EP2642050B1 - Locking assembly of a window or a door for a building - Google Patents

Description

The invention relates to an assembly of a window or a door for a building according to the preamble of claim 1 and a method for operating a window or a door for a building.

Such an assembly has a closure element for closing a building opening and a locking device. The closure member is adjustable between open and closed positions, and in a locked position, the locking means locks the closure member in the closed position so that the closure member can not be opened, and allows the closure member to be adjusted in an unlocked position.

Such a closure element may be, for example, a window or door wing of a building. In this case, the locking device serves to lock the window wing or the door leaf in the closed position of the window or the door. In order to allow opening of the window or the door, the locking device can be unlocked, so that in the unlocked position of the locking device, the window sash or the door leaf can be opened.

In conventional windows or doors to buildings a particular manually operable actuator is provided with which a locking device can be adjusted. Depending on the operation of the actuating element in this case the locking device can be adjusted between its locked position and its unlocked position, for example, to unlock a window sash and open or to lock in a closed position.

The actuator may be, for example, a handle, a button, a remote control or the like.

From the DE 102 37 492 B3 For example, a device for opening or closing a wing relative to a frame is known in which a drive element generates a drive movement and drives an output element for adjusting the wing via it. In this way, a drive for adjusting the wing is created, which allows opening or closing of the wing in a motor-driven manner.

Other drive devices for pivoting window or door wings in a motor-driven manner, for example, from DE 103 57 296 A1 or the DE 297 22 416 U1 known. With such electromotive drive devices, a window or door can be driven by a motor and adjusted. Such drive devices thus replace manual adjustment and allow automatic opening and closing of a window or door.

In the case of windows or doors on buildings there is a need, especially for manually adjustable window or door wings, to be able to actuate a locking device by manual actuation of an actuating element in a simple and reliable manner. This is even more true for large and heavy-weight window or door wings, in which a locking device may be difficult to move. In particular, in the case of a window which, in addition to complete opening around a vertical pivot axis, also permits tilting about a horizontal pivot axis, a locking device may have a plurality of pins or other engagement elements to be moved mechanically, which must be displaced for adjusting the locking device.

The DE 10 2009 027 760 A1 describes a drive rod fitting for a wing pivotable against a frame. The espagnolette fitting has a drive device with an assembly arranged in a folding air between the vane and the frame and with a pressure medium source arranged at an angle away from the vane and designed as an air compressor. About a driver can be acted on a pin of a drive rod to provide in this way a power assistance for the espagnolette fitting.

The DE 10 2004 015 147 A1 describes a drive device with a spindle drive for adjusting a driver. About the driver can be acted on a bolt of a drive rod to provide in this way a power assistance for a drive rod fitting available.

The EP 1 865 130 A1 describes a release arrangement for windows or doors, in which by means of a spindle drive a window sash can be unlocked.

Object of the present invention is an assembly of a window or a door for a building and a method for operating a window or a door for To provide a building that allow a smooth and haptic pleasant operation of an actuator for adjusting a locking device.

This object is achieved by an article having the features of claim 1.

Thus, in an assembly of a window or a door for a building, an auxiliary drive is provided for assisting an adjustment of the locking means in response to an operation of the operating member.

The present invention is based on the idea to provide a motorized auxiliary drive for actuating the locking device, which supports the actuation of the actuating element and thus an adjustment of the locking device, so that the actuating element can be actuated with little force in a smooth manner and one upon actuation of the Actuator adjusting the locking device between its locked position and its unlocked position takes place in a reliable and haptic pleasant way.

The auxiliary drive is used in the manner of a servo motor for assisting an actuation of the actuating element. The actuating element may in this case be designed for manual actuation, in which case the auxiliary drive engages supportively in the case of manual engagement and movement of the actuating element and generates an adjusting force for adjusting the locking device, so that a user at least does not have the full force for actuating and adjusting the locking device must spend. Likewise, however, the actuating element can also be designed for motorized operation in the context of an automatically operated window or an automatically operated door, in which both an adjustment of a locking device and an opening and closing of the closure element (a window or door leaf) takes place in a motor-driven manner ,

The auxiliary drive can in particular have a spindle drive with a spindle and a spindle nut arranged on the spindle and adjustable relative to the spindle.

Different designs of such spindle drives are conceivable and usable here.

In a first embodiment, the spindle drive, for example, have a rotatable spindle which is driven by an electric motor and having an external thread on which a spindle nut is arranged such that due to a rotational movement of the spindle, the spindle nut rolls on the spindle and is adjusted along the spindle , The spindle nut is in this case coupled to the locking device and adjusts the locking device as a result of an introduced via the rotational movement of the spindle adjusting.

In a second possible embodiment, the spindle may be fixed, while the spindle nut is rotatably mounted on the spindle and coupled to an electric motor for driving. In operation, the electric motor offset the spindle nut in a rotational movement relative to the fixed spindle, so that the spindle nut rolls on the spindle and is thereby adjusted along the spindle.

The closure element is configured by a window sash or by a door leaf of a window or a door of a building. The actuating element can in this case preferably be arranged on the closure element, while the auxiliary drive is mounted on a frame of the window or the door on which the closure element is pivotably mounted. For actuation, a user acts on the actuating element and adjusts it on the closure element, so that the locking device is adjusted over it in a manner supported by the auxiliary drive.

Preferably, the auxiliary drive, in particular the spindle drive of the auxiliary drive, arranged in a cavity of the frame formed as a hollow profile such that the auxiliary drive is at least partially bordered by the frame. In particular, those parts of the auxiliary drive, which are associated with the spindle drive can be arranged in this way within the frame, so that they are completely covered by the frame and not visible from the outside. Only a spindle nut or a carriage connected to the spindle nut protrude in this case from the frame and are slidably guided on the frame. Such an arrangement of the auxiliary drive is advantageous, for example, when the frame is used as an extrusion part, e.g. made of aluminum.

