Die Erfindung betrifft eine Türanordnung mit einer Zarge und mit einem Türblatt, wobei die Zarge und das Türblatt mittels mindestens zwei Scharnieren verbunden sind, wobei ein Scharnier zwei relativ zueinander zwischen einer Grundstellung und einer Endstellung schwenkbare Schenkel und mit mindestens ein entgegen der von der Grundstellung ausgehenden Schwenkrichtung wirkendes Federelement aufweist.The invention relates to a door assembly with a frame and with a door leaf, wherein the frame and the door leaf are connected by at least two hinges, wherein a hinge two relatively pivotable between a basic position and an end position leg and at least one opposite to the starting from the basic position Has pivoting direction acting spring element.

Aus der DE 1 947 513 ist ein Federscharnier bekannt, das aus jeder Winkellage in eine geschlossene Stellung zugezogen wird. Das Zuziehmoment ist in einem an die geschlossene Endlage angrenzenden Winkelbereich durch Parallelschaltung einer zweiten Feder verstärkt.From the DE 1 947 513 a spring hinge is known, which is pulled from each angular position in a closed position. The Zuziehmoment is reinforced in an adjacent to the closed end angular range by parallel connection of a second spring.

Aus der EP 1 900 896 A2 ist eine selbstschließende Tür bekannt. Die Tür wird bei der Aufschwenkbewegung entgegen der Schwerkraft und unter Belastung einer Druckfeder entlang einer Kulisse angehoben. Das Schließen wird durch die sich entspannende Druckfeder unterstützt.From the EP 1 900 896 A2 is a self-closing door known. The door is raised during the pivoting movement against gravity and under load of a compression spring along a backdrop. The closing is supported by the relaxing compression spring.

Der vorliegenden Erfindung liegt die Problemstellung zugrunde, eine Türanordnung mit mindestens zwei Scharnieren mit Selbsteinzug zu entwickeln, wobei der Selbsteinzug der Türanordnung in beide Endlagen jeweils auf einen Teilschwenkwinkel begrenzt ist.The present invention is based on the problem to develop a door assembly with at least two hinges with self-closing, wherein the self-closing of the door assembly is limited in both end positions each on a partial pivot angle.

Diese Problemstellung wird mit den Merkmalen des Hauptanspruches gelöst. Dazu trägt ein Schenkel eine Zentralwelle und der andere Schenkel eine zur Zentralwelle koaxiale Außenhülse. Zwischen der Zentralwelle und der Außenhülse ist eine Zwischenhülse angeordnet. Das Scharnier umfasst mindestens einen Verdrängungskörper, der in der Grundstellung des Scharniers in einem Durchbruch der Zwischenhülse und entweder in einer Ausnehmung der Zentralwelle oder in einer Aufnahme der Außenhülse gelagert ist, wobei zumindest in der Grundstellung die Ausnehmung und die Aufnahme nicht radial zueinander angeordnet sind. Das Federelement ist zwischen der Zwischenhülse und der in der Grundstellung den Verdrängungskörper nicht lagernden Außenhülse oder Zentralwelle angeordnet. Der an die Grundstellung angrenzende Schwenkwinkelbereich ist durch den Schwenkwinkel begrenzt, in dem die Ausnehmung und die Aufnahme radial zueinander angeordnet sind. Der beim Schwenken in die Schwenkrichtung in diesem Schwenkwinkel von der Ausnehmung in die Aufnahme oder von der Aufnahme in die Ausnehmung verdrängte Verdrängungskörper arretiert das Federelement. Ein Scharnier hat eine geöffnete Grundstellung und ein anderes Scharnier hat eine geschlossene Grundstellung. Zwischen den Schwenkwinkelbereichen, in denen jeweils ein Scharnier in seine Grundstellung gezogen wird, ist ein Freilaufwinkelbereich angeordnet.This problem is solved with the features of the main claim. For this purpose, a leg carries a central shaft and the other leg coaxial with the central shaft outer sleeve. Between the central shaft and the outer sleeve, an intermediate sleeve is arranged. The hinge comprises at least one displacement body, which is mounted in the basic position of the hinge in an opening of the intermediate sleeve and either in a recess of the central shaft or in a receptacle of the outer sleeve, wherein at least in the basic position, the recess and the receptacle are not arranged radially to each other. The spring element is arranged between the intermediate sleeve and the outer body or central shaft which does not bear the displacer body in the basic position. The pivot angle range adjacent to the basic position is limited by the pivot angle in which the recess and the receptacle are arranged radially relative to one another. The displaced in the pivoting direction in this pivoting angle of the recess in the receptacle or from the receptacle into the recess displacement body locks the spring element. One hinge has an open basic position and another hinge has a closed basic position. Between the pivoting angle ranges, in each of which a hinge is pulled into its normal position, a freewheeling angle range is arranged.

