Definitions
- GB 2 479 145 A relates to a door closer with a closer shaft, with a arranged on one side of the closer shaft closer spring unit and with a damping piston on the opposite side of the closer shaft.
- the closer shaft is provided with a central drive contour and with the middle drive contour on both sides adjacent outer drive contours. Due to an opening movement of the door leaf, the closer spring unit is acted upon both by the central drive contour and by the outer drive contours and thereby tensioned.
- the middle drive contour and the outer drive contours of the prior art door closer thus form a spring piston drive contour. If the open door is released, then the conditions arise again before the beginning of the opening movement of the door leaf. A loading of the damping piston takes place exclusively by the outer drive contours, but not by the average drive contour.
- EP 2 426 300 A1 discloses a door closer with a closer shaft on which a central drive contour and two outer drive contours are provided.
- the outer drive contours interact with a spring piston acted upon by a closing spring, the central drive contour with a damping piston acted upon by a damping spring.
- end surfaces are provided on the spring piston, which are supported on counter surfaces of the outer drive contours.
- the damping piston has an end face, which is associated with a counter surface on the central drive contour.
- the mating surfaces of the outer drive contours on the one hand and the mating surface of the central drive contour on the other hand extend at an angle of 90 ° to each other.
- the closer shaft When opening the provided with the known door closer door leaf, the closer shaft rotates from the starting position in a direction of rotation opening through an angle of 90 °.
- the spring piston is acted upon by the outer drive contours and moved under tensioning of the closing spring.
- the previously tensioned closing spring drives the closer shaft in a direction opposite to the direction of rotation opening via the spring piston.
- the central drive contour acts on the damping piston. Accordingly, the circumferential angle over which the outer drive contours serving as the spring piston drive contour rotate under tensioning of the closer spring as well as the circumferential angle over which the central drive contour serving as damping piston drive contour under the action of the damping piston rotates 90 °. A mutual overlap of the two circumferential angles does not exist.
- the spring piston drive contour and the damping piston drive contour thus extend over equally large circumferential angles about the axis of the closer shaft and close to each other in the circumferential direction of the heart-shaped disc.
- the spring piston drive contour is a roller rotatably mounted on the spring piston, the damper piston drive contour assigned to a rotatably mounted on the damping piston roller. If the door provided with the door closer is pivoted in the opening direction, the closer shaft and the heart-shaped disk mounted thereon rotate in the rotational opening direction and the spring-piston-side roller rolls on the spring-piston drive contour of the heart-shaped disk.
- the spring piston side roller and with this the spring piston by the spring piston drive contour in the radial direction of the axis of the closer shaft is moved away from the latter.
- the spring piston biases a closing spring of the door closer, which is supported on the spring piston at its side remote from the closer shaft side.
- the roller mounted on the damping piston of the door closer rolls on the damping piston drive contour of the heart-shaped disc.
- the previously tensioned closing spring on the spring piston and the spring piston side roller rotation of the closer shaft against the rotational opening direction and thus an automatic closing of the door can cause the spring piston side roller on the spring piston drive contour of the heart-shaped disc be supported on this side of the heart.
- this condition is only fulfilled if the opening angle over which the door leaf provided with the door is opened is less than 180 °.
- the spring-piston-side roller would override the apex toward the damping piston drive contour.
- the door opening angle at which the previously known door closer can effect an automatic closing movement is accordingly limited.
- the advantage of the known door closer insofar as the power transmission between the heart-shaped disc and the piston-side rollers supported thereon is largely along the median plane of the door closer and consequently the roller axes are arranged along the median plane of the door closer. Due to this arrangement of the roller axes results on the one hand a slim design of the door closer.
- the effective between the heart-shaped disc and the spring piston and the damping piston of the prior art door closer forces are introduced symmetrically into the spring piston and the damping piston. In turn, acting on the spring piston and the damping piston tilting moments are avoided, as a result of which the friction between the spring piston and the damping piston on the one hand and the piston leading door closer housing on the other hand would be increased.
- the object of the present invention is to develop the prior art to the effect that even large door opening angle, in particular door opening angle of at least 180 °, can be mastered with a slim door closer construction.
- the spring piston drive contour and the damping piston drive contour along the contour axis of rotation are offset from each other.
