Definitions

  • the invention relates to a floor sweeper according to the preamble of claim 1.
  • the invention has for its object to provide a floor sweeper of the type mentioned, in which such disadvantages are avoided and a permanent height adjustment of the roller brush is possible without affecting the drive of the roller brush by the impellers and losses in the sweeping performance in to accept one or the other end position.
  • this object is achieved by the characterizing features of claim 1. Since the two wheel arches are suspended from the legs of the U-shaped adjustment bracket with wheel arch holders, the wheel arches and thus the drive wheels can adapt to all unevenness of the floor. The distance between the roller brush and the dirt collector remains constant, while the distance to the floor is always in the most effective area.
  • the wheel arch can consist of sheet metal and have a U-shaped cross-section, the two having openings for the drive wheels to receive through between the side legs for inserting the drive wheels. With the insertion of the axle journals, the two wheels are held in a simple manner in the inexpensive wheel housing.
  • the axle journals can consist of the angled ends of an approximately U-shaped spring wire bracket which is held on the outside of one of the two side legs of the wheel arch.
  • the two journals for the storage of the two drive wheels in a wheel arch are thus connected to one another via an approximately U-shaped spring wire bracket, so that when the U-shaped spring wire bracket is attached, both drive wheels are simultaneously held in the wheel arch.
  • the apex part and the arches of the U-shaped wire bracket provided between the apex part and the two legs can rest on the outside against punched-out tongues of the wheel arch consisting of sheet metal. As a result, a displacement of the U-shaped spring wire bracket on the side leg of the wheel arch is avoided.
  • the two legs of the U-shaped spring wire bracket can be inclined towards one another with their ends having the axle journals, the openings in the side legs of the wheel arch exceeding the diameter of the axle journals with their clear width.
  • the axle journals are easily supported with a large clearance in the openings in the side legs of the wheel arch, so that when the two drive wheels are pressed against the floor to be cleaned by the inclined legs of the U-shaped spring wire bracket, the drive wheels against the between the Both drive wheels arranged pinions of the roller brush can be pressed.
  • the friction between the drive wheels and the pinions of the roller brush is increased.
  • the wheel arch which has a U-shaped cross-section, can have an opening in the middle in its connecting part for inserting the wheel arch holder made of plastic, the wheel arch holder engaging in the opening with two resilient legs having mutually facing latching lugs.
  • the wheel arch holder can be held in a particularly simple manner by simply pressing it into the wheel arch.
  • the wheel arch holder can have an arm which is angled to the side and then downwards and which, with its free end, extends over the arm U-shaped spring wire bracket adjoins the outside of the side arm of the wheel arch and is supported with a molded projection against the side arm of the wheel arch. With this wheel arch holder, the U-shaped spring wire clip can thus be secured against being pulled out of the wheel arch in a simple manner.
  • the wheel arch holder can have an open to the side, approximately C-shaped bracket for clipping onto the leg of the U-shaped adjustment bracket.
  • the wheel arch can be connected to the adjustment bracket in a simple manner by simply clipping onto the leg of the U-shaped adjustment bracket.
  • the clear width of the receptacle of the C-shaped bracket can increase towards the ends.
  • the C-shaped bracket lies only with its central region against the leg of the U-shaped adjusting bracket and can oscillate, so that the pivoting movement of the U-shaped adjusting bracket can be converted into a straight vertical movement of the wheel arch.
  • the wheel arch holder can be guided on the one hand with a pin formed on the back of the approximately C-shaped bracket and on the other hand with the back of the molded arm on the side surfaces of the housing recess. As a result, the wheel arch is guided in a simple manner for the vertical movement in the housing recess.
  • Vertical ribs for guiding the wheel housing can be formed on the side surfaces of the housing recess. As a result, the wheel arch is also easily guided for vertical movement in the housing recess.
  • the U-shaped adjustment bracket carrying the wheel arch can run approximately parallel to the floor to be cleaned above the wheel arches, with a downwardly bent pin attached to the center of the cross part of the adjustment bracket, against which the adjustable wedge surface engages.
  • a downwardly bent pin attached to the center of the cross part of the adjustment bracket, against which the adjustable wedge surface engages.
