Abstract

The invention relates to a cable winding device in which a cable drum (2) is rotatably mounted on a stationary flange wall and, in order to wind up a cable (4), can be driven by spring force in the winding-up direction, this device further having a braking element (6) acting on a braking surface connected to the cable drum (2) which element, when the cable drum (2) is rotated in the winding-up direction, automatically passes into a position blocking this rotation, from which it can be released by means of an unlocking element (10). Complete freedom from frictional forces of the braking element acting during the drawing-off of the cable (2) is achieved in that a release element (12) is provided which is adjustable by the traction exerted during the drawing-off of the cable (2), and the braking element (6) can be completely lifted off the braking surface by the adjustment motion of this release element. <IMAGE>

Description

Die Erfindung betrifft eine Kabelaufwickelvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a cable winder according to the preamble of claim 1.

Eine solche Vorrichtung ist durch die DE-0S 33 16 977 bekannt. Als Bremselement ist bei dieser Vorrichtung auf dem Außenumfang eines an der Kabeltrommel angeformten Ringansatzes eine Schlingfeder angeordnet. Der Innendurchmesser der Schlingfeder ist geringfügig kleiner bemessen als der Außendurchmesser des Ringansatzes, so daß die Schlingfeder im Ruhezustand am Außen­umfang des Ringansatzes anliegt. Das eine Ende der Schlingfeder ist verdrehfest an der feststehenden Flanschwand der Kabel­trommel befestigt. Das andere Ende der Schlingfeder ist da­gegen mit einem Entriegelungselement gekoppelt, das von Hand betätigt werden kann. Beim Betätigen des Entriegelungselementes wird das andere Ende der Schlingfeder im Sinne einer Aufweitung der Schlingfeder verstellt, so daß die Blockierung der Kabel­trommel in Aufwickelrichtung aufgehoben wird und die Kabel­trommel damit durch einen Federmotor in Aufwickelvorrichtung gedreht werden kann. Beim Abziehen des Kabels wird die Schling­feder durch die entsprechende Drehung der Kabeltrommel infolge der zwischen der Schlingfeder und dem Außenumfang des Ringan­satzes bestehenden Reibung in Richtung ihrer Aufweitung ver­dreht und dadurch zumindest soweit gelockert, daß eine Drehung der Kabeltrommel in Abziehrichtung möglich ist. Dabei bleibt aber die Schlingfeder in Anlage an der Umfangsfläche des Ring­ansatzes, so daß eine entsprechende Reibungskraft beim Abziehen des Kabels überwunden werden muß.Such a device is known from DE-0S 33 16 977. In this device, a wrap spring is arranged as a braking element on the outer circumference of a ring attachment molded onto the cable drum. The inner diameter of the wrap spring is dimensioned slightly smaller than the outer diameter of the ring extension, so that the wrap spring rests on the outer circumference of the ring extension in the idle state. One end of the wrap spring is fixed against rotation on the fixed flange wall of the cable drum. The other end of the wrap spring, however, is coupled to an unlocking element that can be operated by hand. When the unlocking element is actuated, the other end of the wrap spring is adjusted in the sense of widening the wrap spring, so that the blocking of the cable drum in the winding direction is released and the cable drum can thus be rotated by a spring motor in the winding device. When the cable is pulled off, the wrap spring is twisted in the direction of its widening by the corresponding rotation of the cable drum as a result of the friction existing between the wrap spring and the outer circumference of the ring extension, and is thereby loosened at least to the extent that rotation of the cable drum in the pulling direction is possible. However, the wrap spring remains in contact with the circumferential surface of the ring shoulder, so that a corresponding frictional force must be overcome when the cable is pulled off.

Der Erfindung liegt die Aufgabe zugrunde, eine Kabelaufwickel­vorrichtung der gattungsgemäßen Art so auszubilden, daß das Bremselement beim Abziehen des Kabels keine der Abziehkraft entgegenwirkende Reibungskraft mehr verursacht.The invention is based on the object of designing a cable winding device of the generic type in such a way that the braking element no longer causes any frictional force opposing the pulling force when the cable is pulled off.

Die Lösung der gestellten Aufgabe gelingt durch die im Kenn­zeichen des Anspruches 1 angegebenen Merkmale.The problem is solved by the features specified in the characterizing part of claim 1.

