Definitions

  • the invention relates to a sweeper with a housing, a hopper and a sweeping roller covered by the housing and connected to a height adjustment device is mounted rotatably about a rotation axis, wherein the height adjustment by means of an adjustment mechanism about a parallel to the axis of rotation aligned pivot axis is pivotable.
  • a floor surface for example a Parking space or a hall area
  • the broom has a variety of bristles, and with frequent use of the sweeper on rough surfaces, the bristles may wear out come, so that the position of the sweeping roller to the surface to be cleaned must be readjusted.
  • EP 0 157 925 B1 discloses a height adjustment device proposed, on which the sweeping roller is rotatably mounted and adjusted by means of two screws in their position with respect to the bottom surface can be.
  • a similarly configured height adjustment device whose position can also be adjusted by means of a set screw is known from DE 87 17 834 U1.
  • the use of set screws requires in In most cases, the use of additional tools to the To be able to change broom in their position, as the screws usually fixed sit and therefore can not be solved by hand easily. In addition to a change in position of the sweeping roller are usually several Turning the screws required, this leads to a cumbersome handling.
  • Another disadvantage is that the user using the set screws the actual position of the sweeping roller only can be poorly recognized, so that an additional display device is necessary to make the position of the broom recognizable to the user do.
  • Object of the present invention is a generic sweeper in such a way that the position of the sweeping roller with relatively little effort can be changed, the sweeper a structurally simple construction.
  • This object is according to the invention in a sweeper of the type mentioned solved in that the adjustment mechanism to a pivot axis comprising pivotable pivot arm which protrudes from the housing and is releasably lockable in different pivot positions.
  • the sweeper it is to change the position of the Sweeping roller relative to the surface to be cleaned only required, the Swivel arm to pivot about the pivot axis and in the desired Locking pivot position, preferably to lock with the housing. This results in very favorable leverage, so that a change in position the broom is associated with a small amount of force.
  • a handle is arranged between a detent position, in which the swivel arm is locked, and a release position, in the the swivel arm is pivotable, movable back and forth on the swivel arm is held. If the position of the sweeping roller to be changed, so can this Handle to be moved from its rest position to its release position and then the swivel arm can be pivoted into the desired pivoting position and then locked again by means of the handle, preferably be locked with the housing.
  • the transition between the detent position and the release position of the handle can be done for example by rotation of the handle.
  • a constructive Particularly simple embodiment of the sweeper can thereby be achieved, that the handle in the longitudinal direction of the pivot arm out and is displaceable ago.
  • To release the handle from its rest position can For example, be provided that the handle from the user in the direction the pivot axis is pressed.
  • a particularly easy handling can be achieved in that the transition of the handle from its rest position in its release position by lifting the handle from the housing he follows. The user must in such an embodiment, the handle just pull something outward and then the swing arm in a transfer new pivot position.
  • the housing locking elements such as locking knobs or Locking depressions, arranged, with the corresponding locking elements of the Handle together. It is advantageous if the locking elements are arranged on the outside of the housing and with the corresponding Locking elements of the handle can be brought into engagement.
  • the handle has an end portion protruding from the housing the sleeve surrounding the pivot arm, which by means of a spring element in Direction of the locking elements of the housing is resiliently biased.
  • the sleeve is slidably held in the longitudinal direction of the pivot arm on this and can, contrary to the action of the spring element from a detent position in the it rests against the locking elements of the housing, in a release position, in they are positioned at a distance from the latching elements arranged on the housing is to be convicted.
  • the release position of the handle is in an advantageous embodiment of the invention predetermined by a stop element, on the off the housing protruding end of the pivot arm is arranged.
  • the Stop element can in this case form a counter-holder for the user when operating the handle. This is especially true for smooth-running, Hand-pushed sweepers of advantage with low power can be moved. It is favorable in this case if the spring element is clamped between the stop and the sleeve.
