  • Suction heads for cylinder vacuum cleaners in practice also as Vacuum cleaner nozzles are mass-produced items.
  • the object underlying the invention is a Specify suction head of the structure described at the beginning, the a flexible, sliding sole that adapts to the ground has and has a simple construction. The number of parts to be assembled should be as small as possible his. In addition, there should be the possibility of the suction head with unchanged design of the plastic housing optionally also equipped with a rigid sliding sole.
  • the sliding sole is pivotably mounted both on the connection piece of the suction channel and on the end on the inner surfaces of the plastic housing, that the box-shaped connecting piece contains transverse webs which laterally delimit the suction channel and whose lower edge is designed as an arcuate, rounded bearing surface, and that the sliding sole is supported on the arched, rounded bearing surfaces of the connecting piece and is rotatably connected by snap connections to wall surfaces of the connecting piece parallel to the transverse webs.
  • the plastic housing does not require anything else Mounting hardware.
  • the plastic housing and the sliding sole are one-piece plastic molded parts, all for the movable support of the sliding sole required Have facilities.
  • the bearing journals engage in associated bearing holes in the sliding sole on.
  • the sliding sole is vertical on the bearing cups supported. Forces acting on the sliding sole are over the bearing shells introduced into the plastic housing.
  • the Bearing journals are hardly stressed and can be used accordingly be dimensioned small.
  • On the inner surfaces of the Plastic housing are suitably molded stops that limit the swivel angle of the sliding sole.
  • the attacks can consist of cones, which in a on the circumference of Engage the slot arranged in the sliding sole.
  • the screw domes are according to an advantageous Embodiment of the invention with lateral offset Swivel axis arranged.
  • the on the bristle carrier plate acting compression springs are supported on washers, the are attached to the screw domes.
  • the sliding sole is pivotally connected to the plastic housing and movable towards the screw domes. If the suction head with a sliding sole rigidly attached to the plastic housing be equipped, this is very simple possible that the sliding sole with unchanged Formation of the plastic housing on the screw domes is screwed on.
  • the compression springs are at one Version with rigidly attached sliding sole between the Slide sole and the bristle carrier plate clamped.
  • the plastic housing of the suction head a standard component, which remains unchanged in versions of the suction head with movable and with rigid sliding sole can be used.
  • the suction head is rigid attached sliding soleplate are to be equipped only minor modifications to the sliding sole make. They consist of having the sliding sole additional holes assigned to the screw domes train through the screws into the screw domes can be turned.
  • the assembly of the invention Suction head is very simple because of the plastic housing and the sliding sole by a snap connection get connected.
  • Suction head include a one-piece plastic housing 1, the contains a suction channel 2 and a top opening 3 for a foot switch, a bristle carrier plate 4, which is arranged vertically movable in the housing 1 and through Actuation of a foot switch inserted in the opening 3 5 can be lowered against the action of compression springs 6 is, and one arranged on the underside of the housing Sliding sole 7.
  • the plastic housing 1 has two vertically aligned, dimensionally stable screw domes 8 for guiding the Bristle carrier plate 4 and the compression springs 6. Further is the suction head in a manner known per se with a turn-tilt joint 9 trained and has one to the rear End of the plastic housing 1 connected roller 10 on.
  • a bristle strip 11 and a rubber lip 12 connected by a lifting movement of the bristle carrier plate 4 on the underside of the plastic housing 1 are retractable and extendable.
  • the sliding sole 7 contains one Suction mouth 13, which on a vertically aligned box-shaped Connection piece 14 of the suction channel 2 connects and opens into a floor channel 15 of the sliding sole 7.
  • the Bottom channel 15 extends essentially transversely to Suction direction over the entire length of the sliding sole 7.
  • the sliding sole 7 is both on the connector 14 of the Suction channel 2 as well as the end on the inner surfaces 16 of the Plastic housing 1 pivotally mounted.
  • the Storage of the sliding sole 7 on the connector 14 is in following explained with reference to the figures. 2 takes one that the box-shaped connecting piece 14 transverse webs 17th contains, which laterally limit the suction channel 2 and their Bottom edge as a curved storage surface 18 is trained.
  • the sliding sole 7 is curved on the rounded bearing surfaces 18 of the connector 14 supported (Fig. 4) and rotatable by locking connections on wall surfaces 19 parallel to the transverse webs 17 of the connector 14 connected. To this end contain the wall surfaces 19 of the connector bores 20, into the pins 21 formed on the sliding sole 7 intervene (Fig. 6).
  • the figures also show that the arcuate rounded bearing surfaces 18 a side Have collar 22 for axially guiding the sliding sole 7.
  • Stops 24 integrally formed, the pivoting angle of the sliding sole 7 limit.
  • the compression springs 6 are on annular disks 26 supported, which are attached to the screw domes 8.
  • the sliding sole 7 can with unchanged design of the Plastic housing 1 also screwed to the screw domes 8 and thereby be rigidly connected to the housing 1.
  • the suction head can optionally be used with a movable sliding sole or one rigidly attached to the plastic housing equip the connected sliding sole.
