Definitions
- the invention relates to a roller door with side guide rails and a, in particular high-speed, door leaf, in which between the end area of the door leaf and the end edge region facing away from the end edge of the door leaf, the door opening to be closed with the door leaf or the like, at least one over a remaining path of the door leaf whose transition to the opening position exciting spring is arranged which engages a tension formation which is provided on the end area, in particular a end profile of the door leaf.
- a roller door in a known design is mentioned here with guide rails or guide profiles, in which the side edges of the door leaf are displaceably guided between the closed position and the open position.
- Such door leaves are generally rolled up and down on rollers, but they can also be moved to a different position when changing to the open position.
- door leaves made of profiles which follow one another in the direction of movement come into consideration, for example made of aluminum, or else so-called hangings made of continuous, correspondingly flexible films and the like.
- high speeds are aimed for, which leads to corresponding accelerations or decelerations in the final phases of the respective movement.
- the invention has for its object to provide a roller door of the type mentioned, in which the door leaf can be moved with high accelerations and decelerations, without the closing area of the door leaf moving irregularly relative to the other door leaf area.
- the spring is formed as a torsion spring from a torsion section and an actuating section designed as a lever arm and is pretensioned with the latter at a stop in the closed position of the door leaf.
- the spring intercepts the end area of the door leaf when it is moved into the open position over the last travel area, the spring being tensioned.
- the force in the direction of this movement acts on the end area of the door leaf and additionally accelerates it into the closed position.
- the end area of the door leaf can neither shift in the deceleration to the end of the opening process nor in the acceleration at the start of the closing process relative to the remaining area of the door leaf in such a way that the dangers described above of sliding away over the Roll or wrinkle occur.
- the spring can in principle be fixed in the end region of the door leaf and cooperate with a tension formation which is provided in the upper end region of the edge of the door opening, for example a frame part or the upper end region of the associated guide rail.
- each of the springs is preferably fixed in the edge region of the door opening to be closed and works together with a tension formation, which is provided in the end region of the door leaf, as shown in the exemplary embodiment described below.
- the spring acts as a force accumulator that can be charged in one direction and releases its energy in the opposite direction.
- mechanical springs designed as torsion springs are used.
- roller door is not limited to door openings in buildings, it can also be openings of vehicles or the like.
- an upper corner region of a door opening 1 is shown, which is delimited at the top by a horizontal lintel 2 and whose side edges are defined by two guide rails, only one of which is shown 3.
- the guide rail can be a hollow guide profile.
- the door opening 1 shown only in the upper corner area is to be closed or released by a door leaf 4 shown in a correspondingly limited manner, which can be wound up and unwound in a known manner and not shown on a carrier roller.
- This carrier roller is also provided in a manner not shown with a motor drive.
- the door leaf 4 is shown in a position shortly before the opening end position is reached, so that its end region 5, which is designed as an end profile, has already lifted far from the bottom-side closed position.
- the end edge of the end profile facing away from the lintel 2 can be formed by the downward-facing limitation of a safety strip 6.
- a spring designated 8 in each case is fastened to the guide rails 3, by means of a base plate 9 fastened in the upper region of the respective guide rail, on which a holding body 10 is provided for the spring.
- the spring 8 has one Torsion section 11, which consists of a plurality of turns surrounding the holding body and is secured against rotation with one end on the holding body.
- the torsion section 11 continues in an actuating section 12, which is also made of spring steel and interacts with a tensioning formation 13 which is arranged on the end profile.
- This tension formation can be designed as a cylindrical projection, as can be seen in the drawing.
- a stop 14 is provided on the base plate 9, against which the spring comes to rest when it disengages from the associated tensioning formation 13.
- the attack on the stop 14 of the spring 8 is made with a greater or lesser prestress, which depends on the course of the force introduced when the tensioning formation 13 is attacked on the actuating section 12 of the spring 8 in the end region 5 of the door leaf.
- Other influencing variables on this force curve are, of course, the strength of the spring itself, the lever arm under which the actuating section 12 acts on the tensioning formation 13 and the like.
Abstract
Description
Die Erfindung betrifft ein Rolltor mit seitlichen Führungsschienen und einem, insbesondere schnellaufend angetriebenen, Torblatt, bei welchen zwischen dem Abschlußbereich des Torblattes und dem von der Abschlußkante des Torblattes abgewandten Endrandbereich der mit dem Torblatt abzuschließenden Toröffnung oder dergleichen wenigstens eine sich über einen Restweg des Torblattes bei dessen Übergang in die Öffnungslage spannende Feder angeordnet ist, die an einer Spannausbildung angreift, die an dem Abschlußbereich, insbesondere einem Abschlußprofil des Torblattes vorgesehen ist.The invention relates to a roller door with side guide rails and a, in particular high-speed, door leaf, in which between the end area of the door leaf and the end edge region facing away from the end edge of the door leaf, the door opening to be closed with the door leaf or the like, at least one over a remaining path of the door leaf whose transition to the opening position exciting spring is arranged which engages a tension formation which is provided on the end area, in particular a end profile of the door leaf.
