Description

damping device

The invention relates to a damping device for furniture parts hinged to one another by means of hinges, in particular hinged to the body of a piece of furniture, which has a damper housing which can be attached to one of the furniture parts and in whose cavity a fluid damping medium and a resistance element which is movable relative to the damping medium is arranged , which is coupled to an actuating element which is led out of the housing and which is in driving connection with the second furniture part at least during part of the pivoting movement of the two furniture parts and transmits the movement imparted to it by the second furniture part to the resistance element.

Damping devices on door leaves serve to avoid or at least largely reduce the stresses and noises that arise during the rapid and swinging closing of doors of cupboards during the sudden braking of the door leaf hitting the body. Such damping devices working with gaseous substances, such as atmospheric air or with viscous liquids, such as silicone oil as damping medium, are known per se. One of these known damping devices (DE 195 22 254 A1) is designed so that the damping effect is achieved by compression and throttled blowing off of the air enclosed in a cylindrical housing by means of a piston which is displaceably arranged in the housing and whose piston rod protrudes from the cabinet body when the door leaf is open. so that the door leaf starts at the free end of the piston rod during the closing process and is then braked. In another known damping device (AT 004 213 U1) a protruding from the cabinet body is Hender elongated sliding plunger provided with a toothing, which is connected via a pinion to a rotary damper, which works, for example, silicone oil as a damping medium. When used in furniture construction, these damping devices are attached separately to the cabinet body, in such a way that the plunger that intercepts the impact impact of the door leaf or the piston rod comes into effect in the area of the inside of the door leaf opposite the hinges. However, this means that the damping devices are visible when the door leaf is open and the protruding parts of the actuating elements, i.e. the piston rod or plunger, protrude from the cabinet body, so that there is a risk that, for example, when the cabinet is loaded with or removed from the storage item Items of clothing that stick to the parts of the actuating element protruding from the body of the piece of furniture and are thereby damaged. Injuries to people themselves cannot be ruled out.

The invention is based on the object to provide such damping devices for the door leaves of cabinets, in which the described possibilities of getting stuck to objects or injury to people by parts emerging from the interior of the cabinet is avoided, and the damping device does not appear optically ,

Starting from a damping device of the type mentioned at the outset, this object is achieved according to the invention in that the damping device is arranged in the region of at least one of the hinges which pivotably couple the two furniture parts, and that either the damper housing and / or the actuating element at least during the damping process on one of the Attack parts of the associated hinge attacks. The arrangement of the damping devices) in the area of the hinges articulating the pivotable furniture part on the body ensures that such sticking to the projecting actuating part when the furniture part is open, for. B. an open door is excluded because the immediately adjacent open furniture part protrudes beyond the part of the actuating element protruding from the body.

The configuration can be such that the damper housing has, in a manner known per se, an elongated cylindrical cavity filled with the fluid damping medium, in which a piston is arranged in a longitudinally displaceable manner as a resistance element, on which a piston rod forming the actuating element acts, the end of which faces away from the piston from the damping housing is brought out.

Alternatively, the damping device can also be designed in such a way that the damper housing has at least one cavity with a circular cross-section and filled with the fluid damping medium, in which the resistance element is rotatably mounted in the circumferential direction on a shaft which is guided at least on one side out of an end face of the damper housing, wherein then the actuating element in the form of a lever arm or a gearwheel is arranged on the end of the shaft which is led out of the damper housing.

If the damper housing is arranged on the supporting wall stop part of a furniture hinge designed as an articulated hinge and intended for the pivotable articulation of a door leaf on the associated body of a cabinet, the configuration can take place in such a way that the area of the actuating element lying outside the damper housing is oriented such that it at least during a final part of the door leaf closing movement is in driving connection with the door leaf stop part or a region of the door leaf directly adjoining the door leaf stop part.

The damper housing is then expediently arranged on the upper web wall facing away from the supporting wall of the supporting wall stop part of the furniture hinge designed as an elongated hinge arm, the free end of the actuating element which is led out of the damper housing being aligned with the inside of the door leaf.

