Description

The invention relates to a furniture flap drive with an electric motor having an electric drive and a control arm having mechanical actuating unit, wherein the mechanical actuator and the electric drive are separate components and are releasably fastened together.

The WO 2008/134786 A1 discloses the features of the preamble of claim 1 and shows a movably mounted on a furniture body flap with a mechanical actuator, which has a connectable to the flap actuating arm and an actuating arm acting on energy storage. Furthermore, a trained as a separate component electric drive to the actuator can be fastened, the attachment is also possible when the actuator is already mounted on the furniture body.

Depending on the type of furniture flap different mechanical actuators are used, which differ from each other, especially in the different design of the control lever or the lever mechanism, of which the lever is a part in order to perform the respective characteristic movement of the furniture flap. The mechanical actuator is usually also always provided with a spring assembly, which serves to balance the weight of the furniture flap within certain limits or to balance out.

The arrangement of the mechanical actuating unit on the furniture body can be carried out at different points of the furniture body. This can lead to situations, especially when the corresponding furniture carcasses are arranged at overhead height, where a subsequent attachment of the electric drive is difficult to carry out. This applies all the more if, as usual, the electric drive is bolted to the actuator, for which through holes are provided in the actuator and the electric drive.

The object of the invention is therefore to avoid this disadvantage and to provide a simple fixation option for the attachment of the electric drive to the actuator.

This object is achieved by a furniture flap drive with the features of claim 1.

The furniture flap drive according to the invention has an electric drive which comprises an electric motor and is designed as a separate component from the mechanical setting unit which comprises an actuating arm. Both components, i. the electric drive and the mechanical actuator are detachably fastened to each other, wherein the electric drive can be fastened to the actuator even if the actuator is already mounted on the furniture body. This also allows the replacement of a defective electric drive without having to remove the mechanical actuator from the furniture body.

By now the actuator has a bearing in which the electric drive can be suspended, a first coarse positioning of the electric drive on or on the actuator unit is possible without that any screws must be inserted into through holes. By now further provided that the hinged electric drive to the actuator is pivoted out, the actuator can already be mounted on the furniture body, starting from the hinged electric drive allows a more accurate positioning of the electric drive by a simple pivoting movement. By this pivoting movement of the electric drive and the actuator can already be connected to each other.

To release, i. a lifting, to prevent the electric drive from the actuator, a remote from the bearing locking device is provided, which allows a fixation of the actuator connected to the electric drive, wherein the electric drive is locked after pivoting on the actuator with this. It is provided that the locking means comprises means with which the lock is releasable. In this case, the locking device can have components arranged on or on the electric drive as well as components arranged on or on the actuating unit.

Instead of having to use a number of mounting screws for fixing the electric drive on the actuator in a complicated manner, which may need to be screwed in hard to reach positions, the attachment and optionally also a fixation of the electric drive to the actuator according to the invention in a simple manner by a movement with the the electric drive can be suspended on the setting unit and allows a subsequent pivoting movement in the suspended state. The locking device has a locking element and a corresponding holding element or stop element, wherein the locking element can be brought into engagement with the holding element or stop element. In this case, the locking element may be arranged on or on the electric drive and the associated holding element on or on the setting unit or vice versa. In this case, the locking element can be moved in at least two positions, wherein one of the positions a locking position is in which the locking element with the holding element or stop element is engaged in such a way that lifting or releasing the electric drive from the actuator is no longer possible. The other position is an unlocking position, in which an arrangement of the electric drive on the actuating unit for fixing these two components or a renewed detachment of these components is possible.

According to the invention it is provided that the at least one locking element is rotatably mounted, and by rotation with the associated holding element or stop element is engageable. In this case, that locking element can be actuated by an actuating device, wherein this actuating device is arranged on or on a locking lever, which is part of the locking device and can itself be rotatably mounted. The locking device can be moved by the locking lever in the corresponding Verriegelungspoistion. Also, a movement in an unlocked position may be possible.

