A couple of months ago Fritz Wagoner (hope I got the name right) came up with a neat idea for a canopy latch which locked by the handle going "over center". A couple of people have asked me if I was interested in making a production version. I liked the original idea but I wanted something that was even more positively locked, a sort of belt plus braces. It had to be easy and intuitive to use and capable of being opened from the outside. Here's the plan:
Here's the prototype:
And here's a link to a short video demonstrating the operation:
