Patent ID: 7828717

Claim:
A mechanized dildo comprising: (a) a cam mechanism comprising: (i) a motor-driven shaft; (ii) an axially spaced plurality of drive cams on and rotationally coupled to the shaft; (iii) a plurality of passive cams circumferentially spaced about each of the drive cams, the drive cams each having a plurality of outwardly projecting lobes corresponding to the number of passive cams of the corresponding set of passive cams, wherein the passive cams of each set operate in unison in response to rotation of the shaft; and (iv) a guide structure for guiding the passive cams generally radially relative to the drive cams; (a) a phallic sleeve comprising an elastic material; (b) a support structure supporting the sleeve in generally coaxial relation to the shaft, the sleeve enclosing the passive cams in proximal relation to the sleeve; and (c) a motorized controller for operating the drive shaft, wherein the drive cams in response to rotation of the drive shaft move the passive cams to deflect corresponding local regions of the sleeve outwardly for expanding a girth of the sleeve, further rotation of the shaft permitting relaxation of the local regions of the sleeve, the passive cams moving inwardly, continued rotation of the shaft producing reciprocating simultaneous and in-phase girth expansions and contractions of all expanding portions of the sleeve.
