Abstract

The fitting has a joint (93) formed in a region of a hinge (89) between folding parts. A movable furniture piece is guided over the fitting between opened and closed positions under co-operation of a control unit that exhibits a control lever (94). The folding parts are performed during conversion of unfolding movement in the closed position to reduce joint width. An overload clutch (112) is attached to the control unit, and decouples an overload under neutralization of a positive guide caused by the control unit based on the blockage of the unfolding movement.

Description

The invention relates to a furniture fitting for a movable furniture part, such as folding flap, folding door o. The like., Wherein the Faltmöbelelement has a first folding part and a second folding part, which are hingedly connected to each other by means of a hinge axis having a hinge, wherein in the region of the hinge between the first and the second folding part a joint is formed with a joint width, and wherein the movable furniture part on the furniture fitting between an open and closed position with the assistance of a control lever having control device is forcibly guided, wherein the two folding parts when transferring into the closed position, reducing the joint width of the joint Perform unfolding movement.

In moving furniture parts, such as folding flaps, folding doors or the like, which have two relatively movable folding parts, there is a risk that fingers of a user come into the joint between the two folding parts and thereby be trapped when closing the Faltmöbelelements.

To counteract this problem, so-called finger protection hinges are already known from the prior art. In the EP 1 727 954 B1 For example, such a finger guard hinge is described, which is designed as Einachsscharnier and a hinge part in the form of a hinge arm and a further hinge part in the form of a hinge cup, wherein the hinge cup-like hinge part is attached to the one flap part of a folding flap and the hinge arm-like hinge part on the other flap part. The hinge arm-like joint part is mounted on a mounting plate and mounted there displaceable and perpendicular to the hinge axis. Further, a spring is provided, which is supported on the mounting plate and the hinged arm-like joint part acted upon such that the two partial flaps occupy their normal position with the folding flap closed, ie the joint between the two partial flaps is relatively narrow. If someone closes the folding flap with his fingers in the gap between the two partial flaps, then the spring gives way and the partial flaps are pushed away from each other, ie the joint is enlarged.

The object of the invention is to provide a furniture fitting of the type mentioned in the conventional hinges can be used to connect two folding parts of a movable furniture part and still a finger protection is realized on the movable furniture part.

The object is achieved by a furniture fitting with the features of independent claim 1. Further developments of the invention are shown in the subclaims.

The furniture fitting according to the invention is characterized in that the control device is associated with an overload clutch, which decouples at a occurring due to a blocking of the deployment movement overload while canceling the caused by the control device forced operation.

Compared to the prior art, therefore, a very different approach for preventing the pinching of a user's fingers chosen as known in the art by finger guard hinges. When furniture fitting according to the invention conventional hinges can be used to connect the two folding parts of a movable furniture part or Faltmöbelelements that are not modified for finger protection, as is known for example from the aforementioned prior art. The finger guard is realized in the area of the control device with the control lever, in which disengages an overload clutch in case of overload. As a result, the positive guidance of the two folding parts is canceled, so that the joint width of a gap between these two folding parts when closing can not be reduced. The pinching of the user is prevented.

In a further development of the invention, the overload clutch between two in the disengaged state relatively movable control lever parts of the control lever is effective. It would be possible, for example, that the two control lever parts are connected to each other via a solid-state joint, which buckles in case of overload.

It is preferred, however, that the control lever parts are designed as separate components that perform a positive guidance of the movable furniture part canceling such translational movement to each other during disengagement of the overload clutch that the two folding parts are moved while maintaining the joint width as a kind of rigid arm. After disengaging so the angular position of the two folding parts to each other and thus the joint width no longer changes.

In a particularly preferred manner, one of the two control levers is designed as a kind of coupling piece, on which the other Control lever part by means of coupling means belonging to the overload clutch in the coupled state form and / or force or frictionally held. The engaged state can therefore be realized by means of form or force or frictional engagement of the two control lever parts.

It is expedient that the coupling means comprise a guide housing formed on the coupling piece for guiding the other control lever part and on the one hand on the coupling piece and on the other hand on the other control lever part formed latching means which are locked together in the coupled state. The locking means may for example be formed by a preferably formed on the coupling piece spring-mounted locking tongue and a preferably formed on the other control lever part complementary locking opening.

