Description

Technical Field

[0001] This invention relates to a furniture accessory for movably supporting a furniture flap, particularly a two-piece furniture flap, on the furniture body. The invention also relates to furniture comprising the furniture accessory. Background Technology

[0002] The above-mentioned types of furniture accessories are known in the prior art in a variety of different implementations.

[0003] As an example of prior art, reference is made to document AT 413 418 B. This application's... Figure 1a b and Figure 2a Figure 1 shows an embodiment of the invention of AT 413 418 B. Figure 1a b shows the furniture with the flap closed, where... Figure 1b Show Figure 1a Detailed view. Figure 2a b shows the furniture with its flap open, where... Figure 2b Show Figure 2a Detailed view.

[0004] The furniture 1 shown here, with furniture fittings, has a two-piece furniture flap 2, wherein a first flap component 21 is normally arranged on top in the assembled state, and a second flap component 22 is arranged on the bottom in the assembled state. The first flap component 21 and the second flap component 22 are rotatably connected via a flap-flap hinge 7. In addition, the first flap component 21 is rotatably connected to the furniture body 11 of the furniture 1 via a body-flap hinge 9.

[0005] Furniture 1 has at least one furniture accessory, particularly two furniture accessories, said furniture accessory having at least one adjusting arm 3, particularly exactly one adjusting arm. This adjusting arm 3 is rotatably connected to the furniture body 11, particularly to the furniture side wall 12 (from...). Figure 1a b and Figure 2a (Not visible in b).

[0006] Furthermore, the at least one furniture accessory has an adjusting arm-flip hinge 8, wherein the adjusting arm-flip hinge 8 rotatably connects the adjusting arm 3 to the second flip-cover component 22. This connection is located below the flip-flip hinge 7, particularly in the area of ​​the lower edge 23 of the second flip-cover component 22.

[0007] Each hinge here is formed as a hinge with a rotating hinge joint and a rotating axis, wherein all rotating axes are arranged parallel to each other. Therefore, the rotating axes of these four hinges form the four edges of a quadrilateral that deforms when opened and closed. In the closed position ( Figure 1aIn (b), the quadrilateral is stretched out, while in the open position ( Figure 2a In (b), the quadrilateral has a larger area.

[0008] A known drawback of such a furniture flap 2 (also known in many other documents) is the bending in the area of ​​the flap-flap hinge 7 when the furniture flap is in the essentially closed position. Because the quadrilateral formed by the rotating hinge joint is almost stretched out here, the flap-flap hinge may bend in the "wrong" direction, i.e., toward the furniture body 11.

[0009] This is problematic because the opening motion of the furniture flap 2 is blocked when it bends. In order to enable the furniture flap 2 to open, the bend must first be reversed.

[0010] In particular, when the user pulls the lower edge 23 of the second furniture component 22 outward (away from the furniture body 11), the furniture flap 2 bends, as is common in common furniture with one-piece flaps.

[0011] AT 413 418 Part B solves this problem. The rotation axis 71 of the flip-top hinge 7 is arranged in the area of ​​the wall thickness S of the upper flip-top component 21, to which the flip-top hinge 7 has a hinge cup 72. In addition, a support 74 is provided on the hinge arm 73 that connects the first flip-top component 21 and the second flip-top component 22 to each other. The support 74 rests against the first flip-top component 21, and in particular against the hinge cup 72, when the furniture flip-top 2 is closed.

[0012] The stop of the support 72 partially prevents the flip-flip hinge 7 from bending.

[0013] A disadvantage of this prior art is that the position of the support 74 is crucial. When the stop of the support 74 moves slightly inward toward the furniture body 11, the furniture flap 2 is not prevented from bending, and the problems described above still exist. When the stop of the support 74 moves slightly outward from the furniture body 11, the furniture flap 2 is no longer fully closed. Therefore, objects may fall out of the furniture 1, and an aesthetically pleasing and uniform front of the furniture cannot be achieved.

[0014] This fact necessitates precise adjustment of the flip-top hinge 7 and requires high dimensional stability of all involved materials. Therefore, it places high demands on both the design and the assembly workers. Summary of the Invention

[0015] Starting from the prior art, the task of the next invention is to realize a furniture accessory and a piece of furniture having the furniture accessory, which at least partially eliminates or reduces the disadvantages described above.