- the spring piston drive contour and the damping piston drive contour of the door closer according to the invention extend with mutual overlap of their circumferential angles about the contour axis of rotation.
- the mutual offset of the spring piston drive contour and the damping piston drive contour along the contour axis of rotation creates the prerequisite that both the spring piston drive contour and the damping piston drive contour in the circumferential direction can extend around the contour axis of rotation over a circumferential angle of more than 180 °.
- Such a "long" spring piston drive contour offers even at opening angles of 180 ° and more the ability to implement the force exerted by the relaxing closing spring force in a closing movement of the closer shaft.
- the available length of the damping piston drive contour ensures that the damping piston drive contour can be effective during the entire closing movement in a sense that damps the closing movement.
- the force can be applied to the spring piston drive contour and / or on the damping piston drive contour at locations that lie together with the contour axis of rotation along the median plane of the door closer.
- a closing movement can be effected starting from a large door opening angle, in particular starting from a door opening angle of 180 ° and more, without the force transmission to the spring piston drive contour and / or to the damping piston drive contour for this purpose considerable extent must be offset laterally against the center line of the door closer. After such a lateral offset is dispensable, door closers according to the invention can build narrow and consequently slim.
- a preferred type of invention is characterized in that the mutual loading of the spring piston drive contour and the spring piston and / or the mutual loading of the damping piston drive contour and the damping piston takes place symmetrically on the piston side. Due to the symmetry of the introduction of force acting on the spring piston and / or the damping piston tilting moments are avoided.
- the force is applied between the spring piston drive contour and the spring piston and / or the damping piston drive contour and the damping piston via a piston-side support roller, which extends about a parallel to the contour axis of rotation roller rotation axis is rotatable.
- a piston-side support roller which extends about a parallel to the contour axis of rotation roller rotation axis is rotatable.
- the damping piston drive contour comprises a plurality along the contour axis offset from each other arranged drive part contours.
- the circumferential angle of the spring piston drive contour and the damping piston drive contour engages the spring piston drive contour with at least one height-reduced length section in the space between two adjacent drive sub-contours of the damping piston drive contour.
- the spring piston drive contour is formed in several parts.
- the damping piston drive contour is arranged in the region of mutual overlap of the circumferential angle of damping piston drive contour and spring piston drive contour with a reduced-height portion between two adjacent drive part contours of the spring piston drive contour.
- piston-side support roller which is intended to support the damping piston on the multi-part damping piston drive contour or for supporting the spring piston on the multi-part spring piston drive contour, in their shape to the multi-part damping piston drive contour or the spring piston Drive contour adapted.
- the piston-side support roller is articulated along the roller axis of rotation parallel to the contour axis of rotation to form spaces between adjacent axial roller sections. Rolls the piston-side support roller in the region of mutual overlap of the circumferential angle of damping piston drive contour and spring piston drive contour, the gap between the adjacent roller sections at the height of engaging between two drive part contours reduced-height portion of the spring piston drive contour or Dämpfungskolben- drive contour.
- the spring piston drive contour or the damping piston drive contour can also be designed in the region of the mutual overlap of its circumferential angle almost arbitrarily and only tuned to the torque curve to be guaranteed by it.
- the respective drive contour can protrude in the circumferential direction from the damping piston drive contour and the spring piston drive contour in the radial direction of the contour axis with respect to the drive partial contours adjacent to it.

- FIGS. 1 to 3 show the door closer 1 with the door closed 3.
- the spring piston 13 and the spring piston-side support roller 14 are located along the longitudinal center plane of the door closer housing 2 in its closing shaft end position.

- a housing space 31 between the second housing cover 26 and the damping piston 21 has its minimum Volume up.
- FIG. 2 is directed in a clockwise direction.
- the closer to the shutter arm 9 rotatably connected closer shaft 7 thus rotates about its axis 8 in a rotational opening direction 32.
- the spring piston drive contour 15 and the damping piston drive contour 24 a rectified rotational movement about the axis acting as a contour axis of rotation 8 of the closer shaft 7th out.