In a further development of the invention, the control device on a folding parts attachable control lever bearing on which the control lever is pivotally mounted by means of a pivot axis, wherein the overload clutch between the control lever bearing and the associated folding part is effective. In this case, the overload clutch does not act between the two control lever parts, but between the control lever and the control lever bearing.

In a further development of the invention, the control lever is articulated via a body-side pivot axis to a steering lever, which in turn is pivotally mounted in the furniture mounted state of the furniture fitting with respect to the furniture body by means of a steering lever pivot axis.

In a further alternative position of the overload clutch, it is possible that this is effective between the control lever and the steering lever. In principle, it would even be possible to have one to combine between the two control lever parts effective overload clutch with an effective between the control lever and the control lever bearing overload clutch or with an effective between the steering lever and the control lever overload clutch. A combination of an overload clutch between the control lever and the control lever bearing with an overload clutch between the steering lever and control lever is possible.

In a further development of the invention, the furniture fitting a hinge assembly, in particular multi-joint arrangement with several hinged together and mutually pivotable joints, which connects in the furniture mounted state of the furniture fitting one of the two folding parts with the furniture body.

The articulated arms of the joint arrangement may comprise a first support arm and a second support arm and a fastened to one of the two folding parts holding part, wherein the two support arms pivotally on the one hand to first and second body side pivot axes on the furniture carcass or on a furniture body attachable fitting part and on the other hand to first and second furniture part-side pivot axes are pivotally mounted on the holding part.

It is possible that three additional connecting joints are arranged on the two support arms, so that a total sieve joint arrangement is formed. However, it is also alternatively a four-bar arrangement used.

In the Siebengelenk arrangement, the support arms may each be designed as toggle lever, each having between the body and flap side pivot axes of the connecting joints, wherein a Tragarmteil one of the knee lever is extended beyond the associated toggle joint out and is articulated on the other knee joint over the other joint connection.

In a further development of the invention, a self-tightening device is provided with at least one power drive for introducing a force in the closing direction and after exceeding a dead center to initiate a force in the opening direction of the folding furniture element.

One of the power drives may comprise a lever gear having a plurality of mutually hinged and mutually pivotable lever arms, which are coupled for movement with the hinge assembly.

The invention further comprises a piece of furniture having the features of independent claim 15.

The FIGS. 1 to 4 The design and function of the furniture fitting 11 will be explained below purely by way of example with reference to a so-called flap fitting, which is intended to drive a furniture flap 13 of a piece of furniture 10, and on the one hand on a furniture body 12 and on the other hand on the furniture flap 13 is to be mounted. Instead of a movable furniture part is therefore spoken of a furniture flap 13 below. It is of course possible to use the furniture fitting 11 for driving a furniture cover, for example, a furniture chest, a door, such as refrigerator door, or a drawer.

According to the first exemplary embodiment, the furniture fitting 11 is thus arranged on a piece of furniture 10, preferably a cabinet, in particular an overhead cabinet, which is fixed in height to a building wall in a suspended manner. The furniture body 12 of the cabinet has mutually opposed vertical side walls 14, of which in the drawing only one is visible, a bottom wall 15, a top wall 16 and a rear wall and includes a limited of these walls furniture compartment 17 with furniture compartment opening 18, wherein the furniture compartment 17th if necessary by a Specialist board (not shown) may be divided in height.

The front of the furniture compartment 17 is associated with the furniture flap 13, which occupies a vertical position in its closed position and the furniture compartment 18 closes. The furniture flap 13 can be adjusted from this closed position after covering a certain opening angle in an access to the furniture compartment permitting open position.

The movable guide the furniture flap 13 between the closed and the open position takes over the furniture fitting 11th

The furniture fitting 11 has a first support arm 19 and a second support arm 20, each pivotable about a first and second body side pivot axes 21, 22 pivotally attached to a furniture body 12 fitting part 23 and on the other hand to first and second flap-side pivot axes 24, 25 pivotally connected to a the furniture flap 13 attached holding part 26 are mounted.

The two support arms 19, 20 are each designed as a toggle lever and each have a body-side and a flap-side support arm part 27a, 27b; 28a, 28b. The Tragarmteile 27a, 27b of the first support arm 19 and the Tragarmteile 28a, 28b of the second support arm 20 are each connected via a connecting joint 29, 30 pivotally connected to each other.