[0016] In particular, a furniture accessory should be developed for furniture that minimizes the risk of furniture flaps bending.

[0017] This is solved by following the features of the present invention.

[0018] The furniture fitting according to the invention for movably supporting a furniture flap, especially a two-piece furniture flap, on the furniture body includes a base connected to or capable of being connected to the furniture body, an assembly device connected to or capable of being connected to the furniture flap, and at least one adjusting arm, especially exactly one adjusting arm, which is supported or capable of being supported on the base at a first end in a manner that allows it to deflect about a rotation axis.

[0019] According to the present invention, the at least one adjusting arm is connected or can be connected to the assembly device at a second end opposite to the first end via at least one multi-hingle mechanism, wherein the at least one multi-hingle mechanism has at least three hinge joints, preferably exactly four hinge joints, and each hinge joint has a rotation shaft.

[0020] By replacing the single-hinged flap-to-flap hinge (as disclosed in the prior art) with a multi-hinged mechanism having more than one hinge joint, the instantaneous center of motion of the furniture flap, i.e., the projection of the instantaneous virtual axis of rotation, can be selected by the geometry of the multi-hinged mechanism.

[0021] Therefore, when the furniture flap is basically closed, the instantaneous center of the opening motion of the furniture flap in the reference system of the stationary adjusting arm can move further into the furniture body or even to the back of the furniture body.

[0022] As the distance between the (virtual) axis of rotation and the furniture flap increases, the movement of the furniture flap has an increasing (vertical) translational component and a decreasing rotational component. If the distance is large enough, it will kinematically prevent or at least reduce the bending of the furniture flap, which corresponds to rotational motion.

[0023] Since bending is prevented using purely kinematic methods, precise adjustment of the base stop is not required.

[0024] In one embodiment, the rotation axes of the at least three hinge joints are specified to be oriented parallel to each other.

[0025] It can be specified that the at least one multi-hinged mechanism has at least two connecting transmission elements, preferably exactly two, wherein the at least one adjusting arm is hingedly connected to the assembly device via the at least two connecting transmission elements. By selecting the arrangement of the at least two connecting transmission elements, the kinematics of the furniture flap, especially the trajectory of its instantaneous center of motion, can be adjusted.

[0026] Consider the at least one multi-hinged mechanism having a first connecting transmission element and a second connecting transmission element, wherein: - The first hinge joint connects the at least one adjusting arm to the first connecting transmission element, and / or - The second hinge connects the at least one adjusting arm to the second connecting transmission element, and / or - The third hinge joint connects the assembly to the first connecting transmission element, and / or - The fourth hinge connects the assembly device to the second connecting transmission element.

[0027] Therefore, the at least one adjusting arm is connected to the assembly device, for example, via a four-hinged mechanism.

[0028] It can be stipulated that furniture accessories are formed so that: - In the first position, particularly the extended position, of the at least one multi-hinged mechanism, the instantaneous center of motion of the assembly device is located outside the at least one multi-hinged mechanism in the reference system of the stationary adjusting arm, particularly inside the furniture body, preferably in the rear two-thirds of the furniture body, especially preferably in the rear one-third of the furniture body, or behind the furniture body, and / or in the assembled state of the at least one furniture accessory. - In the second position of the at least one multi-hinged mechanism, especially in the folded position, the instantaneous center of motion of the assembly device is located in the region of the at least one multi-hinged mechanism in the reference system of the stationary adjusting arm.

[0029] The instantaneous center corresponds to the projection of the virtual axis of rotation. The virtual axis of rotation can be formed by the intersection of two planes that extend through the axis of rotation of the first and third hinge joints and the axis of rotation of rotation that extend through the second and fourth hinge joints.

[0030] Since the instantaneous center is located outside the at least one multi-hinged mechanism in the first position of the furniture fitting, preferably in an extended position (the furniture fitting preferably occupies this first position in the substantially closed position of the furniture flap), especially far inside the furniture body or behind the furniture body, the furniture flap is less prone to bending.

[0031] Since the instantaneous center is located in the region of the at least one multi-hinged mechanism in the second position of the furniture fitting, preferably in the folded position (the furniture fitting preferably occupies the second position in the substantially open position of the furniture flap), the multi-hinged mechanism behaves similarly to a single-hinged hinge in the substantially open position of the furniture flap.

