Manufacturer of an interior privacy doorknob with push to retract latch mechanism?
My father-in law has a doorknob in his house that is broken and will trap unsuspecting people inside the room when the door is closed (like my wife). He's had several handymen in to look at it. None can replace it with a knob of the IDENTICAL type as he's demanding.
I had the knob apart. The construction appears to be 1970's or later: There is extensive use of plastic inside of the knob and mechanism. The latch bolt has a feature I haven't seen before: The cam on the knob pushes against a plastic plunger on the end of the latch bolt. This engages a plastic pawl into a hole in another plastic piece that then retracts the latch bolt in allowing the door to open.
Does anyone know the name of the company that manufactured door knobs like this? Thanks.

Without a few photos, it's impossible to say which manufacturer it was, but odds are, they've either gone out of business or have changed their design.
I say this because plastic parts wear out quickly, and are inappropriate for door locks, which should be reliable.
If the metal parts are "standard" dimensions, it might be possible to replace the inner mechanism, but it can be time consuming, even for a well-stocked locksmith.
If other locks in the house are from the same manufacturer and of the same age, I'm afraid they might (will) start breaking soon.
Sorry
