Definitions

  • the invention relates to a floor sweeper according to the preamble of claim 1.
  • GB-A-638 541 also shows a roller brush holder via resilient bearing clips. Both versions are bearing clasps fixed to the housing via rivets or screws. The roller brush is held by a pin on the bearing clip, which engages in a hole in the roller brush axis. This has the disadvantage that the cross section of the roller brush axis is weakened. In addition, such a design is only practical with wooden axis brushes. The wire axis brushes commonly used today cannot be used easily with such a solution. Since the resilient leg of the bearing bracket is no longer secured with the bearing pin, the roller brush can be pulled out in the event of an unfavorable load.
  • the object of the invention is therefore to provide a floor sweeper with bearing clips, in which a safe storage of roller brushes with a wire axis is possible, and in which a simple assembly and above all disassembly of the roller brush is guaranteed.
  • the tubular bearing mount and the clamped mounting of the U-shaped bracket on a wall part make assembly particularly easy.
  • the roller brush can be preassembled with the two U-shaped brackets, so that the entire unit then only has to be clipped onto the two downward-facing wall parts.
  • wire roller brushes and wood axis brushes are held equally well. It is still easy to dismantle for repairs.
  • the cylindrical bearing end of the roller brush can be formed by a stepped shoulder of a pinion provided on the roller brush and connected to the impellers in a drive-locking manner.
  • the cylindrical bearing end of the roller brush is formed in a simple manner by a stepped shoulder of a pinion, which is present anyway for the drive connection of the roller brush to the impellers.
  • the U-shaped bracket can have the integrally formed tubular bearing receptacle on the inside of one leg, while the second leg is provided with a recess extending from its free end for the passage of the bearing receptacle.
  • the tubular bearing receptacle is molded onto one leg in a simple manner, as a result of which simple manufacture is achieved.
  • the tubular bearing receptacle extends through the space between the two legs, so that little space is required for the tubular bearing receptacle.
  • the outer side of the leg having the tubular bearing receptacle can rest against an annular shoulder formed by the offset shoulder of the pinion.
  • the roller brush is also secured in a simple manner against axial displacement in the two bearing clips.
  • the leg which has the cutout for the passage of the bearing receptacle can have obliquely outward bends at its free end to form an insertion bevel. With this insertion bevel formed by obliquely outward bends, the placement of the U-shaped bracket on the wall part of the housing is facilitated.
  • the leg having the tubular bearing receptacle can be somewhat longer than the second leg and, at its free end, have an inward, right-angled bend for engaging in a recess in the housing wall engaging in the U-shaped bracket. The engagement of this inward, right-angled bend in a recess in the housing wall prevents the U-shaped bracket from being pulled off the wall part of the housing.
  • the inward, right-angled bend of the first leg, with its side surface facing the apex part, can rest against a shoulder of the housing wall. As a result, the U-shaped bracket is secured against being pulled off.
  • the U-shaped clamp After being clipped onto the wall part of the housing with the tubular bearing receptacle, the U-shaped clamp can rest against the end wall of a downwardly open recess in the wall part of the housing. By this engagement of the tubular bearing receptacle in the downwardly open recess of the wall part of the housing, the U-shaped clamp is secured against lateral displacement and against further pressing.
  • the U-shaped clip can have an opening in its apex for inserting a screwdriver or the like which serves to spread the legs apart.
  • a screwdriver or the like which serves to spread the legs apart.
  • 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 the turn of which a handle-like handle 13 for the reciprocating loading movement of the floor sweeper is attached to 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 with respect to the floor to be cleaned, they are assigned to the ends of the axis 15 Ritzet 16, which are frictionally operatively connected to drive wheels 17.
  • the drive wheels 17 are mounted in pairs in the housing 11.
  • roller brush 14 can only work up to a certain distance from the side wall areas of the floor sweeper 10, additional brushes 18 are provided for detecting the side wall areas, with the aid of which the side areas outside the effective area of the roller brush 14 can also be detected, thereby also making 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 regions of the floor sweeper 10, in such a way that they can be rotated about an essentially upright axis and, with their cup-shaped, that is to say radially outward and downward, bristle ring, the effective range of the roller brush 14 on the one hand and the side wall and front wall area of the housing 11 overlap on the other.
  • the two additional brushes 18 are coupled in a drive-locking manner with drive impellers which are not shown in detail and are arranged in between.
  • the bearing bracket 19 is formed by a U-shaped bracket 20 made of spring steel and can be positively attached with the two legs 21, 22 to a downwardly directed wall part 23 of the housing 11.
  • the U-shaped bracket 20 has a molded, tubular bearing receptacle 24 on the inside of one leg 21.
  • the second leg 22 of the U-shaped bracket 20 is provided with a recess 25 extending from its free end for the passage of the bearing receptacle 24.
  • the leg 22 having the recess 25 for the passage of the bearing receptacle 23 has at its free end obliquely outwardly angled portions 26 to form an insertion bevel 27. With this lead-in bevel 27, the U-shaped bracket 20 is made easier to attach to the downwardly directed wall part 23 of the housing 11.
  • the distance between the two legs 21, 22 of the U-shaped bracket 20 decreases somewhat from the apex part 28 to the free ends of the legs 21, 22. As a result, the two legs 21, 22 bear against the downwardly directed wall part 23 of the housing 11 with prestress.
  • the leg 21 which has the tubular bearing receptacle 24 is somewhat longer than the second leg 22 and has at its free end an inwardly directed, right-angled bend 29 for engaging in a recess 30 in the housing wall 23 engaging in the U-shaped bracket 20. This prevents accidental loosening in a simple manner.
  • the inward, right-angled bend 29 of the first leg 21 of the U-shaped bracket 20 lies with its side surface 31 directed towards the log 28 against a shoulder 32 of the housing wall 23.
  • the offset shoulder 32 is formed by the recess 30.
  • the roller brush 14 When installing the roller brush 14, the two U-shaped brackets 20 are to be placed on the ends of the roller brush 14.
  • the roller brush 14 has offset shoulders 33 on the pinions 16.
  • the offset lugs 33 of the pinion 16 thus form cylindrical bearing ends which engage in the bearing receptacle 24 of the U-shaped brackets 20.
  • the roller brush 14 is thus rotatably supported in the two U-shaped brackets 20. These are then pressed together with the roller brush 14 arranged therein onto the wall parts 23 of the housing 11. The assembly is very easy.
  • the axis 15 of the roller brush 14 consists of two wires 35 twisted together, between which the bristles, not shown, are clamped. The free ends of the twisted wires 35 engage in a recess 36 of the pinion 16.
  • the axis 15 is formed of wood, in which individual tufts of bristles, not shown, are used. The free end of the wooden axis 15 is also inserted into a recess 36 of the pinion 16.
  • the U-shaped clamp 20 After being clipped onto the wall part 23 of the housing 11, the U-shaped clamp 20 rests with the tubular bearing receptacle 24 against the end wall 37 of a recess 38 of the wall part 23 of the housing 11 which is open at the bottom. This also prevents the U-shaped bracket 20 from slipping laterally after being placed on the downwardly directed wall part 23 of the housing 11.
  • the downward-facing wall part 23 of the housing 11 also has lateral ribs 39 which bear against the sides of the U-shaped bracket.
  • the U-shaped clip 20 has an opening 40 in its apex part 28 for inserting a screwdriver or the like which serves to spread the clip legs 21, 22 apart. This spreading of the legs 21, 22 with a screwdriver or the like means that the U-shaped clamp is removed and thus one Disassembly of the roller brush 14 possible in a simple manner.
