ABSTRACT:
The mechanism for varying the diameter of a body in accordance with this invention is defined by a mechanism in which the grip area intended for expansion comprises a plurality of compressible O-ring elements supported by a cylindrical body section and spaced apart by spacer elements. A stationary end plate which may be formed by the tip portion of a writing implement, forms an abutment against which an end O-ring will be forced for compression. An axially movable adjustment member is also carried on the cylindrical body for engagement with the opposite end O-ring so that as the adjustment member is moved toward the abutment member the plurality of O-rings therebetween will be compressed so that their cross-sectional shapes will be deformed from circular to elliptical thus enlarging the overall outside diameter of the grip portion.
