are feasible, whereby the marking angle can be adjusted by i an inexpensive and at the same time wear-resistant construction
should distinguish.

The invention provides for the solution of this problem.

a) that the two sides of the marking angle are connected to each other by a quarter-circle arc scaled as a protractor, the circle centre of which lies at the intersection point of the inner edges of the two sides,

b) that on both legs there are pairs of marking edges aligned with each other, directed at 30° or 60° and at 45° j to the longitudinal edges of the legs and

c> that one leg is designed as a finshed leg with an angled edge bar and the other leg is provided with several rows of holes offset from one another for the insertion of a marking tool.

The marking square according to the invention offers the advantage that it can be used not only as a measuring and marking square but also as an angle sizing tool and as a miter template. In addition, the large number of marking holes makes marking parallel lines in particular much easier.

In a further development of the invention, it can also be provided that one of the legs is provided as a circular template with several circular openings of different diameters. The inner diameter of the quarter-circle arc of the angle grinder is expediently larger than the diameter of the largest circular opening, so that the two I

curved edges of the angle ruler can be used as circle or | circular arc templates. &igr;

According to further features of the invention, at least the longer leg and the quarter-circle arc are provided with an embossed or printed scale on both main surfaces, so that the marking angle can be applied both as a stop angle to a workpiece frame and in the supine position to the middle area of a large, flat workpiece support surface.

•The marking angle is preferably made from steel in one piece, but it can also be made from plastic.

The approach according to the invention is described in more detail below with reference to the drawing, in which:

Fig. 1 shows the marking angle in top view and Fig. 2 shows the marking angle in side view.

The marking angle, which is made in one piece from sheet steel, consists of the two legs 1, 2 of different lengths and a quarter-ring arc 3 connecting the two legs, the circle centre Z of which lies at the intersection point of the inner edges of the two legs 1, 2.

The shorter leg 1 is provided with an edge web 4 bent at a right angle on its outer edge. On the longer leg 2, two rows 5, 6 of small marking holes 7 extending over its entire length are provided for inserting a marking tool. The holes 7 of the two rows of holes 5, 6 are each offset to the right.

The shorter leg 1 also has a slot 8 which is inclined by 3° relative to the longitudinal edges of this leg and which is aligned with a slot 9 on the longer leg 2. The shorter leg also has an end edge 10 which runs at 45° and which is aligned with the lower longitudinal edge 11 of an elongated hole 12 in the longer leg 1 (shown in Fig. 1).

The pair of flush slots S, 9 and the pair of flush edges 10, 11 thus form miter templates for angles of 30°, 45° or 60°.

Finally, the shorter leg 1 is provided with two circular openings 13, 14 and can be used as a circle template, whereby the diameters of the openings 13, 14 are, for example, 20 and 25 millimeters respectively, i.e. smaller than the inner diameter of the quarter-circle arc 3. The inner and outer arcs of the protractor can thus be used as additional circle or circular arc templates.

The marking square is provided with a scale on both long edges of the longer leg 2 and on the outer edge of the quarter-circle arc. These scales are also provided on the back of the marking square (not shown) so that it can be used in both turning positions.
