A bad day camping beats a good day at the office
Nobody's going to ask how you BROKE YOUR ARM while pushing in a popup bed??
motorized king bed (you saw the idea here first!)
- Thread starter Katskamper
- Start date
How much? I'd have to know the overall length of the straps, their thickness, etc etc.
A single 2" strap is more than strong enough. But I'd use 2x 2" straps, 1 at each side for stability of movement. The straps for those racheting cargo straps should be fine.
The part you're looking for is a DD shaft coupling. When we've needed to make that sort of coupling, we just machined a round coupler and used set screws on the flat of the shaft. But our application was not the same. It would be plenty strong though. Do they make those gear motors in higher ratios? It's better for it to be slower but not jam, than to be faster and jam easily. Those Schwintek motors are 300:1

bed went in crooked & got stuck.
i was pulling it back out, too hard, lost my grip & gravity slammed me down.
my hand was 2 inches off toward pinky, my thumb was at center of wrist. dislocated for sure.
but the SNAP was my arm bone.
see the hole? he vacuumed out shards. may take a YEAR to close up.
lifetime of
steel plate & 9 screws.
& yes it HURTS when i put any weight/pulling on it.
just now able to pull truck door shut with left hand!
this is why i NEED to motorize my bed.

from motor spindle to ratchet cranker.
need the between the 2 part.
the ratchet is what big rig flatbeds use to secure loads. it will handle the bed deck. 100 lbs.
winch only pulls in one direction so thats why not using . need pull in both directions.

I wish I had something to add that would help you. I admire your determination and imagination in regards to this project.

I do admire your determination. I will have to say, much as I loved our popup and all the mods we'd done to it (& the previous one), when my back got too painful, we moved to a small travel trailer. On the trip we realized I could no longer handle the popup reliably solo, I sat inside and cried while my husband finished setting up. That was the last trip in the popup. We knew my joint issues would never go away, and likely keep developing as years went along.
Do I miss the openness of the popup? Sometimes, sometimes I'm thankful for more solid walls - it's a tradeoff. We added an electric tongue jack last year, because my shoulder is not doing well; my husband says he likes the ease too (we experimented with hand cranking it, just in case, and that's easier than the original one).
We each need to make our own decisions. If you are determined to stick with the popup, go for it. This project seems daunting to me, so if it's in your wheelhouse, good for you.

Heck, I'm so lazy I'm into this more than you know. I considered some long travel electric pistons to move our bunk in and out. I've got a future build in mind, to make the short bunk more solid, which drunkenly included a power bunk plan. I'm sure it won't ever happen. I probably won't tell anyone until it's mint, IF I did anything... just sayin'
Moral to my story: More Power to you Kat!

Any luck talking with RV scrap yards for a lippert system pulled from a small slide out with these same parts? Maybe you start the hunt there? There are a number of yards willing to ship in the USA.

Ouch! Really sorry for your situation. Saturday my wife slipped on the ice (yes we still have ice here, unfortunately) and cracked her wrist in 2 places. Much less of a break than you, but she's in a lot of pain.

most slides are less than 3 foot. rails arent long enough. had a lippert repair tech tell me all the difficultiesin the system.
plus the pices!

th
im on a quest now. !
discovered that sourcing parts is not easy, this isnt an off the shelf project. any links would be appreciated.
but this isnt my first invention that ive created out of odd parts.
(see: https://krazykatsmeow.wordpress.com/2015/12/04/ultimate-shower-rig/ )
in my mind, its so simple.
THANKS! seriously, that makes me feel better about this idea.

chasing down parts.
trucker ratchets fit into a c channel.
this unit can roll 30 ft of strap. overkill
c channels are six foot long, sold in pairs.
i need about 3ft.
wait!
is this the same size channel the bed deck uses?
put the winches into c channel, motor inbetween 2 ratchets so it spins both at same time/speed.
motor needs power.
there is a light inside storage box, & it works on 12v or when on electric. my idea is to tap motor into power at light fixture.
when i find the motor switch wiring bundle, i want to mount toggle next to the current electric outlets outside.
that wiring can run below the c channel thru the wall.
c channel will need holes drilled so i can mount it to front wall.
big bolts!

What if you just made the beds so they could be pulled out super easy. Use some really good roller bearing slides. I have drawers in my tool box with heavy weight and they slide out like butter. If you can make them smooth enough you could just have a little pull rope to open the beds.

the bed is 70 inches. king. these look nice, but NOT BIG ENOUGH.
do they make longer ones.?
how would these fit into or attach to current slde C channel?

assembled in photoshop.
for more accurate visuals.
now can you see what im doing?
if i go this build, will i need to weld a square onto the spindles?
different motor?
still looking.
btw, a gallon of milk is about as much as i can carry with my left hand.

does this motor have what it takes to turn a socket to crank a winch?
translate how this relates into plain english for me ?
i vaguely understand.
