I am working on a design for a combination cart / easel, which is designed much like a chest. I would like to figure out how to make the lid of this chest rise up to about the height of a table. I am an artist first, woodworker second, mostly learning things as I go, and probably don't know quite basic things, but at the same time seem to be able to figure out how to make things work.
I have some ideas, but would like to know if there are terms for what I am describing - searching for a riser leads to unrelated results, and this isn't designed like any existing easel.
To give background...
This was designed to carry my art supplies, but also to fold out in various ways to I can just start painting in a minute, instead of taking 5 minutes to fold out the legs of a french easel ( not to mention getting everything else set up ), but it has everything laid out how I need it. This is all very experimental with the intent of seeing if there is a better way.
I have an existing box like top section ( my lid ), where two drawers slide out to allow a tilting drawing board to rise from underneath - using friction hinges, while the art supplies are on each side. I copied this from some chests I have seen where the top opens not up, but instead has drawer slides to let it slide out. I am not going to go into the design details more than that, except it's a working unit which is complicated (there is a picture attached). This is about 6" tall with plans to add another 2-3" to work as a lid, lights, or other things for art supplies.
Now I also designed a simple cart/box, which is about 12" tall, which fits under this box which it uses as a lid. There is a wheel on one side, and I am planning on adding a handle of some sort to help me pull it.
This combines to be 20" in height ( which just fits into my car trunk )
So what I need is a means of getting the lid to rise up to table height, via some sort of legs that come from the cart, which are both stable and sturdy. The goal here is to have it rise up to about 30", give or take, but I don't mind it being a bit low.
I can think of two approaches, the first is telescoping, where the legs are done like what you find on french easels, two pieces with one inside the other, which let me rise the lid as needed. The problem I see is each leg moves separately, and I would have tighten all 4 at once - or hold up the lid while I am tightening them, which is kind of why I don't like the french easel approach. ( This was my original design idea, but it's exactly why I am building this, to get away from this sort of approach, plus making this sort of leg seems complicated )
The second is to rotate the lid up, by having the legs stored at an angle, and having the lid rotate up into the upright position, then have some means of locking it into position - now here once it's up and the first leg is locked, then the others can be tightened. ( I included a simple design sketch for this )
There is a contraption you can get from rockler, which adds a lift to coffee tables, kind of the ideal solution, but far far too heavy.
All of these let the lid rise up in a manner that it's level all the time.
So I am wondering what other methods are there for lifting a lid.
