Abstract
An adjustable clutch mechanism for fixing the relative position of two objects rotationally coupled relative to each other. The pressure resisting the change of rotational position submits to adjustment to permit facile movement but yet resists change from the selected position. The mechanism finds particular utility for holding a portable computer terminal's cover containing a display at a desired position relative to the base containing the keys. The clutch mechanism itself includes two sets of annular rings held against each other by a nut and bolt pressing against a spring which in turn presses against one of the rings. Tightening the screw applies greater pressure to the rings and prevents the relative rotation. The first set of the rings moves with the cover while the second set of rings has a fixed rotational orientation relative to the base. A tubular shaft, affixed to the base, passes through the center of the rings engaging tabs of the second set. The shaft keeps the second set from moving relative to the base. Tabs extending outwardly from the first set contacts one of the arms holding the cover to the base; these tabs, and thus the first set of rings, move with the arms and thus the cover.