Hier angesprochen ist ein Rolltor in grundsätzlich bekannter Ausgestaltung mit Führungsschienen bzw. Führungsprofilen, in welchen die Seitenränder des Torblattes zwischen der Schließlage und der Öffnungslage verschiebbar geführt sind. Solche Torblätter werden in der Regel auf Walzen auf- und abgerollt, sie können aber auch beim Übergang in die Öffnungsstellung in eine andere Position verfahren werden.A roller door in a known design is mentioned here with guide rails or guide profiles, in which the side edges of the door leaf are displaceably guided between the closed position and the open position. Such door leaves are generally rolled up and down on rollers, but they can also be moved to a different position when changing to the open position.
Man ist bestrebt, solche Torblätter leichtgewichtig auszugestalten, um die für den Bewegungsvorgang erforderliche Kraft klein zu halten. Hier kommen Torblätter aus in Bewegungsrichtung aufeinanderfolgenden Profilen in Betracht, beispielsweise aus Aluminium, oder aber auch sogenannte Behänge aus durchgehenden, entsprechend flexiblen Folien und dergleichen mehr. Insbesondere im Falle motorischen Antriebes strebt man hohe Geschwindigkeiten an, was zu entsprechenden Beschleunigungen bzw. Verzögerungen in den Endphasen der jeweiligen Bewegung führt.Efforts are being made to make such door leaves lightweight in order to keep the force required for the movement process small. Here, door leaves made of profiles which follow one another in the direction of movement come into consideration, for example made of aluminum, or else so-called hangings made of continuous, correspondingly flexible films and the like. In the case of motor drives in particular, high speeds are aimed for, which leads to corresponding accelerations or decelerations in the final phases of the respective movement.
Betrachtet man das Überführen des Torblattes in den Öffnungszustand, so besteht die Gefahr, daß bei entsprechend hoher Verzögerung zu Ende der Torblattbewegung dessen Abschlußbereich, also beispielsweise ein Abschlußprofil oder ein entsprechend kleiner Restlappenbereich eines Behanges, aufgrund der darin noch vorhandenen Bewegungsenergie über die Rolle hinweg rutscht. Beim Schließen unter entsprechender Beschleunigung zu Beginn des Bewegungsvorganges kann die Trägheit des Abschlußbereiches des Torblattes dazu führen, daß sich an der der zu verschließenden Toröffnung abgewandten Seite eine Schlaufe bildet. Eine schwere Ausbildung des Abschlußbereiches des Torblattes, beispielsweise durch Einlage eines Flacheisens oder dergleichen, kann dieses Verhalten nur bedingt beeinflussen und steht der beabsichtigten leichten Ausbildung des Torblattes insgesamt entgegen.If one considers the transfer of the door leaf into the open state, there is a risk that, with a correspondingly high delay at the end of the door leaf movement, its end region, for example a end profile or a correspondingly small remaining flap region of a curtain, will slide over the roller due to the kinetic energy still present therein . When closing under appropriate acceleration at the beginning of the movement process can the inertia of the closing area of the door leaf cause a loop to form on the side facing away from the door opening to be closed. A heavy design of the end area of the door leaf, for example by inserting a flat iron or the like, can only influence this behavior to a limited extent and is contrary to the intended light design of the door leaf as a whole.
Es ist bereits bekannt - DE-A-2015916 -, einen Rolladen mittels im Bereich seiner Fußlatte angeordneter federnder oder elastisch dämpfender Körper bei Übergang in den Öffungszustand am Rolladenkasten schlag- und geräuschgedämpft abzufangen und durch gespeicherte Federkraft klapperfrei zu halten. Die in diesem Zusammenhang angesprochenen Federkörper sind im Schließzustand bzw. fehlendem Anschlag des Rolladens an dem Rolladenkasten nicht vorgespannt und müssen zur Verhinderung eines zu großen Endöffnungsweges gegen die Kraft der Federkörper entsprechend "hart" ausgebildet sein.It is already known - DE-A-2015916 - to intercept a roller shutter by means of resilient or elastically damping bodies arranged in the region of its footrest upon transition into the open state on the roller shutter box and to keep them rattle-free by stored spring force. The spring bodies mentioned in this context are not pretensioned in the closed state or in the absence of the roller shutter against the roller shutter box and must be designed to be correspondingly “hard” in order to prevent a too large end opening path against the force of the spring bodies.
