Definitions

  • the invention relates to a vacuum cleaner with a housing into which a suction nozzle opens for connecting a suction hose and are rotatably mounted on the rollers for moving the vacuum cleaner along a floor surface to be cleaned, and with a housing circumferentially at least partially surrounding bumper, the outside over the housing protrudes.
  • Such a vacuum cleaner is known from the patent DE 196 16 156 Cl. With its help, a floor surface can be cleaned. In this case, the user usually pulls the vacuum cleaner on the suction hose behind him. If the vacuum cleaner hits an obstacle, for example a piece of furniture, the impact against the obstacle is attenuated by the protective strip. However, if the user exerts a tensile load on the vacuum cleaner when hitting the obstacle, this may result in the impact strip sliding along the obstacle while the vacuum cleaner is twisting. As a result, the mobility of the vacuum cleaner is impaired and the risk of damaging the obstacle can not be ruled out.
  • Object of the present invention is to develop a vacuum cleaner of the generic type such that it can be moved easily when hitting an obstacle without the risk of damaging the obstacle exists.
  • This object is achieved according to the invention in a vacuum cleaner of the type mentioned, that the bumper is movably mounted on the housing in the circumferential direction of the housing.
  • the movable mounting of the bumper strip on the housing makes it possible to roll them when hitting an obstacle on the obstacle, so that there is no risk that the obstacle is damaged.
  • a rolling movement is performed only by the bumper, but not by the housing.
  • a rotation of the vacuum cleaner when hitting the obstacle is prevented.
  • the vacuum cleaner pulled behind by the user thus travels along the obstacle and can therefore be moved in a simple manner.
  • the bumper completely surrounds the housing in the circumferential direction.
  • the bumper is arranged only in a front of the housing relative to the tensile load acting on the vacuum cleaner by the user via the suction hose.
  • the protective strip forms a shock ring that is freely rotatable about a rotation axis oriented perpendicular to the bottom surface. Due to the free rotation of the shock ring, the movability of the vacuum cleaner is further improved.
  • the shock ring is preferably designed annular.
  • the impact ring comprises an annular support member on the outside of a bumper made of a rubber-elastic material is held.
  • the supporting part can be made of a rigid material, in particular be made of a rigid plastic material and can give the bumper the required mechanical strength.
  • the use of the rubber-elastic shock strip prevents the same when hitting the vacuum cleaner on an obstacle damage.
  • the shock ring is arranged between a lower housing part and a housing upper part of the vacuum cleaner.
  • the lower housing part preferably has a trough-shaped outer contour and comprises a parallel to the bottom surface aligned bottom wall on which the rollers are rotatably mounted. It is advantageous if the rollers are each rotatably mounted on a pivot member which is held about a pivot axis aligned perpendicular to the bottom surface pivotally mounted on the housing base.
  • the bearing of the shock ring is advantageously carried out with the help of support rollers on which the shock ring is seated.
  • the axes of rotation of the support rollers are preferably aligned radially to the axis of rotation of the shock ring.
  • four support rollers arranged in the circumferential direction at a uniform distance from one another may be used, on which the impact ring is seated with a support surface aligned parallel to the bottom surface.
  • the support rollers are preferably each mounted on a bearing pin which is held on the housing base. It is advantageous if the bearing pins can be latched to the lower housing part, because the assembly of the vacuum cleaner is simplified.
  • the thrust ring rests against a plurality of support rollers distributed in the circumferential direction of the housing.
  • the axes of rotation of the support rollers are preferably aligned parallel to the axis of rotation of the shock ring.
  • four in the circumferential direction of the housing evenly distributed support rollers are used.
  • the impact ring can have, for example, a cylindrical support surface aligned coaxially to the axis of rotation of the impact ring.
  • the support rollers are mounted in an advantageous embodiment in each case on a bearing pin, which is held with a lower end on the lower housing part and with an upper end on the upper housing part.
  • a support roller is arranged between each two adjacent support rollers. This gives the bumper a high mechanical strength.
  • the housing upper part has a base part adjoining the impact ring, to which a main part adjoins the impact ring, wherein the base part protrudes on the outside over the main part.
  • the main part is thus reset relative to the base part and the impact ring. Damage to the main part when hitting the vacuum cleaner on an obstacle is prevented.
  • the vacuum cleaner receives by the outside over the main part protruding base part high stability. If the user pulls the vacuum cleaner on the suction hose behind him, there is no danger that the vacuum cleaner tips. The mobility of the vacuum cleaner is thus improved.
  • the lower housing part and / or the base part are arcuately curved in the transition region to the thrust ring. For example, it can be provided that the base part and the lower housing part are convexly curved in their region adjacent to the impact ring.
  • the base part is designed cylindrically symmetrical and the main part has a circular arc-shaped curved central portion which spans the base part. It has been shown that thereby the mobility of the vacuum cleaner can be further improved while ensuring a high tilting safety.
  • the cylindrically symmetrical base part has an axis of symmetry which extends in the plane which is defined by the arcuate curved center I section.
  • a side section of the housing upper part adjoins laterally.
  • One of the side sections may have a dust compartment lid which can be swung or lifted by the user to insert a dust container into the housing.
  • the other side portion of the upper housing part in an advantageous embodiment, an accessory compartment, which is covered by an accessory compartment cover.
  • various suction nozzles can be deposited, which can be connected to the free end of the suction hose. It can also be provided that on a side portion a filter compartment cover is arranged, which covers a filter receiving compartment and having outlet openings through which the exhaust air of the vacuum cleaner can be discharged.
  • the exhaust air flows through this in the filter receiving compartment an air filter, preferably a HEPA filter.
  • a circular arc-shaped curved handle on which the vacuum cleaner can be raised is held on the upper side portion of the vacuum cleaner.
  • the handle is easily accessible to the user.
  • the central portion may have a high mechanical stability, and a tensile load exerted by the user on the vacuum hose on the vacuum cleaner, is taken with the arrangement of the suction nozzle at the central portion thereof.

  • Figure 2 is a front view of the vacuum cleaner
  • Figure 3 is a schematic plan view of a lower housing part of the vacuum cleaner; and 4 shows a sectional view of the housing lower part along the line 4-4 in FIG. 3.
  • a vacuum cleaner 10 according to the invention is shown schematically with a housing 12 which comprises a housing lower part 14 and a housing upper part 16, between which a freely rotatable impact ring 18 is arranged.
  • the lower housing part 14 is trough-shaped and has a bottom wall 20 on which a plurality of pivoting parts 22 are each mounted pivotably about a pivot axis 23 oriented perpendicular to the bottom wall 20 on the underside.