At the free end of the piston rod, a buffer can then be provided to reduce the damping impact that occurs when the door leaf closes when it hits the inside of the piston rod. For this purpose, the buffer is expediently designed to be elastically compressible in the direction of the longitudinal axis of the piston rod.

Alternatively, on the part of the piston rod protruding from the damper housing, a cover which is displaceable longitudinally on the damper housing can also be provided, which then takes over the function of the buffer and at the same time covers the piston rod.

To reduce the impact impact when the door wing hits the Covering, it can be advantageous if the cover, which is longitudinally displaceable on the damper housing, is arranged such that it is longitudinally displaceable by a predetermined amount on the end of the piston rod led out of the damper housing and a spring which can be compressed elastically in the direction of the longitudinal central axis of the piston rod is arranged between the piston rod and the cover housing ,

The configuration can be such that the free end of the piston rod is guided in a bore with a light cross section that is complementary to the cross section of the piston rod in a projection that protrudes from the inside of the end wall of the cover to the damper housing, and that the spring acts as a damper housing on one side helical spring is formed on the piston rod and in the opposite end region on the end wall of the cover.

It can then be expedient if the cover is additionally guided and held on the damper housing in a longitudinally displaceable manner by a longitudinal guide. In an advantageous embodiment of the invention, this is achieved in that pins are provided on the damper housing on two diametrically opposite sides of the outer wall, which engage in each case an elongated hole or a groove provided in the inside of the cover. The width of the elongated hole or groove then essentially corresponds to the diameter of the associated pin, while the measure of the maximum possible longitudinal displaceability of the cover relative to the damper housing is set via a corresponding length dimensioning of the elongated hole or groove.

The damper housing can also be arranged on the door leaf stop part of a furniture hinge designed as an articulated hinge and intended for pivotable articulation of the door leaf on the associated body of a cupboard, the area of the actuating element lying outside the damper housing being aligned such that this at least during a final part of the Door leaf closing movement and driving connection with the supporting wall stop part is available.

The damper housing can then be an integral part of the door leaf stop part or - alternatively - also be a separate component which can be mounted on the door leaf directly after the door leaf stop part. An embodiment has proven to be particularly advantageous in which the damper housing has two spaced-apart cavities filled with fluid damping medium, a gearwheel being arranged on the ends of the shafts which support the resistance elements so as to be rotatable in the cavities, each having a gearwheel comb a toothing provided on opposite longitudinal edges of one with its free end during a final part of the closing movement of the door leaf with one of the hinge stop parts in a driving connection slider.

If the hinge to be damped is designed as a universal joint hinge, in which one of the universal joint arms at its rear end pointing into the interior of the body is coupled to the supporting wall stop part so as to be longitudinally displaceably pivotable by means of a link guide, the link guide being in each case in two spaced-apart parallel side faces of the as elongated Body-formed supporting wall stop part provided grooves and a respective provided from the side surfaces overlapping parallel side cheeks of the universal joint arm, which engages in the respectively assigned groove, the damping device can advantageously be provided in a center between the side surfaces of the supporting arm stop part, on which be arranged in the body-facing end of the bulkhead stop part open elongated cavity, the part of the slide guide forming groove then from the side surfaces of the bulkhead stop part ls go through into this cavity. This makes a configuration possible in which the free end of the piston rod of the damping device is attached to the front end of the elongated cavity on the door wing side and is provided on the opposite end of the damper housing, which is slidably mounted in the damping cylinder, the free inner ends of the cheeks of the universal joint arm can be brought into driving connection with the damping cylinder by the grooves protruding into the elongated cavity. This entrainment connection can be designed, for example, as a bayonet connection, in which the free ends of the pins can be inserted into correspondingly shaped receptacles in the damping cylinder and then locked by rotation.

