Definitions
- the invention relates to a folding door hinge and a functional unit, in particular a piece of furniture or a room segment, with a folding door, in particular a folding sliding door, which is provided with at least one folding door hinge.
- folding doors are often used, which are preferably moved into a door compartment or into a parking space after the opening has been released so as not to appear disruptive.
- a functional unit with a folding sliding door is known, for example, from US8336972B2.
- the US9284761B2 discloses a piece of furniture with a displacement device by means of which a mounting profile connected to a folding sliding door can be displaced within a door compartment.
- the folding sliding door comprises two door elements, of which the first door element is connected at the back by stop hinges to a mounting profile and at the front by folding door hinges to the back of a second door element, which is connected at the front to a drive which is displaceable along a running rail, the two aligned perpendicular to each other and has rail sections connected to one another by a curve section, of which a first rail section runs into the door compartment and a second rail section runs along the front of the piece of furniture.
- the mounting profile is held in a vertical orientation by a support device and is provided on the top and bottom with guide tracks that are slidably mounted in guide rails.
- the folding door is extended from the door compartment and unfolded. In the closed position, the door elements are aligned planar to one another. To open the piece of furniture, the folding door is folded again, with the door elements being inserted into the door compartment in an open position, preferably aligned parallel to one another.
- the DE202018100262U1 discloses a holding device that can be actuated by pressure and which supports both the holding of the folding door in the closed position and the folding process after the folding door has been released from the closed position.
- This device comprises a first fitting part which is connected to the first door element of the folding door and a second fitting part which is connected to the second door element of the folding door. Between the first fitting part and a coupling device arranged on the second fitting part there is an ejection element which is movably connected to the first fitting part and the coupling device.
- the first fitting part is adjusted relative to the coupling device via an energy storage device which is to be loaded manually by the user and which acts against the ejection element.
- a triggering device is connected to the second door leaf via a connecting cable.
- the locking device is unlocked by applying pressure to the planar-aligned door elements, whereby they are further pushed out of the planar alignment in the closing direction.
- This device has a complex structure and requires numerous device parts, of which a first group has to be connected to the first door element and a second group has to be connected to the second door element. Furthermore, device parts are provided which connect the two fitting parts and thus the two door elements with one another and of which first device parts are mechanically guided with appropriate effort and second device parts are held loosely, which is generally not desirable.
- the door elements of the folding door are also held in the closed position solely by the holding device, which is why measures are required to counteract accidental unlocking. Due to the use of two fitting parts, care must also be taken to ensure that they are connected to the first and second door elements at the correct distance from one another and in the correct mutual orientation and height. It should also be noted that this device takes up a lot of space, which is disadvantageous given the limited space within the piece of furniture and especially within a door compartment.
- US3846868A discloses a folding door hinge provided with a spring, by means of which hinged door elements are rotated either into the open position or into the closed position after a central position has been exceeded.
- the folding door hinge has a complex design and requires fitting elements that must be mounted on the upper edges of the door elements.
- DE3104275A1 discloses a drive spring
- Folding door hinges by means of which hinged door elements can be automatically rotated against each other. Shown are folding door hinges with hinge levers that are connected to each other by spiral springs or leaf springs, for which a corresponding amount of space is required. When opening and/or closing the folding door hinge, the spiral spring is stretched, whereby no advantageous force curve can be achieved. In particular, hinges equipped with a drive spring in this way only develop the desired rotational force over a very small rotation range.
- spiral springs with high spring constants are more difficult to install. If the spiral spring with a high spring constant is pre-assembled, it is very difficult to assemble the folding door hinge on two door elements of the foldable door. However, subsequent installation of the spring with a high spring constant at the installation site is hardly possible or only possible with the appropriate tools.
- the KR102137007B1 discloses a folding door hinge with two drive springs, each held in a pot and penetrated by a hinge shaft which has a reduced diameter in the area of the springs. This folding door hinge requires more effort to produce. The effect of the two springs, each of which only has a few turns, is limited.
