Definitions

  • the invention relates to a floor sweeper, consisting of a housing with a roller brush rotatably mounted therein and driven by impellers, which is arranged between two dirt collecting spaces, the two dirt collecting spaces having dirt collecting containers which can be removed from the top of the housing and having a resilient locking device securing it in its operating position which can be transferred to its release position by hand.
  • the locking devices In order to make it easier to remove the separate dirt collecting container, the locking devices have therefore already been connected to one another with a bracket spanning the dirt collecting container in order to transfer the two locking devices into the release position by pulling up this bracket.
  • this bracket which overlaps the dirt collecting container, however, the surface of the dirt collecting container is impaired and the space requirement is increased.
  • 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.
  • the two dirt collecting containers are connected to one another and have a common upper side, in which a part to be grasped by the operator and to be moved to a limited extent in the lifting direction is provided, which resilient locking device when moving in the lifting direction transferred the release position.
  • a trough can be formed in the common upper side of the two dirt collecting containers connected to one another, in which a swiveling lever is arranged which covers the trough except for an engagement opening and forms the part which is movable in the lifting direction.
  • the part which can be moved in the lifting direction is thus formed by a pivoting lever which is provided in a depression in the top of the dirt collecting container, so that in operation position of the swivel lever does not protrude above the top of the dirt collecting container.
  • the pivot lever can have an approximately U-shaped shape, 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 top 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 pivoting lever up to an engagement opening, so that the operator can reach under the plate-shaped apex part of the pivoting lever with his fingertips and lift it in the lifting direction of the dirt collecting container, whereby this can be lifted at the same time the locking device is transferred to 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. Due to the shaping of the two webs forming the legs and projecting vertically downwards on the underside of the plate-shaped apex part, a strong construction is achieved which can withstand all loads.
  • the two legs of the approximately U-shaped pivot lever can be formed at their free ends, on the sides facing each other, which engage in bearing holes formed from the upper wall of the dirt collecting container and projecting downward wall parts. This makes the swivel lever more reliable Way pivoted on the wall of the dirt collector.
  • the pivoting lever which can be pivoted to a limited extent, can rest in the basic position with part of the apex part against the upper side of the upper wall of the dirt collecting container and in the pivoted-up position with the legs against the lower side of the upper wall of the dirt collecting container.
  • reliably acting end limits are assigned to the swivel 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 ends projecting from the side walls of the dirt collecting container into corresponding ends Recesses of the housing engages and in the central region has a U-shaped arc formed by bends for resilient inward movement of the ends protruding from the side walls of the dirt collecting container.
  • the free ends of the spring wire can thus be pulled inwards, so that the free ends of the spring wire engaging in corresponding recesses in the housing are transferred to their release positions. Since the U-shaped arch provided in the central area 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 which have inclined surfaces and bear 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 Swiveling up the swivel lever, the two legs of the U-shaped arch of the spring wire are compressed so that the locking device is guided into the release position.
  • 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 spring wire from the downward approaches is prevented.
  • 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 angled downward and inward bends on the free ends of the spring wire ensure that the dirt collection container can be easily inserted into the housing of the floor sweeper, since the angled downward and inward bends act as inclined surfaces that strike the edges of the housing recess that when the dirt collecting container is pushed into the housing of the floor sweeper, the ends of the spring wire are pressed inwards.
  • 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 for the reciprocating movement of the floor sweeper: machine attached to the floor to be cleaned 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, they are assigned to pinions (not shown in detail) at the ends of the axis 15, which are in frictional engagement 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 additional brushes 17 are provided for grasping the side wall areas, with the aid of which the side area lying outside the effective area of the roller brush 14 can also be gripped, whereby a complete cleaning of the floor along shoulders and walls as well as in corner areas is also possible.
  • 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, i.e.. H. Bristle ring arranged radially outwards and downwards 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 hand.
  • 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 with the two legs of the U-shaped clip to a downward-facing wall part of the housing 11. With these two bearing clips 19, the roller brush 14 is easy to assemble and disassemble in the housing 11.
  • the two pinions of the roller brush 14 are each assigned two drive wheels 16.
  • one drive wheel 16 is provided in front of the roller brush 14 and the other drive wheel 16 is arranged behind the roller brush 14 of the drive runner 16 arranged in pairs.
  • 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. Since the drive wheels 16 have a larger diameter than the pinions of the roller brush, 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, the dirt collecting chamber 22 is arranged behind the roller brush 15 and the dirt collecting chamber 23 in front of the roller brush 14. When the floor sweeper is pushed back and forth as intended, the dirt is swept from the floor to be cleaned in each case into the dirt collecting space 22 or 23 lying forward 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 structural 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 therefore 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 also forms the upper side 27 of the two dirt collecting containers 24, 25.
  • the top 27 of the two dirt collecting containers 24, 25 also forms part of the top 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 Opening 30 for the engagement of the roller brush 14 spaced apart.
  • lead-in chamfers 31 are provided for throwing in the dirt.
  • the common side walls 33 of the two dirt collecting containers 24, 25 have cutouts 35 in the region of the opening 30 for placement on the roller brush.
  • 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 interconnected dirt collecting containers 24, 25, 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 pivot lever 35 forming the part movable in the lifting direction is thus arranged in a recess 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 covers the trough 37 except for an engagement opening 38.
  • 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 mounted with their free ends on the underside of the upper wall 26 so as to be pivotable about a horizontal axis 41.
  • the two legs 40 of the approximately U-shaped pivot lever 35 are formed by webs projecting vertically downwards and molded onto the underside of the plate-shaped apex part 39.
  • the two legs 40 of the approximately U-shaped pivot lever 35 are formed at their free ends, on the mutually facing sides journal 41, which engage in bearing bores from the upper wall 26 of the dirt collecting container 24, 25 formed, downwardly projecting wall parts 43.
  • 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 container 24, 25. In the swiveled-up position, the legs 40 bear against the underside of the upper wall 26 of the dirt collecting containers 24, 25. As a result, stops for the swiveling limitation of the swiveling lever 35 are created with already existing parts.
  • the two summarized dirt collecting container 24, 25 in the operating position safe, resilient locking device 36 is formed by a spring wire 44 which is arranged on the underside of the upper wall 26 of the dirt collecting container 24, 25, extends parallel to the pivot axis 41 of the pivot lever 35 and with its two ends 45, which protrude from the side walls 33 of the dirt collecting container 24, 25, engage in corresponding recesses 46 in the housing 11.
  • the spring wire 44 has in its central region a U-shaped arc 47 formed by angled portions for resilient inward movement of the ends 45 protruding from the side walls 33 of the dirt collecting containers 23, 25.
  • the apex part 39 of the approximately U-shaped pivoting lever 35 has on its underside two approaches which have inclined surfaces 49 against the mutually facing outer sides of the two legs 48 of the U-shaped arch 47 of the spring wire 44.
  • the clear distance between the inclined surfaces 49 of the two downward facing posts 50 decreases downwards.
  • the two downwardly directed lugs 50 have end stops for the spring wire 44 formed at their free ends by mutually directed extensions 51, so that the spring wire 44 cannot come free from the downwardly directed lugs 50 of the pivoting lever 35.
  • the spring wire 44 forming the resilient locking device 36 has at its two free ends 45 obliquely downward and inward bends 52 which merge into inward bends 53.
  • the bends 52 thus form bevels 54 with which it is possible to press the two combined dirt collecting containers 24, 25 into the housing 11 of the floor sweeper 10, since the bevels 54 transfer the ends 45 of the spring wire 44 into the release position when they are pressed in.
  • actuation of the pivoting lever 35 is therefore not necessary.
