Mechanical locking design

[TheoGodfrey]

Hi there,

I've been trying to think up a mechanical design with limited success. Before I divert more time to this I thought I'd see if anyone knows if something like this already exists, or is commonly utilized. I'm basically trying to come up with a lock system whereby it is pushed down to shut, and then requires a further push-down and pull up to unlock it. The caveat is that it needs to be made entirely from injection-moulded plastic i.e. one or two parts of the same material.

I've tried looking at different snaplatch mechanisms but the ideas I come up with seem too complicated and fragile for general use.

Any thoughts?

Those are called push-push locking mechanisms... Google has plenty to show you.

I think I've sorta got part of the solution - I've been looking at compliant mechanisms - they seem to fit the bill of being of a homogeneous material and very few individual parts

Ignore Blackwhite24... just another plagiarizer that will be dealt with soon.
