Description

The present invention relates to a furniture hinge with a stop member and hinged thereto hinged pot for attachment to furniture parts, and with a damping device for damping a relative movement between the stop member and the hinge cup, wherein the damping device is arranged in or on the hinge cup.

Furthermore, the invention relates to a piece of furniture with at least one furniture hinge of the type to be described.

Furniture hinges with a hinge cup and with a damping device arranged in or on the hinge cup are already known according to the prior art. As an example of this is the AT 6499 the applicant, the DE 25 39 954 A1 , the DE 10 2007 047 287 A1 , the DE 10 2006 047 315 A1 or the EP 1 469 153 A1 mentioned. Damping devices with a linear damping stroke having piston usually have a path-dependent damping function, ie that the degree of damping depends on the available damping stroke of the piston. Thus, therefore, a sufficient Dämpfweg provided in order to achieve the desired smooth damping relative movement of the two abutment parts to each other. A particular challenge therefore is to arrange the damping device as space-saving as possible, but at the same time to ensure a sufficient damping stroke and thus a satisfactory damping effect of the furniture hinge.

From the WO 2007/131933 A1 a furniture hinge with a damping device has become known, wherein the housing of the damping device via cooperating fastening means (in the form of a tab and a stop surface) is held within the hinge cup. The damping device must be used as a result of the connection of a hinge lever of the hinge with a slide of the damping device already in the hinge pot and fixed from the factory.

The prioritized, but post-published WO 2009/094272 A1 describes a furniture hinge with a damping device used in the hinge cup, which is fixed by holding snapper relative to the hinge cup bottom. Not shown is a hinge in which the damping device can be inserted from above into the hinge cup, hinged together with the stop member and hinge cup. For a retrofit of the damping device, it is obviously necessary to perform a disassembly of the hinge.

Object of the present invention is to propose a furniture hinge of the type mentioned, wherein the damping device is space-saving, efficient and retrofittable.

This is inventively achieved in an advantageous embodiment in that the damping device has a housing with first attachment means and second hinge means are arranged on the hinge cup, wherein the housing of the damping device can be inserted from above into the hinge cup and arranged substantially completely in mounting position within the hinge cup wherein the housing of the damping device and the hinge cup are connectable to each other via the first and second fastening means in this mounting position.

By the definition "insertable from above into the hinge cup" is meant the insertion of the housing of the damping device in a direction of movement which runs essentially perpendicular to the bottom of the hinge cup.

The proposed invention, it is possible to completely arrange the housing of the damping device within the hinge cup, wherein the housing preferably does not protrude beyond the hinge cup in this mounting position, ie the entire assembly of the damping device in the assembled state completely between the bottom of the hinge cup and the is formed by the hinge cup opening formed plane. Via the first and second fastening means, the housing of the damping device can be mounted relative to the hinge cup and disassembled from this. In an expedient embodiment of the invention can thus be provided that the housing of the damping device by the first and the second fastening means on or in the hinge cup detachable fastened, preferably without tools mounted and preferably without tools can be removed, is.

The damping device may comprise a slider 11a which is movable relative to the housing, wherein the first fastening means are formed on the slider so that the housing of the damping device can be detachably connected to the hinge cup indirectly via the slider.

According to a preferred embodiment of the invention can be provided that the first and second fastening means are designed as self-locking latching connection. Such a latching connection allows the automatic latching between the housing of the damping device and the hinge cup in the course of the introduction of the housing in the hinge cup, without requiring additional locking means must be actuated by the user for fixing. The first and second fastening means can jointly form a snap connection, so that the damping device can be clipped into the hinge cup as a closed structural unit. In one possible embodiment of the invention, the first or the second fastening means may comprise at least one movable or movable locking element, by means of which the housing can be fixed relative to the hinge cup. An expedient embodiment is characterized in that the locking element is resilient, wherein the connection between the first and second fastening means by pressure against the resilient action of the locking element is releasable.

