Definitions
- the invention relates to a cam mechanism based on a door closer.
- Door closers with cam mechanism typically have a Hubkurvenin rotatably mounted on an output shaft, which has a drainage surface on which a pressure roller unrolled pressed due to a closing spring.
- the Hubkurvention seen in the direction of a longitudinal extension of the output shaft of the door closer may have a symmetrical or asymmetrical cross-sectional shape.
- the pressure roller is mounted so that it can move on the Hubkurvenis to and from her. The movement takes place in the direction of the axis of rotation of the output shaft and away from it.
- the torque curve is determined by the shape of the respective running surface of the Hubkurvenin. This means that the cam disc must be specially designed, ie designed, for each application.
- asymmetric cam discs have been developed whose two drainage surface halves are designed for one operating mode.
- the course of the respective torque curve defined by the shape of the run-off surfaces can not be changed.
- a door provided with a door closer door are provided with a fire protection function, are in a predetermined first opening angle range (about 0 ° - 4 °) of a rotary wing and in a predetermined second opening angle range (about 88 ° - 92 °) of the rotary vane torques permitted only within predetermined limits.
- a predetermined first opening angle range about 0 ° - 4 °
- a predetermined second opening angle range about 88 ° - 92 °
- the object of the invention is to provide a door closer, which can be manufactured inexpensively adapted to the particular application or even adapted or converted in the assembled state to the particular application.
- a door closer has a pressure roller, which rolls pressed against a cam disc of the door closer.
- the Hubkurvenin is arranged rotatably on an output shaft.
- the pressure roller is arranged with respect to an axial center of the output shaft so that the pressure roller is moved along a path upon opening or closing of a coupled with the output shaft rotary vane.
- Characterized in that the web passes by the axial center of the output shaft, and due to the design of the running surface of HubkurvenIO is at a respective opening angle of the rotary vane at different modes of the door closer to the output shaft in each case a very similar or identical torque. Ie. in one mode a curve of a voltage applied to the rotary vane, dependent on the opening angle of the rotary vane torque curve is achieved, which is identical or very similar to a torque curve in another mode.
- the torque curve is a characteristic of a voltage applied to the output shaft of the door closer torque in dependence on the opening angle of the rotary wing.
- the advantage is that not only is the torque variable in proportion, but it is also possible to change the shape of the torque curve during a movement, i. H. a closing movement of a rotary wing, despite using a Hubkurvenectomy with one and the same shape to adapt to the particular application.
- these operating modes include slide rail operation and normal or scissors linkage operation, and preferably additionally parallel linkage operation.
- the described torque curve approximation results in particular in a lintel mounting of the door closer according to the invention in slide rail operation on a tape opposite side or in normal linkage operation on a hinge side.
- the same effect results in particular in a door leaf assembly of the door closer according to the invention Sliding rail operation on the belt side or in normal linkage operation on the opposite side of the belt.
- the door closer is also applicable to both DIN-right and DIN-left swing doors.
- the housing in the region of the drive shaft ends in each case has a passage opening, which is optionally provided by means of a cover cap, so that the unused end of the output shaft is concealed to the outside.
- the pressure roller is not fixed in relation to the Hubkurvenin in their position. Ie. during a rotation of the Hubkurvenin this moves the pressure roller to a predetermined position. The position reached then corresponds to the position at which the desired torque curve is achieved. Preferably, the adjustment takes place in a symmetrical Hubkurvenization with respect to the axis of symmetry. This can be done by the pressure roller is arranged displaceably in a direction transversely or at an angle between 0 ° and less than 90 ° to the above-described movement path of the pressure roller.
- the invention provides, vorzuvercard the Hubkurvenis. This makes it possible to match the torque at an opening angle of 0 ° in the aforementioned modes to each other.
- the Hubkurvention is symmetrical and preferably has a heart-shaped cross-sectional area. This has cost advantages compared to an asymmetric cam disc. On the one hand, the shape of only one half of the running surface of the Hubkurvenin to calculate and thus construct. Furthermore, fewer different drain surface shapes are required, which reduces the variety of Hubkurveninn to be used and thus to manufacturing tools.
