Definitions

  • the present invention relates to a sweeper, in particular a hand sweeper or hand-held sweeper.
  • Sweepers for cleaning a substrate are known.
  • hand-held sweeping machines have established themselves in the commercial and private sector, which usually include a rotatably mounted brush roller and possibly so-called side brushes for sweeping edges and corners. While previous hand-held machines have translated the machine into a rotary motion of the sweeping brushes, this rotary motion is nowadays produced electrically by means of an electric motor.
  • a hand sweeper known with a housing, a hopper and a housing covered by the sweeping roller, which is rotatably mounted on a height adjustment about a rotation axis, wherein the height adjustment means of an adjusting mechanism about a parallel to the rotation axis aligned pivot axis is pivotable.
  • the adjusting mechanism has an adjustable about the pivot axis pivot arm, the protruding from the housing and is releasably lockable in different pivot positions.
  • the sweeper according to the invention comprises two support arms.
  • the support arms serve as a holder of a rotating drivable brush roller.
  • the brush roller is arranged substantially horizontally between two brush-side ends of the two support arms rotatable about an axis of rotation.
  • the support arms according to the invention are arranged freely pivotable about a substantially horizontally extending pendulum axis.
  • the pendulum bearing according to the invention of the brush roller carrying support arms allows a positional adjustment of the brush roller to any surface irregularities of the surface to be cleaned and compensation for wear of the bristles. If the brush roller encounters a bump on the ground during operation, it is pivoted or pushed upward by it. Due to the independent support of the two support arms is also a one-sided, i. oblique tilting of the brush roller possible. This ensures the greatest possible contact with the surface to be cleaned. By the pendulum bearing is guaranteed even when the brushes wear in that the contact between the sweeping or brush roller and the ground is always maintained.
  • the position of the pendulum axle can be selected such that the brush roller is lowered due to gravity to a surface to be swept.
  • a contact pressure of the brush roller can thus be preset to the surface to be cleaned.
  • the brush roller rests with its full weight (and that of the support arms) on the ground.
  • the pressure / Nachstell concept the brush roller on the surface to be cleaned can also be spring assisted.
  • the sweeping machine according to the invention may comprise at least one drive motor for driving the brush roller.
  • the drive motor can either be arranged stationary in the interior of the sweeper.
  • This variant would have the advantage that the adjusting force would be increased by the tensile force of the belt, which arises during a pendulum movement of the support arm.
  • the drive motor can also be arranged between the brush distal ends of the two support arms.
  • the support arm is designed as a holder for the drive motor and the drive motor moves in a pendulum movement of the support arm or the Support arms with. He thus has the function of the above-mentioned counterweight.
  • the invention is suitable for sweepers of any kind, both hand-held sweepers and sweepers with motor propulsion. It is also suitable for sweepers with or without side brush.
  • FIG. 1 shows a perspective view of a sweeping machine 10 according to the invention, as it is basically known in its external structure.
  • the sweeping machine 10 comprises a housing 102 and a handle 104 which is hinged to an upper side of the housing 102 and to the other end, not shown, of which a handle for guiding the sweeping machine 10 is attached.
  • the articulation of the stem 104 is effected by means of a suitable joint 106, e.g. Double joint or ball joint, which allows sufficient degrees of freedom for easy operation of the sweeper.
  • a snap-action receptacle 108 which securely receives the stem 104 in a folded-over rest position.
  • side brush 16 At two corners of the housing 102 of the sweeper 10 so-called side brush 16 can be seen, which rotate about a substantially vertical axis and serve for better sweeping and cleaning of edges, joints and corners. Wheels 112 are provided for advancing the sweeping machine 10 in one direction of operation at the two corners of the housing 102 opposite the side brushes 16.
  • a pressure switch 110 for actuating a drive motor 30 is provided to a (in the FIG. 1 unrecognizable) brush roller 12 and possibly the side brush 16 of the sweeper 10 to put in a rotational movement.
  • FIG. 2 shows in a lateral sectional view arranged in the interior of the housing 102 of the sweeper 10 according to the invention support arm 20.
  • support arm 20 In the illustration of FIGS. 2 and 3 in each case a support arm 20 can be seen; on the axisymmetric opposite side of the sweeper 10 is a corresponding second arm.
