Description

Türband  hinge
Die vorliegende Erfindung betrifft ein Türband nach dem Oberbegriff des Anspruchs 1. The present invention relates to a door hinge according to the preamble of claim 1.
Türbänder bestehen aus relativ vielen Teilen, wenn sie eine geeignete Lagerung aufweisen sollen . So ist ein Türband bekannt, bei dem eine Kugel zwischen zwei Gleitlagerelementen einliegt. Die Gleitlagerelemente werden dabei in die Lagerabschnitte des äußeren Türbandteils eingeschraubt oder mittels Schrauben in Position gehalten. Dieses Türband besteht aus unverhältnismäßig vielen Teilen, wodurch der Zusammenbau aufwändig und kostspielig ist. Door hinges consist of relatively many parts, if they should have a suitable storage. Thus, a door hinge is known in which a ball rests between two sliding bearing elements. The sliding bearing elements are thereby screwed into the bearing sections of the outer hinge part or held by means of screws in position. This door hinge consists of disproportionately many parts, making the assembly complex and costly.
Ein Türband aus wenigen Teilen und dessen Herstellungsverfahren ist ferner aus DE 102009031829 AI vorbekannt. Dieses Türband zeichnet sich dadurch aus, dass die Lagerabschnitte des äußeren Türbandteils durch Drehen oder Kaltfließpressen hergestellt sind und an ihren äußeren Stirnseiten verschlossen sind . An ihren dem Lagerabschnitt des inneren Türbandteils zugewandten Stirnseiten weisen die Lagerabschnitte des äußeren Türbandteils entweder einen Vorsprung auf, der in das im Lagerabschnitt des inneren Türbandteils einliegende Gleitelement eingreift oder sie weisen eine Ausnehmung auf, in der das Gleitelement oder ein bolzenförmiges Teil des inneren Türbandteils einliegt. Wie in Figur 3 von DE 102009031829 AI dargestellt, weisen die Böden der die Ausnehmungen bildenden Sacklöcher der Lagerabschnitte des äußeren Türbandteils eine komplizierte halbkugelförmige Form auf, die kompliziert und teuer in der Herstellung ist. Aufgabe der vorliegenden Erfindung ist es, dass aus DE 102009031829 AI bekannte Türband derart weiterzubilden, dass keine komplizierte Herstellung der halbkugelförmigen Böden der Sacklöcher notwendig ist. A door hinge of a few parts and its manufacturing method is also known from DE 102009031829 AI previously known. This door hinge is characterized in that the bearing portions of the outer hinge part are made by turning or cold extrusion and are closed at their outer end faces. At their end portions facing the bearing portion of the inner door hinge part, the bearing portions of the outer door hinge part either have a projection which engages with the sliding element inserted in the bearing section of the inner door hinge part or they have a recess in which the sliding element or a bolt-shaped part of the inner door hinge part rests , As shown in Figure 3 of DE 102009031829 AI, the bottoms of the recesses forming blind holes of the bearing portions of the outer door hinge part to a complicated hemispherical shape, which is complicated and expensive to manufacture. Object of the present invention is that from DE 102009031829 AI known door hinge educate such that no complicated production of the hemispherical bottoms of the blind holes is necessary.
Diese Aufgabe wird erfindungsgemäß mit einem Türband mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen des Türbandes nach Anspruch 1 ergeben sich durch die Merkmale der auf den Anspruch 1 rückbezogenen Unteransprüche. This object is achieved with a door hinge with the features of claim 1. Further advantageous embodiments of the door hinge according to claim 1 result from the features of the dependent on the claim 1 dependent claims.
Das erfindungsgemäße Türband zeichnet sich dadurch aus, dass es aus einfach herzustellenden Teilen zusammengesetzt ist. So können die Lagerabschnitte des äußeren Türbandes leicht aus Vollprofilen oder als Drehteil hergestellt werden, in die eine stirnseitige Sacklochbohrung mit möglichst flacher Bodenwandung eingearbeitet wird . In diese Sacklochbohrung werden die beiden, insbesondere vorteilhaft aus Kunststoff gefertigten, Gleitschalenelemente und die dazwischen angeordnete Kugel, welche vorteilhaft auf einem Metall gefertigt sein kann, angeordnet, wobei das erste Gleitschalenelement an der Bodenwandung des Sacklochs des Lagerabschnitts anliegt. The door hinge according to the invention is characterized in that it is composed of easy-to-produce parts. Thus, the bearing portions of the outer door hinge can be easily made of solid profiles or as a turned part, in which a frontal blind hole is incorporated with the lowest possible bottom wall. In this blind hole, the two, in particular advantageously made of plastic, Gleitschalenelemente and the ball arranged therebetween, which can be advantageously made on a metal, arranged, wherein the first sliding shell element rests against the bottom wall of the blind hole of the bearing section.
