Description

The invention relates to a device for moving a furniture flap of a piece of furniture according to the preamble of claim 1 and a piece of furniture with such a device.

State of the art

Devices for moving a furniture flap on a furniture are known in various embodiments, even under the term "upper flap fittings".

In such embodiments, the furniture flap via pivot levers, which cooperate with a guideway, from a closed state to an open state and back again defined move.

In front of the furniture to swing the furniture flap a defined space requirement is required.

In order to achieve good handling of the furniture, it is regularly sought to limit the space required for swinging the furniture flap and still allow easy and fluid movement when positioning the flap.

Purpose and advantages of the invention

The invention has for its object to improve the pivoting behavior of a furniture flap on a piece of furniture.

This object is solved by the features of claims 1 and 16.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention is based on a device for moving a furniture flap of a piece of furniture, wherein the device comprises guide means acting between a furniture body and the furniture flap, with which the furniture flap moves from a closed state relative to the furniture body in which the furniture flap moves a maximum to a front side of the furniture body Position occupies, in an open state of the furniture flap relative to the furniture body can be brought and moved back into the closed state.

The essence of the invention is that the guide means comprises a lever arrangement with a first pivot lever, which is guided guided along a first guide track, and a second pivot lever, which is guided along a second guide track movable.

By the two guideways a reproducible, precisely defined pivoting-sliding movement of the lever assembly can be achieved with a furniture flap arranged thereon. In particular, this can be used to realize an initially stronger swung-out operation of a furniture flap during an opening movement, which comprises a total of a swivel component and a linear component.

It does not happen that the linear shift share overtakes the Ausschwenkanteil so to speak.

The first guideway can be a predominant pivoting process ensure that the second guideway ensures a linear shift share. Guiding means, for example, that a guide element arranged on a lever bears against a section of the guide track and thus follows the shape of the guide track during a movement and further movement of the lever.

In a preferred embodiment of the invention, a drive arrangement is provided. The drive assembly is preferably in communication with the lever assembly. Advantageously, the drive arrangement acts on a lever of the lever arrangement in order in particular to assist the opening movement when it is initiated by an operator or, if necessary, to perform it automatically.

In a further preferred embodiment of the invention is provided as a drive arrangement Zugmittelanordnung with a tension element and a drive member for driving the tension member, wherein in a mounted state of the device, a first end of the tension member the drive member and a second end of the tension member of the furniture flap, in particular the lever assembly assigned. For example, the drive member comprises a winding element, on which the tension element can be wound up. A pulling element can be advantageously used in a device for moving a furniture flap, since in a closing direction closing forces can be provided by the weight of the furniture flap itself, so that in this direction no additional force is required by a drive.

In a further preferred embodiment of the invention, the tension element is directly connected to the first lever. This can be a simple way to initiate a tensile force on the lever assembly.

It is also advantageous if the lever arrangement is designed for mounting on opposite side walls of the carcass. Possibly. is in particular identical on two opposite side walls of the body Lever arrangement arranged. In principle, it would be conceivable that the first guide track is formed on one side and the second guide track is formed on the opposite side of a carcass. One possibility is also that the lever assembly is designed for mounting on only a single side wall.

However, in order to achieve an opposite symmetrical, simple structure, both guideways are advantageously formed on one side of the furniture body, so the first and the second guideway.

In a further preferred embodiment of the invention, the lever arrangement is linearly displaceable. For example, the lever assembly is slidably slidable on a linear track. By such a measure, a linear displacement of a furniture flap can be achieved so that, if necessary, the body in the opened state of the furniture flap is not only free for access, but the furniture flap is not protruding in front of the body, e.g. is positioned substantially or possibly completely above the furniture body relatively close to the furniture body. This is achieved in particular by the attachment of the lever arrangement on a linearly guided slide element. This also furniture flaps with comparatively large height expansion can be relocated to a furniture body to save space.

Moreover, it is advantageous if two levers of the lever arrangement are in operative connection, in particular are connected to one another in a geared manner. As a result, a lever can be used as a pull or pressure lever, whereas the other pretends a pivoting movement for swinging the furniture flap.

