Definitions

  • the invention relates to a floor care device according to the preamble of claim 1.
  • the object of the invention is based on the object of specifying a generic floor care device in which the structure is simplified and the production costs are reduced in such a way that an optimal constant work performance is achieved in the case of brush wear.
  • the construction of a generic floor care device is simplified, which permits cost-saving production. Nevertheless, the floor care device works with optimal, constant work performance.
  • the height of the brush body axis of rotation depends on the tension of the drive belt. E.g. the tension of the drive belt is lower, resulting from insufficient brush pressure, the rocker swivels and brings the brush body axis of rotation closer to the ground to be worked. If the brush pressure is too great, on the other hand, the tension of the drive belt increases, which also displaces the rocker arm in such a way that the axis of the brush body moves away from the carpet.
  • the swing arm-side deflection point which comes into contact with the floor-side train run, is used to control the swing arm. Different tensile stresses on this lead to a corresponding pivoting of the rocker.
  • the deflection point is designed as a tensioning roller. This design works very sensitively and brings good work results with reduced friction.
  • the rocker arm is loaded by an adjustable spring against the torque resulting from the tension of the drive belt.
  • the spring is designed as a torsion spring and engages a curved toothing of the rocker arm via a toothed wheel. This results in a favorable damping effect, particularly when the floor care device is switched on.
  • the gear drive does not adversely affect the swing arm mounting.
  • the limit switch is used to stop the motor if the drive belt is too tight - for example, caused by excessive brush pressure or a blockage.
  • the user of the floor care device thus has the option of eliminating the malfunction or setting a different brush pressure value. This measure protects the motor against overload with particularly simple means.
  • FIGS. 1-3 An exemplary embodiment of the invention is explained below with reference to FIGS. 1-3.
  • 1 shows, on an approximately natural scale, in dash-dot lines, a housing of a carpet sweeping machine which has brush bodies which are cantilevered on both sides of the drive point, the bristles not being illustrated in a brush body for the purpose of simplified illustration;
  • Fig. 2 shows a schematic representation of a longitudinal section through the brush body drive in the rest position
  • Fig. 3 is a representation corresponding to FIG. 2, namely when the carpet sweeper is in operation with the rocker moved and thus the brush body axis of rotation raised.
  • the carpet sweeper has a dash-dotted, approximately T-shaped housing 1.
  • An electric motor 2 is accommodated in the T-web, while the T-bar 3 accommodates brush bodies 4, 5 which are exposed on both sides of the drive point.
  • Bristles 6 are provided in a helical arrangement on the brush bodies 4, 5.
  • an end ring consisting of bristles 7 is located on the end of the brush bodies.
  • the brush bodies 4, 5 sit on a brush body axis of rotation 8, which carries a drive pulley 9 in the center.
  • the brush body axis of rotation 8 passes through the end of a rocker arm 10 of a rocker arm 12 rotatably mounted about a pivot pin 11 on the housing side.
  • the other swing arm 14 is equipped with curved teeth 15 which are concentric with the journal 11.
  • a stepped end 16 adjoins the curved toothing.
  • the two layers of the end are also connected to one another by a bridge 17.
  • a drive belt 19 is placed around the drive wheel 18 of the electric motor 2 and the pulley 9.
  • the pulling run 19 ′ leading from the drive wheel 18 to the pulley 9 is buckled by a tensioning roller 20 mounted on the swing arm 14.
  • the tensioning roller 20 is seated on a pin 21, which runs in a vertical slot 22 of the swing arm 14 and is fastened there at a certain height.
  • a tensioning roller 23 is also assigned to the counter-running run 19 ′′.
  • the curved toothing 15 interacts with a gear 25.
  • the latter is supported on the one hand in a bearing block 26 of the housing 1 and on the other hand in a drum 27, which in turn continues in a journal 28 mounted on the housing.
  • a torsion spring 29 engages, which in turn is fixed to the inner wall of the drum 27.
