Description

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

The fitting arrangement can optionally be operated by the actuating motor and the actuating device, i.e. 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 motor-driven fitting arrangements increase ease of use and, for example, also enable remote-controlled actuation, e.g. to bring the wing in the frame from a closed position to a tilted position - and vice versa.

A disadvantage of such fitting arrangements is their generally complex and error-prone construction.

It is therefore an object of the present invention to provide a fitting arrangement of the aforementioned type which is simple in construction and at the same time can be operated reliably.

The DE 196 03 770 A1 discloses a fitting arrangement with the features of the respective preamble of the independent claims.

This object is achieved by a fitting arrangement according to independent claim 1. According to the invention, the actuating motor and components for drivingly coupling the actuating motor to the locking bar are designed to be arranged in a region of a lower edge of the wing, in the position of use. According to the invention, the actuating motor and the components mentioned are designed to be arranged in a region of a lower edge of a casement, for example in a window frame.

This design is accompanied by the advantage that the energy required for actuating the fitting arrangement by the actuating motor can be supplied in a simple manner, since no complex wiring for power supply is required even when the sash is tilted. In this state, too, the lower edge of the wing is in close spatial contact with the frame assigned to the wing, so that corresponding electrical contacts can be designed to be comparatively simple.

It can be provided that the actuating motor can be coupled to the locking rod in a drive-effective manner via a driver element, the locking rod having a drive pin which, in a drive-effectively coupled state, interacts with one of two mutually facing drive surfaces of the driver element which can be moved by the actuating motor. For example, the driver element in this embodiment - figuratively speaking - is designed as a flat U-profile, the inner sides of the legs of the U-profile forming the drive surfaces. By moving the U-profile laterally, either one or the other inside of the U-profile can come into contact with the drive pin brought in order to be able to move it - and thus also the locking bar. The section of the U-profile connecting the legs defines the path that the driver element has to travel in order to move from a coupling with one of the drive surfaces to a coupling with the other drive surface. The section connecting the legs thus defines a kind of "idling between two drive-coupled states, in which a movement of the driver element is transmitted via the corresponding drive surface to the drive pin and thus ultimately to the locking bar. It goes without saying that a kinematic reversal of the above In this case, the actuating motor is assigned a pin-like driver element, 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 pin-like driver element intervenes.

According to one embodiment, a driver element, which is coupled to the actuating motor in a drive-effective manner, in particular in the form of a pin, is provided, which can be selectively brought into a drive-effective coupling with the locking bar and which engages through the locking bar so that the driver element protrudes from the wing. As a result, the driver element can not only be provided for driving the locking bar, but can also perform additional functions which are useful for reliable operation of the fitting arrangement.

In particular, the driver element can be moved linearly.

A control unit can be assigned to the actuating motor, which is designed such that the driver element is in a first position, in a second position and can be brought into a neutral position, the neutral position being in particular between the first and the second position. According to a structurally simple construction, the control unit is designed in such a way that only the above-mentioned discrete positions can be taken and the taking of further intermediate positions is not provided. Furthermore, the control unit can be designed in such a way that the driver element can automatically be moved into the neutral position after reaching the first and the second position, so that the driver element is always brought back into a well-defined basic or neutral position by a method in the first or the second position.

The driver element can be coupled to the locking bar in such a way that moving the driver element into the first position causes the locking bar to be moved into the first functional position and that moving the driving element into the second position causes the locking bar to be moved 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 configured such that the locking bar can be brought into the third functional position by actuating the actuating device without the driver element participating. In other words, the locking bar should also and in particular only be able to be brought into the third functional position without the cooperation of the actuating motor.

The first functional position of the locking bar defines a locking position of the fitting arrangement, in which the sash is locked in the frame. The second functional position defines a tilt position of the Fitting arrangement in which the sash can be tilted in the frame. The third functional position can define a rotational position of the fitting arrangement, in which the sash can be moved in the frame by rotation, ie can be opened in the usual way.

Reaching through the locking element by the locking bar can be achieved in a simple manner if it has an elongated hole through which the driving element protrudes. The length of the elongated hole in the longitudinal direction of the locking bar can - taking into account the expansion of the driver element in this direction - correspond to the distance required to move the locking bar from the first functional position into the second functional position. If the driver element is moved back into the neutral position after the method in one of the two positions, the configuration described above causes the driver element in the neutral position to be arranged again in the region of one of the ends of the elongated hole or even to strike the end. If a different functional position is to be assumed based on this situation, 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, the actuating motor is coupled to a threaded spindle in a drive-effective manner, the threaded spindle being in a drive-effective connection with the driver element, in particular via a spindle nut. The threaded spindle is in particular at least twice as long as the elongated hole of the locking bar.

