Definitions
- the invention relates to a door closer according to the preamble of claim 1.
- Such a closer is known from DE-OS 33 45 004.
- predetermined strokes adapted to the opening and closing characteristics are assigned by the design of the cam tracks, the spring support member and also the damping piston depending on the door opening angle or angle of rotation.
- the cam track assigned to the fader support member permits a stroke assigned to the angle of rotation of the closer shaft.
- DE-OS 20 41 099 shows a floor door closer in which the sliding member of a second damping device is secured against rotation. This protection against rotation is realized by a stop protruding into a groove. As a result, the sliding member cannot twist during an axial movement.
- the object of the invention is to provide a door closer of the type mentioned, in which a rotation of the damping piston and the force transmission member about the longitudinal axis with respect to the cam disc is avoided, ie they must be able to move independently of one another in the axial movement. Likewise, the anti-rotation device must not have any influence on the cam disc used.
- securing means are present which prevent the damping piston and the spring support member from rotating against one another.
- the function of the door closer is in no way impaired by the attachment of the securing means.
- Two rods are used as securing means, which are advantageous on the one hand e.g. are firmly anchored in the spring support member and, on the other hand, can smoothly plunge into blind bores on the opposite side within the damping piston.
- the securing rods are arranged on each side of the closer shaft in the axial direction of the housing. This makes it possible that the locking rods are supported either on one or the other side of the closer shaft when the damping piston or the spring support member is rotated.
- a round bar can be positively and positively e.g. anchor within the spring support member or the damping piston. On the opposite side there are free bores in which these round bars can dip without friction when the door closer is actuated.
- the locking pins thus represent a rotation lock of the pistons with respect to the cam disc. This always ensures that the piston or the spring support member remain in their original position. If the spring support member or the damping piston are brought out of their original position, the rollers can no longer come into engagement with the cam disc properly. There is a pushing and rubbing, which results in increased wear of the door closer. Also, the degree of damping of the door closer is no longer correct when the damping piston or the spring support member is turned, because other forces are used within the door closer. When the spring support member is rotated, the force curve from the spring via the roller to the cam disc is significantly worse, and the required closing torques are no longer provided, which may not ensure that the door is closed securely.
- the section (1) of the door closer shown in FIG. 1 has been shown in section.
- the closer shaft (2) is located inside the housing (1).
- the cam disc (3) is non-positively and positively connected to the closer shaft.
- Both the roller (13) and the force transmission roller (14) are in contact with the cam disc (3) via spring forces that lie behind the damping piston (10) and the spring support member (20).
- the roller (13) is located within the damping piston (10) and is rotatably supported in the damping piston (10) by an axle bolt (11).
- the power transmission roller (14) is also rotatably mounted within the spring support member (20) by means of an axle bolt (12).
- a force is transmitted against the spring support member (20) via the pressure spring (15) via the force transmission roller (14) to the cam disc (3).
- a spring (21) is also located behind the damping piston (10).
- two securing rods (8) are located within the spring support member (20). These locking bars run in the longitudinal axis of the closer housing and transverse to the closer shaft (2). They are firmly connected to the spring support member (20) via a non-positive and positive connection (18). This can happen, for example, in that heavy-duty locking pins are provided as securing rods (8), which sit with a press fit in the spring support member (20). It would also be possible to press them into the damping piston (10). It is crucial for the function of the safety rods (8) that they close to the closer shaft (2) To have position. They therefore run with appropriate play directly above the cam disc curve (3) and directly past the two sides of the longitudinal axis of the closer shaft (2).
- the closer shaft extension (9) is required to support the deep groove ball bearing located in the sealing plug (6), but not shown. In the area of the security rods (8), this shaft extension is interrupted by a groove to make room for the security rods (8). This measure ensures that the spring support member (20) cannot rotate with respect to the cam disc (3). The spring support member (20) would not change its position in relation to the cam disc (3) by either a right or a left turn.
- the locking rods (8) are made long enough so that they can be immersed smoothly with a clearance fit within the damping piston (10) in two blind holes (16).
- the depth and length of the blind bores (16) are dimensioned such that a sufficiently large free space (17) remains between the inserted safety rod end (19) and the end of the blind bore (16).
- This free space (17) must be dimensioned so deep that during the longitudinal movements of the damping piston (10) and the spring support member (20) the safety rods (8) do not stop (10) within the damping piston.