Further advantageous embodiments of the invention are defined in the dependent claims.

In a preferred embodiment of the invention, the setting unit has a short axis which is arranged perpendicular to a long axis of the setting unit, wherein the long axis of the setting unit points in the direction of the longitudinal extent of the setting unit. The short axis thus points in the direction of the transverse extent of the setting unit, which is shorter than the longitudinal extent. It is now envisaged that the hinged electric drive is pivotable about the short axis to the actuator unit. The short axis can be arranged substantially vertically in mounting position of the actuator.

This embodiment is particularly advantageous when the actuator is already mounted on the side wall of the furniture body and is therefore particularly in mounting position. The short axis can be aligned parallel to the side wall and the rear wall of the furniture body to which the adjusting unit is attached. In general, mechanical actuating units for furniture flaps are designed such that the actuating arm is arranged in the front part, ie in the region of the furniture flap to be opened, and extends longitudinally in the rear region of the furniture body. Subsequent installation of an electric drive can therefore be made more difficult, especially with furniture flaps arranged at a high level, with adjusting units having a longitudinal extent. If the bearing point, which is remote from the locking device, arranged in the rear region, this pivoting about the short axis of the actuator is particularly advantageous because the electric drive must be hung only in areas of short transverse extent and the pivoting movement in this case in the direction of preferably arranged in the front region locking device can be done. This facilitates a subsequent arrangement of an electric drive to the actuator.

In one embodiment of the invention, the locking device is designed as a mechanical latching connection. For this purpose, it can be provided that the locking device has a latching element which is arranged on the electric drive or on the setting unit and can then be brought into engagement with a holding element arranged on or on the setting unit or the electric drive. The holding element is thus on the respective other of these components, on or on which the latching element is arranged, arranged. If the latching element is arranged on the electric drive, an associated holding element is arranged on the setting unit and vice versa.

In this case, it is particularly preferred that the mechanical latching connection is self-latching. For this purpose, it can be provided that the latching connection forms a snap connection, and the electric drive is locked on the actuating unit by the corresponding components of the locking device are brought by pressure in the direction of the pivoting movement into engagement. In the region of the locking device, the electric drive can be aufklippsbar on the actuator. The locking device may have a touch-latch functionality, so be solved by further pressure on the electric drive in the direction of the actuator again.

An optionally present latching element is self-latching in a corresponding holding element latching or self-locking engageable by the latching element is pressed onto the holding element. A possible embodiment of such a latching element is a latch.

For this purpose it can be provided that parts of the locking device, so for example, the locking element, is resilient or spring-loaded. It can further be provided that the latching connection can be brought by pressure against the spring force action disengaged. As a result, the locking device can be made detachable and the electric drive is unlocked from the setting unit and finally released or lifted off.

The bearing is located away from the locking device. In one embodiment of the invention it is provided that the bearing point has at least one stop element, which may be formed, for example, as a stop edge. This stop element can be brought into engagement with one or more corresponding retaining lugs, which are arranged on the electric drive. For this purpose, the retaining lugs are so moved over or into the stop elements, so that the electric drive is mounted in the setting unit and can be pivoted about this position. The retaining lugs are supported on the stop elements. In principle, the reverse arrangement is possible, wherein the retaining lug or the retaining lugs are arranged on the actuating unit and the stop elements on the electric drive. The retaining lug or the stop elements are used for the suspended electric drive as holding elements.

In a further embodiment of the invention, the setting unit or the electric drive has a centering device, so that when attaching the electric drive to the adjusting unit no play can occur and the components can be positioned exactly to each other. It can be provided that the centering device comprises a centering pin and the centering pin corresponding exception opening, wherein the centering pin on the electric drive and the exception opening in the actuator or vice versa are arranged.

The invention further relates to a piece of furniture with a furniture body and a flap movably mounted on the furniture body, wherein an inventive furniture flap drive is arranged on one or both sides of the furniture body and the actuating arm of the furniture flap drive is connected to the flap.

