Abstract
Description
Technical Field
[0001] The invention relates to a damping hinge and a functional entity, in particular a piece of furniture or a building component, having at least one separate element, such as a door, a foldable door or a foldable sliding door, which is connected to at least one damping hinge. Background Art
[0002] In order to close a functional unit such as an opening of a room or furniture, a separating element is used, for example a foldable separating element, such as a foldable door or a foldable sliding door. Preferably, a separating element is provided which can be displaced into a door compartment or a parking space after the opening has been released.
[0003] US9284761B2 discloses a piece of furniture with a displacement device, via which a mounting profile connected to a foldable sliding door is displaceable within a door compartment. The foldable sliding door comprises two door elements, wherein a first door element is connected at the rear to the mounting profile via a mounting hinge and at the front to the rear of a second door element via a foldable door hinge, the second door element being connected at the front to a slide displaceable along a track, the track comprising two track sections which are aligned vertically to each other and connected to each other via a curved section, wherein the first track section extends into the door compartment and the second track section extends along the front of the piece of furniture. The mounting profile is held in vertical alignment by a supporting device and is provided with guide slides guided in guide rails on the upper and lower sides.
[0004] To close the piece of furniture, the foldable door extends from the door compartment and unfolds. In the closed position, the door elements are aligned with each other in a planar manner. To open the piece of furniture, the foldable door is folded back again, whereupon the door elements are retracted into the door compartment in the open position, preferably aligned parallel to each other.
[0005] In the closed position, the foldable door must be kept in a flat orientation so that the folding process is not automatically triggered. However, after opening the foldable door from the closed position, it would be desirable if the folding process could be performed automatically.
[0006] DE202018100262U1 discloses a pressure-actuated holding device, which helps to keep a foldable door in a closed position and fold the foldable door after the foldable door has been released from the closed position. The device includes a first mating component connected to a first door element of the foldable door and a second mating component connected to a second door element of the foldable door. Between the first mating component and the coupling device arranged on the second mating component, there is an ejector element movably connected to the first mating component and the coupling device. The displacement of the first accessory part relative to the coupling device is carried out by an accumulator, which is manually loaded by the user and acts on the ejector element. When the accumulator is used, the accumulator exerts a large force on the hardware, and the door elements of the foldable door are strongly abutted against each other or guided separately, so that the door elements may collide with each other or collide with fixed parts such as part of a cabinet, and produce a knocking noise.
[0007] US484628A discloses a hinge with a damping device, which is suitable for damping the movement of a door connected to the hinge. The damping device comprises a chamber in which a fluid is provided, into which a damping piston can be displaced, the damping piston being driven by a spindle, and the chamber comprising an opening through which the fluid can flow back when the damping piston is displaced. Such a hinge comprising a large number of device parts is complex in design and may easily require repairs, because the spindle inside the damping piston may cause wear and, after long-term operation, may no longer ensure a tight seal of the chamber into which the spindle extends.
[0008] US20050246863A1 discloses a damping hinge having a first hinge rod, the first hinge rod comprising a first rod sleeve at a first end and a first mounting portion connected to a door at a second end, and the damping hinge having a second hinge rod, the second hinge rod being rotatable about a hinge axis relative to the first hinge rod and comprising a second rod sleeve at a first end and a second mounting portion connected to a door frame at a second end. In addition, a hinge shaft is provided, which is arranged in the first and second rod sleeves in coaxial alignment with the hinge axis, and a damping device is provided, which is operable upon mutual rotation of the two hinge rods. The two rod sleeves comprise spiral elements directed towards each other, which interact with each other when the two hinge rods rotate and cause the two hinge rods to move axially relative to each other, thereby actuating the damping device and lifting the installed door at the same time, which is usually undesirable.
[0009] DE202022100493U1 discloses a damping hinge, which has a first hinge rod, which includes a first rod sleeve at the first end and a first mounting portion that can be connected to a first separation element at the second end, and the damping hinge has a second hinge rod, which can rotate around a hinge axis relative to the first hinge rod, and includes a second rod sleeve at the first end and a second mounting portion that can be connected to a second separation element at the second end. In addition, a hinge shaft is provided, which is arranged in the first rod sleeve and the second rod sleeve in a coaxial alignment with the hinge axis, and a damping device is provided, which can be actuated by the mutual rotation of the two hinge rods. The damping hinge also includes an axis core connected to the first rod sleeve, an axis sleeve and an air-oil damper with an actuating rod connected to the second rod sleeve. The outer circumferential surface of the axis core is provided with a spiral groove, and a pin connected to the actuating rod engages in the spiral groove. When the shaft core and the sleeve rotate relative to each other, the pin is guided along the spiral groove and the actuating rod is axially displaced, thereby actuating the gas-oil damper.
