■ Suction hose also for vacuum cleaners

t The innovation concerns a suction hose for vacuum cleaners, which is made of an elastic plastic tube and each at the ends of the , Plastic sch! Also arranged fixed connection parts for connection there is a vacuum cleaner and additional nozzles etc.

In vacuum cleaners, suction hoses are used in particular for suction heads used, where vacuuming with a vacuum cleaner alone is only possible with difficulty. This is mostly the "sucking" over Head ", such as on curtains, so-called galleries and on high

hen furniture, such as cupboards and shelves.

The problem arises especially with the latter, for example a connected one Bring the nozzle back into a horizontal position at a height of approx. 2 m in order to ensure a reasonable suction result. The normal ones Suction hoses actually consist of a relatively elastic plastic hose, which, however, is large with the required bending radii Opposing forces or kinking when bending and thus the suction

; 20 obstructed airflow.

<Although there are suction hoses on the market that use a highly flexible plastic hose, these hoses are so high in production costs that in practice the production costs far outweigh the handling advantage gained.

The task of the masonry is now to provide a suction hose for a vacuum cleaner create, which the handling when "overhead work" is essential facilitated without incurring high costs for the user.

According to the innovation, the object is achieved in that between the elastic Plastic hose and the fixed connection parts highly flexible, In all directions movable intermediate pieces are arranged.
