a running parallel to the frame frame plane movement of the pin in a run of the pin transverse to the frame plane extending movement of the wing can be implemented.

Preferably, the pin is adjustable transversely to the direction of displacement in at least one adjustment, so that it can be made after mounting in a desired position for emergence on the slope.

A functional unit according to the invention can be provided either for attachment to the frame or for attachment to the wing. However, a frame-side attachment is advantageous in that the laying of the control and supply lines is simplified. Furthermore, the casement can be made comparatively narrow, which is visually appealing.

The drive can be designed as an electromotive, magnetic, pneumatic or hydraulic drive. Preferably, the drive comprises a servomotor. The drive can be arranged on the base body.

A functional unit according to the invention can have a communication device by means of which it can communicate with a further functional unit and / or with a central control unit. Several functional units of a fitting can thus be networked with each other.

The invention also relates to a fitting for a component, in particular for a window or a door, with a functional unit as described above.

According to the invention, such a fitting comprises a holding receptacle which comprises a first receiving part designed to be fastened to the wing or to the frame and a second receiving part which can be adjusted in at least one adjustment direction and on which a receiving opening is formed. Depending on the embodiment, the second receiving part can be adjustable in one or more directions, preferably manually. The adjustable holding receptacle allows a simple adjustment of the contact pressure.

The invention also relates to a component for closing an opening, in particular a window or a door, with a frame, a relative to the frame movable wings and a fitting.

According to the invention, the fitting comprises at least one functional unit as described above. Depending on the application, the fitting may comprise a plurality of different functional units, for example two storage units and one opener / closer unit or two storage units and one closure unit.