Weiterhin umfasst das Scharnier (1) z.B. drei Verdrängungskörper (90) und ein Federelement (100). Die Verdrängungskörper (90) sind im Ausführungsbeispiel Zylinder (91, 92), deren Stirnseiten (93) als Spitzen ausgebildet sind, vgl. Figur 6. Die Verdrängungskörper (90) können aber auch scheiben- oder kugelartig ausgebildet sein. Die in der Figur 2 dargestellten Verdrängungskörper (90) haben unterschiedliche Längen. Der lange zylindrische Körper (91) ist geringfügig kürzer als das Langloch (65). Sein Durchmesser ist kleiner als die Breite dieses Langlochs (65). Die beiden kürzeren Körper (92) sind kürzer als die in den Figuren 2 und 4 verdeckten, kürzeren Langlöcher (65).Furthermore, the hinge (1) comprises, for example, three displacement bodies (90) and a spring element (100). The displacement body (90) are in the embodiment cylinder (91, 92), whose end faces (93) are formed as tips, see. FIG. 6 , The displacement body (90) may also be disc or ball-shaped. The in the FIG. 2 shown displacement body (90) have different lengths. The long cylindrical body (91) is slightly shorter than the long hole (65). Its diameter is smaller than the width of this slot (65). The two shorter bodies (92) are shorter than those in the Figures 2 and 4 concealed, shorter slots (65).

Das Federelement (100) ist im Ausführungsbeispiel eine Spiralfeder (101) in der Bauform einer Torsionsfeder. Die Torsionsfeder (101) hat beispielsweise gerade Enden (102).The spring element (100) is in the exemplary embodiment, a coil spring (101) in the design of a torsion spring. The torsion spring (101) has straight ends (102), for example.

Bei der Montage des Scharniers (1) wird beispielsweise zunächst die Zwischenhülse (60) auf die Zentralwelle (51) aufgesteckt. Hierbei wird die Zwischenhülse (60) so gedreht, dass die Langlöcher (65) über den Längsnuten (55) stehen. Als nächstes werden dann die Verdrängungskörper (90) in die Langlöcher (65) eingesetzt. Nach dem Einsetzen sind die Verdrängungskörper (90) bündig mit der Mantelfläche (68) der Zwischenhülse (60) oder tauchen in die Hülsenwandung (64) ein. Die Außenhülse (71) wird so auf die Zwischenhülse (60) aufgesetzt, dass die Aufnahmen (75) nicht mit den Langlöchern (65) fluchten. Die so vorbereitete Einheit kann in die beiden miteinander fluchtenden, unter Zwischenlage der Gleithülsen (21, 22) angeordneten Schenkel (10, 30) eingeschoben werden. Nun kann der erste Haltebolzen (23) durch die Durchbrüche (19) und die Durchgangsbohrungen (54) montiert werden. Von der anderen Scharnierseite werden die Feder (100) und das Verlängerungsteil (72) eingesetzt. Zuletzt wird der zweite Haltebolzen (24) durch die Durchbrüche (34) und die Durchgangsbohrungen (74) und (82) montiert. Nach der Montage sind die Zentralwelle (51), die Zwischenhülse (60) und die Außenhülse (71) koaxial zueinander und koaxial zur Schwenkachse (5). Zum Einstellen der Schwenkwinkel des Scharniers (1) kann nach dem Herausnehmen des Haltebolzens (24) der Verlängerungsteil (72) z.B. in 90 Grad-Schritten gedreht werden. Hierzu kann z.B. ein Schraubendreher eingesetzt werden, der in den Einstellschlitz (83) eingreift.When mounting the hinge (1), for example, first the intermediate sleeve (60) is fitted onto the central shaft (51). Here, the intermediate sleeve (60) is rotated so that the slots (65) over the longitudinal grooves (55) are. Next, the displacers (90) are then inserted into the elongated holes (65). After insertion, the displacement body (90) is flush with the lateral surface (68) of the intermediate sleeve (60) or immerse in the sleeve wall (64). The outer sleeve (71) is placed on the intermediate sleeve (60) so that the receptacles (75) are not aligned with the oblong holes (65). The thus prepared unit can be inserted into the two mutually aligned, with the interposition of the sliding sleeves (21, 22) arranged legs (10, 30). Now, the first retaining pin (23) through the openings (19) and the through holes (54) are mounted. From the other hinge side, the spring (100) and the extension part (72) used. Lastly, the second retaining bolt (24) is mounted through the apertures (34) and through-holes (74) and (82). After assembly, the central shaft (51), the intermediate sleeve (60) and the outer sleeve (71) are coaxial with each other and coaxial with the pivot axis (5). To adjust the pivoting angle of the hinge (1) can after rotation of the retaining pin (24) of the extension part (72), for example, rotated in 90 degree increments. For this example, a screwdriver can be used, which engages in the adjustment slot (83).

