Description

Flap fitting for a furniture, side wall of a furniture body and

Furniture with a side wall

The invention relates to a flap fitting for a furniture, comprising a lever mechanism with a plurality of levers for guiding a flap of the furniture and a damping unit with at least one damper for damping the flap when approaching a closed end position. In this case, the damping unit is disposed within a housing of the flap fitting and has a stop on which one of the levers of the lever mechanism for damping the movement of the flap rests. Furthermore, the flap fitting comprises a spring unit which acts via a pressure roller on a control section of the lever mechanism and holds the flap fitting in the closed and / or an open end position. The invention further relates to a side wall of a furniture body and a piece of furniture with a side wall.

Furniture, especially kitchen furniture or home furniture such as base cabinets or wall cabinets, generally have a forwardly open furniture body, are mounted on the guided over fittings movable furniture parts. Flaps are often used as movable furniture parts, in particular for wall cabinets for closing the furniture body, which are mounted on at least one, usually two, laterally arranged flap fittings. The flap fittings allow the flap to be opened upwards (pivoting up), the flap being e.g. can be pivotable about a horizontally extending imaginary pivot axis arranged in the upper region of the furniture body. Other upward opening movements of a flap are also conceivable. The lever mechanism of the flap fitting is usually more than one piece

Multi-jointed lever mechanism is formed so that a so-called door bearing lever to which the flap is attached, performs a combined pivoting and sliding movement or a pivoting movement, which takes place about a pivot axis, which is outside the flap fitting and usually outside the furniture body.

A flap fitting of the type mentioned is known from the document CN 204826984 U. In this flap fitting is a linear damper via a lever chain with one of the levers of the lever mechanism, which is a furniture flap leads and carries, coupled. The coupling takes place inter alia via a guide curve, which is designed so that the damper is actuated only when approaching the flap to the closed position and thus becomes active. From a certain opening position of the flap, the damper is not active and thus does not hinder free movement of the flap. However, the lever chain for operating the linear damper complicates the structure of the flap fitting.

It is an object of the present invention to provide a flap fitting of the type mentioned, in which a movement is damped in the closed end position, wherein the damper is integrated with the least possible effort in the flap fitting. In this case, the flap fitting should be as compact as possible be built, so that it can also be integrated into a side wall of a furniture body. It is a further object to provide a side wall for a furniture body with a flap fitting or a piece of furniture with such a side wall with these advantages.

This object is achieved by a flap fitting or a side wall or a piece of furniture with the features of the respective independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.

An inventive flap fitting of the type mentioned is characterized in that the stop of the damping unit is actuated when closing the flap fitting by the control section of the transmission lever of the lever mechanism.

According to the invention, a structurally simple coupling of the damper takes place in that the damper is designed and positioned such that the control section of the transmission lever of the lever mechanism abuts against the closed end position of a flap guided by the flap fitting. The serving as a control portion of the transmission lever can thus additionally actuate the damper unit. The additional functionalities (connection to the spring unit or connection to the damping unit) require that the transmission lever protrudes beyond the hinge points, by which it is coupled with other levers of the lever mechanism. If the protruding part fulfills both additional functionalities at the same time, material or installation space can be saved. The flap fitting can thus be incorporated into a side wall of the furniture body or inserted into a built-in from the front side of the side wall bag in the side wall. Alternatively, it would also be possible to arrange the flap fitting in the side wall so that at least one side wall of the flap fitting or a housing of the flap fitting forms almost a plane with the side wall.

In an advantageous embodiment of the flap fitting, in which the lever mechanism forms a sieve joint, a transmission lever of the lever mechanism, which is connected at three hinge points with further levers of the lever mechanism, the lever with which the damping unit cooperates. This lever of the seven-joint performs a combined sliding and pivoting movement, wherein in particular when approaching the closed end position, the proportion of the pivoting movement is small compared to the proportion of the sliding movement. As a result, a linear damper can advantageously be used in the damping unit and when the transmission lever is in contact, it does not slip or only slightly slips along the stop.

In a further advantageous embodiment of the flap fitting, the damping unit has a receptacle for the damper, wherein the receptacle comprises guide means to guide a carriage on which the stopper is formed. Preferably, the damper is designed as a linear damper with a cylinder and a piston with piston rod. The cylinder can be coupled with the receptacle and the piston rod with the carriage or vice versa, the cylinder with the carriage and the piston rod coupled to the recording. In this way, a commercially available damper can be used, wherein the stop is formed in the appropriate size and shape on the carriage. Any force components acting transversely to the direction of movement of the piston rod (for example, by a pivoting portion of the lever with which the damping unit co-operates) are received by the guide and do not act on the linear damper, which could otherwise cause leaks of the damper.