- US721A discloses a folding door hinge with a first and a second plate-shaped hinge lever and with a drive spring which has two spring assemblies which are connected to one another by a spring center piece and which each have a spring end piece on the sides facing away from one another. The spring end pieces rest on the first hinge lever and the spring center piece rests on the second hinge lever. After assembling this folding door hinge, it is ready for use. As described above, installing the ready-to-use folding door hinge on the door elements of a folding door is difficult. Installing the folding door hinge is particularly difficult if a particularly powerful drive spring is used. The present invention is therefore based on the object of creating an improved folding door hinge that is equipped with a drive spring. Furthermore, a functional unit, in particular a piece of furniture, is to be created with a folding door that is equipped with at least one such folding door hinge.
- Folding door hinges according to the invention should be easy to mount on the door elements of a folding door.
- the folding door hinge which has two hinge levers connected to each other by a drive spring, should only take up a small amount of space, so that hardly any additional space is required compared to conventional hinges.
- the folding door hinge should therefore hardly appear visually and should be able to be optimally integrated into a door system.
- the drive spring should be able to transmit high forces to the hinge levers.
- high forces should be able to be transmitted over a high rotation range of the hinge levers.
- the folding door hinge equipped with the drive spring should be of simple construction and its construction should preferably differ only slightly from conventional hinges, which have two hinge levers connected to one another by a hinge axis. In particular, no or only very simple structural device parts should be required to accommodate the drive spring.
- the folding door hinge should preferably work without friction, so that no noise is caused and no signs of wear occur even after long periods of operation.
- the maintenance effort should be reduced to a minimum.
- the use of the drive spring should, if possible, not impair the freedom of design of the other parts of the hinge, so that the folding door hinge equipped with the drive spring can continue to be designed as desired and is hardly limited to structural features that affect the design of the other hinge parts could.
- the drive spring should be easy to assemble and connect to the hinge levers.
- a drive spring with a very high spring constant should also be able to be mounted in a simple manner.
- the drive spring should be able to be installed without the use of tools.
- the drive spring should be able to be mounted, preferably automatically, with minimal manual effort.
- a foldable door which is held in a closed position by means of a holding device and is released from the closed position by manual action, should preferably be able to be folded automatically and completely.
- a door gap between the door elements of the foldable door, which are connected to one another by hinges, should preferably be able to be covered with a cover that is correctly aligned after the door elements have been folded and prevents manual intervention between the door elements and also provides privacy protection , which gives the partially or fully folded folding door an aesthetically advantageous appearance.
- the folding door hinge includes a first hinge lever, which has a first lever end piece with at least one bearing opening and a second lever end piece, which is connected or connectable to a first mounting part; a second hinge lever, which has a first lever end piece with at least one bearing opening and a second lever end piece which is connected or connectable to a second mounting part; a hinge axle, which is held in the bearing openings of the hinge levers and connects the two hinge levers to one another in an articulated manner; and a drive spring, which rests on the first hinge lever on the one hand and on the second hinge lever on the other hand.
- the first lever end piece of the first hinge lever includes two first and second inner bearing arms which are spaced apart from one another and provided with associated bearing openings and between which the first end piece of the second bearing arm is held. Furthermore, the first lever end piece of the first hinge lever comprises two first and second outer bearing arms spaced apart from the inner bearing arms.
- the drive spring comprises two spring assemblies which enclose the hinge axis and which are connected to one another by a spring center piece which rests on the second hinge lever.
- the first spring package which is arranged between the first inner bearing arm and the first outer bearing arm, comprises, at an end facing away from the spring center piece, a first spring end piece which rests on the first outer bearing arm.
- the second spring package which is arranged between the second inner bearing arm and the second outer bearing arm, comprises, at an end facing away from the spring center piece, a second spring end piece which rests on the second outer bearing arm.
- the first hinge lever has a holding element for each of the spring end pieces, into which the associated spring end piece is or can be hung, or that the second hinge lever has a holding part into which the spring center piece is or can be hung, or that the first hinge lever has a holding element for each of the spring end pieces, into which the associated spring end pieces can be hung, and that the second hinge lever has a holding part into which the spring middle piece is or can be hung.
- the folding door hinge according to the invention which is provided with a drive spring, can therefore be easily mounted on the door elements of a folding door or sliding folding door.
