Description

The invention relates to a flap holder for a furniture flap, which is adjustable between a closing a cabinet compartment in a furniture body closing position and an upwardly moved open position, wherein the furniture flap is divided into two and is formed by an upper flap part and a lower flap part hinged to a hinge axis are connected to each other so that they are coplanar with each other in the closed position and perform in the open position opposite pivotal movements by the upper flap part away from the cabinet and the lower flap part pivots out of its upper flap part coplanar position about the hinge axis to the cabinet compartment, with at least one toggle lever assembly, with two toggle parts, which are hinged together on the one hand and on the other hand with the furniture body or with the upper flap part, wherein the toggle lever assembly is associated with a spring device, the assembled Klap Penhalter on the upper flap part when opening a force in the opening direction exerts.

Such fitting devices are used for cabinet compartments, which are either located in the upper part of a cabinet or are formed by a height-hanging overhead cabinet. If you move the furniture flap upwards, the relevant compartment will be accessible. Here is the furniture flap foldable due to its bipartite, so that the furniture flap in the open position does not project overall but only with its upper flap part upwards, while the lower flap part is folded back so to speak to the cabinet body.

Usually, the fitting device contains a guide device to be fastened on the cabinet side, in which a guide element connected to the lower end region of the lower flap part runs. This guide device extends in the mounted state on the inside of the respective side wall of the furniture body in the vertical direction. The two lateral end regions of the furniture flap are each guided by means of such a guide device, so that in each case a guide device is arranged on both side walls of the furniture body.

These guide devices represent a considerable manufacturing and assembly effort. Furthermore, they narrow the cabinet compartment.

When opening such a furniture flap must be pulled as close to the hinge axis on the lower flap part, so that the two flap parts can buckle under vertical guidance of the lower end of the lower flap part in the direction away from the furniture body. The associated handle is thus relatively high up, so that it is difficult to reach for some users.

In the DE 101 24 565 A1 a flap holder of the type mentioned is disclosed, is completely dispensed with leadership institutions. The lower flap part is connected in the assembled state only with the upper flap part, so it is otherwise free. The handle can be arbitrary be located far below the lower flap part. Furthermore, the width of the lower flap part can be arbitrarily smaller than ever since.

In the DE 100 19 337 A1 discloses a flap holder used in conjunction with one-piece flaps. The flap holder has a toggle lever arrangement, with a hinged about an articulation axis pivotally connected to the flap flap-side arm and a pivotable about a pivot axis connected to a furniture body to be fastened fitting part body side arm. At both ends of the body-side arm part are control means, each containing a pressure piece and a control cam. Pressure element and control cam are held against each other by means of a spring device. The control device serves to exert a force in the opening direction or a force in the closing direction of the flap, so that, for example, in the first case, the flap can be opened more easily or optionally remains in any open position.

The object of the invention is to provide a flap holder of the type mentioned, which is simple and allows a stable connection of a two-piece furniture flap to the furniture body.

This object is achieved by a flap holder with the features of independent claim 1. Further developments of the invention are shown in the subclaims.

The flap holder according to the invention is characterized in that at least one control lever is provided for controlling the pivoting position of the lower flap part with respect to the upper flap part, on the one hand pivotable about a first pivot axis on the furniture body and on the other a second pivot axis is pivotally fastened to the lower flap part.

By the control lever is a support of the lower flap part, so that it can no longer pivot freely about the hinge axis. This prevents that the lower flap part hangs freely in its open position and thus can inadvertently swing around in particular by manual application. Another advantage of the flap holder according to the invention is that already used in connection with one-piece flaps knee lever assemblies, such as those from the DE 100 19 337 A1 are known, can now be used for two-piece furniture flaps.

In a further development of the invention, the first pivot axis is arranged in the closed position of the furniture flap above the second pivot axis. In particular, the control lever extends obliquely forwardly below in the closed position of the furniture flap. In principle, however, it would also be conceivable that the control lever is aligned in the closed position of the furniture flap substantially parallel to the furniture flap. The body-side pivot axes or articulation points of the body-side toggle lever part or of the control lever can be varied in their position on the cabinet body. An adaptation to different cabinet compartment geometries is therefore possible. It is possible that the body-side pivot point of the toggle lever assembly and the body-side pivot point of the control lever coincide.

