Description

The invention relates to a door or window arrangement comprising a window frame and at least one sash frame movably connected thereto, the sash frame having a locking bar which is slidably guided in a fitting groove of the sash frame and on which at least one locking pin is arranged, which engages with at least one locking pin receiving element on the window frame stands or at least can be engaged. The displaceably guided locking bar can be driven, for example, with a manual control element. Such a manual control element can be permanently arranged on the casement. However, it can also be arranged on the casement so that it can be temporarily attached and removed again, e.g. via a plug-in connection.

In arrangements of this type, the casement frames and/or blind frames can be made, for example, from plastic profiles, in particular with a reinforcing steel insert, from wooden profiles, from metal profiles, preferably from aluminum profiles, and also from composite profiles, i.e. profiles made from two different materials, such as wood and Aluminum.

A door or window assembly of this type is well known in the art. The frame is understood to be the frame that is usually firmly connected to a component of a property, such as the masonry or a stud frame. Such a window frame is usually composed of several, in particular identical, window frame profiles that are connected in the corner areas.

The sash frame is the frame that can be moved relative to the fixed window frame, which usually includes the glazing and which is also formed from a plurality of, in particular identical, sash frame profiles connected at the corners.

The wing frame is often, preferably also in the invention described here, pivotable about two mutually perpendicular axes of rotation. An axis of rotation, in particular the vertical one, is the axis about which the casement can be opened completely, in particular greater than 90 degrees to the frame. Another axis of rotation, in particular the horizontal one, is the axis of rotation about which the casement can be brought into a tilted position relative to the window frame by a limited angular range, in particular less than 45 degrees.

With such an arrangement, for example, 3 functions can be implemented, in particular the function in which the sash frame is immovably locked to the window frame (closed function), the function in which the sash frame can be opened relative to the window frame (open function) and the function in which the sash frame can be tilted in relation to the window frame (tilt function).

The invention is used in such door or window assemblies which have these three functions.

The realization of the functions that are possible between the sash frame and the window frame results from the fitting elements in the arrangement. These include, for example, hinge elements, locking rods, locking pins, locking pin receiving elements (locking plates), manual control elements such as handles (olive), power transmission elements, scissor linkages, etc. A Arrangement of the invention can include several of these elements, but does not necessarily have to include all of the elements mentioned.

The casement according to the invention comprises at least one locking bar that is displaceably guided in a fitting groove of the casement. Such a locking bar can, for example, be driven in a known manner with a manual control element. The manual control element can drive the locking bar directly or, in the majority of cases, indirectly via power transmission elements, e.g. if the manual control element is arranged on a vertically aligned casement profile of the casement, while the driven locking bar is arranged in a horizontal casement profile of the casement.

The at least one locking bar is arranged at least in the horizontal lower casement profile of the casement, ie in a horizontal fitting groove.

In this arrangement, the fitting groove is located on the underside of the casement profile. In particular, the fitting groove is generally open to the opposite frame profile of the frame. Several locking bars can be slidably guided in mutually perpendicular orientation in respective fitting grooves of the casement profiles. Preferably, these are then kinematically connected in the corners of the frame, e.g. by force transmission elements, which can be designed as flexible push/pull straps, for example, so that the actuation of one of the locking bars, e.g. with a manual control element, is transferred to the at least one other locking bar coupled .

The at least one locking pin on the at least one locking bar protrudes from the latter in the direction of the opposite frame profile of the window frame and can engage with at least one locking pin receiving element or a locking plate, which is fastened to the window frame, on the lower horizontal window frame profile of the window frame, or at least in intervention.

The possible functions of the arrangement are defined by the relative position of the at least one locking pin to the at least one locking pin receiving element, possibly also by further elements. These possible relative positions can be adjusted by shifting the locking rod carrying the at least one locking pin relative to the at least one locking pin receptacle fixed on the window frame, e.g. by operating a manual control element.

A locking pin can, for example, only be operatively connected to one locking pin receptacle, in which all functions can be set by repositioning the locking pin in this locking pin receptacle, or with two locking pin receptacles spaced apart in the possible direction of displacement of the locking bar, each of which is assigned a different function, e.g the closed function and one for the tilting function.

Usually, doors or windows are manually switched from the closed function to the open function or tilting function and back by operating a manual control element, such as a handle.

the DE 101 13 784 discloses, for example, a window or door assembly in which a movably mounted sash is provided in a frame which can be moved to different positions relative to the frame by control movements. A large number of fitting modules are provided for this purpose, which fulfill the individual holding and movement functions.

