- the piston 50 is in interaction with the second stop element 55.
- the force of the second stop element 55 on the piston 50 decreases. This is as a dashed extension of the area A in Fig. 4 shown.
- the area B is followed by a plateau-shaped area C, in which the damping force F is constant.
- the piston 50 is no longer in interaction with the second stopper member 55 and the piston speed is constant.
- the piston 50 is still at least partially in the region of the first inner wall portion 61.
- the region C is followed by a region D in which the damping force P decreases linearly.
- the piston 50 is completely in the region of the second inner wall portion 62, wherein the effective flow cross section due to the longitudinal grooves 58 increases constantly and as a result, the damping force F decreases constantly.
- the area D is followed by a plateau-shaped area E, in which the damping force P is constant and small.
- the piston 50 is completely in the region of the third inner wall portion 63, wherein the effective flow cross section of the longitudinal grooves 58 maximum and consequently the damping force P is minimal.

- the piston 50 is in the region of the fourth inner wall portion 64, wherein due to the linear decreasing effective flow cross-section of the longitudinal grooves 58, the damping force P increases linearly.
- the area F is followed by a plateau-shaped area G, in which the damping force P is constant.
- the piston 50 is located in the region of the fifth inner wall section 65, but not yet in interaction with the first stop element 54.
- the region G is followed by a region H and a region I.
- the damping force P decreases linearly and in the region I linearly increases again.
- the piston 50 is in interaction with the first stopper member 54, wherein the piston speed decreases to zero and the force of the first stopper member 54 on the piston 50 increases.
- the superposition of these effects leads to a damping force P corresponding to the areas H and I. Reference is made to the description concerning the areas A and B.
- the pivot axis 33 of the first link 34 now lies on the line defined by the spring-pivot axes 41, 43, which coincides with the central longitudinal axis 14.
- the refrigerator door 4 opens automatically due to the spring force of the spring element 36.
- the pivot axis 33 of the first link 34 no longer lies on the straight line defined by the spring-pivot axes 41, 43, so that the spring element 36 on the fluid damper 12th an opening moment about the pivot axis 33 and thus an opening force on the refrigerator door 4 is generated.
- the piston 50 is in the middle position in the region of the third inner wall portion 63, wherein the damping force F of the fluid damper 12 is in accordance with area E in Fig. 4 results.
- the piston 50 is increasingly moved in the extension direction 56, wherein a damping force F according to the ranges F, G, H and I of the characteristic acts on the piston 50 during the extension movement.
- the piston 50 is in the area of the fifth inner wall section 65, the effective flow cross section is minimal and the damping force P maximum so that the piston 50 is braked.
- the piston 50 interacts with the first stopper member 54, which additionally applies a force against the extension direction 56 to the piston 50. The ejection movement of the piston 50 is thus gently braked and the refrigerator door 4 stops automatically in an open position. This is in Fig. 7 shown.
- the damping behavior of the fluid damper 12 is ensured that the opening and closing of the refrigerator door 4 is substantially equal, regardless of whether the refrigerator door 4 is heavily loaded or not and regardless of what force the refrigerator door 4 is pressed. This is achieved on the one hand by the speed-dependent damping behavior of the fluid damper 12 and on the other hand by the fact that the longitudinal grooves 58 a path-dependent damping behavior generate, wherein the path-dependent damping force in the region of the opening position and the closing position is greatest.
- the stopper members 54, 55 generate a damping force in these positions. This ensures that the refrigerator door 4 gently opens or closes automatically when the middle position is exceeded.

- the spring element bolts 38, 39 can be guided in the elongated holes formed as spring mounting holes 40a, 42a, so that the lever ratios be improved in the automatic opening and closing of the refrigerator door 4.
- the spring mounting holes 40a, 42a due to the spring mounting holes 40a, 42a, a larger opening moment and closing moment is generated on the fluid damper 12a, and thus a larger opening force and closing force on the refrigerator door 4.