[0010] The damping hinge therefore comprises a number of device parts, in particular a shaft core, a shaft sleeve and an air-oil damper, which together form the hinge axis and are arranged inside the rod sleeve. Due to the large number of device parts, the effort required to manufacture and assemble the damping hinge is correspondingly high, and the production costs are also high. Due to the small size of the device parts that form the hinge axis, there are delicate device parts that are not able to transmit large forces. In addition, wear is to be expected when large forces are applied during prolonged operation. The spiral groove in the shaft core is relatively short, which is why the stroke of the actuating rod is also relatively small and an optimum damping effect cannot be achieved within this short stroke. Summary of the invention
[0011] The invention is therefore based on the object of providing an improved damping hinge equipped with a damping device. In addition, a functional unit with at least one separate element, in particular a piece of furniture or a building component, should be created, which is equipped with at least one such damping hinge.
[0012] The damping hinge should be strong and of simple design and should include as few components as possible. On the other hand, it should be possible to dimension the fixture components, which should be reduced in number, larger and therefore more robust.
[0013] The damping hinge should be able to transmit greater forces, so it should be able to reliably damp the movements of larger separation elements and show no signs of wear even over longer operating times and under higher loads.
[0014] With regard to the reduction of device components, it should be possible to create damping hinges with smaller dimensions while maintaining the advantageous properties with regard to damping and force transmission.
[0015] Thus, the damping hinge should require so little space that hardly any additional space is required compared to conventional hinges. The damping hinge should therefore hardly appear visually and be optimally integrated into functional units with separate elements, for example into folding door systems. Furthermore, it should be possible to advantageously replace a conventional hinge, i.e. an already installed hinge, with the inventive damping hinge, if necessary.
[0016] The damping hinge should comprise an improved damping effect, which is preferably adjustable.At least one actuating element of the damping device should be displaceable over a longer distance, so that advantageous damping characteristics can be achieved.
[0017] The damping joint should be able to damp a movement of at least one separation element connected thereto in one direction of rotation or preferably in both directions of rotation.
[0018] In a preferred embodiment, the damping hinge should also include a drive device, which allows the separation elements to be closed forcefully or allows the separation elements of the folding system or foldable door to be rotated forcefully towards or away from each other. Despite the additional integration of the drive device, the damping hinge should not take up significantly more space.
[0019] Via the inventive damping hinge or via several inventive damping hinges, a separate element of a functional entity such as a foldable door or a folding sliding door should be advantageously damped during the opening process and / or during the closing process and, if necessary, should also be automatically driven.
[0020] This object is achieved by a damping hinge according to claim 1 and a functional entity, optionally a piece of furniture or a building component, having a foldable door according to claim 15, the foldable door being equipped with at least one such damping hinge. Advantageous embodiments of the invention are defined in the further claims.
[0021] The damping hinge comprises: a first hinge rod, which comprises a first rod sleeve at a first end and a first mounting portion at a second end, the first mounting portion being connected or connectable to a first mounting component (e.g. a door frame or a hinge container), or being directly connected or connectable to a first separation element; a second hinge rod, which is rotatable around a hinge axis relative to the first hinge rod, and which comprises a second rod sleeve at a first end and a second mounting portion at both ends, the second mounting portion being connected or connectable to a second mounting component (e.g. a door frame or a hinge container), or being directly connected or connectable to a second separation element; a hinge shaft, which is arranged in the first rod sleeve and the second rod sleeve in coaxial alignment with the hinge axis; and a damping device with an actuating element, which can be actuated by the mutual rotation of the two hinge rods.
[0022] According to the present invention, at least one guide element is provided in the second rod sleeve, which spirally extends from one end of the second rod sleeve to the other end of the second rod sleeve; and the actuating rod is displaceably held by the hinge axis, the actuating rod is aligned parallel to or coaxially with the hinge axis, and the actuating rod includes a rod element and at least one track element connected to the rod element, the at least one track element interacts with the guide element so that when the two hinge rods rotate relative to each other, the actuating rod is axially displaceable against the actuating element of the damping device.
[0023] With the mutual rotation of the two hinge rods in one rotational direction and in the other rotational direction, the actuating rod is thus guided back and forth parallel to the hinge axis. Thus, the damping device of the damping hinge can be actuated by displacing the actuating rod in one direction. In a preferred embodiment, the damping hinge comprises two damping devices, which are aligned against the actuating rod on opposite sides along the hinge axis and can be actuated alternately. Thus, according to an embodiment of the damping hinge, the movement of a separating element connected to the damping hinge can be damped during an opening or closing operation or during an opening operation and a closing operation, while avoiding a vertical displacement of the separating element.