In a further development of the invention, the lever device associated with the spring device is designed such that in the closed position a clamping force is exerted on the furniture flap. It is therefore possible that the spring device on the upper flap part in the closed position a Locking force and when opening after overcoming a Totpunklage exerts a force in the opening direction. In principle, however, it would also be possible to design the spring device in such a way that it exerts no locking force, but the locking force in the closed position is achieved by corresponding design of the hinge between the upper flap part and the furniture body.

In a further development of the invention, the control lever is associated with a further spring device, which in addition to the spring device on the toggle lever arrangement in the closed position exerts a locking force and / or when opening a force in the opening direction. The further spring device can thus support the knee lever side spring device when opening by means of an additional force in the opening direction. The further or control lever-side spring device may be designed such that it exerts a locking force in the closed position and supports the opening of the furniture flap after overcoming a dead center. Thus, among other things, the variant would be conceivable that the knee lever-side spring device in the closed position exerts a locking force and when opening an opening force and the other, control lever side spring device also in the closed position exerting a clamping force and opening force exerts an opening force. The two spring devices can thus support each other in the locking force and the force in the opening direction. In a further preferred variant, the knee lever-side spring device exerts a force in the opening direction only when opening, while in the closed position the locking force is taken over by the control lever-side spring device.

FIGS. 1 to 4 show a preferred exemplary embodiment of the flap holder 11 according to the invention. The flap holder 11 is arranged on a cabinet, in particular a top cabinet, which is fixed in height to a building wall in a suspended manner. The body 12 of the cabinet has two opposite, vertical side walls 13, of which only one is visible in the drawing, a bottom wall 14, a ceiling wall 15 and a rear wall and contains a limited by these walls cabinet 16. The front of the cabinet compartment 16th is associated with a furniture flap 17, which occupies a vertical position in its resulting from Figure 1 closed position 18 and the cabinet compartment 16 closes. The furniture flap 17 can from this closed position 18 in an access to the cabinet 16 gestattende open position 19 (FIG 4) are adjusted, wherein the opening movement via the intermediate positions 20, 21 shown in Figures 2 and 3 takes place upwards.

The furniture flap 17 is divided into two and is formed by an upper flap part 22 and a lower flap part 23, which are hingedly connected to one another at a hinge axis E. The hinge axis E is usually formed by two each arranged on one of the two lateral end portions of the furniture flap 17 hinges, which are not shown in the drawing. The hinge may have an upper hinge part to be fastened to the upper flap part 22 and a lower hinge part to be fastened to the lower flap part 23 which are hinged to one another by means of a hinge pin or the like forming the hinge axis E. The two hinge parts can be attached to the cabinet compartment 16 facing inside of the flap parts 22, 23. The hinge axis E can be arranged near the joint between the two flap parts 22, 23 or even with a certain distance above or below the joint.

The upper flap part 22 is also still pivotable about a hinge axis F on the furniture body 12. This hinge axis F is preferably located on the ceiling wall 15 of the furniture body 12th

In the closed position 18, the lower flap part 23 connects to the underside of the upper flap part 22 in extension thereof, so that the two flap parts 22, 23 are coplanar with each other. When transferring into the open position 19, the two flap parts 22, 23 perform opposing pivotal movements by the upper flap portion 22 from the cabinet compartment 16 and thus from the furniture body 12 according to arrow 24 pivots away while the lower flap part 23 from its coplanar to the upper flap portion 22 to the position Hinge axis E to the cabinet compartment 16 and thus to the furniture body 12 out in the direction indicated by arrow 25 pivots, so that the furniture flap 17 is folded, so to speak.

At least one of the two lateral end portions of the cabinet, a toggle assembly 26 is arranged, each with two toggle parts 27, 28, on the one hand pivotable about a hinge axis B with each other and on the other hand about a body-side pivot axis A with the furniture body 12 and about a flap-side pivot axis C. are connected to the upper flap part 22.

