Thx Tick, Now that we know what type of spring we need, We are discussing the options of transfering the springs torque to the lever/leg arm. The challenge remains that the pin/bar has to remain fixed on both ends while the transfer assy rotates around it, the left end is easy to fix but the...
The table will be used often and quickly during flights and from what i understand from your suggestion of the tension spring mounted idea, the springs would run along side the table and attach above the table, this could cause interference with the overall operation, as well as limit the area...
What would be the challenges with locating the spring in the hinge part of the table locally. Keeping the support arms, and doing away with the torsion bar contraption below.
Basically a spring hinge loaded to the open position where the table is located. It seems to simplify things but I am...
Ok, which leads into my second question, I have the spring that I figure will work however given the limited space in that area, i am having an issue with the torque transfer mechanism, (in other words how does the torsion spring transfer its work to the linkage arm? I have seen plugs and keys...
I have been researching torsion springs and torsion bars for a small spring loaded folding table (imagine a retractable changing table (10"x15") where the spring works to return the table in the stowed position. The table should hold about 4-6lbs (without retracting) and when these items are...