It can further be provided that on both sides a mechanical actuator with power storage and actuator arm is arranged, but only one of these actuators is connected to an electric drive according to the invention.

Fig. 1 shows a side view of a furniture flap drive 1, which is mounted on a furniture body 2 and comprises a mechanical actuator 8 and an electric drive 7. The mechanical actuating unit 8 has an actuating arm 4, which in turn comprises a plate 5, on which a furniture flap 3 can be fastened. The opening angle φ is measured between two imaginary lines, one of which runs parallel to the longitudinal extent of the actuating arm 4. The second straight line extends at least approximately vertically and through the pivot point of the actuating arm 4.

The actuator arm 4 is acted upon by a force accumulator, which is usually designed as a spring assembly. The mechanical actuator 8 and the electric drive 7 itself are known per se in the prior art and therefore need not be explained in detail.

This embodiment of the lever mechanism of the adjusting unit 8 serves as a so-called Hochschwenkklappe, in which the furniture flap 3 is pivoted over the furniture body 2 away to the rear. Of course, the invention is also applicable to other types of valves, such as so-called Hochfaltklappen or high lift doors. Such types of valves are known per se in the prior art and are used for example in the DE 20 2006 000 535 U1 explained in more detail.

In Fig. 2a schematically the principle of operation of the invention is shown. The electric drive 7 has means with which it can be suspended in the control unit 8. The adjusting unit 7 is already mounted on the furniture body 2. The attachment of the electric drive 7 takes place in the rear region of the adjusting unit 8, on the rear wall of the furniture body 2 facing side, which would be difficult to access for a screw. The hanging itself is, however, easy to carry out. The electric drive 7 suspended in the setting unit 8 is then pivoted in the direction of the arrow towards the setting unit 8, wherein the pivoting takes place about the bearing point 28 at which the electric drive 7 is suspended in the setting unit 8. The electric drive 7 has a power transmission device 11 which transmits the force provided by the electric motor to the setting unit 8 and thereby moves the setting arm 4 for the opening or closing movement. A centering pin 15 serves to center the electric drive 7, so that it can be exactly positioned and clearance connected to the setting unit 8. The hinged electric drive 7 is mounted around the short axis, which is parallel to the side wall and rear wall of the furniture body 2, in the direction of mounted Actuator 8 pivoted. The locking device 27 is arranged in the front region of the furniture body, while the bearing 28 is arranged in the rear region. As a result, the electric drive 7 suspended in regions of the transverse extension in the rear area of the setting unit 8 is given away around the short, in this case vertically arranged axis of the setting unit 8, wherein the pivot points are arranged in the rear area of the furniture body 2. Such an embodiment facilitates a subsequent arrangement of the electric drive 7 on the setting unit 8, since a hooking is necessary only in areas of the transverse extent of the adjusting unit 8.

In Fig. 2b is shown schematically how now the electric drive 7 and the actuator 8 are connected after the electric drive has been 7 pivoted to the actuator 8 out. A locking device 27 serves to lock the actuator 8 and the electric drive 7 in this position, so to fix.

The Fig. 3a to 3c each show in a side view an embodiment of a mechanical actuator 8. Depending on which furniture flap type is to be used, a corresponding actuator 8 is used.

In Fig. 3a a mechanical actuator 8 is shown for a pop-up. The zurücklegbare angle range from the closed position to the open position of the furniture flap 3 is 143 ° in this embodiment. The trained as an exception opening in the actuating arm 4 interface 9 is located in that position in which the furniture flap 3 and the actuating arm 4 is in the open position. With the interface 9, the power transmission device 11 can be brought into engagement. For the opening and closing movement of the actuating arm 4, the interface 9 and the power transmission device 11 move along the guideway 10.

The actuator 8 of Fig. 3b serves to move a high-pivoting flap (HS). The zurücklegbare angle range in this embodiment is 151 °. The trained as an exception opening in the actuator arm 4 interface 9 is in that position in which the furniture flap 3 and the actuator arm 4 is in the open position. Again, the power transmission device 11 of the electric drive 7 is engageable with the interface 9 and both are moved along the guide track 10 during the opening and closing movement.

