Motorized gearbox mechanism

A motorized gearbox mechanism comprising in combination:

• a cam assembly that is rotatable about a central axis and has a plurality of pathways formed in an outer circumferential surface;
• a stator/rotor assembly contained within said cam assembly that induces said cam assembly to rotate about said central axis when energized;
• an annular output gear element coaxially configured about said cam assembly, said output gear element having a first interface surface on an inner circumferential surface;
• and
• a plurality of cam-actuated gear block assemblies spaced about the circumference of said cam assembly, wherein each gear block assembly includes
• a gear block connected to said plurality of pathways and having a second interface surface;
• wherein each gear block is driven through a two-dimensional circuit of movement in response to rotation of said cam assembly about said central axis, said circuit of movement comprising causing said second interface surface of said gear block to engage said first interface surface of said output gear element causing said gear block to move said output gear element a distance prior to disengaging.