Preferably, two levers of the lever assembly are equipped with at least one sprocket portion, which mesh with each other during a movement. Due to the sprocket sections, the levers can be connected to each other in a gear, so that a pointer movement of the one lever results in a pointer movement of the other lever. It is also conceivable that both levers have a complete gear, the gears interlocking comb. The axes of rotation of the levers are preferably fixed to one another. For example, the tension element is arranged on a lever, while the other lever is attached to a furniture flap. Both levers are advantageously mounted on a carriage element, which can be moved linearly. Thus, a pivoting or rotational movement of the one lever, caused by the tension element via a gear transmission to a pivoting movement of the other lever for the furniture flap are transmitted, so that a pivoting movement is established and then a comparatively long linear movement is made possible via the linearly guided slide ,

It is also preferred that the lever assembly comprises a plate and the first pivot lever and another pivot lever are pivotally mounted on the plate, wherein the plate is linearly slidably received on the device. This represents a preferred embodiment of a carriage element which can be linearly displaced. By this measure, the lever assembly with plate perform a predetermined, relatively large linear displacement.

Preferably, the first pivot lever and a further pivoting lever are in operative connection, in particular are connected to each other by gear. For example, the two levers are coupled together via sprocket sections.

In a further advantageous embodiment of the invention, the second lever is guided on a backdrop. By the slide guide, for example, a clear guidance of a sliding bolt is given, without this can stand out from a guideway in a plane of the guideway. The guide pin may also be such that it is trapped by appropriate shaping of the bolt and / or the backdrop in the form, so only a movement within the backdrop is possible, especially not perpendicular thereto. Thus, a mechanical stability of the lever arrangement can be improved.

It is also advantageous if the scenery has a curved and a straight section. The curved portion serves to allow the pivotal movement of the lever assembly and thus a furniture flap arranged thereon, whereas the linear portion allows a linear displacement of the furniture flap.

In a further advantageous embodiment of the invention, the levers of the lever arrangement are coordinated such that during a movement that would cause an opening of the furniture flap, first the first lever is guided along a first guide track to the end of the guideway and in a further movement only the second lever is guided on the second guide track, whereas the first lever has separated from the first guide track. The first guide track can be used to force a pivoting movement, in which case when the pivoting movement is carried out a release of the first lever from the first guide track and the second pivot lever in the second guide track can provide the predominantly linear movement. Both pivot levers can be moved linearly after release of the first lever preferably on a carriage, wherein the further position of the second pivot lever is forced by the second guideway.

Conveniently, a displacement of the axis of rotation of the first pivot lever does not take place as long as the first pivot lever is guided on the first guide track. Preferably, then there is no displacement of the axis of rotation of the second pivot lever, wherein, however, the second pivot lever is moved about the stationary axis of rotation and thereby guided in the second guideway. Advantageously, the first guide track has a curved section which corresponds, for example, to a circular section, which ensures that the axis of rotation of the first pivot lever is not displaced during pivoting during a guide along the guide track whose center coincides with the axis of rotation.

Finally, it is preferred if the lever arrangement is arranged in a functional element, wherein the functional element either partially or completely replaces a side wall with a predefined complete wall thickness in its surface area.

FIG. 6:

a fitting part of the upper flap fitting with two tracks and a carriage guide in a perspective view.

In the FIGS. 1a to 1c the closed position of the upper flap fitting 1 is shown for example for the left side of a furniture body. FIG. 1a additionally shows hatched a bottom, a lid 3, a rear wall 4 and a furniture flap 5 of a furniture body 6. The upper flap fitting 1 is screwed eg on a side wall of the furniture body 6 via mounting holes 7 in a mounting plate 8.

The mounting plate 8 with mounting holes 7 and a guide rail 9, a slotted guide 10 and a guide rail 11 are shown in detail in FIG FIG. 6 to see.

Along the guide rail 9 runs a carriage member 12 (see in particular FIGS. 5a to 5f such as FIGS. 1a to 4a ). On slide member 12, three pivot levers 13, 14 and 15 are rotatably arranged. In the Figures 5 However, only the pivot levers 14 and 15 are shown. A mounting fitting 16 for the furniture flap 5 is seated on the pivot levers 14 and 15. The fitting 16 connects the levers 14 and 15 via pivot axes 17 and 18 (see in particular FIG FIG. 5a respectively. FIG. 2a ). The pivot levers 13, 14, 15 have pivot axes 19, 20, 21, all of which are seated on the carriage element 12. The carriage member has four profiled rollers 22 (see in particular FIGS. 5d and 5e), in which the laterally outwardly curved guide rail 9 engages when it is "threaded" between the rollers 22. So that forces perpendicular to the mounting plate 8 do not cause undesirable friction, 12 support rollers 23 are provided on the carriage member, which can run on the mounting plate 8.

On the pivot lever 15 is a link roller 24 (see, in particular FIGS. 5d and 5f ) rotatably engaged in the slide guide 10 in the assembled state runs (see Figures 1b to 4b and 1c to 4c).

