Definitions

  • the invention relates to a folding door hinge and a functional unit, in particular a piece of furniture, with a folding door, in particular a folding sliding door, which is provided with at least one folding door hinge.
  • folding doors or folding doors are often used, which, after the opening has been released, are preferably moved into a door compartment or into a parking space in order not to disturb to appear.
  • 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 with guide tracks on the top and bottom, which are guided by 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 folding door In the closed position, the folding door must be kept in a planar orientation so that a folding process is not triggered automatically. After opening the folding door from the closed position, it would be desirable if the folding process were carried out automatically.
  • 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 is out of the closed position has been released.
  • 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 when there is usually limited space within the piece of furniture and in particular within a door compartment.
  • a folding door hinge provided with a spring is also known, by means of which door elements which are articulated to one another 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.
  • the DE3104275A1 discloses further folding door hinges provided with a drive spring, by means of which door elements are articulated to one another can be rotated against each other automatically. Shown are folding door hinges with hinge levers that are connected to each other by spiral springs or leaf springs, which require a corresponding amount of space. When opening and/or closing the folding door hinge, the spiral spring is stretched, with no advantageous force progression being possible. In particular, hinges equipped with a drive spring in this way only develop a desired rotational force over a very small rotation range.
  • coil 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 present invention is therefore based on the object of creating an improved folding door hinge which is equipped with a drive spring. Furthermore, a functional unit, in particular a piece of furniture, is to be created with a folding door which is equipped with at least one such folding door hinge.
  • 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, meaning that there is hardly any additional space required compared to conventional hinges.
  • the folding door hinge should therefore have little visual impact and should be able to be optimally integrated into a door system.
  • the drive spring within the hinge 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 as simple as possible and its construction should preferably only differ insignificantly from conventional hinges, which have two hinge levers connected to one another by a hinge axis.
  • 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 use.
  • 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 in any way and is hardly limited to structural features that could affect the design of the other hinge parts.
  • 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 assembled without the use of tools.
  • the drive spring should be able to be mounted with minimal manual effort, preferably almost automatically.
  • a foldable door which is held in a closed position by means of a holding device and released from the closed position by manual action, should preferably be able to be folded completely.
  • Folding door hinges according to the invention should be easily connectable to the folding door of a functional unit and activated in a simple manner.
  • a door gap between the door elements of the foldable door, which are connected to one another by hinges, should preferably 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 a privacy screen, which partially or fully folded folding door gives an aesthetically advantageous design.
  • the folding door hinge includes a first hinge lever having a first lever end piece with at least one bearing opening and a second lever end piece connected or connectable to a first mounting part; a second hinge lever having a first lever end with at least one bearing opening and a second lever end 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 has two spaced-apart first and second inner bearing arms with associated bearing openings, between which the first end piece of the second bearing arm is held, and two first and second outer bearing arms spaced apart from the inner bearing arms
  • the drive spring has two spring assemblies penetrated by the hinge axis and preferably aligned therewith, which are connected to one another at the mutually facing ends by a spring center piece which rests on the second hinge lever, and of which the first spring assembly, which is between the first inner bearing arm and the first outer bearing arm is arranged, has a first spring end piece on an end facing away from the spring center piece, which rests on the first outer bearing arm, and of which the second spring package, which is arranged between the second inner bearing arm and the second outer bearing arm, on an end facing away from the spring center piece End has a second spring end piece which rests on the second outer bearing arm.
  • the invention it is therefore possible to advantageously integrate two spring assemblies into the folding door hinge without taking up additional space.
  • 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 which 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 helical design of the drive spring, it can exert a high spring force on the hinge levers within a large rotation range of around 180°. If desired, the drive spring can also be provided with a preload.
  • 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 folding door hinge still has a very slim structure.
  • the compressibility of the spring assemblies makes it easier to connect them to the first hinge lever. By compressing the spring assemblies, the spring end pieces are displaced axially and can automatically be guided more easily over a holding element provided on the first and second outer bearing arms using a tool or when the folding door hinge is actuated. 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 have a holding element which has a ramp or inclined flank facing the second hinge lever, 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 the holding channel behind the holding elements.
  • This process can be easily carried out by mounting the hinges on the door elements and then folding the door elements until they are ready 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.
  • a locking depression is thus formed between the holding element and the driver, 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 at least approximately corresponds to 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 packages take place 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 hold the bearing rollers, 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 easily connected to a cover device. 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, of which at least one holding module is held, which is held in a form-fitting, displaceable and lockable manner within the panel profile and which has a connecting element which is firmly or releasably connected to the hinge axis is.
