Description

The invention relates to a damping hinge and a functional unit, in particular a piece of furniture, with at least one separating element, such as a door, folding door, or folding sliding door, which is connected to at least one damping hinge.

To close off functional units, such as openings in rooms or pieces of furniture, partitions are used, possibly foldable partitions such as folding doors or folding sliding doors. Partitions are preferably provided that can be moved into a door compartment or a parking space after the opening has been cleared, so that they do not cause a nuisance.

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.

To close the piece of furniture, the folding door is extended from the door compartment and unfolded. In the closed position, the door elements are aligned flat to one another. To open the piece of furniture, the folding door is folded back into place, with the door elements in an open position preferably aligned parallel to one another and retracted into the door compartment.

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 applying pressure and that supports both holding 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 that is connected to the first door element of the folding door and a second fitting part that 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 that is movably connected to the first fitting part and the coupling device. The first fitting part is adjusted relative to the coupling device via a force accumulator that can be loaded manually by the user and that acts against the ejection element. When using force accumulators that exert high forces on the fitting parts, the door elements of the folding door are forcefully guided against each other or apart so that the door elements collide with each other or with a stationary part, such as part of a cupboard, and can cause banging noises.

The US484628A discloses a hinge with a damping device which is suitable for damping movements of a door connected to the hinge. The damping device comprises a chamber in which a fluid is provided and into which a damping piston can be moved, which is driven by a spindle and which has openings through which the fluid can flow back when the damping piston is displaced. This hinge, which has a large number of device parts, is complex and may be susceptible to repairs, since the spindle within the damping piston can cause signs of wear and the tight seal of the chamber into which the spindle protrudes may no longer be guaranteed after a long period of operation.

The present invention is therefore based on the object of creating an improved damping hinge which is equipped with a damping device. Furthermore, a functional unit, in particular a piece of furniture, must be created with at least one separating element, which is equipped with at least one such damping hinge.

The damping hinge should only take up a small amount of space, meaning that there is hardly any additional space required compared to conventional hinges. The damping hinge should therefore hardly appear visually and should be able to be optimally integrated into a functional unit with separating elements, for example in a folding door system.

The damping device should have a good damping effect, which is preferably adjustable. The damping hinge should be able to dampen the movement of a separating element connected to it in one direction of rotation or in both directions of rotation.

In preferred embodiments, the damping hinge should also have a drive device which allows the dividing element to be forcefully closed or the dividing elements of a folding system or a folding door to be forcefully rotated against each other or apart. Despite the use of a drive device, the damping hinge should not take up significantly more space.

The damping hinge equipped with the damping device or the damping device and the drive device should be of simple construction and preferably hardly deviate from conventional hinges in terms of its construction. Conventional hinges, possibly already installed hinges, should therefore be able to be advantageously replaced by hinges according to the invention.

By means of a damping hinge according to the invention or by means of several damping hinges according to the invention, separating elements of a functional unit, such as a folding door or folding sliding door, should be able to be advantageously dampened and, if necessary, also driven during the opening process and/or the closing process.

This object is achieved with a damping hinge according to claim 1 and a functional unit, possibly a piece of furniture, with a folding door according to claim 15, which is equipped with at least one such damping hinge. Advantageous embodiments of the invention are specified in further claims.

• einen ersten Scharnierhebel, der an einem ersten Ende eine erste Hebelhülse und an einem zweiten Ende ein erstes Anschlussstück aufweist, das mit einem ersten Montageteil oder direkt mit einem Trennelement verbunden oder verbindbar ist;
• einen zweiten Scharnierhebel, der um eine Scharnierachse gegenüber dem ersten Scharnierhebel drehbar ist, und der an einem ersten Ende eine zweite Hebelhülse und an einem zweiten Ende ein zweites Anschlussstück aufweist, das mit einem zweiten Montageteil oder direkt mit einem Trennelement verbunden oder verbindbar ist;
• eine Scharnierwelle, die koaxial zur Scharnierachse ausgerichtet in der ersten und zweiten Hebelhülse angeordnet ist; und
• eine Dämpfungsvorrichtung, welche bei einer gegenseitigen Drehung der beiden Scharnierhebel betätigbar ist.

