Definitions
- the invention relates to a receiving device for the end region of a roller guide rail of a door leaf, in particular one-piece overhead door leaf, in particular in the upper end region of vertically arranged roller guide rails, into which the rollers of the door leaf enter upon transition into the gate opening state, with a damping body made of flexible material, e.g. Rubber or rubber-like deformation and damping behavior is fixed in the end region of the respective running rail at least against an offset movement in the longitudinal direction of the running rail.
- a damping body made of flexible material, e.g. Rubber or rubber-like deformation and damping behavior
- the edge of a door leaf lying at the top in the closed position can also be dampened with a buffer device located far enough in the interior, but here with one-piece door leaves that can be moved overhead, due to the non-linear path behavior between the lower edge and the upper edge of the door leaf, it is relatively early and thus a long-range damping effect is required which, due to the energy storage that occurs only with this damping with spring-elastic elements, emits a reaction force which becomes effective after the door leaf has come to a standstill and which acts on the door leaf in the direction of movement into the closed position.
- a receiving device for the end region of a roller guide rail of a door leaf in which a damping body made of elastic material is arranged in the end region of the rail, against which a chassis provided with rollers can abut in a damping manner.
- the invention is based on the object of providing a receiving device of the type mentioned at the outset, which draws as much kinetic energy as possible from the door leaf which reaches a final position, in particular an open position, in particular a manually operated door leaf, i.e. has the least possible reaction in the sense of the opposite movement of the door leaf.
- this object is achieved in that the damping body of the movable roller of the door leaf guided in the guide rail has a V-shaped ramp surface, the leg surfaces of which are shaped approximately tangentially to the circumference of the running roller.
- the damping body provided and designed according to the invention made of resilient material, which is not necessarily plastically deformable due to the repeated repetition of stress and in this respect has spring-elastic properties, is due to its special shape in Auflauf Design Colour, namely V-shaped opening towards the roller to be picked up, effective in terms of energy drainage of the running roller and thus the door leaf not only through the deformation work, but above all also in that the roller engaging with its peripheral surface on both leg surfaces of the damping body at least one of these surfaces rubs and thus generates losses.
- the V-shaped run-up surface has leg surfaces which are shaped so as to be oriented approximately tangentially to the circumference of the run-up roller. Already because of the change in shape during the run-up, this tangential alignment of the leg surfaces to the circumference of the roller is to be understood as an indication with a large deviation range.
- the damping body is held by means of a screw bolt or the like on the central web (or high web) between the running surface and the counter-holding surface of the running rail, and preferably in such a way that the damping body can be pivoted about the axis of the screw bolt.
- the damping body is provided for easy pivoting about the bolt axis with a bushing which can be pivoted about the bolt, possibly with the interposition of a spacer sleeve which is effective in the longitudinal direction of the bolt.
- the damping body can adapt to the running roller, which - especially in the case of vertically arranged guide rails - runs between the running surface and the counter surface in a necessary play in mutually offset positions.
- the oscillating suspension ensures that the roller comes to rest on both leg surfaces of the V-shaped recess of the damping body.
- the receiving device should catch the roller in a sense, so that a backward movement of the door leaf is avoided. At the same time, however, clamping, which can only be overcome with greater effort in the course of the return movement, should be avoided.
- This "catch effect" is already achieved by the design of the damping body according to the invention, it is further supported in a further preferred embodiment of the invention in that a resilient, flexible threshold projection is arranged in the path of movement of the roller in the running rail in the vicinity of the damping body, which distance between the running surface running approximately perpendicular to the central web of the running rail and the counter-running surface running approximately perpendicular to the central web of the running rail with regard to the diameter of the running roller.
- such a threshold projection is designed as an end shape of a leaf spring element, which engages through the running surface of the running rail or alternatively also through the counter-holding surface in the context of a correspondingly dimensioned opening, possibly slot-shaped.
- the leaf spring element is preferably fixed in the context of a clip connection on the running rail or its end region having the damping element.
- the screw bolt holding the damping body possibly simultaneously used for the fixing of the running rail — is used in a support bracket design for the running rail, which is supported in a fixed position directly or via the frame frame. In this way, the impact-like forces are not directed onto the running rail when the roller starts up against the damping body, but rather directly into the stationary mounting area.
- the above-mentioned holding device is suitable for a wide variety of door leaves.
