  • the parallel bar provided according to the invention serves to mark squares or rectangles or to connect the intersections of polygons, be they regular, irregular or also to mark tendons and the like.
  • a centering and dividing angle is accordingly created; which is an easy-to-use tool in terms of its construction and, above all, its weight, and which can be used on the go, d. H. it can be used and used quickly anywhere.
  • This is particularly advantageous, for example, in the case of workpieces which are themselves not transportable, either because of their weight or because they are firmly connected to other components.
  • a centering and dividing angle consists of two contact legs 1, 2 enclosing a right angle and connected at one end to one another. Between the contact legs 1, 2 at their intersection, a central leg 3 is fastened, one longitudinal edge 4 of which bisects the angle bisector of the one enclosed by the contact legs The entire centering and dividing angle is stiffened by means of a cross bar 6, which is connected to the one contact leg 1 and the middle leg 3.
  • a handle 7 is formed with which the centering and pitch angle can be handled.
  • the handle 7 can be made of plastic, for example, and is fastened, for example, by screws to the outside of the contact leg. As can further be seen from FIG.
  • an angled frame 8 enclosing a right angle and having a frame leg 9 is arranged to be longitudinally displaceable on the middle leg 3.
  • the middle leg 3 has, for example at its two ends, transverse webs 11 which laterally enclose the middle leg with their web ends and are advantageously held in grooves in the middle leg in the form of a dovetail-shaped guide.
  • a grip part 11a is provided with a locking screw 12. hen with which the position of the entire angular frame on the center leg 3 can be fixed in the desired position.
  • the free ends of the frame legs 9, 10 of the angular frame 8 are connected at the ends to one another by an arcuate leg 14, which in the example shown is in the form of a quarter circle.
  • a degree pointer 16 is displaceably arranged on the arcuate leg 14 by means of a guide part 17. With a locking screw 18, the degree pointer can be fixed in any position on the curved leg 14. For easier handling of the guide part on the outside of a handle 19, preferably made of plastic.
  • a stop body 21 is slidably arranged on the frame leg 9 of the angle frame 8 parallel to the center leg 3. This stop body 21 consists of a guide part 22 and a stop section 23 perpendicular to the guide part. The stop section 23 is advantageously detachably fastened to the guide part 22.
  • the guide member 22 is guided on the frame leg 9 in the same longitudinal guide grooves.
  • the stop body 21 can be fixed in any position on the frame leg 9 of the angular frame.
  • the entire angular frame can then be moved in the longitudinal direction together with the stop body on the middle leg 3.
  • the centering and dividing angle according to the invention also has a parallel bar 26.
  • This parallel bar is displaceably arranged at one end by means of a guide part 27 on the contact leg 2.
  • the guide part 27 is guided on the contact leg 2 in a manner known per se by means of T-shaped guide grooves into which projections formed on the guide part 27 engage.
  • the guide part 27 can be fixed on the contact leg 2 by means of a locking screw 28.
  • the contact leg 2, which serves to guide the parallel bar 26 is expediently longer than the contact leg 1.
  • a handle 29 is formed on the guide part , advantageously made of plastic, with which an easier handling of the guide part is achieved.
  • the individual parts of the invention different scales according to the centering and pitch angle.
  • a continuous scale 31 is provided on the middle leg, this scale 31 has a millimeter graduation.
  • the two frame legs 9, 10 have. likewise scales 32, 33, which expediently have a millimeter graduation.
  • the scales 32, 33 are arranged on the frame legs such that the longitudinal edge 4 of the middle leg coincides with the start of the scale 32 and the inner edge 34 of the frame leg 10 coincides with the start of the scale 33.
  • On the parallel bar 26 there is preferably also a scale 35 provided that has a millimeter division.
  • the contact leg 2 also has a scale. If the guide part 27 is shifted on the scale by 10 mm, the guide part 27 covers a distance of 14.14 mm on the contact leg 2, the distance between the middle leg 3 and the parallel bar 26 changing only by 10 mm.
  • the operation of the centering and dividing angle according to the invention shown in FIG. 1 is now as follows: First, the radius of a workpiece 38 to be machined, which is shown in broken lines, is set with the stop body 21 on the scale 33 of the frame leg 9, and by means of the locking screw 24, the stop body 21 is clamped in a vibration-proof manner. The entire angular frame 8 is then moved with its stop section 23 to the workpiece up to the stop of the stop body 21 and also fixed in a vibration-resistant manner with the locking screw 12. The centering and dividing angle according to the invention is thus also fixed to and includes the workpiece 38 to be marked, but it can easily be rotated 360 ° and more around the workpiece.
  • the degree pointer 16 is now aligned tet and points exactly to the center of the workpiece 38, which can be easily torn with it.
  • any angle can be set and torn on the workpiece with a scriber.
  • the edge 34 of the frame leg 10 forms the second center line to the workpiece at an angle of 90 ° to the longitudinal edge 4, the angle set with the degree pointer can be added as often as desired by rotating the entire angle and thus any division and any polygon on the Workpiece to be scribed.
  • the parallel bar 26 is used to mark squares or rectangles or to connect the intersections of polygons, be they regular or irregular or to mark chords, secants and tangents or the like.
  • the used distance between the parallel bar and the middle leg is set on the scale of the system leg 2 with the guide part 27. Then the parallel bar is fixed vibration-proof with the locking screw, and now the desired line on the workpiece can be marked, for example with the help of a scriber.
  • the embodiment shown therein differs from that according to FIG. 1 in that on the one hand the adjustment of the angle frame via the handle part 11a and on the other hand the parallel bar are designed differently.