Zur Dämpfung der Öffnungs- und Schließbewegung der Kühlschrank-Tür 4 ist eine als Fluid-Dämpfer ausgebildete Kolben-Zylinder-Dämpfungs-Einheit 12 vorgesehen. Die Kolben-Zylinder-Dämpfungs-Einheit wird nachfolgend als Fluid-Dämpfer 12 bezeichnet. Der Fluid-Dämpfer 12 weist ein im Wesentlichen zylindrisches Gehäuse 13 mit einer Mittel-Längs-Achse 14 auf. Das Gehäuse 13 ist an einem Ende mit einem Boden 15 verschlossen, der einteilig mit dem Gehäuse 13 ausgebildet ist. An dem Boden 15 ist ein erstes Befestigungs-Element 16 angeformt, das mit einer ersten Befestigungs-Bohrung 17 versehen ist. Das erste Befestigungs-Element 16 weist eine erste Schwenk-Achse 18 auf, die senkrecht zu der Mittel-Längs-Achse 14 konzentrisch zu der ersten Befestigungs-Bohrung 17 verläuft und die Mittel-Längs-Achse 14 schneidet. An der Kühlschrank-Tür 4 ist ein zweites Anlenk-Element 19 angeordnet, das eine Bohrung 20 aufweist. Das erste Befestigungs-Element 16 ist mit dem zweiten Anlenk-Element 19 durch Einfügen eines Bolzens 21 in die Bohrung 20 um die erste Schwenk-Achse 18 verschwenkbar verbunden. Prinzipiell können das erste Befestigungs-Element 16 und das zweite Anlenk-Element 19 beliebig ausgebildet sein, solange sie um die erste Schwenk-Achse 18 verschwenkbar miteinander verbunden sind. Beispielsweise können das erste Befestigungs-Element 16 und das zweite Anlenk-Element 19 als gelenkige Verbindung mit einem Kugelzapfen und einer Kugelpfanne ausgebildet sein.For damping the opening and closing movement of the
An einem dem Boden 15 gegenüberliegenden Ende des Gehäuses 13 ist ein einteilig mit diesem ausgebildeter Deckel 22 angeordnet, der konzentrisch zu der Mittel-Längs-Achse 14 eine Öffnung 23 aufweist. Durch die Öffnung 23 ist aus dem Gehäuse 13 eine Kolbenstange 24 herausgeführt, an der mittels einer Schraub-Verbindung 25 ein zweites Befestigungs-Element 26 angeordnet ist. Das zweite Befestigungs-Element 26 ist gabelförmig ausgebildet und weist einen U-förmigen Querschnitt auf. Das zweite Befestigungs-Element 26 umfasst eine erste Befestigungs-Element-Wand 27, eine parallel dazu angeordnete zweite Befestigungs-Element-Wand 28 und eine diese verbindende dritte Befestigungs-Element-Wand 29. Die dritte Befestigungs-Element-Wand 29 ist mittels der Schraub-Verbindung 25 mit der Kolbenstange 24 verbunden. Alternativ zu der Schraub-Verbindung 25 sind beliebige formschlüssige Verbindungen möglich. Die erste und die zweite Befestigungs-Element-Wand 27, 28 sind derart voneinander beabstandet, dass sie im Wesentlichen spielfrei zwischen die erste Anlenk-Element-Wand 6 und die zweite Anlenk-Element-Wand 7 einführbar sind. Die erste und zweite Befestigungs-Element-Wand 27, 28 weisen im Bereich ihrer freien Enden jeweils eine zweite Befestigungs-Bohrung 30 auf. Entsprechend weisen die erste und zweite Anlenk-Element-Wand 6, 7 zwei zueinander fluchtende Bohrungen 31 auf. Durch eine zweite Befestigungs-Bohrung 30 und eine zugehörige Bohrung 31 ist jeweils ein Bolzen 32 geführt, sodass das zweite Befestigungs-Element 26 um eine zweite Schwenk-Achse 33 schwenkbar mit dem ersten Anlenk-Element 5 verbunden ist.At an opposite end of the bottom 15 of the housing 13 a integrally formed with this
