Abstract

The proposed winch (8) has a drive roller (11) and a guide roller (10) and a second guide element, preferably a second roller (12). A rope which is led between the guide rollers (10, 12) forms a loop (25) around the drive roller (11). The drive roller (11) can slide towards the guide roller (10). When a rope end (2, 13) is pulled, the rope is forced by the first guide roller (12) against the drive roller (11) to produce a strong working connection by friction which is preferably further enhanced by a peripheral V-shaped groove (22). The flanks of the groove (22) will advantageously have in addition an uneven surface, further improving the coupling between the drive roller (11) and rope (25). An appropriate arrangement of the guide rollers (10, 12) can ensure optimal wrap around the drive roller (11). A preferred use of the winch (8) is with rope hoisting and lowering devices, in particular when lifting heavy loads or persons.

Description

Die vorliegende Erfindung bezieht sich auf eine Handwinde gemäss Oberbegriff des Anspruchs 1.The present invention relates to a hand winch according to the preamble of claim 1.

Eine mit einer Handkurbel versehbare Winde ist beispielsweise aus der DE-OS-1 481 900 bekannt. Diese vor allem zum Abseilen vorgesehene Winde weist eine drehbare Rolle mit einer Nut auf, in welcher mehrere Windungen eines Seilvorrates angeordnet sind. Ein hydraulischer Energiewandler bremst die Drehgeschwindigkeit der Rolle beim Abseilen. Mittels einer Handkurbel kann ein geeignetes Übersetzungsglied angetrieben werden, um sich mit dem Abseilgerät auch hinaufwinden zu können.A winch with a hand crank is known for example from DE-OS-1 481 900. This before all winch intended for abseiling has a rotatable Roll with a groove in which several turns of one Rope stocks are arranged. A hydraulic one Energy converter slows down the rotation speed of the roller Abseiling. Using a hand crank, a suitable one Translation link are driven to deal with the Abseil device also to be able to wind up.

Aus der US-PS 4,058,294 auf der sich der Oberbegriff des Anspruchs 1 basiert, geht eine drehbar gelagerte, mit einer Nut versehene Treibrolle sowie eine gleichgrosse Führungsrolle einer Winde hervor. Am Umfang von beiden Rollen liegt ein Seil an. Durch eine Zugbelastung des Seiles kann die Treibrolle auf die Führungsrolle zubewegt werden.From US-PS 4,058,294 on which the preamble of claim 1 is based, a rotatably mounted is included a grooved drive roller and an equal size Leading role of a winch. The extent of both There is a rope on rollers. By pulling the rope the drive roller can be moved towards the guide roller.

In der EP 0 110 250 A2 ist eine Antriebseinrichtung für ein Zugseil gezeigt, bei dem zwei Umlenkrollen an einem Wiegebalken angeordnet sind, der bezüglich einer Antriebsrolle um zwei in einem Lagerrahmen befestigten Zapfen schwenkbar und lediglich zu Zwecken einer Voreinstellung auch verschiebbar ausgebildet ist. Im Betrieb können sich die Zugkräfte auf das Seil sowie die dadurch bedingten Reibungskräfte zwischen dem Zugseil und den Umlenkrollen und der ebenfalls am Lagerrahmen angeordneten Antriebsrolle dadurch einstellen, dass einmal der Lagerrahmen um die ortsfeste Achse der Antriebsrolle und zum anderen der Wiegebalken innerhalb des Lagerrahmens um die Achse seiner Zapfen pendelt. EP 0 110 250 A2 describes a drive device for a Traction rope shown, with two pulleys on one Weighing beams are arranged with respect to a Drive roller fastened by two in a bearing frame Pin pivotable and only for purposes of one Presetting is also slidable. Operational the tensile forces on the rope as well as the result conditioned friction forces between the pull rope and the Deflection rollers and the one also arranged on the bearing frame Adjust the drive roller by moving the Bearing frame around the fixed axis of the drive roller and to other of the weighing beams within the storage frame around the The axis of its spigot swings.

Auf-/Abseilgeräte, z.B. gemäss der europäischen Patentveröffentlichung EP-A-0 480 117 der Anmelderin, werden bevorzugt dafür eingesetzt, Personen oder Lasten an einem Seil heraufzuziehen bzw. herunterzulassen. Bevorzugte Einsatzgebiete sind das Rettungswesen oder allgemein der mobile Einsatz dieser Geräte. Die Auf-/Abseilgeräte haben im Wesentlichen die Funktion einer Reduktion der Rückhaltekraft beim Abseilen in Verbindung mit einer Sicherung gegen unkontrolliertes Abstürzen der am Seil hängenden Person oder Last.Ascending / descending devices, e.g. according to the European Applicant's patent publication EP-A-0 480 117 preferably used to carry people or loads on one Pulling up or lowering the rope. preferred Areas of application are rescue services or in general mobile use of these devices. The up / down ropes have in Essentially the function of reducing the restraining force when abseiling in connection with a protection against uncontrolled falling of the person hanging on the rope or Load.