[0032] The at least one assembly device may have an assembly plane on which a furniture flap can be assembled. This assembly plane corresponds to the inner plane of the furniture flap in the assembled state.

[0033] It can be specified that the instantaneous center of motion of the assembly device is arranged on the first side of the assembly plane in the reference system of the stationary adjusting arm, wherein the at least one adjusting arm and / or the at least one multi-hinged mechanism is also arranged on the first side of the assembly plane. Preferably, this is the case in the first position, preferably the extended position, and in the second position, preferably the folded position, and especially in all positions of the at least one multi-hinged mechanism.

[0034] In one embodiment, the at least one adjusting arm includes a connecting member, wherein the at least one multi-hinged mechanism is connected to the at least one adjusting arm via the connecting member. Therefore, the multi-hinged mechanism, together with the connecting member, can be mounted on and removed from the adjusting arm.

[0035] It can be specified that the at least one adjusting arm is detachably connected to the base. For this purpose, a base connecting component is preferably provided, which can connect to the guide sleeve of the at least one adjusting arm and can lock with the base. Therefore, the at least one adjusting arm can be easily connected to the base, which may have already been pre-assembled onto the furniture body.

[0036] It can be specified that the at least one multi-hinged mechanism includes at least two connecting transmission elements, wherein each of the at least two connecting transmission elements includes at least one lever, preferably exactly two levers, and in particular, the at least one lever has at least two holes. Therefore, a connecting transmission element may, for example, include two levers.

[0037] In one embodiment, it is specified that: - The first hinge joint of the at least one multi-hinged mechanism is formed as a hole in the connecting member, a hole in the at least one lever of the first connecting transmission element, and a bolt, and / or - The second hinge joint of the at least one multi-hinged mechanism is formed as a hole in the connecting member, a hole in the at least one lever of the second connecting transmission element, and a bolt, and / or - The third hinge joint of the at least one multi-hinged mechanism is formed as a hole in the assembly device, a hole in the at least one lever of the first connecting transmission element, and a bolt, and / or - The fourth hinge of the at least one multi-hinged mechanism is formed as a hole in the assembly device, a hole in the at least one lever of the second connecting transmission element, and a bolt.

[0038] In one embodiment, the at least one adjusting arm has a connecting member, and the at least one multi-hinged mechanism has at least two connecting transmission elements, wherein the at least two connecting transmission elements include at least two levers, preferably exactly two levers, wherein the connecting member and / or assembly device are arranged between the two levers of the at least two connecting transmission elements, preferably arranged along the direction of the rotation axis between the two levers of the at least two connecting transmission elements. Therefore, a stable multi-hinged mechanism can be achieved.

[0039] It can be specified that the at least one adjusting arm is length-adjustable, wherein preferably: - The length of the at least one adjusting arm is fixable, in particular by means of a locking function and / or by means of a friction element, in particular by means of a spring element that applies pressure to the friction element and / or by means of a locking part, in particular by means of at least one screw, and / or - The length of the at least one adjusting arm is variable during the opening and / or closing movement of the furniture flap, and / or - The at least one adjusting arm has a guide sleeve and a piston, wherein the piston is movable within the guide sleeve, and / or - The at least one adjusting arm has a connecting member, wherein the connecting member is movable relative to the rest of the at least one adjusting arm.

[0040] On the one hand, the length adjustability can be utilized when assembling and adjusting furniture accessories so that the at least one adjusting arm can be adapted to the size of the furniture, especially the furniture flap.

[0041] The length of at least one adjusting arm can be locked during operation.

[0042] However, it is also possible to consider adjusting the length of the arm so that it can be stretched and adjusted during the opening and / or closing movements.

[0043] The at least one adjusting arm can be subjected to torque, wherein an electric drive unit and / or a mechanical energy storage device are preferably provided in the base for this purpose. This simplifies the operation of the furniture flap.

[0044] It can be specified that the torque is related to the adjustment angle of the at least one adjusting arm. Therefore, for example, the torque can always be selected such that it compensates for the weight of the furniture lid. This allows the furniture lid to be held in any position.