Die zweiten Befestigungs-Bohrungen 30, die Bohrungen 31 und die darin angeordneten Bolzen 32 bilden eine erste Anlenk-Verbindung 34 mit der Schwenk-Achse 33 aus, wobei die Schwenk-Achse 33 in einer Ebene betrachtet einen ersten Anlenk-Punkt definiert. Entsprechend bilden die Befestigungs-Bohrung 17, die Bohrung 20 und der Bolzen 21 eine zweite Anlenk-Verbindung 35 mit der Schwenk-Achse 18 aus, wobei die Schwenk-Achse 18 einen zweiten Anlenk-Punkt definiert. Der Fluid-Dämpfer 12 ist mittels der ersten Anlenk-Verbindung 34 direkt an dem Kühlschrank-Gehäuse 2 und mittels der zweiten Anlenk-Verbindung 35 direkt an der Kühlschrank-Tür 4 angelenkt. Der Fluid-Dämpfer 12 ist zwischen dem Kühlschrank-Gehäuse 2 und der Kühlschrank-Tür 4 dämpfend wirkend angeordnet.The second mounting bores 30, the
Der Abstand der ersten Anlenk-Verbindung 34 von der Schwenk-Achse 11 wird mit a bezeichnet. Der Abstand der zweiten Anlenk-Verbindung 35 von der Schwenk-Achse 11 wird mit b bezeichnet. Die feste Anlenkung des Fluid-Dämpfers 12 an dem Kühlschrank-Gehäuse 2 einerseits und an der Kühlschrank-Tür 4 andererseits erfolgt so, dass der Fluid-Dämpfer 12 möglichst wenig von der Kühlschrank-Tür 4 in Richtung des mit dem Kühlschrank-Gehäuse 2 eingeschlossenen Raums hervorsteht. Somit ist b wesentlich größer als a.The distance of the
Die Scharnier-Anordnung 1 weist ferner ein als Schraubenfeder ausgebildetes Feder-Element 36 auf, das zur Erzeugung einer Schwenkkraft zwischen dem Kühlschrank-Gehäuse 2 und der Kühlschrank-Tür 4 wirkend angeordnet ist. An die Enden des Feder-Elements 36 ist jeweils einteilig ein Befestigungs-Haken 37 angeformt. Zur Befestigung des Feder-Elements 36 ist ein erster Feder-Element-Bolzen 38 und ein zweiter Feder-Element-Bolzen 39 vorgesehen. Der erste Feder-Element-Bolzen 38 ist in zwei zueinander fluchtenden ersten Feder-Befestigungs-Bohrungen 40 angeordnet, die nahe der dritten Befestigungs-Element-Wand 29 in der ersten und zweiten Befestigungs-Element-Wand 27, 28 ausgebildet sind. Das Feder-Element 36 ist mit einem Befestigungs-Haken 37 um den ersten Feder-Element-Bolzen 38 geführt und um eine erste Feder-Schwenk-Achse 41 verschwenkbar mit dem zweiten Befestigungs-Element 26 verbunden. Der zweite Feder-Element-Bolzen 39 ist entsprechend in zwei zueinander fluchtenden zweiten Feder-Befestigungs-Bohrungen 42 angeordnet, die nahe der dritten Anlenk-Element-Wand 8 in der ersten und zweiten Anlenk-Element-Wand 6, 7 ausgebildet sind. Der weitere Befestigungs-Haken 37 ist um den zweiten Feder-Element-Bolzen 39 geführt, sodass das Feder-Element 36 um eine zweite Feder-Schwenk-Achse 43 verschwenkbar mit dem ersten Anlenk-Element 5 verbunden ist. Das Feder-Element 36 ist somit zwischen der ersten und zweiten Befestigungs-Element-Wand 27, 28 angeordnet und zwischen den Feder-Element-Bolzen 38, 39 vorgespannt.The
