Description

The present invention relates to a fitting arrangement for windows, doors or the like with a frame and with a wing, wherein the fitting arrangement on the wing side comprises a locking bar, a mechanical - in particular manually operable - actuating device and at least one actuating motor.

The fitting arrangement is selectively operable by the actuating motor and actuator, i. the locking bar is displaceable and can be brought into a first and a second functional position both by the actuating motor and by the actuating device. Such motorized fitting arrangements increase the ease of use and, for example, also allow for remote operation, e.g. to bring the wing in the frame from a closed position to a tilted position - and vice versa.

The documents DE 196 03 770 A1 and EP 1 283 318 A1 each discloses a fitting arrangement with the features of the preamble of claim 1.

The disadvantage of such hardware arrangements, however, is their usually complex and error-prone design.

It is therefore an object of the present invention to provide a fitting arrangement of the aforementioned kind, which is simple in construction and at the same time reliably operable.

This object is achieved by a fitting arrangement according to claim 1.

The actuating motor and components for the drive-effective coupling of the actuating motor with the locking bar can be designed for arrangement in a region of a - in use position - lower edge of the wing. In particular, the actuating motor and the said components for arrangement in an area of a lower edge of a sash, for example, in a window frame, formed.

This design is accompanied by the advantage that the required for an actuation of the fitting assembly by the actuating motor energy can be supplied in a simple manner, since even in a tilted state of the wing no complicated wiring for power supply is required. The lower edge of the wing is namely in this state in close spatial contact with the frame associated with the wing, so that corresponding electrical contacts can be made relatively simple.

It can be provided that the actuating motor is drive-effectively coupled via a driver element with the locking bar, wherein the locking bar has a drive pin which cooperates in a drive-coupled state with one of two mutually facing drive surfaces of the movable by the actuating motor driver element. For example, the driver element in this embodiment - figuratively speaking - designed as a flat U-profile, wherein the inner sides of the legs of the U-profile form the drive surfaces. By a lateral displacement of the U-profile can either the one or the other inside of the U-profile are brought into contact with the drive pin to this - and thus also the locking bar - can also move. The leg connecting portion of the U-profile defines the path that the driver must travel to get from a coupling with one of the drive surfaces to a coupling with the other drive surface. The section connecting the limbs thus defines a kind of "idling" between two states coupled in an effective manner in which a movement of the driver element is transmitted via the corresponding drive surface to the drive journal and thus ultimately to the locking bar In this case, a pin-like driving element is associated with the actuating motor, while the locking bar comprises two drive surfaces, for example two lugs, a U-shaped coupling element, a recess and / or an opening, between and into which the peg-like Driver element engages.

The above-described object is - in particular with regard to a reliable actuation of the fitting assembly - according to the invention achieved that a drivingly coupled to the actuating motor, in particular pin-like trained driver element is provided which can be selectively brought into the drive rod coupling with the locking bar and which passes through the locking bar , so that the driver protrudes from the wing. The driver element can thereby be provided not only for driving the locking bar, but additionally fulfill other functions that are useful for reliable operation of the fitting arrangement.

In particular, the driver element is linearly movable.

The actuating motor may be assigned a control unit which is designed such that the driver element can be brought into a first position, into a second position and into a neutral position, wherein the Neutral position is in particular between the first and the second position. According to a structurally simple design, the control unit is designed so that only the aforementioned discrete positions can be taken and the receipt of further intermediate positions is not provided. Further, the control unit may be configured such that the driver element after reaching the first and the second position is automatically moved into the neutral position, so that the driver element always brought back to a well-defined basic or neutral position by a method in the first or second position becomes.

The entrainment element can be coupled to the locking bar in such a way that a movement of the entrainment element into the first position causes the locking bar to move into the first functional position and that a movement of the entrainment element into the second position effects a displacement of the locking bar into the second functional position. In particular, the locking bar can be brought into a third functional position which lies between the first and the second functional position. It is particularly advantageous if the locking bar and the driver element are designed such that the locking bar can be brought by an actuation of the actuating device without the participation of the driver element in the third functional position. In other words, the locking bar should also and in particular be brought into the third functional position only without the involvement of the actuating motor.

