Adjustable height table and base assembly

An adjustable height table base assembly, comprising:

• two or more non-telescoping leg assemblies each including a mobile leg member, a stationary leg member positioned adjacent to the mobile leg member, and a linear motion system positioned in between the mobile leg member and the stationary leg member;
• wherein the mobile leg members and the stationary leg members are each a flat vertical support structure;
• wherein the mobile leg members are configured to be secured to and support a table top;
• wherein each linear motion system includes a first portion secured to the mobile leg member and a second portion secured to the stationary leg member;
• wherein the first portions engage the second portions to permit vertical parallel motion of the mobile leg members in relation to the stationary leg members for extending and retracting the leg assemblies to adjust the height position of the mobile leg members;
• a bridge extending between and interconnecting the two or more leg assemblies;
• a synchronizing system configured to maintain a level orientation of each mobile leg member during adjustment of the height position of the mobile leg members;
• and
• a counterbalance mechanism configured to apply an equalized counterbalance lifting force as a height position of the mobile leg members is adjusted;
• the counterbalance mechanism comprising:
• a torsion spring extending between the two or more leg assemblies;
• and
• an equalizing assembly engaging a first end of the torsion spring;
• wherein the equalizing assembly is configured to twist the torsion spring as with adjustment of the height position;
• wherein the equalizing assembly is configured to translate a variable torque exerted by the torsion spring on the equalizing assembly into the equalized counterbalance lifting force exerted by the equalizing assembly on the linear motion systems.