In one possible embodiment it can be provided that the locking element is arranged on the housing of the damping device and engages in an assembled position in an opening or on a latching edge of the hinge cup. In kinematic reversal, it is also possible that the locking element is mounted on the hinge cup and engages in an assembled position in a housing arranged on the damping device opening or locking edge.

It can be provided that the first and second fastening means between the housing of the damping device and a side wall of the hinge cup are effective. Alternatively or additionally, it may also be possible that the first and second fastening means between the housing of the damping device and the bottom of the hinge cup or a hinge cup associated support member (in particular a mounting pin) are effective.

It is possible that the fastening pin is provided for supporting a spring, which presses the hinge cup relative to the stop member in the full closed position and / or in the full open position. This mounting pin can thus also be used as a support element for the housing of the damping device. The mounting pin can extend at least in sections within the hinge cup, wherein the mounting pin has a recess which is provided for receiving the housing of the damping device - in particular for receiving and guiding a linearly movable slide of the damping device.

In a preferred embodiment of the invention can be provided that the housing has a peripheral surface whose shape is partially adapted to the inner shape of the hinge cup. In other words, the outer shape and size of the housing of the damping device is adapted to the shape and size of the interior of the hinge cup. As a result, a defined pre-positioning of the housing is possible, after positioning the first and second fastening means are connected to each other, wherein the housing of the damping device is positively and / or non-positively fixed relative to the hinge cup. By the hinge cup adapted contour of the housing of the damping device this is in mounting position mostly directly to the inner wall of the hinge cup, wherein the arrangement within the hinge cup in a visually very inconspicuous manner and the risk of dirt deposits between the housing of the damping device and the inner wall of the hinge cup is reduced.

For easy disassembly of the damping device relative to the hinge cup, a release member may be provided, through which the connection between the first and second fastening means is releasable, whereupon the housing of the damping device is removable from the hinge cup. It may be advantageous if the release part is arranged on the housing of the damping device. The release part can be manually and / or be moved by means of a tool in a release position, whereby the housing of the damping device is removable from the hinge cup.

By the first and second fastening means existing hinge assemblies can be retrofitted with a damping device later, the retrofitting can already be done in the factory. In an already factory-mounted attachment of the damping device existing production lines can be maintained, so that the attachment of the damping device requires only a very small effort required. Of course, by a user subsequent assembly and / or disassembly of the damping device can be made to existing hinge assemblies. The damping device can also be inserted into the hinge cup and can be fixed relative to the hinge cup via the first and second fastening means when the hinge lever of the hinge is hinged to the hinge cup.

To achieve a particularly compact construction, it may be favorable if the damping device has a first and a second fluid chamber filled with damping fluid, which are connected to one another by a channel. It may be expedient that in the first fluid chamber, a piston is plunged, through which the volume of the first fluid chamber is variable and wherein in the second fluid chamber, a device is arranged by the inflow or outflow of damping fluid into and out of the second Fluid chamber for changing the volume of the second fluid chamber is deformable or movable.

The two fluid chambers are thus connected in series and communicate via at least one channel in fluid conducting connection. The damping fluid of the first fluid chamber displaced by the first piston during the damping stroke must also flow through the passage into the second fluid chamber, apart from any residual compressibility of the damping fluid, the volume of the second fluid chamber being variable by the fluid pressure. The second fluid chamber thus forms a compensating space for the displaced damping fluid which is variable during the compression or decompression. The second fluid chamber can be arranged relative to the first fluid chamber in a very compact design, whereby particularly small structures of the damping device can be realized.

According to one embodiment of the invention, the said device may comprise a deformable piece of material arranged in the second fluid chamber or a piston displaceable in the second fluid chamber, whereby the volume of the second fluid chamber can be changed during the inflow or outflow of damping fluid. Thus, instead of the second piston in the second fluid chamber, a deformable piece of material made of a compressible material, such as e.g. Sponge rubber is made. The arrangement of the second piston can - but need not - omitted, since the provision of the first piston generates a negative pressure and thus a suction effect to allow the existing in the second fluid chamber damping fluid after attenuation at least partially flow back into the first fluid chamber.