Es hat sich nun gezeigt, dass das Ziehen mit der Hand oder auch mit einem speziellen Handgriff bei unvorhergesehen schweren Lasten oder über grössere Zughöhen die ziehende Person überfordern kann. Dadurch kann es zu einem unbeabsichtigten Wiederabseilen kommen, wenn auch durch die Sicherungseinrichtung des Auf-/Abseilgerätes abgebremst wird. Weitere mögliche Folgen sind Blessuren (Abschürfungen, Blasen) und Ermüdungserscheinungen bei der ziehenden Person.It has now been shown that pulling by hand or even with a special handle for unforeseen heavy loads or over greater heights Person can overwhelm. This can lead to a unintentional rappelling come, albeit through the Safety device of the ascending / descender device braked becomes. Other possible consequences are injuries (abrasions, Blisters) and signs of fatigue in the pulling person.

Ist das Auf-/Abseilgerät an der Spitze eines Dreibocks angebracht, so besteht auch die Gefahr des Überziehens und des Umkippens des Dreibocks.Is the up / down rope device at the top of a tripod attached, there is also a risk of overdrawing and of tipping the tripod.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung anzugeben, die das Ziehen an einem Zugseil erleichtert und sich einfach auf der Zugseite eines Auf/Abseilgerätes mit dem Zugseil in Eingriff bringen lässt.The object of the present invention is therefore a Specify device that pulling on a pull rope relieved and easy on the pull side of an up / down rope device can engage with the pull rope.

Eine derartige Vorrichtung ist in Form einer Winde im Anspruch 1 angegeben. Die weiteren Ansprüche nennen bevorzugte Ausführungsformen der erfindungsgemässen Winde. Such a device is in the form of a winch in the Claim 1 specified. Name the other claims preferred embodiments of the winch according to the invention.

Die erfindungsgemässe Winde zeichnet sich demnach dadurch aus, dass das Zugseil über eine erste Führungsrolle um eine mit einer umlaufenden Nut versehene Treibrolle herum und schliesslich über eine zweite Führungsrolle geführt wird. Die Treibrolle ist dabei verschiebbar gelagert, so dass sie unter dem Zug des Seiles gegen die Führungsrollen gedrückt wird. Insbesondere die Lauffläche der ersten Führungsrolle drückt dabei das Seil in den Einschnitt der Treibrolle hinein, wodurch zumindest ein Reibschluss des Seiles mit der Treibrolle entsteht. Eine Drehbewegung der Treibrolle führt danach zu einer entsprechenden Bewegung am Zugseil. In der einfachsten Form verfügt die Treibrolle über eine Handkurbel, ein motorischer Antrieb zum Beispiel durch einen Getriebemotor ist jedoch ebenfalls denkbar.The winch according to the invention is accordingly characterized from that the pull rope over a first guide role by one with a circumferential groove provided driving roller around and is ultimately led by a second leadership role. The drive roller is slidably mounted so that it pressed against the guide rollers while pulling the rope becomes. In particular the tread of the first guide roller presses the rope into the cut of the drive roller into it, whereby at least a frictional connection of the rope with the driving roller arises. A rotating movement of the drive roller then leads to a corresponding movement on the pull rope. In its simplest form, the drive roller has one Hand crank, a motor drive for example however, a geared motor is also conceivable.

Die umlaufende Nut in der Treibrolle ist bevorzugt konisch zulaufend, d. h. mit im wesentlichen V-förmigem Querschnitt, ausgeführt und zusätzlich mit einer unebenen Oberfläche ausgestattet, um einerseits ein sicheres Einklemmen des Seils zu bewirken und durch die Formgebung der Oberfläche zusätzlich eine Formschlusskomponente zwischen Seil und Treibrolle zu erhalten.The circumferential groove in the drive roller is preferably conical tapering, d. H. with a substantially V-shaped Cross section, executed and additionally with an uneven Surface equipped to ensure a safe hand Pinch the rope and cause by the shape the surface also has a positive locking component between rope and traction roller.