According to one embodiment of the fitting arrangement defines the first functional position of the locking bar a locking position of the fitting assembly in which the wing is locked in the frame. The second functional position defines in this embodiment, a tilted position of the fitting assembly, in which the wing in the frame can be tilted. The third functional position may define a rotational position of the fitting assembly, in which the wing is movable in the frame by rotation, ie, can be rotationally opened in the usual way.

A reaching through the driver element by the locking bar can be achieved in a simple manner, if this has a slot through which projects the driver element. The length of the slot in the longitudinal direction of the locking bar can - taking into account the extent of the driver element in this direction - correspond to the distance that is required to move the locking bar from the first functional position to the second functional position. If the driver element is moved back into the neutral position after the process in one of the two positions, the embodiment described above causes the driver element is disposed in the neutral position again in the region of one of the ends of the slot or even strikes at the end. If, starting from this situation, another functional position is assumed, an actuation of the actuating motor and a corresponding movement of the driver element are immediately converted into a movement of the locking bar.

According to a structurally simple embodiment of the fitting arrangement of the actuating motor is drive-effectively coupled to a threaded spindle, wherein the threaded spindle is in particular via a spindle nut with the driver element in driving connection. The threaded spindle is in particular at least twice as long as the slot of the locking bar.

In order to provide the required drive power at the same time compact design of the fitting assembly, two actuation motors be provided, which are arranged in particular coaxially. For example, a threaded spindle is provided, which is driven at both ends - preferably via a transmission or directly - by a respective actuating motor.

To protect the functional components of the fitting arrangement, the locking bar can be arranged between the actuating motor and a face-plate rail which covers the locking bar at least in sections relative to the outer space of the wing and through which the driving element protrudes.

To increase the reliability, the fitting arrangement may have a position determining device for determining the position of the locking bar. In particular, the position-determining device comprises a rotation angle sensor-for example a potentiometer-which is coupled to the locking bar via a toothed wheel engaging in recesses of the locking bar.

In order to secure the wing in the frame during the displacement of the locking bar from the first to the second functional position, the fitting arrangement may comprise on the frame side a blocking mechanism. The blocking mechanism ensures that the wing can not make any unintentional movements relative to the frame during the movement of the locking bar from the first to the second functional position, and vice versa.

The blocking mechanism may have a release device which is designed such that the blocking mechanism does not interact with it in a neutral position of the driver element. In particular, when the driver element by a method in the first or in the second position is automatically brought back to the neutral position, the release device allows that a rotational opening of the wing without a motor actuation of the driver element is possible and is not prevented by the components of the motorized actuating system. For example, the locking bar can be brought by the actuating device in the third functional position, for example, to be able to open the wing, without the above-described securing effect of the blocking mechanism opposes that. This can be particularly relevant in emergencies, in which the opening of the wing is required, without being able to resort to an actuation of the actuating motor (such as a power failure) or should.

In particular, the blocking mechanism is a frame-side component, for example a rail which can be fastened to the frame, with which the driver element interacts during the displacement. The release device can be used in this construction e.g. be a recess in the rail through which the driver element can be performed in the neutral position.

Alternatively, it is possible that the blocking mechanism comprises an electromagnet having a wing-side and a frame-side component. To effect the securing of the wing during a displacement of the locking bar between the first and the second functional position, the electromagnet is energized.

According to one embodiment of the fitting arrangement, the locking bar is provided with at least one locking pin, which cooperates in the first and / or in the second functional position of the locking bar with a locking device which is a frame-side component of the fitting arrangement is. In particular, the locking bar is provided with a first locking pin and with a second locking pin, which are spaced from each other, wherein the first locking pin cooperates in the first functional position of the locking bar with the locking device and wherein the second locking pin cooperates in the second functional position of the locking bar with the locking device. The locking device may be a locking rail or receptacle, whose longitudinal extent is shorter than the distance between the first and the second locking pin.

In order to bring the wing in the frame - in particular automatically and / or remotely controlled - in a tilted position and back again in a comfortable and reliable manner, a tilting device can be provided. The tilting device is in particular driven by a mechanical forced operation directly or indirectly coupled to the actuating motor and / or the actuator drive-effective. In particular, the locking bar is a component of this coupling. The mechanical forced operation causes an actuation of the actuating motor or the actuator not only leads to a movement of the locking bar, but also actively a tilting movement of the wing is generated. The design of the positive guidance ensures by mechanical interacting components that only the desired movement - i. a tilting of the wing from a closed position into a tilted position and back - can be performed.

