Aufgabe der vorliegenden Erfindung ist es, eine Bremseinrichtung resp. Dämpfungssystem bereitzustellen, welches beispielsweise in Möbel-, Türscharniere und dergleichen integriert werden kann. Ein weiteres Ziel ist es, eine mechanische Bremseinrichtung bereitzustellen, welche kostengünstig herstellbar ist. Noch ein Ziel ist es, eine Bremseinrichtung vorzuschlagen, welche praktisch unsichtbar in herkömmliche Scharniere integriert werden kann.Object of the present invention is, respectively, a braking device.

Weiterbildungen der Erfindung sind jeweils in den Unteransprüchen angegeben.The object is achieved by a damping device according to claim 1, a hinge according to
Bei der Dämpfungseinrichtung ist einerseits zwischen der Achse und der Achsaufnahme eine mechanische Kopplung (beispielsweise eine Mitnehmereinrichtung) vorgesehen, und andererseits sind die Hülse und die Achse derart ausgebildet, dass bei einer Relativverdrehung der beiden Teile mindestens durch Reibung eine Bremswirkung erzielt ist. Diese Dämpfungseinrichtung hat den Vorteil, dass sich diese beispielsweise in bestehende Scharniere integrieren lässt. Da die Dämpfungseinrichtung sehr klein ausgeführt werden kann, kann die Gestalt der Scharniere im Wesentlichen dieselbe bleiben (Bohrbildkompatibilität). Dies bedeutet, dass für die Montage eines erfindungsgemäss modifizierten Scharniers keine Extrabohrungen nötig sind und daher kein zusätzlicher Arbeitsaufwand anfällt Vom Gestalterischen her ist besonders vorteilhaft, dass die Dämpfungseinrichtung praktisch nicht sichtbar ist.In the damping device on the one hand between the axle and the axle a mechanical coupling (for example, a driver) is provided, and on the other hand, the sleeve and the axle are designed such that at a relative rotation of the two parts at least by friction, a braking effect is achieved. This damping device has the advantage that it can be integrated, for example, in existing hinges. Since the damping device can be made very small, the shape of the hinges can remain substantially the same (Bohrbildkompatibilität). This means that no extra drilling is required for the assembly of a modified hinge according to the invention and therefore no additional work is required From the point of view of design is particularly advantageous that the damping device is practically not visible.
Die Achse und die Achsaufnahme sind derart ausgebildet, dass ein begrenzter Freilauf zwischen der Achse und dem zweiten Teil ermöglicht ist. Dies ermöglicht es, dass die Bremswirkung erst kurz vor der Schliessstellung eintritt.The axle and the axle receptacle are designed such that a limited freewheel between the axle and the second part is made possible. This makes it possible that the braking effect occurs shortly before the closed position.
Vorteilhaft sind die miteinander zusammenwirkenden, als Bremsflächen dienenden Oberflächen der Hülse und der Achse nicht rotationssymmetrisch, sondern so ausgebildet, dass bei einer Rotation der Achse ein Klemmeffekt resultiert.Advantageously, the cooperating, serving as braking surfaces surfaces of the sleeve and the axis are not rotationally symmetrical, but designed so that upon rotation of the axis results in a clamping effect.
Zweckmässigerweise beschreibt die Innenfläche der Hülse und die Aussenfläche der Achse mindestens über einen bestimmten Kreisabschnitt eine schneckenförmige-(spiralförmige) Kontur entsprechend einem oder mehreren Zähnen.Conveniently, the inner surface of the sleeve and the outer surface of the axle at least over a certain circle section a helical (spiral) contour corresponding to one or more teeth.
Gemäss einer zweckmässigen Ausführungsform sind an oder in der Achsaufnahme Mitnehmer ausgebildet sind, welche mit den Achsenden der Klemmachse zusammenwirken können.According to an expedient embodiment, drivers are formed on or in the axle receptacle, which can interact with the axle ends of the clamping axle.
An den Achsenden können Aussparungen vorgesehen sein, welche einen bestimmten Freilauf des beweglichen Teils ermöglichen. Dadurch kann ein bestimmter Freilauf zwischen dem beweglichen zweiten Teil und der Achse bestehen. Dies hat den Vorteil, dass die Bremswirkung erst kurz vor der Schliessstellung eintritt. Zweckmässigerweise ist an der Achse mindestens eine Aussparung vorgesehen oder ausgebildet, welche einem an der Achsaufnahme des zweiten Teils vorgesehenen Mitnehmer einen bestimmten Freilauf ermöglicht.At the axle ends recesses may be provided which allow a certain freewheel of the movable part. This can be a certain freewheel between the movable second part and the axis. This has the advantage that the Braking effect only shortly before the closed position occurs. Conveniently, at least one recess is provided or formed on the axle, which allows a provided on the axle of the second part driver a certain freewheel.
Vorteilhaft ist die Hülse mindestens zweiteilig ausgebildet und weist ein Bremsgehäuse und mindestens eine im Bremsgehäuse aufgenommene Bremsbuchse auf. Dies hat den Vorteil, dass eine Reibwirkung zwischen der Aussenfläche der Bremsbuchse und der Innenfläche des Bremsgehäuses zustande kommen kann. Dabei kann die Bremsbuchse die Bremsbuchse ein- oder mehrteilig ausgebildet sein. Zweckmässigerweise sind die Bremsbuchsen als Halb-oder Drittelsschalen ausgebildet mit von einem zum anderen Ende - in Umtangsrichtung gesehen - kontinuierlich zunehmenden Wandstärken. Im Schnitt resultiert somit an der Innenfläche eine Verzahnung, welche formschlüssig mit der Verzahnung der Klemmachse zusammenwirken kann.Advantageously, the sleeve is formed at least in two parts and has a brake housing and at least one brake housing accommodated in the brake housing. This has the advantage that a frictional action between the outer surface of the brake bush and the inner surface of the brake housing can come about. In this case, the brake bush, the brake bushing one or more parts may be formed. Conveniently, the brake bushes are formed as half or third shells with one to the other end - seen in Umtangsrichtung - continuously increasing wall thicknesses. On average, this results in a toothing on the inner surface, which can cooperate positively with the toothing of the clamping axis.
Vorzugsweise hat die Bremsbuchse einen Schlitz einer bestimmten Breite. Dies erleichtert das Auseinanderdrücken der Bremsbuchse und ergibt einen besseren Bremseffekt. Gemäss einer bevorzugten Ausführungsform besteht bei in die Buchse eingesetzten, mehrteiligen Bremsbuchsen ein bestimmtes Spiel zwischen den einzelnen Bremsbuchsen.Preferably, the brake bush has a slot of a certain width. This facilitates the separation of the brake bushing and gives a better braking effect. According to a preferred embodiment, when used in the bush, multi-part brake bushes a certain game between the individual brake bushes.
Vorteilhaft steht die Achse über ein elastisches Rückstellmittel, z.B. einer Feder, mit der Hülse in Verbindung. Dadurch ist ein selbsttätig wirkendes Rückstellmittel geschaffen. Eine zweckmässige Ausführungsform sieht vor, dass die Hülse einen Boden besitzt, an welchem eine Torsionsfeder eingesetzt ist, die in einen Schlitz in der Achse eingreift. Beim Schliessen des Scharniers wird die Torsionsfeder verwunden und beim Öffnen sorgt die Federkraft für eine Rückstellung eines Auffangbügels.Advantageously, the axle is provided with elastic return means, e.g. a spring, in contact with the sleeve. As a result, an automatically acting return means is created. An expedient embodiment provides that the sleeve has a bottom, on which a torsion spring is inserted, which engages in a slot in the axis. When closing the hinge, the torsion spring is twisted and when opening the spring force provides for a provision of a safety catch.

