Abstract

A motion apparatus for decorative purposes has a rotary motion having at least two rotors movement-coupled to one another and each having an axis of rotation. The rotors each have a rotary base element coupled to one another and rotating synchronously at identical angular speed about their axis of rotation. Each rotor has a securing arm extending at a right angle to the axis of rotation and further has a radially outer front end. The securing arms are moveable in a longitudinal direction of the securing arm perpendicular to the axis of rotation, wherein movement of the securing arms in the longitudinal direction is coupled to the rotation of the rotary base elements such that for a complete rotation of the securing arms the front ends of the securing arms describe a spiral path. Neighboring securing arms are displaced by 180.degree. to one another so as to have a collinear position in which the front ends point toward one another and in which the securing arms have been moved in the same direction into a longitudinal end position. A body is secured to the front end of one of the securing arms and transferred in the collinear position to the front end of the other securing arm. A dr…
