Definitions

  • the invention relates to a telescopic Vacuum cleaner suction tube with an outer tube, a one axially extending locking bar carrying inner tube, at least one with the recesses of the Locking bar interacting locking body, the in a recess of one overlapping the locking strips cylindrical part is held, with a the recess comprehensive, longitudinally adjustable hold-down device at least in one position on the locking body acts.
  • Such adjustment devices for telescopic Vacuum cleaner suction pipes are available in a variety of designs well known.
  • the object of the invention is therefore to one completely without the use of tools to create preassembled adjustment device.
  • the locking body in the designated recess insert without leaving the installation position can.
  • This will assemble the adjustment device overall simplified and generally also the Pre-assembly enables as well as the state of the art auxiliary devices used, e.g. tape or the like, unnecessary.
  • the cylindrical part in the area of the recess provided with mutually facing guides, in which the two ends each with a guide pin provided locking body is held.
  • This embodiment is easy to make because of the guides can be injection molded onto the cylindrical part.
  • Such an adjustment device 10 has one guide bushing 12 fastened on an outer tube 11, one on the guide bushing 12 in the longitudinal axis direction slidably arranged actuating sleeve 13 and a with the actuating sleeve 13 movement-coupled ring cap 14 on, ultimately within the guide bush 12 an inner tube 15 is guided.
  • the adjusting device 10 is shown in the locked state, can one can recognize the unlocked state in FIGS. 4 to 6.
  • the guide bushing 12 is shown.
  • the guide bushing 12 has one on the Outer tube 11 attached area 16 and substantially the actuating sleeve 13 opposite Area 17 on.
  • the area 17 of the guide bush 12 is provided with guide ribs 18 in the side and a lower portion of an annular groove 19 to form an annular spring 20 (see FIG. 20). Expanded in the upper area of the guide bush 12 the annular groove 19 in the area of the guide ribs 18 to a range of motion A for the ring spring 20, the function of which will be described in detail below is explained.
  • the guide bush 12 with one arranged transversely to its longitudinal extent Recess 21 for receiving one shown in Fig. 12 Blocking body 22 provided.
  • the recess has 21 a pocket-like guide at both ends 23, which makes it possible for pre-assembly, the locking body provided with end pin 24 22 from above into the recess 21 without that it falls through.
  • actuating sleeve 13 is the actuating sleeve 13 shown. You can see an overlap area 25, which in the assembled state more or less pushes on the area 16 of the guide bush 12, an area 26 for attaching the ring cap 14 serves and an intermediate area 27, the inner tube side two recesses 28 and 29 for has the locking body 22.
  • An outer peripheral surface F of the actuating sleeve 13 ultimately serves as an actuating surface for the handle hand, the actuating surface - as not shown - also an ergonomic one have favorable shape adapted to the hand of the handle can.
  • the ring cap 14 has a fastening area 30 on that provided with locking projections 31 is, which with a sawtooth-shaped internal locking 32 of the area 26 of the actuating sleeve 13 correspond. Beyond that is special 17 that the ring cap 14 on the inner tube side two spaced abutment projections 33 has, the function of which is described below becomes.
  • the ring spring 20 is shown which when installing the adjustment device 10 the outer surface of the guide bush 12 in the Ring groove 19 can be attached.
  • the function of the Ring spring 20 is also described below.
  • the assembly of the adjustment device 10 can now detached from the outer tube 11 and inner tube 15 (complete pre-assembly) or in connection with Outer tube 11 and inner tube 15 happen.
  • the recess 21 is first the guide bush 12 of the locking body 22 is inserted, this due to the pocket-like guides 23rd is held in it. Then the actuating sleeve 13 in the x direction on the guide bush 12 so far be postponed until an abutment shoulder 34 to an opposite shoulder 35 of the guide bush 12 triggers. In this position (see Fig. 21) is that provided for the arrangement of the ring spring 20 Ring groove 19 free, so that the ring spring 20 on the guide bush 12 can be positioned.
  • the ring spring 20 in the annular groove 37 between the actuating sleeve 13 and ring cap 14 ensures that the movement unit from the actuating sleeve 13 and ring cap 14 after actuation back into the Zero position (relaxed position of the ring spring 20) moved back.
  • This zero position of the ring spring 20 corresponds the locking position shown in FIGS. 1 to 3 the adjusting device 10.
  • FIGS. 4 to 6 shown unlocked position of the adjusting device 10.
  • this position is above the recess 21 including that contained therein Blocking body 22 arranged the recess 28, so that when adjusting the inner tube 15 opposite the outer tube 11 of the locking body 22 upwards can dodge.