Die Gleitschalenelemente weisen eine kugelkalottenförmige Lagerfläche für die Kugel auf, so dass sich durch die großen Gleitflächen nur geringe Reibungskräfte und damit einhergehend ein geringer Verschleiß ergibt. The Gleitschalenelemente have a spherical cap bearing surface for the ball, so that only small frictional forces and concomitantly resulting in low wear due to the large sliding surfaces.
Der Lagerabschnitt des inneren Türbandteils bildet mit seinen beiden axialen Enden Vorsprünge, die jeweils in die stirnseitige Ausnehmung eines zweiten Gleitschalenelements eingreifen und sich auf deren möglichst ebenen Bodenwandungen abstützen. Die Elemente sind alle rotationssymmetrisch ausgebildet, so dass sie sich zueinander um ihre Achse verdrehen können. The bearing portion of the inner door hinge part forms with its two axial ends projections which engage respectively in the frontal recess of a second Gleitschalenelements and are supported on the flatest possible floor walls. The elements are all rotationally symmetrical, so that they can rotate relative to each other about their axis.
Selbstverständlich ist es auch möglich, dass die Lagerabschnitte des äußeren Türbandteils entsprechende Vorsprünge wie der zuvor beschriebene Lagerabschnitt des inneren Türbandteils aufweisen, wobei dann der Lagerabschnitt des inneren Türbandteils entsprechende stirnseitig eingebrachte Sacklochbohren aufweisen muss, in denen die Gleitschalenelemente und die Kugel einliegen. Auch ist es im Sinne der Erfindung, dass der Lagerabschnitt des inneren Türbandteils an einem axialen Ende einen Vorsprung und an der anderen axialen Stirnseite eine Sacklochbohrung aufweist, wobei dann ein Lagerabschnitt des äußeren Türbandteils eine korrespondierende Sacklochbohrung und der andere Lagerabschnitt einen korrespondierenden Vorsprung aufweisen muss. Of course, it is also possible that the bearing portions of the outer door hinge part have corresponding projections as the bearing portion of the inner door hinge part described above, in which case the bearing portion of the inner door hinge part must have corresponding frontally introduced blind holes, in which the Gleitschalenelemente and the ball einliegen. It is also within the meaning of the invention that the bearing portion of the inner door hinge part at one axial end has a projection and at the other axial end side has a blind hole, in which case a bearing portion of the outer hinge part a corresponding blind hole and the other bearing portion must have a corresponding projection.
Nach dem Zusammensetzen der einzelnen Teile des erfindungsgemäßen Türbandes werden die Lagerabschnitte mit den Bandlappen verbunden, was durch eine Schweißnaht erfolgen kann. Beim Zusammenschweißen müssen die Lagerabschnitte des äußeren Türbandteils gegeneinander gedrückt werden oder so zusammengeschoben und gehalten werden, dass das fertige Türband spielfrei ist. After assembly of the individual parts of the door hinge according to the invention, the bearing sections are connected to the hinge tabs, which can be done by a weld. When welding together, the bearing sections of the outer door hinge part must be pressed against each other or pushed together and held so that the finished door hinge is free of play.
Die Kugel und die Gleitschalenelemente sind vorteilhaft aus verschiedenen Materialien gefertigt, welche zusammen gute Gleiteigenschaften aufweisen. The ball and the sliding shell elements are advantageously made of different materials, which together have good sliding properties.
Nachfolgend wird eine mögliche Ausführungsform des erfindungsgemäßen Türbandes anhand von Zeichnungen näher erläutert. Hereinafter, a possible embodiment of the door hinge according to the invention will be explained in more detail with reference to drawings.

