Abstract
A vacuum cleaner suction pipe (1) having first, second, and third pipe segments (2, 3, 4), respectively, the pipe segments (2, 3, 4) being telescopically connected to one another, the first pipe segment (2) being located between the second pipe segment (3) and the third pipe segment (4). There is a control device (5), and the pipe segments (2, 3, 4) are mechanically in interaction with one another via the control device (5) so that when the second pipe segment (3) or the third pipe segment (4) is moved manually in an axial direction relative to the first pipe segment (2) the respective other of the second or third pipe segment (3, 4) is moved at the same time by the control device (5).
Claims12
A vacuum cleaner suction pipe, comprising:
- a first pipe segment,
- a second pipe segment, and
- a third pipe segment,
- wherein the pipe segments are telescopically connected to one another with the first pipe segment being located between the second pipe segment and the third pipe segment,
- wherein a control device is provided with a mechanical coupling that is adapted to mechanically interact with the pipe segments in a manner causing manual movement of one of the second and third pipe segments in an axial direction relative to the first pipe segment to produce movement of the other of the second and third pipe segments at the same time,
- wherein the control device comprises at least one control rod,
- wherein said at least one control rod comprises at least two control rods of which a first control rod is connected to an end of the second pipe segment which faces away from the first pipe segment and a second control rod is connected to an end of the third pipe segment which faces away from the first pipe segment, and wherein the first control rod and the second control rod are in interaction with one another via an actuating mechanism attached to the first pipe segment,
- wherein the control rods run within the pipe segments.
