Old hardware catalogues used to have something called iirc bar-top hinges, for the kind of thing Del-boy fell through. The pivot ½" proud though? that would be wierd.

That was my first thought, but unless I'm missing the obvious, a cranked hinge is only cranked on one side.

I've looked through a million web pages and online catalogues. I know I've seen what I want, which makes it even more frustrating. The alternative is to mount ordinary hinges on blocks of wood, to lift them above the flap surface. I have done that before, and it worked, but is a bit ugly.

When you hang a door with a 'proud pivot' hinge to allow the doors to fold all the way back clearing architraves the arcane name for the hardware is Parliament Hinge. obv they are set into the edges not into the flat surface.

Offset hinge?

searching for "counter flap hinges" seems to give a fair few. (But I ran away the only time I was asked to fit them: tapered rebates beyond me.)

Almost! That included a double offset hinge. A strap double offset hinge would be perfect.

Yes. Almost perfect - a Parliament hinge, but with the ends with the screw holes bent 90 degrees.

Are we talking about an H-Hinge?

Do you mean 'parliament hinges'?

I had to Google that! Thanks, but no.

Parliament hinges would be fine, IF the 'screw' end were bent out at 90 degrees.

This is a flap, 8 inches wide, 24 long, allowing walk in access to a toy train layout. An ordinary flat hinge would be fine BUT the flap will have track over it, butt jointed at each end of the flap. At the hinge end, the pivot needs to be half an inch above 'base' level otherwise the flap will not rise without the ends of track mashing each other.

I think the simple solution will be ordinary strap hinges mounted on blocks of wood, sufficient to provide clearance.

Offset hinge? The problem I see is that there are any number of bespoke hinges on already existing devices but if you look for a replacement they are never standard as you buy them, you really need to find out where the original came from but on old gear that is probably not possible any more.

How about a double ended strap hinge, a vice and a hammer?

It's called a "Bar flap hinge"

Standard bar flap hinge (Del Boy) will not work as the pivot is too close to the flap surface.

That has crossed my mind, but have reservations concerning my ability to get all four bends (two per hinge) in exactly the right place. That, though, would work perfectly.
