This is achieved in that the rotating body directly - without interposition for example a spring - on the locking body acts that this in its position mechanically is locked. The spring located on the rotating body is only there for the rotating body automatically to bring in the locked position and ultimately should when large axial forces occur, acting on the blocking body Radial forces do not absorb any forces.
  • Rotating body as an actuating or latch rocker trained that with sliding block-like axis projections in scenes arranged on the housing is slidably mounted.
  • This embodiment is characterized on the one hand by a safe Locking effect in that the mutual Bolt surfaces of the actuating or bolt rocker and the Locking body with a certain pressure in the locked Press condition against each other.
  • There is also a high one Ease of use because by creating only a low actuation pressure the actuation or Bolt rocker can be brought into the unlocked state can.
  • even a minor Movement of the actuating or latch rocker due to the combined pivoting and sliding movement of the unlocked Condition can be achieved.
  • the locking body can also be pivoted on the cuff arranged, this happening in particular can that the locking body via a swivel arm is firmly attached to the cuff.
  • this has particular advantages in manufacturing and also Assembly of the telescopic vacuum cleaner suction pipe, there the locking body, which is actually only a few millimeters in size thus has a fixed assignment to the cuff.
  • the actuating latch rocker has a rotary bearing.

  • the actuation or Latch rocker 22 has one for finger actuation provided, with a slightly rising Actuating surface 31 provided rocker arm 32 and one Rocker arm 33, which is only a cover function for has the housing 21.
  • a Formed actuation projection 34 the Locking body 18 facing end face 35 as a locking surface is formed while a side surface 36 the Has function of a sliding surface. 4 can be seen that the locking surface 35 in the locked Flat condition on an opposite surface 37 of the locking body 18 bears.
  • Fig. 2 shows the unlocked state in which the sliding surface 36 on a Inclined surface 38 of the locking body 18 abuts. Under other in this drawing you can see that it through an irregular formation of the sliding surface 36 only a punctiform or linear one partial contact of the sliding surface 36 on the Inclined surface 38 comes through which the friction between the Sliding surface 36 and the inclined surface 38 is reduced.
  • the adjustment device 13 is assembled at inserted inner tube 11 in that the first Locking body 18 in the opening 28 of the housing 21 is introduced. Then the actuation or Bolt rocker 22 pressed into the housing 21. Because of a certain excess of the actuation or Bolt rocker 22 in the area of the axis projections 30 opposite an interior width b of the housing 21 must Actuate or latch rocker 22 with a slight bend apart the side walls 24 with a certain Force in the backdrop-like openings 25 be pushed in.
