- the recess on each of said columns being registrable with a protrusion formed on an upper end of an associated one of said support feet to form a rigid, vertical connection therebetween;
- said pivotable attachment means comprising:

- an elongated slot in at least one plate of each pair of plates and extending longitudinally of the plate;
- a transverse pivot pin disposed on each of said support feet and extending therefrom through a respective one of said slots;
- a notch formed in at least one plate of each pair of plates;
- and
- a stop registrable with said notch when the recess on said support column is registered with the protrusion in said associated support foot;
