Description

The invention relates to an unlocking arrangement for windows, doors or the like. With a mounting device for fixed mounting of Entriegelungsanordnung to a fixed frame or a wing of a window, a door or the like., And an electric motor drive assembly with a locking fitting of the window, the door or the like. can be coupled.

In the DE 196 48 147 C1 is proposed a motor-driven Kippöffnungseinrichtung for windows, doors or the like, arranged with a window frame of the window wing drive unit, which interacts with a arranged on the casement of the window coupling element for Kippöffnungs- or Kippschließvorgang, wherein the wing drive unit and coupling element as a pair of fittings in the opposite position at a distance are arranged to the tilt axis of the sash.

From the DE 197 19 941 C2 is an electric motor driven tilting opening device for windows, doors or the like, arranged with a frame of the window, a housing having a wing drive unit, which cooperates with a arranged on the sash of the window, having a housing coupling element for the Kippöffnungsbeziehungsweise Kippschließvorgang, and with one on the sash arranged, a housing having locking fitting which drives at least one locking member which cooperates with a counter-locking member of the window frame, wherein the locking fitting comprises an electric motor drive means.

The known devices each have a drive for unlocking and tipping open a wing. A complete rotary opening of the wing is either not provided or possible only after an electric motor unlocking. Because there is a coupling between a drive and the locking fitting, it is not possible to drive the locking fitting via a manual operating element and to manually open a wing in an emergency.

From the DE 32 23 808 A1 a window is known which offers the possibility of automatic ventilation. The drive assembly used for this purpose is installed in a rotary handle, which is exclusively rotatable relative to a support plate including the drive assembly.

The FR 2 8731 49 A describes a device for moving locking bolts of a door between an open and a closed position by means of a drive arrangement or manually by means of a lever.

The DE 41 15 528 A1 describes a burglar-resistant locking front door lock with remote control. The front door in which the lock is installed can be locked in one or more places both with a key and automatically after closing the door.

Object of the present invention is to provide a simply constructed, both manually and automatically operable unlocking.

This object is achieved in a simple and surprising manner by a Entriegelungsanordnung of the aforementioned type, in which a second drive is provided, via which the electromotive drive arrangement is at least partially movable relative to the mounting device and linear parallel to the wing plane. The mounted unlocking arrangement is mechanically coupled to a locking fitting, so that a locking element of the locking fitting can be moved over the electric motor drive. If now there is a power failure or other fault, the electric motor drive can not be driven, so that via the electric motor drive and no displacement of the locking element or a cooperating drive rod is possible. Now, if the entire drive assembly or a part thereof, which is provided according to the invention, can be displaced via a second drive, so is displaced at a displacement of at least a portion of the drive assembly due to the mechanical coupling with the locking fitting and the locking element or the drive rod. Thus, it is possible, even in case of power failure or otherwise disturbance, which leads to the failure of the electric motor drive to operate the locking element and unlock a wing, so that it can be opened in rotation. After unlocking the wing can be opened in rotation. Even if there is no malfunction, the sash can be opened (without rotation) without actuating the electromotive drive. It is understood that in reverse order, the wing closed and then can be locked again via the second drive by the drive assembly or a part thereof is moved in the opposite direction relative to the mounting device. In principle, it is conceivable to decouple a part of the drive arrangement, eg a drive mechanism, before actuating the second drive for unlocking the locking fitting and to move only this part relative to the mounting device. Preferably, however, the entire drive assembly is moved by the second drive.

The unlocking arrangement according to the invention is preferably retrofittable in windows or doors.

In principle, it can be provided that at least part of the drive arrangement is displaceable relative to the mounting device with a correspondingly large expenditure of force. For example, a part or the entire drive arrangement could be arranged on a kind of slide, which is guided on the mounting device and by (manual) train or pressure is displaced. The displaceable (drivable) carriage represents the second drive in this case. From this example it follows that the term "second drive" in the sense of the invention is to be understood very broadly. As a second drive or component of a second drive, for example, a movement of at least a portion of the drive assembly relative to the mounting device triggering levers, power storage or spring elements that support, for example, manually initiated relative movement, or electric, pneumatic or hydraulic drives in question, which can cause a relative movement of at least one part, preferably the entire drive assembly relative to the mounting device.

According to an advantageous embodiment, the second drive may comprise an actuating handle. This can e.g. be attached to a previously mentioned carriage and used to move the carriage together with the drive assembly relative to the mounting device. Furthermore, the actuating handle can be used after unlocking to open the wing.

In a particularly preferred embodiment it can be provided that the second drive, in particular the actuating handle, cooperates with a translation device effecting the relative movement between the drive arrangement and the mounting device. By a translation device, for example, a rotational movement of an actuating handle can be converted into a linear movement of the drive assembly relative to the mounting device. By choosing a suitable transmission ratio can thus be reduced, the force required to move the drive assembly relative to the mounting device. For example, may be provided as a translation device, a transmission. It should be noted that the second drive, in particular the actuating handle, is not moved when the electromotive drive is actuated. He is not involved in the electromotive drive process.