The locking device may be formed, for example, by one or more pins which are arranged displaceably on the closure element and which are operatively connected to the actuating element. In the locked position of Locking means engage the pins lockingly into associated recesses on the frame, while in the unlocked position the pins are movable out of the recesses. By actuating the actuating element, the pins between the locked position and the unlocked position can be adjusted, the auxiliary drive for supporting the adjustment, for example, can act directly on one of the pins to move it in a motor-assisted manner relative to the recess and the pins so to bring from its locking engagement with the associated recess or in locking engagement with the recesses.

For this purpose, the auxiliary drive can drive a closing piece, which is coupled, for example, with the spindle nut and slidably mounted on a housing element of the frame. The striker is in operative connection to assist the adjustment with the pin and acts for the motor assisted adjustment to the pin, so that exerted on the pin over the closing piece generated by the auxiliary drive adjusting force and this is thus adjusted in a motor-assisted manner.

The striker may be configured such that to assist in adjusting the peg in a first adjustment direction from the latched position, the striker acts on the peg with a first portion, thereby locking the peg independently of the striker in the adjustment direction of the latch Stand out not prevented. The background here is that in particular in a manually operable actuator in a so-called panic situation in which a user wants to open a window or a door quickly, the pin forming the locking device should also be adjustable independently of the closing piece and thus without motor support , In the locked position, the locking piece is thus located with a first portion on the pin on such that the closing piece can move the pin out of its locked position in a motor-driven manner, while a movement of the pin from the locked position out, by manual operation the actuating element is independent of the closing piece, not prevented. The pin can thus be manually moved out of its locked position without this opposes the auxiliary drive.

In addition, the auxiliary drive can not be designed to be self-locking, so that even when force is applied to the closing piece due to external application of force on the pin at a manual adjustment of the auxiliary drive allows adjustment of the pin.

In particular, in a panic situation so that a purely manual operation of the locking device is possible to unlock the shutter and open it.

To assist in adjusting the pin in a second adjustment direction opposite to the first adjustment direction in the direction of the locked position, the closing piece preferably acts on the pin with a second section that is different from the first section. In a reverse adjustment of the pin in the direction of the locked position (ie from an unlocked position), the striker thus acts with a different than the first section on the pin and leads it back to its locked position.

The first portion and the second portion of the striker are spaced apart along the direction of adjustment along which the striker is moved out of the latched position for adjustment of the peg, to such an extent that the peg is in a panic situation in the direction of adjustment of the second portion can not approach the transfer of the pin to an unlocked position, so that the locking device can be unlocked and the closure element can be opened.

Because the first portion and the second portion are spaced apart along the direction of adjustment, the auxiliary drive has an idle stroke, which may also be referred to as Umschaltspiel. If, after an adjustment of the pin in a motor-assisted manner, the pin is moved back into the locked position from the locked position, then the closing piece must be displaced so far in the second adjusting direction opposite to the first adjusting direction until the second section of the closing piece comes into contact with the pin. Only then can the pin be guided in a motor-assisted manner back into the locked position. Conversely, the locking piece must be moved after reaching the locked position in the adjustment, so that with a renewed adjustment of the pin from the locked position, the first portion of the closing piece in contact with the pin and can assist the adjustment of the pin motor.

Thus, upon actuation of the actuating element for adjusting the locking device from the locked position or out of the unlocked Position back into the locked position of the pin can be adjusted directly in a motor-assisted manner, it is preferably provided that the closing piece is adjusted upon reaching the locked position in the first adjustment until the first section comes into contact with the pin. Conversely, when the unlocked position is reached, the closing piece is adjusted in the second adjusting direction until the second portion comes into contact with the pin. In a forward-looking manner, the closing piece is thus adjusted upon reaching the locked position until the first portion of the closing piece comes into contact with the pin, and thus a subsequent adjustment movement of the pin from the locked position directly by the action of the first portion of the closing piece on the Cones can be supported. In an analogous manner, when the unlocked position is reached, the closing piece is moved in the second adjusting direction opposite to the first adjusting direction, until the second section comes into contact with the pin, so that the adjustment movement then takes place during a subsequent adjustment of the pin from the unlocked position the auxiliary drive can be supported by the action of the second portion of the closing piece on the pin.

In particular, when the closure element is designed as a window sash of a window, different unlocked positions can be provided. For example, in a first unlocked position, the closure element can be pivotable about a first, for example, vertically directed pivot axis for a complete opening of the closure element. In contrast, in a second unlocked position, the closure element can be pivotable about a second pivot axis which is different from the first pivot axis and which is directed horizontally, for example, so that the closure element can be tilted and thus brought into a tilted position, as is usual in building windows.

The first unlocked position may in this case correspond to an intermediate position of the locking device, which is located between the locked position and the second unlocked position. A switch in which the closing piece is moved to bring the other portion with the pin in abutment, this can be done in this case when reaching the locked position and each of the unlocked positions in an automatic manner. Preferably, however, such switching takes place only upon reaching the locked position and the second unlocked position, the end positions (and no intermediate position) correspond to the locking device.

