Automatic carabiner for a harpoon line!

[tromic]

Zahar, I just tried it for you. It works with one hand too, even with gloves. I will make a video when it would be finished...

Here are both videos together.

Where is the glove and where is the one hand in the glove?

Where is the glove and where is the one hand in the glove?

The video would be unclear because the gloves would cover the small "carabiner" (only 45 mm). It is tricky to do it with one hand but it is possible. Third i forth finger hold the body of the "carabiner" and you use thumb end the index finger to turn the latch. It would be easyer if the "carabiner" were longer (60 mm) But why to do that when you have two hands?
You said "The carbine should not break or open when passing through the body of a fish or other obstacle pierced by a harpoon!" I agree with this! But what do you think, does your design using rubber and plastic parts fulfill these requirements? I dont think so.. This is more important than using it with one hand.

It is better to see once than to read 100 times! I showed a video of the work with one hand in a glove - You do not! Because I spent a lot of time looking for a solution - You one day! My carabiner is stopped with metal tubes and 3mm pins! The middle part of the carabiner is larger than the diameter of the rubber hose and the hose is not damaged mechanically! The hose can be replaced without disassembling the carabiner! Latex is used as rubber! You will definitely succeed!

I know you spent a lot of time looking for a solution. It is a difficult task to make such a compex design. From your images I see you had different versions with different parts: white plastic, black plastic, gray plastic, yelow rubber, red rubber, stainles steel... What are the dimensimons of your carabiner? I made my just for fun in two days. I tried to make it is as simple as posibble from scrap material a had at home. I acctually dont need it for spearfishing and wont make another.

For convenient use with one hand in a glove, the length of the carabiner is 76 mm. !

Yes, that is enough. That would be comfortable for use with my device too. And what is the thickness? I suppose it is about 15 mm...?
Does anybody else there have similar device, for same porpose? I suppose nobody other has similar device for one hand operation except you..?

Yes! Diameter 15mm! Only I and my Friends have this carbine! I gave the prototype of the carbine to my Friend Master Yuri Gorislavets for mass production! This summer the carbine may appear on sale!

I tried to find something similar on internet but there was nothing. God luck with it!