- the aforementioned blind bore (16) can also be present within the spring support member (20). It is important that at least two rods are used, because if only one rod were used, the damping piston (10) and the spring support member (20) might only be secured against one direction of rotation.
- round materials have been used as securing rods (8). These round bars or pins represent an inexpensive fuse and are also easy to handle when manufacturing the door closer. Square materials or other materials can of course also be used just as well.
Abstract
Description
Die Erfindung betrifft einen Türschließer nach dem Oberbegriff des Anspruchs 1.The invention relates to a door closer according to the preamble of claim 1.
Ein derartiger Schließer ist aus der DE-OS 33 45 004 bekannt geworden. Bei Türschließern dieser Art wird durch die Gestaltung der Kurvenbahnen, dem Federstützglied und auch dem Dämpfungskolben ja nach Türöffnungswinkel bzw. Drehwinkel vorbestimmte, an die Öffnungs- und Schließcharakteristik angepaßte Hübe zugeteilt. Die dem Faderstützglied zugeordnete Kurvenbahn erlaubt einen dem Drehwinkel der Schließerwelle zugeordneten Hub.Such a closer is known from DE-OS 33 45 004. In door closers of this type, predetermined strokes adapted to the opening and closing characteristics are assigned by the design of the cam tracks, the spring support member and also the damping piston depending on the door opening angle or angle of rotation. The cam track assigned to the fader support member permits a stroke assigned to the angle of rotation of the closer shaft.
Der DE-OS 20 41 099 ist ein Bodentürschließer zu entnehmen, bei dem das Verschiebeglied einer zweiten Dämpfungsvorrichtung gegen Verdrehung gesichert ist. Diese Verdrehsicherung wird durch einen in eine Nut hineinragenden Anschlag realisiert. Dadurch kann sich das Verschiebeglied bei einer Axialbewegung nicht verdrehen.DE-OS 20 41 099 shows a floor door closer in which the sliding member of a second damping device is secured against rotation. This protection against rotation is realized by a stop protruding into a groove. As a result, the sliding member cannot twist during an axial movement.
Die Aufgabe der Erfindung besteht darin, einen Türschließer der eingangs genannten Art zu schaffen, bei dem ein Verdrehen des Dämpfungskolbens und des Kraftübertragungsgliedes um die Längsachse gegenüber der Hubkurvenscheibe vermieden wird, d.h. sie müssen sich unabhängig voneinander in der Axialbewegung verschieben lassen können. Ebenfalls darf die Verdrehsicherung keinen Einfluß auf die verwendete Hubkurvenscheibe haben.The object of the invention is to provide a door closer of the type mentioned, in which a rotation of the damping piston and the force transmission member about the longitudinal axis with respect to the cam disc is avoided, ie they must be able to move independently of one another in the axial movement. Likewise, the anti-rotation device must not have any influence on the cam disc used.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst, und zwar so, daß Sicherungsmittel vorhanden sind, die ein Verdrehen des Dämpfungskolbens und des Federstützgliedes gegeneinander vermeiden. Durch die Anbringung der Sicherungsmittel wird die Funktion des Türschließers in keiner Weise beeinträchtigt. Als Sicherungsmittel werden zwei Stäbe verwendet, die vorteilhaft einerseits z.B. im Federstützglied fest verankert sind und andererseits auf der gegenüberliegenden Seite innerhalb des Dämpfungskolbens in Sackbohrungen reibungslos eintauchen können. Die Anordnung der Sicherungsstäbe geschieht an jeder Seite der Schließerwelle in Achsrichtung des Gehäuses. Dadurch ist es möglich, daß sich bei einem Verdrehen des Dämpfungskolbens oder des Federstützgliedes die Sicherungsstäbe entweder auf der einen oder anderen Seite an der Schließerwelle abstützen.This object is achieved by the characterizing features of claim 1, in such a way that securing means are present which prevent the damping piston and the spring support member from rotating against one another. The function of the door closer is in no way impaired by the attachment of the securing means. Two rods are used as securing means, which are advantageous on the one hand e.g. are firmly anchored in the spring support member and, on the other hand, can smoothly plunge into blind bores on the opposite side within the damping piston. The securing rods are arranged on each side of the closer shaft in the axial direction of the housing. This makes it possible that the locking rods are supported either on one or the other side of the closer shaft when the damping piston or the spring support member is rotated.