In an advantageous development, the auxiliary drive can also be designed to support the pivoting about the - when the window or the door is mounted as intended - horizontally directed second pivot axis for tilting the closure element. For this purpose, the auxiliary drive can act, for example, on a lever mechanism in order to effect a pivoting of the closure element about the second pivot axis when the locking device is moved from the first unlocked position to the second unlocked position. The second unlocked position corresponds to a position in which the closure element can be tilted about the horizontally directed pivot axis in order to bring the closure element, for example, a window sash or a patio door in a tilted position. Since windows or doors can be heavy, the auxiliary drive simultaneously acts on the closure element when transferring the locking device to the second unlocked position in order to support tilting of the closure element about the second pivot axis when transferring to the second unlocked position and thus tilting the closure element for a user to facilitate as far as possible.

In this case, the auxiliary drive can be designed to permit tilting of the closure element out of a closed position when transferring the locking device into the second unlocked position. Likewise, in the opposite direction, the auxiliary drive in a transfer of the locking device from the second unlocked position in the direction of the first unlocked position, a tilting of the closure element in the direction of its closed position, so a Hinankippen to the frame, motor assist, so that the closing movement of the closure element can be done in a smooth, motor-assisted manner.

By means of the auxiliary drive is carried out an adjusting movement of the locking device in a motor-assisted manner upon actuation of the actuating element. In order to control the auxiliary drive in dependence on the actuation of the actuating element, a signal generator is provided which generates a signal for driving the auxiliary drive in dependence on the position of the locking device. The position of the locking device is in this case rigidly coupled to the actuating element, so that on the basis of the position of the locking device, the position of the actuating element is detected and thus takes place upon actuation of the actuating element via the signal transmitter, a control of the auxiliary drive for motor-assisted adjustment of the locking device.

The signal transmitter has a slider slidably mounted on the frame, which is adjusted in an adjustment of the locking device together with this. For example, the slider may have a recess into which engages a pin of the locking device, said pin is coupled via a shear-stiff transmission means with the actuating element, so that upon actuation of the actuating element, the transmission means and above the pin and moreover coupled to the pin Slider to be moved.

To detect the position of the locking device by measurement and to generate a signal that can be used to control the auxiliary drive, the signal generator may have at least one micro-switch, for example, with a tongue rests against an associated slide of the slider and a signal in response to the Position of the slider generated. The slide of the slider can in this case a recessed portion and one with respect to the recessed portion have raised portion which is such that when a run on the raised portion actuates a button of the microswitch and generates a corresponding signal. This signal can be supplied to a control unit, which evaluates the signal and, in response to the signal, drives the auxiliary drive to assist in the movement of the adjusting device.

In an advantageous embodiment, the signal transmitter has two microswitches, each of which is e.g. abut with a tongue at a different, associated slideway of the slider. By means of the two microswitch thus two signals are generated, which are evaluated for driving the auxiliary drive, wherein detected by evaluating the signals of both microswitches, for example, the adjustment of the slider and thus the locking device and the auxiliary drive can be controlled depending on the direction.

Basically, the adjustment of the closure element can be carried out by an electric motor, for which purpose an additional drive for an electromotive adjustment of the closure element, for example for tilting a window sash, can be provided. Not only the operation of the locking device is carried out in a motor-assisted manner, but also the adjustment of the closure element itself, wherein e.g. may be provided in a window, not make any adjustment in a motor-assisted manner, but for example only tilting about a horizontal pivot axis in a tilted position, but not pivoting to fully open about a vertical pivot axis. The adjustment can basically in motor assisted manner (ie supporting a manual movement) or completely motorized (without manual intervention).

The object is also achieved by a method for operating a window or a door for a building. In the method, which can be carried out in particular by means of an assembly of the aforementioned type, an auxiliary drive is provided, which supports an adjustment of the locking device in response to an actuation of the actuating element.

Advantages and advantageous embodiments of the method are obtained in an analogous manner from the above.

In the method, it can be provided that, upon actuation of the actuating element in at least one predetermined first section, the auxiliary drive is actuated along an actuation path of the actuation element for assisting the adjustment of the locking device, but not actuated in at least one second section that differs from the at least one first section becomes.

For example, it may be provided that in a window when actuating the pivotable actuating element for unlocking the locking device in a first angular range initially no control of the auxiliary drive and correspondingly also no motor support the adjustment takes place. Only on further actuation of the actuating element of the auxiliary drive is driven and then supports the adjustment of the locking device, wherein on the further actuation adjustment of the locking device under the action of the auxiliary drive can at least largely be done automatically until a first unlocked (intermediate) position or a second unlocked (End-) position is reached.

Accordingly, it may initially be provided, even when the actuating element is actuated out of the first or second unlocked position of the locking device, that no motor support is yet provided, but only when the actuating element is pivoted beyond a predetermined angle.

Fig. 14 shows a schematic view of a window 1, in which a closure element in the form of a window sash 13 on a frame 10 about hinges 11, 12 is pivotally arranged such that the sash 13 can be pivoted about a first pivot axis L1. The window sash 13 can in this case be brought into a closed position in which it rests against the window frame 10, wherein it is in this closed position via a (in Fig. 14 not shown) locking device can be locked so that an opening of the sash 13 without actuation of an actuating element 3 in the form of a manually operated handle on the sash 13 is not possible.

In a locked position of the window sash 13 is thus locked to the window frame 10. By actuating the actuating element 3, the window sash 13 can be unlocked so that it can be opened, wherein the locking device in a conventional manner has different positions in which the sash 13 is unlocked relative to the frame 10 and can be pivoted in different ways.

Thus, the window sash 13 can be pivoted in a first unlocked position about the hinges 11, 12 and thus about the vertically directed first pivot axis L1. In a second unlocked position, however, the window sash 13 can be tilted about a second pivot axis L2, which is directed horizontally in contrast to the vertical first pivot axis L1, so that the sash 13 can be transferred in a tilted position relative to the frame 10.