There are also automatic fittings that use electric motors to open or close windows in a tilted position. Such windows can also be secured via motor-operated locking elements. For example, it is known to arrange drive units on the outside of the window frame or on the outside of the casement, with which a relative movement can be generated between them, for example by chain drives.

Such drive units are visually unattractive and often have to be wired in a visually recognizable manner.

Although these designs have the advantage of inhibiting the movement in the drive so that no separate locking function has to be implemented in this case, this also results in the disadvantage that manual actuation is not possible. The opening movement is also usually limited to the tilted position. It is not possible to open the window or door by turning it around a vertical axis.

In the case of automatically controlled windows/doors, it is generally disadvantageous that the closed or tilted position does not readily permit manual intervention. In the event of a power failure, for example, the window or door cannot be operated by hand. The sequence cycles of an automated control must first be terminated or deactivated when the power is supplied in order to allow manual operation.

Even with a proper power supply of fully automated large window fronts, as they are useful and wanted in large office buildings in normal operation and here only the change from closing and tilting position is necessary, switching to manual operation is often desired, e.g. to open a window to carry out cleaning work to open..

In the event of a fire, windows must also be able to be opened wide manually if necessary in order to rescue people from the outside.

The disabling and switching off of the electronics or the decoupling of the mechanical power transmission between the casement frame and the frame has hitherto been associated with an additional, not inconsiderable effort, for example by switching with a key card. The arrangement of drive units in the casement is also disadvantageous. The cramped space leaves little constructive leeway for accommodating motor units, so that these, as mentioned above, are often placed on the outside. power supply cable must be routed via a bridge into the casement frame, which often leads to susceptibility to failure.

Door or window assemblies with electromotive drive units are from the publications EP 1 580 369 A2 , EP 2 642 050 A2 , EP2 799 647 A1 , EP 3 034 749 A1 and DE 202 04 224 U1 known. At least the EP 1 580 369 A2 discloses an arrangement according to the preamble of claim 1.

It is therefore the object of the present invention to create an automated door or window arrangement of the type mentioned at the outset, which on the one hand is visually attractive, the drive unit is preferably not recognizable when the arrangement is closed, and on the other hand a visually unrecognizable routing of cable leads to the power supply from electric motors, e.g. from the surrounding masonry.

A further object of the invention is preferably to be able to switch an arrangement of the type mentioned at the outset manually or by motor between at least two functions, such as the closed and tilting function, preferably between three functions (closed, open, tilting function). to be able to, most preferably without any action required by the user.

This object is achieved according to the invention by a door or window arrangement comprising a window frame and at least one sash frame movably connected thereto, the sash frame having a locking bar which is guided in a fitting groove in the lower horizontal casement and can be driven in particular with a hand-operated locking bar, on which at least one locking pin is arranged, which engages or can at least be brought into engagement with at least one locking pin receiving element on the lower horizontal window frame and the casement frame can be opened completely about a vertical axis of rotation and can be brought into a tilted position relative to the window frame about a lower horizontal axis of rotation by a limited angular range, wherein a function is defined by the relative position of the at least one locking pin to the at least one locking pin receiving element, in which the casement is immovably locked to the frame, ei ne function is defined in which the sash frame can be opened relative to the frame and a function is defined in which the sash frame can be tilted relative to the frame, the functions being achieved by shifting the locking rod carrying the at least one locking pin relative to the at least one locking pin receiving element stationary on the frame are adjustable and wherein a drive unit is arranged in the frame, which has a drive motor and has a driver that can be moved by this in the direction of displacement of the locking bar and at least one driving pin is arranged on the locking bar, which engages with the driver or at least can be brought into engagement, characterized in that the drive unit is arranged in the lower horizontal frame profile, which is parallel and close to the axis about which the casement can be tilted, and the direction of displacement of the locking bar and the direction of displacement of the driver is parallel to the extension of the axis about which the casement can be brought into a tilted position relative to the window frame, and the driver two spaced drive surfaces facing each other, between which the driver pin is arranged and forms a longitudinally extending recess in the displacement direction of the locking bar with the drive surfaces for receiving the driver pin, which has an opening open in the opening direction of the casement has, through which the driver pin can enter and exit the recess, the driver having exactly the same functionality in relation to the driver pin as the locking pin receiving element in relation to the locking pin.

Due to the arrangement in the window frame, the drive unit is optically unobtrusive, in particular only visible when the window frame is open, and it can be wired through the window frame, e.g. through hollow chambers that run parallel and separately from the hollow chamber, in which a reinforcement profile is integrated.

