I’m designing a carrying case for my GPS. I know, I can buy one for 10 euros in the local shop, and it may come down to that, but that’s not the point.
I have several designs that are being mulled over, but the bit I’m sortof stuck on is how to close the box (may be hinged, may be slidy) in such a way that it stays shut.
My box will have a “belt attachment”, since we like to take it on walks we’ve found on this excellent web site . It is, as you can imagine, pretty important that the thing doesn’t fall open and the GPS fall splat onto terra firma. It needs to be fairly easy and quick to open and shut so a keyed lock isn’t going to work.

Ideally I’d like to make it from wood, but I’m open to other ideas. “Exotic” hardware is unlikely to be available in my region. It obviously needs to be small. The GPS is slim and 5.5” x 3.5”.

Thanks in advance for any ideas.

Magnets my boy, magnets!

Use two small rare earth magnets, one inset into the inside of the lid an the other inset into the body of the box…

Good Luck!

Are rare-earth magnets really strong enough to hold together during a bit of a hike? I have no experience of them.
I can’t, of course, buy them here – but, hey, i’m off traveling to Dresden next week – if I can just find out the German for “rare earth magnet” I’ll be cooked – worth a try – thanks.

If you get the magnets rated at N40 or better they are more than strong enough

No kidding, you can get those dang magnets so strong it’s hard to pull them apart. They WILL work

I was here thinking, “well, rare-earth is obviously the way to go”...
...and then I wondered if it was smart to put a super-duper magnet in such close proximity to a hi-tech electronic device with storage and a touch screen?
Ah ha!
?

This is all very new for me – I know that the proximity of magnets don’t have any effect on vinyl – what it would do to an iPoodle I have no idea.

Thanks for the link Richard – this line – ”Never place neodymium magnets near electronic appliances” I think pretty much puts paid to the idea of magnets for this.

Back to the drawing board

I’m pretty sure the iPad cover has over 27 rare earth magnets in it. Magnets will only effect CRT screens and Hard/Floppy Disk Drives. Standard electronic circuits and LCD displays are relatively immune from magnetic effets.

I’ve used the kj magnetics countersunk magnet washers to conceal a self closing latch before. I bored into the edge of a frameless panel, attached the magnet with a flat head screw then ran through the edgebander. Similar treatment for the door—just be sure of the polarity before enclosing the magnets. (There’s nothing like a door that refuses to close! haha!)

Those magnets are surprisingly strong for thier size.

Put the lid in a dado, on the sides and bottom only, open on the top end. Slide the lid up to open. You won’t need hinges or a clasp.
