Thus, as shown in FIGS. 1 and 2, the first fitment portion 5 has a base plate 5a and at least one leg 5b extending perpendicularly from the base plate 5a. It will be appreciated that the fitment portion 5 may also be in the form of a hinge arm. The second fitment portion 6 has a hinge cup 6a which can be sunk in a bore on the movable furniture part 3. The hinge cup 6a has a flange 6b which in the mounted position bears against the inside of the movable furniture part 3. Arranged between the fitment portion 5 and the hinge cup 6a is a hinge lever 7 which is mounted displaceably and/or tiltably relative to the first fitment portion 5 by way of an adjusting device 8. The hinge lever 7 is mounted pivotably to the hinge cup 6a at an axis of rotation on the other side. In the illustrated embodiment therefore the furniture hinge 4 is in the form of a single-axis hinge. It is possible to see a spring device 9 which urges the two fitment portions 5, 6 in the direction of the closed position or holds the fitment portions 5, 6 in a closed position. A damping device 10 is arranged substantially completely within the hinge cup 6a, wherein the damping device 10 is provided for damping a relative movement of the two fitment portions 5, 6 relative to each other over a part of the movement through the maximum opening angle of the two fitment portions 5, 6. The damping device 10 has an actuating element 11 in the form of a linearly displaceable slider 11a which is acted upon by the hinge lever 7 towards the end of the closing movement of the furniture hinge 6 and thereby applies the force to the damping device 10.

FIG. 3a shows a side view of the open furniture hinge 4 in the mounted condition. The first fitment portion 5 is fixed to the frame 2a of the furniture carcass 2 while the second fitment portion 6 is mounted with the hinge cup 6a to the movable furniture part 3. It is possible to see the damping device 10 whose arcuate peripheral edge is at least partially adapted to the contour of the inside wall of the hinge cup 6a. The housing of the damping device 10 can be for example at least approximately of a mushroom-shaped configuration in plan view. The hinge lever 7 which is pivoted during the hinge movement acts on the linearly displaceable slider 11a towards the end of the closing movement whereby the damping process is initiated. The Figure also shows the spring device 9 which in the illustrated embodiment performs the function of at closing spring.

FIG. 3b shows a vertical section along the arrows shown in FIG. 3a. The carcass fitment portion 5 is fixed to the frame 2a by way of a screw 12. The hinge cup 6a is sunk in the movable furniture part 3, the damping device 10 with the slider 11a being completely integrated in the hinge cup 6a. The slider 11a has an inclined surface 15 which is acted upon by the hinge lever 7 as from a predetermined relative position of the fitment portions 5 and 6 with respect to each other. The slider 11a has a slot 13 so that the slider 11a is displaceable guidedly during the damping process relative to a fixing projection 14 arranged stationarily on the hinge cup. In the illustrated Figure the hinge lever 7 is in a position of being spaced from the inclined surface 15 of the slider 11a.

FIG. 4a shows a view similar to FIG. 3a, with the difference that the movable furniture part 3 has been further moved in the closing direction and the hinge lever 7 now encounters the slider 11a of the damping device 10, which can be particularly clearly seen from the sectional view in FIG. 4b. The cranked hinge lever 7 now abuts against the inclined surface 15 of the slider 11a whereby the damping process is initiated.

FIG. 5a shows the completely closed position of the movable furniture part 3 relative to the frame 2a, the damping process already being concluded. It can be seen from the sectional view in FIG. 5b that the hinge lever 7 has displaced the slider 11a by way of the inclined surface 15 thereof so that the stationary fixing projection 14, in comparison with FIG. 4b, bears against the opposite end of the slot 13. The movement to be damped has been applied to the damping device 14 by the movement of the slider 11a.

FIG. 6 shows the damping device 10 which can be completely integrated into the hinge cup 6a and the housing 10a of which is at least portion-wise adapted to the inside shape of the hinge cup 6a. The housing 10a has an arcuate peripheral edge which in the mounted position bears at least region-wise against the inside wall of the hinge cup 6a. The slider 11a with its inclined surface 15 and its slot 13 is mounted displaceably relative to the housing 10a during the damping stroke and during the return stroke.

