      Hello everybody,

      I am needing to get pointed in the right direction with something seemingly simple that I'm trying to create. This is the general idea:

      1. a 2x2 piece of wood.
      2. cut it directly in half, add a hinge to the middle so it can fold neatly in half.

      3. (the question) - when I unfold the legs, so it becomes one straight piece again, I'm looking for some sort of locking catch mechanism, as small and simple as possible, that will lock the leg into its straight position. This might have some sort of simple release - a button, or a tiny latch lever, etc that can be pressed to release the leg so it may be folded in half again.

      I was hoping for a device simple enough that I could easily apply to different styles of wood by way of screwing it in, both sides flush with the top service, or something of that nature. Its possible that there is a name for this type of hinge or catch, I'm just not aware of it yet.

      Thank you in advance for your advice.
      -Chris

      Hello friend, i just thought about something like this or a similar mechanism for that... It's not the best sketch i made it in my cellphone. Hope it can give you ideas.

      1. Use two screws and with a iron wire... clothes hanger

      2. Interference tolerances with a flexible and resilient material it will hold it beautiful. [​IMG]

      Something like this from McMaster-Carr... the mounting isn't quite what you want but similar latches with different mounting are available.

      Why not use flush mounted neodymium magnets and a plate, if you require a holding force of around 40 lbs. there are many variations of this to use. What is the application for this?

      not sure what the function of the table is, but if you need it held really secure look into "latch type toggle clamps".