For the purposes of the present invention, in the window 1, the adjusting of the locking device in a motor-assisted manner is to take place via an auxiliary drive, as described below with reference to a different view in FIG Fig. 1 to 13 illustrated embodiment to be explained.

Fig. 1 shows a view of an embodiment of a frame 10 of a window having a handle side 100 and a handle side 100 opposite hinge side 101 on which the hinges 11, 12 are arranged, and is completed by a bottom 102 and a top 103.

On the handle side 100 next to a magnetic catch 109 an auxiliary drive 2 is arranged, which in an enlarged view of the frame 10 in Fig. 2 and in separate views in Fig. 3A, 3B . 4A . 4B and 5 is shown. The magnetic catch 109 serves to hold the sash 13 in its closed position when the locking device is not (yet) locked.

The auxiliary drive 2 is designed in the manner of a spindle drive and serves to assist a motor via the actuating element 3 adjusting a locking device which locks the window sash 13 relative to the frame 10 in the closed position. The locking device has a pin 300 (see Fig. 5 ), which is coupled via a shear-stiff transmission means 30 with the actuating element 3 such that during a pivoting movement of the actuating element 3 about a pivot axis S, the transmission means 30 moves and the pin 300 is adjusted (the locking device additionally comprises further pins 301, of which one cooperates with a signal generator 5, such as in Fig. 7 is shown and will be explained below).

The pin 300 of the locking device engages in a locked position in which the sash is locked to the frame 10 in a recess 212 of a housing member 21 of the auxiliary drive 2 such that the pin 300 prevents movement of the sash 13 relative to the frame 10 , Relative to this recess 212, the pin 300 is adjusted upon actuation of the actuating element 3, so that it passes out of a locking engagement, the locking device is thus unlocked and the sash 13 can be pivoted or tilted to the frame 10.

It should be noted that around the frame 10 distributed around several pins 300-303 (eg six to eight pins) are provided, which together in the locked position, the frame 10 with the window sash 13 lock together and actuated via the transmission means 30 for unlocking can be (see also Fig. 19 , which will be discussed below).

By means of in Fig. 3A, 3B and 4A . 4B shown auxiliary drive 2, this adjustment of the pin 300-303 can be supported by a motor. For this purpose, the auxiliary drive 2 has a spindle drive 20 with a spindle 201 and a spindle nut 200. The spindle 201 is rotatably supported about a longitudinal axis L and coupled to an electric motor (not shown) for driving the spindle 201. The spindle 201 has an external thread, which engages with a threaded bore 204 of the spindle nut 200 in such a way that upon rotation of the spindle 201 about the longitudinal axis L, the spindle nut 200 rolls on the spindle 201 and along the longitudinal axis L relative to the spindle 201 is adjusted.

The spindle nut 200 is non-rotatably arranged in a housing 202 of the spindle drive 20 and passes through a recess of the housing 202 with a connecting piece 205, via which a closing piece 211 via screws 206 fixedly connected to the spindle nut 200 (see Fig. 4A ). During a rotational movement of the spindle 201 about the longitudinal axis L, the spindle nut 200 and thus also the closing piece 211 are thus moved along the longitudinal axis L, so that the closing piece 211 slides longitudinally along a guide track 210 on the housing element 21.

The spindle drive 20 is connected via attachment portions 105, 106 with a mounting plate 104, to which also the housing member 21 is attached, and connected to the frame 10 above. How out Fig. 4A can be seen, the spindle drive 20 via a mounting cover 107 and screws 108 on the one hand to the mounting portion 106 and a housing cover 203 on the other hand connected to the mounting portion 105.

On the mounting plate 104 and two micro-switches 6, 7 are arranged, which serve to detect a pivotal position of the sash 13 relative to the frame 10 and generate a signal depending on the position of the sash 13 relative to the frame 10. The microswitch 6 is arranged on the mounting plate 104 via a housing 60 and held thereon.

Basically, only one of the microswitches 6, 7 must be used, so that the presentation shows advantageous alternatives. When the window sash 13 is opened, the auxiliary drive 2 is switched off for safety reasons. Only when the respectively used microswitch 6, 7 is actuated in the closed position of the window sash 13, the auxiliary drive 2 is ready for operation and can be controlled.

The spindle drive 20 is connected to a supply line 22 via which the electric motor of the spindle drive 20 is electrically supplied and controlled.

As can be seen from the cross-sectional view transversely to the frame 10 with the window sash 13 arranged thereon, the journal 300 is rigidly connected to the transmission means 30 and coupled to the actuating element 3 via it. The pin 300 engages in the recess 212 of the housing member 21 and projects into the displacement of the closing piece 211 on the housing element 21, so that act on the pin 300 via the closing piece 211 of the spindle drive 20 and about the adjustment of the pin 300 and thus the Entire locking device can support motor.

The auxiliary drive 2 is used for motor assisting the adjustment of the locking device in response to an actuation of the actuating element 3. The control of the auxiliary drive 2 takes place via the signal generator 5, as will be described in detail below. Depending on the operation and the assumed positions of the actuating element 3, the result in FIGS. 6A to 6F shown different positions of the closing piece 211 and the pin 300, on which the closing piece 211 and above the auxiliary drive 2 act.

In a starting position, in which the actuating element 3, the in Fig. 6A In the left-hand position shown above with the handle facing downwards, the pin 300 is located in an upper, locking portion 212A of the recess 212 and locks the sash 13 relative to the frame 10. In particular, the sash 13 can not be in this position of the pin 300 the recess 212 are pivoted out, so that the window sash 13 can not be pivoted about its first pivot axis L1 nor about its second pivot axis L2.