FIG. 7a shows a perspective view in horizontal section of the damping device 10, with reference to which the operating principle of the damping device 10 is to be described. The Figure shows a first fluid chamber 16 in which a first piston 16a is linearly displaceably guided. The damping device 10 is in the form of a fluid damper, the first fluid chamber 16 being filled with a damping fluid (for example a liquid, an oil or, with a suitable structural size, also with air). A seal 17a seals the first piston 16a with respect to the inside wall of the first fluid chamber 16. Associated with the first fluid chamber 16 is a return mechanism 18a in the form of a spring which, after the damping stroke has been effected, moves the piston 16a back into a position for the next damping stroke again. The return mechanism 18a can also be arranged outside the fluid chamber 16. The slider 11a is preferably integrally connected to the first piston 16a so that a movement of the slider 11a at the same time also leads to movement of the first piston 16a into the first fluid chamber 16. The device 25 arranged in the second fluid chamber 21 for altering the volume in that second fluid chamber, in the illustrated embodiment, includes a displaceable piston 21a, by which the volume of the second chamber 21 can be changed when damping fluid flows in or out.

The damping fluid is pressed through the passage 19 and through a through opening 20a in a switching blade 20 into the second fluid chamber 21 by the first piston 16a being pushed into the fluid chamber 16. The seal 17b seals the piston 21a with respect to the second fluid chamber 21a. The second piston 21a is also displaced into a rearward end position by the damping fluid being pressed from the first fluid chamber 16 into the second fluid chamber 21. The damping fluid is exclusively between the first piston 16a and the second piston 21a. It can be seen that the direction of movement A of the first piston 16a extends transversely relative to the direction of movement B of the second piston 21a. The direction of movement A of the first piston 16a includes an angle α which is preferably between 70° and 110° with the direction of movement B of the second piston 21a. Preferably the directions of movement A and B of time first piston 16a and the second piston 21a are at a right angle to each other. The directions of movement A, B can also extend in mutually parallel spaced relationship.

FIG. 7b shows the first piston 16a pushed completely into the first fluid chamber 16, that is to say the damping process is already concluded. The fact that the piston 16a was pushed into the first fluid chamber 16 provided that the damping fluid in the first fluid chamber 16 was pressed through the passage 19, the opening 20a in the switching blade 20 and the through-flow opening 22a into the second fluid chamber 21, whereupon the second piston 21a was displaced within the second fluid chamber 21 into the rearward end position shown. The size of the through opening 20a in the switching blade 20 increases with increasing pressure actuation by the damping fluid, whereby the flow cross-section of the through opening 20a can be increased. The switching blade 20 is preferably made from rubber-elastic material.

In FIG. 7c the two pistons 16a, 21a have been partially returned main by the two return mechanisms 18a, 18b so that the pistons 16a, 21a are moved in the direction of the readiness position shown in FIG. 7a again. The return mechanism 18b therefore moves the second piston 21a in the opposite direction again, in which case the damping fluid in the second fluid chamber 21 can flow back through the two through-flow openings 21a and 21b. Starting from the first position shown in FIG. 7b (in which the damping fluid flows exclusively through the through opening 20a into the second fluid chamber 21) the switching blade 20 was moved into a second position as shown in FIG. 7c in which the switching blade 20 lifts off the through-flow openings 22a, 22b so that, in 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 that way the damping device 10 can be very quickly moved into a readiness position for the next damping stroke again. 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 readiness 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 that way the return movement of the first piston 16a results in a reduced pressure being produced in the first fluid chamber 16, by which the damping fluid coming from the second fluid chamber 21 due to a suction effect passes into the first fluid chamber 16 again. Starting from FIG. 7c the two pistons 16a, 21a can again be moved back into the starting position shown in FIG. 7a.

The switching blade 20 therefore performs a triple function, more specifically a) for building up the pressure of the damping medium in the first fluid chamber 16, b) overload safeguard by radial expansion of the through opening 20 so that the flow cross-section can be increased, and c) damping return by lifting the switching blade 20 off the through-flow openings 22a and 22b.

