I can choose from different materials for the shelf itself, but I cannot find the type of hinge I need. I'm looking for a 90 degree spring stop hinge so that the shelf can be pulled down and secured without legs from its attachment on the wall which is between two windows in my very small kitchen. There are many shelves/tables that pull upwards to become tables, some with legs and some without legs like in the trailers, but they won't work for me since I have a radiator in that space, so, that's why I need a pull-down item. There are ironing boards that are pull-down, but I thought I'd ask through this website before I go that route. Please respond to astratourides@yahoo.com and thank you.
