Definitions

  • the invention relates to a suction hose, in particular for vacuum cleaners, in the form of a corrugated tube from overlapping wound into a helix Plastic profiles with a shaft that are connected to each other in the overlap area are.
  • suction hoses are known in which the plastic profiles essentially Are S-shaped, with the winding into a helix Starting arch of one profile section the end arch of the other profile section, which are arranged more or less radially, overlaps and in this area then a connection of the coils to one another is provided.
  • the elasticity of such a suction hose is due to the deformation of the helix profile.
  • the invention is therefore based on the object of a suction hose at the beginning mentioned type so that it is easy to manufacture lower pressure loss coefficients even at high flow velocities has flowing air.
  • the invention provides that the profiles are shaped and wound that at least from one side a cover web completely or partially covers the inner opening of the shaft.
  • the plastic profile can be designed so that it is a Shaft with a web formed on one side, the free shaft end reaches over this counterpart of the neighboring spiral winding and there with it connected is.
  • the plastic profile should have a cross-section of a shaft, the Height is greater than its width, of which both sides have different lengths webs lying on one level protrude outwards.
  • the shaft end with the short one Web which only for a more extensive welding than the linear system the above construction ensures - spans the long web of the adjacent spiral section, which in turn now more or less the inner opening covering the shaft.
  • the longer web is extended inwards and under partial Cover protrudes into the opening of the shaft. Overlap in this configuration then this inwardly extended web of one shaft with the long outer web of the neighboring wave, so that at a certain distance, which ensures better bendability of the suction hose, complete Coverage of the inner opening of the shaft is achieved and thus the vortex formation is prevented in the wave profile and the pressure losses are reduced.
  • the plastic profiles wound into a helix preferably consist of PP material, the profiles produced by extrusion being welded or are glued together using a PP adhesive. Because with an adhesive connection the adhesive and the base material belong to the same group of substances one speaks of a connection similar to a welded connection, so that a particularly strong permanent and tight connection is guaranteed.
  • the suction hose shown in Fig. 1 is by helical winding a in Essentially S-shaped profile 1 is formed, the shaft portion 2 of the S-shaped Plastic profile the rear S-arch bridge which has just been formed in this case 3 overlaps. In this area, the coils are welded together.
  • the inner openings 5 result in the Waves 4 starting points at which strong vortices can form, which lead to considerable ones Pressure loss at higher suction speeds of the transported air to lead.
  • FIG Geometry is not to scale, so in relation to the thickness of the overlapping profiles the openings 5 are shown too small.
  • the construction according to the invention 2 provided that the plastic profiles 1 from a shaft with a unilateral flat web exist, which are overlapped with each other and in the contact area of the shaft leg 2 on the web 6 by a Weld 7 or an adhesive joint are connected.
  • the end 8 of the Corrugated leg 2 is shortened by the thickness of the web.
  • the plastic profile 1 "not only with a shaft 4 and a longer web 6, but it also points to the other End of the shaft on a narrower web 9, which has a more flat support caused on the web 6 of the adjacent coil when winding, so here a larger connection area can be achieved.
  • Fig. 3 The construction shown in Fig. 3 is useful only by gluing the Wendel producible. Essential for function, flexibility and kink resistance are that the shaft - which in principle also have a semicircular profile could - is higher than wide.
  • the plastic profiles 1 '' 'an additional extension of the longer web 6 after have inside in the form of a web 6a, which, preferably in a very small Distance that engages web 6 of the adjacent coil, so that with this arrangement the inner opening of the shaft 4 is completely covered.
  • the webs 6a and 6, which overlap each other, are of course not connected to each other, since they slide over each other when the suction hose is bent have to.