- the drive spring activated and hung with the spring end pieces in the holding elements and/or the spring center piece in the holding part.
- the holding elements are designed as latching elements into which the spring end pieces can snap, or that the holding part is designed as latching elements into which the spring center piece can snap, or that the holding elements are designed as latching elements into which the spring end pieces can snap, and that the holding part is designed as a locking element into which the spring center piece can lock.
- the spring end pieces can advantageously be connected to the holding elements and/or the spring center piece can advantageously be connected to the holding part. It is described below that the activation of the drive spring can advantageously also be carried out by actuating the folding door in a preferred embodiment.
- the invention it is therefore possible to advantageously integrate a strong drive spring with two spring assemblies into the folding door hinge without any difficulties occurring during assembly.
- the two spring assemblies are able to exert high forces on the hinge levers, so that the folding door folds automatically after being released from a closed position.
- the spring assemblies of the drive spring preferably have helical or thread-shaped windings that rest against one another or are at least partially spaced from one another from turn to turn, so that the spring assemblies are axially compressible.
- the drive spring Due to the screw-shaped design of the drive spring, it can exert a high spring force on the hinge levers within a large rotation range of around 180°.
- the drive spring can also be provided with a preload if desired.
- the helical design of the drive spring allows a practically coaxial alignment of the spring assemblies with respect to the hinge axis and thus the axis of rotation of the hinge, which is why only little space is required. Even if the coils of the spring packs are provided with a larger diameter, the result is still a very slim structure of the folding door hinge.
- the compressibility of the spring assemblies makes it easier to connect them to the first hinge lever.
- the Spring end pieces are moved axially and can be automatically guided more easily over a holding element that is provided on the first and second outer bearing arms using a tool or when the folding door hinge is operated. A blockage can therefore be avoided.
- the drive spring coupled to the second hinge lever can be easily coupled to the first hinge lever by rotating the second hinge lever relative to the first hinge lever. A tool for coupling the drive spring to the hinge levers can therefore be dispensed with.
- the first and second outer bearing arms each preferably comprise a holding element which has a ramp or an inclined flank which preferably faces the second hinge lever and via which the associated first or second spring end piece can be inserted into a holding channel located behind the holding element. in which the associated first or second spring end piece is held after the folding door hinge has been put into operation.
- the drive spring can therefore be coupled to the first hinge lever in a simple manner by rotating the second hinge lever with the drive spring against the first hinge lever.
- the spring end pieces lying at the height of the holding elements hit the ramp of the holding elements and are guided along this over the holding elements until they can fall into a holding channel behind the holding elements.
- This process can be easily completed by mounting the hinges on the door elements and then folding the door elements until the spring end pieces are guided over the holding elements and lock into the associated holding channel.
- the spring center piece is preferably held on the second hinge lever by a holding element when the second hinge lever is rotated away from the first hinge lever and the drive spring is tensioned.
- the holding element is hook-shaped or nose-shaped, so that the spring center piece is reliably held.
- the spring center piece is held on the second hinge lever between the holding element and a driver which holds the spring center piece when the second hinge lever is rotated against the first hinge lever and the spring end pieces are coupled to the holding elements. Between the holding element and the driver is thus a locking depression is formed in which the spring center piece is always securely held regardless of the direction of rotation of the second hinge lever.
- the hinge axis is held friction-free in the bearing openings of the hinge levers, preferably by means of bearing elements made of plastic, for example a slippery thermoplastic such as POM.
- bearing elements preferably fulfill additional functions.
- To secure the hinge axis against axial displacement it is preferably held pressed in one of the hinge arms. However, the axial displacement of the hinge axis can also be prevented by means of at least one locking ring.
- a bearing roller is held within the spring assemblies of the drive spring by the hinge axis, the outside diameter of which is at least smaller than the inside diameter of the spring assemblies.
- the bearing rollers preferably have an axial bore whose inside diameter corresponds approximately to the outside diameter of the hinge axis.
- the bearing rollers are therefore preferably held rotatably by the hinge axis with little play and are able to follow the movements of the spring assemblies and keep them in axial alignment. However, if the bearing rollers are held firmly, they still keep the spring assemblies in the correct alignment due to their ability to slide.
