Hi all -

I think I’m using the right term…I need something like this:

But larger. I want to use this for a door on a chicken coop, so it will lift up and out of the way when I need to get inside. The door is going to be about 22” high, and I’d like to get as much lift as possible.

Thanks for any ideas.

Looks like you want, what I would call a Bench seat hinge? Lots of places sell them.
Lee Valley for example:

Many are spring driven, and will snap shut. So they are not recommended for chests around kids.

But the door can’t just swing out (it would get in the way when I need to clean)...I want it to move parallel to its original position, but out and up, ending up as close to directly above its original position as possible.

Try Googling “Scissor lift” or “Scissor linkage”. That should give you some ideas.

If you want parallel movement, only source I know is scissor/table lifts for coffee tables. They sell large lifts for raising coffee table into dining table with about double the lift as one you posted.
Best Luck.

I’m trying to visualize why the standard strap hinges on the side
of the door to swing out of the way vs something complicated
that will probably rust out eventually.
second option I would think of is to have the door slide up and out
of a track – and set to the side when you need to open it.
then you would have the whole 22” opening available with no hardware.

or – top hinges where the door would swing up and you hold it in the up position
with some wire and a hook. (or, just a hook).
then when it is down, a small hook on each side will lock it.

as a “Yard Bird Enthusiast” myself, I hope you post some photos of your
coop once you get it all built.

I could use standard side hinges. I’ll have to add something to hold the door open, though, and the doors will be somewhat exposed to damage when open.

how can a chicken coop door be exposed to damage when open ?

Similar to that picture above which is for the chickens to go in and out and could be closed for night time security, I made my coop with a larger door on the back that slid sideways. You could even slide it completely off the channels it was held in if needed.

The other alternative is a mechanism that lets the door pivot out and up from the bottom and then slides back inside the coop and out of the way. They are called pocket door slides. They are a little spendy. Here is one sample: https://www.cabinetparts.com/c/drawer-slides/pocket-door-slides

With a little imagination you could probably fabricate a wood version of your own. I did it once on a TV cabinet door so I could have the door out of the way while watching TV.

now, if you were to hire myself and our fellow member, ShipWright,
we would probably go with the nautical theme of having a Companionway Door
where the opening is smaller at the bottom than at the top and there are 3 or 4
boards that slide down into a track with an overlapping lip to keep the water out.
no mechanical hardware. the individual boards store easily out of the way when
not needed. an assortment of ventilation embellishments can be added.
(but, this is strictly for coops found on Row-Day-Oh Drive in Beverly Hills).

Here’s a pic of the front of the coop. As you can see, I’m reusing a cinderblock structure for 3 walls. The cinderblock was already there when I moved in; I have no idea what it was for originally.

The 4×4 across the front is the height of the floor. I was going to put two doors above this. I guess I can just let them swing down.

On a related subject, what do you guys use to waterproof the edges of plywood?

assuming the plywood will be used for the doors ?
if you can find some MDO (Medium Density Overlay) plywood,
that is the most water resistant plywood available.
but if that is not available, a good exterior grade plywood will work
just fine after proper priming and painting.
sign makers usually force exterior grade latex or acrylic caulk into
the open grain of plywood with the fingers to prevent water penetration.
(but, everyone has their own favorite like PVA glue, epoxy, putty, etc).

and back to the subject of the doors, I would put the hinges on the top edge
so the doors would swing up and be held with a hook while you have it open.
