WATER VALVE

For cleaning tiled floors and walls in damp rooms, of bathrooms or terraces or other stone-paved floors, so-called squeegees are used. These consist of a profile strip made of foam rubber, solid rubber or cellular rubber, which forms two adjacent wiper blades that are above one Related back, which is fastened in a U-shaped beam is, which carries a handle grommet in the middle.

In the known water slide valve of this type, the carrier consists of Sheet metal or wood, and the attachment of the profile strip takes place by inserted clamping rails, retaining screws or split pins. Also if for these metal parts expensive, rustproof and difficult to process Material is selected, the screw connections penetrating the back of the profile strip form corrosion pockets because of the The water layer to be pushed away from the device often contains aggressive admixtures, such as cleaning agents. The corrosion nests cause premature destruction of the foam rubber profile strip, solid rubber or cellular rubber. The replacement of a used profile

Strip is impossible or extremely difficult for the consumer to

The task of the innovation, on the other hand, is to design a water slide valve of this type in such a way that it has lower manufacturing costs Requires and the profile strip made of foam rubber, solid rubber or Cellular rubber can be replaced more easily and against corrosion damage is protected.

For this purpose, it is proposed that the back of the profile strip Is T-shaped and in a dovetail groove of the retaining bracket is inserted positively, which consists of plastic.

The profile strip can be removed from the side of the bracket for replacement pulled, and a new profile strip can be inserted from one end face of the retaining bracket in this form-fitting u / earth, whereby only moderate frictional forces have to be overcome. at Using the device will create a bending moment between the T-shaped Hitching the profile strip and the dovetail groove of the retaining bracket transferred, v / strengthened by the spreading of the both wiper blades. This bending moment prevents in interaction with the large coefficient of static friction between the foam rubber the pr ofilst tire and the plastic material of the retaining bracket, that the two parts inadvertently detach from each other when using the device. This makes the previously used expensive failure-prone, complicated to handle metal terminal strips and clamping screws are dispensable.

In a further development of the innovation, the bracket with his The handle cover is made in one piece from plastic.

The innovation is illustrated in the attached sample.
