What i’ve thought about the release of the clamping action so far is that it might be functional to have handles on the end of the swing arm that clamps down. These are used to push up and out against, and counter the clamping force to open the vise. Especially if the ratio of the swing arm sides is around 1:1 this action should be quite easy. More so if you’re not lifting your own weight because of the positioning of the rear ‘legs’ as i suggest above.
This way the clamping action is ‘on’ most of the time (automatic state) and ‘off’ only when it needs to be, when changing orientation of the work piece.
There is another way. I hesitate to even mention it because i like how simple the Giraffe could be. But there could also be included a foot operated lever to lift the bench up and release the clamping force. Maybe a part of the bench, or maybe a separate device. Think of those old manual operated railway platforms with the dual pump up and down action cantilever to make them go. You stand on one side and the other pushes up on the bottom of the Giraffe.
I prefer the first ideas though. But as Rick M. says, i may need to have it in full scale to test that.