[0045] Furthermore, the electric drive unit can be controlled via wireless or wired connection.

[0046] A type of furniture is provided, comprising a furniture body, at least one furniture flap (especially a two-piece furniture flap), and at least one furniture accessory according to the invention, wherein the at least one assembly device is mounted on the at least one furniture flap, and the at least one base is connected to the furniture body, and the at least one adjusting arm is connected to the at least one assembly device by means of the at least one multi-hinged mechanism.

[0047] Therefore, the furniture flap can be held in place by at least one adjusting arm, wherein the dynamics of the furniture flap can be adjusted according to the dimensions of the multi-hinged mechanism. In particular, the dynamics can be selected in such a way that bending is prevented when the furniture flap is substantially closed.

[0048] In one embodiment, the at least one furniture flap includes a first flap component and a second flap component. Preferably, the first flap component is arranged on top in the assembled state, and preferably, the second flap component is arranged on the bottom in the assembled state. The first flap component is hinged to the furniture body and the first flap component is hinged to the second flap component.

[0049] The resulting folding flap has the advantage of using less space above furniture.

[0050] It can be specified that the at least one assembly device is assembled on the second flip-cover component, wherein the at least one adjusting arm is connected to the second flip-cover component by means of the at least one multi-hinged mechanism, preferably connected to the second flip-cover component when the first flip-cover component is omitted.

[0051] One embodiment is characterized by: - In the substantially closed position of the at least one furniture flap, the at least one adjusting arm is substantially parallel to the first flap component and to the second flap component, and / or - In the substantially open position of the at least one furniture flap, the at least one adjusting arm is at an angle of 45° to 135° to the second flap component.

[0052] Furniture can be shaped to make: - In the substantially closed position of the at least one furniture flap, the instantaneous center of the opening movement of the second flap component is located inside the furniture body, preferably in the rear two-thirds of the furniture body, particularly preferably in the rear one-third of the furniture body, or behind the furniture body, especially outside the at least one multi-hinged mechanism, and / or - In the substantially open position of the furniture flap, the instantaneous center of the closing movement of the second flap component is located in the region of the at least one multi-hinged mechanism in the reference system of the stationary adjusting arm.

[0053] Therefore, multi-hinged mechanisms behave similarly to single-hinged hinges in the essentially open position of a furniture flap.

[0054] In the essentially closed position of the furniture flap, the virtual axis of rotation (or instantaneous center) of the flap is located outside the multi-hinged mechanism, thus giving the flap's movement a large translational component. This prevents the flap from bending. Detailed Implementation

[0055] Other details and advantages of the present invention will be described in more detail below with reference to the accompanying drawings. Wherein: Figure 1a Figures a and b show furniture with a closed flap and furniture fittings according to the prior art, a. side view, b. detailed view of the flap-flap hinge joint; Figure 2a Figures a and b show furniture with an openable furniture flap and furniture fittings according to the prior art, a. side view, b. detailed view of the flap-flip hinge joint; Figure 3 A schematic diagram showing an adjustment arm acting on a furniture flap using a single hinge according to the prior art; Figure 4 A schematic diagram showing the adjustment arm acting on a furniture flap by means of a multi-hinged mechanism according to an embodiment of the present invention is shown; Figure 5 A cross-sectional view of furniture with furniture accessories is shown; Figure 6 Furniture accessories are shown separately; Figure 7a -d indicates different positions of the multi-hinged mechanism: a. the extended position when the furniture lid is closed, b and c. the folded middle position, and d. the folded position when the furniture lid is open. Figure 8a Figures a and b show side views of the furniture fittings in the extended position (a) and the folded position (b). Figure 9a b shows a perspective view of the furniture fittings in the folded position; Figure 10 An exploded view of the furniture accessories is shown.

[0056] Figure 1a b and Figure 2a The existing technology in section b has already been discussed above at the beginning of the specification.

[0057] Figure 3 A schematic diagram of a piece of furniture with a hinged cover 2 is shown. The hinged cover has a first hinged cover component 21 and a second hinged cover component 22, wherein an adjusting arm 3 acts on the hinged cover 2 in a manner commonly used in the prior art.