In an embodiment of the invention it is provided that the piston surface of the first piston 60 and the piston surface of the second piston 21 have an operative piston surface of the same size. It is however also possible for the effective piston surface of the first piston 16a and that of the second piston 21a to be of differing sizes so that it is possible to provide a travel step-down effect in respect of the second piston 21. When therefore the effective piston surface of the second piston 21 is larger than that of the first piston 16, a damping stroke of the first piston 16a also leads to a reduced damping stroke of the second piston 21a. The length of the second fluid chamber 21 and thus the size of the housing 10a can possibly also be reduced by virtue of the reduced damping stroke of the second piston 21a.

FIG. 8a shows an alternative embodiment of a damping device 10. Similarly to the embodiment of FIGS. 7a-7c, there is provided a slider 11a which is integrally connected to the first piston 16a so that the first piston 16a engages into the first fluid chamber 16 in the damping stroke. A seal 17a seals off the first piston 16a relative to the first fluid chamber 16. In the damping stroke the damping fluid displaced by the first piston 16a con flow by way of the through opening 20a in the switching blade 20 and through the through-flow opening 22a into the second fluid chamber 21. In the illustrated embodiment the device 25 arranged in the second fluid chamber 21 includes a compressible deformable material portion, by which the volume of the second fluid chamber 21 can be altered when damping fluid flows in or out. FIG. 8a shows the first piston 16a in a readiness position for the damping stroke. In FIG. 8b the fact of the first piston 16a being pushed into the first fluid chamber 16 provided that the damping fluid was urged into the second fluid chamber 25 by way of the above-described common paths, whereby the device 25 was deformed and the volume of the second fluid chamber 21 increased. When the slider 11a is no longer acted upon by the hinge lever 17 of the furniture hinge 4 then the first piston 16a of the first fluid chamber 16 is moved back into the position shown in FIG. 8a again by the return mechanism 18a. As a result, a reduced pressure is produced in the first fluid chamber 16, whereby the suction effect causes the fluid in the second fluid chamber 21 to be drawn back through the through-flow openings 22a, 22b and around the switching blade 20 into the first fluid chamber 16 again, whereupon the device 25 of the second fluid chamber 21 also expands again and again assumes the FIG. 8a position. It is therefore not absolutely necessary for a displaceable second piston 21a having its own return mechanism 18b also to be provided in the second fluid chamber 21. The device 25 can have a compressible material portion (for example a TPU plastic portion or a foam rubber). It will be appreciated that the device 25 can also include a second piston 21a as described hereinbefore, which is supported displaceably within the second fluid chamber 21.

FIGS. 9a and 9b show a possible embodiment illustrating how the furniture hinge 4 can also be fitted with a damping device 10 subsequently (that is to say retro-fitted either at the factory or also by a user). FIG. 9a shows the carcass fitment portion 5 and the door fitment portion 6 with the hinge cup 6a connected pivotably to the carcass fitment portion 5 by way of the hinge lever 7. The hinge lever 7 is mounted to the hinge cup 6a at the axis of rotation S. Provided on the hinge cup 6a are diagrammatically shown fixing means 23 (for example in the form of a recess, a latching edge or an opening 23a) while the housing 10a of the damping device 10 is provided with corresponding fixing means 24 (for example in the form of a resilient arresting element 24a). The housing 10a of the damping device 10 can therefore be releasably connected to the hinge cup in the illustrated mounting position by way of the first and second fixing means 23, 24, preferably being automatically latchable.