- the spring piston-side support roller 14 rolls on the spring piston drive contour 15. Due to the geometry of the spring piston drive contour 15, the location of the support of the spring piston-side support roller 14 on the spring piston drive contour 15 is displaced away from the axis 8 of the closer shaft 7. The spring piston 13 is therefore by the about the axis 8 of the closer shaft 7 rotating spring piston drive contour 15 on the spring piston side support roller 14 in FIG. 2 moved to the right. In this case, the spring piston 13 biases the closer spring unit 10. The rotational movement of the spring piston drive contour 15 about the (contour-rotation) axis 8 of the closer shaft 7 is thus a clamping rotary movement.
- the course of the spring piston drive contour 15 about the axis 8 of the closer shaft 7 is selected such that the center distance of the support of the spring piston side support roller 14 on the spring piston drive contour 15 increases with increasing door opening angle and consequently the opening movement of the door leaf 3 of the closer spring unit 10, a resistance decreasing with increasing door opening angle is counteracted.

- the spring piston-side support roller 14 acts on the spring piston drive contour 15 and thereby puts them into a rotational movement, the direction of the rotational opening direction 32 is opposite, and ends when the spring piston drive contour 15 in its rotational position in accordance with FIGS. 2 and 3 is reset.
- the housing space 31 between the damping piston 21 and the second housing cover 26 from its maximum volume to its minimum volume according to the FIGS. 2 and 3 reduced.

Gattungsgemäßer Stand der Technik ist bekannt aus
Weiterer Stand der Technik ist bekannt aus
Damit nach dem Öffnen des mit dem Türschließer versehenen Türflügels die zuvor gespannte Schließerfeder über den Federkolben und die federkolbenseitige Rolle eine Drehung der Schließerwelle entgegen der Drehöffnungsrichtung und somit ein selbsttätiges Schließen des Türflügels bewirken kann, muss die federkolbenseitige Rolle an der Federkolben-Antriebskontur der herzförmigen Scheibe diesseits der Herzspitze abgestützt sein. Diese Bedingung ist aber nur dann erfüllt, wenn der Öffnungswinkel, über welchen der mit dem Türschließer versehene Türflügel geöffnet wird, kleiner als 180° ist. Bei größeren Türöffnungswinkeln würde die federkolbenseitige Rolle die Herzspitze in Richtung auf die Dämpfungskolben-Antriebskontur überfahren. Bei einer Einleitung der von der Schließerfeder ausgeübten Schließkraft jenseits der Herzspitze könnte die bei der Öffnungsbewegung des Türflügels gespannte Schließerfeder die Schließerwelle aber nicht entgegen der Drehöffnungsrichtung drehen und somit den Türflügel nicht schließen.Thus, after opening the provided with the door closer door, the previously tensioned closing spring on the spring piston and the spring piston side roller rotation of the closer shaft against the rotational opening direction and thus an automatic closing of the door can cause the spring piston side roller on the spring piston drive contour of the heart-shaped disc be supported on this side of the heart. However, this condition is only fulfilled if the opening angle over which the door leaf provided with the door is opened is less than 180 °. For larger door opening angles, the spring-piston-side roller would override the apex toward the damping piston drive contour. Upon initiation of the closing force exerted by the closing spring beyond the apex of the heart, the closing spring which is tensioned during the opening movement of the door leaf could not turn the closer shaft counter to the direction of rotation opening and thus not close the door leaf.
