Definitions

  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the damping hinge according to the invention can therefore be realized with relatively small dimensions.
  • 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.
  • damping devices can be connected to the damping hinge or integrated into the damping hinge.
  • 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.
  • a damping device 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.
  • a medium for example a gas or a fluid
  • 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.
  • 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.
  • 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.
  • the hinge shaft which is preferably connected to the first lever sleeve in a form-fitting or force-fitting manner.
  • 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.
  • 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.
  • 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.
  • 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.
  • the actuating rod can therefore be axially displaced within the hinge shaft without being rotated.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the exposed 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • bearing sleeves are preferably provided between the preferably sleeve-shaped receiving parts and the spring assemblies.

  • 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.
  • 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.
  • the actuating rod 24 is slidably mounted in a bearing channel 230 of the hinge shaft 23.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 .
  • the groove-shaped and spiral-shaped guide elements 2201 which are provided on the inside of the second lever sleeve 220, are visible.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • 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 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.
  • the damping device 26 or damping devices 26A, 26B can preferably be adjusted individually.
  • 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.