Es ist denkbar, die Bremseinrichtung im Abdeckgehäuse eines Scharniertopfes unterzubringen und an der Achse der Bremseinrichtung einen Auffangbügel anzulenken.

Die Achse 17 kann drehfest mit dem zweiten Teil 15 verbunden sein, oder - es kann - wie im ersten Ausführungsbeispiel gezeigt -ein bestimmter Freilauf zwischen der Achse 17 und dem zweiten Teil 15 möglich sein. Zu diesem Zweck sind die Achsenden 23a, 23b gemäss dem gezeigten Ausführungsbeispiel Aussparungen 33a, 33b versehen, wodurch eine bestimmter Freilauf der Achse realisiert werden kann.

Eine Anwendung betrifft die Verwendung resp. Integration der Dämpfungseinrichtung in einem Möbelscharnier. Dabei kann das Gelenk, welches den Scharnierarm mit dem Scharniertopf gelenkig verbindet, durch die erfindungsgemässe Dämpfungseinrichtung ersetzt sein. Denkbar ist jedoch der Einsatz einer solchen Dämpfungseinrichtung auch in Türscharnieren, oder als Dämpfung für eine Auszugsschublade. In letzterem Fall kann am hinteren Ende der Auszugsschiene eine Rolle vorgesehen sein, welche mit der Klemmachse der Dämpfungseinrichtung in Verbindung steht.One application concerns the use resp. Integration of the damping device in a furniture hinge. In this case, the joint, which hingedly connects the hinge arm with the hinge cup, be replaced by the inventive damping device. It is conceivable, however, the use of such a damping device in door hinges, or as a damping for a drawer. In the latter case, a roller may be provided at the rear end of the drawer rail, which is in communication with the clamping axis of the damping device.
Das vierte Ausführungsbeispiel (
Im Unterschied zu den oben beschriebenen Ausführungsbeispielen besitzen die Dämpfungseinrichtungen 11a,11b eine Rückstelleinrichtung, mit welcher die Achse 17 wieder in die Ausgangslage zurückgestellt werden kann. Gemäss der gezeigten bevorzugten Ausführungsform ist die Rückstelleinrichtung durch eine Torsionsfeder 39 gebildet, welche im Boden 40 der Buchse 19 drehfest angeordnet ist. Die Torsionsfeder 39 greift in einen Schlitz 41 am distalen Ende 43 der Achse 17 ein. Das proximale Ende 45 der Achse i7 ist abgesetzt und dient zur drehfesten Befestigung eines Auffangbügels 47. Der Auffangbügel ist U-förmig ausgebildet. Er hat in den Schenkeln 48 je ein Rundloch 49, in welchem jeweils das proximale Ende 45 der Achse 17 der Dämpfungseinrichtungen 11a, 11b aufgenommen ist. Der Auffangbügel 47 befindet sich in der Offenstellung des Scharniers in ungefähr waagrechter Position. Beim Schliessen des Scharniers schlägt der Scharnierarm am Auffangbügel 47 an und drückt diesen nach unten in den Scharniertopf 38 hinein. Einer Rotation der Klemmachse 17 wirken jedoch die zwischen der Aussenfläche der Bremsbuchsen 25a, 25b und der Innenfläche der Buchse 19 erzeugten Reibungskräfte entgegen. Aufgrund geeigneter Materialwahl und Dimensionierung kann somit für jedes Scharnier die Dämpfung eingestellt werden. Wird das Scharnier geöffnet, dann wird der Auffangbügel 47 durch die Torsionsfeder wieder in die waagrechte Lage gebracht.In contrast to the exemplary embodiments described above, the damping