FIG. 9b shows the damping device 10 with the housing 10a and the slider 11a displaceable relative thereto. For fixing to the furniture hinge 4 the housing 10a has fixing means 24 with at least one arresting element 24a which is in engagement in the mounted position with the opening 23a, shown in FIG. 9a, of the hinge cup 6a. In that way the housing 10a of the damping device 10 can be fixed relative to the hinge cup 6a. In contrast to the slot 13 shown in FIG. 6 the slot 13 in FIG. 9b is open downwardly in order thereby to fit the slider 11a and therewith the damping device 10 subsequently to the fixing projection 14 shown in FIGS. 3b, 4b and 5b respectively. In the mounted condition of the housing 10a the arcuate peripheral surface thereof bears against the inside wall of the hinge cup 6a and does not project beyond the hinge cup 6a. The arresting element 24a is resilient, is acted upon by a spring or is formed directly by a spring and can be moved from the mounted position on the hinge cup 6a into a release position by applying pressure in opposition to the spring force of the arresting element 24a so that the housing 10a of the damping device 10 can be removed again from the hinge cup 6a. The fixing means 24 with the arresting element 24a and the opening 23a on or in the hinge cup 6a is only shown by way of example, it will be appreciated that other possible forms of mounting and removal are also possible. In a kinematic reversal it is also possible for the resilient arresting element to be arranged on the hinge cup 6a and for the opening 23a or latching edge also to be arranged on the housing 10a of the damping device 10.

FIG. 10a shows a further possible way of fixing a damping device 10 which can be arranged in the mounted position entirely within a hinge cup 6a. The damping device 10 includes a housing 10a which can be fitted into the hinge cup 6a from above (therefore substantially at a right angle to the bottom of the hinge cup). The housing 10a of the damping device 10 has a first fixing means 24 in the form of a clip-like or circlip-like spring while the hinge cup 6a is provided with second fixing means 23 in the form of an elongate recess 23a, wherein the housing 10a of the damping device 10 and the hinge cup 6a can be releasably connected together in the mounted position by way of the first and second fixing means 23, 24. It is also possible to see a fixing projection 14 arranged within the hinge cup 6a and extending substantially parallel to an axis of rotation S of the furniture hinge 4. In the interior of the hinge cup 6a the fixing protection 14 has a recess 40 provided for receiving and guiding the linearly displaceable slider 11a. The flattening afforded by the recess 40, or the lower position of the fixing projection 14, permits an enlarged structural space for the housing 10a of the damping device 10.

FIG. 10b shows the mounted position of the damping device 10 within the hinge cup 6a. In that position the damping device 10 does not project beyond the plane of the opening of the hinge cup 6a. The housing 10a has a shoulder-shaped abutment 25a which in the mounted position is supported against a corresponding counterpart abutment 25b of the hinge cup 6a. The peripheral surface of the damping device 10 is adapted to the contour of the internal space in the hinge cup 6a. Towards the end of the closing movement of the movable furniture part 3 relative to the stationary furniture carcass 2 the hinge lever 7 bears against the slider 11a of the damping device 10, whereby the damping process is initiated.

FIG. 11a shows a possible way of removing the damping device 10 fixed in the hinge cup 6a. The housing 10a of the damping device 10 has at least one release portion 26, by which the connection between the first and second fixing means 23, 24 is releasable so that the housing 10a can be completely removed. The housing 10a can be levered out of the hinge cup 6a by applying a screwdriver 27 to the release portion 26 and the carcass abutment portion 5. Removal is of relevance in that respect as a damping effect for the mobile hinge 4 is sometimes not wanted at all. If for example the movable furniture part 3 is pivotably mounted to the furniture carcass 2 by way of a plurality of furniture hinges 4, it may be sufficient for only one furniture hinge 4 to be fitted with a damping device 10, while the other furniture hinges 4 do not have any damping device in order thereby to ensure reliable closure of lighter movable furniture parts 3. FIG. 11b shows a perspective view from the front of the damping device 10, from which it is possible to see the housing 10a with the shoulder-shaped abutment 25a and the linearly displaceable slider 11a. In the illustrated embodiment the release portion 26 for dismantling of the damping device 10 is provided in one piece on the housing 10a. FIG. 11c shows a perspective view than the front of the damping device 10 while FIG. 11d shows a perspective view from the front of the damping device 10.

FIG. 12a shows a further possible way of dismantling the damping device 10 by means of a slot-type screwdriver 27 which in the illustrated embodiment can engage the linearly displaceable slider 11a. Various configurations of the release portion 26 are shown in FIGS. 12 through 12d. In FIG. 12b the release portion 26 is in the form of a bar projecting upwardly from the housing 10a. In FIG. 12c the release portion 26 is in the form of a recess in the displaceable slider 11a, the release portion 26 being adapted to receive a cross-head screwdriver. In FIG. 12d the release portion 26 is also provided on the slider 11a and the release portion 26 with the slider 11a jointly provide a slot-shaped recess in which a slot-type screwdriver can engage for dismantling of the damping device 10.

