Closing a beveled lid

Will1987 · 02-19-2008, 02:54 PM

I'm wondering if anybody knows the best type of fastener to use to close a lid where 2 60 degree angles come together. Ha, can anybody guess what I need this for? I want something that can somehow latch or fasten automatically when it shuts, then be opened by some sort of release button or something. Also I want it to be high strength because people may be lifting the item by the lid. I guess I should get in touch with some specialty fastener company but I wondered if anybody here could steer me in the right direction.
In fact, owing to the angle (60 degrees on the inside, 120 on the outside) that's formed when it closes, I'm having trouble even thinking of how more ordinary fasteners (like little j bolts or hooks or whatever) would work here. Any thoughts?

thanks a lot,
Will

Hey, Will - Once again, looks like you've stumped the group. If you are after completely hidden hardware on this thing then you will be into uncharted territory as far as hinges. Many of the double and triple acting cabinet door hinges MIGHT be made to work with a lot of engineering and proper blocking. Barrel or SOSS hinges might work with the proper blocking as well, I don't think it would be worth the effort though unless you are trying to make a museum piece.

If it was me, it would simply come down to a piano hinge, then the decision to surface mount or only allow for pin exposure. Pin/pivot exposure would need; wide leaf piano hinge, proper blocking and relief at that joint.

As far as latches go, there are many exterior hasp latches that would work, some may need a recess or applied blocks on the exterior to make them work. If you want hidden, same deal as before, there are many keyed and button latches available, you will simply need to engineer the correct interior blocking to "fool" the latch into operating like a typical lid/top.