[0058] The adjusting arm 3 is rotatably connected to the furniture body 11 via an adjusting arm hinge joint 51 in the base 5 (not shown here). Only the axis of rotation of the hinge is shown here (in the projection). The axis of rotation of the single-hinged adjusting arm-flip hinge 8 is shown at the opposite end of the adjusting arm 3. The adjusting arm 3 is rotatably connected to the second flip-top component 22 via the adjusting arm-flip hinge 8.

[0059] In a reference system where the adjusting arm 3 is stationary, the movement of the second flip-top component 22, for example, when the furniture flip-top 2 is opened or closed, is limited to rotation about the rotation axis of the adjusting arm-flip-top hinge 8.

[0060] The rotation axis is arranged at a distance X from the second flip-cover component 22. Since the rotation axis is not located in the second flip-cover component 22, the movement of the second flip-cover component 11 in the reference system where the adjusting arm 3 is stationary does not correspond to a simple rotational motion, but also includes a translational component. The larger the distance X, the larger the translational component is relative to the rotational component. (For X approaching infinity, the movement of the second flip-cover component 22 corresponds to a translational motion where the rotational component disappears.)

[0061] The translational component of the movement of the second flap component 22 results in a substantially vertical movement of the second flap component 22 when the furniture flap 2 is substantially closed.

[0062] The bending of the second flip member 22 in the region of the flip-flip hinge 7 corresponds to the rotational movement of the second flip member 22.

[0063] If the rotation axis of the second flap component 22 moves further into the furniture body 11, that is, the distance X increases, the tendency of the second flap component 22 to bend in the area of ​​the flap-flip hinge 7 also decreases.

[0064] Distance X is based on Figure 3 The existing technology in the construction cannot be arbitrarily enlarged.

[0065] The distance X can be, for example, up to 40 mm or up to 50 mm.

[0066] That is, the increase in distance X inevitably leads to a further separation between the adjusting arm-flip hinge 8 and the second flip component 22. Therefore, the adjusting arm 3 is also positioned further inside the furniture body 11. This reduces the space within the furniture body 11 and may cause the adjusting arm-flip hinge 8 and / or the adjusting arm 3 to collide with partitions or other objects within the furniture body 11.

[0067] Figure 4 A schematic diagram of one embodiment of furniture 1 according to the present invention is shown. Here, a multi-hinged mechanism 6 replaces the single-hinged adjusting arm-flip hinge 8.

[0068] Multi-articulated mechanism 6 Figure 4 The embodiment has four hinge joints.

[0069] The multi-hinged mechanism has a virtual axis of rotation that is not typically coincident with one of the axes of rotation of the (four) hinges. Depending on the position of the multi-hinged mechanism 6, the virtual axis of rotation is arranged in different positions and "migrates" along a trajectory given by the geometry of the multi-hinged mechanism 6 as the hinges move.

[0070] The virtual axis of rotation projected onto a plane perpendicular to the axis of rotation is called the instantaneous center of motion.

[0071] exist Figure 4 In the reference system where the adjusting arm 3 is stationary, the instantaneous center of motion of the second flip-top component 22 is positioned at a distance Y from the second flip-top component 22 when the furniture flip-top is closed.

[0072] The geometric design of the instantaneous center 66 is achieved by the intersection of two imaginary straight lines, which extend through the rotating shaft of the hinge joint connecting the transmission elements 61 and 62.

[0073] As by Figure 4 It is evident that the distance Y can be altered by the geometry of the multi-hinged mechanism 6. In particular, it should be mentioned here that the instantaneous center 66 is located further inside the furniture body 11 than the hinge mechanism 6 itself.

[0074] That is, the distances Y and the distances between the multi-hinged mechanism 6 and the second flip-top component 22 can be designed to be at least partially independent of each other. This possible solution... Figure 3 This is not given in the existing technology.

[0075] The distance Y can be, for example, greater than 80 cm or greater than 70 cm.

[0076] The distance Y can be so large that the instantaneous center 66 is located within the rear two-thirds of the furniture body 11 or in the rear one-third of the furniture body. The instantaneous center 66 can also be located behind the furniture body 11.

[0077] The large distance Y results in a larger translational component relative to the rotational component of the movement of the second flip-top component 22 within the reference system where the adjusting arm 3 is stationary. Therefore, the tendency to bend is reduced through the kinematic design of the multi-hinged mechanism.