Ein weiterhin bekanntgewordener Rollvorhang - FR-A-2279315 - arbeitet mit einem Federelement, das unter elastischer Kraft in seiner Lage gehalten ist und als Anschlag am oberen Ende der seitlichen Führungsschienen dient.Another roll curtain that has become known - FR-A-2279315 - works with a spring element, which is held in place under elastic force and serves as a stop at the upper end of the side guide rails.
Der Erfindung liegt die Aufgabe zugrunde, ein Rolltor der eingangs genannten Art zur Verfügung zu stellen, bei dem das Torblatt mit hohen Beschleunigungen und Verzögerungen bewegt werden kann, ohne daß sich der Abschlußbereich des Torblattes gegenüber dem anderen Torblattbereich unregelmäßig bewegt.The invention has for its object to provide a roller door of the type mentioned, in which the door leaf can be moved with high accelerations and decelerations, without the closing area of the door leaf moving irregularly relative to the other door leaf area.
Ausgehend von einem Rolltor mit den eingangs genannten Merkmalen wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Feder als Torsionsfeder aus einem Torsionsabschnitt und einem als Hebelarm ausgebildeten Betätigungsabschnitt ausgebildet und vorgespannt mit letzterem in der Schließstellung des Torblattes an einem Anschlag abgestützt ist.Starting from a roller door with the features mentioned above, this object is achieved according to the invention in that the spring is formed as a torsion spring from a torsion section and an actuating section designed as a lever arm and is pretensioned with the latter at a stop in the closed position of the door leaf.
Durch die Feder wird zum einen der Abschlußbereich des Torblattes bei dessen Überführung in die Öffnungsstellung über den letzten Wegbereich hinweg abgefangen, wobei die Feder gespannt wird. Bei Überführen des Torblattes aus der Öffnungsstellung in die Schließstellung wirkt die Kraft in Richtung dieser Bewegung auf den Abschlußbereich des Torblatt ein und beschleunigt diesen zusätzlich in die Schließstellung. Damit kann sich der Abschlußbereich des Torblattes weder bei der Verzögerung zu Ende des Öffnungsvorganges noch bei der Beschleunigung zu Beginn des Schließvorganges gegenüber dem übrigen Bereich des Torblattes derart verschieben, daß die eingangs geschilderten Gefahren eines Hinweggleitens über die Rolle oder einer Faltenbildung auftreten.On the one hand, the spring intercepts the end area of the door leaf when it is moved into the open position over the last travel area, the spring being tensioned. When the door leaf is transferred from the open position to the closed position, the force in the direction of this movement acts on the end area of the door leaf and additionally accelerates it into the closed position. Thus, the end area of the door leaf can neither shift in the deceleration to the end of the opening process nor in the acceleration at the start of the closing process relative to the remaining area of the door leaf in such a way that the dangers described above of sliding away over the Roll or wrinkle occur.
Es ist grundsätzlich möglich, nur eine Feder zwischen dem Abschlußbereich des Torblattes und dem oberen Bereich der Toröffnungsberandung vorzusehen. In bevorzugter Ausführung wird jedoch in je einem Seitenrandbereich des Torblattes eine Feder vorgesehen.In principle, it is possible to provide only one spring between the end area of the door leaf and the upper area of the edge of the door opening. In a preferred embodiment, however, a spring is provided in each side edge area of the door leaf.
Die Feder kann grundsätzlich im Abschlußbereich des Torblattes festgelegt sein und mit einer Spannausbildung zusammenwirken, die im oberen Endbereich der Toröffnungsberandung, beispielsweise eines Zargenteiles oder aber dem oberen Endbereich der zugehörigen Führungsschiene vorgesehen ist. Je nach Ausbildung und im Sinne einer Gewichtsersparnis für das Torblatt wird jede der Federn vorzugsweise im Randbereich der zu verschließenden Toröffnung festgelegt und arbeitet mit einer Spannausbildung zusammen, die im Abschlußbereich des Torblattes vorgesehen ist, wie dies das nachstehend geschilderte Ausführungsbeispiel wiedergibt.The spring can in principle be fixed in the end region of the door leaf and cooperate with a tension formation which is provided in the upper end region of the edge of the door opening, for example a frame part or the upper end region of the associated guide rail. Depending on the design and in the sense of a weight saving for the door leaf, each of the springs is preferably fixed in the edge region of the door opening to be closed and works together with a tension formation, which is provided in the end region of the door leaf, as shown in the exemplary embodiment described below.
Die Feder wirkt als Kraftspeicher, der in eine Richtung aufladbar ist und seine Energie in der Gegenrichtung wieder abgibt. Dazu werden hier mechanische Federn in Ausbildung als Torsionsfeder verwendet.The spring acts as a force accumulator that can be charged in one direction and releases its energy in the opposite direction. For this purpose, mechanical springs designed as torsion springs are used.
Der Einsatz des Rolltores ist nicht auf Toröffnungen in Gebäuden beschränkt, hier kann es sich auch um Öffnungen von Fahrzeugen oder dergleichen handeln.The use of the roller door is not limited to door openings in buildings, it can also be openings of vehicles or the like.
