Table with activatable casters

In the stationary state of the table, the four legs rest on the floor.
Step on the yellow bar (red arrow) to switch the table to the movable state: four caster wheels are in contact with the floor instead of the legs. The green latches will lock the yellow and orange bars in the horizontal position.
Two last scenes of the video show how to return the table to its stationary state by rotating (black arrow) the green latches to unlock the bars.
If the table is long, the bars (yellows and orange) may not be joined together and the state switching of two sides is performed one after another.
