Abstract
Description
Die Erfindung betrifft eine Manschette zum Schutz vor Brüchen von Federn, insbesondere von Drehfedern.The The invention relates to a cuff for protection against fractures of Springs, in particular torsion springs.
Im Bereich von handbetätigten Toranlagen, die in vertikaler Richtung zu öffnen sind, werden diese zur einfachen Handhabung in den meisten Fällen mit einem System Drehfeder-Seil/Seilrollen mit mechanischer Anpassung der Stellungskonstellation angeboten.in the Range of hand-operated Gate systems, which are to be opened in the vertical direction, these are the easy handling in most cases with a system torsion spring rope / pulleys with mechanical adjustment of the position constellation offered.
Es werden Drehfedern zur Energiespeicherung eingesetzt, um mit einer möglichst geringen Handkraft den Torflügel öffnen und schließen zu können. Hierzu werden in horizontaler Richtung oberhalb des Torflügels Drehfedern positioniert, die in ihrem Zentrum über eine Welle geführt werden. An den Enden werden die Drehfedern einerseits an der Seilrolle und an dem anderen Ende an einem Spannverschluss gelagert.It Torsion springs are used for energy storage, with a preferably small hand force open the gate and shut down to be able to. For this purpose, in the horizontal direction above the gate torsion springs positioned over a shaft at their center. At the ends of the torsion springs on the one hand to the pulley and stored at the other end to a snap lock.
Bei den üblichen Ausführungen derartiger mit Hand zu betätigenden Toranlagen werden diese nach dem Stand der Technik frei zugänglich und sichtbar – wie oben beschrieben – im Gebäudeinneren platziert.at the usual versions such hand-operated Gate systems, these are freely accessible and visible according to the prior art - as above described - im indoor placed.
Die Zeit- und Dauerfestigkeit dieser Drehfedern ist begrenzt. Riss- und Scheuerstellen bei der Montage und der Einfluss von Korrosion mindern deren Lebensdauer. Somit kann es irgendwann zu einem nicht genau bekannten Zeitpunkt zum Bruch dieser Drehfedern kommen. Dabei können sich Teile der Federwicklungen, des Federdrahtes, auf Grund der in der Feder vorhandenen potentiellen Energie durch den Raum geschleudert werden. Derartige Federn stellen daher eine erhebliche Gefahr für das Leben und die Gesundheit der sich im Gebäude aufhaltende Personen dar, die sich in der Nähe dieser Toranlagen befinden.The Time and fatigue strength of these torsion springs is limited. Crack- and chafing during assembly and the influence of corrosion reduce their service life. Thus, someday it can not well-known time to break these torsion springs come. there can Parts of the spring windings, the spring wire, due to the in the spring of potential energy thrown around the room become. Therefore, such springs pose a significant danger to life and life the health of the building people staying in the vicinity of these gates.
Nach dem Stand der Technik sind aufwendige Einhausungen als Schutzeinrichtung von Drehfedern bekannt, die kostenaufwendig herzustellen sind und örtlich an die jeweilige Situation angepasst werden müssen. Um Sichtkontrollen durchführen zu können, müssen diese Einhausungen jedoch zur Prüfung der Drehfeder de- und später wieder remontiert werden.To the prior art are expensive housings as a protective device known from torsion springs, which are costly and locally the respective situation must be adapted. To perform visual inspections can, have to these enclosures, however, for consideration the torsion spring and later be remounted again.
Des weiteren ist allgemein bekannt, Schutzschläuche oder Manschetten über Zugfedern anzuordnen. Die Montage derartiger Schutzschläuche oder Manschetten setzt jedoch voraus, dass die Feder zunächst im nicht montierten Zustand vorliegen muss beziehungsweise ein solcher Zustand durch Demontage herzustellen ist. Dies bedeutet einen erheblichen Aufwand für die Überprüfung der Feder und deren Nachrüstung mit dem Schutzschlauch beziehungsweise der Manschette. Zudem sind diese Schläuche und Manschetten kaum in der Lage, Federbruchstücke festzuhalten und deren Bruchenergie zu absorbieren.Of another is well known, protective hoses or sleeves via tension springs to arrange. The installation of such protective tubes or sleeves sets however, assume that the spring is initially unassembled must exist or such a state by disassembly is to produce. This means a considerable effort for the review of Spring and its retrofitting with the protective tube or the cuff. In addition are these tubes and cuffs barely able to hold spring fragments and their Absorb breakage energy.
Aufgabe der Erfindung ist es daher, eine verbesserte Manschette zum Schutz vor Brüchen von Federn, insbesondere von Drehfedern, bereitzustellen, deren Montage ohne De- und Remontage der Feder leicht handhabbar ist und mit der Vorkehrungen getroffen sind, Verletzungen von Personen im Falle eines Federbruches zu vermeiden.task The invention therefore provides an improved cuff for protection before breaks of springs, in particular of torsion springs to provide, whose Assembly without disassembly and reassembly of the spring is easy to handle and with the precautions taken, injuries of persons in the case to avoid a spring break.
Erfindungsgemäß wir die Aufgabe durch eine Manschette mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Manschette ergeben sich aus den Merkmalen der Ansprüche 2 bis 7.According to the invention we Task by a cuff with the features of claim 1 solved. Advantageous embodiments of the invention cuff arise from the features of the claims 2 to 7.
Die erfindungsgemäße Manschette, die sich ohne De- und Remontage der Feder aufbringen und entfernen lässt, ist mechanisch in der Lage, bei Bruch der Feder die mit den herausgebrochenen und herausgeschleuderten Bruchstücken verbundene Energie zu absorbieren. Bruchstücke der Feder werden aufgefangen und verbleiben in der Manschette, die insofern wie ein Schutzmantel wirkt.The cuff according to the invention, which apply and remove without disassembly and reassembly of the spring leaves, is mechanically capable of breaking the spring with the broken out and ejected fragments to absorb connected energy. Fragments of the spring are caught and remain in the cuff, insofar as a protective sheath acts.
Die erfindungsgemäße Manschette lässt Formänderungen einer Feder in einem begrenzten Umfang zu und behindert nicht die betriebsmäßige Wirkung der Feder. Sie besitzt eine Verschleißfestigkeit, die in der Regel wesentlich größer ist als die Lebensdauer einer Feder.The Cuff according to the invention leaves shape changes a spring to a limited extent and does not hinder the operational effect the feather. It has a resistance to wear, which usually is much larger as the life of a spring.