- the door closer according to the invention is designed so that the direction of the movement path of the pressure roller in the assembled state of the door closer can be adjusted. This makes it possible, the door closer in the assembled state, d. H. on site, still to adapt to any peculiarities of the opening or closing process. In addition, this makes it possible to provide the door closer with a new function in retrospect or, for example, switch from slide rail operation to normal linkage or parallel linkage operation or vice versa.
- the arrangement can be mounted as a whole displaceable.
- Figure 1A is schematically illustrated, which course has a force translation i cam in a symmetrically shaped Hubkurvenrion a conventional cam mechanism 'in response to an opening angle ⁇ of a rotary wing.
- a force transmission ratio i cam At an opening angle ⁇ of 0 ° is the force transmission ratio i cam is substantially equal to 1, after which the force transmission ratio i cam falls within a relatively small opening angle range relatively steeply to a lower minimum value and then rises again.
- a force transmission curve according to the left-hand diagram in FIG Figure 1C , Unlike the in FIG. 1B shown power transmission curve is the force transmission i cam here at an opening angle ⁇ of 0 ° much higher, it may have a value between 3-7 or even tend to near infinity. After that, the force transmission i cam falls off similar to an upwardly open parabola. The negative increase in the power transmission curve is steadily decreasing. The resulting torque curve is right in Figure 1C shown.
- the torque M is at the beginning, ie at an opening angle ⁇ of 0 °, relatively high and is about 3 - 4 Nm. Thereafter, the torque falls very sharply within a very small opening angle range and approaches a lower, minimum value.
- the setting of a door rest position opening angle ⁇ in a range of about 0 °
- Small changes in the opening angle ⁇ cause a large change in the torque M.
- the pressure roller is movable with respect to the cam disc along a path in which a direction of movement of the pressure roller does not intersect at any point of the track the axial center of the cam disc.
- FIG. 1D two diagrams are shown, indicating the torque curves for a cam mechanism with conventionally arranged pressure roller in Gleitschienen- or normal rod operation.
- the respective upper characteristic curve indicates the torque curve during an opening process
- the lower characteristic curve shows the torque curve during a closing operation.
- the differences between these characteristics are due to the fact that the opening takes place against the force of a closing spring.
- the torque M at an opening angle ⁇ of 0 ° when opening in normal linkage operation is much higher (about 162 Nm) than in slide rail operation (about 111 Nm).
- closing the torque M is at an opening angle ⁇ of 0 ° in normal linkage operation about 81 Nm and at Gleitschienen-operation about 55 Nm.
- the differences of the torques M in the two operating modes to each other consequently amount to about 51 Nm or 26 Nm. Furthermore, the torque curve at normal start-up operation falls significantly steeper at the beginning than the torque curve at slide rail operation. The torque curves thus have different gradients.
- Figure 1E shows torque curves, which are achieved when a pressure roller is arranged according to the invention.
- the torque M In normal linkage operation, the torque M at an opening angle ⁇ of 0 ° when opening is about 142 Nm and when closing about 70 Nm.
- the torque M In slide rail operation, the torque M at an opening angle ⁇ of 0 ° when opening is about 143 Nm and when closing about 71 Nm.
- the differences of the torques M in the two operating modes to each other are only about 1 Nm, thus are in a range between 0.7% and 1.5% with respect to a respective reference torque in one mode.
- the torque curve in normal rod operation at an opening angle ⁇ of 0 ° does not drop as steep as in Figure 1E , Rather, the shapes of the torque curves, so the torque curves in the two modes are approximated.
- the torques M in the mentioned modes are identical or very similar at a respective opening angle ⁇ .
- the difference of the torque values at a respective opening angle ⁇ in the operating modes relative to one another preferably lies in a range of at most 10%, preferably 5% or less with respect to one of the applied torques in one of the operating modes.
