Movable base with wheels deployable by cyclic driving assembly

A base assembly comprising:

• a load supporting frame comprising one or more recesses and a mounting portion configured to support a load;
• one or more wheels pivotably mounted to the load supporting frame and movable between deployed and undeployed positions extending from said one or more recesses to support and lift the load;
• a cyclic driving assembly mounted to the frame such that actuation of the driving assembly causes the assembly to move in a first direction to define a continuing cyclic motion of the driving assembly;
• and
• a linkage between the cyclic driving assembly and the one or more wheels translating the continuing cyclic motion from the driving assembly to the one or more wheels such that the one or more wheels have a continuing cyclic motion between the deployed and undeployed positions.

A ratcheting assembly comprising:

• a housing;
• a ratcheting gear rotatably mounted within the housing and comprising a plurality of ratchet teeth and an eccentric opening, the eccentric opening including a rotational center of the ratcheting gear;
• a first ratchet pawl mounted to the housing adjacent to the ratcheting gear to allow rotation in a first direction and to hinder rotation in a second direction opposite the first direction;
• a motion translation member mounted within the opening such that rotation of the ratcheting gear causes a movement of the motion translation member via rotation of the eccentric opening;
• and
• a ratcheting actuation member mounted to the housing and comprising a second ratchet pawl mounted to the ratcheting actuation member adjacent to the ratcheting gear such that actuation of the ratcheting actuation member in the first direction can cause a rotation of the ratcheting gear and actuation of the ratcheting actuation member in the second direction opposite the first direction does not cause a rotation of the ratcheting gear.