- the spring assemblies are therefore always optimally aligned and cannot deform or jam. The movements of the spring assemblies occur friction-free or largely friction-free without causing noise and/or signs of wear.
- the bearing openings of the first and second outer bearing arms preferably have an inner diameter that allows one of the bearing rollers to be pushed through and into the associated spring assembly. In this way, the folding door hinge can be easily assembled.
- the bearing openings of the first and second outer bearing arms have an inner diameter that allows one of the bearing rollers to be pushed through and into the associated spring package and further into a bearing opening part of the facing first or second inner bearing arm.
- the bearing rollers are held on both sides and form bearing elements for the hinge axis.
- the hinge axis can therefore Bearing rollers hold, or the bearing rollers can keep the hinge axis and the spring assemblies optimally supported.
- the hinge axis projects beyond the first hinge lever on one side or on both sides, so that one end piece of the hinge axis or both end pieces of the hinge axis can be connected to a cover device in a simple manner. If no cover is provided, the hinge axis is preferably not extended beyond the hinge levers.
- the panel device preferably comprises a panel profile which has two profile side pieces connected to one another by a profile center piece.
- at least one holding module is held in a form-fitting, movable and lockable manner, which has a connecting element which is firmly or releasably connected to the hinge axis.
- the connecting element is preferably a retaining clip which can be placed on the associated end piece of the hinge axis and which snaps into place.
- the hinge arms of the folding door hinge are preferably designed in such a way that the panel device is held behind the folding door in the closed position of the door elements and on the front side between the door elements after the door elements have been folded.
- the door elements can be guided against each other at the front without leaving an annoying door gap. After opening the folding door, however, it is ensured that the door gap is covered by the cover profile and thus an aesthetically advantageous view protection is achieved and the door gap cannot be intervened manually.
- first lever end piece of the first hinge lever is provided with at least one first stop element
- first lever end piece of the second hinge lever is provided with at least one second stop element.
- the first and second stop elements are arranged on the first and second hinge levers in such a way that they are aligned in opposite directions after the two hinge levers have rotated and form stop surfaces for the cover profile. After opening the folding door, the panel profile is opened using the folding door hinge or The stop elements are therefore always held in a desired orientation in which the door gap is correctly covered.
- a functional unit according to the invention for example a piece of furniture, such as a cupboard, or a room segment, is provided with at least one folding door with two door elements, which are connected to one another with a folding door hinge according to the invention or with several folding door hinges according to the invention.
- the folding door hinges preferably hold a panel device with a panel profile, by means of which the door gap between the door elements is closed when they are folded against each other.
- the folding door can be locked in a closed position by means of a holding device and can be released from the closed position again, after which the folding door can be automatically converted into a folded state by the folding door hinge or hinges.
- the first door element is connected to a mounting profile on an edge remote from the folding door hinges by stop hinges, which is displaceable within a door compartment of the functional unit.
- the second door element is connected to a guide drive on an edge remote from the folding door hinges, which is guided in a guide rail which runs along the front of the functional unit.

- the holding lever 22 is rotated and the holding magnet 28 is aligned almost frontally against the closure element 20, so that it can magnetically couple to the magnetic or ferromagnetic closure element 20 in the closed position of the folding door 11.
- the two door elements 111, 112 are preferably folded automatically. This folding process is carried out automatically or at least supported by folding door hinges 3 according to the invention, which connect the two door elements 111, 112 to one another.
- the folding door hinge 3 comprises two hinge levers 31, 32, which are each connected to the associated door element 111, 112 at the ends facing away from one another by mounting parts, preferably hinge cups 39 and which are connected to one another at the mutually facing lever end pieces by a hinge axis 33. Furthermore, a drive spring 34 is provided, which acts with spring end pieces on the first hinge lever 31 and with a spring center piece on the second hinge lever 32, as described below. The drive spring 34 thus acts on the two hinge levers 31, 32 and tries to rotate them against each other and to fold the door elements 111, 112.