The damping hinge includes

• a first hinge lever having a first lever sleeve at a first end and a first connector at a second end which is or can be connected to a first mounting part or directly to a separating element;
• a second hinge lever which is rotatable about a hinge axis relative to the first hinge lever and which has a second lever sleeve at a first end and a second connector at a second end, which is or can be connected to a second mounting part or directly to a separating element;
• a hinge shaft arranged coaxially to the hinge axis in the first and second lever sleeves; and
• a damping device which can be activated by mutual rotation of the two hinge levers.

According to the invention, at least one guide element is provided in the second lever sleeve, which runs in a spiral from one end to the other end of the second lever sleeve; and that an actuating rod is held displaceably by the hinge shaft in a direction parallel or coaxial with the hinge axis, which has a rod element and at least one follower element connected to the rod element, which cooperates with the guide element in such a way that the actuating rod can be displaced axially against an actuating element of the damping device when the two hinge levers rotate relative to one another. When the two hinge levers rotate relative to one another, the actuating rod is thus guided along or parallel to the hinge axis against the actuating element of the damping device in order to actuate the damping device.

When the two hinge levers rotate mutually in one and the other direction of rotation, the actuating rod is guided back and forth parallel to the hinge axis, which is why a damping device can be actuated on one side or optionally two damping devices, which are arranged along the hinge axis and against each other or against the Actuating rod are aligned, can be operated alternately. A door element connected to the damping hinge can therefore, depending on the design of the damping hinge, be damped in movement either during the opening or closing process or during the opening and closing processes.

Since the actuating rod is moved parallel or coaxially to the hinge axis, only little space is required. The damping hinge according to the invention can therefore be realized with relatively small dimensions.

The design of the damping hinge is relatively simple, since the actuating rod can be slidably mounted and driven using simple means to actuate a damping device. Damping hinges can therefore be manufactured cost-effectively in a robust design and operated wear-free over a long service life.

Various damping devices can be connected to the damping hinge or integrated into the damping hinge. Preferably, a commercially available damping device is provided, so that the effort required to integrate the damping device can be avoided and a damping device can be used that is produced in large numbers and is therefore offered on the market at low cost.

Preferably, a damping device is used which comprises a damping piston which is slidably mounted within a damping cylinder, which is connected to a return element, such as a return spring, and which is coupled or can be coupled to the rod-shaped actuating element which is aligned parallel or coaxially to the actuating rod. When the damping piston is displaced, a medium, for example a gas or a fluid, is displaced within the damping cylinder, thereby achieving a desired damping effect. The damping piston can also be guided along an oil film. The use of magnetic damping devices is also possible.

A damping device of this type can advantageously be connected to the damping hinge and aligned parallel or coaxial to the hinge axis, which in turn requires only little space.

In preferred embodiments, the hinge shaft has a continuous bearing channel within which the actuating rod is slidably mounted and into which the rod-shaped actuating element of the damping device preferably projects. If the actuating rod is not guided out of the bearing channel, but the rod-shaped actuating element of the damping device is guided into the bearing channel, this results in mutual guidance of the actuating rod and the rod-shaped actuating element of the damping device.

Preferably, the actuating rod is held axially displaceable but not rotatable by the hinge shaft, which is preferably connected to the first lever sleeve in a form-fitting or force-fitting manner. When the second lever sleeve rotates relative to the first lever sleeve, the actuating rod is therefore not rotated but merely displaced axially.

In a further preferred embodiment, the hinge shaft has a first shaft part arranged in the first lever sleeve and a second shaft part arranged in the second lever sleeve, at least one of which is connected to a preferably sleeve-shaped receiving part, within which the damping device is held in such a way that the actuating element faces the actuating rod. The sleeve-shaped receiving part is preferably aligned parallel or coaxial to the hinge axis and therefore takes up little space. In addition, extending the hinge along the hinge axis is usually not critical, so that movements of the door elements are not restricted.

The diameter of the sleeve-shaped receiving part preferably corresponds approximately to the diameter of the lever sleeve, which is why the receiving part is preferably designed as an extension of the lever sleeve. If two damping devices are provided, a first sleeve-shaped receiving part can be connected to the first lever sleeve or to a first end piece of the hinge shaft and a second sleeve-shaped receiving part to the second lever sleeve or to a second end piece of the hinge shaft in such a way that the two receiving parts are coaxially aligned with one another and are open against the lever sleeves. The receiving part or the receiving parts can be positively or non-positively connected to the lever sleeve or lever sleeves or to the hinge shaft, if necessary screwed. Even in the embodiment with two damping devices, the damping hinge can therefore be implemented with small dimensions. When installing, just make sure that the damping hinge is installed at a sufficient distance from the top or bottom edge of the door elements.

