Ironmongery for pop up shelf

[Uriah Heep]

A work colleague has posed this problem and we are all stumped.  He wants to build a hi-fi unit with a hinged lid which will on opening allow or cause the shelf on which the stereo sits to rise up.  I saw something like this a number of years ago with a sea chest which doubled as a drinks cabinet so such a device exists.  The question is where to get one?

its the same piece of kit that opens up some kind of bed settees I think its called a bi-radial hinge or something similar