As in particular in FIG. 1 shown, the body side support arm 27a is formed by a profile element with a U-shaped cross-section. This profile element has a bottom wall 35 with an opening 36 and two substantially perpendicular from the bottom wall 35 upwardly projecting and profile legs 31a, 31b arranged parallel to one another. The flap-side support arm 27b is configured in a similar manner, so also has a bottom wall 32 with an opening 33 and two substantially perpendicular from the bottom wall 32 upstanding profile legs 34a, 34b which are arranged parallel to each other. The profile legs 34a, 34b of the flap-side Tragarmteils 27b are guided within the profile legs 31a, 31b of the body side Tragarmteils 27a, wherein a connection via the connecting joint 29 takes place, which in turn has a connecting pin 37 which is fitted over openings of the nested profile elements.

The body-side support arm part 28a of the second support arm 20, which is mainly used for control, is expediently designed as a flat band which dips between the two profile legs 31a, 31b of the body-side support arm part 27a of the first support arm. The body-side mounting of this support arm part 28a can take place, for example, by a substantially circular bend of the flat band around a bearing pin forming the body-side pivot axis 21.

The flap-side support arm part 28b of the second support arm 20 is, as mentioned, connected via a connecting joint 30 to the body-side support arm part 28a. Conveniently, the flap-side support arm 28b also consists of a profile element with a U-shaped cross-section. Again, a configuration with a bottom wall 38 and two of this substantially perpendicular upstanding profile legs 39a, 39b expedient. The flap-side support arm part 28b of the second support arm 20 is extended beyond the connection joint 30 and is connected via a further connecting joint 40 pivotally connected to the body-side support arm part 27a of the first support arm 19. This emerges as a profile element designed flap-side support arm 28b of the second support arm 20 between the two profile legs 31a, 31b of the body side support arm 27a of the first support arm part. Further, the flap-side end of the flap-side Tragarmteils 28b of the second support arm 20 surrounds the holding part 26 and is pivotally mounted there on the second flap-side pivot axis. By interlocking designed as profile elements Tragarmteile the two support arms 19, 20 results in a very compact design of the furniture fitting 11 in the folded state, as exemplified in FIG. 2 shown.

According to the first embodiment, the arrangement of the first body-side pivot axis 21 of the first support arm 19 and the second body side pivot axis 22 of the second support arm is selected such that the body-side pivot axis of the second support arm 20 is disposed in close proximity to the furniture compartment opening 18, while the body-side pivot axis 21 of first support arm 19 in the direction of the furniture compartment opening 18 to the furniture compartment 17 behind the body-side pivot axis 22 of the second support arm 20 sits. Furthermore, the body-side pivot axis 21 of the first support arm 19 is arranged below the body-side pivot axis 22 of the second support arm 20. In the flap-side pivot axes 24, 25 of the two support arms 19, 20, an arrangement is selected such that the flap-side pivot axis 25 of the second support arm 20 is arranged closer to a lower edge of the furniture flap 13 than the flap-side pivot axis 24 of the first support arm 19. The first support arm 19th So this is in total longer than the second support arm 20. This is especially true for the length of the body side support arm 27a, 28a, wherein the body side support arm 27a of the first support arm 19 is significantly longer than the body side support arm 28a of the second arm 20 is formed. The holding part 26, on which the two flap-side pivot axes 24, 25 of the two support arms 19, 20 are arranged, has a fastening means in the form of screws attached to the back of the furniture flap 13 lower part 41. Further, a aufgeklipstes on the lower part 41 upper part 42nd provided, on which the two flap-side pivot axes 24, 25 are located. The position of the flap-side pivot axes 24, 25 can be adjusted with an adjusting device 43, whereby an adjustment in the X-, Y- and Z-direction of an X, Y and Z coordinates spanned Cartesian coordinate system is possible.

As in particular in FIG. 1 shown, the adjusting device 43 formed on the upper part, extending in the X and Y directions slots 44, 45 which are penetrated by mounted in the lower part 41 adjusting means. As adjusting screws 46, 47 are provided, of which in each case one in the associated slot 44, 45 sits. There are also provided height adjustment means, with which the distance from the upper and lower part 41, 42 of the holding member 26 can be adjusted to each other. As a height adjustment means is a further adjustment screw 48, which passes through a screw opening on the upper part 42 and screwed into the lower part or can be screwed. By means of this adjusting device 43, the furniture flap 13 can thus be aligned exactly with the furniture carcass 12, so that in the closed position a precise fit of the furniture flap 13 to the furniture compartment 17 is made possible.