Will sich entweder der Dämpfungskolben oder aber auch das Federstützglied verdrehen, so ist dieses nicht möglich, denn die Sicherungsstäbe halten den Dämpfungskolben und das Federstützglied in ihrer ursprünglich montierten Lage fest.If either the damping piston or the spring support member wants to twist, this is not possible because the locking rods hold the damping piston and the spring support member in their originally installed position.
Ein Verdrehen um die eigene Achse entweder des Dämpfungskolbens oder des Federstützgliedes ist dann möglich, wenn die Tür in eine extreme Offenstellung gebracht wird. In dieser extremen Offenlage ist es möglich, daß durch den erhöhten Federdruck z.B. das Federstützglied sich um die eigene Achse dreht. Durch diese Verdrehung ist es nicht mehr sichergestellt, daß die Andruckrolle mit der Hubkurvenscheibe sicher im Eingriff steht. Ein reibungsloser Betrieb des Türschließers ist somit nicht gewährleistet. Um jedoch einen reibungslosen Betrieb zu garantieren, werden der Dämpfungskolben und das Federstützglied gegen Verdrehung um die eigene Achse gesichert, ohne daß dadurch die Funktion des Türschließers beeinträchtigt wird.Rotation around its own axis of either the damping piston or the spring support member is possible when the door is brought into an extreme open position. In this extreme open position it is possible that, for example, the spring support member rotates about its own axis due to the increased spring pressure. This rotation no longer ensures that the pressure roller is securely engaged with the cam disc. Smooth operation of the door closer is therefore not guaranteed. However, in order to guarantee smooth operation, the damping piston and the spring support member are secured against rotation about their own axis, without this affecting the function of the door closer.
In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Gegenstandes ist es möglich, eine preiswerte Sicherung dahingehend zu schaffen, daß Rundstäbe zur Sicherung des Dämpfungskolbens und des Federstützgliedes verwendet werden. Ein Rundstab läßt sich kraft- und formschlüssig z.B. innerhalb des Federstützgliedes oder auch des Dämpfungskolbens verankern. Auf der gegenüberliegenden Seite befinden sich dann Freibohrungen, in denen diese Rundstäbe bei Betätigung des Türschließers ohne Reibung eintauchen können.In an advantageous embodiment of the object according to the invention, it is possible to provide an inexpensive fuse in such a way that round rods are used to secure the damping piston and the spring support member. A round bar can be positively and positively e.g. anchor within the spring support member or the damping piston. On the opposite side there are free bores in which these round bars can dip without friction when the door closer is actuated.
Die Sicherungsstifte stellen somit eine Verdrehsicherung der Kolben gegenüber der Hubkurvenscheibe dar. Dadurch ist immer gewährleistet, daß der Kolben oder das Federstützglied in ihrer Ursprungslage verbleiben. Werden das Federstützglied oder der Dämpfungskolben aus ihrer Ursprungslage heraus gebracht, so können die Rollen nicht mehr sauber mit der Hubkurvenscheibe zum Eingriff kommen. Es entsteht ein Schieben und Reiben, wodurch ein erhöhter Verschleiß des Türschließers gegeben ist. Auch stimmt der Dämpfungsgrad des Türschließers bei einer Verdrehung des Dämpfungskolbens oder des Federstützgliedes nicht mehr, weil andere Kräfte innerhalb des Türschließers zum Einsatz kommen. Bei einer Verdrehung des Federstützgliedes wird der Kraftverlauf von der Feder über die Rolle auf die Hubkurvenscheibe wesentlich schlechter, und damit sind die geforderten Schließmomente nicht mehr gegeben, was ein sicheres Schließen der Tür unter Umständen nicht gewährleistet.The locking pins thus represent a rotation lock