In a further advantageous embodiment of the flap fitting, the housing has two parallel and spaced by an intermediate frame side plates. The damping unit can be mounted on at least one of the side plates or on the frame. In a preferred embodiment, the damping unit may be integrated in the frame, for example by integrating the receptacle of the damping unit. RAL is formed with the frame. As a result, the structure and installation of the flap fitting are further simplified.

In a further advantageous embodiment of the flap fitting, the side plates of the housing have an inner spacing which is less than 1 6 millimeters (mm) and preferably less than 14 mm. Such a flap fitting can be integrated into a side wall of a furniture body, which typically has a thickness of 15 mm to about 25 mm.

A side wall according to the invention for a furniture body is characterized accordingly by the fact that such a flap fitting is used or integrated. An inventive furniture with a furniture body and a guided flap, characterized by such a furniture body with at least one side wall with inserted or integrated flap fitting. This results in the advantages mentioned in connection with the flap fitting.

The invention will be explained in more detail below with reference to exemplary embodiments with the aid of figures. The figures show:

Flap fitting of a closed position (Figure 9a), an open position (Figure 9b) and a series of intermediate positions (Figures 9c-e); and

10a-d are each a side view of a fourth exemplary embodiment of a flap fitting in a closed position (FIG. 10a), a completely open position (FIG. 10d) and two intermediate positions (FIG. 10b, c) with the flap open Casing.

1 a and 1 b and 2 a and 2 b is a first embodiment of a flap fitting 1 in a closed position (Fig. 1 a, 1 b) and a fully open position (Fig. 2a, 2b) one of the flap fitting 1 guided and not shown here flap. 1 a and 2a show the flap fitting in an isometric view and Figs. 1 b and 2b in a side view.

In the description, terms such as above, below, left, right refer exclusively to the exemplary representation chosen in the respective figures. The terms front and rear are usually related to an opening movement of the guided flap. The front side is a side facing the user. A housing 1 0 of Klappenbeschlagsl is shown in Figs. 1 a, 1 b and Fig. 2a, 2b respectively open on one side, to represent the internal structure of the flap fitting 1 can. In Figs. 3a and 3b, the flap fitting 1 is shown with closed housing in two different closed positions in an isometric view. In all figures, like reference numerals designate like elements. For reasons of clarity, not every element in all Figures is provided with a reference numeral in the figures. The housing 1 0 is in the present case of two side plates 1 1, of which in the figures, only the rear is reproduced formed. The side plates 1 1 are spaced from each other by a partially circumferential frame 1 2 and aligned parallel to each other. Through the side plates 1 1 and the frame 1 2 lead a plurality of rivets 13 (see Fig. 3a, 3b), with which the housing 1 0 and thus the flap fitting 1 is held together. Instead of

Rivets can also be other fasteners such as e.g. Screws are used. The rivets 1 3 lead through widened portions 121 of the frame 1 2. The housing 1 0 can of course be made in other ways, e.g. by a deep-drawing process or a bending process. It is essential for the housing 10 that the forces of the flap fitting 1 can be absorbed. The e.g. Deep-drawn housing 1 0 would also have side walls 1 1, which are aligned parallel to each other. In the illustrated flap fitting 1, all other components are attached to the side plates 11, for example also with rivets or bolts passing through one or both of the side plates 11.

The flap fitting 1 has a lever mechanism 20 with five levers, which are connected to one another or to the housing 10 in seven pivot points. The flap fitting 1 is thus designed as a seven-bar hinge, wherein the flap fitting can alternatively also be designed as a four-bar linkage or as another joint arrangement. The lever mechanism 20 comprises a door bearing lever 21 as the outermost link of the lever mechanism 20, which has an adjustment device 30 with a mounting plate 31 connected is. At this mounting plate 31 which is mounted from the flap fitting 1 to flap. The adjusting device 30, which is shown in more detail in subsequent figures, allows an adjusting movement of the mounting plate 31 and thus the guided flap relative to the door bearing lever 21st The door bearing lever 21 is rotatably connected to the in Fig. 1 a, 1 b upper hinge point with a transmission lever 22. In a lower hinge point in the figures, the door bearing lever 21 is connected to a deflection lever 23. The reversing lever 23 and the transmission lever 22 are in turn articulated to a control lever 24. The transmission lever 22 is connected at its rear end to a support lever 25, wherein the support lever 25 is in turn rotatably mounted on the housing 1 0. This lever mechanism 20 thus results in a seven-link chain.