In preferred embodiments, the second shaft part of the hinge shaft has at least one bearing gap that runs outward from the bearing channel, which extends parallel to the hinge axis and from which the at least one rod-shaped or cam-shaped follower element protrudes and protrudes into the groove-shaped guide element of the second lever sleeve. When the second lever sleeve rotates, the actuating rod can therefore be axially displaced within the hinge shaft without being rotated. Preferably, a bearing block adjoins the follower element, which is axially displaceable in the bearing gap of the second shaft part of the hinge shaft, but is preferably held free of play with respect to rotation.

In further preferred embodiments, the hinge shaft has a flange ring between the first shaft part and the second shaft part, which separates the first lever sleeve and the second lever sleeve from each other.

Preferably, the flange ring has at least one first coupling element, a recess or an extension, which interacts in a form-fitting manner with a second coupling element, an extension or a recess, on the facing side of the first lever sleeve in such a way that the first lever sleeve and the hinge shaft cannot rotate against one another are. The flange ring is therefore connected to the first lever sleeve in a form-fitting manner with respect to mutual rotation and preferably without play. In preferred embodiments, the first lever sleeve and the hinge shaft can also form a unit.

The damping device is preferably displaceable within the receiving part by means of an adjusting part, so that the start of the damping effect of the damping device can be set at a certain degree of displacement of the actuating rod and thus at a certain degree of mutual rotation of the hinge lever and door elements. The adjusting part is, for example, a threaded bolt which is rotatably held in the receiving part, which has at least one internal thread, so that the adjusting part can rotate against the damping device.

Preferably, an end piece of the hinge shaft which is led out of the first and/or second lever sleeve and which connects to the first or second shaft part is connected to one or each receiving part. Preferably, the mutually corresponding end pieces of the hinge shaft and the receiving part or the receiving parts are provided with mutually corresponding threaded elements, so that the receiving part or the receiving parts can be screwed to the end piece or the end pieces of the hinge shaft.

Alternatively, the first lever sleeve and/or the second lever sleeve can be provided with connecting elements or threaded elements, each of which can be connected to a receiving part.

Each receiving part is provided with a damping device, for example as described above or below. Preferably, each damping device is adjustable, so that one damping device can be adjusted for the opening process or the closing process or two damping devices can be adjusted for the opening process and the closing process of the damping hinge.

If a damping device is only provided on one side, the exposed shaft part, typically the second shaft part, is connected to a cover. A cover is preferably provided which is connected to the hinge axis by a screw or which is screwed directly to the hinge axis. For example, a cover is provided which is sleeve-shaped and can be screwed onto the facing shaft part. The cover preferably has an insert which can preferably be inserted into the bearing channel of the hinge shaft without play. This is particularly advantageous if the facing hinge shaft only consists of fragments of two or more parts (see Fig. 6 ). The insert is, for example, cylindrical and aligned coaxially with the hinge axis.

One or more guide elements are provided on the inside of the second lever sleeve, which are preferably groove-shaped and run spirally or helically offset from one another.

In preferred embodiments of the damping hinge, the two hinge levers are connected to one another by at least one drive spring. The damping hinge can therefore be opened or closed automatically by the drive spring. It is also possible to install one or more drive springs that support the opening and closing processes.

It is preferably provided that the drive spring has at least one preferably cylindrical spring package with several spring coils, which encloses the receiving part or the cover adjoining the first or second lever sleeve and is coupled to the first hinge lever with a first connecting piece and to the second hinge lever with a second connecting piece is. If the cover is provided for holding the spring assembly, it is dimensioned accordingly, for example corresponding length of the spring assembly, and preferably, like the receiving part, is firmly connected to the hinge shaft or a lever sleeve, preferably screwed. Preferably, the cover is sleeve-shaped and provided with an internal thread that corresponds to an external thread of an end piece of the hinge shaft.