Der Feder-Element-Bolzen 39 und die Feder-Befestigungs-Bohrungen 42 bilden eine erste Feder-Anlenk-Verbindung 44 mit der Feder-Schwenk-Achse 43 aus, wobei die Feder-Schwenk-Achse 43 in einer Ebene betrachtet einen ersten Feder-Anlenk-Punkt definiert. Entsprechend bildet der Feder-Element-Bolzen 38 und die Feder-Befestigungs-Bohrungen 40 eine zweite Feder-Anlenk-Verbindung 45 mit der Feder-Schwenk-Achse 41 aus, wobei die Feder-Schwenk-Achse 41 einen zweiten Feder-Anlenk-Punkt definiert. Mittels der ersten Feder-Anlenk-Verbindung 44 ist das Feder-Element 36 direkt an dem Kühlschank-Gehäuse 2 und mittels der zweiten Feder-Anlenk-Verbindung 45 direkt an dem Fluid-Dämpfer 12 angelenkt.The
Die erste Anlenk-Verbindung 34 ist relativ zu dem Kühlschrank-Gehäuse 2 und dem ersten Anlenk-Element 5 ortsfest. Des Weiteren ist die erste Feder-Anlenk-Verbindung 44 relativ zu dem Kühlschrank-Gehäuse 2 und dem ersten Anlenk-Element 5 ortsfest. Die zweite Feder-Anlenk-Verbindung 45 ist relativ zu dem Kühlschrank-Gehäuse 2 beweglich. In einer Mittel-Position - die in
Im Folgenden wird unter Bezugnahme auf
Innerhalb des Gehäuses 13 ist zwischen der Führungs- und Dichtungs-Einheit 47 und dem Kolben 50 ein erstes elastisches Anschlag-Element 54 angeordnet, das ringförmig die Kolbenstange 24 umgibt und gegen die Innenwand 48 und die Führungs- und Dichtungs-Einheit 47 anliegt. Das erste Anschlag-Element 54 ist als Elastomer-Ring ausgebildet. Entsprechend ist zwischen dem Boden 15 und dem Kolben 50 ein zweites elastisches Anschlag-Element 55 in dem Gehäuse 13 angeordnet. Das zweite Anschlag-Element 55 ist als Schraubenfeder ausgebildet und liegt gegen den Boden 15 und teilweise gegen die Innenwand 48 an. Prinzipiell können die Anschlag-Elemente 54, 55 beliebig ausgebildet sein, beispielsweise als Tellerfeder, Schraubenfeder, Elastomer oder PU-Schaum.Within the
Der Fluid-Dämpfer 12 weist eine parallel zu der Mittel-Längs-Achse 14 verlaufende Ausschub-Richtung 56 auf. Zur Erzeugung einer Dämpfung sind in dem Kolben 50 über seinen Umfang verteilt Dämpfungs-Bohrungen 57 angeordnet, die den Kolben 50 durchdringen und parallel zu der Ausschub-Richtung 56 verlaufen. Die Dämpfungs-Bohrungen 57 verbinden den ersten Teil-Arbeitsraum 51 mit dem zweiten Teil-Arbeitsraum 52 und erzeugen bei einer Bewegung des Kolbens 50 eine geschwindigkeitsabhängige Dämpfungskraft. Die Dämpfungs-Bohrungen 57 können zum Teil durch Ventile verschlossen sein, die bei einer Bewegung in Ausschub-Richtung 56 offen sind und bei einer Bewegung entgegen die Ausschub-Richtung 56 geschlossen sind. Durch derartige Ventile kann bei einer Bewegung des Kolbens 50 entgegen die Ausschub-Richtung 56 eine größere Dämpfungskraft erzeugt werden, als bei einer Bewegung in Ausschub-Richtung 56.The