As can be seen from FIGS. 2a and 2b, the individual levers of the lever mechanism 20 are shaped such that they form an approximately extended arrangement in the open position of the flap. During the opening and closing operation, the outer element of the lever mechanism 20, the door bearing lever 21, performs a combined rotational and translational movement, by which an attached flap is not only pivoted, but rather is moved forward, which it transfers with its edge a body edge can be performed.

The flap fitting 1 further comprises a spring unit 40, which holds the flap spring-loaded both in the closed and fully opened state. In particular, in the fully open state, the spring unit 40 is able to compensate for the weight of the flap, so that it remains in the open position without further locking lever. In principle, intermediate positions can be provided in which also by the weight of the flap on the flap fitting applied torques are compensated so that the flap remains in these positions.

The spring unit 40 comprises a spring assembly 41 with a plurality of compression springs 41 1. An in the figures right side of the spring assembly 41 is adjustably mounted in position on a spindle unit 42. A left side in the figures of the spring assembly 41 acts on a shorter end of an angle-shaped intermediate lever 43, which is designed as a two-sided lever and pivotally mounted on the housing 1 0. At the end of the second, free lever arm of the intermediate lever 43, a pressure roller 431 is mounted, which acts on a control section 221 of the transmission lever 22.

The control portion 221 is dome-shaped at its edge with a rising (left side of the control portion 221 in the figures) and a falling edge (right side of the control portion 221 in the figures). If the pressure roller 431 abuts the trailing edge, pressure of the pressure roller 431 causes the lever mechanism 20 to move toward the closed position. Accordingly, the angemontierte flap is closed or held closed. During the opening movement, a dead center is run through when the pressure roller is just on the top of the control section 221. In the further course of the opening movement, the pressure roller 431 bears against the rising flank of the control cam, wherein the pressure of the pressure roller 431 causes the lever mechanism 20 to move further in the direction of the open position. Accordingly, the opening movement is supported and the flap held in the open position. Depending on the design of the

The control cam can also open the flap automatically within a defined angular range.

By means of the spindle unit 42, the suspension point of the spring assembly 41 can be moved and so the bias of the compression springs 41 1 can be varied to adjust the pressing force of the pressure roller 431 to the weight and size of the flap.

In Fig. 4, a side wall 2 of a furniture body not shown is reproduced, in which a flap according to the application 1, for example, as shown in Figs. 1 a to 3b, is integrated. A furniture body usually has at least two such side walls 2, wherein in both a corresponding according to the application flap fitting 1 is integrated. The two - or possibly further flap fittings 1, which are integrated in partitions of the furniture carcass - carry a flap closing the furniture body to the front.

In a front end face 3 of the side wall 2, an opening 4 is formed, through which the lever mechanism 20 of the flap fitting 1 extends. The flap fitting 1 is either inserted into the side wall 2 through the opening 4 in a receptacle formed behind it or is already integrated into the side wall 2 when it is produced or through a pocket which is introduced from a side face 5 and an opening 4 has on the front side 3, inserted laterally. In all cases, the flap fitting 1 is integrated in the side wall 2, wherein covered at least in the first two cases of the flap fitting on its sides by side surfaces 5 of the side wall 2 and therefore neither from the outside, nor from the inside of the furniture body is visible. It is essential here that the flap fitting 1 and the side wall of the second form a unit and that the side wall 2 with inserted flap fitting has no or almost no thickness difference.

In order to be integrated into the side wall 2 of the furniture body, the thickness of the flap fitting 1, i. the outer distance of the side plates 1 1, severely limited by specifications regarding the wall thickness of the furniture body. In conventional side walls of furniture carcasses with a thickness of 1 6 millimeters (mm), the thickness of the flap fitting 1 is necessarily below 1 6 mm and is preferably less than or equal to 14 mm. Accordingly, the lever mechanism 20 including the adjusting device 30 is formed so that it can be retracted between the two side plates 1 1, which have this distance.