- it is particularly suitable for relatively light, one-piece door leaves which can be moved overhead, for example for a door in which rollers are provided in the lateral central height region of the door leaf, which run in vertical guide rails which extend approximately upwards from this central height region.
- a handlebar is provided which is articulated in the area of the lower third of the door leaf as seen from the closed position is and at the other end is pivotally mounted in the upper frame area.
- Such a door leaf has a weight compensation device with a torsion spring which extends approximately horizontally above the door opening to be closed and rope drums arranged on a correspondingly running rod serving as a shaft, the rope end to be fastened to the door leaf approximately in the region of the rollers, in particular on their axes, attacks.
- these rollers are arranged approximately in the middle area between half the height and the lower third of the door leaf, when viewed in the closed state.
- FIG. 1 shows a running rail 1 with a running roller 2 located approximately in the end position of the associated opened door leaf, specifically restricted to the upper end region 3 of the running rail.
- a damping body 4 is provided which, facing the roller 2, has a V-collecting surface 5, which is formed by leg regions 6 and 7 of the damping body 4.
- the inclination of the leg surfaces is such that it is oriented approximately tangentially to the peripheral surface 8 of the roller 2 are.
- the damping body 4 is fixed with the aid of a screw bolt 9, which also serves to fasten the running rail, to a bracket, not shown, for the stationary mounting of the running rail, so that forces exerted on the screw bolt 9 are derived directly into on-site areas.
- the damping body 4 is provided with a socket 13, which is intended to symbolize that the damping body 4 is held movably around the shaft of the screw bolt 9 and can thus adapt or align to the running roller in the assembled state, which necessarily between the Tread 11 and the counter surface 12, which are integrally connected by the central web 10, has a certain freedom of movement. This ensures that the roller 2 running against the damping body 4 acts equally on both leg surfaces of the legs 6 and 7 of the damping body. When starting and also releasing the legs spread by the start of the roller 2, friction is inevitably generated between the leg surfaces 5 and the peripheral surface 8 of the roller 2.
- a leaf spring element 14 which has a threshold projection 15 at its free end.
- the leaf spring element is arranged on the outside of the tread 11 of the rail 1, and its threshold projection extends through a slot-shaped opening 17 in the tread 11, so that the threshold projection 15 projects into the path of movement of the roller 2.

Abstract
Description
Die Erfindung bezieht sich auf eine Aufnahmevorrichtung für den Endbereich einer Laufrollen-Führungsschiene eines Torblattes, insbesondere einstückigen über Kopf bewegbaren Torblattes, insbesondere im oberen Endbereich vertikal angeordneter Laufrollen-Führungsschienen, in den die Laufrollen des Torblattes bei Übergang in den Toröffnungszustand einlaufen, wobei ein Dämpfungskörper aus nachgiebigem Werkstoff, z.B. Gummi oder gummiähnlichen Verformungs- und Dämpfungsverhaltens, im Endbereich der jeweiligen Laufschiene zumindest gegen eine Versetzbewegung in Längsrichtung der Laufschiene festgelegt ist.The invention relates to a receiving device for the end region of a roller guide rail of a door leaf, in particular one-piece overhead door leaf, in particular in the upper end region of vertically arranged roller guide rails, into which the rollers of the door leaf enter upon transition into the gate opening state, with a damping body made of flexible material, e.g. Rubber or rubber-like deformation and damping behavior is fixed in the end region of the respective running rail at least against an offset movement in the longitudinal direction of the running rail.