According to one exemplary embodiment of the invention, the first fluid chamber has a first longitudinal axis and the second fluid chamber has a second longitudinal axis, wherein the first longitudinal axis and the second longitudinal axis of the fluid chambers can run parallel to one another or can also run transversely to one another. In principle, the channel connecting the two fluid chambers can also have a very short length (for example in the form of a hole in the function of an overflow opening). It is preferably provided that the channel connecting the two fluid chambers extends from the bottom region of the first fluid chamber to the inlet region of the second fluid chamber.

According to a possible embodiment of the invention, it may be provided that the damping device has a first piston and at least one second piston with linear damping stroke, wherein the direction of the linear damping stroke of the first piston relative to the linear damping stroke of the second piston is substantially parallel or transverse.

The first and second pistons are each displaceably guided in a fluid chamber, wherein the two fluid chambers are connected in series and flow-connected via the at least one channel. In this way, the damping stroke of the first piston and thus the size of the damping device can be reduced. The damping medium displaced by the first piston during the damping stroke The first fluid chamber flows through the tapered passage into the second fluid chamber, whereby the flow resistance of the existing in the first fluid chamber damping fluid is increased. Due to the resulting small design of the damping device, this can be particularly easy to find within the hinge cup recording.

According to a possible embodiment of the invention can be provided that the direction of the linear damping stroke of the first piston relative to the linear damping stroke of the second piston forms an angle α, wherein the angle α is between 70 ° and 110 °. In a preferred embodiment of the invention can also be provided that the direction of the linear damping stroke of the first piston extends at right angles relative to the linear damping stroke of the second piston.

The two fluid chambers may be formed in each case by the interior of a fluid cylinder according to a possible embodiment. However, particularly preferred is the formation of the fluid chambers in a housing of the damping device, so that the additional provision of fluid cylinders is not absolutely necessary. In this way, the damping device can be realized with a reduced number of components to be used.

The damping device may comprise an actuating element, by which the force is introduced into the damping device, wherein the actuating element during the hinge movement of one of the stop members or of a arranged between the stop members articulated lever is acted upon. The pivotable during the hinge movement hinge lever is submersible in the hinge cup towards the end of the closing movement of the furniture hinge. A possible embodiment provides that at least one of the two pistons is integrally connected to the actuating element. Due to the integral design of the actuating element with one of the pistons, the number of components is reduced, wherein additionally a direct introduction of force into the damping device can take place.

The actuating element may comprise a linearly displaceable slider according to a possible embodiment, the starting from a predetermined relative position the abutment parts can be acted upon by one of the abutment parts or by an articulated lever arranged between the abutment parts. The slider may be formed as a sliding wedge with an inclined surface, which is acted upon by one of the stop members or the hinge lever towards the end of the closing movement and / or towards the end of the opening movement.

In order to avoid an undesirable tilting of the sliding slide during the damping process, it may be advantageous if the slide has a guide - preferably in the form of a slot -, whereby the slide is displaceable relative to a hinge cup arranged on the fastening pin. The mounting pin can be provided at the same time for mounting a spring device which presses the two stop members in an end position. The spring device can press the stop parts in the direction of the full open position and / or in the direction of the full closed position, wherein the spring action begins only towards the end of the closing operation and / or towards the end of the opening process. The proposed damping device is thus expediently provided to damp an opening movement and / or a closing movement over a partial region of the entire opening angle range of the two stop parts to each other.

Fig. 1 shows a perspective view of a piece of furniture 1 with a furniture body 2, wherein a movable furniture part 3 is attached in the form of a hinged door on furniture hinges 4 according to the invention on a furniture body 2 arranged or formed frame 2a. The movable furniture part 3 is pivotally mounted between a closed the furniture body 2 closing position and an open position.