- the torque M at an opening angle ⁇ of 0 ° can not only be increased. It is also possible to make the torque M at an opening angle ⁇ of 0 ° lower than the average torque applied during a moving operation of a rotary vane.
- a torque curve shown in the diagram by means of a solid line is achieved, in both directions of rotation of a cam disc 103 indicated on the bottom left.
- the pressure roller 101 is arranged in such a way that it can move through a direction of movement R B defined trajectory of the pressure roller 101, the axial center of an output shaft 104 intersects.
- the pressure roller is thus centric with respect to the output shaft 104, a so-called eccentricity e is equal to 0.
- An offset of the pressure roller causes when rotating the Hubkurvenement 103 along a first, according to Figure 1F upper run-surface section of Hubkurvenement 103 in a direction which is indicated by a dashed arrow, a torque curve according to the dashed line in the graph shown characteristic.
- a torque M is increased at an opening angle ⁇ of 0 °.

Abstract
Description
Die Erfindung betrifft einen auf einem Nockenmechanismus basierenden Türschließer.The invention relates to a cam mechanism based on a door closer.
Türschließer mit Nockenmechanismus weisen typischerweise eine auf einer Abtriebswelle drehfest angeordnete Hubkurvenscheibe auf, die eine Ablauffläche aufweist, auf der eine Andrückrolle aufgrund einer Schließerfeder angepresst abrollt.Door closers with cam mechanism typically have a Hubkurvenscheibe rotatably mounted on an output shaft, which has a drainage surface on which a pressure roller unrolled pressed due to a closing spring.
Durch die Form der Ablauffläche wird der Verlauf des an dem angetriebenen Drehflügel anliegenden Drehmoments während einer Schließbewegung, d. h. die resultierende Drehmomentkurve, bestimmt.Due to the shape of the drainage surface, the course of the torque applied to the driven rotary vane during a closing movement, i. H. the resulting torque curve is determined.
Die Hubkurvenscheibe kann in Richtung einer Längserstreckung der Abtriebswelle des Türschließers gesehen eine symmetrische oder asymmetrische Querschnittsform aufweisen.The Hubkurvenscheibe seen in the direction of a longitudinal extension of the output shaft of the door closer may have a symmetrical or asymmetrical cross-sectional shape.
Die Andrückrolle ist so gelagert, dass sie sich auf die Hubkurvenscheibe zu und von ihr weg bewegen kann. Die Bewegung erfolgt in Richtung zur Rotationsachse der Abtriebswelle hin und von ihr weg.The pressure roller is mounted so that it can move on the Hubkurvenscheibe to and from her. The movement takes place in the direction of the axis of rotation of the output shaft and away from it.
Die Drehmomentkurve ist durch die Form der jeweiligen Ablauffläche der Hubkurvenscheibe vorgegeben. Dies bedeutet, dass die Hubkurvenscheibe für jeden Einsatzfall speziell ausgebildet, d. h. konstruiert werden muss,The torque curve is determined by the shape of the respective running surface of the Hubkurvenscheibe. This means that the cam disc must be specially designed, ie designed, for each application.
Im Querschnitt symmetrisch ausgebildete Hubkurvenscheiben bewirken bei Gleitschienen-Betrieb eine andere Drehmomentkurve als bei einem Normal- oder Scherengestänge sowohl im Betrag als auch im Verlauf.In cross-section symmetrically shaped Hubkurvenscheiben cause slide rail operation a different torque curve than in a normal or scissor linkage both in magnitude and in the course.
Um ein und denselben Türschließer für beide Betriebsarten einsetzen zu können, müssen die Drehmomentkurven jedoch im Wesentlichen übereinstimmen.However, in order to use one and the same door closer for both modes of operation, the torque curves must be substantially the same.
Zu diesem Zweck wurden asymmetrische Hubkurvenscheiben entwickelt, deren zwei Ablaufflächenhälften auf jeweils eine Betriebsart hin ausgelegt sind. Der durch die Form der Ablaufflächen definierte Verlauf der jeweiligen Drehmomentkurve ist nicht veränderbar.For this purpose, asymmetric cam discs have been developed whose two drainage surface halves are designed for one operating mode. The course of the respective torque curve defined by the shape of the run-off surfaces can not be changed.