Es ist bekannt, Torblätter mit Hilfe von Gummipuffern oder dergleichen federelastische Anlaufelemente in wenigstens einer ihrer Endstellungen, insbesondere der Öffnungsstellung, dadurch gedämpft aufzunehmen, daß z.B. die in die Öffnungsstellung laufende Unterkante des Torblattes an dem im oberen Horizontalzargenbereich angeordneten Puffer anläuft. Bei Toren mit horizontalen Führungsschienen kann man auch die in Schließstellung oben liegende Kante eines Torblattes mit einer entsprechend weit im Rauminneren gelegenen Puffereinrichtung gedämpft aufnehmen, doch ist hier bei einstückigen über Kopf bewegbaren Torblättern aufgrund des nichtlinearen Wegverhaltens zwischen Unterkante und Oberkante des Torblattes ein verhältnismäßig früh einsetzender und damit langstreckiger Dämpfungseffekt erforderlich, der aufgrund der lediglich erfolgenden Energiespeicherung bei dieser Dämpfung mit federelastischen Elementen eine nach Stillstand des Torblattes wirksam werdende Reaktionskraft abgibt, die das Torblatt in Richtung der Bewegung in die Schließlage beaufschlagt. Bei von Hand betätigten Torblättern führt dies zu einer tatsächlich auftretenden Rückbewegung, die je nach Gewichstausglichsverhalten dazu Führern kann, daß sich das Torblatt bis nahe der halben Schließstellung bewegt, was zu erneutem Angriff von Hand zwingt. Ein solches Rückprallen tritt auch bei dem vorerwähnten Abfangen der Torunterkante durch ein federelastisches Pufferelement im oberen Zargenbereich auf. Solche Pufferelemente sind aufgrund der vielmals wiederholten Beaufschlagung insoweit notwendig federelastisch und nicht bleibend verformbar; der Dämpfungseffekt liegt in erster Linie in der Speicherung von Energie, die dann wieder an das Torblatt zurückgegeben wird, als in einem Energieentzug der praktisch nur durch die Formänderungsarbeit als in Wärme umgesetzter Verlust bedingt ist. Aus der CH-A-657 415 ist ferner eine Aufnahmevorrichtung für den Endbereich einer Laufrollen-Führungsschiene eines Torblattes bekannt, bei welcher ein Dämpfungskörper aus elastischem Werkstoff im Endbereich der Laufschiene angeordnet ist, an welchen ein mit Laufrollen versehenes Fahrgestell dämpfend anschlagen kann.It is known to absorb door leaves with the aid of rubber buffers or similar spring-elastic starting elements in at least one of their end positions, in particular the open position, in such a way that, for example, the lower edge of the door leaf running into the open position runs against the buffer arranged in the upper horizontal frame area. In the case of gates with horizontal guide rails, the edge of a door leaf lying at the top in the closed position can also be dampened with a buffer device located far enough in the interior, but here with one-piece door leaves that can be moved overhead, due to the non-linear path behavior between the lower edge and the upper edge of the door leaf, it is relatively early and thus a long-range damping effect is required which, due to the energy storage that occurs only with this damping with spring-elastic elements, emits a reaction force which becomes effective after the door leaf has come to a standstill and which acts on the door leaf in the direction of movement into the closed position. With manually operated door leaves, this leads to an actually occurring return movement, which depends on the weight compensation behavior this can lead to the fact that the door leaf moves to almost half the closed position, which forces another attack by hand. Such rebounding also occurs when the lower edge of the door is caught by a spring-elastic buffer element in the upper frame area. Such buffer elements are due to the repeated repeated application of spring elastic and not permanently deformable; the damping effect lies primarily in the storage of energy, which is then returned to the door leaf, as in an energy withdrawal which is practically only due to the deformation work as a loss converted into heat. From CH-A-657 415 a receiving device for the end region of a roller guide rail of a door leaf is also known, in which a damping body made of elastic material is arranged in the end region of the rail, against which a chassis provided with rollers can abut in a damping manner.
Der Erfindung liegt die Aufgabe zugrunde, eine Aufnahmevorrichtung der eingangs genannten Art zur Verfügung zu stellen, die dem in eine Endstellung, insbesondere Offenstellung, gelangenden, insbesondere handbetätigten, Torblatt möglichst viel Bewegungsenergie entzieht, d.h. eine möglichst geringe Rückwirkung im Sinne der entgegengesetzten Bewegung des Torblattes auf dieses ausübt.The invention is based on the object of providing a receiving device of the type mentioned at the outset, which draws as much kinetic energy as possible from the door leaf which reaches a final position, in particular an open position, in particular a manually operated door leaf, i.e. has the least possible reaction in the sense of the opposite movement of the door leaf.
Ausgehend von einer Aufnahmevorrichtung mit den eingangs genannten Merkmalen wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß der Dämpfungskörper der in der Laufschiene geführt bewegbaren Laufrolle des Torblattes entgegengerichtet eine V-förmige Auflauffläche aufweist, deren Schenkelflächen etwa tangential zum Umfang der anlaufenden Laufrolle ausgerichtet ausgeformt sind.Starting from a receiving device with the features mentioned above, this object is achieved in that the damping body of the movable roller of the door leaf guided in the guide rail has a V-shaped ramp surface, the leg surfaces of which are shaped approximately tangentially to the circumference of the running roller.