[0024] The damping hinge according to the invention is of simple and robust construction and comprises only a few device components. The reduced number of device components can be designed to be relatively large and robust.
[0025] Due to the robust construction with a reduced number of device components, the damping hinge allows the transmission of greater forces and the damping of the movements of larger and heavier separating elements.
[0026] Due to the more robust design of the fixing device components, signs of wear are avoided even after prolonged operation of the damping hinge.
[0027] Since the actuating rod moves parallel or coaxially with the hinge axis, only a small space is required. Therefore, the inventive damping hinge can be realized with relatively small dimensions.
[0028] The actuating rod can also be moved over a relatively long distance, so that a more favorable damping effect can be obtained and a larger damping device can be used.
[0029] The structure of the damping hinge is relatively simple, because the actuating rod can be slidably mounted and driven by simple means to actuate the damping device. Therefore, the damping hinge can be manufactured at low cost in a solid embodiment and operate for a long time without wear.
[0030] Various damping devices may be connected to the damping hinge or integrated into the damping hinge.Preferably, commercially available damping devices are provided so that the effort of integrating the damping device can be avoided and damping devices which are produced in large quantities and are therefore available on the market at low cost can be used.
[0031] Preferably, a damping device is used which comprises a damping piston which is displaceably mounted in a damping cylinder, which is connected to a reset element, such as a reset spring, and which is coupled or connectable to a rod-shaped actuating element which is aligned parallel or coaxially with the actuating rod. During the displacement of the damping piston, the medium (e.g. a gas or a fluid) is displaced in the damping cylinder, thereby achieving the desired damping effect. The damping piston can also be guided along an oil film. A magnetic damping device can also be used.
[0032] A damping device of this type can advantageously be connected to the damping hinge and aligned parallel or coaxially to the hinge axis, which likewise requires little space.
[0033] In a preferred embodiment, the hinge axis comprises a bearing channel, in which the actuating rod is displaceably mounted, and into which the rod-shaped actuating element of the damping device preferably projects. If the actuating rod does not extend out of the bearing channel, but the rod-shaped actuating element of the damping device is guided into the bearing channel, both the actuating rod and the rod-shaped actuating element of the damping device are guided in the bearing channel.
[0034] In a preferred embodiment, the actuating rod and the actuating element of the damping device are integrated in a single unit, which may have uniform dimensions or may have a first section associated with the actuating rod and a second section associated with the actuating element, which may have different dimensions.
[0035] Preferably, the actuating rod is axially displaceably held by a hinge shaft, but cannot rotate, and the hinge shaft is preferably connected to the first rod sleeve in a form-fitting or force-fitting manner. Therefore, when the second rod sleeve rotates relative to the first rod sleeve, the actuating rod does not rotate, but only axially displaces.
[0036] In another preferred embodiment, the hinge axis comprises a first shaft portion arranged in a first rod sleeve and a second shaft portion arranged in a second rod sleeve. At least one of the shaft portions is connected to a preferably sleeve-shaped receiving member, in which the damping device is held so that the actuating element faces the actuating rod. The sleeve-shaped receiving member is preferably aligned parallel or coaxially to the hinge axis and thus takes up little space. Furthermore, the extension of the hinge along the hinge axis is generally not critical, since the movement of the door element is not restricted.
[0037] Preferably, the diameter of the sleeve-shaped receiving member corresponds approximately to the diameter of the rod sleeve. Therefore, the receiving member is preferably designed as an extension of the rod sleeve. If two damping devices are provided, a first sleeve-shaped receiving member can be connected to the first rod sleeve or to the first end part of the hinge shaft, and a second sleeve-shaped receiving member can be connected to the second rod sleeve or to the second end part of the hinge shaft, so that the two receiving members are coaxially aligned and open toward the rod sleeve. The receiving member or receiving part can be connected to the rod sleeve or multiple rod sleeves or to the hinge shaft in a form-fitting or force-fitting manner, optionally threaded. Therefore, even in an embodiment with two damping devices, the damping hinge can be realized with small dimensions. When installing the damping hinge, it only needs to be ensured that it is installed at a sufficient distance from the upper edge or lower edge of the door element.
[0038] In a preferred embodiment, the second shaft section of the hinge shaft comprises at least one bearing gap extending outwardly from the bearing channel, the bearing gap extending parallel to the hinge axis, and at least one rod-shaped or cam-shaped track element protruding from the bearing gap and extending into the groove-shaped guide element of the second rod sleeve. Thus, during a rotation of the second rod sleeve, the actuating rod can be axially displaced within the hinge shaft without rotating. Preferably, a bearing block adjoins the track element, the bearing block being axially displaceable in the bearing gap of the second shaft section of the hinge shaft, but preferably remaining as a gap independent of rotation.