The invention is explained in more detail in the following description of several exemplary embodiments in conjunction with the drawing, specifically showing or showing:

Articulation of a door leaf on the supporting wall of a cabinet body provided universal joint hinge, which is provided as a sixth embodiment with a damping device according to the invention, the door leaf being shown in the closed position;

FIG. 17 shows the exemplary embodiment shown in FIG. 16, the partially open position of the door leaf being shown; and

18 shows the universal joint hinge according to FIGS. 16 and 17 in an isometric three-dimensional representation in a longitudinal central section in the open position of the door leaf corresponding to FIG. 17. 1 and 2 show a furniture hinge, designated in its entirety by 10 and designed as a four-joint hinge, by means of which a door leaf 12 is pivotably articulated on the supporting wall 14 of the body of a cabinet. The hinge 10 is designed as a four-bar hinge known per se, in which a support arm 18, which is adjustably attachable to a mounting plate 16 fastened to the mounting wall 14, is coupled via two hinge links 20 and 22 to a hinge cup 24 which can be countersunk in a recess in the door leaf 12.

On the support arm 18, a damping device 30 is attached, which has a damper housing 32, in which an elongated cylindrical cavity 34 is formed, in which a piston 36 is arranged to be longitudinally displaceable, on the end face of which faces the door leaf 12, a piston rod 38 is attached, which seals is passed through a stopper 40 which closes the cavity 34 and carries at its free end a buffer 42 which, when the door leaf is open (FIG. 1), projects somewhat beyond the front end edge 44 of the supporting wall. When the opened door leaf 12 is closed, the inside of the door then runs against the buffer 42 before reaching the closed position (FIG. 2) and, when it is closed further, moves the piston 36 in the cavity 34 into the position shown in FIG. 2 via the piston rod 38. The cavity 34 is filled with a damping medium in the form of a damping liquid or a damping gas, so that the piston 36 can only be closed against a resistance force which is also dependent on the displacement speed and which - via the piston rod 38 and the buffer 42 - the closing movement of the door leaf 12 dampens, so that a jerky and associated with an impact noise closing the door leaf 12 is avoided.

When the door leaf 12 is subsequently opened, the inner surface of the door leaf lifts off the buffer 42, so that there is no opening resistance. The piston is designed by means of appropriately calibrated throttle openings, which may be provided with check valves, in such a way that it only offers very little resistance to displacement in the cavity 34 in the direction of the door leaf, so that it can be pushed back into the starting position by a relatively weak spring 48.

FIGS. 3 to 5 describe a damping device 50 which is fundamentally similar to the damping device 30 described above in connection with FIGS. 1 and 2, but which differs from the damping device 30 only in that the buffer 42 forms a cover housing 52 for the damping device - Fergehäuse 32 protruding piston rod 38 is redesigned. Since the structure and function of the damping device 50 otherwise completely corresponds to the previously described damping device 30 and otherwise identical components of the damping devices as well as the hinge shown and its parts are designated by the same reference numerals in the drawing figures, reference can be made to the above description in this regard ,

The hinge 10 shown in FIGS. 6 and 7 has a damping device 30 which is functionally identical to the damping device 30 described above in connection with FIGS. 3 to 5 of the second exemplary embodiment, but in which the end of the piston rod 38 facing the door wing is not rigidly fastened to the cover 52 is. The reduced-diameter outer free end of the piston rod 38 is rather mounted in a longitudinally displaceable manner in a bore which is formed in a projection 43 which projects from the inside of the end wall of the cover 52 to the damper housing 32. A helical spring 39 supported on the inside of the end wall of the cover 52 on the one hand and a disk 41 arranged on the piston rod 38 on the other hand holds the free end of the piston rod 38 in the non-compressed state in the projection shown in FIGS. 6 and 7, partly from the bore 43 extended position. When the door leaf 12 closes with force from the closing direction illustrated by the arrow s in FIG. 6, the inside of the door leaf 12 strikes the outside of the end wall of the cover 52 when the closed position is approached. The resulting shock is not transmitted directly into the piston rod 38, but initially results in a displacement of the piston rod into the interior of the bore in the projection 43, the helical spring 39 being compressed at the same time. As a result, the impact stress is reduced and converted into a compressive prestress of the coil spring 39. This compressive bias is then transferred to the piston rod 38 again in the final closing process with the coil spring 39 relaxed. As a result, an impact damping generated by the elastic buffer 42 in the exemplary embodiment according to FIGS. 1 and 2 is realized to an even greater extent.