In order to be able to provide the required drive power with a compact design of the fitting arrangement, two actuating motors can be used be provided, which are arranged in particular coaxially. For example, a threaded spindle is provided which is driven at both ends - preferably via a gear or also directly - by an actuating motor in each case.

To protect the functional components of the fitting arrangement, the locking bar can be arranged between the actuating motor and a faceplate, which at least in sections covers the locking bar with respect to the outer space of the wing and through which the driver element projects.

To increase operational safety, the fitting arrangement can have a position determining device for determining the position of the locking bar. The position determining device comprises in particular a rotation angle sensor - for example a potentiometer - which is coupled to the locking rod via a gearwheel engaging in recesses in the locking rod.

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

The blocking mechanism can have a release device which is designed in such a way that the blocking mechanism does not interact with the driver element in a neutral position. In particular if the driver element in the first by a method or is automatically brought back into the neutral position in the second position, the release device makes it possible for the wing to be opened for rotation without motorized actuation of the driver element and also not prevented by the components of the motorized actuation system. For example, the locking bar can be brought into the third functional position by the actuating device in order, for example, to be able to open the sash without the locking action of the blocking mechanism described above being contrary to this. This can be particularly relevant in emergencies, in which the opening of the wing is required without the actuation motor being able to be used (for example in the event of a power failure).

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

Alternatively, it is possible for the blocking mechanism to comprise an electromagnet which has a wing-side and a frame-side component. In order to secure the wing when the locking bar is moved 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, in the first and / or in the second functional position of the locking bar, interacts with a locking device which is part of the frame 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 apart from one another, the first locking pin interacting with the locking device in the first functional position of the locking bar and the second locking pin interacting with the locking device in the second functional position of the locking bar. The locking device can be a locking rail or holder, the longitudinal extent of which is shorter than the distance between the first and the second locking pin.

In order to be able to move the sash into the tilting position and back again in a comfortable and reliable manner, in particular automatically and / or remotely, a tilting device is provided. According to the invention, the tilting device is directly or indirectly coupled to the actuating motor and / or the actuating device by means of a mechanical positive guidance. In particular, the locking bar is a component of this coupling. The mechanical positive guidance means that an actuation of the actuating motor or the actuating device not only leads to a movement of the locking bar, but also that an active tilting movement of the wing is generated. The design of the positive guidance ensures through mechanical interacting components that only the desired movement - i.e. the wing can be tilted from a closed position into a tilted position and back.

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 specified in the claims, the description and the accompanying drawings.

Fig. 1A shows a part of a fitting arrangement 10 for windows, doors or the like with a frame and with a wing. The functioning of the fitting arrangement 10 in connection with a window is described below. It goes without saying, however, that the following explanations also apply in a corresponding manner to other areas of application of the fitting arrangement 10.

The fitting arrangement 10 comprises sash-side and frame-side components, ie certain components of the fitting arrangement 10 are assigned to the sash of the window, while other components are assigned to the frame. A locking bar 12 is provided on the wing side and is arranged displaceably along its longitudinal axis. Depending on the position or functional position of the locking bar 12, the sash of the window can assume different positions, namely a locked position, a tilted position or a position which enables the sash to be opened by rotation.

The locking bar 12 is covered at least in sections by a faceplate 14 with respect to the exterior of the wing, not shown. On the side of the locking bar 12 facing away from the faceplate 14, an actuating mechanism 16 is arranged, which comprises two coaxially arranged motors 18. The motors 18 can be operated electrically and, when energized, drive a threaded spindle 20 for a rotary movement, which is converted by means of a spindle nut 22 arranged in a rotationally fixed manner into a linear movement of a driver pin 24 which is fixedly connected to the spindle nut 22 or is formed in one piece. The driver pin 24 protrudes through an elongated hole 26 in the locking bar 12. The driver pin 24 also passes through Fig. 1A Elongated hole of the faceplate 14 not visible, so that the driver pin 24 projects 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 Fig. 1A Components shown in a - in the use position - lower edge of the window sash, more precisely in a lower, horizontal part of the window sash, arranged. Power is supplied via leaf-side and frame-side electrical contacts (not shown) which are in conductive connection when the window sash is arranged in a closed position or in a tilted position relative to the frame receiving the sash. When the window is opened by a rotary movement, the electrical contacts are separated from one another, so that in this state the motors 18 are reliably prevented from being actuated unintentionally. The spatial arrangement of the actuation mechanism 16 in the lower part of the window sash thus enables the power supply for the motors 18 to be designed in a simple and at the same time secure manner.

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

Fig. 1A shows in addition to the wing-side components described above, a blocking rail 34 with a release recess 36. The function of the components 34, 36 is explained in more detail below.

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

Figure 1B it can be seen that the fitting arrangement 10 has, in addition to the electrically operable actuating mechanism 16, a handle 38 through which the locking bar 12 can also be moved. That is, the locking bar 12 can be moved both by the motors 18 and by the handle 38 in order, for example, to be able to bring the window into a tilted state starting from the closed position shown.

