Definitions

  • the invention relates to a floor care device according to 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 optimum, consistent work performance is achieved in the case of brush wear.
  • the height of the brush body axis of rotation depends on the tension of the drive belt. Is z. B. the tension of the drive belt less, resulting from too little brush pressure, so the rocker pivots and thereby brings the brush body axis of rotation in a closer proximity to the ground to be worked. If the brush pressure is too high, on the other hand, increases the tension of the drive belt, whereby the rocker is also displaced such that the brush body axis of rotation moves away from the carpet.
  • the swing arm-side deflection point which comes into contact with the floor-side draft strand, 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 with 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 gear. This results in a favorable damping effect, in particular when the floor care device is switched on.
  • the gear drive does not adversely affect the swing arm mounting.
  • the counter-running run of the drive belt is also loaded by a tension roller of the swing arm.
  • the setting of the different tension of the drive belt is facilitated in that the adjustable spring is assigned a display scale.
  • the rocker in the end regions of its pivoting movement acts on the one hand on a limit switch and on the other hand strikes against stops.
  • the latter ensure that the rocker does not leave its intended position even in the rest position.
  • the limit switch is used so that - for example, if the drive belt is too tight. caused by excessive brush pressure or a blockage that stops the motor.
  • 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.
  • 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 housing-side pivot pin 11.
  • the rocker arm is double-layered in such a way that the rocker arm 10 is connected at the end by a ring section 13 which partially overlaps the drive pulley 9.
  • the other swing arm 14 is equipped with curved teeth 15 which are concentric with the journal 11.
  • a stepped end 16 adjoins the arch teeth.
  • 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 ′′. This is rotatably mounted about a pivot 24 on the swing arm.
  • 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.
