No adjustments possible.
I have had the same problem with one of my Tizio lamps, after seeing my sweet housekeeper lift it off of the table by its cross-members( to clean underneath). It still illuminates properly, but refuses to remain in desired position. These are delicate, but elegant lamps.
ps always pick the lamp up by lifting it up from the bottom cylinder.
as always,
Short answer... no.
Check first if the small weight in the lamp head is missing. These lamps are intended to be naturally stable because they are weighted equally across each point of articulation. If the lamp won't stay put, something has changed in that balance. Fix the weight imbalance. The pivot point isn't the problem.
The pivot points between the arms are actually snap fittings. In theory, you could open these and add something that would create more friction. However, the power to the lamp runs through these points, and any foreign substance would add resistance to that electrical path - not a good solution. These lamps (especially the older ones) already have a pretty compromised electrical path. Don't make it worse.
Such an elegant remark
I have nothing to add here except my appreciation for such a well-crafted, informative and thoughtful "technical" post from poach. This post makes me want to read his or her other comments on things that I would not even otherwise be interested in! Thank you.