[0039] In a further preferred embodiment, the hinge shaft comprises a flange ring between the first shaft portion and the second shaft portion, separating the first rod sleeve from the second rod sleeve.
[0040] Preferably, at least one first coupling element, recess or extension is preferably arranged on the flange ring or a part corresponding thereto, which cooperates in a form-fitting manner with a second coupling element, extension or recess arranged on the facing side of the first rod sleeve, so that the first rod sleeve and the hinge axis cannot rotate relative to each other. Thus, the flange ring or a part corresponding thereto is connected to the first rod sleeve in a form-fitting manner and preferably without play with respect to mutual rotation. In a preferred embodiment, the first rod sleeve and the hinge axis can also form a unit.
[0041] The damping device is preferably displaceable in the receiving member via an adjusting member, such that the onset of the damping effect of the damping device is adjustable at a certain displacement of the actuating rod and thus at a certain mutual rotation of the hinge rod and the door element. The adjusting member is for example a threaded bolt rotatably held in the receiving member, the receiving member comprising at least one internal thread, such that the adjusting member is rotatable relative to the damping device.
[0042] Preferably, the end piece of the hinge shaft extending from the first rod sleeve and / or the second rod sleeve and adjacent to the first shaft portion or the second shaft portion is connected to the corresponding receiving member. Preferably, the receiving member and the corresponding end piece of the hinge shaft are provided with corresponding threaded elements so that the receiving member can be screwed onto the corresponding end piece of the hinge shaft.
[0043] Alternatively, the first rod sleeve and / or the second rod sleeve can also be provided with connecting elements or threaded elements, which can each be connected to the receiving member.
[0044] Each receiving member is provided with a damping device, as described above or as described below. Preferably, each damping device is adjustable, so that one damping device is adjustable for damping the opening or closing motion of the hinge, or both damping devices are adjustable for damping the opening and closing motion of the hinge.
[0045] If the damping device is provided only on one side, the exposed shaft section, usually the second shaft section, is connected to the cover. Preferably, a cover is provided which is connected to the hinge axis by screws or is screwed directly onto the hinge axis. For example, a hollow cylindrical cover is provided and can be screwed onto the facing shaft section. Preferably, the cover comprises an insert which can be inserted into the bearing channel of the hinge axis without any play. If the facing hinge axis consists only of segments of two or more parts (see Figure 6 ), which is particularly advantageous. The insert is, for example, cylindrical and coaxial with the hinge axis.
[0046] One or more guide elements are arranged on the inner side of the second shaft sleeve, which guide elements are preferably groove-shaped and extend in a spiral or helical manner away from one another.
[0047] In a preferred embodiment of the damping hinge, the two hinge rods are connected to each other via at least one drive spring. Thus, the damping hinge can be opened or closed automatically by the drive spring. It is also possible to install one or more drive springs which support the opening and closing process.
[0048] Preferably, the drive spring comprises at least one preferably cylindrical spring group with several spring coils, which surrounds a receiving member or a cover adjacent to the first rod sleeve or the second rod sleeve and is coupled to the first hinge rod by a first connection and to the second hinge rod by a second connection. If a cover is provided to hold the spring group, the cover is dimensioned accordingly, for example corresponding to the length of the spring group, and is preferably firmly connected (preferably threaded) to the rod sleeve of the hinge shaft or the like receiving member. Preferably, the cover is hollow cylindrical and is provided with an internal thread corresponding to the external thread of the end part of the hinge shaft.
[0049] In a particularly preferred embodiment, the drive spring comprises a first spring group having several spring coils, preferably cylindrical in shape, which surrounds a receiving member or cover adjacent to the first rod sleeve and is connected to the first hinge rod via a first connecting member and to the second hinge rod via a second connecting member, and the drive spring comprises a second spring group having several spring coils, preferably cylindrical in shape, which surrounds a receiving member or cover adjacent to the second rod sleeve and is connected to the first hinge rod via a first connecting member and to the second hinge rod via a second connecting member.
[0050] The corresponding first connecting members and / or second connecting members of the spring assembly may be connected to each other via a connecting rod or may be separated from each other.
[0051] According to the invention, two spring groups can thus be advantageously integrated into the damping hinge without taking up additional space. The two spring groups can exert a large force on the hinge lever, so that one or more disconnecting elements connected thereto are driven strongly after release from the end position.
[0052] The spring pack of the drive spring preferably comprises helical or thread-like turns which are in contact with one another or are at least partially spaced apart from one turn to another, such that the spring pack can be axially compressed.
[0053] Due to the screw-shaped embodiment, the drive spring can exert a high spring force on the hinge lever within a large rotation range of approximately 180°. If necessary, the drive spring can also be provided with a pretension.