Der Türöffnungswinkel, bei welchem der vorbekannte Türschließer eine selbsttätige Schließbewegung bewirken kann, ist dementsprechend begrenzt. Von Vorteil ist der vorbekannte Türschließer allerdings insofern, als die Kraftübertragung zwischen der herzförmigen Scheibe und den daran abgestützten kolbenseitigen Rollen weitestgehend längs der Mittelebene des Türschließers erfolgt und folglich die Rollenachsen längs der Mittelebene des Türschließers angeordnet sind. Aufgrund dieser Anordnung der Rollenachsen ergibt sich zum einen eine schlanke Bauweise des Türschließers. Außerdem werden die zwischen der herzförmigen Scheibe und dem Federkolben sowie dem Dämpfungskolben des vorbekannten Türschließers wirksamen Kräfte symmetrisch in den Federkolben und den Dämpfungskolben eingeleitet. Dadurch wiederum werden auf den Federkolben und den Dämpfungskolben wirkende Kippmomente vermieden, in Folge derer die Reibung zwischen dem Federkolben und dem Dämpfungskolben einerseits und dem die Kolben führenden Türschließergehäuse andererseits erhöht wäre.The door opening angle at which the previously known door closer can effect an automatic closing movement is accordingly limited. The advantage of the known door closer, however, insofar as the power transmission between the heart-shaped disc and the piston-side rollers supported thereon is largely along the median plane of the door closer and consequently the roller axes are arranged along the median plane of the door closer. Due to this arrangement of the roller axes results on the one hand a slim design of the door closer. In addition, the effective between the heart-shaped disc and the spring piston and the damping piston of the prior art door closer forces are introduced symmetrically into the spring piston and the damping piston. In turn, acting on the spring piston and the damping piston tilting moments are avoided, as a result of which the friction between the spring piston and the damping piston on the one hand and the piston leading door closer housing on the other hand would be increased.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Stand der Technik dahingehend weiterzubilden, dass auch große Türöffnungswinkel, insbesondere Türöffnungswinkel von wenigstens 180°, bei gleichzeitig schlanker Türschließerbauweise bewältigt werden können.The object of the present invention is to develop the prior art to the effect that even large door opening angle, in particular door opening angle of at least 180 °, can be mastered with a slim door closer construction.
Erfindungsgemäß gelöst wird diese Aufgabe durch den Türschließer nach Anspruch 1.This object is achieved according to the invention by the door closer according to
Im Falle des Anspruchsgegenstands sind die Federkolben-Antriebskontur und die Dämpfungskolben-Antriebskontur längs der Konturdrehachse gegeneinander versetzt angeordnet. Gleichzeitig verlaufen die Federkolben-Antriebskontur und die Dämpfungskolben-Antriebskontur erfindungsgemäßer Türschließer mit gegenseitiger Überdeckung ihrer Umfangswinkel um die Konturdrehachse. Der gegenseitige Versatz der Federkolben-Antriebskontur und der Dämpfungskolben-Antriebskontur längs der Konturdrehachse schafft die Voraussetzung dafür, dass sowohl die Federkolben-Antriebskontur als auch die Dämpfungskolben-Antriebskontur in Umfangsrichtung um die Konturdrehachse über einen Umfangswinkel von mehr als 180° reichen können. Eine derart "lange" Federkolben-Antriebskontur bietet auch noch bei Öffnungswinkeln von 180° und mehr die Möglichkeit, die von der sich entspannenden Schließerfeder ausgeübte Kraft in eine Schließbewegung der Schließerwelle umzusetzen. Gleichzeitig gewährleistet die zur Verfügung stehende Länge der Dämpfungskolben-Antriebskontur dass die Dämpfungskolben-Antriebskontur während der gesamten Schließbewegung in einem die Schließbewegung dämpfenden Sinne wirksam sein kann. Dabei kann die Krafteinleitung an der Federkolben-Antriebskontur und/oder an der Dämpfungskolben-Antriebskontur an Stellen erfolgen, die gemeinsam mit der Konturdrehachse längs der Mittelebene des Türschließers liegen. Im Falle der Erfindung kann demnach eine Schließbewegung ausgehend von einem großen Tür-Öffnungswinkel, insbesondere ausgehend von einem Türöffnungswinkel von 180° und mehr bewirkt werden, ohne dass zu diesem Zweck die Kraftübertragung an der Federkolben-Antriebskontur und/oder an der Dämpfungskolben-Antriebskontur in erheblichem Umfang seitlich gegen die Mittellinie des Türschließers versetzt erfolgen müsste. Nachdem ein derartiger seitlicher Versatz verzichtbar ist, können erfindungsgemäße Türschließer schmal und folglich schlank bauen.In the case of the claim, the spring piston drive contour and the damping piston drive contour along the contour axis of rotation are offset from each other. At the same time, the spring piston drive contour and the damping piston drive contour of the door closer according to the invention extend with mutual overlap of their circumferential angles about the contour axis of rotation. The mutual offset of the spring piston drive contour and the damping piston drive contour along the contour axis of rotation creates the prerequisite that both the spring piston drive contour and the damping piston drive contour in the circumferential direction can extend around the contour axis of rotation over a circumferential angle of more than 180 °. Such a "long" spring piston drive contour offers even at opening angles of 180 ° and more the ability to implement the force exerted by the relaxing closing spring force in a closing movement of the closer shaft. At the same time, the available length of the damping piston drive contour ensures that the damping piston drive contour can be effective during the entire closing movement in a sense that damps the closing movement. In this case, the force can be applied to the spring piston drive contour and / or on the damping piston drive contour at locations that lie together with the contour axis of rotation along the median plane of the door closer. In the case of the invention, therefore, a closing movement can be effected starting from a large door opening angle, in particular starting from a door opening angle of 180 ° and more, without the force transmission to the spring piston drive contour and / or to the damping piston drive contour for this purpose considerable extent must be offset laterally against the center line of the door closer. After such a lateral offset is dispensable, door closers according to the invention can build narrow and consequently slim.
