ABSTRACT:
An adjustable friction mounting for lamps which typically includes an elongated fitting body having a through passage. The passage is cylindrical and has an inwardly-extending terminal circular shoulder at one end, and an outwardly-extending threaded circular recess at the other end, the recess being of greater diameter than the through passage. A flexible resilient inner sleeve or bushing is provided within the passage. The sleeve or bushing is split longitudinally and is disposed coaxially within the through passage. The sleeve or bushing is compressible in service, so that its circumferential dimension may be decreased. An externally threaded ring having an inner face at an angle in the range of 40 to 50 degrees at one end, and relative to its axis, is provided. Thus, when the ring is screwed coaxially into the threaded recess, the face contacts the end of the inner sleeve or bushing and distorts the sleeve or bushing inwards, so that its circumferential dimension is decreased, whereby the sleeve or bushing squeezes against a lamp fixture to provide a frictionally-controlled mounting for the lamp. The elongated fitting body is provided with an external longitudinally-extending flange or the like, to mount the fitting body to a surface such as a wall.
