Description

The invention relates to a window system for a building.

Monitoring the closed state of the windows of a building is usually time consuming, especially for buildings with a large number of windows, such as office buildings and the like. Even if the closed state of the windows can be seen from outside the building, which is usually not possible with only ajar and unlocked windows, with conventional window systems each window must be closed and locked individually and by hand.

From DE-A-32 23 808 a window with a manually operated turn-tilt locking fitting is known, the drive rod arrangement of which opens a gap in the position releasing the window for a tilting movement about a horizontal axis by means of an electric motor integrated into the window handle for ventilation purposes can be. The electric motor drives independently gig of the handle blocked by a torque arm on the drive rod assembly. The drive rod arrangement, which is movable in the circumferential direction of the sash frame of the window in the usual manner, on the one hand locks the window on its frame and tilts the sash frame into the slightly open ventilation position via a wedge gear acting between the frame and the drive rod arrangement. The electric motor is assigned a controller which responds to a room air parameter, for example to gaseous or visible impurities in the room air, by means of a sensor, which automatically opens the window when the monitored parameter exceeds a predetermined value or closes again when the value falls below it. In this way, the energy requirement for heating or cooling the room air can be kept to a minimum.

It is an object of the invention to provide a window system with increased ease of use and / or monitoring, the installation effort for installing the window system being low.

This object is achieved by the features specified in claim 1. The invention is particularly suitable for windows, the casement of which is provided with a manually operated turn-tilt locking fitting, which can be released alternately for a pivoting movement about a vertical axis or a pivoting movement about a horizontal axis. The locking fitting is locked or unlocked by a motor arrangement regardless of the possibility of operating it manually. The motor arrangement also provides for an opening and closing movement of the casement, preferably for the tilting movement about the horizontal axis.

The motor arrangements are controlled by microprocessors, which detect the locking state of the locking fitting and / or the closing state of the casement via sensor arrangements. Each of the windows is assigned its own microprocessor, which, however, can alternatively take over the control of the motor arrangements and the detection of the signals from the sensor arrangements in each case in a group of windows.

The individual microprocessors, which are arranged locally adjacent to the windows assigned to them in order to reduce the amount of cabling, can be controlled remotely from the assigned window via remote control devices. The remote control device allows the window to be operated e.g. from sight within a room of the building, for example from a seat that is out of reach of the window.

In addition, the microprocessors are preferably connected via a data bus, for example a ring line, to a common, centrally located monitoring center, in which the pivoting and / or locking positions of the windows detected by the sensor arrangements can be displayed individually or in groups on an optical display device. The data processing capacity of the microprocessors is therefore not only used for remote control operation of the motor drives, but also for data transmission for monitoring purposes. The program control of the microprocessors synchronizes the operating sequence of the motor arrangements, in particular if they have separate motors for the locking drive of the locking fitting and the pivoting drive of the casement. Thus, only short trigger signals have to be transmitted via the remote control devices, which is the case with wireless users Remote control devices with transmitters that are preferably operated independently of the network are advantageous for reducing the power requirement. The occupancy of the data connection to the monitoring center can also be limited in time with the aid of the locally arranged microprocessors, as a result of which the number of microprocessors and windows which can be connected to the monitoring center can be increased considerably. This is particularly advantageous if the monitoring center is also provided with a central operating device by means of which the windows of the microprocessors can be controlled individually, selectively or in groups, or all together.

In a preferred embodiment, the motor drive comprises a locking motor driving the locking fitting and a separate wing pivot motor driving the pivoting movement. The separation of the motors has the advantage that even conventional tilt and turn locking fittings can be easily and optionally retrofitted with a motor drive. The microprocessor switches the motors on one after the other, namely for the opening movement first the locking motor in the unlocking direction and then the wing swivel motor in the opening direction and for the closing movement first the wing swivel motor in the closing direction and then the locking motor in the locking direction. Limit switches, to which the microprocessor responds, are expediently assigned to both the locking motor and the wing swivel motor. In order to be able to exclude mutually overlapping switch-on times of the two motors with certainty, it is provided in a preferred embodiment that the microprocessor actively brakes the motors when the associated limit switches are actuated, for example by the Power lines of the electric motors are short-circuited.

In a preferred embodiment, the microprocessor monitors the current of the electric motors of the motor arrangements. If the motor arrangement is inadvertently or blocked by attempts at sabotage, the motor current rises above a threshold value monitored by the microprocessor. The microprocessor then generates a monitoring signal which represents the blocking of the motor arrangement and which is selectively displayed in the monitoring center in association with the window or the group of windows and, if appropriate, is used to trigger the alarm. In order to be able to distinguish only a brief inhibition of the motor arrangement from an actual blocking, the monitoring signal is expediently only generated if it occurs for the duration of a predetermined time interval. After the predetermined time interval has expired, the motor arrangement is then switched off in order to avoid overload damage.

The remote control device connected to the microprocessor can be cable remote controls, in which a control panel or the like which is arranged at a distance from the window is connected to the microprocessor via a connecting cable. However, the remote control device preferably works wirelessly and comprises a wireless transmitter, in particular an infrared transmitter, which controls the microprocessor via a receiver connected to the microprocessor.