In der Innenwand 48 sind gleichmäßig über den Umfang verteilt mehrere Längs-Nuten 58 angeordnet. Im Bereich dieser Längs-Nuten 58 liegt der Kolben 50 nicht dicht an der Innenwand 48 an. Es wird ein StrömungsKanal 59 zwischen dem Kolben 50 und dem Nut-Grund 60 der Längs-Nuten 58 gebildet. Ausgehend vom Boden 15 existiert zunächst ein erster Innenwand-Abschnitt 61, entlang dessen keine Längs-Nuten 58 vorgesehen sind. Daran schließt sich ein zweiter Innenwand-Abschnitt 62 an, entlang dessen der Querschnitt der Längs-Nuten 58 entlang der Ausschub-Richtung 56 konstant von Null an zunimmt. Daran schließt sich ein dritter Innenwand-Abschnitt 63 an, entlang dessen die Längs-Nuten 58 einen im Wesentlichen konstanten Querschnitt aufweisen. Es folgt ein vierter Innenwand-Abschnitt 64, entlang dessen der Querschnitt der Längs-Nuten 58 über eine im Vergleich zu dem zweiten Innenwand-Abschnitt 62 kürzere Länge konstant auf Null abnimmt. Daran schließt sich ein fünfter Innenwand-Abschnitt 65 an, entlang dessen wiederum keine Längs-Nuten 58 vorhanden sind.In the inner wall 48 a plurality of

Im Folgenden wird das Dämpfungsverhalten der Kühlschrank-Tür 4 beim Öffnen und Schließen beschrieben. Es wird davon ausgegangen, dass die Kühlschrank-Tür 4 zunächst geschlossen ist, wie dies in
Beim Schließen der Kühlschrank-Tür 4 muss ausgehend von der in
Durch das Dämpfungsverhalten des Fluid-Dämpfers 12 ist sichergestellt, dass das Öffnen und Schließen der Kühlschrank-Tür 4 im Wesentlichen gleich verläuft, unabhängig davon, ob die Kühlschrank-Tür 4 schwer beladen ist oder nicht und unabhängig davon mit welcher Kraft die Kühlschrank-Tür 4 betätigt wird. Dies wird einerseits durch das geschwindigkeitsabhängige Dämpfungsverhalten des Fluid-Dämpfers 12 erzielt und andererseits dadurch, dass die Längs-Nuten 58 ein wegabhängiges Dämpfungsverhalten erzeugen, wobei die wegabhängige Dämpfungskraft im Bereich der Öffnungs-Position und der Schließ-Position am größten ist. Zusätzlich erzeugen die Anschlag-Elemente 54, 55 in diesen Positionen eine Dämpfungskraft. Dadurch ist sichergestellt, dass die Kühlschrank-Tür 4 beim Überschreiten der Mittel-Position sanft selbsttätig öffnet bzw. schließt.By the damping behavior of the

Beim Öffnen und Schließen der Kühlschrank-Tür 4 können sich die Feder-Element-Bolzen 38, 39 in den als Langlöcher ausgebildeten Feder-Befestigungs-Bohrungen 40a, 42a geführt bewegen, sodass die Hebelverhältnisse beim selbsttätigen Öffnen und Schließen der Kühlschrank-Tür 4 verbessert werden. Im Vergleich zu dem ersten Ausführungsbeispiel wird aufgrund der Feder-Befestigungs-Bohrungen 40a, 42a ein größeres Öffnungsmoment und Schließmoment auf den Fluid-Dämpfer 12a und somit eine größere Öffnungskraft und Schließkraft auf die Kühlschrank-Tür 4 erzeugt. Durch die Feder-Befestigungs-Bohrungen 40a, 42a erfolgt eine Anlenk-Punkt-Verschiebung und eine Verschiebung der Feder-Schwenk-Achsen 41, 43.When opening and closing the
