I need to fix a wooden board (colored blue in my sketches) to a doorframe (which does not contain a door; colored grey in my sketches). I must not damage the doorframe, and the connection must not be permanent, the board is attached and removed daily.
Usually, I would just use a few screw clamps, but since the board covers the whole doorframe, there is no way to apply pressure from both sides of the doorframe.
Now I imagine something (colored green in my sketches) like a screw clamp where one side is bolted or screwed to the wooden board, so it pulls the board against the doorframe.
However, it would be neat if that screwed-on screw clamp had a hinge, so it can rotate to lie flat against the wooden board when not in use.
Is there something I can use for that, or does anyone have another solution for my problem?
