Question how to make a simple 'cord retractor' mechanism

I want to mount a light fixture on the underneath (ie so it shines down into the room) of a garage storage platform. The platform (its like a shelf on cables) can go up and down about 10 feet so that it easy to remove and add stuff. the light fixture has to be "plugged in" all the time. i want some clever way to 'let out' about 8-10 feet of slack in the extension cord as the whole unit lowers and then take up that slack as it goes back up toward ceiling. I would like to avoid "slip rings" ... any ideas? thanks. not sure which is the best forum to ask this Q...

Can you mount the light to the platform with an excess loop of cord that just moves (shortens/extends) as the platform moves.

I cant think of any way your going to get a retractable reel to automatically reel in or out!

well sure but visualize the platform fully extended (ie near the floor) with the cord fully extended... now the platform raises 10 feet but the slack cord will now just hang down into the garage as a 5 foot long 'loop' and get in the way. I want to somehow take up that 10 ft of slack up near the ceiling so it doesnt get in the way.

This forum is ok.

I can't think of any type of retractor that will work either.

In the diagram..... the FP is a fixed pulley at the ceiling. The WP is a weighted pulley that keeps the slack tight. As the platform goes up and down.... the wire is kept taut by the weighted pulley.

You could get hold of an old canister vacuum cleaner and use the cord retractor from it.

You could even have a couple sets to fixed/stationary pulleys to remove the slack!

Add a box to contain the cord on the platform below where the cord attaches to the ceiling above. With a little initial fiddling and twisting, you should get the cord to drop back into the box consistently as the platform moves up. Think spiral twist and maybe a weight or two on the cord to keep it over the box. Or maybe sloped sides.

A retractor of that style has slips rings in it.
The rings are what make the power connection as the reel turns.

I think this is probably too strong on the rewind for what you want.

Also it unwinds and then locks so you need to give it a bit of a pull to rewind it.