The adjusting device 30 shown permits a lateral adjustment (independent of each other of side and height adjustment) and a tilt adjustment of an attached flap. In addition, the flap with an attached part of the flap fitting can be easily separated from the remaining part of the flap fitting, which simplifies the assembly of the flap on the flap fitting 1 and the furniture body.

Next, a damping unit 50 is provided which acts on the lever mechanism 20 and so the door bearing lever 21 and thus a connected flap when approaching the closed state, also called closed end position, decelerates.

The damping unit 50 has a receptacle 51, which are guided via fastening means 52, in this case rivets, which are comparable to the rivets 1 3 through both side plates 1 1, so that the damping unit 50 between the two side plates 1 1 is arranged and fixed.

The receptacle 51 serves to receive a damper, which in the present case is designed as a linear damper 54. Further 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 51 1 51 51 51 51 51 1 leadership formed 51, which lead a relative to the receptacle 51 linearly displaceable slide 53 on the recording. The slider 53 has at its front, 51 of the take-up side facing away from a stop 531, against which a lever of the lever mechanism 20 moves when the door bearing lever 21 and the flap approaches the closed end position. In the illustrated embodiment, the lever which drives against the stop 531, the transmission lever 22 which is rotatably coupled in three articulation points with other levers of the lever mechanism 20, specifically the door bearing lever 21, the control lever 24 and the support lever 25th

The transmission lever 22 performs when closing the door bearing lever 21 and the tailed flap movement into the housing 10. Accordingly, the damping unit 50 is arranged in a rear upper region of the housing 10, as viewed from the opening of the housing 10. In the illustrated example, the frame 12 has a recess 122 in the corresponding corner to provide sufficient space for the damping unit 50.

In this rear area, the transmission lever 22 has the control section 221, on which the pressure roller 431 of the spring unit 40 acts. With this control section 221, the transmission lever 22 moves against the stop 531.

In principle, other than the transmission lever 22 of the lever unit 20 may be provided for interaction with the damping unit 50 and the stop 531. In the lever mechanism 20 shown in the embodiment, the transmission lever 22 is advantageous because it performs a superimposed pivoting and sliding movement, wherein in particular in the damped portion of the movement, the sliding movement dominates and the pivoting movement is low. This advantageously leads to the contact point of the stop 531 on the control section 221 moving only minimally along the control section 221 in the damped movement section, as a result of which only slight lateral forces act on the slide 53 and thus on the damper or damper piston rod. Large side forces acting on the slider 53, the guide 51 1 between the receptacle 51 and the slider 53 and would have a greater wear and possibly also a noise result and in particular damaging the damper.

As can be seen in FIGS. 2 a and 2 b, the linear damper 54 is extended in an unloaded state of the damping unit 50, as a result of which the slider 53 is also extended to the maximum extent. The linear damper 54 is in the illustrated embodiment with its visible in Figs. 2a and 2b (but not provided with a reference numeral for clarity) Cylin- which is connected to the slider 53, whereas a not visible in the figures piston rod is coupled to the receptacle 51.

The linear damper 54 preferably has an internal spring which extends it when not loaded. Accordingly, a coupling, for example, between the piston rod and the receptacle 51 requires no firm connection - the piston rod can rest with its end against a stop in the receptacle 51. Basically, a reverse arrangement of the linear damper 54 is possible, in which the cylinder is fixed in the receptacle 51 and the piston rod with the slider 53 cooperates. Also, an external spring is conceivable, which is designed to move the linear damper 54 back to the starting position for the next damping process.

In FIGS. 5a and 5b, 6a-d and 7, a second embodiment of a flap fitting is shown, which corresponds to the first embodiment with respect to its basic structure and in particular its lever mechanism 20. The description of the first embodiment is explicitly referenced. In all figures, like reference numerals designate the same or equivalent elements. In the following, in particular the differences between the two embodiments will be explained in more detail.

In FIGS. 5a and 5b, similar to FIGS. 1a and 2a, the flap fitting 1 of the second embodiment with the housing open is shown in an isometric illustration in a closed and an opened end position. In FIGS. 6a and 6b, comparable to FIGS. 1b and 2b, the flap fitting 1 of the second exemplary embodiment is reproduced in the two end positions in a side view. 6c and 6d show a side view of the flap fitting in two intermediate positions of the door bearing lever 21 and a tailed flap.

