  • the Saugrohran gleich Swiss connected to the rocker is vertically movably guided on the rear chassis section and occupies different positions relative to the axis of the rollers during forward and backward movements of the chassis.
  • the rocker and the Saugrohran gleich Swiss go into an extended position, without the risk that the landing gear is lifted from the ground.
  • the forces occurring during the handling of the floor nozzle are introduced via the suction pipe connection piece and the rocker into the front section of the chassis. In a forward movement, this leads to a load on the suction head, which increases the pushing force. In a backward movement of the suction head of the suction head is relieved, which can adversely affect the dust pickup.
  • the force distribution in the handling of the nozzle is still in need of improvement.
  • the invention has for its object to provide a nozzle for vacuum cleaner, which always rests flat on the floor surface in forward and backward movements. Furthermore, a favorable force distribution of the introduced via the Saugrohran gleich Swiss force is aimed at both a forward movement of the floor nozzle as well as a backward movement of the floor nozzle.
  • connection between the hinge axle and the rear chassis section is in an area which starts in the suction direction 20 mm in front of the axis of the rollers and ends 20 mm behind the axis of the rollers.
  • the connection by which the forces are transmitted from a suction pipe connected to the Saugrohran gleich Swiss on the chassis, arranged approximately in a vertical axis laid by the roller axis.
  • the force application point of the connection is mounted vertically movable and assumes at a forward movement of the floor nozzle and a backward movement of the nozzle different positions, which do not coincide with the roller axis. Due to the distance of the force introduction point of the roller axis, a lever arm, which results as a product with the force introduced through the suction pipe torque.
  • the force application points can be determined by the vertical mobility of the compound so that when forward and backward movements of the floor nozzle different torques arise, which have a favorable effect on the suction properties of the nozzle.
  • the connection between the hinge axis and the chassis is designed so that the hinge axis occupies a position below the axis of the rollers during a forward movement of the chassis and a position above the roller axis during a backward movement.
  • the connection between the joint axis of the Saugrohran gleich Swisses and the rear suspension section can be realized in a simple manner constructively characterized in that the hinge axis of the Saugrohran gleich Swisses is guided vertically movable in the guide recesses.
  • the guide recesses are arranged on the rear chassis section and the rear chassis section forming roller carrier and expediently have an upper stop and a lower stop for the hinge axis.
  • the stops are set so that, when the nozzle is in use, the hinge axis bears against the lower stop during forward movement of the chassis and against the upper stop during rearward movement of the chassis.
  • the guide recesses are perpendicular or inclined at an angle of 60 ° maximum to the vertical. In the context of the invention, it is also that they are arcuately curved.
  • the suction pipe connecting the suction pipe with the pipe for guiding the suction air is flexible in order not to hinder the force distribution achieved with the vertically movable force application point and to influence.
  • the air duct and the power transmission are preferably functionally separated.
  • a preferred embodiment of the invention provides that the flexible conduit consists of a corrugated hose or a multipart channel movably composed of segments.
  • the suction head has a sliding sole with one or more suction slots which extend across the width of the suction head.
  • the sliding sole can rest directly on the surface to be cleaned or be supported on front rollers.
  • Preferred is a sole with a sole Suction slot which extends over the entire width of the suction head and rests directly on the floor surface when cleaning textile floor surfaces.
  • the suction head on the bottom side retractable and sealing strips, for example in the form of a bristle ring, in the form of bristle strips or sealing lips.
  • the floor nozzle shown in the figures has a chassis 1, which has a rear chassis section 2 with a roller 3 or two arranged on an axis 4 rollers 3 and a projecting in the suction direction front portion 5 for connecting a suction head 6.
  • the suction head 6 is tiltably mounted about a horizontal axis 7 on the front portion 5 of the chassis.
  • a Saugrohran gleich conspiracy 8 is provided, which is arranged about a horizontal hinge axis 9 pivotally mounted on the chassis 1.
  • the hinge axis 9 of the Saugrohran gleich dealtes 8 is connected by a connection 10, which transmits sliding forces between the Saugrohran gleich institutions 8 and the chassis 1, vertically movably connected to the rear chassis section 2.
  • a flexible conduit 12 is provided, which is formed for example as a corrugated hose or may consist of a segmentally movable composite multi-part channel.
  • connection 10 between the hinge axle 9 and the rear chassis section 2 is in a region which starts in the suction direction 20 mm in front of the axis 4 of the rollers 3 and ends 20 mm behind the axis of the rollers.