Said driver of the drive unit can be moved back and forth by means of the drive motor in the direction which corresponds to the direction in which the locking bar is slidable in the fitting groove. The driver pin, which is arranged at a distance from the locking pin on the locking bar in the displacement direction, can thus be moved by the driver, in particular in that the driver takes the driver pin with it in its direction of movement, the movement being transmitted to the locking bar and its locking pin that motorized the various possible functions can be adjusted by the different relative positions between the locking pin and locking pin receptacle.

A driver within the meaning of the invention is thus to be understood in general as an element which is set up to entrain the at least one driver pin when the driver moves in the same direction. This "carrying" takes place in that the said engagement between the driver and the at least one driver pin represents an operative connection in which the driver and the at least one driver pin are non-positively connected, so that the movement of the driver causes an on the engaged driver pin acting force is generated, which leads to the movement of the driving pin in the same direction. The driver has several drive surfaces that at a Movement of the driver with the at least one driver pin are in contact.

The drive unit can preferably be designed identically for different types of door or window arrangements. This opens up the advantage that different fitting types of a door or window arrangement can be operated with a universally usable drive unit. All combinations with commercially available fittings are conceivable here. This also opens up the possibility of retrofitting existing door or window arrangements. In particular, there is compatibility because the driver is designed like a conventional fitting, in particular like a conventional locking pin receptacle, in particular like a striking plate. The drive unit is preferably compatible with existing window systems in terms of reinforcing steel, seals and glazing beads. Conventional processing with all static properties in an unchanged external appearance can preferably be implemented.

In a preferred embodiment, at least the drive motor of the drive unit is arranged in a cavity under the rebate surface of the window frame, in particular in a cavity which is arranged in the closing direction of the casement in front of a cavity in which a reinforcement profile of the window frame is accommodated, preferably in the rebate surface A recess is arranged in the window frame, through which the drive motor is inserted into the cavity. For example, the cables for power supply and/or signal transmission can also be routed in the same cavity, which preferably extends along the entire frame profile. The cables can be routed out of the frame in a corner area, for example.

In existing door or window arrangements, a recess can be made in the rebate surface, e.g. subsequently, and the drive unit can be at least partially inserted into the cavity thus opened, in particular at least with the drive motor.

A preferred construction can provide here that the drive unit has a mounting plate, under which the drive motor is arranged and above which the driver is arranged, with a recess in the rebate surface of the window frame being covered, in particular sealed, with the mounting plate. Such a mounting plate can have a guide projection on its underside, which can be inserted into a groove of the window frame, for example in the glazing bead groove of the window frame. Such a guide projection can be arranged on the underside on the longitudinal edge of the mounting plate and can preferably extend over the entire length of the mounting plate. In this way, the drive unit can be precisely positioned in the depth direction of a window frame. The drive unit can be screwed through the mounting plate into the window frame profile with screws, in particular without having to penetrate into the reinforcement profile or its cavity. It can also be provided that the drive unit is screwed to the reinforcement profile.

The mounting plate preferably has a slot which extends in the displacement direction of the driver and in which the driver is arranged so that it can be displaced and which can be moved back and forth by the drive motor underneath.

For the motorized displacement of the driver, the invention can preferably provide that the drive unit has a threaded spindle driven by the drive motor, which extends in the direction of displacement of the locking bar, in particular parallel to it, the driver being designed as a spindle nut on the underside or having a spindle nut, in which the threaded spindle lies. The underside area of the driver is understood to be an area of the driver that lies under the mounting plate and thus in the window frame. A top area of the driver, which is thus located above the mounting plate, is in operative connection with at least one driver pin.

The driver of the drive unit or at least the area thereof which is in operative connection with the at least one driver pin, in particular the area which contacts the at least one driver pin in a driving manner, e.g surrounds can be arranged so preferably in an area between the rebate surface of the frame and the locking bar of the casement. It is thus located in an area which is also provided for the interaction of the locking pin and the locking pin receiving element. According to a preferred embodiment of the invention, the drive unit, in particular comprising the drive motor with driven threaded spindle, driver and mounting plate, is formed in an area of a lower edge of a window frame, for example in a window frame.

The invention provides that the driver has a freewheeling area around the driver pin, in particular around the only driver pin assigned to this driver, i.e. at least in some positions of the driver, it does not move the driver pin directly during its movement, but only after the freewheeling area has been covered. According to the invention, the driver also has exactly the same functionality in relation to the driver pin as the locking pin receiving element in relation to the locking pin.

