Description

Aufrollvorrichtung für ein SicherheitsbandRetractor for a security band
Die Erfindung betrifft eine Aufrollvorrichtung für ein Sicherheitsband nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a retractor for a security band according to the preamble of claim 1.
Aus US-A-4,858,551 ist eine Aufrollvorrichtung für ein Sicherheitsband bekannt, welches mit einer reflektierenden Farbe oder einem sonstigen lumineszierenden Material versehen und auf einer Spindel aufgewickelt ist. Die Spindel ist in einem zylinderförmigen als Topf ausgebildeten Gehäuse drehbar gelagert, wobei oben ein drehbarer Deckel mit einem exzentrisch angeordneten Knopf vorgesehen ist. Andererseits ist die Spindel oben mit einem Vierkant versehen, der in einer vierkantigen Aufnahme des Deckels eingelassen ist, so dass die Spindel mit dem Knopf gedreht werden kann. Das Gehäuse weist auf der Aussenseite einen flachen Magneten auf. Ebenfalls weist das Reflektorband an seinem freien Ende einen flachen Magneten auf, so dass das Gehäuse und das aus dem Gehäuse gezogene Reflektorband um der Karosserie eines Autos herum befestigt werden können. Eine Arretierung oder sogar eine Vorspannung des Bandes ist nicht vorgesehen. Ausserdem muss das Band von Hand wieder aufgewickelt werden.From US-A-4,858,551 a retractor for a security tape is known, which is provided with a reflective paint or other luminescent material and is wound on a spindle. The spindle is rotatably supported in a cylindrical housing designed as a pot, with a rotatable cover with an eccentrically arranged button being provided at the top. On the other hand, the spindle is provided with a square at the top, which is embedded in a square receptacle of the cover, so that the spindle can be rotated with the button. The housing has a flat magnet on the outside. The free end of the reflector tape also has a flat magnet, so that the housing and the reflector tape pulled out of the housing can be fastened around the body of a car. A locking or even a pre-tensioning of the band is not provided. In addition, the tape must be rewound by hand.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Aufrollvorrichtung für ein Sicherheitsband vorzusehen, welches selbsttätig wieder aufgewickelt und eine stete Vorspannung auf das Sicherheitsband ausgeübt wird.The present invention is based on the object of providing a retractor for a security band which is automatically rewound and a constant pre-tension is exerted on the security band.
Diese Aufgabe wird durch eine Aufrollvorrichtung mit den Merkmalen des Patent- anspruchs 1 gelöst.This object is achieved by a retractor with the features of claim 1.
Ein grosser Vorteil der erfindungsgemässen Aufrollvorrichtung besteht darin, dass das herausgezogene Band beim Loslassen seines freien Endes automatisch wieder aufgewickelt wird. Ausserdem wird das Band mit zunehmender Länge stärker zurückgezogen wird, was ein sicherer Aufwickelvorgang bewirkt. Ein weiterer Vorteil ist die handliche Form und die kompakte Bauweise der Aufrollvorrichtung. Weitere Vorteile der Erfindung folgen aus den abhängigen Patentansprüchen und aus der nachfolgenden Beschreibung, in welcher die Erfindung anhand eines in den schematischen Zeichnungen dargestellten Ausführungsbeispieles näher er- läutert wird. Es zeigt:A great advantage of the reeling device according to the invention is that the tape that is pulled out is automatically rewound when its free end is released. In addition, the tape is pulled back more with increasing length, which causes a safe winding process. Another advantage is the handy shape and compact design of the retractor. Further advantages of the invention follow from the dependent patent claims and from the following description, in which the invention is explained in more detail with reference to an embodiment shown in the schematic drawings. It shows:

In den Figuren sind für dieselben Elemente jeweils dieselben Bezugszeichen verwendet worden und erstmalige Erklärungen betreffen alle Figuren, wenn nicht ausdrücklich anders erwähnt.In the figures, the same reference numerals have been used for the same elements, and first-time explanations apply to all figures, unless expressly stated otherwise.