of the pistons with respect to the cam disc. This always ensures that the piston or the spring support member remain in their original position. If the spring support member or the damping piston are brought out of their original position, the rollers can no longer come into engagement with the cam disc properly. There is a pushing and rubbing, which results in increased wear of the door closer. Also, the degree of damping of the door closer is no longer correct when the damping piston or the spring support member is turned, because other forces are used within the door closer. When the spring support member is rotated, the force curve from the spring via the roller to the cam disc is significantly worse, and the required closing torques are no longer provided, which may not ensure that the door is closed securely.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird nachstehend näher erläutert. Es zeigt:
- Figur 1:
- Ein Türschließergehäuse im Ausschnitt mit Dämpfungskolben und Federstützglied und
- Figur 2:
- einen Schnitt durch die Längsachse der Schließerwelle und das Gehäuse
- Figure 1:
- A door closer housing in the cutout with damping piston and spring support and
- Figure 2:
- a section through the longitudinal axis of the closer shaft and the housing
Das in Figur 1 ausschnittsweise dargestellte Gehäuse (1) des Türschließers ist im Schnitt dargestellt worden. Innerhalb des Gehäuses (1) befindet sich die Schließerwelle (2). An der Schließerwelle ist die Hubkurvenscheibe (3) kraft- und formschlüssig verbunden. Mit der Hubkurvenscheibe (3) sind sowohl die Rolle (13) als auch die Kraftübertragungsrolle (14) über Federkräfte, die hinter dem Dämpfungskolben (10) und dem Federstützglied (20) liegen, in Kontakt. Die Rolle (13) befindet sich innerhalb des Dämpfungskolbens (10) und wird durch einen Achsbolzen (11) drehbar im Dämpfungskolben (10) gelagert. Ebenso ist die Kraftübertragungsrolle (14) innerhalb des Federstützgliedes (20) durch einen Achsbolzen (12) drehbar gelagert. Gegen das Federstützglied (20) wird eine Kraft über die Druckfeder (15) über die Kraftübertragungsrolle (14) auf die Hubkurvenscheibe (3) übertragen. Hinter dem Dämpfungskolben (10) befindet sich ebenfalls eine Feder (21). Aufgrund der Federkräfte der Federn (21) und (15) ist es sichergestellt, daß die Rolle (13) und die Kraftübertragungsrolle (14) immer an der Hubscheibenkurve (3) anliegen. Bei Betätigung der Schließerwelle wird die Hubkurvenscheibe (3) verdreht, und der Dämpfungskolben (10) sowie das Federstützglied (20) führen innerhalb des Gehäuses (1) eine gleitende Bewegung aus.The section (1) of the door closer shown in FIG. 1 has been shown in section. The closer shaft (2) is located inside the housing (1). The cam disc (3) is non-positively and positively connected to the closer shaft. Both the roller (13) and the force transmission roller (14) are in contact with the cam disc (3) via spring forces that lie behind the damping piston (10) and the spring support member (20). The roller (13) is located within the damping piston (10) and is rotatably supported in the damping piston (10) by an axle bolt (11). The power transmission roller (14) is also rotatably mounted within the spring support member (20) by means of an axle bolt (12). A force is transmitted against the spring support member (20) via the pressure spring (15) via the force transmission roller (14) to the cam disc (3). A spring (21) is also located behind the damping piston (10). Due to the spring forces of the springs (21) and (15), it is ensured that the roller (13) and the force transmission roller (14) always rest on the cam disc curve (3). When the closer shaft is actuated, the cam disc (3) is rotated and the damping piston (10) and the spring support member (20) execute a sliding movement within the housing (1).
