Abstract
A clinometer including a base plate and a compass which is mounted on the base plate and can measure a strike and a dip angle. The compass includes a first case which is rotationally provided on the base plate so as to move a strike scale indicated on the rim of the compass to a certain position and a second case which is provided in the first case, and which is fixed on the base plate so as to fix a dip scale indicated on the rim of the compass at a certain position.
Claims8
A clinometer comprising a base plate and a compass disposed on the base plate to measure strike and dip angles, wherein:
- the compass comprises (a) a first case rotatably disposed on the base plate to move a strike scale displayed on a rim of the compass to a specific position, and (b) a second case disposed within the first case, the second case being fixed to the base plate to previously fix a dip scale displayed on the rim of the compass at a specific position;
- the second case comprises (a) a strike measurement needle rotating a magnetic force to indicate the strike scale, and (b) a dip measurement ball moving by the gravity to indicate the dip scale;
- and
- the second case is filled within a transparent inducing solution that prevents the strike measurement needle from vertically moving to induce horizontal rotation of the strike measurement needle.