The invention further relates to a window, a door or the like with a frame, with a wing and with a fitting arrangement according to at least one of the embodiments described above.

Further embodiments of the invention are indicated in the claims, the description and the attached drawings.

the fitting arrangement schematically in the corresponding operating states.

Fig. 1A shows a part of a fitting assembly 10 for windows, doors or the like with a frame and with a wing. In the following, the operation of the fitting assembly 10 will be described in connection with a window. It is understood, however, that the following statements apply in a corresponding manner for other applications of the fitting assembly 10.

The fitting assembly 10 includes wing-side and frame-side components, ie, certain components of the fitting assembly 10 are associated with the wing of the window, while other components are associated with the frame. Wing side a locking bar 12 is provided which is slidably disposed along its longitudinal axis. Depending on the position or functional position of the locking bar 12, the wing of the window can assume different positions, namely a locked position, a tilted position or a position that allows the opening of the sash by a rotation.

The locking bar 12 is at least partially covered by a faceplate 14 relative to the outer space of the wing, not shown. On the side facing away from the faceplate rail 14 of the locking bar 12, an actuating mechanism 16 is arranged, which comprises two coaxially arranged motors 18. The motors 18 are electrically operable and drive when energized, a threaded spindle 20 to a rotary motion, which is implemented by means of a rotatably mounted spindle nut 22 in a linear movement of a fixedly connected to the spindle nut 22 or integrally formed driving pin 24. The driving pin 24 projects through a slot 26 in the locking bar 12. The driving pin 24 also passes through in Fig. 1A not to be seen oblong hole of the faceplate 14, so that the driving pin 24 protrudes into the outer space of the window sash, on which the locking bar 12 and the actuating mechanism 16 are arranged.

In order to simplify a power supply for the motors 18, the in Fig. 1A shown components in a - in use position - lower edge of the sash, more precisely in a lower, horizontally extending part of the sash, arranged. Power is supplied via wing side and frame side electrical contacts (not shown) which are in conductive communication when the window sash is disposed in a closed position or a tilted position relative to the sash receiving frame. When opening the window by a rotary movement, the electrical contacts are separated from each other, so that in this state reliably prevents the motors 18 are actuated unintentionally. The spatial arrangement of the actuating mechanism 16 in the lower part of the window sash thus enables a simple and at the same time safe design of the power supply for the motors 18.

In order to always be able to detect in which position the locking bar 12 is, a position determining system 28 is provided, which has a coupled with a gear 30 potentiometer. The gear 30 engages in corresponding recesses 32 of the locking bar 12, so that the gear 30 is set in a movement of the locking bar 12 in a rotational movement. From the measured rotational movement of the toothed wheel 30, the potentiometer finally determines the position / position of the locking bar 12 in a manner known per se.

Fig. 1A shows in addition to the wing-side components described above nor a blocking rail 34 with a release recess 36. The function of the components 34, 36 will be explained in more detail below.

Fig. 1B schematically shows the essential components of the fitting assembly 10 in the same state as in Fig. 1A , The wing of the window is locked in this state in the frame, the driving pin 24 is in a so-called zero position ("to zero position").

Fig. 1B It can be seen that the fitting assembly 10 next to the electrically operable actuating mechanism 16 has a handle 38 through which the locking bar 12 is also movable. That is, the locking bar 12 is displaceable both by the motors 18 and by the handle 38, for example, to bring the window starting from the closed position shown in a tilted state can.

Fig. 1B further shows that the locking bar 12 has a first locking pin 40 and a second locking pin 40 '. In the state shown, the locking pin 40 is in the region of one attached to the frame of the window Latch receptacle 42 arranged so that an opening of the wing is not possible. The driving pin 24 is in contrast - as well Fig. 1A can be seen - in the region of the release recess 36 of the blocking rail 34th

