ABSTRACT:
A rotatable holder with position memory particularly useful for restoring a memorized orientation for a support rod for an article. The holder has a fixed part and a rotatable part rotatable on the fixed part. First gearing on the rear of the rotary part meshes with second gearing on the front of the fixed part when a securing bolt moves them together, preventing rotation of the rotary part. Lossening of the securing bolt frees the rotary part to rotate. The rotary part includes a rearwardly extending protrusion with its internally gear toothed. A memory ring disposed inside that protrusion and has peripheral gearing which meshes with the gearing in the protrusion, so that the memory ring rotates with the rotary part. The memory ring is biased by a spring rearwardly along the protrusion to disengage the memory ring from the gear toothing when the securing bolt is loosened, which would enable free adjustment of the rotary part with respect to the fixed part. But with the memory ring gearing in engagement with the gearing inside the protrusion, and with the securing bolt permitting disengagement of the first and second gearing, the memory ring rotates with the rotatable part. To restore the rotatable part to its original orientation, the memory ring is rotated and this rotates the rotatable part to its original orientation. A stop on the fixed part determines the extent of rotation of the memory ring.
