| 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 |