Vorteilhaft ist auch, wenn mindestens einer der Feder-Element-Bolzen 38, 39 zur Einstellung des Totpunktes, das heißt des Öffnungswinkels α in der Mittel-Position, relativ zu der als Langloch ausgebildeten und zugehörigen Feder-Befestigungs-Bohrung 40a, 42a fixierbar ist. Die Fixierung kann beispielsweise durch ein Gewinde und eine darauf aufgeschraubte Mutter erfolgen. Durch eine Verschiebung und Fixierung der Feder-Schwenk-Achsen 41, 43 kann der Totpunkt und die Hebelverhältnisse, beispielsweise bei der Montage der Scharnier-Anordnung 1a, in weiten Bereichen eingestellt werden. Ergänzend wird auf das nachfolgend beschriebene vierte und fünfte Ausführungsbeispiel verwiesen. Hinsichtlich der weiteren Funktionsweise der Scharnier-Anordnung 1a wird auf das erste Ausführungsbeispiel verwiesen.It is also advantageous if at least one of the

Zur Positionierung des zweiten Feder-Element-Bolzens 39c entlang der als Langloch ausgebildeten zweiten Feder-Befestigungs-Bohrungen 42c weist die Scharnier-Anordnung 1c eine Stell-Schraube 71 auf. Die Stell-Schraube 71 ist durch eine Stell-Schrauben-Bohrung 72 an einer vierten Anlenk-Element-Wand 73 des ersten Anlenk-Elements 5c geführt. Die vierte Anlenk-Element-Wand 73 verbindet die erste und zweite Anlenk-Element-Wand 6c, 7c und ist im Wesentlichen senkrecht zu der dritten Anlenk-Element-Wand 8c angeordnet. Die Stell-Schraube 71 ist mittels eines Sicherungs-Ringes 74 in der Stell-Schrauben-Bohrung 72 gesichert. Die Stell-Schraube 71 weist ein Stell-Schrauben-Außengewinde 75 auf, das in ein Halte-Klammer-Innengewinde 76 eingeschraubt ist. Das Halte-Klammer-Innengewinde 76 ist in der dritten Halte-Klammer-Wand 69 mittig und gegenüberliegend zu der Stell-Schrauben-Bohrung 72 ausgebildet.For positioning the second spring-
Mittels der Stell-Schraube 71 ist eine Anlenk-Punkt-Verschiebung, d. h. eine Verschiebung der zweiten Feder-Schwenk-Achse 43, der ersten Feder-Anlenk-Verbindung 44c möglich. Wird die zweite Feder-Schwenk-Achse 43 mittels der Stell-Schraube 71 in Richtung der Kühlschrank-Tür 4 verlagert, so ändert sich das Öffnungs- und Schließverhalten der Kühlschrank-Tür 4 derart, dass das selbsttätige Schließen der Kühlschrank-Tür 4 später beginnt und das selbsttätige Öffnen der Kühlschrank-Tür 4 früher. Wird die zweite Feder-Schwenk-Achse 43 mittels der Stell-Schraube 71 in Richtung der vierten Anlenk-Element-Wand 73 verlagert, so ändert sich das Öffnungs- und Schließverhalten der Kühlschrank-Tür 4 derart, dass das selbsttätige Schließen der Kühlschrank-Tür 4 früher beginnt, das selbsttätige Öffnen der Kühlschrank-Tür 4 später. Mittels der Stell-Schraube 71 kann somit eine individuelle Feinabstimmung des Öffnungs- und Schließverhaltens der Scharnier-Anordnung 1c erfolgen. Dies kann beispielsweise bei der Montage der Scharnier-Anordnung 1c oder durch den späteren Benutzer erfolgen. Alternativ zu der Stell-Schraube 71 kann auch ein Exzenter verwendet werden. Hinsichtlich der weiteren Funktionsweise der Scharnier-Anordnung 1c wird auf die vorangegangenen Ausführungsbeispiele verwiesen.By means of the adjusting