• dass die Antriebsfeder ein vorzugsweise zylinderförmiges erstes Federpaket mit mehreren Federwindungen aufweist, welches das an die erste Hebelhülse anschliessende Aufnahmeteil oder die Abdeckung umschliesst und mit einem ersten Anschlussstück mit dem ersten Scharnierhebel und mit einem zweiten Anschlussstück mit dem zweiten Scharnierhebel gekoppelt ist, und
• dass die Antriebsfeder ein vorzugsweise zylinderförmiges zweites Federpaket mit mehreren Federwindungen aufweist, welches ein an die zweite Hebelhülse anschliessendes Aufnahmeteil oder die Abdeckung umschliesst und mit einem ersten Anschlussstück mit dem ersten Scharnierhebel und mit einem zweiten Anschlussstück mit dem zweiten Scharnierhebel gekoppelt ist.

In a particularly preferred embodiment it is provided

• that the drive spring has a preferably cylindrical first spring package with several spring coils, which is connected to the first lever sleeve subsequent receiving part or the cover encloses and is coupled to the first hinge lever with a first connecting piece and to the second hinge lever with a second connecting piece, and
• in that the drive spring has a preferably cylindrical second spring package with several spring coils, which encloses a receiving part or the cover adjoining the second lever sleeve and is coupled to the first hinge lever with a first connecting piece and to the second hinge lever with a second connecting piece.

The corresponding first connecting pieces and/or second connecting pieces of the spring assemblies can each be connected to one another or separated from one another by a connecting web.

According to the invention, it is thus possible to advantageously integrate two spring assemblies into the damping hinge without taking up additional space. The two spring assemblies are able to exert high forces on the hinge levers, so that a separating element or separating elements connected to them are powerfully driven after being released from an end position.

The spring assemblies of the drive spring preferably have helical or thread-shaped windings which lie against one another or are at least partially spaced from one another from winding to winding, so that the spring assemblies are axially compressible.

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 in relation to the hinge axis and thus the rotation axis of the damping hinge, which is why only a small amount of space is required. Even if the coils of the spring assemblies are given a larger diameter, the damping hinge still has a very slim design.

In order to keep the spring assemblies friction-free, bearing sleeves are preferably provided between the preferably sleeve-shaped receiving parts and the spring assemblies. For example, bearing sleeves are provided that are made of plastic, which preferably has good sliding properties. The bearing sleeves are preferably made of thermoplastic material such as POM.

The functional unit is provided with separating elements which are held by damping hinges according to the invention. The functional unit preferably has a folding door or folding sliding door with separating elements or door elements which are connected to damping hinges according to the invention. The movements of the door element or elements are advantageously dampened when moving into one end position or into both end positions and are preferably driven when moving out of one end position or out of both end positions. If several damping devices are used, these are preferably selected individually according to the desired damping properties.

Fig.1 shows a functional unit 1 according to the invention in the design of a piece of furniture 1 with a folding door 11, which can be inserted into a first door compartment 10, and with a one-piece door 11', which can be inserted into a second door compartment 10.

The piece of furniture 1 preferably has side walls 1A, an upper floor 1B, a lower floor 1C, an intermediate floor 1E and partition walls 1D on both sides, which delimit the door compartments 10 together with the side walls 1A.

The folding door 11 has a first separating element or door element 111, which is connected on one side by damping hinges 2 according to the invention to a mounting profile 12, and on the other side by damping hinges 2 according to the invention to a second separating element or door element 112, the dimensions of which preferably correspond to the dimensions of the first door element 111. The folding door 11 is slightly unfolded and can either be completely folded and retracted into the door compartment 10 with the door elements 111, 112 aligned parallel to one another, or completely unfolded and transferred to a closed position in which the two door elements 111, 112 are at least approximately aligned in one plane. In order that the folding door 11 remains held in the closed position and can be easily released from the closed position, one of the two door elements 111, 112 is preferably provided with a holding device which, in the closed position, is opposite a stationary holding element which is fastened, for example, to the top panel 1B.

