Positioner mechanism using linear adjusting lock

A positioning mechanism device to set a position between a first surface and a second surface comprising

• a linear adjusting lock comprised of
• a rod with an outer diameter and anchor hole,
• at least one coil spring with an inner diameter, and a tang at either end,
• an annular, notched sleeve and a release blade, and
• an annular notched bearing,
• wherein one tang of at least one coil spring mates with the notch in the annular, notched sleeve, and wherein the other tang of at least one coil spring mates with the notch in the annular notched bearing;
• wherein the inner diameter of the spring is smaller than the outer diameter of the rod, thereby locking the rod into position relative to the spring;
• and
• wherein the release blade, when rotated through an acute angle, slightly uncoils the spring, unlocking the rod's relative position with respect to the spring;
• an actuator attached to the release blade;
• and
• an over-ride mechanism;
• wherein the rod anchor hole is attached to one of the two surfaces and the over-ride mechanism is attached to the other of the two surfaces;
• wherein, when activated, the actuator, independent of the over-ride mechanism, can rotate the release blade through an acute angle, unlocking the rod's relative position with respect to the spring;
• and
• wherein the over-ride mechanism, independent of the actuator, can rotate the release blade through an acute angle, unlocking the rod's relative position with respect to the spring.