In order to prevent the door wing 12 from separating or jumping off from the damper housing 32 as a result of the impact of the door leaf 12, two short pins 33 appearing diametrically from the outer wall thereof are provided on the damper housing 32, each in an assigned groove 53 in the opposite one Engage the wall of the cover 52. Pins 33 and grooves 53 thus form longitudinal guides, which have a predetermined longitudinal displacement of cover 32 allow relative to the damper housing 52, but prevent the cover from lifting off from the damper housing by positive engagement of the respective pin 33 in the associated groove 53.

A further exemplary embodiment of a damping device for furniture hinges is shown schematically in FIGS. 8 to 10, in which a damping principle which differs functionally from the damping devices used in the above exemplary embodiments is used. A so-called rotary damper is used, in which resistance elements in the form of damper vanes etc. are arranged in a space with a circular cross-section and filled with a viscous damping medium, such as silicone oil, etc., on a shaft penetrating the space filled with the damping medium, at least one end of which is led out of the end wall of the space filled with the damping medium.

In the exemplary embodiment shown in FIGS. 8 to 10, such a rotary damper 60, which is only shown schematically, is arranged on a bearing block 62 which is arranged on the inner end of the support arm 18 of the hinge 10 and at the same time forms the housing of the rotary damper protruding end of the shaft 63 of the rotary damper, a lever arm 64 is fastened in a rotationally fixed manner, which is articulatedly connected to an elongated, essentially U-shaped profiled connecting member 66, the opposite end of which in turn is articulated to the hinge cup 24. It can be seen in the figures that in the fully open position of the door leaf 12 (FIG. 6) the lever arm 64 and the connected connecting member 66 are essentially in an extended position. When the door leaf 12 is closed, the lever arm 64 is pivoted into the interior of the cabinet by the connected end of the connecting member 66 which then migrates in the direction of the interior of the associated cabinet, the resistance elements located in the interior of the circular cross-sectional cavity of the rotary damper filled with silicone oil being pivoted in the same direction. The silicone oil enclosed in the cavity as a damping medium builds up a speed-dependent resistance force which opposes the closing of the door leaf 12, i.e. builds up a damping resistance counteracting the closing of the door leaf.

It can be seen that the described design of the damping device and its coupling to the hinge 10 by the profiled connecting member 66 the hinge is covered in the fully open position, so that this connecting member 66 therefore offers an additional function as a pinch protection, which prevents both items of clothing in the cabinet from being pinched in the hinge mechanism and unwanted injuries by pinching fingers in the hinge area.

FIGS. 11 and 12 show a fourth exemplary embodiment of a damping device 70 according to the invention, which in turn corresponds functionally to the damping devices described in connection with FIGS. 1 and 2 and 3 to 5, but in this case the damper housing 32 is attached on the door wing side as an integral part of the hinge housing 24 Part is formed. In this case, the end of the piston rod 38 protruding from the housing 32 carries, instead of the buffer 42 of the damping device 30, a wheel 72 which rolls on the upper web surface of the support arm 18 of the hinge 10 and thereby prevents frictional wear and is rotatably mounted on the end of the piston rod.