Fig. 2 shows a possible embodiment of a furniture hinge 4, wherein a first stop member 5 is assigned to the furniture body 2 and a second stop member 6 to the movable furniture part 3. The body-side stop member 5 may - as in the figure shown - be L-shaped or U-shaped and in mounting position the in Fig. 1 at least partially embrace frame shown 2a. The stop member 5 may of course be formed as a hinge arm. The second stop member 6 has a hinge cup 6a, which is retractable in a provided on the movable furniture part 3 bore. The hinge cup 6a has a flange 6b, which rests in the mounting position on the inside of the movable furniture part 3. Between the stop member 5 and the hinge cup 6a, a hinge lever 7 is arranged, which is mounted relative to the first stop member 5 displaceable and / or tiltable via an adjusting device 8. The articulated lever 7 is articulated on the other side on the hinge cup 6a on a rotation axis. The furniture hinge 4 is thus formed in the embodiment shown as Einachsscharnier. Visible is a spring device 9, which presses the two stop parts 5, 6 in the direction of the closed position or holds the stop members 5, 6 in a closed position. A damping device 10 is substantially completely disposed within the hinge cup 6a, wherein the damping device 10 for damping a relative movement of the two stop members 5, 6 to each other over a partial path of the maximum opening angle of the two stop members 5, 6 is provided. The damping device 10 has an actuating element 11 in the form of a linearly displaceable slide 11 a, which is acted upon by the toggle lever 7 towards the end of the closing movement of the furniture hinge 6 and thereby introduces the force into the damping device 10.

Fig. 3a shows a side view of the open furniture hinge 4 in the mounted state. The first stop member 5 is fixed to the frame 2 a of the furniture body 2, while the second stop member 6 is mounted with the hinge cup 6 a on the movable furniture part 3. Visible is the damping device 10, whose arcuate peripheral edge is at least partially adapted to the contour of the inner wall of the hinge cup 6a. The housing of the damping device 10 may be formed in plan view, for example, at least approximately mushroom-shaped. The last of the hinge movement pivoted joint lever 7 applied towards the end of the closing movement of the linearly movable slide 11 a, whereby the damping process is initiated. Shown is also the spring device 9, which assumes the function of a closing spring in the illustrated embodiment.

Fig. 3b shows a vertical section along the in Fig. 3a drawn arrows. The body-side stop member 5 is fixed by a screw 12 on the frame 2a. The hinge cup 6a is recessed in the movable furniture part 3, wherein the damping device 10 is fully integrated with the slider 11a in the hinge cup 6a. The slider 11a has an inclined surface 15, which is acted upon by the toggle lever 7 from a predetermined relative position of the stop members 5 and 6 to each other. The slider 11a has a slot 13, so that the slider 11a is slidably guided in a guided manner during the damping process relative to a fixing pin 14 fixedly arranged on the hinge cup. In the figure shown, the articulated lever 7 is in a position spaced from the inclined surface 15 of the slider 11 a position.

In Fig. 4a is one too Fig. 3a shown analog representation, with the difference that the movable furniture part 3 has been moved further in the closing direction and the hinge lever 7 now impinges on the slide 11a of the damping device 10, which in particular from the sectional view Fig. 4b good. The cranked articulated lever 7 now strikes against the inclined surface 15 of the slider 11a, whereby the damping process is initiated.

In Fig. 5a the complete closed position of the movable furniture part 3 is shown relative to the frame 2a, wherein the damping process is already completed. In the sectional view according to Fig. 5b It can be seen that the articulated lever 7 has moved the slider 11a on the inclined surface 15, so that the stationary mounting pin 14 in comparison to Fig. 4b abuts the opposite end of the slot 13. Due to the movement of the slider 11 a, the movement to be damped was introduced into the damping device 10.