FIG. 13 shows a highly diagrammatic view of a hinge cup 6a sunk in a provided standard bore 30 in the movable furniture part 3. The hinge cup 6a has a bottom 31 and a side wall 29 extending therearound. The damping device 10 with the housing 10a and the linearly displaceable slider 11a includes first fixing means 24 while second fixing means 23 are associated with the hinge cup 6a, wherein the housing 10a of the damping device 10 can be releasably connected together in the intended mounted position by way of the first and second fixing means 23, 24. The second fixing means 24 of the housing 10a can therefore be releasably connected to the bottom 31 of the hinge cup 6a and/or to a side wall 29 thereof. The hinge lever 7 mounted at the axis of rotation S acts on the linearly displaceable slider 11a as from a predetermined relative position of the hinge cup 6a whereby the slider is pushed into the housing 10a and initiates the damping process.

FIG. 14a shows a perspective view of the furniture hinge 4, wherein the fitment portion 5 in the form of the hinge arm is hingedly connected to the hinge cup 6a by way of at least one hinge lever 7. The housing 10a of the damping device 10 can be fitted into the hinge cup 6a from above when the hinge levers 7 and the hinge arm 5 are mounted, and can be releasably fixed therein. The damping device 10 has a slider 11a movable relative to the housing 10a, wherein the first fixing means 24 are provided on the slider 11a so that the housing 10a of the damping device 10 can be releasably connected to the hinge cup 6a indirectly by way of the slider 11a. In the illustrated Figure the second fixing means 23 of the hinge cup 6a are formed by a fixing projection 14 which projects laterally inwardly from an inside wall of the hinge cup 6a and is provided for connection to the slider 11a. The fixing projection 14 can pass through the side wall of the hinge cup 6a and in so doing also serve to receive the spring device 9, by which the furniture hinge 4 is movable into the completely closed position.

FIG. 14b shows the damping device 10 when subsequently fitted into the hinge cup 6a. The housing 10a of the damping device 10 has an arcuate peripheral edge adapted to the inside shape of the hinge cup 6a. The housing 10a of the damping device 10 has at least one preferably shoulder-shaped abutment 25a which is additionally supported at an inside wall of the hinge cup 6a so that the housing 10a is held at least partially in positively locking relationship within the hinge cup 6a. Towards the end of the closing movement of the hinge 4 the hinge lever 7 encounters the slider 11a, whereupon it is pushed into the housing 10a and the closing movement of the hinge 4 is thus damped.

FIG. 14c shows a highly diagrammatic perspective view of a possible embodiment of a slider 11a. The slider 11a is provided with an inclined surface 15 provided for contact with the hinge lever 7. The first fixing means 24 arranged on the slider 11a include at least one guide groove 43, extending in the longitudinal direction of slider, for the second fixing means 23 arranged on the hinge cup 6a, preferably for the fixing projection 14 arranged in the hinge cup 6a (see FIG. 14a) for fixing the slider 11a. In addition there is an introduction opening 41, through which the fixing projection 14 can be arranged in the guide groove 43. The slider 11a can thus be moved relative to the fixing projection 14 in such a way that the fixing projection 14 can be passed through the introduction opening 41 and positioned in the guide groove 43. In the damping stroke therefore the slider 11a can be displaced relative to the fixing projection 14 mounted in the guide groove 43. To remove the damping device 10 the fixing projection 14 is again threaded through the introduction opening so that the housing 10 can again be moved out of the hinge cup 6a. In the illustrated embodiment the slider 11a has on both longitudinal sides guide grooves 43 provided for receiving two fixing projections 14 disposed in mutually opposite relationship in the hinge cup 6a.

The present invention is not limited to the illustrated embodiments but includes or extends to all variants and technical equivalents which can fall within the scope of the appended claims. The positional references adopted in the description such as for example up, down, lateral and so forth are also related to the directly described and illustrated Figure and are to be appropriately transferred to the new position upon a change in position.
