  • the invention has for its object to provide a floor sweeper of the type described in the introduction, in which such disadvantages are avoided and the operation and in particular the removal and emptying of the dirt collecting container is made considerably easier.
  • this object is achieved in that the two dirt collecting containers are connected to one another and have a common upper side, in which approximately one in the middle.
  • the part to be grasped by the operator and to be moved to a limited extent in the lifting direction is provided, which moves the resilient locking device into the release position when moving in the lifting direction.
  • Removing and inserting the combined two dirt collection containers is particularly easy to carry out.
  • a trough can be formed in the common upper side of the two dirt-collecting containers connected to one another, in which a pivoting lever is arranged, which covers the trough except for an engaging opening and forms the part which can be moved in the lifting direction.
  • the part which can be moved in the lifting direction is thus formed by a swivel lever which is provided in a recess on the top of the dirt collecting container, so that in the operating
  • the pivot lever can have an approximately U-shaped configuration, the apex part of which is plate-shaped and covers the trough except for an engagement opening and can be gripped by the operator with his fingertips, while the two legs of the approximately U-shaped pivot lever cover the upper wall of the dirt collecting container reach through and are mounted with their free ends on the underside of the upper wall pivotable about a horizontal axis.
  • the trough provided in the top of the dirt collecting container is covered by the plate-shaped apex part of the swivel lever up to an engagement opening, so that the operator can reach under the plate-shaped apex part of the swivel lever with his fingertips and lift it in the lifting direction of the dirt collecting container at the same time the locking device is moved into its open position.
  • the two legs of the approximately U-shaped pivot lever are pivotally mounted on the inside of the upper wall of the dirt collecting container in order to enable the pivoting movement of the pivot lever.
  • the two legs of the approximately U-shaped pivot lever can be formed by webs projecting vertically downwards and the underside of the plate-shaped apex part can be formed.
  • the shaping of the two webs forming the legs and projecting vertically downward on the underside of the plate-shaped apex part achieves a strong construction which can withstand all loads.
  • the two legs of the approximately U-shaped pivot lever can be formed with free ends on the sides facing one another, which engage in downwardly projecting wall parts formed in bearing bores from the upper wall of the dirt collecting container. This makes the swivel lever more reliable _ 1 ⁇ _
  • the pivoting lever which can be pivoted to a limited extent, can rest in the basic position with a part of the apex part against the upper side of the upper wall of the dirt collecting container and in the raised position with the legs against the underside of the upper wall of the dirt collecting container. As a result, reliably acting end limits are assigned to the pivot lever.
  • the resilient locking device securing the dirt collecting container in its operating position can be formed by a spring wire which is arranged on the underside of the upper wall of the dirt collecting container, extends parallel to the pivot axis of the pivoting lever and with its two protruding from the side walls of the dirt collecting container Ends engages in corresponding recesses of the housing and has a U-shaped bend formed in the central region for resilient inward movement of the ends protruding from the side walls of the dirt collecting container.
  • Area provided U-shaped arc is also formed from the spring wire, the spring wire is automatically returned to the operating position.
  • the apex part of the approximately U-shaped pivoting lever can have, on its underside, two approaches having inclined surfaces lying against the mutually facing outer sides of the two pivoting levers of the U-shaped arch of the spring wire. With these two approaches, which have inclined surfaces, one is
  • the two downward-facing lugs can have end stops for the spring wire formed at their free ends by mutually directed extensions. With these end stops for the spring wire, an unintentional jumping off of the
  • the spring wire forming the resilient locking device can have at its two free ends obliquely downward and inward angled portions which merge into inward angled portions.
  • the oblique downward and inward angled bends at the free ends of the spring wire ensure that the dirt collecting container is simply inserted into the housing of the floor sweeper, since the angled downward and inward bends act as inclined surfaces that act on the edges of the Hit the housing recess so that when the dirt collecting container is pressed into the housing of the floor sweeper, the ends of the spring wire are pressed inwards.
  • FIG. 1 shows a floor sweeper according to the invention in a diagrammatic representation
  • Fig. 9 shows a section along the line 1X-1X of Fig. 6.
  • the floor sweeper 10 shown in the drawing consists of a housing 11.
  • the housing 11 is used externally for receiving a handle bracket 12, on the turn of which a handle-like handle 13 for the reciprocating movement of the floor sweeper over the attached to the cleaning floor. is.
  • 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, these are assigned pinions (not shown in detail) at the ends of the axis 15, which are in operative connection with the drive wheels 16.
  • the drive wheels 16 are mounted in pairs in the housing 11.
  • roller brush 14 Since the roller brush 14 only works up to a certain distance from the side wall areas of the floor sweeper 10 may, of the sidewall regions auxiliary brush 17 are provided for detecting, with the aid also of the brush roller 14 side portion located can be detected outside thesaysbe ⁇ rich, thereby a complete cleaning of the floor corresponds long paragraphs and walls as well as possible in corner areas.
