Description

Combination of a damping device with hinges for hinging relative to each other articulated furniture parts, in particular on the body of a piece of furniture hinged door leaves or flaps, wherein the hinge has a trained as sunk in a recess of the movable furniture part hinge cup formed stop member which via a hinge mechanism with the carcass Stopping member is pivotally coupled, wherein the damping device comprises a mounted on one of the stopper damper housing, in the cavity of a fluid damping medium and a movable relative to the damping medium resistance element is arranged, which is coupled to a led out of the housing actuator, which at least during a part of Pivoting movement of the two furniture parts relative to each other with the second furniture part is in driving connection and granted him by the second furniture part movement on there s resistance element transmits, wherein the damper housing (62) is arranged on one of the stop parts and the guided out of the damper housing actuator is coupled via at least one connecting member with the other stop member articulated.

Damping devices on the door panels serve to avoid or at least largely reduce the stress and noises arising during the rapid and energetic closure of doors of cabinets in the event of an abrupt deceleration of the door leaf striking the carcass. Such, with gaseous substances, such as For example, atmospheric air or with viscous fluids, such as silicone oil working as damping medium damping devices are known per se. One of these known damping devices (DE 195 22 254 A1) is designed so that the damping effect by compression and throttled blowing the air enclosed in a cylindrical housing by means of a displaceably arranged in the housing piston, the piston rod protrudes with the door open from the cabinet body, so that the door leaf during closing closes at the free end of the piston rod and then slowed down. In another known damping device (AT 004 213 U1) a protruding from the cabinet body elongated displaceable plunger is provided with a toothing, which is connected via a pinion with a rotary damper, which works as silicone oil as a damping medium. When used in furniture, these damping devices are attached separately to the cabinet body, in such a way that the impact shock of the door catching plunger or the piston rod in the opposite region of the hinges of the inside of the door leaf to act. This means, however, that the damping devices are visible when the door is open and projecting parts of the actuators, ie the piston rod or plunger protrude from the cabinet body, so there is a risk that when loading the cabinet with or the removal of storage material, for example Garments, these hang on the parts of the actuator projecting from the body of the furniture and thereby damaged. Even injuries to persons themselves can not be ruled out.

In a so-called four-joint hinge, in which an attachable to the body of a piece of furniture designed as an elongate hinge arm body stop member is coupled via a link formed by two link mechanism with a hinged pot designed as a door stop member, it is known (US-A-5 012 551) to arrange the cylinder of a designed as a hydraulic damping medium piston-cylinder unit damper on the hinge arm, that engages the free end of the guided through an elastically deformable end cap of the cylinder piston rod in the body side bearing portion of the handlebar of the hinge mechanism. As a result of the closely adjacent arrangement of the cylinder at the bearing point of the link in the hinge arm, the piston rod and thus the associated piston perform only a very short damping stroke. The achievable with this known damping arrangement damping effect is therefore limited, especially since the diameter of the damper cylinder is limited due to the given installation conditions in or on the hinge arm.

The invention is based on the object to provide such damping devices for the door of cabinets, in which not only the described possibilities of sticking objects or the injury of persons is avoided by protruding from the inside of the cabinet parts, and the damping device is not visually in Appearance occurs, but which is the realization of stronger damping effect at least in the vicinity of the door leaf to its closed position on the cabinet body feasible.

Starting from a furniture hinge with damping device of the type mentioned above, this object is achieved in a first embodiment of the invention in that the provided on the body-stop member damper housing has at least one circular in cross-section limited, filled with the fluid damping medium cavity, in which the resistance element in Circumferentially rotatably mounted on an at least one side led out from an end side of the damper housing shaft, and that on the led out of the damper housing end of the shaft, the actuating element is arranged in the form of a lever arm, and that at the free end of the lever arm, the one end of the elongated connecting member is hinged, the opposite second end is hinged to the other stop member.

If the hinge is designed as a conventional universal joint hinge, in which one of the universal joint arms at a pointing in the interior interior rear end is coupled by a slotted guide longitudinally displaceable and pivotable with the carcass stop member, wherein the slotted guide of a spaced apart in two parallel side surfaces of the provided as an elongated body body-shaped stop member provided grooves and provided in each of the side surfaces cross parallel side cheeks of Kreuzgelenkarms, engaging in each associated groove pin is formed, the combination of the damper with the hinge in an advantageous embodiment of the invention can be designed in that the damper housing has an elongate cylindrical cavity filled with the fluid damping medium, in which a piston is longitudinally displaceably disposed as a resistance element, on which a engages the actuating element forming the piston rod, the piston remote end is led out of the damper housing, wherein the damping device provided in a centrally between the side surfaces of the body-stop member, at the inside of the body facing end of the carcass part open elongated Cavity is arranged and the part of the slotted guide forming grooves from the side surfaces of the body-stop member to pass into the cavity and that the free end of the piston rod of the damper device is provided on the door leaf-side front end slidable in the damper housing designed as a damping cylinder, wherein the free inner Ends of protruding from the cheeks of the Kreuzgelenkarms through the grooves in the elongated cavity pins with the damping cylinder are in driving connection.