Fig. 6 shows the fully integrated into the hinge cup 6a damping device 10, the housing 10a is at least partially adapted to the inner shape of the hinge cup 6a. The housing 10a has an arcuate peripheral edge, which rests in the mounting position at least partially against the inner wall of the hinge cup 6a. The slider 11a with its inclined surface 15 and its slot 13 is slidably mounted relative to the housing 10a during the damping stroke and during the return stroke.

Fig. 7a shows a horizontal section of the damping device 10 in a perspective view, based on the principle of operation of the damping device 10 is to be explained. Evident is a first fluid chamber 16, in which a first piston 16a is guided linearly displaceable. The damping device 10 is designed as a fluid damper, wherein the first fluid chamber 16 is filled with a damping fluid (for example, a liquid, an oil or, in the case of a corresponding size, also with air). A seal 17a seals the first piston 16a from the inner wall of the first fluid chamber 16. The first fluid chamber 16 is associated with a return mechanism 18a in the form of a spring, which moves the piston 16a after a successful damping stroke back into a position provided for the next damping stroke. The return mechanism 18 a can also be arranged outside the fluid chamber 16. The slide 11 a is preferably integrally connected to the first piston 16 a, so that a movement of the slide 11 a simultaneously leads to a dipping of the first piston 16 a in the first fluid chamber 16. The arranged in the second fluid chamber 21 device 25 for changing the volume in this second fluid chamber 21 comprises in the illustrated embodiment, a displaceable piston 21 a, through which the volume of the second fluid chamber 21 is variable during the inflow or outflow of damping fluid.

By pressing the first piston 16a into the fluid chamber 16, the damping fluid is forced through the channel 19 and through a passage opening 20a of a switching blade 20 into the second fluid chamber 21. The seal 17b seals the piston 21 a from the second fluid chamber 21 a from. By pressing the damping fluid from the first fluid chamber 16 into the second fluid chamber 21 and the second piston 21 a is moved to a rear end position. The damping fluid is located exclusively between the first piston 16 a and the second piston 21 a. It can be seen that the direction of movement A of the first piston 16a is transverse to the direction of movement B of the second piston 21a. The direction of movement A of the first piston 16a includes with the direction of movement B of the second piston 21a an angle α, which is preferably between 70 ° and 110 °. Preferably, the directions of movement A and B of the first piston 16 a and the second piston 21 a run perpendicular to each other. The directions of movement A, B can also be parallel spaced from each other.

Fig. 7b shows the fully inserted into the first fluid chamber 16 first piston 16a, ie that the damping process is already completed. By inserting the piston 16 a into the first fluid chamber 16, the existing in the first fluid chamber 16 damping fluid was pressed through the passage 19, through the passage opening 20 a of the switching blade 20 and through the flow passage 22 a in the second fluid chamber 21, whereupon the second piston 21 a was shifted within the second fluid chamber 21 in the rear end position shown. The size of the passage opening 20a of the switching blade 20 increases with increasing pressurization by the damping fluid, whereby the flow cross-section of the passage opening 20a is increased. The switching blade 20 is preferably made of rubber-elastic material.

In Fig. 7c were the two pistons 16a, 21a partially reset by the two return mechanisms 18a, 18b, so that the piston 16a, 21a again in the direction of Fig. 7a shown standby position. The return mechanism 18b thus moves the second piston 21a back in the opposite direction, wherein the existing in the second fluid chamber 21 damping fluid can flow back through both flow openings 22a and 22b. The switching blade 20 was - starting from the in Fig. 7b shown in a first position (in which the damping fluid flows exclusively through the passage opening 20a in the second fluid chamber 21) in a Fig. 7c shown second position in which the switching blade 20 lifts from the flow openings 22a, 22b, so that during the return stroke, the damping fluid can also flow back around the switching blade 20 in the direction of the first fluid chamber 16. In this way, the damping device 10 can again be moved very quickly into a ready position for the next damping stroke. At the same time, the first piston 16a of the first fluid chamber 16 is also moved back by the return mechanism 18a and can again assume the standby position. It can also be provided that the arrangement of the second return mechanism 18b can be omitted and only the first return mechanism 18a is provided. In this way, upon the return of the first piston 16a, a negative pressure is generated in the first fluid chamber 16, through the coming of the second fluid chamber 21 damping fluid passes through suction again into the first fluid chamber 16. Starting from Fig. 7c are the two pistons 16a, 21 a back in the in Fig. 7a shown starting position zurückbewegbar.

