Definitions

  • the invention relates to a cable winder for vacuum cleaners, which unwinds and unwinds a cable on a spring-loaded cable drum.
  • Such cable winders are generally known in vacuum cleaners. Cable winders are also known which are additionally equipped with centrifugal weights which, using the centrifugal force, brake the rotational speed when the cable is pulled in and thus ensure a uniform pull-in speed with a certain tolerance. Since these cable winders are spring-loaded, care must be taken to ensure that when the cable is pulled out, the spring does not immediately pull it back again. This can be done using a brake on the cable. The cable is held in place by a clamping device and can only run back again by loosening this clamping device. However, this has the disadvantage that the cable is also stressed by the clamping. The cable drum can also be braked, for example FR-A-2.175.037. Such a brake works on the principle of the friction brake and when pulling out the cable, the pulling force should be greater than the frictional force of the brake. This force must be applied by the user. This is also disadvantageous.
  • centrifugal weights are activated when you pull out. Although they do not brake as strongly due to the slow pull-out speed, pulling out the cable is always associated with rattling noises.
  • the object of the invention is to design a cable winder so that it can be pulled out without loading and unloading a braking device.
  • the object is achieved by the features of claim 1. Due to the configuration according to claim 2, the flyweights are advantageously not in operation when the cable is pulled out.
  • Fig. 1 shows a cable drum (1) in a schematic manner. It consists of the winding base (2) and the side walls (3 and 4). Wrapping base (2) and side wall (4) form an integral part. In this case, the side wall (4) and the winding base (5) are firmly connected to the axle (5) and this is rotatably mounted in the housing (6).
  • a part (7) of the freewheel is fixedly arranged on the axis (5). This part (7) engages in holes (8) on the side part (3) which is rotatably arranged on the axis (5).
  • This freewheel is drawn out enlarged in FIG. 3.
  • the part (7) has arms (9) which engage in holes (8) on the side part (3) with elevations at their end (10) (elevations are not shown).
  • the side part (3) carries two centrifugal brake weights (11 and 12) according to FIG. The operation is explained using the centrifugal brake weight (11).
  • the centrifugal brake weight (11) is rotatably mounted about the axis (13). It has an elongated hole (14) which, in connection with the stop (15), permits limited pivoting.
  • the tension spring (16) pulls the centrifugal brake weight (11) into a position in which the nose (17) is removed from the surface (18), which is shown here as it is on the housing (6) from FIG. 1 is lifted off.
  • the heavy part (19) is moved outwards by centrifugal force, and the nose (17) brakes more or less strongly on the surface.
  • the function of the cable drum according to the invention is explained with reference to FIG. 1.
  • the side wall (3) is held by the brake (20). If the length of the cable (22) (which is only partially shown due to the clarity of the drawing) is extended, the side wall (5) with the winding base (2) moves in the direction A. Since both are arranged firmly on the axis (4) are, this also turns in this direction, and the part 7 would run free. Ie, the cable (22) could be pulled out, and the side wall (3) would stand still. When the cable (22) is pulled out, however, the return spring (21) tightens at the side wall (4) and, when the tensile force on the cable (22) decreases, tries to turn it back in the direction E.