  • 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 a aesthetically advantageous privacy protection is implemented and cannot be intervened in the door gap.
  • first lever end piece of the first hinge lever is provided with at least one first stop part
  • first lever end piece of the second hinge lever is provided with at least one second stop part.
  • the first and second stop parts are arranged on the first and second hinge levers in such a way that after the two hinge levers have rotated they are aligned with one another in opposite directions and form stop surfaces for the cover profile. After opening the folding door, the panel profile is always held in a desired orientation by means of the folding door hinge or the stop parts, in which the door gap is correctly covered.

  • Fig. 4 shows the folding door 11 of Fig. 3 with the first door element 111, which is separated from the folding door hinge 3 by a cut, 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 lies with the rollers 229 on the spacer plate 200 and holds the holding lever 22 at least approximately parallel to the mounting part 21.
  • the holding device 2 therefore only takes up little space within the door compartment 10.
  • 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, which has two spring assemblies 341, 342 connected to one another by a spring center piece 343, 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 rests 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.
  • 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 are pierced by the hinge axis 33, 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, by means of which the spring end pieces 3411, 3421 of the spring assemblies 341, 342 are held.
  • the second bearing arm 32 has a holding part or a holding lug 324, by means of which the spring center piece 343 is held.
  • the spring end pieces 3411, 3421 of the spring assemblies 341, 342 try to move the first hinge lever 31 clockwise about the hinge axis 33, which is a Axis of rotation x defined to rotate and the spring center piece 343 tries to rotate the second hinge lever 32 counterclockwise about the hinge axis 33.
  • 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 the folding door hinge 3 in an exploded view 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 can only accommodate the hinge axis 33, but not the bearing rollers 35.
  • 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 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 pushed through the bearing openings 31110, 31140 of the outer bearing arms 3111, 3114 and into the associated spring package 341 or 342 used.
  • 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 hooked into the holding elements 314 on the outer bearing arms 3111, 3114 and the hinge levers 31, 32 must be connected to the 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-shaped, which is why the spring end pieces 3411, 3421 have to be lifted 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 from the closed position in which they are aligned in one plane, preferably to the folded position in which they are aligned parallel to each other and can be rotated powerfully.
  • the force exerted by the drive spring is reduced to a minimum.
  • the movement of the door elements in this area is preferably dampened 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 strong one 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 from Fig. 5b , whose spring center piece 343 is suspended in the holding part 324 of the second hinge lever 32, but whose spring end pieces 3411, 3421 are not yet coupled to the first hinge lever 31.
  • 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.
  • the turns of the spring assemblies 341, 342 are 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 overcome the ramps 3141 of the holding elements 314 more easily.
  • 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 in a locking depression 328 (see Fig. 9 ) held 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 coupled in a simple manner to the folding door 11 or to the folding door hinges 3 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 door gap. On the other hand, it prevents anyone from reaching into the door gap and preventing injuries from occurring when operating the folding door.
  • Fig. 6a further shows an optional function of the two hinge levers 31, 32, which hold the panel device 4 or the panel profile 41 in a desired orientation within the opened 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 part 316 on at least 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 part 326.
  • Fig. 6b shows the folding door hinge 3 of Fig. 6a in a preferred embodiment with the drive spring 34, whose spring end pieces 3411, 3421 are coupled to the first hinge lever 31, but whose spring center piece 343 is not yet suspended in the holding part 324 of the second hinge lever 32.
  • the spring end pieces 3411, 3421 are preferably already suspended on a holding element 314 of the first hinge lever 31, while the second hinge lever 32 is not yet coupled to the drive spring 34 or to the spring center piece 343 before the folding door hinge 3 is put into operation for the first time.
  • the holding part 324 is preferably designed as a latching element, so that the spring center piece 343 can slide over the holding part 324 and lock behind it when the hinge arms 31, 32 are twisted together.
  • the holding part 324 is nose-shaped, hook-shaped or sawtooth-shaped.
  • the two hinge levers 31, 32 or the door elements 111, 112 are in turn rotated against each other.
  • the spring center piece 343 is guided over the holding part 324 and, due to its elasticity, may be slightly bent until it can snap into place behind the holding part 324.
  • the configurations of the folding door hinge 3 are from Fig. 6a and Fig. 6b combined with each other, so that the spring end pieces 3411, 3421 can be automatically coupled to the preferably ramp-shaped holding elements 314 and the spring center piece 343 of the drive spring 34 can be automatically coupled to the holding part 324 when the two hinge levers 31, 32 are rotated against each other for the first time.