  • the wedge surface cooperating with the cranked pin of the adjusting bracket can be provided on the free end face of a rotatable tube which is rotatably mounted in the housing and has an actuating handle which protrudes from the top of the housing.
  • the wedge surface can be adjusted by the operator simply by turning the actuating handle, and the roller brush can thus be adjusted in height.
  • the cooperating with the U-shaped adjustment bracket can be formed by an attack against the underside of the cross part, approximately V-shaped leaf spring, which is supported with its central part against the partition walls of the housing and with its two legs against the cross part of the U-shaped adjustment bracket is present.
  • the adjustment bracket is non-positively held against the adjustable wedge surface in a simple and reliable manner, so that any set height position of the roller brush is also maintained.
  • the floor sweeper 10 shown in the drawing consists of a housing 11.
  • the housing 11 serves on the outside for receiving a handle bracket 12, on which in turn a handle-like handle 13 is attached for the reciprocating movement of the floor sweeper over the floor to be cleaned.
  • the housing 11 serves to receive sweeping brushes and the impellers used to move the device over a floor surface and to drive the sweeping brushes.
  • a roller brush 14 is first provided, which extends transversely to the intended direction of movement. For the rotation of the roller brush 14 relative to the floor to be cleaned, they are assigned to the ends of the axis 15 pinions 16, which are frictionally operatively connected to the drive wheels 17.
  • the drive wheels 17 are mounted in pairs in a manner to be explained in the housing 11.
  • roller brush 14 can only work up to a certain distance from the side wall regions of the floor sweeper 10, additional brushes 18 are provided for detecting the side wall regions, with the aid of which the side regions lying outside the range of action of the roller brush 14 can also be detected, as a result of which also a complete one Cleaning the floor along heels and walls as well as in corner areas is possible.
  • an additional brush 18 is arranged in each of the front corner areas of the floor sweeper, such that they are rotatable about an essentially upright axis and with it rem pot-shaped, i.e. radially outward and un th arranged bristle ring overlap the effective area of the roller brush 14 on the one hand and the side wall and front wall area of the housing 11 on the other.
  • the two additional brushes 18 are coupled in a drive-locking manner with drive wheels 19 arranged between them.
  • the bearing bracket 20 is formed by an approximately U-shaped clip made of spring steel and can be positively attached with the two legs 21, 22 of the U-shaped clip to a downwardly directed wall part 23 of the housing 11. With these two bearing clasps 20, the roller brush 14 can be easily mounted and removed in the housing 11.
  • the two pinions 16 of the roller brush 14 are each assigned two drive wheels 17.
  • one drive wheel 17 is provided in front of the roller brush 14 and the other drive wheel 17 is provided behind the roller brush 14.
  • the drive wheels 17 have a tread 25 formed by an attached rubber ring 24, which tread 25 presses against the pinion 16 in a manner yet to be described, so that the drive wheels 17 are drivingly coupled to the pinion.
  • the roller brush 14 thus rotates. Since the drive wheels 17 have a larger diameter than the pinions 16, the roller brush rotates at a higher speed.
  • the two drive wheels 17 belonging to a pinion 16 are each mounted in wheel housings 26. 6 to 9 such a wheel arch is shown in more detail.
  • the wheel housing 26 is made of sheet metal and has a U-shaped cross section, the two drive legs 17 between the side legs 27 receiving openings having openings 28 for pushing through the axle journals 29 carrying the drive wheels 17.
  • the axle journals 29 are formed by the angled ends of an approximately U-shaped spring wire bracket 30, which is held on the outside of one of the two side legs 27 of the wheel arch 26.
  • the apex part 31 and the arches 33 of the U-shaped spring wire bracket 30 provided between the apex part 31 and the two legs 32 lie on the outside against punched-out tongues 34, 35 of the wheel housing 26 made of sheet metal.
  • the spring wire bracket 30 can thus be inserted from the side into the wheel housing 26 in a simple manner, the axle journals 29 reaching through the openings 28 of the side legs 27 of the wheel housing 26 and the drive wheels 17. Moving the spring wire bracket 30 against the tongues 34 and 35 prevents the spring wire bracket 30 from moving.