Der erfindungsgemäß vorgesehene und ausgebildete Dämpfungskörper aus nachgiebigem Werkstoff, der aufgrund der vielfach wiederholten Beanspruchung notwendigerweise nicht plastisch verformbar ist und insoweit federelastische Eigenschaften aufweist, ist durch seine besondere Formgebung in Auflaufflächenbereich, nämlich V-förmig sich der aufzunehmenden Laufrolle gegenüber öffnend, hinsichtlich des Energieentzuges der auflaufenden Laufrolle und damit des Torblattes nicht nur durch die Formänderungsarbeit wirksam, sondern vor allem auch dadurch, daß die mit ihrer Umfangsfläche an beiden Schenkelflächen des Dämpfungskörpers angreifende Laufrolle an wenigstens einer dieser Flächen reibt und damit Verluste erzeugt. Diese Reibungsverluste treten auch dann - und vor allem auch unter der Voraussetzung, daß die auflaufende Rolle sich nicht dreht - in jedem Falle auf, wenn man berücksichtigt, daß sich die die V-förmige Auflauffläche zur Verfügung stellenden Schenkelbereiche des Dämpfungskörpers bei Anlauf der Laufrolle spreizen und im Zuge der Rückfederung die Rolle insoweit wieder freigeben.The damping body provided and designed according to the invention made of resilient material, which is not necessarily plastically deformable due to the repeated repetition of stress and in this respect has spring-elastic properties, is due to its special shape in Auflaufflächebereich, namely V-shaped opening towards the roller to be picked up, effective in terms of energy drainage of the running roller and thus the door leaf not only through the deformation work, but above all also in that the roller engaging with its peripheral surface on both leg surfaces of the damping body at least one of these surfaces rubs and thus generates losses. These frictional losses also occur - and above all also under the condition that the running roller does not rotate - in any case if one takes into account that the leg regions of the damping body which provide the V-shaped running surface spread when the running roller starts up and release the role again in the course of the springback.
Die V-förmige Auflauffläche weist Schenkelflächen auf, die etwa tangential zum Umfang der auflaufenden Laufrolle ausgerichtet ausgeformt sind. Schon wegen der Formänderung im Zuge des Auflaufens ist diese tangentiale Ausrichtung der Schenkelflächen zum Umfang der Laufrolle als Angabe mit großem Abweichungsbereich zu verstehen.The V-shaped run-up surface has leg surfaces which are shaped so as to be oriented approximately tangentially to the circumference of the run-up roller. Already because of the change in shape during the run-up, this tangential alignment of the leg surfaces to the circumference of the roller is to be understood as an indication with a large deviation range.
Vorzugsweise ist der Dämpfungskörper mittels eines Schraubbolzens oder dergleichen an dem Mittelsteg (oder Hochsteg) zwischen der Lauffläche und der Gegenhaltefläche der Laufschiene gehalten, und zwar vorzugsweise derart, daß der Dämpfungskörper um die Achse des Schraubbolzens schwenkbar ist. In besonders bevorzugter Ausführung ist der Dämpfungskörper für eine leichte Verschwenkbarkeit um die Schraubbolzenachse mit einer Buchse versehen, die um den Schraubbolzenschafft gelagert verschwenkbar ist, ggfs. unter Zwischenschaltung einer in Längsrichtung des Bolzens wirksamen Abstandhülse. Aufgrund dieser pendelnd beweglichen Halterung des Dämpfungskörpers kann sich dieser an die anlaufende Laufrolle anpassen, die - insbesondere bei vertikal angeordneten Führungsschienen -zwischen der Lauffläche und der Gegenhaltefläche im Rahmen eines notwendigen Spieles in zueinander versetzten Stellungen aufläuft. Durch die pendelnde Aufhängung wird sichergestellt, daß die Laufrolle an beiden Schenkelflächen der V-förmigen Ausnehmung des Dämpfungskörpers zugleich zur Anlage gelangt.Preferably, the damping body is held by means of a screw bolt or the like on the central web (or high web) between the running surface and the counter-holding surface of the running rail, and preferably in such a way that the damping body can be pivoted about the axis of the screw bolt. In a particularly preferred embodiment, the damping body is provided for easy pivoting about the bolt axis with a bushing which can be pivoted about the bolt, possibly with the interposition of a spacer sleeve which is effective in the longitudinal direction of the bolt. Because of this oscillatingly movable mounting of the damping body, the damping body can adapt to the running roller, which - especially in the case of vertically arranged guide rails - runs between the running surface and the counter surface in a necessary play in mutually offset positions. The oscillating suspension ensures that the roller comes to rest on both leg surfaces of the V-shaped recess of the damping body.