FIG. 2 shows the closed position of the furniture flap 13. In this closed position, the two support arms 19, 20 are folded, the second support arm 20 is almost completely immersed within the profile legs 31a, 31b of the first support arm 19. When opening the furniture flap 13, for example in an in FIG. 3 shown intermediate position, pivots the body-side support arm 27a about the body-side pivot axis 21 to the outside, wherein both the first connecting joint 29 and the further connecting joint 40 pivot about this first body-side pivot axis 21. In this case, the first connection joint 29 already comes out of the furniture compartment 17 after a relatively short pivoting movement. When opening the furniture flap 13, the first support arm 19 folds out, whereby the distance between the body-side pivot axis 21 and the flap-side pivot axis 24 increases.

The second support arm 20 pivots to the outside about the second body side pivot axis 22. In this case, the second connecting joint 30 pivots about this body-side pivot axis 22 circular outwards and also pivots out of the furniture compartment 17 after certain pivoting. The second support arm also works when opening the furniture flap 13, wherein the distance between the body-side pivot axis 22 and the flap-side pivot axis 25 increases.

In FIG. 4 the situation is shown in the open position of the furniture flap 13. In the open position, both the first and the second connection joint 29, 30 are completely pivoted out of the furniture compartment 17, so are in front of the furniture compartment opening 18 and at the same time these joints 29, 30 are below the furniture flap 13. The two connecting joints 29, 30 support the Furniture flap 13 so in its open position in the rear, the furniture body 12 facing area. The further connecting joint 40 can also pivot at least partially out of the furniture compartment opening 18. Second connecting joint 30 and further connecting joint 40 are arranged relatively close to each other, so that here is a further supporting effect of the furniture flap 13 results. By such Siebengelenk arrangement thus a support or support of the furniture flap is achieved in the case of a designed as a furniture flap movable furniture part. Furthermore, the lateral stability is increased. In particular, in large and heavy furniture flaps 13 thereby sagging the furniture flap, especially in the middle of the valve, prevented.

The furniture fitting 11 also has a Selbstanzugeinrichtung 49 with a first power drive 50 for initiating a closing force in the closing direction and after exceeding a dead center to initiate an opening force in the opening direction on the furniture flap 13. The first power drive is integrated into the multi-joint arrangement of the furniture fitting 11 by it is effectively interposed between two of the relatively pivotable articulated arms of the multi-joint arrangement. The multi-joint arrangement is shown by way of example as Siebengelenk arrangement according to the first embodiment. However, it is also possible to use the first power drive 50 in a designed as a four-joint furniture fitting 11. However, the function of the self-tightening device 49 will be explained below by way of example with reference to the integration into a sieve joint arrangement.

As in particular in the FIGS. 1 and 3 illustrated, the first power drive 50 is seated on one of the support arms 19, 20 and acts in terms of forces with an abutment 41 which sits on a relative to the two support arms 19, 20 pivotable component. Expediently, the first power drive 50 is arranged on the flap-side support arm part 27b of the first support arm, while the abutment 51 is located on the holding part 26. For this purpose, the upper part 42 of the holding part 26 is fork-shaped extended beyond the adjusting device 43 and has two fork legs 52a, 52b, between which the bearing block like designed abutment 51 sits and protrudes down from the fork opening. The abutment 51 further has a stop element, which may be configured, for example, as a cylindrical stop 53.

The first power drive has a pressure piece 54 which is pivotally mounted about a pressure piece pivot axis 55 on the flap-side support arm 27b of the first support arm 19. The pressure piece 54 has at least one spring element in the form of a compression spring 56, a thrust piece 57 in abutment against the abutment 51 presses. As in particular in FIG. 4 shown, the compression spring may be guided in a pressure piece housing 58, and on the one hand supported on the bottom of the pressure piece housing 58 and on the other hand supported on a particular annular abutment surface of the thrust piece 57. The thrust piece 57 in turn is also cylindrical and has a cylindrical bearing portion 59 which is disposed within the compression spring and a stopper portion 60 which is extended by means of the compression spring 56 from the pressure piece housing 58. The free end of the abutment portion 60 has a concave contour, resulting in a reliable contact with the cylindrical stop pin 53 of the abutment 51.