The fifth exemplary embodiment of a damping device 80 shown in FIGS. 13 to 15 is - insofar as in accordance with the damping device 70 described above - also arranged on the door leaf side, directly after the fastening flange 82 of the hinge cup 24 resting on the rear side of the door leaf 12. The damping device 80 has a flat damper housing 82, which is covered by a cover 84 on the top. In the damper housing 82, a slide 86 is guided so as to be longitudinally displaceable in a recess on the hinge cup side, from which an extension 88 extends at the end remote from the hinge cup into a suitable elongated recess 90 of the damping housing 82. The two opposite longitudinal edges of the extension 88 are each provided with a rack-like toothing 92 which mesh with gear wheels 94 rotatably mounted in the damper housing 82. In turn, below the gear wheels 94, rotary dampers - not shown - are arranged in the damper housing 82, which are non-rotatably connected to the gear wheels 94. When the slide 86 is displaced in the housing 82, the gear wheels 94 are also set in rotation via the toothing 92, the damping force then being built up again in the two rotary dampers coupled to the gear wheels. It can be seen in FIGS. 11 and 12 that the slide 86 is displaced when the door leaf 12 closes before the door leaf closed position is reached, with a roller 96 rotatably arranged on the free end of the slide 86 on the hinge cup side on the upper web surface of the support arm 18 of the hinge 10 starts. The The slide 86 is returned when the door leaf 12 is opened again by a compression spring 98 supported on the slide 86 on the one hand and the recess 90 on the other hand.

In the exemplary embodiment shown in FIGS. 16 to 18, the possibility of integrating a damping device 100 into a furniture hinge designed as a universal joint hinge 10 ′ is illustrated.

The universal joint hinge 10 ′ has an elongated supporting wall stop part 18, which is mounted on a mounting plate 16 fastened to the supporting wall 14 of the body of a cabinet and which, via the links of a universal joint mechanism, has a door leaf designed as a hinge cup 24 and mounted in a recess in the associated door leaf 12. Stop part is coupled. The universal joint mechanism is formed by two universal joint arms 20 ', 22', which in their central region are connected to one another in a scissor-like manner by means of a bearing pin 21 '. The angled end of the universal joint arm 20 'on the door wing side is pivotally mounted in the hinge cup 24, while its opposite inner end of the body has two pins 25, each projecting inward from laterally spaced parallel cheeks 20a, 20b of the universal joint arm 20', each in an assigned elongated groove 27 in engage the opposite side surfaces of the support wall stop member 18. The pins 25 and the grooves 27 thus form a link guide for the inner end of the universal joint arm 20 ', which thus enables both pivoting and longitudinal displacement of this universal joint arm relative to the supporting wall stop part 18. The second universal joint arm 22 'is pivotally articulated in its end region on the supporting wall side at the front end of the supporting wall stop part 18 on the door leaf side, while its opposite end is coupled to the hinge cup 24 via an intermediate link 29. In this respect, the universal joint hinge 10 ′ described corresponds to known universal joint hinges.

In the present case, the damping device 100 is arranged within a cylindrical longitudinal bore 31 that opens at the inner end of the body in the supporting wall stop part 18 and has a piston rod 38 attached to the closed end of the longitudinal bore 31, on the opposite end of which a piston 36 is arranged. The piston 36 is displaceably arranged in a damper housing designed as a damping cylinder 32, which in turn engages in connection with the free, inward-facing ends of the pins 25 guided in the grooves 27. manure stands. When the inner end of the universal joint arm 20 'is shifted, the damping cylinder 32 also shifts relative to the piston 36, a gaseous or other fluid damping medium enclosed between the piston and the damping cylinder being throttled by passage from the respectively reducing damper space and the enlarging damper space the desired damping effect unfolds. When the door leaf 12 is closed, the largest part of the damping cylinder 32 then protrudes from the rear open end of the supporting wall stop part 18 into the interior of the body in the manner shown in FIG. 16. When the door leaf 12 is opened, it is then increasingly drawn into the longitudinal bore 31 by the pins 25 which move in the grooves 27.

It is clear from the above description of the various exemplary embodiments that the damping devices according to the invention, in their functional design, make use of the functional principles of dampers known per se. In contrast, it is new and advantageous that the damping devices are arranged in the edge region of the door wing, which is hinged to the body of the associated cabinet, at or immediately afterwards on the hinges themselves, which has the advantage that they hardly appear visually when the door wing is open occur, but are regarded as part of the hinges that are required anyway.
