Automatic Latching System

Automatic Latching System by Roach Jan 21, 2013

Description

I'm attempting to make an automatic latching system for the lid of my heated build chamber.

The goal is to have a mechanism that a handle is pushed into which latches, and unlatches when pushed on again.

Yes, I think so. Try to find an old car push-button, and open it; you will find such system.

I'm glad it got you curious.

I get that it needs to be pulled to the left, but is there another spring pushing the arm up (Maybe that's what FMA was getting at), so it doesn't fall down from gravity on the right side of the slot you've drawn?

So, one spring to push to the left, and another to push the cam arm up?

Instructions

It's not pictured, but there would be a rubber band or spring pulling the top of the hook arm to the left.

Please make suggestions or modifications to my design!

I'm kinda stuck here.

Hmm, it looks like it needs "funnels" for the pin to indicate direction of motion. For example, on the left side it would probably work better if the bottom path had a large angled inlet.

I think a picture will be in order. I'll try a quick sketch.

It sure does Austin!

I was attempting more of a cam shape, but that failed.

Your illustration is very clear, but makes me wonder how the pin would travel up the right side, assuming gravity is in effect.
