20150014985 | VACUUM CLEANER SUCTION TUBE - A vacuum cleaner suction tube, having an inner tube received in an outer tube, is provided with an actuating mechanism having a grip structure provides a minimized risk of blocking. A clamping element has a form-fit connection with a pair of clamping wedges, so that both of the clamping wedges can be simultaneously moved with one a single movement of a clamping element that is connected to the grip structure so that the clamping element is moved away from the longitudinal axis of the vacuum cleaner suction tube by sliding the grip structure out of the locking position, and both clamping wedges are simultaneously lifted out of engagement with retaining recesses of the inner tube by moving the clamping element away from the longitudinal axis of the vacuum cleaner suction tube, whereby sliding of the inner tube is enabled relative to the outer tube. | 01-15-2015 |

20130175794 | VACUUM CLEANER SUCTION PIPE - A vacuum cleaner suction pipe with at least one inner and at least one outer pipe, and at least one locking device, the locking device being movable by manual actuation, the locking device having a toothed rack, and in the locking position the rack being kept engaged to a toothed strip of the inner pipe, as a result of which the position of the inner pipe is fixed relative to the outer pipe. The locking device is movable into a release position by axial displacement relative to the outer pipe, and in the release position, the rack can be disengaged from the toothed strip by a relative force between the outer pipe and inner pipe, without the effect of a spring force, by the flanks of the teeth of the toothed strip pushing the flanks of the teeth of the rack upward. | 07-11-2013 |

20100289255 | INSERTABLE TUBE SYSTEM FOR A VACUUM CLEANER - An insertable tube system for a vacuum cleaner, with at least one first tube, a second tube and a coupling for detachable connection of the first tube to the second tube, the coupling having a guide element and a lever button, the guide element being located on the outside of the wall of the first tube, the lever button in the guide element being supported to be able to move around a pivot axis, the lever button being movable by the force of at least a first spring element into a catch position, and the lever button having a catch projection on the bottom, the wall of the first tube having an opening for the catch projection of the lever button, and a mechanical connection between the first tube and the second tube being producible by engagement of the catch projection with a catch recess of the second tube. | 11-18-2010 |
20100287726 | TELESCOPING TUBE SYSTEM FOR A VACUUM CLEANER - A telescoping tube system for a vacuum cleaner, with an inner jacket tube, an outer jacket tube, an inner suction tube and a cable, the inner jacket tube having a smaller cross section than the outer jacket tube so that the inner jacket tube and the outer jacket tube form a telescoping jacket channel, the inner suction tube being located inside of the jacket channel, and the cable being guided within the jacket channel and outside of the inner suction tube. In the telescoping tube system, losses of suction force by the intake of secondary air are reduced to a minimum and reliable cable routing is ensured by there being an outer suction tube, the outer suction tube and the inner suction tube forming an essentially closed suction channel within the jacket channel. | 11-18-2010 |