As in particular in FIG. 2 shown in the closed position of the furniture flap 13, the force acting direction of the thrust piece 57 along the line between the pressure piece pivot axis 55 and a force introduction point, which is formed by the vertical through an active surface of the abutment 51. As in FIG. 2 shown, this force application point is on the line between the pressure piece pivot axis 55 and a central axis of the cylindrical stop pin 53. The stop pin 53 is located at a distance a from the bearing point of the abutment on the holding part 26. In the in FIG. 2 illustrated closed position of the furniture flap 13 is the direction of action of the thrust piece 57 such that a pivoting moment in the clockwise direction is exerted on the holding part 26 and thus on the furniture flap 13 as a result of the lever arm a, whereby a closing force in the closing direction 13 acts on the furniture flap. The furniture flap 13 is therefore held with closing force in its closed position.

When opening the furniture flap 13, this closing force must be overcome, up to the in FIG. 3 shown intermediate position corresponding to the dead center. In this dead center, the pressure piece pivot axis, the force application point and the bearing point of the abutment, which essentially corresponds to the flap-side pivot axis 24 of the first support arm 19, are in line. Thus, no moment is exerted on the furniture flap 13 by the thrust piece 57.

If the furniture flap 13 then opened further and finally enters the in FIG. 4 illustrated open position, the force action direction moves to the other side of the bearing point of the abutment 51, whereby a force in the counterclockwise direction, ie in the opening direction is exerted on the furniture flap 13 as a result of the lever arm a.

The self-tightening device 49 may be designed such that when closing the furniture flap from the in FIG. 4 shown open position after exceeding the dead center FIG. 3 an independent closing or retracting into the closed position ( FIG. 2 ) takes place, without the user would have to intervene supportive here. When opening the flap, it is possible that the Selbstanzugeinrichtung 49 is designed such that after exceeding the in FIG. 3 shown Totpunktslage an independent opening up to the in FIG. 4 shown open position is possible. The Selbstanzugeinrichtung 49, however, may alternatively be designed such that the furniture flap 13 after exceeding the in FIG. 3 shown dead center position in the opening direction remains in any position. An advantage of such a self-tightening device 49 is that integration into the hinge arrangement of the furniture fitting is possible. The furniture fitting 11 can therefore be folded up including the self-tightening device 49 to a compact Einfaltlage, as exemplified in FIG. 2 is shown. In this case, the self-tightening device 49 is received between the profile legs 34a, 34b of the flap-side support arm part 27b of the first support arm 19.

According to the first embodiment, the furniture fitting 11 still another, second power drive 61, which is arranged on the fitting part 23, which in turn is attached to the side wall of the furniture body 12. However, this second power drive 61, which provides in conjunction with a lever mechanism 68 for supporting the self-tightening, is not absolutely necessary, especially not for relatively small and lightweight furniture flaps. However, if relatively large and heavy furniture flaps 13 are used, it is advantageous to use another power drive. However, it is possible for the second power drive 61 to be only one-sided, i. on one of the two furniture fittings that sit on the left and right of the side wall of the furniture compartment 17 to install.

The second power drive 61 has the form of a spring accumulator. The spring accumulator has a base element 62, which is fastened about a bearing axis 63 pivotably on the body-side fitting part 23. On the base member 62, a lock slider 64 is held axially adjustable along an adjustment axis 65. The lock slider 64 is by means of compression springs 66, on the one hand against the base member 62 and on the other hand against the Support adjusting slide 64, acted upon in the direction of an extended position with force. Thus, the compression springs 66 do not bend transversely to the adjustment axis 65, a mandrel 67 is provided on the lock slider 64 per compression spring 66, which dive in the turns of the coil springs designed as compression springs 66 and protect the respective compression spring 66 against lateral bulging.

