Apparatus and methods of supporting and shielding flexible outer bags (110) of vacuum cleaners are disclosed. In one embodiment, a suport structure (101) includes a backing plate (100) disposed within the flexible outer bag (110), and one support member (102A, 102B) attached to the backing plate (100) and projecting away from the backing plate (100). The backing and support members contact and extend proximate respective portions of the outer bag (110), providing three-dimensional support to the outer bag (110). Alternately, a plurality of airflow apertures (104A-D) may be disposed through the support structure (101). In another embodiment, a shield structure (800) includes a backing member (806) positioned proximate to and extend over at least a portion of a rear panel of an outer bag (805) of a vacuum cleaner. First and second sidewall members (804A, 804B) are attached to and project away from the backing member (806). Alternately, the shield structure (800) may include top and front shielding members.

L'invention concerne un dispositif et des procédés pour supporter et protéger des sacs extérieurs souples (110) d'aspirateurs. Dans un mode de réalisation, une structure de support (101) comprend une plaque de soutien (100), disposée à l'intérieur du sac extérieur souple (110), et un élément de support (102A, 102B) fixé à la plaque de soutien (100), en saillie par rapport à ladite plaque de soutien (100). Les éléments de soutien et de support sont en contact avec des parties respectives du sac extérieur (110) et s'étendent à proximité desdites parties, procurant un support tridimensionnel audit sac extérieur (110). Dans une variante, plusieurs ouvertures de circulation d'air (104A-D) peuvent être pratiquées dans la structure de support (101). Dans un autre mode de réalisation, une structure de protection (800) comprend un élément de soutien (806) positionné à proximité d'au moins une partie d'un panneau arrière d'un sac extérieur (805) d'un aspirateur et s'étendant sur ladite partie. Un premier et un second élément de paroi latérale (804A, 804B) sont fixés à l'élément de soutien (806) et sont en saillie par rapport audit élément. Dans une variante, la structure de protection (800) peut comporter des éléments de protection supérieurs et frontaux.