In a preferred embodiment of the invention, the central operating device assigned to the monitoring center not only allows the selective or collective control of the windows, but also the selective or collective blocking of the motor arrangements, in particular by blocking the microprocessors against control by the remote control devices assigned to the microprocessors. In this way, the windows can be selectively or collectively locked against remote control to increase the security. Since this electrical blocking does not affect the manual operation of the locking fitting, the window can still be opened manually in emergencies. The window can also be equipped with alarm contacts that trigger an alarm system via the monitoring center if the window is opened manually despite the microprocessors being blocked. Additionally or alternatively, however, a blocking device which mechanically blocks the drive rod arrangement of the locking fitting can also be provided, which also locks the drive rod arrangement in its locked position against manual operation of the locking fitting. To increase The sabotage security is expediently provided that the blocking device has a bolt that is resiliently biased into the blocking position and that has to be released for each unlocking movement of the drive rod arrangement by energizing the electromagnet. The excitation of the electromagnet is controlled by the microprocessor so that it can in turn be blocked centrally. In order to be able to open the window manually when the system is not centrally blocked, switch contacts for controlling the electromagnet can be provided on the handle of the locking fitting.

The remote control of the closed state of a window explained above can also be used for the control of the window depending on a state parameter, in particular of the room air, even if no monitoring center is provided for the central closed state display or for the central operation of the window. In this respect, the aspect claimed in claim 10 has independent meaning. In this aspect of the invention, at least one window is provided, which has a manually operated locking fitting, preferably designed as a tilt and turn fitting. A motor arrangement drives both the locking fitting and the pivoting movement of the casement of the window. The motor arrangement is controlled by a controller which responds by means of at least one sensor to a state parameter, in particular the room air in the building. The control in this case comprises a first control part connected via a line connection to the sensor and a wireless transmitter and a likewise connected via a line connection to the motor arrangement and a receiver assigned to the transmitter connected second control part. While the second control part is expediently arranged adjacent to the window, the first control part can be arranged at a location suitable for detecting the state parameter, without having to lay cables or the like to the second control part during assembly. The transmitter is in turn expediently an infrared transmitter, preferably a battery-operated infrared transmitter, and the second control stage is again preferably designed as a microprocessor, which has the advantage that the system in the manner explained above is a monitoring center and a central operating device can be supplemented.

In a preferred embodiment, the sensor of the control system detects the relative humidity of the room air. In this way, the rooms of the building can be ventilated depending on the relative humidity, which prevents mold growth, especially in rooms where there is a risk of moisture. Alternatively or additionally, sensors responsive to the temperature or the CO₂ content of the room air can be provided in order to control the room climate as a function thereof. The control is expediently carried out in such a way that the window is opened when the level of the room air parameter detected by the sensor is above a first threshold and that the window is closed when the level is below a second threshold which is lower than the first threshold. The resulting hysteresis allows the sensitivity to be adjusted and prevents control oscillations.

Additionally or alternatively, sound level sensors can also be provided instead of the sensors explained above that respond to the sound level outside the building and close the window when the sound level is above a predetermined value. This sound level-dependent control of the closing movement of the window can also be implemented without remote control, since the shell sensor is expediently arranged in the region of the window.

Another variant, which can also be implemented without remote control, is that at least one of the windows is controlled by a sensor which responds to the flow velocity of the room air, in particular in the area of the window. In this way, at least one of the windows can be closed automatically when there are drafts in the room.

Another aspect of the invention, which also has independent meaning, is claimed in claim 14. This aspect concerns the monitoring of the closed state of a large number of windows, regardless of whether the windows can be locked and / or pivoted by means of a motor, although the motorized drive of the locking and pivoting movement is also preferred here.

The window system in turn comprises a plurality of windows with a manually operated locking fitting, which is preferably designed as a tilt-and-turn locking fitting, which comprises a drive rod arrangement which is concealed in the circumferential direction of the sash frame and which is at least partially covered in a folded peripheral surface of the sash frame of the window. In this aspect of the invention, the monitoring center shows signals from position sensor arrangements in the optical display device conditions of the window or of groups of windows, which respond to the current position of a drive rod arrangement of the locking fitting of the window. The position sensor arrangements are formed in two parts and comprise a first sensor part which is in a fixed drive connection to the drive rod arrangement and a second sensor part which is fixedly connected to the casement or the window frame. This has the advantage that a comparatively large installation space is available along the drive rod arrangement and the comparatively large stroke of the drive rod arrangement can also be used for the reliable triggering of comparatively insensitive sensors.

It goes without saying that in this aspect of the invention, too, the central monitoring device is provided with an optical display device for displaying the closed state of individual windows or groups of windows. Similar to the above variants of the invention, the optical display device can be light-emitting diodes assigned to the individual windows or individual groups of windows, which signal the pivoting state of the window by its signal state. For example, light-emitting diodes of different colors can be provided, for example red for open windows and green for closed windows. In particular in embodiments in which the monitoring center is likewise designed as a computer, for example as a personal computer, the optical display device can be designed as a text display which indicates the location and closed state of the window in alphanumeric characters. Also suitable are display devices with a graphic display, for example in the form of a screen, which is based on a graphic representation of a building floor crack shows the window status.