Die Aufnahmevorrichtung soll die Laufrolle in gewissem Sinne fangen, so daß eine Rückbewegung des Torblattes vermieden wird. Zugleich aber soll eine Klemmung, die nur unter größerem Kraftaufwand im Zuge der Rückbewegung überwunden werden kann, vermieden werden. Dieser "Fangeffekt" wird bereits durch die erfindungsgemäße Gestaltung des Dämpfungskörpers erreicht, sie wird in weiterhin bevorzugter Ausführung der Erfindung noch dadurch unterstützt, daß in der Bewegungsbahn der Laufrolle in der Laufschiene im Nahbereich vor dem Dämpfungskörper ein federelastisch nachgiebiger Schwellenvorsprung angeordnet ist, der den Abstand zwischen der etwa senkrecht zum Mittelsteg der Laufschiene verlaufenden Lauffläche und der etwa senkrecht zum Mittelsteg der Laufschiene verlaufenden Gegenhaltefläche im Hinblick auf den Durchmesser der Laufrolle verengt. Insbesondere ist ein solcher Schwellenvorsprung als Endausformung eines Blattfederelementes ausgebildet, der die Lauffläche der Laufschiene oder alternativ auch die Gegenhaltefläche im Rahmen einer entsprechend bemessenen Öffnung, ggfs. schlitzförmig, durchgreift. Dabei ist das Blattfederelement vorzugsweise im Rahmen einer Klippverbindung an der Laufschiene bzw. deren das Dämpfungselement aufweisenden Endbereich festgelegt.The receiving device should catch the roller in a sense, so that a backward movement of the door leaf is avoided. At the same time, however, clamping, which can only be overcome with greater effort in the course of the return movement, should be avoided. This "catch effect" is already achieved by the design of the damping body according to the invention, it is further supported in a further preferred embodiment of the invention in that a resilient, flexible threshold projection is arranged in the path of movement of the roller in the running rail in the vicinity of the damping body, which distance between the running surface running approximately perpendicular to the central web of the running rail and the counter-running surface running approximately perpendicular to the central web of the running rail with regard to the diameter of the running roller. In particular, such a threshold projection is designed as an end shape of a leaf spring element, which engages through the running surface of the running rail or alternatively also through the counter-holding surface in the context of a correspondingly dimensioned opening, possibly slot-shaped. The leaf spring element is preferably fixed in the context of a clip connection on the running rail or its end region having the damping element.
Weiterhin bevorzugt wird der den Dämpfungskörper haltende Schraubbolzen - ggfs. gleichzeitig für die Festlegung der Laufschiene ausgenutzt - in eine Haltebockausbildung für die Laufschiene eingesetzt, die unmittelbar bzw. über den Zargenrahmen ortsfest abgestützt ist. Auf diese Weise werden die stoßartigen Kräfte beim Anlauf der Rolle gegen den Dämpfungskörper nicht auf die Laufschiene, sondern unmittelbar in den ortsfesten Halterungsbereich geleitet.Furthermore, the screw bolt holding the damping body — possibly simultaneously used for the fixing of the running rail — is used in a support bracket design for the running rail, which is supported in a fixed position directly or via the frame frame. In this way, the impact-like forces are not directed onto the running rail when the roller starts up against the damping body, but rather directly into the stationary mounting area.