Schweißnähte S an dem Bandlappen 1 angeschweißt sind . Das innere Türbandteil ist durch den Bandlappen 4 und den daran angeschweißten Lagerabschnitt 5 gebildet. Die Lagerabschnitte 2 des äußeren Türbandteils sind zylindrische Körper, die eine axiale Sacklochbohrung 2a mit Innendurchmesser RH aufweisen, deren Bodenwandung 2d möglichst eben ausgebildet ist. Als erstes Teil wir das erste Gleitschalenelement 6 in die Sacklochbohrung 2a eingelegt, welches aus einem geeigneten Kunststoff gefertigt, insbesondere ein Kunststoffspritzteil, ist. Das erste Gleitschalenelement 6 hat eine nach innen gewölbte, d . h . konkave, kugelkalottenförmige Stirnwandung 6a, die möglichst vollflächig an der Kugel 7 zur Anlage gelangt. Die äußere zylinderförmige Wandung des ersten Gleitschalenelementes 6 liegt ebenfalls möglichst vollflächig an der Innenwandung der Sacklochbohrung 2a an . Welds S are welded to the hinge flap 1. The inner door hinge part is formed by the hinge flap 4 and the bearing section 5 welded thereto. The bearing sections 2 of the outer door hinge part are cylindrical bodies which have an axial blind hole 2a with inner diameter RH, whose bottom wall 2d is formed as flat as possible. As the first part, we inserted the first sliding shell element 6 in the blind hole 2 a, which is made of a suitable plastic, in particular a plastic injection molded part. The first sliding shell element 6 has an inwardly curved, d. H . concave, spherical cap-shaped end wall 6a, which reaches as fully as possible on the ball 7 to the plant. The outer cylindrical wall of the first sliding shell element 6 also lies as fully as possible against the inner wall of the blind hole 2 a.
Das zweite Gleitschalenelement 8 weist ebenfalls eine nach innen gewölbte, d . h . konkave, kugelkalottenförmige Stirnwandung 8a auf, wobei die beiden kugelkalottenförmigen Wandungen 6a, 8a derart ausgebildet sind, dass sich die beiden Gleitschalenelemente 6, 8 mit dazwischen angeordneter Kugel 7 im zusammengesetzten Zustand des Türbandes nicht berühren . Das zweite Gleitschalenelement 8 weist an seiner der Kugel 7 abgewandten Stirnseite eine zentrische Ausnehmung 8c auf, in die der zylindrische Vorsprung 5b, 5c des korrespondierenden Lagerabschnitts 2 eingreift, wobei sich der Vorsprung 5b, 5c mit seiner Stirnseite 5d an der Bodenwandung 8b der zentrischen Ausnehmung 8c abstützt. The second sliding shell element 8 also has an inwardly curved, d. H . concave, spherical cap-shaped end wall 8a, wherein the two spherical cap-shaped walls 6a, 8a are formed such that the two Gleitschalenelemente 6, 8 with interposed ball 7 do not touch in the assembled state of the door hinge. The second sliding shell element 8 has on its end facing away from the ball 7 a central recess 8c, in which the cylindrical projection 5b, 5c of the corresponding bearing portion 2 engages, wherein the projection 5b, 5c with its end face 5d on the bottom wall 8b of the central recess 8c supported.
Der zylindrische Vorsprung 5b, 5c, weist einen Außendurchmesser RA2 auf, der kleiner gleich dem Innendurchmesser RI2 der Ausnehmung 8c des zweiten Gleitschalenelementes 8 ist. The cylindrical projection 5b, 5c, has an outer diameter R A2 , which is less than or equal to the inner diameter R I2 of the recess 8c of the second sliding shell element 8.
Zwischen dem zylinderförmigen Ende 5b, 5c und dem Mittelteil 5m ist ein weiterer Abschnitt 5a angeordnet, dessen Außendurchmesser Rai größer ist als der Außendurchmesser des Endes 5b, 5c. Die axiale Länge der Bereiche 5a, 5b und 5c sowie der Anordnung aus Gleitschalenelementen 6, 8 und der Kugel ist so bemessen, dass die Stirnwandung des Mittelteils 5m nicht gegen die Lagerabschnitte 2 des äußeren Türbandteils 1, 2 stößt. Between the cylindrical end 5b, 5c and the central part 5m, a further section 5a is arranged, the outer diameter R a i is greater than the outer diameter of the end 5b, 5c. The axial length of the areas 5a, 5b and 5c and the arrangement of Gleitschalenelementen 6, 8 and the ball is dimensioned so that the end wall of the central portion 5m does not abut against the bearing portions 2 of the outer door hinge part 1, 2.
Der Mittelteil 5m kann eine Ausnehmung 5s aufweisen, welche insbesondere mittels eines Fräsvorganges herstellbar ist, in die der Bandlappen 4 mit seiner schmalen Seite einlegbar ist. Der Bereich 5b kann eine gebördelte Oberfläche aufweisen, so dass das Gleitschalenelement 8 auf das Ende 5b, 5c aufgeschoben werden kann und dann dort verliersicher verweilt, so dass der Zusammenbau des Türbandes leichter erfolgen kann. The central part 5m may have a recess 5s, which can be produced in particular by means of a milling process, into which the hinge plate 4 can be inserted with its narrow side. The region 5b may have a flared surface, so that the sliding shell element 8 can be pushed onto the end 5b, 5c and then lingering there captive, so that the assembly of the door hinge can be made easier.