The monitoring center must be able to distinguish between a large number of windows. This can be done, for example, by cyclically polling the individual controls of the windows or window groups, preferably again in the form of a microprocessor, in a time-division multiplex process for the state of the window by calling up the windows or their microprocessors. Alternatively, the microprocessors can also be assigned code addresses which, together with their signals indicating the window state, they are preferably sent cyclically to the monitoring device.

In a structurally particularly simple variant of a position sensor arrangement, the first sensor part is designed as a magnet attached to the drive rod arrangement and displaceable together with it in the circumferential direction of the casement, while the second sensor part is a magnetic field sensor, in particular a Hall switch. The magnet can be held on an already existing locking pin projecting from the drive rod toward the frame, while the magnetic field sensor is arranged in a locking plate of the frame associated with the locking pin. This configuration has the advantage that it only responds when the window is closed and locked, and that it can be produced with comparatively little design effort. The magnet is in particular provided concealed on the locking pin, so that even when the window is open it cannot be seen that it is part of a position sensor arrangement.

A variant in which several position sensor arrangements are provided offers increased manipulation security hen, of which a first position sensor arrangement responds to the closed position of the sash, a second to the locking position of the drive rod and a third to the unlocking position of the drive rod which enables a pivoting movement of the sash. The second and the third position sensor arrangement can be assigned a magnet which is arranged jointly on the drive rod, the magnetic field sensors being concealed and thus not being able to be arranged within the casement even when the window is open. In both variants of the position sensor arrangements explained above, the magnets and the magnetic field sensors are expediently arranged in the area of the drive rod corner deflection diagonally opposite the corner bearing of the turn-tilt locking fitting. The drive rod corner deflection can be provided as a standard component regardless of the size of the window and is moved out of the frame both during the tilting movement and during the rotating movement of the window, so that the position sensor arrangements respond equally to both types of pivoting movement.

In a further variant of a position sensor arrangement, this is designed as a tappet contact arrangement, the tappet contact part of which is controlled by the drive rod arrangement via an inclined surface gear. The tappet contact part exits through an opening of a faceplate covering the drive rod of the locking fitting of the window in its locking position and is withdrawn behind the faceplate into the casement frame when the window is unlocked and released for the pivoting movement. The drive rod is designed such that it only opens the opening of the faceplate in the locked position, but in the unlocked position it conceals it. With the window open the plunger contact part is thus covered, which increases the security against manipulation of the position sensor arrangement.

In a preferred embodiment, the tappet contact part is a lever part which is articulated on the faceplate and provided with a cam surface and which cooperates with a cam part which is firmly connected to the drive rod. The lever part is expediently designed as a two-armed lever, the lever arms of which form cam surface areas inclined at an obtuse angle to one another, so that the cam part controls both directions of movement of the lever part.

In variants in which the drive rod arrangement can be controlled not only manually but also via a motor arrangement, limit switches provided on the motor arrangement can also be used as position sensors.

As already mentioned, the monitoring center can be designed so that it displays the status of the windows either individually or in groups. In order to take up as little time as possible for the data connections between the controls or microprocessors of the individual windows and the monitoring center, the signals of the position sensor arrangements are already linked to one another on the window side when the status is displayed in groups. Insofar as microprocessors are provided, this can take place in these. For the sake of simplicity, however, the individual position sensor arrangements, in particular if they are switching contacts, are connected to one another in a logical AND circuit.

As already mentioned, the locking fitting of the window on the one hand and the pivoting movement of the window on the other hand are expediently controlled by separate motors. In the drive known from DE-A-32 23 808 for a locking fitting which can also be operated manually, the electric motor is installed in the shaft part of a hand turning handle coaxially with the axis of rotation of the turning handle and drives the one in engagement with the drive rod gear of the tilt and turn locking fitting Output mandrel via a gear transmission. The rotary handle of the known motor arrangement is therefore comparatively large.

The manual twist grip can be made considerably smaller if its transmission connecting the motor with the output mandrel leading to the drive rod gear comprises a spindle drive, the threaded spindle of which is driven by the motor and whose axis is arranged transversely to the axis of rotation of the lever grip in the lever direction thereof and the spindle nut of which in the lever handle along the threaded spindle is slidably guided rack which meshes with a pinion seated on the output mandrel. In this embodiment, the motor also expediently sits coaxially with the threaded spindle in the lever handle, which therefore differs from the lever handle of conventional hand-operated rotary handles essentially only by a somewhat larger diameter. The drive described above for a locking fitting, in particular a turn-tilt locking fitting, can also be used in window systems other than the systems explained above. Claim 30 accordingly has independent meaning.

