Description

School painting and artist brushes usually consist of one The handle can be comfortably held in the hand with a clamp attached to it and a tuft of hair firmly inserted into it, »Es is common, the handle made of wood and the ferrule made of sheet metal to build. In terms of shape, a distinction is made in particular between two types, namely round brushes and flat brushes. With round brushes there has also already been a move towards making both the handle and the ferrule out of plastic. as The material used was polystyrene. Such polystyrene clamps are against the aggressive substances that are in the paint are included, not permanent. This could be remedied by using plastics for the clamp, which withstand the aggressive substances in the paint. It could therefore be considered that the ferrule is made of polyethylene or to manufacture polypropylene. However, this contradicts the fact that it has not yet been possible to glue the tuft of hair in a polyethylene or polypropylene clamp. Help here and In addition, to ensure that the plastic clamp is retrofitted cold formed, especially in the shape of a flat brush

can be brought is the object of the invention. This accordingly consists of a school painting and artist brush with a plastic force, in which the tuft of hair is held at the free end, initially in a clamp that encloses the tuft of hair in the holding area and is firmly inserted in the plastic swing arm Metal insert. The tuft of hair can be firmly anchored to this metal insert by gluing, 30 that after the metal insert is in turn held firmly in the clamp, with the latter itself is practically inextricably linked. Through the Metal insert, the prerequisite is created that the tuft of hair be properly attached in the plastic clamp can. If then the plastic clamp made of a paint-resistant one Material, for example of the type of polypropylene or of the copolymer known under the trade name "Hostaform" exists, then the problem is solved, which was previously insurmountable seemed, namely an aggressive plastic ferrule to create, in which the tuft of hair is held by gluing.

A particularly favorable training in production results when the plastic clamp is designed as a body of revolution with at least one tuft of hair insert opening at the free end is. From such a plastic clamp shaped as a rotating body can easily be a flat brush clamp, for example be obtained by, according to a further feature of the invention, the plastic clamp including the metal insert and the used, mainly glued-in tufts of hair is cold-formed in a corresponding manner. It is particularly cheap if the metal insert is designed in the form of a circular ring or tubular cylinder.

The invention is explained below with reference to the drawing. Show it:

Fig. 3 shows a plastic clamp, which in connection

can be used with the handle of Fig. 2 and in the holding area of the tuft of hair, not shown has an annular metal insert, partially cut,

FIG. K shows the front area of the clamp according to FIG. 3 t enlarged,

With the school paintbrushes and paintbrushes for artists known up to now, it is common to work the tufts of hair into metal clamps 1 and to connect them firmly to a handle 2 made of wood. In principle, this structure has been retained for brushes with a plastic handle. Accordingly, a clamp 1a (FIG. 2) is fixedly attached to the plastic handle 2a via a tenon connection 3. The clamp 1a is designed as a rotating body. In the holding area k of the tuft of hair 5, a metal ring 6 (Fig. 3, k) is firmly inserted in the clamp 1a, which consists for example of polypropylene. Its inner jacket 7 is in alignment with the reveal 8 of the plastic clamp. As a result of this design, the tuft of bristles 5 comes to rest directly on the metallic inner jacket 7 in the holding area h and is held firmly on the metal ring 6 by means of adhesive.

As rotating body shown in Fig. 3 and 4 molded plastic ferrule 1a may together with the metal ring 6 and the glued-in tufts of hair are deformed cold by action of pressure on two opposite sides of the free ferrules end to the flat ferrule, as shown in Fig. 5 _#