On the pivot lever 13, a guide pin 25 is also provided, which runs along the guide track 11 in a portion of the pivoting movement (see in particular FIGS. 1a and 2a ).

In the FIGS. 1a and 2a the pivot lever 13 is cut out in a circular manner at the location of the guide pin 5 to make it clear how the guide pin 25 rests against the guide track 11. In the FIGS. 3a and 3b the pivot lever 13 is then fully displayed again. On the pivot lever 13, a tension element 27 is attached to one end 26, which is guided via a deflection roller 28 to a winding drive 29.

The drive of the pivot lever 13, 14, 15, in particular of the pivot lever 13, but can also be done in other ways and does not necessarily require a traction mechanism drive. In the exemplary embodiments, this is shown only by way of example.

• In den Figuren 1a bis 1c ist die geschlossene Position dargestellt. Die Kulissenrolle 24 befindet sich an einem unteren Ende 30 der Kulissenführung 10. In Figur 2 hat eine Bedienperson die Möbelklappe 5 aus der Geschlossen-Position etwas in die Geöffnet-Position gebracht, wonach der Wickelantrieb 29 ggf. unterstützend oder aber selbsttätig die Möbelklappe 5 weiter anhebt und ausschwenkt, indem der Schwenkhebel 13 vom Wickelantrieb 29 um seine Schwenkachse 19 geschwenkt wird, wodurch sich auch der Schwenkhebel 14 entsprechend verdreht, weil die Schwenkhebel 13 und 14 über Zahnkranzabschnitte 31, 32 getrieblich miteinander verbunden sind. Durch Schwenken des Hebels 14 wird die Möbelklappe entsprechend verlagert. Dieser Zusammenhang wird insbesondere in den Figuren 2a, 3a sowie 4a deutlich.

The opening and closing process of the furniture flap takes place as follows:

• In the FIGS. 1a to 1c the closed position is shown. The gate roller 24 is located at a lower end 30 of the slide guide 10. In FIG. 2 an operator has brought the furniture flap 5 from the closed position slightly in the open position, after which the winding drive 29 optionally supports or automatically raises the furniture flap 5 and pivots by the pivot lever 13 is pivoted about its pivot axis 19 by the winding drive 29 , whereby also the pivot lever 14 is rotated accordingly, because the pivot levers 13 and 14 are geared to each other via sprocket portions 31, 32. By pivoting the lever 14, the furniture flap is displaced accordingly. This relationship is particularly evident in the FIGS. 2a . 3a and 4a clearly.

In the first part of the pivoting movement of the pivot lever 13, the guide pin 25 runs along the guide track 11, wherein the guide track is formed exactly circular to a center corresponding to the pivot axis 19. Thus, the pivot lever 13 makes a pointer movement with a stationary pivot axis 19 as long as the guide pin 25 rests against the guide track 11 (see in particular FIGS. 2a . 2b and 2c ). The Pivoting movement of the pivot lever 13 causes a pivoting movement of the pivot lever 14, which is coupled via the mounting bracket 16 with the pivot lever 15 and thus also causes this to pivot, with the slide roller 24 moves away from the end 30 of the slide guide 10 from the curved portion in a proportion which is predominantly linear. Once the guide pin 25 has detached from the guideway 11 (see FIG. 3a ), the carriage member 12 can be solved from the lowest position on the guide rail 9 and moved along the guide rail 9 when the tension member 27 is further rolled up on the winding drive 29. In this case, the gate roller 24, the Ausschwenkposition the furniture flap 5 by the guide in the sliding guide 10 safely. The degree of pivoting of the pivot lever 13 and 14 is defined at this stage by the slide guide 24 moving in the slide guide 10. In FIG. 4a the upper end position of the carriage element 12 is shown. In this state, the slide roller 24 has reached an upper end 33 of the slide guide 10. In this case, the pivot levers 13 and 14 at the tooth portions 31 and 32 have allowed by a in a portion 34 of the slotted guide 10, which runs substantially parallel to a front edge of a furniture body, even further pivoted compared to a position in which the Sliding roller 24 in a portion of the slotted guide in front of a bend 35 (see in particular FIG. 3b ) of the slide guide 10 was located.

When closing the tension element 27 is unrolled from the central drive 29 and the weight force in particular the furniture flap 5, but also the movable fitting parts, in particular of the carriage member 12 with attached pivot levers 13, 14, 15 move the furniture flap by the corresponding guide to first the slide guide 10 and then at the slide guide 10 and the guide rail 11 back into an end position according to FIG. 1a , In this case, preferably, a curvature 36 (see in particular FIG. 1b and FIG. 1c ) the desired folding the furniture flap 5 in an end position sure.
