steel retractable table legs

[fred55]

HI help or steer me in the right direction - 12 oval tables to make for a hotel 6, 8, 10 foot long; having problem sourcing suitable retracting/folding legs. The old example are made from 3/4" ply which I will source and they have 2 or 3 sets of legs - anybody know of suitable folding legs (heavy duty). thanks for any help or replies.

Thanks Mark.B. Have looked at those could use at a push, to save work was looking at some premade steel ones.