Will now, as in Fig. 6A shown lower left, the actuator 3 is pivoted in a pivoting V, the pin 300 is under the action of Actuation of the actuating element 3 moves in an adjustment direction X, this being done initially without motor support.

If the actuating element 3 has been pivoted through an angle α (eg 15 °), the auxiliary drive 2 is actuated and displaces the journal 300 in the adjustment direction X by motor and without stopping by the angle α '(see Fig. 6B left top) into a position in which the actuator 3 is directed horizontally and the pin 300 is in a first unlocked position in which the sash 13 pivots about the first pivot axis L1 and the window can thus be fully opened. In particular, in this position, as in Fig. 6B 9, the pin 300 is moved out of the recess 212 in an opening direction Y, because it is in the area of a portion 212B of the recess 212, which is not limited in the opening direction Y.

To adjust the pin 300 from the in Fig. 6A position shown in the in Fig. 6B shown position, the closing piece 211 acts with a first portion 213 on the pin 300 and adjusts this motor in the adjustment X.

Is based on the in Fig. 6B shown position pivoted further in the pivoting direction V, so initially in an angular range β (eg 15 °) of the auxiliary drive 2 is not activated, so that initially no motor support the adjustment movement of the pin 300 takes place. Only when the actuating element 3 is pivoted beyond the angle β in the pivoting direction V, the auxiliary drive 2 is driven and moved, as in Fig. 6C shown, the pin 300 automatically and without interruption in the in Fig. 6C illustrated, second unlocked position in which the sash 13 can be tilted about the second pivot axis L2. In this position, the actuating element 3 is vertically upwards. For transferring into this position, the auxiliary drive 2 acts on the pin 300 via the first section 213 of the closing piece 211 and displaces the pin 300 by an adjustment path which corresponds to an angle β 'on the actuation path of the actuating element 3.

For adjusting the pin 300 from its locked position according to Fig. 6A in its (second) unlocked position according to Fig. 6C the auxiliary drive 2 acts on the pin 300 via the first section 213 of the closing piece 211. In order to adjust the pin 300 in a direction of the first adjustment X opposite, second adjustment X 'back towards the locked position, a second portion 214 of the Closing piece 211 of the first portion 213 opposite side of the pin 300 are approximated, which requires that the locking piece 211 is moved in the opposite, second adjustment direction X 'until the second portion 214 of the closing piece 211 comes into contact with the pin 300. This is done automatically when reaching the second unlocked position according to Fig. 6C , so that in a subsequent actuation of the actuating element 3 in an opposite pivoting direction V ', as in Fig. 6D shown lower left, the auxiliary drive 2 is immediately ready for use and can support a return movement of the pin 300 by motor.

As in Fig. 6D shown, in an actuation of the actuating element 3 in the pivoting direction V 'from the second unlocked position out first again in an angular range γ (eg 15 °) no motor support the adjustment of the pin 300. Only when the angle γ on actuation of the actuating element 3 is exceeded, the auxiliary drive 2 is activated and transfers the pin 300 in the first unlocked position, shown in FIG Fig. 6E in which the actuating element 3 is pivoted by the angle γ 'and directed horizontally.

Upon further actuation of the actuating element 3 in the pivoting direction V 'from the first unlocked position out again initially in an angular range δ (eg 15 °) no activation of the auxiliary drive 2. This is driven only when the angle δ is exceeded and then transferred in motor assisted manner, the pin 300 in its locked position according to Fig. 6F to which the pin 300 is transferred by an adjustment angle corresponding to an angle δ 'of the actuating element 3 in the illustrated end position.

Is that in Fig. 6F reached locked position shown, the locking piece 211 is automatically moved back in the adjustment X back until the first section 213 again comes into contact with the pin 300 so that upon re-actuation of the actuating element 3 from one of the locked position of the locking device corresponding position out the auxiliary drive 2 is immediately ready for use. The auxiliary drive 2 is thus automatically when reaching the locked position according to Fig. 6F in the in Fig. 6A shown position returned.

By using the auxiliary drive 2, an actuation of the actuating element 3 and an adjustment of the locking device with the pins 300-303 thus in motor supported manner, so that actuation of the actuating element 3 can be carried out under application of low forces in a simple, haptic pleasant way.

How out Fig. 6A it can be seen, in the locked position of the pin 300 in a so-called panic situation with sudden, rapid actuation of the actuating element 3, the pin 300 can in principle be moved independently of the closing piece 211 from the locked position. This is possible because the second portion 214 of the striker 211 does not prevent movement of the trunnion 300 relative to the striker 211 in the adjustment direction X from the locked position and thus the trunnion 300 is disengaged from the portion solely due to manual actuation of the actuator 3 212A of the recess 212 of the housing member 21 can be brought so that the sash 30 can be opened in such a panic situation.

In addition, the spindle drive 20 is not self-locking, so that the spindle drive 20 does not prevent manual adjustment of the pin 300. With external force on the spindle nut 200 via the pin 300, the spindle nut 200 and the spindle 201 are basically mutually adjustable, so that a manual movement of the pin 300 is not prevented by the spindle drive 20.

For this purpose, an idle stroke is provided, which is predetermined by the spaced arrangement of the sections 213, 214 of the closing piece 211 along the adjustment direction X. This idle stroke allows one hand, an independent adjustment of the pin 300 in a panic situation. On the other hand, this Leerhub a Umschaltspiel result, in the manner described in reaching the second unlocked position (see Fig. 6C ) and the locked position (see Fig. 6F ) must be compensated by back process of the closing piece 211.

