US Patent 8065966 Odd link work surface lift

An odd link work surface lift has a foundation with spaced front and back pivots, has a first link pivotally connected with the front pivot and extending to a first end, has a second link pivotally connected with the first end and extending to a second end, has a mounting bracket pivotally connected with the second end and extending to a terminal end, and a traveler link pivotally connected with the back pivot and extending to a cam follower. The mounting bracket has a curvilinear cam surface at the terminal end. The cam follower travels along the cam surface in abutting engagement. A length from the second end to the terminal end is materially greater than a length between the spaced front and back pivots.