In the design of Fig.1 the doors 11, 11' are preferably connected by damping hinges 2 according to the invention to a mounting profile 12 which is held by a sliding device 9 and within the associated door compartment 10. The doors 11 are aligned parallel to the side wall 1A in front of the associated door compartment 10 and can then be moved into the door compartment 10. For movement within the door compartment 10, each mounting profile 12 can also be provided with drive devices. The mounting profile 12 is preferably connected on the top to a support carriage 5A which can be moved along an associated guide rail 15A into the door compartment 10. The mounting profile 12 can also be connected on the bottom to a carriage which is guided in a guide rail.

In this preferred embodiment, the second separating element 112 of the folding door 11, the leading edge of which is connected to a guide drive 5B, is also guided by means of a guide rail 15B, which runs along the front of the piece of furniture 1 and along a curve into the door compartment 10. The folding door 11 is therefore held on the front side by means of the guide drive 5B, which can be moved along the front side of the piece of furniture 1 in the unfolded state of the folding door 11 and into the door compartment 10 in the folded state of the folding door 11. The guide drive 5B always runs ahead of the second separating element 112 in the displacement direction. By using the guide drive 5B, the folding door 11 can be unfolded and closed with little effort.

Fig.2 shows the back of the folding door 11 of the functional unit 1 of Fig.1 with the first door element 111, which in this embodiment is connected at the trailing edge by stop hinges 13 to the mounting profile 12 and at the leading edge by a damping hinge 2 according to the invention and a drive hinge 3 to the second door element 112, on the front side of which the guide drive 5B is mounted.

The damping hinge 2 according to the invention comprises two hinge levers 21, 22 connected to one another by a hinge shaft 23 (shown in dash-dotted lines) and a damping device 26, which can be actuated when the two hinge levers 21, 22 rotate mutually by means of an actuating rod 24, which is axially displaceable within the hinge shaft 23 stored and is driven by the second hinge lever 22 when the damping hinge 2 is actuated.

The drive hinge 3, which is the subject of an unpublished patent application, has two hinge levers 31, 32 connected to one another by a bearing shaft 33, which are additionally connected to one another by a drive spring 34.

The guide carriage 5B comprises support rollers 51 that can roll on a running plate 151 of the guide rail 15B, and guide rollers 52 that are guided in a guide channel 152 of the guide rail 15B. It is shown that the guide rail 15B runs along the front side of the piece of furniture 1 and around a curve into the door compartment 10 of the piece of furniture 1. So that the guide carriage 5B can follow this curve, it is connected to the second door element 112 by parts 53, 54 of a carriage body that are connected to one another in an articulated manner.

The mounting profile 12 is connected at the upper end to a support carriage 5A, which can be moved into the door compartment 10 along a guide rail 15A by means of support rollers 51 and guide rollers 52. In Fig. 2 the support gear 5A is guided up to a stop device 7 on the front of the door compartment 10. A stop part 59 of the support gear 5A rests on a buffer element 71 of the stop device 7. It is also shown that the stop device 7 is provided with deflection rollers 72, which serve to guide the first door element 111.

In this position, which is also in Fig.1 shown, the folding door 11 is fully extended from the door compartment 10 and can be unfolded to open the furniture opening 100 (see Fig.1 ) to complete. In Fig.2 the folding door 11 has almost reached the closing position and can be brought into the closing position by manual pressure on the folding door 11, preferably on the leading edge 111.

The two door elements 111, 112 are therefore automatically moved by the drive hinge 3, for example from a closed position to an open position or from an open position to a closed position, which is why the functional unit or the folding sliding door 1 is easy to operate. In order to prevent the door elements from slamming open in the end positions, the damping hinge 2 according to the invention is provided.

In a preferred embodiment (see Fig.9 ), the damping hinge 2 is additionally provided with a drive spring 8, so that in this embodiment it serves as a damping hinge and drive hinge and thus two hinges are not required.

The damping hinge 2 can therefore be implemented in various advantageous embodiments. In a first simple embodiment, the damping hinge 2 is provided for damping the movement of a connected separating element in the region of an end position. In a further preferred embodiment, the damping hinge 2 is provided for damping the Movement of a connected separating element in the region of both end positions is provided. In preferred embodiments, these damping hinges 2 are each equipped with at least one spring element 8, which has a preferably cylindrical spring assembly or two preferably cylindrical spring assemblies.