In Figur 1 ist eine Aufrollvorrichtung 1 für ein Sicherheitsband (hier nicht gezeichnet) dargestellt, die aus einem kreiszylindrischen Gehäuse 2 mit oben und unten angeordneten Deckel 3 und 4 abgeschlossen werden können. Diese Deckel 3 und 4 können beispielsweise eine umlaufende nach aussen vorstehende Ringwulst aufweisen, die in eine Ringnut auf der Innenwand des Gehäuses 2 eingreifen, so dass sie einen Schnappverschluss bilden. Das Gehäuse 2 ist mittels einer Kreisscheibe 5 mit einem zentralen Loch 6 unterteilt. Im Gehäuse 2 ist eine Spindel 7 mit einem axial vorstehenden kreiszylinderförmigen Nocken 8 versehen, der in einer kreiszylinderförmigen Ausnehmung 9 des unteren Deckels 4 und im zentra- len Loch 6 der Kreisscheibe 5 drehbar gelagert ist. Am anderen Endbereich 12 der Spindel 7 ist eine axial ausgerichetete Aussenverzahnung 13 vorgesehen, die in drei als Zahnräder ausgebildete Planetenräder 14 greifen (vergleiche Figur 2). Diese Zahnräder 14 sind ihrerseits auf der Unterseite mit einem kreisrunden Nocken 16 versehen, die in entsprechende Ausnehmungen 17 drehbar gelagert sind. Die Zahnräder 14 sind ferner in einer Hohlscheibe 18 mit Innenverzahnung 19 drehbar gelagert. Auf der gegenüberliegenden Seite weist die Hohlscheibe 18 eine Achse 21 auf, die in einer kreisrunden Ausnehmung 22 des oberen Deckels 3 drehbar gelagert ist. Auf dieser Achse 21 ist ferner eine flache Spiralfeder 24 befestigt (vergleiche Figur 3), die mit ihrem äusseren Ende an der Innenwand des Gehäuses 2 verbunden ist. Dies kann beispielsweise mit einem L-förmig geboge- nen oder gekröpften Ende erfolgen. Auf der Spindel 7 ist das eine Ende des Sicherheitsband befestigt und das Band darauf aufgewickelt.FIG. 1 shows a retractor 1 for a security band (not shown here), which can be closed off from a circular cylindrical housing 2 with covers 3 and 4 arranged at the top and bottom. These covers 3 and 4 can have, for example, a circumferential outwardly projecting annular bead which engages in an annular groove on the inner wall of the housing 2, so that they form a snap lock. The housing 2 is divided by means of a circular disc 5 with a central hole 6. In the housing 2, a spindle 7 is provided with an axially protruding circular-cylindrical cam 8, which is rotatably mounted in a circular-cylindrical recess 9 of the lower cover 4 and in the central hole 6 of the circular disk 5. At the other end region 12 of the spindle 7, an axially aligned external toothing 13 is provided, which engage in three planet gears 14 designed as gear wheels (see FIG. 2). These gears 14 are in turn provided on the underside with a circular cam 16 which is rotatably mounted in corresponding recesses 17. The gears 14 are also rotatably mounted in a hollow disc 18 with internal teeth 19. On the opposite side, the hollow disc 18 has an axis 21 which is rotatably mounted in a circular recess 22 in the upper cover 3. A flat spiral spring 24 is also fastened on this axis 21 (compare FIG. 3) and is connected at its outer end to the inner wall of the housing 2. This can be done for example with an L-shaped bent or cranked end. On the spindle 7, one end of the security tape is attached and the tape is wound thereon.
In Figur 2 ist ein Querschnitt längs der Linie A-A in Figur 1 durch das Planetengetriebe 26 gezeigt, welches aus der Spindel 7 mit ihrer Aussenverzahnung 13 als Sonnenrad, den Planetenrädern 14 und der Hohlscheibe 18 mit ihrer Innenverzahnung 19 besteht. Ebenfalls ist das als Sicherheitsband dienende Reflektorband 27 angedeutet, das in üblicher Weise aus einem Stoffband mit einer Beschichtung aus reflektierendem Material besteht und auf der Spindel 7 befestigt ist.FIG. 2 shows a cross section along the line A-A in FIG. 1 through the planetary gear 26, which consists of the spindle 7 with its external toothing 13 as a sun gear, the planetary gears 14 and the hollow disk 18 with its internal toothing 19. Also indicated is the reflector tape 27 serving as a security tape, which in the usual way consists of a fabric tape with a coating of reflective material and is attached to the spindle 7.
Wie nun in Figur 3 erkennbar, weist die Spiralfeder 24 einige wenige Windungen auf, weshalb das Planetengetriebe 26 vorgesehen ist. Dadurch wird nämlich eine grössere Übersetzung zwischen der Drehung der Spiralfeder 24 und der Spindel 7 erreicht, wodurch eine wesentlich grössere Länge an Reflektorband auf der Spin- del 7 aufgewickelt werden kann als die Länge der Spiralfeder 24. Das Übersetzungsverhältnis zwischen der maximalen Anzahl Drehungen der Spiralfeder 24 und der Anzahl Drehungen der Spindel 7 ist dabei auf die Länge des Reflektorbandes 27 abgestimmt. Es versteht sich, dass je mehr Band abgewickelt worden ist, je grösser die Zugspannung der Spiralfeder 24 auf das Band 27 wird. Somit kann eine beliebige Länge Reflektorband 27 aus dem Gehäuse 2 gezogen wer- den, was stets gespannt ist. Das herausgezogene Band 27 wird ferner selbsttätig wieder in das Gehäuse 2 hineingezogen, wenn das Bandende losgelassen wird.As can now be seen in FIG. 3, the spiral spring 24 has a few turns, which is why the planetary gear 26 is provided. This means that a greater transmission ratio is achieved between the rotation of the spiral spring 24 and the spindle 7, as a result of which a considerably greater length of reflector tape can be wound on the spindle 7 than the length of the spiral spring 24. The transmission ratio between the maximum number of rotations of the spiral spring 24 and the number of rotations of the spindle 7 is matched to the length of the reflector band 27. It is understood that the more tape has been unwound, the greater the tension of the spiral spring 24 on the tape 27. Any length of reflector tape 27 can thus be pulled out of the housing 2. what is always exciting. The pulled band 27 is also automatically pulled back into the housing 2 when the end of the band is released.
