20090072528 | WAND FOR AN APPLIANCE - A wand for an appliance includes comprises first and second tubes and a support mechanism, in which the second tube slides telescopically within the first tube along a common axis. The first and second tubes are arranged to be selectively secured to one another in an extended position or to allow movement therebetween and the support mechanism is located between overlapping portions of the tubes. The support mechanism includes tapered portions arranged to provide support between the tubes at separate points along the common axis of the tubes. By supporting adjacent tubes at a plurality of points along the common axis, the tubes are held more firmly with respect to one another. One tapered portion is able to move with respect to the tubes along the common axis, which reduces play between the tubes. The structural strength and quality of the wand are improved. | 03-19-2009 |

20100140917 | Vacuum fitting connection - A vacuum connection to connect a vacuum fitting to a corrugated hose has an air tube which defines an air channel and fits into the corrugated pipe. The connecting has a securing mechanism to secure the air tube to the corrugated hose. The air tube has an outer diameter which corresponds to the inner diameter of the corrugated hose to create an air tight seal. The securing mechanism has radial projections which are radially biased towards the air tube and engage one or more of the corrugations of the corrugated pipe to secure the vacuum fitting to the corrugated pipe. When the corrugated pipe is to be removed from the fitting, the radial projections may be moved against the biasing force to disengage the corrugations and permit removal of the corrugated pipe from the fitting. The opening of the air tube has a chamfered edge to create a smooth transition from the air channel of the air tube to the corrugated pipe thereby decreasing vacuum loss, debris accumulation and excessive noise. | 06-10-2010 |
20100213700 | WET/DRY VAC ACCESSORY SECUREMENT SLEEVE - An attachment assembly for a wet/dry vacuum comprising first and second tubular structures with a third tubular structure spanning a junction between the first and second tubular structures. The third tubular structure may be resilient to conform to both the first and second tubular structures. In a first position, the third tubular structure may span the junction between the first and second tubular structures and, in a second position, the third tubular structure may be rolled back onto itself to engage only one of the first and second tubular structures. The third tubular structure may resist separation of the first tubular structure from the second tubular structure in the first position. The third tubular structure may also seal the junction between the first and second tubular structures. | 08-26-2010 |
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 |