In the known locking drive, the manual Rotary handle axially movably guided on a handle base part connected to the casement. The torque arm is designed as a pin which is lifted out of the handle base part when the hand rotary handle is lifted axially. With such a configuration, the pivot bearing of the handle must be designed to be comparatively stable and complex in order to be able to cope with continuous use. The design effort of the hand twist grip can be reduced if the handle base part holding the lever grip on the sash frame extends substantially over the entire length of the lever grip and the bolt of the torque support coupling is arranged at the free end of the lever grip. At the same time, tappet contacts between the lever handle and the handle base part can be provided at the free end of the lever handle, via which the motor arranged in the lever handle and possibly its limit switches are connected to the motor control. Insofar as the plunger contacts are arranged in a plurality of rows running radially to the axis of rotation of the lever handle, they are radially offset from one another in the rows from row to row, so that they cannot overlap with counter-contacts of other tappet contacts during manual rotation of the lever handle.

Another aspect of the invention relates to the pivot drive of the casement separate from the locking drive, which, like the locking drive explained above, can also be retrofitted to a window provided with a locking fitting, in particular a tilt-and-turn locking fitting. The swivel drive comprises an electric motor which is arranged on a frame on the window frame and which drives a scissor lever which extends essentially to the plane of the window frame mens parallel axis is pivotally mounted on the support part of the electric motor. In order to be able to manually open the sash frame independently of the swivel drive, the end of the scissor lever which is remote from the axis is coupled to a drive rod of the drive rod arrangement of the sash frame via a releasable travel compensation coupling. The travel compensation coupling comprises a first coupling part in the form of an elongated rail part and a second coupling part in the form of a slider guided along the rail part. The first coupling part is fixedly connected to the drive rod and is in the closed position of the scissor lever running in the circumferential direction of the frame when the locking fitting is locked out of engagement with the second coupling part provided on the scissor lever. The coupling ratios are chosen so that the coupling parts in the closed position of the scissor lever only engage in the drive rod position intended for motorized pivoting operation, for example the tilting position. Between the tilting position and the locking position of the drive rod, this passes through a position in which the window is released for a torsional vibration. The window can be opened manually in the rotary position. When the espagnolette fitting is in the tilted position, the two coupling parts of the travel compensation coupling interlock, and the window can be tilted and closed by a motor. When using the locking drive described above, the connecting rod fitting can be adjusted both by motor and manually, so that the window can be opened manually in emergencies, at least in the closed position, if the coupling parts are suitably dimensioned. The two coupling parts can be a mushroom head on the scissor lever and one lengthways act the guide rod extending guide rail with a substantially C-shaped cross section, as they are also used as a travel compensation coupling in conventional hardware scissors of tilt and turn lock fittings.

Particularly slim embodiments of the swivel drive are obtained if the gear coupling the motor with the scissor lever is designed as a spindle drive with a threaded spindle which extends in the circumferential direction of the frame and is driven by the electric motor and a spindle nut which is articulatedly connected to the swivel lever at a distance from the swivel axis. The spindle nut is expediently guided on opposite walls of a housing enclosing the electric motor and the spindle drive, the axis of the scissor lever then penetrating a recess, for example an elongated hole in the spindle nut, and the spindle nut being held on the housing on both sides. The double-sided mounting of the axis enables mechanically stable constructions.

The swivel drive described above and claimed in claim 36 can also be used in window systems other than the systems explained above and is accordingly of independent importance.

The invention will be explained in more detail below with reference to a drawing. Here shows:

The window of a building shown in Fig. 1 comprises a frame 1 arranged in a vertical plane and a wing frame 7 which can be rotated alternately about a lateral vertical axis 3 or tiltable about a lower horizontal axis 5 on the frame 1. For this purpose, the wing frame 7 is on a lower one Side corner mounted in a corner bearing 9, not shown, and is locked on the one hand on the frame 1 by an at least partially concealed drive rod arrangement 11 in a rebate circumferential surface of the sash frame 7 and on the other hand switched between the tilting operation and the rotating operation. The drive rod assembly 11 is moved in the circumferential direction via a drive rod gear, not shown, by means of a rotary handle 13, which is rotatably mounted on the axis of rotation 15 about the plane of the sash 7. The drive rod assembly 11 encircles essentially the entire casement 7 and is provided with a plurality of circumferentially distributed locking pins, two of which are shown at 14 and 15. When the window is closed and locked, the locking pins 14, 15 engage in striking plate pieces 17, 19 which are embedded in the inner fold surface of the frame 1. When the window is closed and locked, the rotary handle 13 assumes the position A shown in FIG. 1, from which it can be rotated into a tilt opening position C via a pivot opening position B. In the rotational opening position B, a locking pin 21 provided on the drive rod arrangement 11 locks an extension arm 25 attached to the frame 1 via a pivot bearing 23, in which the locking pin 21 engages in a counter member 27 of the opening arm 25. The wing frame 7 defined by the corner bearing and the swivel joint 23 can thus be rotated about the axis of rotation 3.

In the tilt opening position C, the locking pin 21 is extended from the counter member 21 of the extension arm 25 and the drive rod arrangement 11 has locked a tilt bearing 29 diagonally opposite the pivot bearing 23. The sash frame 7 guided on the extension arm 25 can thus be tilted about the tilt axis 5.

