I have specified hardware for this application several times in the past, but when it came up again today I thought it would be a good opportunity to get some feedback from all of you and come up with the best way to handle this type of opening.  It’s a storage closet for a large folding partition to divide a room.  When the folding partition is stored in the closet, both leaves of the door are in the same plane to fill the opening.  When the folding partition is out of storage and dividing the room, it still extends into the closet so the small leaf of the pair folds back against the larger leaf, to leave space for the folding partition.

Here is a partial plan and a detail:

Questions:

a) The hinge in the drawing for the larger leaf does not exist as far as I know.  What type of hanging mechanism would you use for the larger leaf, that can be concealed when the door is closed and allow the door to open 180 degrees?

b) I would typically use a full mortise continuous hinge to hang the small leaf on the larger one.  Would you do something different?

c) How would you hold the large leaf in the closed position when the folding partition is out of the closet?

d) How would you hold the small leaf in position when the folding partition is stored in the closet?

e) Is there anything other hardware you would specify for this opening?

If anyone has access to a folding partition closet and could send me some photos, that would help pull this all together.  Thanks in advance for your help!  It’s so great to be able to offer this resource to the industry!
