PCT No. PCT/BR96/00003 Sec. 371 Date Sep. 15, 1997 Sec. 102(e) Date Sep. 15, 1997 PCT Filed Jan. 25, 1996 PCT Pub. No. WO96/22889 PCT Pub. Date Aug. 1, 1996The compass according to the invention comprises a compass top and two compass legs (1,2) mounted rotatably in the compass top, the compass top comprising two top-halves (3,4). Provided in each compass-top half is a bearing pivot (19) for respectively bearing a compass leg, as well as a counter-core (20) which, in the assembled state, engages in the bearing pivot of the corresponding compass-top half. A permanent and even radial frictional clamping is thus produced. At the same time, the counter-cores bring about a limitation to the opening of the compass due to corresponding in the compass legs.