In den Figuren 4 und 5 ist das Gehäuse 2 in perspektivischer Ansicht aus zwei verschiedenen Richtungen dargestellt. Das aus einem Schlitz 28 heraustretende freie Bandende ist mit einem T-förmigen Befestigungsmittel 30 versehen, das ein vollständiges Einziehen des Reflektorbandes 27 in das Gehäuse 2 verhindert. Am Gehäuse 2 ist eine kastenförmige Halterung 31 mit einem Schlitz 32 angebracht, in welche das Befestigungsmittel 30 eingeschoben werden kann (siehe Fig. 4). Somit kann das Band 27 ein Objekt vollständig umfassen, beispielsweise eine Kartonschachtel oder dergleichen, die auf einem Fahrrad zu transportieren ist. Man könnte das Reflektorband 27 auch um den Bauch eines Radfahrers oder eines Wanderers legen, damit er bei Dunkelheit vom entgegenkommenden Autoverkehr besser sichtbar ist. In der Praxis hat das Gehäuse 2 die Grosse von einer Filmkassette für eine Fotokamera und lässt sich damit problemlos mitnehmen.FIGS. 4 and 5 show the housing 2 in a perspective view from two different directions. The free end of the tape emerging from a slot 28 is provided with a T-shaped fastening means 30, which prevents the reflector tape 27 from being completely drawn into the housing 2. A box-shaped holder 31 with a slot 32 is attached to the housing 2, into which the fastening means 30 can be inserted (see FIG. 4). Thus, the belt 27 can completely encompass an object, for example a cardboard box or the like, which is to be transported on a bicycle. You could also put the reflective tape 27 around the belly of a cyclist or a hiker, so that it is more visible in the dark from oncoming car traffic. In practice, the housing 2 is the size of a film cassette for a photo camera and can be easily taken with it.
Es versteht sich für den Fachmann, dass auch andere Arten von Befestigungsmittel verwendet werden können. Beispielsweise könnte man anstelle des T-förmigen Befestigungsmittel 30 ein Klettband vorsehen, wobei das Bandende durch Verdopplung oder Verdreifachung wesentlich dicker gestaltet wird, um zu verhindern, dass das Band 27 vollständig in das Gehäuse 2 hineingezogen wird. Am Gehäuse 2 kann dann ebenfalls ein Streifen Klettband vorgesehen sein, damit eine Klettverbindung zwischen dem Band 27 und dem Gehäuse 2 geformt wird. Die maximale Zugkraft der Spiralfeder 24 muss dabei wesentlich geringer sein als die Kraft, welche benötigt ist, um die Klettverbindung zu lösen. Auch könnte Magnetstreifen als Befestigungsmittel verwendet werden. In einer weiteren Ausgestaltung könnte die Spiralfeder 24 mit einer Rutschkupplung auf der Achse 21 angebracht sein, so dass eine noch grössere Länge Reflektorband 27 aufgewickelt werden kann. In einem solchen Fall wird jedoch nicht alles Reflektorband 27 wieder in das Gehäuse 2 hineingezogen, so dass die Spindel 7 weiter von Hand gedreht muss werden, um alles Band 27 aufzuwickeln. Andererseits kann auch eine dicht gewickelte flache Spiralfeder 24 vorgesehen sein, wie sie in mechanischen Weckern vorsehen sind, wobei der Durchmesser der aufgewundenen Spiralfeder 24 demjenigen der Spindel 7 entsprechen soll. It is understood by those skilled in the art that other types of fasteners can be used. For example, instead of the T-shaped fastening means 30, a Velcro band could be provided, the end of the band being made much thicker by doubling or tripling in order to prevent the band 27 from being pulled completely into the housing 2. A strip of Velcro can then also be provided on the housing 2 so that a Velcro connection is formed between the band 27 and the housing 2. The maximum tensile force of the spiral spring 24 must be significantly less than the force required to release the Velcro connection. Magnetic strips could also be used as fasteners. In a further embodiment, the spiral spring 24 could be attached to the axis 21 with a slip clutch, so that an even greater length of the reflector tape 27 can be wound up. In such a case, however, not all of the reflector tape 27 is pulled back into the housing 2, so that the spindle 7 must be rotated further by hand in order to wind up all of the tape 27. On the other hand, can a tightly wound flat spiral spring 24 can also be provided, as is provided in mechanical alarm clocks, the diameter of the wound spiral spring 24 should correspond to that of the spindle 7.