Soll nun eine mit einem Türschließer versehene Tür mit einer Brandschutzfunktion versehen werden, sind in einem vorbestimmten ersten Öffnungswinkel-Bereich (ca. 0° - 4°) eines Drehflügels und in einem vorbestimmten zweiten Öffnungswinkel-Bereich (ca. 88° - 92°) des Drehflügels Drehmomente nur innerhalb vorbestimmter Grenzen zulässig. Außerdem gibt es ein minimales Drehmoment, das über den gesamten Öffnungswinkel-Bereich des Drehflügels nicht unterschritten werden darf.If now a door provided with a door closer door are provided with a fire protection function, are in a predetermined first opening angle range (about 0 ° - 4 °) of a rotary wing and in a predetermined second opening angle range (about 88 ° - 92 °) of the rotary vane torques permitted only within predetermined limits. In addition, there is a minimum torque that must not be exceeded over the entire opening angle range of the rotary wing.
Die einzig bekannte Möglichkeit, das Drehmoment am Drehflügel zu verändern, sind Mechanismen zur Einstellung der Vorspannung der Schließerfeder. Solche Mechanismen umfassen zumeist eine Einstellschraube, mittels der die Position eines Schließerfederanschlags verändert werden kann. Damit lässt sich die Größe des Drehmoments in einem im Wesentlichen konstanten Verhältnis verändern. Die Form der Drehmomentkurve bleibt unverändert.The only known way to change the torque on the rotary wing are mechanisms for adjusting the bias of the closing spring. Such mechanisms usually comprise an adjusting screw by means of which the position of a closer spring stop can be changed. Thus, the size of the torque can be changed in a substantially constant ratio. The shape of the torque curve remains unchanged.
Sind ein Drehmoment bei einem Öffnungswinkel von 0°, d. h, bei geschlossenem Drehflügel, zu hoch und ein Enddrehmoment, d. h. ein Drehmoment bei einem maximalen Öffnungswinkel von beispielsweise 90 - 100°, nur geringfügig größer als ein zulässiges minimales Drehmoment, könnte mittels einer Verstellung der Schließerfeder-Vorspannung zwar das Drehmoment bei einem Öffnungswinkel von 0° verringert werden, gleichzeitig würde aber das Enddrehmoment unter das zulässige minimale Drehmoment fallen. Ein Umstellen auf eine Brandschutzfunktion wäre somit unmöglich. Eine Ersetzung eines Türschließers durch einen komplett neuen führt zu enormen Kosten.Are a torque at an opening angle of 0 °, d. h, with the revolving wing closed, too high and a final torque, d. H. a torque at a maximum opening angle of for example 90-100 °, only slightly larger than a permissible minimum torque, could be reduced by means of an adjustment of the closing spring bias while the torque at an opening angle of 0 °, but at the same time the final torque below the allowable minimal torque fall. Switching to a fire protection function would therefore be impossible. Replacing a door closer with a completely new one adds up to enormous costs.
Aufgabe der Erfindung ist es, einen Türschließer zu schaffen, der kostengünstig an den jeweiligen Einsatzfall angepasst hergestellt bzw. im Montagezustand selbst an den jeweiligen Einsatzfall angepasst oder umgestellt werden kann.The object of the invention is to provide a door closer, which can be manufactured inexpensively adapted to the particular application or even adapted or converted in the assembled state to the particular application.
