Hinge Screw locks up after opening/closing frame

[Shawn0387]

I have a patient that has a fairly new Prodesign frame that they have brought in a couple times where the temple is locked because the hinge screw tightened up on them. Each time I loosened the screw just a smidge and seemed to help but when I open and close the hinge a couple times it locks up. Any suggestions? Should I spread the barrels a pinch? Anyone else ever come across this type of problem?
We were going to just reorder one as a defect warranty but no more are available.

Thanks all

Have you tried a little oil in the hinges?

Like 3-In-One oil?? Not yet

Works just about every time. You only need a tiny bit just on the hinge. Avoid the lenses and rest of frame. Just a small drop and open and close hinges a few times to work it through. Clean with eyeglass cleaner really well when done to make sure there isn't any oil anywhere else.

Can't hurt to replace the screw as well.

Thanks marvinek
Do you typically spread the barrels a smidge too, or does the oil usually do enough on its own?

Loosen the screw, lubricate, tighten screw it should be fine. I get the hinge warm and melt bees wax into the hinge...no petroleum lubricants around the eyes that way.

You can say that again! (Great suggestion)

i had the same problem with the same brand, and used some essential oil on a q-tip cause it smells good. worked great, so far.

We utilize the 3-in-1 for this as well. This is usually enough, without having to adjust the hinge itself.

I carried a Prodesign model 5640 that would bind slightly on opening, at the end of its travel. The rep said some or all of these had less than optimal hinge design and/or fabrication, and were replaced as defective.

I like PTFE based lubricants (Teflon gels and paste) for optical frame hinges. Also works for optical drives that are hanging- use on the laser head guides and tray rails.

Hope this helps,
