Patent ID: 8292221

Claim:
An equipment support for securing aircraft interior equipment to an airframe comprising: a base adapted to be attached to the airframe, said base having an upper portion and a lower portion; a lower support link rotationally attached to the upper portion of said base, said lower support link having a fixed end and a free end, said fixed end of said lower support link comprising a first rotating joint defining a first axis of rotation about said base, said first axis of rotation being oriented substantially vertically relative to said airframe, said free end of said lower link having a second rotating joint thereon defining a second axis of rotation parallel to and offset from said first axis of rotation, said lower support link having a longitudinal axis passing through said first and second axes of rotation; a pilot link, said pilot link having a fixed end and a free end, said fixed end of said pilot link comprising a third rotating joint defining a third axis of rotation relative to said base, said third axis of rotation being parallel to and offset from said first axis of rotation, said free end of said pilot link having a fourth rotating joint thereon defining a fourth axis of rotation, said pilot link having a second longitudinal axis passing through said third and fourth axes of rotation; an equipment platform, said equipment platform rotationally attached to said lower support link at said second rotating joint and to said pilot link at said fourth rotating joint to form a four bar linkage for defining a rotational attitude of said equipment platform as said lower support link rotates about said first axis of rotation; a linear track attached to said equipment platform; and an aircraft interior equipment member attached to said linear track.