Die Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.The object is solved by the subject matter of
Erfindungsgemäß weist ein Türschließer eine Andrückrolle, die auf einer Hubkurvenscheibe des Türschließers angepresst abrollt. Die Hubkurvenscheibe ist auf einer Abtriebswelle drehfest angeordnet. Die Andrückrolle ist in Bezug auf einen axialen Mittelpunkt der Abtriebswelle so angeordnet, dass die Andrückrolle bei einem Öffnen oder Schließen eines mit der Abtriebswelle gekoppelten Drehflügels entlang einer Bahn bewegt wird. Dadurch, dass die Bahn an dem axialen Mittelpunkt der Abtriebswelle vorbeiläuft, und aufgrund der Gestaltung der Ablauffläche der Hubkurvenscheibe liegt bei einem jeweiligen Öffnungswinkel des Drehflügels bei verschiedenen Betriebsarten des Türschließers an der Abtriebswelle jeweils ein sehr ähnliches oder identisches Drehmoment an. D. h. bei einer Betriebsart wird ein Verlauf eines am Drehflügel anliegenden, vom Öffnungswinkel des Drehflügels abhängiger Drehmomentverlauf erzielt, der identisch oder sehr ähnlich einem Drehmomentverlauf bei einer anderen Betriebsart ist.According to the invention, a door closer has a pressure roller, which rolls pressed against a cam disc of the door closer. The Hubkurvenscheibe is arranged rotatably on an output shaft. The pressure roller is arranged with respect to an axial center of the output shaft so that the pressure roller is moved along a path upon opening or closing of a coupled with the output shaft rotary vane. Characterized in that the web passes by the axial center of the output shaft, and due to the design of the running surface of Hubkurvenscheibe is at a respective opening angle of the rotary vane at different modes of the door closer to the output shaft in each case a very similar or identical torque. Ie. in one mode a curve of a voltage applied to the rotary vane, dependent on the opening angle of the rotary vane torque curve is achieved, which is identical or very similar to a torque curve in another mode.
Der Drehmomentverlauf ist dabei eine Kennlinie eines an der Abtriebswelle des Türschließers anliegenden Drehmoments in Abhängigkeit vom Öffnungswinkel des Drehflügels.The torque curve is a characteristic of a voltage applied to the output shaft of the door closer torque in dependence on the opening angle of the rotary wing.
Der Vorteil ist, dass nicht nur das Drehmoment im Verhältnis veränderbar ist, sondern es ferner möglich ist, die Form der Drehmomentkurve während einer Bewegung, d. h. einer Schließbewegung eines Drehflügels, trotz Einsatzes einer Hubkurvenscheibe mit ein und derselben Form an den jeweiligen Einsatzfall anzupassen.The advantage is that not only is the torque variable in proportion, but it is also possible to change the shape of the torque curve during a movement, i. H. a closing movement of a rotary wing, despite using a Hubkurvenscheibe with one and the same shape to adapt to the particular application.
Dadurch ist ein einziger Türschließer in verschiedenen Betriebsarten einsetzbar. Diese Betriebsarten umfassen erfindungsgemäß GleitschienenBetrieb und Normal- bzw. Scherengestänge-Betrieb und vorzugsweise zusätzlich Parallelgestänge-Betrieb.As a result, a single door closer can be used in different modes. According to the invention, these operating modes include slide rail operation and normal or scissors linkage operation, and preferably additionally parallel linkage operation.
Es hat sich gezeigt, dass aufgrund der Neuanordnung der Andrückrolle die Drehmomentkurven bei Gleitschienen-Betrieb und bei Normalgestänge-Betrieb insbesondere bei Nutzung einer symmetrisch gestalteten Hubkurvenscheibe aneinander angeglichen werden können.It has been shown that due to the rearrangement of the pressure roller, the torque curves in slide rail operation and normal rod operation, especially when using a symmetrically designed Hubkurvenscheibe can be matched to each other.
Die beschriebene Drehmomentkurven-Angleichung ergibt sich insbesondere bei einer Sturzmontage des erfindungsgemäßen Türschließers bei Gleitschienen-Betrieb auf einer Bandgegenseite oder bei Normalgestänge-Betrieb auf einer Bandseite. Die gleiche Wirkung ergibt sich insbesondere bei einer Türblattmontage des erfindungsgemäßen Türschließers bei Gleitschienen-Betrieb auf der Bandseite oder bei Normalgestänge-Betrieb auf der Bandgegenseite.The described torque curve approximation results in particular in a lintel mounting of the door closer according to the invention in slide rail operation on a tape opposite side or in normal linkage operation on a hinge side. The same effect results in particular in a door leaf assembly of the door closer according to the invention Sliding rail operation on the belt side or in normal linkage operation on the opposite side of the belt.
