SUMMARY

The forum discussion centers around designing a reclining binocular chair with a focus on mechanisms for controlled reclining and rotation. Users propose various solutions, including a hand-crank spiral jack for slow height adjustment and the use of a screw jack for smooth reclining motion. Electric motors from car seats are suggested for ease of use, while others recommend using bicycle cranks for hands-free operation. The conversation emphasizes the importance of portability and simplicity in the design, with multiple users sharing ideas and potential components.

PREREQUISITES
  • Understanding of mechanical design principles
  • Familiarity with screw jack mechanisms
  • Basic knowledge of electric motor systems
  • Experience with DIY furniture construction
NEXT STEPS
  • Research screw jack mechanisms for controlled motion
  • Explore electric motor options from automotive seats
  • Investigate bicycle crank systems for mechanical operation
  • Look into portable chair designs and materials for lightweight construction
USEFUL FOR

DIY enthusiasts, furniture designers, and hobbyists interested in mechanical engineering and custom furniture projects.

I just thought of something. If you can find a scrapped recliner/rocker chair (such as a La-Z-Boy) at a scrapyard, you could just replace the lever assembly with a gear drive and reupholster it.

The number one priority of the chair (besides to function) is to be portable. It needs to break down into enough pieces that it can be carried but not so many pieces that it's a pain to set up.

Ah, I forgot about that. Sorry. La-Z-Boys are pretty much riveted together, (at least, the skeletons that I've seen were).
How about a lawn chair? The recliner ratchet mechanism could be decoupled and tied to an automotive electric window crank mechanism or a screwjack.

chair would need electric massage, port for 110V for laptop power supply.

Obviously. I mean...I didn't think that even needed to be said.

has anyone suggested you look at the plans or the actual item called a steadicam. Buzz me back if you need some info or go to wiki.