As far as described so far, the window is conventional. In addition, however, the window is provided with a locking drive 31 integrated in the rotary handle 13, which is explained in more detail below with reference to FIGS. 6 to 8 and, independently of the manual rotary adjustment of the rotary handle 13 in the position of the rotary handle 13 shown in FIG. 1, the drive rod arrangement 11 can drive between a drive rod position assigned to the locking position A into the drive rod position assigned to the tilt opening position C. Furthermore, a tilt drive 33 is arranged on the upper horizontal leg of the frame 1, which can be coupled to the drive rod arrangement 11 of the sash frame 7 via a pivotably driven scissor lever 35 and drives the sash frame 7 in the tilting direction in the tilt-open position of the drive rod arrangement 11 independently of the rotary handle 13. Details of the tilt drive are explained below with reference to FIGS. 9 to 11. The window further comprises at least one position sensor arrangement consisting of two mutually assigned sensor parts, which detect the locking position of the drive rod arrangement 11 and / or the closed or tilt-open position of the casement 7. Details of position sensor arrangements are explained below with reference to FIGS. 3 to 5.

For monitoring the locking and closing status and for controlling the locking and tilting drives of a plurality of windows 41 according to FIG. 1, microprocessors 43 are provided in close proximity to the windows 41, each of which either a single window 41 or a group of spatially adjacent, for example controls window 41 associated with the same room in the building. The microprocessors 43 are connected via connecting lines 45 to the position sensor arrangements, the locking drives and the tilt drives of the windows 41 assigned to them. The microprocessors 43 are in turn connected via a data ring line 47 to a remote monitoring center 49, in which the locking and closing status of the individual windows is indicated optically, so that the locking and closing status of all windows of the building can be monitored from a central location. The data ring line 47 can be the power network of the building, to which the microprocessors 43 as well as the monitoring center are coupled via data coupling stages. However, the data ring line 47 can also be formed by a line additionally laid in the building. A diode array 51 can be provided for the optical display of the locking and closing status of the windows 41, which indicates the locking and closing status by means of light-emitting diodes 53 for each individual window or for each group of windows. To display the closed and locked status on the one hand and the unlocked or opened status on the other hand, light-emitting diodes of different colors, such as green and red, can be used. The microprocessors 43 pass the locking and firing status information to the control unit 49 in succession, controlled by a controller 55 Monitoring center 49 from. The microprocessors 43 can be queried in the form of a cyclic time-division multiplex method; However, address codes for the identification of the microprocessors 43 and the windows 41 assigned to them can also be transmitted together with the status information. In the case of a large number of windows to be monitored in particular, the controller 55 is expediently a computer which can also take on additional control and monitoring measures, such as, for example, the central control of the windows 41 or a graphic representation of the locking and closing state of the Window via a monitor 57, which visually displays the status information of the windows in text form and / or in a graphical representation, including a floor plan of the building. The controller 55, which is designed as a computer, can also be used for remote data transmission via suitable interface circuits 59.

The locking and closing state of the windows 41 can be remotely controlled from the neighborhood without having to approach the window to be opened or closed. For this purpose, a remote control receiver 61 is connected to the microprocessor 43, which responds to a wireless remote control transmitter 63. The remote control transmitter 63, which is preferably an infrared transmitter, has control buttons for the status control of the windows 41 connected to the microprocessor 43. When the control command for opening one of the windows is sent, the microprocessor 43 first switches on the locking drive of the window in the unlocking direction to then control the tilt drive in the opening direction after unlocking the window. In response to a closing command First the tilt drive is controlled in the closing direction and then the locking drive is switched on in the locking direction. Both the locking drive and the toggle drive are provided with limit switches to which the microprocessor 43 responds in order to prevent the two drives from being switched on at the same time. Since the drives may have a comparatively long run-on time, it is advantageously provided that the microprocessor 43 short-circuits the electric motors of the drives via suitable output circuits when the limit switches of the drives respond and thus actively brakes electrically.

The microprocessors also monitor the level of the drive current of the electric motors. The nominal current of each electric motor that occurs during normal operation increases sharply when the motor is blocked. The microprocessor compares the current level with a predetermined current threshold value and generates a monitoring signal representing the blocking of the electric motor if the threshold value is exceeded. Controlled by the microprocessor 43, the monitoring center optically indicates the occurrence of the monitoring signal on the diode field 51 or the monitor 57 and triggers an alarm device if necessary. With the help of the current monitoring of the electric motors, not only unwanted blocking of the window can be detected, for example by an object jammed between the frame 1 and sash 7, but also attempts at sabotage in which the closing of the window is to be intentionally prevented. Since the motor current can occur in operation in individual cases even with only a brief inhibition, for example due to a stiff sash frame, the microprocessor 43 expediently also monitors the period of time within which the overcurrent occurs.

The monitoring signal representing the blocking state is only reported to the monitoring center 49 if it has occurred continuously during a predetermined time interval. False alarms can be avoided in this way. The microprocessor 43 also switches off the motor which is operated with overcurrent during the predetermined time interval and thus prevents damage to the motor from overloading.

The windows 41 can not only be controlled remotely from the neighborhood, but also via a central operating device 65 of the monitoring center 49. The operating device 65 is designed so that it allows both the specific control of individual windows by specifically selecting the assigned microprocessor 43 and also the collective control of groups of windows, for example a floor or a room, as well as the collective control of all windows in each case by pressing the special keys provided for this purpose. The microprocessors 43 are again addressed in accordance with the cyclical call scheme of the controller 55 or via address codes which are specifically assigned to the microprocessors or windows.