Zudem ist eine Anpassung an verschiedene EN-Klassen möglich. D. h. ein und derselbe Türschließer kann für verschiedenartige Schließszenarien und mit verschiedenen Drehflügelgewichten verwendet werden, was weniger verschiedenartig ausgebildete Türschließer erforderlich macht. Dies führt zu einer Senkung von Herstellungskosten.In addition, adaptation to different EN classes is possible. Ie. one and the same door closer can be used for various closing scenarios and with different blade weights, which requires less diversely designed door closers. This leads to a reduction in manufacturing costs.
Zudem ist es möglich, nicht nur den Grad des Drehmomentanstiegs zu verändern sondern gegebenenfalls sogar den Anstieg so zu verändern, dass das Drehmoment beispielsweise zu Beginn nicht abfällt sondern (von einem geringeren Drehmoment bei einem Öffnungswinkel von 0° an) ansteigt.In addition, it is possible to change not only the degree of torque increase but possibly even to change the increase so that the torque, for example, does not drop at the beginning but increases (from a lower torque at an opening angle of 0 °).
Außerdem kann durch solch eine Verstellung ein Sturzausgleich erfolgen, sodass eine Montage sowohl auf Bandseite als auch auf Bandgegenseite möglich ist. Ferner sind derartig ausgebildete Türschließer bei verschiedenen Türgeometrien einsetzbar.In addition, can be done by such an adjustment, a fall compensation, so that a mounting on both the hinge side and on the opposite hinge side is possible. Furthermore, such trained door closers can be used with different door geometries.
Sind die Abtriebswelle und das Gehäuse des erfindungsgemäßen Türschließers so gestaltet, dass die Abtriebswelle an beiden Enden mit einem Drehflügel wirkverbunden werden kann, ist der Türschließer ferner sowohl an DIN-rechten als auch an DIN-linken Drehflügeltüren einsetzbar. Dazu weist das Gehäuse im Bereich der Antriebswellen-Enden jeweils eine Durchgangsöffnung auf, die ggf, mittels einer Abdeckkappe versehen ist, sodass das nicht verwendete Ende der Abtriebswelle nach außen verdeckt ist.Are the output shaft and the housing of the door closer according to the invention designed so that the output shaft can be operatively connected at both ends with a rotary wing, the door closer is also applicable to both DIN-right and DIN-left swing doors. For this purpose, the housing in the region of the drive shaft ends in each case has a passage opening, which is optionally provided by means of a cover cap, so that the unused end of the output shaft is concealed to the outside.
Ferner kann vorgesehen sein, dass die Andrückrolle in Bezug auf die Hubkurvenscheibe in ihrer Position nicht festgelegt ist. D. h. bei einer Rotation der Hubkurvenscheibe bewegt diese die Andrückrolle bis zu einer vorbestimmten Position mit. Die erreichte Position entspricht dann der Position, bei der die gewünschte Drehmomentkurve erzielt wird. Vorzugsweise erfolgt die Verstellung bei einer symmetrischen Hubkurvenscheibe in Bezug auf deren Symmetrieachse. Dies kann dadurch erfolgen, dass die Andrückrolle in einer Richtung quer oder in einem Winkel zwischen 0° und weniger als 90° zu der vorbeschriebenen Bewegungsbahn der Andrückrolle verschiebbar angeordnet ist.Furthermore, it can be provided that the pressure roller is not fixed in relation to the Hubkurvenscheibe in their position. Ie. during a rotation of the Hubkurvenscheibe this moves the pressure roller to a predetermined position. The position reached then corresponds to the position at which the desired torque curve is achieved. Preferably, the adjustment takes place in a symmetrical Hubkurvenscheibe with respect to the axis of symmetry. This can be done by the pressure roller is arranged displaceably in a direction transversely or at an angle between 0 ° and less than 90 ° to the above-described movement path of the pressure roller.
