Description

The present invention relates to a fixed filter holder basket disposed at

  the outside of the engine head of a "broom" type vacuum cleaner and housing a

  paper filtration cornet'de Such fixed baskets bear

  filter have long been known in vacuum cleaners

  dust of the "broom" type comprising a so-called

be mounted downstream.

  These baskets consist either of a fixed nacelle whose outer surface is treated and pierced with air outlets, or of a fixed wire which is covered

a breathable fabric.

  So far, when such baskets

  filter should be used with the most different models

  of dust extractors of the type mentioned above, it was

  necessary to make a basket for each model

  individual filter, since the necessary length, and therefore the necessary volume of the filter, are different from one model to another, In addition, a disadvantage lies in the fact that when these baskets are cumbersome embodiments,

  they require a large volume of packaging for their shipment.

  This consideration is also of considerable importance in view of the current situation.

tariffs in force.

  The object of the invention is therefore to

  such filter baskets so as to allow adaptation to different volumes of necessary filters, while considerably reducing the volume

shipping or packing.

  According to the invention this object is achieved by the fact that the filter holder basket consists of respective internal and external parts which can slide one into the other in the direction of traction and which can

  locked against each other.

  In this case, it is extremely advantageous

  minimum space is required for the purposes of

  the most diverse, for example for shipping,

  tipping or even transport, and that the filter-holder basket of the type described can be adapted to a larger volume

when necessary.

  The invention will now be described in more detail by way of non-limiting example with reference to the accompanying drawings in which:

  FIG. 1 is a schematic diagram of a vacuum

  "Broom" type with filter basket

  FIG. 2 is a sectional view of a basket carrying

  filter in the retracted state telescopically; and FIG. 3 is a side elevation with a section

  of a filter basket in the expanded state telescopic

cally.

  Figure 1 shows a schematic diagram of a

  dust collector 1 of the "broom" type, in which a basket

  2 filter holder according to the invention can be used.

  The vacuum cleaner 1 comprises a head 3 of the motor, the basket 2 filter holder which connects to it, and a handle of

guidance 4.

  By observing FIG. 2, the basket 2 comprises an inner part 5 and an outer part 6 that can slide

one in the other.

  For each position, there is provided between the inner part 5 and the outer part 6 a locking or locking mechanism which is shown in Figure 3 on the

  basket 2 filter holder in the expanded state telescopically.

  The outer portion 6 is pierced with orifices 7 in which hooks or projections 8 of the interned part 5 engage. The two parts are thus locked relative to one another. The locking elements can be arranged in different positions. It is also possible,

  in order to obtain an improved blockage, to provide a

  snap or lock me all the way around

from the periphery.

  It goes without saying that many modifications

  can be made to the filter basket described and

  felt, without departing from the scope of the invention.
