Abstract:
1. A method for operating a support assembly on a structure having an elevated surface capable of supporting a person moving about on same, the structure comprising a guide mountable on the support surface, a base adapted to engage the guide and capable of movement along said guide while remaining engaged therewith, and a support structure including a first portion that is pivotally connected to the base and a handle with a link spaced away from the based, a lock on the handle for selectively locking the support structure in an intermediate attitude relative to said base at an inclination between a generally upstanding attitude and a generally horizontal attitude, and a braking means for selectively locking the base in a desired position relative to said guide, the method comprising the steps of: securing a harness with at least a clap to a person; securing the at least a clap to the link on the handle; grasping the handle; grasping the lock for pivotally disengaging the support structure from the base; pivoting the support structure to a different attitude relative to said base in an intermediate attitude; releasing the lock for securing the support structure at the different attitude; engaging the braking means to release the base in relation to the guide; moving the base in relation to the guide; and disengaging the braking means to secure the base in relation to the guide.