Fig.3 shows the inventive damping hinge 2 of Fig.2 , which comprises two hinge levers 21, 22, each with a lever sleeve 210, 220, which are connected by a hinge shaft 23 (shown in dash-dotted lines, see Fig.5 ), which is axially aligned with the hinge axis x of the damping hinge 2. The two hinge levers 21, 22 each have a connecting piece 211, 221 at the end opposite the lever sleeves 210, 220, which can be connected to a separating element, for example by means of an assembly part 4, such as a hinge cup. The assembly part 4 is preferably connected to the relevant connecting piece 211, 221 by means of a connecting screw 41. Alternatively, the connecting pieces 211, 221 can also be connected directly to a separating element.

On the underside of the first lever sleeve 210, a sleeve-shaped receiving part 25 is mounted, in which a damping device 26 is arranged. In this preferred embodiment, the receiving part 25 is designed as a hollow cylinder. The receiving part 25 preferably has an internal thread or an external thread 251 at the end facing the first lever sleeve 210, by means of which the receiving part 25 can be connected to the first lever sleeve 210 or to an end piece of the hinge shaft 23. At the other end, the receiving part 25 preferably has an internal thread 252, into which an adjusting part 27, preferably a threaded bolt, can be screwed in order to axially displace the damping device 26 and position it as desired. In preferred embodiments, a continuous internal thread can also be provided in the receiving part 25.

In a preferred embodiment, the damping device 26; 26A, 26B within the associated receiving part 25; 25A, 25B (see Fig. 3 and Fig. 8a ) has a device part 260 with an external thread that engages in an internal thread of the receiving part 25; 25A, 25B, so that the damping device 26; 26A, 26B is mounted so that it can rotate and move axially. The damping device 26; 26A, 26B can therefore be rotated to a desired position and subsequently fixed, for example, by means of the adjusting part 27, which is rotated against the damping device 26; 26A, 26B. The device part with the external area is preferably the damping cylinder 260.

In all described embodiments of the damping hinge 2 according to the invention, the damping device 26; 26A, 26B can therefore be moved to a specific location in order to be contacted by the actuating rod 24. The contacting of the damping device 26; 26A, 26B can only take place in the end region or over the entire rotation range of the hinge levers 21, 22. If two damping devices 26A, 26B are provided, as in the embodiment of Fig. 8a , the damping effect and the respective contacting of the damping devices 26A, 26B can be optionally adjusted by the actuating rod 24 so that the desired damping effect is achieved in each end position of the damping hinge 2. The damping effect can occur over the entire rotation range of the hinge levers 21, 22 or only before an end position is reached.

On the upper side of the second lever sleeve 220, a cover 28 is placed on the hinge shaft 23 and connected to it by a fastening screw 281. In preferred embodiments, the cover 28 is cylindrical and has an internal thread, by means of which the cover 28 can be screwed onto the upper end piece of the hinge shaft 23. Alternatively or additionally, the cover 28 has a center bolt 282, which can be screwed into a hole, possibly a bearing channel in the hinge shaft 23, if necessary. The cover 28 can alternatively also be connectable to the second lever sleeve 220.

An actuating rod 24 is held axially displaceably by the hinge shaft 23 and is driven by the second lever sleeve 220. Preferably, the actuating rod 24 is slidably mounted in a bearing channel 230 of the hinge shaft 23. During the axial displacement, the actuating rod 24 can cooperate with an actuating element 261 of the damping device 26, which is held in the receiving part 25.

The damping device 26 can be designed in any way. Preferably, the damping device 26 comprises a damping cylinder 260 and a damping piston 262, which is connected to the actuating element 261 and is displaceable within the damping piston 262, for example to displace a gaseous or liquid medium or to slide along an oil film. The movements of the damping piston 262 are therefore dampened by the medium to be displaced or by the oil film, which is why the movement of the actuating rod 24 and thus the mutual rotation of the hinge levers 21, 22 is also dampened. The damping device 26 also comprises a return element 263, such as a return spring, by means of which the Damping piston 262 is returned again. However, if the actuating rod 24 is firmly connected to the actuating element 261 of the damping device 26, the damping piston 262 can also be returned by the actuating rod 24.

Fig. 4a shows the two hinge levers 21, 22 connected to each other by the hinge shaft 23 and the actuating rod 24 of the damping hinge 2 of FIG. 1, which is slidably mounted in a bearing channel 230 of the hinge shaft 23. Fig.3 .