Eine konstruktiv einfache Ausführungsform, die insbesondere mit bereits vorhandenen Ausführungsformen von Kabeltrommeln kombi­niert werden kann, besteht darin, daß das Löseelement an das Entriegelungselement angekoppelt ist. Bei dieser Lösungsmög­lichkeit brauchen außer der Ankopplung des Löseelementes keine Veränderungen an der Kabeltrommel durchgeführt zu werden.A structurally simple embodiment, which can be combined in particular with already existing embodiments of cable drums, consists in the release element being coupled to the unlocking element. With this solution, no changes need to be made to the cable drum except for the coupling of the release element.

Das Löseelement wird vorteilhafterweise als drehbar gelagerter doppelarmiger Hebel ausgebildet, der mit dem Ende seines einen Armes an dem Entriegelungselement und mit dem Ende seines anderen Armes an dem Kabel anliegt. Beim Abziehen des Kabels von der Kabeltrommel wird das Kabel gestrafft und der am Kabel anliegende Hebelarm entsprechend verschwenkt. Durch diese Ver­schwenkung wird das an dem anderen Hebelarm angekoppelte Ent­riegelungselement in Entriegelungsrichtung verstellt und damit das Bremselement vollständig von der Bremsfläche abgehoben, so daß keine Reibung mehr zwischen dem Bremselement und der Brems­fläche besteht.The release element is advantageously designed as a rotatably mounted double-armed lever, which rests with the end of one arm on the unlocking element and with the end of its other arm on the cable. When the cable is pulled off the cable drum, the cable is tightened and the lever arm attached to the cable is pivoted accordingly. As a result of this pivoting, the unlocking element coupled to the other lever arm is adjusted in the unlocking direction and thus the braking element is completely lifted off the braking surface, so that there is no longer any friction between the braking element and the braking surface.

Anhand eines in der Zeichnung dargestellten Ausführungsbei­spieles wird der Anmeldungsgegenstand nachfolgend näher be­schrieben. Es zeigt:

  • FIG 1 eine Kabelaufwickelvorrichtung in Draufsicht auf deren feststehende Flanschwand,
  • FIG 2 in schematischer Darstellung die Ankopplung eines Löseelementes an dem Entriegelungselement in der Stellung bei eingezogenem Kabel,
  • FIG 3 in schematischer Darstellung die Ankopplung eines Löse­elementes an dem Entriegelungselement in der Stellung während des Abziehens des Kabels von der Kabeltrommel,
  • FIG 4 in schematischer Darstellung die Ankopplung eines Löseelementes an ein auf den Umfang der Kabeltrommel wirkendes Bremselement.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
  • 1 shows a cable winding device in plan view of its fixed flange wall,
  • 2 shows a schematic representation of the coupling of a release element to the unlocking element in the position when the cable is drawn in,
  • 3 shows a schematic representation of the coupling of a release element to the unlocking element in the position during the pulling off of the cable from the cable drum,
  • 4 shows a schematic representation of the coupling of a release element to a brake element acting on the circumference of the cable drum.

Mit 1 ist die feststehende Flanschwand einer Kabelaufwickel­vorrichtung bezeichnet. An dieser Flanschwand 1 ist in bekannter Weise eine Kabeltrommel 2 drehbar gelagert und durch einen Federmotor 3 in Aufwickelrichtung antreibbar. Derartige Vorrichtungen werden üblicherweise mit einer Bremseinrichtung versehen, durch die ein ungewolltes Aufwickeln des von der Kabeltrommel 2 abgezogenen Kabels 4 verhindert wird. Bei der beispielhaft dargestellten Kabelaufwickelvorrichtung besteht die Bremseinrichtung aus einer am Außenumfang eines mit der Kabeltrommel 2 verbundenen Ringansatzes 5 angeordneten Schling­feder 6. Die Windungsrichtung der Schlingfeder 6 ist so gewählt, daß bei der dem Aufwickeln entsprechenden Drehrichtung ein Zusammenziehen der Schlingfeder und damit eine entsprechende Anpressung der einzelnen Windungen an den Ringansatz 5 erfolgt. Dadurch wird eine entsprechende Drehung der Kabeltrommel 2 blockiert.1 with the fixed flange wall of a cable winding device is designated. In a known manner, a cable drum 2 is rotatably mounted on this flange wall 1 and can be driven in the winding direction by a spring motor 3. Devices of this type are usually provided with a braking device, by means of which an unintentional winding up of the cable 4 pulled off the cable drum 2 is prevented. In the cable winding device shown as an example, the braking device consists of a wrap spring 6 arranged on the outer circumference of a ring extension 5 connected to the cable drum 2 individual turns on the ring approach 5 takes place. This blocks a corresponding rotation of the cable drum 2.

