ABSTRACT:
A self-aligning mechanism utilizes a flexible shaft affixed at one end to a means for rotating it. The other end of the rod is configured to engage a complementarily-shaped opening in a coupler provided with a funnel-shaped front surface to guide the flexible shaft into engagement. In one embodiment, the coupler is mounted directly to the shaft of the device to be adjusted. In another embodiment, the coupler is a pulley which drives, by means of a drive belt, a device which is offset in position relative to the flexible shaft. Wire-retaining means are provided to enable the knob and shaft to be easily removed and reinstalled with a minimum of effort and adjustment, even in the presence of misalignment in the X-, Y-, and Z-axis directions.