Besondere Ausführungsarten des Türschließers nach Anspruch 1 ergeben sich aus den abhängigen Ansprüchen 2 bis 8.Particular embodiments of the door closer according to
Gemäß Anspruch 2 sitzen die Federkolben-Antriebskontur und die Dämpfungskolben-Antriebskontur in bevorzugter Ausgestaltung der Erfindung unmittelbar auf der Schließerwelle.According to
Gemäß Anspruch 3 zeichnet sich eine bevorzugte Erfindungsbauart dadurch aus, dass die gegenseitige Beaufschlagung der Federkolben-Antriebskontur und des Federkolbens und/oder die gegenseitige Beaufschlagung der Dämpfungskolben-Antriebskontur und des Dämpfungskolbens kolbenseitig symmetrisch erfolgt. Aufgrund der Symmetrie der Krafteinleitung werden auf den Federkolben und/oder den Dämpfungskolben wirkende Kippmomente vermieden.According to
Gemäß Anspruch 4 ist in weiterer vorteilhafter Ausgestaltung der Erfindung vorgesehen, dass die Krafteinleitung zwischen der Federkolben-Antriebskontur und dem Federkolben und/oder der Dämpfungskolben-Antriebskontur und dem Dämpfungskolben über eine kolbenseitige Stützrolle erfolgt, die um eine parallel zu der Konturdrehachse verlaufende Rollen-Drehachse drehbar ist. Mit der oder den kolbenseitigen Stützrollen steht eine verschleißarme und leichtgängige Möglichkeit zur Verfügung, die Geometrie der Federkolben-Antriebskontur bzw. der Dämpfungskalben-Antriebskontur in eine Bewegung des Federkolbens bzw. des Dämpfungskolbens umzusetzen.According to
Im Falle der Erfindungsbauart nach Anspruch 5 umfasst die Dämpfungskolben-Antriebskontur mehrere längs der Konturachse gegeneinander versetzt angeordnete Antriebs-Teilkonturen. In dem Bereich der gegenseitigen Überdeckung der Umfangswinkel der Federkolben-Antriebskontur und der Dämpfungskolben-Antriebskontur greift die Federkolben-Antriebskontur mit wenigstens einem höhenreduzierten Längenabschnitt in den Zwischenraum zwischen zwei einander benachbarten Antriebs-Teilkonturen der Dämpfungskolben-Antriebskontur ein. Auf diese Art und Weise steht für die Abstützung des Dämpfungskolbens an der Dämpfungskolben-Antriebskontur auch in dem Bereich der gegenseitigen Überdeckung von Federkolben-Antriebskontur und Dämpfungskolben-Antriebskontur eine breite Basis zur Verfügung. Die Abstützung des Dämpfungskolbens erfolgt dabei beidseits des zwischen den Antriebs-Teilkonturen der Dämpfungskolben-Antriebskontur angeordneten höhenreduzierten Abschnittes der Federkolben-Antriebskontur. Durch diese symmetrische Krafteinleitung werden senkrecht zu der Konturdrehachse wirksame Kippmomente vermieden.In the case of Erfindungsbauart according to
Entsprechend stellen sich die Verhältnisse an dem erfindungsgemäßen Türschlie-ßer gemäß Patentanspruch 7 dar. Im Falle dieser Erfindungsbauart ist die Federkolben-Antriebskontur mehrteilig ausgebildet. Die Dämpfungskolben-Antriebskontur ist im Bereich der gegenseitigen Überdeckung der Umfangswinkel von Dämpfungskolben-Antriebskontur und Federkolben-Antriebskontur mit einem höhenreduzierten Abschnitt zwischen zwei einander benachbarten Antriebs-Teilkonturen der Federkolben-Antriebskontur angeordnet.Accordingly, the conditions on the door according to the invention ßer according to