Zusätzlich ist erfindungsgemäß vorgesehen, die Hubkurvenscheibe vorzuverdrehen. Dadurch ist es möglich, das Drehmoment bei einem Öffnungswinkel von 0° in den vorgenannten Betriebsarten aneinander anzugleichen.In addition, the invention provides, vorzuverdrehen the Hubkurvenscheibe. This makes it possible to match the torque at an opening angle of 0 ° in the aforementioned modes to each other.
Zusätzlich hat es sich beim Normalgestänge als vorteilhaft erwiesen, den Abstand des axialen Mittelpunkts der Abtriebswelle des Türschließers zum Rotationspunkt eines Drehflügels und/oder den Abstand des axialen Mittelpunkts der Abtriebswelle des Türschließers zum Anlenkpunkt des Normalgestänges am Drehflügel zu variieren. Mit größer werdendem Abstand zum Rotationspunkt des Drehflügels verändern sich der maximale Öffnungswinkel und die Hebelwirkung. Aufgrund dieser Variationen ist es möglich, die Drehmomente in einem vorbestimmten Verhältnis zu verändern. Beispielsweise können das Verhältnis von Drehmoment bei einem Öffnungswinkel von 0° zu Enddrehmoment und aufgrund der Verstellung des maximalen Öffnungswinkels die Drehmomentkurve verändert werden. Besonders vorteilhaft hat sich erwiesen, wenn der Abstand zum Anlenkpunkt des Normalgestänges gleich oder größer als der Abstand zum Rotationspunkt des Drehflügels ist.In addition, it has proven to be advantageous in the normal linkage to vary the distance of the axial center of the output shaft of the door closer to the rotation point of a rotary wing and / or the distance of the axial center of the output shaft of the door closer to the articulation point of the normal linkage on the rotary wing. With increasing distance to the rotation point of the rotary wing, the maximum opening angle and the leverage change. Due to these variations, it is possible to change the torques in a predetermined ratio. For example, the ratio of torque at an opening angle of 0 ° to end torque and due to the adjustment of the maximum opening angle, the torque curve can be changed. It has proved particularly advantageous if the distance to the articulation point of the normal linkage is equal to or greater than the distance to the rotation point of the rotary vane.
Erfindungsgemäß ist die Hubkurvenscheibe symmetrisch ausgebildet und hat vorzugsweise eine herzförmige Querschnittsfläche. Dies hat Kostenvorteile im Vergleich zu einer asymmetrischen Hubkurvenscheibe. Zum einen ist die Form nur einer Hälfte der Ablauffläche der Hubkurvenscheibe zu berechnen und damit zu konstruieren. Ferner sind weniger unterschiedliche Ablaufflächenformen erforderlich, was die Vielfalt an einzusetzenden Hubkurvenscheiben und damit an Herstellungs-Werkzeugen reduziert.According to the Hubkurvenscheibe is symmetrical and preferably has a heart-shaped cross-sectional area. This has cost advantages compared to an asymmetric cam disc. On the one hand, the shape of only one half of the running surface of the Hubkurvenscheibe to calculate and thus construct. Furthermore, fewer different drain surface shapes are required, which reduces the variety of Hubkurvenscheiben to be used and thus to manufacturing tools.
Alternativ oder zusätzlich ist der Türschließer erfindungsgemäß so gestaltet, dass die Richtung der Bewegungsbahn der Andrückrolle im Montagezustand des Türschließers eingestellt werden kann. Dadurch ist es möglich, den Türschließer auch im Montagezustand, d. h. vor Ort, noch an etwaige Besonderheiten des Öffnungs- bzw. Schließvorgangs anzupassen. Zudem ist es dadurch möglich, den Türschließer auch im Nachhinein noch mit einer neuen Funktion zu versehen oder beispielsweise von Gleitschienen-Betrieb auf Normalgestänge- oder Parallelgestänge-Betrieb oder umgekehrt umzustellen.Alternatively or additionally, the door closer according to the invention is designed so that the direction of the movement path of the pressure roller in the assembled state of the door closer can be adjusted. This makes it possible, the door closer in the assembled state, d. H. on site, still to adapt to any peculiarities of the opening or closing process. In addition, this makes it possible to provide the door closer with a new function in retrospect or, for example, switch from slide rail operation to normal linkage or parallel linkage operation or vice versa.
