Vorwerk & Co. Wuppertal, November 2nd, 1981 Interholding GmbH. Handheld vacuum cleaner

The innovation relates to a hand-held vacuum cleaner, which rather consists of a motor housing, a guide handle attached to it and a filter basket detachably attached to the motor housing, the filter basket containing a filter bag downstream of your blower.
In a known hand-held vacuum cleaner of this type, the filter bag on the motor housing is hooked with one end inside a collar behind projections and the other end is pressed down until a latching button engages in an opening in the collar. When loosening, the locking button is pressed and the filter basket can be removed upwards.

However, this design has some disadvantages.

Due to the circumferential collar on the motor housing, there must always be a certain "fitting work" must be done in order to guide the filter basket exactly into the locking position.

Furthermore, the surrounding collar also creates inner spaces that can fill up with dirt.

The task of the innovation is now to attach the filter basket to the motor housing to design in vacuum cleaners of the aforementioned type so that they are easy to use and difficult "fitting work" for the user is avoided.

According to the innovation, the object is achieved by the features of claim 1. Further advantageous refinements emerge from the subclaims.

The innovation therefore has a decisive advantage for the filter basket so-called "fitting work" is omitted when fitting and removing from the motor housing. The filter basket is simply folded down or through Snapping the folding movement.

t an exemplary embodiment of the innovation is drawn and

A handheld vacuum cleaner with an attached filter basket,

a handheld vacuum cleaner according to Fig. 1 with the filter basket folded down,

Its part cutout in which the two-joint hinge 90 ° is shown pivoted,

a section through the part of FIG. 3

gt a hand-held vacuum cleaner 12, which consists of a motor housing handle 13 and a filter basket 1 consists. Guide filter cages 1 are arranged on the motor housing 2. Must now 1 remove a filled filter bag (not shown) 3 the filter basket 1 must be detached from the motor housing 2, it, as can be seen from Fig. 2, by a pivoting movement it 1 backwards. There is also a hinge between the motor head 2 and the filter 3 arranged. Function and structure of the hinge 3 g. 3 and 4.

basket 1 cannot be pulled off in the closed state in the motor housing 2 to the right and left of the hinge 3

Lugs 10 (only one lug 10 is shown) over when collapsing Slots 9 (only 1 slot 9 is shown) grip so that the hinge 3 is secured against being pulled off the axis 4.

4 shows the internal structure of the hinge 3. The intermediate part 6 has 4 brackets 11 on the side facing the axis. This allows the intermediate part 6 to rotate on the axis 4 and detached from the axis 4 by pulling it off will. The intermediate part 6 is fixedly arranged on the axis 5. Here, however, the intermediate part 6 is against the axis 5 via the spring element 7 supported so that rotation on the axis 5 is only possible against the spring force of the spring element 7. It follows that when unfolding of the filter basket and motor housing 2, the intermediate part 6 is always rotated by 90 ° on the axis 4 first and then the filter basket 1 can be rotated on axis 5 by a further 90 °. Because the pivot point is first on the axis 4, the filter basket 1 is released from the motor housing 2 possible without rubbing any outer edge.