[0054] The helical or screw-shaped embodiment of the drive spring allows an almost coaxial alignment of the spring group relative to the hinge axis and thus relative to the axis of rotation of the damping hinge, which is why only little space is taken up. Even if the coil of the spring group has a larger diameter, the result is still a very slender structure of the damping hinge.
[0055] In order to ensure that the spring pack is held frictionlessly, a bearing sleeve is preferably arranged between the preferably sleeve-shaped receiving member and the spring pack. For example, a bearing sleeve made of plastic is provided, which preferably comprises good sliding properties. Preferably, the bearing sleeve is made of a thermoplastic material, such as POM.
[0056] The functional entity is provided with a separation element held by the inventive damping hinge. Preferably, the functional entity comprises a foldable door or a folding sliding door having a separation element or a door element in combination with the inventive damping hinge. The movement of the door element is advantageously damped when the door element is moved into one end position or both end positions, and the movement of the door element is preferably driven when the door element is moved out of one end position or both end positions. If several damping devices are used, they are preferably selected individually according to the desired damping characteristics. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The foldable door 11 is slightly unfolded and can be completely folded and retracted into the door compartment 10, wherein the door elements 111, 112 are aligned parallel to each other, or can be completely unfolded and converted into a closed position, in which the two door elements 111, 112 are aligned at least approximately in one plane. In order to keep the foldable door 11 in the closed position and to easily release it from the closed position, one of the two door elements 111, 112 is preferably provided with a retaining device, which in the closed position is opposite to a fixed retaining element, which is for example connected to the upper plate 1B.
[0073] exist Figure 1 In the embodiment of the invention, the doors 11, 11' are preferably connected by means of the inventive damping hinge 2 to a mounting profile 12, respectively, which is held by a displacement device 9 and is displaceable in the associated door compartment 10. The door 11 is aligned parallel to the side wall 1A in front of the associated door compartment 10 and can subsequently be displaced into the door compartment 10. For displacement in the door compartment 10, each mounting profile 12 can also be provided with drive means.

The foldable door 11 is thus held at the front side via the guide carriage 5B, which is displaceable along the front side of the piece of furniture 1 in the unfolded state of the foldable door 11 and into the door compartment 10 in the folded state of the foldable door 11. The guide carriage 5B precedes the second separating element 112 in the direction of movement. By using the guide carriage 5B, the foldable door 11 can be easily unfolded and folded.

[0076] The invented damping hinge 2 includes two hinge rods 21, 22 connected to each other by a hinge shaft 23 (shown in dotted lines) and a damping device 26. The damping device 26 can be actuated by the mutual rotation of the two hinge rods 21, 22 via an actuating rod 24. The actuating rod 24 is axially displaceably mounted in the hinge shaft 23 and is driven when the damping hinge 2 is actuated.

[0078] The guide carriage 5B comprises support rollers 51 which can roll on support elements 151 of the guide rail 15B, and guide rollers 52 which are guided in guide channels 152 of the guide rail 15B. The guide rail 15B is shown extending 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. In order for the guide carriage 5B to follow this curve, the guide carriage 5B is connected to the second door element 112 via hinged parts 53, 54 of the drive body.
[0079] The mounting profile 12 is connected at the upper end to a support carriage 5A which is displaceable into the door compartment 10 along a support rail 15A via support rollers 51 and guide rollers 52. Figure 2 In FIG. 1 , the support carriage 5A has been guided to the stop device 7 at the front of the door compartment 10. The stop portion 59 of the support carriage 5A abuts against the buffer element 71 of the stop device 7. It is also shown that the stop device 7 is provided with a deflection roller 72 for guiding the first door element 111.
[0080] exist Figure 1 In this position, also shown in FIG. 1 , the foldable door 11 is fully extended from the door compartment 10 and can be deployed to close the furniture opening 100 (see FIG. 1 ). Figure 1 ).exist Figure 2 In the embodiment, the foldable door 11 has almost reached the closed position and can be moved into the closed position by manually pressing the foldable door 11 , preferably pressing the front edge 111 .
[0081] Thus, the two door elements 111, 112 are automatically transferred, for example, from a closed position to an open position or from an open position to a closed position, by driving the hinge 3. Thus, the functional entity 1 or the foldable sliding door 11 is easy to operate. However, in order to prevent the door elements 111, 112 from slamming open in the end position, the inventive damping hinge 2 is provided.
[0082] 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 a drive hinge. Therefore, a separate damping hinge and a drive hinge are not required.