In Fig. 3c an actuator 8 for moving a high lift flap (HL) is shown. In this embodiment, the zurücklegbare angle range is 161 °. Again, the trained as an exception opening interface 9 is in that position in which the furniture flap 3 is in its open position. The power transmission device 11 is engaged with the interface 9. During the opening and closing movement, both move along the guideway 10.

In the open position, the interface 9 is depending on the type of flap used at different opening angles φ, whereby the position of the power transmission device 11 must be adjusted accordingly to be brought into engagement with the interface 9. This positional adjustment is done with a locking lever 12, which is part of the locking device 27 and brings locking elements 14 with associated holding elements 25 in engagement.

In a perspective view is in Fig. 4 an electric drive 7 is shown, which is releasably attachable to various embodiments of the actuator 8. For releasable attachment serve next to a centering pin 15 which can be inserted into an associated exception opening 26 in the actuator 8, two retaining lugs 16 which abut against corresponding surfaces and edges 28 ', 28 "of the actuator 8 and partially supported there Surfaces and edges serve as stop elements or stop edges 28 ', 28 "and form by the support at the same time a bearing 28, in which the electric drive 7 can be suspended and the electric drive 7 is pivotable. The stop elements or stop edges 28 ', 28 "serve as holding elements for the retaining lugs 16 of the electric drive 7 as soon as it is suspended in the setting unit 8.

The adjusting unit 8 has the power transmission device 11, which is inserted into the formed as an exception opening interface 9 and thereby brought into engagement. The lock lever 12 is provided with an actuator 13 with which the power transmission device 11 is movable. By operating the actuating device 13, the power transmission device 11 is partially displaced along an exception opening 17 in the housing of the electric drive 7 by the locking lever 12. The locking lever 12 is part of the locking device 27 and has locking elements 14 designed as hook-shaped protrusions for fixing or locking the electric drive 7 to the setting unit 8.

In Fig. 5 is the in Fig. 4 A section marked A is shown in a perspective view. The actuator 13 can be moved to different positions. These positions are marked on a surface 18 ("HL", "HF", "HS", "LOCKED") and indicate the various types of flap as well as the locking position. The first three positions are unlocked positions in which an arrangement and a detachment of the electric drive 7 to or from the setting unit 8 is possible. By a displacement of the actuating device 13 of the locking lever 12 is actuated, on the one hand, the power transmission device 11 moves to adapt to the different positions of the interface 9 yes furniture furniture type, wherein the power transmission device 11 is partially displaced along the exception opening 17. On the other hand, by a rotation of the locking lever 12 and the locking elements 14 are moved in a housing recess 23.

For mounting on a fold-up flap (HF), the actuator 13, and thus the power transmission device 11 for attachment of the electric drive 7 at the Stelleineinheit 8 farthest shifted along the exception opening 17, since this type of flap has the smallest opening angle φ of the three types of flap shown. In order to close the fold-up flap, the power transmission device 11 moves with the actuating arm 4 from this starting point, that is to say from the position labeled "HF", downwards along the exception opening 17.

The high-lift flap has the largest opening angle φ, so that the force transmission device 11 in this case has to be displaced least along the guide track 17 for fastening the electric drive 7 on the setting unit 8. In order to close the high-lift flap, the power transmission device 11 moves with the actuating arm 4 from this starting point, that is to say from the position marked "HL", downwards along the exception opening 17.

In between is the mark for the Hochschwenkklappe. To close the upper flap, the power transmission device 11 moves with the actuating arm 4 from this starting point, that is, from the position marked "HS", downwards along the exception opening 17.