Fig. 6

the embodiment of FIGS. 4 and 5 in an isometric three-dimensional representation in the longitudinal center section in the Fig. 5 corresponding opening position of the door leaf.

In Figures 1 to 3, a first embodiment of the combination of a damping device is schematically shown with a furniture hinge 10, in which a so-called rotary damper 60 is used, in which in a circular cross-section limited, with a viscous-viscous damping medium, such as silicone oil etc .. filled space resistive elements in the form of damper blades, etc. are arranged on a passing through the space filled with the damping medium wave, is led out of the at least one end of the end wall of the space filled with the damping medium space.

In the embodiment shown in Figures 1 to 3 is such - only schematically illustrated - rotary damper 60 arranged on a at the inner core end of the support arm 18 of the hinge 10 and at the same time the housing 62 of the rotary damper forming bearing block, wherein on the protruding from the housing 62 end of the shaft 63 of the rotary damper, a lever arm 64 is rotatably attached, which articulated to an elongated, substantially U-shaped profiled link 66 is connected, the opposite end in turn is hingedly coupled to the hinge cup 24. It can be seen in the figures that in the completely open position of the door leaf 12 (FIG. 1) the lever arm 64 and the connected connecting member 66 are essentially in an extended position. When closing the door leaf 12, the lever arm 64 is pivoted by the then moving towards the interior of the cabinet associated associated end of the connecting member 66 into the cabinet interior, wherein the inside of the filled with silicone oil circular cross-section cavity of the rotary damper 60 resistance elements are pivoted in the same direction. The enclosed in the cavity as a damping medium silicone oil builds up a speed-dependent resistance, which opposes the closing of the door leaf 12 a corresponding resistance, that builds up a closing the door leaf counteracting damping resistance.

It can be seen that the hinge is covered in the fully open position by the described embodiment of the damping device and its coupling to the hinge 10 through the profiled link 66, so that this connecting member 66 thus provides an additional function as anti-trap, which is both the pinching of garment closures in the hinge mechanism as well as unwanted injuries caused by the pinching of fingers in the hinge mechanism of the hinge.

In the second exemplary embodiment shown in FIGS. 4 to 6, the possibility of integrating a damping device 100 designed as a linear damper into a furniture hinge designed as a universal joint hinge 10 'is illustrated.

The universal joint hinge 10 'has an elongated body-stop member 18 mounted on a mounting plate 16 secured to the support wall 14 of the cabinet of a cabinet, which is mounted above the links of a universal joint mechanism with a door panel 24 mounted in a recess in the associated door leaf 12 and designed as a hinge cup 24. Stop part is coupled. The universal joint mechanism is formed by two cross-jointed arms 20 ', 22', which in its central region by a Bearing pin 21 'scissor-like connected to each other pivotally. The angled door-leaf-side end of the cross-jointed arm 20 'is pivotally mounted in the hinge cup 24, while its opposite end body has two laterally spaced parallel cheeks 20a, 20b of the cross-joint arm 20' respectively inwardly projecting pins 25, each in an associated elongated groove 27th engage in the opposite side surfaces of the body-stop member 18. The pins 25 and the grooves 27 thus form a slotted guide for the inner end of the Kreuzgelenkarms 20 ', which thus allows both a pivoting and a longitudinal displacement of this Kreuzgelenkarms relative to the body-stop member 18. The second cross-jointed arm 22 'is pivotably articulated in its supporting-wall-side end region on the door-leaf-side front end of the body-mounting part 18, while its opposite end is coupled to the hinge cup 24 via an interposed link 29. In that regard, the described universal joint hinge 10 'corresponds to known universal joint hinges.

The damping device 100 is arranged in the present case within a cylindrical and open at the inner end open longitudinal bore 31 in the body-stop member 18 and has a fixed end of the longitudinal bore 31 piston rod 38, at the opposite end of a piston 36 is arranged. The piston 36 is slidably disposed in a damper housing designed as a damping cylinder 32, which in turn is in driving connection with the free, inwardly facing ends of the guided in the grooves 27 pins 25. With a displacement of the carcass inner end of the Kreuzgelenkarms 20 'so also the damping cylinder 32 moves relative to the piston 36, wherein a trapped between the piston and the damping cylinder gaseous or other fluid damping medium by throttled passage from the respectively diminishing damper space and the increasing damper space the desired damping effect unfolds. When the door leaf 12 is closed, the largest part of the damping cylinder 32 then projects from the rear open end of the carcass mounting part 18 into the interior of the carcass in the manner shown in FIG. 16. When opening the door leaf 12, it is then increasingly drawn by the sliding in the grooves 27 pins 25 in the longitudinal bore 31.

From the above description of the two embodiments, it is clear that the damping devices according to the invention in their functional design make use of the principles of operation known per se damper. New and advantageous in contrast, that the damping devices are arranged in the hinged by hinges on the body of the associated cabinet edge region of the door, and at or immediately adjacent to the hinges themselves, which has the advantage that they visually hardly appear when the door is open, but as part of the hinges required anyway.