Mit ihrem einen Ende 7 ist die Schlingfeder 6 an einem entspre­chenden Widerlager 8 an der Flanschwand 1 arretiert. Das andere Ende 9 ist mit einem Entriegelungselement 10 verbunden, das verschiebbar an der Flanschwand 1 angeordnet ist und durch Krafteinwirkung, wie durch einen Pfeil 11 angedeutet, verscho­ben werden kann. Hierdurch wird das andere Ende der Schling­feder 6 entsprechend verschwenkt und dadurch eine Aufweitung der Schlingfeder 6 bewirkt. Damit wird die Blockierung der Kabeltrommel 2 in Aufwickelrichtung aufgehoben und der Feder­motor 3 kann die Kabeltrommel 2 in Aufwickelrichtung antreiben.With one end 7, the wrap spring 6 is locked to a corresponding abutment 8 on the flange wall 1. The other end 9 is connected to an unlocking element 10, which is arranged displaceably on the flange wall 1 and can be displaced by the action of force, as indicated by an arrow 11. As a result, the other end of the wrap spring 6 is pivoted accordingly, thereby causing the wrap spring 6 to expand. This blocks the blocking of the cable drum 2 in the winding direction and the spring motor 3 can drive the cable drum 2 in the winding direction.

Beim Abziehen des Kabels 4 von der Kabeltrommel 2 wird die Schlingfeder 6 durch die zwischen ihr und dem Ringansatz 5 bestehende Reibung in ihrer Aufweitungsrichtung etwas verdreht und damit die Blockierung aufgehoben. Das Kabel 4 kann von der Kabeltrommel abgezogen werden, wobei die Schlingfeder 6 aller­dings in Anlage an den Ringansatz bleibt und damit eine ent­sprechende Reibung und einen Abrieb an den Ringansatz 5 ver­ursacht. Dies kann vermieden werden, wenn beim Abziehen des Kabels 4 die Schlingfeder 6 vollständig von dem Ringansatz 5 abgehoben wird.When the cable 4 is pulled off the cable drum 2, the wrap spring 6 is twisted somewhat in its widening direction by the friction existing between it and the ring shoulder 5, and the blocking is thus removed. The cable 4 can be pulled off the cable drum, the wrap spring 6, however, remaining in contact with the ring shoulder and thus causing a corresponding friction and abrasion on the ring shoulder 5. This can be avoided if the wrap spring 6 is completely lifted off the ring extension 5 when the cable 4 is pulled off.

Um ein selbsttätiges und vollständiges Lösen des Bremselementes beim Abziehen des Kabels 4 von der Kabeltrommel 2 zu erreichen, ist gemäß der Darstellung in den FIG 2 und 3 ein doppelarmiger Hebel 12 als Löseelement vorgesehen, der um eine Achse 13 dreh­bar gelagert ist. Die Achse 13 kann an einem entsprechenden mit der Flanschwand 1 verbundenen Tragelement oder bei Einbau der Kabelaufwickelvorrichtung in ein Gehäuse an diesem Gehäuse angeordnet sein.In order to achieve an automatic and complete release of the braking element when the cable 4 is pulled off the cable drum 2, a double-armed lever 12 is provided as a release element as shown in FIGS. 2 and 3 and is rotatably mounted about an axis 13. The axis 13 can be arranged on a corresponding support element connected to the flange wall 1 or when the cable winding device is installed in a housing on this housing.