Now, if the electric drive 7 is mounted on the control unit 8 and pivoted to this, the actuator is manually adjusted to the respective type of flap previously. It can be provided that the locking lever 12 and the actuator 13 engages at the respective position or this position is noticeable when moving. With the displacement, the power transmission device 11 is displaced so that it can be inserted into the trained as an exception opening interface 9 on the optionally already mounted on the furniture body 2 actuator 8.

After attachment of the two components 7, 8 to each other, the actuator 13 can be moved to the locking position. This position is marked "LOCKED" on the marking surface 18. By moving the actuating device 13 to this position, two locking elements 14 formed as hook-shaped protrusions on the locking lever 12 are displaced to a position in which they engage with stop or holding elements 25 of the setting unit 8 provided for this purpose, which form a further part represent the locking device 27. As a result, the electric drive 7 can no longer be released from the setting unit 8, because lifting of the electric drive 7 from the setting unit 8 by the locking elements 14 and the stop or holding elements 25 is prevented. Only when the actuator 13 is removed again from the "LOCKED" position, a detachment is possible.

In the partially broken perspective view of Fig. 6 is the rotatably mounted locking lever 12 to see, which has two opposing actuators 13. By a displacement of the actuators 13 of the locking lever 12 is rotated, whereby stop elements 12 'move and thereby move the power transmission device 11 slidably. The power transmission device 11 in turn is arranged on a non-circular gear 19. On the locking lever 12 formed as a hook-shaped protrusions locking elements 14 are arranged, which are rotated at a rotation of the locking lever 12. A loaded by a spring 21 display device 20 is used to indicate whether the two components 7, 8 are correctly fastened or locked together.

The exploded view of the Fig. 7 shows the components for the lock. On the non-circular gear 19, the power transmission device 11 is arranged. The locking lever 12 has stop elements 12 'and locking elements 14, which are displaced by actuation of the actuators 13. On the housing 22 of the first component 7, the markings for the corresponding flap types and the locking position are arranged.

In the in Fig. 8b shown detail view of the marked B section of the Fig. 8a showing in side view an embodiment of the electric drive 7 is shown how the actuator 13 of the locking lever 12 is arranged in the position marked for the pop-up flap. The stop element 12 'of the locking lever 12 has thereby shifted the power transmission device 11 in a corresponding position. The locking member 14 is disposed in an exception opening 23 of the housing 22 and is not engaged with the stopper member 25.

Now, if the electric drive 7 and the actuator 8 are secured together, the actuator 13 is moved to the marked "LOCKED" position, as shown in the detail view of Fig. 9b of the section marked C with the Fig. 9a is shown. By this displacement of the actuating device 13, the locking lever 12 and thus the locking elements 14 has been rotated, whereby this has been brought into engagement with corresponding stop or holding elements 25 of the second component 8, so that lifting the electric drive 7 from the setting unit 8 is no longer is possible.

In Fig. 10 is a perspective detailed view of the components 7 and 8 attached to each other. It can be seen as the power transmission device 11, which is designed as a shaft journal, formed in the exception opening interface 9 is inserted and thereby brought into engagement with this. The electric motor now moves the power transmission device 11 along the guideway 10, whereby the actuating arm 4 is moved accordingly. In an exception opening 24 of the housing, the display device 20 can be seen, which indicates whether the electric drive 7 and the actuator 8 are correctly fastened or locked together. For game release the centering pin 15 is inserted into an associated exception opening 26.

The Fig. 11a to 11c again show the attached components 7 and 8. As can be seen, the locking elements 14 with corresponding stop or holding elements 25 are engaged. Likewise, the power transmission device 11 with the interface 9 and the retaining lugs 16 with stop elements or stop edges 28 ', 28 "engaged and are supported on the stop elements or on the stop edges 28', 28" and the stop edges 28 ', 28th "adjacent surfaces of the actuator 8 from.

