Description

The invention relates to a side wall head brush unit with a hollow cylindrical side wall brush, on the one end face a head brush or floor brush detachable be is fixable.

According to the state of the art, for polishing metal sinks Technology such sidewall head brush units puts. With "head brushes" is the front part of the Unit and with "sidewall brush" the hollow cylindrical Designated part of the unit. Both brushes are in relation to each other detachably arranged.

Problematic with the known side wall head brushes unit is the central mounting bracket attached to a tool spindle must be coupled. The inside of the brush Orderly steel body is also known as a "brush holder" draws. This brush holder is on a shaft journal spanned.

Because the headbrush usually wears out faster than that Sidewall brush, this can be sepa in the prior art advice to be replaced.

With these brushes, the com complicated assembly and disassembly effort highlighted. So the head brush is placed on the egg together with the side wall brush NEN body, which is connected to the drive spindle is attached and by means of a central hexagon socket screwed together.

To ensure that the side wall brush cannot be twisted Most, the receiving body has at least one groove, in the one arranged in the side wall brush accordingly Bar engages.

To loosen the headbrush during work prevent the slope (left or right) of the fastener against the direction of brush rotation len.  

So the side wall brush even after a long period of use It can be replaced without the need for tools, it is an advantage adheres if the holder body is detachable with the side wall brush is attachable.

For this purpose, the receiving body can have at least one latching body point, which is arranged in an interior of the side wall brush Engages locking body receptacle.

The receiving body can advantageously be a latching body have two axially slightly offset pins that are spring loaded. It is also possible to use the pins to be provided on the face with balls, which are in grooves in the In nenwandung the side wall brush are clickable.

Depending on the strength requirements, the receiving body can be made of Plastic or metal or a plastic-metal combination tion exist.

Further advantages and features of the invention result from the following description of an embodiment as well the only figure that is a perspective, partially ge sectioned exploded view of a sidewall head brush most unit shows.

As can be seen from the figure, a side wall-head brush unit 10 consists of a hollow cylindrical side wall brush 12 , to which an end face of a head brush or floor brush 14 can be detachably attached.

To prevent rotation, the receiving body 16 has two axially arranged grooves 22 . In these grooves 22 corre sponding recesses 24 engage, which are arranged on the inner wall of the tenwandbürste 12 .

So that the cylindrical receiving body 16 can snap into the side wall brush 12, there are two axially mutually slightly offset pins 26 in the receiving body 16 . The pins 26 have balls 28 on the end face, which engage in grooves in the inner wall of the side wall brush 12 .

So that later loosening of the entire side wall head brush unit 10 no loosening of the head brush 14 can occur, the direction of rotation of the polishing is opposite to the unscrewing direction of the head brush 14 .

Depending on the desired strength, the receiving body 16 may consist of plastic or metal or of a plastic-metal combination.

According to the invention, it is therefore possible to replace a used head brush 14 simply by unscrewing the used head brush 14 and by screwing in a new head brush 14 .