The toggle lever assembly 26 is associated with a spring device 29 (FIG. 1) which exerts a force in the opening direction when the flap holder 11 is mounted on the upper flap part 22 when opening. The spring device 29 (FIG. 1) can, for example, be integrated into the body-side toggle lever part 27. On the other hand, however, it is also possible to use an external spring device 29, which is fixedly connected at one end to the cabinet body 12 and at the other end to the first toggle lever part 27. The spring device 29 can be formed by at least one pressure or at least one tension spring. As spring types are coil spring and / or gas spring into consideration

The spring means 29 may for example be associated with a pressure piece, which is spring-loaded at one end by the spring means 29 and the other end carries a control roller, which in turn is pressed by the pressure piece on a control cam. The cam may, for example, in the region of the hinge axis B between the two toggle parts 27, 28 are located. The control cam can be designed such that the spring device 29 in the closed position 18 of the furniture flap 17 exerts a torque on the toggle lever arrangement 26, so that a clamping force is generated. If the control roller passes over a specific dead center position given by the curve shape of the control cam, then the torque direction changes, so that a force in the opening direction is exerted from this point.

There is further provided a control lever 30 for controlling the pivotal position of the lower flap portion 23 with respect to the upper flap portion 22 which is pivotally mounted on the one hand about a first pivot axis A on the furniture body 12 and on the other hand about a second pivot axis D pivotally on the lower flap portion 23. In the embodiment shown in Figures 1 to 4 toggle assembly 26 and control lever 30 are pivotally mounted on the same body side or first pivot axis A on the furniture body 12. However, it is also possible that the body-side pivot points for the toggle lever assembly 26 and the control lever 30 are located at different locations on the cabinet body 12.

As shown schematically in Figure 1, the control lever 30 may be associated with a further spring means 31. The spring means 31 may also be assigned in a similar manner as in the toggle-side spring means 29, a control roller which is pressed via the spring means 31 to an associated control cam. The additional spring device 31, in addition to the spring device 29 arranged on the toggle lever arrangement 26, can exert a locking force in the closed position and / or a force in the opening direction when opening.

It can also be provided a compensation device (not shown) which pulls the furniture flap 17 in its closed position 18 to achieve a flap extension down. Such a balancing device is for example in the DE 10 2004 019 784 B3 described herein incorporated by reference.

The function of the flap holder 11 according to the invention when opening or closing the furniture flap 17 according to FIGS. 1 to 4 will now be explained below. By way of exemplary assumption, the toggle lever assembly 26 is provided with a knee lever spring means 29 which exerts a force in the opening direction only when opening, while the control lever 30 is associated with a further spring means 31 which supports the opening force and additionally in the closed position a locking force on the furniture flap 17 exercises:

In Figure 1, the closed position 18 of the furniture flap 17 is shown. The further spring device 31 exerts a locking force on the furniture flap 17. The control lever 30 is aligned to the bottom front. The two flap parts are in coplanar alignment with each other.

If now pulled on the lower flap part 23, for example on a handle arranged there, so pivots the furniture flap 17 total about the hinge axis F, the lower edge of the lower flap portion 23 stands out from the furniture body 12, wherein the lower flap part at the same time about the hinge axis E according to Arrow 25 pivots inwards. The lower flap portion 23 is supported by the control lever 30 so that the pivotal position of the lower flap portion 23 with respect to the upper flap portion 22 is controlled. The control lever 30 forms, together with the lower flap part 23, a further toggle lever arrangement 32, with the articulation points ADE. When the furniture flap 17 is opened, a force in the opening direction is exerted by the spring device 29 as well as by the further spring device 31 on the control lever side.

The force in the opening direction acts against the weight of the furniture flap 17 and can be dimensioned such that the furniture flap 17 remains in any open position.

Such a situation is illustrated in FIG. 2, in which the furniture flap 17 is located in a first intermediate position 20. In this intermediate position, the first pivot axis A is located above the second hinge axis D.

If the furniture flap 17 is opened further, the second intermediate position 21 shown in FIG. 3 is reached, in which the control lever 30 projects out of the furniture carcass 12 in a horizontal lever position. The axes A and D are at the same height.

Finally, the furniture flap 17 enters the open position 19 shown in Figure 4. Here, the second pivot axis D is located above the body side second pivot axis A, i. the lower edge of the lower flap part is now closer again to the furniture body 12 than in the second intermediate position 21 shown in Figure 3. In addition, the toggle lever assembly 26 is substantially fully extended with the hinge points ABC. When closing the furniture flap 17 reverse operations take place, the closing movement is supported by the flap weight. If the furniture flap again reaches the closed position 18 shown in FIG. 1, the locking force exerted by the further spring device 31 acts on the furniture flap 17.