In principle, the wing should be able to be opened even in the event of a power failure of the motors 18. In particular, the rotational opening position for safety reasons should not be achieved via the motors 18, but only manually via the handle 38. That is, the fitting assembly 10 must be configured such that the locking bar 12 can be moved without the cooperation of the actuating mechanism 16. The fitting assembly 10 is able to do this because, as in the FIGS. 2A and 2B shown, the locking bar 12 is displaced by turning the handle 38 to the right, if one of the in the Fig. 1A and 1B shown situation. Since the driving pin 24 in Fig. 1A is arranged at the right end of the slot 26, the locking bar 12 can be moved to the right without the driver pin 24 prevents this movement. Since the operating mechanism 16 has not been operated, the driving pin 24 does not move relative to the releasing recess 36. When moving the locking bar 12 and the locking pins 40, 40 'are fixedly moved to the right, such as Fig. 2B can be seen. The pin 40 is then no longer blocked by the bolt receptacle 42. Also, the pin 40 'is not an opening of the wing in the way, since he is not retracted into the bolt receptacle 42.

From the Fig. 2A Furthermore, it can readily be concluded that a further rotational movement of the handle 38 brings the locking bar 12 into a functional position which makes it possible to tilt the wing. The locking bar 12 is thereby moved further to the right until the driving pin 24 - which does not move upon actuation of the handle 38 - abuts the left end of the slot 26, as in FIG Fig. 3A you can see. In this state, the locking pin 40 'is blocked by the bolt receptacle 42, so that the lower edge of the window is reliably secured against rotational movement out of the frame. The other components of the fitting assembly 10 to allow the tilt of the wing are not shown and may be of conventional construction. In particular, it is also possible that a movement of the locking bar 12 is converted by a mechanical positive guidance in an automatic tilting movement of the wing.

Alternatively to the above-described manual operation of the fitting assembly 10, this can also be actuated by the motors 18. Starting from the in the Fig. 1A and 1B shown "to-zero position", the threaded spindle 20 is for this purpose driven by the motors 18 to a rotational movement, which is converted via the spindle nut 22 in a linear movement of the driving pin 24 to the right. Since the driving pin 24 rests in the "to-zero position" at the right end of the slot 26, the locking bar 12 is also moved by the movement of the driving pin 24 to the right until the tilted position of the locking bar 12 is reached.

As in Fig. 4B is shown, the locking pin 40 'in this position prevents uncontrolled opening of the window sash. In addition, the blocking rail 34 in cooperation with the protruding from the wing part of the driving pin 24 ensures that even when driving through in the Fig. 2B shown position of the pins 40, 40 'unintentional opening of the window is prevented. In this situation, the pins 40, 40 'namely do not interact with the latch receptacle 42, which is why they can not develop a locking effect. This take over the driving pin 24 and the blocking rail 34. In other words, the wing at a transition from in the Fig. 1B shown position to the in Fig. 4B shown position due to the driving pin 24 and the blocking rail 34 reliably secured. An automatic or remote controlled transition of the sash from a locked position to a tilted position - and vice versa - is therefore possible safely.

However, to ensure that the wing can be brought manually in an emergency from the tilted position in the rotary opening position, after reaching the in the FIGS. 4A and 4B shown situation automatically ensured - for example by means of a motor 18 controlling the control unit (not shown) - that the driving pin 24 is moved again in a neutral position. That is, it is moved from the right end of the slot 26 to the left to its left end, so that the protruding from the wing portion of the driving pin 24 in the region of the release recess 36 of the blocking rail 34 is arranged. This condition is in the FIGS. 3A and 3B shown and corresponds to a "zero-tilt position".

If the window is to be closed again, the fitting assembly 10 must be operated again from the "zero-tilt position". For this purpose, the motors 18 are activated, whereby the driving pin 24 is moved to the left while the locking bar 12 entrains until in the Figs. 5A and 5B shown position is reached. Unintentional opening of the wing is - in analogy to the situation described above - reliably prevented in the displacement of the locking bar 12 by the left of the release recess 36 arranged portion of the blocking rail 34 in cooperation with the driving pin 24.

After the locking bar 12 has been moved to the closed functional position, the driving pin 24 is automatically moved again into the neutral position, in which the nut 22 is located approximately in the middle of the threaded spindle 20. The in the Fig. 1A and 1B shown situation is then reached again and the fitting assembly 10 is in the "to-zero position", which makes it possible to bring the locking bar 12 either manually - ie by the handle 38 - in the rotational opening position or in the tilted position or by the motors 18 to move into the tilted position.