[0083] Thus, the damping hinge 2 can be realized in various advantageous embodiments. In a first simple embodiment, the damping hinge 2 is provided for damping the movement of the connected separating element in the region of one end position. In another preferred embodiment, the damping hinge 2 is provided for damping the movement of the connected separating element in the region of two end positions. In a preferred embodiment, the damping hinges 2 are each equipped with at least one spring element 8, which comprises one preferably cylindrical spring group or two preferably cylindrical spring groups.
[0084] Figure 3 Shows Figure 2 The damping hinge 2 of the invention comprises two hinge rods 21, 22, each of which has a rod sleeve 210, 220, and the rod sleeve 210, 220 is connected to the hinge shaft 23 (shown by a dotted line, see Figure 5 ) are connected to each other, and the hinge shaft 23 is axially aligned with the hinge axis x of the damping hinge 2. The two hinge rods 21, 22 each include a mounting portion 211, 221 at the end opposite to the rod sleeve 210, 220, and the mounting portion 211, 221 can be connected to the separation element, for example, via a mounting component 4 such as a hinge container. The mounting component 4 is preferably connected to the corresponding mounting portion 211, 221 via a connecting screw 41. Alternatively, the connecting pieces 211, 221 can also be directly connected to the separation element.
[0085] On the lower side of the first rod sleeve 210, a sleeve-shaped receiving member 25 is mounted, in which the damping device 26 is arranged. In the preferred embodiment, the receiving member 25 is designed as a hollow cylinder. Preferably, the receiving member 25 includes an internal or external thread 251 at the end facing the first rod sleeve 210, via which the receiving member 25 can be connected to the end part of the first rod sleeve 210 or the hinge shaft 23. At the other end, the receiving member 25 preferably includes an internal thread 252, into which the adjustment member 27 (preferably a bolt) can be screwed, so as to axially shift and position the damping device 26 as required. In a preferred embodiment, a continuous internal thread can also be provided in the receiving member 25.
[0086] In a preferred embodiment, the damping means 26; 26A, 26B are provided in the associated receiving members 25; 25A, 25B (see Figure 3 and Figure 8a ) includes a device part 260 having an external thread that engages with the internal thread of the receiving member 25; 25A, 25B, so that the damping device 26; 26A, 26B is rotatable and axially displaceable. The damping device 26; 26A, 26B can thus be rotated to a desired position and then preferably fixed, for example via an adjustment member 27, which rotates against the damping device 26; 26A, 26B. The device part with the external thread is preferably a damping cylinder 260.
[0087] The damping device 26; 26A, 26B described in all embodiments of the inventive damping hinge 2 can preferably be moved to a specific position in order to be contacted by the actuating rod 24. The contact of the damping device 26; 26A, 26B can only occur in the end area of the hinge rod 21, 22 or in the entire rotation range. If two damping devices 26A, 26B are provided, as in Figure 8a In the embodiment of the present invention, the damping effect can be selectively adjusted to the corresponding contact of the damping means 26A, 26B by the actuating rod 24, so that the desired damping effect is achieved at each end position of the damping hinge 2. The damping effect can occur over the entire rotation range of the hinge rods 21, 22, or only before reaching the end position.
[0088] On the upper side of the second rod sleeve 220, a cover 28 is placed on the hinge shaft 23 and is connected to the hinge shaft 23 by means of a fixing screw 281. In a preferred embodiment, the cover 28 is cylindrical and is provided with an internal thread, via which the cover 28 can be screwed onto the upper end piece of the hinge shaft 23. Alternatively or additionally, the cover 28 comprises a central bolt 282, which can be inserted or screwed into a hole or a bearing channel in the hinge shaft 23. Alternatively, the cover 28 can also be connected to the second rod sleeve 220.
[0089] The actuating rod 24 is held axially displaceable by the hinge shaft 23 and is driven by the second rod sleeve 220. Preferably, the actuating rod 24 is displaceably mounted in a bearing channel 230 of the hinge shaft 23. During the axial displacement, the actuating rod 24 can cooperate with the actuating element 261 of the damping device 26 held in the receiving member 25.
[0090] The damping device 26 can be of any construction. Preferably, the damping device 26 comprises a damping cylinder 260 and a damping piston 262, which is connected to the actuating element 261 and can be displaced in the damping cylinder 260, for example to discharge a gas or liquid medium or to slide along an oil film. The movement of the damping piston 262 is therefore damped by the medium to be displaced or by the oil film, which is why the movement of the actuating rod 24 is damped and therefore also the mutual rotation of the hinge rods 21, 22 is damped. The damping device 26 also includes a return element 263, such as a return spring, via which the damping piston 262 is always returned. If the actuating rod 24 is firmly connected to the actuating element 261 of the damping device 26, the return of the damping piston 262 can also be achieved by the actuating rod 24.