[0078] Figure 5 A cross-sectional view of a furniture 1 having a furniture body 11, a two-piece furniture flap 2, and furniture fittings 10 is shown, wherein an assembly device 4 is mounted on at least one furniture flap 2, a base 5 is connected to the furniture body 11, and an adjusting arm 3 is connected to the at least one assembly device 4 by means of a multi-hinged mechanism 6.

[0079] The furniture body 11 includes a top 13 and a bottom 14. The furniture sidewalls 12 are also shown, on which the base 5 is fitted.

[0080] Typically, two furniture fittings 19 are assembled to provide movable support for the furniture flap 3, as is the case in the prior art.

[0081] The furniture flap 2 includes a first flap component 21 arranged on top in the assembled state and a second flap component 22 arranged on the bottom in the assembled state, wherein the first flap component 21 is hinged to the furniture body 11, and the first flap component 21 and the second flap component 22 are hinged to each other.

[0082] The assembly device 4 of the furniture accessory 10 is assembled on the second flip-top component 22, wherein the adjusting arm 3 is connected to the second flip-top component 22 by means of the multi-hinged mechanism 6 without the first flip-top component 21.

[0083] In the substantially open position of the at least one furniture flap 2, the adjusting arm 3 is at an angle of 45° to 135° to the second flap component 22.

[0084] In the substantially closed position of the at least one furniture flap 2, the adjusting arm 3 is substantially parallel to the first flap component 21 and the second flap component 22. This is in Figure 5 Not shown in the image.

[0085] Figure 6 Show separately Figure 5 Furniture fitting 10. Furniture fitting for movably supporting furniture flap 2, especially two-piece furniture flap, on furniture body 11 includes a body 5 connected to or capable of being connected to furniture body 11, an assembly device 4 connected to or capable of being connected to furniture flap 2, and an adjusting arm 3, which is supported or capable of being supported on the base 5 at a first end in a manner that allows it to deflect about a rotation axis.

[0086] The adjusting arm 3 is connected to or can be connected to the assembly device 4 at its second end opposite to the first end via at least one multi-hingle mechanism 6, wherein the at least one multi-hingle mechanism 6 has four hinge joints 611, 612, 621, and 622, each hinge joint having a rotation shaft.

[0087] The adjusting arm 3 has a guide sleeve 32 and a piston 33, wherein the piston 33 is movable within the guide sleeve 32. Therefore, the adjusting arm 3 is configured to be of adjustable length.

[0088] The length of the adjusting arm 3 can be achieved via a locking function and / or via a friction element 35, particularly in conjunction with a spring element 34 that applies pressure to the friction element 35 (see [link]). Figure 10 (and / or secured by a locking mechanism, especially by means of at least one screw.)

[0089] The length of the adjusting arm 3 can be dynamically changed during the opening and / or closing movements of the furniture flap 2. In this way, the adjusting arm 3 can, for example, meet the forced conditions imposed by the kinematics of the components including the furniture fitting 10 and the furniture 1.

[0090] The adjusting arm 3 can be subjected to torque, wherein for this purpose an electric drive unit and / or a mechanical energy storage device are preferably provided in the base 5.

[0091] The rotation axes of the four hinge joints are oriented parallel to each other.

[0092] Figure 7a -d indicates the multi-hinged mechanism 6 in different positions.

[0093] The adjusting arm 3 includes a connecting member 31, wherein the multi-hinged mechanism 6 is connected to the at least one adjusting arm 3 via the connecting member 31. The connecting member 31 can be configured to move relative to the rest of the adjusting arm 3. Therefore, the adjusting arm 3 is length-adjustable.

[0094] The multi-hinged mechanism 6 has at least two connecting transmission elements 61 and 62, wherein the at least one adjusting arm 3 is hingedly connected to the assembly device 4 by means of the at least two connecting transmission elements 61 and 62.

[0095] The multi-hinged mechanism 6 has a first connecting transmission element 61 and a second connecting transmission element 62, wherein: - The first hinge joint 611 connects the adjusting arm 3 to the first connecting transmission element 61, and - The second hinge joint 612 connects the adjusting arm 3 to the second connecting transmission element 62, and - The third hinge joint 621 connects the assembly device 4 to the first connecting transmission element 61, and - The fourth hinge joint 622 connects the assembly device 4 to the second connecting transmission element 62.