Die Führungsrollen sind so bevorzugt angeordnet, dass sich eine Umschlingung der Treibrolle von mindestens 180° und bevorzugt deutlich mehr ergibt.The guide rollers are preferably arranged so that a looping of the drive roller of at least 180 ° and preferably gives significantly more.

Die Erfindung soll im weiteren anhand eines Ausführungsbeispieles unter Bezugnahme auf Figuren weiter beschrieben werden.

Wie Figuren 1 und 2 zeigen, durchläuft das Seil 2, das vom Auf-/Abseilgerät kommt und unter entsprechendem Zug steht, zunächst einen vorbekannten Handgriff 3, der mit einer Klemmvorrichtung 4 versehen ist. Die Klemmvorrichtung 4 sperrt ein Zurücklaufen des Seiles 2. Derartige Handgriffe dienen zum Beispiel dazu, von Hand ein Seil gegen die Klemmrichtung der Klemmvorrichtung zu ziehen. Der Handgriff weist Bohrungen 5 auf, mit denen er auf Bolzen 6 aufgesetzt werden kann. Die Bolzen 6 befinden sich fest auf der Grundplatte 7 der Handwinde 8. Das Seil 2 verläuft vom Handgriff 3 aus unter einer Führungsplatte 9 hindurch, über eine zweite Führungsrolle 10, um die Treibrolle 11 herum und schliesslich über die erste, ausgangsseitige Führungsrolle 12, von wo das freie Ende 13 des Seiles frei herunterhängt.As Figures 1 and 2 show, the rope 2 passes through the Up / down rope device comes and is under appropriate tension, first a known handle 3, which with a Clamping device 4 is provided. The clamping device 4 prevents the rope 2 from running back serve, for example, to pull a rope against the hand Pull the clamping direction of the clamping device. The handle has holes 5 with which it is placed on bolt 6 can be. The bolts 6 are firmly on the Base plate 7 of the hand winch 8. The rope 2 runs from Handle 3 from under a guide plate 9, over a second guide roller 10 around the drive roller 11 and finally via the first, output side Guide roller 12 from where the free end 13 of the rope is free hangs.

Die Führungsrollen 10 und 12 können einfache, auf Achsen 14 frei drehbar gelagerte Rollen mit ebener Lauffläche sein. Bevorzugt ist jedoch die zweite Führungsrolle 10 mit einer konkaven Lauffläche ausgestattet, wie sie Figur 4 zeigt. Um die Führung des Seiles 2 zur ersten Führungsrolle 12 weiter zu verbessern, ist noch eine Führungszunge 15 vorhanden.The guide rollers 10 and 12 can be simple, on axes 14th freely rotating castors with a flat tread. However, the second guide roller 10 with one is preferred concave tread, as shown in Figure 4. Around the guidance of the rope 2 to the first guide roller 12 To improve, there is still a guide tongue 15.

Die Führungsrollen 10, 12 sind möglichst nah nebeneinander angeordnet, damit sich einerseits eine möglichst weitgehende Umschlingung der Treibrolle 11 durch den schlaufenförmigen Seilabschnitt 25 ergibt, ohne dass die gegenläufig zwischen den Führungsrollen 10, 12 durchlaufenden Seilabschnitte 2, 13 einander behindern. Die Umschlingung ist der Winkelbereich, in dem der Seilabschnitt 25 fest an der Treibrolle 11 anliegt, wenn diese an die Führungsrollen 10, 12 angedrückt ist.The guide rollers 10, 12 are as close as possible to one another arranged so that one hand as possible extensive wrapping of the drive roller 11 by the loop-shaped rope section 25 results without the in opposite directions between the guide rollers 10, 12 continuous rope sections 2, 13 hinder each other. The Wrapping is the angular range in which the Rope section 25 bears firmly against the drive roller 11 when this is pressed against the guide rollers 10, 12.

Die Treibrolle 11 ist leicht drehbar auf einem Achsstummel 18 gelagert, der sich auf dem Gleiter 19 befindet. Der Gleiter 19 ist verschiebbar im Einschnitt 20 in der Grundplatte 7 angeordnet. Als Sicherung gegen Herausrutschen des Gleiters 19 aus dem Einschnitt ist noch eine Sicherung 21 vorhanden, im vorliegenden Fall eine Schraube mit einer Unterlagescheibe, die die Oeffnung des Einschnitts 20 verengt. An der Treibrolle 11 ist direkt die Kurbel 16 mit drehbar gelagertem Handgriff 17 angebracht.The drive roller 11 is easily rotatable on an axle stub 18 stored, which is located on the slider 19. The Slider 19 is slidable in the incision 20 in the Base plate 7 arranged. As a safeguard against Slipping out of the slider 19 from the incision is still a fuse 21 is present, in the present case Screw with a washer that covers the opening of the Incision 20 narrowed. On the drive roller 11 is the Crank 16 with rotatably mounted handle 17 attached.