In the illustrated embodiment, the portion 214 is rectilinear shaped (see, eg Fig. 6A ). It is also conceivable, however, to form the section 214 curved in the manner of a hook by the section 214 is concavely curved at its edge facing the pin 300. This causes the pin 300 to move in the direction X '(see Fig. 6E ) can not get out of abutment with section 214. In addition, in this way, a force component on the pin 300 in the direction of a tightening (contrary to the direction Y according to FIG Fig. 6B ) on the pin 300 be exercised when, by action of the portion 214 of the pin 300 is moved to lock (see FIGS. 6D to 6F ).

As described, the control of the auxiliary drive 2 in response to the actuation of the actuating element 3. The control is carried out by the position of the rigidly coupled to the actuator 3 transmission means 30 is detected by the signal generator 5, in response to the position of the transmission means 30 to generate a signal that - as in Fig. 2 illustrated - an electronic control unit 8 is supplied, which in turn evaluates the signals supplied to it and controls the auxiliary drive 2 accordingly. The control unit 8 is for this purpose, as in Fig. 2 represented, via lines 80, 81, 82, 83 connected to the signal generator 5, the microswitches 6, 7 and the auxiliary drive 2.

The signal generator 5, which in one embodiment in Fig. 7 to 12 is shown, has a slider 51 which is coupled via a recess 510 with the pin 301 and above with the transmission means 30 such that upon movement of the transmission means 30 and concomitantly with the pin 301, the slider 51 is moved.

The slider 51 of the signal generator 5 is slidably guided on a housing member 50 along a guide track 500. The pin 301 engages through a recess 502 of the housing member 50 into the recess 510 of the slider 51 a.

As the exploded view according to Fig. 10 can be seen, the signal generator 5 has two microswitches 52, 53 which cooperate via a respective tongue 520, 530 with slides 511, 512 of the slider 51, depending on the position of the slider 51 relative to the microswitches 52, 53 a signal and transmit to the control electronics 8 for evaluation (the tabs 520, 530 are not necessarily provided, the microswitches 52, 53 could also be directly against the slides 511, 512). The microswitches 52, 53 are arranged in a receiving chamber 501 on the housing member 50 and held on the housing member 50 above.

The tongues 520, 530 are each associated with a slide track 511, 512 and slide on an adjustment of the slider 52 along the respectively associated slide track 511, 512. The slide tracks 511, 512 are thereby, as in Fig. 12 shown, different and each have a recessed portion 511 B, 512 A and a raised Section 511A, 512B, along which the associated tongue 520, 530 slides during the adjustment of the slider 51. If the tongue 520, 530 runs on the associated raised portion 511A, 512B, then the tongue 520, 530 is displaced and a pushbutton 521, 531 of the microswitch 52, 53 is actuated, as a result of which a signal is generated and sent to the control electronics 8 ,

In the locked position of the locking device, the pin 301 is initially in a portion 502A of the recess 502 of the housing member 50 and thus locks the sash 13 with the frame 10. In this position of the pin 301, the slider 51 is in the in Fig. 11A position shown. The tongue 520 of the microswitch 52 abuts the recessed portion 211B (see FIG Fig. 12 ), while the tongue 530 is still in front of the raised portion 512B at its end facing away from the recessed portion 512A, so that both microswitches 52, 53 are not actuated.

Now, the actuating element 3, as in Fig. 11B is shown, pivoted in the adjustment direction V, the slider 51 is moved via the pin 301, so that the tongue 520 slides along the recessed portion 511 B of the slide 511, without thereby the microswitch 52 is actuated. The tongue 530, however, runs on the raised portion 512B of the slide 512, wherein an actuation of the microswitch 53 takes place only when the tongue 530, the in Fig. 11B has reached the position shown and accumulated on the raised portion 512B. This position corresponds to an angle α, by which the actuating element 3 has been pivoted, so that when the angle α is exceeded, a signal is generated at the microswitch 53 and directed to the electronic control unit 8 corresponding to the auxiliary drive 2 for motor assisting the adjusting movement of the locking device controls.

The control of the auxiliary drive 2 takes place until the slider 51, the in Fig. 11C has reached shown position in which the actuating element 3 has been pivoted by a further angle α 'and the horizontal position according to Fig. 11C occupies. In this position, the tongue 530 is still on the raised portion 512B of the slide 512, and the tongue 520 has now accumulated on the raised portion 511A of the associated slide 511 so that the microswitch 52 has also been actuated, and thus both microswitches 52, 53 generate a signal. If the control electronics 8 receives a signal from both microswitches 52, 53, then the auxiliary drive 2 is switched off, so that (initially) no further control of the auxiliary drive 2 takes place.

Will, as in Fig. 11D 3, the actuator 3 manually pivots in the pivoting direction V while exceeding the angle β (eg, 15 °), the tongue 520 of the microswitch 52 slides on the raised portion 511A, while the tongue 530 slides down from the raised portion 512B to the recessed portion 512A slides. Thus, only the microswitch 52 is actuated, but not the microswitch 53, so that the control electronics 8 receives only one signal from the microswitch 52 and correspondingly drives the auxiliary drive 2 for motor assisting the further adjustment movement of the locking device.

The auxiliary drive 2 now moves in a motor-assisted manner, the pin 300-303 by the angle β ', as in Fig. 11E shown in the second unlocked position. Upon reaching the second unlocked position of the auxiliary drive 2 is stopped, wherein - as described above - the closing piece 211 can be moved back until the second portion 214 comes into contact with the pin 300.