- Fig. 2 also shows a spacer plate 200, which does not fulfill any function in the closed position of the folding door 11.
- the front piece of the holding lever 22 with the spacer rollers 29 rests against the spacer plate 200 and is pressed against the mounting part 21 and preferably aligned parallel to it, so that it is pushed into the door compartment 10 takes up as little space as possible (see Fig. 4).
- Fig. 3 shows part of the folding door 11 of Fig. 2 shortly before reaching the closed position or shortly after being released from the closed position.
- the door elements 111, 112 of the folding door 11 are not yet aligned in one plane and the holding magnet 28 is not yet in contact with the closure element 20.
- the holding lever 22 is inclined relative to the mounting part 21 and faces the closure element 20 and is connected to it with the spacer rollers 29 contact first.
- the spacer rollers 29, which are preferably made of plastic, will hardly cause any noise.
- the holding magnet 28 is sunk into a magnetic chamber and is partially enclosed by a magnetic cup and projects beyond the front, for example by 0.2 mm - 2 mm, so that the holding magnet 28 cannot strike the closure element 20.
- the holding device 2 comprises a locking unit 24 with a force transmitter 241, which in the locking unit 24 is cyclically moved by the action of pressure between a locking position in which the holding device 2 reaches a holding position and a release position in which the holding device 2 reaches a holding position
- the locking unit 24 with the force transmitter 241 is shown schematically.
- the force transmitter 241 supported by an adjusting spring 243, is axially displaceable and actuates a switching mechanism 242, in which a locking element is cyclically moved between a locking position and a release position.
- the folding door hinge 3 includes a drive spring 34, which is tensioned in this position of the folding door 11 and tries to fold the door elements 111, 112 against each other against the force of the user.
- the holding device 2 must therefore be magnetically coupled to the closure element 20 in the closed position and locked by means of the locking unit 24 so that the folding door 11 is held in the closed position.
- the drive spring 34 is therefore loaded by manual force and subsequently serves to automatically fold the folding door 11 as soon as it is released from the closed position.
- Fig. 4 shows the folding door 11 of Fig. 3 with the first door element 111 in a sectional view and the second door element 112 in a parallel orientation, in which the folding door 11 can be inserted into the associated door compartment 10.
- the front piece of the holding lever 22 rests on the spacer plate 200 with the spacer rollers 229 and holds the holding lever 22 at least approximately parallel to the mounting part 21.
- Fig. 5a shows the folding door hinge 3 of Fig. 2, which includes a first hinge lever 31 and a second hinge lever 32, which are connected to one another by a hinge axis 33. Furthermore, the folding door hinge 3 includes a drive spring 34 with two spring assemblies 341, 342, which are connected to one another by a spring center piece 343 and on which spring end pieces 3411, 3421 are provided.
- the drive spring 34 is tensioned in this position of the hinge 3 and encloses the hinge axis 33 with the spring assemblies 341, 342. Furthermore, the drive spring 34 lies with the spring end pieces 3411, 3421 on the first hinge lever 31 and with the spring center piece 343 on the second hinge lever 32 at.
- the first hinge lever 31 includes a first lever end piece 311 with four bearing arms 3111, 3112, 3113, 3114 (see Fig. 5b), two outer bearing arms 3111, 3114 and two inner bearing arms 3112, 3113, which from the hinge axis 33 are pierced, and a second lever end piece 312, which is connected to an associated mounting element or hinge cup 39.
- the second hinge lever 32 comprises a first lever end piece 321, which is held between the two inner bearing arms 3112, 3113 of the first hinge lever 31 and pierced by the bearing shaft 33, and a second lever end piece 322, which is connected to an associated mounting element or hinge pot 39.
- Holding elements 314 are provided on the outer bearing arms 3111, 3114, in which the spring end pieces 3411, 3421 of the spring assemblies 341, 342 are suspended and held.
- the second bearing arm 32 has a holding part 324 in which the spring center piece 343 is held suspended.
- the spring assemblies 341, 342 try to move the first hinge lever 31, which is held by the spring end pieces 3411, 3421, in a clockwise direction and around the hinge axis 33 and the second hinge lever 32, into which the spring center piece 343 is suspended, in a counterclockwise direction around the hinge axis an axis of rotation x defined to rotate.