For this purpose, in one embodiment, the driver can have a recess for receiving the driver pin, which is in the Shape is identical to the recess of the locking pin receiving element for receiving the locking pin, in particular, the driver pin can also be designed identically to the locking pin. In particular, this can be provided if one, in particular a single, locking pin receptacle is provided on a frame profile of the frame, with which all functions of the casement can be implemented, ie closed, open and tilting function. For example, a duplicate of the locking pin receptacle can be used as a driver by providing it with a spindle nut on the underside, through which the aforementioned spindle of the drive motor can pass in order to move this locking pin receptacle.

The elongate recess of the driver can be designed, for example, as an elongated hole extending in the direction of displacement of the locking bar. The elongate recess, in particular the elongated hole, has an opening in the wall of the recess that is open in the opening direction of the casement, through which the driver pin can pass, i.e. can step out of the recess and also re-enter the recess when opening and closing the casement relative to the frame around the vertical axis. The opening is preferably arranged centrally in the recess with respect to the length of the recess/long hole, but can also be arranged off-center. The breakthrough width is greater than or equal to the tang width.

An elongate recess can in principle have any elongate cross-sectional shape into which the driver pin fits in a longitudinally displaceable manner. The elongated one Recess can thus be formed, for example, with an angular internal cross section. Designing the elongated recess as an elongated hole is preferably understood to mean that it is formed on the basis of a circular cross section, so in particular the cross section of the elongated hole recess can correspond to a circular cross section shifted in the longitudinal direction. This circular cross-section is greater than or equal to the circular cross-section of the driving pin. This elongated hole design can, for example, be identical in terms of the internal cross-sectional shape to the locking pin receiving element, as previously mentioned.

An arrangement can be formed in which two locking pin receiving elements are arranged on the window frame in terms of functionality, one of which is fixedly connected to the window frame and the second locking pin receiving element is displaceable because it is namely formed by said driver. Thus, according to the invention, the driver has at least exactly the same functionality as the locking pin receiving element compared to the locking pin in relation to the driving pin, with the driver even being able to be formed by exactly the same locking pin receiving element (duplicate design) as previously mentioned.

All driving movements that act on the locking rod and put it into a pushing movement, originate in the invention alternatively from the driven driver or from the manual control element. In the case of the motorized drive variant, the movement is transmitted via the driver pin and the locking bar to the locking pin, and in the case of the manual drive variant, the force-fit coupling of the manual control element and the locking bar to the locking pin takes place.

In a drivingly coupled state, ie when the driver pin rests in the recess, the driver has two drive surfaces facing one another, which interact with the in particular single driver pin for force transmission. These driving surfaces are spaced in the direction of displacement. In the elongate recess, these drive surfaces are formed by the recess ends spaced apart in the displacement direction.

A basic position can preferably be provided in the drive unit for the driver, from which the driver can be displaced in both opposite directions. Provision can then be made for the driver to be displaceable from this basic position in both possible displacement directions by the stated distance between the functions or more. In the basic position, the driver is preferably arranged overall in the middle of the overall displacement path.

The invention can thus preferably make it possible for the position of the locking pin relative to the opening in the recess of the locking pin receiving element to be identical to the position of the driving pin relative to the opening in the recess of the locking bar when the locking bar is manually actuated in the basic position with a hand-held operating element Driver or a position, preferably the middle position between the two spaced drive surfaces. If the driver is in the home position, the function can also be adjusted manually at any time, e.g. by operating the manual control element/handle on the casement frame.

In the described embodiment of the driver with an elongated hole-shaped recess based on a circular cross-section, which has an opening on the long side, preferably a central opening, the inner surfaces of the elongated hole that are spaced apart in the direction of displacement form forks, which form the drive surfaces mentioned, which are Contact encircle the driving pin, eg by 180 degrees. By a lateral displacement of the driver in the direction of displacement Locking rod can either one or the other inner surface of the recess of the driver are brought into contact with the driving pin to this - and thus also the locking bar - can also be moved.

The length of the elongated hole, measured between the center points of the circles at the ends, i.e. the section of the driver connecting the forks, defines the path that the driver must cover in order to get from a coupling of the driver pin to one of the drive surfaces to a coupling to the other drive surface when the driver travels back the same distance after completing this route. The section connecting the forks thus defines a kind of "idling" between two drivingly coupled states in which a process of the driver is transmitted via the corresponding drive surface to the drive pin and thus ultimately to the locking rod.

The invention can now preferably further provide that it comprises a control unit for controlling the drive unit, with which the driver of the drive unit, in particular at the request of a user or programming, can be moved out of a basic position in one of two directions in order to achieve one of at least two functional positions of the locking pin relative to the locking pin receiving element.