When the actuating element 3 is retracted, as in FIG Fig. 11F shown, in turn, initially no activation of the auxiliary drive 2, until the actuating element 3 has been pivoted by an angle greater than the angle γ in the reverse pivoting direction V '. The angle γ corresponds to the position of the slider 51, in which the tongue 520 in turn accumulated on the raised portion 511A, so that the microswitch 52 is actuated and a signal corresponding to a signal to the control electronics 8 is discharged.

The adjustment now runs the other way around, finally, the slider 51 turn the in Fig. 11H shown position in which the pins 300-303 are in their locked position in the associated recesses 212, 502. In the end position according to Fig. 11H both microswitches 52, 53 are not actuated.

Figs. 13A and 13B show in schematic diagrams the control of the auxiliary drive 2 in response to an actuation movement of the actuating element. 3 Fig. 13A shows here first the operation of the actuating element 3 from a locked position on the first unlocked position to the second unlocked position (tilted position). Fig. 13B Figure 12 shows the reverse movement from the second unlocked position (tilted position) past the first unlocked position back to the locked position.

As in Fig. 13A shown, the auxiliary drive 2 is initially not driven at a pivoting of the actuating element 3 by an angle α from the locked position out. If the actuating element 3 is pivoted beyond the angle α, then the auxiliary drive 2 is controlled such that it supports the further actuating movement over the angle α 'away, until the actuating element 3 reaches the horizontal position corresponding to the first unlocked position of the locking device. Here, the auxiliary drive 2 is stopped, and upon further pivoting movement of the actuating element 3, no motor support initially takes place by activation of the auxiliary drive 2 until the actuating element 3 is pivoted beyond the angle β. When the angle β is exceeded, the auxiliary drive 2 is again activated and supports the further actuating movement over the angle β 'until the actuating element 3 reaches the vertical position corresponding to the second unlocked position of the locking device.

Conversely, the actuator 3 is moved out of the second unlocked position, as in Fig. 13B is shown, initially takes place at a pivoting movement about the angle γ no motor support. Upon further pivoting of the actuating element 3, the auxiliary drive 2 is then actuated until it reaches the horizontal position and supports the actuating movement over the angle γ '. Upon reaching the horizontal position of the auxiliary drive 2 is initially stopped again. Upon further pivoting of the actuating element 3 by the angle δ initially no motor support. Only when the angle δ is exceeded, the auxiliary drive 2 is driven again and supports the further transfer of the actuating element 3 by the angle δ 'in the locked position corresponding, vertical position in which the actuating element 3 points downward.

15 to 17 show a further embodiment of a window 1, which is substantially functionally identical to the above-described embodiment and further developed only in that on the lower frame portion 102 of the frame 10, an engagement device 9 with a bolt engagement 92 for additional support of the sash 13 to the frame 10 is provided in a closed position of the window sash 13.

The engagement device 9 has two engagement jaws 90, 91, which serve to a arranged on the transfer means 30 pin 302, the part of the Locking device is to lock or release depending on the position of the transmission means 30. In a locked position, in which the window sash 13 is in a closed position on the frame 10 and locked to the frame 10, the pin 302 engages behind the engagement jaw 91. By means of the auxiliary drive 2 motor assisted adjustment of the transmission means 30 in the Adjustment X, the pin 302 in a in Fig. 16 shown first unlocked position can be moved, in which the pin 302 can be passed between the engagement jaws 90, 91, so that the sash 13 for opening about the vertical pivot axis L1 (see Fig. 14 ) can be pivoted. In a second unlocked position, the pin 302 is engaged with the engagement jaw 90, so that the window sash 13 indeed around the horizontal pivot axis L2 (see Fig. 14 ), but can not be pivoted about the vertical pivot axis L1. By actuating the actuating element 3, the pin 302 can be moved between its different positions and thus brought into engagement and out of engagement with the engaging jaws 90, 91.

The engagement device 9 additionally has a bolt engagement 92 which is fixedly arranged on the lower frame portion 102 of the frame 10 and provides an engagement for a retaining bolt 31 fixedly arranged on the window sash 13.

The background is that with a motor force via the auxiliary drive 2 to the transfer means 30 in the adjustment direction X '(see Fig. 16 ) due to friction of the transmission means 30 with the sash 13 there is a force on the sash 13, as a result of which the sash 13 undergoes an upward force F, which tries to raise the sash 13. This can lead to a tilting of the window sash 13 with the frame 10, as a result of which an adjustment of the sash 13 about one of the pivot axes L1, L2 (depending on the locking position of the pins 300-303) can be difficult or even prevented.

To counteract in the closed position of the sash 13 a lifting of the sash 13 with a force on the transmission means 30 in the adjustment direction X ', the retaining bolt 31 is arranged on the sash 13, which in the closed position of the sash 13 in engagement with an engagement chamber 921 of Bolzeneingriffs 92 stands by a head 310 of the retaining bolt 31 rests in the engaging chamber 921 and a shaft 311 of the retaining bolt 31, a recess 920 of the bolt engagement 92 passes through such that the retaining bolt 31 with its head 310 in the Closed position of the sash 13 by abutment against the upper, the recess 920 supporting wall of the bolt engagement 92 prevents lifting of the sash 13.

The bolt engagement 92 is opened in such a way in a direction perpendicular to the plane of extension of the window frame 10, that upon pivoting of the window sash 13 about the pivot axis L1 (see Fig. 14 ) can be moved out of the bolt engagement 92 to open the window 1 of the retaining bolt 31. When tilting the sash 13 about the horizontal pivot axis L2, however, the retaining pin 31 remains in engagement with the bolt engagement 92, so defined on the bolt engagement 92 a tipping point and thus a smooth tilting of the sash 13 is made possible about the pivot axis L2.