A difference from the first embodiment is the flap fitting 1 of the second embodiment in the embodiment of the spindle unit 42 of the spring unit 40. As in the first embodiment, the spring assembly 41 is fixed on one side in position displaceable on the housing 1 0 on the spindle unit 42 and acts on his The spindle unit 42 differs in the second embodiment in that the (not visible here spindle) is arranged in a U-shaped guide rail. From the spring assembly 41 acting on the spindle unit 42 compressive forces are in this embodiment not only from the spindle but also from the u-shaped rail.

Another difference lies in the design of the frame 1 2, which has in particular in the region of the rear, opposite the opening portion of the flap fitting 1 reinforcing ribs 1 23. Integrated in the frame 1 2 and as part of the reinforcing rib 1 23 in the upper rear corner is in this embodiment also the receptacle 51 of the damping unit 50. The integral formation of the receptacle 51 in the frame 1 2 simplifies the assembly, since the damping unit 50 is not separately with the housing 1 0, specifically the side plates 1 1 must be connected.

In the illustrated embodiment, the guide means 51 1 are formed in the form of guide webs on the reinforcing rib 1 23. These cooperate with correspondingly shaped guide contours 532 and 533 of the slide 53. This in turn has in its front region the stop 531 against which the transmission lever 22 abuts to dampen a further closing movement. Fig. 6b shows an opening or closing position of the door bearing lever just before the stop of the transmission lever 22 to the stop 531 and Fig. 6c a closed position in which the stop is straight.

7 shows the integration of the receptacle 51 into the frame 1 2 and the construction of the damping unit 50 in an exploded isometric exploded view.

In this figure, it can be seen that the linear damper 54 has a cylinder 541 and a piston with piston rod 542, in which case - unlike the first embodiment - the linear damper 54 is positioned with the cylinder 541 in the receptacle 51, and the piston rod 542 cooperates with the slider 53.

For the flap fitting 1, an opening damping can also be provided. The damping unit for the opening damping is arranged at a different position than the damping unit 50 for the closing damping. For the opening damping, a linear damper can also be used, with a rotation damper is conceivable. The damping unit for the opening damping can be actuated by a lever arm of the intermediate lever 43, for example. In FIGS. 8a-c and 9a-e, a third embodiment of a flap fitting 1 is shown. Also, this third Ausführungsbespiel corresponds in its basic structure and in particular the structure of its lever mechanism 20, the first and thus the second embodiment.

The spring unit 40 and in particular the displaceable guide of the spring assembly 41 are formed as in the second embodiment. The description of the first and second embodiments is hereby explicitly referred to.

Also in the third embodiment, like reference characters designate like or equivalent elements as in the figures previously shown. In the following, in particular the differences of the third compared to the second embodiment will be explained in more detail.

In FIGS. 8a-c, similar to FIGS. 5a and 5b, the flap fitting 1 is shown with the housing 1 0 open in three different isometric views, specifically in a closed end position in FIG. 8a and in two partially opened layers in FIGS 8b and 8c.

In addition to the components of the second embodiment, a further damping unit 60 is provided in the present third embodiment, which causes a damping of the lever mechanism 20 and thus a mounted furniture part when approaching the fully open end position. Like the damping unit 50, the further damping unit 60 is integrated into the frame 12 in the region of a rear and lower reinforcing rib 1 23 in this case. The further damping unit 60 has a receptacle 61 which is inserted into the reinforcing rib 123 or which is formed integrally therewith. The recording takes on a linear damper 64, which is inserted here with a cylinder 641 in the receptacle 61. The receptacle 61 also provides guide means 61 1 available, on which a slider 63 is slidably mounted. The slider 63 cooperates with a piston rod 642 of the linear damper 64. The further damping unit 60 thus has with respect to the linear damper 64 and its receptacle 61 and its interaction with the slider 63 a comparable with the damping unit 50 construction. Further, as part of the further damping unit 60, a two-sided reversing lever 65 is provided, which has on both sides in each case a first or second slider 651, 652. Instead of the Gleistücke 651, 652 and the use of a pressure roller at these two points is conceivable.