Bevorzugte Ausführungen ergeben sich aus den Ünteransprüchen im Zusammenhang mit dem in der Zeichnung wiedergegebenen Ausführungsbeispiel.Preferred embodiments result from the subclaims in connection with the embodiment shown in the drawing.
In der Zeichnung ist ein oberer Eckbereich einer Toröffnung 1 wiedergegeben, die nach oben hin durch einen horizontalen Sturz 2 begrenzt ist und deren Seitenränder durch zwei Führungsschienen definiert sind, von denen nur eine 3 dargestellt ist. Bei der Führungsschiene kann es sich um ein hohles Führungsprofil handeln.In the drawing, an upper corner region of a
Die nur im oberen Eckbereich wiedergegebene Toröffnung 1 ist durch ein entsprechend beschränkt wiedergegebenes Torblatt 4 zu verschließen bzw. freizugeben, das in bekannter Weise und nicht dargestellt auf eine Trägerwalze auf- und abwickelbar ist. Diese Trägerwalze ist in ebenfalls nicht dargestellter Weise mit einem motorischen Antrieb versehen.The
Das Torblatt 4 ist in einer Stellung kurz vor Erreichen der Öffnungsendlage gezeigt, so daß sich sein als Abschlußprofil ausgebildeter Endbereich 5 bereits weit aus der bodenseitigen Schließstellung abgehoben hat. Die dem Sturz 2 abgewandte Abschlußkante des Abschlußprofiles kann durch die nach unten weisende Begrenzung einer Sicherheitsleiste 6 gebildet sein.The door leaf 4 is shown in a position shortly before the opening end position is reached, so that its
Im oberen Endbereich 7 der Toröffnung 1 ist jeweils an den Führungsschienen 3 je eine insgesamt mit 8 bezeichnete Feder befestigt, und zwar mittels einer im oberen Bereich der jeweiligen Führungsschiene befestigten Grundplatte 9, an der ein Haltekörper 10 für die Feder vorgesehen ist. Die Feder 8 weist einen Torsionsabschnitt 11 auf, der aus mehreren, den Haltekörper umgebenden Windungen besteht und mit einem Ende an dem Haltekörper verdrehsicher festgelegt ist. Am anderen Ende setzt sich der Torsionsabschnitt 11 in einem Betätigungsabschnitt 12 fort, der ebenfalls aus Federstahl besteht und mit einer Spannausbildung 13 zusammenwirkt, die an dem Abschlußprofil angeordnet ist. Diese Spannausbildung kann als zylinderförmiger Vorsprung ausgebildet sein, wie dies die Zeichnung erkennen läßt. Im Übergangsbereich zwischen dem Torsionsabschnitt 11 und dem Betätigungsabschnitt 12 der Feder 8 ist an der Grundplatte 9 ein Anschlag 14 vorgesehen, an den die Feder zur Anlage kommt, wenn sie außer Eingriff mit der zugehörigen Spannausbildung 13 gerät. Der Angriff an dem Anschlag 14 der Feder 8 ist unter mehr oder weniger großer Vorspannung getroffen, was davon abhängt, welchen Verlauf der bei Angriff der Spannausbildung 13 an dem Betätigungsabschnitt 12 der Feder 8 in den Endbereich 5 des Torblattes eingeleiteten Kraft man wünscht. Weitere Einflußgrößen auf diesen Kraftverlauf sind natürlich die Stärke der Feder selbst, der Hebelarm, unter dem der Betätigungsabschnitt 12 an der Spannausbildung 13 angreift und dergleichen mehr.In the upper end region 7 of the gate opening 1, a spring designated 8 in each case is fastened to the
Es ist klar ersichtlich, daß ein Angriff der Spannausbildung 13 an dem Betätigungsabschnitt 12 der Feder 8 erst erfolgt, wenn nur noch eine im Verhältnis zum Gesamtweg geringe Strecke in die Öffnungsendstellung hinein zurückzulegen ist, d.h. sich der Abschlußbereich 5 des Torblattes 1 bereits nahe seiner Endstellung an dem Sturz befindet. Auf diese Weise wird nun verhindert, daß der Speichervorgang der Federkraft über einen größeren Abschnitt der Bewegungsstrecke hinweg ausgedehnt ist, was den Antrieb belasten würde, zum anderen wirkt die im Zuge des Schließvorganges in den Abschlußbereich 5 eingeleitete Kraft nur solange unmittelbar auf das Torblatt 1 ein, bis der vom Sturz 2 her in die Toröffnung 1 hineinreichende Abschnitt des Torblattes 1 aufgrund seines Gewichtes selbst der von der angetriebenen Trägerwalze freigegebenen Schließbewegung folgt.It is clearly evident that the