Das so vorbereitete Scharnier wird z.B. an einer Zarge und an einem Türblatt montiert. Nach der Montage ist der zweite Scharnierzapfen (70) um die Schwenkachse (5) relativ zum ersten Scharnierzapfen (50) schwenkbar. Der Schwenkwinkel des Scharniers (1) von der Grundstellung (6) bis zur Endstellung beträgt im Ausführungsbeispiel 110 Grad. Er kann auch 130 Grad betragen.The thus prepared hinge is e.g. mounted on a frame and on a door leaf. After assembly, the second hinge pin (70) is pivotable about the pivot axis (5) relative to the first hinge pin (50). The pivot angle of the hinge (1) from the basic position (6) to the end position in the exemplary embodiment is 110 degrees. It can also be 130 degrees.

Die Figur 7 zeigt einen Längsschnitt des Scharniers (1). In der Figur 8 ist ein Querschnitt dieses Scharniers (1) dargestellt. Die Schnittebene dieser Darstellung schneidet beispielsweise den langen zylindrischen Körper (91). Das Türblatt ist beispielsweise geschlossen. Diese geschlossene Schwenkstellung des Scharniers (1) wird im Folgenden als Grundstellung (6) bezeichnet.The FIG. 7 shows a longitudinal section of the hinge (1). In the FIG. 8 is a cross section of this hinge (1) shown. The sectional plane of this illustration, for example, intersects the long cylindrical body (91). The door leaf is closed, for example. This closed pivot position of the hinge (1) is referred to below as the basic position (6).

Beim Öffnen der Tür schwenkt der bewegliche Schenkel (30) mit der Außenhülse (71) und dem Verlängerungsteil (72) in der Darstellung der Figur 8 und 9 in der Schwenkrichtung (8) entgegen dem Uhrzeigersinn. In einem an die Grundstellung (6) angrenzenden Schwenkwinkelbereich (7) dreht sich die Außenhülse (71) um die Schwenkachse (5) relativ zur feststehenden Zentralwelle (51), der Zwischenhülse (60) und den Verdrängungskörpern (90). Die Anschläge (63, 81) legen sich mit den Anschlagflächen (67, 86) an die Enden (102) der Feder (100) an. Das Federelement (100) wird tordiert und dadurch gespannt. Die Verdrängungskörper (90) behalten relativ zum feststehenden Schenkel (10) ihre Lage bei. Die Haltekräfte werden im Ausführungsbeispiel über alle drei Verdrängungskörper (90) verteilt.When opening the door, the movable leg (30) pivots with the outer sleeve (71) and the extension part (72) in the illustration of FIGS. 8 and 9 in the pivoting direction (8) counterclockwise. In a pivoting angle range (7) adjoining the basic position (6), the outer sleeve (71) rotates about the pivot axis (5) relative to the fixed central shaft (51), the intermediate sleeve (60) and the displacement bodies (90). The stops (63, 81) abut with the abutment surfaces (67, 86) against the ends (102) of the spring (100). The spring element (100) is twisted and thereby tightened. The displacers (90) maintain their position relative to the fixed leg (10). The holding forces are distributed in the embodiment over all three displacement body (90).

