Description

Furniture flap drive for different flap types

The invention relates to a furniture flap drive with a first component having an electric motor and a second component having an actuating arm, wherein the first component and the second component are detachably fastened to one another and a force transmission device is provided for moving the actuating arm.

WO 2008/134786 A1 shows a flap movably mounted on a furniture body with a mechanical setting unit which has an actuating arm which can be connected to the flap and an energy store which acts on the setting arm. Furthermore, a trained as a completed component electric drive to the actuator can be fastened, the attachment is also possible when the actuator is already mounted on the furniture body.

In DE 20 2006 000 535 U1 furniture flaps are shown in different versions or types. For example, there are furniture flaps known as folding up, in which the flap is pivotally attached to the underside of the cabinet lid.

Furthermore, there are two-part executed flaps, wherein a first part flap is pivotally connected to the furniture body and a second part flap is pivotally connected to the first part flap. When transferring the flap into the open position, the first partial flap is pivoted upward away from the furniture body, wherein the second partial flap is also hinged up to the furniture body, so that the flap is folded in the open position. Such flaps have become known as Hochfaltklappen.

Another type of flap are high-pivot flaps, with the flap pivoting backwards over the furniture body.

If the flap preferably carries out a movement essentially parallel to the front side of the furniture body during its entire opening or closing path, this is referred to as a high-lift flap. This terminology should also be maintained in the context of the present invention, the list of different types of furniture flap is not meant to be understood.

In the Austrian application AT 1352/2008 a furniture flap drive is disclosed, wherein an identification device for automatic identification of the furniture flap type in the assembled state of the furniture flap drive is used to identify the respective type of furniture flap due to the measured with a measuring device opening or closing angle. This eliminates the need for manual presets on the electric motor.

Depending on the furniture flap type different mechanical actuators are used, which differ mainly in the different design of the control lever or the lever mechanism of which the lever is a part of each other 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.

Since the furniture flaps differ by different configurations of the actuating lever or lever mechanism, an attachment of a single type of electric drive to mechanical actuators for different types of flaps that are already mounted on the furniture body, only extremely difficult to carry out, especially since the different types of flaps have different opening positions, and a subsequent attachment of an electric drive is preferably carried out in the open position of the furniture flap.

A possible alternative would be to develop a separate electric drive for each mechanical actuator belonging to a particular type of damper that only fits this mechanical actuator. For economic reasons, this idea should be rejected.

The object of the invention is therefore to provide a furniture flap drive available that includes an electric drive with an electric motor and a mechanical actuator with an actuator arm, wherein electric drive and actuator as Separate fastened components are formed. This attachment is intended to be made possible in a technically simple manner, wherein the electric drive is designed such that it can be fastened to actuators for different furniture flap types.

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

An inventive furniture flap drive in this case comprises a first component, which has an electric motor and the driving force for moving the flap to

Provides. A separate second component, which has an actuating arm, and the first component are releasably fastened to one another. The actuating arm having the second component is a mechanical actuator, wherein a

Stellarm acting on energy storage is available, which is designed for example as a spring assembly. The second component, so the mechanical actuator, is mounted on the furniture body, wherein the first component can also be attached to the second component, if this is already mounted on the furniture body.

In principle, it would of course also conceivable to attach both components to each other before assembly to a furniture body together. In this case, the invention also serves to facilitate the attachment, if only one type of electric drive, so only one type of first component is to be used for actuators for different types of valves.

The actuator arm or the furniture flap of different furniture flap types set between their two end positions (closed position of the furniture flap or opening position of the furniture flap) different lengths back paths. For example, the zurücklegbare angle range at a Hochfaltklappe (HF) is about 140 °. For a high swing flap (HS), the actuator arm can cover an angular range of about 150 °, while this angle range is about 160 ° for a high lift flap (HL). These angles are each measured starting from the position at which the furniture flap on the furniture body (possibly while maintaining a slight gap to the furniture carcass to allow a touch-latch release) abuts in the closed end position, ie is in the closed position. The angle measurement can optionally also starting from a through the Pivot point of the actuator arm vertical imaginary lines done. The concrete numbers may change slightly.

Of course, the exact angles may of course vary depending on the manufacturer, or it may be possible to use other types of furniture flaps with other recumbent angle ranges. It is also conceivable that the three furniture flap types mentioned above (HF, HL, HS) have values for the traversable angular range other than those mentioned above.

If now the first component having the electric motor and the second component having the actuating arm are fastened to one another, the second component already being mounted on the furniture body, this of course can not take place in the closed position of the furniture body, but must preferably be in the open position in the end position, So in the full open position of the furniture body, done. The existing for transmitting the drive power transmission device must be connected to the actuator arm or be brought into engagement with the actuator arm. Since the position of the actuator arm in the open position but differs depending on the type of flap, the position of the power transmission device must be changed according to the flap type. For this purpose, a positioning device according to the invention is provided with which the position of the power transmission device is adjustable, so that this position refers to the type of flap used and is adjustable such that the first component, ie the electric drive on the second component, ie on the mechanical actuator, in different positions of the actuating arm can be fastened.