- the diameter of the bearing rollers 35 is preferably selected such that there is always play between the bearing rollers 35 and the spring assemblies 341, 342, even if their inner diameter changes when the folding door hinge 3 is actuated.
- Mounting elements for example hinge cups 39, can be connected in any way in a non-positive and/or positive manner to the facing lever end pieces 312, 322. As shown, the mounting elements 39 are preferably displaceable or adjustable relative to the lever end pieces 312, 322 and can be fixed at a suitable location.
- Fig. 5b shows an exploded view of the folding door hinge 3 from Fig. 5a in a preferred embodiment. It is shown that in this embodiment the inner bearing arms 3112 and 3113 have smaller bearing openings 31120, 31130, which only cover the hinge axis 33, but not the Bearing rollers 35 can accommodate.
- the bearing rollers 35 each have an axial bore 350, in which the hinge axis 33 is preferably held rotatably but largely free of play.
- the outer bearing arms 3111 and 3114 however, have larger bearing openings 31110, 31140 into which the bearing rollers 35 can be inserted.
- the first end piece 321 of the second hinge lever 32 is also provided with a bearing opening 3210 into which the hinge axis 33 is already inserted.
- the folding door hinge 3 can therefore be easily assembled by inserting the first lever end piece 321 of the second hinge lever 32 between the two inner bearing arms 3112, 3113 of the first hinge lever 31 and the spring assemblies 341, 342 of the drive spring 34 each between an outer and an inner bearing arm 3111, 3112 or 3114, 3113 can be inserted.
- the bearing rollers 35 are then inserted through the bearing openings 31110, 31140 of the outer bearing arms 3111, 3114 and into the associated spring assembly 341 or 342.
- the hinge axis 33 is guided through the lever end pieces 311, 321, the bearing rollers 35 and the spring assemblies 341, 342.
- the spring center piece 343 is connected to the holding element 324 of the second hinge lever 32.
- the spring end pieces 3411, 3421 must be hung in the holding elements 314 on the outer bearing arms 3111, 3114.
- the hinge levers 31, 32 are connected to mounting elements 39.
- the folding door hinge 3 is in the configuration of FIG. 5a, in which the spring end pieces 3411, 3421 are suspended in the holding elements 314 on the outer bearing arms 3111, 3114.
- the holding elements 314 are cuboid, which is why the spring end pieces 3411, 3421 have to be raised over the holding elements 314 with a tool.
- this process is significantly simplified by a preferred embodiment of the holding elements 314, so that the coupling process can be carried out practically automatically.
- the drive spring 34 takes up hardly any space and still develops a very high spring force, so that the door elements 111, 112 move from the closed position, in which they are aligned in one plane, preferably to the folded position which they are aligned parallel to each other, can be rotated powerfully. In the area of the folded position, the force exerted by the drive spring 34 is reduced to a minimum. In addition, the movement of the door elements 111, 112 in this area are preferably damped by means of a damping element or a damping device so that no impact noises occur.
- the spring assemblies 341, 342 supported by the bearing rollers 35 remain aligned coaxially with the hinge axis 33 during this rotation process and can work without friction. It is particularly advantageous that the spring assemblies 341, 342 do not have to be arranged and held within a hinge housing, but can be arranged virtually exposed, which results in a simple structure with minimal space requirements. The drive spring 34 is therefore almost completely integrated into the folding door hinge 3, which results in an optimal solution visually and functionally.
- the drive spring 34 can follow the movements of the hinge arms 31, 32 without friction with the two spring assemblies 341, 342, which exert high forces on the hinge arms 31, 32. It is particularly advantageous that a powerful drive spring 34 can be integrated into the folding door hinge 3 without taking up significantly more space.
- FIG. 6a shows the folding door hinge 3 of FIG. 2 in a preferred embodiment with the drive spring 34 of FIG Hinge lever 31 are coupled.
- the folding door hinge 3 in which the drive spring 34 is not yet coupled to the first hinge lever 31, the folding door hinge 3 only has a hinge function, but not a drive function. In this state, the folding door hinge 3 can therefore be easily mounted on the door elements 111, 112.