A preferred development is characterized in that the translation device has an eccentric disc, which with a mandrel of the rotatably arranged actuating handle is coupled and is rotatably mounted on the mounting device. With such a translation device designed the drive assembly can be moved with little effort relative to the mounting device.

It is particularly preferred if a housing is provided in which the drive arrangement is arranged. On the one hand by the drive assembly is arranged protected. On the other hand acts such a designed Entriegelungsanordnung visually appealing. On a housing, the actuator can be arranged easily.

According to a development it can be provided that the housing is movable relative to the mounting device. This makes it possible to secure the drive assembly in the housing and to move only the housing relative to the mounting device. As a result, the drive assembly is also automatically moved relative to the mounting device.

According to a particularly preferred embodiment of the invention, the unlocking arrangement can be designed as an electromotive Kippöfnungseinrichtung for tilting open a wing. In particular, it can be provided that by unlocking the locking fitting as well as tilting a wing can be realized by driving the electric motor drive. Thus, in contrast to the prior art, no two drives, namely a Entriegelungsantrieb and a Flügelöffnungsantrieb necessary, but both functions can be realized with a single drive. It is understood that by the drive arrangement of the wing can also be closed and locked.

Advantageously, a coupling device for coupling the drive assembly and a driver, in particular a Treibstangenmitnehmers, a Verriegetungsbeschlags provided. By displacing the drive arrangement, the driver and thus, for example, a drive rod can thereby also be displaced so that a locking element arranged on the locking element, eg a locking bolt, can be displaced between different positions, for example a rotational opening pitch, a closed position and a tilting (readiness) position ,

In a preferred embodiment of the invention can be provided that the drive assembly comprises an electric motor drive and a driven thereby drive mechanism, wherein the coupling device is coupled to a drive mechanism. The drive mechanism may, for example, comprise a spindle, by means of which a nut guided thereon can be adjusted in the vertical direction. The coupling device may for example be pivotally connected to the mother. Alternatively, it is conceivable that the drive mechanism comprises a rack or a gear.

Further advantages arise when a Kippöffnungsbegrenzung is provided. The tilting opening limitation ensures that a wing reaches a defined tilt opening position and is not moved beyond this defined position. For example, a holding part of the Kippöffnungsbegrenzung be arranged on the fixed frame and connected both in a closed position and at a Kippöffnungsstellung the wing with the coupling element. When the coupling element is fastened on the wing side to the drive arrangement and on the other hand is held on the fixed frame side, the tilting opening of the wing is limited. In this case, the coupling element can be guided with a portion in the holding part. The holding part is preferably designed or arranged such that at a rotational opening position, ie in particular when the drive arrangement was adjusted relative to the mounting device, the coupling element and ds holding part disengaged.

Particularly advantageous is an embodiment in which the coupling device or the mounting device comprises a control device in which a control part of the mounting device or the coupling device is guided. By this measure, it is possible during a first adjustment of the coupling device by means of the electromotive drive to bring the locking fitting in a Kippbereitschaftsstellung, so at least partially unlock, and to realize during a second adjustment of the coupling device by means of the electric motor drive the tilting opening. Thus, only one drive is necessary to both drive the locking fitting and to realize the deployment movement of the wing. For example, the control device may be formed as a control groove, which has a first vertical portion and a second, adjoining thereto angled portion. This second section may be part of the tipping opening boundary.

So that the coupling device can reach a (drive rod) driver, it can be provided that the mounting device has a slot, which passes through the coupling device. It is understood that then also a slot in the sash or the wing flap must be provided.

If the insertion of a slot appears to be too complicated, it can be provided in an alternative embodiment that the coupling device is designed to overlap a wing flashover S-shaped.

In the context of the invention also falls a window, a door or the like with a previously described Entriegelungsanordnung.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

Preferred embodiments of the invention are shown schematically in the drawing and are explained below with reference to the figures of the drawing. It shows:

a sectional view through a fixed frame and a sash, to which a Entriegelungsanordnung according to Fig. 7 is arranged.

In the Fig. 1 For example, a window 10 is shown which includes a fixed frame 11 and a wing frame 12 of a wing. On the casement 12 an unlocking 13 is arranged. The unlocking arrangement 13 comprises a mounting device 14 designed as a base plate, which is screwed to the casement 12. Furthermore, the unlocking arrangement 13 comprises a housing 15 in which a drive arrangement 16 is arranged. The drive assembly 16 includes an electric motor drive 17, not shown, and a drive mechanism 18, which in the exemplary embodiment has a spindle 19, on which a nut 20 is guided via a thread. Accordingly, when the drive 17 drives the spindle 19, the nut 20 can be moved vertically up or down depending on the drive direction.

