Lifting mechanism for pop-up camper

[czerr]

Good morning!

Has anyone built a lifting mechanism, like the one posted below, for their pop-up camper? I really like the way this lifts the roof up before it hinges open. Great way to get around the foot room issue for sleeping up top. I'm sure there are a few critical dimensions and ratios that need to be incorporated into the design of a mechanism like that. Any pointers would be appreciated!

Thanks!

Or even a place to buy something like this would be really helpful!

Thanks again

Yes, off-the-shelf pop-up kits are definitely a huge gap in the market.

Does someone in the west need to do everything first?

Surely in some categories we could go straight to cheap Chinese, not like they don't have the engineering talent.

Check out @miniorf build, he posted a .pdf of drawings showing all critical dimensions for the scissor lift he used in building his pop up top. Page 1 shows the lift mechanism and bottom of page 2 is the file

Awesome! Thanks. Those look pretty straight forward to build. I'll give it a shot.

A 4 bar linkage works well. You can easily work one out using a compass on a sheet of paper. Just assume on of the links is fixed.

I guess that part of my brain is weak.

How does that relate to being able to raise a roof cap straight up?

A 300lb load up there is a complicating factor, but would prefer a human-power assist rather than electric

A 4 bar linkage is just a method of controlling motion between two bodies. The reimo design is just a 4-bar. Combined with a gas strut (think westfalias etc), you can lift a roof without needing a special zero clearance hinge.

Here is a example on the vanagon westfalia. Its not hard to setup with some cardboard mockup.