In a further preference, the control unit can be set up, after the respective functional position has been reached, to control the motor in such a way that the driver is automatically moved back into the basic position. Alternatively, the functionality of automatically moving the driver back into the basic position after reaching the respective functional position can also be implemented in the drive unit itself be, in particular in such a way that no external command by a control unit is required for the return movement to the basic position.

The drive unit can be assigned an internal or external controller in the form of a wired or wireless control unit, which is designed in such a way that the driver can be moved to a left position, to a right position, and in particular to a basic position, with the basic position preferably being between the left and the right position. A control unit can, for example, be operable by means of a remote control, which can also be implemented by a mobile phone, for example.

A program cycle of the control unit or the drive unit itself is preferably designed in such a way that the driver always moves automatically from the respective stop position back into the central basic position. Only then is the automatic program run complete and manual operation of the window is possible. After returning to the basic position, the window can be closed or opened from the motor-assisted tilting position by manually operating the handle.

This also applies to the motor-assisted locking position. As soon as the driver has returned to the basic position, the window can be opened manually with the manual control element, in particular because the driver pin, which is then moved by the manual control element, can move freely in the elongated recess of the driver just as the locking pin can move relative to the Latch pin receiving element.

Without this reset to the basic position, manual intervention would only be possible after cumbersome shutdown scenarios.

The driver can be coupled to the locking bar in such a way that moving the driver to the left position causes the locking bar to be moved to the left (first) functional position and that moving the

Driver in the right position causes a shifting of the locking bar in the right (second) functional position. The locking bar can also be brought into a third functional position, which is between the left and the right functional position. It is particularly advantageous if the locking bar and the driver are designed in such a way that the locking bar can be brought into the third functional position by actuating the manual actuating device (handle) without the driver being involved. This means that the locking bar can also and in particular only be brought into the third functional position without the involvement of the drive motor.

According to a preferred embodiment, the left functional position of the locking bar defines a locking position of the arrangement in which the casement is locked in the window frame. In this embodiment, the right functional position defines a tilted position of the arrangement in which the sash frame can be tilted in the window frame. The third functional position defines 2. a rotational position of the arrangement in which the sash frame can be moved in the window frame by rotating it, ie it can be opened by rotating it in the usual way.

In one possible embodiment, the elongated hole within the driver has a length of 36 mm, for example.

The length of the extent of movement that the locking and driver pins require from the left to the right functional position, i.e. from the infeed via the rotary position to the tilting position, corresponds to the length (between the end circle centers) of the slot-shaped recess of the locking pin receiving element for the locking pin , so in this example 36 mm. This distance is traveled to the right to go from the closed to the tipped position and correspondingly back to reach the closed position from the tipped position. In order to ensure these travel distances for the driver pin, a total range of movement of the driver in the drive unit of at least 72 mm is required in this example.

Due to the structural design of the driver in the form of a fork in the elongated hole design, the driver pin is fully guided and secured. As a result of this configuration, the locking bar cannot subsequently perform any unintentional movements. The driver fulfills a double function.

On the one hand, it offers the driver pin the space to engage, pulls it into the desired position and forwards the movement to the locking bar. On the other hand, the driver fulfills a blocking function due to its structural design and no blocking rail is required. Operating errors are mechanically ruled out, since the locking pin or the driver pin are held by the locking pin receptacle or the driver.

A tilting device can be provided in order to be able to bring the casement into a tilted position and back again in a comfortable and reliable manner relative to the window frame—in particular automatically and/or remotely controlled—in all possible designs. The tilting device is directly or indirectly coupled to the drive motor and/or the manual actuating device (handle) in a drive-effective manner, in particular by mechanical forced guidance.

In particular, the locking bar can be a component of this coupling. The mechanical restraint causes an actuation of the drive motor or the actuating device not only to a movement of the locking rod, but also that a tilting movement of the casement, in particular thus a partial opening of the casement is generated. The design of the forced guidance ensures, by means of mechanically interacting components, that only the desired movement--ie tilting of the casement from a closed position into a tilted position and back--can be carried out. This is realized, for example, by a force-controlled standard scissor fitting. In a preferred embodiment, the effect of such a forcibly guided tilting device can be designed so that it can be switched on or off as desired, for example in that the tilting device can be detachably coupled to the locking bar or an element driven by it or that the tilting device performs an idle stroke. The driver of the drive unit can also run an "idle stroke" without causing the automatic tilt opening, in particular even if such is usually provided.

The invention is explained in more detail below with reference to the drawings.

