Spring loaded lift up shelf for kitchen

I do not think Bailey lift up shelves are "spring up"but they do have spring loaded hinges that drop into place to hold them in place 

Have a look at cak tanks web site for the hinges that is where I got some extras from, look at page 112 spring flap hinges may be what you are looking for it is what 

We have a new Adria caravan on order from Downtide Caravans in Norfolk, and when we ordered at the NEC, the dealer offered - before we even asked - to add (at a cost of course) such a shelf as a worktop extension - is that the kind of thing you mean? In our case, this was not an Adria accessory but a locally manufactured/fitted extra. I’ve only seen a photo of it so far but looks ok.

you could try to get a local chippie (kitchen fitter maybe?) to sort it. Or try contacting Downtide. I’m sure other retailers offer similar.

Thanks all have now found the spring brackets on ebay will source and sort some kitchen off cuts
