The paper treated a cone with a cylindrical helix as a directrix and the vertex on it. Characteristic elements of a surface formed in such way and the basis are identified, and characteristic flat intersections of planes are classified. Also considered is the potential of practical application of such cone in architecture and design.
Key words: cocleoid cones, vertex on directrix, cylindrical helix directrix.

KONUS ČIJA JE VODILJA CILINDRIČNA ZAVOJNICA A VRH NA VODILJI – KOHLEOIDNI KONUS
U radu je razmatran konus koji ima cilindričnu zavojnicu kao vodilju i vrh na njoj. Uočeni su karakteristični elementi tako nastale površi, bazis i klasifikovani karakteristični ravni preseci površi. Takođe razmatraju se i mogućnosti praktične primene takvog konusa u arhitekturi i dizajnu.
Ključne reči: kohleoidni konus, vrh na vodilji, vodilja cilindrična zavojnica