Figures 3 - 6 show part of a functional mechanism of a fitting for doors, windows or the like, which are operated manually by means of a manual control element, for example a handle. The position of the driver pin 14 in the driver 23 is analogous to the position of the locking pin 13 in the locking pin receiving element 26. In this embodiment, the two pins move from the closed position, through the rotary to the tilt position, a distance of, for example, a total of 36 mm within the recording elements. The driver 23 stands still during the manual actuation.

the figure 1 shows a drive unit in the mounted state in the frame 20 together with the casement 10 in section. The drive motor 21 is located in a cavity 28 of the window frame 20. This cavity 28 is located in the closing direction in front of the cavity with the reinforcement profile. The cables to the drive unit can also be routed through the cavity 28 . The drive motor drives the driver 23 via a threaded spindle 22 on what Figure 2a further clarified. In the fitting groove 15, the locking bar 12 is arranged. This has a driver pin 14 which engages in the recess of the driver 23 .

figure 2 shows the lower frame profile of the frame 20 with a built-in drive unit, which has the driver 23. The motor 21 is immersed in a prepared cavity inside the window frame 20 and is located under a mounting plate 31 which forms a projection of the recess in the rebate surface of the window frame 20 and the cavity 28 seals against the ingress of water. The motor 21 is fixed in the frame with the mounting plate 31 hanging from the frame rebate surface 30 . The power supply cables 32 lead through the cavity 28, which serves as a cable duct, to the motor 21.

According to Figure 2a the driver 23 is driven directly by the drive motor 21 via a threaded spindle 22 . The stroke of the driver 23, measured from the outer left boundary edge to the outer right boundary edge, can correspond to the total distance that is required to move the locking pin 13 (shown in Figs Figures 3 ff) switch between two functions, in particular between the closed position and the tilted position of the casement. For example, the entire displacement path of the driver 23 can be 72 mm.

The driver 23 is with its upper part on the Figure 2a Mounting plate 31, not shown, into which the driving pin 14 engages. The lower area of the driver 23 is designed as a spindle nut, lies under the mounting plate 32 and is penetrated by the spindle 22 .

The total displacement path of the driver 23 can be seen from the movement slot 24 in the housing of the drive motor and the spindle 22 . In the Figure 2a the driver is arranged in the middle of the total displacement path, which corresponds to its basic position.

The driver 23 has a longitudinally extended recess 23a which is open at the top towards the casement frame and is designed here as a slot. The length of the elongated hole 23a is selected here so that the driver 23 can move freely around the driver pin 14 (not shown here) without entraining the driver in the movement until it rests against the drive walls 23b of the elongated hole, which are spaced apart in the direction of displacement. This free range of movement is at least as large or exactly as large as the distance between the positions of the locking pin 13, which is not shown here (see 3 ff) between the closed and the tilted position.

The tang 14 is preferably circular in cross-section and is surrounded by the drive walls 23b of the slot 23a 180 degrees upon contact. The elongated hole 23a also has an opening 23c, here in the middle of the long side of the elongated hole 23a, which lies in the opening direction of the casement. The opening 23c is at least as wide as the diameter of the driver pin 14, so that it can pass through the opening 23c when opening the casement 10, especially when the driver 23 is in its basic position in the middle of its total displacement path.

In principle, the recess 23a of the driver 23 could also be designed with an angular cross section and have the same length.

figure 3 shows the manual functional status of the window in the closed and locked position. The handle is (not shown here) vertically downwards. The locking pin 13 on the locking bar 12 is in the locked position in the locking pin receiving element 26, which is essentially to be referred to as a locking plate. The driver is in the home position and the motor 21 is off. The way to the ajar state in the Tilted position or in the tilted wide open position is possible. The handle can be turned into the horizontal position, the open position, for example.

figure 4 shows the manual operating mechanism of the window in the ajar, unlocked, open position. The handle is horizontal. The locking pin 13 in the locking pin receiving element 26 and the driving pin 14 have been shifted to the right by the manually driven locking bar 12, for example by 18 mm, and are in the rotary position in order to be able to open the window. The driver 23 is in the home position and the motor 21 is off. The path to the tilt state to the right, with handle up rotation, or back to the closed window setting, with handle down rotation, are possible. Due to the position of the driver 23 in the basic position, it does not impede the movement of the driver pin 14 corresponding to the locking pin 13 . The locking pin 12 and driver pin 14 thus move relative to their associated fitting elements, ie to the locking pin receiving element 26 or to the driver 23 in the same way.

figure 5 shows the manual operating mechanism of the window in the tilted position. The handle is up. The locking pin 13 in the locking pin receiving element 26 and the driver pin 14 have been moved further to the right by the manually driven locking bar 12, for example by a further 18 mm, and are in the tilted position. From the closed position to the tilted position, the pins have covered their maximum path, eg 36 mm. The driver 23 is in the home position and the motor 21 is off. The way back to the turning position for leaning or opening wide is possible by turning the handle horizontally.