[0091] In a preferred embodiment, the actuating rod 24 and the actuating element 261 are made in one piece, or are loosely or firmly coupled, for example, by at least one threaded element.
[0092] Figure 4a The present invention shows two hinge rods 21, 22 connected to each other by a hinge shaft 23, and a bearing 230 slidably mounted in the hinge shaft 23. Figure 3 The actuating rod 24 of the damping hinge 2 .
[0093] By passing through a quarter section of each of the first rod sleeve 210 and the second rod sleeve 220, the four main parts of the hinge shaft 23 are at least partially disclosed. The hinge shaft 23 includes a first shaft portion 231 retained in the first rod sleeve 210 and a second shaft portion 232 retained in the second rod sleeve 220, the second shaft portion 232 protruding upward beyond the second rod sleeve 220. The second shaft portion 232 is divided into two equal shaft segments 2321 by an axial section, the two shaft segments 2321 are opposite to each other, and the two shaft segments 2321 are separated from each other by a bearing passage 230 in the center and by bearing gaps 2320 on both sides. On the upper side of at least one shaft portion 2321, a threaded hole 2323 is provided, the threaded hole 2323 is used to receive a fixing screw 281, via which the cover 28 can be tightened (see Figure 3 ).
[0094] Between the first shaft portion 231 and the second shaft portion 232, the hinge axis 23 comprises a flange ring 233 extending outwards between the two rod sleeves 210, 220 and preferably having the same outer diameter as the two rod sleeves 210, 220. Facing the first rod sleeve 210, the flange ring 233 comprises a first coupling element 2330, which cooperates in a form-fitting manner with a second coupling element 2101 arranged on the upper side of the first rod 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 upper side of the first rod sleeve 210. The two coupling elements 2330, 2101 are joined in a form-fitting manner and preferably without play, so that the first hinge rod 21 and the hinge axis 23 cannot rotate relative to each other. In addition, the hinge shaft 23 includes a connecting portion 234 located at the lower side, which protrudes downward from the lower side of the first rod sleeve 210 and can be connected (preferably threaded) to the Figure 3 The outer diameter of the receiving member 25 and preferably the outer diameter of the cover 28 preferably corresponds to the outer diameter of the rod sleeves 210, 220, which is why the rod sleeves 210, 220 and the receiving member 25 form a uniform cylinder of small dimensions. Therefore, the damping hinge 2 can be advantageously used as a substitute for conventional hinges.
[0095] Figure 7 It is shown that the hinge shaft 23 is provided with a bearing channel 230, which extends coaxially with the hinge axis x, preferably through the entire hinge shaft 23. A rod element 241 of the actuating lever 24 is slidably mounted in the bearing channel 230. The rod element 241 comprises cam-shaped track elements 242 on both sides, with a bearing block 243 adjoining each track element.
[0096] Figure 4a It is shown that each track element 242 is guided in a guide element 2201 provided on the inner side or inner wall of the second rod sleeve 220. The guide elements 2201 are grooved in a spiral or helical pattern on the inner side of the second rod sleeve 220 and offset from each other, so that when the second rod sleeve 220 rotates relative to the first rod sleeve 210, or vice versa, the track element 242 follows the track-shaped guide element 2201 downward or upward, thereby displacing the actuating rod 24 relative to the damping device 26 and actuating the actuating rod 24.
[0097] The track element 242 protrudes from a bearing block 243, which is held in an associated bearing gap 2320 between the shaft segments 2321 of the second shaft portion 232 of the hinge shaft 23. Therefore, when the second rod sleeve 220 rotates, the track element 242 can only move parallel to the associated bearing gap 2320 and therefore only parallel to the hinge axis x.
[0098] Figure 4b The hinge axis 23 is shown without Figure 4a The two hinge rods 21, 22 and the actuating rod 24 of the damping hinge 2. In this illustration, the rod element 241, the track element 242 and the adjacent bearing block 243 of the actuating rod 24 are clearly visible.
[0099] Figure 5 Shows Figure 3 Exploded view of two separate hinge rods 21, 22, a hinge shaft 23 and an actuating rod 24 of a damping hinge 2, the damping hinge 2 having a cover 28 and a sleeve-shaped receiving member 25, into which a damping device 26 on the one hand and an adjustment member 27 on the other hand are inserted, via which the position of the damping device 26 in the receiving member 25 can be adjusted. It is shown that the connection part 234 comprises a thread and can therefore be screwed onto the receiving member 25.
