spatula

The innovation relates to a spatula for cleaning in particular Baking trays with a spatula that consists of several mutually movable spatula tongues that are attached to a carrier.

A spatula with two spatula tongues arranged at an angle to one another is known, each of which is supported by a clamping plate are covered and at their abutment edge with an angle profile and screws adjustable against a Yierkant are screwed. This well-known spatula faces opposite Plach spatula with a spatula tongue has the advantage that the hand guiding the spatula is no longer like with a spatula Plach filler a bending moment but only a compressive force must muster. However, the known spatula has the disadvantage that when moving back and forth on one area to be cleaned, only the way there is to be used effectively as a work trip, while the way back is essentially only for returning the filler to an initial

position for a new way there served it is also with the

Back movement of the spatula has a certain cleaning effect, but it is already known from the flat spatula that the essential cleaning of strong incrustations in particular the feed movement of the working edge and not when it is back retrieval movement takes place, provided that a significantly increased contact pressure is not applied during the return movement ..

The innovation is based on the task of using a spatula create, when actuated, every way is a work trip without an exhausting enlarged one. Pressure applied must become. The solution to this problem is that the working edges of the spatula tongues form a closed polygon. Under a polygon there is also a polygon with an infinite number of corners, i.e. a circle or another geometric area to understand with curved boundary lines.

According to the innovation, the preferred configuration of the spatula is provided that the spatula sheet. from three spatula tongues consists, which are arranged in the shape of a tetrahedron .. With such a design, the spatula tongues are preferred firmly connected to one another in their tip area, for example by soldering »The tip area of the spatula tongues lie in a recess of the carrier. An attachment of the spatula tongues in the carrier can according to the innovation by means of a holder arranged on the inside of the spatula tongues, with which the spatula tongues are connected to the carrier.

are excited. A particularly simple holder has proven to be Proven screw with a "preferably flexible designed washer, for example made of a plastic can exist, is provided "

To increase the flexibility of a spatula can be used in this an incision may be provided. Such putty tongues provided with incisions are advantageous when the putty knife is used for Cleaning of uneven surfaces should be used, as the sections separated from one another by the incision are a With such a design, the spatula tongue bends differently and thus the work surface that is not flat to be cleaned can adapt better »

In order to move the spatula in any direction on the to cleaning surface always has approximately the same cleaning effect To achieve this, it has proven to be advantageous if the spatula tongues of the spatula sheet are in the working position of the spatula are inclined at the same angle to the surface to be cleaned.

To avoid a tilting moment and to create a contact pressure, which is roughly the same on all working edges of the spatula, can be the axis of symmetry running vertically to the working plane of the carrier approximately by the centroid of the