Wie bereits in Figur 1 zu sehen, liegt der schlaufenförmige Seilabschnitt 25 vollständig in der Nut 22 der Treibrolle 11 (Figur 3). Die Flanken 23 der Nut 22 sind, wie im Schnitt durch die Treibrolle 11 in Figur 2 zu sehen, zusätzlich mit Vertiefungen 24 ausgestattet, die auf den beiden Flanken 23 gegeneinander versetzt angeordnet sind. Die damit erzeugte Unebenheit der Flankenoberfläche erzeugt einen zusätzlichen Formschluss zwischen dem Seilabschnitt 25, der in der Nut 22 liegt, und der Treibrolle 11.As can already be seen in Figure 1, the loop-shaped Rope section 25 completely in the groove 22 of the drive roller 11 (Figure 3). The flanks 23 of the groove 22 are, as in Section through the drive roller 11 can be seen in FIG. 2, additionally equipped with recesses 24 which on the two flanks 23 are arranged offset from one another. The unevenness of the flank surface created with this creates an additional form fit between the rope section 25, which lies in the groove 22, and the drive roller 11th

In Figur 2 ist, im Gegensatz zu Figur 1, der Zustand der Treibrolle 11 während der Betätigung der Handwinde 8 dargestellt: Unter dem Zug des Seils 2 hat sich die Treibrolle 11 auf die Führungsrollen 10, 12 zubewegt, wobei deren Laufflächen, insbesondere diejenige der ersten Führungsrolle 12, das Seil 2, 25 tief in die Nut 22 hineindrücken. Hierdurch wird eine Kopplung des Seils 2, 25 mit der Treibrolle 11 bewirkt, die bei zunehmendem Zug am Seil 2 noch stärker wird. Anfänglich kann, wenn der Zug noch von der Klemmvorrichtung 4 aufgenommen wird, auch durch Ziehen am freien Ende 13 das Andrücken der Treibrolle 11 an die Führungsrollen 10, 12 bewirkt werden. U. a. für die Verwendbarkeit für verschiedene Seildicken ist die Nut 22 im Querschnitt V-förmig ausgebildet.In FIG. 2, in contrast to FIG. 1, the state of the Driving roller 11 during the operation of the hand winch 8 shown: Under the pull of the rope 2, the Drive roller 11 moved to the guide rollers 10, 12, wherein their treads, especially that of the first Guide roller 12, the rope 2, 25 deep in the groove 22nd Push. As a result, the rope 2, 25 is coupled with the drive roller 11, which with increasing train on Rope 2 becomes even stronger. Initially, when the train is still picked up by the clamping device 4, too by pulling the free end 13 to press the drive roller 11 to the guide rollers 10, 12 are effected. Among other things For the usability for different rope thicknesses is the groove 22 V-shaped in cross section.

Umgekehrt ist auch ein Lösen des Seiles 2, 25 möglich, solange die Klemmvorrichtung 4 des Handgriffs 3 wirksam ist: Wird die Treibrolle 11 in Gegenrichtung zum Pfeil 26 bewegt, so übernimmt die Klemmvorrichtung 4 den Zug am Seil 2, und unter weiterem Drehen der Treibrolle 11 kann diese von den Führungsrollen 10, 12 wegbewegt werden und das Seil 25 aus der Treibrolle 11 entnommen werden. Vorteilhaft wirkt die Klemmvorrichtung 4 hier auch in dem Falle, dass der Handgriff 17 versehentlich losgelassen wird ("Totmannsicherung").Conversely, loosening the rope 2, 25 is also possible, as long as the clamping device 4 of the handle 3 is effective is: If the drive roller 11 is in the opposite direction to the arrow 26 moves, the clamping device 4 takes over the pull on the rope 2, and with further rotation of the drive roller 11, this can be moved away from the guide rollers 10, 12 and the rope 25 are removed from the drive roller 11. Advantageous the clamping device 4 also acts here in the event that the handle 17 is accidentally released ( "Totmannsicherung").

