Definitions

  • the invention relates to a cable winder according to the preamble of claim 1.
  • Such a device is known from DE-0S 33 16 977.
  • 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 is coupled to an unlocking element that can be operated by hand.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the cable is pulled off the cable drum, the cable is tightened and the lever arm attached to the cable is pivoted accordingly.
  • 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.
  • 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.
  • 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.
  • the wrap spring 6 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.
  • 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.
  • the wrap spring 6 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.
  • 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.
  • the double-armed lever 12 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.
  • 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.
  • 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.
  • 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