Mit dem Ende 14 seines einen Armes ist der doppelarmige Hebel 12 an dem Entriegelungselement 10 angelenkt. Mit dem Ende 15 seines andere Armes liegt der doppelarmige Hebel 12 über eine Rolle 16 an dem Kabel 4 an. Der Hebel 12 ist so angeordnet, daß in der Ruhestellung des Kabels 4 (FIG 2) von ihm keine Ver­stellkraft auf das Entriegelungselement 10 ausgeübt wird. Das Entriegelungselement 10 verbleibt somit der in der Stellung, in der die Kabeltrommel 2 durch die Schlingfeder 6 in Aufwickel­vorrichtung vollständig blockiert ist.With the end 14 of one arm, the double-armed lever 12 is articulated on the unlocking element 10. With the end 15 of its other arm, the double-armed lever 12 abuts the cable 4 via a roller 16. The lever 12 is arranged in such a way that in the rest position of the cable 4 (FIG. 2) no adjustment force is exerted on the unlocking element 10 by it. The unlocking element 10 thus remains in the position in which the cable drum 2 is completely blocked by the wrap spring 6 in the winding device.

Beim Abziehen des Kabels 4 von der Kabeltrommel 2 wird das Kabel 4 infolge der einwirkenden Zugkraft aus seiner Ruhelage in eine Schräglage bewegt (FIG 3) und dabei der anliegende Arm des Hebels 12 entsprechend verschwenkt. Über den anderen Arm des Hebels 12 wird dabei das Entriegelungselement 10 in Ent­riegelungsrichtung verschoben und damit das mit diesem gekop­ pelte andere Ende 9 der Schlingfeder 6 verschwenkt. Hierdurch wird die Schwingfeder 6 so stark aufgeweitet, daß sie nicht mehr an dem Ringansatz 5 anliegt. Damit ist die Kabeltrommel 2 beim Abziehen des Kabels 4 von einer entsprechenden durch die Schlingfeder 6 bewirkten Reibungskraft entlastet.When the cable 4 is pulled off the cable drum 2, the cable 4 is moved from its rest position into an inclined position as a result of the tensile force acting on it (FIG. 3), and the adjacent arm of the lever 12 is pivoted accordingly. About the other arm of the lever 12, the unlocking element 10 is shifted in the unlocking direction and thus that koped with it pelte other end 9 of the wrap spring 6 pivoted. As a result, the oscillating spring 6 is expanded so much that it no longer abuts the ring extension 5. The cable drum 2 is thus relieved of a corresponding frictional force caused by the wrap spring 6 when the cable 4 is pulled off.

In FIG 4 ist eine andere Ausführungsvariante einer Bremsein­richtung für eine Kabeltrommel 2 dargestellt. Diese Bremsein­richtung weist ein als verschwenkbare Schwinge 17 ausgebildetes Entriegelungselement auf, wobei an dem einen Ende 18 der Schwinge 17 eine gegen eine gehäusefeste Keilfläche bewegbare, am Außenumfang einer Kabeltrommelwand 20 anliegende Bremsrolle 21 verschiebbar angeordnet ist. Um eine vollständige Entlastung von Reibungskräften beim Abziehen des Kabels 4 zu erreichen, ist an dem zur Entriegelung betätigbaren anderen Ende 22 der Schwinge 17 wiederum ein doppelarmiger Hebel 12 (nur teilweise dargestellt) angelenkt. Die Anordnung des Hebels 12 sowie seine Betätigung beim Abziehen des Kabels ist die gleiche wie zuvor für die FIG 2 und 3 beschrieben. Die Schwinge 17 wird also beim Abziehen des Kabels 4 entgegen dem Uhrzeigersinn verschwenkt, so daß die Bremsrolle 21 von dem Außenumfang der Kabeltrommel­wand 20 abgehoben wird. Eine Reibung erfolgt damit nicht mehr.FIG. 4 shows another embodiment variant of a braking device for a cable drum 2. This braking device has an unlocking element designed as a pivotable rocker arm 17, a brake roller 21 which is movable against a wedge surface fixed to the housing and abutting the outer circumference of a cable drum wall 20 being displaceably arranged on one end 18 of the rocker arm 17. In order to achieve a complete relief of frictional forces when pulling off the cable 4, a double-armed lever 12 (only partially shown) is in turn articulated on the other end 22 of the rocker arm 17 which can be actuated for unlocking. The arrangement of the lever 12 and its actuation when the cable is pulled out is the same as previously described for FIGS. 2 and 3. The rocker arm 17 is thus pivoted counterclockwise when the cable 4 is pulled off, so that the brake roller 21 is lifted off the outer circumference of the cable drum wall 20. There is no longer any friction.
