VACUUM CLEANER

Abstract: A soft vacuum cleaner, in which the motor is enclosed by the filter bag, being inflated by the inspired air, permitting to avoid the shocks with the surrounding objects.

Description: VACUUM CLEANER The present invention relates to the field of evacuating dust and eliminating it and in particular to a vacum-cleaner as described in the first point of the abstract. A problem which has not been solved in a satifactory way until today with existing models, is the damage caused to furniture and walls by moving the machine. Rubberbands around the body of the vacuum cleaner are only reducing the problem but not eliminating it. When the machine is blocking against an object, the immediate solution is to pull vigorously on the tube thereby throwing it without direction against any object on its way. The invention proposes to remedy this inconvenience through the means described in the abstract point no.1 The fact that the motor and its cover do not collide with the surrounding objets will prolong the life of the machine, the objects and the electrical plug. In particular, the blocking of the movement of the machine in places like doors amd staircases are eliminated and the machine will not fall over. The means to avoid the chocs is a balloon advantageously inflated by the exhaust air produced by the motorand the fan. The vacum-cleaner will take a very simple form, balloon-like , through which the filtering bag that retains the dust serves as a protection against the chocs and allows the machine to slide on the floor. Another alternative is to equip the balloon with straps to allow it to be carried on the back. Drawing no.1 represent a vacuum cleaner for dust elimination with a motor 2 attached to a fan 3 creating a depression in a tube terminating with a free end 1 . The motor 2 and the fan 3 are lodged in a body 5 presenting at one end a circular piece 7 to which the inflatable bag 9 is attached. As generally done an electrical plug 6 will permit the electrical supply to activate the motor when a button 8 is pressed. When the fan 3 rejects the air inspired through the tube 4 into the inflatable bag 9, the latter grows suffiently to take an approximately round shape in such a way so that the protruding parts 1 1 of the envelop 5 will be covered and without danger for the surrounding objects particularly when the hose 4 and its free ending 1 are being moved. The dust and other undesirable substances are accumulating in a filter bag before being filtered a second time through the inflated bag. The tube 4 and its free ending are well known. In particular, additional accessories such as brushes of different dimensions may in already known manner be adapted to the ending 1 . In case the vacuum cleaner is being operated by an inexperienced or young person its rounded soft shape will protect the surrounding furniture and walls from possible damage. It is understood that this invention can take other shapes than those described above, based on the same concept.

Claims: CLAIMS 1 . A vacuum cleaner eliminating dust and other indesirable objects, comprising a motor 2 causing a depression in a tube 4 and terminating with a free ending 1 with the characteristic that means have been conceived to avoid the chocs between the motor and the obstacles encountered when in movement. 2. The vacuum cleaner for dust and other undesirable objects according to claim 1 has the characteristic that the means consist of an inflatable bag 9. 3. The vacuum cleaner for dust and other undesirable objects, has the characteristic that the bag 9 is inflated by the air exhausting from the motor 2.