In Fig. 12a is shown the situation in which the electric drive 7 and the actuator 8 are still completely separated. The Fig. 12a shows this in a perspective view, while Fig. 12b represents a top view of this situation. The electric drive 7 in this case has two retaining lugs 16, which are engageable with abutment edges 28 ', 28 "and with the abutment edges 28', 28" adjacent, serving as a stop elements surfaces of the actuating unit 8 in engagement. As stop edges 28 ', 28 "serve both the end edge 28' of a horizontal web 29 and the perpendicular thereto arranged edge 28". The edges 28 ', 28 "and the adjoining surfaces of the adjusting unit 8, against which the retaining lugs 16 serve as stop elements and as a bearing 28 to which the electric drive 7 for adjusting unit 8 is pivoted, with the retaining lugs 16 on the stop elements support.

Fig. 12c shows a detailed perspective view of one of the retaining lugs 16 with the associated abutment edges 28 ', 28 ", which are formed both as an edge of the horizontal web 29 and the perpendicular thereto, wherein the retaining lugs 16 abut in the suspended state of the electric drive 7 and on these surfaces , in particular for the pivoting movement, which thus serve together with the abutment edges 28 ', 28 "as a bearing 28.

Another perspective view is in Fig. 12d shown. Here is particularly well serving as a stop or holding element horizontal web 29 and the stop edges 28 ', 28 "recognizable.

In Fig. 13a is to be seen in a perspective view of how the electric drive 7 and the actuator 8 are at least partially connected, wherein the retaining lugs 16 with the stop elements, in this case from the horizontal web 29 and the perpendicular thereto arranged transverse surface and the stop edges 28 ', 28 "formed In this state, the electric drive 7 is suspended in the setting unit 8. Those areas on which the retaining lugs 16 rest, serve as a bearing 28 to which the electric drive 7, starting from the state shown here now to the setting unit is pivoted.

Fig. 13b shows this state in a plan view while Fig. 13c in a perspective detailed view shows how one of the retaining lugs 16 abuts both the horizontal web 29 and on the transverse surface arranged perpendicular thereto. This is also in the perspective view of Fig. 13d to see.

In the Fig. 13e in the perspective detail view, a part of the locking device 27 can be seen, which comprises a locking lever 12 with arranged locking elements 14 which are arranged on or in the electric drive 7. By actuating the locking lever 12 by means of the actuating device 13, the locking elements 14 come into engagement with retaining elements 25. A arranged on the electric drive 7 centering pin 15 is inserted during the pivoting movement in an opening 26 of the adjusting unit 8 and serves as a game release. The power transmission device 11 is inserted into a formed as an exception opening 9 interface. During the opening or closing movement, the power transmission device 11 moves along the guide track 10, thereby moving the actuator arm 4 for opening or closing the furniture flap third

In Fig. 14a are the control unit 8 and the electric drive 7 of the furniture flap drive 1 in the connected state shown in perspective. Fig. 14b shows this in a plan view.

In Fig. 14c in turn, the bearing is shown, against which the retaining lugs 16 of the electric drive 7 abut against stop elements. Fig. 14d shows this in a further perspective view. It can also be seen how the power transmission device 11 in the guideway 10, in which the power transmission device 11 is movable, is arranged. The centering pin 15 is arranged in the associated exception opening 26.

Fig. 14e shows in a perspective detailed view of how the locking device 27 locks the actuator 8 and the electric drive 7 in the connected position. By the locking lever 12, the locking elements 14 have been moved so that they have been brought into engagement with stop elements 25, so that a detachment, ie a lifting of the electric drive 7 is prevented by the setting unit 8. The centering pin 15 is inserted into the associated exception opening 26.

Fig. 15a shows a furniture body 2 with a movably mounted furniture flap 3 in the form of a fold-up flap and a furniture flap drive 1 according to the Fig. 1 to 14 , Fold up flaps are two-part designed flaps 3, wherein a first part flap is pivotally connected to the furniture body 2 and a second part flap is pivotally connected to the first part flap. When transferring the flap 3 in the open position, the first part flap is pivoted upward from the furniture body 2, wherein the second Part flap is also hinged up to the furniture body 2, so that the flap 3 is folded in the open position.
