摘要:
The 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.