Grundsätzlich ist die vorgeschilderte Aufnahmevorrichtung für Torblätter unterschiedlichster Bauart geeignet. Als bevorzugtes Verwendungsbeispiel eignet sie sich vor allem für verhältnismäßig leichte einstückige über Kopf bewegbare Torblätter, beispielsweise für ein Tor, bei dem im seitlichen Höhenmittelbereich des Torblattes Rollen vorgesehen sind, die in vertikalen, sich etwa von diesem Höhenmittelbereich nach oben hin erstreckenden Führungsschienen laufen. darüber hinaus ist ein Lenker vorgesehen, der im Bereich etwa des unteren Drittes des torblattes von der Schließlage aus gesehen angelenkt ist und anderen Endes im oberen Zargenbereich verschwenkbar gelagert ist. Ein solches Torblatt weist eine Gewichtsausgleichseinrichtung mit oberhalb der zu verschließenden Toröffnung sich etwa horizontal erstreckenden Torsionsfeder und an einer entsprechend verlaufenden, als Welle dienenden Stange verdrehfest angeordnete Seiltrommeln auf, wobei das am Torblatt zu befestigende Seilende etwa im Bereich der Rollen, insbesondere an deren Achsen, angreift. Diese Rollen sind bei einer praktischen Ausführung etwa im Mittelbereich zwischen der Hälfte der Höhe und dem unteren Drittel des Torblattes - im Schließzustand betrachtet - angeordnet.Basically, the above-mentioned holding device is suitable for a wide variety of door leaves. As a preferred example of use, it is particularly suitable for relatively light, one-piece door leaves which can be moved overhead, for example for a door in which rollers are provided in the lateral central height region of the door leaf, which run in vertical guide rails which extend approximately upwards from this central height region. In addition, a handlebar is provided which is articulated in the area of the lower third of the door leaf as seen from the closed position is and at the other end is pivotally mounted in the upper frame area. Such a door leaf has a weight compensation device with a torsion spring which extends approximately horizontally above the door opening to be closed and rope drums arranged on a correspondingly running rod serving as a shaft, the rope end to be fastened to the door leaf approximately in the region of the rollers, in particular on their axes, attacks. In a practical version, these rollers are arranged approximately in the middle area between half the height and the lower third of the door leaf, when viewed in the closed state.
Diese und weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen, insbesondere unter Bezugnahme auf das in der Zeichnung wiedergegebene Ausführungsbeispiel, dessen nachfolgende Beschreibung die Erfindung näher erläutert.These and further refinements of the invention result from the subclaims, in particular with reference to the exemplary embodiment shown in the drawing, the following description of which explains the invention in more detail.

Figur 1 zeigt eine Laufschiene 1 mit in dieser etwa in der Endstellung des zugeordneten geöffneten Torblattes befindlichen Laufrolle 2, und zwar beschränkt auf den oberen Endbereich 3 der Laufschiene. Im oberen Randabschnitt des Endbereiches 3 ist ein Dämpfungskörper 4 vorgesehen, der der Laufrolle 2 zugewandt eine V-Auffangfläche 5 aufweist, die durch Schenkelbereiche 6 und 7 des Dämpfungskörpers 4 gebildet ist. Wie insbesondere auch Figur 2 erkennen läßt, ist die Neigung der Schenkelflächen derart getroffen, daß sie etwa tangential zu der Umfangsfläche 8 der Laufrolle 2 ausgerichtet sind. Der Dämpfungskörper 4 ist mit Hilfe eines Schraubbolzens 9, der zugleich der Befestigung der Laufschiene dient, an einem nicht dargestellten Haltebock zur ortsfesten Halterung der Laufschiene festgelegt, so daß auf den Schraubbolzen 9 ausgeübte Kräfte unmittelbar in bauseitige Bereiche abgeleitet werden. Der Dämpfungskörper 4 ist mit einer Buchse 13 versehen, die versinnbildlichen soll, daß der Dämpfungskörper 4 um den Schafft des Schraubbolzens 9 herum beweglich gehalten ist und sich somit im montierten Zustand an die auflaufende Laufrolle anpassen bzw. auf diese ausrichten kann, die notwendigerweise zwischen der Lauffläche 11 und der Gegenhaltefläche 12, die durch den Mittelsteg 10 einstückig verbunden sind, eine gewisse Bewegungsfreiheit hat. Dadurch wird sichergestellt, daß die gegen den Dämpfungskörper 4 anlaufende Laufrolle 2 in jedem Falle beide Schenkelflächen der Schenkel 6 und 7 des Dämpfungskörpers gleichermaßen beaufschlagt. Beim Anlaufen und auch beim Freigeben der durch den Anlauf der Laufrolle 2 gespreizten Schenkel wird zwangsläufig eine Reibung zwischen den Schenkelflächen 5 und der Umfangsfläche 8 der Laufrolle 2 erzeugt.FIG. 1 shows a running rail 1 with a running