Der beschriebene, an die Grundstellung (6) angrenzende Schwenkwinkelbereich (7) ist begrenzt durch den Schwenkwinkel, in dem die Aufnahmen (75) der Außenhülse (71) radial außerhalb der Langlöcher (65) und der Längsnuten (55) stehen. Dieser, in der Figur 9 dargestellte Schwenkwinkel beträgt beispielsweise 45 Grad.The described, to the basic position (6) adjacent pivoting range (7) is limited by the pivot angle, in which the receptacles (75) of the outer sleeve (71) radially outside the slots (65) and the longitudinal grooves (55). This, in the FIG. 9 shown pivot angle is for example 45 degrees.

Beim Weiterschwenken in der Schwenkrichtung (8) werden die Verdrängungskörper (90) mittels der außermittig angreifenden Kraft der Zentralwelle (51) radial nach außen in Richtung der Aufnahmen (75) der Außenhülse (71) verdrängt, vgl. Figur 11. In dieser Darstellung sind die Verdrängungskörper (90) bereits aus dem Nutgrund (56) radial in Richtung der Außenhülse (71) verschoben. Die Verdrängungskörper (90) stehen hier über die Hülsenwandung (64) sowohl in Richtung der Außenhülse (71) als auch noch in Richtung der Längsnut (55) über. Beim Weiterdrehen des beweglichen Schenkels (30) in der Schwenkrichtung (8) werden die Verdrängungskörper (90) weiter in die Aufnahme (75) der Außenhülse (71) verdrängt. Nach dem Verschieben liegen die Verdrängungskörper (90) in den Langlöchern (65) und in den Aufnahmen (75). Sie verhindern ein weiteres Verdrehen der Zwischenhülse (60) relativ zur Außenhülse (71). Da die Außenhülse (71) und die Zwischenhülse (60) sich beim Weiterschwenken in die Schwenkrichtung (8) nicht weiter relativ zueinander verdrehen, wird das Federelement (100) nicht weiter gespannt. Das Federelement (100) verbleibt nun in der gespannten Stellung.Upon further pivoting in the pivoting direction (8), the displacement bodies (90) are displaced radially outwards in the direction of the receptacles (75) of the outer sleeve (71) by means of the off-center acting force of the central shaft (51). FIG. 11 , In this illustration, the displacement bodies (90) are already displaced radially outward from the groove base (56) in the direction of the outer sleeve (71). The displacement bodies (90) project over the sleeve wall (64) both in the direction of the outer sleeve (71) and also in the direction of the longitudinal groove (55). Upon further rotation of the movable leg (30) in the pivoting direction (8), the displacement body (90) are further displaced into the receptacle (75) of the outer sleeve (71). After displacement, the displacement body (90) in the slots (65) and in the receptacles (75). They prevent further rotation of the intermediate sleeve (60) relative to the outer sleeve (71). Since the outer sleeve (71) and the intermediate sleeve (60) no longer rotate relative to each other during further pivoting in the pivoting direction (8), the spring element (100) is not stretched further. The spring element (100) now remains in the cocked position.

Beim weiteren Aufschwenken des Türblatts dreht sich der bewegliche Schenkel (30) mit der Außenhülse (71) und der Zwischenhülse (60) weiter. Das Federelement (100) bleibt gespannt, so dass sich das Türblatt im Freilauf weiter öffnen lässt. Es kann jetzt in jeder Position angehalten werden und bleibt dann in dieser Stellung stehen. Eine derartige Scharnierposition ist in der Figur 10 dargestellt. Das Scharnier (1) ist in dieser Darstellung um einen Winkel von 90 Grad aufgeschwenkt.Upon further pivoting of the door leaf, the movable leg (30) continues to rotate with the outer sleeve (71) and the intermediate sleeve (60). The spring element (100) remains taut so that the door leaf can be opened further in the freewheel. It can now be stopped in any position and will then stay in that position. Such a hinge position is in the FIG. 10 shown. The hinge (1) is pivoted in this illustration by an angle of 90 degrees.

Beim Schließen des Türblatts wird das Türband (1) z.B. aus der in der Figur 10 dargestellten Position im Uhrzeigersinn, also entgegen der Schwenkrichtung (8) in die in der Figur 8 gezeigte Lage geschwenkt. Das Federelement (100) ist zunächst gespannt. Die Außenhülse (71), die Zwischenhülse (60) und die Verdrängungskörper (90) werden mitgeschwenkt. Das Türblatt kann, bis die in der Figur 9 dargestellte Position erreicht ist, jederzeit angehalten werden.When closing the door leaf, the door hinge (1), for example, from in the FIG. 10 shown position clockwise, ie opposite to the pivoting direction (8) in the in the FIG. 8 pivoted position shown. The spring element (100) is initially stretched. The outer sleeve (71), the intermediate sleeve (60) and the displacement body (90) are pivoted. The door leaf can be up in the FIG. 9 Position is reached, stopped at any time.