In addition or as an alternative to the local control of the microprocessors 43 by expediently transportable remote control transmitters 63, further remote control transmitters 67, in particular infrared transmitters, which are arranged in a fixed manner, can be provided, which have a sensor 69 which responds to a state parameter of the room air are connected and control the opening state of the windows connected to the associated microprocessor 43 depending on the detected value of the room air parameter. The sensor 69 is, for example, a sensor that detects the relative air humidity and opens the window when the value of the air humidity exceeds a predetermined threshold value. In this way, mold formation and the like can be avoided in rooms at risk of moisture. The window closes when the moisture falls below the threshold again. In order to introduce a hysteresis property of the control, the threshold value controlling the closing movement is preferably somewhat lower than the threshold value provided when the window is opened. Alternatively, however, additional sensors can also be provided which respond, for example, to the room temperature or the CO₂ content of the ambient air and ensure that the window is opened or closed automatically when predetermined values of the parameters are exceeded. As a further measure which increases the ease of use of the window system, it can be provided that the sensor 69 responds to the sound level outside the building, so that the window is closed automatically, for example in the event of road or aircraft noise. Finally, as a further comfort-increasing measure, a sensor 71, which responds to the flow velocity of the air in the area of a window, can be connected to the microprocessor or possibly the remote control transmitter 67, which controls the window depending on the draft.

3 to 5 show variants of position sensor arrangements as they can be used for monitoring the locking and closing status of a window according to FIG. 1 used in a system according to FIG. 2. Fig. 3 shows a corner deflection of a greenhouse gene arrangement with a faceplate angle 73, which is provided at its ends with connectors 75 for extension parts of faceplate 77. On the legs of the faceplate angle 73 are connecting pieces 79 for driving rods 81 movable in the circumferential direction of the casement 7, which are coupled to one another in the corner region of the faceplate angle 73 by a flexible steel band 83. The connecting pieces 79 carry locking pins 13, 15 for engaging in the striking plate pieces 17, 19 of the frame 1 in Fig. 1. The drive rods 81 and thus the locking pins 13, 15 are, corresponding to the positions A, B and C of the rotary handle 13 in Fig 1 is movable between a locking position A, a rotary opening position B and a tilt opening position C, both by turning the rotary handle 13 and via the locking drive 31. To detect the position, the locking pin 15 lying in the upper fold peripheral surface is covered, ie not visible , A permanent magnet 85 is provided which overlaps in the locked position A with a magnetic field sensitive sensor, for example a Hall switch 87, when the window is closed. The Hall switch 87 thus responds only when the window is closed and locked and does not respond when one of the two conditions is not met. The signals of the Hall switch 87 form the status information displayed by the monitoring center and are also used to control the locking drive 31 and the tilt drive 33 by means of the microprocessor 43.

FIG. 4 shows a variant of a position sensor arrangement which differs from the arrangement according to FIG. 3 only in the number and arrangement of its sensors. Identical components are with the 3 and to distinguish them with the letter a. For explanation, reference is made to the description of FIG. 3. In contrast to FIG. 3, the position sensor arrangement comprises a plurality of magnetic field sensors provided on the sash frame 7, via which both the locking position A and the tilt opening position C of the drive rods 81a and the closed position of the sash frame 7 can be detected separately. On the inside of the faceplate angle 73 and thus concealed, a first permanent magnet 89 is connected to the connecting rod connector 79, the position of which is detected by two Hall switches 91 and 93 in the locking position A on the one hand and the tilt opening position C on the other. The rotary opening position B can be monitored by a logical combination of the output signals of the Hall switches 91, 93. A second permanent magnet 95 is arranged on the frame 1 and is detected in the closed position of the window by a magnetically sensitive sensor, in particular a Hall switch 97. The signals of the Hall switches 91, 93 and 97 are evaluated in the assigned microprocessor 43 and transmitted to the monitoring center 49 (FIG. 2). A high degree of security against manipulation is achieved by the separate evaluation of the individual drive rod positions and the closed position of the casement.

5 shows a further position sensor arrangement with comparatively high manipulation security in the form of a plunger contact 101 arranged on the casement 7 similar to the sensor part 37 in FIG. 1 and having a mating contact part 103 as a second sensor part similar to the sensor part 39 in FIG. 1 in the rebate inner surface of the window frame 1 assigned. The tappet contact 101 is in the fold peripheral surface of the sash 7 by a faceplate rail 105 covered and exits through an opening 107 of the faceplate 105. The plunger contact 101 is held on a lever part 109, which in turn is pivotally mounted on a bearing block 111 which is fixedly connected to the faceplate 105 about an axis 113 extending approximately perpendicular to the plane of the sash 7. By pivoting the lever part 109 into the position indicated by dashed lines in FIG. 5, the plunger contact 101 can be withdrawn completely behind the faceplate 105.