Um einen "Fangeffekt" zu erzielen, d.h. ein Zurückprallen der Laufrolle und damit ein Zurückbewegen des Torblattes in Richtung auf die Schließstellung zusätzlich zu vermeiden, ist ein Blattfederelement 14 vorgesehen, das an seinem freien Ende einen Schwellenvorsprung 15 aufweist. Das Blattfederelement ist außenseitig der Lauffläche 11 der Schiene 1 angeordnet, und sein Schwellenvorsprung durchgreift eine schlitzförmige Öffnung 17 in der Lauffläche 11, so daß der Schwellenvorsprung 15 in die Bewegungsbahn der Laufrolle 2 hineinragt. An seinem entgegengesetzten Ende ist das Blattfederelement mittels einer Klippverbindung 16 im Stirnkantenbereich der Laufschiene 1 festgelegt. Mit diesem Schwellenvorsprung wird zusätzlich zur dämpfenden Wirkung des Körpers 4 ein Hindernis gegen eine Rückwärtsbewegung der anlaufenden Rolle 2 zur Verfügung gestellt, das keine Klemmung, sondern nur einen unter geringer Kraft zu überwindenden Rückrollwiderstand darstellt.In order to additionally achieve a "catch effect", ie to prevent the roller from rebounding and thus moving the door leaf back towards the closed position, a

Claims (8)
- Receiving device for the end portion (3) of a roller guide rail (1) of a door, particularly a one-piece up-and-over door, particularly in the upper end portion (3) of vertically mounted roller guide rails (1) into which the rollers (2) of the door run during the transition into the open position of the door, a shock absorbing member (4) of resilient material, e.g. rubber or a material having rubber-like deformation and shock-absorption characteristics, being secured in the end portion (3) of the rail (1) in question in such a way as to prevent displacement of said member (4) at least in the longitudinal direction of the rail (1),
characterised in that the shock absorbing member (4) has a V-shaped approach surface (5) directed counter to the roller (2) of the door panel movably guided in the rail (1), the arms of the 'V' (6, 7) being formed so as to lie substantially at a tangent to the circumference (8) of the oncoming roller (2). - Receiving device according to claim 1,
characterised in that the shock absorbing member (4) is held by means of a threaded bolt (9) or the like on the central bar (10) between the running surface (11) and the counter-surface (12) of the rail (1). - Receiving device according to claim 2,
characterised in that the shock absorbing member (4) is held so as to be oscillatably movable about the longitudinal axis of the threaded bolt (9) extending perpendicularly to the surface of the central bar (10). - Receiving device according to claim 3,
characterised in that the shock absorbing member (4) is provided with a bushing (13) which is less resilient than the material of the shock absorbing member (4), the threaded bolt (9) extending through this bushing (13) with some play, optionally with an interposed spacer sleeve acting in the longitudinal direction of the threaded bolt. - Receiving device according to one of claims 1 to 4,
characterised in that, in the path of travel of the roller (2) in the rail (1), in the area just in front of the shock absorbing member (4), there is a springily resilient threshold projection (15) which narrows the gap between the running surface (11) extending substantially perpendicularly to the central bar (10) of the rail (1) and the counter-surface (12) extending substantially perpendicularly to the central bar (10) of the rail (1), in terms of the diameter of the roller (2). - Receiving device according to claim 5,
characterised in that the threshold projection (15) is constructed as the terminal formation of a leaf spring element (14) which passes through the running surface (11) of the rail (1) within an opening of suitable dimensions, the leaf spring element (14) being attached to the rail (1). - Receiving device according to claim 6,
characterised in that the end of the leaf spring element (14) remote from the terminal formation (15) is fixed to the terminal edge portion of the rail (1) in the manner of a clip connection (16). - Receiving device according to one of claims 2 to 7,
characterised in that the threaded bolt (9) passing through the shock absorbing member (4) in order to secure the latter simultaneously serves to secure the rail (1) and extends right into the supporting structure of the rail (1), which is preferably fixed to the door frame.