D. h. ein und derselbe Türschließer ist universell einsetzbar. Die Herstellungskosten werden gesenkt, da mit weniger Typen von Türschließern eine Vielfalt an Automatikfunktionen, wie beispielsweise Brandschutzfunktion, realisiert werden kann.Ie. one and the same door closer is universally applicable. The manufacturing costs are reduced because with fewer types of door closers, a variety of automatic functions, such as fire protection function, can be realized.
Alternativ oder zusätzlich ist vorgesehen, die Anordnung bestehend zumindest aus einer Andrückrolle und einer Schließerfeder rotierbar und arretierbar zu lagern, wobei der Rotationspunkt nicht der axiale Mittelpunkt der Abtriebswelle des Türschließers ist.Alternatively or additionally, it is provided to mount the arrangement consisting of at least one pressure roller and a closing spring rotatable and lockable, wherein the rotation point is not the axial center of the output shaft of the door closer.
Zusätzlich oder anstelle der Rotationslagerung kann die Anordnung insgesamt verschiebbar gelagert sein.In addition or instead of the rotary bearing arrangement, the arrangement can be mounted as a whole displaceable.

Durch das aneinander Angleichen der Drehmomentkurven ist es ferner erreicht, dass die zum Öffnen eines Drehflügels erforderliche Kraft in den Betriebsarten in etwa gleich ist.As a result, the torques M in the mentioned modes are identical or very similar at a respective opening angle φ. The difference of the torque values at a respective opening angle φ in the operating modes relative to one another preferably lies in a range of at most 10%, preferably 5% or less with respect to one of the applied torques in one of the operating modes. By matching the torque curves, it is also achieved that the force required to open a rotary vane in the operating modes is approximately the same.

Bei einem Rotieren der Hubkurvenscheibe 103 in Richtung Anschlagteil 209 wird die Andrückrolle 101 in diese Richtung gedrängt. Aufgrund der sehr starken Kraft der Schließerfeder 102 wird die Andrückrolle 101 nicht mittels der Anschlagfeder 210 in ihre Ausgangsposition zurückgedrängt. Erst bei einem Rückwärtsrotieren der nicht dargestellten Hubkurvenscheibe 103 gelangt die Andrückrolle 101 aufgrund der Form der Ablauffläche der Hubkurvenscheibe 103 und der Kraft der Schließerfeder 102 wieder in ihre Ausgangsposition.On at least one side of the

Der Laschenwagen 106 kann auch nur eine Verbindungsstange 111 umfassen. Eine Führung des Laschenwagens 106 wird mittels eines Langlochs in der Lasche 114 erreicht, mittels dessen die Lasche die Abtriebswelle 104 umgreifen oder umschließt. Auf der Abtriebswelle 104 ist vorzugsweise eine Lagerhülse mit beispielsweise einem Kugel-, Wälz- oder Gleitlager angeordnet.

Die Ausnehmung weist eine Form auf, die komplementär zu der Form des Teils der Schraube 204, 205, 212 ist, die von der Ausnehmung aufgenommen wird. Dadurch wird eine formschlüssige Verbindung zwischen Schraube 204, 205, 212 und Aufsetzteil 22 erreicht. Aufgrund des Verschraubens mit den Führungsteilen 21 wird somit die Schraube 204, 205, 212 in ihrer Verdreh-Position sicher fixiert. Die Schraube 204, 205, 212 ist weiterhin im Langloch 113 verschiebbar. Eine Bewegung der Andrückrolle 101 aufgrund einer Rotation der Hubkurvenscheibe 103 ist somit weiterhin gewährleistet.The
