Abstract
One embodiment includes an assembly with a movable column with an upper end and a lower end, wherein the lower end includes a recessed opening. The assembly also includes a locking foot assembly with a base foot and a locking mechanism. The locking mechanism includes a latch which is spring biased and at least partially extends outward from the base foot such that the latch comes into contact with the lower end of the movable column and is retractable inward into the base foot when the spring is compressed, such that the latch of the locking mechanism can both engage and disengage the recessed opening in the lower end of the movable column.