In this case, the first component in at least two, preferably three, different positions of the actuating arm on the second component can be fastened. The position of the power transmission device can be moved in extra provided for this purpose. By three different positions of the position of the power transmission device, the three different types of furniture flap - high lift flap, Hochschwenkklappe, Hochfaltklappe - are taken into account, for all these types of flap only one type of electric drive, so only one type of the first component, which includes the electric motor must be made , this one after Adjusting the position of the power transmission device by means of

Positioning device can be fastened to the respective mechanical actuating unit.

It may be provided that the position adjustment of the power transmission device is discrete or continuously possible. The discreet

Positional positions of the power transmission device in this case correspond to the various furniture flap types to which the first component according to the invention can be fastened. In a continuous position adjustment of the power transmission device may further be provided that the power transmission device engages in different discrete stages or different positions during the positional adjustment of the power transmission device are noticeable, again corresponding to the different discrete stages the different types of valves.

After the electric drive having the first component has been attached to the actuator arm having second component, the actuator arm of the

Power transmission device for closing and opening the flap are moved or driven. This movement of the power transmission device is of course independent of the change in position for the attachment of the two components to each other to see and of course takes place continuously.

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

Preferably, it is provided that the different position positions of the power transmission device correspond to different angular positions of the actuating arm, wherein the different angular positions preferably correspond to the opening position of the furniture flap.

In a particularly preferred embodiment, the power transmission device is arranged on the first component, while the second component has an interface, with which the power transmission device can be brought into engagement. It can be provided that the interface automatically establishes a connection to the power transmission between the electric drive and the actuator by the attachment of the electric drive to the actuator so to speak. The power transmission device can in one embodiment of the invention as Pin be formed, wherein the power transmission device, in particular the pin can be arranged on a non-circular gear, which is in operative connection with an output of the electric motor and is therefore driven to move the furniture flap by the electric motor. Preferably, the interface is formed as an exception opening on the adjusting unit, wherein the power transmission device, in particular the pin can engage in this exception opening.

In one embodiment of the invention it is provided that the positioning device has at least one stop element, with which the force transmission device is movable. Preferably, it is provided that the force transmission device is displaceably movable by the stop element.

So that the positioning device can adjust or adjust the position of the power transmission device according to the type of furniture flap used, it can be provided that the positioning device has at least one, preferably two, actuating elements.

After the first component comprising the electric motor and the second component having the actuating arm have been fastened to one another, it is, of course, intended to trigger an unwanted detachment, i. a lifting of the first component from the second component, this connection should be avoided as possible. For this purpose, in a particularly preferred embodiment of the invention, at least one locking element is provided, which preferably also actuated by the positioning device and with which the two components are fixed to one another or lockable.

Figures 13a and 13b show the components of Figure 12 in a fastened state, and Figures 14a and 14b each show a perspective view of a furniture body with a mounted furniture flap drive for a particular one

Furniture flaps type.

1 a shows a furniture flap 3 movably mounted on a furniture carcass 2 in the form of a fold-up flap (HF). The corresponding design of the furniture flap drive 1 is shown in FIG. 2a. The furniture flap drive 1 corresponds to the prior art. The angle φ is measured between two imaginary lines, one of which parallel to the longitudinal extent of the actuating arm. 4 runs. The second straight line extends at least approximately vertically and through the pivot point of the actuating arm 4. On the plate 5, the furniture flap 3 shown in Fig. 1a can be attached. FIGS. 1b and 2b show the corresponding representations for a high-pivoting flap (HS). FIGS. 1c and 2c show the corresponding illustrations for a high-lift flap (HL).

It can be seen that due to the different geometrical course of movement of the furniture flap 3, the exact construction of the lever mechanism is different. However, the electromotive driving the movement of the furniture flap 3 takes place in each case by the actuating arm 4, which is moved by means of a power transmission device 11. The furniture flap drive 1 in each case comprises the two components 7, 8 which can be fastened to one another in a detachable manner. The electric motor and the corresponding electronic circuits are arranged in the first component 7, which represents the electric drive. The actuator arm 4 acting on energy storage, which is usually designed as a spring assembly is housed in the second component 8.

FIGS. 3a to 3c each show a side view of an embodiment of a second component 8 (mechanical actuating unit). Depending on which furniture flap type is to be used, a corresponding second component 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 second component 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 first component 7 with the Interface 9 engageable and both are during the Öffnungsbzw. Closing movement along the guideway 10 moves.

FIG. 3c shows a second component 8 for moving a high-lift flap (HL). 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 brought into engagement with the interface 9.

During the opening and closing movement, both move along the guideway 10.

The difficulty in securing the first component 7 to the second component 8 can be seen with reference to FIGS. 3 a to 3 c, if only one type of first component 7 is to be used for different embodiments of the second components 8. If the second component 8 already attached to the respective furniture body 2 and the first component 7 is subsequently attached to the second component 8, this is preferably done in the open position of the furniture flap 3. In the open position, however, the interface 9 is at different opening angles φ, whereby the Location of the power transmission device 11 must be adjusted accordingly. This positional adjustment is done with a positioning device 12 according to the invention.