Figur 3 zeigt schliesslich noch die bevorzugte Befestigungsvorrichtung 30, die an der Rückseite der Grundplatte 7 angebracht ist. Sie besteht im wesentlichen aus einer Klemmvorrichtung mit einer Klemmschraube 31. Damit kann die Handwinde zum Beispiel an einem Profilrohr 32 eines Dreibeins befestigt werden, an dessen Spitze das Auf-/Abseilgeät befestigt ist, zum Beispiel bei Aufstellung über einer Schachtöffnung.Figure 3 finally shows the preferred Fastening device 30, which is at the back of the Base plate 7 is attached. It essentially exists from a clamping device with a clamping screw 31. This allows the hand winch to be attached to a profile tube, for example 32 of a tripod are attached, at the top of which Rope / descender is attached, for example when installing over a shaft opening.

Aus der vorstehenden Beschreibung eines bevorzugten Ausführungsbeispieles sind dem Fachmann zahlreiche Varianten zugänglich, ohne den Bereich der Erfindung zu verlassen. Denkbar ist unter anderem, statt oder zusätzlich zum Handkurbelantrieb einen motorischen Antrieb, zum Beispiel durch einen elektrischen Getriebemotor, vorzusehen. Die Handwinde kann auch ohne Halterung für den Handgriff 3 ausgeführt werden, sofern auf diese Sicherungsfunktion verzichtet werden kann. Statt der offenen Ausführung, die das Einlegen eines beliebigen Seilabschnitts 25 als Schlaufe in die Handwinde erlaubt, könnten auch geschlossene Führungen vorgesehen sein, durch die das Seil hindurchgeführt wird, um eine bessere Seilführung zu bewirken. Die Laufflächen der Führungsrollen können insbesondere plan oder konkav, aber auch auf eine andere Art ausgeführt sein. Denkbar ist auch eine Rücklaufsicherung in den Lagern der Führungsrollen bzw. der Treibrolle.From the above description of a preferred Exemplary embodiments are numerous to the person skilled in the art Variants accessible without the scope of the invention leave. It is conceivable, among other things, instead of or in addition for the hand crank drive a motor drive, for Example by an electric gear motor, provided. The hand winch can also be used without a holder for the Handle 3 are executed, if applicable Security function can be dispensed with. Instead of the open design, the insertion of any Rope section 25 allowed as a loop in the hand winch, closed guides could also be provided through which the rope is passed through for better To effect rope guidance. The running surfaces of the guide rollers can in particular be flat or concave, but also on a another type. One is also conceivable Backflow protection in the bearings of the guide rollers or Capstan roller.

Denkbar ist es auch, die Treibrolle 11 durch eine Schwenkbewegung an die Führungsrollen anzudrücken. Dabei könnte auch auf die zweite Führungsrolle 10 verzichtet werden und stattdessen eine einfache, stationäre oder sich mit der Treibrolle mitbewegende Seilführung vorgesehen werden.It is also conceivable that the drive roller 11 by a Press the swivel movement onto the guide rollers. there could also dispense with the second guide roller 10 and instead be a simple, stationary or yourself provided with the traction roller moving cable guide become.

Die Handkurbel kann in der Länge verstellbar sein. Die Öffnung des Einschnitts 20 kann vollständig durch eine aufgeschraubte oder anderweitig befestigte Platte o. ä. vollständig verschlossen sein.The hand crank can be adjustable in length. The Opening of the incision 20 can be made completely by a screwed or otherwise secured plate or similar be completely closed.

Da Auf-/Abseilgeräte und in der Folge auch die Winde oft transportabel sein müssen, d.h. geringes Gewicht aufweisen sollten, sind die bevorzugten Materialien für die Teile der Handwinde hochwertige Aluminiumlegierungen und zum Beispiel für die geringer belasteten Führungsrollen Kunststoff. Die Materialwahl kann jedoch unter den jeweils geltenden Anforderungen in weitem Rahmen frei getroffen werden, so lange unter den Einsatzbedingungen eine sichere Kopplung des Zugseiles an die Treibrolle gewährleistet ist. In diesem Zusammenhang kann es auch möglich sein, auf eine unebene, insbesondere kantige Formgebung der Oberflächen der Flanken 23 zu verzichten, wenn sich eine ausreichende Haftreibung zwischen dem Zugseil und den Oberflächen der Flanken 23 auch ohne diese Vorkehrungen ergibt.Because up / down ropes and consequently also the winch often must be transportable, i.e. light weight should be the preferred materials for the parts of the Hand winch high quality aluminum alloys and for example for the lower loaded plastic guide rollers. The However, material selection can be made under the applicable ones Requirements are freely met in a wide range, so a safe coupling for a long time under the operating conditions the traction cable to the drive roller is guaranteed. In In this context, it may also be possible to uneven, especially angular shape of the surfaces to waive the flanks 23 if there is sufficient Stiction between the pull rope and the surfaces of the Flanks 23 results without these precautions.