  • the spring element can be used as a coil spring surrounding the pivoting arm be designed.
  • the coil spring By means of the coil spring, the sleeve with a compressive force be acted upon in the direction of the housing of the sweeper.
  • the sleeve surrounds the coil spring in the circumferential direction.
  • the Sleeve thus forms a mechanical protection for the coil spring.
  • Sweeper has the height adjustment two about the pivot axis pivotable support arms on which the sweeping roller is rotatably mounted and which are rigidly connected to each other via a cross brace, wherein the Swivel arm is fixed to the crossbar.
  • the two support arms and they connecting cross strut in combination with that of the cross strut protruding swivel arm for the sweeping roller a fork-shaped suspension made by the user to change the position of the roller brush relative to the Floor surface can be easily pivoted.
  • the sweeper has two wheels and at least one Support wheel, wherein the wheels rotatable about a common wheel axle are and wherein the pivot axis of the height adjustment coaxial with Wheel axis is aligned.
  • the wheels can be powered by a powertrain coupled to the sweeping roller, so that the rotational movement of the wheels on the Sweeping roller is transferred.
  • the orientation of the pivot axis of the height adjustment coaxial with the wheel axle of the wheels has the advantage that at a pivoting movement of the height adjustment of the drive train must not be readjusted between the wheels and the sweeping roller.
  • the housing engages over the sweeping roller.
  • a particularly simple operation of the sweeper for changing the position of Sweeping roller can be achieved in that the housing in a sweeping roller overlapping area based on the pivot axis circular arc-shaped is because this has the advantage that when pivoting the Swivel arm, the distance that has the handle to the housing, unchanged remains.
  • FIG. 1 schematically shows a sweeping machine 10 with a frame 12, on which a hopper 14 is held.
  • a hopper 14 In the dirt container 14 can by means of a covered by a housing 16 sweeping roller 18 debris be transferred, such as dirt, leaves and stones.
  • a push bar 20 From the frame 12 is inclined to the vertical upwards a push bar 20 from which is detachably connectable to the frame 12, and in its rear Area are on the frame 12 two wheels 22, 24 mounted around a common Wheel axle 26 are rotatable.
  • the wheels 22, 24 are over a known per se and therefore to achieve a better overview in the drawing, not shown drive train with the between the two Impellers 22, 24 arranged sweeping roller 18 in rotary connection such, that a rotational movement of the wheels 22, 24 transmitted to the sweeping roller 18 becomes.
  • the sweeping roller 18 has a plurality of sweeping bristles 28, with their help a floor surface 30 to be cleaned can be swept. Especially at the Cleaning of rough floor surfaces 30 is a wear of sweeping bristles 28th inevitable.
  • the Sweeping roller 18 on a height adjustment device shown schematically in Figure 2 32 rotatably mounted, which on each end face of the cylindrical Sweeping roller 18 has a support arm 34 which is a coaxial with the wheel axle 26th aligned pivot axis 36 is pivotally supported on the frame 12 and at a free end portion of a first lever arm 38, the sweeping roller 18th rotatably supported about a rotation axis 40, while the free end of a second Lever arm 42 of the support arm 34 via a parallel to the pivot axis 36 aligned Cross strut 44 with the other end face of the sweeping roller 18th arranged support arm is rigidly connected.
  • the pivot arm 46 On its free end, the pivot arm 46 carries by means of a connecting screw detachable connected with this transverse standing Stop element 52.
  • the free end portion 50 of the pivot arm 46 is of a handle 54 which in the longitudinal direction of the pivot arm 46th slidably held at the free end portion 50.
  • the handle 54 has a sleeve 56 which defines the free end portion 50 of FIG Swing arm 46 circumferentially surrounds and in the amount of the stop element 52 is integrally connected to a transverse handle portion 58.
  • the Handle 58 is designed trough-shaped and takes the quer Hopkins Stop element 52.
  • the handle 54 is thus a total of T-shaped designed.