By making a quarter cut through the first and second lever sleeves 210, 220, four essential parts of the hinge shaft 23 are at least partially exposed. The hinge shaft 23 comprises a first shaft part 231 held in the first lever sleeve 210 and a second shaft part 232 held in the second lever sleeve 220, which protrudes upwards above the second lever sleeve 220. The second shaft part 232 is divided by an axial cut into two equal shaft segments 2321, which are located opposite one another and are separated from one another centrally by the bearing channel 230 and on both sides by bearing gaps 2320. A threaded bore 2323 is provided on the top of at least one of the shaft parts 2321, which serves to accommodate a fastening screw 281, by means of which the cover 28 (see Fig.3 ) can be attached.

Between the first and second shaft parts 231, 232, the hinge shaft 23 has a flange ring 233 which extends outwards between the two lever sleeves 210, 220 and which preferably has the same outer diameter as the two lever sleeves 210, 220. Facing the first lever sleeve 210, the flange ring 233 has a first coupling element 2330 which interacts in a form-fitting manner with a second coupling part 2101 which is provided on the top side of the first lever sleeve 210. The first coupling element 2330 is provided as a recess in the flange ring 233 and the second coupling element 2101 is provided as an extension on the top side of the first lever sleeve 210. The two coupling elements 2330, 2101 engage with each other in a form-fitting manner and preferably without play, so that the first hinge lever 21 and the hinge shaft 23 cannot rotate against each other. Furthermore, the hinge shaft 23 has a connecting part 234 on the underside, which projects downwards on the underside of the first lever sleeve 210 and is connected to the receiving part 25 of Fig.3 connectable, preferably screwable. The outer diameter of the receiving part 25 preferably corresponds to the outer diameter of the lever sleeves 210, 220, which is why the lever sleeves 210, 220 and the receiving part 25 form a uniform cylinder with small dimensions. The damping hinge 2 can therefore advantageously be used as a replacement for conventional hinges.

Fig.7 shows that the hinge shaft 23 is provided with a bearing channel 230 which extends coaxially to the hinge axis x, preferably through the entire hinge shaft 23. A rod element 241 of an actuating rod 24 is slidably mounted within the bearing channel 230. The rod element 241 has cam-shaped follower elements 242 on both sides, to each of which a bearing block 243 is connected.

Fig. 4a shows that the follower elements 242 are guided in guide elements 2201, which are provided on the inside or inner wall of the second lever sleeve 220. The guide elements 2201 are groove-shaped and run offset from one another in a spiral or helical manner on the inside of the second lever sleeve 220. When the second lever sleeve 220 rotates, the follower elements 242 follow the track-shaped guide elements 2201 downwards or upwards, whereby the actuating rod 24 is displaced relative to the damping device 26 and can actuate it.

The follower elements 242 protrude from a bearing block 243, which is held in the associated bearing gap 2320 between the shaft segments 2321 of the second shaft part 232 of the hinge shaft 23. When the second lever sleeve 220 rotates, the follower elements 242 can therefore only be moved parallel to the associated bearing gap 2320 and thus only parallel to the hinge axis x.

Fig. 4b shows the two hinge levers 21, 22 and the actuating rod 24 of the damping hinge 2 of Fig. 4a without the hinge shaft 23. In this illustration, the rod element 241, the follower element 242 and the adjacent bearing block 243 of the actuating rod 24 are clearly visible.

Fig.5 shows in exploded view the two separate hinge levers 21, 22, the hinge shaft 23, and the actuating rod 24 of the damping hinge 2 of Fig.3 , with the cover 28 and the sleeve-shaped receiving part 25, into which the damping device 26 and an adjusting part 27 are inserted, by means of which the position of the damping device 26 in the receiving part 25 can be adjusted. It is shown that the connecting part 234 has a thread and can therefore be screwed to the receiving part 25.

Fig. 6 shows the two separate hinge levers 21, 22, the hinge shaft 23 inserted into the first lever sleeve 210 and the actuating rod 24 of the damping hinge 2, which is slidably mounted in a bearing channel 230 of the hinge shaft 23 Fig. 5 . In this illustration, the groove-shaped and spiral-shaped guide elements 2201, which are provided on the inside of the second lever sleeve 220, are visible. Furthermore, it can be seen that the hinge shaft 23 is positively coupled to the first lever sleeve 210 with respect to mutual rotation by the coupling elements 2330, 2101.