  • Each of the support arms according to the invention is arranged freely pivotable in the interior of the sweeper housing 102 about a substantially horizontally extending pendulum axis 26.
  • Freely pivotable in the context of the present invention means that the orientation of the support arm about the pendulum axis 26 is not regulated by adjusting handles, as known from the prior art, and / or in predetermined setting positions, but infinitely free due to the gravity of the brush roller he follows.
  • the pivoting function described can be supported by spring forces, as already mentioned above.
  • the drive motor is arranged stationary in the interior of the housing 102 and the pendulum axis corresponds to the upper suspension of the support arm at the end remote from the brush.
  • a counteracting the gravity of the brush roller spring loading could be provided to achieve a resting of the brush roller with a lower weight.
  • Another alternative could be to arrange the pendulum axis between the two Tragarmenden as in the embodiment shown in the figures and instead of the provided on the support arm drive motor or other counterweight down (ie, parallel to the rolling shear force) acting spring applied.
  • the pendulum axis between the two Tragarmenden as in the embodiment shown in the figures and instead of the provided on the support arm drive motor or other counterweight down (ie, parallel to the rolling shear force) acting spring applied.
  • each support arm has a brush-side end 22 and a brush-distal end 24. Between these two ends, the described pendulum axis 26 extends substantially perpendicular to the longitudinal extent of the support arm.
  • a brush roller 12 is arranged rotatably about a rotation axis 14.
  • the axis of rotation 14 extends substantially parallel to the pendulum axis 26. In principle, an oblique arrangement of the axis of rotation 14 would be conceivable, so that it is not parallel to the pendulum axis 26, but still horizontally.
  • a drive motor 30 for driving the brush roller 12 is arranged.
  • the drive motor 20 may - as in the illustrated embodiment - be mounted directly on the support arm 20.
  • the drive motor 30 may be arranged along an axis between the two support arms.
  • the drive motor 30 is, for example, a small and relatively light electric motor (for example battery-operated) whose power is dimensioned such that it can set the brush roller 12 and the side brushes 16 in a rotational movement.
  • the transmission of the driving force from the drive motor 30 to the brush roller 12 and the side brushes 16 takes place by means of a power transmission device, which is also arranged directly on the support arm 20 in the illustrated embodiment.
  • the power transmission device comprises a first pinion 40, which is arranged on the brush-distal end 24 on an output shaft 32 of the drive motor 30.
  • the drive motor 30 may in particular be arranged such that its output axis 32 extends substantially perpendicular to the longitudinal extension of the support arm 20.
  • the power transmission device comprises a second pinion 42, which is arranged on the brush-side end 22 of the support arm 20 on the rotational axis 14 of the brush roller 12.
  • a belt 41 timing belt
  • the second pinion 42 may have a larger diameter than the first pinion 40.
  • the power transmission device comprises a worm drive 44 (see. FIG. 3 ).
  • the side brushes 16 are inserted and supported on the respective brush-side end 22 of the support arm 20 in a receptacle 28 provided for this purpose by means of a shank 18 in a direction substantially perpendicular to the axis of rotation 14 of the brush roller 12.
  • the side brushes 16 lie with their substantially radially projecting bristles 19 on a substrate to be cleaned. They assume a slight inclination with respect to the vertical.
  • the worm drive 44 is driven by the drive motor 30 via the pinion 42 and the rotation axis 14. The rotational movement of the worm drive 44 is transmitted to the side brush 16 by engagement with corresponding formations 46 on the shaft 18.
  • the inventive design of a sweeper with a substantially horizontally extending pendulum axis freely pivoting support arms on which both the brush roller and possibly the side brushes are mounted allows in any operating condition improved contact or resting the bristles of the brush roller and the side brush on the to be cleaned underground.
  • the brush and broom position adapts easily by pivoting the support arms.
  • the support arms also carry the at least one drive motor. Due to the separate arrangement of the swing axle from the drive axle of the engine, i.
  • the arrangement of the pendulum axis wipe the brush-side end and the brush-distal end of the support arm, a balancing of the support arms taking into account the weight of the brush roller and the side brushes on the one hand and the at least one drive motor on the other hand done so that the bearing force of the bristles on the surface to be cleaned optimized becomes.
