height adjustable table

grabcad

this is my first model on grabcad, I hope you like it :-). I wanted to create a new lifting mechanism, and I came up with this. The mechanism is built by two pairs of parallel rods. The inner rods are connected by a gears and a wormwheel. The connection between the two wormwheels in the table legs is made by a chain. It's also possible to connect the two wormwheels with bevel gears. The model isn't totally finished yet, but when i find the time i'll detail some things