In a perspective view, a first component 7, that is, an electric drive is shown in Fig. 4, which is releasably attachable to various embodiments of the second component 8. For releasable attachment serve next to a centering pin 15 which can be inserted into an associated exception opening 26 in the second component 8, two retaining lugs 16 which bear against corresponding surfaces of the second component 8. These surfaces serve as stop elements or holding elements. The first component 7 has the power transmission device 11, which is inserted into the formed as an exception opening interface 9 and thereby brought into engagement. The positioning device 12 is provided with an actuating element 13, with which the power transmission device 11 is movable. From the positioning device 12, the power transmission device 11 is partially displaced along an exception opening 17 in the housing of the first component 7 by actuation of the actuating element 13. Hook-shaped projections serve as Locking elements 14 for fixing or locking the fastened components 7,8.

In FIG. 5, the detail marked A in FIG. 4 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",

By a displacement of the actuating element 13 and the power transmission device 11 is displaced, wherein the power transmission device 11 is partially displaced along the exception opening 17.

For mounting on a Hochfaltklappe (HF), the actuator 13 and thus the power transmission device 11 is moved furthest along the exception opening 17, since this type of flap has the smallest opening angle φ of the three types of flap shown. To close the fold-up flap, the power transmission device 11 moves from this starting point, ie from the position marked "HF", down along the exception opening 17 and thereby guides the actuating arm 4 with it.

The high-lift flap has the largest opening angle φ, so that in order to fasten the first component 7 on the second component 8, the force transmission device 11 in this case has to be displaced least along the guide track 17. 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 first component 7 is attached to the second component 8, previously manually

Actuator set to the respective flap type. It can be provided that the positioning device 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 such that it can be inserted into the formed as an exception opening interface 9 on the optionally already mounted second component 8.

After attachment of the two components 7, 8 to each other, the actuating element 13 can be moved to a further position. This position is marked "LOCKED" on the marking surface 18. By moving the actuating element 13 to this position, two locking elements 14 designed as hook-shaped projections on the positioning device 12 are displaced to a position at which they are provided with stop or stop elements As a result, the two components 7, 8 can no longer be detached from one another because a lifting of the first component 7 from the second component 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, the positioning device 12 can be seen, which has two opposing actuating elements 13. By a displacement of the actuating elements 13, the positioning device 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 positioning device 12 formed as hook-shaped projections cantilevered 14 are arranged. 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 Fig. 7 shows again the essential components of the invention. On the non-circular gear 19, the power transmission device 11 is arranged. The positioning device 12 has stop elements 12 ', which are displaced by actuation of the actuating elements 13 and thereby displace the power transmission device 11. On the housing 22 of the first component 7, the markers for the corresponding types of valves are arranged. 8b, which shows an embodiment of the first component 7 in a side view, shows how the actuating element 13 of the positioning device 12 is arranged in the position marked for the fold-down flap. The stop element 12 'of the positioning device 12 has thereby displaced the power transmission device 11 in a corresponding position. The locking element 14 is arranged in an exception opening 23 of the housing 22.

Now, if the components 7 and 8 are fastened to each other, the actuating element 13 is displaced to the position marked "LOCKED", as shown in the detail view of FIG. 9b of the section marked with C in FIG Actuator 13, the positioning device 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.

FIG. 10 shows a perspective detail view of the components 7 and 8 fastened to one another. It can be seen as the power transmission device 11, which is designed as a pin formed in the exception opening interface 9 has been inserted and thereby came 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 components 7 and 8 are correctly fastened to each other or locked.

FIGS. 11a to 11c, in turn, show the components 7 and 8 fastened to each other. As can be seen, the locking elements 14 are provided with corresponding abutment means. Retaining elements 25 in engagement. Likewise, the power transmission device 11 is engaged with the interface 9.

In the perspective view 12a and in the plan view 12b can be seen as the two components 7 and 8 after the positioning device 12 by means of

Actuator 13, the power transmission device 11 has moved to the appropriate position for the respective flap type, are attached to each other. through the retaining lug 16, the first component 7 is suspended in the second component 8. Those surfaces or edges of the second component 8 against which the retaining lugs serve serve as a bearing point about which the hinged first component 7 can be pivoted toward the second component 8. In the opening 26 in the second component 8 of the centering pin 15 can be inserted. This connection is used for play-free positioning of the components 7,8.

The positioning device 12 together with the locking elements 14 and the associated stop or holding elements 25 serve as a locking device remote from the bearing, by means of which, the first component 7 with the second component 8, preferably releasably, can be locked. This condition is shown in Figs. 13a and 13b

14a 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 FIGS. 3 to 13. FIG. 14b shows a perspective detail view of FIG. 14a in another viewing direction.

The invention is not limited to the examples shown, but includes all technical equivalents, which may fall within the scope of the following claims.

Also, the location information chosen in the description, such as top, bottom, side, etc. referred to the immediately described and illustrated figure and are mutatis mutandis transferred to the new situation in a change in position.