Figs. 18 to 23A . 23B show an embodiment of a window 1 with a window frame 10 and a pivotally mounted thereon sash 13, in which between the frame 10 and the window sash 13 in the region of a top 103 of the frame 10, a lever mechanism 4 is arranged, which serves to tilt the window sash 13 relative to the frame 10 to guide the horizontally directed second pivot axis L2 mechanically and also to support the motor.

Fig. 18 shows an overall view of the window 1, which does not differ in its basic structure from the window described above. Fig. 19 shows a separate view of a locking device of the sash 13, in which pins 300-303 are coupled via a transmission means 30 with an actuating element 3 in the form of a handle. The transfer means 30 is slidably guided on a linkage 130 fixedly arranged on the sash 13 and can be moved tangentially along the linkage 130 by adjustment of the actuating element 3 in order to unlock the trunnions 300-303 between their locked position, their first unlocked position and their second one Position - analogously as described above - to adjust. Fig. 19 shows the locking device in interaction with the auxiliary drive 2, the signal generator 5 and the engagement device 9, which are each arranged on the frame 10. Fig. 20 shows the locking device in conjunction with the frame 10 and thus illustrates the spatial positional relationship between the locking device, in particular the transmission means 30, and the frame 10th

The lever mechanism 4, shown in individual views in Figs. 21 to 23A . 23B , Has a first lever 40, which is pivotally mounted with a first end 400 via a slot 402 to one and on the other to a certain Gleitweg slidably mounted on the fixed to the window sash 13 linkage 130. The lever 40 carries at its second end 401, the hinge 11 and is hinged to the frame 10 above.

With the first lever 40, a second lever 41 is pivotally coupled via an end 410. The second lever 41 is articulated about its second end 411 and slidably disposed on a slot 412 of the linkage 130 by a certain displacement.

The second lever 41 is coupled to a third lever 42, which is arranged with its one end 420 pivotally mounted on the linkage 130 and with its second end 421 articulated to the second lever 41.

The third lever 42 has a link 422, in which an adjusting pin 304 engages, which is connected to the transmission means 30 and by moving the transmission means 30 in an adjustment direction X or in an opposite adjustment direction X 'relative to the third lever 42 along the Gate 422 can be moved to pivot in this way the lever 42 relative to the linkage 130 and thereby to drive the lever mechanism 4 (the adjustment direction X and the opposite adjustment direction X 'correspond to the adjustment directions X, X' according to FIGS. 6A to 6F ).

As in Fig. 22 illustrated, the transmission means 30 is slidably guided on the linkage 130 via sliding guides 305 and can, driven by the actuating element 3 and motor-assisted via the auxiliary drive 2, be moved relative to the linkage 130.

Fig. 23A shows the lever mechanism 4 in an initial position which corresponds to the locked position of the locking device with the window sash 13 closed. In this initial position, the levers 40, 41, 42 are aligned with each other and are not pivoted to each other. The window sash 13 is largely approximated to the frame 10 in this position. The window 1 is in a closed position.

How out Fig. 23A can be seen, is in the starting position of the adjusting pin 304 in an end position 422A in the gate 422 a. Will now by pressing the Actuator 3 and supported by the auxiliary drive 2, the transfer means 30 moves in the adjustment direction X, so the adjusting pin 304 is displaced in the link 422 and enters a center position 422 B, which corresponds to the first unlocked position of the locking device in which the sash 13 the first, vertically directed pivot axis L1 (see Fig. 18 ) can be pivoted to fully open the window 1. Because the gate between the end position 422A and the center position 422B runs in a straight line along a connecting line between the articulation points at the ends 420, 421 of the lever 42, the lever 42 is not pivoted in such a displacement of the adjusting pin 304.

However, if the transmission means 30 is moved further in the adjustment direction X due to further movement of the actuating element 3 and the auxiliary drive 2, the adjusting pin 304 enters a curved section of the link 422 and enters the in Fig. 23B illustrated end position 422 C, in which by the action of the adjusting pin 304, the lever 42 has been pivoted about its first end 420 relative to the linkage 130. By pivoting the lever 42 and the lever 41 and above the lever 40 has been moved, so that the hinge 11 is removed from the linkage 130 and corresponding to the sash 13 about its second, horizontally directed pivot axis L2 (see Fig. 18 ) has been pivoted.

Because the adjustment of the adjusting pin 304 takes place in a motor-assisted manner by means of the auxiliary drive 2, by tilting the adjusting pin 304 in the link 422 via the lever mechanism 4, the tilting of the sash 13 about its second pivot axis L2 is motor-assisted, so that only a small amount of force is required for Moving the sash 13 is required.

In a reverse adjustment in the opposite direction of adjustment X ', the process is reversed. By adjusting the adjusting pin 304 from the in Fig. 23B shown end position 422C and the method in the gate 422, the lever 42 and also the levers 41 and 40 back into the in Fig. 23A shown starting position pivoted, in which the sash 13 in turn is approximated to the frame 10. The tilting back of the sash 13 in its closed position is thus supported by the motor 2 by means of the auxiliary drive.

By the lever mechanism 4, a translation of the adjusting movement of the adjusting pin 304 is effected. A comparatively small displacement of the adjusting pin 304 is converted into a comparatively large displacement stroke of the end 401 of the lever 40, via which the hinge 11 is held.

An auxiliary drive of the type described here is not limited to use in a window of a building, but can basically also be used in doors or other flaps on buildings.

In addition, a closure element, such as a window sash or a door leaf, not only be pivotally mounted. An auxiliary drive can also be used in the case of a closure element that is displaceable in a sliding manner in order to support the adjustment of a locking device by a motor.
