Table Height Adjust Concept

First, I should say this is only a design. Not a model. I will give a short description on my design. This is design to adjust the height of a table to about 40cm with the help of a motor. Support for the table top (as I named in the assembly) provide some short of equal distribution of load. Because of that if apply a load to the front of the table it can be hoisted with out buckling or bending of other components. Two liner bearings are used to provide smooth hoist and avoid bending of the table top. A screw, two gear wheels & a motor is used to drive the mechanism. A trust bearing is used between the screw & bottom of the table to take loads while it is rotated. And a roller bearing is used to avoid tilting of the screw feather. Motor, screw,bearings all are covered if wants gear wheels also can be covered. two push buttons will adjust the height (red & green-one will hoist & other one will lowers).