The pivoting movement of the lever part 109 is controlled by a cam part 117 which is fixedly connected to a drive rod 115 of the drive rod arrangement 11 and which moves together with the control movement of the drive rod 115 along the lever part 109. In order to be able to control the lever part 109 non-positively in both pivoting directions, it is designed as a double-armed lever which carries the plunger contact 101 on one arm 119 and has a second arm 121 on the side of the axis 113 opposite the arm 119. The arms 119, 121 form cam tracks inclined at an obtuse angle to each other, against which the cam part 117 slidably abuts. 5 shows the locking position of the drive rod 115, in which the cam part rests on the arm 119 and presses the tappet contact through an opening 123 of the drive rod 115 and the opening 107 of the faceplate 105 against the mating contact 103. In the tilt-open position of the drive rod 115, the cam part 117 rests on the arm 121, as a result of which the arm 119 is folded back into a recess 125 in the casement 7. The displacement movement of the drive rod 115, which transfers the cam part 117 to the arm 121, at the same time brings the end edge 127, which is located in the direction of movement, over the opening 107 of the faceplate 105, with which both in the rotational opening position and the tilt opening position of the drive rod 115, the opening 107 of the faceplate 105 is covered by the drive rod 115. The plunger contact 101 is thus protected against manipulation in positions of the drive rod 115 which allow the window to be opened. Although the plunger contact 101 can have spring properties, spring properties of the plastic lever part 109 are expediently used. For this purpose, the arm 119 is provided with a recess 129 which weakens its cross section between the plunger contact 101 and the axis 113.

6 to 8 show details of the construction of the hand turning handle 13 from FIG. 1. The hand turning handle 13 comprises a base part 131 which can be screwed onto the casement 7 in the usual manner and on which a lever handle 135 is rotatably mounted about the axis 15 via a bushing 133 is. The lever handle 135 forms a housing for the locking drive 31, which consists of an electric motor 137, a spindle drive 139 and a rack and pinion gear 141. The spindle drive 139 has a threaded spindle 143 running in the longitudinal direction of the lever handle 135, which is driven by the electric motor 137 arranged coaxially. The threaded spindle 143 intersects the axis 15 and bears a spindle nut 147 on opposite housing walls 145 which cannot be rotated but is displaceably guided and to which a toothed rail 149 is fastened, for example screwed, parallel to the threaded spindle 143. The toothed rail which moves with the spindle nut 147 meshes with a pinion 151 which is seated in a rotationally fixed manner on the handle-side end of a square mandrel 153 which is coaxial with the axis of rotation 15. The square mandrel 153 rotatably engages in the drive rod arrangement 11 in a manner not shown in detail shifting drive rod gearbox. At the end of the lever handle 135 remote from the axis of rotation there is provided a finger button 155 which is displaceably guided on the lever handle 135 in the longitudinal direction thereof and is biased by a compression spring 157 with its locking projection 159 into a recess 161 of the base part 131. The finger button 155 forms a torque support for the reaction torque exerted by the electric motor 137 on the lever handle 135 when the mandrel 153 is driven. Since the spindle drive 139 has self-locking properties, the lever handle 135 can also be rotated manually with the mandrel 153 after the finger button 155 has been pressed and the locking projection 159 has been disengaged. The window can thus be locked and unlocked independently and in any position of the spindle drive, which is particularly important for emergencies.

In the two opposing end positions of the spindle nut 147, the spindle drive 139 is assigned two limit switches 163 for controlling the electric motor 137. The limit switches 163 are connected to the microprocessors 43 in the system according to FIG. 2. The microprocessor cannot use the limit switches 163 to control the electric motor 137, in particular for its active electrical braking, but also as a position sensor arrangement for monitoring the position of the drive rod arrangement, since the lever handle 135 locks in its rest position with the base part 131 when the drive rod arrangement is motorized is thus in a predetermined position. The connecting lines to the limit switches 163 and to the electric motor 137 are via resilient plunger contacts 165 in the region of the free end of the lever handle 135 remote from the axis of rotation of the lever handle 135 to the base part 131 led. As shown in FIG. 7, the plunger contacts 165 are arranged in two rows running essentially in the longitudinal direction of the lever handle 135 and offset from row to row, so that they move in different and not unintentionally contacting circular paths when the lever handle 135 rotates.