[0100] Figure 6 Shows Figure 5 The damping hinge 2 of FIG. 2 comprises two separate hinge rods 21, 22, a hinge shaft 23 inserted into a first rod sleeve 210, and an actuating rod 24 displaceably mounted in a bearing channel 230 of the hinge shaft 23. In this illustration, a groove-shaped and spirally extending guide element 2201 arranged on the inner side of the second rod sleeve 220 is visible. In addition, it can be seen that the hinge shaft 23 is connected to the first rod sleeve 210 in a form-fitting manner via the coupling elements 2330, 2101, which prevents mutual rotation.
[0101] Figure 7 A longitudinal section of a hinge shaft 23 is shown, to which a receiving member 25 is connected, wherein a damping device 26 is held via an adjustment member 27, and an actuating rod 24 is slidably mounted in a bearing channel 230 of the hinge shaft 23. The sectioned portion is shown hatched. Only one of the shaft segments 2321 of the second shaft portion 232 of the hinge shaft 23 is shown, which is not affected by the longitudinal section.
[0102] The rod element 241 of the actuating rod 24 is shown to be guided in the bearing channel 230 of the hinge shaft 23 and to abut against the actuating element 261 of the damping device 26, which is also rod-shaped and also projects into the bearing channel 230 of the hinge shaft 23 in the region of the first rod sleeve 210 and is aligned coaxially with the rod element 241. Figure 3 )'s actuating element 261 is preferably supported by a spring 263 and pressed toward the rod element 241.
[0103] Figure 8a The actuator 24 is shown Figure 3In the damping hinge 2 of the invention, the actuating rod 24 can alternately actuate the damping devices 26A, 26B on each side, and the damping devices 26A, 26B are arranged in receiving members 25A, 25B. The receiving members 25A, 25B are connected to the rod sleeves 210, 220 or the end parts of the hinge shaft 23. Instead of the cover 28, the second receiving member 25B is therefore arranged on the upper side of the second rod sleeve 220, and the rod element 241 of the actuating rod 24 can extend into the second receiving member 25B. For example, when the hinge 2 is opened, the actuating rod 24 is guided upward against the damping device 26B, so that when the hinge 2 is closed, the actuating rod 24 is guided downward against the damping device 26A.
[0104] Figure 8b Shown is taken from Figure 8a The damping devices 26A, 26B of the damping hinge 2 and the actuating rod 24, the rod element 241 of the actuating rod 24 has been extended upwards, so that when the actuating rod 24 moves upwards, the upper damping device 26B can be actuated.
[0105] Fig. 9 The drive spring 8 is shown. Figure 3 A damping hinge 2 with an extended cover 28 and only one damping device 26, or a damping hinge 2 with a drive spring 8 is shown. Figure 8a The damping hinge 2 has two receiving members 25 and two damping devices 26A, 26B.
[0106] The drive spring 8 includes a first cylindrical spring group 81 surrounding the lower receiving member 25A and a second cylindrical spring group 82 surrounding the upper receiving member 25B or the cover 28. The first connecting members 811, 821 of the spring groups 81, 82 are connected to the first hinge rod 21, and the second connecting members 812, 822 of the spring groups 81, 82 are connected to the second hinge rod 22. In the preferred embodiment, the first connecting members 811, 821 are connected to each other by a first connecting rod 83, which is hooked into the retaining element 219 on the first hinge rod 21. The second connecting members 812, 822 are connected to each other by a second connecting rod 84, which can be hooked into the retaining element 229 on the second hinge rod 22.
[0107] The drive spring 8 is designed to be preferably strong. However, manual operation or tensioning of the drive spring 8 can be easily operated via one of the connecting rods 84. The second connecting rod 84 is hooked on the second hinge rod 22 via a hand movement, which is indicated by an arrow.
[0108] In the embodiment in which the retaining elements 219, 229 are used as locking elements, the coupling of the connecting rod 84 can also be achieved preferably and advantageously by turning the hinge rods 21, 22 or the separating elements 111, 112 connected to the hinge rods 21, 22 in the opposite direction. In this case, the second hinge rod 22 is turned clockwise until the second connecting rod 84 is guided over the second retaining element 229 and snaps into place.
[0109] In order to ensure that the spring groups 81 , 82 are advantageously supported, the plastic bearing sleeve 6 is preferably inserted between the receiving members 25A, 25B on the one hand (and the cover 28 if applicable) and the spring groups 81 , 82 on the other hand.
[0110] Thus, the inventive damping hinge 2 allows two mutually connected separation elements 111, 112 to be rotatably held against each other, and the movement of the separation elements 111, 112 is Figure 3 During the closing or opening of the embodiment or during Figure 8a The damping device 26 or the damping devices 26A, 26B can preferably be adjusted individually, as described above.
[0111] As mentioned above, the damping hinge 2 is preferably equipped with at least one drive spring 8, so as to avoid Figure 2 An additional drive hinge 3 is shown.