  • the two legs 32 of the U-shaped spring wire bracket 30 run towards one another with their ends having the axle journals 29, the openings 28 provided in the side legs 27 of the wheel arch 26 having the clear width of the diameter of the Axle 29 surpass.
  • the wheel arch 26 which has a U-shaped cross section, has an opening 37 in the middle in its connecting part 36 for inserting a wheel arch holder 38 made of plastic.
  • the wheel arch holder 38 engages with two resilient legs 40, which have mutually facing locking lugs 39, into the opening 37.
  • the wheel arch holder 38 can thus be fastened to the wheel arch 26 by simply inserting it into the opening 37.
  • the wheel arch holder 38 has an arm 41 which is angled to the side and then downward and which, with its free end, lies over the U-shaped spring wire bracket 30 which bears against the outside of the side arm 27 of the wheel housing 26 and lies against the side arm with a molded projection 42 27 of the wheel arch 26 supports. After inserting the wheel arch holder 38 into the opening 27 in the connecting part 36 of the wheel arch 26, the approximately U-shaped spring wire bracket 30 is thus secured against lateral pulling out.
  • the wheel arch holder 38 has an approximately C-shaped bracket 43 which is open to the side and can be clipped onto the leg 44 of a U-shaped adjusting bracket 45.
  • the adjustment bracket 45 is shown in more detail in FIG. 2.
  • Fig. 2 shows schematically the height adjustment of the wheel arches 26 and thus the drive wheels 17.
  • the inside width of the receptacle 46 of the C-shaped bracket 43 increases towards the ends.
  • the wheel arch 26 is held in a pendulum manner on the leg 44 of the U-shaped adjustment bracket 45, so that when the adjustment bracket 45 is pivoted, both drive wheels 17 always abut against the floor to be cleaned.
  • the drive wheels 17 and thus the wheel arch 26 can thus also adapt to all unevenness in the floor.
  • the wheel arch holder 38 is guided on the one hand with a pin 47 formed on the back of the approximately C-shaped bracket 43 and on the other hand with the back of the integrally formed arm 41 on the side faces 48 of a housing recess 49 which is provided for receiving the wheel housing 26 in the housing 11.
  • a housing recess 49 which is provided for receiving the wheel housing 26 in the housing 11.
  • the wheel housing 26 is guided in the housing recess 49 of the housing 11 so that it can be displaced in the vertical direction.
  • the U-shaped adjusting bracket 45 carrying the wheel arches 26 runs over the wheel arches 26 approximately parallel to the floor to be cleaned, a downwardly cranked pin 52 being attached centrally to the transverse part 51 of the adjusting bracket 45.
  • An adjustable wedge surface 53 engages against the cranked pin 52. With this adjustable wedge surface 53, the adjustment bracket 45 is pivoted.
  • the U-shaped adjustment bracket 45 is pivotally mounted in corresponding bearings 55 of the housing 11 with bends 54 formed on the free ends of the legs 44.
  • the wedge surface 53 cooperating with the cranked pin 52 of the adjustment bracket 45 is provided on the free end face of a rotatable tube 56 which is rotatably mounted in the housing 11.
  • a downwardly open receptacle 57 is provided in the housing 11, into which the rotatable tube 56 is inserted.
  • the bottom 58 of the receptacle 57 has an opening 59 into which a tubular extension 60 of the rotatable tube 56 engages.
  • the rotatable tube 56 has a central opening 61, into which a projection 63 of an actuating handle 64, which has locking lugs 62, engages.
  • the rotatable tube 56 is thus to be inserted into the receptacle 57 from below and then the actuating handle 64 is pressed on from above.
  • the operating handle 64 is provided in an opening 65 in the top of the floor sweeper so that the operator can rotate the operating handle by gripping the rib 66.
  • the rotatable tube 56 is simultaneously rotated with the wedge surface 53 provided thereon, which presses on the cranked pin 52 of the adjusting bracket 45.
  • the height adjustment of the wheel housings 26 and thus the drive wheels 17 results in a height adjustment of the roller brush 14 relative to the ground, which is fixedly mounted in the housing 11 of the floor sweeper 10.