The first slider 651 abuts on the slider 63. The second slider 652 terminates in the range of movement of the intermediate lever 43, the spring forces of the spring assembly 41 transmits to the lever assembly 20. As can be seen in the comparison of FIGS. 8 a and 8 b, the second pressure piece 652 is spaced from the intermediate lever 43 in the closed state of the flap fitting 1. As the opening movement of the lever mechanism 20 of the flap fitting 1 progresses, the intermediate lever 43 approaches the second slider 652. Between the position of the lever unit 20 shown in FIG. 8b and FIG. 8c, the intermediate lever 43 then contacts the second slider 652 with a corresponding contact surface 432. Each further opening movement of the lever mechanism 20 is then transmitted via the reversing lever 65 to the slider 63 and thus transmit the further linear damper 64. Accordingly, the further damping unit 60 dampens the opening movement of the lever mechanism 20 when approaching the fully opened end position.

In order to bring the further damping unit 60 back into the starting position shown in Fig. 8a after re-closing the furniture part or the lever mechanism 20, a return spring is present, which is integrated in the example shown in the linear damper 64. In order to obtain a defined starting point for the use of damping, a stop 66 is formed on the housing 1 0, specifically on the frame 1 2 in the region of the reversing lever 65, which defines the starting position of the reversing lever 65 shown in Fig. 8a. By the combination of the damping unit 50 and the further damping unit 60, both a closing damping (by the damping unit 50) and an opening damping (by the further damping unit 60) are achieved independently of each other. By implementing the closing and opening damping by means of different damping units 50, 60, damping parameters and the points of application of the damping can advantageously be selected independently of each other. It is understood that in alternative embodiments, only one opening damping can be implemented by a flap fitting although the further damping unit 60, but not the damping unit 50th In Figs. 9a-e, an opening movement is again shown stepwise in five different positions. 9a and 9e show the completely closed or completely open position and FIGS. 9b-d respectively show intermediate positions with increasing opening angle of the lever mechanism 20 or corresponding to a furniture part carried by the lever mechanism 20.

Another difference from the previous embodiments relates to the spring assemblies 40. In this example, guide rods 41 2 are provided which lead through the outer of the compression springs 41 1 and the movement in compression or relaxation within the spring package 40 lead. In the embodiments shown above, a comparable guide is achieved by guide channels, in the compression springs 41 1 outside surrounded. In Fig. 1 0a-d another embodiment of a flap fitting 1 is shown with integrated damping. The figures are each side views of the flap fitting 1 with the housing cover open in different opening positions of the flap fitting. 1 10a shows the fitting in the closed position with the lever mechanism 20 fully retracted, FIGS. 10b and 10c show two intermediate positions, and FIG. 10d shows the flap fitting 1 with the lever mechanism 20 fully extended. In this embodiment too implemented both a closing loss, as well as an opening loss. The corresponding damping units 50, as well as the further damping unit 60, correspond in their construction to those from the previous exemplary embodiment of FIGS. 8a-c and 9a-e. In the exemplary embodiment of FIG. 10a-e, the force transmission between the transmission lever 22 and the spring unit 40 is different. Instead of the single two-sided intermediate lever 43 which was used in all previous exemplary embodiments, transmission is in this case via one of three individual levers 43a-c existing lever assembly provided.

The lever arrangement comprises two two-sided levers 43a and 43c, which are coupled to each other via a connecting lever 43b. The housing-fixed pivot points of the lever 43a and c are indicated by the reference numeral 433a and 433c in Figs. 1 0-1 0e. Again, one end of the lever assembly is an end here of the first lever 43a connected to the spring assembly 41 and a free end of the lever assembly, here one end of the third lever 43c, carries a pressure roller 433, which acts on a correspondingly shaped control portion 421 of the transmission lever 22.

Comparing with the single lever 43 of the previous embodiments, the lever arrangement of the levers 43a-c leads to a reversal of the direction of movement. Correspondingly, the control section 221 is formed on the lower side of the transmission lever 22 in FIGS. 10a-e, not on the upper side in the figures. By the force of the compression springs 41 1 of the spring assembly 41, the roller 431 is pushed upwards, not down to hold on the one hand the lever mechanism 20 in the closed position, and on the other hand to support the opening movement at larger opening angles. The arrangement shown may be advantageous over the arrangement shown in the first embodiments, when a compact construction of the flap fitting 1 is in the foreground.

The closing damping is achieved as in all exemplary embodiments shown by a direct contact of the free end of the transmission lever 22 with the slider 53 of the damping unit 50. The opening damping is achieved by contact of the contact surface 432 of the first lever 43 a of the lever arrangement with the second pressure piece 652 of the reversing lever 65.
