Patent ID: 8065966

Claim:
An odd link work surface lift that is adapted to extend from a closed position to an open position, thus elevating a connected work surface and to retract from the open position to the closed position, thus lowering the work surface, comprising: a foundation, the foundation having a front pivot and having a back pivot that is spaced from the front pivot, the foundation further having a stance that is defined as a distance of the spacing of the front and the back pivots; a first link, the first link being an elongated member with opposing first and second ends, the first end being pivotally connected with the front pivot; a second link, the second link being an elongated member with opposing first and second ends, the first end being pivotally connected with the first link second end, the second link further having a link pivot between its first and second ends; a mounting bracket, the mounting bracket being an elongated member with opposing first and second ends, the first end being pivotally connected with the second link second end, the mounting bracket further having a cam surface extending from a cam stop at the second end toward the first end; and a traveler link, the traveler link being an elongated member with opposing first and second ends, the first end being pivotally connected with the back pivot, the traveler link extending from the foundation to the mounting bracket cam surface, the traveler link further including a cam follower at its second end, the cam follower being positioned in abutting engagement with the cam surface and being adapted to travel along the cam surface in abutting engagement, the link pivot being connected with the traveler link between the first and second ends; the mounting bracket further including a bearing length that is defined as a distance between the cam follower and the pivot connection of the mounting bracket first end with the second link second end.