figure 6 shows the manual functional status of the window again in the closed and locked position, such as figure 3 . The handle is pointing straight down. The locking pin 13 and the driving pin 14 have been moved back by the manually driven locking bar 12, for example by 36 mm to the left. The driver is in the basic position and the motor 21 is out. The path to the leaning position in the swivel position or in the wide open position is possible. The handle can be turned to the horizontal position accordingly. (cf. 3 )

the Figures 7 - 13 show the door or window arrangement according to the invention in automated operation using a drive motor 21 of the drive unit. In contrast to manual operation using a handle, the motorized drive 21 now takes over the drive of the locking bar 12. The driver 23 and the driver pin 14 located therein act as a force-transmitting element The driver 23 triggers the programmed direction of movement, for example, which is then passed on to the engaging driver pin 14 and subsequently pulls it along with the locking rod 12 and the functional positions of the window are realized from the closed to the tilted position.

A special feature of this embodiment according to the invention is that as the last step of the program cycle--that is, when the tilted position has been reached--the driver 23 is automatically reset to the basic position. While the driver 23 moves back, the window remains unchanged in the tilted position, in particular since it is locked against other movements during the moving back by the position of the locking pin 13 in the locking pin receiving element. Returning the driver 23 to the basic position has the effect that the driver pin 14 that has been pulled along has been held and pulled with its left stop surface in the left stop surface 23b of the driver fork. The driver pin 14 with the locking bar 12 remains in this position, the window is tilted and only the driver 23 moves by the length of the slot-shaped recess 23a, for example 36 mm here, for example, to the left. Thus, at the end of this process, the driver pin 14 lies with its right contact surface in the right stop surface 23b of the right fork of the driver 23. The program sequence ends here, the drive motor 21 switches off in this position and the position of the driver pin 14 in the driver 23 is made possible manual operation of the window with the handle.

Correspondingly, the described resetting of the driver 23 takes place when the driver 23 is reached from the tilted position to the closed position with the aid of a motor. Here the driver 23 performs the reset as the final program step, e.g. by 36 mm to the right. The window has been closed under motor control, by returning the driver 23 to the basic position and the associated change in the stop surface 23b of the driver pin 14 within the driver 23, manual operation can now be carried out using the handle 11 in the turn and open position.

figure 7 shows the motor-supported functional status of the window in the closed but still locked position. The handle, for example, is usually straight down. The locking pin 13 is located in the locking pin receiving element 26 in the left closed position. The motor 21 is switched on, the driver 23 moves to the right and takes the driver pin 14 directly from the basic position to the right. The program cycle starts with the goal of the tipping state. The handle is also rotated automatically to the horizontal position as a result of the shifting of the locking bar 12.

With the function shown in figure 7 the program cycle is started and in figure 10 the program cycle is stopped.

The program cycle is ended by returning the driver 23 to the basic position. When the home position is reached, manual operation of the window using the handle is possible at any time and the operator can move the handle of the window to any desired position and manually move the window to all possible functional positions. (p. figure 5 )

figure 8 shows the motor-assisted functional state of the window in the open rotary position with regard to the position of the locking pin in its receiving element, but is still kept closed due to the position of driver 23 and driver pin 14. The handle is horizontal. The locking pin 13 is located in the locking pin receiving element 26 in the rotary position. The motor 21 is switched on, the driver moves even further, for example by 18 mm to the right and, in the example, takes the driver pin 14 further to the right. The program cycle is on the way to the tipping state. The handle will automatically rotate upwards as a result of the latch bar 12 shifting to the vertical position.

figure 9 shows the motor-assisted functional status of the window in the tilt position. An automatic opening that may be desired can be implemented, for example, by a force-controlled scissor fitting, not shown here. The driver 23 moves only the driver pin 14. The handle is now vertically upwards. The locking pin 13 is located in

Latch pin receiving member 26 in the tilted position. The motor 21 is switched on, the driver 23 has moved to the right as far as it will go and taken the driver pin 14 out of the basic position to the right. In this position, the driver 23 has covered its maximum stroke, e.g. 36 mm to the right. The program cycle has reached the tipping state. The handle has automatically rotated upwards to the vertical position as a result of the displacement of the locking bar 12.