Due to the coaxial arrangement of the electric motor and spindle drive in the longitudinal direction of its lever handle, the hand-operated rotary handle 13 explained above has comparatively small dimensions. The toggle drive 33 shown in detail in FIGS. 9 to 11 also has similarly small dimensions. The toggle drive 33 has a two-part housing 167 with a rectangular cross section, which is inserted in a corner recess in the frame 1 on the front side and flush on the inside of the rebate surface. The housing 167, which is elongated in the circumferential direction of the frame 1, accommodates an electric motor 169 and a spindle drive 171 driven by the motor 169 coaxially alongside one another in the longitudinal direction. The spindle drive has a threaded spindle 173 which is driven by the motor 169 and on which a spindle nut 177 which is guided in a rotationally fixed but axially displaceable manner between opposite wall surfaces 175 of the housing 167 is seated. The scissor lever 35 is pivotably mounted outside the housing 167 on an axle pin 181 which is passed through a longitudinal slot 179 of the spindle nut 177 and is held in the housing 167 on both sides of the spindle nut 177. In the installed position, the axle pin 181 runs perpendicular to the longitudinal direction of the upper leg of the frame 1 and parallel to the plane of the frame 1. In the spindle nut 177, a further axle pin 183 is also held, which is held by a snap ring 185 is axially secured between the scissor lever 35 and the housing 167 (FIG. 11) and emerges from the housing 167 through an elongated hole 187 (FIG. 9) extending in the direction of displacement of the spindle nut 177 and engages in an elongated hole 189 extending along the scissor lever 35. The free end of the scissor lever 35 carries a mushroom pin 191 which, when the sash frame is tilted, engages in a guide rail 193 extending along the upper leg of the sash frame. The guide rail sits firmly on a drive rod 195 and, together with the mushroom pin 191, forms a travel compensation coupling, via which the pivoting movement of the scissor lever 35 driven by the motor 169 is converted into a tilting movement of the casement. The guide rail 193 has an essentially C-shaped cross section and accommodates the widening of the head of the mushroom bolt 191 in its guide channel.

The length and position of the guide rail 193 relative to the drive rod 195 is dimensioned such that the mushroom pin 191 lies outside the guide rail 193 both in the locking position and in the rotary opening position of the drive rod 195 when the scissor lever 35 in its window corresponding to the closed, parallel to Drive rod 195 extending position is, as shown in Fig. 10. In this position of the scissor lever 35 of the tilt drive 33, the drive rod 195 can be opened manually by manually actuating the rotary handle 13 (FIG. 1) into the rotary opening position B, for example in the event of a defect in the tilt drive or in emergencies. If the window is to be tilted by a motor, the drive rod 195 is moved by means of the locking drive 31 into the tilt opening position in which the guide rail 193 engages the mushroom pin 191.

The spindle drive 171 is in turn assigned two limit switches 197 which can be actuated by the spindle nut 177 and which are connected in a manner not shown in detail via connecting lines to the assigned microprocessor 43 (FIG. 2). The microprocessor 43 controls the operation of the electric motor 169 as a function of the actuation of the limit switches 197 and in particular as a function of the limit switches 197 controls the electrically active braking operation of the motor. In addition, the two limit switches 197 can also be used here as position sensors for the tilting position of the casement.

The housing 167 of the tilt drive 33 is fastened in the recess of the frame 1 by means of a mounting flange 199 which is integrally formed on the housing 167. The fastening flange 199 is arranged symmetrically in the axial direction of the axle bolts 181, 183, and the axle bolts are arranged on the housing 167 in such a way that they can be plugged over. The tilt drive 33 can thus be used equally for left- or right-hinged windows.

For some applications, windows should be able to be blocked so that at least they cannot be opened via the locally assigned remote control. In the system according to FIG. 2, it is provided that the microprocessors 43 of the individual windows 41 or the window groups assigned to the microprocessors 43 can be selectively or group-wise blocked altogether via the operating device 65 of the monitoring center 49, so that they can control commands that they cannot reach from remote control receivers 61 or other control devices. The blocking commands are expediently coupled with closing and locking commands, so that the blocking in the closed and locked state of the windows he follows. The purely electrical blocking of the electrical window actuation has the advantage that the windows can still be opened manually in emergency situations.

FIG. 12 shows a variant which, in addition or optionally also as an alternative to the electrical blocking explained above, permits mechanical blocking of the drive rod arrangement 11 (FIG. 1). The blocking device according to FIG. 12 comprises a support part 205, not shown in detail at 201 with a faceplate 203 of the drive rod arrangement, on which an angle pawl 207 is pivotally mounted about an axis 209 running perpendicular to the plane of the sash frame 7. The angle pawl 207 has a pawl arm 211 which projects from the axis 209 substantially parallel to a drive rod 213 of the drive rod arrangement against the opening movement direction (arrow 215) of the drive rod 213. A recess 217 is provided in the drive rod 213 at a point corresponding to the latch arm 211 in the locked position of the drive rod 213, into which the latch arm 211 is pretensioned by a compression spring 219 held on the supporting part 205, as is shown by a dash-dotted contour in FIG 12 is indicated. The pawl arm 211 thus automatically blocks the drive rod 215 in its locked position and must be actively moved out of the locked position for the unlocking process and for switching the locking fitting into the rotary opening position or the tilt opening position. To unlock the blocking device, an electromagnet 221 is provided on the support part 205, the armature plunger 223 of which is displaceably mounted parallel to the drive rod 215 and the angled pawl 207 via its actuating element running at right angles to the pawl arm 211 arm 225 swings against the force of the spring 219. The electromagnet 221 is excited via the microprocessors 43 (FIG. 2) together with the locking drive. If the microprocessors 43 are electrically blocked via the operating device so that they cannot execute local commands, the electromagnet 221 is not energized and the drive rod arrangement of the window is also blocked against manual unlocking. In order to still be able to open the window manually in the case of non-blocked microprocessors, 13 switching contacts can be provided on the rotary handle, for example, which close the excitation circuit of the electromagnet 221 when the locking fitting is operated manually.