  • an additional ⁇ brush 17 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 their cup-shaped, ie. H. radially outwardly and arranged at the bottom ring of bristles the effective range of the rollers ⁇ brush 14 on the one hand and the sidewall and front wall portion of the housing 11 on the other overlap.
  • the two additional brushes 17 are coupled in a drive-locking manner with drive wheels 18 arranged between them.
  • bearing clips 19 are provided, each of which acts on the ends of the roller brush 14.
  • the bearing bracket 19 is formed by an approximately U-shaped clip made of spring steel and can be positively attached to the two legs of the U-shaped clip on a downward-facing wall part of the housing 11. With these two bearing clasps 19, the roller brush 14 can be easily mounted and removed in the housing 11.
  • the two pinions of the roller brush 14 are each assigned two drive wheels 16.
  • one of the drive runners 16 arranged in pairs is provided with a drive impeller 16 in front of the roller brush 14 and the other drive impeller 16 behind the roller brush 14.
  • the drive wheels 16 have a tread 21 formed by an attached rubber ring 20, which tread 21 presses against the pinion of the roller brush 14, so that the drive wheels 16 are drivingly coupled to the pinion of the roller brush.
  • the roller brush 14 thus rotates.
  • the roller brush rotates at a higher speed. Since the drive wheels 16 are rotated with different directions of rotation when the floor sweeper is moved back and forth as intended, the roller breasts 14 are also rotated with different directions of rotation.
  • the roller brush 14 is assigned two dirt collecting spaces 22 and 23. Seen from the operator, is the
  • Dirt collecting space 22 is arranged behind the roller brush 15 and the dirt collecting space 23 is arranged in front of the roller brush 14.
  • the dirt is swept from the floor to be cleaned in each case into the dirt collecting areas 22 and 23 located in the direction of movement.
  • the two dirt collecting spaces 22, 23 are formed by dirt collecting containers 24, 25, which are closed on all sides except for a dirt inlet opening facing the roller brush 14.
  • the two dirt collecting containers 24 and 25 are connected to one another to form a unit.
  • the two dirt collecting containers 24 and 25 can thus be removed as one part from the housing 11 of the floor sweeper.
  • the emptying of the dirt collecting spaces 22, 23 is thus very simple, since only a part of the housing 11 of the floor sweeper 11 has to be removed for emptying.
  • the two interconnected dirt collecting containers 24 and 25 have a common upper wall 26, the outside of which simultaneously forms the upper side 27 of the two dirt collecting containers 24, 25.
  • the upper side 27 of the two dirt collecting containers 24, 25 also forms part of the upper side of the floor sweeper 10. This can be seen in particular from FIG. 4.
  • the bottom walls 28, 29 of the two dirt collecting containers 24, 25 are through a
  • PI Opening 30 for the engagement of the roller brush 14 is arranged at a distance from one another. At the edges of the bottom walls 28, 29 facing the roller brush, insertion bevels 31 are provided for throwing in the dirt.
  • a part 35 to be grasped by the operator and to be moved to a limited extent in the lifting direction, which moves a resilient locking device 36 into the release position when moving in the lifting direction.
  • a recess 37 is formed in the common upper side 27 of the two dirt collecting containers 24, 25 connected to one another, in which a swivel lever 35 is arranged which covers the recess 37 except for an engagement opening 38 and forms the part which can be moved in the lifting direction.
  • the pivoting lever 35 forming the part that can be moved in the lifting direction is thus arranged in a trough 37 and does not protrude from the upper side 27.
  • the pivot lever 35 has an approximately U-shaped shape, the apex part 39 of which is plate-shaped and the trough 37 except for an engagement opening
  • the plate-shaped apex part 39 of the pivot lever 35 is to be gripped by the operator through the engagement opening 38 with the fingertips.
  • the two legs 40 of the approximately U-shaped pivot lever 35 pass through the upper wall 26 of the two dirt collecting containers 24, 25 and are pivotally supported with their free ends on the underside of the upper wall 26 about a horizontal axis 41.
  • the two legs 40 of the approximately U-shaped. Swivel levers 35 are formed by webs projecting vertically downwards and the underside of the plate-shaped apex part
  • the two legs 40 of the approximately U-shaped pivot lever 35 are formed at their free ends, on the mutually facing sides, bearing pins 41, which engage in bearing bores formed on the bottom wall 26 of the dirt collecting container 24, 25 and projecting downward.
  • the pivoting lever 35 which can be pivoted to a limited extent, lies in the basic position with a part of the apex part 39 against the upper side 27 of the upper wall 26 of the dirt collecting containers 24, 25.
