Definitions

  • the invention relates to a sweeper with the features of the preamble of claim 1,
  • a floor area for example a parking space or a hall area
  • the sweeping material is transferred by means of the rotatable sweeping roller in the hopper.
  • the sweeping roller has a plurality of bristles, and frequent use of the sweeper on rough ground surfaces can lead to wear of the bristles, so that the position of the sweeping roller must be readjusted to the ground surface to be cleaned.
  • a similarly configured height adjustment device whose position can also be adjusted by means of a set screw, is from the DE 87 17 834 U1 known.
  • the use of screws requires in most cases the use of additional tools to change the broom in position, since the screws usually sit tight and therefore can not be solved by hand easily.
  • a change in position of the sweeping roller usually several revolutions of the screws are required, this leads to a cumbersome handling.
  • Another disadvantage is that the user can only poorly recognize the actual position of the sweeping roller based on the screws, so that an additional display device is required to make the position of the sweeping roller for the user recognizable.
  • a sweeper of the type mentioned in which the height adjustment cooperates with a structurally complex adjustment mechanism, which has a protruding from the housing of the sweeper turntable with recessed grips, is rotatably held on an eccentric, which in turn cooperates with a two-armed lever height adjustment ,
  • the eccentric on the outside on several locking recesses into which a detent of the two-armed lever can engage.
  • the two-armed lever is resiliently biased by a spring in the direction of the locking recesses of the eccentric.
  • To adjust the height of the user must overcome the elastic biasing force to rotate the turntable, with unfavorable leverage, so that the height adjustment of the sweeping roller a considerable amount of force may be required
  • a sweeper is known in which a sweeping roller is rotatably supported on two pivotable support arms. To adjust the height of the sweeping roller it can be lifted by means of a frame which is also mounted pivotably.
  • a sweeper is known with a housing, a hopper and a sweeping roller covered by the housing, which is rotatably mounted on a height adjustment device about a rotation axis.
  • the height adjustment device comprises two support arms in the form of cheeks on which the sweeping roller is rotatably mounted.
  • the height adjustment device is pivotable about a pivot axis aligned parallel to the axis of rotation of the sweeping roller.
  • the adjusting mechanism has a pivotable about the pivot axis Swivel lever, which moves in the course of a pivoting movement along a side part of the housing.
  • Object of the present invention is to develop a generic sweeper such that the position of the sweeping roller can be changed with relatively little effort, the sweeper having a structurally simple structure.
  • a handle is disposed on the protruding from the housing end portion of the pivot arm, which is held between a detent position in which the pivot arm is locked, and a release position in which the pivot arm is pivotable, reciprocally movable on the pivot arm is. If the position of the sweeping roller to be changed, so this can be moved from its locking position to its release position of the handle and then the pivot arm can be pivoted to the desired pivot position and then locked again by means of the handle, preferably locked to 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 structurally particularly simple embodiment of the sweeper can be achieved in that the handle in the longitudinal direction of the pivot arm is displaced back and forth. To release the handle from its rest position, for example, be provided that the handle is pressed by the user in the direction of the pivot axis.
  • a particularly simple handling can be achieved in that the transition of the handle from its detent position to its release position by lifting the handle from the housing. The user must in such an embodiment, the handle only slightly pull outward and then can transfer the pivot arm in a new pivot position.
  • latching elements for example latching nubs or latching depressions
  • latching elements are arranged on the housing and are arranged with corresponding latching elements of the latching elements Handle together.
  • the locking elements, with which the handle is engageable are arranged on the outside of the housing.
  • the handle on its housing-facing underside has locking receptacles, engage in the outside of the housing arranged locking nubs.
  • the handle has a housing surrounding the end region of the pivot arm surrounding sleeve, which is resiliently biased by a spring element in the direction of the locking elements of the housing.
  • the sleeve is held displaceably in the longitudinal direction of the pivot arm and, contrary to the action of the spring element, can move from a detent position in which it bears against the detent elements of the housing into a release position in which it is positioned at a distance from the detent elements arranged on the housing. be transferred.
  • the release position of the handle is predetermined in an advantageous embodiment of the invention by a stop element, which is arranged on the protruding from the housing end of the pivot arm.
  • the stop element can in this case form a counter holder for the user when operating the handle. This is particularly advantageous in light-weight, hand-pushed sweepers that can be moved with little force. It is favorable in this case if the spring element is clamped between the stop and the sleeve.
  • the spring element can be configured as a coil spring surrounding the pivoting arm.
  • the sleeve can be acted upon with a compressive force 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.
  • the sweeper has two wheels and at least one support wheel, wherein the wheels are rotatable about a common axle and wherein the pivot axis of the height adjustment device is aligned coaxially to the wheel axle.
  • the wheels may be coupled via a drive train with the sweeping roller, so that the rotational movement of the wheels is transmitted to the sweeping roller.
  • the orientation of the pivot axis of the height adjustment coaxial with the wheel axle of the wheels has the advantage that during a pivoting movement of the height adjustment of the drive train between the wheels and the sweeping roller does not need to be readjusted
  • the housing engages over the sweeping roller.
  • a particularly simple operation of the sweeper for changing the position of the sweeping roller can be achieved in that the housing in a sweeping roller overlapping region based on the pivot axis is arc-shaped, because this has the advantage that when pivoting the pivot arm of the distance, the Handle to the housing, remains unchanged.
  • FIG. 1 schematically a sweeper 10 is shown with a frame 12 to which a hopper 14 is held.
  • a hopper 14 In the hopper 14 18 debris can be transferred by means of a covered by a housing 16 sweeping roller, such as dirt, leaves and stones.
  • a housing 16 sweeping roller, such as dirt, leaves and stones.
  • From the frame 12 is oriented obliquely to the vertical upward from a push bar 20 which is releasably connectable to the frame 12, and in its rear region on the frame 12, two wheels 22, 24 are mounted, which are rotatable about a common axle 26.

  • the sweeping roller 18 has a plurality of sweeping bristles 28, by means of which a bottom surface 30 to be cleaned can be swept.
  • a bottom surface 30 to be cleaned can be swept.
  • wear of the sweeping bristles 28 is inevitable.
  • the Broom 18 at an in FIG.
  • cross member 44 is centrally from a relative to the pivot axis 36 radially aligned pivot arm 46 which is rigidly connected to the cross member 44 and an elongated passage opening 48 of the housing 16 passes through and projects with a free end portion 50 via the housing 16.
  • the free end portion 50 of the pivot arm 46 is surrounded by a handle 54, which is held in the longitudinal direction of the pivot arm 46 slidably on the free end portion 50 on its free end of the pivot arm 46 releasably connected by means of a connecting screw.