The second power drive 61 is connected via a lifting gear 68 with the seven-bar arrangement. The lifting gear 68 comprises a rocker-like force deflection lever 69, which is pivotally mounted via a body-side rocker pivot axis 70. The reversing lever pivot axis 70 divides the power deflection lever 69 into a first lever arm 71a, which is assigned to the second power drive 61 and a second lever arm 71b facing away from it. At the first lever arm 71a is a coupling member 72 in the form of a coupling bolt, which is engaged by the adjusting slide 64 of the second power drive 61, whereby the force exerted by the power drive 61 force is introduced to the Kraftumlenkhebel 69. The coupling member 72 thus represents the force introduction interface between the second drive 61 and the force deflection lever 69. The coupling member 72 is displaceably mounted on the first lever arm 71a of the force deflection lever 69. Thus, the force introduction interface and therefore the size of the introduced force can be adjusted. For this purpose, the coupling member 72 is connected to a sliding piece 73, which in turn is displaceably mounted in a receptacle 74 in the first lever arm 71a of the power reversing lever 69. The sliding piece 73 can, for example, be penetrated by a guide pin 75, along which the sliding piece 73 can be displaced. By suitable locking means, the desired position of the sliding piece 73 can be fixed.

On the second lever arm 71b of the force reversing lever 69 is a push rod 76 which is pivotally connected via a push rod hinge 77 with the power reversing lever 69. As in particular in FIG. 1 illustrated, the push rod 76 is configured as a profile element, wherein two push rod legs 78a, 78b engage around the second lever arm 71b of the Kraftumlenkhebels 69 and are pivotally mounted by means of the push rod hinge 77 on Kraftumlenkhebel 69. At the end of the push rod 76 facing away from the force deflection lever 69, a second push rod hinge 79 is provided, via which the push rod 76 is pivotally mounted on the seven-bar arrangement. Conveniently, the end of the push rod 76 immersed in the opening 36 of the body side Tragarmteils 27a of the first support arm 19 and is pivotally connected by means of a pivot pin on the two profile legs 31a, 31b of this body side support arm 27a.

As in particular in FIG. 2 shown, the second power drive 61 tries to pivot the power reversing lever 69 in the counterclockwise direction. Decisive for whether a force in the closing direction or a force in the opening direction is ultimately exerted on the furniture flap 13, the position of the connecting line between the two push rod joints 77, 79 and the body side pivot axis 21 of the first arm 19. In the in FIG. 2 shown position exerts the push rod 76 by the position of the connecting line to the left of the body side pivot axis 21 a moment on the first arm 19 and ultimately on the furniture flap 13 in the clockwise direction, ie in the closing direction, from. When opening the furniture flap 13, this connection line travels over a dead center position in which the two push rod joints 77, 79 and the body-side pivot axis 21 lie together on a line on the other side, whereby a force in the opening direction is exercised, such as in the illustration in FIG. 4 shown.

The furniture fitting 11 also has a damper 80 for damping the flap movement of the furniture flap 13 when retracting into the closed position. The damper 80 is formed as an oil damper. Alternatively, however, could also use an air damper. The damper 80 has a damper housing 81 which is attached to the seven-bar arrangement. In the damper housing 81, a damper piston 82 is slidably guided, wherein the free end of the damper piston 82 forms a stop surface 83 which is arranged with a arranged on the furniture body 12 counter-stop surface 84 cooperates such that upon contact of the stop surface 83 with the counter-stop surface 84 develops a damping effect. Conveniently, the counter-abutment surface 84 is formed on a counter-stop tab 85 which protrudes from the fitting part 23 substantially perpendicular and parallel to the ceiling wall 16 ( FIG. 1 ).

The FIGS. 5 to 10 show a second embodiment of the furniture fitting 11. According to this embodiment, the furniture fitting 11 is intended for mounting on a Faltmöbelelement in the form of a folding flap. In principle, however, it would also be possible to use the furniture fitting 11 on another Faltmöbelelement, for example, folding door o.

The folding flap has an upper flap portion and a lower flap portion 87, which are hinged together on a hinge axis 88. The hinge axis 88 is usually of two each at one of the two lateral end portions formed the furniture flap 13 arranged hinges 89, one of which is exemplified. The hinge 89 has an upper hinge part 90 to be fastened to the upper flap part 86 and a lower hinge part 91 to be fastened to the lower flap part 87, which hinges to each other by means of a hinge pin 92 or the like forming the hinge axis. The two hinge parts 90, 91 may be attached to the furniture compartment 17 facing inside of the flap parts 86, 87. The hinge axis 88 may be located near the joint 93 between the two flap parts 86, 87 or at a certain distance above or below the joint 93. In the present embodiment, the hinge axis 88 is located a little way below the joint 93.

