A compound toggle submechanism for use with a compound toggle system to apply a force to an external object comprises a crank bar, a plurality of pull bars, a plurality of linear toggles, a plurality of coupling toggles, a plurality of three-axis toggles, a plurality of bar toggles, and an object connector. The crank bar is rigidly coupled to a drive shaft and rotates when the drive shaft rotates. Each pull bar rotates about the drive shaft. Each linear toggle moves linearly when the drive shaft rotates. Each coupling toggle rotates and moves when the drive shaft rotates. Each three-axis toggle rotates about one of multiple fixed points when the drive shaft rotates. Each bar toggle rotates about an upper opening on the respective three-axis toggle when the drive shaft rotates. The object connector connects to the external object and moves in a vertical direction when the drive shaft rotates.

A compound toggle system for applying a force to an external object comprises a drive motor, a drive shaft, a frame, and a compound toggle mechanism. The drive motor rotates the drive shaft to a first rotational angle and to a second rotational angle. The frame includes four side walls connected to one another to form a quadrilateral shape and a base connected to the side walls. compound toggle mechanism positioned in the frame. The compound toggle mechanism includes first and second compound toggle submechanisms, with each compound toggle submechanism including an object connector connecting to the external object and providing maximum extension to the external object when the drive shaft is at the first rotational angle and providing minimum extension to the external object when the drive shaft is at the second rotational angle.