The switching blade 20 thus assumes a triple function, namely a) for pressure build-up of the damping medium in the first fluid chamber 16, b) for overload protection by radial expansion of the passage opening 20, so that the flow cross-section is increased and c) to the damper return by lifting the switching blade 20 of the flow openings 22a and 22b.

According to one embodiment of the invention it is provided that the piston surface of the first piston 16 and the piston surface of the second piston 21 have the same effective piston area. But it is also possible to form the effective piston area of the first piston 16 a and those of the second piston 21 a of different sizes, so that a path reduction of the second piston 21 can be brought about. Thus, if the effective piston area of the second piston 21 is selected larger than the effective piston area of the first piston 16, then a damping stroke of the first piston 16a also leads to a reduced damping stroke of the second piston 21a. Due to the reduced damping stroke of the second piston 21 a, if appropriate, the length of the second fluid chamber 21 and thus the size of the housing 10 a can be reduced.

Fig. 8a shows an alternative embodiment of a damping device 10. Analogous to the embodiment according to the Fig. 7a-7c a slider 11 a is provided, which is integrally connected to the first piston 16 a, so that during the damping stroke of the first piston 16 a is immersed in the first fluid chamber 16. A seal 17a seals the first piston 16a from the first fluid chamber 16. During the damping stroke, the damping fluid displaced by the first piston 16a can flow via the passage opening 20a of the switching disk 20 and through the throughflow opening 22a into the second fluid chamber 21. In the exemplary embodiment shown, the device 25 arranged in the second fluid chamber 21 comprises a compressible, viable piece of material, by means of which the volume of the second fluid chamber 21 can be changed during the inflow or outflow of damping fluid. In Fig. 8a is the first Piston 16a shown in a standby position for the damping stroke. In Fig. 8b For example, by forcing the first piston 16a into the first fluid chamber 16, the damping fluid was forced into the second fluid chamber 25 via the pathways described above, thereby deforming the device 25 and increasing the volume of the second fluid chamber 21. When the slide 11a is no longer acted upon by the articulated lever 7 of the furniture hinge 4, the first piston 16a of the first fluid chamber 16 by the return mechanism 18a back into the in Fig. 8a moved back position shown. As a result, a negative pressure is created in the first fluid chamber 16, whereby the fluid in the second fluid chamber 21 is drawn back through the flow openings 22a, 22b and around the switching blade 20 back into the first fluid chamber 16 by suction, whereupon the device 25 the second fluid chamber 21 expands again and again in Fig. 8a shown position occupies. It is therefore not absolutely necessary, even in the second fluid chamber 21 to provide a displaceable second piston 21 a with its own return mechanism 18 b. The device 25 may comprise a compressible piece of material (eg a TPU plastic part or a sponge rubber). Of course, the device 25 may also include a second piston 21 a as described above, which is slidably mounted within the second fluid chamber 21.

Fig. 9a and Fig. 9b show a possible embodiment, as the furniture hinge 4 also later (ie already ex works or by a user) can be equipped with a damping device 10. In Fig. 9a the body-side stop member 5 and the door-side stop member 6 is shown with the hinge cup 6a, which is pivotally connected via the hinge lever 7 with the body-side stop member 5. The articulated lever 7 is mounted on the hinge cup 6a on the axis of rotation S. On the hinge cup 6a schematically illustrated fastening means 23 (for example in the form of a recess, a locking edge or an opening 23a) are provided, while the housing 10 of the damping device 10 is provided with corresponding fastening means 24 (for example in the form of a resilient locking element 24a).