The upper flap portion 86 is connected via a hinge assembly with the furniture body 12. The hinge assembly may be formed by a plurality of hinges, which are fastened on the one hand to the top wall 16 and on the other hand to the inside of the upper flap part 86. To connect the upper flap portion 86 with the furniture body, however, can also be a four-bar arrangement or, as in the FIGS. 5 to 10 exemplified to serve a Siebengelenk arrangement. The seven-bar arrangement corresponds to that of the first embodiment of the FIGS. 1 to 4 ,

The furniture fitting 13 further has a control lever 94 which is pivotally mounted on the one hand about a body-side pivot axis 95 and on the other hand to a flap-side pivot axis 96 pivotally mounted on the lower flap portion 87. The control lever 94 is part of a control device, whose other components will be discussed in more detail below. The flap-side pivot axis 96 of the control lever 94 is disposed on a control lever bearing 97, which in turn is attached to the inside of the lower flap portion 87. The control lever bearing 97 may for example be designed as an angle piece, wherein a bearing portion 98 projects from a base portion 99 substantially at right angles from the inside of the lower flap portion 87. The flap-side pivot axis 96 of the control lever 94 is then in the upper region of the bearing portion 98. It can be formed, for example, by a bearing pin is inserted through mutually aligned openings on the control lever 94 on the one hand and on the bearing portion 98 on the other hand, resulting in a pivotable mounting of the control lever 94 at the bearing section 98 results.

At the other end of the control lever 94, so the furniture body 12 facing, is the body-side pivot axis 95 of the control lever 94, which is not fixedly arranged on the furniture body 12, but is articulated on a steering lever 100, which in turn in the mounted state of the furniture fitting 11 with respect the furniture body 12 by means of a steering lever pivot axis 101 is pivotally mounted. The body-side pivot axis 95 of the control lever 94 is thus arranged relatively movable relative to the furniture body. As in particular in the FIGS. 11 and 12 illustrated, the steering lever 100 may be configured as an angle lever, which has two mutually angle lever legs 102a, 102b. At the free ends of the lever legs 102a, 102b is in each case an attachment interface 103a, 103b, via which the steering lever 100 is pivotally connected on the one hand to the control lever 94 and on the other hand with an articulated arm of the joint arrangement. The lever arm 102a of the steering lever 100 assigned to the control lever 94 can, as in particular in FIG FIG. 12 shown, have a flat shape, wherein the attachment interface 103a projecting at one of this lever leg 102a inwardly Projection 104 is arranged. At this projection 104 is a bearing pin 105 which is slotted in the middle and has two flanks 106a, 106b. The flanks 106a, 106b expand toward their free ends. With this configuration, it is possible to couple a corresponding opening on the control lever without tools with the bearing pin 105 by the opening is pressed over the two flanks, which move as a result of the central slot to each other, whereby the opening snaps over the flanks. The control lever 94 is now freely pivotally mounted on the steering lever 100. At the free end of the other lever arm 102b is a kind of bearing fork 108 is attached, which has two substantially mutually parallel fork legs 109a, 109b. At the front, free end of the two fork legs 109a, 109b is in each case a recess 110a, 110b, which widens from a cross-sectional small insertion opening into an approximately circular bearing opening. On the outer sides of the fork legs 109a, 109b are each a spring-loaded latching lug 111a, 111b, which protrudes from the outside of the respective fork legs 109a, 109b to the outside. The coupling of the steering lever 100 with one of the articulated arms of the joint arrangement is carried out without tools. As an articulated arm here serves the push rod 76 of the lever mechanism. The two recesses 110a, 110b at the free ends of the fork legs 109a, 109b can thereby be snapped onto the bolt which connects the push rod 76 with the force deflection lever 69. As a result, the steering lever pivot axis 101 and the first push rod joint 77 overlap one another. When coupling the steering lever and push rod 76 further snap the two locking lugs 111a, 111b in corresponding latching openings on the outside of the lever tongs push rod legs 78a, 78b of the push rod 76 a. Push rod 76 and steering lever 100 are therefore not movable relative to each other. The steering lever 100 could therefore also be referred to as push rod extension.