Figure 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 attached to the frame of the window in the area Bolt receptacle 42 arranged so that opening the wing is not possible. The driver pin 24 is on the other hand - as well Fig. 1A it can be seen - in the area of the release recess 36 of the blocking rail 34.

In principle, the wing should be able to be opened even if the power supply to the motors 18 fails. In particular, for safety reasons, the rotary opening position should not be able to be reached via the motors 18, but only manually via the handle 38. This means that the fitting arrangement 10 must be designed in such a way that the locking bar 12 can also be displaced without the cooperation of the actuating mechanism 16. The fitting arrangement 10 can do this because, as in the 2A and 2B shown, the locking bar 12 is rotatable by turning the handle 38 to the right when moving from the in 1A and 1B shown situation. Since the driver pin 24 in Fig. 1A is arranged at the right end of the elongated hole 26, the locking bar 12 can be moved to the right without the driver pin 24 preventing this movement. Since the actuation mechanism 16 has not been actuated, the driver pin 24 does not move relative to the release recess 36. When the locking bar 12 is moved, the locking pins 40, 40 'which are firmly attached to it are also moved to the right, as is the case Figure 2B can be seen. The pin 40 is then no longer blocked by the bolt receptacle 42. The pin 40 'also does not stand in the way of opening the wing, since it has not yet been inserted into the bolt receptacle 42.

From the Figure 2A it can also be easily concluded that a further rotary movement of the handle 38 brings the locking bar 12 into a functional position which enables the sash to tilt. The locking bar 12 is shifted further to the right until the driver pin 24 - which does not move when the handle 38 is actuated - strikes the left end of the elongated hole 26, as in FIG Figure 3A you can see. In this state, the locking pin 40 'is blocked by the locking receptacle 42, so that the lower edge of the window is reliably secured against a rotational movement out of the frame. The other components of the fitting arrangement 10 to enable the sash to be tilted are not shown and can be of conventional construction. According to the invention, a movement of the locking bar 12 is converted into an automatic tilting movement of the wing by a mechanical positive guidance.

As an alternative to the manual actuation of the fitting arrangement 10 described above, this can also be actuated by the motors 18. Starting from the in the 1A and 1B "To zero position" shown, the threaded spindle 20 is driven by the motors 18 to a rotary movement, which is converted via the spindle nut 22 into a linear movement of the driver pin 24 to the right. Since the driver pin 24 rests in the “zero position” at the right end of the elongated hole 26, the locking bar 12 is also moved to the right by the movement of the driver pin 24 until the tilting position of the locking bar 12 is reached.

As in Figure 4B is shown, the locking pin 40 'prevents uncontrolled opening of the window sash in this position. In addition, the blocking rail 34, in cooperation with the part of the driver pin 24 protruding from the wing, ensures that even when the Figure 2B shown position of the pin 40, 40 'prevents unintentional opening of the window. In this situation, the pins 40, 40 'do not cooperate with the bolt receptacle 42, which is why they cannot have a securing effect. This take over the driver pin 24 and the blocking rail 34. In other words, the wing is at a transition from that in the Figure 1B position shown to in Figure 4B shown position reliably secured due to the driver pin 24 and the blocking rail 34. An automatic or remote-controlled transition of the window sash from a locked position into a tilted position - and vice versa - is therefore possible without risk.

However, in order to ensure that the sash can also be moved manually from the tilted position into the rotary opening position in an emergency, after reaching the 4A and 4B situation shown automatically ensures - for example by means of a control unit (not shown) which controls the motors 18 - that the driver pin 24 is again moved into a neutral position. That is, it is moved from the right end of the elongated hole 26 to the left up to its left end, so that the section of the driver pin 24 protruding from the wing is arranged in the region of the release recess 36 of the blocking rail 34. This state is in the 3A and 3B shown and corresponds to a "tilt zero position".

If the window is to be closed again, the fitting arrangement 10 must be actuated again starting from the "tilt-zero position". For this purpose, the motors 18 are activated, as a result of which the driving pin 24 is moved to the left and in the process takes the locking bar 12 with it until it reaches the 5A and 5B shown position is reached. Inadvertent opening of the wing - analogous to the situation described above - is reliably prevented when the locking bar 12 is displaced by the area of the blocking rail 34 arranged on the left of the release recess 36 in cooperation with the driving pin 24.

After the locking bar 12 has been moved into the closed functional position, the driver pin 24 is automatically moved back into the neutral position, in which the nut 22 is located approximately in the middle of the threaded spindle 20. The in the 1A and 1B The situation shown is then reached again and the fitting arrangement 10 is in the “zero position”, which makes it possible to move the locking bar 12 either manually - ie by means of the handle 38 - into the rotary opening position or into the tilting position or through the motors 18 to move to the tilt position.