Fig.7 shows in a longitudinal section the hinge shaft 23 with the associated receiving part 25 in which the damping device 26 is held by means of the adjusting part 27, and with the actuating rod 24, which is slidably mounted in the bearing channel 230 of the hinge shaft 23. The sectioned parts are shown hatched. Of the second shaft part 232 of the hinge shaft 23, only one of the shaft segments 2321 is shown, which is not affected by the longitudinal section.

It is shown that the rod element 241 of the actuating rod 24 is guided in the bearing channel 230 of the hinge shaft 23 and rests on the actuating element 261 of the damping device 26, which is also rod-shaped and also protrudes into the bearing channel 230 of the hinge shaft 23 in the area of the first lever sleeve 210 and is aligned coaxially with the rod element 241.

Fig. 8a shows the inventive damping hinge 2 of Fig.3 with an actuating rod 24 which can alternately actuate a damping device 26A, 26B on each side, which are arranged in receiving parts 25A, 25B. The receiving parts 25A, 25B are connected to the lever sleeves 210, 220 or to end pieces of the hinge shaft 23. Instead of the cover 28, a second receiving part 25B is thus provided on the top of the second lever sleeve 220, into which the rod element 241 of the actuating rod 24 can extend. When the hinge 2 is opened, the actuating rod 24 is guided upwards against the damping device 26B, for example, so that the actuating rod 24 is guided downwards against the damping device 26A when the hinge 2 is closed.

Fig. 8b shows the one from the damping hinge 2 of Fig. 8a removed damping devices 26A, 26B and the actuating rod 24, the rod element 241 of which was extended upwards, so that during a displacement of the actuating rod 24 upwards, the upper damping device 26B can be actuated.

Fig.9 shows the damping hinge 2 equipped with a drive spring 8 of Fig.3 with an extended cover 28 and only one damping device 26 or the damping hinge 2 equipped with a drive spring 8 of Fig. 8a with two receiving parts 25 and two damping devices 26A, 26B.

The drive spring 8 has a first cylindrical spring package 81, which encloses the lower receiving part 25A, and a second cylindrical spring package 82, which encloses the upper receiving part 25B or the cover 28. The first connecting pieces 811, 821 of the spring assemblies 81, 82 are connected to the first hinge lever 21 and the second connecting pieces 812, 822 of the spring assemblies 81, 82 are connected to the second hinge lever 22. In this preferred embodiment, the first connecting pieces 811, 821 are connected to one another by a first connecting web 83, which is suspended in a holding element 219 on the first hinge lever 21. The second connecting pieces 812, 822 are connected to one another by a second connecting web 84, which can be hooked into a holding element 229 on the second hinge lever 22. The drive spring 8 is preferably designed to be powerful, which is why the manual operation or tensioning of the drive spring 8 can be easily carried out using one of the connecting webs 84. The hand movement by which the second connecting web 84 is hooked onto the second hinge lever 22 is symbolized by an arrow

When the holding elements 219, 229 are designed as latching elements, the coupling of the connecting web 84 can preferably also be advantageously carried out by rotating the hinge levers 21, 22 or the separating elements 111, 112 connected thereto. In this case, the second hinge lever 22 is rotated clockwise until the second connecting web 84 is guided over the second holding element 229 and snaps into place.

So that the spring assemblies 81, 82 are mounted advantageously, bearing sleeves 6 made of plastic are preferably inserted between the receiving parts 25A, 25B, possibly the cover 28 on the one hand and the spring assemblies 81, 82 on the other hand.

The damping hinge 2 according to the invention thus makes it possible to hold two interconnected separating elements 111, 112 rotatable against each other and to control their movements in the configuration of Fig.3 either when closing or when opening or in the design of Fig. 8a to dampen both when closing and when opening. The damping can take place only in the end areas or over the entire rotation range of the damping hinge 2. As described, the damping device 26 or damping devices 26A, 26B can preferably be adjusted individually.

As described, the damping hinge 2 is preferably equipped with at least one drive spring 8, so that an additional drive hinge 3, as shown in Fig. 2 shown can be omitted.
