I'm trying to make something like this http://www.strapworks.com/Side_Release_Straps_Belts_s/51.htm
As you can see, the straps feeds through the buckle and extends on. If pulled on, the strap will continue to feed through.
With what I'm making, I need it to be able to feed through like that, but when in use, I need it to stop sliding even with pulling force is applied.
What can I use to "lock" the strap in place temporarily and easily "unlock" when adjusting the strap? Are there any lock in place buckles? Anti-slip devices? I have no idea. I was hoping one of you guys might know of something.
I know it makes it difficult, but I can't say exactly what I'm making as I hope to perhaps get a patent.