- the spring end piece 3411 is still in front of the ramp 3141, which is designed to be stepless, so that the spring end piece 3411 can slide over it when rotating. With another one Rotation of the drive spring 34, the spring end pieces 3411, 3421 are guided over the ramp or the inclined flank 3141 until they have overcome the holding elements 314 and can each enter a holding channel 3140 in which they are held firmly.
- the windings of the spring assemblies 341, 342 are preferably spaced apart from one another, so that the spring assemblies 341, 342 can be compressed during the process of coupling the spring end pieces 3411, 3421 and the spring end pieces 3411, 3421 can thereby more easily overcome the ramps 3141 of the holding elements 314.
- the hinge lever 32 can carry the spring center piece 343 during a clockwise rotation
- the hinge lever 32 is preferably provided with a driver 325, which is opposite the holding part 324.
- the spring center piece 343 is therefore held in a locking recess 328 (see FIG. 9) between the holding part 324 and the preferably provided driver 325.
- Fig. 6a also shows a diaphragm device 4 with a diaphragm profile 41, in which a holding module 42 is held in a form-fitting but axially displaceable and fixable manner.
- a holding module 42 To fix the holding modules 42, they have a threaded hole 420 into which a threaded bolt can be screwed up to the cover profile 41 and clamped with it.
- the holding modules 42 For connection to the folding door hinge 3, the holding modules 42 have a connecting element, preferably in the form of a retaining clip 423, which can be coupled to the hinge axis 33, which projects beyond the first hinge lever 31 on both sides and is therefore led out of the folding door hinge 3 on both sides.
- the panel device 4 can therefore be easily connected to the folding door 11 or Hinges 3 can be coupled to the folding doors in order to cover or close the opening between the two door elements 111, 112 when they are folded against each other. On the one hand, this covers the aesthetically disturbing gap in the door. On the other hand, it prevents manual intervention in the door gap and prevents injuries from occurring when operating the folding door.
- Fig. 6a further shows an optional function of the two hinge levers 31, 32, which control the aperture device 4 or to hold the panel profile 41 in a desired orientation within the open door gap between the first and second door elements 111, 112.
- the first lever end piece 311 of the first hinge lever 31 facing the hinge axis 33 has a first stop element 316 at least on one of the outer lever arms 3111, 3114 and the first lever end piece 321 of the second hinge lever 32 facing the hinge axis 33 has a second stop element 326.
- the first stop elements 316 of the first hinge lever 31 and the second stop element 326 of the second hinge lever 32 are guided forward to one side of the cover profile 41, which is thereby automatically parallel to the front of the functional unit 1 is aligned. This ensures that the aperture device 4 or the cover profile 41 can actually perform the intended function and cover the door gap between the folded door elements 111, 112.
- FIGS. 7a, 7b and 7c The process of coupling the spring end pieces 3411, 3421 to the first hinge lever 31 is illustrated in FIGS. 7a, 7b and 7c with a view of the first spring end piece 3411.

- the driver 325 rotates the spring center piece 343 clockwise
- the spring end piece 3411 or The spring end pieces 3411, 3421 were guided onto the ramp 3141 of the associated holding element 314 and, if necessary, slightly bent and/or raised by compression of the spring assembly 341.
- Fig. 7b has the spring end piece 3411 or the spring end pieces 3411, 3421 have overcome the ramp 3141 and have snapped into place behind the holding elements 314.
- Fig. 8a shows a section along line A--A through the folding door hinge 3 of FIG. 7a with the first spring end piece 3411 of the drive spring 34, which is guided when the second hinge lever 32 rotates clockwise over the ramp 3141 of a holding element 314 on the first lever end piece 311 of the first hinge lever 31 until it engages behind the holding element 314 in a holding channel 3140 .
- Fig. 8b shows the first lever end piece 311 of the first hinge lever 31 from FIG. 8a with the holding element 314, which has an inclined flank or ramp 3141, and which is connected to the holding channel 3140, which is delimited on one side by the holding element 314 and on the other side by a preferably provided holding cam 315.
