Patent ID: 7971898

Claim:
A multiple link, self jacking mobile work cart, comprising: a main body defining an upper portion and a lower portion supported by a plurality of rotating wheels; a movable support leg, the support leg having an upper end pivotally connected to the work cart adjacent to the work cart main body lower portion and a distal free end adapted to support the cart on a support surface, the support leg being movable between a stowed position and a deployed position; a deployable work table pivotally connected to the work cart main body at the upper portion thereof, the table being movable between a stowed position and a deployed position; an actuator arm having a first end pivotally connected to the work cart main body intermediate the support leg and the work table and having a distal free end; a linkage arm having an upper end pivotally connected to the actuator arm at a first distance “a” from the actuator arm first end, and a lower end pivotally connected to the support leg at a second distance “b” from the support leg upper end; and a control arm having a lower end pivotally connected adjacent to the free end of the actuator arm and an upper end pivotally connected to the work table such that a projection of the actuator arm through the work table in the deployed condition is outboard of the connection between the control arm upper end and the work table main body whereby deploying the work table deploys the support leg into contact with the support surface to stabilize the cart.