[0096] The intersection of two imaginary straight lines, one extending through the first hinge joint 611 and the third hinge joint 621 and perpendicular to these two hinge joints, and the other extending through the second hinge joint 612 and the fourth hinge joint 622 and perpendicular to these two hinge joints, corresponds to the position of the instantaneous center 66 of the movement of the second flip-top component 22 and the assembly device 4 in the reference system where the adjusting arm 3 is stationary.

[0097] exist Figure 7aThe multi-hinged mechanism 6 is shown in the "extended" position. This position is occupied by the multi-hinged mechanism 7 in the substantially closed position of the furniture flap 2.

[0098] The instantaneous center is located outside the multi-articulated mechanism 6.

[0099] Therefore, avoid the furniture flap 2 bending when the furniture flap 2 is basically closed.

[0100] In the assembled state, the instantaneous center is located inside the furniture body 11, preferably in the rear two-thirds of the furniture body 11, particularly preferably in the rear one-third of the furniture body 11, or behind the furniture body 11.

[0101] exist Figure 7b Figure c shows the multi-hinged mechanism 6 in its intermediate position. When the furniture flap 2 is substantially open, the multi-hinged mechanism 6 occupies... Figure 7d The location shown in the image.

[0102] exist Figure 7b In -d, the instantaneous center is located in the region of the multi-hinged mechanism 6, especially in the region of the second connecting transmission element 62.

[0103] Therefore, the multi-hinged mechanism 6 behaves similarly to a single-hinged hinge in the intermediate position and in the position where the furniture flap 2 is always substantially open.

[0104] exist Figure 7a In all positions of -d, the instantaneous center of motion of the second flip-top component 22 and the assembly device 4 is arranged on the first side of the assembly plane of the second flip-top component 22 in the reference system of the stationary adjusting arm 3, wherein the at least one adjusting arm 3 and the at least one multi-hinged mechanism 6 are also arranged on the first side of the assembly plane.

[0105] Figure 8a b shows furniture accessory 10 without a base 5. Figure 8a The diagram shows the multi-hinged mechanism 6 in the "extended" position, and... Figure 8b The multi-hinged mechanism 6 is shown in the folded position.

[0106] Figure 9a b shows furniture fitting 10 in a folded position without base 5, in two different perspective views.

[0107] Figure 10 An exploded view of furniture accessory 10 is shown.

[0108] The multi-hinged mechanism 6 includes two connecting transmission elements 61 and 62, wherein each of the two connecting transmission elements 61 and 62 includes two levers 63, and each lever 63 has two holes 64.

[0110] The second hinge joint 612 of the multi-hinged mechanism 6 is formed as a hole 64 in the connecting member 31, a hole 64 in the two levers 63 of the second connecting transmission element 62, and a bolt 65.

[0111] The third hinge joint 613 of the multi-hinged mechanism 6 is formed as a hole 64 in the assembly device 4, a hole 64 in the two levers 63 of the first connecting transmission element 61, and a bolt 65.

[0112] The fourth hinge joint 614 of the multi-hinged mechanism 6 is formed as a hole 64 in the assembly device 4, a hole 64 in the two levers 63 of the second connecting transmission element 62, and a bolt 65.

[0113] The connecting component 31 and the assembly device 4 are arranged between the two levers 63 of the two connecting transmission elements 61 and 62, preferably arranged along the direction of the rotation axis between the two levers 63 of the two connecting transmission elements 61 and 62.

[0114] Therefore, the multi-hinged mechanism 6 is constructed in an interlaced and stable manner.

[0115] The friction element 35, which fixes the guide sleeve 32 of the adjusting arm 3 and the piston 33 to each other, is also clearly visible here. This fixation can be achieved by combining a spring element 34 that applies pressure to the friction element 35.

[0116] The adjusting arm 3 is detachably connected to the base 5. For this purpose, a base connecting component 36 is provided, which can connect to the guide sleeve 32 of the adjusting arm 3 and lock with the base 5. Therefore, the adjusting arm 6 can be easily connected to the base 5, even if the base 5 has already been pre-assembled onto the furniture.
