Filter bag mounting socket

The invention relates to a fastening socket for filter bags which are fitted with a fastening socket to a filter basket outside. In the case of hand dusters with an external filter basket, it is necessary that the filter bag fitted in the filter basket is attached to the detachable seat. This is most often done by means of a flexible clamp 10 which extends over a part of the plate of the filter bag. There are a few significant drawbacks to this structure. Thus, this clamp must always be tightened and loosened when inserting and removing the filter bag. This can easily lead to excessive stretching so that the clamp 15 breaks. Furthermore, a good design for inserting the filter bag, e.g. beveling the inlet edge of the clamp, is only difficult to implement, because due to the difficult space conditions, the clamp can mostly only be made straight.

It is now an object of the invention to shape the fastening hair with the filter bag attachments so that the filter bag can be simply attached and detached again.

According to the invention, the object is achieved in that a lever is pivotally mounted on the mounting socket, one fork-shaped end of which simultaneously surrounds the mounting socket from its circumference and the other free end is formed to hold or release the filter bag frame plate. 30 It is further shown that the other free end of the lever bent at an angle is provided with an opening and a resilient tongue arranged in front of it. In order for the lever to always be in a certain position in the unloaded state, a compression spring is arranged between the fork-shaped head and the receiving point of the fastening seat 35.

It is thus a decisive advantage of the invention that the filter bag can be simply and quickly attached to the mounting socket and removed again.

An embodiment of the invention is shown below.

Figure 1 shows a partial side view of a filter basket with partially cut housing parts.

Fig. 2 is a top view of the part of Fig. 1.

Figure 1 shows a fastening socket 1 to which a filter bag is fastened by means of its frame plate 10. A corner-bent lever 2 is used for fastening, which, as can be seen in Fig. 2, surrounds the fastening sleeve 1 with its fork-shaped head 2 from its circumference 4. The angle-bent lever 2 is then mounted on a pivoting shaft 9. a pressure spring-15 under the action of its location 8 located between the receiving point 7 of the fastening seat and the fork-shaped end 3, so that its free end 5 turns to the right in the plane of the drawing. Thus, it would also not be possible, for example, to place the mounting socket in the filter-basket 11 without the filter bag, since the end 5 prevents this. Now that the filter bag is inserted with its frame plates 10, it slides along the free end 5 into the opening 6 in the free end 5 and simultaneously presses the fork-shaped end 3 downwards, so that the lever 2 bent at an angle obtains the position shown in the drawing. Thus, the filter bag and the mounting socket 1 can be placed in the filter basket 11. When the filter bag is to be discarded, only the free end 5 needs to be pushed aside.