Wie in dem Ausführungsbeispiel dargestellt, befinden sich innerhalb des Federstützgliedes (20) zwei Sicherungsstäbe (8). Diese Sicherungsstäbe verlaufen in Längsachse des Schließergehäuses und quer zur Schließerwelle (2). Sie sind mit dem Federstützglied (20) über eine kraft- und formschlüssige Verbindung (18) fest verbunden. Dieses kann z.B. dadurch geschehen, daß als Sicherungsstäbe (8) Schwerspannstifte vorgesehen werden, die mit einem Preßsitz in dem Federstützglied (20) sitzen. Es wäre genauso gut möglich, diese in den Dämpfungskolben (10) einzudrücken. Entscheidend für die Funktion der Sicherungsstäbe (8) ist es, daß sie dicht an der Schließerwelle (2) ihre Position haben. Sie verlaufen deshalb mit entsprechendem Spiel direkt oberhalb der Hubscheibenkurve (3) und direkt an den beiden Seiten der Längsachse der Schließerwelle (2) vorbei. Oberhalb der Sicherungsstäbe (8) kann sich noch ein Schließerwellenansatz (9) befinden, der die Sicherungsstäbe (8) quasi einbettet. Nach oben hin wird der Schließerwellenansatz (9) benötigt, um das sich im Verschlußstopfen (6) befindliche, jedoch nicht dargestellte Rillenkugellager abzustützen. Im Bereich der Sicherungsstäbe (8) ist dieser Wellenansatz durch eine Nut unterbrochen, um Platz für die Sicherungsstäbe (8) zu schaffen. Durch diese Maßnahme ist es sichergestellt, daß das Federstützglied (20) sich nicht gegenüber der Hubkurvenscheibe (3) verdrehen kann. Weder durch eine Rechts- noch durch eine Linksdrehung würde das Federstützglied (20) seine Position gegenüber der Hubkurvenscheibe (3) verändern.As shown in the exemplary embodiment, two securing rods (8) are located within the spring support member (20). These locking bars run in the longitudinal axis of the closer housing and transverse to the closer shaft (2). They are firmly connected to the spring support member (20) via a non-positive and positive connection (18). This can happen, for example, in that heavy-duty locking pins are provided as securing rods (8), which sit with a press fit in the spring support member (20). It would also be possible to press them into the damping piston (10). It is crucial for the function of the safety rods (8) that they close to the closer shaft (2) To have position. They therefore run with appropriate play directly above the cam disc curve (3) and directly past the two sides of the longitudinal axis of the closer shaft (2). Above the locking bars (8) there can also be a closer shaft extension (9) which virtually embeds the locking bars (8). At the top, the closer shaft extension (9) is required to support the deep groove ball bearing located in the sealing plug (6), but not shown. In the area of the security rods (8), this shaft extension is interrupted by a groove to make room for the security rods (8). This measure ensures that the spring support member (20) cannot rotate with respect to the cam disc (3). The spring support member (20) would not change its position in relation to the cam disc (3) by either a right or a left turn.
Damit auch der gegenüberliegende Dämpfungskolben (10) eine Sicherung gegen Verdrehung erfährt, werden die Sicherungsstäbe (8) entsprechend lang ausgeführt, so daß sie mit einer Spielpassung innerhalb des Dämpfungskolbens (10) in zwei Sackbohrungen (16) reibungslos eintauchen können. Die Sackbohrungen (16) sind in ihrer Tiefe bzw. Länge so bemessen, daß zwischen dem eingeführten Sicherungsstabende (19) und dem Ende der Sackbohrung (16) noch ein genügend großer Freiraum (17) verbleibt. Dieser Freiraum (17) muß so tief bemessen sein, daß bei den Längsbewegungen des Dämpfungskolbens (10) und des Federstützgliedes (20) ein Anschlag der Sicherungsstäbe (8) innerhalb des Dämpfungskolbens nicht (10) stattfindet. Umgekehrt kann auch innerhalb des Federstützgliedes (20) die bereits vorerwähnte Sackbohrung (16) vorhanden sein. Wichtig ist es, daß mindestens zwei Stäbe verwendet werden, denn würde nur ein Stab verwendet, so wären der Dämpfungskolben (10) und das Federstützglied (20) unter Umständen nur gegen eine Drehrichtung gesichert.So that the opposite damping piston (10) is secured against rotation, the locking rods (8) are made long enough so that they can be immersed smoothly with a clearance fit within the damping piston (10) in two blind holes (16). The depth and length of the blind bores (16) are dimensioned such that a sufficiently large free space (17) remains between the inserted safety rod end (19) and the end of the blind bore (16). This free space (17) must be dimensioned so deep that during the longitudinal movements of the damping piston (10) and the spring support member (20) the safety rods (8) do not stop (10) within the damping piston. Conversely, the aforementioned blind bore (16) can also be present within the spring support member (20). It is important that at least two rods are used, because if only one rod were used, the damping piston (10) and the spring support member (20) might only be secured against one direction of rotation.
In dem dargestellten Ausführungsbeispiel sind als Sicherungsstäbe (8) Rundmaterialien verwendet worden. Diese Rundstäbe oder Stifte stellen eine preiswerte Sicherung dar und sind auch bei der Herstellung des Türschließers leicht zu handhaben. Genauso gut können natürlich auch Vierkantmaterialien oder anderes Material verwendet werden.In the illustrated embodiment, round materials have been used as securing rods (8). These round bars or pins represent an inexpensive fuse and are also easy to handle when manufacturing the door closer. Square materials or other materials can of course also be used just as well.