Gemäß den Ansprüchen 6 und 8 ist eine kolbenseitige Stützrolle, die zur Abstützung des Dämpfungskolbens an der mehrteiligen Dämpfungskolben-Antriebskontur oder zur Abstützung des Federkolbens an der mehrteiligen Federkolben-Antriebskontur bestimmt ist, in ihrer Gestalt an die Mehrteiligkeit der Dämpfungskolben-Antriebskontur oder der Federkolben-Antriebskontur angepasst. Die kolbenseitige Stützrolle ist längs der parallel zu der Konturdrehachse verlaufenden Rollen-Drehachse unter Ausbildung von Zwischenräumen zwischen einander benachbarten axialen Rollenabschnitten gegliedert. Rollt die kolbenseitige Stützrolle in dem Bereich der gegenseitigen Überdeckung der Umfangswinkel von Dämpfungskolben-Antriebskontur und Federkolben-Antriebskontur ab, so liegt der Zwischenraum zwischen den einander benachbarten Rollenabschnitten auf Höhe des zwischen zwei Antriebs-Teilkonturen eingreifenden höhenreduzierten Abschnitts der Federkolben-Antriebskontur oder der Dämpfungskolben-Antriebskontur. Infolgedessen kann die Federkolben-Antriebskontur bzw. die Dämpfungskolben-Antriebskontur auch im Bereich der gegenseitigen Überdeckung ihrer Umfangswinkel annähernd beliebig und nur abgestimmt auf den von ihr zu gewährleistenden Momentverlauf gestaltet sein. Insbesondere kann die betreffende Antriebskontur im Bereich der gegenseitigen Überdeckung der Umfangswinkel von Dämpfungskolben-Antriebskontur und Federkolben-Antriebskontur in radialer Richtung der Konturachse gegenüber den ihr benachbarten Antriebs-Teilkonturen vorstehen.According to

Ebenso wie der Federkolben 13 ist auch der Dämpfungskolben 21 an der Innenwand des Türschließergehäuses 2 in Richtung des Doppelpfeils 17 verschiebbar geführt. Die dämpfungskolbenseitige Stützrolle 22 ist an der von der Rückstellfeder 23 abliegenden Seite des Dämpfungskolbens 21 um eine parallel zu der Achse 8 der Schließerwelle 7 verlaufende Rollen-Drehachse 25 drehbar gelagert. Auch die geometrische Achse der Rollen-Drehachse 25 liegt in der Längs-Mittelebene des Türschließergehäuses 2.Like the
Unter der Wirkung der zwischen dem Dämpfungskolben 21 und einem zweiten Gehäusedeckel 26 des Türschließergehäuses 2 gespannten Rückstellfeder 23 liegt die dämpfungskolbenseitige Stützrolle 22 an der Dämpfungskolben-Antriebskontur 24 an.Under the action of the tensioned between the damping

Der Dämpfungskolben 21 an der dem Federkolben 13 gegenüberliegenden Seite der Schließerwelle 7 befindet sich entlang der Längs-Mittelebene des Türschließergehäuses 2 in seiner schließerwellenfernen Endposition. Die Rückstellfeder 23 ist zwischen dem Dämpfungskolben 21 und dem zweiten Gehäusedeckel 26 des Türschließergehäuses 2 gestaucht und drückt folglich den Dämpfungskolben 21 sowie die dämpfungskolbenseitige Stützrolle 22 in Richtung auf die Achse 8 der Schließerwelle 7. Ein Gehäuseraum 31 zwischen dem zweiten Gehäusedeckel 26 und dem Dämpfungskolben 21 weist sein minimales Volumen auf.The damping

Aufgrund der Drehbewegung der Federkolben-Antriebskontur 15 in Drehöffnungsrichtung 32 rollt die federkolbenseitige Stützrolle 14 auf der Federkolben-Antriebskontur 15 ab. Infolge der Geometrie der Federkolben-Antriebskontur 15 verlagert sich dabei der Ort der Abstützung der federkolbenseitigen Stützrolle 14 an der Federkolben-Antriebskontur 15 von der Achse 8 der Schließerwelle 7 weg. Der Federkolben 13 wird daher durch die sich um die Achse 8 der Schließerwelle 7 drehende Federkolben-Antriebskontur 15 über die federkolbenseitige Stützrolle 14 in