At the same time, in this constellation, both the locking pin 13 in the locking pin receiving element 26 and the driving pin 14 in the driver 23 are in a position which enables the tilt position, but are positioned oppositely in their respective associated fitting elements. When the window is tilted, both pins are held in the locked position and thus secured.

figure 10 shows the motor-assisted functional status of the window in the tilt position. The window is tilted. The handle still stands vertically upwards. The locking pin 13 is in the locking pin receiving element 26 in the tilted position as in FIG figure 9 . The motor 21 is switched on and the program cycle has in figure 10 executed the last phase and moved the driver 23 back to the home position. The driving pin 14 stands still. The locking bar 12 does not shift in this scenario. The handle makes no movement. The window is still in the tilted position and in the basic position also reaches a locked state by securing the two pins, although both pins are now positioned in the same way in their respective associated fitting elements. For this reason, manual actuation using the handle can also now take place at any time.

figure 11 shows the motor-supported program sequence of the functional state of the window from the basic position of the driver 23, automatically controlled from the tilted position in the direction of the closed state. The handle rotates to the horizontal position. The locking pin 13 is located in the locking pin receiving element 26, the driver moves, for example, by 18 mm to the left and, in the example, takes the driver pin 14 from the basic position to the left in the direction of the open rotary position, which is then passed through.

figure 12 shows the functional status of the window in the motor-driven closed and locked position. The locking bar 12 has reached the closed state, the locking pin 13 strikes the locking pin receiving element 26 on the left. The motor 21 runs and the driver 23 reaches the maximum stroke of eg -36 mm to the left from the basic position to the left and takes the driver pin 14 with it, since the driver is at the right stop or the right drive surface 23b. The handle rotates down to the vertical position. The window is closed and cannot yet be operated manually.

figure 13 shows the motor-assisted functional state of the window in the closed and locked position after the driver 23 has automatically returned to its basic position. The window is closed and locked. The handle is now pointing vertically down. The locking pin 13 is in the locking pin receiving element 26 in the closed position. The driving pin 14 is during the reversing. The locking bar 12 does not shift in this scenario. The handle does not move. The window remains in the closed position. The program cycle ends when the home position is returned. When the home position is reached, manual actuation of the Window using the handle possible at any time and the operator can bring the handle of the window in any desired position and bring the window manually in all possible functional positions. (p. figure 6 ) The figures described above show the mode of action of the driver and driver pin using a driver and driver pin according to the invention.

the figure 14 visualizes different arrangements of drivers and driving pins. The first alternative above shows a driver 23 that is not according to the invention and surrounds the driver pin 14 essentially without freewheeling, so that a movement of the driver 23 also directly leads to a movement of the driver pin 14 . The driver 23 can be moved according to the arrows in the direction of displacement of the locking bar by the drive and thus takes the driver pin 14 with it, which, however, because of the recess 23c open perpendicular to the arrows, also in this vertical direction, e.g. when opening the casement from the driver 23 can emerge. The drive surfaces here are the wall areas of the recess, which is U-shaped in cross section, which are spaced apart in the direction of displacement and point towards one another.

In the central second alternative according to the invention, a driver 23 is shown with a slot-shaped recess which surrounds the single driver pin 14 . Here, too, the driver 23 can be moved according to the arrows in the direction of displacement of the locking bar. Since the length of the elongated hole is greater than the extent of the driver pin 14 in this direction, the recess results in a freewheeling area during the movement of the driver until it contacts the driver pin 14 and takes it with it. Through the opening 23c, the driver pin can also step out of the recess and step back in, for example when opening the casement. Here, too, the drive surfaces are the wall regions of the recess, which are spaced apart in the direction of displacement and point towards one another.

In the third alternative shown below, which does not belong to the invention, a driver 23 interacts with two driver pins 14a and 14b spaced apart in the direction of displacement. The direction of displacement is again indicated by the arrows and corresponds to the direction of displacement of the locking bar. The drive surfaces of the driver 23 are each assigned to one of the two driver pins 14a, 14b, so that only one of the driver pins 14, 14b comes into engagement with the driver 23 during a movement. The drive surfaces are formed by the surface areas of the driver, which are spaced apart in the direction of displacement, face away from one another and point towards one of the two driver pins. Here, too, a respective drive surface is a partial area of a recess in which a respective driver pin rests during an engagement. As in the second alternative, the distance between the driver pins 14a, 14b, which is greater than the distance between the drive surfaces of the driver, also defines freewheeling, i.e. a path in which the driver 23 is not engaged with both driver pins 14a, 14b .

If the driver, as shown in the lower part of the third alternative, is arranged between the driver pins 14a and 14b, the casement can be opened.

After one of the two driver pins has been moved in order to bring the locking pin into one of the functional positions, it can be provided that the driver is moved back into a basic position in which the driver is then in engagement with the other of the two driver pins, or at least in the latter Direction is moved and has disengaged from the previously moved driver pin.
