The innovation concerns scissors made of steel, in particular / hairdressing scissors, with a hinge screw provided with a spherical head, which is non-rotatably connected to one half of the scissors.

Such scissors are known. In this case, the spherical head of the joint screw lies in a pan-like shape Recess of the movable scissor half. This storage of the ball head has an effect on the joint screw disadvantageous in the following respects. To ensure proper guidance of the movable scissor half on the To achieve a spherical head of the joint screw, the pillar-like recess must be robbed of the head of the joint screw be precisely adapted in that the head lies fully in the recess, but the frictional contact of the head with the movable Scissor half is limited to a minimum.

Because when the movable half of the scissors has play leading to the head of the joint screw is flawless The scissors cannot move. On the other hand takes place at opening and closing the scissors means greater frictional contact of the head with the movable half of the scissors has an effect this is due to the ease of movement of the scissors, in particular is required for hairdressing scissors, disadvantageously. Greater frictional contact also has premature wear

The solution of the object renewal characterized according to j> by a ring-shaped bearing bodies made of hard Art [material constituting the spherical head of the hinge screw on the inner circumference the socket-like bearing for J and is pressed into a cylindrical recess of the movable scissor half.

The bearing body is manufactured by injection molding and therefore ensures great accuracy with reference on its pan-like training and its dimensions. Furthermore, since the cylindrical recess of the movable Scissor half without difficulty with low tolerance can be generated, the position of the bearing body is in the bearing and to the head of the pivot screw advantageous always the same.

An advantageous development of the scissors according to the invention is that the movable scissor half has a conical Ar.lageflache for the bearing body. It is thereby the insertion of the bearing body into the cylindrical recess of the movable scissor half relieved.

The innovation is explained in more detail below in an exemplary embodiment with reference to the drawing. It shows:

1 shows a view of hairdressing scissors and FIG. 2 shows a section along the line H-II of Figure 1.

The hairdressing scissors consist of the two scissor halves 1,2 made of steel, which are secured by a hinge screw 3 are connected to each other. The head 4 of the hinge screw 3 is spherical on the rear on the circumference designed. The shaft 5 of the joint screw 3 has a square 6. The hinge screw 3 reaches through with the shaft 5 a hole 7 of the scissors half 1 with play and a hole 8 of the scissors half 2. The hole 8 is the square 6 of the hinge screw 3 designed accordingly, so that the hinge screw 3 with the Scissors half 2 is rotatably connected. With a 9 is guided on the threaded end of the hinge screw 3 Screw nut designated. This has a groove Io on the front. for example, a The pocket knife blade is used to turn the nut 9 with it. The nut 9 is with a neck 11 in a circular recess the scissors half 2 stored. The neck 11 has an annular groove 13 in which an annular, from flexible material existing body 14 is mounted,

which rests against the neck 11 and the wall of the recess 12 of the scissors half 2 under pressure.

According to the innovation, the joint screw 3 is with its spherical head 4 in an annular bearing body stored, which consists of hard plastic and is designed like a pan on the inner circumference. The bearing body 1st pressed into a cylindrical recess 16 of the scissors half. A closes to the recess 16 conical contact surface 17 for the bearing body 15.