As already mentioned, the control lever 94 is part of a control device, to which furthermore an overload clutch 112 belongs. The overload clutch 112 is configured such that it disengages at an occurring due to a blocking of the unfolding movement of the two flap parts 86, 87 overload while canceling the force caused by the control device forced operation.

The overload clutch 112 is, as in the Figures 9 and 10 shown, between two in the disengaged state relatively movable control lever parts 113a, 113b of the control lever 94 is effective. One of the control lever parts 113a has a relatively large length and is pivotally connected on the one hand via the body side pivot axis 95 of the control lever 94 in the manner described above with the steering lever 100. On the steering lever 100 opposite end of this control lever part 113a is a detent opening 114, with this control lever part 113a can be coupled to the other control lever part 113b.

The other control lever part 113b is designed as a kind of coupling piece, on which the other control lever part 113a is held positively and / or non-positively in the coupled state by coupling means belonging to the overload coupling. As in particular in FIG. 13 illustrated, counted to the coupling means a guide housing 115, within which the end of the other control lever part 113a is arranged. The guide housing 115 ensures that the two control lever parts 113a, 113b can not separate from one another transversely to a control lever longitudinal axis. At the bottom of the guide housing 115 is also a spring-mounted locking tongue 116, which is engaged in the coupled state of the overload clutch 112 in the associated detent opening 114 of the other control lever part 113 a. In this state, the two control lever parts 113a, 113b are relatively immovably coupled to each other. At the other end of the control lever part 113b designed as a coupling piece there is a bearing opening 117, via which this control lever part 113b is pivotably connected to the bearing section 98 of the flap bearing 97 in the manner described above.

As in particular in FIG. 6 shown, designed as a folding flap furniture flap 13 is initially in its closed position in which the two flap parts 86, 87 abut the furniture compartment 17 and the furniture compartment opening 18 close. The two flap parts 86, 87 have a mutually coplanar position.

When opening the furniture flap 13, the steering lever 100 provides support for the seizure of the two flap parts 86, 87. When opening, the lower edge of the lower flap portion 87 lifts from the furniture body 12, wherein the lower flap portion 87 at the same time about the hinge axis 88 as indicated by arrow 118 pans inside. The lower flap portion 87 is supported by the control lever 94 so that the pivotal position of the lower flap portion 87 with respect to the upper flap portion 86 is controlled. The body-side pivot axis 95 of the control lever 94 is not fixedly mounted on the furniture body, but connected to the steering lever 100, which in turn is coupled to the push rod 76 and this in turn to the Siebengelenk arrangement. When the furniture flap 13 is opened, a force acts in the closing direction via the self-tightening device 49, which force has to be overcome in the manner described above up to a dead center position. After exceeding this dead center then acts a force in the opening direction, until the furniture flap 13 then in the in FIG. 8 shown open position arrives. In this open position, the control lever 94 with the plane of the furniture compartment opening 18 forms an obtuse angle, the acquisition of this position is achieved with the cooperation of the steering lever 100. In this position of the control lever 94, access to the furniture compartment 17 is increased relative to the furniture flaps 13 mounted by means of conventional furniture fittings.

As in particular in FIG. 8 is shown, a gap 93 is formed between the two flap parts 86, 87, which has the maximum joint width in the open position. When folding movement of the furniture flap 13, the joint width is always smaller up to the closed position. In order to prevent that when closing the furniture flap caught in the joint fingers of the user are clamped, the overload clutch 112 is provided. In contrast to conventional finger guard hinges, which act directly on the joint, ie on the hinge 89 in such valves, the overload clutch is in the region of the control lever 94, as in the Figures 9 and 10 is shown trained. If the fold-in movement of the furniture flap 13 is thus blocked, for example, by fingers, the overload coupling disengages by the control lever part 113a disengaging with its latching opening 114 from the latching tongue 116 of the other control lever part 113b, whereby the two control lever parts 113a, 113b are moved relative to one another. The positive guidance of the two flap parts 86, 87 is thus canceled and the two control lever parts 113a, 113b perform such a translational movement from each other that the two flap parts 86, 87 while maintaining the joint width of the joint 92 are moved as a kind of rigid arm. Since the joint width is no longer reduced, can also in the joint 93 advised fingers of a user no longer be pinched.