Sobald die Durchbrüche (65) über den Ausnehmungen (55) stehen, bewirkt die sich entspannende Feder (100) eine Relativbewegung der Zwischenhülse (60) zur Außenhülse (71). Die Verdrängungskörper (90) werden mitgenommen und von der Kante (84) der Aufnahmen (75) radial nach innen verdrängt. Die Verdrängungskörper (90) werden von den Längsnuten (55) aufgenommen. Die Feder (100) entspannt sich weiter. Sie drückt die Anschlagflächen (67, 86) der Zwischenhülse (60) und des Verlängerungsteils (72) auseinander und zieht das Türblatt in seine geschlossene Grundstellung (6).As soon as the apertures (65) are above the recesses (55), the relaxing spring (100) causes a relative movement of the intermediate sleeve (60) to the outer sleeve (71). The displacement body (90) are taken and displaced radially inward from the edge (84) of the receptacles (75). The displacement body (90) are received by the longitudinal grooves (55). The spring (100) continues to relax. It pushes the stop surfaces (67, 86) of the intermediate sleeve (60) and the extension part (72) apart and pulls the door leaf in its closed basic position (6).

Die Figuren 12 und 13 zeigen ein vereinfachtes Beispiel eines Scharniers (1) mit Freilauf und Selbsteinzug. In diesem Ausführungsbeispiel ist die Außenhülse (71) mit den Aufnahmen (75) feststehend und die Zentralwelle (51) mit dem Einstellschlitz (58) drehbar. Die Vorrichtung umfasst zwei Verdrängungskörper (90) sowie zwei Federelemente (100). Letztere sind Zugfedern (103), die jeweils zwischen zwei Federzapfen (69, 85) der Zwischenhülse (60) und der Außenhülse (71) angeordnet sind.The FIGS. 12 and 13 show a simplified example of a hinge (1) with freewheel and self-closing. In this embodiment, the outer sleeve (71) with the receptacles (75) fixed and the central shaft (51) with the adjustment slot (58) rotatable. The device comprises two displacement bodies (90) and two spring elements (100). The latter are tension springs (103) which are each arranged between two spring pins (69, 85) of the intermediate sleeve (60) and the outer sleeve (71).

Beim Drehen der Zentralwelle (51) im oder gegen den Uhrzeigersinn aus der in der Figur 12 gezeigten Lage werden die Verdrängungskörper (90) und die Zwischenhülse (60) mitgenommen. Bei diesem Drehen werden die Federelemente (100) gespannt.When turning the central shaft (51) clockwise or counterclockwise from in the FIG. 12 shown position, the displacement body (90) and the intermediate sleeve (60) are taken. During this rotation, the spring elements (100) are tensioned.

Sobald die Aufnahme (75) der Außenhülse (71) über den Durchbrüchen (65) der Zwischenhülse (60) steht, werden beim Weiterdrehen der Zentralwelle (51) die Verdrängungskörper (90) nach außen verdrängt. Sie werden aus den Längsnuten (55) der Zentralwelle (51) herausgeschoben und in die Aufnahmen (75) der Außenhülse (71) hineingeschoben. Beim Weiterdrehen der Zentralwelle (51) dreht nur diese allein weiter. Die Zwischenhülse (60) mit den Verdrängungskörpern (90) bleibt stehen. Die Federspannung wird beim Weiterdrehen der Zentralwelle (51) nicht verändert. Die Feder (100) wird mittels der Verdrängungskörper (90) arretiert.Once the receptacle (75) of the outer sleeve (71) over the openings (65) of the intermediate sleeve (60), the displacement body (90) are displaced to the outside during further rotation of the central shaft (51). They are pushed out of the longitudinal grooves (55) of the central shaft (51) and pushed into the receptacles (75) of the outer sleeve (71). Upon further rotation of the central shaft (51) only this turns on alone. The intermediate sleeve (60) with the displacement bodies (90) stops. The spring tension is not changed during further rotation of the central shaft (51). The spring (100) is locked by means of the displacement body (90).