In gewohnter Weise ist der Verlauf der Federkolben-Antriebskontur 15 um die Achse 8 der Schließerwelle 7 derart gewählt, dass der Achsabstand der Abstützung der federkolbenseitigen Stützrolle 14 an der Federkolben-Antriebskontur 15 mit zunehmendem Türöffnungswinkel zunimmt und folglich der Öffnungsbewegung des Türflügels 3 von der Schließerfedereinheit 10 ein mit zunehmendem Türöffnungswinkel abnehmender Widerstand entgegengesetzt wird.In the usual way, the course of the spring
Bei der Spann-Drehbewegung der Federkolben-Antriebskontur 15 in der Drehöffnungsrichtung 32 rollt die federkolbenseitige Stützrolle 14 zunächst auf einem um die Achse 8 der Schließerwelle 7 verlaufenden Umfangsabschnitt der Federkolben-Antriebskontur 15 ab, deren Höhe längs der Achse 8 der Schließerwelle 7 der Höhe der federkolbenseitigen Stützrolle 14 in Richtung der Rollen-Drehachse 18 entspricht. Mit Erreichen des in
Mit der Drehbewegung der Schließerwelle 7 und der Federkolben-Antriebskontur 15 in der Drehöffnungsrichtung 32 geht eine gleichgerichtete Drehbewegung der Dämpfungskolben-Antriebskontur 24 einher. Dabei rollt die dämpfungskolbenseitige Stützrolle 22 mit den Rollenabschnitten 29, 30 auf den Antriebs-Teilkonturen 27, 28 der Dämpfungskolben-Antriebskontur 24 ab.

Mit der Drehbewegung der Federkolben-Antriebskontur 15 entgegen der Drehöffnungsrichtung 32 verbunden ist eine gleichgerichtete Drehbewegung der Dämpfungskolben-Antriebskontur 24 um die Achse 8 der Schließerwelle 7. Die Dämpfungskolben-Antriebskontur 24 beaufschlagt dabei die dämpfungskolbenseitige Stützrolle 22 und über diese den Dämpfungskolben 21. Infolge der Geometrie der Dämpfungskolben-Antriebskontur 24, d.h. infolge der mit der fortschreitenden Schließbewegung des Türflügels 3 verbundenen Zunahme des Achsabstandes der Abstützung der dämpfungskolbenseitigen Stützrolle 22 an der Dämpfungskolben-Antriebskontur 24, bewegt sich der Dämpfungskolben 21 aus seiner schließerwellennahen Position zurück in seine Ausgangsposition gemäß den
Sowohl die Wirkungslinie der zwischen der federkolbenseitigen Stützrolle 14 und dem Federkolben 13 übertragenen Kräfte als auch die Wirkungslinie der zwischen der dämpfungskolbenseitigen Stützrolle 22 und dem Dämpfungskolben 21 übertragenen Kräfte verläuft weitestgehend entlang der Längs-Mittelebene des Türschließergehäuses 2, die eine Symmetrieebene des Federkolbens 13 und des Dämpfungskolbens 21 bildet. Aufgrund der symmetrischen Krafteinleitung wird eine Schrägstellung des Federkolbens 13 und des Dämpfungskolbens 21 im Innern des Türschließergehäuses 2 und eine damit verbundenen Erhöhung der Reibung zwischen dem Federkolben 13 und dem Dämpfungskolben 21 einerseits und der Innenwand des Türschließergehäuses 2 andererseits vermieden. Auf diese Art und Weise wird der Verschleiß an den beteiligten Türschließerkomponenten minimiert und ein hoher Wirkungsgrad des Schließerantriebes 6 gewährleistet.
