20120111362 | FLOOR CLEANING MACHINE - A floor cleaning machine is described having a first drive head and a second drive head which are both pivotally mounted to a deck. The first and second drive heads are connected together with a link rod. The cleaning width of the cleaning machine can be changed by pivoting the first drive head about a pivot point on the deck. The pivoting movement of the first drive head causes a movement of the second drive head, via the link rod, in order to provide a new separation for the drive heads. | 05-10-2012 |
20120090129 | VACUUM CLEANER AND FILTER BAG - A vacuum cleaner having a collection cavity into which air is drawn by a vacuum drive for the collection of air entrained detritus. The cavity has an inlet vent for entry of dirty air, a base portion for collecting detritus and an outlet, enabling the vacuum drive to-draw air into the cavity. The inlet vent comprises a stub pipe which enters the cavity. A filter bag is disposed in the base portion and includes an aperture for the entry of air-entrained detritus. The bag aperture includes a sliding fit over the stub pipe to engage with the inlet vent so the stub pipe empties into the bag. The bag includes a retaining tie which may be clamped to the aperture back along the stub pipe to prevent disengagement of the bag with the vent. | 04-19-2012 |
20110283471 | Squeegee Assembly for a Floor Cleaning Machine - The present application concerns the field of machines for floor treatment, such as cleaning and scrubbing, and in particular relates to the use of a vacuum squeegee assembly for collecting and lifting liquid from a floor surface during treatment. There is provided a squeegee assembly for collecting liquid from a floor surface, the assembly comprising an elongate roof portion provided with depending leading and trailing elongate squeegee blades, the blades and roof portion together defining an elongate liquid collection chamber when horizontally disposed on the floor surface, the chamber being provided with a vacuum vent so that the pressure in the chamber may be reduced so as to permit airflow entrainment and removal of liquid gathered by the squeegee blades in the chamber, characterised in that the chamber roof portion is upwardly inclined towards an end region thereof so that a floor to roof portion chamber height measured at an end region of the chamber is higher than a corresponding chamber height measured at a mid region of the chamber. | 11-24-2011 |
20110265283 | VACUUM CLEANING FILTER BAG - The disclosure relates to the field of vacuum cleaning and in particular the collection of air-entrained debris, in a filter bag. The filter bag is for use in vacuum cleaning apparatus, and comprises fine planar filtration means in the form of a collection bag and coarse planar filtration means both being adapted to be placed in a suction-induced air stream with the coarse filtration means disposed upstream of the fine filtration means, wherein the fine filtration means serves to provide a fine filter for retaining dust particles and wherein the coarse filtration means comprises a relatively coarse filter material having a thickness of at least 4 mm which provides a matrix volume in which dust may be collected. The volume occupied by the coarse filtration means comprises at least 2%, preferably at least 5%, most preferably at least 10% of the maximum internal volume defined by the collection bag. | 11-03-2011 |
20110239399 | Vacuum Cleaner and Filter Bag Insert for a Vacuum Cleaner - The present invention relates to the field of vacuum cleaners and relates in particular to domestic or commercial cleaners which are provided with a bin (or vacuum chamber), rather than a filter bag, to collect air-entrained detritus. According to one aspect of the invention there is provided an insert ( | 10-06-2011 |