At the nut 20, a coupling device 21 is pivotally mounted via a pivot point 22. The coupling device 21 has a slot 23 in which a (drive rods) driver 24 of a locking fitting is arranged. About the coupling device 21 and the driver 24, the drive assembly 16 can therefore be coupled with a locking fitting not described in detail.

A portion 25 of the formed as a flat sheet metal strip coupling device 21 is guided vertically displaceable in a holding part 26 of a Kippöffnungsbegrenzung.

On the housing 15 designed as an actuating handle 30 second drive is arranged, which has a handle mandrel 31, which projects through the housing 15 and cooperates with an eccentric disk 32 formed as a translation device. The eccentric 32 is pivotally mounted on the mounting device 14.

About the unlocking 13, the coupling device 21 can be moved limited in the double arrow 33. In such a shift and the (drive rods) driver 24 is displaced in the double arrow 33. As a result, one or more locking elements 40 designed as a locking bolt can be brought into different relative positions to a closing piece 41.

A plan view of three positions of a locking element 40 relative to a striker is shown in FIG Fig. 2 shown. In the closed position, which in the Fig. 1 is shown, the locking element 40 is in the middle position 45 of Fig. 2 , This means that the locking element 40 engages behind a portion of the locking piece 41 and the wing of the sash frame 12 is locked, so it can not be opened.

In the Fig. 3 is shown a rotary opening position. For this purpose, the operating handle 30 has been rotated by 180 °. As a result of the eccentric disk 32, the housing 15 and thus also the drive arrangement 16 were displaced upward in the direction of the arrow 46. It is understood that thereby also the coupling device 21 and the Treibstangenmitnehmer 24 have been moved upwards. As a result of this displacement, the section 25 of the coupling device 21 is disengaged from the holding part 26, which is arranged on the fixed frame. In addition, by the movement of the drive rod 24, the locking element 40 in the in the FIG. 2 shown at 47 Relocated position in which this is not blocked by the locking piece 41. The wing can thus be opened in rotation without operating the drive 17.

In the Fig. 4 is a Kippbereitschaftsstellung the unlocking 13 is shown. Starting from the in the FIG. 1 shown closed position, the drive 17 has been activated such that the rotationally fixed nut 20 has been moved in the direction of arrow 50 down. As a result, the coupling element 21 and the driver 24 were moved in the direction of arrow 50 down. As a result of this measure, the locking element 40 has been moved into the position (51) ( Fig. 2 ) emotional. In the Fig. 2 a provided at the lower cross member of the fixed frame locking piece 41 is shown. This means that even in the position shown, the locking element 40 is blocked in the position 51 by the locking piece 41, since the wing must not swing down.

It can be seen that the section 25 of the coupling device 21 is still guided in the holding part 26 with its free end. During the displacement of the coupling device 21, this was also moved relative to a fixedly arranged on the mounting device 14 control part 52. The control part 52 protrudes into a control device 53 designed as a control groove Fig. 4 shown position, there was only a relative movement along the vertically aligned portion of the controller 52nd

In the Fig. 5 a tilt open position is shown. In order to get into this position, the drive 17 has been driven further, so that the nut 20 has been moved even further down. By this measure, the control part 52 reached into the inclined portion 54 of the control device 53. This had the consequence that the coupling device 21 was pivoted relative to the ver 20 ver and the tilting opening of the wing took place. It should be noted that the section 25 is still guided in the holding part 26. This ensures, in cooperation with the end stop of the control part 52 in the section 54, that the wing does not open any further. Holding part 26 and control device 53 thus represent a Kippöffnungsbegrenzung.

Here is also clear why a slot 23 is provided. Thus, the coupling device 21 can move relative to the driver 24 during pivoting between a Kippbereitschafrstellung and a Kippöffnungsstellung, without relocating it.

In the embodiment of an unlocking arrangement 60 according to the Fig. 6 the coupling device 61 is fork-shaped. The coupling device 61 is not attached to the fixed frame in this case. The Kippöffnungsbegrenzung must be accomplished otherwise. It can be seen that in the mounting device 62, a transverse slot 63 is provided, which cooperates with the eccentric disc 64. The driver 24 can be guided in the slot of the coupling device 61. The coupling device 61 is kept simpler in this case. In particular, it has no control device for opening the door. In this embodiment, therefore, for example, Ausstelleinrichtungen, in particular Ausstellscheren, must be provided, which are driven for example by the espagnolette fitting and effect the exhibition of the wing and limit.

In the FIGS. 7 and 8 a coupling device 70 is shown, which is formed substantially S-shaped, so that a wing flap 71 can be encompassed. By this measure, the unlocking 72 can be retrofitted without having to bring a slot in the mounting device 73 or the wing flap 71.