Das Zurückdrehen der Zentralwelle (51) aus der in der Figur 13 dargestellten Position in die in der Figur 12 gezeigte Position erfolgt zunächst als freie Drehung. Sobald die Längsnuten (55) radial innerhalb der Durchbrüche (65) liegen, wird die Arretierung der Verdrängungskörper (90) aufgehoben. Die Verdrängungskörper (90) werden in die Längsnuten (55) geschoben. Die Federelemente (100) ziehen die Zwischenhülse (60) und über die Verdrängungskörper (90) die Zentralwelle (51) zurück in die Ausgangslage.The turning back of the central shaft (51) from in the FIG. 13 Position shown in the in the FIG. 12 shown position is initially as a free rotation. As soon as the longitudinal grooves (55) lie radially within the apertures (65), the locking of the displacers (90) is released. The displacement body (90) are pushed into the longitudinal grooves (55). The spring elements (100) pull the intermediate sleeve (60) and via the displacement body (90) the central shaft (51) back to the starting position.

Die Zwischenhülse (60) kann segmentartig aufgebaut sein, z.B. in zwei Schalen. Im montierten Zustand liegen die Verdrängungskörper (90) dann zwischen den Schalen.The intermediate sleeve (60) may be segmented, e.g. in two bowls. In the assembled state, the displacement body (90) then lie between the shells.

Die Zentralwelle (51) kann in einen der Scharnierflügel (10, 30) integriert sein. Ebenso ist es denkbar, dass die Außenhülse (71) in den anderen Schenkel (30, 10) integriert ist. Beispielsweise sind dann die Ausnehmungen (75) in den beweglichen Schenkel (30) eingebracht.The central shaft (51) can be integrated in one of the hinge wings (10, 30). It is also conceivable that the outer sleeve (71) in the other leg (30, 10) is integrated. For example, then the recesses (75) are introduced into the movable leg (30).

Das Scharnier (1) kann auch so aufgebaut sein, dass es in seiner Grundstellung (9) geöffnet ist, vgl. Figur 14. Beispielsweise beträgt in diesem Ausführungsbeispiel der Schwenkwinkel von der Grundstellung (9) bis zur geschlossenen Endstellung 110 Grad. In diesem Fall wird beim Schließen in einem an die Grundstellung (9) angrenzenden Schwenkwinkelbereich das Federelement (100) gespannt und in einer vorgegebenen Schwenkwinkelstellung arretiert. Das weitere Schließen des Scharniers (1) erfolgt dann ohne weiteres Spannen des Federelements (100). Beim Öffnen wird ab der vorgegebenen Schwenkwinkelstellung das Scharnier (1) unter Entspannung des Federelements (100) in die geöffnete Grundstellung (9) gezogen.The hinge (1) can also be constructed so that it is open in its basic position (9), cf. FIG. 14 , For example, in this embodiment, the pivot angle of the basic position (9) to the closed end position is 110 degrees. In this case, the spring element (100) is tensioned and locked in a predetermined swivel angle position when closing in a swivel angle region adjoining the basic position (9). The further closing of the hinge (1) then takes place without further tensioning of the spring element (100). When opening the hinge (1) is pulled from the predetermined pivoting angle position with relaxation of the spring element (100) in the open basic position (9).

Erfindungsgemäß wird bei mehreren Scharnieren (1) an einer Tür eines der Scharniere mit einer Einzugsvorrichtung in die geschlossene Stellung und eines der Scharniere mit einer Einzugsvorrichtung in die geöffnete Stellung eingesetzt . Zwischen den beiden Schwenkwinkelbereichen, in denen jeweils ein Scharnier in seine Grundstellung gezogen wird, ist ein Freilaufwinkelbereich.According to the invention is used in a plurality of hinges (1) on a door of the hinges with a collection device in the closed position and one of the hinges with a collection device in the open position. Between the two pivoting angle ranges, in each of which a hinge is pulled into its basic position, is a freewheeling angle range.

Das Scharnier (1) mit Selbsteinzug kann mit einer Endlagendämpfung und/oder einer Verzögerungsvorrichtung kombiniert sein.The self-closing hinge (1) may be combined with a cushioning and / or a retarding device.

Auch Kombinationen der verschiedenen Ausführungsbeispiele sind denkbar.Combinations of the various embodiments are conceivable.
